Description

Technical Field

[0001] The present invention relates to the technical field of linear motors, and in particular to a linear motor with a vibration elimination function. Background Art

[0002] A linear motor is a transmission device that converts electrical energy directly into mechanical energy of linear motion without any intermediate conversion mechanism. It is also called a linear motor, linear motor, linear motor, or push rod motor. After being powered on, this motor can directly generate linear motion, so it is particularly suitable for occasions that require linear motion. Compared with traditional rotary motors, linear motors have the characteristics of high speed, high response, high precision, and direct drive, and are widely used in the field of industrial automation.

[0003] Commonly used linear motors may vibrate during use due to various reasons, resulting in position and processing accuracy errors during object transportation and processing. When the placement table of the linear motor has an uneven load, the placement table will vibrate slightly when moving. However, common linear motors are unable to accurately monitor the vibration and amplitude of the placement table during use, and cannot perform vibration elimination in a timely manner when the placement table vibrates. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a linear motor with a vibration elimination function.

The fixing plates are slidably installed inside the sliding holes, and the bottom ends of the fixing plates are located inside the fixing grooves. A support rod is installed on one side of the bottom end of the fixing plate close to the inner wall of the fixing groove, and a roller is rotatably installed on the outer wall of the support rod.

[0009] Preferably, a plurality of springs are installed at the inner bottom of the fixing groove in the length direction, the top of the spring is installed at the bottom of the magnet plate, guide grooves are opened on the inner walls at both ends of the fixing groove, guide blocks are installed at both ends of the magnet plate, and the two guide blocks are respectively slidably installed inside the two guide grooves.

[0010] Preferably, adjustment grooves are opened on the inner walls on both sides of the placement groove in the length direction, electric sliders are installed on both sides of the placement plate, the electric sliders are slidably installed inside the adjustment grooves, and positioning plates are installed at both ends of the placement table.

[0011] Preferably, a groove is opened in the inner bottom of the casing in the length direction, a stator is installed at the inner bottom of the groove, the stator is located below the mover, side covers are installed at both ends of the casing, limiting plates are installed on the opposite surfaces of the two side covers, and the bottom end of the limiting plate abuts against the inner bottom of the groove.

[0012] Preferably, a laser positioning sensor matching the positioning plate is installed on the top side of the limit plate, and bumpers are installed on both ends of the side of the side cover. The two bumpers are respectively located on both sides of the limit plate, and the bottom end of the bumper abuts against the inner bottom of the casing.

[0013] Preferably, sliding grooves are provided on both sides of the mover in the length direction, installation grooves are provided at both ends of the inner wall of the sliding groove, guide rails are installed on the inner walls of both sides of the casing in the length direction, and the middle end of the guide rail is slidably installed inside the sliding groove.

[0014] Preferably, a sliding block is installed on the inner wall of the installation groove, and one end of the sliding block away from the inner wall of the installation groove is slidably installed on the outer wall of the guide rail.

One end of the screw hole passes through the end faces of the protective shell and the side cover, and the internal threads of the screw holes are installed with fixing bolts.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the object located on the top of the placement plate presses down the top of the Hall sensor through the placement plate, and the Hall sensor can detect the stress conditions at different positions on the top of the Hall sensor. When the pressures at both ends of the top of the Hall sensor are different, the electric slider drives the placement plate to move inside the placement slot on the top of the placement table. The Hall sensor can detect the stress conditions at different positions on the top in real time until the stress conditions at different positions on the top of the Hall sensor are the same. The placement position of the object on the top of the placement plate can be adjusted during use. When the staff needs to place and move irregular objects, the placement table can be prevented from shaking or vibrating slightly due to uneven load during movement, which can improve the stability of the objects during movement during use.

[0018] 2. In the present invention, the staff can control the magnetic field strength of the electromagnet sheet by adjusting the current passing through the electromagnet sheet. When the magnetic field strength of the electromagnet sheet is high, the magnet plate can move down and disconnect from the roller. When the placement table vibrates on both sides while moving, the staff controls the magnetic field strength of the electromagnet sheet to make the spring push the magnet plate to move up, and according to the vibration amplitude on both sides of the placement table, the top of the magnet plate and the inner wall of the upper limit groove on the roller are slightly abutted against each other. The squeezing pressure between the magnet plate and the inner wall of the limit groove on the roller is adjusted according to the vibration amplitude on both sides of the placement table. When both sides of the placement table vibrate, the two magnet plates can support the two sides of the placement table respectively, and at the same time, a number of rollers on both sides of the placement table roll on the top of the magnet plate to eliminate the vibration on both sides of the placement table.

