Description

Technical Field

[0001] This utility model relates to a double-sided plating fixture, and more particularly to a double-sided plating fixture that can adapt to the integration of multiple small products. Background Technology

[0002] Existing double-sided plating racks for small products often use a single-piece clamping method. Small product plating is usually paired with small plating tanks, typically small hand-operated machines. The tanks of these machines are often unable to accommodate large-sized product racks. To meet the production requirements of products of different sizes and to improve production efficiency, it is often necessary to accommodate small racks within large tanks. However, single-piece clamping racks only plate one piece at a time during production, which greatly wastes the space of large tanks and reduces output. Therefore, to solve the problem of plating multiple small products at once in large tanks, a double-sided plating rack that can accommodate multiple small products is particularly important. Utility Model Content

[0003] The purpose of this invention is to provide a double-sided plating fixture that can accommodate the integration of multiple small products. It can meet the double-sided electroplating production of multiple small products in a large electroplating tank, greatly improving the space utilization rate of small products in the electroplating tank and increasing the production efficiency of electroplating.

[0004] This utility model provides the following technical solution: A double-sided plating fixture capable of accommodating the integration of multiple small products includes a main body module with multiple sets of through holes I and a cover plate module with multiple sets of through holes II. The through holes I and through holes II are arranged in a one-to-one correspondence. The main body module and the cover plate module are connected to cover and clamp the products to be electroplated between the through holes I and through holes II in a one-to-one correspondence. The design of through holes one and two ensures that when the product is clamped between through holes one and two, the fluid in the electroplating tank can contact both sides of the product. The double-sided plating fixture of this invention can be adapted to meet the double-sided electroplating production of multiple small products in a large electroplating tank, greatly improving the space utilization rate of small products in the electroplating tank and improving the production efficiency of electroplating.

[0005] Preferably, the main body module includes a main body base plate with multiple sets of through holes. A mounting groove is also provided on one side of the main body base plate. A conductive sheet is disposed in the mounting groove. A through hole corresponding to the through hole is provided in the conductive sheet. A sealing ring and a pressure plate for pressing and fixing the sealing ring to the main body base plate are arranged around the periphery of each set of through holes. A positioning pin for positioning around the product is also provided around the through hole to facilitate product fixation. The conductive teeth on the conductive sheet pass through the reserved holes of the sealing ring and the pressure plate and abut against one side of the product.

[0006] Preferably, the cover plate module includes a cover base plate with multiple sets of through holes II, the through holes II and through holes I being configured in a one-to-one correspondence. A mounting groove II is provided on one side of the cover base plate, and a conductive sheet II is disposed within the mounting groove II. A through hole II is provided within the conductive sheet II, communicating with the through holes II. A sealing ring II and a pressure plate II for pressing and fixing the sealing ring II onto the cover base plate are arranged around the periphery of each set of through holes II. The conductive teeth on the conductive sheet II pass through the reserved holes of the sealing ring II and the pressure plate II and abut against the other side of the product. This ensures that the hanging fixture sealing structure of this utility model is simple and reliable, the conductive method is easy to maintain, and the reliable sealing performance prevents product defects caused by leakage during the electroplating process. At the same time, the separate conductive structure of the cover plate and the main body ensures reliable contact connection, making the electroplating process of double-sided plated products more stable.

[0007] Preferably, the main body base plate also includes a first conductive circuit and a second conductive circuit. The two sides of the main body base plate are also provided with first conductive contacts and second conductive contacts respectively connected to the first and second conductive circuits. Two sets of conductive screws on the main body base plate are used to press down the first conductive sheet and connect to both ends of the first conductive circuit. The bottom ends of two sets of conductive posts on the main body base plate are connected to both ends of the second conductive circuit, and the top ends of the two sets of conductive posts extend out of the main body base plate and abut against the contacts of the second conductive sheet. A clamping pad, made of silicone, is provided on the bottom side of the contacts of the second conductive sheet, spaced between the cover base plate and the second conductive sheet. The clamping pad provides elastic support under pressure. When the main body module and the cover plate module are closed, the protruding... The conductive post presses onto the contact of the second conductive sheet, supported by the clamping pad directly below the contact of the second conductive sheet, forming a circuit connection. At this time, the conductive post and the second conductive sheet are connected to the conductive contact of the main module through the second conductive circuit, and connected to the external power supply to achieve conductivity. This structure is easy to maintain and is simpler and more reliable than traditional clamping or spring contacts. The conductivity on both sides of the product is as follows: the conductive screw presses the first conductive sheet and connects it to the first conductive circuit on the back of the main body base plate to form the conductive circuit on the base plate side. The bottom plate side of the cover is connected to the second conductive circuit through the conductive post passing through the main body base plate to form the conductive circuit on the cover plate side. The first conductive circuit and the second conductive circuit are finally connected to the first conductive contact and the second conductive contact, respectively.

