[0058] The turret-type cylindrical battery cap sealing and welding equipment provided by the present invention is described below with reference to Figures 1 to 7. The turret-type cylindrical battery cap sealing and welding equipment includes: a cell conveying line 1, a cover plate conveying line 2, a cap sealing mechanism 3, a welding mechanism 4, and a rejection mechanism 5.

[0059] In this embodiment, the battery cell conveying line 1 is disposed on one side of the cover closing mechanism 3, and the battery cell conveying line 1 is used to convey the battery cells to the cover closing mechanism 3. The cover plate conveying line 2 is disposed on one side of the cover closing mechanism 3, and the cover plate conveying line 2 is used to convey the cover plate to the cover closing mechanism 3.

[0060] As shown in Figures 2 to 4, the capping mechanism 3 includes a first turret 3110 and multiple capping devices 3200. The multiple capping devices 3200 are arranged sequentially at intervals along the circumference of the first turret 3110. During the rotation of the first turret 3110, the capping devices 3200 are used to press the cap onto the end of the battery cell to obtain a capped battery.

[0061] As shown in Figures 5 to 7, the sealing and welding mechanism 4 includes a welding device 43, a second turret 41, and multiple clamping devices 42. The multiple clamping devices 42 are arranged sequentially at intervals along the circumference of the second turret 41. During the rotation of the second turret 41, the welding device 43 is used to seal and weld the battery held by the clamping devices 42.

[0062] The rejection mechanism 5 is located on one side of the second turret 41. The rejection mechanism 5 is used to sort the sealed batteries and select the qualified batteries.

[0063] In the operation of the turret-type cylindrical battery cap-sealing and welding equipment provided by this invention, the cell conveying line 1 transports the cells to the cap-sealing mechanism 3, and the cover plate conveying line 2 transports the cover plates to the cap-sealing mechanism 3. During the rotation of the first turret 3110, the cap-sealing device 3200 presses the cover plates onto the ends of the cells to obtain a capped battery. The capped battery is then transferred to the clamping device 42. During the rotation of the second turret 41, the welding device 43 seals the battery held by the clamping device 42. After the battery is sealed, the rejection mechanism 5 sorts the sealed batteries, selecting the qualified ones.

[0064] This invention provides a turret-type cylindrical battery capping and sealing equipment. By setting up a cell conveyor line, a cover plate conveyor line, a capping mechanism, a sealing mechanism, and a rejection mechanism, the equipment not only utilizes the cell conveyor line to transport the cells to the capping mechanism and the cover plate conveyor line to transport the cover plates to the capping mechanism, but also, as the first turret rotates, it drives the various capping devices to rotate. The capping devices can press the cover plates onto the ends of the cells to obtain the capped battery. As the second turret rotates, it drives the various clamping devices to hold the batteries. A welding device is used to seal the batteries held by the clamping devices. Finally, the rejection mechanism is used to sort the sealed batteries. Therefore, this invention achieves simultaneous capping and subsequent sealing of multiple cells. The equipment has low investment costs and occupies little space. With the rotation of the first and second turrets, multiple capping devices and clamping devices can be sequentially processed along the circumference of the turrets, improving the production efficiency of the battery processing line.

[0065] In one example, as shown in Figures 1 to 4, the capping mechanism 3 is circumferentially equipped with a cell loading station, a cap loading station, and a cap unloading station. The cell conveyor line 1 is positioned opposite the cell loading station to load the capping device at the cell loading station. The cap conveyor line 2 is positioned opposite the cap loading station to load the capping device at the cap loading station. When the capping device 3200 is at the cap unloading station, it unloads the capped battery.

[0066] Specifically, during the rotation of the first turret 3110, the capping device 3200 rotates synchronously with the first turret 3110. When the capping device 3200 rotates to the cell loading station, the cell conveyor line 1 transports the cell to the capping device 3200. When the capping device 3200 rotates to the cover plate loading station, the cover plate conveyor line 2 transports the cover plate to the capping device 3200, whereby the capping device 3200 presses the cover plate onto the end of the cell to obtain the capped battery. After capping is completed, the capping device 3200 rotates to the capping unloading station, where it unloads the capped battery.

[0067] It should be noted that the turret-type cylindrical battery capping and sealing equipment also includes: a capping conveyor line 6 and a cup-holding conveyor line 7. The first end of the capping conveyor line 6 is positioned opposite the capping unloading station, and the second end is positioned opposite the sealing and welding mechanism 4. Thus, after the capping device 3200 unloads the capped battery, the capping conveyor line 6 can transfer the capped battery to the sealing and welding mechanism 4 for sealing. The cup-holding conveyor line 7 is used to transport the empty cups from the capping device 3200.

[0068] In another example, as shown in Figures 1 to 7, the sealing and welding mechanism 4 is provided with a cap-closing loading station, a welding station, and a cap-closing unloading station along the circumference. The clamping device 42 is used to clamp and control the rotation of the battery after the cap is closed.

[0069] The first end of the cap-closing conveyor line 6 is positioned opposite the cap-closing unloading station to carry the capped batteries. The second end of the cap-closing conveyor line 6 is positioned opposite the cap-closing loading station to load the clamping device 42 at the cap-closing loading station. The welding device 43 is positioned opposite the welding station to seal the batteries at the welding station. The rejection mechanism 5 is positioned opposite the sealing unloading station to sort the batteries at the sealing unloading station.

[0070] Specifically, during the rotation of the second turret 41, the clamping device 42 rotates synchronously with the second turret 41. When the clamping device 42 rotates to the capping and loading station, the capping conveyor line 6 transfers the capped batteries to the clamping device 42. When the clamping device 42 rotates to the welding station, the welding device 43 seals the batteries at the welding station. After the sealing is completed, the clamping device 42 rotates to the sealing and unloading station, where the rejection mechanism 5 sorts the batteries at the sealing and unloading station.

