[0002] With the rapid development of the new energy electric vehicle market, more and more automobile manufacturing enterprises have entered the field of new energy vehicles, and the number of new energy vehicles has increased significantly, driving the rapid development of battery technology. In the process of battery production, the use of battery charging and discharging equipment is crucial. Through these equipment, the battery is charged and discharged to realize the formation and grading processes, thereby activating the battery. Among them, the restraint tray, as a key device for fixing and supporting the battery, ensures the stable position of the battery during the formation process and is an indispensable important link in the battery production process.

[0003] However, the restraint tray in the prior art has the problem of inaccurate positioning, resulting in the deviation of the lithium battery from its corresponding probe, affecting the safety of the charging and discharging process. In addition, during the long-term high-current charging and discharging process of the battery, the battery will inevitably have abnormalities and may even cause safety accidents. The existing restraint tray cannot drive the battery to quickly fall into the water tank submerged fire protection component in time, so the water fire protection function of the battery cannot be implemented in time, seriously affecting the safety and efficiency of battery production. Summary of the Utility Model

[0004] The purpose of the present application is to provide a restraint tray positioning structure and a battery formation device for the deficiencies in the above-mentioned prior art.

The limit component has a first position where it cooperates and is clamped with the support component and a second position where it is disengaged from the support component. A limit groove is provided on the support component, and a limit protrusion is provided on the limit component.

[0016] The beneficial effects of this application include:

[0017] The present application provides a positioning structure for a restraint tray, which includes a support component for supporting the restraint tray and a limit component movably arranged on the support component.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. Components of the embodiments of this application usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of this application that is claimed, but merely represents selected embodiments of this application. It should be noted that, without conflict, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0025] In the description of this application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this application is usually placed when in use. It is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application. In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0026] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging vertically, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0027] In the description of this application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0028] On the one hand of the embodiments of this application, a restraint tray positioning structure is provided, as Figure 1and Figure 2 As shown in Figure 2 , it includes a support assembly 20 for supporting and restraining the tray 10 and a limit assembly 30 movably arranged on the support assembly 20. The limit assembly 30 has a first position that cooperates and is snap-connected with the support assembly 20 and a second position that releases the snap connection with the support assembly 20. A limit groove 21 is provided on the support assembly 20, and a limit protrusion 31 is provided on the limit assembly 30. When the limit assembly 30 is in the first position, the limit protrusion 31 cooperates and is snap-connected with the limit groove 21. When the limit assembly 30 is in the second position, the limit protrusion 31 releases the snap connection with the limit groove 21, and the limit assembly 30 is driven to switch between the first position and the second position.

[0029] Specifically, during the normal charge and discharge process of the battery, the limit assembly 30 is in the first position. Through the cooperation and snap connection between the limit protrusion 31 and the limit groove 21, it is ensured that the support assembly 20 and the restraint tray 10 are stably fixed in the designated position, thereby effectively restraining the battery and ensuring the safety and stability of the charge and discharge process.

[0030] However, abnormal situations may occur during the charge and discharge process of the battery, such as a fire. When such an abnormal situation occurs, the limit assembly 30 will be driven by an external force and switch from the first position to the second position, that is, the limit protrusion 31 releases the snap connection with the limit groove 21. At this time, the support assembly 20 and the restraint tray 10 will be quickly submerged in the water tank under the drive of the restraint tray lifting structure for fire protection treatment to effectively ensure the safety of the battery and the surrounding environment.

[0031] When the charge and discharge process of the battery returns to normal, the limit assembly 30 is driven again by the restraint tray lifting structure and switches back from the second position to the first position, so that the support assembly 20 and the restraint tray 10 can return to the stable fixed position again, continue to effectively restrain the battery, and ensure the normal progress of the subsequent charge and discharge process.

[0032] Through the restraint tray positioning structure provided by the present application, not only the safety during the charge and discharge process of the battery is improved, but also it is ensured that emergency treatment can be quickly carried out in case of abnormal situations, significantly enhancing the reliability and stability of the overall system.

