Description

Technical Field

[0001] This invention relates to the field of stepper module motor technology, specifically a small-volume, high-precision linear motion stepper module motor. Background Technology

[0002] A linear motion stepper module motor is a device that combines a stepper motor with a linear motion module, primarily used for precise linear motion control. The stepper motor receives electrical pulse signals to achieve precise angle or length control, while the linear motion module converts this rotational motion into linear motion. The stepper motor module can then achieve high-precision positioning and speed control by controlling the frequency and phase of the current. Therefore, it is widely used in automation equipment, CNC machine tools, robotics, and other fields. Currently, stepper motor modules are available in two types: open and closed. Closed structures are suitable for dusty environments; however, fully enclosed structures make it difficult to locate faults after they occur internally, making repairs more complicated. Therefore, open-structure motor modules are more commonly used in general working environments.

[0003] Existing small-volume, high-precision linear motion stepper module motors inevitably accumulate dust during use due to the exposed lead screw drive structure. When dust accumulates on the lead screw, it increases friction between components, leading to unstable movement, which in turn affects the movement accuracy and generates vibration and noise. Summary of the Invention

[0004] The purpose of this invention is to provide a small-volume, high-precision linear motion stepper module motor to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The small-volume, high-precision linear motion stepper module motor includes a groove, in which a ball screw is rotatably mounted, and a stepper motor is mounted at one end of the groove. The output shaft of the stepper motor is connected to one end of the ball screw. A driver is mounted on the stepper motor. A slide block is slidably mounted on the ball screw, and a slide table is mounted on the slide block. A first displacement sensor and a second displacement sensor are respectively mounted at the two ends of the groove near the ball screw. Guide rails are symmetrically mounted on both sides of the bottom of the slide table, and two sliders are symmetrically slidably mounted on the guide rails. A transmission rod is mounted at the bottom of the sliders, and a semi-circular plate is mounted at the bottom of the transmission rod. A wiping device is mounted on the semi-circular plate. The pad, the guide rail is electrically connected to the first displacement sensor and the second displacement sensor. The driver receives pulse signals to control the stepper motor, so that the ball screw can drive the slide on the slide block to move linearly. At the same time, the first displacement sensor and the second displacement sensor can detect the moving slide block. When the slide block becomes unstable during movement, the first displacement sensor and the second displacement sensor can control the guide rail to move, so that the two sliders on the same side drive the two semi-ring plates to engage in opposite directions through the transmission rod. This allows the wiping pad to radially cover the ball screw, which is beneficial for the wiping pad to wipe and clean the ball screw as the slide block moves, achieving the effect of dust removal, and thus ensuring the moving accuracy of the slide block.

[0006] As a preferred technical solution, the two semi-ring plates on the same side are joined together to form a ring, and the ring is concentric with the ball screw.

[0007] As a preferred technical solution, the tank is provided with a primary cleaning component and a secondary cleaning component, and the operation of the primary cleaning component provides the driving force for the operation of the secondary cleaning component.

[0008] As a preferred technical solution, the primary cleaning assembly includes a drive shaft, a turntable, a fixed rod, an end plate, a rotating column, an electric push rod, a mounting plate, and drive teeth;

[0009] A drive shaft is rotatably mounted on the end of the groove away from the stepper motor. One end of the drive shaft is connected to a ball screw, and the other end is mounted on a turntable. A fixed rod is mounted on the end of the groove near the turntable, and an end plate is mounted on the fixed rod. A rotating column is rotatably mounted on the end plate. An electric push rod is mounted on the end of the rotating column near the turntable, and a plate is mounted on the end of the electric push rod. A drive tooth is mounted on the other end of the rotating column. The electric push rod is electrically connected to a guide rail. When the guide rail is running, it can control the electric push rod to move, causing the electric push rod to extend and fit the plate against the center of the turntable. Utilizing the frictional force between the plate and the turntable, the ball screw can drive the electric push rod to rotate synchronously through the drive shaft and the turntable. During rotation, the electric push rod can drive the drive tooth to rotate synchronously through the rotating column.

