Description

Technical Field

[0001] This utility model relates to the field of labeling mechanism technology, specifically to an automatic labeling mechanism for QR codes. Background Technology

[0002] A QR code is a black and white graphic that uses a specific geometric pattern to represent data symbols on a plane. In production operations, QR codes are often attached to products using a mounting structure.

[0003] For example, the patent with announcement number CN220363588U (an automatic QR code label affixing mechanism) includes a support plate, with multiple support columns fixedly connected to the bottom of the support plate, and a drive assembly installed on one side of the top of the support plate; two support bars are fixedly connected to the rear end of the top of the support plate, two slide rods are fixedly connected between the two support bars, a moving assembly is installed between the two slide rods, a cylinder is installed on the top of the moving assembly, and a suction cup is fixedly connected to the bottom end of the cylinder piston; an mounting plate is fixedly connected to the other side of the top of the support plate, and an affixing rotation assembly is installed at the front end of the mounting plate;

[0004] While the existing technology can automatically transport the labeled products, it uses a single labeling head for labeling. The time required for a single head to complete one cycle of label picking, moving, attaching, and returning limits the efficiency of QR code labeling. To increase the speed, the operating speed of the mechanism must be increased, but this will lead to problems such as increased vibration and faster wear. Therefore, there is an urgent need in the market to develop an automatic QR code labeling mechanism to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic QR code label applicator to solve the problem mentioned in the background art, which is that the time required for a single head to complete one cycle of label picking, moving, affixing, and returning limits the efficiency of QR code applicator.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic QR code label application mechanism, comprising a strip plate, a conveyor belt device provided on one side above the strip plate, upright plates symmetrically fixedly installed on both sides above the strip plate, a screw box one provided at the front and rear ends between the two upright plates, a suction mechanism provided at the front end of the screw box one, the suction mechanism comprising a translation plate, a platform, an electric cylinder, an equipment box and a vacuum suction cup, a screw box two fixedly installed on the other side above the strip plate, a back plate provided above the screw box two, and rotating drum one and rotating drum two symmetrically rotatably installed on both sides of the front end of the back plate.

[0007] Preferably, the translation plate is disposed at the front end of the screw box, the platform is fixedly installed below the front end of the translation plate, the electric cylinder is fixedly installed above the platform, and the equipment box is disposed below the platform.

[0008] Preferably, the vacuum suction cup is fixedly installed at the bottom of the equipment box, and the push rod end of the electric cylinder slides through the platform and is fixedly connected to the equipment box.

[0009] Preferably, a feed plate is fixedly installed at the front end of the back plate between the first rotating drum and the second rotating drum, and the upper end surface of the feed plate is arc-shaped.

[0010] Preferably, guide mechanisms are symmetrically arranged on both sides below the back plate, and the guide mechanism includes a fixed plate, a guide rod and a guide plate.

[0011] Preferably, there are two fixing plates, which are respectively fixedly installed at both ends of the guide rod.

[0012] Preferably, the guide plate is slidably sleeved on the outside of the guide rod, and the upper end of the guide plate is fixedly connected to the back plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses two lead screw boxes to drive two suction mechanisms to achieve left and right translation for label picking, while the lead screw box drives the back plate and rotating drum structure to achieve front and back movement. This multi-axis coordinated motion design can improve the application efficiency, reduce the problems of increased vibration and accelerated wear caused by simply increasing the running speed, and increase practicality.

[0015] 2. This utility model, by setting a feed plate, can support the label tape unwound from the QR code label. At the same time, the upper end face of the feed plate is arc-shaped, which can smoothly guide the QR code label tape fed out from the rotating drum. This helps to ensure that the label tape always sticks to the feed plate and moves forward smoothly, making it easier for the vacuum suction cup to pick up the QR code label, thus increasing its practicality.

