Problems solved by technology
[0005] Under normal circumstances, during the normal line drawing process of the line drawing machine, due to the thin carbon lead, it is easy to have lead breakage, lead shortage or insufficient force, which will lead to short lines, dotted lines, and missing lines on the lines drawn on the inner wall of the gas discharge tube. etc., affecting the qualified rate of finished products and the safety and reliability of operations

Embodiment Construction
[0018] In describing the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" ” and other indicated orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, with a specific configuration and operation, and therefore should not be construed as limiting the invention.
[0019] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these featu...

The invention belongs to the field of carbon lead detection of a line drawing machine, and particularly relates to a carbon line pressure detection device of a gas discharge tube line drawing machine. In the device, a line drawing pen assembly is fixed on a horizontal moving substrate; the horizontal moving substrate is connected with a sliding pair of a penholder horizontal moving bar; the horizontal moving substrate is provided with a screw; the tail end of the penholder horizontal moving bar is orderly provided with a spring and a spring fixing sleeve; a sensor mounting base is provided with a groove and an optical fiber sensor; the screw penetrates into the groove, and the optical fiber sensor is electrically connected with a PLC (Programmable Logic Controller) processor; during the normal line drawing process, the horizontal moving substrate drives the screw to move out of the groove rightwards, the optical fiber sensor receives a signal and transmits the signal to the PLC controller; when the conditions of carbon lead breakage or insufficient stress occur on carbon lead, the screw is not moved out of the groove, and the optical fiber sensor does not receive the signal, then the PLC controller sounds an alarm to stop working. The carbon lead detection device of the gas discharge tube line drawing machine, disclosed by the invention, reduces the phenomenon like lead breakage, lead lack or insufficient stress, and improves the qualified rate of finished products and the security and reliability of operation.
Description
technical field [0001] The invention relates to the field of line drawing pressure detection of a line drawing machine, in particular to a carbon and lead detection device for a line drawing machine of a gas discharge tube. Background technique [0002] The gas discharge tube is a switch-type protection device, which is often used in the first or first two stages of a multi-level protection circuit to discharge lightning transient overcurrent and limit overvoltage. It adopts a ceramic hermetic package, and the interior is composed of two or several metal electrodes with gaps, filled with inert gas (argon or neon). When the voltage applied to the two electrode terminals reaches the breakdown of the gas in the gas discharge tube, the gas discharge tube starts to discharge, changing from high impedance to low impedance, so that the surge voltage is quickly short-circuited to close to zero voltage, and the overcurrent is released. Into the ground, so as to protect the subsequen...
