TECHNICAL FIELD

[0001] The application relates to the technical field of automobile copper bar processing, and more particularly to the technical field of automobile copper bar welding processing, and specifically relates to a welding device for automobile copper bars. BACKGROUND

[0002] New energy electric vehicles use battery packs to provide electric energy, convert electric energy into mechanical energy through electric motors to drive the movement of the vehicle, and the battery pack is the "heart" of the electric vehicle and is the core power source. The automobile copper bar, as the "blood vessels" of the electric vehicle, is a high-conductivity carrier for connecting the battery pack, the electric motor and the electric control system and other core components due to its conductivity, heat dissipation and stability.

[0003] In order to ensure the electrical connection quality and solve the mechanical strength and vibration resistance of the electrical connection in the high-current scenario of new energy electric vehicles, terminals are usually welded at the end of the copper bar for reliable connection of the copper bar.

[0004] A welding device and method for a composite bar are disclosed in Chinese Patent No. CN118543950B, which includes a base, an ultrasonic welder body for welding fixed on the base, a placement seat fixed on the base, a first mechanical clamp jaw for clamping a copper bar provided at one end of the placement seat, and a second mechanical clamp jaw for clamping an aluminum bar provided at the other end of the placement seat. The base is fixed with a moving assembly on both sides for adjusting the positions of the first and second mechanical clamp jaws.

[0005] Based on the above-mentioned patent and in combination with the existing scheme and actual production and processing, the current automobile copper bar welding device still has some problems, for example:

[0006] In the above-mentioned patent, the first and second mechanical clamp jaws are used to clamp and fix two copper bar workpieces to be welded respectively, and the clamping and fixing method is the same as that of the existing copper bar welding device, that is, the clamping and fixing of the copper bar workpieces is achieved by driving the clamping pieces to open and close through electricity or gas.

[0007] However, in the actual operation of clamping and fixing the copper bar workpieces, it is necessary to accurately ensure the placement position of the copper bar workpieces on the clamping pieces and the extension distance of the copper bar workpieces on the clamping pieces to meet the use requirements that the two copper bar workpieces can be accurately butt-jointed and the butt-joint seam of the two copper bar workpieces can be accurately corresponded to the welding equipment. The clamping and fixing method in the above-mentioned patent and the clamping and fixing method in the existing copper bar welding device can only meet the single clamping requirement and cannot guarantee the accurate positioning of the clamping of the copper bar workpieces, affecting the operation convenience.

[0026] Compared with the prior art, the present invention has at least the following beneficial effects: the welding device for automotive copper busbars accurately ensures the placement position and extension distance of the terminals or copper busbars in the clamping, realizes rapid and accurate positioning in the clamping, and realizes automatic reversal and flipping of the terminals and copper busbars in the welding, meeting the usage requirements of all-round welding and ensuring welding quality.

[0027] 1. After the terminal or copper busbar is connected to the clamping plate, the front and rear sides of the terminal or copper busbar are respectively attached to the claw body of the front limiting claw and the claw body of the rear limiting claw. Through the limiting action of the limiting claw, the placement position of the terminal or copper busbar on the clamping plate is accurately ensured, and the terminal or copper busbar is accurately positioned during clamping, which is used to assist the accurate connection between the terminal and the copper busbar in the future.

[0028] Furthermore, the linkage mechanism formed by the combination of the drive block, the adjusting plate and the limiting claw is used to drive the two limiting claws to slide relative to each other to adjust the distance. Through the adjustable structure, the limiting component can be used for terminals or copper busbars of different widths, effectively improving the applicability.

[0029] Furthermore, after the terminal or copper busbar is assembled on the clamping plate, the end of the terminal or copper busbar is attached to the upper end of the limiting baffle. Through the limiting baffle, the extension distance of the terminal or copper busbar on the clamping plate is precisely ensured. That is, the extension distance of the terminal on the left clamping mechanism is the same as the extension distance of the copper busbar on the right clamping mechanism, so as to achieve precise positioning of the extension distance of the terminal or copper busbar during clamping. In addition, in conjunction with the limiting claw, the terminal or copper busbar is precisely positioned. Unlike the existing copper busbar workpiece clamping and positioning, which requires manual measurement and repeated adjustment, this method achieves fast and accurate positioning during clamping, reduces assembly errors caused by manual intervention, and ensures ease of operation.

[0030] 2. The second linkage ring is driven by the second lever to slide repeatedly. The sliding fit between the pin and the annular groove group makes the transmission ring drive the sub-shell to rotate intermittently. This realizes the automatic reversal and flipping of the terminal and copper busbar during welding. Unlike the existing method that can only perform welding on one side, this method meets the needs of welding in all directions, effectively enhances the mechanical strength of the weld, and ensures the welding quality.

[0031] Furthermore, in the welding of terminals and copper busbars, the automatic reversing and flipping mechanism is used to meet the needs of alternating welding or segmented welding, avoiding uneven heating on one side of the terminal and copper busbar joint due to continuous heating, and effectively reducing the risk of bending deformation.

[0053] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0054] Example 1:

[0055] This invention provides a technical solution: a welding device for automotive copper busbars, which addresses the cumbersome positioning operation requiring manual measurement during terminal or copper busbar clamping and fixing, which cannot achieve rapid and accurate positioning, and cannot accurately ensure the placement position and extension distance of the terminal or copper busbar, affecting the ease of operation. Through the positioning function of the limiting component 12, the placement position of the terminal or copper busbar on the clamping plate 10 is accurately ensured, and through the positioning function of the limiting baffle 19, the extension distance of the terminal or copper busbar on the clamping plate 10 is accurately ensured, so that the terminal or copper busbar can be quickly and accurately positioned on the clamping mechanism 7. Thus, the clamping mechanism 7 accurately clamps the terminal or copper busbar, and then performs precise docking between the terminal and the copper busbar.

