Description

Technical Field

[0001] This invention relates to the field of mechanical equipment, and more particularly to a device for inserting magnets into an iron core and a magnet insertion system having the same. Background Technology

[0002] With social progress and development, China's use of magnets has surpassed the world average. When assembling motor rotors, magnet assembly is a crucial step. In the past, it was entirely done manually. First, the magnets had to be separated into individual pieces, then glued, and then workers would insert them one by one into the rotor core. Because the magnets are extremely strong, manual operation was not only labor-intensive but also dangerous. Slight negligence could cause the polarity to be reversed, affecting the assembly quality. Furthermore, manual insertion of magnets was inefficient and the workload of assembly personnel was heavy.

[0003] Currently, although some motor production processes utilize robotic arms to insert magnets into the rotor core, the high precision required during this process often leads to magnets failing to insert properly, affecting assembly quality. Furthermore, the limited number of robotic arms prevents the simultaneous insertion of multiple magnets, impacting efficiency. While some magnet insertion equipment can automate the process, manual feeding remains the most common method. Operators must be on standby, constantly replenishing the equipment with new magnets as soon as they are inserted, increasing labor intensity, disrupting the work cycle, and reducing efficiency.

[0004] Therefore, there is a need for a magnet insertion device and a magnet insertion system that can simultaneously insert multiple magnets with precise positioning, achieve automatic magnet feeding to reduce labor intensity, and have a magnet buffering function to effectively speed up the work cycle and improve work efficiency. Summary of the Invention

The number of buffer feeding mechanisms is the same as the number of pushing mechanisms and corresponds one-to-one. Each buffer feeding mechanism includes a buffer feeding bin with an open top and a hollow bottom, a baffle plate below the buffer feeding bin, and a buffer feeding cylinder for driving the baffle plate. The baffle plate has a first position that covers the bottom of the buffer feeding bin and a second position that avoids the bottom of the buffer feeding bin. The guide plate is provided with several pressing ports corresponding to the number of pushing mechanisms. The pressing ports are the same size as the magnets. A blocking component is provided above the pressing ports to restrict the falling of the magnets.

The buffer feeding cylinder drives the baffle plate to move to the second position, and the magnet falls into the pushing mechanism below. The pushing mechanism pushes the magnet above the pressing port. The pressing mechanism simultaneously applies pressure to several magnets and breaks the restriction of the blocking component. The magnet is pressed into the iron core on the loading platform through the pressing port.

The guide rods cooperate with the guide through holes to guide the pressing plate.

[0014] A magnet insertion system includes a production line with at least one of the aforementioned magnet insertion devices. A magnet feeding device and a magnet feeding robot are located on the side of the production line. The magnet core is placed on a tray on the production line. The magnet feeding robot removes a magnet from the magnet feeding device and places it into the magnet insertion device. The magnet core moves along the production line to the magnet insertion device, where it simultaneously inserts multiple magnets into the magnet core. The magnet-inserted magnet core then moves along the production line to the unloading position.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0043] See Figure 1-6. This invention provides a device for inserting magnets into iron cores, including a frame 110, a loading platform on the frame 110, a guide plate 120 above the loading platform, a pressing mechanism 130 above the guide plate 120, a plurality of pushing mechanisms 140 on the guide plate 120, a buffer feeding plate 160 above the pushing mechanisms 140, and a plurality of buffer feeding mechanisms 170 on the buffer feeding plate 160. The number of buffer feeding mechanisms 170 is the same as the number of pushing mechanisms 140 and corresponds one-to-one. Each buffer feeding mechanism 170 includes a buffer feeding bin 171 with an open top and a hollow bottom, and is located in the buffer feeding bin. The feeding hopper 171 has a baffle plate 172 below it and a buffer feeding cylinder 173 that drives the baffle plate 172 to move. The baffle plate 172 has a first position that blocks the bottom of the buffer feeding hopper 171 and a second position that avoids the bottom of the buffer feeding hopper 171. The guide plate 120 is provided with a plurality of pressing ports 121 corresponding to the number of pushing mechanisms 140. The pressing ports 121 are the same size as the magnets 7. A blocking component that restricts the falling of the magnets 7 is provided above the pressing ports 121. The pushing mechanism 140 is provided with a sensor to monitor the number of times the magnets 7 are loaded. Preferably, the number of pushing mechanisms 140 and pressing ports 121 is 8. Buffer feeding cylinder The 173 drive baffle 172 to move to the first position, and the magnet 7 is placed in the buffer feeding bin 171. The buffer feeding cylinder 173 drives the baffle 172 to move to the second position, and the magnet 7 falls into the pushing mechanism 140 below. The pushing mechanism 140 pushes the magnet 7 above the pressing port 121. The pressing mechanism 130 simultaneously applies pressure to several magnets 7 and breaks the restriction of the blocking components. The magnet 7 is pressed into the iron core on the loading platform through the pressing port 121. When the pushing mechanism 140 and the pressing mechanism 130 are performing the magnet insertion action, they can feed the buffer feeding bin 171, speeding up the overall magnet insertion cycle. This invention... With eight feeding mechanisms 140 feeding simultaneously, the pressing mechanism 130 can insert eight magnets 7 into the iron core at the same time, improving work efficiency. Through the cooperation of the guide plate 120, pressing port 121, feeding mechanism 140 and blocking component, the magnets 7 can be accurately positioned between the iron core and the pressing mechanism 130, which facilitates the pressing mechanism 130 to accurately press the magnets 7 into the iron core, improving the overall automation level, effectively reducing manpower and improving assembly quality. Furthermore, the buffer feeding mechanism 170 can realize the automatic feeding and buffering function of magnets 7, effectively reducing labor intensity and speeding up the magnet insertion cycle, thus improving work efficiency.

