Description

Technical Field

[0001] This utility model relates to the field of battery coating technology, specifically to an automatic battery coating device. Background Technology

[0002] To prevent short circuits in lithium batteries, the positive and negative electrodes are usually coated with adhesive to form an insulating barrier, preventing the positive and negative electrodes from contacting external conductors and reducing the risk of short circuits. However, traditional coating methods involve attaching adhesive tape to the surface, which often results in air bubbles during the coating process, greatly reducing the quality of the adhesive application and failing to meet usage requirements.

[0003] Based on the above problems, the existing patent publication number CN215771244U discloses an automatic coating device for lithium-ion batteries. By using a combination of a first electric telescopic rod, a pressing plate, a pressure block, and a connecting plate, the tape can be laid flat on the lithium-ion battery, making it highly automated and improving the working efficiency of the coating device. By setting up a horizontal moving mechanism, the pressing roller presses the tape onto the lithium-ion battery and scrapes off air bubbles on the tape, improving the quality of the coating.

[0004] However, when implementing the above-mentioned automatic encapsulation device for lithium-ion batteries, it was found that at least the following problems still exist: the encapsulation process is not continuous, and the next battery can only be encapsulated after the pick-up and put-down action is completed, which takes a lot of time, is not conducive to large-scale operation, and has low production efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic battery coating device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides an automatic battery coating device, comprising: a workbench; a coating machine installed on the workbench, the coating machine being capable of coating one side of the battery; and a transmission structure installed on the workbench, the transmission structure comprising two sets of belt conveyors, a working plate, a top plate, and a battery storage box. The top plate is fixedly installed on the workbench. The two sets of belt conveyors are horizontally arranged, one set of belt conveyors being installed on the workbench and the other set being installed on the top plate. Multiple working plates are evenly spaced and fixed on the belts of the two sets of belt conveyors. The working plates have insertion interfaces, the battery storage box is inserted into the insertion interfaces and fixed to the working plates, the opening of the battery storage box facing outwards, and the interval between the belts of the two sets of belt conveyors being greater than the width of the battery storage box.

[0007] Optionally, the bottom of the storage box is provided with an air hole, and the internal cavity of the storage box is adapted to the size of the lithium battery.

[0008] Optionally, a compressed air gun is fixed on the workbench, the compressed air gun is located inside the belt of the belt conveyor, and the compressed air gun faces the air hole of the storage tank.

[0009] Optionally, the workbench has a notch for a leakage pool, and an inclined guide plate is fixed at the notch for the leakage pool.

[0010] Optionally, both the workbench and the top plate are fixed with multiple spaced baffles, which restrict the belt of the belt conveyor from stretching inward.

[0011] Optionally, the distance between the two baffles located at the adhesive application point of the adhesive applicator is less than the width of the working plate.

[0012] Optionally, a mounting plate is bolted to the working plate, and the storage tank is bolted and fixed to the mounting plate.

[0013] Compared with the prior art, the present invention provides an automatic battery coating device, which has the following advantages: This invention uses a belt conveyor to move the working plate and the storage box, thereby sequentially transporting the batteries to the adhesive application area of ​​the adhesive applicator. This achieves continuous battery transport, and after one battery is adhesively applied, the next battery will be immediately transported to the adhesive application area without waiting for the pick-up and drop-off action. This greatly improves the efficiency of adhesive application, is conducive to large-scale operation, and solves the problem of discontinuous battery pick-up and drop-off during the traditional adhesive application process, which is not conducive to large-scale operation. This utility model allows air to circulate between the battery and the outside by setting air holes at the bottom of the battery storage box, making the battery more level when placed in the box and smoother when inserted. The internal cavity of the battery storage box is sized to fit tightly to the surface of the battery, providing better support for the battery when applying adhesive. This invention uses a compressed air gun to blow high-speed gas into the storage box through the air holes, which can slowly blow out the batteries in the storage box and reduce subsequent retrieval operations.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Please refer to Figures 1 to 6 According to an embodiment of this utility model, a technical solution is provided: an automatic battery coating device, comprising: a workbench 1; a coating machine 2, which is installed on the workbench 1 and can perform coating operations on one side of the battery; a transmission structure, which is installed on the workbench 1, the transmission structure including two sets of belt conveyors 3, working plates 4, a top plate 5, and a battery storage box 6, the top plate 5 being fixedly installed on the workbench 1, the two sets of belt conveyors being horizontally arranged, one set of belt conveyors 3 being installed on the workbench 1, and the other set of belt conveyors 3 being installed on the top plate 5, multiple working plates 4 being evenly spaced and fixed on the belts of the two sets of belt conveyors 3, the working plates 4 having insertion interfaces 7, the battery storage box 6 being inserted into the insertion interfaces 7 and fixed to the working plates 4, the opening of the battery storage box 6 facing outward, and the interval between the belts of the two sets of belt conveyors 3 being greater than the width of the battery storage box 6.

