Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of label visual detection, and particularly relates to a visual detection device for a daily chemical product label production system. BACKGROUND

[0002] A daily chemical product label is an important identification attached to product packaging, and its main functions include information transmission, brand promotion, compliance, and user experience optimization. The daily chemical product label production process includes raw material pretreatment, character printing, die cutting, and quality detection. The label quality detection generally needs to identify the characters on the label through a visual detection device to identify character breaks, ghosting, dirty spots, and color difference exceeding the standard.

[0003] In actual identification operations, wrinkles on the label paper can cause the visual detection equipment to be distorted when capturing images, thereby affecting the accuracy of defect identification. Based on this, the prior art uses a pressing plate to press the wrinkles on the label paper flat, such as the patent with publication number CN119269402A. However, pressing the label paper can further cause the characters on the label paper to overlap, thereby increasing the difficulty of visual identification and easily causing identification deviation or identification errors.

[0007] As further optimization or improvement of the scheme, a guide rod is mounted on the top of the driven rack and is in vertical sliding fit with the sliding groove on the platform.

[0008] As further optimization or improvement of the scheme, the anti-warping edge assembly comprises a pressing edge table which is transversely and slidingly mounted in the platform, and a support rod is mounted on the top of the negative pressure disc and is connected to the pressing edge table through a connecting rod; when the negative pressure disc moves upward, the negative pressure disc drives the pressing edge table to move in the direction close to the negative pressure disc through the support rod and the connecting rod.

Specifically, a guide groove 603 is provided in the base 601, and a strip guide block 604 is installed on the top of the display platform 602, and the strip guide block 604 slides with the guide groove 603. Specifically, a guide rod 615 is installed on the top of the driven rack 614, and the guide rod 615 slides vertically with the slide groove on the display platform 602.

[0027] It should be noted that a strip-shaped chute 611 is provided inside the display platform 602, and the insertion rod 610 slides inside the strip-shaped chute 611. The negative pressure plate 616 is connected to a negative pressure device, and pressure is supplied to the negative pressure plate 616 by the negative pressure device.

[0028] Before testing, the label roll to be tested is mounted on the unwinding roller 3 , and then the label tape 5 on the label roll is flattened and connected to the receiving roller 4 .

[0029] During the detection process, the unwinding roller 3 and the receiving roller 4 drive the label strip 5 to pass through the visual detection component 7, which detects and identifies the characters on the label strip 502, and then detects whether the label strip 502 is broken.

[0030] If the label strip 502 on the substrate 501 appears to be wrinkled, when the label strip 502 moves to the bottom of the material pressing assembly 6, the material feeding roller 3 and the material collecting roller 4 stop, and the electromagnetic suction disc 10 is powered to attract the magnetic suction strip 606, at this time, the magnetic suction strips 606 at both ends of the unfolding platform 602 press the substrate 501 through the gap between the label strips 502, and the negative pressure disc 616 adheres to the two side edges of the label strip 502, and the negative pressure disc 616 attracts the two side edges of the label strip 502 through negative pressure; the air cylinder 607 is started, the air cylinder 607 drives the push block 608 to move downward, the push block 608 rolls the label strip 502 from the center to the two sides through the bottom pressing roller 609, at the same time, the push block 608 drives the driving rack 612 to move synchronously through the connecting rod 610, and the push block 608 drives the driven rack 614 and the negative pressure disc 616 to move upward through the transmission relationship of the driving rack 612, the gear 613 and the driven rack 614, and the two side edges of the label strip 502 are lifted by the negative pressure disc 616, so that the height difference between the center and the two sides of the label strip 502 gradually increases, and the label strip 502 is rolled by the pressing roller 609, so that the wrinkles on the label strip 502 are unfolded; as the push block 608 continues to move, the pressing roller 609 presses the unfolded label strip 502 on the substrate 501 again, so that the label strip 502 adheres to the substrate 501, thereby effectively avoiding the overlapping of characters on the label strip 502 and reducing the identification difficulty of the visual detection assembly 7. Figure 9 As the push block 608 moves, the two side edges of the label strip 502 are lifted by the negative pressure disc 616, so that the height difference between the center and the two sides of the label strip 502 gradually increases, and the label strip 502 is rolled by the pressing roller 609, so that the wrinkles on the label strip 502 are unfolded; as the push block 608 continues to move, the pressing roller 609 presses the unfolded label strip 502 on the substrate 501 again, so that the label strip 502 adheres to the substrate 501, thereby effectively avoiding the overlapping of characters on the label strip 502 and reducing the identification difficulty of the visual detection assembly 7.

[0031] It should be noted that the working environment of the present application is a dust-free environment.

[0032] Referring to Figures 3-9 , the anti-edge lifting assembly 9 comprises an edge pressing table 901, the edge pressing table 901 is transversely and slidingly installed in the unfolding platform 602, the negative pressure disc 616 is provided with a supporting rod 905 at the top, and the supporting rod 905 is connected with the edge pressing table 901 through the connecting rod 904; when the negative pressure disc 616 moves upward, the negative pressure disc 616 drives the edge pressing table 901 to move in the direction close to the negative pressure disc 616 through the supporting rod 905 and the connecting rod 904.

[0033] Specifically, the edge pressing table 901 is internally provided with an anti-sticking roller 903, and a pressing gap 906 is reserved between the edge pressing table 901 and the edge pressing table 901.

