Abstract

The invention discloses an edge-tearing machine for an aperture mask, belonging to a manufacturing device for a flat television and comprising a stander (1). The invention is characterized in that an upright post(2) is arranged on the stander (1); a linear bearing(3) is arranged on the upright post(2); the linear bearing(3) is connected with a movable frame(4); an alnico post (5) is arranged at the upper end of the movable frame(4); the alnico post(5) passes through the guide hole of a work bedplate (6) and then touches an aperture mask(7); the work bedplate (6) is fixed at the upper end of the upright post(2); keep plates (8) which are used for pressing the edges of the aperture mask(7) are hinged at the two edges of the bedplate; a positioning pin(9) which corresponds to a positioning hole on the aperture mask (7) is arranged on the work bedplate (6); the aperture mask(7) is positioned on the work bedplate (6) through the positioning pin(9) and the keep plates (8); a power device(10) is arranged in the stander (1); an eccentric wheel(11) is arranged on an output shaft of the power device(10); the eccentric wheel(11) leans against a bearing (12) arranged at the lower part of the movable frame(4). The invention has the advantages of simple structure, good edge-tearing effect and low cost.

Description

technical field [0001] The invention relates to a flat TV manufacturing equipment, in particular to a flat TV shadow mask processing equipment, in particular to a shadow mask edge tearing machine. Background technique [0002] As we all know, the shadow mask is an important display part of the plasma flat panel TV. It is located between the front and rear substrates, and its shape is as follows: figure 1 As shown, it is mainly composed of process edge 101, pre-etching groove 102, positioning hole 103, working part 104 and so on. The process side 101 is used for the subsequent process, and after the process side is separated, it can be obtained as follows figure 2 Finished shadow mask shown. The process side must be removed after the corresponding process is completed. At present, the method of trimming is usually used to separate the process side. Because of the large size of the shadow mask, the manufacturing requirements of the trimming equipment are high and difficult....
