[0001] This utility model relates to the field of battery production equipment technology, and more specifically to a battery processing positioning fixture. Background Technology

[0002] Clamps are ubiquitous in lithium battery manufacturing plants, especially in the production stations of prismatic or pouch batteries. They serve as battery pressing and positioning clamps, which, in addition to their positioning function, also play a role in pressing the battery, i.e., pressing one end of the battery to compress its length to within the standard design dimensions for that process. Chinese patent (CN220389213U) discloses "a positioning fixture for lithium battery processing." This patent uses a fixed clamp and a movable clamp to form a battery clamp on a base plate. It also includes a coarse adjustment component that can lock the base plate and allow for free sliding adjustment after unlocking. The coarse adjustment component adjusts the position of the movable clamp according to the battery size. Then, the fine adjustment component adjusts the position of the movable clamp to accurately clamp the battery workpiece. It can also be used as a tool for adjusting and pressing the battery length, making it more convenient to use, faster to operate, reducing labor, and improving production efficiency.

[0003] However, the existing tooling still has some defects in use: for example, the clamp still needs to be adjusted manually when adjusting according to the battery size, and there is still room for improvement in work efficiency. Secondly, when clamping the battery, it is not easy to control the clamping force, which can easily lead to excessive clamping force and damage to the battery. Utility Model Content

[0020] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Reference Figure 1 and Figure 2 This utility model provides a battery processing positioning fixture, including a base plate 1, a fixed clamping plate 6 fixedly installed on the top of the base plate 1, a sliding groove opened on the top of the base plate 1, a slider 3 slidably sleeved in the sliding groove, a displacement mechanism 2 fixedly connected to the bottom of the base plate 1, the output end of the displacement mechanism 2 fixedly connected to the bottom of the slider 3, a connecting arm assembly 4 fixedly connected to the top of the slider 3, a movable clamping plate 7 fixedly installed at one end of the connecting arm assembly 4, the fixed clamping plate 6 fixedly connected to the top of the base plate 1, and a motor 5 fixedly installed on the top of the base plate 1, the output end of the motor 5 penetrating the base plate 1 and docking with the displacement mechanism 2; the connecting arm assembly 4 is used for pressure buffering and detection of the movable clamping plate 7, and a controller is provided at the bottom of the base plate 1, the controller docking with the connecting arm assembly 4 and the motor 5.

[0022] In use, the battery processing part is placed on top of the base plate 1. The motor 5 drives the displacement mechanism 2 to slide the slider 3. Under the connection effect of the connecting arm assembly 4, the movable clamping plate 7 is moved to adjust the distance between the fixed clamping plate 6 and the movable clamping plate 7. The fixed clamping plate 6 and the movable clamping plate 7 then clamp the battery. When the clamping force of the fixed clamping plate 6 and the movable clamping plate 7 is too large, the connecting arm assembly 4 can achieve a buffering effect to reduce the clamping force of the fixed clamping plate 6 and the movable clamping plate 7 and prevent damage to the battery processing part. At the same time, the connecting arm assembly 4 can also detect the pressure and send a pressure signal to the controller. When the pressure value is too high, the controller can control the motor 5 to stop running, achieving the effect of automatic positioning of the distance between the fixed clamping plate 6 and the movable clamping plate 7, improving the ease of operation of this tooling.

[0023] Reference Figure 2 The displacement mechanism 2 includes two end plates 21, which are fixedly connected to the bottom of the base plate 1. A threaded shaft 22 is rotatably sleeved on the inner side of the two end plates 21. A moving block 23 is threadedly sleeved on the side wall of the threaded shaft 22. The top of the moving block 23 is fixedly connected to the bottom of the slider 3. One end of the threaded shaft 22 is connected to the output end of the motor 5 through a bevel gear meshing group 24.

[0024] In use, the motor 5 runs through the bevel gear meshing group 24 to drive the threaded shaft 22 to rotate. Under the action of the threaded structure, the moving block 23 can be displaced. The displacement of the moving block 23 can drive the slider 3 to slide, thereby achieving the displacement output effect of the displacement mechanism 2.

