Description

Technical Field

[0001] This invention relates to the field of light guide plate processing technology, and in particular to a material unloading and stacking device for light guide plate processing. Background Technology

[0002] As a crucial component of optical devices, light guide plates require extremely high surface quality. Extra care must be taken during the unloading and stacking processes after processing, which traditionally rely heavily on manual operation. While some existing automated handling equipment alleviates the burden on manual labor to some extent, it generally suffers from inaccurate positioning and insufficient stability when handling large, easily scratched, thin materials like light guide plates. This can easily lead to scratches or cracks on the product surface, causing unnecessary losses.

[0003] Existing palletizing devices still have significant drawbacks in structural design and functional integration. Many devices rely solely on simple mechanical clamping, lacking precise control over clamping force, which can easily damage workpieces due to uneven force. Furthermore, conventional equipment consumes a lot of energy and lacks effective energy recovery mechanisms. In addition, most devices lack effective preventative measures against the inertial slippage that may occur during rapid lifting or sudden stops; the adsorption function often requires separate control and cannot adaptively adjust to workpiece weight and movement, posing safety hazards. Moreover, there is a lack of reliable emergency braking schemes in the event of a lifting mechanism failure, posing a risk of damage to equipment and products. Therefore, we propose a palletizing device for light guide plate processing to address these issues. Summary of the Invention

[0012] The beneficial effects of this invention are as follows: 1. In this invention, a material unloading and stacking device for processing light guide plates is described. By starting a first drive motor to drive a drive gear to rotate, the drive gear drives a transverse moving seat to move back and forth through meshing with a transverse rack. Then, a second drive motor is started to drive a mounting shaft and one of the transmission gears to rotate, and drives another transmission gear to rotate in the opposite direction. The two transmission gears drive a vertical beam to move up and down through meshing with the corresponding vertical rack, thereby driving the connecting plate to move up and down, realizing the position adjustment of the mounting plate and the clamping mechanism, thereby moving the mounting plate directly above the light guide plate and making the clamping mechanism located outside the light guide plate. Then, an electric push rod is started to drive multiple clamping plates to move closer to each other, realizing the clamping and fixing of the light guide plate. The clamping force is monitored by a pressure sensor. 2. In this invention, the unloading and palletizing device for light guide plate processing is described. By starting the first drive motor and the second drive motor, the mounting plate is moved up and down and horizontally to grasp and move the light guide plate, thereby realizing automated unloading and palletizing. During the up and down movement of the vertical beam, the connecting rod moves synchronously, and the counterweight plate moves in the opposite direction through the flexible belt. That is, when the vertical beam moves downward, it drives the counterweight plate to move upward, thereby converting the gravitational potential energy of the vertical beam into storage on the counterweight plate. When the vertical beam moves upward, the counterweight plate moves downward, thereby converting the gravitational potential energy of the counterweight plate into the power to drive the vertical beam to move upward, thereby reducing energy consumption. 3. In this invention, the unloading and palletizing device for light guide plate processing, during the process of gripping the light guide plate, due to the gravity of the mounting plate, clamping mechanism, and light guide plate, can drive the connecting cylinder to move downward relative to the piston disc, compressing the compression spring. Simultaneously, it drives the spiral column to move downward relative to the fixed cylinder. The fixed cylinder, through its cooperation with the spiral column, drives the spiral column to rotate while moving downward. Furthermore, through the meshing of the driving and driven bevel gears, it drives the two connecting shafts and two valve cores to rotate, allowing the compressed gas storage tank to connect to the bend pipe via the valve body, thus allowing the compressed air in the compressed gas storage tank to pass through... The high-pressure air enters the vacuum generator's inlet through the valve body and pipe. As it flows through the narrow opening, the reduced cross-sectional area causes a