Description

Technical Field

[0001] This application relates to the technical field of display module cleaning, and in particular to an automatic cleaning production apparatus and method for display modules. Background Technology

[0002] During the production of display modules, the glass that makes up the display modules needs to be cut into the required size. The debris and oil stains generated during cutting may adhere to the glass surface. Therefore, glass cleaning is an indispensable step. Its purpose is to remove debris and oil stains from the glass surface, thereby ensuring the stability of the glass performance in subsequent processes.

[0003] For example, patent application CN211563808U discloses a glass display module cleaning device, including a base and a loading rack on it. The top of the loading rack has a support that can be rotated by a servo motor, and the bottom of the mounting mold on the support has a receiving groove with a vacuum suction cup to fix the module. The gantry frame on the base is driven by a first driving component, and its slider is driven by a second driving component to slide horizontally. The cleaning disc on the slider has multiple nozzles for spraying cleaning fluid. Because the other surfaces of the module are covered by the mounting mold, and the spraying method is from bottom to top, the cleaning fluid does not easily penetrate to other surfaces, improving the cleaning quality.

[0004] However, when using the above-mentioned technology to clean display modules, specifically their surface glass, there are still some shortcomings that need to be addressed: On the one hand, given that the glass of the display module itself has extremely high precision requirements, its physical properties determine that it is quite sensitive to external forces. However, in the existing cleaning process, the water jet will carry a certain pressure. When this pressure acts on the high-precision glass surface, it is very easy to exceed the maximum pressure that the glass can withstand, which will cause damage such as cracks, chipping, or even breakage of the glass, directly affecting the product yield.

[0005] On the other hand, a layer of oil film that is difficult to remove often adheres to the glass surface. This oil film has a certain degree of hydrophobicity, which prevents the sprayed water from spreading smoothly on the glass surface and making it difficult to fully contact the oil film area and produce an effective cleaning effect. As a result, the oil film cannot be completely removed, which ultimately leads to a significant reduction in the cleaning effect of the glass and fails to meet the strict standards for the cleanliness of the glass surface in subsequent production and processing. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this application provides an automatic cleaning production device and method for display modules, adopting the following technical solution:

[0007] In a first aspect, this application proposes an automatic cleaning production apparatus for display modules, including a U-shaped frame. A fixing mechanism for limiting and fixing the glass is installed in the middle of the U-shaped frame. A cleaning mechanism for cleaning the glass surface is also installed inside the U-shaped frame, including:

[0008] The jet pipe, located inside the spiral frame, sprays air onto the glass surface.

[0009] The movable frame extends along the width of the loop and is set inside the loop. Multiple cleaning racks are evenly installed on the movable frame along its length, and the air jet pipe and the cleaning rack are located on both sides of the fixed mechanism along the length of the loop.

[0010] The cleaning rack has a connecting protrusion on the top side near the air jet pipe, and a water spray pipe is installed on the connecting protrusion.

[0011] The swing frame, installed on the cleaning rack, is used to swing the water sprayed from the water pipe. Guide rods are symmetrically arranged on the swing frame along the length of the moving frame.

[0012] Preferably, the fixing mechanism includes a rotating shaft disposed inside the loop frame and extending along its height direction. The two ends of the rotating shaft are rotatably mounted on the inner wall of the loop frame via bearings. A fixing frame is mounted on the rotating shaft via a resetting telescopic plate. Multiple vacuum suction cups are evenly arranged on the side of the fixing frame away from the telescopic plate.

[0013] Preferably, the bottom of the loop frame is slidably provided with movable blocks that are symmetrically distributed along its length and cooperate with the cleaning mechanism. The movable block that cooperates with the air jet pipe is set as movable slider one, and the movable block that cooperates with the movable frame is set as movable slider two. A lifting cylinder is mounted on movable slider one through a cylinder seat. A lifting plate is mounted on the telescopic end of the lifting cylinder, and the air jet pipe is set on the side wall of the lifting plate near the rotating shaft.

