Description

Technical Field

[0001] The present invention relates to the technical field of armature production, and in particular to a back-end production line for an armature commutator. Background Art

[0002] The armature in a brushless DC motor, also known as the rotor, is the core component that generates induced electromotive force and electromagnetic torque and realizes electromechanical energy conversion. The armature includes the armature core, armature winding, commutator, rotating shaft, etc. In the subsequent process of making the armature, it is necessary to test the conductivity of the commutator and winding. If the conductivity meets the requirements, the surface of the commutator needs to be polished to ensure that the smoothness of the commutator surface meets the usage standards. At present, the above-mentioned subsequent processes are usually completed manually. Even if they are not completed manually, they are completed separately by multiple production lines. The degree of manual participation is high and the degree of automation is low, which seriously affects the production efficiency of the armature. Summary of the Invention

[0003] In view of the above shortcomings in the prior art, the present invention provides an armature commutator back-end production line to solve the problem of low automation in the armature back-end production process, thereby improving the production efficiency of the armature.

[0004] To achieve the above-mentioned and other related purposes, the present invention provides an armature commutator back-end production line, which includes: A frame, along the conveying direction of the material, the frame is provided with a first detection station, a grinding station, and a second detection station in sequence; First conveyor line; A first detection mechanism includes a picking component and a detection component, wherein the picking component is used to pick up the material on the first conveyor line and place the material on the first detection station, and the detection component is used to perform conductivity detection on the material on the first detection station; a second conveyor line, passing through the grinding station and the second inspection station in sequence, the second conveyor line having a raised position and a lowered position; in the raised position, the second conveyor line is higher than the grinding station and the second inspection station to transport the material; in the lowered position, the second conveyor line is lower than the grinding station and the second inspection station to place the material on the grinding station and / or the second inspection station; a grinding mechanism disposed on the frame and having a first position and a second position; wherein, in the first position, the grinding mechanism is close to the grinding station and grinds the material on the grinding station; and in the second position, the grinding mechanism is away from the grinding station; The second detection mechanism includes a sensor system, and the sensor system is used to identify image information and / or three-dimensional information of the material placed on the second detection station.

[0005] Compared with the existing technology, the above technical scheme has the following beneficial technical effects: the first detection mechanism can automatically detect the conductivity of the material, the grinding mechanism can automatically grind the material, and the second detection mechanism can automatically detect the smoothness of the grinding part of the material. At the same time, the conveying paths of the first conveyor line and the second conveyor line can realize the automatic conveying of the material in the first detection mechanism, the grinding mechanism, and the second detection mechanism. Therefore, through the above technical scheme, the two subsequent processes of the conductive performance detection of the armature and the surface grinding of the armature commutator can be fully automated, thereby improving the production efficiency of the armature.

DETAILED DESCRIPTION

[0025] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0026] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0027] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring the embodiments of the present invention.

[0028] To realize the automatic control of the present invention, the armature commutator back-end production line provided by the present invention includes a control system 200, see Figure 1 The control system 200 includes a processor 201 and a memory 202 in communication with the processor 201. The memory 202 and the processor 201 may be connected via a bus 203. The memory 202 is used to store computer programs, and the processor 201 is used to execute the computer programs stored in the memory 202 to cause the various electronic components on the armature commutator downstream production line to operate according to pre-edited programs and logic. The operation of the processor 201, memory 202, computer programs, and related logic is the same as in the prior art and will not be further described here.

[0029] See Figure 2The armature commutator production line also includes a frame 300, constructed from metal profiles (such as aluminum). This frame is used to support and mount the components that make up the armature commutator production line. The frame 300 can be placed directly on the ground, secured to the ground by its own gravity, or secured to the ground with anchor bolts.

[0030] See Figure 3 Multiple conveyor lines are provided on the frame 300, which are used to automatically transport the material (the armature to be processed). A first inspection station 301, a grinding station 302, and a second inspection station 303 are fixedly connected to the frame 300 in sequence along the material's conveying direction. During transportation, the material is sequentially placed on the first inspection station 301, the grinding station 302, and the second inspection station 303. Different processing steps are performed on the material at different stations. For example, the material's conductivity (such as the conductivity between the commutator and windings of the armature) is tested at the first inspection station 301, the material is ground at the grinding station 302, and the smoothness of the ground portion of the material is tested at the second inspection station 303.

[0031] See Figure 4 and Figure 5 Exemplarily, the first inspection station 301 includes a first support seat 3011, a first rotating roller 3012, and a first motor 3013. The first support seat 3011 is fixedly connected to the frame 300, and the first rotating roller 3012 includes a connecting end connected to the first support seat 3011 and a free end away from the first support seat 3011, wherein the connecting end passes through the first support seat 3011 and is rotatably connected to the first support seat 3011 through a bearing. The free end extends in a direction away from the first support seat 3011 and is suspended. Two first rotating rollers 3012 are arranged side by side in the horizontal direction, and the material can be supported between the upper surfaces of the two first rotating rollers 3012. The first motor 3013 can be fixedly connected to the frame 300, or fixedly connected to the first support seat 3011. A driving pulley is coaxially fixed to the output end of the first motor 3013. Driven pulleys are respectively fixed to the ends of the two first rotating rollers 3012 that pass through the connection end of the first support seat 3011. A synchronous belt 403 is wound around the driving pulley and the two driven pulleys. When material is placed between the two first rotating rollers 3012 and becomes skewed, the first motor 3013 can be started. The first motor 3013 drives the two driven pulleys to rotate via the driving pulley. The two driven pulleys then drive the two first rotating rollers 3012 to rotate in the same direction, causing the material to rotate in parallel with the two first rotating rollers 3012. During the material rotation process, the material's position can be adjusted so that the material's axis is parallel to the axis of the first rotating rollers 3012.

[0032] See Figure 4 and Figure 5 Furthermore, to detect whether the material is flush on the two first rotating rollers 3012, a sensing system 3014 is provided on the first support base 3011. The sensing system 3014 is a laser sensor, a camera, or a combination of at least two. Exemplarily, the sensing system 3014 is a laser sensor, with the transmitting end of the laser sensor facing the material placement area of ​​the two first rotating rollers 3012. When the material is placed on the two first rotating rollers 3012, the laser sensor emits a laser beam toward the material. The laser beam reflects off the material surface and is then received by the laser sensor. The laser sensor then analyzes the received reflected laser light to obtain the material's current coordinate information. Reference coordinates are pre-stored in the memory 202 of the armature commutator downstream production line. Current coordinate information is compared with the reference coordinate information to determine whether the material is aligned flush on the two first rotating rollers 3012. If the current coordinate information is identical to the reference coordinate information or is within the error range, the material is aligned flush on the two first rotating rollers 3012. Otherwise, the material is not aligned flush on the two first rotating rollers 3012. If the material is not aligned flush on the two first rotating rollers 3012, the control system 200 activates the first motor 3013 to adjust the material's position. In other examples, the sensing system 3014 is a camera, with the camera's image capture end facing the area on the two first rotating rollers 3012 where the material is placed. When the material is placed on the two first rotating rollers 3012, the camera captures current image information of the material. A reference image is pre-stored in the memory 202 of the armature commutator downstream production line. The current image information is compared with the reference image to determine whether the material is flush on the two first rotating rollers 3012. If the current image information is the same as the reference image or the deviation is within the error range, it means that the material is flush on the two first rotating rollers 3012. Otherwise, it means that the material is not flush on the two first rotating rollers 3012. When the material is not flush on the two first rotating rollers 3012, the control system 200 controls the first motor 3013 to start in order to adjust the posture of the material. It should be noted that the above-mentioned camera includes but is not limited to a monocular camera, a multi-camera camera, a fisheye camera, a CCD sensor, a high-definition camera, etc. As long as the camera can realize image acquisition and cooperate with the control system 200 to generate image information, this application does not limit the specific type of camera.

