Description

[0001] The application is a divisional application, the original application date is June 11, 2024, the original application application number is 2024107442730, and the original application name is a motor rotor shaft automatic feeding equipment. TECHNICAL FIELD

[0002] The application relates to the technical field of motor production equipment, in particular to a motor rotor shaft forward and reverse detection mechanism. BACKGROUND

[0003] A motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the electromagnetic induction law, or converts one form of electric energy into another form of electric energy, which is composed 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. The existing motor rotor structure is mostly composed of an armature, a coil, a rotor shaft and other accessories, and the rotor shaft is a transmission structure. The rotor shaft is a core structure that connects the rotor components, usually made of metal materials such as steel or aluminum alloy, mainly used to support and connect other components on the rotor, and allows the rotor to rotate in the axial direction, playing a role in supporting and transmitting power.

[0004] In the batch production process of the motor rotor, a large number of processed rotor shafts will be stored in the storage bin. When the motor rotor is processed and produced, the rotor shaft needs to be taken out from the storage bin and transported to the next workbench for waiting for die casting processing. Since the rotor on the rotor shaft is formed by die casting, a groove is generally provided on the rotor shaft to increase the connection strength of the rotor and the rotor shaft after die casting. The groove is provided on the circumferential side wall of one end of the rotor shaft, i.e. the groove deviates from the middle position in the length direction of the rotor shaft. Therefore, in order to facilitate subsequent processing of the rotor shaft, the direction of the rotor shaft taken out from the storage bin should be the same as the direction of the end of the rotor shaft where the groove is provided. However, when the rotor shaft is placed in the storage bin, the rotor shaft may be turned over, and the operator may also place it in the wrong direction one by one, which changes the direction of the rotor shaft in the storage bin, so that the direction of the rotor shaft taken out from the storage bin may not be consistent with the specified direction, thereby increasing the unqualified rate of the motor rotor produced due to the wrong direction of the rotor shaft. SUMMARY

[0005] The motor rotor shaft forward and reverse detection mechanism can detect the forward and reverse directions of the motor rotor shaft conveyed from the storage bin, thereby reducing the risk of the produced motor rotor being unqualified due to the incorrect direction of the motor rotor shaft, and reducing the unqualified rate of the motor rotor in the production and processing.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0007] A motor rotor shaft forward and reverse detection mechanism, one end of the rotor shaft is provided with a groove, the detection mechanism comprises a mounting frame, a clamping mechanism mounted on the mounting frame and used for clamping the rotor shaft and clamping into the groove, and a detection sensor used for detecting whether the rotor shaft exists on the mounting frame; one side of the mounting frame is provided with a first ejection assembly used for applying a pushing force to the rotor shaft on the mounting frame; the clamping mechanism comprises a clamping driving assembly mounted on the mounting frame and a clamping assembly slidingly connected to the mounting frame, the mounting frame is provided with a through hole, the clamping assembly is provided with four, the four clamping assemblies are circumferentially spaced apart along the through hole, the clamping mechanism has an unlocked state and a locked state, when the clamping mechanism is in the locked state, the four clamping assemblies clamp the rotor shaft and one of the clamping assemblies clamps into the groove to limit the slip of the rotor shaft relative to the mounting frame, when the clamping mechanism is in the unlocked state, the four clamping assemblies are all loosened from the rotor shaft so that the rotor shaft can slip relative to the mounting frame, the clamping driving assembly can drive the clamping assembly to slide away from or close to the through hole to realize the switching between the unlocked state and the locked state of the clamping mechanism, when the clamping mechanism is in the locked state, the frictional force between the rotor shaft and the clamping assembly is smaller than the pushing force of the first ejection assembly to the rotor shaft.

[0008] In the above technical solution, the first ejection assembly pushes the rotor shaft to the mounting rack of the detection mechanism, and then the clamping mechanism clamps the rotor shaft. If the rotor shaft is forward, the clamping mechanism clamps the rotor shaft and is clamped into the groove of the rotor shaft. If the rotor shaft is reverse, the groove on the reverse rotor shaft deviates from the specified position corresponding to the clamping mechanism because the positions of the groove of the reverse rotor shaft and the groove of the forward rotor shaft are inconsistent. That is, the clamping mechanism abuts against the circumferential side wall of the reverse rotor shaft to clamp the rotor shaft, but will not be clamped into the groove of the rotor shaft. After the clamping mechanism clamps the rotor shaft, the first ejection assembly applies a pushing force to the rotor shaft on the mounting rack again. Because the clamping mechanism is clamped into the groove of the forward rotor shaft, the clamping mechanism applies a pushing force to the groove wall to prevent the rotor shaft from slipping. Because the circumferential side wall of the rotor shaft is relatively smooth, the friction between the rotor shaft and the clamping mechanism is small, and the reverse rotor shaft will be pushed off the mounting rack. After the first ejection assembly works for a period of time, the data of the detection sensor at this moment is read. If the detection mechanism detects that there is a rotor shaft on the mounting rack at this moment, the motor rotor shaft is forward. If the detection mechanism detects that there is no rotor shaft on the mounting rack at this moment, the motor rotor shaft is reverse.

[0009] Preferably, the clamping assembly includes a sliding frame, a sliding block and an elastic member arranged on the mounting rack. The sliding block is slidingly connected to the sliding frame. The elastic member is located between the sliding frame and the sliding block and is used to make the sliding block extend to the direction of the through hole. When the clamping mechanism is in the locked state, the sliding blocks abut against the rotor shaft, and one of the sliding blocks is clamped into the groove to limit the slip of the rotor shaft relative to the mounting rack. When the clamping assembly is in the unlocked state, there is a distance between the sliding blocks and the hole wall of the through hole, so that the rotor shaft can slip relative to the mounting rack.

