Description

Technical Field

[0001] The present invention relates to the technical field of motor production equipment, and in particular to an automatic feeding device for motor rotor shafts. Background Art

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction, or converts electrical energy in one form into electrical energy in another form. It consists of a stator, a rotor, and other accessories. The rotor is used to cut the rotating magnetic field of the stator to generate induced electromotive force and current, and form an electromagnetic torque to make the motor rotate. Most of the existing motor rotor structures are composed of an armature, a coil, a rotor shaft, and other accessories. As the transmission structure, the rotor shaft is the core structure connecting the rotor components. It is usually made of metal materials such as steel or aluminum alloy, mainly used to support and connect other components on the rotor, and allow the rotor to rotate in the axial direction, playing the role of supporting and transmitting power. Since the rotor on the rotor shaft is formed by die-casting, grooves are generally provided on the rotor shaft, and the grooves can increase the connection strength between the die-cast rotor and the rotor shaft.

[0003] During the mass production process of motor rotors, a large number of processed rotor shafts will be stored in the storage bin. When manufacturing motor rotors, the rotor shafts need to be taken out from the storage bin one by one and transported to the next workbench and wait for die-casting processing. At present, a pushing mechanism is mainly used to apply a thrust to the rotor shafts in the storage bin to discharge the rotor shafts from the storage bin one by one onto the transportation mechanism and transport them to the next workbench through the transportation components. However, since the rotor shafts are stacked together in the storage bin without being partitioned one by one, and the diameter of the rotor shafts is small, when the pushing mechanism pushes the rotor shafts, it is easy to push multiple rotor shafts at one time, resulting in multiple rotor shafts being discharged from the storage bin at the same time. That is, the accuracy of taking the rotor shafts is relatively low, increasing the risk of unqualified motor rotors produced, thereby increasing the unqualified rate of motor rotors in production and processing. Therefore, it needs to be improved. Summary of the Invention

[0004] In order to overcome the deficiency of relatively low accuracy in taking rotor shafts in the prior art, the present invention provides an automatic feeding device for motor rotor shafts, which improves the accuracy of taking rotor shafts and reduces the unqualified rate of motor rotors in production and processing.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic feeding device for a motor rotor shaft, comprising a fixed frame, a material storage mechanism and a material taking mechanism arranged on the fixed frame. The material storage mechanism includes a material storage rack fixedly connected to the fixed frame, and a material storage bin, a discharging part, a first ejecting component, a lifting table and a first lifting driving part arranged on the material storage rack. The height of the discharging part is higher than the outlet end of the material storage bin. The lifting table is arranged between the discharging part and the outlet end. The material storage rack has a discharging position corresponding to the discharging part. The lifting table has a first position corresponding to the outlet end and a second position corresponding to the discharging position. The first lifting driving part drives the lifting table to switch between the first position and the second position so that the rotor shaft on the lifting table enters the discharging position. The material taking mechanism is arranged on one side of the discharging position. The first ejecting component is arranged on the other side of the discharging position and is used to push the rotor shaft at the discharging position to the material taking mechanism.

[0007] In the above technical solution, when using this device for material taking and feeding, a large number of rotor shafts are stacked in the material storage bin. Under the action of the gravity of the rotor shafts, other rotor shafts will exert a thrust on the rotor shaft at the outlet, so that the rotor shaft moves out of the material storage bin through the outlet at the outlet end. Initially, the lifting table is located at the first position corresponding to the outlet end. One of the rotor shafts moving out of the outlet will move onto the lifting table, and the other rotor shafts are outside the lifting table. The height of the discharging part is higher than the outlet end. The discharging position corresponds to the discharging part. The first position corresponds to the outlet end, and the second position corresponds to the discharging position. Therefore, the first position is higher than the second position. Then, the first lifting driving part drives the lifting table to rise so that it switches from the first position to the second position. The second position corresponds to the discharging position, so that the rotor shaft on the lifting table enters the discharging position. Then, the first ejecting component pushes the rotor shaft in the discharging position to the material taking mechanism. The material taking mechanism transports the rotor shaft to the next processing position, that is, one rotor shaft is taken out from the material storage mechanism. Then, the first lifting driving part drives the lifting table to descend so that it switches from the second position to the first position. Since the lifting table is in an empty state at this time, under the thrust action between the rotor shafts, another rotor shaft at the outlet end moves onto the empty lifting table. The first lifting driving part drives the lifting table to rise again so that it switches from the first position to the second position, making the rotor shaft on the lifting table enter the discharging position. The first ejecting component pushes the rotor shaft in the discharging position to the material taking mechanism again. In this way, the cycle is repeated, and the rotor shafts are taken out one by one. Among them, by switching the position of the lifting table, the rotor shafts are transported to the discharging position one by one, and then the first ejecting component pushes the rotor shafts out of the material storage mechanism one by one, ensuring that the first ejecting component only exerts a thrust on one rotor shaft each time to push it out of the material storage mechanism, improving the accuracy of taking and using the rotor shafts, reducing the risk of unqualified motor rotors produced, and thus reducing the unqualified rate of motor rotors in production and processing.

[0008] Preferably, the lifting platform is provided with a support area, the support area is open on a side facing the outlet end, and the bottom height of the support area decreases from a side close to the outlet end to a side away from the outlet end.

[0009] In the structure, the side of the support area facing the outlet end is open, so that when the lifting platform is in the first position, the rotor shaft enters the support area through the side of the support area facing the outlet end, and the bottom surface height of the support area decreases from the side close to the outlet end to the side far from the outlet end, so that the rotor shaft moves from the side of the support area close to the outlet end to the side of the support area far from the outlet end under the action of its own gravity, reducing the risk of the rotor shaft falling back to the outlet end from the lifting platform due to the rotor shaft being at the edge of the support area, reducing the risk of the lifting platform being empty, preventing the lifting platform from being empty and affecting the equipment's material collection efficiency for the rotor shaft, and improving the stability of the equipment.

[0010] Preferably, the material storage rack is provided with a positioning side wall, and the lifting platform is arranged close to the positioning side wall so that the rotor shaft on the supporting area is close to the positioning side wall.

[0011] In the structure, the lifting platform is close to the positioning side wall so that the rotor shaft on the supporting area is close to the positioning side wall. The positioning side wall hinders the rotor shaft from moving in the direction away from the outlet end, reducing the risk of the rotor shaft continuing to move in the direction away from the outlet end after moving to the supporting area and falling from the lifting platform, that is, reducing the risk of the lifting platform being empty, preventing the lifting platform from being empty and affecting the equipment's material collection efficiency for the rotor shaft, and improving the stability of the equipment's use.

[0012] Preferably, the width of the support area is L 1 , the diameter of the rotor shaft is D, 0.5D<L 1 <1.5D.

[0013] In the structure, the width L of the support area 1 When the width of the support area is greater than 0.5D, a rotor shaft can be moved and placed relatively stably in the support area, which reduces the risk of the rotor shaft falling or being unable to enter the support area, prevents the lifting platform from being empty and affecting the equipment's efficiency in taking the rotor shaft, and improves the stability of the equipment. At the same time, the width of the support area L 1 Less than 1.5D reduces the risk of two or more rotor shafts being located on the support area, prevents the lifting platform from transporting two or more rotor shafts to the discharge position, ensures that the first ejection component applies thrust to only one rotor shaft at a time to eject it from the storage mechanism, improves the accuracy of rotor shaft retrieval, reduces the risk of unqualified motor rotors produced, and thereby reduces the unqualified rate of motor rotors during production and processing.

[0014] Preferably, the stock rack is provided with a discharge table corresponding to the discharge position. The discharge table and the outlet end are arranged on both sides of the support area. The side of the support area facing the discharge table is open. When the lifting table is in the second position, the support area is higher than the discharge table, so that the rotor shaft in the support area can enter the discharge table.

