Description

Technical Field

[0001] This utility model relates to the field of power cap testing technology, and in particular to a power cap helium detector. Background Technology

[0002] In the manufacturing process of power caps, their sealing performance is a crucial quality indicator. As a key component, the power cap is used to seal the cavities of various power equipment, preventing internal gas or liquid leakage and ensuring the safe and stable operation of the equipment. Poor sealing performance of the power cap may lead to leakage of the internal medium, resulting in equipment failure, performance degradation, or even safety accidents.

[0003] Currently, traditional testing methods and equipment for the airtightness inspection of power caps have many shortcomings. Some methods use simple pressure testing, which has low accuracy and cannot accurately detect minute leaks, making it unsuitable for power caps with extremely high airtightness requirements. Other testing equipment has low automation, relying heavily on manual operation, resulting in low efficiency and inconsistent results due to variations in human operation. Furthermore, existing testing equipment is not well-designed in terms of testing processes and functions, failing to effectively process defective products. For example, it cannot accurately re-inspect defective products or efficiently discharge good and defective products, which negatively impacts production efficiency and product quality control.

[0037] Please see Figures 1 to 13 The present invention provides a power cap helium detector, comprising a feeding synchronous belt robot 10, a cap alignment component 20 disposed on one side of the feeding synchronous belt robot 10, a helium detection main robot 30 disposed on one side of the cap alignment component 20, a helium detection station mold turntable 40 disposed on one side of the helium detection main robot 30, a helium detection upper press 50 disposed on the upper side of the helium detection station mold turntable 40, a helium detection discharge main robot 60 disposed on one side of the helium detection station mold turntable 40, and a good product discharge line 70 and a defective product discharge line 80 disposed on one side of the helium detection discharge main robot 60.

[0038] The aforementioned power cap helium detector, through the setting of a good product discharge line 70 and a defective product discharge line 80, achieves efficient separation of good and defective products, thereby improving production efficiency.

[0039] In one embodiment of this utility model, it further includes a re-inspection feeding robot 90 disposed on one side of the defective product discharge line 80, a re-inspection good product discharge robot 100 disposed on one side of the re-inspection feeding robot 90, a re-inspection discharge robot 110, a re-inspection station mold turntable 120 disposed below the re-inspection discharge robot 110, a puncture component 130 disposed above the re-inspection station mold turntable 120, and a re-inspection station helium inspection mechanism 140 disposed on one side of the puncture component 130. Specifically, in this embodiment of the utility model, the re-inspection good product discharge robot 100, the re-inspection discharge robot 110, and the re-inspection discharge robot 110 are all driven by servo motors, and the cover plate is adsorbed by a vacuum cylinder adsorption robot, and then the cover plate is transferred by a servo motor. The structure and working principle of the re-inspection station mold turntable 120 are similar to those of the helium inspection station mold turntable 40. It is also driven by a motor to rotate, sequentially transporting the power caps placed on it to different stations for re-inspection operations. It should be noted that the puncture assembly 130 is installed above the re-inspection station mold turntable 120. When the power cap rotates to a position below the puncture assembly 130, the puncture assembly activates, puncturing a specific area on the power cap to more accurately test its sealing performance under actual use during re-inspection. Specifically, the puncture assembly 130 includes at least a puncture needle, a servo motor that moves the puncture needle, and a lifting motor that moves the puncture needle up and down to achieve the puncture function.

[0040] In one embodiment of the present invention, the re-inspection feeding robot 90 includes a re-inspection servo motor 91 and a re-inspection robot 92 connected to the re-inspection servo motor 91.

[0041] In one embodiment of this utility model, the feeding synchronous belt robot 10 includes a feeding servo motor 11 and multiple vacuum adsorption cylinders 12 disposed at the moving end of the feeding servo motor 11. Specifically, the feeding belt transports the cover plate from the previous station to the designated position. When the position sensor on the production line detects that the cover plate has arrived, the three vacuum adsorption cylinders 12 on the robot sequentially pick up the cover plate at the designated position. Then, the feeding servo motor 11 moves towards the cover plate alignment component 20. Upon reaching the designated position, the vacuum adsorption cylinders 12 simultaneously place the three picked-up cover plates onto the cover plate alignment component 20, thus realizing the automatic feeding function.

[0042] In one embodiment of this utility model, the cover plate straightening assembly 20 includes an upper lifting cylinder 21 and four positioning blocks 22 disposed around the upper lifting cylinder 21. The upper lifting cylinder 21, in conjunction with the structural components, performs four-way positioning of the cover plate; specifically, the upper lifting cylinder 21 at the bottom of the cover plate straightening assembly 20 pushes upward, and the positioning blocks 22 located on the four sides at the top open outward; after the feeding synchronous belt robot arm 10 transports the cover plate onto the cover plate straightening assembly 20, the upper lifting cylinder 21 descends, and the positioning blocks 22 located on the four sides at the top move towards the center, thus straightening the cover plate.