[0056] This technical solution: Please refer to Figures 1-13 A welding device for automotive copper busbars includes a cabinet 1, an integrated frame section is vertically arranged in the middle of the rear side of the cabinet 1, a horizontal table panel 2 is fixedly connected to the upper side of the cabinet 1 by bolts, a pedestal frame 4 is slidably connected to the frame section of the cabinet 1 by a first cylinder 3, and a welding head 6 is lifted and lowered on the pedestal frame 4 by a second cylinder 5.

[0057] It also includes a clamping mechanism 7, which is vertically mounted on the table panel 2 and is symmetrically arranged about the vertical central axis of the table panel 2. The left clamping mechanism 7 is used to quickly and accurately position and clamp the terminals, and the right clamping mechanism 7 is used to quickly and accurately position and clamp the copper busbars. The left clamping mechanism 7 and the right clamping mechanism 7 on the table panel 2 form a relative sliding structure, and the operating terminals and copper busbars are automatically connected directly below the welding head 6.

[0058] Specifically, in this technical solution, when the terminal or copper busbar is placed onto the clamping mechanism 7, the positioning operation of the terminal or copper busbar on the clamping plate 10 is performed with the assistance of the limiting component 12. Figure 1 , Figure 3 , Figure 5 and Figure 12 As shown, the limiting assembly 12 includes a limiting claw 23, an adjusting assembly 24, and a bidirectional lead screw 25. The limiting claw 23 is symmetrically arranged about the horizontal central axis of the clamping plate 10. Since the adjusting assembly 24 is placed between the two limiting claws 23 and is symmetrically arranged about the vertical central axis of the limiting claws 23, the two adjusting assemblies 24 are driven to slide relative to each other in the clamping plate 10 by the bidirectional lead screw 25. The two limiting claws 23 are also driven to slide relative to each other in the clamping plate 10 by the operation of the two adjusting assemblies 24. After the two limiting claws 23 are slidably adjusted, the distance between the two limiting claws 23 is adapted to the width of the terminal or copper busbar.

[0059] Since the clamping plate 10 is symmetrically arranged about the horizontal central axis of the sub-shell 9, and the clamping plate 10 is hollow with a plate cavity, the lower cavity wall of the plate cavity is provided with through slots at equal intervals for connecting to the outside. Since the limiting claw 23 is composed of two parts, a horizontal plate part and a claw body part, the claw body part is arranged vertically at equal intervals on the horizontal plate part. After the limiting claw 23 is installed, the horizontal plate part is movably locked in the plate cavity of the clamping plate 10, and the claw body part is movably inserted through the through slots in the plate cavity of the clamping plate 10 and extends outwards. The terminal or copper busbar is inserted into the gap between the two clamping plates 10, so that the terminal or copper busbar overlaps on the clamping plate 10, and the terminal or copper busbar is fitted with the claw body part of the limiting claw 23 after installation. In this way, the placement position of the terminal or copper busbar on the clamping plate 10 is accurately ensured, and the terminal or copper busbar is accurately positioned in the center of the clamping plate 10.

[0060] Since the clamping mechanism 7 is symmetrically arranged about the vertical central axis of the table panel 2, and since the left clamping mechanism 7 is used to clamp and fix the terminal, the terminal is accurately positioned in the center of the upper clamping plate 10 by the limiting component 12 on it, and since the right clamping mechanism 7 is used to clamp and fix the copper busbar, the copper busbar is accurately positioned in the center of the upper clamping plate 10 by the limiting component 12 on it, when the left clamping mechanism 7 and the right clamping mechanism 7 slide relative to each other, the end of the terminal can be precisely connected to the end of the copper busbar.

[0061] Meanwhile, in the above technical solutions, according to Figure 5 , Figure 12 and Figure 13 As shown, the end of the bidirectional lead screw 25 facing the welding head 6 is the inward end, and the end away from the welding head 6 is the outward end. Both the inward and outward ends of the bidirectional lead screw 25 are fixedly clamped with bearings. After the bidirectional lead screw 25 is installed, the inward end, along with the bearing, is movably inserted into one side of the cavity wall of the clamping plate 10, and the outward end, along with the bearing, movably passes through the other side of the cavity wall of the clamping plate 10 and extends outward. Furthermore, the outward extension of the bidirectional lead screw 25 is sleeved and fixedly connected to a throttle by bolts. By turning the throttle, the bidirectional lead screw 25 is driven to rotate within the cavity of the clamping plate 10.

[0062] Since the threaded direction of the inner section of the double-acting screw 25 is opposite to that of the outer section, and since the adjusting assembly 24 includes a drive block 2401 and an adjusting plate 2402, the left adjusting assembly 24 corresponds to the inner section of the double-acting screw 25. That is, after the left drive block 2401 is installed, it is connected to the inner section of the double-acting screw 25 in a through manner, and the two achieve threaded transmission. Since the right adjusting assembly 24 corresponds to the outer end of the double-acting screw 25, that is, after the right drive block 2401 is installed, it is connected to the outer section of the double-acting screw 25 in a through manner, and the two also achieve threaded transmission, after the double-acting screw 25 is driven to rotate, the two adjusting assemblies 24 form a relative sliding structure in the plate cavity of the clamping plate 10, that is, the two drive blocks 2401 are driven to move relative to each other in the plate cavity of the clamping plate 10.

[0063] Since the drive block 2401 is installed and is movably locked in the middle of the plate cavity of the clamping plate 10, the square structure of the drive block 2401 allows the drive block 2401 to be positioned in a movable state within the clamping plate 10, and it is restricted to linear sliding only. The two drive blocks 2401 slide relative to each other within the plate cavity of the clamping plate 10 after being driven.

