[0025] In one embodiment of the present invention, Figure 1-3As shown, a tinning carrier includes a placement seat 1 and a placement plate 2, wherein the placement plate 2 is installed on the placement seat 1, and the placement plate 2 is provided with a placement groove 21, wherein the placement groove 21 is used to place the tinning workpiece; the placement groove 21 is provided with a positioning protrusion 211, a positioning convex strip 212 and a pin hole 213, wherein the positioning convex strip 212 is located between the two positioning protrusions 211, and the positioning protrusion 211 and the positioning convex strip 212 are used to make the pin of the tinning workpiece be located in the middle of the pin hole 213. In this embodiment, the number of the positioning protrusions 211 and the positioning convex strips 212 is two respectively, and the two positioning convex strips 212 are located between the two positioning protrusions 211. Three placement stations are formed between the two positioning protrusions 211 and the two positioning convex strips 212, and each placement station is penetrated by four pin holes 213. The tinning workpiece is specifically a transformer, and each transformer has four pins that need to be tinned. Positioning grooves corresponding to the ends of the positioning protrusions 211 or the positioning convex strips 212 are respectively provided on both sides of the insulating plate of the transformer. When working, the tinning workpiece is placed in the placement groove 21. Specifically, the three tinning workpieces are placed in the placement groove 21 through the two positioning protrusions 211 and the two positioning convex strips 212 and the positioning grooves at both ends of the insulating plate. The tin workpieces are placed in corresponding placement stations respectively, and under the action of the positioning protrusion 211, the positioning convex strip 212 and the positioning groove, each pin that needs to be tinned is located in the middle of the corresponding pin hole 213, thereby preventing the pin from contacting and fitting with the inner wall of the pin hole 213, which causes the accumulation of tin liquid during tinning, and thus avoiding the phenomenon of uneven tinning; the present application uses the placement seat 1, the placement plate 2, the placement groove 21, the positioning protrusion 211, the positioning convex strip 212 and the pin hole 213; so that the pin of the tinned workpiece is located in the middle of the pin hole 213, preventing the pin from contacting and fitting with the inner wall of the pin hole 213, which causes the accumulation of tin liquid during tinning, thereby avoiding the phenomenon of uneven tinning adhesion, which is beneficial to improving the quality of tinning.

In this embodiment, the positioning protrusion 211 is set as a cylindrical structure, and the two ends of the positioning convex strip 212 are respectively set as semi-cylindrical structures. Compared with the polygonal angular structure, this embodiment can avoid the phenomenon that the polygonal body with an angular structure will jam the tinning workpiece, making it difficult to pick up and place the tinning workpiece, through the curved surface structure of the cylinder, thereby improving the efficiency of picking up and placing the tinning workpiece.