[0010] Preferably, the clamping assembly is provided with four clamping assemblies. Every two oppositely arranged clamping assemblies form a first assembly and a second assembly. When the clamping assembly is in the unlocked state, the distance between the sliding block in the first assembly close to one end of the through hole and the hole wall of the through hole is S1, and the distance between the sliding block in the second assembly close to one end of the through hole and the hole wall of the through hole is S2. S1 < S2. When the sliding block in the second assembly abuts against the rotor shaft, the elastic force of the elastic member in the second assembly is F1, and the elastic force of the elastic member in the first assembly is F2. F1 > F2.

[0011] Preferably, F1 is always greater than F2 during the process of switching the clamping mechanism from the unlocked state to the locked state.

[0038] Embodiment 1

[0039] The embodiment 1 of the application discloses a motor rotor shaft automatic feeding device.

[0040] With reference to Figure 1 , Figure 2 and Figure 3 , a motor rotor shaft automatic feeding device comprises a fixing frame 2, a storage mechanism 3 and a taking mechanism 4 installed on the fixing frame 2, the storage mechanism 3 comprises a storage rack 31 fixedly connected with the fixing frame 2, a storage bin 34, a discharging part 32, a first ejection assembly 33, a lifting table 35 and a first lifting driving member installed on the storage rack 31.

[0041] With reference to Figure 1 , Figure 2 and Figure 3 , the discharging part 32 is a discharging hole 321 opened in the storage rack 31 and corresponding to the taking mechanism 4, the storage rack 31 has a discharging position corresponding to the discharging hole 321, the discharging position is a position in the storage rack 31 where the first ejection assembly 33 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 member drives the lifting table 35 to switch between the first position and the second position to make the rotor shaft 1 on the lifting table 35 enter the discharging position, the first lifting driving member adopts a conventional driving cylinder, one end of the piston rod of the first lifting driving member is fixedly connected with the lifting table 35, and the other end is fixedly connected with the storage rack 31.

[0042] With reference to Figure 1 , Figure 2 and Figure 3 , the taking mechanism 4 is located on one side of the discharging position, the first ejection assembly 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 taking mechanism 4, the first ejection assembly 33 comprises a first telescopic driving member 331 and an ejection shaft, the ejection shaft is installed on the telescopic end of the first telescopic driving member 331, the first telescopic driving member 331 adopts a conventional driving cylinder, one end of the piston rod of the first telescopic driving member 331 is connected with the ejection shaft, and the other end is fixedly connected with the storage rack 31.

[0043] The implementation principle of the motor rotor shaft automatic feeding device in the embodiment 1 of the application is as follows:

[0044] When the device is used for taking out the rotor shafts, a large number of rotor shafts 1 are stacked in the storage bin 34, and the rotor shafts 1 under the action of gravity will apply a pushing force to the rotor shafts 1 at the outlet end 343, so that the rotor shafts 1 move out of the storage bin 34 through the outlet of the outlet end 343. At the first time, the lifting platform 35 is located at a first position corresponding to the outlet end 343, and one of the rotor shafts 1 moved out of the outlet will move to the lifting platform 35, and the other rotor shafts 1 are located outside the lifting platform 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, so the first position is higher than the second position. Then the first lifting driving element drives the lifting platform 35 to rise and switch from the first position to the second position corresponding to the discharging position, so that the rotor shaft 1 on the lifting platform 35 enters the discharging position. Then the first ejection assembly 33 pushes the rotor shaft 1 in the discharging position out of the discharging hole 321 to the taking-out mechanism 4, i.e., the first telescopic driving element 331 is extended to make the ejecting shaft slide towards the rotor shaft 1 in the discharging position, so that the ejecting shaft applies a pushing force to the rotor shaft 1 to slide towards the taking-out mechanism 4, thereby pushing the rotor shaft 1 to the taking-out mechanism 4. The taking-out mechanism 4 transports the rotor shaft 1 to the next processing position, i.e., one rotor shaft 1 is taken out from the storage mechanism 3. Then the first lifting driving element drives the lifting platform 35 to descend and switch from the second position to the first position. Since the lifting platform 35 is in an empty state at this time, the rotor shaft 1 at the other outlet end 343 moves to the empty lifting platform 35 under the action of the pushing force between the rotor shafts 1. The first lifting driving element drives the lifting platform 35 to rise again and switch from the first position to the second position, so that the rotor shaft 1 on the lifting platform 35 enters the discharging position. The first ejection assembly 33 pushes the rotor shaft 1 in the discharging position to the taking-out mechanism 4 again. In this way, the rotor shaft 1 is taken out one by one. The rotor shaft 1 is transported to the discharging position one by one through the switching of the position of the lifting platform 35, and then the rotor shaft 1 is pushed out of the storage mechanism 3 one by one through the first ejection assembly 33, which ensures that the first ejection assembly 33 applies a pushing force to only one rotor shaft 1 each time to eject it out of the storage mechanism 3, improves the accuracy of taking out the rotor shaft 1, reduces the risk of unqualified motor rotor in production, and thus reduces the unqualified rate of motor rotor in production and processing.

