Description

Technical Field

[0001] This invention relates to the field of liquid crystal display module manufacturing technology, specifically, to a liquid crystal display module manufacturing equipment and method for light-free backlight and FOG assembly. Background Technology

[0002] TFT (Thin-Film Transistor) liquid crystal display modules are assembled from a backlight and a FOG (Flexible Open Source Group). The backlight is the core light source component of the TFT liquid crystal display module, acting as an optical conversion device that transforms side light into surface light. It integrates LEDs, a light guide plate, film materials, a frame, and driving circuitry. To improve process efficiency and reduce manufacturing costs, the backlight LEDs are integrated into the flexible circuitry of the FOG. This design saves on driving circuitry and increases backlight manufacturing efficiency, and is widely used in small-size liquid crystal modules.

[0003] However, because FOG's flexible circuits integrate LEDs, the assembly process of the LCD module cannot be automated. Current technology primarily relies on manual assembly, leading to the following problems:

[0004] (1) The assembly efficiency is low, the labor input is large, and the production cost remains high;

[0005] (2) Improper assembly can easily cause misalignment between the LED and the backlight slot, affecting the product yield.

[0006] (3) Poor display effect, easy to produce defects such as uneven display, dark corners, insufficient brightness, light leakage, etc., which seriously affect product quality and market competitiveness.

[0007] To address these technical problems, this invention proposes an automated assembly scheme to improve process efficiency and product quality. Summary of the Invention

[0008] To address the issues of low efficiency and non-standard assembly leading to low brightness, dark corners, lamp holes, light leakage, and uneven display in TFT-type backlightless liquid crystal display modules, this invention provides a liquid crystal display module manufacturing equipment and method for assembling backlights and FOGs without light sources. This automates the assembly of backlights and FOGs in TFT-type backlightless liquid crystal display modules, improves the assembly effect, and achieves a more reliable and stable display effect.

[0009] The present invention solves the above problems through the following technical solution:

[0010] A liquid crystal display module manufacturing equipment for backlight and FOG assembly without light source includes: an FOG feeding device for receiving FOG components from the previous process, conveying the FOG components, removing protective films, and correcting their positions before transporting them to the FOG loading station of the FOG feeding device; an FOG loading device for picking up FOG components from the FOG loading station and transferring them to an FOG loading platform, where the FOG loading platform fixes the FOG components by vacuum adsorption; a backlight loading device for picking up backlight components from a backlight temporary storage platform and transferring them to the backlight loading platform, where the backlight loading platform fixes the backlight components by vacuum adsorption; and a backlight fixing, correction, and film removal device, comprising a backlight loading platform, a backlight fixing mechanism, a backlight correction mechanism, and a release film separation mechanism, wherein the backlight fixing mechanism adsorbs and fixes the backlight components onto the backlight loading platform, the backlight correction mechanism performs coordinate correction on the backlight components, and the release film separation mechanism removes the release film from the backlight components; top-view vision. The alignment and bonding device is used to acquire the LED slot positions of the backlight assembly and the LED positions of the FOG assembly, and output alignment coordinates to drive the corresponding backlight loading platform to perform position fine-tuning; so that the LEDs of the FPCA in the FOG assembly are installed into the LED slots of the backlight assembly, and the FPCA of the FOG assembly is bonded to the frame adhesive of the backlight assembly to form an adhesive assembly composed of the backlight assembly and the FOG assembly; the turnover device is used to transfer the bonded assembly from the backlight loading platform to the fourth platform assembly device; the fourth platform assembly device includes a fourth platform and a flipping platform, the fourth platform is used to receive and adsorb the backlight assembly in the adhesive assembly, the flipping platform is used to receive and adsorb the FOG assembly in the adhesive assembly, and the flipping platform flips the FOG assembly so that the LCD of the FOG assembly is installed into the LCD slot of the backlight assembly to form a modular product; the output turnover device is used to transfer the modular product from the fourth platform to the output conveyor belt device.

[0011] Furthermore, the present invention also solves the above problems through the following technical solutions:

[0012] A method for manufacturing a liquid crystal display module with a light-free backlight and FOG assembly includes the following steps:

[0013] S1, FOG component feeding: The FOG component that follows the previous bonding process is conveyed by the first conveyor belt. The protective film on the FOG component is automatically removed by the roll tape. The FOG component feeding and positioning block corrects the FOG component to a 90° direction. The conveying stops after the FOG component with the protective film removed is in place by the sensing fiber optic.

[0014] S2, FOG component loading: The robotic arm picks up the FOG components after the film is torn off and transfers them to the FOG loading platform, where they are fixed by vacuum adsorption;

[0015] S3. Backlight loading: The backlight loading robot arm picks up the backlight component from the backlight temporary storage area, rotates it 90° by a high-precision rotary cylinder, and then transfers it to the pre-assembled first backlight loading platform or second backlight loading platform, where it is fixed by vacuum adsorption.

[0016] S4. Backlight fixing, correction and film removal: The horizontal micro cylinder and the vertical micro cylinder drive the backlight X-axis correction block and the backlight Y-axis correction block to tighten inward, and perform coordinate correction on the backlight assembly on the backlight loading platform; the pneumatic V-clamp clamps the backlight tearing hand position of the backlight assembly, and the small servo motor drives the rotating arm to rotate upward 90° to separate the release film from the backlight.

[0017] S5. Visual alignment and bonding: The pre-assembled first backlight loading platform or the second backlight loading platform moves to the bottom of the top visual alignment and bonding device. The visual alignment camera collects the position of the LED light slot of the backlight and the position of the LED of the FOG component and outputs the alignment coordinates. The corresponding backlight loading platform makes a slight adjustment to its position according to the alignment coordinates and then moves upward gently so that the LED of the FOG component is installed in the LED light slot of the backlight component. The frame adhesive of the backlight component is bonded to the FPCA of the FOG component.

[0018] S6. Turnover and transfer: The turnover robotic arm picks up the adhesive components after bonding and transfers them to the fourth platform and the flipping platform. The fourth platform adsorbs and fixes the backlight component in the adhesive components, and the flipping platform adsorbs and fixes the FOG component in the adhesive components.

[0019] S7. Backlight and FOG component correction: The left, right and vertical micro cylinders of the fourth platform drive the corresponding backlight mechanical correction blocks to perform coordinate correction on the backlight components; the left, right and vertical micro cylinders of the flip platform drive the corresponding LCD mechanical correction blocks to perform coordinate correction on the FOG components.

[0020] S8. Flipping Assembly: The first small servo asynchronous motor drives the flipping platform to flip 180° towards the fourth platform, so that the LCD of the FOG component is inserted into the LCD slot of the backlight component to form a modular product.

[0021] S9. Output step: The robotic arm picks up the module product and transfers it to the output conveyor belt for output.

[0022] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0023] (1) This invention achieves fully automated, unmanned operation from FOG component feeding, film removal, alignment, and loading, to backlight component loading, fixing, correction, and film removal, to visual alignment, bonding, turnover, flipping assembly, and output through the coordinated operation of the FOG feeding device, FOG loading device, backlight loading device, backlight fixing, correction, film removal, top visual alignment, bonding, turnover, flipping assembly, and output. The various devices are controlled and coordinated by PLC to form a complete automated production line, which fundamentally solves the problems of low efficiency and high labor input in the existing technology of manual assembly, greatly improves process efficiency, and reduces production costs.

[0024] (2) This invention utilizes a top-mounted visual alignment and bonding device. A visual alignment camera captures the positions of the LED slots in the backlight assembly and the LEDs in the FOG assembly, generating alignment coordinates. This coordinates are then used to drive a servo asynchronous motor to achieve micron-level precision alignment between the front and rear positions. After alignment, a precision slide cylinder II drives the cylinder slider to move upwards slightly, precisely inserting the LEDs of the FOG assembly's FPCA into the LED slots of the backlight assembly. The frame adhesive around the backlight assembly automatically bonds to the FPCA of the FOG assembly. Visual alignment combined with servo closed-loop control effectively avoids deviations caused by manual alignment, ensuring alignment accuracy and bonding consistency.

