TECHNICAL FIELD

[0001] The utility model relates to display screen burr removal technical field, specifically, especially, a kind of display screen injection-molded shell burr removal device. BACKGROUND

[0002] Display screen shell is usually manufactured using injection molding process, which can quickly and mass-produce shells that meet design requirements. However, during the injection molding process, molten plastic injected under high pressure into the mold can cause additional plastic overflow at the parting surface of the mold, the sliding fit of the slider, the gap of the insert, and the edge position of the top rod aperture, forming so-called flash or burr.

[0003] These burrs not only affect the appearance, but also can cause interference or safety hazards during assembly. Therefore, removing burrs is an important step in the manufacturing process of display screen shells. Traditional burr removal methods mainly rely on manual operation, using small grinders or files and other tools to polish the burrs. Although this method is flexible, it is less efficient and heavily dependent on the operator's skills and experience. In addition, during the manual polishing process, the operator needs to continuously apply appropriate pressure to control the polishing effect, especially when dealing with burrs of different thicknesses, which requires constant adjustment of force, a challenge to the operator's physical strength and attention. Long hours of work can lead to fatigue accumulation, affecting the quality and consistency of polishing.

[0004] Therefore, in view of the above problems, a display screen injection-molded shell burr removal device is proposed to improve the comfort of use. SUMMARY

[0020] The following description is only a preferred embodiment of the present application, and does not limit the protection scope of the present application.

[0021] Example: A burr removal device for injection-molded display shells, such as... Figures 1-4 As shown, the device includes a housing 1, a motor 2, a grinding wheel 3, a guide sleeve 4, a moving rod 5, a pulley 6, and a fixing bolt 7. The housing 1 serves as the main frame of the device, and grooves 11 are spaced apart on both the left and right sides of the housing 1. The grooves 11 increase the comfort of holding the housing 1 and increase the friction between the operator and the housing 1 to improve the stability of the grip. The motor 2 is installed inside the housing 1, and the output shaft of the motor 2 passes through the front end of the housing 1. The grinding wheel 3 is connected to the output shaft of the motor 2. The rotating grinding wheel 3 can... The device is capable of removing burrs from the injection-molded housing of the display screen. Guide sleeves 4 are provided on both the left and right sides of the housing 1. Moving rods 5 are slidably installed through both guide sleeves 4. Pulleys 6 are rotatably installed on the end of the moving rods 5 facing the grinding wheel 3. The pulleys 6 are used to assist the movement during operation and to support the workpiece, thereby reducing the operating burden of the operator and improving the overall user comfort. Fixing bolts 7 are threaded through the side of the guide sleeves 4 that are far apart from each other. The fixing bolts 7 abut against the moving rods 5 on the same side. The position of the moving rods 5 can be fixed by tightening the fixing bolts 7.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a mounting sleeve 8, a buckle 9, and a protective shell 10. Mounting sleeves 8 are provided on opposite sides of the two guide sleeves 4. Buckles 9 are snapped onto the two mounting sleeves 8. A protective shell 10 is provided between the two buckles 9. The snapping cooperation between the mounting sleeves 8 and the buckles 9 makes it easier to install and remove the protective shell 10. The end of the protective shell 10 extends to the front end of the grinding wheel 3. The protective shell 10 is made of transparent material, so that the protective shell 10 can block the flying chips generated during the grinding process without obstructing the operator's view.

[0023] like Figure 1 and Figure 3 As shown, it also includes a strap 12. The outer shell 1 is provided with a strap 12, and the end of the strap 12 is inserted through one end of the outer shell 1 to assist the staff in holding and operating it.

[0024] like Figure 1 and Figure 3 As shown, the strap 12 is provided with two Velcro straps, one of which is located at the end of the strap 12 and the other is located on the side away from the end of the strap 12, so that the two can stick together to fix the strap 12 after the position is adjusted, thereby tightening the gap between the strap 12 and the hand and achieving the effect of stabilizing the position.

[0025] like Figure 4As shown, the protective shell 10 is provided with a rubber strip 13 on both sides, which can block the flying debris to a certain extent.

[0026] When the device is needed, the staff will put his hand through the bandage 12 and hold the shell 1, then pull the end of the bandage 12 to make the bandage 12 close to the hand, and then bend the end of the bandage 12 forward and fix the position of the bandage 12 with the magic tape on it. After the staff's hand is fixed, the grinding wheel 3 can be started to grind the burrs on the workpiece. In this process, the transparent material of the protective shell 10 will not interfere with the operation process, and the arc shape of the protective shell 10 and the rubber strip 13 on it can block the burrs generated during the operation to avoid affecting the operation of the staff. Then the staff pulls the moving rod 5 on both sides to move on the corresponding guide sleeve 4 to adjust the position of the pulley 6 on the workpiece. After the pulley 6 is adjusted to the appropriate supporting position, the fixed bolt 7 can be twisted to fix the position between the moving rod 5 and the guide sleeve 4. Then the pulley 6 can be removed to remove the burrs on the workpiece. With the help of the pulley 6, the stress point of the staff can be supported to a certain extent, thereby reducing the operation burden of the staff and improving the operation and use of the staff. After use, the protective shell 10 can be disassembled, the end of the buckle 9 is pinched and pushed to slide into the corresponding mounting sleeve 8, and then the protective shell 10 is not limited by the buckle 9 and the mounting sleeve 8, and can be directly taken out, and then the corresponding cleaning work can be carried out.

[0027] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
