Description

Technical Field

[0001] This application relates to the field of FPC processing, and in particular to a limiting device for FPC. Background Technology

[0002] FPC, or Flexible Printed Circuit Board, is widely used in consumer electronics, automotive electronics, and other fields due to its thinness, lightness, and flexibility. Development, a key step in FPC processing, involves using a chemical solution to dissolve the photoresist in the unexposed areas to form the circuit pattern.

[0003] In related technologies, the developing process typically uses a conveyor belt to continuously transport FPCs. To minimize the risk of indentations caused by roller pressure on thinner FPCs during transport, the FPCs are placed on a guide plate and secured with multiple high-temperature adhesive tapes.

[0004] However, in practical applications, the installation and disassembly of FPCs are quite troublesome because they are fixed by multiple high-temperature adhesive tapes, which affects the processing efficiency of FPCs. Therefore, improvements are needed. Utility Model Content

[0005] To facilitate the installation and removal of FPCs, this application provides a limiting device for FPCs.

[0006] The limiting device for FPC provided in this application adopts the following technical solution:

[0007] A limiting device for an FPC includes a guide plate, two first limiting plates, two second limiting plates, and two adjusting components; the two first limiting plates are disposed opposite each other on the upper side of the guide plate, and the two second limiting plates are disposed opposite each other on the upper side of the guide plate, and the two first limiting plates and the two second limiting plates are distributed in a rectangular shape.

[0008] Two adjustment components are respectively disposed on the two second limiting plates; each adjustment component includes a mounting plate, a mounting rod, a first spring, and a limiting nut; the mounting plate is disposed on the upper side of the guide plate, the mounting rod is movably inserted through the mounting plate and disposed on the side of the second limiting plate away from the first limiting plate, the first spring is disposed between the mounting plate and the second limiting plate to drive the second limiting plate closer to the first limiting plate, and the limiting nut is threadedly connected to the mounting rod and abuts against the side of the mounting plate away from the second limiting plate.

[0009] By adopting the above technical solution, in practical applications, the FPC is placed between two first limiting plates and two second limiting plates to achieve the limiting installation of the FPC. By pulling each mounting rod, each second limiting plate is moved away from each first limiting plate to facilitate the removal of the FPC, thus facilitating the installation and removal of the FPC and ensuring the processing efficiency of the FPC.

[0010] Furthermore, by rotating the limiting nut, the distance between each second limiting plate and each first limiting plate can be adjusted to improve the limiting effect on the FPC and make it applicable to FPCs of different sizes, thereby improving the applicability of the limiting device.

[0011] Preferably, the upper side of the guide plate has multiple through holes.

[0012] By adopting the above technical solution and setting multiple through holes, the chemical solution can quickly penetrate and flow out of the FPC after development, eliminating the need for manual cleaning and facilitating rapid reuse.

[0013] Preferably, the guide plate has two sliding grooves on its upper side, the sliding grooves are arranged along the length direction of the mounting rod, and each of the second limiting plates is slidably connected in each of the sliding grooves.

[0014] By adopting the above technical solution and setting two sliding grooves, the stability of the movement of the second limiting plate is improved, so as to ensure the accurate position of the second limiting plate after sliding.

[0015] Preferably, the limiting nut is a wing nut.

[0016] By adopting the above technical solution, and by setting the limit nut as a wing nut, it is easier to rotate the limit nut.

[0017] Preferably, the limiting device further includes two rubber pads, each of which is disposed on the side of each second limiting plate close to each first limiting plate.

[0018] By adopting the above technical solution, two rubber pads are set to replace the second limiting plate in contact with the FPC, so as to avoid damage to the FPC from contact with the second limiting plate.

[0019] Preferably, the limiting device further includes a connecting assembly, the connecting assembly including a connecting plate, the connecting plate being disposed at one end of the two mounting rods away from the second limiting plate.

[0020] By adopting the above technical solution, by setting a connecting plate and pulling the connecting plate, the two mounting rods can be moved synchronously, so that the two second limiting plates can move away from the corresponding first limiting plates synchronously, thereby further facilitating the disassembly of the FPC.