[0044] As one embodiment of the present invention, the buffer feeding bin 171 has multiple sizes and is detachable and replaceable. In the actual process of inserting magnets, a matching buffer feeding bin 171 can be selected and replaced according to the specific size of the magnet 7, thereby improving the applicability.

[0045] See Figure 4As an embodiment of the present invention, the pushing mechanism 140 includes a pushing bin 141 disposed on the guide plate 120, a pushing assembly, and a baffle 142 disposed on the edge of the pressing port 121 away from the pushing bin 141. The pushing assembly pushes the magnet 7 in the pushing bin 141 toward the baffle 142. Preferably, the pushing assembly includes a pushing cylinder 143 disposed on the frame 110 and a pushing rod 144 disposed at the movable end of the pushing cylinder 143. The pushing cylinder 143 extends and drives the pushing rod 144 to push the magnet 7 out of the pushing bin 141.

[0046] As one embodiment of the present invention, the blocking assembly includes a fixing block disposed on the frame 110, a pusher block 151 disposed above the pressure port 121, and a spring connecting the fixing block and the pusher block 151. Preferably, see [reference needed]. Figure 5 The push block 151 is provided with an inclined surface 152 that drives the push block 151 to move towards the fixed block. The push rod 144 pushes the magnet 7 towards the baffle 142. The push rod 144 and the baffle 142 fix the magnet 7 horizontally. At this time, the magnet 7 falls on the inclined surface 152 of the push block 151. Through the elastic force of the spring on the push block 151, the inclined surface 152 supports the magnet 7 and prevents the magnet 7 from falling into the pressing port 121 below. At this time, the magnet 7 is in a balanced state under the action of the push rod 144, the push block 151 and the baffle 142, waiting for the pressing mechanism 130 above to press down. After being subjected to pressure, the push block 151 moves away from the pressing port 121. When the pressure is released, the push block 151 returns to above the pressing port 121, which has an automatic reset function. The angle between the inclined surface 152 and the horizontal plane is 45-75°, preferably 50°, 60° or 70°.

[0047] See Figure 6 As an embodiment of the present invention, the pressing mechanism 130 includes a pressing cylinder mounting plate 131 mounted on the frame 110, a pressing cylinder 132 mounted on the pressing cylinder mounting plate 131, and a pressing plate 133 mounted on the movable end of the pressing cylinder 132. The pressing plate 133 drives the magnet 7 through the pressing port 121. Preferably, the pressing plate 133 is provided with a plurality of pressing blocks 134, and the positions of the pressing blocks 134 and the pressing ports 121 correspond one-to-one. The plurality of pressing blocks 134 press down at the same time, pressing the corresponding magnets 7 below through the pressing ports 21 into the iron core, effectively reducing the need for the same working process and mechanical actions, and improving work efficiency.

