Description

Technical Field

[0001] This invention relates to the field of material handling and conveying technology, and more specifically, to a material handling and conveying mechanism for a fully automatic backlight assembly machine. Background Technology

[0002] As a core component of LCD devices, the assembly and processing precision of backlight modules directly determines the optical performance and finished product quality of the final display product. Fully automated backlight assembly machines are the core equipment for the mass production of backlight modules. Existing equipment generally uses multiple linear drive modules combined with pneumatic clamping mechanisms to achieve automated material handling and continuous conveying of backlight modules between the hopper station, transfer station, and various processing stations, effectively replacing manual operation and improving the overall processing efficiency of the production line. As backlight modules iterate towards ultra-thinness and narrow bezels, the industry has placed more stringent requirements on the cleanliness of the conveying process, clamping stability, and material placement accuracy, gradually revealing the structural limitations of existing material handling and conveying mechanisms.

[0003] Under long-term, high-speed, continuous operation, existing material handling and conveying mechanisms have several performance shortcomings: the open conveying path cannot isolate foreign objects, and external debris can easily interfere with the operation of the mechanism, causing jamming failures; because the workpiece will adhere to the pallet, the traditional clamping structure can only contact the workpiece with the bottom of the clamping bar, resulting in concentrated clamping force and unstable contact. Relying solely on the bottom of the clamping bar to restrain the workpiece can easily lead to uneven clamping force, causing the workpiece to slide and fall due to inertia during acceleration, deceleration, and reversal. Increasing the clamping force will further aggravate the deformation and damage of the workpiece; at the same time, the accumulation of gaps caused by long-term wear of the transmission mechanism will cause the transfer landing point to gradually shift, and the material placement positioning accuracy will continuously decrease, ultimately leading to workpiece misalignment and a large number of defective products, which seriously restricts the production yield and operational reliability of the equipment in the long term. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a material handling and conveying mechanism for a fully automatic backlight assembly machine.

[0005] The technical solution is as follows: A fully automatic backlight assembly machine material handling and conveying mechanism includes a frame, with a supplementary light fixedly connected to the top inner side of the frame, two material troughs fixedly connected to the bottom inner side of the frame, a linear module one fixedly connected inside the frame, a movable disk one mounted on the linear module one, a pneumatic clamp one mounted on the top inner side of the frame, a pneumatic clamp two mounted on the bottom inner side of the frame away from the pneumatic clamp one, a shelf fixedly connected to the side of the linear module one away from the material troughs, a linear module two fixedly connected to the side of the shelf away from the linear module one, a movable disk two mounted on the linear module two, and a transfer component for clamping and conveying the backlight module inside the frame. The transfer assembly includes a linear module three fixedly connected to the inner side of the frame. A transfer base is provided on the linear module three. An electric telescopic rod is fixedly connected to the end of the transfer base away from the linear module three. A guide frame is fixedly connected to the bottom of the telescopic shaft of the electric telescopic rod. Clamping frames are slidably connected to both ends of the guide frame. Two clamping rods are fixedly connected to the bottom of each clamping frame. Two electric cylinders symmetrical about the electric telescopic rod are fixedly connected to the upper surface of the guide frame. The telescopic shafts of the two electric cylinders are fixedly connected to the top of the two clamping frames respectively. A protective component is provided on the linear module three for protection during the process of clamping and transporting the backlight module by the transfer assembly. The protective assembly includes multiple fixing plates that are bolted to the linear module three. The ends of the multiple fixing plates away from the linear module three are bolted together to a protective shell. The bottom of both clamping frames is provided with anti-drop components to prevent the backlight module from falling during transportation. The anti-drop component includes two fixed frames 2 fixedly connected to the lower surface of the clamping frame. Each of the two fixed frames 2 has a bracket rotatably connected to the side of the two fixed frames 2 that is far apart from each other. The movable disk 2 is provided with an adjustment component for adjusting the placement position of the backlight module. The adjustment assembly includes an adjustment frame 2 mounted on a movable disk 2. Guide frames 1 are fixedly connected to the four corners of the upper surface of the adjustment frame 2 by bolts, and guide frames 2 are fixedly connected to both ends of the guide frames by bolts.