[0015] In the above structure, the setting of the discharge table enables the rotor shaft to accurately enter the discharge position, so that the first ejection component corresponding to the discharge position can accurately eject the rotor shaft from the stock mechanism, preventing the first ejection component from being unable to eject the rotor shaft due to the deviation of the rotor shaft from the discharge position, reducing the risk of affecting the subsequent extraction and processing of the rotor shaft due to the inability to eject the rotor shaft, and improving the stability of equipment use.

[0016] Preferably, the outlet end is provided with a buffer table. The buffer table is located between the lifting table and the outlet end and is liftably arranged on the stock rack. The buffer table has a buffer area. The first side of the buffer area facing the outlet end and the second side facing the lifting table are both open. The bottom surface height of the buffer area decreases from the first side to the second side. The buffer table has a third position and a fourth position. When the buffer table is in the third position, the bottom surface height of the first side is lower than the bottom surface height of the outlet end. When the buffer table is in the fourth position and the lifting table is in the first position, the bottom surface height of the second side is higher than the bottom surface height of the lifting table. The stock rack is provided with a second lifting drive member for driving the buffer table to switch between the third position and the fourth position.

[0017] In the described structure, when the rotor shaft is discharged from the storage bin outside the outlet end of the outlet, when the buffer table is in the third position, the bottom surface height of the first side is lower than the height of the outlet end, wherein the bottom surface height of the buffer area decreases from the first side to the second side, so that the rotor shafts of multiple outlet ends move from the outlet end onto the buffer area, and after reaching the buffer area, move from the first side of the buffer area to the second side until the buffer area is covered. Then, the second lifting drive member drives the buffer table to switch from the third position to the fourth position. When the buffer table is in the fourth position, the bottom surface height of the second side is higher than the bottom surface height when the lifting table is in the first position, so that the rotor shaft closest to the lifting table on the buffer area moves onto the lifting table in the first position. Then, the first lifting drive member drives the lifting table to switch from the first position to the second position to transport the rotor shaft to the discharging position. Finally, the first ejecting assembly ejects the rotor shaft out of the storage mechanism. Then, the first lifting drive member drives the empty lifting table to switch from the second position to the first position, and another rotor shaft on the buffer area moves onto the lifting table again. Then, when the lifting table transports this rotor shaft to the discharging position, the rotor shaft is ejected by the first ejecting assembly, and so on in a cycle until the last rotor shaft on the buffer table moves onto the empty lifting table. At this time, while the first lifting drive assembly drives the lifting table to switch positions, the second lifting drive assembly drives the empty buffer table to switch from the fourth position to the third position, so that the rotor shaft at the outlet end enters the buffer area again. After the buffer area is covered with rotor shafts, the second lifting drive member drives the buffer table to switch from the third position to the fourth position, and so on in a cycle to realize the sequential ejection of the rotor shafts from the storage mechanism. Among them, the use of the buffer table enables multiple rotor shafts to be transported from the third position to the fourth position and then enter the lifting table one by one, thereby realizing the synchronous movement of multiple rotor shafts during part of the time, and at the same time shortening the distance required between the first position and the second position of the lifting table, that is, shortening the time required for the lifting table to switch from the first position to the second position. Moreover, the switching of the position of the lifting table and the switching of the position of the buffer table can be carried out synchronously, thereby shortening the time required to take out a large number of rotor shafts and improving the efficiency of the equipment for taking out the rotor shafts.

[0018] Preferably, the buffer area is arranged closely adjacent to the lifting table so that when the buffer table is in the third position and the lifting table is in the second position, the rotor shafts in the buffer area are closely adjacent to the side wall of the lifting table.

[0019] In the described structure, the buffer area is arranged closely adjacent to the lifting table so that when the buffer table is in the third position, the rotor shafts in the buffer area are closely adjacent to the side wall of the lifting table. The side wall hinders the rotor shaft from moving away from the outlet end, reducing the risk that the rotor shaft continues to move away from the outlet end after moving to the buffer area and falls off the buffer area and cannot enter the lifting table, that is, reducing the risk of the lifting table being empty, preventing the lifting table from being empty and affecting the material taking efficiency of the equipment for the rotor shafts, and improving the stability of the equipment operation.

[0020] Preferably, the width of the buffer is L 2 , the diameter of the rotor shaft is D, and 2D ≤ L 2 .

[0021] In the said structure, the width L of the buffer 2 is greater than or equal to 2D, so that at least two rotor shafts can be placed in the buffer, ensuring that there are at least two rotor shafts in the buffer each time the buffer table switches from the third position to the fourth position, reducing the risk that the buffer table transports only one rotor shaft each time, which may lead to a decrease in the picking efficiency of the equipment for the rotor shaft, and improving the stability of the equipment operation.

[0022] Preferably, the storage rack is provided with a first sensor for detecting whether there is a rotor shaft at the discharging position.

[0023] In the said structure, detecting whether there is a rotor shaft at the discharging position by the first sensor can feed back to the first ejecting assembly, reducing the risk of the first ejecting assembly doing useless work, thereby reducing the energy consumption of the equipment. At the same time, the first sensor can record the number of rotor shafts taken out by detecting whether there is a rotor shaft at the discharging position. When the number of rotor shafts reaches the processing requirement, the first sensor feeds the data back to the first lifting driving member to suspend the taking of rotor shafts, ensuring that the number of rotor shafts taken out meets the processing requirement, without manual recording, reducing the risk that inaccurate number of rotor shafts affects subsequent processing, and improving the convenience and stability of equipment operation.

[0024] Preferably, the bottom surface height of the storage bin decreases from the side far away from the outlet end to the side close to the outlet end.

[0025] In the said structure, the bottom surface height of the storage bin decreases from the side far away from the outlet end to the side close to the outlet end, so that the rotor shafts move towards the direction close to the outlet end under the action of their own gravity and exert a thrust on the rotor shafts at the outlet end, ensuring that the rotor shafts are discharged one by one from the outlet of the outlet end to the outside of the storage bin, preventing the risk that the rotor shafts cannot be discharged from the outlet of the storage bin due to the force exerted between the rotor shafts being too small to overcome the friction force they bear, reducing the risk that the rotor shafts cannot be discharged from the storage bin and affecting the taking of rotor shafts, and improving the stability of equipment operation.

[0026] Preferably, the material picking mechanism includes a mobile frame slidably connected to the fixed frame, a mobile mechanism for driving the mobile frame to translate, and a vacuum negative pressure component, a second ejection component and at least one hollow tube arranged on the mobile frame, one end of the hollow tube faces the discharge position, the second ejection component is arranged at the other end of the hollow tube and is used to eject the rotor shaft in the hollow tube, and the vacuum negative pressure component is connected to the inner cavity of the hollow tube to generate negative pressure in the inner cavity.

[0027] In the structure, when the lifting platform switches from the first position to the second position, so that a corresponding rotor shaft is in the discharge position, the moving mechanism drives the moving frame to translate so that one end of the hollow tube is facing the discharge position. At this time, the first ejection component applies a thrust to the rotor shaft to make it move in the direction close to the hollow tube, and at the same time, the vacuum negative pressure component generates a negative pressure in the inner cavity of the hollow tube so that the inner cavity of the hollow tube generates a suction force on the rotor shaft due to the pressure difference, thereby causing the rotor shaft to move as a whole from the discharge position to the inner cavity of the hollow tube. If there are multiple hollow tubes, the moving mechanism drives the moving frame to translate so that another hollow tube is facing the discharge position, and this cycle is used to realize the removal of the rotor shafts one by one. Until all hollow tubes have a rotor shaft, the moving mechanism drives the moving frame to translate to the next workbench for processing the rotor shaft, and then the second ejection component ejects the rotor shaft in the hollow tube, thereby realizing the removal and transportation of the rotor shaft. A vacuum negative pressure component is used to generate negative pressure in the inner cavity of the hollow tube, thereby increasing the probability that the rotor shaft enters the hollow tube completely and preventing the risk that a part of the rotor shaft does not enter the hollow tube due to a small thrust applied by the first ejection component to the rotor shaft. This reduces the risk of the hollow tube being empty and affecting the transportation efficiency of the rotor shaft and the risk of the rotor shaft failing to be removed smoothly and affecting subsequent processing, thereby improving the stability of equipment use.

