Description

Technical Field

[0001] The utility model belongs to the technical field of chip welding, and in particular relates to a positioning fixture for chip welding. Background Art

[0002] Traditional chip welding positioning methods often rely on workers' experience and manual operations, and there are problems such as inaccurate positioning, low efficiency, and human factors affecting quality stability. In order to solve these problems, welding positioning jigs have gradually become an important auxiliary tool in the welding process in recent years. Welding positioning jigs can help workers accurately position and fix workpieces during the welding process through precise positioning and support functions, thereby improving the accuracy and consistency of welded joints and reducing the impact of human factors on welding quality. At the same time, welding positioning jigs can also improve welding production efficiency, reduce labor intensity, and improve work safety.

[0003] Although there are many types of welding positioning jigs on the market, there are still some challenges and room for improvement. Some traditional welding positioning jigs usually have the following problems: 1. Complex design, inconvenient adjustment and other problems, which cannot meet the needs of high-efficiency production; 2. Traditional jigs are usually made of materials such as steel, aluminum alloy, plastic or composite materials. There are obvious problems when these materials are used as welding jigs: First, although steel has high strength and hardness, its thermal conductivity is poor, and it is easy to accumulate too much heat during the welding process, resulting in uneven heating and deformation of the welded joint. Secondly, although aluminum alloy has good thermal conductivity and light weight, it may expand and deform in high temperature environments, affecting the accuracy and stability of welding positioning. In addition, although plastic or composite materials can reduce the weight of the jig and avoid damage to the workpiece surface, they have poor high temperature resistance and wear resistance, and are prone to deformation or wear after long-term use, affecting the welding quality and the service life of the jig.

[0004] The purpose of the embodiment of the utility model is to provide a positioning fixture for chip welding, which has a simple design, is easy to adjust, has accurate positioning, and can improve welding quality.

[0005] The utility model embodiment is achieved in this way:

[0006] A positioning fixture for chip welding, comprising: a graphite base and a graphite chip fixture;

[0013] Figure 1 This is a disassembled state diagram of the positioning fixture for chip welding of the utility model; DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] This utility model requires further research and improvement on the design and performance of welding positioning fixtures to improve their accuracy, flexibility and applicability to meet the evolving welding process and production needs. Based on this, a new type of welding positioning fixture is proposed. Through innovative design and optimized performance, the problems existing in existing welding positioning fixtures are solved, welding quality and production efficiency are improved, and the progress and application of welding technology are promoted.

[0016] The utility model adopts graphite as the production material of the jig, and graphite has unique advantages as the production material of the welding positioning jig. First, graphite has excellent thermal conductivity, can effectively absorb and conduct the heat generated during the welding process, thereby helping to maintain the stable temperature of the welding workpiece and the jig and reduce the risk of welding deformation. Secondly, graphite has good wear resistance and corrosion resistance, can withstand the friction and chemical corrosion in the welding process for a long time, and maintain the stability and life of the jig. In addition, graphite has a low thermal expansion coefficient, can maintain shape stability in a high temperature environment, and ensure the accuracy and consistency of welding positioning. Finally, graphite has good processing performance, and can be made into various complex welding positioning jigs through processing and molding to meet the needs of different workpieces and welding processes. In summary, graphite as a production material for welding positioning jigs has multiple advantages such as excellent thermal conductivity, wear resistance and corrosion resistance, high thermal stability and good processing performance, which can effectively improve welding quality, production efficiency and the service life of the jig.

[0017] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments:

[0018] like Figure 1 As shown, a positioning fixture for chip welding includes: a graphite base 1 and a graphite chip fixture 7;

[0019] The graphite base is provided with a lower accommodating cavity 3 for accommodating a substrate 5, and the edge of the substrate is tightly placed in the lower accommodating cavity; the graphite base is provided with an upper accommodating cavity 4 for accommodating a graphite chip fixture, and the edge of the graphite chip fixture is tightly placed in the upper accommodating cavity, and the upper accommodating cavity is located directly above the lower accommodating cavity;

[0020] Grooves 2 are respectively provided on both sides of the graphite base, and the grooves are connected to both the upper accommodating cavity and the lower accommodating cavity;

[0021] A plurality of chip-shaped through holes 6 are arranged on the graphite chip fixture, and the plurality of chip-shaped through holes are sequentially arranged and distributed on the graphite chip fixture; the positions of the chip-shaped through holes correspond to the welding positions of the chips on the substrate.

[0022] In the figure, when the edge of the graphite chip fixture is tightly placed in the upper accommodating cavity, the upper surface of the graphite chip fixture is flush with the upper surface of the graphite base.

[0023] In the figure, the graphite base is in the shape of a rectangular parallelepiped as a whole.

[0024] When in use, the substrate is placed in the lower accommodating cavity of the graphite base, and then the graphite chip fixture is placed in the upper accommodating cavity of the graphite base. Since the edges of the substrate and the graphite chip fixture are closely connected to the inner cavity wall of the accommodating cavity, and the graphite chip fixture tightly adheres to the upper surface of the substrate, the substrate is firmly fixed inside the graphite base without displacement. The chip to be welded is placed through the chip-shaped through hole 6, and the chip welding position on the substrate can be aligned, and then the chip can be welded. After welding, the substrate and the graphite chip fixture are separated from the graphite base through the grooves on both sides of the graphite base, so that the substrate can be quickly removed for the next welding, thereby improving work efficiency and ensuring welding accuracy.

[0025] The specific plan is as follows:

[0026] Base design of substrate: The base is made of graphite material, which has excellent thermal conductivity and wear resistance. The base is reasonably designed to adapt to substrates of different sizes and shapes and provide stable fixed support. By fixing the base, the accurate positioning and stable support of the substrate during the welding process are ensured, and the welding quality and production efficiency are improved. Chip fixture design: The chip fixture is made of graphite material, which has excellent thermal conductivity and wear resistance and corrosion resistance. The fixture design is precise and can ensure the precise alignment between the chip and the substrate. The accuracy and quality stability of the welding joint are guaranteed by the accurate positioning and support of the chip fixture. 3. Manufacturing process and assembly method: Modern processing technology, such as CNC processing, is used to precisely process and shape the graphite material to ensure the geometric size and surface quality of the fixture. Assemble the base and the chip fixture to ensure their stable connection and mutual cooperation to form a complete chip positioning fixture.

[0027] The utility model has the following advantages:

[0028] 1. Improve welding quality: Since the chip positioning fixture is made of graphite material, it has excellent thermal conductivity and stability, can effectively absorb and conduct the heat generated during the welding process, reduce the risk of welding deformation, and thus improve the accuracy and quality stability of the welding joint.

[0029] 2. Increase production efficiency: The fixture has a simple design, is easy to adjust, and has complete functions. It can provide stable fixed support and precise positioning functions, which helps to reduce adjustments and repetitive work during the welding process and improve production efficiency and work efficiency.

[0030] 3. Reduce production costs: Chip positioning jigs made of graphite material have the advantage of low production cost. At the same time, their wear resistance, corrosion resistance and high thermal stability can extend the service life of the jig, reduce replacement and maintenance costs, and thus reduce the overall production cost.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
