Description

Technical Field

[0001] The utility model relates to a wire material processing system, in particular to a system for increasing the surface roughness of the wire material. Background Art

[0002] In the electronic packaging process, metal wires are usually used to connect chips and packages, while glass beads are used as one of the packaging materials. Improving the bonding strength between wires and glass beads can enhance the overall reliability of the package and ensure the stability and durability of electronic devices under various conditions of use. Wires may be subjected to mechanical or thermal stress. Improving the bonding strength between wires and glass beads can reduce the risk of wire breakage and improve the long-term stability of the device. Electronic devices generate heat during operation, and good heat conduction is essential for the performance and life of the device. The close bonding of metal wires and glass beads can improve the heat conduction path and help the device dissipate heat more effectively.

[0003] In the processing of metal wires, in order to improve the bonding strength between the wires and glass beads, it is usually necessary to pre-treat the wire surface to increase its roughness. Traditional pre-treatment methods include mechanical grinding, pickling, etc. These methods are not only inefficient, but also difficult to achieve uniform surface roughness, affecting the subsequent glass bead sintering process. Therefore, the development of an efficient and uniform metal wire surface treatment technology is of great significance to improve the bonding quality of wires and glass beads. Utility Model Content

[0004] The purpose of the utility model is to provide a system for increasing the surface roughness of a wire in order to overcome the defects of the above-mentioned prior art. By adopting multi-directional sandblasting technology, the roughness of the surface of the metal wire is improved, and the bonding strength between the wire and the glass beads is enhanced, thereby significantly improving the reliability, durability and electrical performance of the metal wire in electronic packaging applications.

[0005] During the process of conception, the applicant believed that sandblasting technology, as a surface treatment method, can effectively remove the oxide layer and increase the surface roughness by using high-speed airflow to impact the metal surface. This provides ideal surface conditions for glass bead sintering. However, traditional sandblasting equipment can only achieve one-way sandblasting, and it is difficult to ensure that the surface roughness of the metal wire is uniform in all directions, which is crucial to improving the bonding strength between the wire and the glass beads.

[0006] During the process of conception, the applicant believed that in order to achieve a uniform increase in the surface roughness of metal wires, multi-directional sandblasting technology is required. However, the existing multi-directional sandblasting system has problems such as complex design and inconvenient operation, and air flow collisions are easily generated during the sandblasting process, affecting the sandblasting effect. In addition, the recycling of abrasives and environmental protection are also problems that need to be solved in the prior art. Therefore, designing a multi-directional sandblasting system with a simple structure, easy operation, uniform sandblasting effect and environmental protection is of great significance to improving the surface treatment quality of metal wires.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] The utility model discloses a system for increasing the surface roughness of a wire, comprising a sandblasting chamber, a plurality of sandblasting modules, a wire reel, and an air compressor, wherein:

[0009] The sandblasting room is a closed shell structure;

[0010] A plurality of sandblasting modules are fixed in four orthogonal directions in the sandblasting room, and metal wires enter the sandblasting room and are sprayed by sand-containing airflows from four orthogonal directions;

[0011] A wire coiler, disposed on one side of the plurality of sandblasting modules, for coiling the metal wire after sandblasting;

[0012] An air compressor is connected to each of the sandblasting modules and is used to provide compressed air to the sandblasting modules.

[0013] Furthermore, the sandblasting module is a press-in dry sandblasting machine.

[0014] Furthermore, a mounting frame is provided in the sandblasting chamber, and the multiple sandblasting modules are all arranged on the mounting frame.

[0015] Furthermore, at least one sandblasting module is provided in four orthogonal directions in the sandblasting chamber.

[0016] Furthermore, two sandblasting modules are respectively arranged in four orthogonal directions in the sandblasting chamber.

[0017] Furthermore, in the length direction of the metal wire, the nozzles of each sandblasting module are staggered to avoid collision of airflows.

[0018] Furthermore, a sand recovery component is provided in the sand blasting chamber, and the sand recovery component is used to suck the sand deposited at the bottom of the sand blasting chamber back into the sand hopper of the pressurized dry sand blasting machine.

[0019] Furthermore, the sand recovery assembly includes a suction pipe, a pump connected to the suction pipe, and a plurality of delivery pipelines connected to the pump, and the plurality of delivery pipelines are respectively connected to the sand bucket of the sand blasting module.

[0020] Furthermore, a section of the suction pipe is placed at the bottom of the sandblasting chamber, and a plurality of suction ports are provided on the section of the suction pipe placed at the bottom of the sandblasting chamber.

[0021] Furthermore, an industrial camera module is provided between the sandblasting room and the wire reel, and the industrial camera module includes four orthogonally arranged industrial cameras, so as to obtain sample photos of the metal wire at four angles.

[0022] Compared with the prior art, the utility model has the following technical advantages:

[0023] 1) The utility model realizes that the metal wire is sprayed with sand-containing airflow in four orthogonal directions at the same time by arranging multiple sandblasting modules in the sandblasting chamber. This design significantly improves the efficiency of wire surface treatment. Since the wire can be evenly sandblasted from different directions when passing through the sandblasting chamber, the processing time can be shortened and the production efficiency can be improved.

[0024] 2) The utility model can avoid airflow collision and ensure that the surface of the metal wire is uniformly sandblasted by arranging at least one sandblasting module in four orthogonal directions in the sandblasting room and staggering the nozzles. This design helps to improve the consistency of the surface roughness of the wire, thereby improving the quality and effect of subsequent coating or bonding processes.

