Description

Technical Field

[0001] The invention belongs to the technical field of sheet material processing, and in particular relates to a sheet material folding platform. Background Art

[0002] With the development of new energy vehicles, the importance of insulation filling and tear strength of new energy battery products is increasingly valued by battery manufacturers. In the design of insulation applications, thickening the insulation film can enhance its puncture resistance and prevent internal short circuits caused by factors such as uneven electrode surface and burrs on the electrode edges during manufacturing or use of the battery. At the same time, thicker insulation films can remain more stable at high temperatures, preventing thermal runaway of the battery due to overcharging or overheating, thereby improving the overall safety and stability of the battery. Traditional insulation films are generally produced by manual folding and manual welding methods, which are inefficient, and manual folding is prone to deviations, resulting in unstable welding quality, which can easily cause insufficient tear strength of the insulation film, affecting the service life and safety of the battery. In addition to insulation films, other sheets also face similar problems in processes that require folding.

[0003] Therefore, it is of great practical significance to develop a folding device with a high degree of automation and the ability to improve the stability of folding quality.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] like Figure 1-5 As shown, a sheet folding platform in one embodiment of the present invention includes a frame 1, a rectangular folding table 2, two pressure strips 3 and two folding strips 4. The rectangular folding table 2 is arranged on the frame 1 for placing a sheet 8. The two pressure strips 3 are respectively arranged on both sides of the rectangular folding table 2 and are higher than the rectangular folding table 2. The pressure strip 3 can be horizontally moved to the top of the rectangular folding table 2 and descended to be pressed on the surface of the rectangular folding table 2 for pressing the sheet 8. The two folding strips 4 are also arranged on the said two sides of the rectangular folding table 2 and arranged below the pressure strip 3. The folding strip 4 is tightly fitted with the side wall of the rectangular folding table 2 and the upper surface of the folding strip 4 is flush with the upper surface of the rectangular folding table 2. The folding strip 4 can move vertically upward to be higher than the rectangular folding table 2 and horizontally to the top of the rectangular folding table 2, and then descend and be pressed on the surface of the rectangular folding table 2 for bending the edge of the sheet 8.

[0027] In the above embodiment, after the sheet 8 is placed on the rectangular folding table 2, parts of both ends of the sheet 8 extend out of the rectangular folding table 2. The pressing strip 3 moves from both sides of the rectangular folding table 2 to the top of the rectangular folding table 2, and the edge of the pressing strip 3 is aligned with the edge of the rectangular folding table 2 and moves downward to be pressed on the sheet 8. Then, the folding strip 4 moves upward close to the side wall of the rectangular folding table 2, and folds the part of the sheet 8 extending out of the rectangular folding table 2 upward. After the lower surface of the folding strip 4 is higher than the upper surface of the rectangular folding table 2, the folding strip 4 moves horizontally toward the position of the pressing strip 3 so that the sheet 8 continues to fold in the direction close to the pressing strip 3. After the sheet 8 is folded to a certain angle, the pressing strip 3 retreats in the direction away from the folding strip 4, and the folding strip 4 continues to move horizontally until the edge of the sheet 8 is folded nearly 180°, and then the folding strip 4 is pressed downward to the upper surface of the rectangular folding table 2 to complete the folding of the sheet 8.

[0028] The sheet folding platform can realize automatic folding of the sheet 8 by setting the pressing strip 3 and the folding strip 4, thereby ensuring the consistency of the folding of the sheet 8 and avoiding errors caused by manual folding.

[0029] In one embodiment, if Figure 2 and 3As shown, a relief groove 31 is provided on one side of the pressure strip 3. When the pressure strip 3 is pressed onto the rectangular folding table 2, the folding strip 4 can be accommodated in the relief groove 31. Specifically, during the folding process of the sheet 8, the folding strip 4 first moves upward, so that the edge of the sheet 8 is folded upward and the lower surface of the folding strip 4 is higher than the upper surface of the rectangular folding table 2; then, the folding strip 4 moves horizontally to drive the edge of the sheet 8 to continue to bend, until the edge of the sheet 8 is folded close to 180°. Next, the folding strip 4 moves downward into the relief groove 31 and presses the edge of the sheet 8 onto the pressure strip 3, then, the pressure strip 3 retreats backward and disengages from the folding strip 4, and the folding strip 4 moves downward again to completely press the edge of the sheet 8 onto the rectangular folding table 2, waiting for welding. After welding, the folding strip 4 and the pressure strip 3 will return to the initial position and wait for the next folding operation.

