The vacuum area can be connected to different numbers of adsorption holes 120, thereby making the length of the adsorption area of ​​the pressing head body 100 along the preset direction adjustable. After ensuring that the length of the adsorption area along the preset direction is compatible with the length of the FPC to be adsorbed, the vacuum area is connected to the vacuum to achieve the effect of the pre-pressing head structure 10 adsorbing the FPC. Compared with the pre-pressing head in the prior art, the pre-pressing head structure 10 in the present application can adjust the length of the adsorption area of ​​the pressing head body 100 along the preset direction through the adjusting component 200, so that the pre-pressing head structure 10 can be suitable for the adsorption of FPCs of various lengths, thereby realizing the universalization of the pre-pressing head structure 10, solving the problem of the need to replace the pre-pressing head for PFCs of different lengths, improving the efficiency of switching the production of PFC products of different lengths, and at the same time reducing the number of pre-pressing heads of various lengths, thereby reducing the production cost of PFC products.

[0031] The other end of the vacuum hole 110 can be a blind end or a connected end. When the other end of the vacuum hole 110 is a connected end, the connected end can be used as a vacuum access port, and the adjustment component 200 can also be installed correspondingly.

There are two adjustment components 200, which are correspondingly installed at both ends of the vacuum hole 110 and are respectively located on both sides of one end of the access hole 130 connected to the vacuum hole 110 along the preset direction. In this way, by increasing the number of adjustment components 200, the length adjustment range and flexibility of the adsorption area of ​​the pressure head body 100 are increased, and the practicality of the pre-pressure head structure 10 is improved.

[0033] Among them, the preset direction can be flexibly adjusted according to the needs of actual use. Specifically in this embodiment, the preset direction can be set to the length direction of the pressure head body 100.

The positions where the inner side wall of the vacuum hole 110 and the two adjustment components 200 are sealed and matched are respectively set to the first sealing position and the second sealing position, and the area of ​​the vacuum hole 110 between the first sealing position and the second sealing position is the vacuum area.

[0034] As shown in FIG. 1 , FIG. 3 and FIG. 4 , in one embodiment, the adjustment assembly 200 includes an adjustment member 201 and a sealing member 202. The sealing member 202 is located in the vacuum hole 110 and is sealed with the inner wall of the vacuum hole 110. One end of the adjustment member 201 extends into the vacuum hole 110 and is in transmission connection with the sealing member 202 to drive the sealing member 202 to move along a preset direction. In this way, the adjustment member 201 can drive the sealing member 202 to move back and forth in the vacuum hole 110 along a preset direction, thereby adjusting the length of the vacuum area of ​​the pressure head body 100, thereby improving the practicality of the pre-pressure head structure 10.

[0035] The adjusting member 201 may be configured as an adjusting rod, an adjusting tube or other adjusting structures. The sealing member 202 may be configured as a sealing ring, a sealing plug, a sealing sleeve or other sealing structures.

[0039] Among them, the fixing member 205 can be set as a fixing plate, a fixing seat or other fixing structure. The connecting member 206 can be set as a connecting plate, a connecting frame or other connecting structure.

The fixing member 205 is provided with a sliding hole for slidingly cooperating with the indicating member 207 along a preset direction. The indicating member 207 can be fixed to the connecting member 206 by snap-on, plug-in, screw connection or other means. When the two adjusting components 200 are correspondingly installed at the two ends of the vacuum hole 110, along the preset direction, the spacing between the two indicating members is the same as the length of the vacuum area.

[0040] As shown in FIG. 1 and FIG. 4 , optionally, the adjusting member 201 further includes an indicating scale 208, which is located on one side of the indicating member 207 and is used to read the length of the adsorption area of ​​the pressure head body 100 along the preset direction.

[0041] Specifically in this embodiment, the two indicator scales 208 are integrally formed and extend in a preset direction, and the zero scale lines in the two indicator scales 208 coincide with each other. By reading the scale values ​​corresponding to the ends of the two indicator members 207 that are close to each other and summing them, the length of the adsorption area of ​​the pressure head body 100 along the preset direction is obtained. In other embodiments, the position information of the indicator member 207 can also be detected and obtained by a detection element such as a camera, an image sensor or a distance sensor.

[0042] In one embodiment, the fixing member 205 is provided with a threaded hole extending in a preset direction, and the outer wall of the adjusting member 201 is provided with an external thread, which is threadedly matched with the threaded hole.
