Abstract
Description
Technical Field
[0001] This utility model relates to the field of display panel manufacturing, and in particular to a developing device used in the process of display panel manufacturing. Background Technology
[0002] During the manufacturing process, display panels need to go through processes such as film formation and development. The display panels to be processed are placed in a developing machine, which provides an environment where air can flow. After a period of time, the display panels are taken out and then subjected to subsequent etching and other processes.
[0003] In existing developing machines, a sealed cover is typically installed above the main body of the machine during the developing process. This can lead to an imbalance where the air intake exceeds the exhaust, causing abnormal airflow. This gas can then carry developer solution, which splashes onto the cover and drips down, resulting in display panel malfunctions. To avoid these airflow issues, the cover is usually moved to expose the machine body, allowing for air circulation. However, this circulation uses ordinary air, which cannot be guaranteed to be clean. Furthermore, moving the cover can cause developer solution to splash, and since developer solutions are generally highly corrosive and can severely damage human skin, this could injure operators.
[0004] Therefore, how to prevent developer splashing to ensure operator safety, and further improve the cleanliness of gas flow and increase production yield are urgent problems to be solved. Utility Model Content
[0005] This invention provides a developing apparatus to solve the above-mentioned technical problems.

[0021] To more clearly illustrate this utility model, the preferred embodiments and accompanying drawings will be used for further description. Similar components in the drawings are indicated by the same reference numerals. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of this utility model.
[0022] Please refer to Figures 1 to 3 , Figure 1 The diagram shown is a structural schematic of the developing apparatus of this utility model. Figure 2 The image shown is a top view of the cover of this utility model. Figure 3 This is an exploded view of the first side plate, filter screen, and first baffle plate of this utility model. Figures 1 to 3As shown, this utility model proposes a developing apparatus 100, which includes a stage 10, a developing machine body 20, a cover 30, a first baffle plate 40, and a filter 50. The stage 10 has a first through hole 11. The developing machine body 20 is disposed below the stage 10 and within the vertical projection range of the first through hole 11. The cover 30 is disposed above the stage 10 and opposite to the developing machine body 20. The cover 30 includes a first side plate 31, a second side plate 32, a third side plate 33, and a fourth side plate 34 that are connected to each other. The first side plate 31 is opposite to the third side plate 33, and the second side plate 32 is opposite to the fourth side plate 34. The first side plate 31 has a first opening 311. The first baffle plate 40 is disposed on the first side plate 31 corresponding to the first opening 311, and the first baffle plate 40 is movable relative to the first side plate 31. The filter 50 is fixedly connected to the first side plate 31 and covers the first opening 311.
[0023] The developing apparatus 100 of this invention has a first opening 311 on the first side plate 31 of the cover 30. In practical applications, the operator stands in front of the cover 30 (at the second side plate 32 or the fourth side plate 34). The first opening 311 is located on the first side plate 31, that is, on the side of the cover 30. The size of the opening can be adjusted by a movable first baffle 40 to allow gas flow. The cover 30, although it has a first opening 311, does not need to be too large, to prevent developer from splashing and ensure operator safety. The filter 50 filters the gas entering the developing machine body 20, improving the cleanliness of the gas. Furthermore, during the developing process, the operator's standing position can be different from the opening position. Even if developer splashes out through the first opening 311, it will not cause injury to the operator, further ensuring operator safety.
[0024] In one embodiment, the cover 30 further includes a top plate 35, which is connected to the first side plate 31, the second side plate 32, the third side plate 33, and the fourth side plate 34. The top plate 35 is farther away from the developing machine body 20 than the first side plate 31, the second side plate 32, the third side plate 33, and the fourth side plate 34, so that the cover 30 has a single-sided opening structure and covers the developing machine body 20 below. The first side plate 31, the second side plate 32, the third side plate 33, and the fourth side plate 34 are connected to form a second through hole 36. When the cover 30 covers the stage 10, the first through hole 11 of the stage 10 and the... The second through holes 36 of the cover 30 are interconnected. The first through hole 11 has a first projection range, and the second through hole 36 has a second projection range. The first projection range is located within the second projection range. That is to say, when the cover 30 covers the stage 10, the second through hole 36 of the cover 30 can completely expose the developing machine body 20 below. That is, the developing machine body 20 is located within the vertical projection range of the cover 30. There is no object blocking the developing machine body 20 and the cover 30, so that the developing machine body 20 is completely blocked by the cover 30 during operation, and there will be no splashing of developing solution.