[0016] 3. By setting a guiding mechanism, including a fixed plate, a guide rod and a guide plate, this utility model can provide guidance and stable support for the back panel's forward and backward movement, ensuring the back panel moves in a straight line and improving the stability of the back panel's movement.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of an automatic QR code label application mechanism, comprising a strip plate 1, a conveyor belt device 9 disposed on one side above the strip plate 1, upright plates 2 symmetrically fixedly installed on both sides above the strip plate 1, a screw box 3 disposed at the front and rear ends between the two upright plates 2, a suction mechanism disposed at the front end of the screw box 3, the suction mechanism comprising a translation plate 4, a platform 5, an electric cylinder 6, an equipment box 7, and a vacuum suction cup 8, and a screw... The inner parts of the second screw box 11, the first screw box 3, and the second screw box 11 are all equipped with ball screw mechanisms, which are used to drive the translation plate 4 to move left and right and the back plate 10 to move back and forth, respectively. The back plate 10 is set on the top of the second screw box 11. The first rotating drum 13 and the second rotating drum 14 are symmetrically rotated on both sides of the front end of the back plate 10. The drive motors of the first rotating drum 13 and the second rotating drum 14 are set at the rear end of the back plate 10. The first rotating drum 13 is used to hold the QR code roll, and the second rotating drum 14 is used to wind up the back paper of the QR code.

[0024] By setting up two lead screw boxes, two suction mechanisms are driven to move left and right to pick up the labels. At the same time, the back plate and the rotating drum structure are driven by the second lead screw box to move back and forth. Thus, through the alternating operation of the two suction mechanisms, when one suction mechanism is performing the labeling action, the other suction mechanism can simultaneously perform the label picking operation, which improves the labeling efficiency of QR codes and increases practicality.

[0025] Furthermore, the translation plate 4 is located at the front end of the screw box 3, the platform 5 is fixedly installed below the front end of the translation plate 4, the electric cylinder 6 is fixedly installed above the platform 5, the equipment box 7 is located below the platform 5, the vacuum suction cup 8 is fixedly installed below the equipment box 7, and the equipment box 7 is equipped with a vacuum pump for the vacuum suction cup 8. The push rod end of the electric cylinder 6 slides through the platform 5 and is fixedly connected to the equipment box 7.

[0026] The electric cylinder 6 drives the equipment box 7 and the vacuum suction cup 8 to move up and down, thereby realizing the label picking and labeling actions. By setting up a vacuum pump, a stable suction force is provided to the vacuum suction cup, ensuring that the QR code label can be firmly adsorbed and released during the label picking and labeling process.

[0027] Furthermore, a feed plate 15 is fixedly installed at the front end of the back plate 10 between the first rotating drum 13 and the second rotating drum 14, and the upper end surface of the feed plate 15 is arc-shaped.

[0028] The arc-shaped upper surface of the feed plate 15 can smoothly guide the QR code label tape fed from the rotary drum 13, providing a continuous, non-sharp-angle transition support surface for the label tape. At the same time, the arc-shaped guide ensures that the label tape always stays close to the feed plate and moves forward smoothly, reducing the shaking and deviation of the label during the conveying process. This makes it easier for the vacuum suction cup 8 to stably pick up the QR code label each time, increasing its practicality.

[0029] Furthermore, guide mechanisms 12 are symmetrically arranged on both sides below the back plate 10. The guide mechanism 12 includes a fixed plate 1201, a guide rod 1202 and a guide plate 1203. There are two fixed plates 1201, which are fixedly installed at both ends of the guide rod 1202. The guide plate 1203 is slidably sleeved on the outside of the guide rod 1202, and the upper end of the guide plate 1203 is fixedly connected to the back plate 10.

[0030] The guide mechanism 12 provides guidance and stable support for the back plate 10 to move back and forth. When the lead screw box 11 drives the back plate 10 to move, the guide plate 1203 slides along the guide rod 1202, ensuring that the back plate 10 moves in a straight line without deviation or shaking, thereby improving the accuracy and stability of the back plate 10's movement.

[0031] Working Principle: During use, the conveyor belt device 9 continuously transports the products to be labeled to the workstation. Simultaneously, it drives the rotating drum 13 and rotating drum 2 14 to rotate synchronously, unwinding the QR code roll. Two suction mechanisms driven by screw box 1 3 work alternately. When one suction mechanism moves left or right to the label-taking station driven by screw box 1 3, its electric cylinder 6 pushes the equipment box 7 and vacuum suction cup 8 to descend, the built-in vacuum pump starts, and after firmly adhering to the label, it is lifted. Then, screw box 1 3 drives the mechanism to move above the product, and electric cylinder 6 descends again for precise labeling. At the same time, the vacuum is released. During this process, the other suction mechanism simultaneously performs the label-taking action. Screw box 2 11 drives the back plate 10 to move back and forth to coordinate with the suction mechanism to adjust the material-taking position, thereby improving the efficiency of QR code label application and increasing practicality.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
