Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, and in particular to a foam feeding mechanism for new energy vehicles. Background Technology

[0002] In the field of new energy vehicles, foam mainly undertakes four core functions: sealing and waterproofing, cushioning and shock absorption, heat insulation and flame retardancy, and support and protection. These functions are directly related to the battery safety and overall vehicle reliability of new energy vehicles.

[0003] In the automated production process of foam for new energy vehicle batteries, the foam needs to go through the process of "conveyor belt feeding → positioning → drilling → return". This method first requires the use of gantry crane grippers to clamp and move the foam from the conveyor belt to the worktable. Then, the drilling components on the worktable are used to position and drill holes in the foam. After drilling is completed, the gantry crane grippers are used again to clamp and move the foam back onto the conveyor belt. This process is repeated to feed the foam.

[0004] Traditional gantry cranes typically use electrically powered grippers, which are costly in terms of hardware. Components such as precision reducers and high-precision sensors are expensive, and they also require additional power during operation, further increasing costs. Therefore, there is an urgent need for a lower-cost feeding mechanism for processing foam used in new energy vehicle batteries. Summary of the Invention

Detailed Implementation

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] See Figure 1-3 A workbench 11 is provided on one side of the conveying mechanism 1. A gantry frame 12 is provided above the conveying mechanism 1 and the workbench 11. A movable component 13 is provided on the gantry frame 12. The gripper platform 3 is installed at the bottom of the movable component 13 and moves through the movable component 13.

[0045] Multiple positioning plates 2 are installed on the conveying mechanism 1, and all positioning plates 2 are moved by the conveying mechanism 1. One positioning plate 2 is fixedly installed on the worktable 11. During operation, the conveying mechanism 1 conveys the positioning plate 2 to the bottom of the gantry frame 12, and then the conveying mechanism 1 stops conveying. At this time, the foam workpiece on the positioning plate 2 of the conveying mechanism 1 is clamped and moved to the positioning plate 2 on the worktable 11 by the movable component 13 and the gripper platform 3. Then, the drilling component on the worktable 11 is used to position and drill holes in the foam workpiece. After the drilling is completed, the foam workpiece is moved back to the positioning plate 2 on the conveying mechanism 1 by the gripper platform 3. Then, the next positioning plate 2 is moved to the bottom of the gantry frame 12 by the conveying mechanism 1, and so on, to realize the loading and unloading of foam workpieces.

[0046] It is worth noting that a drilling mechanism in the prior art can be installed on the worktable 11. The drilling mechanism in the prior art can automatically position and drill holes in the foam workpiece on the worktable 11. The conveying mechanism 1, the drilling mechanism, the gantry 12 and the movable component 13 are all prior art and do not belong to the cost-saving technical problem that needs to be solved in this technical solution, so they will not be described in detail.

[0047] Among them, the positioning plate 2 is provided with support rod grooves 22 corresponding to the support rods 323, the positioning plate 2 is provided with positioning parts 23 corresponding to the foam workpiece, and multiple columns 21 are fixedly installed on the positioning plate 2, and the top of each column 21 is fixedly provided with a fixing magnetic part 211.

[0048] See Figure 3-13 Multiple guide posts 35 are fixedly installed on both sides of the top of the gripper platform 3. The top of each guide post 35 is connected to the top plate 36. An upper magnetic plate 361 is fixedly installed in the middle of the top plate 36. The movable plates 4 are guided to move by the guide posts 35. A lower magnetic plate 41 that is compatible with and attracted to the upper magnetic plate 361 is fixedly installed in the middle of each movable plate 4.

[0049] Limiting rings are fixedly installed on the outer side of the guide column 35. By setting the limiting rings, the movable plate 4 can be magnetically attracted to the top plate 36 when it moves to the highest position, but it will not come into contact with the top plate 36, so that the magnetic shielding plate 34 can be inserted between the lower magnetic plate 41 and the upper magnetic plate 361.

