Description

Technical Field

[0001] This application relates to the field of storage equipment for new energy battery frame production, and in particular to an automatic loading and unloading vehicle for new energy battery frames. Background Technology

[0002] The battery frame is an essential support component of the new energy battery system, mainly bearing the weight of the battery system and providing protection. During the manufacturing process, strict quality control is required to ensure the coordinated operation of each part, so as to achieve efficient, safe and stable operation of the new energy battery.

[0003] Existing new energy battery frames are usually produced using automated processes. The production of battery frames involves the loading, unloading, and storage of battery frames. The traditional method is to load and unload one piece at a time, using a buffer platform or buffer slide. This requires long-term human intervention to promptly remove the products. Battery frames typically weigh over 110 kg and have a size of 3M×2M. This results in high labor intensity due to frequent manual loading and unloading, low production efficiency, reduced capacity, and increased costs. Summary of the Invention

[0004] This application proposes an automatic loading and unloading vehicle for new energy battery frames, which has the advantages of high efficiency and low cost in loading and unloading during battery frame production, thereby solving the technical problems existing in the current battery frame production due to single-piece loading and unloading.

[0005] To achieve the above objectives, this application adopts the following technical solution: an automatic loading and unloading cart for new energy battery frames, comprising a cart body for storing battery frames and a positioning frame for positioning the cart body. The positioning frame is set in the loading area and the unloading area, and the positioning frame is U-shaped. Support columns are fixedly installed at both ends of the top of the cart body, and four support columns are respectively close to the four corners of the top of the cart body. Several positioning shafts are fixedly installed on the support columns. The number of positioning shafts is not less than two, and the several positioning shafts are longitudinally and equidistantly distributed on the support columns. Each positioning shaft is movably fitted with a material supporting mechanism.

[0006] The material support mechanism includes a guide block movably mounted on a positioning support shaft. One end of the guide block is connected to a support block for supporting the battery frame, and the side of the guide block facing the support block is designed with an incline. The end of the guide block away from the support block is connected to a gravity block.

[0007] When in use, push one end of the material cart body into the positioning frame for unloading and storing battery frames or retrieving materials. Each layer of the material support mechanism is subjected to the gravity of the gravity block and rotates around the positioning support shaft, without affecting the unloading or retrieval of the next layer of battery frames.

[0008] Furthermore, the guide block, support block, and gravity block are designed as a single integrated unit.

[0009] Furthermore, the inner side of the positioning frame is provided with a number of guide wheels, the number of which is not less than two, and both ends of the material cart body are provided with guide ramps.

[0010] Furthermore, guide blocks are fixedly installed on both sides of one end of the material cart body. A guide rod is fixedly installed in the middle of the side of the guide block away from the material cart body. The end of the guide rod away from the guide block is spherical. A limiting block corresponding to the guide rod is fixedly installed on the side of the positioning frame facing the material cart body. A groove is opened on the side of the limiting block away from the positioning frame. The groove width decreases uniformly from the outside to the inside, and the innermost side of the groove is adapted to the guide rod.

[0011] Furthermore, anti-misalignment plates are fixedly installed on the top of both ends of the material cart body. The anti-misalignment plates are close to the middle of the material cart body, and a limit groove is opened in the middle of the anti-misalignment plates. A positioning mounting plate located on one side of the anti-misalignment plate is fixedly installed on the positioning frame. A swing cylinder facing the anti-misalignment plate is fixedly installed on the positioning mounting plate. The output shaft of the swing cylinder extends to one side of the limit groove and is fixedly connected to a passive plate. The height of the passive plate is less than the height of the limit groove, and the height of the passive plate is greater than the width of the limit groove. A contact sensor located on one side of one of the limit blocks is fixedly installed on the positioning frame.

[0012] Furthermore, a number of limiting shafts are fixedly installed on the support column, with no less than two limiting shafts. The limiting shafts are arranged longitudinally at equal intervals on the support column, and the limiting shafts are located on one side of the positioning support shaft. A limiting shaft located diagonally below the bottom limiting shaft on the support column is fixedly installed on the support column, and the limiting shaft is located on the other side of the positioning support shaft.

[0013] Furthermore, a column is fixedly installed on the positioning frame, and the same number of material sensors as the material support mechanism on the support column are fixedly installed on the column, with each layer of material sensors corresponding one-to-one with each layer of material support mechanism on the support column.

