Embodiment Construction

[0022] Please refer to figure 2 , a cutter assembly 20 for cutting the protective film of the touch screen of the present invention includes a cutter 21, a first guide post 22, a second guide post 23, an electromagnet 24, a knife seat 25, a magnetic block 26, An ejector 27 , a knob 28 and a bearing 29 . The cutter assembly 20 can precisely adjust the cutting pressure of the cutter 21 so that the cutting pressure of the cutter 21 is between 1-20 grams.

[0023] The head of the cutting knife 21 has a cutting edge 212 . The blade 212 is in the shape of an arc, such as Figure 4 shown.

[0024] The electromagnet 24 can generate a magnetic force for attracting the tool seat 25 when energized. The greater the current, the greater the magnetic force generated by the electromagnet 24.

[0025] The knife seat 25 includes a first guiding portion 252 , a second guiding portion 254 and a mounting portion 256 . The installation portion 256 defines a through hole 258 , the through ho...

Abstract

The invention discloses a tool component for cutting a touch screen protection film. The tool component comprises a cutter, a first guide column, a second guide column, an electromagnet, a tool apron, a magnetic block, an elastic ejector and a knob. The first guide column and the second guide column are parallelly arranged at intervals, the tool apron comprises a first guide portion, a second guide portion and a mounting portion, the first guide portion and the second guide portion penetrate the first guide column and the second guide column respectively, the mounting portion is provided with a through hole, the cutter, the magnetic block, the elastic ejector and the knob are arranged in the through hole, the magnetic block attracts the cutter so that a cutting edge of the cutter downwardly extends out of the through hole, the elastic ejector is elastically ejected between the magnetic block and the knob, the knob is connected with the mounting portion in a threaded manner, the electromagnet generates magnetic force in electrification and attracts the tool apron to move downwards, and the cutting edge of the cutter is pressed on the touch screen protection film. The pressure of the cutter is controlled by adjusting current and can be accurately controlled, and cutting effects are ensured.

Description

technical field [0001] The invention relates to a cutter assembly for cutting a protective film of a touch screen. Background technique [0002] Please refer to figure 1 The touch screen 10 includes a glass substrate 12 and electrodes 14 disposed on the upper surface of the glass substrate 12 , and the upper surface of the touch screen 10 is covered with a layer of PE protective film 16 . The glass substrate 12 has a thickness of 0.33-1.1 mm; the electrode 14 has a thickness of 20-50 nanometers; and the PE protective film 16 has a thickness of 30-60 microns. During the production process, the PE protective film 16 needs to be cut to remove the PE protective film 16 around the touch screen 10 , so that subsequent processing such as electroplating can be performed around the touch screen 10 . [0003] During cutting, if the tool pressure is too high, the electrode 14 will be cut off directly, and if the tool pressure is too low, the protective film 16 cannot be cut off. Sin...
