Description

a perfusion system

Technical field

The invention relates to the field of machinery, and in particular to a perfusion system.

Background technique

Micromolding is a high-precision nanofabrication technology that uses microreplicated molds to shape microstructures. Micromolding has the advantages of high replication accuracy, low cost, and small residual stress. It is widely used in the preparation of nanostructures such as microgears, microneedles, microfluidic chips, and light guide plates in various fields such as machinery, medicine, and biology.

The most critical step in micro-molding is mold filling, that is, filling the replication liquid material into the molding cavity of the mold with a high filling ratio, which is a key factor affecting the accuracy of microstructure replication. Commonly used mold filling methods include pressure filling, vacuum filling, etc. Among them, pressure filling refers to using pressure to press the filling material into the molding cavity of the mold. In this regard, molds are usually made by metal one-piece molding. However, it is very difficult to use metal one-piece molding to process structures with the same height and width ratio and high precision such as microneedle molds. Therefore, microneedle molds are often used. Made of silicone or polymer materials. However, silicon materials are usually brittle, and polymer materials are soft and have strict requirements on compressive stress, making them unsuitable for mass production. In contrast, vacuum filling has low requirements on mold material and size compatibility, has more obvious advantages, and is more widely used. The current vacuum filling method usually lays the raw materials flat on the surface of the mold under normal pressure, and then evacuates the residual gas inside the mold to allow the raw materials to enter the microstructure of the mold. However, there are many problems with this method. For example, if the raw material is laid with a large thickness, the process of removing the residual gas through vacuuming will result in incomplete removal of the residual gas. As a result, the residual gas in the raw material will eventually lead to the existence of bubbles in the product, which will affect the product. Quality, and the thicker laying of raw materials also causes waste of raw materials, resulting in increased production costs. When the thickness of the raw material laying is small, after vacuuming to remove the residual gas, the raw material will enter the molding cavity but cannot completely fill the molding cavity, resulting in a lack of raw materials and affecting product performance. In addition, during the laying process of raw materials, it is easy to have uneven thickness, with some areas having larger thicknesses, some areas having smaller thicknesses, or the surface of the mold being uneven, etc., which will affect the consistency of the raw materials entering the molding cavity. , ultimately affecting the quality of the product. In addition, it takes a long time for raw materials to enter the microstructure, which reduces production efficiency.

The port 4200 is selectively aligned with one of the molding cavities 230 (that is, the filling port 4200 and the molding cavity 230 aligned with it have the same coordinates on the XY plane), and then pass through the first The movement mechanism 5100 controls the filling assembly 4000 to move in the negative direction of the Z-axis, so that the filling port 4200 is close to the mold 200, and then the raw material can be poured into the molding cavity 230. The specific filling process is that the filling assembly 4000 first fills the molding cavity aligned with the raw material, and then again controls the flow between the filling assembly 4000 and the first stage 3100 through the X direction and/or Y The relative movement in the direction aligns the filling port 4200 with the other molding cavity 230 that is not vacuum-filled, and fills the raw material. That is to say, every time the raw material filling of a molding cavity is completed, the relative movement between the filling assembly 4000 and the first stage 3100 through the X direction and/or the Y direction is re-controlled, so that the filling port 4200 Align with the next non-vacuum-filled molding cavity 230 and inject raw materials until all the molding cavities 230 on the mold 200 are filled with raw materials. Finally, the first motion mechanism 5100 controls all the molding cavities 230 . The filling assembly 4000 moves along the positive direction of the Z-axis, so that the filling port 4200 moves away from the mold 200 . This filling method can accurately fill each molding cavity, reducing the waste of raw materials. At the same time, the raw materials directly enter the molding cavity without slowly infiltrating, shortening the filling time, reducing production costs, and during the filling process, even if the raw materials If the mold is not completely pressed into the molding cavity, it can also be used during the process of removing the filled mold from the housing 1000 (this process is a vacuum breaking process for the mold). The pressure difference between the inside and outside of the mold cavity 230 completely presses the raw material into the molding cavity, avoiding insufficient filling of the raw material in each molding cavity 230, improving the consistency of raw material filling, and improving the quality of the final product. In addition, the filling port 4200 also allows the raw material to be sprayed out in the shape of water droplets. In actual use, the operating parameters of the filling port 4200 can be set according to the opening size of the molding cavity 230, so that the filling port 4200 sprays out The diameter of the raw material is smaller than the opening size of the molding cavity 230, so that the raw material can be poured into the molding cavity 230 smoothly, avoiding waste caused by the raw material being sprayed to the outside of the molding cavity 230, and according to the volume of the molding cavity 230 The number of times the filling port injects the raw material into each molding cavity 230 is set to avoid insufficient filling of the raw material in each molding cavity 230, improve the consistency of raw material filling, and improve the quality of the final product. Preferably, the filling port 4200 is a striker-type nozzle.

It should be noted that in the embodiment of the present invention, any suitable device or method can be used to determine whether the filling port 4200 is aligned with a molding cavity 230. For example, when the filling system is started for the first time, the relative motion function of the first movement mechanism 5100 is first used to determine the relative positional relationship between the filling port 4200 and the first molding cavity 230 to determine the relationship between the filling port 4200 and the third molding cavity 230 . The relative position of the molding cavity 230 is determined, and the filling port 4200 is used to inject the raw material once, and it is observed whether the raw material accurately enters the molding cavity 230. If it enters, it is considered that the filling port 4200 is in contact with the molding cavity 230. The molding cavity 230 is aligned. Afterwards, the motion parameters of the first motion mechanism 5100 are controlled according to the relative positional relationship between the remaining molding cavities 230 and the first molding cavity 230 to realize that the filling port 4200 is sequentially connected to the other molding cavities. 230 alignment. In other implementations, alignment determination can also be achieved by setting up a laser alignment system, an optical alignment system or other alignment systems in the prior art, which is not limited in the embodiments of the present invention. Since the alignment determination device or method is not an improvement point of the present invention, it will not be described in detail here.
