Motor magnetic ring feeder Technical Field

[0001] This invention relates to the field of feeding equipment technology, and in particular to a motor magnetic ring feeder. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. With the continuous development of motor manufacturing technology, higher requirements have been placed on the motor manufacturing process. As one of the important components of a motor, the magnetic ring is crucial to the final quality of the motor product at every stage of its production. For example, during magnetic ring assembly, the magnetic ring needs to be loaded and assembled into the motor housing. Traditionally, the loading of magnetic rings still largely relies on manual labor. However, manual loading is easily affected by human factors, leading to low efficiency and inaccuracy. In other words, deviations in the magnetic ring loading position will directly affect the assembly accuracy of the motor.

[0003] In view of the above, a motor magnetic ring feeder is proposed to realize automated feeding of motor magnetic rings, thereby improving production efficiency and feeding accuracy. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a motor magnetic ring feeder that can improve production efficiency and magnetic ring feeding alignment accuracy.

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

[0006] A magnetic ring feeding machine for motors includes: a rotary discharge module, a material picking and positioning module, and a feeding and alignment robot. The rotary discharge module includes a base, a rotary discharge device, and a rotary drive component. The rotary discharge device is disposed on the base, and the rotary drive component is connected to the rotary discharge device. The rotary drive component is used to drive the rotary discharge device to perform a rotary discharge operation. The material picking and positioning module includes a positioning fixture and a material picking device. The positioning fixture is disposed on the base, and the material picking device is located on one side of the positioning fixture. The rotary discharge device has a material picking end on the side closest to the positioning fixture. The material picking device is used to transfer the magnetic ring located on the material picking end to the positioning fixture. The feeding and alignment robot is located on one side of the material picking and positioning module. The feeding and alignment robot is used to perform feeding and alignment operations on the magnetic ring on the positioning fixture.

[0007] In one embodiment, a discharge identification device is also included. The discharge identification device is disposed on the base and the identification sensing end of the discharge identification device faces the material picking end. The discharge identification device is used to perform discharge identification operation on the magnetic ring on the material picking end.

[0008] In one embodiment, the discharge identification device is an optical fiber sensor.

[0009] In one embodiment, the positioning fixture includes a fixing block and a positioning block. The fixing block is disposed on the base, and the positioning block is disposed on the fixing block. When the material picking device is used to transfer the magnetic ring located on the material picking end to the positioning block, the positioning block is used to perform a positioning operation on the magnetic ring.

[0010] In one embodiment, the positioning block is provided with a positioning boss, and the material picking device is used to transfer the magnetic ring located on the material picking end and sleeve it on the positioning boss.

[0011] In one embodiment, the positioning block is made of a non-metallic buffer material.

[0012] In one embodiment, the material handling device includes a material handling gripper and a displacement drive. The displacement drive is mounted on the base, and the material handling gripper is connected to the displacement drive. The displacement drive is used to drive the material handling gripper to reciprocate between the material handling end and the positioning fixture.

[0013] In one embodiment, the material gripper includes a gripper drive and a gripper body, the gripper body being connected to the gripper drive, and the gripper drive being used to drive the gripper body to perform an opening and closing gripping operation.

[0014] In one embodiment, a buffer limiting block is provided on the contact side of the gripper body and the magnetic ring.

[0015] In one embodiment, the loading and alignment robot includes a support, an alignment conveying module, and a loading gripper. The alignment conveying module is disposed on the support, and the loading gripper is connected to the alignment conveying module. The alignment conveying module is used to drive the loading gripper to perform loading and alignment operations on the magnetic ring on the positioning fixture.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] The motor magnetic ring feeding machine of the present invention is equipped with a rotary discharge module, a material picking and positioning module, and a feeding and alignment robot. The rotary discharge module automatically rotates and discharges the magnetic rings, and the material picking device transports the magnetic rings to the positioning fixture to achieve the positioning operation of the magnetic rings. This facilitates the subsequent feeding and alignment operation of the magnetic rings on the positioning fixture by the feeding and alignment robot. In other words, the feeding and alignment robot realizes the alignment and assembly of the magnetic rings with the motor housing. In this way, manual intervention can be reduced, and the feeding of motor magnetic rings can be automated, thereby improving production efficiency and the accuracy of feeding and alignment.

[0024] To facilitate understanding of the present invention, a more comprehensive description of the invention will be given below with reference to the accompanying drawings.

