[0023] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A common jig for detecting the appearance of a square lithium battery top cover comprises an X-axis fixing rod 1, a Y-axis fixing rod 2 and a battery top cover 11. The two ends of the two X-axis fixing rods 1 are interspersed with Y-axis fixing rods 2. A rectangular groove for the Y-axis fixing rod 2 to penetrate is cut on the side of each X-axis fixing rod 1, and a fixing screw 3 is symmetrically threaded inside the X-axis fixing rod 1 at the top of the rectangular groove. Threaded holes matching the fixing screw 3 are provided at the upper and lower ends of the rectangular groove of each X-axis fixing rod 1, and the threaded holes are located on both sides of the U-shaped groove 8 for fixing the Y-axis fixing rod 2. The bottom end of each X-axis fixing rod 1 is fixed with an equal height column 4 by screws, so that the fixing block 10 can slide at the bottom of the X-axis fixing rod 1 or the Y-axis fixing rod 2.

[0025] Specifically, when the jig is needed, first adjust the distance between the two X-axis fixing rods 1 according to the width of the battery top cover 11. When adjusting, turn the fixing screw 3 to release the clamping of the Y-axis fixing rod 2 by the fixing screw 3, and then pull the X-axis fixing rod 1 to move on the Y-axis fixing rod 2 under the action of the rectangular groove to adjust the distance between the two X-axis fixing rods 1. After the adjustment is completed, turn the fixing screw 3 again to re-clamp the fixing screw 3.

[0026] As an optimization solution, Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, each X-axis fixed rod 1 is provided with a plurality of limit mechanism blocks 1 5 on the top surface, and a limit mechanism block 2 6 is provided on the top surface of each X-axis fixed rod 1 between every two limit mechanism blocks 1 5. The width of each limit mechanism block 1 5 and the limit mechanism block 2 6 is greater than the width of the X-axis fixed rod 1, and the width of each limit mechanism block 2 6 is greater than the width of the limit mechanism block 1 5. Each Y-axis fixed rod 2 is provided with a plurality of limit mechanism blocks 3 7, and the length of each limit mechanism block 3 7 is greater than the length of the Y-axis fixed rod 2. A slot that cooperates with the fixing screw 9 is opened inside each limit mechanism block 1 5, the limit mechanism block 2 6 and the limit mechanism block 3 7. A fixing block 10 is provided on the bottom surface of the X-axis fixing rod 1 or the Y-axis fixing rod 2 below the block three 7, each fixing block 10 is configured to be an inverted "T" shape, and the top surface of each fixing block 10 is configured to be an arc shape that matches the end of the U-shaped groove 8. The top surface of each fixing block 10 is embedded in the U-shaped groove 8, and the bottom width of the fixing block 10 is greater than the width of the U-shaped groove 8. A threaded hole that matches the fixing screw 9 is opened on the top surface of each fixing block 10. Each limiting mechanism block one 5, limiting mechanism block two 6 or limiting mechanism block three 7 is fixed to the fixing block 10 through the fixing screw 9 passing through the X-axis fixing rod 1 or the Y-axis fixing rod 2, and a U-shaped groove 8 that matches the fixing screw 9 is opened inside each X-axis fixing rod 1 and the Y-axis fixing rod 2.

[0027] Specifically, when the product widths are different, the limiting mechanism block 1 5 is placed in the U-shaped groove 8 according to the product placement position and then moved to the edge of the product width to support and limit the product on one side. According to the appearance inspection requirements of the battery top cover 11, the distance from both sides of the length of the battery top cover 11 to the center is at least 6mm. When using a two-dimensional measuring instrument, 5mm line segments are required on both sides of the length direction, with a length of 30mm in the middle. When the product lengths are different, the length direction can be adjusted. The limiting mechanism block 3 7 is moved and adjusted in the direction of the Y-axis fixed rod 2 and is symmetrically located on the side of the battery top cover 11. Then, one side of the battery top cover 11 is close to the limiting mechanism block 3 7, and then the limiting mechanism block 2 6 is moved on the X-axis fixed rod 1 so that the limiting mechanism block 2 6 abuts against the side of the battery top cover 11, and the battery top cover 11 can be fixed.
