Description

Technical Field

[0001] This invention relates to the field of automated motor assembly equipment, and in particular to a rotor worm gear housing assembly machine and its assembly method. Background Technology

[0002] In the motor assembly process, a worm gear needs to be press-fitted onto the rotor. The rotor has a rotor shaft, and the worm gear is ultimately press-fitted onto the rotor shaft. Then, the housing and the rotor with the worm gear are press-fitted together. Existing technologies for pressing the rotor and worm gear lack guidance during rotor descent, making rotor position prone to misalignment. Worm gear feeding cannot be precisely controlled, affecting work efficiency. Furthermore, existing technologies for pressing the housing and rotor are prone to positional misalignment during housing pressing, resulting in a high rate of defective products. Therefore, there is an urgent need to develop a rotor-worm gear housing assembly machine and its assembly method to meet practical application needs. Summary of the Invention

Detailed Implementation

[0040] The present invention is as follows Figures 1 to 14As shown, a rotor and worm gear housing assembly machine includes a frame 10, a synchronous material transfer mechanism 20 for equidistant transport of rotors, a pressing mechanism 30 for pressing the rotor and worm gear, a bending mandrel detection mechanism 40 for bending mandrel detection of the rotor, a defective product transfer mechanism 50 for transferring defective products, an oiling detection mechanism 60 for oiling and photographic detection of the rotor, a pressing and securing mechanism 70 for conveying the housing and pressing the housing to the rotor and worm gear, a barcode labeling mechanism 80 for affixing QR codes to the housing, a defective product transfer mechanism 90 for conveying defective products, and a qualified product transfer mechanism 100 for conveying qualified products.

[0041] The frame 10 is equipped with a workbench 11 for installing the synchronous transfer mechanism 20; the pressing mechanism 30, bending mandrel detection mechanism 40, defective product transfer mechanism 50, oiling detection mechanism 60, pressing mechanism 70, labeling mechanism 80, defective product transfer mechanism 90 and qualified product transfer mechanism 100 are distributed sequentially along the transfer direction of the synchronous transfer mechanism 20.

[0042] By employing a synchronous material transfer mechanism 20, a pressing mechanism 30, a bending mandrel detection mechanism 40, a defective product transfer mechanism 50, an oiling detection mechanism 60, a pressing and securing mechanism 70, a labeling mechanism 80, a defective product transfer mechanism 90, and a qualified product transfer mechanism 100, the movement of the rotor, the pressing and securing of the rotor worm, the detection of the rotor's bending mandrel, the transfer of defective products, the oiling and detection of the rotor, the pressing and securing of the casing and the rotor, the labeling of the casing, the transfer of defective products, and the transfer of qualified products are all automated. This improves the pressing accuracy and reduces the defect rate.

[0043] The synchronous material transfer mechanism 20 includes a feeding plate for placing several rotors, a lifting drive cylinder 21, a transverse drive cylinder 22, a longitudinal drive cylinder 23, and a clamping cylinder 24 for clamping the rotors. The transverse drive cylinder 22 is installed at the output end of the lifting drive cylinder 21, the longitudinal drive cylinder 23 is installed at the output end of the transverse drive cylinder 22, and the clamping cylinder 24 is installed at the output end of the longitudinal drive cylinder 23. The clamping cylinder 24 is movable and corresponds to the feeding plate. The movement of the clamping cylinder 24 moves the rotors on the feeding plate forward synchronously at equal distances, resulting in high rotor movement consistency.

[0044] The pressing mechanism 30 includes a base plate 31, a feeding assembly 32 for feeding the worm gear, a transfer assembly 33 for transferring the worm gear, and a pressing assembly 34 for pressing the worm gear onto the rotor, wherein:

[0045] The feeding assembly 32 has a discharge cylinder 325 for worm gear discharge and an opening and closing device for opening or closing the discharge cylinder 325; the transfer assembly 33 has a discharge slide 332 for placing the worm gear; the pressing assembly 34 has a discharge slide 346 for placing the rotor; the opening and closing device corresponds to the lower end of the discharge cylinder 325; the discharge slide 332 is movable and corresponds to the discharge cylinder 325; the discharge slide 346 is descendable and located above the discharge slide 332; the rotor descends with the discharge slide 346, and the worm gear is sleeved on the rotor.

