Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and more specifically, to a steel shell ejection device. Background Technology

[0002] A battery typically consists of a core and a steel casing. The core is housed within the steel casing, which protects it from deformation caused by external impacts. During battery manufacturing, the steel casing and core are manufactured separately. After production, the core is inserted into the casing. To facilitate transport, the manufactured steel casing is typically placed in a support cup. Before the core is inserted into the casing, a battery casing-support cup separation mechanism removes the steel casing from the support cup, separating it for subsequent core insertion.

[0003] Existing steel shell ejection devices typically use a lifting assembly to lift the steel shell out of the holder. However, during the lifting process, the steel shell continuously rubs against the steel shell fixture and the holder, causing external wear on the steel shell. This can easily lead to inconsistencies in the appearance of the steel shell and affect the quality of the battery. Utility Model Content

[0004] The present invention aims to solve the problem that existing steel shell ejection devices easily cause external wear on the steel shell during separation, resulting in inconsistent appearance of the steel shell.

[0005] To solve the above problems, this utility model provides a steel shell ejection device, comprising:

[0006] A rotating assembly includes a turntable and a rotating shaft, wherein the turntable is capable of rotating about the rotating shaft as a center of rotation;

[0007] A cup-holding fixture, wherein multiple cup-holding fixtures are evenly distributed along the circumference of the turntable, and the cup-holding fixtures are used to fix the cups;

[0009] The cup holder assembly is connected to the cup holder fixture in a one-to-one correspondence. The cup holder assembly is used to drive the cup holder fixture to move in the vertical direction and adjust the distance between the cup holder fixture and the steel shell fixture in the vertical direction so that the cup holder and the steel shell are separated.

[0010] Furthermore, the turntable includes a first turntable and a second turntable, the second turntable is arranged around the outer periphery of the first turntable, the first turntable is evenly provided with a plurality of first grooves along its circumference, and the second turntable is evenly provided with a plurality of second grooves along its circumference, the second grooves and the first grooves being arranged correspondingly.

[0011] Furthermore, the cup holder includes a slot and a support plate. The slot is accommodated in the first groove and is used to hold the side wall of the cup. The support plate is accommodated in the second groove and is in contact with the bottom of the cup. The support plate is used to support the cup.

[0012] Furthermore, the steel shell fixture is mounted on the first turntable.

[0013] Furthermore, it also includes a guide cam, which is disposed below the second turntable, is coaxial with the turntable, and has a guide ramp around its periphery.

[0014] Furthermore, the cup-feeding assembly includes a cam follower, which is disposed on the guide ramp and moves along the guide ramp during the rotation of the cup-feeding fixture around the rotating shaft, thereby driving the cup-feeding fixture to reciprocate in the vertical direction.

[0015] Furthermore, the cup-feeding assembly also includes a guide frame and a mounting plate. The guide frame passes through the first turntable, the cam follower is disposed at the second end of the guide frame, the mounting plate is disposed on the guide frame, and the mounting plate is located between the first end and the second end of the guide frame. The cup-feeding fixture is mounted on the mounting plate, and the first end and the second end are the two ends of the guide frame that are arranged opposite each other in the vertical direction.

[0016] Furthermore, the guide frame includes guide rods, a first connecting block, and a second connecting block. The two guide rods are vertically mounted on the first turntable. The first connecting block connects the two guide rods to the first end of the guide frame, and the second connecting block connects the two guide rods to the second end of the guide frame. The cam follower is connected to the second connecting block.

[0017] Furthermore, the steel shell fixture is provided with a magnetic suction element on the side facing the steel shell placement position, and the magnetic suction element is used to attract the side wall of the steel shell.

[0018] Furthermore, it also includes a driving component connected to the rotating shaft, the driving component being used to drive the rotating shaft to rotate.

[0019] The steel shell ejection device of this utility model drives the cup holder fixture to move vertically through the ejection assembly, adjusting the vertical distance between the cup holder fixture and the steel shell fixture. When the vertical distance between the cup holder fixture and the steel shell fixture is large, the distance between the cup holder and the steel shell can be increased, thereby achieving separation of the cup holder and the steel shell. By driving the cup holder fixture to move vertically, the steel shell and the steel shell fixture can be kept relatively stationary during steel shell ejection, avoiding friction of the steel shell in the steel shell fixture and reducing the risk of friction deformation of the steel shell. In addition, the ejection assembly is connected to the cup holder fixture, and both the cup holder fixture and the steel shell fixture are mounted on the same turntable, which can ensure the positional tolerance between the steel shell fixture and the cup holder fixture, which is conducive to further reducing frictional damage between the steel shell and the cup holder, thereby further improving the quality of the battery cell.

