Description

Technical field

[0001] The utility model relates to the technical field of motor production and assembly, in particular to an automatic feeding device for motor shrapnel. [Background Technology]

[0002] Micromotors are widely used electric drive devices, found in a wide range of electrical appliances and consumer products. However, with the continuous development of the economy, the production capacity and quality of micromotors have gradually become bottlenecks restricting the electrical industry. Traditional micromotor processing and production, particularly the assembly of elastic plates onto the motor's center pin, is primarily manual, resulting in low efficiency and failing to meet market demand.

[0003] For example, when assembling an elastic sheet onto the center pin of a motor, the sheet is a thin, tiny component. Currently, this is done manually using clamping tools such as tweezers, resulting in low assembly efficiency and high labor costs. Furthermore, the following issues also exist:

[0004] 1. If the force of the tweezers is too strong, the elastic sheet may be easily deformed, affecting the assembly quality;

[0005] 2. If the clamping force of the tweezers is too weak, the elastic sheet will easily separate from the tweezers and fall off, affecting the assembly effect.

[0006] Furthermore, before assembling the elastic sheet onto the motor's center pin, it needs to be inspected to determine if it is in good condition. However, current manual inspections are used to determine if the elastic sheet is in good condition, which is inefficient and labor-intensive.

[0007] For this reason, the present invention is studied and proposed in response to the above-mentioned problems. [Utility Model Content]

[0036] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0037] like Figure 1-9 As shown, the utility model is an automatic feeding device for motor shrapnel, comprising a frame 1, a motor shrapnel vibration disk 2 for storing motor shrapnel 120 is provided on the frame 1, a motor shrapnel temporary storage device 4 for temporarily storing the motor shrapnel 120 is provided on the frame 1 and located next to the motor shrapnel vibration disk 2, a motor shrapnel conveying mechanism 3 for conveying a single motor shrapnel 120 on the motor shrapnel vibration disk 2 to the motor shrapnel temporary storage device 4 for temporary storage is provided on the frame 1 and located between the motor shrapnel vibration disk 2 and the motor shrapnel temporary storage device 4, a motor shrapnel assembly mechanism 5 for assembling the motor shrapnel 120 on the motor shrapnel temporary storage device 4 on the center pin 110 of the motor housing 100 is provided on the frame 1 and located next to the motor shrapnel temporary storage device 4. When the utility model is working, the motor shrapnel conveying mechanism conveys a single motor shrapnel on the motor shrapnel vibration disk to the motor shrapnel temporary storage device for temporary storage and calibration, and then the motor shrapnel assembly mechanism assembles the motor shrapnel temporarily stored on the motor shrapnel temporary storage device onto the center pin of the motor housing. In order to realize the automatic supply, loading and assembly operations of the motor shrapnel by adopting the utility model, the utility model has the characteristics of high degree of automation and high working efficiency.

[0038] The utility model has the characteristic of high integration by integrating the motor shrapnel vibration plate, the motor shrapnel conveying mechanism and the motor shrapnel temporary storage device, namely the motor shrapnel assembly mechanism, into one frame.

[0039] The motor shrapnel vibration disk 2 in the present invention can be a flexible vibration disk, which plays a protective role and reduces the probability of the motor shrapnel being damaged by the motor shrapnel vibration disk 2 during storage.

[0040] like Figure 1-3As shown in Figures 5 and 6, in order to ensure efficient and stable transportation, the motor shrapnel transportation mechanism 3 includes a transportation mounting frame 31 provided on the frame 1, and a transportation sliding seat 33 that can slide along the X-axis direction of the frame 1 is provided on the transportation mounting frame 31, and a transportation sliding seat driving component 32 for driving the transportation sliding seat 33 to slide along the X-axis direction of the frame 1 is provided between the transportation sliding seat 33 and the transportation mounting frame 31; a transportation sliding plate 35 that can slide along the Y-axis direction of the frame 1 is provided on the transportation sliding seat 33, and a transportation sliding plate 35 for driving the transportation sliding plate 35 along the frame is provided between the transportation sliding plate 35 and the transportation sliding seat 33. A transport slide plate drive assembly 34 is provided, which slides along the Y-axis of the frame 1. A transport slide block 37 is mounted on the transport slide plate 35, which can slide along the Z-axis of the frame 1. A transport slide block drive assembly 36 is provided between the transport slide block 37 and the transport slide plate 35, for driving the transport slide block 37 to slide along the Z-axis of the frame 1. A hollow transport rod 38 is mounted on the transport slide block 37. The upper end of the transport rod 38 is provided with a transport rod external joint 39, which communicates with the inner cavity of the transport rod 38. The lower end of the transport rod 38 is provided with a plurality of transport suction holes 381, which communicate with the inner cavity of the transport rod 38. In this embodiment, the transport rod external joint 39 is used to communicate with an external air pipe. The transport slide drive assembly 32 includes, but is not limited to, a transport slide drive motor. The motor shaft of the transport slide drive motor is co-movably connected to a transport slide drive screw. The transport slide drive screw is slidably mounted with a transport slide nut that can be driven to slide by the transport slide drive screw. The transport slide nut is fixedly connected to the transport slide 33. The transport slide plate drive assembly 34 and the transport slide block drive assembly 36 can be rodless drive cylinders or slide table drive cylinders, etc. When the transport rod 38 adsorbs the motor shrapnel through the transport adsorption hole 381, the transport sliding block driving assembly 36 drives the transport sliding block 37 to drive the transport rod 38 to slide upward along the Z-axis direction of the frame, and then the transport sliding plate driving assembly 34 drives the transport sliding plate 35 to drive the transport rod 38 to slide along the Y-axis direction of the frame toward the side of the motor shrapnel temporary storage device 4, and then the transport sliding seat driving assembly 32 drives the transport sliding seat 33 to drive the transport rod 38 to slide along the X-axis direction of the frame toward the side of the motor shrapnel temporary storage device 4 until the transport rod 38 is located above the motor shrapnel temporary storage device 4, and finally the adsorption force on the motor shrapnel 120 is cancelled, so that the motor shrapnel 120 is temporarily stored in the motor shrapnel temporary storage device 4.

