Description

Technical Field

[0001] This application relates to the field of electroplating technology, and in particular to an electroplating suspension bracket. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics.

[0003] During electroplating, an electroplating suspension rack is required to suspend the workpiece to be electroplated on the rack. Then, a lifting device is used to lower the electroplating suspension rack until the workpiece is submerged in the electroplating tank. After electroplating is completed, the electroplating suspension rack is raised until the workpiece is removed from the electroplating tank.

[0004] However, the hook positions on conventional electroplating hangers are usually fixed, while the sizes of the workpieces to be plated vary. After the workpieces are suspended on the hooks, different workpieces will come into contact with each other. The contacting parts cannot fully contact the electroplating solution, resulting in uneven electroplating at the contacting parts of the workpieces, reducing the quality of the plating layer and causing obvious defects. Utility Model Content

[0005] In order to improve the coating quality of the workpiece to be plated, this application provides an electroplating suspension rack.

[0006] The electroplating suspension bracket provided in this application adopts the following technical solution:

[0007] An electroplating suspension rack includes a support frame with multiple connecting plates. Each connecting plate has connecting blocks on opposite sides. Each connecting block has a hook for suspending the plated part. A screw corresponding to each of the multiple connecting plates is rotatably connected to the support frame. The length direction of the screws is perpendicular to the length direction of the connecting plates. The screws are threaded into and slide through the corresponding connecting plates. A first motor corresponding to each of the screws is mounted on the support frame to drive the corresponding screw to rotate.

[0008] By adopting the above technical solution, the worker first places the workpiece to be plated on the hook. When the workpieces come into contact with each other, the worker starts different first motors to control the corresponding screws to rotate. The rotation of the screws drives the corresponding connecting plates to move left and right along the length of the screws, thereby adjusting the spacing between multiple connecting plates. When the connecting plates are adjusted so that the workpieces between adjacent connecting plates no longer come into contact with each other, the galvanizing operation is carried out through the lifting device. This setup achieves the adjustment of the hook position, avoids the workpieces from coming into contact with each other, and ensures that the outer surface of the workpiece can fully contact the electroplating solution, improving the uniformity of the workpiece coating and thus improving the coating quality of the workpiece to be plated.

[0009] Optionally, each of the connecting plates is provided with a sliding groove, and a bidirectional lead screw is rotatably connected in the sliding groove. Two connecting blocks are respectively threaded to two sections of the bidirectional lead screw with opposite thread directions. The connecting blocks are slidably connected in the sliding groove, and a drive assembly for driving the bidirectional lead screw to rotate is provided in the sliding groove.

[0010] By adopting the above technical solution, when the plated parts on the same connecting plate come into contact with each other, the worker drives the bidirectional lead screw to rotate through the drive assembly. The rotation of the bidirectional lead screw causes the two connecting blocks to move towards or away from each other in the sliding groove. The movement of the connecting blocks causes the hook to move, thereby adjusting the distance between the plated parts on the same connecting plate and avoiding the plated parts on the same connecting plate from coming into contact with each other, thereby further improving the coating quality of the workpiece to be plated.

[0011] Optionally, the drive assembly includes a second motor mounted on the connecting plate, the output shaft of the second motor being provided with a worm gear, and the end of the bidirectional lead screw being coaxially and fixedly connected to a worm wheel that meshes with the worm gear, the worm wheel and the worm gear being rotatably disposed within the sliding groove.

[0012] By adopting the above technical solution, when adjustment is required, the second motor is started, which drives the worm to rotate. The worm drives the meshing worm wheel to rotate, and the rotation of the worm wheel drives the bidirectional lead screw to rotate in the sliding groove, thereby realizing the movement of the two connecting blocks in the sliding groove. At the same time, the self-locking characteristics of the worm wheel and worm are used to prevent the bidirectional lead screw from rotating unexpectedly during the electroplating process, which would cause the hook position to change. This reduces quality problems such as plating defects caused by changes in the hook position, thereby further improving the plating quality of the workpiece to be plated.

[0013] Optionally, the hook can be detachably connected to the connecting block via a connecting assembly.