[0018] It should be noted that both the belt conveyor 3 and the adhesive applicator 2 are existing technologies. The working principle of the belt conveyor 3 is that the electric motor drives the drive drum to rotate through the reducer. The friction between the drive drum and the conveyor belt causes the belt to move. The material is placed on the belt and is transported to the designated location as the belt moves. Because the belt conveyor is horizontally set and is suitable for encapsulating small batteries, the small batteries and the battery storage box 6 will not tilt after the belt is tightened, which will affect the encapsulation. The adhesive applicator 2 guides the tape into the bonding position through the guide roller, and the electric push rod pushes the adhesive surface of the tape toward the battery, applying a certain pressure to the adhesive part so that the tape adheres to the surface of the battery.

[0019] The automatic battery coating device with the above structure has a battery storage box 6 inserted into and fixed in the insertion interface 7 of the work plate 4. The battery is placed in the battery storage box 6. When the belt conveyor 3 is running, it drives the work plate 4 and the battery storage box 6 to move, thereby transferring the batteries to the coating position of the coating machine 2 in sequence, realizing continuous battery transportation. After the coating of one battery is completed, the next battery will be transported to the coating position immediately without waiting for the pick-up and drop-off action, which greatly improves the coating efficiency, is conducive to large-scale operation, and solves the problem of discontinuous battery pick-up and drop-off in the traditional coating process, which is not conducive to large-scale operation.

[0020] The storage box 6 has an air hole 13 at the bottom. The internal cavity of the storage box 6 is adapted to the size of the lithium battery. The air hole 13 allows the air inside the storage box 6 to circulate with the outside, making the battery more level when it is placed in the storage box 6. At the same time, the battery is inserted into the storage box 6 more smoothly. The adapted size of the internal cavity of the storage box 6 allows the storage box 6 to fit tightly with the surface of the battery, and can better support the battery when applying adhesive.

[0021] A compressed air gun 8 is fixed on the workbench 1. The compressed air gun 8 is located inside the belt of the belt conveyor 3 and faces the air hole 13 of the battery storage box 6. After the battery is put in, it is difficult to take it out. After the adhesive is applied, since the internal cavity of the battery storage box 6 is adapted to the size of the battery, when the compressed air gun 8 blows the gas into the air hole 13, the battery in the battery storage box 6 can be slowly blown out, reducing subsequent retrieval operations.

[0022] The workbench 1 has a battery draining notch 9, and an inclined guide plate 10 is fixed at the battery draining notch 9. When the battery storage box 6 moves to the position of the battery draining notch 9 with the belt conveyor 3, the compressed air gun 8 blows the battery out of the battery storage box 6. Due to the existence of the battery draining notch 9, the battery will fall onto the guide plate 10 under the action of gravity. The inclined guide plate 10 can guide the battery storage box 6 to slide down in a specific direction, which makes it easy to collect the battery to a designated position and facilitate subsequent battery processing.

[0023] Multiple spaced baffles 11 are fixed on both the workbench 1 and the top plate 5. The baffles 11 restrict the belt of the belt conveyor 3 from stretching inward. The baffles 11 provide lateral constraints to the belt, keeping it on the normal running track and ensuring that the material can be stably transported on the belt, avoiding material falling or affecting subsequent processing due to belt deviation.

[0024] The two baffles 11 located at the adhesive application point of the adhesive applicator 2 are spaced apart by less than the width of the working plate 4. When the working plate 4 is transported to the adhesive application point on the belt conveyor 3, the baffles 11 spaced apart can restrict the backward movement of the working plate 4, so that it stops accurately at the adhesive application position, ensuring the accuracy and consistency of the adhesive application position and improving the adhesive application quality.

[0025] A mounting plate 12 is bolted to the working plate 4, and the storage box 6 is bolted and fixed to the mounting plate 12. During installation, the mounting plate 12 can be quickly fixed to the working plate 4 using bolts and nuts, and then the storage box 6 can be fixed to the mounting plate 12. When it is necessary to replace, repair or clean the storage box 6, the bolts can be easily unscrewed to remove the storage box 6 from the mounting plate 12. The operation is simple and saves time and labor costs.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