[0028] Preferably, a detection mechanism for detecting whether the rotor shaft is reversed is provided between the material storage mechanism and the material taking mechanism, and a rotor shaft recovery box is provided below the detection mechanism.

[0029] In the structure, the groove is formed on the circumferential side wall at one end of the rotor shaft, that is, the groove deviates from the middle position in the length direction of the rotor shaft. Therefore, in order to enable the components to be accurately installed at the corresponding positions when the rotor shaft is subsequently processed, when the rotor shaft is taken out from the storage bin, the direction of the end of the rotor shaft with the groove must be the same and the rotor shaft must be in the positive direction, that is, the direction of the rotor shaft taken by the material taking mechanism must be consistent and positive. The groove for the positive direction of the rotor shaft is located at one end of the rotor shaft close to the storage rack, and the groove for the reverse direction of the rotor shaft is located at one end of the rotor shaft away from the storage rack. A detection mechanism is installed in the process of transferring the rotor shaft from the storage mechanism to the picking mechanism. The detection mechanism detects the direction of the rotor shaft. If the rotor shaft direction is positive, that is, the detection result is qualified, the rotor shaft continues to be transferred to the picking mechanism. If the rotor shaft direction is reverse, that is, the detection result is unqualified, the rotor shaft will be taken out from the detection mechanism and placed in the rotor shaft recovery box below, that is, the rotor shaft with the wrong direction is excluded before the rotor shaft enters the picking mechanism, thereby reducing the risk of producing unqualified motor rotors due to incorrect rotor shaft direction, and reducing the unqualified rate in the production and processing of motor rotors.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. It ensures that the first ejection component applies thrust to only one rotor shaft at a time to eject it from the storage mechanism, thereby improving the accuracy of taking the rotor shaft and reducing the risk of unqualified motor rotors produced, thereby reducing the unqualified rate of motor rotors in production and processing;

[0032] 2. Reduce the risk of the lifting platform being empty, prevent the lifting platform from being empty and affecting the equipment's material collection efficiency for the rotor shaft, and improve the stability of equipment use;

[0033] 3. The setting of the discharge table prevents the first ejection assembly from being unable to eject the rotor shaft due to the rotor shaft deviating from the discharge position, reduces the risk of affecting the subsequent removal and processing of the rotor shaft due to the inability to be ejected, and improves the stability of equipment use;

[0034] 4. The setting of the buffer table shortens the time required to remove a large number of rotor shafts and improves the efficiency of the equipment in removing rotor shafts;

[0035] 5. The setting of the detection mechanism reduces the risk of producing unqualified motor rotors due to incorrect rotor shaft orientation, and reduces the unqualified rate in the production and processing of motor rotors. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Embodiment 1:

[0057] Embodiment 1 of the present application discloses an automatic feeding device for a motor rotor shaft.

[0058] Referring to Figure 1 、 Figure 2 and Figure 3 , an automatic feeding device for a motor rotor shaft 1 includes a fixing frame 2, a storage mechanism 3 and a material taking mechanism 4 installed on the fixing frame 2. The storage mechanism 3 includes a storage rack 31 fixedly connected to the fixing frame 2, and a storage bin 34, a discharging part 32, a first ejecting component 33, a lifting table 35 and a first lifting driving part installed on the storage rack 31.

[0059] Referring to Figure 1 、 Figure 2 and Figure 3 , the discharging part 32 is a discharging hole 321 opened on the storage rack 31 and corresponding to the material taking mechanism 4. The storage rack 31 has a discharging position corresponding to the discharging hole 321. The discharging position is the position where the first ejecting component 33 in the storage rack 31 can push the rotor shaft 1 out of the storage mechanism 3 through the discharging hole 321. The height of the discharging position is higher than the bottom surface height of the outlet end 343 of the storage bin 34. The lifting table 35 is located between the discharging position and the outlet end 343. The lifting table 35 has a first position corresponding to the outlet end 343 and a second position corresponding to the discharging position. The first lifting driving part drives the lifting table 35 to switch between the first position and the second position so that the rotor shaft 1 on the lifting table 35 enters the discharging position. The first lifting driving part uses a conventional driving cylinder. One end of the piston rod of the first lifting driving part is fixedly connected to the lifting table 35, and the other end is fixedly connected to the storage rack 31.

[0060] Referring to Figure 1 、 Figure 2 and Figure 3 , the material taking mechanism 4 is located on one side of the discharging position. The first ejecting component 33 is located on the other side of the discharging position and is used to push the rotor shaft 1 in the discharging position to the material taking mechanism 4. The first ejecting component 33 includes a first telescopic driving part 331 and an ejecting shaft. The ejecting shaft is installed at the telescopic end of the first telescopic driving part 331. The first telescopic driving part 331 uses a conventional driving cylinder. One end of the piston rod of the first telescopic driving part 331 is connected to the ejecting shaft, and the other end is fixedly connected to the storage rack 31.

[0061] The implementation principle of the automatic feeding device for a motor rotor shaft in Embodiment 1 of the present application is as follows:

[0062] When using this device for material picking and feeding, a large number of rotor shafts 1 are stacked in the storage bin 34. Under the gravitational force of the rotor shaft 1, other rotor shafts 1 will exert a thrust on the rotor shaft 1 at the outlet end 343, causing the rotor shaft 1 to move out of the storage bin 34 through the outlet of the outlet end 343. Initially, the lifting table 35 is located at the first position corresponding to the outlet end 343. One of the rotor shafts 1 moving out of the outlet will move onto the lifting table 35, and the other rotor shafts 1 are outside the lifting table 35. The height of the discharging position is higher than that of the outlet end 343. The first position corresponds to the outlet end 343, and the second position corresponds to the discharging position. Therefore, the first position is higher than the second position. After that, the first lifting driving member drives the lifting table 35 to rise, causing it to switch from the first position to the second position. The second position corresponds to the discharging position, so that the rotor shaft 1 on the lifting table 35 enters the discharging position. Then, the first ejecting assembly 33 pushes the rotor shaft 1 in the discharging position through the discharging hole 321 to the material picking mechanism 4, that is, the first telescopic driving member 331 extends, causing the ejecting shaft to slide towards the rotor shaft 1 located in the discharging position, so that the ejecting shaft exerts a thrust on the rotor shaft 1 to slide towards the material picking mechanism 4, thereby causing the rotor shaft 1 to be pushed onto the material picking mechanism 4. The material picking mechanism 4 transports the rotor shaft 1 to the next processing position, that is, it realizes taking out one rotor shaft 1 from the storage mechanism 3. After that, the first lifting driving member drives the lifting table 35 to descend, causing it to switch from the second position to the first position. Since the lifting table 35 is in an empty state at this time, under the thrust between the rotor shafts 1, another rotor shaft 1 at the outlet end 343 moves onto the empty lifting table 35. The first lifting driving member drives the lifting table 35 to rise again, causing it to switch from the first position to the second position, so that the rotor shaft 1 on the lifting table 35 enters the discharging position. The first ejecting assembly 33 pushes the rotor shaft 1 in the discharging position to the material picking mechanism 4 again, and so on in a cycle, thereby realizing the sequential taking out of the rotor shafts 1. Among them, by switching the position of the lifting table 35, the rotor shafts 1 are sequentially transported to the discharging position, and then the first ejecting assembly 33 pushes the rotor shafts 1 out of the storage mechanism 3 one by one, ensuring that the first ejecting assembly 33 only exerts a thrust on one rotor shaft 1 each time to eject it from the storage mechanism 3, improving the accuracy of taking and using the rotor shaft 1, reducing the risk of unqualified motor rotors produced, and thus reducing the unqualified rate of motor rotors in production and processing.

