Description

Technical Field

[0001] The utility model belongs to the technical field of electroplating equipment, and in particular relates to a movable shielding plate of an electroplating production line. Background Art

[0002] The working principle of the electroplating production line is simply to provide low voltage and high current into the electroplating tank, with the parts to be plated as the cathode and the plated metal as the anode, forming metal ions that enter the electroplating solution, and then the metal ions move to the cathode under the action of the potential difference to form a coating.

[0003] When the electroplating production line is used to tin the matrix bridge stack and some components in photovoltaic equipment, the matrix bridge stack and photovoltaic components serving as the cathode only need to be electroplated in certain areas due to their own shape and process requirements. Excessive plating area will cause excessive consumption of tin balls and increase production costs. In addition, the plating thickness of the parts that need to be plated is also uneven. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a movable shielding plate for an electroplating production line, which is used to solve the technical problems in the existing technology that the parts to be plated consume too much plating metal, resulting in increased costs, and uneven plating thickness of the plated parts.

[0005] The utility model solves the above-mentioned technical problem with the following technical solution: a movable shielding plate of an electroplating production line, wherein the electroplating production line is composed of a plurality of electroplating tanks connected together, including:

[0006] The electroplating tank includes a hanging chain in the middle and two solder ball bags on both sides of the hanging chain;

[0007] Two shielding plates, the two shielding plates are located parallel to each other on both sides of the hanging chain and between the solder ball bags;

[0008] A lifting mechanism is provided in the electroplating tank and is connected to the two shielding plates at the same time.

[0009] The utility model arranges a shielding plate in the electroplating tank, and raises or lowers the position of the shielding plate by a lifting mechanism so that the shielding plate corresponds to the position of the workpiece to be plated where plating is not required, or the position where the plating thickness is too thick. The shielding plate is non-conductive, which can reduce the current density in the area where the shielding plate is located, thereby slowing down the plating deposition speed, thereby achieving the purpose of preventing or reducing the deposition of the plating in the corresponding area, and achieving the purpose of controlling the plating range and the plating thickness.

[0010] Furthermore, the lifting mechanism includes two sets of drive components, and the drive components include:

[0011] a driving rod, which is arranged at one end of the electroplating tank and transversely penetrates the electroplating tank;

[0012] a connecting rod, which is sleeved on the driving rod;

[0013] a connecting block, one end of which is fixedly connected with the shielding plate, and the other end of which is hingedly connected with the connecting rod.

[0014] The beneficial effects of the present step are that the driving rod is rotated to drive the connecting rod to rotate, the connecting rod drives the connecting block to move up or down, and the purpose of adjusting the shielding plate to move up or down is finally achieved.

[0015] Further, the end of the driving rod extending out of the electroplating tank is provided with a crank handle.

[0016] The beneficial effects of the present step are that the crank handle can show the rotation amplitude of the driving rod, and the electroplating tank does not need to be opened for observation.

[0017] Further, the outer wall of the electroplating tank is provided with an arc-shaped limiting block corresponding to the position of the crank handle.

[0018] A plurality of limiting holes are formed in the arc-shaped limiting block.

[0019] The end of the crank handle is provided with an elastic limiting pin corresponding to the limiting hole.

[0020] The beneficial effects of the present step are that the position of the crank handle is limited by the arc-shaped limiting block, and the purpose of fixing the position of the shielding plate is achieved.

[0021] Further, the connecting rod and the connecting block are made of aluminum alloy, and the surfaces of the connecting rod and the connecting block are provided with an anodized layer.

[0022] The beneficial effects of the present step are that the aluminum alloy material with the anodized layer is insulating and does not participate in electroplating.

[0023] Further, the shielding plate is made of insulating material.

[0024] The beneficial effects of the present step are that the insulating material can shield the current, thereby achieving the purpose of affecting the thickness and range of the plated layer.

[0025] The beneficial effects of the present utility model are:

[0026] 1. The present utility model can control the shielding plate to move up or down, so that the shielding plate can cover the parts to be plated without electroplating, or the area where the thickness of the plated layer needs to be controlled. In this way, the electroplating area and the thickness of the plated layer can be controlled by reducing the current density, which not only meets the electroplating requirements, but also achieves cost control.

[0027] 2. The arc-shaped limit plate and elastic limit pin in the lifting mechanism cooperate to limit the crank, allowing the shielding plate to automatically maintain the shielding state for a long time and maintain the preset electroplating effect for a long time without manual intervention.

[0048] The shielding plate 4 is arranged in the electroplating tank 1, the position of the shielding plate 4 is lifted or lowered through the lifting mechanism 5, so that the shielding plate 4 is not conductive at the position corresponding to the position of the parts to be plated 8 which does not need plating layer or the position of the plating layer with excessive thickness, the current density of the electroplating liquid in the area where the shielding plate 4 is arranged is reduced, so that the plating layer deposition speed is slowed down, the purpose that the plating layer in the corresponding area cannot be deposited or the deposition is reduced is achieved, the purpose that the plating layer range and the plating layer thickness are controlled is achieved, and finally the cost control is realized.

[0049] On the basis of the above technical scheme, the lifting mechanism 5 comprises two groups of driving assemblies, and the driving assembly comprises:

[0050] A driving rod 51 is arranged at one end of the electroplating tank 1, and the driving rod 51 penetrates the electroplating tank 1 transversely;

[0051] A connecting rod 52 is sleeved on the driving rod 51, and the end of the connecting rod 52 sleeved on the driving rod 51 is provided with an opening, and the opening can be locked through a bolt, so that the position and the deflection angle of the connecting rod 52 on the driving rod 51 are conveniently adjusted;

[0052] A connecting block 53 is fixedly connected with the shielding plate 4 at one end, and the other end of the connecting block 53 is hingedly connected with the connecting rod 52.

[0053] Through the rotation of the driving rod 51, the connecting rod 52 is driven to rotate, and the connecting rod 52 drives the connecting block 53 to move upward or downward, so that the purpose that the shielding plate 4 moves upward or downward is finally achieved.

[0054] On the basis of the above technical scheme, the end of the driving rod 51 extending out of the electroplating tank 1 is provided with a crank 6.

[0055] In order that the crank 6 can clearly show the rotation amplitude of the driving rod 51, when the crank 6 is installed on the driving rod 51, the angle of the crank 6 needs to be adjusted, so that the deflection angle of the crank 6 and the connecting rod 52 is the same, so that the deflection angle of the connecting rod 52 can be observed without opening the cover plate of the electroplating tank 1, and the height of the shielding plate 4 can be accurately inferred.

[0056] As Figure 3 And Figure 4 As shown in the figure, the outer wall of the electroplating tank 1 is provided with an arc-shaped limiting block 7, which corresponds to the position of the crank 6;