[0014] Preferably, elastic telescopic rods are symmetrically installed at the top of the U-shaped frame along its width direction, and a linkage plate is installed at the telescopic ends of the elastic telescopic rods. A sponge for wiping the glass surface is installed at the bottom of the linkage plate, and a linkage frame that cooperates with the linkage plate is installed on the lifting plate.

[0015] Preferably, the bottom of the U-shaped frame is symmetrically provided with fixed protrusions that cooperate with the moving blocks along its length. A telescopic spring rod is installed between the fixed protrusions and the moving blocks on the corresponding sides. The bottom end of the rotating shaft passes through the bottom of the U-shaped frame. A winding wheel is installed on the bottom circumference of the rotating shaft. A pull rope is provided between the winding wheel and the moving blocks on the corresponding sides. One end of the pull rope is installed on the moving block on the corresponding side, and the other end of the pull rope is wound around the winding wheel.

[0016] Preferably, the top end of the rotating shaft extends through the top of the loop frame, and a drive motor is mounted on the top of the loop frame via a motor mount. The output shaft of the drive motor is connected to the rotating shaft via a transmission connection, and an isolation plate is installed on the part of the rotating shaft located inside the loop frame.

[0017] Preferably, an arc-shaped frame is installed on the side wall of the lifting plate near the rotating shaft, the jet pipe is rotatably installed inside the arc-shaped frame, a gear is installed on the jet pipe, a support plate is installed on the moving slider, and an incomplete rack plate that cooperates with the gear is installed on the support plate.

[0018] Preferably, a reciprocating frame is mounted on the movable slider two, an electric slider is mounted on the reciprocating frame, and the movable frame is mounted on the electric slider through a connecting plate. A swing shaft is rotatably mounted on the cleaning frame through a bearing, and a sprocket is mounted on the swing shaft.

[0019] Preferably, the cleaning rack is equipped with a guide plate for guiding wastewater from cleaning the glass, and multiple guide grooves are evenly provided on the cleaning rack along the length of the movable frame for guiding wastewater on the guide plate. A drain trough for discharging wastewater is provided at the bottom of the U-shaped frame.

[0020] Secondly, this application also proposes an automatic cleaning production method for display modules, using the aforementioned apparatus, specifically including the following steps:

[0021] S1: Placement preparation. Place the glass on the side of the mounting bracket and use a vacuum suction cup to fix the glass to the mounting bracket.

[0022] S2: Cleaning process, using a jet nozzle to spray air onto the glass surface, causing impurities on the glass surface to fall off under the action of the airflow.

[0023] S3: Cleaning process. Rotate the glass so that the cleaned glass faces the cleaning rack and is cleaned in conjunction with the water flow.

[0024] S4: Drying process. Rotate the glass back to the starting position and dry the cleaned glass.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] Once the water enters the device, the guide rod initially regulates the water flow direction, while the swing frame, utilizing its dynamic oscillation characteristics, further disperses and divides the water flow, ultimately allowing it to cover the glass surface in a more even manner. This design effectively solves the problem of water pooling and insufficient contact caused by the presence of an oil film on the glass surface during traditional cleaning processes. It also reduces the problem of water flow not spreading smoothly and leaving cleaning dead zones due to the hydrophobicity of the oil film. The uniform water flow after being guided can overcome the barrier of the oil film, ensuring that the glass surface can fully contact the water flow, thus improving the cleaning effect of the glass from the root.

[0027] Furthermore, the continuous oscillation of the swing frame significantly increases the contact area between the water flow and the glass. The dynamic coverage range formed by its oscillation trajectory makes the washing process more thorough, ensuring that even the fine lines or dents on the glass surface are fully moistened by the water flow.

[0028] Furthermore, the swing arm creates a slight contact force with the glass surface during its swing. Driven by the water flow, this creates a wiping-like effect. That is, as the water flows over the glass surface, the swing arm moves synchronously with the direction of the water flow, thoroughly removing residual impurities (such as fine dust particles and dried water stains) that are difficult to remove by the impact of water alone. This achieves a dual cleaning effect of rinsing and wiping, significantly improving the cleanliness and thoroughness of glass cleaning.

