Description

Technical Field

[0001] The present invention relates to the technical field of transmissions, and in particular to a system for conveying magnetic powder cores from a press to heat treatment equipment and a control method thereof. Background Art

[0002] Magnetic powder cores are made by compacting magnetic powder. The powder is then pressed into shape in a press, then fed onto a belt conveyor system. The conveyor system then transports the powder core to a heat treatment facility for heat treatment, followed by a magnetic flux treatment to impart excellent magnetic properties. After compacting the powder, the surface of the powder core will likely contain a certain amount of magnetic powder. This adherent powder must be removed before heat treatment to ensure a smooth surface.

[0003] Among them, the function of removing the magnetic powder attached to the surface of the magnetic powder core is usually integrated into the conveying system between the press and the heat treatment equipment. A belt conveyor system is usually used. In order to remove the magnetic powder attached to the surface of the magnetic powder core, an airflow nozzle and its corresponding pipeline are arranged, and a high-speed airflow is used to blow the magnetic powder core being conveyed to remove the magnetic powder attached to the surface of the magnetic powder core.

[0004] However, when using high-speed airflow to clean the surface of the magnetic powder core, if the airflow is too small, the attached magnetic powder cannot be effectively removed. If the airflow is too large, the magnetic powder core will move on the conveyor belt, affecting the heat treatment effect. Regardless of the size of the airflow, the airflow cannot effectively act on the bottom surface of the magnetic powder core that contacts the conveyor belt, and the magnetic powder mold cannot be effectively cleaned. Therefore, the conveying system of the magnetic powder mold from the press to the heat treatment equipment in the prior art still has the technical problem of being unable to effectively clean the surface of the magnetic powder core. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a conveying system for magnetic powder cores from a press to a heat treatment device and a control method thereof, so as to solve the technical problem in the prior art that the conveying system for magnetic powder cores from a press to a heat treatment device cannot effectively clean the surface of the magnetic powder cores.

[0006] A first aspect of the present invention is to provide a system for conveying magnetic powder cores from a press to a heat treatment device, characterized in that the conveying system comprises:

[0007] A conveyor belt and a support frame, wherein the support frame is provided between the press and the heat treatment equipment, and is provided with at least two transmission rollers and a drive unit for driving the transmission rollers to rotate. The conveyor belt is rotatably connected between the transmission rollers, and the drive unit is used to drive at least one of the transmission rollers to rotate so that the conveyor belt circulates along a preset direction;

[0008] a pressing mechanism located between the first working portion and the second working portion of the conveyor belt, comprising a rotating bracket and pressing rods arranged parallel to both ends of the rotating bracket, the rotating bracket being rotatably connected to the support frame, and the two pressing rods being in initial state respectively in contact with the bottom surface of the first working portion;

[0009] an air blowing mechanism, provided on a first side surface of the first working portion;

[0010] a powder collecting mechanism, disposed on the second side surface of the first working portion;

[0011] Among them, when the driving unit drives the conveyor belt to rotate along a preset direction, it drives the pressure rod in the initial state to rotate in the same direction to support the first working part, so that the first working part is arched, and the conveyor belt continues to move. The pressure rod is separated from the first working part and falls naturally under the action of gravity, and the magnetic powder core is separated from the first working part. The blowing mechanism is used to output airflow to the magnetic powder core to remove magnetic powder attached to the surface, and the powder collecting mechanism is used to generate negative pressure to collect the falling magnetic powder.

[0012] According to one aspect of the above technical solution, the pressing rod includes a first pressing rod and a second pressing rod parallel to each other, and the first pressing rod and the second pressing rod are respectively fixedly connected to two ends of the rotating bracket.

[0013] According to one aspect of the above technical solution, the rotating bracket is rotatably connected to the support frame through a rotating shaft, and the rotation axis of the rotating bracket is not lower than the first working part, so that the first support roller and the second support roller can simultaneously contact the bottom surface of the first working part in the initial state.

[0014] According to one aspect of the above technical solution, the inner side surface of the conveyor belt, and the surfaces of the first pressing rod and the second pressing rod are all friction surfaces.

[0015] According to one aspect of the above technical solution, the blowing mechanism includes a blowing port provided on the support frame, and a first conduit and an air pump connected to the blowing port.

[0016] According to one aspect of the above technical solution, the powder collecting mechanism includes an adsorption port, and a second conduit and a negative pressure generator connected to the adsorption port.

