Description

Pneumatic automatic extraction and transfer device for to-be-detected spring piece of spring piece elasticity detector
Technical Field
The invention belongs to the technical field of automatic testing devices of electrical components, and particularly relates to a pneumatic automatic extraction and transfer device for a spring piece to be tested of a spring piece elasticity testing machine.
Background
The spring lamination mentioned above is a moving contact spring lamination, is a structural system component of a motor protector of a refrigeration compressor, is a structural system component of an overload protector of a single-phase alternating current motor of the refrigeration compressor, and provides effective protection for the over-temperature and overload of the temperature of the single-phase alternating current motor, and the structure of the spring lamination can be found in a large number of published Chinese patent documents, such as CN2218263Y (self-protection type refrigeration compressor thermal protector), CN2287339Y (refrigeration compressor motor protector), CN1207743C (thermal protector), CN2341305Y (current temperature composite type motor protector), and CN100356652C (overload protector of a single-phase alternating current motor), and the like. It is known from reading, but not limited to, the aforementioned patent documents, in particular from the reading of CN100356652C and in combination with the common general knowledge: when the movable contact on the movable contact spring sheet is in contact with the fixed contact of the base part of the pin, namely when the movable contact is closed with the fixed contact, the electric circuit is communicated, otherwise, the same example is adopted, so that the function of protecting the compressor motor, namely the function of protecting the single-phase alternating current motor is realized. Specifically, when the radiation of the electric heating wire or the aluminum cover or the external environment is lower than the sensing temperature at which the bimetallic strip can deform, the bimetallic strip resets, the ejector rod does not generate acting force on the free end of the spring strip (the movable contact is positioned at the free end of the spring strip), namely does not push the spring strip, and the movable contact upwards returns under the elastic restoring force of the spring strip to be closed with the static contact, so that the motor circuit is connected. See CN100356652C, page 6 of the specification.
As can be seen from the above description, the elasticity of the movable contact spring leaf as a structural system of the motor protector of the refrigeration compressor must meet the process requirements, which are: when the top rod pushes the free end, the elastic deformation of the top rod ensures that the movable contact on the top rod is separated from the static contact on the pin of the protector, and when the top rod does not push the free end, the top rod must return in time to make the movable contact and the static contact.
The prior art is lack of reasonable technical measures, and the detection of whether the elastic deformation of the spring piece meets the requirements mainly comprises the following three modes: firstly, acting or relieving action on the ejector rod through artificial preset force, and simultaneously observing whether a movable contact on the spring piece is in contact with or separated from a static contact by an online operator; secondly, the elasticity of the spring piece is judged by the hand feeling of workers; and thirdly, connecting the assembled motor starting protectors of the refrigeration compressors of the same batch in a circuit simulating actual use in a human spot check mode, so as to verify the elasticity of the movable contact spring piece. The first of the three aforementioned modes is deficient in that: the method has great blindness and subjectivity, because the method is difficult to judge by a relatively uniform judgment standard or even cannot judge by the relatively uniform judgment standard at all, and the detection efficiency is low, especially the detection result is different due to differences of responsibility, experience, emotion, working attitude and the like of a detector; the second of the three aforementioned modes also exists that the first mode described above differs from person to person and even the same person does not draw substantially the same result as to the elasticity of the same batch of movable contact spring pieces, even if the contrary conclusion is not excluded, and moreover the detection efficiency is very low; the third of the above three methods, although it can draw a relatively scientific and reasonable conclusion, cannot represent all the methods individually by spot inspection, i.e. there is a defect of dot coverage, so that the limitations are relatively large and the detection cost is high.
