[0034] The present utility model will be further described in conjunction with the accompanying drawings and specific embodiments.

[0035] This embodiment provides an automatic magnet feeding device, as Figures 1 to 16 shown, which includes a workbench 1, a magnetic material clamp 2, a limit plate 3, a pushing device 4, and a material transferring device 5; a limit plate 3 is provided on the workbench 1, the magnetic material clamp 2 is vertically arranged on the limit plate 3 in the longitudinal direction, the pushing device 4 is arranged on the workbench 1, and the moving direction of the pushing device 4 is perpendicular to the magnetic material clamp 2; a plurality of feeding channels 10 are provided on the workbench 1, a plurality of pushing channels 30 are provided on the limit plate 3, one end of the feeding channel 10 is communicated with the pushing channel 30, and the discharge port of the magnetic material clamp 2 corresponds to the pushing channel 30; a limit groove 34 is provided on the limit plate 3, and the limit groove 34 is communicated with the other end of the pushing channel 30. The pushing device 4 is used to push the magnets 7 in the feeding channel 10 and the magnetic material clamp 2 into the limit groove 34 through the pushing channel 30 to realize the positioning and arrangement of the magnets 7; the material transferring device 5 is arranged on the workbench 1 and is used to transport the arranged magnets 7 in the limit groove 34 to the jig 60.

[0036] The workbench 1 of this embodiment includes a bottom plate 11, a top plate 12, and support columns 13 arranged between the bottom plate 11 and the top plate 12. The area of the top plate 12 is smaller than that of the bottom plate 11. The magnetic material clamp 2, the pushing device 4, and the limit plate 3 are all arranged on the top plate 12. One end of the feeding channel 10 is communicated with the pushing channel 30, and the limit groove 34 is communicated with the other end of the pushing channel 30. By adjusting the dimensions and layouts of the feeding channel 10, the pushing channel 30, and the limit groove 34, the feeding requirements of magnets 7 with different specifications and shapes can be flexibly adapted, enhancing the versatility of the equipment. The pushing device 4 pushes the magnets 7 in the feeding channel 10 and the magnetic material clamp 2 into the limit groove 34 through the pushing channel 30 to realize the positioning and arrangement of the magnets 7, and the material transferring device 5 transports the arranged magnets 7 in the limit groove 34 to the jig 60, realizing the automatic processing of the magnets 7 from the feeding channel 10 and the magnetic material clamp 2 to the jig 60, significantly improving the production efficiency and production speed, and at the same time avoiding errors and losses caused by human factors.

[0037] As Figures 1 to 4As shown, it further includes a first cover plate 49. The pushing device 4 includes a pushing cylinder 41 and a push rod 42. The first cover plate 49 is covered on the workbench 1 and is located above the limiting plate 3. The pushing cylinder 41 is fixedly arranged on the first cover plate 49. One end of the push rod 42 is fixedly arranged at the output end of the pushing cylinder 41, and the other end of the push rod 42 extends into the pushing channel 30. The setting of the first cover plate 49 in this embodiment enables the pushing cylinder 41 to be stably fixed on the workbench 1, and the first cover plate 49 is covered at the connection of the feeding channel 10 and the pushing channel 30, which can play a role in limiting the magnet 7. The pushing cylinder 41 serves as a power source. By precisely controlling the expansion and contraction of the cylinder, the precise pushing of the push rod 42 can be realized, thereby ensuring that the magnet 7 is stably and accurately pushed in the pushing channel 30.

[0038] As Figures 1 to 7 shown, it further includes a first connecting block 43 and a second connecting block 44. The number of the feeding channels 10 is two, and the number of the pushing channels 30 is four. The pushing cylinder 41 includes a first pushing cylinder 411 and a second pushing cylinder 412. The push rod 42 includes a first push rod 421 and a second push rod 422. Two first pushing cylinders 411 are respectively arranged on the first cover plate 49. One ends of the two first push rods 421 are respectively fixed at the output ends of the first pushing cylinders 411 through the first connecting block 43, and the other ends of the two first push rods 421 respectively extend into the pushing channel 30. The second pushing cylinder 412 is arranged on the first cover plate 49. One ends of the two second push rods 422 are fixed at the output ends of the second pushing cylinders 412 through the second connecting block 44, and the other ends of the two second push rods 422 respectively extend into the pushing channel 30. The first push rod 421 and the second push rod 422 are arranged at intervals.

