[0035] The present application provides a cap pressing mechanism. As shown in Figures 1 to 5 the cap pressing mechanism includes a supporting assembly 1 and a pressing assembly 2. The supporting assembly 1 includes a first supporting member 11 and a second supporting member 12. The first supporting member 11 is adapted to support a cup 7. The second supporting member 12 is slidable relative to the first supporting member 11, so as to be able to extend into the cup 7 to support a battery in the cup 7. The second supporting member 12 is also slidable relative to the first supporting member 11 to be disengaged from the cup 7. The pressing assembly 2 is located at one side of the supporting assembly 1. The pressing assembly 2 is adapted to press a cap 53 of the battery into a battery housing 51.

[0036] In some embodiments, as shown in Figure 3 and Figure 4 the battery is fixedly arranged in the cup 7. The first supporting member 11 is able to support the cup 7 containing the battery. For example, the cup 7 can be placed on a supporting surface of the first supporting member 11. The second supporting member 12 is slidable relative to the first supporting member 11, so as to be able to extend into the cup 7 to support the battery in the cup 7. That is, the cup 7 is provided with a through hole at a bottom end thereof. The second supporting member 12 is able to extend into the cup 7 from the through hole and support an end of the battery housing 51 which is away from the cap 53. After the cap 53 is pressed in, the second supporting member 12 is also slidable relative to the first supporting member 11 to slide out of the cup 7, so as to be able to reduce the friction on the battery and avoid scratching the bottom surface of the battery housing 51.

[0037] As shown in Figure 2 some embodiments, the cap 53 is connected between the battery cell in the battery shell 51 and the tab 52 through the cap pressing mechanism, and the cap 53 on the upper side of the shell is pressed into the shell.

[0038] In some embodiments, the pressing assembly 2 is located on one side of the support assembly 1. The first support 11 can be a support plate, and one end of the first support 11 is provided with a support surface facing the pressing assembly 2, and the cup 7 can be fixedly placed on the support surface. The second support 12 can slide relative to the first support 11 to protrude from the support surface, for example, the second support 12 can protrude from the support surface by about 1 mm, and can extend into the cup 7 from the lower end of the cup 7, thereby supporting the bottom surface of the battery shell 51 in the cup 7. During the pressing of the cap 53 into the battery shell 51, the second support 12 can support the battery shell 51 to avoid moving downward and abutting against the support surface. After the cap 53 is pressed into the battery shell 51, the second support 12 can slide away from the battery shell 51 relative to the first support 11 and can slide out of the cup 7, for example, the second support 12 can be retracted into the first support 11 by about 1 mm, thereby avoiding friction on the bottom surface of the battery shell 51 during the transportation of the battery to avoid scratching the bottom surface of the battery shell 51.

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

[0040] As shown in Figures 2 to 5 the first support 11 is provided with an avoiding hole 111, and the second support 12 can pass through the avoiding hole 111.

[0041] In one example, as shown in Figure 1 the support assembly 1 further includes a first mounting 13, and the first support 11 and the second support 12 are respectively slidably connected to the first mounting 13, and the first support 11 can move towards or away from the pressing assembly 2.

[0042] As shown in Figure 1As shown, 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] like Figure 1 As shown, 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, such as Figure 1 As shown, the support assembly 1 further includes a first connector 14, a second support 12 is mounted on the first connector 14, and the first support 11 is tractively connected to the first connector 14. The first connector 14 can drive the first support 11 and the second support 12 to move.

[0045] like Figure 1 As shown, 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] like Figures 2 to 4 As shown, 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] like Figure 2 and Figure 3 As shown, when the cap 53 is pressed down, the first connector 14 can first drive the first support 11 and the second support 12 to move synchronously toward the pressing assembly 2. Figure 4As shown, after the first connecting piece 14 drives the first supporting piece 11 and the second supporting piece 12 to move to the preset position, the first supporting piece 11 can abut against the limiting part 131 on the first mounting piece 13, for example, the limiting part 131 can be a limiting block integrally formed on the first mounting piece 13, and the first supporting piece 11 can abut against the lower end of the limiting block, so as to limit the continuous movement of the first supporting piece 11, so that the first connecting piece 14 can drive the second supporting piece 12 to move relative to the first supporting piece 11, so as to protrude from the first supporting piece 11 and extend into the cup 7.

[0048] In one example, as shown in Figure 1 As shown, the supporting assembly 1 further comprises an elastic piece 15, one end of the elastic piece 15 abuts against the first connecting piece 14, and the other end abuts against the first supporting piece 11.

