Description

Technical Field

[0001] This utility model relates to the field of liquid crystal panel processing technology, and more specifically, to a display panel receiving system. Background Technology

[0002] As the core component of a display, the manufacturing process of an LCD panel involves three main stages: the front-end array process, the mid-end cell process, and the back-end module assembly, encompassing over 300 precision processes. At the end of the entire process, the completed LCD panels need to be safely and systematically collected and stored, making automated display panel receiving systems a crucial link in ensuring production efficiency and product quality.

[0003] In the LCD panel manufacturing industry, the material receiving process has long faced technological challenges. Traditional receiving methods largely rely on manual operation, with operators directly handling the delicate panels for sorting and stacking. This manual operation mode has significant limitations. On the one hand, the efficiency of personnel is limited by physiological functions and experience levels, making it difficult to match the pace of high-speed continuous production, and fluctuations in workload can easily lead to unstable production cycles. On the other hand, repeated handling and contact by hand can easily cause scratches, micro-damage, or electrostatic damage to the delicate panel surfaces; these hidden defects directly affect the final product yield.

[0004] In addition, if the rack (or strip rack) used to support the panel has defects, such as the gap between the rack and toothed teeth not matching the panel size, it may collide with the panel during the material receiving process, causing product damage.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a display panel receiving system to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] The display panel receiving system includes: a housing; a three-axis robotic arm located on one side of the housing for transferring processed LCD panels into an LCD panel tray; support vertical plates located on one side inside the housing, with partitions between adjacent support vertical plates; a tray storage mechanism located on one side of the support vertical plates for storing LCD panel trays and enabling vertical lifting and lowering; a back plate located on one side of the top of the housing, with a transverse track on its end face; a tray translation mechanism located inside the transverse track for picking up LCD panel trays and enabling horizontal translation; the tray translation mechanism includes an arc-shaped slide plate located inside the transverse track, with a transverse motor located in the middle of the end face of the arc-shaped slide plate, and a gear that meshes with a rack and pinion at the output end of the transverse motor; connecting plates on both sides of the end face of the arc-shaped slide plate, with an L-shaped top plate at the end of the connecting plate away from the arc-shaped slide plate, and electrically controlled suction cups at the four corners of the bottom of the L-shaped top plate; and a control panel located on the top of the housing end face.

[0009] Furthermore, to achieve continuous cyclical collection of LCD panels using a liftable tray support, an empty LCD panel tray is placed above a full LCD panel tray, and lowered by a lifting motor, ensuring the top LCD panel tray remains at a fixed height for easy collection by the three-axis robotic arm. The tray storage mechanism includes mounting seats at the top and bottom of one side of the supporting vertical plate, with fixed covers fitted around the two mounting seats. Fixed plates are located at the top and bottom of the fixed covers, and a lifting motor is located at the top of the bottom fixed plate. A threaded rod is located at the top output end of the lifting motor, and the top of the threaded rod is movably connected to the fixed plate at the top. Vertical slots are provided on both sides of the fixed cover, and tray supports penetrating the vertical slots are provided on both sides of the fixed cover. A threaded sleeve that mates with the threaded rod is provided inside the tray support, and a tray support plate is provided on the outside of the tray support.

[0010] Furthermore, in order to limit the LCD panel tray and prevent it from shifting during the transfer process, thus ensuring the accuracy of receiving the material, both the fixing cover and the tray bracket are U-shaped structures, and the top four corners of the tray support plate are provided with limiting sides.

[0011] Furthermore, in order to ensure the vertical fixation and lateral translation drive of the pallet translation mechanism, the lateral track is a frame structure, and slide rails are provided at the bottom and top of the lateral track, and racks are provided laterally inside the lateral track.

