[0039] In the production process of lithium battery modules, welding is a process to ensure the vibration resistance and life of the battery after installation. However, the assembly of the battery module requires the shaping and combination of multiple parts. The coordination between the battery cell, thermal insulation pad and insulating cover will affect the assembly of the battery module and the seam effect of the end and side panels. The gap size of the seam and the height difference of the coordination will affect the final formation of the weld.

[0040] During the design process, the inventors discovered that the ultrasonic-assisted laser brazing disclosed in the prior art can solve the problems of poor wetting and spreading, insufficient filling, porosity, and incomplete penetration of the brazing material during laser brazing (melting) of dissimilar metals. However, this technology cannot match the current engineering conditions.

[0041] In view of this, if Figure 1-Figure 3As shown, in the first aspect, the present application provides a welding device, which is used to weld a workpiece 400 to be welded, wherein the workpiece 400 to be welded includes but is not limited to a lithium battery module, and the workpiece 400 to be welded is placed on a tray 500, and a fixing block 600 is arranged on the tray 500, and the fixing block 600 is configured to clamp and fix the workpiece 400 to be welded, and the welding device includes: a camera mechanism 100, a welding mechanism 200 and a vibration mechanism 300, the camera mechanism 100 monitors the weld condition, the welding mechanism 200 is used to emit a laser beam 203 to weld the workpiece 400 to be welded, wherein the laser beam 203 emitted by the welding mechanism 200 moves according to the path compiled by the internal program, and the vibration mechanism 300 is used to apply high-frequency vibration ultrasonic waves to the weld area that is about to solidify, so as to improve the sufficient flow and wetting and spreading effect of the molten solder, and avoid the occurrence of defects such as incomplete welding and undercut.

[0042] Specifically, the camera mechanism 100 is arranged on one side of the workpiece 400 to be welded, so as to monitor the weld of the workpiece 400, and the welding mechanism 200 is arranged to weld the weld according to the feedback of the camera mechanism 100; the vibration mechanism 300 is arranged with a vibration end, and the vibration end is arranged on one side of the workpiece 400 to be welded, and a preset angle is formed between the vibration end and the laser beam 203 of the welding mechanism 200, wherein the vibration end is arranged to vibrate the weld according to the feedback of the camera mechanism 100.

[0043] Exemplarily, the camera mechanism 100 uses an industrial camera with pixels that meet the specifications. The camera mechanism 100 includes but is not limited to a CCD camera (Charge coupled Device, which can be called a CCD image sensor). A CCD camera is a semiconductor device that can convert optical images into digital signals. There are many neatly arranged capacitors on the CCD camera that can sense light and convert images into digital signals. Through the control of an external circuit, each small capacitor can transfer the charge it carries to its adjacent capacitor.

[0044] The vibration end and the laser beam of the welding mechanism 200 are distributed at a preset angle, which can be 0° to 90°, or greater than 90°, etc. It can be set according to the specific situation, and it is only necessary to ensure that the vibration end and the laser beam do not interfere with each other.

[0045] It can be understood that when the workpiece 400 to be welded is a lithium battery module, the welding device is used to weld the end and side plates of the lithium battery module. At the same time, in order to improve the connection quality of the weld, the welding condition is monitored by the camera mechanism 100 before welding. If there is no gap, welding can be performed. If the gap exceeds the rule, the size is fed back to the industrial computer, and the system locates the threshold of the weld width, determines the compensation value of the vibration mechanism 300, etc., and at the same time, the side seams of the end and side plates are compensated and clamped until the weld is compliant, and welding can be performed through the welding mechanism 200; when the welding mechanism 200 completes the welding of the workpiece 400 to be welded, the camera mechanism 100 takes pictures of the weld shape and detects defects such as holes, length, width and cracks on the weld surface. If there are defects, they flow into the NG position and wait for disassembly. If there are no defects, they flow into the next process for assembly.