[0045] Referring to Figure 2 and Figure 3, in order to reduce the risk of the lifting platform 35 being empty, the lifting platform 35 has a support area 351, the support area 351 is arranged open towards one side of 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 away from the outlet end 343. Wherein the support area 351 is arranged open towards one side of the outlet end 343, so that when the lifting platform 35 is in the first position, the rotor shaft 1 enters the support area 351 through the side of the support area 351 close to 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 away 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 away from the outlet end 343 under the action of its own gravity, reducing the risk of the rotor shaft 1 falling from the lifting platform 35 back to the outlet end 343 due to the rotor shaft 1 being at the edge of the support area 351, thereby reducing the risk of the lifting platform 35 being empty, preventing the lifting platform 35 from being empty and affecting the efficiency of the equipment in taking the rotor shaft 1, and improving the stability of the equipment in use.

[0046] With reference to Figure 2 and Figure 3 Further, the storage rack 31 has a positioning side wall 311, and the side of the lifting platform 35 away from the outlet end 343 is arranged close to the positioning side wall 311, so that the rotor shaft 1 on the support area 351 is close to the positioning side wall 311. Wherein the positioning side wall 311 hinders the movement of the rotor shaft 1 away from the outlet end 343, reducing the risk of the rotor shaft 1 moving away from the outlet end 343 after moving to the support area 351 and falling from the lifting platform 35, i.e. reducing the risk of the lifting platform 35 being empty, preventing the lifting platform 35 from being empty and affecting the efficiency of the equipment in taking the rotor shaft 1, and improving the stability of the equipment in use.

[0047] With reference to Figure 2 and Figure 3In order to further reduce the risk of the lifting platform 35 being empty, the diameter of the rotor shaft 1 is D, the width of the support area 351 is L1, 0.5D

[0048] Preferably, 1.1D

[0049] With reference to Figure 2 and Figure 3In order to reduce the energy consumption of the equipment, the storage rack 31 is provided with a first sensor 314 for detecting whether the rotor shaft 1 exists at the discharging position. The first sensor 314 adopts a conventional laser sensor, and includes a first emitting end and a first receiving end, which are respectively located on both sides of the discharging position. When the rotor shaft 1 does not exist at the discharging position, the first receiving end will receive the laser emitted by the first emitting end. When the rotor shaft 1 exists at the discharging position, the rotor shaft 1 will block the laser emitted by the first emitting end, so that the first sensor 314 cannot receive the laser, and thus can determine whether the rotor shaft 1 exists at the discharging position, and record the number of rotor shafts 1 taken out by the number of times of being blocked. The detection of the first sensor 314 on whether the rotor shaft 1 exists at the discharging position can feed back to the first ejection assembly 33, reduce the risk of useless work of the first ejection assembly 33, 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 the rotor shaft 1 exists at the discharging position. When the number of rotor shafts 1 reaches the processing requirement, the sensor will feed back the data to the first lifting driving member to pause the taking of the rotor shaft 1, so as to ensure that the number of rotor shafts 1 taken out meets the processing requirement, without the need for manual recording, thereby reducing the risk of affecting the subsequent processing due to inaccurate number of rotor shafts 1, and improving the convenience and stability of the equipment.

[0050] With reference to Figure 2 and Figure 3 , in order to facilitate the storage of the rotor shaft 1, the upper end of the storage bin 34 is provided with a storage opening 341, and the storage bin 34 is provided with an upper cover 342 for shielding the storage opening 341. The upper cover 342 is arranged to be openable and closable, and one end of the upper cover 342 is rotationally connected to the storage bin 34. When it is necessary to store the rotor shaft 1 in the storage bin 34, the upper cover 342 is rotated to no longer shield the storage opening 341, and then the rotor shaft 1 is stored in the storage bin 34 through the storage opening 341. After storage is completed, the upper cover 342 is rotated to shield the storage opening 341, preventing external substances from affecting the storage of the rotor shaft 1, and making the storage operation of the rotor shaft 1 simple and convenient, thereby improving the convenience of the equipment.

[0051] With reference to 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 affect the taking of the rotor shaft 1, the outlet of the outlet end 343 is located at the bottom of the storage bin 34, preventing 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, thereby reducing the risk that the rotor shaft 1 cannot be discharged from the storage bin 34 and affect the taking of the rotor shaft 1, and improving the stability of the equipment.

[0052] With reference to 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 shafts 1 move towards the outlet end 343 under the action of their own gravity and apply a pushing force to the rotor shaft 1 of the outlet end 343, thereby ensuring that the rotor shafts 1 are discharged one by one from the outlet of the outlet end 343 to the outside of the storage bin 34, preventing the risk that the rotor shafts 1 cannot be discharged from the outlet end 343 due to the insufficient force applied by the rotor shafts 1 to each other to overcome the friction, reducing the risk that the rotor shafts 1 cannot be discharged from the storage bin 34 and affecting the use of the rotor shafts 1, and improving the stability of the use of the equipment.

[0053] With reference to Figure 4 and Figure 5 , considering that the simultaneous discharge of multiple rotor shafts 1 from the outlet of the outlet end 343 to the storage bin 34 is prone to cause the rotor shafts 1 to be stacked together at the outlet end 343, the diameter of the rotor shaft 1 is D, the distance between the two sides of the outlet of the outlet end 343 in the height direction is H, and D < H < 2D, so that H is greater than D to enable the rotor shaft 1 to be discharged from the storage bin 34 through the outlet of the outlet end 343, and H is less than 2D to prevent two or more rotor shafts 1 from being simultaneously discharged from the outlet, thereby reducing the risk that the simultaneous discharge of multiple rotor shafts 1 from the outlet of the outlet end 343 to the storage bin 34 causes the rotor shafts 1 to be stacked together at the outlet end 343, preventing the situation that multiple rotor shafts 1 are stacked and move to the lifting platform 35, i.e., preventing the lifting platform 35 from transporting two or more rotor shafts 1 to the discharge position, ensuring that the first ejection assembly 33 applies a pushing force to only one rotor shaft 1 at a time to eject it from the storage mechanism 3, improving the accuracy of the use of the rotor shaft 1, and reducing the risk of unqualified motor rotors produced, thereby reducing the unqualified rate of motor rotors in the production and processing.