[0025] 3) The sand recovery component design in the utility model can effectively recover the sand deposited at the bottom of the sandblasting room and re-transport it to the sand hopper of the sandblasting module through the cooperation of the suction pipe, pump and delivery pipeline. This recycling mechanism not only reduces material waste and production costs, but also helps to maintain the continuity and stability of the sandblasting process, while reducing the impact on the environment.

[0028] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Component models, material names, connection structures, control methods, algorithms and other features not clearly described in this technical solution are all considered to be common technical features disclosed in the prior art.

[0029] Example 1

[0030] The utility model discloses a system for increasing the surface roughness of a wire, comprising a sandblasting chamber 1, a plurality of sandblasting modules 2, a wire reel 4, and an air compressor 5, wherein the system comprises ... Figure 1 .

[0031] The sandblasting room 1 is a closed shell structure; a plurality of sandblasting modules 2 are fixed in four orthogonal directions in the sandblasting room 1, and a metal wire 3 enters the sandblasting room 1 and is sprayed by sand-containing airflows from four orthogonal directions.

[0032] The wire reel 4 is disposed on one side of the plurality of sandblasting modules 2, and is used to reel in the metal wire 3 after the sandblasting process. The wire reel 4 is an existing device, and will not be described in detail herein.

[0033] The air compressor 5 is connected to each of the sandblasting modules 2 to provide compressed air to the sandblasting modules 2 .

[0034] The sandblasting module 2 is a press-in dry sandblasting machine. A mounting frame 10 is provided in the sandblasting room 1, and the plurality of sandblasting modules 2 are all provided on the mounting frame 10. In a specific implementation, two sandblasting modules 2 are provided in each of the four orthogonal directions in the sandblasting room 1, such as Figure 1 The form of two periodic distributions is adopted. In the length direction of the metal wire 3, the nozzles of each sandblasting module 2 are staggered to avoid the collision of airflow. Multi-directional sandblasting: By arranging two sandblasting modules in each of the four orthogonal directions in the sandblasting room, all-round sandblasting treatment of the metal wire 3 is achieved, ensuring that the surface of the wire can obtain uniform roughness in all directions. A press-in dry sandblasting machine is used as the sandblasting module 2. This equipment can effectively mix compressed air and abrasives such as sand particles to form a high-speed sand-containing airflow to impact the surface of the metal wire and increase its roughness. The sandblasting module 2 is fixed on the mounting frame 10 in the sandblasting room. This structural design allows the position and angle of the sandblasting module to be precisely controlled, which is convenient for maintenance and adjustment. The nozzles of each sandblasting module 2 are staggered in the length direction of the metal wire 3, avoiding mutual interference and collision of the airflows ejected by different sandblasting modules, ensuring the stability of the sandblasting process and the uniformity of the wire surface treatment.

[0035] The sand blasting room 1 is also provided with a sand recovery assembly, which is used to suck the sand deposited at the bottom of the sand blasting room 1 back into the sand hopper of the pressurized dry sand blasting machine. The sand recovery assembly includes a suction pipe 6, a pump 7 connected to the suction pipe 6, and a plurality of delivery pipelines 8 connected to the pump 7, and the plurality of delivery pipelines 8 are respectively connected to the sand hopper of the sand blasting module 2. A section of the suction pipe 6 is placed at the bottom of the sand blasting room 1, and the suction pipe 6 is provided with a plurality of suction ports on the bottom section of the sand blasting room 1.

[0036] An industrial camera module 9 is also provided between the sandblasting room 1 and the wire coiler 4. The industrial camera module 9 includes four orthogonally arranged industrial cameras, so as to obtain sample photos of the metal wire 3 at four angles for sample detection.

[0037] Utilization: By recovering the sand material deposited at the bottom of the sandblasting room 1, the recycling of abrasive is achieved, which not only reduces material waste but also reduces production costs. The setting of the suction pipe 6 allows the deposited sand material to be sucked back from the bottom of the sandblasting room 1. The multiple suction ports of the suction pipe 6 are evenly distributed at the bottom of the sandblasting room, ensuring the effective recovery of the sand material. The pump 7 connected to the suction pipe 6 is responsible for generating sufficient suction to suck the sand material in the suction pipe and transport it to the next link. The pump 7 transports the sucked sand material to the sand hopper of each sandblasting module 2 through the delivery pipeline 8. This design allows the sand material to be efficiently distributed and reused between the sandblasting modules. The other end of the delivery pipeline 8 is connected to the sand hopper of the sandblasting module 2, where the sand material is collected and reused in the sandblasting process, ensuring the continuity and stability of the sandblasting operation. The automated design of the entire sand recovery assembly reduces manual intervention and improves the efficiency and reliability of the sandblasting operation. By recycling and reusing sand material, the impact on the environment is reduced, which meets the environmental protection requirements in modern industrial production.

[0038] The sandblasting module 2 in the utility model, i.e., the push-in dry sandblasting machine, is a prior art, and the specific details are not repeated here. The push-in dry sandblasting machine is mainly composed of a sand bucket, a spray gun, an air gun, a sand outlet valve, an air outlet valve, an air source, etc. The air outlet valve is arranged on the air gun, and the sand outlet valve is arranged on the sand outlet pipeline below the sand bucket. The end of the air gun is connected to the sand outlet pipeline, and the air flow mixed with sand is finally sprayed out by the nozzle. The pressure in the pipeline is controlled to ensure the intensity of the sandblasting. The greater the pressure value, the higher the speed of the jet flow, the higher the sandblasting efficiency, and the rougher the surface of the workpiece. Conversely, the surface is relatively smooth. The sandblasting time and the blowing time can be controlled by adjusting the connection time of the sand outlet valve and the air outlet valve to ensure the effect of the sandblasting treatment. The sandblasting time and the blowing time can be set on the touch screen.

[0039] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
