Description

Technical Field

[0001] This application relates to the field of automated processing equipment, and in particular to a hot press. Background Technology

[0002] Hot presses, also known as bonding machines, are generally divided into COG hot presses and FOG hot presses. FOG (FPC on Glass) uses ACF (anisotropic conductive film) for bonding. Under certain temperature, pressure, and time conditions, the conductive particles in the ACF are broken down and the ACF adhesive is cured, thereby achieving mechanical and electrical connections between the LCD (liquid crystal display) and the FPC (flexible printed circuit board).

[0003] In related technologies, the hot press production process mainly consists of several steps: ACF bonding, FPC feeding, pre-pressing, and final pressing. Before ACF bonding, the ACF needs to be cut in half. In actual production, the ACF needs to be cut into two sections before the FPC and LCD are assembled.

[0004] Regarding the aforementioned technical means, existing FPCs include both LCD and touch screen types. However, whether it is an LCD FPC or a touch screen FPC, the assembly with the LCD is a single-segment ACF. However, the machines on the market cut the ACF into two segments, and one of the segments of the two-segment ACF is too short, resulting in a problem of machine mismatch. Summary of the Invention

[0005] To overcome the problem of machine tool mismatch, this application provides a hot press.

[0006] This application provides a hot press, which adopts the following technical solution:

[0007] A hot press, comprising

[0008] A cutting device for halving ACF;

[0009] A bonding device is used to attach and pre-press ACF onto FPCs and LCDs;

[0010] Assembly table, used to transport FPCs and LCDs to be attached and pre-pressed;

[0011] Transfer handles are used to carry and transport FPCs and LCDs that have been attached and pre-pressed to the next process.

[0012] This pressing device is used to further press the ACF onto the FPC and LCD;

[0013] A substrate is used to mount the cutting device, the pressing device, the assembly table, the transfer hand, and the pressing device, wherein the assembly table and the transfer hand slide on the substrate. The substrate includes a flat plate and a support, and the support is vertically fixed on the flat plate.

[0014] The cutting device is mounted on the bracket. The cutting device includes a cutting blade, a fixed frame, a cutting lifting component, and a cutting moving component. The cutting blade and the cutting lifting component are both fixed on the fixed frame, and one end of the cutting lifting component abuts against the cutting blade. The fixed frame is fixed on the cutting moving component. The cutting moving component includes a moving plate and a moving drive component that drives the moving plate to move. The fixed frame is fixed on the moving plate.

[0015] By adopting the above technical solution, after the FPC and LCD are transported to the assembly table by the transfer unit, the cutting and moving component moves the fixing frame, causing the cutter on the fixing frame to move along the ACF feeding direction. The cutting lifting component then drives the cutter to perform a partial cut towards the ACF. After the partial cut is completed, the assembly table moves the FPC and LCF under the bonding and pressing device for bonding and pre-pressing, and then the transfer unit transports them to the next process. Before the next set of bonding and pre-pressing, the cutting and moving component and the cutting lifting component again drive the cutter to perform a partial cut, separating it from the previously partially cut ACF, thus achieving a single-segment ACF and overcoming the problem that the machine cannot cut a single-segment ACF.

[0016] Optionally, the fixing frame includes a cutter clamping component, a cutter slider, and a mounting block. The cutter is fixed on the cutter clamping component, the cutter clamping component is mounted on the cutter slider, the cutter slider is fixed on the mounting block, and the cutting lifting component is disposed on the mounting block. The mounting block is fixedly connected to the moving plate.

[0017] By adopting the above technical solution, the cutter is clamped on the cutter clamping part, which is in turn fixed to the cutter slider, so that the cutter can move vertically under the action of the cutting lifting part to partially cut the ACF.

[0018] Optionally, the mounting bracket further includes a baffle disposed at the end of the mounting block away from the cutting lifting member, and the ACF passes through the space between the baffle and the cutter.

[0019] By adopting the above technical solution, the baffle not only prevents the ACF from shaking randomly when feeding, but also provides a cutting blade for the cutter to partially cut the ACF, so as to ensure that partial cutting can be achieved.

[0020] Optionally, the cutting device further includes a fine-adjustment ruler fixed on the fixed frame. The fine-adjustment ruler includes a fine-adjustment limit block, a micrometer, and a mounting block. The mounting block is connected to the cutting clamping member, the fine-adjustment limit block is connected to the mounting block, and the micrometer is disposed on the mounting block, with one end of the micrometer abutting against the fine-adjustment limit block.

