Description

Technical Field

[0001] This invention relates to laser cutting equipment, and in particular to a high-precision automatic loading and unloading laser cutting device for sheet metal processing of energy storage containers, belonging to the technical field of sheet metal processing equipment. Background Technology

[0002] The main components of energy storage containers, such as the side panels, top panels, bottom panels, frame reinforcing ribs, and internal battery cluster mounting brackets, are all large-sized sheet metal parts. To meet the needs of large-scale and batch processing of sheet metal parts for energy storage containers, high-power laser cutting equipment has become the core processing equipment in this field. Most existing laser cutting equipment is equipped with automatic loading and unloading devices, which can realize automatic loading and cutting of the sheet metal to be processed, greatly improving the efficiency of sheet metal processing.

[0003] However, during the transfer of finished materials, the forks in the loading and unloading grippers need to pass horizontally through the gaps between the saw teeth of the cutting table to reach the bottom of the sheet material, and then lift and transfer the shaped material upwards. Since there are gaps between adjacent forks, and a large amount of waste material from the cutting and separation will remain on the surface of the sheet material after laser cutting, these waste materials are very likely to fall from the gaps between the forks during the lifting and lateral transfer of the sheet material by the forks, and directly scatter on the top surface of the saw teeth and in the gaps between the teeth of the cutting table. This will directly cause unevenness when the sheet material to be processed is placed, affecting the cutting accuracy. If manual cleaning is used, it will increase the labor cost.

[0004] To address these issues, a high-precision automatic loading and unloading laser cutting device for sheet metal processing of energy storage containers was designed. Summary of the Invention

[0010] Preferably, a waste pusher plate is provided between two adjacent sets of top plates. The waste pusher plate is connected to the vibration mechanism and is used to move horizontally back and forth along the width direction of the cutting table as the vibration mechanism runs.

[0011] Preferably, the waste pusher plate has an isosceles triangular cross-sectional shape, with the inclined surface of the waste pusher plate facing the cutting table. A second vertical groove is provided on the side wall of the waste pusher plate, and an arc-shaped drive shaft passes through the inside of the second vertical groove.

[0019] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0020] like Figures 1-10 As shown, this embodiment provides a high-precision automatic loading and unloading laser cutting device for sheet metal processing of energy storage containers, including a laser cutting machine body 1, a support slide 101 located at the front end of the laser cutting machine body 1, a cutting table 102 slidably disposed on the top of the support slide 101, saw blades arranged parallel to each other on the top of the cutting table 102, a gantry 2 located on the top of the cutting table 102, a horizontal slide 201 slidably disposed along the length of the gantry 2, a vertical slide 202 slidably disposed on the horizontal slide 201, a loading and unloading gripper 203 disposed at the bottom end of the vertical slide 202, and finished product carts 204 and unprocessed material carts 205 disposed at both ends of the bottom of the gantry 2; A top plate 3 is provided between adjacent saw blades at the bottom of the cutting table 102, and there is a height difference between the tops of adjacent top plates 3; A shaking mechanism 4 is provided between the gantry 2 and the cutting table 102. The shaking mechanism 4 is linked with the horizontal material transfer action of the horizontal slide table 201. It is used to drive each top plate 3 to move up and down reciprocally during the process of the horizontal slide table 201 driving the molding material to transfer and reset. A vibration mechanism 6 is provided at the end of the support slide 101. The vibration mechanism 6 is connected to the shaking mechanism 4 and is used to apply impact vibration to the cutting table 102 during the reciprocating movement of the top plate 3.

[0021] After the laser cutting machine body 1 completes the cutting of the sheet metal of the energy storage container, the cutting table 102 slides along the support slide 101 to the loading and unloading station, aligning with the loading and unloading stroke of the gantry 2, waiting for the unloading operation. The vertical slide 202 moves vertically down along the horizontal slide 201, driving the loading and unloading gripper 203 to move to the cutting table 102. The gripper fork of the loading and unloading gripper 203 horizontally inserts through the gap between the adjacent saw blades of the cutting table 102, lifting the cut sheet metal. Then the vertical slide 202 moves up, driving the cut material to be lifted off the top surface of the saw blades of the cutting table 102.

