Description

Flat cable high accuracy fixed length device of skinning

Technical Field

The invention belongs to the technical field of automatic processing equipment, and particularly relates to a high-precision fixed-length peeling device for a flat cable.

Background

With the development of science and technology, the number of cables used is remarkably increased, and the manufacturing specifications of the cables are generated from the conventional single cable which tends to be in the form of a plurality of cables, such as a flat cable, a cylindrical cable and the like. The use of a large number of cables brings convenience to people and causes certain trouble.

In order to facilitate the use of customers, the outer skins at the two ends of the flat cable need to be stripped when the cable leaves a factory. After retrieval, no peeling device for flat cables exists, so that the manual peeling is mainly adopted at present, but the following outstanding problems exist: firstly, manual peeling occupies more personnel, but the efficiency is low and the cost is high; secondly, the steel wire and the sheath in the cable are completely sintered together, so that the peeling difficulty is high; the strength is difficult to control when the sheath is manually cut, and the thin cable inside the sheath is easy to cut, so that potential safety hazards and waste are caused; the length of the peeled skin is usually measured manually, so that the peeling length is inaccurate, and the later use is influenced.

Therefore, the invention develops a high-precision fixed-length peeling device for the flat cable aiming at the technical bottleneck faced by the peeling process of the flat cable, and provides technical guarantee for peeling the outer skin of the flat cable. The device can greatly improve the cable processing efficiency and reduce the production cost of enterprises, and has wide application prospect and great economic and social benefits.

Disclosure of Invention

The invention aims to provide a safe and efficient high-precision fixed-length peeling device for a flat ribbon cable, which guarantees improvement of the processing efficiency of the flat cable. The automatic flat cable peeling device realizes rapid laser circular cutting, cutter moving longitudinal cutting and peeling completion on the premise of ensuring safety, and realizes accurate control of peeling length and cutting depth.

In order to achieve the purpose, the invention adopts the following design scheme: a high-precision fixed-length peeling device for flat cables, as shown in fig. 1, comprising: a high-precision fixed-length clamping and conveying device; a wedge-shaped transverse positioning device; a laser annular ring cutting device; a multi-cutter head self-adaptive sliding longitudinal cutting device; a wedge cut into the peeling device; a pneumatic clamping device. The specific invention process is as follows:

high accuracy fixed length presss from both sides send device, its characterized in that: because the outer layer of the cable is made of rubber, if the clamping and conveying device is made of plastic or metal materials, the clamping gap is too wide, so that slipping is inevitable, and the clamping and conveying length is not satisfactory; and the crack is too narrow, the friction between the two will be increased, and the cost will be increased. According to the invention, the rubber material is covered on the surface of the metal roller, and the rubber surface is of a punctiform convex structure, so that high-precision fixed-length clamping and conveying can be realized, and the condition of slipping (the clamping and conveying length error is +/-0.5 mm) is avoided. In addition, the device can realize two-way pinch, not only accomplish initial cable feeding, also provide tension for follow-up skinning.

The wedge-shaped transverse positioning device is characterized in that: after the length of the cable is over ten centimeters in clamping and conveying, bending and sagging can be caused due to gravity, and meanwhile, the transverse position of the cable is uncertain in the clamping and conveying process, so that the laser cutting depth cannot be determined. Therefore, the device with the wedge-shaped front part and the rectangular rear part with the same width as the cable is selected, not only is the device capable of achieving the transverse positioning effect, but also the cable can be guaranteed to be smoothly clamped and conveyed to the next working position.

The laser circular cutting device is characterized in that: the device consists of a laser head, a hydraulic cylinder, a rack, a sliding rack and the like. The device drives the carriage that is equipped with the laser head through the pneumatic cylinder and slides on the frame and carry out horizontal circular cutting to the cable, comes the control to cut into the change of degree of depth through control energy intensity, and the sheath of cutting as deep as possible under the prerequisite of not damaging inside thin cable can reduce later stage resistance of skinning by a wide margin.

The multi-cutter-head self-adaptive sliding longitudinal cutting device is characterized in that: two or more steel wires with enhanced strength are placed in the flat cable, and the steel wires and the sheath are completely sintered together in the sintering process of the sheath of the cable, so that the resistance is very large and cannot be easily stripped in the later peeling process, and the whole peeling of the cable is difficult. Therefore, the longitudinal cutting device with the multiple tool bits and the self-adaptive cutting depth is designed, the rear end rack slides in the track, the front end longitudinal cutting tool is of a cantilever structure, fixed-length cutting can be completed longitudinally, resistance in peeling is greatly reduced, and peeling can be conveniently achieved by the peeling tool.

The wedge-shaped cutting-in peeling device is characterized in that: because the annular cutting cut gap is small, if a non-edge peeling knife is adopted, the annular cutting cut cannot be cut, and the peeling task cannot be realized. The invention adopts a U-shaped skinning knife, the inner side of the skinning knife is of a knife edge structure, and the knife is positioned at the same position with the laser circular cutting device in the cable moving direction. The invention not only ensures the accurate and reliable cutting position, but also ensures the safety and reliability of the cutter, and cannot be easily bent or broken.

Through the invention process, the high-precision fixed-length peeling device for the flat ribbon cable is invented, and the purposes of improving the factory processing efficiency of the flat cable, saving the labor input and reducing the cost can be achieved.

The invention has the advantages and positive effects that:

1. the invention can accurately control the cutting depth of the cutter, ensures that the outer skin of the flat cable is completely cut and the thin line inside the flat cable is not scratched, and avoids waste caused by manual cutting too deep;

2. the device needs manual intervention in the first cable threading process, manual assistance is not needed in the peeling process, the production efficiency is improved, a large amount of manpower and material resources are saved for enterprises, and the production cost of the enterprises is greatly reduced;

3. the device is safe to use, convenient to maintain, economical and reliable, and is an efficient flat cable fixed-length peeling device.
