Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal display screen production, and specifically relates to an operating table for liquid crystal display screen production. Background Art

[0002] When producing liquid crystal display screens, a large number of processes are required, including module processes, where a substrate, a polarizer, a circuit board, and other structures are combined into one, and then subsequent steps are carried out. When attaching the polarizer to the substrate, it is usually necessary to attach polarizers to both sides of the substrate, which means that during the attachment process, it is necessary to flip and replace the exposed surface of the substrate. However, in the prior art, the form of manually flipping the substrate by hand is usually adopted to adjust and replace the exposed surface of the substrate. Since liquid crystal display screens need to be mass-produced and the production efficiency in the factory needs to be maintained, the traditional flipping method will bring great inconvenience to the production of liquid crystal display screens in this form. The cumulative flipping time of each substrate will cause a large amount of production time of the liquid crystal display screen to be consumed, ultimately affecting the factory's benefits and being not conducive to use.

[0003] In addition, since the prior art uses a manual method to flip the substrate on the operating table, and the tabletop is usually relatively empty and there are no relevant auxiliary control structures, and it is flipped only by the operator's own feeling, the position of the substrate after flipping will be offset from the position of the substrate before flipping. For an automated attachment process, the substrate needs to ensure that its position does not change after flipping in order to achieve the best attachment effect of the polarizer. Otherwise, the offset of the substrate's moving position will also cause deviations in the attachment of the polarizer, thereby affecting the subsequent processing of the substrate.

[0004] Therefore, in view of this, the present invention proposes an operating table for liquid crystal display screen production to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides an operating table for liquid crystal display screen production to solve the corresponding technical problems raised in the above background art.

[0006] To achieve the above object, the technical solution adopted by the present invention is: an operating table for liquid crystal display screen production, including a table body, positioning plates are symmetrically and fixedly installed on the top of the table body, and a synchronous flipping assembly is connected between the outer walls on both sides of the table body;

[0007] The synchronous flipping assembly includes side plates symmetrically fixed on both sides of the table body. Moving grooves are provided on the opposite sides between the side plates. A moving block is slidably connected inside the moving groove. A rotating shaft is rotatably connected to the upper end of the side plate. A fixed clamping assembly is connected between the rotating shafts. On the outer ring surfaces of the opposite ends between the rotating shafts, a special-shaped plate is fixedly installed. A groove is provided on one side of the special-shaped plate. On the side of the moving block away from the side plate, a cross bar and a dial rod are respectively fixedly installed, and the dial rod is adapted to the groove. Between the inner walls of the lower ends on both sides of the side plate, a limiting rod is fixedly installed. At the bottom of the moving block, a sleeve block is fixedly installed, and the sleeve block is slidably sleeved on the outer ring surface of the limiting rod.

[0008] Further, an installation frame is fixedly installed at the lower end of the front side of the table body. A linkage shaft is rotatably connected to the installation frame. On the outer ring surfaces of both ends of the linkage shaft, main rods are fixedly connected. On the outer ring surface of the middle part of the linkage shaft, a sleeve is fixedly connected. On the outer ring surface of the sleeve block facing the installation frame, a connecting shaft is fixedly installed. A linkage rod is rotatably connected to the outer ring surface of the connecting shaft, and the other end of the linkage rod is rotatably connected to the main rod.

[0009] Further, the fixed clamping assembly includes fixed frames symmetrically distributed between the rotating shafts, and the fixed frames are fixedly connected to the rotating shafts. A bracket is fixedly connected between the fixed frames, and a flipping positioning assembly is installed at the bottom of the bracket.

[0010] Further, fixed blocks are fixedly installed at the bottom of the fixed frames. Arc-shaped blocks are fixedly installed on the opposite sides between the fixed blocks. Annular grooves are provided at the upper ends of the opposite sides between the side plates, and the arc-shaped blocks are slidably fitted inside the annular grooves.

[0011] Further, a threaded rod is rotatably connected to the center of the top of the fixed frame. A knob is fixedly installed at the top of the threaded rod. A linkage block is threadedly connected to the outer ring surface of the threaded rod. The bottom of the linkage block is fixedly connected to a fixing plate through a support rod, and a side clamping area is formed between the fixing plate and the fixed frame.

[0012] Further, on the side of the fixing plate fitting the fixed frame, sliders are symmetrically and fixedly connected. Sliding grooves are symmetrically provided on the fixed frame, and the sliders are slidably fitted inside the sliding grooves.

[0013] Further, the flipping positioning assembly includes positioning frames symmetrically fixed at both ends of the bottom of the bracket. On the side of the positioning frame facing the positioning plate, return springs are symmetrically fixedly connected. The other end of the return spring is fixedly connected to a positioning ball.