[0006] Furthermore, linear module one drives moving disk one to move horizontally. The two material racks correspond to the positions of pneumatic clamp one and pneumatic clamp two, respectively. Both pneumatic clamp one and pneumatic clamp two have lifting functions. The material rack corresponding to the position of pneumatic clamp one contains a tray for supporting and transferring the backlight module. Both material racks are equipped with conveying devices for moving and stacking the trays. Linear module two drives moving disk two to move horizontally.

[0007] Furthermore, the linear module three-drive transfer base moves in the horizontal direction. The guide frame consists of a polygonal plate and two crossbars. Both ends of the two clamping frames are provided with holes corresponding to the two crossbars of the guide frame. The bottoms of multiple clamping rods are fixedly connected with rubber sleeves. The guide frame is located inside the protective shell.

[0008] Furthermore, both clamping frames are equipped with lifting components to prevent the clamping rods from inadvertently clamping the backlight module. The lifting components include a fixed frame 1 fixedly connected to the side of the clamping frame near the guide frame. Two movable rods are slidably connected to the fixed frame 1. The ends of the two movable rods near the clamping frame are jointly fixedly connected to a translation frame. A first spring is sleeved on the outer surface of each of the two movable rods. The two ends of the first spring are respectively fixedly connected to the end of the movable rod away from the clamping frame and the surface of the fixed frame 1. Two sets of pulleys are rotatably connected to the inner side of the translation frame. Each set of pulleys has two pulleys. A transmission belt is connected to the outer surface of the two sets of pulleys. A connecting plate is fixedly connected to the outer surface of the transmission belt. An abutment rod is fixedly connected to the connecting plate. An abutment ball is rotatably connected to the bottom end of the abutment rod. A second spring is sleeved on the outer surface of the abutment rod. The upper and lower ends of the second spring are respectively fixedly connected to the upper surface of the connecting plate and the translation frame.

[0009] Furthermore, the translation frame consists of an inverted U-shaped frame and a convex plate, wherein the convex plate of the translation frame corresponds to the position of the abutment rod, and the top of the abutment rod slides vertically on the convex plate of the translation frame, and the connecting plate is located on the side of the transmission belt away from the electric telescopic rod.

[0010] Furthermore, the anti-drop component also includes two toothed frames slidably connected to the outer surfaces of the two fixed frames. Gears are fixedly connected to the sides of the two brackets that are close to each other. The two toothed frames mesh with the adjacent gears respectively. Two lifting frames are fixedly connected to the side of the transmission belt that is close to the connecting plate. The two lifting frames are slidably connected to the adjacent toothed frames respectively.

[0011] Furthermore, grooves are provided on both sides of the fixing frame 2. The gear frame is composed of a C-shaped block, a U-shaped gear, and a round hole block. The bracket is composed of a round plate and a long rod. The long rod of the bracket protrudes from the outer surface of the clamping rod. The lifting frame is composed of an L-shaped rod and a round rod. The round rod of the lifting frame is slidably connected to the round hole block of the gear frame.

[0012] Furthermore, the adjustment assembly also includes an adjustment frame 1 fixedly connected to the movable disk 2. Two guide rods are fixedly connected to the adjustment frame 1. The adjustment frame 2 is slidably connected to the two guide rods. Two third springs are sleeved on each of the two guide rods. The two ends of each third spring are fixedly connected to the adjustment frame 2 and the adjustment frame 1, respectively.

[0013] Furthermore, the bottom end of each guide frame one is set to be inclined, and the bottom end of each guide frame two is also set to be inclined, with the bottom shape of guide frame one matching the shape of guide frame two.

