Description

Technical Field

[0001] The invention belongs to the technical field of copper busbar welding machines, relates to a technology for achieving accurate and stable positioning of copper busbars, and particularly relates to a positioning frame for copper busbar welding and a copper busbar welding machine. Background Art

[0002] Copper busbar welding technology is widely used in power systems, electronic equipment, and industrial manufacturing. As a metal material with excellent conductivity, copper busbars are widely used for connections and conductive paths in high-current electrical equipment. However, the copper busbar welding process faces many technical challenges, mainly including the following aspects:

[0003] Typically, two copper bars to be welded need to be spliced ​​together and welded at the seam. Common copper bar splicing methods vary, for example, the longitudinal axes of the two bars are perpendicular to each other, with the end of one bar abutting the side of the other, or vice versa, or the longitudinal axes of the two bars are aligned.

[0004] Regardless of the splicing method used, the copper busbars must be positioned and fixed. In the prior art, the conventional method is to first position the busbars, then fix them. As the copper busbar splicing method changes, the positioning structure needs to be frequently switched between multiple positioning stations. Over time, the positioning structure can easily wear out, resulting in inaccurate positioning, which in turn affects the quality of the copper busbar welding. Summary of the Invention

DETAILED DESCRIPTION

[0091] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0092] See also Figures 1 to 10 As shown, the specific embodiments provided by the present invention are as follows:

[0093] like Figures 8 to 10 As shown, the first embodiment of the present invention provides a positioning frame 1 for copper busbar welding, comprising:

[0094] Rack 1;

[0095] Positioning components are arranged on the table of the frame 1, and two sets of positioning components are located on opposite sides of the welding position of the copper busbar to be welded;

[0096] Wherein, each group of the positioning components comprises at least a first positioning member 7 and a second positioning member 8;

[0097] The first positioning member 7 is fixedly arranged on the table of the frame 1 and has a positioning surface formed along the first direction;

[0098] The second positioning member 8 is formed with an abutting surface 805 facing the positioning surface;

[0099] The distance X between the abutting surface 805 and the positioning surface satisfies:

[0100] X≥L, X≥W;

[0101] L is the length of the copper bar to be welded, and W is the width of the copper bar to be welded;

[0102] The second positioning member 8 can be adjusted to move along the second direction so that the abutting surface 805 moves toward or away from the fixed positioning surface;

[0103] The first direction is a direction perpendicular to the length direction of the welding part of the copper bar to be welded;

[0104] The second direction is perpendicular to the first direction;

[0105] Furthermore, each copper bar to be welded is fixed between the abutting surface 805 and the positioning surface of each set of positioning components.

[0106] In this embodiment, the positioning assembly includes a first positioning member 7 and a second positioning member 8 .

[0107] The first positioning member 7 is fixedly connected to the tabletop of the frame 1. In other words, the position of the positioning surface formed by the first positioning member 7 is fixed. Correspondingly, the second positioning member 8 can be adjusted and displaced along the first direction. This is because the abutment surface 805 formed by the second positioning member 8 secures the copper busbar to be welded between the abutment surface 805 and the positioning surface. When one end face of the copper busbar to be welded abuts the positioning surface, and the other end face abuts the abutment surface 805, the copper busbar to be welded is positioned and fixed.

[0108] Furthermore, when the splicing configuration of the copper busbar to be welded changes, the spacing between the abutment surface 805 and the positioning surface can be adjusted to accommodate such changes. Furthermore, in the initial position, meaning that the second positioning member 8 has not undergone any displacement adjustment, the spacing X between the positioning surface and the abutment surface 805 is greater than both the length L and the width W of the copper busbar to be welded. In this way, regardless of how the splicing configuration of the copper busbar to be welded changes, adjusting the position of the second positioning member 8 ensures that the copper busbar to be welded is completely secured.

