Description

Technical Field

[0001] The present application relates to the technical field of welding positioning fixtures, and in particular to a welding positioning fixture for a conductive connector. Background Art

[0002] In the field of electronic manufacturing and electrical engineering, the quality of welding of conductive connectors is directly related to the performance and reliability of the entire circuit or system. It involves connecting conductive materials (such as metals) by welding to ensure that current can effectively flow from one component to another. Specific welding equipment is usually required. During the welding process, the two conductive materials to be welded often need to be fixed with a positioning fixture, which can accurately fix the position of the connector and the connected components. For example, in the circuit board welding of electronic equipment, the two conductive conductors are fixed separately, and the positioning fixture can accurately place the chip in the correct position to ensure that the conductors can be fixed accordingly when welding. This is like arranging an exclusive "seat" for each welding component so that it will not be offset during the welding process. This precise positioning is particularly important for mass production, which can ensure that the welding position error of each product is within a very small range and improve the consistency of product quality.

[0003] Through searching, Chinese patent application number CN202223334897.0 discloses a welding tool positioning fixture, including a workbench, a first slide groove is provided at the upper end of the workbench, a first slider is slidably connected inside the first slide groove, the upper end of the first slider is fixedly connected to a base plate, the front and rear sides of the upper end of the base plate are fixedly connected to vertical plates, the upper left side of the vertical plate is slidably connected to a second slider, and the upper end of the second slider is fixedly connected to a movable seat. The present invention adopts the above structure, by setting the upper clamp block and the lower clamp block in the clamping assembly, when the upper clamp block is used to clamp the workpiece, the upper clamp block is driven to move on the side wall of the side plate through the movable assembly by rotating the adjusting screw, and the upper clamp block and the lower clamp block can clamp the upper and lower positions of the workpiece. If it is necessary to clamp the left and right positions of the workpiece, the upper clamp block and the lower clamp block are merged together by rotating the adjusting screw.

[0004] With respect to the above-mentioned related technologies, the inventors have found the following defects: during the welding process, when welding is performed, when in aerospace, military or medical equipment, double-sided welding may be required to ensure the highest reliability and safety. When double-sided welding is performed on the material, the material needs to be disassembled and turned over and reinstalled, resulting in a cumbersome process, which affects the processing efficiency during double-sided welding. At the same time, the exhaust gas is directly discharged into the air, resulting in direct waste of the flowing air volume, causing energy waste. Summary of the invention

[0028] See also Figure 1 The linkage assembly 12 includes a hose 121 fixedly connected to the output end of the vacuum pump 11, a fixing frame 122 fixedly connected to one side of the mounting plate 4, and an air suction hood 123 fixedly connected to one side of the fixing frame 122 and matched with the hose 121.