[0019] 3. The two guide rails in the present invention can not only guide the movement of the stator and the placement table through the slider, but also clamp and limit the position of the two sides of the stator, which can improve the stability of the stator during movement when in use. At the same time, when in use, the staff can selectively install cleaning cotton on the inside of the two ends of the sliding groove. The cleaning cotton can wipe the surface of the position where the guide rail enters the inside of the sliding groove, and the slider is installed in the installation groove on the inner wall of the sliding groove. When in use, it can play a good protective role for the contact position between the slider and the guide rail. When in use, it can prevent external dust from covering the surface of the guide rail. When the slider slides on the outer wall of the guide rail, the dust contacts the connection position of the slider and the guide rail, causing slight vibration of the placement table.

[0020] 4. In the present invention, when the placement table moves, the positioning plate can monitor the vibration of the placement table in real time according to the change of the position of the laser irradiated on its surface. When the placement table vibrates, the vibration of the front and rear positions of the placement table can be eliminated according to the usage situation through the Hall sensor and the electric slider, or the magnetic field strength of the two electromagnet sheets can be adjusted to eliminate the vibration of the two sides of the placement table. The protective shells on both sides of the casing can be connected and fixed to the side covers by fixing bolts. When in use, the two ends of the placement table are located on the top of the protective shell. The placement table can prevent the protective shell from moving up during use, and the limit plate can prevent the protective shell from moving down through the side cover. When in use, the placement table, the protective shell and the side cover cooperate with each other to better fix the position of the protective shell and the side cover.

A support rod is installed on one side of the bottom end of the fixing plate 13 close to the inner wall of the fixing groove 10, and a roller 17 is rotatably installed on the outer wall of the support rod; when in use, the roller 17 can roll on the top of the magnet plate 12 when the placement table 4 moves, which can improve the stability of the placement table 4 when moving when in use.

[0035] As a technical optimization scheme of the present invention, an annular limiting groove 33 is opened on the outer wall of one end of the roller 17 close to the fixed plate 13, and the inner wall of the limiting groove 33 abuts against the top of the magnet plate 12. The bottom of the end of the roller 17 away from the fixed plate 13 is located between the fixed plate 13 and the inner wall of the fixed groove 10, and the roller 17 is located between the electromagnet sheet 32 ​​and the magnet plate 12; when in use, the electromagnet sheet 32 ​​is energized with an external power source, so that the electromagnet sheet 32 ​​generates a magnetic field, and pushes the magnet plate 12 downward through the magnetic field repulsion force.

[0036] As a technical optimization scheme of the present invention, a plurality of springs 14 are installed at the inner bottom of the fixed groove 10 in the length direction, and the top of the spring 14 is installed at the bottom of the magnet plate 12. Guide grooves 29 are opened on the inner walls at both ends of the fixed groove 10, and guide blocks 30 are installed at both ends of the magnet plate 12. The two guide blocks 30 are respectively slidably installed inside the two guide grooves 29; when the magnet plate 12 moves downward, the plurality of springs 14 can push the magnet plate 12 to move upward, so that the roller 17 is more stable when rolling on the top of the magnet plate 12. At the same time, when in use, the staff controls the magnetic field strength of the electromagnet sheet 32 ​​by adjusting the current of the electromagnet sheet 32, and adjusts the height position of the magnet plate 12 by adjusting the magnetic field strength of the electromagnet sheet 32.

[0037] As a technical optimization solution of the present invention, adjustment grooves 24 are opened on the inner walls on both sides of the placement groove 8 in the length direction, electric sliders 25 are installed on both sides of the placement plate 9, and the electric sliders 25 are slidably installed inside the adjustment grooves 24, and positioning plates 16 are installed at both ends of the placement table 4; when the object on the top of the placement plate 9 presses down the top of the Hall sensor 23 through the placement plate 9, the Hall sensor 23 can detect the force at different positions on its top, and adjust the position of the placement plate 9 and the object on its top through the electric slider 25.

