Description

Technical Field

[0001] This invention relates to the field of battery module technology, and in particular to a low-cost CTP battery module rapid positioning tooling device. Background Technology

[0002] With the iterative upgrade of new energy power battery technology, CTP (Cell To Pack) technology, which directly integrates cells into battery packs, has become the mainstream solution for mass production of power batteries. Unlike the traditional three-level assembly structure of "cell-module-battery pack," CTP battery modules eliminate auxiliary structures such as traditional module end plates and side plates, directly integrating cells to form an integral battery module, which is then assembled into the PACK housing. This approach boasts core advantages such as high space utilization, high energy density, fewer components, and low production costs, and is widely used in new energy passenger vehicles, energy storage equipment, and other fields.

[0003] In the mass production assembly process of CTP battery modules, to ensure the connection strength, structural stability, and thermal conductivity of the CTP battery module and the PACK housing, the industry generally adopts an adhesive bonding process. The specific assembly process is as follows: First, structural adhesive and thermally conductive adhesive are evenly applied to the bottom of the PACK housing. Then, the molded CTP battery module is placed as a whole on the adhesive application area of ​​the PACK housing using hoisting equipment, so that the bottom of the CTP battery module is fully adhered to the adhesive. After the adhesive cures, the CTP battery module and the PACK housing are integrated and fixedly assembled.

[0004] Currently, there are significant process defects and equipment limitations in the CTP battery module stacking and assembly process. CTP battery modules are large-sized, integrated structures with significant weight and high dimensional accuracy requirements. During actual hoisting and stacking, they are highly susceptible to factors such as equipment hoisting deviations, incoming material dimensional tolerances, workstation vibrations, and human error, leading to assembly errors such as shifts in stacking position, angular deviations, and misalignments. Furthermore, because the CTP battery modules directly contact the uncured adhesive on the bottom of the housing after stacking, and the adhesive has immediate tack, once the module is in place and contacts the adhesive surface, it quickly adheres and fixes itself, preventing free sliding, fine-tuning, and posture correction.

[0005] Currently available positioning fixtures have a limited design, mostly consisting of simple fixed limiting structures. These can only provide coarse positioning guidance before the CTP battery module is unloaded, and cannot accurately correct or calibrate the position of the CTP battery module after it has been positioned and bonded. If there are assembly errors in the CTP battery module, it can only be forcibly lifted and reassembled. This not only damages the adhesive layer on the casing surface, causing problems such as excess adhesive, insufficient adhesive, and uneven adhesive thickness, resulting in significant waste of adhesive material, but also easily leads to quality defects such as cell impacts, terminal damage, and overall module deformation, greatly increasing the product defect rate. Furthermore, the repeated lifting, adhesive removal, re-application, and reassembly processes significantly increase the complexity of the process, severely reducing the production cycle and efficiency of CTP battery module assembly. Summary of the Invention

[0006] Given that existing technologies suffer from problems such as a single tooling positioning structure, only coarse positioning, easy displacement and deflection errors in module stacking, inability to fine-tune and correct deviations after placement, easy damage to adhesive layer and module during rework, resulting in material waste, high product defect rate, cumbersome processes and low production efficiency, a low-cost CTP battery module rapid positioning tooling equipment is proposed.

[0007] This application provides a low-cost CTP battery module rapid positioning tooling equipment, the purpose of which is to solve the pain points of poor alignment accuracy and inability to correct deviations after assembly of existing CTP battery modules, avoid material loss and module damage caused by rework, simplify assembly process, reduce product defect rate, and improve assembly accuracy and production cycle time, thereby optimizing mass production assembly process with low cost structure.

[0008] The technical solution of the present invention is as follows: a low-cost CTP battery module rapid positioning tooling equipment for encapsulating battery blocks into a packaging box, including an auxiliary positioning component. The auxiliary positioning component includes a positioning frame set on the packaging box, brackets set at both ends of the positioning frame, a side platform set at the end of the bracket away from the positioning frame, two sliding bottom rods, two sliding top rods, and a control rod set between the two side platforms, a movable bottom strip set between the two sliding bottom rods, a sliding seat set outside the two sliding top rods and the control rod, a movable top strip set between the three sliding seats, an installation groove and a connecting air passage opened at the bottom of the movable top strip, a cover set at the opening of the connecting air passage, and an air pipe set outside the movable top strip for connecting the connecting air passage inside the adjacent movable top strip.

