Description

Technical Field

[0001] This application relates to the field of battery casing assembly technology, specifically to a battery casing disassembly and assembly system. Background Technology

[0002] In electric vehicle assembly technology, the most crucial step is the installation of the power battery. Typically, the power battery is first mounted and secured to a battery bracket, then the entire assembly of the battery bracket and power battery is hoisted onto the vehicle's crossbeam. Finally, the battery cover is placed on top and connected to the crossbeam, and battery cables and other components are fixed in their designated positions. However, this current method of hoisting the battery cover results in it swaying unpredictably, making accurate positioning difficult. It generally requires manual intervention, is unsuitable for automation, and poses safety hazards. If the battery cover were to fall onto the battery assembly, it could damage the battery components. Utility Model Content

[0003] This utility model provides a battery cover disassembly and assembly system. Therefore, this utility model proposes a battery cover disassembly and assembly system to optimize the existing technology of disassembling and assembling battery covers by hoisting, so as to improve the positioning accuracy and disassembly and assembly safety of battery covers, and solve the problems of inaccurate positioning and safety hazards in the existing hoisting technology.

[0004] A battery casing assembly / disassembly system includes a working fork assembly that is parallel to and superimposed on a battery mounting plane. The working fork assembly includes two parallel transport forks, which are slidably connected to an X-axis sliding rail via a connecting rod and then connected to a Y-axis sliding rail via a slider. The X-axis sliding rail is perpendicular to the Y-axis sliding rail. The battery mounting plane includes an X-axis calibration mechanism consisting of a first cylinder, a second cylinder, and a push plate connecting the piston rods of the first and second cylinders. A magnetic suction element or an energized coil is embedded in the upper surface of the transport fork.

[0005] Optionally, the X-axis calibration mechanism is arranged in pairs, with the two push plates configured to move toward each other in the X-axis direction.

[0006] Optionally, the X-axis calibration mechanism further includes a lifting platform, which is lowered below the battery mounting plane, and the first cylinder, the second cylinder, and the upper surface of the lifting platform are connected by bolts.

[0007] Optionally, the transport fork further includes a telescopic arm, wherein the support planes on each telescopic rod of the telescopic arm that are used to contact the inner wall of the battery casing are coplanar.

[0008] Optionally, it also includes an AGV mobile vehicle, the top surface of which is horizontally positioned and used to hold the battery cover; the AGV mobile vehicle is equipped with a calibration device containing a camera.

[0009] Optionally, one of the links is connected to at least two transport forks.

[0010] The principle and beneficial effects of this utility model are as follows: This utility model provides a battery cover assembly / disassembly system. The system includes a working fork assembly, where the transport forks are used to move the battery cover from other locations to the battery installation position. During battery cover positioning calibration, two transport forks inside the battery cover push it towards a preset position to calibrate its lateral position. Additionally, at the installation position, a first and second cylinder control a push plate to push the battery cover to calibrate its front-to-back position. Therefore, inserting the battery cover into the battery cover from both ends prevents it from falling during transport. Furthermore, the transport forks and the X-axis calibration mechanism form a battery cover calibration mechanism, ensuring accurate positioning of the battery cover in both front-to-back and lateral directions. This structure, where the transport forks move and assist in calibration, significantly reduces the difficulty of calibrating the position of large battery covers and improves the safety of battery cover transport.

[0013] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in one embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Moreover, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. It should also be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities.

[0014] In electric vehicle assembly technology, the most crucial step is the installation of the power battery. Generally, this involves first fixing the power battery to a battery bracket, then hoisting the battery bracket and power battery together onto the vehicle's crossbeam. Finally, the battery cover is placed on top and connected to the crossbeam, and battery cables and other components are fixed in their designated positions. However, this existing method of hoisting the battery cover results in instability and difficulty in accurately positioning it. It typically requires manual intervention, is unsuitable for automation, and poses safety hazards. If the battery cover were to fall onto the power battery, it could damage the battery assembly. Therefore, this invention optimizes the design of a battery cover installation and removal system to improve the stability and safety of battery cover installation and removal.

[0015] like Figures 1 to 5 As shown, this utility model provides a battery cover disassembly and assembly system, including a working fork assembly 1 parallel to and above the battery mounting plane. The working fork assembly 1 includes two parallel transport forks 11. The transport forks 11 are slidably connected to an X-axis moving slide rail via a connecting rod and then connected to a Y-axis moving slide rail via a slider. The X-axis moving slide rail is perpendicular to the Y-axis moving slide rail. The battery mounting plane includes an X-axis calibration mechanism 2 composed of a first cylinder 21, a second cylinder 22, and a push plate 23 connecting the piston rods of the first cylinder 21 and the second cylinder 22. A magnetic suction element or an energized coil is embedded in the upper surface of the transport fork 11.

[0016] It should be noted that the X-axis calibration mechanism 2 is arranged in pairs, and the two push plates 23 are configured to move towards each other in the X-axis direction.

[0017] Reference Figure 2As shown, a battery cover with open ends is displayed. This battery cover is used to cover an assembled battery assembly. The battery holders in the battery assembly need to be fixedly connected to the battery cover. This embodiment does not specifically describe this connection; the purpose is to illustrate how to accurately place the battery cover on the battery assembly and how to prevent the battery cover from falling off and damaging the battery assembly during placement. Furthermore, the aforementioned left-right and front-back positions of the battery cover are relative, respectively... Figure 2 The four sides of the battery casing shown.

