A conductive fixture for preventing material from jumping

Abstract

A conductive jig for preventing material from jumping includes a fixed bottom plate and a conductive wheel. The fixed bottom plate also includes a guide wheel arranged in parallel with the conductive wheel and an anti-jumping assembly for pressing a strip of material. A gap for the strip of material to pass through is formed between the guide wheel and the conductive wheel. The anti-jumping assembly and the guide wheel are arranged on both sides of the strip of material relative to each other. The anti-jumping assembly includes a rotating shaft and an adjusting plate rotatably arranged on the rotating shaft. A material pressing block is arranged on the side of the adjusting plate away from the rotating shaft, and an elastic member is arranged on the other side. The anti-jumping assembly can make the strip of material have a movement tendency toward the side of the guide wheel, so that the strip of material can be located in the gap between the guide wheel and the conductive wheel, and the strip of material is prevented from jumping along the axis of the conductive wheel. The guide wheel and the anti-jumping assembly ensure that the strip of material is fully in contact with the conductive guide wheel, and the strip of material is prevented from deviating from the horizontal working position and poor contact, thereby ensuring that the surface of the strip of material can be evenly deposited.

Description

Technical Field

[0001] The invention relates to the technical field of electroplating, and in particular to a conductive fixture for preventing material jumping. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. Most electronic connectors and terminals need to be surface treated, generally electroplating, for two main reasons: 1. To protect the terminal spring substrate from corrosion; 2. To optimize the performance of the terminal surface, establish and maintain the contact interface between the terminals, especially the film layer control.

[0003] In order to realize continuous production of shells, terminals and plates, the above parts are produced in strip form during electroplating. In order to facilitate continuous electroplating, the strip material is usually transported by traction. The electroplated terminals in actual production are relatively long (the length in the electroplating machine reaches more than 50 meters). When the strip material is electroplated, it will cause the strip material to be difficult to fix, the working position is easy to deviate and the contact is poor, resulting in uneven deposition or no deposition on the surface of the strip material, which reduces work efficiency. There is room for improvement in the prior art. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes an anti-jumping material electroplating jig, which enables the strip material to maintain full contact with the conductive guide wheel through the anti-jumping material component, avoiding the strip material from deviating from the working position and poor contact, thereby ensuring that the surface of the strip material can be evenly deposited.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a conductive jig for preventing material from jumping, comprising a fixed base plate and a conductive wheel rotatably arranged on the fixed base plate, the fixed base plate also comprising a guide wheel arranged parallel to the conductive wheel and an anti-jumping component for pressing the strip material, a gap for the strip material to pass through is formed between the guide wheel and the conductive wheel, the anti-jumping component and the guide wheel are arranged on both sides of the strip material opposite to each other, the anti-jumping component comprises a rotating shaft and an adjusting plate rotatably arranged on the rotating shaft, a pressing block is arranged on one side of the adjusting plate away from the rotating shaft, and an elastic member is arranged on the other side to keep the pressing block in contact with the strip material.

[0006] By adopting the above technical scheme, the strip material is connected to the electrode through the conductive wheel and continuous feeding is achieved. The guide wheel ensures that the strip material can maintain contact with the conductive wheel during operation, thereby avoiding the strip material from deviating in the tangential direction of the conductive wheel during operation. The anti-jump material component can make the strip material have a movement tendency toward one side of the guide wheel, so that the strip material can be located in the gap between the guide wheel and the conductive wheel, thereby avoiding the strip material from jumping along the axis of the conductive wheel. The guide wheel and the anti-jump material component ensure that the strip material is fully in contact with the conductive guide wheel, thereby avoiding the strip material from deviating from the working position and poor contact, thereby ensuring that the surface of the strip material can be evenly deposited.

[0007] The present invention is further configured as follows: the rotating shaft penetrates the adjusting plate, the elastic member includes a torsion spring sleeved on the rotating shaft, one end of the torsion spring is fixedly connected to the adjusting plate, and the other end is provided with a knob rotatably connected to the rotating shaft.

