Automatic cropping, sorting and ranking device for test paper

Abstract

The invention discloses an automatic cropping, sorting and ranking device for test paper. The automatic cropping, sorting and ranking device comprises a rack and further comprises a drive motor, a cropping mechanism, a ranking mechanism, a positioning tool and a sorting mechanism, all of which are arranged on the rack. The drive motor drives the cropping mechanism and the ranking mechanism througha cam. The cropping mechanism comprises a cutter, a cropping connecting rod and a cropping transmission assembly. The ranking mechanism comprises a track, a ranking connecting rod and a side pushingblock. The positioning tool comprises a positioning carrier and a positioning drive set, and the positioning drive set drives a positioning cavity in the positioning carrier to be in butt joint with the tail end of the track. The sorting mechanism comprises a CCD camera and a camera assembly arranged on the rack. The CCD camera is arranged on the camera assembly. By means of the automatic cropping, sorting and ranking device, cut-off products can be directly ranked, positioning is accurate and tidy, the automatic cropping, sorting and ranking device can be directly guided into an automatic production line to be applied without manual intervention, actions are simple and reliable, synchronism is good, the speed is high, and OK products and NG products can be sorted.

Description

technical field [0001] The invention relates to the field of test paper cutting, in particular to an automatic cutting, sorting and sorting device for test paper. Background technique [0002] In the test paper cutting industry, especially in the medical test paper cutting industry, the entire test paper is cut into narrow strips of 1-3 mm. Automatic cutting machines are widely used. The common cutting methods of cutting machines are: Upper and lower knife cutting, upper single knife cutting, hob cutting, etc. The cutting drive methods of the cutting machine include motor drive, cylinder drive, etc. Among them, the cutting machine driven by a motor and single-knife cutting is widely used because of its fast speed and simple and convenient tool replacement. [0003] Although the speed of the cutting machine driven by the motor and the upper single-knife cutting is fast, there are several shortcomings: (1) The state of the test paper after cutting cannot be effectively contro...

AI Technical Summary

Problems solved by technology

[0003] Although the speed of the cutting machine driven by the motor and the upper single-knife cutting is fast, there are several shortcomings: (1) The state of the test paper after cutting cannot be effectively controlled. Most of the receiving methods are to drop the product directly on the In the receiving box or turnover box, the finished materials are scattered and need to be sorted and collected manually; (2) Most of the cutting machines on the market exist in the form of stand-alone offline, which is difficult to import into a fully automated production line; ( 3) In the transformation of the automatic production line, most of the arrangements after cutting are carried by cylinders and vacuum adsorption. Such a structure is complex and costly, and the reliability is poor, and the speed is also greatly reduced; (4) The traditional cutting is only according to the established The specifications are cut off, and the OK and NG products cannot be sorted out, especially for the first NG material and the middle NG material, which cannot be sorted in time, and can only be sorted manually after all the cutting is completed.