[0050] The top of each support column 33 is fixedly provided with a guide member 331. The magnetic shielding plate 34 is guided to move by the guide member 331. The middle part of the magnetic shielding plate 34 is adapted to the guide member 331 to provide a guide cavity 341. Side rods 342 are fixedly provided on both sides of the magnetic shielding plate 34, and the ends of the side rods 342 are provided with side magnetic members 343.

[0051] The matching arrangement between the guide member 331 and the guide cavity 341 allows the magnetic shielding plate 34 to move stably on the support column 33. By inserting the magnetic shielding plate 34 between the lower magnetic plate 41 and the upper magnetic plate 361, the magnetic attraction between the lower magnetic plate 41 and the upper magnetic plate 361 can be weakened, at which point the movable plate 4 can fall automatically under gravity. The magnetic shielding plate 34 is existing technology and will not be described in detail.

[0052] Support columns 33 are only provided on the movable grippers 32 on both sides where the distance between them is relatively large; support columns 33 are not provided on the other movable grippers 32. The magnetic shielding plate 34 can be moved by the side magnetic components 343 on both sides of the magnetic shielding plate 34.

[0053] The movable plate 4 is provided with fixed seats 45 on both sides. The bottom of each fixed seat 45 is fixedly provided with a vertical rod 451. Each vertical rod 451 is fitted with a movable limiting member 452. The inner wall of each limiting member 452 is provided with a damping pad. The limiting member 452 is located between the side magnetic member 343 and the fixed magnetic member 211. Furthermore, a support block 37 is fixedly provided on the gripper platform 3 below the limiting member 452.

[0054] When the movable plate 4 is at the bottom, the limiting member 452 is supported on the upper end of the vertical rod 451 by the support block 37. When the movable plate 4 moves upward, it drives the fixed base 45, the vertical rod 451, and the limiting member 452 to move upward synchronously. At this time, the support block 37 no longer supports the limiting member 452, and the limiting member 452 can fall automatically under its own weight. Furthermore, the damping pad on the inner wall of the limiting member 452 can slow down the falling speed of the limiting member 452 on the vertical rod 451, so that the limiting member 452 takes about ten seconds to move to the bottom. It is worth noting that the damping pad is existing technology, so it will not be described in detail.

[0055] Among them, multiple connecting rods 43 are fixedly connected between the two movable plates 4. The outermost connecting rod 43 is provided with a reset groove 431 that is adapted to the elastic clip 38. A reset magnetic component 381 is fixedly provided behind the elastic clip 38, and the reset magnetic component 381 is adapted to and attracted to the fixed magnetic component 211.

[0056] When the movable plate 4 moves to the bottom, the elastic clips 38 all pass through the reset slots 431 and automatically lock onto the top of the connecting rod 43. When the gripper platform 3 falls onto the positioning plate 2, the elastic clips 38 all move synchronously to one side of the fixed magnetic component 211. At this time, the reset magnetic component 381 on the elastic clip 38 can move towards the fixed magnetic component 211 by magnetic attraction. In this way, the elastic clips 38 can be pulled and bent towards the reset slots 431 by magnetic attraction, thereby releasing the elastic clips 38 from locking the connecting rod 43.

[0057] Multiple fixing plates 44 are fixedly installed outward on the outer side of the connecting rod 43. A spring 441 is installed downward on the bottom of each fixing plate 44, and the other end of each spring 441 is connected to the base plate 442. An anti-falling post 443 is fixedly installed vertically upward on the top of each base plate 442. The anti-falling post 443 passes through the spring 441 and the fixing plate 44, and an anti-falling component is fixedly installed on the top of each anti-falling post 443.

[0058] By setting up the anti-fall-off column 443 and the anti-fall-off component, it can be ensured that the base plate 442 is stably located below the fixed plate 44 and moves vertically, and the base plate 442 is prevented from falling off the fixed plate 44.

