Description
Technical field
The utility model relates to gas discharge tube process equipment field, particularly the automatic setting-out fixture of a kind of porcelain tube for gas discharge tube.
Background technology
Gas discharge tube is a kind of switching mode protection device, is usually used in the first order in multi-level protection circuit or front two-stage, works release Lightning Transient overcurrent and over-voltage effect.It adopts ceramic enclosed package, and the inner metal electrode by two or several band gap, fills and formed with inert gas (argon gas or neon).When the voltage being added to two electrode tips reaches the gas breakdown made in gas discharge tube; gas discharge tube just starts electric discharge, becomes Low ESR, surge voltage is short-circuited to rapidly close to no-voltage by high impedance; and overcurrent is released into ground, thus subsequent conditioning circuit is played a protective role.After surge voltage disappears, gas discharge tube extinguishing returns to high impedance status, waits for action next time.
The porcelain tube inwall of gas discharge tube is provided with equally distributed carbon line, because carbon is a kind of good conductor, can reduce the puncture voltage of discharge tube by drawing carbon line.For different porcelain tube specifications, the thick line of carbon line, quantity and arrangement also corresponding difference.
In existing processing technology, mainly adopt and carry out setting-out in two ways: one is manual setting-out, due to the diameter of porcelain tube less (2mm ~ 8mm), so operation easier is comparatively large, productivity ratio is low, and is difficult to the length and the uniform distribution that ensure carbon line, and precision is not high.Another kind is semi-automatic setting-out, namely clamp carbon lead by clamp to be sent to porcelain tube inwall and to carry out setting-out, due to carbon lead comparatively thin (diameter is 0.5mm ~ 0.9mm), so the length of clamp carbon used lead is all shorter, and need manually frequently to change lead, otherwise very easily there is disconnected plumbous situation.In addition, that section of carbon lead clamped due to clamp cannot use, and can only throw away, thus causes the utilization rate of carbon lead not high, adds production cost.For this reason, be badly in need of design a kind of gas discharge tube full-automatic line drawing machine, to improve the setting-out precision of porcelain tube, production efficiency and the plumbous utilance of carbon.
Drawing in carbon line process, for keeping carbon lead and the uniform force of porcelain tube wall, clamp porcelain tube need be had, and the plumbous needle point of carbon overlaps with the porcelain tube center of circle when ensureing zero-bit, otherwise, be difficult to the uniformity ensureing carbon line length and distribution, and easily cause the generation of dotted line and disconnected plumbous phenomenon.In addition, because porcelain tube specification is different, shape, the size of its correspondence are different, and the number of required setting-out and length requirement are not identical yet, thus also not identical to the requirement of fixture.Also need the porcelain tube of work at present position to deliver to finished product box after setting-out terminates, connect and treat setting-out porcelain tube from charging acquisition and clamp, carrying out the striping jobs in next cycle.For this reason, want to realize from animation line, need provide a kind of and be applicable to the fixture of plurality of specifications porcelain tube from animation line operation, complete automatic material taking, setting-out and discharging operation with auxiliary setting-out mechanism.
