[0002] The waterproof adhesive coating equipment for display modules adopts a high-precision metering pump and dynamic / static mixing technology, supports an adjustable adhesive ratio from 1:1 to 10:1, and achieves an adhesive dispensing accuracy of ±0.02 grams. It is suitable for two-component adhesives such as silicone, epoxy, and polyurethane. The equipment is equipped with a 12-inch touch screen and a teaching programming system, which can store 99 sets of process parameters. It supports coating of complex trajectories such as straight lines, curves, and circles, and is compatible with an 800mm×800mm working stroke, meeting the IP65 waterproof requirements of outdoor LED modules.

[0003] In the actual production environment of display modules, there is vibration and dust interference in the workshop, and the modules are slightly offset. Traditional equipment relies on bolts and clamps for positioning, which can easily lead to the offset of the coating starting point and trajectory. In addition, the dimensional tolerance of different batches of modules fluctuates, which further aggravates the deviation of the adhesive coating position, resulting in problems such as missed coating and overflow of adhesive, which seriously affect the waterproof performance and product yield. Therefore, this utility model proposes a waterproof adhesive coating equipment for display modules to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a waterproof adhesive coating device for display modules, which solves the problems in the prior art caused by workshop vibration, dust, module placement misalignment, poor positioning of traditional equipment, batch size fluctuations, resulting in adhesive coating deviation, missed coating and overflow, and a significant drop in yield.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a waterproof adhesive coating device for display module, including a base, slide rails and a fixing plate. Slide rails are symmetrically installed on both sides of the base. A connecting frame is slidably connected inside the slide rails. A fixing plate is fixedly connected to the top of the connecting frame. A movable frame is fixedly installed on the top of the base. A sliding arm is slidably connected inside the movable frame. A coating mechanism is provided at the bottom of the sliding arm. A driving mechanism is provided inside one of the slide rails and the movable frame. A positioning mechanism is provided at the bottom of the fixing plate.

[0006] A further improvement is made in that: the positioning mechanism includes a limiting frame, a connecting block, a clamping plate, a rotating rod, a linkage rod, and a driving cylinder. The limiting frame is fixedly connected to the bottom of the fixed plate. The connecting blocks are symmetrically and slidably connected to both sides of the limiting frame. The clamping plate is fixedly connected to the top of the connecting blocks. The rotating rod is rotatably connected to the bottom of the limiting frame. The two ends of the rotating rod are respectively hinged to the bottom of the connecting blocks through two linkage rods. The driving cylinder is fixedly installed at the bottom of the limiting frame. The output end of the driving cylinder is fixedly connected to the bottom of the connecting block.

[0007] A further improvement is that the height of the clamping plate is greater than the height of the top of the fixing plate, and a rubber pad is glued to one side of the clamping plate.

[0008] A further improvement is that the coating mechanism includes a lifting cylinder, a movable frame, a nozzle, and a glue pump. The movable frame is slidably intercepted at the bottom end of the sliding arm. A nozzle is fixedly connected to one side of the movable frame. A glue pump is also installed on the movable frame. The output end of the glue pump is connected to the top of the nozzle through a hose.

[0009] A further improvement is that the input end of the glue pump is connected to the inside of the glue bucket through a hose, and a lifting cylinder is installed on one side of the sliding arm. The output end of the lifting cylinder is fixedly connected to the top of the movable frame.

[0010] A further improvement is that the driving mechanism includes a motor and a lead screw. The movable frame is rotatably connected to the inside of one of the slide rails by the lead screw. The movable frame and one of the slide rails are both fixedly mounted with a motor on one side. The output end of the motor is fixedly connected to one end of the lead screw. One end of each of the two lead screws passes through the interior of the connecting frame and the sliding arm and is threadedly connected to them.

[0011] A further improvement is that a protective shell is fixedly installed on the outside of the motor, and multiple anti-collision strips are fixedly connected in a ring on the outside of the protective shell. The anti-collision strips are rectangular in shape.

[0012] The beneficial effects of this utility model are as follows: the display module is placed on the top of the fixed plate, the output end of the drive cylinder retracts inward, and drives the rotating rod to rotate counterclockwise. The rotating rod pulls the two clamping plates simultaneously towards both sides of the display module through the linkage rod and connecting block, thereby locking the display module in a fixed position on the top of the fixed plate. This improves the accuracy of coating the display module with waterproof adhesive, and solves the problems of workshop vibration, dust, module placement misalignment, poor positioning of traditional equipment, batch size fluctuations, resulting in adhesive coating deviation, missed coating and overflow, and a significant drop in yield in the prior art.