[0021] By adopting the above technical solution, rotating the micrometer can finely adjust the distance between the cutter and the baffle, which on the one hand avoids damage to the tip of the cutter, and on the other hand avoids cutting the protective film of ACF when the cutter cuts, thus preventing the ACF roll from being cut.

[0022] Optionally, the bonding device is mounted on the bracket. The bonding device includes a bonding assembly and a bonding drive for driving the bonding assembly. The bonding assembly includes a connecting block and a bonding head mounted on the connecting block, and the connecting block is fixedly connected to the bonding drive.

[0023] By adopting the above technical solution, the pressure head is located directly above the ACF. Under the drive of the pressure driving component, the ACF is pressed onto the FPC and LCD to achieve integrated bonding and pre-pressing.

[0024] Optionally, the bonding assembly further includes a buffer block disposed between the connecting block and the bonding head, the buffer block having a buffer gap.

[0025] By adopting the above technical solution, during the process of the pressing head being pressed down vertically by the pressing drive component, the buffer gap can mitigate the reaction force when pressing on the FPC and LCD, thus avoiding the pressure being entirely applied to the FPC and LCD during pressing and causing unnecessary damage.

[0026] Optionally, the hot press also includes an anti-sticking device mounted on the bracket away from the cutting device, the anti-sticking device including an anti-sticking drive and an anti-sticking block connected to the drive shaft of the anti-sticking drive, with the ACF resting on the anti-sticking block.

[0027] By adopting the above technical solution, the anti-stick block moves towards the assembly table under the action of the anti-stick drive component. Since the ACF is placed on top of the anti-stick block, during the movement, because the height of the anti-stick block is higher than that of the ACF, the ACF is lifted up and detached from the FCP and LCD.

[0028] Optionally, the anti-stick block has an anti-stick rod, the ACF rests on the anti-stick rod, and the anti-stick rod is higher than the plane of the assembly table.

[0029] By adopting the above technical solution, the anti-stick bar can reduce the contact area with ACF and avoid repeated friction between the anti-stick block and ACF.

[0030] Optionally, the hot press also includes a testing device mounted on the bracket, the testing device including a testing lens and a testing fixing block for mounting the testing lens, the testing lens being arranged perpendicular to the assembly table.

[0031] By adopting the above technical solution, the setting of the inspection lens allows for a positional alignment before the ACF is pressed onto the FCP and LCD, thereby ensuring that errors or defective products are reduced during assembly.

[0032] Optionally, the detection device further includes a detection slider with a groove, and the detection fixing block has a sliding boss protruding from it, with the groove slidingly engaging with the sliding boss.

[0033] By adopting the above technical solution, the sliding fit setting enables control of the detection position of the detection lens, and allows for flexible adjustment of various sizes of FPCs and LCDs.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. Single-segment half-cut ACF adapts to various assembly needs. After the FPC and LCD are transported to the assembly table by the transfer unit, the cutting and moving component moves the fixing frame, causing the cutter on the fixing frame to move along the ACF feeding direction. The cutting lifting component drives the cutter to make a half-cut towards the ACF located below the guard edge. After the half-cut is completed, the assembly table moves the FPC and LCF to the bonding and pre-pressing device for bonding and pre-pressing, and then the transfer unit transports them to the next process. Before the next set of bonding and pre-pressing, the cutting and moving component and the cutting lifting component drive the cutter to make a half-cut, thus separating the ACF from the previous set of half-cuts, thereby achieving single-segment ACF and overcoming the problem that the machine cannot cut single-segment ACF.

[0036] 2. ACF anti-sticking. The anti-stick block moves towards the assembly table under the action of the anti-sticking drive. Since the ACF rests on top of the anti-stick block, during the movement, because the height of the anti-stick block is higher than the ACF, the ACF is lifted up and detached from the FCP and LCD.

[0037] 3. Alignment Inspection. The inspection lens is designed to ensure alignment before the ACF is pressed onto the FCP and LCD, thereby reducing errors or defective products during assembly. Attached Figure Description

[0056] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0057] This application discloses a hot press. (Refer to...) Figure 1 and Figure 2 A hot press includes a substrate 1, a cutting device 2, a pressing device 3, an assembly table 4, a transfer arm 5, a pressing device 6, an anti-sticking device 7, a detection device 8, and a feeding device 9. The substrate 1 includes a horizontally placed flat plate 11 and a support 12 vertically fixed on the flat plate 11. The cutting device 2, pressing device 3, anti-sticking device 7, and detection device 8 are all fixed to the front of the support 12. The assembly table 4, transfer arm 5, pressing device 6, and feeding device 9 are all fixed to the flat plate 11. The pressing device 6 is located on the other side of the support 12, and the assembly table 4 is oriented perpendicular to the support 12. The transfer arm 5 is oriented parallel to the support 12. Furthermore, two assembly tables 4 and two transfer arms 5 are provided to improve the machine's working efficiency.

