Description

Technical Field

[0001] The utility model relates to a field, and in particular to a cutting device for producing flexible flat cables. Background Art

[0002] The cutting device used in the production of flexible flat cables is mainly used for precise cutting and cutting of flexible circuit connectors, especially in the manufacture of flexible flat cables (FFC) or flexible printed circuits (FPC). The device uses precise cutting tools or cutting mechanisms to cut flexible substrates and metal conductive materials (such as copper foil) according to the required size and shape to meet the design requirements of different electronic products. The accuracy and stability of the cutting device have a direct impact on the quality and performance of the product, ensuring the dimensional accuracy and edge flatness of the connector, and avoiding problems such as circuit disconnection or connection failure caused by inaccurate cutting. Therefore, the cutting device plays a key role in the production of flexible flat cables, not only improving production efficiency, but also ensuring the reliability and stability of the product. It is an indispensable part of the modern electronic manufacturing industry.

[0003] The shortcomings of the existing device are that during use, the entire device lacks accurate length measurement and adjustment components. Usually, personnel use a ruler to measure and mark the flexible cable first, and then cut it. In this way, there must be a certain difference between the length value after measurement and cutting and the accurate value, which leads to low cutting accuracy. During use, the entire device requires at least a pair of motors or cylinders to drive the cutting knives on both sides to cut the flexible cable. Therefore, the internal structure of the cutting equipment will be complicated, increasing the difficulty of maintenance. At the same time, more motors and cylinders will also increase the cost of the equipment. Utility Model Content

[0018] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0019] See also Figure 1-3 According to an embodiment of the utility model, a cutting device for the production of flexible flat cables includes a base 1, a threaded hole 2 is opened on one side of the base 1, a movable distance adjustment mechanism 3 is installed on the other side of the base 1, a driving box 4 is installed on the movable distance adjustment mechanism 3, and a cutting mechanism 5 is installed in the driving box 4. The movable distance adjustment mechanism 3 includes a slide groove 6 opened in the side wall of the base 1, a motor 7 is fixedly installed at the end of the base 1, and a bidirectional screw rod 8 is installed at the output end of the motor 7. The ends of the bidirectional screw rod 8 pass through the side walls of the two ends of the slide groove 6 and are rotatably connected through bearings. Both ends of the bidirectional screw rod 8 are threadedly connected with moving blocks 9, and the moving blocks 9 are slidably connected to the slide groove 6.

[0020] Among them, the threaded hole 2 is used to facilitate the installation of the equipment on the conveying device of the flexible cable. The length to be cut is adjusted by moving the distance adjustment mechanism 3, and then the cutting mechanism 5 performs the cutting operation. The motor 7 drives the bidirectional screw 8 to rotate, and the bidirectional screw 8 drives a pair of moving blocks 9 to move toward or away from each other. The function of the slide groove 6 is to limit the moving block 9.

[0021] In this embodiment, the moving block 9 is fixedly connected to the driving box 4, and a cylinder 10 is fixedly installed on the outside of the driving box 4. A piston rod 11 is installed on the output end of the cylinder 10. The end of the piston rod 11 is rotatably connected to one end of a first connecting member 12 through a rotating member. The other end of the first connecting member 12 is rotatably connected to one end of a connecting rod 13 through a rotating member. The other end of the connecting rod 13 is vertically fixedly connected to a swing plate 14.

[0022] The cylinder 10 drives the piston rod 11 to extend and retract, and the piston rod 11 drives the end of the connecting rod 13 to swing up and down through the first connecting member 12, and the connecting rod 13 drives the upper and lower ends of the swing plate 14 to swing around its center.

[0023] In this embodiment, the upper and lower ends of the swing plate 14 are rotatably connected to one end of the second connecting member 15 through a rotating member, and the other end of the second connecting member 15 is rotatably connected to the fixed block 16 through a rotating member. The fixed block 16 is fixedly installed in the middle of the side of the fixed plate 17. A rotating shaft 18 passes through and is fixedly installed in the middle of the swing plate 14. The rotating shaft 18 is rotatably installed on the side wall of the drive box 4 through a bearing.

[0024] The swing plate 14 drives the fixed block 16 to move through the second connecting member 15 , and the fixed block 16 drives the fixed plate 17 to move.

[0025] In this embodiment, slide cylinders 19 are penetrated and installed at the four corners of both ends of the driving box 4, and slide rods 20 are slidably connected in the slide cylinders 19. The slide rods 20 penetrate the two ends of the fixed plate 17 and are fixedly connected. A first cutting knife 21 is fixedly installed at the end of a pair of slide rods 20 above the driving box 4, and a second cutting knife 22 is fixedly installed at the end of a pair of slide rods 20 below the driving box 4.

[0026] Among them, the slide cylinder 19 plays a role in limiting the slide rod 20 and making its sliding more stable. The fixed plate 17 drives the slide rod 20 to move. Since the swinging directions of the upper and lower ends of the swing plate 14 are always opposite, the slide rod 20 drives the first cutting knife 21 and the second cutting knife 22 to move toward or away from each other to achieve continuous cutting operation.

[0027] In specific application, first, the device is installed on the conveying mechanism of the soft cable through the threaded hole 2. According to the required length, the motor 7 is started to drive the bidirectional screw rod 8 to rotate, and the bidirectional screw rod 8 drives a pair of movable blocks 9 to move toward or away from each other. The movable block 9 drives the drive box 4 to move, thereby changing the spacing of the adjusting cutting mechanism 5, and then realizing the length adjustment. Then, the cylinder 10 is started to drive the piston rod 11 to extend and retract. The piston rod 11 drives the end of the connecting rod 13 to swing up and down through the first connecting member 12, and the connecting rod 13 will drive the upper and lower ends of the swing plate 14 to swing around its center. The swing plate 14 drives the fixed block 16 to move through the second connecting member 15, and the fixed block 16 drives the fixed plate 17 to move. The fixed plate 17 drives the slide bar 20 to move. Since the swinging directions of the upper and lower ends of the swing plate 14 are always opposite, the slide bar 20 drives the first cutting knife 21 and the second cutting knife 22 to move toward or away from each other, thereby realizing continuous cutting operation.
