Description

Technical Field

[0001] The utility model relates to the technical field of trimming devices, in particular to a COT fixture trimming device. Background Art

[0002] A COT (Chip On Tape) fixture is a special tool used in the chip packaging and manufacturing process. It is mainly used to fix, position, and transfer the chip to the tape during the chip mounting process to ensure that the chip can be accurately placed on the tape and remain stable during subsequent processing, testing, and transportation.

[0003] In the COT process, there are often components that require precise edge cutting, such as tape with chips attached. The trimming device removes excess material to ensure the product meets the specified dimensional accuracy requirements. However, current COT fixture trimming devices have a high defect rate, hindering product quality reliability and production efficiency.

[0004] In response to the above problems, this utility model document proposes a COT fixture cutting device. Utility Model Content

[0005] The utility model provides a COT fixture trimming device, which solves the shortcomings of the prior art COT fixture trimming device in that the defect rate is high when in use, which is not conducive to improving product quality reliability and production efficiency.

[0006] The utility model provides the following technical solutions:

[0007] COT fixture trimming device, including:

[0008] A base plate, a quick clamp for pressing a workpiece to be processed is installed on the top of the base plate, a pressing block is fixedly provided on the pressing end of the quick clamp, a mounting frame is fixedly provided on the top of the base plate, a cylinder is fixedly provided on one side of the mounting frame, an output end of the cylinder passes through the mounting frame and is fixedly provided with a blade holder, and a blade is provided on the blade holder;

[0009] The positioning component is arranged on the base plate and is used to limit the position of the workpiece.

[0010] In a possible design, a guide rod for improving the movement stability of the blade holder is fixedly provided on the top of the base plate, and the bottom of the blade holder is slidably mounted on the top of the guide rod.

[0011] In one possible design, the positioning assembly includes a side abutment plate fixedly arranged on the top of the base plate, one side of the side abutment plate is aligned with one side of the guide rod, a thin plate for pressing the workpiece to be processed is laid between the base plate and the pressure block, and the oblique edge of the thin plate is aligned with one side of the side abutment plate.

[0012] In a possible design, the blade in the blade holder mounting opening is fixed by a mounting bolt so as to be disassembled and replaced.

[0013] In a possible design, the quick clamp and the pressing block are arranged to be laterally inclined to facilitate observation of the workpiece to be processed.

[0014] In a possible design, the pressing block is made of a metal material with high density.

[0015] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0016] The working principle and usage process of this technical solution are as follows:

[0017] When in use, place the COT jig on the base plate, use the side abutment plate in the positioning assembly to press one side of the COT jig against the side abutment plate to limit its horizontal movement, and press the thin plate onto the COT jig so that its bevel edge is aligned with one side of the side abutment plate and pressed tightly against the COT jig to further enhance the positioning effect. Afterwards, adjust the position of the quick clamp so that its pressing end is aligned with the COT jig to be processed. By operating the quick clamp, the pressing block is pressed tightly against the thin plate using its pressing force to ensure that the COT jig does not move during the cutting process.

[0018] After fixing the COT jig, connect the air inlet and outlet of the cylinder device to the air pipe. After starting the air compressor, the output end of the cylinder pushes the blade holder to slide along the guide rod until the blade touches the edge of the COT jig. The cylinder continues to push the blade holder to move along the predetermined cutting path to complete the trimming operation. During the cutting process, the quick clamp and pressure block are tilted to better observe the cutting condition of the COT jig. After the cutting is completed, turn off the cylinder to return the blade holder to its initial position. After releasing the quick clamp, remove the processed COT jig. If the blade needs to be replaced, it can be easily completed by removing the mounting bolts.

[0019] The utility model has the following beneficial effects:

[0020] The utility model can accurately limit the position of the COT jig by setting a positioning component to prevent it from moving during the cutting process, thereby improving the cutting accuracy. The position limitation function can facilitate the operator's loading and unloading, save process time, improve production efficiency, and reduce work errors.

[0021] The inclined quick clamp and pressure block of the utility model make it easy for the operator to observe the cutting situation of the COT fixture, thereby improving the convenience and accuracy of the operation. By designing the automatic cutting system of the cylinder, the cutting size of each COT fixture is better guaranteed, the product quality is guaranteed, and the automatic cutting saves the time of the process, saves time and labor, and improves work efficiency and customer competitiveness.

[0022] In the utility model, the blade holder slides along the guide rod to ensure the straightness and stability of the cutting path, and the blade is fixed by mounting bolts, which is convenient for disassembly and replacement, thereby reducing maintenance costs.