[0039] In this embodiment, by increasing the number of the pushing cylinders 41 and the push rods 42, the magnets 7 in multiple feeding channels 10 can be pushed simultaneously, significantly improving the pushing speed and production efficiency of the magnets 7. The reasonable configuration of the numbers of the feeding channels 10 and the pushing channels 30 enables the device to flexibly adapt to the requirements of different production scenarios. The first connecting block 43 and the second connecting block 44 respectively fix the first push rod 421 and the second push rod 422 at the output ends of the pushing cylinders 41, enhancing the connection stability between the push rod 42 and the cylinder. In this embodiment, the number of the feeding channels 10 is set to two, and the number of the pushing channels 30 is set to four. Correspondingly, the number of the first pushing cylinders 411 is two, and the number of the first push rods 421 is two. The magnetic material clamp 2 can accommodate two groups of magnets 7, so that the number of magnets 7 in each magnetic component is four. In other embodiments, the accommodation numbers of the feeding channels 10, the pushing channels 30, and the magnetic material clamp 2 can be set accordingly according to actual requirements.

[0040] As Figure 12 and Figure 13As shown, at the other ends of the first ejector rod 421 and the second ejector rod 422 in this embodiment, suction blocks 45 are provided. The suction blocks 45 are used to adsorb the magnets 7 in the material pushing channel 30. With the assistance of the suction blocks 45, the ejector rods 42 can be more stable when pushing the magnets 7. The tight adsorption between the suction blocks 45 and the magnets 7 reduces the shaking or bouncing of the magnets 7 caused by the impact force during the pushing process, thereby improving the stability and accuracy of the pushing.

[0041] As Figures 1 to 4 and Figure 14 shown, it further includes a material pressing cylinder 46, a first bracket 461, a pressing block 462, a first detection optical fiber 47 and a second detection optical fiber 48. The first bracket 461 is arranged on the workbench 1, the material pressing cylinder 46 is arranged on the first bracket 461, the output end of the material pressing cylinder 46 is provided with the pressing block 462, and the material pressing cylinder 46 drives the pressing block 462 to abut against the magnet 7 in the feeding channel 10. The first detection optical fiber 47 is arranged on the workbench 1 below the magnet 7 in the feeding channel 10, and the second detection optical fiber 48 is arranged on the magnetic material clamp 2.

[0042] The material pressing cylinder 46 in this embodiment drives the pressing block 462 to press down and abut against the magnet 7 in the feeding channel 10. Since multiple magnets 7 in the feeding channel 10 attract each other and are arranged in a long strip, when the pressing block 462 abuts against several magnets 7, except for the magnet 7 at the connection of the feeding channel 10 and the material pushing channel 30 that can be pushed by the pushing device 4, the other magnets 7 in the feeding channel 10 can stay stably in the feeding channel 10, and the magnet 7 in the magnetic material clamp 2 will automatically drop into the material pushing channel 30 due to gravity. Through the first detection optical fiber 47 and the second detection optical fiber 48, the operator can detect the remaining number of magnets 7 in the feeding channel 10 and the magnetic material clamp 2. When the first detection optical fiber 47 and the second detection optical fiber 48 are triggered, the entire device stops and alarms, which is convenient for the operator to replenish materials and ensures the smooth progress of the feeding process.

