Description

Technical Field

[0001] This invention relates to the technical field of panel handling, and more particularly to a panel handling rack and its handling method. Background Technology

[0002] During the manufacturing process of LCD panels, due to experimental or processing needs or the distance between upstream and downstream equipment, it is necessary to move LCD panels across areas within the workshop. When moving LCD panels, they need to be placed and moved by a transport rack. However, the internal size of LCD panel transport racks such as cassettes is usually fixed. That is, a cassette of a fixed size can only transport LCD panels that are compatible with its size.

[0003] However, a factory may produce LCD panels of different sizes as needed. When transporting them, if the size of the existing cassette is not suitable for the size of the LCD panels in the current production batch, it will inevitably increase the production time and cost if a cassette is customized separately. If an unsuitable cassette is used to transport the LCD panels, the LCD panels may break due to collision with the cassette during the transport process. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0011] As a preferred embodiment of the panel transport rack of the present invention, the pushing assembly includes a pushing frame disposed at the lower end of the shelf, a pushing cylinder disposed on the pushing frame, a sealing plug disposed on the inner wall of the pushing cylinder, and a support tube disposed through the sealing plug, wherein the support tube movably passes through the pushing cylinder and is connected to the air guide tube.

[0012] As a preferred embodiment of the panel transport rack of the present invention, the support assembly includes a support rod disposed on a mobile trolley, the support rod being an inverted "U" shape, a support frame symmetrically disposed at the lower end of the shelf, and clamping wheels symmetrically disposed about the support rod within the support frame, wherein the two clamping wheels clamp and roll onto the support rod.

[0013] In a preferred embodiment of the panel transport rack of the present invention, the adjustment unit includes a positioning component, and the positioning component is disposed on the adjustment component. The positioning component includes an air guiding component disposed on the pushing component and a transmission component disposed on the placement plate, and the air guiding component and the transmission component are connected.

[0014] As a preferred embodiment of the panel transporter of the present invention, the air guiding assembly includes a sealing sleeve movably sleeved on the push cylinder, an air vent hole provided on the cylinder wall of the push cylinder, and sealing rings provided on the inner tube walls at both ends of the sealing sleeve, and the sealing rings are slidably connected to the outer cylinder wall of the push cylinder.

[0015] As a preferred embodiment of the panel handling rack of the present invention, the transmission assembly includes a storage groove disposed on the vertical groove wall of one of the storage slots, a pressure strip disposed in the storage slot, one side of the pressure strip being movably disposed in the storage groove, a transmission rod disposed on the pressure strip, the transmission rod movably penetrating the storage plate and disposed on the outer tube wall of the sealing sleeve, a reset ring disposed on the rod wall of the transmission rod, and a spring disposed between the reset ring and the outer side of the storage plate.

[0016] As a preferred embodiment of the panel transport rack of the present invention, the adjustment unit further includes a prompting component, which is disposed on the positioning component. The prompting component includes a light alarm and a battery pack disposed on the outside of a shelf, and a triggering component disposed on the air guide assembly.

[0017] The triggering assembly includes a pressure roller disposed on the outer wall of the lower end of the sealing sleeve, a trigger groove disposed on the moving trolley, a self-resetting jog button switch disposed in the trigger groove, and two self-resetting jog button switches connected to the light alarm and the battery pack control, the two self-resetting jog button switches being arranged in series, and a pressure block disposed on the self-resetting jog button switch, the pressure block having an isosceles trapezoidal cross section, the upper end of the pressure block being disposed through the opening of the trigger groove.

[0018] The beneficial effects of this invention are as follows: The LCD panel is placed in the storage slot, and then the air pump is started. Air enters the area between the inner sealing plug and the bottom of the push cylinder through the support pipe, pushing the two storage plates to move towards each other. The distance between the two storage plates is adjusted according to the length of the LCD panel, thereby meeting the installation requirements of LCD panels of different sizes.

[0019] Another objective of this invention is to provide a panel handling method that is applicable to the handling needs of panels of different sizes.

[0020] To achieve the above objectives, the present invention provides the following technical solution: a panel handling method, the specific steps of which are as follows:

[0021] First, place the LCD panel in the storage slot between the two storage plates, then start the air supply unit;

[0022] The air pump will transport the air to the two guide pipes through the three-way pipe, and then to the push cylinder through the guide pipe and the support pipe. As the air pressure in the push cylinder increases, the push cylinder will push the shelf to move through the push assembly. The two shelf plates move towards each other and shorten the distance between them.

