[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 7 As shown, an all-aluminum battery box conveying device of the present invention includes a conveyor belt 11, a frame 12, a clamping mechanism, a correction mechanism and a positioning mechanism.

[0032] For ease of understanding, in the present embodiment, the length direction of the conveyor belt 11 is defined as the front-to-back direction, and the width direction of the conveyor belt 11 is defined as the left-to-right direction.

[0033] The clamping mechanism, the correcting mechanism and the positioning mechanism are all installed on the frame 12. The conveyor belt 11 is used to convey the battery box 1 from the back to the front so that the battery box 1 passes through the frame 12. The clamping mechanism, the correcting mechanism and the positioning mechanism are each provided with two groups and are symmetrically arranged on the left and right sides of the conveyor belt 11. The clamping mechanism is used to clamp and fix the battery box 1 on the conveyor belt 11 to ensure that the battery box 1 does not move during subsequent welding. The correcting mechanism is used to adjust the clamping position of the battery box 1 to ensure that the battery box 1 is accurately positioned during subsequent welding. The positioning assembly is used to position the side panel formed by the bending of the battery box 1 to ensure that the side panel is bent in place to improve the welding effect of the battery box 1.

[0034] The clamping mechanism includes a clamping plate 21, a driving structure 1 and a driving structure 2. The driving structure 1 is used to drive the clamping plate 21 to move along the width direction of the conveyor belt 11. A telescopic rod 22 is provided on the side of the clamping plate 21 away from the conveyor belt 11. An elastic member 1 is provided in the telescopic rod 22 so that the end face of the clamping plate 21 abuts against the battery box 1. The driving structure 2 is used to drive the telescopic rod 22 to rotate so as to drive the battery box 1 clamped by the clamping plate 21 to flip. The correction mechanism includes two guide blocks 31 and a driving structure 3. The two guide blocks 31 are respectively located at On the front and rear sides of the clamping plate 21, the driving structure three is used to drive the two guide blocks 31 to move, so that the two guide blocks 31 are respectively in contact with the front and rear side plates of the battery box 1, and the battery box 1 is corrected so that the center of the battery box 1 is in line with the clamping center of the clamping plate 21. The positioning mechanism includes a positioning plate 41 and a driving structure four. The positioning plate 41 is L-shaped. The driving structure four is used to drive the positioning plate 41 to move so that the intersection angle of the positioning plate 41 is located at the intersection angle of the bottom plate and the side plate of the battery box 1, so as to position the side plate of the battery box 1.

[0035] Specifically, Figures 1 to 7As shown, in this embodiment, the welding gun is installed on the frame 12, and the battery box 1 is conveyed by the conveyor belt 11. When the battery box 1 passes through the frame 12, the clamping plate 21 is driven by the driving structure 1 to move in the direction close to the conveyor belt 11, so that the battery box 1 is clamped by the clamping plates 21 in the two sets of clamping mechanisms. In addition, when the clamping plates 21 contact the side plates of the battery box 1, the inclined battery box 1 can be straightened; in the process of the clamping plates 21 moving to clamp the battery box 1, the guide blocks 31 are driven by the driving structure 3 to move, so that the two guide blocks 31 are moved. The two guide blocks 31 are respectively in contact with the front and rear sides of the battery box 1. Since the two guide blocks 31 are symmetrically arranged on the front and rear sides of the clamping plate 21, the front and rear positions of the battery box 1 can be adjusted during the relative movement of the two guide blocks 31, so that the center of the battery box 1 and the clamping center of the clamping plate 21 are collinear, thereby ensuring the clamping effect of the battery box 1. In the process of the clamping plate 21 moving to clamp the battery box 1, the positioning plate 41 is driven to move by the driving structure 4, so that the intersection angle of the positioning plate 41 is located at the intersection angle of the bottom plate and the side plate of the battery box 1. Since the positioning plate 41 It is L-shaped, that is, the horizontal arm and the vertical arm are arranged vertically, so that the horizontal arm in the positioning plate 41 fits with the bottom plate of the battery box 1, and the vertical arm in the positioning plate 41 fits with the side plate of the battery box 1. In the process of the vertical arm fitting the side plate of the battery box 1, the side plate is adjusted to a vertical state so that the side plate is bent in place. At this time, the welding seam on the inner side of the battery box 1 is welded by a welding gun. After welding the inner side, the guide block 31 is driven by the driving structure three to move in the reverse direction for reset, and the positioning plate 41 is driven by the driving mechanism four to move in the reverse direction for reset. At this time, the battery box 1 is clamped only by the clamping plate 21 The telescopic rod 22 is then driven to rotate by the driving structure 2, and the battery box 1 clamped by the clamp 21 is driven to flip over so that the bottom of the battery box 1 faces upward. At this time, the weld seam on the outside of the battery box 1 is welded by the welding gun. After welding the outside, the telescopic rod 22 is reversed by the driving structure 2, and the battery box 1 is flipped again so that the bottom of the battery box 1 faces downward. Then, the clamp 21 is driven to move in the opposite direction by the driving structure 1 to reset it, and the clamping of the battery box 1 is released. At this time, the battery box 1 can continue to be conveyed forward to the next process through the conveyor belt 11.

