Description

Technical Field

[0001] The present invention relates to the technical field of hangers, and in particular to a hanger trimming method and a hanger trimming device. Background Art

[0002] In the prior art, a hanger is generally used as a carrier for the electroplating of products. The hanger is generally provided with a hanger, and the product can be fixed on the hanger so that it can be placed in the electroplating tank for electroplating. Specifically, the hanger includes two rods arranged opposite to each other, and both ends of the two rods are provided with spring plates. The spring plates at the same end of the two rods are arranged opposite to each other, and the product can be clamped between the two spring plates arranged opposite to each other.

[0003] In order to enable electroplating of products, anode points are formed on the springs, which enable redox reactions on the surface of the products to form a coating on the surface of the products. However, during the electroplating process, the surface of the springs will also undergo redox reactions, forming an oxide layer on the surface of the springs. In order to enable the hanger to continuously mount products for electroplating, the surface of the springs needs to be polished between two electroplating operations to remove the oxide layer. At the same time, during the use of the hanger, the rods and / or springs on the hanger may be deformed due to external forces, etc., resulting in the hanger being unable to stably and effectively mount the product, and thus the product being unable to be effectively electroplated. Therefore, between two electroplating operations, the deformed hanger needs to be reshaped to ensure that the subsequent electroplating operation can be carried out effectively.

[0004] In the prior art, hangers are generally polished and shaped by manual trimming. However, manual trimming has low stability and is prone to damage to the hanger. In addition, the force of manual shaping cannot be accurately controlled during manual operation, resulting in poor consistency in the shapes of the two rods of the hanger and the spring pieces on the rods after shaping.

[0050] like Figure 2 As shown, the hanger 100 for mounting products includes a mounting frame 120 and multiple hangers 110, each hanger 110 includes a first rod 111 and a second rod 112 arranged opposite to each other, the first rod 111 and the second rod 112 are fixedly connected to the mounting frame 120, both ends of the first rod 111 are provided with a first spring piece 1111, both ends of the second rod 112 are provided with a second spring piece 1121, the first spring piece 1111 and the second spring piece 1121 are arranged opposite to each other, the product can be clamped between the first spring piece 1111 and the second spring piece 1121, and anode points are formed on the opposite sides of the first spring piece 1111 and the second spring piece 1121.

[0051] During the electroplating process, the opposite side of the first spring piece 1111 and the second spring piece 1121 will also undergo an oxidation-reduction reaction, thereby forming an oxide layer on the opposite side of the first spring piece 1111 and the second spring piece 1121. In order to enable the hanger 100 to continuously mount products for electroplating, it is necessary to polish the opposite side of the first spring piece 1111 and the second spring piece 1121 between two electroplating operations to remove the oxide layer. At the same time, during the use of the hanger 100, the first rod 111 and / or the second rod 112 and / or the first spring piece 1111 and / or the second spring piece 1121 may be deformed due to external forces, etc. Specifically, the end of the first rod 111 and / or the end of the second rod 112 may be deformed along the first rod 111 and the second rod 112 due to external forces, etc. 1111 and the second spring piece 1121 are deflected in a direction perpendicular to the arrangement direction of the first rod 111 and the second rod 112. In addition, the side of the first spring piece 1111 facing the second spring piece 1121 may be deflected toward or away from the second spring piece 1121 due to external forces, etc. Correspondingly, the side of the second spring piece 1121 facing the first spring piece 1111 may also be deflected toward or away from the first spring piece 1111 due to external forces, etc., resulting in the side of the first spring piece 1111 facing the second spring piece 1121 not being opposite to the side of the second spring piece 1121 facing the first spring piece 1111, thereby causing the hanger 100 to be unable to stably and effectively mount the product, thereby causing the product to be unable to be effectively electroplated.

