Description

Automatic spray coating system for the object to be coated}

The present invention relates to a coating device, which enables automatic transfer and recovery of a jig for fixing the object to be coated when the object to be coated is spray-coated using a spray gun, thereby enabling automation in the existing manual work. It is related to the spray automatic coating system of the painted body.

In general, the painting treatment process corresponds to a process performed at the completion stage of a product. It can be said that the process of enhancing the aesthetics of the product as well as one of the various needs demanded by consumers is a very important process that can enhance the completeness of the product through the painting process.

Although this is very important, if a defect occurs or the painting process is insufficient, it is treated as a defect regardless of the performance of the product or the painting process is performed again, thereby increasing the product production cost.

In particular, although it is a painting treatment process that corresponds to one of the main processes that enhances the completeness of the product, the painting process is often carried out manually by highly skilled workers in a non-automated state in general industrial sites.

However, no matter how highly skilled a worker is, the state of painting on the surface of the product can be formed in various ways depending on the working conditions, condition, and skill level of each worker, and even the same worker can have different thicknesses of the product's coating layer depending on the case. there is.

Under these conditions, it is difficult to obtain a uniform coating thickness on the surface of the product, and it is difficult to sufficiently satisfy product completeness and consumer needs.

Therefore, as a method for solving the above-mentioned problems of manual work, Korean Patent Registration No. 10-0378606, Patent Publication No. 10-2004-0110140, and Publication Patent No. 10-2004-0110141 are disclosed.

In the case of the above prior literature, the spray gun is moved according to the set signal values of the X, Y, and Z axes through the linear movement mechanism to coat the surface of the object to be coated in a rectangular shape, the complexity of the overall structure, and product production accordingly It has been somewhat difficult to install and use in the field due to factors such as an increase in cost.

In order to solve these problems and the like, Korean Patent Registration No. 10-1839070, 'painting automation device with improved work efficiency' is disclosed.

In the case of the above prior literature, through structural improvement, the paint spraying operation is performed in conjunction with the rotational motion of the object to be coated during the painting process, so that the paint can be applied evenly to the outer surface of the object to be coated, and the overall structure is simplified It provides a structure that can reduce the installation and manufacturing costs of the device.

In the case of the above prior literature, it can be seen that some of the problems of the prior literature introduced earlier have been solved, but a belt pulley and a belt are employed as a driving means for rotating the fixing pin for fixing the object to be coated, but the belt pulley and The accuracy of the driving force transmitted by the frictional force between the belts decreases in proportion to the use time of the device.

When the drive transmission force is transmitted to the belt in direct proportion, the paint sprayed by the spray gun on the surface of the object to be coated can be painted with a certain thickness.

However, as described above, when the contact force between the belt and the belt pulley decreases in proportion to the use time, a moment in which the rotational force of the fixing pin supporting the object to be coated is minutely stopped occurs, resulting in a uniform surface of the driven object. The problem that coating treatment by application is impossible is unavoidable.

Therefore, as a way to solve the above problems, there is an "automated spray coating device" of Korean Patent Registration No. 10-2295393 proposed by the present applicant.

The patent registered by the applicant described above is a first drive motor connected to the surface of the object to be coated so that the thickness of the coating layer on the surface of the object to be coated can be uniform when spray coating the surface of the object to be coated using a spray gun. 1The driving force transmitted by the timing belt can be accurately transmitted, so that the object rotation jig can be rotated at a uniform speed, so that the paint sprayed from the spray gun can be uniformly applied to the surface of the object to be coated and coated. have an effect

However, in the case of the above-described automated spray coating device of the present applicant, after entering the spray coating process, the process of recovering it is not automated, so the jig holding the object to be coated is inserted into the spray space and then completely coated. There is a problem in that a series of processes of recovering the jig holding the object to be coated must be performed individually by the operator.

By doing so, it provides an automatic spray coating system for a coated body that improves productivity.

To this end, the present invention includes a base 10, a jig part 21 provided on an upper surface of one side of the base 10, and a transfer unit 20 of the coated body transported back and forth, and a jig unit 21 in the transfer unit 20 to be coated. ) or the jig portion 30 for supplying the jig portion 21 equipped with a new object to be coated to the transfer portion 20 side of the object to be coated, and the jig portion from the rotation portion 30 of the object to be coated 21) or a to-be-coated jig supply and discharge unit 40 for supplying a new jig unit 21 to the to-be-coated jig rotating unit 30.

As shown in FIG. 1, the base 10 is provided with a substrate transfer unit 20 on one side of the upper surface and a substrate jig rotation unit 30 on the front side.

In addition, the to-be-coated jig supply and discharge unit 40 is configured to be transportable from the side of the to-be-coated jig rotation unit 30.

