Description

Technical Field

[0001] This utility model relates to the field of lithium battery production equipment technology, specifically to a lithium battery coating machine with protective function. Background Technology

[0002] The prior art patent document CN217726104U discloses a lithium battery coating machine, including a worktable with an unwinding mechanism, a coating mechanism, and a winding mechanism. It also includes a drying mechanism, which comprises a hollow box with openings on both sides for accommodating lithium battery electrodes. The drying mechanism further includes a heating device and a heat-dissipating device mounted on the box. The heating device consists of a heating element and a cover. The heating element is housed within the cover, with an air inlet pipe connected to the upper end and an air outlet pipe connected to the lower end. The heat-dissipating device is hollow and has several air outlets, and is housed within the box. The air outlet of the air outlet pipe is connected to and extends through the bottom of the heat-dissipating device. The top of the box is an inverted cone, connected to and extending through the air inlet pipe. A fan is also installed inside the air outlet pipe, with the fan's airflow direction away from the cover. The air outlets are positioned relative to the interior of the box. The air vents are evenly distributed and rotate symmetrically around the center line of the housing. The cross-section of the vent is elongated, and the center line of the vent is not in the same plane as the center line of the housing, which allows the air inside the housing to rotate, accelerating air circulation and heat exchange. Both the inlet and outlet pipes are covered with heat-insulating material. The housing also includes an activated carbon adsorption device, which is installed on the inlet pipe. The airflow carries impurities and harmful gases to the activated carbon adsorption device, where they are absorbed. The unwinding mechanism includes an unwinding bracket fixedly installed on the worktable and an unwinding electrode located on one side of the unwinding bracket. The winding mechanism includes a winding bracket fixedly installed on the worktable and a winding electrode located on one side of the winding bracket. By continuously heating and circulating the air inside the housing, the overall internal temperature of the housing can be maintained stably, resulting in good baking effect on lithium battery electrodes and adsorption of impurities and harmful gases.

[0003] However, due to the poor automated coating capability of this lithium battery coating machine, it is impossible to quickly and conveniently automate the coating of lithium batteries as needed during actual use. It cannot meet different coating requirements well, and it is not easy for the lithium battery coating machine to sense nearby personnel, thus affecting the protective effect of the lithium battery coating machine. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor automated coating capabilities of existing lithium battery coating machines, which cannot meet different coating needs and have poor protective effects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The coating assembly includes a set of crossbeams symmetrically arranged on both sides of the supporting roller length, a movable plate slidably disposed between the two crossbeams, a coating tank mounted on the upper surface of the movable plate, a suspended electric push rod mounted on the bottom surface of the movable plate, and a coating plate fixedly connected to a push rod at the lower end of the suspended electric push rod. Several third electric push rods are mounted on the upper surface of the base below the crossbeams. A third push rod is movably connected to the upper end of each third electric push rod. The upper end of the third push rod is fixedly connected to the bottom surface of the crossbeam. Slide grooves are formed along the length direction on the opposite surfaces of the two crossbeams. Slider blocks that cooperate with the slide grooves are fixedly connected to both ends of the movable plate. A lead screw is rotatably connected in the slide groove. The slider is slidably connected in the slide groove. A lead screw nut that cooperates with the lead screw is fixedly connected to the end of the slider facing the lead screw. The lead screw nut is threaded onto the lead screw. A front-to-back moving motor is mounted on the outer wall of one end of the crossbeam. The drive shaft of the front-to-back moving motor is connected to the lead screw.

[0008] The feeding assembly includes a U-shaped feeding support frame installed on the upper surface of one end of the base, several feeding rollers rotatably connected to the feeding support frame, and a feeding motor installed on the feeding support frame for driving the feeding rollers to rotate.

[0009] The pulling assembly includes a set of pulling connecting frames installed on the upper surface of the base at the end away from the feeding assembly, a pulling roller rotatably connected between two pulling connecting frames, and a pulling motor installed on one of the pulling connecting frames;

A supporting roller is rotatably connected between the two supporting frames.

[0011] The base has a movable component on its bottom surface. The movable component includes four first electric push rods installed at the four corners of the base bottom surface. The lower end of each first electric push rod is movably connected to a first push rod. The lower end of each first push rod is fixedly connected to a swivel wheel. The swivel wheel is equipped with a brake.

[0012] A further improvement is that a supporting motor is installed on one of the supporting support frames, the drive shaft of the supporting motor is connected to the roller shaft of the supporting roller through a mounting plate, and the second infrared sensor is installed on the lower support plate.

[0018] The use of multiple feeding motors and feeding rollers in conjunction with pulling motors and pulling rollers facilitates the conveying of lithium battery coating raw materials;

[0019] The height of the supporting roller can be adjusted as needed. The second electric push rod extends and retracts, and the upper support plate rises and falls accordingly. The supporting roller and motor on the support plate rise and fall accordingly, thus achieving height adjustment to meet different coating requirements.

[0020] Driven by the third electric push rod, the third push rod extends and retracts, and the crossbeam rises and falls accordingly. The coating plate and coating tank on it also rise and fall accordingly, so as to freely adjust the gap between the coating plate and the support roller, which can meet different coating needs.

[0021] The forward and backward movement of the motor drives the lead screw to rotate, and the corresponding moving plate moves forward and backward along the chute, which in turn drives the coating plate and coating tank to move forward and backward, thereby realizing the position adjustment of the coating and further meeting different coating needs.

Then, using the first and second infrared sensors, the equipment stops when personnel are detected too close, improving overall safety. The coordinated use of the feeding motor, feeding roller, pulling motor, and pulling roller facilitates the conveying of lithium battery coating materials.

The raw materials are coated, and the height of the supporting rollers can be adjusted as needed. The second electric push rod extends and retracts, causing the upper support plate to rise and fall accordingly. This, in turn, raises and lowers the supporting rollers and the supporting motor on the upper support plate, thus adjusting the height to meet different coating requirements.
