Description

Technical Field

[0001] The present invention relates to the technical field of stator assembly, and particularly to a dust removal device for a motor stator and a tooling fixture. Background Art

[0002] The stator is the stationary part of a motor or a generator, and mainly consists of a stator core and coils wound around the stator core. During the assembly process of the stator, due to the exposed environment, the stator and its positioning tooling fixture will carry dust and generate static electricity. The static electricity will cause the dust to adhere to the stator and the tooling fixture. If not removed, the dust will accumulate, which will have an adverse effect on the assembly of the stator. In severe cases, it may even cause the motor to be scrapped, resulting in unnecessary losses. Therefore, a dust removal device for a motor stator is needed, which can remove dust cleanly and thoroughly. Summary of the Invention

[0003] The present invention aims to provide a dust removal device for a motor stator and a tooling fixture to overcome the deficiencies in the prior art.

[0004] To solve the above technical problems, the technical solution of the present invention is: A dust removal device for a motor stator and a tooling fixture, comprising a frame, a transmission mechanism, a clamping mechanism, a dust removal mechanism and a dust suction mechanism. On one side inside the frame, there is a transmission mechanism for transmitting the stator and the stator tooling fixture. The transmission mechanism includes a transmission line body and a lifting mechanism arranged inside the transmission line body. On one side of the transmission mechanism, there is a workbench, on which there is a clamping mechanism. Above the clamping mechanism, there is a dust removal mechanism, and below it, there is a dust suction mechanism. The dust removal mechanism includes an upper cover, a first lifting mechanism for driving the upper cover to lift, a blowing and cleaning mechanism and an electrostatic dust removal mechanism. Both the blowing and cleaning mechanism and the electrostatic dust removal mechanism are connected to an external air source through air ducts. The external air source includes a compressor and a dryer connected in sequence, which stores and dries the external air and then blows and cleans the dust, which can increase the cleaning strength while reducing the damage to the stator. The dust suction mechanism includes a lower cover and a second lifting mechanism for driving the lower cover to lift. The lower cover is slidably connected to the workbench through the second lifting mechanism. During dust removal, the upper cover and the lower cover are closed to form a closed dust removal chamber. The lower cover is a conical structure with a larger upper part and a smaller lower part, and a dust suction air duct is connected to its bottom. The conical structure of the lower cover has a good dust suction effect, and the dust suction air duct is connected to a vacuum cleaner.

[0005] Further, in the above dust removal device for a motor stator and a tooling fixture, the clamping mechanism includes a transverse movement mechanism and a clamping jaw mechanism arranged on the transverse movement mechanism. Buffer and limit components are provided on both the transverse movement mechanism and the clamping jaw mechanism. By means of the buffer and limit components, the strokes of the slide cylinder and the clamping jaw cylinder are restricted, so as to achieve precise positioning and eliminate the noise generated by collisions.

[0006] Further, for the dust removal device of the above-mentioned motor stator and tooling, the transverse movement mechanism includes a bottom plate, a slide table cylinder, a first slide rail, and a transverse movement plate. The bottom plate is fixed on the workbench. The slide table cylinder and the slide rail are both fixed on the bottom plate. The transverse movement plate is connected to the slide plate of the slide table cylinder and the first slide rail. The first slide rail makes the movement of the transverse movement plate more stable and smooth. An avoidance hole is provided on the bottom plate for the lower cover to pass through and communicate with the workbench.

[0007] Further, for the dust removal device of the above-mentioned motor stator and tooling, the jaw mechanism includes a second slide rail, a jaw cylinder, and jaws. Two oppositely arranged jaw cylinders are provided on one side of the transverse movement plate, and two second slide rails arranged parallel to the jaw cylinders are provided on the other side. The output ends of the jaw cylinders are respectively connected to the ends of one jaw. The end of the jaw away from the jaw cylinder is connected to the slider on the second slide rail. The setting of the second slide rail makes the movement of the transverse movement plate more stable and smooth. When clamping, the two jaw cylinders extend simultaneously, and the two jaws move towards each other. The jaws can cooperate with the stator tooling to clamp the tooling. Conversely, the jaws release the stator tooling.