[0036] In some embodiments, a mounting frame 13 is provided on the frame 12, and a guide rail 131 is provided on the mounting frame 13. The guide rail 131 is arranged along the width direction of the conveyor belt 11. The driving structure 1 includes a guide rail plate 23 and a driving member 1 (not shown in the figure). The guide rail plate 23 slides with the mounting frame 13 through the guide rail 131. The driving member 1 is used to drive the guide rail plate 23 to move along the length direction of the guide rail 131. One end of the telescopic rod 22 is fixedly connected to the clamping plate 21, and the other end is rotatably connected to the guide rail plate 23.

[0037] Specifically, Figures 1 to 4As shown, when the battery box 1 is conveyed to the rack 12, the guide plate 23 is driven by the driving member 1 to move along the length direction of the guide rail 131, and the clamping plate 21 is driven by the telescopic rod 22 to move until the end face of the clamping plate 21 contacts the side plate of the battery box 1. At this time, the guide plate 23 is driven by the driving member 1 to continue to move, and the length of the telescopic rod 22 is adapted according to the distance between the guide plate 23 and the battery box 1, so that the clamping mechanism can clamp battery boxes 1 of different sizes, and at the same time avoid excessive extrusion of the battery box 1, prevent the all-aluminum battery box 1 from being deformed by extrusion, and ensure the quality of the battery box 1.

[0038] In some embodiments, the driving structure 2 includes a driving member 24 disposed on the guide plate 23, and the output end of the driving member 24 is connected to the telescopic rod 22, and is used to drive the telescopic rod 22 to rotate around its own axis, thereby driving the battery box 1 clamped by the clamp 21 to flip, so that the welding gun can weld the inside and outside of the battery box 1 successively. In addition, by providing a correction mechanism, the front and rear positions of the battery box 1 can be adjusted so that the center of the battery box 1 is colinear with the clamping center of the clamp 21, so that the battery box 1 can be flipped around the center, so that its position before and after the flipping will not change, that is, there is no need to re-position the flipped battery box 1, thereby improving efficiency.

[0039] In some embodiments, a lifting assembly is provided on the frame 12, and a slide groove 121 is provided on the frame 12 along its height direction. The mounting frame 13 slides with the frame 12 through the slide groove 121. The lifting assembly includes a longitudinally arranged screw rod 14 and a driving member 15 for driving the screw rod 14 to rotate. The screw rod 14 is rotatably arranged in the slide groove 121 and is threadedly engaged with the mounting frame 13.

[0040] Specifically, Figures 1 to 4 As shown, after the welding of the inner side of the battery box 1 is completed, the correction mechanism and the fixing mechanism are reset, and the driving member 3 15 is started to drive the screw 14 to rotate, and drive the mounting frame 13 that is threadedly matched with the screw 14 to move, so that the mounting frame 13 moves upward along the slide groove 121, and drives the guide plate 23 that is slidingly matched with the mounting frame 13 to move upward synchronously, thereby driving the battery box 1 clamped by the clamping plate 21 to move upward, so that the bottom of the battery box 1 is separated from the conveyor belt 11. At this time, the battery box 1 is driven to flip over by the driving structure 2, which can avoid the battery box 1 from colliding with the conveyor belt 11 and ensure the smooth flipping of the battery box 1.

[0041] In some embodiments, a guide rail 2 132 is provided on the mounting frame 13, and the guide rail 2 132 is arranged along the width direction of the conveyor belt 11. The driving structure 3 includes a sliding plate 32 and a driving member. The sliding plate 32 slides with the mounting frame 13 through the guide rail 2 132. A mounting rod 321 is provided at the upper end of the sliding plate 32, and the mounting rod 321 is arranged along the length direction of the conveyor belt 11. Two guide blocks 31 are axially slidably sleeved on both ends of the mounting rod 321, and an elastic member 2 33 for driving the guide block 31 to reset is provided between each guide block 31 and the sliding plate 32. Each guide block 31 is inclined at one end facing the conveyor belt 11, and the inclined surface is inclined from the direction away from the other guide block 31 to the direction close to the conveyor belt 11. The driving member is used to drive the sliding plate 32 to move along the guide rail 2 132.