[0071] The second turret 41 is provided with a second upper turntable 412 and a second lower turntable 413. The second turret 41 can rotate relative to the second upper turntable 412 and the second lower turntable 413. The second upper turntable 412 is provided with a second upper boss 4120, and the second lower turntable 413 is provided with a second inner boss 4131 and a second outer boss 4132 arranged coaxially.

[0072] The second turret 41 includes a rotating component and a second upper turret 412 and a second lower turret 413 disposed on the rotating component. The rotating component can be a rotating shaft and can rotate relative to the second upper turret 412 and the second lower turret 413. During the rotation of the rotating component, the second upper turret 412 and the second lower turret 413 do not rotate. The second upper turret 412 is provided with a second upper boss 4120, which extends circumferentially along the second upper turret 412. The second lower turret 413 is provided with a second inner boss 4131 and a second outer boss 4132 coaxially arranged, both extending circumferentially along the second lower turret 413. The second inner boss 4131 is disposed within the second outer boss 4132.

[0073] The clamping device 42 includes a second base 421, a second pressing component 422, a second clamping component 423, and a second lifting component 424. The second base 421 is connected to the rotating component of the second turret. The second clamping component 423 is movably mounted on the second base 421 in the vertical direction, and its bottom abuts against the second inner boss 4131. The second lifting component 424 is movably mounted on the second base 421 in the vertical direction, and its bottom abuts against the second outer boss 4132. The second pressing component 422 is disposed opposite to the second lifting component 424. The second pressing component 422 is movably mounted on the second base 421 in the vertical direction, and its top abuts against the second upper boss 4120. A welding device 43 is disposed on one side of the clamping device 42 for welding the rotating battery.

[0074] Since the second base 421 is connected to the rotating component, during the rotation of the rotating component, the rotating component drives the second pressing component 422, the second clamping component 423 and the second lifting component 424 to rotate. The second pressing component 422 can slide on the second upper boss 4120, the second clamping component 423 can slide on the second inner boss 4131, and the second lifting component 424 can slide on the second outer boss. Thus, the second clamping component 423 can cooperate to clamp the battery, while the second lifting component 424 is used to lift the battery, and the second pressing component 422 presses the battery and drives the battery to rotate. Thus, the welding device 43 can be used to complete the welding of the rotating battery.

[0075] Specifically, after the battery is capped, it is transferred to the sealing welding device. At this time, the second lifting component 424 is lowered to a low position, the second pressing component 422 is raised to a high position, and the second clamping component 423 is raised to a high position to avoid the incoming material. After the battery is loaded, the second clamping component 423 lowers to a low position to clamp the battery, while the second lifting component 424 rises to a high position to support the battery. The second pressing component 422 then lowers to a low position to press the battery down. Under the clamping of the second clamping component 423 and the pressing of the second pressing component 422 and the second lifting component 424, the battery is fixed. At this time, the second pressing component 422 controls the battery to rotate, and the welding device 43 welds the rotating battery.

[0076] In one embodiment, as shown in Figures 1 to 7, the second inner boss 4131 is provided with a first protrusion and a second protrusion, the height of the first protrusion being greater than the height of the second protrusion; the second outer boss 4132 is provided with a third protrusion and a fourth protrusion, the height of the third protrusion being greater than the height of the fourth protrusion; and the second upper boss 4120 is provided with a fifth protrusion and a sixth protrusion, the height of the fifth protrusion being greater than the height of the sixth protrusion.

[0077] During the welding process of the welding device 43, the second clamping component 423 moves to the second protrusion to clamp the battery, the second lifting component 424 moves to the third protrusion to lift the battery, and the second pressing component 422 moves to the sixth protrusion to press down and drive the battery to rotate; during the non-welding process of the welding device 43, the second clamping component 423 moves to the first protrusion to release the battery, the second lifting component 424 moves to the fourth protrusion to put down the battery, and the second pressing component 422 moves to the fifth protrusion to move away from the battery.

[0078] To improve the welding efficiency of the sealing welding device, as shown in Figures 1 to 3, multiple clamping devices 42 are provided, and each clamping device 42 is arranged sequentially along the rotation direction of the second turret 41. The second pressing component 422 in each clamping device 42 is provided on the second upper boss 4120, the second clamping component 423 in each clamping device 42 is provided on the second inner boss 4131, and the second lifting component 424 in each clamping device 42 is provided on the second outer boss 4132.

[0079] When only one welding device 43 is set up, after the clamping device 42 of the first station aligns with the welding device 43, the corresponding second clamping component 423 moves to the second protrusion to clamp the battery, the second lifting component 424 moves to the third protrusion to lift the battery, and the second pressing component 422 moves to the sixth protrusion to press down and drive the battery to rotate. At this time, the welding device 43 is used to weld the rotating battery. During the welding process, the rotating component stops rotating. Meanwhile, the second clamping component 423 of the other clamping devices 42 moves to the first protrusion to release the battery, the second lifting component 424 moves to the fourth protrusion to lower the battery, and the second pressing component 422 moves to the fifth protrusion to move away from the battery. After the welding at the first station is completed, the rotating component continues to rotate, controlling the clamping device 42 of the second station to align with the welding device 43, and the welding device 43 can weld the battery at the second station. Repeating the above steps, the batteries on all clamping devices 42 can be welded.

[0080] As shown in Figure 7, the second base 421 is a supporting structure for the second pressing component 422, the second clamping component 423, and the second lifting component 424. The first side of the second base 421 is connected to the rotating component. The second side of the second base 421 opposite to the first side is provided with the second pressing component 422, the second clamping component 423, and the second lifting component 424, which are slidably mounted relative to the second base 421. The central axis of the second lifting component 424 coincides with the central axis of the second pressing component 422, and the clamping central axis of the second clamping component 423 is parallel to the central axis of the second lifting component. Since the second base 421 is connected to the rotating component, during the rotation of the rotating component, the rotating component drives the second pressing component 422, the second clamping component 423 and the second lifting component 424 to rotate. The second pressing component 422 can slide on the second upper boss 4120, the second clamping component 423 can slide on the second inner boss 4131, and the second lifting component 424 can slide on the second outer boss 4132. Thus, the second clamping component 423 can cooperate to clamp the battery, while the second lifting component 424 is used to lift the battery, and the second pressing component 422 presses the battery and drives the battery to rotate. Thus, the welding device 43 can be used to complete the welding of the rotating battery.

