Description

Technical Field

[0001] This utility model belongs to the field of battery cover testing technology, and more specifically, it relates to a helium testing device for new energy battery covers. Background Technology

[0002] Currently, helium testing involves evacuating the product under inspection and then filling it with helium gas at a certain pressure. The product is surrounded by a vacuum space with a specific vacuum level requirement, which is connected to the leak port of the helium detector. If the workpiece has a leak, the helium gas that has leaked into the vacuum space can be detected by the helium detector.

[0003] Chinese patent CN113720543A discloses an automated helium testing device for battery covers, including a feeding unit, a discharging unit, and a helium testing unit. The feeding unit includes a feeding conveying mechanism, a feeding rotation mechanism, and a material transfer mechanism. The discharging unit includes a discharge conveying mechanism and an NG (Not From Good) discharge conveying mechanism. The helium testing unit includes a material turnover mechanism and several helium testing stations. Each helium testing station includes a helium testing top chamber and a helium testing base. The helium testing top chamber has a top-pressure sealed chamber and a helium gas source. The helium testing base includes a supporting sealed chamber, a helium gas spectrometer detector, and a vacuum detector. This invention meets the requirements for battery cover airtightness testing, has a high degree of automation, is easy to integrate into fully automated production lines, operates efficiently and smoothly, and provides reliable and stable gas testing. The combination of vacuum testing and helium testing meets the requirements for initial screening and rejection, reduces helium testing costs, and decreases the reset stroke, improving testing efficiency. It also features feeding steering and discharging flipping functions to meet the requirements for smooth operation of automated production lines.

[0004] While this equipment can handle the loading and unloading of battery covers and perform helium testing, it lacks the ability to autonomously distinguish between different battery covers. The material transfer process during helium testing is complex, making it difficult to quickly differentiate between defective and qualified products. The helium testing process is lengthy, and after testing, the covers are simply conveyed out; manual collection is still required. If the front and back of the covers are mixed up during loading, the equipment cannot autonomously flip them for collection, necessitating manual shutdown and flipping. This is extremely troublesome, significantly reducing the overall progress of the helium testing process and impacting subsequent material collection and packaging. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a helium detection device for new energy battery covers, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a helium detection device for new energy battery cover plates, comprising a workbench, a support frame on the workbench, a first linear module on the top of the support frame, a second linear module connected to the movable end of the first linear module, the second linear module forming a 90-degree angle with the first linear module, a movable seat connected to the movable end of the bottom of the second linear module, symmetrical lifting cylinders on both sides of the movable seat, a third suction cup on the extension end of the lifting cylinder for material collection, a material collection component inside the workbench, a robotic arm on the workbench, a first suction cup on the movable port of the robotic arm, a feeding mechanism on the workbench for conveying cover plate components, multiple bases on both sides of the robotic arm, and helium detection mechanisms on the multiple bases.

[0007] As an optional solution of this utility model, the receiving component includes a hoisting frame, a lifting cylinder is provided at the bottom of the hoisting frame, a lifting frame is provided at the extension end of the lifting cylinder, the lifting frame slides inside the hoisting frame, and a defective product tray and a qualified product tray are respectively placed on the top of the lifting frame.

[0008] As an optional solution of this utility model, the feeding mechanism includes a conveyor table, an adjustment frame is provided on the conveyor table, and symmetrical guide plates are provided on the adjustment frame to limit and guide the cover plate.

[0009] As an optional solution of this utility model, the helium detection mechanism includes a guide rod, which is fixed at the four corners of the base. A top plate is provided on the top of the guide rod, and an electric cylinder is installed on the top plate. The extension end of the electric cylinder is connected to a sealing seat, and a pressure plate is provided at the bottom of the sealing seat. The pressure plate is slidably fitted on the guide rod. A helium detector is provided on the sealing seat, and the bottom of the helium detector is connected to the pressure plate. A detection seat is provided below the pressure plate, and symmetrical sliders are installed at the bottom of the detection seat. A slide rail is slidably fitted on the sliders and is fixed to the base. An electric telescopic rod is provided below the detection seat, and the extension end of the electric telescopic rod is connected to the detection seat. A detection groove is provided inside the detection seat, and an air inlet valve is provided on one side of the detection seat, which is connected to the detection groove.

[0010] As an optional solution of this utility model, an alarm is provided on the top plate, and the alarm is electrically connected to a helium detector.

[0011] As an optional solution of this utility model, a positioning seat is provided on the workbench, a rotary cylinder is provided on one side of the positioning seat, a second suction cup is provided on the rotating end of the rotary cylinder, a placement seat is provided on one side of the second suction cup, and a camera is provided on the robotic arm. The robotic arm positions the cover plate on the placement seat.