[0021] Preferably, the connecting plate is detachably connected to the two mounting rods.

[0022] By adopting the above technical solution, a connecting plate is detachably connected to two mounting rods to facilitate the installation and disassembly of the adjustment components.

[0023] Preferably, the connecting assembly further includes two limiting members, each including a limiting rod and a second spring. The two mounting rods are movably inserted through the connecting plate, the limiting rod is movably inserted through the connecting plate, and the second spring is disposed between the limiting rod and the connecting plate to drive the limiting rod to pass through the mounting rod.

[0024] By adopting the above technical solution, and by setting a limit rod and a second spring, a detachable connection between the connecting plate and the mounting rod can be achieved. The structure is simple and the operation is convenient.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The FPC is placed between two first limiting plates and two second limiting plates to achieve the limiting installation of the FPC. By pulling each mounting rod, each second limiting plate is moved away from each first limiting plate to facilitate the removal of the FPC, thus facilitating the installation and removal of the FPC and ensuring the processing efficiency of the FPC.

[0027] 2. By rotating the limiting nut, the distance between each second limiting plate and each first limiting plate can be adjusted to improve the limiting effect on the FPC and make it applicable to FPCs of different sizes, thereby improving the applicability of the limiting device;

[0028] 3. By setting a connecting plate, pulling the connecting plate can drive the two mounting rods to move synchronously, so that the two second limit plates can move away from the corresponding first limit plates at the same time, thereby further facilitating the disassembly of the FPC.

[0032] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0033] This application discloses a limiting device for FPC.

[0034] Reference Figure 1 The limiting device includes a guide plate 1, two first limiting plates 2, two second limiting plates 3, and two adjusting components 4. The guide plate 1 is rectangular, and the two first limiting plates 2 and the two second limiting plates 3 are right-angled plates. The two first limiting plates 2 are fixedly connected to the upper side of the guide plate 1, and are positioned opposite each other and spaced apart along the width direction of the guide plate 1. The two second limiting plates 3 are located on the upper side of the guide plate 1, and are positioned opposite each other and spaced apart along the width direction of the guide plate 1. The two first limiting plates 2 and the two second limiting plates 3 are rectangularly distributed to form a placement groove (not marked in the figure) for placing the FPC.

[0035] Two adjusting components 4 are respectively positioned on the two second limiting plates 3. Specifically, each adjusting component 4 includes a mounting plate 41, a mounting rod 42, a first spring 43, and a limiting nut 44. The mounting plate 41 is fixedly connected to the upper side of the guide plate 1 and is located on the side of the second limiting plate 3 away from the first limiting plate 2. The mounting rod 42 is movably inserted through the mounting plate 41 and one end is fixedly connected to the side of the second limiting plate 3 away from the first limiting plate 2. One end of the first spring 43 elastically abuts against the mounting plate 41, and the other end elastically abuts against the second limiting plate 3 to drive the second limiting plate 3 closer to the first limiting plate 2. The limiting nut 44 is threadedly connected to the mounting rod 42 and abuts against the side of the mounting plate 41 away from the second limiting plate 3 to restrict the movement of the second limiting plate 3.

[0036] In practical applications, the FPC is placed in the placement groove formed between the two first limiting plates 2 and the two second limiting plates 3 to achieve the limiting installation of the FPC. By pulling each mounting rod 42, each second limiting plate 3 is moved away from each first limiting plate 2, so that the FPC can be removed, which facilitates the disassembly of the FPC. This facilitates the installation and disassembly of the FPC and ensures the processing efficiency of the FPC.

[0037] By rotating the limiting nut 44, the position between the limiting nut 44 and the mounting rod 42 is adjusted, thereby adjusting the distance between each second limiting plate 3 and each first limiting plate 2. This improves the limiting effect on the FPC and makes it applicable to FPCs of different sizes, thus improving the applicability of the limiting device.

