Description

Technical Field

[0001] This utility model relates to the field of magnetic ring gripping technology, and in particular to a magnetic ring clamping fixture for an automatic magnetic ring attaching device for mobile phone cases. Background Technology

[0002] Phone cases are peripheral products used to protect mobile phones. In daily life, mobile phones are usually equipped with a phone case. In order to accommodate magnetic wireless charging after the phone is equipped with a phone case, a magnetic ring is installed inside the phone case. Therefore, during the production process of phone cases, it is necessary to assemble the corresponding magnetic ring inside the phone case.

[0003] In the process of assembling the magnetic ring into the phone case, a fixture is needed to hold the magnetic ring, especially after the protective film has been removed. Because the magnetic ring consists of a circular ring and a magnetic stripe, existing fixtures for holding circular components typically use multiple jaws or a single chuck. Using jaws or a chuck makes the fixture design more complex, requiring additional space for the jaws to unfold; furthermore, it prevents the simultaneous and precise gripping of the magnetic stripe, necessitating an extra gripping step and hindering production efficiency.

[0004] Therefore, it is necessary to optimize the structure of existing magnetic ring clamping fixtures. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a magnetic ring clamping fixture for an automatic magnetic ring attaching device for mobile phone cases.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A magnetic ring clamping fixture for an automatic magnetic ring applicator for mobile phone cases includes a base plate and a pusher mounted on the base plate. The pusher's push head points vertically downwards. The base plate has a top plate and a bottom plate at its bottom. The four corners of the top plate and the bottom plate are connected by guide posts. A movable plate is provided between the top plate and the bottom plate. The bottom of the movable plate has a first magnetic attractor for attracting the magnetic ring and a second magnetic attractor for attracting the magnetic strip. The bottom plate has a through groove for accommodating the magnetic ring and the magnetic strip. The shape of the through groove corresponds to the shape of the magnetic ring and the magnetic strip. The first magnetic attractor and the second magnetic attractor are both aligned with the through groove and can be inserted into the through groove. The pusher's push head is connected to the movable plate and drives the movable plate to move vertically. The bottom plate and the top plate are both made of non-ferromagnetic metal.

[0008] Preferably, the guide posts pass through the four corners of the movable plate, allowing the movable plate to move along the extension direction of the guide posts.

[0009] Preferably, the actuator is a cylinder.

[0010] Preferably, the base plate has a boss, and the through groove is provided on the boss.

[0011] Preferably, the first and second magnetic attractors are magnets or ferromagnetic metals.

[0012] By adopting the above solution, this utility model directly sets up a first magnetic suction body and a second magnetic suction body with shapes corresponding to the magnetic ring and magnetic strip to pick up the magnetic ring and magnetic strip, eliminating the need for complex structure designs of clamps or chucks, and can hold the magnetic ring and magnetic strip together. At the same time, the through groove can pre-position the positional relationship of the magnetic ring and magnetic strip, ensuring that the clamping positional relationship does not change, which is beneficial for the subsequent installation of the magnetic ring and magnetic strip to the mobile phone case.

[0020] like Figures 1 to 4 As shown in this embodiment, a magnetic ring clamping fixture for an automatic magnetic ring applicator for mobile phone cases includes a base plate 1 and a pusher 2 mounted on the base plate 1. The base plate 1 is fixedly mounted on the moving mechanism of the automatic magnetic ring applicator for mobile phone cases. The pusher 2 is a cylinder, and the pushing head of the pusher 2 is vertically downward. A top plate 3 and a bottom plate 4 are provided at the bottom of the base plate 1. The four corners between the top plate 3 and the bottom plate 4 are connected by guide posts 5. A movable plate 6 is provided between the top plate 3 and the bottom plate 4. The bottom of the movable plate 6 is provided with a first... A magnetic attractor 7 and a second magnetic attractor 8 for attracting magnetic stripe 102 are provided. The base plate 4 is provided with a through groove 9 that can accommodate magnetic ring 101 and magnetic stripe 102. The shape of the through groove 9 corresponds to the shape of magnetic ring 101 and magnetic stripe 102. The first magnetic attractor 7 and the second magnetic attractor 8 are both facing the through groove 9 and can be inserted into the through groove 9. The pushing head of the pusher 2 is connected to the movable plate 6 and drives the movable plate 6 to move in the vertical direction. The base plate 4 and the top plate 3 are both made of non-ferromagnetic metal, and the first magnetic attractor 7 and the second magnetic attractor 8 are magnets or ferromagnetic metals.

[0021] In this embodiment, a first magnetic chuck 7 and a second magnetic chuck 8, whose shapes correspond to the magnetic ring 101 and magnetic strip 102, are directly set up to pick up the magnetic ring 101 and magnetic strip 102, eliminating the need for complex structures such as grippers or chucks. They can hold the magnetic ring 101 and magnetic strip 102 together. At the same time, the through groove 9 can be used to pre-position the positional relationship between the magnetic ring 101 and magnetic strip 102, ensuring that the positional relationship does not change and facilitating the subsequent installation of the magnetic ring 101 and magnetic strip 102 onto the mobile phone case.

[0022] During the specific clamping operation, the substrate 1 is first moved to the material (i.e., the magnetic ring 101 and the magnetic strip 102 are attached together on a base film 100), and then moved down. The through groove 9 on the base plate 4 is first aligned with the magnetic ring 101 and the magnetic strip 102, so that the upper half of the magnetic ring 101 and the magnetic strip 102 are submerged in the through groove 9. It should be noted that the base film 100 on the material is fixed. Subsequently, the pusher 2 operates, pushing the push head downwards, causing the movable plate 6 to move down. The tips of the first magnetic 7 and the second magnetic 8 are inserted into the through slot 9, respectively, and finally make contact with the magnetic ring 101 and the magnetic strip 102. Relying on the attraction force between the first magnetic 7, the second magnetic 8 and the magnetic ring 101 and the magnetic strip 102, the magnetic ring 101 and the magnetic strip 102 are attracted. As the moving mechanism of the automatic magnetic ring attaching device moves the entire device onto the phone case, and the magnetic ring 101 and the magnetic strip 102 adhere to the adhesive on the phone case, the pusher 2 retracts, leaving the magnetic ring 101 and the magnetic strip 102 on the phone case. This completes one gripping operation. Of course, this is just one example of the gripping operation and is not limited to its application only when the magnetic ring 101 and the magnetic strip 102 are bonded to the phone case.

[0023] Furthermore, in order to make the movable plate 6 move up and down more smoothly, the guide posts 5 in this embodiment pass through the four corners of the movable plate 6 respectively, so that the movable plate 6 moves along the extension direction of the guide posts 5. In this way, the guide posts 5 can act as guides for the movable plate 6, so that the movable plate 6 is not prone to swaying during the movement. The movable plate 6 or the guide posts 5 need to be designed as non-magnetic materials.

[0024] Furthermore, in order to make other parts of the base plate 4 thinner and reduce the amount of material and weight, the base plate 4 in this embodiment is provided with a boss 10 and the through groove 9 is provided on the boss 10. In this way, only the through groove 9 is made thicker, while other places can be made thinner, thus achieving the design requirements.

[0025] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
