Description

Technical Field

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

[0002] In the industrial manufacturing sector, the labeling process after product processing currently relies primarily on manual operation, with workers manually affixing labels to designated locations on the product surface. However, manual labeling inherently suffers from inefficiency. Its speed is limited by the operator's physical strength and skill level, making it difficult to match the high-paced production demands of modern assembly lines and easily becoming a bottleneck restricting capacity increases. Furthermore, manual operation is prone to label misalignment, tilting, or air bubbles due to fatigue or distraction, severely impacting product appearance consistency and readability. Moreover, with rising labor costs, companies must continuously invest significant funds to maintain repetitive labor. Although some scenarios have attempted to use semi-automatic labeling equipment (such as robotic arms combined with suction cups) to replace manual labor, existing equipment generally suffers from complex mechanical structures, low adaptability, and an inability to quickly respond to the labeling needs of multiple product specifications. Switching between production models requires time-consuming adjustments to the mechanical structure or reprogramming, resulting in insufficient flexibility. Therefore, there is an urgent need to develop a fully automatic labeling device that combines high precision, high adaptability, and modular design to overcome the dual limitations of efficiency and quality and meet the flexible and diversified production needs of the intelligent manufacturing era.

[0026] This utility model provides an automatic labeling device, such as... Figure 1 As shown, it includes a feeding mechanism 1, a label roll feeding mechanism 2, a label transfer mechanism 3, and a pressing mechanism 4.

[0027] In this embodiment, the feeding mechanism 1 is used to carry the product to be labeled and transport it to the pressing mechanism 4; the label roll take-up and untake-down mechanism 2 is used to fix the label roll and realize the recycling of residual material; the label transfer mechanism 3 is used to separate the label from the label roll and transfer it to the product surface; and the pressing mechanism 4 is used to apply pressure to the label and the product surface to achieve tight adhesion.

[0028] In one specific embodiment, such as Figure 2 As shown, the feeding mechanism includes: 1) a first slide table 11 and a tray 12 placed on the first slide table, the tray 12 having at least one cavity for positioning and fixing the product to be labeled; 2) a first robotic arm 13 and a clamping assembly 14 and a spray nozzle 15 fixed to the movable end of the first robotic arm; the clamping assembly 14 for clamping the tray 12 and transferring the tray 12 carrying the product to be labeled to the pressing mechanism 4; and the spray nozzle 15 for spraying adhesive onto the product to be labeled.

[0029] The body of the first robotic arm 13 has at least forward, backward, left and right position movement directions so that the output end of the first robotic arm 13 can output to any point within the planar range of motion. The output end of the first robotic arm 13 has up, down and rotation functions so that the tray 12 can be taken out or put down by the clamping component 14 by "up and down" and the angle of the clamping component 14 and the spray nozzle 15 can be adjusted by "rotation".

[0030] like Figure 3 As shown, the label roll take-up and take-down mechanism 2 includes a fixed frame 21, on which a roll reel 22 and a take-up reel 23 are fixedly connected. The roll reel 22 is used to load label rolls, and the take-up reel 23 is used to recycle the residual material after the labels are peeled off. The fixed frame 21 is also provided with a steering wheel 24.

[0031] The fixed frame 21 is also equipped with a drive motor 25, which is connected to the take-up reel 23 by belt drive. The drive motor 25 drives the take-up reel 23 to rotate, so as to realize automated processing.

[0032] The fixing frame is also provided with a support platform 26, which is located between the roll 22 and the steering wheel 24, and the height of the support platform 26 is higher than that of the steering wheel 24 to facilitate the peeling of the label.

[0033] Understandably, after the label roll is drawn out from the roll 22, it passes through the support platform 26, then around the steering wheel 24 and winds onto the take-up tray 23, forming a continuous label conveying path; furthermore, the area of ​​the support platform 26 is the label peeling area;

[0034] like Figure 4 As shown, the label transfer mechanism 3 includes a second robotic arm 31, and a peeling block 32 is fixedly connected to the movable end of the second robotic arm 31. The lower surface of the peeling block 32 is provided with air holes, and an air channel is provided inside. One end of the air channel is connected to the air holes, and the other end is connected to a vacuum generator (not shown in the figure). The vacuum generator causes a negative pressure to be generated on the lower surface of the peeling block.

[0035] The body of the second robotic arm 31 has at least forward, backward, left and right position movement directions so that the output end of the second robotic arm 31 can output to any point within the planar range of motion. The output end of the second robotic arm 31 has up, down and rotation functions so that the label can be taken out or put down by the peeling block 32 by "up and down" and the angle of the peeling block 32 can be adjusted by "rotation" so that the peeling block 32 fits the label.