[0046] In the technical solution of the embodiment of the present application, the workpiece 400 to be welded is placed at a specified position and clamped by a corresponding fixture. The camera mechanism 100 moves to the welding position. The camera mechanism 100 monitors the weld condition before and after welding to achieve real-time feedback on the weld gap, improve automation, reduce the number of products with weld failures, and improve process benefits. If the welding conditions are met, a weld gap defect-free signal is issued. The vibration end of the vibration mechanism 300 is aligned with the plate on one side of the weld and is close to the workpiece 400 to be welded. The welding mechanism 200 emits a laser beam 203 for welding. The vibration end vibrates the workpiece 400 to ensure that the pores in the weld escape in time, and the welding blast holes are filled with flow to improve the welding strength, avoid stress concentration near the pores in the weld and the tendency of cracks in the workpiece 400 to be welded during use, thereby achieving the purpose of optimizing the weld quality.

[0047] like Figure 3 As shown, the vibration mechanism 300 includes a slide assembly, a fixture assembly and a vibration assembly, the slide assembly is connected to the fixture assembly, the fixture assembly is connected to the camera mechanism 100 and the vibration assembly, and the vibration assembly is configured to vibrate the weld.

[0049] In the technical solution of the embodiment of the present application, the vibration component and the camera mechanism 100 are integrated in the fixture assembly. Before welding, the welding condition is monitored by the camera mechanism 100, which is conducive to compensating and adjusting according to the width of the weld gap. At the same time, the vibration component is moved in multiple directions through the slide assembly to achieve a better vibration effect. At the same time, for the welded parts 400 with low assembly flatness, the molten pool is guided to flow after ultrasonic vibration to fill the welding holes and low seams, thereby reducing the number of products with weld failure and improving the process yield.

[0050] In some embodiments, the vibration assembly includes a vibration head 301 and a push rod 302. The vibration head 301 is connected to the push rod 302. The vibration head 301 includes but is not limited to an ultrasonic vibration head, and the push rod 302 includes but is not limited to an electro-hydraulic push rod. The push rod 302 can be adjusted for compensation according to the monitoring of the camera mechanism 100. By arranging the vibration head 301 on the push rod 302, it is beneficial to put the vibration head 301 close to the workpiece 400 to be welded, thereby achieving a better vibration effect.

[0051] In some embodiments, the clamp assembly includes a first clamp 303 and a second clamp 304, the first clamp 303 and the second clamp 304 can be located on the same plane, the first clamp 303 is connected to the camera mechanism 100, the second clamp 304 is connected to the vibration assembly, and the second clamp 304 is configured to be used for adjusting the vibration position of the vibration assembly (that is, the position where the vibration assembly performs ultrasonic vibration); exemplarily, the clamp assembly also includes a connecting rod, the connecting rod is connected to the slide assembly, the connecting rod is distributed in the horizontal direction, and one end of the connecting rod is configured with the first clamp 303, and the other end of the connecting rod is configured with the second clamp 304, the second clamp 304 includes a male end and a female end, the male end is connected to the female end (for example, a threaded connection), the male end is fixed to the connecting rod, and the female end is sleeved on the push rod 302, and the vibration position of the vibration assembly is adjusted by adjusting the position of the female end relative to the male end (for example, adjustment of 0 to 360° in the horizontal direction).

[0052] In the technical solution of the embodiment of the present application, the first clamp 303 is connected to the camera mechanism 100, and the second clamp 304 is connected to the vibration component, so that the camera mechanism 100 and the vibration component can be integrated. During the welding and vibration process of the weld, the camera mechanism 100 can be used to monitor and improve the process yield.

[0053] Please refer to Figure 3The slide assembly includes a first slide 305 and a second slide 306, the first slide 305 is connected to the second slide 306, the second slide 306 is connected to a fixture assembly, the fixture assembly can be set to move relative to the second slide 306, the second slide 306 can be set to move relative to the first slide 305, and the first slide 305 is configured to be distributed along a first direction, and the second slide 306 is configured to be distributed along a second direction, wherein the first direction is perpendicular to the second direction, the first direction is parallel to the above-mentioned horizontal direction, the first direction includes but is not limited to the X direction, and the second direction includes but is not limited to the Z direction.