[0023] When the pressure strip on the shelf comes into contact with the LCD panel, the shelf continues to move due to the pushing force. The pressure strip is squeezed into the storage groove by the LCD panel. When the pressure strip moves, it drives the sealing sleeve to move synchronously on the push cylinder through the transmission rod. When the pressure strip enters the storage groove, the vent hole on the push cylinder exposes the sealing sleeve. The air that has entered the push cylinder is discharged through the vent hole. The push cylinder stays in place, thus stopping the shelf from moving.

[0024] The other shelf repeats the above steps until it stops moving. At this point, the distance between the two shelf slots on the two shelves matches the length of the LCD panel.

[0025] When the sealing sleeve moves, it also drives the pressure roller to roll on the moving trolley. When the vent hole exposes the sealing sleeve, the pressure roller also presses on the pressure block, thereby activating the self-reset jog button switch. When both self-reset jog button switches are activated, the battery pack supplies power to the light alarm, and the light alarm emits a light prompt to remind the operator that the position of the shelf has been adjusted and the next operation can be carried out.

[0026] The beneficial effects of this invention are: it automatically adjusts its own size according to the length of the panel, which can be applied to the handling needs of panels of different sizes. Attached Figure Description

[0040] Example 1

[0041] Reference Figure 1-4This invention provides a panel transport rack and its transport method in its first embodiment. The device includes a moving unit 1, which comprises a moving trolley 11, two L-shaped storage plates 12 movably mounted on the moving trolley 11, and a plurality of L-shaped storage slots 13 evenly spaced on the storage plates 12. Multiple support rollers 14 are rotatably connected within the horizontal grooves of the storage slots 13 to reduce frictional resistance during relative movement between the storage plates 12 and the liquid crystal panel.

[0042] The adjustment unit 2 includes a drive slot 21 opened on the mobile trolley 11, an adjustment component 22 installed in the drive slot 21, and the adjustment component 22 is connected to the two storage plates 12 in a transmission manner. The adjustment component 22 includes an air supply component 221 installed in the drive slot 21, two push components 222 installed at the lower end of the two storage plates 12, and the air supply component 221 is connected to the two push components 222, as well as two support components 223 symmetrically installed at the lower end of the two storage plates 12.

[0043] The air supply assembly 221 includes an air pump 2211 installed at the bottom of the drive slot 21, a three-way pipe 2212 connected to the output end of the air pump 2211, and two air guide pipes 2213 detachably connected to the two output ends of the three-way pipe 2212. A one-way valve is installed on the air guide pipe 2213 so that the gas in the air guide pipe 2213 can only move in one direction.

[0044] The pushing assembly 222 includes a pushing frame 2221 connected to the lower end of the shelf 12, a pushing cylinder 2222 connected to the pushing frame 2221, a sealing plug 2223 slidably connected to the inner wall of the pushing cylinder 2222, and a support tube 2224 connected through the sealing plug 2223. The support tube 2224 movably passes through the pushing cylinder 2222 and is detachably connected to the air guide tube 2213. The gas in the air guide tube 2213 is transported to the pushing cylinder 2222 through the support tube 2224. Due to the seal inside the sealing plug 2223, the air pressure inside the pushing cylinder 2222 continuously increases, pushing the pushing cylinder 2222 and the sealing plug 2223 to make relative displacement. When the pushing cylinder 2222 moves, it pushes the shelf 12 to move synchronously through the pushing frame 2221. The two shelf 12 move towards each other to adjust the spacing, thereby adapting to the installation requirements of LCD panels of different sizes and avoiding breakage of the LCD panels due to collision with the cassette during transportation.

[0045] During use, the LCD panel is placed in the storage slot 13, and then the air pump 2211 is started. The air output by the air pump 2211 is transported to the two air guide pipes 2213 through the three-way pipe 2212. The air entering the air guide pipes 2213 then enters the area between the sealing plug 2223 and the bottom of the push cylinder 2222 through the support pipe 2224. As the air in this area increases, the air pressure increases. Under the action of the air pressure, the two push cylinders 2222 move towards each other. When the two push cylinders 2222 move, they drive the two storage plates 12 to move towards each other through the two push frames 2221. The distance between the two storage plates 12 is adjusted according to the length of the LCD panel to meet the installation requirements of LCD panels of different sizes.

