Automatic tube opening sintering machine of multiplier tube

Abstract

The invention relates to the field of multiplier tube machining, in particular to an automatic tube opening sintering machine of a multiplier tube. The automatic tube opening sintering machine comprises a workbench, a first clamping mechanism, a second clamping mechanism, a sintering mechanism and an auxiliary mechanism. A sliding platform is arranged at the upper end of the workbench, the sintering mechanism is installed on the sliding platform, and the auxiliary mechanism is installed on the side of the sliding platform. The first clamping mechanism comprises a rotating assembly and a firstclamping assembly, the rotating assembly is installed on the sliding platform, and the first clamping assembly is fixedly connected with the rotating assembly. The second clamping mechanism comprisesa moving assembly and a second clamping assembly, and the moving assembly and the second clamping assembly are installed on the sliding platform. The sintering mechanism comprises a driving assembly and a sintering assembly. The automatic tube opening sintering machine of the multiplier tube has the beneficial effects that reliance on operator experience is reduced, and new employees can take up the post after simple training to produce productivity; consistency of product appearance and quality is improved, sintering efficiency is more than 10 times of artificial, and the yield reaches 99. 99%.

Description

technical field [0001] The invention relates to the field of multiplier tube processing, in particular to an automatic sintering machine for multiplier tube nozzles. Background technique [0002] Photomultiplier tube (Photomultiplier Tube), referred to as PMT, is a light detector with high sensitivity and fast response speed. It is widely used in photon counting, extremely weak light detection, chemiluminescence, bioluminescence research, extremely low energy ray detection, spectrophotometer, polarimeter, colorimeter, illuminance meter, dust meter, turbidimeter, optical density meter, Thermoluminescence meter, radiation calorimeter, scanning electron microscope, biochemical analyzer and other instruments and equipment. The photomultiplier tube consists of a photoemission cathode (photocathode), a focusing electrode, an electron multiplier, and an electron collector (anode). Its main working process is as follows: When light irradiates the photocathode, the photocathode exc...

Problems solved by technology

[0003] For photomultiplier tubes currently produced in China, please refer to the attached Figure 12 , including a closed vacuum vessel 7, a multiplier tube nozzle 8 and a lead pin 9. Before the closed vacuum vessel 7 and the multiplier tube nozzle 8 are sintered, the lead pin 9 becomes an irregular skewed state. During processing, the The lead pin 9 is righted, and the number of lead pins 9 is very time-consuming. Afterwards, one end of the closed vacuum vessel and the nozzle of the multiplier tube is softened by heating, and then the closed vacuum vessel and the nozzle of the multiplier tube are sintered into shape. The current multiplier tube The processing method requires workers to participate in the whole process, and it is a processing mode that is completely dependent on the experience of the operator. The experience of the personnel is solidified into process parameters and action flow sequences; excessive reliance on mature operators prevents new employees from being able to work quickly and carry out production, resulting in factory It is difficult to replace and replenish productivity, and the long-term training of new employees in the early stage also increases the cost, and the quality and appearance of the products produced by different operators will be more or less different, which also affects the quality of the products , and the production efficiency is extremely low, so it cannot be mass-produced on a large scale