[0009] The sliding bottom rod and the movable bottom strip are both located below the positioning frame, while the sliding top rod, control rod, and movable top strip are located above the positioning frame. Symmetrical sliding grooves are provided at both ends of the outer side of the control rod. The number of sliding grooves is the same as that of the movable top strip. The sliding grooves are designed in a spiral shape, and all sliding grooves have the same number of spiral turns, the same starting and ending angles, and the pitch gradually increases from both ends of the sliding top rod towards the middle. A slider extending into the sliding groove is provided at the connection between the sliding seat and the control rod. The number of movable top strips is the same as that of the movable bottom strip. An adsorption assembly is provided in the mounting groove, and the air pipe is connected to the adsorption assembly through the mounting groove and the connecting air passage.

[0010] Furthermore, the air tube is spirally arranged and wrapped around the outside of the sliding top rod.

[0011] Furthermore, both the upper and lower ends of the side platform are provided with storage spaces to accommodate the movable bottom strip and the movable top strip.

[0012] Furthermore, the adsorption assembly includes a movable block disposed in the mounting groove, an inner air passage opened in the movable block, mounting holes arranged in a linear array at the bottom of the movable block, a connector disposed inside the mounting holes, an adsorption pad disposed at the bottom of the connector, and a docking hole opened between the connecting air passage and the inner air passage.

[0013] The mounting hole is connected to the internal air passage, and the docking hole is divided into two sections, one of which is located on the movable block and the other of which is located on the movable top bar.

[0014] Furthermore, the outer side of the adsorption pad is provided with a "V" shaped recess.

[0015] Furthermore, the top of the adsorption assembly is provided with a control assembly for controlling the movement of the movable block, and the adsorption assembly also includes a connecting tube disposed at the end of the docking hole near the movable block, a reset spring disposed on the outside of the connecting tube, and a thin film disposed inside the connecting tube.

[0016] The reset spring extends into the inner air passage and is supported between the connecting tube and the inner wall of the docking hole. The length of the connecting tube is not less than the length of the docking hole.

[0017] Furthermore, a buffer groove is provided at one end of the sliding groove near the center of the control rod.

[0018] Furthermore, the control component includes an L-shaped hole formed between the top wall of the mounting groove and the outer wall of the sliding seat, a pressure strip disposed in the vertical section of the L-shaped hole, a push block disposed in the horizontal section of the L-shaped hole, and a vertical plate disposed at the end of the push block away from the pressure strip.

[0019] The pressure strip and push block are fitted together at the bend of the L-shaped hole. The fitting area of ​​the pressure strip and push block is provided with a corresponding inclined surface. The upright plate is sleeved on the outside of the movable top strip. The connection between the upright plate and the control rod is provided with a slider that extends into the sliding groove.

[0020] Furthermore, the bottom of the upright plate is provided with a mating strip that fits against the bottom of the movable top strip.

[0021] Furthermore, the top of the packaging box is provided with bolt holes and guide holes, and the bottom of the positioning frame is provided with guide rods.

[0022] The beneficial effects of this invention are:

[0023] 1. By setting up an auxiliary positioning component, before installing the battery blocks into the packaging box, the battery blocks are first stacked into the auxiliary positioning component one by one. If placement errors occur during this process, adjustments can be made at will. Then, the control lever controls the moving top bar to gradually unfold, so that the moving top bar is distributed above the neatly stacked battery blocks. Finally, the positioning frame is connected to the packaging box, so that the battery blocks in the positioning frame slide into the packaging box. During this process, all battery blocks simultaneously come into contact with the adhesive on the bottom wall of the packaging box, so that the adhesive layer is evenly stressed and there is no problem of premature curing, ensuring the bonding quality. Relying on the pre-positioning of the tooling avoids assembly deviations, eliminates the need for secondary adjustments, significantly reduces the risk of module damage, simplifies the process, improves assembly efficiency, and the tooling structure is simple, low-cost, and suitable for mass production.

[0024] 2. By spiraling the air tube and wrapping it around the outside of the sliding top rod, with the two ends of the air tube connected to two adjacent moving top bars, the air tube slides outside the sliding top rod during the repeated opening and closing of the moving top bars. At the same time, it is regularly stretched or compressed along the axis of the sliding top rod, avoiding chaotic entanglement during high-frequency repetitive work.