[0064] Since both ends of the adjusting plate 2402 are rotatably connected to shaft columns, and they are symmetrically arranged about the horizontal central axis of the driving block 2401, the two adjusting plates 2402 are used to connect the two limiting claws 23 to the driving block 2401. Since the driving block 2401 has integrated connecting ears on both the front and rear sides, after the adjusting plate 2402 is installed, one end of it overlaps the connecting ear of the driving block 2401, and the shaft column is inserted and fixed to the connecting ear by bolts. Since the horizontal plate of the limiting claw 23 has a through groove, after the adjusting plate 2402 is installed, the other end of it is movably inserted into the through groove of the horizontal plate of the limiting claw 23, and the shaft column is inserted and fixed to the through groove wall of the horizontal plate by bolts, so that the driving block 2401, the adjusting plate 2402 and the limiting claw 23 form a linkage mechanism.

[0065] Since the adjusting plate 2402 is set at an angle on the driving block 2401, the two adjusting plates 2402 are combined to form an "eight" shape. Since the left and right adjusting components 24 are set in opposite directions, that is, the adjusting plate 2402 on the left adjusting component 24 and the adjusting plate 2402 on the right adjusting component 24 are also combined to form an "eight" shape. After the driving block 2401 is driven to slide, one end of the adjusting plate 2402 rotates and flips on the connecting ear of the driving block 2401, and the other end of the adjusting plate 2402 rotates and flips on the horizontal plate of the limiting claw 23. The two limiting claws 23 are pushed or pulled to slide relative to each other through the linkage mechanism formed between the driving block 2401, the adjusting plate 2402 and the limiting claw 23, so as to adjust the distance between the two limiting claws 23. That is, the limiting component 12 is adjustable to adapt to terminals or copper busbars of different widths.

[0066] Specifically, in this technical solution, when the terminal or copper busbar is placed onto the clamping mechanism 7, the positioning operation of the extension distance of the terminal or copper busbar on the clamping plate 10 is performed with the assistance of the limiting baffle 19. Figure 1 , Figure 10 and Figure 11 As shown, in the initial state, the limiting baffle 19 is positioned on the main housing 8 by the pressing action between the connecting plate 21 and the pushing plate 22, and the upper end of the limiting baffle 19 corresponds to the side of the clamping plate 10 near the welding head 6. The terminal or copper busbar is inserted into the gap between the two clamping plates 10, so that the end of the terminal or the end of the copper busbar extends through the side of the clamping plate 10 near the welding head 6, and the end of the terminal or the end of the copper busbar is in contact with the upper end of the limiting baffle 19. In this way, the extension distance of the terminal or copper busbar on the clamping plate 10 is accurately ensured, and the extension distance of the terminal or copper busbar on the clamping plate 10 is accurately positioned.

[0067] Since the left clamping mechanism 7 is used to clamp and fix the terminal, the extension distance of the terminal on the clamping plate 10 is accurately positioned by the limiting baffle 19 on it. Since the right clamping mechanism 7 is used to clamp and fix the copper busbar, the extension distance of the copper busbar on the clamping plate 10 is accurately positioned by the limiting baffle 19 on it, so that the positioning distance of the copper busbar extending on the clamping plate 10 is equal to the positioning distance of the terminal extending on the clamping plate 10. When the left clamping mechanism 7 and the right clamping mechanism 7 slide relative to each other, the joint between the end of the terminal and the end of the copper busbar can be aligned directly below the welding head 6.

[0068] Specifically, in this technical solution, the clamping mechanism 7 includes a main housing 8, a secondary housing 9, and a clamping plate 10. The clamping plate 10 clamps the terminals or copper busbars. Figure 1 , Figure 3 , Figure 4 ,Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the end of the main housing 8 facing the welding head 6 is the inward end, and the end away from the welding head 6 is the outward end. Since the lower side of the outer wall of the main housing 8 facing inward is provided with an integrated connecting seat, a shaft column is inserted and fixedly connected to the connecting seat by bolts, and a bearing is fixedly clamped on the shaft column of the connecting seat. Since the first lever 17 has a "Y" shaped structure, it is divided into two upper brackets at the upper end and a lower bracket at the lower end. After the first lever 17 is installed, its middle part is movably clamped on the lower connecting seat of the main housing 8 facing inward. The shaft column of the lower connecting seat of the main housing 8 facing inward, along with the bearing, is movably inserted into the middle of the first lever 17, so that the first lever 17 is positioned on the main housing 8 in a movable state.

[0069] Because an integrated connecting seat is provided on the lower side of the outer shell wall of the main housing 8 facing outwards, a shaft column is inserted and rotatably connected to the outer shell end of the third cylinder 18. After the third cylinder 18 is installed, the outer shell end, along with the shaft column, is movably inserted into the lower connecting seat on the outer side of the main housing 8, so that the outer shell end of the third cylinder 18 forms a rotating structure on the lower connecting seat on the outer side of the main housing 8. Furthermore, because an open slot is provided at the end of the lower bracket in the first shifter 17, a shaft column is inserted and rotatably connected to the output end of the third cylinder 18. After the first shifter 17 and the third cylinder 18 are assembled... The output end of the third cylinder 18, along with its shaft, is movably inserted into the slot of the lower bracket of the first shifter 17. The shaft on the output end is inserted into and fixedly connected to the end of the lower bracket of the first shifter 17 with bolts, so that the output end of the third cylinder 18 forms a rotating structure on the lower bracket of the first shifter 17. Through the rotation between the third cylinder 18 and the main housing 8, and through the rotation between the third cylinder 18 and the first shifter 17, the third cylinder 18 is started to retract and operate, pulling the first shifter 17 to flip on the lower connecting seat at the inner end of the main housing 8.

