Light curtain is a safety protection device based on photoelectric induction principle. Light curtain dispensing is mainly the application of combination reinforcement of internal parts. Because light curtain has certain transmittance, it can be used for bonding reinforcement with ultraviolet UV glue. It is feasible for positioning and controlling glue volume of UV glue dispensing machine. It is necessary to install UV needle barrel and glue dispensing adapter to control precise dispensing and fixing of light curtain components in fully automatic mode The actual situation is similar to the application of transparent materials such as touch screen fitting.

The dispensing process of light curtain components
There are some transparent positions outside the safety light curtain. If the reinforcement seal can be coated with some UV glue at this distance, the glue can be coated to the sealing position by precise quantitative control after setting the path of the UV glue dispenser. The particularity of the sealant needs ultraviolet light to promote the curing efficiency. After the light curtain dispensing, the curing efficiency can be accelerated by ultraviolet light, and the storage black glue dispensing syringe needs to be accelerated. The fixed quality can be controlled with dispensing adapter at the same time. If it needs to be disassembled again, the UV glue adhering to the light screen needs to be removed in a special way before it can be re-applied. The same mobile touch screen should be precisely controlled to avoid excessive glue leakage.
Precision dispensing of light curtain

The choice of UV glue dispenser for filling and reinforcing components of light curtain has high execution precision and high consistency in batch execution. This is the main reason for batch production selection of light curtain dispensing at this stage. The contract sample of touch screen dispensing can conform to the use of UV glue dot bonding, control the moving alignment of black dispensing syringe and dispensing adapter, so as to precisely control the amount and location of glue. This mode controls the precision effect, and the frequency of removing UV glue will be reduced.

The aligned curtain has a firm and stable application effect after dispensing. The finished product is more stable and of good quality. The frequency of removing and repairing UV glue is reduced by a complete coating method.