[0049] As shown in Figure 1 In some embodiments, an elastic piece 15 is arranged between the first connecting piece 14 and the first supporting piece 11. The elastic piece 15 can be a compression spring, one end of the elastic piece 15 can abut against the first connecting piece 14, and the other end can abut against the first supporting piece 11, or the end of the elastic piece 15 away from the first connecting piece 14 can abut against the second connecting piece 16.

[0050] When the cap 53 is pressed down, the first connecting piece 14 moves along the first sliding rail 132 towards the pressing-down assembly 2, so as to drive the second supporting piece 12 to move, and the first connecting piece 14 can drive the first supporting piece 11 to move through the elastic piece 15. After the first connecting piece 14 drives the first supporting piece 11 and the second supporting piece 12 to move to the preset position, the first supporting piece 11 can abut against the limiting part 131 on the first mounting piece 13, so as to limit the continuous movement of the first supporting piece 11. At this time, the first connecting piece 14 continues to move towards the pressing-down assembly 2, the elastic piece 15 is compressed, so as to drive the second supporting piece 12 to move relative to the first supporting piece 11, so as to protrude from the first supporting piece 11 and extend into the cup 7.

[0051] After the cap 53 is pressed into the battery shell 51, the first connecting piece 14 moves away from the pressing-down assembly 2 along the first sliding rail 132, so as to first drive the second supporting piece 12 to move downward, and the end of the second supporting piece 12 for supporting the battery shell 51 can be embedded into the first supporting piece 11 through the elastic piece 15.

[0052] In one example, one end of the second supporting piece 12 can pass through the first supporting piece 11, and the elastic piece 15 is sleeved on the second supporting piece 12.

[0053] In some embodiments, the second support 12 can be a support rod structure, one end of the second support 12 is connected to the first connecting piece 14, and the other end can be sequentially arranged in the second connecting piece 16 and the first support 11. The elastic piece 15 is sleeved on the second support 12, one end of the elastic piece 15 abuts against the first connecting piece 14, and the other end abuts against the second connecting piece 16. The elastic piece 15 is sleeved on the second support 12, which can play a positioning role on the elastic piece 15, and there is no need to additionally set a positioning piece to position the elastic piece 15.

[0054] In one example, as shown in Figures 1 to 4 The pressing assembly 2 further comprises a pressing piece 21 movably arranged in the first direction, the pressing piece 21 can move towards the first support 11 and can press the cap 53 into the battery shell 51.

[0055] As shown in Figures 1 to 4 In some embodiments, the pressing assembly 2 is provided with a pressing piece 21 for pressing the cap 53 into the battery shell 51, and the pressing piece 21 is slidably arranged in the first direction. That is, after the battery shell 51 is placed on the first support 11, the pressing piece 21 can move towards the cap 53, for example, the pressing piece 21 can be a pressing rod, one end of the pressing rod can abut against one end of the cap 53 to press the cap 53 into the battery shell 51. The pressing piece 21 can move away from the first support 11, so as to increase the distance between the first support 11 and the pressing piece 21, thereby facilitating feeding.

[0056] In one example, as shown in Figure 1 and Figure 5 The cap pressing mechanism further comprises a driving assembly, the driving assembly drives the pressing piece 21 to move through cam transmission, the driving assembly comprises a cam structure 34 and a first follower 31, the first follower 31 is connected to the pressing piece 21, the first follower 31 can move along the circumference of the cam structure 34 to drive the pressing piece 21 to move towards the first support 11, and the first detection piece is arranged on the cam structure 34 to detect the distance of the first follower 31 moving in the first direction.

[0057] As shown in Figure 1 and Figure 5As shown, in some embodiments, the driving assembly can drive the pressing member 21 to move through cam transmission. That is, the pressing member 21 is connected with a first follower 31, which can be a cylindrical wheel. The cam structure 34 is provided with a first guide rail 341, which can be annularly arranged. The first guide rail 341 is arranged in a curve shape. The first follower 31 rolls along the first guide rail 341 and can drive the pressing member 21 to move in a first direction, so as to drive the pressing member 21 to move towards or away from the first support 11. The driving assembly can further include a rotating shaft. The rotating shaft can drive the pressing assembly 2 to rotate along the circumference of the cam structure 34, so as to drive 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 member adapted to detect the distance of the pressing member 21 moving in the first direction. The first direction can be a vertical direction. When the cap 53 is pressed, the pressing member 21 can move downward by a preset distance to press the cap 53 into the battery shell 51. The first detection member can detect the distance of the pressing member 21 moving downward, so as to ensure that the pressing member 21 can move downward by a preset distance. When the distance of the pressing member 21 moving downward is insufficient, it indicates that the cap 53 is not completely pressed in. The first detection member can send an alarm signal. By arranging the first detection member, the pressing effect of the cap 53 can be ensured.

