Description

Technical Field

[0001] This utility model relates to the technical field of battery box production equipment, and in particular to a water nozzle glue applicator for the lower box of a power battery. Background Technology

[0002] In today's era, the new energy vehicle industry is booming, becoming a key force in the global transportation sector's transformation towards sustainable development. Among its components, the new energy vehicle battery system is paramount, with its performance and safety being of utmost importance. The battery housing, as a crucial component housing and protecting the battery modules, occupies a central position within the entire battery system.

[0003] Thermal management is crucial during battery operation. A cooling system is indispensable to ensure the battery operates within a suitable temperature range, and the water nozzles on the battery casing are the key connection points for interaction between the cooling system and the battery casing. Coolant circulates between the battery casing and the cooling system through the water nozzles, facilitating heat transfer.

[0004] However, there are currently a series of problems that urgently need to be solved at the connection point between the water tap and the battery box.

[0005] From a vehicle operation perspective, new energy vehicles encounter a variety of complex road conditions while driving. Whether it's the severe bumps caused by driving on rough roads or the vibrations from frequent start-stop cycles, the battery pack will be subjected to varying degrees of external forces. These external forces acting on the battery pack can easily cause the connection between the water inlet and the battery pack to loosen. The tiny gaps created by this loosening become a potential threat to the normal operation of the battery system.

[0006] In terms of environmental factors, new energy vehicles face diverse environmental conditions during use. Temperature varies significantly across seasons and regions, and humidity differs greatly in different climates. Furthermore, vehicles come into contact with substantial amounts of dust and impurities during operation. Gaps created by loose connections between the water inlet and the battery pack allow these external factors to easily penetrate the battery compartment. Moisture entering through these gaps can corrode internal metal components and, when electrical components are involved, may cause short circuits, severely impacting the battery system's safety. Dust and impurities accumulate on the battery module surface, reducing heat dissipation efficiency. Since heat dissipation requires good heat conduction channels, the presence of impurities hinders heat transfer, thus affecting battery performance and lifespan.

[0007] In addition, moisture can easily accumulate at the connection between the water tap and the battery box, which can corrode the battery box and further reduce its lifespan.

[0008] Current sealing technologies at this connection point have significant shortcomings. Traditional sealing methods, such as simple rubber gasket seals, are prone to aging and deformation under complex vibrations and long-term use, leading to a decline in sealing effectiveness. Furthermore, for the unique connection structure between the water tap and the battery casing, rubber gaskets may not fully conform to the irregular connection surface, failing to effectively fill all gaps. Additionally, while some manual glue application methods can fill gaps to a certain extent, the limitations of manual operation make it difficult to ensure uniformity and accuracy. Excessive glue may overflow and contaminate other components inside the battery casing, while insufficient glue will not achieve a good seal. This exposes the battery system to the risk of unstable sealing, thereby affecting the stable operation of the battery and overall safety.

[0009] In summary, to ensure the stable and efficient operation of new energy vehicle battery systems and improve their safety and lifespan, there is an urgent need for a device that can accurately and efficiently apply adhesive to the connection points between the water nozzle and the battery housing.

Detailed Implementation

[0030] This utility model provides a water nozzle glue application device for the lower casing of a power battery. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0031] Please see Figures 1-4This utility model provides a water nozzle glue application device for the lower casing of a power battery, including a frame (not shown in the figure), a rotating mechanism 1 mounted on the frame, a positioning frame 2 connected to the output end of the rotating mechanism 1, a robotic arm 3 mounted on one side of the rotating mechanism 1, a glue application mechanism 4 fixedly connected to the robotic arm 3, a positioning mechanism 5 mounted on the positioning frame 2, and a pressing mechanism 6; the positioning mechanism 5 is used to determine the position of the lower casing 10 of the battery placed on the positioning frame 2; the pressing mechanism 6 is used to press the lower casing 10 of the battery; the rotating mechanism 1 is used to drive the positioning frame 2 to rotate horizontally at a set angle; the robotic arm 3 is used to drive the glue application mechanism 4 to apply glue to the gap between the lower casing 10 of the battery and the water nozzle 20. Figure 4 The P-marked point indicates the glue application location.

[0032] In practical applications, the frame is box-shaped, and the glue applicator for the lower housing of the power battery is located inside the box-shaped frame. An opening is provided at the front of the box-shaped frame, and the operator faces the opening to perform operations such as loading, unloading, and control. In this technical solution, the robotic arm 3 is described with its position at the rear.

