Description

Technical Field

[0001] The utility model belongs to the field of coil processing devices, in particular to a vacuum adsorption conversion mechanism. Background Art

[0002] Linear vibration motors are usually used in mobile phones, tablets, game controllers, smart wearable products, etc. These products usually have certain requirements on the thickness and weight of the products, so higher requirements are also placed on the thickness and weight of linear vibration motors.

[0003] In order to solve this problem, parallel coils have appeared in the prior art. This kind of coil can reduce the thickness of the product when used in the motor. However, since the coils wound by most winding machines are usually plum blossom-shaped, the plum blossom-shaped coils need to be processed again to become parallel coils. Currently, this processing is usually done manually. The plum blossom-shaped coils are manually taken out from the fixture, the product is bent into a parallel shape, and then the coils are placed in the fixture. In this process, the switching of coils in different fixtures is done manually, and it is a multi-manual operation, which is prone to errors, resulting in equipment misoperation due to incorrect use of the fixture in the later process. Utility Model Content

In the present application, when the coil is deformed, the coil may fall off the positioning core under the action of stress during the deformation process. The anti-falling limiting member can appropriately press and block the coil for deformation, thereby preventing the coil from escaping from the deformation structure; before the coil is deformed, the bent component is used to handle the connecting wire of the coil, thereby preventing the connecting wire from being broken or loosened from the coil body during the deformation process.
