Description

Technical Field

[0001] This utility model relates to the field of backlight module processing technology, specifically to a dispensing device for backlight module processing. Background Technology

[0002] Dispensing equipment for backlight module processing plays a crucial role in electronic device manufacturing, ensuring the precise fixation and sealing of various components within the backlight module. This dispensing equipment is specifically designed for the backlight module manufacturing process. It achieves component fixation and sealing by uniformly and precisely applying a specific adhesive to designated locations on the backlight module, thereby ensuring the quality and performance of the backlight module.

[0003] When using existing dispensing equipment, most of them choose to fix the backlight module with a fixture that matches the size of the backlight module. When dispensing backlight modules of different sizes, the staff needs to change the fixture, which is not only cumbersome and affects the dispensing efficiency, but also requires several fixtures for each machine, which increases the cost of the equipment.

[0004] Meanwhile, some existing dispensing devices do not clean the surface of the backlight module during use, which makes the surface prone to dust and foreign matter. Dust and foreign matter can affect the dispensing effect of the device, resulting in uneven glue application and poor sealing, thus reducing the applicability of the device. Utility Model Content

[0005] The purpose of this invention is to provide a dispensing device for backlight module processing to solve the problems mentioned in the background art.

[0007] A mounting bracket fixed to the output shaft of a servo motor; a dispensing mechanism is installed on one side of the worktable; a fixing bracket is fixedly connected to the surface of the mounting bracket; an adjustment mechanism is installed in the inner cavity of the fixing bracket; and a compression spring is installed on one side of the adjustment mechanism.

[0008] A positioning frame is fixed to the other side of the compression spring and the surface of the fixed frame. A connecting frame is fixedly connected to one side of the worktable. An air duct is fixedly connected to the inner cavity of the connecting frame. A cleaning mechanism is installed on one side of the air duct. A filter plate is installed on the surface of the air duct.

[0009] Preferably, the adjustment mechanism includes a threaded rod threaded to the inner cavity of the fixing frame and a sleeve threaded to its surface, wherein a fixing plate fixedly connected to one end of a compression spring is fixedly connected to the top of the sleeve.

[0010] Preferably, the cleaning mechanism includes an installation pipe connected to one side of the air duct and a nozzle connected to its surface, and a fan is installed inside the air duct.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention allows for significant adjustment of the distance between the two positioning frames through the coordination of the adjustment mechanism. This not only makes the dispensing process more convenient and effectively improves efficiency but also reduces the cost of the device. Furthermore, the compression spring facilitates easy assembly and disassembly of the backlight module.

[0021] 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.

[0022] Please see Figure 1-4As shown, a dispensing device for backlight module processing includes a worktable 1. A servo motor 2 is bolted to the inner cavity of the worktable 1. The output shaft of the servo motor 2 is fixedly connected to a mounting bracket 3. The bottom of the mounting bracket 3 is slidably connected to the top of the worktable 1, which makes the mounting bracket 3 more stable when rotating. A dispensing mechanism 4 is installed on one side of the worktable 1, which facilitates the dispensing of adhesive to the backlight module. Fixing brackets 5 are fixedly connected to the surface of the mounting bracket 3. There are several fixing brackets 5. An adjustment mechanism is installed in the inner cavity of the fixing bracket 5. 6. A compression spring 7 is installed on one side of the adjustment mechanism 6, and a positioning bracket 8 is fixedly connected to the other side of the compression spring 7 and the surface of the fixing frame 5. Under this action, when it is necessary to fix the backlight module, the two positioning brackets 8 are pressed against each other by the compression spring 7, thereby achieving the effect of fixing the backlight module. This not only makes it more convenient for the staff to handle the backlight module, but also improves the efficiency of the device. With the cooperation of the adjustment mechanism 6, the position of the compression spring 7 can be adjusted, thereby significantly changing the position of the two positioning brackets 8. The distance between the brackets 8 makes it easier to fix backlight modules of different sizes, effectively improving the applicability of the device. A connecting bracket 9 is fixedly connected to one side of the workbench 1, and an air duct 10 is fixedly connected to the inner cavity of the connecting bracket 9. A cleaning mechanism 11 is installed on one side of the air duct 10. With the cooperation of the cleaning mechanism 11 and the air duct 10, the backlight module can be cleaned, thereby reducing dust and foreign objects on its surface, effectively improving the applicability of the device. A filter plate 12 is installed on the surface of the air duct 10. It can filter dust in the air, so that the dust cleaned by the cleaning mechanism 11 from the surface of the backlight module can enter the interior of the air duct 10 and be filtered and collected by the filter plate 12. This not only improves the cleanliness of the air, but also reduces the spread of dust. The top two sides of the air duct 10 are rotatably connected to the positioning plate 13. The positioning plate 13 can block the filter plate 12, so that the filter plate 12 will not easily shift its position when the operator does not need to replace it, effectively improving the stability of the filter plate 12 during use.

