In recent years, with the rapid development of new energy vehicles, charging piles and energy storage industries, the application of relays has become more and more extensive. Among them, magnetic steel is one of the important parts required for relays. Due to the particularity of magnetic steel materials, the magnetic steel needs to be weakly magnetized first when used, and then the magnetic steel is strongly magnetized after the weak magnetization is completed. Therefore, the magnetic steel used in general relays has a certain magnetism after preliminary magnetization, but it has not reached the required magnetism for use, and it needs to be magnetized again. However, most of the existing magnetization technologies still rely heavily on manual operation, with high labor intensity and low efficiency, which directly slows down the production efficiency of the entire magnetization process, especially when putting the magnetic steel into the magnetization device and taking the magnetic steel out of the magnetization device, it also has certain damage to the human body; and when the existing magnetic steel is loaded after magnetization to be assembled with other parts of the relay, it is still manually transported to the assembly machine for loading, so there is also a problem of low loading efficiency, which cannot effectively meet the production requirements of the automated production line.

[0024] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0025] See also Figures 1 to 8 The utility model provides a magnetic steel magnetizing and feeding device 100, which is used for automatically magnetizing a magnetic steel 200 and transferring and feeding the magnetized magnetic steel 200, wherein the device is not only suitable for magnetizing and feeding magnetic steel for relays, but also can be used for magnetizing and feeding magnetic steel for other electronic products, and is not limited thereto, and the cross-section of the magnetic steel 200 can be square, circular, U-shaped or other irregular shapes. In general, the magnetic steel magnetizing and feeding device 100 provided in the preferred embodiment of the utility model includes a magnetizing box 10, a quick-change mechanism 20 and a receiving mechanism 30 arranged on the upper and lower opposite sides of the magnetizing box 10, a separation mechanism 40 and a pick-up and delivery mechanism 50 arranged on the front and rear opposite sides of the magnetizing box 10, and a reversing mechanism 60 arranged between the separation mechanism 40 and the pick-up and delivery mechanism 50. The quick-change mechanism 20 has a plurality of bins 21, which are used for accommodating and stacking the magnetic steel 200. The quick-change mechanism 20 is mainly used to push the plurality of bins 21, each stacked with a plurality of magnetic steels 200, to the feed port 10a of the magnetizing box 10 in sequence for feeding. The separation mechanism 40 has a support member 41 arranged between the discharge port 10b of the magnetizing box 10 and the receiving mechanism 30, and the support member 41 is used to receive the magnetized magnetic steel 200. The receiving mechanism 30 has a receiving member 31 that moves up and down. The receiving member 31 moves upward to pass through the through hole 41a of the support member 41 and the discharge port 10b of the magnetizing box 10, and then receives the magnetic steel 200 in the bin 21 at the feed port 10a of the magnetizing box 10, and supports the magnetic steel 200 downward to the magnetizing box 10 for magnetization, and also continues to support the magnetized magnetic steel 200 downward to be placed on the support member 41. The separation mechanism 40 also pushes the magnets 200 on the supporting member 41 onto the reversing mechanism 60 one by one through the pushing member 42 that moves left and right. The reversing mechanism 60 is used to rotate the magnets 200 to a certain angle so that the picking and delivering mechanism 50 can pick up and deliver the magnets 200.

