Description

Technical Field

[0001] This invention relates to the field of thermal sensor technology, and in particular to an intelligent thermal sensor device for the production of LCD panel ovens. Background Technology

[0002] In the manufacturing process of LCD panels, the oven is an indispensable key piece of equipment used for drying, curing and other processes. In these processes, precise temperature control plays a decisive role in the quality and performance of the LCD panel. If the temperature inside the oven is too high, it may cause denaturation of the liquid crystal material and damage to the panel structure; if the temperature is too low, curing will be incomplete, affecting the display effect and lifespan of the panel. Therefore, accurate and real-time monitoring of the temperature inside the oven has become one of the core elements to ensure the production quality of LCD panels.

[0003] However, there are some shortcomings in the current design of oven thermal sensors: First, traditional thermal sensors mostly use bolts to fasten circular metal plates. This installation structure has the drawback of complicated installation and disassembly processes during equipment debugging and maintenance, requiring a lot of time for repeated operations, which affects the efficiency of equipment installation and the convenience of subsequent maintenance. Secondly, existing thermal sensors lack structures to enhance airtightness. After prolonged use, gaps may appear between the thermal sensor and the oven, which can damage the sealed environment inside the oven, leading to heat loss and the intrusion of external impurities. This not only reduces production efficiency but may also cause fluctuations in product quality. Summary of the Invention

[0004] To address the above problems, one objective of this invention is to overcome these shortcomings, and more specifically, to provide an intelligent thermal sensor device for the production of LCD panel ovens, which can improve the efficiency of installing and disassembling the thermal sensor on the oven, and also ensure the airtightness of the thermal sensor and the oven installation location.

[0034] The specific usage and function of this embodiment are as follows: In this invention, such as Figures 1 to 8 As shown, before use, the substrate 201 is first fixedly installed in the designated position of the LCD panel oven via the ear plate 202, so that the inner groove 203 in the substrate 201 is connected to the inside of the oven. Then, the connecting wire harness 102 is connected to the intelligent detection equipment to realize the connection between the movable part 1 and the detection system. The external connector 105 is screwed onto the mounting end 104 of the sensor body 101. When installing the sensor body 101, the sensor body 101 is inserted into the inner groove 203 in the substrate 201, so that the slot 1052 on the external connector 105 engages with the locking block 2041 on the slider 204. At this time, the locking block 2041 locks the external connector 105 with the slot 1052 and fixes the sensor body 101 in the inner groove 203.

At the same time, the probe 103 passes through the top ring 205 and extends into the oven to detect the temperature. When it is necessary to detect the temperature of different height areas in the oven, another set of sensor bodies 101 can be inserted into the inner grooves 203 at different positions on the substrate 201. During the operation of the equipment, the probe 103 collects the temperature data in the oven in real time and transmits it to the intelligent detection equipment through the connecting wire harness 102. If disassembly and maintenance are required, the rectangular block on the front side of the slider 204 is moved so that the slider 204 slides along the guide rod 2042 in the inner groove 203. The locking block 2041 separates from the locking groove 1052 and loses the limitation of the outer connector 105. At this time, the sensor body 101 can be removed from the substrate 201.
