Description

Technical Field

[0001] This invention relates to the field of new energy module production technology, specifically to a pressurized static device for new energy modules. Background Technology

[0002] During the production process of new energy modules, the battery pack needs to be placed into the battery casing. The inside of the battery casing is pre-laid with a layer of gel (for later cooling). In existing equipment, the efficiency of letting the battery pack stand still after being placed in the casing is low, and the pressure on different parts will be different, resulting in uneven spreading of the gel, which affects the overall quality of the new energy module. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a pressurized static setting device for new energy modules, which can effectively solve the problems of poor efficiency and quality in the static setting of new energy modules in the existing technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention provides a pressurized static device for a new energy module, comprising a device frame and further comprising:

[0006] A conveying mechanism, including a conveyor located in a device frame, on which a module assembly is placed;

[0007] The positioning mechanism includes a battery cell pad movably mounted on a conveyor, wherein the battery cell pad has an adsorption cavity, and when the battery cell pad is squeezed down by the mold assembly, it adheres to the bottom wall of the mold assembly through the adsorption cavity.

[0008] The static pressure mechanism includes a static pressure frame slidably mounted on a device frame, on which multiple pressure plates are slidably mounted. The static pressure frame is equipped with an adjusting element for adjusting the spacing between adjacent pressure plates.

[0009] Furthermore, the conveying component includes a PACK vehicle, the top of which is provided with a mounting plate. Battery cell pads are mounted on two symmetrical surfaces of the mounting plate, and positioning plates are mounted on the other two symmetrical surfaces of the mounting plate. A disassembly assembly is installed between the positioning plate and the mounting plate.

[0010] Furthermore, the mounting plate has multiple mounting holes, the battery cell pads are installed in the mounting holes, and the multiple battery cell pads are distributed at equal distances on the mounting plate.

[0011] Furthermore, a second piston disc is movably disposed in the adsorption cavity of the battery cell pad, a piston tube is fixedly installed on the bottom wall of the mounting hole, a first piston plate is movably installed in the piston tube, a connecting tube is fixedly connected to the top wall of the first piston plate, and the top end of the connecting tube movably passes through the top end of the piston tube and extends into the adsorption cavity. A connecting hole is opened on the side wall of the connecting tube at one end of the piston tube.

[0012] Furthermore, a sliding groove is provided on the side wall of the mounting hole, and a slider adapted to the sliding groove is installed on the side wall of the battery cell pad. A return spring is connected between the slider and the sliding groove.

[0013] Furthermore, a sealing ring is provided at the top of the mounting hole.

[0014] Furthermore, the module assembly includes a battery pack housing placed on top of the cell pad, and multiple battery packs are placed inside the battery pack housing.

[0015] Furthermore, the static pressure mechanism also includes two gantry frames fixedly installed on the equipment frame. Each of the two gantry frames is fixedly installed with a sliding frame. A mounting frame is slidably installed between the two sliding frames. Multiple static pressure frames are slidably installed on the mounting frame. Multiple pressure plates are slidably installed at the bottom ends of the multiple static pressure frames one-to-one. Each static pressure frame is provided with a first electric push rod for driving the pressure plate to rise and fall. The sliding frame is provided with a first driving component for driving the mounting frame to slide. The mounting frame is provided with a second driving component for driving the static pressure frame.

[0016] Furthermore, the equipment frame is provided with a guide frame, a guide block is slidably installed in the guide frame, a movable block is slidably installed on the guide block, and a clamping member is provided on the movable block.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] The present invention will be further described below with reference to embodiments.

