Description

Technical Field

[0001] This utility model relates to the field of battery restraint and unrestraint technology, and in particular to a battery restraint and unrestraint system. Background Technology

[0002] The rapid development of new energy vehicles has placed higher comprehensive demands on power batteries, among which improving driving range is particularly crucial. Increasing the driving range of new energy vehicles requires increasing the energy density of power batteries. However, when the energy density of power batteries breaks through to new levels, the intense electrochemical reactions during the formation process significantly exacerbate gas production. If timely venting and drainage are not carried out, a pressure gradient will form inside the cell. Continuous pressure accumulation will not only cause irreversible deformation of the battery casing but also lead to uneven pressure distribution between the electrodes and the separator, creating a risk of localized hot spots.

[0003] Therefore, the industry commonly uses restraint trays to physically limit the power batteries, thereby controlling battery expansion and reducing hotspot risks during critical stages such as formation and settling. The restraint-adding / unrestraining device is used to press the power batteries within the restraint tray or release them from the tray to remove them. Depending on the number and specifications of the power batteries, the device requires twisting the restraint tray's screws to push / pull its pressure plate to perform the corresponding restraint and unrestraint operations. Due to the large number of batteries produced, manually operating the restraint-adding / unrestraining device is inefficient and slow. Furthermore, the process requires frequent movement of the restraint tray containing the batteries to be restrained / unrestrained, which is time-consuming and labor-intensive, hindering battery production efficiency.

[0029] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] This embodiment discloses a battery restraint system to automatically transfer and automatically apply / relieve restraints on the battery and the restraint tray on which the battery is assembled, thereby improving production efficiency, reducing transfer and restraint application / relief operation costs, and increasing production capacity. Please refer to... Figure 1 , Figure 3 and Figures 6 to 8 As shown, the battery restraint system of this embodiment includes a conveying and lifting device 1 and a restraint device 2. The restraint device 2 is mounted on the conveying and lifting device 1. The conveying and lifting device 1 is used to drive the restraint tray containing the battery to move back and forth or move up and down.

[0031] The restraint device 2 includes a restraint frame 21 and a drive mechanism 22. The drive mechanism 22 is fixed on the restraint frame 21. The drive mechanism 22 includes a pushing structure 221 and a turning structure 222. The pushing structure 221 can extend and retract relative to the restraint tray to abut or separate one end of the restraint tray from the restraint frame 21.

[0032] The screwing structure 222 is disposed on the pushing structure 221 for pushing one end of the restraint tray. The screwing structure 222 is used to drive the screw of the restraint tray to rotate in order to restrain / unrestrain the battery in the restraint tray.

[0033] The working principle of the battery restraint system of this embodiment is illustrated by a specific example. In this embodiment, the conveying and lifting device 1 is used to: (1) convey the battery to be restrained / unrestrained and the restraint tray on which the battery is assembled to the restraint device 2 for restraint / unrestraint; (2) convey the battery and the restraint tray after restraint / unrestraint to the restraint device 2. The restraint / unrestraint device 2 is mounted above the conveying and lifting device 1. The battery to be restrained / unrestrained, together with the restraint tray, is first sent by the conveying and lifting device 1 to the underside of the restraint / unrestraint device 2, and then lifted by the conveying and lifting device 1 to the restraint / unrestraint device 2 for restraint / unrestraint operation. The restraint-adding / unbinding device 2 includes a restraint frame 21 and a drive mechanism 22. The drive mechanism 22 is fixed to the restraint frame 21 and includes a pushing structure 221 and a turning structure 222. The pushing structure 221 selectively pushes the restraint tray against the restraint frame 21, causing the restraint tray to abut against and be pressed into the restraint frame 21, preventing shaking and enhancing the stability of the restraint tray during the restraint-adding / unbinding process, ensuring the smooth operation of the restraint-adding / unbinding process. The turning structure 222 is used to drive the screw of the restraint tray to rotate. Different directions of screw rotation will change the tightness of the battery in the restraint tray. Through the turning mechanism, the automatic restraint-adding / unbinding of the battery in the restraint tray can be achieved. After the restraint-adding / unbinding operation is completed, the conveying and lifting device 1 controls the battery and the restraint tray to descend, and finally delivers them out through the conveying and lifting device 1.

[0034] In summary, the battery restraint system of this embodiment integrates a conveyor lifting device 1 and a restraint device 2 to achieve fully automated transportation and rapid restraint operation of batteries within the restraint tray. The conveyor lifting device 1 can intelligently match the restraint requirements of batteries and accurately deliver them to the workstation, significantly reducing manual handling costs and improving logistics efficiency. The restraint device 2 adopts a push-twist linkage design. After the restraint tray is fixed by the restraint frame 21, the screw is driven synchronously to complete the locking / releasing action, greatly improving the automation level and work efficiency of battery restraint operation. This effectively solves the problems of low efficiency and poor consistency of traditional manual operation, achieving the production goal of cost reduction and efficiency improvement.

[0035] Optionally, see Figures 3 to 5 As shown, the conveying and lifting device 1 includes a conveyor line 11 and a lift 12. The conveyor line 11 is used to drive the restraint tray located thereon to move back and forth, and the lift 12 is used to drive the restraint tray located thereon to move up and down. The lift 12 is detachably installed in the conveyor line 11.

