Description

TECHNICAL FIELD

[0001] The application relates to the field of welding processing devices, and particularly relates to an electronic component cylindrical shell welding processing device. BACKGROUND

[0002] Electronic components are parts of electronic elements and small machines and instruments, which are usually composed of several parts and can be used in similar products, and are usually some parts of electric appliances, radios and instruments, and are the general term of electronic devices such as capacitors, transistors, hairsprings and mainsprings; there are many types of electronic components, and the shapes are not consistent, among which the cylindrical state is relatively common, and generally, the cylindrical electronic components are matched with an outer shell, which can play a protective role and can avoid the internal parts of the electronic components being too scattered, and can also play a certain shielding role. At present, when the cylindrical component shell is processed, manual welding is usually adopted. When welding, a bending machine is used to bend the cut raw material plate into a circular tube and clamp and fix it, and then manual operation is used to weld the connecting part of the bent shell to form the shell. However, the cylindrical shell is prone to springback after bending, so that the joint of the formed cylindrical shell is deviated, and the ordinary bending machine cannot pressurize the formed cylindrical shell. In this case, manual pressing is usually required to align the joint of the cylindrical shell before welding. This processing method reduces the processing efficiency of the cylindrical shell. After welding, the inner and outer walls of the shell need to be polished to keep the inner and outer walls smooth, so manual polishing of the welded shell is required, which further reduces the efficiency of the electronic component cylindrical shell welding processing. To solve the above problems, through retrieval, the Chinese patent with the publication number CN113399894A discloses an electronic component cylindrical shell welding processing device, which comprises a base, the base is in a convex structure, a semicircular structure one-way pressing groove is formed in the top of the base, a one-way sliding groove is symmetrically formed in the top of the base and located on both sides of the one-way pressing groove, a one-way electric sliding block is slidably installed in the one-way sliding groove, a one-way pressing block is arranged above the one-way sliding groove, the bottom of the one-way pressing block is fixedly connected with the corresponding one-way electric sliding block, a second pressing groove is formed on the side of the two one-way pressing blocks close to each other, the second pressing groove is opposite to the one-way pressing groove The device can weld and polish the cylindrical shell, but the circular structure of the cylinder has certain rigidity and stability in actual use; the deformation of the weld is constrained by the overall structure of the cylinder and cannot expand freely, which generates additional stress at the welded joint; when the clamps on both sides of the cylinder are removed, the stress causes the welded joint to expand outward, generating outward tension; when the tension exceeds the strength limit of the weld metal, cracks will occur at the weld, reducing the strength and sealing performance of the welded joint.

[0017] Detailed Implementation Method 1: Please refer to... Figures 1-8This invention provides a technical solution: a welding processing device for cylindrical shells of electronic components, including a worktable 1, four sets of support legs 2 evenly installed on the bottom of the worktable 1, a welding auxiliary processing mechanism 3 installed on the surface of the worktable 1, a bottom support platform 33 installed on the welding auxiliary processing mechanism 3, a device shell 5 covered on the surface of the bottom support platform 33, a side support platform A35 movably installed on the left side of the surface of the bottom support platform 33, a side support platform B350 movably installed on the right side of the surface of the bottom support platform 33, a welding gun 4 installed above the side support platform B350 and the side support platform A35, the welding gun 4 being positioned directly above the seam of the device shell 5; a cylinder 330 is installed at the bottom of the bottom support platform 33, the bottom support platform 33 is driven to rise and fall by the cylinder 330, the bottom of the cylinder 330 is fixedly connected to the middle of the surface of the worktable 1.

[0018] Working Principle: In actual use, the blank is first placed on the upper surface of the bottom support platform 33. The bottom support platform 33 moves upward under the drive of the cylinder 330. Simultaneously, under the drive of the two rows of drive cylinders 353, the side support platforms A35 and B350 move upward. Both sets of annealing seats 36 have slots 30 at their bottoms, and the bottom support platform 33 has slots 30 on its surface. The three sets of slots 30 are combined to form an annular pressing groove. The device housing 5 is snapped onto the outside of the inner support rod 32 and pressed into a cylindrical housing through the annular pressing groove. At this time, under the action of the welding equipment's drive structure, the welding gun 4 moves axially along the joint of the device housing 5 to complete the joint welding work. The welding equipment and its drive structure... The composition is not shown in the drawing; the bottom support platform 33 moves upward under the drive of the cylinder 330, and the two sets of side support platforms move upward under the drive of the drive cylinder 353, so that the three sets of slots 30 can quickly combine into an annular pressing groove, clamping and pressing the device housing 5 into a cylindrical housing. The multi-component collaborative pressing method can achieve efficient and precise positioning and pressing, ensuring the shape and dimensional accuracy of the device housing 5, and providing a good foundation for subsequent welding work; the inner support rod 32, combined with the annular pressing groove, supports and fixes the device housing 5 from both the inner and outer sides, effectively preventing deformation or displacement of the device housing 5 during welding, ensuring the stability and quality of welding; especially for structures like cylindrical housings that require ensuring circumferential shape and joint accuracy, this stable support is crucial. The support structure is particularly important; under the action of the welding equipment drive structure, the welding gun can move axially along the joint of the device housing 5, ensuring the accuracy and consistency of the welding trajectory; when the side support platforms A35 and B350 cover the outside of the device housing 5 and bend the device housing 5, heating coil plates 38 are positioned and installed inside the side support platforms A35 and B350 through positioning strips 39 and positioning grooves 391. The heating coil plates 38 generate high temperature, which can perform high-temperature annealing on the joint position to be welded; by installing the heating coil plates 38 inside the side support platforms A35 and B350 through the positioning strips 39 and positioning grooves 391, it can ensure accurate heating and annealing of the joint between the heating coil plates 38 and the device housing 5. The heating coil plate 38 surrounds the joint of the device housing 5, enabling precise heating of the joint area to be welded, thus improving the accuracy and consistency of the annealing process. This uniform high-temperature annealing effectively eliminates the stress generated during the bending process of the device housing 5, improves the material's microstructure, and enhances its toughness and ductility, creating favorable conditions for subsequent welding work, thus improving welding quality and reducing welding defects. Integrating the heating coil plate 38 inside the side support platform makes the entire device compact and space-efficient. Simultaneous high-temperature annealing can be performed while bending the device housing 5, reducing process steps and equipment footprint, and improving production efficiency.High-temperature annealing allows the atoms inside the device housing 5 to gain sufficient energy for rearrangement, effectively eliminating residual stress generated by bending and placing the device housing 5 in a more stable state. After welding, the interaction between residual stress and welding thermal stress will prevent excessive stress, thus avoiding crack formation. High-temperature annealing can homogenize the microstructure of the device housing 5 material and refine the grain size. After annealing, the toughness and plasticity of the material are improved, while the hardness is reduced. The device housing 5 can better withstand thermal stress and deformation during welding without cracking due to excessive brittleness. The enhanced plastic deformation capacity of the material allows the device housing 5 at the weld joint to relieve stress through its own deformation when subjected to tension, rather than directly cracking. Unannealed device housing 5 joints may have high hardness due to work hardening, which can easily lead to stress concentration during welding and make it difficult to fuse well with the welded device housing 5. High-temperature annealing reduces the material hardness, making heat transfer more uniform during welding, allowing the welded device housing 5 to fuse better with the base material, forming a high-quality weld joint and reducing the risk of cracks due to poor fusion.