[0029] The jet pipe designed in this invention can perform all-round, no-dead-angle jet treatment on the glass surface when it moves up and down vertically inside the loop frame, gradually covering the glass from bottom to top, ensuring that every area is effectively affected by the airflow.

[0030] For stubborn impurities adhering to glass surfaces, such as long-accumulated dust and dried stains, water alone is often insufficient for complete removal. However, the airflow from the jet nozzle directly targets these stubborn impurities, using the thrust generated by the airflow to break the adhesion between the impurities and the glass surface, blowing them away. This jet-assisted treatment method is highly targeted and can quickly and effectively remove impurities that are difficult to break down by water.

[0031] More importantly, this function of the air jet can greatly reduce the reliance on the contact force between the swing frame and the glass during the cleaning process. In other words, the air jet treatment of the air jet effectively removes stubborn impurities in advance, so that the swing frame no longer needs to bear excessive contact force. It only needs to maintain the original slight contact force to complete the subsequent cleaning work, which not only ensures the cleaning effect, but also further protects the integrity of the glass.

[0044] The following is in conjunction with the appendix Figures 1 to 11 This application will be described in further detail.

[0045] This application discloses an automatic cleaning production apparatus and method for display modules, which can pre-treat impurities on the glass before cleaning, and then use a uniform water flow to ensure that the water flow is in complete contact with the glass surface, reducing the possibility of the glass oil film blocking the water flow and ensuring the cleaning effect of the glass surface.

[0046] Example 1

[0047] The automatic cleaning production device for display modules includes a U-shaped frame 1, a fixing mechanism 2 for limiting and fixing the glass is installed in the middle of the U-shaped frame 1, and a cleaning mechanism 3 for cleaning the glass surface is also installed inside the U-shaped frame 1.

[0048] The jet pipe 31 is located inside the spiral frame 1 and jets air onto the glass surface.

[0049] The movable frame 32 extends along the width direction of the loop frame 1 and is set inside the loop frame 1. Multiple cleaning racks 33 are evenly installed on the movable frame 32 along its length direction, and the jet pipe 31 and the cleaning racks 33 are located on both sides of the fixing mechanism 2 along the length direction of the loop frame 1.

[0050] A connecting protrusion is provided on the top side of the cleaning rack 33 near the jet pipe 31, and a water spray pipe 34 is installed on the connecting protrusion.

[0051] The swing frame 35 is set on the cleaning frame 33 and is used to swing the water sprayed by the water pipe 34. Guide rods 36 are symmetrically arranged on the swing frame 35 along the length of the moving frame 32.

[0052] When the jet pipe 31 moves up and down vertically inside the U-shaped frame 1, it can perform all-round, no-dead-angle jet treatment on the glass surface, gradually covering the glass from bottom to top, ensuring that every area is effectively affected by the airflow, thereby removing stubborn impurities on the glass.

[0053] The swing frame 35 is made of rubber. After the glass surface is cleaned with airflow, the glass is rotated so that the cleaned surface is aligned with the swing frame 35. Water then enters between the glass and the swing frame 35 through the spray pipe 34. The guide rod 36 initially regulates the water flow direction, while the swing frame 35, with its dynamic swinging characteristics, further disperses and divides the water flow, ultimately ensuring a more even water coverage on the glass surface. This avoids the problems of water pooling and insufficient contact caused by the presence of an oil film on the glass surface during traditional cleaning processes, and reduces the problem of water not spreading smoothly due to the hydrophobicity of the oil film, leaving cleaning dead spots.

[0054] In the initial state, the glass needs to be fixed. The fixing mechanism 2 provided by the present invention can fix and limit the glass. Specifically, the fixing mechanism 2 includes a rotating shaft 21 set inside the loop frame 1 and extending along its height direction. The two ends of the rotating shaft 21 are rotatably mounted on the inner wall of the loop frame 1 through bearings. A fixing frame 22 is installed on the rotating shaft 21 through a resetting telescopic plate. Multiple vacuum suction cups 23 are evenly arranged on the side of the fixing frame 22 away from the telescopic plate.