[0025] (3) The present invention uses a first backlight feeding platform and a second backlight feeding platform arranged side by side and working alternately. When one backlight feeding platform performs visual alignment and bonding, the other backlight feeding platform simultaneously performs backlight feeding, fixing, correction and film peeling operations. The alternating and staggered working mode of the two platforms greatly improves the utilization rate of the equipment.

[0026] (4) This invention incorporates automatic correction mechanisms in several key stages: After the backlight is loaded, the backlight assembly is coordinate-corrected using a 90° inverted L-shaped structure formed by the backlight X-axis correction block and the backlight Y-axis correction block; on the fourth platform and the flipping platform, the corresponding backlight mechanical correction block and LCD mechanical correction block are driven by three sets of micro cylinders (left / right / vertical) to independently and accurately correct the coordinates of the backlight assembly and the FOG assembly. The multi-level correction mechanism ensures the positional accuracy of the backlight assembly and the FOG assembly throughout the assembly process, effectively preventing assembly defects caused by positional deviations. By using a pneumatic V-clamp to clamp the tearing hand position of the backlight assembly, and cooperating with a small servo motor to drive the rotating arm to flip upwards by 90°, the automatic removal of the release film from the backlight assembly is achieved. Compared to manual film removal, the automatic film removal method avoids contamination and damage that may be caused by human contact with the backlight assembly, improving product yield.

[0027] (5) The present invention uses the first small servo asynchronous motor of the fourth platform assembly device to drive the flipping platform to flip in the direction of the fourth platform, so as to accurately install the LCD of the FOG component into the LCD slot of the backlight component to form a modular product, effectively avoiding problems such as FPC distortion and alignment deviation caused by manual bending assembly.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1:

[0051] See attached document Figure 1-20 A liquid crystal display module manufacturing equipment for backlight and FOG assembly without light source includes an FOG feeding device, an FOG loading device, a backlight loading device, a backlight fixing, correction and film peeling device, a top visual alignment and bonding device, a turnover device, a fourth platform assembly device, an output turnover device and an output conveyor belt device.

[0052] The FOG feeding device is used to receive the FOG components from the previous process, and to transport the FOG components to the FOG loading station after removing the protective film and correcting their position. The FOG loading device is used to pick up the FOG components from the FOG loading station and transfer them to the FOG loading platform. The FOG loading platform fixes the FOG components by vacuum adsorption.

[0053] A backlight loading device is used to pick up the backlight components on the backlight temporary storage platform and transfer them to the backlight loading platform. The backlight loading platform fixes the backlight components by vacuum adsorption.

[0054] The backlight fixing, correction and film-removing device is equipped with a backlight feeding platform, a backlight fixing mechanism, a backlight correction mechanism and a release film separation mechanism. The backlight fixing mechanism is used to adsorb and fix the backlight component on the backlight feeding platform. The backlight correction mechanism is used to perform coordinate correction on the backlight component. The release film separation mechanism is used to remove the release film from the backlight component.

[0055] The top-mounted visual alignment and bonding device is used to collect the position of the LED slot of the backlight assembly and the LED position of the FOG assembly, and output alignment coordinates to drive the corresponding backlight loading platform to make fine-tuning of the position; so that the LED of the FPCA in the FOG assembly is installed into the LED slot of the backlight assembly, and the FPCA of the FOG assembly is bonded to the frame adhesive of the backlight assembly to form an adhesive assembly composed of the backlight assembly and the FOG assembly.

[0056] A transfer device is used to transfer the bonded components, after they have been bonded, from the backlight feeding platform to the fourth platform assembly device;

[0057] The fourth platform assembly device includes a fourth platform and a flipping platform. The fourth platform is used to receive and adsorb the backlight component in the fixed adhesive assembly. The flipping platform is used to receive and adsorb the FOG component in the fixed adhesive assembly. By flipping the FOG component, the LCD of the FOG component is installed into the LCD slot of the backlight component to form a modular product.

[0058] An output turnover device is used to transfer the modular finished product from the fourth platform to the output conveyor belt device.

[0059] In one specific embodiment, the specific structure of the preparation device is as follows:

[0060] 1. FOG feeding device;

[0061] like Figure 1 and Figure 2As shown, the FOG feeding device adopts a ring conveyor belt design, which is connected to the bonding process to feed the FOG. It consists of a conveyor belt 17, synchronous pulleys 28, synchronous belt 29, synchronous motor 30, roll adhesive tape, recycling reel, film-peeling tape fixing plate 24, guide rollers 25, recycling motor, FOG component feeding and positioning block 27, miniature cylinder, and sensing fiber optic cable 26. The synchronous motor is controlled by the PLC to rotate clockwise, and drives the conveyor belt to rotate clockwise through the synchronous belt and synchronous pulley. The FOG component moves smoothly from left to right as the conveyor belt rotates. The roll adhesive tape is installed on the film-peeling tape fixing plate. The tape is pulled out and horizontally wound around the two guide rollers below to another guide roller, and then connected to the recycling reel shaft. The tape is pulled out by the recycling motor driving the recycling reel to rotate counterclockwise. The first two guide rollers are installed on spring-loaded fixing rods and are equipped with downward pressure and rebound. When the tape adheres to the FOG protective film, the tape automatically separates the FOG protective film as the FOG moves. Simultaneously, the recycling reel drives the receiving tray to collect the waste protective film, preparing it for the next FOG to have its protective film removed. A micro-cylinder, controlled by a PLC-driven pneumatic valve, uses air pressure to push the piston rod of the micro-cylinder to extend and retract. The piston, connected to the FOG assembly's feeding correction block, extends and retracts synchronously, causing the FOGs to be positioned unevenly after the protective film is removed. The FOG is then pushed forward by the extended FOG feeding correction block, sliding along its edge to a 90° vertical position, achieving uniform correction so that the FOG enters the sensing area of ​​the sensing fiber at a 90° angle. The sensing fiber is mounted on its bracket and fixed to one end of the synchronous pulley of the conveyor belt. When the FOG reaches the sensing area of ​​the sensing fiber, the FOG blocks the fiber, and the fiber sensor outputs a command that causes the PLC to control the synchronous motor to stop rotating, completing the FOG feeding process.

[0062] Specifically, the FOG feeding device includes a first conveyor belt transport assembly, a film-tearing tape assembly, and a first FOG position correction assembly. The first conveyor belt transport assembly includes: a first conveyor belt 1701, a first synchronous pulley 2801, a second synchronous pulley 2802, a first synchronous belt 2901, a first synchronous motor 3001, and a drive shaft 66, which includes a first drive shaft 6601 and a second drive shaft 6602. Driven clockwise by the first synchronous motor, the first conveyor belt transports the FOG assembly placed above it from left to right. The film-tearing tape assembly is located above the first conveyor belt and includes a take-up tray 2301, a roll tape 2401, and a recycling reel. The device includes a shaft 23, a film-tearable tape fixing disc 24, a guide roller 25, a third guide roller 2503, a recycling motor, and a spring-loaded fixing rod 31 including a first spring-loaded fixing rod 3101 and a second spring-loaded fixing rod 3102. The guide roller 25 includes a first guide roller 2501 and a second guide roller 2502. After the tape is pulled out from the film-tearable tape fixing disc, it passes through the first guide roller, the second guide roller, and the third guide roller and winds around to the recycling reel shaft. The tape adheres to the protective film on the FOG assembly below the horizontally arranged first guide roller and second guide roller, and the protective film is separated from the surface of the FOG assembly as the recycling reel shaft rotates. The first FOG position correction component includes a sensing fiber optic cable 26, an FOG component feeding and correction block 27, and a first micro cylinder 3805. The FOG component feeding and correction block is located above the right end of the first conveyor belt. The first micro cylinder extends and retracts to drive the FOG component feeding and correction block to push the FOG component after film removal to a 90° vertical direction and then move left and right. The sensing fiber optic cable is located above the right end of the first conveyor belt and is used to sense when the FOG component is in position, indicating that it has reached the FOG loading station and to send a stop signal.

