Description

Technical Field

[0001] This invention relates to the field of motor manufacturing and assembly tools, specifically to an automatic material dispensing device for motor magnet rings. Background Technology

[0002] The permanent magnets inside the motor are in direct contact with the motor housing. However, because the housing is relatively thin, a protective magnet ring is added to prevent severe magnetic leakage. The main function of the protective magnet ring is to prevent magnetic leakage in the motor and extend its service life.

[0003] In the current production process, the magnetic rings are mainly placed onto the conveyor belt manually. Due to the structural characteristics of the products, the materials tend to become tangled and difficult to disperse when piled up, making automatic material distribution difficult. Traditional manual identification and loading is costly, and operators are prone to placing the materials in the wrong direction, stacking them incorrectly, and causing subsequent loading mechanisms to jam. Furthermore, when assembling the motor and the magnetic rings, the installation angle of the magnetic rings may not correspond to the motor, requiring additional manual adjustment.

[0004] To avoid inaccurate installation of the magnet ring during motor assembly, utility model patent CN210201662U discloses a motor magnet ring installation fixture. This fixture includes a worktable, a control switch, a fixing component, and an installation component. The middle of the worktable is fixedly connected to the fixing component, and the installation component is positioned above the fixing component. The installation component is fixed to the worktable surface by a support column. The control switch is fixedly connected to the worktable and electrically connected to the installation component. The fixing component includes a sleeve, a telescopic rod, and a return spring. The side wall of the telescopic rod has a vertically oriented positioning groove, and the top of the telescopic rod has a positioning pin. In this patent, during use, the magnet ring is first fitted onto the outside of the telescopic rod through the positioning groove. Then, the motor is placed above the telescopic rod through the positioning groove at the top. The operator then presses the synchronous switches located on both sides of the fixing component, causing the piston rod to descend and rivet the motor into the magnet ring under the drive of a hydraulic cylinder. While this patent can improve the positioning accuracy of the magnet ring during motor assembly, it cannot solve problems such as multiple magnet rings overlapping during material feeding and mismatch between the installation angle and requirements. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an automatic material feeding device for motor magnet rings, which can realize automatic material feeding and reduce the cost of manual material feeding.

[0017] In this invention, as an optional embodiment, the conveying mechanism further includes a second distributor, which is installed on the conveyor belt.

[0018] In this invention, as an optional embodiment, the second distributor includes a first jet assembly, a mounting bracket, and a sensing assembly. The mounting bracket is connected to the conveyor belt. The first jet assembly includes a first jet pipe and a first air valve. Both the first jet pipe and the sensing assembly are mounted on the mounting bracket. Both the first air valve and the sensing assembly are connected to the power control mechanism. The first jet pipe is connected to an external air source. The sensing assembly is used to detect the length of the magnetic protective ring and send a detection signal to the power control mechanism. The power control mechanism is used to control the opening and closing of the first air valve according to the detection signal.

[0019] In this invention, as an optional embodiment, the second distributor further includes a pushing assembly, which includes a push-pull rod, a push-pull motor, and a pushing plate.

The second air valve and the infrared beam sensor are both connected to an electric control mechanism. The limiting plate is connected to the conveyor belt and is installed behind the first distributor. The limiting plate is used to limit the outer diameter of the magnetic ring passing through the limiting plate, so that the magnetic ring within the limited outer diameter range can pass through. The infrared beam sensor is used to send an obstruction signal to the electric control mechanism when it detects a magnetic ring standing in front of the limiting plate, so that the electric control mechanism controls the second jet pipe to work.

[0024] In this invention, as an optional embodiment, the conveying mechanism further includes a directional filter, one side of which is connected to a baffle plate, and the front end of the directional filter forms a beveled notch facing the end direction.

Detailed Implementation

[0038] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Unless otherwise specified, the materials and equipment used in this embodiment are commercially available. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a connection through an intermediary, or a connection within two elements or an interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0042] This application provides an automatic material sorting device for motor magnet rings, including a base, a feeding mechanism, a conveying mechanism, and a power control mechanism. Under the control of the power control mechanism, the feeding mechanism transports the magnet rings to the conveying mechanism, and the conveying mechanism transmits them. A first sorter set on the conveying mechanism can restrict the passage of only magnet rings placed horizontally on the conveyor belt, which can prevent multiple stacked magnet rings and vertically placed magnet rings from being transported to the motor assembly station, thereby avoiding trouble for the assembly of motor magnet rings.

