Abstract
Description
Technical Field
[0001] This invention relates to the technical field of armature manufacturing, and particularly to a post-production line for armature commutators. Background Technology
[0002] The armature, also known as the rotor, in a brushless DC motor is the core component that generates induced electromotive force and electromagnetic torque, realizing the electromechanical energy conversion. The armature includes the armature core, armature windings, commutator, and shaft. In the later stages of armature manufacturing, the conductivity of the commutator and windings needs to be tested. After meeting the conductivity requirements, the commutator surface needs to be ground to ensure a smooth finish that meets usage standards. Currently, these later stages are typically performed manually, or even separately on multiple production lines, resulting in high manual intervention and low automation, severely impacting armature production efficiency. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the present invention provides an armature commutator downstream production line to solve the problem of low automation in the armature downstream production process and improve the production efficiency of armatures.
[0004] To achieve the above and other related objectives, the present invention provides an armature commutator downstream production line, which includes:
[0005] Along the material conveying direction, the frame is sequentially provided with a first inspection station, a grinding station, and a second inspection station;
[0006] First conveyor line;
[0007] The first detection mechanism includes a pickup component and a detection component. The pickup component is used to pick up the material on the first conveyor line and place the material on the first detection station. The detection component is used to perform conductivity detection on the material on the first detection station.
[0008] The second conveyor line passes sequentially through the grinding station and the second inspection station. The second conveyor line has a lifting position and a lowering position. In the lifting position, the second conveyor line is higher than the grinding station and the second inspection station to transport the material. In the lowering 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.
[0009] A grinding mechanism is mounted on the frame and has 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; in the second position, the grinding mechanism is away from the grinding station.
[0010] The second detection mechanism includes a sensor system for identifying image information and / or three-dimensional information of the material placed on the second detection station.
[0011] Compared with the prior art, the above technical solution has the following advantages: the first detection mechanism can automatically detect the conductivity of the material, the grinding mechanism can automatically grind the material, the second detection mechanism can automatically detect the smoothness of the ground part of the material, and the conveying paths of the first and second conveying lines can realize the automated conveying of the material in the first detection mechanism, the grinding mechanism, and the second detection mechanism. Therefore, through the above technical solution, the two subsequent processes of armature conductivity detection and armature commutator surface grinding can be fully automated, improving the production efficiency of the armature.

[0039] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.
[0040] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0041] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the 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 embodiments of the invention.
[0042] To achieve automated control as described in this invention, the armature commutator downstream production line provided by this invention includes a control system 200, see reference. Figure 1The control system 200 includes a processor 201 and a memory 202 communicatively connected to the processor 201. The memory 202 and the processor 201 can be connected via a bus 203. The memory 202 stores computer programs, and the processor 201 executes 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 described in detail here.
[0043] See Figure 2 The armature commutator downstream production line also includes a frame 300, which is constructed from metal profiles (such as aluminum profiles) and is used to support and install the components that make up the armature commutator downstream production line. The frame 300 can be placed directly on the ground and fixed to the ground by its own weight, or it can be fixed to the ground by anchor bolts.
[0044] See Figure 3 Multiple conveyor lines are installed on the frame 300 to automate the transport of materials (armatures to be processed). Along the material transport direction, a first inspection station 301, a grinding station 302, and a second inspection station 303 are sequentially fixedly connected to the frame 300. During transport, the material is placed sequentially 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 conductivity of the material (e.g., 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 parts of the material is tested at the second inspection station 303.
[0045] See Figure 4 and Figure 5For example, the first inspection station 301 includes a first support base 3011, a first rotating roller 3012, and a first motor 3013. The first support base 3011 is fixedly connected to the frame 300. The first rotating roller 3012 includes a connecting end connected to the first support base 3011 and a free end away from the first support base 3011. The connecting end passes through the first support base 3011 and is rotatably connected to the first support base 3011 via a bearing. The free end extends away from the first support base 3011 and is suspended in the air. Two first rotating rollers 3012 are arranged side by side in a horizontal direction, and materials 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 base 3011. The output end of the first motor 3013 is coaxially fixed with a drive pulley. The ends of the two first rotating rollers 3012 passing through the connecting ends of the first support base 3011 are respectively fixed with driven pulleys. A synchronous belt 403 is wound around the drive pulley and the two driven pulleys. When material is placed between the two first rotating rollers 3012, if the material becomes skewed, the first motor 3013 can be started. The first motor 3013 drives the two driven pulleys to rotate via the drive pulley, and the two driven pulleys then drive the two first rotating rollers 3012 to rotate in the same direction, causing the material to follow the rotation of the two first rotating rollers 3012. During the rotation of the material, the position and orientation of the material can be adjusted so that the axis of the material is parallel to the axis of the first rotating rollers 3012.
[0046] See Figure 4 and Figure 5In addition, to detect whether the material is flush on the two first rotating rollers 3012, a sensing system 3014 is also provided on the first support 3011. The sensing system 3014 is one or a combination of a laser sensor and a camera. For example, the sensing system 3014 is a laser sensor, with the emitting end of the laser sensor facing the area of the two first rotating rollers 3012 used for placing the material. When the material is placed on the two first rotating rollers 3012, the laser sensor emits a laser beam towards the material. The laser beam is reflected on the surface of the material, and the reflected laser beam is received again by the laser sensor. The laser sensor performs data analysis on the received reflected laser to obtain the current coordinate information of the material. Reference coordinates are pre-stored in the memory 202 of the armature commutator downstream production line. The current coordinate information is compared with the reference coordinate information to determine whether the material is level on the two first rotating rollers 3012. If the current coordinate information is the same as the reference coordinate information or within the error range, it means that the material is level on the two first rotating rollers 3012; otherwise, it means that the material is not level on the two first rotating rollers 3012. When the material is not level on the two first rotating rollers 3012, the control system 200 controls the first motor 3013 to start to adjust the position of the material. In other examples, the sensing system 3014 is a camera, and the image acquisition end of the camera is facing the area of the two first rotating rollers 3012 used to place the material. When the material is placed on the two first rotating rollers 3012, the camera acquires the 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 level 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 level on the two first rotating rollers 3012; otherwise, it means that the material is not level on the two first rotating rollers 3012. When the material is not level on the two first rotating rollers 3012, the control system 200 controls the first motor 3013 to start to adjust the position of the material. It should be noted that the above-mentioned camera includes, but is not limited to, monocular cameras, multi-view cameras, fisheye cameras, CCD sensors, high-definition cameras, etc. Any camera that can realize image acquisition and cooperate with the control system 200 to generate image information is acceptable. This application does not limit the specific type of camera.