[0014] By adopting the above technical solution, the hook may be damaged or its conductivity may be reduced under long-term operation, which will affect the transfer of electroplating current to the workpiece to be plated, thus affecting the electroplating effect of the workpiece. Therefore, the hook can be detachably connected to the connecting block by the connecting component, which makes it convenient for operators to replace the hook.

[0015] Optionally, the connecting block has a fixing groove, the connecting assembly includes a fixing block that is slidably connected in the fixing groove, the hook is disposed on the fixing block, the fixing block and the connecting block have interconnected pin holes, a pin rod is slidably connected in the pin hole, and a locking nut is threaded to both opposite ends of the pin rod.

[0016] By adopting the above technical solution, when disassembling the hook, the worker rotates the locking nut to disengage it from the pin rod, then pulls the pin rod out of the pin hole, and finally pulls the fixing block out of the fixing mechanism, thus completing the hook disassembly. When installing the hook, the worker slides the fixing block on the hook into the fixing groove, ensuring the pin hole is aligned, then inserts the pin rod into the pin hole, and finally installs locking nuts at both ends of the pin rod to prevent it from coming off, thus completing the hook installation. This design achieves convenient hook installation, facilitates replacement by workers when the hook is damaged, and improves the convenience of worker operation.

[0017] Optionally, the hook is provided with an anti-detachment component, the hook has a receiving groove, a baffle is hinged to the inner side wall of the receiving groove, the end of the hook has an arc groove that slides with the end of the baffle, the hook is provided with a mounting plate, the mounting plate is internally threaded with a lead screw, the hook is provided with a guide sleeve that slides with the lead screw, and the end of the lead screw away from the mounting plate is hinged to the end of the baffle away from the arc groove.

[0018] By adopting the above technical solution, when the lead screw rotates, the end of the lead screw moves up and down in the vertical direction. The movement of the lead screw pushes the baffle to swing around the hinge point with the receiving groove. When the workpiece is suspended on the hook, the baffle swings into the arc-shaped through groove, thereby blocking the opening of the hook and preventing the workpiece from falling off the hook due to buoyancy when entering the plating pool, thus ensuring the smooth progress of the workpiece electroplating process.

[0019] Optionally, the baffle is provided with multiple liquid permeation holes.

[0020] By adopting the above technical solution, the setting of the liquid permeation hole allows the electroplating solution to flow smoothly around the hook and at the contact point between the workpiece and the hook. The electroplating solution can fully wet the connection area between the workpiece and the hook through the liquid permeation hole, avoiding the formation of local electroplating solution flow obstruction or liquid accumulation dead corners due to the presence of baffles, ensuring the uniformity of electroplating in this area, thereby further improving the plating quality of the workpiece to be plated.

[0021] Optionally, the connecting block is made of an insulating material.

[0022] By adopting the above technical solution, the electroplating current needs to be transmitted to the workpiece to be plated during the processing. By setting the connecting block as an insulating block, the possibility of the support frame becoming conductive is reduced, thereby reducing the possibility of accidents during the electroplating process and improving work safety.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application sets up a screw and a first motor, and adjusts the spacing between multiple connecting plates by setting up the screw and the first motor, so as to avoid the workpieces from coming into contact with each other, thereby ensuring that the outer surface of the workpiece can fully contact the electroplating solution, improving the uniformity of the workpiece coating, and thus improving the coating quality of the workpiece to be plated.

[0025] 2. This application sets up a drive assembly and a bidirectional lead screw. The drive assembly drives the bidirectional lead screw to rotate, and the rotation of the bidirectional lead screw adjusts the distance between two connecting blocks on the same connecting plate, avoiding contact between the plated parts on the same connecting plate, thereby further improving the coating quality of the workpiece to be plated.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses an electroplating suspension bracket.

[0034] Reference Figure 1 An electroplating suspension rack includes a support frame 1, which is square in shape. Multiple connecting plates 2 are slidably connected to the support frame 1. The multiple connecting plates 2 are evenly distributed at equal intervals along the support frame 1. In this embodiment, there are three connecting plates 2. Each connecting plate 2 has a connecting block 3 on its opposite sides. Each connecting block 3 is provided with a hook 4. The connecting block 3 is an insulating block, which is used to reduce the possibility of accidents caused by the conductivity of the support frame 1.