[0014] Based on the above, the beneficial effects of the fully automatic backlight assembly machine material conveying mechanism of the present invention are as follows: The protective shell forms a closed protective space during the clamping and conveying of the backlight module, effectively preventing external dust, floating dust and foreign objects from falling onto the surface of the backlight module, avoiding the optical film from being contaminated and producing bright spots, dirt and defects, and greatly reducing the product scrap rate. At the same time, the protective shell can prevent external debris from interfering with the operation of the clamping and conveying mechanism, reducing the risk of jamming and scratching, improving the stability of the conveying operation, and effectively improving the production efficiency and product yield of multi-station continuous processing. The backlight module, which is in contact with the conveyor belt, moves upward through the belt, allowing it to reach the middle section of the clamping rod. This avoids the backlight module being only in contact with the bottom of the clamping rod, which would result in insufficient friction and make it easy for the backlight module to slip off during transport, start-up, or lifting. The middle section provides sufficient clamping contact length, ensuring a close fit between the clamping rod and the backlight module. Even if the backlight module slips off a certain distance, the lower part of the clamping rod can still provide clamping force, thereby increasing the clamping contact length, improving clamping stability, and ensuring the stability of the clamping during subsequent transport. This prevents the backlight module from accidentally falling off during transport. By rotating the bracket in the opposite direction, the long rod on it rotates to the bottom of the backlight module, thereby supporting the backlight module and preventing it from falling due to instability during clamping and transportation. It can effectively prevent the workpiece from slipping and falling due to rotational inertia and equipment vibration without increasing the clamping pressure, thus eliminating workpiece falling and scrapping and equipment jamming failure. At the same time, it does not increase the pressure on the clamping surface, avoiding edge damage to the backlight module and displacement of optical films. It balances transportation safety and product quality, is suitable for high-speed continuous processing scenarios, and improves equipment operation reliability and finished product yield. Each time the backlight module is adjusted by the position of the adjustment bracket two, it can accurately stop at the same position of the moving plate two. This allows the moving plate two to accurately transport the backlight module to the processing position, improving the accuracy of backlight module processing and avoiding situations where the backlight module is misaligned during feeding, resulting in inaccurate processing.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] The embodiments provided by the present invention will be described in detail below: like Figures 1 to 5As shown, a fully automatic backlight assembly machine material handling and conveying mechanism includes a frame 1. A supplementary light 2 is fixedly connected to the top inner side of the frame 1. Two material trays 3 are fixedly connected to the bottom inner side of the frame 1. A linear module 4 is fixedly connected inside the frame 1. A movable disk 41 is provided on the linear module 4. A pneumatic clamp 42 is provided on the top inner side of the frame 1. A pneumatic clamp 43 is provided on the bottom inner side of the frame 1 away from the pneumatic clamp 42. A shelf 44 is fixedly connected to the side of the linear module 4 away from the material trays 3. A linear module 45 is fixedly connected to the side of the shelf 44 away from the linear module 4. A movable disk 46 is provided on the linear module 45. A transfer component for clamping and conveying the backlight module is provided inside the frame 1. The transfer assembly includes a linear module 3 51 fixedly connected to the inner side of the frame 1. A transfer base 52 is provided on the linear module 3 51. An electric telescopic rod 53 is fixedly connected to the end of the transfer base 52 away from the linear module 3 51. A guide frame 54 is fixedly connected to the bottom of the telescopic shaft of the electric telescopic rod 53. Clamping frames 55 are slidably connected to both ends of the guide frame 54. Two clamping rods 56 are fixedly connected to the bottom of the two clamping frames 55. Two electric cylinders 57 are fixedly connected to the upper surface of the guide frame 54 symmetrically about the electric telescopic rod 53. The telescopic shafts of the two electric cylinders 57 are fixedly connected to the top of the two clamping frames 55 respectively. A protective component is provided on the linear module 3 51 for protection during the process of the transfer assembly clamping and transporting the backlight module. The protective assembly includes multiple fixing plates 81 that are bolted to the linear module 3 51, and the ends of the multiple fixing plates 81 that are away from the linear module 3 51 are bolted together to a protective shell 82.