[0047] See Figure 3 and Figure 6The grinding station 302 includes two opposing second support seats 3021, which are fixedly connected to the frame 300. Bearings 3022 are rotatably connected to the opposing end faces of the two second support seats 3021. Each second support seat 3021 has two bearings 3022 arranged in pairs on its end face. One end of the material is supported between the upper surfaces of the two bearings 3022 on one second support seat 3021, and the other end of the material is supported between the upper surfaces of the two bearings 3022 on the other second support seat 3021. The bearings 3022 on the end faces of the second support seats 3021 improve the smoothness of material rotation on the second support seats 3021.
[0048] The second inspection station 303 and the grinding station 302 have the same structure. The only difference is the fixed position on the frame 300. The structure of the second inspection station 303 is the same as that of the grinding station 302, and will not be described again here.
[0049] See Figure 7 The armature commutator downstream production line also includes a first conveyor line 400, which is a synchronous belt 403 conveyor line. The synchronous belt 403 conveyor line includes a support 401 and a second motor 402. One end of the support 401 is rotatably connected to a drive pulley, and the other end is rotatably connected to a driven pulley. A synchronous belt 403 is wound around the drive and driven pulleys. The second motor 402 is fixedly connected to the end of the support 401 near the drive pulley. The output end of the second motor 402 is coaxially fixed with the drive pulley and is used to drive the drive 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 movement of the synchronous belt 403 achieves the transport of the materials. One end of the first conveyor line 400 is located near the first inspection station 301, so that materials can be transported to a position near the first inspection station 301 via the first conveyor line 400.
[0050] See Figure 2 , Figures 8-10 The armature commutator downstream production line also includes a first inspection mechanism 500. The first inspection mechanism 500 includes a pickup component 501 and an inspection component 502. The pickup component 501 is used to pick up the material on the first conveyor line 400 and place the material on the first inspection station 301. The inspection component 502 is used to perform conductivity detection on the material on the first inspection station 301.
[0051] See Figure 8In one embodiment, the picking component 501 includes a third conveyor line 5011 and a first gripping 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, differing only in its location and transport direction, which will not be elaborated upon here. The first gripping arm 5012 is connected to the third conveyor line 5011. Specifically, the first gripping arm 5012 is connected to the synchronous belt 403 of the third conveyor line 5011. The third conveyor line 5011 can drive the first gripping arm 5012 to move between the first conveyor line 400 and the first inspection station 301, so as to transport materials from the first conveyor line 400 to the first inspection station 301 using the first gripping arm 5012.
[0052] See Figure 8 In one embodiment, the first gripping 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. The first driving member 5013 is fixedly connected to the first mounting base 503 and 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 it can achieve relative fixation between the second driving member 50181 and the synchronous belt 403 of the third conveyor line 5011. 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.
[0053] See Figure 8This application embodiment uses the example of a first driving member 5013 connected to a synchronous belt 403 of a third conveyor line 5011 via a first mounting base 503. The third conveyor line 5011 can drive the first driving member 5013 to move between the first conveyor line 400 and the first detection station 301 by driving the first mounting base 503. The first driving member 5013 is a cylinder or hydraulic 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 chuck 5014 is fixedly connected to the first extension plate 5015 and 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 chuck 5014. The first electromagnet 5016 is electrically connected to the control system 200, and the control system 200 can control the on / off state of the first electromagnet 5016. When the first electromagnet 5016 is energized, it can attract materials through magnetic force to pick them up from the first conveyor line 400 to the first detection station 301; when the first electromagnet 5016 is de-energized, it no longer has magnetic force and cannot attract materials.
[0054] When it is necessary to transfer the material on the first conveyor line 400 to the first inspection station 301, the first gripping arm 5012 first moves to above the first conveyor line 400 via the third conveyor line 5011. When the magnetic chuck 5014 is exactly above the material, the first driving member 5013 drives the first electromagnet 5016 of the magnetic chuck 5014 to descend to be in contact with the surface of the material. At the same time, the first electromagnet 5016 is energized to generate a magnetic force, and the material is picked up by the magnetic force. Next, while keeping the first electromagnet 5016 energized, the first drive member 5013 drives the magnetic chuck 5014 to rise to its highest position. Then, the first gripping arm 5012 carries the picked-up material and moves it above the first detection station 301 via the third conveyor line 5011. When the magnetic chuck 5014 is exactly above the first detection station 301, the first drive member 5013 drives the magnetic chuck 5014 to descend until the material falls between the upper surfaces of the two first rotating rollers 3012. Then, the first electromagnet 5016 is de-energized to release the material from the grasp, and the first drive member 5013 drives the magnetic chuck 5014 to rise, so that the material remains between the upper surfaces of the two first rotating rollers 3012.
[0055] It should be noted that the third conveyor line 5011 has a first stopping point and a second stopping point along its conveying direction. The first stopping point is located directly above the position on the first conveyor line 400 where the first gripping arm 5012 grips the material, and the second stopping point is located directly above the first inspection station 301. When the third conveyor line 5011 moves the first gripping arm 5012 to the first stopping point, the magnetic suction seat 5014 is exactly located directly above the position on the first conveyor line 400 where the first gripping arm 5012 grips the material; when the third conveyor line 5011 moves the first gripping arm 5012 to the second stopping point, the magnetic suction seat 5014 is exactly located directly above the first inspection station 301. (See reference...) Figure 7 A photoelectric sensor 5017 is provided at the position where the first gripping arm 5012 grips the material on the first conveyor line 400. 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.
