Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pin welding, in particular to an auxiliary tool for pin welding. BACKGROUND

[0002] In the manufacturing process of metal-based copper-clad plate (i.e. aluminum substrate), it needs to go through dozens of strict processes from components to final products. In order to ensure the performance, reliability and high yield of products, each process step needs to have strict requirements and corresponding auxiliary tools. Especially in the process of welding pins on aluminum substrate, since the number of pins is large and the aluminum substrate itself cannot be drilled and positioned, it brings many challenges to the welding process. Although there are some methods of welding pins on the market at present, most of them rely on manual operation, which is difficult to ensure the perpendicularity and parallelism of the pins, and thus affects the welding quality and production efficiency.

[0003] The existing solutions mainly include manual welding and the use of simple clamps. Although manual welding is flexible, it is complex to operate and prone to problems such as pin inclination and skew, which leads to unstable welding quality. Although the simple clamp can partially fix the pins, it still cannot effectively ensure the perpendicularity and parallelism of the pins due to the lack of precise positioning function, especially in mass production, these problems are more prominent.

[0004] The main problem existing in the prior art is that the existing welding methods and clamps cannot effectively ensure the perpendicularity and parallelism of the pins on the aluminum substrate, which leads to unstable welding quality and affects the production efficiency.

[0005] Therefore, based on the above problems, the prior art needs to be improved. CONTENT OF THE INVENTION

[0006] The purpose of the present application is to provide an auxiliary tool for pin welding.

[0007] The above technical purpose of the present application is realized by the following technical scheme: an auxiliary tool for pin welding, comprising a base plate for receiving a workpiece, the base plate is further provided with a mounting positioning plate, the mounting positioning plate is provided with a plurality of positioning holes for mounting pins, the positioning holes correspond to the pads of the workpiece, and the mounting positioning plate is provided with a pressing plate away from the workpiece, so that the part of the pins exposed from the positioning holes is on the same horizontal plane.

[0008] By adopting the technical scheme, the positioning hole on the mounting positioning plate is accurately corresponding to the workpiece pad, and the inner wall of the positioning hole is tightly fitted with the pin, thereby effectively limiting the movement freedom of the pin, ensuring that the pin is perpendicular to the plane of the mounting positioning plate, greatly improving the positioning accuracy and perpendicularity of the pin, and laying a solid foundation for high-quality welding. The guarantee of the perpendicularity enables the pin to form an ideal vertical contact with the pad during welding, which helps the uniform distribution of the welding material and further improves the welding quality. The setting of the pressing plate ensures that the exposed part of the pin is in the same horizontal plane, thereby ensuring the parallelism of the pin and enabling the pin to be uniformly stressed during welding, which significantly improves the welding quality, effectively reduces welding defects such as virtual welding and short circuit, and enhances the electrical connection reliability of the product. The close cooperation of the components not only enables accurate positioning of the pin, stable fixation, and guarantee of perpendicularity and parallelism, but also adapts to automatic welding equipment, greatly improves production efficiency, and meets the needs of industrial large-scale production. At the same time, the electronic components on the workpiece are well protected during the entire operation process, reducing the risk of component damage and effectively improving the overall reliability and yield of the product.

[0009] Optionally, the base plate comprises a main support and a support framework, and a through hole is formed between the main support and the support framework, and a fixing groove is arranged on the main support for embedding and mounting the workpiece.

[0010] By adopting the technical scheme, the combination of the main support and the support framework forms a stable base plate structure, and the through hole formed between the main support and the support framework not only ensures the strength of the base plate but also has the advantage of reducing the overall weight, which facilitates the handling and operation of the tooling, and the through hole also provides a convenient passage for the workpiece to separate from the fixing groove. After welding is completed, the operator can more easily apply external force through the through hole to smoothly separate the workpiece from the fixing groove, thereby improving the convenience of operation and saving the time for disassembling the workpiece. The fixing groove on the main support provides a precise embedding position for the workpiece, effectively preventing the workpiece from moving horizontally during welding, ensuring the stability of the relative position of the workpiece and the mounting positioning plate and other components, and thereby guaranteeing the accuracy of the welding operation.

[0011] Optionally, a threaded hole is arranged at the bottom of the fixing groove, and a stud is arranged on the workpiece, and the threaded hole is arranged corresponding to the stud.