[0026] Specifically, the feed port 10a and the discharge port 10b of the magnetizing box 10, the through hole 41a of the support 41 and the receiving member 31 are coaxially arranged, thereby optimizing the structure, facilitating alignment and effectively shortening the moving stroke of each device. Among them, the receiving member 31 is rod-shaped, and the shape of its supporting surface corresponds to the shape of the magnetic steel 200. The support 41 is plate-shaped, and the push member 42 is rod-shaped, plate-shaped or block-shaped. In addition, the size of the cross section of the through hole 41a on the support 41 is larger than the size of the cross section of the receiving member 31 and smaller than the size of the cross section of the magnetic steel 200, so that the receiving member 31 can smoothly pass through the support 41 to enter the magnetizing box 10 to receive materials, and when the magnetizing box 10 and the support 41 are withdrawn downward, a stack of magnetic steels 200 after magnetization is placed on the support 41, wherein only the bottom layer of magnetic steels 200 stays on the support 41, and the rest of the magnetic steels 200 are still retained in the magnetizing box 10. Specifically, in some embodiments, the support member 41 is a U-shaped plate, the open end of which is opposite to the push member 42, the sealed end is opposite to the reversing mechanism 60, the through hole 41a corresponds to a U-shaped hole, the receiving member 31 enters and exits the through hole 41a vertically from the bottom of the open end of the support member 41, and the push member 42 enters and exits the through hole 41a horizontally from the left side of the open end of the support member 41. Of course, in other embodiments, the support member 41 can also be a rectangular plate, the through hole 41a is a strip hole arranged along the left and right directions, the receiving member 31 still enters and exits the through hole 41a vertically from the bottom, and the push member 42 can enter the through hole 41a from the edge of the bottom side of the support member 41 and move horizontally in the through hole 41a to push the material; the through hole 41a can also be a circular hole or a square hole, which is only for the receiving member 31 to enter and exit, and the push member 42 can directly push the magnetic steel 200 to the right from the left side or the front and rear sides of the support member 41.

[0027] See also Figures 1 to 4Specifically, the magnetizing box 10 is provided with coils and circuits and other components for magnetizing, and the box is also provided with power connection ports and magnetic field adjustment components. The magnetizing principle is well known in the art and will not be described here. Among them, a magnetizing channel is formed in the box body of the magnetizing box 10, which runs through the box body from top to bottom, and a feed port 10a and a discharge port 10b are formed at the upper and lower ends of the box body respectively. The magnetic steel 200 to be magnetized enters the magnetizing box 10 from the feed port 10a for magnetization, and leaves the magnetizing box from the discharge port 10b after magnetization. Among them, the magnetizing channel also has a guide part formed by the cavity structure of the box body itself, which is used to guide each magnetic steel 200 to prevent the stacked magnetic steels 200 from shifting during the downward movement, so as to ensure that each magnetic steel 200 can fall vertically onto the supporting member 41. Moreover, only the bottom layer of magnetic steel 200 falls on the supporting member 41 each time, and the rest of the upper layer of magnetic steel 200 is still in the magnetization channel. After the push member 42 pushes away the bottom layer of magnetic steel 200 each time, another piece of magnetic steel 200 falls in the magnetization channel. Of course, a guide member 11 can also be added to the magnetization channel, and the upper and lower ports of the guide member 11 are flush with the feed port 10a and the discharge port 10b of the box body, and are slightly smaller than the feed port 10a and the discharge port 10b. The magnetic steel 200 directly enters the guide member 11 at the feed port 10a for magnetization, and is guided and limited by its inner wall. Alternatively, the upper port of the guide member 11 can also extend from the feed port 10a of the box body and protrude from the outside of the box body to facilitate the alignment and discharge of the silo 21.

[0028] See also Figures 1 to 4 Specifically, the quick-change mechanism 20 also includes a positioning platform 22 and a driving member 23. The positioning platform 22 is mounted on the magnetizing box 10 and has a discharge port 22a aligned with the feed port 10a. The driving member 23 is used to drive the various bins 21 arranged on the positioning platform 22 to move or rotate, so that the lower ports of the various bins 21 are aligned with the discharge port 22a in turn, and the magnetic steel 200 stacked therein can enter the magnetizing channel. Among them, the upper port of the bin 21 is used to put the magnetic steel 200, and its lower port is in contact with the table surface of the positioning platform 22, so that the magnetic steel 200 stacked therein can be driven to move and rotate relative to the positioning platform 22 until it moves to the discharge port 22a, and the discharge operation can be realized. Among them, multiple bins 21 can be arranged linearly on the positioning platform 22 along the left-right direction, such as 9 bins 21 are arranged in a row, and 40 magnetic steels 200 are stacked in each bin from top to bottom. More bins 21 can be arranged in a matrix. Of course, the bins 21 can also be arranged along the circumference of the positioning platform 22. The driving member 23 can be adjusted by a manual knob. Preferably, the driving member 23 uses a driving motor to automatically drive each bin 21 to move linearly or rotate.

