Description

Technical Field

[0001] This utility model relates to the field of laser marking and coating technology, and more specifically, to a variable QR code label laser marking and coating integrated machine. Background Technology

[0002] In modern product identification and traceability systems, variable QR code labels play a crucial role, carrying a wealth of information such as product batch number, production date, logistics trajectory, and quality inspection data, providing key support for product lifecycle management. Currently, the manufacturing process of variable QR code labels encompasses a variety of technologies.

[0003] Laser marking machines use high-energy-density lasers to locally irradiate workpieces, causing the surface material to vaporize or undergo a chemical reaction that changes color, thereby leaving permanent marks such as electronic component labels, barcodes, and QR code markings. After QR code marking is completed, a lamination process is indispensable to protect the QR code label from external environmental factors and ensure the long-term readability and integrity of its information.

[0004] However, in the existing variable QR code label production process, the laser coding equipment and the laminating equipment are often independent of each other. This means that in actual production, the QR code must first be completed on the laser coding equipment, and then the coded label must be transferred to the laminating equipment for lamination. This increases the production process and procedures, and the transfer of products between different devices not only consumes a lot of time and labor costs, but also reduces the overall production efficiency. Moreover, multiple transfers of labels can easily cause scratches and dirt on the label surface, affecting the clarity and readability of the QR code, and thus affecting the accuracy of product traceability and management.

Detailed Implementation

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] As attached Figure 1 To be continued Figure 3 The present invention provides a variable QR code label laser coding and coating integrated machine, including a coding machine body 1, a wind cooling device 2 fixedly installed in the middle of the coding machine body 1, a positioning device 3 fixedly installed on the top of the coding machine body 1 to the right of the wind cooling device 2, and a coating device 4 fixedly installed on the right side of the top of the coding machine body 1.

[0027] like Figure 3 As shown, the air-cooled device 2 includes a fixed frame 21. An air outlet 22 is fixedly installed on the top of the fixed frame 21. An air supply pipe 23 is fixedly connected to the side of the air outlet 22. One end of the air supply pipe 23 is fixedly connected to a dust collection box 24. A connecting groove 27 is fixedly connected inside the dust collection box 24. A blower 28 is fixedly connected inside the connecting groove 27. A dust collection bag 26 is embedded in the left side of the top of the dust collection box 24. A filter screen 25 is detachably installed on the left side of the top of the dust collection box 24 above the dust collection bag 26.

[0028] Using the dust collection bag 26, air enters the interior of the dust collection bag 26 through the filter screen 25 and is filtered to prevent dust from adhering to the surface of the product during the air cooling process, making the product surface cleaner and avoiding excessive dust on the product surface, which could affect the coating of the product.

[0029] like Figure 2As shown, the coding machine body 1 includes a conveyor 11, a fixing plate 12 is fixedly installed at the lower end of the conveyor 11, a laser coding machine 13 is fixedly installed on the left side of the top of the conveyor 11, an inspection frame 14 is fixedly installed on the right side of the top of the conveyor 11, a QR code verifier 15 is fixedly installed on the top of the inspection frame 14, a push cylinder 16 is fixedly installed on the side of the inspection frame 14, a push plate 17 is fixedly connected to the output end of the push cylinder 16, the push plate 17 is slidably installed on the top of the conveyor 11, and a discharge chute 18 is fixedly installed on the side of the conveyor 11, the discharge chute 18 is located on the side of the inspection frame 14.

[0030] The fixing frame 21 is fixedly installed on the top of the conveyor 11, and the dust collection box 24 is fixedly installed on the top of the fixing plate 12.

[0031] The QR code verifier 15 scans and detects the QR code on the product to determine whether the QR code is complete and correct. When the QR code verifier 15 detects that the QR code is incorrect or incomplete, it will control the cylinder 16 to extend through the electrical signal, so that the pusher plate 17 pushes the product with the incomplete QR code to the top of the feeding trough 18. The product is then sorted through the feeding trough 18, thereby rejecting defective products in advance.

