Description

Technical Field

[0001] This invention relates to the field of lithium battery processing equipment technology, and in particular to a lithium battery pack forming system. Background Technology

[0002] Flexible lithium battery packs are compressed into multiple continuous units during processing, and then cut into individual battery packs (i.e., individual lithium battery packs, hereinafter referred to as battery packs). During the cutting process, a cutting mechanism provided by the applicant's prior utility model application, publication number CN223506299U, can be used. This utility model specifically relates to a lithium battery cutting structure, which includes a pair of uprights and a crossbeam fixedly connected to the two uprights. A telescopic actuator is mounted on the crossbeam. A cutter, driven by the telescopic actuator, is located below the crossbeam between the two uprights and moves up and down. A baffle is also fixedly connected between the two uprights and below the cutter. The cutter has a blade that abuts against the baffle. A flexible stop strip is also connected to the cutter, and the flexible stop strip has a free end extending below the top surface of the stop strip. This utility model solves the problem in the prior art where the cut lithium battery body may become increasingly unstable due to its forward bounce. However, the applicant discovered during subsequent use that the battery pack might fall downwards before it was cut, causing the cutting point to rise upwards, which could lead to the battery pack behind it being accidentally touched by the cutter, causing a hazard. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a lithium battery pack forming system that solves the problem that the battery pack may be accidentally touched by the cutter during cutting, which may lead to danger.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A lithium battery pack forming system includes a cutting mechanism. The cutting mechanism includes a mounting frame formed by a mounting beam and a pair of columns fixed to both ends of the mounting beam. The two columns extend downward and are equipped with cutters located below the mounting beam, which are reciprocated vertically between each other. The lower end of the cutter is a cutting edge, and a flexible sheet is connected to the cutter. The flexible sheet has a downward-facing free end. A support beam is fixed between the lower ends of the two columns. A guide plate extending outward from the mounting frame is fixed to the support beam. An airbag is connected to the guide plate. An air inlet pipe for introducing gas into the airbag and an air outlet pipe for discharging gas are fixed to the guide plate. Initially, the airbag has a top surface that is flush with or lower than the top surface of the cutting edge when it is at its lowest position, and the flexible sheet and the airbag are both located on the same side of the cutting edge. In this solution, the airbag provides upward support for the battery pack, and the flexible sheet ensures that the battery pack remains stable during the cutting process. This prevents the cutter from accidentally contacting the battery pack during operation. After cutting, the airbag inflates and lifts one end of the battery pack, allowing the battery pack to be discharged more smoothly through the airbag and the guide plate. This ensures smooth discharge while maintaining cutting safety, solving the problem in existing technologies where the battery pack may be accidentally touched by the cutter during cutting, leading to potential danger.

[0006] Furthermore, the guide plate is inclined and its lower end is away from the support beam, and the airbag body has an inclined surface that is away from the support beam, with the lower end of the inclined surface extending in the same direction as the lower end of the guide plate.

[0007] Furthermore, an inclined plate is fixed between the lower end of the airbag and the lower end of the guide plate, with both ends of the inclined plate flush with the airbag and the guide plate, respectively.

[0008] Furthermore, a top strip is fixed inside the airbag, close to its top surface and located between the top surface and the blade, and the top strip is parallel to the support beam.

[0009] Furthermore, the support beam is provided with an installation step located below the blade, and one end of the guide plate is fixed to the installation step, while the other end extends outside the mounting frame.

[0010] Furthermore, an installation strip is installed below the installation beam, which moves up and down. The installation strip is fixed with a moving rod, which moves upward and passes through the installation beam. The upper end of the cutter is connected to the installation strip.

[0011] Furthermore, the cutter includes a mounting plate connected to the mounting strip and a blade connected to the mounting plate, the lower end of the blade being the cutting edge, and a flexible sheet connected to the mounting plate.