sharp increase in air velocity, converting pressure energy into high-speed kinetic energy. The Venturi effect occurs within the diffuser cavity. The high-speed jet adsorbs and carries away existing air molecules from the intake port. These air molecules mix with the jet and are carried to the outlet. This continuous process draws air out of the diffuser cavity, causing a rapid drop in gas pressure within the region, thus creating a stable, localized vacuum. This significantly increases the internal pressure of the intake pipe. The pressure is reduced, while the bottom of the light guide plate still bears normal atmospheric pressure. This pressure difference generates a strong vacuum suction force to hold the light guide plate in place, thus preventing it from falling off during stacking. Simultaneously, when the weight of the light guide plate changes, the downward movement of the connecting cylinder relative to the piston disc increases, thereby increasing the opening size between the valve core and the valve body. This increases the airflow velocity within the bend, providing greater suction force at the bottom of the suction pipe and preventing it from falling off. Furthermore, when the vertical beam accelerates upward or decelerates downward, the mounting plate, clamping mechanism, and light guide... The plate's own inertia will cause the piston disc to move further upward within the connecting cylinder, further compressing the compression spring. This increases the distance the connecting cylinder moves relative to the connecting plate, thereby increasing the opening size between the valve core and the valve body. This increases the airflow velocity within the bend, enhancing the adsorption force on the light guide plate. Furthermore, when driving the light guide plate to move rapidly upward, the large area of ​​the light guide plate will result in significant air resistance. This air resistance will cause the light guide plate to move further downward relative to the connecting plate, further enhancing the adsorption force and preventing the light guide plate from falling off. 4. In this invention, the unloading and stacking device for light guide plate processing uses a flexible belt to drive a fixed pulley to rotate, thereby driving the rotating shaft and rotating plate to rotate. The rotating plate drives the horizontal bar, vertical plate, and connecting frame to rotate synchronously. Under the action of centrifugal force, the connecting frame is thrown outward and moves horizontally towards the side closer to the vertical beam while driving the horizontal bar and vertical plate to rotate via a linkage rod. At the same time, it drives the horizontal plate and clamping plate to move closer to the vertical beam, and simultaneously drives the connecting column to slide inside the connecting cylinder, compressing the return spring. When the connecting cylinder and connecting column are in the vertical position... In the straight state, the return spring is compressed to its maximum. When the rotation speed of the shaft is high enough, the connecting cylinder rotates beyond the vertical state. Under the action of the return spring, the connecting column slides outward and drives the horizontal plate and the clamping plate to move closer to the vertical beam. This causes the clamping plate to engage in the groove of the vertical beam to fix the vertical beam. If the meshing of the transmission gear and the vertical rack fails, or if the second drive motor malfunctions and causes the vertical beam to fall downward, the rotation speed of the shaft continues to increase until the clamping plate engages in the groove to fix the vertical beam, thereby preventing a falling accident. 5. The material unloading and palletizing device for light guide plate processing described in this invention can realize automated material unloading and palletizing operations, significantly improving production efficiency. This device, through the setting of a longitudinal drive and lifting mechanism, can precisely adjust the position of the clamping mechanism to grasp the light guide plate, and uses a pressure sensor to monitor the clamping force in real time to avoid workpiece damage. During the handling process, the counterweight mechanism can convert and store the gravitational potential energy of the lifting component, effectively reducing overall energy consumption. More importantly, the device adaptively triggers and adjusts the vacuum adsorption force using the workpiece's own weight and motion inertia, generating a stable and reliable adsorption effect through the Venturi effect, effectively preventing the light guide plate from slipping during rapid movement or acceleration. Simultaneously, the device also integrates a safety protection mechanism that can quickly lock the lifting component in case of drive failure or accidental fall, greatly improving the safety and reliability of equipment operation.

