Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1, it is the utility model relates to a welding auxiliary assembly between lamps and lanterns base plate 1 and radiator 2, include: and a weight 3 for generating an average downward pressure on the lamp substrate 1.

Thus, the utility model discloses when carrying out welding operation between lamps and lanterns base plate 1 and radiator 2, except adopting firing equipment to realize heating radiator 2, still additionally increase balancing weight 3 so utilizes balancing weight 3 to produce balanced downward effort to lamps and lanterns base plate 1, thereby utilizes the extrusion to discharge air and scaling powder to reduce the welding void ratio, promote the quality of product.

The utility model discloses after offering about the slot among the cooperation background art, practice proves many times, can obtain completely and let the characteristic that welding between lamps and lanterns base plate 1 and the heat dissipation base has the low voidage. Compared with the prior art, the utility model discloses when carrying out the welding of low voidage, whole auxiliary assembly has simple structure, with low costs and easy operation's characteristics.

As a specific embodiment of the weight block 3, the weight block 3 is a copper plate, and the copper plate is formed with a relief groove 31 at a position corresponding to the lamp crystal grain 11, so that when the copper plate presses the lamp substrate 1, the lamp crystal grain 11 can be staggered, thereby preventing the crystal grain 11 from being damaged due to pressing.

As shown in fig. 1, the weight member 3 has an abutting edge 32 located around the yielding groove 31, and the abutting edge 32 abuts against the periphery of the lamp substrate 1, so that the abutting edge 32 is utilized to apply an acting force to the lamp substrate 1, thereby improving the characteristic of reducing the void ratio.

In this embodiment, the lamp substrate 1 is an aluminum substrate, but some other basic materials commonly used in the prior art may also be used.

As a more preferable embodiment, the welding auxiliary equipment further includes a fixing seat formed around the weight block 3 and used for fixing the weight block 3 and the lamp substrate 1 together.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
