[0033] Further, as Figure 7 and Figure 8 shown, the tray 1 is a rectangular plate, the middle of the tray 1 is hollow, the edge position of the hollow in the middle of the upper surface 14 of the tray is recessed inward to form an inlay groove 6, and a plurality of positioning posts 7 are arranged in the inlay groove 6.

[0034] Specifically, the middle of the tray 1 is hollowed out, and the hollowed-out shape is also rectangular. The edge position of the rectangular hollow is recessed inward to form an inlay groove 6, so that the fixing mold 2 can just be embedded into the inlay groove 6. As Figure 7 shown, 4 positioning posts 7 are arranged in the inlay groove 6, and the 4 positioning posts 7 are divided into two groups in pairs and are respectively arranged at opposite ends of the inlay groove 6.

[0035] Further, as Figure 6 shown, a plurality of positioning holes 8 are arranged on the fixing mold 2, the number of the positioning holes 8 is the same as the number of the positioning posts 7, the positions of the positioning holes 8 on the fixing mold 2 correspond to the positions of the positioning posts 7 on the tray 1, the positioning posts 7 can be inserted into the positioning holes 8, and the positioning posts 7 and the positioning holes 8 are in interference fit.

[0036] Specifically, 4 positioning holes 8 are provided, and the 4 positioning holes 8 are divided into two groups in pairs and are respectively arranged at opposite ends of the fixing mold 2. When the fixing mold 2 is embedded into the inlay groove 6 of the tray 1, the 4 positioning posts 7 can be inserted into the 4 positioning holes 8.

[0037] The cooperation between the positioning posts 7 and the positioning holes 8 realizes the positioning and fixing between the tray 1 and the fixing mold 2.

[0038] As an implementation manner, the number of the positioning posts 7 can also be 6, and the number of the positioning holes 8 is also 6. The 6 positioning posts 7 are divided into two groups of three, and the two groups of positioning posts 7 are respectively arranged at opposite ends of the inlay groove 6.

The two positioning posts 7 are respectively arranged at opposite ends of the embedding groove 6, and the two positioning holes 8 are respectively arranged at opposite ends of the fixed mold 2.

[0040] That is to say, the numbers of the positioning posts 7 and the positioning holes 8 are not fixed. Those skilled in the art can set them as needed.

After a defective product 13 on the fixed mold 2 is completed with wire repair, the upper clamping plate 3 and the lower clamping plate 4 slide together until the next defective product 13, causing the next defective product 13 to be exposed from the window 9, and then continuing with the wire repair of the second defective product 13.

[0049] Furthermore, an installation groove 12 is provided on the lower surface 18 of the lower clamping plate.

[0050] The tooling of the present utility model is installed on the wire bonding station of a wire bonding machine to perform wire bonding repair on defective products 13.