[0012] By adopting the above technical scheme, the workpiece is more stably installed on the base plate, the threaded connection provides reliable fastening force, effectively prevents displacement of the workpiece during welding due to external force (such as vibration of welding equipment, slight collision during operation, etc.), greatly improves the stability of the position of the workpiece during the welding operation, thereby ensuring that the relative position between the pin and the pad always remains accurate, creating solid conditions for high-quality welding. The threaded connection method is convenient for installation and disassembly, can quickly complete the fixing and removal operation of the workpiece while ensuring the firmness of the connection, improves the assembly efficiency in the production process, reduces the time waste caused by cumbersome tooling operation, and helps to improve the overall production efficiency. Through the precise correspondence of the stud and the threaded hole, the positioning function of the workpiece on the base plate can also be realized, further improving the positioning accuracy of the entire auxiliary tooling, making the pin welding process more accurate and reliable, effectively reducing the probability of welding defects caused by inaccurate positioning of the workpiece, and ultimately improving the quality and yield of the product.

[0013] Optionally, the base plate is provided with an automatic welding equipment track fixing hole.

[0014] By adopting the above technical scheme, the auxiliary tooling and the automatic welding equipment are seamlessly connected, enabling the tooling to be accurately and stably installed on the track of the welding equipment. During welding, the tooling is ensured to remain stable with the precise movement of the track, ensuring the accuracy and consistency of the welding position, thereby significantly improving the welding quality. At the same time, this connection method greatly improves production efficiency, enabling the entire welding process to be automated and continuous, eliminating the need for frequent manual adjustment of tooling position, effectively reducing production time and labor costs.

[0015] Optionally, the installation positioning plate is provided with a positioning pin, and the base plate is provided with a mounting hole.

[0016] By adopting the above technical scheme, the positioning pin and the mounting hole cooperate to realize precise and rapid positioning of the installation positioning plate on the base plate, ensuring that the position of the installation positioning plate is consistent and accurate every time it is installed, greatly improving the repeat positioning accuracy of the entire auxiliary tooling. This not only ensures that the positioning hole on the installation positioning plate and the workpiece pad always have a stable and accurate correspondence, providing a reliable foundation for accurate installation of the pin, but also effectively reduces waste caused by positioning deviation during multiple welding operations, improving the yield of the product.

[0017] Optionally, the installation positioning plate is provided with a spacing column.

[0018] By adopting the above technical scheme, the spacer column enhances the structural strength of the installation positioning plate itself, so that the installation positioning plate can maintain good stability when subjected to various external forces such as the pressure plate pressure, pin insertion force, and thermal stress in the welding process, effectively preventing the installation positioning plate from deforming. This is crucial for maintaining the shape and positional accuracy of the positioning hole, ensuring that the perpendicularity and parallelism of the pins during installation and welding are not affected, thereby ensuring the stability and reliability of the welding quality. At the same time, the reasonable layout of the spacer column also optimizes the space below the installation positioning plate, providing certain avoidance space for other components or elements on the workpiece, avoiding squeezing or interference with these components during operation, further improving the compatibility and adaptability of the entire tool in actual use.

[0019] Optionally, the installation positioning plate is provided with an avoidance slot for avoiding electronic elements on the workpiece.

[0020] By adopting the above technical scheme, the risk of squeezing, colliding, or damaging the electronic elements on the workpiece during the connection of the installation positioning plate and the base plate and the pressing of the pressure plate is avoided, effectively protecting the integrity and functionality of the electronic elements and ensuring that the electrical performance of the workpiece as a whole is not affected. This not only improves the one-time qualification rate of the product, reduces the scrap rate caused by damage to the electronic elements, and reduces production costs, but also improves the stability and reliability of the production process.

[0021] Optionally, the pressure plate is provided with a positioning support column.

[0022] By adopting the above technical scheme, the positioning support column ensures the accurate position of the pressure plate on the installation positioning plate, so that the pressure plate can more stably cover above the installation positioning plate, thereby exerting uniform pressure on the pins and ensuring that the part of the pins exposed from the positioning hole is always on the same horizontal plane, further improving the parallelism of the pins. At the same time, the positioning support column also helps to prevent the pressure plate from shifting or shaking during operation, ensuring the stability and reliability of the entire tool during welding. This precise pressure control and stable structural design greatly improves the welding quality and reduces welding defects such as virtual welding and short circuit caused by inaccurate pressure plate position.