[0055] The bottom of the loop frame 1 is slidably provided with movable blocks 11 that are symmetrically distributed along its length and cooperate with the cleaning mechanism 3. The movable block 11 that cooperates with the jet pipe 31 is set as movable slider one 111, and the movable block 11 that cooperates with the movable frame 32 is set as movable slider two 112. A lifting cylinder 12 is mounted on the movable slider one 111 through a cylinder seat. A lifting plate 13 is mounted on the extension end of the lifting cylinder 12, and the jet pipe 31 is set on the side wall of the lifting plate 13 near the rotating shaft 21.

[0056] The bottom of the loop frame 1 has a through groove that cooperates with the first movable slider 111 and the second movable slider 112. In the initial position, the first movable slider 111 and the second movable slider 112 are located on the side of the through groove close to the rotating shaft 21. In actual operation, the existing robot gripper (which is existing technology and is not shown) grabs the glass, so that the glass is vertically inserted between the fixed frame 22 and the jet pipe 31, and the glass is attached to the vacuum suction cup 23. The vacuum suction cup 23 can adsorb and fix the glass on the fixed frame 22. At this time, the fixed frame 22 and the vacuum suction cup 23 cooperate with each other to fix and limit the glass.

[0057] In the initial position, the extension end of the lifting cylinder 12 is in a fully retracted state. Then, the jet pipe 31 is connected to the outlet of the existing air pump (the air pump is existing technology and will not be described in detail). Multiple jet holes are evenly opened along the length of the side of the jet pipe 31 near the fixing frame 22. After the glass is fixed and limited, the lifting cylinder 12 is activated. During the upward movement of the extension end of the lifting cylinder 12, the jet pipe 31 is moved upward synchronously. During the movement of the jet pipe 31, the existing air pump is activated to fill the jet pipe 31 with gas. The gas inside the jet pipe 31 is sprayed onto the glass through the jet holes, and the airflow can clean the impurities on the glass.

[0058] For stubborn impurities adhering to glass surfaces, such as long-accumulated dust and dried stains, water alone is often insufficient for complete removal. However, the airflow from the jet pipe 31 directly targets these stubborn impurities, using the thrust generated by the airflow to break the adhesion between the impurities and the glass surface, blowing them away. This jet-assisted treatment method is highly targeted and can quickly and effectively remove impurities that are difficult to break down by water.

[0059] More importantly, this function of the jet pipe 31 can greatly reduce the dependence on the contact force between the swing frame 35 and the glass during the cleaning process. In other words, the jet treatment of the jet pipe 31 effectively removes stubborn impurities in advance, so that the swing frame 35 no longer needs to bear excessive contact force. It only needs to maintain the original slight contact force to complete the subsequent cleaning work, which not only ensures the cleaning effect, but also further protects the integrity of the glass.

[0060] The telescopic plate adopts a common elastic telescopic structure. During the process of jetting airflow from the jet pipe 31, the telescopic plate can buffer and absorb the impact force of the airflow on the glass, thereby avoiding damage to the glass due to excessive airflow impact force.

[0061] After the impurities on the glass surface are blown away, the glass needs to be reversed. The rotating shaft 21 provided by the present invention can solve the above problem. The bottom of the U-shaped frame 1 is symmetrically provided with fixed protrusions that cooperate with the moving block 11 along its length direction. A telescopic spring rod 14 is installed between the fixed protrusion and the moving block 11 on the corresponding side. The bottom end of the rotating shaft 21 passes through the bottom of the U-shaped frame 1. A winding wheel 15 is installed on the bottom circumference of the rotating shaft 21. A pull rope 16 is provided between the winding wheel 15 and the moving block 11 on the corresponding side. One end of the pull rope 16 is installed on the moving block 11 on the corresponding side, and the other end of the pull rope 16 is wound around the winding wheel 15.

[0062] The top end of the rotating shaft 21 extends through the top of the loop frame 1. A drive motor 17 is mounted on the top of the loop frame 1 via a motor mount. The output shaft of the drive motor 17 is connected to the rotating shaft 21. An isolation plate 211 is installed on the part of the rotating shaft 21 located inside the loop frame 1.

