[0040] In some embodiments of the present application, a carrying jig 1 is provided, referring to Figures 1-11 , the carrying jig 1 includes a base 10, a carrier plate 20, and a support shaft 30.

[0041] Referring to Figure 1 , Figures 3-5 and Figures 10-11 , the base 10 is in the shape of a plate body, the base 10 has a thickness direction X, and the base 10 includes a first surface 11 and a second surface 12 oppositely arranged along the thickness direction X.

[0042] Referring to Figures 1-4 and Figures 10-11 , the carrier plate 20 is arranged spaced apart from the base 10 along the thickness direction X, referring to Figures 1-4 , Figures 6-7 and Figures 10-11 , the carrier plate 20 includes a first surface 21 and a second surface 23 oppositely arranged along the thickness direction X, the first surface 21 faces the base 10 along the thickness direction X, referring to Figures 10-11 , the second surface 23 of the carrier plate 20 is used to carry a battery 200.

[0043] Referring to Figures 1-4 and Figures 10-11 , the support shaft 30 is arranged between the base 10 and the carrier plate 20, one end of the support shaft 30 along the thickness direction X is connected with the base 10, and the other end is connected with the carrier plate 20, in particular, referring to Figures 1-4 and Figures 8-11 , the support shaft 30 includes a first end 31 and a second end 34 oppositely arranged along the thickness direction X, the second end 34 is connected with the base 10, and the first end 31 is adjacent to the carrier plate 20 along the thickness direction X, the support shaft 30 is connected with the carrier plate 20 through the first end 31.

[0044] Wherein, the carrier plate 20 can rotate with the support shaft 30 as a reference, and the support shaft 30 can lock the carrier plate 20 to prevent the carrier plate 20 from rotating. In other words, the carrier plate 20 is connected with the first end 31 of the support shaft 30 along the thickness direction X, the carrier plate 20 can rotate with the first end 31 as a reference, and the support shaft 30 can lock the carrier plate 20 to prevent the carrier plate 20 from rotating, so as to fix the carrier plate 20, so that the carrier plate 20 is in a fixed position.

[0045] 3C electronic products, namely computer (Computer) products, communication (Communication) products and consumer electronics (Consumer Electronics) products, the battery in the production and assembly process, need to be fixed by the jig to fix the battery with the circuit board and other components, so as to carry out the subsequent welding, connection and test process, in different process, need to adjust the orientation direction of the battery and circuit board and other components, in order to carry out the welding, connection and test process, but the existing jig design is usually single, each jig can only be fixed for the battery with the circuit board and other components for a specific process, unable to meet the angle adjustment requirement of the battery with the circuit board and other components in multiple processes, for example, the jig in the welding process cannot meet the angle required for the battery with the circuit board and other components in the test process. The test process needs to place the battery with the circuit board and other components on the specific jig of the test process, so as to cause the need to use multiple different jigs to meet the angle adjustment requirement of different processes in the production and assembly and test process of the battery, and further cause the cost increase of the production and assembly and test of the battery, and increase the complexity of the production and assembly and test process, affect the production efficiency and test efficiency of the battery.

[0046] The bearing jig 1 provided by the embodiment of the present application is provided with a base 10, a carrier plate 20 and a support shaft 30. The base 10 and the carrier plate 20 are arranged in a thickness direction X of the base 10. The support shaft 30 is arranged between the base 10 and the carrier plate 20. One end of the support shaft 30 is connected with the base 10 in the thickness direction X. The other end of the support shaft 30 is connected with the carrier plate 20. The carrier plate 20 can rotate with the support shaft 30 as a reference, so that the carrier plate 20 can move freely in multiple different directions relative to the support shaft 30, and then the second surface 23 of the carrier plate 20 can face different directions, so that the components such as the battery cell 210 and the circuit board 220 carried by the second surface 23 of the carrier plate 20 can be at different angles, so as to meet the angle adjustment requirements of different processes in the assembly and test processes of the battery 200. Moreover, the support shaft 30 can lock the carrier plate 20 to prevent the carrier plate 20 from rotating. That is, after the carrier plate 20 rotates with the support shaft 30 as a reference to meet the angle adjustment requirements of a process, the support shaft 30 can lock the carrier plate 20, so that the carrier plate 20 is fixed and no longer rotates with the support shaft 30 as a reference, thereby ensuring the stability of the components such as the battery cell 210 and the circuit board 220 in the process, improving the stability and accuracy of the battery 200 in the assembly process or the test process. In the next process, the carrier plate 20 can continue to rotate with the support shaft 30 as a reference to meet the angle adjustment requirements of the corresponding process. Therefore, by adjusting the facing direction of the carrier plate 20 and locking the carrier plate 20 by the support shaft 30, the angle adjustment requirements of different processes can be flexibly met. One bearing jig 1 can meet the assembly or test requirements in different processes, save the development, design and manufacturing costs of special jigs required in different processes, optimize the operation and assembly process of the battery 200 assembly and test processes, improve the efficiency of the battery 200 production, assembly and test, and reduce the production and assembly costs.

