Description

Technical Field

[0001] The present invention relates to the technical field of motor component assembly, and more particularly, to a precision assembly robot for motor components. Background Art

[0002] A precision assembly robot for motor components is a mechanical device used for assembling motor spare parts of new energy vehicles, which can attach magnet spare parts to the rotor of a new energy vehicle motor. It is widely used in the manufacture of permanent magnet synchronous motors, brushless DC motors, and servo motors for new energy vehicles. The quality of magnet mounting directly affects the performance, efficiency, and reliability of the motor when used in new energy vehicles.

[0003] Traditional magnet - attaching equipment directly pushes magnet spare parts into the fitting frame on the outer ring surface of the motor rotor. It not only lacks lateral restraint but also relies on the initial alignment accuracy. If the initial alignment accuracy is low, the magnet is likely to shift horizontally during the pushing process, resulting in the magnet being skewed, and thus the consistency of the attached magnets is poor.

[0004] At the same time, traditional magnet - attaching equipment usually has a single - row magnet - attaching design, and a set of fixed production equipment is designed for each size of the motor rotor. This makes the change in the number of attached magnets and the change in rotor size lead to equipment replacement or large - scale adjustment, resulting in cumbersome and time - consuming operation steps and reducing the efficiency of magnet attachment.

[0005] To solve the above problems, the inventor has proposed a precision assembly robot for motor components. Summary of the Invention

A trapezoidal block is slidably connected to each two grooves together. A plurality of fixing seats are annularly and equidistantly inserted into the clamping plate. Two reset springs are symmetrically and fixedly connected to each fixing seat.

[0010] Preferably, the tray is fixedly connected to the lower robotic arm. A plurality of first slots are symmetrically formed on the tray. The number of the first slots is equal to the number of the first inserting blocks. Each first slot is in interference fit with the corresponding first inserting block.

[0014] Preferably, a driving component is provided on the upper robotic arm. The driving component includes a connecting plate and a clamping ring. A plurality of second inserting blocks are symmetrically and fixedly connected to the bottom of the connecting plate. An electric telescopic rod one is fixedly installed at the bottom of the connecting plate. A plurality of third slots are annularly and equidistantly formed at the bottom of the clamping ring.

[0015] Preferably, the connecting plate is fixedly connected to the upper robotic arm. A vacuum chuck is provided at the telescopic end of the electric telescopic rod one, and a motor rotor is adsorbed by the vacuum chuck.

[0016] Preferably, a plurality of second slots are symmetrically formed on the clamping ring. The number of the second slots is equal to that of the second insertion blocks.

[0018] As described above, the advantages of the present invention are as follows:

[0019] In the fitting assembly of the present device, the center line of the outer ring surface fitting frame of the motor rotor is automatically aligned by inserting the frame body into the outer ring surface fitting frame of the motor rotor, so as to realize the correction before fitting the magnet. Due to the constraint of the frame body, the fitted magnet will not shift or skew, solving the problem that in the traditional magnetic pasting equipment, the magnet is directly pushed into the outer ring surface fitting frame of the motor rotor, lacking lateral constraint and resulting in easy lateral movement of the magnet during the pushing process. In this way, the mounting accuracy and operation stability of the industrial robot are improved, and the stability of the new energy vehicle motor during use is also increased.

[0020] The magnetic pasting assembly and the limiting assembly in the present device cooperate with each other. The motor rotor is moved upward by the hydraulic equipment, so as to meet the fitting requirements of multiple magnets, solving the problem that the traditional magnetic pasting equipment is usually designed with a single magnetic pasting row number. When the row number needs to be switched, the whole set of equipment needs to be replaced, resulting in low fitting efficiency. In this way, the model change speed of the industrial robot is improved, and it can adapt to the assembly work of different new energy vehicle motors. One set of equipment can cover multiple magnetic row arrangement schemes, improving the adaptability of the industrial robot.