[0063] At the starting position, the pull rope 16 is in the coiled state, and the telescopic spring rod 14 is in the stretched state. In actual operation, when it is necessary to rinse the glass surface, the drive motor 17 is started. During the rotation of the output shaft of the drive motor 17, the rotating shaft 21 is driven to rotate. During the rotation of the rotating shaft 21, the fixed frame 22 is driven to rotate around the rotating shaft 21 through the telescopic plate. During the rotation of the fixed frame 22, it cooperates with the vacuum suction cup 23 to drive the glass to rotate and change direction.

[0064] During the glass reversal process, the rotating shaft 21 rotates, driving the winding wheel 15 to rotate. During the rotation of the winding wheel 15, the pull rope 16 is released. At this time, the moving block 11 is synchronously reset under the action of the telescopic spring rod 14 on the corresponding side. When the glass rotates to be parallel to the length direction of the loop frame 1, the winding wheel 15 completely releases the pull rope 16, that is, the moving block 11 moves to the maximum position away from the rotating shaft 21. At this time, the rotating shaft 21 continues to rotate and drives the pull rope 16 to wind in the opposite direction. At this time, the telescopic spring rod 14 is in a stretched state. The glass rotates synchronously during the rotation of the rotating shaft 21 until it is parallel to the swing frame 35 and makes slight contact. The isolation plate 211 can separate the cleaning of the glass surface from the cleaning process, avoiding the intermingling of impurities during the two cleaning processes and improving the cleaning effect of the glass.

[0065] During the process of the telescopic spring rod 14 driving the moving block 11 to complete the reset, its movement speed is much greater than the rotation speed of the rotating shaft 21. This speed difference in the design plays a key role: when the glass enters the reversing stage, the moving block 11 can reach its position first with a faster reset speed, leaving sufficient safety space for the glass's turning action, thereby effectively avoiding the risk of the glass colliding with the air jet pipe 31 and the swing frame 35 during the reversing process.

[0066] A reciprocating frame 321 is installed on the movable slider 112, and an electric slider 322 is installed on the reciprocating frame 321. The movable frame 32 is installed on the electric slider 322 through a connecting plate. A swing shaft 323 is rotatably installed on the cleaning frame 33 through a bearing, and a sprocket 324 is installed on the swing shaft 323.

[0067] The cleaning rack 33 is equipped with a guide plate 351 for guiding the wastewater from cleaning the glass. Multiple guide grooves 352 are evenly provided on the cleaning rack 33 along the length of the movable frame 32 for guiding the wastewater on the guide plate 351. A drain trough 353 for discharging wastewater is provided at the bottom of the U-shaped frame 1.

[0068] The water spray pipe 34 is equipped with a guide plate to guide the water inside the water spray pipe 34 to the glass surface. Before the device is put into operation, the position of the swing frame 35 is adjusted multiple times to ensure that when the glass rotates to the side of the swing frame 35, the swing frame 35 just makes slight contact with the glass. This ensures that the swing frame 35 can gently wipe the glass during cleaning, and also avoids the glass surface from being squeezed or scratched due to excessive contact with the swing frame 35.

[0069] In actual operation, before the device starts working, all sprockets 324 are connected by a chain, and the water spray pipe 34 is connected to the outlet of an external water pump (the external water pump is common knowledge and will not be described in detail). When the glass moves to one side of the swing frame 35, water is pumped into the water spray pipe 34 by the external water pump. The water inside the water spray pipe 34 flows to the side of the glass to be cleaned through the guide plate. At this time, the electric slider 322 is started. During the reciprocating movement of the electric slider 322 on the reciprocating frame 321, it drives the cleaning frame 33 to reciprocate through the cooperation of the connecting plate and the moving frame 32. During the reciprocating movement of the cleaning frame 33, the swing frame 35 is driven to wipe the glass surface.

[0070] At this time, the existing motor (not shown in the figure) is started synchronously to drive any one swing shaft 323 to reciprocate. During the reciprocating rotation of the swing shaft 323, it is connected to the chain drive through the sprocket 324 to drive the remaining swing shaft 323 to reciprocate. During the swinging process of the swing shaft 323, it drives the swing frame 35 to reciprocate.