[0063] The FOG feeding device consists of three zones: upper, middle, and lower. The upper zone is equipped with film-removing tape for separating the protective film of the FOG components, the middle zone is used to install the first conveyor belt, and the lower zone is used to install the first synchronous motor of the synchronous motor 30.

[0064] (1) The first conveyor belt 1701 of the FOG feeding device is annularly mounted on the outside of the first drive shaft 6601 and the second drive shaft 6602 of the FOG feeding device bracket. The synchronous pulley 28 includes a first synchronous pulley 2801 and a second synchronous pulley 2802. One of the second synchronous pulleys 2802 is inserted on the outside of the first drive shaft 6601 at the right end. The first synchronous motor 3001 is fixed below the outside of the first conveyor belt 1701. One of the first synchronous pulleys 2801 is inserted on the shaft of the first synchronous motor 3001. The first synchronous belt 2901 is sleeved on the outside of the first synchronous pulley 2801 and the second synchronous pulley 2802. The first conveyor belt 1701 can be driven to rotate clockwise by driving the first synchronous motor 3001 to rotate clockwise.

[0065] Working principle: The first synchronous motor 3001 drives the first synchronous pulley 2801, the first synchronous belt 2901, and the second synchronous pulley 2802 to rotate clockwise. In turn, the rotation of the second synchronous pulley 2802 drives the first drive shaft 6601, the first conveyor belt 1701, and the second drive shaft 6602 to rotate clockwise synchronously.

[0066] An FOG component 47 is placed on the left side above the first conveyor belt 1701. When the first conveyor belt 1701 rotates clockwise, the FOG component 47 placed on the first conveyor belt 1701 moves to the right side as the first conveyor belt 1701 rotates, that is, it moves towards the direction close to the first drive shaft 6601, realizing the automated feeding and conveying of the FOG component.

[0067] (2) The recovery reel shaft 23 of the FOG feeding device is connected to the shaft of the recovery motor located above the upper section of the FOG feeding device support. The film-tear tape fixing plate 24 is installed below the upper section of the FOG feeding device support and can rotate freely. The first spring-loaded fixing rod 3101 and the second spring-loaded fixing rod 3102 are installed below the film-tear tape fixing plate 24 and are installed in a staggered manner with the film-tear tape fixing plate 24. The first guide roller 2501 is connected and installed to the first spring-loaded fixing rod 3101, and the second guide roller 2502 is connected and installed to the second spring-loaded fixing rod 3102. The first guide roller 2501 and the second guide roller 2502 are horizontally arranged above the downward-sloping roll of adhesive tape 2401 pulled out by the film-tearing tape fixing disc 24. The first spring-loaded fixing rod 3101 and the second spring-loaded fixing rod 3102 can rebound upward under the upward pressure of the first guide roller 2501 and the second guide roller 2502, respectively. The third guide roller 2503 is horizontally installed on the right side of the film-tearing tape fixing disc 24 and can rotate freely. One end of the roll tape 2401 is fixed to the film-tear tape fixing plate 24. After the roll tape 2401 is pulled out, it is horizontally wound around the first guide roller 2501 and the second guide roller 2502 below the film-tear tape fixing plate 24, and then wound upward from the left side of the third guide roller 2503, and connected to the recycling reel shaft 23. The tape is driven by the recycling motor to rotate the recycling reel shaft 23 counterclockwise, which pulls the roll tape 2401 out.

[0068] Operating principle: The FOG assembly 47 is placed on the first conveyor belt 1701 and moves to the right. The roll of adhesive tape 2401 is adhered to the FOG assembly 47 by the downward pressure of the first guide roller 2501 and the second guide roller 2502. The roll of adhesive tape 2401 is pulled counterclockwise by the recycling motor driving the recycling reel shaft 23, and is wound upward around the second guide roller 2502, so that the protective film on the FOG assembly is automatically separated. At the same time, the take-up tray 2301 is installed on the recycling reel shaft 23, and the take-up tray 2301 is driven to collect the separated protective film, preparing it for the next FOG assembly to have its protective film removed.

[0069] (3) The first micro cylinder 3805 of the FOG feeding device is fixed to the outside of the first conveyor belt 1701, near one end of the second synchronous pulley 2802. The piston rod of the first micro cylinder 3805 is connected to the FOG component feeding alignment block 27, and the FOG component feeding alignment block 27 moves in extension and retraction with the piston rod of the first micro cylinder 3805. The sensing fiber 26 is installed above the first conveyor belt 1701 near one end of the second synchronous pulley 2802 through a fixed structure, and does not contact the first conveyor belt 1701. It is used to sense the position and direction of the FOG component 47 so as to control the first synchronous motor 3001.

[0070] Operating Principle: After the protective film is removed from the FOG components, their positions are inconsistent. FOG components 47 continue to move to the right with the first conveyor belt 1701. Pushed backward by the extended FOG component feeding and alignment block 27, the FOG components 47 slide along the edge of the FOG component feeding and alignment block 27 to a 90° vertical direction before moving left and right, thus uniformly correcting the FOG components 47 to a 90° vertical position within the sensing area of ​​the sensing fiber 26. Once the FOG components reach the sensing area of ​​the sensing fiber 26, they block the fiber. The fiber optic sensor outputs a command that causes the PLC to control the first synchronous motor 3001 to stop rotating, completing the FOG component feeding. Through the FOG feeding device, automatic conveying of FOG components from the previous process, automatic removal of the protective film, and automatic position correction are achieved. This solves the problems of low efficiency and potential damage to FOG components from manual film removal. Simultaneously, the FOG component feeding and alignment block uniformly corrects the FOG components to a 90° direction, providing a positional reference for subsequent precise alignment and assembly, effectively improving assembly accuracy and efficiency.

[0071] II. FOG feeding device;

[0072] like Figure 1 and Figure 6 , Figure 9As shown, the FOG feeding device is located on the front and right sides of the FOG feeding device. The FOG feeding device comprises a FOG feeding platform 19, a servo asynchronous motor 1, a lead screw, a precision slide cylinder II 12, a robotic arm, a vacuum nozzle, a slide rail 55, and a slide groove 56. The servo asynchronous motor, controlled by the PLC, drives the lead screw to rotate forward and backward. The precision slide cylinder II moves left and right as the lead screw rotates forward and backward. The valve of the precision slide cylinder II, controlled by the PLC, is pressurized to move its piston rod up and down. The robotic arm is connected to the cylinder slider of the precision slide cylinder II. The robotic arm is equipped with a suction nozzle, a vacuum passage, and a quick-connect air hose. The suction nozzle is installed in the vacuum passage, and the valve is controlled by the PLC to achieve a vacuum suction effect. The robotic arm moves up and down and left and right with the cylinder slider. When the robotic arm moves to the infrared sensing area of ​​the FOG feeding conveyor belt, under the continuous control of the PLC, the robotic arm moves downward until the suction nozzle contacts the FOG surface. The suction nozzle draws a vacuum and sucks up the FOG. After the robotic arm moves upward with the cylinder slider of precision slide cylinder II, it moves to the right until it reaches the FOG loading platform. The FPC with LEDs on the FOG faces forward, and about 1 / 4 of the LCD protrudes from the FOG loading platform. Figure 6 As shown, the robotic arm moves downward with the cylinder slider of the precision slide cylinder II until the FOG contacts the FOG loading platform. At the same time, the FOG is fixed by the vacuum suction effect of the FOG loading platform, preparing for assembly.

[0073] Specifically, the FOG feeding device consists of components such as the FOG feeding platform 19, the servo asynchronous motor 1, the first threaded screw 401, the first precision slide cylinder II 1201, the robotic arm 65, and the first vacuum nozzle 6001.

