Description

Technical Field

[0001] This application relates to the field of FPC hot pressing technology, and in particular to a hot pressing head with rotation correction. 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. During the pressing process, the surface of the pressing head and the surface of the product need to be kept horizontal.

[0004] Because the pressure head and its auxiliary components are made of metal, the material is prone to deformation under high temperature and pressure, causing the surface of the pressure head to change from being horizontal to the surface of the product. Therefore, a horizontal adjustment mechanism is needed to adjust the relative parallelism between the surface of the pressure head and the surface of the product. In particular, for medium and large-sized LCD products, the bonding area is longer, requiring a longer pressure head, which places higher demands on the stability of the hot pressing pressure head mechanism. Currently, the FPC hot pressing horizontal adjustment mechanism has a complex structure, is inconvenient to adjust, and has low fine-tuning accuracy. Summary of the Invention

[0058] like Figures 1 to 4 As shown, this application provides a hot press head 10 with rotation correction, which includes a base 100, a rotating assembly 200 and a hot press assembly 300.

[0059] The base 100 is provided with a base hole 110, which is a circular through hole.

[0060] The rotating assembly 200 includes a rotating motor 210 and a rotating cylinder 220. The rotating motor 210 is provided with a rectangular block 230. The output end of the rotating motor 210 passes through the rectangular block 230. The rotating motor 210 is installed on the upper side of the base 100 corresponding to the base hole 110. The rotating cylinder 220 is connected to the output end of the rotating motor 210 and is located on the lower side of the base 100.

[0061] The hot pressing assembly 300 includes a heating base 310 and a pressing head 320. The heating base 310 rotates synchronously with the rotating cylinder 220. The pressing head 320 is connected to the heating base 310. The lower surface of the pressing head 320 is provided with a plurality of vacuum adsorption holes 330 for adsorbing the FPC to be hot pressed.

[0062] The rotating component 200 is used to pick up the FPC to be hot-pressed at a reverse compensation angle according to the incoming deflection angle of the FPC to be hot-pressed, and perform hot-pressing and pasting operations after rotational correction.

[0063] like Figure 1 , Figure 2 , Figure 3 As shown, the base 100 includes a base block 120 and a side block 130. The base block 120 is provided with a base hole 110. The side block 130 is connected to both sides of the base block 120. The rectangular block 230 is matched and fitted with the upper part of the base block 120 and the side block 130. The hot press head 10 with rotation correction also includes a lifting assembly 400. The lifting assembly 400 is connected to the side block 130 to drive the base 100 to rise and fall in the Z direction.

[0064] like Figure 5 , Figure 6As shown, the lifting assembly 400 includes a base plate 410, a lifting motor 420, a lead screw 430, a lead screw nut 440, a lifting slide rail 450, and a lifting slider 460.

[0065] The substrate 410 is a rectangular plate, and lifting slots 412 are provided on the substrate 410 at parallel intervals.

[0066] The lifting motor 420 is mounted on one side of the base plate 410, with its upper end protruding from the upper end of the base plate 410.

[0067] The lead screw 430 is located on the same side of the base plate 410 as the lifting motor 420 and is driven to rotate through the output end of the lifting motor 420.

[0068] The lead screw 440 is threaded to the lead screw 430 and passes through the base plate 410 and is connected to the side block 130 via the lifting groove 412. The rotation of the lead screw 430 causes the lead screw 440 to move up and down in the lifting groove 412, thereby causing the side block 130 to move up and down.

[0069] The lifting slide rails 450 are arranged parallel to each other on one side of the base plate 410, which is spaced apart from the lifting motor 420. The lifting slide rails 450 are correspondingly arranged on the outside of the lifting channel 412. The length of the lifting slide rails 450 is longer than the length of the lifting channel 412. The bottom of the lifting slide rails 450 is flush with the bottom of the base plate 410.

[0070] The lifting slider 460 is fixed to the side block 130 and slidably disposed on one side of the base plate 410, spaced from the lifting motor 420. The lifting slider 460 is disposed on the lifting slide rail 450. The lifting slider 460 and the side block 130 are connected by bolts. When the nut 440 drives the side block 130 to move up and down, the side block 130 and the lifting slider 460 move up and down on the lifting slide rail 450.