[0056] See Figure 9 and Figure 10After the material is positioned between the two first rotating rollers 3012, the detection component 502 detects the conductivity of the material. In one embodiment, the detection component 502 is located close to the first detection station 301, and includes a chuck base 5021 and jaws 5022. The chuck base 5021 is mounted on the frame 300, and has a plurality of moving slots 5023 arranged circumferentially on the chuck base 5021. The extension lines of each moving slot 5023 in the length direction converge at a point, which is the center of the circle formed by the circumferential distribution of the moving slots 5023. A jaw 5022 is provided in each moving slot 5023, meaning that multiple jaws 5022 are also provided circumferentially on the chuck. One end of the chuck 5022 is located within the moving groove 5023. The dimension of the chuck 5022 along the length of the moving groove 5023 is smaller than that of the moving groove 5023, thereby enabling the chuck 5022 to move along the length of the moving groove 5023. The end of the chuck 5022 away from the moving groove 5023 is an extension end, which extends toward the first inspection station 301. A take-up and put-down tray 5024 is provided on the side of the chuck base 5021 opposite to the first inspection station 301. The take-up and put-down tray 5024 is rotatably connected to the chuck base 5021, and the rotation center of the take-up and put-down tray 5024 is coaxial with the center of the circle formed by the circumferential distribution of the moving grooves 5023. Multiple take-up and put-down slots 5025 are provided circumferentially on the take-up and put-down tray 5024. Each take-up and put-down slot 5025 corresponds to a moving slot 5023. The length direction of the take-up and put-down slot 5025 forms an angle b with the length direction of the moving slot 5023. Specifically, the length of the line connecting one end of the take-up and put-down slot 5025 to the rotation center of the take-up and put-down tray 5024 is greater than the length of the line connecting the other end of the take-up and put-down slot 5025 to the rotation center of the take-up and put-down tray 5024. Furthermore, the lines connecting one end of the take-up and put-down slot 5025 to the rotation center of the take-up and put-down tray 5024 and the other end of the take-up and put-down slot 5025 to the rotation center of the take-up and put-down tray 5024 form an angle α, which is the rotatable angle of the take-up and put-down tray 5024. The angle b is set according to actual needs, as long as the take-up and put-down slot 5025 and the moving slot 5023 always have a through take-up and put-down hole 50251 when the take-up and put-down tray 5024 rotates within the range of angle α. An extension rod 5026 is fixed on the end face of the claw 5022 away from the extension end. The extension rod 5026 passes through the take-up and release hole 50251 formed by the superposition of the take-up and release groove 5025 and the moving groove 5023.
[0057] See Figure 9 and Figure 10A rotary drive component 5027 is fixedly connected to the chuck base 5021. The rotary drive component 5027 can be a rotary cylinder or a motor. The output end of the rotary drive component 5027 is coaxially fixed to the rotation center of the take-up and put-down tray 5024. In this way, the take-up and put-down tray 5024 can be driven to rotate within the included angle α by the rotary drive component 5027. A detection probe 5028 is provided on the extension end of each jaw 5022. Specifically, a mounting hole is provided through the extension end. The through direction of the mounting hole is consistent with the length direction of the moving groove 5023. The detection probe 5028 passes through and is interference-fitted in the mounting hole. The detection end of the detection probe 5028 is located inside the jaw 5022.
[0058] Through the cooperation of the aforementioned rotary drive 5027, take-up / release groove 5025, and moving groove 5023, multiple jaws 5022 have both a retracted and a dispersed state on the chuck. Specifically, when it is necessary to test the conductivity of the material, the rotary drive 5027 drives the take-up / release plate 5024 to rotate in a first direction, so that the take-up / release hole 50251 formed by the take-up / release groove 5025 and the moving groove 5023 gradually gets closer to the rotation center of the take-up / release plate 5024. This gradual approach causes each jaw 5022 to move along the length direction of the moving groove 5023, so that each jaw 5022 gradually retracts towards the rotation center of the take-up / release plate 5024, thereby causing the detection ends of the detection probes 5028 on each jaw 5022 to contact the part of the material to be tested. Then the detection probes 5028 are activated to test the conductivity of the material. After the conductivity test of the material is completed, the rotary drive 5027 drives the take-up and release tray 5024 to rotate in the second direction. This causes the take-up and release hole 50251 formed by the take-up and release groove 5025 and the moving groove 5023 to gradually move further away from the rotation center of the take-up and release tray 5024. This gradual movement causes each jaw 5022 to move along the length of the moving groove 5023, so that each jaw 5022 gradually disperses relative to the rotation center of the take-up and release tray 5024. Consequently, the detection ends of the detection probes 5028 on each jaw 5022 gradually move away from the detection area of the material, thus putting multiple detection probes 5028 into a non-detection state. It should be noted that the first direction and the second direction mentioned above are two opposite rotation directions. Furthermore, using detection probes 5028 to detect the conductivity of the material is existing technology and will not be elaborated upon here.
[0059] See Figure 9 and Figure 10In one embodiment, the detection component 502 further includes a drive source 5029, which is fixedly connected to the frame 300. The output end of the drive source 5029 is movable in directions toward and away from the first detection station 301. A chuck holder 5021 is slidably connected to the frame 300 and is connected to the output end of the drive source 5029. Specifically, when conductivity testing of the material is required, the drive source 5029 drives the chuck holder 5021 to move toward the first detection station 301; when conductivity testing of the material is completed, the drive source 5029 drives the chuck holder 5021 to move away from the first detection station 301.
[0060] See Figure 9 and Figure 10 A guide rail pair is provided on the bottom surface of the chuck base 5021. 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. The length direction of the guide rail (i.e., the guiding direction of the guide rail) points towards the first inspection station 301. The guide rail pair improves the stability of the chuck base 5021 when moving towards and away from the first inspection station 301. 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 set or no less than two sets. The number of guide rail pairs is not limited, as long as it can achieve stable sliding of the chuck base 5021.
[0061] See Figure 9 and Figure 10 The drive source 5029 can be a pneumatic cylinder or a hydraulic cylinder. In this case, the drive source 5029 is fixedly connected to the frame 300, and the output end of the drive 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 drive source 5029, so that the chuck seat 5021 can be driven to approach and move away from the first detection station 301 by the drive source 5029. In other examples, the drive source 5029 can also be a combination of a motor and a lead screw assembly. In this case, the lead screw assembly includes a guide lead screw and a nut seat. The motor is fixedly connected to the frame 300, and the axis of the motor's output shaft is aligned with the first detection station 301. The guide lead screw is coaxially connected to the motor's output shaft. The nut seat is fixedly connected to the bottom surface of the chuck seat 5021. The nut seat is sleeved on the guide lead screw and threadedly engaged with it. The nut seat is equivalent to the output end of the drive source 5029. Under the threaded feed of the guide lead screw, the nut seat can move towards and away from the first detection station 301. With this configuration, the chuck seat 5021 can be driven to approach and move away from the first detection station 301 through the cooperation of the motor and the lead screw assembly.