The to-be-coated body transfer unit 20 is configured to be transported back and forth on the upper surface of one side of the base 10 described above, and has the same configuration as in FIG. Since the configuration of Korean Patent Registration No. 10-2295393 is borrowed, description of the detailed configuration thereof is partially omitted and only the main components are described.

2 shows such a coated object transfer unit 20, a central support 25 connected upwardly to the transfer table 23, a horizontal frame 26 connected horizontally at the upper end of the central support 25, It has a jig part 21 for fixing each of the objects to be coated to the upper surface of the horizontal frame 26.

Meanwhile, a drive gear wheel 27 and a driven gear wheel 28 provided at both ends of the horizontal frame 26 are positioned, and a drive motor (not shown) for driving the drive gear wheel 27 is provided. A timing belt 29 is provided to transmit the driving force of the driving motor to the jig part 21 to forward and reverse rotate the jigs 22 arranged in the jig part 21 .

Detailed components and operation relationships of the object transfer unit 20 having the above-described components correspond to configurations outside the scope of the technical idea of the present application, so reference can be made to the aforementioned Korean Patent Registration No. 10-2295393. .

The to-be-coated object jig rotation part 30 is the to-be-coated object conveying part 20 that returns after spray coating is completed on the surface of the object to be coated in a spray coating section (not shown) by the transfer of the object-to-be-coated conveying part 20 described above. It is a configuration for extracting the jig part 21 from ), rotating it in the opposite direction, and seating and supplying the newly supplied jig part 21 to the side of the to-be-coated body transfer unit 20 in order to paint the object to be coated. ( see Figure 3)

As shown in FIG. 3, a rotating body 33 connected upward to the fixing plate 34 is provided, and the rotating body 33 is configured to rotate forward and backward by a motor.

The rotation area of the rotating body 33 is rotated by 180°.

The rotating body 33 is provided with suction gripping parts 31 at both ends starting from the center, and the suction gripping parts 31 can be moved forward and backward by the forward and backward transfer LM block 32.

The adsorbing holding part 31 is a means for adsorbing and moving the jig part 21 of the conveying part 20 of the object to be coated.

For example, the jig part 21 provided with the objects to be coated and fixed to the jig 22 arranged in multiple rows toward the spray coating part (not shown) is attached to the object transfer part 20 on one side of the base 10. It is transported in a seated state and moved to the spray coating unit (not shown), and the objects to be coated provided in the jig 22 of the jig unit 21 may be coated by a spray gun.

In this way, the surface of the object to be coated in the spray painting unit has a uniform thickness, and after the painting process is completed, the object transfer unit 20 returns to the original position.

On the other hand, as described above, when the return to the original position of the object transfer unit 20 having the object having been coated has been completed, the object transfer unit 20 is moved by the object jig rotation unit 30. ) adsorbs the jig part 21 and is rotated by 180° to be displaced to the opposite position.

To this end, as described above, the adsorption holding unit 31 can be forward and backward transport along the forward and backward transfer LM block 32, and after adsorbing and gripping the jig unit 21 from the object transfer unit 20, the rotating body ( 33) can be rotated 180° so that it is positioned in the opposite direction.

The provision of adsorption force in the adsorption gripping part 31 may be performed by vacuum adsorption by a known technique or the like, or electromagnetic force or the like may be used.

In the case of using electromagnetic force or the like, of course, a short circuit must be made by turning on/off the electromagnetic force in the suction gripping unit 31 .

On the other hand, after being rotated 180° in the adsorbed state by the suction gripping unit 31, the adjacent coated object jig supply and discharge unit 40 loads and discharges the jig 22 from the suction gripping unit 31. It can be discharged to the guide 46 side.

The above operation described the process of recovering the jig part 21 in which the painted objects are seated in the spray painting unit, but the operation for supplying the objects to be coated also works in the reverse order.

That is, the above-described jig supply and discharge unit 40 for the object to be coated is provided at a position adjacent to the jig rotation unit 30 for the object to be coated.

The to-be-coated jig supply and discharge unit 40 allows the jig unit 21 to be loaded and discharged to the to-be-coated jig rotation unit 30, and the jig unit supporting the unpainted body to be coated ( 21) is a configuration for supplying.

As shown in FIG. 4, the to-be-coated jig supply and discharge unit 40 is connected to the loading port 41 for the jig unit 21 to be seated and the loading port 41 below the loading port 41 to rotate the loading port 41. Forward and reverse rotation unit 42, a transfer block 43 connected to the lower end of the forward and reverse rotation unit 42, a rail 44 for guiding forward and backward transfer of the transfer block 43, and the loading hole ( 41) and a pushing part 45 that pushes from one side to enable discharge of the jig part 21 loaded in the loading port 41 by the pushing of the pushing part 45 ( 21) is composed of a discharge guide 46 for guiding the external discharge.

