Technical Field

[0002] The copper-aluminum terminal block is an electrical connection component used to connect wires. Due to its good conductivity and corrosion resistance, it is widely used in power systems. During the processing of the copper-aluminum terminal block, workers will directly make the aluminum into the shape of the terminal block, and then pickle it - nickel-plated - copper-plated - nickel-plated - copper-plated, and attach a layer of copper coat to the surface of the aluminum terminal block as a whole, which increases the thickness and prevents the copper-aluminum terminal block from breaking.

[0003] During the processing of the copper-aluminum terminal blocks in the prior art, due to the different positions of the electrode plates and the copper-aluminum terminal blocks in the electroplating solution, some of the copper-aluminum terminal blocks are close to the electrode plates and the power supply, while the other parts are far away from the electrode plates and the power supply. As a result, the current density received by the copper-aluminum terminal blocks is easily different, which in turn causes the thickness of the electroplating material of the copper-aluminum terminal blocks to be easily different, thereby reducing the electroplating quality of the copper-aluminum terminal blocks.

[0004] In view of the above problems, it can be found that it is difficult to avoid the above problems at the same time when using the existing copper-aluminum terminal processing devices on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which cannot achieve the desired effect.

[0015] A forming method of a processing device for a copper-aluminum terminal comprises the following steps: S1: When in use, the worker first cuts the aluminum rod into a suitable length by cutting equipment, then uses stamping equipment to stamp the aluminum rod into a terminal style, and uses grinding and polishing equipment to grind and polish the terminal. Then the worker hangs the processed terminal on the outer surface of the conductive ring, so that the copper-aluminum terminal contacts the conductive ring. Then the worker clamps the limit sleeve on the outer surface of the conductive ring, and at the same time clamps the connection block inside the placement rack. Then the worker pushes the rack plate, so that the rack plate drives the rotating gear to rotate, so that the rotating gear drives the ball screw to rotate, and then the ball screw drives the T-plate to move downward, so that the T-plate is clamped inside the connection block, thereby fixing the connection rack on the placement rack, and then the worker uses a hook to hang the placement rack on the mobile rack, so that the mobile rack drives the placement rack to move. During the nickel plating and copper plating process, the mobile rack drives the placement rack to extend into the interior of the processing box, so that the conductive block contacts the conductive column, and then the negative pole of the power supply is electrically connected to each copper-aluminum terminal.

During the nickel plating and copper plating process of the copper-aluminum terminal blocks, the rotating motor is used to provide power to drive the first reciprocating screw connected to it to rotate, so that the first reciprocating screw rod cooperates with the first connecting wheel and the first belt to rotate. Another first reciprocating screw rod corresponding to the first belt drives the moving block to move back and forth, and the moving block drives the toggle plate, the fixed tube and the connecting wheel to rotate. The connecting nozzle moves, so that the toggle plate stirs the electroplating solution. At the same time, during the movement of the connecting nozzle, the power provided by the water pump is used to extract the electroplating solution on one side close to the electrode plate body to the other side, thereby ensuring that the current density inside the electroplating solution is consistent, so that the electroplating thickness of the copper and aluminum terminals is consistent. During the rotation of the first reciprocating screw, the first conical wheel drives the second conical wheel to rotate, so that the second conical wheel drives the rotating shaft and the rotating disk to rotate, and then the rotating disk drives the connecting column to rotate, and then under the restriction of the limit seat, the connecting column drives the moving frame to move back and forth, so that the moving frame drives the connecting rod to move, so that the connecting rod drives the rubber hammer to knock the processing box, thereby eliminating the bubbles generated during the mixing process; S3: During the operation of the mixing unit, the first reciprocating screw drives the second connecting wheel connected thereto to rotate, so that the second connecting wheel cooperates with the second belt to drive the third connecting wheel and the rotating shaft to rotate, and then the rotating shaft drives the tooth column and the connecting piece to rotate, so that the tooth column drives the connecting gear meshing with it to rotate, so that the connecting gear drives the rotating rod to rotate, and then the rotating rod cooperates with the third conical wheel and the fourth conical wheel to drive the rotating rod and the rotating disk to rotate, so that the rotating disk drives the fixed column to rotate, and then under the restriction of the limit block, the fixed column drives the sliding frame to move up and down, Thereby, the sliding frame drives the scraper to move up and down. At the same time, during the rotation of the connecting part, the connecting part intermittently drives the rotating part to rotate, so that the rotating part drives the second reciprocating screw to rotate intermittently, and then the second reciprocating screw drives the movable platform to move back and forth, so that the scraper moves up and down while moving back and forth intermittently, so that the scraper cleans the surface of the electrode plate body. When the electroplating of the copper-aluminum terminal is completed, the worker removes the placement rack from the mobile rack and puts the copper-aluminum terminal into the dryer for drying, thereby completing the processing of the copper-aluminum terminal.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention is provided with a mixing unit, so that during the electroplating process, the device uses a water pump to extract the plating liquid near the main body of the electrode plate to a side position away from the main body of the electrode plate, and uses a toggle plate to mix and stir the plating liquid, so that the current density inside the plating liquid is consistent, thereby avoiding different plating thicknesses of copper and aluminum terminals due to differences in current density inside the plating liquid, thereby improving the electroplating quality of the device.

