[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:
[0023] A carrier tape cutting assembly for carrier tape production, including a cutting knife mechanism base plate 1. A first fixing block 2 is fixedly connected to the surface of the cutting knife mechanism base plate 1. A cylinder 3 is fixedly connected to the surface of the first fixing block 2. The output end of the cylinder 3 is fixedly connected to a cutting knife adjusting rod 4. A cutting knife 5 is fixedly connected to the surface of the cutting knife adjusting rod 4. A fixing plate 6 is fixedly connected to the surface of the cutting knife mechanism base plate 1. A second fixing block 7 is fixedly connected to the surface of the fixing plate 6. A feeding port 8 is opened on the surface of the second fixing block 7. A stop block 9 is fixedly connected to the surface of the fixing plate 6. A cutting groove 10 is opened on the surface of the stop block 9. A rotating shaft 11 is fixedly connected inside the second fixing block 7. A roller 12 is movably connected to the surface of the rotating shaft 11. A limiting rod 13 is movably connected inside the cutting knife 5. A pressing plate 14 is fixedly connected to the surface of the limiting rod 13. A spring 15 is fixedly connected to the surface of the pressing plate 14. This cutting assembly is installed at the front end of the receiving port of the carrier tape forming machine. The cylinder 3 is controlled by an electromagnetic valve, and the cylinder 3 controls the cutting knife 5 to cut the carrier tape, making the meterage of the carrier tape controllable and more accurate. After the carrier tape reaches the specified meterage, the cylinder 3 is ventilated, and the cutting knife 5 moves towards the stop block 9 through a slide rail. When it moves to the cutting groove 10, the carrier tape is cut, making the meterage of the carrier tape meet the requirements. A pressing plate 14 is arranged in parallel beside the cutting head of the cutting knife 5. The pressing plate 14 is connected to the surface of the cutting knife 5 through a spring 15. When the cutting knife 5 performs the carrier tape cutting operation, the pressing plate 14 touches the carrier tape before the cutting head. Under the action of the spring 15, the pressing plate 14 presses and fixes the carrier tape to prevent the carrier tape from moving during cutting, resulting in an uneven cut. At the same time, a cutting groove 10 is opened on the surface of the stop block 9. When the cutting knife 5 performs the cutting operation, it moves to the cutting groove 10 to cut the carrier tape, and the cutting head does not contact the stop block 9, reducing the damage to the cutting head and increasing the service life. A roller 12 is arranged at the feeding port 8, making the feeding more stable.
[0024] Further, the cutting knife mechanism base plate 1, the first fixing block 2, the cylinder 3, the fixing plate 6, the second fixing block 7, and the stop block 9 are all fixedly connected through bolts and threaded holes opened on their surfaces, making the installation and disassembly of this cutting assembly simple and convenient.
[0025] Further, a slide rail is opened on the surface of the fixing plate 6. The shape and size of the slide rail correspond to those of the cutting knife 5. The cutting knife 5 moves inside the slide rail to perform the cutting operation.
[0026] Further, the cutting head of the cutting knife 5 does not contact the inner wall of the slide rail. The height of the cutting groove 10 is equal to the height of the cutting head of the cutting knife 5. When the cutting knife 5 performs the cutting operation, the cutting head can be inserted into the cutting groove 10.
[0027] Further, circular grooves 1 with the same size and shape as the roller 12 are opened on both sides of the feeding port 8. Both ends of the rotating shaft 11 are fixed on the inner walls of the circular grooves 1. A part of the roller 12 protrudes from the circular grooves 1 into the feeding port 8. The surface of the roller 12 contacts the surface of the carrier tape, making the feeding more stable.
[0028] Further, the limiting rod 13 is arranged parallel to the cutting head of the cutting knife 5. Two groups of second circular grooves are vertically opened on the arc surface at the cutting head of the cutting knife 5. One group of the limiting rods 13 is movably connected in each of the two groups of second circular grooves. One end of the spring 15 is fixedly connected to the surface of the pressing plate 14, and the other end of the spring 15 is fixedly connected to the arc surface at the cutting head of the cutting knife 5. The diameter of the spring 15 is larger than that of the limiting rod 13. The spring 15 is sleeved outside the limiting rod 13 and the spring 15 does not contact the limiting rod 13. The limiting rod 13 ensures that the pressing plate 14 always moves parallel to the cutting head of the cutting knife 5.
[0029] Further, the surface of the pressing plate 14 close to the cutting groove 10 is provided with S-shaped anti-slip bumps. When the spring 15 is in a natural state, the end of the limiting rod 13 away from the pressing plate 14 is still in the second circular groove. The pressing plate 14 is closer to the cutting groove 10 than the cutting head of the cutting knife 5. When the cutting knife 5 performs the operation of cutting the carrier tape, the pressing plate 14 touches the carrier tape before the cutting head. Under the action of the spring 15, the pressing plate 14 presses and fixes the carrier tape.
[0030] Working principle: The cutting assembly is fixed on the equipment through the cutting knife mechanism bottom plate 1. The cutting knife 5 is connected to the air cylinder 3 by the cutting knife adjusting rod 4 and is driven by the air cylinder 3. The cutting knife 5 moves in the slide rail to the cutting groove 10 to complete the cutting of the carrier tape. Before using the cutting assembly, first adjust the positions among the cutting knife adjusting rod 4, the air cylinder 3 and the cutting knife 5 to make the cutting knife 5 in a relatively safe position before working. And through the adjustment of the air cylinder 3, the cutting knife 5 can accurately move to the cutting groove 10 on the stop block 9 through the slide rail. The carrier tape is fed into the cutting assembly from the feed port 8. The rollers 12 are arranged on both sides of the feed port 8, and their surfaces are in contact with the surface of the carrier tape, making the feeding smoother. The pressing plate 14 on the cutting knife 5 touches the carrier tape before the cutting head. Under the action of the spring 15, the pressing plate 14 presses and fixes the carrier tape. The surface of the pressing plate 14 is provided with S-shaped bumps, increasing the friction between the pressing plate 14 and the surface of the carrier tape and preventing the carrier tape from moving during cutting, resulting in an uneven cut. The cutting of the carrier tape is completed. The cutting head of the cutting knife 5 does not directly contact the stop block 9, preventing the cutting head from being damaged and increasing the service life. The slide rail plays a guiding role in carrying the cutting knife 5, enabling the cutting knife 5 to accurately and stably perform the cutting function. The cutting knife mechanism bottom plate 1 and the fixing plate 6 are provided with a discharge port on the surface corresponding to the feed port 8. The cut carrier tape is discharged from the discharge port.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
