Nowadays, photo-alignment technology and products are also developing rapidly, and manufacturers are constantly improving their independent research and development capabilities to produce cost-effective products. The use of the outer drum structure ensures the feasibility of high precision effects in principle. The outer drum type photo-aligning machine is simple and reliable in structure, the core component precision is easy to control, and the light spot is closely imaged on the medium. Therefore, it is easier to achieve high-precision effects. This article will introduce the output resolution of the imagesetter.
The inspection was carried out in comparison with the row machine, but no obvious failure was found. Remove the upper cover of the cassette, open the photo-setting machine, and let the film enter the film manually. On the other hand, the hand-held motor of the photo-aligning machine automatically turns the wheel and finds that it is rotating, but the friction wheel of the collecting box The speed of rotation is slower. After shutting down, use your finger to move the wheel against the motorized wheel of the machine, and then add some resistance to the friction wheel of the box, and find that it does not rotate.
After careful observation, we can guess that this reason is caused by the long-term friction caused by the rotating wheel of the take-up motor and the friction wheel of the take-up box, which causes the rubber to age and wear, resulting in poor contact between the two rubber wheels. Generally, it can be adjusted by adjusting the sheet of the machine, and the elastic scale of the steel shrapnel on the back of the motor solves the fault, but we found that at this time, the elastic scale has been adjusted to the maximum extent. Therefore, it is only necessary to consider the winding motor and the film box friction rotating wheel to eliminate the malfunction.
Designers are designed to take into account factors such as the accuracy of the application components, tolerances, force distribution and balance compensation, and optimize to ensure the quality of the machine, each set of images arranged into the customer's hands are fully achieved Design accuracy requirements, high stability characteristics.