[0022] The horizontal slide table 201 moves horizontally along the length of the gantry 2 toward the finished material cart 204, driving the loading and unloading grippers 203 to transfer the formed material for unloading. During this process, the movement of the horizontal slide table 201 simultaneously triggers the start of the shaking mechanism 4. The shaking mechanism 4 drives multiple sets of top plates 3 to move up and down along the gap between the saw teeth of the cutting table 102. By utilizing the initial height difference between adjacent top plates 3, a staggered pushing force is formed, which pushes and shakes the corner scraps and slag fragments that fall onto the top surface of the saw teeth and the gap between the teeth of the cutting table 102 during the unloading process downward from the gap between the teeth, so as to avoid the waste residue causing unevenness of the subsequent loading plates.

[0023] While the shaking mechanism 4 is running, it simultaneously drives the vibration mechanism 6 to run. The vibration mechanism 6 applies impact vibration to the cutting table 102, which, together with the pushing action of the top plate 3, eliminates the adhesion and jamming of molten slag between the waste and the saw blade, further improving the thoroughness of waste shaking. During the operation of the shaking mechanism 4, it simultaneously drives the waste push plate 5 between the adjacent top plates 3 to move horizontally back and forth along the width direction of the cutting table 102, pushing the waste that has fallen to the bottom of the cutting table 102 to the waste collection areas on both sides of the equipment, realizing the centralized cleaning of waste and avoiding the accumulation of waste at the bottom of the equipment.

[0024] After the horizontal slide table 201 moves above the finished product cart 204, the vertical slide table 202 descends and places the molded material on the finished product cart 204 to complete the unloading. Then, the horizontal slide table 201 moves back to its original position along the gantry 2 toward the material cart 205 to be processed. During this process, the shaking mechanism 4 continues to run, driving the top plate 3, the waste push plate 5, and the vibration mechanism 6 to continuously complete the material cleaning operation until the horizontal slide table 201 is reset. Then, the horizontal slide table 201 moves above the material cart 205 to complete the gripping of the material to be processed, and then moves above the cutting table 102 to complete the loading, entering the next round of cutting cycle.

[0025] In this embodiment, the thickness of the top plate 3 is less than the gap width between adjacent saw blades on the cutting table 102, ensuring that the top plate 3 will not rigidly interfere with the saw blades when moving up and down within the gap of the saw blades; the initial state of the top surface of the top plate 3 is flush with or lower than the bottom surface of the cutting table 102. During the cutting operation and the movement of the fork, the top plate 3 is completely contained below the bottom surface of the cutting table 102, and will not interfere with the sliding of the cutting table 102 or the movement of the fork; multiple sets of top plates 3 form a staggered high and low structure along the width of the cutting table 102. When the shaking mechanism 4 drives each top plate 3 to move up and down synchronously, the adjacent top plates 3 will form a staggered pushing action, which will form a continuous and dead-angle-free pushing force on the waste material in the gap of the cutting table 102, and prevent the waste material from forming a stuck fulcrum in the tooth groove and being unable to fall.

[0026] In this embodiment, the shaking mechanism 4 includes an arc-shaped drive shaft 411, a horizontal guide groove 412, a limiting rod 413, a first vertical groove 414, and a transmission assembly; An arc-shaped drive shaft 411 is rotatably mounted between the two ends of the support slide 101. A horizontal guide groove 412 is provided between both sides of the top plate 3, and the arc-shaped drive shaft 411 passes through the horizontal guide groove 412. Limiting rods 413 are symmetrically fixed between the two ends of the support slide 101. The top plate 3 has a first vertical groove 414 at both ends. The two sets of limiting rods 413 pass through the first vertical groove 414 at the ends of the top plate 3 to vertically limit the top plate 3. One end of the bow-shaped drive shaft 411 extends to the outer end of the support slide 101, and the end of the bow-shaped drive shaft 411 is provided with a transmission assembly for driving the bow-shaped drive shaft 411 to rotate when the horizontal slide 201 moves laterally to unload materials.