On the other hand, a supply tray unit 50 is provided to supply the jig unit 21 on which the unpainted body is seated to the side of the jig supply and discharge unit 40 for the object to be coated.

The supply tray unit 50 may be supplied by a conveyor belt or the like.

However, the jig part 21 supplied through the supply tray part 50 should be in a straight line position when the loading port 41 of the jig supply and discharge part 40 is rotated. If not, the jig part 21 supplied from the supply tray part 50 accurately guides the jig supply and discharge part 40 of the object to be coated to match because it is not loaded into the loading port 41, As shown in the drawing, it is preferable that the supply guider 51 is provided in the supply tray unit 50.

Referring to the operating relationship of the present invention having the above configuration with reference to FIGS. 7 to 10, first, the jig part 21 in which the jigs 22 having the objects to be coated for coating and painting treatment are seated on the surface are arranged is supplied. It is supplied through the tray unit 50.

On the upper surface of the front end of the supply tray unit 50, the jig unit 21 can be supplied in a straight position in a straight line, and the transfer block 43 is along the rail 44 on the front end side of the supply tray unit 50. It is transported so that the loading port 41 of the to-be-coated body jig supply and discharge unit 40 is in an adjacent state. In this state, the jig part 21 placed on the front end side of the supply tray part 50 is seated toward the loading port 41 side.

As shown in FIGS. 8 and 9, the loading port 41 in which the jig part 21 is seated is rotated 90° by the rotation of the normal and reverse rotation part 42 and then the transfer block 43 is returned to its original position. The transfer block 43 advances and transfers along the rail 44 to a position adjacent to the omnidirectional direction, that is, the jig rotating part 30 of the object to be coated.

In the above state, the adsorption holding part 31 of the jig rotating part 30 to be coated moves forward and adsorbs the side surface of the jig part 21 as shown in FIG. 9, and then the rotating body 33 By rotating 180°, as shown in FIG. 10, the jig part 21 is seated on the side of the object transfer part 20.

After the jig part 21 is seated on the object conveying part 20, the adsorption force of the adsorption holding part 31 adsorbing the jig part 21 is removed, and then the rotating body 33 is re-rotated to avoid avoidance. It is returned to the original position of the coating jig supply and discharge unit 40.

At this time, the adsorption-holding part 31 on the other side of the adsorption-holding part 31 for seating the jig part 21 from the object-to-be-coated jig rotating part 30 to the side of the object-to-be-coated transfer part 20 supplies the jig of the object to be coated. And it is in a state located on the side of the discharge part 40. As described above, while the jig part 21 is seated on the object transfer part 20, the other suction gripping part 31 moves through the process described above. The process of adsorbing the jig part 21 supplied through the supply tray part 50 and the supply guider 51, that is, the jig part 21 provided with the object to be coated for painting, is performed simultaneously.

Therefore, while the jig rotating part 30 of the object to be coated repeatedly rotates 180°, the adsorption holding part 31 has a jig part having a new object to be coated for painting in the jig supply and discharge unit 40 of the object to be coated. After adsorbing (21), it is loaded to the side of the object transfer unit 20, and then the object transfer unit 20 is transported and undergoes a painting process.

When the coated object transfer unit 20 is transported, coated, and returned to the original position, the adsorption holding unit 31 of the coated body jig rotation unit 30 moves forward and transfers the jig unit 21 having the coated object At the same time, the adsorption holding part 31 on the opposite side is the loading port 41 of the jig supply and discharge part 40 of the jig part 21 supplied from the supply tray part 50 as described above. ), when the transfer block 43 is moved to the side of the jig rotating part 30 to be coated and reaches an adjacent position in the state of being loaded in the jig part 31, the process of gripping the jig part 21 by the forward transfer of the suction gripping part 31 will go through

That is, the to-be-coated jig rotation part 30 is the jig part 21 to be painted through the to-be-coated body transfer part 20 and the jig part to be painted through the jig supply and discharge part 40 in both directions, respectively. (21) is absorbed and held at the same time and then rotated 180° so that the jig part 21 loaded in the loading port 41 to be painted is seated toward the target object transfer unit 20, and the target object transfer unit 20 The painted jig part 21 seated in is loaded into the loading port 41 side of the jig supply and discharge part 40 to be coated and undergoes a position change process.

Through the position change process in this way, the jig part 21 having the coated object is seated in the loading hole 41, and the pushing part 45 of the object jig supply and discharge part 40 ) is operated to have a process of pushing the jig part 21 seated on the loading port 41 toward the discharge guide 46 and discharging it.

Therefore, by repeating the above process, the input and discharge process of the jig part 21 accommodating the objects to be painted and the jig parts 21 accommodating the objects to be coated are fully automated to improve productivity. will be able to
