Description

Technical Field

[0001] The utility model belongs to the technical field of battery manufacturing, and particularly relates to a concentric positioning device for a battery core to enter a shell. Background Art

[0002] In actual battery production, due to parameter fluctuations of incoming pole pieces, the produced bare battery cores are not completely of the same specification. The fluctuations in the specifications of the bare battery cores, and even the outer diameters of the same bare battery core itself will also vary. For example, the outer diameter of the middle part of a cylindrical bare battery core is larger than that of the two ends, thus forming a bulge at the middle position of the bare battery core.

[0003] During the process of most bare battery cores entering the shell, the aluminum shell is horizontally fixed on one side, and the bare battery core is pushed into the shell through a push rod via a horizontal slideway. Due to the reasons of the actual specifications of the bare battery cores described above, during the process of entering the shell, the inconsistent horizontal heights of the bare battery cores will cause collisions between the bare battery cores and the shell, resulting in scrapping. This phenomenon is particularly serious when switching battery models. Currently, when changing battery models, the equipment accuracy is usually rectified by using the multiple shell-entry debugging of the bare battery cores, which will cause a large amount of waste, and the adjustment period is relatively long, affecting production capacity. Summary of the Invention

[0004] The purpose of the utility model is to provide a concentric positioning device for a battery core to enter a shell, so as to solve the problems existing in the above background art.

[0005] The purpose of the utility model is realized as follows: a concentric positioning device for a battery core to enter a shell, which includes a shell support frame. A shell is placed on the upper side of the shell support frame. A concentric positioner is arranged on the right side of the shell support frame. An annular clamp is arranged in the middle of the concentric positioner. A bare battery core is placed inside the annular clamp.

[0006] A rotating bracket is arranged between the shell support frame and the shell.

[0007] An eccentric adjustment knob is arranged on the right side of the shell support frame.

[0008] The concentric positioner includes a housing. A ring gear is arranged inside the housing. A rotation adjustment knob is arranged on the left side of the ring gear. A push rod is arranged on the right side of the ring gear. The push rod is connected to the annular clamp.

[0009] The rotation adjustment knob meshes with the ring gear. The push rod is screwed to the ring gear.

[0010] A motor is arranged on the outer side of the rotation adjustment knob.

[0011] The annular clamp is composed of symmetrically arranged separating clips.

[0012] Advantages of the present utility model: Through the design of the concentric positioner, especially by utilizing the screwed connection structure of the annular gear and the push rod, combined with the precise control of the rotary adjustment knob, this device can ensure extremely high concentricity when the bare battery cell is placed into the housing. The bare battery cell always remains at the center position of the housing, avoiding collisions, and being concentrically positioned into the housing, which is beneficial to the welding strength of the subsequent bottom-through welding; the eccentric adjustment knob and the rotary bracket provided in the device allow for fine adjustment of the housing to adapt to bare battery cells and housings of different specifications or with slight deformations, thereby simplifying the assembly process and reducing the requirements for the skills of operators; by arranging a motor outside the rotary adjustment knob, automatic or semi-automatic control of the process of inserting the bare battery cell into the housing can be achieved, which not only reduces manual intervention but also lowers the labor intensity; the high-precision concentric positioning and the flexible assembly mechanism together ensure a tight fit between the bare battery cell and the housing, reducing performance degradation or safety hazards caused by improper assembly; the concentric positioning method is compatible with abnormal situations such as bulging of the bare battery cell, not limited to the size specifications of the bare battery cell, not limited to the horizontal insertion method into the housing, and any insertion method can be used.

[0018] The following further describes the present utility model with reference to the drawings. Embodiment

[0019] As Figures 1-4As shown in the figure, a concentric positioning device for a battery cell to be inserted into a casing includes a casing support 1. A casing 2 is placed on the upper side of the casing support 1. A concentric positioner 3 is arranged on the right side of the casing support 1. An annular clamp 4 is arranged in the middle of the concentric positioner 3. A bare battery cell 5 is placed inside the annular clamp 4.

[0020] A rotating bracket 6 is arranged between the casing support 1 and the casing 2.

[0021] An eccentric adjustment knob 7 is arranged on the right side of the casing support 1.