[0008] Further, for the dust removal device of the above-mentioned motor stator and tooling, the first lifting mechanism includes a column, a top plate, a first lifting cylinder, and a lifting plate. Columns are provided at the four corners of the workbench. The top of the column is connected to the top plate. The first lifting cylinder is fixed above the top plate. The output end of the first lifting cylinder is connected to a connecting seat through a floating joint. A fixing plate is connected below the connecting seat. Guide columns are provided at the four corners of the fixing plate. The other ends of the guide columns are connected to the lifting plate. Linear bearings are provided at the four corners of the lifting plate and are slidably connected to the columns through the linear bearings. The upper end of the upper cover is fixed on the fixing plate, and the lower end is sleeved in the limiting hole in the center of the lifting plate. The limiting hole can prevent the lower end of the upper cover from shaking during movement and is conducive to the cooperation between the upper cover and the lower cover.

[0009] Further, for the dust removal device of the above-mentioned motor stator and tooling, the air blowing and cleaning mechanism is arranged on the fixing plate and includes an air blowing column and a rotary joint. The upper end of the air blowing column is a connecting pipe, and the lower end is an air blowing column body. The air blowing column body is located inside the upper cover, and multiple air blowing holes are provided on both sides in the vertical direction. The top of the connecting pipe is connected to the rotary joint. The rotary joint is connected to an external air source and is connected to the fixing plate through a joint connecting seat. When the air blowing column rotates and blows air, the connecting pipe of the external air source connected to the rotary joint will not rotate along with it. The connecting pipe is also rotatably connected to the fixing plate through a rotating mechanism.

[0010] Furthermore, the dust removal device of the above-mentioned motor stator and tooling, the rotating mechanism includes a servo motor and a bearing fixing plate, a bearing fixing plate connected by a connecting column is provided below the fixing plate, and bearing seats are provided at both ends of the connecting tube, one end of the bearing seat is connected to the fixing plate, and the other end of the bearing seat is connected to the bearing fixing plate, and the connecting tube is also provided with a synchronous wheel arranged between the two bearing seats, and the servo motor is arranged above the fixing plate and drives the connecting tube to rotate through a synchronous belt transmission. Rotating the blowing column by the rotating mechanism can increase the blowing area and improve the dust removal effect. When the lifting cylinder is extended, it drives the connecting seat to descend, and the connecting seat drives the fixing plate fixed to it to descend. The descent of the fixed plate drives the lifting plate to slide along the column and drives the upper cover, the blowing column and the ion wind nozzle to move downward. When the lifting mechanism stops, the lower end of the blowing column extends into the inner hole of the stator, and some of the blowing holes are located above the stator, which is conducive to cleaning the inside and top of the stator.

[0011] Furthermore, the dust removal device for the motor stator and tooling described above includes an electrostatic dust removal mechanism comprising an ion generator and an ion air nozzle. The ion generator is fixed above the top plate. Multiple ion air nozzles are provided and connected to the ion generator via an ion air duct, which extends through the drag chain and through holes in the fixed plate to the bottom of the fixed plate. The ion air nozzles are located around the bearing fixed plate, and the bearing fixed plate has multiple mounting holes on the side of the plate. The ion air nozzles can be adjustably mounted on the bearing fixed plate through the mounting holes. This ion air nozzle is easy to install and has a good cleaning effect.

[0012] Furthermore, the dust removal device for the motor stator and tooling described above comprises a second lifting mechanism comprising a second lifting cylinder and a lower cover connecting plate. The workbench is provided with two symmetrically arranged lifting cylinders, each with symmetrically arranged guide rods on either side. The output end of the second lifting cylinder is provided with a guide rod connecting plate. The upper end of the guide rod is connected to the guide rod connecting plate, and the lower end passes through the workbench and is connected to the lower cover connecting plate. The outer side of the guide rod is provided with a linear bearing fixed to the workbench, and the lower cover is fixed to the lower cover connecting plate. During dust removal, the second lifting cylinder extends, driving the guide rod upward, thereby driving the lower cover connecting plate and the lower cover upward, cooperating with the downwardly moving upper cover to form a dust removal chamber.

