Description

Technical Field

[0001] This utility model relates to the technical field of solder paste mixing devices, specifically to a solder paste mixer. Background Technology

[0002] Solder paste, also known as soldering paste, is a new type of soldering material that emerged with the development of surface mount technology (SMT). It is a paste-like mixture formed by mixing solder powder, flux, and other surfactants and thixotropic agents. Before use, solder paste needs to be thoroughly mixed to ensure soldering strength. A solder paste mixer can effectively mix the solder powder and flux evenly, and also removes air bubbles during the mixing process.

[0003] However, in existing solder paste mixers, the stirring rod always rotates in a fixed direction, which prevents the solder paste material from being mixed at different levels, resulting in insufficient mixing and affecting the quality of the material mixture. Utility Model Content

[0004] The purpose of this invention is to provide a solder paste mixer that solves the problem that in existing solder paste mixers, the stirring rod always rotates in a fixed direction, preventing the solder paste material from being mixed at different levels, resulting in insufficient mixing and affecting the quality of the mixed material.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A solder paste mixer includes a base with a vertical plate on it. A sliding block that slides vertically along its central axis is slidably connected to the side wall of the vertical plate. A horizontally arranged circular cover is connected to the sliding block. A vertically arranged cylinder is connected to the bottom side of the circular cover via a support rod. A motor is provided on the top side of the circular cover. The output shaft of the motor rotates vertically downward through the circular cover and is connected to a rotating rod placed inside the cylinder. A spiral blade is sleeved on the outer side of the rotating rod. A horizontally arranged crossbar is connected to the bottom end of the rotating rod. Two vertically arranged stirring rods are provided at both ends of the crossbar.

[0006] A further technical solution is that the two stirring rods are connected by the same stirring blade, and the stirring blade is arranged in a vertical spiral around the outside of the cylinder.

[0007] A further technical solution is to have two mounting plates symmetrically arranged on the top side of the base, each mounting plate being equipped with an electric telescopic rod. The telescopic ends of the electric telescopic rods are positioned opposite each other and connected to a fixing clamp.

[0008] A further technical solution is to provide a silicone pad on the opposite side of the fixing plate.

[0009] A further technical solution is that a dovetail groove is provided on the side wall of the vertical plate along its central axis, and the sliding block is adapted to the dovetail groove. A vertically arranged electric cylinder is provided at the bottom of the dovetail groove, and the extension and retraction end of the electric cylinder is fixedly connected to the sliding block.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In use, after the round cover is placed on the solder paste container, the motor is started to drive the rotating rod to rotate, which in turn drives the spiral blades and stirring rod to rotate. At this time, the spiral blades cooperate with the cylinder. The rotation of the spiral blades pushes the solder paste placed at the bottom of the solder paste container upward along the cylinder, while also stirring the solder paste. Finally, the solder paste overflows from the top of the cylinder and is placed above the solder paste in the solder paste container. The rotation of the stirring rod can stir the solder paste placed between the cylinder and the solder paste container. This process is repeated to achieve different levels of mixing of the solder paste material inside the solder paste container, ensuring the mixing effect. Attached Figure Description

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Example 1 Reference Figure 1 , Figure 2This utility model discloses a solder paste mixer, including a base 1, a vertical plate 2 on the base 1, a sliding block 3 that slides vertically along its central axis on the side wall of the vertical plate 2, a horizontally arranged circular cover 4 connected to the sliding block 3, and a vertically arranged cylinder 6 connected to the bottom side of the circular cover 4 via a support rod 5; a motor 7, which may be a servo motor 7, is provided on the top side of the circular cover 4, the output shaft of the motor 7 rotates vertically downward through the circular cover 4 and is connected to a rotating rod 8 placed inside the cylinder 6, a spiral blade 9 is sleeved on the outer side of the rotating rod 8, a horizontally arranged crossbar 10 is connected to the bottom end of the rotating rod 8, and two vertically arranged stirring rods 11 are provided at both ends of the crossbar 10.

