Description

Technical Field

[0001] This utility model relates to the technical field of LCD glass plate cleaning equipment, specifically to a material flipping mechanism for glass substrate cleaning equipment. It is mainly used to flip LCD glass substrates after top surface cleaning so that bottom surface cleaning can be carried out. Background Technology

[0002] The LCD glass substrate is a fundamental component of liquid crystal display devices. It is a thin sheet of glass produced using the float glass process, with an extremely smooth surface. It is the core component of LCD panels and is crucial to the electronic information display industry.

[0003] In the fabrication process of liquid crystal display devices, the corresponding LCD glass substrate first needs to undergo cleaning and drying pretreatment. Existing cleaning equipment for LCD glass substrate processing mainly includes a material conveying mechanism and an isolation cover mounted on top of the material conveying mechanism. The top surface of the LCD glass substrate is rinsed and dried using a rinsing mechanism and an air knife mechanism positioned at the front and rear of the material conveying mechanism, respectively. Then, after manual flipping, the LCD glass substrate, having undergone top-surface cleaning, is fed into the next cleaning equipment for bottom-surface cleaning. This process requires two sets of LCD glass substrate cleaning equipment, and the flipping process necessitates manual labor, thus increasing the risk of recontamination of the LCD glass substrate.

[0004] Therefore, the research objective of this utility model is to design a material flipping mechanism for a glass substrate cleaning equipment that can effectively achieve the flipping process of LCD glass substrates, so that the LCD glass substrates can be cleaned on both sides in one cleaning equipment, thereby significantly improving cleaning efficiency and ensuring cleaning effect. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a material turning mechanism for a glass substrate cleaning equipment, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A material turning mechanism for a glass substrate cleaning device includes:

[0008] The material conveying mechanism includes a frame and a first roller conveyor and a second roller conveyor mounted side by side on the frame. The first roller conveyor and the second roller conveyor have the same conveying direction, and the discharge end of the first roller conveyor and the feed end of the second roller conveyor are arranged in an intermittent state.

[0009] A fixed shaft is located on the frame below the discharge end of the first roller conveyor. A corresponding mesh conveyor belt is fixed to the rear side of the fixed shaft. A set of corresponding stop protrusions are provided at intervals on the rear side of the mesh conveyor belt. The rear end of the mesh conveyor belt is wound around the corresponding rotating shaft and connected to the corresponding drive shaft by the corresponding pull rope. The drive shaft is driven by the corresponding flipping motor.

[0010] A corresponding material sensor is installed on the frame between a set of the stop protrusions. When the material sensor detects that the front end of the LCD glass substrate enters between the set of stop protrusions through the discharge end of the corresponding first roller conveyor, the flipping motor starts to reverse to release the pull rope. The set of stop protrusions moves downward to flip the LCD glass substrate whose front end is clamped between the stop protrusions, so that the upper end of the LCD glass substrate flips backward and abuts against the feed end of the second roller conveyor. Then the flipping motor starts to rotate forward to wind and tighten the pull rope. After the LCD glass substrate is lifted in height, it is conveyed backward by the second roller conveyor.

[0011] The first roller conveyor includes first rollers mounted side-by-side on the frame, and the second roller conveyor includes second rollers mounted side-by-side on the frame. Both the first roller and the second roller are driven by corresponding roller drive motors.

[0012] Several corresponding guide shafts are installed side by side at the interval between the first roller conveyor and the second roller conveyor. The first roller of the first roller conveyor, the second roller of the second roller conveyor, and the guide shafts are respectively connected to the output shaft end of the roller drive motor by chain drive.

[0013] A corresponding counterweight rod is fixed to the bottom of the mesh conveyor belt on the rear side of the stop protrusion.

[0014] A corresponding buffer silicone layer is bonded and fixed to the outer end of the stop protrusion.

[0015] Advantages of this utility model:

[0016] 1) The discharge end of the first roller conveyor and the feed end of the second roller conveyor are spaced apart. A fixed shaft is fixed to the frame below the discharge end of the first roller conveyor, and a mesh conveyor belt with a set of stop flanges on its rear side is fixed to the rear side of the fixed shaft. The rear end of the mesh conveyor belt is wound around a corresponding shaft and connected to a corresponding drive shaft by a corresponding pull rope. When the front end of the LCD glass substrate enters between the set of stop flanges through the discharge end of the first roller conveyor, the flipping motor starts to reverse to release the pull rope. The set of stop flanges moves downward to flip the LCD glass substrate whose front end is clamped between the stop flanges, so that the upper end of the LCD glass substrate flips backward and abuts against the feed end of the second roller conveyor. Then the flipping motor starts to rotate forward to wind and tighten the pull rope. After the LCD glass substrate is lifted, it is conveyed backward by the second roller conveyor.

[0017] This allows for the effective flipping of LCD glass substrates, enabling double-sided cleaning of the LCD glass substrates in a single cleaning system, significantly improving cleaning efficiency; and preventing secondary contamination caused by flipping, thus effectively ensuring the cleaning effect.

[0018] 2) In this invention, several corresponding guide shafts are installed side-by-side and rotatably at the interval between the first and second roller conveyors. Through the intervention of these guide shafts, the first roller of the first roller conveyor, the second roller of the second roller conveyor, and the guide shafts can be directly connected to the output shaft of the same set of roller conveyor drive motors via chain drive. Thus, the first and second roller conveyors can be driven by a single set of roller conveyor drive motors, saving on the cost of manufacture and operation of this invention.