[0017] According to one aspect of the above technical solution, the powder collecting mechanism further includes a collecting container connected to the adsorption port, and the collecting container is arranged on the supporting frame.

[0018] According to one aspect of the above technical solution, the pressing mechanism further includes an angle sensor provided on the rotating bracket or the pressing rod.

[0019] A second aspect of the present invention is to provide a method for controlling a system for conveying magnetic powder cores from a press to a heat treatment device. The method is used to control the system for conveying magnetic powder cores from a press to a heat treatment device described in the above technical solution. The method comprises:

[0020] Controlling the driving unit to move, driving the transmission roller to rotate and driving the conveyor belt to circulate along a preset direction;

[0021] The circular rotation of the conveyor belt drives the pressing mechanism to move in the same direction, and the pressing roller contacts the bottom surface of the first working part to support the first working part;

[0022] The conveyor belt continues to rotate to separate the pressing roller from the first working portion, and the pressing roller naturally falls under the action of gravity, so that the magnetic powder core is separated from the first working portion;

[0023] controlling the air blowing mechanism to blow air toward the magnetic powder core so that the magnetic powder attached to the surface of the magnetic powder core moves with the air flow;

[0024] The powder collecting mechanism is controlled to generate negative pressure to collect the floating magnetic powder.

[0025] According to one aspect of the above technical solution, when the angle sensor detects that the pressing roller in contact with the bottom surface of the first working part drops rapidly from the apex position and increases the angular acceleration, the blowing mechanism and the powder collecting mechanism move successively.

[0026] Compared with the prior art, the conveying system of the magnetic powder core from the press to the heat treatment equipment shown in the present invention has the following beneficial effects:

[0027] By arranging a conveyor belt and a support frame, a pressing mechanism, a blowing mechanism and a powder collecting mechanism, when the driving unit drives the conveyor belt to rotate in a preset direction, the pressing rod in the initial state will be driven to rotate in the same direction to support the first working part, so that the first working part will be arched, and the conveyor belt continues to move, the pressing rod will separate from the first working part and fall naturally under the action of gravity, and the magnetic powder core will be separated from the first working part. The blowing mechanism is used to output airflow to the magnetic powder core to remove the magnetic powder attached to the surface, and the powder collecting mechanism is used to generate negative pressure to collect the falling magnetic powder. The present invention can drive the pressing mechanism to rotate during the rotation process of the conveyor belt to cyclically support and relax it by arranging a pressing mechanism with a specific structure, thereby effectively cleaning the magnetic dust attached to the surface of the magnetic powder core and collecting the powder, thereby ensuring the cleanliness of the magnetic powder core. The existing magnetic powder type conveying system from the press to the heat treatment equipment still has the technical problem of not being able to effectively clean the surface of the magnetic powder core.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Example 1

[0040] See also Figure 1-5 The first embodiment of the present invention provides a system for conveying magnetic powder cores 20 from a press to a heat treatment device. The system is used to convey the magnetic powder cores 20 compacted by the press from one side of the press to the other side of the heat treatment device, that is, from the output end of the press to the input end of the heat treatment device. The system includes:

[0041] A conveyor belt 11 and a support frame 12, wherein the support frame 12 is provided between the press and the heat treatment equipment, and at least parts of both ends of the support frame 12 extend into the interior of the press and the heat treatment equipment, respectively, so as to achieve docking with the press and the heat treatment equipment through the conveyor belt 11, and the support frame 12 is provided with at least two transmission rollers 13 and a driving unit 14 for driving the transmission rollers 13 to rotate, both transmission rollers 13 are rotatably connected to the support frame 12, and the transmission rollers 13 are provided with driven gears, the conveyor belt 11 is rotatably connected between the transmission rollers 13, and the driving unit 14 is used to drive at least one of the transmission rollers 13 to rotate so that the conveyor belt 11 circulates along a preset direction;

[0042] Among them, the support frame 12 is a frame structure, which is made of a plurality of profiles welded together. The two transmission rollers 13 are respectively rotatably arranged on the profiles on both sides of the support frame 12, that is, the transmission rollers 13 can rotate relative to the support frame 12, and the two ends of the conveyor belt 11 are respectively sleeved on the transmission rollers 13. When the transmission rollers 13 rotate, the steering force of the transmission rollers 13 can be converted into the moving force of the conveyor belt 11, so that the conveyor belt 11 can transport the magnetic powder core 20 located thereon when it circulates.