[0081] Based on the above embodiments, in one embodiment, as shown in FIG7, the second clamping assembly 423 includes: a second clamp 4231, a second support rod 4232, a first roller 4233, and a first driven wheel 4234. One end of the second clamp 4231 is provided with two clamping members spaced apart, the two clamping members being arranged on both sides of the central axis of the second lifting assembly 424, at least one clamping member being provided with a first driven wheel 4234 for abutting against the rotation of the battery, and the other end of the second clamp 4231 being provided on a second inner boss 4131 through the second support rod 4232 and the first roller 4233.

[0082] In this embodiment, both clamping members are provided with multiple first driven wheels 4234. The battery is clamped by the first driven wheels 4234, thereby maintaining the stability of the battery when controlling its rotation. The other end of the second clamp 4231 is connected to a second support rod 4232, and the bottom of the second support rod 4232 is provided with a first roller 4233, so that the first roller 4233 can move on the second inner boss 4131 during the rotation of the rotating component.

[0083] During the process of clamping the battery using the second clamping assembly 423, the first roller 4233 of the second clamping assembly 423 moves on the second inner boss 4131. When the first roller 4233 moves to the low position, the second clamp 4231 moves down, and the multiple first driven rollers 4234 on the second clamp 4231 clamp the battery. When the first roller 4233 moves to the high position, the second clamp 4231 moves up, thereby separating the second clamp 4231 from the battery.

[0084] Furthermore, the two clamping members on the second clamp 4231 are a first clamping member and a second clamping member, both of which are mounted on the connecting plate via corresponding pivots. The first and second clamping members are rotatable relative to the connecting plate. Simultaneously, a first guide rod is hinged to the first clamping member, and a second guide rod is hinged to the second clamping member. The first clamping member is connected to the second support rod 4232 via the first guide rod, and the second clamping member is connected to the second support rod 4232 via the second guide rod. A spring is connected to both the first clamping member and the second guide rod.

[0085] During the process of clamping the battery using the second clamping assembly 423, the first roller 4233 of the second clamping assembly 423 moves on the second inner boss 4131. When the first roller 4233 moves to the low position, the second clamp 4231 moves down, and the second support rod 4232 pulls the first clamping member through the first guide rod. The second support rod 4232 pulls the second clamping member through the second guide rod. At this time, the first guide rod and the second guide rod rotate relative to the second support rod 4232. During the rotation of the first guide rod and the second guide rod and the second support rod 4232, the spring rotates relative to the second support rod 4232. When the spring rotates to form an acute angle with the second support rod 4232, the spring pulls the first clamping member and the second clamping member closer together, and the first driven wheel 4234 on the two clamping members clamps the battery. After the second clamp 4231 moves upward, the first guide rod and the second guide rod rotate relative to the second support rod 4232, and the spring rotates relative to the second support rod 4232. When the spring rotates to be perpendicular to the second support rod 4232 or at another angle, the spring will spring the first clamping member and the second clamping member apart. At this time, the two clamping members open, so that the first driven wheel 4234 on the clamping member separates from the battery, thereby realizing the clamping and releasing of the battery and effectively ensuring the stability of the battery during sealing and welding.

[0086] To guide the movement of the second clamping assembly 423, a guide rail is provided on the second side of the second base 421, which is arranged vertically, and the second support rod 4232 is slidably mounted on the guide rail. By providing a guide rail that extends vertically, it can be ensured that the second clamping assembly 423 moves in the vertical direction.

[0087] Similarly, a guide rail for the second pressing component 422 can be provided on the second base 421. By providing a guide rail that extends vertically, the second pressing component 422 can be ensured to move in the vertical direction.

[0088] In addition, the sealing welding device also includes a second support plate 44 and a cup 45; the second support plate 44 is connected to the second base 421. The second support plate 44 has a first through hole. As shown in Figure 4, the second support plate 44 also has a second corner guard 46, which is used to limit the position of the cup 45, allowing the battery to be coaxial with the second pressing assembly 422 and the second lifting assembly 424. The second support plate 44 is connected to the second base 421, and the second corner guard 46 is located on the second support plate 44, on both sides of the central axis of the second lifting assembly. The second corner guard 46 is adapted to the shape of the cup 45 and is used to limit and fix the position of the cup 45. The bottom of the cup 45 has a second through hole, and the first and second through holes are coaxially arranged. The second driven wheel 4245, through the lifting and lowering of the second lifting rod, can pass through the first and second through holes in sequence to lift the battery in the cup.

[0089] In addition, to achieve more precise welding during the battery sealing process, optionally, to ensure a tighter fit between the cup 45 and the second corner protector 46, in this embodiment, a magnetic piece can be provided on the peripheral wall of the second corner protector 46, and the outer wall of the cup 45 can be provided with a material that attracts the magnetic piece, such as a metal or alloy material like iron, nickel, or cobalt. Conversely, the magnetic piece can also be provided on the cup, which will not be elaborated here.

[0090] In one embodiment, as shown in Figures 9 and 10, the second lifting assembly 424 includes: a lifting member, a second roller 4244, and a second driven roller 4245; one end of the lifting member is connected to the second driven roller 4245 for carrying the battery, and the bottom end of the lifting member is disposed on the second outer boss via the second roller 4244. The lifting member includes a second outer rod 4241, a second lifting rod 4242, and a second elastic member 4243; one end of the second outer rod 4241 is connected to the second driven roller 4245 for carrying the battery, the second outer rod 4241 is provided with the second elastic member 4243, the other end of the second outer rod 4241 is connected to the second elastic member 4243, the second elastic member 4243 is connected to the top end of the second lifting rod 4242, and the bottom end of the second lifting rod 4242 is disposed on the second outer boss 4132 via the second roller 4244.