[0042] Specifically, Figures 1 to 5 As shown, in the process of the clamping plate 21 clamping the battery box 1, the driving member drives the sliding plate 32 to move along the length direction of the guide rail 132, so that the sliding plate 32 moves in the direction close to the conveyor belt 11, and drives the mounting rod 321 provided on the sliding plate 32 to move synchronously, and at the same time drives the guide block 31 that slides with the mounting rod 321 to move, so that the guide block 31 gradually approaches the battery box 1 on the conveyor belt 11, until the guide block 31 contacts the battery box 1, at this time, the four guide blocks 31 in the two groups of correction mechanisms are respectively in contact with the four side ridges of the battery box 1, as the sliding plate 32 continues to approach the conveyor belt 11, Under the guiding action of its own inclined surface, the guide block 31 can make the two guide blocks 31 in the same correction mechanism move away from each other, and make the corresponding elastic member 2 33 stretch to store force, until the two guide blocks 31 are respectively moved to the front and rear sides of the battery box 1, and respectively abut against the front and rear side plates of the battery box 1. In this process, since the two guide blocks 31 are symmetrically arranged on the front and rear sides of the clamping plate 21, the front and rear positions of the battery box 1 can be corrected, so that the center of the battery box 1 is aligned with the clamping center of the clamping plate 21, so that when the battery box 1 is subsequently flipped, its front and rear positions will not change, thereby ensuring the subsequent welding effect of the battery box 1.

[0043] In some embodiments, the driving member includes a rotating ring 34, a rack 1 35, a rack 2 36 and a gear 37. The telescopic rod 22 includes an outer rod 221 and an inner rod 222. The inner rod 222 is rotatably connected to the guide plate 23. One end of the outer rod 221 is connected to the clamping plate 21, and the other end is slidably sleeved on the outer side of the inner rod 222. The rotating ring 34 is rotatably sleeved on the outer side of the outer rod 221. The rack 1 35 is arranged along the width direction of the conveyor belt 11 and is fixedly connected to the rotating ring 34. The rack 2 36 is fixedly arranged on the sliding plate 32 along the width direction of the conveyor belt 11. A connecting rod 42 is installed on the side of the guide plate 23 facing the conveyor belt 11. The gear 37 is rotatably arranged on the connecting rod 42. The gear 37 is arranged between the rack 1 35 and the rack 2 36, and both sides of the gear 37 are simultaneously meshed with the rack 1 35 and the rack 2 36.

[0044] Specifically, when the guide plate 23 and the telescopic rod 22 are driven by the driving member 1 to move in the direction close to the conveyor belt 11, the gear 37 arranged on the connecting rod 42 can be driven to move, and the rotating ring 34 sleeved on the outside of the outer rod 221 can be driven to move synchronously, and the rack 1 35 fixedly connected to the rotating ring 34 can be driven to move. At this time, the meshing connection between the rack 1 35 and the gear 37, and the meshing connection between the rack 2 36 and the gear 37 can drive the rack 2 36 to move, and at the same time drive the sliding plate 32 connected to the rack 2 36 to move, so as to drive the guide block 31 to gradually move in the direction close to the conveyor belt 11. When the clamping plate 21 contacts the side plate of the battery box 1, The guide plate 23 is driven to continue to move by the driving member 1, which will drive the inner rod 222 and the gear 37 to continue to move, while the outer rod 221 is blocked and stops moving, so that the telescopic rod 22 begins to shrink. At this time, the rotating ring 34 sleeved on the outside of the outer rod 221 stops moving, so that the rack 1 35 stops moving, that is, the gear 37 moves relative to the rack 1 35. At this time, the meshing transmission between the rack 1 35 and the gear 37 can drive the gear 37 to rotate, that is, the gear 37 can rotate while moving relative to the rack 1 35. At this time, the meshing transmission between the gear 37 and the rack 2 36 drives the rack 2 36 to continue to move in the direction close to the conveyor belt 11, and the movement of the rack 2 36 When the speed is greater than the moving speed of the gear 37, the rack 23 moves while driving the sliding plate 32 to continue to move, and the moving speed of the sliding plate 32 is greater than the moving speed of the guide plate 23, until the guide block 31 contacts the battery box 1 and gradually moves to the front and rear sides of the battery box 1, and the front and rear positions of the battery box 1 are adjusted. Since the moving speeds of the guide plate 23 and the guide block 31 are different, the clamping force of the clamping plate 21 gradually increases, and the guide block 31 can correct the battery box 1 faster, thereby improving the correction efficiency; when the guide plate 23 is driven by the driving member 1 to move in the direction away from the conveyor belt 11, the outer rod 221 remains stationary, so that the clamping plate 21 continues to clamp the battery box 1 At the same time, the inner rod 222 moves relative to the outer rod 221 in the direction away from the conveyor belt 11, so that the telescopic rod 22 gradually extends. As the guide plate 23 moves, the gear 37 is driven to move relative to the rack 1 35, and through the meshing between the two, the gear 37 is driven to rotate. At the same time, through the meshing transmission between the gear 37 and the rack 2 36, the rack 2 36 and the sliding plate 32 are driven to move in the direction away from the conveyor belt 11, so that the guide block 31 is gradually reset; when the guide block 31 is out of contact with the battery box 1, the clamping plate 21 still clamps the battery box 1 under the action of the elastic member 1. At this time, the telescopic rod 22 is driven to rotate by the driving structure 2, which can drive the battery box 1 to flip.

