The worker then retrieves the assembled ejector tube 1 and furnace body 2.

[0071] The implementation principle of this application embodiment is as follows: The assembly equipment realizes the automated assembly of the ejector tube 1 and the furnace body 2 through the coordinated work of various devices. The feeding and conveying device 4 transports the placement base 3, which contains the ejector tube 1 and the furnace body 2, to the designated position. The transfer device 7 transfers the placement base 3 to the gluing device 5 for gluing. After gluing, it is transferred to the screw fastening device 6 for screw fastening. After fastening, the placement base 3 moves to the third fastening station 67 through the fastening platform 62. The return device 8 set on the third fastening station 67 clamps and slides the placement base 3 to the input end of the feeding and conveying device 4. At this time, since there is no pressure mechanism 63, the support spring in the placement base 3 restores its deformation and lifts the entire fastened ejector tube 1 and furnace body 2. At this time, the bottom of the ejector tube 1 separates from the snap-fit ​​post in the first placement seat 32. The entire ejector tube 1 and furnace body 2 are then hung on the second placement, which is convenient for workers to remove and place the ejector tube 1 and furnace body 2 to be assembled.