[0070] Since the outer ring wall of the first linkage ring 15 is vertically provided with an integrated pin portion on both the front and rear sides, and the ends of the two pin portions are fixedly engaged with bearings, and since the ends of the two upper brackets of the first lever 17 are provided with through grooves, after the first lever 17 and the first linkage ring 15 are assembled, the two pin portions of the first linkage ring 15, along with the bearings, are respectively movably inserted into the grooves of the two upper brackets of the first lever 17, so that the bearings of the pin portions of the first linkage ring 15 are movably engaged in the grooves of the upper brackets of the first lever 17. When the first lever 17 is pulled and flipped, the pin portions of the first linkage ring 15 slide in the upper brackets of the first lever 17, and drive the first linkage ring 15 to move.

[0071] Since the main housing 8 has a cylindrical structure with a through-hole circular cavity, the front and rear shell walls of the main housing 8 facing inward are provided with through-hole sliding grooves that communicate with the circular cavity. Since the center of the first linkage ring 15 coincides with the center of the main housing 8, after the first linkage ring 15 is installed, it is movably locked in the circular cavity of the main housing 8 and is movably sleeved on the outside of the secondary housing 9. The two pins of the first linkage ring 15 are respectively movably inserted through the two sliding grooves at the inner end of the main housing 8 and extend outward, so that the first linkage ring 15 is movably positioned in the gap between the main housing 8 and the secondary housing 9. When driven, the first linkage ring 15 slides in the circular cavity of the main housing 8.

[0072] Since the first linkage ring 15 has a hollow ring body with an open ring cavity, and an integrated limiting protrusion is provided on the inner ring wall of the first linkage ring 15, the limiting protrusion is set with the same ring center as it. Since the outer ring wall of the inclined ring 16 has a limiting ring groove with the same ring center as it, the inclined ring 16 is placed in the ring cavity of the first linkage ring 15, and the limiting protrusion in the first linkage ring 15 is movably locked in the limiting ring groove in the inclined ring 16, so that the inclined ring 16 is movably positioned in the first linkage ring 15. When the first linkage ring 15 is driven to slide, it drives the inclined ring 16 to slide synchronously, and the inclined ring 16 slides along the outer side of the sub-shell 9.

[0073] Because the sub-shell 9 has a cylindrical structure and a through square cavity, spring compartments are provided at the four corners of the square cavity wall. Two clamping plates 10 are symmetrically arranged inside the square cavity of the sub-shell 9. The clamping plates 10 have a block-shaped structure. At the four corners of the side facing the square cavity wall of the sub-shell 9, an integrated guide post is vertically arranged. The end of the guide post is snapped and fixed to a limiting plate by bolts. After the clamping plates 10 are installed, they are movably snapped into the square cavity of the sub-shell 9. The guide post and the limiting plate are movably inserted into the spring compartment of the square cavity of the sub-shell 9, so that the two clamping plates 10 are movably positioned in opposite directions inside the sub-shell 9.

[0074] Since a through hole is provided in the middle of the square cavity wall in the sub-shell 9, and since the inclined column 1001 is welded and fixed in a vertical state in the middle of the side of the clamping plate 10 facing the square cavity wall in the sub-shell 9, when the clamping plate 10 is assembled with the sub-shell 9, the inclined column 1001 moves through the through hole in the square cavity of the sub-shell 9 and extends outward.

[0075] Since the inclined surfaces of the inclined columns 1001 in the upper clamping plate 10 and the inclined surfaces of the inclined columns 1001 in the lower clamping plate 10 are arranged in opposite directions, and since the inclination angle of the inclined surface in the inclined column 1001 matches the inclination angle of the inclined surface in the inclined ring 16, and the arc dimension of the inclined surface in the inclined column 1001 matches the arc dimension of the inclined ring 16, and since the inclined surface in the inclined ring 16 and the inclined surface in the inclined column 1001 are connected by a pressing method, the inclined ring 16 pushes the inclined column 1001 after being driven to slide. Through the sliding cooperation between the inclined surface in the inclined ring 16 and the inclined surface in the inclined column 1001, the inclined columns 1001 in the upper clamping plate 10 and the inclined columns 1001 in the lower clamping plate 10 are pushed to slide synchronously, that is, the upper clamping plate 10 and the lower clamping plate 10 slide relative to each other in the square cavity of the sub-shell 9.

[0076] Since a first spring 11 is installed at the sliding connection between the clamping plate 10 and the sub-shell 9, the first spring 11 is movably sleeved on the guide post part in the clamping plate 10 and placed in the spring chamber of the square shell cavity wall in the sub-shell 9. One end of the spring 11 presses against the spring chamber wall and the other end presses against the limiting plate in the clamping plate 10. When the clamping plate 10 is driven to slide in the sub-shell 9, the first spring 11 is compressed and undergoes elastic deformation.

[0077] Since the end of the sub-shell 9 facing the welding head 6 is the inward end, and the end away from the welding head 6 is the outward end, and since after the clamping plate 10 is assembled with the sub-shell 9, one end of the clamping plate 10 moves through the inward end cavity of the square shell cavity in the sub-shell 9 and extends outward, and the other end moves through the outward end cavity of the square shell cavity in the sub-shell 9 and extends outward, after the terminal or copper busbar is assembled on the clamping mechanism 7, the terminal or copper busbar passes through the gap between the two clamping plates 10. The positioning position and extension distance of the terminal or copper busbar are accurately positioned by the limiting claw 23 and the limiting baffle 19 respectively. When the upper and lower clamping plates 10 slide relative to each other, the terminal or copper busbar is clamped and fixed.

[0078] Conversely, by starting the third cylinder 18 to extend and operate, the first lever 17 is pushed to reset and flip on the lower connecting seat at the inner end of the main housing 8. After the first lever 17 is pushed to reset and flip, the first linkage ring 15 is driven to drive the inclined ring 16 to reset and slide within the circular cavity of the main housing 8, and the inclined ring 16 and the inclined column 1001 lose their pressure. The elastic deformation of the first spring 11 is used to reset and drive the two clamping plates 10 to reset and slide in opposite directions within the square cavity of the secondary housing 9, thereby releasing the clamping effect of the two clamping plates 10.

