[0002] During the charging and discharging process of electric vehicle batteries, the cells expand and contract. To mitigate this, polypropylene foam cushioning pads are typically bonded between adjacent cells. This foam material is usually manufactured using a cavity foaming process, and suppliers generally provide it in sheet form. To meet the demands of continuous production, the sheet cushioning pads need to be overlapped and rolled into rolls. Currently, the overlapping process relies heavily on manual operation, which can easily lead to inconsistent seam gaps and misalignment of the front and rear sheets. Utility Model Content

[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] To meet the demands of continuous production, sheet-like cushioning pads need to be overlapped and wound into rolls. Currently, the overlapping process mainly relies on manual operation, which easily leads to inconsistent seam gaps and misalignment of the front and rear sheets. In this embodiment, a conveyor belt 1, an overlapping platform 2, and a winding roller 3 are sequentially arranged. The conveyor belt 1 transports the cushioning pads to be overlapped one by one to the overlapping platform 2, while the winding roller 3 pulls the overlapped cushioning pads away from the overlapping platform 2 and winds them into rolls. By controlling the transport of the cushioning pads through equipment, the spacing and neatness between the overlapping cushioning pads can be ensured. Adhesive tape is applied to the beginning and end ends of the front and rear cushioning pads using an adhesive roller 21, thereby completing the overlap of the front and rear cushioning pads.

[0018] Please refer to Figure 1 and Figure 2 As shown, this utility model discloses a sheet splicing machine, which includes a conveyor belt 1, a splicing platform 2, and a take-up roller 3. The splicing platform 2 is connected to the discharge end of the conveyor belt 1. The splicing platform 2 has a splicing area. An adhesive roller 21 that moves perpendicular to the sheet movement direction is provided above the splicing area. The take-up roller 3 is located on the side of the splicing platform 2 away from the conveyor belt 1.

[0019] Working principle: The conveyor belt 1 transports the cushioning pads to be overlapped one by one to the overlapping platform 2. At the same time, the take-up roller 3 pulls the overlapped cushioning pads away from the overlapping platform 2 and winds them into a roll. The equipment controls the transport of the cushioning pads, ensuring the spacing and neatness between the overlapping cushioning pads. The adhesive roller 21 applies tape to the beginning and end of the two cushioning pads in the overlapping area of ​​the overlapping platform 2, thus completing the overlap of the two cushioning pads.

[0020] It is worth noting that before the first buffer pad is wound onto the take-up roller 3, the already overlapped buffer pads need to be manually pulled towards the take-up roller 3. Preferably, after each pull of the buffer pads, the positional relationship between the two overlapping buffer pads needs to be measured to ensure the uniformity of the overlap between the buffer pads in the entire roll as much as possible.

[0021] In some implementations, please refer to Figure 3As shown, pressure blocks 22 that can move toward the surface of the overlapping platform 2 are provided on both sides above the overlapping area. Before the adhesive roller 21 glues the front and rear buffer pads together, it presses the pressure blocks 22 onto the tail end of the front buffer pad and the front end of the rear buffer pad respectively to prevent the buffer pads from moving during the adhesive application process.

[0022] It is worth noting that the pressing block 22 is driven to perform the pressing operation by using devices with reciprocating moving ends, such as cylinders and hydraulic cylinders.

[0023] In some implementations, please refer to Figure 1 As shown, the sheet splicing machine also includes a first sensor 4, with its detection end facing the splicing area. The first sensor 4 is used to determine whether the buffer pad to be spliced ​​has entered the splicing area via the pressure block 22 near the conveyor belt 1. If the buffer pad is in place, the pressure block 22 near the conveyor belt 1 moves towards the splicing platform 2, thereby pressing the buffer pad to be spliced. The pressure block 22 away from the conveyor belt 1 operates when the rotation amount of the take-up roller 3 reaches a set value or when the first sensor 4 determines that the spliced ​​buffer pad has exited the splicing area by a certain amount.

[0024] In some implementations, please refer to Figure 1 , Figure 2 and Figure 4 As shown, a first linear reciprocating device 23 and a second linear reciprocating device 24 are provided above the overlapping platform 2. The first linear reciprocating device 23 is used to drive the adhesive roller 21 to move perpendicular to the sheet movement direction, and the second linear reciprocating device 24 is used to drive the adhesive roller 21 to move perpendicular to the table surface of the overlapping platform 2. The adhesive roller 21 is moved by the first linear reciprocating device 23 to stick the tape to the beginning and end of the front and rear cushioning pads, and the height between the adhesive roller 21 and the overlapping platform 2 is adjusted by the second linear reciprocating device 24 to accommodate the overlapping of cushioning pads of various thicknesses.

