Description

Technical Field

[0001] The present invention relates to the field of lithium ion battery monomer processing, and in particular to a lithium ion battery monomer sealing device and a sealing processing method. Background Art

[0002] Lithium-ion battery cells, composed of electrodes and electrolytes, are the basic units of battery packs and are called single batteries. Lithium-ion batteries have developed rapidly due to their light weight, high capacity, high operating voltage, long service life and zero pollution. Their global sales have exceeded the total of nickel-metal hydride and nickel-cadmium batteries.

[0003] During the processing of lithium-ion battery cells, the difficulty in controlling the sealing is one of the technical difficulties. If there is a slight leakage, the lithium-ion battery cells will cause bloating, leakage, and even failure during use and storage. Summary of the invention

[0009] Preferably, the coating assembly includes a quantitative discharging mechanism, a cleaning plate, a second air duct and a cleaning nozzle; a cleaning plate is provided at the lower end of the discharging pipe of the quantitative discharging mechanism; a lifting mechanism is provided at the upper end of the quantitative discharging mechanism; a cleaning nozzle is provided at the lower end of the cleaning plate; and a second air duct is provided at the left end of the cleaning nozzle.

[0010] Preferably, the curing assembly includes a lifting frame, a telescopic cylinder, a pressing plate, a third air duct and an accelerated curing air outlet; a left-right symmetrical pressing plate is arranged on the inner side of the lifting frame operating slot; a telescopic cylinder for controlling the pressing plate to synchronously extend and retract is arranged on the outer side of the pressing plate; an accelerated curing air outlet is arranged on the upper end of the pressing plate; and a third air duct is arranged on the left end of the accelerated curing air outlet.

[0011] Preferably, the detection component includes a support table, a servo motor, a linkage rod, a limit slide groove, a limit slider and an industrial suction cup; a servo motor is arranged at the lower end of the support table; and the output end of the servo motor is connected to one end of the linkage rod.

[0012] Preferably, a limit slider is installed at the other end of the linkage rod; a long limit slide groove is opened at the upper end of the support platform; the limit slide groove and the limit slider are slidably connected; an industrial suction cup for adsorbing the top of the lithium-ion battery cell is installed at the lower end of the limit slider.

[0013] A lithium-ion battery monomer sealing processing method comprises the following steps:

[0014] S1: Transfer, the staff transfers the lithium-ion battery monomer to the transmission mechanism. The upper end of the transmission mechanism is provided with 8 to 10 positioning components. When the lithium-ion battery monomer is placed in the positioning plate of the placement seat, the drive motor is started through a predetermined program. The drive motor controls the bidirectional screw and the threaded sleeve to drive the upper clamping plate to move inward synchronously. The clamping plate with an anti-slip pad at the clamping end clamps symmetrically from the outer side of the lithium-ion battery monomer to the lower end, and the lithium-ion battery monomer is stably positioned;

[0015] S2: Cleaning treatment. The lithium-ion battery monomer moves with the transmission mechanism and needs to stay for 10 to 15 seconds when entering the dust-free treatment component. The air intake fan introduces the air from the outside that has passed through the multi-layer filter structure. The impurities and dust in the air have been filtered out. The clean air is input into the main pipeline and transported to the isolation room through the first air duct. The lithium-ion battery monomer located in the blowing chamber is cleaned by the air flow. After the treatment, the lithium-ion battery monomer must meet the standard of dust-free and debris-free surface. The impurities and dust blown away fall out from the transmission mechanism with holes;

[0016] S3: Sealing material coating. Next, the lithium-ion battery cell reaches the lower end of the coating assembly and stays there for 10 to 15 seconds. The quantitative discharging mechanism descends, and the discharging pipe is located at the connecting edge of the upper circular surface of the lithium-ion battery cell. The rotating motor of the positioning assembly drives the lithium-ion battery cell to rotate. The discharging pipe of the quantitative discharging mechanism coats an appropriate amount of sealing material on the sealing position of the battery cell. After the coating is completed, the quantitative discharging mechanism rises. During the rising process, the discharging pipe of the quantitative discharging mechanism needs to pass through the cleaning plate. The cleaning plate scrapes off the excess sealing material on the outside of the discharging pipe. Then, the second air duct inputs high-pressure airflow to the cleaning nozzle to blow away the dried sealing material at the lower end of the cleaning plate to avoid affecting the quality of the next sealing material coating.

