AI Technical Summary
Existing processing equipment for LED display panel production has difficulty in accurately controlling the overall posture of the frame when clamping frame panels with different curvatures. This results in the stress points on the edge of the frame panel not being collinear with the center of gravity, causing the display panel and frame panel to be unable to be precisely aligned, thus affecting the assembly quality.
The positioning area consists of a positioning mechanism and a negative pressure tube. The vertical upward and downward movement of the negative pressure tube adjusts the posture of the frame plate, and the positioning plate guides and limits the position to ensure that the frame plate is in a horizontal state. For flexible display panels, a linear actuator and a negative pressure tube are used to adjust their curvature for precise installation. For rigid display panels, a negative pressure fan and a connector are used to cut the protective film.
This improved the installation accuracy and assembly quality of the display panel and frame, avoided repeated debugging, and reduced usage costs and mold requirements.

Description
Technical Field
[0001] This invention relates to the field of LED display panel processing technology, and more specifically, to a processing apparatus for producing LED display panels with adsorption function. Background Technology
[0002] An LED display panel is a display device that uses light-emitting diodes (LEDs) as its light source. Larger LED display panels are used in high-traffic areas to facilitate the display of public information. To enhance the display effect and attract attention by covering the viewer's field of vision from multiple angles, large LED display panels with curved designs can provide an immersive visual experience. These large, curved LED display panels are composed of multiple smaller, independent LED display panels. The smaller panels are easy to transport, and individual panels are easy to replace if they fail.
[0003] Large LED display panels with a curved design typically consist of an outer frame and multiple independent smaller LED display panels. These smaller LED display panels have a certain curvature, and are sequentially mounted on the outer frame. Each smaller LED display panel includes a frame and a display panel; the display panel is installed within the frame, which protects the electronic components on the back of the display panel. To prevent the display panel from loosening or falling off during use, and to facilitate maintenance and replacement, the display panel and frame are attached using magnetic attraction. Magnets are placed on the back of the display panel and inside the frame, and the display panel is mounted in the frame by mutual attraction. To ensure precise assembly of the display panel within the frame, mounting slots are created within the frame. The magnets on the display panel extending into the corresponding mounting slots indicate that the display panel is precisely mounted on the frame.
[0004] In the prior art, when assembling the display panel and the frame plate, in order to avoid damaging the display panel, a clamping mechanism is first used to clamp the edge of the frame plate, and then a material picking structure is used above the frame plate to vertically move the display panel from top to bottom, so that the display panel can be installed inside the frame plate.
[0005] However, due to different usage requirements, the sizes of large LED display panels with curved designs vary, and the curvature of small LED display panels also varies. When the clamping mechanism clamps frame panels with different curvatures, it is difficult to accurately control the overall posture of the frame panel. The force points on the edge of the frame panel and the center of gravity of the frame panel are not always collinear, causing the frame panel to tilt. The magnets on the display panel are not easy to accurately extend into the mounting slot by moving vertically downwards, resulting in a decrease in installation accuracy. The display panel and the frame panel cannot be accurately aligned, requiring repeated adjustments and affecting the overall assembly quality. Summary of the Invention
[0006] The present invention provides a processing device for producing LED display panels with adsorption function. The problem to be solved is that: in existing processing devices for producing LED display panels with adsorption function, when the clamping mechanism clamps frame plates with different curvatures, it is difficult to accurately control the overall posture of the frame plate. The force points on the edge of the frame plate and the center of mass of the frame plate are not always collinear, which leads to the tilting of the frame plate. It is inconvenient for the magnets on the display plate to be accurately inserted into the mounting groove by vertically moving downwards, resulting in a decrease in installation accuracy. The display plate and the frame plate cannot be accurately aligned, requiring repeated adjustments, which affects the overall assembly quality.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a processing device for producing LED display panels with adsorption function, comprising a support platform, a positioning mechanism provided on the support platform, the positioning mechanism comprising multiple positioning plates, the multiple positioning plates being inclinedly arranged on the positioning mechanism, a positioning area being formed between the multiple positioning plates, the opening of the positioning area gradually narrowing from top to bottom, a support seat being provided between corresponding two positioning plates, and a negative pressure tube being provided in the positioning area.
[0008] It also includes a material handling mechanism and a conveying mechanism. The material handling mechanism includes a robotic arm. The robotic arm's execution end is equipped with a linear driver. The linear driver has two negative pressure pipes. In use, the conveying mechanism conveys the frame plate and the display plate. The negative pressure pipes adsorb and clamp the display plate onto the support base. The negative pressure pipes lift the display plate from bottom to top by moving vertically upward to keep the display plate in a horizontal state. The negative pressure pipes then move vertically downward to make the display plate fall horizontally onto the support base.