[0052] To trim the rack 110 on the hanger 100 mentioned above, please refer to Figure 1 , and combined with Figures 2 to 5 This embodiment provides a hanger trimming method, which includes:

[0053] Fix the hanger 100 on the fixture 210;

[0054] The manipulator 220 moves the grinding head 221 to grind the opposite side of the first elastic piece 1111 and the second elastic piece 1121 .

[0055] That is, in this embodiment, the surface of the anode point formed by the first spring piece 1111 and the second spring piece 1121 is polished by moving the grinding head 221 by the robot 220, so as to remove the oxide layer formed on the surface of the anode point formed by the first spring piece 1111 and the second spring piece 1121.

[0056] In addition to the above steps, the hanger trimming method in this embodiment also includes:

[0057] The first rod 111 or the second rod 112 is clamped by the parallel first clamping finger 2311 and the second clamping finger 2312, and the axial directions of the first clamping finger 2311 and the second clamping finger 2312 are kept parallel to the arrangement direction of the first rod 111 and the second rod 112, so that the second clamping finger 2312 rotates around the axis of the first clamping finger 2311 to twist the first rod 111 or the second rod 112.

[0058] That is, in this embodiment, the first clamping finger 2311 and the second clamping finger 2312 are used to reshape the first rod 111 and / or the second rod 112 in a direction perpendicular to the arrangement direction of the first rod 111 and the second rod 112, thereby correcting the deviation of the first elastic piece 1111 and / or the second elastic piece 1121 in the direction perpendicular to the arrangement direction of the first rod 111 and the second rod 112. Specifically, the first clamping finger 2311 and the second clamping finger 2312 are respectively in contact with two sides of the first rod 111 or the second rod 112, wherein the second clamping finger 2312 rotates clockwise or counterclockwise around the axis of the first clamping finger 2311, thereby correcting the first rod 111 or the second rod 112.

[0059] In addition to the above steps, the hanger trimming method in this embodiment also includes:

[0060] By symmetrically setting the first pressing block 2321 and the second pressing block 2322, respectively pressing the side of the first elastic piece 1111 toward and away from the second elastic piece 1121, or respectively pressing the side of the second elastic piece 1121 toward and away from the first elastic piece 1111, the first pressing block 2321 and the second pressing block 2322 are rotated around their symmetry axis to twist the first elastic piece 1111 or the second elastic piece 1121.

[0061] That is, in this embodiment, the first spring piece 1111 and / or the second spring piece 1121 are shaped by the first pressing block 2321 and the second pressing block 2322, thereby correcting the deflection of the first spring piece 1111 and / or the second spring piece 1121, so that the side of the first spring piece 1111 facing the second spring piece 1121 is opposite to the side of the second spring piece 1121 facing the first spring piece 1111. Specifically, the first pressing block 2321 and the second pressing block 2322 can respectively press the side of the first spring piece 1111 facing and away from the second spring piece 1121 or the side of the second spring piece 1121 facing and away from the first spring piece 1111, and the first pressing block 2321 and the second pressing block 2322 can rotate clockwise or counterclockwise around their axes of symmetry, thereby correcting the first spring piece 1111 or the second spring piece 1121.

[0062] Based on the above, this embodiment uses the robot 220 to move the grinding head 221 to grind the surface of the anode point of the first spring piece 1111 and the second spring piece 1121, and uses the first clamping finger 2311 and the second clamping finger 2312 to shape the first rod 111 and / or the second rod 112 in a direction perpendicular to the arrangement direction of the first rod 111 and the second rod 112. Moreover, this embodiment also uses the first pressing block 2321 and the second pressing block 2322 to shape the first spring piece 1111 and / or the second spring piece 1121, thereby realizing automatic trimming of the hanger 100. The entire trimming process has high stability and is not easy to damage the hanger 100. The automatic trimming can accurately control the shaping force, thereby ensuring that the shapes of the first rod 111 and the second rod 112 and the first spring piece 1111 and the second spring piece 1121 after shaping are highly consistent. Moreover, the efficiency of the automatic trimming is high.

