Description

Technical Field

[0001] This utility model relates to the technical field of LCD module cleaning equipment, and specifically discloses a cleaning device for LCD module production and processing. Background Technology

[0002] In simple terms, an LCD module is a screen plus a backlight assembly used to display images and text. It consists of one or more LCD screens. The working principle of an LCD module is based on the LCD screen, which is composed of a series of small pixels made up of liquid crystal molecules. Each pixel has an electrode. When a voltage is applied to the electrode, the liquid crystal molecules emit light, thereby displaying images and text. During the production process of LCD modules, cleaning equipment is used to clean the LCD modules and their components to remove dust adhering to the surface of the LCD modules.

[0003] Chinese patent CN213814183U discloses a cleaning device for LCD module production and processing, relating to the field of LCD module production and processing. The device includes a cleaning chamber containing a cleaning mechanism. The cleaning mechanism comprises a ring-shaped drive frame, a disc-shaped support frame, a first lead screw, a second lead screw, a ring-shaped cleaning frame, cleaning brushes, a ring-shaped displacement frame, a disc-shaped displacement frame, and a cleaning housing. This device enables efficient cleaning of LCD module components, has a simple structural design, is easy to operate, and reduces production and processing costs. It allows for mechanized loading and unloading of LCD module components, saving time, improving device efficiency, and reducing manual labor. The cleaning device effectively cleans the outer wall of the housing and avoids clogging of the permeable mesh. However, the cleaning mechanism in the above-mentioned cleaning device is complex, which is not conducive to assembly and maintenance. The above-mentioned cleaning device cannot fix the components in the plate-shaped or frame-shaped liquid crystal module during the cleaning process, which affects the cleaning effect of the liquid crystal module to a certain extent. It is also easy to cause the liquid crystal module to collide and be damaged during the cleaning process, increasing the wear and tear of the liquid crystal module. In addition, the above-mentioned cleaning device does not have the function of draining liquid crystal module, which requires the use of an additional draining device to drain the liquid crystal module after cleaning, which is inconvenient. Therefore, in order to solve the above problems, this utility model proposes a cleaning device for liquid crystal module production and processing. Utility Model Content

[0004] The present invention aims to provide a cleaning device for the production and processing of liquid crystal modules. It has a simple structure, is easy to install and maintain, and can fix various sizes of plate-shaped, frame-shaped and other shaped parts of liquid crystal modules in the placement structure to avoid collision between the parts in the liquid crystal module during the cleaning process, reduce the wear and tear of the liquid crystal module, and has a water-draining function to facilitate the draining of the cleaned liquid crystal module and ensure the cleanliness of the cleaning operation environment.

[0005] This utility model is achieved through the following technical solution:

[0006] A cleaning device for LCD module manufacturing includes an ultrasonic cleaning chamber and a placement structure. The ultrasonic cleaning chamber has multiple placement structures inside. One end of the ultrasonic cleaning chamber has a drain structure. Each placement structure includes a support plate and support legs. Two first support legs are connected to the lower sides of the support plate. Placement racks are provided on the upper sides of the support plate. Multiple placement slots are evenly spaced on one side of each placement rack. A U-shaped stop bar is provided at one end of each placement rack. The drain structure includes a drain plate and a water tank, with the water tank located below the drain plate.

[0007] As a further feature of the above solution, the inner wall of the ultrasonic cleaning box is provided with multiple sliding grooves at equal intervals on both sides. A limit block is provided on one side of the first support leg. The limit block is slidably connected to the sliding groove, which can limit the position of the placement structure and keep the placement structure stable during the cleaning process. Two slots are symmetrically provided on the end of the ultrasonic cleaning box near the drain structure for easy connection with the insertion block. A controller is provided on the end of the ultrasonic cleaning box away from the slots for easy control of the operation of the ultrasonic cleaning box. A placement plate is hinged to one side of the ultrasonic cleaning box. The placement plate can be unfolded from one side of the ultrasonic cleaning box before cleaning the LCD module, providing a working surface for the worker to place the LCD module to be cleaned. It is convenient to place the LCD module to be cleaned on the placement plate in the placement structure. When not in use, one side of the ultrasonic cleaning box can be retracted to save the space occupied by the device.