[0038] As a technical optimization solution of the present invention, a groove 15 is opened at the inner bottom of the casing 1 in the length direction, and a stator 5 is installed at the inner bottom of the groove 15. The stator 5 is located below the mover 18. Side covers 3 are installed at both ends of the casing 1, and limiting plates 7 are installed on the opposite surfaces of the two side covers 3. The bottom end of the limiting plate 7 abuts against the inner bottom of the groove 15. When in use, the magnetic field of the stator 5 and the magnetic field of the mover 18 cooperate with each other to drive the placement table 4 to move.

[0039] As a technical optimization scheme of the present invention, a laser positioning sensor 26 matching the positioning plate 16 is installed on the top side of the limit plate 7, and bumpers 28 are installed on both ends of the side of the side cover 3. The two bumpers 28 are respectively located on both sides of the limit plate 7, and the bottom ends of the bumpers 28 abut against the inner bottom of the casing 1; when the placement table 4 moves, the laser of the laser positioning sensor 26 is irradiated on the side of the positioning plate 16, and the vibration of the placement table 4 is detected by the change in the position of the laser irradiated on the surface of the positioning plate 16 when the placement table 4 moves.

[0040] As a technical optimization solution of the present invention, sliding grooves 19 are opened on both sides of the mover 18 in the length direction, and installation grooves 20 are opened at both ends of the inner wall of the sliding groove 19. Guide rails 6 are installed on the inner walls of both sides of the casing 1 in the length direction, and the middle end of the guide rail 6 is slidably installed in the sliding groove 19; when in use, the guide rail 6 is slidably installed in the sliding groove 19, so that the guide rail 6 can play a better supporting and moving guiding role on the stator 5 through the sliding groove 19.

[0041] As a technical optimization solution of the present invention, a slider 21 is installed on the inner wall of the mounting groove 20, and one end of the slider 21 away from the inner wall of the mounting groove 20 is slidably installed on the outer wall of the guide rail 6; when the placement table 4 and the stator 5 move, the slider 21 slides on the outer wall of the guide rail 6, thereby improving the stability of the placement table 4 when it moves.

[0042] As a technical optimization solution of the present invention, protective shells 2 are installed on both sides of the casing 1, and screw holes 31 are opened on the side surfaces of both ends of the protective shell 2. One end of the screw hole 31 passes through the end surfaces of the protective shell 2 and the side cover 3, and the internal thread of the screw hole 31 is installed with a fixing bolt 27; when in use, the protective shell 2 can play a good protective role on the magnet plates 12 and several springs 14 on both sides of the casing 1, preventing outsiders from affecting the position of the magnet plates 12.

[0043] When the present invention is in use, the staff places the items to be transported on the top of the placement plate 9 at the bottom of the placement table 4. When in use, the bottom of the placement plate 9 abuts against the top of the Hall sensor 23. After the staff places the items on the top of the placement plate 9, the items can press down the top of the Hall sensor 23 through the placement plate 9. When in use, the Hall sensor 23 can detect the stress conditions at different positions on its top. When the pressures at both ends of the top of the Hall sensor 23 are different, the electric sliders 25 located on both sides of the placement plate 9 can drive the placement plate 9 to move inside the placement groove 8 at the top of the placement table 4, and the placement plate 9 slides on the top of the Hall sensor 23. When the placement plate 9 and the items on its top move, the Hall sensor 23 can detect the stress conditions at different positions on its top in real time until the stress conditions at different positions on the top of the Hall sensor 23 are the same. When in use, the placement position of the items on the top of the placement plate 9 can be adjusted. When the staff needs to place and move irregular objects, it can prevent the placement table 4 from shaking or vibrating slightly due to uneven load when moving, which can improve the stability of the objects when moving.

[0044] When in use, the two guide rails 6 are slidably installed in the sliding grooves 19 on both sides of the stator 5, and the sliders 21 slidably installed on the outer walls of the guide rails 6 are installed in the mounting grooves 20 on the inner walls of the sliding grooves 19. When in use, the two guide rails 6 can not only play a good guiding role in the movement of the stator 5 and the placement table 4 through the sliders 21, but also clamp and limit the positions of the two sides of the stator 5, which can improve the stability of the stator 5 when moving. At the same time, when in use, the staff can selectively install cleaning cotton on the inside of the two ends of the sliding grooves 19. When the stator 5 moves, the cleaning cotton can wipe the surface of the position where the guide rail 6 enters the sliding groove 19, and the slider 21 is installed in the mounting groove 20 on the inner wall of the sliding groove 19, which can play a good protective role in the contact position between the slider 21 and the guide rail 6 when in use, and can prevent external dust from covering the surface of the guide rail 6 when in use, and the placement table 4 will vibrate slightly due to dust when the slider 21 moves on the outer wall of the guide rail 6.

