Background technology
LCD screen is widely used in the numerous areas such as national defence, industry, family expenses, communal facility as main display device, at present, the detection of LCD screen adopts artificial visual to detect always, this detection mode has the drawbacks such as detection efficiency is low, loss is high, labour intensity is large, expense is high, and mass detection work can cause serious injury to detecting workman's eyesight in addition.Some poor short circuit just can be reported to the police and embody in the last moment of test machine scanning.On LCD circuit board as shown in Figure 1, there is electrode 1,2,3, during short-circuit test, will carry out (1,2) to three electrodes; (1,3); (2,3) pairwise testing, if electrode (1,2); (1,3); All not short circuits between (2,3), this LCD is qualified; If electrode 1,2, all not short circuits of electrode 1,3, short circuit between electrode 2,3, but scanning electrode 1,2, after electrode 1,3, instrument is not also able to do in time scan electrode 2 and 3, just test man opens frock, LCD to be taken out, and causes LCD short circuit undetected.And regard this LCD as non-defective unit and be sent to subsequent processing, finally stay and flow to client, suffer customer complaint and the return of goods, in waste money, affect corporate reputation.
Therefore, the detection of LCD screen needs a kind of deficiency that can overcome artificial visual detection, detecting fast and accurately LCD screen finished product has or not as follows: demonstration is opened circuit, short circuit, many sections and display comparison degree deviation, physical dimension deviation, the defects such as the dimensional discrepancy of sealing compound.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of New type LCD panel detection device, in order to solve the problems of the technologies described above.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of New type LCD panel detection device, comprises tester, machine frame, LCD plate, electricity suction lock, trigger switch; Described tester is connected with machine frame, and this machine frame comprises that frock renovates and machine frame base; Described machine frame is provided with electricity suction lock, and this electricity is inhaled to lock and comprised electricity suction lock base and iron locking closure, and wherein electricity suction lock base is connected with tester; Described tester is connected with trigger switch.
As preferably, the frock of described machine frame is renovated and is provided with iron locking closure; The machine frame base of this machine frame is provided with electricity and inhales lock base.
As preferably, described iron locking closure is corresponding with the position that electricity is inhaled lock base.
As preferably, described electricity is inhaled lock base and is provided with iron-core coil.
The utlity model has simple in structure, detect fast, accurately, yields advantages of higher.By electricity is installed on machine frame, inhale lock, it is corresponding with iron locking closure that electricity is inhaled lock base, and electricity is inhaled the energising of lock base simultaneously, and coil produces magnetic field, holds the locking closure of irony, and now just can not arbitrarily machine frame be opened and take out LCD plate, be locking-in state; Be completed, the voltage of lock base is inhaled in middle power-off, and magnetic field disappears, and iron locking closure acting force is disappeared, and transfers released state to, and test man just can open frock LCD is taken out.This device can overcome the deficiency that artificial visual detects, fast, accurately, entry detect LCD screen finished product have or not following as: show open circuit, the defect such as short circuit, many sections and display comparison degree deviation, improve LCD screen testing efficiency and automated production degree.
