Description

Technical Field

[0001] This utility model relates to the field of magnetic steel insertion technology, specifically a magnetic steel pushing mechanism. Background Technology

[0002] In existing motor rotor manufacturing technology, the insertion of magnets into the rotor has been fully automated. Before a robotic arm inserts magnets one by one into the corresponding magnet slots on the rotor, a pushing mechanism is typically used to directly push a certain number of magnets into the robotic arm. Existing magnet pushing mechanisms generally use cylinders for linear reciprocating motion. Before pushing, a row of magnets is placed in a corresponding guide slot, and the reciprocating movement of the cylinder pushes the magnets directly into the corresponding robotic arm. Because the cylinder requires a large lateral space for reciprocating linear motion, the entire automated magnet insertion equipment cannot be installed in a small space. Furthermore, when the cylinder pushes the magnets into the guide slots, there is sliding friction between the magnets and the bottom surface of the guide slots. After prolonged operation, severe wear occurs on the bottom surface of the guide slots. When severe wear occurs, the guide slots must be replaced, thus reducing their service life. Utility Model Content

[0003] The purpose of this invention is to provide a magnet pushing mechanism that occupies little lateral space, making it easy to install and use in a small installation space. During the magnet pushing and moving process, the bottom surface of the magnet pushing guide groove moves synchronously with the bottom surface of the magnet, eliminating the problem of relative sliding friction, thereby improving the service life of this invention.

The conveyor belt is disposed on the supporting base plate, and two guide limiting plates are fixedly disposed parallel to each other on the supporting base plate and distributed along the length direction of the conveyor belt. The bottom plane of the guide limiting plate is in contact with the upper plane of the conveyor belt. The sides of the two guide limiting plates and the upper plane of the conveyor belt form a magnetic steel pushing guide groove. The pushing component includes a push plate, which is located in the magnetic steel pushing guide groove. The driving mechanism can drive the conveyor belt and the push plate to reciprocate synchronously, and the controller can control the operation of the driving mechanism.

[0005] Preferably, the pushing assembly further includes an I-shaped connecting rod and a support rod.

Detailed Implementation

[0020] The following will describe specific embodiments and appendices. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described using a push guide groove. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] This utility model provides a magnetic steel pushing mechanism (such as...) Figure 1 As shown, the device includes a support base plate 1, a conveyor belt 2, a drive mechanism, a pushing assembly, guide limit plates 5, and a controller. The support base plate 1 provides overall support for the entire device and can be part of the workbench of the automatic steel insertion equipment. In this technical solution, the conveyor belt 2 is mainly used to support and push the moving magnets. The conveyor belt 2 is mounted on the support base plate 1 and can rotate freely. Two guide limit plates 5 are fixedly mounted parallel to each other on the support base plate 1 and distributed along the length of the conveyor belt 2. The bottom plane of the guide limit plate 5 is in contact with the upper plane of the conveyor belt 2. The sides of the two guide limit plates 5 and the upper plane of the conveyor belt 2 form a magnet pushing guide groove 101. In actual application, a row of magnets is directly placed into the magnet pushing guide groove 101 by a robotic arm. The specific dimensions of the magnet pushing guide groove 101 are as follows. The dimensions can be set according to the size of the magnet so that the magnet push guide groove 101 can prevent the magnet from tilting in the front-to-back direction and effectively ensure the smooth left-to-right movement of the magnet. The push component includes a push plate 41, which is located in the magnet push guide groove 101. The drive mechanism can drive the conveyor belt 2 and the push plate 41 to move back and forth synchronously. In actual application, the conveyor belt 2 drives the push plate 41 to move in the magnet push guide groove 101 during rotation. The movement of the push plate 41 can continue to push the magnet that has detached from the magnet push guide groove 101, so that the magnet can completely detach from the magnet push guide groove 101 and smoothly enter the magnet slot in the robotic arm. The controller can control the operation of the drive mechanism. In this specific embodiment, the controller can be a PLC controller, which is known and commonly used in the field of industrial automation technology.

[0022] Based on the above embodiments, the specific implementation of the conveyor belt 2 on the support base plate 1 is as follows: a driven support roller 22 and a driven support roller 21 are arranged on the support base plate 1, which are arranged in opposite directions. Both ends of the driven support roller 22 and the driven support roller 21 are connected to the support base plate 1 through a support seat 11. The driven support roller 22 and the driven support roller 21 can rotate freely relative to the support seat 11. The conveyor belt 2 is sleeved on the driven support roller 22 and the driven support roller 21. Furthermore, in order to facilitate the fixed setting of the two guide limiting plates 5, two first support columns 12 are fixedly set on the outside of each guide limiting plate 5. The bottom of the first support column 12 is fixedly connected to the support base plate 1.

