Description

The utility model relates to electrical engineering and can be used in the manufacture of resistive heaters.

The utility model is intended for fastening a filament resistive material to an electrical insulating base in the manufacture of electric heating elements.

There are several ways to attach a carbon fiber to the surface of various materials. The most common is the method of mechanical twisting, compression, as well as gluing with conductive adhesives. However, it is difficult to apply these methods to the polymeric insulation material.

It is known "DEVICE FOR ELECTRICAL CONNECTION OF A RESISTIVE ROAD APPLIED TO THE BASIS OF A SCREEN PRINTING WITH ELECTRIC NETWORK" (patent No. 2220519 RU C2, IPC 7 Н05К 3/32, H01R 12 o, clamp 2000, o 2000.07, o. elastically supported by two contacts of conductive material in contact with them, each contact having a flat surface resting on the corresponding end of the resistive track and in contact with this end, and connected to a conductive tab mounted freely relative to the clamp ima.

The disadvantages of the known technical solutions include complex manufacturing technology.

The objective of this useful model is to develop a device that simplifies the manufacturing technology of a flat resistive heater with an increase in its heat-carrying ability.

The technical result is to simplify the technology and equipment and reduce the complexity of manufacturing while increasing the functional efficiency of the heater manufactured with their help.

The proposed device is the actuator of the manipulator for moving the device in space along a predetermined path.

A device for attaching a carbon filament to the surface of a polymeric material uses the properties of the polymer to soften when heated, as well as the property of an electrically conductive carbon filament to heat when an electric current passes through it.

To achieve the task and obtain the specified technical result, a device for attaching a carbon thread to the surface of a polymer material contains: a hollow carrier; the key located on it; a strap attached to a hollow carrier; bushings installed on a bar; pneumatic cylinders. A contact strip is installed on the rods of the pneumatic cylinders, on which sleeves are installed - shock absorbers. Contact groups consisting of an internal contact and an external contact soldered on the corresponding side to the printed circuit board are inserted into them. Also, scissors of the thread cutter, consisting of fixed knives of the upper and movable knives of the lower, are attached to the contact strip by screws. Knives are interconnected pivotally. The lower knife is connected to the pivot arm. A leash is mounted on the lever. The emphasis is fixed motionless on the manipulator carriage. Through the contact group, the bushing and the hollow carrier pass carbon threads.

The claimed technical solution is illustrated by drawings.

Figure 1 - device for attaching a carbon thread to the surface of a polymer material, General view.

Figure 2 is the same, a fragment with a contact group.

The device consists of: a hollow carrier 1, a key 2 located on it, mounted on carrier 1, strap 3, bushings 4, mounted on strap 3, pneumatic cylinders 5. On the rods of pneumatic cylinders 5 there is a contact strip 6 on which sleeves are installed - shock absorbers 7 .In them are inserted contact groups 8, consisting of an internal contact 9 and an external contact 10, soldered on the corresponding side to the printed circuit board 11. Also, the scissors of the thread cutter, consisting of fixed knives of the upper 13 and under izhnyh lower knife 14. Knives 13 and 14 are pivotally interconnected. The lower knives 14 are connected to the pivoting arm 15. A leash 18 is mounted on the arm. The stop 19 is fixedly mounted on the manipulator carriage. Through the contact group 8, the bushing 4 and the hollow carrier 1 are carbon threads 16. The number of contact groups 8, the bushing 4, is determined by the number of fixed threads.

The device operates as follows.

In the initial state, the contact group 8 is located at a small distance from the surface of the polymer material 17. At a given point on the surface of the polymer material, the pneumatic cylinders 5 press the contact group 8 to the surface of the material, copying its shape with sleeves - shock absorbers 7. Correspondingly, the carbon thread 16 is fixed, thereby ensuring passage electric current between the internal contact 9 and the external contact 10 of the contact group 8. During the fixation of the thread an electric current pulse is applied, the thread 16 is quickly heated tsya, as a result of thermal exposure of the polymer surface under the thread is softened. At the end of the electric pulse, the contact point between the filament and the surface quickly cools due to the low heat capacity of the heated masses of the filament and the material under it. The thread remains fixed in this place. The contact group rises and moves to a different coordinate of the surface in order to attach the carbon thread in a different coordinate. After the laying of the thread, it is trimmed. In the initial state, the knives 13 and 14 are closed. Drove 1, rotates around its axis, while the leash 18 abuts against the stop 19, reveals the scissors of the thread cutter. Then the manipulator moves along such a motion path so that the threads fall between the upper 13 and lower 14 knives of the thread cutter. When moving the contact strip 6 by pneumatic cylinders 5 to the surface of the polymer 17, the lower knives 14 are closed, abutting against the surface of the polymer, while cutting the carbon filaments. After that, the device returns to its original state and is ready to start the next cycle.