[0012] This utility model provides a helium detection device for new energy battery cover plates, which has the following beneficial effects:

[0013] The robotic arm uses its first suction cup to pick up each cover piece individually and place them into the mounting slot of the detection seat. The detection seat is then moved to directly beneath the pressure plate using an electric telescopic rod. An electric cylinder presses down the pressure plate to seal it, ensuring the helium gas detection is airtight. Internal air is evacuated through the intake valve, and helium is then introduced through the intake valve. The helium gas is then tested using a helium detector. If the alarm does not sound, the airtightness is good; if the alarm sounds, it indicates a helium leak and poor airtightness of the cover piece. The robotic arm immediately removes the cover piece and transfers it to the placement seat, where a third suction cup places it in place. If the product is acceptable, the third suction cup will place the cover plate in the acceptable product tray, thus automatically distinguishing the quality of the cover plate parts. This eliminates the need for continuous manual sorting and collection. The camera on the robotic arm can distinguish the front and back of the cover plate parts. If it is necessary to change the front and back of the cover plate parts, the second suction cup will be rotated by a rotary cylinder to change the front and back of the cover plate parts. Then, the third suction cup will pick up the cover plate parts on the second suction cup and put them into the designated area, realizing automatic flipping of the cover plate parts. This greatly improves the continuity of the entire helium detection process and avoids slow material collection caused by downtime. Attached Figure Description

[0024] Please see Figures 1 to 6This utility model provides a technical solution: a helium detection device for new energy battery covers, including a workbench 1, a support frame 2 on the workbench 1, a first linear module 3 on the top of the support frame 2, a second linear module 4 connected to the movable end of the first linear module 3, the second linear module 4 forming a 90-degree angle with the first linear module 3, a movable seat 401 connected to the movable end of the bottom of the second linear module 4, symmetrical lifting cylinders 402 on both sides of the movable seat 401, a third suction cup 403 on the extension end of the lifting cylinder 402 for material collection, and a material collection component inside the workbench 1, including a lifting frame 192, with a lifting mechanism at the bottom of the lifting frame 192. The cylinder 191 has a lifting frame 19 at its extension end. The lifting frame 19 slides within the hoisting frame 192, and the top of the lifting frame 19 holds a defective product tray 5 and a qualified product tray 6. A robot arm 16 is mounted on the worktable 1, and a first suction cup 161 is mounted on the moving port of the robot arm 16. A feeding mechanism is mounted on the worktable 1, and a cover plate 15 is conveyed on the feeding mechanism. The feeding mechanism includes a conveyor 14, an adjusting frame 141 is mounted on the conveyor 14, and symmetrical guide plates 142 are mounted on the adjusting frame 141. The guide plates 142 can limit and guide the cover plate 15. Multiple bases 7 are mounted on both sides of the robot arm 16, and helium detection mechanisms are mounted on the multiple bases 7.

[0025] The helium detection mechanism includes guide rods 701, which are fixed at the four corners of a base 7. A top plate 9 is mounted on the top of the guide rods 701, and an electric cylinder 10 is installed on the top plate 9. The extension end of the electric cylinder 10 is connected to a sealing seat 11. A pressure plate 8 is mounted at the bottom of the sealing seat 11, and the pressure plate 8 is slidably fitted onto the guide rods 701. A helium detector 12 is mounted on the sealing seat 11, and its bottom is connected to the pressure plate 8. A detection seat 704 is located below the pressure plate 8, and symmetrical sliders are mounted at the bottom of the detection seat 704. A slide rail 702 is slidably fitted onto the sliders and fixed to the base 7. An electric telescopic rod 703 is located below the detection seat 704. The electric telescopic rod 703 is connected to the detection seat 704 at its extension end, which can move the detection seat 704 for loading and inspection. The detection seat 704 is equipped with a detection groove, and an air inlet valve 705 is provided on one side of the detection seat 704. The air inlet valve 705 is connected to the detection groove, so that helium can be introduced into the detection groove. The helium detector 12 can detect the helium. If no helium is detected, it means that the cover plate 15 is sealed. An alarm 13 is provided on the top plate 9. The alarm 13 is electrically connected to the helium detector 12. When the helium value exceeds the standard, the alarm 13 will start to sound. The robot arm 16 will prioritize taking out the defective products and placing them in the defective product tray 5.

[0026] A positioning seat 17 is provided on the workbench 1. A rotary cylinder 171 is provided on one side of the positioning seat 17. A second suction cup 172 is provided on the rotating end of the rotary cylinder 171. A placement seat 18 is provided on one side of the second suction cup 172. A camera is provided on the robot arm 16. Since the front and back of the cover plate 15 are confused after inspection, the camera on the robot arm 16 is used to distinguish them. The cover plate 15 is then positioned on the placement seat 18. After confirming that the positions are reversed, the second suction cup 172 is rotated by the rotary cylinder 171 to attract the cover plate 15, thereby changing the front and back of the cover plate 15. Then, a third suction cup 403 is used for sorting and collecting.

[0027] The specific usage and function of this embodiment are as follows: Personnel first place the cover plate 15 on the conveyor table 14 and slowly transport it to the loading area. The first suction cup 161 on the robotic arm 16 picks up the cover plate 15 one by one and places them sequentially into the mounting slot of the detection seat 704. The electric telescopic rod 703 is activated to move the detection seat 704 directly below the pressure plate 8. The electric cylinder 10 presses down the pressure plate 8 to seal it. After completion, the internal air is extracted through the air inlet valve 705, and then helium is input through the air inlet valve 705. The helium is then detected by the helium detector 12. If the alarm 13 does not sound, the system will detect the helium. If the airtightness is good, it indicates that the airtightness is good. If the alarm 13 sounds, it means that there is a helium leak and the airtightness of the cover plate 15 is poor. The robot arm 16 will immediately remove it and transfer it to the placement seat 18. The third suction cup 403 will place the cover plate 15 in the defective product tray 5. If it is qualified, the third suction cup 403 will place the cover plate in the qualified product tray 6. If it is necessary to change the side of the cover plate 15, the second suction cup 172 will be rotated by the rotary cylinder 171 to change the front and back of the cover plate 15. Then the third suction cup 403 will adsorb the cover plate 15 on the second suction cup 172 to the designated area. It is flexible and versatile.