[0059] In some embodiments, the first detection member is arranged on the cam structure 34 to detect the distance of the first follower 31 moving in the 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 to drive the pressing member 21 to move downward. The first detection member can be arranged on the upper side of the downward section. When the first follower 31 is not in contact with the surface of the downward section of the first guide rail 341, the first follower 31 will be opposite to the first detection member, so as to detect that the first follower 31 does not move downward to a preset position.

[0060] The first detection member can include a gas cylinder. When the first follower 31 does not move downward to a preset position, the first follower 31 can abut against the output end of the gas cylinder. The position of the first follower 31 can be detected through the force of the gas cylinder. Alternatively, the first detection member can also be a position sensor or the like. The skilled in the art can determine according to the actual situation, which is not limited here.

[0061] In one example, as shown in the drawings, 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 with the cap 53 can be inserted into the opened clamping member 22. 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 holding member 22 is in an open state, and the holding member 22 can move towards the first support 11, so that one end of the battery with the cap 53 can be inserted into the open holding member 22. Then the holding member 22 can also be clamped, so as to position the cap 53, so that the pressing member 21 can make the cap 53 coaxial with the battery shell 51 when pressing the cap 53 into the battery shell 51.

[0063] As shown in Figure 2 , the holding member 22 includes a mold closing sleeve 221 and a three-petal claw 222, and the three clamping claws of the three-petal claw 222 can move away from each other to make the three-petal claw 222 in an open state. As shown in Figure 3 , the battery shell 51 is inserted into the open three-petal claw 222, the mold closing sleeve 221 can move towards the three-petal claw 222 and be sleeved outside the three-petal claw 222, and the mold closing sleeve 221 can push the multiple clamping claws to move close to each other, so as to make the three-petal claw 222 in a clamped state to position the cap 53, and the pressing member 21 is partially arranged in the mold closing sleeve 221. After the cap 53 is pressed in, the mold closing sleeve 221 can be moved to be separated from the three-petal claw 222, and the three clamping claws of the three-petal claw 222 can move away from each other to open the three-petal claw 222 under the action of the spring.

[0064] In some embodiments, the holding member 22 is further provided with a second follower 32, which can be a cylindrical wheel. The cam structure 34 is further provided with a second guide rail 342. The second guide rail 342 is annularly arranged, and the second guide rail 342 can be located above the first guide rail 341, and 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, so as to drive the holding member 22 to move in the first direction. The cap pressing mechanism further includes a second detection member, which can detect the movement distance of the holding 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, and the third follower 33 can roll along the third guide rail, so as to drive the first connecting member 14 to move in the first direction. For example, the first mounting member 13 can be in transmission connection with a rotating shaft, and the rotating shaft can drive the first mounting member 13 to rotate along the circumference of the cam structure 34, so as to drive the third follower 33 to roll along the surface of the third guide rail.

[0066] In one example, as shown in Figure 1As shown, the cap pressing mechanism further comprises a second mounting member 4, the pressing assembly 2 is slidingly connected to the second mounting member 4, and the pressing assembly 2 is provided with a hanging part 23 which can be hung on the second mounting member 4.

[0067] As shown, Figure 1 The second mounting member 4 is provided with a stop part, and the pressing assembly 2 is also provided with a hanging part 23, for example, the hanging part 23 can be a hook provided on the pressing assembly 2, and the hook can be hung on the stop part, so as to limit the sliding of the pressing assembly 2. For example, when the pressing assembly 2 needs to be maintained, the hanging part 23 can be hung on the second mounting member 4 first, and then the second mounting member 4 can be disassembled, so as to avoid the collision of the pressing assembly 2 on the second mounting member 4 and other problems.

[0068] As shown, Figure 1 The second mounting member 4 is provided with a second sliding rail 41 along the first direction, and the pressing assembly 2 can be slidingly connected to the second sliding rail 41. Among them, the pressing part 21 can be slidingly connected to the second sliding rail 41, and the clamping part 22 can be slidingly connected to the second sliding rail 41.
