[0068] The following is a detailed description of an embodiment of the present invention, a cylindrical small parts welding positioning platform, with reference to the accompanying drawings.
[0069] Reference Figures 1 to 9 As shown, a cylindrical small part welding positioning platform provided according to an embodiment of the present utility model includes a base plate 10, a support plate 20, a storage platform 30, two positioning components 21 and a support platform 32.
[0070] The base plate 10 is suitable for mounting on a workbench.
[0071] The tray 20 is positioned above the base plate 10.
[0072] The platform 30 is disposed on the tray 20 and is used to place the material to be processed. The platform 30 is provided with a suction cup 31 for adsorbing the material to be processed on the platform 30.
[0073] The two positioning members 21 are disposed on the tray 20 and located on opposite sides of the two placing platforms 30, for insertion into the positioning holes 22 of the material to be processed.
[0074] The support platform 32 is disposed on the support plate 20 and is positioned vertically opposite to the welding part of the material to be processed and the cylindrical part, in order to support the welding part of the material to be processed and the cylindrical part.
[0075] Based on the above, the platform 30, equipped with suction cups 31, effectively suppresses material movement caused by thermal stress or mechanical vibration during welding by using negative pressure to adsorb the material to be processed. Combined with the insertion of positioning components 21 into the material positioning holes 22 on both sides, a horizontal dual-point constraint is formed, achieving precise fixation of the material on the support plate 20 and significantly reducing the risk of weld point position deviation. The support platform 32 is positioned vertically opposite to the welding part, providing precise support for complex contours such as motherboard extensions and edge interfaces, overcoming the shortcomings of traditional fixtures in supporting irregular structures. By directly supporting the welding area, the support platform 32 disperses welding stress, avoiding problems such as incomplete welds and weld point breakage, making it particularly suitable for micron-level precision welding scenarios. Through structural innovation, this platform simultaneously solves two major technical bottlenecks in welding small cylindrical parts: offset control and local support, providing an engineering solution for high-precision, high-reliability welding of electronic device motherboards.
[0076] Preferably, in one embodiment of the present invention, both positioning elements 21 include a mounting base 211 and a positioning pin 212.
[0077] The mounting base 211 is detachably mounted on the tray 20. Both sides of the shelf 30 are provided with clearance grooves 33, and the two mounting bases 211 are respectively located in the clearance grooves 33.
[0078] The positioning pin 212 is provided on the mounting base 211 and is used to be inserted into the positioning hole 22 of the material to be processed.
[0079] Thus, the positioning pin 212, inserted into the material positioning hole 22, forms a rigid constraint, creating a dual positioning mechanism with the flexible adsorption of the suction cup 31. The rigid positioning pin 212 effectively resists material deformation caused by welding thermal stress, while the flexible suction cup 31 absorbs mechanical vibration. The synergistic effect of the two significantly reduces the risk of weld point position deviation and improves welding accuracy. Furthermore, the clearance groove 33 allows the positioning pin 212 to be vertically aligned with the positioning hole 22 of the material to be processed.
[0080] Preferably, in one embodiment of the present invention, the support platform 32 includes an installation part 321 and a support part 322.
[0081] The mounting part 321 is detachably mounted on the tray 20.
[0082] The support portion 322 is provided on the upper surface of the mounting portion 321 to fit and support the welded portion of the material to be processed and the cylindrical part.
[0083] Thus, the mounting section 321 adopts a detachable design, allowing for quick replacement of the support section 322 (such as support modules with different curvatures and sizes) based on the size of the cylindrical part, welding position, or motherboard structure. This design enables the same platform to be compatible with welding various specifications of materials, reducing equipment modification costs, and is particularly suitable for flexible production scenarios with multiple varieties and small batches. The support section 322 directly fits the welding area, using surface contact instead of traditional point contact support, effectively dispersing welding stress and avoiding defects such as incomplete welds and weld point breakage. For complex contours such as motherboard extensions and edge interfaces, the support section 322 can be customized into an irregular curved surface to achieve precise matching with the welding part, significantly improving the consistency of welding quality.
[0084] Preferably, in one embodiment of the present invention, the support portion 322 is provided with a through hole 323, which extends to the bottom surface of the support plate 20, so that the auxiliary positioning column on the workbench can be inserted into the cylindrical part through the through hole 323 to fix the cylindrical part.
