Description

Technical Field

[0001] The utility model relates to the technical field of product labeling, in particular to a double-station automatic labeling machine. Background Art

[0002] In the production process of some products, they need to be labeled before they can be sold. Labeling has become an indispensable part of the process. Therefore, the labeling efficiency also affects the overall production efficiency of the product. In order to avoid the disadvantages of low labeling efficiency caused by manual labeling, labeling machines are manufactured.

[0003] The labeling machine is a device that sticks rolls of self-adhesive paper labels (paper or aluminum foil) on PCBs, products or specified packaging. The main working mechanism of the labeling machine consists of a label supply device, a label taking device, a printing device, a gluing device and a chain device.

[0004] However, the existing labeling machines not only have poor labeling stability, are easy to fall off and have low labeling accuracy, but also have only one labeling station. In the actual operation process, the waiting time of the staff is increased, thereby reducing the labeling efficiency.

[0005] Therefore, it is necessary to provide a double-station automatic labeling machine to solve the above problems. Utility Model Content

[0006] In order to overcome the above shortcomings, the purpose of the utility model is to provide a double-station automatic labeling machine, in which the double stations simultaneously or alternately transport products to be labeled, thereby improving product labeling efficiency and reducing the labor intensity of staff.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is: a double-station automatic labeling machine, including a labeling machine frame, a product conveying line with two groups of product placement positions to be labeled arranged in parallel, a material picking mechanism and a line encoder; the product conveying line transfers the products to be labeled through the visual monitoring mechanism and the labeling position in sequence, the material picking mechanism includes a mechanical arm vertically suspended on the labeling machine frame, a label suction mechanism is provided at the material picking end of the mechanical arm, and multiple groups of label suction components on the label suction mechanism can attach labels to the products to be labeled, and the line encoder is arranged on the labeling machine frame and corresponds to the position of the material picking mechanism.

[0008] The product conveyor line can transfer multiple products to be labeled at one time. The visual monitoring mechanism is used to determine the number of products to be labeled, their precise positions, and the precise parameters of the labeling position on a single product to be labeled, and transmit the above parameters to the robotic arm. The line encoder can calculate the data and distance of the product conveyor line movement, and also transmit the above data to the robotic arm. The label suction mechanism on the robotic arm absorbs the label and moves to the labeling position of the first product to be labeled calculated by the line encoder, and performs rapid labeling, and then moves to the labeling position of the second product to be labeled according to the above algorithm, and performs rapid labeling. The product conveyor line does not need to be stopped for labeling operations, which can further improve the product labeling efficiency. At the same time, the two product placement positions to be labeled are alternately labeled, which also improves the labeling work efficiency.

[0009] Furthermore, each group of product placement positions to be labeled is provided with a plurality of position limiting carriers along the length direction of the product conveyor line, and two position limiting carriers adjacently arranged along the width direction of the product conveyor line are arranged in parallel or staggered positions. The position limiting carriers match the shape of the product to be labeled, and can ensure that the position of the labeled product will not shift during the movement of the product conveyor line, thereby ensuring the accuracy of subsequent automatic labeling.

[0010] Furthermore, the visual monitoring mechanism includes a monitoring camera and a support plate for supporting the monitoring camera, and the top of the support plate is surrounded by protective plates, and the bottoms of the two protective plates arranged perpendicular to the conveying direction of the product conveying line are respectively connected to the diffusion plate through an angle adjustment component. The monitoring camera is used to monitor the number and position of the products to be labeled passing through it, as well as the precise parameters of the labeling position on the products to be labeled, and can accurately transmit the above data to the robot arm, thereby ensuring the position accuracy of the subsequent automatic labeling of the label suction component.

[0011] The angle adjustment component can adjust the position of the diffuser plate on the protective plate, guide the light for the monitoring camera, and change different angles according to the positions where labels are required on different products to be labeled, so that the light emitted by the light source is more uniform, thereby ensuring more accurate positioning of the monitoring camera.

[0012] Furthermore, the angle adjustment mechanism includes waist-shaped holes and limit screws symmetrically arranged on the protective plate, and the limit screws pass through the waist-shaped holes and are threadedly connected to the jacks provided on the diffuser plate. The waist-shaped holes are arranged in an arc shape, so as to meet the adjustment of the angles between the diffusers arranged oppositely, and ensure that the light is more uniform.

[0013] Furthermore, the visual monitoring mechanism is installed on the side of the labeling machine frame through a mounting bracket and is located at the loading end of the product conveyor line. The mounting bracket can support the visual monitoring mechanism, and the mounting bracket can timely monitor the position and quantity of the products to be labeled that enter the labeling position.

[0014] Furthermore, the label suction mechanism also includes a label suction support frame, and a plurality of label suction components are arranged around the label suction support frame. The label suction component includes a telescopic driving member vertically arranged on the label suction support frame, and a mounting plate is arranged at the driving end of the telescopic driving member, and a vacuum suction plate for adsorbing labels is arranged on the lower surface of the mounting plate. The plurality of telescopic driving members are adapted to products with different labeling requirements, and the plurality of telescopic driving members work independently without interfering with each other, and are more applicable.

It should be noted that a plurality of through holes are also provided on the vacuum suction plate.

[0016] Furthermore, the visual monitoring mechanism, the line encoder and the product conveying line are all electrically connected to the material taking mechanism.

The mounting bracket 4 can support the visual monitoring mechanism 3, and the mounting bracket 4 can timely monitor the position and quantity of the products to be labeled that enter the labeling position on the product conveying line 2.

[0039] Working principle: The label suction component on the robot arm takes the label at the label stripping machine, and the visual monitoring camera detects the products to be labeled placed on the product conveyor line to determine the number of products to be labeled. Position and identify the labeling position, and transmit all the above position parameters to the robot arm. The line encoder calculates the moving speed of the product conveyor line and the distance of the products on it, and transmits the data to the robot arm. The robot arm calculates the labeling position on the first product to be labeled according to the algorithm and moves to the labeling place for rapid labeling, and then moves to the labeling position on the second product to be labeled according to the algorithm and moves to the labeling place for rapid labeling. Repeat the above operation.
