Description

Technical Field

[0001] The present invention belongs to the technical field of liquid crystal filling, and in particular relates to a horizontal liquid crystal filling device and process for large-size LCDs. Background Art

[0002] The cell formation process precisely aligns the array substrate and color filter substrate to form a liquid crystal cell. After completing the cleaning, alignment layer coating, and rubbing steps, an appropriate amount of liquid crystal molecules is dripped into the LCD display area on the array substrate or color filter substrate (usually the color filter substrate) (this operation is also called liquid crystal infusion). Frame sealant is then applied to the corresponding display boundary area on the other substrate. The two substrates are then precisely aligned, one above the other, in a vacuum environment.

[0003] However, the above-mentioned liquid crystal perfusion method is not suitable for the manufacture of large-size LCDs. This is mainly because when the substrates are placed vertically, gravity will affect the applied border sealant, and liquid crystal molecules and border sealant need to be dripped on the two substrates separately. In addition, in the process of making the upper substrate coated with border sealant correspond to the lower substrate dripped with liquid crystal molecules, the two positions need to be precisely aligned, which is quite difficult and requires a high degree of accuracy of the device, increasing the complexity of the process. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a large-size LCD horizontal liquid crystal filling device and process for coating a sealing frame glue and pouring liquid crystal on the same substrate, and integrating the two operations at the same position to reduce the process complexity.

[0005] In order to solve the above technical problems, the present invention provides such a large-size LCD horizontal liquid crystal perfusion device, comprising a frame, a conveyor, an electric guide rail 1, a lifting frame 1, a supporting guide rail, an electric guide rail 2, an electric guide rail 3, a sliding frame, a turntable, a sealing nozzle, a liquid crystal nozzle and a driving assembly. A conveyor for conveying a color film substrate is installed on the upper side of the frame, and a vertically arranged electric guide rail 1 is installed on the upper left side of the frame. The slider of the electric guide rail 1 is connected to the lifting frame 1, and the left and right sides of the lifting frame 1 are respectively installed with a supporting guide rail and an electric guide rail 2. The slider of the electric guide rail 2 is installed with an electric guide rail 3 sliding on the supporting guide rail. The electric guide rail 3 is perpendicular to the electric guide rail 2, and the slider of the electric guide rail 3 is connected to the sliding frame. There are two rotating turntables facing each other front and back on the sliding frame, and a sealing nozzle and two liquid crystal nozzles are respectively installed on the two turntables. The nozzle direction of the liquid crystal nozzle and the nozzle direction of the sealing nozzle are staggered, and the sliding frame is provided with a driving assembly for driving the two turntables to rotate.

[0006] Preferably, the driving assembly includes a resistance rod, a cylinder and a push-pull frame. The two turntables are connected to each other on one side with a resistance rod, and the resistance rod is located at the eccentric point of the turntable. A cylinder is installed on one side of the sliding frame. The piston of the cylinder is connected to a push-pull frame surrounding the two resistance rods, and a vertical groove is opened on the push-pull frame for the resistance rod to slide.

[0007] Preferably, it also includes an electric screw rod and a limit plate. The electric screw rod is installed on the lifting frame. The screw rod in the electric screw rod is a bidirectional screw rod. The electric screw rod is threadedly connected to two limit plates opposite to each other on the left and right.

[0008] Preferably, it also includes a bracket and a heater. Two front and rear opposite brackets are connected to the upper right side of the frame. A heater is installed between the upper sides of the two brackets and located directly above the conveyor. The heater heats the sealing frame glue coated on the color film substrate and the injected liquid crystal.

[0009] Preferably, it also includes an electric guide rail four, a lifting frame two, an electric screw rod two and a limit shovel. A predetermined distance is left between the heater and the conveyor. Two front and rear electric guide rails four are installed on the upper right side of the frame. The front and rear electric guide rails four are respectively located on the front and rear sides of the conveyor. The slider of the electric guide rail four is connected to the lifting frame two. The lifting frame two is provided with a mounting frame. The mounting frame is installed with an electric screw rod two. The screw rod in the electric screw rod two is a bidirectional screw rod. Two left and right relative limit shovels are threadedly connected to the electric screw rod two.

[0010] Preferably, it also includes a spring, a resistance block and an extrusion plate. The mounting frame is slidably arranged on the lifting frame 2. Two left and right opposite springs located in the lifting frame are connected between the mounting frame and the lifting frame 2. The right end of the mounting frame is connected to the resistance block. One side of the bracket is connected to an extrusion plate suitable for extruding the resistance block, and the extrusion plate has multiple protrusions.

