[0002] The battery manufacturing process involves multiple steps. With the rapid development of the power battery industry, higher demands are being placed on battery manufacturing efficiency.

[0003] In battery manufacturing, closing the battery cover requires fixing the cover plate to the top of the battery. In existing technologies, the cover plate needs to be moved to the top of the battery, then controlled to move towards the battery, so that the cover plate closes to the top of the battery, and then the cover plate is pre-spot welded to the edge of the battery casing. However, the above-mentioned existing cover closing and pre-spot welding steps require corresponding equipment for the cover plate and the battery, including a feeding mechanism, a centering mechanism, and a pre-spot welding mechanism. In particular, the laser welding process has high requirements for its process precision. In addition, the more equipment used, the higher the cost, the lower the battery production efficiency, and the larger the space occupied, making it difficult to meet the site requirements and also affecting the construction of the entire production line.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0036] In one embodiment of the present invention, a turret-type cylindrical battery capping device is provided. This device includes a turret and a capping mechanism. The turret receives a cap and a battery, and the capping mechanism presses the cap onto the top of the battery, ensuring the pressing accuracy between the cap and the battery. Furthermore, the capping mechanism continuously presses the cap onto the top of the battery during the rotation of the turret's rotating mechanism, thereby improving battery production efficiency. The following is a related description... Figures 1-4 The turret-type cylindrical battery cover device in this embodiment is described in further detail.

[0037] Specifically, such as Figures 1 to 4 As shown, the battery pressing device in this embodiment includes a turret 100 and a cover closing mechanism 200.

[0038] The turret 100 includes a rotating mechanism 110 and an upper turntable 120 and a lower turntable 130 disposed on the rotating mechanism 110. The rotating mechanism 110 can rotate relative to the upper turntable 120 and the lower turntable 130. The upper turntable 120 is provided with an upper boss 121, and the lower turntable 130 is provided with an inner boss 131 and an outer boss 132 arranged coaxially.

[0039] For example, in this embodiment, the rotating mechanism 110 may include a rotating shaft. The rotating mechanism 110 is capable of rotating about the rotating shaft arranged in the vertical direction relative to the upper turntable 120 and the lower turntable 130. That is, during the rotation of the rotating mechanism 110, the upper turntable 120 and the lower turntable 130 do not rotate.

[0040] The upper boss 121 extends circumferentially along the upper turntable 120, and the inner boss 131 and the outer boss 132 both extend circumferentially along the lower turntable 130, with the inner boss 131 located inside the outer boss 132.

[0041] The closing mechanism 200 includes a base 210, a pressing component 220, a clamping component 230, and a lifting component 240. The base 210 is fixedly connected to the rotating mechanism 110. The pressing component 220, the clamping component 230, and the lifting component 240 are all movably connected to the base 210 in the vertical direction. The pressing component 220 can abut against the upper boss 121. The clamping component 230 is located below the pressing component 220 and its bottom can abut against the inner boss 131. The lifting component 240 is located below the pressing component 220 and its bottom can abut against the outer boss 132.

[0042] For example, in this embodiment, the base 210 can be fixedly connected to the rotating mechanism 110 by means of bolts or the like, and the rotating mechanism 110 can drive the base 210 to rotate synchronously when it rotates.

[0043] Furthermore, the pressing component 220, the clamping component 230, and the lifting component 240 are connected to the base 210. When the rotating mechanism 110 rotates, the pressing component 220, the clamping component 230, and the lifting component 240 will also rotate synchronously with the rotating mechanism 110.

[0044] The pressing assembly 220, the clamping assembly 230, and the lifting assembly 240 are all movably connected to the base 210 in the vertical direction.

[0045] Specifically, the pressing component 220 can abut against the upper boss 121. Since the upper turntable 120 does not rotate with the rotating mechanism 110, the pressing component 220 will rotate along the circumferential direction of the rotating mechanism 110 during the rotation of the rotating mechanism 110. At the same time, under the guidance of the upper boss 121, the pressing component 220 will move up and down in the vertical direction. For the clamping assembly 230 and the lifting assembly 240, the clamping assembly 230 can abut against the inner boss 131, and the lifting assembly 240 can abut against the outer boss 132. Since the lower turntable 130 does not rotate with the rotating mechanism 110, during the rotation of the rotating mechanism 110, both the clamping assembly 230 and the lifting assembly 240 will rotate along the circumferential direction of the rotating mechanism 110. At the same time, under the guidance of the inner boss 131 and the outer boss 132, the clamping assembly 230 and the lifting assembly 240 will also move up and down in the vertical direction.