[0010] As a preferred technical solution, the primary cleaning assembly includes a fixed plate, a rotating shaft, a first reciprocating screw, a connecting shaft, a driven gear, a transmission chain, a moving block, a transmission ring gear, a cleaning roller, a toothed plate, and a passageway hole.

[0011] Two fixed plates are symmetrically installed on the lower part of one side of the tank. A rotating shaft is rotatably mounted on each of the two fixed plates. The two rotating shafts are connected by a first reciprocating screw. A connecting shaft is installed at the end of the rotating shaft near the drive gear. A driven gear is mounted on the connecting shaft. A transmission chain is fitted onto the driven gear and the drive gear. A moving block is slidably mounted on the first reciprocating screw. A transmission ring gear is rotatably arranged on the side of the moving block near the tank. A cleaning roller is installed at the end of the transmission ring gear away from the moving block. A passage hole is opened at the lower part of the tank near the fixed plate. The cleaning roller passes through the passage hole and is wrapped with a cleaning pad. The cleaning pad is flush with the inner surface of the tank. The bottom contacts the fixed plate, which is equipped with a toothed plate. The toothed plate meshes with the upper part of the transmission ring teeth. When the drive teeth rotate, the toothed chain consisting of the drive teeth, driven teeth, and transmission chain drives the driven teeth to rotate the first reciprocating screw through the connecting shaft. During the rotation of the first reciprocating screw, the moving block moves laterally back and forth. During the reciprocating movement, the moving block drives the cleaning roller to clean the bottom of the tank. At the same time, during the movement of the moving block, the meshing action between the transmission ring teeth and the toothed plate allows the transmission ring teeth to drive the cleaning roller to rotate in the direction of movement, thereby improving the cleaning effect of the cleaning pad on the cleaning roller.

[0012] As a preferred technical solution, the moving block is provided with a first chamber, and a rotating tube is rotatably installed on the side of the first chamber near the tank. An electrode post is installed at the end of the rotating tube in the first chamber, and multiple cutting plates are circumferentially arranged on the electrode post. Two magnetic blocks are symmetrically installed in the first chamber, namely a positive magnetic block and a negative magnetic block. A transmission ring tooth is installed at the other end of the rotating tube. The cleaning roller is provided with a second chamber, and a conductive layer is installed in the second chamber. The conductive layer is connected to the electrode post through a wire. When the cleaning roller rotates, the cleaning roller can drive the cutting plate on the electrode post to rotate through the rotating tube, so that the cutting plate cuts the magnetic field lines between the two magnetic blocks during the rotation, forming a current. Then, the electrode post can conduct electricity to the conductive layer through the wire, so that the conductive layer generates static electricity on the cleaning pad wrapped on the surface of the cleaning roller, and the cleaning pad forms an electrostatic adsorption of dust, which can improve the cleaning effect of the cleaning pad on the dust at the bottom of the tank.

[0013] As a preferred technical solution, the multi-stage cleaning assembly includes a linkage rod, a squeezing plate, a base plate, a telescopic airbag, a rotating rod, an air disc, a nozzle, a rotary joint, an air pipe, an electric control valve, a second reciprocating screw, a drive block, and a dust pushing pad.

