Description

Technical Field

[0001] This utility model relates to the field of displays, specifically to a smooth processing structure for a plastic shell bezel of a display. Background Technology

[0002] In the current monitor assembly process, in order to ensure the smoothness of the monitor bezel plastic shell, after the injection molding of the monitor bezel plastic shell is completed, a special plastic polishing component is usually used to polish the injection-molded shell. This ensures that the shell has a good smooth appearance when the monitor is assembled, thereby improving the appearance quality of the product.

[0003] Existing monitor plastic bezels are typically clamped and fixed by a fixing stage assembly, and then polished by a finishing assembly. For example, a finishing processing device for monitor plastic bezel after injection molding and demolding, as disclosed in application number 2021218941908, uses a two-way cylinder to fix the monitor plastic bezel, and then polishes it with grinding heads on both sides of the monitor plastic bezel.

[0004] While this polishing method can guarantee a smooth finish, it generates a lot of dust pollution during the process. Even with a dust extraction system like the one mentioned in the document above, it is difficult to completely remove the dust. Furthermore, using sandpaper requires multiple rounds of fine polishing to achieve the desired smoothness. A common polishing procedure is to start with #1000 sandpaper and gradually increase it to 3000 to achieve a smooth finish. During the polishing process, liquid abrasive should be applied evenly to the surface of the plastic casing and gently wiped, paying particular attention to scratches. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the smoothing components in the existing plastic shell smoothing processing structure of display bezels are difficult to complete a one-time smoothing process, and multiple repeated grinding and polishing are required during the smoothing process.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a smooth processing structure for a plastic shell of a display bezel, including a fixing table assembly for fixing the plastic bezel of the display and a smoothing assembly for polishing the side wall of the plastic bezel of the display. The smoothing assembly includes a wet sandblasting machine, a fixing table for placing the water outlet pipe of the wet sandblasting machine, and an L-shaped baffle located on one side of the contact surface between the fixing table and the fixing table assembly. The lateral side of the L-shaped baffle is connected to the fixing table by a hinge. The water outlet of the wet sandblasting machine is provided with a nozzle that passes through the vertical end of the L-shaped baffle, and the water outlet end of the nozzle is provided with a universal bamboo joint pipe.

[0007] The L-shaped baffle is provided with an L-shaped baffle angle adjustment rod and an angle drive motor connected by a pin structure on the left and right rear sides of the horizontal end.

[0008] As an improvement, the fixed platform assembly includes a worktable for placing the plastic bezel of the display, several double-headed cylinders located above the worktable, several hydraulic lifting rods located below the worktable, and a pulley table located below the base of the hydraulic lifting rods.

[0009] As an improvement, the output shaft of the double-headed cylinder is provided with several detachable extension rods, and each detachable extension rod and the output shaft of the double-headed cylinder are connected by threads.

[0010] As an improvement, the top of the outermost detachable extension rod is fitted with an anti-slip cap.

[0011] As an improvement, a convex slider is provided on one side of the inner wall of the workbench, which passes through the fixed table.

[0012] As an improvement, the wet sandblasting machine is equipped with a controller on one side to control the various circuits and pneumatic components.

[0013] The advantages of this invention compared to existing technologies are as follows: This device uses an abrasive-water mixture sprayed from a wet sandblasting machine to flush the outer wall of the monitor's plastic frame. The water pressure is controlled by adjusting the output pressure of the wet sandblasting machine, thus ensuring that the monitor's plastic frame is not damaged. During flushing, to facilitate rinsing the top surface of the monitor's plastic frame, an L-shaped baffle is installed at the nozzle and connected to a fixed table via a hinge, allowing the nozzle to rotate 90 degrees. This ensures that the top surface can be cleaned without changing the clamping mechanism. The rotation of the L-shaped baffle is controlled by an angle adjustment rod and an angle-driven motor, ensuring the safety of nearby personnel during operation. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] As per the instruction manual Figure 1 , 2 As shown in Figures 3 and 4, the existing display bezel plastic shell smoothing processing structure includes a fixing platform assembly 2 for fixing the display plastic bezel 1 and a smoothing assembly 3 for polishing the side wall of the display plastic bezel 1.

