The transfer mechanism is used to transfer the transport cart 30 between the first rail 10 and the second rail 20, thereby transferring the workpiece to be processed to a different downstream process. The transfer mechanism comprises a movable trolley 40 for carrying the conveying trolley 30, the movable trolley 40 is provided with a carrying rail which is in butt joint with the first rail 10 or the second rail 20, and the movable trolley 40 can be a transportation device with or without autonomous power. It is also possible to provide a fixed track on the ground, by which the mobile trolley 40 moves from the vicinity of the first track 10 to the vicinity of the second track 20.

In one embodiment of the present invention, the transport vehicle 30 has autonomous power and can travel on the first track 10 and the second track by itself without the aid of other external driving mechanisms. The related structure of the conveying trolley 30 can adopt the prior art, and the description is omitted.

The transfer mechanism includes a mobile trolley 40 having autonomous power, and a carrying rail that is butted against the first rail 10 or the second rail 20 is provided on the mobile trolley 40. The mobile trolley 40 is used for transferring the transport trolley 30, and the structure thereof can also adopt the prior art, and the description is omitted.

When the transport vehicle 30 travels on the first track 10, the movable trolley 40 is located at one end of the first track 10, and the bearing track is connected with the first track 10. If the downstream processes of the workpieces to be processed have multiple choices, the conveying trolley 30 drives into the bearing track of the movable trolley 40 and stops moving, the movable trolley 40 drives to one end of the corresponding second track 20 according to the process design, so that the bearing track is connected with the second track 20, the conveying trolley 30 automatically drives out of the bearing track to enter the second track 20, and the workpieces to be processed are conveyed to the corresponding processes for processing.

In one embodiment of the present invention, the first track 10 and the second track 20 are disposed parallel to each other, and the mobile cart 40 has no autonomous power and requires an external driving mechanism to provide power to move between the first track 10 and the second track 20. The bottom of the movable trolley 40 is provided with a roller, a fixed track is arranged on the moving route of the movable trolley 40, and the movable trolley 40 moves along the fixed track to ensure that the bearing track on the movable trolley can be accurately butted with the first track 10 and the second track 20.

In this embodiment, the second driving mechanism drives the movable carriage 40 to transfer and dock the first rail 10 or the second rail 20. The second driving mechanism includes a second driving motor, a second sprocket 51, and a second chain 52. The second chain wheels 51 are disposed at both ends of the moving path of the moving cart 40, the second chain 52 is engaged with the second chain wheels 51, and the second driving motor drives the second chain 52 to move by driving the second chain wheels 51. The second chain 52 is connected with the movable trolley 40 in a transmission manner, which may be implemented by the prior art, for example, a sprocket matched with the second chain 52 is sleeved on a wheel shaft of the movable trolley 40, the sprocket is engaged with the second chain 52, and when the second chain 52 moves, the wheel of the movable trolley 40 is driven by the sprocket to rotate, so as to drive the movable trolley 40.

In one embodiment of the present invention, the transport vehicle 30 does not have autonomous power, but is driven by an external drive mechanism to travel on the first track 10 and the second track 20. At this moment, the structure of the conveying trolley 30 is simpler, the conveying trolley is not easy to damage, and the manufacturing cost is lower.

In the present embodiment, the transport vehicle 30 is driven to travel on the first rail 10 or the second rail 20 by the first driving mechanism provided near the first rail 10 and the second rail 20.

Preferably, the first driving mechanism includes a first driving motor, a first sprocket 61, and a first chain 62. The first chain wheel 61 is respectively arranged at two ends of the first track 10 and the second track 20, the first chain 62 is engaged with the first chain wheel 61, the extending direction of the first chain 62 is the same as that of the first track 10 or the second track 20, and the first driving motor drives the first chain 62 to move circularly by driving the first chain wheel 61. The first chain 62 is in transmission connection with the transport trolley 30, and when the first chain 62 moves, the transport trolley 30 is driven to travel along the first track 10 or the second track 20.

The first driving motor can be a servo motor, a stepping motor, a hydraulic motor and other power output elements. The output shaft of the first driving motor may be connected to the first sprocket 61 through a gear train, thereby driving the first sprocket 61 to rotate.

The transmission connection mode of the first chain 62 and the conveying trolley 30 can adopt the prior art, for example, a chain wheel matched with the first chain 62 is sleeved on a wheel shaft of the conveying trolley 30, the chain wheel is meshed with the first chain 62, and when the first chain 62 moves, the wheel of the conveying trolley 30 is driven by the chain wheel to rotate, so that the conveying trolley 30 is driven.

In this embodiment, since the transport vehicle 30 needs to be driven by the first driving mechanism, and the length of the first chain 62 is equivalent to that of the first track 10 or the second track 20, the transport vehicle 30 needs to be smoothly transited by an external force when entering or exiting the carrying track of the movable trolley 40.

Specifically, the transfer mechanism further includes a loading and unloading mechanism for assisting the conveying trolley 30 to move into or out of the carrying track of the movable trolley 40.

The getting-on/off mechanism includes a paddle 70 provided near the movable carriage 40, and the paddle 70 is rotatable. When the transport trolley 30 travels to the end of the first track 10, the first paddle 70 contacts the transport trolley 30 by rotating, and continues to rotate to push the transport trolley 30 into the bearing track on the mobile trolley 40. When the mobile trolley 40 transfers the transport trolley 30 to the vicinity of the second rail 20, the other dial 70 pushes the transport trolley 30 into the second rail 20 from the carrying rail on the mobile trolley 40 by rotating.

Further, the conveying trolley 30 is further provided with a stopper 80, and when the shifting block 70 rotates, the conveying trolley 30 is assisted to move into or out of the bearing track of the movable trolley 40 by pushing the stopper 80.

In order to realize the rotation of the shifting block 70 in the above-mentioned getting-on and getting-off mechanism, an additional power source may be required. To further simplify the related structure, the shift block 70 may be fixed to the first sprocket 61 near the movable trolley 40, and when the first sprocket 61 rotates, the shift block 70 can rotate with the first sprocket 61, and the rotation direction is also the same as that of the first sprocket 61. When the transport trolley 30 travels to the end of the first track 10, the rotating paddle 70 contacts the stop 80 on the transport trolley 30 and pushes it forward, causing the transport trolley 30 to ride into the bearing track on the mobile trolley 40. Likewise, the paddle 70 adjacent to the second track 20 rotates continuously, and the paddle 70 drives the transfer car 30 out of the load bearing track on the mobile trolley 40 by pushing the stopper 80 when the transfer car 30 is transferred to the vicinity of the second track 20.
