Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of negative pressure cup cleaning equipment, specifically to an automatic drying mechanism for negative pressure cups. Background Technology
[0002] During the battery formation process, gas is continuously generated. This gas carries the electrolyte from the battery into the formation negative pressure cup. When formation is complete, the electrolyte in the negative pressure cup flows back into the battery. However, in some channels where the vacuum is not properly blocked, the electrolyte cannot flow back completely. The electrolyte remaining in the negative pressure cup quickly weathers and crystallizes. This crystallization can block the channels for drawing negative pressure from the battery, affecting its use in the next negative pressure formation. Therefore, the negative pressure cup needs to be cleaned. In actual production, the cleaned negative pressure cup needs to be dried.
[0003] Currently, the main cleaning technologies include cleaning with DMC (dimethyl carbonate) solution and hot water. DMC solution can effectively dissolve electrolyte residues, and due to its volatile properties, it can air dry after cleaning. However, it is expensive, and the volatile gases are harmful to human health. Hot water and other non-volatile cleaning solvents require the negative pressure components to be left to stand in a drying room for a long time after cleaning to ensure complete evaporation of moisture. The drying process is relatively time-consuming and inefficient. In addition, since the drying process may adversely affect the airtightness of the negative pressure cup, the airtightness of the negative pressure cup needs to be tested after drying. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention proposes an automatic drying mechanism for negative pressure cups. This mechanism is highly automated and intelligent, enabling simultaneous drying of multiple negative pressure cups and subsequent airtightness testing, thereby significantly improving the efficiency and quality of negative pressure cup drying.
[0005] To achieve the above technical solution, this utility model provides an automatic drying mechanism for negative pressure cups, comprising: a frame, on which a conveyor roller is mounted; a humidity detection device and an airtightness testing mechanism are mounted side-by-side at intervals along the Y direction on the frame behind the conveyor roller; a negative pressure clamp module is placed on the frame and located above the humidity detection device and the airtightness testing mechanism; multiple blower mechanisms are mounted above the negative pressure clamp module; and an air heating component is mounted on one side of the frame and connected to each blower mechanism via a pipe.
[0006] In the above technical solution, during actual operation, after the negative pressure fixture module completes the previous process, it is moved above the humidity detection device via a conveyor roller. Then, the air heating component heats the compressed air, and the air blower mechanism dries the inside of the negative pressure fixture module and its pipes. The humidity detection device detects the humidity of the gas in the negative pressure fixture module. When the humidity is within acceptable limits, it is determined that the negative pressure cups in the negative pressure fixture module have been dried. Then, a robotic arm moves the dried negative pressure fixture module above the airtightness testing mechanism, where an airtightness test is performed. This allows for the simultaneous drying of multiple negative pressure cups and subsequent airtightness testing, significantly improving the efficiency and quality of negative pressure cup drying.
[0007] Preferably, the negative pressure clamp module includes a clamp base, with multiple guide seats on both the left and right end plates of the clamp base. Two brackets are installed above the clamp base, arranged in parallel and spaced along the Y direction. Each bracket has a guide post at its bottom at both ends, which is inserted into the guide seat on the clamp base. Multiple upper clamps are installed on the inner top surface of each bracket along the X direction, and a lower clamp matching the upper clamps is installed on the inner bottom surface of each bracket. The negative pressure cup is clamped between the upper and lower clamps. A conduit is provided at the bottom of the lower clamp, and the top of the conduit communicates with the bottom opening of the negative pressure cup clamped between the upper and lower clamps. The bottom of the conduit is connected to the ultrasonic cleaning hole on the ultrasonic cleaning water tank. A spring is sleeved on the conduit, and the top of the spring abuts against the lower clamp. In actual operation, the negative pressure cup is placed between the upper and lower clamps on the negative pressure clamp module, and the cup is clamped between the upper and lower clamps by the spring pushing the upper clamp.
[0008] Preferably, the blower mechanism includes a mounting base, on which a Z-axis drive cylinder is mounted vertically downward along the Z-axis. A Z-axis movable seat is mounted at the bottom of the telescopic shaft of the Z-axis drive cylinder, and a nozzle is mounted on the Z-axis movable seat. A solenoid valve is mounted on the mounting base, and the air outlet of the solenoid valve is connected to the nozzle via a pipe. An air heating component is connected to the air inlet of the solenoid valve via a pipe. In actual operation, the Z-axis drive cylinder can drive the Z-axis movable seat to move the nozzle up and down. The hot air heated by the air heating component, controlled by the solenoid valve, is blown downward through the nozzle onto the negative pressure clamp module, achieving overall drying and heating of the negative pressure clamp module.
[0009] Preferably, a linear bearing is mounted on the mounting base, and a vertically upward-oriented guide post is mounted on the Z-axis movable base, the guide post being inserted into the linear bearing. This ensures that the Z-axis movable base can move stably up and down.
[0010] Preferably, the air heating assembly includes multiple air heaters mounted side-by-side at intervals on a frame, and the air heaters are connected to the blower mechanism via hot air transmission pipes. In actual operation, the compressed air is heated by the air heaters, then distributed to each blower mechanism via the hot air transmission pipes, and finally evenly discharged by the blower mechanism.
[0011] Preferably, the airtightness testing mechanism includes a Y-axis guide rail mounted on a frame, a Y-axis movable seat mounted on the Y-axis guide rail, a Y-axis drive cylinder mounted on one side of the Y-axis movable seat and connected to the Y-axis movable seat, two positioning rods arranged parallel and spaced apart along the X-direction mounted on the top of the Y-axis movable seat, an airtightness test strip mounted below the gap between the two positioning rods, and a vertically upward Z-axis test drive cylinder mounted below the airtightness test strip, with the telescopic shaft of the Z-axis test drive cylinder fixedly connected to the bottom of the airtightness test strip. In actual operation, the Y-axis drive cylinder can finely adjust the position of the airtightness test strip in the Y-direction. Once the airtightness test strip is accurately positioned, the Z-axis test drive cylinder drives the airtightness test strip upwards and presses it against the conduits of each negative pressure cup in the negative pressure fixture module. Then, air is blown into the negative pressure cups to test the airtightness of each negative pressure cup. After the test is completed, the Z-axis test drive cylinder drives the airtightness test strip to reset.
[0012] Preferably, a limiting cylinder is installed in the area between the conveying roller and the humidity detection device on the frame, and a limiting cylinder is also installed in the area between the humidity detection device and the airtightness testing mechanism. By setting the limiting cylinder, the position of the negative pressure clamp module can be kept stable during the drying process and the airtightness testing process.
[0013] The beneficial effects of the automatic drying mechanism for negative pressure cups provided by this utility model are as follows: This automatic drying mechanism for negative pressure cups has a high degree of automation and intelligence, enabling simultaneous drying of multiple negative pressure cups and subsequent airtightness testing, significantly improving the efficiency and quality of negative pressure cup drying. In actual operation, after the negative pressure clamp module completes the previous process, it is moved above the humidity detection device via a conveyor roller. Then, the air heating component heats the compressed air, which is then dried inside the negative pressure clamp module and its pipes via a blower mechanism. The humidity detection device detects the humidity of the gas in the negative pressure clamp module. When the humidity is within acceptable limits, it is determined that the negative pressure cups in the negative pressure clamp module have been dried. Then, a robotic arm moves the dried negative pressure clamp module above the airtightness testing mechanism for airtightness testing. This allows for the simultaneous drying of multiple negative pressure cups and subsequent airtightness testing, significantly improving the efficiency and quality of negative pressure cup drying.