[0043] Please refer to Figures 1 to 10 As shown in the figure, this embodiment provides an automatic dispensing device for motor magnet rings, including a base 1, a feeding mechanism 2, a conveying mechanism 3, and a power control mechanism 4. The base 1 serves as a support and can accommodate electrical components, such as a first drive mechanism 11 housed within it, while the power drive mechanism 4 is also mounted on the base 1. The feeding mechanism 2 is also mounted on the base 1, and the power drive mechanism 4 can be mounted on its back. Support members for the base 1 can also be installed at the bottom of the base 1, typically at the four corners.

[0044] The feeding mechanism 2 of this embodiment includes a hopper 21 and a feeding assembly 22. The feeding assembly 22 is mounted on the hopper 21 and connected to the first drive mechanism 11. The feeding assembly 22 is used to transport the protective magnetic rings 5 ​​in the hopper 21 upward under the drive of the first drive mechanism 11. The first drive mechanism 11 typically includes a motor and a drive shaft. The drive shaft is connected to the motor, which is connected to a power control mechanism. The drive shaft is also connected to the feeding assembly 22, so the power control mechanism 4 controls the motor to work, the motor drives the drive shaft to rotate, and thus drives the feeding assembly 22 to move. Specifically, since the feeding assembly 22 needs to transport the protective magnetic rings 5 ​​in the hopper 21 upward, the feeding assembly 22 moves upward under the drive of the drive shaft. The hopper 21 is used to store a relatively large number of protective magnetic rings 5. Since the feeding assembly 22 transports the protective magnetic rings 5 ​​upward, it can be understood that the hopper 21 is installed at a relatively low position.

[0045] The conveying mechanism 3 includes a second drive mechanism 31, a conveyor belt 32, a baffle plate 33, and a first distributor 34. The conveyor belt 32 is connected to the second drive mechanism 31, and the inner side of the conveyor belt 32 is connected to the feeding mechanism 2. The baffle plate 33 is vertically disposed on the outer side of the conveyor belt 32, and the first distributor 34 is mounted on the baffle plate 33. The conveyor belt 32 is installed horizontally and operates under the drive of the second drive mechanism 31, transporting the magnetic protective rings 5 ​​on the conveyor belt 32 to their destination. The inner side of the conveyor belt 32 receives the magnetic protective rings 5 ​​transported from the feeding mechanism 2, and the outer baffle plate 33 prevents the magnetic protective rings 5 ​​from falling during transport.

[0046] Combination Figure 5The installation height of the first distributor 34 is higher than the diameter of a single magnetic ring 5 but smaller than its height, ensuring that only the bottom layer of magnetic rings 5 ​​on the conveyor belt 32 can pass through at a time. The purpose of the first distributor 34 is primarily to prevent two or more magnetic rings 5 ​​from passing through when stacked on the conveyor belt 32, and to prevent vertically placed magnetic rings 5 ​​from passing through. The first distributor 34 is installed at a certain height, allowing inverted magnetic rings 5 ​​to pass through. If two magnetic rings 5 ​​are twisted together, that is, overlapped and embedded, they can still pass through the first distributor 34 because their height does not exceed the height of the first distributor 34, as they are not stacked. The first distributor 34 includes a connector 341 and a distributor plate 342. The connector 341 is mounted on a baffle plate, and the distributor plate 342 is connected to the connector 341. The distributor plate 342 is located above the conveyor belt 32. The installation height of the distributor plate 342 is greater than the diameter of the magnetic ring 5 and less than the height of the magnetic ring 5.

[0047] The material distribution plate 342 is triangular in shape. The hypotenuse of the triangular material distribution plate 342 extends from the inside to the outside in the direction of conveyor belt 32. Therefore, when the magnetic ring 5 is transported by the conveyor belt 32, the magnetic ring 5 that exceeds the height is gradually blocked by the triangular baffle and falls off, thus realizing material distribution.

[0048] In this embodiment, the power control mechanism 4 is mounted on the base 1 and is electrically connected to the first drive mechanism 11 and the second drive mechanism 31. The power control mechanism 4 may include control components such as control circuits.

[0049] In a preferred embodiment, the conveyor belt 32 is inclined. Specifically, the conveyor belt 32 is inclined downwards toward the baffle plate 33. That is, the conveyor belt 32 is inclined from the inside to the outside, so that when the magnetic ring 5 is conveyed to the conveyor belt 32 by the feeding mechanism 2, the inclined structural design can prevent the magnetic ring 5 from falling off, ensuring that the magnetic ring 5 can be transported normally on the conveyor belt 32.

