Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flash processing, in particular to a device for processing the injection molding flash of a display screen plastic frame. Background Art
[0002] Flash (also known as burrs or overflow) that occurs during the injection molding process of display frame plastics refers to the excess plastic that overflows beyond the mold parting surface during molding due to factors such as loose mold closure, excessive injection pressure, or excessive material fluidity. Addressing this flash is a crucial step in ensuring product quality and appearance.
[0003] Chinese utility model patent CN221560769U discloses a flash cleaning device for the production of plastic products. The device is equipped with a polishing structure, which can adjust the grinding roller according to the size of the plastic product and the position of the flash, so that the grinding roller and the flash are more closely fitted, thereby improving the flash processing effect. The rotation adjustment component is provided to adjust the orientation of the plastic product, thereby avoiding repeated up and down loading of the plastic product, thereby improving the processing efficiency of the plastic product. However, in actual use, the device still has shortcomings. The device can only grind the workpiece side by side. For plastic products that need to process flash on both the inside and outside sides at the same time, the grinding part of the device must perform multiple reciprocating movements to achieve all-round grinding processing, which not only increases unnecessary strokes, but also significantly reduces overall work efficiency.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] like Figure 1-Figure 5 As shown, the embodiment of the present invention provides a device for processing injection molding flash of a display screen frame, comprising a substrate 1 and an electric guide rail 2 mounted on the upper surface of the substrate 1, and a slide 4 is slidably provided on the electric guide rail 2, see Figure 5 A carrying plate 41 is rotatably provided on the slide 4, and the display screen plastic frame to be processed with burrs is placed on the carrying plate 41, and the electric guide rail 2 can drive the slide 4 and the carrying plate 41 to move as a whole.
[0020] See Figure 1 The front and rear of the upper surface of the substrate 1 are each provided with a set of grinding structures, and the flash processing of the display screen frame is completed by the grinding structure. Figure 2 The grinding structure includes a gantry arch 3 fixedly set on the base plate 1. The two ends of the bottom of the gantry arch 3 are located on the outside of the electric guide rail 2. When the slide 4 and the carrier plate 41 move, they can pass through the gantry arch 3. An electric push rod Ⅰ31 is installed vertically downward in the middle position of the top of the gantry arch 3. The movable end of the electric push rod Ⅰ31 is connected to the frame plate 32. When the electric push rod Ⅰ31 is started, the movable end is extended or contracted, which can drive the frame plate 32 to descend or ascend. A two-way screw rod 33 is rotatably provided on the upper part of the frame plate 32, and two sliding frames 35 are symmetrically slidably provided on the frame plate 32, and the two sliding frames 35 are respectively connected to the parts of the two-way screw rod 33 that rotate in different directions, see Figure 2From this perspective, a motor 34 is mounted on the left end of the frame 32. The output shaft of the motor 34 is fixedly connected to the bidirectional screw 33. When the motor 34 rotates forward, it drives the bidirectional screw 33 to rotate clockwise, causing the two slide frames 35 to move closer together. When the motor 34 rotates reversely, it drives the bidirectional screw 33 to rotate counterclockwise, causing the two slide frames 35 to move away from each other. Slides 36 are slidably mounted on each slide frame 35, and electric push rods II 38 are mounted horizontally on each slide frame 35. The movable ends of the electric push rods II 38 are fixedly connected to the corresponding slides 36. The electric push rods II 38 can be used to adjust the position of the slides 36 on the slide frames 35. An electric grinder I 37 is mounted vertically downward on the slide 36, and an electric grinder II 39 is mounted on the end of the slide frame 35. The electric grinder I 37 and the electric grinder II 39 cooperate to grind both the inside and outside of the display screen plastic frame at the same time. The position of the slide 36 on the slide frame 35 can be adjusted by the electric push rod II 38, thereby changing the distance between the electric grinder I 37 and the electric grinder II 39, so that the display screen plastic frames of different thicknesses can also be processed. Figure 1 A dust removal fan 7 is also installed on the gantry arch 3. When the display screen plastic frame is polished, the polishing residue can be blown away in time to avoid obstruction to subsequent operations.
[0021] See Figure 1 and Figure 3 The front and rear parts of the upper surface of the base plate 1 are each provided with a set of limiting structures, the limiting structures including two N-shaped frames 5 symmetrically fixedly provided on the base plate 1, and the limiting frames 51 are both slidably provided on the two N-shaped frames 5. Figure 1 The two limit frames 51 cooperate to limit the display screen frame on the carrier plate 41 so that it cannot move in the front and back directions. The limit frames 51 are provided with rollers to guide the display screen frame when the slide 4 and the carrier plate 41 move to the right. Figure 3 A screw 52 is rotatably provided on the limit frame 51, and the screw 52 rotates with the N-shaped frame 5. By rotating the two screws 52 clockwise at the same time, the two limit frames 51 can be moved away from each other along the N-shaped frame 5. By rotating the two screws 52 counterclockwise at the same time, the two limit frames 51 can be moved closer to each other along the N-shaped frame 5, thereby being able to adapt to display screen frames of different sizes and clamp and limit them.
[0022] See Figure 1 、 Figure 4 and Figure 5 A guide plate 6 is fixedly provided in the middle of the base plate 1, and a straight tooth plate 61 is provided on the guide plate 6. Figure 5A full gear 62 is provided at the rotating connection between the slide 4 and the supporting plate 41, and the full gear 62 and the spur plate 61 are adapted to each other. When the slide 4 moves to the middle of the base plate 1, the full gear 62 and the spur plate 61 engage with each other. When the slide 4 moves to the position of the gantry arch 3 at the rear of the base plate 1, the full gear 62 will rotate clockwise under the action of the spur plate 61, and make the supporting plate 41 rotate 90° clockwise relative to the slide 4, and the display screen rubber frame on the supporting plate 41 will also rotate 90°. Subsequently, the second set of grinding structures can be used to grind the corresponding side edges of the display screen rubber frame.

The description of the above embodiments is only used to help understand the method and core idea of the present application. At the same time, for those skilled in the art, based on the idea of the present application, there may be changes in the specific implementation methods and application scope.