[0046] The feeding assembly 32 feeds the worm gear, and the opening and closing device opens the opening end of the discharge cylinder 325. The worm gear leaks out from the discharge cylinder 325 and onto the discharge slide 332 of the transfer assembly 33. The discharge slide 332 drives the worm gear to move to the bottom of the pressing assembly 34. The discharge slide 346 of the pressing assembly 34 drives the rotor to descend. As the rotor descends, the worm gear is gradually fitted onto the lower end of the rotor, completing the pressing of the rotor and worm gear.

[0047] By employing the feeding assembly 32, the transfer assembly 33, and the pressing assembly 34, the feeding, transfer, and pressing of the rotor worm are automated, thereby improving the pressing accuracy.

[0048] The feeding assembly 32 also includes a mounting plate 321, a rotary drive motor 322, a rotating disk 323, and several feeding pipes 324 for placing worm gears. The rotary drive motor 322 is mounted on the mounting plate 321, the rotating disk 323 is mounted on the shaft end of the rotary drive motor 322, and the rotating disk 323 is rotatably located on the mounting plate 321. The several feeding pipes 324 are distributed around the circumference of the rotating disk 323.

[0049] The discharge cylinder 325 and the opening and closing device are both located on the lower surface of the mounting plate 321. The opening and closing device includes a telescopic spring 326 and a cover plate 327. The cover plate 327 is connected to the front end of the telescopic spring 326. The cover plate 327 can extend forward or retract to close or open the discharge cylinder 325.

[0050] The material feeding slide 332 is provided with two abutting posts 333 for abutting against the cover plate 327. The two abutting posts 333 abut against the two side walls of the cover plate 327 respectively.

[0051] A rotary drive motor 322 drives a rotating disk 323 to rotate, and several discharge pipes 324 rotate with the rotating disk 323. When the discharge pipe 324 rotates to the position of the discharge cylinder 325, the abutment post 333 moves with the discharge slide 332 and abuts against the side wall of the cover plate 327, pushing the cover plate 327 backward. The worm gear leaks out from the discharge cylinder 325 and to the discharge position of the discharge slide 332. The discharge slide 332 transfers the caught worm gear to the bottom of the pressing assembly 34. When the worm gear is not being removed, the telescopic spring 326 drives the cover plate 327 to cover the discharge cylinder 325. By adopting an opening and closing device, the automatic opening and closing of the discharge cylinder 325 is realized, the material picking of the worm gear is precisely controlled, and the feeding accuracy is improved.

[0052] The feeding slide 332 is vertically provided with a guide rod 334 for guiding the rotor during its descent. The guide rod 334 is vertically positioned on the feeding slide 332. A sliding block 335 and a displacement sensor 336 are provided below the guide rod 334. The guide rod 334 can be lowered to abut against the sliding block 335, and the displacement sensor 336 corresponds to the sliding block 335.

[0053] The rotor descends with the feeding slide plate 346, and the lower end of the rotor abuts against the upper end of the guide rod 334. The guide rod 334 is spring-loaded and can be raised and lowered on the feeding slide 332. The guide rod 334 descends with the rotor and abuts against the sliding block 335. The displacement sensor 336 senses the position of the sliding block 335 as it descends, thereby determining the position of the rotor and worm gear during pressing and judging whether the pressing is in place, thus improving the pressing accuracy. By using the guide rod 334 to guide the rotor, the position deviation of the rotor during descent is prevented, thus improving the pressing accuracy.

[0054] The transfer assembly 33 also includes a transfer drive cylinder 331, which is mounted on the base plate 31. The discharge slide 332 is mounted on the output end of the transfer drive cylinder 331. The transfer drive cylinder 331 drives the discharge slide 332 to move, thereby satisfying the position movement requirements of the worm gear on the discharge slide 332.

[0055] The pressing assembly 34 also includes a bracket 341, an electric cylinder 342, a pressing head 343, and a pressing column 345. The electric cylinder 342 is mounted on the upper side of the bracket 341, and the pressing head 343 and the pressing column 345 are both mounted on the shaft end of the electric cylinder 342. The discharge slide plate 346 is liftably mounted on the lower side of the bracket 341, the pressing column 345 can be lowered to abut against the discharge slide plate 346, and the pressing head 343 can be lowered to abut against the upper surface of the rotor.

