[0026] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Example

[0028] like Figure 1 and Figure 7 As shown, the utility model proposes a uniform silicone coating quality detection device for self-adhesive labels, including a chassis 1 and a top cover 2 installed on the chassis 1, two support blocks 201 are fixedly installed on both sides of the chassis 1, and slide columns 202 are slidably installed on the support blocks 201, and two connecting blocks 203 are fixedly installed on both sides of the top cover 2, and the slide columns 202 correspond to the connecting blocks 203 one by one and are fixedly connected, and limiting components are installed on both sides of the chassis 1, and the limiting components limit whether the slide columns 202 can slide.

[0029] Among them, the limiting assembly includes a limiting cylinder 204 fixedly installed on the support block 201, a limiting column 205 slidably installed in the limiting cylinder 204, a pull rod 207 fixedly installed on the limiting column 205, a connecting plate 208 fixedly installed on the two pull rods 207 on the same side, a handle 209 fixedly installed on the connecting plate 208, and a limiting hole 210 provided on the sliding column 202. The limiting column 205 passes through one side of the support block 201 and rests on the sliding column 202 under the action of the spring 206. Pulling the top cover 2 upwards can drive the connecting block 203 to rise, thereby driving the sliding column 202 to move upward. When the limiting hole 210 moves to a coaxial position with the limiting column 205, the limiting column 205 will enter the limiting hole 210 under the action of the spring 206, thereby limiting the sliding column 202 and preventing the sliding column 202 from falling under the action of gravity. When the top cover 2 is combined with the chassis 1, pulling the handle 209 drives the connecting plate 208 to move, thereby driving the pull rod 207 to move, and pulling the limiting column 205 out of the limiting hole 210 can make the top cover 2 fit with the chassis 1.

[0030] like Figure 2 and Figure 6As shown, it also includes a traction assembly, which supports the label and transfers the label at the same time. The traction assembly includes two groups of support rods 5 fixedly installed in the chassis 1, two transmission rollers 501 rotatably installed on the same group of support rods 5, gears 502 fixedly installed on the two transmission rollers 501, transmission belts 503 fixedly installed on the two groups of gears 502, and a fourth motor 504 fixedly installed on one group of support rods 5, the output shaft of the fourth motor 504 is fixedly connected to one of the transmission rollers 501, and the two gears 502 located on the same group of support rods 5 are meshed with each other. After the top cover 2 is separated from the chassis 1, the label can be placed between the transmission rollers 501 on the upper and lower sides. After the placement is completed, the top cover 2 can be attached to the chassis 1, and then the fourth motor 504 is started to drive one of the transmission rollers 501 to rotate. Through the transmission of the gears 502 and the transmission belt 503, the two transmission rollers 501 on the two sides can be rotated synchronously, and the two transmission rollers 501 on the same side turn in opposite directions, which can drive the label to move.

[0031] like Figure 1-4 As shown, the detector 3 is fixedly mounted on the top cover 2, and also includes a centering component installed in the top cover 2, and the centering component adjusts the labels of different specifications to move to just below the middle of the monitor. The centering component includes two groups of support seats 6 fixedly mounted on the top cover 2, a first bidirectional screw 605 rotatably mounted on the same group of support seats 6, a driving block 601 threadedly connected to both sides of the first bidirectional screw 605, and an adjustment block 602 fixedly mounted on the driving block 601, and the angle between the two adjustment blocks 602 located below the same group of support seats 6 is an acute angle. When the top cover 2 is combined with the chassis 1, the top cover 2 moves in a direction close to the chassis 1, thereby driving the adjustment block 602 to move, so that the adjustment block 602 can contact the label, and exert a lateral force on the label, so that the label can move to the middle position, so that the label can move to just below the detector 3;

[0032] It also includes a driving assembly for driving two first bidirectional screws 605 to rotate synchronously, and the driving assembly includes a first motor 604 fixedly mounted on one of the support seats 6, and a linkage belt 603 fixedly mounted on the two first bidirectional screws 605, and the output shaft of the first motor 604 is fixedly connected to one of the first bidirectional screws 605. When detecting labels of different specifications, the distance between the two adjustment blocks 602 located on the same side is adjusted according to the width of the different labels. When adjusting, the first motor 604 is started to drive one of the first bidirectional screws 605 to rotate, and the two first bidirectional screws 605 can be rotated synchronously through the linkage belt 603, so that the distance between the two adjustment blocks 602 on both sides can be adjusted, and labels of different widths can be guided.