[0045] In some embodiments, the positioning plate 41 includes a positioning plate 1 411 for positioning the left and right side panels of the battery box 1, and two positioning plates 412 for positioning the front and rear side panels of the battery box 1. The positioning plate 1 411 is installed at the end of the connecting rod 42 away from the guide plate 23. In the initial state, the distance between the clamping plate 21 and the battery box 1 is smaller than the distance between the positioning plate 1 411 and the battery box 1.

[0046] Specifically, Figures 1 to 6 As shown, when the guide plate 23 is driven to move by the driving member 1, the connecting rod 42 can be driven to move synchronously, and the positioning plate 411 can be driven to move at the same time, so that the positioning plate 411 gradually approaches the battery box 1 until the intersection of the positioning plate 411 moves to the intersection of the bottom plate and the side plate of the battery box 1. At this time, the horizontal arm of the positioning plate 411 is in contact with the bottom plate of the battery box 1, and the vertical arm of the positioning plate 411 is in contact with the left plate or the right plate of the battery box 1, so that the left and right side plates of the battery box 1 are adjusted to a vertical state to ensure that the side plates are bent in place. Because in the initial state, the distance between the clamping plate 21 and the battery box 1 is smaller than the distance between the positioning plate 411 and the battery box 1, when the driving member 1 drives the guide plate 23 to move, the clamping plate 21 will first contact with the battery box 1 to align and clamp the battery box 1, and then the positioning plate 411 will contact with the battery box 1 to position the side plates to ensure accurate positioning of the side plates.

[0047] In some embodiments, the upper end of the conveyor belt 11 is provided with a receiving groove for receiving the positioning plate 411, specifically, as Figures 1 to 4 As shown, the conveyor belt 11 is composed of a conveyor frame 111 and a plurality of conveyor rollers 112 rotatably arranged on the conveyor frame 111, each conveyor roller 112 is arranged along the width direction of the conveyor frame 111, and a receiving groove is arranged between two adjacent conveyor rollers 112, so that when the bottom of the battery box 1 contacts the conveyor belt 11, the positioning plate 411 can move in the receiving groove until the cross arm in the positioning plate 411 fits with the bottom of the battery box 1, thereby positioning the side panel of the battery box 1.

[0048] In some embodiments, the two positioning plates 412 are symmetrically arranged on the front and rear sides of the sliding plate 32, and the driving structure four is set to two groups, which are respectively used to drive the two positioning plates 412 to move. Each group of driving structure four includes a moving part 43 and a guide part 44. The moving part 43 is slidably arranged at the lower end of the sliding plate 32 along the length direction of the conveyor belt 11, and an elastic part three 45 is provided between the moving part 43 and the sliding plate 32 for driving the moving part 43 to reset. The positioning plate 412 is arranged on the moving part 43, and the guide part 44 is inclined on the frame 12. When the mounting frame 13 moves upward along the slide groove 121, the moving part 43 can contact the guide part 44, so that the moving part 43 moves in the direction close to the other positioning plate 412.