[0025] In some implementations, please refer to Figure 4 As shown, a fixed plate 25 and an adjusting plate 26 hinged to the fixed plate 25 are provided above the overlapping platform 2. A film roll 251 is provided on the fixed plate 25, and a cylinder 252 is hinged to the fixed plate 25. The movable end of the cylinder 252 is hinged to the adjusting plate 26, and an adhesive applicator roller 21 is provided on the adjusting plate 26. The film roll 251 is loaded with adhesive tape so that the adhesive tape roll can move with the adhesive applicator roller 21. The height between the film roll 251 and the overlapping platform 2 can be further adjusted by the cylinder 252.

[0026] It is worth noting that the film roll on the film roller 251 consists of two parts: an adhesive layer and a release liner. Alternatively, scissors (not shown in the figure) can be installed at the adhesive roller 21. After the adhesive roller 21 completes the overlap of the front and rear buffer pads, the scissors cut the tape. Another option is that the adhesive layer is pre-cut according to the bonding length of the overlapped buffer pads and attached to the release liner. Then, when the adhesive roller 21 resets, the adhesive layer will automatically separate from the release liner, avoiding pulling on the buffer pads. Subsequently, a robotic arm or other transfer equipment can be added to attach the cut release liner to the adhesive layer, preventing the adhesive layer from sticking to other buffer pads when the take-up roller 3 takes up the buffer pads.

[0027] In some implementations, please refer to Figure 4 As shown, the fixed plate 25 and / or adjusting plate 26 are provided with tension rollers 5. The tape on the film roll 251 is tensioned by the tension rollers 5 before being wound onto the adhesive roller 21, which helps to improve the stability of the tape output from the film roll 251.

[0028] In some implementations, please refer to Figure 1 As shown, a first pressing roller group 6 is provided between the overlapping platform 2 and the take-up roller 3. The first pressing roller group 6 includes a first upper pressing roller 61 and a first lower pressing roller 62 with their roller surfaces facing each other. A passage space is left between the first upper pressing roller 61 and the first lower pressing roller 62, and the height of the passage space is less than the thickness of the sheet. Because the height of the passage space between the first upper pressing roller 61 and the first lower pressing roller 62 is less than the thickness of the cushioning pad, the cushioning pad will undergo a certain deformation when entering the passage space. This not only ensures that the first pressing roller group 6 has sufficient friction to output the cushioning pad, but also improves the adhesion between the tape and the cushioning pad through the squeezing of the first upper pressing roller 61 and the first lower pressing roller 62.

[0029] In some implementations, please refer to Figure 2 As shown, a second pressure roller group 7 is provided between the conveyor belt 1 and the overlapping platform 2. The second pressure roller group 7 includes a second upper pressure roller 71 and a second lower pressure roller 72 with their roller surfaces facing each other. A passage space is left between the second upper pressure roller 71 and the second lower pressure roller 72. The height of the passage space is less than the thickness of the sheet material. The top of the roller surface of the second lower pressure roller 72 is flush with or lower than the transmission surface of the conveyor belt 1. The second pressure roller group 7 ensures that the buffer pads conveyed on the conveyor belt 1 can be transported to the designated position on the overlapping platform 2. At the same time, the passage space between the second upper pressure roller 71 and the second lower pressure roller 72 is less than the thickness of the buffer pads, ensuring that the second pressure roller group 7 has sufficient friction to output the buffer pads.

[0030] In some implementations, please refer to Figure 2As shown, the sheet splicing machine also includes a robotic arm 8 and a second sensor 9. The robotic arm 8 is located on one side of the conveyor belt 1, and the detection end of the second sensor 9 faces the discharge end of the second pressing roller group 7. The second sensor 9 is communicatively connected to the robotic arm 8. The robotic arm 8 picks up the buffer pad to be spliced ​​onto the conveyor belt 1 and, together with the conveyor belt 1, feeds the buffer pad into the second pressing roller group 7. At the same time, the second sensor 9 determines whether there is a buffer pad at the discharge end of the second pressing roller group 7. If a buffer pad is detected, the robotic arm 8 will release the buffer pad to avoid pulling it.

[0031] It is worth noting that, in order to ensure that the robotic arm 8 can feed the buffer pad into the second pressure roller group 7 for transfer, it is necessary to control the position of the robotic arm 8 in grasping the buffer pad to ensure that the leading end of the buffer pad has sufficient length to enter the second pressure roller group 7. Therefore, a camera (not shown in the figure) needs to be installed on the end effector of the robotic arm 8 to measure the reserved length of the leading end of the buffer pad. The reserved length of the leading end of the buffer pad is 220mm to 300mm.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