[0012] Furthermore, an installation notch is provided on the side of the lower end of the mounting plate opposite to the guide plate, the upper end of the blade is connected to the installation notch, and one end of the flexible sheet is connected to the other side of the mounting plate opposite to the installation notch.

[0013] Furthermore, the bottom surface of the mounting strip is recessed with a mounting groove, and the upper end of the mounting plate is connected to the mounting groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By incorporating airbags on the guide plate, the airbags provide upward support for the battery pack. Combined with a flexible sheet, this ensures the battery pack remains stable during the cutting process, preventing accidental contact between the cutter and the battery pack. After cutting, the airbags inflate and lift one end of the battery pack, allowing for smoother discharge through the airbags and guide plate. This ensures both smooth discharge and safe cutting, solving the problem of potential danger caused by accidental contact between the battery pack and the cutter in existing technologies.

Detailed Implementation

[0021] The present invention will be further described in detail below through specific embodiments:

[0022] like Figure 1-3 As shown, this solution provides a lithium battery pack molding system.

[0023] It includes a cutting mechanism, with a pressing mechanism in front of the cutting mechanism. After pressing, the battery pack 1 is conveyed to the cutting mechanism for cutting, thereby obtaining individual battery packs 1. Specifically, the cutting mechanism includes a mounting frame formed by a mounting beam 2 and a pair of uprights 3 fixed to both ends of the mounting beam 2. The mounting frame itself can be a U-shaped structure, similar to that in the prior art, that is, the two uprights 3 extend downwards, and a support beam 4 is fixed between their lower ends. The support beam 4 and the mounting frame form a frame structure, and a cutter 5 is reciprocating up and down inside the frame structure. The lower end of the cutter 5 is the blade. 18. A flexible sheet 6 (which can be made of a rubber material with good elasticity) is also connected to the cutter 5. The flexible sheet 6 has a downward-facing free end and is located behind the mounting frame (the pressing mechanism is in front of the mounting frame). The support beam 4 is also fixed with a guide plate 7 extending outward from the mounting frame and located below the flexible sheet 6. An air bladder 8 is also connected to the guide plate 7. That is, the air bladder 8 and the flexible sheet 6 are located on the same side of the cutter 5. Furthermore, an air inlet pipe 9 for introducing gas into the air bladder 8 and an air outlet pipe 10 for discharging gas are also fixed to the guide plate 7. Solenoid valves are installed on the air pipe 10, and the air inlet pipe 9 is also connected to an air pump. When the air pump is running, the air inlet pipe 9 opens to supply gas into the airbag 8, at which time the air outlet pipe 10 closes and the airbag 8 inflates. Conversely, when the air outlet pipe 10 opens, the air inlet pipe 9 closes and the air outlet pipe 10 opens, and the airbag 8 returns to its initial state. Furthermore, the airbag 8 initially has a top surface that is flush with or lower than the top surface of the blade 18 when it is at its lowest position, and the flexible sheet 6 and the airbag 8 are both located on the same side of the blade 18. In this way, the pressed battery pack 1 can smoothly pass under the cutter 5 so that... Battery packs 1 are located on both sides of the cutter 5, and the cutting position 11 is located directly below the cutter 5. In this solution, the airbag 8 provides upward support for the battery pack 1, and the flexible sheet 6 keeps the battery pack 1 stable during the cutting process. This means that the cutter 5 will not accidentally touch the battery pack 1 during operation. After cutting, the airbag 8 inflates and lifts one end of the battery pack 1, so that the battery pack 1 can be discharged more smoothly through the airbag 8 and the guide plate 7. This ensures smooth discharge and safe cutting, and solves the problem in the prior art that the battery pack 1 may be accidentally touched by the cutter 5 during cutting, which may lead to danger.