[0050] In this embodiment, the hopper 21 specifically includes a first loading platform 211 and a hopper 212. The hopper 212 is used to store a relatively large amount of magnetic protective rings 5. When the first loading platform 211 is stationary and not in operation, its top surface is close to, flush with, slightly higher than, or slightly lower than the bottom surface of the hopper 212. When the first loading platform 211 is in operation, it will move up and down. Combined with the feeding assembly 22, which includes a second feeding platform 221 and a second storage platform 222, both the first feeding platform 211 and the second feeding platform 221 are connected to the first driving mechanism 11. The installation height of the second feeding platform 221 and the second storage platform 222 is higher than that of the first feeding platform 211. The second storage platform 222 is located between the first feeding platform 211 and the second feeding platform 221. The first feeding platform 211 is used to move in the height direction under the drive of the first driving mechanism 11 to transport the magnetic ring 5 in the hopper 212 to the second storage platform 222. The second feeding platform 221 is used to move in the height direction under the drive of the first driving mechanism 11 to transport the magnetic ring 5 in the second storage platform 222 to the conveyor belt 32. Typically, the first drive mechanism 11 simultaneously drives the first loading platform 211 and the second loading platform 221. Therefore, the first loading platform 211 and the second loading platform 221 move upwards or downwards simultaneously. When moving upwards, the first loading platform 211 transports the magnetic protective ring 5 to the second loading platform 221 and the second storage platform 222. The second loading platform 221 then transports the magnetic protective ring 5 from the second storage platform 222 or from the second loading platform 221 upwards to the conveyor belt 32. The first loading platform 211 moves up and down along the side wall of the second storage platform 222.

[0051] Furthermore, the feeding assembly 22 also includes a third feeding platform 223 and a third storage platform 224. The third feeding platform 223 is connected to the first drive mechanism 11. The installation height of both the third feeding platform 223 and the third storage platform 224 is higher than that of the second feeding platform 221 and the second storage platform 222. The third storage platform 224 is located between the third feeding platform 223 and the second feeding platform 221. The third storage platform 224 is used to store the magnetic protective ring 5 from the second feeding platform 221. The third feeding platform 223 is used to transport the magnetic protective ring 5 from the third storage platform 224 to the conveyor belt 32. Similarly, the first drive mechanism 11 simultaneously drives the first feeding platform 211, the second feeding platform 221, and the third feeding platform 223. The second feeding platform 221 moves up and down along the side wall of the third storage platform 224. The hopper 212, the first feeding platform 211, the second feeding platform 221, the second storage platform 222, the third feeding platform 223, and the third storage platform 224 form a stepped structure. The hopper 212 and the first feeding platform 211 form the first step, the second feeding platform 221 and the second storage platform 222 form the second step, and the third feeding platform 223 and the third storage platform 224 form the third step. This stepped feeding assembly 22, along with the synchronous transport of the magnetic protective ring 5, better prevents damage to the magnetic protective ring 5 from falling from a height during upward transport due to excessive transport distance.

[0052] Since the hopper 21 is used to store a relatively large number of magnetic rings 5, it also includes a first baffle 213, a second baffle 214, and a back plate 215 to better accommodate the magnetic rings 5. The first baffle 213, the second baffle 214, and the back plate 215 are all vertically mounted on the base 1. One side of the first baffle 213 is connected to one side of the hopper 212, and one side of the second baffle 214 is connected to the other side of the hopper 212. The back plate 215, the first feeding platform 211, the second feeding platform 221, the third feeding platform 223, the second storage platform 222, and the third storage platform 224 are all located between the first baffle 213 and the second baffle 214. The third feeding platform 223 is located between the third storage platform 224 and the back plate 215. The back plate 215 is connected to the conveyor belt 32. The first baffle 213 and the second baffle 214 are equivalent to two side plates. The two side plates, the back plate 215, the hopper 212, and the first loading platform 211 can form a cavity structure. The hopper 212 can support a sufficient number of magnetic protective rings 5, while the first baffle 213, the second baffle 214, and the back plate 215 can prevent the magnetic protective rings 5 ​​from falling out. Furthermore, when the first loading platform 211 moves, the first baffle 213 and the second baffle 214 can also prevent the magnetic protective rings 5 ​​from falling out. Even when the second loading platform 221 and the third loading platform 223 transport the magnetic protective rings 5, the first baffle 213 and the second baffle 214 can still prevent the magnetic protective rings 5 ​​from falling out.