[0063] like Figures 3 to 7 As shown, this embodiment also provides a hanger trimming device, which trims the hanger 100 based on the above-mentioned hanger trimming method. The hanger trimming device includes a jig 210, a manipulator 220 and a shaping mechanism 230. The jig 210 is configured to carry the hanger 100. A grinding head 221 is installed at the end of the manipulator 220. The manipulator 220 is configured to move the grinding head 221 so that the grinding head 221 can grind the surface of the first spring piece 1111 and the second spring piece 1121 to form an anode point. The shaping mechanism 230 includes a first clamping finger 2311, a second clamping finger 2312, a first pressure block 2321 and a second pressure block 2322. The first clamping finger 2311 and the second clamping finger 2312 are arranged in parallel, and the first pressure block 2321 and the second pressure block 2322 are arranged symmetrically.

[0064] In addition to the fixture 210, the manipulator 220 and the shaping mechanism 230, the hanger dressing device also includes a first driving mechanism 240 and a second driving mechanism 250, wherein the first driving mechanism 240 includes a first driving member 241 and a second driving member 242, and the first driving member 241 can drive the first clamping finger 2311 and the second clamping finger 2312 to move to the first rod 111 or the second rod 112, so that the first clamping finger 2311 and the second clamping finger 2312 can clamp one end of the first rod 111 or the second rod 112, and the second driving member 242 can drive the second clamping finger 2312 to rotate around the axis of the first clamping finger 2311, that is, the first driving mechanism 240 can drive the first clamping finger 2311 and the second clamping finger 2312 to move together, and can drive the second clamping finger 2312 to rotate around the axis of the first clamping finger 2311, thereby adjusting the first rod 111 and / or The second rod 112 is shaped in a direction perpendicular to the arrangement direction of the first rod 111 and the second rod 112. The second driving mechanism 250 includes a third driving member and a fourth driving member 252. The third driving member can drive the first pressing block 2321 and the second pressing block 2322 to move to the first elastic piece 1111 or the second elastic piece 1121, so that the first pressing block 2321 and the second pressing block 2322 can clamp the first elastic piece 1111 or the second elastic piece 1121. The fourth driving member 252 can drive the first pressing block 2321 and the second pressing block 2322 to rotate around their axis of symmetry. That is, the second driving mechanism 250 can drive the first pressing block 2321 and the second pressing block 2322 to move together, and can drive the first pressing block 2321 and the second pressing block 2322 to rotate around their axis of symmetry, thereby shaping the first elastic piece 1111 and / or the second elastic piece 1121.

[0065] Based on the above, the hanger trimming device in this embodiment can automatically trim the hanger 100. The entire trimming process is highly stable and is not easy to damage the hanger 100. The automated trimming can accurately control the shaping force, thereby ensuring that the shapes of the first rod 111 and the second rod 112 and the first spring piece 1111 and the second spring piece 1121 after shaping are highly consistent. Moreover, the efficiency of automated trimming is high.

[0066] like Figure 4As shown, the jig 210 includes a support block 211, a positioning module 212 and a pressing module 213. The mounting bracket 120 can be placed on the support block 211. The positioning module 212 includes a first positioning block 2121 and a second positioning block 2122 arranged relatively to each other. The first positioning block 2121 and the second positioning block 2122 are respectively provided with a first positioning groove 21211 and a second positioning groove 21221. The mounting bracket 120 can be respectively accommodated in the first positioning groove 21211 and the second positioning groove 21221 on both sides along a direction perpendicular to the arrangement direction of the multiple hangers 110, thereby positioning the hanger 100. The pressing module 213 includes a pressing block 2131 and a fifth driving member 2132. The fifth driving member 2132 can drive the pressing block 2131 to move toward the support block 211 so that the pressing block 2131 can press the mounting bracket 120 to the support block 211, thereby fixing the hanger 100 to the jig 210.

