Description

Technical Field

[0001] This invention relates to the field of automotive parts welding, and more particularly to an automotive parts partition welding equipment. Background Technology

[0002] The internal structure of electric vehicle power battery packs and high-voltage electronic control housings generally adopts metal heat insulation partitions and current shunt partitions. The partitions need to be precisely corner-welded and lap-welded to the battery pack housing frame to achieve functions such as cell area separation, thermal isolation, and high-voltage safety protection.

[0003] Welding robots and welding manipulators are the core equipment for realizing automated welding of battery pack shells. At present, industrial welding robots are generally equipped in battery pack shell welding production lines in the industry to replace traditional manual welding. They play an important role in improving production efficiency and ensuring weld consistency. However, in the welding process of separator and shell frame, although the existing welding robots can complete the welding action according to the preset trajectory, the welding quality is highly dependent on the positioning accuracy and clamping stability of the workpiece at the work station. Since the separator is usually a thin-walled metal part, it is easy to generate thermal stress and thermal deformation under the action of welding thermal cycle. When the positioning fixture cannot form a stable constraint on the edge of the separator, even if the welding robot has a precise trajectory, it is difficult to obtain a qualified weld formation effect. The existing welding worktables and fixtures that are used with welding robots only provide simple support and rough positioning. They lack a dedicated limiting and anti-tilting structure arranged along the side of the weld, which cannot form a stable constraint on the edge of the partition. In addition, the clamping mechanism and the limiting mechanism are usually controlled independently. When changing different specifications of the shell, they need to be calibrated separately, which is inefficient, has a large alignment error, and affects the operation accuracy of the welding robot. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing technologies cannot form stable constraints on the edges of partitions, and to propose a welding equipment for automotive parts partitions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A welding equipment for automotive parts separators includes a support frame and a placement box. The placement box is mounted on the support frame and has a battery pack housing frame. The support frame has an installation groove, and a welding robot is installed in the installation groove. The welding robot welds the separator to the battery pack housing frame. The placement box is provided with a placement plate, and a welding worktable that slides inside the placement box is provided relative to the bottom of the placement plate. The welding worktable is provided with a plurality of flexible clamping and pressing components that limit the position of the partition plate. The placement plate is provided with side limiting and anti-tilting components distributed along the side of the weld. The flexible clamping and pressing component includes multiple pairs of connecting rods and limiting clamping plates. Each pair of limiting clamping plates is respectively disposed at the end of each pair of connecting rods. The distance between the two limiting clamping plates and the partition is adjusted by moving each pair of connecting rods in opposite directions. The side limiting anti-tilting component includes a mounting plate, a first pressing plate, and a second pressing plate. The bottom end of the mounting plate is provided with multiple pairs of mounting platforms. The first pressing plate and the second pressing plate are mounted on the mounting platforms and are respectively attached to the battery pack housing frame and the partition to limit the relative position of the battery pack housing frame and the partition.

[0006] Preferably, the bottom end of the mounting plate is provided with a driving component, which drives each pair of mounting platforms to move towards or in opposite directions. The driving component includes an electric guide rail and an electric slider disposed at the bottom of the mounting plate. The electric slider is slidably disposed on the electric guide rail, and the mounting platform is disposed on the electric slider. The two clamping plates are pressed against both sides of the partition by the electric slider sliding on the electric guide rail.

[0007] Preferably, the placement plate is provided with an electric guide rail and an electric slider. The electric slider is provided with an installation frame. A movable frame is slidably arranged inside the installation frame. An installation frame is fixedly installed at the bottom of the movable frame. The installation plate is slidably arranged at the bottom of the installation frame. An electric telescopic rod is provided on the movable frame. By sliding the installation frame on the placement plate and extending and retracting the electric telescopic rod, the clamping plate is pressed against the inner wall of the battery pack housing frame.

[0008] Preferably, the welding worktable is provided with two oppositely arranged mounting frames, and multiple sliding frames are slidably arranged in each of the two mounting frames. A rotating rod is commonly arranged in the multiple sliding frames, and both ends of the rotating rod are rotatably arranged in the mounting frames. The rotating rod is driven to rotate by a drive motor.

