Description

Technical Field

[0001] This invention belongs to the field of electric motor manufacturing technology, specifically relating to a feeding device for an electric motor cover. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a rotating magnetic field generated by an energized coil (i.e., the stator winding) to act on the rotor (such as a squirrel-cage closed aluminum frame), creating a magnetoelectric torque. Electric motors are classified into DC motors and AC motors according to the type of power source they use.

[0003] During the production process of electric motors, the covers at both ends need to be assembled. Most of the existing equipment for feeding the covers is a conveyor belt. When the conveyor belt feeds the electric motor cover, a robotic arm is used to clamp the electric motor cover on the conveyor belt to the assembly station.

[0004] However, when existing conveyor belts are used to load and transport motor covers, the conveyor belts often deform under the pressure of the motor covers. When the conveyor belt deforms, the position of the motor cover being transported on the conveyor belt shifts, resulting in reduced gripping accuracy of the robotic arm and, in severe cases, damage to the robotic arm. This phenomenon has become a problem that urgently needs to be solved by those in the field. Summary of the Invention

[0053] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0054] Please see Figure 1-12The present invention provides a technical solution: a feeding device for motor cover, including a feeding system 1, a first robotic arm 2, a second robotic arm 7 and an external controller. A placement rack 6 is provided on one side of the feeding system 1. The placement rack 6 is used to store defective motor covers. The feeding system 1 includes a mounting frame 14. Rollers 12 are provided at both ends of the mounting frame 14. Rotating rods 11 are fixedly connected to both ends of the rollers 12. Conveyor belts 13 are sleeved on the rotating rods 11 at both ends.

[0055] The conveyor belt 13 is provided with an adjustment component, which is used to prevent the conveyor belt 13 from deforming when feeding the motor cover;

[0056] The adjustment assembly includes a mounting frame 5, with both ends of the mounting frame 5 fixedly connected to the inner walls of the two sides of the mounting frame 14. The lower part of the conveyor belt 13 is located inside the mounting frame 5. An adjustment drive component 51 is fixedly connected to the upper surface of the mounting frame 5. The adjustment drive component 51 is vertically positioned relative to the upper surface of the mounting frame 5. The output end of the adjustment drive component 51 faces upward and is fixedly connected to an adjustment plate 52. An installation groove 521 is provided on the adjustment plate 52. A pressure sensor 522 is fixedly installed inside the installation groove 521. The pressure sensor 522 is connected to a controller (not shown in the figure). Three sets of adjustment drive components 51 are evenly distributed in a horizontal array on the upper surface of the mounting frame 5.

[0057] It should be noted that the adjustment drive component 51 can be a cylinder, and the first robotic arm 2 is existing technology (such as an industrial robotic arm), which will not be elaborated on in this article.

[0058] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The mounting frame 14 is used to install the roller shaft 12. The rotating rod 11 on the side away from the first robotic arm 2 is fixedly connected to the output shaft of the motor. The rotating rods 11 at both ends of the mounting frame 14 are driven by a belt (not shown in the figure), thereby driving the conveyor belt 13 to rotate and realize the purpose of feeding the motor cover.

[0059] The adjusting drive 51 moves the adjusting plate 52 vertically by extending and retracting its output end. A pressure sensor 522, fixedly connected inside the mounting slot 521, detects the pressure at that point on the conveyor belt 13. When the pressure sensor reading exceeds a preset value, to prevent deformation of the conveyor belt 13 under pressure, which could cause the motor cover to shift on the conveyor belt 13, the adjusting drive 51, under the control of the controller, moves the adjusting plate 52 vertically upwards until its upper surface slides into contact with the bottom of the conveyor belt 13. The adjusting plate 52 then supports the conveyor belt 13 at the point of excessive pressure. Simultaneously, the controller (not shown) adjusts the other two adjusting drives 51 in the feeding direction of the motor cover synchronously to prevent the excessively heavy motor cover from deforming the conveyor belt 13.

