Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to a glue coating device and method. Background Art

[0002] In the production and manufacturing process of lithium batteries, gluing is an important process. The current existing production line gluing method is generally for a gluing robot to apply glue along a predetermined trajectory. For example, the patent document with publication number CN109148906A discloses a fully automatic assembly line for lithium batteries, including a gluing process. The gluing process includes a three-axis robotic arm installed on a frame and corresponding to a conveying device, and a gluing device is installed on the three-axis robotic arm. In actual production, the gluing trajectory will be offset due to reasons such as the vibration of the production line equipment causing the glue gun head to swing. The existing gluing device is unable to detect and correct the offset of the gluing trajectory, resulting in inconsistent gluing trajectories, faults in the gluing trajectory, or the formation of irregular S-shaped gluing trajectories, which in turn leads to problems such as uneven assembly of the later lithium battery modules or local degumming. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to detect and correct the offset of the gluing track.

[0004] The present invention solves the above technical problems by the following technical means: a gluing device, comprising a deviation-correcting component, a gluing component, a lifting component and a gluing conveying line;

[0005] The gluing station of the gluing conveyor line is provided with a blocking mechanism, a gluing assembly is provided above the gluing station, and a lifting assembly is provided below the gluing station;

[0006] The correction assembly includes an offset sensor, a movable plate, a base plate and a driving mechanism. The base plate is installed on the lifting end of the jacking assembly. The movable plate is movably fitted on the base plate. The driving mechanism can drive the movable plate to move relative to the base plate along the width direction of the glue coating conveyor line. The movable plate is provided with an offset sensor.

[0007] The device detects the offset direction and offset amount of the gluing end of the gluing component during the gluing process through an offset sensor, and realizes gluing correction by driving the movable plate through a driving mechanism. It cleverly solves the problem of gluing trajectory offset caused by equipment vibration and other reasons during the gluing process, reduces the unqualified rate of product assembly, improves the yield rate of gluing and rear-stage module box assembly, greatly increases the qualified rate of products, and reduces the cost waste caused by manufacturing.

[0008] As an optimized technical solution, the gluing assembly includes a rubber cylinder assembly, a rubber cylinder mounting plate, a ranging sensor and a gluing robot. The rubber cylinder mounting plate is installed on the moving end of the gluing robot, and the rubber cylinder assembly and the ranging sensor are both installed on the rubber cylinder mounting plate.

[0009] The distance measuring sensor is used to detect the height of the gluing end of the gluing component during the gluing process, so that the gluing height can be adjusted in real time to make the gluing more uniform.

[0010] As an optimized technical solution, the glue coating assembly further includes a glue cylinder fixing support, and the upper part and the middle part of the glue cylinder assembly are fixedly connected to the glue cylinder mounting plate through the glue cylinder fixing support respectively.

[0011] The multiple fixings can reduce the swing of the rubber cartridge assembly, thereby reducing the deviation of the rubber application end.

[0012] As an optimized technical solution, the jacking assembly includes a jacking plate, a fixed plate and a cylinder. The fixed plate is fixedly connected to the glue conveyor line, the cylinder is fixedly connected to the fixed plate and its moving end is located above the fixed plate, and the jacking plate is installed at the moving end of the cylinder.

[0013] The cylinder can drive the correction component to rise and fall. When the correction component is raised, the material can be separated from the gluing conveyor line for gluing. When the correction component is lowered, the material can be returned to the gluing conveyor line for further transportation.

[0014] As an optimized technical solution, the lifting assembly also includes a guide shaft, a linear bearing and a connecting plate; the linear bearings are provided in two groups, and the two groups of linear bearings are respectively installed on the fixed plate at positions on both sides of the cylinder; the two groups of linear bearings are respectively slidably fitted with guide shafts, the upper ends of the two groups of guide shafts are respectively fixedly connected to the lifting plate, and the lower ends of the two groups of guide shafts are respectively fixedly connected to the connecting plate.

[0015] The guide shaft can slide up and down in the linear bearing as the cylinder drives the lifting plate to move, providing guidance and positioning. The arrangement of multiple sets of guide shafts and connecting plates can prevent the guide shaft from tilting, making the guiding effect more stable.

[0016] As an optimized technical solution, the correction component also includes a sensor bracket, which is installed on the movable plate. The sensor bracket is provided with multiple groups of offset sensors, and the multiple groups of offset sensors are arranged in a row along the moving direction of the movable plate.

[0017] The offset sensors are installed through the sensor bracket, and the positions of multiple groups of offset sensors relative to the moving plate are fixed so that the monitoring range of the offset sensors corresponds to the designed gluing track.

[0018] As an optimized technical solution, the correction component also includes a slide rail slider assembly, and slide rail slider assemblies are respectively installed on the front and rear sides of the base plate along the movement direction of the glue conveyor line, and the movable plate is slidably fitted on the base plate through the slide rail slider assembly.

[0019] The slide rail and slider assembly plays a guiding role, making the movement of the moving plate more stable.

[0020] As an optimized technical solution, a positioning structure is provided on the top surface of the movable plate.

[0021] The positioning structure can prevent the incoming material position from shifting.

[0022] As an optimized technical solution, the gluing device further includes a feeding trolley, which includes an AGV trolley and a lifting mechanism arranged on the AGV trolley.

[0023] The AGV can travel along the specified navigation path, and the lifting mechanism can lift and drop materials to remove materials from the rack and drop them onto the gluing conveyor line, achieving high work efficiency.

[0024] A gluing method, using the gluing device, comprises the following steps:

[0025] S1, feeding materials to the glue coating conveying line;

[0026] S2, the gluing conveyor line transports the material to the gluing station and blocks and positions it through the blocking mechanism;

[0027] S3, the lifting component lifts the deviation-correcting component to separate the material from the gluing conveyor line;

[0028] S4, the gluing component applies glue to the material;

[0029] S5. When the gluing end position of the gluing component deviates, the offset sensor obtains the gluing offset signal in real time, and feeds it back to the driving mechanism to drive the moving plate to move in the opposite direction relative to the offset direction in real time to correct the offset;

[0030] S6. After the gluing is completed, the lifting assembly lowers the deviation-correcting assembly, the blocking mechanism is released, and the gluing conveyor line transports the glued material to the next station.

[0031] This method uses an offset sensor to detect the offset direction and offset amount of the gluing end of the gluing component during the gluing process, and drives the moving plate to move through the driving mechanism to achieve gluing correction. It cleverly solves the problem of gluing trajectory offset caused by equipment vibration and other reasons during the gluing process, reduces the unqualified rate of product assembly, improves the yield rate of gluing and rear-stage module box assembly, greatly increases the qualified rate of products, and reduces the cost waste caused by manufacturing.
