Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a solder paste viscosity testing device, which aims to improve the problem in the prior art that if automated measurement cannot be achieved, excessive human intervention will lead to reduced measurement accuracy and affect the measurement results.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a solder paste viscosity testing device, comprising a pole, a connecting block slidably connected to the bottom of the pole, a support plate fixedly connected to the front side of the outer wall of the connecting block, a hollow shell fixedly connected to the front side of the support plate, a sliding column slidably connected inside the hollow shell, a weight fixedly connected to the bottom of the outer wall of the sliding column, a collar slidably connected to the top of the outer wall of the pole, a fixing plate fixedly connected to the front side of the collar, a plurality of sliding grooves opened on the front side of the fixing plate, a viscometer slidably connected to the inner wall of the sliding grooves, a measuring port fixedly connected to the bottom of the viscometer, and a lifting mechanism provided at the bottom of the pole for adjusting the height of the device.

[0008] The lifting mechanism includes a support foot, the front side of the outer wall of the support foot is fixedly connected to the outer wall of the connecting block, the bottom of the support foot is threadedly connected to a threaded rod, the bottom of the outer wall of the threaded rod is fixedly connected to a fixed plate, the outer wall of the fixed plate is fixedly connected to multiple protrusions, the bottom of the threaded rod is fixedly connected to a rotating ball, and the bottom of the outer wall of the rotating ball is rotatably connected to a support block.
[0009] The above technical solution—the threaded connection between the support foot and the threaded rod—not only ensures the stability of the entire structure but also demonstrates extremely high reliability in practical applications. The protrusion cleverly increases the friction with the ground, thus providing additional stability support in various working environments. The threaded rod is fixedly connected to a swivel ball, further enhancing the support effect and allowing the support system to adapt more flexibly to different ground inclinations, thereby providing flexible and stable support. The swivel ball is rotatably connected to the support block, enabling the entire support system to adapt more flexibly to various terrains, ensuring the stability and adaptability of the support.
[0010] As a further description of the above technical solution:

[0017] Rubber blocks are fixedly connected to the top left and right sides of the outer wall of the viscometer, and sponge blocks are fixedly connected to the bottom left and right sides of the outer wall of the viscometer.
[0018] Through the above technical solutions: the viscometer is not only related to the accuracy of the measurement, but also affects the convenience of operation. The rubber block not only stabilizes the viscometer, but also effectively absorbs vibration and protects the instrument from external impacts. The sponge block not only provides additional support for the equipment, but also prevents the instrument from being scratched or damaged when moving on hard surfaces.
[0019] As a further description of the above technical solution:
[0020] The outer wall of the collar is threadedly connected to a threaded rod two, and a throttle is fixedly connected to the right side of the threaded rod two.
[0021] The above technical solution allows the operator to easily make manual adjustments using the throttle.
[0022] As a further description of the above technical solution:
[0023] The outer wall of the threaded rod is threaded to the inner wall of the upright, and the rear side of the viscometer is slidably connected to the front side of the fixing plate.

[0027] Through the above technical solution, the gasket can not only effectively prevent the screw from loosening during use, but also absorb vibrations caused by the working environment, thereby ensuring the stability of the connection.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, solder paste is injected into the measuring port, and the viscometer is moved to slide on the inner wall of the trough. The position is adjusted to insert different sliding columns. The solder paste makes the sliding columns adhere to the measuring port. After the measuring port is raised, the weight makes the sliding columns descend. By measuring the descent speed, the viscometer calculates the viscosity of the solder paste, thus realizing accurate measurement of the solder paste viscosity, reducing manual intervention, improving the accuracy of measurement, and providing a guarantee for subsequent use.
[0030] 2. In this utility model, if the platform has a slope, when the fixed plate is rotated, the protrusion increases the friction force, which facilitates operation. The fixed plate drives the threaded rod and the rotating ball to rotate. The rotation of the threaded rod causes the support foot to rotate outward, thereby moving the support foot upward, realizing the adjustment of the equipment height, preventing the measurement result error due to the slope, and improving the measurement accuracy and the practicality of the equipment.

[0042] Specifically, the support foot 201 is threadedly connected to the threaded rod 202, which not only ensures the stability of the entire structure but also demonstrates extremely high reliability in practical applications.

[0047] Working principle: The solder paste to be measured is injected into the measuring port 12. Then, by moving the viscometer 11, the viscometer 11 will slide on the inner wall of the slide groove 10, thereby adjusting the position of the viscometer 11 so that the measuring port 12 is inserted into the outer wall of different sliding columns 6. The solder paste inside the measuring port 12 will stick the sliding column 6 to the measuring port 12. Then, the measuring port 12 is moved upward. Different weights 7 are fixed on the outer walls of different sliding columns 6. After the measuring port 12 is pulled up, the sliding column 6 will move downward under the gravity of the weights 7. The viscometer 11 can calculate the viscosity of the solder paste by measuring the speed at which the sliding column 6 falls. This achieves accurate measurement of solder paste viscosity, reduces manual intervention, improves measurement accuracy, and provides a guarantee for subsequent use.
[0048] If the platform has a certain slope, rotating the fixed disk 203 will increase the friction between the finger and the fixed disk 203, making it easier for the user to rotate. The fixed disk 203 will drive the threaded rod 202 and the rotating ball 205 to rotate together. During the rotation, the threaded rod 202 will rotate out from the inside of the support foot 201, which will move the support foot 201 upward, thereby adjusting the height of the equipment. This prevents errors in the measurement results due to the slope, improves the accuracy of the measurement and the practicality of the equipment.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