[0033] Optionally, the restraint tray positioning structure further includes a first driving member 40 drivingly connected to the limit assembly 30, and the first driving member 40 drives the limit assembly 30 to switch between the first position and the second position.

[0034] Specifically, as shown in Figure 1 and Figure 2As shown in the figure, by connecting with the limiting component 30, the first driving member 40 can accurately control the position of the limiting component 30. When the battery is in a normal charge and discharge state, the first driving member 40 keeps the limiting component 30 at the first position, so that the limiting protrusion 31 is in close fit with the limiting groove 21, thereby ensuring the stable positions of the restraint tray 10 and the battery and ensuring the safety of the charge and discharge process. During the charge and discharge process of the battery, in case of abnormal situations such as a fire, the first driving member 40 will respond quickly and drive the limiting component 30 to switch from the first position to the second position. Such a design can achieve an emergency response in a very short time, effectively prevent the spread of accidents, and ensure the safety and efficiency of the battery production process. It should be noted that the first driving member 40 can be a cylinder or other driving structures, such as an electric push rod, a hydraulic cylinder or a mechanical transmission device, etc. The present application does not limit the type of the first driving member 40.

[0035] It should be understood that the first driving member 40 should be connected to the controller of the battery formation equipment to form an efficient monitoring and response mechanism. The controller monitors the state of the battery during the charge and discharge process in real time, collects data through various sensors and detection devices, and ensures that the operation of the battery is always within a safe range. If the system detects any abnormality, such as too high temperature, abnormal current fluctuation or abnormal reaction inside the battery, the control system will immediately control the first driving member 40 to quickly switch the state of the limiting component 30, switching it from the first position to the second position. This switching action releases the clamping connection between the limiting component 30 and the support component 20, so that the support component 20 and the restraint tray 10 can fall into a preset water tank for submerged fire fighting treatment, quickly extinguish the fire or control the spread of the accident.

[0036] Optionally, the limiting component 30 includes a guide sleeve 32 and a limiting rod 33 slidably disposed in the guide sleeve 32. The limiting protrusion 31 is disposed at the end of the limiting rod 33, and the limiting rod 33 is driven to slide along the axial direction of the guide sleeve 32.

[0037] Specifically, as Figure 2 shown, the guide sleeve 32 is fixedly disposed on other components of the battery formation equipment, providing a stable guiding structure. The limiting rod 33 can slide stably along the axial direction of the guide sleeve 32 to switch between the first position and the second position. The limiting protrusion 31 is disposed at the end of the limiting rod 33 close to the support component 20, and its size and shape should match the limiting groove 21 on the support component 20. During the normal charge and discharge process of the battery, the limiting rod 33 is driven by the first driving member 40 to the first position, and the limiting protrusion 31 is tightly embedded in the limiting groove 21, thereby realizing effective limitation of the support component 20. When an abnormality occurs during the charge and discharge process of the battery, the first driving member 40 responds quickly and drives the limiting rod 33 to slide to the second position, and the limiting protrusion 31 is disengaged from the limiting groove 21, thereby not affecting the subsequent actions of the support component 20 and the restraint tray 10.

[0038] Optionally, the restraint tray positioning structure further includes a connecting member 60 , and the first driving member 40 is drivingly connected to the limiting assembly 30 via the connecting member 60 .

[0039] Specifically, Figure 2 As shown, the connecting member 60 plays an important transmission role, which can effectively transmit the driving force of the first driving member 40 to the limiting rod 33, ensuring that the movement of the limiting assembly 30 is accurate and reliable. In the embodiment of the present application, the connecting member 60 can be a connecting plate. When the first driving member 40 (such as a cylinder or an electric push rod) is started, its driving force is transmitted to the limiting rod 33 through the connecting plate. The movement of the connecting plate drives the limiting rod 33 to slide axially along the guide sleeve 32, thereby realizing the engagement or release of the limiting protrusion 31 and the limiting groove 21. Through the use of the connecting plate, the system can achieve a smooth and continuous driving process, avoiding the impact and vibration that may be caused by direct drive, and further improving the stability and life of the system.