[0008] As a further feature of the above solution, multiple mounting holes are symmetrically arranged at both ends of the upper part of the support plate, and a first mounting shaft is provided at both ends of the lower part of the mounting bracket. The first mounting shaft passes through the interior of the mounting hole, and a first nut is threaded to the outer side of the first mounting shaft. This helps to adjust the installation position of the mounting bracket according to the size of the plate-shaped or frame-shaped liquid crystal module parts to be cleaned, so that the placement slots on the opposite side of the two mounting brackets match the liquid crystal module parts.

[0009] As a further feature of the above solution, a storage basket is provided above the support plate, and two second mounting shafts are provided on both sides below the storage basket. The second mounting shafts pass through the interior of the mounting holes, and a second nut is threaded onto the outer side of the second mounting shafts. A pressure plate is detachably connected above the storage basket, which facilitates the centralized placement of components of liquid crystal modules of shapes other than plate-shaped and frame-shaped.

[0010] As a further feature of the above solution, a handle is provided on the top of the mounting frame for easy gripping by workers. Both ends of the mounting frame are provided with L-shaped limiting grooves, and both ends of the U-shaped stop bar are provided with L-shaped protrusions. The L-shaped protrusions are slidably connected to the L-shaped limiting grooves, which can confine the plate-shaped or frame-shaped liquid crystal module components in the placement groove, preventing the liquid crystal module components from falling out of the placement structure during the cleaning process.

[0011] As a further feature of the above solution, two inserts are symmetrically arranged on the side of the drain plate near the ultrasonic cleaning box. The inserts slide in the slots to facilitate alignment of the drain structure and the ultrasonic cleaning box. The drain plate is detachably connected to the water tank for easy installation, cleaning, and maintenance of the components. A drain pipe is located on the lower side of the water tank, and a cap is detachably connected to the end of the drain pipe away from the water tank to facilitate the discharge of wastewater collected in the water tank. A handle is located on the upper side of the water tank away from the inserts for easy gripping by workers. Multiple second support legs are connected to the lower part of the water tank, and rollers are connected to the lower part of the second support legs to facilitate adjustment of the position of the drain structure, allowing the drain structure to be used as a placement structure and a transport vehicle for LCD modules, thus enriching the usage of the drain structure.

[0012] The present invention has the following beneficial effects during use:

[0013] The design of multiple sliding grooves on both sides of the inner wall of the ultrasonic cleaning chamber facilitates connection with the limiting block to restrict the position of the placed structure in the ultrasonic cleaning chamber, so that multiple placed structures maintain a certain distance during the cleaning process, ensuring the cleaning effect of the ultrasonic cleaning chamber on the LCD module components.

[0014] The design of multiple mounting holes at both ends of the support plate in the placement structure helps to adjust the installation position of the two opposing mounting brackets according to the size of the plate-shaped or frame-shaped components of the LCD module to be cleaned. This allows the components to be placed in the two opposing placement slots on both sides. The combination of L-shaped limiting slots and U-shaped stops at both ends of the mounting brackets can restrict the position of the LCD module components, preventing them from falling from one end of the placement slot during the cleaning process and ensuring the cleaning effect. The combination of the storage basket and the pressure plate facilitates the centralized placement of LCD module components of shapes other than plate-shaped and frame-shaped, thus expanding the applicability of the placement structure.

[0015] 3. The combination of the drain plate and water tank in the drain structure makes it easy to place the cleaned placement structure and LCD module on the drain plate to drain, so as to ensure the cleanliness of the cleaning operation environment. The design of multiple rollers under the water tank makes it easy to adjust the position of the drain structure, so that the drain structure can be used as a transfer vehicle for the placement structure and LCD module when needed, thus enriching the usage of the drain structure.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-6 This application will be described in detail with reference to the embodiments.

