Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of brushless motor parts processing equipment, specifically to a stator dust removal and testing integrated machine. Background Technology
[0002] Currently in the motor industry, dust, iron filings, and other foreign objects are generated during the incoming materials and assembly processes of motors. Often, these foreign objects cannot be removed after assembly, which can affect motor performance, such as causing excessive current, short circuits, or the motor failing to rotate. Improper handling of materials during assembly can also cause collisions, damaging the motor's magnets and resulting in breakage and cracks. These issues, once assembled into a finished product, will reduce the motor's lifespan and performance.
[0003] To address this, relevant technicians integrated a dust removal device and a crack detection mechanism into the motor assembly equipment. However, due to the obstruction of the magnetic tiles, the camera of the existing crack detection mechanism cannot detect the complete internal structure of the stator, resulting in some dust being left inside the stator or cracks existing in the part obstructed by the magnetic tiles. This makes the performance and lifespan of the motor after assembly less than ideal and needs to be improved. Utility Model Content
[0004] One of the technical problems to be solved by this application is to overcome the defects of the above-mentioned related technologies and provide a stator dust removal and testing integrated machine that can detect the complete internal structure of the stator.
[0005] The technical solution adopted by this utility model to solve the technical problem is as follows: a stator dust removal and inspection integrated machine, including a turntable and its rotary driver, stator positioning seats evenly distributed on each station on the turntable, and a feeding mechanism, a first dust removal mechanism, a first vision inspection mechanism and a unloading mechanism respectively provided on the outer side of each station on the turntable, the rotary driver, the feeding mechanism, the first dust removal mechanism, the first vision inspection mechanism and the unloading mechanism are electrically connected to the controller; the first vision inspection mechanism includes a vision probe, a probe rod and a lifting drive assembly, the vision probe is installed on the top of the probe rod, the probe rod is connected to the lifting drive assembly, the lifting drive assembly is used to lift the probe rod to make the vision probe penetrate into the stator or to lower the probe rod to make the vision probe return to the bottom of the turntable.
[0006] Compared with related technologies, this utility model has the following advantages: The first vision inspection mechanism is equipped with a probe and a lifting drive assembly. The lifting drive assembly raises the probe to allow the vision probe to penetrate deep into the stator, enabling multi-position detection and identification of whether there is dust or cracks in the overall internal structure of the stator. This avoids the situation where parts are missed due to being blocked by the magnetic tiles during single-position detection, and all defective stators are screened out, thereby improving the yield of motor production. The lifting drive assembly lowers the probe to return the vision probe to the bottom of the turntable, which avoids the probe and vision probe from obstructing the rotation of the turntable.
[0007] Preferably, the first dust removal mechanism includes a rotating air head, an air rod, and a vertical displacement assembly. The rotating air head is rotatably connected to the air rod, and the air rod is connected to the vertical displacement assembly. The vertical displacement assembly is used to move the air rod upward so that the rotating air head penetrates deeper into the stator, or to move the air rod downward so that the rotating air head returns to below the turntable. This allows the rotating air head to penetrate deep into the stator, thereby forming a top-down airflow inside the stator, blowing dust or foreign objects out of the stator for more comprehensive dust removal and better reducing the probability of dust or foreign objects remaining inside the stator.
[0008] As an improvement, the turntable is further equipped with a second dust removal station and a second visual inspection station. The outer side of the second dust removal station is equipped with a second dust removal mechanism with the same structure as the first dust removal mechanism, and the outer side of the second visual inspection station is equipped with a second visual inspection mechanism with the same structure as the first visual inspection mechanism. The second dust removal mechanism and the second visual inspection mechanism are electrically connected to the controller. This secondary dust removal and secondary identification further improves the dust removal effect and reduces crack recognition errors.
[0009] As an improvement, a pressing mechanism is provided above both the first and second dust removal stations. This pressing mechanism is electrically connected to the controller and is used to press down on the top of the stator before dust removal and to detach it after dust removal. It is also possible that when the pressing mechanism presses down on the top of the stator, it will shake out any foreign objects inside the stator.
[0010] As an improvement, dust collection components are installed below both the first and second dust removal stations on the turntable. These dust collection components contain elastic pads, through which the self-rotating air blower passes. This collects dust and foreign objects, preventing them from affecting the operation of the stator dust removal and inspection integrated machine.
