Description

Technical Field

[0001] This utility model relates to the field of labeling equipment technology, specifically to an online labeling device. Background Technology

[0002] With the upgrading of manufacturing automation and the deepening demand for product traceability management, the requirements for online labeling operations in the fields of food, medicine, electronic components and logistics packaging are becoming increasingly stringent. They not only need to meet the needs of continuous production scenarios, but also need to adapt to the flexible production needs of multi-specification products and multi-type labels.

[0003] The label suction components of existing equipment mostly adopt rigid connection structures and lack elastic buffer design. When contacting irregularly shaped products or flexible packaging surfaces, uneven pressure can easily cause labels to shift or wrinkle, or labels to lift or fall off due to insufficient compaction. Some equipment relies on manual preset label suction positions, which is not only cumbersome to operate, but also prone to poor labeling consistency of products in the same batch due to human error, especially for small electronic component labels.

[0004] Secondly, most online labeling equipment does not integrate a real-time detection module. After labeling, it is necessary to rely on manual visual inspection of the label position, flatness and integrity, which not only consumes the labor cost of multiple operators, but also poses the risk of missed detection and false detection.

[0005] To address these issues, we designed an online labeling device. Summary of the Invention

The robotic arm 22 drives the suction nozzle mechanism 24 to move between the label feeder 4 and the conveying mechanism 5, and cooperates with the photographing mechanism 25 to complete label picking, application and quality detection.

[0049] In practice, the fixed base 21 fixes the robotic arm 22 to the mounting plate 1. The robotic arm 22 drives the suction nozzle mechanism 24 through the robotic arm connecting shaft 23, and moves precisely between the label feeding area of ​​the label feeder 4 and the labeling area of ​​the conveying mechanism 5.

[0051] In practice, the connecting shaft 254 is connected to the robotic arm connecting shaft 23, and the cylinder 245 drives the suction nozzle 253 to rise and fall. When picking up the label, the negative pressure sucks up the label. When labeling, the cylinder 245 pushes the suction nozzle 253 to contact the product, and the connecting plate 251 compresses the spring 248 on the mounting column 247 to generate a uniform elastic force to press the label.

The label tape of the label feeding tray 42 is guided by the auxiliary rotation mechanism 47, the width adjustment mechanism 45 adapts the width, and the peeling mechanism 46 peels off the label. The active rotation mechanism 48 provides power, and the waste tape is finally recycled to the recycling tray 43. The active rotation mechanism 48 drives the label tape to move through the motor 4820 and belt drive, and tightens the adjusting screw 4816 to adjust the tension of the label tape.

By turning the adjusting nut 4904, the lead screw 4902 is driven to rotate, which drives the lead screw nut 4903 and the fixing plate 7 4809 to move along the guide rail 4905, thereby adjusting the label supply position of the fixing plate 3 41 and the label feeder 4.

[0065] In practice, on the guide rail 4905 of the fixed plate 6 4808, the slider 4906 and the lead screw nut 4903 are fixedly connected to the fixed plate 7 4809; turning the adjusting nut 4904 drives the lead screw 4902 to rotate, which in turn drives the lead screw nut 4903, the fixed plate 7 4809 and the fixed plate 3 41 to move along the guide rail 4905, and locks the handle 4907 to a fixed position.

[0066] Working principle: Before use, all electrical appliances inside and outside this device need to be connected to an external power source, or a battery pack needs to be installed in an area outside this device that does not obstruct other components. Then, the battery pack is connected to the electrical appliances through wiring. It is also necessary to avoid the wiring from getting tangled due to the movement of the components. Wiring needs to be buried and planned and organized to provide power to the electrical appliances, thereby ensuring their normal operation and switching. Since connecting the electrical appliances to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.

[0067] In use, rodless cylinder 33 drives moving slider 32, which moves suction nozzle 39 to the receiving area; piston rod of cylinder 35 extends, and suction nozzle 39 adsorbs the product through negative pressure after contacting the product.

[0068] Cylinder 2 35 retracts to lift the product, and rodless cylinder 33 transfers the product to a position directly above the conveyor belt of conveyor mechanism 5; cylinder 2 35 extends again, suction nozzle 2 39 releases negative pressure to place the product, and the fixed base 51 is fixed to the mounting plate 1. The blocking cylinder 52 is installed on the mounting plate 1 via cylinder connector 53 and locked by fixing nut 54. The conveyor belt moves the product towards the labeling area. After reaching the preset position, the piston rod of blocking cylinder 52 extends to block the product, and the conveyor belt stops at the same time; after labeling is completed, blocking cylinder 52 retracts.

[0069] Tightening the adjusting nut 4904 of the adjusting mechanism 49 causes the lead screw 4902 to move the lead screw nut 4903 and the fixing plate 41, and after adapting to the labeling position, it is locked by the locking handle 4907; the label tape of the label feeding tray 42 is guided by the auxiliary rotating mechanism 47, and then the width adjusting mechanism 45, that is, the sliding width adjusting plate 4503, makes the width adjusting block 4502 fit the edge of the label tape, and the inclined plate 4504 flattens the label tape to prevent wrinkles; the pressure plate 4603 of the peeling mechanism 46 slides to adjust the spacing, the pressure block 4602 presses the base tape, and when the label tape passes the edge of the peeling plate 4601, the label separates from the base tape; the motor 4820 of the active rotating mechanism 48 drives the label tape through belt transmission. The recycling tray 43 rotates, providing power for the label tape to move. Tightening the clamping adjustment screw 4816 adjusts the tension, and the waste base tape wraps around the recycling tray 43 to complete recycling. Then, the robotic arm 22 drives the suction nozzle mechanism 24 to move to the label area via the robotic arm connecting shaft 23. Cylinder 245 extends, and suction nozzle 253 contacts the label, applying negative pressure for adsorption. Cylinder 245 retracts, and the robotic arm 22 moves the label towards the product. Once the suction nozzle mechanism 24 is above the product, cylinder 245 extends to bring the label into contact with the product. Cylinder 245 continues to extend, and connecting plate 251 compresses spring 248, generating elasticity to press the label firmly to prevent it from lifting. Suction nozzle 253 releases the negative pressure, and the robotic arm 22 resets.

[0070] While the label is being applied, the camera 2503 of the photographing unit 25 captures images of the label and checks its position and flatness; if it passes the test, the equipment proceeds to the next cycle.