[0019] It should be noted that the linear module 4 drives the moving disk 41 to move horizontally. This means that after the pneumatic clamp 42 places the pallet in the material rack 3 onto the moving disk 41, the pneumatic clamp 42 drives the moving disk 41 to move the pallet to a position easily gripped by the pneumatic clamp 43. The two material racks 3 correspond to the positions of the pneumatic clamps 42 and 43 respectively. Both pneumatic clamps 42 and 43 have lifting functions, allowing for different height clamping and transfer of pallets without affecting the horizontal transport of the pallet by the moving disk 41. The material rack 3 corresponding to the position of the pneumatic clamp 42 contains a pallet for supporting and transferring the backlight module. The backlight module is placed on the pallet. Both material racks 3 are equipped with mechanisms for moving and stacking. The pallet conveying device includes a conveying device in the material rack 3 corresponding to the position of pneumatic clamp 42, which is used to convey the pallet to a position that is easy for pneumatic clamp 42 to hold. The conveying device in the material rack 3 corresponding to the position of pneumatic clamp 43 can adaptively adjust the position of the highest pallet after the pneumatic clamp 43 places the pallet in the material rack 3 below it, so as to facilitate the placement of subsequent pallets. The material rack 3 corresponding to pneumatic clamp 42 is used to place the pallet containing the backlight module, and the material rack 3 corresponding to pneumatic clamp 43 is used to store the pallet after the backlight module is removed. That is, one is used for loading and the other is used for unloading. The linear module 2 45 drives the moving disk 2 46 to move horizontally, which is used to horizontally convey the backlight module placed on it to the processing area.

[0020] To further explain, the linear module 51 drives the transfer base 52 to move horizontally. The guide frame 54 consists of a polygonal plate and two crossbars. Both ends of the two clamping frames 55 are provided with holes corresponding to the two crossbars of the guide frame 54. The outer surfaces of multiple clamping rods 56 near the bottom are fixedly connected with rubber sleeves for soft contact with the backlight module. The guide frame 54 is located inside the protective shell 82, which prevents collisions when the clamping rods 56 clamp and transport the backlight module.

[0021] Specifically, the backlight module is placed on a tray, which is then stacked in the material rack 3 corresponding to the position of pneumatic clamp 42. The conveying device within the material rack 3 transports the stacked trays to a position easily grasped by pneumatic clamp 42. The controller then controls pneumatic clamp 42 to grasp the highest-positioned tray and move it upwards. Pneumatic clamp 42 then moves the tray upwards. Next, the controller controls linear module 4 to drive moving disk 41 downwards from pneumatic clamp 42. Pneumatic clamp 42 then stops gripping the tray, and the gripped tray falls onto moving disk 41. Finally, the controller controls linear module 4 to drive moving disk 41 to one side of pneumatic clamp 43. The first 41 will only move to the bottom of the guide frame 54. Then, the controller controls the telescopic shaft of the electric telescopic rod 53 to extend downward. The telescopic shaft of the electric telescopic rod 53 drives the guide frame 54 to move downward synchronously. The guide frame 54 drives the clamping rod 56 to move downward synchronously through the clamping frame 55. When the clamping rod 56 moves to the position above the tray, that is, when the bottom end of the clamping rod 56 is about to approach the upper surface of the tray, the clamping rods 56 on the two clamping frames 55 are respectively located on both sides of the backlight module on the tray. Then, the controller controls the telescopic shafts of the two electric cylinders 57 to retract. The telescopic shafts of the two electric cylinders 57 will pull the two clamping frames 55 closer to each other on the crossbar of the guide frame 54. Then, the two clamping frames 55 will respectively drive the two clamping rods 56 below them to abut against the backlight module. Two clamping rods 56 on both sides of the optical module clamp the backlight module. Then, the controller controls the telescopic shaft of the electric telescopic rod 53 to retract upwards. After the telescopic shaft of the electric telescopic rod 53 retracts, the clamped backlight module moves upwards synchronously. At this time, the backlight module is moved into the protective shell 82. Then, the controller causes the linear module three 51 to drive the transfer base 52 to move horizontally. At this time, the transfer base 52 moves towards the side closer to the shelf 44. The transfer base 52, through the electric telescopic rod 53, causes the guide frame 54 to move synchronously towards the side closer to the shelf 44 inside the protective shell 82. When the guide frame 54 moves above the shelf 44, it pauses briefly. When the moving disk two 46 has the previous work When a backlight module is being processed, if the backlight module is completed on the second moving plate 46 and then picked up and transported by another material handling and conveying mechanism, there is no backlight module on the second moving plate 46 at this time. At the same time, the controller controls the linear module 45 to drive the second moving plate 46 to move horizontally. When the second moving plate 46 moves to the position corresponding to the guide frame 54, that is, under the continued driving action of the linear module 51, the transfer base 52 can move upward closer to the second moving plate 46. Then, the transfer base 52 moves the guide frame 54 above the second moving plate 46 through the electric telescopic rod 53. Then, the controller controls the extension shaft of the electric telescopic rod 53 to extend, and the extension shaft of the electric telescopic rod 53 will drive the guide frame 54 to move downward closer to the second moving plate 46.Finally, the controller controls the extension and retraction of the two electric cylinders 57. These cylinders cause the two clamping frames 55 to move away from each other on the crossbar of the guide frame 54. At this time, the two clamping frames 55 cause the clamping rods 56 below to move away from each other, thus the clamping rods 56 no longer clamp the backlight module. The backlight module is then placed on the second moving plate 46. The horizontal conveying of the second moving plate 46 transports the backlight module to the processing area for processing.