[0014] Furthermore, two support columns at one end of the material cart body are respectively provided with transverse guide grooves adapted to the positioning support shaft. A baffle located between the support column and the material support mechanism is movably fitted on the positioning support shaft away from the material support mechanism. The two sides of the baffle are respectively attached to one side of the material support mechanism and one side of the support column. A linkage block is fixedly connected to the end of the positioning support shaft away from the material support mechanism. One side of the linkage block is attached to the other side of the support column. A positioning plate located on one side of the linkage block is fixedly installed on the support column. A moving shaft is fixedly installed on the side of the linkage block facing the positioning plate. The end of the moving shaft away from the linkage block passes through the positioning plate and is fixedly connected to the moving block. A spring located between the linkage block and the positioning plate is movably fitted on the moving shaft.

[0015] Furthermore, the movable block has a through groove, and an insulating sleeve is fixedly installed on one side of the through groove. The upper and lower ends of the insulating sleeve are flush with the upper and lower ends of the movable block, respectively. A conductive block is fixedly installed in the middle of the insulating sleeve, and both ends of the conductive block extend out of the insulating sleeve. An L-shaped fixing plate I is fixedly installed on the positioning plate, located on one side of the movable block. An adjustment device facing the movable block is fixedly installed on the L-shaped fixing plate I. Two conductive springs are fixedly installed on the adjustment device. The two conductive springs are movably connected to both ends of the conductive block, and one end of the two conductive springs is electrically connected to the indicator light and the power supply through wires. The power supply and the indicator light are both fixedly installed on the L-shaped mounting plate. The L-shaped mounting plate is fixed to the support column by bolts.

[0016] Furthermore, the adjusting device includes two L-shaped fixing plates II, which are respectively fixedly installed at both ends of the L-shaped fixing plate I, and the L-shaped fixing plates II do not contact the moving block. A lead screw is movably fitted between the two L-shaped fixing plates II, and a moving part is threaded onto the lead screw. Insulating blocks are fixedly installed at both ends of the moving part, and the insulating blocks are respectively fixedly sleeved with two conductive reeds. One end of the lead screw extends out of the outside of one of the L-shaped fixing plates II and is fixedly connected to an adjusting wheel. Limiting rods located on both sides of the lead screw are fixedly installed between the two L-shaped fixing plates II, and both limiting rods are movably sleeved with the moving part.

[0017] The beneficial effects of this invention are:

[0018] 1. This application provides an automatic loading and unloading vehicle for new energy battery frames. By setting positioning frames in the loading and unloading areas, one end of the vehicle body is pushed into the positioning frame for unloading and storing battery frames or retrieving them. Each layer of the supporting mechanism is rotated around the positioning support shaft under the gravity of the gravity block, without affecting the unloading or retrieval of the next layer of battery frames. This improves the efficiency of loading and unloading battery frames. It eliminates the traditional cylinder mechanism and complex electronic control structure, and does not require other linkage mechanisms to achieve this effect. This makes the structure simple, less prone to failure, saves costs, and is convenient to use.

[0019] 2. The guide wheels on the positioning frame, along with the beveled design at both ends of the material cart body, make it easy for operators to push the material cart body into the positioning frame. The positioning frame is used to position the material cart body, allowing it to store materials in the unloading area or retrieve materials in the loading area.

[0020] 3. A guide rod is installed at one end of the material cart body, and a limit block corresponding to the guide rod is installed on one side of the positioning frame. After the operator pushes one end of the material cart body into the inside of the positioning frame, the guide wheel inside the positioning frame guides it until the guide rod moves to contact the limit block. The limit block limits the guide rod, further improving the positioning effect of the material cart body and correcting the deviation of the material cart body moving into the positioning frame, so as to ensure that the machine gripper can accurately feed or pick up materials.

[0021] 4. A swing cylinder that drives the passive plate to move and rotate is set on the positioning frame. In conjunction with the anti-misoperation plate set on the material cart body, and the anti-misoperation plate is set close to the middle of the material cart body, the anti-misoperation design of the anti-misoperation plate being set off from the center of the material cart body prevents the operator from pushing the material cart body in the wrong direction, which would cause the product to be in the wrong direction.