[0036] like Figure 4 As shown, the pressing mechanism 4 includes a second slide 41 and a support plate with a movable end of the second slide. A pressing cylinder 43 with its movable end facing down and movable up and down is installed above the second slide 41 via a mounting bracket 42. A pressure plate 44 is fixedly connected to the movable end of the pressing cylinder 43. A pressing block corresponding to the cavity is provided below the pressure plate 44.

[0037] The automatic labeling device provided by this utility model works as follows: First, the operator places the products to be labeled into the cavity of the tray 12. The first slide 11 optimizes the feeding path; the feeding position is located away from the first robotic arm 13. The operator places the tray 12 carrying the labels onto the movable end of the first slide 11. Then, the first slide 11 drives the tray 12 closer to the first robotic arm 13. The glue spray head 15 installed on the first robotic arm 13 sprays glue onto the labeling area of ​​the products to be labeled. After the glue spraying is completed, the clamping device installed on the first robotic arm 13... Component 14 clamps the entire tray 12 and then transfers the tray 12 to the support plate of the pressing mechanism 4 via the body of the first machine 13; the second robotic arm 31 drives the peeling block 32 to move to the position of the support table 26, and uses the peeling block 32 to pick up the label and transfer it to the tray 12 located on the support plate, affixing the label to the surface of the product. Finally, the pressing cylinder 43 of the pressing mechanism 3 drives the pressing block 44 to press the label and the product together. The second slide 41 optimizes the feeding path. After the labeling is completed, the second slide 41 drives the tray 12 to move, so that the operator can take out the entire tray.

[0038] In one specific embodiment, the first robotic arm 13 and the second robotic arm 31 are Epson T3-B401S.

[0039] In one specific embodiment, such as Figure 2 As shown, the clamping assembly 14 includes a bidirectional cylinder and two clamping plates; the bidirectional cylinder is fixed to the movable end of the first robotic arm 13, and the clamping plates are fixed to the movable ends on both sides of the bidirectional cylinder, so that the two clamping plates can be driven to move closer or further apart by the bidirectional cylinder, and the glue spraying head 15 is fixed at one of the clamping plates.

[0040] In this embodiment, the tray 12 is clamped by bringing the clamps closer together, and the tray 12 is lowered by moving the clamps further apart.

[0041] In one specific embodiment, such as Figure 3 As shown, the fixing frame 21 is provided with a steering wheel 27. The output height of the steering wheel 27 is the same as the height of the support platform 26. The steering wheel 27 is located between the coil 22 and the support platform 26.

[0042] In this embodiment, after the label roll is drawn out from the roll reel 22, it is oriented by the directional wheel 27 and then passes through the support platform 26, so that the label roll remains horizontal in the area between the directional wheel 27 and the support platform 26 after being pulled out.

[0043] In one specific embodiment, such as Figure 5As shown, the support platform 26 includes a peeling plate 261, a reciprocating motor 262, a gear, a rack, a slide rail 263, and a connecting frame 264. The slide rail 263 is arranged on the fixed frame 21 along the conveying direction of the label roll. The connecting frame 264 is slidably connected to the slide rail 263. The reciprocating motor 262 is fixed inside the connecting frame 264. The peeling plate 261 is fixed above the connecting frame 264, and the height of the upper surface of the peeling plate 261 is flush with the output height of the steering wheel 27. The rack is fixed to the fixed frame 21, and the gear is sleeved on the movable end of the reciprocating motor 262. The gear and the rack mesh.

[0044] In this embodiment, the reciprocating motor 262 can rotate in both directions. After the reciprocating motor 262 is turned on, the peeling plate 261 can slide on the slide rail 263 through the cooperation of gears and racks, which can move back and forth in the path direction of the label roll, which is conducive to the peeling of the label. Specifically, when the peeling block 261 adsorbs the label, the peeling plate 261 moves in the opposite direction of the label roll conveying direction. At the same time, the drive motor 25 is turned on and rotates continuously, so that the label roll is in a taut state. Since the height of the peeling plate 261 is higher than the steering wheel 24, the label roll will gradually fall down as the peeling plate 261 moves after the peeling plate 261 loses support. Since the label is adsorbed, a process of gradually tearing the label from the label roll is formed. As the process continues, the remaining material of the torn label is finally collected by the receiving tray 23.

[0045] It can be seen that the automatic labeling equipment provided by this utility model can adapt to different products simply by changing the tray 12 and the corresponding pressure block, which greatly improves the diversified production needs.