[0043] By way of example and not limitation, the driving unit 14 is a servo motor, which is disposed on the support frame 12 . A driving gear is provided on the motor shaft of the servo motor. The driving gear and the driven gear on the transmission roller 13 are connected through a transmission mechanism to drive the movement of the transmission roller 13 and the conveyor belt 11 through the movement of the driving unit 14 .

[0044] More specifically, the driving gear of the driving unit 14 and the driven gear of the transmission roller 13 are driven by a belt drive such as a chain drive or a belt drive.

[0045] It should be noted here that since the product conveyed by the conveyor belt 11 is a magnetic powder core 20, as mentioned in the background technology, after the magnetic powder core 20 is pressed into shape, the surface of the magnetic powder core 20 will inevitably be stained with some magnetic powder. After the magnetic powder core 20 is pressed into shape by the press, the magnetic powder core 20 needs to be heat-treated as soon as possible to improve the structural strength of the magnetic powder core 20. In order to avoid the magnetic powder attached to the surface of the magnetic powder core 20 from being heat-treated, the magnetic powder attached to the surface of the magnetic powder core 20 needs to be removed before the magnetic powder core 20 is heat-treated to ensure the cleanliness of the magnetic powder mold, thereby ensuring the smoothness of the magnetic powder core 20 after heat treatment.

[0046] In this embodiment, the conveying system also includes a pressing mechanism 30, which is used to cyclically press the conveyor belt 11 that is conveying the magnetic powder core 20, causing the circulating conveyor belt 11 to produce at least partial deformation, thereby separating the magnetic powder core 20 from the surface of the conveyor belt 11, which is equivalent to the magnetic powder core 20 being thrown up by the conveyor belt 11, providing the magnetic powder core 20 with air time, so that the magnetic powder attached to the surface of the magnetic powder core 20 can be cleaned during the air time, which can effectively improve the cleaning ability.

[0047] Among them, the conveyor belt 11 is circularly rotated and has an elliptical shape. Therefore, in this embodiment, the portion of the conveyor belt 11 facing upward and capable of carrying the magnetic powder core 20 is set as the first working portion 11a, and the second working portion 11b of the conveyor belt 11 facing downward is set. The first working portion 11a and the second working portion 11b generally refer to a certain part of the conveyor belt 11 during the working process, and do not specifically refer to specific parts of the conveyor belt 11.

[0048] Specifically, the pressing mechanism 30 is arranged between the first working part 11a and the second working part 11b of the conveyor belt 11. In simple terms, the pressing mechanism 30 is arranged inside the conveyor belt 11. The pressing mechanism 30 includes a rotating bracket 31 and a pressing rod parallel to the two ends of the rotating bracket 31. The pressing rod includes a first pressing rod 32 and a second pressing rod 33 parallel to each other. The first pressing rod 32 and the second pressing rod 33 are respectively fixedly connected to the two ends of the rotating bracket 31; the rotating bracket 31 is rotatably connected to the support frame 12 through a rotating shaft, and the rotation axis of the rotating bracket 31 is not lower than the first working part 11a, so that the first support roller and the second support roller can simultaneously contact the bottom surface of the first working part 11a in the initial state.

[0049] When the conveyor belt 11 is not moving, all components within the pressing mechanism 30 are in their initial state. At this point, the rotating bracket 31 is flush with the conveyor belt 11, and the first pressing rod 32 and the second pressing rod 33 are in contact with the first working portion 11a at the input and output ends thereof, respectively. It is worth noting that the surfaces of the first pressing rod 32 and the second pressing rod 33 and the bottom surface of the first working portion 11a are not smooth, but rather are provided with a friction structure having a relatively large particle size. This allows the first pressing rod 32 and the second pressing rod 33 to rotate in sequence as the conveyor belt 11 cyclically rotates, thereby achieving cyclic support and relaxation of the first working portion 11a on the conveyor belt 11 as the first pressing rod 32 and the second pressing rod 33 rotate about the axis of the rotating bracket 31.