[0109] Based on the above, since the thermal conductivity of the copper busbar to be welded is relatively high, in order to prevent it from transferring high heat to the positioning component, the following optimization is further made:

[0110] The tabletop of the rack 1 is formed with a sunken mounting groove 9, and the second positioning member 8 is installed within the mounting groove 9. As a result, the height H1 between the bottom of the mounting groove 9 and the central axis of the second positioning member 8 is less than the height H2 between the bottom of the mounting groove 9 and the copper busbar to be welded. In other words, the second positioning member 8 does not serve as a support. Except for the contact surface 805 that forms contact with the copper busbar to be welded, the rest of the second positioning member 8 does not contact the copper busbar to be welded. This prevents the copper busbar to be welded from transferring high heat to the second positioning member 8, which could cause structural damage to the second positioning member 8 and avoid the problem of reduced positioning accuracy of the second positioning member 8.

[0111] On the basis of the above, the first positioning member 7 includes:

[0112] A calibration piece is arranged on the table of the frame 1, and the setting position of the calibration piece is fixed;

[0113] A positioning plate connected to the frame 1 through the calibration member;

[0114] Wherein, the length direction of the positioning plate is consistent with the first direction;

[0115] Furthermore, the side end surface of the positioning plate facing the copper busbar to be welded constitutes the positioning surface.

[0116] Specifically, the calibration component is a member that determines the installation position of the positioning plate. It is fixed on the tabletop of the rack 1. In other words, regardless of the splicing configuration of the copper busbar to be welded, the mounting position of the positioning plate remains fixed. This ensures that the positioning surface formed by the positioning plate remains fixed, eliminating the need to frequently switch the mounting position to accommodate different splicing configurations of the copper busbar to be welded. The calibration component can be a combination of bolt holes and bolts.

[0117] Specifically, the positioning plate includes a first positioning plate 701 and a second positioning plate 702. The first positioning plate 701 forms a first positioning surface 7011 to position one of the copper bars to be welded, and the second positioning plate 702 forms a second positioning surface 7021 to position the other copper bar to be welded. During the specific positioning process, the copper bar to be welded is placed between the first positioning member 7 and the second positioning member 8. By adjusting the displacement of the second positioning member 8, the abutting surface 805 and the positioning surface are fixed to the two side end surfaces of the copper bar to be welded, thereby completing the process of positioning and fixing the copper bar to be welded.

[0118] On the basis of the above, the second positioning member 8 includes:

[0119] Connecting member 801, connected to the positioning plate;

[0120] An adjusting rod 802 connected to the connecting member 801;

[0121] A fixing member 803 slidably connected to the adjusting rod 802 ;

[0122] An adjusting member 804 is screwed to the adjusting rod 802;

[0123] Wherein, the axis of the adjusting rod 802 is consistent with the second direction;

[0124] The adjusting member 804 can adjust the fixing member 803 to move toward or away from the positioning plate;

[0125] Furthermore, the end surface of the fixing member 803 facing the copper busbar to be welded constitutes the abutting surface 805.

[0126] Specifically, the fixing member 803 is an annular fixing ring, which forms an abutment surface 805 facing the end face of the copper busbar to be welded. By rotating the adjusting member 804, the fixing member 803 is driven to move along the axial direction of the adjusting rod 802, that is, the second direction, thereby applying a force toward the first positioning member 7 to the copper busbar to be welded, and finally achieving the positioning and fixation of the copper busbar to be welded.

[0127] In a specific embodiment, the adjusting rod 802 is formed with an external thread, and the adjusting member 804 is formed with an internal thread, and the two form a threaded fit.

[0128] In a specific embodiment, the connecting member 801 includes a first connecting plate 8012 and a second connecting plate 8013;

[0129] Wherein, the first connecting plate 8012 is connected to the positioning plate;

[0130] Wherein, the second connecting plate 8013 is connected to a side wall surface of the mounting groove 9;

[0131] Furthermore, the first connecting plate 8012 and the second connecting plate 8013 are both provided with a plurality of adjustment slots 8011;

[0132] The adjustment rod 802 can be assembled into any of the adjustment slots 8011 .

[0133] The first connecting plate 8012 is connected to the positioning plate. The first connecting plate 8012 and the positioning plate are arranged perpendicularly. The second connecting plate 8013 is mounted on the sidewall of the mounting slot 9 and is arranged opposite the first connecting plate 8012. To accommodate different copper busbar splicing configurations, the first and second connecting plates 8012 and 8013 are provided with a plurality of adjustment slots 8011 arranged along their respective lengths. The adjustment rod 802 can be mounted in different adjustment slots 8011.

