Description

Technical Field

[0001] This invention relates to the field of motor manufacturing assembly tools, and more specifically to an automatic material dispensing device. 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 material identification and feeding is costly, and operators are prone to placing materials in the wrong direction, stacking them, and causing subsequent feeding 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. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an automatic material dispensing device that can realize automatic material dispensing and avoid errors caused by manual material dispensing.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] This invention provides an automatic material dispensing device, comprising:

The baffle plate is vertically disposed on the outside of the conveyor belt. The first distributor is installed on the conveyor belt. The conveyor belt is used to convey the magnetic ring. The first distributor is used to remove the magnetic ring when it is detected that the length of the magnetic ring currently passing the first distributor on the conveyor belt is greater than a certain length.

[0008] The power control mechanism is electrically connected to the first drive mechanism.

[0009] In this invention, as an optional embodiment, the conveyor belt is inclined downward toward the baffle plate.

[0010] In this invention, as an optional embodiment, the first 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.

[0011] In this invention, as an optional embodiment, the first distributor further includes a pushing assembly, which includes a push-pull rod, a push-pull motor, and a pushing plate.

[0012] In this invention, as an optional embodiment, the first distributor includes a limiting plate, 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 disposed on the second jet pipe and connected to an external air source. The second air valve and the infrared beam sensor are both connected to an electric control mechanism. The limiting plate is connected to a 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.

[0013] In this invention, as an optional embodiment, the conveying mechanism further includes a second distributor, which is mounted on the baffle plate and located in front of the first distributor. The installation height of the second distributor is greater than the diameter of the magnetic ring and less than the height of the magnetic ring, so that the second distributor allows only the horizontally placed magnetic ring on the conveyor belt to pass through at any one time.

[0014] In this invention, as an optional embodiment, the second distributor includes a connector and a distributor plate. The connector is mounted on the baffle plate, the distributor plate is connected to the connector, and the distributor plate is located above the conveyor belt.

[0015] In this invention, as an optional embodiment, the conveying mechanism further includes a position corrector, which is installed on the conveyor belt. The second distributor, the position corrector, and the first distributor are arranged in sequence at intervals. The position corrector is used to correct the placement position of the magnetic ring on the conveyor belt.

[0017] In this invention, as an optional embodiment, the conveying mechanism is further provided with a side baffle, the side baffle is connected to the baffle plate, and the feeding mechanism is located between the side baffle and the first distributor.

[0018] In this invention, as an optional embodiment, a return feeder is also connected to the conveyor belt, and the return feeder is connected to the feeding mechanism. The return feeder is positioned corresponding to the first distributor and the second distributor, and is used to guide the magnetic ring that has fallen off the conveyor belt after being limited by the first distributor and / or the second distributor to the feeding mechanism.

[0019] In this invention, as an optional embodiment, the return feeder includes a first return feeder and a second return feeder. The first return feeder is mounted on a conveyor belt. One side of the first return feeder and one side of the second return feeder are both fixed to the feeding mechanism. The first return feeder and the second return feeder are connected and are inclined to each other to form an angle. The first return feeder is gradually inclined downward from the conveyor belt, and the second return feeder is gradually inclined from the other side of the feeding mechanism toward one side of the feeding mechanism.

[0020] In this invention, as an optional embodiment, the conveyor belt is further provided with a limiter, the distance between the limiter and the end of the conveyor belt being greater than the height of a single magnetic ring but less than the sum of the heights of two magnetic rings.

[0021] 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. The directional filter is arranged parallel to the conveyor belt, and the directional filter is used to limit the passage of the magnetic ring of the directional filter so that the notch is just caught on the magnetic ring of the directional filter.

Under the control of the electric control mechanism, the first drive mechanism in the conveying mechanism is activated, thereby driving the conveyor belt to operate. The first sorter can remove the magnetic ring when it detects that the length of the magnetic ring currently passing through the first sorter on the conveyor belt is greater than a certain length. The device automatically classifies cases where at least two magnetic rings are twisted together, so that the conveyor belt passing through the first sorter only transports a single magnetic ring, thereby ensuring that there are no cases where magnetic rings are twisted together when transported to the destination.

Detailed Implementation

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

Unless otherwise specified, the materials and equipment used in this embodiment are commercially available.

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

[0035] 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.

[0036] 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.