[0009] In a preferred embodiment, the positioning mechanism further includes a linear driver four, which is fixedly disposed inside the support platform. A fixed seat is fixedly disposed on the output end of the linear driver four, and a negative pressure pipe three is fixedly disposed on the fixed seat. The negative pressure pipe three is slidably disposed with respect to the support platform.
[0010] In a preferred embodiment, the linear actuator includes a threaded rod and an auxiliary seat. The threaded rod is rotatably disposed within the auxiliary seat, and two movable seats are threadedly connected to the threaded rod. A negative pressure pipe is disposed on the movable seats, and the threaded rod is used to drive the two movable seats to move synchronously in opposite directions.
[0011] In a preferred embodiment, a linear actuator 2 is fixedly mounted on the movable base, and a negative pressure tube 1 is fixedly mounted on the output end of the linear actuator 2. The output end of the linear actuator 2 is used to drive the negative pressure tube 1 to move vertically.
[0012] In a preferred embodiment, a stabilizing base is fixedly mounted on the auxiliary base, a linear driver three is fixedly mounted on the stabilizing base, and a negative pressure tube two is fixedly mounted on the output end of the linear driver three. The negative pressure tube two is used to adsorb the middle part of the display panel.
[0013] In a preferred embodiment, the conveying mechanism is provided in two sets, which are respectively located on both sides of the robotic arm. One set of conveying mechanism is used to convey the frame plate, and the other set of conveying mechanism is used to convey the display plate.
[0014] In a preferred embodiment, the material handling mechanism further includes a linear driver 5, which is arranged along the length direction of the conveying mechanism, and the robotic arm is fixedly arranged with the output end of the linear driver 5.
[0015] In a preferred embodiment, the number of negative pressure pipes three is set to two, and the bottom ends of the two negative pressure pipes three are fixedly connected to the same auxiliary pipe, and a negative pressure fan is fixedly connected to the auxiliary pipe.
[0016] In a preferred embodiment, the bottom end of the negative pressure tube is fixedly connected to an adsorption seat, the bottom of the adsorption seat is fixedly provided with a flexible layer, and the bottom of the adsorption seat is also fixedly provided with a sealing layer, which is located inside the flexible layer.
[0017] In a preferred embodiment, a support plate is also provided on the support platform, a first connecting seat is fixedly provided on the support plate, a second connecting seat is also fixedly provided on the support plate, a limit plate is slidably provided on the support plate, the first connecting seat is used to place the flat frame, and negative pressure gas is generated inside the first connecting seat to adsorb the flat frame.
[0018] The beneficial effects of this invention are as follows:
[0019] 1. This invention, by setting up a positioning mechanism, consists of multiple positioning plates forming a positioning area. After the frame plate is moved into the positioning area, the posture of the frame plate is adjusted by the vertical upward movement of the negative pressure pipe three. During the posture adjustment process, the positioning plates guide and limit the frame plate, and the negative pressure formed in the negative pressure pipe three positions the frame plate, ensuring that the frame plate is in a horizontal state. It can adaptively adjust its posture according to the curvature of the frame plate, so that the frame plate is in a horizontal state. The magnet on the display plate can be accurately installed on the frame plate by vertical downward movement, which improves the installation accuracy, avoids repeated adjustments later, and improves the assembly quality.
[0020] 2. By setting up a linear actuator three and a negative pressure tube two, when pressing and assembling a flexible display panel, the display panel is attracted by the bottom end of the negative pressure tube one, and then the output end of the linear actuator three is activated. The bottom end of the negative pressure tube two pushes the middle part of the display panel, thereby bending and deforming the display panel. The curvature of the display panel is automatically adjusted and the display panel is assembled onto the frame plate, which further improves the accuracy of the pressing and assembly.

[0035] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0036] Refer to the instruction manual appendix Figures 1 to 5 , Figure 10 and Figure 11 A processing device for producing LED display panels with adsorption function includes a support platform 1, a positioning mechanism 3 is provided on the support platform 1, the positioning mechanism 3 includes multiple positioning plates 31, the multiple positioning plates 31 are all inclinedly arranged on the positioning mechanism 3, a positioning area is formed between the multiple positioning plates 31, the opening of the positioning area gradually narrows from top to bottom, a support seat 311 is provided between corresponding two positioning plates 31, and a negative pressure tube 32 is provided in the positioning area.
