[0002] Carrier tape is a strip product widely used in the field of electronic packaging. It has a specific thickness and has holes for holding electronic components and positioning holes for index positioning evenly distributed along its length. The main purpose of the carrier tape is to be used with a cover tape to carry and store electronic components such as resistors, capacitors, transistors, and diodes in the pockets of the carrier tape.

[0004] The prior art patent document with publication number CN219805275U provides a carrier cutting device, which can limit the moving path of the carrier through the setting of a limiting guide rail so that it can move smoothly to the cutting component. Through the setting of the loading component, after one end of the carrier is inserted between the two sets of limiting guide rails, the loading component can drive the carrier to move between the two sets of limiting guide rails. After moving it to the cutting component, the cutting component can cut the carrier. This device can achieve the purpose of uninterrupted conveying of the carrier to facilitate its efficient cutting.

When encountering carriers of different widths, it cannot be moved, and then the carriers of different widths cannot be adjusted, which reduces the efficiency of carrier cutting. Therefore, we need a carrier cutting device. Utility Model Content

[0028] The mounting assembly 8 includes a positioning groove 801, the inner wall of which is snap-connected with a positioning rod 802, and one side of the positioning rod 802 is fixedly connected with a baffle 803, one side of the baffle 803 is installed with a spring 804, and the inner wall of the spring 804 is sleeved with a fixing rod 805, and one end of the fixing rod 805 is fixedly connected with a connecting rod 806.

[0029] Through the above technical scheme, by starting the motor 301, the screw rod 302 can be driven to rotate and the moving block 303 can be driven to move at the same time. Since the threads on both sides of the screw rod 302 rotate in opposite directions, the two moving blocks 303 can move relative to each other, and then the distance between the limit plates 304 can be adjusted according to the different widths of the carrier tape. By manually rotating the screw rod 305, the lifting plate 307 on one side of the lifting block 306 can be lifted up and down, so that the lifting plate 307 can be moved downward to the top of the carrier tape for spatial limitation, which is convenient for adjustment according to the thickness of different carrier tapes, thereby improving the practicability of the cutting device.

[0030] Specifically, a conveying mechanism 4 is provided on the top of the workbench 1 .

[0031] Through the above technical solution, it is convenient to start the conveying mechanism 4 to make the turntable rotate. The rotation of the turntable can drive the carrier belt to move through the friction force, thereby achieving the effect of moving the carrier belt.

[0032] Specifically, the motor 301 forms a moving structure through the screw rod 302 and the moving block 303 , and the threads on both sides of the screw rod 302 have opposite rotation directions, and the number of the moving blocks 303 is two.

[0033] Through the above technical solution, it is convenient to start the motor 301 to drive the screw rod 302 to rotate and drive the moving block 303 to move at the same time, because the threads on both sides of the screw rod 302 rotate in opposite directions, and the two moving blocks 303 are symmetrically arranged on both sides of the screw rod 302, so that the two moving blocks 303 can move relative to each other, achieving the effect of the two moving blocks 303 moving in opposite directions.

[0034] Specifically, the moving block 303 forms a rotating structure with the limiting plate 304 and the screw rod 305 , and one end of the screw rod 305 extends into the limiting plate 304 to rotate.

[0035] Through the above technical solution, the moving block 303 can drive the limiting plate 304 to move synchronously during the movement, so that the limiting plate 304 can be adjusted in position according to carriers of different widths, thereby achieving the effect of adjusting the distance between the two limiting plates 304.

[0036] Specifically, the screw rod 305 forms a lifting structure through the lifting block 306 and the lifting plate 307 , and the external thread of the screw rod 305 matches the internal thread of the lifting block 306 .

[0037] Through the above technical solution, it is convenient to manually rotate the screw rod 305 to make the lifting block 306 move up and down. When the lifting block 306 is lifted or lowered, it can drive the lifting plate 307 to move up and down. The lifting plate 307 can adjust the height of the space in the carrier moving channel to prevent the carrier from warping during the movement, thereby stabilizing the movement of the carrier.

[0038] Specifically, the cutter 7 forms a snap-fit ​​structure with the positioning rod 802 through the positioning groove 801 , and the shape and size of the positioning groove 801 match the shape and size of the positioning rod 802 .

[0039] Through the above technical solution, the installation between the cutter 7 and the connecting block 6 is facilitated by extending the positioning rod 802 into the positioning groove 801 to fix the top of the cutter 7. The positioning rod 802 can clamp the cutter 7 and the connecting block 6 to fix the cutter 7, and the positioning rod 802 has an inward force under the action of the spring 804.

[0040] Specifically, the positioning rod 802 forms a fixed structure with the baffle 803 and the fixing rod 805, and the fixing rod 805 is arranged between the baffle 803 and the connecting rod 806. The connecting block 6 forms an elastic structure with the baffle 803 through the spring 804, and one end of the fixing rod 805 passes through the spring 804 and is connected to the baffle 803.

[0041] Through the above technical solution, it is convenient to pull the connecting rod 806 by hand to drive the baffle 803 at one end of the fixed rod 805 to move outward. During the outward movement of the baffle 803, the positioning rod 802 will move outward, so that the positioning rod 802 will be disengaged from the positioning groove 801, thereby releasing the limit fixation of the cutter 7, and then the cutter 7 can be disassembled and replaced.

[0042] Working principle: When using the cutting device of the carrier tape, first, when adjusting the distance between the two limit plates 304, start the motor 301 first, the motor 301 drives the screw rod 302 to rotate, the screw rod 302 drives the moving block 303 to move, because the threads on both sides of the screw rod 302 rotate in opposite directions, and then the two moving blocks 303 drive the two limit plates 304 to move inward, and adjust according to the width of the carrier tape, and then turn the screw rod 305 by hand, the screw rod 305 drives the lifting plate 307 on one side of the lifting block 306 to move up and down, the lifting plate 307 can adjust the height of the space in the carrier tape moving channel, and has a stabilizing effect on the movement of the carrier tape. When replacing the cutter 7, It is only necessary to pull the connecting rods 806 on both sides of the connecting block 6 outward, and the connecting rods 806 can drive the baffle 803 at one end of the fixing rod 805 to move outward. During the outward movement of the baffle 803, the positioning rod 802 will move outward, so that the positioning rod 802 disengages from the positioning groove 801, and the limit fixation of the cutter 7 is released. Then the cutter 7 is pulled out, and the top of the new cutter 7 is inserted into the inner wall of the connecting block 6. Then the connecting rod 806 is loosened, and the baffle 803 moves inward under the action of the spring 804, so that the positioning rod 802 is inserted into the positioning groove 801, and then the cutter 7 is fixed. This completes all the work. The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.