[0011] Preferably, both the lifting drive assembly and the vertical displacement assembly consist of a servo motor, a lead screw, a lead screw nut, and an L-shaped slide rail bracket that are connected in a transmission relationship. The L-shaped slide rail bracket is fixedly connected to the frame. The servo motor provides precise stroke control, and the rotation of the lead screw and lead screw nut is smooth, resulting in stable airflow in the dust removal mechanism and low noise in the image recognition of the vision inspection mechanism.
[0012] Preferably, each workstation is equipped with a material detection sensor on its inner side, and the material detection sensor is electrically connected to the controller.
[0013] As an improvement, the feeding mechanism includes a first feeding assembly, a clamping cylinder, a 180-degree tilting cylinder, a second feeding assembly, and a feeding displacement drive assembly. Both the first and second feeding assemblies consist of a vertically connected moving cylinder and a clamping cylinder. The clamping cylinder is mounted on the rotating shaft of the 180-degree tilting cylinder. The first feeding assembly is used to clamp the inverted stator and place it between the clamping jaws of the clamping cylinder. The clamping cylinder is used to clamp the stator. The 180-degree tilting cylinder is used to drive the clamping cylinder to rotate 180 degrees. The second feeding assembly is used to clamp the stator rotated 180 degrees from the clamping cylinder and place it into the stator positioning seat at the turntable feeding station. The feeding displacement drive assembly is used to drive the first and second feeding assemblies to move synchronously. A protrusion at the bottom of the stator is also included.
[0014] Preferably, a defective product sorting mechanism is also included, which is fixed on the frame and installed next to the unloading mechanism. This mechanism is used to collect defective stators.
[0015] Preferably, the defective product sorting mechanism includes two parallel defective product tracks and a sorting cylinder disposed between the tracks. The defective product tracks extend to the side of the frame. The head of the push rod of the sorting cylinder is provided with a lever, which extends to both sides onto the defective product tracks. Both ends of the lever are provided with gathering blocks. The sorting cylinder is electrically connected to a controller and is used to gather the defective stators placed at the head of a certain defective product track by the feeding mechanism into that track. The number of defective stators is relatively small, and a suitable accumulation can reduce the number of times workers need to retrieve them. Attached Figure Description

[0024] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0026] This implementation example Figures 1 to 3 The diagram shows an integrated stator dust removal and inspection machine, comprising a frame 1 and a controller 2. The frame 1 is equipped with a turntable 3 and its rotation driver 4. The turntable 3 has stator positioning seats 5 evenly distributed around its circumference at various workstations. Each workstation on the turntable 3 has a feeding mechanism 10, a first dust removal mechanism 20, a first visual inspection mechanism 30, and a discharging mechanism 60 respectively located on its outer side. The feeding mechanism 10, the first dust removal mechanism 20, the first visual inspection mechanism 30, and the discharging mechanism 60 are electrically connected to the controller 2. The first visual inspection mechanism 30... Figure 5 The device includes a vision probe 31, a probe rod 32, and a lifting drive assembly 33. The vision probe 31 is mounted on top of the probe rod 32. The lifting drive assembly 33 is used to raise the probe rod 32 to allow the probe to penetrate deeper into the stator or to lower the probe rod 32 to allow the vision probe 31 to return to the turntable 3. The vision probe 31 and the lifting drive assembly 33 are electrically connected to the controller 2. A multi-position AI recognition method is used to detect the internal structure of the stator after dust removal. If there are foreign objects, broken magnets, cracks, etc., such defective stators will be sorted out.
[0027] Among them, the first dust removal mechanism 20 is as follows Figure 4 The device includes a self-rotating air blower head 21, an air rod 22, and a vertical displacement assembly 23. The self-rotating air blower head 21 is rotatably connected to the air rod 22, and the vertical displacement assembly 23 is electrically connected to the controller 2. The assembly is used to move the air rod 22 upwards so that the self-rotating air blower head 21 penetrates deeper into the stator, or to move the air rod 22 downwards so that the self-rotating air blower head 21 returns to below the turntable 3. The top of the self-rotating air blower head 21 has two or three evenly distributed, downward-sloping air outlets, enabling it to rotate and generate a 360-degree airflow. During the downward movement of the vertical displacement assembly 23, a downward airflow is generated, achieving a stable, all-around dust removal effect on the stator.
