Description

Technical Field

[0001] This utility model relates to the technical field of electroplating, specifically to a double-sided electroplating wire clamp segmented misalignment clamping device. Background Technology

[0002] Current double-clamp electroplating lines have significant technical limitations: the clamping point position of the clamp remains fixed from the moment the workpiece enters the tank until it exits, which directly makes it difficult to increase the current density. Because the clamping point position is unchanged, the electroplating effect in the contact area between the workpiece and the clamp is limited by the initial current setting. Blindly increasing the current can easily lead to quality problems such as local overplating, which in turn prevents the electroplating time from being shortened, ultimately resulting in low production efficiency and difficulty in breaking through production capacity. Utility Model Content

[0003] Based on the above description, this utility model provides a segmented staggered clamping device for double-sided electroplating line clamps. By gradually increasing the current density in subsequent tanks according to the electroplating effect of the previous sequence, the electroplating time of a single workpiece is significantly shortened while ensuring electroplating quality, thereby significantly improving the production line speed and achieving a leap in production efficiency.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A double-sided clamping electroplating line clamp segmented staggered clamping device includes a product line to be electroplated, at least two steel strip groups, and a power supply device corresponding to each of the steel strip groups; the steel strip groups are arranged sequentially along the conveying direction of the product line to be electroplated. Each of the steel strip groups includes a first steel strip and a second steel strip symmetrically arranged on both sides of the product conveying line to be electroplated, and electroplating clips for connecting the products to be electroplated are respectively provided on the first steel strip and the second steel strip. The power supply device is connected to the corresponding first steel strip and the second steel strip respectively, and is used to supply power to the product to be electroplated through the electroplating clamp on the corresponding steel strip group; along the conveying direction of the product to be electroplated line, the current density provided by the power supply device gradually increases.

[0005] Based on the above technical solution, the present invention can be further improved as follows.

[0006] Furthermore, the electroplating clamps on the steel strip assembly form corresponding clamping positions at their contact points with the product to be electroplated, and the corresponding clamping positions on the product to be electroplated are alternately arranged for every two adjacent steel strip assemblies.

[0008] Furthermore, a first chain and a second chain are provided between every two adjacent steel strip groups; One end of the first chain is connected to the first driven wheel of the steel strip group on the front side of the conveying direction of the product to be electroplated, and the other end of the first chain is connected to the first drive wheel of the steel strip group on the rear side of the conveying direction of the product to be electroplated. One end of the second chain is connected to the second driven wheel of the steel strip group on the front side of the conveying direction of the product to be electroplated, and the other end of the second chain is connected to the second drive wheel of the steel strip group on the rear side of the conveying direction of the product to be electroplated.

The two ends of the pressure strips are connected to the first frame and the second frame, respectively. The pressure strips are used to press down on the limiting rod.

[0012] Furthermore, a roller is provided at the top of the limiting rod, and the roller is used to roll in cooperation with the pressure strip.

[0018] A segmented staggered clamping device for a double-sided electroplating line clamp includes a product line 1 to be electroplated, at least two steel strip groups 3, and a power supply device 4 corresponding to each steel strip group 3. The steel strip groups 3 are arranged sequentially along the conveying direction of the product line 1 to be electroplated.

[0019] Specifically, each steel strip group 3 includes a first steel strip 31 and a second steel strip 32 symmetrically arranged on both sides of the conveyor line of the product to be electroplated 2. Electroplating clips 35 for connecting the product to be electroplated 2 are respectively provided on the first steel strip 31 and the second steel strip 32.

[0020] In addition, each steel strip group 3 includes a first frame 33 and a second frame 34.

[0021] One end of the first steel belt 31 is connected to the first frame 33 via the first drive wheel, and the other end of the first steel belt 31 is connected to the second frame 34 via the first driven wheel.

[0022] One end of the second steel belt 32 is connected to the first frame 33 via the second drive wheel, and the other end of the second steel belt 32 is connected to the second frame 34 via the second driven wheel.

[0023] A first chain 8 and a second chain 9 are provided between every two adjacent steel strip groups 3.

[0024] One end of the first chain 8 is connected to the first driven wheel of the steel belt group 3 on the front side of the conveying direction of the product line 1 to be electroplated, and the other end of the first chain 8 is connected to the first drive wheel of the steel belt group 3 on the rear side of the conveying direction of the product line 1 to be electroplated.

[0025] One end of the second chain 9 is connected to the second driven wheel of the steel belt group 3 on the front side of the conveying direction of the product line 1 to be electroplated, and the other end of the second chain 9 is connected to the second drive wheel of the steel belt group 3 on the rear side of the conveying direction of the product line 1 to be electroplated.

[0026] A gearbox 7 is installed on the top of the first frame 33 of the steel belt group 3 at the front of the conveying direction of the product line 1 to be electroplated, and the first drive wheel and the second drive wheel are connected through the gearbox 7.

[0027] By setting up the first chain 8, the second chain 9, and the gearbox 7, the rotation of the first steel belt 31 and the second steel belt 32 in each steel belt group 3 can be kept synchronized.

[0028] The clamping device in this embodiment also includes a drive motor 5, which is connected to the first drive wheel of the steel strip group 3 at the foremost side of the conveying direction along the product line 1 to be electroplated via a reducer 6.

[0029] In this embodiment, the electroplating clamp 35 includes a fixed clamp 351 and a movable clamp 352, with the movable clamp 352 disposed above the fixed clamp 351. A limit rod 353 is connected to the upper side of the movable clamp 352. Limiting blocks 354, corresponding one-to-one with the limit rods 353, are provided on the first steel strip 31 and the second steel strip 32. The limit rods 353 and the corresponding limit blocks 354 are elastically connected and can slide up and down.

[0030] Both the first steel strip 31 and the second steel strip 32 have pressure strips 36 on their top sides near the product line 1 to be electroplated. The two ends of the pressure strips 36 are connected to the first frame 33 and the second frame 34, respectively. The top of the limiting rod 353 is equipped with a roller 355, which is used to roll in cooperation with the pressure strips 36. The pressure strips 36 are used to press the limiting rod 353 downward, so that the fixed clamp 351 and the movable clamp 352 can automatically clamp the product 2 to be electroplated.

[0031] In addition, the electroplating clips 35 on the steel strip group 3 form corresponding clamping positions with the contact points of the product 2 to be electroplated, and the corresponding clamping positions on the product 2 of every two adjacent steel strip groups 3 are arranged alternately. Figure 5 As shown, in this embodiment, the product 2 to be electroplated is provided with alternating first clamping positions 21 and second clamping positions 22 on both sides. Each pair of adjacent steel strip groups 3 clamps the first clamping position 21 and the second clamping position 22 respectively, so that each clamping point acts precisely on the thickened area formed by the previous electroplating. This avoids direct clamping interference to the unplated area and utilizes the thickened copper layer as a stable conductive carrier, creating conditions for increasing the current density in the future.

[0032] Even better, each steel strip group 3 can be clamped at a different position from the other steel strip groups 3, with more clamping positions set on both sides of the product to be electroplated 2.

[0033] The power supply device 4 is connected to the corresponding first steel strip 31 and second steel strip 32 respectively, and is used to supply power to the product 2 to be electroplated through the electroplating clamp 35 on the corresponding steel strip group 3. Along the conveying direction of the product line 1 to be electroplated, the current density provided by the power supply device 37 gradually increases.

[0034] This embodiment significantly shortens the electroplating time of a single workpiece while ensuring electroplating quality by gradually increasing the current density in subsequent tanks based on the electroplating effect of the preceding tanks. This results in a significant increase in production line speed and a leap in production efficiency.