[0048] As an embodiment of the present invention, a plurality of guide rods 135 are provided between the frame 110 and the pressure cylinder mounting plate 131. The pressure plate 133 is provided with guide through holes that cooperate with the guide rods 135. The guide rods 135 cooperate with the guide through holes to guide the pressure plate 133, which can prevent the pressure plate 133 from shifting due to loosening between the components of the pressure mechanism 130. This would lead to uneven force on the magnets 7 below, and some magnets 7 would not be able to pass through the pressure port 121 smoothly due to the small force. Alternatively, the force on the magnet 7 may change from a single vertical downward force to a resultant force of both a vertical downward force and a horizontal force, causing the magnet 7 to break the original balance in the horizontal direction and shift. This would cause the magnet 7 to be misaligned with the pressure port 121 and unable to pass through the pressure port 121 smoothly.

[0049] In one embodiment of the present invention, the frame 110 is provided with a plurality of lifting cylinders 181 for driving the guide plate 120 to rise and fall, and a plurality of guide posts 182. The guide plate 120 is provided with guide holes corresponding to the guide posts 182. When it is necessary to supply magnets 7 to the pusher bin 141, the lifting cylinders 181 drive the guide plate 120 to rise to a position close to the buffer supply plate 160, the baffle plate 172 moves to the second position, the magnets 7 in the buffer supply bin 171 fall into the pusher bin 141, and the lifting cylinders 181 drive the guide plate 120 to fall to the initial position. The system continues to push the magnet. Preferably, the guide plate 120 is equipped with position sensors at the initial position and at the position adjacent to the buffer feed plate 160. Through the lifting function of the lifting cylinder 181, the distance between the buffer feed bin 171 and the push bin 141 is effectively pulled closer, reducing the stroke of the magnet 7 in the buffer feed bin 171 falling into the push bin 141. This reduces the inertia and impact of the magnet 7 falling into the push bin 141, lowers the risk of damage to the magnet 7 or the push bin 141, and improves the overall service life and safety of use.

[0050] During operation: The iron core is placed on the loading platform, and the magnet slots for inserting magnets are aligned one-to-one with the pressing ports 121. The buffer feeding cylinder 173 drives the baffle plate 172 to move to the first position. According to the iron core structure and requirements, the magnets 7 are placed into the corresponding buffer feeding bins 171. The lifting cylinder 181 drives the guide plate 120 to rise to a position near the buffer feeding plate 160. The buffer feeding cylinder 173 drives the baffle plate 172 to move to the second position, and the magnets 7 in the buffer feeding bins 171 fall into the pushing bins 141. The lifting cylinder 181 drives the guide plate 120 to descend to the initial position, and the pushing cylinder 143 extends, driving the pushing rod 144 to push the magnets 7 in the pushing bins 141 towards the baffle plate 142. The material rod 144, baffle 142, and push block 151 position the magnet 7 above the pressing port 121. The pressing cylinder 132 extends, driving the pressing plate 133 and pressing block 134 to move downward and apply vertical downward pressure to the magnet 7. The magnet 7 applies a pushing force to the inclined surface 152 on the push block 151, thereby compressing the spring and driving the push block 151 to move towards the spring. When the push block 151 is pushed away from above the pressing port 121, the magnet 7 passes through the pressing port 121 under pressure and is inserted into the iron core. The pressing cylinder 132 and push cylinder 143 retract, and the push block 151 returns to its original position under the action of the spring, reaching above the pressing port 121, and continues the magnet insertion action for the next iron core.

[0051] See Figure 7 This invention provides a magnet insertion system, including a production line 2. At least one magnet insertion device 1 is provided on the production line 2. A magnet feeding device 3 and a magnet feeding robot 4 are located on the side of the production line 2. Workers place iron cores onto a tray on the production line 2. The magnet feeding robot 4 removes magnets 7 from the magnet feeding device 3 and places them into the magnet insertion device 1. The iron core moves along the production line 2 to the magnet insertion device 1, where the magnet insertion device 1 simultaneously inserts multiple magnets 7 into the iron core, completing the magnet insertion process. Moving along production line 2 to the unloading position, preferably, production line 2 is also equipped with an iron core feeding device and an iron core feeding robot on the side. The iron core feeding robot takes out the iron core from the iron core feeding device and places it on the tray on production line 2. Automatic feeding replaces manual feeding by workers. The magnet feeding robot 4 and the iron core feeding robot realize the automatic feeding of magnets 7 and iron cores. The magnet insertion device 1 automatically inserts magnets, realizing the overall automated production, effectively reducing the labor intensity of operators and improving work efficiency.

