Technical Field
[0001] The utility model belongs to the technical field of semiconductor plastic packaging molds, and particularly relates to an elastic supporting floating frame. Background Art
[0002] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, in the semiconductor plastic encapsulation process, a support frame is usually used to place the lead frame into the mold, and the main component of the support frame that carries the lead frame is the floating frame. The floating frame is rectangular in shape and has several support arms extending inward. The number of support arms varies depending on the lead frame structure. Four or more support arms on each floating frame are also equipped with positioning pins to position the two lead frames on the floating frame.
[0003] During the semiconductor plastic packaging process, some lead frames are large in size and thin in thickness. The commonly used floating frames cannot support the lead frames, or the lead frames are easily dropped during the process of being transported to the mold. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an elastic supporting floating frame to address the deficiencies in the above-mentioned prior art, solve the problem of using a floating frame to bear the weight of a large-sized, thin, and soft lead frame, and overcome the influence of the supporting frame and the floating frame on the position of the lead frame during the change of hot and cold states, so that the lead frame can be placed in the mold more accurately.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an elastic material supporting floating frame, comprising a floating outer frame and one or more material supporting components installed on the floating outer frame, wherein the material supporting components include a steel wire, a limit head and a tightening degree adjuster;
[0006] The two ends of the steel wire are installed between the two side ribs of the floating outer frame through the limit heads, and the tightening degree adjuster is used to keep the steel wire in a taut and straight state.
[0007] The elastic material supporting floating frame has a plurality of material supporting arms extending inwardly on the inner side of the floating outer frame, and the material supporting assembly is installed between the material supporting arms opposite to each other between the two side ribs;
[0008] The two supporting arms for installing the supporting assembly are provided with clearance grooves, and the two ends of the steel wire are respectively passed through the clearance grooves of the two supporting arms and connected with the limit heads.
[0009] The above-mentioned elastic supporting floating frame, one end of the steel wire passes through the yield groove of one supporting arm to the side ridge of the floating outer frame and is connected with a limit head, and the limit head is installed at the side ridge; the other end of the steel wire passes through the yield groove of another supporting arm to the outside of another side ridge and is connected with another limit head, and a tightening adjuster is installed between the limit head and the side ridge.
[0010] The elastic supporting floating frame, the tightening degree adjuster is a compression spring, the compression spring is passed through the steel wire and clamped between the limit head and the side rib.
[0011] The above-mentioned elastic support floating frame, the give way groove extends from the support arm to the side ridge of the floating outer frame, the give way groove on one side ridge is installed with a pressure plate to limit the compression spring to the outside of the side ridge, and the give way groove on the other side ridge is installed with a pressure plate to clamp the limit head at the give way groove.
[0012] Compared with the prior art, the utility model has the following advantages: when the floating frame carries a large-size, thin and soft lead frame, the steel wire in the supporting component is at the bottom of the lead frame to support it.
[0013] When the floating frame changes between hot and cold states, its size changes slightly. The compression spring adjusts the steel wire in the supporting assembly through elastic force to keep it in a straight state, thereby supporting the lead frame. The elastic force of the compression spring is extremely small and will not cause the floating frame to deform, thereby affecting the accuracy of placing the lead frame into the mold.
[0014] The technical solution of the utility model is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