[0025] 3. By setting a connecting pipe, when the control component controls the movable block to press down, the two docking holes are connected. Then, the connecting pipe is affected by the airflow and inserted into the sliding top rod on the side of the connecting airway, completing the connection between the connecting airway and the inner airway. This connection method has stronger sealing and ensures stable pressure when adsorbing the battery block. At the same time, the connecting pipe locks the movable block to the inner wall of the mounting groove, so that the movable block has a better load-bearing effect when the adsorption pad suspends the battery block.

[0026] 4. By setting control components, the adsorption pad should not come into contact with the battery block during the unfolding or closing of the moving top bar. This ensures the stable and smooth operation of the moving top bar and also prevents the surface of the battery block from being scratched. After the moving top bar moves above the designated battery block, the upright plate presses down the movable block through the push block and pressure bar, so that the adsorption pad comes into contact with the battery block. This ensures the tightness of the contact between the adsorption pad and the battery block and ensures the adsorption effect. Attached Figure Description

The auxiliary positioning component 3 includes a positioning frame 31 set on the encapsulation box 2, brackets 32 set at both ends of the positioning frame 31, a side platform 33 set at the end of the bracket 32 ​​away from the positioning frame 31, two sliding bottom rods 34, two sliding top rods 36, and a control rod 37 set between the two side platforms 33, a movable bottom strip 35 set between the two sliding bottom rods 34, a sliding seat 38 set outside the two sliding top rods 36 and the control rod 37, a movable top strip 39 set between the three sliding seats 38, a mounting groove 310 and a connecting air passage 311 opened at the bottom of the movable top strip 39, a cover 312 set at the opening of the connecting air passage 311, and an air pipe 313 set outside the movable top strip 39 for connecting the connecting air passage 311 inside the adjacent movable top strip 39.

[0047] Specifically, the bottom wall of the packaging box 2 is coated with adhesive, the positioning frame 31 has an embedded elastic rubber pad, the projection of the inner contour of the positioning frame 31 overlaps with the inner contour of the packaging box 2, the bracket 32 ​​is fixed to the side platform 33 by bolts, the bracket 32 ​​is welded to the positioning frame 31, the top of the bracket 32 ​​is provided with a hanging lug for connecting the suspension equipment, the upper and lower ends of the side platform 33 are provided with storage spaces 331 for accommodating the movable bottom strip 35 and the movable top strip 39, the sliding bottom rod 34 and the movable bottom strip 35 are both located below the positioning frame 31, the movable bottom strip 35 is slidably connected to one of the sliding bottom rods 34, the other sliding bottom rod 34 is provided with a spiral groove similar to the sliding groove 371 on the outside, used to control the movement of the movable bottom strip 35, the sliding top rod 36, the control rod 37 and the movable top strip 39 are located above the positioning frame 31, the sliding seat 38 is slidably sleeved on the outside of the sliding top rod 36 and the control rod 37, the control rod 37 is rotatably connected to the side platform 33, and controls the movement of the sliding bottom rod 35. The rod 37 is connected to the drive device. Symmetrical sliding grooves 371 are provided at both ends of the outer side of the control rod 37 to control the movement of the moving top bar 39. The number of sliding grooves 371 is the same as that of the moving top bar 39. The sliding grooves 371 are designed in a spiral shape, and all sliding grooves 371 have the same number of spiral turns, the same starting and ending angles, and the pitch gradually increases from both ends of the sliding top rod 36 towards the middle. A slider extending into the sliding groove 371 is provided at the connection between the sliding seat 38 and the control rod 37. The moving top bar 39 is fixedly connected to the sliding seat 38. The number of moving top bars 39 is the same as that of the moving bottom bar 35. An adsorption component 4 is provided in the mounting groove 310. The connecting air passage 311 is located on the side of the mounting groove 310. The cover 312 is snapped into the opening of the connecting air passage 311 and closes the connecting air passage 311. The air pipe 313 is connected to the adsorption component 4 through the mounting groove 310 and the connecting air passage 311. The air pipe 313 located at the leftmost or rightmost position is connected to the air pump.

