Description

Technical Field

[0001] The invention relates to the technical field of notebook computer processing equipment, and in particular to a positioning device used for notebook computer processing. Background Art

[0002] Laptop, also known as portable computer, handheld computer, PDA or laptop, is a small and portable personal computer. Laptop consists of aluminum alloy shell, processor and motherboard, among which aluminum alloy shell is an important part of laptop, which can effectively protect the electronic components inside the laptop and prevent them from external impact and damage.

[0003] In the prior art, the manufacture of aluminum alloy shells usually adopts stamping, die-casting or CNC integrated forming and other processes, and then needs to undergo surface treatment. After the aluminum alloy shells undergo surface treatment processes such as sandblasting and anodizing, they can present different colors and textures to meet consumers' demand for aesthetics. When sandblasting the aluminum alloy shell, a positioning tool is required to clamp it from the aluminum alloy shell so that it remains fixed during the processing and plays a positioning role. In the prior art, the clamp is usually driven by a screw rod, that is, the sliding direction of the clamp is limited by the slide groove, and the clamp is driven to move and clamp by rotating the screw rod. However, this method is relatively cumbersome, time-consuming and labor-intensive, and reduces work efficiency. In addition, during the sandblasting process, the polishing sand is also very easy to fall into the slide groove to cause blockage, making the clamp slide unsmoothly. Summary of the invention

[0004] The present invention is intended to provide a positioning device for processing a notebook computer, so as to solve the problem in the prior art that polishing sand falls into a slide groove, causing a fixture to slide unsmoothly.

[0005] In order to solve the above problems, the present invention provides the following technical solutions:

[0006] A positioning device for processing laptop computers comprises a frame, wherein the frame is fixedly provided with a fixed block with a cavity inside, a slide groove is provided on the side of the fixed block, a sand discharge groove is provided on the bottom of the fixed block, and the slide groove and the sand discharge groove are both connected with the cavity; the fixed block is fixedly provided with a motor, the movable end of the motor drives a rotating disk located in the cavity, the outer circumference of the rotating disk is symmetrically provided with driving blocks, the thickness of the driving blocks gradually increases in a clockwise direction, the slide groove is symmetrically slidably connected with a clamping plate abutting the corresponding driving block, a spring is fixedly provided between the clamping plate and the slide groove, the fixed block is also fixedly provided with a cylinder, the movable end of the cylinder drives a sealing cover that closes the slide groove, the bottom of the sealing cover is provided with a groove for accommodating the clamping plate, and the sealing cover is provided with a plurality of first nozzles that spray toward the slide groove.

[0007] Working principle and beneficial effects of the present invention:

[0008] In this solution, a motor drives the rotating disk to rotate, and the rotating disk drives the driving block to rotate synchronously. The thickness change of the driving block is used to adjust the degree of extrusion of the corresponding clamping plate by the driving block, and cooperates with the compression spring to adjust the distance between the clamping plates on both sides, so that the aluminum alloy shell is clamped between the clamping plates for processing. When the sandblasting operation is completed, the reverse rotation of the motor releases the extrusion of the clamping plates on both sides, and the compressed spring returns to pull the clamping plates back to the initial position. At this time, the driving sealing cover is started to move downward, and the clamping plates are clamped into the grooves, thereby forming an enclosed space. The first nozzle sprays high-pressure gas toward the slide groove and the inside of the cavity, and blows out the polishing sand inside the cavity, on the slide groove, and on the clamping plates located inside the sealing cover and inside the cavity through the sand discharge groove, thereby achieving cleaning.

[0009] This solution firstly drives the rotating disk to rotate by a motor to quickly adjust the distance between the two side clamps, which has the advantage of fast adjustment. Secondly, high-pressure air is sprayed through the sealing cover, the groove and multiple first nozzles to blow the polishing sand outward through the sand discharge groove, thereby achieving cleaning, thereby solving the problem in the prior art that the polishing sand falls into the slide groove and causes blockage, making the fixture slide unsmoothly.

