Description

Technical Field

[0001] This invention relates to the field of electronic and electrical welding technology, and in particular to a terminal welding device. Background Technology

[0002] Terminal blocks, as an indispensable basic connecting component in the fields of electronics, electrical engineering, communications, and industrial automation, undertake the core functions of circuit signal transmission and power conduction. The welding quality of their terminals directly determines the operational reliability and service life of terminal equipment. With the accelerated pace of product iteration in downstream industries, the specifications and types of terminal blocks are becoming increasingly diverse, and the production mode is gradually shifting towards multi-variety, small-batch production. This places higher demands on the versatility of welding equipment, production efficiency, and finished product quality.

[0003] Currently, most terminal block welding equipment widely used in the industry is specially designed and can only be adapted to specific specifications and models of terminal products. When production tasks are switched, a lot of debugging work is required on the equipment, and sometimes the welding molds and clamping mechanisms may even need to be replaced entirely. This is not only time-consuming and labor-intensive, but also requires professional technicians to operate, which significantly increases the cost of production switching and the difficulty of equipment maintenance. At the same time, traditional equipment is mostly fixed installation structure, which cannot flexibly adapt to different production scenarios such as workshop assembly lines and on-site operations, thus greatly limiting its application scope.

[0004] Regarding workpiece clamping, existing equipment generally uses rigid clamping mechanisms, which can only position and fix workpieces of fixed dimensions. For irregularly shaped or variable-diameter terminals, insufficient clamping force can lead to workpiece displacement, or excessive clamping force can damage the workpiece surface. In addition, the docking accuracy of the upper and lower welding molds is difficult to guarantee, and misalignment can easily occur during mold closing, leading to welding position deviations and defects such as incomplete welds and off-center welds, affecting the consistency of welding quality.

[0005] In terms of welding process, traditional soldering technology mostly uses single-sided welding or reciprocating scanning and rotating welding with a welding torch. The welding efficiency is low, and it is difficult to control the uniform distribution of solder, which can easily lead to problems such as missed soldering and solder accumulation. More importantly, the joints formed by traditional welding have a simple internal structure and limited tensile and torsional strength. They are prone to cracking and failure under harsh conditions such as vibration and high temperature, which poses safety hazards.

[0006] Cooling is also a crucial factor affecting welding quality. Most existing equipment relies on natural cooling, which is slow and uneven, leading to residual stress in the weld joint and causing weld deformation, cracking, and a low yield. Equipment equipped with cooling systems often uses an integrated cooling structure, which cannot achieve independent, synchronous cooling at each welding station. This results in significant differences in cooling effects between different stations, making it difficult to guarantee consistent quality in mass production.

[0007] In summary, existing terminal block welding equipment has significant shortcomings in terms of versatility, clamping adaptability, welding efficiency, and quality control, and cannot meet the actual needs of current industry development. There is an urgent need to develop a new type of welding equipment that can comprehensively solve the above problems. Summary of the Invention

Both ends of the synchronous water supply pipes and synchronous water outlet pipes extend out of the synchronous position plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] I. Modular design enables adaptation to multiple scenarios and production scales.

[0026] Flexible and adjustable production capacity: Based on the production scale of terminal block welding, the corresponding length of guide mounting posts and the corresponding number of terminal block welding modules can be freely selected, and the number of welding stations of the equipment can be quickly adjusted to adapt to different needs of small-batch customized production and large-batch assembly line production.

[0027] Universal installation scenarios: With the fixed mounting plate and equally angled mounting holes, the equipment can be installed on an external fixed frame or mobile work equipment to meet the requirements of various welding scenarios such as fixed welding in the workshop and on-site operation.

[0028] Welding process adaptive adjustment: The synchronous deflection drive can adjust the overall tilt angle of the equipment in real time to adapt to the process requirements of different welding stages such as welding liquid dripping and guiding, and optimize the flow effect of welding liquid; the drive telescopic column, together with the directional telescopic column, can accurately adjust the opening and closing distance of the upper and lower molds, which facilitates the picking and placing of components to be welded, and the directional telescopic column ensures the stability of the force during the telescopic process and avoids mold misalignment.

[0029] II. Dual-end adaptive clamping structure, balancing clamping stability and workpiece versatility.

[0030] Full-circumference multi-point fixation: The double-end co-fixation of the reset clamping structure and the covering clamping structure is used to clamp both ends of the terminal to be welded, so as to avoid the workpiece displacement during the welding process and ensure the welding position accuracy.

