Description

Technical Field

[0001] This utility model relates to the field of LED display screen spraying, and specifically to a surface coating device for LED display screen modules. Background Technology

[0002] A monitor is a computer's I / O device, or output device. It is a display tool that shows electronic documents onto a screen via a specific transmission device. It can be categorized into cathode ray tube monitors (CRT), plasma display panels (PDP), and liquid crystal displays (LCD).

[0003] Chinese Patent No. CN221413686U discloses a coating device for a display panel surface. This device uses a motor-controlled transmission assembly in conjunction with a cylinder to move a spray nozzle, automatically applying a coating material to the display panel that needs repair. This ensures the coating material is evenly applied to the display panel surface. However, this coating device has the following problems: during the LED display screen spraying process, the display panel needs to be manually moved under the spray nozzle, which is time-consuming and labor-intensive, hindering the saving of manpower and resources, and resulting in poor practicality. Utility Model Content

The tilt angle of the frame can be adjusted according to different coating requirements, making the coating process more precise and improving the uniformity and quality of the coating. Four sets of corresponding first limiting mechanisms installed at both ends of the first stepped groove can accurately position and limit the LED display module placed in the groove, preventing movement of the module during coating and ensuring the accuracy of the coating position. By setting four sets of spraying components, multi-directional and multi-angle spraying can be achieved, ensuring that the surface of the LED display module is uniformly covered by the coating material. The coordinated work of multiple spraying components not only improves spraying efficiency but also allows for adjustment of the spraying parameters of each component to meet different coating requirements. The guide plate provides guidance for the coated and dried LED display modules, facilitating collection and organization by operators. The angled design allows the modules to slide naturally along the guide plate, reducing manual handling and improving work efficiency. Attached Figure Description

[0033] The lifting mechanism includes a first hydraulic rod 11 and a first hydraulic cylinder 12. The first hydraulic rod 11 is movably installed between the frame 3 and the first hydraulic cylinder 12, and the end of the first hydraulic cylinder 12 away from the first hydraulic rod 11 is movably installed on the support base plate 1.

[0034] The spraying mechanism includes four spraying components, and each adjacent spraying component is connected to the other via a first water pipe 13.

[0035] Guide plate 14, which is mounted obliquely on the support base plate 1 by means of support legs.

[0036] The first limiting component includes a first cylinder 17, a first telescopic rod 18, and a first stop 19. The bottom of the frame 3 is provided with a first bracket 20 for mounting the first cylinder 17. The first telescopic rod 18 is installed between the first cylinder 17 and the first stop 19. The first stop 19 has a limiting part 21, and one end of the first stop 19 can penetrate to the surface of the first stepped groove 4. The first stop 19 is adjusted in height on the first stepped groove 4 via the first telescopic rod 18 of the first cylinder 17. A through groove 22 is provided at the end of the support rod 6 away from the first stop 19, allowing the sprayed liquid on the second stepped groove 5 to drain easily through the through groove 22.

[0037] The first limiting mechanism includes a second hydraulic cylinder 23, a second hydraulic rod 24, and a limiting plate 25. One end of the second hydraulic rod 24 is movably connected to the second hydraulic cylinder 23, and the other end of the second hydraulic rod 24 is connected to the limiting plate 25. Several rolling wheels 26 are movably installed on the side of the limiting plate 25 away from the hydraulic cylinder.

The second cylinder 28 is mounted on the second support frame 8, and the second telescopic rod 29 is mounted between the second cylinder 28 and the second stop 30.

By setting four sets of second water pipes 32, the surface of the LED display module can be sprayed simultaneously.

[0040] The working principle of this utility model embodiment is as follows:

[0041] When using the LED display module surface coating device, the LED display module to be coated is first placed in the first stepped groove 4 of the frame 3. At this time, the first limiting mechanism is activated, and the second hydraulic cylinder 23 drives the second hydraulic rod 24, which moves the limiting plate 25. The rolling wheel 26 on the limiting plate 25 contacts the module and limits its position. At the same time, the module can be easily adjusted in position under the guidance of the rolling wheel 26 to ensure accurate placement.

[0042] One end of the frame 3 is mounted on the fixed seat 15 of the first support frame 2 via a pivot 16, allowing for flexible rotation. If the angle of the frame 3 needs to be adjusted, the first hydraulic cylinder 12 in the lifting mechanism is activated, pushing the first hydraulic rod 11 to move the frame 3 up and down around the pivot 16 to a suitable angle to meet different coating process requirements and ensure the accuracy and uniformity of the coating.

[0043] After preparation, the spraying mechanism begins operation. The coating material enters the second water pipe 32 of each spraying component via the first water pipe 13. Several spray nozzles 33 installed on the second water pipe 32 simultaneously spray the LED display module surface from multiple directions and angles, ensuring uniform coverage of the coating material. Excess coating liquid is collected through the channel 22 on the support rod 6 and the second stepped channel 5, and discharged through the discharge nozzle 34 on the side of the frame 3 near the guide plate 14. The switch 35 on the discharge nozzle 34 controls the timing of the discharge.

[0044] After spraying is completed, the frame 3 rotates to a horizontal position, transferring the module to the drying mechanism. The conveyor motor 9 starts, driving the conveyor shaft 10 to rotate, conveying the module to the area below the hot air blower 7. The hot air blower 7 generates stable and powerful hot air to quickly dry the module. During the conveying process, the second cylinder 28 in the second limiting assembly drives the second telescopic rod 29, causing the second stop 30 to extend and intercept the module, preventing it from sliding out of the first stepped groove 4 due to gravity, ensuring the stability of the module during the drying process and guaranteeing the consistency of the drying effect.

[0045] After drying, the module continues to be conveyed to the guide plate 14. The obliquely installed guide plate 14 guides the module to slide down naturally, making it convenient for operators to collect and organize, thus completing the entire coating operation process. Throughout the process, the first cylinder 17 in the first limiting assembly can drive the first telescopic rod 18, which in turn drives the first stop 19 to rise and fall, further limiting the module and ensuring the smooth operation of each stage.

[0046] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
