[0031] Embodiment 1

[0032] Referring to Figures 1 - 6 As shown, a bending stop mechanism of the present utility model includes:

[0033] A frame 1, the end of the frame 1 is rotatably connected to a main shaft 2, the main shaft 2 is fixedly sleeved with a disc 4, and the disc 4 is movably connected to a telescopic pin 13;

[0034] A support body 6, which is arranged along the length direction of the frame 1;

[0035] A conveyor chain, which is rotatably connected to the frame 1 and the axis where it is located is parallel to the support body 6;

[0036] A tray 16, which is provided with a roller 17 movably connected to the support body 6, an insertion hole 19 adapted to the telescopic pin 13, and a driven gear 18 meshing with the conveyor chain;

[0037] A locking component for locking or unlocking the slave gear 18.

[0038] In a bending stop mechanism of the present utility model, during the translational transportation of the tray 16, the conveyor chain rotates, and the locking component locks the slave gear 18. The conveyor chain drives the tray 16 to move along the support body 6 through meshing with the slave gear 18. When the tray 16 needs to stop during bending, the telescopic pin 13 on the disc 4 extends and inserts into the jack 19 of the tray 16, clamping the tray 16 and the disc 4, so that the locking component releases the locking of the tray 16, and the tray 16 and the disc 4 are locked. The disc 4 drives the connected tray 16 to rotate together to realize the bending of the tray 16 on the frame 1. When the bending of the tray 16 is completed, the jack 19 on the tray 16 and the telescopic pin 13 are disengaged, releasing the connection between the tray 16 and the disc 4, and the conveyor chain continues to drive the tray 16 to move forward to complete the bending stop.

[0039] Refer to Figure 1 As shown, the main shaft 2 is driven to rotate by a first motor, and the conveyor chain is driven to rotate by a second motor. During the translational transportation of the tray 16, the second motor drives the conveyor chain to rotate; when the tray 16 reaches the position where it needs to stop during bending, the first motor starts and drives the main shaft 2 to rotate, so that the main shaft 2 and the disc 4 rotate independently, and the conveyor chain rotates independently in a cycle.

[0040] The circumferential surface of the disc 4 is provided with a telescopic hole 14, the telescopic hole 14 contains a first elastic member 15, the telescopic pin 13 is connected to the end of the first elastic member 15 and is movably connected in the telescopic hole 14. When the tray 16 reaches the flipping station at the end of the frame 1, the first elastic member 15 drives the telescopic pin 13 to snap into the jack 19 of the tray 16, locking the disc 4 and the tray 16. The disc 4 and the main shaft 2 do not rotate, so the tray 16 remains relatively stationary on the frame 1.

[0041] Refer to Figures 1 - 2 As shown, a main gear 3 is rotatably sleeved on the main shaft 2, the conveyor chain is meshed and driven by the main gear 3, and the main gear 3 is rotatably connected to the main gear 3 in a relatively movable manner, so that the rotation of the disc 4 and the conveyor chain is independent of each other. When the main shaft 2 is driven by power to rotate, the main gear 3 sleeved on the main shaft 2 does not rotate accordingly. The main gear 3 supports the conveyor chain at the end of the frame 1 and does not drive the main shaft 2 to rotate when it rotates.

[0042] Refer to Figures 5 - 6As shown, the locking assembly includes: a sleeve 20 disposed on the tray 16, a second elastic member 21 received in the sleeve 20, and a friction pin 22 connected to the end of the second elastic member 21. The end of the friction pin 22 abuts against the driven gear 18. The static friction between the friction pin 22 and the driven gear 18 is greater than the movement resistance of the tray 16. When locking the tray 16, due to the elastic force of the second elastic member 21, the friction pin 22 always maintains close contact with the driven gear 18. At this time, the static friction between the friction pin 22 and the driven gear 18 is greater than the movement resistance of the tray 16, and the driven gear 18 cannot rotate. The driven gear 18 is driven by the conveyor chain to translate. When it moves to the bending position, the telescopic pin 13 is inserted into the tray 16 to perform plug-in locking on the tray 16, unlocking the locking assembly. The friction pin 22 slides relative to the driven gear 18, thereby locking the position of the tray 16 and the disc 4. The driven gear 18 is rotationally connected to the tray 16 and the conveyor chain.

[0043] Referring to Figures 3 - 4 As shown, a turntable 12 is also fixedly sleeved on the main shaft 2. The turntable 12 is respectively provided with a first stop piece 8 and a second stop piece 9. The first stop piece 8 and the second stop piece 9 have an included angle. The frame 1 is respectively provided with a first sensor 10 and a second sensor 11 corresponding to the first stop piece 8 and the second stop piece 9. When the main shaft 2 rotates, it drives the turntable 12 to rotate together. When the first stop piece 8 on the turntable 12 rotates to a position corresponding to the first sensor 10, the first sensor 10 will detect a signal and transmit it to the control system. As the turntable 12 continues to rotate, when the second stop piece 9 rotates to a position corresponding to the second sensor 11, the second sensor 11 will detect a signal and transmit it to the control system. To start or stop the first motor, judge and control the rotation direction and angle of the turntable 12, and then realize the monitoring and control of the operating state of the equipment.

[0044] The frame 1 is provided with a guiding member 5 on one side of the main shaft 2. When the tray 16 approaches the guiding member 5, the guiding member 5 guides the movement of the tray 16. The tray 16 advances under the restriction of the guiding member 5 and approaches the position of the telescopic pin 13. When the tray 16 reaches a position corresponding to the telescopic pin 13, the telescopic pin 13 is inserted into the jack 19 of the tray 16 to complete the locking of the tray 16 and the telescopic pin 13.

[0045] A position sensor is provided on one side of the guiding member 5. When the tray 16 is driven by the conveyor chain and moves along the support 6 and is guided by the guiding member 5 to the position of the telescopic pin 13, once the tray 16 reaches the accurate position for locking with the telescopic pin 13, the position sensor will be triggered. The sensor sends the detected in-place signal of the tray 16 to the control system. After receiving the signal, the control system starts the first motor to perform bending.

[0046] Referring to Figure 1As shown, a spacing space 7 is formed along the movement path of the tray 16 on the support body 6, and the roller 17 is limited within the spacing space 7 to limit the tray 16 and prevent the tray 16 from detaching from the frame body 1.

[0047] Embodiment 2

[0048] This embodiment discloses a conveying line, including a bending stop mechanism as described in Embodiment 1.

[0049] For the conveying line described in this embodiment, at the starting end of the conveying line, a feeding system is provided. The feeding system is composed of an automated robotic arm or a conveyor belt. The tray 16 is equipped with a dedicated fixing device to ensure that the material does not shift or fall during transportation. Corresponding sensors and monitoring devices are provided on the conveying line. Through the sensors and monitoring devices, the operating state of the conveying line can be monitored in real time, including parameters such as the position, speed, and bending angle of the tray 16, and this data is fed back to the control system. The control system analyzes, processes, and adjusts the data. When the tray 16 reaches the unloading position, the unloading system starts to work. The unloading system can adopt pneumatic, electric, or mechanical means to unload the material from the tray 16 and convey it to the next production process or storage area. Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
