Abstract: The present invention provides a method for bonding a heat sink in a multi-negative pressure environment, comprising the following steps placing a workpiece with a retaining wall structure in a lower jig; supplying adhesive to a surface of the workpiece within an area surrounded by the retaining wall structure; using an upper jig to pick up the heat sink and aligning it with the lower jig to form first closed space; evacuating the first closed space to create a first negative pressure environment; positioning the heat sink onto the retaining wall structure to form second closed space; bonding the heat sink to the workpiece, during which at least one gap is formed; continuing to apply pressure to the heat sink, creating a negative pressure within the gap; and restoring negative pressure environments to atmospheric pressure, allowing the adhesive to fill the gap. This method eliminates gaps during bonding.

Abstract: The present invention provides a method for bonding a heat sink, which includes the following steps: placing a workpiece in a lower jig; supplying an adhesive to a surface of the workpiece; after a suction head of an upper jig picks up the heat sink, moving the upper jig to assemble with the lower jig to form a closed space; evacuating the closed space to create a negative pressure environment; driving the suction head toward the workpiece and bonding the heat sink to the workpiece, during which at least one gap is formed between the heat sink and the adhesive; continuing to drive the suction head to apply pressure to the heat sink, creating a negative pressure within the gap; and restoring the negative pressure environment to atmospheric pressure, allowing the adhesive to fill the gap. The invention effectively resolves the issue of gaps forming during the bonding process.

Abstract: A spray nozzle assembly includes a spray nozzle having a tapered alignment portion and an air nozzle having a tapered alignment recess. When the spray nozzle is placed in the air nozzle, an inner conical surface defined around the alignment recess abuts on an outer conical surface of the alignment portion. With the inner conical surface and the outer conical surface, the spray nozzle is able to slide with respect to the air nozzle to a predetermined position automatically. The spray nozzle and the air nozzle can be connected with each other without threaded structure, and gap and tolerance therebetween can be reduced. Accordingly, concentricity between the spray nozzle and the air nozzle is high, such that gel can be sprayed evenly.

Abstract: A spray valve has a valve body, a moving pin, an air-passage seat, and a nozzle structure. The moving pin is mounted within the valve body, is linearly movable relative to the valve body, and has an impact end. The air-passage seat has a connecting portion screwed onto the valve body and a positioning groove. The nozzle structure has a nozzle seat and a spray nozzle. The nozzle seat is movably accommodated in the positioning groove. The spray nozzle is in sliding fit with the nozzle seat and has a positioning conical portion. The positioning conical portion corresponds to the impact end of the moving pin and is configured to contact the impact end of the moving pin.