[0059] See Figure 14-20The gripper platform 3 has movable cavities 31 on both sides, and movable grippers 32 are adapted to move within the movable cavities 31. A gripping rod is provided downwards on the outer side of each movable gripper 32, and a support rod 323 is fixedly installed at the bottom of each gripping rod. Multiple guide blocks are provided on the inner wall of each movable cavity 31, and guide grooves are provided on each movable gripper 32 corresponding to the guide blocks. This adaptation between the guide blocks and guide grooves not only improves the stability of the movable grippers 32 during movement but also prevents the movable grippers 32 from falling out of the movable cavity 31.

[0060] The top of each movable gripper 32 is provided with a first inclined surface 321, and the bottom of each pressure block 42 is provided with a second inclined surface 421 corresponding to the first inclined surface 321. This allows the movable gripper 32 to be pushed outward by the adaptation between the first inclined surface 321 and the second inclined surface 421 when the pressure block 42 moves downward, thereby opening the movable gripper 32.

[0061] Each movable gripper 32 has a first groove 322, and the bottom of the pressure block 42 has a second groove 422 corresponding to the first groove 322. The first groove 322 and the second groove 422 are connected by a traction rope 423, and a fixed guide rope ring 311 is provided in the movable cavity 31 corresponding to the traction rope 423. When the pressure block 42 moves upward, it can pull the movable gripper 32 inward through the traction rope 423, thereby clamping the foam workpiece through the movable gripper 32. Furthermore, the guide rope ring 311 is provided in the movable cavity 31 corresponding to the traction rope 423 to ensure the stability of the traction rope 423 when pulled.

[0062] In this embodiment, during the process of feeding and punching foam workpieces, the positioning plate 2 is first moved to the bottom of the gantry frame 12 by the conveying mechanism 1. Then the conveying mechanism 1 stops conveying. At this time, the movable component 13 on the gantry frame 12 drives the gripper platform 3 to move above the positioning plate 2 on the conveying mechanism 1 and move downward.

[0063] As the gripper platform 3 moves downward, multiple base plates 442 on both sides come into contact with the positioning plate 2. Subsequently, the gripper platform 3 continues to move downward, and the springs 441 above the base plates 442 are all compressed.

[0064] When the gripper platform 3 moves downward to its lowest point, it is positioned at the top of the foam workpiece and in contact with it. At this time, the support rods 323 at the bottom of the movable gripper 32 pass through the side of the foam workpiece and are inserted into the support rod groove 22. Furthermore, the elastic clips 38 are adapted to move to one side of the fixed magnetic component 211. At this point, the reset magnetic component 381 on the elastic clip 38 can move towards the fixed magnetic component 211 through magnetic attraction, causing the elastic clip 38 to bend outward towards the reset groove 431, thereby releasing the elastic clip 38 from locking the connecting rod 43.

[0065] At this point, the connecting rod 43 and the movable plates 4 on both sides are no longer limited by the elastic retainer 38. The compressed spring 441 can then push upwards using its own elastic force, thereby driving the connecting rod 43 and the movable plates 4 to move upwards. As the movable plates 4 move upwards, the distance between them and the top plate 36 decreases. At this time, the distance between the lower magnetic plate 41 and the upper magnetic plate 361 decreases, and the magnetic attraction increases. Thus, the movable plates 4 can be attracted upwards by the magnetic attraction.

[0066] As the movable plate 4 moves upward, it drives the pressure block 42 to move upward synchronously. This allows the movable gripper 32 to be pulled inward by the traction rope 423. At this time, the foam workpiece can be clamped by the clamping rod on the movable gripper 32, and the foam workpiece can be supported by the support rod 323 at the bottom of the movable gripper 32.

[0067] As the movable gripper 32 moves inward, it can drive the support columns 33, magnetic shielding plate 34 and side magnetic component 343 on both sides to move inward synchronously. However, since the magnetic shielding plate 34 is located outside the support column 33, the magnetic shielding plate 34 is not located between the lower magnetic plate 41 and the upper magnetic plate 361 at this time.

