[0028] See attached Figure 1 As shown, an embodiment of the present application provides a battery tab welding device, which includes a base 1, on which a feeding mechanism 2 is provided, and the feeding mechanism 2 is used to automatically feed batteries, and a jig with multiple batteries is placed manually or by external equipment on the feeding mechanism 2. Multiple batteries and connecting pieces to be welded are placed on the jig.

[0029] The end of the feeding mechanism 2 is provided with a welding mechanism 100, such as Figure 2 As shown, the welding mechanism 100 includes a transmission mechanism 4, which is used to drive the fixture 200 and thus drive the battery to move to the bottom of the pressing mechanism 6. The upper and lower positions of the transmission mechanism 4 are adjustable, and the transmission mechanism 4 has two states, namely, an upper state and a lower state. When the transmission mechanism 4 is in the upper state, it can drive the fixture 200 to transmit. When the connecting piece on the battery needs to be pressed or welded, the transmission mechanism 4 is lowered to the lower position, and the fixture 200 can be placed on the positioning mechanism 5.

[0030] A positioning mechanism 5 for positioning the jig 200 is disposed on the side of the transmission mechanism 4 . The positioning mechanism 5 is used to position the jig 200 to prevent the jig 200 from being misplaced and causing low welding accuracy.

[0031] A pressing mechanism 6 for pressing the product 300 is disposed above the transmission mechanism 4. The pressing mechanism 6 is used to press the connecting piece to prevent the welding precision from being low due to the misalignment of the connecting piece. An up-and-down moving mechanism 7 for driving the pressing mechanism 6 to move up and down is disposed on one side of the pressing mechanism 6. A welding assembly 8 for welding the product 300 is disposed above the pressing mechanism 6. The welding assembly 8 is used to weld the battery tab and the connecting piece together.

[0032] The battery tab welding device also includes a controller, and the feeding mechanism 2, the transmission mechanism 4, the up and down moving mechanism 7 and the welding assembly 8 are electrically connected to the controller respectively.

[0033] The present application can automatically load materials and drive the batteries and connecting pieces to be welded to the welding assembly 8, and can realize automatic welding, thereby improving the welding efficiency and the safety factor, and preventing the operator from getting burned. The pressing mechanism 6 in the present application can press the connecting piece to prevent the connecting piece from being misplaced, thereby improving the welding accuracy and making the battery welding consistent.

[0034] On the basis of the above, if Figure 3 As shown, the feeding mechanism 2 includes a first fixed frame 201, and a first transmission assembly is arranged on the first fixed frame 201. The first transmission assembly includes a driving wheel 202, a driven wheel 203, and a transmission belt 204 arranged on the outer surface of the driving wheel 202 and the driven wheel 203. A first motor 205 that drives the driving wheel 202 to rotate is arranged on one side of the driving wheel 202. A first sensor 206 for detecting whether there is a fixture 200 at a specified position of the transmission belt 204 is arranged at one end of the first fixed frame 201 away from the transmission mechanism 4. The first sensor 206 is used to detect whether there is a jig 200 at a specified position on the transmission belt 204. When the first sensor 206 detects that there is a jig 200 at the specified position of the transmission belt 204, that is, when it detects that the jig 200 is placed on the transmission belt 204, the controller controls the first motor 205 to rotate, and the first motor 205 rotates to drive the driving wheel 202 to rotate, and the driving wheel 202 rotates to drive the driven wheel 203 to rotate and drive the transmission belt 204 to transmit, thereby driving the jig 200 to transmit.

[0035] On the basis of the above, if Figure 4As shown, the transmission mechanism 4 includes a second fixed frame 401, on which a second transmission assembly 402 for driving the fixture 200 is arranged, the second transmission assembly 402 includes a second driving wheel, a second driven wheel and a second transmission belt arranged on the outer surfaces of the second driving wheel and the second driven wheel, a second motor for driving the second driving wheel to rotate is arranged on one side of the second driving wheel, and a second up-and-down moving assembly 403 for driving the second fixed frame 401 to move up and down is arranged on one side of the second fixed frame 401 on the base 1. The second up-and-down moving assembly 403 is used to drive the second transmission assembly 402 to move up and down.

