Abstract

A deburring device and method for a coated part. The deburring device for the coated part is applicable to a part unit after coating, and includes a base unit, a material taking unit, a reciprocating unit, and a restoring unit. The material taking unit is connected to the base unit and is at least used to connect two sides of the part unit spaced apart in the up and down direction. The reciprocating unit is arranged on the material taking unit and includes a moving member that can reciprocate in the up and down direction and a driving group that drives the moving member to reciprocate. The reciprocating unit drives a part group of the part unit to reciprocate in the up and down direction between a first position and a second position.

Description

Technical Field

[0001] The present invention relates to a coating device, and particularly to a device and method for removing burrs after coating. Background Art

[0002] In the general coating process, in order to prevent the object to be coated from shifting during the process, an adhesive material is usually used to fix the object to be coated and the carrier fixture, and then the subsequent coating steps are carried out. However, since there is a continuous film layer between the object to be coated and the adhesive material after coating, when separating the object to be coated from the adhesive material, it is easy to cause an uneven cross-section at the separation position due to the viscosity of the adhesive material itself, that is, coating burrs, or part of the film layer is directly peeled off from the surface of the object to be coated, resulting in the phenomenon of undercoating.

[0003] In order to improve the phenomenon of coating burrs, an existing improvement method is to apply a downward pressure to the object to be coated in advance, and through the elasticity of the adhesive material itself, the object to be coated rebounds upward. Such reciprocating motion up and down can cause the part of the continuous coating layer adjacent to the contact position between the outer peripheral side of at least one object to be coated and the soft adhesive material to be sheared to form a flat cross-section, so that there will be no burrs on the coating layer on the surface of the object to be coated. Therefore, there is no need to perform additional destructive deburring operations, which can greatly improve the yield and reduce the labor, time and equipment costs.

[0004] However, due to the limited elasticity of the adhesive material itself, there may still be a phenomenon of burr residue. Summary of the Invention

[0005] The purpose of the present invention is to provide a device for removing burrs after coating that can more effectively remove burrs.

[0006] Therefore, the device for removing burrs after coating is applicable to a workpiece unit after coating. Each workpiece unit has a fixture, an adhesive material connected to the fixture, a workpiece group removably fixed to the fixture through the adhesive material and arranged in the fixture, and a coating layer plated on the workpiece group. The workpiece group has a plurality of workpieces. The device for removing burrs after coating includes a base unit, a material taking unit, a reciprocating unit, and a restoring unit.

[0007] The material taking unit is connected to the base unit and is at least used to connect the two sides of the workpiece unit at intervals in the up and down direction, and is used to limit the movement of the fixture in the up and down direction.

[0008] The reciprocating unit is disposed on the material taking unit, and includes a moving member that can reciprocate in the vertical direction, and a driving group that drives the moving member to reciprocate. The reciprocating unit drives the material group to reciprocate between a first position and a second position in the vertical direction. When at the first position, the material group is away from the base unit, and when at the second position, the material group is adjacent to the base unit.

[0009] The restoring unit is disposed on the material taking unit and is spaced from the reciprocating unit by a distance in the vertical direction, and always moves the material group towards the second position.

[0010] In the deburring device for coated film of the present invention, the reciprocating unit is located below the restoring unit.

[0011] In the deburring device for coated film of the present invention, the material taking unit includes a reciprocating group connected to the moving member and corresponding to the material group in position. The reciprocating group includes a plurality of reciprocating ejector pins corresponding to the materials respectively. The moving member drives the reciprocating ejector pins to push against and drive each material to reciprocate in the vertical direction.

[0012] In the deburring device for coated film of the present invention, the driving group has a cam contacting the moving member, and a driving member for driving the cam to rotate. The cam has a first wheel portion and a second wheel portion, and the curvature radius of the first wheel portion is greater than the curvature radius of the second wheel portion.

[0013] In the deburring device for coated film of the present invention, when the first wheel portion of the cam contacts the moving member, the material group is at the first position, and when the second wheel portion of the cam contacts the moving member, the material group is at the second position.