[0012] Furthermore, in order to manually adjust the height and position of the electric suction cups according to the size of the LCD panel tray, change the spacing between different electric suction cups, and improve the adaptability of the device, an adjustable groove is provided on the vertical top of the L-shaped top plate. The adjustable groove is fixedly connected to the connecting plate by bolts. Multiple movable grooves are provided on the horizontal top of the L-shaped top plate. The electric suction cups are movably connected to the movable grooves to adjust the position and spacing of different electric suction cups.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the coordinated operation of the three-axis robotic arm, the pallet translation mechanism, and the pallet storage mechanism, the material receiving process is automated. When the pallets in the panel picking area are about to be full, the pallet translation mechanism can automatically pick up empty pallets from the pallet storage area and accurately transfer and stack them on top of the full pallets. The pallet storage mechanism in the panel picking area ensures that the top empty pallet is always accurately reset to the preset material placement position of the three-axis robotic arm, thereby achieving seamless connection of different pallet receiving operations. This allows the three-axis robotic arm to operate continuously without waiting, eliminating production line downtime caused by traditional manual pallet changing and greatly ensuring the continuous and stable operation of the high-speed LCD panel production line.

[0015] 2. This utility model effectively ensures the product quality of fragile LCD panels during the receiving process. The entire receiving process is completed by automated actuators such as a three-axis robotic arm, minimizing the risk of surface scratches, fingerprint contamination, or electrostatic damage that may be caused by direct contact between operators and the panels. At the same time, the tray storage mechanism can effectively limit the placement of the LCD panel tray, preventing it from shifting or colliding during lifting or lateral movement. The tray translation mechanism operates smoothly, ensuring the stability of the tray during the transfer process. This reduces the risk of the panels being scratched or broken during the receiving process from multiple aspects, which is conducive to improving the yield of the final product.

[0016] 3. By automating the entire material receiving process, the manual input required for this workstation can be significantly reduced, directly lowering long-term labor and management costs, improving the versatility of the equipment, demonstrating significant flexible production capabilities when facing multi-variety, small-batch production tasks, reducing the equipment modification costs and time required for product changeovers, and improving the overall economic efficiency of the production line.

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a display panel receiving system is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, the display panel receiving system according to an embodiment of the present invention includes: a housing 1; a three-axis robotic arm 2 located on one side of the housing 1, used to transfer processed liquid crystal panels to the inside of a liquid crystal panel tray; a supporting vertical plate 3 disposed on one side inside the housing 1, and a partition 4 is provided between two adjacent supporting vertical plates 3; a tray storage mechanism 5 disposed on one side of the supporting vertical plate 3, used to store the liquid crystal panel tray and realize vertical lifting movement; a back plate 6 disposed on one side of the top of the housing 1, and a transverse track 7 is provided on the end face of the back plate 6; a tray translation mechanism 8 disposed inside the transverse track 7, used to pick up the liquid crystal panel tray and realize horizontal movement; and a control panel 9 disposed on the top of the end face of the housing 1.

[0028] By utilizing the aforementioned technical solution, the automated material receiving process is achieved through the coordinated operation of the three-axis robotic arm 2, the pallet translation mechanism 8, and the pallet storage mechanism 5. When the pallets in the panel picking area are about to be full, the pallet translation mechanism 8 can automatically pick up empty pallets from the pallet storage area and accurately transfer and stack them on top of the full pallets. The pallet storage mechanism 5 in the panel picking area ensures that the top empty pallet is always accurately reset to the preset material placement position of the three-axis robotic arm 2, thereby achieving seamless connection of different pallet receiving operations. This allows the three-axis robotic arm 2 to operate continuously without waiting, eliminating production line interruptions caused by traditional manual pallet changing and greatly ensuring the continuous and stable operation of the high-speed LCD panel production line. This invention effectively ensures the product quality of fragile LCD panels during the receiving stage. The entire receiving process is completed by automated actuators such as the three-axis robotic arm 2, minimizing surface scratches, fingerprint contamination, or electrostatic damage that may be caused by direct contact between operators and the panels. Simultaneously, the tray storage mechanism 5 effectively limits the placement of the LCD panel tray, preventing displacement or collision during lifting or lateral movement. The tray translation mechanism 8 operates smoothly, ensuring the stability of the tray during transfer. These multiple aspects reduce the risk of panels being scratched or broken during receiving, thus improving the yield of the final product. By achieving full automation of the receiving stage, the manual labor required at this station can be significantly reduced, directly lowering long-term labor and management costs. It also enhances the versatility of the equipment, demonstrating significant flexible production capabilities when facing multi-variety, small-batch production tasks. Furthermore, it reduces the equipment modification costs and time required for product changeovers, improving the overall economic efficiency of the production line.