[0023] In summary, the present application at least contains the following beneficial effects:

[0024] 1. The positioning hole on the installation positioning plate accurately corresponds to the workpiece pad, ensuring accurate pin installation position and ensuring the perpendicularity of the pins. The inner wall of the positioning hole closely fits the pins, limiting their freedom of movement, making the pins perpendicular to the installation positioning plate plane, laying a foundation for high-quality welding.

[0025] 2. The pressing plate makes the part of the pin exposed to the positioning hole in the same horizontal plane, ensures the parallelism of the pin, and the pin is evenly stressed during welding, which significantly improves the welding quality, reduces welding defects such as false welding and short circuit, and enhances the electrical connection reliability of the product.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] Example 1

[0035] In this embodiment, with reference to Figures 1-5 An auxiliary tool for pin 5 welding includes a base plate 1, an installation positioning plate 3, and a pressing plate 6. The base plate 1 is used to support the workpiece 2. The installation positioning plate 3 is provided with a plurality of pin 5 positioning holes 4 for installing the pin 5. The pin 5 positioning holes 4 are arranged corresponding to the pads of the workpiece 2. The side of the installation positioning plate 3 away from the workpiece 2 is provided with the pressing plate 6. The part of the pin 5 exposed to the pin 5 positioning hole 4 is made to be in the same horizontal plane by the pressing plate 6, so as to ensure the perpendicularity and parallelism of the pin 5.

[0036] Specifically, with reference to Figure 3, the base plate 1 comprises a main support 101 and a support skeleton 102, a through hole 7 is formed between the main support 101 and the support skeleton 102, a fixing groove 8 is arranged on the main support 101, and the workpiece 2 is embedded and installed. The groove bottom of the fixing groove 8 is provided with a threaded hole 9, the workpiece 2 is provided with a stud 10, and the threaded hole 9 is arranged correspondingly to the stud 10. The base plate 1 is also provided with an automatic welding equipment track fixing hole 11, so that the entire auxiliary tooling can be fixed on the track of the automatic welding equipment, realizing automatic welding.

[0037] Referring to Figure 4 , the mounting positioning plate 3 is provided with a positioning pin 12, and the base plate 1 is provided with a mounting hole 13. Through the cooperation of the positioning pin 12 and the mounting hole 13, the precise positioning of the mounting positioning plate 3 and the base plate 1 can be realized. The mounting positioning plate 3 is also provided with a spacing column 14 for maintaining a proper distance between the mounting positioning plate 3 and the workpiece 2, so as to avoid damage to the workpiece 2 during welding. In addition, the mounting positioning plate 3 is provided with a avoiding groove 15 for avoiding the electronic components on the workpiece 2, so as to prevent damage to the electronic components during welding. The mounting positioning plate 3 is also provided with at least one group of pin 5 positioning holes 4, which penetrate the mounting positioning plate 3 and correspond one-to-one to the positions of the pins 5 on the aluminum substrate.

[0038] Referring to Figure 5 , the pressing plate 6 is provided with a positioning support column 16, which fixes the pressing plate 6 on the mounting positioning plate 3, ensuring that the pressure of the pressing plate 6 on the pins 5 is evenly distributed, so that the pins 5 remain in the same horizontal plane, further improving the welding quality.

[0039] The implementation principle of the embodiment is that through the fixing groove 8 and the threaded hole 9 of the base plate 1, the workpiece 2 can be firmly fixed on the base plate 1, avoiding movement of the workpiece 2 during welding. The pin 5 positioning hole 4 and the positioning pin 12 on the mounting positioning plate 3 ensure the accurate position of the pin 5, and the pressing plate 6 keeps the pins 5 in the same horizontal plane through the action of the positioning support column 16, thereby ensuring the perpendicularity and parallelism of the pins 5. This structure design not only improves the welding quality, but also realizes automatic welding, significantly improving the production efficiency.