[0034] Specifically, a transverse groove 902 is formed in the unfolding platform 602, and the transverse groove 902 is slidingly matched with the edge pressing table 901.

[0035] It should be noted that the way of lifting the two side edges of the label strip 502 is easy to make the label strip 502 bend outward, and after the label strip 502 is adhered to the surface of the substrate 501, the two sides of the label strip 502 are easy to lift, based on this, referring to Figures 7-8 ​With the upward movement of the negative pressure disc 616, the two side edges of the label strip 502 are gradually lifted, the negative pressure disc 616 drives the edge pressing table 901 to move towards the negative pressure disc 616 through the supporting rod 905 and the connecting rod 904, so that the edge of the label strip 502 is inserted into the pressing gap 906, as shown in Figure 8 When the edge pressing table 901 contacts the side wall of the negative pressure disc 616, the air cylinder 607 stops, and the anti-sticking roller 903 is driven to rotate, so that the anti-sticking roller 903 guides the edge of the label strip 502 into the pressing gap 906. Under the action of the pressing gap 906 and the anti-sticking roller 903, the edge part of the label strip 502 is bent towards the adhesive surface of the label strip 502, that is, the edge of the label strip 502 is bent in the opposite direction of the curling edge. When the pressing of the label strip 502 by the pressing roller 609 is completed, the curling of the label strip 502 can be effectively prevented.

[0036] Referring to Figure 2 and Figure 9 , the label strips 502 on the substrate 501 are arranged at intervals; when the electromagnetic suction disc 10 is electrified to adsorb the magnetic suction strips 606, the magnetic suction strips 606 on the exhibition platform 602 press the substrate 501 through the gaps between the label strips 502.

[0037] It should be noted that, in the present application, the magnetic suction strips 606 at both ends of the exhibition platform 602 press the substrate 501 through the gaps between the label strips 502 by electrifying the electromagnetic suction disc 10 to adsorb the magnetic suction strips 606, so as to fix the substrate 501, and make it easier for the negative pressure disc 616 to lift the two side edges of the label strip 502.

[0038] The implementation principle of the present application is as follows: Before detection, the label roll to be detected is installed on the feeding roller 3, and then the label strip 5 on the label roll is flattened and connected to the collecting roller 4.

[0039] During detection, the feeding roller 3 and the collecting roller 4 drive the label strip 5 to pass through the visual detection assembly 7, and the characters on the label strip 502 are detected and recognized by the visual detection assembly 7, so as to detect whether the label strip 502 is broken, etc. If the label strip 502 on the substrate 501 is wrinkled, when the label strip 502 moves to the bottom of the pressing assembly 6, the feeding roller 3 and the collecting roller 4 stop, and the electromagnetic suction disc 10 is electrified to adsorb the magnetic suction strips 606. At this time, the magnetic suction strips 606 at both ends of the exhibition platform 602 press the substrate 501 through the gaps between the label strips 502, and the negative pressure disc 616 is attached to the two side edges of the label strip 502. The negative pressure disc 616 sucks the two side edges of the label strip 502 through negative pressure; The starting cylinder 607 pushes the push block 608 to move downward, and the push block 608 rolls the label strip 502 from the center to the two sides through the bottom pressing roller 609, at the same time, the push block 608 drives the driving rack 612 to move synchronously through the inserting rod 610, under the transmission relationship of the driving rack 612, the gear 613 and the driven rack 614, the push block 608 drives the driven rack 614 and the negative pressure disc 616 to move upward, and the label strip 502 is separated from the base material 501 through the negative pressure disc 616, as shown in Figure 9 ; With the movement of the push block 608, the two sides of the label strip 502 are lifted by the negative pressure disc 616, so that the height difference between the center and the two sides of the label strip 502 gradually increases, and the label strip 502 is rolled by the pressing roller 609, so that the wrinkles on the label strip 502 are unfolded; with the continuous movement of the push block 608, the label strip 502 is pressed on the base material 501 again by the pressing roller 609, so that the label strip 502 is attached to the base material 501, thereby effectively avoiding the overlapping of characters on the label strip 502 and reducing the identification difficulty of the visual detection assembly 7.

[0040] Specifically, the way of lifting the two sides of the label strip 502 easily causes the label strip 502 to bend outward, and after the label strip 502 is attached to the surface of the base material 501, the two sides of the label strip 502 are easy to be lifted, based on this, referring to Figures 7-8 , with the upward movement of the negative pressure disc 616, the two sides of the label strip 502 are gradually lifted, and the negative pressure disc 616 drives the pressing edge table 901 to move close to the negative pressure disc 616 through the supporting rod 905 and the connecting rod 904, so that the edge of the label strip 502 is inserted into the pressing gap 906, as shown in Figure 8 , when the pressing edge table 901 contacts the side wall of the negative pressure disc 616, the cylinder 607 stops, and the anti-sticking roller 903 is driven to rotate, so that the anti-sticking roller 903 guides the edge of the label strip 502 into the pressing gap 906, under the action of the pressing gap 906 and the anti-sticking roller 903, the edge part of the label strip 502 bends to the sticking surface of the label strip 502, that is, the edge of the label strip 502 bends to the opposite direction of the lifting edge, and when the rolling of the label strip 502 by the pressing roller 609 is completed, the lifting edge of the label strip 502 can be effectively prevented.

[0041] The basic principles, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.
