[0043] See Figure 1 、Figure 2 , Figure 3 , Figure 4 , an ultrasonic welding dust removal device for a battery cell tab provided by an embodiment of the present application includes an ultrasonic welder 1. One side of the ultrasonic welder 1 is connected to a welding head 2, and a welding base 3 is arranged below the welding head 2. A dust suction head 5 is connected to the ultrasonic welder 1 through a lifting mechanism 4. The dust suction head 5 is arranged adjacent to the welding head 2. A retaining groove 6 is arranged around the welding base 3. The dust suction head 5 and the retaining groove 6 are respectively communicated with a dust suction assembly 7.

[0044] The ultrasonic welding dust removal device for a battery cell tab provided by an embodiment of the present application is used for dust removal during the ultrasonic welding process of the battery cell tab. The specific welding dust removal process is as follows: Place the battery cell tab on the welding base 3, and the ultrasonic welder 1 drives the welding head 2 to press down to perform ultrasonic welding on the battery cell tab. During this process, the lifting mechanism 4 drives the dust suction head 5 to descend synchronously with the downward pressing of the welding head 2. The dust suction assembly 7 sucks away the dust and particulate matter generated during the welding process through the dust suction head 5. The dust and particulate matter not sucked away by the dust suction head 5 fall into the retaining groove 6 around the welding base 3 and are sucked away by the dust suction assembly 7 again.

[0045] The ultrasonic welding dust removal device for a battery cell tab provided by an embodiment of the present application arranges the dust suction head 5 adjacent to the welding head 2, and the lifting mechanism 4 can drive the dust suction head 5 to lift and lower synchronously with the welding head 2, so that the distance between the dust suction point and the dust generation point is closer. Thus, the dust and particulate matter generated during the welding process can be sucked away by the dust suction assembly 7 in time, greatly improving the dust removal effect. By arranging a retaining groove 6 communicated with the dust suction assembly 7 around the welding base 3, it is used to collect the dust and particulate matter not sucked away by the dust suction head 5 in the retaining groove 6 and suck them away through the dust suction assembly 7, further improving the dust removal effect. Compared with the prior art, the dust removal effect of the present application is better, ensuring the cleanliness of the working environment, improving the welding quality and product quality, and protecting the health of operators at the same time.

[0046] The retaining groove 6 is used to collect the dust and particulate matter that fall during the ultrasonic welding process. Among them, the retaining groove 6 may include a circle of side walls arranged around the welding base 3. The lower end of the side wall is hermetically connected to the welding base 3. A dust suction port is arranged at the bottom of the retaining groove 6. The dust suction assembly 7 is communicated with the dust suction port. The dust suction assembly 7 is used to suck away the dust and particulate matter collected in the retaining groove 6. Of course, the retaining groove 6 may also be other existing structures, which are not specifically limited herein.

[0047] In some embodiments, refer to Figure 1 , Figure 2, the side wall of the retaining groove 6 has an inclined section 8 that slopes outward from bottom to top, and the welding base 3 penetrates through the inclined section 8. Exemplarily, the inclined section 8 has a welding base hole for the welding base 3 to pass through, and the welding base 3 passes through this welding base hole so that the upper end of the welding base 3 is located above the inclined section 8. By providing the inclined section 8, during the ultrasonic welding process of the battery cell tab, the dust and particulate matter not sucked away by the suction head 5 first fall on the inclined section 8, then slide down to the bottom of the retaining groove 6 under the action of gravity and accumulate together, and then are sucked away by the suction assembly 7.

[0048] In some embodiments, referring to Figure 1 , Figure 3 , the suction assembly 7 is connected to the suction head 5 through a first pipe 9, and the suction assembly 7 is connected to the retaining groove 6 through a second pipe 10. This structure is simple to install and convenient to operate. During the ultrasonic welding process of the battery cell tab, the suction assembly 7 not only sucks away the dust and particulate matter at the dust generation point through the first pipe 9 and the suction head 5, but also sucks away the dust and particulate matter collected in the retaining groove 6 through the second pipe 10. In other embodiments, the suction assembly 7 can also be connected to the suction head 5 and the retaining groove 6 through other structures, which are not specifically limited herein.

