Description

Technical Field

[0001] The utility model relates to the technical field of glass container cleaning, in particular to a small glass container cleaning device. Background Art

[0002] Photoresist is one of the key materials for fine pattern processing in microelectronics technology. Small glass containers can be used to store and protect photoresist. It is usually made of glass, has high transparency and chemical corrosion resistance, and can prevent photoresist from contacting the external environment and causing quality deterioration.

[0003] Announcement No. CN210936328U proposes a cleaning device for a small glass container for photoresist. The cleaning device for a small glass container for photoresist pushes the first clamping plate by a pushing cylinder, and the first clamping plate and the second clamping plate are used to facilitate clamping the glass container. The glass container is cleaned by a pump body, and the glass container is driven to rotate by a motor to clean the glass container in all directions. The drainage pipe is raised to facilitate water recovery.

[0004] When cleaning a small glass container of photoresist, the above patent places the small glass container of photoresist between the first rotating member and the second rotating member, and cooperates with the nozzle to spray water to achieve flushing of the small glass container. The cleaning effect of the small glass container of photoresist is not good only by flushing with water. There will still be residual photoresist on the inner wall of the small glass container, and the cleaning effect is not good. Therefore, we propose a small glass container cleaning device.

It is usually made of glass material, has the characteristics of high transparency and chemical corrosion resistance, and can prevent the photoresist from contacting the external environment and causing quality deterioration. After the small glass container is used, it needs to be cleaned by a cleaning device. However, the existing small glass container cleaning devices are mostly used for flushing when in use, and cannot fully clean the inner wall of the small glass container. There will still be residual photoresist on the inner wall of the small glass container, and the cleaning effect is not good; it comprises a cleaning box 1, the front end surface of the cleaning box 1 is connected to a box door 2, and the bottom of the cleaning box 1 is provided with a storage device connected thereto. A rotating assembly is provided at the bottom of the inner cavity of the water tank 3 and the cleaning box 1, and the rotating assembly includes a rotating toothed disc 11, side panels 12 are installed on both sides of the upper surface of the rotating toothed disc 11, and the side panels 12 are internally threadedly connected with an adjusting screw 16, and an arc-shaped clamping plate 17 is provided at the bottom of the adjusting screw 16, and a slidingly connected cleaning column 13 is provided in the inner cavity of the cleaning box 1, and a plurality of groups of cleaning brushes 15 and a nozzle 14 are provided on the outer wall of the cleaning column 13, and the cleaning column 13 is connected to the water storage tank 3 through a water supply unit, and a drain pipe 18 is connected to the bottom of the right side of the cleaning box 1, and a filter element is provided in the inner cavity of the drain pipe 18 to facilitate the filtering and discharge of sewage, and drying units 19 are symmetrically provided on both sides of the inner wall of the cleaning box 1, and the drying unit 19 is an electric heating component with a waterproof structure, which is dried after cleaning.

[0021] The box door 2 is movably connected to the cleaning box 1 through hinges, and a porthole is installed on the box door 2 to facilitate viewing the cleaning effect of the small glass container inside. The box door 2 is also installed with a controller, which controls the operation of each electrical device, and the electrical end of each electrical device is electrically connected to the electrical end of the external power supply; when cleaning the small glass container of photoresist, the box door 2 is opened, the sliding cleaning column 13 moves up, and then the small glass container is placed on the upper surface of the rotating gear disk 11, and then the adjusting screws 16 in the two sets of side plates 12 are rotated (the bottom of the adjusting screw 16 is connected to the outer wall of the arc clamping plate 17 through the bearing), which drives the two sets of arc clamping plates 17 to move in relative directions, so as to realize the position of the small glass container of photoresist to be cleaned. The cleaning column 13 is fixed, and then the cleaning column 13 is moved downward so that the cleaning column 13 is located in the inner cavity of the small glass container. Then, the box door 2 is closed, and the rotating component and the water supply unit are started. The water supply unit transports the water in the water storage tank 3 to the multiple groups of nozzles 14 on the cleaning column 13. The nozzles 14 spray water. The rotating component works to rotate the rotating gear disk 11. The nozzles 14 spray water to cooperate with the rotation of the small glass container on the rotating gear disk 11, thereby achieving all-round cleaning of the inner wall of the photoresist small glass container, with better cleaning effect. The sewage after cleaning is discharged into the water storage tank 3 through a water pipe and can be reused (the cleaning box 1 is connected to the water storage tank 3 through a water pipe, and a connected water supply pipe and a drain pipe are provided on the water storage tank 3 to facilitate water supply and drainage).

[0022] Among them, preferably, the rotating assembly also includes a stepper motor 9, the stepper motor 9 is located on the left outer wall of the cleaning box 1, and the output end of the stepper motor 9 is connected to a driving gear 10, the bottom end of the left outer wall of the cleaning box 1 is provided with an opening adapted to the driving gear 10, and the driving gear 10 is meshed and connected with a rotating toothed disc 11, and the middle part of the lower surface of the rotating toothed disc 11 is rotatably connected to the bottom wall of the inner cavity of the cleaning box 1 through a bearing;

When placing a small glass container, the cleaning column 13 will not block the small glass container. After determining the position of the cleaning column 13, the threaded locking nut 8 is rotated to make it fit on the upper surface of the fixing plate 5, thereby completing the fixation of the position of the lifting screw 6, that is, the position of the cleaning column 13 is fixed.