In view of the above-mentioned prior art, if a spring leaf elasticity tester can automatically perform a non-sparse and non-leaking same-standard test on each moving contact spring leaf, the above-mentioned technical problems can be readily solved. However, how to automatically and efficiently extract and transfer the to-be-tested spring leaf to be tested to the testing station (i.e., "testing station") is a technical problem that the spring leaf elasticity testing machine inevitably faces and must solve, but there is no teaching in the Chinese and foreign patent documents disclosed so far that any reference which helps to solve the technical problem is available. The applicant has made an advantageous design for this purpose, in which context the solutions to be described below are produced.

The feeding nozzle longitudinal displacement cylinder fixing base 31 is provided on the table 1 at a position corresponding to the left rear side of the vibrator adjusting frame support base 21, and when the feeding nozzle lateral displacement cylinder 34 of the automatic feeding mechanism assembly 3 drives the feeding nozzle lateral displacement cylinder slider 341 to be displaced left and right, the feeding nozzle 35 is displaced left and right between the upper side corresponding to the movable contact spring piece guide groove 241 and the upper side of the receiving mechanism 4.
In the present embodiment, the loading nozzle longitudinal displacement cylinder 32 and the loading nozzle lateral displacement cylinder 34 are air cylinders.
As can be seen from the schematic view of fig. 1, the left end port of the aforementioned movable contact spring piece guide groove 241 is closed, and the right end port is configured to be open (i.e., not closed) so as to guide and supply the movable contact spring piece 10 into the automatic feeding mechanism assembly 3; the loading suction nozzle 35 of the automatic loading mechanism assembly 3 moves left and right between the upper side corresponding to the movable contact spring piece guiding groove 241 and the upper side corresponding to the material receiving mechanism 4 during operation. The position change distance measuring mechanism 9 of the head part of the movable contact spring piece, which is arranged on the workbench 1 corresponding to the position between the front material taking mechanism 7 and the rear material taking mechanism 8, also corresponds to the side surface of the leading-out groove feeding port 121 of the qualified movable contact spring piece leading-out groove 12; the deformation measuring mechanism 6 of the movable contact spring piece also corresponds to the right side of the feed inlet 121 of the leading-out groove; the first material receiving box I13 a of the unqualified moving contact spring piece and the second material receiving box II 13b of the unqualified moving contact spring piece are arranged on the workbench 1 in an unfixed or fixed state (the former is selected in the embodiment).
When the movable contact spring piece vibrating tray 11 is in an operating state, the movable contact spring piece 10 to be detected in the movable contact spring piece vibrating tray is introduced into the movable contact spring piece guiding groove 241 of the spring piece guiding rail 24 of the structural system of the vibration guiding mechanism 2 at the position of the vibrating tray cavity 111, and under the operation of the vibrator 23, the spring piece guiding rail 24 is inclined from right to left (higher right and lower left), so that the movable contact spring piece 10 slides from right to left along the movable contact spring piece guiding groove 241 until being blocked by the wall body at the left notch part of the movable contact spring piece guiding groove 241, and the movable contact spring piece is extracted (sucked) by the feeding suction nozzle 35 and transferred to the station where the receiving mechanism 4 is located.
As can be seen from the schematic diagram of fig. 2, a first position signal collector seat i 322 is fixed at the top and the bottom of the feeding nozzle longitudinal displacement acting cylinder 32, a first position signal collector i 3221 is arranged on the first position signal collector seat i 322, when the first slider stopper i 3211 of the feeding nozzle longitudinal displacement acting cylinder slider 321 contacts with the first position signal collector i 3221 on the first position signal collector seat i 322 at the top, which is not shown in the figure, it indicates that the feeding nozzle longitudinal displacement acting cylinder slider 321 drives the feeding nozzle lateral displacement acting cylinder 34 to rise upward to the limit, and when the feeding nozzle longitudinal displacement acting cylinder slider 321 displaces downward until the first slider stopper i 3211 of the feeding nozzle longitudinal displacement acting cylinder slider 321 contacts with the first position signal collector i 3221 on the first position signal collector seat i 322 at the bottom, it indicates that the feeding nozzle longitudinal displacement acting cylinder slider 321 drives the feeding nozzle lateral displacement acting cylinder 34 to fall downward to the limit. Therefore, the ascending and descending strokes of the loading nozzle longitudinal displacement acting cylinder sliding block 321 are limited between the top and bottom first position signal collector seats I322, namely between the top and bottom first position signal collectors I3221.