[0060] An auxiliary frame 53 is fixedly connected to the mounting frame 5. Two auxiliary frames 53 are arranged in a group, and the two auxiliary frames 53 are symmetrically arranged on both sides of the adjusting drive component 51. A cavity 531 is opened in the auxiliary frame 53. A first spring 535 is fixedly connected to the auxiliary frame 53. A slide plate 532 is slidably connected to the auxiliary frame 53. One end of the first spring 535 is fixedly connected to the upper surface of the mounting frame 5, and the other end of the first spring 535 is fixedly connected to the lower surface of the slide plate 532. A connecting post 534 is fixedly connected to the upper surface of the slide plate 532. The top of the connecting post 534 is fixedly connected to the lower surface of the adjusting plate 52. A limit plate 533 is fixedly connected to the auxiliary frame 53. The limit plate 533 is slidably connected to the connecting post 534. Ventilation holes 536 are opened on all four sides of the auxiliary frame 53.

[0061] refer to Figure 4 and Figure 5 The connecting column 534 fixedly connected to the slide plate 532 can provide auxiliary support for the adjusting plate 52 when it moves up and down, making the force on the adjusting plate 52 more even and preventing the adjusting plate 52 from tilting due to uneven force. When the adjusting plate 52 moves vertically downward, the adjusting plate 52 drives the connecting column 534 to move vertically downward. At this time, the first spring 535 inside the auxiliary frame 53 deforms after being compressed. The slide plate 532 moves downward inside the auxiliary frame 53, and the slide plate 532 discharges the air inside the auxiliary frame 53 to the outside through the ventilation hole 536. The air discharged to the outside of the auxiliary frame 53 can drive the air flow inside the conveyor belt 13 to a certain extent, thereby playing a role in heat dissipation on the inner wall of the conveyor belt 13 and also playing a certain role in buffering the vibration of the conveyor belt 13, reducing the vibration amplitude of the conveyor belt 13, and thus ensuring that the position of the motor cover on the conveyor belt 13 is relatively stable.

[0062] The conveyor belt 13 is equipped with a sorting visual screening box 4.

[0063] It should be noted that the sorting vision screening box 4 is existing technology. It uses its built-in algorithm program and shooting unit to identify the front cover and rear cover of the motor. The rear cover of the motor has heat dissipation windows and through holes for fixing the heat dissipation windows, which will not be described in detail in this application.

[0064] refer to Figure 1 The front and rear covers of the electric motor are simultaneously transported and loaded on the conveyor belt 13. The front and rear covers of the electric motor are identified by the built-in algorithm program and shooting unit of the sorting vision screening box 4, and then the first robotic arm 2 is used to load the front and rear covers respectively.

[0065] A front cover inspection assembly for inspecting the front cover of the motor is provided on one side of the conveyor belt 13. The front cover inspection assembly is used to inspect the qualification of the holes on the front cover of the motor. The front cover inspection assembly includes a front cover inspection box 3, which is equipped with a front cover inspection unit, a front cover lifting unit, a front cover clamping unit and a front cover processing unit.

[0066] The front cover detection unit includes a first drive 31, which is fixedly connected to the inner bottom surface of the front cover detection box 3. The first drive 31 is perpendicular to the inner bottom surface of the front cover detection box 3. The output end of the first drive 31 is fixedly connected to a support plate 32. A standard rod 35 is fixedly connected to the upper surface of the support plate 32. The standard rod 35 is used to detect the holes on the front cover of the motor. The standard rod 35 consists of an upper straight rod and a lower tapered rod. First side plates 321 are fixedly connected to both sides of the support plate 32. Laser sensors 322 are fixedly connected to both sides of the first side plates 321.

[0067] It should be noted that the first drive 31 can be a cylinder.

