Description

Technical Field

[0001] This utility model relates to the field of label picking mechanism manufacturing technology, and in particular to a label picking mechanism. Background Technology

[0002] The label picking mechanism is a very common and important functional module in automated equipment. Simply put, it is a system that uses the principle of vacuum adsorption to automatically and accurately pick up and stick labels. The label picking mechanism is the basic technology for product identification, traceability and packaging in modern industrial automation. It combines the simple principle of vacuum adsorption with precise motion control and sensing technology to achieve efficient, high-precision and high-reliability automated operation that replaces manual operation.

[0003] In modern industrial production, such as in the electronics, food, and pharmaceutical industries, product packaging typically requires labels. For certain specific applications, it is necessary to affix two identical labels simultaneously at the same workstation or on the same product. Existing labeling mechanisms mostly employ single-head or fixed multi-head structures, which suffer from low efficiency, large space requirements, inability to flexibly buffer labels, and poor adaptability to curved or uneven surfaces. When dealing with curved or irregular product surfaces, traditional labeling mechanisms often cause labels to wrinkle or not adhere firmly due to uneven bonding pressure. Furthermore, most equipment cannot achieve dual label pickup and application, affecting production efficiency.

[0004] Therefore, how to provide a label-absorbing mechanism is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to propose a label-grabbing mechanism that uses a rotary cylinder to drive dual-station suction cups to alternately pick up labels, and utilizes a spring-guided structure to enable multiple suction cups to float independently. This allows the label to adapt to the undulations of the product surface during application, ensuring uniform pressure at each point, effectively avoiding bubbles and wrinkles, and significantly improving label bonding quality and production efficiency, thereby solving the problems mentioned in the background art.

[0008] As a further preferred embodiment of this utility model: a movable plate is fixedly connected to the end of the connecting plate away from the supporting plate, and the outer wall of the movable plate is provided with uniformly distributed adsorption holes.

[0009] As a further preferred embodiment of this utility model: two retractable rods are fixedly connected to the opposite side of the outer wall of the fixed plate, and the end of the retractable rod away from the fixed plate is fixedly connected to the support plate.

[0011] As a further preferred embodiment of this utility model: a fixed connecting plate is fixedly connected to the end of the rotating disk away from the rotating cylinder, and two fixed plates are fixedly connected to the outer wall of the fixed connecting plate.

[0012] The beneficial effects of this utility model are: By using a rotary cylinder to drive dual-station suction cups to alternately pick up labels, and utilizing a spring-guided structure to enable multiple suction cups to float independently, the labels can adapt to the undulations of the product surface during application, ensuring uniform pressure at each point, effectively avoiding bubbles and wrinkles, and significantly improving label application quality and production efficiency.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a label-absorbing mechanism includes a support plate 1, a fixed plate 2, and a rotary cylinder 8. A guide rod sleeve 4 is fixedly connected to the middle of the inner wall of the fixed plate 2. A guide rod 15 is slidably connected to the inner wall of the guide rod sleeve 4. A spring 14 is fixedly connected to the end of the guide rod 15 closest to it. The end of the spring 14 away from the guide rod 15 is fixedly connected to the support plate 1. A connecting plate 6 is fixedly connected to the outer wall of the support plate 1. A through groove 13 is opened on the inner wall of the connecting plate 6. A movable plate 7 is fixedly connected to the end of the connecting plate 6 away from the support plate 1. Evenly distributed adsorption holes 3 are opened on the outer wall of the movable plate 7. Two retraction rods 5 are fixedly connected to the opposite side of the outer wall of the fixed plate 2. The end of the retraction rod 5 away from the fixed plate 2 is fixedly connected to the support plate 1. A solenoid valve coil 1 9 and a solenoid valve coil 2 12 are fixedly connected to the input end of the rotary cylinder 8. A rotating disk 11 is fixedly connected to the output end of the rotary cylinder 8. A fixed connecting plate 10 is fixedly connected to the end of the rotating disk 11 away from the rotary cylinder 8. Two fixed plates 2 are fixedly connected to the outer wall of the fixed connecting plate 10.

[0022] This rotary label-grabbing mechanism achieves dual-station switching and label buffering through a rotary cylinder, uses a vacuum suction cup to grasp and release labels, and uses an elastic guide device to ensure flat and reliable labeling. This design cleverly processes two spatial stations and two temporal actions (label picking and labeling) in parallel, enabling two labeling tasks to be completed within one work cycle. It is particularly suitable for high-efficiency, dual-label automated production scenarios.

[0023] Working principle: During operation, the rotary cylinder 8 drives the rotary disk 11 to rotate. The rotation of the rotary disk 11 causes two fixed plates 2 at the ends furthest from it to rotate. The rotation of the fixed plates 2, in turn, causes the movable plate 7 to rotate via the retractable rods 5 on both sides. This movable plate 7 moves to the label-collecting station, where it picks up the first label through the suction holes 3 on its outer wall. The rotary cylinder then switches to the buffer station to pick up the second label. After both labels are picked up, the mechanism lowers as a whole via the lifting assembly. An elastic guide device ensures flexible contact between the vacuum suction cup and the product surface, simultaneously affixing both labels. If the product surface is uneven or the height of the movable plate 7 has slight differences, the contact point with the product surface... The suction holes 3 on the outer wall of the movable plate 7 will first come into contact with the product, and the spring 14 in the corresponding guide sleeve 4 will be compressed. The guide rod 15 will slide on the inner wall of the guide sleeve 4. This compression process allows the suction holes 3 on the outer wall of the movable plate 7 to "stop". Other suction cups that have not yet contacted the surface will continue to move downward under the continued downward pressure of the mechanism until they also contact the product surface. When all the suction holes 3 have contacted their surfaces, the springs in each guide sleeve 4 are in a state of compression to different degrees, but they all generate a continuous and uniform pressing force on the suction holes 3 of their respective movable plates 7. This ensures that every point of the label can be pressed evenly on the product surface.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