[0046] In this embodiment, the pressing component 220 is used to obtain the cover plate and press it onto the end of the battery. For example, the pressing component 220 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 pressing component 220 can be used to obtain the cover plate, and other methods can be used besides the above-mentioned methods.

[0047] In addition, during the rotation of the rotating mechanism 110, the clamping component 230 can clamp the battery, and the lifting component 240 can lift the battery.

[0048] In practical applications, the cover plate and battery are conveyed to the turret 100. The pressing assembly 220 then picks up the cover plate, while the battery is conveyed to the lifting assembly 240 and carried by it. During the rotation of the rotating mechanism 110, the pressing assembly 220 moves downwards under the guidance of the upper boss 121. Simultaneously, the clamping assembly 230, guided by the inner boss 131, gradually clamps the battery, aligning its position with the cover plate. Meanwhile, the lifting assembly 240, guided by the outer boss 132, lifts the battery upwards. Afterwards, the pressing assembly 220 presses the cover plate onto the top of the battery, securing it to the top of the battery with an interference fit.

[0049] Therefore, by using the turret-type cylindrical battery cover device in this embodiment, the cover plate can be accurately pressed onto the top of the battery, thereby ensuring the automated production of the battery.

[0050] Furthermore, in order to ensure that the upper boss 121, the inner boss 131 and the outer boss 132 have sufficient guiding properties, in this embodiment, the inner boss 131 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 outer boss 132 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 upper boss 121 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.

[0051] During the process of securing the cover plate to the top of the battery, the clamping assembly 230 moves to the second protrusion to clamp the battery, the lifting assembly 240 moves to the third protrusion to lift the battery, and the pressing assembly 220 moves to the sixth protrusion to press the battery down. Before securing the cover plate to the top of the battery, the clamping assembly 230 moves to the first protrusion to release the battery, the lifting assembly 240 moves to the fourth protrusion to lower the battery, and the pressing assembly 220 moves to the fifth protrusion to move away from the battery.

[0052] It is understood that in this embodiment, for the clamping component 230, when the clamping component 230 abuts against the first protrusion of the inner boss 131, the clamping component 230 will not clamp the battery. As the rotating mechanism 110 rotates, when the clamping component 230 abuts against the second protrusion of the inner boss 131, the clamping component 230 will move downward in the vertical direction and be able to clamp the battery. For the lifting component 240, when the lifting component 240 abuts against the third protrusion of the outer boss 132, the lifting component 240 will lift the battery to a higher position. As the rotating mechanism 110 rotates, when the lifting component 240 abuts against the fourth protrusion of the outer boss, the lifting component 240 will move downward in the vertical direction and lower the battery to a lower position. As for the pressing component 220, when the pressing component 220 abuts against the sixth protrusion of the upper boss 121, the pressing component 220 will press the cover plate down to a lower position that can press against the top of the battery. As the rotating mechanism 110 rotates, the pressing component 220 will move upward in the vertical direction. When the pressing component 220 abuts against the fifth protrusion of the upper boss 121, the pressing component 220 will completely separate from the cover plate and move away from the cover plate.

[0053] In practical applications, when the cover is fixed to the top of the battery, the clamping component 230 abuts against the second protrusion and can clamp the battery, the lifting component 240 abuts against the third protrusion and can lift the battery, and the pressing component 220 abuts against the sixth protrusion and can press down the battery. At this time, the cover is pressed against the top of the battery.

[0054] When the cover is not secured to the top of the battery, the clamping assembly 230 abuts against the first protrusion and can release the battery, the lifting assembly 240 abuts against the fourth protrusion and can lower the battery, and the pressing assembly 220 abuts against the fifth protrusion and can move away from the battery.

