Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] The core of the present invention is to provide a device capable of automatically loading and unloading large liquid crystal display panels, achieving the purpose of reducing labor costs.

[0042] Please refer to Figures 1 - 5 , a large-size liquid crystal panel automatic loading and unloading device, including a frame 1, a workstation 6, a feeding mechanism 4, a loading and unloading mechanism 5, and a positioning mechanism 2. The workstation 6 is arranged on one side of the frame 1. The workstation 6 is used for performing process steps such as assembling, assembling, and detecting the liquid crystal panel. The feeding mechanism 4 is installed on the frame 1 and is used for transporting the box body 3 containing the liquid crystal panel. The empty box body 3 and the box body 3 containing the liquid crystal panel are placed on the feeding mechanism 4. The loading and unloading mechanism 5 includes a robot arm 501 for transporting the liquid crystal panel from the box body 3 to the workstation 6. That is to say, the liquid crystal panel in the box body 3 is sent to the workstation 6 through the robot arm 501. After the process is completed, the liquid crystal panel is sent back into the empty box body 3 through the robot arm 501, and the above steps are repeated, that is, the process of automatically loading and unloading the large-size liquid crystal panel is realized. The positioning mechanism 2 is installed on the frame 1 and is used for positioning the box body 3 containing the liquid crystal panel.

[0043] It should be noted that the specific structure of the feeding mechanism 4 is not limited in this embodiment. In some embodiments, the feeding mechanism 4 can adopt a plurality of parallel drums, which are connected by a chain or a belt and are synchronously moved by a motor.

[0044] In other embodiments, the feeding structure can adopt a conveyor belt structure to realize the feeding function.

[0045] In addition, the specific structure of the positioning mechanism 2 in this embodiment is not limited. In some embodiments, a lead screw can be used, and two clamping plates are arranged on the lead screw. The lead screw is driven by a motor to rotate to make the two clamping plates approach each other to complete the positioning function of the box body 3.

[0046] In other embodiments, a slide rail can be used, and two slidable clamping plates are arranged on the slide rail. The two clamping plates are driven by a cylinder or an electric cylinder to approach each other to complete the positioning function of the box body 3.

[0047] In addition, the loading and unloading mechanism 5 in this embodiment can use a robot to replace the robotic arm 501 to complete the loading and unloading of the liquid crystal panel.

[0048] During use, processes such as assembly, assembling, and inspection can be performed at the workstations 6 on the frame 1, not limited to the use of a single process. The feeding mechanism 4 is installed on the frame 1 to convey the box body 3 containing the liquid crystal panel. Empty box bodies 3 and box bodies 3 containing liquid crystal panels are placed on the feeding mechanism 4. The box body 3 containing the liquid crystal panel is conveyed to the loading position through the feeding structure, reducing manual participation. The positioning mechanism 2 is installed on the frame 1 and is used to position the box body 3 containing the liquid crystal panel, enabling the liquid crystal panel to be in a more accurate position, thereby avoiding the situation of dropping due to deviation in the grasping position during the process of grasping the liquid crystal panel. The loading and unloading mechanism 5 includes a robotic arm 501 for transporting the liquid crystal panel from the box body 3 to the workstation 6. That is to say, the liquid crystal panel in the box body 3 is sent to the workstation 6 through the robotic arm 501. After the process is completed, the liquid crystal panel is sent back into the empty box body 3 through the robotic arm 501. By repeating the above steps, the process of automatically loading and unloading large-sized liquid crystal panels is realized. The entire process replaces manual labor with machinery, reducing labor costs and labor intensity, achieving the purpose of reducing the production costs of the enterprise, while enhancing the safety during the process of handling large-sized liquid crystal panels, and greatly improving the automation degree of the production of large-sized liquid crystal panels.

[0049] Please refer to Figure 5 , in some embodiments, the feeding mechanism 4 includes at least two sets of roller structures 401. The two sets of roller structures 401 are respectively placed with empty box bodies 3 and box bodies 3 containing liquid crystal panels. That is to say, by setting at least two sets of roller structures 401, that is, each set is composed of multiple rollers arranged in parallel and distributed. The conveyance of the box body 3 is realized through this structure. At the same time, empty box bodies 3 and box bodies 3 containing liquid crystal panels are respectively placed on the roller structures 401. Since the liquid crystal panels are stacked inside the box body 3, after the corresponding processes are completed for the liquid crystal panels, they will be placed inside the empty box body 3.