[0018] like Figure 3 and Figure 4 The diagram illustrates the calibration principle of the calibration battery cover in this invention: Assume the X-axis represents the front-to-back direction of the battery, and the Y-axis represents the left-to-right direction. During transport, the transport fork 11 moves along the X-axis and Y-axis sliding rails to the opening of the battery cover. The transport fork 11 is then moved along the X-axis to penetrate the battery cover. After adjusting the position of the transport fork 11 relative to the battery cover, the battery cover is lifted vertically and moved along the X-axis above the desired installation position before being lowered. At this point, the transport fork 11 is pushed along the Y-axis to move the battery cover to a preset position, completing the Y-axis positioning. Then, the first cylinder 21 and the second cylinder 22 are pushed along the X-axis to complete the X-axis positioning. After positioning in the horizontal plane, the transport fork 11 is removed from the battery cover. This control can be achieved by using a PLC to set control logic to automatically control the cylinder or lead screw motor that drives the transport fork 11. The control logic will not be elaborated in this embodiment; existing control technologies can be referenced.

[0019] The magnetic attachment on the transport fork 11 securely connects the battery cover to the transport fork 11, preventing the transport fork 11 from sliding relative to the battery cover during transport. Additionally, the energized coil generates magnetic poles at its two ends when energized, attracting the battery cover and thus securing it to the transport fork 11; this utilizes the principle of electromagnetism.

[0020] In addition, such as Figure 5 As shown, the transport fork 11 also includes a telescopic arm, and the support planes on each telescopic rod 3 of the telescopic arm that are used to contact the inner wall of the battery cover are coplanar. In this embodiment, a telescopic transport fork 11 is provided to adjust the length of the transport fork 11 extending into the battery cover, so that the transport fork 11 can be compatible with the transport of battery covers of various lengths, thus improving its compatibility. The coplanar design of the support planes on the telescopic rods 3 that are used to contact the inner wall of the battery cover ensures that the contact surface area between each telescopic rod 3 and the inner wall of the battery cover is equal, thereby improving the stability of the contact between the telescopic rods 3 and the inner wall of the battery cover.

[0021] Alternatively, one of the links can be connected to at least two transport forks 11. Increasing the number of transport forks 11 increases the contact surface area between the transport forks 11 and the inner surface of the battery casing. This not only prevents the battery casing from sliding relative to the surface of the transport forks 11 during transport, but also reduces the compressive stress of a single transport fork 11 on the battery casing, preventing deformation or dents on the surface of the battery casing due to excessive mass of the battery casing.

[0022] In some embodiments, the aforementioned X-axis calibration mechanism 2 further includes a lifting platform, which is recessed below the battery mounting plane. The first cylinder 21, the second cylinder 22, and the upper surface of the lifting platform are connected by bolts. In this embodiment, the lifting platform is provided so that the X-axis calibration mechanism 2, composed of the first cylinder 21, the second cylinder 22, and the push plate 23, can be recessed below the plane where the battery cover is placed, preventing interference between the push plates 23 at both ends and the battery cover when placing it, thus improving the convenience of placing the battery cover. This lifting platform adopts an existing cylinder structure.

[0023] In other embodiments, the present invention also includes an AGV mobile vehicle 4, the top surface of which is horizontally positioned and used to hold the battery cover; the AGV mobile vehicle 4 is equipped with a calibration device containing a camera. Figure 1 As shown, an AGV mobile vehicle 4 for transporting the battery cover from other locations is set to the left of the battery cover installation position. This mobile vehicle adopts the existing AGV trolley structure and uses a scanning device to scan the QR code in the route to control its movement path, which will not be described in detail in this embodiment. In addition, the main function of the AGV mobile vehicle 4 is to initially position the battery cover, aligning the battery cover with the battery position horizontally in terms of front-back and left-right positions, reducing the difficulty of calibrating the battery cover by the transport fork 11. The principle of initial positioning is that it has a calibration device inside, which includes a camera and a processing module. The camera takes pictures to obtain the position of the battery, and the processing module calculates the difference between the position captured by the camera and a preset position within a preset accuracy range. Based on the calculated difference, the rollers of the AGV mobile vehicle 4 are moved, thereby realizing the positioning of the battery cover.

[0024] Finally, the battery cover disassembly and assembly system provided by this utility model includes a working fork assembly 1, wherein the transport fork 11 is used to move the battery cover from other positions to the position where it is installed with the battery. When calibrating the position of the battery cover, the two transport forks 11 push it towards a preset position from inside the battery cover to calibrate its left and right positions. Additionally, at the installation position, the first cylinder 21 and the second cylinder 22 control the push plate 23 to push the battery cover to calibrate its front and rear positions. Thus, inserting the battery cover into the battery cover from both ends prevents it from falling during transport. Furthermore, the transport fork 11 and the X-axis calibration mechanism 2 form a mechanism for calibrating the battery cover, ensuring accurate positioning of the battery cover in the front-rear and left-right directions. This structure, where the transport fork 11 transports and assists in calibration, greatly reduces the difficulty of calibrating the position of large battery covers and improves the safety of battery cover transport.

[0025] The above embodiments merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