[0055] It is understood that in this embodiment, the second protrusion of the inner boss 131, the third protrusion of the outer boss 132, and the sixth protrusion of the upper boss 121 are positioned correspondingly, thereby enabling the pressing of the cover plate and the battery. The first protrusion of the inner boss 131, the fourth protrusion of the outer boss 132, and the fifth protrusion of the upper boss 121 are positioned correspondingly, thereby enabling the battery cover to be closed and facilitating the movement of the closed battery to the next processing station.

[0056] Furthermore, in the battery production line, the cover plate needs to be continuously pressed onto the top of the battery. To improve the efficiency of battery pressing, in this embodiment, as follows: Figure 1 As shown, there are multiple closing mechanisms 200, and each closing mechanism 200 is arranged sequentially at intervals along the rotation direction of the turret 100.

[0057] In practical applications, the cover plates conveyed to the turret 100 can be picked up one by one by the pressing component 220, and the batteries conveyed to the turret can be carried one by one by the lifting component 240. As the rotating mechanism 110 continues to rotate, under the guidance of the upper boss 121, the inner boss 131 and the outer boss 132, the cover plates and batteries can be pressed together one by one and continuously by the closing mechanism 200, thereby effectively ensuring the production efficiency of battery pressing.

[0058] In this embodiment, the pressing component 220 can move up and down under the guidance of the upper boss 121, and the pressing component 220 can obtain the cover plate.

[0059] In order to achieve the above functions, such as Figures 2 to 4 As shown, the pressing assembly 220 includes a pressing head 221, a cam assembly 222, and a mounting base 223. The mounting base 223 is movably connected to the base 210 in the vertical direction. The pressing head 221 and the cam assembly 222 are arranged opposite to each other and are both connected to the mounting base 223. The cam assembly 222 can abut against the upper boss 121, and the pressing head 221 can obtain the cover plate.

[0060] 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, such as... Figures 2 to 4 As shown, the pressure head 221 includes a metal pressure block 2211, which is connected to the mounting base 223. The metal pressure block 2211 has a flange facing the bottom of the lifting assembly 240 for positioning the groove on the top of the cover plate.

[0061] Therefore, when the pressing assembly 220 obtains the cover plate, the flange on the metal pressing block 2211 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.

[0062] For example, the metal pressure block 2211 can be a copper pressure block to avoid scratching the cover plate and to facilitate heat dissipation of the pressure head 221.

[0063] Furthermore, to improve production efficiency and simplify control, in this embodiment, the pressing assembly 220 is used to pick up the cover plate and press it onto the top of the battery. For example, the pressing assembly 220 can pick up the cover plate using magnetic force or negative pressure.

[0064] In related technologies, cover plates are usually made of metal materials. In this embodiment, the pressure head 221 can obtain the cover plate by means of magnetic adsorption.

[0065] Specifically, such as Figures 2 to 4 As shown, the pressure head 221 includes a high-temperature magnet 2212, which is embedded in the bottom of the metal pressure block 2211 and located at the center of the flange. The bottom surface of the high-temperature magnet 2212 does not extend beyond the bottom surface of the metal pressure block 2211.

[0066] In practical applications, when the metal cover plate is conveyed to the turret 100, the magnetic attraction between the cover plate and the high-temperature magnet 2212 can effectively ensure that the pressure head 221 obtains the cover plate. Moreover, the high-temperature magnet 2212 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 2212 on the cover plate more balanced.

[0067] After the cover plate is pressed onto the battery, the cover plate can be fixed on 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 2212 on the cover plate is insufficient to separate the cover plate from the battery. As the rotating mechanism 110 rotates, under the guidance of the upper boss 121, the pressure head 221 will move away from the cover plate.

[0068] For example, in order to reduce control steps, the high-temperature magnet can be a permanent magnet.

[0069] Furthermore, during 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 follows... Figures 2 to 3 As shown, the pressure head 221 includes a battery guide block 2213, which is constructed in a ring shape. The battery guide block 2213 is connected to the periphery of the metal pressure block 2211. The battery guide block 2213 is provided with a guide protrusion for positioning the battery facing the bottom of the lifting assembly 240.