[0091] Specifically, the top of the second outer sleeve rod 4241 is connected to a second inner support rod 4246, and the second inner support rod 4246 is equipped with a second driven wheel 4245, which directly supports the battery. The second outer sleeve rod 4241 is equipped with a second elastic element 4243, which can be a spring. The bottom end of the second outer sleeve rod 4241 is mounted on the second outer boss 4132 via the second elastic element 4243, the second lifting rod 4242, and the second roller 4244. During the rotation of the rotating component, the second roller 4244 can move on the second outer boss 4132. The second elastic element 4243 provides a certain amount of floating space for the entire second lifting assembly 424, preventing the battery from being damaged by pressure when lifting it.

[0092] To adjust the length of the entire second lifting assembly 424, a second inner support rod 4246 is slidably disposed within a second outer support rod 4241. The second inner support rod 4246 is connected to a second driven wheel 4245. A limiting groove is provided on the second outer support rod 4241, and a slider extending beyond the limiting groove is provided on the second inner support rod 4246. By moving the slider, the relative position between the second inner support rod 4246 and the second outer support rod 4241 can be adjusted, thereby adjusting the length of the second lifting assembly 424.

[0093] Based on the above embodiments, in one embodiment, as shown in FIG7, the second pressing assembly 422 includes: a second motor 4221, a second bearing seat 4222, a second pressing head 4223, and a second cam assembly 4224. The second motor 4221 is disposed on the second bearing seat 4222, which is movably connected to the second base 421 in the vertical direction. The second bearing seat 4222 is disposed on the second upper boss 4120 through the second cam assembly 4224. The rotating end of the second motor 4221 passes through the second bearing seat 4222 and is connected to the second pressing head 4223. The second pressing head 4223 is coaxially disposed with the second lifting assembly 424.

[0094] Specifically, the second bearing housing 4222 is movably connected to the second base 421 in the vertical direction. A second cam assembly 4224 is provided on the second bearing housing 4222, which is mounted on the second upper boss 4120. Thus, when the rotating component rotates, the second cam assembly 4224 moves on the second upper boss 4120, and the second bearing housing 4222 also moves. The second motor 4221 can be a servo motor, and the second pressure head 4223 is a copper pressure head. When the second motor 4221 rotates, it drives the copper pressure head to rotate. The copper pressure head has threads to prevent overheating during the battery's rotation. The copper pressure head and threads facilitate heat dissipation for the second pressure head 4223.

[0095] When the second pressing component 422 presses down, the second motor 4221 drives the second pressing head 4223 to rotate, and the battery can rotate under the drive of the second pressing head 4223. The rotation speed of the battery can be adjusted by controlling the rotation speed of the second motor 4221 to meet different welding needs.

[0096] Based on the above embodiments, in one embodiment, as shown in Figures 1 to 4, the first turret 3110 is provided with a first upper turntable 3120 and a first lower turntable 3130. The first turret 3110 can rotate relative to the first upper turntable 3120 and the first lower turntable 3130. The first upper turntable 3120 is provided with a first upper boss 3121, and the first lower turntable 3130 is provided with a first inner boss 3131 and a first outer boss 3132.

[0097] The first turret 3110 includes a rotating mechanism and a first upper turret 3120 and a first lower turret 3130 disposed on the rotating mechanism. The rotating mechanism can rotate relative to the first upper turret 3120 and the first lower turret 3130. The first upper turret 3120 is provided with a first upper boss 3121, and the first lower turret 3130 is provided with a first inner boss 3131 and a first outer boss 3132 coaxially disposed.

[0098] In this embodiment, the rotating mechanism may include a rotating shaft. The rotating mechanism is capable of rotating about the rotating shaft arranged in the vertical direction relative to the first upper turntable 3120 and the first lower turntable 3130. That is, during the rotation of the rotating mechanism, the first upper turntable 3120 and the first lower turntable 3130 do not rotate.

[0099] The closing device 3200 includes: a first base 3210, a first pressing component 3220, a first clamping component 3230, and a first lifting component 3240. The first base 3210 is fixedly connected to the rotating mechanism of the first turret. The first pressing component 3220, the first clamping component 3230, and the first lifting component 3240 are all movably connected to the first base 3210 in the vertical direction. The first pressing component 3220 can abut against the first upper boss 3121. The first clamping component 3230 is located below the first pressing component 3220 and its bottom can abut against the first inner boss 3131. The first lifting component 3240 is located below the first pressing component 3220 and its bottom can abut against the first outer boss 3132.

[0100] For the first pressing component 3220, the first pressing component 3220 can abut against the first upper boss 3121. Since the first upper turntable 3120 does not rotate with the rotating mechanism, the first pressing component 3220 will rotate along the circumferential direction of the rotating mechanism during the rotation of the rotating mechanism. At the same time, under the guidance of the first upper boss 3121, the first pressing component 3220 will move up and down in the vertical direction. For the first clamping component 3230 and the first lifting component 3240, the first clamping component 3230 can abut against the first inner boss 3131, and the first lifting component 3240 can abut against the first outer boss 3132. Since the first lower turntable 3130 does not rotate with the rotating mechanism, during the rotation of the rotating mechanism, the first clamping component 3230 and the first lifting component 3240 will both rotate along the circumferential direction of the rotating mechanism. At the same time, under the guidance of the first inner boss 3131 and the first outer boss 3132, the first clamping component 3230 and the first lifting component 3240 will also move up and down in the vertical direction.

[0101] In this embodiment, the first pressing component 3220 is used to obtain the cover plate and press it onto the end of the battery. For example, the first pressing component 3220 can obtain the cover plate by magnetic adsorption or negative pressure adsorption, or it can obtain the cover plate by gripping or snapping with the help of a motor or cylinder. It is understood that the first pressing component 3220 can be used to obtain the cover plate, and other methods can be used besides the above-mentioned methods. In addition, during the rotation of the rotating mechanism, the first clamping component 3230 can clamp the battery, and the first lifting component 3240 can lift the battery.