[0071] The uniform water flow guided by the guide rod 36 can break through the barrier of the oil film, ensuring that the glass surface can fully contact the water flow, thus improving the cleaning effect of the glass from the source.

[0072] During the swinging process, the swing frame 35 can also expand the water flow guided by the guide rod 36, significantly increasing the contact area between the water flow and the glass. The dynamic coverage range formed by its swing trajectory makes the water washing process more thorough, and even the fine textures or dents on the glass surface can be fully wetted by the water flow.

[0073] Furthermore, the swing arm 35 creates a slight contact force with the glass surface during its swing. Driven by the water flow, this creates a wiping-like effect. That is, when the water flows over the glass surface, the swing arm 35 spreads the water flow, thoroughly removing residual impurities (such as fine dust particles and dried water stains) that are difficult to remove by the water flow alone. This achieves a dual cleaning effect of rinsing and wiping, significantly improving the cleanliness and thoroughness of glass cleaning.

[0074] Furthermore, when the cleaning rack 33 performs a stable reciprocating translational motion on the horizontal reference plane, it forms a precise synergy with the periodic reciprocating oscillation of the swing rack 35 in the vertical direction. The organic combination of these two motion states can apply alternating forces to the glass surface from both horizontal and vertical dimensions. That is, the horizontal reciprocating motion brings a pushing and pulling force along the glass plane, while the vertical oscillation imparts a pressing and lifting force perpendicular to the glass surface. The two superimpose and dynamically switch, making the external force on the glass exhibit complex and continuously changing characteristics, thereby acting more effectively on the glass surface and improving the cleaning effect of the glass surface.

[0075] In addition, the water flow can form a lubricant between the swing frame 35 and the glass, effectively protecting the glass surface and preventing the swing frame 35 from scratching the glass.

[0076] The wastewater generated during cleaning flows through the guide plate 351 to the guide trough 352 and then into the drain trough 353.

[0077] Elastic telescopic rods 4 are symmetrically installed at the top of the inner frame 1 along its width direction. The telescopic ends of the elastic telescopic rods 4 are connected to a linkage plate 41. A sponge 42 for wiping the glass surface is installed at the bottom of the linkage plate 41. A linkage frame 43 that cooperates with the linkage plate 41 is installed on the lifting plate 13.

[0078] The linkage frame 43 is an inverted L-shaped structure, and the vertical section of the linkage frame 43 is installed on the lifting plate 13. In specific operation, after the glass cleaning is completed, the drive motor 17 is started to reverse its output shaft and drive the glass to reset. During the reversal of the output shaft, the pull rope 16 is released by the winding wheel 15 and then rewinds in the opposite direction. When the glass is reset, the moving block 11 is simultaneously reset to the starting position. Then the lifting cylinder 12 is started to raise the lifting plate 13 to the vicinity of the linkage plate 41. Then the drive motor 17 is started to drive the rotating shaft 21 to rotate a small angle displacement. During the rotation of the rotating shaft 21, the winding wheel 15 is driven to wind the pull rope 16 to a certain length, thereby driving the moving slider 111 to move to one side of the rotating shaft 21 until the horizontal section of the linkage frame 43 moves above the linkage plate 41.

[0079] At this time, the lifting cylinder 12 is activated to drive the lifting plate 13 to move down. During the downward movement of the lifting plate 13, the jet pipe 31 blows water stains on the glass surface, causing the water stains on the glass to move downward and eventually fall off the glass surface. During this process, the horizontal section of the linkage frame 43 drives the linkage plate 41 to move down. During the downward movement of the linkage plate 41, the sponge 42 can wipe the water stains on the glass surface. At this time, the elastic telescopic rod 4 is stretched. Under the dual action of airflow blowing and sponge 42 wiping, the water stains on the glass surface are efficiently cleaned. That is, the airflow can quickly remove most of the fluid water stains, and the sponge 42 can wipe away the residual trace water film. The two work together to avoid the possibility of water stains forming marks after naturally drying on the glass surface, thus ensuring the cleanliness of the glass surface.