[0063] Refer to Figure 2 and Figure 3, To reduce the risk of the lifting table 35 being unloaded, the lifting table 35 has a support area 351. The side of the support area 351 facing the outlet end 343 is arranged in an open manner, and the bottom surface height of the support area 351 decreases from the side close to the outlet end 343 to the side far from the outlet end 343. Among them, the side of the support area 351 facing the outlet end 343 is arranged in an open manner, so that when the lifting table 35 is in the first position, the rotor shaft 1 enters the support area 351 through the side of the support area 351 facing the outlet end 343. And the bottom surface height of the support area 351 decreases from the side close to the outlet end 343 to the side far from the outlet end 343, so that the rotor shaft 1 moves from the side of the support area 351 close to the outlet end 343 to the side of the support area 351 far from the outlet end 343 under its own gravity, reducing the risk of the rotor shaft 1 falling back to the outlet end 343 from the lifting table 35 due to the rotor shaft 1 being at the edge of the support area 351. In this way, the risk of the lifting table 35 being unloaded is reduced, preventing the lifting table 35 from being unloaded and affecting the material taking efficiency of the equipment for the rotor shaft 1, and improving the stability of equipment use.

[0064] Refer to Figure 2 and Figure 3 , Further, the storage rack 31 has a positioning side wall 311. The side of the lifting table 35 far from the outlet end 343 is arranged closely against the positioning side wall 311, so that the rotor shaft 1 on the support area 351 is closely against the positioning side wall 311. Among them, the positioning side wall 311 hinders the movement of the rotor shaft 1 in the direction away from the outlet end 343, reducing the risk of the rotor shaft 1 falling from the lifting table 35 after moving to the support area 351 and continuing to move in the direction away from the outlet end 343, that is, reducing the risk of the lifting table 35 being unloaded, preventing the lifting table 35 from being unloaded and affecting the material taking efficiency of the equipment for the rotor shaft 1, and improving the stability of equipment use.

[0065] Refer to Figure 2 and Figure 3 , And to further reduce the risk of the lifting table 35 being unloaded, the diameter of the rotor shaft 1 is D, and the width of the support area 351 is L 1 , 0.5D < L 1 < 1.5D, the width L of the support area 351 1 is greater than 0.5D, so that the width of the support area 351 can enable a rotor shaft 1 to move and be placed in the support area 351 more stably, reducing the risk of the rotor shaft 1 falling or not being able to enter the support area 351, preventing the lifting table 35 from being unloaded and affecting the material taking efficiency of the equipment for the rotor shaft 1, and improving the stability of equipment use; at the same time, the width L of the support area 351 1Less than 1.5D reduces the risk of two or more rotor shafts 1 being located on the support area 351, prevents the lifting platform 35 from transporting two or more rotor shafts 1 to the discharge position, ensures that the first ejection component 33 applies thrust to only one rotor shaft 1 at a time to eject it from the storage mechanism 3, improves the accuracy of taking the rotor shaft 1, reduces the risk of unqualified motor rotors produced, and thereby reduces the unqualified rate of motor rotors during production and processing.

[0066] Preferably, 1.1D<L 1 <1.4D, width L of support area 351 1 The width L of the support area 351 is greater than 1.1D, which further allows a rotor shaft 1 to move and be placed in the support area 351 more stably, further reducing the risk of the rotor shaft 1 falling or being unable to enter the support area 351, preventing the lifting platform 35 from being empty and affecting the material collection efficiency of the equipment for the rotor shaft 1, and improving the stability of the equipment. At the same time, the width L of the support area 351 is 1 Less than 1.4D further reduces the risk of two or more rotor shafts 1 being located on the support area 351, prevents the lifting platform 35 from transporting two or more rotor shafts 1 to the discharge position, ensures that the first ejection component 33 applies thrust to only one rotor shaft 1 at a time to eject it from the storage mechanism 3, improves the accuracy of taking the rotor shaft 1, reduces the risk of unqualified motor rotors produced, and thereby reduces the unqualified rate of motor rotors during production and processing.

[0067] Reference Figure 2 and Figure 3In order to reduce the energy consumption of the equipment, the storage rack 31 is equipped with a first sensor 314 for detecting whether there is a rotor shaft 1 at the discharge position. The first sensor 314 adopts a conventional laser sensor. The first sensor 314 includes a first transmitting end and a first receiving end. The first transmitting end and the first receiving end are respectively located on both sides of the discharge position, that is, when the rotor shaft 1 is not at the discharge position, the first receiving end will receive the laser emitted by the first transmitting end. When the rotor shaft 1 is at the discharge position, the rotor shaft 1 will block the laser emitted by the first transmitting end, so that the first sensor 314 cannot receive the laser, so that the first sensor 314 can judge whether there is a rotor shaft 1 at the discharge position, and can record the number of rotor shafts 1 taken out by the number of times it is blocked. The first sensor 314 can detect whether there is a rotor shaft 1 at the discharge position, which can provide feedback to the first ejection assembly 33, reduce the risk of the first ejection assembly 33 doing useless work, and thus reduce the energy consumption of the equipment. At the same time, the sensor can record the number of rotor shafts 1 taken out by detecting whether there is a rotor shaft 1 at the discharge position. When the number of rotor shafts 1 reaches the processing requirement, the sensor feeds back data to the first lifting drive component to suspend the use of the rotor shaft 1, thereby ensuring that the number of rotor shafts 1 taken out meets the processing requirement. No manual recording is required, which reduces the risk of inaccurate number of rotor shafts 1 affecting subsequent processing and improves the convenience and stability of equipment use.

[0068] Reference Figure 2 and Figure 3 In order to facilitate the storage of the rotor shaft 1, a storage opening 341 is opened at the upper end of the storage bin 34, and the storage bin 34 is equipped with an upper cover 342 for covering the storage opening 341. The upper cover 342 is openable and closable, and one end of the upper cover 342 is rotatably connected to the storage bin 34. When the rotor shaft 1 needs to be stored in the storage bin 34, it is only necessary to rotate the upper cover 342 so that the upper cover 342 no longer covers the storage opening 341, and then the rotor shaft 1 can be stored in the storage bin 34 through the storage opening 341. After the storage is completed, the upper cover 342 is rotated so that the upper cover 342 covers the storage opening 341 to prevent external substances from affecting the storage of the rotor shaft 1. At the same time, the storage operation of the rotor shaft 1 is simple and convenient, which improves the convenience of equipment use.

[0069] Reference Figure 2 and Figure 3 In order to reduce the risk that the rotor shaft 1 cannot be discharged from the storage bin 34 and affects the use of the rotor shaft 1, the outlet of the outlet end 343 is located at the bottom of the storage bin 34 to prevent the rotor shaft 1 from being located below the outlet of the outlet end 343 and causing the rotor shaft 1 to be unable to be discharged from the storage bin 34. In this way, the risk that the rotor shaft 1 cannot be discharged from the storage bin 34 and affects the use of the rotor shaft 1 is reduced, and the stability of the equipment use is improved.

[0070] Reference Figure 2 andFigure 3 , further, the bottom surface height of the storage bin 34 decreases from the side far away from the outlet end 343 to the side close to the outlet end 343, so that the rotor shaft 1 moves towards the direction close to the outlet end 343 under the action of its own gravity and applies a thrust to the rotor shaft 1 at the outlet end 343, thereby ensuring that the rotor shafts 1 are discharged out of the storage bin 34 one by one from the outlet of the outlet end 343, preventing the risk that the rotor shafts 1 cannot be discharged from the outlet of the outlet end 343 of the storage bin 34 due to the force applied between the rotor shafts 1 being too small to overcome the frictional force they bear, reducing the risk that the rotor shafts 1 cannot be discharged from the storage bin 34 and affecting the access to the rotor shafts 1, and improving the stability of equipment use.

