The core cover plate 114 is provided with a circumferential positioning boss, which cooperates with the tightening screws 113 arranged around the circumferential positioning boss to ...

Embodiment 2

[0069] The main difference between this embodiment and Embodiment 1 is that: the structure of the heat dissipation channel in the ED core protection device is different. The difference between this embodiment and Embodiment 1 will be mainly explained below.

[0070] Such as Figure 6-7 As shown, the ED core protection device of this embodiment includes an air cavity cover 115, a core cover 114 and a support 107 arranged sequentially from top to bottom, and the ED core 109 is arranged on the core cover 114, and is supported horizontally by the first baffle plate 121 and the second baffle plate 122 matched with the core cover plate 114; The air intake chamber 123 inside 107 is communicated; further, the core body cover plate 114 is provided with a core wiring chamber 118 communicated with the air intake chamber 123 .

[0071] Therefore, the flow direction of the heat dissipation gas in the heat dissipation channel in this embodiment is: compressed gas or other cooling gas enter...

Embodiment 3

[0074] The difference between this embodiment and Embodiments 1 and 2 lies in that the structure of the heat dissipation channel in the ED core protection device is different. The difference between this embodiment and Embodiments 1 and 2 will be mainly explained below.

[0075] Such as Figure 8 to Figure 10 As shown, the ED core protection device of this embodiment includes a core cover plate 114, a support member 107 and a bottom plate 124 arranged sequentially from top to bottom, wherein the ED core 109 is arranged on the surface of the support member 107 and Fixed by the core cover plate 114 , the pipe joint 106 is arranged at the bottom of the bottom plate 124 , and the temperature sensor 108 is installed on the side of the bottom plate 124 , the support member 107 or the core cover plate 114 .

[0076] The heat dissipation channel of the ED core protection device includes: the air inlet chamber 123 formed by the base plate 124 and the support member 107 and the core wir...

Abstract

The invention discloses an ED core protection device and a polarization detection module of a liquid crystal screen optical alignment device, comprising: a support, a core cover and a temperature sensor for detecting the temperature of the ED core, wherein the support and the core The cover plates together form an installation main body for accommodating and fixing the ED core, a heat dissipation channel is arranged in the installation main body, a tapered hole is opened in the center of the core cover plate, and the tapered hole The center coincides with the center of the ED core. The ED core protection device of the present invention is provided with a heat dissipation channel inside to ensure that the ED core quickly reaches a thermally stable state under strong light conditions, and improves measurement efficiency and accuracy; the present invention is used in conjunction with the core cover plate and the pinhole plate , so that the light transmission area is reduced, and the use of different pinhole plates can reduce the light transmission surface to a diameter of 1mm or less; by replacing the core cover with a different cone angle, the measurement accuracy of the light intensity within a certain range of incident angles can be improved. sex.

Description

technical field [0001] The invention relates to the field of integrated circuit manufacturing, in particular to an ED core protection device and a polarization analysis module of an optical alignment device of a liquid crystal screen. Background technique [0002] In light source equipment using high power and strong light, it is often necessary to detect the specific light intensity of a certain area or point of interest, such as liquid crystal screen optical alignment equipment. The detection of light generally uses the directly purchased ED (energy sensor); considering that under strong light conditions, the working environment temperature of the ED is high, and the light area directly irradiated on the ED core is too large. The sensor is easy to fill the range, which affects the measurement accuracy, and the range of incident angle of light is too large. [0003] The key detection equipment in the liquid crystal screen optical alignment equipment is the polarization ana...
