[0002] In the field of chip manufacturing, quartz sand is an important basic material. The quality of its molded parts directly affects the performance and yield of the chip. With the continuous development of chip technology, the requirements for the precision and purity of quartz sand molded parts are getting higher and higher. Traditional quartz sand molding equipment often has the problem of insufficient grinding precision, which cannot effectively grind quartz sand to the particle size required for chip manufacturing, resulting in substandard quality of molded parts.

[0003] Some equipment uses multi-stage motors to drive different grinding stages. Although it can achieve the grinding function, the power system is complex, which not only increases the cost of equipment and energy consumption, but also makes it prone to power transmission failures, affecting the continuity of production. Moreover, many pieces of equipment have loose structures and occupy a large area. In modern production workshops where every inch of space is precious, the space utilization rate is low, which is not conducive to the company's expansion of production scale.

[0004] In addition, existing quartz sand molding equipment has poor adaptability to raw materials, making it difficult to meet the processing requirements of quartz sand raw materials of different qualities and unable to flexibly cope with diversified production tasks.

[0005] Therefore, developing a quartz sand molding equipment for chip fabrication that features fine grinding, high power efficiency, compact structure, and strong adaptability has become an urgent problem to be solved in the chip manufacturing industry. This equipment solution is proposed based on this background. Utility Model Content

[0030] Please see Figure 1-4This utility model provides a technical solution: a quartz sand molding device for chip preparation, including a support 1, a coarse grinding box 4 fixedly connected to the support 1, a feed hopper 2 fixedly connected to the coarse grinding box 4, and a screen 3 fixedly connected to the bottom of the feed hopper 2;

[0031] A motor 5 is fixedly connected to the bracket 1. A transmission device 6 is fixedly connected to the output end of the motor 5. The transmission device 6 includes a transmission belt, transmission gears and a transmission shaft. The motor 5 is fixedly connected to a coarse grinding roller 7 through the transmission device 6. The coarse grinding roller 7 is located inside the coarse grinding box 4 and is provided with three coarse grinding rollers 7 meshing and grinding.

[0032] A guide pipe 8 is fixedly connected to the bottom of the coarse grinding box 4. A fine grinding box 9 is fixedly connected to the bottom of the guide pipe 8. A fine grinding roller 10 is fixedly connected to the fine grinding box 9. A fine grinding plate 11 is fixedly connected inside the fine grinding box 9. The fine grinding plate 11 is arc-shaped and surrounds the fine grinding roller 10. Springs are provided at the connection between the fine grinding plate 11 and the two sides inside the fine grinding box 9. The motor 5 drives the fine grinding roller 10 to roll and grind on the fine grinding plate 11 through the transmission device 6.

[0033] A filter screen 12 is fixedly connected to the bottom of the fine grinding box 9. A guide hopper 13 is located below the filter screen 12. A high-temperature furnace 14 is fixedly connected to the bottom of the fine grinding box 9. A guide pipe 15 is fixedly connected to the output end of the high-temperature furnace 14. A pressing device 16 is fixedly connected to one end of the guide pipe 15.

[0034] The high-temperature furnace 14 and the molding device 16 are known technical means. For those skilled in the art, these technical means can be easily implemented without the need for creative experiments, and will not be described in detail here.

[0035] Working principle: Using the quartz sand molding equipment for chip preparation, the quartz sand raw material is poured into the feed hopper 2. Under its own gravity, the raw material is initially filtered through the screen 3 to remove larger particles of impurities before entering the coarse grinding box 4.

[0036] At this time, the motor 5 starts, and its output end transmits power to the three coarse grinding rollers 7 in the coarse grinding box 4 through the transmission device 6. The three coarse grinding rollers 7 mesh with each other and rotate to coarsely grind the quartz sand, so that the quartz sand particles are initially crushed and refined.

[0037] After coarse grinding, the quartz sand enters the fine grinding box 9 through the guide pipe 8 at the bottom of the coarse grinding box 4. In the fine grinding box 9, the motor 5 continues to drive the fine grinding roller 10 to rotate through the transmission device 6. The fine grinding roller 10 rolls on the arc-shaped fine grinding plate 11.

[0038] Because springs are provided at the connection points between the fine grinding plate 11 and the two sides inside the fine grinding box 9, the fine grinding plate 11 can adaptively adjust its fit with the fine grinding roller 10 under the action of the springs, thereby achieving fine grinding of the quartz sand, further reducing the particle size of the quartz sand, and making it reach the required fineness.

[0039] The finely ground quartz sand falls under the action of gravity and passes through the filter screen 12 at the bottom of the fine grinding box 9 to screen out larger unqualified particles. The qualified quartz sand enters the high-temperature furnace 14 through the feed hopper 13.

[0040] The high-temperature furnace 14 heats the quartz sand at high temperature, melting it and bringing it to a plastic state. Then, the molten quartz sand is transported to the molding device 16 through the guide pipe 15. Under the pressure of the molding device 16, it is cooled and shaped into the quartz sand molding parts required for chip fabrication.

[0041] The system employs a two-stage grinding structure consisting of a coarse grinding box 4 and a fine grinding box 9. The coarse grinding rollers 7 mesh with each other for initial crushing, while the fine grinding rollers 10 work in conjunction with an adaptively adjustable fine grinding plate 11 for fine grinding. This effectively grinds the quartz sand to the particle size required for chip fabrication, ensuring product quality.

[0042] Using a single motor 5, the coarse grinding roller 7 and the fine grinding roller 10 are driven simultaneously through a transmission device 6. This reduces the number of power components in the equipment, lowers equipment costs and energy consumption, simplifies the power transmission system, and improves the overall operational stability.

[0043] The coarse grinding box 4, fine grinding box 9, high-temperature furnace 14, etc. are connected in sequence, with a compact layout and small footprint, which is suitable for production workshops with limited space. It is also convenient for equipment installation, debugging and daily maintenance. From the feeding of quartz sand raw materials to the production of molded parts, the whole process realizes continuous operation, reduces intermediate manual intervention links, improves production efficiency, and can meet the batch demand of quartz sand molded parts for chip manufacturing.

[0044] By adjusting the rotation speed of the coarse grinding roller 7 and the fine grinding roller 10, as well as the fit between the fine grinding plate 11 and the fine grinding roller 10, it can be applied to quartz sand raw materials with different initial particle sizes and hardness, thus meeting diverse production needs.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