[0008] Preferably, the first pressure plate, the first sealing ring, the first conductive sheet and the main body base plate are fixedly connected by a first fixing screw, and the second pressure plate, the second sealing ring, the second conductive sheet and the cover base plate are fixedly connected by a second fixing screw.

[0009] Preferably, a set of O-rings is also provided around the periphery of the second mounting groove to form an outer seal on the hanger.

[0010] Preferably, the inner ring of the O-ring is further provided with a locking screw for securing the main body module and the cover plate module, and a sealing washer is installed in the countersunk hole of the locking screw to improve the sealing performance.

[0011] Preferably, both sealing ring one and sealing ring two are provided with clearance holes and locking holes, and the clearance holes and locking holes are distributed at intervals. The locking holes are holes corresponding to the holes through which fixing screw one or fixing screw two passes. The clearance hole of sealing ring one is used to avoid the head of fixing screw one, and the clearance hole of sealing ring two is used to avoid the head of fixing screw two. Thus, when the main body module and the cover plate module are pressed together, a double-protruding sealing form is formed, which effectively ensures that the protruding part can be evenly pressed on the sealing ring during the pressing process, achieving a complete sealing effect, ensuring more reliable fixation, and saving more space.

[0012] Preferably, a square nut is inlaid on the main body base plate and sealed with sealant to achieve partial sealing of the nut. The sealing washer is installed in the countersunk hole of the cover base plate. The locking screw is a hexagonal screw, which is used to pass through the sealing washer and lock it in the square nut. After tightening, the gaps at both ends are compensated by the sealing washer and the sealant, respectively, so as to achieve a more effective and reliable seal of the hanger.

[0013] The beneficial effects of this utility model are as follows: This utility model hanger is mainly designed for use in existing large tanks when switching from large products to small products for electroplating. It can simultaneously plate multiple small products on both sides, thereby improving the space utilization rate of small products in the electroplating tank and thus improving the production efficiency of product electroplating. It consists of two main parts: a main body module and a cover plate module. The main body of the hanger is based on a main body base plate with three through holes for fluid contact. A conductive sheet is first installed in the mounting groove of the main body base plate, and a sealing ring is installed above the conductive sheet. The conductive teeth of the conductive sheet are led out from the pre-drilled holes in the sealing ring, and then a pressure plate is pressed on for locking. Positioning pins are installed around the sealing ring to facilitate product fixation. In the center of the main body, the conductive sheet is connected to the first conductive circuit via conductive screws. There are also two conductive posts on the main body base plate, which are also connected to the second conductive circuit on the back, and finally connected to conductive contacts. The cover plate module is based on a cover base plate with three through holes for fluid contact. For contact with fluid, conductive sheet two is first installed in the mounting groove two of the cover bottom plate. A sealing ring two is installed above conductive sheet two. The conductive teeth of conductive sheet two are led out from the reserved hole of sealing ring two. Then, pressure plate two is pressed on and locked. When the product is placed on the main module and connected to the cover module, the protruding conductive post will press on the contact of conductive sheet two. The clamping pad directly below the contact of conductive sheet two provides support, forming a circuit connection. At this time, the conductive post and conductive sheet two are connected to the conductive contact of the main module through conductive circuit two, and connected to the external power supply to achieve conduction. This structure is easy to maintain and is simpler and more reliable than traditional clamping or spring contacts. The conduction on both sides of the product is as follows: the conductive screw presses conductive sheet one to connect to conductive circuit one on the back of the main bottom plate to form a conductive circuit on the bottom plate side. The bottom plate side of the cover is connected to conductive circuit two through conductive post through the main bottom plate to form a conductive circuit on the cover plate side. Conductive circuit one and conductive circuit two are finally connected to conductive contact one and conductive contact two respectively. The new hanging fixture has a simple and reliable sealing structure, and its conductive method is easy to maintain. The reliable sealing performance ensures that product defects caused by leakage will not occur during the electroplating process. At the same time, the separate conductive structure of the cover plate and the main body makes the contact connection reliable, making the electroplating process of double-sided plated products more stable.

