Technical Field

[0001] This utility model relates to the field of electroplating tank technology, specifically an electroplating tank for electroplating conductive terminals. Background Technology

[0002] In today's industrial production, electroplating of conductive terminals is a crucial process. Therefore, electroplating tanks are an indispensable piece of equipment in the production of conductive terminals.

[0003] Existing electroplating tanks have complex structures and unreasonable designs. Furthermore, electroplating tanks typically use a single inlet pipe installed on the side wall to achieve solution circulation. This method is prone to creating flow dead zones, resulting in differences in solution composition, temperature, and additive concentration in different areas of the tank. Consequently, this leads to uneven plating thickness at different parts of the terminal. To address this problem, the inventors designed an electroplating tank for electroplating conductive terminals. Utility Model Content

There are four sets of installation pipes, which are evenly distributed along the length of the connecting pipe. The conveying pipe is inserted into the outside of any set of installation pipes and is L-shaped. The installation component is located between the installation pipe and the conveying pipe.

[0006] Preferably, the mounting component includes a mounting groove, a rubber ring, and a fixing plate. The mounting groove is formed inside the top end of the conveying pipe. The rubber ring is fixed to the inner wall of the conveying pipe through the mounting groove. The fixing plate is fixed to the outer wall of the conveying pipe. Four sets of fixing plates are provided on the outer wall of one set of the conveying pipe.

[0007] Preferably, the fixing plate includes an arc-shaped plate and a horizontal plate, which are integrally formed.

[0008] Preferably, positioning plates are fixed on both sides of the outer wall of the mounting tube, the positioning plates are located inside the mounting groove, and the surface of the positioning plates is in contact with the surface of the rubber ring.

[0019] Please see Figures 1 to 5The present invention provides an embodiment of an electroplating tank for electroplating conductive terminals, the electroplating tank including a mother tank 1, a daughter tank 2 and a conveying assembly 5, the daughter tank 2 being disposed inside the mother tank 1 and the conveying assembly 5 being located on one side of the daughter tank 2. The conveying assembly 5 includes a fixed pipe 51, a connecting pipe 52, an installation pipe 53, a conveying pipe 54, and an installation component 55. The fixed pipe 51 is inserted into the interior of the sub-trough 2 and is located at the top of the central axis of the sub-trough 2. The connecting pipe 52 is fixed to one side of the fixed pipe 51 and is perpendicular to the fixed pipe 51. The installation pipe 53 is fixed to the side of the connecting pipe 52 away from the fixed pipe 51. There are four sets of installation pipes 53, and the installation pipes 53 are evenly distributed along the length of the connecting pipe 52. The conveying pipe 54 is inserted into the outside of any set of installation pipes 53 and is L-shaped. The installation component 55 is disposed between the installation pipe 53 and the conveying pipe 54.

[0020] The mother tank 1 is the main tank body, supporting the sub-tank 2, and is the basic container for the entire electroplating process. The mother tank 1 is the core area where the electroplating reaction occurs. The fixed pipe 51 firmly fixes the conveying component 5 to the sub-tank 2. The connecting pipe 52 horizontally connects the fixed pipe 51 and each mounting pipe 53, serving as the main pipeline to distribute the electroplating solution to each branch. The mounting pipe 53 serves as the fixed base for the conveying pipe 54. By being evenly distributed on the connecting pipe 52, it provides installation positions for multiple liquid distribution points. The conveying pipe 54 promotes the circulation of the solution from bottom to top in the entire sub-tank 2, avoiding short circuits and dead zones on the liquid surface, and ensuring the extreme uniformity of solution composition and temperature.

[0021] Mounting component 55 includes mounting groove 551, rubber ring 552 and fixing plate 553. Mounting groove 551 is opened inside the top end of conveying pipe 54. Rubber ring 552 is fixed to the inner wall of conveying pipe 54 through mounting groove 551. Fixing plate 553 is fixed to the outer wall of conveying pipe 54. Four sets of fixing plates 553 are provided on the outer wall of a set of conveying pipes 54.

[0022] The mounting groove 551 provides installation space for the rubber ring 552 and the positioning plate 554. The rubber ring 552 plays a sealing role to prevent the solution from leaking out. The delivery pipe 54 is fixed to the outside of the mounting pipe 53 by the connection of two sets of fixing plates 553 and fixing blocks 556 in the vertical direction.

[0023] The fixing plate 553 includes an arc plate 5531 and a horizontal plate 5532, which are integrally formed.

[0024] The curved plate 5531 fits against the pipe wall to provide structural strength, while the horizontal plate 5532 facilitates connection with the screw 555.

[0025] Positioning plates 554 are fixed on both sides of the outer wall of the mounting tube 53. The positioning plates 554 are located inside the mounting groove 551, and the surface of the positioning plates 554 is in contact with the surface of the rubber ring 552.

[0026] Positioning plate 554 ensures the accuracy of the connection position between delivery pipe 54 and installation pipe 53, and guarantees the tightness of the connection.

[0027] A fixing block 556 is fixed to the outer wall of the positioning plate 554. The fixing block 556 is located between two sets of horizontal plates 5532 in a vertical direction. A screw 555 is threaded between the horizontal plate 5532 and the fixing block 556. The screw 555 passes through the fixing block 556 from the top horizontal plate 5532, and the bottom end of the screw 555 is located inside the bottom horizontal plate 5532.

[0028] The fixing block 556 provides a lateral connection point, and the screw 555 connects and fixes the fixing plate 553 and the positioning plate 554, thereby stably connecting the conveying pipe 54 and the installation pipe 53 together.

[0029] The mother groove 1 has through grooves 3 on both sides. The through grooves 3 are symmetrically distributed with reference to the central axis of the mother groove 1, and the through grooves 3 are square in shape.

[0030] The through groove 3 facilitates the entry of conductive terminals into the mother groove 1, providing a channel for the conductive terminals to enter and exit the mother groove 1 and reach the daughter groove 2 for electroplating operations.

[0031] The two sides of the sub-slot 2 are fitted with regulating pipes 4. There are four sets of regulating pipes 4 in total. Two sets of regulating pipes 4 are set on one side of the sub-slot 2. There is a gap between the regulating pipes 4.

[0032] The regulating tube 4 is snapped onto both sides of the sub-slot 2 to serve as a guide. The gap between the regulating tubes 4 cooperates with the through slot 3 on the mother slot 1 to form a channel for the conductive terminal to enter the sub-slot 2.

[0033] Working principle: When electroplating is required, the conductive terminals enter the sub-tank 2 through the gap between the through groove 3 and the regulating tube 4. The solution inside the sub-tank 2 performs the electroplating operation on the guide terminals. The solution is continuously delivered into the sub-tank 2 through the set delivery component 5. Due to the design of the delivery tube 54, the solution can be delivered into the sub-tank 2 quickly and evenly. When the delivery tube 54 is aged and damaged, a rotational force is applied to the screw 555 to remove the screw 555 from the inside of the fixing plate 553. Then, a pulling force is applied to the delivery tube 54 to pull the delivery tube 54 out from the outside of the mounting tube 53. Then, a new delivery tube 54 is inserted into the outside of the mounting tube 53 so that the positioning plate 554 abuts against the surface of the rubber ring 552. Finally, the screw 555 is turned into the inside of the horizontal plate 5532 and the fixing block 556.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