[0056] The pressure head 343 is detachably provided with an abutment block 344 for preventing wear of the pressure head 343. The abutment block 344 can be lowered to abut against the upper surface of the rotor.

[0057] The pressure head 343 presses the upper surface of the rotor, the pressure column 345 abuts against the discharge slide plate 346, and the electric cylinder 342 drives the pressure head 343 and the pressure column 345 to descend synchronously. The rotor descends to achieve the pressing of the rotor and the worm gear. The pressure head 343 presses down on the rotor. The upper end of the rotor is prone to wear on the pressure head 343. A detachable abutment block 344 is used to prevent wear on the pressure head 343 and reduce maintenance costs.

[0058] The bending center detection mechanism 40 includes a detection bracket 41, a vertical drive cylinder 42, a vertical sliding seat 43, a rotary motor 44, a drive wheel 45, several driven wheels 46, a transmission belt 47, and a position sensor 48. The vertical drive cylinder 42 is mounted on the detection bracket 41, the vertical sliding seat 43 is mounted on the shaft end of the vertical drive cylinder 42, the rotary motor 44 is mounted on the vertical sliding seat 43, the drive wheel 45 is sleeved on the shaft end of the rotary motor 44, the transmission belt 47 loops around the drive wheel 45 and several driven wheels 46, and the position sensor 48 is located beside the rotor.

[0059] The rotor is located on the synchronous material transfer mechanism 20. The vertical drive cylinder 42 drives the vertical sliding seat 43 to move vertically, so that the conveyor belt abuts against the shaft end of the rotor. The rotary motor 44 drives the transmission belt 47 to move through the drive wheel 45 and several driven wheels 46. The movement of the transmission belt 47 causes the shaft end of the rotor to rotate. The position sensor 48 detects the position of the shaft end of the rotor when it rotates and detects the degree of bending of the rotor. The bending detection mechanism 40 has a compact overall structure, occupies little area, and has high detection accuracy.

[0060] Defective products that fail inspection are transferred to defective product transfer facility 50.

[0061] The oil dotting detection mechanism 60 includes an oil dotting detection longitudinal movement drive assembly 61, an oil dotting detection vertical movement drive assembly 62, an oil dotting pipe 63, and a CCD detection camera 64. The oil dotting detection vertical movement drive assembly 62 is installed at the output end of the oil dotting detection longitudinal movement drive assembly 61, and the oil dotting pipe 63 and the CCD detection camera 64 are both installed at the output end of the oil dotting detection vertical movement drive assembly 62.

[0062] Both the longitudinal and vertical displacement drive components 61 and 62 for oil dispensing detection include a moving drive cylinder and a sliding plate, which is mounted on the shaft end of the moving drive cylinder. The longitudinal and vertical displacement drive components 61 and 62 first drive the oil dispensing pipe 63 to the rotor position, dispensing oil onto the rotor. An oil collection tank is placed below the rotor to prevent contamination from oil leakage. After oil dispensing is completed, the longitudinal and vertical displacement drive components 61 and 62 drive the CCD detection camera 64 to the rotor position, taking a picture of the rotor to detect whether oil has been dispensed. The use of the CCD detection camera 64 improves the accuracy of oil dispensing and prevents omissions.

[0063] The clamping mechanism 70 includes a clamping and conveying assembly 71 and a pressing assembly 72. The pressing assembly 72 includes a pressing drive motor 721, a pressing drive screw, a lifting clamping block 722, a telescopic cylinder 723, and a stop block 724. The pressing drive screw is mounted on the shaft end of the pressing drive motor 721 and is rotatably engaged with the lifting clamping block 722. The telescopic cylinder 723 and the stop block 724 are both connected to the lifting clamping block 722. The stop block 724 is mounted on the shaft end of the telescopic cylinder 723 and is movable to abut against the front side of the lifting clamping block 722.

[0064] The pressing mechanism 70 also includes a housing conveying assembly, which includes a conveyor motor and a conveyor belt. The conveyor belt is mounted on the shaft end of the conveyor motor. The housing conveying assembly conveys the housing to the pressing and transporting assembly 71. The pressing and transporting assembly 71 transports the housing to the pressing assembly 72. The pressing assembly 72 presses the housing down into the rotor, thus pressing the rotor and the housing together.

