Description

Technical Field

[0001] The invention relates to the technical field of brushless motor parts processing equipment, in particular to a stator dust removal and detection integrated machine. Background Art

[0002] Currently, in the motor industry, dust, iron filings, and other foreign matter are generated during the incoming materials and assembly processes. Often, these foreign matter cannot be removed after assembly is complete, which can affect motor performance, causing problems such as excessive current, short circuits, and motor malfunction. Improper handling of materials during assembly can also cause collisions, damaging the motor's magnetic tiles, resulting in breakage and cracks. This can shorten the motor's lifespan and performance after assembly. Therefore, dust removal and crack identification are necessary after magnetic tile assembly.

[0003] The stator output after the magnetic tile assembly process has its opening facing upward, while the dust removal operation requires the opening to be set downward facing upward, so a reversing operation is required; and the visual camera in the common crack recognition device is fixedly set, which will cause the part blocked by the magnetic tile to be missed when used in the internal structure inspection of the stator, which may easily lead to dust being left there, or cracks existing there without being discovered, resulting in the performance and life of the motor after it is assembled into a finished product being less than ideal. It is urgent to develop a stator dust removal and detection all-in-one machine that can be integrated into the motor assembly equipment. Summary of the Invention

[0004] A technical problem to be solved by the present application is to overcome the defects of the above-mentioned related technologies and provide a stator dust removal and detection integrated machine that can detect the complete internal structure of the stator after reversing and dust removal.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a stator dust removal and detection integrated machine, including a turntable and its rotary drive, the turntable is provided with stator positioning seats evenly distributed on each station, the outer side of each station of the turntable is respectively provided with a loading mechanism, a first dust removal mechanism, a first visual detection mechanism and a unloading mechanism, the rotary drive, the loading mechanism, the first dust removal mechanism, the first visual detection mechanism and the unloading mechanism are respectively electrically connected to the controller,

[0006] The feeding mechanism includes a reversing assembly, which is used to flip the stator with the opening facing upward 180 degrees to turn the stator with the opening facing downward. The feeding mechanism is used to clamp the stator with the opening facing upward and place the stator with the opening facing downward after the reversal into the stator positioning seat of the feeding station;

[0007] The first dust removal mechanism includes an air blowing head, an air rod, and an up-and-down displacement assembly, wherein the air blowing head is rotatably connected to the air rod, and the up-and-down displacement assembly is used to move the air rod upward so that the air blowing head passes through the stator positioning seat of the first dust removal station and penetrates into the top of the stator, or to move the air rod downward so that the air blowing head returns to the bottom of the turntable. The air blowing head is used to blow air 360 degrees and forms a downward airflow at the top of the stator during the process of the up-and-down displacement assembly moving the air rod downward;

[0008] The first visual inspection mechanism includes a visual probe, a probe rod and a lifting drive assembly. The visual probe is installed on the top of the probe rod. The lifting drive assembly is used to lift the probe rod so that the visual probe passes through the stator positioning seat of the first visual inspection station and penetrates into the stator, or to lower the probe rod so that the visual probe returns to under the turntable. The visual probe is used to detect the internal structure of the stator at multiple positions.

[0009] Compared with the related art, the present invention has the following advantages: a reversing component is added to the feeding mechanism to complete the automatic reversing operation, so that the stator dust removal and detection integrated machine can be connected behind the magnetic tile assembly device to be integrated into the motor automatic assembly equipment; and the 360-degree air blowing head of the first dust removal mechanism can form a downward airflow at the top of the stator during the process of its up and down displacement component moving the air rod downward, taking away the dust and foreign matter in the stator, and achieving the effect of all-round and stable dust removal of the stator; the first visual inspection mechanism is added with a probe rod and a lifting drive component, and the probe rod is lifted by the lifting drive component to make the visual probe penetrate into the stator, so that the visual probe can detect the overall internal structure of the stator at multiple positions, avoiding the situation where the undetected part is missed due to being blocked by the magnetic tile, and all defective stators are screened out, thereby improving the yield of the motor finished product; and the up and down displacement component and the lifting drive component respectively make the blowing head and the air rod and the probe rod and the visual probe return to the bottom of the turntable to avoid interfering with the rotation of the turntable.

[0010] As an improvement, a first pressing mechanism is provided above the first dust removal station. This mechanism is electrically connected to the controller and is used to press the top of the stator before dust removal and to detach from the top of the stator after dust removal. This prevents excessive airflow from the air blower, which could cause the stator to be lifted off the stator retaining seat in the first dust removal station and then fall and damage the magnetic tiles. It also prevents dust and foreign matter from being shaken off the stator when the pressing mechanism strikes the top of the stator.

[0011] Preferably, the first pressing mechanism includes a pressing motor, a pressing head and a pressing bracket. The pressing motor is fixed to the pressing bracket and is arranged above the first dust removal station.

The stroke control of the servo motor is relatively precise, the rotation coordination of the screw and the screw nut is smooth, and the lifting position speed is stable, so that the airflow of the dust removal mechanism is stable, and the position of the visual probe relative to the stator in the positioning detection of the visual detection mechanism is not easy to change.

[0014] As an improvement, dust collectors are installed below the first and second dust removal stations of the turntable. These collectors are equipped with elastic pads through which the air blower passes. This collects dust and foreign matter, preventing them from affecting the operation of the stator dust removal and detection integrated machine.

[0015] Preferably, a material detection sensor is provided inside each workstation, and the material detection sensor is electrically connected to the controller. The material detection sensor is used to detect whether a stator is present in the stator positioning seat of the corresponding workstation, thereby reducing idle operations and saving energy.

[0017] As an improvement, a defective product sorting mechanism is also included, which is fixed to the frame and installed next to the unloading mechanism. It is used to collect defective stators. The number of defective stators is small, and an appropriate amount is accumulated to reduce the number of workers' recycling times.

[0018] Preferably, the defective product sorting mechanism includes two defective product rails arranged side by side and a sorting cylinder arranged between the defective product rails, the defective product rails extend to the side of the frame, and the head of the sorting cylinder push rod is provided with a shifting rod, and the shifting rod extends to both sides onto the defective product rails, and both ends of the shifting rod are provided with a gathering block; the sorting cylinder is electrically connected to the controller, and is used to shift the defective stator placed by the unloading mechanism at the head of a defective product rail into the defective rail.