[0049] Specifically, Figures 1 to 7 As shown, when the battery box 1 on the conveyor belt 11 passes through the frame 12, the clamping plate 21 is moved by the driving structure 1 to clamp the battery box 1, and the guide block 31 is moved by the driving structure 3, so that the guide block 31 abuts against the front and rear side plates of the battery box 1, and then the screw 14 is rotated by the driving member 3 15, so that the mounting frame 13 moves upward along the slide groove 121, and drives the battery box 1 clamped by the clamping plate 21 to move upward synchronously. With the movement of the mounting frame 13, the guide plate 23 and the sliding plate 32 that slide with the mounting frame 13 are driven to move upward, and at the same time, the moving member 43 arranged at the lower end of the sliding plate 32 is driven to move upward, and the moving member 43 arranged at the lower end of the sliding plate 32 is driven to move upward, and the moving member 43 arranged at the moving member 1 The second positioning plate 412 on the moving member 43 moves, and during this process, the moving member 43 will contact the guide member 44 provided on the frame 12, so that the moving member 43 and the second positioning plate 412 move in the direction close to the battery box 1, and the elastic member 3 45 is stretched to store force. At this time, the two second positioning plates 412 can approach each other, and the front and rear side plates of the battery box 1 are positioned, so that the four side plates of the front, back, left and right of the battery box 1 are all bent in place, and then the weld on the inside of the battery box 1 can be welded by a welding gun; after welding the inside, the screw 14 is reversed by the driving member 3 15, and the mounting frame 13 is driven to move downward, and the battery box 1 clamped by the clamping plate 21 is driven to move downward synchronously. As the mounting bracket 13 moves, the guide plate 23 and the sliding plate 32 are driven to move downward, and the moving member 43 and the second positioning plate 412 are driven to move downward. During this process, the elastic member 3 45 is released to drive the moving member 43 and the second positioning plate 412 to move away from the battery box 1. At this time, the two second positioning plates 412 move away from each other to reset and break away from the contact with the battery box 1. At the same time, the guide plate 23 is driven to move away from the battery box 1 through the driving member 1, and the positioning plate 1 411 is driven to move and reset. At the same time, the guide block 31 is reset under the action of the driving structure 3. When the guide block 31, the positioning plate 1 411 and the positioning plate 2 412 are all When the resetting is completed, the battery box 1 is clamped only by the clamping plate 21, and at this time there is still a certain distance between the lower end of the battery box 1 and the conveyor belt 11. At this time, the telescopic rod 22 is driven to rotate by the driving structure 2, and the battery box 1 clamped by the clamping plate 21 is driven to flip over, and then the weld seam on the outside of the battery box 1 is welded by the welding gun. After completing the welding of the outside, the battery box 1 is flipped again, and then the mounting frame 13 is driven by the driving member 3 15 to continue to move downward until the bottom of the battery box 1 contacts the conveyor belt 11. At this time, the clamping plate 21 is driven away from the battery box 1 by the driving structure 1, and the clamping of the battery box 1 is released. The battery box 1 continues to be conveyed forward to the next process through the conveyor belt 11.

[0050] In some embodiments, the second positioning plate 412 is longitudinally slidably disposed at the lower end of the movable member 43, and an elastic member 46 is provided between the second positioning plate 412 and the movable member 43 for driving the second positioning plate 412 to reset, and a stopper 16 capable of blocking the second positioning plate 412 is provided on the frame 12.

[0051] Specifically, Figures 1 to 7 As shown, in the initial state, the second positioning plate 412 is in contact with the upper end of the stopper 16, and the elastic member 46 is in a compressed force storage state. At this time, the lower end of the second positioning plate 412 is flush with the surface of the conveyor belt 11, avoiding the second positioning plate 412 from colliding with the conveyor belt 11 during the movement; when the screw 14 is driven to rotate by the driving member 3 15, the mounting frame 13 is driven to move upward, and the battery box 1 clamped by the clamping plate 21 is driven to move upward, and the moving member 43 is driven to move upward at the same time. During this process, the elastic member 46 is released, so that the second positioning plate 412 remains stationary until the elastic member 46 is completely released. At this time, the lower end of the second positioning plate 412 is still flush with the surface of the conveyor belt 11, and the battery box 1 moves a certain distance upward relative to the conveyor belt 11. , so that the height of the second positioning plate 412 is lower than the lower end of the battery box 1, and then the mounting frame 13 continues to move upward, driving the battery box 1 to continue to move upward, and at the same time driving the moving member 43 and the second positioning plate 412 to move upward. At this time, the battery box 1 and the second positioning plate 412 move upward synchronously. In this process, the two second positioning plates 412 are made close to each other through the driving structure four, and the second positioning plate 412 can be moved to the intersection of the bottom plate of the battery box 1 and the front and rear side plates to position the front and rear side plates of the battery box 1, that is, when the battery box 1 is located on the conveyor belt 11, the second positioning plate 412 can give way to avoid conflict with the conveyor belt 11. When the battery box 1 moves upward, the second positioning plate 412 is reset, so that it can move to the intersection of the battery box 1 to position the front and rear side plates of the battery box 1.