[0068] refer to Figure 8 , Figure 9 and Figure 10 The first drive 31 drives the carrier plate 32 to move up and down through the extension and retraction of the output end. The laser sensor 322 consists of a laser emitter and a laser receiver. Two sets of laser sensors 322 are provided, and the two sets of laser sensors 322 are arranged at different heights in the vertical direction of the first side plate 321.

[0069] The straight bar portion of the standard bar 35 is the standard value, and the conical bar portion of the standard bar 35 is the test value. If the hole on the motor cover can be inserted into the straight bar portion of the standard bar 35 without contacting the conical bar portion, then the hole position parameter on the motor cover is qualified.

[0070] If the hole on the motor cover allows insertion of the straight rod portion of the standard rod 35, but the bottom of the motor cover is in contact with the conical rod portion:

[0071] When the lowest point of the contact line between the bottom of the motor cover and the cone bar is located between the two sets of laser sensors 322 on the same side, the hole position of the motor cover is within the qualified range and feeding can continue.

[0072] If the lowest point of the contact line between the bottom of the motor cover and the cone bar is lower than the lowest point of the two sets of laser sensors 322 on the same side, then the hole of the motor cover is too large and exceeds the qualified range. Then the first robotic arm 2 is controlled by the controller (not shown in the figure) to move it to the waste area for centralized processing.

[0073] The front cover lifting unit includes a second drive 33, which is vertically arranged between the second drive 33 and the support plate 32, and the output end of the second drive 33 is fixedly connected to the lifting plate 331.

[0074] It should be noted that the second drive 33 can be a cylinder.

[0075] refer to Figure 8 , Figure 9 and Figure 10 After the motor cover is detected by the detection unit, the extension and retraction of the output end of the second drive 33 drives the lifting plate 331 to move vertically upward, and removes the detected motor cover from the support plate 32.

[0076] The front cover clamping unit includes a fourth drive 36, and there are two sets of fourth drives 36. The two sets of fourth drives 36 are symmetrically arranged on both sides of the lifting plate 331. Each set of fourth drives 36 is perpendicular to the inner side wall of the front cover detection box 3. The output end of the fourth drive 36 is fixedly connected to the front cover clamping plate 361.

[0077] It should be noted that the fourth drive 36 can be a cylinder.

[0078] refer to Figure 9 and Figure 10 When the front cover of the motor needs to be processed after inspection, the fourth drive 36 on both sides drives the front cover clamping plates 361 on both sides to move toward the motor cover and clamp it through the extension and retraction of the output shaft.

[0079] The front cover processing unit includes a third drive 34, which is fixedly connected to the inner top surface of the front cover detection box 3. The output shaft of the third drive 34 is vertically downward, and a top plate 341 is fixedly connected to the output shaft of the third drive 34. An industrial camera 38 is fixedly connected to the lower surface of the top plate 341. Second side plates 3411 are fixedly connected to both sides of the top plate 341. A threaded rod 3412 is rotatably arranged between the two second side plates 3411. A rotation drive component 3415 is fixedly connected to one of the second side plates 3411. A slider 3413 is threaded onto the threaded rod 3412. A flat plate 3414 is fixedly connected to the bottom of the slider 3413. A square plate is fixedly connected to the bottom of the flat plate 3414. A fifth drive 37 is fixedly connected to the square plate. A mounting plate 371 is fixedly connected to the output end of the fifth drive 37. A sixth drive 372 is fixedly connected to the bottom of the mounting plate 371. The output shaft of the sixth drive 372 is vertically downward and fixedly connected to a processing drive 373. A grinding rod 374 is fixedly connected to the bottom of the processing drive 373.

[0080] It should be noted that the third drive 34, the fifth drive 37, and the sixth drive 372 can be cylinders. The processing drive 373 and the rotation drive 3415 can be motors.

