Description

Cap pressing mechanism and battery production equipment

[0001] This patent application claims priority to Chinese Patent Application No. 202423080278.2, filed on December 12, 2024, entitled "Cap Pressing Mechanism and Battery Production Equipment", which is incorporated herein by reference in its entirety. Technical Field

[0002] This invention relates to the field of battery production equipment technology, and more specifically, to a cap pressing mechanism and battery production equipment. Background Technology

[0003] In related technologies, during the manufacturing process of cylindrical batteries, after the cap and the cell inside the casing are connected via tabs, the cap located on the upper side of the casing needs to be pressed into the casing. During processing and transportation, the battery is generally placed in a tray with a through-hole at the bottom. The battery is secured in the tray by the friction between the battery's sidewall and the inner wall of the tray. Currently, the tray containing the battery is typically placed on a support plate, and then the cap is pressed into the casing using a pressing rod. During this pressing process, the battery moves downwards relative to the tray under the downward pressure, causing the bottom surface of the battery casing to come into contact with the support plate. Therefore, when the tray containing the battery is removed after the cap is in place, there is significant friction between the bottom surface of the battery casing and the support plate, which can easily scratch the bottom surface of the battery casing.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] One object of the present invention is to provide a new technical solution for a cap pressing mechanism.

[0033] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0035] This application provides a cap pressing mechanism. As shown in Figures 1 to 5, the cap pressing mechanism includes a support assembly 1 and a pressing assembly 2. The support assembly 1 includes a first support member 11 and a second support member 12. The first support member 11 is adapted to support a cup 7, and the second support member 12 is slidable relative to the first support member 11, thereby extending into the cup 7 to support the battery within the cup 7. The second support member 12 is also slidable relative to the first support member 11 to detach from the cup 7. The pressing assembly 2 is located on one side of the support assembly 1 and is adapted to press the battery cap 53 into the battery casing 51.

[0036] In some embodiments, as shown in Figures 3 and 4, the battery is fixedly disposed within the cup 7. The first support member 11 supports the cup 7 containing the battery; for example, the cup 7 can be placed on the support surface of the first support member 11. The second support member 12 can slide relative to the first support member 11, thereby extending into the cup 7 to support the battery within it. Specifically, the bottom end of the cup 7 has a through hole, through which the second support member 12 can extend into the cup 7 and support the end of the battery casing 51 facing away from the cap 53. After the cap 53 is pressed in, the second support member 12 can also slide relative to the first support member 11 to slide out of the cup 7, thereby reducing friction on the battery and preventing scratches on the bottom surface of the battery casing 51.

[0037] As shown in Figure 2, in some embodiments, the cap 53 is connected to the battery cell inside the battery housing 51 via a tab 52, and the cap 53 located on the upper side of the housing is pressed into the housing by a cap pressing mechanism.

[0038] In some embodiments, the pressing component 2 is located on one side of the support component 1. The first support member 11 can be a support plate, and a support surface is provided at one end of the first support member 11 facing the pressing component 2, on which the cup 7 can be fixedly placed. The second support member 12 can slide relative to the first support member 11 toward the battery housing 51 to protrude from the support surface. For example, the second support member 12 can protrude about 1 mm from the support surface and can extend into the cup 7 from the lower end of the cup 7, thereby supporting the bottom surface of the battery housing 51 inside the cup 7. During the pressing of the cap 53, the second support member 12 can support the battery housing 51 to prevent the battery housing 51 from moving downward and abutting against the support surface. When the cap 53 is pressed into the battery housing 51, the second support member 12 can slide away from the battery housing 51 relative to the first support member 11 and slide out of the cup 7. For example, the second support member 12 can be retracted into the first support member 11 by about 1 mm, so that the bottom surface of the battery housing 51 will not be rubbed when the battery is transferred, so as to avoid scratching the bottom surface of the battery housing 51.

[0039] In one example, as shown in Figures 2 to 5, the first support member 11 is provided with a clearance hole 111, and the second support member 12 can pass through the clearance hole 111.

[0040] As shown in Figures 2 to 5, the first support member 11 has a through-hole 111. The second support member 12 can be a support rod structure. One end of the second support member 12 can pass through the through-hole 111 and be inserted into the first support member 11 to support the battery housing 51. The other end of the second support member 12 can also be embedded in the through-hole 111. The second support member 12 can slide along the through-hole 111, and the through-hole 111 guides and limits the second support member 12 to prevent it from shifting.

