The filter box 61 is connected to the return air port 42 through a pipeline, and the purge gas source 62 is connected to the air inlet 41 through a pipeline. The filter box 61 is used to filter slag and dust in the gas, and the purge gas source 62 is used to supply purge gas. In this embodiment, the purge gas is air. In other embodiments, the purge gas can also be nitrogen or helium. The purpose of using air in this application is to reduce costs.

[0063] The filter box 61 may be a combination of a filter membrane and a spray head, and the filter membrane and the spray head are used to filter impurities such as slag and dust in the air, and the filtered air can continue to be supplied and used. In other embodiments, the filter box 61 may also be other structures that can filter impurities such as slag and dust in the air.

[0064] Reference Figure 2 and Figure 3Optionally, both the air inlet 41 and the air return port 42 can be set to a flared shape to expand the gas purging range and the gas recovery range. In actual use, when the cover body 40 is above the base 20, the purge system 60 can be opened, and the copper-clad steel material 10 is placed under the cover body 40.

[0065] Reference Figure 2 , wherein the rotating sleeve 33 can drive the inner rod 32 to rotate when rotating, so that the rotation and lifting of the hot melt head 31 are independent of each other. In one embodiment, the inner wall of the rotating sleeve 33 is provided with a limit groove 34 extending along the axis of the rotating sleeve 33, and the outer wall of the inner rod 32 is provided with a limit strip 35 extending along the axis of the inner rod 32. The limit strip 35 is slidably penetrated in the limit groove 34, so that the inner rod 32 can slide relative to the rotating sleeve 33, and the rotating sleeve 33 can drive the inner rod 32 to rotate when rotating.

[0066] The hot melt head control device 70 includes a hot melt head angle control component 71 and a hot melt head lifting control component 72. The hot melt head angle control component 71 is used to drive the rotating sleeve 33 to rotate, and the hot melt head lifting control component 72 is used to drive the inner rod 32 to rise and fall.

In other embodiments, the hot melt head angle control component 71 can also be other structures that can drive the rotating sleeve 33 to rotate.

[0067] The hot melt head 31 is rotated by controlling the hot melt head angle control component 71 so that different surfaces of the hot melt head 31 can contact the copper-clad steel material 10. On the one hand, it can prevent the hot melt head 31 from being hot-melted at a certain point for a long time, thereby extending the service life of the hot melt head 31. On the other hand, different hot melting points can be directed toward the air inlet 41, and the airflow ejected from the air inlet 41 can be used to blow away the slag on the surface of the hot melt head 31, thereby improving the cleaning effect and enhancing the subsequent hot melting quality of the hot melt head 31.

[0068] In this embodiment, the hot melt head lifting control assembly 72 includes a telescopic member 721 and a connecting plate 722. The telescopic member 721 is installed on the top plate 23, and the connecting plate 722 is fixed to the telescopic end of the telescopic member 721. The top of the inner rod 32 is rotatably connected to the connecting plate 722. The telescopic member 721 drives the connecting plate 722 to rise and fall, and then drives the inner rod 32 to rise and fall, so that the hot melt head 31 can enter and exit the hot melt groove 212 to achieve hot melting. Optionally, the telescopic member 721 is a cylinder, a hydraulic cylinder or an electric push rod.

[0069] refer to Figure 4 and Figure 5 In one embodiment, the side wall of the cover body 40 is provided with an escape groove 43 for the copper-clad steel material 10 to pass through, and the escape groove 43 is through-through downward, so that when the cover body 40 moves downward, the copper-clad steel material 10 can pass into the escape groove 43. Among them, the base 20 is slidably connected with a sealing block 80. When the hot-melt space is formed, the sealing block 80 can block the escape groove 43 to form a relatively sealed hot-melt space. The relatively sealed hot-melt space is used to reduce the leakage of inert gas and temperature, and improve the hot-melt quality and efficiency.

[0070] Among them, the top of the sealing block 80 is adapted to the shape of the copper-clad steel material 10, so that the top of the sealing block 80 fits against the outer wall of the copper-clad steel material 10 to seal the avoidance groove 43. Similarly, the top side of the avoidance groove 43 is also adapted to the surface of the copper-clad steel material 10.

[0071] Reference Figure 5 , the bottom end of the sealing block 80 is provided with a first wedge surface 801, and a sealing block control component 81 for driving the sealing block 80 to move is provided in the base 20. In this embodiment, the sealing block control component 81 includes a wedge block 811 and a wedge block control member 812, the wedge block 811 is slidably connected in the base 20, the wedge block 811 is provided with a second wedge surface 813, the second wedge surface 813 is slidably abutted with the first wedge surface 801, and the wedge block control member 812 is used to drive the wedge block 811 to move to control the position of the sealing block 80. Optionally, the wedge block control member 812 can be a cylinder, an electric push rod, etc., and the wedge block control member 812 can be used to push the sealing block 80 into the avoidance groove 43 to seal the avoidance groove 43. After the wedge block 811 retracts, the sealing block 80 can be moved down and reset under the action of gravity, or a retraction spring can be set between the wedge block 811 and the base 20, and the retraction spring can be used to reset.

[0072] Since the hot-melt space is sealed, the inert gas system 50 can be used to increase the pressure of the hot-melt space. At this time, the pressure can be increased by closing the return air port 42 or reducing the return air volume of the return air port 42. After the pressure is increased, hot melting is performed. Hot melting under high pressure can more effectively exclude oxygen and reduce the possibility of oxidation and corrosion. On the other hand, it also helps to improve the bonding strength of the material after hot melting, because high pressure can promote contact and diffusion between materials. In order to improve the sealing effect, a sealing pad or a sealing ring can be installed at the corresponding active part.

[0073] In other embodiments, if high-pressure hot melt is not needed, only the avoidance groove 43 may be opened without providing the sealing block 80. In this case, part of the inert gas will leak from the avoidance groove 43, but since the return air port 42 is provided, the amount of leakage will not be excessive and can be ignored.

[0074] Reference Figure 1 and Figure 3 In addition, the base 20 is provided with a clamping assembly 90 and a copper-clad steel control assembly 91.