[0050] Specifically, when the conveyor belt 11 is cyclically rotating, since the bottom surface of the first working portion 11a is in contact with the surface of the first pressure rod 32, and there is a strong friction force between the bottom surface of the first working portion 11a and the first pressure rod 32, the conveyor belt 11 continues to rotate, and the first pressure rod 32 and its rotating bracket 31 will be driven to rotate in the same direction, and the first pressure rod 32 will gradually support the first working portion 11a, causing the first working portion 11a to produce elastic deformation and arch, and the arching is slow, and the arching speed is determined by the rotation speed of the conveyor belt 11. Therefore, the magnetic powder core 20 located between the first working portions 11a It will continue to move with the first working part 11a. As the conveyor belt 11 continues to rotate, the first pressing rod 32 will instantly separate from the bottom surface of the first working part 11a. Under the rotational force applied by the first working part 11a and the action of gravity, the first pressing rod 32 will quickly rotate and fall. At this time, the first working part 11a will instantly lose its support, and the first working part 11a will quickly rebound to a flush state, and the magnetic powder core 20 will be thrown up; then the second pressing rod 33 will contact the bottom surface of the first working part 11a to support it. In this cycle, the magnetic powder core 20 located on the first working part 11a can be thrown up and made airborne.

[0051] Among them, since the rotation of the conveyor belt 11 drives the pressing mechanism 30 to rotate, through a specific structural setting, the pressing mechanism 30 can cyclically support and relax the conveyor belt 11, and can effectively throw the magnetic powder core 20 located on the conveyor belt 11 into the air, so as to facilitate the cleaning of the magnetic powder attached to the surface of the magnetic powder core 20.

[0052] In this embodiment, an air blowing mechanism 40 and a powder collecting mechanism 50 are provided to clean and collect the magnetic powder attached to the surface of the magnetic powder core 20 , so as to determine the cleanliness of the magnetic powder core 20 .

[0053] Specifically, the blowing mechanism 40 is arranged on the first side of the first working part 11a, and the blowing mechanism 40 includes a blowing port provided on the support frame 12, and a first conduit and an air pump connected to the blowing port; the air pump is used to store compressed gas, and the first conduit is used to output the compressed gas stored in the air pump to the blowing port at a preset position on the support frame 12, and the blowing port is located on the first side of the first working part 11a, so as to output a high-speed airflow to the thrown magnetic powder core 20 through the blowing port preset on the support frame 12 for cleaning.

[0054] Specifically, the powder collection mechanism 50 is arranged on the second side of the first working part 11a, and the powder collection mechanism 50 includes an adsorption port, and a second conduit and a negative pressure generator connected to the adsorption port. The powder collection mechanism 50 also includes a collection container connected to the adsorption port, and the collection container is arranged on the support frame 12; the negative pressure generator is used to generate negative pressure under electric drive, and adsorb fine dust, fine powder, etc. floating within its adsorbable range through the second conduit and the adsorption port, and collect the fine dust and fine powder through the collection container connected to the adsorption port.

[0055] Among them, when the driving unit 14 drives the conveyor belt 11 to rotate along the preset direction, it drives the pressure rod in the initial state to rotate in the same direction to support the first working part 11a, so that the first working part 11a is arched, and the conveyor belt 11 continues to move. The pressure rod is separated from the first working part 11a and falls naturally under the action of gravity. The magnetic powder core 20 is separated from the first working part 11a. The blowing mechanism 40 is used to output airflow to the magnetic powder core 20 to remove the magnetic powder attached to the surface, and the powder collecting mechanism 50 is used to generate negative pressure to collect the falling magnetic powder.

[0056] Compared with the prior art, the conveying system of the magnetic powder core 20 from the press to the heat treatment equipment shown in this embodiment has the following advantages:

[0057] By arranging the conveyor belt 11 and the support frame 12, the pressing mechanism 30, the blowing mechanism 40 and the powder collecting mechanism 50, when the driving unit 14 drives the conveyor belt 11 to rotate in a preset direction, the pressing rod in the initial state will be driven to rotate in the same direction to support the first working part 11a, so that the first working part 11a is arched. The conveyor belt 11 continues to move, and the pressing rod is separated from the first working part 11a and falls naturally under the action of gravity. The magnetic powder core 20 is separated from the first working part 11a. The blowing mechanism 40 is used to output airflow to the magnetic powder core 20 to remove the powder adhering to the surface. Magnetic powder, the powder collecting mechanism 50 is used to generate negative pressure to collect the falling magnetic powder. The present invention can set a pressing mechanism 30 with a specific structure, so that the conveyor belt 11 can drive the pressing mechanism 30 to rotate during the rotation process to cyclically support and relax it, thereby effectively cleaning and collecting the magnetic dust attached to the surface of the magnetic powder core 20, thereby ensuring the cleanliness of the magnetic powder core 20. In the prior art, the conveying system of the magnetic powder type from the press to the heat treatment equipment still has the technical problem of not being able to effectively clean the surface of the magnetic powder core 20.

