Technical Field

[0001] The invention relates to the technical field of circuit board processing, and more particularly to the technical field of solder paste stirring, and in particular to a solder paste stirring machine that is conducive to full mixing. Background Art

[0002] Solder paste is generally used for welding PCB boards and electronic components. Solder paste is generally stored in a solder paste tank. Before using the solder paste, the internal substances need to be fully mixed to ensure the welding strength. The solder paste mixer can effectively mix the tin powder and flux paste evenly, and the mixing can also remove bubbles.

[0003] For example, the patent application with application number 202220159233.6 discloses a solder paste mixer, including a mixer body, a switch button is integrally formed on one side of the front of the mixer body, a control button is integrally formed on the front of the mixer body, a timer is integrally formed on the other side of the front of the mixer body, a stabilizing component is detachably installed on the bottom end of the mixer body, a working plate is fixedly installed inside the mixer body, a bearing is inlaid and installed inside the working plate, a connecting shaft is fixedly sleeved inside the bearing, the bottom end of the connecting shaft is connected to the top of the motor, a mounting block is fixedly installed on the top of the connecting shaft, and a mixing device is fixedly installed on both sides of the top of the mounting block. In the above scheme, the solder paste mixer uses a stabilizing component to fix the mixer body, thereby ensuring the quality of the mixer body, and avoiding the problem that the solder paste mixer itself does not have a stabilizing function, so once the solder paste mixer is hit, it will cause the solder paste mixer to tilt, thereby causing damage to the device;

[0004] Another example is the patent application with application number 201520450857.3, which discloses a solder paste mixer, including a machine cover, an armrest, an observation port, a solder paste tank, a gas spring, a buffer pad, a lock, a power switch, a start button, a stop button, a timer, and a universal caster; the machine cover is arranged at the top of the mixer and is connected to the back of the mixer through a hinge; the gas spring arranged in the middle of the right side of the machine cover is connected to the right rear of the mixer; the armrest is located in the middle of the front of the machine cover; the observation port is arranged in the center of the upper end of the machine cover; the solder paste tank is arranged below the machine cover and on the rotating disk; there are two solder paste tanks, which are symmetrically arranged on the rotating disk; the buffer pad is arranged around the upper end of the mixer; the lock is arranged at the two ends of the front of the mixer; the power switch, the start button, the stop button, and the timer are arranged in the middle and lower part of the front end of the mixer, arranged from left to right in sequence; the universal casters are arranged at the four corners of the bottom surface of the mixer: the structure is simple, the practicability is strong, the safety is high, the service life is long, and it is suitable for popularization and use;

[0005] Combined with current practical applications, it is found that the current solder paste mixer still has certain disadvantages when used, such as:

[0006] The stirring position is fixed. The installation direction of the solder paste tank is fixed. Due to the centrifugal effect during stirring, part of the raw materials inside the solder paste tank will always stick to the side wall of the solder paste tank, affecting the mixing quality;

[0007] The workstation is fixed. The current solder paste mixer is generally equipped with a double workstation for mixing when performing solder paste mixing operations. Its structure is fixed, which is not conducive to the mixing of multiple groups of solder paste tanks.

[0008] The fixing method is single, and it is not possible to stably limit the use of the solder paste can, and it is not possible to fix the solder paste cans of different heights;

[0009] Therefore, we propose a solder paste mixer that is conducive to sufficient mixing, so as to solve the above-mentioned problems. Summary of the invention