[0070] In practical applications, when the pressure head 221 drives the cover plate to press against the battery, the guide protrusion on the battery guide block 2213 will move to the periphery of the top of the battery, thereby positioning the top of the battery.

[0071] 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 2213 is movably connected to the metal pressure block 2211 in the vertical direction. The bottom of the metal pressure block 2211 is provided with a limiting block to restrict the downward movement of the battery guide block 2213. An elastic element 224 is provided between the top of the battery guide block 2213 and the mounting base 223. For example, the elastic element 224 can be a spring.

[0072] In practical applications, when the pressure head 221 drives the cover plate to press against the battery, the guide protrusion of the battery guide block 2213 can initially position the top of the battery. As the pressing component 220 and the lifting component 240 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 2213. Then, under the abutment limit of the battery, the battery guide block 2213 moves upward relative to the metal pressure block 2211, the elastic element 224 is compressed, and the cover plate gradually reaches the pressing position of the top of the battery, achieving a pressing connection. Afterwards, as the pressing component 220 gradually moves away from the battery, under the elastic driving action of the elastic element 224, the battery guide block 2213 gradually returns to the initial position limited by the limiting block.

[0073] In addition, the pressure head 221 can also be connected to a pressure sensor, which can accurately sense the force between the cover and the battery during the pressing process.

[0074] Optionally, in order to ensure that the pressing component 220 can move stably, the base 210 may also be provided with a guide rail extending in the vertical direction on the side near the pressing component, and the mounting base 223 can be slidably connected to the guide rail.

[0075] Furthermore, after the battery is delivered to the turret 100, in order to ensure that the subsequent clamping assembly 230 can effectively clamp the battery, preliminary positioning of the battery is required. In this embodiment, for example... Figures 2 to 4 As shown, the turret-type cylindrical battery cover device also includes: a support plate 251 and a corner protector 252.

[0076] The support plate 251 is connected to the base 210, and the corner guards 252 are set on the support plate 251, located on both sides of the central axis of the lifting assembly 240. The corner guards 252 are adapted to the shape of the battery and are used to limit and fix the position of the battery.

[0077] In practical applications, after the battery is delivered to the turret 100, it can be placed on the support plate 251, and the inner side of the battery can abut against the corner protector 252. Since the corner protector 252 is located on both sides of the central axis of the lifting assembly 240, and the shape of the corner protector 252 is adapted to the battery, the corner protector 252 can limit and fix the position of the battery.

[0078] For example, the corner protector 252 can limit the battery and allow the battery to be coaxial with the pressing component 220 and the lifting component 240.

[0079] In this embodiment, when the rotating mechanism 110 rotates, the clamping assembly 230 can move up and down in the vertical direction under the guidance of the inner boss 131, thereby clamping the battery.

[0080] To achieve the above functions, in a specific embodiment, such as Figure 3 As shown, the clamping assembly 230 includes: a first clamping member 231, a second clamping member 232, a connecting seat 233, and a support rod 234. The connecting seat 233 is fixedly connected to the base 210, and the connecting seat 233 is also provided with a slide rail extending in the horizontal direction. The first clamping member 231 and the second clamping member 232 are both slidably connected to the slide rail. At the same time, the first clamping member 231 and the second clamping member 232 are respectively arranged on both sides of the central axis of the lifting assembly 240.

[0081] To facilitate battery clamping, at least one of the first clamping member 231 and the second clamping member 232 is provided with a driven wheel, which can directly abut against the battery to achieve battery clamping.

[0082] For example, the first clamping member 231 may be provided with two sets of driven wheels that can rotate around the vertical direction, and the second clamping member 232 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.

[0083] The bottom end of the support rod 234 is provided with a first roller 235, which can abut against the inner boss 131. The top end of the support rod 234 is connected to a first guide rod 236 and a second guide rod 237. The first guide rod 236 and the second guide rod 237 are located on both sides of the central axis of the lifting assembly 240. The first guide rod 236 corresponds to the first clamping member 231, and the two ends of the first guide rod 236 are respectively hinged to the support rod 234 and the first clamping member 231. The second guide rod 237 corresponds to the second clamping member 232, and the two ends of the second guide rod 237 are respectively hinged to the support rod 234 and the second clamping member 232.

