I: Prior Art 3 Background of the Invention When coating a fluid material such as a gap filler or an EMI shielding sealing material, a circular paste strip of the fluid material is usually placed on a substrate. The so-called "fluid" in this field 10 generally refers to a material that can exhibit fluid-like properties and can be extruded through a cloth nozzle. However, when filling non-circular cross-sections: circular paste strips using this fluid material are not ideal. For example, when a substrate (such as a shell) has a rectangular channel to be filled, if it is a circular paste, it usually takes several times to properly fill the channel. This will take 15 more hours and increase manufacturing costs. Similarly, the circular paste often does not provide a non-circular cross-section to provide the best filling fit. One way to solve this problem is to match the orifice of the cloth distribution nozzle to the section to be filled. Because, matching the orifice of the cloth-distributing nozzle to the cross-section to be filled will advantageously enable the process to be completed in only one pass, and at the same time achieve a tighter filling of 20 to better than a circular paste. The manufacturing of these specific distribution nozzles should be simple and cost effective. It is therefore an object of the present invention to provide a simple method for manufacturing a distribution nozzle having a complicated cross section. [Summary of the Invention] 5 200400085 Summary of the Invention The present invention is a method for manufacturing a nozzle for a fluid material. The nozzle is capable of generating a paste strip with a complex cross section on a substrate. The method includes a step of preparing a mandrel of the cloth dispensing nozzle. The mandrel has a part of a 5-inch shape that essentially matches the complex cross section. A section of heat-shrinkable tube will be sleeved on the mandrel, and the tube will be heated to shrink and contact the mandrel to form the distribution nozzle. The present invention will now be described in more complete detail with reference to the following drawings. Brief description of the drawings 10 Figure 1 is a partial cross-sectional view of a two-piece housing, which has opposite channels. When mated, a non-circular cross-section can be formed to accept first-class materials. Fig. 2 is a side view of a nozzle for fabric distribution, the nozzle having an orifice matching a non-circular cross section formed by the two-piece housing of Fig. 1. Fig. 3 is a side view of the mandrel part of Fig. 2 inserted into a 15 heat shrinkable tube used to make a cloth nozzle. Fig. 4 is a side view of the mandrel part of Fig. 2 sleeved into the heat-shrinkable tube, and the tube is heated and shrunk on the outer surface of the mandrel to form the cloth distribution nozzle of the present invention. Fig. 5 is a cross-sectional view of the nozzle in Fig. 4 taken along the line 5-5, which has a 20-hole opening to match the non-circular cross-section formed by the two-piece housing of Fig. 1. Fig. 6 is a partial cross-sectional view of one of the cases of Fig. 1, and a non-circular cross-section of a first-class material having a nozzle arranged in Fig. 5 is provided in the passage. Figures 7, 7A, 8 and 8A show a method of making a self-made nozzle with an injection joint to form a spray nozzle that can be used immediately with standard extrusion equipment. 6 200400085 · Figures 7A and 8A, respectively Figures 7 and 8 are sectional views. [Embodiment 2 Detailed Description of Preferred Embodiments] According to the present invention, a simple method 5 for manufacturing a specific set of assembly cloth nozzles is provided. Nozzles for fluid materials (such as interstitials, EMI shielding sealing materials, etc.) are usually extruded into a circular paste. However, in order to reduce the manufacturing time and obtain better adhesion, it is best to make the strip of liquid material match the complex shape to be filled. The method for manufacturing a cloth matching nozzle according to the method of the present invention includes: preparing a mandrel (mold core) for the cloth matching nozzle, and a part of the 10 mandrel has a size and shape that completely matches the complex section; A length of a heat-shrinkable tube is sleeved on the mandrel; and the tube is heated to shrink and contact the mandrel to form the distribution nozzle. The method of the present invention can be better understood with reference to the drawings. Referring to Fig. 1, an example of a substrate is shown, which has a surface capable of supporting 15 nanometers of high-quality materials, and is preferably extruded by a cloth dispensing nozzle according to the present invention. The β-sea substrate is a two-piece housing 10 and is arranged