Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, and more specifically to a welding positioning fixture. Background Art

[0002] During the production process of circuit boards, they need to be welded, and tooling fixtures are needed to fix them during welding.

[0003] After searching, the utility model patent with announcement number CN219938645U discloses a circuit board assembly welding positioning tool, including a workbench and fixed frames installed on both sides of the workbench, characterized in that electric push rods are installed on the two fixed frames, the output end of the electric push rods is connected to a sliding frame, a fixed plate is installed above the sliding frame, a driving motor is installed above the fixed plate, the output end of the driving motor is connected to a roller, a rubber conveying track is sleeved on the roller, and a limit plate is installed at one end of the fixed plate; the patent places the circuit board body on the workbench, uses the electric push rods to drive the sliding frame to move from both sides to clamp the circuit board body, and then the driving motor on the fixed plate drives the roller to rotate, so that the rubber conveying track can drive the circuit board body to move, and cooperates with the limit plate to move the circuit board body to the accurate position under the drive of the driving motor, thereby ensuring the accuracy of positioning and facilitating use.

[0004] However, the above patent still has the following shortcomings: although the conveyor track can drive the circuit board to move and cooperate with the limit plate to limit the circuit board, there is no support for the lower part of the circuit board, and it cannot ensure that the circuit board is in a horizontal state after clamping; and it is not convenient to fine-tune the welding angle of the circuit board during welding, which affects the difficulty of welding. For this reason, we propose a welding positioning fixture. Utility Model Content