[0047] In some embodiments, the first surface 21 of the carrier plate 20 is provided with a first recess 221, and the first end 31 of the support shaft 30 is inserted into the first recess 221, so that the carrier plate 20 can rotate with the support shaft 30 as a reference. Therefore, the carrier plate 20 needs to have sufficient thickness, and the first recess 221 is formed on the first surface 21, so that the support shaft 30 is directly connected with the carrier plate 20. While supporting the carrier plate 20, the support shaft 30 enables the carrier plate 20 to rotate with the support shaft 30 as a reference. The structure is simple, and the manufacturing cost is reduced.

[0048] In some embodiments, referring to Figures 1-4 , Figure 7 and Figures 10-11 , the first surface 21 of the carrier plate 20 is provided with a connecting portion 22 protruding in the thickness direction X. Specifically, the first surface 21 is provided with the connecting portion 22 protruding in the direction towards the base 10. Referring to Figure 7, the first end of the connecting portion 22 away from the first surface 21 in the thickness direction X is provided with a first groove 221, referring to Figures 1-4 and Figures 10-11 , the first end 31 of the support shaft 30 is inserted into the first groove 221, and the connecting portion 22 can rotate with the first end 31 as the reference, so that the carrier plate 20 rotates with the support shaft 30 as the reference. The design of the connecting portion 22 and the provision of the first groove 221 on the connecting portion 22 enable the carrier plate 20 to be connected to the first end 31 of the support shaft 30 through the connecting portion 22, thereby ensuring the stability of the rotation of the carrier plate 20 with the support shaft 30 as the reference, avoiding direct contact between the carrier plate 20 body and the support shaft 30 to cause wear, and ensuring the service life of the carrier plate 20.

[0049] In some embodiments, the end surface of the first end 31 is an arc surface. The arc surface design can ensure the smoothness of the rotation of the connecting portion 22 with the first end 31 as the reference, thereby ensuring the smoothness of the overall rotation of the carrier plate 20 and ensuring the accurate positioning of the carrier plate 20 in the corresponding process to meet the angle adjustment requirements.

[0050] In some embodiments, referring to Figures 1-4 and Figures 8-11 , the support shaft 30 is provided with at least two protrusions 32 adjacent to the first end 31 in the thickness direction X. Specifically, the protrusions 32 are protrudingly arranged on the end of the support shaft 30 adjacent to the first end 31 in the direction away from the base 10. The at least two protrusions 32 surround the first end 31 in the circumferential direction of the support shaft 30, referring to Figures 1-4 , Figure 7 and Figures 10-11 , the first groove 221 includes a groove wall 222, and the groove wall 222 is provided with at least two insertion slots 223 away from the first surface 21 in the thickness direction X. The insertion slots 223 are U-shaped, and the at least two insertion slots 223 are arranged in the circumferential direction of the connecting portion 22, referring to Figure 1 , Figure 4 and Figure 10 , the first end 31 of the support shaft 30 is inserted into the first groove 221, and the protrusions 32 are inserted into the insertion slots 223. The support shaft 30 forms a lock for the carrier plate 20, preventing the carrier plate 20 from rotating with the support shaft 30 as the reference; the protrusions 32 are separated from the insertion slots 223, and the insertion slots 223 of the connecting portion 22 are separated from the blocking of the protrusions 32, so that the connecting portion 22 can rotate with the first end 31 as the reference.