In fig. 2, a second position signal collector seat ii 342 is shown, which is provided at each of the left and right ends of the feeding nozzle lateral displacement acting cylinder 34, and a second position signal collector ii 3421 is provided on the second position signal collector seat ii 342, and when the feeding nozzle lateral displacement acting cylinder block 341 is displaced leftward to such an extent that the second block ram ii 3411 is in contact with the second position signal collector ii 3421 on the left one of the second position signal collector seats ii 342, it indicates that the feeding nozzle lateral displacement acting cylinder block 341 is displaced leftward to the limit, and when the feeding nozzle lateral displacement acting cylinder block 341 is displaced rightward to such an extent that its second block ram ii 3411 is in contact with the second position signal collector ii 3421 on the right one of the second position signal collector seats 342 ii, it indicates that the feeding nozzle lateral displacement acting cylinder block 341 is displaced rightward to the limit. The loading nozzle 35 is raised or lowered correspondingly at the same time when the loading nozzle lateral displacement acting cylinder 34 is raised or lowered by the loading nozzle longitudinal displacement acting cylinder slider 321, and similarly, the loading nozzle 35 is also displaced leftwards or rightwards relatively when the loading nozzle lateral displacement acting cylinder slider 341 is displaced leftwards or rightwards.
When feeding is required, namely when feeding is required to be carried out to the receiving mechanism 4 by the automatic feeding mechanism assembly 3 (the material is the 'movable contact spring piece 10' to be measured), firstly, the feeding suction nozzle longitudinal displacement acting cylinder slider 321 is upwards lifted by the feeding suction nozzle longitudinal displacement acting cylinder 32, then, the feeding suction nozzle transverse displacement acting cylinder slider 341 is rightwards displaced by the operation of the feeding suction nozzle transverse displacement acting cylinder 34, so that the feeding suction nozzle 35 corresponds to the upper part of the left end of the movable contact spring piece guiding groove 241 of the spring piece guiding rail 24, then, according to the opposite process, the feeding suction nozzle longitudinal displacement acting cylinder 321 is downwards displaced by the feeding suction nozzle longitudinal displacement acting cylinder 32, so that the feeding suction nozzle 35 descends, the feeding nozzle head 351 of the feeding nozzle 35 sucks the moving contact spring piece 10 to be detected in the moving contact spring piece guide groove 241 under the action of negative pressure (sucking one piece at a time), then the feeding nozzle longitudinal displacement acting cylinder 32 makes the feeding nozzle longitudinal displacement acting cylinder slider 321 move upwards, then the feeding nozzle transverse displacement acting cylinder 34 works reversely to make the feeding nozzle transverse displacement acting cylinder slider 341 move leftwards, the feeding nozzle 35 correspondingly moves leftwards to the upper side of the station corresponding to the receiving mechanism 4 under the condition that the feeding nozzle head 351 sucks the moving contact spring piece 10, then the feeding nozzle longitudinal displacement acting cylinder 32 makes the feeding nozzle longitudinal displacement acting cylinder slider 321 move downwards to make the feeding nozzle 35 also move downwards, and the feeding nozzle 35 at the moment is changed from negative pressure to positive pressure to release the previously sucked material, namely the moving contact 10 to the receiving mechanism 4. The foregoing process is repeated.
