Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a rivet welding device and method for the production of new energy storage cabinets. Background Technology

[0002] New energy storage cabinets are devices that integrate battery systems, electrical control, thermal management and monitoring technologies. They achieve power supply and demand balance by efficiently storing and releasing electrical energy. Their core functions include peak shaving and valley filling, emergency backup, new energy consumption and microgrid support, which can significantly improve energy utilization efficiency and ensure power supply stability.

[0003] The outer shell of new energy storage cabinets is usually assembled and fixed with steel plates and rivets and bolts. However, some companies have high requirements for the appearance quality of energy storage cabinets and do not allow protruding rivets on the surface. Therefore, rivets cannot penetrate the steel plate for installation and can only be welded to the inside. Therefore, welding equipment for rivets is required. Because rivets are small and require precise assembly, robotic arms are often used for accurate clamping and placement. For example, CN112388656B discloses an automatic assembly mechanism for wire-drawing rivets using a robotic arm, belonging to the field of automated riveting equipment technology. This invention addresses the technical problems of low assembly efficiency and poor riveting quality in existing wire-drawing rivet systems. The invention includes a robotic arm, a rivet assembly mechanism, and an industrial camera. The rivet assembly mechanism is mounted at the end of the robotic arm, and the industrial camera is fixed to the rivet assembly mechanism. The wire-drawing rivets are placed in a rivet tray. The rivet assembly mechanism includes a base, a protective shell, a vertical cylinder, and a clamping mechanism. The protective shell is detachably connected to the base, and the vertical cylinder is bolted to the protective shell. A piston is slidably mounted on the lower part of the vertical cylinder, and the clamping mechanism is fixed to the lower end of the piston. A positioning hole is provided at the bottom of the protective shell. The clamping mechanism includes a fixed gripper and a movable gripper.

[0004] The above technology is used for rivet assembly, employing practical robotic arms. Robotic arms are also frequently used for precise welding movements, leading to higher costs. Currently, for assembling rivets and other fasteners, vibratory feeders are often used to sort the rivets and output them from one end. Clamping devices, such as robotic arms or three-axis motion modules, work with grippers to hold the rivets one by one from the output end. The advantage is that the position is fixed, and the grippers move to a designated point to pick up the rivets each time. However, when moving rivets to different positions on a large steel plate for welding, the overall travel distance from a fixed point is long, reducing work efficiency. Furthermore, if using three-axis motion modules, the longer travel distance can increase deformation errors and affect accuracy. Summary of the Invention

[0011] Preferably, an adjustable fixing component is rotatably connected to the tabletop. One end of the adjustable fixing component is rotatably connected to the tabletop and the new energy storage cabinet steel plate is fixed by a diagonal clamping method. Fixed support blocks are fixedly connected to the top of the tabletop at the other two diagonal corners of the steel plate for support. Several flip support blocks are rotatably connected to the top of the tabletop and on both sides of the adjustable fixing component by torsion springs. A storage groove for storing the flip support blocks is opened on the tabletop. When the adjustable fixing component rotates to pass the flip support blocks, it pushes the flip support blocks into the storage groove.

[0012] Preferably, the adjustable fastener includes: The upper shell has a bottom cover fixedly connected to its bottom by bolts; A positioning shaft passes through one end of the upper shell and the bottom cover, as well as the table surface, and is locked at the bottom end by a snap ring. A fixed angle plate is fixedly connected to the top of the positioning shaft to position one corner of the steel plate. An anti-slip structure is provided at the bottom end of the bottom cover away from the positioning shaft. A lead screw is rotatably connected inside the upper housing. A drive shaft is rotatably connected to the top of the upper housing at the end away from the positioning shaft.

[0013] Preferably, the positioning structure includes a threaded sleeve threaded onto a lead screw, and a U-shaped frame is fixedly connected to the bottom of the threaded sleeve.

[0014] Preferably, the vibratory feeder is mounted on one side of the processing table via a machine frame, and a control panel is also installed on the machine frame. The control panel is connected to and controls other electronic devices via wires.

[0015] This invention also discloses a method for using a riveting welding device in the production of new energy storage cabinets, comprising the following steps: Step 1: Insert rivets into the vibratory feeder and fix the steel plate of the new energy storage cabinet on the table. Step 2: Use a vibratory feeder to evenly distribute the rivets onto the transition track, making the rivets vertical and move to the right on the transition track. When they move onto the arrangement track, use the intermittently activated flipping structure to push the rivets upward, causing them to deflect to a horizontal position, and then push the rivets to the right. Step 3: Activate the three-axis moving module to move the clamping and welding structure, and clamp the rivets on the clamping and welding structure. Then place the rivets on the steel plate, and weld the rivets and the steel plate. After the required rivet welding is completed, stop the machine and remove the steel plate.

