Description

Steel mesh test experiment table Technical Field The utility model relates to the field of test experiment tables, in particular to a steel mesh test experiment table. Background The steel mesh is a tool used in the manufacturing process of a Printed Circuit Board (PCB), is mainly used for manufacturing circuit patterns on a substrate, is a thin sheet made of metal materials (usually stainless steel), has accurate hole patterns on the surface, is precisely designed and used for coating soldering paste or other materials on the circuit board, can ensure that each soldering point can obtain proper amount of soldering paste by using the steel mesh, thereby improving the welding quality of the circuit board, avoiding manual operation errors by using the consistency of the steel mesh, ensuring the uniformity of the solder paste quantity of each PCB, reducing quality fluctuation after reflow soldering, and is particularly important for automotive electronics and medical equipment. The steel mesh is often required to be subjected to tension detection in practical application, the steel mesh tension detection is generally carried out by testing 5 points, one point in the middle, 4 points are selected by four weeks of the steel mesh, and the tension of any point of the 5 points is less than 38N to be unqualified, however, the existing testing device can only carry out limit fixing and tension testing on the steel mesh of a specific model, cannot measure the steel mesh of different sizes, and is difficult to meet the practical use requirement. Accordingly, a steel mesh test bench is provided by those skilled in the art to solve the problems set forth in the background art. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a steel mesh test experiment table, wherein a moving block can be moved when a threaded plate moves, and an air bag can be used for extruding two sides of a steel mesh when the moving block moves to one side of the steel mesh, so that the steel mesh can be kept stable at the upper end of a main body. In order to achieve the aim, the steel mesh test experiment table comprises a main body, wherein a moving module is fixedly arranged on the inner top surface of the main body, sliding grooves are formed in the front and rear parts of the inner top surface of the main body, moving blocks are slidably arranged on two sides of the upper end surface of the main body, and air bags are fixedly arranged on the opposite sides of the two moving blocks; The movable module comprises a placement box, a supporting plate is fixedly arranged on the bottom surface in the placement box, a rotary motor is fixedly arranged on the upper end surface of the supporting plate, a protection box is fixedly arranged on the rear end surface of the placement box, and two first chain wheels are fixedly arranged on the outer surface of the output end of the rotary motor.
