Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] See Figures 1 to 11 As shown, one embodiment of this application discloses a sheet-making hot-pressing composite device, including a first hot-pressing mechanism 310, a conveying mechanism 200, and a first unwinding mechanism 410.

[0040] Specifically, the first hot pressing mechanism 310 has a first hot pressing chamber; the conveying mechanism 200 is used to convey the sheet material into the first hot pressing chamber along the conveying axis, wherein the conveying axis is flush with the hot pressing plane of the first hot pressing chamber; the first unwinding mechanism 410 is disposed on the opposite side of the first hot pressing mechanism 310, and the first unwinding mechanism 410 is used to convey the strip material into the first hot pressing chamber along the conveying axis.

[0041] In the sheet-making hot-pressing composite device provided in this application embodiment, the conveying mechanism 200 is used to convey the sheet to the first hot-pressing chamber along the conveying axis. The first hot-pressing mechanism 310 has a first hot-pressing chamber. The hot-pressing plane of the first hot-pressing chamber is located on the same plane as the conveying coaxial line. The first unwinding mechanism 410 conveys the strip to the first hot-pressing chamber along the conveying axis. That is to say, during the hot-pressing process, the reference for the composite of the sheet and the strip can be located on the same plane, which can avoid displacement during the composite process of the sheet and the strip and help to ensure the composite effect of the sheet and the strip.

[0042] In one embodiment, see Figure 1 The sheet-making hot-pressing composite device includes a second hot-pressing mechanism 320. The first hot-pressing mechanism 310 and the second hot-pressing mechanism 320 are arranged at intervals along the conveying axis. The second hot-pressing mechanism 320 is located on the side of the conveying axis away from the first hot-pressing mechanism 310. The second hot-pressing mechanism 320 has a second hot-pressing cavity, and the hot-pressing plane of the second hot-pressing cavity is flush with the conveying axis. The sheet-making hot-pressing composite device also includes a second unwinding mechanism 420. The second unwinding mechanism 420 is arranged on the opposite side of the second hot-pressing mechanism 320, and the second unwinding mechanism 420 is used to convey another material strip along the conveying axis.

[0043] In the above embodiments, the first and second hot-pressing chambers are spaced apart along the conveying axis, and the hot-pressing planes of both chambers are flush with the conveying axis. This ensures that the reference point for the sheet material during bonding in both chambers is on the plane of the conveying axis, preventing displacement due to different reference points and thus guaranteeing the bonding effect. Simultaneously, the first and second hot-pressing mechanisms 310 and 320 are respectively positioned on both sides of the conveying axis, enabling bonding of both the upper and lower surfaces of the sheet material with the conveying axis, achieving double-sided bonding. Compared to bonding the sheet and conveying axis at two different stations, this embodiment effectively improves bonding efficiency. Furthermore, the space utilization is improved by the space-time arrangement of the first and second hot-pressing mechanisms 310 and 320, with corresponding first and second unwinding mechanisms 410 and 420, effectively reducing the equipment's footprint.

[0044] In one embodiment, see Figure 3 and Figure 4The first hot pressing mechanism 310 includes a first upper pressure plate 311, a first lower pressure plate 312, a first hot pressing plate 313, a first telescopic component 314, and a first hot pressing drive component 315. The first upper pressure plate 311 and the first lower pressure plate 312 are connected by the first telescopic component 314. The first hot pressing drive component 315 is used to drive the first upper pressure plate 311 and the first lower pressure plate 312 to move closer or further apart from each other with the conveying axis as the central axis. In this way, it can be ensured that the hot pressing plane of the first hot pressing mechanism 310 is always located on the same plane as the conveying axis. In this embodiment, the first unwinding mechanism 410 conveys the material strip to the first hot pressing chamber along the conveying axis. That is, the material strip and the material sheet are both located on the hot pressing plane of the first hot pressing mechanism 310 during hot pressing. In this way, it can avoid the displacement difference between the material sheet and the material strip during the hot pressing process, which would lead to a poor composite alignment and help ensure the composite effect of the material sheet and the material strip.