[0037] This application provides an automatic material sorting device including a conveying mechanism and a power control mechanism. A first sorter is provided on the conveyor belt in the conveying mechanism. The conveyor belt is used to transport the magnetic rings. Under the control of the power control mechanism, the first drive mechanism in the conveying mechanism is activated, thereby driving the conveyor belt to operate. The first sorter can remove the magnetic ring when it detects that the length of the magnetic ring currently passing through the first sorter on the conveyor belt is greater than a certain length. The device automatically classifies cases where at least two magnetic rings are twisted together, so that the conveyor belt passing through the first sorter only transports a single magnetic ring, thereby ensuring that the magnetic rings transported to the destination do not have any magnetic rings twisted together.

[0038] Please refer to Figure 1-7 As shown, this embodiment provides an automatic material dispensing device, including a conveying mechanism 1 and an electrical control mechanism 2. The electrical control mechanism 2 is mainly used to provide circuit control, and therefore may include control components such as control circuits. The conveying mechanism 1 includes a first drive mechanism 11, a conveyor belt 12, a baffle plate 13, and a first distributor 14. The electrical control mechanism 2 is electrically connected to the first drive mechanism 11.

[0039] In this embodiment, the automatic material distribution device can be mounted on a base 5. Specifically, as one possible implementation, both the power control mechanism 2 and the conveying mechanism 1 are mounted on the base 5. The conveyor belt 12 of this embodiment is connected to the first drive mechanism 11. The baffle plate 13 is vertically arranged on the outside of the conveyor belt 12. The first distributor 14 is mounted on the conveyor belt 12. The conveyor belt 12 is used to transport the magnetic protective ring 6. The first distributor 14 is used to remove the magnetic protective ring 6 when it detects that the length of the magnetic protective ring 6 currently passing the first distributor 14 on the conveyor belt 12 is greater than a predetermined length. When the magnetic protective ring 6 is transported onto the conveyor belt 12, there are several possibilities for its placement on the conveyor belt 12. In this embodiment, when the magnetic protective ring 6 is transported from an external mechanism to the conveyor belt 12, there are several placement options for the magnetic protective ring 6 on the conveyor belt 12: two or more magnetic protective rings 6 are stacked vertically; two or more magnetic protective rings 6 are nested and twisted together; a single magnetic protective ring 6 is placed vertically; multiple twisted magnetic protective rings 6 are placed vertically; and a single magnetic protective ring 6 is placed horizontally. The correct placement of the magnetic protective ring 6 should be upside down on the conveyor belt 12. However, other possibilities include the magnetic protective ring 6 being placed vertically on the conveyor belt 12, multiple magnetic protective rings 6 being stacked on top of each other in height, or several magnetic protective rings 6 being nested and twisted together, etc. To ensure that the final output magnetic protective ring 6 is in the correct position, a first distributor 14 is set up to screen and remove nested and twisted magnetic protective rings 6, preventing such magnetic protective rings 6 from continuing to be conveyed.

[0040] In a preferred embodiment, the first classifier 14 may be specifically configured as follows: it includes a first jet assembly 141, a mounting bracket 142, and a sensing assembly. The mounting bracket 142 is connected to the conveyor belt. The first jet assembly 141 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 142. 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 ring 6 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. In practical applications, the sensing assembly may include two sensors. The distance between the two sensors may be slightly greater than or equal to the height of a single magnetic ring 6, but the distance between the two sensors must be less than the sum of the heights of the two magnetic rings 6. The purpose of setting the sensor distance in this way is to ensure that only a single magnetic ring 6 is allowed to pass through, and that nested or twisted magnetic rings 6 are not allowed to pass through. For example, consider two infrared sensors. After the magnetic ring 6 passes the first infrared sensor, it reaches the second. If the two magnetic rings 6 are twisted together, the other end of the magnetic ring 6 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 can open the first air valve and blow the magnetic ring 6 away from the conveyor belt 12 by blowing air. The first distributor 14 continuously blows air through the first air jet pipe, with the air jet direction facing the conveyor belt 12. By continuously blowing air, the air ejected by the first distributor 14 can directly hit the outer wall of the magnetic ring 6, thus creating resistance to the forward movement of the magnetic ring 6. Continuous air jetting can knock the magnetic ring 6 off, thus preventing the twisted magnetic ring 6 from passing. The first jet pipe in the first distributor 14 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 2 and opened and closed by the power control mechanism 2.

[0041] More specifically, the first distributor 14 also includes a pushing assembly 143, 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 142 is disposed on one side of the conveyor belt 12. The pushing plate is embedded in the mounting bracket 142 and can move to the other side of the conveyor belt 12 under the push of the push-pull rod.

[0042] In another example, the first distributor 14 can also be a limiting plate, 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 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.