[0052] As an embodiment of the present invention, the production line 2 is equipped with at least two weighing devices 5. One weighing device 5 is set at the feeding end of the iron core to obtain the weight of the empty iron core, and the other weighing device 5 is set at the unloading end of the iron core to obtain the weight of the iron core with attached magnets 7. By comparing the difference between the two weights of the iron core with the sum of the weights of all inserted magnets 7, if the two are the same, it is considered that the insertion of magnets is successful and the iron core is transferred to the next process. If the two are not the same, that is, the sum of the weights of all magnets 7 is greater than the difference between the two weights of the iron core, it is considered that the insertion of magnets has failed, that is, a certain magnet 7 has not been successfully inserted into the iron core. The staff is notified to manually inspect the iron core. This can promptly detect problems in the process of inserting magnets, prevent iron cores with failed insertion from being transferred to the next process, and improve the overall work efficiency.

[0053] As an embodiment of the present invention, the production line 2 is provided with at least one probe detection device 6. The probe detection device 6 is used to detect whether the magnet 7 is inserted into a designated position in the iron core. The probe detection device 6 and the weighing device 5 form a dual inspection of the iron core. When either the weighing device 5 or the probe detection device 6 fails, the other can continue to work, thereby improving the accuracy and reliability of the detection effect.

[0054] In one embodiment of the present invention, there are four iron core magnet insertion devices 1, which are arranged sequentially along the production line 2. The four iron core magnet insertion devices 1 insert magnets at four angles. There are four probe detection devices 6, which correspond one-to-one with the iron core magnet insertion devices 1. Let the four iron core magnet insertion devices 1 be A, B, C, and D, and the four probe detection devices 6 be a, b, c, and d. That is, a detects the position of the magnet insertion at A, b detects the position of the magnet insertion at B, c detects the position of the magnet insertion at C, and d detects the position of the magnet insertion at D. The four probe detection devices 6 perform their respective detection tasks. When a probe detection device 6 detects an abnormality, the staff can prioritize the inspection and repair of the corresponding iron core magnet insertion device 1, which can effectively reduce the troubleshooting time, improve the speed of fault repair, and thus improve the overall work efficiency.

[0055] See Figure 8 As an embodiment of the present invention, the probe detection device 6 includes a detection bracket 61 set on the production line 2. The detection bracket 61 is provided with a plurality of probe sensors 62 and a probe cylinder 63 that drives the probe sensors 62 to rise and fall. The probe cylinder 63 drives the probe sensors 62 to fall. The probe sensors 62 detect whether there is a magnet 7 in the iron core and feed back a detection signal. One probe detects one magnet 7, which can improve the accuracy of detection.

[0056] As an embodiment of the present invention, the probe detection device 6 further includes a positioning sensor 65 disposed on the production line 2 and a positioning rod movably disposed on the production line 2. Preferably, the production line 2 is provided with a rotating shaft, and the positioning rod rotates around the rotating shaft between a locked position and an unlocked position. The tray is provided with a positioning groove that cooperates with the positioning rod. When the positioning sensor 65 detects the tray, the production line 2 stops moving, and the positioning rod rotates to the locked position to lock with the positioning groove on the tray, preventing the iron core on the tray from shifting. The probe sensor 62 then detects the magnet 7 on the iron core, which can improve the accuracy of the detection.

[0057] See Figure 9 As an embodiment of the present invention, the magnet feeding robot 4 includes a robot frame 47, on which are provided a first gripper 41, a first gripper cylinder 42 for driving the opening and closing of the first gripper 41, a second gripper 43, and a second gripper cylinder 44 for driving the opening and closing of the second gripper 43. The opening and closing direction of the first gripper 41 is perpendicular to the opening and closing direction of the second gripper 43. Both ends of the first gripper 41 are provided with first clamping plates 45, and both ends of the second gripper 43 are provided with second clamping plates 46. The two first clamping plates 45 and the two second clamping plates 46 respectively clamp the magnet 7 on the iron core feeding device from four directions. To improve the stability of gripping; preferably, the length of the first clamping plate 45 is greater than the length of the second clamping plate 46. The first clamping plate 45 contacts the magnet 7 first, and the second clamping plate 46 contacts the magnet 7 later. When gripping the magnet 7, the first gripper cylinder 42 is controlled to drive the first gripper 41 to close the two first clamping plates 45. The two first clamping plates 45 can arrange the magnet 7 and arrange several magnets 7 into a row. Then, the second gripper cylinder 44 is controlled to drive the second gripper 43 to close the two second clamping plates 46. The two second clamping plates 46 fix several magnets 7 in the vertical direction, which can further improve the stability of gripping.