[0021] The magnetic pasting assembly, the limiting assembly and the driving assembly in the present device are modularly designed and can be replaced, so as to adapt to the motor rotors with different numbers of fitting frames. On the basis of correcting the fitting accuracy of the magnet, the fitting requirements of the magnet for the outer ring surface fitting frame of the motor rotor with an odd or even number are further realized, solving the problem that in the traditional magnetic pasting equipment, a set of fixed production equipment needs to be designed for each size of the motor rotor. When the number of the rotor fitting frames changes, it will lead to the replacement or large-scale adjustment of the equipment, resulting in complicated operation steps. In this way, the diversified production requirements are met. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0040] The embodiments provided by the present invention will be elaborated in detail below:

[0041] A precision assembly robot for motor components, as Figure 1 and Figure 2 shown, includes a robot main body 1. A placement rack 11 is fixedly connected to the outer wall of the robot main body 1. Two robotic arms 2 are symmetrically and vertically slidably connected to one side of the robot main body 1 away from the placement rack 11;

[0042] As Figures 2 to 7 shown, a magnetic pasting component is provided on the lower robotic arm 2. The magnetic pasting component includes a tray 31 and a clamping plate 32. A plurality of first inserting blocks 33 are symmetrically and fixedly connected to the bottom surface of the clamping plate 32. A plurality of sliding grooves 34 are annularly and equally spaced on one side of the clamping plate 32 away from the first inserting blocks 33. A sliding block 35 is slidably connected to each of the plurality of sliding grooves 34. A placement frame 36 is inserted on one side of each sliding block 35 away from the sliding groove 34. A baffle 37 and a fixing plate 38 are fixedly connected to the inner cavity wall of each placement frame 36. A connecting spring 39 is fixedly connected to one side of each fixing plate 38 close to the baffle 37. A pushing plate 310 is fixedly connected to one side of each connecting spring 39 away from the adjacent fixing plate 38. The pushing plate 310 is located directly below the baffle 37. Two grooves 311 are formed in the inner cavity wall of each placement frame 36, and the two grooves 311 are symmetrically arranged. A trapezoidal block 312 is vertically slidably connected to each pair of grooves 311. The trapezoidal block 312 is located on the side close to the fixing plate 38. A plurality of fixing seats 313 are annularly and equally spaced and inserted on the clamping plate 32, and the plurality of fixing seats 313 are located on the side away from the center of the clamping plate 32. Two reset springs 314 are symmetrically and fixedly connected to each fixing seat 313.

[0043] Furthermore, as Figures 2 to 4 shown, the tray 31 is fixedly connected to the lower robotic arm 2. A plurality of first slots are symmetrically formed in the tray 31. The number of the first slots is equal to the number of the first inserting blocks 33. Each first slot is in interference fit with the corresponding first inserting block 33, and the first inserting blocks 33 are all located inside the first slots.

[0044] Furthermore, as Figures 4 to 6As shown, each push plate 310 is horizontally and slidably connected to the adjacent placement frame 36. The number of fixed seats 313 is equal to the number of sliders 35. The ends of every two reset springs 314 away from the fixed seats 313 are fixedly connected to the sliders 35 together.

[0045] Further, as Figure 5 , Figure 8 and Figure 9 shown, a limiting component is arranged on each placement frame 36. The limiting component includes a slide rail 41 and a fixed block 42 fixedly connected to the outer wall of each placement frame 36. The slide rail 41 and the fixed block 42 are located on the same side. A rack 43 is horizontally and slidably connected to each slide rail 41. One end of each rack 43 close to the adjacent fixed block 42 is fixedly connected to a first spring 44. A nut 45 is rotatably connected to the outer side wall of each placement frame 36. Each nut 45 is fixedly connected to a gear 46. Each nut 45 is threadedly connected to a lead screw 47. The part of the lead screw 47 away from the gear 46 is located inside the placement frame 36, and the length of the part of the lead screw 47 located inside the placement frame 36 does not exceed half of the width of the placement frame 36, so as to facilitate limiting the non-fitting magnets in the placement frame 36. The lead screw 47 is in contact with the push plate 310, and the lead screw 47 and the nut 45 form a ball screw structure.

[0046] Further, as Figure 5 shown, one end of each first spring 44 away from the adjacent rack 43 is fixedly connected to the adjacent fixed block 42. Each gear 46 is meshed with the adjacent rack 43.

[0047] Further, as Figure 2 , Figure 10 and Figure 11 shown, a driving component is arranged on the upper robotic arm 2. The driving component includes a connecting plate 51 and a clamping ring 52. A plurality of second inserts 53 are fixedly connected to the bottom surface of the connecting plate 51 at equal intervals in a ring shape. An electric telescopic rod one 54 is fixedly installed at the bottom of the connecting plate 51. A plurality of slots three are formed in the bottom of the clamping ring 52 at equal intervals in a ring shape. A pressing rod 55 is inserted into the plurality of slots three. A connecting disk 57 is fixedly connected to the bottom of the connecting plate 51. A plurality of support rods 58 are fixedly connected to the bottom of the connecting disk 57.