[0026] An embodiment discloses a cleaning device for LCD module production and processing, including an ultrasonic cleaning box 1 and a placement structure 2. The ultrasonic cleaning box 1 has multiple placement structures 2 inside. One end of the ultrasonic cleaning box 1 is provided with a drain structure 3. The placement structure 2 includes a support plate 21 and support legs. Two first support legs 22 are connected to the lower two sides of the support plate 21. The upper two sides of the support plate 21 are provided with mounting frames 23. Multiple placement slots 233 are equally spaced on one side of the mounting frame 23. One end of the mounting frame 23 is provided with a U-shaped baffle 24. The drain structure 3 includes a drain plate 31 and a water tank 32. The water tank 32 is provided below the drain plate 31.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the inner wall of the ultrasonic cleaning box 1 is provided with multiple sliding grooves 11 at equal intervals on both sides. A limit block 221 is provided on one side of the first support leg 22. The limit block 221 is slidably connected to the sliding groove 11, which can limit the position of the placement structure 2 and keep the placement structure 2 stable during the cleaning process. Two slots 12 are symmetrically provided at the end of the ultrasonic cleaning box 1 near the drain structure 3 for easy connection with the plug 311. A controller 13 is provided at the end of the ultrasonic cleaning box 1 away from the slots 12 for easy control of the operation of the ultrasonic cleaning box 1. A placement plate 14 is hinged to one side of the ultrasonic cleaning box 1. The placement plate 14 can be unfolded from one side of the ultrasonic cleaning box 1 before cleaning the liquid crystal module, providing a working surface for the worker to place the liquid crystal module to be cleaned. It is convenient to place the liquid crystal module to be cleaned on the placement plate 14 into the placement structure 2. When not in use, one side of the ultrasonic cleaning box 1 can be retracted to save the space occupied by the device.

[0028] like Figure 3 , Figure 4 and Figure 5 As shown, the support plate 21 has multiple mounting holes 211 symmetrically arranged at both ends of its upper part, and the mounting bracket 23 has a first mounting shaft 231 arranged at both ends of its lower part. The first mounting shaft 231 passes through the interior of the mounting hole 211, and a first nut 232 is threaded to the outer side of the first mounting shaft 231. This helps to adjust the installation position of the mounting bracket 23 according to the size of the plate-shaped or frame-shaped liquid crystal module parts to be cleaned, so that the placement slots 233 on the opposite side of the two mounting brackets match the liquid crystal module parts.

[0029] like Figure 5 As shown, a storage basket 25 is provided above the support plate 21. Two second mounting shafts 251 are provided on both sides of the lower part of the storage basket 25. The second mounting shafts 251 pass through the interior of the mounting hole 211. A second nut 252 is threaded to the outer side of the second mounting shaft 251. A pressure plate 253 is detachably connected to the upper part of the storage basket 25, which facilitates the centralized placement of components of liquid crystal modules of other shapes besides plate-shaped and frame-shaped.

[0030] like Figure 3 and Figure 4 As shown, a handle 234 is provided on the top of the mounting frame 23 for easy gripping by workers. Both ends of the mounting frame 23 are provided with L-shaped limiting grooves 235, and both ends of the U-shaped stop bar 24 are provided with L-shaped protrusions 241. The L-shaped protrusions 241 are slidably connected to the L-shaped limiting grooves 235, which can restrict the plate-shaped or frame-shaped liquid crystal module components in the placement groove 233 and prevent the liquid crystal module components from falling out of the placement structure 2 during the cleaning process.

[0031] like Figure 1 and Figure 6 As shown, two inserts 311 are symmetrically arranged on the side of the drain plate 31 near the ultrasonic cleaning box 1. The inserts 311 slide with the slots 12 to facilitate the alignment of the drain structure 3 and the ultrasonic cleaning box 1. The drain plate 31 is detachably connected to the water tank 32 to facilitate the installation, cleaning and maintenance of the above components. A drain pipe 321 is provided on the lower side of one side of the water tank 32. A cover 322 is detachably connected to the end of the drain pipe 321 away from the water tank 32 to facilitate the discharge of sewage collected in the water tank 32. A handle 33 is provided on the upper side of the water tank 32 away from the inserts 311 for easy gripping by workers. Multiple second support legs 34 are connected to the lower part of the water tank 32. Rollers 35 are connected to the lower part of the second support legs 34 to facilitate the adjustment of the position of the drain structure 3, so that the drain structure 3 can be used as a transfer cart for placing the structure 2 and the LCD module, thus enriching the usage of the drain structure 3.

