The positioning mechanism 300 is located at the press-fitting station 200 and comprises a workpiece detection assembly 310 for detecting the position of the workpiece to be press-fitted, a clamping assembly 320 and a limiting assembly 330. The clamping assembly 320 comprises two first clamping members 321 which move relatively along a first direction. Each first clamping member 321 is provided with at least two second clamping members 322 which move relatively along a second direction. The second clamping members 322 are located on the side of the first clamping member 321 close to the workpiece to be press-fitted. The limiting assembly 330 is arranged on the side of the press-fitting station 200 away from the press-fitting mechanism 400 and moves along a third direction. The first direction, the second direction and the third direction are arranged at an included angle respectively.

[0030] In the present embodiment, the press-fitting station 200 is arranged on the rack 100. The workpiece to be press-fitted is conveyed to the press-fitting station 200 by a conveying jig and then conveyed to the next process after the press-fitting is completed. Specifically, after the workpiece detection assembly 310 detects that the conveying jig conveys the workpiece to be press-fitted to the press-fitting station 200, the limiting assembly 330 is started to move along the third direction to the preset position close to the press-fitting station 200 to limit the movement of the conveying jig in the direction opposite to the press-fitting direction of the press-fitting mechanism 400.

Finally, the press-fitting mechanism 400 is started to move downward toward the press-fitting station 200 by the press block 410 to perform the press-fitting operation on the workpiece to be press-fitted. The four directions of the workpiece to be press-fitted are clamped and positioned by the clamping assembly 320, i.e. the clamping and positioning of the workpiece to be press-fitted in the first direction and the second direction are realized, and the limiting protection of the workpiece to be press-fitted in the third direction is realized by the limiting assembly 330, so as to ensure the accurate positioning of the workpiece to be press-fitted and keep the clamping and fixing of the workpiece to be press-fitted, thereby avoiding the deviation of the workpiece to be press-fitted during the press-fitting process and ensuring the accuracy of the press-fitting operation.

[0031] In the embodiment, the workpiece to be pressed is a battery. In actual operation, the device is often used for the pressing operation of the square battery, so that the clamping assembly 320 clamps and positions the square battery from the four sides of the square battery, which can effectively ensure the accuracy of the positioning of the square battery. In actual operation, the side with the largest area of the square battery is the large side, and the two large sides of the square battery are respectively arranged towards the first clamping jig on the two sides, which facilitates the pre-positioning and clamping effect of the first clamping jig on the square battery, so that when the second clamping jigs on the two sides approach each other towards the first clamping jig, the two other sides of the square battery can be smoothly clamped and positioned, ensuring the accuracy of the clamping of the clamping assembly 320 on the square battery and avoiding the situation of clamping failure or clamping failure. In actual operation, the first direction, the second direction and the third direction are arranged perpendicular to each other.

Specifically, through the driving of the first driving member 323, the sliding plate 327 slides on the mounting plate 326, thereby driving the first clamping member 321 and the second clamping member 322 arranged on the sliding plate 327 to move, so that the first clamping member 321 and the second clamping member 322 can move to the pressing station 200 and clamp and position the square battery.

Specifically, the two second clamping members 322 on the movement module 325 are driven by the second driving member 324 to move relatively along the second direction, thereby realizing the clamping or loosening operation of the square battery.

[0034] In one of the embodiments, the first clamping piece 321 and the second clamping piece 322 are provided with a flexible protective pad 328 on the side surface abutting the workpiece to be pressed, which can effectively prevent the side surface of the square battery from being deformed by extrusion. In actual operation, the flexible protective pad 328 can be a sponge pad, a rubber pad, etc., which can effectively achieve the protection effect of the square battery. Moreover, the flexible structure can also increase the friction force with the surface of the square battery, thereby improving the clamping degree of the first clamping piece 321 and the second clamping piece 322 on the square battery. Further, the side surface of the flexible protective pad 328 abutting the square battery is provided with anti-skid lines (not shown), so as to further improve the friction force between the flexible protective pad 328 and the square battery, and improve the clamping degree on the square battery.

Among them, the clamping assembly 320 is arranged on the top of the support frame 110, and the first clamping piece 321 and the second clamping piece 322 are arranged on the side facing the pressing station 200. The two limiting assemblies 330 are arranged on the side of the two support frames 110 facing the pressing station 200, so that the limiting support 331 can limit the workpiece to be pressed.

[0037] In one of the embodiments, the workpiece detection assembly 310 comprises a first sensor 311 for detecting the position of the conveying jig, and a second sensor 312 for detecting the position of the workpiece to be pressed on the conveying jig, the first sensor 311 is provided in two groups, and the two groups of first sensors 311 are respectively arranged on the two sides of the pressing station 200 along the second direction. Specifically, the two groups of first sensors 311 are arranged on the two sides of the clamping assembly 320, i.e. on the two sides of the pressing station 200, so that the entry of the conveying jig into the working range of the pressing station 200 can be effectively detected. When the first sensor 311 detects the conveying jig, the limiting assembly 330 is started, and the limiting frame is raised to a preset height to prevent the conveying jig and the square battery from being pressed downward beyond a certain range during the pressing operation, which may cause the pressing to be out of position.

[0038] The second sensor 312 is arranged between the two groups of first sensors 311 to detect the workpiece to be pressed, i.e. the square battery, on the conveying jig. When the second sensor 312 detects the position information of the square battery, it is determined that the square battery is located in the clamping range of the clamping assembly 320, and the clamping assembly 320 is started to clamp and position the square battery, thereby ensuring the accuracy of clamping and positioning.