[0040] Embodiment 2

[0041] The difference between this embodiment and the above-mentioned embodiments is that the structure of the base plate 1 is optimized. Specifically, the main support 101 of the base plate 1 is made of aluminum alloy material, which has good heat conductivity and lightweight characteristics, helping to dissipate heat and reduce the influence of heat on the workpiece 2 during welding. The support skeleton 102 is made of high-strength stainless steel material, which increases the rigidity and stability of the base plate 1, making it less likely to deform under a large pressure.

[0042] Additionally, the design of the fixing groove 8 has also been improved. The inner wall of the fixing groove 8 is equipped with anti-slip rubber pads, enhancing the friction between the workpiece 2 and the base plate 1, and further improving the fixing effect of the workpiece 2. The diameter and depth of the threaded hole 9 have also been optimized to ensure the tight fit between the stud 10 and the threaded hole 9, preventing loosening.

[0043] A cooling channel is added to the mounting positioning plate 3. Through an external cooling liquid circulation system, heat can be removed in a timely manner during the welding process, further improving the welding quality. The arrangement of the cooling channel can be adjusted according to the actual size and shape of the workpiece 2 to adapt to different welding requirements.

[0044] The implementation principle of this embodiment is: by optimizing the material selection and structural design of the base plate 1, the thermal conductivity and rigidity of the base plate 1 are improved, the heat accumulation during the welding process is reduced, and the thermal deformation of the workpiece 2 is prevented. The anti-slip rubber pads in the fixing groove 8 and the optimized design of the threaded hole 9 further enhance the fixing effect of the workpiece 2, ensuring the stability during the welding process. The cooling channel design on the mounting positioning plate 3 effectively controls the temperature of the welding area, improving the welding quality. These improvements not only solve the problems in the prior art, but also further improve the reliability and production efficiency of welding.

[0045] Embodiment 3

[0046] The difference between this embodiment and the above-mentioned embodiments is that the structure of the pressing plate 6 is optimized. Specifically, the pressing plate 6 adopts a segmented design, composed of multiple small pressing plates 6, each fixed on the mounting positioning plate 3 by an independent positioning support column 16. This design can better adapt to different lengths and shapes of the pins 5, ensuring that each pin 5 receives uniform pressure, thereby ensuring the perpendicularity and parallelism of the pins 5.

[0047] In addition, a buffer pad layer is added to the pressing plate 6. The buffer pad layer can be made of soft materials such as silicone or polyurethane foam, which has good elasticity and wear resistance. The role of the buffer pad layer is to absorb a certain impact force when the pressing plate 6 contacts the pins 5, reducing damage to the pins 5 and prolonging the service life of the pins 5.

[0048] The implementation principle of this embodiment is: through the segmented design of the pressing plate 6, it can more flexibly adapt to different lengths and shapes of the pins 5, ensuring that each pin 5 receives uniform pressure, thereby ensuring the perpendicularity and parallelism of the pins 5. The addition of the buffer pad layer not only absorbs a certain impact force and reduces damage to the pins 5, but also improves the stability during the welding process, further improving the welding quality. These improvements not only solve the problems in the prior art, but also further improve the reliability and production efficiency of welding.

[0049] Embodiment 4

[0050] The difference between this embodiment and the above-mentioned embodiments is that the structure of the base plate 1 is further optimized and designed. Specifically, a vibration elimination device is added to the base plate 1, which can effectively reduce the vibration generated during welding and prevent the influence of vibration on the welding quality. The vibration elimination device can adopt the form of a spring damper, which can absorb the vibration energy during welding through the synergistic effect of the spring and the damper, and reduce the amplitude of vibration transmitted to the workpiece 2.

[0051] In addition, a dust suction device is added to the base plate 1, which can timely remove the smoke and particulate matter generated during welding, improve the welding environment, and protect the health of the operator. The dust suction device can adopt a high-efficiency filtration system to ensure that the discharged air is clean and pollution-free.

[0052] The implementation principle of this embodiment is that the vibration elimination device can effectively reduce the vibration generated during welding, prevent the influence of vibration on the welding quality, and improve the stability and reliability of welding. The addition of the dust suction device can timely remove the smoke and particulate matter generated during welding, improve the welding environment, protect the health of the operator, and further improve the safety and environmental protection of welding. These improvement measures not only solve the problems in the prior art, but also further improve the welding quality and production efficiency.

[0053] The embodiments of the specific embodiments are the preferred embodiments of the present application, but do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