Already mentioned above: the loading nozzle longitudinal displacement action cylinder 32 and the loading nozzle transverse displacement action cylinder 34 are both air cylinders, and the action cylinders referred to below are also air cylinders. In this embodiment, the movement of the loading nozzle longitudinal and lateral displacement acting cylinder sliding blocks 321 and 341 is respectively operated by the acting cylinder columns of the loading nozzle longitudinal and lateral displacement acting cylinders 32 and 34, and the following acting cylinder sliding blocks are the same as those mentioned in the same example. Fig. 2 also shows a feed nozzle inlet/outlet air line connection 352 of the feed nozzle 35, which in the operating state is provided with a connection and is connected via a line to a vacuum generating device, such as a vacuum pump or the like, which is preferably arranged in the aforementioned support box 14.

The structural form and the action mechanism of the material receiving acting cylinder 42 are similar to those of the material loading suction nozzle transverse displacement acting cylinder 34, so that the applicant does not need to describe the material receiving acting cylinder. As can be seen from fig. 1 and fig. 3 to 4, when the receiving cylinder 42 makes the receiving cylinder block 421 move forward or backward alternatively, the receiving cylinder block 421 drives the front and rear movable contact spring piece detecting bearing seats 44 and 45 to move forward or backward alternatively.

Referring to fig. 3 in conjunction with fig. 1, the aforesaid movable contact spring plate pressing and releasing mechanism 5 includes a front pressing and releasing actuator 51 and a rear pressing and releasing actuator 52, the front pressing and releasing actuator 51 includes a front pressing claw up-and-down displacement driving action cylinder fixing frame 511, a front pressing claw up-and-down displacement driving action cylinder 512, a front pressing claw fixing frame 513 and a front pressing claw 514, the front pressing claw up-and-down displacement driving action cylinder fixing frame 511 is disposed in a longitudinal state at a position corresponding to the front of the left end of the aforesaid feeding nozzle lateral displacement action cylinder 34, and the lower end of the front pressing claw up-and-down displacement driving action cylinder fixing frame 511 is fixed to the aforesaid working table 1 by screws, the front pressing claw up-and-down displacement driving action cylinder 512 is fixed to the left side of the upper end of the front pressing claw up-and-down displacement driving action cylinder fixing frame 511 in a longitudinal state, the front pressing claw fixing frame is fixed to the left side of the front pressing claw up-and-down displacement driving action cylinder sliding block 5121 of the front pressing claw fixing frame 512, the front pressing claw fixing frame 512 is fixed to the lower end of the front pressing claw fixing frame 513 and corresponds to the upper side of the movable contact spring plate bearing seat 44 of the aforesaid front pressing claw fixing frame 513; the rear pressing and releasing actuator 52 includes a rear pressing claw vertical displacement driving cylinder fixing bracket 521, a rear pressing claw vertical displacement driving cylinder 522, a rear pressing claw fixing bracket 523 and a rear pressing claw 524, the rear pressing claw vertical displacement driving cylinder fixing bracket 521 is disposed in a longitudinal state at a position corresponding to the rear of the left end of the feeding nozzle lateral displacement acting cylinder 34, and the rear pressing claw vertical displacement driving cylinder fixing bracket 521 also corresponds to the rear of the front pressing claw vertical displacement driving cylinder fixing bracket 511, the lower end of the rear pressing claw vertical displacement driving cylinder fixing bracket 521 is fixed to the table 1 by a screw, the rear pressing claw vertical displacement driving cylinder 522 is fixed to the left side of the upper end of the rear pressing claw vertical displacement driving cylinder fixing bracket 521 in a longitudinal state, the rear pressing claw fixing bracket 523 is fixed to the left side of the rear pressing claw vertical displacement driving cylinder slider 5221 of the rear pressing claw vertical displacement driving cylinder fixing bracket 522, the rear pressing claw fixing bracket 524 is fixed to the side of the lower end of the rear pressing claw fixing bracket 523, and detects the upper side of the load bearing seat 45 corresponding to a point.