[0008] By adopting the above technical solution, the torsion of the torsion spring can be adjusted by the knob, thereby adjusting the torsion of the adjustment plate on the rotating shaft, and then adjusting the pressure of the pressing block on the strip material, ensuring that the pressing block applies sufficient pressure to the strip material and does not cause deformation of the strip material due to excessive pressure.

[0009] The present invention is further configured such that: the knob is a rotating buckle handle.

[0010] By adopting the above technical solution, the buckle handle can be rotated to conveniently twist the torsion spring to adjust the torque of the torsion spring.

[0011] The present invention is further configured as follows: the pressing block includes a pressing shaft parallel to the rotating shaft, and a pressing wheel is arranged on the pressing shaft.

[0012] By adopting the above technical solution, rolling friction is achieved between the pressing block and the strip material, which reduces the friction between the pressing block and the strip material on the one hand, and can keep the strip material in a tight operating state through the pressing wheel on the other hand.

[0013] The present invention is further configured as follows: an annular groove for clamping the strip material is provided on the side surface of the pressing wheel.

[0014] By adopting the above technical solution, the annular groove formed on the pressing wheel can limit the displacement of the strip material in the axial direction of the pressing wheel, thereby ensuring that the strip material can maintain contact with the conductive wheel and ensure that the strip material runs with electricity.

[0015] The present invention is further configured as follows: the anti-jump material assembly also includes an adjustment plate arranged in the vertical direction, the adjustment plate itself has an adjustment slot in its length direction, the rotating shaft passes through the adjustment slot, and a fastening bolt is arranged at one end of the rotating shaft away from the knob.

[0016] By adopting the above technical solution, the anti-jump material assembly with an adjustment plate can be suitable for the transmission of strip materials of different heights. The position of the pressing block can be adjusted by adjusting the fixed position of the rotating shaft in the adjustment groove by tightening the bolt, which is convenient for users to adjust.

[0017] The present invention is further configured as follows: a first outer edge extends from the bottom surface of the conductive wheel, and the guide wheel abuts against the first outer edge.

[0018] By adopting the above technical solution, the guide wheel can be supported on the conductive wheel, and it is ensured that the guide wheel and the conductive wheel rotate synchronously, thereby avoiding the belt material from twisting due to different rotation speeds on both sides of the belt material.

[0019] The present invention is further configured such that: the guide wheel is an inclined wheel having an inclined side surface abutting against the strip material.

[0020] By adopting the above technical solution, the side of the strip material away from the pressing block abuts against the inclined side surface. When material jumping occurs, the strip material moves toward the side of the pressing block, and the strip material on the inclined side moves toward the side of the conductive wheel under the action of the pressing block, thereby ensuring that the strip material can still abut against the conductive wheel after material jumping occurs.

[0021] The present invention is further configured as follows: a second outer edge extends from the bottom surface of the guide wheel, the second outer edge abuts against the first outer edge, and the length of the first outer edge is greater than the length of the second outer edge.

[0022] By adopting the above technical solution, the stability of the rotation of the guide wheel on the conductive wheel is improved, and the jumping of the strip material caused by the asynchronous rotation of the guide wheel and the conductive wheel is avoided.

[0023] In summary, the present invention has the following effects:

[0024] 1. The strip material is connected to the electrode through the conductive wheel and continuously fed. The guide wheel ensures that the strip material can keep in contact with the conductive wheel during operation, avoiding the deviation of the strip material in the tangent direction of the conductive wheel during operation;

[0025] 2. The anti-jumping component can make the strip material have a tendency to move toward the side of the guide wheel, so that the strip material can be located in the gap between the guide wheel and the conductive wheel, avoiding the strip material from jumping along the axis of the conductive wheel. The guide wheel and the anti-jumping component ensure that the strip material is in full contact with the conductive guide wheel, avoiding the strip material from deviating from the working position and poor contact, thereby ensuring that the surface of the strip material can be evenly deposited;

[0026] 3. When material jumping occurs, the strip material moves toward one side of the pressing block, and the strip material on the inclined side moves toward one side of the conductive wheel under the action of the pressing block, ensuring that the strip material can still abut against the conductive wheel after material jumping occurs.