[0022] When the present utility model is in use, first, the annular clamp 4 inside the concentric positioner 3 is fully opened to facilitate the reception of the bare battery cell 5. The bare battery cell 5 is sent into the annular clamp 4 inside the concentric positioner 3. The concentric positioner 3 controls the annular clamp 4 to close. Since the annular clamp 4 is concentric with the casing 2, at this time, the bare battery cell 5 is also concentric with the casing 2, realizing concentric positioning. Then, the bare battery cell 5 is pushed into the casing 2 by an external robotic arm to complete the concentric insertion into the casing work. The purpose of this device is to optimize the assembly process, reduce the assembly time, and improve the production efficiency. At the same time, since the rework and scrap rate caused by assembly errors are reduced, the production cost is also indirectly reduced. Embodiment

[0023] As Figures 1-4 As shown in the figure, a concentric positioning device for a battery cell to be inserted into a casing includes a casing support 1. A casing 2 is placed on the upper side of the casing support 1. A concentric positioner 3 is arranged on the right side of the casing support 1. An annular clamp 4 is arranged in the middle of the concentric positioner 3. A bare battery cell 5 is placed inside the annular clamp 4.

[0024] For better effect, a rotating bracket 6 is arranged between the casing support 1 and the casing 2. The rotating bracket 6 can drive the casing 2 to rotate. When the winding diameter of the bare battery cell 5 is relatively large, by rotating the casing 2, the friction resistance can be reduced to facilitate the insertion into the casing.

[0025] For better effect, an eccentric adjustment knob 7 is arranged on the right side of the casing support 1. The eccentric adjustment knob 7 can be used to adjust the horizontal height of the casing 2 to adjust its level with the concentric positioner 3.

[0026] For better effect, the concentric positioner 3 includes a housing 8. A ring gear 9 is arranged inside the housing 8. A rotation adjustment knob 10 is arranged on the left side of the ring gear 9. A push rod 11 is arranged on the right side of the ring gear 9. The push rod 11 is connected to the annular clamp 4.

[0027] For better effect, the rotation adjustment knob 10 meshes with the ring gear 9, and the push rod 11 is screwed with the ring gear 9.

[0028] For better effect, a motor 13 is arranged outside the rotary adjustment knob 10. According to actual needs, the motor 13 can be connected to the rotary adjustment knobs 10 in different orientations. The motor 13 drives the rotary adjustment knob 10 to rotate, which can drive the push rod 11 to move forward or backward, thereby realizing the opening and closing of the annular fixture 4.

[0029] For better effect, the annular fixture 4 is composed of symmetrically arranged separating clips 12. This design enables the annular fixture 4 to flexibly adapt to naked battery cells 5 of different sizes, and also facilitates the rapid installation and disassembly of the naked battery cells 5.

[0030] When the utility model is in use, first, the annular fixture 4 inside the concentric positioner 3 is fully opened to facilitate the reception of the naked battery cell 5. The naked battery cell 5 is sent into the annular fixture 4 inside the concentric positioner 3. The concentric positioner 3 controls the annular fixture 4 to close. Since the annular fixture 4 is concentric with the housing 2, at this time, the naked battery cell 5 is also concentric with the housing 2, realizing concentric positioning. Subsequently, the naked battery cell 5 is pushed into the housing 2 by an external robotic arm to complete the concentric housing insertion work. Further, the structure of the concentric positioner 3 is preferably: start the motor 13, drive the rotary adjustment knob 10 to rotate through the motor 13, and then drive the annular gear 9 to rotate. Since the push rod 11 is screwed to the annular gear 9, the rotation of the annular gear 9 will be converted into the linear motion of the push rod 11, and the annular fixture 4 will gradually approach the naked battery cell 5 along with the linear motion of the push rod 11, thereby adjusting the positions of the annular fixture 4 and the naked battery cell 5. This concentric positioning device can efficiently and accurately complete the concentric positioning and assembly work of the naked battery cell 5 and the housing 2. This device aims to optimize the assembly process, reduce the assembly time, and improve the production efficiency. At the same time, since the rework and scrap rate caused by assembly errors are reduced, the production cost is indirectly reduced.
