The adjacent sides of the two heating heads 4 are fixedly connected with a heating element 5. The inner wall of the bottom of the machine body 1 is fixedly connected with one of the fixing frames 6. The bottom of the fixing plate 3 is fixedly connected with another fixing frame 6. A plurality of fixing columns 7 are fixedly connected to the outside of the fixing frames 6. A first spring 8 is sleeved on the outside of the fixing columns 7. The far sides of the plurality of first springs 8 are respectively fixedly connected with a plurality of sliding plates 9. The far sides of the plurality of sliding plates 9 are respectively fixedly connected with a plurality of second springs 10. The sliding plates 9 drive the second springs 10 to be compressed. The far sides of the plurality of second springs 10 are respectively fixedly connected with a plurality of hollow columns 11. The hollow columns 11 drive the first springs 8 to be compressed. The outer sides of the two hollow columns 11 are fixedly connected with a buffer plate 12. The buffer plate 12 drives the movement of the hollow columns 11, realizing the buffering of the welding head. By reducing or absorbing the impact from collisions, the anti-collision protection device can reduce the wear and damage of the welding equipment, thereby prolonging the service life of the equipment and reducing the maintenance cost.

[0026] Referring to Figure 1 , Figure 4 , the top of the fixing plate 3 is fixedly connected with a heat dissipation component. The heat dissipation component includes a water pump 13. The output end of the water pump 13 is fixedly connected with a pipeline 18. The input end of the water pump 13 is fixedly connected with a first connecting pipe 14. The front side of the first connecting pipe 14 is fixedly connected with a box body 15. The cooling water in the box body 15 enters the water pump 13 through the first connecting pipe 14. The bottom of the box body 15 is fixedly connected with a second connecting pipe 16. The bottom of the second connecting pipe 16 is fixedly connected with a cooler 17. After circulation, the heat dissipation of the welding head is realized, thereby reducing the temperature of the welding area. This helps to prevent excessive local temperature during welding, reduce the influence of thermal stress on the metal, and avoid deformation or other quality problems of the welding area due to overheating.

[0027] Referring to Figures 2 to 4, the bottom of the water pump 13 is fixedly connected to the rear side of the top of the fixed plate 3, improving the stability of the water pump 13. The bottom of the box body 15 is fixedly connected to the front side of the top of the fixed plate 3, improving the stability of the box body 15. The top of the cooler 17 is fixedly connected to the bottom of the fixed plate 3, improving the stability of the cooler 17. The outside of the cooler 17 is fixedly connected to the inner wall of another fixed plate 3.

[0028] Working principle: When the welding head of the diffusion welder is impacted by an external force, it will cause the buffer plate 12 to move, realizing that the buffer plate 12 drives the movement of the hollow column 11, achieving that the hollow column 11 drives the first spring 8 to be compressed, and driving the second spring 10 to be compressed through the sliding plate 9, realizing the buffering of the welding head. By reducing or absorbing the impact from the collision, the anti-collision protection device can reduce the wear and damage of the welding equipment, thereby extending the service life of the equipment and reducing the maintenance cost. When heat dissipation is required, start the water pump 13, so that the cooling water in the box body 15 enters the water pump 13 through the first connecting pipe 14. Subsequently, the cooling water enters the pipe 18 and the cooler 17 in sequence, and finally enters the box body 15 through the second connecting pipe 16. After such a cycle, the heat dissipation of the welding head is realized, and then the temperature of the welding area is reduced, which helps to prevent the local temperature from being too high during the welding process, reduce the influence of thermal stress on the metal, and avoid deformation or other quality problems in the welding area due to overheating.
