Referring to the above work conveying process, the first jig needs to convey the second jig empty on the fourth conveying platform 4 to the first conveying platform 1 in the process of the second conveying platform 2 for blanking operation, and because the first conveying platform 1, the fourth conveying platform 4 and the second conveying platform 2 are synchronously driven by the conveying driving device 7, the first jig which is not yet blanked is conveyed to the fourth conveying platform 4 by the second conveying platform 2 under the driving of the conveying driving device 7 in the process of conveying the second jig from the fourth conveying platform 4 to the first conveying platform 1, thereby damaging the blanking operation.
To avoid this problem, in this embodiment, by providing the jacking device 9 and the first sensing device, when the first jig reaches the second conveying platform 2, the jacking device 9 may be automatically triggered to jack the first jig, so as to separate the first jig from the second conveying platform 2, specifically, separate the first jig from the second roller 21, and then perform the blanking operation; so the first jig can not be influenced by the conveying action of the second conveying platform 2 in the blanking process, and the smooth completion of the blanking operation is ensured; after the blanking is completed, the jacking device 9 can be triggered to lower the first jig so that the first jig is contacted with the second conveying platform 2 again, specifically, the first jig is contacted with the second roller 21, so that the subsequent action of conveying the empty first jig to the fourth conveying platform 4 is completed.

9. A workpiece conveying method, characterized in that the workpiece conveying method is performed using the workpiece conveying apparatus according to any one of claims 1 to 8; the workpiece conveying method comprises the following steps:
s1, carrying out feeding operation on the first jig positioned on the first conveying platform;
s2, driving the first jig after loading to be sequentially conveyed to the second conveying platform by the first conveying platform and the third conveying platform, and carrying out blanking operation on the first jig positioned on the second conveying platform;
s3, driving the third conveying platform and the fourth conveying platform to move along the height direction through the lifting device so as to enable the fourth conveying platform to be in butt joint with the first conveying platform and the second conveying platform;
s4, driving the second jig to be conveyed to the first conveying platform by the fourth conveying platform, and carrying out feeding operation on the second jig positioned on the first conveying platform;
s5, driving the first jig after blanking to be conveyed to the fourth conveying platform by the second conveying platform;
s6, driving the third conveying platform and the fourth conveying platform to move along the height direction through the lifting device so as to enable the third conveying platform to be in butt joint with the first conveying platform and the second conveying platform;
S7, driving the second jig after loading to be sequentially conveyed to the second conveying platform by the first conveying platform and the third conveying platform, and carrying out blanking operation on the second jig positioned on the second conveying platform;
s8, driving the third conveying platform and the fourth conveying platform to move along the height direction through the lifting device so as to enable the fourth conveying platform to be in butt joint with the first conveying platform and the second conveying platform;
s9, driving the first jig to be conveyed to the first conveying platform by the fourth conveying platform, and carrying out feeding operation on the first jig positioned on the first conveying platform;
s10, driving the second jig after blanking to be conveyed to the fourth conveying platform by the second conveying platform;
s11, driving the third conveying platform and the fourth conveying platform to move along the height direction through the lifting device so as to enable the third conveying platform to be in butt joint with the first conveying platform and the second conveying platform;
s12, repeating the steps S2-S11.
10. The workpiece conveying method according to claim 9, wherein the second conveying platform is provided with a jacking device;
Before the step S4, the method includes:
s04, driving the first jig to move upwards through the jacking device so as to separate the first jig from the second conveying platform;
and/or, before the step S9, the method includes:
s09, driving the second jig to move upwards through the jacking device so as to separate the second jig from the second conveying platform.
