A push-type automatic plastic gun tip loader

Abstract

A push-type automatic plastic gun head loader comprises a feeding mechanism shell, side supports, supporting springs, shaking motors, a feeding motor, a conveyor belt, a guiding plate, a base, a guide rail base, pushing-off vehicles, a clamping mechanism, L-shaped pushing plates, infrared height sensors and releasing mechanisms, wherein the supporting springs are arranged at the upper ends of the shaking motors; the side supports are arranged at the upper ends of the supporting spring; sides of the feeding mechanism shell are connected with the side supports; a row of feeding rolls is arranged inside the feeding mechanism shell; a rotating shaft at the outer part on the side surface of the feeding mechanism shell is sleeved with the conveyor belt; the guiding plate is arranged at an opening end of the feeding mechanism shell; the clamping mechanism is arranged below the end part of the guiding plate; the bottom of the clamping mechanism is fixed in the middle of the guide rail base; one pushing-off vehicle is arranged on each of two guide rails of the guide rail base; one L-shaped pushing plate is arranged on each pushing-off vehicle; the releasing mechanisms are arranged on the two sides of the guide rail base; and a gun box into which gun heads are to be inserted is arranged below the releasing mechanisms. By adopting the structure, the push-type automatic plastic gun head loader can quickly and efficiently load plastic gun heads for biochemical and biological laboratories.

Description

technical field [0001] The invention relates to the field of biological and biochemical experimental equipment, in particular to a push-type automatic plastic tip loader. Background technique [0002] Assembling plastic tips is one of the routine tasks in biochemical and biological laboratories. The general operation method is to manually put the plastic tips into the tip box one by one for subsequent sterilization or direct use. The daily consumption of pipette tips in the biological laboratory ranges from more than 10 boxes to as many as hundreds of boxes, all of which require special personnel or take turns to manually assemble the pipette tips. It takes about 4-5 minutes to fill a box of tips. Therefore, it takes hours to manually load the tips that are used every day, which is time-consuming and labor-intensive. However, the introduction of imported automatic tip loaders is expensive, and it is difficult to configure them as routine equipment in biological laboratories...

AI Technical Summary

Problems solved by technology

[0003] At present, the pneumatic push technology is relatively mature. Pneumatic push has the characteristics of fast push speed, but if it is applied to gun head loading, there are the following problems. It is necessary to ensure that they are separated horizontally one by one before loading; 2) Since the gun heads after coming out are one big and the other small, how to distinguish and place them is also an urgent need to solve; 3) Because the pneumatic push speed is often faster, so How to achieve precise push also needs to be solved urgently; 4) In addition, it is necessary to ensure that the tip of the gun falls to the corresponding position with the small end facing down during the push process