[0045] In one embodiment, see Figure 1 and Figure 7 The second hot pressing mechanism 320 includes a second upper pressure plate 321, a second lower pressure plate 322, and a second hot pressing drive assembly 324. The second hot pressing drive assembly 324 is used to drive the second upper pressure plate 321 and the second lower pressure plate 322 to move closer or further away from each other with the conveying axis as the center. In this way, the hot pressing plane of the second hot pressing mechanism 320 and the conveying axis are located on the same plane.

[0046] In the above embodiment, the second unwinding mechanism 420 conveys the material strip to the second hot pressing chamber along the conveying axis. That is, the material strip and the material sheet are both located on the hot pressing plane of the second hot pressing mechanism 320 during hot pressing. In this way, the displacement difference between the material sheet and the material strip during the hot pressing process can be avoided, which would lead to a poor composite alignment and help ensure the composite effect of the material sheet and the material strip.

[0047] In one embodiment, see Figure 1 and Figure 2 The sheet-forming hot-pressing laminating device also includes a feeding mechanism 100, which comprises a support 110, a robotic arm 120, and a drive unit 130. The support 110 is disposed on one side of the conveying mechanism 200, and the robotic arm 120 is movably mounted on the support 110. The robotic arm 120 is used to pick up the sheet, and the drive unit 130 is used to drive the robotic arm 120 to move along a second direction. The second direction is perpendicular to the first direction, and the first direction is parallel to the conveying axis. By transferring the sheet to the conveying mechanism 200 via the robotic arm 120, the relative position of the sheet on the conveying plane of the conveying mechanism 200 remains consistent, ensuring the alignment of the sheet and the conveyor belt in the second direction, thereby guaranteeing the laminating effect of the sheet and the conveyor belt.

[0048] It should be pointed out that, Figure 1 As shown, the X direction is the first direction, the Y direction is the second direction, and the plane formed by the X and Y directions is a horizontal plane.

[0049] In one embodiment, see Figure 2 The robotic arm 120 includes a loading and lifting drive and an adsorption assembly 121. The adsorption assembly 121 is connected to the output end of the loading and lifting drive and is used to adsorb material sheets. By using the adsorption assembly 121 to adsorb the material sheets at the loading station, and then driving the loading and lifting drive to move laterally as a whole, after moving into position, the loading and lifting drive drives the adsorption assembly 121 to descend, so that the material sheets can be placed on the conveying mechanism 200.

[0050] In this embodiment, the support 110 is a gantry frame, which spans above the conveying mechanism 200 to facilitate the transfer of the sheet material onto the conveying mechanism 200. Compared to the cantilevered support 110, the gantry frame in this embodiment has higher structural strength, avoids the displacement deviation present in cantilever structures, and helps to ensure the alignment of the sheet material and the conveyor belt in the second direction, thereby ensuring the composite accuracy of the sheet material and the conveyor belt.

[0051] In one embodiment, see Figure 3 and Figure 4 The conveying mechanism 200 includes a conveyor plate assembly 210 and a conveying drive assembly 220. The conveying drive assembly 220 drives the conveyor plate assembly 210 to move along the conveying axis to feed the sheet into the first hot pressing chamber. The support plane of the conveyor plate assembly 210 is located on the same plane as the conveying axis. It is worth noting that the conveying axis is parallel to the first direction.

[0052] In one possible implementation, see Figure 3 and Figure 4 The conveyor plate assembly 210 includes a first conveyor plate 211, the support surface of which is located on the same plane as the conveying axis. When the sheet and the strip are combined in the first hot pressing chamber, the conveying drive assembly 220 drives the first conveyor plate 211, on which the sheet is placed, to move into the first hot pressing chamber. The first hot pressing mechanism 310 then actuates, causing the strip of the first unwinding mechanism 410 to combine with the sheet located on the first conveyor plate 211.

[0053] In one possible implementation, Figure 5 and Figure 6 The conveyor plate assembly 210 includes a first conveyor plate 211 and a second conveyor plate 212, which are spaced apart along the conveying axis. The conveying drive assembly 220 is used to drive the first conveyor plate 211 and the second conveyor plate 212 to move along the conveying axis, respectively. It is worth noting that the conveying drive assembly 220 includes a lifting guide rail 221, and the first conveyor plate 211 and the second conveyor plate 212 are slidably connected to different lifting guide rails 221 via mounting brackets. The conveying drive assembly 220 is also used to drive the first conveyor plate 211 and the second conveyor plate 212 to rise and fall, respectively.