[0041] In one example, as shown in FIG1, the support assembly 1 further includes a first mounting member 13, wherein the first support member 11 and the second support member 12 are slidably connected to the first mounting member 13, and the first support member 11 is movable toward or away from the pressing assembly 2.

[0042] As shown in Figure 1, in some embodiments, the first support member 11 is slidably mounted on the first mounting member 13 along a first direction, and the pressing component 2 is located on one side of the first support member 11 along the first direction. The first support member 11 can slide away from the pressing component 2 along the first direction, thereby increasing the space between the first support member 11 and the pressing component 2 to facilitate the loading operation. After the cup 7 is placed on the first support member 11, the first support member 11 can also move towards the pressing component 2 to cooperate with the pressing component 2 to press the cap 53 into the battery housing 51. The second support member 12 is slidably disposed on the first mounting member 13 and can slide towards or away from the battery housing 51 relative to the first support member 11.

[0043] As shown in Figure 1, in some embodiments, the first mounting member 13 is provided with a first slide rail 132 along a first direction, and the first support member 11 can be connected to the first slide rail 132 by a second connector 16. For example, the second connector 16 can be a slider, and the first support member 11 can be fixedly connected to the second connector 16 by fasteners such as screws or bolts.

[0044] In one example, as shown in Figure 1, the support assembly 1 further includes a first connector 14, a second support 12 mounted on the first connector 14, a first support 11 being tractively connected to the first connector 14, and the first connector 14 being able to drive the first support 11 and the second support 12 to move.

[0045] As shown in Figure 1, in some embodiments, the first connecting member 14 can be a slider, and one end of the second support member 12 can be screwed to the first connecting member 14. The second support member 12 can be slidably connected to the first slide rail 132 through the first connecting member 14. The first connecting member 14 is also a transmission connector with the first support member 11, and the first connecting member 14 can also drive the first support member 11 to move along a first direction. That is, the first connecting member 14 can slide along the first slide rail 132, thereby driving the first support member 11 and the second support member 12 to slide along the first direction.

[0046] As shown in Figures 2 to 4, in some embodiments, the first mounting member 13 is provided with a limiting part 131, which can restrict the movement of the first support member 11 so that the first connecting member 14 can drive the second support member 12 to move relative to the first support member 11.

[0047] As shown in Figures 2 and 3, when the cap 53 is pressed down, the first connecting member 14 can first drive the first support member 11 and the second support member 12 to move synchronously toward the pressing assembly 2. As shown in Figure 4, after the first connecting member 14 drives the first support member 11 and the second support member 12 to move to the preset position, the first support member 11 can abut against the limiting part 131 on the first mounting member 13. For example, the limiting part 131 can be a limiting block integrally formed on the first mounting member 13. The first support member 11 can abut against the lower end of the limiting block, thereby restricting the first support member 11 from continuing to move, so that the first connecting member 14 can drive the second support member 12 to move relative to the first support member 11, so as to protrude from the first support member 11 and extend into the cup 7.

[0048] In one example, as shown in FIG1, the support component 1 further includes an elastic element 15, one end of which abuts against the first connector 14 and the other end of which abuts against the first support element 11.

[0049] As shown in Figure 1, in some embodiments, an elastic element 15 is provided between the first connector 14 and the first support 11. The elastic element 15 can be a compression spring, with one end abutting against the first connector 14 and the other end abutting against the first support 11. Alternatively, the end of the elastic element 15 away from the first connector 14 can also abut against the second connector 16.

[0050] When the cap 53 is pressed down, the first connecting member 14 moves along the first slide rail 132 toward the pressing assembly 2, thereby driving the second support member 12 to move. Furthermore, the first connecting member 14 can push the first support member 11 to move via the elastic member 15. After the first connecting member 14 drives the first support member 11 and the second support member 12 to a preset position, the first support member 11 abuts against the limiting portion 131 on the first mounting member 13, thereby restricting further movement of the first support member 11. At this time, the first connecting member 14 continues to move toward the pressing assembly 2, and the elastic member 15 compresses, thereby driving the second support member 12 to move relative to the first support member 11, protruding from the first support member 11 and extending into the cup 7.

[0051] After the cap 53 is pressed into the battery housing 51, the first connector 14 moves away from the pressing component 2 along the first slide rail 132, thereby driving the second support 12 to move down first, and through the elastic member 15, the end of the second support 12 used to support the battery housing 51 can be pushed to be embedded in the first support 11.

[0052] In one example, one end of the second support member 12 can be inserted through the first support member 11, and the elastic member 15 is sleeved on the second support member 12.