[0046] The support component 223 includes a support rod 2231 connected to the mobile trolley 11. The support rod 2231 is inverted "U" shaped and symmetrically connected to four support frames 2232 at the lower end of the shelf 12. Clamping wheels 2233 are symmetrically installed in the support frames 2232 about the support rod 2231. Two clamping wheels 2233 clamp and roll on the support rod 2231. The clamping wheels 2233 cannot detach from the support rod 2231. The shelf 12 is supported by the clamping wheels 2233 that clamp the support rod 2231. When the shelf 12 moves under the force of the pushing component 222, the clamping wheels 2233 move synchronously on the support rod 2231 through the support frames 2232, thereby improving the moving stability of the shelf 12.

[0047] Example 2

[0048] Reference Figure 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the adjustment unit 2 includes a positioning component 23, and the positioning component 23 is connected to the adjustment component 22. The positioning component 23 includes an air guiding component 231 installed on the pushing component 222, and two transmission components 232 installed on the two placement plates 12. The air guiding component 231 and the corresponding transmission component 232 are connected.

[0049] The air guiding assembly 231 includes a sealing sleeve 2311 movably sleeved on the push cylinder 2222, a vent hole 2312 opened on the cylinder wall of the push cylinder 2222, through which air entering the push cylinder 2222 can be discharged, and a sealing ring 2313 connected to the inner tube wall at both ends of the sealing sleeve 2311. The sealing ring 2313 is slidably connected to the outer cylinder wall of the push cylinder 2222. When the vent hole 2312 is between the two sealing rings 2313, the air entering the push cylinder 2222 can no longer be discharged after entering the sealing sleeve 2311.

[0050] The transmission assembly 232 includes a storage slot 2321 formed on the vertical wall of one of the storage slots 13, a pressure strip 2322 movably disposed in the storage slot 13, with one side of the pressure strip 2322 movably inserted into the storage slot 2321, a transmission rod 2323 connected to the pressure strip 2322, the transmission rod 2323 movably passing through the storage plate 12 and connected to the outer wall of the sealing sleeve 2311, a reset ring 2324 sleeved on the wall of the transmission rod 2323, and a spring 2325 connected between the reset ring 2324 and the outer side of the storage plate 12. The spring 2325 is sleeved on the transmission rod 2323. When the transmission rod 2323 moves, it drives the reset ring 2324 to move synchronously and stretches the spring 2325. When the transmission assembly 232 is no longer under force, the deformed spring 2325 drives the transmission assembly 2322 to reset.

[0051] During use, a liquid crystal panel is first placed in one of the two storage slots 13 containing two transmission components 232. When the push cylinder 2222 moves the storage plate 12, it also moves the positioning component 23 synchronously until the liquid crystal panel in the storage slot 13 presses against the pressure bar 2322. After the pressure bar 2322 is resisted by the liquid crystal panel, it moves relative to the storage plate 12. At the same time, the pressure bar 2322 enters the storage slot 2321. Simultaneously, the pressure bar 2322 applies a pulling force to the sealing sleeve 2311 through the transmission rod 2323. The sealing sleeve 2311 moves relative to the push cylinder 2222. When the pressure strip 2322 is fully inserted into the storage slot 2321, one side of the LCD panel is also in contact with the vertical wall of the storage slot 13. At the same time, the sealing sleeve 2311 exposes the vent hole 2312. At this time, the air that continues to enter the push cylinder 2222 can be discharged through the vent hole 2312 and will no longer push the storage plate 12 to move, so that the storage plate 12 remains in place until the storage plate 12 on the other side also repeats the above steps and stops moving. The distance between the storage slots 13 on the two storage plates 12 matches the length of the LCD panel, and then the remaining LCD panels are placed.

[0052] The remaining structure is the same as that in Example 1.

[0053] Example 3

[0054] Reference Figure 1-6 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the adjustment unit 2 further includes a prompting component 24, and the prompting component 24 is installed on the positioning component 23. The prompting component 24 includes a light alarm 241 and a battery pack 242 connected to the outside of a shelf 12, and a triggering component 243 installed on the air guide assembly 231.

