[0067] Working principle of the present invention:

[0068] The present invention is compatible with the processing of multiple products, and can perform processing according to the processing size requirements of different products. It can accurately and independently control the copper nozzle structure 31 to complete the action of pressing down the nickel sheet and cooperate with the laser emission component 2 to complete the welding work, thereby achieving precise processing. This solution monitors the pressing stroke and pressing deformation of the copper nozzle structure 31 through the elastic part 32, the displacement sensing module 6 and the pressure sensing module 7.

[0069] In this embodiment, one of the dotted line parts is a control module 13, which is used to process data and make corresponding action commands, so as to facilitate monitoring the downward pressure stroke and downward pressure deformation of the copper nozzle structure 31. The downward pressure of the copper nozzle structure 31 and the deformation generated can be monitored and acquired through the pressure sensing module 7 and the CCD module 5, and the downward pressure stroke is monitored by the displacement sensing module 6 to acquire data. Specifically, the displacement sensing module 6 is a displacement sensor, and the pressure sensing module 7 is a pressure sensor. The sensor is arranged on one side of the copper nozzle structure 31, and the pressure sensor is arranged on the elastic member 32, and the elastic member 32 is a spring. When the elastic member 32 is compressed, the pressure sensor can detect the elastic force accordingly, so the downward pressure data N1 of the copper nozzle structure 31 can be accurately obtained.

[0070] As attached Figure 3As shown, the bottom of the copper nozzle structure 31 is wide at the top and narrow at the bottom, and the second opening is used to align the corresponding nickel sheet and press it onto the palladium sheet. The interior of the copper nozzle structure 31 is hollow, and the top of the copper nozzle structure 31 is provided with a first opening, and the second opening is located on the positive projection of the first opening, that is, directly below the first opening; the laser beam can be emitted through the first opening and the second opening in sequence, wherein the side wall of the copper nozzle structure 31 is also connected to a dust extraction and gas extraction pipeline to discharge the generated polluted gas. The linear guide rail 12 and the linear slider 121 can ensure the linear accuracy of the copper nozzle structure 31 when it is lifted up and down. Further improve the stroke position accuracy of the copper nozzle structure 31.

[0071] like Figure 1 As shown, the dotted parts are respectively the X-axis moving component 10, the Y-axis moving component 11 and the control module 13. In this embodiment, the Z-axis moving component 1 is arranged at the moving end of the X-axis moving component 10. The X-axis moving component 10 can drive the Z-axis moving component 1 to move along the X-axis direction, and the Y-axis moving component 11 can drive the X-axis moving component 10 and the Z-axis moving component 1 to move along the Y-axis direction.

The Z-axis moving component 1 can select a Z-axis module, that is, the fixed plate mechanism is fixed on the Z-axis slider, and the fixed plate structure 4 can move along the Z-axis direction. The Z-axis direction is Figure 1 The up and down vertical directions in the X-axis direction are horizontal and the Y-axis direction is horizontal. The laser emission component 2 includes a laser head, a galvanometer, etc., which are used to emit laser beam welding. The CCD module 5, the laser emission component 2, the copper nozzle component 3, the lighting lamp 15, and the wind knife 14 are all installed on the fixed plate structure 4 and move together. The output tube of the lighting lamp 15 can swing the output tube of the lighting lamp 15 according to the specific situation through the shaping tube. Similarly, the output end of the wind knife 14 can output gas through the air duct, and the air duct can select a shaping tube to adjust the wind direction according to the specific situation.
