Description

Technical Field

[0001] This invention relates to the field of new energy battery assembly technology, specifically to an integrated assembly equipment for new energy power battery PACK modules. Background Technology

[0002] The power battery pack is a core component of the power battery system of new energy vehicles. As the basic unit of the pack, the assembly precision of the module directly affects the performance, safety and production efficiency of the entire battery system.

[0003] In actual production, misalignment often occurs during module assembly. Specifically, this manifests as misalignment between modules, between modules and the PACK housing, and between terminals and busbars. Minor issues may require manual rework and adjustment, reducing production cycle time, while major issues may lead to loose terminal connections, uneven stress on modules, and serious safety hazards such as increased overheating, insulation failure, or even thermal runaway during subsequent use.

[0004] Some production line processes have design flaws that make it difficult to guarantee accuracy. The pressure distribution is uneven. Currently, manual pre-positioning is used followed by direct clamping without a secondary alignment and calibration process. When multiple modules are placed into the box in sequence, the deviations accumulate, eventually leading to overall alignment failure. During the welding process, the modules are subjected to uneven pressure and displacement occurs without prior positioning and locking.

[0005] Therefore, it is necessary to design an integrated assembly equipment for new energy power battery PACK modules. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0022] An integrated assembly equipment for new energy power battery PACK modules is disclosed. The assembly equipment is mainly used for assembling new energy power batteries, pre-installing and integrating new energy power battery PACK modules, and assembling new energy battery blocks into battery PACK modules. It belongs to the field of battery production and manufacturing. If the new energy batteries are automatically aligned and extruded, and the top cover and battery straps are assembled, then the assembly equipment belongs to the field of intelligent manufacturing equipment, which reduces manual operation costs and improves efficiency.

[0023] according to Figure 1 As shown, the integrated assembly equipment for the new energy power battery PACK module includes a base plate 1, which is used to support the relevant assembly mechanism and form the battery assembly area. Mounting plates 2 are fixedly installed at both ends of the base plate 1. Electric guide rails 21 are provided on the mounting plates 2 to drive the assembly mechanism to move horizontally. The electric guide rails 21 are existing technology and will not be described in detail here.

[0024] The assembly equipment consists of mounting plate 2 and base plate 1, forming the overall production area.

[0025] according to Figure 2As shown, a fixing plate 11 is fixedly provided on the base plate 1. The fixing plate 11 is fixed to the base plate 1 by a support column. There is a gap between the fixing plate 11 and the base plate 1. A pad rod 12 is fixedly installed on the fixing plate 11. A sliding movable support rod 15 is provided between adjacent pad rods 12. The pad rods 12 are used to support the battery block 6 to arrange and place the battery block 6 to be assembled. At this time, glue has been applied to both sides of the battery block 6.

[0026] The movable support rod 15 slides horizontally on the fixed plate 11, which can be used to extend the support length above the pad rod 12, making it easier to support and lift battery PACK modules of different lengths and sizes, improving the flexibility of equipment assembly, and enabling the assembly of a large number of battery blocks 6.

[0027] The main body of the battery PACK module consists of different numbers of battery blocks 6, which can be assembled into a single-row structure as needed (e.g., Figure 11 As shown), double-column structure (such as...) Figure 12 As shown in the figure, or a multi-column structure, and the end of the battery PACK module needs to be assembled with end cap 8. Sensors and other components are assembled on the end cap 8. Finally, at least one battery strap 7 is fitted on the outside of the battery PACK module and the end cap 8. In this embodiment, two battery straps 7 are provided to bind and fix the upper and lower sides of the battery, keep the battery blocks 6 tightly bonded, improve the structural firmness of the battery blocks 6, and improve the connection firmness of the end cap 8, effectively avoiding problems such as detachment and loosening.

[0028] according to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an mounting block 22 is provided on the electric guide rail 21. The mounting block 22 slides under the drive of the electric guide rail 21, so that it moves closer to or away from the battery to be assembled, thus moving the assembly mechanism.

