Description

Technical Field

[0001] This utility model relates to the field of product labeling technology, and in particular to an automatic labeling machine. Background Technology

[0002] With social development, people's material lives are becoming increasingly abundant, and various products are becoming more diverse. Generally, products need to be labeled with their own unique tags, which can be QR codes or barcodes that record their attributes such as trademarks, product names, weights, volumes, and uses.

[0003] During the production process, since each label needs to be affixed to a designated location, and the labels are generally small, manual labeling requires a lot of manpower, increasing labor costs. Furthermore, due to varying levels of operator skill, production efficiency and quality cannot be guaranteed, and labels are prone to being applied crookedly.

[0004] Therefore, there is a need to provide an automatic labeling machine to solve the above problems. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an automatic labeling machine that eliminates the need for manual labeling by workers, thereby improving the efficiency and quality of product labeling, reducing the labor intensity of workers, and lowering the production costs for enterprises.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic labeling machine, including a product feeding component, a labeling mechanism, and a detection component; the product feeding component can transfer products on a product carrier to below the labeling mechanism; the labeling mechanism includes a material picking component and a label feeding component that transfers labels to below the material picking component for material picking; the label feeding component includes a retractable peeling plate; the material picking component includes a vacuum suction head for adsorbing labels on the labels; during material picking, the peeling plate can peel a portion of the label from the base film on the label and transfer it to below the vacuum suction head; the detection component includes a detection camera for taking pictures of the labeled products.

[0007] Furthermore, the product loading assembly includes a loading module and an angle adjustment drive unit located thereon. The product carrier is located at the drive end of the angle adjustment drive unit. A receiving slot for placing the product is formed in the middle of the product carrier. Several positioning pins are vertically arranged within the receiving slot. At least one adjustable limiting block is provided on two adjacent sides of the product carrier near the edge. The cooperation between the receiving slot and the positioning pins provides initial positioning of the placed product. Adjusting the position of the limiting block on the product carrier ensures that adjacent sides of the product abut against the sides of the limiting block near the receiving slot, preventing the product from shifting position during transport and thus avoiding affecting the accurate application of subsequent labels.

[0008] Furthermore, the limiting block has a through-hole in the direction of the receiving groove. When the limiting block is locked with the product carrier, the adjusting screw passes through the through-hole and is threadedly connected to the product carrier. The design of the through-hole and the limiting block allows the product carrier to accommodate products of different sizes, making it more versatile. It eliminates the need for frequent fixture changes for different models of products to be labeled, thereby effectively reducing the processing costs for enterprises.

[0009] Furthermore, the label feeding assembly also includes a mounting bracket, a fixed bracket vertically mounted on the mounting bracket, and a telescopic assembly. The telescopic assembly includes a horizontally mounted telescopic bracket and a telescopic cylinder horizontally mounted on the fixed bracket. The inner side of the telescopic bracket is slidably connected to the side of the fixed bracket away from the detection component via a slide rail. The drive end of the telescopic cylinder is connected to the telescopic bracket to drive the peeling plate mounted on the telescopic bracket near the material-taking component to move back and forth. The telescopic cylinder can drive the telescopic bracket to move back and forth along the slide rail to adjust the relative position between the peeling plate and the vacuum suction head, avoiding interference when the vacuum suction head moves up and down.

[0010] Furthermore, the label feeding assembly also includes a feeding drive assembly, a feeding reel, a label feeding roller, and several guide rollers mounted on a fixed bracket. The labels on the feeding reel are sequentially wound around the label feeding roller, guide roller, peeling plate, and outer winding roller.

[0011] Furthermore, the material-taking assembly is connected to the label-feeding assembly via a vertically mounted mounting plate. A pressure cylinder is mounted on the side of the mounting plate closest to the product carrier. A lower pressure plate is mounted on the driving end of the pressure cylinder. The side of the pressure cylinder furthest from the mounting plate is slidably connected to the connecting frame of the material-taking cylinder's driving end via a guide rail. The vacuum suction head is adjustablely mounted on the connecting frame. After the peeling plate is moved below the material-taking assembly by the telescopic cylinder, the drive motor drives the label-feeding roller to feed the label until it reaches the peeling plate and partially peels off the base film. Subsequently, the piston rod of the pressure cylinder extends, causing the lower pressure plate to move downwards and press the portion of the label near the peeling plate against the support plate located on the side of the peeling plate, facilitating the vacuum suction head to peel the label off the base film.

