Description

Technical Field

[0001] This utility model relates to a polishing machine, and more particularly to a plasma polishing machine for processing crystal balls. Background Technology

[0002] A crystal ball is a spherical decorative item made of crystal. During crystal ball production, polishing is necessary to achieve a smoother surface and better visual effect. Currently, common crystal ball polishing methods involve using a fixture to move the crystal ball to the polishing head, as disclosed in patent publication number "CN218697010U". This process requires continuous spraying of cooling water and constant adjustment of the angle between the fixture and the polishing head, making the entire process complex and time-consuming for each crystal ball, resulting in low overall polishing efficiency. Therefore, existing crystal ball polishing equipment suffers from low efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a plasma polishing machine for processing crystal balls.

[0004] This invention has the advantage of high polishing efficiency.

[0005] The technical solution of this utility model is as follows: A plasma polishing machine for processing crystal balls includes a polishing chamber. A liquid outlet pipe is provided on the bottom surface of the polishing chamber, and a first one-way valve is installed on the liquid outlet pipe. A liquid inlet pipe is provided on the top surface of the polishing chamber, and a second one-way valve is installed on the liquid inlet pipe. A discharge port is provided on one side of the liquid inlet pipe on the top surface of the polishing chamber, and a sealing cap is rotatably installed on the discharge port. An upper magnetic plate and a lower magnetic plate are installed symmetrically arranged inside the polishing chamber, with opposite magnetic poles. A translational reciprocating device is provided between the upper and lower magnetic plates on the inner wall of the polishing chamber, and the translational reciprocating device is equipped with a discharge valve. The crystal ball is placed in a feeding seat. When the reciprocating device moves the crystal ball between the upper and lower magnetic plates, the magnetic field between the upper and lower magnetic plates accelerates and guides the plasma in the plasma polishing liquid fed into the polishing chamber. This allows the plasma to collide with the surface of the crystal ball more quickly and frequently, thereby improving the overall polishing efficiency. A second one-way valve is installed on the inlet pipe, and a first one-way valve is installed on the outlet pipe. This allows the replenishment and discharge of polishing liquid to be carried out separately or simultaneously as needed, which is convenient for use. Moreover, the one-way valve can effectively prevent backflow.

[0006] In the aforementioned plasma polishing machine for crystal ball processing, multiple upper magnetic plates are provided, and the magnetic poles of every two adjacent upper magnetic plates are arranged in opposite directions; multiple lower magnetic plates are also provided, and the magnetic poles of every two adjacent lower magnetic plates are also arranged in opposite directions; the magnetic poles of the multiple upper and lower magnetic plates and every two adjacent upper and lower magnetic plates are in opposite directions, thereby forming a space with a changing magnetic field between all the upper and lower magnetic plates, which allows the plasma in the polishing liquid to move in a curved path, increases the movement path of the plasma, and thus increases the number of times the plasma is applied to the surface of the crystal ball, further accelerating the polishing efficiency.

[0007] In the aforementioned plasma polishing machine for crystal ball processing, mounting bases are provided on the inner sidewall of the polishing box at positions corresponding to the upper and lower magnetic plates. Each mounting base has multiple evenly distributed mounting slots with open top surfaces. Two symmetrically arranged elastic clips are provided at the opening of each mounting slot. The cooperation between the elastic clips and the mounting slots allows for the fixation of the upper and lower magnetic plates, ensuring structural stability and facilitating their installation.

[0008] In the aforementioned plasma polishing machine for processing crystal balls, the translation reciprocating device includes a ball screw, the end of which is connected to a servo motor; the servo motor is fitted with a protective frame; a translation seat is slidably mounted on the ball screw; a slot is provided on the side of the translation seat, and a locking block is engaged in the slot, with the locking block fixedly mounted on the feeding seat.