[0026] Combination Figures 1 to 3 As shown, this embodiment provides a steel shell ejection device, including: a rotating assembly, a cup holder 30, a steel shell holder 40, and an ejection assembly 50, wherein:

[0027] The rotating assembly includes a turntable 10 and a rotating shaft 20. The turntable 10 can rotate around the rotating shaft 20 as the rotation center. Multiple cup holders 30 are evenly distributed around the circumference of the turntable 10. When the turntable 10 rotates, it drives the cup holders 30 to rotate around the rotating shaft 20. The cup holders 30 are used to fix the cup 1. Multiple steel shell holders 40 are evenly arranged around the circumference of the turntable 10. Each steel shell holder 40 is positioned above the cup holder 30. The steel shell holder 40 is used to clamp the steel shell 2. The number of ejector components 50 is the same as the number of cup holders 30. The ejector components 50 and the cup holders 30 are connected in a one-to-one correspondence. The ejector components 50 are used to drive the cup holders 30 to move in the vertical direction and adjust the vertical distance between the cup holders 30 and the steel shell holders 40 so that the cup 1 and the steel shell 2 are separated.

[0028] The steel shell ejection device provided in this embodiment drives the cup holder fixture to move vertically through the ejection assembly. Adjusting the vertical distance between the cup holder fixture and the steel shell fixture allows for greater vertical separation, increasing the gap between the cup holder and the steel shell. By driving the cup holder fixture vertically, the steel shell and the steel shell fixture remain relatively stationary during ejection, preventing friction within the fixture and reducing the risk of deformation. Furthermore, the ejection assembly is connected to the cup holder fixture, and both fixtures are mounted on the same turntable, ensuring positional tolerances and further reducing frictional damage between the steel shell and the cup holder, thus improving the quality of the battery cell.

[0029] Based on the above embodiments, as an optional implementation, the turntable 10 includes a first turntable 11 and a second turntable 12 coaxially arranged. The second turntable 12 is arranged around the outer periphery of the first turntable 11. The cup holder 30 includes a slot 31 and a support plate 32. The slot 31 and the support plate 32 are connected. The first turntable 11 is evenly provided with a plurality of first grooves along its circumference. Each slot 31 can be accommodated in the first groove. The second turntable 12 is evenly provided with a plurality of second grooves along its circumference. The second grooves are corresponding to the first grooves. Each support plate 32 can be accommodated in the second groove. The slot 31 is used to hold the side wall of the cup holder 1. The support plate 32 contacts the bottom of the cup holder 1 and is used to support the cup holder 1. Therefore, the slot 31 and the support plate 32 can support the cup 1 and limit the position of the cup 1. When the first turntable 11 and the second turntable 12 rotate, the cup 1 can be rotated more smoothly. Furthermore, by setting a first groove on the first turntable 11 and a second groove on the second turntable 12, the cup holder 30 can be moved in the vertical direction, thereby driving the cup 1 to move in the vertical direction.

[0030] Based on the above embodiments, as an optional implementation, both the cup holder 1 and the battery cell are cylindrical, and the slot 31 is arc-shaped, with a radius greater than or equal to the radius of the cup holder 1. Of course, the cup holder 1 and the battery cell can also be rectangular or other shapes, and the slot 31 can also be a rectangle or other shapes corresponding to the cup holder 1 and the battery cell. The shape of the first groove can match the shape of the slot 31, and the shape of the second groove can match the shape of the support plate 32.

[0031] Based on the above embodiments, as an optional implementation, the steel shell fixture 40 is disposed on the first turntable 11, and vertically, the steel shell fixture 40 is positioned above the slot 31. Therefore, by disposing of both the steel shell fixture 40 and the slot 31 on the first turntable 11, it is beneficial to further ensure the positional tolerance between the steel shell fixture and the cup holder fixture.

[0032] Based on the above embodiments, as an optional implementation, the steel shell ejection device further includes a guide cam 60. The guide cam 60 is mounted on a mounting base, which is sleeved outside the rotating shaft 10. When the rotating shaft 10 rotates, the mounting base and the guide cam 60 do not rotate with the rotating shaft 10. The guide cam 60 is located below the second turntable 12 and is coaxial with the turntable 10. A guide ramp 61 is provided around the periphery of the guide cam 60. The ejection assembly 50 includes a cam follower 51, which is located on the guide ramp 61. During the rotation of the cup holder 30 around the rotating shaft 20, the cam follower 51 moves along the guide ramp 61, driving the cup holder 30 to reciprocate in the vertical direction. Therefore, by setting the guide ramp 61 and the cam follower 51, when the cup holder 30 rotates around the rotating shaft 20, the cam follower 51 can rotate along the guide ramp 61, enabling the cam follower 51 to rise and fall periodically, thus realizing the periodic rise and fall of the cup holder 30. In this way, during the process of conveying the cup holder 30, the cup holder 30 can also drive the cup holder 1 to move in the vertical direction, adjusting the vertical distance between the cup holder 30 and the steel shell fixture 40, thereby adjusting the vertical distance between the cup holder 1 and the steel shell 2, and ensuring the consistency of the vertical movement of all cup holders 1, improving the accuracy of the cup holder 1's repeatability.