[0071] like Figure 7 As shown, the hot press head 10 with rotation correction also includes a pressure application assembly 500, which includes a rotating horizontal plate 510, a rotating vertical plate 520, a pressure application slide rail 530, a pressure application slider 540, a transmission plate 550, and a pressure application cylinder 560.

[0072] The rotating horizontal plate 510 is a rectangular horizontal plate with a circular through hole. The rotating horizontal plate 510 is connected to the bottom of the rotating cylinder 220 by a threaded connection so that the rotating horizontal plate 510 rotates together with the rotating cylinder 220 when it rotates.

[0073] The rotating vertical plate 520 is connected to the side of the rotating horizontal plate 510, and the upper end of the rotating vertical plate 520 and the upper end surface of the rotating horizontal plate 510 are on the same horizontal plane.

[0074] The pressure slide rail 530 is vertically mounted on the rotating vertical plate 520 near the rotating horizontal plate 510 and is connected to the rotating vertical plate 520.

[0075] The pressure slider 540 and the pressure rail 530 are in sliding engagement.

[0076] The upper part of the transmission plate 550 is fixed to the pressure slider 540 by a threaded connection, and the lower part of the transmission plate 550 is connected to the hot pressing assembly 300 by transmission.

[0077] The pressure cylinder 560 is mounted on the rotating horizontal plate 510 and located on the inner circumference of the rotating cylinder 220. The drive end of the pressure cylinder 560 passes through a circular through hole and is connected to the transmission plate 550.

[0078] like Figure 8 As shown, the hot press head 10 with rotation correction also includes a support assembly 600, which includes a support frame 610, a rotating block 620, a mating block 630, and an arc-shaped cross guide rail 640.

[0079] The support frame 610 and the side block 130 are fixedly connected by bolts. The support frame 610 encloses the rotating block 620, the mating block 630, and the arc-shaped cross guide rail 640 between the support frame 610 and the side block 130.

[0080] The rotating block 620 is fixedly connected to the rotating horizontal plate 510. When the rotating horizontal plate 510 is driven to rotate by the rotating cylinder 220, the rotating block 620 is also driven to rotate. The rotating block 620 has an outer arc-shaped surface.

[0081] The left and right widths of the mating block 630 correspond to and match the inner width of the support frame 610. The mating block 630 is fixedly connected to the support frame 610 by bolts and is spaced apart from the rotating block 620. The mating block 630 has an inner arc-shaped surface corresponding to the outer arc-shaped surface.

[0082] The arc-shaped cross guide rail 640 is set between the inner arc-shaped surface and the outer arc-shaped surface. The rotating block 620 is driven by the rotating horizontal plate 510 to rotate in a time delay of the arc-shaped cross guide rail 640.

[0083] like Figure 7 , Figure 9 As shown, the bottom of the transmission plate 550 is connected to the reference plate 570, and the hot press head 10 with rotation correction also includes a fine adjustment component 700, which includes an adjustment seat 710, a lever shaft 720 and a lever screw 730.

[0084] The adjusting seat 710 includes a base plate 712 and a side plate 714. There is a gap between the base plate 712 and the reference plate 570, so that the base plate 712 can move relative to the reference plate 570. The side plate 714 is located on both sides of the reference plate 570.

[0085] The lever axis 720 passes through the two side plates 714 and the reference plate 570 so that the base plate 712 can swing left and right relative to the reference plate 570 based on the lever axis 720.

[0086] The lever screw 730 passes through the reference plate 570 and abuts against the base plate 712. In this embodiment, the interval transmission plate 550 is provided with two lever screws 730. By adjusting the lever screws 730 to abut against the base plate 712, the base plate 712 can swing left and right relative to the reference plate 570 to adjust the levelness, thereby fine-tuning the levelness of the pressure head 320.