[0016] This invention provides a riveting welding device and method for the production of new energy storage cabinets. Compared with the prior art, it has the following advantages: 1. This rivet welding equipment for the production of new energy storage cabinets, through the cooperation of a vibratory feeder, a transition track, and an arrangement track, can output rivets in an orderly manner and maintain their horizontal alignment. Due to the influence of the rivet structure, it is relatively easy to initially arrange them vertically on the transition track. To facilitate the removal of rivets from the welding structure, a flipping structure is set to push the vertical rivets to a horizontal position. In addition, to maintain the neatness of the rivets, a wave-shaped positioning groove is set on the arrangement track to position the rivets, thereby ensuring accurate rivet positioning. The flipping structure also has the function of pushing the rivets to the right while flipping them, allowing the rivets to smoothly pass over the crests of the positioning grooves. The linkage operation is convenient. Furthermore, the front of the arrangement track is fully open, allowing the welding structure to remove rivets from any position without having to clamp them at the end. This reduces the stroke of the three-axis moving module driving the welding structure, thereby improving efficiency and reducing errors.

[0017] 2. This rivet welding equipment for the production of new energy storage cabinets features a clamping welding structure. The clamping components are designed to hold the rivets in a flip-up manner. When rotated upwards to a horizontal position, the sleeve can support the rivet shaft from bottom to top. The repulsive force of the magnet pushes out the sliding tube, which then simultaneously locks the rivet shaft and uses the friction of the damping block to lock it in place. The rivet can then be lifted and moved. The structure is simple and easy to operate, significantly reducing costs compared to current precise robotic arm clamping. Furthermore, the clamping welding structure integrates welding guns, with four sets of welding guns arranged in an array. During descent, all four sides of the rivet head can be welded simultaneously, resulting in high welding efficiency. Since multi-point welding does not require moving the welding guns, only a welding gun holder is needed for fixed installation, eliminating the need for a robotic arm for clamping.

[0018] 3. This riveting and welding equipment for the production of new energy storage cabinets uses adjustable fasteners to fix steel plates. One end of the adjustable fastener has a fixed angle plate, while the other end has a movable angle plate. The entire adjustable fastener is rotatable, allowing it to adapt to steel plates of different lengths and widths for welding. It can also keep one corner of the steel plate in a fixed position, which can be used as the origin to determine the position of the rivet to be welded. The adjustable fastener can be stabilized on the table using friction, and is flexible in adjustment. To maintain the stability of the steel plate, a multi-point support system is used, consisting of a flip support block and a fixed support block. To avoid affecting the rotation of the adjustable fastener, the flip support block is designed to be flipped and stored inside the table. When rotating the adjustable fastener, the obstructing flip support block can be pushed directly into the table. After passing over it, the flip support block can be reset to continue supporting, thus ensuring that the steel plate is stably supported. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] See Figures 1-14 This invention discloses a riveting welding device for the production of new energy storage cabinets, and provides the following three technical solutions: Figures 1-6 The first embodiment is shown: it includes a processing table 1, the steel plate of the new energy storage cabinet is fixed to the table surface 11 of the processing table 1 by welding rivets, a three-axis moving module 8 is installed on the table surface 11 by a support frame 10, and a clamping welding structure 9 is installed on the slide of the Z-axis moving module of the three-axis moving module 8, and also includes: Vibratory feeder 3 is set on one side of processing table 1 and is used to output rivets in an orderly manner. Vibratory feeder 3 is mounted on one side of processing table 1 by machine base 2. Machine base 2 is also equipped with control panel. Control panel is connected to and controls other electronic equipment through wires. The wire routing is relatively messy and is not shown. The wires should run inside processing table 1 as much as possible. For the wires on the three-axis moving module 8, tank chains are used for protection. The arrangement track 6 is fixedly connected to the rear side of the top of the table 11 by the first bracket 5. It is used to arrange rivets horizontally, and any horizontally placed rivets on the arrangement track 6 can be taken out and welded. The transition track 4 has its left end not in contact with the discharge end of the vibrating plate 3, so that the transition track 4 is not affected by the vibration of the vibrating plate 3. The right end is fixedly connected to the arrangement track 6, which is used to vertically arrange and transmit the rivets. The flip structure 7 is fixedly connected to the top of the table 11 and located below the left end of the arrangement track 6. The vertical rivet is pushed to the horizontal by the upward push and the horizontal rivet is pushed to the right. The flipping structure 7 includes an electric push rod 72 fixedly connected to the top of the table 11 via a second bracket 71. A U-shaped push frame 73 is fixedly connected to the top of the electric push rod 72. A trapezoidal push block 74 is longitudinally elastically slidable on the inner side of the U-shaped push frame 73. The trapezoidal push block 74 first contacts the rivet and pushes it to the lateral direction before stopping. The U-shaped push frame 73 then contacts the rivet and pushes it to the right. The top of the U-shaped push frame 73 has a rightward inclined surface, and the top of the trapezoidal push block 74 has a backward inclined surface. A limit strip 75 is fixedly connected to the bottom of one side of the trapezoidal push block 74 to limit the extreme height of the trapezoidal push block 74. A guide rod 76 is fixedly connected to the bottom of the inner side of the U-shaped push frame 73, which slides into the trapezoidal push block 74. A spring 77 is sleeved on the guide rod 76 at the bottom of the trapezoidal push block 74.