[0014] A linkage rod is installed on the movable block, and an extrusion plate is installed on the linkage rod. Base plates are symmetrically installed on both sides of the bottom of the tank, and both base plates are connected to the extrusion plate via telescopic airbags. Rotating rods are symmetrically and rotatably installed on both sides of the inner wall of the tank away from the passageway hole. An air disc is installed at the end of the rotating rod away from the passageway hole, and multiple nozzles are obliquely installed on the air disc in a circular arrangement. A rotary joint is installed on the input end of the air disc, and the rotary joint is connected to the telescopic airbag on the same side via an air pipe. An electrically controlled valve is installed on the air pipe. A second reciprocating screw is installed on the other end of the rotating rod, and a sliding device is installed on the second reciprocating screw. The device includes a drive block with a dust-pushing pad installed at its bottom. The dust-pushing pad contacts the inner bottom of the tank. When the drive block moves, it can drive the extrusion plate to compress the telescopic airbag in the moving direction via a linkage rod, and stretch the telescopic airbag in the opposite direction to draw in air. The compressed telescopic airbag can then deliver airflow to the air plate through an air pipe. The force of the airflow from the nozzle drives the air plate to rotate, which in turn drives the second reciprocating screw to rotate synchronously via a rotating rod. This allows the drive block to reciprocate along the second reciprocating screw, which helps the drive block to push out the dust accumulated on both sides of the tank, thus achieving dust removal from the tank.

[0015] As a preferred technical solution, a one-way air intake valve is installed on the telescopic airbag, and a rotation sensor is installed on the cleaning roller. The rotation sensor is electrically connected to two electronically controlled valves. By monitoring the rotation direction of the cleaning roller through a rotational actuator, the electronically controlled valves in the corresponding movement direction can be controlled to open.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] When the slide becomes unstable during movement, the first and second displacement sensors can control the guide rail to run, causing the two sliders on the same side to drive the two semi-ring plates to engage in opposite directions via the transmission rod. This allows the wiping pad to radially cover the ball screw, which helps the wiping pad to wipe and clean the ball screw as the slide moves, achieving a dust removal effect and thus ensuring the movement accuracy of the slide.

[0018] This application, through the setting of the primary cleaning component, can utilize the rotation of the ball screw to achieve reciprocating cleaning of the inner bottom of the tank by the cleaning roller. At the same time, it can also drive the cleaning roller to rotate in the moving direction and form electrostatic adsorption, thereby improving the cleaning effect of the cleaning pad on the cleaning roller.

[0019] This application, through the setting of the multi-stage cleaning component, can utilize the movement of the moving block to drive the second reciprocating screw in the moving direction to rotate, which is beneficial for the driving block to drive the dust pushing pad to push out the dust accumulated on both sides inside the tank, thereby realizing the ash removal inside the tank.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example: Figures 1-5As shown, this invention provides a technical solution for a small-volume, high-precision linear motion stepper module motor. This small-volume, high-precision linear motion stepper module motor includes a groove 1, within which a ball screw 2 is rotatably mounted. A stepper motor 3 is mounted at one end of the groove 1, and the output shaft of the stepper motor 3 is connected to one end of the ball screw 2. A driver 4 is mounted on the stepper motor 3. A slide block 5 is slidably mounted on the ball screw 2, and a slide table 6 is mounted on the slide block 5. A first displacement sensor 7 and a second displacement sensor 8 are respectively mounted at the two ends of the groove 1 near the ball screw 2. Guide rails 9 are symmetrically mounted on both sides of the bottom of the slide table 6, and two sliders 10 are symmetrically slidably mounted on the guide rails 9. A transmission rod 11 is mounted at the bottom of the sliders 10, and a semi-circular plate 12 is mounted at the bottom of the transmission rod 11. A wiping pad 13 is mounted on the semi-circular plate 12. The guide rail 9 is electrically connected to the first displacement sensor 7 and the second displacement sensor 8. The driver 4 receives pulse signals to control the stepper motor 3, so that the ball screw 2 can drive the slide table 6 on the slide block 5 to move linearly. At the same time, the first displacement sensor 7 and the second displacement sensor 8 can detect the moving slide block 5. When the slide block 5 becomes unstable during movement, the first displacement sensor 7 and the second displacement sensor 8 can control the guide rail 9 to move, so that the two sliders 10 on the same side drive the two semi-ring plates 12 to engage with each other through the transmission rod 11. This allows the wiping pad 13 to radially cover the ball screw 2, which is beneficial for the wiping pad 13 to wipe and clean the ball screw 2 as the slide block 5 moves, achieving the effect of dust removal and thus ensuring the moving accuracy of the slide block 5.

