[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1 Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a processing device for FPC circuit boards. The processing device for FPC circuit boards includes a fixing component 2. Through the fixing component 2 and the protective component 3, the fixing component 2 realizes the automatic triggering of the fixing process after the FPC circuit board is placed, eliminating the need for tedious manual operation, shortening the processing cycle, and improving production efficiency. Through the cooperation of the protective component 3, the protective enclosure 32 is automatically raised while fixing the circuit board, forming a protective barrier, effectively preventing accidental contact of the circuit board with the outside world, reducing the risk of circuit board displacement and component damage, reducing welding defects, and improving the product qualification rate.

[0028] The main structure 1 includes an operating table 11, with supports 12 fixedly connected to both sides of the bottom of the operating table 11. A placement platform 13 is embedded in the top of the operating table 11, and a through groove 14 is formed in the top of the placement platform 13. A pressure plate 15 is slidably connected to the inner cavity of the through groove 14, and the top of the pressure plate 15 passes through the through groove 14 and extends outside the through groove 14. A welding machine 16 is fixedly connected to one side of the top of the operating table 11; and... The fixing component 2 includes fixing plates 21 disposed on both sides of the top of the operating table 11, connecting electrodes 22 fixedly connected to the bottom of the pressure plate 15, electrode plates 23 fixedly connected to the bottom of the inner cavity of the through groove 14, cylinder 24 fixedly connected to the bottom of the placement table 13 and cooperating with the electrode plates 23, bending drive plate 25 fixedly connected to the bottom of the cylinder 24, connecting plates 26 fixedly connected to both sides of the bottom of the bending drive plate 25, first toothed plate 27 fixedly connected to the bottom of the connecting plate 26, and the top of the first toothed plate 27 penetrating the operating table 11 and connected to the fixing plate 21. The protective component 3 includes a trigger 31 disposed on one side of the first toothed plate 27, and a protective enclosure 32 is disposed on the top of the trigger 31.

[0029] The operating table 11 in the main structure 1 provides an operating platform for the entire processing. The bracket 12 provides stable support. The placement table 13 is used to support the FPC circuit board. The through slot 14 cooperates with the pressure plate 15. After the FPC circuit board is placed, the pressure plate 15 slides into the through slot 14 under force, causing the connecting electrode 22 and the electrode sheet 23 to contact, thereby triggering the operation of the subsequent mechanism. The welding machine 16, as the core welding component, is used to complete the welding task of the circuit board. The fixing component 2 achieves automatic fixing of the circuit board through the coordination of the fixing plate 21, connecting electrode 22, electrode sheet 23, cylinder 24, bending drive plate 25, connecting plate 26 and first toothed plate 27, etc., which solves the problem of complex traditional manual or electric fixing operations. The trigger 31 in the protective component 3 cooperates with the protective enclosure 32, which can automatically raise the protective enclosure 32 while fixing the circuit board, preventing accidental contact with the circuit board from the outside, and comprehensively ensuring the stability and safety of the FPC circuit board processing process.

[0030] The welding machine 16, connecting electrode 22, electrode sheet 23 and cylinder 24 are all existing technologies, which are clearly known to those skilled in the art and will not be described in detail.

[0031] Example 2 Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, the trigger 31 includes a gear 31-1 meshing with the side of the first toothed plate 27 away from the cylinder 24, a second toothed plate 31-2 meshing with the side of the gear 31-1 away from the cylinder 24, a support frame 31-3 fixedly connected to the top of the second toothed plate 31-2, and the top of the support frame 31-3 fixedly connected to the protective enclosure 32.

[0033] The gear 31-1 acts as a transmission mechanism, converting the linear motion of the first toothed plate 27 into its own rotation, which in turn drives the second toothed plate 31-2, which meshes with it, to move linearly. The second toothed plate 31-2 is connected to the protective enclosure 32 through the support frame 31-3, so that the protective enclosure 32 can rise and fall accordingly as the first toothed plate 27 moves, thus realizing the protective triggering function.

[0034] Specifically, the top of the protective enclosure 32 extends through the operating table 11 and is slidably connected to the operating table 11.

[0035] The top of the protective enclosure 32 is slidably connected to the operating table 11. This design ensures the stability of the protective enclosure 32 during the rising and falling process, preventing it from shifting or getting stuck during movement, thus enabling it to better perform its protective function and effectively prevent accidental contact with the circuit board from the outside.

[0036] Specifically, an arc-shaped guide plate 32-1 is slidably connected to the surface of the protective enclosure 32, and the bottom of the arc-shaped guide plate 32-1 is fixedly connected to the operating table 11.

[0037] The arc-shaped guide plate 32-1 is slidably connected to the surface of the protective enclosure 32 and its bottom is fixed on the operating table 11. It provides guidance for the lifting and lowering of the protective enclosure 32, further ensuring the accuracy and smoothness of the movement of the protective enclosure 32 and ensuring the effective execution of the protective action.

[0038] Specifically, a rotating shaft 31-4 is fixedly connected to the inner cavity of gear 31-1, and a limiting plate 31-5 is rotatably connected to both sides of the rotating shaft 31-4. The top of the limiting plate 31-5 is fixedly connected to the operating table 11.