[0054] Embodiment 2:

[0055] Different from embodiment 1 is that the discharge position is not located on the lifting platform 35;

[0056] With reference to Figure 6 , the storage rack 31 is fixedly connected with a discharge table 312 corresponding to the discharge position, the discharge table 312 and the outlet end 343 are located on the two sides of the support area 351 respectively, the side of the support area 351 facing the discharge table 312 is arranged in an open manner, and when the lifting platform 35 is in the second position, the bottom surface height of the support area 351 is higher than that of the discharge table 312, so that the rotor shaft 1 in the support area 351 can enter the discharge table 312, and the remaining structures are the same as in the embodiment.

[0057] The implementation principle of the motor rotor shaft automatic feeding equipment in embodiment 2 of the present application is as follows:

[0058] After the lifting platform 35 moves to the second position, since the support area 351 is arranged in an open manner towards the side of the outlet platform 312, when the lifting platform 35 is in the second position, the bottom surface height of the support area 351 is higher than the bottom surface height of the outlet platform 312, the rotor shaft 1 on the support area 351 will accurately enter the outlet platform 312 due to the action of its own gravity, that is, the rotor shaft 1 can accurately enter the outlet position, so that the first ejection assembly 33 corresponding to the outlet position can accurately eject the rotor shaft 1 from the storage mechanism 3, preventing the first ejection assembly 33 from being unable to eject the rotor shaft 1 due to the deviation of the rotor shaft 1 from the outlet position, reducing the risk of affecting the subsequent removal and processing of the rotor shaft 1 due to the inability of the rotor shaft 1 to be ejected, and improving the stability of the equipment use.

[0059] Embodiment 3:

[0060] Based on Embodiment 1 of the present application:

[0061] Referring to Figure 5 and Figure 6 , the outlet end 343 is provided with a buffer platform 313, which is located between the lifting platform 35 and the outlet end 343 and is installed on the storage rack 31 in a liftable manner. The buffer platform 313 has a buffer area 3131, which is arranged in an open manner towards a first side 3132 of the outlet end 343 and a second side 3133 of the lifting platform 35, the bottom surface height of the buffer area 3131 decreases from the first side 3132 to the second side 3133, the buffer platform 313 has a third position and a fourth position, when the buffer platform 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 platform 313 is in the fourth position and the lifting platform 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 platform 35, the storage rack 31 is provided with a second lifting driving member for driving the buffer platform 313 to switch between the third position and the fourth position, the second lifting driving member adopts a conventional driving cylinder, one end of the piston rod of the second lifting driving member is fixedly connected to the buffer platform 313 and the other end is fixedly connected to the storage rack 31.

[0062] The implementation principle of Embodiment 3 of the motor rotor shaft 1 automatic feeding equipment is:

[0063] When the rotor shaft 1 is discharged from the outlet of the outlet end 343 out of the storage bin 34, 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, wherein the bottom surface height of the buffer area 3131 decreases from the first side 3132 to the second side 3133, so that the rotor shaft 1 of the plurality of outlet ends 343 moves from the outlet end 343 to the buffer area 3131, and after reaching the buffer area 3131, it moves from the first side 3132 to the second side 3133 of the buffer area 3131 until it is full, and then the second lifting drive 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 when the lifting table 35 is in the first position, so that the rotor shaft 1 closest to the lifting table 35 on the buffer area 3131 moves to the lifting table 35 in the first position, and then the lifting table 35 is driven by the first lifting drive to switch from the first position to the second position to transport the rotor shaft 1 to the discharge position, and finally the rotor shaft 1 is ejected from the storage mechanism 3 by the first ejection assembly 33, and then the empty lifting table 35 is driven by the first lifting drive to switch from the second position to the first position, and another rotor shaft 1 on the buffer area 3131 moves to the lifting table 35 again, and then the lifting table 35 transports this rotor shaft 1 to the discharge position, and the rotor shaft 1 is ejected by the first ejection assembly 33, and so on, until the last rotor shaft 1 on the buffer table 313 moves to the empty lifting table 35, at this time the first lifting drive assembly drives the lifting table 35 to switch positions, and the second lifting drive assembly drives the empty buffer table 313 to switch from the fourth position to the third position, so that the rotor shaft 1 of the outlet end 343 enters the buffer area 3131 again, and after the rotor shaft 1 fills the buffer area 3131, the buffer table 313 is driven by the second lifting drive to switch from the third position to the fourth position, and so on to realize the one-by-one ejection of the rotor shaft 1 from the storage mechanism 3. Wherein the buffer table 313 is used to transport a plurality of rotor shafts 1 from the third position to the fourth position, and then one by one into the lifting table 35, so as to realize the synchronous movement of a plurality of rotor shafts 1 in part of the time, and at the same time, the required distance between the first position and the second position of the lifting table 35 is shortened, that is, the time required for the lifting table 35 to switch from the first position to the second position is shortened, and the switching of the lifting table 35 position and the switching of the buffer table 313 position can be synchronized, thereby shortening the time required to take out a large number of rotor shafts 1, and improving the efficiency of the equipment for taking out the rotor shaft 1.