[0032] The cleaning apparatus for manufacturing and processing liquid crystal modules disclosed in this embodiment involves injecting sufficient clean water into the ultrasonic cleaning chamber 1 before cleaning, adding appropriate cleaning agent to the clean water according to cleaning requirements, unfolding the placement plate 14 from one side of the ultrasonic cleaning chamber 1, placing the placement structure 2 on the placement plate 14, adjusting the mounting hole 211 through which the first mounting shaft 231 at the lower end of the mounting bracket 23 passes according to the size of the plate-shaped or frame-shaped components of the liquid crystal module to be cleaned, and fixing it with the first nut 232, and sequentially placing multiple plate-shaped or frame-shaped liquid crystal module components to be cleaned from the open end of the placement groove 233 into two opposite placement grooves 233, so that one end of the component abuts against the surface of the placement groove 233. Place the closed end of the placement slot 233. After placement, connect the L-shaped protrusions 241 at both ends of the U-shaped stop bar 24 to the two L-shaped limiting slots 235 respectively. Adjust the position of the U-shaped stop bar 24 so that the L-shaped protrusions 241 slide in the L-shaped limiting slots 235 until the U-shaped stop bar 24 and the part are on opposite sides and come into contact with each other. Place the other U-shaped stop bar 24 in the same way. Remove the pressure plate 253 at the top of the storage basket 25. Place other small-sized or other shapes of LCD module parts, except for larger plate-shaped and frame-shaped parts, into the storage basket 25 and then reset the pressure plate 253. This prevents the parts from floating around in the ultrasonic cleaning box 1 during the cleaning process and saves time when removing the parts.

[0033] After placement, use both hands to pull the handles 234 at both ends of the two mounting brackets 23 to transfer the placement structure 2 containing the LCD module components from the shelf 14 to the ultrasonic cleaning chamber 1. Align the limiting block 221 with the slide 11 and slide it from the top of the slide 11 to the bottom of the slide 11. At this time, the lower end of the first support leg 22 is in contact with the bottom of the ultrasonic cleaning chamber 1. Use the controller 13 to start the ultrasonic cleaning chamber 1 to clean the LCD module. After cleaning, use both hands to pull the two handles 234 in the same placement structure 2 to pull the placement structure 2 together with the LCD module out of the ultrasonic cleaning chamber 1 and place it on the drain plate 31 for draining. Wastewater dripping from the components falls into the water tank 32 through the drain plate 31. After the draining is complete, the LCD module is cleaned. At this time, hold the handle 33 and pull the insert 311 out of the slot 12. The drain structure 3, together with the placement structure 2 and the LCD module, can be transported to a suitable position. This can effectively prevent wastewater from dripping onto the ground during the transportation process. When the wastewater in the water tank 32 reaches a sufficient amount, unscrew the cover 322 from one end of the drain pipe 321 to drain the wastewater from the water tank 32. Alternatively, the cover 322 can be unscrewed before cleaning the LCD module, and the original water pipe can be connected to the drain pipe 321 so that the wastewater collected in the water tank 32 can be directly discharged from the water tank 32 through the drain pipe.

[0034] The ultrasonic cleaning box 1, controller 13, shelf 14, first support leg 22, limit block 221, mounting frame 23, first mounting shaft 231, first nut 232, placement groove 233, handle 234, storage basket 25, second mounting shaft 251, second nut 252, pressure plate 253, drain plate 31, insert block 311, water tank 32, drain pipe 321, cover 322, handle 33, second support leg 34, and roller 35 disclosed in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