[0031] Adaptive to different workpieces: The reset clamping structure can adaptively fit the end face of workpieces with different diameters through the linkage rotation of the reset swing arm and the rotating clamping arc panel, and the anti-slip texture further enhances the clamping friction; The covering clamping structure can cover the end of workpieces with different shapes and sizes through the elastic deformation of the variable diameter covering telescopic sleeve and the spherical telescopic sleeve, and the arc-shaped anti-slip strip enhances the axial anti-slip capability, realizing stable clamping of irregular and variable diameter terminals without damaging the workpiece surface.

[0032] High mold docking precision: The upper and lower welding molds achieve precise docking through the interlocking of the positioning guide groove and the positioning guide strip, avoiding welding deviations caused by mold misalignment and improving welding consistency.

[0033] III. The spiral frame welding process significantly improves welding efficiency and joint strength.

[0034] Significantly improved welding efficiency: Through the cooperation of the tangential guide tube and the spiral guide groove, the frame welding rod forms a spiral skeleton structure around the component to be welded; the molten welding liquid utilizes the capillary adsorption between the spiral skeleton and the workpiece to rapidly spread from a single drop position and completely cover the entire welding area, realizing "single drop liquid, full circumference welding", eliminating the need for the reciprocating scanning or rotating welding process of traditional welding, and improving welding efficiency by 3-5 times.

[0035] The strength of the welded joint is greatly enhanced: during the welding process, the spiral frame welding rod partially melts with the molten welding liquid and fills the welding gap; the part that is not completely melted acts as a "reinforcing rib" inside the welded joint, forming a composite structure similar to reinforced concrete, which significantly improves the tensile and torsional strength of the welded joint and solves the problems of insufficient strength and easy breakage of traditional tin-welded joints.

[0036] Uniform and controllable welding quality: The uniform distribution of the spiral skeleton ensures uniform flow of the welding fluid, avoiding defects such as incomplete welding, missed welding, and solder accumulation that are common in traditional welding, and significantly improving the welding qualification rate.

[0037] IV. Integrated mold cooling system ensures consistent finished product quality.

[0038] Synchronous and precise cooling: Each terminal welding module is equipped with an independent arc-shaped heat exchange chamber, which is connected to the external circulating cooling system through synchronous water supply pipes, synchronous water outlet pipes and telescopic conduits to achieve synchronous cooling of the mold at all workstations, resulting in high cooling efficiency and consistent cooling effect at each workstation.

[0039] Avoiding cooling stress defects: After welding, the heat of the mold and workpiece is removed in time, so that the weld joint cools down evenly and slowly. This effectively avoids problems such as workpiece cracking, deformation, and weld cracking caused by uncontrollable stress release in traditional natural cooling. It ensures the consistency of dimensional accuracy, appearance quality and mechanical properties of the welded product and greatly reduces the scrap rate.

[0040] V. Quick disassembly and assembly design reduces equipment maintenance and changeover costs.

[0041] Quick replacement of welding modules: The terminal welding modules achieve quick positioning through the plug-in cooperation of the guide mounting cylinder and the guide mounting post. Fixing or disassembly can be completed by simply turning the locking stud. Replacing a single module takes only a few seconds, which greatly improves equipment maintenance efficiency and production changeover speed.

[0042] Automatic cooling pipe connection: The telescopic conduit can automatically connect with the inlet and outlet water connection pipes of the corresponding welding module as the synchronous position plate extends and retracts, eliminating the need for manual connection of each pipe, simplifying the equipment assembly process and reducing the difficulty of operation.

Detailed Implementation

[0056] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0057] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0058] Example 1, please refer to Figures 1-4 In this embodiment of the invention, a terminal welding device includes:

[0059] The combined loading adjustment mechanism includes two synchronous adjustment installation modules facing each other. Each synchronous adjustment installation module includes an adjustment installation plate 1. Synchronous displacement plates 2 are symmetrically arranged on the upper and lower sides of the adjustment installation plate 1. The adjustment installation plate 1 and synchronous displacement plates 2 on the two synchronous adjustment modules are facing each other, and a number of guide installation columns 11 are arranged between the facing synchronous displacement plates 2.

[0060] On the side of the synchronous positioning plate 2 facing the guide mounting column 11, a compression fixing sleeve 14 is provided to cooperate with the guide mounting column 11. The upper and lower sides of the adjusting mounting plate 1 are connected to the synchronous positioning plate 2 facing it, and a drive telescopic column 15 is provided. On both sides of the drive telescopic column 15, a directional telescopic column 16 is symmetrically provided. The two ends of the directional telescopic column 16 are respectively connected to the adjusting mounting plate 1 and the synchronous positioning plate 2 facing it.

[0061] Both adjusting mounting plates 1 are provided with a synchronous deflection drive 3 at the middle position on the opposite side. The outer end of the synchronous deflection drive 3 is provided with a fixed mounting plate 4. The fixed mounting plate 4 is provided with several fixed mounting holes 20 at equal angles.