[0064] Referring to Figure 5 and Figure 6In order to reduce the risk of emptying the lifting platform 35 and the buffer platform 313, the buffer area 3131 is arranged close to the lifting platform 35, so that when the buffer platform 313 is in the third position and the lifting platform 35 is in the second position, the rotor shaft 1 in the buffer area 3131 is close to the side wall of the lifting platform 35, the side wall hinders the movement of the rotor shaft 1 in the direction away from the outlet end 343, reduces the risk that the rotor shaft 1 moves in the direction away from the outlet end 343 after moving into the buffer area 3131 and falls from the buffer area 3131 to the lifting platform 35, that is, reduces the risk of emptying the lifting platform 35, prevents the lifting platform 35 from being empty and affecting the efficiency of the equipment for taking the rotor shaft 1, and improves the stability of the equipment.

[0065] With reference to Figure 1 and Figure 7 In order to ensure that there are at least two rotor shafts 1 in the buffer area 3131 each time the buffer platform 313 switches from the third position to the fourth position, the diameter of the rotor shaft 1 is D, the width of the buffer area 3131 is L2, L2≥2D, that is, the width L2 of the buffer area 3131 is greater than or equal to 2D, so that the buffer area 3131 can accommodate at least two rotor shafts 1, so as to ensure that there are at least two rotor shafts 1 in the buffer area 3131 each time the buffer platform 313 switches from the third position to the fourth position, reduces the risk that the buffer platform 313 transports only one rotor shaft 1 each time, reduces the efficiency of the equipment for taking the rotor shaft 1, and improves the stability of the equipment.

[0066] Embodiment 4:

[0067] Based on embodiment 1:

[0068] With reference to Figure 1 and Figure 8 The taking mechanism 4 comprises a moving frame 41 slidably connected to the fixed frame 2, a moving mechanism for driving the moving frame 41 to move, a second ejection assembly and four hollow pipes 43 mounted on the moving frame 41, one end of the hollow pipe 43 is towards the outlet position, and the second ejection assembly is mounted on the other end of the hollow pipe 43 and is used for ejecting the rotor shaft 1 in the hollow pipe 43. The second ejection assembly comprises a first cylinder and a pushing rod, one end of the piston rod of the first cylinder is fixedly connected with the pushing rod, and the other end is fixedly connected to the moving frame 41. The moving mechanism comprises a sliding rail mounted on the moving frame 41, a transmission screw rod rotatably connected to the fixed frame 2, a first motor mounted on the fixed frame 2 and used for driving the transmission screw rod to rotate, and a sliding block mounted on the moving frame 41. The sliding block is in sliding cooperation with the sliding rail to limit the rotation of the sliding block, and the sliding block is threadedly connected to the transmission screw rod.

[0069] The implementation principle of the motor rotor shaft automatic feeding equipment in embodiment 4 of the present application is:

[0070] When the lifting platform 35 is switched from the first position to the second position, the corresponding one rotor shaft 1 is in the discharging position, the moving mechanism drives the moving frame 41 to translate, that is, the first motor drives the transmission screw rod to rotate, so that the sliding block slides in the extension direction of the transmission screw rod, that is, the translation of the moving frame 41 is realized, so that one end of the hollow tube 43 is opposite to the discharging position. At this time, the first ejection assembly 33 applies a pushing force to the rotor shaft 1 to move it in the direction close to the hollow tube 43, so that the rotor shaft 1 is integrally moved from the discharging position to the inner cavity of the hollow tube 43. If there are multiple hollow tubes 43, the moving mechanism drives the moving frame 41 to translate to make another hollow tube 43 opposite to the discharging position. This cycle is repeated to realize the one-by-one taking out of the rotor shaft 1. After four rotor shafts 1 are in 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. Then the second ejection assembly ejects the rotor shaft 1 in the hollow tube 43, so that the four rotor shafts 1 are transported at the same time while ensuring that the four rotor shafts 1 are taken out one by one, thereby improving the transportation efficiency of the taking-out mechanism 4 for the rotor shaft 1.

[0071] In order to ensure that the rotor shaft 1 is smoothly pushed onto the taking-out mechanism 4, the taking-out mechanism 4 further comprises a vacuum negative pressure assembly installed on the moving frame 41. The vacuum negative pressure assembly is in communication with the inner cavity of the hollow tube 43 to generate negative pressure in the inner cavity, so that when the first ejection assembly 33 applies a pushing force to the rotor shaft 1 to move it in the direction close to the hollow tube 43, the vacuum negative pressure assembly generates negative pressure in the inner cavity of the hollow tube 43 to generate suction force on the rotor shaft 1 due to the pressure difference, so that the rotor shaft 1 is integrally moved from the discharging position to the inner cavity of the hollow tube 43. This improves the probability of the rotor shaft 1 entering the hollow tube 43 completely, prevents the risk that the pushing force of the first ejection assembly 33 on the rotor shaft 1 is too small to cause the rotor shaft 1 to not enter the hollow tube 43 in some areas, and reduces the risk of empty loading of the hollow tube 43 affecting the transportation efficiency of the rotor shaft 1 and the risk of the rotor shaft 1 not being smoothly taken out affecting subsequent processing, thereby improving the stability of equipment use.

[0072] Embodiment 5:

[0073] Based on embodiment 1:

[0074] Referring to Figure 9 , Figure 1 and Figure 8 , one end of the rotor shaft 1 is provided with a groove 11, a detection mechanism 5 for detecting whether the rotor shaft 1 is in the correct direction is installed between the storage mechanism 3 and the taking-out mechanism 4, and a rotor shaft 1 recovery box is installed below the detection mechanism 5.