[0033] Based on the above embodiments, as an optional implementation, the guide ramp 61 includes a first ramp segment and a second ramp segment, which are smoothly connected. The guide ramp 61 has a lowest position and a highest position, which are located at different heights. The first ramp segment is located at the lowest position of the guide ramp 61, and the second ramp segment is located at the highest position of the guide ramp 61. When the cam follower 51 rolls from the second ramp segment to the first ramp segment, the cam follower 51 drives the cup holder 30 to move downward in the vertical direction, so that the cup holder 1 and the steel shell 2 are separated. In this embodiment, in order to ensure that the steel shell 2 and the cup holder 1 are completely separated, the height difference between the lowest position and the highest position is greater than the depth to which the steel shell 2 is inserted into the cup holder 1.

[0034] Based on the above embodiments, as an optional implementation method, combined with Figure 4As shown, the ejector assembly 50 also includes a guide frame and a mounting plate 52. The guide frame passes through the first turntable 11, and the cam follower 51 is located at the lower end (i.e., the second end) of the guide frame. The mounting plate 52 is located on the guide frame and between the upper end (i.e., the first end) and the lower end of the guide frame. The cup holder 30 is mounted on the mounting plate 52 to connect the cup holder 30 and the ejector assembly 50. Specifically, the guide frame includes guide rods 53, a first connecting block 54, and a second connecting block 55. The two guide rods 53 are spaced apart and parallel to each other. Both guide rods 53 pass through the first turntable 11 in a vertical direction. The upper ends of the guide rods 53 extend above the steel shell fixture 40, and the upper ends of the two guide rods 53 are connected by the first connecting block 54. The lower ends of the guide rods 53 are located below the second turntable 12, and the lower ends of the two guide rods 53 are connected by the second connecting block 55. The cam follower 51 is located on the second connecting block 55. Therefore, the guide frame and mounting plate 52 with the above structure can improve the stability of the connection between the cup holder 30 and the guide frame, and can improve the smoothness of the cam follower 51 and the cup holder 30 rising and falling in the vertical direction.

[0035] Based on the above embodiments, as an optional implementation, a magnetic suction element is provided on the side of the steel shell fixture 40 facing the placement position of the steel shell 2. The magnetic suction element is used to attract the side wall of the steel shell 2. Specifically, an adsorption groove is provided on the side of the steel shell fixture 40 facing the placement position of the steel shell 2. The adsorption groove is used to accommodate the steel shell 2. The shape of the adsorption groove matches the shape of the outer side wall of the steel shell 2. A magnetic suction element is provided on the inner wall of the steel shell fixture 40. The steel shell 2, which is accommodated in the adsorption groove, is attracted by the magnetic suction element, so that the steel shell 2 can be stably attracted to the magnetic suction element, thereby enabling the steel shell fixture 40 to clamp the steel shell. Thus, by setting the magnetic suction element to attract the steel shell 2, the steel shell fixture 40 clamps the steel shell 2. When separating the steel shell 2 and the steel shell fixture 40, it is beneficial to reduce the friction between the steel shell 2 and the steel shell fixture 40, thereby further reducing the wear on the outside of the steel shell. As an optional implementation, the magnetic suction element is a magnet.

[0036] Based on the above embodiments, as an optional implementation, the steel shell ejection device further includes a drive component 70, which is connected to the rotating shaft 20 and drives the rotating shaft 20 to rotate. Thus, by driving the rotating shaft 20 to rotate via the drive component 70, the rotating shaft 20 drives the first turntable 11 and the second turntable 12 to rotate synchronously, causing the cup holder 30, the steel shell holder 40, the ejection assembly 50, and the cup 1 and steel shell 2 to rotate together with the rotating shaft 20, achieving periodic movement of the cup 1 and steel shell 2. As an optional implementation, the drive component 70 can be a motor, and can be coupled with a transmission component such as a transmission wheel or a synchronous belt to achieve a transmission connection.

[0037] The following is combined with Figures 1 to 3The working principle of the steel shell ejection device provided in this embodiment is explained as follows:

[0038] After transferring cup 1 and steel shell 2 from the previous station to cup holder fixture 30 and steel shell fixture 40, drive component 70 drives rotating shaft 20 to rotate. Rotating shaft 20 drives first turntable 11 and second turntable 12 to rotate synchronously, so that cup holder fixture 30, steel shell fixture 40, cup ejection assembly 50, and cup 1 and steel shell 2 rotate together with rotating shaft 20. At this time, cam follower 51 will move along guide ramp 61. When cam follower 51 rolls from the second ramp section to the first ramp section, the cam follower... The actuator 51 drives the cup holder 30 to move vertically downward, increasing the distance between the cup holder 1 and the steel shell 2, separating the cup holder 1 and the steel shell 2. The cup holder 1 is then transferred to the next station, and the steel shell 2 is removed from the steel shell fixture 40, separating the steel shell 2 from the steel shell fixture 4. The steel shell 2 is then transferred to the next station. Subsequently, the rotating shaft 20 continues to drive the cup holder 30, the steel shell fixture 40, and the ejector assembly 50 to rotate, performing the next feeding of the cup holder 1 and the steel shell 2, and repeating the above operations.

[0039] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
