[0037] An industrial robot 43 is connected to the crane body 4 and includes a multi-rotating mechanical arm 431 and a clamping mechanism connected to the end of the mechanical arm 431. The clamping mechanism includes a first clamp 432 and a second clamp 433 for clamping a workpiece 6. The first clamp 432 and the second clamp 433 are respectively used to clamp a single workpiece 6.

[0039] The control method of the above workpiece loading and unloading connection device is as follows:

[0040] Step 1: Control the first transfer mechanism 14 to transfer the tray body 2 from the first docking station 11 to the second docking station 12;

[0041] Step 2: Control the traveling body 4 to move along the traveling track 3 to one of the tray parking stations 42 located at the position of the second docking station 12;

[0042] Step 3: Control the transfer of the tray body 2 parked at the second docking station 12 to the tray parking station 42 of the accompanying platform 41;

Since there are more than two tray parking stations 42 on the traveling body 4, when one of the trays is full of processed workpieces 6, the workpiece 6 can be loaded and unloaded at the next tray parking station 42. When all CNC machine tools 5 are in a non-idle state, the traveling body 4 is controlled to move to the second docking station 12 to circulate the tray body 2 full of processed workpieces 6. This greatly saves the time for automatic circulation of the workpiece 6 and improves production efficiency.

[0047] As a preferred embodiment, the crane body 4 is further provided with a blowing mechanism for blowing away debris on the surface of the CNC machine tool fixture;

[0048] In step 4, "controlling the industrial robot 43 to transfer the processed workpiece 6 clamped by the second fixture 433 to the position of the unprocessed workpiece 6 originally taken away" is specifically: controlling the industrial robot 43 to transfer the processed workpiece 6 clamped by the second fixture 433 to the position of the purge mechanism, controlling the purge mechanism to purge the debris on the surface of the CNC machine tool fixture, and then controlling the workpiece 6 to be transferred to the position of the unprocessed workpiece 6 originally taken away.

[0051] The step 3 is specifically as follows: the two lifting support platforms 121 of the second docking station 12 are supported on the ear plates of the tray body 2, and the limit block is limited in cooperation with the first limit hole 22, and the lifting drive component 122 is controlled to drive the lifting support platform 121 to rise until the bottom height of the carried tray body 2 is higher than the upper height of the accompanying platform, and the traveling body 4 is controlled to drive the accompanying platform to extend into the position between the two lifting support platforms 121, so that one of the tray parking positions 42 is located directly below the tray body 2, and the lifting drive component 122 is controlled to drive the lifting support platform 121 to descend until the middle of the tray body 2 is docked on the tray stopping position, so that the conical limit block 123 is completely separated from the first limit hole 22, that is, the tray body 2 parked at the second docking station 12 is transferred to the tray parking position 42 of the accompanying platform 41.

[0052] In the above embodiment, when the tray body 2 stays at the second docking station 12, the lifting support platforms 121 on both sides are used to support the limiting ear plate 21 of the tray body 2, and the conical limiting block 123 is used to pass through the first limiting hole 22 for positioning.

By controlling the two lifting support platforms 121 to descend, the lifting support platforms 121 lose support for the ear plate of the tray body 2, and the conical limiting block 123 is separated from the first limiting hole 22, so that the tray body 2 can fall smoothly to the corresponding tray parking position 42, that is, the tray body 2 can move along the Y direction with the traveling body 4.

Since the travel of the telescopic cylinders is fixed, the corresponding tray clamping seat can be precisely moved to the corresponding docking station by simply positioning the starting and ending points of the travel of the telescopic cylinders, thereby achieving the clamping of the tray body 2 and the transfer between the docking stations. The telescopic cylinders mentioned above can be pneumatic cylinders, hydraulic cylinders, or electric cylinders.

[0057] As a preferred embodiment, the Y-direction and the reverse side of the Y-direction of the material tray body 2 are respectively provided with two or more second limiting holes 23, the first material tray clamping seat 141 and the second material tray clamping seat 151 have the same structure, the first material tray clamping seat 141 is provided with a clamping arm 1411 symmetrically arranged on the Y-direction and the reverse side of the Y-direction, and the clamping arm 1411 is provided with a protrusion 1412 corresponding one-to-one to the second limiting holes 23.