[0062] After the material is picked up by the first gripping arm 5012 and placed at the first detection station 301, and the two first rotating rollers 3012 adjust the material's position, the drive source 5029 drives the chuck holder 5021 to move toward the first detection station 301, so that the extended ends of each jaw 5022 on the chuck holder 5021 surround the area of the material to be detected. Next, the rotary drive 5027 drives each jaw 5022 to a retracted state, so that the conductivity of the material can be detected using the detection probe 5028. After completing the conductivity detection, the rotary drive 5027 drives each jaw 5022 to a dispersed state, and then the drive source 5029 drives the chuck holder 5021 to move away from the first detection station 301 until the chuck holder 5021, carrying each jaw 5022, is completely away from the material.
[0063] 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 testing components 502 are also arranged side-by-side on the frame 300 along the conveying direction of the third conveyor line 5011. Each testing component 502 corresponds one-to-one with a first testing station 301. Correspondingly, two second stopping points are also provided on the third conveyor line 5011. With this arrangement, the two first testing stations 301 and the two testing components 502 can perform conductivity testing independently, greatly improving the efficiency of conductivity testing.
[0064] See Figure 3 and Figure 11 The armature commutator downstream production line also includes a second conveyor line 600, which sequentially passes through a grinding station 302 and a second inspection station 303. The second conveyor line 600 has a lifting position and a lowering position. In the lifting position, the second conveyor line 600 is higher than the grinding station 302 and the second inspection station 303 to transport materials; in the lowering position, the second conveyor line 600 is lower than 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.
[0065] See Figure 11 For example, the second conveyor line 600 includes a transport rod 601, a lifting member 602, and a telescopic member 603. The transport rod 601 is a long strip-shaped rod, with one end close to the first inspection station 301 and the other end extending horizontally, passing at least sequentially through the grinding station 302 and the second inspection station 303. The transport rod 601 is simultaneously located 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. The transport rod 601 can extend and retract horizontally between the two second support seats 3021 of the grinding station 302 and the two second support seats 3021 of the inspection station 303, and can also rise and fall vertically.
[0066] See Figure 11 The transport rod 601 is slidably fitted with a guide seat 604, which is located on the bottom surface of the transport rod 601, forming a guide rail pair with the transport rod 601. The lifting component 602 is a cylinder or hydraulic cylinder, and its body is fixedly connected to the frame 300. The telescopic end of the lifting component 602 can move up and down in the height direction, and the guide seat 604 is fixedly connected to the telescopic end of the lifting component 602. In this way, the lifting component 602 realizes the lifting and lowering of the guide seat 604 in the height direction, so as to realize the lifting and lowering of the transport rod 601 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 along the height direction. In addition, to improve the stability of the transport rod 601 in the transport direction and its lifting stability in the height direction, multiple guide seats 604 are provided along the transport direction of the transport rod 601, and multiple lifting components 602 are also provided along the transport direction of the transport rod 601, with each guide seat 604 and lifting component 602 corresponding to one another. The telescopic component 603 is a cylinder or hydraulic cylinder, and the telescopic end of the telescopic component 603 extends in the same direction as the transport rod 601. The end of the telescopic component 603 away from its telescopic end is fixedly connected to any of the aforementioned guide seats 604, and a connecting plate 605 is fixedly connected to the telescopic end of the telescopic component 603. The end of the connecting plate 605 away from the telescopic cylinder is fixedly connected to the transport rod 601. In this way, the telescopic component 603 enables the transport rod 601 to extend and retract horizontally 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 workstation 606 is fixedly connected to the top surface of the transport rod 601. Multiple temporary workstations 606 are provided along the length of the transport rod 601. Each temporary workstation 606 includes a third support 6061, which is fixedly connected to the transport rod 601. The third support 6061 has a material slot 6062 for placing materials on the side opposite to the transport rod 601.
[0067] See Figure 3 and Figure 8 In one embodiment, the picking component 501 further includes a second gripping arm 5018, which is connected to a third conveyor line 5011. Specifically, the second gripping arm 5018 is connected to the synchronous belt 403 of the third conveyor line 5011. The third conveyor line 5011 can drive the second gripping arm 5018 to move between the first inspection station 301 and the second conveyor line 600, so as to use the second gripping arm 5018 to transport materials from the first inspection station 301 to the second conveyor line 600.
[0068] See Figure 8In one embodiment, the second gripping arm 5018 includes a second drive member 50181 and a robotic arm 50182. The second drive member 50181 is connected to the third conveyor line 5011. Specifically, the second drive member 50181 can be fixedly connected to the first mounting base 503, or it can be fixedly connected to the synchronous belt 403 of the third conveyor line 5011. Alternatively, a second mounting base can be fixedly connected to the synchronous belt 403 of the third conveyor line 5011, and the second drive member 50181 can be fixedly connected to the second mounting base. As long as the relative fixation between the second drive member 50181 and the synchronous belt 403 of the third conveyor line 5011 can be achieved, this application does not limit the fixing method between the first drive member 50181 and the synchronous belt 403 of the third conveyor line 5011.
[0069] See Figure 8 This embodiment of the application takes the example of the second driving component 50181 being connected to the synchronous belt 403 of the third conveyor line 5011 via the first mounting base 503. The third conveyor line 5011 can drive the second driving component 50181 to move between the first detection station 301 and the second conveyor line 600 by driving the first mounting base 503. The second driving component 50181 is a cylinder or hydraulic cylinder. The output end of the second driving component 50181 can move in the height direction. A third extension plate 50183 is fixedly connected to the output end of the second driving component 50181. A robot arm 50182 is fixedly connected to the third extension plate 50183. The robot arm 50182 is connected to the output end of the second driving component 50181 via the third extension plate 50183. The robot arm 50182 is used to pick up materials from the first detection station 301 to the second conveyor line 600. The robotic arm 50182 is electrically connected to the control system 200. It should be noted that the robotic arm 50182 is a conventional structure in the field and will not be described in detail in this application.
[0070] See Figure 3 and Figure 8Along the conveying direction of the third conveyor line 5011, the second gripping arm 5018 is closer to the second conveyor line 600 than the first gripping arm 5012. The third conveyor line 5011 also has a third stopping point along its conveying direction, which is located directly above the second conveyor line 600. The relative positions of the first gripping arm 5012 and the second gripping arm 5018 are preset to meet the following conditions: when the first gripping arm 5012 is located directly above the position on the first conveyor line 400 where it grips the material, the second gripping arm 5018 is located directly above the first inspection station 301 near the first conveyor line 400; when the first gripping arm 5012 is located directly above the first inspection station 301 near the first conveyor line 400, the second gripping arm 5018 is located directly above the first inspection station 301 near the second conveyor line 600; when the first gripping arm 5012 is located directly above the first inspection station 301 near the second conveyor line 600, the second gripping arm 5018 is located directly above the second conveyor line 600. This arrangement improves the material transfer efficiency between the first conveyor line 400, the first inspection station 301, and the second conveyor line.
