Description

Technical Field

[0001] This utility model relates to the technical field of magnetic feeding devices, and in particular to a ring magnet feeding device. Background Technology

[0002] Ring magnets are commonly used for magnetic positioning in wireless charging of mobile phones. During the assembly process of the ring magnet and the mobile phone, or during the process of attaching the ring magnet to Mylar, it is necessary to feed the ring magnet individually so that the subsequent process can remove the ring magnet one by one and perform the above-mentioned assembly or attachment actions.

[0003] In the prior art, such as the magnet feeding mechanism with application number 202211171901.8, the feeding part includes at least one set of feeding components, and the transmission part includes a first sliding component, a connecting plate and a first driving component. The connecting plate is driven by the first driving component to drive the worktable to move for feeding. However, it is only suitable for magnets of a specific thickness, has poor versatility, and cannot guarantee the stability of the magnet position during the feeding process. Utility Model Content

[0004] The purpose of this utility model is to provide a ring magnet feeding device, which feeds the ring magnets one by one by reciprocating movement of a support plate and a positioning plate. The support plate and the positioning plate are installed and positioned by embedding. When feeding ring magnets of different thicknesses, the positioning plate with positioning grooves of different depths can be quickly replaced, which can improve applicability.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a ring magnet feeding device, including a support frame, and:

[0006] A support plate, which is disposed on the bracket, has a guide hole penetrating its body, and there is a gap between the lower end of the support plate and the bracket.

[0007] The carrier abuts against the upper end of the support plate and has a storage hole for storing the annular magnet, which communicates with the guide hole.

[0008] The feeding mechanism includes a translation cylinder, a push plate, a support plate, a positioning plate, a lifting cylinder, and a magnetic attractor. The translation cylinder is mounted on the bracket. The push plate is located at the output end of the translation cylinder and has a receiving groove on its upper surface. The support plate and the positioning plate are inserted side by side and abut against each other into the receiving groove. When the push plate is driven to extend into the gap, the support plate and the positioning plate are sequentially located below the guide hole. The positioning plate has a positioning groove for embedding an annular magnet. The lifting cylinder is located at the lower end of the push plate. The magnetic attractor is located at the output end of the lifting cylinder and, after being driven upward, attracts the annular magnet located in the positioning groove.

[0009] As a further optimization, the magnetic suction component includes a vertical plate and a circular magnet. The vertical plate is disposed at the output end of the lifting cylinder, and the circular magnet is disposed at the upper end of the vertical plate for attracting the annular magnet located in the positioning groove.

[0010] As a further optimization, the lower end of the push plate is provided with a through hole that communicates with the receiving groove. The through hole is located below the positioning plate. The circular magnet is driven to extend into the through hole, which can shorten the distance between the circular magnet and the ring magnet, ensuring the adsorption effect and adsorption stability.

[0011] As a further optimization, the lower end of the positioning plate is provided with a clearance groove below the positioning groove. The circular magnet is driven to pass through the through hole and extend into the clearance groove, which can further shorten the distance between the circular magnet and the annular magnet.

[0012] As a further optimization, locking holes are provided on opposite sides of the positioning plate, and through holes are provided on the push plate that communicate with the receiving groove. The positioning plate is fixed in the receiving groove by bolts that pass through the through holes and extend into the locking holes, which can ensure the stability of the positioning plate.

[0013] As a further optimization, the upper surface of the support plate is flush with the upper surface of the positioning plate.

[0014] As a further optimization, the support plate includes a base plate and a pair of support ribs disposed on the upper surface of the base plate. The upper ends of the support ribs are flush with the upper surface of the positioning plate. The support ribs can support the annular magnet and reduce the contact friction area with the annular magnet.

[0015] As a further optimization, the lower part of the carrier is provided with a slot that communicates with the storage hole, and an insert plate is provided in the slot that can slide horizontally.

[0016] As a further optimization, the upper end of the support plate is provided with a limiting plate for positioning the lower end of the vehicle, which can ensure that the vehicle is accurately positioned on the support plate.

[0017] As a further optimization, the bracket is provided with an auxiliary limiting structure, which includes a side plate and a backing plate. A pair of side plates are disposed on the bracket, and the backing plate is locked onto the side plates to form a limiting cavity. The middle part of the carrier is embedded in the limiting cavity to improve the stability of the carrier on the bearing plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. A support and positioning plate are set in the receiving groove of the push plate. The ring magnets are fed one by one after being supported by the reciprocating movement of the support plate and the positioning plate. The support plate and the positioning plate are installed and positioned by embedding. When feeding ring magnets of different thicknesses, the positioning plate with positioning grooves of different depths can be quickly replaced, which improves the applicability.