[0010] Optimally, the clamp is provided with a clamping groove. The aluminum alloy shell is clamped into the clamping grooves on the clamping plates on both sides, thereby fixing the aluminum alloy shell, and the polishing sand will not fall into the clamping groove due to the aluminum alloy shell blocking the sandblasting operation.

[0011] Preferably, the motor is a servo motor, which has the characteristic of precise rotation, thereby precisely controlling the rotation angle of the rotating disk.

[0012] Optimally, the size of the groove matches the size of the clamping plate. This optimization solution allows the clamping plate to completely seal the groove, thereby forming a completely enclosed space in cooperation with the sealing cover.

[0013] Optimally, a plurality of second nozzles are fixedly arranged on the top of the cavity. When the first nozzle has finished spraying, the second nozzle blows air into the cavity to achieve more thorough cleaning to prevent polishing sand from remaining.

[0014] Optimally, the frame is provided with universal self-locking wheels. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is further described in detail through specific implementation methods:

[0020] The reference numerals in the drawings of the specification include: a fixed block 1, a sand discharge groove 2, a driving block 3, a rotating disk 4, a motor 5, a spring 6, a sealing cover 7, a clamping plate 8, a first nozzle 9, a slide groove 10, an aluminum alloy shell 11, a cylinder 12, and a second nozzle 13.

[0021] In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0022] Embodiment: A positioning device for processing a notebook computer includes a frame (not shown in the figure), the frame is fixed with a fixing block 1 having a cavity inside, such as Figure 2 As shown, a slide groove 10 is provided on the side of the fixed block 1, and a sand discharge groove 2 is provided at the bottom of the fixed block 1. The slide groove 10 and the sand discharge groove 2 are both connected to the cavity; a motor 5 is fixedly provided on the fixed block 1, and the movable end of the motor 5 drives a rotating disk 4 located in the cavity. The outer periphery of the rotating disk 4 is symmetrically provided with a driving block 3, and the thickness of the driving block 3 gradually increases in the clockwise direction. The slide groove 10 is symmetrically slidably connected with a clamping plate 8 abutting against the corresponding driving block 3, and a spring 6 is fixedly provided between the clamping plate 8 and the slide groove 10, as shown in FIG. Figure 3 As shown, the fixed block 1 is also fixedly provided with a cylinder 12, and the movable end of the cylinder 12 drives a sealing cover 7 with a closed slide groove 10. The sealing cover 7 is a square box body with a closed bottom and an open left side. The bottom of the square box is provided with a groove for accommodating a splint 8, and the size of the splint 8 matches the size of the groove. The sealing cover 7 is fixedly provided with a plurality of first jet heads 9 that spray toward the slide groove 10, and a plurality of second jet heads 13 are fixedly provided on the top of the cavity. The first jet head 9 and the second jet head 13 are both supplied with high-pressure gas by an external air pump.

[0023] like Figure 2As shown, in this solution, the motor 5 drives the rotating disk 4 to rotate counterclockwise, and the rotating disk 4 drives the driving block 3 to rotate synchronously. The thickness variation of the driving block 3 is used to adjust the degree of extrusion of the corresponding clamping plate 8 by the driving block 3, and the compression spring 6 is used to adjust the distance between the clamping plates 8 on both sides, so that the aluminum alloy shell 11 is clamped between the clamping plates 8 for processing. Figure 1 and Figure 4 As shown, after the sandblasting operation is completed, the motor 5 rotates clockwise, and the driving block 3 rotates clockwise to release the squeezing of the two side clamps 8. The compressed spring 6 recovers and pulls the clamp 8 back to the initial position. At this time, the driving sealing cover 7 is started to move downward, and the clamp 8 is stuck in the groove. The sealing cover 7 and the clamp 8 form a relatively closed space. The first nozzle 9 sprays high-pressure gas toward the slide groove 10 and the inside of the cavity, and the polishing sand inside the cavity, on the slide groove 10, and on the clamp 8 located inside the sealing cover 7 and the inside of the cavity is blown out through the sand discharge groove 2. When the first nozzle 9 finishes spraying, the second nozzle 13 blows air into the cavity to blow out the polishing sand remaining on the rotating disk 4 and the driving block 3, so as to achieve more thorough cleaning to prevent polishing sand from remaining.
