[0033] The utility model embodiment proposes a battery roll core's into shell fixture 100, be configured for assisting battery roll core installs into battery shell 10. Among them, the battery involved can be button cell, including but not limited to this.

[0034] Referring to Figures 1 to 4 The battery roll core into shell fixture 100 includes:

[0035] The base 110 is provided with a placing position for placing the battery shell 10.

[0036] The guide plate 120 is connected with the base 110, and the guide plate 120 is provided with a guide groove 121. The guide plate 120 is provided with an inlet slot 121A for the battery roll core to enter the guide groove 121 on the side away from the base 110. The guide plate 120 is provided with an outlet slot 121B for the battery roll core to exit from the guide groove 121 on the side facing the base 110. The outlet slot 121B is opposite to the placing position, and the inner diameter of the outlet slot 121B is smaller than the inner diameter of the shell opening of the battery shell 10.

[0037] As Figures 1 to 3 The base 110 is the basic support structure of the whole fixture, and is in the shape of a seat body. The shape and size of the placing position provided on the base 110 are matched with the battery shell 10, for stably supporting the battery shell 10 to prevent displacement during the shell entering operation. For example, the placing position can be provided as a groove with a certain depth on the upper surface of the base 110. The inner wall of the groove is closely combined with the outer wall of the battery shell 10. Optionally, a buffer pad can be provided at the bottom of the groove to reduce the impact force when the battery shell 10 is placed and further improve the stability.

[0038] The guide plate 120 is located above the base 110, and the shape of the guide groove 121 on the guide plate 120 is matched with the contour of the battery roll core, and the guide plate 120 is used to guide the battery roll core into the battery shell. The inner wall of the guide groove 121 can be treated with smoothing, which can effectively reduce the friction resistance of the battery roll core when moving in the guide groove 121, and ensure the smooth passing of the battery roll. The inner diameter of the inlet slot 121A can be greater than the outer diameter of the battery roll core, so that the battery roll core can smoothly enter the guide groove 121. The inner diameter of the outlet slot 121B is smaller than the inner diameter of the shell opening of the battery shell 10, and after the battery roll core is guided out of the outlet slot 121B, it can accurately fall into the battery shell 10.

[0039] The guide plate 120 is connected with the base 110, and the guide plate 120 can be detachably arranged on the base 110, or can be arranged in a lifting manner. In the assembly process of the battery roll core into the shell, the guide plate 120 can be removed or moved to form an operation space above the base 110 for loading or unloading the battery shell 10, so as to facilitate the loading or unloading of the battery shell 10.

[0040] The working principle of the battery roll core into the shell jig 100 is as follows:

[0041] The battery shell 10 is placed at the placement position of the base 110, and the guide plate 120 is located above the battery shell 10 on the base 110. When the battery roll core is assembled, the battery roll core is placed into the guide groove 121 from the inlet slot 121A of the guide plate 120, and the battery roll core moves in the guide groove 121 by relying on its own gravity or a slight pushing force applied from outside. When reaching the outlet slot 121B, since the battery shell 10 is located opposite to the outlet slot 121B, the battery roll core can be accurately and correctly assembled into the battery shell 10 from the shell opening of the battery shell 10, and the process of the battery roll core into the shell is completed. The assembly operation can be completed by a mechanical hand or by manual operation, and the present embodiment does not limit this.

[0042] The inner diameter of the outlet slot 121B is smaller than the inner diameter of the shell opening of the battery shell 10, and under the limiting action of the outlet slot 121B, when the battery roll core is guided out of the outlet slot 121B, the outer diameter of the battery roll core is correspondingly smaller than the inner diameter of the shell opening of the battery shell 10, so that the battery roll core can be accurately and smoothly assembled into the battery shell 10, and the battery roll core will not be scratched by the shell at the shell opening of the battery shell 10, so as to protect the battery roll core from being damaged in the process of entering the shell, thereby ensuring the quality of battery production.

