Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a fixed hanger for immersion plating. Background Art

[0002] The PCB dip-plating process is a technology that applies electrochemical methods to the production of PCBs and covers a layer of metal on the PCB to ensure its conductivity and corrosion resistance. Before entering the PCB dip-plating tank, the PCB needs to be hung and fixed using a hanger. When using the existing PCB dip-plating fixed hanger, the PCB to be dip-plated is usually placed in the placement tank first, and then the staff turns the screw to drive the clamping plate to clamp and fix the PCB on the side wall of the inner cavity of the placement tank. After the PCB dip-plating operation is completed, the screw is turned in the opposite direction to release the clamping of the clamping plate on the PCB, and then the PCB is removed. However, when performing the PCB dip-plating operation, it is usually necessary to perform PCB dip-plating operations on multiple groups of PCBs at the same time. The staff needs to continuously turn multiple groups of screws to rotate, which is time-consuming and labor-intensive, and reduces the PCB dip-plating efficiency to a certain extent.

[0005] Based on the above technical features: when in use, the circuit board is placed in the installation groove, and then the staff pushes the fixing component to slide in the direction of the circuit board. The set fixing component drives the telescopic component and the clamping plate to move in the direction of the circuit board. After the clamping plate contacts the circuit board, the staff continues to push the fixing component to slide. When the constraint groove is moved to the same vertical plane as the constraint component, the set constraint component is plugged into the constraint groove under the action of its own elastic force, and the fixing component is limited by the constraint component to avoid the rebound of the fixing component. The circuit board is pushed against the side wall of the inner cavity of the installation groove by the clamping plate, so as to achieve the clamping and fixing of the circuit board by the clamping plate; in the process of clamping and fixing the circuit board by the clamping plate, if the clamping force of the clamping plate is too large, the set telescopic component will shrink adaptively, and the set telescopic component avoids the damage of the circuit board due to the excessive clamping force of the clamping plate to a certain extent.

[0006] Preferably, the fixing assembly includes a fixing rod slidably arranged on the side wall of the mounting plate, one side of the fixing rod is fixedly connected to the fixing plate, a spring 1 is wound around the rod body of the fixing rod, and the spring 1 is connected between the fixing plate and the mounting plate.

[0011] Based on the above technical features: in the process of clamping and fixing the circuit board by the clamping plate, if the clamping force of the clamping plate is too large, the set spring 2 will adaptively shrink. The set spring 2 can avoid the damage of the circuit board caused by the excessive clamping force of the clamping plate to a certain extent.

The fixed component drives the telescopic component and the clamping plate to move in the direction of the circuit board. After the clamping plate contacts the circuit board, the staff continues to push the fixing component to slide. When the constraint groove is displaced to the same vertical plane as the constraint component, the constraint component is inserted into the constraint groove under the action of its own elastic force. The fixing component is limited and constrained by the constraint component to avoid the rebound of the fixing component. The circuit board is pushed against the side wall of the inner cavity of the installation groove by the clamping plate, so as to realize the clamping and fixing of the circuit board by the clamping plate.