[0081] refer to Figure 10 , Figure 11 and Figure 12 The third drive 34 moves the top plate 341 by extending and retracting its output shaft in the vertical direction; the fifth drive 37 moves the grinding rod 374 horizontally by extending and retracting its output end; the sixth drive 372 moves the grinding rod 374 vertically by extending and retracting its output end; the rotation drive 3415 moves the threaded rod 3412 horizontally by rotating its output end, and the threaded rod 3412 indirectly moves the slider 3413 horizontally. Figure 12 As shown, the slider 3413 is slidably connected to the limiting groove (not labeled in the figure) opened on the top plate 341 to prevent the slider 3413 from rotating when moving horizontally. The industrial camera 38 is set directly above the hole in the front cover of the motor. When the hole in the motor cover cannot be inserted into the straight bar part of the standard bar 35, the industrial camera 38 identifies the hole.

[0082] If there are burrs in the holes of the motor front cover, the grinding rod 374 in the processing unit is controlled by the controller (not shown in the figure) to grind the inner diameter of the hole. After grinding, the ground motor cover is put into the front cover detection unit for detection again. The second detection can be performed through the above detection steps.

[0083] A front cover conveyor belt 8 is provided on one side of the conveyor belt 13. A front cover visual defect detection box 81 is fixedly connected to the front cover conveyor belt 8. The second robotic arm 7 is located on the same side of the front cover conveyor belt 8.

[0084] It should be noted that the front cover conveyor belt 8 and the front cover visual defect detection box 81 are both existing technologies, and will not be described in detail in this application.

[0085] It should be added that the second robotic arm 7 is existing technology (such as an industrial robotic arm), which is operated by a hydraulic system, and will not be described in detail in this application.

[0086] refer to Figure 1 After the front cover of the motor passes the inspection by the front cover inspection box 3, the hydraulic system is controlled by an external controller (not shown in the figure). The hydraulic system controls the first robotic arm 2 to remove the inspected front cover of the motor from the front cover inspection box 3 and place it on the front cover conveyor belt 8 for transportation. During the transportation of the front cover of the motor, a high-pixel camera built into the front cover visual defect inspection box 81, which is fixedly connected to the front cover conveyor belt 8, is used to detect whether there are scratches on the surface of the front cover of the motor.

[0087] If the front cover visual defect detection box 81 detects that the surface of the motor front cover is intact and there are no scratches, then the front cover conveyor belt 8 will continue to transport and feed it.

[0088] If the front cover visual defect detection box 81 detects scratches on the surface of the motor front cover, the hydraulic system is controlled by an external controller (not shown in the figure), and the second robotic arm 7 is used to remove the defective motor front cover from the front cover visual defect detection box 81 and place it on the placement rack 6 for centralized processing.

[0089] A rear cover inspection box 10 is provided on the side of the conveyor belt 13 away from the front cover inspection box 3. The rear cover inspection box 10 is used to inspect the position of the heat dissipation window on the rear cover of the motor and the hole position for installing the heat dissipation window. The rear cover inspection box 10 is provided with a rear cover inspection unit and a rear cover clamping unit.

[0090] The rear cover detection unit includes an eighth drive 103, which is installed perpendicularly to the inner bottom surface of the rear cover detection box 10. A detection plate 104 is fixedly connected to the output shaft of the eighth drive 103, and a detection block 105 is fixedly connected to the detection plate 104. Go / no-go gauges 106 are fixedly connected to all four sides of the detection block 105.

[0091] It should be noted that the eighth drive 103 can be a cylinder.

[0092] It should be added that the position of the detection block 105 connected to the detection plate 104 is compatible with the position and specifications of the heat dissipation window on the rear cover of the motor, and the installation position of the go / no-go gauge 106 connected to the detection plate 104 is compatible with the hole specifications on the rear cover of the motor for installing the heat dissipation window.

[0093] refer to Figure 6The eighth drive 103 drives the detection plate 104 to move up and down by extending and retracting its output shaft in the vertical direction. The detection block 105 is used to detect the opening position of the heat dissipation window on the rear cover of the motor. The go and no-go gauge 106 is used to detect the hole position of the fixed heat dissipation window.

