Description

Technical Field

[0001] The utility model relates to the technical field of crystal grain processing, and more specifically, to a laminating device for a full-spectrum LCD liquid crystal screen. Background Art

[0002] During the production process of LCD screens, crystals are placed on the LCD panel to control the orientation and arrangement of the liquid crystals to ensure the normal display function of the screen. These crystals are usually made through a precise manufacturing process, with very fine structures and sizes, and play a vital role in the performance and display effect of the LCD screen.

[0003] Currently, in the production process, the die (single light source chip) has been pre-placed in a die box, and then this die box is used as the source of loading, which means that the die in the die box is fed into the production equipment. There are multiple process steps in the front section of the die box loading. The die needs to be accurately positioned and corrected to ensure that they are properly aligned with the LCD screen. At the same time, defect detection is required for unqualified die, and workers need to manually screen out defective products. The low integration of multiple process steps leads to reduced production efficiency, large equipment footprint, and increased production time and cost. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a laminating device for a full-spectrum LCD screen, which has the advantages of reducing processing links and lowering costs.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a laminating device for a full-spectrum LCD screen comprises a mounting frame, a plurality of conveying rollers are rotatably mounted on both ends of the inner side of the mounting frame, the conveying rollers are connected by a belt drive, a quality detector is fixedly mounted on one side of the mounting frame to perform quality inspection on the grains; a transfer mechanism is mounted on the other side of the mounting frame corresponding to the quality detector; wherein a press-fitting mechanism is integrated on the outer side of the mounting frame, and the press-fitting mechanism is located below the transfer mechanism.

[0006] As a preferred technical solution of the utility model, a first motor is fixedly installed on the outer side of the mounting frame, and the first motor is connected to the conveying roller and can drive the conveying roller to rotate.

[0007] As a preferred technical solution of the utility model, an incomplete gear is fixedly installed on the output shaft of the first motor, and a transmission gear is coaxially fixedly installed on one end of one of the conveying rollers; wherein, a tooth portion is partially provided on the outer periphery of the incomplete gear, and the transmission gear is located on the outer side of the mounting frame and intermittently meshes with the incomplete gear, so that the conveying roller is intermittently transmitted.

[0008] By starting the first motor, the incomplete gear rotates. When the incomplete gear meshes with the transmission gear, the transmission gear rotates a certain angle; when the incomplete gear disengages from the transmission gear, the transmission gear stops rotating, causing the transmission gear to rotate periodically, which in turn causes the corresponding conveying roller to rotate periodically, thereby causing the belt to translate periodically, which causes the belt to transport the grains periodically for a certain distance. Each time the belt stops transporting, it transports a grain to the position of the quality detector, and the quality detector can detect the grains. If the quality of the grains is qualified, the grains will be transferred to the pressing mechanism through the transfer mechanism; if the quality of the grains is unqualified, the belt will continue to transport them until they are transported to the corresponding collection device. This process can realize the quality inspection of the grains one by one, thereby realizing the automatic selection of the grains, greatly improving the efficiency of grain selection.

[0009] As a preferred technical solution of the utility model, the transfer mechanism includes a fixed plate, which is fixedly installed on the outside of the mounting frame, a second motor is fixedly installed on the bottom of the fixed plate, and a rotating plate is fixedly installed on the output shaft of the second motor.

[0011] As a preferred technical solution of the utility model, an air guide hose is fixedly installed on the outer edge of the top of the suction cup, and the air guide hose is connected to the inside of the suction cup. An air pump is fixedly installed on the top of the rotating plate, and the outlet end of the air pump is connected to the top of the air guide hose.

[0012] As a preferred technical solution of the utility model, the press-fitting mechanism includes a fixing frame, and the fixing frame is fixedly installed on the outer side of the mounting frame.

[0013] As a preferred technical solution of the utility model, two parallel guide rails are fixedly installed on the top of the fixing frame, and a positioning seat is slidably installed on the top of the guide rails.

[0014] As a preferred technical solution of the utility model, a third cylinder is fixedly installed on one end of the top of the fixing frame, and a pressure plate is fixedly installed on the output end of the third cylinder, and the pressure plate can cooperate with the positioning seat.

[0015] By controlling the third cylinder to make the positioning seat slide along the guide rail to the bottom of the pressure plate, and then controlling the third cylinder to make the pressure plate translate downward to contact the crystal grain and apply pressure to it, the crystal grain and the LCD screen port are pressed into one. The whole process can realize the transportation, transfer and pressing of the crystal grain, reduce the intermediate links, and greatly reduce the production cost.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 4 shown, the present utility model provides a laminating device for a full-spectrum LCD liquid crystal screen, including a mounting frame 1. The mounting frame 1 is a main support structure, presenting a "U" shape, and its bottom can be used to fix the entire laminating device to provide stable support.

[0027] Further, both ends of the inner side of the mounting frame 1 are rotatably installed with conveying rollers 2. The two conveying rollers 2 are传动连接 by a belt 3. The conveying rollers 2 can rotate freely and connect the two conveying rollers 2 as a transmission medium, enabling the crystal grains to move smoothly between the two conveying rollers 2. The belt 3 can support and convey the crystal grains to ensure the stability and accuracy of the crystal grains during the conveying process.

[0028] A first motor 4 is fixedly installed on the outer side of the mounting frame 1. The output shaft of the first motor 4 is fixedly installed with an incomplete gear 5. One end of one of the conveying rollers 2 is coaxially fixedly installed with a transmission gear 6. The transmission gear 6 is located outside the mounting frame 1 and intermittently meshes with the incomplete gear 5.