[0043] In one embodiment of this utility model, a single-station helium inspection mechanism 140 is also included to perform helium inspection on a single product.

[0044] In one embodiment of this utility model, the helium detection main robot 30 includes a helium detection servo motor 31 and a helium detection robot 32 connected to the helium detection servo motor 31. The helium detection servo motor 31 drives the helium detection robot 32 to move left and right, and the cover plate is transported by the adsorption cylinder on the helium detection robot 32. After the cover plate straightening component 20 completes the straightening of the cover plate, the helium detection main robot 30 moves to the designated position for picking up the cover plate, picks up the cover plate from the cover plate straightening component 20, and then transports it to the helium detection station mold turntable 40, and then places the cover plate on the helium detection station mold turntable 40.

[0045] In one embodiment of this utility model, the helium detection station turntable 40 includes multiple waiting station molds 41 and multiple helium detection station molds 42. Each waiting station mold 41 and each helium detection station mold 42 has air holes corresponding to the positions of the pole and the explosion-proof sheet, and the air holes are connected to the helium detector. Specifically, the helium detection station turntable 40 is an 18-station turntable, divided into 9 waiting station molds 41 and 9 helium detection station molds 42. The airtightness of the cover plates at each of the 9 stations is tested. The helium detection main robot 30 transports the cover plates that have been aligned to the correct position to the waiting station. After loading 9 cover plates, the turntable transfers the waiting station molds 41 to the helium detection station and simultaneously transfers the 9 cover plates that have completed the helium detection to the waiting station.

[0046] In one embodiment of this utility model, the helium detection press 50 includes a press cylinder 51 and a press mold 52 disposed on the upper end of the press cylinder 51, wherein a sealing ring is provided inside the press mold. Specifically, the press cylinder 51 aligns the sealing ring on the surface of the press mold 52 with the positive and negative terminals, explosion-proof sheet, etc. above the cover plate to form a sealed cavity. Then, the air passage connected to the press mold 52 performs vacuum extraction to remove air from the sealed cavity of the cover plate, and then injects helium into the position. Below the helium detection station mold turntable 40, a helium detector connected to the air hole evacuates air from the helium detection station mold 42 into the helium detector. The helium detector analyzes the extracted air to detect whether the air contains helium.

[0047] In one embodiment of this utility model, the helium detection and unloading main robot 60 includes an unloading servo motor 61 and an unloading robot 62 mounted on the unloading servo motor 61. After the helium detection is completed, the unloading robot 62 moves to the disc waiting station, the cylinder descends, and simultaneously picks up the nine cover plates on the waiting station. The unloading servo motor 61 drives the robot to move towards the unloading production line position, placing the cover plates that have passed the helium detection on the good product production line 70 and the unqualified cover plates on the defective product production line 80.

[0048] In practical implementation, the defective product production line 80 can use a stepper motor to transport the helium-tested non-conforming cover plates to the re-inspection station. The helium-testing main robot 60 places the non-conforming cover plates on the defective product discharge production line 80, and the conveyor belt transports the non-conforming cover plates to the re-inspection station. A positioning sensor at the end of the production line detects the cover plates, and the cover plate straightening mechanism at the re-inspection station straightens and positions them. It should be noted that the cover plate straightening mechanism here has the same structure and function as the cover plate straightening component 20. Specifically, the good product production line 70 has the same structure and working principle as the defective product production line 80.

[0049] The aforementioned powered cap helium detector has at least the following beneficial effects:

[0050] High-precision testing: By connecting the gas holes on the helium testing station turntable 40 corresponding to the pole and explosion-proof diaphragm positions to the helium detector, the sealing performance of the power cap at key parts can be accurately tested. Compared with traditional testing methods, the testing accuracy is greatly improved, and tiny leak points can be accurately detected, meeting the testing requirements for high sealing performance of power caps.

[0051] High degree of automation: The feeding synchronous belt robot 10, the helium detection main robot 30, the helium detection discharging main robot 60, and the re-inspection feeding robot 90 are all driven by servo motors. With the help of the automatic control system, the fully automated process of power cap from feeding to detection to discharging can be realized, which reduces manual operation, reduces labor intensity, and improves detection efficiency and consistency of detection results.

[0052] A comprehensive defective product handling process is in place: A dedicated re-inspection feeding robot (90), a re-inspection station turntable (120), a puncture component (130), and a single-station re-inspection helium detection mechanism (140) are installed, enabling precise re-inspection of detected defective products and further improving product quality control.