[0033] See Figure 3 and Figure 6The grinding station 302 includes two opposing second support blocks 3021, each fixedly connected to the frame 300. Bearing bearings 3022 are rotatably connected to the opposing end surfaces of the two second support blocks 3021. Two bearing bearings 3022 are paired on the end surface of each second support block 3021. One end of the material is supported between the upper surfaces of the two bearing bearings 3022 of one second support block 3021, while the other end of the material is supported between the upper surfaces of the two bearing bearings 3022 of the other second support block 3021. The bearing bearings 3022 on the end surfaces of the second support blocks 3021 ensure smooth rotation of the material on the second support blocks 3021.

[0034] The second inspection station 303 has the same structure as the grinding station 302 , and the only difference is the fixed position on the frame 300 . The structure of the second inspection station 303 refers to the grinding station 302 and will not be repeated here.

[0035] See Figure 7 The armature commutator back-end production line also includes a first conveyor line 400. The first conveyor line 400 is a synchronous belt 403 conveyor line. The synchronous belt 403 conveyor line includes a bracket 401 and a second motor 402. One end of the bracket 401 in the length direction is rotatably connected to a driving pulley, and the other end is rotatably connected to a driven pulley. A synchronous belt 403 is wound around the driving pulley and the driven pulley. The second motor 402 is fixedly connected to one end of the bracket 401 close to the driving pulley. The output end of the second motor 402 is coaxially fixed with the driving pulley and is used to drive the driving pulley to rotate, thereby driving the synchronous belt 403 to move. When transporting materials, the materials are placed on the synchronous belt 403, and the transportation of the materials is achieved through the movement of the synchronous belt 403. One end of the first conveyor line 400 is set close to the first inspection station 301. In this way, the materials can be transported to a position close to the first inspection station 301 through the first conveyor line 400.

[0036] See Figure 2 、 Figures 8-10 The armature commutator downstream production line also includes a first detection mechanism 500, which includes a picking component 501 and a detection component 502. The picking component 501 is used to pick up the material on the first conveyor line 400 and place the material on the first detection station 301. The detection component 502 is used to perform conductivity detection on the material on the first detection station 301.

[0037] See Figure 8In one embodiment, the picking component 501 includes a third conveyor line 5011 and a first grabbing arm 5012. The third conveyor line 5011 is a synchronous belt 403 conveyor line. The third conveyor line 5011 has the same structure as the first conveyor line 400. The difference between the two is only the setting position and the transportation direction, which will not be described here. The first grabbing arm 5012 is connected to the third conveyor line 5011. Specifically, the first grabbing arm 5012 is connected to the synchronous belt 403 of the third conveyor line 5011. The third conveyor line 5011 can drive the first grabbing arm 5012 to move between the first conveyor line 400 and the first inspection station 301, so as to use the first grabbing arm 5012 to transport the material from the first conveyor line 400 to the first inspection station 301.

[0038] See Figure 8 In one embodiment, the first grabbing arm 5012 includes a first driving member 5013 and a magnetic base 5014. The first driving member 5013 is connected to the third conveyor line 5011. Specifically, a first mounting base 503 is fixedly connected to the synchronous belt 403 of the third conveyor line 5011, and the first driving member 5013 is fixedly connected to the first mounting base 503. The first driving member 5013 is connected to the synchronous belt 403 of the third conveyor line 5011 through the first mounting base 503. In other examples, the first driving member 5013 can also be fixedly connected to the synchronous belt 403 of the third conveyor line 5011. As long as the second driving member 50181 and the synchronous belt 403 of the third conveyor line 5011 can be relatively fixed, this application does not limit the fixing method between the first driving member 5013 and the synchronous belt 403 of the third conveyor line 5011.

[0039] See Figure 8In the embodiment of the present application, a first driving member 5013 is connected to the synchronous belt 403 of the third conveyor line 5011 via a first mounting base 503 as an example. The third conveyor line 5011 can drive the first mounting base 503 to drive the first driving member 5013 to move between the first conveyor line 400 and the first inspection station 301. The first driving member 5013 is a pneumatic cylinder or an oil cylinder. The output end of the first driving member 5013 can move in the height direction. A first extension plate 5015 is fixedly connected to the output end of the first driving member 5013. A magnetic base 5014 is fixedly connected to the first extension plate 5015. The magnetic base 5014 is connected to the output end of the first driving member 5013 via the first extension plate 5015. A first electromagnet 5016 is provided on the magnetic base 5014. The first electromagnet 5016 is electrically connected to the control system 200. The control system 200 can control the on and off of the first electromagnet 5016. When the first electromagnet 5016 is powered on, the first electromagnet 5016 can absorb materials through magnetic force to pick up the materials from the first conveyor line 400 to the first inspection station 301; when the first electromagnet 5016 is powered off, the first electromagnet 5016 no longer has magnetic force and cannot absorb materials.

[0040] When the material on the first conveyor line 400 needs to be transferred to the first inspection station 301, the first grabbing arm 5012 first moves to the top of the first conveyor line 400 through the third conveyor line 5011. When the magnetic seat 5014 is just above the material, the first driving member 5013 drives the first electromagnet 5016 of the magnetic seat 5014 to descend to fit with the surface of the material. At the same time, the first electromagnet 5016 is energized to generate magnetic force, and the material is sucked by the magnetic force. Next, while keeping the first electromagnet 5016 energized, the first driving member 5013 drives the magnetic seat 5014 to rise to the highest position, and then the first grabbing arm 5012 carries the picked up material and moves to the top of the first inspection station 301 through the third conveyor line 5011. When the magnetic seat 5014 is just above the first inspection station 301, the first driving member 5013 drives the magnetic seat 5014 to descend until the material descends to between the upper surfaces of the two first rotating rollers 3012. Then, the first electromagnet 5016 is de-energized to release the suction of the material, and the first driving member 5013 is used to drive the magnetic seat 5014 to rise to leave the material between the upper surfaces of the two first rotating rollers 3012.

[0041] It should be noted that the third conveyor line 5011 has a first stop point and a second stop point along its conveying direction. The first stop point is located directly above the position on the first conveyor line 400 where the first grabbing arm 5012 grabs materials, and the second stop point is located directly above the first inspection station 301. When the third conveyor line 5011 drives the first grabbing arm 5012 to move to the first stop point, the magnetic seat 5014 is located directly above the position on the first conveyor line 400 where the first grabbing arm 5012 grabs materials; when the third conveyor line 5011 drives the first grabbing arm 5012 to move to the second stop point, the magnetic seat 5014 is located directly above the first inspection station 301. Figure 7 A photoelectric sensor 5017 is provided at the position on the first conveyor line 400 where the first grabbing arm 5012 grabs the material. When the material moves to the photoelectric sensor 5017, the photoelectric sensor 5017 can sense the material and transmit the signal to the control system 200. The control system 200 executes the above-mentioned process of transferring the material on the first conveyor line 400 to the first detection station 301.