[0067] It is understandable that the fifth driving member 2132 may be a driving structure such as a pneumatic cylinder or an electric cylinder, and this is not specifically limited in this embodiment.

[0068] See also Figure 3 and Figure 5 The first clamping finger 2311 and the second clamping finger 2312 constitute the first shaping assembly 231. To simultaneously shape both ends of the first rod 111 or the second rod 112, two first shaping assemblies 231 are provided in this embodiment, and the two first shaping assemblies 231 are arranged opposite each other. The first pressing block 2321 and the second pressing block 2322 constitute the second shaping assembly 232. Since the first rod 111 is provided with a first spring piece 1111 at both ends, and the second rod 112 is provided with a second spring piece 1121 at both ends, to simultaneously shape both first spring pieces 1111 or both second spring pieces 1121, two second shaping assemblies 232 are provided in this embodiment, and the two second shaping assemblies 232 are arranged opposite each other. All first shaping assemblies 231 are correspondingly provided with a first driving mechanism 240, and all second shaping assemblies 232 are correspondingly provided with a second driving mechanism 250.

[0069] In this embodiment, when the hanger 100 is placed on the jig 210, the axial directions of the first clamping finger 2311 and the second clamping finger 2312 are parallel to the arrangement direction of the first rod 111 and the second rod 112. Specifically, the hanger 100 can be placed horizontally on the jig 210. That is, when the hanger 100 is fixed on the jig 210, the first elastic piece 1111 and the second elastic piece 1121 are opposite to each other in the vertical direction, and the first clamping finger 2311 and the second clamping finger 2312 are located above the hanger 100. Accordingly, in this embodiment, the first driving member 241 can drive the first clamping finger 2311 and the second clamping finger 2312 to move in the vertical direction, so that the first clamping finger 2311 and the second clamping finger 2312 can clamp the first rod 111 located above. The first pressure block 2321 and the second pressure block 2322 are located on the side of the hanger 100, and the first pressure block 2321 is located above the second pressure block 2322. The third driving member includes a first driving part 2511 and a second driving part 2512, wherein the first driving part 2511 is used to drive the first pressure block 2321 and the second pressure block 2322 to move in the horizontal direction, and the second driving part 2512 is used to drive the first pressure block 2321 and the second pressure block 2322 to move in the vertical direction, so that the first pressure block 2321 can press against the upper surface of the first spring piece 1111 located above, and the second pressure block 2322 can press against the lower surface of the first spring piece 1111.

[0070] In order to enable the first clamping finger 2311 and the second clamping finger 2312 to also correct the second rod 112, and the first pressure block 2321 and the second pressure block 2322 to also correct the second spring piece 1121, in this embodiment, after twisting the first rod 111 and / or the first spring piece 1111, the jig 210 is flipped over so that the second rod 112 and the second spring piece 1121 are located at the top, the first clamping finger 2311 and the second clamping finger 2312 can clamp the second rod 112 located at the top, the first pressure block 2321 can press the upper surface of the second spring piece 1121 located at the top, and the second pressure block 2322 can press the lower surface of the second spring piece 1121.

[0071] It should be noted that before flipping the jig 210, the first driving member 241 drives the first clamping finger 2311 and the second clamping finger 2312 away from the hanger 100 in the vertical direction, and the first driving part 2511 drives the first pressing block 2321 and the second pressing block 2322 away from the hanger 100 to avoid interfering with the flipping of the jig 210.

[0072] It can be understood that the first driving member 241, the first driving part 2511 and the second driving part 2512 can all be selected as driving structures such as cylinders or electric cylinders, while the second driving member 242 and the fourth driving member 252 can both be selected as driving structures such as stepping motors or servo motors. There is no specific limitation on this in this embodiment.