[0050] It should be noted that the specific quantity of the drum structure 401 in this embodiment is not limited. It can be adjusted according to production needs. For example, multiple stations 6 are arranged on the frame 1, and the quantity of the drum structure 401 is increased to increase the corresponding quantity of the boxes 3, so as to improve work efficiency.

[0051] In some embodiments, at least two groups of the drum structures 401 are even numbers and are synchronously rotated through couplings. That is to say, in order to make the empty boxes 3 and the boxes 3 containing liquid crystal panels correspond to each other, the drum structures 401 are limited to even numbers, so as to keep the boxes 3 corresponding to each other and ensure the conversion of the liquid crystal panels between the boxes 3.

[0052] In some embodiments, the positioning mechanism 2 includes a first slide rail 201, a second slide rail 202, a first positioning baffle 203 and a second positioning baffle 204. The first slide rail 201 and the second slide rail 202 are installed on the frame 1, and the first slide rail 201 and the second slide rail 202 are installed in a cross shape. The first positioning baffle 203 is slidably installed on the first slide rail 201, and the second positioning baffle 204 is slidably installed on the second slide rail 202. When the feeding mechanism 4 transports the box 3 to contact with the first positioning baffle 203 and the second positioning baffle 204, the positioning of the box 3 is realized. That is to say, the first slide rail 201 and the second slide rail 202 are installed in a cross shape, and the box 3 can be effectively positioned through the first positioning baffle 203 and the second positioning baffle 204 thereon, because the angle between them is 90 degrees and an effective fitting state can be formed with the side wall of the box 3.

[0053] It should be noted that the sliding mode of the first positioning baffle 203 and the second positioning baffle 204 in this embodiment is not limited. In some embodiments, the positions of the first positioning baffle 203 and the second positioning baffle 204 can be manually adjusted, and a limiting mechanism is set to fix their positions, so as to realize their positioning function.

[0054] In other embodiments, the movement of the first positioning baffle 203 and the second positioning baffle 204 can be driven by a cylinder, an electric cylinder, a hydraulic cylinder or a motor, so as to realize their positioning function.

[0055] In addition, the specific structures of the first positioning baffle 203 and the second positioning baffle 204 in this embodiment are not limited. In some embodiments, they can adopt a plate-like structure, and a buffer layer made of rubber material is arranged on the contact surface with the box 3 to avoid damaging the box 3.

[0056] In order to further improve the positioning effect of the box body 3 and reduce the movement of the box body 3 during the process of picking and placing the liquid crystal panel, in some embodiments, the positioning mechanism 2 further includes a first slider 205, a first clamping baffle 207, a second slider 206 and a second clamping baffle 209. The first slider 205 is slidably mounted on the first slide rail 201. A first lifting cylinder is mounted on the first slider 205. A first clamping cylinder 210 is mounted on the extending end of the first lifting cylinder. The first clamping baffle 207 is mounted on the extending end of the first clamping cylinder 210. The second slider 206 is slidably mounted on the second slide rail 202. A positioning lifting cylinder 208 is mounted on the second slider 206. A second clamping cylinder 211 is mounted on the extending end of the positioning lifting cylinder 208. The second clamping baffle 209 is mounted on the extending end of the second clamping cylinder 211. When the feeding mechanism 4 transports the box body 3 to contact with the first positioning baffle 203 and the second positioning baffle 204, the first lifting cylinder, the positioning lifting cylinder 208, the first clamping cylinder 210 and the second clamping cylinder 211 act, and the first clamping baffle 207 and the second clamping baffle 209 are both in contact with the box body 3 to realize the clamping of the box body 3. That is to say, through the cooperation of the first positioning baffle 203 and the first clamping baffle 207, the clamping and positioning of the box body 3 in the X-axis direction are realized. Through the cooperation of the second positioning baffle 204 and the second clamping baffle 209, the clamping and positioning of the box body 3 in the Y-axis direction are realized. At the same time, with the cooperation of the first lifting cylinder and the positioning lifting cylinder 208, it is possible to avoid interfering with the feeding and discharging of the box body 3. Specifically, when the box body 3 is transported by the feeding mechanism 4, the first lifting cylinder and the positioning lifting cylinder 208 respectively drive the first clamping baffle 207 and the second clamping baffle 209 to move downward, leaving space for the movement of the box body 3.