[0022] 5. By opening transverse guide grooves on the support columns that are compatible with the positioning support shaft, and in conjunction with the structural design of the material support mechanism, the weight of the battery frame is used to push the material support mechanism to move as a whole during the unloading and storage process. The length error of the battery frame can then be judged based on the moving distance of the material support mechanism, thereby detecting unqualified battery frames in advance and improving the production efficiency of battery frames.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0045] Example 1

[0046] Please see Figures 1-2 An automatic loading and unloading cart for new energy battery frames includes a cart body 1 for storing battery frames 2 and a positioning frame 3 for positioning the cart body 1. The positioning frame 3 is set in the loading area and the unloading area. The positioning frame 3 is U-shaped and has several guide wheels 4 on its inner side. The number of guide wheels 4 is not less than two. Both ends of the cart body 1 are provided with guide ramps. With the guidance of the guide wheels 4 on the inner side of the positioning frame 3, it is convenient for the operator to push the cart body 1 into the positioning frame 3. The positioning frame 3 is used to position the cart body 1 so that the battery frames 2 can be unloaded and transported to the cart body 1 after production, or retrieved from the cart body 1.

[0047] Please see Figures 2-3Guide blocks 5 are fixedly installed on both sides of one end of the material cart body 1. A guide rod 6 is fixedly installed in the middle of the side of the guide block 5 away from the material cart body 1. The end of the guide rod 6 away from the guide block 5 is spherical. A limiting block 7 corresponding to the guide rod 6 is fixedly installed on the side of the positioning frame 3 facing the material cart body 1. A groove is opened on the side of the limiting block 7 away from the positioning frame 3. The groove width decreases uniformly from the outside to the inside, and the innermost side of the groove is adapted to the guide rod 6. After the operator pushes one end of the material cart body 1 into the inside of the positioning frame 3, the guide wheel 4 inside the positioning frame 3 guides it until the guide rod 6 moves to contact the limiting block 7. The limiting effect of the limiting block 7 on the guide rod 6 further improves the positioning effect of the material cart body 1, making it easier for the machine gripper to accurately place the battery frame 2 on or remove it from the material cart body 1.

[0048] Please see Figures 2-5 Anti-misalignment plates 8 are fixedly installed on the top of both ends of the material cart body 1. The anti-misalignment plates 8 are close to the middle of the material cart body 1, and a limit groove is opened in the middle of the anti-misalignment plate 8. A positioning mounting plate 9 located on one side of the anti-misalignment plate 8 is fixedly installed on the positioning frame 3. A swing cylinder 10 facing the anti-misalignment plate 8 is fixedly installed on the positioning mounting plate 9. The output shaft of the swing cylinder 10 extends to one side of the limit groove and is fixedly connected to a passive plate 11. The height of the passive plate 11 is less than the height of the limit groove, and the height of the passive plate 11 is greater than the width of the limit groove. A contact sensor 12 located on one side of one of the limit blocks 7 is fixedly installed on the positioning frame 3. When the operator pushes one end of the material cart body 1 into the positioning frame 3, the anti-misalignment plate 8 is exactly aligned with the passive plate 11. After the guide rod 6 contacts and aligns with the limit block 7, the contact sensor 12 will detect contact with the material cart body 1. The swing cylinder 10 drives the output shaft to rotate the passive plate 11 half a turn and pull it back, so that the passive plate 11 limits the anti-fool plate 8, thereby limiting the entire material cart body 1 and preventing the material cart body 1 from moving during loading or unloading. When the operator pushes the other end of the material cart body 1 into the positioning frame 3, because the anti-fool plate 8 is off-center from the center of the material cart body 1, the anti-fool plate 8 and the passive plate 11 will be misaligned. The passive plate 11 blocks the anti-fool plate 8, so that the material cart body 1 can no longer move to the inside of the positioning frame 3. Through the anti-fool design, the problem of the product orientation being incorrect is avoided by the operator pushing the material cart body 1 in the wrong direction.

[0049] Please see Figure 1 , Figures 6-9Support columns 13 are fixedly installed at both ends of the top of the material cart body 1, and the four support columns 13 are respectively close to the four corners of the top of the material cart body 1. Several positioning support shafts 14 are fixedly installed on the support columns 13. The number of positioning support shafts 14 is not less than two, and the several positioning support shafts 14 are arranged longitudinally at equal intervals on the support columns 13. Each positioning support shaft 14 is movably fitted with a material support mechanism 15. The material support mechanism 15 includes a guide block 151 movably fitted on the positioning support shaft 14. One end of the guide block 151 is connected to a support block 152. The support block 152 faces the inside of the material cart body 1 and is used to support the battery frame 2. The guide block 151 faces the support. One side of block 152 is designed with a slope so that when the battery frame 2 is placed on the material cart body 1, the slope of guide block 151 can guide the battery frame 2 to be placed on support block 152 and supported by support block 152. The end of guide block 151 away from support block 152 is connected to gravity block 153. The gravity of gravity block 153 ensures that the upper material support mechanism 15 will not affect the lower material support mechanism 15 when the battery frame 2 is placed on the lower material support mechanism 15, so that the battery frame 2 can be placed from the lower material support mechanism 15 upwards. Guide block 151, support block 152 and gravity block 153 are integrally molded to improve the overall strength of material support mechanism 15 and thus improve the support effect.