[0073] Based on the above, the two second shaping components 232 are respectively arranged corresponding to the two ends of the first rod 111 and the second rod 112. It should be noted that for the second shaping component 232 and one end of the corresponding first rod 111 and the second rod 112, the symmetry axis of the first pressure block 2321 and the second pressure block 2322 is parallel to the extension direction of the part of the first rod 111 and the second rod 112 close to the end, thereby ensuring that when the first pressure block 2321 and the second pressure block 2322 rotate around their symmetry axis, the first elastic piece 1111 can accurately rotate toward or away from the second elastic piece 1121 without rotating in other directions, or the second elastic piece 1121 can accurately rotate toward or away from the first elastic piece 1111 without rotating in other directions.

[0074] It can be understood that the first driving portion 2511 is used to drive the first pressing block 2321 and the second pressing block 2322 to move along the extension direction of their symmetry axes.

[0075] like Figure 3 As shown, the hanger trimming device in this embodiment further includes a third drive mechanism 260, which is configured to flip the jig 210. The third drive mechanism 260 includes a sixth drive member 261 and a mounting plate 262. The jig 210 is fixedly connected to the mounting plate 262, and the sixth drive member 261 is used to drive the mounting plate 262 to flip.

[0076] It is understandable that the sixth driving member 261 may be a driving structure such as a stepping motor or a servo motor, and this is not specifically limited in this embodiment.

[0077] Furthermore, the hanger repair method further includes:

[0078] The robot 220 moves the grinding head 221 to the sandpaper sticking station and sticks sandpaper on the grinding surface of the grinding head 221;

[0079] The robot 220 moves the grinding head 221 to the sandpaper tearing station to tear off the sandpaper on the grinding head 221.

[0080] That is, in this embodiment, sandpaper can be bonded to the end of the grinding head 221, so that the sandpaper can be used to grind the opposite sides of the first spring piece 1111 and the second spring piece 1121 to remove the oxide layer formed on the surface of the anode point formed by the first spring piece 1111 and the second spring piece 1121, thereby improving the grinding quality.

[0081] Specifically, before grinding the first spring piece 1111 and / or the second spring piece 1121 on the hanger 110, the robot 220 moves the grinding head 221 to the sandpaper sticking station to attach sandpaper. After grinding the first spring piece 1111 and / or the second spring piece 1121 on the hanger 110, the robot 220 moves the grinding head 221 to the sandpaper tearing station to tear off the sandpaper, so that the sandpaper can be replaced during the next grinding.

[0082] like Figure 3 and Figure 6 As shown, in this embodiment, the sandpaper on the material strip is torn off by the first film tearing mechanism 271, and the torn sandpaper falls on the carrier 2712 with the adhesive surface of the sandpaper facing upward. At the same time, the robot 220 moves the grinding head 221 and aligns the grinding surface of the grinding head 221 with the adhesive surface of the torn sandpaper. The robot 220 drives the grinding head 221 to move toward the torn sandpaper to attach the torn sandpaper to the grinding head 221. That is, in this embodiment, the sandpaper is attached to the grinding head 221 by automatically attaching the sandpaper, which is more efficient.

[0083] Furthermore, if Figure 3 and Figure 7 As shown, a first clamping plate 2721 is provided at the sandpaper tearing station. After the first elastic piece 1111 and / or the second elastic piece 1121 on the hanger 110 are polished, the manipulator 220 moves the grinding head 221 and inserts the first clamping plate 2721 provided at the sandpaper tearing station between the grinding head 221 and the sandpaper. The sandpaper is clamped by the second clamping plate 2722 and the first clamping plate 2721. Afterwards, the manipulator 220 moves the grinding head 221 and moves the grinding head 221 away from the first clamping plate 2721, thereby tearing the sandpaper off the grinding head 221. That is, in this embodiment, the sandpaper is torn off the grinding head 221 by automatically tearing the sandpaper, which is more efficient.

