[0024] Example 1

[0025] Combination Figures 1-5 An automatic product casing detection device includes a first fixing ring 1, a second fixing ring 2 and an industrial camera 10. The first fixing ring 1 and the second fixing ring 2 are fixedly connected by four connecting rods 3, and two support legs 4 are symmetrically installed at the bottom of the first fixing ring 1 and the second fixing ring 2.

[0026] See Figure 1 , Figure 4 and Figure 5 Furthermore, it is found that four connecting structures 11 are slidably connected between the first fixed ring 1 and the second fixed ring 2. Each connecting structure 11 includes a gantry frame 12, which is slidably connected between the first fixed ring 1 and the second fixed ring 2. Slide strips 20 are fixedly installed at the front and rear of the industrial camera 10. A slide groove 13 is opened on the inner side of the gantry frame 12. The industrial camera 10 is slidably connected to the slide groove 13 through the slide strip 20. A screw 14 is rotatably connected inside one of the slide grooves 13, and the screw 14 is threadedly connected to one of the slide strips 20.

[0027] Specifically, the ring structure consists of a first fixed ring 1 and a second fixed ring 2, with four sets of gantry frames 12 installed on the inner side. Each gantry frame 12 can be rotated and adjusted between the first fixed ring 1 and the second fixed ring 2. Moreover, each industrial camera 10 can also be adjusted in position on the inner side of the gantry frame 12 to facilitate adjustments for the product position. Furthermore, the four industrial cameras 10 can capture and inspect the product housing from the top, bottom, left, and right. The industrial camera 10 adopts the "industrial camera 2" disclosed in publication number CN219369594U.

[0028] Example 2

[0029] See Figure 2 Furthermore, based on Embodiment 1, the opposite surfaces of the first fixing ring 1 and the second fixing ring 2 are provided with ring grooves. The front and rear parts of the gantry frame 12 are fixedly connected with arc strips that match the ring grooves. The front part of the gantry frame 12 is fixedly installed with a locking block 15. The front part of the locking block 15 is threadedly connected with a second bolt 21. The second bolt 21 passes through the locking block 15 and presses against the front part of the second fixing ring 2.

[0030] Specifically, once the position of the gantry frame 12 is adjusted to the appropriate position, the second bolt 21 is rotated, and the second bolt 21 can be pressed against the front of the second fixing ring 2, thereby locking the position of the second fixing ring 2.

[0031] Example 3

[0032] See Figure 3Furthermore, based on Embodiment 1 and Embodiment 2, a guide structure 5 is provided between the four connecting rods 3. The guide structure 5 includes four support rods 6, which are respectively fixedly installed on the outside of the four connecting rods 3. A fixed sleeve 7 is fixedly installed between two support rods 6 aligned in the vertical direction. A transparent plate 8 is rotatably connected between the two fixed sleeves 7. Rollers 9 are rotatably connected to both ends of the transparent plate 8. An adjustment structure is provided between the transparent plate 8 and the fixed sleeve 7. The adjustment structure includes a connecting shaft 16 and a first bolt 18. The connecting shaft 16 is fixedly installed at the center of the side of the transparent plate 8. The first bolt 18 is threadedly connected to the center of one side of the fixed sleeve 7. A gear 17 is fixedly connected to one end of the connecting shaft 16 inside the fixed sleeve 7. A gear sleeve 19 is rotatably connected to one end of the first bolt 18 inside the fixed sleeve 7. The gear 17 and the gear sleeve 19 are meshed. The contact surface between the gear sleeve 19 and the fixed sleeve 7 is hexagonal.

[0033] Specifically, a suitable space is reserved between the first conveyor belt 22 and the second conveyor belt 23, which have a height difference. The entire device is then set between the first conveyor belt 22 and the second conveyor belt 23. The first bolt 18 is rotated to move the gear sleeve 19, causing the gear sleeve 19 to separate from the gear 17. After separation, the tilt angle of the transparent plate 8 can be adjusted to match the height difference between the first conveyor belt 22 and the second conveyor belt 23. Then, the first bolt 18 is rotated again to put the gear sleeve 19 on the outside of the gear 17, thus locking the position of the transparent plate 8. When the shell product falls onto the upper part of the transparent plate 8 after passing the first conveyor belt 22, the industrial camera 10 takes pictures of the product shell from the top, bottom, left, and right. The tilted transparent plate 8 guides the product shell to the second conveyor belt 23 for continued conveying.

[0034] It should be noted that this utility model is an automatic product casing detection device. In use, the entire device is set between the first conveyor belt 22 and the second conveyor belt 23, which have a height difference, via the support leg 4. Rotating the first bolt 18 moves the gear sleeve 19, causing the gear sleeve 19 to separate from the gear 17. After separation, the tilt angle of the transparent plate 8 can be adjusted to adapt to the height difference between the first conveyor belt 22 and the second conveyor belt 23. Then, rotating the first bolt 18 again puts the gear sleeve 19 over the gear 17, thus locking the position of the transparent plate 8 and simultaneously making the rotating roller 9 contact the conveyor belt. To ensure that the rotation of the two conveyor belts is not affected, the position of each gantry 12 is adjusted. After adjustment, the second bolt 21 is tightened for fixation. Then, the screw 14 is rotated, and the screw 14 drives the industrial camera 10 to move through the slide bar 20. The positions of the four industrial cameras 10 are adjusted. When the product shell is sent to the upper part of the transparent plate 8 through the first conveyor belt 22, the four industrial cameras 10 take pictures and detect the upper, lower, left and right of the product shell. Then, the product shell is guided by the transparent plate 8 or pushed into the upper part of the second conveyor belt 23 for continued conveying, completing the entire product shell shooting and detection work.