The structural form and the action mechanism of the front pressing claw up-and-down displacement driving acting cylinder 512 and the rear pressing claw up-and-down displacement driving acting cylinder 522 of the structural system of the movable contact spring piece pressing and releasing mechanism 5 are similar to or similar to those of the feeding nozzle longitudinal displacement acting cylinder 32 of the structural system of the automatic feeding mechanism assembly 3, so that the applicant does not describe any further. From the illustrations of fig. 1 and 3, it can be ascertained without any doubt that: the front pressing and releasing actuator 51 presses or releases the movable contact spring piece 10 on the front movable contact spring piece detection bearing seat 44, and the rear pressing and releasing actuator 52 presses or releases the movable contact spring piece 10 on the rear movable contact spring piece detection bearing seat 45. Taking the former pressing and releasing actuator 51 as an example, when the automatic feeding mechanism assembly 3 feeds the movable contact spring piece 10 to the front movable contact spring piece detection bearing seat 44, i.e. after the front movable contact spring piece detection bearing seat 44 receives the movable contact spring piece 10, the front pressing claw up-and-down displacement driving acting cylinder 512 operates to make the front pressing claw up-and-down displacement driving acting cylinder block 5121 displace downward, the front pressing claw up-and-down displacement driving acting cylinder block 5121 drives the front pressing claw fixing block 513 to displace downward together with the front pressing claw 514 correspondingly and to press the movable contact spring piece base 102 (also called "movable contact spring piece fixing block") of the movable contact spring piece 10 shown in fig. 7, and at the same time, the movable contact spring piece front detection table lift pin 61 of the structural system of the movable contact spring piece deformation measurement mechanism 6 to be described below pushes the downward side of the movable contact spring piece head 101 of the movable contact spring piece 10 upward, i.e. the test is performed. After the test is completed, the front pressing claw up-and-down displacement driving acting cylinder 512 works reversely, so that the front pressing claw up-and-down displacement driving acting cylinder slider 5121, together with the front pressing claw fixing seat 513 and the front pressing claw 514, moves upwards to release the compression on the movable contact spring piece 10, meanwhile, the front detection table thimble lifting device 61 of the movable contact spring piece releases the pushing on the head part 101 of the movable contact spring piece, the detected movable contact spring piece 10 is taken away from the front movable contact spring piece detection bearing seat 44 by a front material taking mechanism 7 which will be described in detail below, if the movable contact spring piece is qualified, the detected movable contact spring piece is released to the qualified movable contact spring piece leading-out groove 12, and if the detected movable contact spring piece is unqualified, the detected movable contact spring piece is released to the first material receiving box I13 a of the unqualified movable contact spring piece. The qualified and unqualified movable contact spring pieces are judged by the movable contact spring piece deformation measuring mechanism 6 and the movable contact spring piece head position change distance measuring mechanism 9, and signals are fed back to an electric controller 15 which is arranged at the right end of the workbench 1 and is shown in figure 6, and the PLC (programmable logic controller) of the electric controller 15 controls the stroke of a front material taking suction nozzle translation acting cylinder 75 of a front material taking mechanism 7 which is described below, so that the qualified or unqualified movable contact spring pieces 10 are released to the correct position, namely, the qualified movable contact spring piece lead-out groove 12 or the unqualified movable contact spring piece first material receiving box I13 a. Since the operation of the rear press and release actuator 52 is the same as that of the front press and release actuator 51, the explanation thereof will not be repeated.
