[0002] Terminal strip electroplating refers to the process of electroplating the terminal strip during the manufacturing process of electronic components. The terminal strip usually refers to the pin part of the connector, and electroplating is to improve its performance and appearance. The electroplating process of the terminal strip generally includes: cleaning, before electroplating, the terminal strip needs to be thoroughly cleaned to remove oil, oxides and other impurities on the surface. This usually includes steps such as degreasing, pickling and water washing; pre-treatment, depending on the material to be electroplated, different pre-treatment processes may be required, such as activation and pre-plating, to ensure the adhesion of the electroplating layer; electroplating, immersing the cleaned terminal strip in the electroplating solution, and passing the current to deposit the electroplating material on the terminal surface to form a uniform electroplating layer. Common electroplating materials include gold, silver, nickel, tin, etc.; post-treatment, after the electroplating is completed, the terminal strip needs to be post-processed, such as water washing, passivation and drying, to remove the residual electroplating solution and increase the stability and durability of the electroplating layer. In the continuous electroplating process of the terminal strip, the terminal strip is assisted by the spot plating wheel during the conveying process.

[0003] In the prior art, when the terminal strip passes through the spot plating wheel, the positioning holes on the strip cooperate with the positioning protrusions on the surface of the spot plating wheel to achieve the strip positioning while facilitating the terminal strip to drive the spot plating wheel to rotate, thereby completing the electroplating process of the terminal strip. That is, in this process, the spot plating wheel is a driven wheel. However, for thinner terminal strips, in the process of driving the spot plating wheel to rotate, the positioning holes of the strip are easily deformed by the reaction force of the spot plating wheel, which leads to the scrapping of batches of terminals.

[0027] See also Figures 1 to 3The utility model discloses an electroplating line auxiliary driving mechanism 10, which includes a trough body 100, a mounting seat 200, a driving unit 300 and a spot plating wheel 400. The trough body 100 is arranged in an adapted electroplating line for the terminal strip to complete the electroplating process; the mounting seat 200 is arranged inside the trough body 100; the spot plating wheel 400 is rotatably installed in the mounting seat 200; the driving unit 300 is arranged outside the trough body 100, and the driving end of the driving unit 300 penetrates the side wall of the trough body 100 and the mounting seat 200, and then, the driving end of the driving unit 300 drives the connection spot plating wheel 400. In actual application, the adapted terminal strip passes through one end of the trough body 100 to the other end of the trough body 100. In this process, the terminal strip corresponds to the surface of the spot plating wheel 400, so that the surface of the terminal strip is positioned and connected to the surface of the spot plating wheel 400. In the traditional terminal strip electroplating line, the spot plating wheel 400 is a driven wheel relative to the terminal strip, that is, during the transmission of the terminal strip, the spot plating wheel 400 is driven to rotate. However, since the positioning holes on the surface of the terminal strip cooperate with the positioning protrusions on the surface of the spot plating wheel 400, the spot plating wheel 400 is driven. Rotation; Based on this, for thinner terminal strips, the reaction force driven by the spot plating wheel 400 is likely to cause deformation of the terminal strip, thereby causing batch scrapping of terminals; In this regard, the electroplating line auxiliary drive mechanism 10 of the utility model drives the spot plating wheel 400 to actively rotate through the drive unit 300, thereby cooperating with the terminal strip during the conveying process to achieve auxiliary drive, thereby reducing the action and reaction forces between the spot plating wheel 400 and the terminal strip, and then effectively avoiding deformation and damage of the terminal strip during the electroplating process, greatly improving the terminal product yield. In one embodiment, the drive unit 300 is configured as a motor, and the output shaft of the motor passes through the side wall of the slot body 100 and the mounting seat 200 and drives the connection spot plating wheel 400 to drive the spot plating wheel 400 to actively rotate in accordance with the conveying speed of the terminal strip.

