Description

Technical Field

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0033] The specific embodiment of the present invention provides a Halbach magnet assembly feeding device, combined with the attached Figure 1As shown, it mainly includes a jig circulation device 1, a jig grasping and placing device 2, a positioning and conveying mechanism 3 and a loading assembly 4, wherein the jig circulation device 1 is used to realize the circulation of jigs between various devices, the positioning and conveying mechanism 3 is arranged on one side of the jig circulation device 1, the loading assembly 4 is arranged on one side of the positioning and conveying mechanism 3, and the jig grasping and placing device 2 is arranged between the positioning and conveying mechanism 3 and the jig circulation device 1; the jig grasping and placing device 2 is used to grasp the jig on the jig circulation device 1 and place it on the positioning and conveying mechanism 3, or to grasp the jig on the positioning and conveying mechanism 3 and place it on the jig circulation device 1, and the loading assembly 4 is used to absorb and arrange the magnets on the jig on the positioning and conveying mechanism 3.

[0034] Specifically, the feeding assembly 4 in the present application includes a silo plate 5, a cylinder kit 6, a cover plate 7 and a suction head 8, and is combined with the attached Figure 1 and 2As shown, one end of the positioning and conveying mechanism 3 extends to below the gripping and placing position of the fixture gripping and placing device 2, and the other end extends to the silo plate 5. The silo plate 5 is made of inorganic polymer material. The positioning and conveying mechanism 3 can convey the fixture placed by the fixture gripping and placing device 2 to one side of the silo plate 5 to wait for the loading component 4 to load the material, wherein the silo plate 5 is provided with a suction trough 9, a material channel 10 and a material guide portion 11, the material channel 10 is a channel for magnet arrangement for loading, and the magnets are sucked into one and arranged in a straight line in the material channel 10, and the material channel 10 is connected with the suction trough 9, so that the material channel 10 is connected with the suction trough 9. The magnet can enter the suction trough 9. The magnet inside the suction trough 9 is the magnet to be loaded. The guide part 11 is used to introduce the magnet from the material channel 10 into the suction trough 9, and provide a force for the magnet material inside the material channel 10 to move to the inside of the suction trough 9. The cover plate 7 is set on the silo plate 5. The cover of the cover plate 7 can form a hole-shaped magnet channel for the material channel 10. The cover plate 7 has a suction port 12 corresponding to the suction trough 9. The suction port 12 can be used for the suction head 8 to extend into for suction. The cylinder kit 6 is set on the cover plate 7. The cylinder kit 6 is for the suction head 8 and The magnet to be loaded provides power, and the cylinder kit 6 can push the magnet to move to the fixture on the positioning and conveying mechanism 3 on one side. The suction head 8 is set on the cylinder kit 6. The cylinder kit 6 drives the suction head 8 to extend into the suction port 12. The suction head 8 attracts the magnet. At this time, the cylinder kit 6 pushes the suction head 8 and the magnet to move.

[0035] The Halbach magnet assembly and feeding equipment mentioned above can be used to complete the Halbach magnet assembly, and manual participation is no longer required. Mechanized feeding will not cause the problem of low efficiency when manpower is tired. At the same time, the feeding path is fixed, and there will be no accidental feeding failure.

[0036] The number of the feeding components 4 is two or more, and the fixture grasping and placing device 2 and the feeding components 4 are arranged one by one. In the specific embodiment disclosed in the present application, there are two. Since the magnetic poles of adjacent magnets in the Halbach magnet assembly are perpendicular, the feeding is carried out by attaching Fig.11The three magnets shown in the figure are used to illustrate that in the present application, a group of feeding components 4 are used to feed two magnets on one side in opposite directions, and then another group of feeding components 4 are used to feed one magnet on the other side, or one magnet is fed first and then two magnets. The purpose of feeding separately is to avoid the problem of mutual attraction of the same-direction magnetic poles in the suction groove 9, which leads to the failure of feeding. Fig.11 and attached Figure 1 , among which No. 1 loading machine is Figure 1 The material components 4 on both sides of the positioning and conveying mechanism 3 at the left position, and the No. 2 loader is the material loading components 4 on both sides of the positioning and conveying mechanism 3 at the right position.

[0037] In the specific embodiment of the present application, the material channel 10 includes a first material channel 13 and a second material channel 14.

For this reason, a push rod groove 16 is arranged on the second material channel 14 to communicate with the suction groove 9. A second receiving groove 17 is arranged at the other side of the push rod groove 16 opposite to the second material channel 14. The material guiding part 11 in the present application includes a pulling magnet 18 and a pushing cylinder 19, the pulling magnet 18 is arranged in the first receiving groove 15 and the second receiving groove 17, the magnetic poles in the first receiving groove 15 and the second receiving groove 17 facing the first material channel 13 and the second material channel 14 are in opposite directions from the magnetic poles of the first material channel 13 and the second material channel 14 facing the first receiving groove 15 and the second receiving groove 17, ensuring that the magnets in the first receiving groove 15 and the second receiving groove 17 can attract the magnets of the first material channel 13 and the second material channel 14, so as to provide a physical force to drive the magnets of the first material channel 13 and the second material channel 14 to move, combined with the attached Figure 2 The pushing cylinder 19 is arranged on the silo plate 5, and the cylinder rod of the pushing cylinder 19 extends into the push rod groove 16, and can push the magnet in the push rod groove 16 into the suction groove 9. It is worth noting that the pushing cylinder 19 pushes the material after the suction head 8 extends into the suction groove 9.

[0038] In order to improve the efficiency of loading, the number of loading components 4 is designed to be two, which are respectively arranged on both sides of the positioning and conveying mechanism 3, and the two loading components 4 are staggered, so that loading can be performed from both sides of the fixture at the same time, which doubles the efficiency.

[0039] In order to realize loading, the cylinder kit 6 in this application is the main loading power source, wherein the cylinder kit 6 includes a first cylinder 20, a second cylinder 21, a third cylinder 22 and a fourth cylinder 23.

The fourth cylinder 23 is arranged on the limit push rod 24, and the limit push rod 24 can extend into the suction port 12 and the suction groove 9 toward the local position of the silo plate 5, and a receiving groove 25 is arranged on its end surface, and this receiving groove 25 is used to accommodate magnets. For this purpose, the receiving groove 25 is two magnets corresponding to the first material channel 13 and the second material channel 14 for feeding materials, and a slide groove 26 is arranged on the limit push rod 24, and the slide groove 26 is connected with the receiving groove 25. A suction head 8 is arranged on the movable end of the fourth cylinder 23, and the suction head 8 can slide along the slide groove 26 under the drive of the fourth cylinder 23, and the suction head 8 extends into the material storage tank 12 as shown in the attached figure. Figure 4 In the position shown in the figure, the suction head 8 and the receiving groove 25 just form a space for receiving the magnet, and the bottom of the suction head 8 is close to the magnet. The suction head 8 is made of a material that can be attracted by the magnet, while the limit push rod 24 is made of a material that will not be attracted, such as a copper alloy. The suction head 8 can be moved upward and separated from the receiving groove 25 by the fourth cylinder 23, so that it is far away from the magnet, and it can be attracted by the magnet. In order to ensure that the magnet in the first material channel 13 can be separated in the suction groove 9, the first cylinder 20 can be directly extended when pushing out the magnet in the suction groove 9, so that the magnet is pushed out horizontally from the suction groove 9 to the fixture position.