[0035] Reference Figure 1 and Figure 2 The inner sidewalls of the support frame 1 are provided with guide grooves (not shown in the figure). The length direction of the guide groove is perpendicular to the length direction of the connecting plate 2. Each end of the connecting plate 2 is fixedly connected with a guide block (not shown in the figure) that slides with the guide groove. Under the sliding cooperation of the guide block and the guide groove, the connecting plate 2 slides along the guide groove. The support frame 1 is rotatably connected with screws 5 corresponding to the three connecting plates 2. The length direction of the screws 5 is perpendicular to the length direction of the connecting plate 2. The screws 5 are threaded with the corresponding connecting plate 2 and slide through the other two connecting plates 2. The outer surface of the support frame 1 is fixedly installed with a first motor 6 corresponding to the three screws 5. The output shaft of the first motor 6 is coaxially fixedly connected to the corresponding screw 5.

[0036] The worker first places the workpiece to be plated on the hook 4. When different workpieces along the same screw 5 come into contact with each other, the worker starts different first motors 6 to control the corresponding screw 5 to rotate. The rotation of the screw 5 drives the corresponding connecting plate 2 to move left and right along the length of the screw 5, thereby adjusting the spacing between multiple connecting plates 2. When the connecting plates 2 are adjusted so that the workpieces between adjacent connecting plates 2 no longer come into contact with each other, the electroplating operation is carried out through the lifting device. This setup achieves the adjustment of the position of the hook 4, avoids the workpieces from coming into contact with each other, and ensures that the outer surface of the workpiece can fully contact the electroplating solution, improving the uniformity of the workpiece coating and thus improving the coating quality of the workpiece to be plated.

[0037] Reference Figure 2 and Figure 3 Each connecting plate 2 has a sliding groove 21 along its length. A bidirectional lead screw 22 is rotatably connected in each sliding groove 21. Two connecting blocks 3 are threadedly connected to the two sections of the bidirectional lead screw 22 with opposite thread directions. The connecting blocks 3 are slidably connected in the sliding groove 21. A drive assembly 7 for driving the bidirectional lead screw 22 to rotate is provided in the sliding groove 21.

[0038] Reference Figure 2 and Figure 3 The drive assembly 7 includes a second motor 71 fixedly connected to the end face of the connecting plate 2 away from the sliding groove 21. The output shaft of the second motor 71 is coaxially fixedly connected to a worm 72. The worm 72 extends into the sliding groove 21 and meshes with a worm wheel 73. The worm wheel 73 is fixedly sleeved on the end of the bidirectional lead screw 22. The worm wheel 73 and the worm 72 are rotatably disposed in the sliding groove 21.

[0039] When the plated parts on the same connecting plate 2 come into contact with each other, the worker starts the second motor 71. The second motor 71 drives the worm gear 72 to rotate, and the worm gear 72 drives the meshing worm wheel 73 to rotate. The rotation of the worm wheel 73 drives the bidirectional lead screw 22 to rotate in the sliding groove 21. The rotation of the bidirectional lead screw 22 drives the two connecting blocks 3 to move towards or away from each other in the sliding groove 21. The movement of the connecting blocks 3 drives the hook 4 to move, thereby adjusting the distance between the plated parts on the same connecting plate 2 and avoiding the plated parts on the same connecting plate 2 from coming into contact with each other, thereby further improving the coating quality of the workpiece to be plated.

[0040] At the same time, the self-locking characteristics of the worm gear 73 and worm 72 are used to prevent the bidirectional lead screw 22 from rotating unexpectedly during the electroplating process, which would cause the position of the hook 4 to change. This reduces quality problems such as plating defects caused by changes in the position of the hook 4, thereby further improving the plating quality of the workpiece to be plated.

[0041] Reference Figure 3 and Figure 4 Over a long period of time, hook 4 may become damaged or its conductivity may decrease, affecting the transfer of electroplating current to the workpiece to be plated, thus affecting the electroplating effect of the workpiece.