[0015] like Figure 1-10 As shown, a double-sided plating fixture capable of accommodating multiple small products 3 is provided in this embodiment. It includes a main body module 1 with multiple sets of through holes 1 and a cover plate module 2 with multiple sets of through holes 2. The through holes 1 and through holes 2 are arranged in a one-to-one correspondence. The main body module 1 and the cover plate module 2 are connected to cover and clamp the products 3 to be electroplated between the through holes 1 and through holes 2 in a one-to-one correspondence. The design of through holes one and two ensures that when product 3 is clamped between through holes one and two, the fluid in the electroplating tank can contact both sides of product 3. The double-sided plating fixture of this invention can be adapted to meet the double-sided electroplating production of multiple small products 3 in a large electroplating tank, which greatly improves the space utilization rate of small products 3 in the electroplating tank and improves the production efficiency of electroplating.

[0016] like Figure 2-5As shown, the main body module 1 includes a main body base plate 11 with multiple sets of through holes. A mounting groove is also provided on one side of the main body base plate 11. A conductive sheet 12 is disposed in the mounting groove. A through hole corresponding to the through hole is provided in the conductive sheet 12. A sealing ring 13 and a pressure plate 14 for pressing and fixing the sealing ring 13 to the main body base plate 11 are arranged around the periphery of each through hole. A positioning pin 15 for positioning around the product 3 is also provided around the through hole to facilitate the fixing of the product 3. The conductive teeth on the conductive sheet 12 pass through the reserved holes of the sealing ring 13 and the pressure plate 14 and abut against one side of the product 3.

[0017] like Figure 6-7 As shown, the cover plate module 2 includes a cover base plate 21 with multiple sets of through holes 2. The through holes 2 and through holes 1 are connected in a one-to-one manner. A mounting groove 2 is opened on one side of the cover base plate 21, and a conductive sheet 22 is disposed in the mounting groove 2. A through hole 2 is opened in the conductive sheet 22, which is connected to the through hole 2. A set of sealing rings 23 and a pressure plate 24 for pressing and fixing the sealing rings 23 to the cover base plate 21 are arranged around each set of through holes 2. The conductive teeth on the conductive sheet 22 pass through the reserved holes of the sealing rings 23 and the pressure plate 24 and abut against the other side of the product 3. Thus, the hanging fixture sealing structure of this utility model is simple and reliable, and the conductive method is easy to maintain. The reliable sealing performance ensures that the product 3 will not be defective due to leakage during the electroplating process. At the same time, the separate conductive structure of the cover plate and the main body makes the contact connection reliable, making the electroplating process of the double-sided plated product 3 more stable.

[0018] The main body base plate 11 is also provided with a first conductive circuit 19 and a second conductive circuit 25. The two sides of the main body base plate 11 are also provided with first conductive contacts 16 and second conductive contacts 26, which are respectively connected to the first conductive circuit 19 and the second conductive circuit 25. Two sets of conductive screws 17 on the main body base plate 11 are used to press down the first conductive sheet 12 and connect to both ends of the first conductive circuit 19. The bottom ends of two sets of conductive posts 27 on the main body base plate 11 are connected to both ends of the second conductive circuit 25, and the top ends of the two sets of conductive posts 27 extend out of the main body base plate 11 and abut against the contacts of the second conductive sheet 22. A clamping pad 28 (e.g., ...) is provided on the bottom side of the contacts of the second conductive sheet 22, spaced between the cover base plate 21 and the second conductive sheet 22. Figure 10As shown), the clamping pad 28 is made of silicone and can provide a certain elastic support when under pressure. When the main body module 1 and the cover module 2 are closed, the protruding conductive post 27 will press on the contact of the conductive sheet 22, and the clamping pad 28 directly below the contact of the conductive sheet 22 will provide support, forming a circuit connection. At this time, the conductive post 27 and the conductive sheet 22 are connected to the conductive contact of the main body module 1 through the conductive circuit 25, and connected to the external power supply to achieve conduction. This structure is easy to maintain and is simpler and more reliable than traditional clamping plates or spring contacts. The conduction on both sides of the product 3 is as follows: the conductive screw 17 presses the conductive sheet 12 and connects to the conductive circuit 19 on the back of the main body base plate 11 to form a conductive circuit on the base plate side. The cover base plate 21 side is connected to the conductive circuit 25 through the conductive post 27 through the main body base plate 11 to form a conductive circuit on the cover plate side. The conductive circuit 19 and the conductive circuit 25 are finally connected to the conductive contact 16 and the conductive contact 26 respectively.