[0029] It should be noted that there is an error in the original text where "传动连接" is used without a clear description. I translated it as "传动连接" for now, but it might need to be corrected to a more specific term like "driven connection" or something more appropriate depending on the actual meaning.Furthermore, a quality detector 7 is fixedly installed on one side of the mounting frame 1 to perform quality inspection on the grains; a transfer mechanism 8 is installed on the other side of the mounting frame 1, and a pressing mechanism 9 is installed on the outer side of the mounting frame 1, and the pressing mechanism 9 is located below the transfer mechanism 8; the incomplete gear 5 is rotated by starting the first motor 4, and when the incomplete gear 5 is engaged with the transmission gear 6, the transmission gear 6 will rotate a certain angle; when the incomplete gear 5 is disengaged from the transmission gear 6, the transmission gear 6 will stop rotating, so that the transmission gear 6 rotates periodically, and the corresponding conveying roller 2 rotates periodically. The belt 3 moves, and then the belt 3 is periodically translated, which makes the belt 3 transport the grains periodically for a certain distance. Each time the belt 3 stops transporting, it just transports a grain to the position of the quality detector 7, and the quality detector 7 can detect the grains. If the grain quality is qualified, the grain will be transferred to the pressing mechanism 9 through the transfer mechanism 8; if the grain quality is unqualified, the belt 3 will continue to transport it until it is transported to the corresponding collection device. This process can realize the quality inspection of the grains one by one, thereby realizing the automatic selection of the grains, greatly improving the selection efficiency of the grains. Through the quality detector 7, the quality inspection of each grain can be carried out, and the grains with qualified quality can be quickly and accurately identified. The unqualified grains will be automatically transferred to the collection device, avoiding the tediousness and errors of manual screening. And because the grains are transported periodically, each transportation is subject to quality inspection, which greatly improves the screening efficiency of the grains. In addition, the automatic collection of unqualified grains also reduces the workload of subsequent processing, which is suitable for large-scale and high-efficiency production environments, and can quickly and accurately process a large number of grains.

[0030] Continue reading Figure 3 The transfer mechanism 8 includes a fixed plate 81, which is fixedly mounted on the outside of the mounting frame 1, a second motor 82 is fixedly mounted on the bottom of the fixed plate 81, a rotating plate 83 is fixedly mounted on the output shaft of the second motor 82, a first cylinder 84 is fixedly mounted on one end of the rotating plate 83, and a suction cup 85 is fixedly mounted on the output end of the first cylinder 84; an air guide hose 86 is fixedly mounted on the outer edge of the top of the suction cup 85, and the air guide hose 86 is communicated with the inside of the suction cup 85, an air pump 87 is fixedly mounted on the top of the rotating plate 83, and the outlet end of the air pump 87 is connected to the top of the air guide hose 86.

[0031] Specifically, the fixed plate 81 is fixedly mounted on the outside of the mounting frame 1 to provide stable support for the transfer mechanism. The second motor 82 is fixed to the bottom of the fixed plate 81 to drive the subsequent rotating plate 83; the first cylinder 84 enables the transfer mechanism to have better adjustment and adaptability, the air hose 86 is connected to the inside of the suction cup 85 to transmit gas, and the air pump 87 is installed on the top of the rotating plate 83, and its outlet end is connected to the top of the air hose 86 to provide air pressure so that the suction cup 85 can absorb the grains. The combination of the second motor 82 and the air pump 87 enables the transfer mechanism 8 to work automatically and continuously without human intervention.

[0032] It can be understood that when the quality detector 7 detects that one of the grains is qualified, a control signal will be issued, and the suction cup 85 will be moved downward to contact the grain and apply pressure to it by controlling the first cylinder 84. When pressure is applied, the air between the suction cup 85 and the grain is discharged, which makes the suction cup 85 in a negative pressure state, so that the grain is adsorbed on the suction cup 85, and then the first cylinder 84 is controlled to make the suction cup 85 suck the grain upward, and then the second motor 82 is started to make the rotating plate 83 rotate 90 degrees, so that the suction cup 85 transfers the grain to the positioning seat 93 and aligns it with the LCD port, and finally the air pump 87 is started to guide the air guide hose 86 into the suction cup 85, which increases the air pressure inside the suction cup 85, so that the grain is separated from the suction cup 85, and then the grain and the LCD port are overlapped, realizing automatic transfer and positioning of the grain, reducing manual labor; the structure is compact and the work process is smooth, ensuring efficient and stable grain transportation and bonding process.

[0033] Continue reading Figure 4 The pressing mechanism 9 includes a fixing frame 91, which is fixedly mounted on the outside of the mounting frame 1. Two parallel guide rails 92 are fixedly mounted on the top of the fixing frame 91, and a positioning seat 93 is slidably mounted on the top of the guide rail 92; a third cylinder 95 is fixedly mounted on one end of the top of the fixing frame 91, and a pressing plate 96 is fixedly mounted on the output end of the third cylinder 95, and the pressing plate 96 can cooperate with the positioning seat 93.

[0034] After the crystal grain is aligned with the LCD port on the positioning seat 93, the positioning seat 93 is controlled to slide along the guide rail 92 to the bottom of the pressure plate 96, and then the third cylinder 95 is controlled to make the pressure plate 96 translate downward to contact the crystal grain and apply pressure to it, so that the crystal grain and the LCD port are pressed into one. The whole process can realize the transportation, transfer and pressing of the crystal grain, reduce the intermediate links, and greatly reduce the production cost.