[0084] Based on the above, and combined with Figure 3 、 Figure 6 and Figure 7The hanger trimming device in this embodiment further includes a first film tearing mechanism 271 and a second film tearing mechanism 272, wherein the first film tearing mechanism 271 includes a film tearing plate 2711, and the film tearing plate 2711 is provided with a tip 27111. The material strip with sandpaper can pass through the tip 27111, thereby tearing the sandpaper from the material strip, and the torn sandpaper can fall onto the carrier 2712. The second film tearing mechanism 272 includes a first clamping plate 2721 and a second clamping plate 2722. The first clamping plate 2721 can be inserted between the grinding head 221 and the sandpaper. Specifically, the manipulator 220 can drive the grinding head 221 toward Move toward the first clamping plate 2721 so that the first clamping plate 2721 can be inserted between the grinding head 221 and the sandpaper, and the second clamping plate 2722 can move toward or away from the first clamping plate 2721, that is, the second film tearing mechanism 272 also includes a seventh driving member 2723, and the seventh driving member 2723 is used to drive the second clamping plate 2722 to move toward or away from the first clamping plate 2721, so that the sandpaper is clamped between the first clamping plate 2721 and the second clamping plate 2722. Afterwards, the manipulator 220 can drive the grinding head 221 away from the second film tearing mechanism 272, so that the sandpaper is torn off the grinding head 221.

[0085] It is understandable that the seventh driving member 2723 can be selected as a driving structure such as a cylinder or an electric cylinder, and there is no specific limitation on this in this embodiment.

[0086] It should be noted that the first film tearing mechanism 271 also includes other structures such as a unwinding reel (not shown in the figure), a rewinding reel (not shown in the figure) and a tensioning wheel (not shown in the figure). Since the specific structure and working principle of the first film tearing mechanism 271 are all existing technologies, they will not be elaborated in this embodiment.

[0087] See also Figure 5 The hanger trimming device in this embodiment further includes a visual detection mechanism 280, which is configured to obtain an image of the hanger 100. Specifically, two visual detection mechanisms 280 are provided in this embodiment. The two visual detection mechanisms 280 are arranged opposite to each other and are respectively used to obtain images of both ends of the hanger 110, so as to respectively obtain images of both ends of the first rod 111 and the second rod 112, so as to respectively detect the deflection degree of both ends of the first rod 111 and the second rod 112, and to detect the deflection degree of the first elastic clip 1111 and the second elastic clip 1121 set on the same side and the thickness of the oxide layer on the first elastic clip 1111 and the second elastic clip 1121 set on the same side.

[0088] Based on the above, the hanger trimming method in this embodiment further includes:

[0089] The images of the first rod 111 , the second rod 112 , the first elastic piece 1111 , and the second elastic piece 1121 are acquired by the visual detection mechanism 280 .

[0090] That is, in this embodiment, the visual inspection mechanism 280 can be used to determine the thickness of the oxide layer that needs to be polished on the first spring piece 1111 and / or the second spring piece 1121, and can determine the degree to which the first rod 111 and / or the second rod 112 needs to be twisted. At the same time, the degree to which the first spring piece 1111 and / or the second spring piece 1121 needs to be twisted can also be determined, so that the manipulator 220 and the shaping mechanism 230 can be further accurately controlled to trim the hanger 100, so as to further ensure that the shapes of the first rod 111 and the second rod 112 and the first spring piece 1111 and the second spring piece 1121 after shaping are highly consistent.

[0091] It is understandable that the specific structure and working principle of the visual detection mechanism 280 are all existing technologies, so they will not be described in detail in this embodiment.

[0092] See also Figure 3 The hanger trimming device in this embodiment also includes a base frame 290, and the third driving mechanism 260 is installed on the base frame 290. The base frame 290 is provided with a slide rail 291. When the hanger 100 is carried on the fixture 210, multiple hangers 110 are arranged along the extension direction of the slide rail 291. The shaping mechanism 230 and the visual inspection mechanism 280 can both move along the slide rail 291, thereby trimming multiple hangers 110 in turn.