[0017] The present invention is provided with an impurity removal unit, so that the device can scrape off impurities attached to the surface of the electrode plate body during the mixing of the electroplating solution, thereby avoiding the contact between the electrode plate body and the electroplating solution due to the attachment of impurities, thereby ensuring that the electrode plate body can be well ionized, and further ensuring the electroplating effect of the copper-aluminum terminal.

[0018] The present invention is provided with a placement mechanism, so that during the electroplating process, the current can fully contact each copper-aluminum terminal, thereby avoiding the phenomenon that the electroplating effect of a copper-aluminum terminal is reduced due to poor current contact. The device is provided with a processing mechanism and a placement mechanism, thereby ensuring that the current density received by the copper-aluminum terminal is consistent, thereby avoiding the phenomenon of different electroplating thicknesses on the copper-aluminum terminal, and ensuring a good electroplating effect of the copper-aluminum terminal.

The worker then clamps the limit sleeve (310) on the outer surface of the conductive ring (307), and at the same time clamps the connection block (311) inside the placement frame (301). The worker then pushes the rack plate (315), so that the rack plate (315) drives the rotating gear (314) to rotate, so that the rotating gear (314) drives the ball screw The rod (312) rotates, thereby causing the ball screw (312) to drive the T-shaped plate (313) to move downward, so that the T-shaped plate (313) is clamped inside the connecting block (311), thereby fixing the connecting frame (309) on the placement frame (301), and then the worker uses the hook (302) to hang the placement frame (301) on the movable frame (14), so that the movable frame (14) drives the placement frame (301) to move, and when the nickel plating and copper plating are performed, the movable frame (14) drives the placement frame (301) to extend into the interior of the processing box (12), so that the conductive block (304) contacts the conductive column (320), and thus the negative electrode of the power supply is electrically connected to each copper-aluminum terminal; S2: During the electroplating process of the copper-aluminum terminal blocks, the copper-aluminum terminal blocks are driven to move by the moving frame (14), so that the copper-aluminum terminal blocks repeatedly enter the interior of the processing box (12) and the cleaning box (13), and then the copper-aluminum terminal blocks are removed from the device after being degreased, cleaned, pickled, cleaned, activated, cleaned, nickel-plated, cleaned, copper-plated, cleaned, nickel-plated, cleaned, copper-plated, and cleaned in sequence. During the nickel-plating and copper-plating processes, the copper-aluminum terminal blocks are driven by the rotating motor (2105) to provide power to move the terminals connected to the processing box (12) and the cleaning box (13). The first reciprocating screw rod (2102) connected to the first belt (2104) rotates, so that the first reciprocating screw rod (2102) cooperates with the first connecting wheel (2103) and another first reciprocating screw rod (2102) corresponding to the first belt (2104) to rotate, so that the first reciprocating screw rod (2102) drives the moving block (2106) to move forward and backward, and then the moving block (2106) drives the toggle plate (2123), the fixed tube (2107) and the connecting nozzle (2108) to move, so that the toggle plate (2123) ) to stir the electroplating solution, and at the same time, during the movement of the connecting nozzle (2108), the electroplating solution on one side close to the electrode plate body (2101) is extracted to the other side by using the power provided by the water pump (2109), thereby ensuring that the current density inside the electroplating solution is consistent, so that the electroplating thickness of the copper-aluminum terminal is consistent. During the rotation of the first reciprocating screw (2102), the first conical wheel (2111) drives the second conical wheel (2114) to rotate, so that the second conical wheel (2114) drives the rotating shaft ( 2113) and the rotating disk (2115) rotate, thereby causing the rotating disk (2115) to drive the connecting column (2116) to rotate, and then under the restriction of the limit seat (2122), the connecting column (2116) drives the movable frame (2117) to move back and forth, so that the movable frame (2117) drives the connecting rod (2118) to move, so that the connecting rod (2118) drives the rubber hammer (2119) to knock the processing box (12), thereby eliminating bubbles generated during the mixing process; S3: During the operation of the mixing unit (21), the first reciprocating screw (2102) drives the second connecting wheel (2201) connected thereto to rotate, so that the second connecting wheel (2201) cooperates with the second belt (2204) to drive the third connecting wheel (2203) and the rotating shaft (2202) to rotate, and then the rotating shaft (2202) drives the tooth column (2205) and the connecting member (2206) to rotate, so that the tooth column (2205) ) drives the connecting gear (2211) meshed with it to rotate, so that the connecting gear (2211) drives the rotating rod (2210) to rotate, and then the rotating rod (2210) cooperates with the third conical wheel (2212) and the fourth conical wheel (2214) to drive the rotating rod (2213) and the rotating disk (2215) to rotate, so that the rotating disk (2215) drives the fixed column (2216) to rotate, and then the limiting block (2220) Under the restriction, the fixed column (2216) drives the sliding frame (2217) to move up and down, so that the sliding frame (2217) drives the scraper (2218) to move up and down. At the same time, during the rotation of the connecting member (2206), the connecting member (2206) intermittently drives the rotating member (2208) to rotate, so that the rotating member (2208) drives the second reciprocating screw (2207) to rotate intermittently, and then the second reciprocating screw (2207) drives the moving platform (2209) to move forward and backward, so that the scraper (2218) moves up and down while moving intermittently forward and backward, so that the scraper (2218) cleans the surface of the electrode plate body (2101). When the electroplating of the copper-aluminum terminal is completed, the worker removes the placement rack (301) from the mobile frame (14) and puts the copper-aluminum terminal into the dryer for drying, thereby completing the processing of the copper-aluminum terminal.
