Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly equipment, and in particular, to an automatic assembly equipment for motor flat square shafts and circlips. Background Art

[0002] In the white goods manufacturing industry, there is a widespread problem of labor-intensive work and high labor intensity. As the "engine" of white goods, the iron-shell motor has a large variety of assembled parts, a large number of parts, and complex processes. In particular, the assembly of the motor flat square shaft and the E-type circlip has high requirements and great difficulty.

[0003] The assembly of the motor flat square shaft and the E-type circlip has very strict requirements for positioning accuracy and reliability. Otherwise, it is easy to cause axial fixing looseness and failure in the terminal installation of the motor, resulting in insufficient torque transmission of the product, abnormal noise and vibration during operation, greatly reduced service life, and poor experience for end-users.

[0004] In the past, workers have always disassembled the packaged E-type circlips and scattered them into the turnover box, transported them to the production line process position, and then manually picked out the E-type circlips one by one, placed them on the hand-held installation tool for fixing, picked up the motor with the other hand, fixed the motor shaft at the same time, visually searched for the circlip groove and the flat square, and installed the E-type circlip in the circlip groove of the motor shaft to ensure that the tongue of the E-type circlip is on the opposite side of the flat square. In order to ensure the assembly position and accuracy, the E-type circlips need to be separated into single ones and fixed on the tool. Since the circlip is made of elastic material, it is very easy to cause the circlip to fly off due to poor control of the force, wasting materials and labor; and when manually assembling, the hands and eyes are used simultaneously, which is very easy to cause fatigue, resulting in unqualified position and accuracy of the tongue of the E-type circlip, and extremely low production efficiency. The whole process is completely manual operation and manual inspection, resulting in misjudgment and missed judgment. It is detected in the terminal equipment and complained by the end-users. However, after the subsequent process, it is disassembled and repaired, causing great waste to the cost and having a negative impact on the brand effect of the product.

[0005] The whole process is time-consuming, laborious, has a large work intensity, uses a lot of labor, and has low production efficiency. And the whole process is completely manual operation, which is easy to cause quality problems. To solve the above defects, the iron-shell motor manufacturing enterprises of white goods have successively sought automatic assembly and detection solutions in the process of "assembly of the flat square shaft of the iron-shell motor and the E-type circlip".

[0006] In view of this, it is necessary to provide an automatic assembly equipment for motor flat square shafts and circlips to solve the above problems. Summary of the Invention

[0037] Please refer to Figures 1 to 3 , the present invention provides an automatic assembly device for a flat square shaft and a snap ring of a motor, including: a feeding assembly line 1, a lifting device 2, a clamping and flipping device 3, a positioning device 4, and an assembly device 5.

[0038] The lifting device 2 is installed below the feeding assembly line 1 and can pass through the feeding assembly line 1. The clamping and flipping device 3 and the assembly device 5 are respectively installed on both sides of the lifting device 2. The positioning device 4 is installed at intervals directly above the lifting device 2.

[0039] The feeding assembly line 1 transfers the iron shell motor 9 to directly above the lifting device 2. The lifting device 2 rises to lift the iron shell motor 9 from the feeding assembly line 1. The clamping and flipping device 3 moves towards the assembly device 5 to clamp the iron shell motor 9. The positioning device 4 moves downward to position the iron shell motor 9 on the lifting device 2. The assembly device 5 approaches the iron shell motor 9 to convey the E-type snap ring 8 to the flat square shaft 91 of the iron shell motor 9 for assembly, so that the E-type snap ring 8 is assembled with the flat square shaft 91. It should be noted that in this embodiment, the lifting device 2 can adopt a hydraulic lifting device 2.