[0040] Optionally, the support assembly 20 includes a guide rail assembly 22 and a support plate 23 slidably disposed on the guide rail assembly 22, the limit assembly 30 is movably disposed on the guide rail assembly 22, the restraint tray 10 is disposed on the side of the support plate 23 away from the guide rail assembly 22, and the movement direction of the limit assembly 30 is perpendicular to the movement direction of the support plate 23.

[0041] Specifically, Figure 2 As shown, the guide rail assembly 22 provides a smooth and low-friction sliding path to ensure that the support plate 23 can slide freely along a predetermined direction. The support plate 23 cooperates with the guide rail assembly 22 to support and move the restraint tray 10 at a fixed height. The limit assembly 30 is connected to the guide rail assembly 22 and can move freely on the guide rail assembly 22.

[0042] In addition, the movement direction of the limiting assembly 30 is perpendicular to the movement direction of the support plate 23. Therefore, when the limiting assembly 30 is in the first position, the limiting protrusion 31 and the limiting groove 21 can be engaged to limit the guide rail assembly 22, so that the guide rail assembly 22 will not be displaced along its axial direction due to unreliable connection. This vertical limiting method can effectively avoid any potential displacement error caused by the movement of the guide rail assembly 22, and ensure the precise positioning of the restraint tray 10.

[0043] Optionally, the guide rail assembly 22 includes a fixing seat 221 and a guide rail 222 fixed to the fixing seat 221 , the limiting groove 21 is disposed on the fixing seat 221 , and the support plate 23 is slidably disposed on the guide rail 222 .

[0044] Specifically, Figure 2As shown in the figure, the fixed seat 221 is fixedly arranged on the lifting plate 70 of the restraint tray lifting structure, so that it can stably support the guide rail 222, the support plate 23 and the restraint tray 10. Moreover, the fixed seat 221 serves as the base of the support assembly 20. The restraint tray lifting structure can drive the fixed seat 221 to lift through the lifting plate 70, and then make the guide rail 222, the support plate 23 and the restraint tray 10 lift together to realize the overall lifting function. The limit groove 21 is arranged on the fixed seat 221, so that the limit protrusion 31 of the limit assembly 30 is engaged or disengaged with the limit groove 21 of the fixed seat 221, thereby realizing the limitation or release of the limitation of the support plate 23. The support plate 23 can be slidably arranged on the guide rail 222 through a plurality of sliders 223, so that the support plate 23 can slide smoothly along the guide rail 222.

[0045] It should be noted that the guide rail 222 is a linear guide rail, which can be one arranged in the middle or two symmetrically arranged. When there are two guide rails 222, these two guide rails 222 can be symmetrically arranged at the bottom of the restraint tray 10 along the length direction of the restraint tray 10. The number and position of the fixed seats 221 correspond to those of the guide rail 222. Such a design can better support and stabilize the whole structure. In this double-guide-rail 222 design, one or more limit grooves 21 are arranged on one side of each fixed seat 221 opposite to the other fixed seat 221, that is, the limit assembly 30 is arranged outside the restraint tray 10. Correspondingly, the same number of limit assemblies 30 need to be arranged. The configuration mode of the limit assembly 30 limits the displacement of the fixed seat 221 and the guide rail 222 along their axial directions symmetrically on both sides of the guide rail 222, and further ensures the stability of the whole support assembly 20 in the direction perpendicular to the axial direction of the guide rail 222.

[0046] Optionally, at least part of the edge of the orthographic projection of the restraint tray 10 on the support plate 23 coincides with the edge of the support plate 23.

[0047] Specifically, first, the restraint tray 10 is conveyed onto the support plate 23 by an external stacker device, and then through adjustment, at least part of the edge of the orthographic projection of the restraint tray 10 on the support plate 23 coincides with the edge of the support plate 23, so as to realize the precise positioning and stable support of the restraint tray 10. It should be noted that the support plate 23 can be designed as a whole plate or two plates symmetrically arranged at the bottom of the restraint tray 10.