[0043] As Figure 4 and Figure 5 、 Figure 7 and Figure 8 shown, at the position corresponding to the connection of the limiting plate 3 with the feeding channel 10 and the material pushing channel 30, a first anti-fooling magnet 31 is provided. The first anti-fooling magnet 31 is used to adsorb the magnet 7 in the feeding channel 10 into the material pushing channel 30; at the position corresponding to the discharge port of the magnetic material clamp 2 on the limiting plate 3, a second anti-fooling magnet 32 is provided. The second anti-fooling magnet 32 is used to adsorb the magnet 7 at the discharge port of the magnetic material clamp 2 in the material pushing channel 30; on the side of the limiting groove 34 facing away from the material pushing channel 30, a third anti-fooling magnet 33 is provided. The third anti-fooling magnet 33 is used to adsorb the magnets 7 arranged in the positioning groove.

[0044] In this embodiment, the first anti-fool magnet 31 is arranged at the connection between the feeding channel 10 and the pushing channel 30 to ensure that the magnet 7 smoothly and accurately enters the pushing channel 30 from the feeding channel 10. Through the adsorption effect, it can also ensure the automatic replenishment of the magnet 7 in the feeding channel 10. The second anti-fool magnet 32 is located at a position corresponding to the discharge port of the magnetic material clamp 2 and the limiting plate 3. Its function is to ensure that the magnet 7 released from the discharge port of the magnetic material clamp 2 can stably stay in the pushing channel 30 and wait for the subsequent pushing operation to ensure the smooth progress of the pushing process. The third anti-fool magnet 33 is arranged on the side of the limiting groove 34 away from the pushing channel 30, mainly used to adsorb and fix the magnets 7 that have been arranged in the positioning groove and wait for the subsequent material transfer operation.

[0045] As Figure 1 and Figure 15 shown, it further includes a first adsorption cylinder 35, a first suction plate 352 and a second bracket 351. The second bracket 351 is fixedly arranged on the workbench 1 and is located below the limiting plate 3. The first adsorption cylinder 35 is arranged on the second bracket 351, and the first suction plate 352 is arranged at the output end of the first adsorption cylinder 35. The first adsorption cylinder 35 drives the first suction plate 352 to abut against the lower part of the limiting groove 34 of the limiting plate 3. In this embodiment, the first suction plate 352 is arranged below the limiting plate 3, and the first adsorption cylinder 35 drives the first suction plate 352 to abut against the lower part of the limiting groove 34 of the limiting plate 3 to ensure that the magnets 7 can be accurately arranged in the limiting groove 34 and also ensure the smooth progress of the subsequent material transfer.

[0046] As Figures 1 to 3 , Figure 9 and Figure 10 shown, the material transfer device 5 includes a handling cylinder 51, a material transfer cylinder 52 and a second adsorption cylinder 53. The handling cylinder 51 is arranged on the workbench 1, the material transfer cylinder 52 is arranged at the output end of the handling cylinder 51, the output end of the material transfer cylinder 52 is arranged vertically downward and is provided with a positioning suction head 521, the second adsorption cylinder 53 is arranged at the output end of the material transfer cylinder 52, the output end of the second adsorption cylinder 53 is arranged vertically downward and is provided with a second suction plate 531. The second suction plate 531 is used to adsorb the magnets 7 arranged in the limiting groove 34 on the positioning suction head 521, and the handling cylinder 51 is used to push the magnets 7 on the positioning suction head 521 away from the limiting groove 34.

[0047] In this embodiment, the positioning suction head 521 of the material transfer cylinder 52 cooperates with the second suction plate 531 of the second adsorption cylinder 53, which can adsorb the magnets 7 arranged in the limiting groove 34 on the positioning suction head 521, ensuring that the magnets 7 will not be displaced due to shaking during the material transfer process, thereby affecting the arrangement position of the magnets 7 on the jig 60. Through the push of the handling cylinder 51 and the lifting of the material transfer cylinder 52, the handling process of the magnets 7 from the limiting groove 34 to the jig 60 can be automatically completed, improving the feeding speed and production efficiency. In this embodiment, the moving direction of the output end of the handling cylinder 51 is perpendicular to the moving direction of the material transfer cylinder 52. By the handling cylinder 51, the magnet 7 on the positioning suction head 521 can be pushed away from the limiting groove 34, and the structure is simple.

