[0019] A material frame 3 is provided on one side of the outer shell 1. In the present embodiment, the outer shell 1 and the material frame 3 are both rectangular structures. Openings are provided on the left and right sides of the outer shell 1. During detection, material is fed in on one side and discharged on the other side. The material frame 3 is provided with openings at the top and on the side close to the outer shell 1, and its size is larger than that of the outer shell 1. The material frame 3 is movably plugged into one side of the outside of the outer shell 1, and the two sides of the material frame 3 are fixedly connected to the outer shell 1 through a fixing structure 8. The fixing structure 8 includes a threaded rod 801 fixed on the outer side wall of the outer shell 1 close to the side of the material frame 3. The outer side walls on both sides of the material frame 3 are penetrated along the length direction thereof with strip-shaped sliding holes 301 adapted to the threaded rod 801. The threaded rod 801 passes through the strip slide hole 301 and is threadedly connected with a fastening nut 802. By loosening the fastening nut 802, the material frame 3 can be pushed and pulled horizontally. When in use, the material frame 3 can be pulled out to one side. When not in use, the material frame 3 can be stored on the outside of the outer shell 1, which can not only reduce the occupied volume for easy transportation, but also abut against one side of the outer shell 1 to play a dust-proof role. After adjusting the position, the fastening nut 802 can be tightened to fix the material frame 3. Furthermore, in order to keep the detection head 2 level, a supporting foot can be set on the side of the bottom of the outer shell 1 away from the material frame 3, or a supporting foot can be set at the bottom of the outer shell 1 and the material frame 3 to ensure that the outer shell 1 is level.

[0021] Reference Figure 2-3 A material storage trough 4 is arranged inside the material frame 3 for horizontal movement forward and backward through a driving mechanism 6. A plurality of placement slots 402 for placing plates are arranged at equal intervals inside the material storage trough 4 through a plurality of partitions 401. The driving mechanism 6 is used to push the material storage trough 4 horizontally, and sequentially deliver the plates inside the placement slots 402 to a side close to the detection head 2. In this embodiment, the width of the material storage trough 4 is equal to or less than half the width of the material frame 3, and the plates can be sequentially delivered to one side of the reference plane between the transmitting end 201 and the receiving end 202. Before the detection, the staff is required to sequentially place multiple plates to be detected inside the placement slots 402. By setting the placement slots 402, multiple plates can be made independent of each other, so as to avoid mutual friction between the plates when pushing the materials one by one, resulting in wear of the coating and affecting the detection accuracy.

[0022] Reference Figure 4-5The driving mechanism 6 includes a connecting plate 601 fixed on one side of the material storage tank 4, the connecting plate 601 extends to the outside of the material frame 3, and the material frame 3 is penetrated with a through hole for accommodating the sliding of the connecting plate 601 forward and backward. A groove bar 602 is vertically fixed to the top of the connecting plate 601 outside the material frame 3, and a plurality of arc-shaped guide grooves 6021 and strip-shaped driving grooves 6022 are evenly spaced on the groove bar 602. A driving disk 603 is rotatably arranged on the outer wall of the material frame 3 through the rotating driving module 604, and one side of the driving disk 603 is provided with a groove bar 6021 that is rotatable with the arc-shaped guide groove 6021. 021 and a driving rod 6032 that is adapted to the driving groove 6022. The guide block 6031 and the driving rod 6032 are respectively arranged at the two ends of the radial direction of the driving disk 603. When the driving rod 6032 rotates to the inside of the driving groove 6022, the driving groove 602 moves horizontally. By rotating the driving module 604 to drive the driving disk 603 to rotate, the groove 602 and the connecting plate 601 can be continuously transported to one side, and then the storage trough 4 and the plate are continuously transported to one side, and the plate is sent one by one to the side close to the detection head 2.

[0023] In this embodiment, the rotation drive module 604 includes a ring gear 6041 fixed to the outer periphery of the driving disk 603, a gear 6042 meshing with the ring gear 6041, and a motor 6043 driving the gear 6042 to rotate. A dust cover is provided on the outer side of the material frame 3, and the groove 602, the driving disk 603, the ring gear 6041 and the driving gear 6042 are covered inside. The motor 6043 is installed on the outer side of the dust cover, and its output end extends to the inside and is fixed to the gear 6042. When working, the gear 6042 is driven to rotate by the motor 6043, and the gear 6042 is meshed with the ring gear 6041, thereby driving the driving disk 603 to rotate. Furthermore, the rotation drive module 604 can also be set to a pulley mechanism, etc. as needed.

