DETAILED DESCRIPTION

[0024] 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.

[0025] like Figure 1-3 As shown, a sheet folding and welding platform in one embodiment of the present invention includes a sheet material taking-and-putting assembly 1, a sheet material folding assembly 2, a welding assembly 3, a material storage assembly 4 and a conveying assembly 5. The sheet material taking-and-putting assembly 1 is used for taking and putting sheets. The sheet material folding assembly 2 is arranged downstream of the sheet material taking-and-putting assembly 1 for folding the edge of the sheet. The welding assembly 3 is arranged above the sheet material folding assembly 2 for welding the folded sheet. The material storage assembly 4 is arranged downstream of the sheet material folding assembly 2 for storing the welded sheet. The conveying assembly 5 is arranged downstream of the material storage assembly 4 for conveying the sheet stored in the material storage assembly 4 to an external storage member.

[0026] In the above embodiment, the sheet material taking and discharging assembly 1 conveys the sheet material to the sheet material folding assembly 2. After the sheet material folding assembly 2 folds the sheet material, the welding assembly 3 welds the folded portion of the sheet material to improve the tensile strength of the sheet material. After welding, the sheet material taking and discharging assembly moves the sheet material from the sheet material folding assembly 2 to the material storage assembly 4. After the material storage assembly 4 stores a certain number of sheets, the conveying assembly 5 transports the sheets to the external storage member.

[0027] With such arrangement, the sheet folding and welding platform can realize fully automatic folding, welding and conveying of the sheet, thereby improving the stability of welding quality and the tearing strength of the sheet.

[0028] In one embodiment, if Figure 1As shown, the sheet material taking and placing assembly 1 includes a material tray 11, a guide rail frame 12 and a suction cup frame 13. The material tray 11 is used to store sheets. For example, multiple sheets can be stacked on the material tray 11. Preferably, the material tray 11 is provided with a plurality of vertically extending positioning posts 111 along its circumference. The plurality of positioning posts 111 are arranged on the material tray 11 roughly along the contour of the sheet, so as to prevent the sheet from being offset on the material tray 11, so that the sheet is always within the set position range, and will not affect the suction of the sheet by the suction cup frame 13.

[0029] The guide rail frame 12 is arranged above the material tray 11, the sheet folding assembly 2 and the material storage assembly 4. A plurality of suction cups 131 are arranged on the suction cup frame 13 for sucking the sheet. The suction cup frame 13 can move up and down to get closer to or away from the sheet. The suction cup frame 13 can also move along the guide rail to realize the sheet transportation between the material tray 11, the sheet folding assembly 2 and the material storage assembly 4. Preferably, two suction cup frames 13 can be provided. For example, one suction cup frame 13 is arranged above the material tray 11, and the other suction cup frame 13 is arranged above the sheet folding assembly 2. Furthermore, the two suction cup frames 13 can move synchronously and in the same direction along the guide rail frame 12 to realize the simultaneous taking and placing of the sheet.

[0030] Specifically, if Figure 4 As shown, the suction cup frame 13 above the material tray 11 is the first suction cup frame 132, and the suction cup frame 13 above the sheet folding assembly 2 is the second suction cup frame 133. In the initial state, the first suction cup frame 132 approaches the material tray 11 and absorbs the sheet on the material tray 11. At the same time, the second suction cup frame 133 approaches the sheet folding assembly 2. Since there is no sheet in the sheet folding assembly 2, the second suction cup frame 133 does not absorb anything. Then, the first suction cup frame 132 moves along the guide frame 12 to the sheet folding assembly 2 and places the sheet on the sheet folding assembly 2 and returns to the top of the material tray 11; the second suction cup frame 133 moves synchronously to the material storage assembly 4 and returns to the top of the sheet folding assembly 2.

[0031] At this time, a sheet is placed at the sheet folding component 2, and a plurality of sheets to be folded are placed on the material tray 11. After the sheet at the sheet folding component 2 is folded and welded, the second suction cup frame 133 sucks the sheet at the sheet folding component 2; synchronously, the first suction cup frame 132 sucks the sheet on the material tray 11. Then, the second suction cup frame 133 moves to the top of the material storage component 4 and releases the welded sheet to the material storage component 4, and the first suction cup frame 132 moves to the top of the sheet folding component 2 and releases the sucked sheet to the sheet folding component 2; thus, the first suction cup frame 132 and the second suction cup frame 133 work together to achieve synchronous suction and release of the sheet, thereby improving the working efficiency of the sheet folding and welding platform.

[0032] In one embodiment, if Figure 3As shown, the sheet folding assembly 2 includes: a folding table 21, a pressure bar 22 and a folding bar 23. The folding table 21 is arranged below the welding assembly 3. The pressure bar 22 is arranged on both sides of the folding table 21. The pressure bar 22 can move horizontally to the top of the folding table 21 and be pressed on the folding table 21, so as to press the sheet on the upper surface of the folding table 21. The folding bar 23 is closely arranged on both sides of the folding table 21 and is located below the pressure bar 22; the folding bar 23 can move upward along the side wall of the folding table 21 and horizontally along the upper surface of the folding table 21, so as to fold the sheet.