[0058] Reference Figure 2 and Figure 3 The support 12 is fixed with a feeding roller 121, a receiving roller 122, a feeding motor 123, and a receiving motor 124. The feeding roller 121 and the receiving roller 122 are located on the front of the support 12, with the feeding roller 121 on the left and the receiving roller 122 on the right. The feeding motor 123 and the receiving motor 124 are both located on the back of the support 12. The feeding motor 123 drives the feeding roller 121 to feed the ACF, and the receiving motor 124 drives the receiving roller 122 to collect the ACF. The feeding device 9 includes a feeding robot 91, a feeding platform 92, and two feeding detection lenses 93. The feeding robot 91 is located on the back of the support 12. The feeding platform 92 is set in a direction perpendicular to the support 12 and is located between two assembly tables 4. The feeding detection lenses 93 are located at the far end of one side of the assembly table 4. After the LCD FPC or touch FPC is placed on the feeding platform 92, the feeding robot 91 grabs it and moves it to the feeding detection lens 93 for alignment, and then puts it into the assembly table 4.

[0059] Reference Figure 4 and Figure 5The cutting device 2 is located on the left side of the bracket 12, and specifically includes a cutter 21, a fixing frame 22, a cutting lifting component 23, a cutting shifting component 24, and a fine-tuning ruler 25. The cutting shifting component 24 is horizontally fixed on the bracket 12, and the fixing frame 22 is locked to the cutting shifting component 24 by bolts. The cutter 21, the cutting lifting component 23, and the fine-tuning ruler 25 are all fixed on the fixing frame 22. The fixing frame 22 includes a cutter clamping component 221, a cutter slider 222, a mounting block 223, a baffle 224, and a cutting fixing plate 225. The cutter clamping component 221 has a cutter slot 2211, which is provided with a cutter pressing block 2212. The cutter 21 is placed in the cutter slot 2211 and is clamped in the cutter slot 2211 by the cutter pressing block 2212, so that the tip of the cutter 21 faces upward.

[0060] Reference Figure 4 and Figure 5 The cutter clamping component 221, the cutter slider 222, the baffle 224, and the cutting fixing plate 225 are all bolted to the mounting block 223. Specifically, the mounting block 223 is vertically fixed to the cutting transfer component 24, the cutting fixing plate 225 is perpendicular to the mounting block 223 and fixed to the lower side of the mounting block 223, the baffle 224 is perpendicular to the mounting block 223 and fixed to the upper side of the mounting block 223, the cutter slider 222 is disposed between the cutting fixing plate 225 and the baffle 224 of the fixing frame 22, and the cutter slider 222 consists of a guide rail 2221 and a slider 2222. The guide rail 2221 is fixed between the cutting fixing plate 225 and the baffle 224 of the fixing frame 22, and the slider 2222 slides on the guide rail 2221 and is limited by the cutting fixing plate 225 and the baffle 224. The cutter clamping member 221 is connected to the slider 2222, and the cutting lifting member 23 is inserted into the cutting fixing plate 225, with one end of the cutting lifting member 23 abutting against the cutter clamping member 221, so that the cutter 21 can reciprocate in the vertical direction. In this embodiment, the cutting lifting member 23 is a needle cylinder.

[0061] Furthermore, the tip of the cutter 21 faces the lower surface of the baffle 224, and the ACF passes through the space between the cutter 21 and the baffle 224. Driven by the cutting lifting member 23, the cutter clamping member 221 moves toward the baffle 224, thereby causing the tip of the cutter 21 to cut the ACF located below the baffle 224, thus achieving a partial cut of the ACF. The baffle 224 is not only designed to prevent the ACF from shaking during feeding, but also provides a cutting plate for the cutter 21 to partially cut the ACF, ensuring that a partial cut can be achieved.

[0062] Reference Figure 4 and Figure 5The cutting and shifting component 24 includes a shifting movable plate 241 and a shifting drive component 242. The drive shaft of the shifting drive component 242 is fixedly connected to the shifting movable plate 241 to achieve the lateral reciprocating motion of the shifting movable plate 241. Specifically, the mounting block 223 on the fixing frame 22 is locked to the shifting movable plate 241 by bolts, thereby realizing the left and right movement of the cutter 21 to achieve a single-segment half-cut of the ACF. In this embodiment, the shifting drive component 242 is a cylinder.