[0071] Refer to Figure 2 and Figure 3 , considering that when multiple rotor shafts 1 are simultaneously discharged from the outlet of the outlet end 343 of the storage bin 34, it is easy for the rotor shafts 1 to be stacked together at the outlet end 343. The diameter of the rotor shaft 1 is D, and the distance between the two sides of the outlet of the outlet end 343 in the height direction is H, where D < H < 2D. That is, H being greater than D enables the rotor shaft 1 to be discharged from the storage bin 34 through the outlet of the outlet end 343, while H being less than 2D prevents two or more rotor shafts 1 from being discharged simultaneously from the outlet. In this way, the risk that the rotor shafts 1 are stacked together at the outlet end 343 when multiple rotor shafts 1 are simultaneously discharged from the outlet of the outlet end 343 of the storage bin 34 is reduced, preventing the situation where two or more rotor shafts 1 are stacked and moved to the lifting table 35, that is, preventing the lifting table 35 from transporting two or more rotor shafts 1 to the discharging position, ensuring that the first ejecting assembly 33 only applies a thrust to one rotor shaft 1 each time to eject it from the storage mechanism 3, improving the accuracy of accessing the rotor shafts 1, reducing the risk of unqualified motor rotors produced, and thus reducing the unqualified rate of motor rotors in production and processing.

[0072] Embodiment 2:

[0073] The difference from Embodiment 1 is that the discharging position is not located on the lifting table 35;

[0074] Refer to Figure 4 , a discharging table 312 corresponding to the discharging position is fixedly connected to the storage rack 31. The discharging table 312 and the outlet end 343 are respectively located on both sides of the support area 351. The side of the support area 351 facing the discharging table 312 is arranged in an open manner. When the lifting table 35 is in the second position, the bottom surface height of the support area 351 is higher than the bottom surface height of the discharging table 312, so that the rotor shaft 1 in the support area 351 can enter the discharging table 312. The rest of the structure is the same as that in the embodiment.

[0075] The implementation principle of an automatic feeding device for motor rotor shafts in Embodiment 2 of the present application is:

[0076] After the lifting table 35 moves to the second position, since the side of the support area 351 facing the discharging table 312 is arranged in an open manner, when the lifting table 35 is in the second position, the bottom surface height of the support area 351 is higher than the bottom surface height of the discharging table 312. The rotor shaft 1 on the support area 351 will accurately enter the discharging table 312 under the action of its own gravity, so that the rotor shaft 1 can accurately enter the discharging position, so that the first ejecting assembly 33 corresponding to the discharging position can accurately eject the rotor shaft 1 from the stock storage mechanism 3, preventing the first ejecting assembly 33 from being unable to eject the rotor shaft 1 due to the deviation of the rotor shaft 1 from the discharging position, reducing the risk of affecting the subsequent removal and processing of the rotor shaft 1 due to the inability to eject the rotor shaft 1, and improving the stability of the equipment use.

[0077] Embodiment 3:

[0078] Based on Embodiment 1 of the present application:

[0079] Referring to Figure 5 and Figure 6 , a buffer table 313 is installed at the outlet end 343. The buffer table 313 is located between the lifting table 35 and the outlet end 343 and is liftably installed on the stock storage rack 31. The buffer table 313 has a buffer area 3131. The first side 3132 of the buffer area 3131 facing the outlet end 343 and the second side 3133 facing the lifting table 35 are both arranged in an open manner. The bottom surface height of the buffer area 3131 decreases from the first side 3132 to the second side 3133. The buffer table 313 has a third position and a fourth position. When the buffer table 313 is in the third position, the bottom surface height of the first side 3132 is lower than the bottom surface height of the outlet end 343. When the buffer table 313 is in the fourth position and the lifting table 35 is in the first position, the bottom surface height of the second side 3133 is higher than the bottom surface height of the lifting table 35. The stock storage rack 31 is equipped with a second lifting drive member for driving the buffer table 313 to switch between the third position and the fourth position. The second lifting drive member uses a conventional drive cylinder. One end of the piston rod of the second lifting drive member is fixedly connected to the buffer table 313 and the other end is fixedly connected to the stock storage rack 31.

[0080] The implementation principle of the automatic feeding device for the motor rotor shaft 1 in Embodiment 3 of the present application is as follows:

[0081] When the rotor shaft 1 is discharged from the storage bin 34 through the outlet of the outlet end 343, when the buffer table 313 is in the third position, the bottom surface height of the first side 3132 is lower than the height of the outlet end 343. The bottom surface height of the buffer area 3131 decreases from the first side 3132 to the second side 3133. As a result, the rotor shafts 1 of multiple outlet ends 343 move from the outlet end 343 to the buffer area 3131, and after reaching the buffer area 3131, they move from the first side 3132 to the second side 3133 of the buffer area 3131 until the buffer area 3131 is fully covered. Then, the second lifting drive member drives the buffer table 313 to switch from the third position to the fourth position. When the buffer table 313 is in the fourth position, the bottom surface height of the second side 3133 is higher than the bottom surface height of the lifting table 35 when it is in the first position. Thus, the rotor shaft 1 closest to the lifting table 35 on the buffer area 3131 moves onto the lifting table 35 in the first position. Then, the first lifting drive member drives the lifting table 35 to switch from the first position to the second position to transport the rotor shaft 1 to the discharging position. Finally, the first ejecting assembly 33 ejects the rotor shaft 1 from the storage mechanism 3. After that, the first lifting drive member drives the empty lifting table 35 to switch from the second position to the first position. Another rotor shaft 1 on the buffer area 3131 moves onto the lifting table 35 again. Then, the lifting table 35 transports this rotor shaft 1 to the discharging position, and the first ejecting assembly 33 ejects the rotor shaft 1. This cycle continues until the last rotor shaft 1 on the buffer table 313 moves onto the empty lifting table 35. At this time, while the first lifting drive assembly drives the lifting table 35 to switch positions, the second lifting drive assembly drives the empty buffer table 313 to switch from the fourth position to the third position, allowing the rotor shafts 1 of the outlet end 343 to enter the buffer area 3131 again. After the buffer area 3131 is fully covered with rotor shafts 1, the second lifting drive member drives the buffer table 313 to switch from the third position to the fourth position. This cycle is repeated to eject the rotor shafts 1 from the storage mechanism 3 one by one. The use of the buffer table 313 enables multiple rotor shafts 1 to be transported from the third position to the fourth position and then enter the lifting table 35 one by one. This realizes the synchronous movement of multiple rotor shafts 1 during part of the time, and at the same time shortens the distance required for the lifting table 35 to move from the first position to the second position, that is, shortens the time required for the lifting table 35 to switch from the first position to the second position. Moreover, the switching of the position of the lifting table 35 and the switching of the position of the buffer table 313 can be carried out synchronously, thereby shortening the time required to take out a large number of rotor shafts 1 and improving the efficiency of the device for taking out the rotor shafts 1.

[0082] Refer to Figure 5 and Figure 6, in order to reduce the risk of the lifting table 35 and the buffer table 313 being unloaded, the buffer area 3131 is arranged closely adjacent to the lifting table 35. When the buffer table 313 is in the third position and the lifting table 35 is in the second position, the rotor shaft 1 in the buffer area 3131 is close to the side wall of the lifting table 35. The side wall hinders the movement of the rotor shaft 1 in the direction away from the outlet end 343, reducing the risk that the rotor shaft 1 continues to move in the direction away from the outlet end 343 after moving to the buffer area 3131 and falls off the buffer area 3131 and cannot enter the lifting table 35, that is, reducing the risk of the lifting table 35 being unloaded, preventing the lifting table 35 from being unloaded and affecting the material taking efficiency of the equipment for the rotor shaft 1, and improving the stability of equipment use.