[0033] The specific working method of the sheet folding component 2 is as follows: when the sheet is placed on the folding table 21, parts of the two ends of the sheet extend out of the folding table 21. The pressure strip 22 moves from both sides of the folding table 21 to the top of the folding table 21, and the outer edge of the pressure strip 22 is aligned with the outer edge of the folding table 21 and moves downward to be pressed on the sheet. Then, the folding strip 23 moves upward close to the side wall of the folding table 21, and the part of the sheet extending out of the folding table 21 is folded upward. After the lower surface of the folding strip 23 is slightly higher than the upper surface of the folding table 21, the folding strip 23 moves horizontally toward the position of the pressure strip 22 so that the sheet continues to fold in the direction close to the pressure strip 22. After the sheet is folded to a certain angle, the pressure strip 22 retreats in the direction away from the folding strip 23, and the folding strip 23 continues to move and be pressed to the upper surface of the folding table 21, completing the folding of the sheet. After the folding is completed, the welding component 3 welds the folded part.

[0034] Furthermore, the folding strip 23 is provided with a plurality of avoidance holes 231 spaced apart along its length direction. The welding head 33 of the welding assembly 3 can be inserted into the avoidance hole 231 to weld the folded sheet. With such arrangement, during welding, the folding strip 23 does not need to be moved, and the folded part of the sheet can be prevented from warping, which will not affect the welding.

[0035] In one embodiment, the welding assembly 3 includes: a support frame 31, a welding fitting portion 32 and a welding head 33. The support frame 31 is arranged on one side of the sheet folding assembly 2. The welding fitting portion 32 is arranged on the support frame 31. The welding head 33 is arranged at the bottom of the welding fitting portion 32 and can move up and down relative to the welding fitting portion 32.

[0036] Preferably, the welding fitting portion 32 is slidably disposed on the support frame 31 to adjust the height of the welding head 33 relative to the sheet folding assembly 2 to adapt to different sheet folding requirements and avoid interference with the folding process.

[0037] In the present invention, the material storage component 4 and the conveying component 5 can adopt existing structures. For example, the material storage component 4 can be a tray or a similar structure. The conveying component 5 can be a roller conveyor or a similar structure.

[0038] In one embodiment, if Figure 5As shown, the storage component 4 includes two limiting walls 41 and a driving cylinder 42. The two limiting walls 41 are slidably arranged on the surface of the conveying component 5. The two limiting walls 41 are arranged relative to each other to form a storage space for placing sheets. Each limiting wall 41 can be composed of two parts, and the two parts are connected by a connecting piece. The driving cylinder 42 is connected to the two limiting walls 41, and is used to drive the two limiting walls 41 to move closer or farther away. Specifically, the two limiting walls 41 can be close to each other to form a rectangular storage space. The sheets are stacked in the storage space in sequence. When the sheets are stacked to a certain number, the two limiting walls 41 are driven by the driving cylinder 42 to move away from each other, and cannot form a restrictive effect on the sheets. The conveying component 5 drives the sheets to move and transports the sheets to the external storage member.

[0039] In one embodiment, the conveying assembly 5 includes a carrier 51 and a conveyor belt 52. Rollers 511 are provided at both ends of the carrier 51. The conveyor belt 52 is connected to the rollers 511 and can move under the drive of the rollers 511. The limiting wall 41 of the storage assembly 4 is provided on the surface of the conveyor belt 52 and can move in a direction perpendicular to the conveying direction of the conveyor belt 52 under the drive of the driving cylinder 42. When the limiting walls 41 are away from each other and cannot form a limiting effect on the stacked sheets, the conveyor belt 52 starts to work and drives the sheets to move.

[0040] The sheet folding and welding platform of the present invention can fold and weld a variety of sheet materials, for example, insulating films used in new energy vehicle batteries or other materials with the same processing requirements.

[0041] It should be noted that the sheet folding and welding platform is also provided with a variety of cylinders and sensors to assist in the movement and operation of the above-mentioned accessories. The configuration thereof is a conventional technical means in this field and will not be described in detail here.

[0042] In summary, the sheet folding and welding platform is provided with a sheet material taking and placing component 1 to realize automatic absorption and release of the sheet. The sheet folding component 2 and the welding component 3 cooperate to realize automatic folding and welding of the sheet. The storage component 4 cooperates with the conveying component 5 to realize automatic storage and conveying of the sheet. Therefore, the sheet folding and welding platform can realize automatic folding, welding and conveying of the sheet. Through automated production, no manual operation is required, thereby improving the stability of the sheet folding and welding quality and improving the tearing strength of the sheet.
