[0024] The frame 4 can be used to reinforce the bottom support of the linear guide rail 12, and at the same time, the stability of the detection plate 5 during installation and use can be improved. The calibration cylinder 10 is embedded in the detection plate 5, and the detection plate 5 can be used to reinforce the installation of the calibration cylinder 10. The calibration cylinder 10 can control the movement of the calibration frame 8, thereby realizing the distance adjustment between the calibration frame 8 and the material tray, so that the calibration frame 8 can be used to push the material tray to move above the conveying roller 3, change the position of the material tray, and then realize the position calibration of the material tray. The infrared ranging sensor 9 can monitor the distance change between the material tray and the detection plate 5 in real time, so as to assist in judging whether there is a position offset after the material tray is unloaded from above the conveying roller 3, thereby improving the accuracy of subsequent material tray centering. Embodiment 2

[0025] like Figure 1-Figure 5As shown, the top of the frame 4 is fixedly connected with an auxiliary part 17, the top of the auxiliary part 17 is rotatably connected with a sprocket 7, the outer ring surface of the sprocket 7 is meshed with a chain 13, one guide plate 11 is fixedly connected with a second connector 16 at the bottom, one side of the second connector 16 is fixedly connected to the chain 13, the bottom of the other guide plate 11 is fixedly connected with a connector 15, one side of the connector 15 is fixedly connected to the chain 13, the bottom of the connector 15 is fixedly connected with an extension part 19, one side of the extension part 19 is fixedly connected with a clamping cylinder 14, one end of the clamping cylinder 14 is fixedly connected to the frame 4. One side of the frame 4 is fixedly connected with a reinforcement frame 6, the top of the reinforcement frame 6 is fixedly connected with a support member 2, the bottom of the support member 2 overlaps the frame 4, and one side of the support member 2 is rotatably connected with a conveying roller 3.

[0026] The auxiliary part 17 can be used to support the bottom of the sprocket 7, so that the sprocket 7 can rotate stably under the drive of the chain 13. The two sides of the chain 13 are connected to the two guide plates 11 through the connecting piece 15 and the connecting piece 2 16 respectively. Therefore, when the chain 13 moves, the two guide plates 11 can be driven to move simultaneously, thereby controlling the two guide plates 11 to move closer to or farther away from each other. The bottom of the guide plate 11 is slidably connected to the linear guide rail 12, and the linear guide rail 12 can be used to guide the guide plate 11 when it moves, thereby improving the stability of the guide plate 11 when it moves.

[0027] The use method and working principle of this device are as follows: First, a driving structure is installed on one side of the support member 2, which can drive multiple conveyor rollers 3 to rotate. When the entire mechanism is used, the material tray is placed above the conveyor roller 3, and the conveyor roller 3 rotates to drive the material tray to move, and the material tray is moved between the two clamping claws 1. At this time, the conveyor roller 3 stops rotating, and the infrared ranging sensor 9 on one side of the detection plate 5 is used to detect the distance between the material tray and the detection plate 5. If the distance is less than the predetermined value, the calibration cylinder 10 is used to drive the calibration frame 8 to move to the side close to the material tray, pushing the material tray away from the detection plate 5 until the detection plate 5 and the material tray is within a predetermined range, at this time, the clamping cylinder 14 is contracted to drive the extension member 19 and the connecting member 15 to move, the connecting member 15 drives the chain 13 to move, drives the sprocket 7 to rotate, and then drives the chain 13 on the other side to move, so that the chain 13 drives the connecting member 2 16 to move, so that the two clamping jaws 1 are moved to the side close to the material tray, so as to achieve the centering clamping of the material tray. After the clamping is completed, the clamping cylinder 14 is extended, the connecting member 15 and the connecting member 2 16 move in the opposite direction, the distance between the two clamping jaws 1 is increased, and the separation from the material tray can be achieved.