[0027] When the transmission assembly drives the bow-shaped drive shaft 411 to rotate circumferentially around its own axis, the rod of the bow-shaped drive shaft 411 rotates circumferentially within the horizontal guide groove 412, simultaneously applying a vertical reciprocating force to the inner wall of the horizontal guide groove 412. Meanwhile, the top plate 3, through the first vertical grooves 414 at both ends and the limiting rod 413, is restricted to reciprocating movement only in the vertical direction and cannot generate horizontal displacement. Therefore, the rotation of the bow-shaped drive shaft 411 is converted into the top plate 3 reciprocating vertically up and down along the limiting rod 413, achieving a pushing and shaking action on the waste material within the gap of the cutting table 102. Simultaneously, multiple sets of top plates 3 share the same bow-shaped drive shaft 411, ensuring the synchronization of the movements of all top plates 3. Furthermore, by adjusting the height of the bow-shaped protrusions of the bow-shaped drive shaft 411 corresponding to different positions of the top plates 3, the difference in the reciprocating stroke of adjacent top plates 3 can be precisely controlled. Combined with the initial height difference between adjacent top plates 3, this further enhances the material shaking effect of the staggered pushing action.

[0028] In this embodiment, the transmission assembly includes a fixed block 401, a slide bar 402, a rack 403, a first spring 404, a first lever 405, a column 406, a spur gear 407, a transmission rod 408, a first bevel gear 409, and a second bevel gear 410. Fixed blocks 401 are fixedly installed at both ends of the same outer side wall of the support slide 101. A slide rod 402 is fixedly installed between the two sets of fixed blocks 401. A rack 403 is slidably installed on the slide rod 402 along the length direction. A first lever 405 is vertically fixed at the top end of the rack 403 near the finished material cart 204. The top of the first lever 405 is higher than the bottom horizontal plane of the horizontal slide table 201. When the horizontal slide table 201 moves, the rack 403 is dragged to slide by the first lever 405. A first spring 404 is provided between the end of the rack 403 near the finished product cart 204 and the fixed block 401, and the first spring 404 is sleeved on the outside of the slide bar 402; A column 406 is vertically fixed at the middle of the front end of the support slide 101. A transmission rod 408 is vertically rotatably mounted inside the column 406. A spur gear 407 that meshes with a rack 403 is fixed at the top of the transmission rod 408. A first bevel gear 409 is fixed at the bottom of the transmission rod 408. A second bevel gear 410 that meshes with the first bevel gear 409 is fixed at the end of the bow-shaped drive shaft 411.

[0029] When the horizontal slide table 201 moves laterally along the gantry 2 towards the finished product cart 204 to unload material, the side wall of the horizontal slide table 201 contacts the first lever 405 and pushes the first lever 405 to move synchronously towards the finished product cart 204. The first lever 405 drives the rack 403 to slide horizontally along the slide rod 402, while compressing the first spring 404 to store energy. During the sliding process of the rack 403, the gear meshing drives the spur gear 407 to rotate around the vertical axis. The spur gear 407 drives the transmission rod 408 to rotate synchronously. The first bevel gear 409 at the bottom of the transmission rod 408 rotates synchronously. Through the bevel gear meshing, the second bevel gear 410 rotates around the horizontal axis. Finally, the second bevel gear 410 drives the bow-shaped drive shaft 411 to rotate synchronously, realizing the driving of the material shaking action.

[0030] When the horizontal slide table 201 moves back towards the material trolley 205 after completing the unloading, the horizontal slide table 201 disengages from the first lever 405, and the first spring 404 releases its elastic potential energy, pushing the rack 403 to slide back along the slide bar 402. During the reverse sliding process of the rack 403, the bow-shaped drive shaft 411 is driven to rotate continuously again through the spur gear 407, transmission rod 408, first bevel gear 409, and second bevel gear 410, so that the top plate 3 continues to complete the shaking operation during the reset process of the horizontal slide table 201, realizing the material clearing action of the entire stroke of unloading and reset. No additional drive motor is required. The full linkage drive can be achieved by the movement of the horizontal slide table 201 alone, which greatly reduces the equipment modification cost and energy consumption, and is suitable for the unattended continuous production of energy storage container production lines.