[0043] In a preferred embodiment, the conveyor belt 12 is inclined. Specifically, the conveyor belt 12 is inclined downwards toward the baffle plate 13. That is, the conveyor belt 12 is inclined from the inside to the outside, so that when the magnetic ring 6 is conveyed to the conveyor belt 12, due to this inclined structural design, the magnetic ring 6 can be prevented from falling off, ensuring that the magnetic ring 6 can be transported normally on the conveyor belt 12.

[0044] In a further preferred embodiment, this application may also include a second distributor 15. The second distributor 15 is mounted on the baffle plate 13 and located in front of the first distributor 14. The mounting height of the second distributor 15 is greater than the diameter of the magnetic ring 6 and less than the height of the magnetic ring 6, so that the second distributor 15 allows only the transversely placed magnetic ring 6 on the conveyor belt to pass through at any given time.

[0045] It should be noted that this application uses the conveying direction of the conveyor belt 12 as an indicator, with the forward direction of the conveyor belt 12 being considered rearward, and conversely, the opposite direction to the forward direction of the conveyor belt 12 being considered forward. The purpose of the second distributor 15 in this embodiment is mainly to prevent two or more magnetic rings 6 from passing smoothly when they are stacked on the conveyor belt 12. The first distributor 14 is installed at a certain height, allowing a single magnetic ring 6 to pass, specifically allowing only horizontally placed magnetic rings 6 to pass. Assuming two magnetic rings 6 are in a twisted state, that is, two magnetic rings 6 are overlapping and embedded together, since the two magnetic rings 6 are not stacked in height and their height does not exceed the height of the second distributor 15, they can also pass through the second distributor 15. The second distributor 15 is triangular in shape, with a fixed plate extending upward from one side of the triangular baffle. The fixed plate is fixed to the baffle plate 13. The triangular baffle extends from the inside to the outside along the conveying direction of the conveyor belt 12. Therefore, when the magnetic rings 6 are transported by the conveyor belt 12, the magnetic rings 6 above the second layer are gradually blocked by the triangular baffle and fall off, thus achieving material distribution. Based on the second distributor 15, since the second distributor 15 is located in front of the first distributor 14, and the second distributor 15 has already filtered the magnetic rings 6 stacked on top and the vertically placed magnetic rings 6, the magnetic rings 6 on the conveyor belt 12 after passing through the second distributor 15 include the following situations: two or more magnetic rings 6 nested and twisted together, or a single magnetic ring 6 placed horizontally. Only a single magnetic ring 6 placed horizontally is ultimately suitable for assembly with the motor. After passing through the first distributor 14, only the magnetic protective rings 6 that meet the requirements and are placed horizontally remain on the conveyor belt 12. Specifically, the second distributor 15 includes a connector 151 and a distribution plate 152. The connector 151 is mounted on the baffle plate 152, and the distribution plate 152 is connected to the connector 151. The distribution plate 152 is located above the conveyor belt 12, and the installation height of the distribution plate 152 is greater than the diameter of the magnetic protective ring 6 but less than the height of the magnetic protective ring 6.

[0046] Although the first distributor 14 and the second distributor 15 screen the placement of the magnetic protective rings 6, there is still a possibility that although a single magnetic protective ring 6 is placed upside down on the conveyor belt 12, its position on the conveyor belt 12 may not be straight, and its position may be off-center. Correction is needed to better suit the subsequent sorting and clamping of the magnetic protective rings 6. Therefore, the conveying mechanism also includes a position corrector 16, which is installed on the conveyor belt 12. The second distributor 15, the position corrector 16, and the first distributor 14 are arranged in a sequential, spaced-apart configuration. The position corrector 16 is used to correct the placement position of the magnetic protective rings 6 on the conveyor belt 12.

[0047] In a preferred embodiment, the conveying mechanism 1 of this application is further connected to a feeding mechanism 3, which is used to accommodate the magnetic protective rings 6 and transport the magnetic protective rings 6 to the conveyor belt 12. Specifically, the feeding mechanism 3 may include a hopper 31 and a feeding assembly 32. The feeding assembly 32 is mounted on the hopper 31 and connected to a second drive mechanism. The feeding assembly 32 is used to transport the magnetic protective rings 6 in the hopper 31 upward under the drive of the second drive mechanism. The second drive mechanism typically includes a motor and a drive shaft. The drive shaft is connected to the motor, which is connected to a power control mechanism 2. The drive shaft is also connected to the feeding assembly 32, so that the power control mechanism 2 controls the motor to work, the motor drives the drive shaft to rotate, and thus drives the feeding assembly 32 to move. Specifically, since the feeding assembly 32 needs to transport the magnetic protective rings 6 in the hopper 31 upward, the feeding assembly 32 moves upward under the drive of the drive shaft. The hopper 31 is used to store a relatively large number of magnetic protective rings 6. Since the feeding assembly 32 transports the magnetic protective rings 6 upward, it can be understood that the hopper 31 is installed at a relatively low position.