[0025] Referring to Figures 1, 2, 3, 4, and 5, a motor magnetic ring feeder 10 includes: a rotary discharge module 100, a material picking and positioning module 200, and a feeding and positioning robot 300. The rotary discharge module 100 includes a base 110, a rotary discharge device 120, and a rotary drive 130. The rotary discharge device 120 is mounted on the base 110, and the rotary drive 130 is connected to the rotary discharge device 120, driving the rotary discharge device 120 to perform a rotary discharge operation. The material picking and positioning module 200... The 00 includes a positioning fixture 210 and a material handling device 220. The positioning fixture 210 is mounted on the base 110, and the material handling device 220 is located on one side of the positioning fixture 210. The rotating discharge device 120 has a material handling end on the side near the positioning fixture 210. The material handling device 220 is used to transfer the magnetic ring located on the material handling end to the positioning fixture 210. The loading and alignment robot 300 is located on one side of the material handling and positioning module 200. The loading and alignment robot 300 is used to load and align the magnetic ring on the positioning fixture 210.

[0026] It should be noted that the rotary feeding device 120 is used to store magnetic rings. When feeding the motor magnetic rings, the magnetic rings on the rotary feeding device 120 move to the picking end. Then, the picking device 220 moves to the picking end and transports the magnetic rings on the picking end to the positioning fixture 210. The positioning fixture 210 positions the magnetic rings to ensure that the subsequent feeding and alignment robot can accurately pick up the magnetic rings. Then, the feeding and alignment robot 300 transports the magnetic rings on the positioning fixture 210 to the loading fixture of the corresponding assembly equipment. The feeding and alignment robot 300 aligns and combines the magnetic rings with the motor housing. In this way, human intervention can be reduced, and automatic feeding and alignment operations of the motor magnetic rings can be realized, thereby improving production efficiency and the accuracy of feeding, alignment and assembly.

[0027] Traditional material discharge methods typically involve vibration discharge, where materials are stored in a vibratory feeder and discharged one by one through vibration. However, due to the magnetic properties of the magnetic rings, vibration discharge presents several problems. For instance, since the magnetic rings are placed in batches on the vibratory feeder, they tend to stick together, preventing them from being discharged one by one. Furthermore, the frequent contact between the magnetic rings and the metal vibratory feeder during vibration can alter their magnetism, such as weakening their magnetic properties, which in turn affects the quality of the motor. Therefore, this invention addresses the magnetic ring discharge problem by replacing the existing vibratory feeder with a rotary discharge module 100.

[0028] Please refer to Figures 1, 2, 3, and 4. Specifically, the rotary discharge device 120 includes a rotary table 121, a rotary column 122, a rotary fixed disk 123, and multiple storage pipes 124. The rotary column 122 is disposed on the central axis of the rotary table 121, and the rotary fixed disk 123 is sleeved on the rotary column 122. Each of the storage pipes 124 is arranged in an array on the rotary fixed disk 123 with the rotary column 122 as the central axis. The rotary drive 130 is connected to the rotary table 121 and is used to drive the rotary table 121 to rotate, so that each of the storage pipes 124 rotates.

[0029] It should be noted that multiple magnetic rings are stored on the storage pipe 124 in a stacked manner. The magnetic rings are stored and discharged one by one through the storage pipe 124. Each storage pipe 124 is provided with a discharge gap between it and the rotary table 121. Each discharge gap allows only one magnetic ring to be discharged. The magnetic rings coming out of the storage pipe 124 are located on the rotary table 121. The rotary drive 130 drives the rotary table 121 to rotate, so that one of the storage pipes 124 moves to the front of the positioning fixture 210 and the discharge gap of the storage pipe 124 coincides with the picking end. Thus, the picking device 220 can pick up the magnetic rings at the picking end and transport them to the positioning fixture 210. Since the discharge gap only allows one magnetic ring to be discharged at a time, it ensures that the magnetic rings are discharged one by one, avoiding the removal of multiple magnetic rings during picking. In this embodiment, the motor magnetic ring feeder 10 also includes a discharge identification device 400, which is mounted on the base 110 with its identification sensing end facing the picking end. The discharge identification device 400 is used to identify the magnetic rings on the picking end. The discharge identification operation is performed. For example, the discharge identification device is a fiber optic sensor. When all the magnetic rings in the storage pipe 124 at the material receiving end are removed, the fiber optic sensor identifies that there are no magnetic rings at the material receiving end, and then transmits a signal to the control terminal. The control terminal starts the rotary drive 130, and then the rotary drive 130 continues to drive the rotary table 121 to rotate, so that the next storage pipe 124 filled with magnetic rings moves to the top of the material receiving end and continues to discharge magnetic rings. In this way, since there are multiple storage pipes 124, the number of magnetic rings that can be stored can be increased, the number of times the feeder stops to feed can be reduced, thereby improving the feeding efficiency. In addition, the use of rotation also makes the overall structure of the rotary discharge device 120 more compact. Furthermore, the external shape of the storage pipe 124 matches the external shape of the magnetic ring. In this embodiment, the magnetic ring has a circular shape, so the storage pipe 124 also has a circular shape. However, the external shape of the magnetic ring is not limited to the circular shape mentioned in this invention. In another embodiment, when the feeding efficiency requirement is not high, the storage pipe 124 can be a single storage pipe 124. In this way, the rotary drive component 130 does not need to be provided, thereby making the overall equipment structure simpler and more compact. In this embodiment, the rotary drive component 130 adopts a motor belt drive structure. For example, the motor belt structure includes a reducer, a motor, and a belt.