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a waterproof adhesive coating device for a display module, including a base 1, a slide rail 2, and a fixing plate 3. The slide rail 2 is symmetrically installed on both sides of the base 1. A connecting frame 18 is slidably connected inside the slide rail 2. The fixing plate 3 is fixedly connected to the top of the connecting frame 18. A movable frame 4 is fixedly installed on the top of the base 1. A sliding arm 11 is slidably connected inside the movable frame 4. A coating mechanism is provided at the bottom of the sliding arm 11. A driving mechanism is provided inside one of the slide rails 2 and the movable frame 4. A positioning mechanism is provided at the bottom of the fixing plate 3. The display module is placed on the top of the fixing plate 3. The positioning mechanism locks the display module in a fixed position on the top of the fixing plate 3. The driving mechanism moves the coating mechanism to the outer edge of the display module. Then, the driving mechanism drives the coating mechanism to move around the outer edge of the display module to automatically coat the waterproof adhesive on the outer edge of the display module.

[0019] The positioning mechanism includes a limiting frame 5, a connecting block 6, a clamping plate 7, a rotating rod 8, a linkage rod 9, and a driving cylinder 10. The limiting frame 5 is fixedly connected to the bottom of the fixed plate 3. The connecting blocks 6 are symmetrically slidably connected to both sides of the limiting frame 5. The clamping plate 7 is fixedly connected to the top of the connecting blocks 6. The rotating rod 8 is rotatably connected to the bottom of the limiting frame 5. The two ends of the rotating rod 8 are hinged to the bottom of the connecting blocks 6 through two linkage rods 9. The driving cylinder 10 is fixedly installed at the bottom of the limiting frame 5. The output end of the driving cylinder 10 is fixedly connected to the bottom of the connecting block 6. When the display module is placed on the top of the fixed plate 3, the output end of the driving cylinder 10 retracts inward and drives the rotating rod 8 to rotate counterclockwise. The rotating rod 8 pulls the two clamping plates 7 towards both sides of the display module simultaneously through the linkage rod 9 and the connecting block 6, thereby locking the display module in a fixed position on the top of the fixed plate 3 to position the display module and improve the accuracy of the waterproof adhesive coating on the display module.

[0020] The height of the clamping plate 7 is greater than the height of the top of the fixing plate 3. A rubber pad is glued to one side of the clamping plate 7. The rubber pad is soft and reduces the rigid contact between the clamping plate 7 and the display module, thus protecting the display module.

[0021] The coating mechanism includes a lifting cylinder 12, a movable frame 13, a nozzle 14, and a glue pump 15. The bottom end of the sliding arm 11 slides and intercepts the movable frame 13. The nozzle 14 is fixedly connected to one side of the movable frame 13. The glue pump 15 is also installed on the movable frame 13. The output end of the glue pump 15 is connected to the top of the nozzle 14 through a hose. The input end of the glue pump 15 is connected to the inside of the glue bucket through a hose. The lifting cylinder 12 is installed on one side of the sliding arm 11. The output end of the lifting cylinder 12 is fixedly connected to the top of the movable frame 13. When the valve on the hose is opened, the glue pump 15 and the hose work together to automatically deliver the glue inside the glue bucket to the inside of the nozzle 14. The lifting cylinder 12 drives the nozzle 14 to move downward through the movable frame 13. After the nozzle 14 contacts the outer edge of the display module, the nozzle 14 automatically coats the outside of the display module with waterproof glue.

[0022] The driving mechanism includes a motor 16 and a lead screw 17. The lead screw 17 is rotatably connected inside the movable frame 4 and one of the slide rails 2. The motor 16 is fixedly installed on one side of the movable frame 4 and one of the slide rails 2. The output end of the motor 16 is fixedly connected to one end of the lead screw 17. One end of the two lead screws 17 passes through the interior of the connecting frame 18 and the sliding arm 11 and is threadedly connected to them. The movable frame 4 and one of the slide rails 2 respectively restrict the movement trajectory of the sliding arm 11 and the connecting frame 18. The output ends of the two motors 16 respectively drive the two lead screws 17 to rotate in opposite directions inside the movable frame 4 and one of the slide rails 2, so as to drive the sliding arm 11 and the connecting frame 18 to move back and forth in a straight line along the movable frame 4 and the slide rail 2, that is, the connecting frame 18 drives the fixed plate 3 to move along the X direction, and the sliding arm 11 drives the nozzle 14 to move along the Y direction, so as to apply waterproof glue to the outside of the rectangular display module through the nozzle 14.

[0023] A protective shell is fixedly installed on the outside of the motor 16. Multiple anti-collision strips are fixedly connected to the outer side of the protective shell in a ring. The anti-collision strips are rectangular in shape. The protective shell and anti-collision strips can wrap around the motor 16, isolate the motor 16 from external objects, prevent the motor 16 from directly contacting external objects, and protect the motor 16.

[0024] The waterproof adhesive coating equipment for the display module places the display module on top of the fixed plate 3, drives the output end of the cylinder 10 to retract inward, and drives the rotating rod 8 to rotate counterclockwise. The rotating rod 8 pulls the two clamping plates 7 simultaneously towards the two sides of the display module through the linkage rod 9 and the connecting block 6, so as to lock the display module in a fixed position on the top of the fixed plate 3, thereby positioning the display module and improving the accuracy of waterproof adhesive coating on the display module.
