Description

Technical Field

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

[0002] LCD bracket bases are generally formed by injection molding. Typically, the bottom of the LCD bracket base is located between the upper and lower mold plates of the injection mold, resulting in burrs at the bottom. To improve the aesthetics of the LCD bracket base, the bottom is polished on a polishing machine. However, when polishing multiple LCD bracket bases, the operator needs to sequentially bring the bottom of each base into contact with the polishing machine, resulting in low polishing efficiency. Utility Model Content

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

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

[0005] It includes multiple mounting blocks and a material tray. The mounting blocks are located on the material tray and are arranged horizontally and parallel to each other. Multiple limiting grooves are evenly opened on the corresponding side walls of two adjacent mounting blocks along the length direction. The liquid crystal bracket base is inverted and embedded in the corresponding two limiting grooves.

[0006] Preferably, a plurality of push rods are evenly connected to the upper end surface of the material tray, and each of the push rods corresponds to a liquid crystal bracket base above the material tray. A push plate is provided below the material tray, and the lower ends of the plurality of push rods are provided on the upper end surface of the push plate. A push cylinder is provided between the material tray and the push plate, and the push cylinder drives the push plate to move up and down.

[0007] Preferably, a movable frame slides horizontally on the material tray, and a plurality of suction pipes are evenly arranged on the movable frame. The lower end of the suction pipe is located below the movable frame and between two adjacent mounting blocks.

[0008] Preferably, rollers are rotatably connected to the corresponding two inner sides of the movable frame, and the rollers slide and roll on the upper side of the material tray.

[0009] Preferably, the two outer side walls of the movable frame are respectively provided with lifting cylinders vertically upward, the output ends of the two lifting cylinders are provided with lifting plates, and the plurality of suction pipes are evenly fixed inside the side wall of the lifting plate.

[0010] Preferably, the two ends of the material tray are respectively provided with limit blocks, and the movable frame can abut against the two limit blocks respectively.

[0011] Preferably, the side wall of the movable frame is provided with a drive rod.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When multiple LCD bracket bases need to be polished, the multiple LCD bracket bases are first placed in the corresponding two limiting grooves of two adjacent mounting blocks. Then the polishing head of the polishing machine moves above the multiple LCD bracket bases to polish the bottom of the LCD bracket bases, thereby improving the polishing efficiency of processing LCD bracket bases.

[0014] 2. When the bottom of the LCD bracket base is polished, first hold the drive rod, and then drive the moving frame to move along the length of the mounting block, so that the lower ends of the multiple suction tubes of the moving frame will sequentially suck up the burrs inside the bottom of the LCD bracket base, thereby keeping the inside of the LCD bracket base clean.

[0015] 3. After the LCD bracket base is processed, the push cylinder pulls the push plate upward, which in turn moves multiple push rods upward, thereby pushing the LCD bracket base out of the corresponding two limit slots, making it easy to remove the LCD bracket base from between two adjacent mounting blocks.

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

[0020] This application discloses a polishing fixture for a liquid crystal bracket base.

[0021] Reference Figure 1 and Figure 2, including five mounting blocks 1 and a tray 2. The five mounting blocks 1 are located on the tray 2. There are multiple support rods 3 between the mounting blocks 1 and the tray 2. The upper ends of the support rods 3 are fixed to the lower end surfaces of the mounting blocks 1, and the lower ends of the support rods 3 are fixed to the upper end surface of the tray 2. Four limiting grooves 4 are evenly formed in the corresponding side walls of two adjacent mounting blocks 1 along the length direction, and the corresponding four limiting grooves 4 are formed correspondingly. The vertical cross-section of the LCD bracket base is in a "convex" shape. The LCD bracket base is placed upside down, and both sides of the bottom of the LCD bracket base are respectively embedded and placed in two corresponding limiting grooves 4. A plurality of LCD bracket bases are sequentially placed in the two corresponding limiting grooves 4 of two adjacent mounting blocks 1. Then, the polishing head of the polishing machine moves above the plurality of LCD bracket bases, so as to polish the bottom of the LCD bracket base.

[0022] A plurality of through holes 5 are evenly formed in the upper end surface of the tray 2. A push rod 6 is inserted through the through hole 5. A push plate 7 is horizontally placed below the tray 2. The lower ends of the plurality of push rods 6 are fixed to the upper end surface of the push plate 7. There are two push cylinders 8 between the push plate 7 and the tray 2. The upper ends of the push cylinders 8 are fixed to the lower end surface of the tray 2, and the lower end surfaces of the push cylinders 8 are fixed to the upper end surface of the push plate 7. The push cylinders 8 pull the push plate 7 to move upward, and at the same time带动多个顶杆6上移,从而将液晶支架底座从对应的两个限位槽4内顶出,随后方便将液晶支架底座从相邻两个安装块1之间取出。

[0023] A moving frame 9 slides horizontally above the tray 2. The vertical cross-section of the moving frame 9 is in a "U" shape. The two ends of the moving frame 9 are located on the corresponding two sides of the tray 2. Clamping blocks 10 are integrally provided at the two ends of the moving frame 9. The upper side walls of the clamping blocks 10 abut against the lower end surface of the tray 2. Two rollers 11 are respectively rotatably connected to the corresponding two inner side walls of the moving frame 9.

[0024] Limit blocks 12 are respectively fixed to the two sides below the two ends of the tray 2 by bolts. The limit blocks 12 and the clamping blocks 10 correspond to each other. Under the restriction of the two groups of limit blocks 12, the moving frame 9 can move back and forth above the tray 2.

[0025] Lifting cylinders 13 are respectively vertically installed on the corresponding two outer side walls of the moving frame 9. A lifting plate 14 is fixed to the output ends of the two lifting cylinders 13. Four suction pipes 15 are evenly inserted and fixed along the length direction of the side wall of the lifting plate 14. The upper ends of the four suction pipes 15 converge together and are connected to a suction pump. The suction pipes 15 are inserted and slide in the side wall of the moving frame 9. The lower ends of the suction pipes 15 are in a flared shape. The moving frame 9 moves along the length direction of the mounting block 1, so that the lower ends of the plurality of suction pipes 15 of the moving frame 9 sequentially suck the burrs inside the bottom of the LCD bracket base, so as to keep the inside of the LCD bracket base clean.

[0026] A drive rod 16 is fixed to the outer wall of the mobile frame 9. When the mobile frame 9 needs to be moved horizontally, the operator can hold the drive rod 16 to facilitate the movement of the mobile frame 9 back and forth.