[0050] Several limiting shafts 16 are fixedly installed on the support column 13. There are no fewer than two limiting shafts 16. The limiting shafts 16 are arranged longitudinally at equal intervals on the support column 13 and are located on one side of the positioning support shaft 14. The limiting shafts 16 support the material support mechanism 15 to ensure that after the battery frame 2 is placed on the support block 152, the support block 152 is in a horizontal state, which forms a stable support effect for the battery frame 2. A limiting shaft 17 is fixedly installed on the support column 13, located diagonally below the bottom limiting shaft 16 on the support column 13 and on the other side of the positioning support shaft 14. The bottom of the gravity block 153 near the guide block 151 has a slot that matches the limiting shaft 16, so that when the material support mechanism 15 is retracted to the inside of the support column 13, it just hits the limiting shaft 16. When the material support mechanism 15 supports the battery frame 2, the limiting shaft 16 just supports the material support mechanism 15.

[0051] Please refer to the following for details. Figures 8-9 At this time, by utilizing the obstruction of the limiting shaft 17, the support block 152 at one end of the supporting mechanism 15 remains on one side of the supporting column 13, and the other supporting mechanisms 15 above this supporting mechanism 15 will not affect the placement of the battery frame 2. After the first battery frame 2 is placed on the supporting mechanism 15 at the bottom of the supporting column 13, the support block 152 at one end of the supporting mechanism 15 will become as follows. Figure 7As shown in the horizontal position, the gravity block 153 at the other end of the supporting mechanism 15 pushes against the gravity block 153 above it and rotates around the positioning support shaft 14, causing the second layer supporting mechanism 15 to rotate as a whole from bottom to top. The support block 152 at one end of the second layer supporting mechanism 15 rotates to one side of the support column 13, so that the second battery frame 2 can be placed on the second layer supporting mechanism 15. Similarly, the battery frames 2 can be placed on each layer of supporting mechanism 15 in sequence, thereby improving the efficiency of material unloading and transfer. When picking up materials, the most... After the top battery frame 2 is removed, the top supporting mechanism 15 rotates under the gravity of the gravity block 153 at one end, thereby removing the second battery frame 2 from top to bottom. Similarly, each battery frame 2 can be removed from top to bottom, so that the supporting mechanism 15 of each layer will not affect the removal and placement of the next battery frame 2. The traditional cylinder mechanism and complex electronic control structure are eliminated, and no other linkage mechanism is needed to achieve this effect. This makes the structure simple, less prone to failure, saves costs, and is convenient to use.

[0052] Please see Figures 1-2 A column 18 is fixedly installed on the positioning frame 3. The same number of material sensors 19 as the material support mechanism 15 on the support column 13 are fixedly installed on the column 18. Each layer of material sensors 19 corresponds one-to-one with each layer of material support mechanism 15 on the support column 13. By setting the material sensors 19, the loading and unloading status of the battery frame 2 can be determined so as to realize PCL interaction.

[0053] Example 2

[0054] Please see Figure 10-14Based on Embodiment 1, but differing from Embodiment 1, two support columns 13 at one top end of the material cart body 1 are respectively provided with transverse guide grooves 131 adapted to the positioning support shaft 14, allowing the positioning support shaft 14 to move horizontally within the support columns 13. A baffle 20 is movably fitted on the positioning support shaft 14 away from the material supporting mechanism 15, located between the support columns 13 and the material supporting mechanism 15. The two sides of the baffle 20 are respectively attached to one side of the material supporting mechanism 15 and one side of the support column 13. A linkage block 21 is fixedly connected to the end of the positioning support shaft 14 away from the material supporting mechanism 15. One side of the linkage block 21 is attached to the other side of the support column 13. By using the linkage block 21 and the baffle 20 on the positioning support shaft 14 to attach to both sides of the support column 13, the positioning support shaft 14 can move horizontally stably in the transverse guide grooves 131. A positioning plate 22 is fixedly installed on one side of the linkage block 21. A moving shaft 23 is fixedly installed on the side of the linkage block 21 facing the positioning plate 22. The end of the moving shaft 23 away from the linkage block 21 passes through the positioning plate 22 and is fixedly connected to the moving block 24. A spring 25 is movably mounted on the moving shaft 23 between the linkage block 21 and the positioning plate 22. Under normal conditions, the positioning support shaft 14 in the transverse guide groove 131 tends to be close to the limit shaft 16. When placing the battery frame 2, the inclined surface design of the guide block 151, combined with the weight of the battery frame 2, will make the battery frame 2 horizontal, overcoming the elastic force of the spring 25 on the linkage block 21, and pushing the entire material support mechanism 15 and the positioning support shaft 14 to move, so as to compensate for the length accuracy difference of the battery frame 2 after production.