[0083] Refer to Figure 5 and Figure 6 , in order to ensure that there are at least two rotor shafts 1 in the buffer area 3131 each time the buffer table 313 switches from the third position to the fourth position, the diameter of the rotor shaft 1 is D, and the width of the buffer area 3131 is L 2 , L 2 ≥2D, that is, the width L of the buffer area 3131 2 is greater than or equal to 2D, so that the buffer area 3131 can place at least two rotor shafts 1, to ensure that there are at least two rotor shafts 1 in the buffer area 3131 each time the buffer table 313 switches from the third position to the fourth position, reducing the risk that the buffer table 313 transports only one rotor shaft 1 each time and causes the material taking efficiency of the equipment for the rotor shaft 1 to decrease, and improving the stability of equipment use.

[0084] Embodiment 4:

[0085] Based on Embodiment 1:

[0086] Refer to Figure 1 and Figure 7 , the material taking mechanism 4 includes a moving frame 41 slidably connected to the fixed frame 2, a moving mechanism for driving the moving frame 41 to translate, a second ejecting assembly and four hollow tubes 43 installed on the moving frame 41. One end of the hollow tube 43 faces the discharging position, and the second ejecting assembly is installed at the other end of the hollow tube 43 and is used to eject the rotor shaft 1 in the hollow tube 43. The second ejecting assembly includes a first cylinder and a pushing rod. One end of the piston rod of the first cylinder is fixedly connected to the pushing rod, and the other end is fixedly connected to the moving frame 41. The moving mechanism includes a slide rail installed on the moving frame 41, a transmission lead screw rotatably connected to the fixed frame 2, a first motor installed on the fixed frame 2 and used to drive the transmission lead screw to rotate, and a sliding block installed on the moving frame 41. The sliding block is slidably matched with the slide rail to limit the rotation of the sliding block and the sliding block is threadedly connected to the transmission lead screw.

[0087] The implementation principle of the automatic feeding equipment for the motor rotor shaft in Embodiment 4 of the present application is:

[0088] When the lifting platform 35 switches from the first position to the second position, so that the corresponding rotor shaft 1 is in the discharge position, the moving mechanism drives the moving frame 41 to translate, that is, the first motor drives the transmission screw to rotate, so that the sliding block slides in the extension direction of the transmission screw, that is, the translation of the moving frame 41 is realized, so that one end of the hollow tube 43 is facing the discharge position. At this time, the first ejection component 33 applies a thrust to the rotor shaft 1 to make it move in the direction close to the hollow tube 43, so that the rotor shaft 1 moves as a whole from the discharge position to the inner cavity of the hollow tube 43. There are four hollow tubes 43, and the moving mechanism drives the moving frame 41 to translate so that another hollow tube 43 is opposite to the discharging position, and the rotor shafts 1 are taken out one by one in this cycle. After a rotor shaft 1 exists in each of the four hollow tubes 43, the moving mechanism drives the moving frame 41 to translate to the next workbench for processing the rotor shaft 1, and then the second ejection assembly ejects the rotor shaft 1 in the hollow tube 43, thereby ensuring that the four rotor shafts 1 are taken out one by one while realizing the simultaneous transportation of the four rotor shafts 1, thereby improving the transportation efficiency of the taking mechanism 4 for the rotor shaft 1.

[0089] In order to ensure that the rotor shaft 1 is smoothly pushed onto the material-retrieving mechanism 4, the material-retrieving mechanism 4 also includes a vacuum negative pressure component installed on the movable frame 41, and the vacuum negative pressure component is connected to the inner cavity of the hollow tube 43 to generate negative pressure in the inner cavity, so that when the first ejection component 33 applies a thrust to the rotor shaft 1 to make it move toward the direction close to the hollow tube 43, the vacuum negative pressure component causes the inner cavity of the hollow tube 43 to generate negative pressure, so that the inner cavity of the hollow tube 43 generates suction on the rotor shaft 1 due to the pressure difference, so that the rotor shaft 1 moves as a whole from the discharge position to the inner cavity of the hollow tube 43, thereby increasing the probability that the rotor shaft 1 enters the hollow tube 43 completely, and preventing the risk that the first ejection component 33 has a small thrust on the rotor shaft 1, resulting in a partial area of ​​the rotor shaft 1 not entering the hollow tube 43, thereby reducing the risk that the hollow tube 43 is empty and affects the transportation efficiency of the rotor shaft 1 and the risk that the rotor shaft 1 fails to be smoothly removed and affects subsequent processing, thereby improving the stability of equipment use.

[0090] Embodiment 5:

[0091] Based on Example 1:

[0092] Reference Figure 1 , Figure 8 and Figure 9 A groove 11 is provided at one end of the rotor shaft 1, a detection mechanism 5 for detecting whether the rotor shaft 1 is in the forward direction is installed between the material storage mechanism 3 and the material taking mechanism 4, and a rotor shaft 1 recovery box is installed below the detection mechanism 5.

[0093] Reference Figure 1 , Figure 8 and Figure 9, the first ejection component 33 pushes the rotor shaft 1 at the discharging position onto the detection mechanism 5. The material taking mechanism 4 has an initial position and a receiving position corresponding to the detection mechanism 5. If the detection result of the detection mechanism 5 is positive, the material taking mechanism 4 moves to the receiving position, and the first ejection component 33 pushes the rotor shaft 1 on the detection mechanism 5 onto the material taking mechanism 4. If the detection result of the detection mechanism 5 is negative, the material taking mechanism 4 is at the initial position, and the first ejection component 33 pushes the rotor shaft 1 on the detection mechanism 5 into the rotor shaft 1 recycling box. The initial position is the position where the material taking mechanism 4 cannot receive the rotor shaft 1 on the detection mechanism 5.

[0094] Refer to Figure 1 , Figure 8 and Figure 9 , the material storage mechanism 3 is located on the left side of the rotor shaft 1. The first ejection component 33 pushes the rotor shaft 1 from left to right onto the detection mechanism 5. The positive rotor shaft 1 has the groove 11 on the side of the rotor shaft 1 close to the material storage mechanism 3, and the negative rotor shaft 1 has the groove 11 on the side of the rotor shaft 1 far from the material storage mechanism 3.

[0095] The implementation principle of the automatic feeding device for the motor rotor shaft in Embodiment 5 of the present application is as follows:

[0096] The rotor shaft 1 is stored in the material storage mechanism 3. The positive direction of the rotor shaft 1 means that the groove 11 of the rotor shaft 1 is located at one end of the rotor shaft 1 close to the material storage mechanism 3, and the negative direction of the rotor shaft 1 means that the groove 11 of the rotor shaft 1 is located at one end of the rotor shaft 1 far from the material storage mechanism 3. The first ejection component 33 pushes the entire rotor shaft 1 at the discharging position onto the detection mechanism 5 and pushes it to the corresponding position on the detection mechanism 5. The detection mechanism 5 detects the rotor shaft 1 and feeds back the information to the material taking mechanism 4. If the rotor shaft 1 is positive, the material taking mechanism 4 moves to the receiving position, and the first ejection component 33 pushes the rotor shaft 1 on the detection mechanism 5 onto the material taking mechanism 4, so that the positive rotor shaft 1 can enter the material taking mechanism 4. If the rotor shaft 1 is negative, the material taking mechanism 4 remains at the initial position, and the first ejection component 33 pushes the rotor shaft 1 on the detection mechanism 5 into the rotor shaft 1 recycling box, so that the negative rotor shaft 1 cannot enter the material taking mechanism 4. That is, through the detection mechanism 5, the rotor shaft 1 with the wrong direction is excluded before being pushed into the material taking mechanism 4 and cannot enter the material taking mechanism 4. That is, the directions of the rotor shafts 1 taken out by the material taking mechanism 4 are all the same and positive, reducing the risk of unqualified motor rotors produced due to the wrong direction of the rotor shaft 1 and reducing the unqualified rate of the motor rotors in production and processing.