[0079] Meanwhile, in the above technical solutions, according to Figure 5 and Figure 12As shown, since the side of the clamping plate 10 away from the square cavity wall in the sub-shell 9 is fixedly connected to a rubber pad by bolts, the upper and lower clamping plates 10 play an anti-slip role when clamping and fixing the terminals or copper busbars, thus ensuring the stability after clamping.

[0080] Meanwhile, in the above technical solutions, according to Figure 5 and Figure 12 As shown, since the extension distance of the claw body in the limiting claw 23 is less than half the thickness of the terminal or copper busbar, when the upper and lower clamping plates 10 clamp the terminal or copper busbar, the extension of the claw body in the upper limiting claw 23 will not contact the extension of the claw body in the lower limiting claw 23. That is, the extension of the claw body in the limiting claw 23 does not affect the clamping.

[0081] Meanwhile, in the above technical solutions, according to Figure 4 , Figure 6 and Figure 8 As shown, when the two clamping plates 10 clamp and fix the terminals or copper busbars, the inclined surface in the inclined column 1001 and the inclined surface in the inclined ring 16 press together. When the sub-shell 9 rotates, the inclined column 1001 drives the inclined ring 16 to move synchronously, and the inclined ring 16 rotates in the ring cavity of the first linkage ring 15, always maintaining the pushing action of the inclined ring 16 on the inclined column 1001, that is, always maintaining the clamping action of the upper and lower clamping plates 10.

[0082] Specifically, in this technical solution, the terminals on the left clamping mechanism 7 are automatically connected to the copper busbars on the right clamping mechanism 7, according to... Figure 1 , Figure 3 and Figure 7 As shown, the round rod guide rails in the support frame 13 are symmetrically arranged about its horizontal central axis (the round rod guide rail is existing technology and will not be described in detail in the specification). The left and right ends of the rod body of the round rod guide rail are fixedly connected to the lower side of the platform 2 by bolts, and the left and right sections of the rod body of the round rod guide rail are slidably connected to the sliding table (the left and right sliding tables correspond to the left and right support frames 13 respectively). Since the sliding direction of the support frame 13 is parallel to the rod body of the round rod guide rail, and since the sliding tables of the front and rear round rod guide rails are fixedly connected to the two ends of the support frame 13 by bolts, the two support frames 13 are both in a movable state and positioned on the lower side of the platform 2, and the support frame 13 forms a sliding structure on the lower side of the platform 2 with the assistance of the round rod guide rail.

[0083] Since the bidirectional cylinder 14 is installed and fixed on the lower side of the platform 2 by bolts, and is placed between the two left and right support frames 13, its two output ends are respectively inserted and fixed to the two left and right support frames 13 by bolts. When the bidirectional cylinder 14 is started to retract and operate, it drives the two left and right support frames 13 to slide simultaneously and make the two support frames 13 slide relative to each other on the lower side of the platform 2.

[0084] Since the front and rear sections of the table panel 2 are provided with through grooves, and the front and rear sides of the outer wall of the main shell 8 are provided with an integrated connecting frame, after the main shell 8 is installed, the lower end of the connecting frame moves through the groove of the table panel 2 and extends downward. Since the left and right support frames 13 are respectively fixedly connected to the main shell 8 of the left clamping mechanism 7 and the main shell 8 of the right clamping mechanism 7 by bolts, the support frame 13 drives the main shell 8 to slide synchronously, so that the left and right main shell 8 slide relative to each other on the table panel 2, that is, so that the left clamping mechanism 7 and the right clamping mechanism 7 slide relative to each other on the table panel 2.

[0085] Since the secondary housing 9 is located inside the main housing 8, the two form a synchronous sliding structure. Since the terminal is clamped and fixed in the secondary housing 9 on the left clamping mechanism 7 by the clamping plate 10, and the copper busbar is clamped and fixed in the secondary housing 9 on the right clamping mechanism 7 by the clamping plate 10, after the left clamping mechanism 7 and the right clamping mechanism 7 are driven to slide relative to each other, the end of the operating terminal and the end of the copper busbar are automatically connected.

[0086] Since the welding head 6 is located on the vertical central axis of the table panel 2, that is, at the center of the distance between the two clamping mechanisms 7, after the terminal and the copper busbar are connected, the connection seam between them is located directly below the welding head 6.

[0087] Conversely, after the welding between the terminal and the copper busbar is completed, the left clamping mechanism 7 is activated to lose its clamping effect on the terminal, and the right clamping mechanism 7 is activated to lose its clamping effect on the copper busbar. The welded copper busbar is disassembled first. Then, the bidirectional cylinder 14 is activated to extend and operate. The two support frames 13 drive the two main housing seats 8 to slide in opposite directions on the table panel 2. That is, the separation between the left clamping mechanism 7 and the right clamping mechanism 7 is operated to reset them.

[0088] Meanwhile, in the above technical solutions, according to Figure 1 , Figure 10 and Figure 11As shown, the lower end of the connecting plate 21 is provided with an integrated shaft column, on which a roller is rotatably connected. The lower part of the connecting plate 21 is correspondingly provided with a pushing plate 22. In the initial state of the limiting baffle 19, the lower end of the connecting plate 21, along with the roller, is connected to the pushing plate 22 by a pressing manner. Furthermore, the end of the pushing plate 22 facing the welding head 6 is provided with an inclined side wall. After the pushing plate 22 is placed, it is parallel to the sliding direction of the main housing 8 and is fixedly connected to the table panel 2 by bolts. Before the two clamping mechanisms 7 slide relative to each other to connect the terminals and copper busbars, the clamping mechanism 7 is driven to slide initially, causing the roller in the connecting plate 21 to slide along the upper side wall of the pushing plate 22 and slide away from the pushing plate 22 along the inclined side wall of the pushing plate 22. At this time, the pressing effect between the connecting plate 21 and the pushing plate 22 is lost.