Referring to fig. 3 and with reference to fig. 1, the movable contact spring piece deformation measuring mechanism 6 includes a movable contact spring piece front detection table thimble lifting device 61 and a movable contact spring piece rear detection table thimble lifting device 62, the movable contact spring piece front detection table thimble lifting device 61 includes a front detection table thimble lifting cylinder fixing frame 611, a front detection table thimble lifting cylinder 612, a front detection table fixing frame 613, a front detection table 614 and a front detection table thimble 615, the front detection table thimble lifting cylinder fixing frame 611 is disposed in a longitudinal state at a position corresponding to the right side of the qualified movable contact spring piece lead-out groove 12, i.e. at a position corresponding to the right side of the lead-out groove feed inlet 121, and the lower end of the front detection table thimble lifting cylinder fixing frame 611 is fixed to the front detection table thimble lifting cylinder fixing frame transition connecting seat 6111, the front detection table thimble lifting action cylinder fixing frame transition connecting seat 6111 is fixed with the workbench 1 through screws, the front detection table thimble lifting action cylinder 612 is fixed on the left side of the upper end of the front detection table thimble lifting action cylinder fixing frame 611, the front detection table fixing seat 613 is fixed with the left side of the front detection table thimble lifting action cylinder slide block 6121 of the front detection table thimble lifting action cylinder 612, the front detection table 614 corresponds to the left side of the front detection table fixing seat 613 and is contacted with the left side surface of the front detection table fixing seat 613, the front detection table thimble 615 is formed on the front detection table 614 and is fixed with the front detection table fixing seat thimble positioning seat 6131 formed on the upper part of the front detection table fixing seat 613 by the base part of the front detection table thimble 615, and the upper end of the front detection table thimble 615 corresponds to the lower part of the bearing seat thimble yielding hole 443 shown in fig. 4; the rear detection gauge needle lifting device 62 for the movable contact spring piece includes a rear detection gauge needle lifting action cylinder fixing frame 621, a rear detection gauge needle lifting action cylinder 622, a rear detection gauge fixing seat 623, a rear detection gauge 624 and a rear detection gauge needle 625, the rear detection gauge needle lifting action cylinder fixing frame 621 is disposed in a longitudinal state at a position corresponding to the right side of the qualified movable contact spring piece lead-out slot 12, i.e., at a position corresponding to the right side of the lead-out slot feed inlet 121, and the lower end of the rear detection gauge needle lifting action cylinder fixing frame 621 is fixed to a rear detection gauge needle lifting action cylinder fixing frame transition connecting seat 6211, the rear detection gauge needle lifting action cylinder fixing seat 6211 is fixed to the table 1 by screws, the rear detection gauge needle lifting action cylinder 622 is fixed to the front side of the upper end of the rear detection gauge needle lifting action cylinder fixing frame 621, the rear detection gauge fixing seat 623 is fixed to the front side of a rear detection gauge needle lifting action cylinder sliding block 6221 of the rear detection gauge needle lifting action cylinder 622, the rear detection gauge 624 corresponds to the front side of the rear detection gauge fixing seat 623 and is attached to the rear detection gauge needle lifting action sliding block 6221 of the rear detection gauge needle lifting action table mounting seat, the rear detection table mounting seat 443 (the rear detection gauge needle mounting seat is equivalent to the detection table mounting seat 624, the rear detection table mounting seat).
In the present embodiment, the front and rear detection gauge pin lifting cylinders 612 and 622 are cylinders.
As shown in fig. 3, an adjustment fixing hole is formed at the upper end of the front detection gauge thimble lifting action cylinder fixing frame transition connecting seat 6111, and the front detection gauge thimble lifting action cylinder fixing frame 611 is fixed to the upper end of the front detection gauge thimble lifting action cylinder fixing frame transition connecting seat 6111 at a position corresponding to the adjustment fixing hole; an adjusting fixing hole is formed in the upper end of the rear detection gauge thimble lifting action cylinder fixing frame transition connecting seat 6211, and the rear detection gauge thimble lifting action cylinder fixing frame 621 is fixed to the upper end of the rear detection gauge thimble lifting action cylinder fixing frame transition connecting seat 6211 at a position corresponding to the adjusting fixing hole.
The transition connection seat 6111 of the front detection gauge thimble lifting action cylinder fixing frame and the transition connection seat 6211 of the rear detection gauge thimble lifting action cylinder fixing frame are in an L shape.
