Description

Technical Field

[0001] This invention relates to the field of display screen processing machinery technology, specifically to a smart manufacturing and cleaning equipment for computer displays. Background Technology

[0002] In the display manufacturing process, the glass substrate used in the process needs to be cleaned. The core purpose of cleaning is to remove particulate impurities, organic contaminants, metal ions and natural oxide layers from the substrate surface. If the above contaminants cannot be completely removed, they will directly affect the forming quality of subsequent key processes such as photolithography, thin film deposition and bonding, and thus cause problems such as reduced film adhesion, circuit fabrication defects and deterioration of display uniformity. Therefore, cleaning is used to ensure that the surface of the glass substrate reaches a high degree of cleanliness, which can effectively improve the overall quality of the finished display.

[0003] In summary, although existing glass substrate cleaning machines can achieve simultaneous spraying of the spraying mechanism and the glass substrate, the spraying intensity of the spraying mechanism is constant. Once the spraying valve is opened, the spraying pressure and flow rate remain fixed in a single cleaning process, making it impossible to adjust according to the different cleaning stages of the glass substrate. This can easily lead to excessive consumption of cleaning consumables.

[0004] To address this, we propose an intelligent manufacturing and cleaning device for computer displays. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a smart manufacturing cleaning device for computer displays. By contacting the extrusion block with a continuously gradually changing contour with the pressure plate, a proportional pressure regulating valve is driven to continuously adjust the flow rate and pressure of the cleaning fluid. This allows the spray pipe to sequentially complete the cleaning processes of contaminant wetting and loosening, high-intensity bubble stain removal, and surface residue rinsing during the glass substrate transport process. This avoids the problem of incomplete cleaning or substrate damage that can easily be caused by a single spray intensity, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a computer display screen intelligent manufacturing cleaning equipment, comprising a cleaning mechanism, wherein the cleaning mechanism includes a substrate cleaning machine, a drive motor is fixedly connected to one outer wall of the substrate cleaning machine, a gear is fixedly connected to the output end of the drive motor, a conveying chain is provided outside the gear, the conveying chain meshes with the gear, a plurality of connecting blocks are fixedly connected to the outer surface of the conveying chain, an extrusion block is fixedly connected to the inner wall of the substrate cleaning machine, and a bearing mechanism for carrying and conveying glass substrates is provided inside the substrate cleaning machine; In the above technical solution, the bearing mechanism includes a support frame, which is movably sleeved on the connecting block and can move with the conveyor chain. The inner wall of the support frame has a limit groove, and the outer surface of the support frame has a through hole. A boss is fixedly connected to the outer surface of the support frame near the through hole. A pressure plate is provided on the side of the support frame facing the extrusion block. A second ball is rotatably connected to the inner wall of the pressure plate, and the second ball rolls in contact with the outer surface of the extrusion block.

[0007] Preferably, a limiting block is fixedly connected to the outer wall of one end of the pressure plate near the support frame. The limiting block is slidably connected to the inner wall of the limiting groove. The limiting groove is used to limit the sliding distance of the pressure plate and to limit the sliding distance of the limiting block and the pressure plate, preventing excessive movement of the limiting block and the pressure plate, and limiting the initial and extreme positions of the limiting block and the pressure plate.

[0008] Preferably, the inner wall of the pressure plate is rotatably connected to a rotating rod via a rotating shaft, and the end of the rotating rod away from the pressure plate is rotatably connected to a sliding frame via a rotating shaft. The inner wall of the sliding frame is slidably connected to the support frame, and the sliding frame slides perpendicular to the support frame.

[0009] It is worth noting that a pressing plate is fixedly connected to the outer wall of the sliding frame at the end away from the rotating rod, and a tension spring is fixedly connected to the bottom of the pressing plate. The end of the tension spring near the pressing plate is fixedly connected to the support frame. The tension spring is used to provide a restoring force for the pressing plate and the pressure plate.

[0010] Based on the above, the outer wall of the substrate cleaning machine is fixedly connected to an inlet pipe, and several water distribution pipes are fixedly connected to the inlet pipe. Spray pipes are fixedly connected to the inner wall of the several water distribution pipes.

[0011] Meanwhile, a proportional pressure regulating valve is fixedly connected to the outer wall of the water distribution pipe near the spray pipe. The proportional pressure regulating valve is a push rod type proportional pressure regulating valve. By changing the stroke of the valve rod from bottom to top, the pressure and flow rate of the cleaning liquid in the spray pipe can be linearly controlled. The valve rod stroke has a stable linear correspondence with the fluid pressure and flow parameters, ensuring the stability of the adjustment during the cleaning process. The valve rod end of the proportional pressure regulating valve is connected to a first ball, which makes rolling contact with the outer surface of the extrusion plate.

[0012] Preferably, the substrate cleaning machine has a first drive roller and a second drive roller rotatably connected inside. The first drive roller and the second drive roller are located on the same horizontal axis and are used to assist in the movement of the support frame. The inner wall of the gear is connected to the first drive roller through a rotating shaft.