[0048] As Figure 9 shown, it further includes a first connecting plate 511, a second connecting plate 522, a third connecting plate 532 and a second cover plate 36. The first connecting plate 511 is fixedly arranged at the output end of the handling cylinder 51, and the material transfer cylinder 52 is arranged on the first connecting plate 511. The second connecting plate 522 is fixedly arranged at the output end of the material transfer cylinder 52, the positioning suction head 521 is arranged at the lower end of the second connecting plate 522, the second adsorption cylinder 53 is arranged on the second connecting plate 522, the third connecting plate 532 is arranged at the output end of the second adsorption cylinder 53, the second suction plate 531 is arranged on the third connecting plate 532. The second cover plate 36 is arranged above the limiting groove 34 of the limiting plate 3, and a through groove 361 matching the positioning suction head 521 is opened on the second cover plate 36.

[0049] The first connecting plate 511 of this embodiment is L-shaped, which is convenient for the horizontal movement of the output end of the handling cylinder 51 to push the magnet 7 on the positioning suction head 521 away from the limiting groove 34. Through the hierarchical connection design of the first connecting plate 511, the second connecting plate 522 and the third connecting plate 532, the loading and unloading processes of the material transfer cylinder 52 and the second adsorption cylinder 53 are more convenient, which is beneficial to maintenance. The second cover plate 36 is arranged above the limiting groove 34 of the limiting plate 3, playing a protective role for the magnets 7 in the limiting groove 34. The second cover plate 36 can prevent external sundries from entering the limiting groove 34 and affecting the arrangement and stability of the magnets 7. At the same time, the through groove 361 opened on the second cover plate 36 and matching the positioning suction head 521 ensures that the positioning suction head 521 can smoothly pass through and adsorb the magnets 7.

[0050] As Figure 1As shown in the figure, it further includes a jig plate 61, a slider 62, a guide rail 63, a lead screw 64 and a servo motor 65. The guide rail 63 and the servo motor 65 are arranged on the workbench 1. The lead screw 64 is arranged in the guide rail 63 and is rotationally connected to the servo motor 65. The slider 62 is screwed onto the lead screw 64. A slide seat is arranged on the slider 62. The jig plate 61 for placing the jig 60 is arranged on the slide seat. The servo motor 65 drives the lead screw 64 to rotate and drives the jig 60 on the jig plate 61 to move along the guide rail 63 to the limit groove 34 of the limit plate 3 through the slider 62. The jig 60 is used to receive the magnet 7 on the positioning suction head 521.

[0051] In this embodiment, the servo motor 65 and the guide rail 63 are arranged on the bottom plate 11 of the workbench 1 with a certain height difference, which is convenient for the handling cylinder 51 to push the magnet 7 on the positioning suction head 521 and place it in the jig 60 on the guide rail 63. As the power source, the servo motor 65 can accurately control the rotation of the lead screw 64, and can accurately control the position of the slider 62, ensuring that the jig 60 on the jig plate 61 can accurately move to the limit groove 34 of the limit plate 3, thus realizing the accurate handling and positioning of the magnet 7.

[0052] Taking the limit plate 3 as the center, two groups of magnetic material clamps 2 are symmetrically arranged on the limit plate 3. Correspondingly, the feeding channels 10 and the pushing devices 4 on the workbench 1 are also symmetrically arranged in two groups on the left and right. The material transfer device 5 is arranged on the workbench 1. Through the material transfer device 5, two groups of arranged magnets 7 in the limit grooves 34 can be transported simultaneously, which can further improve the production efficiency. Of course, in other embodiments, corresponding settings can also be made according to actual needs.