[0014] Further, positioning grooves are symmetrically provided on the opposite sides between the positioning plates, and the positioning ball is fitted and engaged with the positioning groove.

[0015] Furthermore, a slide bar is fixedly installed inside the positioning ball, and one end of the slide bar away from the positioning ball is slidably fitted inside the positioning frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (1) Before attaching the polarizer to the exposed surface of the substrate, the substrate can be fixedly placed between the two rotating shafts first. Subsequently, through the provided synchronous flipping component, the rotating shafts can be driven to rotate by 180 degrees, and simultaneously the substrate can be made to rotate accordingly, thereby changing the exposed surface of the substrate. In this way, the flipping work of the substrate can be completed without the operator manually taking and touching the substrate, saving the time of manual flipping, and further facilitating the subsequent attachment work of the polarizer to the substrate.

[0018] (2) Since the way of flipping the exposed surface of the substrate by changing the traditional manual taking and touching method of the substrate by the operator, the operator's hand does not directly contact the substrate, which can avoid the situation of squeezing and damaging the substrate due to different holding forces caused by individual differences. At the same time, the non-contact form also prevents the situation that foreign objects are adsorbed on the substrate surface due to excessive contact between the substrate and external objects.

[0019] (3) Through the provided fixed clamping component, during the process of the substrate rotating synchronously with the rotating shaft and flipping accordingly, the substrate can be clamped and fixed correspondingly, making the substrate more stable during the flipping process and not easily falling. Moreover, after the flipping work of the substrate is completed, it can also ensure that the substrate is still in the same position, preventing the position of the substrate from shifting, thereby facilitating the attachment of the polarizer to the exposed surface of the substrate and making the attachment accuracy of the polarizer more accurate.

[0020] (4) Through the provided flipping and positioning component, the substrate can be positioned between the two positioning plates when the flipping is completed, preventing the situation that the substrate is affected by external forces and the angle shifts during the attachment of the polarizer, thereby strengthening the fixation of the substrate after flipping and facilitating the attachment of the polarizer.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiments of the present invention

[0037] Please refer to Figure 1 , Figure 2 , Figure 4As shown in the figure, it includes a frustum 1, on the top of the frustum 1, positioning plates 2 are symmetrically and fixedly installed, and a synchronous flipping assembly is connected between the outer walls on both sides of the frustum 1;

[0038] The synchronous flipping assembly includes side plates 31 symmetrically and fixedly installed on both sides of the frustum 1. On the opposite sides between the side plates 31, moving grooves 32 are respectively opened. Inside the moving grooves 32, moving blocks 34 are slidably connected. At the upper ends of the side plates 31, rotating shafts 314 are rotatably connected. Between the rotating shafts 314, a fixed clamping assembly is connected. On the outer circumferential surfaces of the opposite ends between the rotating shafts 314, special-shaped plates 315 are fixedly installed. On one side of the special-shaped plates 315, grooves 316 are opened. On the sides of the moving blocks 34 away from the side plates 31, cross bars 35 and toggle rods 36 are respectively fixedly installed, and the toggle rods 36 are adapted to the grooves 316. Between the inner walls at both sides of the lower ends of the side plates 31, limiting rods 33 are fixedly installed. At the bottom of the moving blocks 34, sleeve blocks 37 are fixedly installed, and the sleeve blocks 37 are slidably sleeved on the outer circumferential surfaces of the limiting rods 33;

[0039] At the lower front end of the frustum 1, a mounting frame 311 is fixedly installed. On the mounting frame 311, a linkage shaft 312 is rotatably connected. On the outer circumferential surfaces of both ends of the linkage shaft 312, main rods 310 are fixedly connected. On the outer circumferential surface of the middle part of the linkage shaft 312, a sleeve 313 is fixedly connected. On the outer circumferential surface of the end of the sleeve block 37 facing the mounting frame 311, a connecting shaft 38 is fixedly installed. On the outer circumferential surface of the connecting shaft 38, a linkage rod 39 is rotatably connected, and the other end of the linkage rod 39 is rotatably connected to the main rod 310.

[0040] The effects achieved by this embodiment are as follows: When in use, the substrate can be first fixedly placed between the two rotating shafts 314. Compared with the prior art, it is not necessary for the operator to manually touch the substrate for picking up and flipping. By driving the moving blocks 34, under the toggling cooperation of the toggle rods 36 and the grooves 316, the special-shaped plates 315 can be rotated by 180 degrees, so that the substrate fixedly placed between the rotating shafts 314 can be driven to rotate synchronously, and the exposed surface of the substrate can be replaced, so as to attach polarizing films to both sides of the substrate;

[0041] While using the synchronous flipping assembly to drive the substrate to rotate for turning over, since it is not necessary for the operator to directly contact the substrate, it can not only prevent the situation that the operator brings foreign objects from the outside to the substrate and makes foreign objects adsorbed on the surface of the substrate, but also because the operating force of each person is different and the force for holding the substrate accurately cannot be controlled, the non-direct contact method can also avoid the situation that the substrate is damaged by extrusion due to different hand holding forces caused by individual differences.