[0014] In the deburring device for coated film of the present invention, the material taking unit further includes a restoring group corresponding to the material group in position. Each restoring group includes a plurality of restoring ejector pins corresponding to the materials respectively. The restoring unit includes a plurality of springs respectively connecting the restoring ejector pins, and each spring always makes the corresponding restoring ejector pin drive the corresponding material towards the second position.

[0015] The deburring device for coated film of the present invention further includes a limiting unit. The limiting unit includes a plurality of limiting groups for limiting the movement of the fixture in the vertical direction. Each limiting group includes an upper limiting member, and a lower limiting member spaced from the upper limiting member by a distance in the vertical direction. The upper limiting member is used to contact the adhesive material from top to bottom, and the lower limiting member is used to contact the fixture from bottom to top.

[0016] Another object of the present invention is to provide a method for removing burrs after coating that can more effectively remove burrs.

[0017] Therefore, the method for removing burrs after coating includes the following steps:

[0018] Prepare the burr removal device after coating as described above.

[0019] A plurality of reciprocating ejectors and a plurality of return ejectors of the material taking unit fix the workpiece in the vertical direction.

[0020] The reciprocating unit drives one of the workpiece groups to reciprocate in the vertical direction. During the process, the return unit always moves the workpiece group towards the second position.

[0021] The beneficial effect of the present invention is that: the material taking unit is used to limit the movement of the fixture in the vertical direction, and the reciprocating unit drives the workpiece group to reciprocate in the vertical direction, so that the part of the coating layer adjacent to the contact position between the outer periphery of each workpiece in the workpiece group and the adhesive material forms a flat cross-section. Therefore, after each workpiece is removed from the adhesive material, there will be no burrs on the coating layer of the workpiece. Since the reciprocating unit actively reciprocates in the vertical direction, it is not limited by the elasticity of the adhesive material. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Description of the Invention

[0035] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0036] In addition, a vertical direction X1, a left-right direction X2, and a front-back direction X3 that are perpendicular to each other are defined.

[0037] Referring to Figure 1 and Figure 6 , a first embodiment of the burr removal device after coating of the present invention is applicable to a workpiece unit 7 (see Figure 7 ) after coating. Each workpiece unit 7 has a jig 71, an adhesive 72 connected to the jig 71, a plurality of workpiece groups 73 removably fixed to the jig 71 through the adhesive 72 and arranged in the jig 71, and a coating layer 74 plated on the workpiece groups 73 (see Figure 7 ). Each of the workpiece groups 73 has a plurality of workpieces 731, and at least one part of each workpiece 731 is connected to the jig 71. The workpieces 731 of each workpiece group 73 are arranged in an extension along the left-right direction X1, and the workpiece groups 73 are arranged at intervals along the front-back direction X2.

[0038] The jig 71 is positioned at the picking unit 2 described later.

[0039] In this embodiment, the fixture 71 has a plurality of through holes 711 extending along the X1 direction, and the through holes 711 are arranged in a matrix. The component group 73 is adhered to the fixture 71 by an adhesive 72. The adhesive 72 is a double-sided tape, and its two sides are respectively adhered to the fixture 71 and the component group 73. Each component 731 is placed above each through hole 711, and the area of each component 731 observed from top to bottom is larger than the area of the corresponding through hole 711. That is to say, the outer edge of each component 731 is fixed within the fixture 71 through the adhesive 72.

[0040] Refer to Figure 1 、 Figure 2 and Figure 7 , the burr removal device after coating includes a base unit 1, a material taking unit 2, a reciprocating unit 3, a restoring unit 4 and a conveying unit 5.

[0041] The base unit 1 has a frame 11 standing on the ground and a table board 12 connected to the frame 11.

[0042] Refer to Figures 2 - 5 , the material taking unit 2 is connected to the table board 12 and includes a reciprocating group 21 extending along the up and down direction X1 and corresponding to the component group 73, a restoring group 22 extending along the up and down direction X1 and corresponding to the component group 73, and a moving group 23 driving the reciprocating group 21 and the restoring group 22 to move along the up and down direction X1.

