[0002] With the rapid development of the new energy vehicle industry, the performance and reliability of the motor as one of its core components have received increasing attention. Among the motors of new energy vehicles, permanent magnet synchronous motors have become the mainstream choice due to their advantages such as high power density, high efficiency, small size and low noise. The rotor surface magnetic detection of permanent magnet synchronous motors is a key link to ensure their performance and reliability. At present, the rotor surface magnetic detection of permanent magnet synchronous motors mainly adopts manual detection, which usually takes a lot of time and human resources, resulting in low detection efficiency. With the development of Industry 4.0 and intelligent manufacturing, manual detection methods are difficult to seamlessly connect with automated production lines and intelligent detection systems, which limits the optimization and upgrading of production processes.

DETAILED DESCRIPTION

[0028] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Reference Figures 1 to 9 As shown, the present invention provides a fully automatic surface magnetism detection machine for a motor rotor. In one embodiment, it includes a product transmission line 1; a transfer device 2 and a pressing device 3 are also arranged on one side of the product transmission line 1; a surface magnetism detection device 4 and a rotating device 5 are also arranged between the transfer device 2 and the pressing device 3; the rotating device 5 is located below the pressing device 3; the transfer device 2 is used to transfer the product transmitted by the product transmission line 1 to the rotating device 5; the pressing device 3 is used to press and limit the product located on the rotating device 5, and the rotating device 5 is used to drive the product to rotate; the surface magnetism detection device 4 is used to detect the surface magnetic field of the product, and the transfer device 2 is also used to move the product after the detection back to the product transmission line 1.

[0030] Continue to refer to Figures 1 to 9 As shown, in this embodiment, a workbench 6 is also included, and the transfer device 2, the pressing device 3, the surface magnetic detection device 4 and the rotating device 5 are all installed on the workbench 6, and an organic shell ( Figure 1 The casing wraps the above-mentioned mechanism inside, and openings are provided at both ends of the casing. The product transmission line 1 is arranged through the casing through the openings. At the same time, a control screen is installed on the front of the casing, an indicator light is installed on the top of the casing, and a foot pad and a foot cup are installed on the bottom of the casing.

[0031] In this embodiment, a lifting device and a stopping mechanism are also arranged in the product transmission line 1; the product transmission line 1 includes a transmission frame arranged transversely through the casing, a transmission track is installed on each of the two sides of the top of the transmission frame, and a transmission chain module is also installed on the transmission track; a transmission drive mechanism is installed on one side of one of the transmission tracks, and the transmission drive mechanism is connected to the transmission chain module; the transmission drive mechanism is used to drive the transmission chain module to operate so as to transmit the pallet carrying the product; the lifting device is arranged between the two transmission frames, and the lifting device includes a lifting fixed plate, a first lifting drive module, and a first lifting plate; the lifting fixed plate is arranged between the two transmission tracks, and a plurality of first lifting guide rods are also installed on the lifting fixed plate; the first lifting drive module is installed on the lifting fixed plate, and the first lifting plate is installed on the first lifting guide rod and connected to the first lifting drive module; a first supporting pad is installed at each of the four corners of the top of the first lifting plate, and the tops of the two first supporting pads are respectively installed with a first cylindrical pin and a first diamond pin.

[0032] The first lifting drive module adopts a lifting cylinder, which can drive the first lifting plate to rise and fall to lift the pallet. At the same time, two first supporting pads located at one of the diagonals on the top of the first lifting plate are respectively installed with a first cylindrical pin and a first diamond pin, which can be used in conjunction with the corresponding sockets on the bottom of the pallet to ensure the stability of the pallet during lifting, so that the transfer device 2 can transfer the product from the pallet to the rotating device 5. At the same time, the stopping mechanism is installed on the transmission track and arranged close to the lifting device. The stopping mechanism includes a stopping cylinder and a block connected to the stopping cylinder. When the transmission chain module transfers the pallet to the preset lifting position (i.e., the lifting device), the stopping cylinder drives the block to rise to stop the pallet, so that the lifting device can lift the pallet.