[0033] like Figure 2-3 and Figure 5 As shown, an illumination device 301 is fixedly installed in the chassis 1 and is located directly below the detector 3, and an irradiation range adjustment component is installed in the chassis 1 and is located above the irradiation range adjustment component. A box body 302 is fixedly installed in the chassis 1, and the irradiation range adjustment component includes two first adjustment plates 4 slidably installed on the box body 302, a first connecting block 402 fixedly installed on the first adjustment plate 4, a second adjustment plate 401 slidably installed on the first adjustment plate 4, a second connecting block 405 fixedly installed on the second adjustment plate 401, a second bidirectional screw rod 403 rotatably installed in the chassis 1 and threadedly connected to the two first connecting blocks 402, a third bidirectional screw rod 406 rotatably installed in the chassis 1 and threadedly connected to the two second connecting blocks 405, a second motor 404 fixedly installed in the chassis 1 and fixedly connected to the second bidirectional screw rod 403, and a third motor 407 fixedly installed in the chassis 1 and fixedly connected to the third bidirectional screw rod 406. The lighting device 301 will provide light sources, which will illuminate the labels. The illumination area of ​​the light sources can be adjusted according to the gears of different labels so that the light sources can be accurately illuminated on the labels to prevent the light sources from scattering around and reducing the detection accuracy of the detector. When making adjustments, the second motor 404 is started to drive the second bidirectional screw rod 403 to rotate, so that the two first adjustment plates 4 can be moved closer to or farther away from each other, so that the distance between the two first adjustment plates 4 can be kept consistent with the length of the label. Starting the third motor 407 can drive the third bidirectional screw rod 406 to rotate, so that the two second adjustment plates 401 can be moved closer to or farther away from each other, so that the distance between the two second adjustment plates 401 can be kept consistent with the width of the label, so that the range of the light source outlet can be changed, so that the light source can be accurately illuminated on the label.

[0034] Working principle: Pulling the top cover 2 upwards can drive the connecting block 203 to rise, thereby driving the sliding column 202 to move upwards. When the limiting hole 210 moves to a coaxial position with the limiting column 205, the limiting column 205 will enter the limiting hole 210 under the action of the spring 206, thereby limiting the sliding column 202, and putting the label between the upper and lower transmission rollers 501. After the placement is completed, pull the handle 209 to drive the connecting plate 208 to move, thereby driving the pull rod 207 to move, and pull the limiting column 205 out of the limiting hole 210 to make the top cover 2 fit with the chassis 1.

[0035] When the top cover 2 is combined with the chassis 1, the top cover 2 moves toward the chassis 1, thereby driving the adjustment block 602 to move, so that the adjustment block 602 can contact the label and exert a lateral force on the label, so that the label can move to the middle position, so that the label can move to the bottom of the detector 3. When detecting labels of different specifications, the first motor 604 is started, and the two first bidirectional screws 605 can be rotated synchronously through the linkage belt 603, so that the distance between the two adjustment blocks 602 on both sides can be adjusted, so that labels of different widths can be guided;

[0036] Then the fourth motor 504 is started to drive the two transmission rollers 501 on both sides to rotate synchronously, so as to drive the label to move;

[0037] The lighting device 301 illuminates the label with a light source, and the illumination area of ​​the light source can be adjusted according to the gears of different labels. The second motor 404 is started to drive the second bidirectional screw 403 to rotate, so that the two first adjustment plates 4 can be moved closer or farther away from each other, so that the distance between the two first adjustment plates 4 can be kept consistent with the length of the label. The third motor 407 is started to drive the third bidirectional screw 406 to rotate, so that the two second adjustment plates 401 can be moved closer or farther away from each other, so that the distance between the two second adjustment plates 401 can be kept consistent with the width of the label, so that the range of the light source outlet can be changed, and the light source can be accurately illuminated on the label. The light source can be accurately illuminated on the label to prevent the light source from scattering everywhere and reducing the detection accuracy of the detector.