[0048] By setting up the auxiliary positioning component 3, before installing the battery block 1 into the packaging box 2, the battery block 1 is first placed into the auxiliary positioning component 3 one by one. If there is a placement error during this process, it can be adjusted at will. Then, the control rod 37 controls the moving top bar 39 to gradually unfold, so that the moving top bar 39 is distributed above the neatly stacked battery block 1. Finally, the positioning frame 31 is docked with the packaging box 2, so that the battery block 1 in the positioning frame 31 slides into the packaging box 2. During this process, all battery blocks 1 are in contact with the adhesive on the bottom wall of the packaging box 2 at the same time, so that the adhesive layer is evenly stressed and there is no problem of premature curing, ensuring the bonding quality. By relying on the pre-positioning of the tooling, assembly deviations are avoided, no secondary adjustments are required, the risk of module damage is greatly reduced, the process is simplified, the assembly efficiency is improved, and the tooling structure is simple and low-cost, making it suitable for mass production.

[0049] Specifically, the air tube 313 is spirally arranged and wrapped around the outside of the sliding top rod 36. The two ends of the air tube 313 are connected to two adjacent movable top bars 39. In this way, as the movable top bars 39 repeatedly open and close, the air tube 313 slides outside the sliding top rod 36 and is stretched or compressed regularly along the axis of the sliding top rod 36, so as to avoid the situation of chaotic entanglement during high-frequency repetitive work.

[0050] The adsorption assembly 4 includes a movable block 41 disposed in the mounting groove 310, an inner air passage 42 opened in the movable block 41, mounting holes 43 arranged in a linear array at the bottom of the movable block 41, a connector 44 disposed inside the mounting holes 43, an adsorption pad 45 disposed at the bottom of the connector 44, and a docking hole 46 opened between the connecting air passage 311 and the inner air passage 42.

[0051] Specifically, the movable block 41 is slidably installed in the mounting groove 310, the mounting hole 43 is connected to the inner air passage 42, the connector 44 is fixed in the mounting hole 43 by threads, the adsorption pad 45 is sleeved on the bottom of the connector 44 and fixed with glue, the outer side of the adsorption pad 45 is provided with a "V" shaped recess to give it a certain compressibility, and the docking hole 46 is divided into two sections, one of which is located on the movable block 41 and the other of which is located on the movable top bar 39.

[0052] By setting the adsorption component 4, when the adsorption pad 45 comes into contact with the battery block 1, the air tube 313 creates a negative pressure space in the inner airway 42, and then the adsorption pad 45 adsorbs the battery block 1. In this way, after the moving bottom strip 35 closes into the storage space 331, the battery block 1 can still be placed in the positioning frame 31, which makes it convenient to adjust the position of the positioning frame 31 before placing the battery block 1.

[0053] The top of the adsorption component 4 is provided with a control component 5 for controlling the movement of the movable block 41. The adsorption component 4 also includes a connecting tube 47 disposed at one end of the docking hole 46 near the movable block 41, a reset spring 48 disposed on the outside of the connecting tube 47, and a film 49 disposed inside the connecting tube 47.

[0054] Specifically, the connecting tube 47 is slidably installed in the docking hole 46, the return spring 48 extends into the inner air passage 42, and the return spring 48 is supported between the connecting tube 47 and the inner wall of the docking hole 46. The length of the connecting tube 47 is not less than the length of the docking hole 46. The return spring 48 is ultrasonically welded to the connecting tube 47. An elastic hole is opened at the center of the diaphragm 49. When squeezed by the airflow, the elastic hole will continuously expand, so that the connecting tube 47 can move under the influence of the airflow.

[0055] By setting the connecting pipe 47, when the control component 5 controls the movable block 41 to press down, the two docking holes 46 are connected. Then, the connecting pipe 47 is affected by the airflow and inserted into the sliding top rod 36 on the side of the connecting airway 311 to complete the connection between the connecting airway 311 and the inner airway 42. This connection method has stronger sealing and ensures stable pressure when adsorbing the battery block 1. At the same time, the connecting pipe 47 locks the movable block 41 to the inner wall of the mounting groove 310. When the adsorption pad 45 suspends the battery block 1, the movable block 41 has a better load-bearing effect.

