[0002] The probe card is a test interface that mainly tests bare chips. It connects the test machine and the chip, and tests the chip parameters by transmitting signals. The probes on the probe card directly contact the pads or bumps on the chip to bring out the chip signals, and then cooperate with peripheral test instruments and software control to achieve the purpose of automated measurement. The probe card is used before the IC is packaged. The bare chip system is tested with probes to screen out defective products and then proceed to the subsequent packaging process. In order to facilitate the use of probes with circuit test instruments, the straight probes produced need to be bent. However, the current processing and bending of the probes is mainly done by workers using tools to manually bend the probes because they are small and easily damaged. As a result, the easily damaged and broken probes can easily injure the workers during manual bending, so a probe bending device is needed. Summary of the invention
