[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field of an automatic crimping machine for crimping a crimping connector (hereinafter, simply referred to as a connector) to an electric wire, and a connector for successively receiving and holding the crimped connectors to the electric wire. Regarding receiving device.

[0002]

2. Description of the Related Art Generally, a connector is pressed against the front end of an electric wire pulled out from a fixed chuck, the front end of the electric wire is clamped by a movable chuck and moved forward, and the electric wire is cut by a pressure welding mechanism to cut the electric wire. automatic welding machine is known which is adapted to press the connector into the end (for example, Japanese Application Rights 7
No. -59960 see (JP-A-8-235945)). When sending a work in which connectors are pressed against both ends of the cut wire to the side, the connectors at both ends are transferred to two parallel receiving rails, and the feed claw mechanism sequentially feeds them forward along the receiving rails. However, there is also known an automatic pressure welding machine which is designed to be discharged to the outside of the machine (for example, JP-A-9-99).
943).

[0003]

When the connectors at both ends of the electric wire are transferred to the receiving rail in the automatic crimping machine having the movable chuck, the discharge position of the movable chuck changes back and forth according to the change in the cutting length of the electric wire. In accordance with this, it is necessary to change the receiving position of the receiving rail corresponding to the movable chuck back and forth. This movable side receiving rail is called a movable receiving rail, but in order for the connector to stably transfer from the movable chuck to the movable receiving rail,
It is important to prevent misalignment between the movable chuck at the discharge position and the movable receiving rail at the receiving position. To this end, the movable receiving rail must be moved with high accuracy, and the movable receiving rail must be securely fixed so as not to move after the movement. To solve this problem,
The present inventor has considered moving the movable chuck and the movable receiving rail individually by using two servo motors. In this way, by synchronizing the operation of the servo motor, the above-mentioned positional deviation is unlikely to occur, and by stopping the operation of the servo motor on the side of the movable receiving rail after the movement of the movable receiving rail, the position of the movable receiving rail can be changed. Can be fixed.
However, the proposed device requires two servomotors, and thus has a problem of high cost.

Therefore, the present inventor connects the movable receiving rail to the movable chuck when the movable chuck moves to the discharging position, and moves the movable receiving rail together with the movable chuck, so that the above-mentioned displacement does not occur. Thought of doing so. Further, the movable receiving rail is placed on the traveling rail and moved, and the rod of the air cylinder provided on the movable receiving rail is pressed against the traveling rail to lock the movable receiving rail on the traveling rail, thereby fixing the position of the movable receiving rail. Thought to do. By doing so, the cost can be reduced as compared with the case where two servo motors are used. However, the proposed device has the following drawbacks. That is, it is difficult to obtain a sufficient locking force with the air pressure normally supplied in the factory. In addition, the movable receiving rail tilts due to the reaction force of the protruding force of the rod. Furthermore, if the air supply is stopped at a turning point such as at the end of a day's work, the air leakage will reduce the locking force. Therefore, this may cause the positional deviation.

An object of the present invention is to move the movable receiving rail together with the movable chuck, and also to provide a guide rail independent of the supporting mechanism of the movable receiving rail as exemplified by the traveling rail to provide the movable receiving rail. By grasping the guide rail with the clamp released from the rail and changing the tightening force to fix the position of the movable receiving rail or release it, the problems of the above proposed device can be solved all at once. It is to provide a receiving device, and further to provide an automatic crimping machine equipped with the crimping connector receiving device.

[0006]

In order to achieve the above-mentioned object, the first aspect of the present invention is that the front end of an electric wire to which a connector is press-contacted is clamped by a movable chuck, moved to the front of the press-contacting mechanism, and cut by the press-contacting mechanism. After the rear end of the wire is pressed into contact with the connector held on the pressure contact table, the connector at the rear end of the wire discharged from the pressure contact table is transferred to the fixed receiving rail and at the same time discharged from the movable chuck at the discharge position. Is a receiving device for a press-connecting connector that receives a connector at the front end of the electric wire at a receiving position, the movable chuck being provided so as to extend parallel to the fixed receiving rail and movable parallel to the moving direction of the movable chuck, and to be at the discharge position. The movable receiving rail that receives the connector discharged from the side to the side and holds it slidably to the side, and the movable receiving rail to the movable chuck so that the connector can be transferred. A locking mechanism that locks or locks the guide rail that is provided on the movable receiving rail and the guide rail that extends parallel to the moving direction of the movable receiving rail, and that changes the tightening force with the screw mechanism. Or with a clamp to release the lock,
When changing the discharge position of the movable chuck, unlock the clamp and move the movable receiving rail by the connecting mechanism.
Linked to the movable chuck it came to pick, characterized in that so as to control for unlocking and and clamping the connection by the connecting mechanism changing the discharge position of the movable chuck ends to the movable chuck of the movable receiving rail I am trying.