[0048] Further, as Figure 10 shown, the connecting plate 51 is fixedly connected to the upper robotic arm 2. A vacuum chuck is arranged on the electric telescopic rod one 54. The vacuum chuck is externally connected and controlled by a vacuum generator, and the vacuum chuck adsorbs a motor rotor. A plurality of fitting frames are fixedly arranged on the outer ring surface of the motor rotor at equal intervals in a ring shape. Glue is coated on the inner wall of the fitting frame, which is used for fitting magnets, and the motor rotor is an existing device and will not be elaborated here.

[0049] Further, asFigure 10 As shown, a plurality of second slots are symmetrically formed in the snap ring 52. The number of the second slots is equal to the number of the second insertion blocks 53. Each second slot is in interference fit with the corresponding second insertion block 53. The number of the pressing rods 55 is equal to the number of the trapezoidal blocks 312, and the pressing rods 55 correspond to the trapezoidal blocks 312.

[0050] Further, as Figure 1 shown, another set of magnetic sticker components, limiting components and driving components are further arranged on the placing rack 11, and the another set of magnetic sticker components, limiting components and driving components can be replaced with the magnetic sticker components, limiting components and driving components on the robotic arm 2, so as to adapt to motor rotors with different diameters. Among them, the number of the sliding grooves 34 in the magnetic sticker component on the lower robotic arm 2 is an even number, the number of the pressing rods 55 in the driving component on the upper robotic arm 2 is an even number, and the number of the sliding grooves 34 in the magnetic sticker component on the placing rack 11 and the number of the pressing rods 55 in the driving component are odd numbers, so as to adapt to different numbers of fitting frames on the outer ring surface of different motor rotors.

[0051] During operation:

[0052] If only one magnet needs to be attached to each fitting frame on the outer ring surface of the motor rotor, the device can perform the magnetic sticker work. The following are the detailed steps:

[0053] The staff places the motor rotor below the vacuum chuck on the electric telescopic rod 54, and then starts the vacuum chuck through the controller, so that the vacuum chuck fixes the motor rotor, and the fitting frames on the outer ring surface of the motor rotor correspond to the adjacent placing frames 36 one by one. After the motor rotor is fixed, the staff removes the trapezoidal block 312 and pulls the push plate 310, so that the push plate 310 moves towards the side close to the fixing plate 38 and compresses the connecting spring 39. Then, the magnets to be attached are loaded into the placing frame 36. Here, it should be noted that the magnets are stacked and attached to each other magnetically after production, and there is no need for manual stacking to adapt to the inside of the placing frame 36. Therefore, reference can be made to the appendix Figure 12 , after loading the magnets, release the hand, so that the push plate 310 moves towards the side away from the fixing plate 38 under the reset of the connecting spring 39. When the push plate 310 stops, the first magnet among all the magnets in the placing frame 36 contacts the lead screw 47, and the last magnet among all the magnets in the placing frame 36 contacts the push plate 310;

[0054] After the magnets are loaded, the staff inserts the trapezoidal block 312 back into the groove 311 on the inner cavity wall of the placement frame 36, so that the trapezoidal block 312 is in its initial position. Then, through the controller, the telescopic end of the second electric telescopic rod 56 moves vertically downward, driving the connection plate 57 and the support rod 58 to move vertically downward together until the distance between the bottom of the support rod 58 and the bottom of the fitting groove on the outer ring surface of the motor rotor is equal to the height of one magnet. At this time, the telescopic end of the second electric telescopic rod 56 stops moving. Then, the staff makes the upper robotic arm 2 move vertically downward through the controller. The vertical downward movement of the upper robotic arm 2 drives the motor rotor and the clamping ring 52 to move vertically downward together;

[0055] During the vertical downward movement of the clamping ring 52, the pressing rod 55 on the bottom surface of the clamping ring 52 first contacts the inclined surface of the trapezoidal block 312. As the clamping ring 52 continues to move vertically downward, the pressing rod 55 on the bottom surface of the clamping ring 52 presses the trapezoidal block 312, causing the trapezoidal block 312 to drive the placement frame 36 and the slider 35 to move along the sliding groove 34 in the direction away from the fixed seat 313, that is, the placement frame 36 moves in the direction closer to the motor rotor. When the pressing rod 55 no longer contacts the inclined surface of the trapezoidal block 312, that is, when the outer wall of the pressing rod 55 contacts the vertical surface of the trapezoidal block 312, the placement frame 36 and the slider 35 stop moving. And because the slider 35 moves in the direction away from the fixed seat 313, the return spring 314 is stretched by the slider 35 and is in an extended state;