[0045] When the placement table 4 moves, several fixing plates 13 located at both ends of the placement table 4 are slidably installed in the sliding holes 11 on both sides of the top of the casing 1 respectively. The sliding holes 11 can improve the stability of the placement table 4 when moving on both sides through the fixing plates 13. At the same time, the side surfaces of the several fixing plates 13 abut against the inner walls of the sliding holes 11. When in use, the several fixing plates 13 located on both sides of the placement table 4 can clamp and limit the two sides of the casing 1 to prevent the placement table 4 from shaking on both sides when moving.

[0046] When the placing table 4 is moved during use, the rollers 17 located on the sides of the fixed plates 13 on both sides of the placing table 4 roll on the top of the magnet plate 12, and at the same time, the end of the roller 17 away from the fixed plate 13 is located between the magnet plate 12 and the inner wall of the fixed groove 10, and the electromagnet sheet 32 ​​and the magnet plate 12 can better limit the position of the roller 17, and the end of the magnet plate 12 close to the inner wall of the fixed groove 10 abuts against the inner wall of the limit groove 33 on the roller 17, which can make the roller 17 more stable when rolling on the top of the magnet plate 12 during use. When in use, the electromagnet sheet 32 ​​is connected to the external power supply, so that the electromagnet sheet 32 ​​generates a magnetic field, and the magnetic field pushes the magnet plate 12 to move downward through the repulsive force, and the plurality of springs 14 located at the bottom of the fixed groove 10 can push the magnet plate 12 to move upward.

[0047] When in use, the staff can control the magnetic field strength of the electromagnet sheet 32 ​​by the magnitude of the current through which the electromagnet sheet 32 ​​is energized. When the magnetic field strength of the electromagnet sheet 32 ​​is high, the magnet plate 12 can move down and disconnect from the roller 17. When the placement table 4 vibrates on both sides when moving, the staff can reduce the magnetic field strength of the electromagnet sheet 32 ​​by the magnitude of the current, so that the spring 14 pushes the magnet plate 12 to move up, and according to the vibration amplitude on both sides of the placement table 4, the top of the magnet plate 12 and the inner wall of the upper limit groove 33 of the roller 17 are slightly abutted against each other, and the squeezing force between the magnet plate 12 and the inner wall of the limit groove 33 on the roller 17 is adjusted according to the magnitude of the vibration amplitude on both sides of the placement table 4. When both sides of the placement table 4 vibrate, the two magnet plates 12 can support the two sides of the placement table 4 respectively, and make the several rollers 17 on both sides of the placement table 4 roll on the top of the magnet plate 12, so as to eliminate the vibration on both sides of the placement table 4.

[0048] When in use, the laser positioning sensors 26 located on the limit plates 7 on the opposite surfaces of the two side covers 3 are respectively located at the two ends of the placement table 4. When the placement table 4 moves, the lasers emitted by the two laser positioning sensors 26 are respectively irradiated on the surfaces of the positioning plates 16 at the two ends of the placement table 4. When the placement table 4 moves, the positioning plates 16 can monitor the vibration of the placement table 4 when it moves in real time according to the changes in the position of the laser irradiated on its surface. When the placement table 4 vibrates, the vibration of the front and rear positions of the placement table 4 can be eliminated according to the usage situation through the Hall sensor 23 and the electric slider 25, or the vibration of the two side positions of the placement table 4 can be eliminated by adjusting the magnetic field strength of the two electromagnet sheets 32.

[0049] When in use, the bottom end of the limit plate 7 abuts against the inner bottom of the groove 15, which can play a good role in limiting the installation position of the side cover 3, so that the laser emitted by the laser positioning sensor 26 on the side of the limit plate 7 can accurately irradiate the surface of the positioning plate 16. At the same time, when in use, the protective shell 2 located on both sides of the casing 1 can be connected and fixed to the side cover 3 by fixing bolts 27. When in use, the two ends of the placement table 4 are located on the top of the protective shell 2. The placement table 4 can prevent the protective shell 2 from moving up during use, and the limit plate 7 can prevent the protective shell 2 from moving down through the side cover 3. When in use, the placement table 4, the protective shell 2 and the side cover 3 cooperate with each other, which can better fix the position of the protective shell 2 and the side cover 3.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