[0042] See Figure 9 and Figure 10After the material is between the two first rotating rollers 3012 and its position is adjusted, the detection component 502 detects the conductive properties of the material. In one embodiment, the detection component 502 is arranged near the first detection station 301, and the detection component 502 includes a chuck seat 5021 and a clamping claw 5022. The chuck seat 5021 is arranged on the frame 300, and a plurality of movable grooves 5023 are provided on the chuck seat 5021 along the circumference. The extension lines of the length direction of each movable groove 5023 are focused on one point, and the focusing point is the center of the circle formed by the circumferential distribution of each movable groove 5023. There is one clamping claw 5022 in each movable groove 5023, that is, there are multiple clamping claws 5022 on the chuck along the circumference. One end of the claw 5022 is located within the movable groove 5023. The claw 5022 is smaller than the movable groove 5023 in the longitudinal direction thereof, thereby enabling the claw 5022 to move along the longitudinal direction of the movable groove 5023. The end of the claw 5022 away from the movable groove 5023 is an extension end, which extends toward the first inspection station 301. A retractable tray 5024 is provided on the side of the chuck base 5021 facing away from the first inspection station 301. The retractable tray 5024 is rotatably connected to the chuck base 5021, and the rotation center of the retractable tray 5024 is coaxial with the center of a circle formed by the circumferential distribution of the movable grooves 5023. A plurality of receiving and releasing grooves 5025 are provided along the circumference of the receiving and releasing disk 5024. The receiving and releasing grooves 5025 correspond one-to-one with the movable grooves 5023. The length of the receiving and releasing grooves 5025 and the length of the movable grooves 5023 are arranged at an angle b. Specifically, the length of the line connecting one end of the receiving and releasing groove 5025 and the rotation center of the receiving and releasing disk 5024 is greater than the line connecting the other end of the receiving and releasing groove 5025 and the rotation center of the receiving and releasing disk 5024. Furthermore, the line connecting one end of the receiving and releasing groove 5025 and the rotation center of the receiving and releasing disk 5024 and the line connecting the other end of the receiving and releasing groove 5025 and the rotation center of the receiving and releasing disk 5024 form an angle a, which represents the rotatable angle of the receiving and releasing disk 5024. The angle b is set according to actual needs, as long as the receiving and releasing grooves 5025 and the movable groove 5023 always have a through receiving and releasing hole 50251 when the receiving and releasing disk 5024 rotates within the range of the angle a. An extension rod 5026 is fixed on the end surface of the clamping claw 5022 away from the extension end. The extension rod 5026 passes through a retracting hole 50251 formed by the superposition of the retracting groove 5025 and the moving groove 5023.

[0043] See Figure 9 and Figure 10A rotary drive member 5027 is fixedly connected to the chuck seat 5021. The rotary drive member 5027 can be a rotary cylinder or a motor. The output end of the rotary drive member 5027 is coaxially fixed to the rotation center of the receiving and releasing disk 5024. In this way, the receiving and releasing disk 5024 can be driven to rotate within the range of the angle a by the rotary drive member 5027. A detection probe 5028 is respectively provided on the extended end of each clamping claw 5022. Specifically, a mounting hole is penetrated in the extended end. The penetration direction of the mounting hole is consistent with the longitudinal direction of the movable groove 5023. The detection probe 5028 is inserted into the mounting hole and has an interference fit. The detection end of the detection probe 5028 is located on the inner side of the clamping claw 5022.

[0044] Through the cooperation of the above-mentioned rotating driving member 5027, the receiving and releasing groove 5025 and the movable groove 5023, multiple claws 5022 have a retracted state and a dispersed state on the chuck. Specifically, when it is necessary to test the conductive properties of the material, the rotating driving member 5027 drives the receiving and releasing disk 5024 to rotate in a first direction, so as to cause the receiving and releasing hole 50251 formed by the receiving and releasing groove 5025 and the movable groove 5023 to gradually approach the rotation center of the receiving and releasing disk 5024. This gradual approaching trend causes each claw 5022 to move along the length direction of the movable groove 5023, so that each claw 5022 gradually retracts toward the rotation center of the receiving and releasing disk 5024, so that the detection end of the detection probe 5028 on each claw 5022 respectively contacts the part to be detected of the material, and then the detection probe 5028 is started to perform conductivity detection on the material. After completing the conductivity test of the material, the rotary drive member 5027 drives the receiving and releasing disk 5024 to rotate in a second direction, causing the receiving and releasing hole 50251 formed by the receiving and releasing groove 5025 and the movable groove 5023 to gradually move further away from the rotation center of the receiving and releasing disk 5024. This gradual movement away causes each claw 5022 to move along the length of the movable groove 5023, causing each claw 5022 to gradually disperse relative to the rotation center of the receiving and releasing disk 5024, thereby causing the detection end of the detection probe 5028 on each claw 5022 to gradually move away from the detection position of the material, thereby placing the multiple detection probes 5028 in a non-detection state. It should be noted that the first and second directions are opposite rotational directions. At the same time, using the detection probes 5028 to detect the conductivity of the material is a prior art and will not be described in detail here.

[0045] See Figure 9 and Figure 10In one embodiment, the detection assembly 502 further includes a driving source 5029, which is fixedly connected to the frame 300. The output end of the driving source 5029 is movable toward and away from the first detection station 301. The chuck base 5021 is slidably connected to the frame 300 and connected to the output end of the driving source 5029. When the conductivity test of the material is required, the driving source 5029 drives the chuck base 5021 to move toward the first detection station 301. When the conductivity test of the material is completed, the driving source 5029 drives the chuck base 5021 to move away from the first detection station 301.

[0046] See Figure 9 and Figure 10 A guide rail pair is provided on the bottom surface of the chuck base 5021, and the guide rail pair includes a guide rail and a sliding seat. The sliding seat is fixedly connected to the bottom surface of the chuck base 5021, and the guide rail is fixedly connected to the frame 300, and the length direction of the guide rail (i.e., the guiding direction of the guide rail) points to the first detection station 301. By setting the guide rail pair, the stability of the chuck base 5021 when moving toward and away from the first detection station 301 is improved. In other examples, the sliding seat can also be fixedly connected to the frame 300, and correspondingly, the guide rail is fixedly connected to the bottom surface of the chuck base 5021. The number of guide rail pairs can be one group or no less than two groups. The number of guide rail pairs is not limited, as long as the stable sliding of the chuck base 5021 can be achieved.

[0047] See Figure 9 and Figure 10 The driving source 5029 can be a pneumatic cylinder or an oil cylinder. In this case, the driving source 5029 is fixedly connected to the frame 300, and the output end of the driving source 5029 can move in the direction toward and away from the first detection station 301. The chuck seat 5021 is connected to the output end of the driving source 5029. In this way, the chuck seat 5021 can be driven close to and away from the first detection station 301 by the driving source 5029. In other examples, the driving source 5029 can also be a combination of a motor and a screw assembly. In this case, the screw assembly includes a guide screw and a nut seat. The motor is fixedly connected to the frame 300, and the axial direction of the output shaft of the motor is straight to the first detection station 301. The guide screw is coaxially connected to the output shaft of the motor. The nut seat is fixedly connected to the bottom surface of the chuck seat 5021. The nut seat is sleeved on the guide screw and cooperates with the guide screw thread. The nut seat is equivalent to the output end of the driving source 5029. Under the threaded feed of the guide screw, the nut seat can move in the direction toward and away from the first detection station 301. After this arrangement, the chuck seat 5021 can be driven close to and away from the first detection station 301 through the cooperation of the motor and the screw assembly.

[0048] After the material is picked up by the first grabbing arm 5012 and brought to the first inspection station 301, and the two first rotating rollers 3012 adjust the material's position, the drive source 5029 drives the chuck base 5021 toward the first inspection station 301, so that the extended ends of the claws 5022 on the chuck base 5021 surround the portion of the material to be inspected. Next, the rotary drive member 5027 drives the claws 5022 to a retracted position, allowing the material to be tested for conductivity using the detection probe 5028. After the conductivity test is completed, the rotary drive member 5027 drives the claws 5022 to a dispersed position, and then the drive source 5029 drives the chuck base 5021 in a direction away from the first inspection station 301 until the chuck base 5021, carrying the claws 5022, is completely away from the material.