[0075] Referring to Figure 9 , Figure 1 and Figure 8, the first ejection assembly 33 pushes the rotor shaft 1 on the discharging position to the detection mechanism 5, the 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 taking mechanism 4 moves to the receiving position, the first ejection assembly 33 pushes the rotor shaft 1 on the detection mechanism 5 to the taking mechanism 4, if the detection result of the detection mechanism 5 is negative, the taking mechanism 4 is located at the initial position, and the first ejection assembly 33 pushes the rotor shaft 1 on the detection mechanism 5 to fall into the rotor shaft 1 recycling box. The initial position is a position where the taking mechanism 4 cannot receive the rotor shaft 1 on the detection mechanism 5.

[0076] With reference to Figure 9 、 Figure 10 and Figure 11 , the taking mechanism 4 is located on the left side of the rotor shaft 1, the first ejection assembly 33 pushes the rotor shaft 1 from left to right to the detection mechanism 5, the rotor shaft 1 in the positive direction is that the groove 11 is located on the side of the rotor shaft 1 close to the taking mechanism 4, and the rotor shaft 1 in the negative direction is that the groove 11 is located on the side of the rotor shaft 1 away from the taking mechanism 4.

[0077] The implementation principle of the motor rotor shaft automatic feeding equipment in the embodiment 5 is as follows:

[0078] The rotor shaft 1 is stored in the storage mechanism 3, the rotor shaft 1 in the positive direction is that the groove 11 of the rotor shaft 1 is located on the end of the rotor shaft 1 close to the storage mechanism 3, the rotor shaft 1 in the negative direction is that the groove 11 of the rotor shaft 1 is located on the end of the rotor shaft 1 away from the storage mechanism 3, the first ejection assembly 33 pushes the rotor shaft 1 on the discharging position to 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 information to the taking mechanism 4, if the rotor shaft 1 is in the positive direction, the taking mechanism 4 moves to the receiving position, the first ejection assembly 33 pushes the rotor shaft 1 on the detection mechanism 5 to the taking mechanism 4, so that the rotor shaft 1 in the positive direction can enter the taking mechanism 4, if the rotor shaft 1 is in the negative direction, the taking mechanism 4 remains in the initial position, and the first ejection assembly 33 pushes the rotor shaft 1 on the detection mechanism 5 to fall into the rotor shaft 1 recycling box, so that the rotor shaft 1 in the negative direction cannot enter the taking mechanism 4, that is, the detection mechanism 5 removes the rotor shaft 1 with the wrong direction before the rotor shaft 1 is pushed to the taking mechanism 4, so that the rotor shaft 1 taken by the taking mechanism 4 is in the same direction and in the positive direction, thereby reducing the risk of unqualified motor rotor caused by the wrong direction of the rotor shaft 1, and reducing the unqualified rate of the motor rotor in the production and processing.

[0079] With reference to Figure 12The first ejection assembly 33 further comprises 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 ejection shaft is installed at the telescopic end of the second telescopic driving member 332. The taking mechanism 4 is located at one side of the discharging position. The first telescopic driving member 331 and the second telescopic driving member 332 are both conventional driving cylinders. One end of the piston rod of the second telescopic driving member 332 is fixedly connected with the ejection shaft, and the other end is fixedly connected with 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 with the storage rack 31. When the first ejection assembly 33 pushes the rotor shaft 1 on the discharging position to the detection mechanism 5, the second telescopic driving member 332 is elongated, so that the ejection shaft moves in the opposite direction to the rotor shaft 1 on the discharging position and exerts a pushing force on the rotor shaft 1 to push it to the detection mechanism 5. When the first ejection assembly 33 needs to push the rotor shaft 1 on the detection mechanism 5 to the taking mechanism 4 or the rotor shaft 1 recycling box, the first telescopic driving member 331 is elongated, so that the ejection shaft exerts a pushing force on the rotor shaft 1 on the detection mechanism 5 again, so that the rotor shaft 1 is pushed to the 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 elongation rate of the second telescopic driving member 332 is relatively slow, so that the ejection shaft slowly pushes the rotor shaft 1 to enter the detection mechanism 5. When the rotor shaft 1 is pushed to the detection mechanism 5, there is a frictional force between the rotor shaft 1 and the detection mechanism 5. By making the rotor shaft 1 slowly slide to the detection mechanism 5, the inertial force of the rotor shaft 1 is less than the frictional force, so as to reduce the risk of the rotor shaft 1 deviating from the specified position due to inertia and improve the accuracy of the equipment.

[0080] Embodiment 6:

[0081] Based on Embodiment 5, the present application:

[0082] With reference to Figure 11 and Figure 12 The detection mechanism 5 comprises a mounting frame 51 fixedly connected with the fixed frame 2, a clamping mechanism 52 installed on the mounting frame 51 and used for clamping the rotor shaft 1 and clamping into the groove 11 on the rotor shaft 1, and a detection sensor 53 used for detecting whether the rotor shaft 1 exists on the mounting frame 51.

[0083] With reference to Figure 11 and Figure 12, the clamping mechanism 52 comprises a clamping driving assembly 7 mounted on the mounting frame 51 and clamping assemblies 8 slidably connected to the mounting frame 51, the mounting frame 51 is provided with a through hole 511, the number of the clamping assemblies 8 is four, the four clamping assemblies 8 are arranged in a circumferential direction and spaced apart from each other along 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 clamped into the groove 11 to limit the slippage of the rotor shaft 1 relative to the mounting frame 51, when the clamping mechanism 52 is in the unlocked state, the four clamping assemblies 8 are all loosened to enable the rotor shaft 1 to slip relative to the mounting frame 51, the clamping driving assembly 7 can drive the clamping assemblies 8 to slide away from or close to the through hole 511 to switch between the unlocked state and the locked state of the clamping mechanism 52.