[0053] In some embodiments, the second support member 12 can be a support rod structure, with one end connected to the first connector 14 and the other end passing through the second connector 16 and the first support member 11 in sequence. An elastic member 15 is sleeved on the second support member 12, with one end abutting against the first connector 14 and the other end abutting against the second connector 16. Sleeving the elastic member 15 on the second support member 12 can position the elastic member 15 without requiring additional positioning components.

[0054] In one example, as shown in Figures 1 to 4, the pressing assembly 2 further includes a pressing member 21 movably disposed along a first direction. The pressing member 21 is movable toward the first support member 11 and is capable of pressing the cap 53 into the battery housing 51.

[0055] As shown in Figures 1 to 4, in some embodiments, the pressing assembly 2 is provided with a pressing member 21 for pressing the cap 53 into the battery housing 51. The pressing member 21 is slidably disposed along a first direction. That is, after the battery housing 51 is placed on the first support member 11, the pressing member 21 can move toward the cap 53. For example, the pressing member 21 can be a pressing rod, one end of which can abut against one end of the cap 53 to press the cap 53 into the battery housing 51. The pressing member 21 can move away from the first support member 11, thereby increasing the distance between the first support member 11 and the pressing member 21, which is beneficial for loading.

[0056] In one example, as shown in Figures 1 and 5, the cap pressing mechanism further includes a drive assembly that drives the pressing member 21 to move via a cam drive. The drive assembly includes a cam structure 34 and a first follower 31. The first follower 31 is connected to the pressing member 21 and can move circumferentially along the cam structure 34 to drive the pressing member 21 toward the first support member 11. A first detection member is disposed on the cam structure 34 to detect the distance the first follower 31 moves in a first direction.

[0057] As shown in Figures 1 and 5, in some embodiments, the driving assembly can drive the pressing member 21 to move via a cam transmission. Specifically, a first follower 31, which can be a cylindrical wheel, is connected to the pressing member 21. The cam structure 34 is provided with a first guide rail 341, which can be annular or curved. The first follower 31 rolls along the first guide rail 341, driving the pressing member 21 to move in a first direction, thereby moving the pressing member 21 toward or away from the first support member 11. The driving assembly may also include a rotating shaft, which drives the pressing assembly 21 to rotate circumferentially along the cam structure 34, thereby driving the first follower 31 to roll on the first guide rail 341.

[0058] In some embodiments, the cap pressing mechanism further includes a first detection element, which is adapted to detect the distance the pressing member 21 moves in a first direction. The first direction can be a vertical direction. When pressing down the cap 53, the pressing member 21 can move downwards by a preset distance to press the cap 53 into the battery casing 51. The first detection element can detect the downward movement distance of the pressing member 21 to ensure that the pressing member 21 can move downwards by a preset distance. If the downward movement distance of the pressing member 21 is insufficient, it indicates that the cap 53 has not been fully pressed in, and the first detection element can issue an alarm signal. By setting the first detection element, the pressing effect of the cap 53 is ensured.

[0059] In some embodiments, the first detection element is disposed on the cam structure 34 to detect the distance the first follower 31 moves in a first direction. The first guide rail 341 of the cam structure 34 has a downward section, that is, the first follower 31 can roll along the downward section, thereby driving the pressing member 21 to move downward. The first detection element can be disposed on the upper side of the downward section. When the first follower 31 does not contact the surface of the downward section of the first guide rail 341, the first follower 31 will be opposite to the first detection element, thereby detecting that the first follower 31 has not descended to the preset position.

[0060] The first detection element may include a cylinder. When the first follower 31 has not descended to the preset position, the first follower 31 can abut against the output end of the cylinder, and the position of the first follower 31 can be detected by the force applied to the cylinder. Alternatively, the first detection element may also be a position sensor or other structure. Those skilled in the art can determine the appropriate element based on the actual situation, and no specific limitation is made here.

[0061] In one example, as shown in Figures 1 to 4, the pressing assembly 2 further includes a clamping member 22, which can be opened or clamped. One end of the battery having a cap 53 can be inserted into the opened clamping member 22, and the clamping member 22 can also clamp and position the cap 53.

[0062] In some embodiments, when the cup 7 is placed on the first support 11, the clamping member 22 is in an open state and can move toward the first support 11 so that one end of the battery with the cap 53 can be inserted into the open clamping member 22. Then the clamping member 22 can also clamp to position the cap 53 so that when the pressing member 21 presses the cap 53 into the battery housing 51, the cap 53 can be coaxial with the battery housing 51.

