Description

Technical Field

[0001] This application relates to the field of polishing fixture technology, and in particular to a polishing fixture for the upper arm of a liquid crystal support. Background Technology

[0002] During the production of the LCD bracket upper arm, burrs will form on the outer side of the LCD bracket upper arm. In order to improve the appearance of the product, the LCD bracket upper arm is placed on a fixture and then the burrs are removed by a polishing machine, so that the surface of the LCD bracket upper arm remains smooth. However, after the LCD bracket upper arm is processed, burr waste will accumulate in the polishing fixture and inside the LCD bracket upper arm. When a lot of burr waste accumulates, it will affect the subsequent processing of the LCD bracket upper arm, thus reducing the processing efficiency of the LCD bracket upper arm. Utility Model Content

[0003] The purpose of this utility model is to provide a polishing fixture for the upper arm of a liquid crystal support, addressing the defects and shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The system includes a base frame, a first support, and two second supports. The first support and the two second supports are located on the base frame, with the first support positioned between the two second supports. The first support and the two second supports are arranged horizontally. Multiple placement slots are evenly distributed on the corresponding side walls of the first support and the second supports. A cleaning assembly is provided on the first support. The cleaning assembly includes a drive component, a sliding block, an air inlet pipe, and two air outlet pipes. The sliding block moves back and forth along the length of the first support. One end of the air inlet pipe is inserted into the sliding block. The two air outlet pipes are respectively inserted into the corresponding side walls of the sliding block and communicate with the inner end of the air inlet pipe. The outer ends of the two air outlet pipes face the space between the first support and the second supports. The drive component can drive the sliding block to slide on the first support.

[0006] Preferably, the driving component includes a drive motor, a lead screw, and a drive nut. The drive nut is disposed on the lower end face of the sliding block, the lead screw is threaded through the drive nut, and one end of the lead screw is disposed at the output end of the drive motor.

[0007] Preferably, an adjustment frame is placed on the upper end of the sliding block, and the two ends of the adjustment frame are respectively sleeved on the periphery of the two air outlet pipes.

[0008] Preferably, a guide rod is fixed to the upper end of the sliding block, and the side wall of the adjusting frame slides around the guide rod.

[0009] Preferably, the lower ends of the two second supports are respectively provided with unloading grooves.

[0010] Preferably, an adjusting cylinder is provided on the lower side of each end of the base frame, and the output end of the adjusting cylinder is connected to the second bracket.

[0011] Preferably, the side walls at both ends of the second bracket are respectively provided with waist-shaped grooves, and limit screws are provided in the waist-shaped grooves.

[0012] In summary, the beneficial technical effects of this application are as follows:

[0013] After the upper arm of the LCD bracket is processed by the polishing machine, the drive motor is started first. With the cooperation of the lead screw and the drive nut, the sliding block moves back and forth on the first bracket. At the same time, air is injected into the air inlet pipe and then blown out from the two air outlet pipes. This blows away the burrs and debris inside the upper arm of the LCD bracket. After the upper arm of the LCD bracket is removed, the drive motor continues to work. The air blown out from the air outlet pipes blows away the burrs and debris on the placement slot and the base frame. Then, the debris slides out from the unloading slot, thus maintaining the cleanliness of the polishing fixture and ensuring that the subsequent work of the polishing fixture is not affected.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] This application discloses a polishing fixture for the upper arm of a liquid crystal support.

[0020] Reference Figure 1 and Figure 2It includes a base frame 1, a first support 2 and two second supports 3. The two second supports 3 are located on both sides of the first support 2. The first support 2 and the two second supports 3 are arranged horizontally. Multiple placement slots 4 are evenly opened on both sides of the upper end of the first support 2 and the inner side of the upper end of the second support 3. The multiple placement slots 4 on the corresponding side of the first support 2 and the second support 3 are symmetrically opened.

[0021] Reference Figure 3 A cleaning component 5 is placed on the first bracket 2. The cleaning component 5 includes a driving component 6, a sliding block 7, an air inlet pipe 8, and two air outlet pipes 9. The driving component 6 includes a driving motor 10, a lead screw 11, and a driving nut 12. The sliding block 7 slides along its length above the first bracket 2. The driving nut 12 is fixed to the lower end face of the sliding block 7. The lead screw 11 is rotatably connected to the first bracket 2. The circumferential thread of the lead screw 11 is engaged with the driving nut 12. The driving motor 10 is fixed to one end of the first bracket 2. One end of the lead screw 11 is connected to the output end of the driving motor 10. One end of the air inlet pipe 8 is inserted into the side wall of the sliding block 7. One end of the two air outlet pipes 9 is inserted into the side wall of the sliding block 7 and communicates with the inner end of the air inlet pipe 8. The two air outlet pipes 9 are symmetrically arranged, and the outer end of the air outlet pipes 9 faces the space between the first bracket 2 and the second bracket 3.

[0022] Reference Figure 2 The lower end of the second bracket 3 is provided with a discharge groove 13, which is opened through on both sides. When the drive motor 10 is started, the sliding block 7 moves back and forth on the first bracket 2 under the cooperation of the lead screw 11 and the drive nut 12, while inflating the air inlet pipe 8 and blowing it out from the two air outlet pipes 9. This blows away the burrs and debris in the upper arm of the LCD bracket. After the upper arm of the LCD bracket is removed, the drive motor 10 continues to work, and the air blown out from the air outlet pipes 9 blows away the burrs and debris on the placement slot 4 and the base frame 1, and then slides out from the discharge groove 13.

[0023] Reference Figure 3 An adjusting frame 14 is placed above the sliding block 7. The vertical cross-section of the adjusting frame 14 is U-shaped. The two ends of the adjusting frame 14 are respectively fitted onto the outer periphery of the air outlet pipe 9. A guide rod 15 is vertically fixed at the upper end of the sliding block 7. A guide hole 16 is opened on the side wall of the adjusting frame 14, and the guide rod 15 passes through the guide hole 16. Under the action of gravity, the adjusting frame 14 can bend the air outlet pipe 9 so that the outer end of the air outlet pipe 9 is aligned with the placement groove 4 of the first bracket 2. As the air force blown in by the air inlet pipe 8 gradually increases, the air outlet pipe 9 will gradually rise, so that the outer end of the air outlet pipe 9 will move closer to the second bracket 3.

[0024] Reference Figure 2An adjusting cylinder 17 is fixed to the lower side of each end of the base frame 1, and the two adjusting cylinders 17 are placed opposite each other. A connecting plate 20 is fixed to the outer side of the second bracket 3, and the lower end of the connecting plate 20 is connected to the output end of the adjusting cylinder 17. The upper end face of each end of the second bracket 3 is provided with a waist-shaped groove 18, and the length direction of the waist-shaped groove 18 is perpendicular to the length direction of the second bracket 3. A limit screw 19 is placed in the waist-shaped groove 18, and the lower end of the limit screw 19 is threaded and fixed in the upper end face of the base frame 1. The adjusting cylinder 17 can drive the second bracket 3 away from or closer to the first bracket 2 through the connecting plate 20, thereby facilitating the disassembly or installation of the upper arm of the LCD bracket.