[0049] In some embodiments, referring to Figure 1 , Figure 3 , the first pipe 9 and the second pipe 10 are respectively flexible hoses. Flexible hoses are easy to bend and convenient to arrange in narrow on-site spaces. Exemplarily, the first pipe 9 and the second pipe 10 are respectively PVC steel wire hoses. PVC steel wire hoses can not only withstand high negative pressure, are suitable for vacuum cleaners to suck dust and particulate matter, but also have a small bending radius and are convenient to use in narrow spaces.

[0050] The suction assembly 7 can include a negative pressure fan, a vacuum pump, etc. In some embodiments, referring to Figure 1 , Figure 2 , the suction assembly 7 includes a pneumatic vacuum cleaner. The pneumatic vacuum cleaner uses compressed air as a power source. Since there are no moving parts, it can work continuously for a long time without overheating, the equipment requires little maintenance, and the noise during operation is small, providing a more comfortable working environment. When in use, the pneumatic vacuum cleaner sucks in and temporarily stores the dust and particulate matter generated during the welding process. The staff needs to regularly clean the foreign objects stored in the pneumatic vacuum cleaner to ensure the stable operation of the equipment.

[0051] In some embodiments, referring to Figure 1 , Figure 3 , the lifting mechanism 4 is connected to the welding head 2 through a connecting member. The lifting mechanism 4 can include an electric push rod, a linear motor, a cylinder or a hydraulic cylinder. The connecting member can include a connecting plate, a connecting rod and a connecting block, etc.

[0052] Exemplarily, the connecting member includes a first cross bar 11, a first vertical bar 12, and a second cross bar 13.

Among them, the first cross bar 11 is connected to the lifting mechanism 4 through fasteners such as bolts, and the second cross bar 13 is connected to the dust suction head 5 through fasteners such as bolts. Both the first cross bar 11 and the second cross bar 13 are horizontally arranged, the first vertical bar 12 is vertically arranged, and the first cross bar 11, the first vertical bar 12, and the second cross bar 13 are sequentially connected to form a connecting member substantially in a Z shape, and this structure can reduce the occupied installation space.

[0053] In some embodiments, the cell pole ear ultrasonic welding dust removal device provided by the embodiments of the present application further includes a controller, and the controller is respectively connected to the ultrasonic welding machine 1 and the dust suction assembly 7. By providing the controller, the ultrasonic welding machine 1 and the dust suction assembly 7 can be synchronously controlled. For example, when the ultrasonic welding machine 1 is in the welding state, the controller controls the dust suction assembly 7 to be in the dust suction state; when the ultrasonic welding machine 1 is in the non-welding state, the controller controls the dust suction assembly 7 to be in the closed state, thereby achieving an energy-saving effect.

[0054] In some embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , the cell pole ear ultrasonic welding dust removal device provided by the embodiments of the present application further includes a platform plate 14, and both the ultrasonic welding machine 1 and the welding seat 3 are connected to the platform plate 14. Exemplarily, the platform plate 14 is horizontally arranged, the ultrasonic welding machine 1 is installed on the platform plate 14, and the welding seat 3 is connected to the platform plate 14 through an L-shaped connecting plate 15. For example, the L-shaped connecting plate 15 includes a horizontal section and a vertical section connected to the horizontal section. The horizontal section of the L-shaped connecting plate 15 is supported on the platform plate 14 and fixed by bolts. The lower end of the welding seat 3 is fixedly connected to the horizontal section, and the retaining groove 6 is fixedly connected to the vertical section. Of course, in other embodiments, the welding seat 3 and the retaining groove 6 may also be fixedly connected to the ultrasonic welding machine 1.