[0036] Furthermore, the elevator 12 includes a lifting platform 121 and a lifting assembly 122. The lifting platform 121 is mounted above the lifting assembly 122, and the lifting assembly 122 can drive the lifting platform 121 to perform lifting movements, so that the lifting platform 121 has a first state position and a second state position: in the first state position, the lifting platform 121 is embedded in the conveyor line 11; in the second state position, the lifting platform 121 is vertically separated from the conveyor line 11. In this embodiment, the lifting assembly 122 is a cylinder, the top of the cylinder is connected to the lifting platform 121, and the cylinder is also equipped with a guide rod to guide the lifting direction of the cylinder. The elevator 12 is driven by a servo motor.

[0037] Optionally, see Figure 7 As shown, the pushing structure 221 includes a pushing rod frame 2211, a telescopic drive rod 2212 fixedly connected to the pushing rod frame 2211, and a driver 2213 mounted on the pushing rod frame 2211 and fixedly connected to the telescopic drive rod 2212. A screwing structure 222 is disposed at one end of the pushing rod frame 2211 used to push the restraint tray. The driver 2213 is used to drive the telescopic drive rod 2212 to perform telescopic movement, thereby causing the pushing rod frame 2211 to push the restraint tray or separate from the restraint tray. In this embodiment, the telescopic drive rod 2212 is a lead screw.

[0038] Optionally, see Figure 8 As shown, the screwing structure 222 includes a screwing head 2221, a first driving member 2222, a linear slide rail 2223, and a second driving member 2224. The screwing head 2221 is fixedly connected to the first driving member 2222, and the first driving member 2222 is fixedly connected to the second driving member 2224. The second driving member 2224 is slidably mounted on the linear slide rail. The first driving member 2222 is used to drive the screwing head 2221 to rotate, and the second driving member 2224 is used to drive the screwing head 2221 and the first driving member 2222 to move closer to or away from the restraint tray along the linear slide rail. In this embodiment, when the pushing structure 221 presses the restraint tray against the restraint frame 21, the turning structure 222 then drives the turning head 2221 to approach the screw of the restraint tray through the second driving member 2224 inside, so that the turning head 2221 is fully engaged with the screw, thereby realizing the tightening / unscrewing operation. The turning head 2221 is preferably a hexagonal structure adapted to the screw head, the first driving member 2222 is preferably a motor, and the second driving member 2224 is preferably a cylinder.

[0039] Optionally, see Figure 1 and Figure 2 As shown, the conveyor lifting device 1 is installed in a working frame 3, and the restraint device 2 is installed on the top of the working frame and directly opposite the conveyor lifting device 1.

[0040] Furthermore, see Figure 2As shown, the working frame 3 is also equipped with a tray support 31, which can selectively provide support for the restraint tray that has been raised into the restraint frame 21. In this embodiment, the tray support 31 is located at a relative position on both sides of the working frame 3. The tray support 31 is driven by a cylinder and can perform telescopic movements. When the restraint tray is sent to the restraint-releasing device 2 by the conveying lifting device 1, the tray support 31 extends to support the restraint tray from the bottom. When the battery completes the restraint-releasing process, the tray support 31 retracts, and the restraint tray falls back to the lifting platform 121, whereby it is driven by the lifting platform 121 to descend back onto the conveyor line 11 and be sent out.

[0041] Furthermore, see Figures 1 to 2 as well as Figures 6 to 7 As shown, the restraint frame 21 and the push rod frame 2211 are also equipped with a first detection device 23 for detecting the height of the battery in the restraint tray, and the working condition carrier 3 is also equipped with a second detection device 32 for detecting the position of the restraint tray. In this embodiment, the first detection device 23 is used to detect the height of the battery before restraining it, to prevent the battery height from being too high and affecting the subsequent battery production process. The first detection device 23 can notify the operator to adjust the battery according to the detection result. The second detection device 32 is used to detect whether there is a restraint tray in the restraint frame 21 and detect its position, thereby activating the push structure 221 and the screwing structure 222 to restrain / unrestrain the battery.

[0042] Optionally, see Figures 1 to 3 As shown, the working frame 3 is also provided with a baffle plate 33, which is configured to rise when the restraint tray is conveyed to the lifting platform 121, so that the restraint tray is located at a preset position on the lifting platform 121.

[0043] Optionally, see Figure 6 and Figure 7 As shown, the push rod holder 2211 is also equipped with a pressure sensor 24 for monitoring the magnitude of the pressure applied by the push rod holder 2211 to the restraint tray. The pressure sensor 24 can display the magnitude of the restraint / unrestraint force, which facilitates the analysis of the pressure related to the restraint and unrestraint of the battery, and helps to control and analyze battery data, thereby improving the battery production process.

[0044] In this embodiment, since the restraint tray often arranges the power batteries in two rows, and the cells of different batches of power batteries have thickness tolerances, using a single drive mechanism 22 for restraint can easily cause uneven pressure on the two rows of batteries, forming a "seesaw effect" and causing localized damage to the power batteries. The restraint system of this embodiment is set up with two corresponding drive mechanisms 22 to independently restrain / unrestrain the two rows of batteries in the restraint tray, which better meets the restraint and unrestraint requirements of each row of batteries.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Meanwhile, the above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