[0033] During operation, a manual or external manipulator places a pallet carrying a product (in this embodiment, a motor rotor) on the product transmission line 1, and the product transmission line 1 transmits the pallet to the lifting device; then, the stopping mechanism stops the pallet, and the lifting device lifts and separates the pallet from the product transmission line 1; then, the transfer device 2 transfers the product to the rotating device 5, and the pressing device 3 presses and limits the product on the rotating device 5; then, the surface magnetic detection device 4 moves to the product, the rotating device 5 drives the product to rotate, and the surface magnetic detection device 4 detects the surface magnetic field of the product. After the detection, the transfer device 2 moves the detected product back to the pallet; then, the lifting device descends to put the pallet back on the product transmission line 1, the stopping mechanism descends, and the product transmission line 1 transmits the pallet to the next process. In this embodiment, the detection machine realizes a series of processes such as automatic loading, surface magnetic detection and unloading of the motor rotor, with a high degree of automation, which reduces the steps of manual operation, significantly improves the efficiency of motor rotor surface magnetic detection, shortens the detection time, and meets the needs of large-scale production.

[0034] In one embodiment, the rotating device 5 includes a first mounting plate 51, a hollow rotating platform 52, a rotating drive assembly 53, a fixture seat, and a positioning pin assembly 55; the hollow rotating platform 52 is mounted on the first mounting plate 51, and the fixture seat is mounted on the hollow rotating platform 52; the positioning pin assembly 55 is installed in the fixture seat, and one end of the positioning pin assembly 55 passes through the top of the fixture seat and extends outward; the rotating drive assembly 53 is installed at the bottom of the first mounting plate 51 and is connected to the hollow rotating platform 52. The first mounting plate 51 is installed on the workbench 6, and the rotating drive assembly 53 includes a rotating motor and a reducer, which can drive the hollow rotating platform 52 to drive the fixture seat to rotate; the product transferred by the transfer device 2 is placed on the fixture seat, and the product is limited by the positioning pin assembly 55, and the product can rotate with the fixture seat, so as to facilitate the surface magnetic detection device 4 to detect the surface magnetic field of the product.

[0035] At the same time, the positioning pin assembly 55 includes a first fixed seat 551, a detection rod 552, a positioning connection block 553, two positioning pins 554, and a first spring 555; the upper part of the first fixed seat 551 is installed in the fixture seat, and the lower part of the first fixed seat 551 passes through the hollow rotating platform 52 and extends to the lower direction of the first mounting plate 51; the first fixed seat 551 is also installed with a first bushing 556, and the detection rod 552 is arranged in the first fixed seat 551 and moves through the first bushing 556. The top of the detection rod 552 is also connected to a bearing truncated platform 557, and the positioning connection block 553 is installed on the bearing truncated platform 557; the two positioning pins 554 are respectively installed at one end of the top of the positioning connection block 553, and the upper part of each positioning pin 554 is movable through the fixture seat and then passes through the top of the fixture seat and extends outward; the first spring 555 is sleeved on the outer wall of the detection rod 552, and the two ends of the first spring 555 are respectively abutted against the bottom of the bearing truncated platform 557 and the top of the first bushing 556.

[0036] The detection rod 552 can slide up and down in the first fixed seat 551 relative to the first bushing 556. When the transfer device 2 transfers the product to the fixture seat, it is necessary to first perform a pin-finding and positioning action, because at this time the positioning hole at the bottom of the product may not be aligned with the positioning pin 554, which will then generate downward pressure on the positioning pin 554, causing the positioning pin 554 to move downward. When the positioning pin 554 moves downward, a downward force is applied to the bearing round table 557 through the positioning connecting block 553, causing the detection rod 552 to move downward. When the detection rod 552 moves downward, an extrusion force is generated on the first spring 555, causing the first spring 555 to be in a In the compressed state, under the influence of the restoring force of the first spring 555, the detection rod 552 will generate a continuous upward restoring force on the positioning pin 554 through the bearing truncated table 557. At this time, the hollow rotating platform 52 will drive the fixture seat to rotate to adjust the position of the positioning pin 554 until the positioning pin 554 is aligned with the positioning hole at the bottom of the product. The positioning pin 554 is driven by the restoring force of the first spring 555 to move upward and then inserted into the positioning hole to complete the product positioning. In this embodiment, the positioning pin 554 is first lowered and then raised to find the pin, so that the product can be quickly positioned. At the same time, this flexible pin finding method can prevent the pin from scratching the product.

