Description

Technical Field

[0001] This utility model relates to the technical field of FPC production and processing, specifically to a single-station FPC pressing mechanism. Background Technology

[0002] Flexible printed circuit boards (FPCs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They feature high wiring density, light weight, thinness, and good bendability. FPC bonding refers to the process in FPC manufacturing where pressure is applied to cure conductive adhesive (ACF) and bond the FPC to components such as ICs or glass. Bonding is a crucial step in the FPC assembly process, ensuring the stability and reliability of circuit connections. The main purpose of FPC bonding is to fully cure the ACF conductive particles by applying appropriate pressure and temperature, ensuring a stable and reliable electrical connection between the FPC and components such as ICs or glass. Improper bonding parameters can lead to problems such as excessively fragmented conductive particles and springback causing IC bonding separation bubbles, especially noticeable with thin LCD glass (≤0.15mm thick).

[0003] While existing pressure-sensitive devices on the market are evolving towards thinner, lighter, and more flexible FPCs with technological advancements to meet the demands of increasingly thinner and lighter electronic products, and while the conductivity and electrical properties of FPCs are continuously improving to meet the needs of more complex circuits, a drawback is that these devices, when used to fix circuit boards of different sizes, do not offer convenient adjustment mechanisms. This results in certain size limitations during use. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 As shown, this utility model is a single-station FPC pressing mechanism, including a support assembly 1, a movable fixing assembly 2 installed diagonally at the bottom of the support assembly 1, and a pressing assembly 3 installed in the middle of the top of the support assembly 1. A position moving assembly 4 is installed at the bottom of the pressing assembly 3, and the position moving assembly 4 is installed at the top of the middle of the support assembly 1. An adjusting clamping assembly 5 is installed at the top of the position moving assembly 4.

[0025] By installing the adjustable clamping component 5 on the device, when using this device to perform limit work on circuit boards of different sizes, the limit can be adjusted to different sizes by adjusting the clamping component 5. This makes the device more widely applicable during processing and avoids limitations in its use.

[0026] The support assembly 1 includes a workbench 101, with support rods 102 installed diagonally on the top of the workbench 101, and support frames 103 installed on both sides of the top of the workbench 101. A fixing plate 104 is installed on the top of the support frame 103. The installation conditions for the pressing assembly 3 can be provided by installing the support frame 103 on the top of the workbench 101 and the fixing plate 104 on the top of the support frame 103.

[0027] The movable fixing component 2 includes a connecting plate 201, which is installed diagonally at the bottom of the workbench 101. The bottom of the connecting plate 201 is equipped with a moving wheel 202, and a fixed telescopic rod 203 is installed on one side of the moving wheel 202. When moving, the moving wheel 202 installed at the bottom is used to move the work until it reaches the appropriate position. Then, the fixed telescopic rod 203 is used to extend and fix the work.

[0028] The pressing assembly 3 includes a hydraulic rod 301, which is installed at the top center of the fixed plate 104. A push rod 302 is installed at the bottom of the hydraulic rod 301, and a pressing end 303 is installed at the bottom of the push rod 302. A balance telescopic rod 304 is installed on the other side of the top of the pressing end 303. The top of the balance telescopic rod 304 is installed at the bottom of the fixed plate 104. When the position is adjusted to a suitable position, the push rod 302 at the bottom can be braked by the corresponding hydraulic rod 301 at the top. This allows the pressing end 303 at the bottom of the push rod 302 to press the circuit board.

[0029] The position moving assembly 4 includes a rotary motor 401, which is mounted on the top side of the worktable 101. A threaded rod 402 is mounted inside the rotary motor 401, and a threaded block 403 is mounted in the middle of the threaded rod 402. The threaded block 403 is mounted in the middle of the bottom of the moving plate 404. A rotary motor 405 is mounted on the top side of the moving plate 404, and a transmission device 406 is mounted on one side of the rotary motor 405. A threaded rod 407 is mounted inside the transmission device 406, and a threaded block 408 is mounted in the middle of the threaded rod 407. The threaded block 408 is mounted in the bottom of the clamping plate 409. In the position adjustment process, firstly, the rotary motor 401 rotates and brakes the threaded rod 402 at the end, which drives the threaded block 403 in the middle to move. Then, the movement of the threaded block 403 drives the top moving plate 404 to move synchronously. After that, the rotary motor 405 at the top of the moving plate 404 drives the transmission device 406 on one side, which drives the threaded rod 407 on one side, which in turn drives the threaded block 408 in the middle of the threaded rod 407 to move. The movement of the threaded block 408 then drives the top clamping plate 409 to move.

[0030] The adjusting clamping assembly 5 includes a pneumatic telescopic pump 501, which is installed at the top diagonal position of the clamping plate 409. A lifting curved rod 502 is installed on the top of the pneumatic telescopic pump 501, and a telescopic push rod 503 is installed at the end of the lifting curved rod 502. A limit slot 504 is installed at the end of the telescopic push rod 503. The circuit board is placed between the limit slots 504, and then pushed forward by the telescopic push rod 503 inside the lifting outer rod 502. This can achieve the clamping operation of the circuit board.

[0031] When using this device, first install the movable fixing component 2 at the bottom of the bracket assembly 1. This allows for convenient and effortless movement when needed. After moving to the corresponding position, it can be fixed using the movable fixing component 2. Then, the circuit board is positioned in the middle of the adjusting clamping component 5, and the position is adjusted using the position moving component 4. Finally, it is pressed using the pressing component 3. In use, first install the support frame 103 on the top of the workbench 101, and install the fixing plate 104 on the top of the support frame 103 to provide the installation conditions for the pressing component 3. After the bracket assembly 1 is installed, it is moved using the movable fixing component 2. During movement, the bottom-mounted moving wheels 202 are used to move it to the appropriate position. Then, the telescopic rod 203 is used for telescopic support. The circuit board is then installed in the adjusting clamping component 5. During installation, the circuit board is first placed between the limiting slots 504, and then... The telescopic push rod 503 inside the lifting outer rod 502 is pushed forward, thus clamping the circuit board. After the circuit board is fixed in place, the position can be adjusted by the position moving component 4. During position adjustment, the rotary motor 401 first rotates and brakes the threaded rod 402 at the end, which drives the threaded block 403 in the middle to move. Then, the movement of the threaded block 403 drives the top moving plate 404 to move synchronously. Finally, the top of the moving plate 404... The rotary motor 405 drives the transmission device 406 on one side, which in turn drives the threaded rod 407 on one side. This causes the threaded block 408 in the middle of the threaded rod 407 to move. The movement of the threaded block 408 causes the clamping plate 409 at the top to move. When the position is adjusted to a suitable position, the hydraulic rod 301 at the top can brake the push rod 302 at the bottom. This allows the extrusion end 303 at the bottom of the push rod 302 to extrude force on the circuit board.