[0065] The pressing and conveying assembly 71 moves the machine housing onto the lifting clamping block 722. The telescopic cylinder 723 drives the stop block 724 to press against the machine housing. The downward driving motor 721 drives the lifting clamping block 722 to descend. The stop block 724 abuts against the machine housing. As the lifting clamping block 722 descends, the machine housing will then be assembled with the rotor on the synchronous material transfer mechanism 20.

[0066] The press-fitting of the housing and rotor is achieved by using the pressing assembly 72, and the stop block 724 abuts against the side wall of the housing to prevent the housing from shifting position during descent, thereby reducing the press-fitting defect rate.

[0067] The labeling mechanism 80 includes a feeding assembly 81 and a picking and transferring assembly 82, which is located between the feeding assembly 81 and the synchronous transferring mechanism 20. The feeding assembly 81 includes a feeding bracket 811, a feeding tray 812, several tension rollers 813, a peeling plate 814, a rotary motor 815, and a winding reel 816. The feeding tray 812 is mounted on the feeding bracket 811, and the several tension rollers 813 are mounted on the feeding bracket 811 at intervals. The front end of the peeling plate 814 has an inclined surface to facilitate the peeling of the QR code label, and the winding reel 816 is mounted on the shaft end of the rotary motor 815.

[0068] The QR code label is in the form of a strip on the feeding tray 812. The QR code label strip is divided into a carrier layer and a QR code label layer pasted on the carrier layer. The QR code label is individually pasted on the carrier layer. The strip passes through several tension rollers 813. The inclined surface at the front end of the peeling plate 814 peels the QR code label off from the carrier layer. The rotating motor 815 drives the winding tray 816 to wind up the carrier layer.

[0069] The material handling and transfer assembly 82 includes a longitudinal transfer drive device 821, a vertical transfer drive device 822, a rotary cylinder 823, and a vacuum suction cup 824. The vertical transfer drive device 822 is installed at the output end of the longitudinal transfer drive device 821, the rotary cylinder 823 is installed at the output end of the vertical transfer drive device 822, and the vacuum suction cup 824 is installed at the shaft end of the rotary cylinder 823.

[0070] The vacuum suction cup 824 picks up the peeled individual QR code labels. The vertical drive device 821, the vertical drive device 822, and the rotary cylinder 823 drive the vacuum suction cup 824 to move and rotate, attaching the QR code labels to the surface of the machine housing. By using the feeding component 81 and the picking and transferring component 82, the feeding and picking and transferring of QR code labels are realized. The position movement is highly accurate, reducing the defect rate.

[0071] Both the longitudinal material transfer drive device 821 and the vertical material transfer drive device 822 include a moving drive motor, a drive screw, and a sliding seat. The drive screw is mounted on the shaft end of the moving drive motor and rotates with the sliding seat.

[0072] Both the defective product transfer mechanism 50 and the defective product conveying mechanism 90 include a transfer and handling assembly and a conveying assembly. Both the qualified product conveying mechanism 100 and the conveying assembly include a drive motor and a conveyor belt. Both the transfer and handling assembly and the pressing and handling assembly 71 include a longitudinal handling device 711, a vertical handling device 712, and a gripper cylinder 713. The vertical handling device 712 is installed at the output end of the longitudinal handling device 711, and the gripper cylinder 713 is installed at the output end of the vertical handling device 712. The defective product transfer mechanism 50 also includes a transverse material transfer drive cylinder 51 and a vertical material transfer drive cylinder 52. The vertical transfer drive cylinder 52 is installed at the output end of the horizontal transfer drive cylinder 51, and the receiving seat 53 is installed at the shaft end of the vertical transfer drive cylinder 52. The receiving seat 53 moves horizontally and vertically under the drive of the horizontal transfer drive cylinder 51 and the vertical transfer drive cylinder 52, moving the rotor transported by the transport component to the conveying component for transport. Both the longitudinal transport device 711 and the vertical transport device 712 include a motor, a lead screw, and a slide. The lead screw is installed at the shaft end of the motor, and the slide rotates with the lead screw. Alternatively, a cylinder and a slider can be used, with the slider installed at the shaft end of the cylinder.

[0073] The assembly method of this rotor worm gear housing assembly machine includes the following steps:

[0074] First, the synchronous material transfer mechanism moves the rotor forward at equal distances. When the rotor is moved to the side of the pressing mechanism, the pressing mechanism presses the rotor and the worm gear together.
