Description

Technical Field

[0001] The utility model relates to the technical field of solder paste viscosity detection, in particular to a solder paste viscosity detection device. Background Art

[0002] Solder paste is mainly made of solder powder, flux and other surfactants, thixotropic agents, etc. Solder paste is a welding material widely used in electronic manufacturing, mainly used for welding electronic components such as surface resistors, capacitors, and ICs on PCBs (printed circuit boards) in the SMT (surface mount technology) industry.

[0003] The viscosity of solder paste plays a decisive role in the quality of welding process, so it is necessary to use a solder paste viscosity detection device to detect its viscosity. At present, when detecting the viscosity of solder paste, the detection structure is in contact with the solder paste, and the sensor pulls the detection structure to obtain the viscosity data of the solder paste. However, the detection structure area of ​​the solder paste viscosity detection device is fixed and the contact area with the solder paste cannot be changed, so the accuracy of the solder paste viscosity detection data cannot be guaranteed.

During testing, the threaded rod is rotated by the first driving device, and the test plate located above the test cup can be lowered into the test cup with the cooperation of the movable block so as to contact the solder paste. Then the test plate is raised, and the tension applied by the solder paste to the test plate can be detected by the pressure sensor, so as to obtain viscosity data. After one test, the rotating shaft is rotated by the second driving device so that other test plates of different sizes are located above the test cup, and then the test is performed again. The above operation is repeated, and viscosity test can be performed using test plates of different sizes.

[0008] Preferably, a supporting leg is installed at the lower end of the detection platform, and there are four supporting legs in total, and the four supporting legs are distributed in an array with respect to the detection platform.
