Description

Technical Field

[0001] This utility model relates to the field of liquid crystal module processing technology, specifically to a dispensing device with an anti-displacement structure. Background Technology

[0002] An LCD module is an integrated assembly that combines a liquid crystal display (LCD) and related driving circuits, backlight, and other components. It is commonly used for display functions in various electronic devices. Its main components include an LCD panel, a driver IC, a backlight, and connectors. The LCD panel is its core component, composed of liquid crystal molecules. An electric field is applied to adjust the alignment of these molecules, thereby controlling the switching of pixels. The driver IC receives input signals and converts them into driving signals suitable for the LCD display, controlling the brightness and color of the pixels. The backlight provides the light source, ensuring the image on the LCD panel is clearly visible in dark environments. Connectors are used to connect the LCD module to other electronic devices, such as motherboards and control circuits. The manufacturing process of an LCD module involves the production of the LCD panel, the installation and debugging of the driver IC, the assembly of the backlight, and the soldering of the connectors. Strict control of the production process is required to ensure that product quality and performance meet expectations. LCD module dispensing equipment is needed in the processing of LCD modules.

[0003] An existing patent (publication number: 202220162413.X) discloses a dispensing device for LCD module processing. It features a stirring assembly within a glue storage tank and a transmission column at the output of an electric motor. The transmission column rotates through the inner ring of a sealed bearing, preventing the glue in the storage tank from solidifying and ensuring a smooth dispensing process, thus improving efficiency and productivity. However, in developing this solution, the inventors discovered the following unresolved issues in the existing technology: The assembly process of LCD modules requires highly precise position control to ensure correct alignment of components. The aforementioned solution only uses suction cups to fix the LCD module during dispensing. While suction cups provide some adhesion, they may lose their adhesion and detach under prolonged use or heavy loads, causing the LCD module to fall or shift. This increases the risk of accidental damage and workplace safety. Module shifting may lead to glue overflow or uneven coating, affecting the product's appearance and performance stability, and even damaging components such as the LCD panel, increasing scrap rates, reducing production efficiency, and potentially causing quality and cost risks.

[0004] In response to the above situation, technological innovations will be carried out based on existing dispensing equipment. Utility Model Content

[0005] The purpose of this invention is to provide a dispensing device with an anti-displacement structure to solve the problem mentioned in the background art that using only a suction cup to fix the liquid crystal module during the dispensing process can easily cause the liquid crystal module to fall or shift, increasing the risk of accidental damage and work safety. It may also cause glue to overflow or be unevenly coated, affecting the appearance quality and performance stability of the product, and even causing damage to components such as the liquid crystal panel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dispensing device with an anti-displacement structure, comprising a dispensing table, a limiting box fixedly connected to the top of the dispensing table, a servo motor fixedly connected to the bottom of the dispensing table, the output end of the servo motor penetrating the inner surface of the dispensing table and extending into the inner cavity of the limiting box, a gear fixedly connected to the output end of the servo motor, toothed plates meshing with the front and back sides of the gear, a connecting rod fixedly connected to the top of the toothed plates, a vertical plate fixedly connected to the top of the connecting rod, a fixing plate fixedly connected to the top of the inner side of the vertical plate, a screw threadedly connected to the inner surface of the fixing plate, a limiting plate movably connected to the bottom of the screw, and a support plate fixedly connected to the top of the inner side of the vertical plate.

[0009] Preferably, a transverse sliding groove is provided on the front side of the top left side of the limiting box and the back side of the top right side of the limiting box. A transverse slider is fixedly connected to one side of the bottom of the vertical plate, and the bottom of the transverse slider is slidably connected to the inner cavity of the transverse sliding groove.