[0022] During the movement of the guide frame 54 inside the protective shell 82, the guide frame 54 causes the clamping frame 55 to move synchronously with the clamped backlight module inside the protective shell 82 via the clamping rod 56. The protective shell 82 forms a closed protective space during the clamping and conveying of the backlight module, effectively isolating external dust, floating dust and foreign objects from falling onto the surface of the backlight module, avoiding contamination of the optical film and causing bright spots, dirt and defects, and significantly reducing the product scrap rate. At the same time, the protective shell 82 can prevent external debris from interfering with the operation of the clamping and conveying mechanism, reducing the risk of jamming and scratching, improving the stability of the conveying operation, and effectively improving the production efficiency and product yield of multi-station continuous processing.

[0023] like Figures 5 to 8 As shown, both clamping frames 55 are equipped with lifting components to prevent the clamping rods 56 from inadvertently clamping the backlight module. Each lifting component includes a fixed frame 61 fixedly connected to the side of the clamping frame 55 near the guide frame 54. Two movable rods 62 are slidably connected to the fixed frame 61. A translation frame 63 is fixedly connected to the ends of the two movable rods 62 near the clamping frame 55. A first spring 64 is sleeved on the outer surface of each of the two movable rods 62. The two ends of the first spring 64 are respectively fixedly connected to the ends of the movable rods 62 away from the clamping frame 55. On the surface of the fixed frame 61, two sets of pulleys 65 are rotatably connected to the inner side of the translation frame 63. Each set of pulleys 65 has two pulleys. The outer surfaces of the two sets of pulleys 65 are connected to a transmission belt 66. A connecting plate 67 is fixedly connected to the outer surface of the transmission belt 66. An abutment rod 68 is fixedly connected to the connecting plate 67. An abutment ball 69 is rotatably connected to the bottom end of the abutment rod 68. A second spring 610 is sleeved on the outer surface of the abutment rod 68. The upper and lower ends of the second spring 610 are fixedly connected to the upper surface of the connecting plate 67 and the translation frame 63, respectively.

[0024] It should be noted that the translation frame 63 consists of an inverted U-shaped frame and a convex plate. The outer surface of the transmission belt 66 is provided with a flexible anti-static layer to prevent edge scratches, diaphragm displacement, dust transfer, or electrostatic adsorption contamination when the transmission belt 66 contacts both sides of the backlight module. When the transmission belt 66 contacts the backlight module, it mainly contacts the non-display border area of ​​the backlight module edge. The convex plate of the translation frame 63 corresponds to the position of the contact rod 68, and the top of the contact rod 68 slides vertically on the flat plate. On the convex plate of the transfer frame 63, the outer wall of the abutment rod 68 is frosted to increase the frictional force of sliding contact with the convex plate of the transfer frame 63. The connecting plate 67 is located on the side of the transmission belt 66 away from the electric telescopic rod 53. In addition, the abutment rod 68 causes the abutment ball 69 to protrude from the lower surface of the clamping rod 56, that is, the height of the abutment ball 69 is lower than the height of the lower surface of the clamping rod 56. When the abutment ball 69 abuts against the tray, the abutment rod 68 can move upward through the connecting plate 67, thereby causing the transmission belt 66 to perform transmission.

