Description

Technical Field

[0001] This utility model relates to the field of automotive terminal electroplating technology, specifically to an electroplating equipment for automotive terminal production. Background Technology

[0002] Automotive terminals are key connection components in vehicle electrical systems, primarily used for reliable connections between wires and equipment, circuit boards, or other terminals, ensuring the stability of signal transmission and power delivery. They are mostly made of copper alloys (such as brass and phosphor bronze) or steel, possessing high conductivity, mechanical strength, and fatigue resistance. Types include pins, sockets, and spring contacts. Automotive terminal electroplating involves depositing a metal plating layer on the surface through an electrolytic process to improve corrosion resistance, conductivity, and weldability.

[0003] Existing automotive terminals still have the following problems in the actual electroplating process:

[0004] When electroplating small automotive terminals (such as pins and springs), the terminals are placed directly into the electroplating bath for the electroplating operation. However, the position of the automotive terminals is fixed during the electroplating process, which prevents a more comprehensive electroplating operation and reduces the actual electroplating effect, hindering more efficient and effective electroplating.

[0005] Therefore, this utility model introduces an electroplating equipment for the production of automotive terminals. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an electroplating equipment for automotive terminal production, which has the advantage of being able to perform electroplating more comprehensively and solves the problems mentioned in the background technology.

[0007] This utility model provides the following technical solution: an electroplating equipment for automotive terminal production, comprising a base, an electroplating tank, and a U-shaped frame. The bottom of the U-shaped frame is provided with a reciprocating tilting mechanism, which includes a second U-shaped frame, a connecting rod, a first gear, a first rack, a second rack, and a second gear. The front and rear sides of the second U-shaped frame are fitted to the inner sides of the first U-shaped frame. The outer surface of the connecting rod is rotatably connected to the interior of the first U-shaped frame. The outer surface of the connecting rod is fixedly installed to the interior of the second U-shaped frame. The interior of the first gear is fixedly connected to the outer surface of one end of the connecting rod. The interior of the second gear is fixedly connected to the outer surface of the other end of the connecting rod. The front of the first rack is fixedly installed to the back of the interior of the electroplating tank. The back of the second rack is fixedly installed to the front of the interior of the electroplating tank.

[0008] Preferably, guide rods are fixedly installed on both sides of the U-shaped frame, and extension plates are fixedly installed on both sides of the upper surface of the base. The outer surface of the extension plate is slidably connected to the inner wall of the guide rod, and one end of the extension plate is fixedly installed to the bottom of the receiving plate.

[0009] Preferably, a placement box is fixedly installed at the bottom of the second U-shaped frame, a hollow card plate is snapped into the center of the placement box, and a sealing block is snapped into the right side of the placement box.

[0010] Preferably, the first rack is installed at a higher position than the second rack, the first rack and the second rack are exactly the same size and shape, and the first gear and the second gear are exactly the same size and shape.

[0011] Preferably, the bottom of the electroplating tank is fixedly installed on the upper surface of the base, and a sealing block is snapped into the inside of the electroplating tank.

[0012] Preferably, a support plate is fixedly installed on both sides of the upper surface of the base, and a receiving plate is fixedly installed on the upper surface of the support plate.

[0013] Preferably, a hydraulic rod is fixedly installed at the center of the top of the receiving plate, and one end of the output shaft of the hydraulic rod is fixedly connected to the top of the U-shaped frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This type of electroplating equipment for automotive terminals uses a hydraulic rod to drive the U-shaped frame to rise and fall. Combined with gears one and two, as well as racks and pinions two, this allows the terminals placed in the box to swing left and right, effectively agitating the electroplating solution, preventing bubble accumulation and uneven ion distribution, and ensuring consistent plating thickness. The use of a perforated plate allows for the placement of multiple layers of automotive terminals, achieving higher efficiency and solving the problem of more comprehensive electroplating of automotive terminals. This results in a more efficient electroplating operation and facilitates convenient operation in practice.

[0016] 2. This type of electroplating equipment for automotive terminal production provides precise vertical guidance for the lifting and lowering movement of the U-shaped frame through the sliding cooperation between the guide rod and the extension plate. This effectively prevents swaying or shaking that may occur when the hydraulic rod is pushed. The fixed connection between the extension plate and the receiving plate evenly distributes the thrust of the hydraulic rod to the guide rods on both sides, reducing the risk of single-point stress and extending the service life of key components of the equipment. This solves the problem of how to ensure greater stability when the device is lifted and lowered, making it more convenient to operate and facilitating stable use. It also ensures safe and efficient use in practice. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 2 , Figure 3 and Figure 4An electroplating device for automotive terminal production includes a base 1, an electroplating tank 4, and a U-shaped frame 7. A reciprocating tilting mechanism is provided at the bottom of the U-shaped frame 7. This mechanism includes a second U-shaped frame 8, a connecting rod 9, a gear 10, a rack 11, a rack 12, and a gear 13. The front and rear sides of the second U-shaped frame 8 are fitted against the inner sides of the first U-shaped frame 7. The outer surface of the connecting rod 9 is rotatably connected to the interior of the first U-shaped frame 7, and the outer surface of the connecting rod 9 is fixedly installed to the interior of the second U-shaped frame 8. The interior of the gear 10 is fixedly connected to the outer surface of one end of the connecting rod 9. The gear 13... The inner surface of the rack is fixedly connected to the outer surface of the other end of the connecting rod 9. The front of the rack 11 is fixedly installed to the back of the electroplating tank 4. The back of the rack 212 is fixedly installed to the front of the electroplating tank 4. The bottom of the U-shaped frame 28 is fixedly installed with a placement box 14. A hollow card plate 15 is snapped into the center of the placement box 14. A sealing block 216 is snapped into the right side of the placement box 14. The installation position of the rack 11 is higher than the installation position of the rack 212. The rack 11 and rack 212 are exactly the same in size and shape. The gear 10 and gear 213 are exactly the same in size and shape.