[0051] Specifically as Figures 1-4 and Figures 8-11In the shown embodiment, the number of protrusions 32 is four, which are arranged in a circumferential direction of the support shaft 30 and surround the first end 31. Specifically, the protrusions 32 are arranged obliquely and protruding on the side wall of the support shaft 30 in a direction away from the base 10. The protrusions 32 are in the shape of blocks, one end of the protrusions 32 is connected with the support shaft 30, and the other end is inclined away from the support shaft 30. Specifically, as shown in Figures 1-4 , Figure 7 and Figures 10-11 In the shown embodiment, the number of slots 223 is four, which are arranged in a circumferential direction of the connecting portion 22. The carrier plate 20 is rotated about the first end 31 through the connecting portion 22. The carrier plate 20 is inclined so that at least one protrusion 32 is inserted into the slot 223 to form a clamping connection with the connecting portion 22. Through the clamping connection between the protrusion 32 and the connecting portion 22, the carrier plate 20 is locked to prevent the carrier plate 20 from continuing to rotate about the first end 31. Referring to Figures 10-11 , the carrier plate 20 meets the angle adjustment requirements in the corresponding assembly or test process, so that the assembly or test operation of the battery 200 carried by the second surface 23 of the carrier plate 20, such as the battery cell 210 and the circuit board 220, can be performed. If the next process operation is required, the carrier plate 20 is rotated so that all the protrusions 32 are separated from the slots 223. After the carrier plate 20 is rotated to meet the angle adjustment requirements of the corresponding process, the carrier plate 20 is inclined so that the protrusions 32 are inserted into the slots 223 to lock the carrier plate 20. Thus, the carrier plate 20 can meet the angle adjustment requirements of multiple processes, improving the convenience and efficiency of battery 200 assembly and testing.

[0052] In other implementations, the number of protrusions 32 and the number of slots 223 can be adjusted according to actual use requirements, so that the carrier plate 20 can meet the angle adjustment requirements of different processes.

[0053] In some embodiments, the connecting portion 22 is magnetically connected with the first end 31 of the support shaft 30 to ensure the stability of the connection between the connecting portion 22 and the first end 31, and to prevent the carrier plate 20 from falling off the support shaft 30 due to the separation of the connecting portion 22 and the first end 31.

[0054] In some embodiments, referring to Figures 1-4 and Figures 8-11 , the first end 31 of the support shaft 30 is provided with a support portion 33, which is arranged protruding in the thickness direction X on the first end 31. Specifically, the support portion 33 is arranged protruding on the first end 31 in a direction away from the base 10. At least two protrusions 32 surround the support portion 33 in the circumferential direction of the support shaft 30. In other words, the at least two protrusions 32 and the first end 31 together define a receiving cavity for accommodating the support portion 33. The support portion 33 is arranged in the receiving cavity. The surface adjacent to one end of the carrier plate 20 in the thickness direction X is a spherical surface, referring toFigures 1-4 and Figures 10-11 The support portion 33 is inserted into the first groove 221 of the connecting portion 22 along the thickness direction X, and the connecting portion 22 can rotate with the support portion 33 as the reference, so that the support shaft 30 rotates with the support portion 33 as the reference. As the first end 31 of the support shaft 30 extends along the thickness direction X, the arrangement of the support portion 33 can improve the degree of freedom and stability of the connecting portion 22 of the carrier plate 20 rotating with the support portion 33 as the reference, and further ensure that the carrier plate 20 meets the in-place accuracy requirements of the corresponding process angle adjustment. As shown in the embodiments of Figures 1-4 and Figures 8-11 The shape of the support portion 33 is a sphere or a hemisphere, the surface of the support portion 33 is a spherical surface, the four protruding portions 32 surround the support portion 33 along the circumferential direction of the support shaft 30, and the protruding portions 32 are integrally formed with the support portion 33.

[0055] In some embodiments, the support portion 33 is magnetically connected with the connecting portion 22.

[0056] In some embodiments, referring to Figure 7 , Figures 10-11 and Figures 1-4 , along the circumferential direction of the connecting portion 22, the slot wall 222 between the adjacent two insertion slots 223 forms an insertion portion 224, referring to Figures 8-11 and Figures 1-4 , along the circumferential direction of the support shaft 30, the insertion slot 320 is defined between the adjacent two protruding portions 32, referring to Figures 10-11 and Figure 8 , the insertion portion 224 is inserted into the insertion slot 320, the connecting portion 22 is connected with the protruding portion 32 of the support shaft 30 through the insertion portion 224, and the support shaft 30 forms a lock for the carrier plate 20 to prevent the carrier plate 20 from rotating. Thus, through the matching design of the insertion portion 224 on the connecting portion 22 of the carrier plate 20 and the insertion slot 320 between the protruding portions 32, a lock for the rotation of the carrier plate 20 is formed, so that the carrier plate 20 meets the angle adjustment requirements in the corresponding assembly or test process, so as to perform assembly or test operation on the battery cell 210 and the circuit board 220 and other components carried by the second surface 23 of the carrier plate 20.

[0057] In addition, the structure design that the protruding portion 32 is inserted into the insertion slot 223 cooperates with the structure design that the insertion portion 224 is inserted into the insertion slot 320, so that the connecting portion 22 of the carrier plate 20 and the protruding portion 32 of the support shaft 30 form a mutual engagement and meshing connection mode, thereby further improving the locking stability and firmness of the support shaft 30 for the carrier plate 20, improving the stability of the carrier plate 20 to maintain the required angle in the corresponding process, and ensuring the assembly and test effect and efficiency of the battery 200.

