Description

Technical Field

[0001] This utility model relates to the field of segmentation equipment technology, and in particular to a liquid crystal display screen segmentation machine. Background Technology

[0002] Liquid crystal displays (LCDs) are ultra-thin glass composed of a glass substrate, a protective film, and a liquid crystal layer. Due to the special nature of the glass used in LCDs, laser cutting machines are typically used to cut them. Laser cutting machines utilize the heat generated by the laser to induce cracks and fractures in the glass, thus dividing the display screen. During the cutting process, the material is rapidly heated by the laser beam and then quickly cooled by convection and heat conduction. This causes an imbalance in the distribution of thermal stress within the material, leading to uncontrollable cracking and affecting the cutting quality. Numerical simulation of the thermal stress field during laser cutting is crucial for understanding the dynamic distribution of the thermal stress field during the cutting process and optimizing the cutting technology.

[0003] Traditional LCD screen cutting equipment requires a transport device to place the LCD screens one by one under the cutting device for single-pass cutting. After each cut, the screen is removed before the next screen is placed on the cutting device for the next cut. This method reduces cutting efficiency and increases labor costs due to the need for manual handling of the LCD screens. Utility Model Content

[0048] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0049] like Figures 1 to 6 As shown in the figure, the present invention includes a roller conveyor 1 and a pre-cutting cleaning device 2, a pre-cutting stop device 3, a dividing device 4, a dividing stop device 5, and a post-cutting cleaning device 6, which are sequentially installed on the roller conveyor 1 along the X direction.

[0050] The roller conveyor 1 is arranged along the X direction and includes a number of conveying rollers 11 arranged at equal intervals along the X direction. The roller conveyor 1 is used to transport the LCD screen 7 to move sequentially along the X direction.

[0051] In this application, the pre-cutting cleaning device 2 is used to clean the surface of the liquid crystal display screen 7 before cutting, and the post-cutting cleaning device 6 is used to clean the surface of the liquid crystal display screen 7 after cutting; the pre-cutting stop device 3 is used to block or release the liquid crystal display screen 7 in the X direction before cutting, and the cutting stop device 5 is used to block or release the liquid crystal display screen 7 to be cut in the X direction; the cutting device 4 includes a cutting moving mechanism 41 and a cutting mechanism 42 installed at its moving end, and the cutting moving mechanism 41 drives the cutting mechanism 42 to cut the liquid crystal display screen 7 at least once in the Y direction.

[0052] During the process of conveying the LCD screen 7 by the roller conveyor 1, the LCD screen 7 can be processed sequentially by the pre-cutting cleaning device 2, the pre-cutting stop device 3, the dividing device 4, the dividing stop device 5, and the post-cutting cleaning device 6, which can meet the need for continuous processing, improve processing efficiency and reduce labor costs. Moreover, the LCD screen 7 can be cleaned before and after dividing, which can improve the cleanliness of the screen surface before dividing without affecting the dividing quality, and also improve the cleanliness of the screen surface after dividing, so as not to scratch the screen surface during handling, thus improving product quality.

[0053] In this application, the pre-cutting cleaning device 2 and the post-cutting cleaning device 6 have the same structure. The pre-cutting cleaning device 2 includes an outer protective cover 21, an inner protective cover 22, a cleaning brush roller 23, and at least one high-pressure air blowing pipe 24. A suction pipe 25 is fixedly installed on the outer wall of the outer protective cover 21, and the suction pipe 25 communicates with the inner cavity of the outer protective cover 21. The inner protective cover 22 is located inside the outer protective cover 21 and forms an upward channel with it. The cleaning brush roller 23 is driven and connected to a cleaning power component (not shown in the figure). The cleaning brush roller 23 is arranged along the Y direction and rotatably installed in the inner cavity of the inner protective cover 22. The high-pressure air blowing pipe 24 is located in the inner cavity of the inner protective cover 22, in front of and / or behind the cleaning brush roller 23. The high-pressure air blowing pipe 24 is used to blow high-pressure airflow, which impacts the screen surface of the liquid crystal display 7, facilitating the cleaning brush roller 23 to clean the screen surface.

[0054] After the high-pressure airflow from the outside impacts the screen of the LCD display 7, the airflow carries the debris and dust from the screen through the upward channel between the inner protective cover 22 and the outer protective cover 21 and is discharged to the outside through the suction tube 25, thus completing the cleaning operation of the screen.