[0084] With reference to Figure 11 and Figure 12 , the mounting frame 51 is provided with a sliding groove 512 communicating with the through hole 511, the clamping assembly 8 comprises a sliding frame 81 slidably connected to the sliding groove 512, a sliding block 82 slidably connected to the sliding frame 81 and an elastic member 83 located between the sliding frame 81 and the sliding block 82 and used to extend the sliding block 82 towards the through hole 511, the elastic member 83 is 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.

[0085] With reference 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 clamped into the groove 11 to limit the slippage of the rotor shaft 1 relative to the mounting frame 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 to enable the rotor shaft 1 to slip relative to the mounting frame 51.

[0086] With reference to Figure 13 and Figure 14 , the detection sensor 53 comprises 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 frame 51 and located on opposite sides of the through hole 511, even when the rotor shaft 1 is located on the mounting frame 51, i.e. the rotor shaft 1 is arranged in 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, so that the laser receiving end 531 cannot receive the laser, when the rotor shaft 1 is not located on the mounting frame 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, so that the detection sensor 53 can determine whether the rotor shaft 1 is present on the mounting frame 51 at the moment.

[0087] The embodiment 6 of the application is a motor rotor shaft automatic feeding device, and the implementation principle is as follows:

[0088] When the second telescopic driving member 332 is elongated, the rotor shaft 1 at the discharging position is pushed to the detection mechanism 5 as a whole, i.e., the rotor shaft 1 is pushed to the mounting frame 51 as a whole, and the rotor shaft 1 is pushed to the specified position corresponding to the clamping mechanism 52 on the mounting frame 51, and then the clamping mechanism 52 clamps the rotor shaft 1 after reaching the specified position. That is, the clamping driving assembly 7 drives the clamping assembly 8 to slide towards the direction close to the through hole 511 to switch the clamping mechanism 52 from the unlocking state to the locking state. If the rotor shaft 1 is forward, the four sliding blocks 82 all abut against the rotor shaft 1, and one of the sliding blocks 82 is clamped into the groove 11 to limit the sliding of the rotor shaft 1 relative to the mounting frame 51. If the rotor shaft 1 is reverse, since the position of the groove 11 of the reverse rotor shaft 1 is inconsistent with that of the forward rotor shaft 1, the groove 11 on the reverse rotor shaft 1 will deviate from the specified position of the clamping mechanism 52, i.e., each sliding block 82 will abut against the circumferential side wall of the reverse rotor shaft 1 to clamp the rotor shaft 1, but none of the sliding blocks 82 will be clamped into the groove 11 of the rotor shaft 1. After the clamping mechanism 52 clamps the rotor shaft 1, the first ejection assembly 33 will again apply a pushing force to the rotor shaft 1 on the mounting frame 51, i.e., the first telescopic driving member 331 is elongated. Since one of the sliding blocks 82 is clamped into the groove 11 of the forward rotor shaft 1, the sliding block 82 will apply a pushing force to the groove wall of the groove 11 to prevent the sliding of the rotor shaft 1. Since the circumferential side wall of the rotor shaft 1 is relatively smooth, the friction between the rotor shaft 1 and the sliding block 82 is small, and the reverse rotor shaft 1 will be pushed off from the mounting frame 51. At this time, the material taking mechanism 4 is located at the initial position, and the reverse rotor shaft 1 will fall into the rotor shaft 1 recovery box. After the first telescopic driving member 331 acts for a period of time, it is ensured that the reverse rotor shaft 1 falls into the rotor shaft 1 recovery box. The data of the detection sensor 53 at this moment is read and the information is fed back to the material taking mechanism 4. If the rotor shaft 1 is reverse, the detection sensor will detect that there is no rotor shaft 1 on the mounting frame 51 at this moment, and the material taking mechanism 4 will remain at the initial position. If the rotor shaft 1 is forward, the detection sensor detects that there is a rotor shaft 1 on the mounting frame 51 at this moment, and the material taking mechanism 4 will move from the initial position to the receiving position. Then the clamping driving assembly 7 drives the clamping assembly 8 to move away from the through hole 511 to switch the clamping mechanism 52 from the locking state to the unlocking state, and the clamping of the rotor shaft 1 is cancelled. For the forward rotor shaft 1, the sliding block 82 is no longer clamped into the groove 11, i.e., the sliding block 82 no longer applies a pushing force to the groove wall of the groove 11, so that the first telescopic driving member 331 can be elongated to apply a pushing force to the rotor shaft 1 again. Since the material taking mechanism 4 has moved to the receiving position, the rotor shaft 1 is pushed to the material taking mechanism 4, i.e., the forward rotor shaft 1 is pushed to the material taking mechanism 4. The cooperation of the clamping mechanism 52 and the groove 11 of the rotor shaft 1 enables the rotor shaft 1 with the wrong direction to be automatically pushed into the rotor shaft 1 recovery box without manual operation, thereby improving the convenience of using the equipment.The number of the clamping assemblies 8 is four, and they are arranged along the circumference of the through hole 511, so that the clamping assemblies 8 cannot be clamped into the groove 11 due to the deviation of the rotor shaft 1 from the clamping assemblies 8, the accurate rotor shaft 1 cannot be pushed to the taking mechanism 4 due to the clamping assemblies 8 cannot be clamped into the groove 11, and the accuracy of the detection mechanism 5 is improved. The elastic member 83 plays a certain guiding role in the sliding process of the sliding block 82, prevents the sliding path of the sliding block from deviating and affecting the clamping of the rotor shaft 1, and improves the stability of the equipment.

