Description

Technical Field

[0001] This utility model relates to the field of conveying system technology, and in particular to an anti-collision mechanism for an automatic line servo trolley system. Background Technology

[0002] Some large workpieces need to be transported to another parallel automated production line after being processed on one automated production line to complete the next process. Therefore, a trolley conveyor system is required at both ends of the two automated production lines.

[0003] The applicant's earlier application for an automatic line servo trolley system (authorization announcement number CN120191680B) solved the problem of trolleys frequently getting stuck and colliding during the movement and transportation process when docking with the automatic production line. However, the structure of its longitudinal drive mechanism is relatively complex. Due to the presence of the side supports and longitudinal guide rails, its overall width is relatively wide, which is not conducive to the installation of other mechanisms. At the same time, the manufacturing and assembly costs are also relatively high. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-collision mechanism for an automatic line servo trolley system that is simple in structure, stable in conveying, highly safe, and low in manufacturing cost.

[0005] This utility model is achieved through the following technical solution: A collision avoidance mechanism for an automated line servo trolley system includes a base, a trolley mounted on the base, and a collision avoidance drive assembly capable of driving the trolley to move along the base. The anti-collision drive assembly includes a servo motor, a trolley, a buffer seat, and a central slide rail. A set of guide rails is provided at the top of the base. The trolley is slidably connected to the guide rails and is correspondingly positioned below the trolley. The servo motor is fixed to one side of the base and connected to the trolley. The central slide rail is fixed to the middle of the inner side of the base and is correspondingly positioned below the trolley. The central slide rail is parallel to the guide rails. The buffer seat is slidably connected to the central slide rail. A stop block is fixed to one side of the buffer seat. The stop block is elastically connected to the rear side of the base through an elastic component. The stop block can abut against the edge of the trolley. The servo motor can drive the trolley to move along the guide rails. The trolley can push the trolley to move along the central slide rails. The buffer seat and the stop block can buffer the movement of the trolley.

[0006] Since the base may vibrate during movement, in order to prevent the trolley from moving along the base during transfer, the top of the buffer seat is provided with a backstop component to prevent the trolley from moving backward. The backstop component includes a fixed block, a flipping block, a roller and a first spring. The fixed block is fixed to the top of the buffer seat. One end of the flipping block is rotatably connected to the fixed block, and the bottom of the other end is elastically connected to the fixed block through the first spring. The roller is rotatably connected to the top of the flipping block, and the roller can abut against the edge of the trolley.

[0007] To avoid impacts caused by the movement of the trolley, the elastic component preferably includes a guide rod, a second spring, and a fixing rod. The guide rod is fixed to the rear side of the base and parallel to the central slide rail. One end of the fixing rod is fixed to the stop block, and the other end of the fixing rod is elastically connected to the guide rod through the second spring.

[0008] To facilitate the movement of the trolley along the guide rail, the servo motor is connected to the trolley via a sprocket assembly.

[0009] The beneficial effects of this utility model are: the anti-collision mechanism of the automatic line servo trolley system simplifies the original longitudinal drive mechanism, greatly reducing production and manufacturing costs. Through the cooperation of servo motor, trolley, buffer seat and center slide rail, the trolley can achieve precise docking and transfer with the automatic production line, and ensure stability during transportation. At the same time, through the special design of the anti-backward component and the buffer seat, the trolley can be prevented from moving or shaking during transportation and from colliding with other trolleys, thus ensuring safety.

The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0012] like Figure 1The anti-collision mechanism of an automatic line servo trolley system shown includes a base 3, a trolley 2 disposed on the base 3, and an anti-collision drive assembly capable of driving the trolley 2 to move along the base 3. The base 3 has rails 1 on both sides that are connected to the production line, and the trolley 2 is transported by the production line to the rails 1 on the base 3.

[0013] Specifically, in combination Figure 2 As shown, the anti-collision drive assembly includes a servo motor 4, a trolley 5, a buffer seat 9, and a central slide rail 8. A set of guide rails 7 is provided at the top of the base 3, parallel to the track 1. The bottom of the trolley 5 is slidably connected to the guide rails 7 via several pulleys and is correspondingly positioned below the trolley 2. The trolley 5 can push the trolley 2 to move. The servo motor 4 is fixed to one side of the base 3 and connected to the trolley 5 via a sprocket assembly 18. The central slide rail 8 is fixed to the middle of the inner side of the base 3 and correspondingly positioned below the trolley 5. The central slide rail 8 is connected to the guide rails 7. Parallel, the bottom end of the buffer seat 9 is slidably connected to the central slide rail 8 via a slider, and a stop block 10 is fixed on one side of the buffer seat 9. The stop block 10 is elastically connected to the rear side of the base via an elastic component. The elastic component includes a guide rod 13, a second spring 12, and a fixing rod 11. The guide rod 13 is fixed to the rear side of the base 3 and is parallel to the central slide rail 8. One end of the fixing rod 11 is fixed to the stop block 10, and the other end of the fixing rod 11 is connected to the guide rod 13 via the second spring 12 to achieve an elastic connection. The stop block 10 can abut against the edge of the trolley 5. In addition, the top of the buffer seat 9 is also provided with a backstop component to prevent the trolley 2 from retracting. The backstop component includes a fixed block 14, a flipping block 15, a roller 16 and a first spring 17. The fixed block 14 is fixed to the top of the buffer seat 9. One end of the flipping block 15 is rotatably connected to the fixed block 14, and the bottom of the other end is elastically connected to the fixed block 14 through the first spring 17. The roller 16 is rotatably connected to the top of the flipping block 15, and the roller 16 can abut against the edge of the trolley 2.

[0014] After the trolley 2 is transported from the production line to the track 1 of the base 3, the servo motor 4 drives the pusher 5 to move backward along the guide rail 7 through the sprocket assembly 18. The pusher 5 pushes the trolley 2 backward. When the edge of the trolley 2 touches the roller 16, the roller 16 is subjected to a certain force. Due to the elasticity of the first spring 17, the tilting block 15 deflects downward, and the trolley 2 passes the stop assembly and continues to move backward. Finally, the edge of the pusher 5 contacts the stop block 10. The elastic force of the second spring 12 buffers the pusher 5. At this time, the servo motor 4 continues to operate, and the pusher 5 pushes the stop block 10 to move backward a certain distance. The second spring 12 contracts, and the trolley 2 moves backward a small distance at the same time. The trolley 2 can then completely detach from the current production line. At the same time, since the stop assembly is located inside the trolley 2, the trolley 2 is blocked, so the trolley 2 will not shake. This achieves the lateral transfer of the trolley 2, ensuring the stability of the trolley 2 during transport and preventing the trolley 2 from colliding with the trolley on another line when it is transferred to another line.