[0042] To solve the above technical problems, the hook 4 is detachably connected to the connecting block 3 via the connecting component 8. Specifically, the connecting component 8 includes a fixing block 81 fixedly connected to the hook 4 away from the hook part. The connecting block 3 has a fixing groove 31 that slides with the fixing block 81. The fixing block 81 and the connecting block 3 have interconnected pin holes 32. A pin rod 82 is slidably connected in the pin hole 32. When the pin rod 82 is inserted into the pin hole 32, both ends of the pin rod 82 are threaded with locking nuts 83.

[0043] When hook 4 needs to be disassembled, the worker rotates the locking nut 83 to disengage it from the pin 82, then pulls the pin 82 out of the pin hole 32, and finally pulls the fixing block 81 out of the fixing hole. Hook 4 is now disassembled. When hook 4 is installed, the worker slides the fixing block 81 on hook 4 into the fixing groove 31, ensuring the pin hole 32 is aligned. Then, the pin 82 is inserted into the pin hole 32. Finally, locking nuts 83 are installed at both ends of the pin 82 to prevent it from coming off. Hook 4 is now installed. This design makes hook 4 easy to install and allows workers to replace it when it is damaged, improving the ease of operation for workers.

[0044] Reference Figure 4 and Figure 5 The hook 4 is equipped with an anti-detachment component 9. Specifically, a receiving groove 41 is provided on the end face of the hook 4 away from the hook part. A baffle 91 is hinged between the inner sidewalls of the receiving groove 41. An arc groove 42 is provided at the end of the hook part of the hook 4 to slide with the baffle 91. An mounting plate 92 is fixedly connected to the outer end face of the hook 4 away from the hook part. A lead screw 93 is internally threaded to the mounting plate 92. A guide sleeve 94 is fixedly connected to the hook 4 to slide with the lead screw 93. The length direction of the guide sleeve 94 is parallel to the vertical direction. The end of the lead screw 93 away from the mounting plate 92 is hinged to the end of the baffle 91 away from the arc groove 42.

[0045] When the workpiece needs to be suspended on the hook 4, the worker rotates the lead screw 93 in the forward direction. Since the lead screw 93 is threadedly connected to the mounting plate 92 and the guide sleeve 94 restricts the movement of the lead screw 93 in the vertical direction, the lead screw 93 moves downward during the rotation. The movement of the lead screw 93 pushes the baffle 91 to swing upward around the hinge point with the receiving groove 41. The end of the baffle 91 disengages from the arc groove 42, thereby releasing the blockage of the hook 4 and facilitating the suspension of the workpiece on the hook 4. After the workpiece is suspended on the hook 4, the lead screw 93 is rotated in the reverse direction. The upward movement of the lead screw 93 causes the baffle 91 to swing downward around the hinge point with the receiving groove 41. The baffle 91 swings into the arc-shaped through groove, thereby blocking the opening of the hook 4 and preventing the workpiece from detaching from the hook 4 due to buoyancy when entering the plating tank, thus ensuring the smooth progress of the workpiece electroplating process.

[0046] Reference Figure 4 and Figure 5 The baffle 91 has multiple liquid permeation holes 10. The liquid permeation holes 10 allow the electroplating solution to flow smoothly around the hook 4 and at the contact point between the workpiece and the hook 4. The electroplating solution can fully wet the connection area between the workpiece and the hook 4 through the liquid permeation holes 10, avoiding the formation of local electroplating solution flow obstruction or liquid accumulation dead corners due to the presence of the baffle 91, ensuring the uniformity of electroplating in this area, thereby further improving the plating quality of the workpiece to be plated.

[0047] The implementation principle of an electroplating suspension rack in this application embodiment is as follows: The worker first places the workpiece to be plated on the hook 4. When different workpieces along the same screw 5 come into contact with each other, the worker starts different first motors 6 to control the corresponding screws 5 to rotate. The rotation of the screws 5 drives the corresponding connecting plates 2 to move left and right along the length of the screws 5, thereby adjusting the spacing between multiple connecting plates 2. When the connecting plates 2 are adjusted so that the workpieces between adjacent connecting plates 2 no longer come into contact with each other, the electroplating operation is carried out by the lifting device. This setting realizes the adjustment of the position of the hook 4, avoids the workpieces from coming into contact with each other, and ensures that the outer surface of the workpiece can fully contact the electroplating solution, improving the uniformity of the workpiece coating and thus improving the coating quality of the workpiece to be plated.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