[0042] Please refer to Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7As shown, the fixed clamping assembly includes a fixed frame 41 symmetrically distributed between the rotating shafts 314, and the fixed frame 41 is fixedly connected to the rotating shafts 314. A bracket 411 is fixedly connected between the fixed frames 41, and a flipping and positioning assembly is installed at the bottom of the bracket 411;

[0043] At the bottom of the fixed frame 41, fixed blocks 42 are fixedly installed. On the opposite sides of the fixed blocks 42, arc-shaped blocks 43 are fixedly installed. On the upper ends of the opposite sides between the side plates 31, annular grooves 317 are respectively formed, and the arc-shaped blocks 43 are slidably fitted inside the annular grooves 317;

[0044] At the center of the top of the fixed frame 41, a threaded rod 45 is rotatably connected. At the top of the threaded rod 45, a knob 46 is fixedly installed. A linkage block 47 is threadedly connected to the outer ring surface of the threaded rod 45. At the bottom of the linkage block 47, a fixed plate 49 is fixedly connected through a support rod 48, and a side clamping area is formed between the fixed plate 49 and the fixed frame 41;

[0045] On one side of the fixed plate 49 that fits the fixed frame 41, sliders 410 are symmetrically fixedly connected. On the fixed frame 41, sliding grooves 44 are symmetrically formed, and the sliders 410 are slidably fitted inside the sliding grooves 44.

[0046] The effects achieved by this embodiment are as follows: Before attaching the polarizer to the substrate, the substrate can be placed above the bracket 411. By rotating the threaded rod 45, the fixed plate 49 is driven to clamp the side of the substrate accordingly, so that the substrate is fixed between the two fixed frames 41. Compared with the prior art, the position of the substrate during rotation can always be kept consistent while the substrate is flipped. This not only enables the substrate to move synchronously with the bracket 411, preventing the substrate from falling during rotation, but also enables the position of the substrate to remain unchanged after flipping, preventing the position of the substrate from shifting, thereby facilitating the attachment of the polarizer and making the attachment accuracy of the polarizer more accurate.

[0047] Please refer to Figure 1 、 Figure 7 、 Figure 8 As shown, the flipping and positioning assembly includes positioning frames 412 symmetrically fixed at both ends of the bottom of the bracket 411. On the side of the positioning frames 412 facing the positioning plate 2, reset springs 414 are symmetrically fixedly connected. The other ends of the reset springs 414 are fixedly connected to positioning balls 415. On the opposite sides between the positioning plates 2, positioning grooves 5 are symmetrically formed respectively. The positioning balls 415 are adaptively fitted with the positioning grooves 5. A sliding rod 413 is fixedly installed inside the positioning balls 415, and the end of the sliding rod 413 away from the positioning balls 415 is slidably fitted inside the positioning frames 412.

[0048] The effects achieved by this embodiment are as follows: While the substrate rotates following the bracket 411, under the influence of the rotational external force, the positioning ball 415 will disengage from the inside of the positioning groove 5. When the substrate stops again and forms a perpendicular relationship with the positioning plate 2, the positioning ball 415 will be embedded in the inside of the positioning groove 5. Compared with the prior art, by setting the positioning connection relationship, the rotation of the rotating shaft 314 can be limited, and the substrate after rotation can be positioned synchronously, preventing the exposed surface of the substrate from being easily rotated by the rotating shaft 314 under the influence of external force during the process of attaching the polarizing film, resulting in the situation of substrate offset.

[0049] The complete usage steps and working principle of the above embodiment are as follows:

[0050] Before attaching the polarizing film, the knob 46 can be rotated to drive the threaded rod 45 to rotate on the fixed bracket 41. Synchronously, the linkage block 47 connected to the outer ring surface of the threaded rod 45 will move in the vertical axis direction under the drive of the thread, thereby increasing or decreasing the size of the side clamping area formed between the fixed plate 49 and the fixed bracket 41 to adapt to the side thickness of the substrate. When the side clamping area becomes larger after being adjusted by the movement of the fixed plate 49, the two sides of the substrate can be inserted between the fixed plate 49 and the fixed bracket 41, that is, within the side clamping area. At this time, since the bracket 411 is connected between the two fixed plates 49, the substrate will be placed on the bracket 411, and the bracket 411 will give the substrate an upward supporting force to make the substrate more stably installed between the two fixed brackets 41;