[0084] In this embodiment, the support rod 234 can drive the first clamping member 231 and the second clamping member 232 to move on the slide rail of the connecting seat 233 during the up and down movement.

[0085] In practical applications, when the support rod 234 moves upward, it increases the angle between the first guide rod 236 and the second guide rod 237, causing the first clamping member 231 and the second clamping member 232 to move away from each other. When the support rod 234 moves downward, it decreases the angle between the first guide rod 236 and the second guide rod 237, causing the first clamping member 231 and the second clamping member 232 to move closer together, thereby clamping the battery.

[0086] Furthermore, to ensure that the first clamping member 231 and the second clamping member 232 can apply sufficient clamping force to the battery, the clamping assembly 230 further includes an elastic fastener 238, which can apply a force to the first clamping member 231 and the second clamping member 232 respectively, so that they can move closer to each other. For example, the elastic fastener 238 can be a spring.

[0087] For example, such as Figure 3 As shown, in this embodiment, an elastic fastener 238 may be provided between the first clamping member 231 and the second guide rod 237, so that the first clamping member 231 can approach the second clamping member 232. An elastic fastener 238 may also be provided between the second clamping member 232 and the base 210, so that the second clamping member 232 can approach the first clamping member 231.

[0088] In practical applications, when the battery is clamped using the clamping assembly 230, the first roller 235 at the bottom of the support rod 234 moves on the inner boss 131. When the first roller 235 moves to the low position, the support rod 234 moves downward. At this time, the first guide rod 236 and the second guide rod 237 both rotate relative to the support rod 234, and the included angle between them becomes smaller. At the same time, under the pulling action of the elastic fastener 238, the first clamping member 231 and the second clamping member 232 move closer to each other on the slide rail of the connecting seat 233, thereby clamping the battery.

[0089] When the first roller 235 gradually moves to the high position of the inner boss 131, the support rod 234 moves upward, the first guide rod 236 and the second guide rod 237 both rotate relative to the support rod 234, and the included angle between them increases. At the same time, the elastic fastener 238 is stretched, and the first clamping member 231 and the second clamping member 232 move away from each other on the slide rail of the connecting seat 233, thereby releasing the battery.

[0090] Therefore, the above structure enables the clamping component 230 to clamp and release the battery, effectively ensuring the stability of the battery when the cover is closed.

[0091] Optionally, in order to guide the movement of the clamping assembly 230, the base 210 is provided with a guide rail extending in the vertical direction on the side near the support rod 234, and the support rod 234 is slidably connected to the guide rail.

[0092] In this embodiment, when the rotating mechanism 110 rotates, the lifting assembly 240 can move up and down in the vertical direction under the guidance of the outer boss 132, thereby lifting the battery.

[0093] To achieve the above functions, in a specific embodiment, such as Figure 3 As shown, the lifting assembly 240 includes: a lifting rod 241, a support platform 242, and a second roller 243.

[0094] The support platform 242 is connected to the top of the lifting rod 241 and is used to support the battery. The second roller 243 is connected to the bottom of the lifting rod 241 and is used to abut against the outer protrusion 132.

[0095] In this embodiment, such as Figure 4 As shown, the battery can be placed on the support plate 251. To facilitate the lifting assembly 240 in supporting the battery, the support plate 251 is provided with a through hole running vertically through it, and the support platform 242 is placed in the through hole. Optionally, the top of the support platform 242 does not extend beyond the top surface of the support plate 251.

[0096] In practical applications, after the battery is placed on the support plate 251, when it is necessary to lift the battery using the lifting assembly 240, the second roller 243 at the bottom of the lifting rod 241 can move on the outer protrusion 132. When the second roller 243 gradually moves to the high position of the outer protrusion 132, the lifting rod 241 moves upward, and the support platform 242 can lift the battery to the highest position.

[0097] When the battery needs to be lowered using the lifting assembly 240, the second roller 243 gradually moves to the low position of the outer protrusion 132, the lifting rod 241 moves downward, and the support platform 242 can lower the battery onto the support plate 251.

[0098] Therefore, the above structure enables the lifting component 240 to lift and lower the battery, effectively ensuring the stability of the battery when the cover is closed.