[0009] In the aforementioned plasma polishing machine for crystal ball processing, both ends of the ball screw are provided with limiting components, and each limiting component has a piezoelectric sensor on its side facing the other limiting component. Both piezoelectric sensors are electrically connected to a controller, which is electrically connected to a servo motor. By utilizing the piezoelectric sensors in conjunction with the translational seat, limiting and positioning operations can be performed at both ends of the translational seat's movement path. This facilitates the controller in controlling whether the servo motor rotates forward or backward, thereby controlling the movement of the feeding seat, further simplifying use and improving accuracy.

[0010] In the aforementioned plasma polishing machine for crystal ball processing, sealing strips are attached to both inner sidewalls of the slot, and a first magnet is installed on the inner bottom surface of the slot; a second magnet is provided on the block to cooperate with the first magnet; by utilizing the mutual attraction between the first magnet and the second magnet, and in conjunction with the sealing strips, the friction between the inner sidewall of the slot and the block is increased, thereby increasing the tightness of the engagement between the slot and the block, which allows the material feeding seat to be more stably installed on the translation seat, thus improving the stability of the structure.

[0011] In the aforementioned plasma polishing machine for crystal ball processing, a filter box is provided on one side of the polishing box, and multiple evenly distributed mesh plates are arranged inside the filter box; filter cotton is arranged between each pair of adjacent mesh plates; the liquid outlet pipe and the liquid inlet pipe are both connected to the filter box; the filter box can be used to filter the discharged polishing liquid, thereby realizing the reuse of the polishing liquid and reducing the polishing cost.

[0012] Compared with existing technologies, this utility model improves existing crystal ball polishing equipment. By installing an upper magnetic plate and a lower magnetic plate inside the polishing chamber, and a reciprocating translational device between the upper and lower magnetic plates to move the crystal ball horizontally, the magnetic field between the upper and lower magnetic plates accelerates and guides the plasma in the plasma polishing solution fed into the polishing chamber. This allows the plasma to impact the surface of the crystal ball more quickly and frequently, thereby improving the overall polishing efficiency. Simultaneously, by installing an inlet pipe and an outlet pipe, with a second one-way valve on the inlet pipe and a first one-way valve on the outlet pipe, the replenishment and discharge of the polishing solution can be carried out separately or simultaneously as needed, facilitating use. Furthermore, the one-way valves effectively prevent backflow.

[0013] Furthermore, this invention also incorporates multiple upper and lower magnetic plates, with the magnetic poles of any two adjacent upper and lower magnetic plates facing opposite directions. This creates a space with a changing magnetic field between all the upper and lower magnetic plates, allowing the plasma in the polishing fluid to move in a curved path. This increases the plasma's movement path and the number of times the plasma is applied to the surface of the crystal ball, further accelerating the polishing efficiency. Additionally, the mounting base has multiple mounting slots, each with an elastic retainer at its opening. The interplay between the elastic retainer and the mounting slot further enhances the polishing efficiency. The design allows for the fixing of the upper and lower magnetic plates, ensuring structural stability and facilitating their installation. A slot on the translation seat, combined with a locking block on the feeding seat, allows for the disassembly and assembly of the feeding seat and the translation seat, simplifying replacement and maintenance of the feeding seat. This makes it suitable for polishing crystal balls of different sizes, increasing its flexibility. Limiting components with piezoelectric sensors at both ends of the ball screw, working in conjunction with the translation seat, allow for precise control of the translation seat's movement. Limiting and positioning functions at both ends of the moving path facilitate the controller's control of the servo motor's forward or reverse rotation, thereby controlling the movement of the feeding seat and further simplifying its use. Furthermore, using piezoelectric sensors, compared to non-contact sensors, not only effectively avoids the impact of polishing fluid on measurement accuracy but also avoids the decrease in detection accuracy or increase in error that occurs with non-contact sensors after prolonged use, improving overall precision. By incorporating a first magnet in the slot and a second magnet on the block, the mutual attraction between the first and second magnets, combined with a sealing strip, increases the friction between the inner wall of the slot and the block, increasing the tightness of the connection and allowing the feeding seat to be more stably installed on the translational seat, thus improving structural stability. A filter box between the inlet and outlet pipes filters the discharged polishing fluid, enabling its reuse and reducing polishing costs. The mesh plate fixes the position of the filter cotton, further enhancing structural stability. Therefore, this utility model not only improves the efficiency of polishing, but also has the advantages of being easy to use, highly flexible in use, highly stable in structure, and easy to maintain.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] Example. A plasma polishing machine for processing crystal balls, configured as follows: Figures 1 to 6 As shown, the polishing box 1 includes a liquid outlet pipe 2 on the bottom surface of the polishing box 1, and a first one-way valve 3 installed on the liquid outlet pipe 2; a liquid inlet pipe 4 is provided on the top surface of the polishing box 1, and a second one-way valve 5 is installed on the liquid inlet pipe 4; a discharge port 6 is provided on one side of the liquid inlet pipe 4 on the top surface of the polishing box 1, and a sealing cover 7 is rotatably installed on the discharge port 6; an upper magnetic plate 8 and a lower magnetic plate 9 are installed inside the polishing box 1, which are arranged symmetrically, and the magnetic poles of the upper magnetic plate 8 and the lower magnetic plate 9 are opposite; a translational reciprocating device is provided between the upper magnetic plate 8 and the lower magnetic plate 9 on the inner wall of the polishing box 1, and a discharge seat 10 for placing crystal balls is provided on the translational reciprocating device.