[0043] In some embodiments, with reference to Figure 2 and Figure 4The caliber of the entry slot 121A gradually decreases from large to small along the entering direction of the battery winding core. The caliber of the entry slot 121A gradually decreasing from large to small along the entering direction of the battery winding core has significant advantages. When the battery winding core approaches the entry slot 121A, the larger caliber can provide a more generous guiding space, facilitating the quick and accurate alignment of the battery winding core to the entry slot 121A. Moreover, when the battery winding core is deformed, tilted or offset, the entry slot 121A can reshape and correct the battery winding core as the battery winding core continuously enters the entry slot 121A. The battery winding core is reshaped to a standard shape (e.g., a circular shape) and simultaneously corrected to the center position of the guide slot 121. For example, the entry slot 121A is a circular ring-shaped horn, and the periphery of the entry slot 121A forms a smooth transition arc surface. At the starting end of the entry slot 121A, the caliber can be designed to be 1mm-2mm larger than the outer diameter of the battery winding core. As the battery winding core enters deeper in the entering direction, the caliber gradually decreases until it smoothly transitions with the inner diameter of the guide slot 121. This design can effectively avoid the battery winding core from being stuck or colliding due to caliber mutation when entering the entry slot 121A, ensuring that the battery winding core can smoothly enter the guide slot 121.

[0044] In some embodiments, with reference to Figure 2 and Figure 4 The base 110 is provided with a guide column 111, and the guide plate 120 is provided with a guide hole 122 matched with the guide column 111. The guide column 111 extends into the guide hole 122 to form a sliding fit with the guide hole 122.

[0045] The guide plate 120 is arranged to be liftable on the base 110, and the guide plate 120 can move up or down relative to the base 110. Specifically, the guide plate 120 can be raised to move away from the base 110 to place or take out the battery shell 10, and the guide plate 120 can be lowered to move close to the base 110 to align the exit slot 121B with the battery shell 10. During the battery winding process, the movement of the guide plate 120 can be achieved by a driving structure or manually operated by a person, which is not limited in the present embodiment. Moreover, the base 110 and the guide plate 120 are in sliding fit through the guide column 111 and the guide hole 122, which can ensure the fitting accuracy and the position accuracy of the guide plate 120 during the lowering process of the guide plate 120, thereby improving the alignment accuracy of the exit slot 121B and the battery shell 10.

[0046] In some embodiments, with reference to Figure 2 and Figure 4The number of guide posts 111 is at least two, and the at least two guide posts 111 are arranged on the circumferential side of the placement position. For example, when the number of guide posts 111 is two, the two guide posts 111 are arranged in opposition on the circumferential side of the placement position. When the number of guide posts 111 is three, the three guide posts 111 are arranged in an equilateral triangle on the circumferential side of the placement position. The number and position of the guide holes 122 are arranged in correspondence with the number and position of the guide posts 111. In this embodiment, the plurality of guide posts 111 are arranged to further improve the cooperation precision of the base 110 and the guide plate 120 and the position precision of the guide plate 120.

[0047] In some embodiments, with reference to Figure 4 and Figure 5 One side of the guide plate 120 facing the base 110 is concavely provided with a guide groove 123, and the outlet opening 121B is located at the groove bottom wall of the guide groove 123 and communicates with the guide groove 123.

[0048] The guide groove 123 is used for the battery shell 10 to extend into the guide groove 123 to guide the battery shell 10, and the inner diameter of the guide groove 123 gradually increases from small to large along the direction of the battery core.

[0049] Before the battery core is assembled, the guide plate 120 is controlled to descend to align the outlet opening 121B with the battery shell 10, wherein when the guide plate 120 descends to a preset position, the battery shell 10 partially extends into the guide groove 123. Due to the gradual change of the inner diameter of the guide groove 123, when the battery shell 10 is inclined or deviated, the battery shell 10 will be gradually guided to the center position of the guide groove 121 during the extension into the guide groove 123, so as to facilitate the rapid and accurate alignment of the outlet opening 121B with the battery shell 10. Moreover, the guide groove 123 can limit the battery shell 10 to prevent the battery shell 10 from shaking or moving during the battery core entering the shell.

[0050] In some embodiments, the difference between the maximum inner diameter of the guide groove 123 and the outer diameter of the battery shell 10 is in the range of 0.005mm-0.015mm.

