For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The cylindrical battery cell production line according to an embodiment of the utility model is described below with reference to the accompanying drawings.

[0033] Reference Figure 1 The cylindrical battery cell production line of the embodiment of the utility model includes a frame 100, an arrangement mechanism, a welding mechanism, a conductive strip conveying mechanism and a battery cell conveying mechanism.

[0034] Reference Figure 1 and Figure 2 As for the arrangement mechanism, the arrangement mechanism is arranged on the frame 100, and the arrangement mechanism includes a first conveyor belt 110 and an arrangement trough 120. A baffle plate 130 is arranged at the discharge end of the first conveyor belt 110, and the baffle plate 130 is used to limit the battery cells on the first conveyor belt 110. The arrangement trough 120 is arranged on one side of the discharge end of the first conveyor belt 110. The first conveyor belt 110 is provided with a first cylinder 140 for pushing the battery cells on the first conveyor belt 110 one by one to the arrangement trough 120. A second cylinder 150 is arranged at the feed end of the arrangement trough 120, and the second cylinder 150 is used to push the battery cells in the arrangement trough 120 to be arranged neatly.

[0035] It can be understood that the battery cells are input into the first conveyor belt 110, and the first conveyor belt 110 drives the battery cells to be transported to the discharge end of the first conveyor belt 110, and the baffle plate 130 limits the battery cells to prevent the battery cells from escaping from the first conveyor belt 110, and then the first cylinder 140 pushes the battery cells one by one into the arrangement trough 120, and then the second cylinder 150 pushes the battery cells in the arrangement trough 120 to be arranged neatly, so that the battery cells on the arrangement trough 120 can be moved to the welding mechanism to weld the conductive strips at the same time, thereby improving production efficiency. In addition, the number of battery cells pushed to the arrangement trough 120 by the first cylinder 140 can be controlled to control the number of battery cells arranged in the arrangement trough 120 each time.

[0036] In some specific embodiments, a limiting rod 430 is provided at the discharge end of the arrangement slot 120, and the limiting rod 430 is used to limit the battery cells in the arrangement slot 120, thereby preventing the battery cells from escaping from the arrangement slot 120 from the discharge end of the arrangement slot 120 during arrangement.

[0037] Furthermore, a slide groove is provided at the discharge end of the arrangement trough body 120, and the slide groove accommodates the lifting and lowering of the limit rod 430. An eighth cylinder 440 is also provided at the bottom of the arrangement trough body 120, and the eighth cylinder 440 is used to drive the lifting and lowering of the limit rod 430. The limit rod 430 is lifted and lowered to block or avoid the battery cell.

[0038] It can be understood that when the battery cells are arranged on the arrangement slot 120, the eighth cylinder 440 drives the limit rod 430 to rise and protrude from the arrangement slot 120, so that the limit rod 430 can limit the battery cells. When the battery cell conveying mechanism transfers the battery cells on the arrangement slot 120, the eighth cylinder 440 drives the limit rod 430 to descend into the arrangement slot 120, thereby facilitating the limit rod 430 to avoid the battery cells.

[0039] Reference Figure 1 and Figure 3 As for the welding mechanism, the welding mechanism is arranged on the frame 100, and the welding mechanism is located on the side of the arrangement slot body 120 close to the discharge end, and the welding mechanism is used to weld the conductive strip to the battery cell.

[0040] Specifically, the welding mechanism includes a welding gun 210 and a translation assembly 220 that drives the welding gun 210 to approach and move away from the battery cell along the length direction of the battery cell. Therefore, when the battery cell moves to a position where welding is required, the translation assembly 220 drives the welding gun 210 close to welding. When the battery cell is moving without welding, the translation assembly 220 can drive the welding gun 210 away from the battery cell, thereby enabling the welding mechanism to accurately weld the battery cell.

[0041] Furthermore, the translation assembly 220 includes a first translation seat 230, a third cylinder 240 that drives the first translation seat 230 to translate, a buffer seat 250 that is slidably connected to the first translation seat 230, and a buffer spring 260 that is arranged between the first translation seat 230 and the buffer seat 250. The buffer seat 250 is located on the side of the first translation seat 230 close to the battery cell, and the welding gun 210 is installed on the buffer seat 250.

[0042] It can be understood that when the third cylinder 240 drives the first translation seat 230 to approach the battery cell, after the welding gun 210 abuts the battery cell, the buffer seat 250 can compress the buffer spring 260, so that the welding gun 210 can be buffered, avoiding the welding gun 210 from colliding hard with the battery cell to damage the battery cell or the welding gun 210.

[0043] Reference Figure 1 and Figure 4 As for the conductive bar conveying mechanism, the conductive bar conveying mechanism is arranged on the frame 100, and the conductive bar conveying mechanism is located between the arrangement slot body 120 and the welding mechanism. The conductive bar conveying mechanism includes a guide bar 160, a conveying assembly 170 and a cutting assembly 180. The guide bar 160 is provided with a guide groove 161. The discharge end of the guide groove 161 is located at the feed end of the welding mechanism. The guide groove 161 is used to guide the movement of the conductive bar. The conveying assembly 170 is used to convey the conductive bar. The cutting assembly 180 is located at the discharge end of the guide groove 161. The cutting assembly 180 is used to cut the conductive bar.

[0044] It can be understood that the conductive strip can be accurately transported to the welding mechanism by the conveying component 170 after being guided by the wire groove. Then, the cutting component 180 can cut the conductive strip according to the needs of the welding process, so that the cut conductive strip can be welded between two battery cells. Therefore, the conductive strip conveying mechanism can continuously transport the conductive strip to the welding mechanism, thereby improving production efficiency.