[0009] Preferably, a bidirectional lead screw is provided inside the sliding frame, a guide hole is provided inside the bidirectional lead screw, and a rotating rod is disposed inside the guide hole. The connecting rod is slidably disposed inside the sliding frame and sleeved on the bidirectional lead screw. The connecting rod and the bidirectional lead screw are connected by threads.

[0010] Preferably, the mounting frame has multiple sliding holes, and the welding worktable has sliding grooves corresponding to the multiple sliding holes. Each of the multiple sliding holes and sliding grooves has a linkage rod, and the linkage rod is fixedly connected to the sliding frame.

[0011] Preferably, the placement box has multiple movable holes on both sides, the linkage rod is slidably disposed in the movable holes, and the other end of the linkage rod is fixedly connected to the mounting plate.

[0012] Preferably, the welding workbench is provided with an electromagnetic guide rail, and a telescopic sliding plate is provided inside the electromagnetic guide rail. A sliding hole is opened on the side end of the mounting frame, and the telescopic sliding plate is slidably disposed in the sliding hole and fixedly connected to the side end of the sliding frame.

[0013] Preferably, the placement box is equipped with an electric lifting rod, the other end of which is fixedly connected to the welding workbench. The placement plate is equipped with multiple limiting plates, which are used to position the battery pack housing frame by contacting the outer wall of the battery pack housing frame.

[0014] Preferably, the welding worktable is provided with multiple electric push rods, which push the mounting frame to slide on the welding worktable by extending and retracting the electric push rods, and the linkage rod is located at the lower part of the electric push rods.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention forms a stable lateral constraint on the edge of the partition by setting a second clamping plate distributed along the side of the weld and a first clamping plate that is close to the inner wall of the shell, which effectively counteracts the warping and lateral displacement of the partition caused by the welding thermal cycle, ensures a constant weld gap, and significantly improves the quality of fillet welds and lap welds.

[0016] 2. The present invention uses a linkage rod to drive the flexible clamping and pressing component and the side limiting anti-tilting component. When the spacing of the limiting clamping plates is adjusted to adapt to different partition widths, the second pressing plate automatically and synchronously moves to the corresponding weld side position, eliminating the need for manual secondary calibration and greatly shortening the adjustment time when switching between various battery pack shell specifications.

[0017] 3. This invention uses a bidirectional lead screw to drive a pair of connecting rods and a limiting clamping plate to move in opposite directions, and works with a high-temperature resistant elastic pad to achieve flexible clamping, avoiding damage to the surface of the partition. Combined with the lifting of the welding worktable, the multi-dimensional adjustment of the electromagnetic guide rail and the electric push rod, it can quickly adapt to battery pack shells of different sizes and different compartment layouts.

[0020] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figures 1-11 A welding equipment for automotive parts separators is used to weld and fix the metal heat insulation or shunt separators inside the battery pack of an electric vehicle to the inside of the battery pack shell frame 7, so as to achieve fillet welding and lap welding between the separator and the shell frame. The equipment includes a support frame plate 1, a placement box 4, a welding robot 3, a welding workbench 8, a flexible clamping and pressing assembly, and a side limiting and anti-tilting assembly. like Figure 1As shown, the support frame 1 is the base for supporting the entire equipment. It is made of rectangular steel plate or cast iron platform. Its lower surface is equipped with vibration damping pads, and its upper surface is used to fix the placement box 4 and welding robot 3. The support frame 1 is fixedly provided with a mounting groove 2, which is a recessed rectangular groove. Its size matches the base of the welding robot 3. The welding robot 3 is fixedly installed in the mounting groove 2 by bolts. The welding gun end of the welding robot 3 faces the welding area inside the placement box 4. It is used to perform automated welding operations at the docking position of the separator and the battery pack shell frame 7. The welding robot 3 can be a six-axis articulated industrial robot. Its end is equipped with a laser weld seam tracking sensor for real-time adjustment of the welding gun trajectory.