[0053] The top edge of the back plate 215 is connected to the conveyor belt 32. The back plate 215 is inclined from the top edge towards the hopper 212. The first loading platform 211, the second loading platform 221, the third loading platform 223, the second storage platform 222, and the third storage platform 224 are all arranged parallel to the back plate 215. That is, the first loading platform 211, the second loading platform 221, the third loading platform 223, the second storage platform 222, and the third storage platform 224 are all inclined. Therefore, when the first loading platform 211, the second loading platform 221, and the third loading platform 223 are transported upwards, it is equivalent to transporting upwards along a slope, which can transport the magnetic protective ring 5 with less effort and can also better prevent the magnetic protective ring 5 from falling off during transportation.

[0054] In this embodiment, the conveying mechanism 3 further includes a second distributor 35, which is installed on the conveyor belt 32. The second distributor 35 is used to remove the magnetic ring 5 when it is detected that the length of the magnetic ring 5 currently passing through the second distributor 35 on the conveyor belt 32 is greater than a predetermined length.

[0055] More specifically, the second distributor 35 includes a first jet assembly 351, a mounting bracket 352, and a sensing assembly. The mounting bracket 352 is connected to the conveyor belt 32. The first jet assembly 351 includes a first jet pipe and a first air valve. Both the first jet pipe and the sensing assembly are mounted on the mounting bracket 352. Both the first air valve and the sensing assembly are connected to the power control mechanism 4. The first jet pipe is connected to an external air source. The sensing assembly is used to detect the length of the magnetic retaining ring 5 and send a detection signal to the power control mechanism 4. The power control mechanism 4 is used to control the opening and closing of the first air valve according to the detection signal. In practical applications, the sensing assembly may include two sensors. The distance between the two sensors can be set to be slightly greater than or equal to the height of a single magnetic retaining ring 5, but the distance between the two sensors must be less than the sum of the heights of the two magnetic retaining rings 5. The purpose of setting the sensor distance in this way is to ensure that only a single magnetic retaining ring 5 is allowed to pass through, and nested or twisted magnetic retaining rings 5 ​​are not allowed to pass through. For example, consider two infrared sensors. After the magnetic ring 5 passes the first infrared sensor, it reaches the second. If the two magnetic rings 5 ​​are twisted together, the other end of the magnetic ring 5 will still correspond to the sensing position of the first infrared sensor. Both infrared sensors can send detection signals to the power control mechanism, indicating a twisted state. Therefore, the power control mechanism 4 can open the first air valve and blow the magnetic ring 6 away from the conveyor belt 32 by blowing air. The first distributor 34 continuously blows air through the first air jet pipe, with the air jet direction facing the conveyor belt 32. By continuously blowing air, the gas ejected from the first air jet pipe 14 can directly hit the outer wall of the magnetic ring 5, thus creating resistance to the forward movement of the magnetic ring 5. Continuous air jetting can knock the magnetic ring 5 off. Therefore, the first distributor 34 can prevent the twisted magnetic ring 5 from passing. The first air jet pipe in the first distributor 34 continuously sprays air, so the first air valve can be a manual air valve, which can be manually opened when the whole machine needs to be started, or it can be an automatic air valve, which can be connected to the power control mechanism 4 and opened and closed by the power control mechanism 4.

[0056] Furthermore, the second distributor 35 also includes a pushing assembly 353, which includes a push-pull rod, a push-pull motor, and a pushing plate. The push-pull motor is connected to the power control mechanism. One end of the push-pull rod is connected to the push-pull motor, and the other end is connected to the pushing plate. The mounting bracket 352 is disposed on one side of the conveyor belt, and the pushing plate is embedded in the mounting bracket 352 and can move to the other side of the conveyor belt under the push of the push-pull rod.

[0057] On the other hand, the second distributor 35 includes a limiting plate 354, an infrared beam sensor, and a second jet assembly. The second jet assembly includes a second jet pipe and a second air valve. The second air valve is installed on the second jet pipe and is connected to an external air source. The second air valve and the infrared beam sensor are both connected to the power control mechanism 4. The limiting plate 354 is connected to the conveyor belt 32 and is installed behind the first distributor 34. The limiting plate 354 is used to limit the outer diameter of the magnetic ring 5 passing through the limiting plate 354, so that the magnetic ring within the limited outer diameter range can pass through. The infrared beam sensor is used to send an obstruction signal to the power control mechanism when it detects a magnetic ring standing in front of the limiting plate, so that the power control mechanism controls the second jet pipe to work.