[0134] Wherein, both ends of the adjusting rod 802 have a limiting structure, which is used to prevent the adjusting rod 802 from rotating. Specifically, the limiting structure can be in the form of a card block to be clamped in the adjusting slot 8011.

[0135] On the basis of the above, it includes a support assembly 14;

[0136] The support assembly 14 is rotatably connected to any one or more of the adjustment slots 8011;

[0137] The bottom of the mounting groove 9 and the center axis of the support assembly 14 have a height H3;

[0138] Moreover, H3=H2.

[0139] Specifically, the support assembly 14 is a roller that is rotatably connected to the adjustment slot 8011. The roller is used to provide support for the copper busbar to be welded. As previously mentioned, since the second positioning member 8 tends to provide a fixing force rather than a supporting force, the roller can be used to support the copper busbar to be welded when it is long.

[0140] like Figures 1 to 7 As shown, the second embodiment of the present invention provides a copper busbar welding machine, comprising:

[0141] The copper busbar welding positioning frame 1 as described in any one of the above embodiments;

[0142] The table of the copper busbar welding positioning frame 1 is divided into an installation table 102 and a working table 101;

[0143] A first drive assembly 2 having a reciprocating motion along a third direction and along a second direction;

[0144] The third direction is a direction perpendicular to the table top;

[0145] a welding gun assembly 3 connected to the first driving assembly 2;

[0146] A wire feeding assembly 4 connected to the mounting table 102;

[0147] A support 5 is provided on the work surface 101 and is used to support the copper busbar to be welded;

[0148] The pressure plate assembly 6 is arranged on the installation table 102 and is used to press the copper busbar to be welded.

[0149] In this embodiment, the table top of the rack 1 is divided into a working table top 101 and an installation table top 102 .

[0150] The mounting surface 102 is provided with a first support arm 1001, and the first drive assembly 2 is mounted on the first support arm 1001. The first drive assembly 2 includes a first drive member 201 that moves in the second direction and a second drive member 202 that moves in the third direction. The first drive member 201 may be an electric rail, and the second drive member 202 may be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. The welding gun assembly 3 is connected to the driving end of the second drive member 202 to be driven by the first and second drive members 201 and 202, and is movable in both the third and second directions.

[0151] The mounting table 102 is provided with a second arm 1002, and the pressing plate assembly 6 is assembled on the second arm 1002. The pressing plate assembly 6 can be displaced along the third direction to press the copper busbar to be welded below.

[0152] The wire feeding assembly 4 is a device for feeding welding wire.

[0153] Based on the above, it was further discovered that in the prior art, the ends of two copper busbars to be welded are usually stacked and welded at the stacked position. The reason why the ends of the two copper busbars to be welded cannot be butted together is that due to the high thermal conductivity of the copper busbars, when welding with a large current, a high temperature is generated at the welding position, making the butt welding position extremely easy to be welded through. Therefore, the only way to weld is to stack the two copper busbars together.

[0154] In this embodiment, the pressure plate assembly 6 presses the two copper bars to be welded on the same plane, which allows the ends of the copper bars to be welded to be welded in a butt-jointed manner. Therefore, it is necessary to control the thermal management of the welding process.

[0155] Based on this, the work surface 101 is sunken to form a mounting groove. This mounting groove is a through-groove structure. Specifically, the mounting groove is open in a direction perpendicular to the welding position, thereby forming a semi-open area with a significant gap from the copper busbar to be welded. When the copper busbar is welded, the heat transfer path is divided into two parts. One part is transferred from the support 5 to the mounting groove, which is recorded as the first conductive heat, and the other part is transferred along the copper busbar to be welded, which is recorded as the second conductive heat.

[0156] Regarding the first heat transfer, heat is transferred along the support 5 to the surface of the mounting slot, where it is then conducted and dissipated. On the one hand, because the mounting slot is a sunken structure, it does not come into contact with the non-welded portion of the copper busbar, thus preventing heat transfer from the non-welded portion of the copper busbar to the mounting slot. In other words, the mounting slot is only used to conduct heat from the welded portion, efficiently transferring heat away from the welded portion, thereby preventing heat accumulation in the welded portion and ensuring orderly thermal management.