[0022] The placement box 4 is fixedly installed on the upper end of the support frame plate 1. The placement box 4 is a rectangular box structure with an opening at the top. The placement plate 5 is fixedly installed on the upper end of the placement box 4 by bolts. The placement plate 5 is used to support and position the battery pack housing frame 7. Multiple sets of limiting plates 6 are installed on the placement plate 5. The limiting plates 6 are evenly distributed along the outer periphery of the battery pack housing frame 7. The limiting plates 6 can be pneumatically or electrically driven. Specifically, in this embodiment, multiple miniature cylinders or electric push rods are fixedly installed on the placement plate 5, and their telescopic ends are fixedly connected to the limiting plates 6. The inner side of the limiting plates 6 is covered with rubber or polyurethane pads. When the battery pack housing frame 7 is placed on the placement plate 5, the limiting plates 6 are pushed towards the center by the multiple miniature cylinders or electric push rods, so that the inner sidewall of the limiting plates 6 is tightly fitted with the outer wall of the battery pack housing frame 7, realizing the rapid positioning of the outer periphery of the battery pack housing frame 7 and avoiding the overall displacement of the housing during the welding process. The stroke of the limiting plates 6 can be adjusted according to different housing sizes by using limiting sensors or mechanical stops.

[0023] like Figure 3 As shown, a welding workbench 8 is provided inside the placement box 4 and below the placement plate 5. The welding workbench 8 is a rectangular flat plate structure with guide sliders at its four corners, which slide in cooperation with the vertical guide rails provided on the inner wall of the placement box 4 to ensure smooth lifting. An electric lifting rod 801 is fixedly installed on the bottom wall inside the placement box 4. The electric lifting rod 801 adopts a multi-stage telescopic electric cylinder or ball screw jack. Its telescopic end faces upward and is fixedly connected to the bottom of the welding workbench 8. There are four electric lifting rods 801, which are arranged at the four corners of the welding workbench 8. The synchronous lifting of the four rods is ensured by a synchronous controller. The telescopic drive of the electric lifting rod 801 realizes the vertical movement of the welding workbench 8 inside the placement box 4. The sliding position of the welding workbench 8 inside the placement box 4 is determined according to the height of the battery pack shell.

[0024] like Figure 6As shown, when the welding worktable 8 rises, the flexible clamping and pressing assembly is raised above the placement plate 5, so that the limiting clamping plate 906 extends into the battery pack housing frame 7 and clamps the partition. After welding is completed, the welding worktable 8 descends and resets, making it easier to remove the workpiece and load it for the next time.

[0025] like Figure 4 As shown, the upper surface of the welding workbench 8 is provided with an electromagnetic guide rail 802. The electromagnetic guide rail 802 is a linear guide rail structure, with an electromagnetic coil and a permanent magnet embedded inside, which can generate a controllable electromagnetic attraction force. A telescopic sliding plate 803 is installed inside the electromagnetic guide rail 802. The telescopic sliding plate 803 is made of a high magnetic permeability material. Its bottom forms a magnetic levitation or magnetic attraction sliding fit with the electromagnetic guide rail 802. The telescopic sliding plate 803 can slide and be positioned along the length direction inside the electromagnetic guide rail 802. Its sliding position is controlled by the energizing phase sequence and current magnitude of the electromagnetic guide rail 802. The telescopic sliding plate 803 is used to adjust the spacing between adjacent sliding frames 901 within the same mounting frame 9.

[0026] like Figure 8 As shown, multiple electric push rods 804 are also fixedly installed on the upper end of the welding worktable 8. The electric push rods 804 are miniature DC electric push rods. The telescopic end of the electric push rod 804 is fixedly connected to the side wall of the mounting frame 9. By telescoping the electric push rod 804, the mounting frame 9 is pushed to move horizontally on the welding worktable 8 to achieve coarse adjustment of the clamping position.

[0027] Multiple sliding frames 901 are slidably installed inside the mounting frame 9. The sliding frames 901 can slide independently along the length of the mounting frame 9 to adapt to the clamping requirements of partitions with unequal distances. In order to achieve independent sliding of each sliding frame 901, this embodiment provides an independent micro linear drive component at the side or bottom of each sliding frame 901. Specifically, the micro linear drive component adopts a lead screw module driven by a micro stepper motor: a precision lead screw is arranged along the length of the sliding groove in the mounting frame 9, and each sliding frame 901 is provided with a nut that meshes with the lead screw. Furthermore, each sliding frame 901 has an independent clutch between the nut and the lead screw or adopts a segmented lead screw structure.

