[0029] Example 1

[0030] The embodiment of the present invention provides a semi-automatic assembly device for air-cooled welding guns, such as Figure 1-8 As shown, it includes a gun tip automatic locking station 5, a switch welding station 4, a thermoplastic mechanism 3, an automatic screw locking mechanism 2 and an upper and lower conveyor belt 8 which are arranged in sequence from right to left. A transfer workbench 9 is arranged on the conveyor belt 8. A gun tip 10, a circuit board, a heat shrink tube 12 and a cable 11 are arranged on the transfer workbench 9. The conveyor belt 8 passes through the gun tip automatic locking station 5, the switch welding station 4, the thermoplastic mechanism 3 and the automatic screw locking mechanism 2 from right to left. The gun tip automatic locking station 5 is used to tighten the connection between the gun tip 10 and the cable, and the thermoplastic mechanism 3 is used to heat the heat shrink tube 12.

[0031] Preferably, a handle and a control line are also provided on the transfer workbench 9 , the gun head 10 is spirally connected to the cable 11 , and a heat shrink tube 12 is sleeved at the connection between the gun head 10 and the cable 11 .

[0032] Preferably, a preparation table 6 is provided on the front side of the automatic screw locking mechanism 5 , a lifting platform 1 7 is provided on the front side of the preparation table 6 , and a lifting platform 2 1 is provided on the left side of the automatic screw locking mechanism 2 .

[0033] Among them, the lifting platform 1 7 and the lifting platform 2 1 are used to raise and lower the height of the circulation workbench 9 so that the circulation workbench 9 runs on the upper conveyor belt 8 or the lower conveyor belt 8.

[0034] The working principle and beneficial effects of the above technical solution are as follows: the first employee prepares all the materials needed for the welding gun at one time on the preparation table 6, and then correctly installs these materials (gun head 10, cable 11, heat shrink tube 12, circuit board, handle and control line) on the transfer workbench 9, screws the cable 11 into the gun head 10, and transports the transfer workbench 9 to the gun head automatic locking station 5 through the upper conveyor belt 8. The gun head automatic locking station 5 tightens the connection between the gun head 10 and the cable 11 to the set torque to ensure the standardization of the torque; then the upper conveyor belt 8 transports the transfer workbench 9 to the switch welding station 4, and the switch welding station 4 welds the control line to the circuit board After that, the upper conveyor belt 8 transports the transfer workbench 9 to the thermoplastic mechanism 3, and the thermoplastic mechanism 3 heats the heat shrink tube 12, thereby ensuring that the heat shrink tube 12 completely covers the connection between the gun head 10 and the cable 11; then the upper conveyor belt 8 transports the transfer workbench 9 to the automatic screw locking mechanism 2, at which time the second employee takes out the assembled gun head 10 and assembles it to the handle, and then puts the assembled gun head 10 back on the transfer workbench 9, and the automatic screw locking mechanism 2 automatically locks the screws where the screws need to be locked on the handle, and the locked welding gun is taken down by the second employee, and then the transfer workbench 9 enters the lower conveyor belt 8 and returns to the preparation table 6, and the process ends;

[0035] By setting up an automatic gun head locking station 5, the torque at the connection between the gun head 10 and the cable 11 can be effectively ensured, and by setting up an automatic screw locking mechanism 2, the torque of the screw can be effectively ensured, thereby improving the stability of the product. At the same time, there is no need for manual screwing in of the screws and tightening of the connection between the gun head and the cable, which can effectively save labor, reduce the labor intensity of workers, and improve production efficiency.

[0036] Example 2

[0037] On the basis of the above-mentioned embodiment 1, Figure 3-5 As shown, the thermoplastic mechanism 3 includes a heating box 13 and a cooling box 18. The transfer workbench 9 passes through the heating box 13 and the cooling box 18 in sequence. The heating box 13 is used to heat the heat shrink tube 12 so that the heat shrink tube 12 completely covers the connection between the gun head 10 and the cable 11. The cooling box 18 is used to cool the heat shrink tube 12.

[0038] The working principle and beneficial effects of the above technical solution are as follows: when the upper conveyor belt 8 conveys the transfer workbench 9 into the heating box 13, the heating box 13 heats the heat shrink tube 12 so that the heat shrink tube 12 completely covers the connection between the gun head 10 and the cable 11, and then the upper conveyor belt 8 continues to run. When the transfer workbench 9 enters the cooling box 18, the cooling box 18 cools down the heat shrink tube 12 to prevent the temperature of the heat shrink tube 12 from being too high, which would cause burns to the staff when the second employee removes the assembled gun head 10 and assembles it to the handle. The system is safer and more practical.

In the process of the heat shrink tube 12 shrinking under high temperature, harmful substances will be discharged, and the gas in the heating box 13 will enter the adsorption box 17 through the fan 14 and the exhaust pipe 16 (at this time, the circulating workbench 9 is transported to the cooling box 18). ), after the several filters 25 in the exhaust pipe 16 filter the harmful exhaust gas, the adsorption liquid in the adsorption box 17 adsorbs the harmful substances, and then after adsorption and cooling (the hot air will be cooled after passing through the liquid, and the liquid is at room temperature), the gas is sprayed to the position of the heat shrinkable tube 12 through the connecting pipe 20 and the jet plate 19, thereby cooling the heat shrinkable tube; by setting up several filters 25 and adsorption liquid, the exhaust gas generated by heating can be effectively cleaned.
