[0034] Reference Figure 1 , Figure 2 and Figure 4A potting device for aluminum nitride ceramic substrates used in rectifiers is described in this embodiment. Compared to Embodiment 1, the potting liquid storage mechanism 6 includes a bottom end plate 61, a push-telescopic cylinder 62, an outer end plate 63, rolling ball bearings 64, a corrugated telescopic tube 65, an extraction pipe 66, a storage box 67, and a box cover 68.

Rolling ball bearings 64 are rotatably mounted on the inner side of the outer end plate 63, allowing the storage box 67 to roll and move its position via the rolling ball bearings 64 in the outer end plate 63. The bottom end plate 61 is fixedly connected to the lower front end of the storage box 67. A push-telescopic cylinder 62 is screwed onto the inner end of the bottom end plate 61. The push-telescopic cylinder 62 is mounted on the potting machine housing 4 and pushes... When the telescopic rod of the telescopic cylinder 62 extends, it drives the bottom end plate 61 to move forward. The bottom end plate 61 then drives the storage box 67 to move forward. A box cover 68 is rotatably installed on the upper front side of the storage box 67. When the box cover 68 is rotated open, potting fluid can be added to the storage box 67. An extraction pipe 66 is fixedly connected to the upper rear side of the storage box 67. A corrugated telescopic tube 65 is screwed on the outer end of the extraction pipe 66.

Then, potting fluid can be extracted for potting. The corrugated telescopic tube 65 is a telescopic structure, so it can expand and contract during movement to avoid obstruction when exposed.

[0035] The outer end plate 63 makes rolling contact with the potting machine housing 4 through the rolling ball 64, thereby allowing it to roll and move.

[0036] Working principle: During use, the operator places the rectifier aluminum nitride ceramic substrate workpiece 7 onto the belt conveyor body 5, allowing the workpiece 7 to move from left to right along the belt conveyor body 5 for potting. The workpiece 7 moves into the internal dustproof box 1, which effectively blocks external dust. The moving potting mechanism 2 extracts potting liquid from the potting liquid storage mechanism 6, allowing the moving rectifier aluminum nitride ceramic substrate workpiece 7 to be potted. After potting, the workpiece 7 moves to a position where it is detected by the infrared sensors 8 when it passes between the two infrared sensors 8, thus stopping the entire process. The operator then opens the internal dustproof box 1 to retrieve the corresponding potted rectifier aluminum nitride ceramic substrate workpiece 7 for trimming, preventing installation problems caused by excessive potting height during later installation.