[0013] Furthermore, the dust removal device for the motor stator and tooling described above includes a vacuum cleaner comprising an air suction pump and a dust collection box connected in sequence along the suction direction. Exhaust gas containing dust within the dust removal chamber is sucked away by the air suction pump through the lower hood and dust collection duct. The dust collection box collects and processes the dust in the exhaust gas, and the remaining air is discharged into the air, thereby reducing environmental pollution.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The combination of electrostatic dust removal and blowing dust removal is adopted to clean the dust on the stator and the stator tooling. After cleaning the dust, a dust suction mechanism is used to suck away the dust in the dust removal cavity for subsequent collection and treatment, avoiding the re-adhesion of dust on the tooling and reducing environmental pollution; the degree of automation is high, the cleaning is clean and thorough, and the cleaning effect is good, which is beneficial to the assembly of the stator and the motor.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] As Figures 1-9As shown in the figure, a dust removal device for a motor stator and a tooling includes a frame 1, a transmission mechanism 2, a clamping mechanism 3, a dust removal mechanism 4 and a dust suction mechanism 5. On one side inside the frame 1, there is a transmission mechanism 2 for transmitting the stator and the stator tooling 6. On one side of the transmission mechanism 2, there is a workbench 7. On the workbench 7, there is a clamping mechanism 3. Above the clamping mechanism 3, there is a dust removal mechanism 4, and below it, there is a dust suction mechanism 5. The dust removal mechanism 4 includes an upper cover 41, a lifting mechanism 42 for driving the upper cover 41 to lift, a blowing and cleaning mechanism 43 and an electrostatic dust removal mechanism 44. Both the blowing and cleaning mechanism 43 and the electrostatic dust removal mechanism 44 are connected to an external air source through air ducts. The external air source includes a compressor 45 and a dryer 46 connected in sequence. The outside air is pressurized and dried before being used for dust blowing and cleaning, which can increase the cleaning strength while reducing damage to the stator. The dust suction mechanism 5 includes a lower cover 51 and a lifting mechanism 52 for driving the lower cover 51 to lift. The lower cover 51 is slidably connected to the workbench 7 through the lifting mechanism 52. During dust removal, the upper cover 41 and the lower cover 51 are closed to form a closed dust removal chamber. The lower cover 51 is a conical structure with a larger upper part and a smaller lower part, and its bottom is connected to a dust suction air duct 53. The conical structure of the lower cover has a good dust suction effect. The dust suction air duct 53 is connected to a dust collector 54. The dust collector 54 includes an air suction pump 541 and a dust collection box 542 connected in sequence along the air suction direction. The waste gas containing dust in the dust removal chamber is sucked away by the air suction pump 541 through the lower cover 51 and the dust suction air duct 53. The dust collection box 542 collects and processes the dust in the waste gas, and the remaining air is discharged into the air, which can reduce environmental pollution.

[0035] The principle of the weighing device for detecting the number of phases of the stator in the present invention is as follows: The transmission mechanism 2 includes a transmission line body and a lifting mechanism arranged inside the transmission line body. The stator tooling 6 is transported to the cleaning station inside the frame 1 through the transmission line body. After being sensed by an induction switch and blocked by a stopper for positioning, the lifting mechanism raises the stator tooling 6. The clamping mechanism 3 clamps the stator tooling 6 to the detection station. Then, the lifting mechanism 42 and the lifting mechanism 52 are started, and the upper cover 41 and the lower cover 51 approach each other to enclose the stator tooling 6 on the clamping mechanism 3 in the dust removal chamber. The blowing and cleaning mechanism 43 and the electrostatic dust removal mechanism 44 are started to clean the dust and static electricity on the stator and the stator tooling 6. The combination of electrostatic dust removal and blowing dust removal can clean the dust on the stator and the stator tooling completely. Then, the dust suction mechanism 5 is started to suck the dust in the dust removal chamber into the dust collector 54 for subsequent processing, and the dust in the dust removal chamber is cleaned to prevent the dust from adhering to the tooling again. After cleaning, the upper cover 41 and the lower cover 51 are opened, and the clamping mechanism 3 clamps the tooling to the transmission line body. The transmission line body starts to transport the stator tooling 6 to the next station, and so on in a cycle to start the cleaning of the next stator and stator tooling. This dust removal device for the motor stator has a high degree of automation, is cleaned cleanly and thoroughly, has a good cleaning effect, and is beneficial to the assembly of the stator and the motor.

Buffer limiting components 33 are provided on both the transverse movement mechanism 31 and the jaw mechanism 32. By means of the buffer limiting components 33, the strokes of the slide cylinder 312 and the jaw cylinder 322 are restricted, achieving precise positioning and eliminating the noise generated by collisions.

