Description

Technical Field

[0001] This utility model relates to the field of TFT liquid crystal glass substrate production technology, and in particular to a TFT liquid crystal glass substrate packaging rack. Background Technology

[0002] TFT liquid crystal glass substrates are a core component of liquid crystal display panels, primarily used in the manufacture of TFT-LCDs (Thin Film Transistor Liquid Crystal Displays). The glass substrate directly affects the image quality of the liquid crystal display.

[0003] As the size of glass substrates increases, the difficulty of storing and packaging them also increases. Traditional A-frame glass holders can only allow for tilted placement of the glass panels, but cannot provide lateral support and positioning. Furthermore, a protective film needs to be wrapped around the entire A-frame to prevent contamination of the glass panels, leading to cumbersome packaging and transportation processes for large-size TFT LCD glass substrates and increasing the risk of damage. Utility Model Content

[0004] The purpose of this utility model is to provide a TFT LCD glass substrate packaging rack to solve the problems of cumbersome packaging and transportation of large-size TFT LCD glass substrates and the ease with which they are damaged.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a TFT liquid crystal glass substrate packaging rack, comprising:

[0006] The support device includes a base, a support platform and a front support frame. The base is provided with forklift holes. The support platform includes a bottom plate and a back plate. The back plate is arranged at an angle relative to the base and is perpendicular to the bottom plate. The TFT liquid crystal glass substrate is placed on the bottom plate of the support platform.

[0007] The side positioning module includes a first screw, a side top piece, a guide rod, a ratchet, and a pawl unit. A groove is provided on the side plate of the front support frame. The first screw is rotatably mounted on the side plate of the front support frame. The side top piece is threaded onto the first screw. The guide rod is located on the back of the side plate of the front support frame and passes through the side top piece. One end of the first screw passes through the groove and connects to the ratchet. A pawl unit is provided in the groove to limit the unidirectional rotation of the ratchet.

[0008] The clamping module includes a second screw and a pressure rod. The second screw passes through the pressure rod and is connected to a nut. The pressure rod contacts the surface of the TFT liquid crystal glass substrate.

[0009] As a further description of the above technical solution:

[0010] The bearing device is also equipped with a sealing module, which includes a first sprocket, a chain, a drive shaft, a curtain, and a drive sprocket. The first sprocket is located on one side of the front support frame and is rotatably mounted on the front support frame. The drive shaft is located in the rear support frame of the bearing device and is equipped with a second sprocket. The chain is connected to the first and second sprockets. The bearing device is equipped with a baffle for positioning the chain. The curtain is fixedly mounted on the chain. The drive sprocket is rotatably mounted on the front support frame and its shaft passes through the front support frame. The drive sprocket meshes with the chain.

[0011] As a further description of the above technical solution:

[0012] A tensioning unit is provided on the drive shaft. The tensioning unit includes a tensioning seat and a tensioning bolt. A bearing seat is sleeved on the drive shaft. The bearing seat is slidably connected to the tensioning seat. The tensioning bolt is threadedly connected to the tensioning seat. The bottom of the tensioning bolt contacts the bearing seat.

[0013] As a further description of the above technical solution:

[0014] A desiccant storage box is installed on the side wall of the front support frame.

[0015] As a further description of the above technical solution:

[0016] The pawl unit includes a pawl seat, a pawl, and an operating handle. The pawl is elastically connected inside the pawl seat, and the operating handle passes through a clearance hole on the surface of the pawl seat and is then connected to the pawl.

[0017] As a further description of the above technical solution:

[0018] A first pad is installed on the bottom plate, and a second pad is installed on the back plate.

[0019] As a further description of the above technical solution:

[0020] The clamping module also includes a screw seat and a quick-change pin. The second screw is inserted into the screw seat, and the quick-change pin passes through the screw seat and the second screw.

[0021] As a further description of the above technical solution:

[0022] The compression bar consists of several bar units, one bar unit is rotatably mounted on an adjacent bar unit, and the two adjacent bar units are fixed by a pin.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0024] 1. In this utility model, the side positioning module and the clamping module work together to prevent the glass plate from becoming loose, stacked unevenly, or shifted during subsequent transportation, effectively avoiding collision damage to large-size TFT LCD glass substrates during transportation.

[0025] 2. In this utility model, the side positioning module adopts a rotation and pressing method for positioning during the positioning process, and controls the first screw to be affected by the ratchet mechanism composed of ratchet and pawl units, so as to avoid the first screw from rotating during transportation and to avoid the side top part from loosening, thereby accurately controlling the positioning effect. In addition, the side positioning module does not extend beyond the side of the packaging frame, which facilitates the overall transportation of the packaging frame.

