DETAILED DESCRIPTION

Please refer to FIG. 1 to FIG. 4. A pressurizing apparatus 1 and a battery tray 2 are shown in the figures. The pressurizing apparatus 1 comprises a base 10, a compressive force generation module 11, a fixing module 12, and a controller 13. The compressive force generation module 11 and the fixing module 12 are arranged on the base 10, and the controller 13 is electrically connected to the compressive force generation module 11 and the fixing module 12.

In some embodiments, the battery tray 2 comprises a frame 20, a pressurizing plate 21, a pressure-bearing plate 22, a plurality of partition plates 23, and four springs 24. The pressurizing plate 21, the pressure-bearing plate 22, and the plurality of partition plates 23 are coupled to the frame 20, so that the pressurizing plate 21, the pressure-bearing plate 22, and the plurality of partition plates 23 are movable with respect to the frame 20. The springs 24 are arranged between the pressurizing plate 21 and the pressure-bearing plate 22. In some embodiments, the battery tray 2 is configured to load soft-packed lithium batteries; that is, a soft-packed lithium battery (not shown) is fixed on each of two sides of each of the plurality of partition plates 23, and the frame 20 comprises a fixing plate 200.

Please refer to FIG. 1 to FIG. 8, in which FIG. 5 to FIG. 8 illustrate implementations of a first embodiment of the pressurizing apparatus 1 for the battery tray 2. As shown in FIG. 5 to FIG. 8, in the present embodiment, the compressive force generation module 11 of the pressurizing apparatus 1 for the battery tray 2 comprises a mounting base 110 and a thrust generator 111. The mounting base 110 is coupled to the base 10, and the thrust generator 111 is arranged on the mounting base 110. In some embodiments, the fixing module 12 comprises a pair of locking arms 120, while the present disclosure is not limited thereto. The fixing module 12 may comprise a single or a plurality of locking arms 120.

In the present embodiment, in response to that the pressurizing apparatus 1 for the battery tray 2 starts to operate, the controller 13 controls the fixing module 12 to be coupled between the compressive force generation module 11 and the frame 20 of the battery tray 2. In some embodiments, the fixing module 12 is coupled between the compressive force generation module 11 and the frame 20 of the battery tray 2 by configuring one of two ends of each of the pair of locking arms 120 to be engaged with the mounting base 110 and the other end of each of the pair of locking arms 120 to be engaged with the fixing plate 200.

In some embodiments, the fixing module 12 further comprises a pair of actuators 121, and the pair of actuators 121 are coupled to the base 10 and electrically connected to the controller 13. The pair of actuators 121 are respectively coupled to the corresponding locking arm 120, and the controller 13 controls the pair of actuators 121 of the fixing module 12 to drive the pair of locking arms 120 to move close to or away from the mounting base 110 and the fixing plate 200. In some embodiments, in response to that the controller 13 controls the fixing module 12 to be coupled between the compressive force generation module 11 and the frame 20, the controller 13 controls the pair of actuators 121 to drive the pair of locking arms 120 to move close to the mounting base 110 and the fixing plate 200, so that one of two ends of each of the pair of locking arms 120 is engaged with the mounting base 110 and the other end of each of the pair of locking arms 120 is engaged with the fixing plate 200.

In some embodiments, the fixing module 12 further comprises a first sliding member 122 and a second sliding member 123. The first sliding member 122 is coupled to the pair of locking arms 120, and the second sliding member 123 is arranged between the first sliding member 122 and the base 10 and coupled to the pair of actuators 121. In some embodiments, the pair of locking arms 120 can slide along a first direction D1 through the first sliding member 122. In addition, in response to that the pair of actuators 121 are activated, the pair of locking arms 120 can move along a second direction D2 through the second sliding member 123.

In some embodiments, in response to that the fixing module 12 is arranged between the compressive force generation module 11 and the frame 20, the controller 13 controls the compressive force generation module 11 to apply a compressive force to the pressure-bearing plate 22 of the battery tray 2 to make the pressure-bearing plate 22 press the pressurizing plate 21 through the four springs 24, thereby forming a containment on the at least one battery on each of the plurality of partition plates 23.