[0017] S4: Accelerate curing and pressing. When the lithium-ion battery cell moves to the curing assembly, it stays for 10 to 15 seconds, and the lifting frame moves down. The operating slot of the lifting frame frames the lithium-ion battery cell. Two symmetrical telescopic cylinders drive the arc-shaped pressing plates to clamp the outer side of the sealed connection of the lithium-ion battery cell with appropriate force. The rotating motor of the positioning assembly drives the lithium-ion battery cell to rotate. The pressing plates gradually increase the pressing force to flatten and tighten the sealed connection of the lithium-ion battery cell. At the same time, the accelerated curing air outlet at the top conveys the clean air input from the third air duct downward to accelerate the molding speed of the sealing material, ensuring that the seal is tight and the connection is firm.

[0018] S5: Check the sealing performance. After the above steps are completed, the lithium-ion battery cell enters the final inspection component. The positioning component releases the clamping of the lithium-ion battery cell. The industrial suction cup sucks and rises from the top of the lithium-ion battery cell. The servo motor controls the linkage rod to drive the limit slider to reciprocate in the limit slide groove, driving the lithium-ion battery cell at the lower end to shake continuously. Through this test, the staff inspects the appearance of the lithium-ion battery cell to ensure that there is no leakage and the sealing quality meets the requirements. The lithium-ion battery cells that meet the requirements are transported to the next process.

[0019] Beneficial effects of the present invention:

[0020] The present invention drives the lithium ion battery cell stably clamped by the positioning component to move through a transmission mechanism, and sequentially passes through the positioning component, the dust-free treatment component, the coating component, the curing component and the detection component for processing, thereby greatly improving the degree of automation of the sealing processing and improving the efficiency of the sealing processing. The dust-free treatment component cleans the surface of the lithium ion battery cell to meet the standard of dust-free and debris-free surface to ensure that the subsequent sealing effect is not affected. The coating component coats the sealing position of the upper end of the lithium ion battery cell with sealing material, and cleans the discharge pipe in time to make the coating process more standardized. The curing component presses the outer side of the connection of the lithium ion battery cell, and at the same time conveys airflow downward to accelerate the molding speed of the sealing material, ensure that the seal is tight and the connection is firm, and finally the detection component drives the lithium ion battery cell to be continuously shaken to ensure that there is no leakage and that the sealing quality meets the requirements.

[0036] According to another aspect of the present invention, there is provided a lithium ion battery monomer sealing device and a sealing processing method, comprising the following steps:

[0037] S1: Transport, the staff transports the lithium-ion battery monomer to the transmission mechanism 1. The upper end of the transmission mechanism 1 is provided with 8 to 10 positioning components 2. When the lithium-ion battery monomer is placed in the positioning plate of the placement seat 203, the drive motor 204 is started through a predetermined program. The drive motor 204 controls the bidirectional screw and the threaded sleeve 205 to drive the upper clamping plate 206 to move inward synchronously. The clamping plate 206 with an anti-slip pad 207 at the clamping end symmetrically clamps the lithium-ion battery monomer from the outer side of the lithium-ion battery monomer near the lower end, and the lithium-ion battery monomer is stably positioned;

[0038] S2: Cleaning treatment. The lithium-ion battery monomer moves with the transmission mechanism 1 and needs to stay for 10 to 15 seconds when entering the dust-free treatment component 3. The air intake fan 302 introduces the air from the outside through the multi-layer filter structure 303. The impurities and dust in the air have been filtered out. The clean air is input into the main pipeline 301 and transported to the isolation room 304 through the first air duct 305. The lithium-ion battery monomer located in the blowing chamber 306 is cleaned by the air flow. After the treatment, the lithium-ion battery monomer must meet the standard of dust-free and debris-free surface. The impurities and dust blown away fall out from the transmission mechanism 1 with holes;