[0037] It also includes a material handling mechanism 2 and a conveying mechanism 4. The material handling mechanism 2 includes a robotic arm 21. The execution end of the robotic arm 21 is equipped with a linear driver 22. The linear driver 22 is equipped with two negative pressure pipes 23. In use, the conveying mechanism 4 conveys the frame plate 5 and the display plate 6. The negative pressure pipes 23 adsorb and clamp the display plate 6 onto the support base 311. The negative pressure pipes 32 lift the display plate 6 from bottom to top by moving vertically upward to keep the display plate 6 in a horizontal state. The negative pressure pipes 32 move vertically downward to make the display plate 6 fall horizontally onto the support base 311.
[0038] The positioning mechanism 3 also includes a linear actuator 33, which is fixedly installed inside the support platform 1. A fixed base is fixedly installed on the output end of the linear actuator 33, and a negative pressure pipe 32 is fixedly installed on the fixed base. The negative pressure pipe 32 is slidably installed with the support platform 1.
[0039] The linear actuator 22 includes a threaded rod and an auxiliary seat. The threaded rod is rotatably mounted inside the auxiliary seat, and two movable seats are threadedly connected to the threaded rod. A negative pressure pipe 23 is mounted on the movable seats. The threaded rod drives the two movable seats to move synchronously in opposite directions. A motor is fixedly mounted on the auxiliary seat, and the output shaft of the motor is fixedly mounted to the threaded rod. The rotation of the motor output shaft can adjust the synchronous counter-movement of the two movable seats, thereby adjusting the distance between the two movable seats.
[0040] Two sets of conveying mechanisms 4 are provided, one on each side of the robotic arm 21. One set of conveying mechanisms 4 is used to convey the frame plate 5, and the other set is used to convey the display plate 6. Each set of conveying mechanisms 4 includes two drive rollers, and the same conveyor belt is driven to the corresponding two drive rollers. Both conveyor belts are equipped with partition blocks to divide the conveyor belt into multiple storage spaces. These storage spaces are used to hold individual frame plates 5 and display plates 6. In other words, the partition blocks separate the frame plates 5 and display plates 6, ensuring that the frame plates 5 and display plates 6 are conveyed in a specific posture. This specific posture includes, but is not limited to, the frame plates 5 and display plates 6 being conveyed in a specific posture. Figure 10 The partitions are placed on the conveyor belt in a specific posture. The distance between two adjacent partitions is set according to the usage requirements. The partitions on the conveyor belt are used to separate the conveyor frame plate 5 and the display plate 6 in a specific posture. This is a mature existing technology and will not be described in detail here.
[0041] It should be noted that, referring to Figure 10 The frame plate 5 and the display panel 6 are installed together by magnetic adsorption. The frame plate 5 has an arc shape and a centrally symmetrical structure. Multiple magnetic posts (first type) are fixedly installed at the bottom of the display panel 6. Connecting posts are fixedly installed inside the frame plate 5, and mounting grooves are opened at the top of the connecting posts. Magnetic posts (second type) are fixedly installed in the mounting grooves. Magnetic posts (first type) and magnetic posts (second type) are installed together by magnetic adsorption after contact. Both magnetic posts (first type) and magnetic posts (second type) are made of neodymium iron boron permanent magnets, which are currently the most powerful permanent magnet materials. The state of multiple frame plates 5 assembled together is shown in the figure. Figure 11 To enhance the overall display effect of the large-sized LED display panel with its curved design, adjacent display panels 6 should be tightly fitted together to avoid black borders between adjacent display panels 6 that could disrupt the integrity of the large-sized LED display panel's display effect. Therefore, referring to... Figure 10 The bottom of the display panel 6 has a positioning groove that engages with the top of the frame plate 5, preventing black edges when two adjacent display panels 6 are assembled. The top of the frame plate 5 has an auxiliary groove, within which a second magnetic post is fixedly installed. A first magnetic post is also fixedly installed on the bottom edge of the display panel 6, engaging within the auxiliary groove. This auxiliary groove ensures a tight connection between the edge of the display panel 6 and the frame plate 5. The bottom of the frame plate 5 has a through hole through which the wiring harness used in the display panel 6 extends. Multiple LEDs are mounted on the surface of the display panel 6, each powered by a wiring harness. The power supply to the LEDs and the wiring harness connection are mature existing technologies and will not be elaborated upon further here.