[0033] In the initial state of this technical solution, the worker faces the glue application device and loads the lower battery casing 10 onto the positioning frame 2. The positioning mechanism 5 positions the lower battery casing 10 to ensure its correct loading position. Then, the pressing mechanism 6 operates, pressing the lower battery casing 10 onto the positioning frame 2 to prevent it from falling off. Next, the rotating mechanism 1 rotates the positioning frame 2 180° (specifically, the rotation angle and process of the rotating mechanism 1 vary depending on the positions of the positioning frame 2 and the robotic arm 3, therefore this invention does not limit this), causing the lower battery casing 10, originally in front, to rotate to the rear, i.e., facing the robotic arm 3. Subsequently, the robotic arm 3 moves the glue application mechanism 4 and applies glue to the gap between the lower battery casing 10 and the water nozzle 20. In this embodiment, the glue application mechanism 4 is a glue gun, using a two-component adhesive mixed in a specific ratio, which can cure at room temperature or under heating conditions.

[0034] In the aforementioned device, the positioning mechanism 5 accurately determines the position of the lower battery housing 10 placed on the positioning frame 2, effectively avoiding inaccurate glue application due to placement deviations of the lower battery housing 10. This ensures the precision of subsequent glue application operations and improves product quality consistency. The clamping mechanism 6 stably clamps the lower battery housing 10. During the glue application process, the lower battery housing 10 will not shift due to the movement of the robotic arm 3 or other external forces, creating a stable working environment for the glue application and reducing glue application errors caused by housing shaking. Through the synergistic effect of the aforementioned positioning, clamping, angle adjustment, and precise glue application functions, the glue application quality between the water nozzle 20 and the lower battery housing 10 is effectively guaranteed, improving the strength and sealing of the connection, reducing quality problems such as leakage caused by poor glue application, and enhancing the overall reliability of the product.

[0035] Please see Figures 1-4 In some embodiments, the positioning mechanism 5 includes multiple support seats 51 and anti-misalignment blocks 53 disposed on the side wall of the positioning frame 2; the outer side walls of the multiple support seats 51 are respectively used to abut against the inner side wall of the lower battery housing 10, and the outer side walls of two or more support seats 51 are also provided with positioning pins 52, the ends of which are used to insert into the positioning holes 301 of the brackets 30 corresponding to the lower battery housing 10; the multiple anti-misalignment blocks 53 are respectively used to limit the position of the lower battery housing 10 placed on the positioning frame 2. During loading, the water nozzle 20 is located above the lower battery housing 10, and the lower battery housing 10 is generally rectangular. In this embodiment, five anti-misalignment blocks 53 are set, two of which are located at the top and arranged left and right, two of which are located at the bottom and arranged left and right, and one of which is located at the bottom and is used to support the bottom of the lower battery housing 10. In this embodiment, four support bases 51 are provided, located at the four corners of the positioning frame 2. Positioning pins 52 are provided on the two support bases 51 on the right side, in conjunction with the position of the bracket 30 of the lower battery housing 10. Through the arrangement of multiple support bases 51 and anti-fooling blocks 53, the initial positioning of the lower battery housing 10 can be achieved, ensuring that the lower battery housing 10 is correctly positioned relative to the positioning frame 2.

[0036] Please see Figure 2In some embodiments, the clamping mechanism 6 includes a clamping cylinder 61 fixed to the positioning frame 2, a hinge seat 62 disposed on the cylinder body of the clamping cylinder 61, and a pressure rod 63 disposed on the output end of the clamping cylinder 61; the hinge seat 62 is connected to the middle part of the pressure rod 63; the end of the pressure rod 63 is used to abut against the outer side wall of the lower battery housing 10. After the lower battery housing 10 is placed in position, the output end of the clamping cylinder 61 extends, and the connecting end of the pressure rod 63 rotates around the hinge seat 62, so that the free end of the pressure rod 63 moves toward the lower battery housing 10 (rearward), thereby clamping the lower battery housing 10. Conversely, when the adhesive is applied and material needs to be unloaded, the output end of the clamping cylinder 61 retracts, so that the free end of the pressure rod 63 moves away from the lower battery housing 10 (forward), providing clearance space for the unloading of the lower battery housing 10.

[0037] Please see Figure 1 and Figure 3 In some embodiments, four clamping mechanisms 6 are provided, and the pressure rods 63 on the four clamping mechanisms 6 are respectively used to abut against the outer side of the corresponding bracket 30 on the lower battery housing 10. The number of clamping mechanisms 6 and the clamping positions of the pressure rods 63 are limited according to the shape of the lower battery housing 10 and the number of brackets 30 to ensure the clamping effect on the lower battery housing 10.