[0012] Furthermore, the detection assembly also includes a support frame, on which a lighting bracket and a detachable lighting plate are disposed below the detection camera. The lighting plate has a clearance hole in the middle corresponding to the position of the detection camera.

[0013] The detection component is located on the side of the label feeding component, specifically close to the initial product feeding end. The light plate illuminates the labeled products that have moved below it, so that the detection camera can capture images more accurately and ensure the accuracy of the pass detection.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, the product feeding component, label feeding component, material handling component, and detection component work together to ensure that the entire process of label feeding, product feeding, label application, and post-application detection does not require manual operation by staff. This effectively improves the efficiency and quality of product labeling, reduces the labor intensity of staff, and lowers the production costs for enterprises. Attached Figure Description

Detailed Implementation

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0025] See appendix Figures 1 to 7 As shown, an automatic labeling machine in this embodiment includes a product feeding component 3, a labeling mechanism, and a detection component 12. The product feeding component 3 can transfer the products on the product carrier 4 to the area below the labeling mechanism. The products to be labeled are automatically picked up and placed into the product carrier 4 by an external robotic arm. The product feeding component 3 transfers the product carrier 4 containing the products to the area below the labeling mechanism for subsequent automatic labeling. There is no need for manual feeding, which can reduce the labor intensity of the workers.

[0026] The labeling mechanism includes a material picking component 11 and a label feeding component 7 that moves the label to the bottom of the material picking component 11 for material picking. The label feeding component 7 includes a retractable peeling plate 73. The peeling plate 73 is designed to automatically peel off the label from the label, making it convenient for the material picking component 11 to pick up the material. On the other hand, the retractable design ensures that after the peeling plate 73 feeds the material, it will not interfere with the vacuum suction head 112 continuing to move downwards to press the label onto the product.

[0027] The material-picking assembly 11 includes a material-picking cylinder 111 and a vacuum suction head 112 for adsorbing labels. During material picking, the peeling plate 73 can peel a portion of the label from the base film on the label and move it below the vacuum suction head 112. The vacuum suction head 112 is connected to an external air pump. When the air pump is activated, it uses an air suction pipe to firmly suction the side of the label away from the base film onto the vacuum suction head 112. The extension end of the material-picking cylinder 111 moves upward, causing the vacuum suction head 112 to move upward, thereby completely peeling the label from the base film. Subsequently, the piston rod of the material-picking cylinder 111 extends, driving the vacuum suction head 112 to move towards the surface of the product until the label is pressed firmly onto the product surface. Finally, the air pump is turned off, and the material-picking cylinder 111 resets, completing the entire labeling process. The entire process does not require manual labeling by staff, effectively improving the efficiency and quality of product labeling, reducing the labor intensity of staff, and lowering the production costs of enterprises.

[0028] The detection component 12 includes a detection camera 122 for taking pictures of the labeled product. The detection camera 122 is used to detect whether the label on the product is affixed to the corresponding position. Specifically, the detection camera 122 takes a picture of the labeled product and transmits the image to an external display. The external display compares the received image with a comparison image. If the label position is off, it is determined to be a defective product, and an external robotic arm will pick it up and move it to the defective area; otherwise, an external robotic arm will pick it up and move it to the qualified area.

[0029] The product loading assembly 3 includes a loading module 31 and an angle adjustment drive 32 located thereon. The product carrier 4 is located at the drive end of the angle adjustment drive 32. The product carrier 4 has a receiving groove in the middle for placing the product. Several positioning pins 5 are vertically arranged in the receiving groove. At least one adjustable limiting block 6 is provided on two adjacent sides of the product carrier 4 near the edge. The cooperation between the receiving groove and the positioning pins 5 can initially position the placed product. Adjusting the position of the limiting block 6 on the product carrier 4 ensures that the adjacent two sides of the product abut against the side of the limiting block 6 near the receiving groove, ensuring that the product will not shift position when the product carrier 4 transports the product, thereby avoiding affecting the accurate application of subsequent labels.

[0030] In some embodiments, the angle adjustment drive 32 is a drive motor 751 or an indexing plate, used to adjust the angle of the product carrier 4 to ensure that the position on which the label needs to be attached corresponds precisely to the vacuum suction head 112, and to ensure that the label is attached without any skewing. The feeding module 31 can also be a linear cylinder or other known mechanical structure that can drive the product carrier 4 to be conveyed to the labeling mechanism below.

