[0051] Specifically, the moving block 141 is a rectangular block slidably connected to the first slide rail 11. A threaded hole is opened above the moving block 141, and a fixing bolt 143 is threaded in the threaded hole. When the moving block 141 slides into place on the first slide rail 11, the moving block 141 is positioned and fixed on the first slide rail 11 by the fixing bolt 143.

[0056] In this embodiment, an external light is provided on the detection camera 12 , and the external light provides better light when the detection camera 12 is shooting, thereby increasing the accuracy of the pictures shot by the detection camera 12 .

[0057] like Figure 4 As shown, in this embodiment, the material pasting mechanism 2 includes a cylinder 21, a placement plate 23 and a pressing plate 22. The placement plate 23 is parallel to the first slide rail 11 and both ends are fixed on the inspection table 6. The cylinder 21 is fixed behind the placement plate 23. One end of the pressing plate 22 is connected to the cylinder 21 and is driven by the cylinder 21 to move the pressing plate 22 closer to or away from the placement plate 23. The pressing plate 22 fixes the material pasted on the placement plate 23.

[0058] A rubber strip 24 is disposed at one end of the pressing plate 22 close to the placing plate 23 . The rubber strip 24 is used to protect the sticker and reduce the possibility of damage to the sticker.

[0059] like Figure 5 As shown, in this embodiment, a clamping mechanism 3 and a lifting mechanism 4 are also included. The clamping mechanism 3 is arranged on the detection table 6 and is located below the material pasting mechanism 2. The clamping mechanism 3 is used to clamp the printing roller. The lifting mechanism 4 is arranged at the bottom of the detection table 6. The clamping mechanism 3 and the lifting mechanism 4 are connected by a screw rod 5. The lifting mechanism 4 controls the clamping mechanism 3 to move closer to or away from the material pasting mechanism 2 through the screw rod 5.

[0060] Specifically, the screw rod 5 is arranged in the vertical direction in the detection platform 6, and both ends of the clamping mechanism 3 are connected to the lifting mechanism 4 through the screw rod 5 respectively. The connection at both ends can maintain the stability of the clamping mechanism 3 when the clamping mechanism 3 moves.

[0061] In this embodiment, the clamping mechanism 3 includes a lifting plate 31, which is located between the placement plate 23 and the lifting mechanism 4 and moves in the vertical direction in the detection table 6. The lifting plate 31 is vertically arranged between the placement plate 23, and internal threaded holes are opened on both sides of the lifting plate 31 along the vertical direction, and the internal threaded holes correspond to the threads on the screw rod 5.

[0062] The threaded hole is threadedly connected to the screw rod 5 , and the screw rod 5 rotates to drive the lifting plate 31 to move, and the rotational motion of the screw rod 5 is converted into the linear motion of the lifting plate 31 .

A positioning block 34 is connected to each slide plate 33, and a V-shaped placement groove 341 is provided on the positioning block 34. Both sides of the printing roller are placed in the V-shaped placement groove 341. The positions of the two slide plates 33 on the second slide rail 32 are adjusted according to the size of the printing roller. The sliding of the slide plate 33 on the slide rail can meet the needs of placing printing rollers of different sizes, thereby increasing the applicability of the clamping mechanism 3.

[0064] Specifically, an end surface of the slide plate 33 away from the lifting plate 31 and the outer side of the placement plate 23 are the same vertical plane.

[0065] The positioning block 34 is fixedly connected to the end surface of the slide plate 33 away from the second slide rail 32. The two positioning blocks 34 are parallel to each other. When the printing roller is placed on the positioning blocks 34, the printing roller is kept parallel to the placement plate 23.

[0066] The two positioning blocks 34 are located on the pressure plate 22. The V-shaped placement groove 341 on the positioning block 34 is opened on the end surface of the positioning block 34 close to the material pasting mechanism 2, so that the two sides of the printing roller are correspondingly placed on the positioning blocks 34 and the printing roller is directly below the pasting material.

[0067] A lifting cylinder 35 is respectively provided on the outer sides of the two positioning blocks 34, and a clamping member 36 is connected to the lifting cylinder 35. The lifting cylinder 35 controls the clamping member 36 to move toward and away from the positioning block 34 in the vertical direction. The clamping member 36 is close to the positioning block 34 to form a positioning clamp for the printing roller on the V-shaped placement groove 341, thereby reducing the risk of the printing roller slipping out of the V-shaped placement groove 341 when the clamping mechanism 3 moves.

[0068] The positioning member is a cylindrical shape, and the positioning member corresponds to the center position of the V-shaped placement groove 341 in the horizontal direction.

The other second gear 412 is located on the inner side of the first gear 411 close to the synchronization rod 41. The first gear 411 and the transmission gear 421 are in the same plane.

[0074] There is a distance between the second gear 412 and the first gear 411 , the second gear 412 and the first gear 411 rotate coaxially, and the number of teeth of the second gear 412 is smaller than that of the first gear 411 . The rotation speed of the motor 42 is fast, and the transmission rotation speed of the second gear 412 is smaller than that of the first gear 411 .

[0075] like Figure 8 As shown, in this embodiment, a third gear 51 is provided at one end of the screw rod 5 away from the lifting plate 31, and the third gear 51 is meshed with the second gear 412.

The synchronization rod 41 and the screw rod 5 are respectively rotatably connected to the two plates of the positioning plate 61. The synchronization rod 41 and the screw rod 5 are perpendicular to each other. The second gear 412 and the third gear 51 are vertically meshed, and the horizontal rotation of the synchronization rod 41 is converted into the vertical rotation of the screw rod 5, driving the lifting plate 31 to move in the vertical direction.

[0079] The implementation principle of the embodiment of the present application is as follows: the initial distance between the two detection cameras 12 is adjusted according to the distance between the cross lines on both sides of the sticker, the sticker is placed on the placement plate 23, the detection camera 12 captures the picture transmitted to the display screen 13 to adjust the placement position of the sticker, so that the cross lines on the sticker are aligned with the standard lines in the display screen 13, the cylinder 21 drives the pressure plate 22 to approach the placement plate 23, fixes the sticker on the placement plate 23, and places the two sides of the printing roller in the V-shaped placement groove 341 accordingly, and the clamping member 36 is moved downward by lifting the cylinder 35 to clamp and fix the printing roller, the motor 42 rotates to drive the synchronization rod 41 to rotate, the second gear 412 and the synchronization rod 41 rotate coaxially, the second gear 412 drives the third gear 51 to rotate so that the screw rod 5 rotates synchronously, and the threaded transmission between the screw rod 5 and the lifting plate 31 enables the lifting plate 31 to drive the printing roller to move close to the sticker, and the printing roller is wound on the printing roller after it is in place.