[0048] In this embodiment, the hopper 31 specifically includes a first feeding platform and a hopper. The hopper is used to store a relatively large amount of magnetic rings 6. When the first feeding platform is stationary and not in operation, its top surface is close to the hopper, or flush with the bottom surface of the hopper, or slightly higher than the bottom surface of the hopper, or slightly lower than the bottom surface of the hopper. When the first feeding platform is in operation, it moves up and down. Combined with the feeding assembly 32, which includes a second feeding platform and a second storage platform, both the first feeding platform and the second feeding platform are connected to the second drive mechanism. The installation height of the second feeding platform and the second storage platform is higher than that of the first feeding platform. The second storage platform is located between the first feeding platform and the second feeding platform. The first feeding platform is used to move in the height direction under the drive of the second drive mechanism to transport the magnetic rings 6 in the hopper to the second storage platform. The second feeding platform is used to move in the height direction under the drive of the second drive mechanism to transport the magnetic rings 6 in the second storage platform to the conveyor belt 12. Typically, the second drive mechanism simultaneously drives the first and second loading platforms. Therefore, the first and second loading platforms move upwards or downwards simultaneously. When moving upwards, the first loading platform transports the magnetic ring 6 to the second loading platform and the second storage platform. The second loading platform then transports the magnetic ring 6 from the second storage platform or from within the second loading platform upwards to the conveyor belt 12. The first loading platform moves up and down along the side wall of the second storage platform. Furthermore, the loading assembly 32 also includes a third loading platform and a third storage platform. The third loading platform is connected to the second drive mechanism. The installation height of both the third loading platform and the third storage platform is higher than that of the second loading platform and the second storage platform. The third storage platform is located between the third loading platform and the second loading platform. The third storage platform is used to store the magnetic ring 6 from the second loading platform and to transport the magnetic ring 6 from the third storage platform to the conveyor belt 12. Similarly, the second drive mechanism simultaneously drives the first, second, and third feeding platforms, with the second feeding platform moving up and down along the side wall of the third storage platform. The hopper and the first, second, and second feeding and storage platforms, as well as the third feeding and storage platforms, form a stepped structure, with the hopper and first feeding platform forming the first step, the second feeding and storage platforms forming the second step, and the third feeding and storage platforms forming the third step. This stepped feeding assembly 32, along with the synchronous transport of the magnetic protective ring 6, better prevents damage to the magnetic protective ring 6 from falling from a height during upward transport due to excessive transport distance.

[0049] Since the hopper 31 is used to store a relatively large number of magnetic rings 6, it also includes a baffle and a back plate to better accommodate the magnetic rings 6. The baffle is connected to the baffle plate 13, and the feeding mechanism 3 is located between the baffle and the first distributor. Specifically, the baffle can be divided into a first baffle and a second baffle. The first baffle, the second baffle, and the back plate are all vertically mounted on the base 5, and one side of the first baffle is connected to one side of the hopper, and one side of the second baffle is connected to the other side of the hopper. The back plate, the first feeding platform, the second feeding platform, the third feeding platform, the second storage platform, and the third storage platform are all located between the first baffle and the second baffle, and the third feeding platform is located between the third storage platform and the back plate. The back plate is connected to the conveyor belt 12. The first and second baffles act as two side plates. These two side plates, along with the back plate, the hopper, and the first material platform, form a cavity structure. The hopper can support a sufficient number of magnetic protective rings 6. The first and second baffles, along with the back plate, prevent the magnetic protective rings 6 from falling out. Furthermore, when the first material platform moves, the first and second baffles also prevent the magnetic protective rings 6 from falling out. Even when the second and third material platforms are transporting the magnetic protective rings 6, the second and third baffles can still prevent them from falling out.

[0050] The top edge of the aforementioned back plate is connected to the conveyor belt 12. The back plate is inclined from the top edge towards the hopper. The first, second, third, second, and third feeding platforms are all arranged parallel to the back plate. That is, the first, second, third, second, and third feeding platforms are all inclined, so when the first, second, and third feeding platforms are transported upwards, it is equivalent to transporting upwards along a slope, which can transport the magnetic protective ring 6 more effortlessly and can also better prevent the magnetic protective ring 6 from falling off during transportation.