[0058] In some embodiments, referring toFigures 1-4 The support portion 33 includes two surfaces 330 arranged opposite along the thickness direction X, the interval of the two surfaces 330 along the thickness direction X is S mm, the interval between the end surface of the support portion 33 along the thickness direction X away from one end of the base 10 and the end surface of the convex portion 32 along the thickness direction X away from one end of the base 10 is L mm, and the following conditions are met: When the value of L is within the above range, the end of the support portion 33 along the thickness direction X away from the carrier plate 20 is connected with the convex portion 32, and the end of the support portion 33 along the thickness direction X adjacent to the carrier plate 20 can exceed the convex portion 32, so that the connecting portion 22 can rotate with the support portion 33 as the reference, and when it is necessary to lock the carrier plate 20, the convex portion 32 can be inserted into the slot 223, so that the carrier plate 20 meets the angle adjustment requirements of the corresponding work.

[0059] In some embodiments,

[0060] In some embodiments, referring to Figures 8-11 and Figure 7 In the embodiments shown in the embodiments, the shape of the support portion 33 is a sphere, and the value of S is the diameter of the support portion 33.

[0061] In some embodiments, referring to Figures 1-4 The first groove 221 further includes a groove bottom 225, and the groove wall 222 surrounds the groove bottom 225 along the circumferential direction of the connecting portion 22. The groove wall 222 and the groove bottom 225 are both arc surfaces. The structure design of the arc surfaces of the groove wall 222 and the groove bottom 225, in combination with the structure design of the spherical surface of the support portion 33 and the magnetic attraction connection between the connecting portion 22 and the support portion 33, can ensure the smoothness and stability of the rotation of the connecting portion 22 with the support portion 33 as the reference, and can ensure the connection stability between the connecting portion 22 and the support portion 33.

[0062] In some embodiments, referring to Figures 8-11 and Figure 1The support shaft 30 comprises a support portion 33 protruding from the first end 31 of the support shaft 30 along the thickness direction X, specifically, the support portion 33 protrudes from the first end 31 of the support shaft 30 away from the base 10, and the surface of the support portion 33 adjacent to one end of the carrier plate 20 along the thickness direction X is a spherical surface. The connecting portion 22 protrudes from the first surface 21 of the carrier plate 20 along the direction towards the base 10, and a first groove 221 is formed at one end of the connecting portion 22 away from the first surface 21. The support portion 33 is inserted into the first groove 221, and the support portion 33 is magnetically connected to the connecting portion 22. Under the action of an external force, the connecting portion 22 can rotate with the support portion 33 as the reference, so that the carrier plate 20 rotates with the support shaft 30 as the reference. When the external force is lost, the support portion 33 forms a magnetic locking to the connecting portion 22 to prevent the carrier plate 20 from rotating. In other words, only the support portion 33 is arranged on the first end 31 of the support shaft 30, and no protruding portion 32 is arranged on the support shaft 30. The connecting portion 22 on the carrier plate 20 is magnetically connected to the support portion 33. When it is necessary to rotate the carrier plate 20 to meet the angle adjustment requirements of the corresponding process, only an external force needs to be applied to the carrier plate 20, and the applied external force needs to be greater than the magnetic attraction force between the support portion 33 and the connecting portion 22, so that the carrier plate 20 rotates with the support portion 33 as the reference through the connecting portion 22 to meet the angle adjustment requirements of the corresponding process. Moreover, the magnetic connection between the support portion 33 and the connecting portion 22 enables the connecting portion 22 to remain connected to the support portion 33 during the rotation of the carrier plate 20, thereby avoiding separation of the carrier plate 20 from the support shaft 30. When the carrier plate 20 is rotated to meet the angle adjustment requirements of the corresponding process, only the external force applied to the carrier plate 20 needs to be removed. The carrier plate 20 loses the external force and is locked by the magnetic attraction between the connecting portion 22 and the support portion 33, thereby fixing the carrier plate 20 at an angle that meets the requirements of the corresponding process. Thus, the structure of the support shaft 30 is simplified, and the manufacturing cost of the carrier tool 1 is reduced.

The positioning posts 24 can improve the installation accuracy of the battery 200 on the second surface 23 of the carrier plate 20, and the positioning posts 24 can limit the components such as the battery cell 210 and the circuit board 220 in the battery 200, preventing the battery 200 from moving or even falling off during the rotation of the carrier plate 20.