Specifically, in some embodiments, the compressive force generation module 11 applies the compressive force to the pressure-bearing plate 22 of the battery tray 2 using the thrust generator 111. One of two ends of the thrust generator 11 has a pressurizing head 114 and a telescopic member 115, and the pressurizing head 114 faces the first direction D1 and one side surface of the pressure-bearing plate 22 of the battery tray 2 (as shown in FIG. 4). In some embodiments, in response to that the compressive force generation module 11 applies the compressive force to the pressure-bearing plate 22 of the battery tray 2, the telescopic member 115 of the compressive force generation module 11 extends to make the pressurizing head 114 contact the pressure-bearing plate 22 and gradually apply the compressive force to the pressure-bearing plate 22. After that, the battery tray 2 is slightly moved away from the direction of the pressurizing head 114 (the first direction D1), so that one of two ends of the pair of locking arms 120 is tightly engaged with the fixing board 200.

In some embodiments, in response to that the battery tray 2 is slightly moved away from the direction of the pressurizing head 114 (the first direction D1), the pair of locking arms 120 may be driven by the fixing plate 200. Therefore, the pair of locking arms 120 slide along the first direction D1 through the first sliding member 122, so that the other end of the pair of locking arms 120 is tightly engaged with the mounting base 110. At this moment, since one of two ends of the pair of locking arms 120 is engaged with the fixing plate 200 and the other end of the pair of locking arms 120 is engaged with the mounting base 110, the distance between the compressive force generation module 11 and the battery tray 2 is maintained within a specific range which is a length of the pair of locking arms 120 in the first direction D1. Therefore, in response to that the compressive force generation module 11 continues to apply the compressive force to the battery tray 2, the battery tray 2 will no longer be moved, thereby facilitating the continuous application of the compressive force.

In some embodiments, in response to that the compressive force generation module 11 applies the compressive force to the pressure-bearing plate 22, the pressure-bearing plate 22 transmits the compressive force to the pressurizing plate 21 through the four springs 24, so that the pressurizing plate 21 pressurizes and shapes the batteries (not shown) arranged on the plurality of partition plates 23. In some embodiments, before the compressive force generation module 11 applies the compressive force to the battery tray 2, the four springs 24 can apply the compressive force to the pressurizing plate 21 in advance to make the plurality of partition plates 23 be closely attached with each other and make the batteries be shaped slightly. In addition, the four springs 24 can provide a buffering effect to prevent the pressurizing head 114 from directly impacting the pressurizing plate 21 and prevent the compressive force generation module 11 from exerting excessive force.

In some embodiments, in response to that the formation process for the batteries is finished, the operation of the pressurizing apparatus 1 for the battery tray 2 is stopped, and the controller 13 controls the pair of actuators 121 to drive the pair of locking arms 120 to move away from the mounting base 110 and the fixing plate 200. In some embodiments, the pair of locking arms 120 can slide along the second direction D2 through the second sliding member 123, thereby making the pair of locking arms 120 move away from mounting base 110 and the fixing plate 200 to ensure that the pair of locking arms 120 do not continue to be engaged with the mounting base 110 and the fixing plate 200.

As shown in FIG. 5 and FIG. 6, the compressive force generation module 11 further comprises a displacement generation unit 112 and a guide rail 113. The displacement generation unit 112 and the guide rail 113 are arranged on the base 10, and the mounting base 110 is coupled to the guide rail 113. In some embodiments, the displacement generation unit 112 is electrically connected to the controller 13 and is controlled to drive the mounting base 110 to slide. In some embodiments, in response to that the compressive force is to be applied to the battery tray 2, the controller 13 controls the displacement generation unit 112 to drive the mounting base 110 to slide away from the battery tray 2 to ensure that the mounting base 110 is engaged with the other end of the pair of locking arms 120; in response to that the formation process of the batteries is finished, the controller 13 controls the mounting base 110 to slide close to the battery tray 2 to ensure that the mounting base 110 is detached from the pair of locking arms 120.

As shown in FIG. 7 and FIG. 8, the fixing module 12 further comprises a bearing plate 124 and an elastic member 125, and the bearing plate 124 is arranged between the first sliding member 122 and the second sliding member 123. In some embodiments, each of the pair of actuators 121 comprises a moveable portion 127, and each of the pair of locking arms 120 comprises a stopping portion 126. The moveable portion 127 is coupled to the bearing plate 124, and the elastic member 125 is arranged between the bearing plate 124 and the stopping portion 126. Accordingly, through the configuration of the elastic member 125, in response to that the operation of the pressurizing apparatus 1 for the battery tray 2 is stopped, the pair of locking arms 120 can be ensured to move to an initial position resiliently; that is, the pair of locking arms 120 are moved resiliently along the first direction D1. Therefore, in some embodiments, the pair of actuators 121 in the first direction D1 can be omitted.