[0074] (1) The servo asynchronous motor 1 of the FOG feeding device is a first servo asynchronous motor 101 fixed to the working platform. Its shaft is connected to a first threaded screw 401. The first threaded screw 401 can be driven by the first servo asynchronous motor 101 to achieve forward and reverse rotation. The FOG feeding platform 19 is fixed to the working platform and is located to the right of the first conveyor belt 1701.

[0075] (2) The first precision slide cylinder II 1201 of the FOG feeding device includes a first cylinder slider 5301, a first cylinder piston rod 5401 of a cylinder piston rod 54, a first slide rail 5501, and a first slide table; wherein, the first cylinder slider 5301 is slidably mounted on one side of the first slide rail 5501, and the first cylinder piston rod 5401 is provided between the first cylinder slider 5301 and the first slide rail 5501 away from the sliding mounting position, so as to drive the first cylinder slider 5301 to the first slide table via the first cylinder piston rod 5401. The slide rail 5501 slides on the slide rail 5501; the first cylinder slider 5301, the first cylinder piston rod 5401, and the first slide rail 5501 are a cylinder assembly. The cylinder assembly is set on the first slide table. The first slide table has an arc-shaped notch, and the first slide table has two slide grooves 56 to avoid the arc-shaped notch, namely the first slide groove 5601 and the second slide groove 5602. The first precision slide cylinder II 1201 is slidably installed on the slide rail of the work platform through the first slide groove 5601 and the second slide groove 5602, and is threadedly connected to the first threaded screw 401 through the arc-shaped notch.

[0076] (3) The robotic arm assembly of the FOG feeding device is connected to the first precision slide cylinder II 1201; specifically, the robotic arm assembly includes a robotic arm 65 and a first vacuum nozzle 6001 of the suction nozzle 60; a first vacuum channel 3601 is formed inside the robotic arm 65, one end of the robotic arm 65 is installed on the outside of the first cylinder slider 5301 of the first precision slide cylinder II 1201 by fixing bolts, the other end of the robotic arm 65 is connected to the first vacuum nozzle 6001, and the first vacuum nozzle 6001 communicates with one end of the first vacuum channel 3601. The other end of the robotic arm 65, that is, the back of the first precision slide cylinder II 1201, is provided with a connection hole of the first vacuum channel 3601. The connection hole is used to connect with the first air pipe quick connector 3701, which can realize the vacuum suction function.

[0077] Working principle: The first servo asynchronous motor 101 drives the first threaded screw 401 to rotate in both directions. The thread of the first threaded screw 401 drives the first precision slide cylinder II 1201 to move left and right. The robotic arm 65 moves left and right in sync with the movement of the first precision slide cylinder II 1201. The extension and retraction of the piston rod 5401 of the first cylinder drives the robotic arm 65 to move up and down. When the first servo asynchronous motor 101, connected to the first threaded screw 401, reverses, it drives the first precision slide cylinder II 1201, connected to the robotic arm 65, to move to the left to the limit position of the fiber optic sensing area. This drives the first cylinder piston rod 5401 of the first precision slide cylinder II 1201, which in turn moves the first cylinder slider 5301, connected to the robotic arm 65, downwards to the limit position. The first vacuum nozzle 6001, connected to the robotic arm 65, then contacts the FOG assembly with its protective film removed from the first conveyor belt 1701 of the FOG feeding device. The first vacuum nozzle 6001 then vacuum-suctions the FOG assembly with its protective film removed. Next, the first cylinder piston rod 5401 of the first precision slide cylinder II 1201, connected to the first cylinder slider 5301 and the robotic arm 65, moves upwards to the limit position. Then, the first servo asynchronous motor 101, connected to the first threaded screw 401, rotates forward, driving the first precision slide cylinder II 1201... Cylinder II 1201, connected to the robotic arm 65, moves to the right to the limit position of the FOG component loading area on the FOG loading platform 19. Then, it drives the first cylinder piston rod 5401 of the first precision slide cylinder II 1201 to move the first cylinder slider 5301 connected to the robotic arm 65 downward to the limit position, until the FOG component contacts the FOG loading platform 19. The first vacuum nozzle 6001 releases air, and the FOG component with the protective film torn off is vacuumed and fixed by the FOG loading platform 19. Subsequently, it drives the first cylinder piston rod 5401 of the first precision slide cylinder II 1201 to move the first cylinder slider 5301 connected to the robotic arm 65 upward to the limit position. The first servo asynchronous motor 101, connected to the first threaded screw 401, reverses, driving the first precision slide cylinder II 1201 connected to the robotic arm 65 to move to the left to the limit position of the fiber optic sensing area. The FOG feeding device enables automatic pick-up and precise transfer of FOG components after film removal. The vacuum adsorption fixation method ensures the positional stability of the FOG components during subsequent assembly, avoiding contamination and damage caused by manual handling, and improving feeding efficiency and positioning accuracy.

[0078] III. Backlight feeding device;

[0079] like Figure 1 and Figure 7 , Figure 8 , Figure 10 , Figure 13As shown, the operating platform includes a backlight storage area, a blister packaging recycling area, and a mechanical operation area. The mechanical operation area comprises a servo asynchronous motor 1, a precision slide cylinder 1, a threaded screw 4, a backlight loading robotic arm 3, a vacuum nozzle, a high-precision rotary cylinder, a small servo asynchronous motor, and a synchronous belt. The backlight storage area holds the backlight components, which are arranged in a uniform array on the blister packaging tray, such as... Figure 7 , Figure 8As shown, the blister packs are stacked sequentially on the backlight storage platform. As the backlight of each blister pack is fed, the robotic arm picks up the empty blister pack and moves it to the storage area. The PLC controls the shrink cylinder to raise the shrink piston cylinder, causing the backlight storage platform to rise as each backlight-equipped blister pack is used. The blister recycling area is used to hold empty blister packs. When the backlight is used up and the blister pack is empty, the robotic arm picks up the empty blister pack and moves it to the storage area. The PLC controls the shrink cylinder to shrink the piston cylinder, causing the recycling platform in the recycling area to lower. The mechanical operation area is used for loading backlight components and moving used blister packs to the recycling area. A servo asynchronous motor, controlled by the PLC, drives the screw to rotate forward and backward. The precision slide cylinder I, rotating with the screw, moves left and right. The precision slide cylinder I, controlled by the PLC, is also pressure-driven, causing the piston rod to move up and down. The backlit loading robotic arm is mounted on the cylinder slider of precision slide cylinder I. Precision slide cylinder I, controlled by a servo asynchronous motor and a PLC-controlled air valve, enables left-right and up-down movement. A small servo asynchronous motor is positioned near precision slide cylinder I on the backlit loading robotic arm, connected to a synchronous belt that drives a suction nozzle slide with gears at the other end. Driven by the PLC, the small servo asynchronous motor moves the slide back and forth. A high-precision rotary cylinder is mounted on the slide, and the cylinder's rotating platform has a quick-connect air hose. The suction nozzle is also located on this platform. The high-precision rotary cylinder, controlled by the PLC-controlled air valve, drives the cylinder's rotating platform to rotate 90° in both directions. The quick-connect air hose connects to the PLC's air valve control terminal, and the suction nozzle is activated by the air valve's opening and closing to perform vacuum suction. Under continuous PLC control, the robotic arm moves left-right and up and down, while the suction nozzle, along with the suction nozzle slide and rotating platform, performs back-and-forth movement, 90° rotation, and vacuum suction. Driven by the backlight loading robotic arm, high-precision rotary cylinder, precision slide cylinder I, and servo asynchronous motor, the nozzle moves to the backlight position in the backlight temporary storage area. The backlight loading robotic arm moves downward until the nozzle contacts the backlight, and the nozzle vacuum-holds the backlight component. The backlight loading robotic arm then moves upward to the safety limit. The high-precision rotary cylinder drives the rotating platform to rotate the backlight so that the LED light opening faces forward. The precision slide cylinder I drives the backlight loading robotic arm to move to the right to the backlight loading platform. After the backlight contacts the platform, the backlight loading platform evacuates and sucks in air to fix the backlight. Then, the nozzle releases air, and the backlight loading robotic arm completes the backlight loading process and moves to the backlight temporary storage area, thus completing the backlight loading.