[0049] In one embodiment, to improve the efficiency of conductivity testing, two first testing stations 301 are arranged side by side on the frame 300 along the conveying direction of the third conveyor line 5011. Two detection assemblies 502 are also arranged side by side on the frame 300 along the conveying direction of the third conveyor line 5011. The detection assemblies 502 correspond one to one with the first testing stations 301. Accordingly, two second stop points are also provided on the third conveyor line 5011. With this arrangement, the two first testing stations 301 and the two detection assemblies 502 can each perform conductivity testing, greatly improving the efficiency of conductivity testing.

[0050] See Figure 3 and Figure 11 The armature commutator back-end production line also includes a second conveyor line 600, which sequentially passes through the grinding station 302 and the second inspection station 303. The second conveyor line 600 has a raised position and a lowered position. In the raised position, the second conveyor line 600 is above the grinding station 302 and the second inspection station 303 to transport materials. In the lowered position, the second conveyor line 600 is below the grinding station 302 and the second inspection station 303 to place materials on the grinding station 302 and / or the second inspection station 303.

[0051] See Figure 11 Exemplarily, the second conveyor line 600 includes a transport rod 601, a lifting member 602, and a telescopic member 603. The transport rod 601 is an elongated rod, one end of which is close to the first inspection station 301 and the other end extends in the horizontal direction, and passes through at least the grinding station 302 and the second inspection station 303 in sequence. The transport rod 601 is simultaneously located between the two second support seats 3021 of the grinding station 302 and between the two second support seats 3021 of the second inspection station 303. The transport rod 601 can be extended and retracted in the horizontal direction between the two second support seats 3021 of the grinding station 302 and the two second support seats 3021 of the second inspection station 303, and can also be raised and lowered in the height direction.

[0052] See Figure 11 The transport rod 601 is slidably coupled to a guide seat 604. The guide seat 604 is located on the bottom surface of the transport rod 601, and the guide seat 604 and the transport rod 601 form a guide rail pair. The lifting member 602 is a pneumatic cylinder or an oil cylinder. The body of the lifting member 602 is fixedly connected to the frame 300. The telescopic end of the lifting member 602 can be raised and lowered in the height direction. The guide seat 604 is fixedly connected to the telescopic end of the lifting member 602. In this way, the lifting member 602 is used to lift and lower the guide seat 604 in the height direction, so that the transport rod 601 can be lifted and lowered in the height direction between the two second support seats 3021 of the grinding station 302 and the two second support seats 3021 of the second inspection station 303. In addition, to improve the stability of the transport rod 601 in the transport direction and the stability of the transport rod 601 in the height direction, multiple guide seats 604 are provided along the transport direction of the transport rod 601, and multiple lifting members 602 are also provided along the transport direction of the transport rod 601, with multiple guide seats 604 and multiple lifting members 602 corresponding one to one. The telescopic member 603 is a pneumatic cylinder or an oil cylinder, and the telescopic end of the telescopic member 603 is telescopic in the same direction as the transport direction of the transport rod 601. The end of the telescopic member 603 away from the telescopic end is fixedly connected to any of the above-mentioned guide seats 604. The telescopic end of the telescopic member 603 is fixedly connected to a connecting plate 605, and the end of the connecting plate 605 away from the telescopic end of the telescopic cylinder is fixedly connected to the transport rod 601. In this way, the telescopic member 603 enables the transport rod 601 to be telescopically extended and retracted in the horizontal direction between the two second support seats 3021 of the grinding station 302 and the two second support seats 3021 of the second inspection station 303. A temporary work station 606 is fixedly connected to the top surface of the transport rod 601. Multiple temporary work stations 606 are provided along the length direction of the transport rod 601. The temporary work station 606 includes a third support seat 6061. The third support seat 6061 is fixedly connected to the transport rod 601. A material slot 6062 for placing materials is provided on the side of the third support seat 6061 facing away from the transport rod 601.

[0053] See Figure 3 and Figure 8 In one embodiment, the picking component 501 also includes a second grabbing arm 5018, and the second grabbing arm 5018 is connected to the third conveyor line 5011. Specifically, the second grabbing arm 5018 is connected to the synchronous belt 403 of the third conveyor line 5011. The third conveyor line 5011 can drive the second grabbing arm 5018 to move between the first inspection station 301 and the second conveyor line 600, so as to use the second grabbing arm 5018 to transport the material from the first inspection station 301 to the second conveyor line 600.

[0054] See Figure 8In one embodiment, the second grabbing arm 5018 includes a second driving member 50181 and a manipulator 50182. The second driving member 50181 is connected to the third conveyor line 5011. Specifically, the second driving member 50181 can be fixedly connected to the first mounting base 503, or fixedly connected to the synchronous belt 403 of the third conveyor line 5011. A second mounting base can also be fixedly connected to the synchronous belt 403 of the third conveyor line 5011, and the second driving member 50181 is fixedly connected to the second mounting base. As long as the second driving member 50181 and the synchronous belt 403 of the third conveyor line 5011 can be relatively fixed, this application does not limit the fixing method between the first driving member 5013 and the synchronous belt 403 of the third conveyor line 5011.

[0055] See Figure 8 In the embodiment of the present application, the second driving member 50181 is connected to the synchronous belt 403 of the third conveyor line 5011 through the first mounting base 503 as an example for explanation. The third conveyor line 5011 can drive the second driving member 50181 to move between the first inspection station 301 and the second conveyor line 600 by driving the first mounting base 503. The second driving member 50181 is a pneumatic cylinder or an oil cylinder. The output end of the second driving member 50181 can move in the height direction. A third extension plate 50183 is fixedly connected to the output end of the second driving member 50181. The manipulator 50182 is fixedly connected to the third extension plate 50183. The manipulator 50182 is connected to the output end of the second driving member 50181 through the third extension plate 50183. The manipulator 50182 is used to pick up materials from the first inspection station 301 to the second conveyor line 600. The manipulator 50182 is electrically connected to the control system 200. It should be noted that the manipulator 50182 is a conventional structure in this field and will not be described in detail in this application.

[0056] See Figure 3 and Figure 8Along the conveying direction of the third conveyor line 5011, the second grabbing arm 5018 is closer to the second conveyor line 600 than the first grabbing arm 5012. The third conveyor line 5011 also has a third stop point along its conveying direction, and the third stop point is located directly above the second conveyor line 600. The relative positions of the first grabbing arm 5012 and the second grabbing arm 5018 are pre-set to meet the following conditions: when the first grabbing arm 5012 is located directly above the position of the first conveyor line 400 for the first grabbing arm 5012 to grab materials, the second grabbing arm 5018 is located directly above the first inspection station 301 close to the first conveyor line 400; when the first grabbing arm 5012 is located directly above the first inspection station 301 close to the first conveyor line 400, the second grabbing arm 5018 is located directly above the first inspection station 301 close to the second conveyor line 600; when the first grabbing arm 5012 is located directly above the first inspection station 301 close to the second conveyor line 600, the second grabbing arm 5018 is located directly above the second conveyor line 600. This arrangement can improve the efficiency of material transfer between the first conveyor line 400, the first inspection station 301 and the second conveyor line.

[0057] See Figure 3 and Figure 8 In one embodiment, a placement station 607 is provided at the starting end of the second conveyor line 600. The placement station 607 is fixedly connected to the frame 300, and the manipulator 50182 is used to pick up materials from the first inspection station 301 to the placement station 607. The third stop point is located directly above the placement station 607. The placement station 607 is a station for temporarily placing materials, and is used to temporarily place materials from the first inspection station 301. When the first grabbing arm 5012 is located directly above the first inspection station 301 close to the second conveyor line 600, the second grabbing arm 5018 is located directly above the second conveyor line 600, and the manipulator 50182 of the second grabbing arm 5018 is located directly above the placement station 607. It should be noted that the structures of the placement station 607 and the grinding station 302 are the same, and the only difference is the setting position, which will not be repeated here.

