Description

Technical Field

[0001] This invention relates to the field of radio frequency device processing technology, and specifically to a radio frequency device SMP anti-bias crimping fixture. Background Technology

[0002] With the current large-scale deployment of 5G and the trend towards miniaturization and high-density integration of RF modules, SMP connector crimping technology also needs to develop towards higher precision. Currently, the crimping process for SMP connectors in RF devices is mostly done manually or with simple tooling, and has the following drawbacks:

[0003] 1. High risk of misalignment: Manual crimping or tooling without precise positioning can easily lead to misalignment between the mounting holes of SMP connectors and RF devices, resulting in decreased signal transmission performance or even device failure.

[0004] 2. Unstable pressure: Manual operation makes pressure control difficult. Overpressure can damage the SMP device or the device to be crimped, while underpressure leads to an unstable connection. Therefore, there is an urgent need to design an anti-bias crimping fixture for RF devices to solve the above problems. Summary of the Invention

[0011] Furthermore, a support column is fixed to the top outer wall of the fixing block, and a pin is fixed to the bottom outer wall of the auxiliary plate, with the pin inserted into the inside of the support column.

[0012] Furthermore, a pressure sensor is installed on one side of the outer wall of the cylinder body 2, and a control host is fixed on one side of the outer wall of the mounting bracket. The pressure sensor and the control host are electrically connected by wires.

[0027] The present invention provides an SMP anti-bias crimping fixture for radio frequency devices. First, the radio frequency device is positioned by the positioning cavity inside the fixing block 3. Then, the connector body 20 is inserted into the guide hole 19 of the auxiliary plate 16 and the connector body 20 is pre-assembled with the radio frequency device.

[0029] In another embodiment of the present invention, a support column 21 is fixed to the top outer wall of the fixing block 3, and a pin 29 is fixed to the bottom outer wall of the auxiliary plate 16. The pin 29 is inserted into the interior of the support column 21. The center of the support column 21 has a pin hole that matches the pin 29. Both the pin 29 and the auxiliary plate 16 are conical in shape, making it easy to pull out the pin 29 when the auxiliary plate 16 is lifted. A pressure sensor 18 is installed on one side outer wall of the cylinder body 30, and a control host 17 is fixed on one side outer wall of the fixing bracket 2. The pressure sensor 18 and the control host 17 are electrically connected through a wire.

[0030] Working principle: In use, the radio frequency device is first positioned inside the positioning cavity of the fixed block 3. Then, the pin 29 at the bottom of the auxiliary plate 16 is inserted into the support column 21. Then, the connector body 20 is inserted into the guide hole 19 of the auxiliary plate 16, so that the connector body 20 and the radio frequency device are pre-assembled. The workpiece to be pressed is moved to the bottom of the pressing block 27 and the fixed block 3 is magnetically fixed by the magnetic suction module 14. The motor 31 drives the turntable 6 to rotate, so that the turntable 6 drives the piston 8 to reciprocate through the connecting rod 9. The movement of the piston 8 forces air into the cylinder 30, so that the air pressure pushes the piston 24 downward. The movement of the piston 24 drives the guide column 25 to press down, so that the guide column 25 drives the pressing block 27 to press the connector body 20 into place.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
