After the locking is completed, the cross arm 63 rises and the above steps are repeated again.

[0042] Reference Figures 1 to 10The first transfer rail 21 and the second transfer rail 22 are respectively provided with screw rods 23 arranged horizontally in the front-to-back direction, and each screw rod 23 is screwed with a transfer slider 24 for transferring the material tray 100 to the opposite conveying rail, and the top of the transfer slider 24 is provided with a docking rail 25 for docking with the first conveying rail 11 or the second conveying rail 12, and the transfer slider 24 on the first transfer rail 21 can move forward and backward, so that the docking rail 25 set on the top of the transfer slider 24 located on the first transfer rail 21 is docked with the first conveying rail 11 or the second conveying rail 12, and the transfer slider 24 on the second transfer rail 22 can move forward and backward, so that the docking rail 25 on the top of the transfer slider 24 located on the second transfer rail 22 is docked with the first conveying rail 11 or the second conveying rail 12.

[0043] Reference Figures 1 to 10 In this embodiment, the number of the material trays 100 is at least two, and grooves 1002 are concavely provided on both sides of each material tray 100; the first conveying track 11 and the second conveying track 12 are provided with a movable plate 14 extending in the left-right direction and capable of translation, and the movable plate 14 is provided with a guide shaft 15 extending in the left-right direction and capable of rotation and a cylinder 16 for driving the guide shaft 15 to rotate on the side away from the conveying track; in this embodiment, the side opposite to the conveying track is provided with a slide rail 13, and the side of the movable plate 14 facing the conveying track is provided with a slider 141, by setting other power sources such as motors and pneumatic cylinders, the movable plate 14 can be movably arranged on the conveying track; the above-mentioned guide shaft 15 is used to move the material tray 100 transferred from the first transfer track 21 or the second transfer track 22 to the first conveying track 11 or the second conveying track 12, and the guide shaft 15 is provided with at least three protrusions 151 that can be inserted into the above-mentioned grooves 1002, one of the protrusions 151 is located above the first transfer track 21, another protrusion 151 is located above the second transfer track 22, and another protrusion 151 is located at the screw conveying mechanism.

[0044] The above-mentioned cylinder 16 is erected on the movable plate 14 and is located below the guide shaft 15. The output shaft of the cylinder 16 is hinged with a connecting piece 17, and the other end of the connecting piece 17 is connected to the guide shaft 15. In this embodiment, the connecting piece 17 and the output shaft of the cylinder 16 are not rigidly connected.

[0045] Reference Figures 1 to 10When performing the locking process, the worker first puts the workpieces into the placement grooves 1001 of the two material trays 100 in sequence, and then the two material trays 100 start to move from the first conveying track 11. The first material tray 100 with the workpiece does not stop when passing the first screw aligning machine 51. When the first material tray 100 moves to the end of the first conveying track 11 close to the first transfer track 21, the movable plate 14 on the first conveying track 11 moves to the left, thereby driving the guide shaft 15 to move. When the protrusion 151 on the guide shaft 15 corresponds to the groove 1002 of the material tray 100, the movable plate 14 stops moving, and then the cylinder 16 is lifted, thereby driving the guide shaft 15 to rotate, and then the protrusion 151 set on the guide shaft 15 is stuck in the groove 1002 of the material tray 100, and then the movable plate 14 on the first conveying track 11 moves to the right, thereby moving the material tray 100 It moves to the docking track 25 of the transfer slider 24 on the first transfer track 21, then the cylinder 16 retracts, and then the protrusion 151 set on the guide shaft 15 disengages from the groove 1002 of the material tray 100, and further driven by the screw rod 23, the transfer slider 24 on the first transfer track 21 moves to one end of the second conveying track 12, at this time, the cylinder 16 located on the second conveying track 12 is lifted, thereby driving the guide shaft 15 of the second conveying track 12 to rotate, so that the protrusion 151 on the guide shaft 15 is stuck in the groove 1002 of the material tray 100 on the second transfer track 22, and then the movable plate 14 of the second conveying track 12 moves to the left, thereby bringing the material tray 100 into the second conveying track 12, and further the cylinder 16 retracts, the protrusion 151 of the guide shaft 15 disengages from the groove 1002 of the material tray 100, and the material tray 100 moves on the second conveying track 12.

[0046] Reference Figures 1 to 10 When the tray 100 moves to the position of the second screw aligning machine 52, the cylinder 16 arranged on the second conveying track 12 is lifted again so that the guide shaft 15 is located at the protrusion 151 of the second screw aligning machine 52 and is inserted into the groove 1002 of the tray 100. This is to keep the tray 100 in a stable state when screwing and ensure the accuracy of screw locking. Further, the Y-axis beam 62 drives the cross arm 63 to enable the adsorption component and the locking component to start assembling the screws of the workpiece on the tray 100. At the same time, the other tray 100 moves to the position of the first screw aligning machine 51 and starts to assemble the screws.

[0047] Reference Figures 1 to 10, when the workpiece placed on the tray 100 located on the second conveying track 12 is locked, the cylinder 16 arranged on the second conveying track 12 retracts to make the protrusion 151 of the guide shaft 15 located at the position of the second screw aligning machine 52 disengage from the groove 1002 of the tray 100, and the tray 100 moves toward the second transfer track 22. When the tray 100 passes the industrial camera 30 located above the second conveying track 12, it will stay for a period of time. The industrial camera 30 takes a picture of the locked workpiece on the tray 100 and transmits the signal to the PLC control system (not shown in the figure). Because the PLC control system is an existing well-known technology, it will not be described in detail here. The PLC control system determines whether the screw height of the workpiece after locking is qualified, and then moves to the position of the material picking robot 40 and stays for a period of time. Further, the material picking robot 40 clamps the workpiece with qualified locking to the qualified conveying line 200 or clamps the workpiece with unqualified locking to the unqualified conveying line 300.

[0048] Then the protrusion 151 of the guide shaft 15 on the second conveying track 12 is again inserted into the groove 1002 of the material tray 100, and then the movable plate 14 of the second conveying track 12 moves to the left, bringing the material tray 100 to the transfer track 25 of the transfer slider 24 on the second transfer track 22, and further the transfer slider 24 on the second transfer track 22 is moved to the other end by the screw rod 23, and then the worker loads the empty material tray 100. At this time, the workpiece on the material tray 100 located on the first conveying track 11 after locking is completed is transferred to the second conveying track 12 through the first transfer track 21, and then moved to the bottom of the industrial camera 30 for taking pictures, and then moved to the position of the material picking robot 40 to stay for unloading. After unloading is completed, it moves to the first conveying track 11 through the second transfer track 22, and the worker loads the empty material tray 100. Because its transfer steps are consistent with the above description, they are not repeated. This is the processing flow of the automatic locking station.

[0049] The utility model conveys the workpiece to be locked by a conveying track, and a screw conveying mechanism for arranging screws, an adsorption component for sucking up the screws and a locking component for locking the screws are arranged outside one side of the conveying track, thereby realizing automatic locking of the steering wheel control panel of the automobile.