[0058] In this way, after the material is inspected at the first inspection station 301, the second grabbing arm 5018 is used to grab the material, and then the third conveyor line 5011 is used to move the second grabbing arm 5018 to directly above the second conveyor line 600 until the manipulator 50182 is directly above the placement station 607. Then, the second grabbing arm 5018 lowers the material to the placement station 607. It should be noted that the action process of the second grabbing arm 5018 grabbing the material from the first inspection station 301 to the placement station 607 is roughly the same as the action process of the first grabbing arm 5012 grabbing the material from the first conveyor line 400 to the first inspection station 301. The only difference is the material grabbing position, the material lowering position, and the material grabbing method. This application will not elaborate on this in detail.

[0059] Multiple groups of placement stations 607 can be set at the starting end of the second conveyor line 600. If only one group of placement stations 607 is set, then when there is already material at the placement station 607, the material located at the first detection station 301 needs to wait until the placement station 607 becomes an empty position before it can be moved to the first placement position, which seriously affects the efficiency of the conductivity detection. After multiple groups of placement stations 607 can be set at the starting end of the second conveyor line 600, the number of placement stations 607 is sufficient. After the material completes the conductivity test, the second grabbing arm 5018 can immediately transfer the material to the placement station 607, reducing the material's residence time at the first detection station 301, thereby improving the work continuity of the entire production line of this application and further improving efficiency.

[0060] After the material is transferred to the placement station 607, the material waits for transportation by the second conveyor line 600, so as to enter the grinding station 302 for grinding processing and enter the second inspection station 303 for other inspections. The process of transporting the material from the placement station 607 to the grinding station 302 is as follows: when the lifting member 602 maintains the transport rod 601 in a lowered state, the telescopic member 603 pushes the end of the transport rod 601 near the starting section of the second conveyor line 600 to the starting section of the second conveyor line 600, and then the lifting member 602 drives the transport rod 601 to rise until the transport rod 601 is higher than the placement station 607, the grinding station 302 and the second inspection station 303. During this process, the temporary station 606 on the transport rod 601 lifts the material on the placement station 607, and the temporary station 606 uses its material clamping slot 6062 to confine the material on the temporary station 606. Then, while the transport rod 601 remains in an ascending state, the telescopic part 603 drives the transport rod 601 to carry the material to the grinding station 302. When the material is just above the grinding station 302, the lifting part 602 drives the transport rod 601 to descend. When the transport rod 601 descends to below the placement station 607, the grinding station 302 and the second inspection station 303, the material is restricted by the grinding station 302 and detached from the temporary station 606. The two ends of the material are respectively overlapped on the two second support seats 3021 of the grinding station 302, thereby realizing the transportation of the material from the placement station 607 to the grinding station 302. It should be noted that the process of transporting the material from the grinding station 302 to the second inspection station 303 is the same as the process of transporting the material from the placement station 607 to the grinding station 302. Both of them first lift the material from the original station through the transport rod 601, and then use the transport rod 601 to transport it to the designated station, and then lower the transport rod 601 to leave the material at the designated station. This application will no longer elaborate on the detailed process of transporting the material from the grinding station 302 to the second inspection station 303.

[0061] See Figure 2 、 Figure 12 and Figure 13 In one embodiment, the armature commutator back-end production line further includes a grinding mechanism 700 , which is mounted on the frame 300 and has a first position and a second position. In the first position, the grinding mechanism 700 is close to the grinding station 302 and grinds the material thereon. In the second position, the grinding mechanism 700 is away from the grinding station 302 .

[0062] See Figure 12 and Figure 13In one embodiment, the grinding mechanism 700 includes a grinding assembly 701, a first drive assembly 702, and a first feed assembly 703. The grinding assembly 701 includes a grinding mount 7011 and a grinding tool 7012. The grinding tool 7012 is detachably connected to the grinding mount 7011. The grinding mount 7011 is connected to the first feed assembly 703. The first feed assembly 703 is used to drive the grinding mount 7011 to move between a first position and a second position. The first drive assembly 702 is located above the grinding station 302. When the grinding mount 7011 is in the first position, the grinding tool 7012 contacts the surface of the material to be ground. The first drive assembly 702 is used to drive the material located on the grinding station 302 to rotate, thereby grinding the material using the grinding tool 7012.

[0063] See Figure 12 and Figure 13 , exemplarily, the grinding mounting seat 7011 includes a seat body 7013, to which a tool mounting seat 7014 is fixedly connected. The tool mounting seat 7014 is provided with a mounting groove 7015 on a side facing the grinding station 302. The non-grinding end of the grinding tool 7012 is provided in the mounting groove 7015. The connection between the grinding tool 7012 and the mounting groove 7015 is a detachable connection method, for example, fixed by bolts. Specifically, a threaded hole communicating with the mounting groove 7015 is provided on the tool mounting seat 7014. The bolt is threadedly connected to the threaded hole and passes through the threaded hole, so that the grinding tool 7012 is tightened in the mounting groove 7015 by the bolt. When disassembling, it is only necessary to unscrew the bolt to disassemble the grinding tool 7012. The connection method between the grinding tool 7012 and the mounting groove 7015 can also be a snap connection, an interference fit, a threaded connection, etc., which is not limited in this application, as long as a detachable connection between the grinding tool 7012 and the mounting groove 7015 can be achieved. This arrangement facilitates the maintenance or replacement of the grinding tool 7012 and improves the reuse rate.

[0064] See Figure 12 and Figure 13The first feed assembly 703 is disposed between the base 7013 and the frame 300 and includes a third motor 7031, a first feed screw 7032, and a first screw seat 7033. The third motor 7031 is fixedly connected to the frame 300, and the first feed screw 7032 is coaxially fixed to the output shaft of the third motor 7031. The axial direction of the first feed screw 7032 points toward the grinding station 302. The first screw seat 7033 is fixedly connected to the bottom of the base 7013. The first screw seat 7033 is sleeved on the first feed screw 7032 and is threadedly engaged with the first feed screw 7032. The third motor 7031 can drive the first feed screw 7032 to rotate. The threaded engagement between the first feed screw 7032 and the first screw seat 7033 can cause the first screw seat 7033 to move axially along the first feed screw 7032, thereby causing the first screw seat 7033 to drive the grinding mount 7011 to move toward and away from the grinding station 302. In this way, the first feed assembly 703 can drive the grinding mount 7011 to move toward and away from the grinding station 302. When the seat 7013 is close to the grinding station 302 and the grinding tool 7012 contacts the surface of the material to be ground, the position of the grinding mount 7011 is the first position. Except for this position, the position of the grinding mount 7011 can be the second position. In other examples, the first feed assembly 703 can also be a pneumatic cylinder or an oil cylinder, which directly drives the grinding mount 7011 to move. In addition, in order to improve the movement stability of the grinding mounting seat 7011, a guide rail pair is provided between the seat body 7013 and the frame 300. The present application does not limit the number of guide rail pairs, as long as the stable movement of the second seat body 7017 can be achieved.