[0038] Please see Figure 1 and Figures 3-4 In some embodiments, the positioning frame 2 is further provided with symmetrical limiting mechanisms 7, which are used to engage with the grooves 40 on the left or right side walls of the lower battery housing 10. The limiting mechanisms 7 cooperate with the positioning mechanism 5 to further position the lower battery housing 10.

[0039] Please see Figures 4-5In some embodiments, the limiting mechanism 7 includes a limiting seat 71 fixed to the inner side of the positioning frame 2, a limiting pin 72 fixed to the limiting seat 71 and extending vertically, an elastic strip 73 fixed to the limiting seat 71 and extending horizontally, and a blocking tongue 74 rotatable around the limiting pin 72; the end of the elastic strip 73 is used to abut against the side wall of the blocking tongue 74; the blocking tongue 74 is used to engage in the groove 40 of the lower battery housing 10; the positioning frame 2 has a clearance hole, and the limiting seat 71 is located in the clearance hole. When loading the lower battery housing 10, the operator can press the lower battery housing 10 into the positioning frame 2 from front to back, so that the blocking tongue 74 engages in the groove 40. Specifically, the blocking tongue 74 is rotated around the limiting pin 72 by the deformation of the elastic strip 73, changing the position of the end of the blocking tongue 74. Similarly, the same working principle applies when unloading the lower battery housing 10. The above settings can limit the forward and backward movement of the lower battery housing 10, further preventing displacement of the lower battery housing 10.

[0040] Please see Figure 5 In some embodiments, the limiting seat 71 has a left-right extending waist-shaped hole 711, and the positioning frame 2 has a mounting hole corresponding to the waist-shaped hole 711. Positioning elements (not shown in the figure) are provided in the mounting holes and the corresponding waist-shaped holes 711. In practical applications, the positioning elements are screws / threads, which are screwed into the corresponding mounting holes and waist-shaped holes 711 to secure the limiting seat 71 to the positioning frame 2. This arrangement allows for fine-tuning of the position of the limiting seat 71 relative to the positioning frame 2, thereby ensuring that the blocking tongue 74 can accurately engage in the groove 40 on the lower battery housing 10.

[0041] Please see Figure 5 In some embodiments, the limiting seat 71 has a through hole extending to the left and right, and a screw 75 is disposed in the through hole. Two nuts 76 are threadedly connected to the body of the screw 75, and the two nuts 76 are respectively used to abut against the left side wall or the right side wall of the limiting seat 71; the end of the screw 75 is used to abut against the side wall of the positioning frame 2. Due to the setting of the waist-shaped hole 711, there is still a tendency for the limiting seat 71 to move in the left and right directions. Therefore, by setting the screw 75 and the nuts 76, the movement of the limiting seat 71 in the left and right directions is restricted.

[0042] Please see Figure 1In some embodiments, the outer wall of the positioning frame 2 is also provided with multiple sensors 21, all of which are used to detect whether the lower battery housing 10 is placed on the positioning frame 2. Specifically, in this embodiment, the number of sensors 21 is set to three: two sensors 21 are located on both sides of the upper part of the positioning frame 2, and one proximity sensor 21 is located in the middle of the lower part of the positioning frame 2. The sensors 21 are electrically connected to the control mechanism and transmit information on whether the material loading on the positioning frame 2 is completed to the control mechanism through signal transmission, thereby driving the control mechanism to control other mechanisms to start running, which can improve the automation level of the glue application device.

[0043] Please see Figure 1 and Figure 3 In some embodiments, a barcode scanning mechanism 8 is also provided on one side of the rotating mechanism 1. The barcode scanning mechanism 8 is used to identify the identification code on the lower battery housing 10. Since the manufacturing process of the lower battery housing 10 requires multiple steps, each step corresponds to an identification code. Therefore, after the staff loads the material, they need to use the barcode scanning camera in the barcode scanning mechanism 8 to identify the identification code on the lower battery housing 10 and enter it into the control system to achieve traceability.

[0044] In summary, this utility model solves the problem of sealing at the connection between the water nozzle 20 and the battery lower housing 10 by setting a rotating mechanism 1 to drive the lower battery housing 10 to rotate; setting a positioning mechanism 5 to determine the placement position of the lower battery housing 10; setting a pressing mechanism 6 to press the lower battery housing 10 onto the positioning frame 2; and setting a robotic arm 3 and a gluing mechanism 4 for fast and precise gluing.
