[0002] A pipette, also known as a pipette gun, is a measuring tool for transferring liquid from an original container to another container within a certain measuring range. It is widely used in biology, chemistry and other fields. Conventional pneumatic pipettes usually consist of a pipette body and a TIP head (also known as a suction tip), wherein the pipette body is provided with a gun head for use with the TIP head. When existing equipment produces and processes TIP heads, since TIP heads are disposable consumables, the demand for TIP heads is gradually increasing, and thus the requirements for TIP head production are also gradually increasing. However, during the demolding process of the TIP heads of existing equipment, due to accidents with individual TIP heads during the demolding process, the TIP heads may stick to the gun head, affecting the next use. Therefore, a device is needed to detect whether the TIP head has been successfully removed when it falls off the gun head. Utility Model Content

DETAILED DESCRIPTION

[0015] The accompanying drawings are for illustrative purposes only and are not to be construed as limitations on this patent. To better illustrate this embodiment, some components of the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted from the accompanying drawings.

[0016] Referring to the accompanying drawings, a device for detecting whether a TIP head has been successfully removed includes a pipette body 1, a tip detachment button 2, an elastic nozzle 3 and a TIP head 4. A clamping and fixing structure 5 is clamped on the lower half of the pipette body 1. The clamping and fixing structure 5 includes a clamping clamp 6. A rubber pad 7 is provided on the clamping surface of the clamping clamp 6. The clamping clamp 6 is connected to a clamping rod 8. The clamping rod 8 is connected to a spring 9 and a sleeve 10. A rotating shaft 11 passes through the middle of the sleeve 10. The rotating shaft 11 is connected to a connecting rod 12. The connecting rod 12 is connected to a detection box 13. A fixed shaft 1 is provided in the detection box 13. 4 and a bearing base 16, a rotating wheel 15 is sleeved on the fixed shaft 14, the bearing base 16 is connected to the bearing 17, the bearing 17 is connected to the rotating rod 18, a gear 19 is sleeved on the rotating rod 18, the gear 19 is meshed with the rack 21 in the slide 20, the rack 21 is fixedly connected to the detection support rod 22, the bottom of one end of the detection support rod 22 is connected to the support rod 23, the support rod 23 is connected to the shaft 24, a roller 25 is sleeved on the shaft 24, and a camera shield 26 is provided at the bottom of the other end of the detection support rod 22, and a high-definition camera 27 is installed in the camera shield 26.