[0025] Specifically, when the telescopic shaft of the aforementioned electric telescopic rod 53 extends downward, the clamping rod 56 moves downward toward the upper surface of the tray. During this process, the abutment ball 69 first comes into contact with the tray. Once the abutment ball 69 contacts the tray, the abutment rod 68 cannot continue to move downward. The abutment rod 68 also prevents the connecting plate 67 from moving downward. As the clamping frame 55 continues to move downward, it drives the fixed frame 61 to move downward synchronously. The fixed frame 61, through the movable rod 62, drives the translation frame 63 to move downward synchronously. The translation frame 63, through the pulley 65, drives the transmission belt 66 to move downward synchronously. During the downward movement of the transmission belt 66, the connection plate 67 restricts its movement. Simultaneously, as the translation frame 63 continues to move downward, its protrusion slides downward on the outer surface of the connecting plate 67. At the same time, the protrusion of the translation frame 63 compresses the second spring 610. Then... The controller controls the retraction of the telescopic shafts of the two electric cylinders 57. When the two electric cylinders 57 drive the two clamping frames 55 to move closer to each other, the clamping frames 55 will drive the fixed frame 61 to move synchronously. The fixed frame 61 will cause the first spring 64 to drive the translation frame 63 to move synchronously through the movable rod 62. Then, the translation frame 63 will drive the transmission belt 66 through the pulley 65 to contact the two sides of the backlight module first, before the clamping rod 56. That is, the side of the transmission belt 66 away from the connecting plate 67 will contact the two sides of the backlight module. Under the restriction of the backlight module, the transmission belt 66 will prevent the translation frame 63 from moving horizontally through the pulley 65. In addition, the translation frame 63 will also prevent the movable rod 62 from moving. Then, as the clamping frame 55 continues to move, it will drive the fixed frame 61 to continue to move synchronously. The fixed frame 61 will compress the first spring 64. Finally, as the clamping frame 55 continues to move, the clamping rod 56 will contact the two sides of the backlight module.

[0026] After the backlight module is clamped, the controller controls the telescopic shaft of the electric telescopic rod 53 to retract upwards. At this time, the telescopic shaft of the electric telescopic rod 53 will drive the clamping frame 55 to move upwards synchronously through the guide frame 54. The clamping frame 55 will drive the clamped backlight module to move upwards through the clamping rod 56. When the clamping frame 55 moves upwards, it will drive the fixing frame 61 to move upwards. The upward movement of the fixing frame 61 will drive the translation frame 63 to move upwards synchronously through the movable rod 62. The translation frame 63 will drive the transmission belt 66 to move upwards synchronously through the pulley 65. At this time, under the elastic reset action of the second spring 610, the connecting plate 67 will move downwards. The connecting plate 67 will slide downwards on the convex plate of the translation frame 63. During this process, the connecting plate 67 will cause the transmission belt to move downwards. When the belt pulley 65 reverses its transmission, the reverse-driven belt 66 will drive the backlight module that is in contact with it to move upward. This allows the backlight module to move to the middle section of the clamping rod 56, avoiding the situation where only the bottom end of the clamping rod 56 contacts the backlight module. This prevents the backlight module from easily slipping off during transport, start-up, or lifting due to insufficient friction at the bottom end of the clamping rod 56. The middle section has a sufficient clamping contact length, and the clamping rod 56 and the backlight module are fully engaged. Even if the backlight module slips off a certain distance, the lower part of the clamping rod 56 can still provide clamping force, thereby increasing the clamping contact length, improving clamping stability, ensuring the stability of clamping during subsequent transport, and preventing accidental drops during the transport of the backlight module.