In actual operation, after the negative pressure clamp module 2 completes the previous cleaning process, it is moved above the humidity detection device 5 by the conveyor roller 7. Then, the air heating component 4 heats the compressed air and dries the inside and pipes of the negative pressure clamp module 2 by the blower mechanism 3. The humidity detection device 5 detects the humidity of the gas in the negative pressure clamp module 2. When the humidity is within the acceptable range, it is determined that the negative pressure cup 23 in the negative pressure clamp module 2 has been dried. Then, the robot moves the dried negative pressure clamp module 2 above the air tightness testing mechanism 6. The air tightness testing mechanism 6 performs an air tightness test on the negative pressure clamp module 2, thereby realizing the simultaneous drying of multiple negative pressure cups 23 and the air tightness test after drying, which greatly improves the efficiency and quality of drying the negative pressure cups 23.
[0025] Reference Figure 3 and Figure 4 As shown, the negative pressure clamp module 2 includes a clamp base 29. Two guide seats 210 are provided on both the left and right end plates of the clamp base 29. Two brackets 21, arranged parallel and spaced along the X-direction, are installed above the clamp base 29.

Multiple upper clamps 24, arranged parallel and spaced along the Y-direction, are installed on the inner top surface of each bracket 21. The inner bottom surface of each bracket 21... Each clamp 24 is equipped with a lower clamp 25 that matches the upper clamp 24. The negative pressure cup 23 is clamped between the upper clamp 24 and the lower clamp 25. A conduit 26 is provided at the bottom of the lower clamp 25, penetrating through the lower clamp 25. The top of the conduit 26 communicates with the bottom opening of the negative pressure cup 23 clamped between the upper clamp 24 and the lower clamp 25. The bottom of the conduit 26 is connected to the ultrasonic cleaning hole 81 provided on the ultrasonic cleaning water tank 8. A spring 27 is sleeved on the conduit 26, and the top of the spring 27 abuts against the lower clamp 25.

In actual operation, the Z-axis drive cylinder 33 can drive the Z-axis moving seat 34 to move the nozzle 35 up and down. The hot air heated by the air heating component 4, after being controlled by the solenoid valve 32, is blown downward through the nozzle 35 to the negative pressure clamp module 2, thereby achieving overall drying and heating of the negative pressure clamp module 2. A linear bearing 37 is also installed on the mounting base 31, and a vertically upward guide post 36 is installed on the Z-axis moving base 34. The guide post 36 is inserted into the linear bearing 37 to ensure that the Z-axis moving base 34 can move up and down stably.

The air heaters 41 are connected to the blower assembly 3 via hot air transmission pipes 42.

When the position of the airtightness test strip 65 is accurate, the Z-axis test drive cylinder 66 drives the airtightness test strip 65 to the top and press it against the conduit 26 of each negative pressure cup 23 in the negative pressure fixture module 2. Then, air is blown into the negative pressure cup 23 to test the airtightness of each negative pressure cup 23. After the test is completed, the Z-axis test drive cylinder 66 drives the airtightness test strip 65 to reset.