[0157] Regarding the second type of heat conduction, which is the heat conduction mode of the copper busbar to be welded, it can be seen that the larger the area of ​​the copper busbar to be welded is exposed to the air, the better its heat dissipation effect. Therefore, as mentioned above, when the mounting groove is present, it can avoid direct contact with the copper busbar to be welded, allowing both to be in contact with the air and achieve independent heat dissipation.

[0158] It was further discovered that when the copper busbar to be soldered is mounted on the support assembly 14, it forms a heat dissipation channel with the mounting slot, allowing heat conducted between the two to be further dissipated through the heat dissipation channel. Furthermore, due to the limited volume of the heat dissipation channel, when the air within it is heated, it will inevitably flow out relatively quickly and form convection heat exchange with the air in the external environment, further improving the thermal management of the copper busbar to be soldered.

[0159] The mounting slot is a through-slot structure, meaning it has only a lower end face and two side walls. The upper end face of the heat dissipation channel is formed by the copper busbar to be soldered, with through-hole structures formed at both ends to facilitate the rapid discharge of hot air. Specifically, there is a certain temperature difference between the temperature of the copper busbar to be soldered (direct heat conduction) and the wall surface of the mounting slot (indirect heat conduction). Although the lower end face and the two side walls cannot directly exchange heat with the atmospheric environment through convection, the temperature difference formed internally promotes air flow within the heat dissipation channel. The higher-temperature copper busbar heats the air below it, causing its density to decrease and rise, while the relatively lower-temperature lower end face and the two side walls increase the density of the nearby air and cause it to sink. This temperature difference-driven air flow can form internal convection within the channel, thereby enhancing the heat exchange effect. Moreover, the lower end face and the two side walls inside the heat dissipation channel will dissipate heat to the copper busbar surface through radiation at high temperatures. Thermal radiation is an important method of heat transfer, especially under high temperature difference conditions. Through radiative heat exchange from the front and rear walls and bottom, heat from the copper busbar is effectively transferred to the various walls of the heat dissipation channel, where it is then dissipated through the walls. Internal temperature differences still drive air circulation within the channel, effectively dissipating heat evenly throughout the entire heat dissipation channel. This prevents localized heat accumulation and maintains uniform surface temperature of the copper busbar, which improves soldering quality and equipment stability. Because the heat dissipation channel has a unique through-hole structure, this design ensures that internal hot air is discharged through a single outlet, effectively preventing heat retention. The convection circulation formed by the hot air within the channel helps maintain temperature uniformity within the channel, thereby improving the thermal management capabilities of the entire system.

[0160] Wherein, the pressing plate assembly 6 includes:

[0161] A first pressing plate 601 and a second pressing plate 602;

[0162] The first pressing plate 601 and the second pressing plate 602 are respectively connected to the mounting table 102 via a second driving assembly 11;

[0163] Wherein, a welding channel is formed between the first pressing plate 601 and the second pressing plate 602;

[0164] Furthermore, the welding gun assembly 3 is displaced 603 along the welding channel.

[0165] In this embodiment, the first pressing plate 601 is used to press and clad one of the copper busbars to be welded, and the second pressing plate 602 is used to press and clad the other copper busbar to be welded.

[0166] The second driving assembly 11 can apply a force on the first pressing plate 601 and the second pressing plate 602 toward the copper busbar to be welded, thereby causing the copper busbar to be welded to be pressed onto the base 5 .

[0167] The welding channel is used for welding by the welding gun assembly 3. That is, the welding gun channel is open, which can expose the weld to be welded to the external environment. When the welding gun assembly 3 is welding, a double-sided forming process can be achieved by only welding on one side. This is because, as mentioned above, the copper busbar welding machine provided by the present application has good thermal management, thereby effectively and quickly dissipating the heat from the welded part, avoiding the welded part from being welded through or the occurrence of structural defects.

[0168] In one embodiment, the second driving assembly 11 is a pneumatic cylinder, a hydraulic cylinder or an electric push rod.