[0038] In some embodiments, the upper side of the guide plate 1 is provided with a plurality of through holes 11, which are arranged through the entire plate. After the FPC is processed by developing, the chemical solution can quickly penetrate and flow out through the plurality of through holes 11 without the need for manual cleaning, so as to facilitate the next use quickly.

[0039] In some embodiments, two sliding grooves 12 are provided on the upper side of the guide plate 1. The two sliding grooves 12 are arranged along the width direction of the guide plate 1, and the length direction of the sliding grooves 12 is parallel to the length direction of the mounting rod 42, so that each second limiting plate 3 is slidably limited in each sliding groove 12, so as to ensure that the second limiting plate 3 slides along the length direction of the mounting rod 42, thereby improving the stability of the movement of the second limiting plate 3, and ensuring that the position of the second limiting plate 3 after sliding is accurate, so as to accurately limit the FPC.

[0040] In some embodiments, the limiting nut 44 is a wing nut to facilitate the rotation of the limiting nut 44, thereby facilitating the adjustment of the distance between each second limiting plate 3 and each first limiting plate 2.

[0041] In some embodiments, the limiting device further includes two rubber pads 5, each rubber pad 5 being fixedly connected to the side of each second limiting plate 3 near each first limiting plate 2, so as to replace the second limiting plate 3 in contacting the FPC, thereby minimizing the possibility of the FPC being damaged by contact with the second limiting plate 3, and thus ensuring the processing effect of the FPC.

[0042] In some embodiments, the limiting device further includes a connecting component 6. Specifically, the connecting component 6 includes a connecting plate 61, which is installed on the end of the two mounting rods 42 away from the second limiting plate 3. By applying force through the multiple connecting plates 61, the two mounting rods 42 can be moved synchronously, so that the two second limiting plates 3 can be moved away from the corresponding first limiting plate 2 synchronously, thereby further facilitating the disassembly of the FPC.

[0043] Reference Figure 1 and Figure 2 In some embodiments, the connecting plate 61 is detachably connected to the two mounting rods 42. First, the connecting plate 61 is detached from the two mounting rods 42, and then the limiting nut 44 is rotated so that the limiting nut 44 is disengaged from the mounting rod 42. At this time, the mounting rod 42 can be detached from the mounting plate 41 to realize the disassembly of the adjustment component 4 and facilitate the assembly of the adjustment component 4, thereby facilitating the installation and disassembly of the adjustment component 4.

[0044] In some embodiments, the connecting assembly 6 further includes two limiting members 62, which are respectively connected to two mounting rods 42. Specifically, each limiting member 62 includes a limiting rod 621 and a second spring 622. The two mounting rods 42 are movably inserted through the connecting plate 61, and the limiting rod 621 is movably inserted through the connecting plate 61. One end of the second spring 622 is fixedly connected to the limiting rod 621, and the other end is fixedly connected to the connecting plate 61, so as to drive the limiting rod 621 to pass through the mounting rod 42, thereby fixing the connecting plate 61 and the mounting rod 42. In use, by pulling the limiting rod 621 to disengage it from the mounting rod 42, and then moving the connecting plate 61, the connecting plate 61 and the mounting rod 42 can be disassembled. The structure is simple and the operation is convenient.

[0045] The implementation principle of this embodiment is as follows: In practical applications, the FPC is placed in the placement groove formed between the two first limiting plates 2 and the two second limiting plates 3, which can realize the limiting installation of the FPC. By pulling each mounting rod 42, each second limiting plate 3 is moved away from each first limiting plate 2, so as to remove the FPC and facilitate the disassembly of the FPC. This facilitates the installation and disassembly of the FPC and ensures the processing efficiency of the FPC.

[0046] By rotating the limiting nut 44, the position between the limiting nut 44 and the mounting rod 42 is adjusted, thereby adjusting the distance between each second limiting plate 3 and each first limiting plate 2. This improves the limiting effect on the FPC and makes it applicable to FPCs of different sizes, thus improving the applicability of the limiting device.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
