Description

Technical Field

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

[0002] Laptops, also known as "notebooks", are also called laptop shells for the sake of convenience. Laptop shells are important structures that protect internal electronic components, and they also affect the overall appearance, feel and portability of the device. Depending on the material, laptop shells can be divided into many types, each with its own unique characteristics and advantages and disadvantages. Laptop shells include metal shells and plastic shells, but when these two shells are produced, the edges will have burrs due to cutting or stamping during the processing process. The burrs not only affect the appearance of the product and reduce the quality of the product, but also put the user at risk of being scratched or stabbed. Therefore, the laptop shell needs to be polished during the production process to eliminate burrs, but the current polishing method, whether it is manual or mechanical, will leave dust on the laptop shell after polishing. In order to prevent the attached dust from affecting the painting of the laptop shell, the dust on the polished laptop shell needs to be cleaned to avoid affecting subsequent processing. Therefore, the current polishing method will cause more dust to adhere to the notebook shell after polishing, and increase the process of manual cleaning of the attached dust, which not only reduces the production and processing efficiency of the notebook shell, but also increases the labor cost during production. Summary of the invention

[0003] The present invention aims to provide a polishing device for producing and processing a notebook shell, so as to solve the problem of dust adhering to the notebook shell after polishing.

[0004] To solve the above technical problems, the present invention provides the following technical solutions: a polishing device for the production and processing of notebook shells, comprising a polishing box and a dust removal mechanism, the polishing box comprising a box body and a box cover, the inner bottom of the box body is fixedly connected with a lifting mechanism, the top of the lifting mechanism is fixedly connected with a motor with an output shaft vertically upward, the output shaft of the motor is fixedly connected with a horizontal plate, the upper surface of the horizontal plate is fixedly connected with a plurality of suction cups, the suction cups are used to fix the notebook shell by sucking it by negative pressure; an avoidance hole is provided on the inner wall of the box body, a transverse movable rod is slidably connected in the avoidance hole, the end of the movable rod is fixedly connected with a transverse plate, the movable rod is sleeved with a spring, one end of the spring is fixedly connected to the inner wall of the box body, the other end of the spring is fixedly connected to the transverse plate, the transverse plate is fixedly connected with a polishing motor, the output shaft of the polishing motor passes through the transverse plate vertically downward and is fixedly connected with a polishing piece, the polishing piece is used to polish burrs at the edge of the notebook shell;

[0005] The dust removal mechanism includes a corona discharge type electrostatic generator, which is used to generate ion wind to cover the notebook shell, so that the notebook shell and the dust attached to it carry ions of the same charge; the polishing box is provided with an air inlet and a dust outlet, and the outside of the polishing box is fixedly connected to a negative pressure box, which is connected to the inside of the polishing box through the dust outlet, and the negative pressure box is connected to a negative pressure pump, and the air inlet pipe of the negative pressure pump is connected to the negative pressure box.

[0006] The working principle of the present invention is as follows: when in use, the notebook shell to be polished is placed on the blade suction cup, and the suction cup firmly absorbs the notebook shell through negative pressure, then the box cover is closed, and the lifting mechanism is started. At this time, the lifting mechanism starts to rise, and when the lifting mechanism rises, it drives the motor, the horizontal plate, and the notebook shell fixed on the horizontal plate by the suction cup to rise synchronously. When the edge of the notebook shell contacts the polishing piece, the lifting mechanism stops running. At this time, the polishing motor and the motor are started synchronously. When the polishing motor starts, it drives the polishing piece to rotate, and the edge of the notebook shell is polished when the polishing piece rotates. When the motor is running, it drives the horizontal plate to rotate in the horizontal direction. When the horizontal plate rotates, it drives the notebook shell to rotate through the suction cup. When the notebook shell rotates, the polishing piece polishes its circumference. During the rotation of the notebook, the sliding of the movable rod in the avoidance hole and the cooperation of the spring realize that the polishing piece is continuously held against the edge of the notebook shell. During the polishing process, the electrostatic generator and the negative pressure pump are started at the same time. When the electrostatic generator is running, ion wind is generated to cover the entire surface of the notebook shell, so that the notebook shell and the dust on the surface of the notebook shell carry electrons of the same charge. Therefore, under the effect of repulsion between charges of the same kind, the dust is separated from the notebook shell due to repulsion. When the negative pressure pump is running, the air in the negative pressure box is extracted to form a negative pressure. After the negative pressure is formed in the negative pressure box, the dust in the polishing box is absorbed through the dust outlet. During the vacuuming process, the polishing box is replenished with air through the air inlet, so that the dust in the polishing box can continue to flow into the negative pressure box with the air flow. After the polishing is completed, turn off the electrostatic generator, negative pressure pump, motor and polishing motor, open the box cover and take out the notebook shell.

