Description

Technical Field

[0001] This invention relates to the field of electroplating technology, specifically to a copper plating equipment for plastic sheets. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. 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 (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhancing aesthetics. Plastic electroplating involves electroplating plastic products after they have undergone conductive pretreatment, in order to obtain lightweight, low-cost, and aesthetically pleasing products, such as mobile phone casings with a metallic luster, door handles, and automotive trim parts, with decoration as the primary purpose.

[0003] Current electroplating techniques for plastics are challenging and complex, requiring pretreatment to make the plastic sheet conductive before electroplating. Repeating this process leads to low copper plating efficiency, cumbersome operation, and the generation of various precipitates and impurities during electroplating, which affects the plating results. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a copper plating equipment for plastic plates, which solves the problems of low efficiency and poor copper plating effect in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a copper plating equipment for plastic plates, comprising an electroplating tank, a frame plate fixedly connected to the front of the top of the electroplating tank, a DC power supply fixedly connected to the top of the frame plate, a sleeve plate fixedly connected to the rear of the bottom of the frame plate, a conductive sheet fixedly connected to the inner wall of the front end of the sleeve plate, a conductive spring fixedly connected to the front end of the conductive sheet, a telescopic plate fixedly connected to the front end of the conductive spring, the outer wall of the telescopic plate slidably connected to the inner wall of the sleeve plate, a linear motor fixedly connected to the rear of the top of the electroplating tank, a sliding plate fixedly connected to the drive end of the linear motor, electric push rods fixedly connected to both sides of the front end of the sliding plate, a bearing plate fixedly connected to the drive end of each electric push rod, a cylinder fixedly connected to the front end of each bearing plate, a pressure plate fixedly connected to the drive end of each cylinder, a conductive plate fixedly connected to the rear of the top of each bearing plate, and a slot provided at the bottom of each bearing plate.

[0006] Preferably, each of the conductive plates has an arc surface at its front end, and each of the telescopic plates has an arc groove at its front end, the arc grooves being adapted to the arc surfaces of the corresponding conductive plates.

[0007] Preferably, a copper plate is disposed at the rear of the interior of the electroplating tank, the copper plate being electrically connected to the positive terminal of the DC power supply, and the conductive sheet being electrically connected to the negative terminal of the DC power supply.

[0008] Preferably, a spraying box is provided on both sides of the electroplating tank, a plate placement groove is provided on the outer top of the spraying box, a guide plate is fixedly connected to the bottom of the plate placement groove, a baffle is fixedly connected to the inner wall of the front end of the spraying box below the guide plate, a graphite nozzle is installed at the bottom of the inner wall of both the front and rear ends of the spraying box, and a drying fan is installed on the inner wall of the spraying box above the graphite nozzle.

[0009] Preferably, a connecting plate is fixedly connected to the middle of the rear end of the slide plate, a rack is fixedly connected to the bottom end of the connecting plate, a gear is meshed with the bottom end of the rack, a rotating shaft is fixedly connected to the front end of the gear, the rear end of the rotating shaft passes through the rear end of the electroplating tank and is fixedly connected to a plastic filter frame, and the outer wall of the rotating shaft is rotatably connected to the inner wall of the electroplating tank.

[0010] Preferably, a sealing ring is fixedly connected to the rear end of the electroplating tank at the position corresponding to the rotating shaft.

[0011] Preferably, a partition plate is slidably connected to the middle of the electroplating tank, and the partition plate has multiple through holes inside.

[0012] Preferably, a receiving box is fixedly connected to both the left and right ends of the electroplating tank, and a drain pipe is fixedly connected to the bottom of the front end of the electroplating tank.

[0013] Working principle: The plastic sheet first falls into the inclined chute and is guided to the baffle by the guide plate. A cylinder drives the pressure plate forward, clamping the end of the plastic sheet between the pressure plate and the conductive plate. Then, an electric push rod moves downward, bringing the plastic sheet to the graphite nozzle at the bottom of the spray box for graphite spraying. After spraying, the electric push rod lifts the plastic sheet up, and a drying fan dries it. Then, a linear motor drives a sliding plate to move the plastic sheet above the electroplating tank. Finally, an electric push rod moves downward again, immersing the plastic sheet in the electroplating solution in the tank. At this point, the conductive plate is inserted into the arc-shaped groove of the telescopic plate. When the DC power is connected, the plastic plate is electroplated. By setting up a bidirectional spray box, one plastic plate can be electroplated while another plastic plate is being graphite-coated. Simultaneously, as the slide plate moves left and right, the connecting plate drives the rack to move, which in turn drives the gear to rotate. The gear drives the plastic filter frame to flip, which flips the sediment from the electroplated plastic plate to the bottom of the electroplating tank before electroplating the other plastic plate, thus preventing impurities from affecting the electroplating effect.

[0014] This invention provides a copper plating device for plastic sheets. It has the following beneficial effects:

[0015] 1. This invention uses a cylinder to drive a pressure plate forward, clamping the end of a plastic sheet between the pressure plate and a conductive plate. Then, an electric push rod moves downward to bring the plastic sheet to the graphite nozzle at the bottom of the spray box for graphite spraying. After spraying, the electric push rod lifts the plastic sheet upward and a drying fan dries it, which can pre-treat the plastic sheet and make it conductive. At the same time, by setting a bidirectional spray box, one plastic sheet can be electroplated while another electroplating sheet is being graphite sprayed. Furthermore, the plastic sheet can be automatically connected to the power supply when it reaches the electroplating tank, thus automatically completing the electroplating and improving the electroplating efficiency.