[0013] It is worth noting that the profile of the extrusion block along the conveying direction of the conveying chain is set with different gradients, so that the extrusion force on the pressure plate changes in a gradient during the movement.

[0014] Based on the above, when the pressure plate is squeezed by the extrusion block and moves towards the support frame, the sliding frame and the extrusion plate are pushed away from the support frame by the rotating rod. When the extrusion plate is pushed away from the support frame, the outer surface of the extrusion plate squeezes the first ball at the output end of the proportional pressure regulating valve to adjust the opening of the proportional pressure regulating valve, thereby controlling the flow rate and pressure of the cleaning liquid sprayed from the spray pipe.

[0015] Compared with existing technologies, it has the following beneficial effects: 1. In this intelligent manufacturing cleaning equipment for computer displays, the intensity of cleaning at different stages of the glass substrate is adjusted by the cooperation of the extrusion block and the pressure plate, thereby improving the cleaning effect while reducing the consumption of cleaning consumables.

[0016] 2. In this intelligent manufacturing cleaning equipment for computer displays, the squeezing action during the conveying process can be converted into control of the pressure and flow of the cleaning fluid by adjusting the proportional pressure regulating valve of the squeezing plate, thereby reducing the configuration cost of the control system and simplifying the equipment structure.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0021] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Because the existing glass substrate cleaning machine's spray mechanism can complete the follow-up spraying synchronously with the glass substrate, but its spray intensity is constant, the spray pressure and flow rate remain unchanged in a single cleaning process after the valve is opened, and it cannot be adapted and adjusted according to different cleaning stages, which leads to the problem of excessive consumption of cleaning consumables.

[0023] Therefore, in view of the above-mentioned problems, the present invention discloses a smart manufacturing cleaning device for computer displays, with reference to... Figure 1-3As shown, the system includes a cleaning mechanism 1, which includes a substrate cleaning machine 101. The substrate cleaning machine 101 has a cleaning chamber inside. A drive motor 102 is fixedly connected to one outer wall of the substrate cleaning machine 101. A gear 103 is fixedly connected to the output end of the drive motor 102. A conveyor chain 111 is provided outside the gear 103. The conveyor chain 111 is meshed with the gear 103. When the drive motor 102 is running, it drives the conveyor chain 111 to circulate through the gear 103. Several connecting blocks 112 are fixedly connected to the outer surface of the conveyor chain 111. The several connecting blocks 112 are evenly distributed along the length of the conveyor chain 111. An extrusion block 106 is fixedly connected to the inner wall of the substrate cleaning machine 101. A support mechanism 2 for carrying and conveying glass substrates is provided inside the substrate cleaning machine 101.

[0024] When a glass substrate needs to be rinsed, refer to Figure 2 As shown, an inlet pipe 107 is fixedly connected to the outer wall of the substrate cleaning machine 101. Several water distribution pipes 108 are fixedly connected to the inlet pipe 107. Spray pipes 113 are fixedly connected to the inner walls of the several water distribution pipes 108. The spray pipes 113 face the glass substrate on the support mechanism 2 and are used for spray cleaning. It is worth noting that a proportional pressure regulating valve 109 is fixedly connected to the outer wall of the water distribution pipes 108 near the spray pipes 113. The proportional pressure regulating valve 109 is a push rod type proportional pressure regulating valve. By changing the stroke of the valve rod from bottom to top, the pressure and flow rate of the cleaning liquid in the spray pipes 113 can be linearly controlled. It is worth noting that the valve rod stroke has a stable linear correspondence with the fluid pressure and flow rate parameters, ensuring the stability of the adjustment during the cleaning process. A first ball bearing 110 is rolled at the end of the valve rod of the proportional pressure regulating valve 109. The first ball bearing 110 can rotate freely and form rolling contact with the outer surface of the extrusion plate 210, thereby realizing mechanical stepless adjustment.

[0025] refer to Figure 2-3 As shown, the substrate cleaning machine 101 has a first drive roller 104 and a second drive roller 105 rotatably connected inside. The first drive roller 104 and the second drive roller 105 are located on the same horizontal axis, and the first drive roller 104 and the second drive roller 105 have the same diameter. Their surfaces are in contact with the bearing mechanism 2 to assist in supporting and guiding the movement of the support frame 201. The inner wall of the gear 103 is connected to the first drive roller 104 through a rotating shaft.

[0026] For details, please refer to the following: Figure 3 As shown, since the contour of the extrusion block 106 along the conveying direction of the conveyor chain 111 is set with different gradients, the distance between the outer surface of the extrusion block 106 and the inner wall of the substrate cleaning machine 101 is set to continuously vary (see details). Figure 3As shown in D1, D2, and D3, when the second ball 207 contacts different positions of the extrusion block 106, the pressure plate 205 is subjected to different extrusion forces, and the height of the extrusion plate 210 also changes accordingly (see details in D1, D2, and D3). Figure 4 (As shown in L1, L2, and L3).