[0029] See also Figures 1 to 4Specifically, the receiving mechanism 30 further includes a lifting motor 32, which is connected to the receiving member 31 and used to drive the receiving member 31 to move up and down. Specifically, the separation mechanism 40 further includes a pushing cylinder 43, which is connected to the pushing member 42 and used to drive the pushing member 42 to move left and right. In order to effectively ensure that each magnetic steel 200 is accurately positioned and pushed onto the reversing mechanism 60, a limiting member 44 is further provided on the supporting member 41. The limiting member 44 is detachably mounted on the supporting member 41 and is used to guide and limit the movement of each magnetic steel 200 on the supporting member 41 from the top and the front and rear sides, thereby preventing the magnetic steel 200 from shifting and preventing the abutting magnetic steels 200 from turning over during the abutting and pushing process. In addition, when the magnets 200 provided by a silo 21 are supplied to the tailings, the last few pieces of magnets 200 are easily driven to flip over when the pushing member 42 pushes the magnets 200 on the bottom layer. For this reason, a blocking member 45 is also provided at the left end of the supporting member 41. The blocking member 45 moves linearly in the left and right directions under the drive of the blocking cylinder 46 connected thereto, so as to enter the magnetization channel from the side opening at the lower end of the guide member 11 or the side opening at the lower end of the magnetization box 10, so as to prevent the tailings from flipping over from above.

[0030] See also Figure 5 and Figure 6 Specifically, the reversing mechanism 60 includes a support seat 61, a rotating motor 62 mounted on the support seat 61, and a turntable 63 rotatably arranged on the support seat 61. The circumference of the turntable 63 is evenly distributed with at least two placement grooves 63a. The turntable 63 rotates under the drive of the rotating motor 62 connected thereto, so that the at least two placement grooves 63a respectively have a receiving position flush with the support member 41 and a feeding position perpendicular to the support member 41. Specifically, there are 4 placement grooves 63a evenly distributed on the turntable 63, which drive the magnetic steel 200 to rotate 90° each time, effectively improving the reversing and feeding efficiency. Among them, the turntable 63 is rotatably arranged on the support seat 61 through a rotating shaft 64, and the rotating shaft 64 is connected to the output shaft of the rotating motor 62 through a synchronous belt 65, so that the turntable 63 rotates under the drive of the rotating motor 62. Of course, the outer side of the synchronous belt 64 is also covered with a protective cover 66. In addition, the turntable 63 includes two circular rotating parts 631 arranged in parallel and at intervals at the output end of the rotating motor 62, and the two rotating parts 631 are correspondingly arranged with a clamping groove 631a, and the correspondingly arranged clamping grooves 631a cooperate to form a placement groove 63a for the magnet 200 to be placed. The magnet 200 is carried between the two rotating parts 631 with a certain distance, which not only effectively improves the stability during the rotation process, but also facilitates the pick-up and delivery mechanism 50 to clamp the magnet 200 in the gap. Further, the spacing between the two rotating parts 631 on the rotating shaft 64 is adjustable, so as to adapt to the acceptance of magnets 200 of different sizes.

[0031] See also Figure 7 and Figure 8Specifically, the pick-up and delivery mechanism 50 includes a three-axis linear module 51, two clamping cylinders 52 connected to the output end of the three-axis linear module 51, and two clamping claws 53 connected to the output ends of the two clamping cylinders 52 in a one-to-one correspondence. The two clamping claws 53 are driven by the corresponding clamping cylinders 52 to open and close to clamp the magnetic steel 200, and are driven by the three-axis linear module 51 to move linearly in the up-down, left-right and front-back directions. Further, the pick-up and delivery mechanism 50 also includes an adjusting cylinder 54 arranged between the three-axis linear module 51 and the two clamping cylinders 52. The adjusting cylinder 54 is used to drive the two clamping cylinders 52 connected thereto to move toward or away from each other, so as to drive the two clamping claws 53 to move so as to change the distance between the two, and further adapt to the clamping operation of magnetic steel 200 of different sizes, and adapt to the pick-up and delivery of the magnetic steel 200 between the clamping position and the loading position with different distances.