[0097] Refer to Figure 10, the first ejecting component 33 further includes a second telescopic driving member 332. The second telescopic driving member 332 is installed at the telescopic end of the first telescopic driving member 331, and the ejecting shaft is installed at the telescopic end of the second telescopic driving member 332. The material taking mechanism 4 is located on one side of the discharging position. Both the first telescopic driving member 331 and the second telescopic driving member 332 adopt conventional driving cylinders. One end of the piston rod of the second telescopic driving member 332 is fixedly connected to the ejecting shaft, and the other end is fixedly connected to one end of the piston rod of the first telescopic driving member 331. The other end of the first telescopic driving member 331 is fixedly connected to the storage rack 31. When the first ejecting component 33 pushes the rotor shaft 1 at the discharging position to the detection mechanism 5, the second telescopic driving member 332 extends, causing the ejecting shaft to move in the reverse direction close to the rotor shaft 1 at the discharging position and applying a thrust to the rotor shaft 1 to push it onto the detection mechanism 5; when the first ejecting component 33 needs to push the rotor shaft 1 on the detection mechanism 5 to the material taking mechanism 4 or the rotor shaft 1 recycling box, the first telescopic driving member 331 extends, causing the ejecting shaft to apply a thrust to the rotor shaft 1 on the detection mechanism 5 again, so that it is pushed to the material taking mechanism 4 or the rotor shaft 1 recycling box. In order to ensure that the rotor shaft 1 can be pushed to the specified position on the detection mechanism 5, the extension rate of the second telescopic driving member 332 is relatively slow, that is, the ejecting shaft will slowly push the rotor shaft 1 to enter the detection mechanism 5, and there is a frictional force between the rotor shaft 1 and the detection mechanism 5 when the rotor shaft 1 is pushed onto the detection mechanism 5. By making the rotor shaft 1 slowly slide onto the detection mechanism 5, the inertial force of the rotor shaft 1 is less than the frictional force it receives, thereby reducing the risk of the rotor shaft 1 deviating from the specified position due to inertia and improving the accuracy of equipment use.

[0098] Embodiment 6:

[0099] Based on Embodiment 5 of the present application:

[0100] Refer to Figure 11 and Figure 12 , the detection mechanism 5 includes a mounting bracket 51 fixedly connected to the fixed bracket 2, a clamping mechanism 52 installed on the mounting bracket 51 and used for clamping the rotor shaft 1 and engaging with the groove 11 on the rotor shaft 1, and a detection sensor 53 for detecting whether there is a rotor shaft 1 on the mounting bracket 51.

[0101] Refer to Figure 11 and Figure 12, the clamping mechanism 52 includes a clamping drive assembly 7 mounted on the mounting bracket 51 and a clamping assembly 8 slidably connected to the mounting bracket 51. The mounting bracket 51 is provided with a through hole 511. The number of the clamping assemblies 8 is four, and the four clamping assemblies 8 are arranged at intervals along the circumference of the through hole 511. The clamping mechanism 52 has an unlocked state and a locked state. When the clamping mechanism 52 is in the locked state, the four clamping assemblies 8 clamp the rotor shaft 1 and one of the clamping assemblies 8 is engaged in the groove 11 to limit the sliding of the rotor shaft 1 relative to the mounting bracket 51. When the clamping mechanism 52 is in the unlocked state, the four clamping assemblies 8 all release the rotor shaft 1 so that the rotor shaft 1 can slide relative to the mounting bracket 51. The clamping drive assembly 7 can drive the clamping assembly 8 to slide in a direction away from or close to the through hole 511 to realize the switching between the unlocked state and the locked state of the clamping mechanism 52. Refer to Figure 11 and Figure 12 , the mounting bracket 51 is provided with a sliding groove 512 communicating with the through hole 511. The clamping assembly 8 includes a sliding frame 81, a sliding block 82 and an elastic member 83 slidably connected in the sliding groove 512. The sliding block 82 is slidably connected to the sliding frame 81. The elastic member 83 is located between the sliding frame 81 and the sliding block 82 and is used to make the sliding block 82 protrude towards the through hole 511. The elastic member 83 adopts a conventional compression spring. One end of the elastic member 83 is fixedly connected to the sliding frame 81 and the other end is fixedly connected to the sliding block 82.

[0102] Refer to Figure 11 and Figure 12 , when the clamping mechanism 52 is in the locked state, the four sliding blocks 82 all abut against the rotor shaft 1 and one of the sliding blocks 82 is engaged in the groove 11 to limit the sliding of the rotor shaft 1 relative to the mounting bracket 51. When the clamping assembly 8 is in the unlocked state, there is a certain distance between the four sliding blocks 82 and the hole wall of the through hole 511 so that the rotor shaft 1 can slide relative to the mounting bracket 51.

[0103] Refer to Figure 11 and Figure 12 , the detection sensor 53 includes a laser receiving end 531 and a laser emitting end 532. The laser receiving end 531 and the laser emitting end 532 are both mounted on the mounting bracket 51 and are respectively located on opposite sides of the through hole 511. Even when the rotor shaft 1 is located on the mounting bracket 51, that is, when the rotor shaft 1 passes through the through hole 511, the rotor shaft 1 will block the laser emitted by the laser emitting end 532, thereby hindering the propagation of the laser and making the laser receiving end 531 unable to receive the laser. When the rotor shaft 1 is not located on the mounting bracket 51, the laser emitted by the laser emitting end 532 will not be blocked, so that the laser receiving end 531 can receive the laser, enabling the detection sensor 53 to judge whether there is a rotor shaft 1 on the mounting bracket 51 at this moment.

[0104] The implementation principle of the automatic feeding device for the motor rotor shaft in Embodiment 6 of the present application is as follows:

