[0028] The working principle of the embodiment is as follows: in use, the operator first places the end cover sheet on the bearing disc 403 and in the positioning frame 404; at this time, the initial state of the detection plate 505 is in contact with one of the two limiting rods 509, and after the detection plate 505 is driven to rotate by the second motor 507, the detection plate 505 will be in contact with the other limiting rod 509, and at this time, the rotated detection plate 505 is located directly above the end cover sheet; then, the operator turns on the laser range finder 510, and then starts the first electric push rod 501 to make the detection plate 505 and the laser range finder 510 slide downward until the bottom of the detection plate 505 is in contact with the upper surface of the end cover sheet, at this time, the laser range finder 510 detects the distance between the laser range finder 510 and the base plate 506, and the operator observes and records the data; then, the operator makes the detection plate 505 and the laser range finder 510 slide upward through the first electric push rod 501, and then rotates the bearing disc 403 and the end cover sheet thereon through the first motor 406, and then stops, and the detection plate 505 and the laser range finder 510 slide downward, the laser range finder 510 detects the distance between the laser range finder 510 and the base plate 506, and the operator continues to observe and record the data, and repeats the above operation, the operator obtains multiple data through the detection of the end cover sheet, and analyzes the multiple data, if the measured distance data is small or consistent within the tolerance range, it indicates that the flatness of the end cover sheet is consistent and meets the standard, and the end cover sheet is qualified; if the measured distance data is large and outside the tolerance range, it indicates that the flatness of the end cover sheet is inconsistent and does not meet the standard, and the end cover sheet is unqualified, and thus the flatness detection of the end cover sheet by the gauge is completed. After the end cover sheet is detected, the operator reverses the detection plate 505 by 90 degrees through the second motor 507 to reset the detection assembly 5, and then the operator rotates the rotating column 402, the main body plate 401 and the bearing disc 403 through the third motor 9. At this time, if the end cover sheet is qualified, the bearing assembly 4 rotates clockwise by 90 degrees, and if the end cover sheet is unqualified, the bearing assembly 4 rotates counterclockwise by 90 degrees, so that the qualified end cover sheet and the unqualified end cover sheet can fall on the two sides of the partition plate 10 respectively. At this time, the end cover sheet can be turned to the two sides for overturning, which is to distinguish the qualified and unqualified end cover sheets and to separate them for unloading. Therefore, the end cover sheet needs to be tilted and dropped after detection, and the vibration force of the vibration motor 407 can vibrate the end cover sheet to assist the tilting and unloading of the end cover sheet after detection.

[0029] Embodiment 2 With reference to Figures 7-8 The bottom plate 12 is provided with two storage assemblies 13 above, and each storage assembly 13 comprises a storage box 1301. A plurality of ground wheels 1302 are fixed to the bottom of the storage box 1301 by bolts, and a handle 1303 is fixed to one side of the outer wall of the storage box 1301 by a bolt. The two storage assemblies 13 can separately store the qualified end cover sheets and the unqualified end cover sheets, so as to collect the end cover sheets after detection and facilitate subsequent processing or use of the end cover sheets. A first magnetic block 1304 is attached to one side of the outer wall of the storage box 1301, and a second magnetic block 1305 is attached to each side of the partition plate 10, and the first magnetic block 1304 is attracted to the corresponding second magnetic block 1305.

[0030] The working principle of the embodiment is that when the end cover sheets are unloaded after detection, the two storage assemblies 13 can separately store the qualified end cover sheets and the unqualified end cover sheets, so as to concentrate the end cover sheets after detection and facilitate subsequent processing of the end cover sheets after detection. The combination of the first magnetic block 1304 and the second magnetic block 1305 can position and fix the position of the storage box 1301, so as to align the storage box 1301 with the bearing assembly 4 and facilitate the storage assembly 13 to collect the end cover sheets.