[0043] The reciprocating group 21 is located below the restoring group 22 and includes a plurality of reciprocating ejector pins 211 corresponding to the components 731 respectively. Each reciprocating ejector pin 211 passes through the corresponding through hole 711 to contact the corresponding component 731.

[0044] The restoring group 22 is located above the table board 12.

[0045] Each restoring group 22 includes a plurality of restoring ejector pins 221 corresponding to the components 731 respectively.

[0046] The moving group 23 includes two slide rails 231 and two sliders 232 movably arranged on the slide rails 231 respectively. One of the sliders 232 is connected to the reciprocating group 21, and the other slider 232 is connected to the restoring group 22.

[0047] Refer to Figure 6 and Figure 7, the reciprocating unit 3 is disposed above the table board 12 and connected to the reciprocating group 21 of the material taking unit 2, and includes a moving member 31 that can reciprocate along the up and down direction X1, and a driving group 32 that drives the moving member 31 to reciprocate. The moving member 31 drives the reciprocating ejector pin 211 to push against and drive each workpiece 731 to reciprocate along the up and down direction X1.

[0048] The driving group 32 has a cam 321 in contact with the moving member 31, and a driving member 322 that drives the cam 321 to rotate. The cam 321 has a first wheel portion 323 and a second wheel portion 324 connected to the first wheel portion 323. The radius of curvature of the first wheel portion 323 is greater than the radius of curvature of the second wheel portion 324.

[0049] Further explanation is that the first wheel portion 323 is the part including the farthest point from the center point of the cam 321 on the circumference of the cam 321, and the second wheel portion 324 is the part including the closest point to the center point of the cam 321 on the circumference of the cam 321.

[0050] Refer to Figure 7 、 Figure 8 And Figure 9 , the reciprocating unit 3 drives the workpiece group 73 to reciprocate along the up and down direction X1 between a first position ( Figure 7 ) and a second position ( Figure 8 、 Figure 9 ). When at the first position, the workpiece group 73 is away from the base unit 1, and the first wheel portion 323 of the cam 321 contacts the moving member 31. When at the second position, the workpiece group 73 is adjacent to the base unit 1, and the second wheel portion 324 of the cam 321 contacts the moving member 31.

[0051] The restoring unit 4 is disposed above the table board 12 and connected to the restoring group 22 of the material taking unit 2 and is spaced apart from the reciprocating unit 3 by a distance along the up and down direction X1. The restoring unit 4 includes a plurality of springs 41 respectively connected to the restoring ejector pins 221, and each spring 41 always makes the corresponding restoring ejector pin 221 drive the corresponding workpiece 731 to move toward the second position.

[0052] Refer to Figure 7 And Figure 8 , when the workpiece group 73 is at the first position ( Figure 7 ), the cam 321 contacts the moving member 31 with the first wheel portion 323, so that the moving member 31 drives the reciprocating group 21 to move upward and drives the workpiece group 73 to move upward to the second position ( Figure 8) and the component group 73 compresses the return ejector pin 221 of the return group 22, thereby compressing the spring 41 ( Figure 8 ), storing elastic potential energy. When the cam 321 rotates to make the cam 321 contact the moving member 31 with the second wheel portion 324, the moving member 31 drives the reciprocating group 21 to move downward, and the return group 22 moves downward under the restoring force of the elastic potential energy released by the spring 41 and its own gravity.

[0053] It should be noted that in other variant embodiments of the present embodiment, the positions of the reciprocating unit 3 and the return unit 4 can be interchanged at an angle, that is, the reciprocating unit 3 is connected to the return group 22, and the return unit 4 is connected to the reciprocating group 21.

[0054] See Figure 2 、 Figure 6 、 Figure 7 And Figure 10 , the conveying unit 5 is used to convey the component unit 7 without deburring to the picking unit 2, or convey the component unit 7 with deburring out of the picking unit 2, and sequentially convey each component group 73 on the component unit 7 to the picking unit 2.

