Description

A high-precision fixed-length stripping device for flat cables

technical field

The invention belongs to the technical field of automatic processing equipment, and in particular relates to a high-precision fixed-length stripping device for flat cables.

Background technique

With the development of science and technology, the number of cables used has increased significantly, and the cable production specifications have also changed from the single one in the past to the current multiple composite cables, and cables in the form of flat and cylindrical types have emerged. The extensive use of cables not only brings us convenience, but also causes certain troubles.

In order to facilitate the use of customers, the outer sheath of both ends of the flat cable should be stripped off when the cable leaves the factory. After searching, there is no peeling device for flat cables, so at present, the outer sheath is mainly peeled manually, but there are the following outstanding problems: ① Manual peeling takes up many people, but the efficiency is low and the cost is high; ② The inner steel wire and the outer sheath of the cable are completely sintered Together, the peeling is very difficult; ③When the outer skin is manually cut, the force is difficult to control, and it is easy to cut the inner thin cable, causing potential safety hazards and waste; ④The length of the peeled outer skin is usually measured manually, resulting in an inaccurate peeling length and affecting the later stage. use.

Therefore, in view of the technical bottleneck faced by the above-mentioned flat cable stripping process, the present invention develops a high-precision fixed-length stripping device for flat cables, so as to provide technical guarantee for stripping the outer skin of the flat cable. It can greatly improve the cable processing efficiency and reduce the production cost of the enterprise. The device has broad application prospects and significant economic and social benefits.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a high-precision fixed-length stripping device for a flat ribbon cable that is safe and efficient, and provides a guarantee for improving the processing efficiency of the flat ribbon cable. On the premise of ensuring safety, the flat cable automatic peeling device realizes fast laser ring cutting, cutter moving slitting and complete peeling, and realizes precise control of peeling length and cutting depth.

In order to achieve the above object, the present invention adopts the following design scheme: a high-precision fixed-length stripping device for flat cables, as shown in FIG. 1 , comprising: a high-precision fixed-length pinch device; a wedge-shaped lateral positioning device; a laser ring-cutting device; Multi-head adaptive sliding slitting device; wedge-shaped cutting and peeling device; pneumatic clamping device. The specific invention process is as follows:

The high-precision fixed-length pinch device is characterized in that: since the outer layer of the cable is made of rubber, if the pinch device is made of plastic or metal material, the gap is too wide, and slippage will inevitably occur, resulting in unsatisfactory pinch length; If the gap is too narrow, the friction between the two will increase, and the cost will increase. In the present invention, the metal roller surface is covered with rubber material, and the rubber surface has a point-like convex structure, which can realize high-precision fixed-length pinch feeding and avoid the situation of slipping (the error of the pinch length is ±0.5 mm). In addition, the device can realize bidirectional pinch feeding, which not only completes the initial cable feeding, but also provides tension for subsequent stripping.

The wedge-shaped lateral positioning device is characterized in that: after the cable pinch length exceeds ten centimeters, it will bend and sag due to gravity, and the lateral position of the cable during the pinch feeding process is uncertain, resulting in the inability to determine the laser cutting depth. Therefore, the present invention selects a device with a wedge-shaped front and a rectangular device with the same width as the cable at the rear, which not only plays a role of lateral positioning, but also ensures that the cable can be smoothly clamped to the next working position.

The laser ring cutting device is characterized in that: the device is composed of a laser head, a hydraulic cylinder, a frame, a sliding frame and the like. The device uses a hydraulic cylinder to drive a sliding frame equipped with a laser head to slide on the frame to laterally cut the cable, and control the change of the cutting depth by controlling the energy intensity. Open the outer skin, which can greatly reduce the later peeling resistance.

The multi-cutter self-adaptive sliding slitting device is characterized in that: two or more steel wires with enhanced strength are placed in the flat cable. The resistance is very large and cannot be easily stripped, making it difficult to strip the cable as a whole. In this regard, the present invention designs a slitting device with multiple cutter heads and an adaptive cutting depth. The rear frame slides in the track, and the front slitting cutter is a cantilever structure, which can complete fixed-length cutting in the longitudinal direction, which greatly reduces the cost of cutting. The resistance when peeling the outer skin is convenient for the peeling knife to achieve the goal of peeling.

The wedge-shaped incision and peeling device is characterized in that: due to the small gap of the circumcision incision, if a bladeless peeling knife is used, the circumcision incision cannot be cut, and the peeling task cannot be achieved. The invention adopts a U-shaped peeling knife, the inner side of the peeling knife is a blade structure, and the knife is located at the same position as the laser ring cutting device in the cable movement direction. The invention not only ensures the accurate and reliable cutting position, but also makes the tool safe and reliable, and will not be easily bent or broken.

Through the invention process, a safe and efficient flat ribbon cable high-precision fixed-length stripping device is invented, which can improve the factory processing efficiency of the flat cable, save manpower input, and reduce costs.

Advantages and positive effects of the present invention:

1. The present invention can accurately control the cutting depth of the cutter, ensure that the flat cable sheath is completely cut and the inner thin lines are not scratched, and avoid the waste caused by manual cutting too deep;

2. The device of the present invention requires no manual intervention in the initial cable threading, and does not require manual assistance in the peeling process, which improves the production efficiency, saves a lot of manpower and material resources for the enterprise, and greatly reduces the production cost of the enterprise;

3. The device of the present invention is safe to use, convenient to maintain, economical and reliable, and is an efficient flat cable fixed-length stripping device.

Detailed ways

First, the flat cable relies on the power provided by the forward rotation of the fixed-length pinch device 1, and reaches the pneumatic clamping device 6 through the wedge-shaped lateral positioning device 2. When the desired stripping length is reached, the fixed-length pinch device 1 stops. At this time, the pneumatic clamping device 6 starts to clamp the cable, and then the laser cutting device 3 moves to perform a reciprocating circular cutting of the cable. After cutting, the laser cutting device 3 returns to the initial position, the pneumatic clamping device 6 is released, and the slitting device 5 When the slitting rack 7 reaches the laser ring cutting position, the slitting device 5 equipped with the upper and lower cutting tools is started to press down to complete the cutting, and returns to the original position with the slitting rack 7 to realize slitting, and then the peeling device 4 is driven by The hydraulic cylinder is driven to cut into the designated position. At this time, the fixed-length pinch device 1 is activated in the reverse direction, and the pinch cable moves in the reverse direction.