When the movable chuck changes the discharging position, the clamp is unlocked from the guide rail, and the connecting mechanism connects the movable receiving rail to the movable chuck that has arrived. The movable receiving rail moves by being dragged by the movable chuck, and the clamp moves along the guide rail. After the change of the discharge position of the movable chuck is completed, the connecting mechanism releases the connection of the movable receiving rail to the movable chuck and locks the clamp to the guide rail. In this way, since the movable receiving rail moves while being connected to the movable chuck, the movable chuck at the discharging position and the movable receiving rail at the receiving position will not be displaced even after the position is changed. Since the tightening force of the clamp is changed by the screw mechanism, a higher locking force can be obtained than when an air cylinder is used. In addition to the mechanism for supporting the movable receiving rail so that it can move in parallel with the moving direction of the movable chuck, an independent guide rail is provided, which is clamped to increase or decrease the clamping force of the clamp. The force to tilt the rail does not work. Further, since the screw mechanism is used, the locking force does not decrease even if the air supply is stopped at a turning point such as at the end of a day's work. Therefore, the displacement does not occur. Further, the cost is reduced as compared with the case where two servo motors are used.

According to a second aspect of the present invention, the front end of the electric wire to which the connector is pressed is held by the movable chuck and moved to the front of the press contact mechanism, and the rear end of the electric wire cut by the press contact mechanism is held on the press base. After the connector is pressed against the connector, the connector at the rear end of the wire discharged from the pressure welding table is transferred to the fixed receiving rail, and at the same time, the connector at the front end of the wire discharged from the movable chuck at the discharge position is received at the receiving position. A connector receiving device, a traveling rail provided in parallel with a moving direction of a movable chuck, and a slide rail extending in parallel with a fixed receiving rail and slidable on the traveling rail. The movable receiving rail that receives the connector discharged to the side and holds it so that it can slide laterally, and the movable receiving rail are mounted on a movable chuck so that the connector can be transferred. It has a connection mechanism that ties or releases the connection, a guide rail that is provided parallel to the traveling rail, a clamp that is provided on the movable receiving rail and that holds the guide rail, and a screw mechanism that changes the tightening force of the clamp. A switching mechanism that rotates the mechanism to lock the clamp to the guide rail or unlocks the clamp from the guide rail, and unlocks the clamp from the guide rail when a command to change the discharge position of the movable chuck is issued. When the movable receiving rail is connected to the movable chuck that has come to pick up, and when the moving position of the movable chuck is changed, the movable receiving rail is released from the movable chuck and the clamp is locked to the guide rail. And a position change control means for controlling the switching mechanism.

When a command to change the discharge position of the movable chuck is issued, the switching mechanism releases the lock of the clamp to the guide rail, and the connecting mechanism connects the movable receiving rail to the movable chuck that has come to the arrival. The movable receiving rail is dragged by the movable chuck and moves on the traveling rail, and the clamp moves along the guide rail. After the change of the discharge position of the movable chuck is completed, the coupling mechanism releases the coupling of the movable receiving rail to the movable chuck, and the switching mechanism locks the clamp to the guide rail. In this way, since the movable receiving rail moves while being connected to the movable chuck, the movable chuck at the discharging position and the movable receiving rail at the receiving position will not be displaced even after the position is changed. Since the tightening force of the clamp is changed by the screw mechanism, a higher locking force can be obtained than when an air cylinder is used. Further, an independent guide rail is provided separately from the traveling rail, and the guide rail is gripped by the clamp to increase or decrease the clamping force of the clamp, so that the force for tilting the movable receiving rail does not act. Further, since the screw mechanism is used, the locking force does not decrease even if the air supply is stopped at a turning point such as at the end of a day's work. Therefore, the displacement does not occur. Further, the cost is reduced as compared with the case where two servo motors are used.

The screw mechanism is a bolt that penetrates one end of the opposite ends of the clamp and is screwed to the other end, and the switching mechanism is A pinion provided on the bolt, a rack that meshes with the pinion, and a reciprocating mechanism that reciprocates the rack.

With this configuration, when the reciprocating mechanism moves the rack, the pinion turns the bolt, the screwing position of the bolt changes, the gap size of the opening of the through hole changes, and the clamping force of the clamp changes. Further, the clamp and switching mechanism can be realized with a simple structure. By rotating the bolt or pinion with a wrench or the like, the clamp can be manually locked or unlocked on the guide rail. In addition, the stroke of the reciprocating mechanism can be shortened as compared with the mechanism that extends the arm in the radial direction from the bolt.

After moving and stopping, the fixed chuck and the press-contact mechanism tension the wire to sandwich it, cut the wire with the press-connecting mechanism, press the connector to the cut ends of the wire, and press it to both ends of the cut wire. The main control means for controlling the fixed chuck, the movable chuck and the pressure contact mechanism so that the connector is ejected to the side, and when the command to change the eject position of the movable chuck is issued, the lock of the clamp on the guide rail is released and picked up. The movable receiving rail is connected to the movable chuck, and when the discharge position of the movable chuck is changed, the movable receiving rail is connected to the movable chuck. It is characterized in that a position changing control means for controlling the coupling mechanism and the switching mechanism to perform the locking of the dividing and clamping of the guide rail.

