Automatic loading device for serological pipette air tightness detection

Abstract

The invention relates to the technical field of biomedical instruments, and particularly discloses an automatic loading device for serological pipette air tightness detection. The device comprises side boards, a first vertical baffle, second vertical baffles, feeding slides, a third vertical baffle, a fourth vertical baffle, a discharging slide, a baseboard, a cube poking block and a first throughhole, wherein second through holes are formed in the cube poking block, adjustment parts and slides are arranged in the second through holes, each adjustment part comprises a handle part and two adjustment rods, sawtooth parts are arranged on the adjustment rods, sawteeth on the sawtooth parts are of stepwise rising structures, third through holes are formed in the cube poking block, adjustment blocks are arranged in the third through holes, one end of each adjustment block is of a conical structure matched with the corresponding sawteeth on the corresponding sawtooth parts, adjustment grooves are formed in both side surfaces of the interior of each third through hole, and second adjustment springs are arranged in the adjustment grooves. The automatic loading device for serological pipette air tightness detection has the characters that loading is tidy, a to-be-detected pipette does not drop, a material opening is not blocked, and the adjustment performance and the adaptability are good.

Description

technical field [0001] The invention relates to the technical field of biomedical devices, in particular to an automatic feeding device for air tightness detection of serological pipettes. Background technique [0002] After the pipette head or nozzle is welded, the airtightness test is usually required. At present, most of the pipette airtightness testing equipment lacks automatic feeding devices, which are manually loaded one by one, which also makes manual The labor intensity is high, and it cannot meet the requirements of batch testing in production. Even if there is a feeding device, it is simple to put all the pipettes to be tested into the hopper of the feeding device. The pipettes in the hopper are placed in a mess. It cannot meet the subsequent detection requirements, and the pipettes in the hopper are easy to fall from the outlet and cannot fall to the detection equipment. The outlet of the hopper is blocked; because the serological pipettes have different specifi...

[0002] After the pipette head or nozzle is welded, the airtightness test is usually required. At present, most of the pipette airtightness testing equipment lacks automatic feeding devices, which are manually loaded one by one, which also makes manual The labor intensity is high, and it cannot meet the requirements of batch testing in production. Even if there is a feeding device, it is simple to put all the pipettes to be tested into the hopper of the feeding device. The pipettes in the hopper are placed in a mess. It cannot meet the subsequent detection requirements, and the pipettes in the hopper are easy to fall from the outlet and cannot fall to the detection equipment. The outlet of the hopper is blocked; because the serological pipettes have different specifications and sizes, the existing serological pipette feeding devices are all simple and unified structures, which cannot be adjusted according to the different specifications of the serological pipettes. Regulatory

[0003] Therefore, the existing air-tightness testing equipment for serological pipettes has the problems of messy feeding, easy drop of the pipette to be tested, blockage of the feeding port, lack of adjustment and poor adaptability