[0023] In this embodiment, during use, the first drive motor 301 is started to drive the drive gear 303 to rotate. The drive gear 303, through meshing with the transverse rack 304, drives the transverse moving seat 2 to move back and forth. The second drive motor 506 is started to drive the mounting shaft 505 and one of the transmission gears 504 to rotate, and drives the other transmission gear 504 to rotate in the opposite direction. The two transmission gears 504, through meshing with the corresponding vertical rack 503, drive the vertical beam 501 to move up and down, thereby driving the connecting plate 601 to move up and down, realizing the position adjustment of the mounting plate 603 and the clamping mechanism 7, thereby moving the mounting plate 603 directly above the light guide plate and making the clamping mechanism 7 located outside the light guide plate. Then, the electric push rod 702 is started to drive multiple clamping plates 705 to move closer to each other, realizing the clamping and fixing of the light guide plate. The clamping force is monitored by the pressure sensor 703. By activating the first drive motor 301 and the second drive motor 506, the mounting plate 603 is moved up and down and horizontally, thereby grasping and moving the light guide plate, thus achieving automated unloading and stacking. During the up and down movement of the vertical beam 501, the connecting rod 403 moves synchronously, and the counterweight plate 401 moves in the opposite direction through the flexible belt 402. That is, when the vertical beam 501 moves downward, it drives the counterweight plate 401 to move upward, thereby converting the gravitational potential energy of the vertical beam 501 into the storage on the counterweight plate 401. When the vertical beam 501 moves upward, the counterweight plate 401 moves downward, thereby converting the gravitational potential energy of the counterweight plate 401 into the power to drive the vertical beam 501 to move upward, thus reducing energy consumption. During the process of grasping the light guide plate, the weight of the mounting plate 603, the clamping mechanism 7, and the light guide plate causes the connecting cylinder 602 to move downward relative to the piston disc 604, compressing the compression spring 610. Simultaneously, this causes the spiral column 608 to move downward relative to the fixed cylinder 607. The fixed cylinder 607, through its interaction with the spiral column 608, causes the spiral column 608 to rotate as it moves downward. This rotation, via the meshing of the driving bevel gear 609 and the driven bevel gear 808, drives the two connecting shafts 807 and the two valve cores 806 to rotate. This allows the compressed gas tank 9 to connect to the bend pipe 804 through the valve body 805, allowing the compressed air inside the compressed gas tank 9 to pass through the valve... The air body 805 and the tube body enter the air inlet 8013 of the vacuum generator 801. When this high-pressure air flows through the narrow opening, the cross-sectional area of ​​the narrow opening decreases, causing the air velocity to increase sharply, thus converting pressure energy into high-speed kinetic energy. The Venturi effect occurs in the diffusion cavity. The high-speed jet will adsorb and carry away the original air molecules in the intake port 8011. These air molecules will mix with the jet and be carried to the exhaust port 8012. This process continuously draws air out of the diffusion cavity, causing the gas pressure in this area to drop rapidly, thus forming a stable, localized vacuum state. This also significantly reduces the internal pressure of the intake pipe 802, and the... The bottom of the light guide plate still bears normal atmospheric pressure. This pressure difference generates a strong vacuum suction force to hold the light guide plate in place, thus preventing it from falling off during stacking. Simultaneously, when the weight of the light guide plate changes, the connecting cylinder 602 moves downward relative to the piston disc 604 at a greater angle, increasing the opening between the valve core 806 and the valve body 805. This increases the airflow velocity within the bend 804, providing greater suction force at the bottom of the suction pipe 802 and preventing it from falling off. Furthermore, when the vertical beam 501 accelerates upward or decelerates downward, the mounting plate 603, clamping mechanism 7, and light guide plate... Due to its inertia, the piston disc 604 will move further upward within the connecting cylinder 602, further compressing the compression spring 610. This increases the moving distance of the connecting cylinder 602 relative to the connecting plate 601, thereby increasing the opening size between the valve core 806 and the valve body 805. This increases the airflow velocity within the bend 804, enhancing the adsorption force on the light guide plate. Furthermore, when the light guide plate is driven to move rapidly upward, its large area results in significant air resistance, causing it to move further downward relative to the connecting plate 601 under the influence of this air resistance. This further enhances the adsorption force and prevents the light guide plate from falling off. The flexible belt 402 drives the fixed pulley 404 to rotate, thereby driving the rotating shaft 405 and the rotating plate 407 to rotate. The rotating plate 407 drives the horizontal bar 409, the vertical plate 411, and the connecting frame 408 to rotate synchronously. Under the action of centrifugal force, the connecting frame 408 is thrown outward and moves horizontally towards the side closer to the vertical beam 501 while driving the horizontal bar 409 and the vertical plate 411 to rotate via the linkage rod 410. At the same time, it drives the horizontal plate 412 and the clamping plate 416 to move closer to the vertical beam 501, and drives the connecting column 413 to slide inside the connecting cylinder 415, compressing the return spring 414. When the connecting cylinder 415 and the connecting column 413 are in a vertical state, the return spring 414... When the compression is at its maximum, and the rotation speed of the shaft 405 is high enough that the rotation of the connecting cylinder 415 exceeds the vertical state, the connecting column 413 slides outward under the action of the return spring 414, and drives the horizontal plate 412 and the clamping plate 416 to move closer to the vertical beam 501, so that the clamping plate 416 is engaged in the groove 502 of the vertical beam 501 to fix the vertical beam 501. If the meshing of the transmission gear 504 and the vertical rack 503 fails, or if the second drive motor 506 fails and causes the vertical beam 501 to fall downward, the rotation speed of the shaft 405 continues to increase until the clamping plate 416 is engaged in the groove 502 to fix the vertical beam 501, thereby avoiding a falling accident.
