detailed description

First, please refer to Figs. 3 to 5, the present invention includes: a frame body 50, which is composed of an inner frame body 51 and an outer frame body 52, and the outer ring wall of the inner frame body 51 and the outer frame body There is a gap between the inner ring walls of the body 52 to form an annular air flow channel 53, and an air extraction hole 54 is arranged on the outer frame body 52 opposite to the annular air flow channel 53, and the top surface of the outer frame body 52 is higher than the inner wall. Frame body 51 top surface; An air-tight plate 60, the periphery is fixed on this inner frame body 51 top surfaces, and this air-tight plate 60 can be the mesh plate that all meshes are blocked; An adsorption plate 70, the periphery is fixed on this outer frame body 52 top surface, and the adsorption plate 70 can be a net plate that blocks the mesh part area and forms the adsorption area 71 in the non-blocked area; A planar airflow channel is further formed between them, and the planar airflow channel formed by the air guide plate 80 communicates with the annular air flow channel 53, and the air guide plate 80 can be a mesh plate with all meshes unblocked.

Based on the above-mentioned constitution, the present invention can place the film and the panel to be pasted on the top surface of the adsorption area 71 of the adsorption (net) plate 70, and the annular airflow channel 53 and the air guide can be connected through the suction hole 54. The planar air flow channel formed by the plate 80 is sucked, and the panel and the film in the adsorption area 71 of the adsorption (net) plate 70 are adsorbed and positioned, and then the processing equipment 40 is placed on the bottom surface of the adsorption area 11 of the adsorption (net) plate 70 Apply pressure to carry out the action of sticking the film to the panel; yet, because the present invention is to make the air extraction space (annular air flow passage 53 plus the plane formed by the air guide plate 80) under the adsorption (net) plate 70 Shaped air flow channel) is minimized, only need to match the suction device of small horsepower to maintain the adsorption force of the adsorption area 71 of the adsorption (net) plate 70, which has the effect of greatly reducing the cost of air extraction equipment and operating costs; moreover , when adsorbing, because the adsorption (net) plate 70 will only produce a very small amount of deformation, the present invention has the effect of prolonging the service life of the net plate and improving the processing quality.