[0062] And several terminal welding modules that are equally spaced between the opposing adjustment mounting plates 1.

[0063] According to the scale of terminal welding, select the guide mounting post 11 of the corresponding length and the corresponding number of terminal welding modules. First, install the terminal welding modules on the guide mounting post 11, and with the cooperation of the compression fixing sleeve 14, fix the adjusting mounting plate 1 at both ends of the guide mounting post 11 to complete the installation of the synchronous adjusting mounting modules at both ends. At this time, install the fixing mounting plate 4 on the external frame or mobile equipment through the fixing mounting hole 20 to adapt to different welding scenarios.

[0064] The distance between the synchronous displacement plate 2 and the adjustment mounting plate 1 is adjusted by driving the telescopic column 15, which facilitates the placement and removal of the terminal components to be welded. The directional telescopic column 16 can ensure the stability of the force during the telescopic adjustment process. At the same time, the synchronous deflection drive 3 can adjust the tilt angle of the equipment to adapt to the requirements of different welding stages.

[0065] Example 2, based on Example 1, please refer to... Figures 5-9 and Figure 11 In this embodiment of the invention, the terminal welding module includes an upper welding mold 8 and a lower welding mold 9 arranged opposite each other. One end of the upper welding mold 8 and the lower welding mold 9 is symmetrically provided with a reset clamping structure, and the other end of the upper welding mold 8 and the lower welding mold 9 is provided with a covering clamping structure. It also includes a spiral frame forming structure.

[0066] Both the upper welding mold 8 and the lower welding mold 9 are provided with a combined mounting plate 10 at their outer ends. A guide mounting cylinder 21 is provided through the combined mounting plate 10 in conjunction with the guide mounting column 11. A locking stud 22 is provided on one side of the combined mounting plate 10 in conjunction with the guide mounting cylinder 21. During assembly, the guide mounting column 11 is inserted into the guide mounting cylinder 21 for guidance and installation. After reaching the target position, the locking stud 22 is screwed to complete the fixation. Disassembly is done by reversing the operation, which greatly improves the efficiency of disassembly.

[0067] The spiral frame forming structure includes spiral wire grooves 36 provided on the inner walls of the upper welding mold 8 and the lower welding mold 9. One end of the spiral wire groove 36 is fitted with a tangential wire cylinder 23 on the upper welding mold 8. The tangential wire cylinder 23 extends out of the upper welding mold 8, and a tapered wire cylinder 29 is provided at its outer end. A frame welding strip 33, which is a solder bar, is provided in conjunction with the spiral wire groove 36, the tangential wire cylinder 23, and the tapered wire cylinder 29. Two sets of drive wire wheels 32 are positioned opposite each other at the outer end of the tapered wire cylinder 29. Each drive wire wheel 32 has... A drive swing arm 31 is rotatably provided. The outer ends of the drive swing arm 31 are connected to the outer wall of the tapered wire tube 29 through a swing drive component 30. A cutting drive component 34 is semi-embedded at the end of the tapered wire tube 29. A rotating cutting tool 35 is provided at the outer end of the cutting drive component 34. A positioning guide groove 37 is symmetrically provided on the lower end face of the upper welding mold 8. A positioning guide strip 39 is provided on the upper end face of the lower welding mold 9 in conjunction with the positioning guide groove 37. The positioning guide strip 39 and the positioning guide groove 37 cooperate to significantly improve the docking accuracy of the upper welding mold 8 and the lower welding mold 9.

[0068] The reset clamping structure includes two sets of reset swing arms 25 arranged in pairs. One end of each set of reset swing arms 25 is provided with a rotating clamping arc panel 27 via a connecting shaft 26. The inner side of the rotating clamping arc panel 27 is provided with anti-slip texture 28. The other ends of the two sets of reset swing arms 25 are respectively installed on one end of the upper welding mold 8 and the lower welding mold 9 via a reset shaft 24.

[0069] The encapsulation and clamping structure includes two spherical telescopic sleeves 12 arranged in pairs at the other end of the upper welding mold 8 and the lower welding mold 9. The outer ends of the two spherical telescopic sleeves 12 are provided with variable diameter encapsulation telescopic sleeves 13, and the inner side of the outer end of the variable diameter encapsulation telescopic sleeves 13 is provided with several arc-shaped anti-slip strips 38.