[0094] The rear cover clamping unit includes a seventh drive 101. Two sets of seventh drives 101 are symmetrically arranged inside the rear cover detection box 10. Each set of seventh drives 101 is perpendicular to the inner side wall of the rear cover detection box 10. A rear cover clamping plate 102 is fixedly connected to the output end of the seventh drive 101.

[0095] It should be noted that the seventh drive 101 can be a cylinder.

[0096] refer to Figure 6 Both sides of the seventh drive 101 drive the rear cover clamping plate 102 to move horizontally through the extension and retraction of its output end, thereby clamping and positioning the rear cover of the motor to be tested.

[0097] A rear cover conveyor belt 9 is provided on one side of the conveyor belt 13. A rear cover visual defect detection box 91 is fixedly connected to the rear cover conveyor belt 9. The rear cover conveyor belt 9 and the front cover conveyor belt 8 are located on the same side of the conveyor belt 13.

[0098] It should be noted that the rear cover conveyor belt 9 and the rear cover visual defect detection box 91 are both existing technologies, and will not be described in detail in this application.

[0099] refer to Figure 1 and Figure 6 If the detection block 105 in the rear cover detection box 10 can be fitted with the position of the heat dissipation window on the rear cover, and the go / no-go gauge 106 can be inserted into the hole on the rear cover to fix the heat dissipation window, then the opening position of the motor rear cover hole is qualified. The hydraulic system is controlled by the external controller (not shown in the figure), and the first robotic arm 2 is used to take the qualified motor rear cover out of the rear cover detection box 10 and place it on the rear cover conveyor belt 9 for conveying and feeding.

[0100] After the position of the hole in the rear cover of the motor is inspected and approved, during the transportation and loading process on the rear cover conveyor belt 9, the rear cover visual defect detection box 91 uses a high-pixel camera built into it to detect whether there are scratches on the surface of the rear cover of the motor.

[0101] If the rear cover visual defect detection box 91 detects that the surface of the motor rear cover is intact and there are no scratches, then the rear cover conveyor belt 9 will continue to transport and feed it.

[0102] If the rear cover visual defect detection box 91 detects scratches on the surface of the motor rear cover, the hydraulic system is controlled by an external controller (not shown in the figure), and the second robotic arm 7 is used to remove the defective motor rear cover from the rear cover visual defect detection box 91 and place it on the placement rack 6 for centralized processing.

[0103] The mounting bracket 14 is provided with a tensioning assembly, which includes a fixed plate 141. The fixed plate 141 is fixedly connected to the mounting bracket 14. A tensioning drive component 142 is fixedly connected to the fixed plate 141. A connecting rod 144 is fixedly connected to the output end of the tensioning drive component 142. A bushing 143 is fixedly connected to the connecting rod 144. The bushing 143 is rotatably sleeved on the rotating rod 11.

[0104] It should be noted that the tensioning drive component 142 can be a cylinder.

[0105] refer to Figure 1 and Figure 12 The tensioning drive 142 drives the rotating rod 11 to move horizontally through the extension and retraction of the output end, thereby tensioning the conveyor belt 13 sleeved on the roller 12 to prevent the tension of the conveyor belt 13 from decreasing, which would cause the position of the motor cover to shift.

[0106] The feeding device of this invention can adjust the tension of the conveyor belt 13 through the tensioning component to ensure that the position of the motor cover on the conveyor belt 13 is not offset as much as possible. By setting the adjustment component, the adjustment drive 51 drives the adjustment plate 52 to move in the vertical direction to support the conveyor belt 13 at the point of heavier force, which can further prevent the conveyor belt 13 from deforming when conveying the motor cover, thereby ensuring that the position of the motor cover on the conveyor belt 13 is relatively stable, improving the accuracy of the first robotic arm 2 in grasping the motor cover, and improving the feeding efficiency of the motor cover.