[0054] In the technical solution of the embodiment of the present application, the first slide 305 is connected to the second slide 306, and the vibration assembly is connected to the slide assembly through a clamp assembly, which improves automation and can adapt to multiple welding processes to improve the tensile strength and appearance consistency of the welding. At the same time, when replacing different parts to be welded 400 for welding, different ultrasonic vibration parameters can be adjusted according to the size and material differences of the products.

[0055] In some embodiments, the vibration mechanism 300 and the welding mechanism 200 are arranged on the same side of the workpiece 400 to be welded. This is beneficial for the vibration mechanism 300 to ensure that the pores in the weld are promptly released when the welding mechanism 200 welds the workpiece 400, and the weld structure is uniform and the particles are refined, thereby improving the weld quality.

[0056] In some embodiments, the vibration position of the vibration mechanism 300 moves in the same direction as the welding position of the welding mechanism 200. When the welding mechanism 200 welds the workpiece 400 to be welded, the vibration mechanism 300 can move along the distribution direction of the slide assembly to match the welding sequence of the welding mechanism 200 to achieve a better vibration effect. The vibration head 301 of the vibration mechanism 300 will cooperate from top to bottom with the side seam welding to improve the strength of the weld, avoid stress concentration near the pores in the weld and the tendency to cause cracks during product use, and achieve the purpose of optimizing the weld quality of the product.

[0057] In some embodiments, the vibration mechanism 300 and the welding mechanism 200 are configured to move independently.

[0058] Exemplarily, the vibration mechanism 300 and the welding mechanism 200 can be fixed on the same platform and then independently driven by different driving components to achieve independent movement of the two; in other embodiments, the vibration mechanism 300 and the welding mechanism 200 can also be fixed on different platforms and then switched and driven by the same driving component, or driven independently and reversely by different driving components.

[0059] In the technical solution of the embodiment of the present application, by independently moving the vibration mechanism and the welding mechanism, not only can a multi-pass welding process be realized and the optimal vibration position can be found based on the working condition of the welding mechanism, but corresponding compensation adjustments can also be made according to the weld gap, thereby improving the tensile strength of the weld.

[0060] Please refer to Figure 1 and Figure 2 The welding mechanism 200 includes a galvanometer assembly 201 and an air knife assembly 202. The air knife assembly 202 is connected to the galvanometer assembly 201. The galvanometer assembly 201 is configured to be used for welding the workpiece 400 to be welded, and the air knife assembly 202 is configured to be used for dust removal of the workpiece 400 to be welded; that is, when the welding mechanism 200 welds the end and side plates of the workpiece 400 to be welded, large-particle welding smoke and particles (Particle) with certain kinetic energy will be generated. For this reason, the air knife assembly 202 will be used for dust removal when laser welding the end plate and the side plate.

[0061] In some embodiments, the welding device further includes an industrial computer, which is respectively connected to the camera mechanism 100, the welding mechanism 200 and the vibration mechanism 300.

At the same time, the end plate of the workpiece 400 to be welded can be fastened by the electric cylinder, and its side plate is fitted under the push of the pneumatic cylinder, and then the electric cylinder returns to a position flush with the side plate. When the end plate is aligned with the side plate plane, it is in a weldable condition.

[0063] Specifically, the assembly equipment is first turned on, and the workpiece 400 to be welded is clamped by the clamping device. Then, the camera mechanism 100 identifies the weld gap between the end plate and the side plate of the clamped workpiece 400 to be welded. If the weld gap does not reach the weldable condition, the information is fed back to the clamping device for compensatory clamping. If the weld gap reaches the weldable condition at this time, the vibration mechanism 300 moves to align with the plate on one side of the weld and close to the workpiece 400 to be welded. The welding mechanism 200 emits a light beam to weld it, and the vibration head 301 of the vibration mechanism 300 also moves along the weld. After the welding is completed, the camera mechanism 100 is used again to take a picture of the weld appearance, and defects such as holes, length, width and cracks on the weld surface are detected. If there are defects, they flow into the NG position and wait for disassembly. If there are no defects, they flow into the next process for assembly.