[0039] S3: Sealing material coating. Next, the lithium-ion battery cell reaches the lower end of the coating component 4 and stays there for 10 to 15 seconds. The quantitative discharging mechanism 401 descends, and the discharging pipe is located at the connecting edge of the upper circular surface of the lithium-ion battery cell. The rotating motor 202 of the positioning component 2 drives the lithium-ion battery cell to rotate. The discharging pipe of the quantitative discharging mechanism 401 coats an appropriate amount of sealing material on the sealing position of the battery cell. After the coating is completed, the quantitative discharging mechanism 401 rises. During the rising process, the discharging pipe of the quantitative discharging mechanism 401 needs to pass through the cleaning plate 402. The cleaning plate 402 scrapes off the excess sealing material on the outside of the discharging pipe. Then, the second air duct 403 inputs a high-pressure airflow to the cleaning nozzle 404 to blow off the dried sealing material at the lower end of the cleaning plate 402 to avoid affecting the quality of the next sealing material coating.

[0040] S4: Accelerate curing and pressing. When the lithium-ion battery cell moves to the curing component 5, it stays for 10 to 15 seconds. The lifting frame 501 moves down. The operating slot of the lifting frame 501 frames the lithium-ion battery cell. Two symmetrical telescopic cylinders 502 drive the arc-shaped pressing plates 503 to clamp the outer side of the sealed connection of the lithium-ion battery cell with appropriate force. The rotating motor 202 of the positioning component 2 drives the lithium-ion battery cell to rotate. The pressing plates 503 gradually increase the pressing force to flatten and tighten the sealed connection of the lithium-ion battery cell. At the same time, the accelerated curing air outlet 505 at the top conveys the clean air input from the third air duct 504 downward to accelerate the molding speed of the sealing material and ensure that the seal is tight and the connection is firm.

[0041] S5: Check the sealing performance. After the above steps are completed, the lithium-ion battery cell enters the final inspection component 6. The positioning component 2 releases the clamping of the lithium-ion battery cell. The industrial suction cup 606 sucks and rises from the top of the lithium-ion battery cell. The servo motor 602 controls the linkage rod 603 to drive the limit slider 605 to reciprocate in the limit slide groove 604, driving the lithium-ion battery cell at the lower end to shake continuously. Through this test, the staff inspects the appearance of the lithium-ion battery cell to ensure that there is no leakage and the sealing quality meets the requirements. The lithium-ion battery cells that meet the requirements are transported to the next process.

[0042] Through the above steps, the lithium-ion battery cell stably clamped by the positioning component 2 is driven to move by the transmission mechanism 1, and is processed by the positioning component 2, the dust-free treatment component 3, the coating component 4, the curing component 5 and the detection component 6 in sequence, which greatly improves the degree of automation of the sealing process and the efficiency of the sealing process. The surface of the lithium-ion battery cell is cleaned by the dust-free treatment component 3 to meet the standard of dust-free and debris-free surface to ensure that the subsequent sealing effect is not affected. The sealing material is coated on the sealing position of the upper end of the lithium-ion battery cell by the coating component 4, and the discharge pipe is cleaned in time to make the coating process more standardized. The outer side of the connection of the lithium-ion battery cell is pressed by the curing component 5, and the air flow is conveyed downward at the same time to accelerate the molding speed of the sealing material, ensure that the seal is tight and the connection is firm, and finally the lithium-ion battery cell is driven to shake continuously by the detection component 6 to ensure that there is no leakage.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.

At the same time, the accelerated curing air outlet (505) at the top conveys the clean air input from the third air duct (504) downward to accelerate the molding speed of the sealing material and ensure that the sealing is tight and the connection is firm. S5: Checking the sealing performance. After the above steps are completed, the lithium-ion battery cell enters the final inspection component (6). The positioning component (2) releases the grip on the lithium-ion battery cell. The industrial suction cup (606) sucks and rises from the top of the lithium-ion battery cell. The servo motor (602) controls the linkage rod (603) to drive the limit slider (605) to reciprocate in the limit slide groove (604), driving the lithium-ion battery cell at the lower end to shake continuously. Through this test, the staff inspects the appearance of the lithium-ion battery cell to ensure that there is no leakage and the sealing quality meets the requirements. The lithium-ion battery cell that meets the requirements is transported to the next process.