[0102] In practical applications, the cover plate and battery are respectively conveyed to the first turret 3110. Then, the first pressing component 3220 picks up the cover plate, and the battery is conveyed to the first lifting component 3240 and carried by it. During the rotation of the rotating mechanism, the first pressing component 3220 moves downward under the guidance of the first upper boss 3121. Simultaneously, the first clamping component 3230 gradually clamps the battery under the guidance of the first inner boss 3131, aligning the battery with the cover plate. Furthermore, the first lifting component 3240 lifts the battery upward under the guidance of the first outer boss 3132. Afterward, the first pressing component 3220 presses the cover plate onto the top of the battery, securing it to the top of the battery with an interference fit.

[0103] Furthermore, in order to ensure that the first upper boss 3121, the first inner boss 3131 and the first outer boss 3132 have sufficient guiding properties, in this embodiment, the first inner boss 3131 is provided with a first protrusion and a second protrusion, the height of the first protrusion being greater than the height of the second protrusion; the first outer boss 3132 is provided with a third protrusion and a fourth protrusion, the height of the third protrusion being greater than the height of the fourth protrusion; and the first upper boss 3121 is provided with a fifth protrusion and a sixth protrusion, the height of the fifth protrusion being greater than the height of the sixth protrusion.

[0104] During the process of securing the cover plate to the top of the battery, the first clamping assembly 3230 moves to the second protrusion to clamp the battery, the first lifting assembly 3240 moves to the third protrusion to lift the battery, and the first pressing assembly 3220 moves to the sixth protrusion to press the battery down. Before securing the cover plate to the top of the battery, the first clamping assembly 3230 moves to the first protrusion to release the battery, the first lifting assembly 3240 moves to the fourth protrusion to lower the battery, and the first pressing assembly 3220 moves to the fifth protrusion to move away from the battery.

[0105] It is understood that in this embodiment, for the first clamping component 3230, when the first clamping component 3230 abuts against the first protrusion of the first inner boss 3131, the first clamping component 3230 will not clamp the battery. As the rotating mechanism rotates, when the first clamping component 3230 abuts against the second protrusion of the first inner boss 3131, the first clamping component 3230 will move downward in the vertical direction and be able to clamp the battery. For the first lifting component 3240, when the first lifting component 3240 abuts against the third protrusion of the first outer boss 3132, the first lifting component 3240 will lift the battery to a higher position. As the rotating mechanism rotates, when the first lifting component 3240 abuts against the fourth protrusion of the first outer boss, the first lifting component 3240 will move downward in the vertical direction and lower the battery to a lower position. For the first pressing component 3220, when the first pressing component 3220 abuts against the sixth protrusion of the first upper boss 3121, the first pressing component 3220 will press the cover plate down to a lower position that can press against the top of the battery. As the rotating mechanism rotates, the first pressing component 3220 will move upward in the vertical direction. When the first pressing component 3220 abuts against the fifth protrusion of the first upper boss 3121, the first pressing component 3220 will completely separate from the cover plate and move away from the cover plate.

[0106] In practical applications, when the cover is fixed to the top of the battery, the first clamping component 3230 abuts against the second protrusion and can clamp the battery, the first lifting component 3240 abuts against the third protrusion and can lift the battery, and the first pressing component 3220 abuts against the sixth protrusion and can press down the battery. At this time, the cover is pressed against the top of the battery.

[0107] When the cover is not fixed to the top of the battery, the first clamping assembly 3230 abuts against the first protrusion and can release the battery, the first lifting assembly 3240 abuts against the fourth protrusion and can lower the battery, and the first pressing assembly 3220 abuts against the fifth protrusion and can move away from the battery.

[0108] It is understood that in this embodiment, the second protrusion of the first inner boss 3131, the third protrusion of the first outer boss 3132, and the sixth protrusion of the first upper boss 3121 are positioned correspondingly, thereby enabling the pressing of the cover plate and the battery. The first protrusion of the first inner boss 3131, the fourth protrusion of the first outer boss 3132, and the fifth protrusion of the first upper boss 3121 are positioned correspondingly, thereby enabling the battery cover to be closed and facilitating the movement of the closed battery to the next processing station.

[0109] Furthermore, in the battery production line, it is necessary to continuously press the cover plate onto the top of the battery. In order to improve the efficiency of battery pressing, in this embodiment, multiple cover-closing devices 3200 are provided, and each cover-closing device 3200 is arranged sequentially at intervals along the rotation direction of the first turret 3110.

[0110] In practical applications, the cover plates conveyed to the first turret 3110 can be picked up one by one by the first pressing component 3220, and the batteries conveyed to the first turret can be carried one by one by the first lifting component 3240. As the rotating mechanism continues to rotate, under the guidance of the first upper boss 3121, the first inner boss 3131 and the first outer boss 3132, the cover plates and batteries can be pressed together one by one and continuously by the closing device 3200, thereby effectively ensuring the production efficiency of battery pressing.

[0111] In this embodiment, the first pressing component 3220 can move up and down under the guidance of the first upper boss 3121, and the first pressing component 3220 can obtain the cover plate.

[0112] To achieve the above functions, as shown in Figures 2 to 4, the first pressing component 3220 includes: a first pressing head 3221, a first cam assembly 3222, and a first mounting base 3223. The first mounting base 3223 is movably connected to the first base 3210 in the vertical direction. The first pressing head 3221 and the first cam assembly 3222 are oppositely arranged and both connected to the first mounting base 3223. The first cam assembly 3222 can abut against the first upper boss 3121, and the first pressing head 3221 can obtain the cover plate.

[0113] In related technologies, the top of the cover plate is usually provided with a roughly cylindrical groove. In order to achieve accurate positioning of the cover plate, as shown in Figures 2, 3, 4 and 11, the first pressure head 3221 includes a metal pressure block, which is connected to the first mounting base 3223. The bottom of the metal pressure block facing the first lifting assembly 3240 is provided with a flange for positioning the groove on the top of the cover plate.