[0029] In one embodiment, for the aforementioned housing 1, in order to remove the LCD panel tray, the bottom end face of the housing 1 is provided with a plurality of equidistant material picking doors 10, and the number and position of the material picking doors 10 correspond one-to-one with the support vertical plate 3, so that the LCD panel tray filled at the top of the tray storage mechanism 5 can be removed through the material picking doors 10.

[0030] It should be noted that the interior of the housing 1 is divided into several independent areas by partitions 4, each equipped with a separate tray storage mechanism 5. Within the housing 1, these independent areas can be further divided into a tray storage area and a panel picking area. The area closest to the three-axis robotic arm 2 serves as the panel picking area, where the robotic arm 2 collects processed LCD panels. The tray storage area serves only as a storage area for empty LCD panel trays. Only when the top tray of the panel picking area is full is the empty LCD panel tray transferred to the panel picking area by the tray translation mechanism 8.

[0031] In one embodiment, the pallet storage mechanism 5 includes mounting bases 501 disposed at the top and bottom of one side of the supporting vertical plate 3, and a fixing cover 502 sleeved on the outer side of the two mounting bases 501; a fixing plate 503 is disposed at the top and bottom of the fixing cover 502, and a lifting motor 504 is disposed at the top of the fixing plate 503 located at the bottom, and a threaded rod 505 is disposed at the top output end of the lifting motor 504, and the top end of the threaded rod 505 is movably connected to the fixing plate 503 located at the top; vertical grooves 506 are provided on both sides of the fixing cover 502. The fixed cover 502 is provided with tray supports 507 that pass through the vertical groove 506 on both sides. The inner side of the tray support 507 is provided with a threaded sleeve 508 that cooperates with the threaded rod 505. The outer side of the tray support 507 is provided with a tray support plate 509. With the help of the liftable tray support 507, the LCD panel can be continuously collected in a cycle. That is, the empty LCD panel tray is placed on top of the full LCD panel tray, and the tray moves downward under the action of the lifting motor 504, so that the top LCD panel tray is always at a fixed height, which is convenient for the three-axis robotic arm 2 to collect the material.

[0032] In one embodiment, both the fixing cover 502 and the tray support 507 are U-shaped structures. The four corners of the top of the tray support plate 509 are provided with limiting sides 510 to limit the LCD panel tray, prevent displacement during the transfer process, and ensure the receiving accuracy.

[0033] In one embodiment, the transverse track 7 is a frame structure, and slide rails 11 are provided at both the bottom and top of the transverse track 7. A rack 12 is provided horizontally inside the transverse track 7, thereby ensuring the vertical fixation and horizontal translation drive of the pallet translation mechanism 8.

[0034] In one embodiment, the pallet translation mechanism 8 includes an arc-shaped slide plate 801 disposed inside the transverse track 7. A transverse motor 802 is disposed at the middle position of the end face of the arc-shaped slide plate 801, and a gear 803 that meshes with the rack 12 is disposed at the output end of the transverse motor 802. Connecting plates 804 are disposed on both sides of the end face of the arc-shaped slide plate 801. An L-shaped top plate 805 is disposed at the end of the connecting plate 804 away from the arc-shaped slide plate 801. An electrically controlled suction cup 806 is disposed at each of the four corners of the bottom of the L-shaped top plate 805, so that the empty LCD panel tray at the top of the pallet storage area can be transferred to the top of the full LCD panel tray through the electrically controlled suction cup 806, and the LCD panels can be collected again.

