[0016] The following detailed implementation will further illustrate the present application in combination with the above drawings. DETAILED DESCRIPTION

[0017] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The drawings show several embodiments of the present application. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can be a middle element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0020] Referring to Figs. 1-2 The ceramic nozzle roughening treatment ceramic nozzle splitting knife provided by the embodiment of the application comprises a cylindrical portion 1, a ceramic nozzle neck portion 2, and a ceramic nozzle portion 3. One end of the cylindrical portion 1 is in the shape of a circular truncated cone. The circular truncated cone end of the cylindrical portion 1 is connected to one end of the ceramic nozzle neck portion 2. The ceramic nozzle neck portion 2 is connected to the ceramic nozzle portion 3 away from one end of the cylindrical portion 1. The ceramic nozzle portion 3 is provided with a plurality of grooves 7 away from one end of the ceramic nozzle neck portion 2. The side walls of the plurality of grooves 7 and the end face of the ceramic nozzle portion 3 away from one end of the ceramic nozzle neck portion 3 form a concave-convex welding surface 4. The ceramic nozzle portion 3 is provided with a ceramic nozzle opening 5 at the center of the welding surface 4.

[0021] It should be noted that the ceramic nozzle splitting knife is provided with a through hole for passing through a welding wire. One end of the through hole is connected to the ceramic nozzle opening 5. When the ceramic nozzle splitting knife is installed, the welding wire is inserted into the through hole and finally extends out from the ceramic nozzle opening 5. When the ceramic nozzle splitting knife is used, the ceramic nozzle splitting knife is installed on an ultrasonic transducer of a welding machine. Under the high energy of the welding machine, the welding wire is melted between the ceramic nozzle portion 3 and a solder pad. At this time, the ceramic nozzle welding surface 4 is processed in a concave-convex shape, so that the surface is roughened. The melted welding wire also has a certain grid shape after solidification, thereby enhancing the adhesion of the welding wire and the support functional area, and improving the firmness of the welding.

[0022] In the embodiment, the welding surface 4 comprises a first welding surface 41 and a second welding surface 42. The first welding surface 41 is smoothly connected to the second welding surface 42. The first welding surface 41 is in the shape of a micro-arch. This facilitates the pressing of the welding wire during welding, thereby improving the adhesion of the welding wire and the support. The second welding surface 42 facilitates the oblique welding of the ceramic nozzle splitting knife. The smooth connection of the first welding surface 41 to the second welding surface 42 avoids the generation of stress during welding, thereby reducing the firmness of the welding. Specifically, the welding surface 4 comprises the first welding surface 41 and the second welding surface 42. The second welding surface 42 is arranged close to the side of the ceramic nozzle portion 3.

[0023] Further, the diameter of one end of the cylindrical portion 1 close to the ceramic nozzle neck portion 2 is smaller than the diameter of one end of the cylindrical portion 1 away from the ceramic nozzle neck portion 2. By setting one end of the cylindrical portion 1 in the shape of a circular truncated cone, the connection of the ceramic nozzle neck portion 2 is facilitated, and the appearance is more beautiful. In addition, the field of view during welding is better.

[0024] In practical application, for some areas with small pad spacing, using ordinary ceramic nozzle welding knife directly for welding, it is difficult to weld directly, or it can be welded, but the welding point of view is blocked by the cylindrical part 1, which is not convenient to operate; in order to solve this problem, in this embodiment, a ceramic nozzle neck 2 is installed between the cylindrical part 1 and the ceramic nozzle part 3, by setting the ceramic nozzle neck 2 as a slender cylinder, so that the ceramic nozzle part 3 can be inserted into a deeper and smaller gap for welding, and the welding field is better, and the welding precision is improved; further, the ceramic nozzle neck 2 is cylindrically arranged, and the diameter of the ceramic nozzle neck 2 is smaller than the diameter of the circular table end of the cylindrical part 1.

[0025] Further, the ceramic nozzle part 3 is arranged in a circular table shape, the diameter of the ceramic nozzle part 3 close to one end of the ceramic nozzle neck 2 is equal to the diameter of the ceramic nozzle neck 2, and the diameter of the ceramic nozzle part 3 away from one end of the ceramic nozzle neck 2 is smaller than the diameter of the ceramic nozzle part 3 close to one end of the ceramic nozzle neck 2, by setting the ceramic nozzle part 3 in a circular table shape, the welding ability of the ceramic nozzle welding knife in a narrow area is further improved. In addition, it should be noted that the inclination angle of the ceramic nozzle part 3 in the circular table shape should be set between 30° and 45°, too large makes the welding surface 4 too small, which is not conducive to welding, too small has no obvious effect, and increases the process difficulty.

[0026] Referring to Fig. 2 In this embodiment, the ceramic nozzle mouth 5 is arranged in a horn shape, which makes the molten welding wire have enough storage space when the ceramic nozzle welding knife is welded, and also reduces the problem of welding wire blocking the ceramic nozzle mouth 5.

[0027] In summary, the ceramic nozzle wedge knife in the above embodiment of the utility model roughens the ceramic nozzle part, so that the welding surface is roughened, and the welded welding surface is more firm. In addition, by arranging the ceramic nozzle neck, the ceramic nozzle wedge knife can weld the area with small pad space, and the welding field during welding is improved, and the welding precision is increased.