[0042] It should also be noted that the linear actuator 33 is a cylinder, which is fixedly installed inside the support platform 1. The output end of the cylinder is fixedly connected to the negative pressure pipe 32. There are two negative pressure pipes 32, which are symmetrically arranged on both sides of the support base 311. The bottom ends of the two negative pressure pipes 32 are fixedly connected to the same auxiliary pipe, and a negative pressure fan is fixedly connected to the auxiliary pipe. A negative pressure fan is fixedly connected to the negative pressure pipe 23, which is used to extract the gas inside the negative pressure pipe 23. Suction cups are provided at the top end of the negative pressure pipe 32 and the bottom end of the negative pressure pipe 23, which are used to adsorb the frame plate 5 and the display plate 6. The robotic arm 21 is equipped with a recognition camera. The robotic arm 21 is programmed according to requirements and can stably and accurately drive its end effector to move in conjunction with the recognition camera. As a mature existing technology, this will not be described in detail here.
[0043] The specific implementation scenario is as follows: Both the frame plate 5 and the display plate 6 are placed on a conveyor belt. The conveyor belt moves the frame plate 5 and display plate 6. The end of the robotic arm 21, i.e., the execution end, drives the negative pressure pipe 23 to a vertical position and moves it above the frame plate 5 on the conveyor belt. Then, the negative pressure pipe 23 moves vertically downwards until its bottom end contacts the surface of the frame plate 5. The negative pressure fan is activated, drawing gas from the negative pressure pipe 23 to create a negative pressure. Under the action of the suction cup and the negative pressure, the frame plate 5 is positioned by the bottom end of the negative pressure pipe 23. Then, the execution end of the robotic arm 21 drives the negative pressure pipe 23 to move directly above the positioning area. Simultaneously, the negative pressure pipe 23 drives the frame plate 5 to move directly above the positioning area. Finally, the negative pressure pipe 23 moves downwards, causing the frame plate 5 to move to the positioning area. Within the positioning area, the frame plate 5 is brought into contact with the support base 311, and then the negative pressure in the negative pressure pipe 23 is released. Since the bottom of the frame plate 5 has a certain curvature, the frame plate 5 on the support base 311 is not necessarily in a horizontal position. The linear actuator 33 is activated, and the output end of the linear actuator 33 drives the two negative pressure pipes 32 to move vertically upward. As the negative pressure pipes 32 continue to move upward, the top of the negative pressure pipes 32 contacts the bottom of the frame plate 5. Since the tops of the two negative pressure pipes 32 are at the same height, when the tops of the negative pressure pipes 32 move upward, they first contact the inclined side of the bottom of the frame plate 5, that is, the angle of the frame plate 5 is adjusted within the positioning area. The inclined positioning plates 31 on both sides of the frame plate 5 can limit and guide the frame plate 5 when adjusting its angle. When the tops of both negative pressure pipes 32 are in contact with the bottom of the frame plate 5, the frame plate 5 is in a horizontal state. At this time, the frame plate 5 is above the support base 311 and does not contact the support base 311. Then, the negative pressure pipes 32 are driven to move vertically downward until the negative pressure pipe 23 contacts the inner wall of the top of the frame plate 5, so that the negative pressure pipe 23 applies downward pressure to the frame plate 5. With the guidance and limiting effect of the positioning plate 31, the top of the negative pressure pipe 32 is tightly attached to the bottom of the frame plate 5. The negative pressure fan is started, and the negative pressure fan draws the gas inside the negative pressure pipe 32 to generate negative pressure inside the negative pressure pipe 32. The negative pressure formed inside the negative pressure pipe 32 adsorbs and positions the frame plate 5. This ensures that the frame plate 5 is adsorbed and positioned by the negative pressure pipe 32. The frame plate 5 is in a horizontal position. Then, the negative pressure tube 23 moves upward to release the downward pressure on the frame plate 5. The output end of the linear actuator 33 drives the negative pressure tube 32 to move vertically downward. The top of the negative pressure tube 32 then drives the frame plate 5 to move vertically downward. As the frame plate 5 continues to move downward in the positioning area, the frame plate 5 contacts the support base 311, and the top of the negative pressure tube 32 always applies an adsorption force to the frame plate 5. Under the guidance of the inclined positioning plate 31, the frame plate 5 is in a horizontal position. Then, the execution end of the robotic arm 21 drives the negative pressure tube 23 to move above the conveyor belt of the display plate 6. The negative pressure tube 23 adsorbs the display plate 6 and transfers it to the top of the positioning area. Then, the negative pressure tube 23 is driven to move downward to press the display plate 6 onto the frame plate 5.
