Description

Technical Field

[0001] The utility model relates to the technical field of circuit board welding positioning, in particular to a circuit board welding positioning tool. Background Art

[0002] Circuit boards are essential components in electronic devices. They enable conductive connectivity between various components in electronic devices. Circuit boards generally include substrates with various pin components welded on the top of the substrate. The pin components are used for conductive connectivity with various circuits and are the most important components on circuit boards. A circuit board usually has multiple pin components with different heights. During the processing of circuit boards, various components need to be welded on the circuit boards. Therefore, welding is the most important and indispensable processing technology on circuit boards. When welding circuit boards, positioning tooling is needed to position and fix the circuit boards to ensure that the position of the circuit boards does not move.

[0003] A circuit board welding positioning tool disclosed in the Chinese utility model patent application disclosure CN219718657U, the circuit board welding positioning tool, although by setting a strong suction cup, a threaded rod, a clamping plate auxiliary block, a support frame and a rotating rod, the bottom surfaces of the two strong suction cups are respectively adsorbed to the installation surface, the positioning seat is stable enough, the circuit board is placed in the middle position of the two clamping plates, and the two rotating rods are rotated clockwise in turn, and then the threaded rod connected thereto is driven to rotate. Since the outer wall of the auxiliary block is in contact with the inner wall of the auxiliary groove, when the threaded rod rotates, the auxiliary block threadedly sleeved at one end thereof moves to one side, and the distance between the two clamping plates is reduced. The distance will gradually decrease, so that both sides of circuit boards of different lengths can be clamped, which solves the problem that the positioning seat is not stable enough when clamping the circuit board. However, double-sided welding operations are required when welding some circuit boards. After the welding work on one side of the circuit board is completed, the circuit board welding positioning tool needs to contact the positioning of the circuit board and flip the circuit board, and then re-position the circuit board before the welding operation can be performed on the other side of the circuit board. The process of flipping the circuit board and re-positioning the circuit board takes a certain amount of time, thereby reducing the efficiency of welding the circuit board. Therefore, a circuit board welding positioning tool is needed to solve the above problems. Utility Model Content
