Description

Technical Field

[0001] The present application relates to the field of injection pens, and more particularly to a disposable injection pen testing machine. Background Art

[0002] An injection pen is a type of syringe. It is named so because its shape is similar to a fountain pen. It is a pen-shaped syringe pre-filled with medicine. Common injection pens include insulin injection pens and adrenaline injection pens, etc. Usually, the user operates the injection pen by himself. In the case where the user lacks professional skills and knowledge, various performances of the injection pen (such as: striking force, injection time, dosage accuracy, and needle insertion depth, etc.) need to be accurately controlled. Therefore, after the injection pen is produced, it is very important to take samples of the injection pen for testing.

[0003] There are many items that need to be detected for injection pens. However, in the traditional injection pen testing device technology, the testing items detected by the testing device are single. One testing device can only detect one item. Different testing items require different testing devices to be prepared. The integration degree and automation degree of the testing device are relatively low, which is not convenient for testing injection pens and will make the testing of injection pens time-consuming and laborious. Summary of the Invention

[0041] Specifically, the working principle of the disposable injection pen detector: During use, the carrying fixture 220 is pulled out through the handle 221. Then, several injection pens 600 can be inserted into the several carrying slots 222. Then, the carrying fixture 220 is pushed into the frame 100. Then, the first XZ linear module 120 drives the first pneumatic finger 130 to move downward, thereby driving the first pneumatic finger 130 to move towards the injection pen 600, so that the first pneumatic finger 130 can clamp the injection pen 600. Then, the first XZ linear module 120 drives the first pneumatic finger 130 and the injection pen 600 to move, thereby driving the injection pen 600 to move towards the second pneumatic finger 310. Then, the first XZ linear module 120 drives the injection pen 600 to move downward, so that the injection pen 600 can enter the second pneumatic finger 310. The second pneumatic finger 310 and the cap pulling force sensor 311 clamp the cap of the injection pen 600. Then, the first XZ linear module 120 drives the injection pen 600 to move upward, so that the injection pen 600 can be separated from the cap. Thus, the pulling force for removing the cap of the injection pen 600 can be obtained through the cap pulling force sensor 311. The second pneumatic finger 310 releases the cap of the injection pen 600, and the cap will fall into the collection box 140 through the collection conduit 320. The first XZ linear module 120 drives the injection pen 600 to move towards the measuring cup 420. Then, the first XZ linear module 120 drives the injection pen 600 to move downward, so that the injection pen 600 can contact the support block 433, thereby causing the injection pen 600 to squeeze the support block 433. The support force detection sensor 432 can detect the pressure of the injection pen 600. The drug inside the injection pen 600 will be sprayed into the measuring cup 420. Thus, the milliliters and weight of the drug can be detected through the measuring cup 420 and the electronic balance 410. During the downward movement of the injection pen 600, the needle insertion depth displacement sensor 500 can detect the moving distance of the injection pen 600. The second XZ linear module 710 can drive the height measuring sensor 700 to move up and down, thereby measuring the height of the needle of the injection pen 600. Thus, multiple items of the injection pen 600 can be detected at one time, with a high degree of integration and automation, which is convenient for detecting the injection pen 600 and makes the multi-item detection of the injection pen 600 more time-saving and labor-saving.
