Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor chips, in particular to a rib cutting structure for semiconductor chip production. Background Art

[0002] Semiconductor chips are semiconductor devices that can achieve certain functions by etching and wiring on semiconductor sheets. However, after the packaging process, semiconductor chips still need to undergo a series of operations, such as post-curing, rib cutting, molding and electroplating. The rib cutting process usually involves cutting off the pins on the outside of the semiconductor, and the rib cutting structure produced by semiconductor chips is often used to achieve alignment and cutting of the pins.

[0003] However, most of the existing cutting structures select the corresponding cutting tool according to the semiconductor chip model for cutting. The cutting structure is difficult to cut different semiconductor chips according to the needs, resulting in certain limitations in the use of the device; in addition, after the semiconductor chip is cut, the semiconductor chip is often stuck in the cutting base and difficult to be quickly removed, thereby affecting the processing efficiency of the device. In summary, the existing semiconductor chip cutting structure still has the following problems:

[0004] 1. The cutting structure makes it difficult to cut different semiconductor chips according to needs, resulting in certain limitations in the use of the device; 2. The semiconductor chip is easily stuck in the cut base after cutting and is difficult to be quickly removed, affecting the processing efficiency of the device. Utility Model Content

[0005] The main purpose of the utility model is to provide a cutting rib structure for semiconductor chip production, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A rib cutting structure for semiconductor chip production comprises a mounting base, a mounting plate is fixedly mounted on the left and right ends of the mounting base, a support base is fixedly mounted on the front of the upper end of the mounting base, an ejection device is fixedly mounted on the lower inner wall of the support base, a cutting device is fixedly mounted on the upper end of the support base, a supporting device is fixedly mounted on the rear of the upper end of the mounting base, a No. 1 hydraulic cylinder is fixedly mounted on the front of the upper end of the supporting device, and a mounting frame is fixedly mounted on the lower end of the No. 1 hydraulic cylinder.

[0008] Preferably, the cutting device includes a cutting base, a chip card slot is provided in the middle of the upper end of the cutting base, a cutting notch is provided in the upper end of the cutting base, a No. 1 through hole is provided in the middle of the lower end of the cutting base, two No. 1 screws are installed at the left and right ends of the cutting base, the cutting base is fixedly mounted on the upper end of the support base by the No. 1 screws, two No. 2 screws are installed at the left and right ends of the mounting frame, a cutting head is installed at the lower end of the mounting frame, and a cutting blade is fixedly mounted at the lower end of the cutting head. The cutting head can be removed by loosening the No. 2 screws, and similarly, the cutting base can be removed by loosening the No. 1 screws. At this time, the corresponding model of the cutting base and the cutting head can be installed as needed, so that the device can cut ribs for chips of different models, thereby improving the practicality of the device.

[0009] Preferably, the ejection device comprises a No. 2 hydraulic cylinder, a mounting groove is formed in the middle of the front end of the support seat, a No. 2 through hole is formed in the middle of the upper end of the support seat, and the No. 2 hydraulic cylinder is fixedly mounted on the lower inner wall of the mounting groove. The No. 2 hydraulic cylinder drives the piston rod at its output end to extend and retract, and the piston rod then ejects the chip in the chip slot through the No. 2 through hole and the No. 1 through hole, so as to facilitate the unloading of the chip after the rib cutting.

[0010] Preferably, the supporting device comprises a fixing plate, a No. 1 supporting column is fixedly mounted on the upper end of the fixing plate, a No. 2 supporting column is fixedly mounted on the upper outer surface of the No. 1 supporting column, and the fixing plate is fixedly mounted on the rear portion of the upper end of the mounting base.

[0011] Preferably, the cutting blades have cutting notches of the same size and corresponding positions up and down.

[0012] Preferably, the support seat is in a U-shape.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When it is necessary to cut off the outer pins of the chip, first place the chip in the chip slot on the cutting base on the cutting device. The chip slot is consistent with the chip size, and then the chip is clamped in the chip slot. Then, the mounting frame at the lower end is driven downward by the No. 1 hydraulic cylinder, and the mounting frame then drives the cutting head downward, and finally the cutting blade is moved into the cutting notch, thereby cutting off the outer pins of the chip. When the device needs to cut ribs for chips of different models, the cutting head can be removed by loosening the No. 2 screw. Similarly, the cutting base can be removed by loosening the No. 1 screw. At this time, the cutting base and cutting head of the corresponding model can be installed as needed, so that the device can cut ribs for chips of different models, thereby improving the practicality of the device.

[0015] 2. After the chip is cut, it is clamped in the chip slot. When it is inconvenient to remove it manually, the No. 2 hydraulic cylinder on the ejection device drives the piston rod at its output end to extend and retract. The piston rod then ejects the chip in the chip slot through the No. 2 through hole and the No. 1 through hole, making it easier to remove the chip after rib cutting.