[0020] 2. The ring magnet can be attracted and positioned by the magnetic attraction component during the feeding and translation process, ensuring the stability of the translation and facilitating docking with subsequent process equipment. Attached Figure Description

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figures 1 to 4As shown, a ring magnet feeding device includes a support 10, a bearing plate 20, a pushing mechanism 30, and a carrier 40. The bearing plate 20 is disposed on the support 10 and has a guide hole 201 penetrating its body. There is a gap 101 between the lower end of the bearing plate 20 and the support 10. The carrier 40 abuts against the upper end of the bearing plate 20 and has a storage hole 401 for storing ring magnets 100, which communicates with the guide hole 201. The pushing mechanism 30 includes a translation cylinder 31, a push plate 32, a support plate 331, a positioning plate 332, a lifting cylinder 341, and a magnetic suction component 342. The translation cylinder 31 is disposed on the support 10, and the push plate 32 is disposed at the output end of the translation cylinder 31, and its upper end surface is provided with a container. The receiving groove 320, the support plate 331 and the positioning plate 332 are embedded in the receiving groove 320 side by side and abut against the side wall of the receiving groove 320. Preferably, the upper end face of the support plate 331 is flush with the upper end face of the positioning plate 332 and the upper end face of the push plate 32. When the push plate 32 is driven to extend into the gap 101, the support plate 331 and the positioning plate 332 are located below the guide hole 201 in sequence. The positioning plate 332 is provided with a positioning groove 3320 for embedding the ring magnet 100. The lifting cylinder 341 is set at the lower end of the push plate 32. The magnetic suction element 342 is set at the output end of the lifting cylinder 341 and is driven to move upward and adsorb the ring magnet 100 located in the positioning groove 3320.

[0029] In this invention, multiple ring magnets 100 are stacked and placed in the storage hole 401 of the carrier 40. The carrier 40 is placed on the support plate 20. The ring magnets 100 in the storage hole 401 fall into the guide hole 201 due to gravity. The support plate 331 or positioning plate 332 on the push plate 32 is located below the guide hole 201. The lowest ring magnet 100 falls onto the support plate 331 or positioning plate 332. Specifically, when the support plate 331 is below the guide hole 201, the lowest ring magnet 100 falls onto the support plate 331. When the push plate 32 is driven to translate, the support plate 331 and positioning plate 332 translate synchronously. Because the lowest ring magnet 100 is supported by the support plate 331 and remains at least partially or completely within the guide hole 201, it cannot translate until the positioning plate 332 is positioned within the guide hole 201. The lower rear positioning groove 3320 of 1 is connected to the guide hole 201 (during this process, the lowest ring magnet 100 moves relative to the support plate 331). The lowest ring magnet 100 falls into the positioning groove 3320, that is, falls onto the positioning plate 332. After being driven, the magnetic suction member 342 moves upward and magnetically attracts the ring magnet 100, which can ensure the stability of the ring magnet in the positioning groove 3320. When the push plate 32 is driven to move in the opposite direction, the ring magnet in the positioning groove 3320 is no longer blocked by the inner wall of the guide hole 201, so it can follow the positioning plate 332 to extend out of the gap 101. During the process of the positioning plate 332 extending out of the gap 101, the support plate 331 gradually extends into the gap 101 to support the ring magnet 100 in the guide hole 201. The ring magnet 100 extending out of the gap 101 can be removed by external equipment (after the magnetic suction member 342 is reset). By driving the push plate 32 through the translation cylinder 31 to move the support plate 331 and the positioning plate 332 back and forth, the ring magnets 100 can be fed one by one. The ring magnets 100 are attracted by the magnetic attractant 342 in the positioning groove 3320, which can realize the stability of the ring magnets 100 during the translation of the positioning plate 332.

[0030] This invention provides a receiving groove 320 on the push plate 32 for positioning the support plate 331 and the positioning plate 332. The support plate 331 and the positioning plate 332 are driven to reciprocate to support the ring magnet 100 during feeding and allow the ring magnet 100 to fall into the positioning groove 3320 one by one for feeding. The support plate 331 and the positioning plate 332 are installed and positioned by embedding. When feeding ring magnets of different thicknesses, the positioning plate 332 with different depth positioning grooves 3320 can be quickly replaced, which improves the applicability of the device.