[0048] When the support plate 23 is a whole plate, its size is the same as that of the restraint tray 10 for easy positioning. Through adjustment, the edge of the orthographic projection of the restraint tray 10 on the support plate 23 can completely coincide with the edge of the support plate 23 to realize the edge alignment of the two. Such a design can adopt either a single guide rail 222 or a double guide rail 222 to ensure the stability and positioning accuracy of the restraint tray 10.

[0049] To save materials, the support plate 23 can also be designed as two plates symmetrically arranged at the bottom of the restraint tray 10. At this time, the total area of the two plates is smaller than the area of a single whole plate. The two plates are respectively slidably arranged on the corresponding guide rails 222, and stable support for the restraint tray 10 is achieved through symmetrical layout. The distance between the two plates is designed according to the size of the restraint tray 10, so that at least part of the edge of the orthographic projection of the restraint tray 10 on the support plate 23 coincides with the edge of the support plate 23, ensuring the accuracy of positioning.

[0050] Optionally, the support assembly 20 further includes a plurality of guide brackets 24, and the plurality of guide brackets 24 are spaced apart on the edge of the support plate 23, and the edge of the restraint tray 10 abuts against the guide brackets 24.

[0051] Specifically, as Figure 2 shown, after aligning the restraint tray 10 with the support plate 23, the guide brackets 24 are spaced reasonably by arranging a plurality of guide brackets 24 at intervals on the four peripheral edges of the support plate 23, so that the restraint tray 10 can naturally slide in and be caught by the guide brackets 24 during the placement process. Effectively avoid the possible deviation of the restraint tray 10 during the movement process and ensure that it is always in the correct position. Thus, during the charging and discharging process of the battery, since the restraint tray 10 is always accurately positioned, the battery and its corresponding probes can also maintain good contact, ensuring the safety and stability of the charging and discharging process. This design effectively solves the safety hazards caused by the inaccurate position of the restraint tray 10 in the prior art and significantly improves the reliability of the battery production process. In addition, the setting of the guide brackets 24 also simplifies the operation process. When placing the restraint tray 10 on the support plate 23, just push it between the guide brackets 24, and the edge of the restraint tray 10 will automatically align with the edge of the support plate 23. This automatic alignment mechanism reduces the time and error of manual adjustment and improves the production efficiency.

[0052] Optionally, the restraint tray positioning structure further includes a second driving member 50 drivingly connected to the support plate 23, and the second driving member 50 drives the support plate 23 to slide along the axial direction of the guide rail assembly 22.

[0053] Specifically, as Figure 2As shown, after the restraint tray 10 is preliminarily aligned with the support plate 23, the second driving member 50 is activated to push the support plate 23 and the restraint tray 10 forward by an appropriate distance (such as 10 mm, 15 mm). This fine-tuning process is carried out along the axial direction of the guide rail 222, so that one side of the restraint tray 10 abuts against the second driving member 50, and the other side abuts against the lifting tailstock pressure structure. At this time, the restraint tray 10 is stably fixed and will not slide axially along the guide rail 222. At this time, the necessary pressure can be applied to the battery through the restraint structure to ensure that the battery is in a stable state during the charge and discharge process, achieving the restraint function.

[0054] By providing the second driving member 50, the support plate 23 and the restraint tray 10 can achieve high-precision axial sliding, ensuring the accuracy and stability of the position of the restraint tray 10, and improving the safety and stability during the charge and discharge process of the battery. Similarly, the second driving member 50 can be a cylinder, or other driving structures such as an electric push rod, a hydraulic cylinder or a mechanical transmission device, etc. The present application does not limit the type of the second driving member 50.

[0055] On the other hand, an embodiment of the present application provides a battery formation device, including a restraint tray 10 and the restraint tray positioning structure of any one of the above. The restraint tray 10 is placed on the support assembly 20 of the restraint tray positioning structure. Since the battery formation device adopts the restraint tray positioning structure of any one of the above, it also has the same beneficial effects, which can be specifically referred to the previous description and will not be elaborated here.

[0056] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
