Description

Technical Field

[0001] This utility model relates to the field of semiconductor chip processing technology, specifically a carrier device for cutting roll frame. Background Technology

[0002] The lead frame (lead frame) used in chip packaging primarily serves for electrical connection, heat dissipation, and mechanical support. The lead frame connects the internal circuitry of the chip to the external printed circuit board (PCB) via metal wires, forming an electrical loop for signal transmission and power delivery. Common materials are nickel-based alloys or copper alloys, manufactured through etching or stamping processes to ensure high-precision mating. The frame directly contacts the chip and disperses the heat generated during operation, using the high thermal conductivity of the metal to conduct heat to the external environment, reducing the chip's operating temperature and ensuring stability. As the chip carrier, it provides physical support and protects the chip from external impacts or vibrations, while also using a precision structure to position the chip and ensure packaging accuracy.

[0003] After the coiled material has carried the chip, it needs to be cut into several chip frames for subsequent molding and encapsulation. Currently, the carrier device on the cutting equipment cannot effectively remove debris after cutting. If it accumulates, it will affect the normal cutting of the blade, prevent it from cutting the frame, and damage the cutting edge.

[0004] In view of the above-mentioned prior art, it is desirable to provide a support device for cutting roll frame, which can effectively reduce the frequency of placing the plastic seal. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 As shown, a support device for cutting a roll frame includes a support base 1 and a lower cutter 2.

[0024] like Figure 2 and Figure 3 As shown, the support base 1 has a cuboid structure; one side of the support base 1 is the feed end 3, and the other side is the discharge end 4; the upper surface of the support base 1 is provided with a groove 5, and the side of the groove 5 near the feed end 3 is provided with an installation groove 6, which is used to install the lower cutter 2.

[0025] The bottom of the groove 5 is a slope 7, and the end of the slope 7 near the mounting groove 6 is the upper end, and the end of the slope 7 near the discharge end 4 is the lower end.

[0026] The support base 1 has a discharge channel 8 on the side wall of the discharge end 4. The discharge channel 8 is connected to the groove 5, and the bottom of the discharge channel 8 is on the extension surface of the inclined surface 7 or below the extension surface of the inclined surface 7. In this embodiment, the bottom of the discharge channel 8 is on the extension surface of the inclined surface 7.

[0027] The lower cutter 2 is installed in the mounting groove 6, and the cutting edge of the lower cutter 2 faces the discharge end 4.

[0028] When the aforementioned support device is in operation, the external feeding conveyor conveys the roll frame to the support base 1. When the ribs to be cut on the roll frame are directly below the upper cutter, the upper cutter cuts downwards. With the cooperation of the lower cutter 2, the roll frame is cut into a chip frame. Then, under the action of the external clamping device, it is transferred to the discharge conveyor and conveyed to the designated position. During the cutting process, the generated debris is discharged along the inclined surface 7 and the discharge channel 8, which ensures the quality of the product and improves the service life of the upper and lower cutters.

[0029] In this embodiment, the feed end 3, the discharge end 4, and the edge of the groove 5 near the discharge end 4 of the support base 1 are all chamfered to facilitate feeding and discharging, and to ensure smooth online conveying.

[0030] In this embodiment, as Figure 4 As shown, several limiting posts 9 are vertically rotatably provided on both sides of the groove 5 on the upper surface of the support base 1; this setting effectively limits the movement of the conveying frame of the roll to be cut, ensuring the accuracy of the cutting.

[0031] In this embodiment, mounting holes 10 are provided on both sides of the upper surface of the support base 1 for mounting guide columns, which facilitates the accurate vertical downward movement of the subsequent cutting blade.

[0032] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