[0035] In one embodiment, the L-shaped top plate 805 has an adjustable groove 807 at its vertical top, which is fixedly connected to the connecting plate 804 by bolts. The L-shaped top plate 805 also has multiple movable grooves 808 at its horizontal top, and the electrically controlled suction cups 806 are movably connected to the movable grooves 808 to adjust the position spacing of different electrically controlled suction cups 806. This allows the height and position of the electrically controlled suction cups 806 to be manually adjusted according to the size of the LCD panel tray, thereby changing the spacing between different electrically controlled suction cups 806 and improving the adaptability of the device.

[0036] It should be noted that, to ensure the reliability and safety of the automated process, this invention also requires the introduction of various sensors commonly used and essential in the field. For example, limit switches are installed at the upper and lower limit positions of the lifting path of each pallet storage mechanism 5 to prevent the pallet support 507 from exceeding its lifting range, providing rigid safety protection. A vacuum pressure switch is installed in the pipeline of the electrically controlled suction cup 806 of the pallet translation mechanism 8 to detect whether a sufficient vacuum has been successfully established when the pallet is being picked up, thereby determining whether the picking is successful and avoiding accidents such as empty grabbing or the pallet falling halfway. In addition, a sensor is installed at the end of the three-axis robotic arm 2 to confirm whether the panel has been successfully picked up. To achieve more precise position control, a simple rotary encoder is configured for the lifting motor 504 and the transverse motor 802. The distance of movement is indirectly controlled by measuring the number of rotations of the motor, ensuring the accuracy of pallet translation and lifting positioning.

[0037] Furthermore, automatic counting of LCD panels in the panel picking area can be achieved using a machine vision-based inspection scheme. An industrial camera captures images of the tray, which are then analyzed by image processing software to count the number of panels. An industrial vision sensor (typically including an industrial camera, lens, and light source, not shown in the diagram) is installed above the panel picking area, directly opposite the tray. An appropriate resolution camera, such as a 5-megapixel industrial camera, is chosen to ensure clear capture of the outline of each LCD panel. A high-definition lens with a focal length of approximately 35mm is typically selected to obtain a suitable field of view, such as covering an area of ​​65mm × 53mm. To ensure stable image quality and reduce ambient light interference, a dedicated light source system, such as a shadowless ring light or strip light, needs to be configured around the camera to illuminate the tray area from an appropriate angle, making the panel edge features more prominent.

[0038] Control panel 9 includes a touchscreen display showing key equipment statuses such as current material receiving count, pallet inventory, motor operating status, and any fault alarms. The screen includes a clearly marked manual / automatic mode switch. In manual mode, individual function buttons allow maintenance personnel to individually control the three-axis robotic arm 2's return to zero and movement, the pallet storage mechanism 5's raising and lowering, and the pallet translation mechanism 8's left and right movements, primarily for equipment debugging, maintenance, and emergency handling. Key parameter settings, such as the quantity received per pallet and the lifting reference position, should be centralized in a parameter setting menu that requires access permissions (e.g., a password) to prevent accidental modification by operators. With this setup, control panel 9 becomes the core for commanding and monitoring the stable operation of the entire automated material receiving device.

[0039] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0040] In practical applications, before the device starts working, the operator needs to load empty LCD panel trays onto the tray storage mechanism 5 in the panel picking area. The lifting motor 504 of the tray storage mechanism 5 is activated, driving the threaded rod 505 to rotate, thereby raising the tray support 507 and tray support plate 509 connected by the threaded sleeve 508 until the top empty tray reaches the preset loading height of the three-axis robotic arm 2. At the same time, spare empty trays must also be pre-stored on the tray storage mechanism 5 in the tray storage area.

