Existing airtightness testing machines for blood glucose meters are separate from the production line, typically requiring manual placement of the meter onto a fixture before testing. This process is inefficient, requiring manual loading and unloading and resulting in low automation. Furthermore, being independent of existing blood glucose meter assembly lines, it is incompatible with them and cannot automate the entire assembly and airtightness testing process.

[0007] Furthermore, both the first and second robotic arm material handling devices include a robotic arm and several material handling mechanisms installed at the end of the robotic arm. Each material handling mechanism includes a material handling suction cup and a material handling lifting drive cylinder. The material handling suction cup is installed at the power output end of the material handling lifting drive cylinder.

[0008] Furthermore, the transplanting device includes a linear module and a carrier, the carrier being mounted on the linear module and capable of translating along the linear module.

[0009] Furthermore, the airtight fixture has an annular groove, and a sealing ring is installed inside the annular groove.

[0010] Furthermore, the clamping mechanism includes a clamping lifting drive cylinder and a pressure block, with the pressure block installed at the power output end of the clamping lifting drive cylinder.

[0028] Example: A blood glucose meter airtightness tester, such as Figures 1 to 5 As shown, the system includes a machine base 1 and a first robotic arm picking device 2, a transfer device 3, a second robotic arm picking device 4, an airtightness testing fixture area 5, and an airtightness tester 6, all located on the machine base. The first robotic arm picking device and the second robotic arm picking device are located at opposite ends of the transfer device. The first robotic arm picking device places the product to the right end of the transfer device, and the second robotic arm picking device picks up the product from the left end of the transfer device and places it in the airtightness testing fixture area.

[0029] The airtightness testing fixture area is equipped with multiple sets of airtightness testing mechanisms. Each set of airtightness testing mechanisms includes a pressure bracket 51, a base 52, an airtightness fixture 53 for placing the product mounted on the base, a translation drive cylinder 54, and a clamping mechanism 55 mounted on the pressure bracket. The base is mounted on the machine platform, the airtightness fixture is mounted on the base, and one end of the push rod of the translation drive cylinder is fixed to the fixture. The clamping mechanism is mounted on the pressure bracket and can press down to clamp the product onto the airtightness fixture.

[0030] The airtight fixture is connected to the airtightness tester via a pipeline.

[0031] In this embodiment, both the first robotic arm material handling device 2 and the second robotic arm material handling device 4 include a robotic arm 21 and a plurality of material handling mechanisms installed at the end of the robotic arm. Each material handling mechanism includes a material handling suction cup 22 and a material handling lifting drive cylinder 23. The material handling suction cup is installed at the power output end of the material handling lifting drive cylinder.

[0032] In this embodiment, the transplanting device 3 includes a linear module 31 and a carrier 32. The carrier is mounted on the linear module and can be translated along the linear module.

[0033] In this embodiment, the airtight fixture is provided with an annular groove, and a sealing ring 531 is installed in the annular groove.

[0034] In this embodiment, the pressing mechanism 55 includes a pressing lifting drive cylinder 551 and a pressing block 552, with the pressing block installed at the power output end of the pressing lifting drive cylinder.

[0035] In this embodiment, the airtight fixture and the base are slidably connected by a linear guide rail 57.

[0036] In this embodiment, the upper surface of the airtight fixture is provided with two conical guide posts 532, and the surface of the pressure block is provided with corresponding guide holes.

[0037] In this embodiment, the airtight fixture is connected to the solenoid valve 56 via a pipeline, and the solenoid valve is connected to the airtightness tester via a pipeline.

[0038] The first and second robotic arm material handling devices use robotic arms to drive material handling suction cups to pick up materials. The robotic arms can be four-axis robotic arms to realize the picking, placing and transporting of products with fast, sensitive and high precision. The material handling lifting drive cylinder is used to lift the material handling suction cups.

[0039] Transplanting device: In this embodiment, it mainly consists of two linear modules and a carrier; the first robotic arm picks up the product and places it on the carrier, and the linear modules move the carrier from the right end to the left end (according to...). Figure 1 From this perspective, it improves the speed of product handling and enables intelligent positioning.

[0040] Air tightness tester: This is an air tightness testing device that uses a differential pressure sensor as its core to determine the air tightness, sealing performance, and waterproof performance of a product by detecting the pressure difference between the tested component and a standard component. This air tightness tester is an existing instrument and will not be described in detail.

[0041] Airtight Fixture: The second robotic arm places the product onto the airtight fixture. A translational drive cylinder moves the product directly beneath the clamping mechanism, and a clamping drive cylinder drives the pressure plate downwards, clamping the product. The sealing ring deforms to form a seal, and the airtightness tester begins operation, filling the product with compressed air (or nitrogen) to the set pressure (e.g., 50 kPa). During the pressure holding phase (5-10 seconds), a pressure sensor monitors the pressure decay. Leakage detection: If the pressure drop exceeds a threshold (e.g., 0.5 kPa / s), an NG signal is triggered. The solenoid valve switches to exhaust, the clamping drive cylinder retracts, and the translational drive cylinder drives the airtight fixture to move out, allowing the second robotic arm to remove the workpiece. Its core function is to efficiently and accurately complete the sealing test. The airtight fixture has gas inlets and outlets, which are connected to a solenoid valve via pipelines. The solenoid valve is then connected to the airtightness tester via pipelines. Controlling the solenoid valve allows for switching between air intake and exhaust.

[0042] The working principle and process of this utility model:

[0043] The first robotic arm picking device grabs the product and places it on the carrier. The linear module moves the carrier from the right end to the left end. The first robotic arm picking device places the product in the pneumatic fixture. The translation drive cylinder moves the product to directly below the pressing mechanism. The pressing drive cylinder drives the pressure plate downward to press the product. The airtightness tester starts testing and finally gives the test data, realizing the automation of the whole process.