[0029] Connecting arms 23 are fixedly installed on both sides of the mounting block 22. A push plate 24 is fixed between the connecting arms 23 by bolts. Several push arms 28 are provided at the front end of the push plate 24. A pressure plate 29 is fixedly installed at the front end of the push arm 28. The pressure plate 29 is attached to the front side of the end cover 8 or the end battery block 6 to move and compact the battery block 6 or the end cover 8.

[0030] A sensor 241 is fixedly installed below the push plate 24. The sensor 241 is used to monitor the products (such as end cap 8 or battery block 6) on the front side of the push plate 24 to measure the spacing, so as to control the movement and displacement of the electric guide rail 21. The electric guide rail 21 can be driven manually or controlled by a computer. The monitoring data of the sensor 241 is transmitted to the computer.

[0031] In this embodiment, the push arm 28 is made of a high-strength rod, or it can be replaced by a servo cylinder.

[0032] Two connecting seats 4 are fixedly provided below the push plate 24. A protrusion 18 is provided on one side of the connecting seat 4. A horizontally arranged round rod 19 is installed on the protrusion 18. After the round rod 19 passes through a connecting seat 4, a fine adjustment spring 10 is fitted at its end. One end of the fine adjustment spring 10 is attached to the other side of the connecting seat 4.

[0033] A synchronization plate 17 is connected to the lower part of the protrusion 18. Several locking rods 16 are fixed on the front side of the synchronization plate 17. The locking rods 16 are locked to the end of the movable support rod 15 and connected by bolts.

[0034] In this embodiment, after the protrusion 18 is attached to the side of the connecting seat 4 and moves towards the battery block 6, the fine-tuning spring 10 is in the normal state, squeezing the battery block 6 to complete the attachment assembly. Conversely, since the battery block 6 is pressed on the moving support rod 15, the protrusion 18 and the moving support rod 15 are subjected to the pressure of the battery block 6. If the connecting seat 4 moves away from the battery block 6, the protrusion 18 will disengage from the side of the connecting seat 4 when the connecting seat 4 moves. At this time, the fine-tuning spring 10 is in the compressed state, and the pressure plate 29 disengages from the battery block 6, leaving a gap for the insertion of the end cap 8.

[0035] according to Figure 8 As shown, a side clamping rod 31 is provided on the outer side of the fixing plate 11. The side clamping rod 31 is located on both sides of the fixing plate 11 and pushes the outer side of the battery block 6 to align the battery block 6. If it is a double row of battery blocks 6, it will align the double row of battery blocks 6. A guide block 33 is provided in the gap between the fixing plate 11 and the bottom plate 1. A guide rod 32 is slidably provided on the guide block 33. One end of the guide rod 32 is fixedly connected to the side clamping rod 31, so that the side clamping rod 31 is guided and slid under the cooperation of the guide rod 32 and the guide block 33, so that the two side clamping rods 31 move towards each other or in opposite directions.

[0036] A motor 34 is fixedly installed in the gap between the fixed plate 11 and the base plate 1. The output end of the motor 34 is connected to a bidirectional lead screw 36. A moving block 35 is connected to the bottom of the side clamping rod 31. The moving block 35 is threadedly connected to the bidirectional lead screw 36. The motor 34 controls the bidirectional lead screw 36 to rotate, which can drive the two side clamping rods 31 to move.

[0037] When using: In the initial state, the movable support rod 15 and the pad rod 12 are placed side by side, and the battery strap 7 is placed at the end of the movable support rod 15. The battery strap 7 is located above the clamp rod 16 and will not interfere with the placement and arrangement of the battery block 6. After the battery block 6 is coated with glue, it is placed above the movable support rod 15 and the pad rod 12. Then, when the two side clamp rods 31 move towards each other, they push and align the two sides of the battery block 6 arranged on the pad rod 12, so that the gap between adjacent battery blocks 6 is reduced, ensuring that the adjacent battery blocks 6 can be tightly bonded after the glue is applied, avoiding uneven bonding and excessive local gaps, and improving the structural stability after bonding.

