Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal screens, and in particular to a drying device for dispensing glue on liquid crystal screens. Background Art

[0002] Liquid crystal display (LCD) is a type of flat-panel display. It is used for screen displays on televisions and computers. The advantages of this display are low power consumption, small size, and low radiation. Gluing is a process, also known as gluing, coating, filling, or dripping, which involves applying, encapsulating, or dripping electronic glue, oil, or other liquids onto a product to achieve adhesion, encapsulation, insulation, fixation, and a smooth surface. During the LCD production process, glue is used to secure the LCD to the outer cover glass. After gluing is completed, a drying device is required to dry the glued areas on the LCD to secure the LCD to the cover glass. Therefore, a drying device is required.

[0003] The utility model with publication number CN 213079014 U discloses a drying device for dispensing glue on liquid crystal screens, including a drying chamber and a connecting rod. The inner wall of the drying chamber is provided with a heating tube, and support columns are fixed at both ends of the drying chamber. A placement box is installed at the bottom of the drying chamber, and screws are fixed between the placement box and the drying chamber. In the above application document, the drying chamber, connecting rod and other components cooperate with each other, making it difficult to achieve reciprocating linear motion of the push plate, resulting in the LCD screen being unable to be clamped and positioned, making the LCD screen unable to move away from the filter port of the filter plate, causing the LCD screen to be damaged by high temperature during the drying process, which needs to be improved.

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 to 5As shown, this embodiment proposes a drying device for dispensing glue for liquid crystal screens, including a base 1, a filter plate 2 is fixedly connected to the top of the base 1, a shell 3 is fixedly connected to the top of the base 1, and a positioning device 4 is provided on the inner wall of the shell 3; the positioning device 4 includes a motor 41, the motor 41 is fixed through the inner wall of the shell 3, the end of the output shaft of the motor 41 is fixedly connected to a reciprocating screw 42, the circumferential surface of the reciprocating screw 42 is threadedly connected to a reciprocating wire sleeve 43, the circumferential surface of the reciprocating wire sleeve 43 is fixedly connected to a fixed plate 44, and the front side of the fixed plate 44 is penetrated by a rotating shaft 45. The circumferential surface of the rotating shaft 45 is fixedly connected to a force-bearing rod 46. The end of the force-bearing rod 46 away from the rotating shaft 45 is fixedly connected to a rotating rod 47. The circumferential surface of the rotating rod 47 is penetrated by a connecting plate 48. The bottom of the connecting plate 48 is fixedly connected to a force-bearing block 49. The side of the force-bearing block 49 is fixedly connected to a push plate 410. A chute 411 is provided on the top of the filter plate 2. A telescopic rod 412 is penetrated by the circumferential surface of the reciprocating wire sleeve 43. When the rotating shaft 45 performs reciprocating linear motion, the force-bearing rod 46 also moves accordingly. The force-bearing block 49 is slidably connected to the inner wall of the chute 411. The side cross-section of the force-bearing block 49 is set into a T shape. There are two force-bearing rods 46. The telescopic rod 412 is fixedly connected to the inner wall of the housing 3. The force-bearing block 49 is forced to perform reciprocating linear motion on the inner wall of the chute 411.

[0027] In this embodiment, when the staff needs to dry the LCD screen after dispensing glue, the LCD screen placed on the top of the container is placed on the top of the filter plate 2, so that the LCD screen to be dried is located directly under the reciprocating screw 42. Since the LCD screen cannot be dried at too high a temperature during the drying process to prevent damage to the LCD screen, if the LCD screen is not directly under the reciprocating screw 42 during the drying process, the hot air will directly contact the LCD screen when passing through the filter port of the filter plate 2 and upward during drying, thereby damaging the LCD screen. The staff turns on the external power supply to start the motor 41, thereby forcing the reciprocating screw 42 to rotate clockwise. When the reciprocating screw 42 rotates clockwise, it drives the reciprocating wire sleeve 43 to do reciprocating linear motion. When the reciprocating wire sleeve 43 does reciprocating linear motion, The fixed plate 44 fixed on the circumferential surface of the reciprocating wire sleeve 43 also moves accordingly, prompting the rotating shaft 45 to make reciprocating linear motion. When the rotating shaft 45 makes reciprocating linear motion, it drives the force-bearing rod 46 to make reciprocating linear motion, thereby forcing the force-bearing rod 46 to make an arc motion through the rotating rod 47, so that the connecting plate 48 is forced to drive the force block 49 to make reciprocating linear motion on the inner wall of the slide groove 411. When the force block 49 makes reciprocating linear motion, it forces the push plate 410 fixed on the side of the force block 49 to make reciprocating linear motion, thereby clamping and positioning the LCD screen placed on the top of the filter plate 2 by the staff, so that the LCD screen is away from the filter port of the filter plate 2, avoiding the LCD screen from being damaged by high temperature during the drying process, saving costs and improving the work efficiency of the staff.

[0028] Example 2

[0029] like Figures 1 to 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the inner wall of the housing 3 is provided with an auxiliary device 5, which includes a sprocket 51. The sprocket 51 is fixedly connected to the circumferential surface of the reciprocating screw 42. The circumferential surface of the sprocket 51 is transmission-linked with a chain 52. The inner wall of the housing 3 is rotatably connected to a circular shaft 53. When the reciprocating screw 42 rotates clockwise, the sprocket 51 is driven to rotate clockwise. The circumferential surface of the circular shaft 53 is fixedly connected to a force-bearing wheel 54. The circumferential surface of the circular shaft 53 is fixedly connected to a gear 55. A rectangular groove 56 is formed at the top of the base 1. A rack 57 is slidably connected to the inner wall of the rectangular groove 56. A scraper 58 is fixedly connected to the top of the rack 57. When the gear 55 rotates clockwise, the rack 57 is forced to undergo reciprocating linear motion. Gear 55 and rack 57 mesh with each other, and chain 52 is connected to the circumferential surface of force-bearing wheel 54. Force-bearing wheel 54 rotates clockwise due to the tension of chain 52. Two push plates 410 are provided, symmetrically arranged along the vertical center axis of the top of filter plate 2. The push plates 410 have a T-shaped side cross-section. They perform reciprocating linear motion to clamp and position the LCD screen. The side cross-section of filter plate 2 is concave, and the side cross-section of scraper 58 is L-shaped. When scraper 58 performs reciprocating linear motion, it can scrape dust from the inner wall of filter plate 2.

[0030] In this embodiment, in the positioning device 4, when the LCD screen is positioned and safely dried, the hot air moves upward through the filter port of the filter plate 2 to dry the LCD screen. In order to prevent the hot air from carrying dust, the filter plate 2 can filter and block the dust in the hot air first. However, in order to avoid clogging of the filter plate 2, when the reciprocating screw rod 42 rotates clockwise, the sprocket 51 is driven to rotate clockwise, so that the sprocket 51 is forced to pull the force wheel 54 clockwise through the chain 52. When the force wheel 54 rotates clockwise, , the circular shaft 53 is forced to rotate clockwise, thereby driving the gear 55 fixed on the circumferential surface of the circular shaft 53 to rotate clockwise. When the gear 55 rotates clockwise, the rack 57 meshing with the gear 55 is forced to make a reciprocating linear motion on the inner wall of the rectangular groove 56, so that the scraper 58 fixed on the top of the rack 57 is close to the inner wall of the filter plate 2 and makes a reciprocating linear motion, thereby scraping the dust in the filter plate 2, avoiding the blockage of the filter plate 2, playing an auxiliary role in the drying work, and improving the work efficiency of the staff.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