opposite to each other. The lower casing 12 includes a channel 14 to form a rectangular cross section (that is, a complex section, a corresponding upper casing 16 having a corresponding channel 18 is shown in an opposite direction. The two channels 14 and 18 are combined in the opposite direction. Will form a square cross-section (ie a complex cross-section). As known to those skilled in the art, the complex cross-section refers to any non-circular or semi-circular Sections. Therefore, examples of such complex sections can be square, rectangular, or any other polygonal section. After the desired shape and size of Tian Qian's cross section is determined, the mandrel (die core) 7 200400085 will be made to For the subsequent process of the cloth nozzle. The mandrel can be made using any technique known in the art. The mandrel is made of a heat-resistant material such as a heat-resistant metal such as carbon steel or stainless steel. . Preferably, the mandrel system is made of a metal blank (such as a rod) to the required size to make it into 50%. For example, the mandrel can be made from a metal rod with a seat. As shown in Figure 2, the mandrel 20 is made of a gold The rod 22 is made to have a chamfered portion 24 as a transition area to the rectangular portion 26. However, if it is not necessary to convert to the rectangular portion 26, the chamfered portion 24 can also be easily The size of the rod 22 is preferably convenient for the manufactured distribution nozzle to communicate with the first-class material supply source. According to the present invention, the square section of the rectangular portion 26 (not shown in the first section) (2), it will exactly match the square cross-section formed by the two channels 14, 18 of the casing 10. The distribution nozzle draws a length of the heat-shrinkable tube 100 as shown in Figure 3. It is made by covering the mandrel 20. Therefore, the tube 100 will form a surrounding relationship with the rectangular 15 portion 26, the chamfered portion 24, the rod 22, and the like. An effective amount of heat ray will be added to the mandrel. 20 and tube 100. The heat-shrinkable plastic tube used in the present invention is well known in the art. As shown in Figure 4, the ® tube 100 will shrink and fully contact the mandrel 20, so It will match the shape of the mandrel 20 to make a special shape extrusion nozzle. The shaped tube 100 (now 20% for cloth spraying) ) There is a square hole 102 in the cross section, which will exactly match the square cross section formed by the channels 14 and 18 of the housing 10, as shown in Figure 5. The distribution nozzle 100 嗣 will be released by the mandrel 20, and if If necessary, it can be cut to any specific length, as long as the cross-section of the orifice 102 remains the same. The cloth nozzle made according to the present invention is used to squeeze the fluid material (that is, 8 200400085 cloth) on the substrate. The coating machine is known in the field. The fluid material can be manually applied to the substrate by an interstitial gun or similar device that communicates with the distribution nozzle. An autoinjector material such as itself has two or More degrees of freedom of movement (x-y_z), or a robot applicator 5 combined with a movable station, etc. can also be used for mass production. The position of the nozzle on the substrate can be changed, and its range can be changed from a position perpendicular to the substrate to a position parallel to the substrate. As shown in Figure 6, when the nozzle 100 is used with an extruder (not shown) provided with a channel 14, the extruded fluid material 104 will have the required cross section. 10 Please refer to the figures 7, 7A, 8, 8A, etc. Before the heat shrink tube 100 is heated, an injection joint 110 may be connected at one end, which is made of a heat-resistant material such as heat-resistant plastic. Preferably, the joint 110 is inserted into the tube 100 at an end opposite to the mandrel 112. As shown in Figures 8 and 8A, the tube 100 will be shrink-fitted to the mandrel 112 and the joint 110, with a certain 15 蜇 aperture at one end (that is, a non-semi-circular cross section), and at the other end Standard orifices can be attached to the extruder as described above. The advantage of having an injection connector 110 is that the special nozzle can be immediately connected to the extruder without further modification. From the above description, it will be readily understood that the present invention provides a very simple method for manufacturing a cloth nozzle with a specific shape. The use of heat-shrinkable tubes can avoid many of the more cumbersome and expensive techniques such as injection molding. Therefore, a specific-shaped distribution nozzle can be made more easily and economically.