[0031] In this embodiment, a waste pusher plate 5 is provided between two adjacent sets of top plates 3. The waste pusher plate 5 is connected to the vibration mechanism 4 and is used to move horizontally back and forth along the width direction of the cutting table 102 as the vibration mechanism 4 runs.

[0032] While the bow-shaped drive shaft 411 rotates to drive the top plate 3 to shake the material up and down, the bow-shaped drive shaft 411 simultaneously drives the waste push plate 5 to move horizontally back and forth along the width of the cutting table 102. The movement stroke of the waste push plate 5 covers the entire width of the cutting table 102, which can continuously push the waste and slag that fall from the tooth groove gap to the bottom of the cutting table 102 to both sides of the equipment, avoiding the long-term accumulation of waste at the bottom of the cutting table 102, preventing the waste from jamming the movement of the top plate 3 and affecting the normal sliding of the cutting table 102. At the same time, there is no need for manual periodic shutdown to clean the waste at the bottom of the equipment, which greatly reduces the manual operation and maintenance costs and improves the continuity of production.

[0033] In this embodiment, the cross-sectional shape of the waste pusher plate 5 is an isosceles triangle structure, and the inclined surface of the waste pusher plate 5 faces the cutting table 102. The side wall of the waste pusher plate 5 is provided with a second vertical groove 501, and the bow-shaped drive shaft 411 passes through the inside of the second vertical groove 501. The bottom of the waste pusher plate 5 is rotatably mounted with a moving wheel 502.

[0034] When the bow-shaped drive shaft 411 rotates, its rod body makes a circumferential rotational motion in the second vertical groove 501, applying a horizontal reciprocating force to the inner wall of the second vertical groove 501, driving the waste push plate 5 to move horizontally reciprocally; the moving wheel 502 at the bottom of the waste push plate 5 converts sliding friction into rolling friction, greatly reducing the moving resistance and ensuring the smoothness of the pushing action; the isosceles triangular cross-section structure allows its inclined surface to fit the narrow installation space at the bottom of the cutting table 102, and at the same time, during the pushing process, the guiding effect of the inclined surface is used to guide the falling waste downward, avoiding the accumulation of waste on the top of the push plate and ensuring the thoroughness of the pushing.

[0035] In this embodiment, the vibration mechanism 6 includes a mounting groove 601, a vertical rod 602, a mounting plate 603, an impact block 604, a connecting plate 605, a second spring 606, and a lifting assembly; The mounting groove 601 is opened inside the front end of the support slide 101. The vertical rod 602 is vertically slidably set at both ends of the mounting groove 601, and the top of the vertical rod 602 extends to the top of the support slide 101. The mounting plate 603 is fixed between the top ends of the two sets of vertical rods 602, and the mounting plate 603 is located above the front end of the cutting table 102. The bottom of the mounting plate 603 is evenly and vertically fixed with impact blocks 604 along the length direction. The impact end of the impact block 604 faces the top surface of the cutting table 102. In the non-working state, there is a clearance between it and the top surface of the cutting table 102. When impacting, it contacts the top surface of the cutting table 102 to form an impact. A connecting plate 605 is fixedly installed between the bottom ends of the vertical rod 602. A second spring 606 is evenly arranged between the top of the connecting plate 605 and the inner top of the mounting groove 601. A lifting assembly is provided between the connecting plate 605 and the bow-shaped drive shaft 411, which is used to lift the impact block 604 upward when the bow-shaped drive shaft 411 rotates and reset it under the elastic force of the second spring 606 to make a downward impact action.