[0028] like Figure 6As shown, each sliding frame 901 is equipped with a bidirectional lead screw 902. The bidirectional lead screw 902 is a lead screw with left and right threaded sections, and its middle section is a smooth shaft. An axial guide hole is opened in the center of the smooth shaft. The guide hole is hexagonal or splined. A rotating rod 903 is passed through multiple sliding frames 901. The cross-sectional shape of the rotating rod 903 matches the guide hole (such as a hexagonal bar or splined shaft). The rotating rod 903 is clearance-fitted in the guide hole, which can transmit torque and allow the bidirectional lead screw 902 to slide freely along the axial direction of the rotating rod 903. The two ends of the rotating rod 903 are rotatably set in the bearing seats at the end of the mounting frame 9. A drive motor 904 is fixedly installed at one end of the mounting frame 9. The drive motor 904 is a servo motor or a stepper motor. Its output shaft is fixedly connected to the rotating rod 903 through a coupling, driving the rotating rod 903 to rotate.

[0029] like Figure 11 As shown, when the rotating rod 903 rotates, it synchronously drives all the bidirectional lead screws 902 to rotate in the same direction. A pair of connecting rods 905 are threadedly connected to the bidirectional lead screws 902. The two connecting rods 905 are arranged symmetrically with the center line of the lead screw. The lower part of the connecting rod 905 is provided with a nut hole that mates with the thread of the bidirectional lead screw 902. The side of the connecting rod 905 slides and is limited by the guide groove on the inner wall of the sliding frame 901 to prevent the connecting rod 905 from rotating with the lead screw. The upper end of the connecting rod 905 extends out from the top opening of the sliding frame 901 and is fixedly connected to the limit clamping plate 906.

[0030] like Figure 11 As shown, when the drive motor 904 drives the rotating rod 903 and the bidirectional lead screw 902 to rotate, a pair of connecting rods 905 move towards each other or away from each other, causing the limiting clamping plate 906 to clamp or loosen the partition. The inner side of the limiting clamping plate 906 is attached with a high-temperature resistant elastic pad to achieve flexible clamping, avoid damage or deformation of the partition surface, and ensure stable clamping.

[0031] like Figure 11 As shown, the side wall of the mounting frame 9 has a sliding hole 907. The end of the telescopic sliding plate 803 passes through the sliding hole 907 and is fixed to the sliding frame 901. The distance between the sliding frame 901 is infinitely adjustable through the electromagnetic guide rail 802 and the telescopic sliding plate 803, which can adapt to the multi-specification separators of different brands and sizes of battery packs. like Figure 3 and 10 As shown, a side-limiting anti-tilting assembly is provided above the placement plate 5, including a mounting plate 1001, a first pressing plate 1002, a second pressing plate 1003, a movable frame 1004, an electric telescopic rod 1005, and a mounting frame 1006.

[0032] The placement plate 5 is equipped with an electric guide rail 2 and an electric slider 2. The electric slider 2 is fixedly mounted with a mounting frame 1006, which allows the mounting frame 1006 to move laterally along the placement plate 5. A movable frame 1004 is slidably mounted inside the mounting frame 1006. An electric telescopic rod 1005 is fixedly mounted on the movable frame 1004. The telescopic end of the electric telescopic rod 1005 pushes the movable frame 1004 to slide up and down inside the mounting frame 1006.

[0033] A mounting bracket is fixedly installed at the bottom of the movable frame 1004. The mounting plate 1001 is horizontally slidably installed at the bottom of the mounting bracket. The bottom of the mounting plate 1001 is provided with an electric guide rail and an electric slider. The lower end of the electric slider is fixed to a mounting platform. A first clamping plate 1002 and a second clamping plate 1003 are fixed on the mounting platform respectively. The first clamping plate 1002 is used to press against the inner wall of the battery pack housing frame 7 to counteract the clamping force of the external limiting plate 6 and balance the force on the housing. The second clamping plate 1003 is arranged along the side of the weld seam of the partition, close to the edge of the partition, to suppress welding heat deformation and edge warping. The first electric slider can drive the second clamping plate 1003 to move towards each other, fitting the weld seam positions on both sides of the partition to achieve weld seam area limitation.