[0023] Multiple upper magnetic plates 8 are provided, and the magnetic poles of every two adjacent upper magnetic plates 8 are arranged in opposite directions; multiple lower magnetic plates 9 are also provided, and the magnetic poles of every two adjacent lower magnetic plates 9 are also arranged in opposite directions; mounting seats 11 are provided on the inner side wall of the polishing box body 1 at positions corresponding to the upper magnetic plates 8 and lower magnetic plates 9, and multiple evenly distributed mounting slots 12 with open top surfaces are provided on the mounting seats 11; two symmetrically arranged elastic clips 13 are provided at the opening of each mounting slot 12; the translation reciprocating device includes a ball screw 14, and a servo motor 15 is connected to the end of the ball screw 14; a protective frame 16 is fitted over the servo motor 15; a translation seat 17 is slidably mounted on the ball screw 14; a slot 18 is provided on the side of the translation seat 17, and a clip 19 is engaged in the slot 18. The clamping block 19 is fixedly installed on the feeding seat 10; both ends of the ball screw 14 are provided with limiting members 20, and each limiting member 20 is provided with a piezoelectric sensor 21 on the side facing the other limiting member 20; both piezoelectric sensors 21 are electrically connected to a controller 22, and the controller 22 is electrically connected to the servo motor 15; both inner sidewalls of the slot 18 are fitted with sealing strips 23, and a first magnet 24 is installed on the inner bottom surface of the slot 18; the clamping block 19 is provided with a second magnet 25 that cooperates with the first magnet 24; a filter box 26 is provided on one side of the polishing box 1, and multiple evenly distributed mesh plates 27 are provided in the filter box 26; filter cotton 28 is provided between each two adjacent mesh plates 27; the liquid outlet pipe 2 and the liquid inlet pipe 4 are both connected to the filter box 26.