[0114] Therefore, when the first pressing assembly 3220 obtains the cover plate, the flange on the metal pressing block can engage with the groove on the top of the cover plate, thereby achieving the positioning of the cover plate and ensuring the accuracy of the mutual pressing between the cover plate and the battery.

[0115] For example, the metal pressure block can be a copper pressure block to avoid scratching the cover plate and to facilitate heat dissipation of the first pressure head 3221.

[0116] Furthermore, to improve production efficiency and simplify control, in this embodiment, the first pressing component 3220 is used to pick up the cover plate and press it onto the top of the battery. For example, the first pressing component 3220 can pick up the cover plate using magnetic force or negative pressure.

[0117] In related technologies, cover plates are usually made of metal materials. In this embodiment, the first pressure head 3221 can obtain the cover plate by means of magnetic adsorption.

[0118] Specifically, as shown in Figures 2, 3, 4 and 11, the first pressing head 3221 includes a high-temperature magnet, which is embedded in the bottom of the metal pressing block and located at the center of the flange. The bottom surface of the high-temperature magnet does not extend beyond the bottom surface of the metal pressing block.

[0119] In practical applications, when the metal cover plate is conveyed to the first turret 3110, the magnetic attraction between the cover plate and the high-temperature magnet can effectively ensure that the first pressure head 3221 obtains the cover plate. Moreover, the high-temperature magnet is located at the center of the flange, and its bottom surface does not exceed the bottom surface of the metal pressure block, which can ensure the positioning effect of the flange on the cover plate. At the same time, it can also make the attraction force of the high-temperature magnet on the cover plate more balanced.

[0120] After the cover plate is pressed onto the battery, it is fixed to the top of the battery due to the interference fit between the cover plate and the battery. At this time, the magnetic attraction force of the high-temperature magnet on the cover plate is insufficient to separate the cover plate from the battery. As the rotating mechanism rotates, the first pressing head 3221 will move away from the cover plate under the guidance of the first upper boss 3121. For example, in order to reduce the number of control steps, the high-temperature magnet can be a permanent magnet.

[0121] Furthermore, in the process of pressing the cover plate onto the battery, in addition to positioning the cover plate, it is also necessary to position the top of the battery. In this embodiment, as shown in Figures 2 and 3, the first pressing head 3221 includes a battery guide block. The battery guide block is annular and surrounds the periphery of the metal pressing block. The battery guide block has guide protrusions for positioning the battery at its bottom facing the first lifting assembly 3240.

[0122] In practical applications, when the first pressure head 3221 drives the cover plate to press against the battery, the guide protrusion on the battery guide block will move to the periphery of the top of the battery, thereby positioning the top of the battery.

[0123] Furthermore, to improve the battery positioning effect and avoid interference with the connection between the cover and the battery, in this embodiment, the battery guide block is movably connected to the metal pressure block in the vertical direction. The bottom of the metal pressure block is provided with a limiting block to restrict the downward movement of the battery guide block. A first elastic element 3224 is provided between the top of the battery guide block and the first mounting base 3223. For example, the first elastic element 3224 can be a spring.

[0124] In practical applications, when the first pressing head 3221 drives the cover plate to press against the battery, the guide protrusion of the battery guide block can initially position the top of the battery. As the first pressing component 3220 and the first lifting component 3240 approach each other, the top of the battery is fully positioned by the guide protrusion, and the top of the battery abuts against the bottom of the battery guide block. Then, under the abutment limit of the battery, the battery guide block moves upward relative to the metal pressing block, the first elastic element 3224 is compressed, and the cover plate gradually reaches the pressing position of the top of the battery, achieving a pressing connection. Afterwards, as the first pressing component 3220 gradually moves away from the battery, under the elastic driving action of the first elastic element 3224, the battery guide block gradually returns to the initial position limited by the limiting block.

[0125] In addition, the first pressure head 3221 can also be connected to a pressure sensor, which can accurately sense the force between the cover and the battery during the pressing process.

[0126] Optionally, in order to ensure that the first pressing component 3220 can move stably, the first base 3210 may also be provided with a guide rail extending in the vertical direction on the side near the first pressing component, and the first mounting base 3223 can be slidably connected to the guide rail.

[0127] Furthermore, after the battery is delivered to the first turret 3110, in order to ensure that the subsequent first clamping assembly 3230 can effectively clamp the battery, the battery needs to be initially positioned. In this embodiment, as shown in Figures 2 to 4, the turret-type cylindrical battery cap sealing and welding equipment also includes: a first support plate 3251 and a first corner protector 3252.

[0128] The first support plate 3251 is connected to the first base 3210. The first corner guard 3252 is disposed on the first support plate 3251 and located on both sides of the central axis of the first lifting assembly 3240. The first corner guard 3252 is adapted to the shape of the battery and is used to limit and fix the position of the battery.

[0129] In practical applications, after the battery is delivered to the first turret 3110, it can be placed on the first support plate 3251, with the inner side of the battery abutting against the first corner protector 3252. Since the first corner protector 3252 is located on both sides of the central axis of the first lifting assembly 3240, and the shape of the first corner protector 3252 is adapted to the shape of the battery, the first corner protector 3252 can limit and fix the position of the battery. For example, the first corner protector 3252 can limit the battery's position and allow the battery to be coaxial with the first pressing assembly 3220 and the first lifting assembly 3240.

[0130] In this embodiment, when the rotating mechanism rotates, the first clamping assembly 3230 can move up and down in the vertical direction under the guidance of the first inner boss 3131, thereby clamping the battery.

[0131] To achieve the above functions, in a specific embodiment, as shown in Figure 3, the first clamping assembly 3230 includes: a third clamping member 3231, a fourth clamping member 3232, a first connecting seat 3233, and a first support rod 3234. The first connecting seat 3233 is fixedly connected to the first base 3210, and the first connecting seat 3233 is also provided with a slide rail extending in the horizontal direction. The third clamping member 3231 and the fourth clamping member 3232 are both slidably connected to the slide rail. At the same time, the third clamping member 3231 and the fourth clamping member 3232 are respectively located on both sides of the central axis of the first lifting assembly 3240.