Please refer to FIG. 1 to FIG. 4 and FIG. 9 to FIG. 12, in which FIG. 9 to FIG. 12 illustrate implementations of a second embodiment of the pressurizing apparatus 1 for the battery tray 2. One of the differences between the second embodiment and the first embodiment is and the configuration and the arrangement of the fixing module 12. Specifically, as shown in FIG. 9 to FIG. 12, the pair of actuators 121 are arranged on the base 10 and electrically connected to the controller 13. The pair of locking arms 120 are arranged on the first sliding member 122, and the second sliding member 123 is arranged between the first sliding member 122 and the base 10 and coupled to the pair of actuators 121.

In some embodiments, the fixing module 12 further comprises a pivoting member 128, which may be a ball bearing arranged between the first sliding member 122 and the second sliding member 123. Therefore, the first sliding member 122 and the second sliding member 123 are pivotally rotated with respect to each other through the pivoting member 128. In addition, one of two ends of the pair of locking arms 120 is hinged to the mounting base 110 through a hinge member 129, which may also be a ball bearing. Therefore, in some embodiments, in response to that the controller 13 controls the pair of actuators 121 to drive the pair of locking arms 120 to move, only the end of the locking arm 120 far away from the mounting base 110 can move close to or away from the fixing plate 200; that is, each of the pair of locking arms 120 performs a swinging motion. At this moment, the pair of locking arms 120 can slide along the first direction D1 through the first sliding member 122 and slide along the second direction D2 through the second sliding member 123. In addition, the configuration of the pivoting member 128 and the hinge member 129 allows the pair of locking arms 120 to be rotated during the swinging motion of the pair of locking arms 120.

In the present embodiment, before the pressurizing apparatus 1 for the battery tray 2 applies the compressive force to the battery tray 2, one of two ends of the pair of locking arms 120 is engaged with the fixing plate 200 of the battery tray 2 to ensure that the distance between the compressive force generation module 11 and the battery tray 2 is maintained within a specific range. The subsequent pressurizing processes are similar to the first embodiment mentioned above and will not be described in detail.

As shown in FIG. 2, FIG. 3, and FIG. 4, in some embodiments, a pair of spacing maintenance devices 3 is arranged on two sides of the battery tray 2. In response to that the battery tray 2 moves to a pressurizing position, the pair of spacing maintenance devices 3 move close to the battery tray 2. In some embodiments, the pair of spacing maintenance devices 3 are configured to maintain the distance between the two adjacent partition plates 23 on the battery tray 2 and supply power for the batteries (not shown) to perform the formation process.

In some embodiments, the thrust generator 111 may be a screw jack reducer, a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, or a linear motor, while the present disclosure is not limited thereto. In some embodiments, the pressurizing head 114 has a plurality of magnets 4 (as shown in FIG. 5), and the pressure-bearing plate 22 of the battery tray 2 is made of magnetic materials. In some embodiments, in response to that the formation process of the batteries is finished, the pressurizing head 114 moves away from the battery tray 2. At this moment, the pressurizing head 114 can attach the pressure-bearing plate 22 through the plurality of magnets 4 to make the battery tray 2 close to the mounting base 110, and the fixing plate 200 of the battery tray 2 can be detached from the pair of locking arms 120 to make the pair of locking arms 120 smoothly move to the initial position resiliently.

In some embodiments, the controller 13 may be a hardware element which has a control function, such as but not limited to a central processing unit (CPU), a microprocessor, a digital signal processor (DSP), a complex programmable logic device (CPLD), a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), or a microcontroller unit (MCU). In addition, the controller 13 may be any single or multiple processor computing devices/systems that execute computer readable instructions, such as but not limited to a workstation, a laptop computer, a client terminal, a server, a distributed computing system, a handheld device, or any other computing systems/devices. In a basic configuration, the controller 13 may include at least one processor and system memory.

In some embodiments, each of the pair of actuators 121 may be a pneumatic cylinder, an electric cylinder, or a linear motor; the first sliding member 122 and the second sliding member 123 may respectively be a guide device which has a sliding function, such as but not limited to a linear sliding rail, a ball screw, a linear bearing, an air levitation system, or a magnetic levitation system.

Although the present disclosure has been described in considerable detail with reference to certain preferred embodiments thereof, the disclosure is not for limiting the scope of the invention. Persons having ordinary skill in the art may make various modifications and changes without departing from the scope and spirit of the disclosure. Therefore, the scope of the appended claims should not be limited to the description of the preferred embodiments described above.