[0056] During the movement of the placement frame 36 in the direction closer to the motor rotor, the rack 43 on the outer wall of the placement frame 36 first contacts the fitting frame on the outer ring surface of the motor rotor. At this time, the placement frame 36 continues to move, and the stationary fitting frame pushes the rack 43 due to the movement of the placement frame 36, causing the rack 43 to move along the slide rail 41 in the direction closer to the fixed block 42. And because the rack 43 moves in the direction closer to the fixed block 42, the first spring 44 is compressed by the rack 43 and is in a compressed state;

[0057] During the movement of the rack 43 towards the side close to the fixed block 42, the driving gear 46 rotates clockwise. The clockwise rotating gear 46 drives the nut 45 to rotate together, causing the lead screw 47 to gradually move away from the push plate 310 and away from the placement frame 36. When the lead screw 47 is no longer located in the inner cavity of the placement frame 36, the lead screw 47 no longer limits the first magnet. At this time, a part of the placement frame 36 has been inserted into the fitting frame on the outer ring surface of the motor rotor. Then, under the reset of the connecting spring 39, the first magnet is pushed into the inner cavity wall of the fitting frame on the outer ring surface of the motor rotor, and the magnet contacts the glue in the fitting frame, thus realizing the fixation of the magnet. At this time, the requirement of fitting only one magnet in each fitting frame on the outer ring surface of the motor rotor is completed. After the requirement of fitting only one magnet is completed, the staff makes the upper robotic arm 2 move vertically upward to the initial position through the controller, and makes the telescopic end of the second electric telescopic rod 56 contract through the controller, driving the support rod 58 back to the initial position. After both the upper robotic arm 2 and the second electric telescopic rod 56 return to the initial position, the staff can remove the motor rotor with the magnet fitted;

[0058] In the above process, the fitting component in this device automatically aligns the center line of the fitting frame on the outer ring surface of the motor rotor by inserting the frame body into the fitting frame on the outer ring surface of the motor rotor, thus realizing the correction before fitting the magnet. Through the restraint of the frame body, the fitted magnet will not shift or skew, solving the problem that the traditional magnet - sticking equipment directly pushes the magnet into the fitting frame on the outer ring surface of the motor rotor, lacking lateral restraint, resulting in the magnet being prone to lateral movement during the pushing process. In this way, the mounting accuracy and operation stability of the industrial robot are improved, and the stability of the new - energy vehicle motor during use is also enhanced.

[0059] If multiple magnets need to be fitted in each fitting frame on the outer ring surface of the motor rotor, this device can also perform the magnet - sticking work. The following are the detailed steps:

[0060] After the first magnet is attached, the worker uses the controller to extend the electric telescopic rod 54, driving the motor rotor to move vertically downward. The extension distance is the height of one magnet. After the electric telescopic rod 54 extends once, it stops. During the contraction process of the electric telescopic rod 54, since the support rod 58 supports and positions the already attached first magnet, and the baffle 37 blocks the second magnet, when the first magnet moves vertically downward with the motor rotor, the second magnet is blocked by the baffle 37 and remains in the placement frame 36. That is, an intersecting section is formed between the attached first magnet and the second magnet. When the electric telescopic rod 54 completes one extension, at this time, under the reset of the connecting spring 39, the second magnet is pushed towards the fitting frame on the outer ring surface of the motor rotor and contacts the outer ring surface of the support rod 58. Subsequently, the worker uses the controller to contract the telescopic end of the electric telescopic rod 56, driving the support rod 58 to move vertically upward, and the moving distance is the height of one magnet. When the electric telescopic rod 56 contracts once and stops, under the reset of the connecting spring 39, the second magnet contacts the glue in the inner cavity wall of the fitting frame on the outer ring surface of the motor rotor and is fixed in the fitting frame by the glue. At this time, the second magnet is directly below the first magnet. Repeating the above steps can complete the attachment of multiple magnets;