[0036] During the process of the bow-shaped drive shaft 411 rotating to drive the top plate 3 to shake the material, the connecting plate 605 is simultaneously driven by the lifting component to overcome the elastic force of the second spring 606 and move vertically upward along the mounting groove 601. The connecting plate 605 drives the mounting plate 603 and the impact block 604 to rise synchronously through the vertical rod 602. When the transmission engagement between the lifting component and the connecting plate 605 is disengaged, the second spring 606 instantly releases its elastic potential energy, pushing the connecting plate 605, the vertical rod 602, the mounting plate 603 and the impact block 604 to quickly move vertically downward, so that the impact block 604 impacts the top surface of the cutting table 102, causing the cutting table 102 to produce synchronous micro-vibration. Combined with the up and down pushing action of the top plate 3, the thoroughness of waste removal can be greatly improved. At the same time, it avoids the problem of uneven plate placement caused by small slag and fragments, ensuring the accuracy and stability of laser cutting.

[0037] In this embodiment, the lifting assembly includes a strip groove 607, a slider 608, a third spring 609, a second lever 610, and a third lever 611; The strip grooves 607 are symmetrically opened on the outside of the connecting plate 605. The sliders 608 are slidably installed inside the strip grooves 607, and the sliders 608 are located inside the strip grooves 607 near the end of the bow-shaped drive shaft 411. A third spring 609 is provided between the side of the slider 608 away from the second bevel gear 410 and the end face of the strip groove 607. The outer side of the slider 608 is vertically fixed with a second lever 610. The side of the bow-shaped drive shaft 411 is vertically fixed with a third lever 611 in the radial direction, and the stroke of the third lever 611 is adapted to the second lever 610.

[0038] When the bow-shaped drive shaft 411 rotates, it drives the third lever 611 at its end to rotate circumferentially in sync. When the third lever 611 rotates to contact the second lever 610, the second lever 610 drives the slider 608 and the connecting plate 605 to rise synchronously, while compressing the second spring 606 to store energy. When the third lever 611 rotates to the critical point of contact with the second lever 610, the vertically upward component of the force on the second lever 610 disappears, and the horizontal component of the force pushes the slider 608 to slide along the strip groove 607 and compresses the third spring 609. This causes the third lever 611 to momentarily disengage from the second lever 610. At this moment, the second spring 606 quickly releases its elastic potential energy, driving the impact block 604 downward to complete the impact action. After the impact is completed, the third spring 609 releases its elastic potential energy, pushing the slider 608 to reset along the strip groove 607, waiting for the next contact with the third lever 611. This cycle is repeated so that the impact block 604 completes one impact action for every revolution of the bow-shaped drive shaft 411, and the impact frequency is perfectly matched with the reciprocating movement frequency of the top plate 3, forming a composite material cleaning effect.

[0039] In this embodiment, both the second lever 610 and the third lever 611 are cylindrical in shape, which avoids jamming and impact wear caused by sharp corner contact; and the surfaces of the second lever 610 and the third lever 611 are coated with a wear-resistant coating, which reduces wear caused by repeated contact and impact between the levers and extends the service life of the parts.

[0040] In this embodiment, the highest point of the vertical travel of the top plate 3 is not lower than the top surface of the saw blade, ensuring that when the top plate 3 moves upward, it can completely lift up the waste material stuck on the top surface of the saw blade and the top of the tooth groove, causing it to lose its support point and fall down, thus avoiding the waste material getting stuck on the top surface of the saw blade and being unable to be cleaned; the lowest point of the vertical travel of the top plate 3 is lower than the bottom surface of the cutting table 102, so that the top plate 3 can be completely stored below the bottom surface of the cutting table 102 when it is not in working state, cutting operation state, or fork-passing state, without interfering with the reciprocating sliding of the cutting table 102 along the support slide 101, and without causing movement conflict with the fork-passing action of the loading and unloading gripper 203.

[0041] Material preparation stage: The horizontal slide table 201 moves along the gantry 2 to above the material trolley 205 to be processed. The vertical slide table 202 drives the loading and unloading gripper 203 to descend and grab the sheet metal of the energy storage container to be processed. Then the vertical slide table 202 moves upward and lifts the sheet metal to a safe height. The horizontal slide table 201 moves along the gantry 2 to above the cutting table 102 and waits for material to be loaded. During this process, the top plate 3 is in an initial low position. The top surface is flush with or lower than the bottom surface of the cutting table 102, completely avoiding the sliding path of the cutting table 102. The cutting table 102 slides along the support slide 101 from the cutting station of the laser cutting machine body 1 to the loading and unloading station, aligning with the loading and unloading stroke of the gantry 2.