[0089] Since the main housing 8 has an integrated tube seat portion vertically installed on the connecting frame, and the lower end of the limiting baffle 19 has an integrated shaft column portion, both ends of which are fixedly clamped with bearings, after the limiting baffle 19 is installed, the shaft column portion and bearings are movably inserted into the tube seat portion in the main housing 8, and the end of the shaft column portion movably passes through the tube seat portion in the main housing 8 and extends outward, so that the limiting baffle 19 is positioned on the main housing 8 in a movable state;

[0090] Because a spring compartment with the same center is provided on the tube seat of the main housing 8, a first torsion spring 20 is installed at the flip connection between the limiting baffle 19 and the main housing 8. After the first torsion spring 20 is installed, it is movably sleeved on the central column of the limiting baffle 19 and placed inside the spring compartment of the tube seat of the main housing 8. One end of the spring spring 20 is engaged with the wall of the spring compartment, and the other end is engaged with the lower end of the limiting baffle 19. Also, because the connecting plate 21 is installed in an inclined state on the limiting baffle 19, and its upper end is sleeved and fixedly connected to the protruding end of the central column of the limiting baffle 19 by bolts, and because the limiting baffle 19 in its initial state... The first torsion spring 20 is set in a stressed state and undergoes elastic deformation. When the connecting plate 21 and the pushing plate 22 lose their pressure, the elastic deformation of the first torsion spring 20 is used to reset, causing the connecting plate 21 to drive the limiting baffle 19 to perform synchronous flipping motion, and causing the limiting baffle 19 to flip down and unfold on the tube seat of the main housing 8. After the limiting baffle 19 is flipped and unfolded, its upper end loses the limiting obstruction to the terminal end or the copper bus end. That is, when the clamping mechanism 7 is driven to continuously slide to connect the terminal and the copper bus, the flipped and unfolded limiting baffle 19 will not affect the connection of the terminal and the copper bus.

[0091] Conversely, when the clamping mechanism 7 is driven to reset and slide, the lower end of the connecting plate 21 slides along the inclined side wall of the pushing plate 22 to the upper side wall of the pushing plate 22 with the assistance of the roller, and the pushing plate 22 presses against the connecting plate 21 again. After the connecting plate 21 drives the limiting baffle 19 to reset and flip synchronously, the first torsion spring 20 is compressed and undergoes elastic deformation again.

[0092] Meanwhile, in the above technical solutions, according to Figure 1 , Figure 10 and Figure 11 As shown, the left limiting baffle 19 is installed on the connecting frame located at the rear of the left main housing 8, and the right limiting baffle 19 is installed on the connecting frame located at the front of the right main housing 8. That is, the placement positions of the limiting baffle 19 in the left clamping mechanism 7 and the limiting baffle 19 in the right clamping mechanism 7 are misaligned. When the left clamping mechanism 7 and the right clamping mechanism 7 slide correspondingly to perform terminal and copper busbar docking, the left and right limiting baffles 19 will dock in a misaligned manner without causing any impact.

[0093] Specifically, in this technical solution, welding is performed using welding head 6, according to... Figure 1 and Figure 2 As shown, after the second cylinder 5 is installed, it is fixedly mounted on the front end of the base frame 4 with bolts, and its output end extends downward through the front end of the base frame 4. After the welding head 6 is installed, it is set in a vertical downward state and is fixedly connected to the output end of the second cylinder 5 with bolts. By controlling the second cylinder 5, the welding head 6 moves up and down at the front end of the base frame 4.

[0094] Since the pedestal frame 4 has integrated guide rods on both the left and right sides, after the pedestal frame 4 is installed, it is horizontally and movably locked in the slot at the upper end of the frame of the cabinet 1. The two guide rods are respectively movably inserted into the slot walls on both sides of the upper end of the frame of the cabinet 1, so that the pedestal frame 4 is movably positioned on the frame of the cabinet 1. After the first cylinder 3 is installed, it is fixedly installed on the upper end of the frame of the cabinet 1 with bolts. The output end is movably inserted into the slot at the upper end of the frame of the cabinet 1, and the output end is inserted into and fixedly connected to the middle of the rear side of the pedestal frame 4 with bolts. By controlling the first cylinder 3, the pedestal frame 4 drives the welding head 6 to slide back and forth on the frame of the cabinet 1.

[0095] Based on the above, the welding head 6 is first lowered by the second cylinder 5 so that it is aligned with the joint between the terminal and the copper busbar. Then, the first cylinder 3 controls the platform frame 4 to slide the welding head 6 back and forth to perform welding on the joint between the terminal and the copper busbar.

[0096] Example 2:

[0097] Based on Embodiment 1, please refer to the following: Figures 14-19 The technical solution shown has the following drawbacks: when welding terminals and copper busbars, if only one side is continuously heated, it is easy to cause one-sided overheating at the connection between the terminal and the copper busbar. As a result, large shrinkage stress is generated, causing bending deformation. At the same time, if only one side is welded, the mechanical strength and stability of the weld between the terminal and the copper busbar are reduced, and it is easy to break due to excessive stress during subsequent use. To address the problem that the existing terminals and copper busbars can only be welded on one side and cannot be automatically reversed and flipped in all directions, thus affecting the welding quality, the sub-shell 9 is operated to rotate intermittently, so that the sub-shell 9 drives the terminal or copper busbar clamped and fixed in it to perform an automatic reversing operation.