[0058] Furthermore, even after the first distributor 34 and the second distributor 35 screen the placement of the magnetic protective rings 5, there is still a possibility that although a single magnetic protective ring 5 is placed upside down on the conveyor belt 32, its position on the conveyor belt 32 may not be straight, and it may be misaligned. Correction is needed to better suit the subsequent sorting and clamping of the magnetic protective rings 5. Therefore, the conveying mechanism also includes a position corrector 36, which is installed on the conveyor belt 32. The first distributor 34, the position corrector 36, and the second distributor 35 are arranged sequentially at intervals. The position corrector 36 is used to correct the placement position of the magnetic protective rings 5 ​​on the conveyor belt 32.

[0059] In this embodiment, a return feeder 6 is also included. The return feeder 6 is installed on the conveyor belt 32 and is connected to the second baffle 214. The return feeder 6 corresponds to the positions of the first distributor 34, the second distributor 35, and the third distributor 36. The return feeder 6 is used to guide the magnetic rings 5 ​​that have fallen from the conveyor belt 32 after being restricted by the first distributor 34 and / or the second distributor 35 and / or the third distributor 36 to the hopper 21. That is, the return feeder 6 corresponds to the positions of both the first distributor 34 and the second distributor 35, so that whether the magnetic rings 5 ​​are restricted from passing through the first distributor 34 or the second distributor 35, they can be guided back to the hopper 21 by the return feeder 6 when they fall.

[0060] Furthermore, the aforementioned return feeder 6 includes a first return feeder 61 and a second return feeder 62. The first return feeder 61 is mounted on the conveyor belt 32. One side of the first return feeder 61 and one side of the second return feeder 62 are both fixed to the feeding mechanism 2. The first return feeder 61 is used to guide the magnetic protective ring 5, which has fallen from the conveyor belt 32 after being limited by the first distributor 34 and / or the second distributor 35, to the second return feeder 42 or the feeding mechanism 3. The second return feeder 62 is used to guide the magnetic protective ring 6 to the feeding mechanism 2. One side of the first return feeder 61 and one side of the second return feeder 62 are both fixed to the feeding mechanism 2. The first return feeder 61 and the second return feeder 62 are connected, and the first return feeder 61 and the second return feeder 62 are inclined towards each other and form an angle. The first return feeder 61 is gradually inclined downward from the conveyor belt, and the second return feeder 62 is gradually inclined from the other side of the feeding mechanism 2 towards the feeding mechanism 3. Due to the arrangement of the first return tray 61 and the second return tray 62, when two or more magnetic rings 6 that are intertwined and nested are restricted by the second distributor 35 and fall from the first return tray 41 to the second return tray 42, the probability of the intertwined magnetic rings 5 ​​loosening is increased. Ultimately, when they fall back into the hopper 31, the magnetic rings 6 are more likely to remain in an isolated state, thus reducing the intertwining and nesting when the magnetic rings 5 ​​are transported from the hopper 21 to the conveyor belt 12 the next time, thereby increasing transmission efficiency. Furthermore, the inclined design of the first and second return trays 61 and 62 reduces the possibility of the magnetic rings 5 ​​being scratched.

[0061] In this embodiment, a limiter 37 is also provided on the conveyor belt 32. The distance between the limiter 37 and the end of the conveyor belt 32 is greater than the height of a single magnetic ring 5 but less than the sum of the heights of two magnetic rings 6. The purpose of the limiter 37 is to ensure that when an external device grabs a magnetic ring 5 at the end of the conveyor belt 32, it can only grab one magnetic ring 5 at a time, preventing the simultaneous grabbing of two or more magnetic rings 5.

[0062] Preferably, the conveying mechanism 3 further includes a directional filter 38. One side of the directional filter 38 is connected to the baffle plate 33, and the front end of the directional filter 38 forms a beveled notch facing the end direction. The directional filter 38 is arranged parallel to the conveyor belt. The directional filter 38 is used to limit the passage of the magnetic protective ring 5 that fits into the notch. The directional filter 38 is actually a plate, which is used to ensure that the opening direction of the magnetic protective ring 5 passing through the directional filter 38 is the same. The front end of the directional filter is set as a bevel, which is equivalent to having a triangular notch, so that the magnetic protective ring 5 that conforms to the direction can gradually fit into the directional filter 38 during the conveying process.