[0029] Example 1:

[0030] refer to Figure 3 A new energy module pressurization and static placement device includes an equipment frame 1 and a conveying mechanism, including a conveying component located in the equipment frame 1. A module assembly is placed on the conveying component. The module assembly includes a battery pack shell 11 placed on top of a cell pad 17. Multiple battery packs 12 are placed in the battery pack shell 11. The conveying component includes a PACK cart 13. A mounting plate 14 is provided on the top of the PACK cart 13. Cell pads 16 are installed on two symmetrical surfaces of the mounting plate 14. Positioning plates 15 are installed on the other two symmetrical surfaces of the mounting plate 14. A disassembly and assembly assembly is installed between the positioning plate 15 and the mounting plate 14. Multiple mounting holes are opened on the mounting plate 14. Cell pads 17 are installed in the mounting holes, and the multiple cell pads 17 are evenly distributed on the mounting plate 14.

[0031] like Figure 3 As shown, the conveyor uses a PACK cart 13 with automatic cruise control (existing technology will not be elaborated further). A mounting plate 14 is installed on the top of the PACK cart 13, and a positioning plate 15 on the side of the mounting plate 14 is used to adapt to the battery pack casing 11. A disassembly assembly is provided between the positioning plate 15 and the mounting plate 14, and different positioning plates 15 can be installed to adapt to different models of battery pack casings 11. The PACK cart 13 conveys the battery modules (new energy modules) to be statically pressed to the bottom of the subsequent static pressing mechanism to assist in static pressing, which not only improves the degree of automation, but also improves the efficiency and quality of static pressing.

[0032] refer to Figure 4 and Figure 5 The equipment is equipped with a positioning mechanism, including a battery cell pad 17 movably mounted on the conveyor. The battery cell pad 17 has an adsorption cavity. When the battery cell pad 17 is squeezed down by the mold assembly, it adheres to the bottom wall of the mold assembly through the adsorption cavity. A second piston disc 25 is movably mounted in the adsorption cavity of the battery cell pad 17. A piston tube 21 is fixedly mounted on the bottom wall of the mounting hole. A first piston plate 22 is movably mounted in the piston tube 21. A connecting tube 23 is fixedly connected to the top wall of the first piston plate 22. The top end of the connecting tube 23 movably passes through the top end of the piston tube 21 and extends into the adsorption cavity. A connecting hole 24 is opened on the side wall of the connecting tube 23 at one end of the piston tube 21. A sliding groove 19 is opened on the side wall of the mounting hole. A slider 18 that matches the sliding groove 19 is installed on the side wall of the battery cell pad 17. A return spring (not shown in the figure) is connected between the slider 18 and the sliding groove 19. A sealing ring 20 is provided at the top end of the mounting hole.

[0033] To improve the stability of the battery module on top of PACK 13, and its stability under subsequent static pressure, such as Figure 5 As shown, a cell pad 17 is provided on the top of the mounting plate 14. When the battery module is placed on top of the cell module 17, its gravity will squeeze the cell pad 17 downward, thereby causing the connecting tube 23 and the first piston disc 25 to move downward. This increases the space at the top of the piston tube 21, allowing air to be drawn from the bottom of the adsorption chamber through the connecting hole 24 and the connecting tube 23. This increases the space above the second piston disc 25 and reduces the internal air pressure, thus allowing the sealing ring 20 to tightly adsorb the bottom wall of the battery module. This improves the stability of transportation and prevents the battery module from shifting during static pressure.

[0034] Example 2:

[0035] refer to Figure 1 To ensure the gel in the module is spread more evenly and that the tops of the modules are at the same level, a static pressure mechanism is installed on the equipment frame 1. This mechanism includes a static pressure frame 5 slidably mounted on the equipment frame 1, with multiple pressure plates slidably mounted on the static pressure frame 5. The static pressure frame 5 is equipped with an adjusting component to adjust the spacing between adjacent pressure plates. The static pressure mechanism also includes two gantry frames 2 fixedly mounted on the equipment frame 1, each with a sliding frame 3 fixedly mounted on it. A mounting frame 4 is slidably mounted between the two sliding frames 3, with multiple static pressure frames 5 slidably mounted on the mounting frame 4. Multiple pressure plates 7 are slidably mounted one-to-one on the bottom of the multiple static pressure frames 5. Each static pressure frame 5 is equipped with a first electric push rod 6 for driving the pressure plate 7 to rise and fall. The sliding frame 3 is equipped with a first electric push rod 6 for driving the mounting frame 4 to slide. The drive component 8 and the mounting bracket 4 are equipped with a second drive component 9 for driving the static pressure frame 5. The equipment frame 1 is provided with a guide frame 10. A guide block 26 is slidably installed in the guide frame 10. A movable block 27 is slidably installed on the guide block 26. A clamping component is provided on the movable block 27. When the battery cell pad 16 slides into the guide frame 10, it is clamped by the clamping component. When the movable block 27 moves upward, the clamping force is increased. The clamping component includes a second clamping plate 28 slidably installed on one side of the movable block 27. A first clamping plate is fixedly installed on one side of the movable block 27. The battery cell pad 16 is located between the first clamping plate and the second clamping plate 28. A locking rod 29 is movably inserted into the top wall of the movable block 27. The bottom end of the locking rod 29 is fixedly connected to the second clamping plate 28. The top wall of the guide frame 10 is provided with multiple locking teeth that are adapted to the locking rod 29.

[0036] PACK 13 moves the module into device frame 1 (e.g., ... Figure 1As shown, the module is transported directly below the static pressure mechanism. Multiple pressure plates 7 are driven downwards by the first electric push rod 6, compressing the module below and ensuring the top of the battery pack inside the module is at the same level. This not only facilitates subsequent cover installation but also ensures cooling efficiency and quality during later module use. The static pressure frame 5 is slidably mounted on the mounting frame 4. The position of the static pressure frame 5 can be adjusted via the second drive component 9, specifically in the Y-direction. The mounting frame 4 itself can be adjusted via the first drive component 8, in the X-direction. Furthermore, the spacing between adjacent static pressure frames 5 can also be adjusted via the drive component to accommodate different module models.

[0037] A guide frame 10 is set on the equipment frame 1. When the PACK cart 13 moves, the side cell pad 16 slides into the guide frame 10, and the pressing movable block 27 slides along the guide frame 10. On the one hand, it assists the PACK cart 13 in guiding, and on the other hand, it can prevent the upper module from shifting.

[0038] After moving to the target area, a third driving component is installed in the equipment frame 1 to push the mounting plate 14 upwards a certain distance. This prevents subsequent static pressure from being transferred to the PACK cart 13, protecting the safety of the PACK cart 13. When the mounting plate 14 moves upwards, the side cell pad 16 also moves upwards, as... Figure 4 As shown, the upward movement of the cell pad 16 causes the movable block 27 to move upward, and the top of the locking rod 29 is inserted into the upper locking tooth for positioning. The locking rod 29 will move downward a certain distance, causing the second clamping plate 28 to move downward to cooperate with the first clamping plate to clamp the cell pad 16 and complete the positioning, preventing any deviation.

[0039] In addition to the above, the device also has the following functions:

[0040] 1. The equipment has overvoltage protection and mechanical limit protection capabilities, and also has an alarm function.

[0041] 2. Pressure of a single double-row module ≥ 500 kgf.

[0042] 3. The contact surface with the battery cell terminal should be made of insulating material to avoid the risk of short circuit; and the surface of the terminal should not be damaged.

[0043] 4. Real-time monitoring of process pressure, with the ability to upload data to the MES (Manufacturing Execution System).

[0044] 5. The three-axis mechanism has a stable and robust structure.

[0045] The accuracy of the equipment's specifications is as follows:

[0046] 1. Flatness of the contact plate of the battery cell electrode: ≤0.2mm.

[0047] 2. Adhesive bonding area: ≥95%.

[0048] 3. Pressure ≥ 500 kgf

[0049] 4. Adhesive application time: Adhesive application time is 40S±20S. If the AGV (PACK vehicle) does not move within the set time, the equipment will automatically alarm.

[0050] 5. Pressure accuracy ±0.5 kgf.

[0054] 3. It has overvoltage protection and limit protection.

[0056] 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 the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