[0041] After entering the formal material receiving process, the three-axis robotic arm 2 accurately places the processed LCD panels retrieved from the upstream process onto the empty tray at the top of the tray storage mechanism 5 in the panel receiving area. The system continuously counts, and when it determines that the current tray is about to be full, it automatically triggers the tray replenishment program. At this time, the tray translation mechanism 8 begins to operate: its transverse motor 802 drives the gear 803 to rotate along the rack 12 in the transverse track 7, driving the entire tray translation mechanism 8 to move horizontally above the tray storage area. Subsequently, the electrically controlled suction cup 806 at the bottom of the L-shaped top plate 805 of the tray translation mechanism 8 is energized and picks up the empty tray at the top of the area.

[0042] The pallet translation mechanism 8 carries the empty pallet horizontally to directly above the panel picking area. The electric suction cup 806 is de-energized, releasing the empty pallet and placing it on top of the already full pallet stack below. After the action is completed, the pallet storage mechanism 5 in the panel picking area is immediately activated. Its lifting motor 504 drives the threaded rod 505 to rotate, causing the entire pallet support 507, carrying all pallets (including newly added empty pallets and the already full pallets below), to descend synchronously by a distance equal to the thickness of one pallet. This ensures that the newly added empty pallet can be accurately lowered to the fixed placement height of the three-axis robotic arm 2, thereby immediately starting a new round of material collection, achieving seamless connection of the material collection process.

[0043] Once the pallet storage mechanism 5 in the panel picking area has accumulated a certain number of fully loaded pallets, the operator can open the picking box door 10 and remove the entire stack of fully loaded pallets. The adjustable slot 807 and movable slot 808 designed on the L-shaped top plate 805 of the pallet translation mechanism 8 allow adjustment of the position of the electrically controlled suction cup 806, enabling the device to adapt to LCD panel pallets of different sizes and enhancing the equipment's versatility. The entire workflow, through this "placement-replenishment-descent" cycle principle, ensures highly efficient and uninterrupted automated material collection.

[0044] In summary, by utilizing the above-mentioned technical solution of this utility model, the automated material receiving process is achieved through the coordinated operation of the three-axis robotic arm 2, the pallet translation mechanism 8, and the pallet storage mechanism 5. When the pallets in the panel picking area are about to be full, the pallet translation mechanism 8 can automatically pick up empty pallets from the pallet storage area and accurately transfer and stack them on top of the full pallets. The pallet storage mechanism 5 in the panel picking area ensures that the top empty pallet is always accurately reset to the preset material placement position of the three-axis robotic arm 2, thereby achieving seamless connection of different pallet receiving operations. This allows the three-axis robotic arm 2 to operate continuously without waiting, eliminating production line interruptions caused by traditional manual pallet changing and greatly ensuring the continuous and stable operation of the high-speed LCD panel production line.

[0045] This invention effectively ensures the product quality of fragile LCD panels during the receiving process. The entire receiving process is completed by automated actuators such as the three-axis robotic arm 2, minimizing surface scratches, fingerprint contamination, or electrostatic damage that may be caused by direct contact between operators and the panels. At the same time, the tray storage mechanism 5 can effectively limit the placement of the LCD panel tray, preventing it from shifting or colliding during lifting or lateral movement. The tray translation mechanism 8 operates smoothly, ensuring the stability of the tray during the transfer process. Thus, the risk of the panels being scratched or broken during the receiving process is reduced from multiple aspects, which is conducive to improving the yield of the final product.

[0046] By automating the entire material receiving process, the manual input required for this station can be significantly reduced, directly lowering long-term labor and management costs, improving the versatility of the equipment, demonstrating significant flexible production capabilities when facing multi-variety, small-batch production tasks, reducing the equipment modification costs and time required for product changeovers, and improving the overall economic efficiency of the production line.