[0071] 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. The robot arm 50182 is used to pick up materials from the first inspection station 301 and place them at the placement station 607. A third stopping point is located directly above the placement station 607. The placement station 607 is a temporary material placement station used to temporarily place materials from the first inspection station 301. When the first gripping arm 5012 is located directly above the first inspection station 301 near the second conveyor line 600, the second gripping arm 5018 is located directly above the second conveyor line 600, and the robot arm 50182 of the second gripping arm 5018 is located directly above the placement station 607. It should be noted that the placement station 607 and the grinding station 302 have the same structure, the only difference being their different positions, which will not be described in detail here.
[0072] Thus, after the material is inspected at the first inspection station 301, the second gripping arm 5018 grips the material, and then the third conveyor line 5011 moves the second gripping arm 5018 directly above the second conveyor line 600 until the robotic arm 50182 is directly above the placement station 607. Subsequently, the second gripping arm 5018 lowers the material onto the placement station 607. It should be noted that the process of the second gripping arm 5018 gripping the material from the first inspection station 301 to the placement station 607 is largely the same as the process of the first gripping arm 5012 gripping the material from the first conveyor line 400 to the first inspection station 301. The only differences are the material gripping position, the material placement position, and the material gripping method, which will not be elaborated further in this application.
[0073] Multiple placement stations 607 can be set at the beginning of the second conveyor line 600. If only one placement station 607 is set, when there is already material at the placement station 607, the material located at the first detection station 301 will have to wait until the placement station 607 becomes empty before it can be moved to the first empty placement station. This seriously affects the efficiency of conductivity detection. With multiple placement stations 607 set at the beginning of the second conveyor line 600, the number of placement stations 607 is sufficient. After the material completes the conductivity detection, the second gripping arm 5018 can immediately transfer the material to the placement station 607, reducing the dwell time of the material at the first detection station 301. This improves the continuity of the entire production line and further increases efficiency.
[0074] After the material is transferred to the placement station 607, it awaits transport by the second conveyor line 600 to sequentially enter the grinding station 302 for grinding and 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: With the lifting component 602 maintaining the transport rod 601 in a lowered state, the telescopic component 603 pushes the end of the transport rod 601 near the starting section of the second conveyor line 600 to a position close to the starting section of the second conveyor line 600. Then, the lifting component 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 located at the placement station 607, and the temporary station 606 uses its material slot 6062 to restrict the material on the temporary station 606. Next, while the transport rod 601 remains in the upward state, the telescopic component 603 drives the transport rod 601 to carry the material to the grinding station 302. When the material is exactly above the grinding station 302, the lifting component 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, it is restricted by the grinding station 302 and the material detaches from the temporary station 606. The two ends of the material are respectively attached to 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 materials from the grinding station 302 to the second inspection station 303 is the same as the process of transporting materials from the placement station 607 to the grinding station 302. In both cases, the materials are first lifted from the original station by the transport rod 601, then transported to the designated station by the transport rod 601, and then the transport rod 601 is lowered to leave the materials at the designated station. This application will not elaborate further on the detailed process of transporting materials from the grinding station 302 to the second inspection station 303.
[0075] See Figure 2 , Figure 12 and Figure 13 In one embodiment, the armature commutator downstream production line further includes a grinding mechanism 700, which is mounted on a 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 on the grinding station 302; in the second position, the grinding mechanism 700 is away from the grinding station 302.
[0076] 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 mounting base 7011 and a grinding cutter 7012. The grinding cutter 7012 is detachably connected to the grinding mounting base 7011. The grinding mounting base 7011 is connected to the first feed assembly 703, which drives the grinding mounting base 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 mounting base 7011 is in the first position, the grinding cutter 7012 contacts the surface of the material to be ground, and the first drive assembly 702 drives the material located on the grinding station 302 to rotate, thereby using the grinding cutter 7012 to grind the material.
[0077] See Figure 12 and Figure 13 For example, the grinding mounting base 7011 includes a base body 7013, on which a tool mounting base 7014 is fixedly connected. The tool mounting base 7014 has a mounting groove 7015 on the side facing the grinding station 302. The non-grinding end of the grinding tool 7012 is located within the mounting groove 7015. The connection between the grinding tool 7012 and the mounting groove 7015 is a detachable connection, such as using bolts for fixing. Specifically, the tool mounting base 7014 has a threaded hole communicating with the mounting groove 7015. The bolt is threaded into and passes through the threaded hole, so that the grinding tool 7012 is pressed against the mounting groove 7015 using the bolt. For disassembly, simply unscrew the bolt to remove the grinding tool 7012. The connection between the grinding tool 7012 and the mounting groove 7015 can also be a snap-fit, interference fit, threaded connection, etc. This application does not limit this, as long as a detachable connection between the grinding tool 7012 and the mounting groove 7015 can be achieved. This configuration facilitates the maintenance or replacement of the 7012 grinding tool and improves its reusability.
[0078] See Figure 12 and Figure 13The first feed assembly 703 is disposed between the base 7013 and the frame 300. The first feed assembly 703 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. The first feed screw 7032 is coaxially fixed to the output shaft of the third motor 7031, and its axial direction points towards the grinding station 302. The first screw seat 7033 is fixedly connected to the bottom of the base 7013, and is sleeved on the first feed screw 7032, with a threaded engagement between them. The third motor 7031 drives the first feed screw 7032 to rotate. The threaded engagement between the first feed screw 7032 and the first screw seat 7033 causes 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 mounting base 7011 to move towards and away from the grinding station 302. Thus, the first feed assembly 703 can drive the grinding mounting base 7011 to move towards and away from the grinding station 302. When the base 7013 is close to the grinding station 302 and the grinding tool 7012 is in contact with the surface of the material to be ground, the position of the grinding mounting base 7011 is the first position. Any other position can be the second position. In other examples, the first feed assembly 703 can also be a cylinder or a hydraulic cylinder, which directly drives the grinding mounting base 7011 to move. In addition, in order to improve the movement stability of the grinding mounting base 7011, a guide rail pair is provided between the base body 7013 and the frame 300. This application does not limit the number of guide rail pairs, as long as the stable movement of the second base body 7017 can be achieved.
