Technical Field

[0001] This invention relates to the technical field of positioning devices and methods before injection molding of cylindrical FPCs, and in particular to a positioning device and method for cylindrical FPCs before injection molding. Background Technology

[0002] Currently, headphones, as an electroacoustic device, are closely linked to people's daily life and work. Whether at home, outdoors, or in important meetings or hearing tests, headphones are readily available and have become a symbol of people's portable audio equipment.

[0003] Bluetooth headsets apply Bluetooth technology to hands-free headsets, freeing users from the hassle of annoying wires and allowing them to easily make calls in various ways. They can operate a computer while maintaining a call. In addition, the most widespread application of Bluetooth technology in daily life is in Bluetooth-enabled mobile phone calling devices, such as Bluetooth headsets. Bluetooth also makes driving safer.

[0004] The power conversion chip of existing Bluetooth headsets generally includes an FPC, a power chip body, and a cylindrical shell with open ends. The power chip body is located inside the cylindrical shell, one end of the FPC extends into the cylindrical shell and connects to the power chip body, and the other end of the FPC extends out of the cylindrical shell.

[0005] Currently, power conversion chips require injection molding. Before injection molding, they need to be manually placed into the placement slot of the mold core. However, the FPC does not fit well with the placement slot, resulting in increased thickness after injection molding, which affects the quality of the product.

[0006] Therefore, in this patent application, the applicant has carefully studied a positioning device and method for cylindrical FPC before injection molding to solve the above problems. Summary of the Invention

The output end of the second driving cylinder is connected to the lower end of the connector to drive the clamping block closer to or further away from the first groove through the connector.

[0017] As a preferred embodiment, the lower end face of the clamping block is recessed with a groove, and the upper end of the connector is formed with a protrusion. The clamping block is connected to the connector, and the protrusion is adapted to fit into the groove.

[0018] As a preferred embodiment, the upper end surface of the placement block is further recessed with a sliding groove for displacing the clamping block, the slot is connected to the sliding groove, and the sliding groove is connected to the first groove and the second groove respectively;

[0019] The clamping block is slidably mounted in the groove, and the end face of the clamping block facing away from the first groove is connected to the inner wall of the clearance groove through an elastic reset member.

[0020] As a preferred embodiment, the lower end face of the placement block is recessed upward with a relief groove, the upper end of the relief groove is connected to a sliding groove, and the upper end of the connector is fitted into the slot through the relief groove and the sliding groove in sequence.

[0021] As a preferred embodiment, it also includes a control switch mounted on the rack, the control switch being connected to the main control unit.
