[0002] The monitor frame is an important component of the monitor's casing, typically made of metal (such as aluminum alloy) or plastic. It not only supports and protects the internal components of the monitor but also directly affects the product's appearance quality and assembly precision.

[0003] Polishing is a crucial step in the manufacturing process of a monitor's frame. Polishing removes burrs, smooths edges, improves surface finish, and ensures the frame's dimensional accuracy and aesthetics. A good polishing result contributes to enhancing the overall quality of the monitor and the user experience.

[0004] With the rapid development of the electronics manufacturing industry, the market has increasingly higher requirements for the quality of monitor frames. Traditional manual polishing methods can no longer meet the needs of efficient production. Therefore, a polishing device for monitor frame processing has been proposed to solve the above problems.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5A grinding device for processing the display frame in this embodiment includes a worktable 1, a frame 2 fixedly installed on the top of the worktable 1, conveyor belts 3 are provided on both the left and right sides of the front side of the worktable 1, clamping mechanisms 4 are provided on both the left and right sides of the top of the worktable 1, the rear end of the conveyor belts 3 extends to the front side of the clamping mechanisms 4, a rotating mechanism 5 is provided at the center of the top of the worktable 1, and a grinding mechanism 6 is provided at the rear end of the top of the worktable 1.

[0023] In this embodiment, the grinding mechanism 6 includes a back plate 61, a disc 62, a slide rail 63, a slider 64, a cylinder 65, a connecting rod 66, a drive motor 67, a grinding roller 68, and a U-shaped block 69. The back plate 61 is positioned above the worktable 1 and behind the rotating mechanism 5. A U-shaped block 69 is fixedly installed at the center of the front of the back plate 61. The disc 62 is rotatably installed on the front of the U-shaped block 69. A slide rail 63 is fixedly installed above the front of the back plate 61. A slider 64 is slidably installed on the slide rail 63. A connecting rod 66, one end of which is hinged to the front of the slider 64, is hinged to the disc 62. A cylinder 65 is fixedly installed on the right side of the back plate 61. The output end of the cylinder 65 is fixedly connected to the slider 64. Multiple drive motors 67 are fixedly installed at the bottom of the back of the disc 62. The output end of the drive motor 67 extends through and to the front of the disc 62. A grinding roller 68 is fixedly installed at the output end of the drive motor 67.

[0024] It should be noted that the multiple grinding rollers 68 have different grinding fineness, similar to sandpaper with different grit.

[0025] Specifically, starting the drive motor 67 rotates the grinding roller 68 to perform grinding operations on the middle frame; in addition, operating the cylinder 65 drives the slider 64 to slide horizontally, and the slider 64 drives the disc 62 to rotate at a certain angle through the connecting rod 66, thereby driving different grinding rollers 68 to perform coarse grinding first and then fine grinding, improving the grinding effect of the middle frame.

[0026] In this embodiment, a mounting base 11 is provided at the top rear end of the workbench 1, a linear module 12 is provided at the top of the mounting base 11, a linear module 2 13 is provided at the output end of the linear module 12, and a back plate 61 is fixedly installed at the output end of the linear module 2 13.

[0027] Specifically, operating linear module 12 and linear module 2 13 can drive the grinding roller 68 to move.

[0028] In this embodiment, the rotating mechanism 5 includes a rotating disk 51, a drive motor 52, and L-shaped holes 53. The drive motor 52 is fixedly installed on the top of the workbench 1 and between the two conveyor belts 3. The rotating disk 51 is fixedly installed at the output end of the drive motor 52. Four sets of L-shaped holes 53 are opened on the top of the rotating disk 51. Each of the four sets of L-shaped holes 53 includes four L-shaped holes 53. The four L-shaped holes 53 are rectangularly distributed on the rotating disk 51.

[0029] Specifically, starting the drive motor 52 can rotate the rotating disk 51, and the rotating disk 51 drives the middle frame to move in position.

[0030] In this embodiment, a positioning mechanism 7 is provided at the top rear end of the workbench 1 and below the rotating disk 51. The positioning mechanism 7 includes a hydraulic push rod 71, a mounting plate 72, and an L-shaped plate 73. The hydraulic push rod 71 is fixedly installed at the top rear end of the workbench 1 and below the rotating disk 51. The output end of the hydraulic push rod 71 is fixedly installed with the mounting plate 72. The top four sides of the mounting plate 72 are all fixedly installed with L-shaped plates 73, and the L-shaped plates 73 match the L-shaped holes 53.

[0031] Specifically, the hydraulic push rod 71, carrying the L-shaped plate 73, passes through the L-shaped hole 53 and extends into the area around the middle frame placed on the rotating disk 51, which can limit the middle frame and prevent displacement during the grinding process.

[0032] In this embodiment, the clamping mechanism 4 includes a vertical plate 41, a linear module 3 42, a suction nozzle frame 43, a negative pressure suction nozzle 44, and an electric push rod 45. The vertical plate 41 is fixedly installed on both the left and right ends of the top of the workbench 1. The linear module 3 42 is fixedly installed on the top of the vertical plate 41. A push rod frame is fixedly installed on the output end of the linear module 3 42. An electric push rod 45 is fixedly installed on the push rod frame. The suction nozzle frame 43 is fixedly installed on the output end of the electric push rod 45. Negative pressure suction nozzles 44 are embedded around the top of the suction nozzle frame 43.

[0033] Specifically, operating the electric push rod 45 moves the negative pressure suction nozzle 44 up and down, operating the negative pressure suction nozzle 44 can adsorb the middle frame or release the adsorption state, and operating the linear module 3 42 can move the middle frame horizontally.

[0034] The working principle of the above embodiments is as follows:

[0035] (1) Place the middle frame to be polished on the conveyor belt 3. The conveyor belt 3 moves the middle frame to the inside of the worktable 1. Operate the electric push rod 45 to move the negative pressure suction nozzle 44 downward. Operate the negative pressure suction nozzle 44 to perform the adsorption operation of the middle frame. Then operate the electric push rod 45 and the linear module 3 42 to move the middle frame to the rotating disk 51. Operate the electric push rod 45 and the negative pressure suction nozzle 44 to place the middle frame at the L-shaped hole 53 of the rotating disk 51.

[0036] (2) Start the drive motor 52 to rotate the rotating disk 51. The rotating disk 51 drives the middle frame to move in position. When the middle frame moves below the grinding roller 68, operate the linear module 12, the linear module 2 13 and the drive motor 67 to perform the grinding operation of the middle frame.

[0037] (3) The cylinder 65 drives the slider 64 to slide horizontally. The slider 64 drives the disc 62 to rotate at a certain angle through the connecting rod 66, thereby driving different grinding rollers 68 to first coarse and then fine grind, thus improving the grinding effect of the middle frame.

[0038] (4) After the middle frame is polished, the rotating disk 51 drives the middle frame to move in position, and the clamping mechanism 4 on the other side moves the middle frame to the conveyor belt 3 on the other side to discharge the middle frame. In this way, the fully automatic polishing of the middle frame is realized.