[0079] See Figure 12 and Figure 13In one embodiment, the base 7013 may include a first base 7016 and a second base 7017. The first base 7016 is located below the second base 7017. A first feed assembly 703 is disposed between the first base 7016 and the frame 300. A tool mounting seat 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 lead screw seat 7043 is fixedly connected to the bottom of the second seat 7017. The second lead screw seat 7043 is sleeved on the second feed lead screw 7042 and is threadedly engaged with the second feed lead screw 7042. The fourth motor 7041 can drive the second feed lead screw 7042 to rotate. The threaded engagement between the second feed lead screw 7042 and the second lead screw seat 7043 can cause the second lead screw seat 7043 to move along the axial direction of the second feed lead screw 7042, thereby causing the second lead screw seat 7043 to drive the second seat 7017 to move in a direction perpendicular to the axis of the first feed lead screw 7032. With this configuration, before the first feed assembly 703 drives the grinding mount 7011 closer to the grinding station 302, the second feed assembly 704 first drives the second seat 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 closer to the grinding station 302. After the grinding mount 7011 is close to the grinding station 302, the second feed assembly 704 drives the second seat 7017 to move a certain distance closer to the grinding station 302, so that the grinding tool 7012 is close to the grinding station 302 and abuts against the part of the material to be ground (e.g., the surface of the armature commutator). This configuration avoids the possibility of the grinding tool 7012 colliding with the material due to the first feed assembly 703 directly feeding the grinding tool 7012, thus protecting both the grinding tool 7012 and the material. In other examples, the second feed component 704 can also be a cylinder or a hydraulic cylinder, which directly drives the second seat 7017 to move. Furthermore, to improve the moving stability of the second seat 7017, a guide rail pair is provided between the first seat 7016 and the second seat 7017. This application does not limit the number of guide rail pairs, as long as they can achieve stable movement of the second seat 7017.
[0080] See Figure 12 and Figure 13In one embodiment, the first drive assembly 702 includes a third drive member 7021, a first mounting base 7022, a first pulley group 7023, a first synchronous belt 7024, and a fourth drive member 7025. The third drive member 7021 is fixedly connected to the first mounting base 7022. The first pulley group 7023 includes multiple pulleys, which are rotatably connected to the first mounting base 7022. The first synchronous belt 7024 is wound around the multiple pulleys of the first pulley group 7023. The third drive member 7021 is a motor. The output shaft of the third drive member 7021 is coaxially fixed with any pulley in the first pulley group 7023. The third drive member 7021 can drive the first pulley group 7023 to rotate, thereby driving the first synchronous belt 7024 to rotate outside the first pulley group 7023. The fourth driving component 7025 is fixedly connected to the frame 300. The fourth driving component 7025 is a cylinder or hydraulic cylinder, and its output end can move in the height direction. The first mounting base 7022 is fixedly connected to the output end of the fourth driving component 7025. The first mounting base 7022 is located above the grinding station 302. When the output end of the fourth driving component 7025 moves to the lowest position, the first mounting base 7022 drives the first synchronous belt 7024 to press the material located on the grinding station 302. During the rotation of the first synchronous belt 7024, the friction force drives the material to rotate. During the rotation of the material, the grinding tool 7012 grinds the material.
[0081] 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 identical to the first drive assembly 702 in the above embodiments and will not be described again here. The grinding assembly 701 includes a swing cover 706, a swing shaft 707, a swing drive component 708, a rotation shaft 709, and a rotation drive component 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 through 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, integral 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 oscillating gear 7061 is generally fan-shaped, with its tooth surface located on the arc surface of the fan-shaped structure. The oscillating shaft 707 passes through both the oscillating cover 706 and the oscillating gear 7061. The rotation axis 7124 of the oscillating gear 7061 coincides with the axis of the oscillating shaft 707. Specifically, the rotation axis 7124 of the oscillating gear 7061 coincides with the center of the aforementioned fan-shaped structure. The oscillating shaft 707 is rotatably connected to the oscillating cover 706 and the oscillating gear 7061. Specifically, a second bearing 7072 is fixed on the oscillating shaft 707, and the oscillating shaft 707 is rotatably connected to the oscillating cover 706 and the oscillating gear 7061 through the second bearing 7072. 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 a clearance cavity 7062 inside. One end of the rotating shaft 709 passes through the swing cover 706 and enters the clearance cavity 7062, while the other end protrudes from the swing cover 706 and is exposed to the outside. A third bearing 7091 is fixed on the rotating shaft 709, and the rotating shaft 709 is rotatably connected to the swing cover 706 through the third bearing 7091. A grinding element 711 is fixed to the end of the rotating shaft 709 that protrudes from the swing cover 706. The grinding element 711 is used to grind the material, and the rotational path of the grinding element 711 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 within the clearance cavity 7062. The transmission assembly 712 includes, but is not limited to, a gear transmission assembly 712, a pulley transmission assembly 712, a sprocket transmission assembly 712, etc. For example, the transmission assembly 712 is a gear transmission assembly 712. A first gear 7121 is fixed on the shaft of the swing shaft 707 located within the clearance cavity 7062, and a second gear 7122 is fixed on the shaft of the rotation shaft 709 located within the clearance cavity 7062. A third gear 7123 is provided between the first gear 7121 and the second gear 7122. A rotating shaft 7124 is coaxially threaded through the third gear 7123, and the rotating shaft 7124 is fixedly connected to the third gear 7123. Both the 3rd gear and the rotating shaft 7124 are located in the clearance cavity 7062. The two ends of the rotating shaft 7124 are respectively fixed with the fourth bearing 7125. 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. With this setting, 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 detachably connected, including but not limited to snap-fit, magnetic attraction, bolt connection, buckle connection, etc. The swing drive 708 is a motor and is fixedly connected to the frame 300. A fourth gear 7081 is fixed on the output shaft of the swing drive 708. The fourth gear 7081 meshes with the tooth surface of the swing gear 7061. The swing drive 708 drives the swing gear 7061 to rotate around the swing shaft 707 through the meshing relationship between the fourth gear 7081 and the swing gear 7061. The self-rotation drive 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-rotation drive 710, and a sixth gear 7073 is fixed to the swing shaft 707. The fifth gear 7101 meshes with the sixth gear 7073. The self-rotation drive 710 drives the swing shaft 707 to rotate through the meshing relationship between the fifth gear 7101 and the sixth gear 7073. The swing shaft 707 then drives the self-rotation shaft 709 to rotate through the transmission of the first gear 7121, the third gear 7123 and the second gear 7122, thereby driving the grinding workpiece 711 to rotate.