As described above, since the movable receiving rail 720 moves while being connected to the movable chuck 300, the movable chuck 300 at the discharging position and the movable receiving rail 720 at the receiving position do not shift even after the position change. Since the tightening force of the clamp 750 is changed by the screw mechanism 761, a higher locking force can be obtained than when an air cylinder is used. As an example, when the M10 bolt 761 was used, a clamp tightening force of about 900 kg was obtained. This is an order of magnitude more fixing force than when the movable receiving rail is locked to the traveling rail by pressing the rod of the air cylinder provided on the movable receiving rail against the traveling rail. In addition to the traveling rail 710,
An independent guide rail 740 is provided, and this is clamped 7
Since it is gripped by 50 and the tightening force of the clamp 750 is increased or decreased, the force for tilting the movable receiving rail 720 does not act. Furthermore, even if the air supply is stopped at a turning point such as at the end of a day's work, the locking force does not decrease. for that reason,
The above displacement does not occur. As described above, since the movable chuck 300 in the discharging position and the movable receiving rail 720 in the receiving position are not displaced from each other, the connector CF
Can be stably transferred from the movable chuck 300 to the movable receiving rail 720. Further, the cost is significantly reduced as compared with the case where two servo motors are used.

This embodiment does not limit the shape of the clamp of the present invention, and does not limit the structure of the switching mechanism of the present invention. The present invention also includes an embodiment in which the screw mechanism is rotated by a known structure to change the clamping force of the clamp to lock or unlock the guide rail. However, if the forms of the clamp 750 and the switching mechanism 760 as described in the above embodiment are adopted, the clamp and switching mechanism can be realized with a simple structure. Further, if the bolt 761 or the pinion 762 is turned with a wrench or the like, the clamp 750 can be manually locked to the guide rail 740 or the clamp 750 can be unlocked from the guide rail 740. As a modified example of the switching mechanism 760 including the bolt 761, the pinion 762, the rack 763, and the reciprocating mechanism 764,
There is a switching mechanism including a bolt 761 having a similar structure, an arm extending from the bolt 761 in the radial direction, and a reciprocating mechanism such as an air cylinder for rotating the arm. However, the above-described embodiment is advantageous in that the stroke of the reciprocating mechanism becomes shorter.

The present invention includes an embodiment in which the fixed receiving rail and the movable receiving rail do not have a continuity checker, and the fixed receiving rail and the movable receiving rail perform only the ejecting function of the connector. On the other hand, in the above-described embodiment, the movable receiving rail 720 is connected to the connector CF held by the movable receiving rail 720, and a conduction test is performed for conducting a conduction test between the movable receiving rail 720 and the corresponding connector CR held by the fixed receiving rail 600. An inspector 772 is provided. Therefore, the movable chuck 300 located at the discharge position and the movable receiving rail 72 located at the receiving position.
Since the positional deviation from 0 does not occur, the connector CF is surely guided to the continuity tester 772, so that the continuity test of the connector CF can be performed without omission.

In the above embodiment, the movable receiving rail 720 is placed on the traveling rail 710 so as to be slidable. However, the present invention includes an embodiment in which the movable receiving rail is movably provided in parallel with the moving direction of the movable chuck by using another known mechanism. In the above embodiment, the automatic pressure welding machine is entirely controlled by the control means. However, it is possible to perform the same operation as that of the above-described embodiment by providing a sensor and an electric circuit for each mechanism, and operating a limit switch or the like when the mechanisms contact each other to coordinate the operation of each mechanism. The present invention includes such an embodiment. Further, the control means is not limited to digital control by a computer including a CPU, a memory, etc., and may be analog control or mechanical control.

In the receiving device for the press contact connector according to the first and second aspects of the present invention, even after the position is changed, the movable chuck at the discharge position and the movable receiving rail at the receiving position are not displaced, so that the connector can be moved. It is possible to stably transfer from the chuck to the movable receiving rail. Further, the cost can be significantly reduced as compared with the case where two servo motors are used.

According to the third aspect, the clamp and switching mechanism can be realized with a simple structure. Further, if the bolt or pinion is turned with a wrench or the like, the clamp can be manually locked or unlocked on the guide rail. In addition, the stroke of the reciprocating mechanism can be shortened as compared with the mechanism that extends the arm in the radial direction from the bolt.

According to the fourth aspect of the present invention, since the positional displacement between the movable chuck at the discharging position and the movable receiving rail at the receiving position does not occur, the connector can be surely guided to the continuity tester. The continuity test can be performed without omission.

According to another aspect of the present invention, there is provided an automatic crimping machine equipped with a receiving device for a crimping connector, which comprises a movable chuck at a discharging position and a movable receiving rail at a receiving position even after a position change in a step of automatically crimping an electric wire to the connector. Since the positional deviation does not occur, the connector can be stably transferred from the movable chuck to the movable receiving rail. Further, the cost can be significantly reduced as compared with the case where two servo motors are used.