[0034] like Figure 7 As shown, the mounting frame 9 has multiple sliding holes 908, and the welding workbench 8 has a sliding groove 805. A linkage rod 10 is inserted through both the sliding holes 908 and the sliding groove 805. One end of the linkage rod 10 is fixed to the sliding frame 901, and the other end passes through the moving hole 11 on the side wall of the placement box 4 and is fixed to the mounting plate 1001.

[0035] like Figure 10 As shown, the linkage 10 has an overall L-shaped structure, consisting of an L-shaped mounting sleeve and two moving rods. The two moving rods are slidably set inside the mounting sleeve, so that the linkage 10 can adaptively match the lifting stroke of the welding workbench 8 and the lateral displacement of the mounting frame 1006, and always maintain continuous transmission, no jamming, and no misalignment during multi-dimensional adjustment.

[0036] When the sliding frame 901 adjusts the spacing with the telescopic sliding plate 803, the linkage rod 10 is synchronously driven with the sliding frame 901, driving the mounting plate 1001, the first clamping plate 1002 and the second clamping plate 1003 to achieve linkage displacement along the same trajectory and at the same distance, so that the flexible clamping center position of the partition plate always corresponds to the side limit position of the weld, without the need for manual secondary calibration and adjustment. Through the above-mentioned linkage constraint, the clamping plate 1003 can always provide lateral clamping constraint along the edge of the separator weld. Under the action of high welding temperature, it can effectively offset the internal stress of the separator caused by thermal expansion and contraction, reduce the warping, lateral displacement and overall twisting trend of the separator weld area, and ensure that the weld gap between the separator and the battery pack housing frame 7 remains constant.

[0037] It should be noted that the models, power, stroke, and control parameters of electrical components such as the drive motor 904, electric guide rail one, electric guide rail two, electric telescopic rod 1005, electromagnetic guide rail 802, electric lifting rod 801, and electric push rod 804 in this embodiment, as well as the specific specifications such as clamping force and limiting preload required for preventing edge warping and displacement during separator welding, need to be selected and determined based on the actual structural dimensions of the device, the material thickness of the battery pack shell frame 7 and the separator, the amount of welding thermal deformation, and other actual working conditions. The specific selection and calculation methods adopt existing technologies in this field, so they will not be elaborated here.

[0038] The functional principle of this invention can be explained through the following operational methods: Place the battery pack housing frame 7 on the placement plate 5, activate the limiting plate 6, so that the limiting plate 6 hugs the outer wall of the battery pack housing frame 7 from all sides, and complete the outer periphery positioning of the battery pack housing frame 7. The electric lifting rod 801 extends and pushes the welding worktable 8 upward, so that the limiting clamping plate 906 enters the battery pack housing frame 7 and reaches the partition clamping height; When the drive motor 904 starts, it drives the rotating rod 903 and the bidirectional lead screw 902 to rotate, causing a pair of connecting rods 905 to move towards each other. The limiting clamping plate 906 flexibly clamps the partition from both sides to prevent the partition from shifting. For battery packs of different sizes, the electromagnetic guide rail 802 drives the telescopic sliding plate 803 to move, adjusting the distance between the sliding frame 901 and the limiting clamping plate 906. At the same time, the linkage rod 10 synchronously drives the mounting plate 1001 to move, so that the pressure plate 1003 and the weld position of the partition plate are automatically aligned. The electric telescopic rod 1005 pushes the moving frame 1004 and the mounting plate 1001 close to the battery pack housing frame 7. The first clamping plate 1002 is pressed against the inner wall of the battery pack housing frame 7 to balance the external clamping force. The first electric guide rail drives the second clamping plate 1003 to press against the side of the weld seam of the partition to form edge constraint and suppress welding thermal warping. Welding robot 3 starts and performs precision fillet welding and lap welding along the butt joint gap between the partition and the battery pack shell frame 7. The weld area is limited by clamping plate 2 1003 and clamping plate 1 1002 to keep the welding gap constant and the weld formation uniform. After welding is completed, the drive motor 904 reverses to release the limit clamping plate 906, the electric telescopic rod 1005 retracts, the clamping plate 1002 and clamping plate 2 1003 are separated from the workpiece, the electric lifting rod 801 drives the welding worktable 8 to descend, the limit plate 6 is released, the welded battery pack housing assembly is taken out, and the equipment is reset to enter the next cycle.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