[0028] In this embodiment, as Figure 4 and 5As shown, the lifting drive assembly 33 and the vertical displacement assembly 23 both consist of a servo motor, a lead screw, a lead screw nut, and an L-shaped slide rail bracket that are in transmission cooperation. The L-shaped slide rail bracket is fixedly connected to the frame 1, and the servo motor is electrically connected to the controller 2. Here, the shape of the lead screw nut has been adjusted. A slider that is slidably connected to the L-shaped slide rail bracket is fixed to the side of the lead screw nut. A connecting plate extending downwards from the stator positioning seat is connected to the bottom of the lead screw nut. The pneumatic rod 22 and the probe rod 32 are mounted on the connecting plate. Both the pneumatic rod 22 and the probe rod 32 are hollow. The bottom of the pneumatic rod 22 is connected to the air source, and the middle of the probe rod 32 is used to arrange data cables.
[0029] As an improvement, the turntable 3 is further provided with a second dust removal station and a second visual inspection station. A second dust removal mechanism 40 with the same structure as the first dust removal mechanism 20 is located outside the second dust removal station. A second visual inspection mechanism 50 with the same structure as the first visual inspection mechanism 30 is located outside the second visual inspection station. The second dust removal mechanism 40 and the second visual inspection mechanism 50 are electrically connected to the controller 2, respectively. This is used for secondary dust removal and re-inspection.
[0030] As an improvement, the feeding mechanism 10 includes a first feeding component, a clamping cylinder, a 180-degree tilting cylinder, a second feeding component, and a feeding displacement drive component. The first feeding component, clamping cylinder, 180-degree tilting cylinder, second feeding component, and feeding displacement drive component are all electrically connected to the controller 2. Both the first and second feeding components consist of a vertically connected moving cylinder and a clamping cylinder. The clamping cylinder is mounted on the rotating shaft of the 180-degree tilting cylinder. The first feeding component is used to clamp the inverted stator and place it between the clamping jaws of the clamping cylinder. The clamping cylinder is used to clamp the stator. The 180-degree tilting cylinder is used to drive the clamping cylinder to rotate 180 degrees. The second feeding component is used to clamp the stator rotated 180 degrees from the clamping cylinder and place it into the stator positioning seat 5 of the turntable 3. The feeding displacement drive component is used to drive the first and second feeding components to move synchronously.
[0031] As an improvement, a dust removal station and a dust removal station with the following features are installed below the first and second dust removal stations of turntable 3: Figure 6 The dust collection component 70 shown has an elastic pad 72 inside the dust collection hopper 71. The self-rotating air blowing head 21 passes through the elastic pad 72, and the two dust collection columns 73 below the dust collection hopper 71 are fixed on the frame 1.
[0032] As an improvement, a [feature] is installed above both the first and second dust removal stations. Figure 7The pressing mechanism 80 shown is electrically connected to the controller 2. The pressing mechanism 80 is used to press the top of the stator before dust removal and to detach the top of the stator after dust removal. This prevents the dust removal airflow from blowing the stator up, as a fall after being blown up could cause a collision and potentially damage the magnets. The pressing mechanism 80 includes a pressing cylinder 81, with a rubber head 82 at the bottom of the push rod. The pressing cylinder 81 is mounted above the stator positioning seat 5 at the dust removal station via a pressing bracket 83. The pressing bracket 83 is fixed to the carrier plate inside the turntable 3 in a "Z" shape.
[0033] As an improvement, each workstation is equipped with a material detection sensor 6 on its inner side, and the material detection sensor 6 is electrically connected to the controller 2. The material detection sensor 6 is mounted on the carrier plate inside the turntable 3 via a stand.
[0034] As improvements, it also includes, for example Figure 8 The defective product sorting mechanism 90 shown has a sorting frame (not shown) fixed on the frame 1 and installed next to the unloading mechanism 60. The defective product sorting mechanism 90 includes two parallel defective product tracks 91 mounted on the sorting frame and a sorting cylinder 92 positioned between the defective product tracks 91. Each defective product track 91 includes a base plate and a U-shaped frame. The defective product track 91 extends to the side of the frame 1, allowing workers to remove defective stators from the U-shaped frame without affecting the normal operation of the integrated machine. A lever 93 is fixed to the connecting block (not shown) at the head of the push rod of the sorting cylinder 92. A sliding guide assembly (not shown) is provided between the connecting block and the sorting frame. The lever 93 extends to both sides onto the defective product tracks 91, and both ends of the lever 93 are equipped with gathering blocks 94. The sorting cylinder 92 is electrically connected to the controller 2 and is used to gather the defective stators placed at the head of a certain defective product track 91 by the unloading mechanism 60 into the U-shaped frame at the tail of that defective product track 91.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