[0099] 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.

[0100] In this embodiment, as follows: Figure 4As shown, the lifting rod 241 includes an upper support rod 2411, an inner sleeve rod 2412, and a lower support rod 2413. The bottom end of the upper support rod 2411 is connected to the top end of the lower support rod 2413, and the bottom end of the lower support rod 2413 is connected to the second roller 243. The upper support rod 2411 has a hollow tubular structure with a buffer spring 2414 installed inside its cavity. The inner sleeve rod 2412 is inserted into the cavity of the upper support rod 2411, and its top end is connected to the support platform 242. The two ends of the buffer spring 2414 abut against the bottom end of the inner sleeve rod 2412 and the top end of the lower support rod 2413, respectively.

[0101] Therefore, by setting the buffer spring 2414, when the lifting assembly 240 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.

[0102] Optionally, to facilitate adjustment of the length of the entire lifting assembly 240, the upper support rod 2411 is provided with a threaded hole, and the inner sleeve rod 2412 is provided with a limiting groove extending along its axial direction. The bolt can be threaded to the threaded hole of the upper support rod 2411 and abut against the limiting groove of the inner sleeve rod 2412. The bolt can effectively limit the relative position between the upper support rod 2411 and the inner sleeve rod 2412.

[0103] Therefore, by adjusting the relative position between the upper support rod 2411 and the inner sleeve rod 2412, and by fixing the upper support rod 2411 and the inner sleeve rod 2412 with bolts, the length of the entire lifting assembly 240 can be easily adjusted.

[0104] Furthermore, according to embodiments of the present invention, a method for closing the cover of a turret-type cylindrical battery cover as described in the above embodiments is also provided, such as... Figure 5 As shown, the method of closing the lid includes:

[0105] S1: Controls the turret rotation;

[0106] S2: Control the battery feeding device to transport the battery to the turret and make the lifting component carry the battery; control the cover plate feeding device to transport the cover plate to the turret and make the pressing component obtain the cover plate.

[0107] S3: The pressing component moves downward, the clamping component gradually clamps the battery, and aligns the position of the battery with the position of the cover plate. The lifting component lifts the battery upward.

[0108] S4: The pressing assembly presses the cover plate onto the top of the battery and secures the cover plate to the top of the battery.

[0109] It is understood that in this capping method, the turret-type cylindrical battery capping device can be used in conjunction with the battery feeding device and the cap feeding device. The battery feeding device can transport the battery to the turret, and the cap feeding device can transport the cap to the turret.

[0110] Specifically, in the cap-closing method of this embodiment, the turret's rotating mechanism is first controlled to rotate. Then, the battery feeding device is controlled to transport the battery to the turret, allowing it to be supported by the lifting assembly. The cap feeding device is controlled to transport the cap to the turret, allowing the pressing assembly to obtain the cap. Subsequently, as the rotating mechanism rotates, the pressing assembly moves downwards under the guidance of the upper boss, and the clamping assembly, guided by the inner boss, gradually clamps the battery, aligning its position with the cap. The lifting assembly, guided by the outer boss, lifts the battery upwards. Finally, the pressing assembly presses the cap onto the top of the battery, securing it in place.

[0111] Therefore, the turret-type cylindrical battery cover device in this embodiment has the following advantages:

[0112] The turret-type cylindrical battery capping device in this embodiment includes a turret and a capping mechanism. The turret includes a rotating mechanism, an upper turntable, and a lower turntable. The capping mechanism includes a base, a pressing component, a clamping component, and a lifting component. The pressing component abuts against the upper boss of the upper turntable, while the clamping and lifting components abut against the inner and outer bosses of the lower turntable, respectively. When the cap and battery are transferred to the turret, the clamping component clamps the battery, the pressing component picks up the cap, and the lifting component lifts the battery, allowing the cap to be accurately pressed onto the top of the battery. This ensures the accuracy of the press-fit between the cap and the battery. Furthermore, as the rotating mechanism rotates, the capping mechanism continuously presses the cap onto the top of the battery, ensuring pressing efficiency and improving battery production efficiency. Simultaneously, the capping mechanism occupies relatively little space around the turret, facilitating the setup of the entire battery production line.
