[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To address the limitations of existing inspection methods, whether manual or traditional equipment-based, in meeting the demands of high-volume production and lacking comprehensive inspection accuracy, please refer to [link to relevant documentation]. Figures 1-7 The following technical solutions are provided:

[0026] This utility model discloses a magnetic tile size detector, comprising a platform 1, on which a conveyor belt 11, a lifting detection platform 12, and a feeding belt 13 are arranged from left to right. The feeding belt 13 is provided with multiple equally spaced partitions 14 to increase the functionality of the platform 1, complete the feeding detection, size detection, and sorting and unloading of the magnetic tiles through the partitions 14. A detection frame 2 is provided on one side of the platform 1, and a detector 3 is installed on the upper end of the detection frame 2. The detector 3 on the detection frame 2 performs size detection on the magnetic tiles. A turntable 121 is provided at the bottom of the lifting detection platform 12. An electric cylinder is provided inside the platform 1. The lifting detection platform 12 is connected to the electric cylinder through the turntable 121. The turntable 121 can control the rotation of the lifting detection platform 12, and change the angle of the magnetic tile detection size in conjunction with the gripping assembly. The electric cylinder can change the height of the lifting detection platform 12.

[0027] The upper end of platform 1 is equipped with symmetrical pusher plates 4 that can be offset left and right. A groove 15 is provided on the upper surface of platform 1 for moving the pusher plates 4. The pusher plates 4 can push the magnetic tiles fed by the conveyor belt 11 onto the lifting detection platform 12, close to the gripper assembly for convenient control of dimensional detection. Upon completion of detection, the magnetic tiles can be fed into the feeding belt 13 for delivery. A wire rod 151 is provided inside the groove 15. A slider 41 is connected to the lower end of the pusher plates 4 via the groove 15. A roller 42 for driving the pusher plates 4 is provided at the upper end of the slider 41, and teeth 43 that mesh with the roller 42 are provided at the lower end of the pusher plates 4. Figure 7 Visually, the distance between the two pusher plates 4 can be achieved by the rolling between the roller 42 and the toothed 43 to achieve the effect of movement. The distance between the two pusher plates 4 is brought closer to facilitate dragging and pushing forward from the back of the magnetic tile until the size detection is completed.

[0028] The front end of the support rod 5 is movably connected to a gripping assembly for holding the magnetic tile. The gripping assembly includes a clamping base 6, four limiting strips 61, and four clamping rods 62. The four clamping rods 62 can clamp the magnetic tile from four directions. This addresses the instability of clamping from only the sides, as clamping from only the sides would inevitably result in excessive clamping force, potentially causing unnecessary damage to the surface of the magnetic tile. Each of the four clamping rods 62 has a buffer pad 621 on its inner side to cushion the clamping force. A rotating rod 63 connects the four limiting strips 61 to the clamping base 6, allowing the limiting strips 61 to be rotated backward to open them, thus allowing the magnetic tile to be clamped. When clamping, the clamping of the magnetic tile is released from both sides. The buffer pads 621 are all set inside the limiting strips 61 to avoid excessive clamping and damage to the surface of the magnetic tile during the clamping process. The front surface of the limiting strips 61 is provided with a sliding groove 611. The sliding groove 611 is provided with a telescopic rod 612 for controlling the displacement of the clamping rod 62. The telescopic rod 612 drives the clamping rod 62 to adjust the distance according to the width and height of the magnetic tile along the sliding groove 611. The clamping rod 62 is connected to the telescopic rod 612 through the sliding groove 611. A buffer spring is provided between the clamping rod 62 and the buffer pad 621.

[0029] Platform 1 has a support rod 5 at its upper end. The front end of the support rod 5 has a telescopic rod 51 that can be raised and lowered to control the height of the clamping seat 6. The front end of the telescopic rod 51 has a turntable 52 for driving the clamping seat 6 to rotate. This controls the rotation angle of the four clamping rods 62 to change the angle of the magnetic tile during measurement, ensuring measurement accuracy. The front end of the turntable 52 is fixedly connected to a connecting rod 53 for connecting the clamping seat 6. The front surface of the support rod 5 has a sliding groove 54. An electric cylinder is installed in the sliding groove 54, and the telescopic rod 51 is connected to the sliding groove 54 through the electric cylinder. The electric cylinder can control the height of the clamping seat 6 to move up and down, improving the flexibility of clamping the magnetic tile.

[0030] Working principle: The magnetic tile to be inspected is placed on the conveyor belt 11, which then transports it to the inspection area. At this point, the pusher plates 4 on both sides engage with the rollers 42 on the slider 41 and the teeth 43 at the bottom of the pusher plates 4, causing them to move closer together until they are at the rear end of the magnetic tile. This moves the magnetic tile forward onto the lifting inspection platform 12. The lifting inspection platform 12 then lifts the magnetic tile upwards using an electric cylinder at its bottom. The clamping assembly, clamp 6, first moves upwards according to the height of the magnetic tile, and then uses the telescopic rod 51 to bring the four clamping rods 62 closer to the magnetic tile. The position of the magnetic tile on the lifting inspection platform 12 can be adjusted by moving the clamping rods 62 on the left and right sides inwards. Meanwhile, the positions of the magnetic tiles on the upper and lower sides are adjusted by the clamping rods 62. Before adjusting the position of the magnetic tile, the clamping rod 62 is folded backward based on the rotating rod 63, so that it will not affect the adjustment of the magnetic tile. Then the detector 3 can measure the size of the current magnetic tile. If it is necessary to adjust the front or back or side position of the magnetic tile, the clamping rods 62 located on the top and bottom and left and right sides of the magnetic tile clamp from the bottom and surface and the two sides of the magnetic tile, respectively. Then the turntable 52 drives the clamping seat 6 to rotate to the appropriate position according to the actual measurement requirements. At the same time, the lifting detection table 12 rotates the magnetic tile angle, and then the magnetic tile is released to start the size measurement. After the measurement is completed, the rotating rod 63 releases the magnetic tile, the lifting detection table 12 drives the magnetic tile back to the platform 1, and the pusher plate 4 sends the tested magnetic tile to the feeding belt 13 for delivery along the slide groove 15.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
