Description

Technical Field

[0001] The utility model relates to the technical field of potentiometer processing, in particular to a pin bending tool for assembling a coding potentiometer. Background Art

[0002] Pin bending tools play a crucial role in the assembly of encoder potentiometers. As precision electronic components, encoder potentiometers are widely used in a variety of electronic devices, particularly in automotive electronic control systems, industrial automation equipment, and computer hardware. These devices demand extremely high precision and stability. The pin bending tool's primary functions are: 1) Ensuring pin stability: During encoder potentiometer assembly, the pins must be securely fixed to the circuit board to ensure a reliable and stable electrical connection. By precisely bending the pins, the pin bending tool facilitates insertion and soldering onto the PCB, reducing the risk of pins falling off due to vibration or temperature fluctuations. 2) Improving assembly efficiency: The pin bending tool can automatically or semi-automatically perform the pin bending operation, significantly improving assembly efficiency. This is particularly important for production lines that require high-volume assembly of encoder potentiometers, significantly shortening production cycles and reducing costs. 3) Maintaining pin spacing: The pins of encoder potentiometers must be aligned with each other, maintaining a certain spacing to prevent interference. The pin bending tool can accurately control the position and angle of the pin bending, thereby ensuring that the spacing between the pins meets the design requirements and ensuring the overall performance and stability of the circuit board.

[0003] Existing pin bending tools for assembling encoder potentiometers have shortcomings. First, they cannot achieve bidirectional bending, which is not suitable for assembling encoder potentiometers that require bidirectional pin bending. Second, their complex structure does not allow for convenient manual operation. Therefore, there is a need to optimize and improve existing pin bending tools for assembling encoder potentiometers.