[0026] 3. In this utility model, to ensure the packaging frame has good sealing performance, a sealing module is provided on the supporting device. After the TFT LCD glass substrate is positioned using the side positioning module and the clamping module, the drive sprocket is rotated by the rotating shaft, causing the chain to move. The transmission shaft causes the chains on both sides of the front support frame to move synchronously, moving the curtain cloth stored in the cavity of the rear support frame to the surface of the front support frame and shielding the TFT LCD glass substrate. This effectively protects the TFT LCD glass substrate, eliminating the need to wrap a protective film around the surface of the packaging frame and improving packaging and transportation efficiency.

[0027] 4. In this utility model, the second screw is detachably installed in the screw seat through a quick-change pin. This not only enables quick replacement of the second screw, but also, due to the movable design of the second screw, there is space for the second screw to wobble and deform. This allows the uneven surface of the TFT LCD glass substrate stacked on the support platform after the pressure rod squeezes it to form a "floating" design, avoiding rigid contact with the TFT LCD glass substrate and protecting the TFT LCD glass substrate.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] Example 1

[0047] Please see Figure 1-8 This utility model provides a technical solution: a TFT LCD glass substrate packaging rack, comprising:

[0048] The support device 1 includes a base 11, a support platform 12 and a front support frame 13. The base 11 is provided with a forklift hole 111. The support platform 12 includes a bottom plate 121 and a back plate 122. The back plate 122 is arranged at an angle relative to the base 11 and is perpendicular to the bottom plate 121. The TFT liquid crystal glass substrate is placed on the bottom plate 121 of the support platform 12.

[0049] The side positioning module 2 includes a first screw 21, a side top member 22, a guide rod 23, a ratchet 24, and a pawl unit. A groove 131 is provided on the side plate of the front support frame 13. The first screw 21 is rotatably mounted on the side plate of the front support frame 13. The side top member 22 is threaded onto the first screw 21. The guide rod 23 is provided on the back of the side plate of the front support frame 13 and passes through the side top member 22. One end of the first screw 21 passes through the groove 131 and is connected to the ratchet 24. A pawl unit for limiting the unidirectional rotation of the ratchet 24 is provided in the groove 131.

[0050] The clamping module 3 includes a second screw 31 and a pressure rod 32. The second screw 31 passes through the pressure rod 32 and is connected to a nut. The pressure rod 32 contacts the surface of the TFT liquid crystal glass substrate.

[0051] The side positioning module 2 and the clamping module 3 work together to prevent the glass plates from becoming loose, stacked unevenly, or shifted during subsequent transportation, effectively avoiding collision damage to large-size TFT LCD glass substrates during transportation.

[0052] During the positioning process, the side positioning module 2 uses a rotational pressing method to squeeze and position the first screw 21. The first screw 21 is controlled by the ratchet mechanism composed of ratchet 24 and pawl unit to prevent the first screw 21 from rotating during transportation and to prevent the side top part 22 from loosening. This ensures precise control of the positioning effect. Furthermore, the side positioning module 2 does not extend beyond the side of the packaging frame, facilitating the overall transportation of the packaging frame.

[0053] A desiccant storage box 5 is provided on the side wall of the front support frame 13 to effectively control the internal air humidity after the packaging frame is sealed.

[0054] The pawl unit includes a pawl seat 25, a pawl 26, and an operating handle 27. The pawl 26 is elastically connected within the pawl seat 25, and the operating handle 27 passes through a clearance hole 251 on the surface of the pawl seat 25 and connects to the pawl 26. In its normal state, the pawl 26 abuts against the ratchet 24 to prevent the ratchet 24 from rotating in the opposite direction. When it is necessary to adjust the side pusher 22 to retract, the operating handle 27 is used to pull the pawl 26 backward, causing the pawl 26 to disengage from the ratchet 24, thereby unlocking it and allowing the first screw 21 to rotate in the opposite direction.

[0055] A first pad 1211 is provided on the base plate 121, and a second pad 1221 is provided on the back plate 122. The first pad 1211 is a PP foam board, and the second pad 1221 is a composite board composed of an EVA board and a PP foam board. The PP foam board is disposed on the surface of the EVA board, and the PP foam material contacts the TFT liquid crystal glass substrate, effectively protecting the TFT liquid crystal glass substrate.