[0017] In this embodiment, during use, the solder paste container 20 is placed on the base 1. The sliding block 3 slides downward, causing the round cover 4 to move downward, so that the rotating rod 8, the spiral blade 9, the stirring rod 11, and the cylinder 6 are placed in the solder paste container 20. After the round cover 4 is fastened on the solder paste container 20, the motor 7 is started to drive the rotating rod 8 to rotate, which in turn drives the spiral blade 9 and the stirring rod 11 to rotate. At this time, the spiral blade 9 cooperates with the cylinder 6. The rotation of the spiral blade 9 pushes the solder paste placed at the bottom of the solder paste container 20 to move upward along the cylinder 6, while also stirring the solder paste. Finally, the solder paste overflows from the top of the cylinder 6 and is placed above the solder paste in the solder paste container 20. The rotation of the stirring rod 11 can stir the solder paste placed between the cylinder 6 and the solder paste container 20. This process is repeated to achieve different levels of mixing of the solder paste material inside the solder paste container 20, ensuring the stirring effect.

[0018] It should be noted that when the round cover 4 is fastened onto the solder paste container 20, there is a gap between the bottom end of the cylinder 6 and the bottom side of the solder paste container 20 to ensure that the solder paste inside the solder paste container 20 can enter the cylinder 6. At the same time, the bottom end of the spiral blade 9 extends out of the bottom end of the cylinder 6 and has a gap with the bottom side of the solder paste container 20.

[0019] Example 2 Based on Example 1, referring to Figures 1 to 3 The two stirring rods 11 are connected by the same stirring blade 12, which is arranged in a vertical spiral around the outside of the cylinder 6.

[0020] In this embodiment, when the stirring rod 11 rotates to stir the solder paste placed between the cylinder 6 and the solder paste container 20, it will drive the stirring blade 12 to rotate around the outside of the cylinder 6, thereby pushing the solder paste placed between the cylinder 6 and the solder paste container 20 towards the bottom of the solder paste container 20, ensuring that the solder paste at the bottom of the solder paste container 20 can move smoothly upward along the cylinder 6 under the action of the spiral blade 9. It should be noted that the spiral direction of the stirring blade 12 is set opposite to the direction of the spiral blade 9, so that when the rotation directions of the stirring blade 12 and the spiral blade 9 are the same, the spiral blade 9 pushes the solder paste in the cylinder 6 to move up and down, and the stirring blade 12 pushes the solder paste between the cylinder 6 and the solder paste container 20 to move downward.

[0021] Example 3 Based on Example 1, referring to Figure 1 The base 1 has two symmetrical mounting plates 13 on its top side. Each mounting plate 13 is equipped with an electric telescopic rod 14. The telescopic ends of the electric telescopic rods 14 are arranged opposite each other and connected to a fixing clamp 15.

[0022] In this embodiment, during use, the solder paste container 20 is placed on the base 1, and the extension end of the electric telescopic rod 14 is extended to drive the fixing clamp 15 to move toward the outside of the solder paste container 20, thereby clamping and fixing the solder paste container 20. The fixing clamp 15 can be arc-shaped to better fit the outer wall of the solder paste container 20.

[0023] As a preferred embodiment, a silicone pad is provided on the opposite side of the fixing plate 15. Specifically, by providing the silicone pad, the friction can be increased to ensure the stability of the solder paste container 20 when it is clamped and fixed.

[0024] Example 4 Based on Example 1, referring to Figure 1 A dovetail groove 16 is provided on the side wall of the vertical plate 2 along its central axis. The sliding block 3 is adapted to the dovetail groove 16. A vertically arranged electric cylinder 17 is provided at the bottom of the dovetail groove 16. The extension end of the electric cylinder 17 is fixedly connected to the sliding block 3.

[0025] In this embodiment, during use, the electric cylinder 17 can be controlled to drive the sliding block 3 to move along the dovetail groove 16, thereby driving the round cover 4 to move up and down, so as to drive the rotating rod 8, the spiral blade 9, the stirring rod 11 and the cylinder 6 to be placed in the solder paste container 20, and the round cover 4 to be fastened on the solder paste container 20.

[0026] It should be noted that, in the above embodiments, the use of a control console to control the operation of the motor 7, the electric telescopic rod 14, and the electric cylinder 17 is common knowledge to those skilled in the art, and those skilled in the art can directly obtain the corresponding installation relationship and structure based on common knowledge, so it will not be described in detail here.

[0027] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims.