[0105] When the second telescopic driving member 332 extends to push the entire rotor shaft 1 at the discharging position onto the detection mechanism 5, about to push the entire rotor shaft 1 onto the mounting bracket 51, and when the rotor shaft 1 is pushed onto the mounting bracket 51 and reaches the designated position corresponding to the clamping mechanism 52, then after reaching the designated position, the clamping mechanism 52 clamps the rotor shaft 1, that is, the clamping drive assembly 7 drives the clamping assembly 8 to slide in the direction close to the through hole 511 to switch the clamping mechanism 52 from the unlocked state to the locked state. If the rotor shaft 1 is in the forward direction, all four sliding blocks 82 are in contact with the rotor shaft 1 and one of the sliding blocks 82 is inserted into the groove 11 to limit the sliding of the rotor shaft 1 relative to the mounting bracket 51; if the rotor shaft 1 is in the reverse direction, since the position of the groove 11 on the reverse rotor shaft 1 is inconsistent with that of the groove 11 on the forward rotor shaft 1, the groove 11 on the reverse rotor shaft 1 will deviate from the designated position of the clamping mechanism 52, that is, each sliding block 82 will be in contact with the circumferential side wall of the reverse rotor shaft 1 to clamp the rotor shaft 1, but none of them will be inserted into the groove 11 of the rotor shaft 1; after the clamping mechanism 52 clamps the rotor shaft 1, the first ejecting assembly 33 will apply a thrust to the rotor shaft 1 on the mounting bracket 51 again, that is, the first telescopic driving member 331 extends. Since one of the sliding blocks 82 is inserted into the groove 11 of the forward rotor shaft 1, the sliding block 82 will apply a thrust to the groove wall of the groove 11 to prevent the sliding of the rotor shaft 1. And because the circumferential side wall of the rotor shaft 1 is relatively smooth, the frictional force between the rotor shaft 1 and the sliding block 82 is small, and the reverse rotor shaft 1 will be pushed off the mounting bracket 51. At this time, the material taking mechanism 4 is at the initial position, that is, the reverse rotor shaft 1 will fall into the rotor shaft 1 recovery box; after a period of time after the first telescopic driving member 331 acts, ensure that the reverse rotor shaft 1 has fallen into the rotor shaft 1 recovery box, read the data of the detection sensor 53 at this moment and feedback the information to the material taking mechanism 4. If the rotor shaft 1 is in the reverse direction, the detection transmission device will detect that there is no rotor shaft 1 on the mounting bracket 51 at this moment, and the material taking mechanism 4 will remain at the initial position; if the rotor shaft 1 is in the forward direction, the detection transmission device detects that there is a rotor shaft 1 on the mounting bracket 51 at this moment, and the material taking mechanism 4 will move from the initial position to the receiving position; then the clamping drive assembly 7 drives the clamping assembly 8 to move in the direction away from the through hole 511 to switch the clamping mechanism 52 from the locked state to the unlocked state, canceling the clamping of the rotor shaft 1. For the forward rotor shaft 1, the sliding block 82 is no longer inserted into the groove 11, that is, the sliding block 82 no longer applies a thrust to the groove wall of the groove 11, so that the first telescopic driving member 331 can extend, thereby applying a thrust to the rotor shaft 1 again. Since the material taking mechanism 4 has moved to the receiving position, the rotor shaft 1 is pushed onto the material taking mechanism 4, that is, the forward rotor shaft 1 is pushed onto the material taking mechanism 4; among them, through the cooperation of the clamping mechanism 52 and the groove 11 of the rotor shaft 1, the rotor shaft 1 with the wrong direction will be automatically pushed into the rotor shaft 1 recovery box without manual operation, improving the convenience of equipment use.Meanwhile, the number of the clamping assemblies 8 is four and they are arranged at intervals along the circumferential direction of the through hole 511, thus preventing the clamping assembly 8 from failing to be engaged into the groove 11 due to the deviation of the groove 11 of the rotor shaft 1 from the clamping assembly 8, reducing the situation that the rotor shaft 1 with the correct direction cannot be pushed onto the material taking mechanism 4 because the clamping assembly 8 fails to be engaged into the groove 11, and improving the accuracy of the detection mechanism 5. Moreover, the elastic member 83 plays a certain guiding role during the sliding process of the sliding block 82, preventing the sliding path of the sliding block from deviating and affecting the clamping of the rotor shaft 1, and improving the stability of the equipment.

[0106] To prevent the sliding block 82 from being in contact and cooperation with the rotor shaft 1, which is likely to cause damage to the rotor shaft 1, the sliding block 82 is made of a soft metal material such as copper to reduce the risk of damage to the rotor shaft 1 caused by the contact of the sliding block 82.

[0107] Refer to Figure 13 、 Figure 14 and Figure 15, Further, the clamping drive assembly 7 includes a rotating frame 71 rotatably connected to the mounting frame 51 and a rotation drive member 72 mounted on the mounting frame 51 and used to drive the rotation of the rotating frame 71. The rotating frame 71 is provided with a plurality of arc-shaped grooves 711 corresponding one-to-one to the sliding blocks 82. The sliding frame 81 is fixedly connected with a guiding member 811 for extending into the corresponding arc-shaped groove 711. The guiding member 811 is a guiding rod 8111 penetrating through the sliding frame 81. The groove wall of the sliding groove 512 is provided with guiding grooves 5121 corresponding one-to-one to the sliding blocks. One end of the guiding rod 8111 is slidably connected in the arc-shaped groove 711, and the other end is slidably connected in the guiding groove 5121. The rotation drive member 72 adopts a conventional drive cylinder. One end of the rotation drive member 72 is hinged to the mounting frame 51, and the other end is hinged to the rotating frame 71. The extending direction of the guiding groove 5121 is the extending direction of the aperture of the through hole 511. The arc-shaped groove 711 is eccentrically arranged relative to the rotation axis of the rotating frame 71, so that when the rotating frame 71 rotates relative to the mounting frame 51, the guiding rod 8111 moves in a direction away from or close to the through hole 511 under the guiding action of the arc-shaped groove 711. Since the arc-shaped groove 711 is eccentrically arranged relative to the rotation axis of the rotating frame 71, the distances between the two ends of the arc-shaped groove 711 and the axis of the rotation axis are different. When it is necessary to make the sliding block 82 rotate in a direction close to or away from the through hole 511, the rotation drive member 72 expands and contracts to drive the rotating frame 71 to rotate relative to the mounting frame 51. The arc-shaped groove 711 exerts a thrust on the guiding rod 8111 to make the guiding rod 8111 slide. Since the other end of the guiding rod 8111 is slidably connected in the guiding groove 5121, and the extending direction of the guiding groove 5121 is the extending direction of the aperture of the through hole 511, that is, the groove wall of the guiding groove 5121 will limit the sliding direction of the guiding rod 8111, so that a plurality of guiding rods 8111 move in a direction away from or close to the through hole 511 at the same time, that is, it realizes that a plurality of sliding blocks move in a direction away from or close to the through hole 511 at the same time. That is, by driving the rotation of the rotating frame 71 by the rotation drive member 72, the movement of a plurality of clamping assemblies 8 is realized, and it is not necessary to drive each clamping assembly 8 one by one, the operation is convenient and fast, and the convenience of equipment use is improved. At the same time, only one power source, the rotation drive member 72, is adopted, which reduces the use cost of the equipment.

[0108] Refer to Figure 11 and Figure 12 , Preferably, every two oppositely arranged clamping assemblies 8 form a first assembly 84 and a second assembly 85 as a group. When the clamping assembly 8 is in the unlocked state, the distance between the end of the sliding block 82 in the first assembly 84 close to the through hole 511 and the hole wall of the through hole 511 is S 1 , the distance between the end of the sliding block 82 in the second assembly 85 close to the through hole 511 and the hole wall of the through hole 511 is S 2 , S 1 <S 2When the slider 82 in the second component 85 abuts against the circumferential side wall of the rotor shaft 1, the elastic force of the elastic member 83 in the second component 85 is F 1 The elastic force of the elastic member 83 in the first component 84 is F 2 F 1 >F 2 If the angle of the groove 11 of the forward rotor shaft 1 deviates from the clamping assembly 8, when the clamping mechanism 52 clamps the rotor shaft 1, that is, the clamping mechanism 52 is switched from the unlocked state to the locked state. During this process, due to S 1 is less than S 2 Therefore, the slider 82 in the first component 84 will first abut and cooperate with the circumferential side wall of the rotor shaft 1, and one of the sliders 82 is partially located at the notch of the groove 11 of the rotor shaft 1. Then, when the slider 82 in the second component 85 abuts against the circumferential side wall of the rotor shaft 1, one of the sliders 82 is also partially located at the notch of the groove 11. Due to F 1 is greater than F 2 and the surface of the rotor shaft 1 is smooth, the slider 82 in the second component 85 will push the rotor shaft 1 to rotate until the corresponding slider 82 in the second component 85 is stuck into the groove 11, so as to realize the clamping of the forward rotor shaft 1 and limit the relative sliding of the forward rotor shaft 1 with respect to the mounting bracket 51, reducing the situation that the clamping assembly 8 cannot be stuck into the groove 11 and resulting in the correct-direction rotor shaft 1 not being pushed onto the material taking mechanism 4, and improving the accuracy of the detection mechanism 5

[0109] Further, during the process of the clamping mechanism 52 being switched from the unlocked state to the locked state, F 1 is always greater than F 2 Thereby ensuring that the slider 82 in the second component 85 can push the rotor shaft 1 clamped by the slider 82 in the first component 84, reducing the situation that the clamping assembly 8 cannot be stuck into the groove 11 and resulting in the correct-direction rotor shaft 1 not being pushed onto the material taking mechanism 4, and further improving the accuracy of the detection mechanism 5
