Description

Technical Field

[0001] This utility model relates to the field of motor assembly equipment technology, and in particular to an automatic assembly equipment for a motor flat square shaft and snap ring. Background Technology

[0002] The white goods manufacturing industry is generally labor-intensive and involves high labor intensity. As the "engine" of white goods, the metal-cased motor requires the assembly of many different types and quantities of components, involving complex processes. The assembly of the motor's flat square shaft and E-type retaining ring, in particular, demands high skill and is very difficult.

[0003] The assembly of the motor flat square shaft and the E-type snap ring requires very strict positioning accuracy and reliability. Otherwise, it is easy to cause the axial fixation of the motor terminal to loosen and fail, resulting in insufficient torque transmission, abnormal noise and vibration during operation, greatly reduced service life, and poor end-user experience.

[0004] Previously, workers would unpack the pre-packaged E-type retaining rings, place them individually into a transfer box, and transport them to the production line. Then, they would manually pick out the individual E-type retaining rings, fix them on a hand-held installation tool, and simultaneously pick up the motor, fixing the motor shaft while visually locating the retaining ring slot and flat side. The E-type retaining ring would then be installed in the retaining ring slot on the motor shaft, ensuring the E-type retaining ring tongue was on the opposite side of the flat side. To ensure assembly position and accuracy, the E-type retaining rings needed to be individually cut and fixed to the tool. Because the retaining rings are made of elastic material, this process was prone to errors in force control, causing the retaining rings to spring away, wasting materials and labor. Furthermore, manual assembly, requiring both hand and eye work, easily led to fatigue, resulting in substandard E-type retaining ring tongue position and accuracy, and extremely low production efficiency. The entire process was entirely manual, with manual quality inspection, leading to errors and omissions. These errors were detected at the end equipment and resulted in complaints from end users. However, the subsequent disassembly and repair after processing caused significant cost waste and negatively impacted the product's brand image.

[0005] The entire process involves manual handling, which is time-consuming, labor-intensive, and requires a large workforce, resulting in low production efficiency. Furthermore, the entirely manual operation of the entire process can easily lead to quality defects. To address these shortcomings, manufacturers of metal-cased motors for white goods are actively seeking automated assembly and inspection solutions for the "assembly of the flat square shaft and E-type retaining ring in a metal-cased motor" process.

[0006] Therefore, it is necessary to provide an automatic assembly device for motor flat square shafts and snap rings to solve the above problems. Utility Model Content

The clamping and flipping device 3 moves away from the assembly device 5 to its original position to complete the reset. The lifting device 2 moves downward to its original position and then resets. During the descent, the lifting device 2 places the iron-shell motor 9 on the feeding line 1, which is then transported to the next station by the feeding line.

It should be noted that in this embodiment, the first telescopic moving member 31 is a telescopic cylinder, and the rotating moving member 32 is a rotary cylinder.

[0045] Thus, when the first telescopic moving member 31 drives the rotating moving member 32 and the gripper 33 to move towards the assembly device 5, the gripper 33 clamps the iron-shell motor 9, and the rotating moving member 32 drives the iron-shell motor 9 on the gripper 33 to rotate 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, the rotating motion member 32 is rotatably mounted on the support block 351, the first lifter 36 is disposed on the first mounting plate 34 and connected to the first reference plate 35, the first driving member 37 is disposed 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 drive component 37 is a servo motor, and the first lifting device 36 is mainly composed of a worm gear and a worm. The rotating shaft of the first drive component 37 is connected to the worm gear through a coupling. The worm and the worm gear mesh. The rotating shaft of the first drive component 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, so that the first reference plate 35 can reach the same height as the iron-shell motor 9 on the lifting 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] Thus, when the shaft of the first driving component 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 within the first guide sleeve 39 to prevent the first reference plate 35 from shifting its position during the lifting and lowering process.

[0050] Please refer to the following: Figures 4 to 9 In a preferred embodiment, the positioning device 4 includes a power component 41, a moving component 42, and a positioning component 43.

