Problems solved by technology

[0004] As a new type of welding mask, the automatic darkening welding mask is composed of a welding mask and an automatic darkening filter. The window part uses LCD, and the light transmittance of the LCD can be controlled by the control circuit in the welding mask. Compared with, there are many advantages; but for a long time, the aging problem of traditional testing of automatic darkening welding filters in the existing technology is a major difficulty, so most manufacturers omit the aging step when producing automatic darkening welding masks. The production failure rate of automatic darkening welding masks has always been high, which has brought many losses to users and factories

Embodiment 1

[0030] Such as Figure 1-2 As shown, a kind of welding lens aging test method provided in this embodiment includes the following steps,

[0031] Step 1. The operator first puts the tooling plate of the workpiece to be detected on the work frame 1, then positions the workpiece to be detected by the positioning block 2, and then presses the start switch 3. At the same time, it is located in the work frame 1 The light source 16 is turned on;

[0032] Step 2: Turn on the lifting cylinder 4 to make the lifting cylinder 4 perform a downward movement, and the detection mechanism camera obscura 5 arranged on the lifting cylinder 4 also moves downward along with the lifting cylinder 4 until the detection mechanism camera camera 5 and the workpiece to be detected are in a closed state ;

[0033] Step 3. The operation button 6 controls the movement of the pneumatic gripper 7, so that the shaft end of the pneumatic gripper 7 clamps the potentiometer 8 and rotates at a certain angle. At ...

Embodiment 2

[0040] Such as Figure 1-2 As shown, a kind of welding lens aging test method provided in this embodiment includes the following steps,

[0041] Step 1. The operator first sets the tooling boards of several workpieces to be detected on the same horizontal plane and puts them on the work frame 1. A certain distance is set between each two adjacent workpieces to be detected, and then through the positioning stopper 2. Position the workpiece to be detected, and then press the start switch 3. At the same time, the light source 16 located in the work frame 1 is turned on, and the light source 16 in the above is an independent light source;

[0042] Step 2, open the lifting cylinder 4 to make the lifting cylinder 4 perform a downward movement, and the detection mechanism dark box 5 arranged on the lifting cylinder 4 also moves downward along with the lifting cylinder 4. At the same time, the lifting guide rails 15 on both sides of the work frame 1, Cooperate with the lifting cylind...

Abstract

The invention discloses a welded lens aging testing method. An operator firstly places a tooling plate of a to-be-detected workpiece onto a workbench; then positioning is carried out by a positioningcheck block; then a starting switch is pressed down; a lifting cylinder takes a descending action; a detection mechanism camera bellows also takes a descending action along with the lifting cylinder,until the detection mechanism camera bellows and the to-be-detected workpiece are in a closed state; a pneumatic clamping jaw clamps a shaft end of a potentiometer to rotate by a certain angle, and atthe moment, the potentiometer is started up and is at a minimum position; an industrial camera lens carries out shooting detection on the to-be-detected workpiece; the pneumatic clamping jaw clamps the shaft end of the potentiometer to continuously rotate by a certain angle, until the potentiometer is positioned at a maximum position; second shooing detection is carried out; the pneumatic clamping jaw clamps the shaft end of the potentiometer to reversely rotate by a certain angle until the potentiometer is closed; then third shooting detection is carried out; finally, the pneumatic clampingjaw is released by a button, the lifting cylinder moves back, and each mechanism on the workbench is reset. A reject ratio of production is greatly reduced, and loss of a user and a factory is reduced.

Description

technical field [0001] The present invention and the field of microelectronic technology, in particular, relate to a method for testing the aging of welding lenses. Background technique [0002] In the process of metal welding, strong electromagnetic waves (including visible light and invisible light) will be generated, which will burn the welder's eyes, so it is necessary to install a protective device on the protective mask to protect the eyes. The early protection method was to install a piece of black glass on the protective mask. [0003] With the improvement of welding requirements and technological progress, automatic darkening welding filter came into being. The automatic darkening welding filter uses the principle of photoelectric induction to change the liquid crystal from a bright state to a dark state at the moment of receiving arc light, and the welding is over. Afterwards, it automatically switches from a dark state to a bright state, thereby protecting the us...