[0007] Beneficial effects of the present invention:

[0008] 1. Through the lifting mechanism, the motor drives the horizontal plate to rotate, and the grinding motor drives the grinding piece to rotate, the edge of the notebook shell can be fully polished. This multi-axis linkage method not only improves the polishing efficiency, but also ensures the consistency of the polishing quality.

[0009] 2. The design of the movable rod and spring enables the grinding piece to automatically adjust the contact pressure according to the change of the shell shape, ensuring the stability and uniformity during the grinding process.

[0010] 3. The ion wind generated by the corona discharge electrostatic generator makes the outer shell and the dust on it carry the same charge, and the dust falls off naturally by the principle of electrostatic repulsion. This method can not only effectively remove fine particles, but also will not cause physical damage to the outer shell.

[0011] 4. When used with a negative pressure pump and a negative pressure box, the dust generated by grinding can be quickly removed to keep the working environment clean, while also preventing the dust from adhering to the outer casing again.

[0012] 5. The entire grinding process is carried out in a closed box, which reduces the emission of harmful dust into the air, protects the health of operators, and meets the requirements of modern industry for environmental protection.

[0013] Furthermore, a controller is included, and the lifting mechanism, motor, electrostatic generator, grinding motor and negative pressure pump are all connected to the controller by electrical signals. The purpose is to control the lifting mechanism, motor, electrostatic generator, grinding motor and negative pressure pump through the controller to achieve automatic control, reduce manual operation and save labor costs.

[0014] Furthermore, the lifting mechanism includes two electric lifting rods, and both of the two electric lifting rods are connected to the controller by electrical signals. The purpose is to use two electric lifting rods to ensure the horizontal lifting of the motor and facilitate control by the controller.

[0015] Furthermore, the polishing piece includes a circular polishing sheet and a cylindrical polishing column, the diameter of the polishing sheet is larger than the diameter of the polishing column, the center of the polishing sheet is fixedly connected to the output shaft of the polishing motor, and the polishing column is coaxially fixedly connected to the center of the lower surface of the polishing sheet. The purpose is that when the edge of the notebook shell contacts the circumferential surface of the polishing column and the surface contacts the lower surface of the polishing sheet, the circumferential surface of the notebook shell and the upper surface at the edge can be polished synchronously at the same time.

[0016] Furthermore, a contact switch is fixedly installed on the top of the box body, and the contact switch is connected to the controller by electrical signal. The purpose is that when the box cover is closed, the contact switch transmits the contact signal to the controller, and the controller controls the start-up of components such as the lifting mechanism, the motor, the electrostatic generator, the grinding motor and the negative pressure pump.

[0017] Furthermore, a vertically arranged filter screen is detachably connected to the negative pressure box, the dust outlet is located on the left side of the filter screen, and the air inlet pipe of the negative pressure pump is located on the right side of the filter screen. The purpose is to filter dust in the negative pressure box through the filter screen to prevent dust from entering the negative pressure pump and affecting the normal operation of the negative pressure pump.