[0044] Compared with the existing technology, by setting up a positioning mechanism 3, multiple positioning plates 31 form a positioning area. After the frame plate 5 is moved into the positioning area, the posture of the frame plate 5 is adjusted by the vertical upward movement of the negative pressure pipe 32. During the posture adjustment process, the positioning plate 31 guides and limits the frame plate 5. With the negative pressure formed in the negative pressure pipe 32, the frame plate 5 is positioned, ensuring that the frame plate 5 is in a horizontal state. It can adaptively adjust its posture according to the curvature of the frame plate 5, so that the frame plate 5 is in a horizontal state. The magnet on the display plate 6 can be accurately installed on the frame plate 5 by vertical downward movement, which improves the installation accuracy, avoids repeated adjustments in the future, and improves the assembly quality.
[0045] Refer to the instruction manual appendix Figure 6 and Figure 7 Because large-size LED display panels have different curvatures depending on their application requirements, separate frame plates 5 and display panels 6 need to have matching curvatures. Display panels 6 with different curvatures often require new molds, leading to high usage and manufacturing costs. Therefore, display panels 6 are designed as flexible display panels. Flexible display panels 6 have high flexibility and bendability, enabling them to adapt to various complex installation environments and creative design needs. Therefore, using flexible display panels 6 can meet usage requirements and reduce costs. However, flexible display panels 6 are initially horizontal; only when... The flexible display panel 6 can only be bent after applying external force. When the flat flexible display panel 6 is assembled onto the frame plate 5, it cannot be guaranteed that the magnetic post 1 can accurately enter the auxiliary groove. In particular, in order to ensure that the display panel 6 can be tightly assembled onto the frame plate 5, the auxiliary grooves on both sides of the frame plate 5 have an inclined angle, which makes the pressing assembly of the frame plate 5 and the display panel 6 still not precise enough. To solve the above problems, specifically, a linear actuator 24 is fixedly installed on the moving base, and a negative pressure tube 23 is fixedly installed on the output end of the linear actuator 24. The output end of the linear actuator 24 is used to drive the negative pressure tube 23 to move vertically. A stabilizing base is fixedly installed on the auxiliary base, and a linear actuator 3 25 is fixedly installed on the stabilizing base. A negative pressure tube 26 is fixedly installed on the output end of the linear actuator 3 25. The negative pressure tube 26 is used to adsorb the middle of the display panel 6.
[0046] It should be noted that both linear actuator 24 and linear actuator 3 25 are cylinders. The structure of negative pressure tube 26 is the same as that of negative pressure tube 1 23. A suction nozzle is also provided at the bottom of negative pressure tube 26. The movement of the output end of linear actuator 24 can adjust the vertical movement of negative pressure tube 1 23, and the movement of the output end of linear actuator 3 25 can drive negative pressure tube 26 to move vertically.
[0047] It should also be noted that before the negative pressure tube 23 adsorbs and positions the flexible display panel 6, the two negative pressure tubes 23 are first driven to move away from each other. When both negative pressure tubes 23 are located at the top edge of the flexible display panel 6, the bottom end of the negative pressure tube 23 is driven to contact the top of the display panel 6. When a negative pressure is formed in the negative pressure tube 23, the adsorption of the flexible display panel 6 is completed. Then, the negative pressure tube 23 adsorbs the flexible display panel 6 and moves it to the top of the positioning area. At this time, the flexible display panel 6 is in a flat state. At this time, a horizontal frame plate 5 has been placed in the positioning area. The linear actuator 25 is started. The movement of the output end of the linear actuator 25 drives the negative pressure tube 26 to move vertically downward. Since the bottom ends of the two negative pressure tubes 23 have been positioned on both sides of the flexible display panel 6, the negative pressure tube 26 applies pressure to the middle of the display panel 6 when it moves vertically downward, thereby achieving the effect of bending the display panel 6. Then, the magnetic column 1 is inserted into the auxiliary groove. Of course, the above operation method is only one of many. Another operation method is that after the two negative pressure tubes 23 position the display panel 6, the output end of one of the two linear actuators 24 is moved upward, so that the display panel 6 is in a slightly tilted state. Then, the negative pressure tube 26 is activated to generate downward pressure on the middle of the display panel 6. This allows one side of the magnetic post 1 to enter the auxiliary slot first, and then the other side of the magnetic post 1 is installed into the corresponding auxiliary slot. The movement of the output end of the linear actuator 25 only needs to produce relative displacement with the movement of the output end of the linear actuator 24, and is not limited to whether the output ends of the linear actuator 25 and the negative pressure tube 26 move upward or downward. It is worth mentioning that since the large-size LED display panel with a curved design is composed of multiple display panels 6, the curvature of a single display panel 6 is small, including but not limited to 10° to 15°. Therefore, when adjusting the curvature of the display panel 6, the suction nozzles at the bottom of the negative pressure tubes 23 and 26 can always be in contact with the surface of the display panel 6 without loosening.