[0025] like Figure 3 As shown, a filter screen 50 is also provided on the first side plate 31 corresponding to the first opening 311. The filter screen 50 is fixedly connected to the first side plate 31 and completely covers the first opening 311. That is, the area of the filter screen 50 is slightly larger than the area of the first opening 311. This ensures that the air entering the working space of the developing machine body 20 through the first opening 311 will first pass through the filter screen 50. If there are fine particles in the air at this time, they will be blocked by the filter screen 50, ensuring the cleanliness of the air finally entering the working space of the developing machine body 20. This can prevent the display panel from being contaminated by the air entering from the outside during the developing process and improve the production yield. In practical applications, the first side plate 31 can be provided with multiple mounting holes corresponding to the filter screen 50. The filter screen 50 can be fixedly connected to the first side plate 31 by the cooperation of bolts and nuts. However, this is not a limitation; the filter screen 50 can also be fixedly connected to the first side plate 31 by means of tape or other methods. The filter screen 50 can be provided on the outer surface or inner surface of the first side plate 31.
[0026] In one embodiment, the first baffle plate 40 is disposed on the outer side of the first side plate 31, and the filter screen 50 is also disposed on the outer surface of the first side plate 31 and covers the first opening 311; or, the first baffle plate 40 is disposed on the inner side of the first side plate 31, and the filter screen 50 is also disposed on the inner surface of the first side plate 31 and covers the first opening 311. However, this is not a limitation. The first baffle plate 40 can also be disposed on the outer side of the first side plate 31, and the filter screen 50 can be disposed on the inner surface of the first side plate 31 and cover the first opening 311. Users can make the settings according to their actual needs.
[0027] In one embodiment, the first side plate 31 has opposing first side edges 312 and second side edges 313 adjacent to the first opening 311. The first side edge 312 is provided with a plurality of first holes 3121, and the second side edge 313 is provided with a plurality of second holes 3131. One of the plurality of first holes 3121 and one of the plurality of second holes 3131 are combined with the first baffle plate 40. In one embodiment, the plurality of first holes 3121 and the plurality of second holes 3131 correspond one-to-one, and the plurality of first holes 3121 and the plurality of second holes 3131 are arranged sequentially along the direction of the first height H1. The first baffle plate 40 has a first groove 41 corresponding to the first side edge 312, and the first baffle plate 40 has a second groove 42 corresponding to the second side edge 313. The first groove 41 corresponds to the plurality of first holes 3121, and the second groove 42 corresponds to the plurality of second holes 3131. In other words, a first hole 3121 and a second hole 3131 are horizontally arranged to form a pair of holes. In this embodiment, a total of three pairs of holes are provided on the first side plate 31, but this is not a limitation. The spacing and number of holes can be evenly set according to the size of the opening and the size to be adjusted. The first baffle plate 40 can be fixedly connected to rod-shaped elements (not shown in the figure) at the first slide groove 41 and the second slide groove 42, respectively. The two rod-shaped elements are horizontally arranged, and the shape of the rod-shaped elements matches the shape of the first hole 3121 and the second hole 3131. When the rod-shaped elements are inserted into the first hole 3121 and the second hole 3131, the first baffle plate 40 can be restricted to a position at a certain height from the platform 10 to expose the first opening 311 of a certain size. When it is necessary to adjust the first opening 311, the first baffle plate can be used to fix the first opening 311. When the size of the first opening 311 exposed by the first shield 40 is reached, the rod-shaped element can be removed from the first hole 3121 and the second hole 3131. The first hole 3121 and the second hole 3131 at appropriate heights can be selected, and the rod-shaped element can be inserted into the first hole 3121 and the second hole 3131 at the corresponding heights. This allows for adjustment of the relative position between the first shield 40 and the first side plate 31, thereby adjusting the size of the first opening 311 exposed by the first shield 40 and thus adjusting the amount of air entering the working space of the developing machine body 20.