[0030] In one embodiment, to facilitate the installation of the storage pipe 124 onto the rotating fixed disk 123, and to ensure the positioning accuracy of the rotating fixed disk 123 on the storage pipe 124, thus preventing the installation position of the storage pipe 124 from shifting and causing the subsequent material handling device 220 to fail to handle the material properly, the rotating fixed disk 123 is provided with multiple limiting protrusions 123a. Each limiting protrusion 123a is arranged in an array around the rotating column 122 as its central axis, and a limiting gap is formed between two limiting protrusions 123a. The storage pipe 124 is located within the limiting gap. Thus, by positioning the storage pipe 124 through the limiting gap, the installation position of the storage pipe 124 can be prevented from shifting.

[0031] Furthermore, to further ensure the stability of the storage pipe 124 installation, a limiting plate 124a is provided on the storage pipe 124. When the storage pipe 124 is located within the limiting gap, the limiting plate 124a abuts against the upper surface of the limiting protrusion 123a. For example, the limiting plate 124a and the limiting protrusion 123a can be connected and fixed by screws or bolts to achieve the stability of the storage pipe 124 installation. Furthermore, in this embodiment, to further ensure the stability of the storage pipe 124 installation, multiple rotating fixing discs 123 are provided; that is, the longer the storage pipe 124, the more rotating fixing discs 123 are provided.

[0032] Furthermore, in order to enable the magnetic rings to be quickly transferred into the storage pipe 124, an avoidance notch 124b is provided on the feed end of the storage pipe 124. This increases the opening space at the feed end, making it easier to quickly load the magnetic rings into the storage pipe 124 in batches.

[0033] In one embodiment, the rotary table 121 is provided with a plurality of guide grooves 121a. The discharge end of each storage pipe 124 is aligned with each guide groove 121a. After the magnetic ring comes out of the storage pipe 124, it will enter the guide groove 121a. In this way, when the material picking device 220 picks up the magnetic ring, the magnetic ring moves along the guide groove 121a, thereby avoiding large positional displacement of the magnetic ring.

[0034] Furthermore, to prevent the magnetic ring from adhering to the storage pipe 124 and affecting the discharge, the storage pipe 124 is made of a non-metallic cushioning material, such as plastic. Similarly, the rotary table 121 is also made of a non-metallic material, such as plastic, which can also prevent the magnetic ring from being damaged by collision with the rotary table.

[0035] In one embodiment, the positioning fixture 210 includes a fixing block 211 and a positioning block 212. The fixing block 211 is disposed on the base 110, and the positioning block 212 is disposed on the fixing block 211. When the material picking device 220 is used to transfer the magnetic ring located on the picking end to the positioning block 212, the positioning block 212 is used to perform a positioning operation on the magnetic ring.

[0036] It should be noted that since the rotary discharge module 100 discharges material from the bottom, the loading and alignment robot 300 cannot properly grip the magnetic ring. Therefore, the magnetic ring needs to be gripped by the picking device 220 and placed on the positioning block 212 for temporary positioning. This facilitates the loading and alignment robot's gripping operation on the positioning block 212, ensuring that the subsequent loading and alignment robot accurately aligns and assembles the magnetic ring with the motor housing. In this embodiment, the positioning block 212 is provided with a positioning boss 212a. The picking device 220 is used to transfer the magnetic ring located at the picking end and fit it onto the positioning boss 212a; that is, the size of the positioning boss 212a matches the inner circle size of the magnetic ring, and the magnetic ring is positioned by the positioning boss 212a.

[0037] Furthermore, to prevent the magnetic ring from colliding and being damaged by the positioning boss 212a, the positioning block 212 is made of a non-metallic buffer material, such as rubber.

[0038] In one embodiment, the material handling device 220 includes a material handling gripper 221 and a displacement drive 222. The displacement drive 222 is mounted on the base 110. The material handling gripper 221 is connected to the displacement drive 222. The displacement drive 222 is used to drive the material handling gripper 221 to reciprocate between the material handling end and the positioning fixture 210.