[0011] Preferably, a positioning push plate is also included. At least two positioning push plates are connected to the conveyor belt of the conveyor. The positioning push plates are used to push the color film substrate. When one positioning push plate pushes the color film substrate to be injected with liquid crystal to the bottom of the sealing nozzle, the other positioning push plate pushes the color film substrate injected with liquid crystal to the bottom of the heater.

[0012] Preferably, it also includes pillars and blow pipes. Two front and rear opposing pillars are connected to the upper left side of the frame. A blow pipe located above the conveyor is installed between the two pillars. The nozzle of the blow pipe faces away from the sealing nozzle, and the sealing nozzle is located between the blow pipe and the heater.

[0013] The present invention also provides a pouring process according to the above-mentioned large-size LCD horizontal liquid crystal pouring device, comprising:

[0014] S1) The conveyor conveys the color film substrate from left to right to below the sealing nozzle, and the electric guide rails 1, 2 and 3 are controlled to adjust the position of the sliding frame, thereby adjusting the movement of the sealing nozzle to apply the sealing frame glue to the color film substrate;

[0015] S2) After the sealing glue nozzle has applied the sealing glue, the liquid crystal nozzle is used to pour liquid crystal into the sealing glue on the color film substrate, and the liquid crystal nozzle and the sealing glue nozzle are both arranged on the sliding frame by rotating the turntable;

[0016] S3) Controlling the driving assembly to drive the two turntables to respectively drive the liquid crystal nozzle and the sealing nozzle to rotate, so as to automatically rotate the liquid crystal nozzle and the sealing nozzle alternately.

[0017] The present invention overcomes the shortcomings of the prior art and has the following beneficial effects:

[0018] 1. The sealing nozzle and the liquid crystal nozzle are automatically and alternately used on the sliding frame to integrate the functions of sealing glue coating and liquid crystal injection in one place, which not only reduces the complexity of the structure, but also eliminates unnecessary process steps, thereby improving work efficiency.

[0019] 2. When the sealing nozzle is close to the color film substrate, the two limit plates are also moved down to both sides of the color film substrate. At this time, the two limit plates are driven close to each other, which can not only stabilize the color film substrate, but also align the color film substrate to ensure the working effect of the sealing nozzle and the liquid crystal nozzle.

[0020] 3. When the color film substrate moves off the conveyor and approaches the heater for heating, the resistance block and the extrusion plate are used to automatically and synchronously shake the color film substrate, accelerating the curing process of the frame sealant, facilitating the subsequent alignment of the array substrate and the color film substrate, and enabling the liquid crystal molecules on the color film substrate to be arranged more quickly and neatly, thereby improving automation and synchronization.

[0034] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0035] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0036] Large size LCD horizontal liquid crystal filling device, such as Figure 1-Figure 3 As shown, it includes a frame 1, a conveyor 2, an electric guide rail 1 31, a lifting frame 1 32, a support rail 33, an electric guide rail 2 34, an electric guide rail 35, a sliding frame 36, a turntable 37, a sealing nozzle 38, a liquid crystal nozzle 39 and a drive component 4. The upper side of the frame 1 is equipped with a conveyor 2 for conveying the color film substrate from left to right. The upper left side of the frame 1 is equipped with a vertically arranged electric guide rail 1 31. The slider of the electric guide rail 1 31 is connected to the lifting frame 1 32. The left and right sides of the lifting frame 1 32 are respectively equipped with a support rail 33 and an electric guide rail 2 34. Controlling the electric guide rail 1 31 can drive the lifting frame belt The electric guide rail 2 34 moves up and down, and the slider of the electric guide rail 2 34 is equipped with an electric guide rail 35 that slides on the support guide rail 33. The electric guide rail 35 is perpendicular to the electric guide rail 2 34. The slider of the electric guide rail 35 is connected to the sliding frame 36. Controlling the electric guide rail 2 34 can drive the electric guide rail 35 to drive the sliding frame 36 to move forward and backward. Controlling the electric guide rail 35 drives the sliding frame 36 to move left and right, so as to facilitate the adjustment of the up and down, front and back and left and right positions of the sliding frame 36. There are two front and back opposite turntables 37 rotating on the sliding frame 36. The two turntables 37 are respectively equipped with a plate for coating and sealing the color film substrate. The sealing nozzle 38 of the frame glue and the two liquid crystal nozzles 39 for injecting liquid crystal into the area formed by the sealing frame glue on the color film substrate are arranged in an alternating direction. The nozzle direction of the liquid crystal nozzle 39 is staggered with the nozzle direction of the sealing nozzle 38. The sliding frame 36 is provided with a driving component 4 for driving the two turntables 37 to rotate. Initially, the nozzle of the sealing nozzle 38 is facing downward and the liquid crystal nozzle 39 is in a retracted state. When the conveyor 2 moves the color film substrate to the right below the sealing nozzle 38, the position of the sliding frame 36 is adjusted so that the sliding frame 36 first drives the sealing nozzle 38 to move down close to the color film substrate, and then moves the sealing nozzle 38 to the set degree. The surface of the color filter substrate is coated with sealing glue. After the sealing glue is applied, the driving component 4 is controlled to drive the turntable 37 to rotate so that the nozzle of the liquid crystal nozzle 39 is facing. At this time, the sealing glue nozzle 38 is in the retracted state, and then the liquid crystal nozzle 39 can be used to inject liquid crystal into the area formed by the sealing glue on the color filter substrate, thereby integrating the functions of sealing glue coating and liquid crystal injection in one place, which not only reduces the complexity of the structure, but also eliminates unnecessary process steps, thereby improving work efficiency; in addition, since the liquid crystal has been injected into the area formed by the sealing glue, it is convenient for the subsequent precise alignment operation of the array substrate and the color filter substrate.

