It includes a frame, a transmission belt, an active roller and one or more driven rollers, the active roller and the driven roller are both installed inside the frame, the transmission belt is coiled on the active roller and one or more driven rollers, the middle of the active roller and the driven roller are both reduced inward to form a mounting portion, the mounting portion is installed with a first arc bevel gear, and a bearing is installed in the middle of the transmission belt.

[0003] In the above scheme, the wind energy during rotation can quickly and comprehensively dissipate the heat on the patch fixture, and the rotating patch fixture can effectively remove the residual impurities. However, in the above scheme, the patch is inserted into the slot body. When the slot body rotates, the patch inside it will be caused by the centrifugal force generated by the rotation of the slot body, causing one side of the patch to be tightly attached to the rubber layer on the inner wall of the slot body. At this time, when the slot body rotates, the impurities on the side of the patch that are tightly attached to the rubber layer will not be able to be thrown out, resulting in the impurities on the patch cannot be completely cleaned; for this reason, we provide a cooling rack for SMT patch fixtures to solve the above problems.