[0037] At the same time, the bottom of the first mounting plate 51 is also connected to the first support frame 511, and the bottom of the first support frame 511 is also installed with an encoder 512; a universal coupling 513 is also installed on the output shaft of the encoder 512, and the top of the universal coupling 513 is connected to the bottom of the first fixed seat 551. The upper part of the first fixed seat 551 is installed in the fixture seat. When the fixture seat rotates with the hollow rotating platform 52, it can drive the first fixed seat 551 to rotate, and the bottom of the first fixed seat 551 is connected to the encoder 512 via the universal coupling 513, so the encoder 512 can detect the rotation state of the first fixed seat 551 and the fixture seat in real time, which is convenient for the background closed-loop control of the fixture seat rotation and improve its rotation accuracy; at the same time, the lower part of the detection rod 552 is also connected to the first latch, and at least two first sliding holes 514 are spaced apart on the circumference of the lower part of the outer wall of the first fixed seat 551; A sliding hole 514 is opened along the axial direction of the first fixed seat 551, and the two ends of the first pin are movably arranged through the first sliding hole 514 respectively; the lower part of the outer wall of the first fixed seat 551 is also movably sleeved with a first induction ring 515, and the inner wall of the first induction ring 515 is connected to the end of the first pin that movably passes through the first sliding hole 514; a first proximity switch 516 is installed on each side of the first support frame 511, and one of the first proximity switches 516 is arranged near the top of the first induction ring 515, and the other first proximity switch 516 is arranged near the bottom of the first induction ring 515. When performing the above-mentioned pin finding action, the detection rod 552 will move downward, and the detection rod 552 is connected to the first induction ring 515 via the first pin, so it can drive the first induction ring 515 to descend synchronously. Since a first proximity switch 516 is installed on each side of the first support frame 511, and one of the first proximity switches 516 is arranged close to the top of the first induction ring 515, and the other first proximity switch 516 is arranged close to the bottom of the first induction ring 515, the position of the first induction ring 515 can be detected by the two first proximity switches 516, so that the background can obtain the descending stroke and position of the detection rod 552, which is convenient for accurately controlling the pin finding action.

[0039] During the pin-finding action, the positioning pin 554 will move up and down along the first socket and the second socket. At the same time, the positioning connection block 553 can move up and down along the guide channel, which can not only improve the compactness of the structure, but also guide its lifting and lowering, thereby improving its lifting and lowering stability. At the same time, in order to guide the lifting and lowering of the positioning pin 554, in this embodiment, the outer wall of the upper rotating seat 57 is also provided with a guide slide hole 503 along its axial direction, and each side of the positioning pin 554 is also connected to a guide pin 54; each guide pin 54 is correspondingly and movably inserted in a guide slide hole 503.

[0042] In this embodiment, the lower part of the contoured pressing member 346 is conical in structure, which matches the corresponding hole position on the top of the product. When the product is placed on the fixture seat, the contoured pressing member 346 is driven by the pressing driving mechanism 35 to press the product down. Subsequently, the rotating device 5 drives the fixture seat to drive the product to rotate. During the rotation of the product, since the product and the contoured pressing member 346 will contact, friction may be generated between the two, and then the contoured pressing member 346 may be driven to rotate by the friction. At this time, the pressing cylinder 302 will drive the pressing friction plate 303 to descend, so that it contacts the first friction block 301, and friction is generated between the two, which can prevent the first connecting rod 343 from rotating. The bottom of the first connecting rod 343 is connected to the pressing connecting seat 345, and the contoured pressing member 346 is installed on the pressing connecting seat 345, so it can generate resistance to the contoured pressing member 346 to prevent it from rotating with the product, thereby avoiding affecting the accuracy of product surface magnetic detection.

At the same time, when the surface magnetic detection probe 443 is away from the product, it can be driven by the restoring force of the second spring 445 to quickly reset.