[0058] Example 2

[0059] The second embodiment of the present invention also provides a system for conveying the magnetic powder core 20 from the press to the heat treatment equipment. The structure of the conveying system shown in this embodiment is basically similar to that of the conveying system shown in the first embodiment, except that:

[0060] The pressing mechanism 30 further includes an angle sensor disposed on the rotating bracket 31 or the pressing rod.

[0061] Specifically, two angle sensors are provided, namely a first angle sensor and a second angle sensor. The first angle sensor is provided on the end surface of the first pressing rod 32 , and the second angle sensor is provided on the end surface of the second pressing rod 33 .

[0062] In this embodiment, when the first angle sensor detects that the first pressure rod 32 rotates to gradually increase the tilt angle, it will further determine whether the first angle sensor instantly generates a large angular acceleration. If a large angular acceleration is generated, it means that the first pressure rod 32 falls rapidly. When the first pressure rod 32 falls rapidly, the blowing mechanism 40 and the powder collecting mechanism 50 are controlled to move. The blowing mechanism 40 outputs a high-speed airflow to remove the magnetic powder attached to the surface of the magnetic powder core 20. The magnetic powder will be scattered in the air, and the powder collecting mechanism 50 generates negative pressure to collect the magnetic powder scattered in the air, thereby preventing the magnetic powder from adhering to the surface of the magnetic powder core 20 again, and the collected magnetic powder can also be recycled.

[0063] Example 3

[0064] See also Figure 6A third embodiment of the present invention provides a method for controlling a system for conveying magnetic powder cores from a press to a heat treatment device. The method is used to control the system for conveying magnetic powder cores from a press to a heat treatment device described in the above embodiment. The method comprises steps S1-S5:

[0065] Step S1, controlling the driving unit to move, driving the transmission roller to rotate and driving the conveyor belt to circulate along a preset direction;

[0066] Step S2: the conveyor belt cyclically rotates to drive the pressing mechanism to move in the same direction, and the pressing roller contacts the bottom surface of the first working part to support the first working part;

[0067] Step S3, the conveyor belt continues to rotate to separate the pressing roller from the first working portion, and the pressing roller naturally falls under the action of gravity, so that the magnetic powder core is separated from the first working portion;

[0068] Step S4, controlling the air blowing mechanism to blow air toward the magnetic powder core, so that the magnetic powder attached to the surface of the magnetic powder core moves with the air flow;

[0069] Step S5: controlling the powder collecting mechanism to generate negative pressure to collect the floating magnetic powder.

[0070] In this embodiment, when the angle sensor detects that the pressing roller in contact with the bottom surface of the first working part drops rapidly from the vertex position and increases the angular acceleration, the blowing mechanism and the powder collecting mechanism move successively.

[0071] Compared with the prior art, the control method for the conveying system of magnetic powder cores from a press to a heat treatment device shown in this embodiment has the following beneficial effects:

[0072] The conveying system is provided with a conveyor belt and a support frame, a pressure mechanism, a blowing mechanism and a powder collecting mechanism. When the driving unit drives the conveyor belt to rotate in a preset direction, the pressure rod in the initial state will be driven to rotate in the same direction to support the first working part, so that the first working part is arched, and the conveyor belt continues to move. The pressure rod is separated from the first working part and naturally falls down under the action of gravity. The magnetic powder core is separated from the first working part. The blowing mechanism is used to output airflow to the magnetic powder core to remove the magnetic powder attached to the surface. The powder collecting mechanism is used to generate negative pressure to collect the falling magnetic powder. The present invention can drive the pressure mechanism to rotate during the rotation process of the conveyor belt to cyclically support and relax it, so that the magnetic dust attached to the surface of the magnetic powder core can be effectively cleaned and the powder can be collected, thereby ensuring the cleanliness of the magnetic powder core. The existing magnetic powder type conveying system from the press to the heat treatment equipment still has the technical problem of not being able to effectively clean the surface of the magnetic powder core.