[0082] When grinding is required, the oscillating drive 708 first drives the oscillating gear 7061 to rotate the oscillating cover 706 around the oscillating shaft 707. Since the oscillating gear 7061 and the fourth gear 7081 are meshed, the oscillating drive 708 can steplessly adjust the rotation angle of the oscillating cover 706. During the rotation of the oscillating cover 706 around the oscillating shaft 707, it drives the grinding piece 711 to move towards the grinding station 302. When the grinding piece 711 comes into contact with the material on the grinding station 302, the oscillating drive 708 stops driving the oscillating gear 7061. At this time, the rotation drive 710 starts to work. The rotation drive 710 drives the oscillating shaft 707 to rotate through the cooperation of the fifth gear 7101 and the sixth gear 7073. The oscillating shaft 707 then drives the rotation shaft 709 to rotate through the transmission of the first gear 7121, the third gear 7123 and the second gear 7122. The rotation of the spindle 709 drives the grinding element 711 to rotate, and the grinding element 711 grinds the material during rotation. Furthermore, to enhance the grinding effect, the rotation directions of the spindle drive 710 and the first drive assembly 702 can be preset so that the rotation direction of the grinding element 711 is opposite to the rotation direction of the material, thereby further improving the grinding effect. It should be noted that when the grinding element 711 is in contact with the material on the grinding station 302, it corresponds to the first position of the grinding mechanism 700; when the grinding element 711 is not in contact with the material on the grinding station 302, it corresponds to the second position of the grinding mechanism 700.
[0083] In addition to the functions mentioned above, the swing shaft 707 serves as both the swing center of the swing arm and the power transmission shaft of the self-rotating drive component 710. This arrangement can greatly reduce the space occupied by the grinding mechanism 700, and at the same time, it can fix the self-rotating drive component 710 on the frame 300. In this way, the self-rotating drive component 710 does not need to follow the movement of the swing cover 706, which reduces the possibility of damage to the cables on the self-rotating drive component 710 due to excessive movement and improves its service life.
[0084] In one embodiment, two sets of grinding mechanisms 700 are sequentially arranged along the conveying direction of the second conveyor line 600. Furthermore, the precision of the grinding tools 7012 in the two sets of grinding mechanisms 700 increases sequentially along the conveying direction of the second conveyor line 600. Correspondingly, two sets of grinding stations 302 are also provided, with each set of grinding stations 302 corresponding to one set of grinding mechanisms 700. This arrangement allows for rough grinding followed by fine grinding of the material. Rough grinding quickly removes most of the excess material from the workpiece surface, shortening the grinding time, while fine grinding improves the precision and surface finish of the ground areas.
[0085] See Figure 12 and Figure 15In one embodiment, a dust collection hood 705 is provided near the grinding station 302. The dust collection hood 705 has a suction chamber 7051, which is connected to an external vacuum cleaner via a flexible hose. The grinding station 302 is at least partially located within the suction chamber 7051. The suction chamber 7051 generates negative pressure under the drive of the vacuum cleaner to absorb the debris generated when the grinding mechanism 700 grinds the material. With this configuration, the vacuum cleaner can absorb the debris generated during the grinding process, thus avoiding environmental pollution.
[0086] See Figure 15 In one embodiment, the dust collection hood 705 includes an upper hood 7052 and a lower hood 7053. The lower hood 7053 is fixedly connected to the frame 300, and the upper hood 7052 is connected to the first mounting base 7022. When the output end of the fourth driving member 7025 moves to the lowest position, the first mounting base 7022 drives the upper hood 7052 to press against the lower hood 7053 to form a dust suction chamber 7051. This arrangement prevents the upper hood 7052 from affecting the material transport on the transport path of the second conveyor line 600, allowing the material to be smoothly placed on the grinding station 302. In addition, the dust collection hood 705 has a clearance groove 7054 on the side facing the grinding tool 7012, allowing the grinding tool 7012 to move to the first position through the clearance groove 7054.
[0087] See Figure 2 and Figure 12 In one embodiment, the frame 300 is further provided with a burr removal station 304, which is located between the grinding station 302 and the second inspection station 303. It should be noted that the burr removal station 304 and the grinding station 302 have the same structure, differing only in their fixed positions on the frame 300. The structure of the burr removal station 304 is similar to that of the grinding station 302 and will not be described again here. Furthermore, the transport rod 601 also passes between the two second support seats 3021 of the burr removal station 304. The process of transporting material from the grinding station 302 to the burr removal station 304 is the same as the process of transporting material from the placement station 607 to the grinding station 302, and will not be described again here. The armature commutator downstream production line also includes a burr removal mechanism 800, which is located between the grinding mechanism 700 and the second inspection mechanism 900. After the material is coarsely and finely ground by the grinding mechanism 700, the ground parts of the material may have a small amount of burrs (such as small particles). The purpose of the burr removal mechanism 800 is to remove the burrs from the material located at the burr removal station 304.
[0088] See Figure 12In one embodiment, the deburring 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, and 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. This arrangement ensures that the rotation of the material and the rotation of the brush are synchronized, improving the deburring effect.
[0089] See Figure 12 In one embodiment, to improve deburring efficiency, the deburring station 304 is provided with two sets. The fifth drive unit 8011 is a dual-axis motor, and an extension shaft 8013 is coaxially fixed on each output shaft of the fifth drive unit 8011. One deburring component 8012 is fixedly connected to the end of each extension shaft 8013 away from the fifth drive unit 8011. The deburring components 8012 on the two extension shafts 8013 correspond one-to-one with the two deburring stations. In this way, the fifth drive unit 8011 can drive the two deburring components 8012 to rotate simultaneously, and the two deburring components 8012 can simultaneously deburr the materials at the two deburring stations, thereby improving the deburring efficiency.
