Description

Technical Field

[0001] This utility model relates to the field of carrier tape cutting technology, and in particular to a cutting device for carrier tape used in electronic component packaging. Background Technology

[0002] The carrier tape cutting device for electronic component packaging is mainly used to precisely cut the carrier tape to meet the specifications of electronic component packaging. As a key piece of equipment in carrier tape packaging, its role is not limited to physical cutting, but also lays the foundation for subsequent processes through standardized cutting. For example, carrier tape of uniform specifications can match the parameters of automated packaging machines, reducing debugging time, while also facilitating inventory management (such as categorizing and storing by cut length), improving supply chain efficiency. In short, through precise cutting, efficient production, and quality control, this device has become a core piece of equipment in the electronic component packaging process to ensure product consistency and production efficiency.

[0003] However, existing technologies, such as Chinese Publication No. CN222494429U, "A Cutting Device for Carrier Tape for Electronic Component Packaging," relate to the field of carrier tape cutting and disclose a cutting device for carrier tape for electronic component packaging. This device includes a cutting table, with a mounting mechanism, a limiting frame, and two fixed frames sequentially fixed to the top of the cutting table. A U-shaped frame is provided within the inner cavity of the limiting frame, and a pressure roller is rotatably mounted within the inner cavity of the U-shaped frame. The pressure roller is mounted within the inner cavity of the U-shaped frame via a rotating shaft, and a handle is fixedly connected to the outer ring of one end of the rotating shaft. In this cutting device, the carrier tape reel is fixed using the mounting mechanism, the U-shaped frame is moved upwards to pull out the carrier tape, which passes through the bottom of the pressure roller and is pressed and limited by a spring on the outer ring of a telescopic rod. The position of the adjusting plate is adjusted using an adjusting block within the fixed frame according to the cutting length, and the pressure roller on the rotating shaft is rotated using the handle.

[0004] However, this device does not have a moving linkage cutting structure, so it cannot adapt to the dynamic cutting requirements during the carrier tape transmission process. It cannot solve the limitations of traditional fixed cutting structures in terms of accuracy, efficiency and adaptability. It cannot solve the speed matching problem between carrier tape transmission and cutting, and cannot achieve accuracy assurance, efficiency improvement and flexible adaptation. Under the trend of miniaturization of electronic components and production automation, it is not suitable for scenarios with strict requirements for accuracy and production capacity.

The stabilizing sleeve makes the lifting frame more stable during lifting.

[0013] In a preferred embodiment, a limiting groove is provided on the pressure-bearing shell, and a cutting hole is provided inside the limiting groove, through which the carrier tape to be cut is passed.

[0027] like Figures 1 to 5 As shown, a follower rod 10 is provided inside the one-way crank 9. A take-up reel 11 is fixedly connected to the end of the follower rod 10 away from the one-way crank 9. Each time the one-way crank 9 swings back and forth, it will drive the follower rod 10 and the take-up reel 11.

[0028] like Figures 1 to 5 As shown, a side plate 12 is rotatably connected to the outer surface of the follower rod 10. The bottom of the side plate 12 is fixedly connected to the top of the pressure shell 1. A guide tube 13 is rotatably connected to the side of the side plate 12 near the winding coil 11. The other end of the first connecting rod 8 will drive the follower rod 10 to rotate inside the side plate 12 through the one-way crank 9.

[0029] like Figures 1 to 5 As shown, an eccentric wheel 14 is fixedly connected to the end of the power rod 3 away from the adjusting plate 4. The second connecting rod 15 is rotatably connected to the side of the eccentric wheel 14 away from the power rod 3. The shaft block 16 is rotatably connected to the end of the second connecting rod 15 away from the eccentric wheel 14. At the same time, the eccentric wheel 14, which rotates with the power rod 3, will drive one end of the second connecting rod 15.

[0030] like Figures 1 to 5 As shown, a lifting frame 17 is fixedly connected to the top of the shaft block 16. The outer surface of the lifting frame 17 is movably embedded in the top of the pressure shell 1. A cutting block 18 is fixedly connected to the bottom of the lifting frame 17.

One side of the stabilizing sleeve 19 is fixedly connected to the outer surface of the pressure shell 1.

[0032] like Figures 1 to 5 As shown, a limiting groove 20 is provided on the pressure shell 1, and a cutting hole 21 is provided inside the limiting groove 20. The carrier belt that needs to be cut is passed through the limiting groove 20 on the pressure shell 1.

[0033] like Figures 1 to 5 As shown, a motor 22 is fixedly connected to the inner surface of the pressure shell 1. A drive wheel 23 is fixedly connected to the output end of the motor 22. A synchronous belt 24 is driven to the outer surface of the drive wheel 23. A driven wheel 25 is driven to the inner surface of the synchronous belt 24 away from the drive wheel 23.

[0034] Working principle: First, the carrier tape to be cut is passed through the limiting groove 20 on the pressure shell 1 and wound around the outer surface of the take-up roll 11 through the guide tube 13. Then, the center distance of the internal thread block 7 is adjusted according to the required cutting spacing of the carrier tape. The screw rod 5 is rotated inside the adjusting plate 4 by the knob 6. The rotation of the screw will drive the internal thread block 7, causing the internal thread block 7 to move inside the adjusting plate 4 and change the center distance of the internal thread block 7. Then, the external power supply of the motor 22 is turned on. After the motor 22 is powered on, it will drive the drive wheel 23 to rotate. At the same time, under the transmission action of the synchronous belt 24 on the driven wheel 25, the power rod 3 is driven to rotate inside the shaft plate 2. The adjusting plate 4 and the internal thread block 7 rotate with the power rod 3. This will drive one end of the first connecting rod 8, and the other end of the first connecting rod 8 will drive the follower rod 10 to rotate inside the side plate 12 through the one-way crank 9. Because the one-way crank 9 is an existing device and technology, it can only effectively transmit unidirectional rotation. This causes the follower rod 10 and the take-up coil 11 to rotate in one direction each time the one-way crank 9 swings back and forth. At the same time, the eccentric wheel 14 that follows the rotation of the power rod 3 will drive one end of the second connecting rod 15. The other end of the second connecting rod 15 will drive the lifting frame 17 to rise and fall on the top of the pressure shell 1 through the shaft block 16. The stabilizing sleeve 19 can make the lifting frame 17 rise and fall more stably.
