[0030] A method for using a push-pull machine assembly line automatic loading and unloading device is as follows:

[0031] S1. First, the cylindrical workpieces 33 are placed inside the buffer silo 5 and arranged in sequence. The cylindrical workpieces 33 automatically roll down inside the buffer silo 5. The cylindrical workpiece 33 located at the downwardly inclined end of the buffer silo 5 is closely attached to the side of the second isolation plate 8 close to the first isolation plate 7, and the cylindrical workpiece 33 is located between the first isolation plate 7 and the second isolation plate 8;

The movement of the lifting plate 12 drives the lifting bracket 6 to move downward through the connecting rod 13, and the movement of the lifting bracket 6 drives the first isolation plate 7 and the second isolation plate 8 to move downward. When the end of the second booster rod 27 away from the second limit baffle 29 contacts the inner side of the end of the transfer bracket 16 close to the servo motor 18, the second booster rod 27 is stationary. The second gear teeth 28 at the top of the second booster rod 27 drive the booster gear 34 to rotate, and the rotation of the booster gear 34 drives the first booster rod 23 to move close to the servo motor 18 through the first gear teeth 24, until the first limit baffle 26 is close to the outer side of the limit member 22, and at this time, the second isolation plate 8 moves to the top and is flush with the inner bottom end of the buffer bin 5, and the first isolation plate 7 moves to the bottom and is close to the inner bottom end of the buffer bin 5. The first isolation plate 7 separates the cylindrical workpiece 33 at the downwardly inclined end of the fixed support frame 15 from the rest of the cylindrical workpieces 33, and the cylindrical workpiece 33 between the first isolation plate 7 and the second isolation plate 8 loses the obstruction of the second isolation plate 8 and rolls downward, and rolls to the top of the transfer bracket 16 through the guide inclined plate 11, completing the first step of loading;

[0033] S3, control the servo motor 18 to start loading, the driving end of the servo motor 18 drives the threaded shaft 21 to rotate, thereby pushing the moving block 20 to move away from the servo motor 18, when the loading push plate 25 moves to the end of the cylindrical workpiece 33, the loading push plate 25 pushes the cylindrical workpiece 33 to move close to the processing equipment 3 at the top of the transfer bracket 16, when the end of the cylindrical workpiece 33 close to the processing equipment 3 moves to the supporting roller of the processing equipment 3, the cylindrical workpiece 33 pushes the cylindrical workpiece 33 processed on the supporting roller of the processing equipment 3 to move close to the material receiving inclined frame 4, and the processed cylindrical workpiece 33 is pushed to fall into the material receiving inclined frame 4, when the second booster rod 27 moves to the end close to the second limit baffle 29 and contacts the inner side of the end of the transfer bracket 16 away from the servo motor 18, the second booster rod 27 is blocked and remains stationary, The second gear teeth 28 at the top of the second booster rod 27 drive the booster gear 34 to rotate. The rotation of the booster gear 34 drives the first booster rod 23 to move toward the direction of the processing equipment 3 through the first gear teeth 24. When the second limit baffle 29 is close to the outer side of the limit member 22, the cylindrical workpiece 33 is pushed to the middle position of the support roller in the processing equipment 3 by the loading push plate 25. During the movement of the moving block 20, the moving block 20 drives the push-pull rod 32 to move synchronously. The push-pull rod 32 slides on the inner side of the guide slot 14 and pushes the lifting plate 12 to move upward. When the first isolation plate 7 moves to the top of the cylindrical workpiece 33 inside the buffer bin 5, the cylindrical workpiece 33 loses the obstruction and rolls down to the second isolation plate 8 close to the side of the first isolation plate 7 and is blocked by the second isolation plate 8. Then the servo motor 18 is controlled to start resetting, so as to perform cyclic loading and unloading operations.

