The rotating shaft 121 is connected with the output end of the pressing driving assembly 13. The pressing driving assembly 13 is used to drive the rotating shaft 121 to rotate, so as to drive the first end of the pressing member 12 to approach or move away from the pressing platform 11. In this way, the pressing member 12 rotates to approach the pressing platform 11 under the driving of the pressing driving assembly 13. The rotating pressing uniformly distributes the pressure through the rotating motion, reduces the local stress concentration, and reduces the risk of damage to the soft flat cable. The rotating motion helps the soft flat cable surface to be more uniformly contacted, reduces the scratches and indentations, and further, the rotating pressing can better handle complex curved surfaces or irregular shapes, and ensure uniform distribution of pressure.

[0042] In an available embodiment, the pressing driving assembly 13 comprises a cylinder 131 and a gear 133 and a rack 132 transmission assembly. The telescopic end of the cylinder 131 is connected with the rack 132, and the gear 133 is connected with the rotating shaft 121 through a bearing. The use of the cylinder 131 and the gear 133 and the rack 132 transmission assembly makes the conversion efficiency between linear motion and rotating motion high, and almost no energy loss. The gear 133 and the rack 132 are composed of, the structure is compact, easy to install and maintain. The engagement precision of the gear and the rack 132 is high, and the carrying capacity is strong, and bidirectional motion (linear to rotating, or rotating to linear) can be realized. The structure is simple, easy to manufacture and maintain. The motion conversion efficiency is high. High-precision positioning can be realized. It is suitable for small and medium-sized load.

[0043] In an embodiment, the pressing driving assembly 13 further comprises a first sliding assembly 134 and a first limiting piece 135. The sliding end of the first sliding assembly 134 is connected with the rack 132. The first limiting piece 135 is arranged at one end of the sliding direction of the first sliding assembly 134, and is used for limiting the displacement of the rack 132. In this way, the first sliding assembly 134 can guide the transmission of the rack 132, improve the transmission accuracy, and also improve the stability of the transmission pressing. The first limiting piece 135 can prevent excessive pressing and excessive extrusion of the soft wire row, and damage the soft wire row.

[0044] In an embodiment, the first end of the pressing member 12 is provided with a pressing head assembly. The pressing head assembly comprises a connecting piece 122 and an elastic pressing head 123. The connecting piece 122 connects the pressing member 12 and the elastic pressing head 123. The elastic pressing head 123 is used for flexible contact with the soft wire row. In this way, the elastic pressing head 123 is in flexible contact with the soft wire row, avoiding damage such as scratches or indentations caused by rigid contact, and prolonging the service life of the soft wire row. The elastic pressing head 123 can uniformly disperse the pressure, prevent local stress concentration, and ensure the stability of the pressing quality. The elastic pressing head 123 can adapt to the thickness and shape changes of the soft wire row, and improve the pressing effect.

The negative pressure hole 111 can be flexibly arranged, and is suitable for soft wire rows of various shapes and sizes, thereby enhancing the universality of the equipment. Negative pressure fixation reduces the risk of damage to the soft wire row, and in combination with the pressing head, can ensure the stability of the pressing. Negative pressure fixation is fast and stable, reduces the adjustment time, and improves the production efficiency. In addition, the negative pressure assembly 14 has a simple structure, is easy to operate and maintain, and reduces the use cost.

This allows precise control in multiple directions, with the three drive members controlling vertical and horizontal movement respectively, enabling precise positioning of the jaw assembly 21 and improving film tearing accuracy. In addition, independent control of horizontal and vertical movement allows the device to adapt to soft wires and platforms of different shapes and sizes, enhancing flexibility. Multiple drive members work together to reduce adjustment time, speed up film tearing, and improve efficiency. It should be noted that the sub-jaws 211 of the jaw assembly 21 of the film tearing device 100 provided in the present application are not limited to five, but can be set according to the specific needs of the soft wire, which will not be described here.

[0047] Further, the film tearing drive assembly 22 also includes a second limiting member 224. By setting the second limiting member 224 in combination with the U-shaped structure of the bottom plate 212 of the jaw assembly 21, the distance of the jaw assembly 21 moving horizontally can be limited to avoid excessive displacement and reduce the risk of misoperation.

[0048] Further, as shown in Figure 8 The structure of the plurality of sub-jaws 211 can be designed according to the specific film tearing point position, which will not be described here. The fixed position of the plurality of sub-jaws 211 and the bottom plate 212 can also be provided with a through slot to facilitate fine adjustment of the position of the sub-jaw 211 and improve positioning accuracy.