[0027] When the second ball 207 on the outer surface of the pressure plate 205 slides to the left side of the compression block 106 (visible) Figure 3 When the pressure plate 210 is in the position shown in D1, the height of the pressure plate 210 rises by L1, which in turn slightly lifts the valve stem at the end of the proportional pressure regulating valve 109. At this time, the spray pipe 113 sprays out gentle and uniform bubbles to wet the glass substrate and initially loosen the contaminants.

[0028] When the second ball 207 on the outer surface of the pressure plate 205 slides to the middle area of ​​the extrusion block 106 (visible) Figure 3 When the pressure plate 210 is in position D2, the height of the pressure plate 210 rises by L2, which in turn fully lifts the valve stem at the end of the proportional pressure regulating valve 109. At this time, the spray pipe 113 sprays out high-intensity, high-density bubbles to thoroughly peel off and remove contaminants.

[0029] When the second ball 207 on the outer surface of the pressure plate 205 slides to the right side of the pressing block 106 (visible) Figure 3 When the pressure plate 210 is at position D3 (as shown in the figure), the height of the pressure plate 210 rises by L3, which pushes the valve stem at the end of the proportional pressure regulating valve 109 to the middle stroke position. At this time, the spray pipe 113 sprays low-intensity, high-flow-rate bubbles to rinse away the residue and prepare for the subsequent water washing operation.

[0030] refer to Figure 6-7 As shown, the supporting mechanism 2 includes a support frame 201, which is movably sleeved on the connecting block 112 and can move with the conveyor chain 111. The inner wall of the support frame 201 has a limiting groove 202, and the outer surface of the support frame 201 has a through hole 203. A boss 204 is fixedly connected to the outer surface of the support frame 201 near the through hole 203. The boss 204 is used to support and place the glass substrate. A pressure plate 205 is provided on the side of the support frame 201 facing the extrusion block 106. A second ball bearing 207 is rotatably connected to the inner wall of the pressure plate 205. When the second ball bearing 207 rolls into contact with the outer surface of the extrusion block 106, it can convert sliding friction into rolling friction, thereby reducing the resistance when the support frame 201 moves.

[0031] A limiting block 206 is fixedly connected to the outer wall of one end of the pressure plate 205 near the support frame 201. The limiting block 206 is slidably connected to the inner wall of the limiting groove 202. The limiting groove 202 is used to limit the sliding distance of the limiting block 206 and the pressure plate 205, prevent excessive movement of the limiting block 206 and the pressure plate 205, and limit the initial and extreme positions of the limiting block 206 and the pressure plate 205.

[0032] Meanwhile, the inner wall of the pressure plate 205 is rotatably connected to a rotating rod 208 via a rotating shaft. The end of the rotating rod 208 away from the pressure plate 205 is rotatably connected to a sliding frame 209 via a rotating shaft. The inner wall of the sliding frame 209 is slidably connected to the support frame 201, and the sliding frame 209 slides perpendicular to the support frame 201.

[0033] A pressing plate 210 is fixedly connected to the outer wall of the sliding frame 209 away from the rotating rod 208. A tension spring 211 is fixedly connected to the bottom of the pressing plate 210. The end of the tension spring 211 near the pressing plate 210 is fixedly connected to the support frame 201. The tension spring 211 is used to provide a restoring force for the pressing plate 210 and the pressure plate 205. When the pressure plate 205 is removed from the pressing area of ​​the pressing block 106, the pressing plate 210 retracts and the pressure plate 205 is reset under the tension of the tension spring 211. At the same time, the proportional pressure regulating valve 109 is also closed under the action of its internal spring, thereby stopping the spraying operation of the spray pipe 113.

[0034] refer to Figure 4-5 As shown, when the pressure plate 205 is pressed by the compression block 106 and moves towards the support frame 201, the rotating rod 208 pushes the sliding frame 209 and the compression plate 210 to move away from the support frame 201. Specifically, when the pressure plate 205 moves inward under pressure, it pushes the rotating rod 208 to swing, thereby driving the sliding frame 209 to slide along a direction perpendicular to the length of the support frame 201. Furthermore, when the compression plate 210 moves upward, the end face of the compression plate 210... The first ball 110 at the end of the valve stem of the proportional pressure regulating valve 109 will be pushed. By controlling the displacement of the extrusion plate 210, the pushing distance of the first ball 110 can be adjusted accordingly, thereby realizing the mechanical adjustment of the opening degree of the valve core inside the proportional pressure regulating valve 109. When the opening degree of the valve core of the proportional pressure regulating valve 109 changes, the flow rate and fluid pressure of the cleaning fluid flowing through the proportional pressure regulating valve 109 and delivered to the spray pipe 113 will be changed, thereby completing the continuous control of the intensity of the spraying operation.