The ball screw pair mainly consists of a screw and a nut installed on the screw. A gear is installed on the nut. The screw is connected to the positioning component 43. The power component 41 drives the nut to rotate by being mounted on the gear via a belt. The nut drives the screw to move up and down, thereby driving the positioning component 43 to move up and down.

[0052] In a preferred embodiment, the positioning component 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 component 42, the flat square shaft clamping assembly 432 is mounted on the mounting bracket 431, and the first sensor 433 is mounted on the bottom of the mounting bracket 431.

[0053] It should be noted that, in this embodiment, the flat square shaft clamping assembly 432 mainly consists 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 via a belt, the servo motor 4321 continues to drive the three-jaw chuck to rotate, thereby changing the orientation of the assembly position of the flat square shaft 91 with the E-type retaining ring 8; or the servo motor 4321 drives the three-jaw chuck 4322 to release the flat square shaft 91.

[0054] When the moving component 42 drives the mounting bracket 431 of the positioning component 43 to descend 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 as the mounting bracket 431 descends. At this time, the flat square shaft clamping assembly 432 starts to clamp the flat square shaft 91 on the iron-shell motor 9. 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 flat square shaft 91 of the iron-shell motor 9 with the E-type retaining ring 8, so that the direction of the assembly position on the flat square shaft 91 of the iron-shell motor 9 is opposite to the assembly device 5, so as to facilitate the assembly of the E-type retaining ring 8 on the assembly position of the flat square shaft 91.

[0055] In a preferred embodiment, the positioning component 43 further includes a square shaft locking assembly 44 and a second sensor 45. The square shaft locking assembly 44 is mounted on the mounting bracket 431, and the second sensor 45 is mounted on the square shaft locking assembly 44.

One end of the retaining piece 442 has a slot 443, and the second sensor 45 is mounted on the retaining piece 442.

[0056] When the servo motor of the flat shaft clamping assembly 432 drives the three-jaw chuck to rotate, changing the direction of the assembly position of the flat shaft 91 and the E-type retaining ring 8, so that the direction of the assembly position on the flat shaft 91 is opposite to the assembly device 5, the pneumatic component 441 of the flat shaft assembly drives the clamping piece 442 to move, so that the jaw 443 of the clamping piece 442 clamps the flat shaft 91 of the iron shell motor 9, thereby locking the flat shaft 91 of the iron shell motor 9. After the second sensor 45 detects that the flat shaft 91 is locked, the assembly transposition assembles the E-type retaining ring 8 onto the flat 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 storage assembly 54. The second telescopic moving member 51 is connected to the sliding assembly 52, the third telescopic moving assembly 53 is mounted on the sliding assembly 52, and the storage assembly 54 is mounted on the sliding assembly 52. ​​The second telescopic moving member 51 is connected to the storage assembly 54 via a connecting rod 55.

The second mounting plate 56 is spaced below the second reference plate 57. The second telescopic motion member 51 and the sliding assembly 52 are mounted on the second reference plate 57.

The second lifter 58 is disposed on the second mounting plate 56 and connected to the second reference plate 57. The second drive member 59 is disposed on the second mounting plate 56 and connected to the second lifter 58.

[0059] It should be noted that the sliding component 52 includes a sliding plate 521, a slider 522, and a slide rail 523.

The third telescopic motion component 53 and the storage component 54 are installed on the sliding plate 521. The second driving component 59 adopts a servo motor, and the second lifting device 58 is mainly composed of a worm gear and a worm. The rotating shaft of the second driving component 59 is connected to the worm gear through a coupling. The worm and the worm gear mesh. The rotating shaft of the second driving component 59 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 to adjust the height of the second reference plate 57, so that the second reference plate 57 can reach the same height as the iron-shell motor 9 on the lifting 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, and the second guide rod 6 is movably inserted into the second guide sleeve 7.

[0061] Thus, when the servo motor shaft 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 within the second guide sleeve 7 to prevent the second reference plate 57 from shifting its position during the lifting and lowering process.