[0080] Specifically, the backlight feeding device comprises a backlight temporary storage platform 5, a blister packing and recycling platform 10, a limit rod 52, a second servo asynchronous motor 102, a first precision slide cylinder I2, a second threaded screw 402, a backlight feeding robotic arm 3, a suction nozzle slide 9, a high-precision rotary cylinder 58, a second small servo asynchronous motor 1502 (acting as a small servo asynchronous motor 15), a second synchronous belt 2902, a gear 57, a second vacuum suction nozzle 6002, and a lifting mechanism, among other components. The backlight temporary storage platform is used to stack and place blister packs 51 containing backlight components. The blister packing and recycling platform is used to stack and place empty blister packs after use. The lifting mechanism is located below the backlight temporary storage platform and the blister packing and recycling platform, and is used to automatically compensate for the height difference caused by changes in the number of blister packs by raising and lowering the backlight temporary storage platform and / or the blister packing and recycling platform. The backlight loading robotic arm mechanism includes a first precision slide cylinder I, a second servo asynchronous motor, a second threaded screw, a backlight loading robotic arm, and a second vacuum nozzle. The second servo asynchronous motor drives the second threaded screw to rotate, which in turn drives the first precision slide cylinder I, which is mounted on the work platform, to slide on the work platform. This causes the first precision slide cylinder I to move left and right along the second threaded screw, and simultaneously drives the backlight loading robotic arm to move left and right. The extension and retraction of the piston rod of the second cylinder of the first precision slide cylinder I drives the backlight loading robotic arm to move up and down. The second vacuum nozzle is connected to the backlight loading robotic arm mechanism and is used to pick up the backlight components and empty blister trays from the backlight temporary storage platform. The backlight direction is adjusted by rotating 90°, and the backlight components are transferred to the backlight loading platform to complete the loading. The empty blister trays are also transferred to the blister recycling platform.

[0081] (1) The backlight temporary storage area and the blister packaging recycling area of ​​the backlight feeding device are respectively installed below the working platform, and the backlight temporary storage platform 5 and the blister packaging recycling platform 10 are respectively provided with limit rods 52 around their perimeters, such as Figure 7 , 8 As shown, the backlight temporary storage platform 5, used to limit the blister packaging of the two platforms, is installed on the left side of the base 64, and the blister packaging recycling platform is installed on the right side of the base 64. A lifting mechanism is provided between the backlight temporary storage platform 5 and the blister packaging recycling platform 10 and the base 64, respectively. The lifting mechanism includes a retractable cylinder 63, a retractable piston cylinder 62, and a quick-connect air hose 37. The base 64 is fitted with a retractable cylinder 63, which is connected to the retractable piston cylinder 62 and the quick-connect air hose 37. The retractable piston cylinder 62 is positioned between the base 64 and the backlight temporary storage platform 5 and the blister packaging recycling platform 10, and is used to lift the backlight temporary storage platform 5 and the blister packaging recycling platform 10 to achieve a lifting function, automatically compensating for height differences caused by changes in the number of blister packaging trays, and ensuring that the material handling position of the robotic arm remains constant.

[0082] Working principle: The backlight temporary storage platform 5 holds a blister tray containing the backlight assembly, such as... Figure 7 Left and Figure 8 As shown, the backlight of each blister pack is activated after material feeding. The backlit loading robot arm 3 is connected to the second vacuum nozzle 6002. By drawing a vacuum, it can pick up empty blister packs. The left-right and up-down movements of the backlit loading robot arm 3 pick up the empty blister packs and move them to the backlit temporary storage area. Figure 7 and Figure 8 As shown. The retraction cylinder 63 controls the retraction piston cylinder 62 to extend, lifting the backlight temporary storage platform 5 to a higher position. Conversely, the backlight temporary storage area is controlled by the retraction cylinder 63 to retract the retraction piston cylinder 62, lifting the backlight temporary storage platform 5 to a lower position.

[0083] (2) In the embodiment of the backlight feeding device, the rotating shaft of the second servo asynchronous motor 102 of the backlight feeding robotic arm mechanism is connected to the second threaded screw 402 and installed on the working platform. The second servo asynchronous motor 102 drives the second threaded screw 402 to rotate forward and backward. (See the corresponding side view of the robotic arm.) Figure 10 Side view. The first precision slide cylinder I2 is mounted on the second threaded screw 402 and can move horizontally left and right on the second threaded screw 402 by rotating the second threaded screw 402. The first precision slide cylinder I2 is slidably connected to the backlit feeding robot arm 3 and can drive the backlit feeding robot arm 3 to move up and down. The structure and specific principle of the first precision slide cylinder I2 are the same as those of the first precision slide cylinder II.

[0084] The first precision slide cylinder I2 includes: a cylinder assembly consisting of a second cylinder slider 5302, a second cylinder piston rod 5402, and a second slide rail 5502; and a second slide. The second slide has two slide grooves and an arc-shaped notch. The two slide grooves are a third slide groove 5603 and a fourth slide groove 5604, respectively. The cylinder assembly and the second slide are an integral structure. The third slide groove 5603 and the fourth slide groove 5604 of the second slide are respectively inserted into the slide rail of the work platform and are threadedly connected to the second threaded screw 402 through the arc-shaped notch.

[0085] Working principle: The piston rod 5402 of the second cylinder drives the first precision slide cylinder I2 to extend and retract, which pushes the second cylinder slider 5302 to move on the second slide rail 5502, and drives the backlit feeding robot arm 3 to move up and down.

[0086] (3) The backlight feeding robot arm 3 in the working area of ​​the backlight feeding device. In this embodiment, the backlight feeding robot arm 3 and the robot arm 65 have certain structural differences. The backlight feeding robot arm 3 is connected to the second vacuum nozzle 6002. Specifically, the backlit loading robotic arm 3 includes a second small servo asynchronous motor 1502, a third synchronous pulley 2803, a fourth synchronous pulley 2804, a second synchronous belt 2902, a fixed gear 57, a high-precision rotary cylinder 58, an inlet / outlet quick connector 59, a rotating platform 61, a second air pipe quick connector 3702, a suction nozzle slide 9, and a third slide rail 5503. The backlit loading robotic arm 3 is fixed on the second cylinder slider 5302. The fixed end of the backlit loading robotic arm 3 is equipped with the second small servo asynchronous motor 1502. The fourth synchronous pulley 2804 is installed on the shaft of the second small servo asynchronous motor 1502. The other end of the backlit loading robotic arm 3 is equipped with the third synchronous pulley 2803. The third synchronous pulley 2803 and the fourth synchronous pulley 2804 are together fitted with the second synchronous belt 2902.

[0087] The backlit loading robotic arm 3 is equipped with a third slide rail 5503, and the suction nozzle slide 9 is synchronously equipped with several suction nozzle grooves. The suction nozzle groove inserts slide into the third slide rail 5503 of the backlit loading robotic arm 3 to stabilize the suction nozzle slide 9. The suction nozzle slide 9 is equipped with a fixed gear 57, which fits into the second synchronous belt 2902 and can move back and forth within the second synchronous belt 2902 as the second synchronous belt 2902 rotates. A high-precision rotary cylinder 58 is installed on the suction nozzle slide 9 of the backlit loading robotic arm 3. A second vacuum suction nozzle 6002 is installed on the rotating platform 61 of the high-precision rotary cylinder 58. The rotating platform 61 is also equipped with a second air pipe quick connector 3702 to connect to the suction nozzle. The inlet and outlet air pipe quick connectors 59 of the high-precision rotary cylinder 58 are connected to the control end air valve, and the second air pipe quick connector 3702 connects the suction nozzle to the control end air valve.