[0169] In this embodiment, an adjustment mechanism 12 is also included;

[0170] Wherein, the welding gun assembly 3 is connected to the first driving assembly 2 through the adjustment mechanism 12;

[0171] Furthermore, the adjustment mechanism 12 is configured to adjust the displacement of the welding gun assembly 3 in the first direction and the third direction.

[0172] In this embodiment, the adjustment mechanism 12 is used to precisely adjust the position of the welding gun assembly 3. Specifically, the adjustment mechanism 12 can employ a manual cross slide to adjust the position of the welding gun assembly 3 in the first and third directions. As cross slide technology is relatively mature in the prior art, its further description is omitted here.

[0173] In specific applications, when there is a position deviation between the welding gun assembly 3 and the weld to be welded, the position of the welding gun assembly 3 can be finely adjusted by the adjustment mechanism 12 to ensure the welding quality.

[0174] In this embodiment, the wire feeding assembly 4 includes:

[0175] A driving device 401 connected to the mounting surface 102 of the frame 1;

[0176] A feeding wheel 402 is connected to the driving end of the driving device 401;

[0177] Among them, a wire feeding channel 403 is formed between the plurality of feeding wheels 402;

[0178] The wire feed tube 404 is connected to one side of the welding gun assembly 3 .

[0179] In this embodiment, a driving device 401 (e.g., a stepper motor) drives a feed wheel 402 to rotate. The welding wire is clamped in a wire feed channel 403 and fed to a wire feed tube 404 as the feed wheel 402 rotates. The welding wire is fed from the wire feed tube 404 to cooperate with the welding gun assembly 3 to weld the copper busbar to be welded.

[0180] In one embodiment, the feeding wheels 402 are in multiple groups.

[0181] In a specific embodiment, the feed wheel 402 has rings with various diameters to accommodate welding wires with different diameters.

[0182] In one embodiment, the welding wire may be wound onto a material roller that is rotatably connected to the first arm 1001 .

[0183] In this embodiment, a heat insulation plate 13 made of graphite is provided along the center line of the support platform 5 .

[0184] In this embodiment, since the welding temperature is relatively high and the thermal conductivity of the copper busbar is high, a relatively high temperature is generated at the portion to be welded.

[0185] Therefore, a heat shield 13 is provided at the center line of the support platform 5. In other words, the heat shield 13 corresponds to the position of the weld to be welded, so that the liquid solder can be received and solidified on the other side of the copper busbar to be welded (the side away from the welding gun assembly 3), thereby achieving the function of single-sided welding and double-sided forming.

[0186] Moreover, it should be noted that the copper busbar welding machine provided in this embodiment is not intended to provide direct contact heat conduction for the part to be welded. In other words, it is not intended to directly set a cooling device on the part to be welded, nor is it intended to directly water-cool the part to be welded. The reason is that the heat insulation board 13 provided in this embodiment is expected to be able to withstand a certain amount of heat, and this part of the heat helps the flow of liquid solder, so that the liquid solder is more evenly filled into the weld to be welded, and the process of double-sided molding is realized. The rest of the area of ​​the support 5 (referring to the area excluding the heat insulation board 13) is used to conduct heat to the non-welding parts, which helps to quickly extract heat and avoid problems such as excessive heat in the weld to be welded and welding through.

[0187] In one embodiment, a forming groove is provided along the center line of the heat insulation board 13;

[0188] Wherein, the forming groove is concave along the second direction to form an arc structure.

[0189] In this embodiment, the arc-shaped forming groove is used to receive liquid solder. When the liquid solder solidifies, a weld structure with a certain shape is formed, thereby avoiding excessive correction of the weld at this position at a later time.

[0190] In this embodiment, a cooling assembly is further included, which is in communication with the support platform 5 and the pressure plate assembly 6;

[0191] The cooling assembly delivers a cooling medium to the support platform 5 and the pressure plate assembly 6 .

[0192] In this embodiment, the support platform 5 and the pressure plate assembly 6 are provided with a cooling assembly. The cooling assembly can be in the form of a liquid cooling channel, which is used to liquid cool the non-welding area of ​​the copper busbar to be welded to ensure that heat is effectively dissipated.