[0087] like Figure 9 As shown, the fine-tuning component 700 also includes lever nuts 740. In this embodiment, two lever nuts 740 cooperate with two lever screws 730 to lock the lever screws 730 and prevent the lever screws 730 from rotating on their own, which would affect the stability of the level of the base plate 712.

[0088] like Figure 9 As shown, the fine-tuning component 700 also includes a locking screw 750. The side plate 714 is provided with an arc-shaped slot, and the reference plate 570 is provided with a side fixing hole. The locking screw 750 is used to pass through the arc-shaped slot and lock onto the side fixing hole after the lever screw 730 has been adjusted, so as to lock the position of the adjusting seat 710 relative to the reference plate 570, making the relative position after adjustment more stable. The locking screw 750 is smaller than the lever shaft 720. In this embodiment, two locking screws 750 are provided with a gap between the lever shaft 720. Of course, four or eight can also be provided.

[0089] like Figure 9 As shown, the fine-tuning assembly 700 also includes a clamping plate seat 760, a tensioning screw 770, a pushing screw 780, and a pushing nut 782.

[0090] The clamping plate base 760 is integrally formed and has a transverse groove 790. The clamping plate base 760 includes an upper clamping plate 762 and a lower clamping plate 764 located in the transverse groove 790. The upper clamping plate 762 is fixedly connected to the base plate 712, and the heating base 310 is connected to the lower clamping plate 764. The level of the pressure head 320 can be finely adjusted by adjusting the size of the transverse groove 790.

[0091] The tensioning screw 770 passes through the upper clamping plate 762 and is threaded into the lower clamping plate 764 at the opening of the transverse groove 790. By adjusting the tensioning screw 770, the lower clamping plate 764 is tightened relative to the upper clamping plate 762, so that the transverse groove 790 becomes smaller. In this embodiment, two tensioning screws 770 are symmetrically arranged at intervals of lever shaft 720.

[0092] The push screw 780 is threadedly engaged with the upper clamping plate 762 at the opening of the transverse groove 790 and abuts against the upper surface of the lower clamping plate 764. The push screw 780 is adjusted to push the lower clamping plate 764 away from the upper clamping plate 762. In this embodiment, two push screws 780 are provided, and the push screw 780 is located outside the tensioning screw 770.

[0093] The push nut 782 is threadedly engaged with the push screw 780 to lock the position of the push screw 780, preventing the push screw 780 from rotating on its own and affecting the stability of the size adjustment of the transverse groove 790, thereby ensuring the stable maintenance of the horizontality of the pressure head 320.

[0094] like Figure 1 As shown, the hot press head 10 with rotation correction also includes a heat insulation plate 800 and a bracket 900. The heat insulation plate 800 is connected between the lower clamping plate 764 and the heating base 310. The bracket 900 is used to support the non-absorbent area of ​​the FPC to be hot-pressed, preventing the non-absorbent area of ​​the FPC from being damaged during operation.

[0095] In summary, those skilled in the art will readily understand that the hot press head 10 with rotation correction provided in this application allows the fine-tuning component 700 to adjust the horizontality of the workpiece to be hot-pressed before operation. By adjusting the lever screw 730 to abut against the base plate 712, the base plate 712 can be swayed left and right relative to the reference plate 570. Adjusting the tension screw 770 and the push screw 780 can adjust the size of the transverse groove 790, thereby adjusting the horizontality of the press head 320 on the X and Y axes. After the horizontality is adjusted, operation begins. The FPC is conveyed to the shooting area via a conveyor belt. The shooting area captures the incoming deflection angle of the FPC. Then, the rotation component 200 rotates with a reverse compensation angle according to the incoming deflection angle of the FPC to be hot-pressed, so that the press head 320 picks up the FPC to be hot-pressed and performs rotation correction. After rotation correction, the press head 320 performs hot-pressing bonding operation between the FPC to be hot-pressed and the workpiece. The structure is simple and greatly reduces the error rate of hot-pressing bonding operation.

[0096] The above embodiments of this application are merely illustrative examples to clearly illustrate the purpose of this application, and are not intended to limit the implementation of this application. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
