When the trolley is pushed along the linear guide rail by the buffer frame, the push plate can push the locking plate to deflect upward through the connecting plate and the connecting rod, so that the hook portion of the locking plate is locked to the locking shaft at the bottom end of the trolley.
[0010] In order to ensure the stability of the base during operation, the bottom end of the base is provided with two groups of first rollers that can slide along the top surface of the transverse slide rail and at least one group of second rollers that can slide along the side surface of the transverse slide rail.

The bottom end of the support 11 is slidably connected along the linear guide 12 through a slider. The buffer frame 13 is fixed to the rear end of the support 11. A stopper 17 is fixed to the front end of the buffer frame 13. The rear end of the buffer frame 13 is elastically connected to the top of the rear side of the base 7 through an elastic component. The elastic component includes a group of bolts 14 and a group of springs 15. The bolts 14 are parallel to the linear guide rails 12 and fixed to the base 7. A group of guide rods 16 are fixed to the buffer frame 13. The guide rods 16 are arranged opposite to the bolts 14. One end of the spring 15 is fixed to the bolts 14 and the other end is fixed to the guide rods 16. When the buffer frame 13 is subjected to force, the guide rods 16 compress the springs 15. The longitudinal slide rails 25 are a group fixed to the top of the base 7. The longitudinal slide rails 25 are parallel to the linear guide rails 12. The trolley 24 slides along the longitudinal slide rails. 25 sliding connection, and the trolley 24 is correspondingly arranged under the buffer frame 13, a push block 20 is fixed at one end of the trolley 24, and a group of fourth rollers 26 sliding along the top end surface of the longitudinal slide rail 25 and a group of fifth rollers 27 sliding along the bottom end surface of the longitudinal slide rail 25 are provided at the bottom end of the trolley 24. The longitudinal servo motor 22 is fixed to one side of the base 7, and the longitudinal servo motor 22 is connected to the trolley 24 through the sprocket assembly 23. The longitudinal servo motor 22 can drive the trolley 24 to move along the longitudinal slide rail 25 through the sprocket assembly 23, and the fourth roller 26 and the fifth roller are used to move the trolley 24 along the longitudinal slide rail 25. 27 cooperates to ensure the stability of the trolley 24 during movement. The longitudinal guide rail 18 is a group and is fixed to the top of the support 11. The longitudinal guide rail 18 can be docked with the guide rail of the production line. The bottom of the trolley 19 is provided with a group of sixth rollers 21 that can slide along the longitudinal guide rail 18. The trolley 19 is located in front of the trolley 24. The trolley 24 can push the stopper 17 of the buffer rack 13 through the push block 20 to move the support 11 along the linear guide rail 12. At the same time, the trolley 24 can push the trolley 19 through the push block 20 to move the trolley 19 along the longitudinal guide rail 18.
[0024] In addition, the servo push trolley device also includes an automatic locking mechanism that can automatically lock or unlock the trolley 19. Specifically, the automatic locking mechanism includes a support plate 28, a locking plate 29, a push plate 30, a connecting plate 31 and a connecting rod 32. The support plate 28 is fixed in the base 7 and is correspondingly arranged under the trolley 19. The bottom end of the locking plate 29 is rotatably connected to the center position of the top surface of the support plate 28. The top end of the locking plate 29 has a hook portion. The push plate 30 is fixed to the front end of the support 11, and the push plate 30 is correspondingly arranged on the front side of the locking plate 29. The push plate 30 is higher than the support plate 28. The connecting plate 31 is fixed at the center position of the bottom end of the push plate 30. One end of the connecting rod 32 is rotatably connected to the connecting plate 31, and the other end is rotatably connected to the locking plate The bottom end of 29 is rotatably connected. When the trolley 24 pushes the buffer frame 13 to make the support 11 move backward along the linear guide rail 12, the push plate 30 fixed to the support 11 can push the locking plate 29 to deflect upward through the connecting plate 31 and the connecting rod 32, so that the hook portion of the locking plate locks the locking shaft 33 at the bottom end of the trolley 19. At this time, the trolley 19 will no longer move along the longitudinal guide rail 18 to achieve locking. When the trolley 24 pushes the trolley 19 forward, the buffer frame 13 is no longer subjected to force, and the support 11 moves forward along the linear guide rail 12. The push plate 30 fixed to the support 11 pulls the locking plate 29 to deflect downward through the connecting plate 31 and the connecting rod 32, and the locking shaft 33 is no longer blocked by the locking plate 29 and can move forward along the longitudinal guide rail 18 to achieve unlocking.
[0025] During processing, the workpiece processed on the upper production line is carried by the trolley 19, and multiple trolleys 19 are pressed against each other, and the trolley 19 is pushed to the longitudinal guide rail 18 of the automatic line servo trolley system of the present invention through the production line. At this time, the longitudinal guide rail 18 is seamlessly connected with the guide rail of the production line, and the trolley 19 moves backward along the longitudinal guide rail 18 through the sixth roller 21. When the trolley 19 is completely out of the track of the production line, the longitudinal servo motor 22 drives the trolley 24 to move backward along the longitudinal slide rail 25 through the sprocket assembly 23. The buffer frame 13 is subjected to force and gradually compresses the spring 15 through the guide rod 16. At the same time, the buffer frame 13 drives the support 11 to move backward along the linear guide rail 12, so that the longitudinal guide rail 18 on the support 11 is out of the guide rail of the production line, and the push plate 30 pushes the locking plate 29 to deflect upward through the connecting plate 31 and the connecting rod 32, so that the hook part of the locking plate is locked to the locking shaft 33 at the bottom end of the trolley 19, and the trolley 19 is locked, completing the trolley 19 and the workpiece Then, the horizontal servo motor 4 drives the base 7 to move horizontally along the horizontal slide rail 2 as a whole through the gear 5 and the rack 3, so that it moves to the import end of another production line. After it is in place, the longitudinal servo motor 22 drives the trolley 24 to move forward along the longitudinal slide rail 25 through the sprocket assembly 23. The trolley 24 applies thrust to the trolley 19 through the push block 20, and with the restoring force of the spring 15, the support 11 first moves forward along the linear guide rail 12, and the longitudinal guide rail 18 on the support 11 is docked with the guide rail of the production line. The push plate 30 pulls the locking plate 29 downward through the connecting plate 31 and the connecting rod 32, and the locking shaft 33 is no longer blocked by the locking plate 29, and the trolley 19 can move forward along the longitudinal guide rail 18. Finally, the trolley 24 pushes the trolley 19 to enter the track on the corresponding production line and enter the subsequent process. By arranging the automatic line servo trolley system at both ends of the two production lines, the rotary transportation of the workpiece between the two production lines can be realized.