[0024] Reference Figure 1 A pushing mechanism 5 is provided on one side of the outer shell 1 to push the plate delivered to one side of the detection head 2 into between the transmitting end 201 and the receiving end 202. The pushing mechanism 5 includes a pushing plate 501 vertically arranged inside the material frame 3 and a linear driving member 502 driving the pushing plate 501 to move closer to or away from the detection head 2. The linear driving member 502 can be specifically an electric push rod. The linear driving member 502 is installed at the top of the outer shell 1, and the output end of the linear driving member 502 is fixedly connected to the top of the pushing plate 501. Through the extension and retraction of the linear driving member 502, the pushing plate 501 is driven to move closer to or away from one side of the outer shell 1, and the plate placed in the placement slot 402 is pushed between the transmitting end 201 and the receiving end 202. At the same time, the plate after detection can be pushed down to realize automatic discharging.

[0025] Reference Figure 6-7The upper and lower ends of the outer shell 1 are both provided with clamping mechanisms 7 for clamping and fixing the upper and lower ends of the plate. Specifically, the two clamping mechanisms 7 are respectively arranged in the middle of the upper and lower ends of the inner shell 1, and are used to clamp and position the upper and lower ends of the plate to be detected, so that the plate is vertically located between the transmitting end 201 and the receiving end 202. Specifically, the clamping mechanism 7 includes two fixing plates 701 symmetrically fixed on the front and rear sides of the inner shell 1 and C-shaped spring pieces 702 respectively installed on the opposite sides of the fixing plates 701. The C-shaped Mounting parts 7021 fixedly connected to the fixing plate 701 are integrally provided on both sides of the spring clip 702. A channel for accommodating the insertion of the plate is formed between the two C-shaped spring clips 702. The mounting part 7021 is fixedly connected to the fixing plate 701 by bolts. The C-shaped spring clip 702 is a metal spring clip that can undergo a certain elastic deformation. The two C-shaped spring clips 702 clamp and limit the plate. At the same time, a channel with large ends and a small middle is formed between the two C-shaped spring clips 702, which makes it convenient for the plate to be pushed between the two C-shaped spring clips 702. The structure is simple and practical.

[0026] In this embodiment, the material storage trough 4 is rotatably connected to the connecting plate 601 for adjusting the position of the material storage trough 4. The material storage trough 4 can be flipped over. When the material storage trough 4 is flipped over to a horizontal state, its bottom end is not lower than the bottom end inside the outer shell 1. When not in use, the material storage trough 4 is flipped over to a vertical state, and then the material frame 3 can be conveniently pushed to the outside of the outer shell 1 for storage. One end of the material storage trough 4 can also be lifted to insert it into the bottom end inside the outer shell 1.

[0027] Working principle: When working, the material frame 3 is pulled to one side of the outer shell 1, and the threaded rod 801 slides inside the strip slide hole 301. After adjusting the position of the material frame 3, tighten the fastening nut 802 to fix it, and then flip the material storage tank 4 to a horizontal position. During detection, firstly, multiple plates to be detected are placed vertically between each placement slot 402, and the linear drive member 502 pushes the push plate 501 to move to the side close to the detection head 2. The push plate 501 pushes the plate inside the placement slot 402 into between the transmitting end 201 and the receiving end 202. The clamping mechanism 7 clamps and positions the upper and lower ends of the plate, so that the plate is vertically located between the transmitting end 201 and the receiving end 202. After the detection is completed, the rotating drive module 604 drives the drive disk 603 to rotate. When the drive rod 6032 rotates to the inside of the drive slot 6022, it pushes the slot bar 602 to move horizontally to one side, and the material pushing mechanism 5 continues to push the material, and so on. The reciprocating cycle improves the detection efficiency. When not in use, the linear drive member 502 is retracted to retract the push plate 501 to one side of the outer shell 1, and then the material storage trough 4 is flipped vertically and the material frame 3 is pushed to the outside of the outer shell 1 for storage and shielding to reduce occupied space.
