[0032] Specifically, when the bending operation is performed, the electronic components are accurately placed on the fixed mold 7 and the movable mold 4, then the output end of the hydraulic cylinder 6 starts to work, pushing the upper pressing mold 207 to move downward, since the upper pressing mold 207 is connected with the protective frame 204, the protective frame 204 will also move downward synchronously, at the same time, the output end of the air cylinder 202 also moves downward and gradually extends, in this process, the air cylinder 202 gradually fills with gas, when the rubber block 206 at the lower end of the protective frame 204 tightly fits on the upper end of the movable mold 4 and the fixed mold 7, it can protect the electronic components to a certain extent, avoiding damage to the electronic components by impact force during the bending process, at this time, the hydraulic cylinder 6 continues to exert force, pushing the upper pressing mold 207 to move further downward, so that the spring 208 inside the protective frame 204 is stretched, and the guide rod 201 also slides inside the protective frame 204, playing a guiding role, at this time, the protective frame 204 remains in a stationary state on the fixed mold 7 and the movable mold 4, while the upper pressing mold 207 continues to move downward, starting to bend the pins of the electronic components;

[0033] When the pin bending is completed, the output end of the hydraulic cylinder 6 starts to reverse, driving the upper pressing mold 207 to rise upward, when the upper pressing mold 207 rises to a certain height, the protective frame 204 will release the protection state of the electronic components on the movable mold 4 and the fixed mold 7, and then move upward together with the upper pressing mold 207, at this time, the output end of the air cylinder 202 retracts, the gas originally filled in the air cylinder 202 is squeezed, the one-way valve 11 will prevent the gas from being discharged, so that these gases can only be blown out from the air jet plate 205 through the connecting pipe 203, the strong airflow acts on the electronic components on the movable mold 4 and the fixed mold 7, blowing them off the processing table 3, which is convenient for collection, the whole operation process is convenient and efficient.

[0034] Referring to Figures 1-3 , one side of the inside of the processing table 3 is fixedly provided with an electric telescopic rod 9, the output end of the electric telescopic rod 9 is fixedly provided with a movable mold 4, the inside of the processing table 3 is fixedly provided with guide columns 8 at the front and rear ends, the movable mold 4 is slidably arranged outside the two guide columns 8, the upper end of the processing table 3 is fixedly provided with a fixed mold 7 away from the electric telescopic rod 9, and a plurality of supporting legs 5 are fixedly arranged at the lower end of the processing table 3;

[0035] Specifically, when different sizes of electronic components need to be processed, the output end of the electric telescopic rod 9 will extend, pushing the movable mold 4 to move along the guide column 8 to the fixed mold 7, the guide column 8 ensures the stability and accuracy of the movement of the movable mold 4, thereby adjusting the distance between the two to adapt to electronic components of different sizes, expanding the use range of the equipment, and the supporting legs 5 will provide stable support.

[0036] Working principle: when adapting to different sizes of electronic processing components, the output end of the electric telescopic rod 9 extends, pushes the movable mold 4 to move along the guide column 8, so that the movable mold 4 moves towards the fixed mold 7, facilitating the processing of electronic components of different sizes;

[0037] When it is necessary to bend the pins of the electronic components, the electronic components are first placed on the fixed mold 7 and the movable mold 4, and then the equipment is started. The moving plate 12 will move under the drive of the electric guide rail 10. When it moves to the appropriate position, the output end of the hydraulic cylinder 6 starts, which will push the upper pressing mold 207 to move downward. The downward movement of the upper pressing mold 207 will synchronously drive the protective frame 204 to move downward. The output end of the air cylinder 202 will synchronously move downward, so that it gradually extends, and then the air cylinder 202 gradually fills with gas. When the rubber block 206 at the lower end of the protective frame 204 is attached to the upper end of the movable mold 4 and the fixed mold 7, the protection of the electronic components is realized. The hydraulic cylinder 6 will continue to push the upper pressing mold 207 to move downward, so that the spring 208 is stretched, and the guide rod 201 slides inside the protective frame 204.

[0038] At this time, the protective frame 204 is stationary on the fixed mold 7 and the movable mold 4, while the upper pressing mold 207 continues to move downward. The downward movement of the upper pressing mold 207 will start to bend the pins. When the bending is completed, the output end of the hydraulic cylinder 6 drives the upper pressing mold 207 to rise. When the upper pressing mold 207 rises to a certain position, the protective frame 204 will release the protection of the electronic components on the movable mold 4 and the fixed mold 7, so that the protective frame 204 moves upward with the upper pressing mold 207. At this time, the output end of the air cylinder 202 retracts, and the gas inside will be squeezed and sprayed from the jet plate 205 through the connecting pipe 203, realizing the blowing of the electronic components on the movable mold 4 and the fixed mold 7, so that they fall from the processing table 3 and are collected.
