Description

TECHNICAL FIELD

[0001] The utility model relates to electroplating technical field, concretely relates to a kind of walk with double edge electroplating clamp. BACKGROUND

[0002] With the development of electric vehicles, portable electronic devices and large-scale energy storage systems, the demand for high-performance batteries is increasing. As a key component connecting electrode materials and external circuits, the performance of the current collector has a significant impact on the efficiency, safety and life of the entire battery system. The current collector, as the core carrier of electron transport in the positive and negative materials of lithium-ion batteries, is an important part of the battery structure. Functional current collectors with a "metal-polymer material-metal" sandwich structure have shown significant potential in improving battery safety and energy density due to their unique structural advantages.

[0003] When plating a metal layer on a polymer material, common metal plating methods include chemical metal plating, electro-deposition metal plating, and other methods. Electro-deposition metal plating is widely used in industrial production due to its high efficiency. However, due to the thinness of the polymer material film and its susceptibility to minor environmental changes, the film is unevenly stressed during electroplating in the electroplating tank. Uneven stress on the film can cause wrinkles or even film rupture, affecting the performance and quality of the functional current collector prepared by the plated film. SUMMARY

[0004] The utility model aims at providing a kind of walk with double edge electroplating clamp, and solve the above problems by the design of electroplating clamp.

[0005] To achieve the above-mentioned purpose, the technical solution provided by the utility model is:

[0006] A walk with double edge electroplating clamp, comprising an upper roller, a lower roller and a pneumatic device;

[0007] The upper roller includes an upper outer ring roller and an upper roller shaft, and the outer ring roller and the upper roller shaft are rotatably connected within a limited range. The lower roller includes a lower outer ring roller and a lower roller shaft, and the outer ring roller and the lower roller shaft are rotatably connected within a limited range.

[0008] The roller surfaces of the upper outer ring roller of the upper roller and the lower outer ring roller of the lower roller are opposite to each other, and the two roller surfaces form an electroplating clamping gap.

[0009] The upper roller shaft is connected and fixed to the upper support arm, the lower roller shaft is connected and fixed to the lower support arm, one of the upper support arm and the lower support arm is connected to the pneumatic device, and the pneumatic device is used to control the opening and closing of the upper support arm and the lower support arm.

[0010] To optimize the above technical solutions, the specific measures taken also include:

[0011] Further, the buffer limiting block is provided between the upper support arm and the lower support arm, and the buffer limiting block is an elastic component, one end of the buffer limiting block being fixedly connected with the upper support arm or the lower support arm.

[0012] Further, the structure of the upper roller shaft and the lower roller shaft is as follows:

[0013] The roller shaft includes a roller shaft shell and a roller shaft core, the end of the roller shaft core being inserted into the roller shaft shell, the inner side of the roller shaft shell being provided with a plurality of spaced limiting blocks, and a plurality of fan blades being radially connected to the roller shaft core, each fan blade being arranged between two adjacent limiting blocks so that the rotation of the fan blade is limited in the space between the two adjacent limiting blocks.

[0014] Further, the side of the roller shaft shell is provided with a baffle, the baffle being provided with a hole in the center, the end of the roller shaft core being enlarged and limited by the baffle, and the shaft body of the roller shaft core penetrating through the hole in the center of the baffle.

[0015] The pneumatic device includes a pneumatic element, a connecting air pipe and a pneumatic electromagnetic valve, the movable end of the pneumatic element being connected with one of the upper support arm and the lower support arm, the connecting air pipe connecting the pneumatic element with the pneumatic electromagnetic valve, and the other support arm not connected with the pneumatic device being connected with the fixed end of the pneumatic element.

[0018] The plurality of belt running double-side electroplating clamps arranged in parallel are arranged on a movable device, and are used to make the belt running double-side electroplating clamps and the thin film to be electroplated clamped thereby translate synchronously.

[0019] The plurality of belt running double-side electroplating clamps arranged in parallel include two groups, and are arranged on the left side and the right side of the thin film to be electroplated respectively.

[0020] The left group of belt running double-side electroplating clamps and the right group of belt running double-side electroplating clamps move at the same speed and in the same direction.

[0021] Compared with the prior art, the utility model has the beneficial effects that:

[0022] This invention utilizes the coordinated use of rollers between the upper and lower support arms of a double-sided electroplating clamp. When electroplating a thin film is required, a solenoid valve causes the upper and lower rollers to clamp the film. This ensures that during the electroplating process, the contact points between the upper and lower clamps of the conductive clamp and the film move at the same speed ratio, guaranteeing that the contact points can achieve the coating processing, while preventing damage to the film caused by subsequent opening and closing of the conductive clamp. This invention can alleviate the unevenness of the film surface caused by uneven force during the thin film electroplating process, improve the quality of electroplated products, reduce the defect rate of functional current collectors made from this thin film, and achieve an overall improvement in quality.