[0024] Specifically, when the U-shaped frame 2 8 moves the connecting rod 9, gear 1 10 and gear 2 13 mesh with rack 1 11 and rack 2 12 respectively. Due to the height difference between rack 1 11 and rack 2 12, gear 1 10 and gear 2 13 generate a height difference during movement, which in turn drives the connecting rod 9 to rotate, achieving the effect of reciprocating tilting motion of the U-shaped frame 2 8. This reciprocating tilting motion allows the automotive terminals placed in the placement box 14 to continuously flip during the electroplating process, improving the uniformity of electroplating and enhancing the electroplating quality. The hollow card plate 15 facilitates full contact between the electroplating solution and the automotive terminals, improving electroplating efficiency. The sealing block 2 16 can seal the placement box 14 to prevent the automotive terminals from falling off during the electroplating process. At the same time, in conjunction with the reciprocating tilting motion of the U-shaped frame 2 8, the automotive terminals can be better flipped within the placement box 14, further optimizing the electroplating effect.

[0025] Please see Figure 1 Guide rods 18 are fixedly installed on both sides of the U-shaped frame 7, and extension plates 17 are fixedly installed on both sides of the upper surface of the base 1. The outer surface of the extension plate 17 is slidably connected to the inner wall of the guide rods 18, and one end of the extension plate 17 is fixedly installed to the bottom of the receiving plate 3.

[0026] Specifically, during the operation of the electroplating equipment, the U-shaped frame 7 may sway or deviate due to various factors. The sliding connection structure between the guide rod 18 and the extension plate 17 can restrict the U-shaped frame 7 to move smoothly in a specific direction, ensuring the accuracy of its movement trajectory. This ensures the stability of the entire reciprocating tilting mechanism and the movement of the automotive terminals in the placement box 14, thereby improving the electroplating quality.

[0027] Please see Figure 1 and Figure 2 The bottom of the electroplating tank 4 is fixedly installed on the upper surface of the base 1. A sealing block 5 is snapped into the inside of the electroplating tank 4. Support plates 2 are fixedly installed on both sides of the upper surface of the base 1. A receiving plate 3 is fixedly installed on the upper surface of the support plate 2. A hydraulic rod 6 is fixedly installed at the center of the top of the receiving plate 3. One end of the output shaft of the hydraulic rod 6 is fixedly connected to the top of the U-shaped frame 7.

[0028] Specifically, the support plate 2 serves as an intermediate connecting structure, connecting the receiving plate 3 and the base 1 into a whole, enhancing the stability of the entire equipment structure, ensuring that the receiving plate 3 can withstand the weight of components such as the upper hydraulic rod 6 and various forces generated during operation, and guaranteeing the stability and reliability of the equipment during operation.

[0029] Working principle: In use, first, the hollow card plate 15 is taken out of the placement box 14, the automotive terminal is placed in the placement box 14, and the automotive terminal is placed on the upper surface of the hollow card plate 15. Then, during use, the reciprocating tilting mechanism can realize the dynamic immersion of the workpiece during the electroplating process to ensure the uniformity of the plating layer. First, the hydraulic rod 6 is used. The power source of the hydraulic rod 6 mainly relies on the interaction of the closed high-pressure gas nitrogen and hydraulic oil inside it. It can achieve self-drive without external power input. The hydraulic rod 6 drives the U-shaped frame 7 to rise vertically along the guide rod 18. The U-shaped frame 8 and the terminals in the placement box 14 are lowered and immersed in the electroplating bath 4. When the U-shaped frame 7 descends, the gears 10 and 13 fixed at both ends of the connecting rod 9 mesh with the high rack 11 and the low rack 12 respectively. Due to the difference in installation height between the racks 11 and 12, the racks 11 and 12 are forced to rotate. This causes the U-shaped frame 8 and the placement box 14 to swing back and forth through the connecting rod 9, causing the terminals in the placement box 14 to tilt left and right, thereby agitating the electroplating solution and eliminating bubbles, while promoting the uniform deposition of metal ions.