[0089] In order to prevent the sliding block 82 from abutting with the rotor shaft 1 and causing damage to the rotor shaft 1, the sliding block 82 is made of soft metal material such as copper, so as to reduce the risk of damage to the rotor shaft 1 caused by the abutting of the sliding block 82.

[0090] Referring to Figure 15 , Figure 11 and Figure 12Further, the clamping driving assembly 7 comprises a rotating frame 71 rotatably connected to the mounting frame 51 and a rotating driving member 72 mounted on the mounting frame 51 and used for driving the rotating frame 71 to rotate, the rotating frame 71 is provided with a plurality of arc-shaped grooves 711 corresponding to the sliding blocks 82 respectively, the sliding frame 81 is fixedly connected with a guide member 811 used for extending into the corresponding arc-shaped groove 711, the guide member 811 is a guide rod 8111 penetrating through the sliding frame 81, the groove wall of the sliding groove 512 is provided with a guide groove 5121 corresponding to the sliding block respectively, one end of the guide rod 8111 is slidably connected in the arc-shaped groove 711 and the other end is slidably connected in the guide groove 5121. The rotating driving member 72 adopts a conventional driving cylinder, one end of the rotating driving member 72 is hingedly connected to the mounting frame 51 and the other end is hingedly connected to the rotating frame 71. The extension direction of the guide groove 5121 is the extension direction of the aperture diameter of the through hole 511, the arc-shaped groove 711 is eccentrically arranged relative to the rotating shaft of the rotating frame 71, so that the guide rod 8111 moves away from or close to the through hole 511 under the guidance of the arc-shaped groove 711 when the rotating frame 71 rotates relative to the mounting frame 51. The arc-shaped groove 711 is eccentrically arranged relative to the rotating shaft of the rotating frame 71, so the distance between the two ends of the arc-shaped groove 711 and the rotating shaft is not the same, when it is needed to make the sliding block 82 rotate away from or close to the through hole 511, the rotating driving member 72 is extended or retracted to drive the rotating frame 71 to rotate relative to the mounting frame 51, the arc-shaped groove 711 applies a pushing force to the guide rod 8111 to make the guide rod 8111 slide, since the other end of the guide rod 8111 is slidably connected in the guide groove 5121, the extension direction of the guide groove 5121 is the extension direction of the aperture diameter of the through hole 511, that is, the groove wall of the guide groove 5121 will limit the sliding direction of the guide rod 8111, so that the plurality of guide rods 8111 simultaneously move away from or close to the through hole 511, that is, the plurality of sliding blocks simultaneously move away from or close to the through hole 511, that is, the movement of the plurality of clamping assemblies 8 is realized by driving the rotating frame 71 to rotate through the rotating driving member 72, without driving the clamping assemblies 8 one by one, the operation is convenient and fast, and the convenience of using the equipment is improved. At the same time, only one power source, the rotating driving member 72, is used, which reduces the use cost of the equipment.

[0091] With reference to ​ and ​, preferably, every two oppositely arranged clamping assemblies 8 form a first assembly 84 and a second assembly 85, when the clamping assemblies 8 are in the unlocked state, the distance between the sliding block 82 in the first assembly 84 and the wall of the through hole 511 near the end of the through hole 511 is S1, the distance between the sliding block 82 in the second assembly 85 and the wall of the through hole 511 near the end of the through hole 511 is S2, S1 < S2, when the sliding block 82 in the second assembly 85 abuts against the circumferential side wall of the rotor shaft 1, the elastic force of the elastic member 83 in the second assembly 85 is F1, the elastic force of the elastic member 83 in the first assembly 84 is F2, F1 > F2. If the angle of the groove 11 of the forward rotor shaft 1 deviates from the clamping assembly 8, when the clamping mechanism 52 is used to clamp the rotor shaft 1, that is, the clamping mechanism 52 is switched from the unlocked state to the locked state, during this process, because S1 is less than S2, the sliding block 82 in the first assembly 84 will first abut against the circumferential side wall of the rotor shaft 1, and one of the sliding blocks 82 is partially located in the slot of the groove 11 of the rotor shaft 1, and then the sliding block 82 in the second assembly 85 abuts against the circumferential side wall of the rotor shaft 1, and one of the sliding blocks 82 is also partially located in the slot of the groove 11, because F1 is greater than F2, and the surface of the rotor shaft 1 is smooth, the sliding block 82 in the second assembly 85 will push the rotor shaft 1 to rotate, until the corresponding sliding block 82 in the second assembly 85 is clamped into the groove 11, thereby achieving clamping of the forward rotor shaft 1 and limiting the sliding of the forward rotor shaft 1 relative to the mounting frame 51, reducing the situation that the clamping assembly 8 cannot be clamped into the groove 11, resulting in that the correctly oriented rotor shaft 1 cannot be pushed to the taking mechanism 4, and improving the accuracy of the use of the detection mechanism 5.

[0092] Further, F1 is always greater than F2 during the process of switching the clamping mechanism 52 from the unlocked state to the locked state, thereby ensuring that the sliding block 82 in the second assembly 85 can push the rotor shaft 1 clamped by the sliding block 82 in the first assembly 84, reducing the situation that the clamping assembly 8 cannot be clamped into the groove 11, resulting in that the correctly oriented rotor shaft 1 cannot be pushed to the taking mechanism 4, and further improving the accuracy of the use of the detection mechanism 5.