[0038] After the sides of the battery blocks 6 are aligned, the push plate 24, driven by the electric guide rail 21, drives the pressure plate 29 to push the battery blocks 6 at the ends, applying pressure to the ends of all the arranged battery blocks 6, so that the glue on the surface of the adjacent battery blocks 6 is evenly spread, further ensuring the tightness of the adhesion. After applying pressure for a certain period of time and waiting for the glue to initially cure, the push plate 24 returns to its original position away from the battery blocks 6. During this process, the connecting seat 4 moves backward away from the battery blocks 6 along with the push plate 24. The protrusion 18 is temporarily not under pressure from the moving support rod 15 and the battery blocks 6, so that the fine adjustment spring 10 is squeezed and in a compressed state. When the fine adjustment spring 10 can no longer pull the protrusion 18, the backward movement of the push plate 24 stops. At this time, the push plate 24 and the pressure plate 29 are completely separated from the end face of the outermost battery block 6, leaving space for the installation of the end cover 8.

[0039] Next, the end cap 8, coated with glue, is manually placed at the aligned end of the battery block 6. The electric guide rail 21 drives the push plate 24 forward again, and the pressure plate 29 pushes the end cap 8 to fit against the end of the battery block 6, completing the pre-installation positioning of the end cap 8. Then, the bidirectional lead screw 36 is controlled to rotate, and the battery strap 7, which is clamped on the outside of the moving support rod 15 and located on the clamp rod 16, is moved upward and successfully placed on the lower side of the battery PACK module. Then, another battery strap 7 is taken and placed on the upper side of the battery PACK module from top to bottom. The fitting is manually observed to be in place. After the binding and fixing are completed, the clamping of the equipment is released, and each component is reset. The assembled new energy power battery PACK module can then be taken out, realizing the integrated power battery PACK module assembly. Example

[0040] Based on Example 1, according to Figure 2 As shown, a through groove 13 is provided in the middle of the fixed plate 11, and a vertically sliding connecting plate 14 is provided in the through groove 13. A connecting seat 4 is fixed on the connecting plate 14, and an elastic component is provided on the connecting seat 4.

[0041] The elastic assembly includes two inner expansion plates 41 slidably mounted on the connecting seat 4. The two inner expansion plates 41 move towards each other. A column 42 is fixedly mounted on each inner expansion plate 41. A return spring 5 is connected between the columns 42 on the two inner expansion plates 41. A push rod 43 is also provided on the outer side of the inner expansion plates 41. The connecting seat 4 divides the area above the fixed plate 11 into two assembly areas for... Figure 11 Assemble the single-row battery pack shown.

[0042] A cylinder 25 is fixedly mounted on the top of the push plate 24. A vertical guide rail 26 is fixedly mounted below the cylinder 25 and on the front side of the push plate 24. A pressure rod 27 is slidably mounted on the vertical guide rail 26. Figure 7 As shown, the lower end of the pressure bar 27 is provided with an inclined surface structure 271.

[0043] When using: After the battery block 6 is coated with adhesive, it is placed above the moving support rod 15 and the pad rod 12, and is located between the push rod 43 and the side clamping rod 31. When it is necessary to align the side of the battery block 6, the cylinder 25 pushes down the pressure rod 27, so that the pressure rod 27 is inserted between the two inner expansion plates 41. The inclined structure 271 pushes the inner expansion plates 41 outward, so that the push rod 43 moves outward, pushing and aligning the battery block 6. The remaining assembly operations are the same as those in the detailed figure of Embodiment 1.

[0044] If the pressure rod 27 is withdrawn between the two inner expansion plates 41, the deformation is restored by the return spring 5, the two inner expansion plates 41 are reset, and the clamping of the battery block 6 is released.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
