Description

A conductive fabric precision cutting device

Technical Field

The present invention relates to the technical field of cutting devices, and in particular to a conductive cloth precision cutting device.

Background Art

Conductive cloth is a fiber cloth that has conductive function after being electroplated with metal. It is installed on gloves to assist people in touching the capacitive screen. In order to process the conductive cloth into a specified shape, a cutting device is required.

The existing cutting device has a large positioning deviation for the material tray, and the center line of the material tray after installation has a large deviation from the center line of the die-cutting knife, which requires that some margin be left on the side of the conductive cloth during die-cutting processing, resulting in low utilization rate of the conductive cloth raw materials and increased production costs. The existing cutting device usually directly pulls the waste material off the substrate after cutting is completed, but a partial connection is inevitably left between the finished product and the waste material. Pulling the waste material when the finished product is not fixed can easily separate the finished product from the substrate along with the waste material, resulting in a waste of production raw materials and further reducing production efficiency. In addition, the existing cutting device is usually provided with a position detection device, and during the continuous processing of the conductive cloth, the error accumulation is too large, which may cause the conductive cloth to deviate from the original moving trajectory, making it impossible for the die cutter to accurately complete the cutting process. The existing cutting device is usually not provided with an ejection mechanism, and after the die cutter completes the processing of the conductive cloth, the finished product may separate from the substrate along with the die cutter, causing the die cutter to be blocked, affecting subsequent processing. In view of the above problems, it is necessary to improve the existing equipment.

Summary of the invention

The object of the present invention is to provide a conductive cloth precision cutting device to solve the problem that the existing cutting device mentioned in the above background technology has a large positioning deviation of the material tray, and the center line of the material tray after installation has a large deviation from the center line of the die-cutting knife, so that when performing the die-cutting process, it is necessary to leave some margin on the side of the conductive cloth, resulting in low utilization rate of the conductive cloth raw materials and increased production costs. The existing cutting device usually directly pulls the waste material off the substrate after completing the cutting, but a partial connection is inevitably left between the finished product and the waste material. When the waste material is pulled when the finished product is not fixed, it is easy to separate the finished product from the substrate together with the waste material, resulting in a waste of production raw materials and further reducing production efficiency. In addition, the existing cutting device is usually provided with a position detection device, and during the continuous processing of the conductive cloth, the error accumulation is too large, which may cause the conductive cloth to deviate from the original moving trajectory, so that the die cutter cannot accurately complete the cutting process. The existing cutting device is usually not provided with an ejection mechanism, and after the die cutter completes the processing of the conductive cloth, the finished product may be separated from the substrate along with the die cutter, resulting in blockage of the die cutter and affecting subsequent processing.

Working principle: When using the conductive cloth precision cutting device, the model of the Hall current sensor 84 is AH3144EUA, and the model of the signal processor 85 is TMS320F28016PZA. First, place the unwinding disk 25 between the two first slides 23, so that the two ends of the unwinding disk 25 are respectively arranged on a first rotating member 24, connect the external power supply, start the first drive motor 22, the first drive motor 22 drives the first lead screw 21 to rotate, the first lead screw 21 pushes the two first slides 23 to move toward each other along the first slide groove 20, so that the two first rotating members 24 clamp the unwinding disk 25, and at the same time, the unwinding disk 25 is meshed and connected with the first rotating member 24 through the end face teeth 26, and the winding disk 39 is placed between the second slide 33 and the third slide 34, and the second drive motor 32 is started.

The first servo motor 35 is started, and the first servo motor 35 pulls the take-up reel 39 to rotate through the pulley 38, and the take-up reel 39 rewinds the conductive cloth, so that the conductive cloth moves to the right. The second servo motor 44 is started, and the second servo motor 44 drives the eccentric wheel 43 to rotate. The eccentric wheel 43 pulls the slide plate 41 to reciprocate up and down along the third slide groove 40 through the connecting rod 42.

When the conductive cloth moves, the positive pole of the battery 83 sends electricity to the discharge contact 82. Once the moving trajectory of the conductive cloth deviates, the discharge contact 82 and the power receiving contact 81 contact the conductive cloth or the same finished product at the same time. At this time, the positive pole of the battery 83, the discharge contact 82, the conductive cloth, the power receiving contact 81, the Hall current sensor 84 and the negative pole of the battery 83 form a loop, which is convenient for the Hall current sensor 84 in the loop to detect the current signal, which is then transmitted to the signal processor 85.