[0055] The pre-cutting stop device 3 and the dividing stop device 5 have the same structure; the pre-cutting stop device 3 includes a stop mounting plate 31, a stop cylinder 32, a stop horizontal plate 33, and several stop components 34. Among them, the stop mounting plate 31 is installed on the roller conveyor 1 and located below the conveying roller 11, the stop cylinder 32 is installed on the stop mounting plate 31, the stop horizontal plate 33 is installed on the piston rod of the stop cylinder 32, and the stop components 34 are installed on the stop horizontal plate 33 in an adjustable position along the Y direction, and the stop components 34 are located between two adjacent conveying rollers 11.

[0056] When the dividing device 4 divides the liquid crystal display screen 7, the downstream liquid crystal display screen 7 is blocked by the cutting stop device 3 to avoid affecting the dividing device 4; at the same time, the dividing stop device 5 can also block the liquid crystal display screen 7 so that the dividing device 4 can divide it.

[0057] The dividing moving mechanism 41 includes an X-axis linear slide 411, a Y-axis linear slide 412, and a Z-axis linear slide 413. The X-axis linear slide 411 is mounted on the roller conveyor 1, the Y-axis linear slide 412 is mounted on the moving end of the X-axis linear slide 411, the Z-axis linear slide 413 is mounted on the moving end of the Y-axis linear slide 412, and the cutting mechanism 42 is mounted on the moving end of the Z-axis linear slide 413.

[0058] The cutting mechanism 42 includes a cutting mounting plate 421 disposed on the moving end of the Z-axis linear slide 413. A laser cutting head 422 and a blowing nozzle 423 are mounted on the cutting mounting plate 421. The blowing nozzle 423 is connected to an external high-pressure air source for blowing away debris and dust generated during the cutting process.

[0059] In order to improve the dividing accuracy of the LCD screen 7 by the dividing device 4 and improve product quality, a dividing positioning device 8 is installed on the roller conveyor 1. The dividing positioning device 8 is installed below the conveyor roller 11 and corresponds to the position of the dividing device 4. The dividing positioning device 8 is used to clamp and position the LCD screen 7 to be divided in the Y direction.

[0060] The segmentation and positioning device 8 includes a positioning mounting plate 81 and two clamping components 82. The positioning mounting plate 81 is mounted on the roller conveyor 1 and located below the conveying roller 11. The two clamping components 82 are mounted on the positioning mounting plate 81 along the X direction. The two clamping components 82 have the same structure and each includes two clamping cylinders 821 arranged opposite each other along the Y direction. A clamping plate 822 is mounted on the piston rod of the clamping cylinder 821. The clamping plate 822 is located between two adjacent conveying rollers 11.

[0061] When fixing the LCD screen 7 in the Y direction, the two clamping cylinders 821 move relative to each other to push the clamping plate 822, causing the two clamping plates 822 to move together toward the LCD screen 7, thus clamping the LCD screen 7 together.

[0062] Preferably, the clamping plate 822 is provided with a guide slope 823 and a clamping groove 824, and a buffer pad 825 is adhered to the bottom of the clamping groove 824. When the clamping plate 822 abuts against the LCD screen 7, the LCD screen 7 can slide upward along the slope of the guide slope 823 under its action, thereby separating the LCD screen 7 from the conveying roller 11, so that the debris and dust generated during cutting can fall between the two conveying rollers 11, and at the same time, the conveying rollers 11 will not affect the cutting. The LCD screen 7 slides upward until it slides into the clamping groove 824, where it is fixed in position to prevent further upward movement, and the buffer pad 825 is provided to cushion its sides and prevent impact, thereby enhancing stability and safety.

[0063] In use, this application involves placing the LCD screen 7 on the roller conveyor 1, and then having the pre-cutting cleaning device 2, pre-cutting stop device 3, dividing device 4, dividing stop device 5, and post-cutting cleaning device 6 work together to complete the continuous dividing of the LCD screen 7. This replaces the traditional method of placing the LCD screen 7 piece by piece under the cutting device for single-cutting, improving dividing efficiency, reducing labor costs, and cleaning up the debris and dust generated during dividing, thus improving the cleanliness of the screen surface.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
