By installing two feeding mechanisms on the side walls of the two punching machines close to the discharge platform, the two feeding mechanisms can respectively transport the left double door ring and the right double door ring to the two punching machines, thereby enabling the two punching machines to simultaneously stamp the left double door ring and the right double door ring, further improving product work efficiency.

[0018] 2. By fixing the two ground rails on the ground, there is a distance between the two ground rails, and the two ground rails are allowed to extend safely toward the loading robot, so that the ground can support the two ground rails; by connecting the four rollers to the bottom of the platform car, and passing the two ground rails through the four rollers respectively, so that the two ground rails support the platform car through the four rollers, so that the platform car can move along the two ground rails to the loading robot, so as to avoid the platform car from deflecting during movement, thereby improving the stability of the platform car.

[0019] 3. When the left double door ring or the right double door ring moves between the first pair of centering plates and the second pair of centering plates, the first rotating shaft and the second rotating shaft are rotated at the same time, so that the first rotating shaft drives the first belt to move through the first pulley, and the second rotating shaft drives the second belt to move through the second pulley, thereby causing the first pair of centering plates and the second pair of centering plates to move relative to each other, thereby realizing the straightening of the left double door ring and the right double door ring to improve the position accuracy of the left double door ring and the right double door ring.

[0020] 4. By installing the first guide rail on the side wall of the first support beam, connecting the first slider with the first movable plate, and passing the first guide rail through the first sliding groove of the first slider, the first movable plate can be moved along the first guide rail through the first slider to avoid the first movable plate from deviating during movement, thereby improving the stability of the movement of the first movable plate; by installing the second guide rail on the side wall of the second support beam, connecting the second slider with the second movable plate, and passing the second guide rail through the second sliding groove of the second slider, the second movable plate can be moved along the second guide rail through the second slider to avoid the second movable plate from deviating during movement, thereby improving the stability of the movement of the second movable plate.

[0021] 5. When the second transmission roller drives the left double door ring or the right double door ring to move to a predetermined position, the first motor is started, so that the first motor drives the first gear to rotate, thereby causing the first gear to engage with the first rack and move, thereby driving the first movable beam and the first end picker to move above the left double door ring or the right double door ring; then, the first lifting mechanism is started, so that the first lifting mechanism drives the first column and the first movable beam to move downward, thereby causing the first end picker to fit with the left double door ring or the right double door ring, thereby causing the first end picker to adsorb the left double door ring or the right double door ring; Then, start the first lifting mechanism, so that the first lifting mechanism drives the left double door ring or the right double door ring to move upward, thereby disengaging the left double door ring or the right double door ring from the second transmission roller; then, start the first motor, so that the first motor drives the first gear to rotate, thereby causing the first gear to engage with the first rack and move, and then the first end picker drives the left double door ring or the right double door ring to move into the punching machine; then, start the first lifting mechanism, so that the first lifting mechanism drives the left double door ring or the right double door ring to move downward, thereby placing the left double door ring or the right double door ring in the punching machine.

[0022] 6. When the first motor drives the first movable beam to move through the first gear and the first rack, the first movable beam pushes the first synchronous belt to move through the first synchronous wheel; since the first column is connected to the two ends of the first synchronous belt through the two first connecting frames, when the first column does not move, the first synchronous belt as a whole will not move, thereby causing the first synchronous belt and the first movable beam to move relative to each other, and then the first synchronous belt drives the first connecting plate and the first end picker to move through the second connecting frame, so as to increase the travel of the first end picker and improve the user experience of the product.

[0023] 7. By fixing the second rack to the first column, the first column supports the second rack, thereby enabling the second rack to move up and down synchronously with the first column; by fixing the second motor to the first mounting plate, the second gear is mounted on the outside of the second output shaft of the second motor, and the second gear is meshed with the second rack, so that the second motor can drive the second gear to rotate, thereby enabling the second gear to mesh with the second rack and move up and down, thereby driving the first column to move up and down to adjust the height of the first column. By fixing two first cylinders to the first mounting plate, the two first cylinders are located at both ends of the first column, and the output ends of the two ground cylinders are simultaneously connected to the top of the first column, so that the two first cylinders cooperate to drive the first column up and down, thereby enabling the two first cylinders to assist the second motor in driving the first column up and down, thereby reducing the load on the second motor and improving the user experience of the product.

[0024] 8. When the second transmission roller drives the left double door ring or the right double door ring to move to a predetermined position, the third motor is started, so that the third motor drives the third gear to rotate, thereby causing the third gear to engage with the third rack and move, thereby driving the second movable beam and the second end picker to move above the left double door ring or the right double door ring; then, the second lifting mechanism is started, so that the second lifting mechanism drives the second column and the second movable beam to move downward, thereby causing the second end picker to fit with the left double door ring or the right double door ring, and then the second end picker to absorb the left double door ring or the right double door ring; Then, start the second lifting mechanism, so that the second lifting mechanism drives the left double door ring or the right double door ring to move upward, thereby disengaging the left double door ring or the right double door ring from the second transmission roller; then, start the third motor, so that the third motor drives the third gear to rotate, thereby causing the third gear to engage the third rack and move, and then the second end picker drives the left double door ring or the right double door ring to move into the punching machine; then, start the second lifting mechanism, so that the second lifting mechanism drives the left double door ring or the right double door ring to move downward, thereby placing the left double door ring or the right double door ring in the punching machine.

[0025] 9. When the third motor drives the second movable beam to move through the second gear and the second rack, the second movable beam pushes the second synchronous belt to move through the second synchronous wheel; since the second column is connected to the two ends of the second synchronous belt through two third connecting frames, when the second column does not move, the second synchronous belt as a whole will not move, thereby causing the second synchronous belt and the second movable beam to move relative to each other, and then the second synchronous belt drives the second connecting plate and the second end picker to move through the seventh connecting frame, so as to increase the travel of the second end picker and improve the product usage experience.

[0026] 10. By fixing the fourth rack to the second column, the second column supports the fourth rack, thereby enabling the fourth rack to move up and down synchronously with the second column; by fixing the fourth motor to the second mounting plate, the fourth gear is mounted on the outside of the second output shaft of the fourth motor, and the fourth gear is meshed with the fourth rack, so that the fourth motor can drive the fourth gear to rotate, thereby enabling the fourth gear to mesh with the fourth rack and move up and down, thereby driving the second column to move up and down, thereby adjusting the height of the second column. By fixing two second cylinders to the second mounting plate, the two second cylinders are located at both ends of the second column, and the output ends of the two cylinders are simultaneously connected to the top of the second column, so that the two second cylinders cooperate to drive the second column up and down, thereby enabling the two second cylinders to assist the fourth motor in driving the second column up and down, thereby reducing the load on the fourth motor and improving the user experience of the product.