[0058] During operation, the core feeding robot removes the core from the core feeding device and places it on a tray on the production line 2. The weighing device 5 at the loading end weighs and records the weight of the core. The magnet feeding robot 4 removes magnets 7 from the magnet feeding device 3 and places them into the four core magnet insertion devices 1. The core follows the production line 2 and first moves to the first core magnet insertion device 1. The first core magnet insertion device 1 inserts eight magnets 7 into the core simultaneously at a first angle. After the core has been magnetized, it continues to move sequentially to the second, third, and fourth core magnet insertion devices 1. The second core magnet insertion device 1 inserts magnets 7 into the core at a second angle. Simultaneously, eight magnets 7 are inserted into the iron core. The third iron core magnet insertion device 1 inserts eight magnets 7 into the iron core at a third angle. The fourth iron core magnet insertion device 1 inserts eight magnets 7 into the iron core at a fourth angle. The iron core with magnets inserted moves sequentially along the production line 2 to four probe detection devices 6. The four probe detection devices 6 detect the corresponding magnets 7 on the iron core. If an abnormality is detected, an alarm is triggered. If no abnormality is detected, the iron core moves along the production line 2 to the weighing device 5 at the unloading end for weighing and recording. If an abnormality is detected, an alarm is triggered. If no abnormality is detected, the unloading robot grabs the iron core to the next process.

[0059] In summary, this invention provides a magnet insertion device for an iron core and a magnet insertion system thereon. Eight pushing mechanisms 140 simultaneously feed the magnets, and the pressing mechanism 130 can simultaneously insert eight magnets 7 into the iron core, improving work efficiency. Through the cooperation of the guide plate 120, the pressing port 121, the pushing mechanism 140, and the blocking component, the magnets 7 can be precisely positioned between the iron core and the pressing mechanism 130, facilitating the pressing mechanism 130 to accurately press the magnets 7 into the iron core, improving the overall automation level, effectively reducing manpower, and improving assembly quality. Furthermore, the buffer feeding mechanism 170 enables automatic feeding of the magnets 7. The magnetic steel 7 buffer function effectively reduces labor intensity and speeds up the insertion cycle, improving work efficiency; it can select a matching buffer feeding bin 171 for replacement according to the specific size of the magnetic steel 7, expanding its applicability; several pressing blocks 134 press down simultaneously, pressing their respective corresponding magnetic steel 7 through the pressing port 21 into the iron core, effectively reducing the need for repetitive workflows and mechanical actions, thus improving work efficiency; the lifting function of the lifting cylinder 181 effectively shortens the distance between the buffer feeding bin 171 and the pushing bin 141, reducing the travel distance of the magnetic steel 7 in the buffer feeding bin 171 as it falls into the pushing bin 141. This reduces the inertia and impact of the magnet 7 falling into the pusher hopper 141, lowering the risk of damage to the magnet 7 or the pusher hopper 141, and improving the overall service life and safety. The magnet feeding robot 4 and the iron core feeding robot automatically feed the magnet 7 and the iron core, while the iron core insertion magnet device 1 automatically inserts the magnets, achieving overall automated production, effectively reducing the labor intensity of operators and improving work efficiency. The weighing device 5 and the probe detection device 6 form a dual inspection of the iron core, which can promptly detect problems during the magnet insertion process, preventing failed magnet insertion cores from being transferred to the next process, thus improving the overall efficiency. The system improves work efficiency, and when one of the weighing device 5 or the probe detection device 6 fails, the other can continue to work, improving the accuracy and reliability of the detection effect; the positioning rod and the positioning groove on the tray cooperate with each other to prevent the iron core on the tray from shifting, thus improving the accuracy of the detection; firstly, the two first clamping plates 45 are controlled to contact the magnets 7, which can organize the magnets 7 and arrange several magnets 7 into a row, and then the two second clamping plates 46 are controlled to contact the magnets 7. The two first clamping plates 45 and the two second clamping plates 46 clamp the magnets 7 on the iron core feeding device from four directions, improving the stability of the clamping.
