Description

Automatic scoring device and automatic scoring method

Technical Field

The invention belongs to the technical field of examination paper detection in the education industry, and particularly relates to an automatic examination paper reading device and an automatic examination paper reading method.

Background

Examination paper examination is an intersection of multiple fields such as mechanical paper feeding and discharging mechanisms, education and culture, examination paper image recognition and the like. The purpose of batch examination of the test paper is achieved through automation and computer technology, and the method has important significance for the field of education.

At present, most of examination papers reading machines on the market are cursor examination machines, and the working principle of the cursor examination machines is as follows: the scribble content on the information card is identified, then transmitted to the computer, and then the paper is read on the computer by a teacher. The cursor reader has the following problems: cursor book readers and paper reading cards are expensive, cannot be widely popularized, and are particularly not suitable for small-scale examinations at ordinary times. Other types of examination paper reading machines on the market easily cause phenomena such as paper jam when the examination paper is discharged from a paper feeding machine, and have the problem of poor use experience.

Therefore, it is very important to design a device with small volume, light weight, low cost and high reliability.

10. An automatic scoring method of the automatic scoring device according to any one of claims 1 to 9, comprising the steps of:

step 1, drawing out a paper clamping mounting plate (3.1.1) outwards along a paper clamping guide rail (3.1.10), pulling out an outer paper clamping telescopic sleeve (3.1.8) below a paper clamping plate (3.1.5), and supporting the paper clamping plate (3.1.5); pulling out a rolling drawing plate (4.2.4);

placing the test paper on a paper clamping plate (3.1.5), and clamping the test paper by using the paper clamping plate (3.1.5);

step 2, the electromagnet tightly absorbs the electromagnet mounting rack (3.3.9), and the claw is loosened, so that the limit of the transmission shaft (3.3.5) is released;

the direct current motor drives the driving gear (3.3.1) to rotate, and the driving gear (3.3.1) drives the transmission gear (3.3.3) to rotate through the reduction gear (3.3.2);

when the transmission gear (3.3.3) rotates, the paper shaking and twisting square shaft (3.3.8) is driven to rotate by the paper shaking and twisting incomplete gear (3.3.7) and the braking incomplete gear cam (3.3.6); when the paper shaking and twisting square shaft (3.3.8) rotates, the paper shaking gasket (3.4.10) is driven to rotate, the plastic rotating shaft support (3.2.3) is pressed and loosened, and the function of paper shaking is realized;

meanwhile, when the paper shaking and twisting square shaft (3.3.8) rotates, the roller (3.4.4) is driven to rotate, the rubber roller (3.4.6) on the roller (3.4.4) rubs with the test paper to drive the test paper to be transmitted, and the paper twisting function is realized;

when the transmission gear (3.3.3) rotates, the transmission shaft (3.3.5) is driven to rotate; when the transmission shaft (3.3.5) rotates, the transmission shaft (3.3.5) drives the transmission roller (3.4.8) to rotate, and the transmission roller (3.4.8) and the transmission driven roller (3.4.9) rotate up and down relatively to drive the twisted test paper to be transmitted forwards;

step 3, when a twisted test paper is transmitted forwards and passes through the camera module (2), the camera module (2) takes pictures and identifies the test paper;

step 4, starting a roll transmission motor, driving a roll transmission driving gear (4.1.1) to rotate by the roll transmission motor, and driving a roll transmission driven gear (4.1.2) to rotate by the driving gear (4.1.1) so as to drive a roll transmission shaft (4.1.3) to rotate; when the roll conveying shaft (4.1.3) rotates, the roll conveying roller (4.1.4) is driven to rotate; the paper conveying roller (4.1.4) and the paper conveying driven roller (4.1.7) rotate up and down relatively to drive the test paper after being photographed and identified to be conveyed forwards;

and 5, finally, the test paper falls on the pulled-out rolling drawing plate (4.2.4) to realize the rolling function.