[0088] Operating principle: The second small servo asynchronous motor 1502 on the backlit loading robotic arm 3 rotates forward and backward, and the second synchronous belt 2902 rotates in a circular motion. Since the fixed gear 57 inside the suction nozzle slide 9 is wound inside the synchronous belt 29, the internal teeth of the second synchronous belt 2902 drive the suction nozzle slide 9 to slide back and forth with the third slide rail 5503 of the backlit loading robotic arm 3. The air inlet and outlet are controlled by the air valve switch at the control end, driving the rotating platform 61 of the high-precision rotary cylinder 58 to rotate 90° in both directions. At the same time, the air valve switch controls the second air pipe quick connector 3702 to connect to the suction nozzle for vacuum suction, and the second vacuum suction nozzle 6002 connected to the suction nozzle slide 9 realizes the vacuum suction function.

[0089] Backlight feeding device linkage operation instructions:

[0090] When the second servo asynchronous motor 102 drives the second threaded screw 402 to rotate forward, it drives the backlight loading robot arm 3 to move to the left along with the first precision slide cylinder I2 until the coordinate limit of the backlight temporary storage area is above the backlight temporary storage platform; the second small servo asynchronous motor 1502 drives the second synchronous belt 2902 to rotate in a circular motion, driving the suction nozzle slide 9 to move forward to above the backlight temporary storage platform; the second cylinder piston rod 5402 of the first precision slide cylinder I2 is driven to extend and retract, pushing the backlight loading robot arm 3 to move downward along with the second cylinder slider 5302 until the second vacuum suction nozzle contacts the backlight 50 on the backlight temporary storage platform, controlling the second vacuum suction nozzle to evacuate and pick up the backlight assembly; the second cylinder piston rod 5402 of the first precision slide cylinder I2 is driven to extend and retract, pushing the backlight loading robot arm 3 to move upward along with the second cylinder slider 5302 to the limit; the second servo asynchronous motor 102 drives the second threaded screw 402 to rotate forward, pushing the backlight loading robot arm 3 to move upward along with the second cylinder slider 5302 to the limit; the second servo asynchronous motor 102 drives the second threaded screw 402 to rotate forward, pushing the second threaded screw 402 to rotate upward along with the second cylinder slider 5302 to the limit; the second servo asynchronous motor 102 drives the second threaded screw 402 to rotate forward, driving ...

[0091] After the backlight loading is completed, the piston rod 5402 of the second cylinder of the first precision slide cylinder I2 is extended and retracted, pushing the backlight loading robot arm 3 to move upward to the limit along with the slider 5302 of the second cylinder; the second servo asynchronous motor 102 drives the second threaded screw 402 to rotate forward, driving the backlight loading robot arm 3 to move to the left along with the first precision slide cylinder I2 to the backlight temporary storage area, i.e., the backlight temporary storage platform 5, to wait.

The precision slide cylinder II is driven to move up and down by the pressure of the air valve controlled by the PLC. The pressure of the air valve controlled by the PLC drives the horizontal and vertical micro cylinders, pushing the micro cylinder movable rods to move back and forth. The backlight Y-axis correction block is connected to the vertical micro cylinder, and the backlight X-axis correction block is connected to the horizontal micro cylinder. The backlight X / Y axis correction blocks achieve the function of tightening inward or expanding outward by the extension and retraction of the micro cylinder movable rods. The backlight X / Y axis correction blocks are used to tighten inward to the limit to push the coordinate correction of the backlight components of the backlight loading platform. A small servo motor, controlled by a PLC, rotates upwards by 90°. A rotating arm connected to the servo motor's shaft rotates upwards by 90°. The pneumatic V-clamp of the rotating arm connects to a vacuum passage, and the quick-connect air hose, under the pressure of a PLC-controlled air valve, drives the pneumatic V-clamp to clamp the backlight release film tearing handle of the first backlight feeding platform. As the rotating arm rotates upwards by 90°, the backlight release film is separated. The second backlight feeding platform, as...

Vacuum suction holes 39 and vacuum channels 36 are provided on the backlight loading platform as the backlight fixing mechanism.

[0095] (1) The left servo asynchronous motor 104 and the right servo asynchronous motor 105 are respectively installed on the work platform. The rotating shafts of the left servo asynchronous motor 104 and the right servo asynchronous motor 105 are respectively connected to the left threaded screw 405 and the right threaded screw 406.

The working platform on the rear side of the backlight loading platform 602 has a piston rod of a horizontal micro cylinder 3801 connected to a backlight X-axis correction block 34, and a piston rod of a vertical micro cylinder 3802 connected to a backlight Y-axis correction block 35. The backlight X-axis correction block 34 and the backlight Y-axis correction block 35 form a 90° inverted L-shape and are located above the first or second backlight loading platform 601 at a suitable position. The quick-connect air hoses of the backlight X-axis correction block 34 and the backlight Y-axis correction block 35 are connected to a control valve switch. Figure 3 As shown.

[0102] Working principle: Drive the control valve switch of the pre-assembled first backlight loading platform 601 and second backlight loading platform 602 to push the piston rod of the horizontal micro cylinder 3801 and the vertical micro cylinder 3802 to extend and retract, and simultaneously push the backlight X-axis correction block 34 and the backlight Y-axis correction block 35 to tighten inward or expand outward, so as to correct the coordinate of the backlight assembly of the first backlight loading platform 601 or the second backlight loading platform 602 in the appropriate position.

[0103] (5) The pre-assembled first backlight feeding platform and second backlight feeding platform, i.e., the backlight fixing correction and film tearing device, are also equipped with a small servo motor 7, a rotating shaft arm 32, a pneumatic V-clamp 33, and a third air pipe quick connector 3703 as a release film separation mechanism; the small servo motor 7 is installed on the working platform, the rotating shaft of the small servo motor 7 is connected to the rotating shaft arm 32, the rotating shaft arm 32 is provided with a second vacuum channel 3602, the second vacuum channel 3602 is connected to the pneumatic V-clamp 33 and the third air pipe quick connector 3703 respectively, and the third air pipe quick connector 3703 is connected to the control end air valve switch, such as Figure 3 As shown.

[0104] Working principle: The control valve of the backlight fixing, correction and film tearing device is switched on and off. The air pressure drives the pneumatic V-clamp 33 to clamp the tearing hand position of the backlight assembly on the first backlight loading platform 601 and the second backlight loading platform 602. Then, the small servo motor 7 drives the rotating shaft arm 32 to rotate 90° clockwise upwards, separating the release film of the backlight assembly from the backlight.

[0105] The backlight fixing, correction, and release film removal device enables precise positioning of the backlight assembly and automatic removal of the release film before assembly. Vacuum adsorption fixation ensures that the backlight assembly does not shift during correction and release film removal; the X / Y axis bidirectional correction mechanism achieves precise coordinate positioning of the backlight assembly, providing a foundation for the subsequent micron-level alignment of the LED light slot and LED; the pneumatic V-clamp, combined with the 90° rotation of the rotating arm, achieves automated separation of the release film, avoiding contamination or damage to the backlight assembly that may be caused by manual release film removal. The dual-platform alternating interactive working mode significantly improves equipment utilization and shortens production cycle time.

[0106] V. Top visual alignment and fitting device;

[0107] like Figure 1 and 4 As shown, the top visual alignment and bonding device 22 is fixedly installed above the work platform, located in the installation area of ​​the second backlight loading platform 602 and the FOG loading platform 19, as shown. Figure 1 As shown, the top visual alignment and bonding device 22 has a hole in the middle for fixing the visual alignment camera 40, as shown. Figure 4 As shown.