[0021] To ensure that the outer wall of the monitor's plastic bezel 1 can be cleaned without dust in one go, the surface cleaning assembly 3 includes a wet blasting machine 31, a fixed table 32 for placing the water outlet pipe of the wet blasting machine 1, and an L-shaped baffle 33 located on the side of the contact surface between the fixed table 32 and the fixed platform assembly 2. The lateral side of the L-shaped baffle 33 is connected to the fixed table 32 by a hinge. To facilitate the fixing of the water outlet pipe of the wet blasting machine 1, the outlet of the wet blasting machine 1 is provided with a through-hole of the L-shaped baffle 3. The nozzle 311 at the vertical end is connected to the inner wall of the L-shaped baffle 33 by bolts. The water inlet of the nozzle 311 is connected to the water outlet of the water outlet pipe of the wet sandblasting machine 1 by cable ties. In order to avoid the nozzle 311 hitting the plastic frame 1 of the display, a universal bamboo joint pipe 312 is provided at the water outlet of the nozzle 311, which is the pipe commonly used for the outlet of CNC machine tool cutting fluid. In order to save space, the wet sandblasting machine 1 is generally located below the fixed table 32.

[0022] To facilitate the control of the L-shaped baffle 33's rotation, the left and right rear sides of the horizontal end of the L-shaped baffle 33 are provided with an L-shaped baffle 33 angle adjustment rod 331 and an angle push motor 332 connected by a pin structure. In order to ensure that the linear push of the angle push motor 332 does not affect the movement of the angle adjustment rod 331, a groove adapted to the angle push motor 332 can be carved out on the fixed table 32.

[0023] The fixed platform assembly 2 includes a worktable 21 for placing the display plastic bezel 1, several double-headed cylinders 22 located above the worktable 21, several hydraulic lifting rods 23 located below the worktable 21, and a pulley table 24 located below the base of the hydraulic lifting rods 23. The pulley table 24 and the worktable 21 are connected to the base and the top of the output shaft of the hydraulic lifting rods 23 by bolts. The double-headed cylinders 22 are also connected to the worktable 21 by bolts. The hydraulic lifting rods 23 are used to ensure that when processing the tall display plastic bezel 1, it can be rinsed layer by layer, just like the layer-by-layer cutting of a CNC machine tool, to ensure the integrity of rinsing. Similarly, to ensure that there is no shaking during rinsing, a convex slider 211 passing through the fixed table 32 is provided on one side of the inner wall of the worktable 21. The convex slider 211 is slidably connected to the corresponding slide groove to ensure stability during rinsing. In order to facilitate the control of the movement speed of the display plastic bezel 1, the pulley table 24 is usually electrically controlled.

[0024] To facilitate control of the position of the plastic bezel 1 of monitors of different sizes, the output shaft of the double-headed cylinder 22 is provided with several detachable extension rods 221, and each detachable extension rod 221 and the output shaft of the double-headed cylinder 22 are connected by threads. That is, the output ends of both ends of the double-headed cylinder 22 are threaded ends, while the bottom end of the detachable extension rod 221 is a screw hole and the top surface is threaded. The position of the flushing end of the plastic bezel 1 of the monitor can be controlled by adjusting the number of detachable extension rods 221 on both sides of the double-headed cylinder 22, so as to avoid the situation where the water flow cannot reach the plastic bezel 1 of the monitor.

[0025] To avoid friction between the detachable extension rod 221 and the inner wall of the display plastic frame 1, the top of the outermost detachable extension rod 221 is fitted with an anti-slip cap.

[0026] To facilitate the control of various circuits and pneumatic components, a dedicated controller 4 is installed on one side of the wet sandblasting machine 31.

[0027] In a specific implementation of this invention, the display plastic frame 1 is placed on the workbench 21. Then, the position of the end of the display plastic frame 1 to be rinsed is adjusted. By adjusting the number of detachable extension rods 221, the position of the end of the display plastic frame 1 to be rinsed is made to be within the effective rinsing range of the water flow from the nozzle 311. Then, the height of the display plastic frame 1 is adjusted by the hydraulic lifting rod 23 so that the nozzle 311 can completely rinse the entire surface. If the display plastic frame 1 is too wide, it needs to be rinsed layer by layer. During rinsing, the convex slider 211 needs to be slid into the groove of the fixed table 32 for limiting. After the side rinsing is completed, the angle push motor 332 is activated, so that the L-shaped baffle 33 flips along the hinge, so that the nozzle 311 is perpendicular to the top surface of the display plastic frame 1, and the top surface of the display plastic frame 1 is rinsed.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
