Description

Technical Field

[0001] This utility model relates to the field of carrier tape trimming technology, and in particular to a trimming device for manufacturing carrier tapes for electronic components. Background Technology

[0002] In the manufacturing process of electronic component carrier tape, the edge trimming device is a key piece of equipment. It is mainly used to process the edges of the carrier tape. Electronic component carrier tape usually has specific dimensional requirements such as width and thickness. The edge trimming device can remove edge burrs and excess material that may occur during the production process, so that the width and other dimensions of the carrier tape meet the design standards and ensure the consistency of different batches of products. For example, in the production of roll carrier tape, the edge trimming device can accurately control the edge position and avoid deviations in subsequent processing due to irregular edges, ensuring the compatibility of the carrier tape with automated equipment.

[0003] However, existing technologies, such as Chinese Publication No. CN222494429U, "A Cutting Device for Manufacturing Carrier Tape for Electronic Components," relate to the field of carrier tape cutting and disclose a cutting device for carrier tape used in 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. A spring on the outer ring of the telescopic rod presses and limits the carrier tape. The position of the adjusting plate is adjusted using the adjusting block within the fixed frame according to the cutting length, and the rotating handle drives the pressure roller on the rotating shaft to rotate, causing the carrier tape to automatically move to contact the adjusting plate, thus completing the cutting process in conjunction with the cutting mechanism.

[0004] However, this device does not have a structure for simultaneously cutting and flattening both sides, so it cannot process both sides of the carrier belt at the same time. It cannot solve the limitations of single-sided cutting, cannot improve the processing quality from multiple dimensions such as accuracy, efficiency, and stability, cannot remove excess material on both sides at the same time through a symmetrical tool structure, and cannot ensure that the width of the carrier belt remains accurate after processing. This leads to problems such as left and right edge offset and uneven width that may occur with single-sided cutting. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, such as the inability to simultaneously process both sides of the bearing belt, the inability to solve the limitations of single-sided cutting, the inability to improve processing quality from multiple dimensions such as accuracy, efficiency, and stability, the inability to simultaneously remove excess material on both sides through symmetrical tool structures, and the inability to ensure that the width of the bearing belt remains accurate after processing, which may lead to left and right edge offset and uneven width due to single-sided cutting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cutting device for manufacturing electronic component carrier tape, comprising a double-groove worktable, a protective shell fixedly connected to the bottom of the double-groove worktable, a main rod rotatably connected to the bottom of the double-groove worktable, the outer surface of the main rod rotatably connected to the bottom of the protective shell, and a synchronization component provided at the bottom of the main rod;

[0007] The synchronization component includes a synchronization rod, the top of which is fixedly connected to the bottom of the main rod. Both ends of the synchronization rod are rotatably connected to connecting rods. The end of the connecting rod away from the synchronization rod is rotatably connected to a follower rod. The top of the follower rod is fixedly connected to the main housing. The bottom of the main housing is fixedly connected to two limiting sleeves. Multiple limiting rods are movably embedded in the inner surface of the limiting sleeves. Both ends of the multiple limiting rods are fixedly connected to the inside of the double-slot worktable. The other end of the connecting rod pushes the main housing through the follower rod, causing the main housing and the limiting sleeves to move closer or further apart along the axial direction of the limiting rods.

[0008] In a preferred embodiment, a worm gear is fixedly sleeved on the outer surface of the main rod, and a worm is meshed with the outer surface of the worm gear. The outer surface of the worm is rotatably connected to the inside of the protective shell and extends out one end. Under the meshing action of the worm and the worm gear, the main rod will be driven to rotate at the bottom of the double-groove worktable.

[0009] In a preferred embodiment, a first mounting plate is fixedly connected to one side of the protective shell, and a first motor is fixedly embedded on the inner surface of the first mounting plate. The output end of the first motor is fixedly connected to one end of the worm gear extension, and the first motor is fixed to one side of the protective shell through the first mounting plate.

[0010] In a preferred embodiment, a threaded rod is rotatably connected inside the main housing and extends out one end. An internal threaded block is threadedly connected to the outer surface of the threaded rod. The outer surface of the internal threaded block is movably embedded inside the main housing. A cutting blade is fixedly connected to the top of the internal threaded block. The material cut off is a relatively continuous item, so it will not affect the meshing of the threaded rod and the internal threaded block.

[0011] In a preferred embodiment, a mounting sleeve is fixedly connected to one side of the main housing, and a second motor is fixedly embedded on the inner surface of the mounting sleeve. The output end of the second motor is fixedly connected to one end of the threaded rod. When the second motor is energized, it will drive the threaded rod to rotate inside the main housing.

[0012] In a preferred embodiment, a pressure plate is fixedly connected to the top of the double-groove worktable, and multiple support legs are fixedly connected to the bottom of the double-groove worktable. The support legs at the bottom of the device serve to fix and support the entire device.

[0013] In a preferred embodiment, the top of the double-slot workbench is fixedly connected to two support plates, and the top of the two support plates is fixedly connected to a top plate, which is fixed above the double-slot workbench by the support plates.

[0014] In a preferred embodiment, two second mounting plates are fixedly connected to the top of the top plate, and cylinders are fixedly connected to the inner sides of the two second mounting plates. A pressure plate is fixedly connected to the output end of the cylinder. After the cylinder performs its work, it pushes the pressure plate down to initially fix the bearing belt.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] This utility model features a device with a structure that simultaneously cuts and flattens both sides, enabling synchronous processing of both edges of the carrier belt. This overcomes the limitations of single-sided cutting and improves processing quality in multiple dimensions, including precision, efficiency, and stability. The symmetrical tool structure allows for the simultaneous removal of excess material from both sides, ensuring that the width of the carrier belt remains accurate after processing and avoiding issues such as left and right edge offset and uneven width that may result from single-sided cutting.

[0028] like Figures 1 to 5 As shown, a first mounting plate 12 is fixedly connected to one side of the protective shell 2. A first motor 13 is fixedly embedded on the inner surface of the first mounting plate 12. The output end of the first motor 13 is fixedly connected to one end of the worm gear 11.

[0029] like Figures 1 to 5 As shown, a threaded rod 14 is rotatably connected inside the main housing 7 and extends out one end. An internal threaded block 15 is threadedly connected to the outer surface of the threaded rod 14. The outer surface of the internal threaded block 15 is movably embedded inside the main housing 7. A cutting blade 16 is fixedly connected to the top of the internal threaded block 15. Rotating the thread will drive the internal threaded block 15, and the cutting blade 16, which moves with the internal threaded block 15, will cut and trim the two sides of the carrying belt.
