[0075] At this time, the welding platform part forms a relatively closed cavity with the cover 5, then the cover 5 is filled with nitrogen, and the welding platform plate 32 starts to heat up, and when the working temperature is reached, the first direction driving assembly and the second direction driving assembly work, so that the position of the chip substrate that needs to be pasted is aligned with the pasting hole in the middle of the cover 5, and then the pasting head sucks the chip from the chip placing table 12 to the pasting position to perform the pasting action. Then the welding platform module 3 aligns the next position of the chip substrate with the opening, and then circulates in turn until the pasting of the entire chip substrate is completed, and after the entire chip substrate is completed, the vacuum of the welding platform plate 32 is disconnected, then the track plate 351 is raised and the sealing plate 37 on the discharge side of the welding platform module 3 is lowered in height, then the discharge module 4 hooks out the chip substrate from the welding platform module 3, and finally the chip substrate is pushed out by the discharge conveying belt assembly 41.

[0076] Finally, it should be noted that in the description of the present application, it should be noted that the terms "vertical", "upper", "lower", "horizontal" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation of the present application.

[0077] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "set", "install", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0078] The above is only the preferred embodiment of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
