Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production equipment, in particular to a circuit board processing auxiliary device. Background Art

[0002] Circuit boards can be divided into three major categories according to the number of layers: single-sided boards, double-sided boards, and multi-layer circuit boards. On the most basic single-sided PCB, parts are concentrated on one side and wires are concentrated on the other side. Double-sided boards are an extension of single-sided boards. When single-layer wiring cannot meet the needs of electronic products, double-sided boards must be used. Multi-layer boards refer to printed boards with more than three layers of conductive graphic layers and insulating materials laminated between them, and the conductive graphics are interconnected as required. The circuit boards must be fixed by positioning auxiliary devices during processing so that the circuit boards can be processed.

[0003] However, the existing circuit boards have certain drawbacks. First, the positioning ratio of the circuit boards is relatively poor. When replacing circuit boards with different proportions, repositioning is required. In addition, it is troublesome to clamp the circuit boards, as they cannot be clamped according to the proportions. Therefore, a circuit board processing auxiliary device is proposed.

[0004] A circuit board processing positioning auxiliary device disclosed in the announcement number CN214507508U, although, the circuit board processing positioning auxiliary device includes a fixed base plate and a placement plate, the placement plate is provided with a placement cavity inside, the placement plate is provided with fixing grooves on both sides, the fixed base plate is provided with a clamping device inside the placement cavity and the fixing groove, the clamping device includes a connecting rod, a telescopic spring, a V-shaped block, a stepped groove, a fixing hole and a limiting rod, the fixed base plate is provided with a fixing hole on the side wall of the fixing groove, and a connecting rod is provided inside the fixing hole. The circuit board processing positioning auxiliary device described in the utility model belongs to the field of circuit board processing, and can clamp the V-shaped block between two V-shaped blocks by a telescopic spring to achieve the effect of auxiliary fixing, and the positioning column can be moved along the diagonal of the placement cavity by a driving motor, so that circuit boards of equal proportions can be clamped, and the positioning can be more accurate and convenient to adjust.

[0005] Although the above patent achieves the goal of moving the positioning column along the diagonal of the placement cavity by driving the motor, so that circuit boards of equal proportions can be clamped, and the positioning can be more accurate and convenient to adjust; however, the device only fixes the circuit board from two sides, and the fixation is still not firm. It is not easy to fix the circuit board in multiple directions to improve the stability of the circuit board during processing.

[0006] Therefore, it is necessary to invent a circuit board processing auxiliary device to solve the above problems. Utility Model Content
