[0031] Please refer to Figure 1 - Figure 5 , this embodiment provides a new energy module laser welding machine, including:

[0032] Support frame 1;

[0033] Preferably, the supporting frame 1 includes a mounting plate 110 and a supporting frame 120 connected to the mounting plate 110 .

[0034] The laser galvanometer welding assembly 2 is installed on one end face of the mounting plate 110 of the support frame 1, and the other end face of the mounting plate 110 is used to connect the power output end of the XYZ three-axis gantry module (not shown). The XYZ three-axis gantry module is used to drive the support frame 1 and the components connected to the support frame 1 to move and adjust the position, so as to facilitate the alignment welding of the new energy module.

[0035] A welding clamping assembly 3, wherein the welding clamping assembly 3 comprises a floating plate 310 and a plurality of welding pressure heads 320 connected to the floating plate 310;

[0036] The welding clamping assembly 3 is arranged below the laser galvanometer welding assembly 2, and a plurality of welding pressure heads 320 are used to press the corresponding positions of the connecting pieces at a plurality of welding points and the main body of the new energy module, and expose openings for the laser light to pass through.

[0037] A buffer 4, wherein the buffer 4 connects the supporting frame 1 and the floating plate 310;

[0038] A guide assembly 5, the guide assembly 5 is connected to the support frame 1 and the floating plate 310, and is used to guide the moving direction of the welding clamping assembly 3;

[0039] The limit assembly includes a stop block 610 connected to the support frame 1 and a limit block 620 connected to the welding clamping assembly 3. When the welding clamping assembly 3 moves away from the laser galvanometer welding assembly 2 to an extreme position, the limit block 620 abuts against the stop block 610.

[0040] Driven by the XYZ three-axis gantry module, the support frame 1 is driven to move to above the predetermined position of the new energy module to be welded, and the Z-axis moving module of the XYZ three-axis gantry module drives the support frame 1 to approach the new energy module, and the multiple welding pressure heads 320 at the bottom respectively and synchronously press the connecting pieces of the corresponding welding points. Since the guide component 5 is provided, after the welding clamping component 3 contacts and presses the new energy module, the support frame 1 continues to move downward. Under the guidance of the guide component 5, the support frame 1 moves without deflection, and the laser galvanometer welding component 2 on the support frame 1 also obtains precise limit alignment, so that when the new energy module is laser welded later, it can also be precisely welded.

[0041] Due to the provision of the buffer 4, in the process of the XYZ three-axis gantry module driving the support frame 1 to move, when the pressure of the connecting pieces of the corresponding welding points by the multiple welding pressure heads 320 reaches the specified pressure, and the laser focal length of the laser welder generated by the height distance of the laser galvanometer welding assembly 2 reaches the specified focal length, the buffer 4 can play a buffering role. Combined with the spring provided on the welding pressure head 320 itself, it can avoid damage caused by the rigid support of the welding pressure head 320 on the new energy module, make up for the limited effect of the spring provided in the welding pressure head 320, and make the laser focal length adjustment of the laser galvanometer welding assembly 2 more flexible and efficient, thereby improving the overall processing efficiency and processing quality.

[0042] The height distance between the support frame 1 and the new energy module is determined. When the limit block 620 abuts against the stop block 610, it can limit and prevent the welding clamping assembly 3 from further increasing the abutting pressure on the processed new energy module, thereby protecting the new energy module from being crushed and damaged.

[0043] Please refer to Figure 5 , including a pressure sensor 7, wherein the pressure sensor 7 is arranged at the connection between the buffer 4 and the floating plate 310.

[0044] The pressure sensor 7 is used to collect the holding pressure of the welding pressure head 320 on the floating plate 310 on the new energy module, and transmit it to the host computer, and the host computer controls the driving movement of the XYZ three-axis gantry module and / or the buffer 4.

[0045] Please refer to Figure 4 and Figure 5 , including a cleaning component, the cleaning component includes a dust extraction hood 810 connected to the end surface of the floating plate 310 and enclosing multiple upper ports of the welding pressure head 320, and a conveying pipeline 820 connected to the dust extraction hood 810; the supporting frame 1 is provided with a avoidance through hole 121 for the movable avoidance of the conveying pipeline 820.