[0027] It should be noted that, as the contact ball 69 contacts the tray, and then the two clamping frames 55 drive the clamping rod 56 to clamp the backlight module, the contact ball 69 will roll on the tray, which can avoid damage to the tray or pushing the tray to move out of place. Furthermore, when the contact rod 68 slides vertically on the convex plate of the translation frame 63, the outer wall of the contact rod 68 is frosted, which increases the frictional force of sliding contact with the convex plate of the translation frame 63. Therefore, it can dampen the downward sliding speed of the connecting plate 67, and prevent the connecting plate 67 from sliding down too fast when the second spring 610 resets, so that the transmission belt 66 slowly drives the backlight module to move upward and can be smoothly stopped at the middle position of the clamping rod 56.

[0028] like Figures 6 to 9As shown, both clamping frames 55 are equipped with anti-drop components at their bottoms to prevent the backlight module from falling during transport. The anti-drop components include two fixed frames 71 fixedly connected to the lower surface of the clamping frame 55. The outer surfaces of the two fixed frames 71 are slidably connected with gears 72. The sides of the two fixed frames 71 that are far apart from each other are rotatably connected with brackets 73. The sides of the two brackets 73 that are close to each other are fixedly connected with gears 74. The two gears 72 mesh with the adjacent gears 74 respectively. The side of the transmission belt 66 near the connecting plate 67 is fixedly connected with two lifting frames 75. The two lifting frames 75 are slidably connected with the adjacent gears 72 respectively.

[0029] It should be noted that the two sides of the fixing frame 71 are provided with grooves. The tooth frame 72 is composed of a C-shaped block, a U-shaped toothed rod and a round hole block. The C-shaped block of the tooth frame 72 cooperates with the groove of the fixing frame 71 to ensure that the tooth frame 72 can only slide vertically along the fixing frame 71 without slipping. The bracket 73 is composed of a round plate and a long rod. The long rod of the bracket 73 protrudes from the outer surface of the clamping rod 56. The lifting frame 75 is composed of an L-shaped rod and a round rod. The round rod of the lifting frame 75 is horizontally slidably connected to the round hole block of the tooth frame 72.

[0030] Specifically, during the backlight module clamping process described above, when the transmission belt 66 is in normal operation, it drives the lifting frame 75 to move upward. During this upward movement, the lifting frame 75 drives the gear frame 72 to move upward on the outer surface of the fixed frame 71 via the round rod. Then, during the upward movement of the gear frame 72, it drives the meshing gear 74 to rotate. The rotation of the gear 74 drives the bracket 73 to rotate synchronously. After the bracket 73 rotates, the long rod on it rotates to... Figure 8As shown on the left, this will not affect the clamping bar 56's resistance to the backlight module. Finally, when the electric telescopic rod 53 retracts upward along its telescopic axis, the electric telescopic rod 53 will drive the clamping frame 55 to move upward through the guide frame 54. When the clamping frame 55 drives the backlight module upward through the clamping bar 56, the aforementioned transmission belt 66 begins to reverse its transmission, causing the backlight module to move upward a short distance. The other side of the transmission belt 66 will drive the lifting frame 75 to move downward. The lifting frame 75 will drive the gear frame 72 to move downward on the fixed frame 71. The gear frame 72 will drive the gear 74 meshing with it to rotate in the opposite direction. 4 will cause the bracket 73 to rotate in the opposite direction. The long rod on the bracket 73 will rotate to the bottom of the backlight module, thereby supporting the backlight module and preventing the clamping rod 56 from becoming unstable and falling during the clamping and transfer of the backlight module. It can effectively prevent the workpiece from sliding and falling due to rotational inertia and equipment vibration without increasing the clamping pressure, thus eliminating workpiece falling and scrapping and equipment jamming failure. At the same time, it will not increase the pressure on the clamping surface, avoiding edge damage to the backlight module and displacement of the optical film. It takes into account the transfer safety and product quality, adapts to high-speed continuous processing scenarios, and improves the reliability of equipment operation and the yield of finished products.