[0065] See Figure 12 and Figure 13In one embodiment, the base 7013 may include a first base 7016 and a second base 7017, wherein the first base 7016 is located below the second base 7017. The first feed assembly 703 is disposed between the first base 7016 and the frame 300, and the tool mounting base 7014 is fixedly connected to the second base 7017. The grinding mechanism 700 may further include a second feed assembly 704, which is disposed between the first base 7016 and the second base 7017. The second feed assembly 704 includes a fourth motor 7041, a second feed screw 7042, and a second screw seat 7043. The fourth motor 7041 is fixedly connected to the first base 7016, and the second feed screw 7042 is coaxially fixed to the output shaft of the fourth motor 7041. The axial direction of the second feed screw 7042 is perpendicular to the axial direction of the first feed screw 7032. The second screw seat 7043 is fixedly connected to the bottom of the second base body 7017. The second screw seat 7043 is sleeved on the second feed screw 7042 and is threadedly engaged with the second feed screw 7042. The fourth motor 7041 can drive the second feed screw 7042 to rotate. The threaded engagement between the second feed screw 7042 and the second screw seat 7043 can cause the second screw seat 7043 to move along the axial direction of the second feed screw 7042, thereby causing the second screw seat 7043 to drive the second base body 7017 to move in a direction perpendicular to the axis of the first feed screw 7032. With this arrangement, before the first feed assembly 703 drives the grinding mount 7011 toward the grinding station 302, the second feed assembly 704 first drives the second base 7017 to move a certain distance away from the grinding station 302, so that the grinding tool 7012 is away from the grinding station 302. Then, the first feed assembly 703 drives the grinding mount 7011 toward the grinding station 302. After the grinding mount 7011 approaches the grinding station 302, the second feed assembly 704 drives the second base 7017 to move a certain distance toward the grinding station 302, so that the grinding tool 7012 approaches the grinding station 302 and contacts the portion of the material to be ground (e.g., the surface of the armature commutator). With this arrangement, the possibility of the grinding tool 7012 directly feeding the grinding tool 7012 to the material is avoided, thereby protecting both the grinding tool 7012 and the material. In other examples, the second feeding assembly 704 may also be a pneumatic cylinder or an oil cylinder, which directly drives the movement of the second base 7017. In addition, to improve the movement stability of the second base 7017, a guide rail pair is provided between the first base 7016 and the second base 7017. The present application does not limit the number of guide rail pairs, as long as they can achieve stable movement of the second base 7017.

[0066] See Figure 12 and Figure 13In one embodiment, the first drive assembly 702 includes a third drive member 7021, a first mounting seat 7022, a first pulley set 7023, a first synchronous belt 7024, and a fourth drive member 7025. The third drive member 7021 is fixedly connected to the first mounting seat 7022. The first pulley set 7023 includes a plurality of pulleys, each of which is rotatably connected to the first mounting seat 7022. The first synchronous belt 7024 is wound around the plurality of pulleys of the first pulley set 7023. The third drive member 7021 is a motor. The output shaft of the third drive member 7021 is coaxially fixed to any pulley in the first pulley set 7023. The third drive member 7021 can drive the first pulley set 7023 to rotate, thereby driving the first synchronous belt 7024 to perform a rotary motion outside the first pulley set 7023. The fourth drive member 7025 is fixedly connected to the frame 300. The fourth drive member 7025 is a pneumatic or hydraulic cylinder, and its output end is movable in the vertical direction. The first mounting seat 7022 is fixedly connected to the output end of the fourth drive member 7025. The first mounting seat 7022 is located above the grinding station 302. When the output end of the fourth drive member 7025 moves to the lowest position, the first mounting seat 7022 drives the first synchronous belt 7024 to press the material on the grinding station 302. During the rotation of the first synchronous belt 7024, friction causes the material to rotate. As the material rotates, the grinding tool 7012 grinds the material.

[0067] See Figure 14In other embodiments, the grinding mechanism 700 includes a grinding assembly 701 and a first drive assembly 702. The first drive assembly 702 is consistent with the first drive assembly 702 of the above embodiment and will not be described in detail here. The grinding assembly 701 includes a swing cover 706, a swing shaft 707, a swing drive member 708, a rotation shaft 709, and a rotation drive member 710. The swing shaft 707 is rotatably connected to the frame 300. Specifically, a first bearing 7071 is fixed to one end of the swing shaft 707 facing the frame 300, and the swing shaft 707 is rotatably connected to the frame 300 via the first bearing 7071. A swing gear 7061 is fixedly connected to the swing cover 706. The fixed connection method between the swing gear 7061 and the swing cover 706 includes but is not limited to welding, one-piece molding, bolt fixing, etc. This application does not limit this, as long as the swing gear 7061 and the swing cover 706 can move synchronously. The swing gear 7061 is generally fan-shaped, with the tooth surfaces of the swing gear 7061 located on the curved surface of the fan-shaped structure. The swing shaft 707 passes through both the swing cover 706 and the swing gear 7061. The rotation axis 7124 of the swing gear 7061 coincides with the axis of the swing shaft 707. It should be noted that the rotation axis 7124 of the swing gear 7061 coincides with the center of the fan-shaped structure. The swing shaft 707 is rotationally connected to the swing cover 706 and the swing gear 7061. Specifically, a second bearing 7072 is fixed to the swing shaft 707, through which the swing shaft 707 is rotationally connected to the swing cover 706 and the swing gear 7061. The rotating shaft 709 is rotatably connected to the end of the swing cover 706 away from the swing shaft 707. Specifically, the swing cover 706 has an escape cavity 7062 therein. One end of the rotating shaft 709 passes through the swing cover 706 and enters the escape cavity 7062, while the other end passes through the swing cover 706 and is exposed to the outside. A third bearing 7091 is fixed to the rotating shaft 709, and the rotating shaft 709 is rotatably connected to the swing cover 706 via the third bearing 7091. A grinding member 711 is fixed to the end of the rotating shaft 709 that passes through the swing cover 706. The grinding member 711 is used to grind materials. The rotation path of the grinding member 711 moving around the swing shaft 707 passes through the grinding station 302.A transmission assembly 712 is provided between the swing shaft 707 and the rotation shaft 709. The transmission assembly 712 is located in the avoidance cavity 7062. The transmission assembly 712 includes but is not limited to a gear train transmission assembly 712, a pulley transmission assembly 712, a sprocket transmission assembly 712, etc. For example, the transmission assembly 712 is a gear train transmission assembly 712. A first gear 7121 is fixed on the shaft body of the swing shaft 707 located in the avoidance cavity 7062. A second gear 7122 is fixed on the shaft body of the rotation shaft 709 located in the avoidance cavity 7062. A third gear 7123 is provided between the first gear 7121 and the second gear 7122. A rotating shaft 7124 is coaxially passed through the third gear 7123. The rotating shaft 7124 is fixedly connected to the third gear 7123. The third gear 712 3 and the rotating shaft 7124 are both located in the avoidance cavity 7062, and the two ends of the rotating shaft 7124 are respectively fixed with fourth bearings 7125, and the rotating shaft 7124 is rotatably connected to the swing cover 706 through the fourth bearing 7125 to realize the rotational connection of the third gear 7123 in the swing cover 706. After such arrangement, when the swing shaft 707 rotates, the rotation shaft 709 can be driven to rotate through the transmission of the first gear 7121, the third gear 7123 and the second gear 7122. In addition, in order to facilitate the installation of the corresponding structure in the swing cover 706, the swing cover 706 includes a first cover body 7063 and a second cover body 7064. The first cover body 7063 and the second cover body 7064 are connected in a detachable manner, including but not limited to snap connection, magnetic attraction, bolt connection, snap connection, etc. The swing driving member 708 is a motor, which is fixedly connected to the frame 300. A fourth gear 7081 is fixed on the output shaft of the swing driving member 708. The fourth gear 7081 is engaged with the tooth surface of the swing gear 7061. The swing driving member 708 drives the swing gear 7061 to rotate around the swing axis 707 through the engagement relationship between the fourth gear 7081 and the swing gear 7061. The self-rotating driving component 710 is a motor, which is fixedly connected to the frame 300. A fifth gear 7101 is fixedly connected to the output shaft of the self-rotating driving component 710, and a sixth gear 7073 is fixed to the swing shaft 707. The fifth gear 7101 is engaged with the sixth gear 7073. The self-rotating driving component 710 drives the swing shaft 707 to rotate through the engagement relationship between the fifth gear 7101 and the sixth gear 7073. The swing shaft 707 is then driven by the first gear 7121, the third gear 7123 and the second gear 7122 to drive the self-rotating shaft 709 to rotate, thereby driving the grinding component 711 to rotate.