[0016] 2. In this invention, the sliding plate moves left and right, driving the rack and pinion through the connecting plate, which in turn drives the gear to rotate. The gear then drives the plastic filter frame to flip, which flips the deposited impurities from the electroplating of the plastic plate that has been electroplated first to the bottom of the electroplating tank before electroplating another plastic plate, thus preventing impurities generated during electroplating from affecting the electroplating effect.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example:

[0027] like Figure 1-7 As shown, this embodiment of the invention provides a copper plating equipment for plastic plates, including an electroplating tank 1. A frame plate 2 is fixedly connected to the front of the top of the electroplating tank 1. A DC power supply 4 is fixedly connected to the top of the frame plate 2. A sleeve plate 19 is fixedly connected to the rear of the bottom of the frame plate 2. A conductive sheet 28 is fixedly connected to the inner wall of the front end of the sleeve plate 19. A conductive spring 27 is fixedly connected to the front end of the conductive sheet 28. A telescopic plate 18 is fixedly connected to the front end of the conductive spring 27. The outer wall of the telescopic plate 18 is slidably connected to the inner wall of the sleeve plate 19. A linear motor 6 is fixedly connected to the rear of the top of the electroplating tank 1. A sliding plate 5 is fixedly connected to the drive end of the linear motor 6. Electric push rods 13 are fixedly connected to both sides of the front end of the sliding plate 5. A bearing plate 14 is fixedly connected to the drive end of each electric push rod 13. A cylinder 15 is fixedly connected to the front end of each bearing plate 14. The cylinder 15 is driven by... Each end of the plastic plate is fixedly connected to a pressure plate 16. Each top rear of the support plate 14 is fixedly connected to a conductive plate 20. Each bottom end of the support plate 14 is provided with a groove 17. Each front of the conductive plate 20 is provided with an arc surface. Each front end of the telescopic plate 18 is provided with an arc groove 26. The arc groove 26 is adapted to the arc surface of the corresponding conductive plate 20. The plastic plate is positioned at the groove 17. The cylinder 15 drives the pressure plate 16 to move forward and clamps the end of the plastic plate between the pressure plate 16 and the conductive plate 20. The linear motor 6 drives the slide plate 5 to move the plastic plate to the top of the electroplating tank 1. The electric push rod 13 moves downward to immerse the plastic plate in the electroplating solution of the electroplating tank 1. At this time, the conductive plate 20 squeezes the telescopic plate 18 to compress the conductive spring 27 and lock it in the arc groove 26 of the telescopic plate 18. The DC power supply 4 is connected to realize the electroplating of the plastic plate.

[0028] A copper plate 12 is installed at the rear of the electroplating tank 1. The copper plate 12 is electrically connected to the positive terminal of the DC power supply 4, and the conductive sheet 28 is electrically connected to the negative terminal of the DC power supply 4, thus forming a complete circuit.

[0029] Spraying boxes 3 are installed on both sides of the electroplating tank 1. A plate-laying chute 21 is installed on the outer top of each spraying box 3. A guide plate 22 is fixedly connected to the bottom of each plate-laying chute 21. A baffle 23 is fixedly connected to the inner wall of the front end of each spraying box 3 below the guide plate 22. Graphite nozzles 25 are installed at the bottom of the inner walls at both the front and rear ends of each spraying box 3. A drying fan 24 is installed above each graphite nozzle 25 on the inner wall of each spraying box 3. The plastic sheet first falls into the spraying box through the plate-laying chute 21 and is then... The guide plate 22 guides the plastic sheet to the baffle 23. The cylinder 15 drives the pressure plate 16 to move forward and clamps the end of the plastic sheet between the pressure plate 16 and the conductive plate 20. Then, the electric push rod 13 moves downward to bring the plastic sheet to the graphite nozzle 25 at the bottom of the spray box 3 for graphite spraying. After the spraying is completed, the electric push rod 13 drives the plastic sheet to rise and the drying fan 24 dries the plastic sheet. This pre-treatment of the plastic sheet makes it conductive, which is convenient for subsequent copper plating.

[0030] A connecting plate 7 is fixedly connected to the middle of the rear end of the slide plate 5. A rack 8 is fixedly connected to the bottom end of the connecting plate 7. A gear 9 is meshed with the bottom end of the rack 8. A rotating shaft 30 is fixedly connected to the front end of the gear 9. The rear end of the rotating shaft 30 passes through the rear end of the electroplating tank 1 and is fixedly connected to a plastic filter frame 29. The outer wall of the rotating shaft 30 is rotatably connected to the inner wall of the electroplating tank 1. During the left and right movement of the slide plate 5, the rack 8 is driven to move through the connecting plate 7, thereby driving the gear 9 to rotate. The gear 9 drives the plastic filter frame 29 to flip, which can flip the sediment and impurities from the electroplating of the plastic plate that has been electroplated first to the bottom of the electroplating tank 1, and then electroplat another plastic plate, preventing impurities generated during electroplating from affecting the electroplating effect.

[0031] A sealing ring 31 is fixedly connected to the rear end of the electroplating tank 1 at the position corresponding to the rotating shaft 30. The sealing ring 31 improves the sealing performance of the electroplating tank 1 and prevents the electroplating solution from leaking out.

[0032] An isolation plate 11 is slidably connected to the middle of the electroplating tank 1. The isolation plate 11 has multiple through holes inside. By setting the isolation plate 11, the copper plate 12 can be prevented from directly contacting the plastic plate, which would cause a short circuit and lead to copper plating failure.

[0033] Both ends of the electroplating tank 1 are fixedly connected to receiving boxes 10. During the process of switching copper-plated plastic plates, the cylinder 15 drives the pressure plate 16 to relax, and the electroplated plastic plates can fall into the receiving boxes 10 for collection. The bottom of the front end of the electroplating tank 1 is fixedly connected to a drain pipe 32, which facilitates the discharge of electroplating solution and impurities.