[0023] Based on the above embodiments, the specific implementation of the pushing component is as follows: the pushing component further includes an 1 / 2-shaped connecting rod 42 and a support rod 43. The lower part of the 1 / 2-shaped connecting rod 42 is connected to the front and rear sides of the conveyor belt 2. The bottom sides of the 1 / 2-shaped connecting rod 42 can be fixedly connected to the conveyor belt 2 by clamping or riveting. After the above fixed connection, the 1 / 2-shaped connecting rod 42 can be synchronously driven to move synchronously during the movement of the conveyor belt 2. A first guide groove 51 is provided on the guide limiting plate 5 along its length direction. The upper crossbar 42 of the 1 / 2-shaped connecting rod 42 is sleeved in the two first guide grooves 51. The two support rods 43 are fixedly set on the left side wall of the crossbar 42. The push plate 41 is set on the left side of the two support rods 43. In practical applications, the length of the support rod 43 is used to achieve relative isolation between the push plate 41 and the 1 / 2-shaped connecting rod 42. Then, after the 1 / 2-shaped connecting rod 42 moves to the end, the push plate 41 can be completely separated from the magnet push guide groove 101. Then, the push plate 41 is used to completely push the magnet into the corresponding magnet groove of the robotic arm. To facilitate the adjustment of the distance between the push plate 41 and the crossbar 421, the support rod 43 is made into a telescopic rod. Specifically, the support rod 43 includes a fixed rod 431 and a telescopic rod 432. The fixed rod 431 is fixedly connected to the crossbar 421, and the telescopic rod 432 is sleeved on the fixed rod 431 and can slide left and right relative to the fixed rod 431. A set screw for pressing and fixing the telescopic rod 432 is provided on the fixed rod 431. Furthermore, to improve the movement stability of the crossbar 421 in the first guide groove 51, the first guide groove 51 is made into a square groove, and the crossbar 421 is made into a square rod. The upper and lower side walls of the crossbar 421 are respectively fitted to the upper and lower side walls of the first guide groove 51. The first guide groove 51 limits the movement of the crossbar 421, thereby improving the movement stability of the crossbar 421.

[0024] Based on the above embodiments, in order to improve the levelness of the running section of the conveyor belt 2 and thus improve the movement stability of the magnets thereon, a support plate 23 is provided at the bottom of the running section of the conveyor belt 2, and the upper surface of the support plate 23 is in contact with the bottom surface of the running section of the conveyor belt 2.

[0025] In actual operation, to facilitate the smooth forward sliding of the magnets detached from the conveyor belt 2, a transition plate 6 is provided on the left side of the conveyor belt 2. The two ends of the transition plate 6 are fixedly connected to the bottom of the guide limiting plate 5. The upper surface of the transition plate 6 is flush with the upper surface of the conveyor belt 2, and it is adjacent to the left end of the conveyor belt 2. When the conveyor belt 2 moves the magnets, after the leftmost magnet detaches from the conveyor belt 2, it moves directly onto the transition plate 6. As the conveyor belt 2 continues to move, subsequent moving magnets propel the magnets on the transition plate 6. Once all magnets have detached from the conveyor belt 2, the pusher plate 41 continues to push the magnets, thus pushing them into the corresponding magnetic slots of the robotic arm. After the magnets are pushed, the conveyor belt 2 rotates in the opposite direction, allowing the pusher plate 41 to return to its initial position.

[0026] Based on the above embodiments, the specific implementation of the driving mechanism is as follows: The driving mechanism includes a drive motor 31, a synchronous belt 32, a driving synchronous pulley 33, and a driven synchronous pulley 34. The driving synchronous pulley 33 is fixedly disposed at one end of the driving support roller 21 of the conveyor belt 2, and the driven synchronous pulley 34 is fixedly disposed at one end of the driven support roller 22 of the conveyor belt 2. The synchronous belt 32 is sleeved on the driving synchronous pulley 33 and the driven synchronous pulley 34. The drive motor 31 is used to drive the driving synchronous pulley 33 to rotate. Specifically, the drive motor 31 is connected to the end of the driving support roller 21. The drive motor 31 can rotate in both directions. By utilizing the connecting effect of the synchronous belt 32, the drive motor 32 can drive the conveyor belt 2 to perform stable forward and reverse rotation, thereby ensuring that the push plate 41 can move stably left and right.

[0027] Based on the above embodiments, in order to further improve the moving accuracy of the push plate 41, the pushing mechanism is preferably made to include a first photoelectric detection switch 71 and a second photoelectric detection switch 72. Specifically, both the first photoelectric detection switch 71 and the second photoelectric detection switch 72 are fixedly installed on the support base plate 1 using a second support column 13. Both the first photoelectric detection switch 71 and the second photoelectric detection switch 72 are electrically connected to the controller. The first photoelectric detection switch 71 is used to detect the I-shaped connecting rod 42 at the initial position, and the second photoelectric detection switch 72 is used to detect the I-shaped connecting rod 42 at the termination position.

[0028] When a row of magnets is placed in the magnet pushing guide groove 101, the controller starts the drive motor 31. Driven by the drive motor 31, the conveyor belt 2 begins to slowly move the magnets and push plate 41 to the left. During the continuous leftward movement of the conveyor belt 2, when the second photoelectric detection switch 72 detects the 1 / 2-shaped connecting rod 42, the controller stops the drive motor 31 based on the detection signal issued by the second photoelectric detection switch 72. After the drive motor 31 stops, the push plate 41 synchronously pushes the magnets. After the drive motor 31 stops for a certain period of time, the controller starts the drive motor 31 again to reverse it, thereby realizing the reset movement of the conveyor belt 2 and the push plate 41. When the first photoelectric detection switch 71 detects the 1 / 2-shaped connecting rod 42, the controller stops the drive motor 31 based on the detection signal issued by the first photoelectric detection switch 71. After the drive motor 31 stops, the conveyor belt 2 and the push plate 41 return to their initial working positions, thus facilitating the next magnet pushing operation.

[0029] In this utility model, "front", "rear", "up", "down", "left", and "right" are all relative positions used to facilitate the description of positional relationships, and therefore cannot be understood as absolute positions as a limitation on the scope of protection.

[0030] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

However, the present invention is not limited to the above embodiments and examples. For those skilled in the art, several improvements and modifications can be made without departing from the concept of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