[0108] Working principle: The visual alignment camera 40 of the top visual alignment and bonding device 22 captures the positions of the LED light slot of the backlight and the LED 49 of the FPCA48, and generates alignment coordinate output. This drives the left servo asynchronous motor 104 or the right servo asynchronous motor 105 to slightly reverse forward and backward to correct the alignment coordinates of the backlight. After visual alignment by the first backlight loading platform 601 or the second backlight loading platform 602, the cylinder slider is driven by the left precision slide cylinder II 1202 or the right precision slide cylinder II 1203 to make a secondary upward floating motion, such as... Figure 16 As shown in Figure a, the LEDs of the FPCA48 of the FOG component are installed into the LED slots of the backlight component. The adhesive around the backlight component automatically adheres to the FPCA of the FOG component, as shown in Figure a. Figure 16 b and Figure 17 As shown.

[0109] The top-mounted visual alignment and bonding device achieves micron-level high-precision visual alignment between the backlight component's LED light slot and the FOG component's LED, avoiding deviations caused by manual alignment. The visual alignment camera, combined with closed-loop control of the servo motor, ensures precise installation of the LEDs into the LED light slot, effectively guaranteeing the bonding accuracy and consistency between the frame adhesive and FPCA, fundamentally solving quality issues such as uneven display, dark corners, and light leakage caused by alignment deviations.

[0111] like Figure 1 and Figure 12 As shown, the turnover device comprises a servo asynchronous motor, a lead screw, a precision slide cylinder III, a turnover robotic arm, front / rear suction nozzles, and quick-connect air hoses. The servo asynchronous motor, controlled by a PLC, drives the lead screw to rotate forward and backward, causing the precision slide cylinder III to move left and right. The precision slide cylinder III, controlled by a PLC air valve switch, is pressure-driven, causing the cylinder piston rod to extend and retract, pushing the cylinder slider up and down. The turnover robotic arm, fixed to the cylinder slider, moves up and down synchronously. The quick-connect air hoses connect to a PLC air valve control switch, which, under PLC air valve control, connects the vacuum passage and the front / rear suction nozzles, enabling synchronous vacuum suction of the backlight and FOG. Under continuous PLC control, the assembly turnover device drives the servo asynchronous motor to rotate in reverse, causing the precision slide cylinder III to move the turnover robotic arm to the left, to the position of the third platform and either the first or second platform. The precision slide cylinder III then controls the cylinder slider to move the turnover robotic arm downward, until the front / rear suction nozzles simultaneously contact the backlight and FOG. The front / rear suction nozzles create a vacuum to extract the backlight and FOG components. Cylinder III controls the cylinder slider, which in turn moves the robotic arm upwards to its limit. This drives the servo asynchronous motor to rotate forward, causing the precision slide cylinder III to move the robotic arm to the right, to the fourth platform position. Cylinder III then controls the cylinder slider, which in turn moves the robotic arm downwards until the FOG and backlight assembly contact the fourth platform and the flip platform. The fourth platform and the flip platform then create a vacuum to secure the FOG and backlight components. Figure 14 As shown, the automated turnover of FOG and backlight assembly is completed (the backlight is placed on the fourth platform, and the FOG-LCD is rotated by flipping the platform).

[0112] Specifically, the turnover device includes components such as the third servo asynchronous motor 103, the third threaded screw 403, the precision slide cylinder Ⅲ21, the turnover robotic arm 20, the third vacuum nozzle 6003, the fourth vacuum nozzle 6004, and the third air pipe quick connector 3703.

Synchronously, the precision slide cylinder III 21 includes a fourth cylinder slider 5304, a fourth cylinder piston rod 5404, a fourth slide rail 5504 and a fourth slide table; wherein, the fourth cylinder slider 5304 is slidably installed on one side of the fourth slide rail 5504, and a fourth cylinder is provided between the fourth cylinder slider 5304 and the fourth slide rail 5504 away from the sliding installation position. The piston rod 5404 drives the fourth cylinder slider 5304 to slide on the fourth slide rail 5504 via the fourth cylinder piston rod 5404. The fourth cylinder slider 5304, the fourth cylinder piston rod 5404, and the fourth slide rail 5504 form a cylinder assembly. The cylinder assembly is mounted on the fourth slide platform. The fourth slide platform has an arc-shaped notch, and the fourth slide platform has a seventh slide groove 5607 and an eighth slide groove 5608 to avoid the arc-shaped notch. The precision slide cylinder III21 is slidably mounted on the slide rail of the work platform through the seventh slide groove 5607 and the eighth slide groove 5608, and is threadedly connected to the third threaded screw 403 through the arc-shaped notch.

[0115] (2) The precision slide cylinder III 21 of the turnover device is connected to the turnover mechanical arm 20; the turnover mechanical arm 20 is fixed on the fourth cylinder slider 5304.

[0116] Working principle: The fourth cylinder slider 5304 of the precision slide cylinder Ⅲ21 of the drive turnover device moves in an extension and retraction motion, and the piston rod 5404 of the fourth cylinder pushes the fourth cylinder slider 5304 to drive the turnover robot arm 20 to move up and down.

[0117] (3) The turnover robot arm 20 of the turnover device is provided with a third vacuum passage 3603. The third vacuum passage 3603 is connected to a fourth air pipe quick connector 3704 through the air passage hole at one end of the precision slide cylinder III 21. The fourth air pipe quick connector 3704 is connected to the air valve switch at the control end. The other end of the third vacuum passage 3603 is connected to two suction nozzles, namely the third vacuum suction nozzle 6003 and the fourth vacuum suction nozzle 6004. The third vacuum suction nozzle 6003 and the fourth vacuum suction nozzle 6004 are arranged in a front and rear position of the turnover robot arm 20, such as Figure 12 As shown.

[0118] Working principle: The third vacuum nozzle 6003 and the fourth vacuum nozzle 6004 of the drive turnover device are controlled by the air valve switch of the control end to vacuum suction, so that the third vacuum nozzle 6003 and the fourth vacuum nozzle 6004 of the turnover robot arm 20 can achieve vacuum suction, which is used to pick up the adhesive components of the backlight component and the FOG component respectively.

[0119] The transfer device enables the synchronous pickup and overall transfer of the backlight and FOG bonding components after bonding. The front and rear dual-nozzle layout ensures that the relative positions of the backlight and FOG components remain unchanged during the transfer process, avoiding secondary positioning errors. The precise drive of the precision slide cylinder III ensures the consistency of the transfer position.

After the fourth platform and tilting platform are connected to the backlight and FOG assembly, the backlight is placed on the fourth platform, and the FOG-LCD is rotated on the tilting platform. The PLC controls the air valve switch, creating a vacuum under air pressure to evacuate the fourth platform and tilting platform, thus fixing the backlight and FOG assembly. The three sets of micro cylinders on the left, right, and vertical sides of the fourth platform are controlled by PLC valve switches. Driven by air pressure, the piston rods of these cylinders extend and retract. The three sets of backlight mechanical correction blocks are fixed to the piston rods of these cylinders, enabling them to contract inwards or expand outwards, thus providing mechanical correction for the backlight components of the fourth platform. Similarly, the three sets of micro cylinders on the left, right, and vertical sides of the flip platform are also controlled by PLC valve switches. Driven by air pressure, the piston rods of these cylinders extend and retract. The three sets of LCD mechanical correction blocks are fixed to the piston rods of these cylinders, enabling them to contract inwards or expand outwards, thus providing mechanical correction for the FOG-LCD components of the flip platform. A small asynchronous motor, controlled by a PLC, rotates in both directions, driving the connecting rod shaft to rotate in both directions. The flipping platform is fixed to the connecting rod shaft, achieving a 180° backward rotation. Under the continuous control of the PLC, the fourth platform assembly, after connecting to the backlight and FOG components, immediately performs vacuum suction, using the vacuum suction holes of the fourth and flipping platforms to fix the backlight and FOG components. The three sets of micro cylinders on the left and right longitudinal directions of the fourth platform, controlled by the PLC's valve switches, drive the three sets of backlight mechanical correction blocks on the left and right longitudinal directions of the fourth platform to retract inward to their limit, and then expand outward to correct the backlight coordinates. The three sets of micro cylinders on the left and right longitudinal directions of the flipping platform, controlled by the PLC's valve switches, drive the three sets of LCD mechanical correction blocks on the left and right longitudinal directions of the flipping platform to retract inward to their limit, and then expand outward to correct the FOG-LCD coordinates.