[0024] In further proposals, such as Figure 1-3As shown, the guide plate 7 is inclined and its lower end faces away from the support beam 4. The airbag 8 has an inclined surface facing away from the support beam 4, and the lower end of the inclined surface extends in the same direction as the lower end of the guide plate 7. Before cutting, most of the battery pack 1 passes over the top surface, but the battery pack 1 on the other side is not broken (i.e., not cut). Therefore, the battery pack 1 can be relatively stable. At the same time, the flexible sheet 6 is bent and presses on the battery pack 1, which ensures stability during the cutting process and prevents the battery pack 1 from flying upwards and detaching after cutting. During or after cutting, the air pump runs, causing the airbag 8 to inflate, so that the side of the battery pack 1 facing the cutter 5 can be cut more smoothly. The flexible sheet 6 is always pressed against the battery pack 1, ensuring that the battery pack 1 will not fly out. When the cutter 5 returns upward, the flexible sheet 6 also moves upward, releasing the pressure on the battery pack 1. The battery pack 1 smoothly moves diagonally downward through the inclined surface of the airbag body 8 and finally leaves through the guide plate 7. Furthermore, an inclined plate 12 is fixed between the lower end of the airbag body 8 and the lower end of the guide plate 7. The two ends of the inclined plate 12 are flush with the airbag body 8 and the guide plate 7, respectively. The airbag body 8 can fall back when the cutter 5 returns upward, or it can fall back after the battery pack 1 reaches the inclined plate 12.

[0025] In the detailed plan, such as Figure 1-3 As shown, a top strip 13 is fixed inside the airbag body 8, close to its top surface and located between the top surface and the cutting edge 18. The top strip 13 is parallel to the support beam 4. The top strip 13 and the inner wall of the airbag body 8 can be integrally formed. The top strip 13 has a greater thickness than the inner wall of other parts of the airbag body 8, so the top strip 13 is harder. The top strip 13 is specifically located on the inner top surface of the airbag body 8, that is, when the airbag body 8 inflates, the top strip 13 also moves upward, thereby assisting the cut battery pack 1 to tilt upward. In a further embodiment, the support beam 4 is provided with an installation step located below the cutting edge 18. One end of the guide plate 7 is fixed to the installation step, and the other end extends outside the mounting frame. The airbag body 8 and the cutter 5 are offset.

[0026] like Figure 1-2 As shown, in a further embodiment, an installation strip 14 is installed below the mounting beam 2, which moves up and down. The two ends of the installation strip 14 can slide in contact with the two columns 3 or be separated from each other. The installation strip 14 is fixed with a moving rod 15, which moves upward and passes through the mounting beam 2. The upper end of the moving rod 15 is used to connect with the driver that drives it up and down, which is the cutting power source, such as a cylinder. More specifically, the upper end of the cutter 5 is connected to the installation strip 14. In this way, the up and down movement of the installation strip 14 drives the cutter 5 up and down, thus achieving the cutting smoothly.

[0027] like Figure 1-3As shown, the cutter 5 includes a mounting plate 16 connected to the mounting strip 14 and a blade 17 connected to the mounting plate 16. The lower end of the blade 17 is a cutting edge 18. The flexible sheet 6 is connected to the mounting plate 16. More specifically, the lower end of the mounting plate 16 has a mounting notch on the side opposite to the guide plate 7. The upper end of the blade 17 is connected to the mounting notch, and one end of the flexible sheet 6 is connected to the other side of the mounting plate 16 opposite to the mounting notch. The blade 17, the mounting plate 16, and the flexible sheet 6 can be connected using conventional fasteners. Similarly, the mounting... The bottom surface of the strip 14 is recessed and has a mounting groove. The upper end of the mounting plate 16 is connected to the mounting groove. The mounting plate 16 and the mounting strip 14 are also connected by conventional fasteners to facilitate subsequent replacement and maintenance. This also separates the blade 17 and the flexible sheet 6. More specifically, before the battery pack 1 passes under the cutter 5, the free end of the flexible sheet 6 is pressed on the airbag body 8, and at this time the blade 18 is at its highest position. The movement of the battery pack 1 can push open the flexible sheet 6 so that the flexible sheet 6 presses on the battery pack 1.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