[0031] The limiting block 6 has a through-hole 61 along the direction towards the receiving groove. When the limiting block 6 is locked with the product carrier 4, the adjusting screw 62 passes through the through-hole 61 and is threadedly connected to the product carrier 4. The setting of the through-hole 61 and the limiting block 6 allows the product carrier 4 to accommodate products of different sizes for positioning, making it more versatile. It also eliminates the need for frequent fixture changes for different models of products to be labeled, thereby effectively reducing the processing costs for enterprises.

[0032] The label feeding assembly 7 also includes a mounting bracket 71, a fixed bracket 72 vertically mounted on the mounting bracket 71, and a telescopic assembly 74. The telescopic assembly 74 includes a horizontally mounted telescopic bracket 742 and a telescopic cylinder 741 horizontally mounted on the fixed bracket 72. The inner side of the telescopic bracket 742 is slidably connected to the side of the fixed bracket 72 away from the detection assembly 12 via a slide rail. The driving end of the telescopic cylinder 741 is connected to the telescopic bracket 742 to drive the peeling plate 73 mounted on the telescopic bracket 742 near the material picking assembly 11 to move back and forth. The telescopic cylinder 741 can drive the telescopic bracket 742 to move back and forth along the slide rail to adjust the relative position between the peeling plate 73 and the vacuum suction head 112, avoiding interference when the vacuum suction head 112 moves up and down.

[0033] The label feeding assembly 7 also includes a feeding drive assembly 75, a feeding reel 76, a label feeding roller 78, and several guide rollers 77, all mounted on a fixed bracket 72. The labels on the feeding reel 76 are sequentially wound around the label feeding roller 78, the guide rollers 77, the peeling plate 73, and the outer winding roller.

[0034] In some embodiments, the feeding drive assembly 75 includes a drive motor 751, the drive end of the drive motor 751 is connected to a drive wheel, and the roller shaft ends of the guide roller 77 and the label feeding roller 78 are provided with driven rollers. The drive roller and the driven roller are connected by a drive belt. When the drive motor 751 drives the drive wheel to rotate, the driven wheel can also rotate. The label feeding roller 78 and the guide roller 77 rotate to feed the label, thereby realizing automatic label feeding.

[0035] In some embodiments, a tension roller 743 is hinged to one end of the telescopic bracket 742 away from the peeling plate 73. After the label is removed, the waste base film is tensioned by the tension roller 743 and then wound onto the outer winding roller. The outer winding roller is driven by a winding motor, which can drive the outer winding roller to rotate and automatically wind up the waste.

[0036] The material-taking assembly 11 is connected to the label-feeding assembly 7 via a vertically mounted mounting plate 8. A pressure cylinder 9 is mounted on the side of the mounting plate 8 near the product carrier 4. A lower pressure plate is mounted on the driving end of the pressure cylinder 9. The side of the pressure cylinder 9 away from the mounting plate 8 is slidably connected to the connecting frame 113 at the driving end of the material-taking cylinder 111 via a guide rail 10. The vacuum suction head 112 is adjustablely mounted on the connecting frame 113. After the peeling plate 73 is moved to below the material-taking assembly 11 under the drive of the telescopic cylinder 741, the drive motor 751 drives the label-feeding roller 78 to feed the label until it reaches the peeling plate 73 and partially peels off the base film. Subsequently, the piston rod of the pressure cylinder 9 extends, causing the lower pressure plate to move downwards and press the portion of the label near the peeling plate 73 against the support plate 79 located on the side of the peeling plate 73, facilitating the vacuum suction head 112 to peel the label off the base film.

[0037] The connecting bracket 113 has several connecting holes along its length. The top of the vacuum adsorption head 112 is threadedly fastened to the corresponding connecting hole by screws to adapt to products with different label attachment positions.

[0038] It should be noted that the specific structure of the peeling plate 73 is existing technology. Its lower surface is inclined on the side closest to the product to reduce the thickness of the peeling plate 73 near the product, which facilitates automatic peeling of the label. Its specific structure will not be described in detail here.

[0039] The detection assembly 12 also includes a support frame 121, on which a lighting bracket 124 is provided below the detection camera 122 and a lighting plate 123 is detachably provided. A clearance hole 125 corresponding to the position of the detection camera 122 is provided in the middle of the lighting plate 123.

[0040] The detection component 12 is located on the side of the label feeding component 7, specifically close to the initial product feeding end. The light plate 123 illuminates the labeled product that has moved below it, so that the detection camera 122 can capture images more accurately and ensure the accuracy of the qualified detection.

[0041] It also includes a workbench 1, a product feeding component 3, a label feeding component 7, a material picking component 11, and a detection component 12, all of which are located on the workbench 1. A protective cover 2 is also installed on the workbench 1.