[0127] (4) The flipping platform 16 of the fourth platform assembly device is provided with a third vacuum suction hole 3903. The vacuum channel inside the flipping platform 16 connects the third vacuum suction hole 3903 with the quick connector of the air pipe at the bottom.

The shaft of the first small servo asynchronous motor 1501 is connected to the connecting rod shaft 14. Both ends of the connecting rod shaft 14 are fixed with brackets. The flipping platform 16 is connected to the connecting rod shaft 14.

[0131] Function Description: The first small servo asynchronous motor 1501 driving the fourth platform assembly device drives the connecting rod shaft 14 to rotate forward and backward, thereby causing the flipping platform 16 to flip 180° towards the fourth platform direction. This achieves a 180° upward flip of the LCD of the FOG component on the flipping platform 16, assembling the LCD of the FOG component and embedding it into the LCD slot of the backlight component to form a modular product. The operation process of the flipping platform 16 is as follows: Figure 14 , Figure 16 c in Figure 18 As shown.

[0132] The fourth platform assembly device enables fully automated installation of the FOG component's LCD into the backlight component's LCD slot. The fourth platform and the flipping platform independently attach and fix the backlight component and FOG component, respectively, and use their respective mechanical correction blocks for precise coordinate correction, ensuring the relative positional accuracy of the two components during the flipping assembly process. The 180° flipping assembly method is simple in structure and reliable in operation, effectively avoiding problems such as FPC distortion and alignment deviations caused by manual bending assembly.

The quick-connect air hose is controlled by the PLC's pneumatic valve switch; under pneumatic pressure, it performs vacuum suction, connecting to the suction nozzle to achieve the vacuum suction function. Under the continuous control of the PLC, the output turnover device drives the servo motor, connected to the lead screw, to rotate in reverse, driving the precision slide cylinder II to move to the left to the platform's limit position 4. The precision slide cylinder II, controlled by the PLC's pneumatic valve switch, pushes the cylinder slider, connected to the robotic arm, downward until the suction nozzle contacts the module. The suction nozzle, controlled by a PLC-controlled pneumatic valve, creates a vacuum and draws in the module. Precision slide cylinder II, also controlled by a PLC-controlled pneumatic valve, moves the cylinder slider connected to the robotic arm to its limit position. A servo motor connected to a lead screw rotates forward, causing precision slide cylinder II to move to the right to the output conveyor belt limit position. Precision slide cylinder II, again controlled by a PLC-controlled pneumatic valve, moves the cylinder slider connected to the robotic arm downwards. The suction nozzle, controlled by a PLC-controlled pneumatic valve, releases air, separating the module from the nozzle and allowing it to fall onto the output conveyor belt.

[0135] Specifically, such as Figure 1 , Figure 9 As shown, the output turnover device consists of components such as servo motor 8, fourth precision slide cylinder II 1204, fourth threaded screw 404, robotic arm 65, and first air pipe quick connector 3701.

[0142] Operational instructions for the output turnover device: The servo motor 8 of the output turnover device, connected to the fourth threaded screw 404, reverses, driving the fourth precision slide cylinder II 1204 to move to the left to the fourth platform limit. Driving the fourth precision slide cylinder II 1204 pushes the first cylinder slider 5301, connected to the robotic arm 65, downwards until the first vacuum nozzle 6001 contacts the module. The first vacuum nozzle 6001 performs vacuuming and suction, picking up the module. Driving the fourth precision slide cylinder II 1204 pushes the first cylinder slider 5301, connected to the robotic arm 65, upwards to the limit. Driving the servo motor 8, connected to the fourth threaded screw, rotates forward, driving the fourth precision slide cylinder II 1204 to move to the right to the output conveyor belt device limit.

Driving the second synchronous motor 3002 can drive the second conveyor belt 1702 to rotate clockwise.

[0147] Working principle: The second synchronous motor 3002 driving the output conveyor belt device can drive the second conveyor belt 1702 to rotate clockwise, so that the FOG component is placed at the left end of the second conveyor belt 1702 and moves to the right end as the second conveyor belt 1702 rotates, so that the module product falls onto the output conveyor belt device and moves smoothly from left to right with the output conveyor belt device, so as to output the module product.

[0148] Application scope and effects:

[0149] This solution is applicable to the assembly of 1.77-2.8 inch TFT-type backlightless LCD display modules. It realizes a series of automated operations, including automatic feeding, automatic correction, automatic alignment, automatic bonding of FOG components and backlight assembly, and automatic bending assembly. It can realize the full-process automation of TFT-type backlightless LCD display modules, achieve a unified assembly standard, and solve common problems such as light leakage, lamp holes, and FPC distortion caused by the assembly of backlightless and FOG components in TFT-type LCD display modules, which affect the display effect and structure. It effectively improves the product quality and process efficiency of backlightless TFT LCD display modules.

[0150] The present invention proposes a liquid crystal display module manufacturing equipment scheme with no light source backlight and FOG assembly, which has the following advantages compared with the prior art:

[0151] 1. Full-process automation: Achieve unmanned operation from material feeding, alignment, bonding, bending to output;

[0152] 2. High-precision alignment: Micrometer-level alignment is achieved through a vision camera and servo system, avoiding human error;

[0153] 3. High-efficiency dual-platform interaction: The first backlight feeding platform and the second backlight feeding platform work alternately, shortening the cycle time;

[0154] 4. High quality stability: Unified process standards fundamentally solve quality problems such as light leakage, lamp holes, and FPC distortion caused by non-standard assembly;

[0155] 5. Flexibility and applicability: The solution is suitable for 1.77-2.8 inch TFT backlight modules without light source and can be extended to products of similar size.

[0156] Example 2:

[0157] A method for manufacturing a liquid crystal display module with a light-free backlight and FOG assembly, achieved using the aforementioned equipment, includes the following steps:

[0158] S1, FOG component feeding: The FOG component that follows the previous bonding process is conveyed by the first conveyor belt. The protective film on the FOG component is automatically removed by the roll tape. The FOG component feeding and positioning block corrects the FOG component to a 90° direction. The conveying stops after the FOG component with the protective film removed is in place by the sensing fiber optic.

[0159] Specifically, the FOG assembly 47 is placed on the first conveyor belt 1701, which is driven clockwise by the first synchronous motor 3001, causing the FOG assembly 47 to move from left to right. The roll of adhesive tape 2401 adheres to the FOG assembly 47 under the pressure of the first guide roller 2501 and the second guide roller 2502. As the recycling motor drives the recycling roll shaft 23 to rotate counterclockwise, it pulls the FOG assembly, causing the protective film on the FOG assembly to automatically separate. The FOG assembly 47 continues to move to the right, pushed backward by the extension of the FOG assembly feed alignment block 27. It slides along the edge of the FOG assembly feed alignment block 27 until it reaches a 90° vertical angle, and then stops conveying after entering the sensing area of ​​the sensing fiber optic cable 26.

[0160] S2, FOG component loading: The robotic arm picks up the FOG components after the film is torn off and transfers them to the FOG loading platform, where they are fixed by vacuum adsorption;

[0161] Specifically, the first servo asynchronous motor 101 drives the first threaded screw 401 to reverse, the first precision slide cylinder II 1201 drives the robotic arm 65 to move to the left to the fiber optic sensing area, the first cylinder piston rod 5401 drives the robotic arm 65 to move downward, and the first vacuum nozzle 6001 vacuum sucks up the FOG component with the protective film torn off; after the robotic arm 65 moves upward, the first servo asynchronous motor 101 drives the first threaded screw 401 to rotate forward, the robotic arm 65 moves to the right above the FOG loading platform 19, and moves downward until the FOG component contacts the FOG loading platform 19, the first vacuum nozzle 6001 releases air, and the FOG loading platform 19 vacuum sucks up and fixes the FOG component.
