Problems solved by technology

[0004] However, in the prior art heating cavity shown in FIG. 1 b, when the closing cover 30 is removed from the opening 11 of the cavity, part of the volatilized solvent will condense on the inner surface 31 of the closing cover 30 due to the temperature drop.
When the closing cover 30 moved back to the cavity opening 11, the solvent condensed on the inner surface 31 of the closing cover 30 splashed onto the substrate in the heating cavity 10 due to vibration, causing the black stripe matrix of the process to be missed (Black MatrixLoss), the reasonable rate of production of the circuit array of the liquid crystal display is reduced

Embodiment Construction

[0021] The invention provides a heating cavity device. In a preferred embodiment, the heating chamber device is used for the heating process of the liquid crystal display circuit array. However, in different embodiments, the heating chamber device can also be used in the heating process of circuit arrays of other electronic products.

[0022] In the embodiment shown in FIG. 2 , the heating chamber device 900 includes a heating chamber 100 , a closing cover 300 and a cleaning device 500 . The heating chamber 100 has a chamber opening 110 . The closure lid 300 has an inner face 310 . The closing cover 300 can be located at the cavity opening 110 for covering the cavity opening 110 . In the process of liquid crystal display circuit array, the photoresist coated on the substrate must first be volatilized by heating. When the heating chamber device 900 is performing a heating process, part of the solvent will be filled in the heating chamber 100 due to heating volatilization. ...

Abstract

The invention relates to a heating cavity device used for circuit array programming of an LCD. The heating cavity device comprises a heating cavity, a sealing cover and a cleaning device. The heating cavity is provided with a cavity hatch, and the sealing cover is provided with an inner face and can be positioned at the hatch of the cavity to cover the hatch of the cavity. The cleaning device is provided with a cleaning face, and the sealing cover contacts the cleaning face when the sealing cover withdraws the cavity outlet. The cleaning device is further provided with a fixing part for fixing the cleaning face. The sealing cover further comprises a driving device used for driving the sealing cover to be positioned at the cavity outlet. The deriving device consists of a cylinder and a cantilever, and two ends of the cantilever are respectively connected with the cylinder and the sealing cover. When the cylinder drives the cantilever, the sealing cover is interlocked with cantilever.

Description

【Technical field】 [0001] The invention relates to a heating cavity device, in particular to a heating cavity device used in the liquid crystal display circuit array manufacturing process. 【Background technique】 [0002] Liquid Crystal Displays (LCDs) are widely used in various electronic products such as computers, televisions, and mobile phones. The circuit array (array) of the liquid crystal display is one of the important components of the liquid crystal display. The production rationality of the LCD circuit array directly affects the efficiency and manufacturing cost of the LCD. [0003] During the process of manufacturing the circuit array of the liquid crystal display, the photoresist coated on the substrate must first be volatilized by heating. As shown in FIG. 1a , the prior art heating chamber, the substrate (not shown) is sent into the heating chamber 10 through the opening 11 of the heating chamber to evaporate the solvent in the photoresist. During the heating...