[0028] In one embodiment, one of the first side plate 31 and the first shielding plate 40 is provided with a groove, and the other of the first side plate 31 and the first shielding plate 40 is provided with a slide rail that cooperates with the aforementioned groove. Thus, by means of the cooperation of the groove and the slide rail, the area covered by the first shielding plate 40 on the first opening 311 can be adjusted to regulate the amount of air entering the working space of the developing machine body 20. In practical applications, the aforementioned groove and slide rail are arranged along the direction of the first height H1, allowing the first shielding plate 40 to move vertically; alternatively, the aforementioned groove and slide rail can also be arranged perpendicular to the direction of the first height H1, allowing the first shielding plate 40 to move horizontally, and this is not a limitation.
[0029] In one embodiment, a first sensor 12 is provided on the stage 10, and a second sensor 37 is provided on the cover 30. The first sensor 12 and the second sensor 37 are arranged opposite to each other. The second sensor 37 is located on the side of the second side plate 32 or the fourth side plate 34 near the first side plate 31 and is a certain distance away from the first through hole 11 of the stage 10. In practical applications, the first sensor 12 and the second sensor 37 are interlocked sensors. The interlocking sensors detect whether the cover 30 is correctly placed on the developing machine body 20, preventing the developing solution from splashing due to gaps caused by improper placement of the cover 30.
[0030] In one embodiment, such as Figure 1 As shown, the first side plate 31 has a first height H1, and the third side plate 33 has a second height H2. The first height H1 is greater than the second height H2, so that the top plate 35 connecting the first side plate 31 and the third side plate 33 is inclined. The second side plate 32 and the fourth side plate 34 are the same trapezoidal structure. The plane where the top plate 35 and the stage 10 are located has a first angle A1. The first angle A1 is between 10° and 45°, so that the cover 30 is an inclined trapezoidal structure. When air enters the working space of the developing machine body 20 through the first opening 311, the airflow path is the inclined direction of the top plate 35. That is to say, the air flows obliquely downward, which can enhance the airflow. In practical applications, the height difference between the first height H1 and the second height H2 can be set as needed to adjust the size of the first angle A1, and it is not limited to this.
[0031] In one embodiment, the top plate 35 is further provided with a first handle 38 and a second handle (not shown in the figure, but horizontally corresponding to the first handle 38). The first handle 38 is located on the side of the top plate 35 adjacent to the second side plate 32, and the second handle is located on the side of the top plate 35 adjacent to the fourth side plate 34. In practical applications, after the developing process is completed, the operator can use the first handle 38 and the second handle to remove the cover 30 to expose the developed display panel below.
[0032] In summary, this utility model provides a developing apparatus, which includes a stage, a developing machine body, a cover, a first baffle plate, and a filter screen. The stage has a first through hole to expose the developing machine body below. The cover is provided on top of the developing machine body. The cover includes a first side plate, a second side plate, a third side plate, and a fourth side plate connected to each other. The first side plate has a first opening. The first baffle plate is movably disposed on the first side plate and is disposed corresponding to the first opening. By adjusting the relative position between the first baffle plate and the first side plate, the size of the first opening exposed by the first baffle plate can be adjusted. Furthermore, a filter screen is disposed corresponding to the first opening of the first side plate. When air enters the working space of the developing machine body through the first opening, it is first filtered and cleaned by the filter screen to prevent developer splashing while ensuring the cleanliness of airflow and improving production yield.
[0033] Of course, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