[0055] The trigger assembly 243 includes a pressure roller 2431 installed on the outer wall of the lower end of the sealing sleeve 2311, a trigger groove 2432 opened on the moving trolley 11, a self-resetting jog button switch 2433 installed in the trigger groove 2432, and two self-resetting jog button switches 2433 are connected to the light alarm 241 and the battery pack 242 for control. The two self-resetting jog button switches 2433 are arranged in series, and a pressure block 2434 is connected to the self-resetting jog button switch 2433. The cross-section of the pressure block 2434 is an isosceles trapezoid. The upper end of the pressure block 2434 is set through the slot of the trigger groove 2432. A protective cloth cover is connected to the self-resetting jog button switch 2433 to prevent dust from entering the trigger groove 2432.

[0056] During use, the movement of the sealing sleeve 2311 also drives the pressure roller 2431 to move synchronously. When the sealing sleeve 2311 exposes the vent hole 2312, the pressure roller 2431 also presses on the pressure block 2434. The pressure block 2434 applies pressure to the self-reset jog button switch 2433, activating the self-reset jog button switch 2433. When both shelves 12 are in place and stop moving, the two self-reset jog button switches 2433 are also activated simultaneously. The series circuit formed by the light alarm 241, the battery pack 242, and the two self-reset jog button switches 2433 is then connected. The battery pack 242 supplies power to the light alarm 241, and the light alarm 241 emits a light to indicate that the shelf 12 has been adjusted and the LCD panel can be placed there.

[0057] The remaining structure is the same as that in Example 2.

[0058] Example 4

[0059] Reference Figure 1-6 The third embodiment of the present invention provides a panel handling method, the specific steps of which are as follows:

[0060] S1: First, place the LCD panel in the storage slot 13 between the two storage plates 12, and then start the air pump 2211 of the air supply assembly 221;

[0061] S2: The air pump 2211 transports air to the two air guide pipes 2213 through the three-way pipe 2212, and then transports it to the push cylinder 2222 through the air guide pipe 2213 and the support pipe 2224. As the air pressure in the push cylinder 2222 increases, the push cylinder 2222 pushes the shelf 12 to move through the push assembly 222, and the two shelf 12 move towards each other to shorten the distance between them.

[0062] S3: When the pressure strip 2322 on the shelf 12 comes into contact with the LCD panel, the shelf 12 continues to move due to the pushing force. The pressure strip 2322 is squeezed into the storage groove 2321 by the LCD panel. When the pressure strip 2322 moves, it drives the sealing sleeve 2311 to move synchronously on the push cylinder 2222 through the transmission rod 2323. When the pressure strip 2322 enters the storage groove 2321, the vent hole 2312 on the push cylinder 2222 exposes the sealing sleeve 2311. The air that enters the push cylinder 2222 is discharged through the vent hole 2312. The push cylinder 2222 stays in place, thereby stopping the shelf 12 from moving.

[0063] S4: Repeat the above steps on the other shelf 12 until it stops moving. At this time, the distance between the two shelf slots 13 on the two shelves 12 matches the length of the LCD panel.

[0064] S5: When the sealing sleeve 2311 moves, it will also drive the pressure roller 2431 to roll on the moving trolley 11. When the vent 2312 exposes the sealing sleeve 2311, the pressure roller 2431 also presses on the pressure block 2434, thereby activating the self-reset jog button switch 2433. When both self-reset jog button switches 2433 are activated, the battery pack 242 supplies power to the light alarm 241, and the light alarm 241 emits a light prompt to remind the operator that the position of the shelf 12 has been adjusted and the next operation can be carried out.

The two shelf plates move towards each other and shorten the distance between them. When the pressure strip on the shelf comes into contact with the LCD panel, the shelf continues to move due to the pushing force. The pressure strip is squeezed into the storage groove by the LCD panel. When the pressure strip moves, it drives the sealing sleeve to move synchronously on the push cylinder through the transmission rod. When the pressure strip enters the storage groove, the vent hole on the push cylinder exposes the sealing sleeve. The air that has entered the push cylinder is discharged through the vent hole. The push cylinder stays in place, thus stopping the shelf from moving. The other shelf repeats the above steps until it stops moving. At this point, the distance between the two shelf slots on the two shelves matches the length of the LCD panel. When the sealing sleeve moves, it also drives the pressure roller to roll on the moving trolley. When the vent hole exposes the sealing sleeve, the pressure roller also presses on the pressure block, thereby activating the self-reset jog button switch. When both self-reset jog button switches are activated, the battery pack supplies power to the light alarm, and the light alarm emits a light prompt to remind the operator that the position of the shelf has been adjusted and the next operation can be carried out.