[0056] Specifically, a buffer groove 372 is provided at one end of the sliding groove 371 near the center of the control rod 37. The buffer groove 372 is provided around the circumference of the control rod 37, and the angle difference between the beginning and end does not exceed thirty degrees.

[0057] The control component 5 includes an L-shaped hole 51 formed between the top wall of the mounting groove 310 and the outer wall of the sliding seat 38, a pressure strip 52 disposed in the vertical section of the L-shaped hole 51, a push block 53 disposed in the horizontal section of the L-shaped hole 51, and a vertical plate 54 disposed at the end of the push block 53 away from the pressure strip 52.

[0058] Specifically, the pressure strip 52 is slidably installed in the L-shaped hole 51, and the bottom end of the L-shaped hole 51 is fixedly connected to the movable block 41. The pressure strip 52 and the push block 53 are attached at the bend of the L-shaped hole 51. The attachment point of the pressure strip 52 and the push block 53 is provided with a corresponding inclined surface. The upright plate 54 is fixedly connected to the push block 53. The upright plate 54 is sleeved on the outside of the movable top strip 39. The connection point between the upright plate 54 and the control rod 37 is provided with a slider extending into the sliding groove 371.

[0059] By setting the control component 5, the adsorption pad 45 should not come into contact with the battery block 1 during the unfolding or closing of the moving top bar 39. This ensures the stable and smooth operation of the moving top bar 39 and also prevents the surface of the battery block 1 from being scratched. After the moving top bar 39 moves above the designated battery block 1, the upright plate 54 presses down the movable block 41 through the push block 53 and the pressure bar 52, so that the adsorption pad 45 comes into contact with the battery block 1. This ensures the tightness of the contact between the adsorption pad 45 and the battery block 1 and ensures the adsorption effect.

[0060] Specifically, the bottom of the upright plate 54 is provided with a mating strip 55 that fits into the bottom of the movable top strip 39. When the control rod 37 pushes the upright plate 54, the mating strip 55 supports both ends of the upright plate 54, restricts its circumferential deflection, and ensures stable operation of the equipment.

[0061] Specifically, the top of the packaging box 2 is provided with bolt holes 21 and guide holes 22. The upper opening of the guide hole 22 is provided with an outwardly flared chamfer. The bottom of the positioning frame 31 is threadedly connected to a guide rod 23. During the docking process between the positioning frame 31 and the packaging box 2, the guide rod 23 is first inserted into the guide hole 22, thus ensuring the positioning and installation accuracy of the positioning frame 31 and the packaging box 2.

[0062] During use, the sliding bottom rod 34 is used to unfold the movable bottom strip 35, allowing it to leave the storage space 331 and be evenly laid below the positioning frame 31. Then, battery blocks 1 are placed one by one into the positioning frame 31, with the movable bottom strip 35 supporting them. After the battery blocks 1 are laid out, the drive control rod 37 is rotated. The control rod 37 controls the movable top strip 39 to unfold via the sliding groove 371 on its surface. The upright plate 54 moves synchronously with the movable top strip 39. After moving to the end of one end of the sliding groove 371, the moving top bar 39 is also located above the corresponding row of battery blocks 1. The control rod 37 continues to rotate, and the slider corresponding to the sliding seat 38 enters the buffer groove 372. The upright plate 54 continues to move under the influence of the sliding groove 371, so that the upright plate 54 is close to the sliding seat 38. The upright plate 54 pushes the pressure bar 52 through the push block 53, and the L-shaped hole 51 presses down the movable block 41, so that the adsorption pad 45 is pressed against the top of the battery block 1, and the two docking holes 46 are also docked.

[0063] The air pump is started, and the air pump creates negative pressure in the connecting air passage 311 at the bottom of all the movable top strips 39 through the air pipe 313. The negative pressure draws the return spring 48 into the docking hole 46 near the connecting air passage 311, connecting the inner air passage 42 and the connecting air passage 311. The negative pressure affects the inner air passage 42, and the adsorption pad 45 begins to generate adsorption force on the battery block 1. Then the movable bottom strip 35 is retracted into the storage space 331, so that the bottom of the positioning frame 31 is completely exposed. Finally, the positioning frame 31 is moved above the encapsulation box 2, the air pump balances the internal and external air pressure, the battery block 1 loses its adsorption force and slides into the encapsulation box 2.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