[0048] Refer to the instruction manual appendix Figure 1 and Figure 2 To facilitate the movement of the robotic arm 21, the material handling mechanism 2 specifically includes a linear driver 5, which is arranged along the length of the conveying mechanism 4, and the robotic arm 21 is fixedly arranged with the output end of the linear driver 5.
[0049] It should be noted that the robotic arm 21 is equipped with a linear motor, which is located between the two conveying mechanisms 4, and the output end of the linear motor is fixedly installed with the robotic arm 21.
[0050] Refer to the instruction manual appendix Figure 8 and Figure 9In order to improve the adsorption capacity of the end of the negative pressure tube 23 to the display panel 6 and to prevent the end of the negative pressure tube 23 from becoming loose when transferring the frame plate 5 and the display panel 6, specifically, the bottom end of the negative pressure tube 23 is fixedly connected to the adsorption seat 231, the bottom of the adsorption seat 231 is fixedly provided with a flexible layer 232, and the bottom of the adsorption seat 231 is also fixedly provided with a sealing layer 233, which is located inside the flexible layer 232.
[0051] It should be noted that the flexible layer 232 is made of synthetic fiber, while the sealing layer 233 is made of rubber. The flexible layer 232 has a relatively dense fiber structure, providing excellent adsorption performance. When in contact with the surfaces of the frame plate 5 and the display panel 6, the flexible layer 232 generates sufficient friction and adsorption force, and also acts as a buffer, reducing vibrations during movement. It can also adapt to surfaces with varying flatness, improving the reliability of adsorption. The sealing layer 233 is located inside the flexible layer 232, further enhancing the adsorption effect with the frame plate 5 and the display panel 6, and further optimizing its adaptation to the unevenness of the surfaces of the frame plate 5 and the display panel 6.
[0052] It should also be noted that the bottom end of the second negative pressure tube 26 and the top end of the third negative pressure tube 32 can also be equipped with an adsorption seat 231 for tightly adsorbing the positioning frame plate 5 and the display plate 6.
[0053] Unlike the above solutions, in addition to large-size LED display panels with curved designs, the application also includes large-size flat LED display panels. These flat large-size LED display panels are composed of multiple small-size flat display panels 6. Since the small-size flat display panels 6 do not require curvature, using rigid display panels 6 reduces operating costs. The rigid, flat display panels 6 also require a frame plate 5. To prevent scratches, dust accumulation, oxidation, and other problems during production, transportation, installation, and use, a protective film is applied to the surface of the display panels 6 during production. This protective film is larger than the area of the display panels 6. After the display panels 6 are assembled with the frame plate 5, the larger edges of the protective film are trimmed. For automatic trimming of the protective film after assembling the rigid, flat display panels 6, refer to the attached instruction manual. Figure 12 and Figure 13 Specifically, the support platform 1 is also provided with a support plate 71, a connecting seat 72 is fixedly provided on the support plate 71, a connecting seat 73 is also fixedly provided on the support plate 71, and a limit plate 74 is slidably provided on the support plate 71. The connecting seat 72 is used to place the flat frame 75, and negative pressure gas is generated inside the connecting seat 72 to adsorb the flat frame 75.
[0054] It should be noted that a negative pressure fan is fixedly connected to both connector 1 72 and connector 2 73. After the negative pressure pipe 1 23 transfers the flat frame 75 to connector 1 72, the display panel 6 is assembled onto the flat frame 75. Then, a negative pressure is generated inside connector 2 73. The suction end of connector 2 73 adsorbs the excess protective film on the display panel 6. Then, the protective film on the surface of the display panel 6 is cut. Since the scraps of the protective film have been adsorbed by connector 2 73, when the flat frame 75 with the display panel 6 installed is removed, the scraps of the protective film can be automatically separated from the display panel 6, thereby improving the operating efficiency.
