The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] like Figures 1 to 3 As shown, an embodiment of the present invention provides a device for unloading valve shafts and magnetic sheets after riveting, comprising an unloading frame 901 and an unloading robot 902 arranged on the unloading frame 901, the unloading frame 901 is provided with an empty tray station 903, an unloading station 904 and a stacking station 905, the unloading robot 902 is arranged between the empty tray station 903 and the unloading station 904, the unloading frame 901 is provided with a jacking module conveying assembly, the jacking module conveying assembly is provided with two jacking modules, namely a first jacking module and a second jacking module, the first jacking module is driven by the jacking module conveying assembly, and reciprocates between the empty tray station 903 and the unloading station 904, the second jacking module is driven by the jacking module conveying assembly, and reciprocates between the unloading station 904 and the stacking station 905, A first unloading tray support assembly is provided at the tray station 903, a unloading tray fixing assembly is provided at the unloading station 904, and a second unloading tray support assembly is provided at the stacking station 905. The first unloading tray support assembly is used to support the unloading tray 40 located above it, the first jacking module is used to take out the lowest unloading tray 40 at the empty tray station 903 and transport it to the unloading station 904, the unloading tray fixing assembly is used to position the unloading tray 40 delivered by the first jacking module, the unloading robot 902 is used to place the valve shaft and magnetic sheet riveted together on the carrier 201 on the unloading tray 40 at the unloading station 904, the second jacking module is used to take out the unloading tray 40 at the unloading station 904 and transport it to the stacking station 905, and the second unloading tray support assembly is used to support the unloading tray 40 located above it.

[0038] The above-mentioned unloading device of the present invention is provided with three stations, namely, an empty tray station 903, an unloading station 904 and a stacking station 905. The empty tray station 903 is used to place the stacked empty unloading trays 40, the unloading station 904 is used to take the riveted valve shafts and magnetic sheets from the conveyor line and put them into the unloading trays 40, and the stacking station 905 is used to stack the unloading trays 40 filled with valve shafts and magnetic sheets. One device realizes multiple functions. It is conducive to improving unloading efficiency.

[0039] When applying specific Figure 3 As shown, multiple empty unloading trays 40 are stacked on the empty tray station 903. The first lifting module moves upward to support multiple empty trays, the first unloading tray support assembly is released, and the first lifting module moves downward by the distance of a unloading tray 40. At this time, the unloading tray 40 located at the bottom moves to the bottom of the first unloading tray support assembly. Then, the first unloading tray support assembly supports multiple unloading trays 40 located above the first unloading tray support assembly, and the unloading tray 40 located below the first unloading tray support assembly is supported by the first lifting module. Then, the first lifting module transports the unloading tray 40 to the unloading station 904. Then, the first lifting module lifts the unloading tray 40 by a certain distance, and the unloading tray fixing assembly is used to position the unloading tray 40 sent by the first lifting module. The first lifting module descends and moves to the empty tray station 903, ready to re-transmit a new empty unloading tray 40 to the unloading station 904. At the unloading station 904, the unloading manipulator 902 places the valve shafts riveted with magnetic sheets sent by the carrier 201 into the unloading tray 40 one by one. When the unloading tray 40 is full, the second jacking module located at the unloading station 904 rises to support the unloading tray 40, the unloading tray fixing assembly releases the unloading tray 40, and the second jacking module descends to transport the unloading tray 40 to the stacking station 905. Then the second jacking module rises and raises the unloading tray 40 to above the second unloading tray support assembly. The second unloading tray support assembly supports the unloading tray 40, and the second jacking module descends and moves to the unloading station 904. It should be noted that when there are multiple feed trays 40 supported by the second feed tray support assembly stacked at the stacking station 905, the second jacking module first moves the supported feed tray 40 upwards until the feed tray 40 contacts with other feed trays 40, so that all the stacked feed trays 40 can be supported by the second jacking module. At this time, the second feed tray support assembly is released, and the second jacking module continues to jack up and lift all the feed trays 40 above the second feed tray support assembly. Then, the second feed tray support assembly supports the stacked feed trays 40, and the second jacking module descends and moves to the feed station 904.

[0040] From the above description, it can be seen that the two lifting modules can move synchronously. While the first lifting module transports the empty unloading tray 40 to the unloading station 904, the second lifting module can transport the unloading tray 40 filled with valve shafts and magnetic sheets to the stacking station 905.