[0051] The conveying mechanism 1 in the embodiment is also provided with a side baffle 17, which is connected to the baffle plate 13, and the feeding mechanism 3 is located between the side baffle 17 and the first distributor 14.

[0052] In this embodiment, a return feeder 4 is also connected to the conveyor belt 12, and the return feeder 4 is connected to the feeding mechanism 3. The return feeder 4 corresponds to the positions of the first distributor 14 and the second distributor 15, and is used to guide the magnetic protective ring 6 that has fallen from the conveyor belt 12 after being limited by the first distributor 14 and / or the second distributor 15 to the feeding mechanism 3. Further, the return feeder 4 includes a first return plate 41 and a second return plate 42. The first return plate 41 is installed on the conveyor belt 12, and one side of the first return plate 41 and one side of the second return plate 42 are both fixed to the feeding mechanism 3. The first return plate 41 is used to guide the magnetic protective ring 6 that has fallen from the conveyor belt 12 after being limited by the first distributor 14 and / or the second distributor 15 to the second return plate 42 or the feeding mechanism 3. The second return plate 42 is used to guide the magnetic protective ring 6 to the feeding mechanism 3. One side of the first return plate 41 and one side of the second return plate 42 are both fixed to the feeding mechanism 3. The first return plate 41 and the second return plate 42 are connected, and the first return plate 41 and the second return plate 42 are inclined to each other and form an angle. The first return plate 41 is gradually inclined downward by the conveyor belt, and the second return plate 42 is gradually inclined from the other side of the feeding mechanism 3 toward one side of the feeding mechanism 3.

[0053] Due to the arrangement of the first return tray 41 and the second return tray 42, when two or more magnetic rings 6 that are intertwined and nested are passed through the third distributor 16 and fall from the first return tray 41 to the second return tray 42, the probability of the intertwined magnetic rings 6 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 they are transported from the hopper 31 to the conveyor belt 12 the next time, thereby increasing transmission efficiency. Furthermore, the inclined design of the first and second return trays 41 and 42 reduces the possibility of the magnetic rings 6 being scratched.

[0054] In another example, combined Figure 3The return feeder 4 can also be configured such that one side of the first return feeder 41 and one side of the second return feeder 42 are both fixed on the feeding mechanism 3. The first return feeder 41 is located above the second return feeder 42, so that there is a height difference between the first return feeder 41 and the second return feeder 42. The first return feeder 41 is used to guide the magnetic ring 6 that has fallen from the conveyor belt 12 after being limited by the first distributor 14 and / or the second distributor 15 and / or the third distributor 16 to the second return feeder 42. The second return feeder 42 is used to guide the magnetic ring 6 to the feeding mechanism 3. Because there is a height difference between the first return plate 41 and the second return plate 42, when two or more magnetic rings 6 that are intertwined and nested are restricted by the third distributor 16 and fall from the first return plate 41 to the second return plate 42, the probability of the intertwined magnetic rings 6 loosening is increased. Finally, when they fall back into the hopper 31, the magnetic rings 6 are more likely to remain in an isolated state, so that when the magnetic rings 6 are transported from the hopper 31 to the conveyor belt 12 next time, the intertwining and nesting will be reduced, thereby increasing the transmission efficiency.

[0055] In this embodiment, a limiter 18 is also provided on the conveyor belt 12. The distance between the limiter 18 and the end of the conveyor belt 12 is greater than the height of a single magnetic ring 6 but less than the sum of the heights of two magnetic rings 6. The purpose of the limiter 18 is to ensure that when an external device grabs a magnetic ring 6 at the end of the conveyor belt 12, it can only grab one magnetic ring 6 at a time, preventing the simultaneous grabbing of two or more magnetic rings 6.

[0056] In addition, the conveying mechanism 1 also includes a directional filter 19. One side of the directional filter 19 is connected to the baffle plate 13, and the front end of the directional filter 19 forms a beveled notch facing the end direction. The directional filter 19 is arranged parallel to the conveyor belt 12. The directional filter 19 is used to limit the passage of the magnetic protective ring 6, which is just fitted into the notch. The directional filter 19 is actually a plate, which is used to ensure that the opening direction of the magnetic protective ring 6 passing through the directional filter 19 is the same. The front end of the directional filter is set as a bevel, which is equivalent to a triangular notch, so that the magnetic protective ring 6 that conforms to the direction can gradually be fitted into the directional filter 19 during the conveying process.