[0068] When the material needs to be ground, the swing drive member 708 first drives the swing gear 7061 to drive the swing cover 706 to rotate around the swing shaft 707. Due to the gear meshing relationship between the swing gear 7061 and the fourth gear 7081, the swing drive member 708 can achieve stepless adjustment of the rotation angle of the swing cover 706. During the process of the swing cover 706 rotating around the swing shaft 707, it drives the grinding member 711 to move toward the grinding station 302. When the grinding member 711 contacts the material on the grinding station 302, the swing drive member 708 stops driving the swing gear 7061. At this time, the self-rotating drive member 710 starts to operate. The self-rotating drive member 710 drives the swing shaft 707 to rotate through the cooperation of the fifth gear 7101 and the sixth gear 7073. The swing shaft 707 is then driven by the first gear 7121, the third gear 7123 and the second gear 7122 to drive the self-rotating shaft 709 to rotate. The rotation of the rotating shaft 709 drives the grinding member 711 to rotate, and the grinding member 711 grinds the material during the rotation process. In addition, in order to enhance the grinding effect, the rotation direction of the rotating drive member 710 and the first drive assembly 702 can be pre-set so that the rotation direction of the grinding member 711 is opposite to the rotation direction of the material, thereby further improving the grinding effect. It should be noted that when the grinding member 711 contacts the material on the grinding station 302, it corresponds to the first position of the above-mentioned grinding mechanism 700, and when the grinding member 711 does not contact the material on the grinding station 302, it corresponds to the second position of the above-mentioned grinding mechanism 700.

[0069] In addition to the above functions, the swing shaft 707 serves as both the swing center of the swing arm and the power transmission shaft of the self-rotating drive member 710. This arrangement can greatly reduce the space occupied by the grinding mechanism 700, and can also fix the self-rotating drive member 710 on the frame 300. In this way, the self-rotating drive member 710 does not need to move with the swing cover 706, reducing the possibility of damage to the cables on the self-rotating drive member 710 due to excessive movement and improving its service life.

[0070] In one embodiment, two groups of grinding mechanisms 700 are sequentially provided along the conveying direction of the second conveyor line 600. Furthermore, the precision of the grinding tools 7012 of the two groups of grinding mechanisms 700 increases sequentially along the conveying direction of the second conveyor line 600. Correspondingly, two groups of grinding stations 302 are also provided, with the two groups of grinding stations 302 corresponding one to the two groups of grinding mechanisms 700. With this arrangement, the material can be coarsely ground first and then finely ground. Coarse grinding can quickly remove most of the excess material on the workpiece surface, shortening the grinding time, while fine grinding can improve the precision and smoothness of the ground portion of the material.

[0071] See Figure 12 and Figure 15In one embodiment, a dust collection hood 705 is positioned near the grinding station 302. The hood 705 includes a dust collection chamber 7051, which is connected to an external dust collection device via a hose. The grinding station 302 is at least partially located within the dust collection chamber 7051. The dust collection device generates a negative pressure in the dust collection chamber 7051 to absorb debris generated by the grinding mechanism 700 during grinding. This arrangement allows the dust collection device to absorb debris generated during the grinding process, thereby preventing environmental pollution.

[0072] See Figure 15 In one embodiment, the dust hood 705 includes an upper cover 7052 and a lower cover 7053. The lower cover 7053 is fixedly connected to the frame 300, and the upper cover 7052 is connected to the first mounting seat 7022. When the output end of the fourth driving member 7025 moves to the lowest position, the first mounting seat 7022 drives the upper cover 7052 to press against the lower cover 7053 to form a dust collection chamber 7051. With this arrangement, the upper cover 7052 can be prevented from interfering with the transportation of materials on the transportation path of the second conveyor line 600, so that the materials can be smoothly placed on the grinding station 302. In addition, the dust hood 705 is provided with an avoidance groove 7054 on the side facing the grinding tool 7012, through which the grinding tool 7012 can move to the first position.

[0073] See Figure 2 and Figure 12 In one embodiment, a burr removal station 304 is further provided on the frame 300, and the burr removal station 304 is located between the grinding station 302 and the second inspection station 303. It should be noted that the structures of the burr removal station 304 and the grinding station 302 are the same, and the only difference is the fixed position on the frame 300. The structure of the burr removal station 304 refers to the grinding station 302, and will not be repeated here. In addition, the transport rod 601 also passes between the two second support seats 3021 of the burr removal station 304. The process of transporting the material from the grinding station 302 to the burr removal station 304 is the same as the process of transporting the material from the placement station 607 to the grinding station 302, and will not be repeated here. The armature commutator back-end production line also includes a burr removal mechanism 800, and the burr removal mechanism 800 is arranged between the grinding mechanism 700 and the second inspection mechanism 900. After the material is coarsely and finely ground by the grinding mechanism 700 , a small amount of burrs (such as small-sized debris) may be absorbed by the ground part of the material. The purpose of setting the burr removal mechanism 800 is to remove the burrs of the material located at the burr removal station 304 .

[0074] See Figure 12In one embodiment, the burr removal mechanism 800 includes a deburring assembly 801 and a second drive assembly 802. The deburring assembly 801 includes a fifth drive member 8011 and a deburring member 8012. The fifth drive member 8011 is a motor, and the deburring member 8012 is a disc brush. The deburring member 8012 is connected to the output end of the fifth drive member 8011. The fifth drive member 8011 drives the deburring member 8012 to rotate, thereby removing burrs from the material. The second drive assembly 802 is located above the deburring station 304 and is used to drive the material located at the deburring station 304 to rotate. The rotation axis 7124 of the deburring member 8012 is perpendicular to the rotation axis of the material. With this arrangement, the rotation of the material and the brush occur synchronously, which can improve the deburring effect.

[0075] See Figure 12 In one embodiment, to improve deburring efficiency, two deburring stations 304 are provided. The fifth drive member 8011 is a dual-axis motor. An extension shaft 8013 is coaxially fixed to each output shaft of the fifth drive member 8011. A deburring member 8012 is fixedly connected to each extension shaft 8013 at the end away from the fifth drive member 8011. The deburring members 8012 on the two extension shafts 8013 correspond one to each of the two deburring stations. This allows the fifth drive member 8011 to simultaneously drive the two deburring members 8012 to rotate, allowing them to simultaneously deburr materials at both deburring stations, thereby improving deburring efficiency.