[0034] Working principle: During use, firstly, the cylindrical workpiece 33 is placed on the inner side of the buffer bin 5 and arranged in sequence by external force, so that the cylindrical workpiece 33 automatically rolls down on the inner side of the buffer bin 5, and the cylindrical workpiece 33 located at the downwardly inclined end of the buffer bin 5 is tightly attached to the side of the second isolation plate 8 close to the first isolation plate 7, and the cylindrical workpiece 33 is located between the first isolation plate 7 and the second isolation plate 8. When the assembly line processing is started, the servo motor 18 is controlled to start and reset, and the driving end of the servo motor 18 drives the threaded shaft 21 to rotate, and the thread The rotation of the rotating shaft 21 pushes the moving block 20 to slide on the limit slide bar 19 and approach the servo motor 18. The movement of the moving block 20 drives the push-pull rod 32 to move. The end of the push-pull rod 32 close to the guide slot 14 slides inside the guide slot 14. Due to the inclined design of the guide slot 14 and the horizontal movement of the push-pull rod 32, the lifting plate 12 is pushed downward when the push-pull rod 32 slides inside the guide slot 14. The movement of the lifting plate 12 drives the lifting bracket 6 to move downward through the connecting rod 13. The movement of the lifting bracket 6 drives The first isolation plate 7 and the second isolation plate 8 move downward, and when the end of the second booster rod 27 away from the second limit baffle 29 contacts the inner side of the end of the transfer bracket 16 close to the servo motor 18, the second booster rod 27 remains stationary, and the booster gear 34 inside the moving block 20 and the limiter 22 continues to move close to the servo motor 18. At this time, the second gear teeth 28 at the top of the second booster rod 27 drive the booster gear 34 to rotate, and the rotation of the booster gear 34 drives the first booster rod 23 to move close to the servo motor 18 through the first gear teeth 24, until the second booster rod 23 is moved close to the servo motor 18. A limit baffle 26 is pressed against the outer side of the limit member 22, and at this time, the second isolation plate 8 moves to the top end and is flush with the inner bottom end of the buffer silo 5, and the first isolation plate 7 moves to the bottom end and is pressed against the inner bottom end of the buffer silo 5. The first isolation plate 7 separates the cylindrical workpiece 33 at the downwardly inclined end of the fixed support frame 15 from the other cylindrical workpieces 33. At this time, the cylindrical workpiece 33 between the first isolation plate 7 and the second isolation plate 8 loses the obstruction of the second isolation plate 8 and rolls downward, and rolls to the top of the transfer bracket 16 through the guide inclined plate 11;

[0035] Then, the servo motor 18 is controlled to start loading, and the driving end of the servo motor 18 drives the threaded shaft 21 to rotate, thereby pushing the moving block 20 to move away from the servo motor 18. The movement of the moving block 20 drives the limit member 22 to move, and the movement of the limit member 22 drives the first booster rod 23 and the loading push plate 25 to move close to the cylindrical workpiece 33 at the top of the transfer bracket 16. When the loading push plate 25 is tightly attached to the end of the cylindrical workpiece 33, the loading push plate 25 pushes the cylindrical workpiece 33 to move close to the processing equipment 3 at the top of the transfer bracket 16. When the cylindrical workpiece 33 is close to one end of the processing equipment 3 When the cylindrical workpiece 33 moves to the support roller of the processing equipment 3, the cylindrical workpiece 33 is pushed by the loading push plate 25 to continue to move onto the processing equipment 3. The movement of the cylindrical workpiece 33 pushes the cylindrical workpiece 33 processed on the support roller of the processing equipment 3 to move close to the receiving inclined frame 4. When the processed cylindrical workpiece 33 moves to the point where the center of gravity is separated from the support roller of the processing equipment 3, the cylindrical workpiece 33 falls into the receiving inclined frame 4. When the second booster rod 27 moves to the end close to the second limit baffle 29 and contacts the inner side of the end of the transfer bracket 16 away from the servo motor 18, the second booster rod 27 is The block remains stationary, and the booster gear 34 inside the moving block 20 and the limit member 22 continues to move away from the servo motor 18. At this time, the second gear teeth 28 at the top of the second booster rod 27 drive the booster gear 34 to rotate. The rotation of the booster gear 34 drives the first booster rod 23 to move toward the direction of the processing equipment 3 through the first gear teeth 24. The movement of the first booster rod 23 drives the loading push plate 25 to move relative to the limit member 22 toward the direction of the processing equipment 3 at the top of the limit member 22 until the second limit baffle 29 is close to the outer side of the limit member 22. At this time, the cylindrical workpiece 33 is pushed by the loading push plate 25. The plate 25 is pushed to the middle position of the support roller in the processing equipment 3. During the movement of the moving block 20, the moving block 20 drives the push-pull rod 32 to move synchronously. The end of the push-pull rod 32 close to the guide groove 14 slides on the inner side of the guide groove 14 and pushes the lifting plate 12 to move upward. When the first isolation plate 7 moves to the top of the cylindrical workpiece 33 inside the buffer silo 5, the cylindrical workpiece 33 loses the obstruction and rolls down to the second isolation plate 8 close to the side of the first isolation plate 7 and is blocked by the second isolation plate 8. Then the servo motor 18 is controlled to start resetting, so as to perform cyclic loading and unloading operations.
