Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a labeling device. Background Art

[0002] Currently, after battery production is completed, it is usually necessary to attach labels to the surface of the battery. Existing labeling equipment mainly uses robots to take labels, and then the robot adheres the labels directly to the battery according to a set path. However, since the labels are set on the material belt, the labels on the material belt may be offset, resulting in the relative position of the label and the robot changing each time labeling is performed, resulting in inconsistent positions of the labels on the battery, and poor labeling accuracy and consistency. In addition, before labeling, the surface of the battery may be dirty, and direct labeling can easily affect the appearance of the product. Therefore, it is necessary to distinguish dirty batteries, but existing equipment cannot effectively distinguish dirty batteries, resulting in them flowing into the next process after labeling, affecting the final quality of the product. Utility Model Content

[0003] In view of this, in order to solve the problems in the prior art, the utility model provides a labeling device with high labeling accuracy and capable of performing surface detection.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A labeling device comprises: a machine platform; a conveying mechanism provided on the machine platform, the conveying mechanism comprising a linear module and a mounting carrier mounted on the linear module; a surface detection mechanism provided on one side of the conveying mechanism, the surface detection mechanism comprising a detection lens and a first light supply unit arranged in sequence up and down, the first light supply unit comprising an annular light source and a first strip light source arranged on the side of the annular light source, the first strip light source being arranged at an angle; a labeling mechanism provided on one side of the conveying mechanism, the labeling mechanism comprising a feeding device, a material picking robot and a positioning device, the positioning device comprising a second light supply unit and a positioning lens arranged in sequence up and down.

[0006] In the above technical solution, a labeling device is provided for labeling the surface of a battery. The battery to be labeled is placed on a mounting carrier. The mounting carrier reaches the surface detection mechanism and the labeling mechanism in succession under the drive of the linear module. When arriving at the surface detection mechanism, the detection lens takes a picture of the battery with the assistance of the first light supply unit to perform surface detection to check whether there is dirt on the surface of the battery. The first light supply unit includes a ring light source and a first strip light source arranged obliquely. The light outlet of the first strip light source is obliquely downward toward the bottom of the ring light source. The ring light source is used to illuminate the front of the battery. A bar light source is used to illuminate the side of the battery to simultaneously detect the front and side of the battery to ensure that the battery surface is clean. After the surface inspection passes, the battery arrives at the labeling mechanism with the linear module, and the material strip with the label is installed on the feeding device. The feeding device discharges the label, and the picking robot removes the label from the feeding device and moves it to the top of the positioning device. The positioning lens, with the assistance of the second light supply unit, takes a picture of the label for positioning detection, determines the position deviation of the label and transmits the data to the picking robot. Then the picking robot accurately sticks the label on the battery based on the offset obtained by positioning.

[0007] Furthermore, a hollow portion is provided at the center of the annular light source, and the detection lens is located directly above the hollow portion.

[0008] In the above technical solution, the hollow part is located in the center of the annular light source. When performing surface inspection, the battery is located directly below the hollow part of the annular light source. The line of sight of the inspection lens passes through the hollow part and falls on the battery below to ensure that the brightness and darkness of each area of ​​the image captured by the lens are uniform.

[0009] Furthermore, the surface detection mechanism further includes a mounting support, the mounting support is provided with a first guide rail arranged along the vertical direction, and the detection lens and the annular light source are both slidably mounted on the first guide rail.

[0011] Furthermore, the positioning device includes a mounting plate, a second guide rail arranged along the vertical direction is provided on the mounting plate, and the second light supply unit and the positioning lens are both slidably mounted on the second guide rail.

[0012] In the above technical solution, the second light supply unit and the positioning lens can slide along the second guide rail, so that the height of the second light supply unit and the positioning lens can be adjusted to meet focusing needs or other requirements.

[0013] Furthermore, the second light supply unit includes a sliding block slidably mounted on the second guide rail, a slide provided on the sliding block, and a connecting rod slidably mounted in the slide, wherein a slide groove is provided on the connecting rod, and a second strip light source is slidably mounted in the slide groove.

[0014] In the above technical solution, the slide is horizontally arranged, one end of the connecting rod is slidably installed in the slide, and the direction of the slide groove is perpendicular to the direction of the slide. Therefore, the directions of the second guide rail, the slide and the slide groove are perpendicular to each other, so that the spatial position of the second strip light source can be flexibly adjusted.

[0015] Furthermore, the output end of the material retrieving robot is connected to a connecting block, a material retrieving driving component is installed on the connecting block, and the output end of the material retrieving driving component is connected to a suction nozzle.

[0016] In the above technical solution, the suction nozzle is used to suck the labels on the label material belt, and the material picking drive is used to drive the suction nozzle to rise and fall, so that the suction nozzle can pick up the labels.

[0017] Furthermore, the feeding device includes a feeding plate, a feeding wheel and a plurality of guide rollers.

[0018] In the above technical solution, the unloading wheel is used to install the label material strip, and the material strip is unloaded by rotating. After the unloaded material strip is guided by the guide roller, a part of it is laid flat on the picking plate. The picking plate is used to provide a force surface to keep the label in a horizontal state, which is convenient for the suction nozzle to pick up the material.

[0019] Furthermore, the mounting carrier includes a carrier plate and a fixture, the carrier plate is connected to the output end of the linear module, and the fixture is mounted on the carrier plate.

[0020] In the above technical solution, the fixture is used to clamp and fix the battery, and the linear module drives the fixture to move by driving the carrier plate.

[0021] Furthermore, the machine platform is also provided with a clamping mechanism, which is arranged on one side of the linear module. The clamping mechanism includes a clamping drive component and a top block connected to the output end of the clamping drive component.

[0022] In the above technical solution, the clamping mechanism is used to open the clamp, which is a press-type structure. The battery is manually loaded into the clamp and the clamp is buckled. When the battery is labeled, it is moved to the clamping mechanism driven by the linear module. The clamping drive drives the top block to move toward the clamp. The top block contacts the press-type switch on the clamp to open the clamp, and then the staff takes out the battery in the clamp.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] This application can realize the automatic labeling of battery surface, with high degree of automation and simple operation;

[0025] This application uses a surface inspection mechanism to inspect the battery surface to ensure that the battery surface is free of dirt before labeling. The surface inspection mechanism is equipped with a ring light source and a strip light source, which are used to illuminate the labeling surface and side of the battery respectively, so that the image obtained by the camera has uniform brightness and darkness, effectively improving the accuracy of the inspection and enhancing the reliability of the equipment.

[0026] This application is equipped with a positioning device. After the material-picking robot picks up the label, it first moves to the positioning device for visual positioning.

A connecting rod 4313 is slidably mounted in the slide 4312. The connecting rod 4313 is L-shaped and has a slide groove 4314 on it. The second strip light source 4315 is slidably mounted in the slide groove 4314. The directions of the second guide rail 45, the slide 4312 and the slide groove 4314 are perpendicular to each other, so that the spatial position of the second strip light source 4315 can be flexibly adjusted.

[0053] Specifically, two second strip light sources 4315 are provided, and both second strip light sources 4315 are tilted, with their light outlets obliquely pointing upward toward the position above the positioning lens 432.