[0023] The transition track 4 has a U-shaped cross section, and a rivet shaft groove 41 corresponding to the rivet shaft is provided on the bottom inner side; The arrangement track 6 includes an entrance positioning track 61 that is plugged into the transition track 4 at its left end and fixed with bolts. A U-shaped flip track 62 for flipping the rivet shaft is provided on the right side of the entrance positioning track 61. A rivet shaft positioning track 63 for supporting the rivet shaft is fixedly connected to the right end of the entrance positioning track 61. Several positioning grooves 64 are provided on the top of the rivet shaft positioning track 63 to separate and position the rivet shaft. The rivet shaft is located at the lowest point of the positioning groove 64 under its own weight, thus maintaining accurate positioning. A rivet head limiting baffle 65 is fixedly connected to the rear side of the entrance positioning track 61 to limit the rear side of the rivet head. A gap is reserved between the rivet head limiting baffle 65 and the rivet shaft positioning track 63 for the rivet head to slide. A pressure plate 66 extends and bends from the top of the rivet head limiting baffle 65 and the position opposite to the U-shaped flip track 62 to limit the upward movement of the rivet head at that position.

[0024] By using the vibratory feeder 3, transition track 4, and arrangement track 6 in combination, rivets can be output in an orderly manner and kept horizontally arranged. Due to the influence of the rivet structure, it is easier to arrange them vertically on the transition track 4 during the initial arrangement. In order to facilitate the removal of rivets from the clamping welding structure 9, a flipping structure 7 is set to push the vertical rivets to a horizontal state. In order to keep the rivets neat, a wave-shaped positioning groove 64 is set on the arrangement track 6 to position the rivets, thereby making the rivet position accurate. The flipping structure 7 also has the function of pushing the rivets to the right while flipping them, so that the rivets can smoothly pass over the crest of the positioning groove 64. The linkage operation is convenient. Furthermore, the front of the arrangement track 6 is fully open, so that the clamping welding structure 9 can remove the rivets at any position without having to clamp them at the end. This reduces the stroke of the three-axis moving module 8 driving the clamping welding structure 9, thereby improving efficiency and reducing errors.

[0025] Figures 7-9 The second embodiment is shown, and its main difference from the first embodiment is that the clamping welding structure 9 includes: Mounting bracket 91 is fixedly connected to the slide of the Z-axis moving module by bolts; Hollow brackets 92 are fixedly connected in pairs to the bottom sides of mounting brackets 91 by bolts; The clamping part 93 is rotatably connected to the bottom between a pair of hollow brackets 92. After rotating to a horizontal position, it clamps the rivet shaft, flips upward to lift the rivet, and then moves to the position to be welded and lowers it vertically. Servo motor 94 is fixedly connected to the bottom of mounting bracket 91 and is used to drive clamp 93 to rotate; The transmission belt mechanism 95 is located inside the hollow bracket 92 on one side and is used to connect the output end of the servo motor 94 and the clamping member 93. The welding torch holder 97 is sleeved on the outside of the two hollow brackets 92 and fixed with bolts; The welding torch 98 is fixed at the four corners of the welding torch holder 97, and the welding end of the welding torch 98 points to the edge of the rivet head to be welded for multi-point synchronous welding. An industrial camera 99 is fixedly connected to a mounting bracket 91 and tilted downwards and backwards to take pictures.