[0051] After the work of placing the substrate between the fixed brackets 41 is completed, the knob 46 can be rotated in the reverse direction to drive the fixed plate 49 to press downward towards the substrate to clamp and fix the substrate accordingly, so that the substrate can be firmly installed within the side clamping area formed between the fixed plate 49 and the fixed bracket 41;

[0052] After the substrate is placed and clamped, the exposed surface of the substrate can be attached with a polarizing film. After the exposed surface polarizing film is attached, the sleeve 313 can be rotated to drive the linkage shaft 312 to rotate accordingly on the mounting frame 311, thereby driving the main rod 310 connected at both ends to rotate synchronously. When the main rod 310 rotates around the linkage shaft 312, the linkage drives the linkage rod 39 to follow the movement. Through the following movement of the linkage rod 39, a moving force can be applied to the sleeve block 37. When the main rod 310 rotates toward the side away from the moving block 34, the moving block 34 can be driven to slide in the side plate 31 in the direction of the main rod 310 under the pull of the linkage rod 39. Since the lever 36 adapted to the groove 316 is installed on the moving block 34, when the moving block 34 moves When the lever 36 is in contact with the special-shaped plate 315, the lever 36 will follow the opening path of the groove 316 and enter the groove 316 in sequence, and follow the movement of the lever 36 to make the special-shaped plate 315 rotate accordingly at the upper end of the side plate 31. When the lever 36 is fully embedded in the groove 316, the moving block 34 is at the center of the side plate 31. At the same time, the main rod 310 is in a vertical state, and the sleeve 313 continues to rotate, so that the main rod 310 follows the rotation and eventually moves away from the moving block 34. When the linkage rod 39 and the main rod 310 are on the same axis, the lever 36 gradually breaks away from the contact with the groove 316, and driven by the lever 36, the special-shaped plate 315 continues to rotate. At this time, the moving block 34 moves to the end completely opposite to the end just now, and the special-shaped plate 315 is synchronously rotated to a final angle of 180 degrees.

[0053] When the special-shaped plate 315 rotates, the rotating shaft 314 installed at the center thereof rotates synchronously at the upper end of the side plate 31, and drives the fixing frame 41 to rotate synchronously, so that the substrate clamped between the two fixing frames 41 rotates accordingly. At this time, since the substrate also rotates 180 degrees, the exposed surface just now can be rotated and replaced with the other surface, so that the operator can attach polarizers to both sides of the substrate.

[0054] When the base 310 is used next time, the sleeve 313 can be rotated to rotate the main rod 310, and a pushing force is applied to the moving block 34 through the linkage rod 39 to push the moving block 34 back to the end away from the mounting bracket 311. The special-shaped plate 315 is moved by the lever 36 again to rotate 180 degrees, so that the clamped substrate can be turned over.

[0055] Since the moving block 34 is further provided with two cross bars 35 located obliquely below the lever 36, when the lever 36 is out of contact with the groove 316 and the moving block 34 continues to move, it can contact the side of the special-shaped plate 315, thereby correcting the rotation angle of the special-shaped plate 315 and making the stop angle of the special-shaped plate 315 more accurate;

[0056] When the fixing frame 41 rotates synchronously with the special-shaped plate 315, through the sliding connection between the arc-shaped block 43 and the annular groove 317, the fixing frame 41 can still slide on the side plate 31 with the rotating shaft 314 as the center, so as to prevent the fixing frame 41 from rotating and losing weight, provide a stable supporting force for the rotation process of the fixing frame 41, and make the rotation of the substrate more stable.

[0057] While the substrate is rotating, the bracket 411 will inevitably rotate accordingly. When the bracket 411 rotates, the angle of the positioning frame 412 deflects, causing the positioning ball 415 to disengage from the positioning groove 5. At this time, the reset spring 414 loses its force, pops the positioning ball 415 out continuously, and drives the sliding rod 413 to slide outward on the positioning frame 412. When the substrate is flipped 180 degrees, the positioning frame 412 returns to the balanced state. Through the extrusion of the wall of the positioning plate 2, the positioning ball 415 can be squeezed away from the positioning plate 2, and the sliding rod 413 is synchronously contracted. When the positioning ball 415 contacts the positioning groove 5, the external force of the reset spring 414 being squeezed disappears, and under the action of the elastic force, it is reset, popping the positioning ball 415 into the positioning groove 5, and the sliding rod 413 slides on the positioning frame 412 towards the adjacent positioning plate 2 synchronously, so as to prevent the positioning ball 415 from easily detaching during the process of attaching the polarizer. By setting the form of the positioning ball 415 being embedded in the positioning groove 5, the angle of the substrate after rotation can be fixed, and it will not easily deflect during the process of attaching the polarizer, thereby increasing the stability of the substrate.

[0058] The circuits and controls involved in the present invention are all prior arts and will not be elaborated here.