[0040] In this way, the feeding assembly line 1 transfers the iron shell motor 9 to directly above the lifting device 2. The lifting device 2 rises to lift the iron shell motor 9 from the feeding assembly line 1 to a predetermined height. The clamping and flipping device 3 moves towards the assembly device 5 to clamp the iron shell motor 9. The positioning device 4 moves downward to position the iron shell motor 9 on the lifting device 2. The assembly device 5 approaches the iron shell motor 9 to convey the E-type snap ring 8 to a flat square shaft 91 of the iron shell motor 9 for assembly, so that the E-type snap ring 8 is assembled with the flat square shaft 91.

[0041] The positioning device 4 moves upward to its original position to complete the reset. The assembly device 5 moves to its original position to complete the reset. The clamping and flipping device 3 flips the iron shell motor 9 by 180°. The positioning device 4 moves downward again to position the iron shell motor 9 on the lifting device 2. The assembly device 5 approaches the iron shell motor 9 again to convey the E-type snap ring 8 to another flat square shaft 91 of the iron shell motor 9 for assembly, so that the E-type snap ring 8 is assembled with the flat square shaft 91.

[0042] The positioning device 4 moves upward to its original position to complete the reset, the assembling device 5 moves to its original position to complete the reset, the clamping and flipping device 3 flips the iron shell motor 9 by 180° again to return the iron shell motor 9 to its initial state, the clamping and flipping device 3 moves away from the assembling device 5 to its original position to complete the reset, the lifting device 2 moves downward to its original position to complete the reset, and during the downward movement of the lifting device 2, the iron shell motor 9 is placed on the feeding assembly line 1 and conveyed to the next station by the feeding assembly line. Finally, the feeding assembly line 1 moves to its original position to complete the reset.

[0043] In a preferred embodiment, the feeding assembly line 1 includes a line body 11 and a pallet 12 installed on the conveyor belt of the line body 11. The pallet 12 is provided with a card hole 121 for placing the iron shell motor 9, and the conveyor belt of the line body 11 drives the pallet 12 to move, which can play a role in conveying the iron shell motor 9.

[0044] In a preferred embodiment, the clamping and flipping device 3 includes a first telescopic moving member 31, a rotating moving member 32, and a jaw 33. The rotating moving member 32 is connected between the first telescopic moving member 31 and the jaw 33. The first telescopic moving member 31 drives the rotating moving member 32 and the jaw 33 to move towards or away from the assembling device 5, and the rotating moving member 32 drives the jaw 33 to rotate. It should be noted that in this embodiment, the first telescopic moving member 31 uses a telescopic cylinder, and the rotating moving member 32 uses a rotating cylinder.

[0045] In this way, when the first telescopic moving member 31 drives the rotating moving member 32 and the jaw 33 to move towards the assembling device 5, the jaw 33 clamps the iron shell motor 9, and the rotating moving member 32 drives the iron shell motor 9 on the jaw 33 to rotate by 180°.

[0046] In a preferred embodiment, the clamping and flipping device 3 further includes a first mounting plate 34, a first reference plate 35, a first lifter 36, and a first driving member 37. The first mounting plate 34 is spaced below the first reference plate 35. The first reference plate 35 is provided with a support block 351, and the rotating moving member 32 is rotatably mounted on the support block 351. The first lifter 36 is arranged on the first mounting plate 34 and connected to the first reference plate 35. The first driving member 37 is arranged on the first mounting plate 34 and connected to the first lifter 36. The first driving member 37 drives the first lifter 36 to move, so that the first lifter 36 drives the first reference plate 35 to move up and down.

[0047] It should be noted that the first driving member 37 is a servo motor. The first lifter 36 is mainly composed of a worm gear and a worm. The rotating shaft of the first driving member 37 is connected to the worm gear through a coupling. The worm meshes with the worm gear. The rotating shaft of the first driving member 37 drives the worm gear to rotate, and the worm gear drives the worm to move up and down, thereby driving the first reference plate 35 to move up and down to adjust the height of the first reference plate 35, and further facilitating the first reference plate 35 to reach the height of the iron shell motor 9 on the jacking device 2.