[0019] 3) A corresponding counterweight rod is fixed to the bottom of the mesh conveyor belt behind the stop protrusion of this utility model to ensure that when the flipping motor starts and reverses, a set of stop protrusions can smoothly form a downward movement, thereby effectively ensuring the practical effect of this utility model.

[0020] 4) A corresponding buffer silicone layer is bonded and fixed to the outer end of the stop protrusion of this utility model. Under the buffering effect of the buffer silicone layer, the mechanical damage to the LCD glass substrate material is reduced, thereby further ensuring the practical effect of this utility model.

[0024] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0025] refer to Figure 1-2 A material turning mechanism for a glass substrate cleaning equipment, comprising:

[0026] The material conveying mechanism 1 includes a frame 101 and a first roller conveyor 102 and a second roller conveyor 103 mounted side by side on the frame 101. The conveying directions of the first roller conveyor 102 and the second roller conveyor 103 are the same, and the discharge end of the first roller conveyor 102 and the feed end of the second roller conveyor 103 are spaced apart.

[0027] The fixed shaft 2 is located on the frame 101 below the discharge end of the first roller conveyor 102. A corresponding mesh conveyor belt 3 is fixedly connected to the rear side of the fixed shaft 2. A set of corresponding stop protrusions 4 are arranged at intervals on the rear side of the mesh conveyor belt 3. The rear end of the mesh conveyor belt 3 is wound around the corresponding rotating shaft 12 and then connected to the corresponding drive shaft 6 by the corresponding pull rope 5. The drive shaft 6 is driven by the corresponding flipping motor 7.

[0028] A corresponding material sensor 8 is installed on the frame 101 between a set of the stop convex edges 4. When the material sensor 8 detects that the front end of the LCD glass substrate enters between a set of the stop convex edges 4 through the discharge end of the corresponding first roller conveyor 102, the flipping motor 7 starts to reverse to release the pull rope 5. The set of stop convex edges 4 moves downward to flip the LCD glass substrate whose front end is stuck between the stop convex edges 4, so that the upper end of the LCD glass substrate flips backward and abuts against the feed end of the second roller conveyor 103. Then the flipping motor 7 starts to rotate forward to wind and tighten the pull rope 5. After the LCD glass substrate is lifted in height, it is conveyed backward by the second roller conveyor 103.

[0029] The discharge end of the first roller conveyor 102 and the feed end of the second roller conveyor 103 are set in an intermittent state. Then, a fixed shaft 2 is fixedly connected to the frame 101 on the lower side of the discharge end of the first roller conveyor 102. A grid-shaped conveyor belt 3 with a set of stop protrusions 4 on the rear side is fixedly connected to the rear side of the fixed shaft 2. The rear end of the grid-shaped conveyor belt 3 is wound around the corresponding rotating shaft 12 and then connected to the corresponding drive shaft 6 by the corresponding pull rope 5. When the front end of the LCD glass substrate enters between a set of stop flanges 4 via the discharge end of the corresponding first roller conveyor 102, the flipping motor 7 starts to reverse, releasing the pull rope 5. The set of stop flanges 4 descends to flip the LCD glass substrate whose front end is clamped between the stop flanges 4, causing the upper end of the LCD glass substrate to flip backward and abut against the feed end of the second roller conveyor 103. Then, the flipping motor 7 starts to rotate forward, winding and tightening the pull rope 5. After the LCD glass substrate is lifted to a higher height, it is conveyed backward by the second roller conveyor 103. This effectively achieves the flipping process of the LCD glass substrate, allowing the LCD glass substrate to be cleaned on both sides in one cleaning device, significantly improving cleaning efficiency. It also prevents secondary contamination caused by flipping, thus effectively ensuring the cleaning effect.

[0030] The first roller conveyor 102 includes a first roller mounted side by side on the frame 101, and the second roller conveyor 103 includes a second roller mounted side by side on the frame 101. Both the first roller and the second roller are driven by a corresponding roller drive motor 9.

[0031] Several corresponding guide shafts 10 are installed side by side at the interval between the first roller conveyor 102 and the second roller conveyor 103. The first roller of the first roller conveyor 102, the second roller of the second roller conveyor 103, and the guide shafts 10 are respectively connected to the output shaft end of the roller drive motor 9 by chain drive.

[0032] In this invention, several corresponding guide shafts 10 are rotatably mounted side-by-side at the interval between the first roller conveyor 102 and the second roller conveyor 103. Through the intervention of the guide shafts 10, the first roller of the first roller conveyor 102, the second roller of the second roller conveyor 103, and the guide shafts 10 can be directly connected to the output shaft of the same set of roller conveyor drive motors 9 via chain drive. Thus, the first roller conveyor 102 and the second roller conveyor 103 can be driven by a single set of roller conveyor drive motors 9, thereby saving on the cost and operating expenses of this invention.

[0033] A corresponding counterweight rod 11 is fixed to the bottom of the mesh conveyor belt 3 behind the stop convex edge 4. Under the action of the counterweight rod 11, it is ensured that when the flipping motor 7 starts to reverse, a set of stop convex edges 4 can smoothly form a downward movement, thereby effectively ensuring the practical effect of this utility model.

[0034] A corresponding buffer silicone layer is bonded and fixed to the outer end of the stop protrusion 4. Under the buffering effect of the buffer silicone layer, mechanical damage to the LCD glass substrate material is reduced, thereby further ensuring the practical effect of this utility model.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