[0055] Please see Figures 14-17 A through groove is provided on the movable block 24. An insulating sleeve 26 is fixedly installed on one side of the through groove. The upper and lower ends of the insulating sleeve 26 are flush with the upper and lower ends of the movable block 24, respectively. A conductive block 27 is fixedly installed in the middle of the insulating sleeve 26, and both ends of the conductive block 27 extend out of the outside of the insulating sleeve 26. An L-shaped fixing plate I 28 located on one side of the movable block 24 is fixedly installed on the positioning plate 22. An adjusting device 29 facing the movable block 24 is fixedly installed on the L-shaped fixing plate I 28. Two conductive springs 30 are fixedly installed on the adjusting device 29. The two conductive springs 30 are movably connected to both ends of the conductive block 27, and one end of the two conductive springs 30 is electrically connected to the indicator light 31 and the power supply through wires. The power supply and the indicator light 31 are both fixedly installed on the L-shaped mounting plate 32. The L-shaped mounting plate 32 is fixed to the support column 13 by bolts.

[0056] When placing the battery frame 2, the inclined design of the guide block 151, combined with the weight of the battery frame 2 itself, ensures that the battery frame 2 is placed horizontally. This overcomes the elastic force of the spring 25 on the linkage block 21, pushing the entire support mechanism 15 and the positioning support shaft 14 to move. The positioning support shaft 14 then moves the linkage block 21 towards the positioning plate 22, causing the conductive block 27 to contact the conductive reed switch 30. The indicator light 31 is then energized and illuminates. The thickness of the conductive block 27 is set within the allowable error range of the battery frame 2's length. That is, when the linkage block 21 moves towards the positioning plate 22, the conductive block 27 contacts the conductive reed switch 30. If the electric block 27 does not move to contact the conductive reed switch 30, the conductive reed switch 30 is not energized and remains in an off state. At this time, the operator can know that the length of the battery frame 2 is too small. When the linkage block 21 moves toward the positioning plate 22, the conductive block 27 moves from one side of the conductive reed switch 30 to the other side. The conductive reed switch 30 lights up and then goes out. At this time, the operator can know that the length of the battery frame 2 is too large. This makes it easier for the operator to know whether the length of the battery frame 2 meets the required accuracy requirements, so as to eliminate unqualified products in advance and further improve the production efficiency of the battery frame 2.

[0057] The adjusting device 29 includes two L-shaped fixing plates II 291, which are respectively fixedly installed at both ends of the L-shaped fixing plate I 28. The L-shaped fixing plates II 291 do not contact the moving block 24, so that the L-shaped fixing plates II 291 do not affect the movement of the moving block 24. A lead screw 292 is movably fitted between the two L-shaped fixing plates II 291. A moving part 293 is threaded onto the lead screw 292. Insulating blocks 294 are fixedly installed at both ends of the moving part 293. The insulating blocks 294 are respectively fixedly sleeved with two conductive reeds 30. One end of the lead screw 292 extends out from one of the reeds. An adjusting wheel 295 is fixedly connected to the outside of the L-shaped fixing plate II 291. Limiting rods 296 located on both sides of the lead screw 292 are fixedly installed between the two L-shaped fixing plates II 291. Both limiting rods 296 are movably sleeved with the moving part 293. By using the limiting action of the two limiting rods 296 on the moving part 293, the position of the moving part 293 can be adjusted by rotating the adjusting wheel 295 to drive the lead screw 292 to rotate. This adjusts the horizontal distance between the conductive reed 30 and the conductive block 27 in the initial state, so that specific adjustments can be made according to different lengths of the battery frame 2, thus improving practicality.
