Description

Technical Field

[0001] This application relates to the field of hot-press connection manufacturing technology, and in particular to a large-size FPC hot-press head. Background Technology

[0002] Currently, the hot-pressing process in LCD module bonding equipment is a critical process, and the stability of the hot-pressing process directly affects the quality of the product.

[0003] Hot pressing is a process that uses high temperature and high pressure to press products together. Therefore, a certain pressure needs to be applied to the pressing head mechanism to heat the pressing head, and the surface of the pressing head needs to be kept horizontal with the surface of the product during the pressing process.

[0004] Because the pressure head and its auxiliary mechanisms are made of metal, the material is prone to deformation under high temperature and pressure, causing the surface of the pressure head to change horizontally with the product surface. Therefore, a horizontal adjustment mechanism is needed to adjust the relative parallelism between the pressure head surface and the product surface. This is especially true for medium and large-sized LCD products, which have longer bonding areas, requiring longer pressure heads and thus placing higher demands on the stability of the hot-pressing pressure head mechanism.

[0005] Currently, the FPC hot pressing level adjustment mechanism has a complex structure, is inconvenient to adjust, and is also inconvenient to replace the pressure head. Summary of the Invention

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.

[0035] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0036] like Figure 1 , Figure 3 As shown, this application provides a large-size FPC hot press head 10, which includes a substrate 100, a first adjustment component, a second adjustment component, a third connecting seat 800, a driving component 810, a transmission seat 820, a base 50, a heating seat 60, a press head 70, and a height equalization column 75.

[0037] like Figure 5 As shown, the substrate 100 is a rectangular metal plate, which can be made of No. 45 steel. No. 45 steel has the advantages of high strength and strong resistance to deformation. The substrate 100 has a first through hole 600 in the center.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, the first adjustment assembly includes a first connecting seat 200, a first pivot member 300, a fixing block 20, a first adjusting screw 30, and a first locking screw 40. The first pivot member 300 includes a first shaft 320 and a first flange 310 connected to each other. The first flange 310 is fixedly connected to the first connecting seat 200. The first shaft 320 passes through the first connecting seat 200 and extends into the first through hole 600. Without other structural restrictions, the first adjustment assembly can make the first connecting seat 200 rotate relative to the substrate 100 based on the first pivot member 300. The fixing block 20 is fixed on the substrate 100. The fixed block 20 is aligned with the first side plate 230. There is a fixed block 20 on each of the two first side plates 230. The first adjusting screw 30 is threadedly connected to the fixed block 20. When the first adjusting screw 30 rotates relative to the threaded hole of the fixed block 20, it can increase or decrease the push on the first connecting seat 200, thereby adjusting the degree of rotation of the first connecting seat 200 relative to the base plate 100 based on the first pivot 300. The first locking screw 40 is used to lock the position of the first connecting seat 200 relative to the base plate 100 through the cooperation of the first fixing hole 620 and the first waist-shaped hole 630 after the first adjusting screw 30 is adjusted.

[0039] The base 50 is connected below the first connecting seat 200 and can transmit the rotational displacement generated by the first connecting seat 200 to adjust the stability of the large-size FPC hot press head 10.

The second flange 510 is fixedly connected to the first connecting seat 200. The second shaft 520 passes through the first connecting seat 200 and extends into the second through hole 700. When there are no other structural restrictions, the second adjusting assembly can make the second connecting seat 400 rotate relative to the first connecting seat 200 based on the second pivot member 500. The tensioning screw 110 is inserted into the second connecting seat 400 and threadedly connected to the first connecting seat 200.

[0044] When the tensioning screw 110 rotates relative to the internal threaded hole of the first connecting seat 200, the tension of the second connecting seat 400 relative to the first connecting seat 200 can be increased or decreased. The pushing screw 120 is threadedly engaged with the second connecting seat 400. The first connecting seat 200 is fixed on the base plate 100. When the pushing screw 120 rotates relative to the internal threaded hole of the second connecting seat 400, the pushing degree of the second connecting seat 400 relative to the first connecting seat 200 can be increased or decreased. The tensioning screw 110 and the pushing screw 120 are threadedly engaged with the second connecting seat 400. The push screw 120 is threadedly connected to different connecting seats. By increasing or decreasing the tension or pushing degree of the second connecting seat 400 relative to the first connecting seat 200, the rotation of the second connecting seat 400 relative to the first connecting seat 200 based on the second pivot 500 is adjusted. The second locking screw 130 is used to lock the position of the second connecting seat 400 relative to the first connecting seat 200 through the cooperation of the second fixing hole 720 and the second waist-shaped hole 730 after the tension screw 110 and the pushing screw 120 are adjusted.