[0034] Two semi-circular plates 12 on the same side are joined together to form a ring, and the ring is concentric with the ball screw 2.

[0035] The tank 1 is equipped with a primary cleaning component 14 and a secondary cleaning component 15. The operation of the primary cleaning component 14 provides the driving force for the operation of the secondary cleaning component 15.

[0036] like Figures 1-9 As shown, the primary cleaning assembly 14 includes a drive shaft 1401, a turntable 1402, a fixed rod 1403, an end plate 1404, a rotating column 1405, an electric push rod 1406, a mounting plate 1407, and a drive gear 1408.

[0037] A drive shaft 1401 is rotatably mounted on the end of the tank body 1 away from the stepper motor 3. One end of the drive shaft 1401 is connected to the ball screw 2, and the other end is mounted on a turntable 1402. A fixing rod 1403 is mounted on the end of the tank body 1 near the turntable 1402. An end plate 1404 is mounted on the fixing rod 1403, and a rotating column 1405 is rotatably mounted on the end plate 1404. An electric push rod 1406 is mounted on the end of the rotating column 1405 near the turntable 1402, and a plate 1407 is mounted on the end of the electric push rod 1406. A drive gear 140 is mounted on the other end of the rotating column 1405. 8. The electric push rod 1406 is electrically connected to the guide rail 9. When the guide rail 9 is running, the guide rail 9 can control the electric push rod 1406 to run, so that the electric push rod 1406 drives the plate 1407 to extend and fit against the center of the turntable 1402. By utilizing the frictional force between the plate 1407 and the turntable 1402, the ball screw 2 can drive the electric push rod 1406 to rotate synchronously through the transmission shaft 1401 and the turntable 1402 during the rotation process. During the rotation process, the electric push rod 1406 can drive the drive gear 1408 to rotate synchronously through the rotating column 1405.

[0038] The primary cleaning assembly 14 includes a fixed plate 1409, a rotating shaft 1410, a first reciprocating lead screw 1411, a connecting shaft 1412, a driven gear 1413, a transmission chain 1414, a moving block 1415, a transmission ring gear 1416, a cleaning roller 1417, a toothed plate 1418, and a passage hole 1419.

[0039] Two fixed plates 1409 are symmetrically installed on the lower part of one side of the tank body 1. A rotating shaft 1410 is rotatably mounted on each of the two fixed plates 1409. The two rotating shafts 1410 are connected by a first reciprocating lead screw 1411. A connecting shaft 1412 is installed at the end of the rotating shaft 1410 near the drive gear 1408. A driven gear 1413 is installed on the connecting shaft 1412. A transmission chain 1414 is fitted between the driven gear 1413 and the drive gear 1408. The first reciprocating lead screw... A movable block 1415 is slidably mounted on the lead screw 1411. A transmission ring gear 1416 is rotatably mounted on the side of the movable block 1415 near the tank body 1. A cleaning roller 1417 is mounted on the end of the transmission ring gear 1416 away from the movable block 1415. A passage hole 1419 is opened at the lower part of the side of the tank body 1 near the fixed plate 1409. The cleaning roller 1417 passes through the passage hole 1419, and a cleaning pad is wrapped on the cleaning roller 1417. The cleaning pad is flush with the inner bottom of the tank body 1. The toothed plate 1418 is mounted on the fixed plate 1409 and meshes with the upper part of the transmission ring tooth 1416. When the drive tooth 1408 rotates, the tooth chain transmission composed of the drive tooth 1408, driven tooth 1413 and transmission chain 1414 can drive the driven tooth 1413 to rotate through the connecting shaft 1412. During the rotation of the first reciprocating screw 1411, the first reciprocating screw 1411 drives the moving block 1415 to move laterally and reciprocally. During the reciprocating movement, the moving block 1415 drives the cleaning roller 1417 to clean the inner bottom of the tank 1. At the same time, during the movement of the moving block 1415, through the meshing of the transmission ring tooth 1416 and the toothed plate 1418, the transmission ring tooth 1416 can drive the cleaning roller 1417 to always rotate in the moving direction, thereby improving the cleaning effect of the cleaning pad on the cleaning roller 1417.