[0031] It should be noted that when the support plate 20 is locked onto the bracket 10, it is convenient to replace it. When it is necessary to supply magnets with other contour structures, such as bar magnets, the support plate with a bar-shaped guide hole, the carrier with a bar-shaped storage hole, and the positioning plate with a bar-shaped positioning groove can be replaced. By uniformly replacing the positioning plate, support plate, and carrier, magnets with different contours and thicknesses can be supplied.

[0032] For the annular magnet 100, the magnetic suction component 342 includes a vertical plate 3421 and a circular magnet 3422. The vertical plate 3421 is located at the output end of the lifting cylinder 341, and the circular magnet 3422 is located at the upper end of the vertical plate 3421 to attract the annular magnet 100 located in the positioning groove 3220. The structure of the circular magnet 3422 is convenient for it to be installed on the vertical plate 3421, and also allows it to have a large range of action to attract the annular magnet 100.

[0033] Preferably, the lower end of the push plate 32 is provided with a through hole 3200 that communicates with the receiving groove 320. The through hole 3200 is located below the positioning plate 332. The circular magnet 3422 is driven to extend into the through hole 3200, so that it can be attracted to the ring magnet 100 at a closer distance, ensuring the stability of the ring magnet 100 when it moves in the positioning groove 3220.

[0034] Furthermore, such as Figure 5 As shown, the lower end of the positioning plate 332 is provided with a clearance groove 3321 below the positioning groove 3320. The circular magnet 3422 is driven to pass through the through hole 3200 and extend into the clearance groove 3321, so that it can be closer to the annular magnet 100 for adsorption and positioning.

[0035] Based on the fact that the circular magnet 3422 can extend into the clearance groove 3321, the positioning plate 332 is provided with locking holes 3322 on both sides of the opposite side, and the push plate 32 is provided with through holes 3201 communicating with the receiving groove 320 on both sides of the opposite side. The positioning plate 332 is fixed in the receiving groove 320 by bolts that pass through the through holes 3201 and extend into the locking holes 3322, which can prevent the magnetic suction component 342 from lifting the positioning plate 332 under the drive of the lifting cylinder 341, thus avoiding unstable installation.

[0036] like Figure 6 As shown, in another embodiment of this utility model, the support plate 331 includes a base plate 3311 and a pair of support ribs 3312 disposed on the upper surface of the base plate 3311. The upper ends of the support ribs 3312 are flush with the upper surface of the positioning plate 332. The base plate 3311 and the positioning plate 332 abut against each other side by side, and the pair of support ribs 3312 abut against and support the annular magnet 100 located in the guide hole 201. Under the premise of achieving stable support, the friction surface with the annular magnet 100 can be reduced.

[0037] In addition, the lower part of the carrier 40 is provided with a slot 402 that communicates with the storage hole 401. A plate 41 is provided in the slot 402 that can slide horizontally, so that the carrier 40 can carry multiple stacked ring magnets 100. The ring magnet 100 at the bottom abuts against the plate 41. After the carrier 40 is placed on the support plate 20, the plate 41 is removed from the slot 402, and the ring magnet 100 in the storage hole 401 falls into the guide hole 201.

[0038] For example Figure 1 and Figure 2 As shown, preferably, the upper end of the support plate 20 is provided with multiple limiting plates 21 for positioning the lower end of the carrier 40, which can ensure the stability of the carrier 40 and ensure that the material storage hole 401 and the material guide hole 201 are accurately connected.

[0039] Furthermore, the bracket 10 is provided with an auxiliary limiting structure 50, which includes a side plate 51 and a stop plate 52. A pair of side plates 51 are disposed on the bracket 10, and the stop plate 52 is locked onto the side plates 51 to form a limiting cavity 510. The middle part of the carrier 40 is embedded in the limiting cavity 510, which can further ensure the stability of the carrier 40. Since one end of the insert plate 41 protrudes from the carrier 40 (to facilitate the removal of the insert plate 41), the limiting cavity 510 can be formed by first positioning the carrier 40 between a pair of side plates 51 and then locking the stop plate 52. Then the side wall of the carrier 40 abuts against the bracket 10, the side plate 51 and the stop plate 52 respectively, which has good stability.

[0040] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