[0098] Specifically, in this technical solution, the secondary housing 9 undergoes intermittent rotation operation, according to... Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, the push block 601 is vertically mounted on the welding head 6 in an integrated structure, and is symmetrical about the vertical central axis of the welding head 6. The two push blocks 601 correspond to the second lever 28 on the left clamping mechanism 7 and the second lever 28 on the right clamping mechanism 7, respectively. The second lever 28 has a "Y" shaped structure, consisting of an upper support at the top and two lower supports at the bottom. After the second lever 28 is installed, it is tilted on the main housing 8. The tilting direction of the second lever 28 in the left clamping mechanism 7 is opposite to that in the right clamping mechanism 7. That is, the two second levers 28 are combined to form an "eight" shaped structure. After the two clamping mechanisms 7 slide relative to each other to complete the docking of the terminal and the copper busbar, the upper supports of the two second levers 28 are connected to the two push blocks 601 by pressing.

[0099] Since the end of the push block 601 is rounded and chamfered, the welding head 6 is raised by the second cylinder 5, so that the rounded end of the push block 601 slides against the upper support of the second lever 28. The upper support of the second lever 28 is pushed to move by the pressing action between the push block 601 and the upper support of the second lever 28.

[0100] Because the upper side of the outer wall of the main housing 8 is provided with an integrated connecting seat, a shaft is inserted through the connecting seat and rotated with the assistance of bearings. Also, because the middle part of the second lever 28 is movably locked on the upper connecting seat of the main housing 8 after it is installed, and the shaft of the upper connecting seat of the main housing 8 is inserted into and fixedly connected to the middle of the second lever 28 with bolts, the upper bracket of the second lever 28 is pushed, causing the second lever 28 to flip on the upper connecting seat of the main housing 8.

[0101] Since a spring chamber with the same center as its central column is provided in the upper connecting seat of the main housing 8, a second torsion spring 29 is installed at the flip connection between the second lever 28 and the main housing 8. After the second torsion spring 29 is installed, it is movably sleeved outside the column of the upper connecting seat in the main housing 8 and placed in the spring chamber of the upper connecting seat in the main housing 8. One end of the spring spring 29 is engaged with the wall of the spring chamber, and the other end of the spring spring 29 is engaged with the middle of the second lever 28. After the second lever 28 is driven to flip, the second torsion spring 29 is subjected to force and undergoes elastic deformation.

[0102] Since the front and rear shell walls of the main shell 8 are provided with through grooves that communicate with the circular shell cavity therein, and since the center of the second linkage ring 26 coincides with the center of the main shell 8, the inner ring wall is provided with integrated protrusions on the upper, lower, front and rear four sides, and the outer ring wall is provided with integrated pins on the middle of the front and rear sides, and since the second linkage ring 26 is installed and its protrusions are movably locked in the circular shell cavity of the main shell 8, and the two pins are respectively movably inserted through the two grooves at the outer end of the main shell 8 and extend outward, the second linkage ring 26 is positioned in a movable state within the main shell 8;

[0103] Since the ends of the front and rear pins of the second linkage ring 26 are fixedly engaged with bearings, and since the ends of the two lower supports of the second lever 28 are provided with through grooves, after the second lever 28 and the second linkage ring 26 are assembled, the front and rear pins of the second linkage ring 26, along with the bearings, are respectively movably inserted into the grooves of the two lower supports of the second lever 28, so that the bearings of the pins of the second linkage ring 26 are movably engaged in the grooves of the lower supports of the second lever 28. When the second lever 28 is driven to rotate, the pins of the second linkage ring 26 slide in the lower supports of the second lever 28, and drive the second linkage ring 26 to slide in the circular cavity of the main housing 8.

[0104] Because a spring compartment with the same center is provided on the circular cavity wall of the main housing 8 facing outward, and because a second spring 27 is installed at the sliding connection between the second linkage ring 26 and the main housing 8, the second spring 27 is movably inserted into the spring compartment of the circular cavity in the main housing 8 after being placed. One end of the spring 27 presses against the wall of the spring compartment, and the other end presses against the second linkage ring 26. Furthermore, because the second linkage ring 26 is connected to the transmission ring 32 by a movable sleeve, after the second linkage ring 26 is driven to slide along the outside of the transmission ring 32, the second spring 27 is compressed and undergoes elastic deformation.

[0105] Because the pin 30 has a limiting disc at the tail end, after the pin 30 is installed, the tail end of the pin and the limiting disc are movably inserted into the upper protrusion of the second linkage ring 26, and the head end of the pin moves through the upper protrusion of the second linkage ring 26 and extends outward, so that the pin 30 is positioned on the second linkage ring 26 in a movable state. After the second linkage ring 26 is driven to slide along the outside of the transmission ring 32, it drives the pin 30 to move synchronously.

[0106] Since the annular groove group 33 is concentrically formed on the transmission ring 32, it includes a spiral groove 3301 and a straight groove 3302. The end of the spiral groove 3301 near the pin 30 is the first end, and the end away from the pin 30 is the last end. Similarly, the section of the straight groove 3302 near the pin 30 is the first section, and the section away from the pin 30 is the last section. Since the pin head of the pin 30 is hemispherical, after the pin 30 is installed, the hemispherical pin head is movably inserted into the annular groove group 33, and the two are connected by sliding. In the initial state of the second linkage ring 26, the hemispherical pin head of the pin 30 is placed at the connection between the first end of the spiral groove 3301 and the end of the first section of the straight groove 3302. After the pin 30 slides with the second linkage ring 26, the hemispherical pin head of the pin 30 slides along the spiral groove 3301.

[0107] Since the spiral angle of the spiral groove 3301 is ninety degrees, after the pin 30 slides with the second linkage ring 26, the transmission ring 32 is driven to rotate ninety degrees through the sliding fit between the pin 30 and the spiral groove 3301.

[0108] Since the center of the secondary housing 9 coincides with the center of the primary housing 8, both the inner and outer outer walls of the secondary housing 9 are provided with an integrated limiting ring. The limiting ring is located at the same center as the secondary housing 9, and a bearing is fixedly engaged on the limiting ring. After the secondary housing 9 is installed, it is movably inserted into the circular cavity of the primary housing 8, and the limiting ring, together with the bearing, is movably engaged on the cavity wall of the circular cavity in the primary housing 8. The inner end of the limiting ring moves through the inner cavity opening of the circular cavity in the primary housing 8 and extends outward, and the outer end moves through the outer cavity opening of the circular cavity in the primary housing 8 and extends outward, so that the secondary housing 9 is movably positioned in the primary housing 8.