[0068] When the movable gripper 32 moves completely to its innermost position, the side magnetic component 343 moves to the adsorption distance between itself and the fixed magnetic component 211, at which point the side magnetic component 343 can be adsorbed by the fixed magnetic component 211. However, as the movable plate 4 moves upward, it drives the fixed base 45, the vertical rod 451, and the limiting component 452 to move upward synchronously. Furthermore, the damping pad prevents the limiting component 452 from falling slowly. Therefore, the limiting component 452 prevents the side magnetic component 343 from being adsorbed by the fixed magnetic component 211, and the magnetic shielding plate 34 will not move between the lower magnetic plate 41 and the upper magnetic plate 361.

[0069] It is worth noting that before the limiting member 452 falls to the bottom, the limiting member 452 can be locked on the outside of the side magnetic member 343 to prevent it from moving, and the total falling time of the limiting member 452 is about ten seconds.

[0070] Before the limiting member 452 falls to the bottom, the movable component 13 drives the gripper platform 3 to move upward, thereby clamping the foam workpiece. When the gripper platform 3 moves upward, the side magnetic component 343 is no longer within the adsorption distance of the fixed magnetic component 211. At this time, even if the limiting member 452 falls to the lowest point, the side magnetic component 343 will not be attracted or moved.

[0071] Furthermore, by moving the movable component 13 on the gantry 12, the gripper platform 3 can be moved above the positioning plate 2 on the worktable 11. It is worth noting that the conveying mechanism 1 and the positioning plate 2 on the worktable 11 have the same structure.

[0072] As the movable component 13 moves the gripper platform 3 downwards, the movable plate 4 is positioned above and attracted by the top plate 36. Therefore, the springs 441 on the bottom plates 442 on both sides of the movable plate 4 are not compressed. When the gripper platform 3 reaches its lowest point, the limiting member 452 has already fallen to the bottom and no longer blocks the outside of the side magnetic member 343. At this point, the side magnetic member 343 can move towards the fixed magnetic member 211 through magnetic attraction, and drive the magnetic shielding plate 34 to move synchronously, so that the magnetic shielding plate 34 moves between the lower magnetic plate 41 and the upper magnetic plate 361.

[0073] At this point, the magnetic force is blocked by the magnetic shielding plate 34, which greatly reduces the magnetic attraction between the lower magnetic plate 41 and the upper magnetic plate 361. The movable plate 4 can then fall automatically under gravity. During the descent of the movable plate 4, the pressure block 42 moves downwards simultaneously, thereby pressing the first inclined surface 321 of the movable gripper 32 against the second inclined surface 421 on the pressure block 42, thus squeezing the movable gripper 32 outwards.

[0074] Although the pressure block 42 is hindered by the elastic force of the spring 441 during its downward movement, the support rod 323 at the bottom of the movable jaw 32 is short. Therefore, the support rod 323 can move to the outside of the foam workpiece when the pressure block 42 moves down two-thirds of the distance. At this time, the movable jaw 32 no longer clamps the foam workpiece.

[0075] Then, the gripper platform 3 can be moved upward by the movable component 13, at which point the foam workpiece can be stably placed on the positioning plate 2 on the worktable 11.

[0076] As the gripper platform 3 moves upward, the spring 441 gradually returns to its normal state. At this time, the movable plate 4 and the pressure block 42 can continue to move downward until the bottom plate 442 no longer contacts the positioning plate 2. The movable plate 4 then moves to the bottom, at which point the movable grippers 32 are completely pushed out. The elastic clips 38 on the gripper platform 3 can then lock the connecting rod 43 again, fixing the movable plate 4 at the bottom and thus achieving the reset of the movable plate 4.

[0077] The foam workpiece can then be punched using the punching assembly on the worktable 11. After punching, the foam workpiece can be transferred to the positioning plate 2 on the conveying mechanism 1 using the same steps. The conveying mechanism 1 is then activated to move the next positioning plate 2 to the bottom of the gantry 12 for loading and processing the next foam workpiece.

[0078] Furthermore, the gripper platform 3 in this application has two states. In the first state, the movable gripper 32 on the gripper platform 3 is open. When the gripper platform 3 moves to the positioning plate 2, the movable gripper 32 automatically closes to clamp the foam workpiece. At this time, the gripper platform 3 switches to the second state.