[0132] To facilitate battery clamping, at least one of the third clamping member 3231 and the fourth clamping member 3232 is provided with a driven wheel, which can directly abut against the battery to achieve battery clamping.

[0133] For example, the third clamping member 3231 may be provided with two sets of driven wheels that can rotate around the vertical direction, and the fourth clamping member 3232 may be provided with one set of driven wheels that can rotate around the vertical direction. With the help of these three sets of driven wheels, the battery can be clamped and the battery can be rotated around a rotation axis that extends in the vertical direction.

[0134] The bottom end of the first support rod 3234 is provided with a third roller 3235, which can abut against the first inner boss 3131. The top end of the first support rod 3234 is connected to a third guide rod 3236 and a fourth guide rod 3237. The third guide rod 3236 and the fourth guide rod 3237 are located on both sides of the central axis of the first lifting assembly 3240. The third guide rod 3236 corresponds to the third clamping member 3231, and the two ends of the third guide rod 3236 are respectively hinged to the first support rod 3234 and the third clamping member 3231. The fourth guide rod 3237 corresponds to the fourth clamping member 3232, and the two ends of the fourth guide rod 3237 are respectively hinged to the first support rod 3234 and the fourth clamping member 3232.

[0135] In this embodiment, the first support rod 3234 can drive the third clamping member 3231 and the fourth clamping member 3232 to move on the slide rail of the first connecting seat 3233 during the up and down movement.

[0136] In practical applications, when the first support rod 3234 moves upward, it increases the angle between the third guide rod 3236 and the fourth guide rod 3237, causing the third clamping member 3231 and the fourth clamping member 3232 to move away from each other. When the first support rod 3234 moves downward, it decreases the angle between the third guide rod 3236 and the fourth guide rod 3237, causing the third clamping member 3231 and the fourth clamping member 3232 to move closer together, thus clamping the battery.

[0137] Furthermore, to ensure that the third clamping member 3231 and the fourth clamping member 3232 can apply sufficient clamping force to the battery, the first clamping assembly 3230 further includes an elastic fastener 3238, which can apply a force to the third clamping member 3231 and the fourth clamping member 3232 respectively, so that they can move closer to each other. For example, the elastic fastener 3238 can be a spring. Exemplarily, as shown in FIG3, in this embodiment, the elastic fastener 3238 can be provided between the third clamping member 3231 and the fourth guide rod 3237 so that the third clamping member 3231 can move closer to the fourth clamping member 3232. The elastic fastener 3238 can also be provided between the fourth clamping member 3232 and the first base 3210 so that the fourth clamping member 3232 can move closer to the third clamping member 3231.

[0138] In practical applications, when the battery is clamped by the first clamping component 3230, the third roller 3235 at the bottom of the first support rod 3234 moves on the first inner boss 3131. When the third roller 3235 moves to the low position, the first support rod 3234 moves downward. At this time, the third guide rod 3236 and the fourth guide rod 3237 both rotate relative to the first support rod 3234, and the included angle between them becomes smaller. At the same time, under the pulling action of the elastic fastener 3238, the third clamping component 3231 and the fourth clamping component 3232 move closer to each other on the slide rail of the first connecting seat 3233, thereby clamping the battery.

[0139] When the third roller 3235 gradually moves to the high position of the first inner boss 3131, the first support rod 3234 moves upward, and both the third guide rod 3236 and the fourth guide rod 3237 rotate relative to the first support rod 3234, and the included angle between them increases. At the same time, the elastic fastener 3238 is stretched, and the third clamping member 3231 and the fourth clamping member 3232 move away from each other on the slide rail of the first connecting seat 3233, thereby releasing the battery. Thus, through the above structure, the first clamping assembly 3230 can clamp and release the battery, effectively ensuring the stability of the battery when the cover is closed.

[0140] Optionally, in order to guide the movement of the first clamping assembly 3230, the first base 3210 is provided with a guide rail extending in a vertical direction on the side near the first support rod 3234, and the first support rod 3234 is slidably connected to the guide rail.

[0141] In this embodiment, when the rotating mechanism rotates, the first lifting component 3240 can move up and down in the vertical direction under the guidance of the first outer protrusion 3132, thereby lifting the battery.

[0142] To achieve the above functions, in a specific embodiment, as shown in Figures 2, 3, 4 and 11, the first lifting assembly 3240 includes: a first lifting rod 3241, a first support platform 3242 and a fourth roller 3243.

[0143] The first support platform 3242 is connected to the top of the first lifting rod 3241 and is used to support the battery. The fourth roller 3243 is connected to the bottom of the first lifting rod 3241 and is used to abut against the first outer protrusion 3132.

[0144] In this embodiment, the battery can be placed on the first support plate 3251. To facilitate the lifting of the battery by the first lifting assembly 3240, the first support plate 3251 is provided with a through hole extending vertically, and the first support platform 3242 is placed in the through hole. Optionally, the top of the first support platform 3242 does not extend beyond the top surface of the first support plate 3251.

[0145] In practical applications, after the battery is placed on the first support plate 3251, when the battery needs to be lifted by the first lifting component 3240, the fourth roller 3243 at the bottom of the first lifting rod 3241 can move on the first outer protrusion 3132. When the fourth roller 3243 gradually moves to the high position of the first outer protrusion 3132, the first lifting rod 3241 moves upward, and the first support platform 3242 can lift the battery to the highest position.

[0146] When the battery needs to be lowered using the first lifting assembly 3240, the fourth roller 3243 gradually moves to the low position of the first outer protrusion 3132, the first lifting rod 3241 moves downward, and the first support platform 3242 can lower the battery onto the first support plate 3251.

[0147] Therefore, through the above structure, the first lifting component 3240 can lift and lower the battery, effectively ensuring the stability of the battery when the cover is closed.

[0148] Furthermore, during the pressing process between the cover and the battery, sufficient buffer space needs to be reserved for the movement of the battery to avoid damaging the equipment and the battery.

