[0002] A solder paste grinder is a specialized piece of equipment used to process solder paste. It is mainly used to grind the particles in the solder paste to the required particle size to meet the performance requirements of solder paste in electronic manufacturing. It refines the coarse particles in the solder paste through mechanical grinding while maintaining its fluidity, adhesion and other performance indicators to ensure soldering quality.

[0003] Existing solder paste grinding machines suffer from poor grinding effect because the solder paste particles cannot fully contact the grinding cone during actual use. Furthermore, it is inconvenient to quickly discharge the solder paste particles after grinding, resulting in low grinding efficiency. To address these issues, a high-precision grinding structure for solder paste production is proposed. Utility Model Content

This structure solves the technical problems of existing solder paste grinding machines in the background art, where solder paste particles cannot fully contact the grinding cone during actual use, resulting in poor grinding effect and inconvenience in quickly discharging the ground solder paste particles after grinding, leading to low grinding efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-precision grinding structure for solder paste production includes a grinding machine body.

[0008] Preferably, the lower ends of the grinding machine body near the four corners are fixedly installed with supports, the rear side wall of the grinding machine body is provided with an inspection port, the inspection port is connected to the rectangular cavity, and the left and right side walls near the lower end of the grinding machine body are provided with inclined discharge ports, both of which are connected to the conical bottom of the grinding machine body.

[0009] Preferably, two handles are fixedly installed at the upper end of the annular grinding cylinder, and the two handles are symmetrically distributed between each other. A plurality of conical grinding teeth are evenly distributed at equal intervals along the vertical direction.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A high-precision grinding structure for solder paste production includes a grinding machine body 1. A circular groove 2 is located at the upper center of the grinding machine body 1, with a conical bottom. Supports 14 are fixedly installed at the lower ends of the grinding machine body 1 near its four corners, providing stable support. An inspection port (not shown in the figure) is located on the rear side wall of the grinding machine body 1, communicating with a rectangular cavity 5. The inspection port is used for the installation and maintenance of a hydraulic cylinder 6. Inclined discharge ports 15 are located on the left and right side walls near the lower end of the grinding machine body 1. Both inclined discharge ports 15 are connected to the grinding machine body. The conical bottom of the grinding mill body 1 is connected, and the inclined discharge port 15 is used to discharge the grinding particles on the conical bottom of the circular groove 2. Two handles 16 are fixedly installed on the upper end of the annular grinding cylinder 3. The two handles 16 are symmetrically distributed between them. The two handles 16 are used to place or lift the annular grinding cylinder 3. The upper end of the grinding mill body 1 is provided with a rectangular annular slot 17. A rectangular annular baffle 18 is inserted into the rectangular annular slot 17. The circular groove 2 is located in the rectangular annular baffle 18. The rectangular annular baffle 18 is inserted into the rectangular annular slot 17 to prevent solder paste particles from splashing out during the grinding process.

[0023] An annular grinding cylinder 3 is inserted into the circular groove 2. Several conical grinding teeth 4 are fixedly installed on the annular inner wall of the annular grinding cylinder 3. These conical grinding teeth 4 are evenly distributed at equal intervals along the vertical direction. The conical grinding teeth 4 are made of wear-resistant alloy. First, the annular grinding cylinder 3 is inserted into the circular groove 2, and the hydraulic cylinder 6 in the rectangular cavity 5 is activated. This causes the hydraulic cylinder 6, in conjunction with the fixed base 8 and the drive motor 10, to drive the circular cover 7 to cover the lower end of the annular grinding cylinder 3. The solder paste particles to be ground are then placed inside the annular grinding cylinder 3. The drive motor 10 in the mounting groove 9 is then activated. The rotating spiral stirring rod 13 continuously flips the solder paste particles inside the annular grinding cylinder 3, allowing the solder paste particles to fully contact and collide with the several conical grinding teeth 4 evenly distributed vertically inside the annular grinding cylinder 3, thus improving the grinding effect. The grinding machine body 1 is located in the rectangular cavity 5 inside the conical bottom. A hydraulic cylinder 6 is fixedly installed on the bottom of the rectangular cavity 5. The upper end of the piston rod of the hydraulic cylinder 6 is vertically inserted through the top surface of the rectangular cavity 5. The hydraulic cylinder 6 is used to control the height of the circular cover 7 and the drive motor 10.

[0024] A flipping mechanism is fixedly connected to the upper end of the piston rod of the hydraulic cylinder 6. The flipping mechanism is inserted into the annular grinding cylinder 3. A circular cover 7 is provided on the flipping mechanism, which covers the lower end of the annular grinding cylinder 3. The flipping mechanism includes a fixed seat 8 fixedly installed on the upper end of the piston rod of the hydraulic cylinder 6. The upper end of the fixed seat 8 is provided with a mounting groove 9. A drive motor 10 is placed in the mounting groove 9. The lower end of the drive motor 10 is provided with a mounting seat 11. Several bolts 12 are fixedly connected between the fixed seat 8 and the mounting seat 11. The bolts 12 are used to fix the mounting seat 11 in the mounting groove 9. A spiral stirring rod 13 is fixedly connected to the upper end of the drive motor 10. The spiral stirring rod 13 rotates vertically, passes through the center of the circular cover 7, and extends into the annular grinding cylinder 3. The spiral stirring rod 13 can continuously flip the solder paste particles in the annular grinding cylinder 3, so that the solder paste particles can fully contact and collide with the several conical grinding teeth 4 that are evenly distributed in the vertical direction in the annular grinding cylinder 3, thereby improving the grinding effect.

[0025] In use, the annular grinding cylinder 3 is first inserted into the circular groove 2, and the hydraulic cylinder 6 in the rectangular cavity 5 is activated. The hydraulic cylinder 6, in conjunction with the fixed base 8 and the drive motor 10, causes the circular cover 7 to be placed over the lower end of the annular grinding cylinder 3. The solder paste particles to be ground are then placed inside the annular grinding cylinder 3. The drive motor 10 in the mounting groove 9 is then activated, causing the spiral stirring rod 13 to rotate. This causes the spiral stirring rod 13 to continuously rotate the solder paste particles inside the annular grinding cylinder 3, allowing the solder paste particles to fully contact and collide with the several equally spaced, vertically distributed conical grinding teeth 4 inside the annular grinding cylinder 3, thus improving the grinding effect. To improve the grinding effect, a rectangular ring baffle 18 is inserted into a rectangular ring slot 17 to prevent solder paste particles from splashing out during the grinding process. After grinding is completed, the hydraulic cylinder 6 is activated to separate the circular cover 7 from the annular grinding cylinder 3, and the handle 16 is used to lift the annular grinding cylinder 3 out of the circular groove 2. The solder paste particles after grinding fall directly onto the conical bottom of the circular groove 2. The drive motor 10 is activated again to drive the spiral stirring rod 13 and the circular cover 7 to rotate, quickly discharging the grinding particles stuck on the circular cover 7 into the conical bottom, and then quickly discharging them through the inclined discharge port 15, which facilitates rapid discharge and improves grinding efficiency.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