[0053] The using process of the present utility model is as follows:

[0054] Preparation work: Place the magnets 7 in the feeding channel 10 and the magnetic material clamps 2, and place the jig 60 on the jig plate 61 of the material transfer device 5. When the first detection optical fiber 47 of the feeding channel 10 is triggered, the number of magnets 7 in the feeding channel 10 is insufficient, and the device stops and alarms. When the second detection optical fiber 48 of the magnetic material clamp 2 is triggered, the number of magnets 7 in the magnetic material clamp 2 is insufficient, and the device stops and alarms.

[0055] Start the device. The first adsorption cylinder 35 drives the first suction plate 352 to rise and abut against the top plate 12 of the workbench 1 below the limit plate 3. The pressing cylinder 46 drives the pressing block 462 to descend and abut against the magnet 7 in the feeding channel 10. Since the long strip-shaped magnet 7 in the feeding channel 10 is composed of multiple magnets 7 attracting each other in an array, the frictional force at the bottom of the magnet 7 is greater than the suction force of the first anti-fooling magnet 31. Except for the magnet 7 at the connection between the feeding channel 10 and the pushing channel 30 that can be pushed by the pushing device 4, the other magnets 7 in the feeding channel 10 can stay stably in the feeding channel 10.

[0056] The first pusher cylinder 411 drives the first ejector rod 421 to push the magnet 7 at the connection of the feeding channel 10 and the pusher channel 30 to move along the pusher channel 30. At the same time, the second pusher cylinder 412 drives the second ejector rod 422 to push the magnet 7 at the discharge port of the magnetic material clamp 2 to move along the pusher channel 30. The suction blocks 45 of the first ejector rod 421 and the second ejector rod 422 can stably hold the magnet 7 in the pusher channel 30 until the magnet 7 is pushed into the limit groove 34 of the limit plate 3. The magnets 7 arranged in the limit groove 34 can be stably adsorbed in the limit groove 34 under the action of the third anti-fooling magnet 33.

[0057] The first pusher cylinder 411 and the second pusher cylinder 412 respectively drive the first ejector rod 421 and the second ejector rod 422 to return to the initial position. The pressing cylinder 46 drives the pressing block 462 to rise. The magnet 7 at the frontmost position in the feeding channel 10 continues to move to the connection of the feeding channel 10 and the pusher channel 30 under the action of the first anti-fooling magnet 31, completing one replenishment. The magnet 7 in the magnetic material clamp 2 moves to the pusher channel 30 under the action of its own gravity and the second anti-fooling magnet 32, completing one replenishment.

[0058] The material transfer cylinder 52 drives the positioning suction head 521 to descend and abut against the magnet 7 in the limit groove 34. After the material transfer cylinder 52 moves in place, the second adsorption cylinder 53 drives the second suction plate 531 to descend and abut against the positioning suction head 521. The second suction plate 531 adsorbs the magnet 7 in the limit groove 34 at the grooved position of the positioning suction head 521. The first adsorption cylinder 35 drives the first suction plate 352 to descend, so that the first suction plate 352 no longer generates suction on the magnet 7 in the limit groove 34. The material transfer cylinder 52 drives the positioning suction head 521 to rise, and the magnet 7 at the grooved position of the positioning suction head 521 leaves the limit groove 34.

[0059] The servo motor 65 drives the lead screw 64 to rotate and drives the fixture 60 on the fixture plate 61 to move along the guide rail 63 to the limit groove 34 through the slider 62. The handling cylinder 51 drives the positioning suction head 521 to move above the fixture 60. The material transfer cylinder 52 drives the positioning suction head 521 to descend, and the magnet 7 on the positioning suction head 521 enters the grooved position of the fixture 60. The second adsorption cylinder 53 drives the second suction plate 531 to rise, so that the second suction plate 531 no longer generates suction on the magnet 7 in the fixture 60. After the material transfer cylinder 52 moves in place, the handling cylinder 51 drives the positioning suction head 521 to return to the initial position. Thus, one feeding operation is completed. The servo motor 65 continues to drive the lead screw 64 to rotate and drives another fixture 60 on the fixture plate 61 to move along the guide rail 63 to the limit groove 34 through the slider 62, and so on, until the feeding operation of all fixtures 60 is completed.
