Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production, in particular to a welding device for an air conditioner main control board. Background Art

[0002] The air conditioner main control board is the core component of the air conditioning system, which has command, control and protection functions, including automatic control, timed on / off, constant temperature operation, multiple mode selection, wind speed adjustment, fault self-diagnosis, etc. In the production process of the air conditioner main control board, the memory, various sensors and actuators on the board are usually soldered and fixed by welding. Therefore, welding equipment is required to weld each actuator node, as shown in the existing patent technology: After searching, the China Patent Network discloses an air conditioner circuit board welding machine with convenient position adjustment (public announcement number CN218983488U). When this type of device is working, the main control board is transported to the bottom of the welding head by a conveyor belt, and then the installation plate is pushed to move by an electric telescopic rod. The installation plate pulls the connecting plate to move through the connecting rope, and the connecting plate drives the clamping plate to move, so that the clamping plate adjusts the air conditioner circuit board to a suitable position to avoid the position of the air conditioner circuit board being offset when welding the air conditioner circuit board. At the same time, the welding head is moved down to weld the main control board.

[0003] However, there are still some shortcomings in the above-mentioned public patents and the main control board welding devices adopted in the existing market: the existing method uses an electric telescopic rod to push and pull, on the one hand, uses a pull rope to drive the clamp plate to move symmetrically to clamp and fix the electric control board, and on the other hand, pushes the welding head down for welding. Although it can fix and weld the main control board as a whole, it can only weld a limited number of main control boards. When the main control board is too large or too small, it is very easy for the clamp plate to clamp and the welding head to move down and cannot match the main control board for welding, and the flexible welding performance is relatively low. To this end, those skilled in the art provide a welding device for the main control board of an air conditioner to solve the problems raised in the above background technology. Utility Model Content

When the welding table 9 slides horizontally, the transmission gear 24 is meshed and driven along the transmission rack 22, and the meshing transmission of the transmission gear 24 and the transmission rack 22 is used to drive the clamping screw rod 23 to rotate. When the clamping screw rod 23 rotates, the positive and negative threads thereof are used to push the two sets of clamping slides 25 symmetrically along the welding table 9.