[0032] See also Figures 1 to 4 The magnetic steel magnetizing and feeding device 100 of the utility model also includes a pressing mechanism 70 disposed above the quick-change mechanism 20. The pressing mechanism 70 has a pressing member 71 that moves up and down. The pressing member 71 passes downward through the silo 21 and enters the magnetizing box 10 through the feed port 10a to abut against the magnetic steel 200 on the top layer, thereby preventing the magnetic steel 200 from shaking during the magnetizing process and effectively improving the magnetizing effect. Specifically, the pressing mechanism 70 also includes a mounting frame 72 mounted on the top side end of the magnetizing box 10 and a pressing cylinder 73 mounted on the mounting frame 72. The pressing member 71 is connected to the output end of the pressing cylinder 73, so that it moves up and down under the drive of the pressing cylinder 73. Among them, the pressing member 71 is also rod-shaped and is coaxially arranged with the feed port 10a of the magnetizing box 10.

[0033] See also Figure 1 , Figure 5 and Figure 6 The magnetic steel magnetizing and feeding device 100 of the utility model further includes a detector 80, which is arranged at the output end of the separation mechanism 40 or the input end of the reversing mechanism 60, and is used to detect the magnetic pole and magnetic flux of the magnetic steel 200. The detector 80 specifically uses a Gauss meter to detect the polarity and magnetic flux, so that the pick-up and delivery mechanism 50 can perform shunt feeding of the magnetic steel 200 according to the detection results.

[0034] See below Figures 1 to 8 , the working principle of the magnetic steel magnetizing and feeding device 100 of the utility model is described:

[0035] First, after each bin 21 is filled with the magnets 200 to be magnetized manually, the device is started and enters the automatic operation mode. The quick-change mechanism 20 pushes one of the bins 21 to the discharge port 22a. At the same time, the receiving member 31 rises to the feed port 10a to receive the magnets 200. Then, the receiving member 31 moves downward to the magnetization position together with the magnets 200 in the bin 21. The downward pressure cylinder 73 then drives the downward pressure member 71 downward through the bin 21 to abut against the magnets 200 on the top layer in the magnetization box 10. Then, the magnetization box 10 is activated to magnetize each magnetic sheet 200 in its magnetization channel. After that, the receiving member 31 continues to move downward to place the magnetized stack of magnets 200 on the supporting member 41. The pushing member 42 then moves in the left and right direction to push the bottom magnet 200 onto the reversing mechanism 60, where the detector 80 first detects the magnet polarity and magnetic flux, and the reversing mechanism 60 then rotates the magnet 200 90°, and the pick-and-place mechanism 50 diverts and transfers the magnet 200 according to the detection result, and the qualified products are transferred to the assembly station, and the unqualified products are transferred to the unqualified product collection box; after all the magnets 200 in the bin 21 are taken out, the quick-change mechanism 20 pushes another bin 21 to the discharge port 22a for feeding, and continues to magnetize and transfer the magnets 200 provided by the bin 21 until all the bins 21 are fed, refill the magnets 200, and repeat the above operation.

[0036] Compared with the prior art, in the magnet magnetizing feeding device 100 disclosed in the utility model, the receiving member 31 of the receiving mechanism 30 moves up and down, and sequentially passes through the through hole 41a of the supporting member 41 and the material outlet 10b of the magnetizing box 10 from the bottom to the top, and then receives the magnet 200 supplied by the silo 21 above the magnetizing box 10 at the material inlet 10a of the magnetizing box 10, and the receiving member 31 also supports the received magnet 200 downward into the magnetizing box 10, and after magnetization is completed in the magnetizing box 10, the magnetized magnet 200 is further supported downward to be placed on the supporting member 41, and then the receiving member 31 moves up and down. The magnetizing operation of multiple magnets 200 stacked in the silo 21 can be realized each time, and the magnetizing and transferring efficiency is high. Combined with the left and right movement of the pushing member 42 of the separation mechanism 40, the magnets 200 on the supporting member 41 are pushed onto the reversing mechanism 60 one by one in turn, and the reversing mechanism 60 rotates the magnets 200 by a certain angle to make them in a position convenient for the picking and delivering mechanism 50 to pick up and deliver, thereby effectively improving the transfer and feeding efficiency. The entire magnet magnetizing and feeding device 100 has a simple structure, a reasonable layout, high magnetizing and feeding efficiency, and the design of multiple silos 21 effectively improves production capacity and reduces feeding time, thereby improving production efficiency.

[0037] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