[0025] Reference Figure 3 The connecting arm assembly 4 includes: a connecting plate 41 and a connecting block 43. A movable shaft 42 is fixedly connected to one side of the connecting plate 41. The connecting block 43 is slidably sleeved on the side wall of the movable shaft 42. A pressure ring 44 is slidably sleeved on the side wall of the movable shaft 42. A pressure sensor 46 is provided on one side of the connecting plate 41. The pressure ring 44 is in contact with the detection end of the pressure sensor 46. The other side of the pressure ring 44 is connected to the connecting block 43 via a spring 45. The connecting block 43 is fixedly connected to the top of the slider 3. The other side of the connecting plate 41 is fixedly connected to one side of the movable clamping plate 7. The pressure sensor 46 is electrically connected to the controller.

[0026] When the clamping force of the fixed clamping plate 6 and the movable clamping plate 7 is too large, the connecting plate 41 pushes the pressure ring 44 through the pressure sensor 46. During this process, the pressure ring 44 compresses the spring 45. Through the reaction force of the spring 45, the connecting plate 41 applies pressure to the movable clamping plate 7 to ensure the clamping force of the fixed clamping plate 6 and the movable clamping plate 7. This avoids the problem of excessive clamping force of the fixed clamping plate 6 and the movable clamping plate 7. During this process, the greater the movement distance of the pressure ring 44, the greater the pressure on the spring 45. Conversely, the greater the pressure value detected by the pressure sensor 46, the smaller the movement distance.

[0027] Reference Figure 3 Two side arms 47 are fixedly connected to one side of the connecting plate 41, and the connecting block 43 is slidably sleeved on the side wall of the two side arms 47.

[0028] The stability of the pressure sensor 46 can be improved by setting two side arms 47.

[0029] Reference Figure 2 , 4 The fixed clamping plate 6 and the movable clamping plate 7 have the same structure. The movable clamping plate 7 includes a main plate 71. A fixed lug block 72 is fixedly connected to one side of the main plate 71. A rail groove 73 is opened on the side wall of the main plate 71. A movable column block 75 is slidably sleeved on the inner wall of the rail groove 73. A threaded shaft 74 is rotatably sleeved inside the rail groove 73. The movable column block 75 is threadedly sleeved on the side wall of the threaded shaft 74. A handle 77 is provided at the back end of the main plate 71 and connected to one end of the threaded shaft 74. A movable lug block 76 is fixedly connected to one side of the movable column block 75.

[0030] By rotating the handle 77, the threaded shaft 74 is rotated. Under the influence of the threaded structure, the movable column 75 can be displaced, thereby adjusting the distance between the fixed lug 72 and the movable lug 76. This allows the fixed lug 72 and the movable lug 76 to provide a lateral clamping effect on the battery, thereby improving the stability of the battery processing parts clamping.

[0031] Reference Figure 5 The movable column block 75 includes a main movable column 751, with anti-detachment end blocks 752 fixedly connected to both ends of the main movable column 751. A sleeve block 753 is slidably sleeved on the side wall of the main movable column 751. The sleeve block 753 is connected to the anti-detachment end block 752 through a spring 754. The sleeve block 753 is slidably sleeved in the rail groove 73. A movable lug block 76 is fixedly connected to one side of the sleeve block 753.

[0032] When the clamping force of the fixed lug block 72 and the movable lug block 76 is too great, the sleeve block 753 will slide on the side wall of the main moving column 751 to compress the spring 754, thereby buffering the clamping force between the fixed lug block 72 and the movable lug block 76 and avoiding damage to the battery processing parts.

[0033] Reference Figure 5 The main movable column 751 is set as a polygon.

[0034] This design prevents the main moving column 751 from rotating within the sleeve block 753, while the sleeve block 753 cannot rotate within the rail groove 73. This prevents the threaded shaft 74 from rotating due to friction, causing the main moving column 751 to rotate.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