[0019] The pressure plate 14, sealing ring 13, conductive sheet 12 and main body base plate 11 are fixedly connected by fixing screw 18, and the pressure plate 24, sealing ring 23, conductive sheet 22 and cover base plate 21 are fixedly connected by fixing screw 29.

[0020] A set of O-rings 210 is also provided around the periphery of the mounting groove 2 to form an outer seal on the hanger.

[0021] like Figure 9 As shown, the inner ring of the O-ring 210 is also provided with a locking screw 4 for locking the main body module 1 and the cover plate module 2. A sealing washer 7 is also installed in the countersunk hole of the locking screw 4 to improve the sealing performance.

[0022] like Figure 9 As shown, a square nut 5 is inlaid on the main body base plate 11 and sealed with sealant 6 to achieve partial sealing of the nut. The sealing washer 7 is installed in the countersunk hole of the cover base plate 21. The locking screw 4 is a hexagonal screw, which is used to pass through the sealing washer 7 and lock it in the square nut 5. After tightening, the gaps at both ends are compensated by the sealing washer 7 and the sealant 6 respectively, so as to achieve a more effective and reliable seal of the hanger.

[0023] Both sealing ring 13 and sealing ring 23 have clearance holes 8 and locking holes 9, which are spaced apart. The locking holes 9 are for the fastening screw 18 or fastening screw 29 to pass through. The clearance hole 8 of sealing ring 13 is for the clearance of the head of fastening screw 18, and the clearance hole 8 of sealing ring 23 is for the clearance of the head of fastening screw 29. Thus, when the main body module 1 and the cover plate module 2 are pressed together, a double-sided convex sealing form is formed (e.g., Figure 8As shown in the figure, this effectively ensures that the raised part can be evenly compressed during the pressing process, achieving a complete sealing effect, ensuring more reliable fixation, and saving more space.

[0024] The working principle of this utility model is as follows: This utility model hanger is mainly designed for use in existing large tanks when switching from large products 3 to small products 3 for electroplating. It can simultaneously plate multiple small products 3 on both sides, thereby improving the space utilization rate of the electroplating tank and thus improving the production efficiency of product 3 electroplating. It consists of two main parts: a main body module 1 and a cover plate module 2. The main body of the hanger is based on a main body base plate 11, which has three through holes for contact with fluid. Conductive sheets 12 are first installed in the mounting groove of the main body base plate 11. A sealing ring 13 is installed above the conductive sheet 12. The conductive teeth of the conductive sheet 12 are led out from the pre-drilled holes in the sealing ring 13. Then, the pressure plate 14 is pressed on and locked in place. Positioning pins 15 are installed around the sealing ring 13 to facilitate the fixation of the product 3. In the center of the main body, the conductive sheet 12 is connected to the first conductive circuit through the conductive screw 17. There are also two conductive posts 27 on the main body base plate 11, which are also connected to the second conductive circuit on the back, and finally connected to the conductive contacts. The cover module 2 is based on the cover base plate 21, which has three through holes for fluid contact. First, a conductive sheet 22 is installed in the mounting groove 2 of the bottom plate 21 of the cover. A sealing ring 23 is installed above the conductive sheet 22. The conductive teeth of the conductive sheet 22 are led out from the pre-drilled holes in the sealing ring 23. Then, a pressure plate 24 is pressed on and locked in place. After the product 3 is placed on the main module 1 and connected to the cover module 2, the protruding conductive post 27 will press on the contact point of the conductive sheet 22. The clamping pad 28 directly below the contact point of the conductive sheet 22 provides support, forming a circuit connection. At this time, the conductive post 27 and the conductive sheet 22 are connected to the main module 1 through the conductive circuit 25. The conductive contacts are connected to an external power source to achieve conductivity. This structure is easy to maintain and is simpler and more reliable than traditional clip or spring contacts. The conductivity on both sides of the product 3 is as follows: the conductive screw 17 presses the conductive sheet 12 to connect to the conductive circuit 19 on the back of the main body base plate 11 to form a conductive circuit on the base plate side. The cover base plate 21 side is connected to the conductive circuit 25 through the conductive post 27 passing through the main body base plate 11 to form a conductive circuit on the cover plate side. The conductive circuit 19 and the conductive circuit 25 are finally connected to the conductive contact 16 and the conductive contact 26 respectively. The new hanging fixture has a simple and reliable sealing structure, and its conductive method is easy to maintain. The reliable sealing ensures that product 3 will not be damaged due to leakage during the electroplating process. At the same time, the separate conductive structure of the cover plate and the main body makes the contact connection reliable, making the electroplating process of double-sided plated product 3 more stable.