[0030] Furthermore, the bottom of the avoidance groove 31 is recessed inward along its length to form a folding bottom wall 311. The length of the folding bottom wall 311 is substantially equal to the length of the folding strip 4, and the folding strip 4 can be pressed on the folding bottom wall 311. Preferably, the thickness of the folding bottom wall 311 is between 0.5 mm and 1 mm. Specifically, during the folding process of the sheet 8, the folding strip 4 folds the edge of the sheet 8 with the edge of the folding bottom wall 311 as the folding line. By controlling the thickness of the folding bottom wall 311, it is possible to avoid the sheet 8 from having extra bends at the folding position. At the same time, since the folding bottom wall 311 is relatively thin, the folding strip 4 will be closer to the surface of the rectangular folding platform 2 when pressed on the folding bottom wall 311, and the sheet 8 is close to being completely folded. When the pressing strip 3 retreats from the folding strip 4 and disengages from the folding strip 4, the change or deviation of the folding position and folding degree of the sheet 8 is smaller. After the folding strip 4 is pressed down, the folded position of the sheet 8 remains almost unchanged, thereby ensuring the consistency between each folding of the sheet 8.

[0031] The lifting and movement of the layering strip 3 and the folding can be realized by cylinder control. Figure 4 and 5 As shown, first transverse cylinders 32 are provided on both sides of the bead 3 on the side walls of the rectangular folding table 2, for driving the bead 3 to move in the horizontal direction. A first longitudinal cylinder 33 is provided below the bead 3, for driving the bead 3 to move up and down. It can be understood that matching components can also be provided between the bead 3 and the cylinder to achieve the connection and working cooperation between the bead 3 and the cylinder. These driving components can be matched with cylinder driving components known in the art, which will not be described in detail herein.

[0032] A matching plate 42 is provided below the folding bar 4. A second transverse cylinder 43 is provided on the matching plate 42 to drive the folding bar 4 to move in the horizontal direction. A second longitudinal cylinder 44 is provided below the matching plate 42 to drive the matching plate 42 and the folding bar 4 to move up and down. It can be understood that a matching component can also be provided between the folding bar 4 and the cylinder to achieve the connection and working coordination between the folding bar 4 and the cylinder.

[0033] Further, a plurality of guide rails 6 are provided on the side wall and the matching plate 42 of the rectangular folding table 2. Guide members 7 are provided on both the folding bar 4 and the pressure bar 3, and the guide members 7 are slidably provided on the guide rails 6. The guide rails 6 cooperate with the guide members 7 to limit the moving direction of the folding bar 4 and the pressure bar 3. It can be understood that the setting direction of the guide rails 6 on the side wall and the matching plate 42 of the rectangular folding table 2 is set according to the moving direction of the folding bar 4 and the pressure bar 3, so as to ensure that the moving direction of the folding bar 4 and the pressure bar 3 does not deviate, thereby ensuring the accuracy and consistency of the folding of the sheet 8.

[0034] In one embodiment, if Figure 3 As shown, a plurality of avoidance through holes 41 are sequentially arranged at intervals along the length direction of the folding strip 4 on one side close to the rectangular folding table 2, for the welding head to extend into and weld the folded sheet 8. The arrangement of the avoidance through holes 41 allows the folding strip 4 to be welded without moving, and can prevent the folded portion of the sheet 8 from warping, which will not affect welding.

[0035] In one embodiment, a plurality of limiting strips 21 are sequentially arranged on the surface of the rectangular folding table 2 on the other two sides of the rectangular folding table 2 in a direction perpendicular to the pressure strips 3. The limiting strips 21 can abut against the edges of the sheet 8 placed on the rectangular folding table 2 that do not need to be folded, thereby ensuring that the position of the sheet 8 placed each time is consistent.

[0036] Furthermore, a positioning column 5 is provided on the surface of the rectangular folding table 2. The positioning column 5 can cooperate with the sheet 8 with an opening to further limit the position of the sheet 8 on the rectangular folding table 2. Preferably, the positioning column 5 is detachably connected to the rectangular folding table 2 so as to adapt to sheets 8 of different specifications. The positioning column 5 is selectively installed according to whether the sheet 8 has an opening.

[0037] In summary, the sheet folding platform of the present invention can realize automatic folding of the sheet 8 by setting the pressure strip 3 and the folding strip 4. The pressure strip 3 is provided with an avoidance groove 31 and a folding bottom, which can cooperate with the folding strip 4 to prevent the sheet 8 from shifting or folding deviation during the folding process and make the folding of the sheet 8 more complete, thereby ensuring the consistency of the folding. The sheet folding platform is provided with a limit strip 21 and a positioning column 5, which can further ensure that the position of the sheet 8 on the rectangular folding platform 2 is always consistent, further improving the consistency of the folding and ensuring the yield rate of automated production. In addition, the folding strip 4 is also provided with an avoidance through hole 41, which avoids the influence of welding on the folding process of the sheet 8, thereby ensuring the consistency of the subsequent welding process.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