[0048] In a preferred embodiment, the clamping and flipping device 3 further includes a first guide rod 38 and a first guide sleeve 39. The first guide rod 38 is inserted and installed on the first mounting plate 34 and the first reference plate 35. The first guide sleeve 39 is installed on the first mounting plate 34. The first guide rod 38 is movably inserted into the first guide sleeve 39.

[0049] In this way, when the rotating shaft of the first driving member 37 drives the worm gear to rotate, and the worm gear drives the worm to move up and down, thereby driving the first reference plate 35 to move up and down, the first guide rod 38 moves up and down in the first guide sleeve 39, preventing the first reference plate 35 from shifting in position during the lifting process.

[0050] Please refer to Figures 4 to 9 , in a preferred embodiment, the positioning device 4 includes a power member 41, a moving member 42, and a positioning member 43. The power member 41 is connected to the moving member 42. The moving member 42 is connected to the positioning member 43. The power member 41 drives the moving member 42 to move, and the moving member 42 drives the positioning member 43 to move up and down.

[0051] It should be noted that in this embodiment, the power member 41 is a servo motor. The moving member 42 is a ball screw pair. The ball screw pair is mainly composed of a screw and a nut installed on the screw. A gear is installed on the nut. The screw is connected to the positioning member 43. The power member 41 drives the nut to rotate through a belt sleeved on the gear, and the nut drives the screw to move up and down, thereby driving the positioning member 43 to move up and down.

[0052] In a preferred embodiment, the positioning member 43 includes a mounting bracket 431, a flat square shaft clamping assembly 432, and a first sensor 433. The mounting bracket 431 is connected to the moving member 42. The flat square shaft clamping assembly 432 is installed on the mounting bracket 431. The first sensor 433 is installed at the bottom of the mounting bracket 431.

[0053] It should be noted that in this embodiment, the flat square shaft clamping assembly 432 is mainly composed of a servo motor 4321 and a three-jaw chuck 4322. After the servo motor 4321 drives the three-jaw chuck 4322 to clamp the flat square shaft 91 through a belt, the servo motor 4321 continues to drive the three-jaw chuck to rotate, thereby changing the direction of the assembly position of the E-type snap ring 8 on the flat square shaft 91; or the servo motor 4321 drives the three-jaw chuck 4322 to release the flat square shaft 91.

[0054] When the moving member 42 drives the mounting bracket 431 of the positioning member 43 to move downward to above the iron shell motor 9 placed on the lifting device 2, and the flat square shaft 91 on the iron shell motor 9 passes through the bottom of the mounting bracket 431 and extends to the flat square shaft clamping assembly 432, the first sensor 433 gradually detects the assembly position of the flat square shaft 91 of the iron shell motor 9 below the mounting bracket 431 during the downward movement of the mounting bracket 431. At this time, the flat square shaft clamping assembly 432 starts to clamp the flat square shaft 91 on the iron shell motor 9, and the servo motor 4321 of the flat square shaft clamping assembly 432 drives the three-jaw chuck 4322 to rotate, changing the direction of the assembly position of the E-type snap ring 8 on the flat square shaft 91 of the iron shell motor 9, so that the direction of the assembly position on the flat square shaft 91 of the iron shell motor 9 is opposite to that of the assembly device 5, facilitating the assembly device to assemble the E-type snap ring 8 at the assembly position of the flat square shaft 91.

[0055] In a preferred embodiment, the positioning member 43 further includes a flat square shaft locking assembly 44 and a second sensor 45. The flat square shaft locking assembly 44 is installed on the mounting bracket 431, and the second sensor 45 is installed on the flat square shaft locking assembly 44. The second sensor 45 is used to detect whether the flat square shaft locking assembly 44 locks the flat square shaft 91 of the iron shell motor 9. Specifically, the flat square shaft locking assembly 44 includes a pneumatic component 441 (such as a cylinder) and a clamping piece 442 connected to the pneumatic component 441. One end of the clamping piece 442 is provided with a bayonet 443, and the second sensor 45 is installed on the clamping piece 442.