[0046] The dust extraction hood 810 is used to enclose the area where welding smoke is generated during the laser welding process when the laser galvanometer welding assembly 2 is working. The welding smoke in the dust extraction hood 810 is extracted and transported to the processing equipment through the conveying pipeline 820 for processing, thereby preventing environmental pollution. In the debugging and alignment stage, the welding clamping assembly 3 can move relative to the support frame 1, and the dust extraction hood 810 is connected to the end face of the floating plate 310. Therefore, the avoidance through hole 121 is provided on the support frame 1 to prevent interference with the movement of the conveying pipeline 820.

[0047] Please refer to Figure 3 , including a laser ranging component 9 connected to the supporting frame 1.

[0048] Preferably, the laser ranging component 9 is installed on the other end face of the mounting plate 110, and is used to collect the height distance information of the support frame 1 driven by the XYZ three-axis gantry module from the processed new energy module, and transmit it to the host computer to control the operation of the XYZ three-axis gantry module.

[0049] Please refer to Figure 2 and Figure 3 , including a CCD camera 10 connected to the supporting frame 1.

[0050] The CCD camera 10 is used to collect the horizontal relative position information of the supporting frame 1 relative to the processed new energy module, transmit it to the host computer, and control the operation of the XYZ three-axis gantry module.

[0051] Preferably, the CCD camera 10 is mounted on the other end surface of the mounting plate 110 , that is, the back side of the laser galvanometer welding assembly 2 .

[0052] Please refer to Figure 2 and Figure 3, including an observation platform 11; the observation platform 11 is arranged adjacent to the CCD camera 10; the observation platform 11 includes a driving device 1110 connected to the welding clamping assembly 3, and the driving device 1110 is used to drive the observation platform 11 to move so that its observation area moves to or leaves the visual recognition area of ​​the CCD camera 10.

[0053] In addition to cooperating with the XYZ three-axis gantry module to adjust the position of the support frame 1, the CCD camera 10 can also act as a magnifying glass or microscope. For example, the test welded parts during the trial operation of the laser galvanometer welding assembly 2 are placed in the observation area of ​​the object observation platform 11, and the drive device 1110 drives the object observation platform 11 to move to the visual recognition area of ​​the CCD camera 10 to magnify and display it for easy observation. When the new energy module laser welding machine is operating normally, the drive device 1110 drives the object observation platform 11 to move so that it leaves the visual recognition area of ​​the CCD camera 10 to avoid interference. This design structure is ingenious and serves two purposes.

[0054] Please refer to Figure 1 and Figure 4 The guide assembly 5 includes a slide rail 510 connected to the support frame 1 and a slide seat 520 connected to the floating plate 310; the slide seat 520 is slidably connected to the slide rail 510; and the limit block 620 is installed on the side wall of the slide seat 520.

[0055] Please refer to Figure 3 The laser distance measuring assembly 9 is connected to the supporting frame 1 through an XYZ adjustment frame 12.

[0056] The XYZ adjustment frame 12 includes a plurality of connecting rods, a clamping plate, and a screw and nut group; the clamping plate is provided with a clamping hole for the connecting rod to pass through, and the connecting rod and the clamping plate are tightened or loosened by the cooperation of the screw and nut. After loosening, the connecting rod can move relative to the clamping plate, and the plurality of connecting rods and clamping holes correspond to the orientation of the XYZ space rectangular coordinate system, so that the laser ranging component 9 can be installed to obtain a rich and free range of adjustment, which can adapt to the processing of new energy modules of different height specifications and improve the versatility of the equipment.

[0057] Preferably, the buffer 4 is a cylinder with a cylinder buffer valve.

[0058] In some embodiments, the XYZ three-axis gantry module first drives the support frame 1 to move to the height corresponding to the laser focal length of the laser galvanometer welding assembly 2, and then the cylinder with a cylinder buffer valve having an active driving force and a buffering function, and the buffer 4 drives the welding clamping assembly 3 to approach the new energy module, so that multiple welding pressure heads 320 are used to press and hold the corresponding positions of the connecting pieces of multiple welding points and the main body of the new energy module with appropriate pressure in combination with the pressure sensor 7.

[0059] Please refer to Figure 1 and Figure 5 , including a wind knife assembly 13 connected to the supporting frame 1.

[0060] Preferably, the air knife assembly 13 is mounted on the mounting plate 110 and is located on the same end surface as the laser galvanometer welding assembly 2 .

[0061] The dust extraction hood 810 has an opening to facilitate the penetration of the laser used in the laser galvanometer welding assembly 2. This opening will also cause welding smoke to escape to the outside. By setting up the wind knife assembly 13, the welding smoke can be suppressed to prevent it from being exposed.
