Elastic sheet type conductive track structure and PCB plating device

Abstract

The invention discloses an elastic sheet type conductive track structure and a PCB plating device. The elastic sheet type conductive track structure comprises a fixed conductive track, a movable conductive strip, a plurality of conductive blocks and a plurality of conductive elastic sheets, wherein the plurality of conductive blocks and the plurality of conductive elastic sheets are arranged between the fixed conductive track and the movable conductive strip along the length direction of the fixed conductive track; the conductive blocks are electrically connected with the corresponding conductive elastic sheets; and when the movable conductive strip moves transversely relative to the fixed conductive track, the conductive blocks and the corresponding conductive elastic sheets are electrically connected with the fixed conductive track to conduct current under the elastic action of the corresponding conductive elastic sheets. According to the scheme, the contact area during transmissionis ensured, and the condition of poor contact caused by insufficient processing precision is reduced; meanwhile, the conductive elastic sheets are connected with small conductive blocks, and the conductive elastic sheets compress the small conductive blocks during working, so that full contact and conduction are ensured, and the purpose of conducting a component in the moving process is achieved;and in addition, the influence on the conductivity is not generated by the abrasion of the track.

[0002] Today's PCB equipment needs to conduct current during movement. The method is mainly to use conductive blocks or conductive plates to frictionally conduct on the conductive track to realize power supply during movement. At present, the contact is usually sheet-to-sheet contact, and The conductive sheet material is relatively long and has a large amount of deformation. Either the two ends are tilted, or the side is not in contact with the surface, and line contact is often formed, resulting in poor conductivity. In addition, due to long-term friction, the conductive block is worn out. , the change of the contact area leads to the change of the over-power, which makes the transmission over-power difficult to control, and it is easy to cause other problems such as thicker or thinner boards in PCB equipment

[0003] In addition, when the guide rail structure of the current PCB equipment conducts current, it is easily affected by the machining accuracy and has high requirements for installation. When the conductive block is in contact with electricity, it is easy to change from surface contact to line contact or point contact. The current decreases, causing a series of problems