[0039] The shaft 31-4 inside the gear 31-1 is rotatably connected to two sides of the limiting plate 31-5. The top of the limiting plate 31-5 is fixed to the operating table 11. This structure limits and supports the gear 31-1, preventing the gear 31-1 from undergoing axial displacement during rotation, ensuring the stability of its transmission, and thus ensuring the overall reliability of the trigger 31.

[0040] Specifically, a slider 31-6 is fixedly connected to the side of the second toothed plate 31-2 away from the cylinder 24, and a groove 31-7 is provided on the side of the bracket 12 near the slider 31-6, which cooperates with the slider 31-6.

[0041] The slider 31-6 fixed on one side of the second toothed plate 31-2 cooperates with the groove 31-7 opened on the bracket 12 to limit the second toothed plate 31-2, so that it maintains the accuracy of direction during linear movement, avoids shaking or deviation, and ensures that the protective enclosure 32 can rise and fall stably.

[0042] Specifically, a first spring 31-8 is fixedly connected to the top of the slider 31-6, and the top of the first spring 31-8 is fixedly connected to the inner cavity of the slide groove 31-7.

[0043] When the protective enclosure 32 rises, the second toothed plate 31-2 drives the slider 31-6 to move upward in the groove 31-7, and the first spring 31-8 is compressed and stores elastic potential energy; when the protective enclosure 32 falls back to its original position, the first spring 31-8 releases elastic potential energy, providing a downward auxiliary restoring force for the slider 31-6.

[0044] The first spring 31-8 is existing technology. Its specifications and elastic coefficient and other parameters can be selected according to the actual situation. This is existing technology, and those skilled in the art can clearly understand it.

[0045] Specifically, a second spring 15-1 is fixedly connected to the bottom of the pressure plate 15, and the bottom of the second spring 15-1 is fixedly connected to the inner cavity of the through groove 14.

[0046] The second spring 15-1 provides a restoring force to the pressure plate 15, so that the pressure plate 15 can be smoothly restored to its initial position after welding is completed.

[0047] The second spring 15-1 is existing technology. Its specifications and elastic coefficient and other parameters can be selected according to the actual situation. This is existing technology, and those skilled in the art can clearly understand it.

[0048] Specifically, there are multiple sets of the second spring 15-1, which are evenly distributed at the bottom of the pressure plate 15.

[0049] Multiple sets of second springs 15-1 evenly distributed at the bottom of the pressure plate 15 make the pressure plate 15 more stable when sliding under force, ensuring reliable contact between the connecting electrode 22 and the electrode plate 23, and providing stable conditions for triggering fixing and protection actions.

[0050] Specifically, both sides of the pressure plate 15 are provided with mating grooves 15-2, and both sides of the inner cavity of the through groove 14 are fixedly connected with mating blocks 15-3.

[0051] The mating grooves 15-2 on both sides of the pressure plate 15 and the mating blocks 15-3 on both sides of the inner cavity of the through groove 14 provide precise guidance and positioning for the sliding of the pressure plate 15 in the through groove 14, ensuring accurate movement of the pressure plate 15, so that the connecting electrode 22 and the electrode plate 23 can reliably contact each other and smoothly trigger subsequent fixing and protection actions.

[0052] When this equipment is working, the FPC circuit board is first placed on the placement platform 13. The weight of the circuit board causes the pressure plate 15 to slide into the through groove 14. The connecting electrode 22 at the bottom of the pressure plate 15 contacts the electrode piece 23 at the bottom of the cavity of the through groove 14, forming an electrical connection, thereby opening the cylinder 24 and completing the automatic fixing triggering step. After the cylinder 24 is started, it pushes the bending drive plate 25 to move downward. The bending drive plate 25 drives the connecting plate 26 and the first toothed plate 27 to move downward synchronously. The first toothed plate 27 passes through the operating table 11 and connects with the fixing plate 21, driving the fixing plate 21 to move and automatically clamping and fixing the FPC circuit board, which solves the problem of complicated fixing operation of traditional fixtures. While the first toothed plate 27 moves, its side away from the cylinder 24 meshes with the gear 31-1, driving the gear 31-1 to rotate. The gear 31-1 rotates stably under the support and limitation of the limiting plate 31-5 via the rotating shaft 31-4, driving the second toothed plate 31-2, which meshes with it, to move upward. Under the limiting action of the slider 31-6 and the slide groove 31-7, the second toothed plate 31-2 drives the protective enclosure 32 to rise through the support frame 31-3. The protective enclosure 32 rises smoothly under the guidance of the arc-shaped guide plate 32-1, forming a protection around the FPC circuit board, preventing accidental contact with the circuit board from the outside, and making up for the lack of protection in the existing fixtures. When welding is completed, cylinder 24 reverses its movement, causing the first toothed plate 27 to rise. All components move in the opposite order. The first spring 31-8 releases its elastic potential energy to assist the slider 31-6 in resetting, causing the protective enclosure 32 to descend. The pressure plate 15 resets under the action of the second spring 15-1, and the fixing plate 21 loosens the circuit board, making it easier to remove the processed FPC circuit board.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