[0023] The adjustment mechanism 6 includes a threaded rod 61 threadedly connected to the inner cavity of the fixed frame 5. A sleeve 62 is threadedly connected to the surface of the threaded rod 61. A fixed plate 63 is fixedly connected to the top of the sleeve 62. One side of the fixed plate 63 is fixedly connected to one end of the compression spring 7. Under this action, the sleeve 62 can be moved by rotating the threaded rod 61, thereby adjusting the position of the compression spring 7 and one side positioning frame 8 through the fixed plate 63. This allows for a significant adjustment of the position between the two positioning frames 8, effectively improving the applicability of the device. One end of the threaded rod 61 is fixedly connected to a bearing seat 17, and the other side of the bearing seat 17 is fixedly connected to the inner wall of the fixed frame 5. Under this action, one end of the threaded rod 61 is supported by the bearing seat 17, making the threaded rod 61 more stable when rotating and preventing unstable rotation from affecting the threaded connection with the sleeve 62. Guide frames 14 are fixedly connected to both sides of the surface of the fixed plate 63. Guide grooves 15 are opened on both sides of the fixed plate 63. The guide frames 14 and guide grooves 15 are used in conjunction. Under this action, the fixed plate 63 can be guided when it moves by the cooperation of the guide frames 14 and guide grooves 15, so that the fixed plate 63 can be more stable when it moves. This avoids the fixed plate 63 being unstable when it moves, which would affect the movement of the positioning frame 8 on one side. A positioning rod 16 is fixedly connected to one side of the positioning frame 8. The positioning rod 16 is located inside the compression spring 7. The other end of the positioning rod 16 passes through to the other side of the fixed plate 63 and is slidably connected to the inner wall of the through point. Under this action, the compression spring 7 can be guided and limited when the positioning frame 8 moves by the cooperation of the positioning rod 16, so that the compression spring 7 will have a large positional displacement during compression or rebound, which would affect the movement effect of the positioning frame 8.

[0024] The cleaning mechanism 11 includes an installation pipe 111 connected to one side of the air duct 10. The surface of the installation pipe 111 is connected to a nozzle 112. There are several nozzles 112, which are designed with an inclined structure. A fan 113 is installed in the inner cavity of the air duct 10. Under the action of the fan 113, the air can be accelerated, so that the air can be discharged from the nozzle 112 through the installation pipe 111, thereby cleaning the surface of the backlight module. This is not only more convenient, but also effectively improves the cleanliness of the backlight module and reduces the situation where there are too many foreign objects on the surface of the backlight module, which affects the dispensing effect.

[0025] It is worth noting that the technical features such as the worktable 1 and the dispensing mechanism 4 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0026] Working principle: First, rotate the threaded rod 61. Under the action of the thread on the surface of the threaded rod 61, the sleeve 62 drives the fixing plate 63 to move. When the fixing plate 63 moves, it can drive the compression spring 7 to adjust the position of the positioning frame 8 on one side, thereby adjusting the distance between the two positioning frames 8 to a distance that matches the size of the backlight module. This allows the device to be adjusted according to the size of the backlight module, effectively improving the applicability of the device. Then, the operator places the backlight module between the two positioning frames 8, and the compression spring 7 can fix the backlight module. Then... The servo motor 2 and mounting bracket 3 are turned on, causing the dispensing mechanism 4 and its internal parts to rotate 90 degrees. Then, the fan 113 is turned on, allowing air to flow from the inside of the air duct 10 into the mounting tube 111 and then out of the fan 113. This cleans the surface of the backlight module, and the filter plate 12 also filters out dust, which not only improves the cleanliness of the backlight module but also effectively enhances the applicability of the device. Then, the fixing bracket 5 is rotated again to make the dispensing mechanism 4 dispense glue onto the backlight module. With the number of fixing brackets 5, continuous processing can be performed, which is quite convenient.