[0039] It should be noted that in this embodiment, the displacement drive 222 is a slide cylinder, and the material picker 221 is set on the moving end of the slide cylinder. The slide cylinder drives the material picker 221 to move in the direction of the rotating discharge device 120. Specifically, in this embodiment, the material-grabbing gripper 221 includes a gripper drive 221a and a gripper body 221b. The gripper body 221b is connected to the gripper drive 221a, and the gripper drive 221a is used to drive the gripper body 221b to perform opening and closing gripping operations. The gripper body 221b consists of two gripping blocks, and the gripper drive 221a is a gripper cylinder. The gripper cylinder has two drive ends, and the two gripping blocks are respectively connected to the two drive ends. The gripper cylinder drives the two gripping blocks to perform opening and closing gripping operations. Furthermore, in order to ensure that the two gripping blocks do not deviate during the opening and closing gripping operations, the material-grabbing gripper 221 also includes a guide rod 221c. The guide rod 221c is respectively passed through the two gripping blocks. The guide rod 221c can ensure that the two gripping blocks do not shift position during the gripping action.

[0040] In one embodiment, a buffer limiting block 221d is provided on the contact side of the gripper body 221b and the magnetic ring. That is, a buffer limiting block 221d is provided on the contact side of both gripping blocks and the magnetic ring. For example, the buffer limiting block 221d is made of rubber. In this way, damage to the magnetic ring can be avoided when the gripper body 221b grips the magnetic ring.

[0041] Please refer to Figure 5. In one embodiment, the loading and alignment robot 300 includes a support 310, an alignment and conveying module 320, and a loading gripper 330. The alignment and conveying module 320 is disposed on the support 310, and the loading gripper 330 is connected to the alignment and conveying module 320. The alignment and conveying module 320 is used to drive the loading gripper 330 to perform loading and alignment operations on the magnetic ring on the positioning fixture 310.

[0042] It should be noted that the bracket 310 includes a support plate 311 and a reinforcing plate 312. The reinforcing plate 312 is disposed on one side of the support plate 311. The reinforcing plate 312 ensures the stability of the support plate 311. In this embodiment, the support plate 311 has an "L" shaped structure. The displacement conveying module 320 is installed on the support plate 311, and the support plate 311 supports and fixes the displacement conveying module 320. Furthermore, the displacement module 320 includes a transverse transfer component 321 and a lifting component 322. A transverse guide rail 313 is provided on the bracket 310. The transverse transfer component 321 is slidably disposed on the transverse guide rail 313. The lifting component 322 is connected to the transverse transfer component 321. The transverse transfer component 321 is used to drive the lifting component 322 to move laterally towards the positioning fixture 210. The lifting component 322 is connected to the loading gripper 330. The lifting component 322 drives the loading gripper 330 to move up and down, so that the loading gripper 330 can perform a gripping operation on the magnetic ring on the positioning fixture 210.

[0043] Specifically, the lateral moving component 321 includes a lateral cylinder 321a and a lateral sliding plate 321b. The lateral sliding plate 321b is slidably disposed on the lateral guide rail 313. The lateral cylinder 321a is connected to the lateral sliding plate 321b. The lateral cylinder 321a is used to drive the lateral sliding plate 321b to move towards the positioning fixture 210. The lateral guide rail 313 guides the lateral sliding plate 321b, thereby ensuring the stability of the movement of the lateral sliding plate 321b.

[0044] Furthermore, the lifting component 322 includes a lifting cylinder 322a and a lifting plate 322b. A lifting guide rail is provided on the transverse slide plate 321b, and the lifting plate 322b is slidably disposed on the lifting guide rail. The lifting cylinder 322a is connected to the lifting plate 322b. The lifting cylinder 322a is used to drive the lifting plate 322b to move up and down along the lifting guide rail, so that the loading gripper 330 moves up and down in the direction of approaching or moving away from the positioning fixture, thereby enabling the loading gripper 330 to perform a gripping operation on the magnetic ring on the positioning fixture.

[0045] Furthermore, the feeding gripper 330 includes a gripping cylinder 331 and a gripping component 332. The gripping component 332 is connected to the gripping cylinder 331, and the gripping cylinder 331 is used to drive the gripping component 332 to perform opening and closing gripping operations.

[0046] Specifically, the clamping component 332 includes a first clamping block and a second clamping block. A clamping cylinder 331 drives the first and second clamping blocks to move closer or further apart, thereby achieving the clamping and opening action. To prevent misalignment between the first and second clamping blocks, the clamping component 332 also includes a clamping guide rod, which passes through the first and second clamping blocks to prevent misalignment. Furthermore, a first limiting buffer block and a second limiting buffer block are respectively provided on the side of the first and second clamping blocks facing the magnetic ring. The first limiting buffer block has a limiting groove with an arc-shaped structure that matches the appearance of the magnetic ring. By providing the limiting groove, the contact area between the magnetic ring and the first and second clamping blocks can be increased, thereby ensuring stability when clamping the magnetic ring. In this embodiment, the first and second limiting buffer blocks have the same structure. For example, the first and second limiting buffer blocks can be made of cushioning rubber to prevent damage to the magnetic ring.

[0047] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