[0031] It should be noted that when the translation frame 63 slides on the fixed frame 61 via the movable rod 62, the translation frame 63 drives the transmission belt 66 to move synchronously via the pulley 65. The transmission belt 66 then drives the lifting frame 75 to slide synchronously on the gear frame 72. Therefore, the sliding of the lifting frame 75 will not affect the state of the gear frame 72 after it moves upward.

[0032] To further explain, when the backlight module is placed on the second movable disk 46, the process is the same as the steps after the lifting component moves downward. That is, the transmission belt 66 of the lifting component will drive the backlight module, which is clamped between the clamping bars 56, to move downward synchronously. When it approaches the second movable disk 46, the backlight module will move downward towards the second movable disk 46 first due to the transmission of the transmission belt 66, so that the backlight module can be placed stably on the second movable disk 46. During this process, due to the transmission of the transmission belt 66, the lifting frame 75 will drive the gear frame 72 to move upward on the outer surface of the second fixed frame 71. The gear frame 72 will cause the gear 74 that meshes with it to drive the bracket 73 to rotate outward. This can prevent the bracket 73 from affecting the downward movement of the backlight module driven by the transmission belt 66. That is, the bracket 73 will not obstruct the backlight module that is lowered and placed on the second movable disk 46, so that the backlight module is effectively and stably placed on the second movable disk 46.

[0033] like Figure 4 , Figure 5 and Figure 10As shown, the movable disk 2 46 is provided with an adjustment component for adjusting the placement position of the backlight module. The adjustment component includes two adjustment frames 1 91 fixedly connected to the movable disk 2 46. Two guide rods 92 are fixedly connected to the adjustment frame 1 91. The two guide rods 92 are slidably connected to the adjustment frame 2 93. Two third springs 94 are sleeved on each of the two guide rods 92. The two ends of each third spring 94 are fixedly connected to the adjustment frame 2 93 and the adjustment frame 1 91 respectively. The four corners of the upper surface of the adjustment frame 2 93 are fixedly connected to the guide frame 1 95 by bolts. The two ends of the crossbar of the guide frame 54 are fixedly connected to the guide frame 2 96 by bolts.

[0034] It should be noted that the bottom of each guide frame 95 is set to be inclined, and the bottom of each guide frame 96 is set to be inclined. The bottom shape of the guide frame 95 is adapted to the shape of the guide frame 96.

[0035] Specifically, when the backlight module is placed on the moving disk 46 by the transfer component, the transfer component will move to the position corresponding to the moving disk 46. However, during long-term operation, the gap will inevitably widen due to wear between the mechanisms, and the actual landing point of the transfer component will deviate from the set landing point. The misalignment will become more obvious over a long period of operation, making it impossible to guarantee that the backlight module is accurately located in the processing position. To ensure that each backlight module is accurately placed in the same position on the moving disk 46, when the transfer component moves downward and approaches the moving disk 46, the guide frame 54 in the transfer component will drive the four guide frames 96 on it to move downward synchronously. Then, the guide frame 96 will abut against the skewed part of the guide frame 95 through the skewed part at its bottom. Under the guiding action of the abutment between the guide frame 95 and the guide frame 96, the adjustment frame 93 can slide longitudinally on the guide rod 92. During the sliding of the adjustment frame 93, the third spring 94 will be stretched and compressed. With the adjustable frame 2 93, which can be adjusted vertically to horizontally, even if the transfer components are misaligned, the backlight module can still be accurately placed on the adjustable frame 2 93. Subsequently, the guide frame 1 95 disengages from the guide frame 2 96, and the third spring 94 will also reset, causing the adjustable frame 2 93 to return to its initial position. This ensures that the backlight module can accurately stop at the same position on the moving plate 2 46 each time the position is adjusted by the adjustable frame 2 93, so that the moving plate 2 46 can accurately transport the backlight module to the processing position. This improves the accuracy of backlight module processing and avoids the situation where the backlight module is misaligned and cannot be accurately processed.
