Technical Field

[0001] This utility model relates to the field of FPC technology, specifically to a device for quickly holding and fixing an FPC. 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. During module assembly, mounting fixtures are frequently used. Traditional mounting fixture structures can only achieve planar positioning, and sometimes the FPC will tilt, resulting in more wasted time during mounting, increased operator fatigue, and lower product yield. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a device for quickly holding and fixing FPCs, which has the advantages of easy installation and fixing of FPCs, saving time and effort. It solves the problem that the existing mounting fixture structure can only achieve planar positioning, and sometimes the FPC will tilt up, causing cumbersome, time-consuming and labor-intensive operation.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A device for quickly gripping and fixing an FPC includes a support mechanism for supporting the entire device. The support mechanism includes a base plate and a fixing mechanism for effectively fixing the FPC. A connecting mechanism for tightly connecting the device is provided between the support mechanism and the fixing mechanism. The fixing mechanism includes multiple positioning rods fixedly connected to the base plate. A mounting fixture is engaged with the base plate by the multiple positioning rods. The base plate has a slot, and two circular holes are formed in the slot. The mounting fixture has a mounting groove for placing the FPC and multiple vent holes. A vacuum generator is installed at the bottom of the base plate, and the vacuum generator is equipped with a suction pipe and an exhaust pipe that are respectively connected to the two circular holes.

[0005] Preferably, the connecting mechanism includes two connecting blocks fixedly connected to both sides of the base plate. Two fixed frames are rotatably connected to the opposite side of the two connecting blocks on the same side. A set of sliding grooves is provided in each of the two fixed frames.

[0008] Preferably, the mounting fixture has modules mounted on it via multiple positioning rods, and the FPC is bonded to the modules via adhesive backing.

[0009] Preferably, the bottom of the base plate is fixedly connected to two support plates.

[0010] By employing the above technical solution, this utility model provides a device for quickly adsorbing and fixing FPC, which has at least the following beneficial effects: 1. This utility model enables the device to adsorb and fix FPC by setting a fixing mechanism. The mounting fixture is installed on the base plate by the positioning rod.

[0014] 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.

[0015] When assembling modules, mounting fixtures are often used. Traditional mounting fixture structures can only achieve planar positioning, and sometimes the FPC will tilt up. This leads to more wasted time during mounting, more fatigue for operators, and lower product yield. Therefore, a new structure needs to be designed to replace the previous structure and achieve cost reduction and efficiency improvement. When assembling modules on the production line, FPCs need to be attached to the module one by one without any jamming. The following describes some embodiments of this utility model with reference to the accompanying drawings, providing a device for quickly holding and fixing FPCs.

[0016] Example 1: Combination Figures 1-3 As shown, a device for quickly adsorbing and fixing FPC is proposed. A support mechanism 1 is set to support the whole device. A fixing mechanism 2 is set on the support mechanism 1 to effectively fix the FPC. A connecting mechanism 3 is set between the support mechanism 1 and the fixing mechanism 2. The connecting mechanism 3 makes the base plate 102 and the mounting fixture 201 tightly connected, ensuring the adsorption and fixing effect of the FPC.

[0017] To adsorb and fix the FPC, a fixing mechanism 2 is proposed. Multiple positioning rods 202 are fixedly connected to a base plate 102. A mounting fixture 201 is clamped onto the base plate 102 via the positioning rods 202. A slot 203 is formed in the base plate 102, and a sealing strip 205 is installed at the edge of the slot 203. Two circular holes 204 are formed in the slot 203 on the base plate 102. The mounting fixture 201 has a mounting groove for placing the FPC, and multiple ventilation holes 206 are formed in the mounting groove. A vacuum generator 207 is installed at the bottom of the base plate 102. The vacuum generator 207 is equipped with a suction pipe 208 and an exhaust pipe 209, which are respectively connected to the two circular holes 204. The fixture 201 is mounted with modules via multiple positioning rods 202. The FPC is bonded to the modules with adhesive. The mounting fixture 201 is mounted on the base plate 102 via the multiple positioning rods 202. The vacuum generator 207 is activated, and a vacuum environment is gradually formed in the slot 203 through the suction pipe 208 and the exhaust pipe 209. The sealing strip 205 ensures the adsorption and fixation effect of the FPC. At this time, the FPC is placed in the mounting slot area, and the FPC is adsorbed and fixed through multiple vents 206. The release film is torn off, and the modules are positioned by the positioning rods 202 on the mounting fixture 201. The FPC and the modules are bonded with adhesive, thereby completing the assembly of the modules and improving the fixation effect of the FPC.

[0018] Example 2: Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the problem that in the prior art, when assembling modules, mounting fixtures are often used. The traditional mounting fixture structure can only achieve planar positioning. Sometimes the FPC will be tilted up, which makes the mounting process time-consuming and laborious. However, in order to avoid air leakage at the connection between the mounting fixture 201 and the base plate 102, it is necessary to further install a seal between the mounting fixture 201 and the base plate 102.

[0019] To ensure a proper seal between the mounting fixture 201 and the base plate 102, combined with Figure 1 and Figure 4As shown, a connecting mechanism 3 is proposed. Two connecting blocks 301 are fixedly connected to each side of the base plate 102. Two fixed frames 302 are rotatably connected to the opposite side of the two connecting blocks 301 on the same side. Each fixed frame 302 has a set of sliding grooves 303. A set of springs 304 is fixedly connected to each set of fixed frames 302. A fixed block 305 is fixedly connected to one end of each set of springs 304. Sliding blocks 306, which slidably connect to each set of sliding grooves 303, are fixedly connected to both sides of the fixed blocks 305. Limiting frames 307 are fixedly connected between the fixed blocks 305 on the same side. Sealing gaskets are installed at the bottom of each of the two limiting frames 307. Both sides of the mounting fixture 201 are fixedly connected to limiting blocks 308. When the bottom of the limiting frame 307 contacts the top of the limiting block 308, multiple sets of springs 304 are in a contracted state. Under the action of the springs 304, the limiting frame 307 is pulled, causing the fixing block 305 to slide in the slide groove 303 via the slider 306. At this time, the limiting frame 307 is rotated to move it above the limiting block 308. Then the limiting frame 307 is released, and under the contraction of the springs 304, the limiting frame 307 and the limiting block 308 are connected in contact, thereby completing the fixation of the limiting frame 307 and ensuring the sealing effect between the base plate 102 and the mounting fixture 201 to prevent air leakage.

[0020] To support the entire device, a support mechanism 1 is proposed. A base plate 102 is set, and two support plates 101 are fixedly connected to the bottom of the base plate 102. The stability of the device is ensured by the two support plates 101. The FPC and the module are accurately bonded to the mounting fixture 201 through the base plate 102, and the tolerance of the assembled product also meets the specified range.

[0021] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