[0036] The second transmission component 402 has two states, namely an upper state and a lower state. When the jig 200 needs to be driven for transmission, the second transmission component 402 is in the upper state. When the connecting piece on the battery needs to be pressed or welded, the second transmission component 402 descends to the lower state, so that the jig 200 can be placed on the positioning mechanism 5.

[0037] The width of the jig 200 is greater than the width of the positioning mechanism 5 . The jig 200 is located above the positioning mechanism 5 . When the second transmission assembly 402 drives the jig 200 to descend, the jig 200 can be supported on the positioning mechanism 5 .

[0038] Working principle:

[0039] When the jig 200 needs to be transmitted, the second transmission assembly 402 is in the upper position, and the second transmission assembly 402 drives the jig 200 to transmit. When the jig 200 is transmitted to the specified position, the second up and down moving assembly 403 drives the second transmission assembly 402 to descend to the lower position. At this time, the jig 200 is placed on the positioning mechanism 5.

The height of the plane where the positioning posts 502 are located is higher than the height of the upper end of the second transmission assembly 402 when it is in the lower position, so that the fixture can be supported on the positioning mechanism when the second transmission assembly is in the lower position. Through holes are arranged at positions corresponding to the positioning posts 502 on the fixture 200, and the circular holes are sleeved on the outer surface of the positioning posts 502 during the descent of the fixture 200 to achieve the positioning of the fixture 200.

The width of the connecting plate 602 is greater than the width of the pressing plate 601, so that the connecting plate 602 can be supported on the up-and-down moving mechanism 7, so that it can move up and down under the drive of the up-and-down moving mechanism 7.

[0042] like Figure 7 As shown, through holes are provided at positions corresponding to the positions where the product needs to be welded on the pressing plate 601 and the connecting plate 602, and a plurality of connecting seats 604 are provided on the connecting plate 602, and each connecting seat 604 is connected to a pressing strip 605, one end of the pressing strip 605 is connected to the connecting seat 604, and the other end of the pressing strip 605 is provided with a pressing ring 606, and the pressing ring 606 is located in the through hole, and the pressing ring 606 is a hollow ring structure. The pressing ring 606 can be pressed to the connection between the tab and the connecting piece under the drive of the up-and-down moving mechanism 7.

[0043] On the basis of the above, the connecting seat 604 and the pressing strip 605 are connected through the connecting block 607, and the connecting block 607 is fixedly connected to the pressing strip 605. The connecting block 607 is connected to one side of the connecting seat 604 by sliding rails and sliders for up and down sliding. A guide column 608 is arranged on the connecting seat 604 above the connecting block 607, and a spring 609 is sleeved on the outer surface of the guide column 608. The two ends of the spring 609 are respectively connected to the connecting block 607 and the connecting seat 604, which can buffer the downward pressing force of the pressing strip 605 driven by the up and down moving mechanism 7, and prevent the connection from being pressed and deformed.

[0044] On the basis of the above, if Figure 8 As shown, the welding assembly 8 includes a laser head 801, an up-and-down moving module 802 for driving the laser head 801 to move up and down, a forward-and-backward moving module 803 for driving the laser head 801 to move forward and backward, and a left-and-right moving module 804 for driving the laser head 801 to move left and right. The laser head 801 is used to weld the connecting piece and the battery tab. During welding, the laser head 801 extends into the pressing ring 606 to weld the battery tab and the connecting piece together.

The third sensor 405 is used to detect whether there is a jig 200 at the head end of the second transmission component 402, that is, to detect whether the jig 200 is transmitted to the second transmission component 402. When the third sensor 405 detects that there is a jig 200 at the head end of the second transmission component 402, a signal is sent to the controller, and the controller controls the second transmission component 402 to start working and drive the jig 200 to transmit. The second sensor is used to detect whether the jig 200 moves to the specified position at the end of the second transmission component 402.

[0046] On the basis of the above, if Figure 5 As shown, a blocking mechanism 406 for blocking the transmission of the jig 200 is provided at the end of the second transmission assembly 402. The blocking mechanism 406 includes a baffle and a third up-and-down moving assembly for driving the baffle to move up and down. When the jig 200 is transmitted to a specified position at the end of the second transmission assembly 402, the third up-and-down moving assembly drives the baffle to move upward to block the jig 200, preventing the jig 200 from moving, and also positioning the jig 200.