[0026] Clamping member 93 includes: Rotary seat 931, both sides of which are rotatably connected to hollow bracket 92 via fixedly connected rotating shafts 939; Sleeve 933 is fixedly connected to the bottom center of rotating seat 931. Half of the lower half of the side of sleeve 933 is cut into a flat notch 934 to support the rivet shaft upward. The sliding tube 936 is slidably sleeved outside the sleeve 933 and covers the flat notch 934 by axial sliding. The inner bottom end of the sliding tube 936 is fixedly connected to a damping block 938 for pressing and fixing the rivet shaft. Electromagnet 932 is fixedly connected to the bottom of rotating base 931; The permanent magnet 937 is fixedly sleeved on the outside of the top end of the sliding tube 936; A conical spring 935 is fixedly connected to the bottom of the rotating seat 931 and located inside the sleeve 933; A plug 9310 is provided through the center of one end of the rotating shaft 939, and a brush-type power supply socket 96 is fixedly connected through the outer wall of the hollow bracket 92 on the corresponding side. The plug 9310 and the brush-type power supply socket 96 are electrically connected by insertion and are powered by the brush to maintain rotation.

[0027] The clamping and welding structure 9 provided in this application clamps the rivet using a clamping member 93. The clamping member 93 is configured to flip, so that when rotated upwards to a horizontal position, the sleeve 933 can hold the rivet shaft from bottom to top. After the sliding tube 936 is pushed out by the repulsive force of the magnet, it can both lock the rivet shaft and lock the rivet shaft using the friction of the damping block 938. Then the rivet can be lifted and moved. The structure is simple and easy to operate. Compared with the current precise robotic arm clamping, the cost is greatly reduced. At the same time, the clamping and welding structure 9 integrates a welding gun 98. The four sets of welding guns 98 are arranged in an array. When descending, they can weld the four sides of the rivet head at the same time, which is highly efficient. Since there is no need to move the welding gun 98 for multi-point welding, only the welding gun fixing bracket 97 is needed for fixed installation, and there is no need to use a robotic arm for clamping operation.

[0028] Figures 10-14 The third embodiment is shown. The main difference from the first embodiment is that an adjustable fixing member 15 is rotatably connected to the platform 11. One end of the adjustable fixing member 15 is rotatably connected to the platform 11 and the new energy storage cabinet steel plate is fixed by a diagonal clamping method. Fixed support blocks 12 are fixedly connected to the top of the platform 11 at the other two diagonal corners of the steel plate for support. Several flip support blocks 13 are rotatably connected to the top of the platform 11 and the area on both sides of the adjustable fixing member 15 by torsion springs 16. A storage groove 14 for storing the flip support blocks 13 is opened on the platform 11. When the adjustable fixing member 15 rotates to pass the flip support blocks 13, it pushes the flip support blocks 13 into the storage groove 14.

[0029] Adjustable fastener 15 includes: The upper shell 151 has a bottom cover 152 fixedly connected to its bottom by bolts. The positioning shaft 153 passes through one end of the upper shell 151 and the bottom cover 152 and the table 11, and is locked at the bottom end by a snap ring 154. The top end of the positioning shaft 153 is fixedly connected to a fixed angle plate 155 to position one corner of the steel plate. The bottom end of the bottom cover 152 away from the positioning shaft 153 is provided with an anti-slip structure. The lead screw 1511 is rotatably connected inside the upper shell 151. The top of the upper shell 151 away from the positioning shaft 153 is rotatably connected to the drive shaft 1513. The bottom end of the drive shaft 1513 and one end of the lead screw 1511 are driven by a bevel gear set 1512. The top end of the drive shaft 1513 is also fitted with a rocker handle 1514. The lead screw 1511 is threaded with a positioning structure at the other opposite corner of the positioning steel plate.

[0030] The positioning structure includes a threaded sleeve 156 threaded onto a lead screw 1511, with a U-shaped bracket 157 fixedly connected to the bottom of the threaded sleeve 156. The U-shaped bracket 157 extends through both sides to the outside of the upper shell 151, and a sliding plate 158 is bolted to the top of the U-shaped bracket 157. The upper shell 151 has notches on both sides for the U-shaped bracket 157 to pass through. By allowing the U-shaped bracket 157 to pass through from both sides rather than directly from the top, the problem of welding slag potentially splashing onto the lead screw 151 during welding, which could occur due to the slot at the top of the upper shell 151, can be avoided. The inner side of the movable plate 158 is rotatably connected to the movable fixed angle plate 1510 through the limiting rotation groove 159. The limiting rotation groove 159 maintains the rotation function of the movable fixed angle plate 1510 on the one hand, and prevents the movable fixed angle plate 1510 from flipping up due to excessive squeezing force on the other hand. Right angle grooves are opened on the opposite surfaces of the fixed fixed angle plate 155 and the movable fixed angle plate 1510 to clamp the right angle corner of the positioning steel plate. The bottom surface of the right angle groove of the fixed fixed angle plate 155, the bottom surface of the limiting rotation groove 159 of the sliding plate 158, and the top surface of the flipping support block 13 and the fixed support block 12 are at the same height.

