Problems solved by technology

[0002] The automatic darkening welding mask is a new type of welding mask, which 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. However, the aging problem of automatic darkening welding masks has always been a major difficulty, so most manufacturers omit the aging step when producing automatic darkening welding masks, making the aging of automatic darkening welding masks The unqualified rate of production has always been high, causing many losses to users and factories

no. 1 approach ）

[0018] Such as figure 1 As shown, the moving part 1 is an assembly line conveying equipment, and a transparent pure polyurethane PU conveyor belt can be used. The triggering part 2 uses a radiation light source, such as an infrared bulb or an infrared LED. The automatic darkening filter 5 of the welding mask is placed on the moving part 1. The moving part 1 can move at a constant speed according to the set direction and speed, and drive the automatic darkening filter 5 of the electric welding mask placed on it to move accordingly, and the triggering part 2 can send out changing infrared light according to the set mode, Its on-time (that is, the time when the power is turned on and emits infrared light) can be set arbitrarily between 1ms and normally open, and its off-time (that is, the time when the power is turned off without infrared light) can be set arbitrarily between 1ms and normally closed; In this way, the automatic darkening filter 5 of the welding mask that completed...

no. 2 approach ）

[0020] Such as figure 2 As shown, the moving part 1 is an assembly line conveying equipment, and a chain conveying line with adjustable width can be used. The light source part 20 and the light source control part 21 form the trigger part 2 (not shown in the figure), and the automatic darkening filter 5 of the welding mask is placed On the moving part 1; the moving part 1 can do intermittent movement according to the set direction and speed, and drive the automatic darkening filter 5 of the electric welding mask placed on it to move accordingly. The infrared LEDs of the segment, the light source control part 21 can respectively control the above-mentioned infrared LEDs that are connected into several segments to emit changing infrared light according to the set mode; For the various working parameters of the optical filter 5, if any product is damaged in the aging process, it can be picked out through this step to ensure the pass rate of the product.

no. 3 approach ）

[0022] Such as image 3 As shown, the moving part 1 is an assembly line conveying device, and a Teflon conveyor belt can be used. The temperature-controllable blowing device 40 is installed on the casing 41 to form a temperature control part 4. Each welding mask aging equipment includes at least one temperature control part 4 , the moving part 1 passes through the temperature control part 4, the light source 22 can adopt an illumination source, such as an incandescent lamp, and the temperature-controllable blower 40 can adopt a temperature-adjustable hot air blower or a cold air blower for controlling the temperature in the temperature control part 4. Temperature: the automatic darkening welding mask 6 is placed on the moving part 1, and the aging process is carried out during the movement therewith, and at the same time, because the ambient temperatures flowing through different temperature control parts 4 are different, better aging can be achieved Effect.

Abstract

The invention provides an aging equipment and aging method for electric welding masks, which include a moving part (1) and a trigger part (2). The moving part (1) makes the automatic darkening welding mask (not shown) or The automatic darkening filter (5) of the welding mask moves according to the set method; the trigger part (2) triggers the above-mentioned automatic darkening welding mask (not shown) or the automatic darkening filter (5) of the welding mask according to the set method ) to make it respond; the configuration of the moving part (1) and the triggering part (2) ensures that the automatic darkening welding mask (not shown) or the automatic darkening filter of the welding mask placed on the moving part (1) (5) can be triggered by the triggering part (2); thus making the online aging of the automatic darkening welding mask possible, improving the production pass rate and reducing losses.

Description

technical field [0001] The invention relates to an aging device and an aging method for an electric welding mask, in particular to an equipment and a method for online aging of an automatic darkening welding mask and an automatic darkening filter of the electric welding mask. Background technique [0002] The automatic darkening welding mask is a new type of welding mask, which 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. However, the aging problem of automatic darkening welding masks has always been a major difficulty, so most manufacturers omit the aging step when producing automatic darkening welding masks, making the aging of automatic darkening welding masks The unqualified rate of production has always been high, which has brought many losses to users and factories. Contents of the invention [0003] The technical problem...