[0090] See Figure 12In one embodiment, the second drive assembly 802 includes a second mounting base 8021, a sixth drive member 8022, a second pulley group 8023, a second synchronous belt 8024, and a seventh drive member 8025. The second pulley group 8023 includes multiple pulleys, each rotatably connected to the second mounting base 8021. The second synchronous belt 8024 is wound around the multiple pulleys of the second pulley group 8023. The sixth drive member 8022 is a motor, fixedly connected to the second mounting base 8021. The output shaft of the sixth drive member 8022 is coaxially fixed with any pulley in the second pulley group 8023, and the sixth drive member 8022 can drive the second synchronous belt 8024 to rotate. The seventh drive component 8025 is fixedly connected to the frame 300. The seventh drive component 8025 is a cylinder or hydraulic cylinder, and its output end can move vertically. The second mounting base 8021 is fixedly connected to the output end of the seventh drive component 8025 and is located above the deburring station. When the output end of the seventh drive component 8025 moves to its lowest position, the second mounting base 8021 drives the second synchronous belt 8024 to press the material located at the deburring station 304. During its rotational motion, the second synchronous belt 8024 drives the material to rotate through friction. Furthermore, when the second synchronous belt 8024 presses the material at the deburring station 304, the deburring component 8012 simultaneously contacts the part of the material on the deburring station 304 where the burrs to be removed.
[0091] See Figure 2 and Figure 16 In one embodiment, the armature commutator downstream production line further includes a second detection mechanism 900, which includes a sensor system 901. The sensor system 901 is used to identify image information and / or three-dimensional information of the material placed on the second detection station 303. It should be noted that image information refers to an image containing the material, and three-dimensional information refers to the three-dimensional coordinate information of the material surface. Specifically, the memory 202 of the control system 200 pre-stores images of the material after grinding and / or the three-dimensional coordinate information of the material after grinding. After the sensor system 901 identifies the image information and / or three-dimensional information of the material, it compares it with the pre-stored images and / or three-dimensional coordinate information 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.
[0092] See Figure 16In one embodiment, the second detection mechanism 900 further includes a third drive assembly 902, which includes a third mounting base 9021, an eighth drive member 9022, a third pulley group 9023, a third synchronous belt 9024, and a ninth drive member 9025. The third pulley group 9023 includes multiple pulleys, each rotatably connected to the third mounting base 9021. The third synchronous belt 9024 is wound around the multiple pulleys of the third pulley group 9023. The eighth drive member 9022 is a motor, fixedly connected to the third mounting base 9021. The output shaft of the eighth drive member 9022 is coaxially fixed with any pulley in the third pulley group 9023, and the eighth drive member 9022 can drive the second synchronous belt 8024 to rotate. The ninth driving component 9025 is fixedly connected to the frame 300. The ninth driving component 9025 is a cylinder or hydraulic cylinder, and its output end can move in the vertical direction. The third mounting base 9021 is fixedly connected to the output end of the ninth driving component 9025 and is located above the second detection station 303. When the output end of the ninth driving component 9025 moves to its lowest position, the third mounting base 9021 drives the third synchronous belt 9024 to press the material located on the second detection station 303. During the rotation of the third synchronous belt 9024, the friction force drives the material to rotate. 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 this application is used to identify the image information of the material placed on the second detection station 303. Correspondingly, the memory 202 of the control system 200 pre-stores images of the material after grinding. With this setup, image information can be acquired during the rotation of the material, enabling 360° omnidirectional identification of the material, thereby improving the identification accuracy.
[0093] See Figure 16In one embodiment, the second detection mechanism 900 further includes a gripping component 903, which includes a fourth conveyor line 9031, a tenth drive member 9032, and a gripping element 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 being their installation position and transport direction, which will not be described in detail here. The tenth drive member 9032 is fixedly connected to the synchronous belt 403 of the fourth conveyor line 9031. The connection method between the tenth drive member 9032 and the fourth conveyor line 9031 is the same as the connection method between the first drive member 5013 and the third conveyor line 5011, which will not be described in detail here. The tenth driving component 9032 is a cylinder or hydraulic cylinder, capable of moving in the vertical direction. A fourth extension plate 9034 is fixedly connected to the output end of the tenth driving component 9032. A gripping component 9033 is fixedly connected to the fourth extension plate 9034 and to the output end of the tenth driving component 9032 via the fourth extension plate 9034. A second electromagnet 9035 is connected to the gripping component 9033, used to grip the material on the second detection station 303. The second electromagnet 9035 is electrically connected to the control system 200, which can control the on / off state of the second electromagnet 9035. It should be noted that the process of the gripping component 903 gripping the material is the same as the process of the first gripping arm 5012 picking up the material, and will not be described again here. After the sensor system 901 completes the identification of the material, when the material meets the requirements, the gripping component 903 grips the material and places it in the qualified product placement area; when the material does not meet the requirements, the gripping component 903 grips the material and places it in the unqualified product placement area. Additionally, when the conductivity test result of the material at the first inspection station is unqualified, the material is recorded by the control system 200 and transported by the second conveyor line 600 to the second inspection station 303, where the gripping component 903 grips the unqualified material and places it in the unqualified product placement area. In other embodiments, another unqualified placement area can be set near the third conveyor line 5011, and a fourth stopping point can be set on the second conveyor line 600, 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 gripping arm 5012 directly picks up the material and places it in the unqualified placement area near the third conveyor line 5011.
[0094] See Figure 16In one embodiment, the third drive assembly 902 further includes an eleventh drive member 9026, which is a cylinder 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 moving in the horizontal direction. The third mounting base 9021 is fixedly connected to the output end of the tenth drive member 9032. Before the gripping member 9033 grips the material on the second detection station 303 using the second electromagnet 9035, the eleventh drive member 9026 moves the third mounting base 9021 away from the material on the second detection station 303 to fully expose the material, so that the second electromagnet 9035 can grip the material.
[0095] It should be noted that the materials in this application require multiple positioning checks when on the first inspection station 301, placement station 607, temporary station 606, grinding station 302, and second inspection station 303, as well as during the material transfer process. To achieve automatic positioning, position sensors are also installed at corresponding positions on the production line after the armature commutator. The photoelectric sensor 5017 installed at the position where the first gripping arm 5012 grips the material on the first conveyor line 400 is also a position sensor. Position sensors include, but are not limited to, DToF sensors, IToF sensors, lidar, line laser sensors, monocular cameras, multi-view cameras, ultrasonic sensors, Hall effect sensors, etc. The working principle of position sensors is prior art, and those skilled in the art can set position sensors at the corresponding positions as needed. This application will not elaborate on them one by one.
[0096] In this 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 from 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 paths of the first conveyor line 400 and the second conveyor line 600 can realize the automated conveying of the material through 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 armature conductivity detection and armature commutator surface grinding can be fully automated, improving the production efficiency of the armature.
[0097] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