[0031] This application uses an adjustable fixing component 15 to fix the steel plate. One end of the adjustable fixing component 15 has a fixed angle plate 155, while the other end has a movable angle plate 1510, which is movable. The adjustable fixing component 15 is rotatable, thus adapting to steel plates of different lengths and widths for welding. It can also keep one corner of the steel plate in a fixed position, so this point can be used as the origin to determine the position of the rivet to be welded. The adjustable fixing component 15 can be stabilized on the table surface 11 by friction, and is flexible in adjustment. In order to maintain the stability of the steel plate, a multi-point support is used in conjunction with a flip support block 13 and a fixed support block 12. In order not to affect the rotation of the adjustable fixing component 15, the flip support block 13 is set to be flipped and stored in the table surface 11. When rotating the adjustable fixing component 15, the obstructing flip support block 13 can be directly pushed into the table surface 11. After passing over it, the flip support block 13 can be reset to continue supporting, thus ensuring that the steel plate can be stably supported.

[0032] This invention also discloses a method for using a riveting welding device in the production of new energy storage cabinets, comprising the following steps: Step 1: Insert rivets into the vibratory feeder 3 and fix the steel plate of the new energy storage cabinet on the table 11. When fixing, first place the steel plate on the fixed support block 12, the flip support block 13, and the adjustable fixing component 15. Then adjust the angle of the adjustable fixing component 15 to keep it aligned with the diagonal of the steel plate. When rotating the adjustable fixing component 15, slightly lift it and then rotate it. When passing the flip support block 13, push it into the storage slot 14. After rotating it to the appropriate position, then... Place the steel plate on the plate and align the left rear corner of the steel plate with the right-angle groove of the fixed angle plate 155. Then, shake the handle 1514 and use the drive shaft 1513 and bevel gear set 1512 to drive the lead screw 1511 to rotate, which in turn drives the screw sleeve 156, U-shaped frame 157, sliding plate 158 and movable fixed angle plate 1510 to move until the right-angle groove of the movable fixed angle plate 1510 clamps the other opposite corner of the steel plate, thus fixing the steel plate. The anti-slip structure at the bottom of the adjustable fixing part 15 is used to maintain the position. Step 2: The vibratory feeder 3 evenly distributes the rivets onto the transition track 4. When the rivets pass through the rivet shaft groove 41 of the transition track 4, the rivet shaft is guided by the rivet shaft groove 41, causing the rivet shaft to rotate downwards and stand upright. When it moves to the right onto the arrangement track 6, the intermittently activated flipping structure 7 pushes the rivet upwards. At this time, the trapezoidal push block 74 first contacts the bottom end of the rivet, and the top inclined surface causes the bottom end of the rivet to deflect backwards until it reaches a horizontal position. Then, the limit bar 75 contacts the U-shaped flipping track 62 and is blocked. The electric push rod 72 continues to push the U-shaped push frame 73 upwards and uses the top inclined surface to push the rivet to the right. The squeezing force of the rivet gradually pushes the right-side rivet to the right. Then, the electric push rod 72 retracts and drives the flipping structure 7 to reset. The electric push rod 72 is activated once for each rivet removed. Step 3: Activate the three-axis moving module 8 to move the clamping and welding structure 9 to the position of the rivet directly behind the next welding location. With the assistance of the industrial camera 99 and a vision recognition system, precisely control the movement position to pick up the rivet. Control the servo motor 94 to operate, and drive the clamping part 93 to rotate backward to a horizontal stop via the transmission belt mechanism 95, so that the sleeve 93 holds the rivet shaft. Then, the electromagnet 932 is energized, generating a repulsive force with the permanent magnet 937 to push out the sliding tube 936, so that it fits the rivet shaft, and the damping block 93... 8. Damping and clamping the rivet shaft, then controlling the three-axis moving module 8 to lift and clamp the welding structure 9 and the rivet, and move it to the welding position. Then controlling the servo motor 94 to lower the clamping part 93 to vertical position, and then controlling the three-axis moving module 8 to lower the clamping welding structure 9 and the rivet until the rivet contacts the steel plate and compresses the conical spring 935, so that the welding gun 98 points to the edge of the rivet head and the gap of the steel plate, and performs four-point welding at the same time, thus completing the welding of one rivet; repeat the above operation until the required rivet welding is completed, stop the machine, and remove the steel plate.