[0085] Thus, the through hole 323 allows the auxiliary positioning post to be directly inserted into the cylindrical part from the bottom surface of the support plate 20, forming a rigid constraint in the vertical direction. Working in conjunction with the supporting function of the platform 32, it achieves a dual fixing mechanism of "surface contact support + point contact positioning," effectively suppressing part displacement caused by thermal stress or mechanical vibration during welding and significantly improving the positional accuracy of the weld point. The auxiliary positioning post directly engages with the internal structure of the part (such as the axial hole) through the through hole 323, achieving "one-step" positioning. Operators do not need to repeatedly adjust the position of the part to ensure precise alignment with the welding surface of the main board, greatly shortening loading time, and is especially suitable for the rapid changeover requirements in automated production lines.
[0086] Preferably, in one embodiment of the present invention, a plurality of suction cups 31 are provided, and the plurality of suction cups 31 are distributed at intervals on the placement platform.
[0087] Thus, the multiple suction cups 31, spaced apart, form a dispersed adsorption force field, avoiding material deformation (such as bending of thin motherboards) caused by high pressure at a single point. The adsorption force is evenly transmitted to the material surface, which is especially suitable for fixing brittle materials or high-precision components, ensuring the flatness of the material before welding. When a single suction cup 31 fails, the remaining suction cups 31 can still maintain the material basically fixed, avoiding overall displacement due to local adsorption failure. This redundancy mechanism significantly improves the fault tolerance of the welding process, and is especially suitable for automated production lines with long-term continuous production.
[0088] Preferably, in one embodiment of the present invention, each suction cup 31 includes a connecting seat 311 and a cup body 312.
[0089] The upper surface of the shelf 30 is provided with a plurality of mounting holes 34 at intervals, and the lower ends of the plurality of connecting seats 311 are all connected to the mounting holes 34.
[0090] The disc body 312 is located on the upper end of the connecting seat 311, and the disc body 312 is provided with a negative pressure hole.
[0091] The tray 20 has an air passage 23 inside, one end of which extends to the side of the tray 20 and is connected to the negative pressure device. The lower ends of the multiple connecting seats 311 extend into the air passage 23 so that the negative pressure hole and the air passage 23 are connected.
[0092] In this way, the air passage 23 inside the tray 20 connects the negative pressure holes of multiple suction cups 31 in parallel to a single negative pressure device, avoiding the complex pipeline layout of each suction cup 31 being independently connected to an air tube in traditional solutions. This design significantly reduces the difficulty of device assembly, reduces the risk of air tube entanglement, improves system reliability, and reduces the energy consumption of the negative pressure device (shared pump body). Furthermore, the pluggable design of the connector 311 and the mounting hole 34 of the platform 30 allows for independent replacement of individual suction cups 31. When the plate body 312 is worn or the negative pressure hole is blocked, only the corresponding connector 311 needs to be removed for repair, without replacing the entire tray 20 or air passage 23 structure, greatly shortening maintenance time and reducing spare parts inventory pressure.
[0093] Preferably, in one embodiment of the present invention, the upper surface of the tray 20 is provided with a plurality of threaded holes 24, the plurality of threaded holes 24 are arranged opposite to the plurality of mounting holes 34, and the lower ends of the threaded holes 24 all penetrate into the air passage 23.
[0094] Each of the connecting seats 311 has a stud 313 at its lower end. The stud 313 is detachably connected to the threaded hole 24. The negative pressure hole passes through the stud 313 and connects to the air passage 23.
[0095] In this way, the connector can be quickly assembled and disassembled by screwing the stud 313 into the threaded hole 24 of the support plate 20. If a single suction cup 31 is damaged, it can be replaced independently without replacing the entire support plate 20 or air passage 23 structure. This design significantly shortens equipment maintenance time, reduces production downtime caused by adsorption system failures, and improves the overall efficiency of the equipment.
[0096] Preferably, in one embodiment of the present invention, one end of the airway 23 is connected to a connector 25, which is adapted to be connected to a negative pressure device.
[0097] Thus, connector 25 uses standardized interfaces (such as quick-connect or threaded types), enabling "plug-and-play" connection with negative pressure equipment, significantly reducing equipment commissioning time. In automated production lines, this feature supports rapid replacement or maintenance of negative pressure equipment, reducing production downtime caused by pipeline connections and improving overall equipment efficiency.
[0098] Preferably, in one embodiment of the present invention, each of the four corner posts on the upper surface of the base plate 10 is provided with a connecting block 11, and the upper end of each connecting block 11 is connected to the bottom surface of the support plate 20.
[0099] Thus, the connecting block 11, as an independent component, can have its quantity and layout adjusted (e.g., four-corner, hexagonal, or edge-distributed) according to the size of the pallet 20 or load requirements. This modular design allows the same base plate 10 to be compatible with pallets 20 of different specifications and welding platforms, reducing equipment modification costs and improving production line flexibility.