[0032] like Figure 4 As shown, the positioning device 3 includes two side frames 31, which are fixedly installed on both sides of the top of the conveyor 11. A positioning cylinder 34 is fixedly installed on the side of each side frame 31, and a positioning plate 35 is fixedly installed on the side of each positioning cylinder 34. Limiting rods 36 are fixedly installed on both sides of the positioning plate 35. The limiting rods 36 are movably sleeved inside the side frame 31. A top frame 32 is fixedly installed on the top of each side frame 31, and a photoelectric sensor 33 is fixedly installed in the middle of the top frame 32.

[0033] The photoelectric sensor 33 is used to detect the conveyed product. When the product is detected, the photoelectric sensor 33 controls the positioning cylinders 34 at both ends to start through an electrical signal. The positioning plates 35 at both ends move closer to each other to position the product, which facilitates the QR code verifier 15 to scan the product. At the same time, it facilitates the film coating device 4 to coat the product.

[0034] like Figure 5As shown, the coating device 4 includes a coating frame 41, which is fixedly installed on the right side of the top of the conveyor 11. A roll unwinding shaft 42 is rotatably installed on the top of the coating frame 41. A movable frame 43 is fixedly installed on the left side of the lower end of the coating frame 41. An adjusting knob 44 is threadedly installed on the top of the movable frame 43. A pressing roller 45 is rotatably installed on the bottom of the adjusting knob 44. The pressing roller 45 is slidably installed inside the movable frame 43. A support frame is fixedly installed on the right side of the lower end of the coating frame 41. A moving motor 47 is fixedly installed on the side of the support frame. A rotating screw 48 is fixedly installed on the output end of the moving motor 47. The rotating screw 48 is rotatably installed inside the support frame. A cutting blade 49 is threadedly installed on the outer surface of the rotating screw 48. The cutting blade 49 is slidably installed inside the support frame. A guide roller 46 is rotatably installed on the left side of the movable frame 43.

[0035] By applying a film to the outer surface of the unwinding shaft 42 and pressing the film onto the surface of the product by the pressing roller 45 through the outer surface of the guide roller 46, the product is coated with film. After the product is conveyed to one end, the moving motor 47 controls the rotating screw 48 to rotate, causing the cutting blade 49 to reciprocate, thereby cutting the film.

[0036] The working process of this utility model is as follows:

[0037] In use, the product is conveyed by the conveyor 11. When it is conveyed to the bottom of the laser marking machine 13, the laser marking machine 13 marks the product. Then, the conveyor 11 continues to convey the product. As the conveyor 11 conveys the product, the blower 28 works, so that the air passes through the filter screen 25 through the inside of the dust collection bag 26 and is blown out from the air outlet 22 through the air supply pipe 23 to cool the product that has just been marked. This prevents the local temperature of the material surface from rising after laser marking, especially for heat-sensitive materials such as plastics and paper. When the film is immediately laminated, the residual heat will cause the air under the film to expand and form bubbles.

[0038] When the product is conveyed into the side frame 31, the photoelectric sensor 33 detects the conveyed product. After the product is detected, the photoelectric sensor 33 controls the positioning cylinders 34 at both ends to start through an electrical signal. The positioning plates 35 at both ends move closer to each other to position the product. Then, the conveyor 11 continues to convey the product and detects the QR code of the product through the QR code verifier 15. When the QR code verifier 15 detects that the QR code is incorrect or incomplete, it will control the cylinder 16 to extend through an electrical signal, so that the pusher plate 17 pushes the product with the incomplete QR code to the top of the discharge trough 18. The products are sorted through the discharge trough 18, thereby rejecting the defective products in advance.

[0039] The qualified products continue to be conveyed into the laminating device 4, and the film on the unwinding shaft 42 is pressed onto the surface of the product by the pressing roller 45 to achieve the lamination of the product. After the product is conveyed to one end, the moving motor 47 controls the rotating screw 48 to rotate, so that the cutting blade 49 reciprocates, thereby cutting the film and realizing the integrated coding and lamination of the product.

[0040] Finally, it should be noted that: the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