Since the structural form and the operation mechanism of the front and rear detecting gauge pin lifting/lowering cylinders 612 and 622 are similar to those of the feeding nozzle longitudinal displacement cylinder 32, the applicant does not give any further explanation. Taking the front detection gauge pin elevating device 61 of the movable contact spring piece as an example, under the operation of the front detection gauge pin elevating cylinder 612, the front detection gauge pin elevating cylinder slider 6121 is displaced upward to drive the front detection gauge fixing base 613, the front detection gauge 614 and the front detection gauge pin 615 to displace upward correspondingly, so that the front detection gauge pin 615 pushes the movable contact spring piece head 101 of the movable contact spring piece 10 on the front movable contact spring piece detection bearing base 44 upward, because the movable contact spring piece 10 is usually made of a metal sheet with good elasticity and is conductive, such as a copper sheet, the movable contact spring piece head 101 is lifted upward when the front detection gauge pin 615 pushes the movable contact spring piece head 101 upward, and the pushing force is revealed by the front detection gauge 614 and can be fed back to the electrical controller 15, and at the same time, the degree of upward rising (lifting) of the movable contact spring piece head 101 can be detected by the front detector 92 of the structural system of the movable contact spring piece head position change distance detecting mechanism 9, which will be described in detail below, and fed back to the electrical controller 15. In the foregoing process, the movable contact spring pieces 10 of the same specification and batch, that is, the starters of the same batch are under the same pushing force, if the elasticity of the movable contact spring piece head 101 is insufficient, that is, the movable contact spring piece head does not reach the set value range or exceeds the set value range, the movable contact spring piece head is an unqualified movable contact spring piece 10, and otherwise, the movable contact spring piece head is a qualified movable contact spring piece 10. Since the working process of the rear detection gauge thimble lifting device 62 of the movable contact spring piece is the same as that of the front detection gauge thimble lifting device 61 of the movable contact spring piece, the applicant does not give further details.
Continuing with fig. 1, the preferred, but not absolutely limited, construction of the front take off mechanism 7 described above is as follows: comprises a front material taking suction nozzle horizontal displacement acting cylinder fixing frame 71, a front material taking suction nozzle horizontal displacement acting cylinder 72, a front material taking suction nozzle lifting acting cylinder 73, a front material taking suction nozzle translation acting cylinder fixing platform 74, a front material taking suction nozzle translation acting cylinder 75, a front material taking suction nozzle fixing seat 76 and a front material taking suction nozzle 77, the lower part, namely the bottom of the front material taking suction nozzle horizontal displacement acting cylinder fixing frame 71 is arranged on the workbench 1 at the position corresponding to the front position of the left side of the unqualified movable contact spring piece first material receiving box I13 a and is fixed with the workbench 1 through screws, the upper part of the front material taking suction nozzle horizontal displacement acting cylinder fixing frame 71 extends upwards in the direction far away from the workbench 1 in a longitudinal state, the front material taking suction nozzle horizontal displacement acting cylinder 72 is fixed with the rear side of the upper part of the front material taking suction nozzle horizontal displacement acting cylinder fixing frame 71 in a horizontal state, the front material taking suction nozzle lifting action cylinder 73 is fixed at the rear side of the front material taking suction nozzle lifting action cylinder base 731 in a longitudinal state, the front material taking suction nozzle lifting action cylinder base 731 is fixed with the rear side of the front material taking suction nozzle horizontal displacement action cylinder slide block 721 of the front material taking suction nozzle horizontal displacement action cylinder 72, the front material taking suction nozzle translation action cylinder fixing platform 74 is fixed with the upper part of the front material taking suction nozzle lifting action cylinder slide block 732 of the front material taking suction nozzle lifting action cylinder 73, the front material taking suction nozzle translation action cylinder 75 is fixed at the upward side of the front material taking suction nozzle translation action cylinder fixing platform 74 in a horizontal state, the front material taking suction nozzle fixing base 76 is fixed at one end of the front material taking suction nozzle translation action cylinder slide block 751 of the front material taking suction nozzle translation action cylinder 75 facing the material receiving mechanism 4, and the rear end of the front material taking suction nozzle fixing base 76 is stretched out of the end surface of one end of the front material taking suction nozzle translation action cylinder slide block 751 facing the material receiving mechanism 4, the front pickup nozzle 77 is fixed to the rear end of the front pickup nozzle holder 76 and detects the upper side of the carrier holder 44 corresponding to the aforementioned front movable contact spring piece. In fact, the front pickup nozzle 77 and the front pickup nozzle holder 76 are integrally formed with each other and substantially identical to the structure of the loading nozzle 35, and thus, a detailed description thereof will not be provided.
