[0002] In the current semiconductor packaging process, flip chip is a key process. It mainly involves flipping the chip on the frame or substrate, and then transporting it to the reflow oven for curing through the wire connecting machine. Once the flip chip production is completed, the wire connecting machine will transport the products from different flip chip stations to the sorting machine. The sorting machine will then send these products and products from different machines to the reflow oven for reflow processing.

[0003] At present, the connection machine mainly relies on the belts on both sides of the track for transmission during transportation, as shown in the attached manual. Figure 1 As shown. However, there are some problems with this transmission method. When the frame and substrate are thin, they may fall into the track during transmission, causing the material to fall, and then causing the entire product to be scrapped. This not only reduces production efficiency, but also brings considerable economic losses to the company. Therefore, solving this problem is of great significance to improving production efficiency and product quality. Summary of the invention
