[0017] The present invention provides a PCB board plane semi-automatic welding robot. It has the following beneficial effects:

[0018] 1. The PCB board plane semi-automatic welding robot positions the PCB board and the wiring harness by setting a positioning mechanism. During manual welding, the wiring harness moves during the soldering process of the soldering iron or the wire sequence is placed incorrectly, which can easily cause welding misalignment. Therefore, a positioning mechanism is set to limit the position of the card box in the card assembly, and then to limit the position of the PCB board in the card box, and drive the card box to move. At the same time, when installing the wire harness, the position of the wire harness is fixed using the rotatable card frames on both sides, which is convenient for the user to check whether the position of the wire harness is correct, and then use the soldering iron to perform unified welding work on the wire harness and the PCB board to solve the above problems.

[0019] 2. The PCB board plane semi-automatic welding robot controls the position of the cylinder by setting a positioning component. After the welding work is completed, the user needs to manually disassemble the welded PCB board. The local temperature of the PCB board is high, which may cause injury to the user. Therefore, a positioning component is set. After the welding work is completed, the positioning component is on the extension frame, and the cooling mechanism is used to supply air to the cylinder and the PCB board to promote the cooling of the PCB board. At this time, the user can carry out the welding work of the next PCB board, and the height of the cylinder is easy to control, which is convenient for the installation and removal of the PCB board.

[0020] 3. The PCB board flat semi-automatic welding robot is provided with a cooling mechanism to supply air to the top positioning mechanism. Before using the equipment, by turning on the power system in the slide board, air can be supplied to the positioning mechanism through the slot, promoting the positioning mechanism to return to the initial temperature. During the use of the equipment, by turning on the power system in the slide board, the mobile box can be moved to the bottom of the extension frame to supply air to the PCB board after welding, promoting the cooling of the PCB board. After using the equipment, by adjusting the position of the fixed ball and the mobile box, air can be supplied to the slot, and the slot can be cleaned by contact or striking to promote impurities to leave the slot.

[0021] 4. The PCB flat semi-automatic welding robot adjusts and fixes the position of the PCB board and the wiring harness by setting a positioning mechanism and a cooling mechanism, which is convenient for users to place the wiring harness and check whether the wiring harness position is correct, reducing errors caused by incorrect wiring harness position, and placing and supplying air to the PCB board after welding, promoting the cooling of the PCB board, and facilitating users to safely install or remove the PCB board.

[0062] After the work is finished, the positioning column 4 and the positioning mechanism 5 are manually disassembled to expose the positioning opening 3 on the workbench 1, and the power system is turned on again to make the slide plate 708 reciprocate in the slideway 707, and then the moving box 704 is used to supply air to the positioning opening 3. The third telescopic rod 710 is turned on, and the third telescopic rod 710 drives the top plate 711 and the fixed ball 712 to move upward, and the handle 713 is manually pulled to adjust the position of the sliding frame 709 outside the curved rod 706. The sliding frame 709 drives the third telescopic rod 710, the top plate 711 and the fixed ball 712 to move, contact the positioning opening 3, and promote the impurities in the positioning opening 3 to leave the positioning opening 3.

[0063] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