[0028] Furthermore, the electroplating line auxiliary drive mechanism 10 also includes a buffer wheel 500, which is arranged on the downstream side of the spot plating wheel 400 along the conveying direction of the terminal material strip. The terminal material strip is wound on the surface of the buffer wheel 500 after being assisted by the spot plating wheel 400, so that the buffer wheel 500 can adjust the conveying direction of the terminal material strip. At the same time, the buffer wheel 500 can respond according to the conveying speed of the downstream end of the terminal material strip, and feed back to the drive unit 300, prompting the drive unit 300 to adjust the output power, and then adjust the rotation speed of the spot plating wheel 400, so as to ensure the speed matching between the spot plating wheel 400 and the terminal material strip. Specifically, the buffer wheel 500 is connected to the mounting seat 200 and the side wall of the tank body 100 in sequence and swings through a connecting rod mechanism 510, that is, the connecting rod mechanism 510 extends from the inside of the tank body 100 to the outside of the tank body 100, and when the main body of the connecting rod mechanism 510 rotates, the buffer wheel 500 swings around the rotation axis of the connecting rod mechanism 510 as the axis; the connecting rod mechanism 510 is connected to a counterweight 520 and an angle sensor (not shown), so that when the rotation speed of the spot plating wheel 400 is greater than the conveying speed of the terminal strip, the downstream side of the spot plating wheel 400, that is, the terminal strip between the spot plating wheel 400 and the buffer wheel 500 is in a relaxed state; at this time, under the counterweight 520 Under the action, the connecting rod mechanism 510 rotates, causing the buffer wheel 500 to swing and deviate from a certain angle, so as to stretch the terminal strip between the spot plating wheel 400 and the buffer wheel 500 to a preset tension; in this process, the angle sensor detects the rotation angle of the connecting rod mechanism 510, that is, the swing angle of the buffer wheel 500, and feeds back to the control end of the electroplating line, so as to judge the speed difference between the rotation speed of the spot plating wheel 400 and the conveying speed of the terminal strip, and then adjusts the output power of the drive unit 300 to slow down until the buffer wheel 500 swings back and resets to the preset angle, thus achieving consistency adjustment between the rotation speed of the spot plating wheel 400 and the conveying speed of the terminal strip. Based on the above-mentioned spot plating wheel 400 speed adjustment process, when the rotation speed of the spot plating wheel 400 is less than the conveying speed of the terminal strip, the speed adjustment method of the spot plating wheel 400 is the same as the principle of the above-mentioned process, which will not be repeated here. In one embodiment, the electroplating line auxiliary drive mechanism 10 may also be provided with a plurality of speed sensors on the downstream side of the spot plating wheel 400 to detect the conveying speed of the terminal strip and feed back to the control end, so as to adjust the rotation speed of the spot plating wheel 400 accordingly.

[0029] Furthermore, the electroplating line auxiliary drive mechanism 10 also includes a transmission component 600, the input end of the transmission component 600 is connected to the driving end of the driving unit 300; the output end of the transmission component 600 drives the connection point plating wheel 400. Specifically, the transmission assembly 600 includes a first gear shaft 610, a first gear 620, a second gear shaft 630, a second gear 640 and a spot plating wheel fixing plate 650, one end of the first gear shaft 610 is connected to the driving end of the driving unit 300, and the other end of the first gear shaft 610 is drivingly connected to the first gear 620; the first gear 620 is arranged inside the mounting seat 200; one end of the second gear shaft 630 is connected to the side wall of the trough body 100, and the other end of the second gear shaft 630 extends through to the inside of the mounting seat 200; the second gear 640 is arranged inside the mounting seat 200, the second gear 640 is sleeved on the end of the second gear shaft 630, and the second gear 640 is meshed with the first gear 620; one side of the spot plating wheel fixing plate 650 is connected to the side surface of the second gear 640, and the other side of the spot plating wheel fixing plate 650 is connected to the spot plating wheel 400. In actual operation, the driving unit 300 drives the first gear 620 to rotate through the first gear shaft 610, and the first gear 620 drives the second gear 640 to rotate, thereby enabling the spot plating wheel 400 installed on the surface of the spot plating wheel fixing plate 650 to actively rotate at a preset speed. In one embodiment, the second gear 640 is fixedly connected to the spot plating wheel fixing plate 650 through a plurality of connecting pins 641; in another embodiment, the spot plating wheel 400 can also be driven and connected to the driving end of the driving unit 300 through a driving shaft, so that the driving unit 300 directly drives the spot plating wheel 400.

[0030] Furthermore, the electroplating line auxiliary drive mechanism 10 also includes a plurality of supporting wheels 700, which are respectively arranged on the outer periphery of the spot plating wheel 400, and each supporting wheel 700 is installed and connected to the mounting seat 200; the side surface of each supporting wheel 700 cooperates and abuts with the side surface of the spot plating wheel 400, thereby supporting the spot plating wheel 400, thereby reducing the jumping or swinging of the spot plating wheel 400 during operation and improving the rotation stability of the spot plating wheel 400.

[0031] Furthermore, the electroplating line auxiliary drive mechanism 10 is also provided with a plurality of material feed guide wheels 800, which are respectively installed and connected in the mounting seat 200 to cooperate with the spot plating wheel 400 and the buffer wheel 500 to transport the terminal material strip, thereby improving the transportation and processing stability of the terminal material strip.

[0032] To sum up, the electroplating line auxiliary driving mechanism disclosed by the utility model will pass the adapted terminal strip from one end of the slot body to the other end of the slot body. During this process, the terminal strip corresponds to the surface of the spot plating wheel, so that the surface of the terminal strip is positioned and connected to the surface of the spot plating wheel; for the terminal strip with a thinner thickness, the reaction force exerted on the spot plating wheel by driving it can easily cause the terminal strip to deform, thereby causing batches of terminals to be scrapped; in this regard, the electroplating line auxiliary driving mechanism of the utility model drives the spot plating wheel to actively rotate through the driving unit, thereby cooperating with the terminal strip in the conveying process to realize auxiliary driving, thereby reducing the action and reaction force between the spot plating wheel and the terminal strip, and then effectively avoiding deformation and damage of the terminal strip during the electroplating process, greatly improving the terminal product yield.
