Since the first driving mechanism 20 is disposed in the horizontal direction as a whole, the contact area of the first driving mechanism 20 with the frame 10 can be increased, so that the measuring mechanism 30 moves more smoothly under the driving of the first driving mechanism 20. Moreover, when the second driving mechanism 20 drives the measuring mechanism 30 to move in the vertical direction, the position of the center of gravity of the measuring mechanism 30 is kept constant in the X-axis direction, so that the movement of the measuring mechanism 30 is more stable.

The fine adjustment unit 34 is used to adjust the position of the measurement unit 32 connected thereto in the Z-axis direction, thereby adjusting the relative positions of the two measurement units 32 in the Z-axis direction so that the two measurement units 32 are located at the same position in the Z-axis direction. In this way, the two measurement units 32 can simultaneously measure the unevenness of the first surface to be measured 220 and the second surface to be measured 240 at the same position in the Z-axis direction, and the thickness of the battery 200 at this position in the Y-axis direction can be obtained. Of course, in other embodiments, two fine adjustment portions 34 may be provided, and both of the measurement portions 32 are connected to the mounting portion 40 through the fine adjustment portions 34, so that the positions of the two measurement portions 32 in the Z-axis direction are adjusted through the fine adjustment portions 34.

When the two positioning portions 54 move toward each other, the first guide surface 5421 and the second guide surface 5425 contact the battery 200 first, and since the first guide surface 5421 and the second guide surface 5425 are both inclined in the direction perpendicular to the second positioning surface 5423 and away from the axis of the positioning groove 542, if the position of the battery 200 is shifted, when the two positioning portions 54 continue to move toward each other, the battery 200 can move in the Y-axis direction under the action of the first guide surface 5421 and the second guide surface 5425 until the battery 200 is centered between the first guide surface 5421 and the second guide surface 5425. When the positioning portion 54 moves to the position where the second positioning surface 5423 abuts against the side surface of the battery 200, the positioning portion 54 does not move any more, and the two ends of the battery 200 are located in the positioning grooves 542 of the two positioning portions 54, respectively. The first positioning surface 5422 and the third positioning surface 5424 restrict movement of the battery 200 in the Y-axis direction, and the third positioning surface 5424 restricts movement of the battery 200 in the X-axis direction.

If the sensor 61 detects that the battery 200 is placed between the two positioning mechanisms 50, the battery measuring device 100 can start to measure the flatness of the side surface to be measured when the start switch is started. If the sensor 61 does not detect that the battery 200 is placed between the two positioning mechanisms 50, the battery measuring device 100 does not start to work even if the starting switch is started, so that the battery measuring device 100 is prevented from being accidentally started to hurt workers.

It should be noted that in the present embodiment, the sensor 61 is connected to the frame 10 through the bracket 62, and the frame 10 is provided with a long hole 621 having a circular ring structure.

At this time, the code scanning gun 74 corresponds to the graphic code of the battery 200 and transmits the information of the battery 200 to the controller. Meanwhile, the measuring part 32 corresponds to the position to be measured on the first surface 220 and the second surface 240, and the first driving part 22 and the second driving part 24 continue to drive the mounting part 40 to move, so as to change the position to be measured by the measuring part 32.

Specifically, the first surface-to-be-measured 220 is measured by the measuring unit 32. Referring mainly to fig. 5, under the driving of the first driving portion 22 and the second driving portion 24, the measuring portion 32 first sequentially moves to the positions corresponding to the corners of the first surface to be measured 220, for example, the positions with the distances between two adjacent sides of the first surface to be measured 220 being 5mm, measures the distances between the four reference points 201 and the measuring portion 32 in the Z direction, and then establishes the reference plane with the four reference points 201. For ease of illustration, the four reference points 201 are shown in the figures as hatched dots. Then, the first driving unit 22 and the second driving unit 24 continue to drive the measuring unit 32 to move, and nine measuring points 202 are selected for measurement, for example, nine intersections of bisectors of 1/4, 1/2, and 3/4 of the dimension of the first surface to be measured 220 along the X axis and the Z axis are taken as the measuring points 202, and the nine measuring points 202 are shown by black dots in the figure for convenience of illustration.