[0076] See Figure 12In one embodiment, the second drive assembly 802 includes a second mounting base 8021, a sixth drive member 8022, a second pulley set 8023, a second synchronous belt 8024, and a seventh drive member 8025. The second pulley set 8023 includes a plurality of pulleys, each of which is rotatably connected to the second mounting base 8021. The second synchronous belt 8024 is wound around the plurality of pulleys of the second pulley set 8023. The sixth drive member 8022 is a motor, which is fixedly connected to the second mounting base 8021. The output shaft of the sixth drive member 8022 is coaxially fixed to any pulley in the second pulley set 8023, and the sixth drive member 8022 can drive the second synchronous belt 8024 to rotate. The seventh drive member 8025 is fixedly connected to the frame 300. The seventh drive member 8025 is a pneumatic or hydraulic cylinder, and its output end is movable in the vertical direction. The second mounting base 8021 is fixedly connected to the output end of the seventh drive member 8025 and is located above the deburring station. When the output end of the seventh drive member 8025 moves to the lowest position, the second mounting base 8021 drives the second synchronous belt 8024 to press the material on the deburring station 304. During the rotational motion of the second synchronous belt 8024, the friction force drives the material to rotate. Furthermore, when the second synchronous belt 8024 presses the material on the deburring station 304, the deburring member 8012 simultaneously contacts the portion of the material on the deburring station 304 where the burrs are to be deburred.

[0077] See Figure 2 and Figure 16 In one embodiment, the armature commutator back-end production line further includes a second detection mechanism 900, and the second detection mechanism 900 includes a sensor system 901. The sensor system 901 is used to identify the image information and / or three-dimensional information of the material placed on the second detection station 303. It should be noted that the image information refers to the image with the material, and the three-dimensional information refers to the three-dimensional coordinate information of the surface of the material. Specifically, the memory 202 of the control system 200 pre-stores the image of the material after the grinding process and / or the three-dimensional coordinate information of the material after the grinding process. After the sensor system 901 recognizes the image information and / or three-dimensional information of the material, it will be compared with the image and / or three-dimensional coordinate information pre-stored in the memory 202. When the comparison result is within the error range, it indicates that the grinding of the material meets the requirements. Otherwise, it indicates that the grinding of the material is unqualified.

[0078] See Figure 16In one embodiment, the second detection mechanism 900 further includes a third drive assembly 902, which includes a third mounting seat 9021, an eighth drive member 9022, a third pulley set 9023, a third synchronous belt 9024, and a ninth drive member 9025. The third pulley set 9023 includes a plurality of pulleys, each of which is rotatably connected to the third mounting seat 9021. The third synchronous belt 9024 is wound around the plurality of pulleys of the third pulley set 9023. The eighth drive member 9022 is a motor, which is fixedly connected to the third mounting seat 9021. The output shaft of the eighth drive member 9022 is coaxially fixed to any pulley in the third pulley set 9023, and the eighth drive member 9022 can drive the second synchronous belt 8024 to rotate. The ninth driving member 9025 is fixedly connected to the frame 300. The ninth driving member 9025 is a cylinder or an oil cylinder, and its output end can move in the height direction. The third mounting base 9021 is fixedly connected to the output end of the ninth driving member 9025, and the third mounting base 9021 is located above the second detection station 303. When the output end of the ninth driving member 9025 moves to the lowest position, the third mounting base 9021 drives the third synchronous belt 9024 to compact the material on the second detection station 303. The third synchronous belt 9024 drives the material to rotate by friction during the rotary motion. During the rotation of the material, the sensor system 901 identifies the image information and / or three-dimensional information of the material. Preferably, the sensor system 901 of the present application is used to identify the image information of the material placed on the second detection station 303. In contrast, the material image after the grinding process is pre-stored in the memory 202 of the control system 200. After being set like this, image information can be obtained during the rotation of the material, and 360 ° of all-round recognition of the material can be performed, thereby improving the recognition accuracy.

[0079] See Figure 16In one embodiment, the second detection mechanism 900 further includes a grabbing assembly 903, and the grabbing assembly 903 includes a fourth conveyor line 9031, a tenth driving member 9032, and a grabbing member 9033. The fourth conveyor line 9031 is a synchronous belt 403 conveyor line. The fourth conveyor line 9031 has the same structure as the first conveyor line 400. The only difference between the two is the setting position and the transportation direction, which will not be described in detail here. The tenth driving member 9032 is fixedly connected to the synchronous belt 403 of the fourth conveyor line 9031. The connection method between the tenth driving member 9032 and the fourth conveyor line 9031 is the same as the connection method between the first driving member 5013 and the third conveyor line 5011, which will not be described in detail here. The tenth driving member 9032 is a pneumatic or hydraulic cylinder and is movable in the vertical direction. A fourth extension plate 9034 is fixedly connected to the output end of the tenth driving member 9032. A grabbing member 9033 is fixedly connected to the fourth extension plate 9034. The grabbing member 9033 is fixedly connected to the output end of the tenth driving member 9032 via the fourth extension plate 9034. A second electromagnet 9035 is connected to the grabbing member 9033 and is used to grab material from the second inspection station 303. The second electromagnet 9035 is electrically connected to the control system 200, which can control the on and off of the second electromagnet 9035. It should be noted that the process of grabbing material by the grabbing assembly 903 is the same as the process of picking up material by the first grabbing arm 5012, and will not be further described here. After the sensor system 901 completes the material identification, if the material meets the requirements, the grabbing assembly 903 grabs the material to the qualified product placement area. If the material fails to meet the requirements, the grabbing assembly 903 grabs the material to the unqualified product placement area. In addition, if the conductivity test result of the material at the first inspection station is unqualified, the material will be recorded by the control system 200 and transported to the second inspection station 303 by the second conveyor line 600. The unqualified material is then grabbed by the grabbing assembly 903 and placed in the unqualified product placement area. In other embodiments, another unqualified placement area can also be set near the third conveyor line 5011, and a fourth stop point can be set on the second conveyor line 600. The fourth stop point is located above the unqualified placement area near the third conveyor line 5011. When the conductivity test result of the material at the first inspection station is unqualified, the first grabbing arm 5012 directly picks up the material and places it in the unqualified placement area near the third conveyor line 5011.

[0080] See Figure 16In one embodiment, the third drive assembly 902 further includes an eleventh drive member 9026, which is a pneumatic or hydraulic cylinder. The eleventh drive member 9026 is fixedly connected to the output end of the ninth drive member 9025 and is capable of horizontal movement. The third mounting base 9021 is fixedly connected to the output end of the tenth drive member 9032. Before the grabbing member 9033 uses the second electromagnet 9035 to grab the material on the second inspection station 303, the eleventh drive member 9026 drives the third mounting base 9021 away from the material on the second inspection station 303, thereby fully exposing the material and facilitating the second electromagnet 9035 to grab the material.

[0081] It should be noted that the materials in this application need to be positioned multiple times when they are at the first inspection station 301, the placement station 607, the temporary station 606, the grinding station 302, and the second inspection station 303, as well as during the material transfer process. In order to achieve automatic positioning, position sensors are also provided at corresponding positions on the armature commutator downstream production line. The photoelectric sensor 5017 provided at the position where the first grabbing arm 5012 grabs the material on the above-mentioned first conveyor line 400 also belongs to a position sensor. Position sensors include but are not limited to DToF sensors, IToF sensors, lidars, line laser sensors, monocular cameras, multi-cameras, ultrasonic sensors, Hall sensors, etc. The working principle of position sensors is prior art. Those skilled in the art can set position sensors at corresponding positions as needed, and this application will not elaborate on them one by one.

[0082] In the present application, the first detection mechanism 500 can automatically detect the conductivity of the material, the grinding mechanism 700 can automatically grind the material, the burr removal mechanism 800 can automatically remove burrs on the ground material, and the second detection mechanism 900 can automatically detect the smoothness of the ground part of the material. At the same time, the conveying path of the first conveyor line 400 and the second conveyor line 600 can realize the automatic conveying of the material in the first detection mechanism 500, the grinding mechanism 700, the burr removal mechanism 800, and the second detection mechanism 900. Therefore, through the above technical solution, the two subsequent processes of the conductive performance detection of the armature and the surface grinding of the armature commutator can be fully automated, thereby improving the production efficiency of the armature.

[0083] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, any equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