[0056] When the servo motor of the flat square shaft clamping assembly 432 drives the three-jaw chuck to rotate, changing the direction of the assembly position of the E-type snap ring 8 on the flat square shaft 91, so that the direction of the assembly position on the flat square shaft 91 is opposite to that of the assembly device 5, the pneumatic component 441 of the flat square shaft assembly drives the clamping piece 442 to move, so that the bayonet 443 of the clamping piece 442 catches the flat square shaft 91 of the iron shell motor 9 to lock the flat square shaft 91 of the iron shell motor 9. After the second sensor 45 detects that the flat square shaft 91 is locked, the assembly device assembles the E-type snap ring 8 on the flat square shaft 91.

[0057] In a preferred embodiment, the assembly device 5 includes a second telescopic moving member 51, a sliding assembly 52, a third telescopic moving assembly 53, and a material storage assembly 54. The second telescopic moving member 51 is connected to the sliding assembly 52. The third telescopic moving assembly 53 is installed on the sliding assembly 52. The material storage assembly 54 is installed on the sliding assembly 52. The second telescopic moving member 51 is connected to the material storage assembly 54 through a connecting rod 55. The second telescopic moving member 51 pushes and pulls the material storage assembly 54 through the connecting rod 55 to drive the sliding assembly 52 to move. The third telescopic moving assembly 53 moves with the sliding assembly 52. The third telescopic moving assembly 53 can also pass through the material storage assembly 54 to convey the E-type circlip 8 on the material storage assembly 54 to the flat square shaft 91 of the iron shell motor 9.

[0058] In a preferred embodiment, the assembly device 5 includes a second mounting plate 56, a second reference plate 57, a second lifter 58, and a second driving member 59. The second mounting plate 56 is spaced and installed below the second reference plate 57.

The second telescopic moving member 51 drives the sliding assembly 52 to move on the second reference plate 57. The second lifter 58 is arranged on the second mounting plate 56 and is connected to the second reference plate 57. The second driving member 59 is arranged on the second mounting plate 56 and is connected to the second lifter 58. The second driving member 59 drives the second lifter 58 to move, so that the second lifter 58 drives the second reference plate 57 to move up and down.

[0059] It should be noted that the sliding assembly 52 includes a sliding plate 521, a slider 522, and a slide rail 523. The slider 522 is installed at the bottom of the sliding plate 521. The slide rail 523 is installed on the second reference plate 57 and is slidably connected to the slider 522. The third telescopic moving assembly 53 and the material storage assembly 54 are installed on the sliding plate 521. The second driving member 59 adopts a servo motor. The second lifter 58 is mainly composed of a worm gear and a worm. The rotating shaft of the second driving member 59 is connected to the worm gear through a coupling. The worm is meshed with the worm gear. The rotating shaft of the second driving member 59 drives the worm gear to rotate. The worm gear drives the worm to move up and down, so as to drive the second reference plate 57 to move up and down to adjust the height of the second reference plate 57, and further facilitate the second reference plate 57 to reach the height of the iron shell motor 9 on the jacking device 2.

[0060] In a preferred embodiment, the assembly device 5 further includes a second guide rod 6 and a second guide sleeve 7. The second guide rod 6 is inserted and installed on the second mounting plate 56 and the second reference plate 57. The second guide sleeve 7 is installed on the second mounting plate 56. The second guide rod 6 is movably inserted into the second guide sleeve 7.

[0061] In this way, when the rotating shaft of the servo motor drives the worm gear to rotate, and the worm gear drives the worm to move up and down, thereby driving the second reference plate 57 to move up and down, the second guide rod 6 moves up and down in the second guide sleeve 7, preventing the second reference plate 57 from shifting in position during the up and down movement.