[0040] The moving block 1415 has a first chamber 1420. A rotating tube 1421 is rotatably mounted on the side of the first chamber 1420 near the tank 1. A pole post 1422 is mounted at the end of the rotating tube 1421 of the first chamber 1420. Multiple cutting plates 1423 are circumferentially arrayed on the pole post 1422. Two magnetic blocks 1424 are symmetrically mounted in the first chamber 1420, which are a positive magnetic block and a negative magnetic block, respectively. A transmission ring gear 1416 is mounted at the other end of the rotating tube 1421. The cleaning roller 1417 has a second chamber 1425. A conductive layer 1426 is installed in the second chamber 1425. The conductive layer 1426 is connected to the pole post 1422 through a wire 1427. When the cleaning roller 1417 enters the tank, the conductive layer 1426 is connected to the pole post 1422. When the roller rotates, the cleaning roller 1417 can drive the cutting plate 1423 on the pole post 1422 to rotate through the rotating tube 1421. This allows the cutting plate 1423 to cut the magnetic field lines between the two magnetic blocks 1424 during rotation, forming a current. This allows the pole post 1422 to conduct electricity to the conductive layer 1426 through the wire 1427, causing the conductive layer 1426 to generate static electricity on the cleaning pad wrapped on the surface of the cleaning roller 1417. This causes the cleaning pad to electrostatically attract dust, which can improve the cleaning effect of the cleaning pad on the dust at the bottom of the tank 1. Furthermore, by taking advantage of the turning interval when the cleaning roller 1417 moves to the inside of the tank 1, the dust attracted on the cleaning pad can fall off and accumulate on the inside of the tank 1.

[0041] like Figures 1-5 , Figure 7 and Figure 9 As shown, the multi-stage cleaning assembly 15 includes a linkage rod 1501, a pressing plate 1502, a base plate 1503, a telescopic airbag 1504, a rotating rod 1505, an air disc 1506, a nozzle 1507, a rotary joint 1508, an air pipe 1509, an electric control valve 1510, a second reciprocating screw 1511, a drive block 1512, and a dust pushing pad 1513;

[0042] A linkage rod 1501 is installed on the movable block 1415, and an extrusion plate 1502 is installed on the linkage rod 1501. Base plates 1503 are symmetrically installed on both sides of the bottom of the tank 1. Both base plates 1503 are connected to the extrusion plate 1502 via telescopic airbags 1504. Rotating rods 1505 are symmetrically and rotatably installed on both sides of the inner wall of the tank 1 away from the passage hole 1419. An air disc 1506 is installed at the end of the rotating rod 1505 away from the passage hole 1419. Multiple nozzles 1507 are obliquely mounted on the air disc 1506, arranged in a circular array. A rotary joint 1508 is mounted on the input end of the air disc 1506, and the rotary joint 1508 is connected to the telescopic airbag 1504 on the same side via an air pipe 1509. An electric control valve 1510 is mounted on the air pipe 1509. A second reciprocating screw 1511 is mounted on the other end of the rotating rod 1505, and a drive mechanism is slidably mounted on the second reciprocating screw 1511. The bottom of the drive block 1512 is equipped with a dust-pushing pad 1513, which is in contact with the inner bottom of the tank 1. When the moving block 1415 moves, the moving block 1415 can drive the extrusion plate 1502 to compress the telescopic airbag 1504 in the moving direction through the linkage rod 1501, and stretch the telescopic airbag 1504 in the opposite direction to suck in air. The compressed telescopic airbag 1504 can deliver airflow to the air plate 1506 through the air pipe 1509. The airflow force of the nozzle 1507 drives the air plate 1506 to rotate, so that the air plate 1506 drives the second reciprocating screw 1511 to rotate synchronously through the rotating rod 1505, so that the drive block 1512 can move back and forth along the second reciprocating screw 1511. This is beneficial for the drive block 1512 to drive the dust-pushing pad 1513 to push out the dust accumulated on both sides of the inside of the tank 1, thereby realizing the dust discharge in the tank 1.