A plurality of suction cups 12 are fixedly connected to the upper surface of the horizontal plate 11. An air pump is fixedly installed in the box body 4, and the air pipe of the air pump is connected to the plurality of suction cups 12. An avoidance hole is provided on the inner wall of the box body 4. A transverse movable rod 18 is slidably connected, and a transverse plate 16 is fixedly connected to the end of the movable rod 18. A spring 17 is sleeved on the movable rod 18. One end of the spring 17 is fixedly connected to the inner wall of the box body 4, and the other end of the spring 17 is fixedly connected to the transverse plate 16. A grinding motor 15 is fixedly connected to the transverse plate 16. The output shaft of the grinding motor 15 vertically passes through the transverse plate 16 downward and is fixedly connected to a grinding part. The grinding part includes a circular grinding sheet 14 and a cylindrical grinding column 13. The diameter of the grinding sheet 14 is larger than the diameter of the grinding column 13. The center of the grinding sheet 14 is fixedly connected to the output shaft of the grinding motor 15, and the grinding column 13 is coaxially fixedly connected to the center of the lower surface of the grinding sheet 14.

[0025] The dust removal mechanism includes a corona discharge type electrostatic generator 3, which is used to generate ion wind to cover the notebook shell, so that the notebook shell and the dust attached to it carry ions of the same charge; the polishing box is provided with an air inlet 2 and a dust outlet 7, and the outside of the polishing box is fixedly connected to a negative pressure box 9, the negative pressure box 9 is connected to the inside of the polishing box through the dust outlet 7, the negative pressure box 9 is connected to a negative pressure pump 10, the air inlet pipe of the negative pressure pump 10 is connected to the negative pressure box 9, and a vertically arranged filter screen plate 8 is detachably connected to the negative pressure box 9, the dust outlet 7 is located on the left side of the filter screen plate 8, and the air inlet pipe of the negative pressure pump 10 is located on the right side of the filter screen plate 8.

[0026] The lifting mechanism, the motor 6, the electrostatic generator 3, the grinding motor 15, the air pump and the negative pressure pump 10 are all connected to the controller via electrical signals.

[0027] The specific implementation process is as follows:

[0028] When in use, the notebook shell to be polished is placed on the blade suction cup 12, and the suction cup 12 forms a negative pressure through the air pump to firmly absorb the notebook shell, and then the box cover 1 is closed. When the box cover 1 is closed, the contact switch transmits the contact signal to the controller, and then the controller starts the two electric lifting rods 5, and then the electric lifting rods 5 begin to rise. When the electric lifting rods 5 rise, they drive the motor 6, the horizontal plate 11, and the notebook shell fixed on the horizontal plate 11 by the suction cup 12 to rise synchronously. When the edge of the notebook shell contacts the polishing piece, the electric lifting rod 5 stops running. At this time, the polishing motor 15 and the motor 6 are started synchronously. When the polishing motor 15 starts, it drives the polishing piece to rotate, and the edge of the notebook shell is polished when the polishing piece rotates. When the motor 6 is running, it drives the horizontal plate 11 to rotate horizontally. When the horizontal plate 11 rotates, it drives the notebook shell to rotate through the suction cup 12. When the notebook shell rotates, the grinding piece grinds its circumference. During the rotation of the notebook, the sliding of the movable rod 18 in the avoidance hole and the cooperation of the spring 17 realize that the grinding piece is continuously held against the edge of the notebook shell. After the notebook shell rotates one circle, the controller controls the motor 6 to run in the reverse direction, thereby driving the notebook shell to rotate in the reverse direction for one circle, and then rotates forward, so as to avoid the air pipe of the air pump from being entangled. During the grinding process, the electrostatic generator 3 and the negative pressure pump 10 are started at the same time. When the electrostatic generator 3 is running, it generates ion wind covering the entire surface of the notebook shell, so that the notebook shell and the dust on the surface of the notebook shell carry electrons of the same charge. Therefore, under the effect of the repulsion of charges of the same kind, the dust is separated from the notebook shell due to the repulsive force. When the negative pressure pump 10 is running, the air in the negative pressure box 9 is extracted to form a negative pressure. After the negative pressure is formed in the negative pressure box 9, the dust in the polishing box is absorbed through the dust outlet 7. During the dust suction process, the polishing box is replenished with air through the air inlet 2, so that the dust in the polishing box can continue to flow into the negative pressure box 9 with the air flow. After the polishing is completed, the electrostatic generator 3, the negative pressure pump 10, the motor 6 and the polishing motor 15 are turned off, and the box cover 1 is opened to take out the notebook shell.