[0041] like Figure 5 、 6As shown, the lower portion of the transport rod 38 is sheathed with a deformable protective sleeve 382. When the transport rod attracts the motor spring through the transport adsorption hole, the attracted motor spring abuts against the lower end wall of the protective sleeve (or, in other words, the attracted motor spring is located inside the protective sleeve). This prevents the attracted motor spring from interfering with other motor springs and affecting the adsorption effect, ensuring secure and reliable adsorption. The protective sleeve 382 can be made of materials such as silicone or rubber.

[0042] like Figure 1-3 As shown in Figures 7, in order to ensure reliable temporary positioning, the motor shrapnel temporary storage device 4 includes a temporary storage mounting seat 41 provided on the frame 1, and the temporary storage mounting seat 41 is provided with a temporary storage positioning rod 42 for positioning the center hole sleeve of the motor shrapnel 120.

[0043] like Figure 7 As shown, the frame is provided with a temporary storage chassis, and the temporary storage mounting seat 41 is located inside the temporary storage chassis. During the process of the motor shrapnel assembly mechanism 5 adsorbing the motor shrapnel, the temporary storage chassis can effectively receive the motor shrapnel that is not firmly adsorbed and separated from the motor shrapnel assembly mechanism 5.

[0044] like Figure 1-3 As shown in Figures 7 and 8, the motor shrapnel assembly mechanism 5 includes an assembly mounting frame 51 provided on the frame 1. The assembly mounting frame 51 is provided with an assembly sliding plate 53 that can slide along the X-axis or Y-axis direction of the frame 1. An assembly sliding plate driving assembly 52 is provided between the assembly sliding plate 53 and the assembly mounting frame 51 for driving the assembly sliding plate 53 to slide along the X-axis or Y-axis direction of the frame 1. The assembly sliding plate 53 is provided with an assembly sliding block 55 that can slide along the Z-axis direction of the frame 1. An assembly sliding block driving assembly 54 is provided between the assembly sliding block 55 and the assembly sliding plate 53 for driving the assembly sliding block 55 to slide along the Z-axis direction of the frame 1. The assembly sliding block 55 is provided with a hollow assembly rod 56. The upper end of the assembly rod 56 is provided with an assembly rod external joint that communicates with the inner cavity of the assembly rod 56. The lower end of the assembly rod 56 is provided with a plurality of assembly adsorption holes 561 that communicate with the inner cavity of the assembly rod 56. In this embodiment, the assembly rod external joint 9 is used to communicate with an external air pipe. The assembly slide plate drive assembly 52 and the assembly slide block drive assembly 54 can be rodless drive cylinders or slide table drive cylinders. When the assembly rod 56 is attracted to the motor spring 120 through the assembly adsorption hole 561, the assembly slide block drive assembly 54 drives the assembly slide block 55 to drive the assembly rod 56 to slide upward along the Z-axis of the frame. Then, the assembly slide plate drive assembly 52 drives the assembly slide plate 53 to drive the assembly rod 56 to slide along the Y-axis of the frame to the corresponding workstation.

[0045] like Figure 7 、 8As shown, to precisely attract the motor spring, an assembly positioning mechanism 57 is provided between the lower end of the assembly rod 56 and the temporary storage mounting base 41. This assembly positioning mechanism 57 includes an assembly positioning hole provided at the lower end of the assembly rod 56 for positioning the temporary storage positioning rod 42. This effectively simplifies the structure, reduces manufacturing costs, and offers a rational design. Furthermore, the assembly positioning hole also serves to avoid interference with the temporary storage positioning rod 42, preventing it from interfering with normal operation.

[0046] like Figure 7 As shown, in order to ensure accurate assembly and positioning, a center needle clamping and positioning mechanism 6 is provided on the frame 1 and located on the side of the motor shrapnel assembly mechanism 5. The center needle clamping and positioning mechanism 6 is used to clamp and position the center needle 110 when the motor shrapnel assembly mechanism 5 assembles the motor shrapnel 120 on the center needle 110 of the motor housing 100. The center needle clamping and positioning mechanism 6 includes a clamping and positioning slider 62 provided on the frame 1 and slidable along the X-axis or Y-axis direction of the frame 1. A clamping and positioning slider driving assembly 61 is provided between the clamping and positioning slider 62 and the frame 1 for driving the clamping and positioning slider 62 to slide along the X-axis or Y-axis direction of the frame 1. A clamping claw cylinder 63 is provided on the clamping and positioning slider 62. The two driving ends of the clamping claw cylinder 63 are respectively provided with two clamping fingers 64 that can clamp toward each other or open back to back.

[0047] like Figure 1-3 As shown, in order to better detect the motor shrapnel and ensure the quality of the motor after assembly, a motor shrapnel detection mechanism 7 for detecting whether the motor shrapnel 120 is damaged is provided on the frame 1 and next to the motor shrapnel vibration plate 2. The motor shrapnel detection mechanism 7 can be a CCD detector or the like.