[0057] In some embodiments, the positioning mechanism 2 further includes a plurality of positioning driving members for driving the first positioning baffle 203, the second positioning baffle 204, the first slider 205 and the second slider 206 to slide on the first slide rail 201 and the second slide rail 202.

[0058] It should be noted that the specific structure of the driving member is not limited in this embodiment. In some embodiments, the driving member can be a cylinder, a cylinder or a hydraulic cylinder.

[0059] In other embodiments, the driving member can be realized by a combination of a lead screw and a motor. The motor drives the lead screw to rotate, and two threads with opposite rotation directions are provided on the lead screw to realize the opposite movement of the first positioning baffle 203 and the second positioning baffle 204, or the opposite movement of the second slider 206 and the second positioning baffle 204.

[0060] In some embodiments, the loading and unloading mechanism 5 further includes a feeding slide rail 502 and a feeding driving member. The robotic arm 501 is slidably mounted on the feeding slide rail 502. That is to say, by extending the slide rail towards the working station 6, it is convenient for the robotic arm 501 to perform loading and unloading. The feeding driving member is mounted on the feeding slide rail 502 and is used to drive the robotic arm 501 to slide on the feeding slide rail 502.

[0061] It should be noted that the specific structure of the driving member is not limited in this embodiment. In some embodiments, the driving member can be a cylinder, an air cylinder or a hydraulic cylinder.

[0062] Please refer to Figure 2 , in some embodiments, a feeding lifting cylinder 503 is provided on the robotic arm 501. An installation frame 504 is installed at the extending end of the feeding lifting cylinder 503. A fixture 505 for grasping the liquid crystal display panel is provided on the installation frame 504. That is to say, by grasping the liquid crystal panel with the fixture 505 and driven by the lifting cylinder, the liquid crystal panel can be gently picked up and placed, which is beneficial to reducing the damage of the liquid crystal panel.

[0063] In some embodiments, the fixture 505 is a plurality of suction cups installed on the installation frame 504. That is to say, by adsorbing the surface of the liquid crystal panel with the suction cups, the grasping of the liquid crystal panel is achieved. At the same time, a gas source is provided on the installation frame 504 and is connected to the plurality of suction cups through a pipeline.

[0064] It should be noted that in this embodiment, a buffer portion is provided at the end of the suction cup. The buffer portion is composed of a corrugated pipe structure made of rubber, so as to increase the buffer force when grasping the liquid crystal panel, which is beneficial to further reducing the damage to the liquid crystal panel.

[0065] In some embodiments, telescopic frames 506 for adjusting the width are provided on both sides of the installation frame 504. Specifically, by means of the telescopic frames 506, the installation frame 504 has a way to adjust the width, so as to cope with the loading and unloading of liquid crystal panels of different sizes. For liquid crystal panels of different sizes, by adjusting the width, the grasping stability can be increased, and it is easier to stabilize the center of gravity of the liquid crystal panel.

[0066] That is to say, the key point of this embodiment is that: through the work station 6 on the rack 1, process steps such as assembly, disassembly, and detection can be carried out, not limited to the use of a single process. The feeding mechanism 4 is installed on the rack 1 to convey the box 3 containing the liquid crystal panel. The empty box 3 and the box 3 containing the liquid crystal panel are placed on the feeding mechanism 4. The box 3 containing the liquid crystal panel is conveyed to the loading position through the feeding structure, reducing the participation of manual labor. The positioning mechanism 2 is installed on the rack 1 to position the box 3 containing the liquid crystal panel, enabling the liquid crystal panel to be in a more accurate position, so as to avoid the situation of dropping caused by deviation of the grasping position during the process of grasping the liquid crystal panel. The loading and unloading mechanism 5 includes a robotic arm 501 for transporting the liquid crystal panel from the box 3 to the work station 6. That is to say, the liquid crystal panel in the box 3 is sent to the work station 6 through the robotic arm 501. After the process is completed, the liquid crystal panel is sent back into the empty box 3 through the robotic arm 501. By repeating the above steps, the process of automatically loading and unloading large-sized liquid crystal panels is realized. The whole process replaces manual labor with machinery, reducing labor costs and labor intensity, achieving the purpose of reducing the production cost of the enterprise. At the same time, the safety of transporting large-sized liquid crystal panels is improved, and the automation degree of large-sized liquid crystal panel production is greatly enhanced.