[0149] In this embodiment, the first lifting rod 3241 includes an upper support rod, an inner sleeve rod, and a lower support rod. The bottom end of the upper support rod is connected to the top end of the lower support rod, and the bottom end of the lower support rod is connected to the fourth roller 3243. The upper support rod has a hollow tubular structure with a buffer spring inside its cavity. The inner sleeve rod is inserted into the cavity of the upper support rod, and its top end is connected to the first support platform 3242. The two ends of the buffer spring abut against the bottom end of the inner sleeve rod and the top end of the lower support rod, respectively.

[0150] Therefore, by setting a buffer spring, when the first lifting component 3240 lifts the battery, it can provide a certain buffer space for the height position of the battery, which can prevent the battery from being damaged by pressure.

[0151] Optionally, in order to facilitate the adjustment of the length of the entire first lifting assembly 3240, the upper support rod is provided with a threaded hole, and the inner sleeve rod is provided with a limiting groove extending in its axial direction. The bolt can be threaded to the threaded hole of the upper support rod and abut against the limiting groove of the inner sleeve rod. The bolt can effectively limit the relative position between the upper support rod and the inner sleeve rod.

[0152] Therefore, by adjusting the relative position between the upper support rod and the inner sleeve rod, and by fixing the upper support rod and the inner sleeve rod with bolts, the length of the entire first lifting assembly 3240 can be easily adjusted.

[0153] Based on the above embodiments, in another embodiment, as shown in FIG1, the rejection mechanism 5 includes a visual sorting component 51, a defective product rejection conveyor line 52, and a good product conveyor line 53.

[0154] The vision sorting component 51 is located on one side of the sealing and welding mechanism 4, corresponding to the location of the sealing and welding unloading station, to perform visual inspection on the semi-finished batteries that have been sealed and welded; if the semi-finished battery is a defective product, the vision sorting component 51 will transport the defective product to the defective product rejection conveyor line 52; if the semi-finished battery is a qualified product, the vision sorting component 51 will transport the qualified product to the good product conveyor line 53.

[0155] Specifically, the visual sorting component 51 may include a first transfer tray, a sorting tray, a second transfer tray, a third transfer tray, and a visual inspection component.

[0156] The first transfer tray is located at the sealing and unloading station of the sealing and welding mechanism. The vision inspection component is located above the first transfer tray. The first transfer tray is connected to the sorting tray, which is connected to the second and third transfer trays respectively. The second transfer tray is connected to one end of the defective product rejection conveyor line 52, and the third transfer tray is connected to one end of the good product conveyor line 53. The vision inspection component includes an industrial camera.

[0157] In practical applications, the first transfer tray receives the semi-finished batteries that have been sealed. During the process of the first transfer tray conveying the semi-finished batteries toward the sorting tray, the vision inspection component collects the sealing images and judges the sealing quality of the upper end of the battery cell based on the sealing images.

[0158] Thus, when the visual inspection component determines that the semi-finished battery is a defective product, the sorting tray will transport the defective product to the second transfer tray, and then the second transfer tray will transport the defective product to the defective product rejection conveyor line 52, so that the defective product rejection conveyor line 52 can centrally transport and store the defective products.

[0159] When the visual inspection component determines that the semi-finished battery is a qualified product, the sorting tray transports the qualified product to the third transfer tray, and then the third transfer tray transports the qualified product to the good product conveyor line 53, so that the good product conveyor line 53 can centrally transport and store the qualified product.

[0160] Furthermore, according to an embodiment of the present invention, a method for processing batteries using the turret-type cylindrical battery cap sealing and welding equipment as described above is also provided, as shown in FIG12, the method comprising:

[0161] Step S1: The cell conveying line transports the cells to the cover closing mechanism, and the cover plate conveying line transports the cover plate to the cover closing mechanism.

[0162] Step S2: After the battery cell and cover plate are transferred to the closing mechanism, the closing device presses the cover plate onto the end of the battery cell under the control of the rotation of the first turret, so as to obtain the closed battery.

[0163] Step S3: After the battery with the cover closed is transferred to the sealing and welding mechanism, the welding device is used to seal and weld the battery held by the clamping device under the control of the rotation of the second turret.

[0164] Step S4: After the sealed batteries are transferred to the rejection mechanism, the rejection mechanism sorts the sealed batteries.

[0165] Specifically, during the rotation of the first turret 3110, the capping device 3200 rotates synchronously with the first turret 3110. When the capping device 3200 rotates to the cell loading station, the cell conveyor line 1 conveys the cell to the capping device 3200. When the capping device 3200 rotates to the cover plate loading station, the cover plate conveyor line 2 conveys the cover plate to the capping device 3200, thereby pressing the cover plate onto the end of the cell to obtain the capped battery. After capping is completed, the capping device 3200 rotates to the capping unloading station, where it can unload the capped battery. During the rotation of the second turret 41, the clamping device 42 rotates synchronously with the second turret 41. When the clamping device 42 rotates to the capping loading station, the capping conveyor line 6 transfers the capped battery to the clamping device 42. When the clamping device 42 rotates to the welding station, the welding device 43 seals the battery at the welding station. After the sealing is completed, the clamping device 42 rotates to the sealing and unloading station, and the rejection mechanism 5 sorts the batteries at the sealing and unloading station. During the sorting process of the rejection mechanism 5, when the visual inspection component determines that the semi-finished battery is a qualified product, the sorting tray transports the qualified product to the third transfer tray, and then the third transfer tray transports the qualified product to the good product conveyor line 53, so that the good product conveyor line 53 can centrally transport and store the qualified products.

[0166] The method for processing batteries using the turret-type cylindrical battery cap sealing and welding equipment in this embodiment utilizes the rotation of the first and second turrets to sequentially process multiple cap sealing devices and clamping devices along the circumference of the turrets, thereby improving the production efficiency of the battery processing line. Furthermore, a rejection mechanism is subsequently included for sorting, ensuring the processing quality of the batteries.