[0024] Working principle: During the polishing process, the entire device is first connected to an external safe mains power supply, which powers on the controller 22 and the piezoelectric sensor 21 (the controller 22 used in this invention can be a programmable controller such as FX2C-20MRD, Cortex-R8, or Cortex-M7; the piezoelectric sensor 21 can be a model such as Y-YD-7051, CYB15, or CYZ102); then the crystal ball to be polished is placed on the feeding seat 10, and the sealing cover 7 is opened, and the crystal ball is fed through the feeding port 6. The ball feeding seat 10 is placed into the polishing box 1 and moved towards the translation seat 17. During the movement, the locking block 19 on the feeding seat 10 is aligned with the locking groove 18 on the translation seat 17, so that the locking block 19 enters the locking groove 18. The feeding seat 10 is installed on the translation seat 17 by the locking effect between the locking groove 18 and the locking block 19. At the same time, due to the setting of the first magnet 24 on the locking groove 18 and the second magnet 25 on the locking block 19, the attraction force between the first magnet 24 and the second magnet 25 can further increase the stability of the connection between the feeding seat 10 and the translation seat 17, ensuring the stability of use.

[0025] After the discharge seat 10 is in place, ensure the first one-way valve 3 is closed and open the second one-way valve 5. Input polishing liquid into the inlet pipe 4 through the external polishing liquid supply equipment until the polishing liquid completely submerges the upper magnetic plate 8, ensuring a certain distance between the liquid level and the discharge port 6. Then close the second one-way valve 5, cover with the sealing cap 7, and then control the servo motor 15 to start forward. After the servo motor 15 starts forward, it will drive the ball screw 14 to rotate. During the rotation of the ball screw 14, it will drive the translation seat 17 to move horizontally along the ball screw 14, allowing the translation seat 17 to move from one end of the ball screw 14 to the other. During the movement of the translation seat 17, it will drive the discharge seat... 10 and the crystal ball move; as the translation seat 17 moves, it will drive the feeding seat 10 and the crystal ball into the space between the upper magnetic plate 8 and the lower magnetic plate 9. Due to the magnetic force between the upper magnetic plate 8 and the lower magnetic plate 9, the plasma in the polishing fluid will be accelerated, allowing the plasma to quickly collide with the surface of the crystal ball. At the same time, because there are multiple upper magnetic plates 8 and lower magnetic plates 9, and the magnetic poles of every two adjacent upper magnetic plates 8 and every two adjacent lower magnetic plates 9 are set in opposite directions, the change in magnetic field can make the plasma move in multiple directions, and can also realize the transformation from linear motion to curvilinear motion, thereby increasing the number of collisions between the plasma and the surface of the crystal ball, and further improving the polishing efficiency; when the translation seat 17 drives the feeding seat When the ball and crystal ball move through the upper magnetic plate 8 and lower magnetic plate 9 to the end of the ball screw 14, the translation seat 17 will contact the limit member 20 and the piezoelectric sensor 21 on the limit member 20. At this time, the piezoelectric sensor 21 will generate an electrical signal to the controller 22. After receiving the electrical signal sent by the piezoelectric sensor 21, the controller 22 will control the servo motor 15 to start in reverse, so that the ball screw 14 drives the translation seat 17 to move back to the initial position of the translation seat 17. This allows the feeding seat 10 to carry the crystal ball back between the upper magnetic plate 8 and lower magnetic plate 9 for accelerated polishing, ensuring the polishing effect. After the translation seat 17 carries the feeding seat 10 and the crystal ball back to the initial position, it will contact the limit member on the corresponding side again. When the piezoelectric sensor 21 on component 20 comes into contact, the controller 22 receives the electrical signal sent by the piezoelectric sensor 21 again. At this time, the controller 22 will control the servo motor 15 to stop, so that the feeding seat 10 stops moving, and the entire polishing process ends. Finally, the first one-way valve 3 is opened to discharge the polishing liquid in the polishing box 1. The discharged polishing liquid will enter the filter box 26 through the liquid outlet pipe 2 and undergo multiple filtration processes through multiple mesh plates 27 and filter cotton 28 to filter out impurities in the polishing liquid. The filtered polishing liquid will then be reused through the liquid inlet pipe 4, which is more energy-efficient. At the same time, after the polishing liquid is discharged, the sealing cover 7 can be opened to remove the feeding seat 10 and the crystal ball on the feeding seat 10 that has completed the polishing work.