[0063] The fine-tuning ruler 25 includes a fine-tuning limit block 251, a micrometer 252, and a fine-tuning mounting plate 253. The fine-tuning limit block 251 is fixed to the side of the mounting block 223, and the fine-tuning mounting plate 253 is fixed to the side of the cutter clamping member 221. The fine-tuning mounting plate 253 and the fine-tuning limit block 251 are located on the same side. The micrometer 252 is inserted through the fine-tuning mounting plate 253, and one end of the micrometer 252 abuts against the fine-tuning limit block 251. By rotating the micrometer 252, the distance between the cutter 21 and the baffle 224 can be finely adjusted. This avoids damage to the tip of the cutter 21 and prevents the cutter 21 from cutting through the protective film of the ACF, thus preventing the ACF roll from being cut.

[0064] Reference Figure 6 Two bonding devices 3 are provided and located in the middle of the bracket 12. Specifically, they include a bonding assembly 31 and a bonding drive 32. The bonding drive 32 is vertically fixed to the bracket 12, and the bonding assembly 31 is vertically fixed to the bonding drive 32. The bonding assembly 31 is located above the assembly table 4. The bonding assembly 31 includes a connecting block 311, a bonding head 312, and a buffer block 313. The connecting block 311 is locked to the bonding drive 32 by bolts. The buffer block 313 is fixedly connected to the lower end of the connecting block 311, and the bonding head 312 is fixedly connected to the lower end of the buffer block 313. The buffer block 313 has a buffer gap 3131, which is open on the front of the buffer block 313 and extends from the left to the right. This buffer gap 3131 can mitigate the reaction force on the FPC and LCD when the bonding drive 32 drives the bonding head 312 to press down vertically, thus avoiding damage. In this embodiment, the pressure drive 32 is a cylinder.

[0065] Reference Figure 7The anti-sticking device 7 is located on the right side of the bracket 12, specifically including an anti-sticking drive 71 and an anti-sticking block 72. The anti-sticking block 72 is fixedly connected to the anti-sticking drive 71. The anti-sticking drive 71 is arranged horizontally. The eggplant anti-sticking block 72 has two parallel anti-sticking sliding rods 721, and the anti-sticking sliding rods 721 are perpendicular to the bracket 12. The ACF contacts and rests on the anti-sticking sliding rods 721, so that when the pressing head 312 presses the ACF onto the FPC and LCD, the height of the ACF on the FPC and LCD is lower than the anti-sticking sliding rods 721, and the height of the assembly table 4 is lower than the anti-sticking sliding rods 721. Under the action of the anti-sticking drive 71, the anti-sticking sliding rods 721 move towards the assembly table 4, thereby lifting the ACF pressed on the FPC and LCD, thus removing the ACF from the FPC and LCD. In this embodiment, the anti-sticking drive 71 is a cylinder.

[0066] Reference Figure 8 The detection device 8 has two components, located in the middle of the bracket 12 and above the pressing device 3. The detection device 8 includes a detection fixing block 82, two detection lenses 81, and two detection sliders 83. The detection fixing block 82 is bolted to the bracket 12. The detection lenses 81 are fixedly connected to the detection sliders 83, and the detection lenses 81 are vertically oriented, facing the FPC and LCD on the assembly table 4. Furthermore, the two detection lenses 81 and the two detection sliders 83 are symmetrically arranged. The detection sliders 83 have a groove 831, and the detection fixing block 82 protrudes from a sliding boss 821. The groove 831 and the sliding boss 821 slide and engage to achieve lateral adjustment of the detection lenses 81. Specifically, the groove 831 is a dovetail groove, and the sliding boss 821 is a dovetail boss, thus preventing disengagement during adjustment.

[0067] The implementation principle of a hot press according to an embodiment of this application is as follows:

[0068] The transfer arm 5 places the FPC and LCD sequentially onto the assembly table 4. The assembly table 4 moves towards the support 12 and moves below the detection device 8, where it is inspected by the detection lens 81. The cutting and shifting component 24 on the cutting device 2 drives the cutter 21 to move to the right, and then the cutting lifting component 23 drives the cutter 21 to partially cut the ACF, and then resets it. Subsequently, the assembly table 4 moves to the pressing device 3, and the pressing drive component 32 drives the pressing head 312 to press the ACF onto the FPC and LCD. After pressing, the anti-sticking rod 721 moves to the left under the action of the anti-sticking drive component 71 to lift the pressed ACF, which is then inspected by the detection lens 81. Finally, the transfer arm 5 transports it to the pressing device 6. If the LCD requires both a liquid crystal FPC and a touch FPC, the other FPC will be placed on the assembly table 4 by the gripper of the feeding robot 91.