[0042] Material loading and cutting stage: The vertical slide table 202 descends, and the loading and unloading grippers 203 place the sheet metal to be processed stably on the top surface of the saw blade of the cutting table 102, completing the material loading; then the cutting table 102 slides along the support slide 101 to the cutting position of the laser cutting machine body 1, the laser cutting machine body 1 starts, and completes the cutting of sheet metal parts such as the side panel, top panel, bottom panel, frame reinforcing ribs, and battery cluster mounting bracket of the energy storage container; during this process, the shaking mechanism 4 and the vibration mechanism 6 are in a non-working state, and the top panel 3 is always kept in a low-position storage state, which will not affect the cutting operation.

[0043] Material unloading and linkage cleaning start-up stage: After the cutting operation is completed, the cutting table 102 slides to the loading and unloading station again, the vertical slide 202 descends, and drives the fork of the loading and unloading gripper 203 to horizontally enter through the gap between the adjacent saw blades of the cutting table 102, lifting the cut sheet metal material. The vertical slide 202 ascends and drives the material to rise and detach from the top surface of the saw blades. Then the horizontal slide 201 moves horizontally along the gantry 2 toward the finished material cart 204 to start the unloading operation. At the same time, the side wall of the horizontal slide 201 contacts the first lever 405, pushing the first lever 405 to move synchronously, triggering the start of the shaking mechanism 4.

[0044] Pushing and shaking the material: The first lever 405 drives the rack 403 to slide along the slide bar 402. Through the meshing transmission of the spur gear 407, transmission rod 408, first bevel gear 409, and second bevel gear 410, the bow-shaped drive shaft 411 is driven to rotate. The bow-shaped drive shaft 411 drives multiple sets of top plates 3 to move up and down along the limiting rod 413 through the horizontal guide groove 412. By utilizing the initial height difference of adjacent top plates 3 and the misaligned pushing action, the corner scraps and slag fragments that fall during the unloading process are shaken off from the tooth groove gap of the cutting table 102.

[0045] Synchronous feeding: While the bow-shaped drive shaft 411 rotates, it drives the waste push plate 5 to move horizontally back and forth along the width of the cutting table 102 through the second vertical groove 501, pushing the waste that falls to the bottom of the cutting table 102 into the waste collection troughs on both sides of the equipment, thus completing the centralized cleaning of waste.

[0046] Vibration cleaning: During the rotation of the bow-shaped drive shaft 411, the third lever 611 at its end and the second lever 610 work together in a cycle to drive the impact block 604 to reciprocate the impact on the cutting table 102, causing the cutting table 102 to vibrate synchronously. Combined with the pushing action of the top plate 3, the adhesion and jamming of waste material and saw blade are eliminated, further improving the thoroughness of cleaning.

[0047] Material unloading and reset cleaning stage: After the horizontal slide table 201 moves above the finished product cart 204, the vertical slide table 202 moves down to place the molded material on the finished product cart 204, completing the unloading operation; then the horizontal slide table 201 moves back to the direction of the gantry 2 toward the material cart 205 to be processed, the horizontal slide table 201 disengages from the first lever 405, the first spring 404 pushes the rack 403 to slide back to reset, during this process the bow-shaped drive shaft 411 continues to rotate through the transmission structure, so that the top plate 3, the waste push plate 5, and the vibration mechanism 6 continue to complete the cleaning operation, ensuring that there is no waste residue on the table surface of the cutting table 102.

[0048] Cyclic operation phase: After the horizontal slide table 201 is reset above the material trolley 205 to be processed, it grabs the next sheet to be processed, moves it again above the cutting table 102 to complete the loading, and the cutting table 102 slides to the cutting station to enter the next cycle, realizing fully automated, continuous and high-precision processing of sheet metal parts for energy storage containers.

[0049] The above description is merely a further 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 disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