[0037] like Figure 3-Figure 6 As shown, the driving assembly 4 includes a resistance rod 41, a cylinder 42 and a push-pull frame 43. The two turntables 37 are connected to each other on one side thereof. The resistance rod 41 is located at the eccentric part of the turntable 37. The turntable 37 is driven to rotate by the resistance rod 41, thereby driving the sealing nozzle 38 and the liquid crystal nozzle 39 to be used alternately. A cylinder 42 is installed on one side of the sliding frame 36. The piston of the cylinder 42 is connected to the push-pull frame 43 surrounding the two resistance rods 41. The push-pull frame 43 is provided with a vertical slot for the resistance rod 41 to slide. Initially, the cylinder 42 is in an extended state. The piston of the control cylinder 42 is retracted to drive the sliding frame 36 to move right. The sliding frame 36 will squeeze the resistance rod 41 to drive the turntable 37 to rotate, thereby automatically alternating the sealing nozzle 38 and the liquid crystal nozzle 39.

[0038] like Figure 7 As shown, it also includes an electric screw rod 51 and a limit plate 52. The electric screw rod 51 is installed on the lifting frame 32. The screw rod in the electric screw rod 51 is a bidirectional screw rod. Two left and right opposite limit plates 52 are threadedly connected to the electric screw rod 51. When the electric guide rail 31 drives the lifting frame to move downward and liquid crystal perfusion is required for the color film substrate on the conveyor 2, the lifting frame will drive the left and right limit plates 52 to move downward to the left and right sides of the color film substrate respectively. At this time, the electric screw rod 51 is controlled to drive the two limit plates 52 to approach each other, so as to stabilize the color film substrate and align the color film substrate to ensure the working effect of the sealing nozzle 38 and the liquid crystal nozzle 39.

[0039] like Figure 1 and Figure 8 As shown, it also includes a bracket 61 and a heater 62. Two brackets 61 facing each other are connected to the upper right side of the frame 1. A heater 62 is installed between the upper sides of the two brackets 61 and is located directly above the conveyor 2. The heater 62 heats the sealing frame glue coated on the color filter substrate and the injected liquid crystal. In this way, the temperature can be used to make the bubbles inside the liquid crystal escape and burst, and the curing process of the sealing frame glue can be accelerated, which is convenient for the subsequent alignment of the array substrate and the color filter substrate.

[0040] like Figure 1 、 Figure 8 、 Figure 9 and Figure 10As shown, it also includes an electric guide rail 4 71, a lifting frame 2 72, an electric screw rod 2 74 and a limiting shovel 75. A predetermined distance is left between the heater 62 and the conveyor 2. The predetermined distance prevents the heater 62 from affecting the conveyor 2. Two front and rear electric guide rails 4 71 are installed on the upper right side of the frame 1. The front and rear electric guide rails 4 71 are respectively located on the front and rear sides of the conveyor 2. The slider of the electric guide rail 4 71 is connected to the lifting frame 2 72. Controlling the electric guide rail 4 71 can drive the lifting frame 2 72 to move up and down. A mounting frame 73 is provided on the lifting frame 2. An electric screw rod 2 74 is installed on the mounting frame 73. The screw rod in the electric screw rod 2 74 is a bidirectional screw rod. There are two left and right opposite screw rods on the electric screw rod 2 74. Limiting shovel 75, when conveyor 2 moves the color film substrate coated with sealing frame glue and infused with liquid crystal to the right below heater 62, control electric guide rail four 71 to drive lifting frame two 72 to drive installation frame 73 to move down, and installation frame 73 will drive the left and right limiting shovels 75 to move down to the left and right sides of the color film substrate respectively. At this time, control electric screw rod two 74 to drive the two limiting shovels 75 to approach each other, and the limiting shovel 75 will scoop up the color film substrate and stabilize it, and then control electric guide rail four 71 to drive lifting frame two 72 to drive installation frame 73 to move up, so that the color film substrate is closer to heater 62 for heating, thereby avoiding the heater 62 affecting conveyor 2 and ensuring the heating operation of the sealing frame glue coated on the color film substrate and the liquid crystal infused.