[0010] Preferably, the front and back sides of the inner wall of the limiting box are provided with limiting grooves, and the left and right sides of the outer side of the toothed plate are fixedly connected to limiting sliders, and the outer side of the limiting sliders is slidably connected to the inner cavity of the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This dispensing equipment with an anti-displacement structure, by setting a servo motor, can drive the gear to rotate. During the rotation of the gear, the meshing action of the teeth simultaneously drives the tooth plates on both sides to move inward. Through the transmission of the connecting rod, the vertical plate can be driven to move inward, limiting the left and right sides of the LCD module and preventing it from shifting during use. During the rotation of the screw, the screw moves downward by the action of the thread and drives the limiting plate to move downward. Through the cooperation between the limiting plate and the support plate, the LCD module can be limited vertically, further improving the anti-displacement effect of the LCD module, thereby improving the dispensing quality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: a dispensing device with an anti-displacement structure, including a dispensing table 1, a limiting box 2 fixedly connected to the top of the dispensing table 1, a servo motor 3 fixedly connected to the bottom of the dispensing table 1, the output end of the servo motor 3 penetrating the inner surface of the dispensing table 1 and extending into the inner cavity of the limiting box 2, a gear 13 fixedly connected to the output end of the servo motor 3, a toothed plate 14 meshing with the front and back sides of the gear 13, a connecting rod 15 fixedly connected to the top of the toothed plate 14, a vertical plate 12 fixedly connected to the top of the connecting rod 15, a fixing plate 20 fixedly connected to the top of the inner side of the vertical plate 12, a screw 21 threadedly connected to the inner surface of the fixing plate 20, a limiting plate 22 movably connected to the bottom of the screw 21, a support plate 23 fixedly connected to the top of the inner side of the vertical plate 12, and protective pads 24, which are made of low-elasticity rubber, are bonded to the bottom of the limiting plate 22 and the top of the support plate 23.

[0020] It should be noted that: by setting the servo motor 3, the gear 13 can be driven to rotate. During the rotation of the gear 13, the meshing of the teeth will drive the two side tooth plates 14 to move inward. This will drive the vertical plate 12 to move inward through the transmission of the connecting rod 15, thus limiting the left and right sides of the LCD module and preventing it from shifting during use. During the rotation of the screw 21, the screw will move downward and drive the limiting plate 22 to move downward. The cooperation between the limiting plate 22 and the support plate 23 will limit the LCD module vertically, further improving the anti-displacement effect of the LCD module and thus improving the dispensing quality. By setting the protective pad 24, the LCD module can be prevented from sliding during the limiting process, and the LCD module can be protected. The elastic force will prevent the clamping force generated during the cooperation of the limiting plate 22 and the support plate 23 from damaging it.

[0021] Specifically, the top left back side and the top right front side of the limiting box 2 are both provided with through grooves 18. The top of the connecting rod 15 passes through the inner cavity of the through groove 18 and extends to the top of the limiting box 2. The top left front side and the top right back side of the limiting box 2 are both provided with transverse sliding grooves 19. A transverse slider 11 is fixedly connected to one side of the bottom of the vertical plate 12. The bottom of the transverse slider 11 is slidably connected to the inner cavity of the transverse sliding groove 19. Limiting sliding grooves 16 are provided on the front and back sides of the inner wall of the limiting box 2. Toothed plate 14 Limiting sliders 17 are fixedly connected to both the left and right sides of the outer side. The outer side of the limiting sliders 17 is slidably connected to the inner cavity of the limiting groove 16. Slide seats 4 are fixedly connected to both the left and right sides of the top of the dispensing table 1. Sliders 5 are slidably connected to the surface of the slide seats 4. Electric push rods 6 are fixedly connected to the top of the sliders 5. Top plate 7 is fixedly connected to the output end of the electric push rod 6. Slide rail 8 is fixedly connected to the bottom of the top plate 7. Dispensing head 9 is slidably connected to the bottom of the slide rail 8. Support frames 10 are fixedly connected to both the left and right sides of the bottom of the dispensing table 1.

[0022] It should be noted that: by setting the horizontal slider 11 and the horizontal slide groove 19, the smoothness of the vertical plate 12 during left and right movement can be effectively improved; by setting the limiting slide groove 16 and the limiting slider 17, the toothed plate 14 can be supported and limited, and the stability of the toothed plate 14 during left and right movement can be effectively improved; by setting the through groove 18, the connecting rod 15 can be guided and limited; and by setting the support frame 10, the whole structure can be supported.

[0023] Working principle: For this type of dispensing equipment, the output end of the servo motor 3 first drives the gear 13 to rotate. During the rotation, the gear 13 uses the meshing action of the teeth to drive the two side tooth plates 14 to move inward. The tooth plates 14, through the transmission of the connecting rod 15, simultaneously drive the two side vertical plates 12 to move inward, limiting the left and right distance. Then, the LCD module is mounted on the top of the support plate 23. The servo motor 3 is started again to finely adjust the two side vertical plates 12 inward until the LCD module is limited to the left and right. Then, the screw 21 is rotated. During the rotation, the screw 21 moves downward using the action of the thread. The screw 21 drives the limiting plate 22 to move downward, so that the bottom of the protective pad 24 contacts the top of the LCD module. Through the cooperation between the limiting plate 22 and the support plate 23, the LCD module is limited in the upper and lower directions, further improving the anti-displacement effect of the LCD module, thereby improving the dispensing quality.
