Embodiment Construction
[0049] Aiming at the problem that there is no equipment for testing the flatness of raw materials and finished products of electronic screens in the prior art, the invention provides a flatness testing equipment.
[0050] The flatness detection device of the present invention is used to detect the flatness of the surface to be measured of the object to be tested, for example, to detect the flatness of the glass surface, and for another example, to detect the flatness of the screen surface, in other words, it can be used in the The glass is tested for flatness before the glass is assembled on the electronic product, and the screen formed by the glass can also be tested for flatness after the glass is assembled on the electronic product.
[0051] The flatness detection equipment includes an optical network device and a detection part 2, such as figure 1 As shown, the optical network device is used to provide an optical network 4, such as image 3 As shown, the optical network 4...

The invention discloses flatness detection equipment, a detection piece and a flatness detection method. The flatness detection equipment is used for detecting the flatness of the to-be-detected surface and comprises an optical network device and a detection piece. The optical network device is used for providing an optical network; the optical network is in a net shape formed by a plurality of staggered light rays, the detection piece at least comprises an abutting part and a shielding part, the abutting part is used for abutting against the surface to be detected, the shielding part is usedfor being arranged in the optical network, and the shielding part is constructed in the mode that when the abutting part abuts against the positions, with different flatness degrees, of the surface tobe detected, the effective shielding number of the shielding part to the light rays is different. According to the invention,, the detection piece is arranged in the optical network, the detection piece actually shields different numbers of light rays in the optical network due to different heights of detection positions, the height of the detection position can be obtained by shielding the number of the light rays in the optical network, the flatness detection equipment is simple in structure and low in preparation cost, and the flatness detection method is simple and easy to operate.
Description
technical field [0001] The invention relates to the technical field of screen quality detection, in particular to a flatness detection device, a detection piece and a flatness detection method. Background technique [0002] Nowadays, with the development of science and technology, the popularity of electronic products is getting higher and higher, especially the infrared touch devices. When the object blocks some infrared rays, the touch position is obtained. [0003] In the existing technology, on the one hand, in order to reduce the cost and increase the competitiveness of infrared touch devices, the transmitter lamp and receiver are changed from the original round head plug-in lamp beads to flat head plug-in lamp beads or flat head SMD lamps. bead, the emission power of the lamp tube decreases, and the position of the lamp tube in the lamp bead is closer to the glass; on the other hand, the thickness of the glass becomes thinner and thinner, and the thinner glass is easi...
