Description

technical field [0001] The invention relates to the technical field of precision processing equipment for light guide plates, in particular to a pattern processing equipment for light guide plates. Background technique [0002] In the current field of optical equipment processing, in order to change the side-illuminated light source from a line light source to a uniform surface light source, it is necessary to carry out precise pattern processing on the light guide plate that is compatible with the light source. With the continuous improvement of use requirements, People have also put forward higher requirements on the performance of the light guide plate pattern processing equipment. [0003] At present, the existing light guide plate pattern processing equipment usually includes a mobile platform respectively arranged on the Y-axis guide rail and a laser lens arranged on the X-axis guide rail. The laser beam is collected and refracted to the processing surface of the ligh...

Problems solved by technology

[0004] However, although the above-mentioned processing process can meet the basic processing needs of the light guide plate pattern, since its Y-axis variable speed motion and X-axis reciprocating motion require frequent acceleration and deceleration, the inertia generated during the frequent speed change process will increase the processing equipment. The machine body vibrates, which leads to an increase in the processing error of the light guide plate pattern and a decrease in processing accuracy; at the same time, the laser processing operation cannot be performed during the acceleration and deceleration time of the relevant components, the continuity of the processing process is poor, and the processing efficiency is low.