[0061] When the magnet attachment is completed, the worker uses the controller to vertically move the telescopic end of the electric telescopic rod 54 downward. At this time, the magnet closest to the motor rotor in the placement frame 36 is blocked and positioned by the support rod 58, and the support rod 58 contacts the center position of the magnet. Subsequently, the worker uses the controller to move the upper robotic arm 2 vertically upward. During the vertical upward movement of the upper robotic arm 2, the pressing rod 55 gradually contacts the inclined surface of the trapezoidal block 312 from the vertical surface contacting the trapezoidal block 312. As the pressing rod 55 continues to move vertically upward, under the reset of the return spring 314, the slider 35 and the placement frame 36 move along the chute 34 towards the side close to the fixed seat 313, that is, the placement frame 36 moves away from the motor rotor. During the process of the placement frame 36 moving away from the motor rotor, under the reset of the first spring 44, the rack 43 moves along the slide rail 41 towards the side away from the fixed block 42. During the movement of the rack 43 towards the side away from the fixed block 42, the driving gear 46 and the nut 45 rotate counterclockwise, and the lead screw 47 is inserted back into the interior of the placement frame 36. That is, when the magnet closest to the motor rotor in the placement frame 36 contacts the outer ring surface of the support rod 58, the lead screw 47 is inserted back into the interior of the placement frame 36, thereby limiting the un-attached magnet in the placement frame 36;

[0062] When the upper robotic arm 2 returns to the initial position, the staff operates the controller to cause the telescopic end of the second electric telescopic rod 56 to contract, driving the support rod 58 to return to the initial position. After both the upper robotic arm 2 and the second electric telescopic rod 56 return to the initial position, the staff can remove the motor rotor that has completed the magnet fitting. This motor rotor has completed the magnet fitting work. Repeating the above steps can perform magnet fitting on the next motor rotor.

[0063] During the above process, the magnet pasting component and the limiting component in this device cooperate with each other. The hydraulic equipment is used to move the motor rotor upward, thereby meeting the requirement of fitting multiple magnets. This solves the problem that traditional magnet pasting equipment usually has a single magnet pasting row design. When it is necessary to switch the number of rows, the entire set of equipment needs to be replaced, resulting in low fitting efficiency. In this way, the reconfiguration speed of the industrial robot is improved, and it can adapt to the assembly work of different new energy vehicle motors. One set of equipment can cover multiple magnet arrangement schemes, improving the adaptability of the industrial robot.

[0064] This device can meet the magnet fitting requirements of motor rotors with different diameters. The following are the detailed steps:

[0065] When the number of fitting frames on the outer ring surface of the motor rotor is even, the staff can insert or pull out multiple sliders 35 from the sliding grooves 34, insert or pull out multiple fixed seats 313 from the upper surface of the clamping plate 32, and insert or pull out multiple pressing rods 55 from the slots three on the bottom surface of the clamping ring 52. Thus, on the basis of adapting to a motor rotor with an even number of fitting frames, the gap between the placement frames 36 can be adjusted, and the distance between each placement frame 36 can be kept equal.

[0066] When the number of fitting frames on the outer ring surface of the motor rotor is odd, the staff respectively remove the clamping plate 32 on the tray 31 and the clamping ring 52 at the bottom of the connecting plate 51, and remove another set of magnet pasting component, limiting component, and driving component from the placement rack 11. Align the first insertion block 33 at the bottom of the clamping plate 32 in the other set of magnet pasting component with the first slot on the tray 31 for fixation, and align the second slot on the clamping ring 52 in the other set of driving component with the second insertion block 53 at the bottom of the connecting plate 51 for fixation. Then repeat the above steps. Thus, on the basis of adapting to a motor rotor with an odd number of fitting frames, the gap between the placement frames 36 can be adjusted, and the distance between each placement frame 36 can be kept equal.

[0067] In the above process, the magnetic sticker assembly, the limit assembly and the drive assembly in this device are modularly designed and can be replaced, so as to be adapted to motor rotors with different numbers of fitting frames. On the basis of correcting the fitting accuracy of the magnets, the magnetic sticker requirements for the outer ring surface of the motor rotor with an odd or even number of fitting frames can be further realized, solving the problem that in traditional magnetic sticker equipment, a set of fixed production equipment needs to be designed for each size of motor rotor. When the number of fitting frames of the rotor changes, it will lead to equipment replacement or large-scale adjustment, resulting in cumbersome operation steps. In this way, the diverse production requirements are met.

[0068] The above are only embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