[0063] As shown in Figure 2, the clamping member 22 includes a mold-closing sleeve 221 and a three-lobed claw 222. The three claws of the three-lobed claw 222 can move away from each other, so that the three-lobed claw 222 is in an open rotating state. As shown in Figure 3, the battery casing 51 is inserted into the open three-lobed claw 222. The mold-closing sleeve 221 can move toward the three-lobed claw 222 and fit over the outside of the three-lobed claw 222. The mold-closing sleeve 221 can push the multiple claws closer to each other, so that the three-lobed claw 222 is in a clamping state to position the cap 53. The pressing member 21 is partially slidably disposed inside the mold-closing sleeve 221. After the cap 53 is pressed in, the mold-closing sleeve 221 can move to disengage from the three-lobed claw 222. The three claws of the three-lobed claw 222 can move away from each other by the action of springs to open the three-lobed claw 222.

[0064] In some embodiments, the clamping member 22 is further provided with a second follower 32, which can be a cylindrical wheel. The cam structure 34 is also provided with a second guide rail 342. The second guide rail 342 is arranged in a ring and can be located above the first guide rail 341. The structure of the second guide rail 342 is similar to that of the first guide rail 341. The second follower 32 can roll along the second guide rail 342, thereby driving the clamping member 22 to move in the first direction. The cap pressing mechanism also includes a second detection member, which can detect the movement distance of the clamping member 22 in the first direction. The structure and detection process of the second detection member and the first detection member can be the same.

[0065] In one example, the first connecting member 14 is further provided with a third follower 33, which can be a cylindrical wheel. The cam structure 34 is further provided with a third guide rail, along which the third follower 33 can roll, thereby driving the first connecting member 14 to move in a first direction. For example, the first mounting member 13 can be driven to a rotating shaft, which can drive the first mounting member 13 to rotate circumferentially along the cam structure 34, thereby driving the third follower 33 to roll along the surface of the third guide rail.

[0066] In one example, as shown in Figure 1, the cap pressing mechanism further includes a second mounting member 4, the pressing component 2 being slidably connected to the second mounting member 4, the pressing component 2 being provided with a suspension part 23, the suspension part 23 being able to be suspended from the second mounting member 4.

[0067] As shown in Figure 1, the second mounting member 4 is provided with a stop, and the pressing component 2 is also provided with a suspension part 23. For example, the suspension part 23 can be a hook provided on the pressing component 2, which can be hooked on the stop to restrict the sliding of the pressing component 2. For example, when the pressing component 2 needs to be repaired, the suspension part 23 can be hung on the second mounting member 4 first, and then the second mounting member 4 can be removed, which can prevent the pressing component 2 from sliding on the second mounting member 4 and causing collisions or other problems.

[0068] As shown in Figure 1, a second slide rail 41 is provided on the second mounting component 4 along the first direction, and the pressing component 2 can be slidably connected to the second slide rail 41. Among them, the pressing component 21 can be slidably connected to the second slide rail 41, and the clamping component 22 can be slidably connected to the second slide rail 41.

[0069] This application also provides a battery production apparatus. The battery production apparatus includes the cap pressing mechanism described in the above embodiments. The cap pressing mechanism includes a support assembly 1 and a pressing assembly 2. The support assembly 1 includes a first support member 11 and a second support member 12. The battery is fixedly disposed within a cup 7. The first support member 11 can support the cup 7 containing the battery; for example, the cup 7 can be placed on the support surface of the first support member 11. The second support member 12 can slide relative to the first support member 11, thereby extending into the cup 7 to support the battery within the cup 7. That is, the bottom end of the cup 7 is provided with a through hole, and the second support member 12 can extend into the cup 7 through the through hole and support the end of the battery casing 51 facing away from the cap 53. The pressing assembly 2 can press the cap 53 into the battery casing 51. After the cap 53 is pressed in, the second support member 12 can slide relative to the first support member 11 to slide out of the cup 7, which helps to reduce friction on the bottom surface of the battery housing 51 and avoid scratching the bottom surface of the battery housing 51.

[0070] As shown in Figure 5, in some embodiments, multiple sets of support components 1 and pressing components 2 can be provided. These multiple sets of support components 1 and pressing components 2 are disposed on the base 6 and spaced apart circumferentially along the cam structure 34. A rotating shaft can drive the multiple sets of support components 1 and pressing components 2 to rotate. This allows for the continuous pressing of multiple battery caps 53 into the battery casing 51, improving the pressing efficiency of the caps 53.

[0071] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0072] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention.
