Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular to an auxiliary guiding structure for an electroplating sub-tank. Background Technology

[0002] Continuous electroplating is a process of depositing a metal coating on the surface of a continuously moving substrate using electrochemical methods to improve the substrate's metallic properties. During continuous electroplating, the stable orientation of the substrate is crucial for ensuring coating uniformity and reducing mechanical damage.

[0003] Currently, the process of the substrate passing through the plating tank is guided by an independent guiding device. Usually, the guide seat is a metal guide roller or a fixed guide block. This method is prone to lateral displacement when the substrate tension changes. Existing guiding devices are difficult to dynamically compensate for this, which causes friction between the substrate and the overflow port, resulting in damage to the plating layer. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] The following is in conjunction with the appendix Figures 1 to 4To further describe, this utility model discloses an auxiliary guiding structure for an electroplating sub-tank, including a tank body 1 and a first anode plate 2 and a second anode plate 3 disposed within the tank body 1. The first anode plate 2 and the second anode plate 3 are disposed on both sides inside the tank body 1, and are respectively connected to the side walls on both sides of the tank body 1. Overflow ports 10 are provided at both ends of the tank body 1, and guide tubes 4 are provided at both ends of the overflow ports 10. The guide tubes 4 are provided with a clamping port 40, and the guide tubes 4 guide the plate through the clamping port 40. The tank wall panels on both sides of the overflow port 10 are fixed to the edge of the overflow port 10 by the deformation of the guide tubes 4. During electroplating, when the substrate 6 passes through the overflow ports 10 at both ends of the tank 1, it passes between the two guide tubes 4 to prevent the substrate 6 from changing tension. When lateral displacement occurs, it can protect the electroplating surface of the substrate 6 to a certain extent. In addition, under the restriction of the guide tubes 4 at both ends, the width of the overflow port 10 is tightened, which relatively reduces the flow rate of the electroplating solution, thereby allowing the stirring of the electroplating solution to be adjusted.

[0026] In a preferred embodiment, a bottom plate 11 is provided inside the tank 1, and fixed connecting blocks 12 extending into the tank 1 are provided on both sides of the tank 1. Each fixed connecting block 12 is provided with a screw hole.

[0027] In a preferred embodiment, there are four fixed connecting blocks 12, which are distributed in pairs on both sides of the tank 1. The fixed connecting blocks 12 are adapted to the connecting lugs 20 on the first anode plate 2 and the second anode plate 3 respectively.

[0028] In a preferred embodiment, the upper end of the first anode plate 2 is provided with a connecting lug 20 with a through hole. There are two connecting lugs 20. The connecting lugs 20 rest on the fixed connecting block 12 and are connected to the screw holes on the fixed connecting block 12 by inserting a hand screw 5 into the through hole, so as to fix the first anode plate 2 on both sides of the tank body 1. The second anode plate 3 is installed in the same way as the first anode plate 2.

[0029] In a preferred embodiment, the upper end of the first anode plate 2 is also provided with a handle 21 and a conductive connecting block 22. The conductive connecting block 22 is located adjacent to the handle 21, the handle 21 is located between two connecting lugs 20, and the conductive connecting block 22 is located between the handle 21 and the connecting lugs 20. In addition, the upper end of the conductive connecting block 22 is also provided with an upwardly protruding electrical contact post 23.

[0030] In a preferred embodiment, the guide tube 4 is inserted into and fixedly clamped on the edge of the overflow port 10 through the clamping port 40. In addition, when the guide tube 4 is inserted into the edge of the overflow port 10 through the clamping port 40, it is also screwed into and fixed on the edge of the overflow port 10 by a plastic screw.

[0031] In a preferred embodiment, the first anode plate 2 and the second anode plate 3 have the same structure.

[0032] In a preferred embodiment, the guide tube 4 is made of PEEK material. PEEK has better wear resistance than metal in acids, alkalis or solvents and has excellent wear resistance and high temperature resistance.

[0033] In summary, by installing guide tubes at the overflow ports at both ends of the tank, the guide tubes can assist in guiding the substrate passing through during continuous electroplating. Furthermore, they can protect the surface of the substrate when the substrate tension changes and lateral displacement occurs, thus preventing damage to the coating caused by friction between the substrate and the overflow port.

[0034] Although embodiments of the present invention have been shown above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make modifications and variations to the above embodiments, but such modifications are all included within the broad scope of the foregoing disclosure, drawings and claims.