[0038] Among them, the transverse movement mechanism 31 includes a bottom plate 311, a slide cylinder 312, a first slide rail 313, and a transverse movement plate 314. The bottom plate 311 is fixed on the workbench 7. The slide cylinder 312 and the slide rail 313 are both fixed on the bottom plate 311. A transverse movement plate 314 is connected to the slide plate of the slide cylinder 312 and the first slide rail 313. The first slide rail 313 makes the movement of the transverse movement plate 314 more stable and smooth. An avoidance hole through which the lower cover 51 communicates with the workbench 7 is provided on the bottom plate 311.

[0039] Among them, the jaw mechanism 32 includes a second slide rail 321, a jaw cylinder 322, and jaws 323. Two oppositely arranged jaw cylinders 322 are provided on one side of the transverse movement plate 314, and two second slide rails 323 arranged parallel to the jaw cylinders 322 are provided on the other side. The output ends of the jaw cylinders 322 are respectively connected to the ends of one jaw 323. The end of the jaw 323 far from the jaw cylinder 322 is connected to the slider on the second slide rail 321. The setting of the second slide rail 321 makes the movement of the jaw 323 more stable and smooth. When clamping, the two jaw cylinders 322 extend simultaneously, and the two jaws 323 move towards each other. The jaws 323 cooperate with the stator tooling 6 to clamp the tooling. Conversely, the jaws 323 release the stator tooling 6.

[0040] Embodiment 3

[0041] Based on the structure of Embodiment 2, as Figures 6-9As shown, the lifting mechanism 42 includes a column 421, a top plate 422, a first lifting cylinder 423, and a lifting plate 424. Columns 421 are provided at the four corners of the workbench 7. The top ends of the columns 421 are connected to the top plate 422. Above the top plate 422, the first lifting cylinder 423 is fixed.

The rotary joint 432 is connected to an external air source and is connected to the fixing plate 426 through a joint connecting seat. When the air blowing column 431 rotates and blows air, the external air source connecting pipe connected to the rotary joint 432 will not rotate along with it. The connecting pipe 4311 is also rotatably connected to the fixing plate 426 through a rotating mechanism.

[0043] In the above structure, the rotating mechanism includes a servo motor 433 and a bearing fixing plate 434. Below the fixing plate 426, the bearing fixing plate 434 is connected through a connecting column. Bearing seats are provided at both ends of the connecting pipe 4311. One bearing seat is connected to the fixing plate 426 and the other bearing seat is connected to the bearing fixing plate 434. A synchronous pulley 435 is also provided on the connecting pipe 4311 between the two bearing seats. The servo motor 433 is provided above the fixing plate 426 and drives the connecting pipe 4311 to rotate through synchronous belt transmission. By rotating the air blowing column 431 through the rotating mechanism, the air blowing area can be increased and the dust removal effect can be improved. When the first lifting cylinder 423 extends, it drives the connecting seat 425 to descend. The connecting seat 425 drives the fixing plate 426 fixedly connected to it to descend. The descent of the fixing plate 426 drives the lifting plate 424 to slide along the column 421 and drives the upper cover 41, the air blowing column 431, and the ion air nozzle 441 to move downward. When the lifting mechanism 42 stops, the lower end of the air blowing column body 4312 extends into the inner hole of the stator and some air blowing holes are located above the stator, which is conducive to the cleaning of the inside and top of the stator.

[0044] In addition, the electrostatic dust removal mechanism 44 includes an ion generator 441 and an ion nozzle 442. The ion generator 441 is fixed above the top plate 422. There are multiple ion nozzles 442, which are connected to the ion generator 441 through ion air ducts 443.

The ion nozzles 442 are arranged on the side of the bearing fixing plate 434, and the bearing fixing plate 434 has multiple mounting holes on the side of the bearing fixing plate 434. The ion nozzles 442 can be adjusted and mounted on the bearing fixing plate 434 through the mounting holes. This ion nozzle is easy to install and has a good cleaning effect.

[0045] like Figures 6-7 As shown, the second lifting mechanism 52 includes a second lifting cylinder 521 and a lower cover connecting plate 522.

The outer side of the guide rod 523 is sleeved with a linear bearing fixed to the workbench 7. The lower cover 51 is fixed to the lower cover connecting plate 522. During dust removal, the second lifting cylinder 521 extends, driving the guide rod 523 to move upward, thereby driving the lower cover connecting plate 522 and the lower cover 51 to move upward, cooperating with the downwardly moving upper cover 41 to form a dust removal chamber.