[0070] As the telescopic column 15 extends and retracts, the spacing between the synchronous positioning plate 2 and its upper guide mounting column 11 adjusts accordingly. This adjusts the spacing between the upper welding mold 8 and the lower welding mold 9 mounted on the guide mounting column 11, allowing for the opening and closing of the upper and lower welding molds. This facilitates the placement and removal of the terminal components to be welded. When the upper and lower welding molds 8 and 9 are open, the terminal components to be welded are placed inside, and then the upper and lower welding molds 8 and 9 are joined together. During this process, the rotating clamping arc panel 27 contacts the welding component at one end, causing the two ends of the reset swing arm 25 to rotate around the reset shaft 24 and the connecting shaft 26, respectively. Under the action of the reset shaft 24... The force of reverse rotation provided to the reset swing arm 25 causes the rotating clamping arc panel 27 to deform. Under the action of the connecting shaft 26, the rotating clamping arc panel 27 is made to fit against the welding element. With the anti-slip texture 28 on it, the stability of the clamping and fixing is ensured. At the same time, the variable diameter covering telescopic sleeve 13 first contacts the welding element at the other end. As the distance between the upper welding mold 8 and the lower welding mold 9 decreases, the deformation of the variable diameter covering telescopic sleeve 13 intensifies, causing the spherical telescopic sleeve 12 to also deform until the upper welding mold 8 and the lower welding mold 9 are connected, so that the variable diameter covering telescopic sleeve 13 and the spherical telescopic sleeve 12 fit against the welding element. At this time, the fixing of the welding element at the other end is completed.

[0071] Subsequently, the external servo wire feeding mechanism introduces the frame welding strip 33 into the tapered wire guide cylinder 29. Under the clamping and guiding of the two drive wire guide wheels 32, the frame welding strip 33 is continuously introduced into the tangential wire guide cylinder 23. The frame welding strip 33 is then introduced from the tangential wire guide cylinder 23 into the spiral wire guide groove 36, and after being introduced along the spiral wire guide groove 36 at a certain interval, it forms a spiral shape around the component to be welded inside. The cutting drive 34 is activated, causing the rotating cutting tool 35 to cut the frame welding strip 33. At this time, the external equipment drips a preset amount of molten welding liquid from one end of the reset clamping structure into the mating upper welding mold 8 and lower welding mold 9. Due to the spiral... A capillary adsorption structure is formed between the spiral frame welding rod 33 and the component to be welded. The molten welding liquid is rapidly guided along the spiral frame welding rod 33, completely covering the welding area and completing the welding operation. This process can also change the tilt angle of the equipment by driving the synchronous deflection drive 3, which facilitates the dripping of welding liquid and improves the guiding efficiency and quality of welding liquid. Traditional welding can only weld one side, or use a reciprocating or rotary welding process, which is inefficient and of poor quality. This equipment can achieve single-point full-coverage welding, and the spiral frame welding rod 33 can melt with the molten welding liquid, increasing the single welding surface. The unmelted part acts as an internal frame structure similar to steel bars, which improves the welding strength.

[0072] Example 3, based on Example 2, please refer to... Figure 10 and Figure 11 In this embodiment of the invention, both the upper welding mold 8 and the lower welding mold 9 are provided with arc-shaped heat exchange chambers 40 inside their cylinder walls. C-shaped guide tubes 17 are symmetrically arranged at both ends of the arc-shaped heat exchange chambers 40. The C-shaped guide tubes 17 at both ends are respectively provided with inlet connecting pipes 18 and outlet connecting pipes 19. Synchronous water supply pipes 5 and synchronous water outlet pipes 7 are symmetrically arranged at both ends of the synchronous position plate 2. The synchronous water supply pipes 5 and synchronous water outlet pipes 7 are each provided with a number of telescopic guide tubes 6 corresponding to the number of terminal welding modules. The telescopic guide tubes 6 are connected to the corresponding inlet connecting pipes 18 and outlet connecting pipes 19. Both ends of the synchronous water supply pipes 5 and synchronous water outlet pipes 7 extend out of the synchronous position plate 2.

[0073] After the terminal welding module is installed, the telescopic conduit 6 is connected to the corresponding inlet connection pipe 18 and outlet connection pipe 19. The synchronous water supply pipe 5 and synchronous water outlet pipe 7 are connected to the external main water supply equipment and main pumping equipment. Cold water enters from the synchronous water supply pipe 5, enters the inlet connection pipe 18 through each telescopic conduit 6, enters from one end of the arc heat exchange chamber 40 through the C-shaped guide tube 17, and then exits from the other end of the C-shaped guide tube 17. It is then introduced into the synchronous outlet pipe 7 through the outlet connection pipe 19 and the telescopic conduit 6 to dissipate heat in time for the upper welding mold 8 and the lower welding mold 9, realizes mold cooling, ensures the uniformity of the quality and appearance after welding, avoids cracking or even breakage caused by uncontrollable stress release during conventional cooling, and improves the quality of welding.