[0045] In some specific embodiments, the guide bar 160 is provided with an avoidance groove 270 that transversely penetrates the guide groove 161, and the avoidance groove 270 is used to accommodate the conveying component 170 to abut against the conveying conductive bar, so that there are partial guide grooves 161 in front and behind the conveying component 170 to guide the conductive bar, thereby making the movement of the conductive bar smoother.

[0046] In some specific embodiments, the conveying assembly 170 includes a first conveying wheel 280, a first motor 290 that drives the first conveying wheel 280 to rotate, a mounting base 300, a second conveying wheel 310 that is rotatably disposed on the mounting base 300, and a fourth cylinder 320 that drives the mounting base 300 to approach and move away from the first conveying wheel 280. The first conveying wheel 280 and the second conveying wheel 310 clamp and convey the conductive strip.

[0047] It can be understood that when the conveying component 170 needs to convey the conductive strip, the fourth cylinder 320 drives the mounting seat 300 close to the first conveying wheel 280, so that the first conveying wheel 280 and the second conveying wheel 310 clamp and convey the conductive strip; when the conveying component 170 needs to stop conveying the conductive strip, the fourth cylinder 320 drives the mounting seat 300 away from the first conveying wheel 280, so that the first conveying wheel 280 and the second conveying wheel 310 release the conductive strip, thereby facilitating the conveying component 170 to convey the conductive strip at intervals.

[0048] In some specific embodiments, the cutting assembly 180 includes a cutter 330 and a fifth cylinder 340 that drives the cutter 330 to approach or move away from the battery cell. The cutter 330 is used to cut the conductive strips, so that the cutting assembly 180 can cut the guide strips 160 at intervals.

[0049] In some specific embodiments, the conductive strip conveying mechanism further includes a material tray rotatably disposed on the frame 100, the material tray is used to support the unwinding of the rolled conductive strip, and the rolled conductive strip on the material tray is used for feeding.

[0050] In some specific embodiments, two welding mechanisms are provided, and the two welding mechanisms are respectively located at the two ends of the battery cell. The two welding mechanisms respectively weld the conductive strips to the positive electrode and the negative electrode of the battery cell. Two conductive strip conveying mechanisms are correspondingly provided, and one conductive strip conveying mechanism conveys the conductive strip to one welding mechanism.

[0051] Reference Figure 1 and Figure 5 As for the battery cell transfer mechanism, the battery cell transfer mechanism is arranged on the frame 100, and the battery cell transfer mechanism includes a suction seat 190 and a transfer assembly 200 for driving the suction seat 190 to move. The bottom of the suction seat 190 has a plurality of positioning grooves 191. The suction seat 190 is used to adsorb the battery cell in the positioning groove 191, and the transfer assembly 200 is used to transfer the suction seat 190 from the top of the arrangement slot body 120 through the welding mechanism.

[0052] It can be understood that by setting a plurality of positioning grooves 191 at the bottom of the suction seat 190, each positioning groove 191 can position a battery cell, so that the suction seat 190 can simultaneously absorb multiple groups of battery cells and transfer them to the welding mechanism for connection welding, thereby reducing the frequency of the battery cell transfer mechanism going back and forth between the arrangement slot body 120 and the welding mechanism, thereby improving production efficiency.

[0053] In some specific embodiments, the material suction seat 190 includes a first seat body 350, a first material plate 360 ​​arranged under the first seat body 350, a sixth cylinder 370 that drives the first material plate 360 ​​to rise and fall, and a first magnet 380 arranged at the bottom of the first seat body 350. The positioning groove 191 is located at the bottom of the first material plate 360. The sixth cylinder 370 drives the first material plate 360 ​​to rise and fall close to or away from the first magnet 380 so that the first magnet 380 adsorbs or releases the battery cell in the positioning groove 191.

[0054] It can be understood that when the suction seat 190 absorbs the battery cell, the sixth cylinder 370 drives the first material plate 360 ​​to rise and fit the first magnet 380, so that the first magnet 380 is close to the battery cell in the positioning groove 191, so that the magnetic force of the first magnet 380 can absorb the battery cell in the positioning groove 191; when the suction seat 190 needs to remove the material, the sixth cylinder 370 drives the first material plate 360 ​​to descend away from the first magnet 380, so that the first magnet 380 is away from the battery cell in the positioning groove 191, and the battery cell can automatically detach from the positioning groove 191 and fall after losing the magnetic attraction of the first magnet 380.

[0055] In some specific embodiments, the transfer assembly 200 includes a second translation seat 390 slidably disposed on the frame 100, a first screw rod 400 that drives the second translation seat 390 to translate, a lifting seat 410 that slides up and down on the second translation seat 390, and a seventh cylinder 420 that drives the lifting seat 410 to rise and fall. The suction seat 190 is disposed on the lifting seat 410, so that the transfer assembly 200 can drive the suction seat 190 to rise and fall and translate, thereby making the movement of the suction seat 190 more flexible.

[0056] Furthermore, a second motor is disposed on the frame 100 , and the second motor is used to drive the first screw rod 400 to rotate.

[0057] In some specific embodiments, a second conveyor belt is provided at the discharge end of the welding mechanism, and the battery cell transfer mechanism can transfer the battery cells to the second conveyor belt, and the second conveyor belt is used to transport the discharged battery cells.
