Example

[0021] As attached Figure 1 Appendix Figure 2 and attached Figure 3As shown, a pin cutting machine for manufacturing electronic components includes a housing 1. The top of the housing 1 is provided with a feeding port 2. A support plate 3 and a mounting plate 4 are installed on the inner side of the top of the housing 1. The support plate 3 and the mounting plate 4 are respectively located on both sides of the feeding port 2. An adjustable support assembly is installed at the bottom of the housing 1. The adjustable support assembly includes an electric telescopic rod 12 and a support block 13. The lower end of the electric telescopic rod 12 is fixedly installed at the bottom of the housing 1, and the extended end is fixedly connected to the lower side of the support block 13. The support block 13 is located between the support plate 3 and the mounting plate 4, and is located below the feeding port 2. Electronic components are passed through the inner side of the feeding port 2. The pins on one side of the electronic components are supported on the upper side of the support block 13. The electric telescopic rod 12 is extended and retracted by a control switch outside the housing 1 to adjust the height of the electronic components and adjust the pin cutting length.

[0022] To accurately determine the pin cutting length, see attached... Figure 1 and attached Figure 3 As shown, an infrared fixed-length component is installed between the adjustable support assembly and the support plate 3. The infrared fixed-length component includes a modulation light emitting unit 24 and a receiving unit 26. A mounting plate 23 is installed on the side of the support plate 3 away from the mounting plate 4. The modulation light emitting unit 24 passes through and is installed inside the mounting plate 23. An L-shaped mounting plate 25 is installed on the lower side of the support block 13. The receiving unit 26 is installed on the upper side of the bottom plate of the L-shaped mounting plate 25 and is aligned with the modulation light emitting unit 24. During the extension and retraction of the electric telescopic rod 12, the modulation light emitting unit 24 continuously emits multiple sets of light beams, and the reflected light is received by the receiving unit 26 and converted into an electrical signal, which is sent to the control terminal. The control terminal analyzes the round-trip time difference of the light beams to calculate the distance. When the calculated distance reaches the cutting requirement, the control terminal controls the electric telescopic rod 12 to stop extending and retracting, and fixes the position of the support block 13. At this time, the cutting length adjustment of the electronic component pin is completed.

[0023] To ensure the stability of electronic components during cutting, as shown in the attached document...

The electric telescopic rod 7 is opened by a control switch on the outside of the housing 1, and the electric telescopic rod 7 extends to push the clamping plate 8 toward the electronic components. A pressure sensor is installed at the connection between the electric telescopic rod 7 and the clamping plate 8 to transmit the pressure to the control terminal. After the control terminal detects that the pressure value has reached the highest threshold, it controls the electric telescopic rod 7 to stop moving and clamp the electronic components. A protective pad 9 is installed on the side of the clamping plate 8 near the support plate 3 to prevent the clamping plate 8 from damaging the electronic components.