[0055] Further, the conveying unit 5 conveys each component group 73 to the position corresponding to the picking unit 2, and the reciprocating unit 3 and the return group 22 process one component group 73 each time as Figure 10 shown. After the burrs of the component group 73 are removed, the conveying unit 5 will convey the next component group 73 to the position corresponding to the picking unit 2 to continue the burr removal operation.

[0056] The method for removing burrs after coating using the foregoing device includes the following steps:

[0057] 1. Convey the component unit 7 without deburring to the picking unit 2.

[0058] 2. Through the moving group 23, the reciprocating ejector pin 211 and the return ejector pin 221 of the picking unit 2 fix the jig 71 along the up and down direction X1.

[0059] 3. The reciprocating unit 3 drives one of the component groups 73 to reciprocate along the up and down direction X1. During the process, the return unit 4 always makes the component group 73 move toward the second position.

[0060] Make the part of the coating layer 74 adjacent to the contact position between the outer peripheral side of each component 731 of the component group 73 and the adhesive 72 form a flat cross-section.

[0061] 4. The conveying unit 5 transports the next workpiece group 73 to the position corresponding to the picking unit 2.

[0062] 5. Repeat steps 2, 3, and 4 until deburring (steps 2 and 3) is completed for each workpiece group 73 on the workpiece unit 7.

[0063] Through the above description, the advantages of the foregoing embodiments can be summarized as follows:

[0064] 1. By using the picking unit 2 to restrict the movement of the fixture 71 in the up and down direction X1, and the reciprocating unit 3 driving the workpiece group 73 to reciprocate in the up and down direction X1, a flat cross-section is formed at the part where the coating layer 74 adjacent to the outer peripheral side of each workpiece 731 in the workpiece group 73 contacts the adhesive 72. Therefore, after each workpiece 731 is removed from the adhesive 72, there will be no burrs on the coating layer 74 of the workpiece 731. Since the reciprocating unit 3 actively drives the workpiece group 73 to reciprocate in the up and down direction X1, it is not limited by the elasticity of the adhesive 72.

[0065] 2. In addition, a restoring force is provided by the restoring group 22, enabling the workpiece group 73 to move more easily towards the second position.

[0066] 3. In addition to the above, since in this embodiment, the restoring unit 4 is located above the reciprocating unit 3, when the workpiece group 73 moves downward towards the second position, in addition to the driving of the reciprocating group 21 and the restoring force of the spring 41, it can also move downward by its own gravity.

[0067] Refer to Figures 11 - 14 , which is the second embodiment of the burr removal device for the coated workpiece of the present invention, and is also applicable to the workpiece unit 7 after coating. The difference lies only in: the form of the workpiece unit 7, and the second embodiment further includes a limiting unit 6.

[0068] The fixture 71 includes a continuous surface and does not have holes as in the previous embodiment. The adhesive 72 is a single-sided adhesive, and the sticky surface is adhered to the workpiece group 73.

[0069] It is worth noting that the fixture 71 can be rectangular or circular, as long as the workpieces 731 are arranged in a matrix form (the number of rows and columns does not have to be the same).

[0070] The limiting unit 6 includes a plurality of limiting groups 60 for limiting the movement of the jig 71 in the up and down direction X1. Each limiting group 60 includes an upper limiting member 61 and a lower limiting member 62 spaced from the upper limiting member 61 by a distance in the up and down direction X1. The upper limiting member 61 is used to contact the adhesive 72 from top to bottom, and the lower limiting member 62 is used to contact the jig 71 from bottom to top.

[0071] In this way, by limiting the movement of the jig 71 in the up and down direction by the limiting unit 6, and then driving the workpiece group 73 to reciprocate in the up and down direction X1 by the reciprocating unit 3, the effects of the foregoing embodiments can be achieved.

[0072] In addition to achieving the effects of the foregoing embodiments, this embodiment also exemplifies different processing methods for the workpiece unit 7.

[0073] The above are only the embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still fall within the scope of the present invention.