[0080] Sponge 42 is replaced regularly to prevent impurities attached to it from re-contaminating the glass.

[0081] Repeat the above steps to clean the other side of the glass.

[0082] Example 2

[0083] Based on Embodiment 1, in order to ensure the cleaning effect of the glass surface, the jet pipe 31 provided by the present invention can also swing back and forth. Specifically, an arc frame 131 is installed on the side wall of the lifting plate 13 near the rotating shaft 21, the jet pipe 31 is rotatably installed inside the arc frame 131, a gear 132 is installed on the jet pipe 31, a support plate 133 is installed on the moving slider 111, and an incomplete rack plate 134 that cooperates with the gear 132 is installed on the support plate 133.

[0084] A hinged spring is installed between the jet pipe 31 and the arc frame 131, which is common knowledge and therefore not shown in the figure or described in detail. In operation, when the lifting plate 13 moves up and down in the vertical direction, it forms a stable transmission connection with the arc frame 131, thereby driving the jet pipe 31 to move synchronously. As the jet pipe 31 moves with the lifting plate 13, the gear 132 connected to it is also pulled to move synchronously: when the gear 132 moves to the position where it meshes with the teeth on the incomplete rack plate 134, the jet pipe 31 will rotate upward around its own rotation axis 21 by a certain angle under the meshing force of the teeth, thereby changing the jet direction; when the gear 132 continues to move with the jet pipe 31 and leaves the meshing range of the teeth on the incomplete rack plate 134, the hinged spring, which was originally in an energy storage state, will release its elastic potential energy and generate a reset force, driving the jet pipe 31 to quickly return to the initial angle.

[0085] As the lifting plate 13 continues to move vertically, the engagement of the gear 132, the rotation of the jet pipe 31, and the resetting of the spring occur in a continuous cycle, causing the jet pipe 31 to maintain a regular reciprocating oscillation while moving up and down. During this continuous oscillation, the jet direction of the jet pipe 31 constantly changes, thus blowing irregularly shaped and variable airflows onto the glass surface. When these irregular airflows act on the glass surface, they exert external forces of varying directions and magnitudes on the impurities attached to it, breaking the adsorption balance between the impurities and the glass surface. This makes it easier to peel off stubborn impurities that were originally difficult to remove, thereby significantly improving the cleaning effect on the glass surface.

[0086] Finally, the present invention also provides an automated cleaning production method for display modules, comprising the following steps:

[0087] S1: Placement preparation: Place the glass on the side of the mounting bracket 22 and use the vacuum suction cup 23 to fix the glass on the mounting bracket 22.

[0088] S2: Cleaning process. Start the lifting cylinder 12. During the upward movement of the extension end of the lifting cylinder 12, it drives the jet pipe 31 to move upward synchronously. During the movement of the jet pipe 31, the existing air pump is started to fill the jet pipe 31 with gas. The gas inside the jet pipe 31 is sprayed onto the glass through the jet hole, and the airflow can clean the impurities on the glass.

[0089] S3: Cleaning process, rotate the glass, start the electric slider 322. During the reciprocating movement of the electric slider 322 on the reciprocating frame 321, the connecting plate and the moving frame 32 work together to drive the cleaning frame 33 to reciprocate. During the reciprocating movement of the cleaning frame 33, the swing frame 35 is driven to wipe the glass surface. During the swinging process, the swing frame 35 can also expand the water flow guided by the guide rod 36 to clean the glass.

[0090] S4: Drying process. Rotate the glass back to the starting position and start the lifting cylinder 12 to drive the lifting plate 13 to move down. During the downward movement of the lifting plate 13, the jet pipe 31 blows the water stains on the glass surface, causing the water stains on the glass to move downward and eventually fall off the glass surface. During this process, the horizontal section of the linkage frame 43 drives the linkage plate 41 to move down. During the downward movement of the linkage plate 41, the sponge 42 can be driven to dry and wipe the water stains on the glass surface.

[0091] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