Since the actual structure and mechanism of the aforementioned front pickup nozzle horizontal displacement action cylinder 72 and the front pickup nozzle translation action cylinder 75 are substantially the same as those of the aforementioned loading nozzle lateral displacement action cylinder 34 and will not be confused by those skilled in the art, the applicant is not presented with the same explanation as that of the above-mentioned loading nozzle lateral displacement action cylinder 34.
When the detected movable contact spring piece 10 is to be removed from the aforementioned front movable contact spring piece detection bearing seat 44, the front material taking suction nozzle lifting cylinder 73 is first operated to make the front material taking suction nozzle lifting cylinder slider 732 lift the front material taking suction nozzle lifting cylinder seat 731 together with the front material taking suction nozzle translation cylinder 75 upward, then the front material taking suction nozzle horizontal displacement cylinder slider 721 is moved leftward by the front material taking suction nozzle horizontal displacement cylinder 72, the front material taking suction nozzle lifting cylinder 73 and the front material taking suction nozzle translation cylinder 75 are also moved leftward until the front material taking suction nozzle translation cylinder 75 corresponds to the position of the front movable contact spring piece detection bearing seat 44 and the front suction nozzle 77 corresponds to the upper part of the front movable contact spring piece detection bearing seat 44, and since the detected movable contact spring piece 10 is already present on the front movable contact spring piece detection bearing seat 44 at this time, the front suction nozzle 77 actually corresponds to the upper part of the movable contact spring piece 10. At this time, the front material taking nozzle lifting cylinder 73 works reversely with respect to the above, and the front material taking nozzle translation cylinder fixing platform 74, the front material taking nozzle translation cylinder 75 and the front material taking nozzle 77 move downward due to the downward movement of the front material taking nozzle lifting cylinder slider 732, and the front material taking nozzle 77 sucks the movable contact spring piece 10 under the negative pressure (the principle is completely the same as that of the above-mentioned material feeding nozzle 35). Then, the front material taking nozzle elevating cylinder 73 operates in the reverse direction to displace the front material taking nozzle 77 upward in a state of holding the movable contact spring piece 10, and then the front material taking nozzle translation cylinder 75 displaces forward in the direction opposite to the previous direction to drive the front material taking nozzle 77 holding the movable contact spring piece 10 to displace forward accordingly. Then, the cylinder 72 is horizontally moved by the front material-taking suction nozzle to move in the opposite direction to the above direction, so that the front material-taking suction nozzle 77 corresponds to the material-feeding port 121 of the leading-out groove, and at the same time, the front material-taking suction nozzle 77 becomes positive pressure to release the qualified movable contact spring piece 10 to the qualified movable contact spring piece leading-out groove 12 and lead the same into the above material-holding box 1421. If the test result is unqualified, the front material taking suction nozzle translation action cylinder 75 continues to act, the front material taking suction nozzle translation action cylinder slide block 751 continues to displace forwards, so that the position of the previous front material taking suction nozzle 77 corresponding to the material inlet 121 of the leading-out groove is changed to be corresponding to the upper part of the unqualified movable contact spring piece first material receiving box I13 a, and the unqualified movable contact spring piece 10 is released into the unqualified movable contact spring piece first material receiving box I13 a.