[0043] A one-way air intake valve is installed on the telescopic airbag 1504, and a rotation sensor is installed on the cleaning roller 1417. The rotation sensor is electrically connected to two electrically controlled valves 1510.

[0044] Working principle of the invention:

[0045] The driver 4 receives pulse signals to control the stepper motor 3, enabling the ball screw 2 to drive the slide table 6 on the slide block 5 to move linearly. At the same time, the first displacement sensor 7 and the second displacement sensor 8 can detect the movement of the slide block 5. When the slide block 5 becomes unstable during movement, the first displacement sensor 7 and the second displacement sensor 8 can control the guide rail 9 to move, so that the two sliders 10 on the same side drive the two semi-ring plates 12 to engage with each other through the transmission rod 11. This allows the wiping pad 13 to radially cover the ball screw 2, which is beneficial for the wiping pad 13 to wipe and clean the ball screw 2 as the slide block 5 moves, achieving the effect of dust removal and thus ensuring the movement accuracy of the slide block 5.

[0046] When the guide rail 9 is running, it controls the operation of the electric push rod 1406, causing the electric push rod 1406 to extend and adhere to the center of the turntable 1402. Utilizing the friction between the plate 1407 and the turntable 1402, the ball screw 2 can drive the electric push rod 1406 to rotate synchronously via the transmission shaft 1401 and the turntable 1402. During rotation, the electric push rod 1406 can drive the drive gear 1408 to rotate synchronously via the rotating column 1405. When the drive gear 1408 rotates, the drive gear 1408, the driven gear 1413, and the transmission chain 1414 form a [mechanical system / mechanical structure]. The gear chain drive allows the driven tooth 1413 to drive the first reciprocating screw 1411 to rotate via the connecting shaft 1412. During the rotation of the first reciprocating screw 1411, the moving block 1415 is driven to move laterally and reciprocally. This allows the moving block 1415 to drive the cleaning roller 1417 to clean the inner bottom of the tank 1 during the reciprocating movement. At the same time, during the movement of the moving block 1415, the meshing action of the transmission ring tooth 1416 and the toothed plate 1418 allows the transmission ring tooth 1416 to drive the cleaning roller 1417 to rotate in the direction of movement, thereby improving the cleaning effect of the cleaning pad on the cleaning roller 1417.

[0047] When the cleaning roller 1417 rotates, it can drive the cutting plate 1423 on the pole post 1422 to rotate through the rotating tube 1421. This allows the cutting plate 1423 to cut the magnetic lines of force between the two magnetic blocks 1424 during rotation, forming a current. This allows the pole post 1422 to conduct electricity to the conductive layer 1426 through the wire 1427, causing the conductive layer 1426 to generate static electricity on the cleaning pad wrapped on the surface of the cleaning roller 1417. This causes the cleaning pad to electrostatically attract dust, which can improve the cleaning effect of the cleaning pad on the dust at the bottom of the tank 1. Furthermore, by taking advantage of the turning interval when the cleaning roller 1417 moves to the inside of the tank 1, the dust attracted on the cleaning pad can fall off and accumulate on the inside of the tank 1.

[0048] When the moving block 1415 moves, it can drive the extrusion plate 1502 to compress the telescopic airbag 1504 in the moving direction via the linkage rod 1501, and stretch the telescopic airbag 1504 in the opposite direction to draw in air. The compressed telescopic airbag 1504 can deliver airflow to the air plate 1506 through the air pipe 1509. The airflow force of the nozzle 1507 drives the air plate 1506 to rotate, so that the air plate 1506 drives the second reciprocating screw 1511 to rotate synchronously via the rotating rod 1505, so that the drive block 1512 can move back and forth along the second reciprocating screw 1511.