[0079] In the second state, the movable jaws 32 on the gripper platform 3 are gripping and transferring the foam workpiece, so the movable jaws 32 are all in an inwardly retracted and closed state. When the gripper platform 3 moves onto the positioning plate 2, the movable jaws 32 open to place the foam workpiece on the positioning plate 2, and at this time the gripper platform 3 switches back to the first state.

[0080] Furthermore, in the first state, the movable plates 4 on the gripper platform 3 are all located at the bottom and are held in place by the elastic locking element 38. At this time, the movable gripper 32 is in the open state due to the pressure of the pressure block 42. When the gripper platform 3 moves downward, since the movable plates 4 are located at the bottom, the height of the bottom plate 442 is lower, and the spring 441 can be compressed. When the gripper platform 3 moves to the bottom, the elastic locking element 38 automatically releases the locking of the connecting rod 43 through the setting of the fixing magnetic element 211. At this time, the movable plates 4 and the connecting rod 43 can move upward by the elastic force of the spring 441 and the magnetic attraction of the upper magnetic plate 361, so that the movable gripper 32 can be pulled inward by the traction rope 423. At this time, the movable gripper 32 is in the clamping state, and the gripper platform 3 switches to the second state.

[0081] Furthermore, in the second state, the movable plates 4 are all positioned above and attracted by the top plate 36, and the movable grippers 32 are all in a clamping state. When the gripper platform 3 moves downward, since the movable plates 4 are positioned above, the bottom plate 442 is at a higher height, and the spring 441 will not be compressed. When the gripper platform 3 moves to the bottom, the side magnetic component 343 can move towards the fixed magnetic component 211 through magnetic attraction, thereby driving the magnetic isolation plate 34 to move between the upper magnetic plate 361 and the lower magnetic plate 41. At this time, the magnetic attraction between the lower magnetic plate 41 and the upper magnetic plate 361 weakens, and the movable plates 4 can fall under their own weight, thereby pushing the movable grippers 32 outward by the downward movement of the pressure block 42. At this time, the movable grippers 32 are in an open state due to the pressure of the pressure block 42, and the gripper platform 3 switches back to the first state.

[0082] Furthermore, the support block 37 can support the limiting member 452. When the limiting member 452 is at the bottom, it will not jam the side magnetic member 343. At this time, the side magnetic member 343 can move towards the fixed magnetic member 211 by magnetic attraction. And with the setting of the support block 37, when the movable plate 4 moves downward, the limiting member 452 can be moved and reset to the upper end of the vertical rod 451.

[0083] When the gripper platform 3 switches to the second state, the movable plate 4 has just moved to its highest position. At this time, the fixed base 45, the vertical rod 451, and the limiting member 452 are all at their highest positions. Because the inner wall of the limiting member 452 is equipped with a damping pad as in the prior art, its falling speed can be slowed when it reaches its highest position. Furthermore, during the falling process, the limiting member 452 can engage with one side of the side magnetic member 343, preventing the side magnetic member 343 from moving towards the fixed magnetic member 211 by magnetic attraction.

[0084] When the gripper platform 3 moves to the positioning plate 2 on the other side, the limiting member 452 has enough time to fall to the bottom. At this time, the side magnetic member 343 is no longer stuck by the limiting member 452, and the side magnetic member 343 can move towards the fixed magnetic member 211 by magnetic attraction, so as to drive the magnetic shielding plate 34 to move synchronously.

[0085] Furthermore, the clamping components in this device have lower procurement costs compared to the precision reducers and high-precision sensors in electric grippers, and no electric clamping is required during subsequent operations, thus saving costs.

[0086] In this invention, both the conveying mechanism 1 and the worktable 11 are equipped with positioning plates 2. The movable plate 4 moves vertically on the gripper platform 3, and with the fixed magnetic component 211 on the positioning plate 2, the opening and clamping of the movable gripper 32 can be controlled, thereby transferring the foam workpiece from one side of the positioning plate 2 to the other side. When the device is used to clamp and transfer foam, the clamping mechanism does not require additional power, thus saving costs.

[0087] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
