How to judge the quality of the LED stage lights?

At present, the market on the LED stage lights more and more intense competition, but also filled with a variety of brands, so how to judge the quality of the LED stage lights?

A strict examination of LED raw materials of the solid crystal station

1 chip: the main performance for the pad pollution, chip breakage, chip cutting size, chip cutting tilt, etc.. Preventive measures: strict control of incoming inspection, found that the problem requires suppliers to improve.

2 support: mainly for the deviation. The size and C size is too large, support color rust, deformation of support etc.. Incoming material is a supplier problem, should inform the supplier to improve and strictly control the feed.

3 silver glue: the main performance of the silver glue viscosity is bad, the use of more than, storage conditions and thaw conditions and the actual standard does not match. In view of the viscosity of silver glue, generally after the project is put into production will not have too many problems, but it is not to say that the kind of silver glue is the best, if found to have adverse effects, the project will be re evaluated. While other terms of use, storage conditions, thawing conditions are artificially controlled, as long as strictly in accordance with SOP operations, there will not be too many problems.

Two, reduce adverse human factors

1 operators of illegal operations: such as not wearing gloves, silver glue from the freezer after thawing without directly on the line, and the staffs don't press SOP, or on the machine operation is not skilled have influence on solid crystal quality. Preventive measures: foreman to strengthen management, staff according to SOP operations, quality assurance personnel to strengthen the audit, the machine is not skilled personnel to strengthen education and training, no official posts are not allowed.

2 maintenance personnel improper adjustment: the strategy is to improve the technical level. For example, the height of the crystal, the height of the crystal, the height of the thimble, the setting of some delay time, the parameters of the motor, the setting of the worktable parameters, etc., should be adjusted to the best condition according to the standard.

Three, to ensure that the machine does not appear on the main aspects of the main performance of the machine parts or parts of the mechanical structure, such as the understanding of the adverse effects of the system on the quality of solid crystal. Make sure the machine functions are normal.

Four, the implementation of the correct adjustment method

The 1 spot is not good: Countermeasures -- to set the spot, ensure 3.1.

The 2 parameter adjustment improper: for example: picklevel, bondlevel, ejectorlevel, delay time, motor parameters, solution steps and reducing far more still can be done, but the result is completely different. The same is the thimble height, when the suction can not afford the chip, a loud parameter, but not to consider whether the thimble dull or broken, resulting in the breakage of the chip, theta angle offset etc.. Delay time and motor parameters are also the same, with bad, welding arm action will not be the same, resulting in abnormal quality.

3 improper setting of two values: Countermeasures - reset the value of two.

4 machine standards are inconsistent. For example: when adjusting the glue, the glue spring to death, dispensing head a little bit of flexibility are not, how to adjust the parameters are useless. Again, such as the adjustment of the hook claw hook hook up and down the hook and pop displacement if not adjusted according to the standard, it is easy to cause the material and deformation, etc.. Another example is the welding arm pressure, if not adjusted according to the standard, will also affect the quality of solid crystal, but also how to tune the parameters are not good tune.

Five, master the process

1 silver glue tank cleaning is regular cleaning.

2 the choice of silver glue is reasonable.

3 whether the workers wear gloves and masks.

4 baking conditions, time and temperature of solid crystal materials.