[0109] Since the center of the transmission ring 32 coincides with the center of the sub-shell 9, after the transmission ring 32 is installed, it is sleeved and fixedly connected to the outward end of the sub-shell 9 by bolts. When the transmission ring 32 is driven, it drives the sub-shell 9 to move synchronously, so that the sub-shell 9 rotates ninety degrees in the circular cavity of the main shell 8, and the sub-shell 9 drives the clamped and fixed terminal or copper busbar to rotate to complete one reversal.

[0110] Based on the above, since the spiral groove 3301 is arranged in a circular array with the annular groove group 33 as the center, there are four spiral grooves 3301. Similarly, the straight groove 3302 is also arranged in a circular array with the annular groove group 33 as the center. Since the straight groove 3302 is placed between two adjacent spiral grooves 3301, the first end of the straight groove 3302 is connected to the first end of the previous spiral groove 3301, and the last end of the straight groove 3302 is connected to the last end of the next spiral groove 3301. When the sub-shell 9 completes one rotation and reversal, the second linkage ring 26 slides along the outside of the transmission ring 32, and the pin 30 slides from the first end of the spiral groove 3301 to the last end of the spiral groove 3301.

[0111] Next, the welding head 6 is lowered by the second cylinder 5, so that the push block 601 loses its pressure on the upper support of the second lever 28. The elastic deformation of the second torsion spring 29 resets the second lever 28 on the upper connecting seat of the main housing 8. The elastic deformation of the second spring 27 resets the second lever 28, causing the second linkage ring 26 to slide in the circular cavity of the main housing 8. After the second linkage ring 26 drives the pin 30 to slide synchronously, the hemispherical head end of the pin 30 slides along the next straight groove 3302 at the connection between the tail end of the spiral groove 3301 and the tail end of the next straight groove 3302. The hemispherical head end of the pin 30 slides to the connection between the first end of the next straight groove 3302 and the first end of the next spiral groove 3301.

[0112] In this cycle, the welding head 6 is operated by the second cylinder 5 to perform reciprocating lifting and lowering motion. Through the pressing action between the push block 601 and the second lever 28, and with the elastic deformation and reset assistance of the second torsion spring 29 and the second spring 27, the second linkage ring 26 is operated to perform reciprocating sliding. Through the sliding cooperation between the pin 30 and the annular groove group 33, the transmission ring 32 is operated to perform intermittent cyclic rotation. That is, the sub-shell 9 drives the clamped and fixed terminals and copper busbars to perform intermittent cyclic rotation with a rotation angle of ninety degrees each time, completing the full-range automatic rotation and reversal of the terminals and copper busbars.

[0113] Meanwhile, in the above technical solutions, according to Figure 14 and Figure 16 As shown, the upper connecting seat of the main housing 8 is provided with an integrated blocking part at the end facing the welding head 6. When the second lever 28 is reset and flipped on the upper connecting seat of the main housing 8, the upper bracket of the second lever 28 presses against the blocking part to prevent the second lever 28 from flipping excessively.

[0114] Meanwhile, in the above technical solutions, according to Figure 15 , Figure 18 and Figure 19 As shown, a third spring 31 is installed at the sliding connection between the pin 30 and the second linkage ring 26. After the third spring 31 is installed, it is movably inserted into the upper protrusion of the second linkage ring 26. One end of the spring 31 presses against the groove wall of the upper protrusion of the second linkage ring 26, and the other end presses against the tail end of the pin 30. With the elastic deformation and reset assistance of the third spring 31, the pin 30 forms an automatic telescopic sliding structure in the upper protrusion of the second linkage ring 26.

[0115] Because the groove depth at the first end of the spiral groove 3301 is greater than the groove depth at the first section of the straight groove 3302, a height difference is formed between the end of the first section of the straight groove 3302 and the first end of the spiral groove 3301. When the pin 30 slides out and is placed at the connection between the first end of the spiral groove 3301 and the end of the first section of the straight groove 3302, the pin 30 slides with the second linkage ring 26. Due to the height difference, the pin 30 is restricted and can only slide along the spiral groove 3301, and will not slide back into the straight groove 3302.

[0116] Meanwhile, in the above technical solutions, according to Figure 15 , Figure 18 and Figure 19As shown, since the groove depths at the beginning and end of the spiral groove 3301 are at the same depth, and the groove depth at the end of the spiral groove 3301 is smaller than the groove depth at the end of the straight groove 3302, a height difference is formed between the end of the end of the straight groove 3302 and the end of the spiral groove 3301. When the pin 30 slides out and is placed at the connection between the end of the spiral groove 3301 and the end of the end of the straight groove 3302, and the pin 30 follows the second linkage ring 26 to reset and slide, the height difference restricts the pin 30, which can only slide along the straight groove 3302 and will not slide back into the spiral groove 3301.

[0117] Meanwhile, in the above technical solutions, according to Figure 15 , Figure 18 and Figure 19 As shown, since the groove depth of the first section of the straight groove 3302 is smaller than that of the last section, a height difference is formed between the first and last sections of the straight groove 3302. Furthermore, since an inclined wall is provided at the height difference between the first and last sections of the straight groove 3302 for transition, when the pin 30 follows the second linkage ring 26 to reset and slide, the pin 30 can slide from the last section of the straight groove 3302, through the inclined wall between the first and last sections of the straight groove 3302, to the first section of the straight groove 3302 through the telescopic sliding cooperation of the pin 30, without affecting the reset sliding of the pin 30 in the straight groove 3302.