[0056] Working principle: When the packaging rack stores the TFT LCD glass substrate, the robotic arm places the TFT LCD glass substrate on the support platform 12 of the carrying device 1. To prevent positional displacement during glass transportation, side positioning modules 2 are installed on both sides of the support platform 12 to position the TFT LCD glass substrate on both sides. Simultaneously, in a direction perpendicular to the back plate 122, the pressure rod 32 of the pressing module 3 presses down on the TFT LCD glass substrate to prevent it from detaching from the support platform 12. Finally, the forklift forks can be inserted into the forklift holes 111 of the base 11 to achieve overall transport of the packaging rack. The tilt angle of the back plate 122 relative to the base 11 is 70°-80°, preferably 72°±0.2°. The surface of the side top piece 22 is provided with rubber pads to prevent damage to the TFT LCD glass substrate. When positioning using the side positioning modules 2 on both sides of the support platform 12, the first screw 21 is rotated by the handle provided at the end of the first screw 21, so that the side top member 22 moves toward the side of the TFT liquid crystal glass substrate on the support platform 12 until the side top member 22 contacts the TFT liquid crystal glass substrate.

[0057] Example 2

[0058] Based on the above embodiments, this embodiment further improves upon the following technical solutions: A sealing module 4 is also provided on the bearing device 1. The sealing module 4 includes a first sprocket 41, a chain 42, a drive shaft 43, a curtain 44, and a drive sprocket 45. The first sprocket 41 is provided on one opposite side of the front support frame 13 and is rotatably mounted on the front support frame 13. The drive shaft 43 is located within the rear support frame 14 of the bearing device 1, and a second sprocket is provided on the drive shaft 43. The chain 42 is connected to the first sprocket 41 and the second sprocket. A baffle for positioning the outer shape of the chain 42 is provided on the bearing device 1, and the inner side of the chain 42 is filled with blocks to fully restrict the movement path of the chain 42. The curtain 44 is fixedly mounted on the chain 42. The drive sprocket 45 is rotatably mounted on the front support frame 13, and the shaft 451 of the drive sprocket 45 passes through the front support frame 13, engaging with the chain 42. Specifically, the shaft 451 can be driven by setting a concave keyway.

[0059] To ensure the packaging frame has good sealing performance, a sealing module 4 is provided on the support device 1. After the TFT LCD glass substrate is positioned using the side positioning module 2 and the clamping module 3, the drive sprocket 45 is rotated by the rotating shaft 451, causing the chain 42 to move. The transmission shaft 43 causes the chains 42 on both sides of the front support frame 13 to move synchronously, driving the curtain 44 stored in the cavity of the rear support frame 14 to move to the surface of the front support frame 13 and cover the TFT LCD glass substrate, effectively protecting the TFT LCD glass substrate. There is no need to wrap a protective film on the surface of the packaging frame, improving packaging and transportation efficiency.

[0060] Example 3

[0061] Based on the above embodiments, this embodiment further improves upon the following technical solution: a tensioning unit 46 is provided on the transmission shaft 43, the tensioning unit 46 includes a tensioning seat 461 and a tensioning bolt 462, a bearing seat 431 is sleeved on the transmission shaft 43, the bearing seat 431 is slidably connected to the tensioning seat 461, the tensioning bolt 462 is threadedly connected to the tensioning seat 461, and the bottom of the tensioning bolt 462 contacts the bearing seat 431.

[0062] The height of the bearing seat 431 on the drive shaft 43 is limited within the tensioning seat 461 by the tensioning bolt 462, thereby achieving the tensioning of the drive shaft 43.

[0063] Example 4

[0064] Based on the above embodiments, this embodiment further improves upon the following technical solution: the clamping module 3 also includes a screw seat 33 and a quick-change pin 34, the second screw 31 is inserted into the screw seat 33, and the quick-change pin 34 passes through the screw seat 33 and the second screw 31.

[0065] The second screw 31 is detachably installed in the screw seat 33 via the quick-change pin 34. This not only enables quick replacement of the second screw 31, but also allows for wobbling and deformation due to the movable design of the second screw 31. This creates a "floating" design when the pressure rod 32 presses the uneven surface of the TFT LCD glass substrate stacked on the support platform 12, avoiding rigid contact with the TFT LCD glass substrate and protecting the TFT LCD glass substrate.

[0066] Example 5

[0067] Based on the above embodiments, this embodiment further improves upon the following technical solution: the pressure rod 32 includes several rod units 321, one rod unit 321 is rotatably mounted on another adjacent rod unit 321, and the two adjacent rod units 321 are fixed by a pin.

[0068] This allows the pressure rod 32 to be folded and stored, and the folded pressure rod 32 can be placed in the gap between the support platform 12 and the front support frame 13 for easy storage.

[0069] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