[0051] The difference between the inner diameter of the battery shell 10 and the inner diameter of the outlet opening 121B is in the range of 0.005mm-0.015mm.

[0052] In the embodiment, the difference between the maximum outer diameter of the guide groove 123 and the outer diameter of the battery shell 10 can be set in the range of 0.005mm-0.015mm. For example, the difference between the maximum outer diameter of the guide groove 123 and the outer diameter of the battery shell 10 can be 0.005mm, 0.01mm or 0.015mm, etc. Preferably, the difference between the maximum outer diameter of the guide groove 123 and the outer diameter of the battery shell 10 is 0.01mm. This small difference design can ensure that the battery shell 10 can smoothly extend into the guide groove 123 for guidance, while controlling the position deviation of the shell within a very small range, ensuring accurate cooperation with the guide groove 121 and subsequent shell entering action.

[0053] At the same time, the difference between the inner diameter of the battery shell 10 and the inner diameter of the outlet slot 121B can be set in the range of 0.005mm-0.015mm. For example, the difference between the inner diameter of the battery shell 10 and the inner diameter of the outlet slot 121B can be 0.005mm, 0.01mm or 0.015mm, etc. Preferably, the difference between the inner diameter of the battery shell 10 and the inner diameter of the outlet slot 121B is 0.01mm. This small difference design can ensure that the battery roll core accurately falls into the battery shell 10 after being guided out of the outlet slot 121B without scratching the battery shell 10, while also ensuring the originally small cooperation gap between the battery roll core and the battery shell 10.

[0054] In some embodiments, the base 110 is provided with a driving member, and the output execution end of the driving member is connected with the guide plate 120, for driving the guide plate 120 to move up and down. In the embodiment, the guide plate 120 moves up and down through the driving of the driving member, without manual operation, which is convenient, time-saving and labor-saving, and helps to improve the battery core loading efficiency. The driving member can be a driving cylinder, the cylinder body of which is fixed on the base 110, and the piston rod of the driving cylinder is connected with the guide plate 120. The driving member adopts the driving cylinder, which has the advantages of simple structure, low cost and reliable work. In addition, the driving member can also adopt other types, which are not limited in the embodiment.

[0055] In some embodiments, referring to Figure 2 and Figure 4The base 110 is provided with a receiving groove 112 located at the placement position and used for accommodating the battery shell 10. The shape and size of the receiving groove 112 can be designed according to the contour of the battery shell 10. For example, the battery shell 10 is in a cylindrical shape, and the receiving groove 112 is designed as a cylindrical recess matching the battery shell 10, and the inner diameter of the receiving groove 112 is slightly larger than the outer diameter of the battery shell 10, for example, 0.05mm-0.1mm, so that the battery shell 10 can be smoothly placed in the receiving groove 112. The depth of the receiving groove 112 can be set according to actual needs, which is not limited in the embodiment. When the battery shell 10 is accommodated in the receiving groove 112, the positioning of the battery shell 10 before the battery core is put into the shell can be realized, and the stability of the battery shell 10 placed on the base 110 can be ensured, which is beneficial to the subsequent cooperation with the guide plate 120 and other components to put the battery core into the shell.

[0056] In some embodiments, referring to Figure 4 The middle axis of the guide groove 121 is arranged in line with the middle axis of the receiving groove 112. In the process of assembling the battery, the battery shell 10 is accurately placed in the receiving groove 112 of the base 110. Due to the good design of the receiving groove 112, the battery shell 10 can be stably positioned on the middle axis. Since the middle axis of the guide groove 121 is arranged in line with the middle axis of the receiving groove 112, the battery core always maintains the coaxial state with the battery shell 10 when moving in the guide groove 121. When the battery core reaches the outlet 121B, it can be accurately put into the battery shell 10, completing the accurate operation of putting the battery core into the shell. The design of arranging the middle axis of the guide groove 121 in line with the middle axis of the receiving groove 112 effectively solves the coaxiality problem in the process of putting the battery core into the shell, greatly improves the consistency and quality stability of the battery product, and reduces the rate of defective products caused by deviation in the process of putting the battery core into the shell.