[0054] In practical applications, the lifting guide rail 221 and mounting bracket that cooperate with the first conveyor plate 211 are located on one side of the conveying drive assembly 220, while the lifting guide rail 221 and mounting bracket that cooperate with the second conveyor plate 212 are located on the other side of the conveying drive assembly 220. When the first conveyor plate 211 needs to move to the other end of the second conveyor plate 212 along the conveying axis, the conveying drive assembly 220 drives the first conveyor plate 211 to rise, causing the first conveyor plate 211 and the second conveyor plate 212 to be misaligned. Then, the second conveyor plate 212 is driven to move along the conveying axis, and the first conveyor plate 211 is driven to move in the opposite direction of the conveying axis. This allows the second conveyor plate 212 to move into the first hot pressing chamber for compounding, while the first conveyor plate 211 moves out of the first hot pressing chamber for loading. This improves loading and compounding efficiency.

[0055] In one embodiment, see Figure 8 and Figure 9 The first unwinding mechanism 410 includes a first support roller 411, a first unwinding drive assembly 412, and a first unwinding assembly 413. The first support roller 411 is disposed at the feed end of the first hot pressing mechanism 310 and is tangential to the conveying axis. The first unwinding drive assembly 412 drives the first unwinding assembly 413 to unwind. The tangential arrangement of the first support roller 411 to the conveying axis allows the material strip from the first unwinding assembly 413 to be conveyed along the conveying axis into the first hot pressing chamber of the first hot pressing mechanism 310, reducing displacement differences between the material strip and the sheet during hot pressing and ensuring the hot pressing effect.

[0056] It is worth understanding that one end of the material strip of the first unwinding mechanism 410 passes through the first hot pressing chamber and the second hot pressing chamber and is connected to the conveying roller or the winding mechanism (not shown in the figure) so that the material strip can be conveyed forward along the conveying axis.

[0057] In one embodiment, please continue to refer to Figure 8 and Figure 9 The first unwinding mechanism 410 includes a first adjusting drive 414, which is used to adjust the relative position of the first unwinding mechanism 410 along a second direction, wherein the second direction is perpendicular to the first direction in the same horizontal plane. By adjusting the relative position of the first unwinding mechanism 410 in the second direction through the first adjusting drive 414, the material strip and the sheet of the first unwinding mechanism 410 can be aligned in the second direction, which helps to ensure the composite accuracy.

[0058] In one embodiment, see Figure 10 and Figure 11As shown, the second unwinding mechanism 420 includes a second unwinding assembly 421, a second unwinding drive assembly 422, and a second adjusting drive member 423. The second unwinding assembly 421 is used for unwinding, the second unwinding drive assembly 422 is used to drive the second unwinding assembly 421 to rotate and unwind, and the second adjusting drive member 423 is used to drive the second unwinding mechanism 420 to move and adjust its position along a second direction, wherein the second direction is perpendicular to the first direction in the same horizontal plane. By adjusting the relative position of the second unwinding mechanism 420 in the second direction through the second adjusting drive member 423, the material strip and the material sheet of the second unwinding mechanism 420 can be aligned in the second direction, which helps to ensure the composite accuracy of the material sheet and the material strip.

[0059] In one embodiment, see Figure 10 and Figure 11 As shown, the second unwinding mechanism 420 includes a second support roller 424, a second pressure roller 425, and a second pressure roller drive member 426. The second support roller 424 is tangentially arranged to the conveying axis, and the second pressure roller 425 is arranged opposite to the first support roller 411. The second pressure roller drive member 426 is used to drive the second pressure roller 425 to move closer to or away from the second support roller 424. The tangential arrangement of the second support roller 424 to the conveying axis allows the material strip of the second unwinding assembly 421 to be conveyed along the conveying axis to the second hot pressing chamber of the second hot pressing mechanism 320, which can reduce the displacement difference between the material strip and the sheet during the hot pressing process and help ensure the hot pressing effect.

[0060] It is worth mentioning that, in one embodiment, the tape is a single-layer diaphragm. In other embodiments, the tape can be a composite tape including electrodes and a diaphragm.