[0041] like Figure 8 、 Figure 10 and Figure 11 As shown, it also includes a spring 81, a resistance block 82 and an extrusion plate 83. The installation frame 73 is slidably arranged on the lifting frame 72. Two springs 81 located in the lifting frame are connected between the installation frame 73 and the lifting frame 72. The right end of the installation frame 73 is connected to the resistance block 82. One side of the bracket 61 is connected to an extrusion plate 83 suitable for extruding the resistance block 82. The extrusion plate 83 has a plurality of protrusions. When the installation frame 73 moves up and drives the color film substrate to leave the conveyor 2 and approach the heater 62 through the limiting shovel 75, the installation frame 73 will also drive the resistance block 82 to move up and contact the protrusions on the extrusion plate 83. The protrusions will squeeze the resistance block 82. Then, the installation frame 73 will drive the color film substrate to shake left and right through the limiting shovel 75 under the action of the spring 81, so that the liquid crystal molecules on the color film substrate can be arranged more quickly and neatly, and the color film substrate will shake automatically and synchronously when it moves up and leaves the conveyor 2, which not only improves automation and synchronization, but also avoids friction interference between the color film substrate and the conveyor 2.

[0042] like Figure 1 and Figure 12As shown, a positioning push plate 21 is also included. At least two positioning push plates 21 are connected to the conveyor belt of the conveyor 2. The positioning push plates 21 are used to push the color film substrate. When the conveyor belt in the conveyor 2 transports the color film substrate from left to right, when one positioning push plate 21 pushes the color film substrate to be infused with liquid crystal to the bottom of the sealing nozzle 38, the other positioning push plate 21 pushes the color film substrate infused with liquid crystal to the bottom of the heater 62. In this way, the two color film substrates can be processed synchronously. When the color film substrate to be infused with liquid crystal is undergoing the liquid crystal infusion operation, the color film substrate infused with liquid crystal can be shaken and heated. The various steps are interrelated and coordinated with each other, thereby improving work efficiency.

[0043] like Figure 12 As shown, it also includes a support 11 and a blow pipe 12. Two front-to-rear opposing supports 11 are connected to the upper left side of the frame 1. A blow pipe 12 is installed between the two supports 11 and is located above the conveyor 2. The nozzle of the blow pipe 12 is facing away from the sealing nozzle 38. The sealing nozzle 38 is located between the blow pipe 12 and the heater 62. When the color filter substrate to be filled with liquid crystal is placed on the left end of the conveyor 2 for transportation, the blow pipe 12 is connected to nitrogen to spray the upper side of the color filter substrate, so as to remove impurities such as dust on the color filter substrate in advance before filling the liquid crystal, thereby ensuring the cleanliness of the surface of the color filter substrate.

[0044] The pouring process of the large-size LCD horizontal liquid crystal pouring device includes: S1) causing the conveyor 2 to convey the color filter substrate from left to right to below the sealing nozzle 38, and controlling the electric guide rail 1 31, the electric guide rail 2 34 and the electric guide rail 3 35 to adjust the position of the sliding frame 36, thereby adjusting the movement of the sealing nozzle 38 to apply the sealing frame glue to the color filter substrate;

[0045] S2) After the sealant nozzle 38 has applied the sealant, the liquid crystal nozzle 39 is used to inject liquid crystal into the sealant on the color filter substrate. The liquid crystal nozzle 39 and the sealant nozzle 38 are both rotatably mounted on the sliding frame 36 via a turntable 37, thereby integrating the functions of sealant application and liquid crystal injection into one place, which not only reduces the complexity of the structure but also eliminates unnecessary process steps.

[0046] S3) Control the driving assembly 4 to drive the two turntables 37 to respectively drive the liquid crystal nozzle 39 and the sealing nozzle 38 to rotate, thereby automatically and alternately using the liquid crystal nozzle 39 and the sealing nozzle 38 to rotate, with a high degree of automation.

[0047] Obviously, the embodiments described above are only part of the embodiments of the present invention, rather than all the embodiments. They only express the preferred implementation methods of the present invention and the description is relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention.

[0048] It should be pointed out that, for ordinary technicians in this field, several variations, increases and decreases in quantity, improvements and substitutions can be made without departing from the concept of the present invention. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.
