[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a quick alignment and assembly fixture for a rigid-flex plate provided by this utility model; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 The diagram shows a three-dimensional structure of the alignment and assembly fixture from a first-view perspective. Figure 4 for Figure 3 The enlarged schematic diagram of section B is shown below; Figure 5 for Figure 1 The diagram shows a three-dimensional structure of the alignment assembly fixture from a second perspective. Figure 6 for Figure 5 The enlarged schematic diagram of section C is shown. A rapid alignment and assembly fixture for a rigid-flex PCB includes: Mounting bracket 1, two movable components 2, pressing component 3, adjusting component 4, and fixing component 5; The two movable components 2 are respectively disposed on both sides of the surface of the mounting frame 1; The extrusion assembly 3 is disposed inside the mounting frame 1 and located between the two movable assemblies 2; The adjustment component 4 is disposed at the bottom of the mounting frame 1. The adjustment component 4 includes multiple mounting sleeves 41, multiple L-shaped threaded rods 42, an adjustment plate 43, and multiple threaded sleeves 44. The multiple mounting sleeves 41 are connected to the surface of the mounting frame 1. The multiple L-shaped threaded rods 42 are respectively disposed inside the multiple mounting sleeves 41. The adjustment plate 43 is connected between the multiple L-shaped threaded rods 42. The multiple threaded sleeves 44 are respectively threaded to both sides of the surface of the multiple L-shaped threaded rods 42. The fixing component 5 is disposed on the surface of the mounting bracket 1.

[0020] When the fixture height needs to be adjusted, rotate the threaded sleeve 44 to move it up and down along the L-shaped threaded rod 42. When the threaded sleeve 44 is turned upward, it pushes the mounting sleeve 41 upward, causing the adjusting plate 43 to rise; conversely, it lowers. By simultaneously adjusting multiple sets of threaded sleeves 44, the adjusting plate 43 can be kept horizontal, thereby meeting the assembly requirements of circuit boards of different specifications.

[0021] After placing the rigid-flex plate between the adjusting plate 43 and the fixed plate 51, push the movable block 22 to slide in the movable groove 21, so that the U-shaped mounting brackets 31 on both sides move closer to the circuit board. At this time, the pressing block 34 (with a silicone buffer layer on its surface) contacts the side of the circuit board. The disassembly block 32 is fixed by rotating the bolt 35, so that the pressing block 34 maintains lateral pressure on the circuit board. The spacing of the pressing block 34 can be adjusted by sliding the movable block 22 to adapt to circuit boards of different widths.

[0022] After the height of the adjusting plate 43 is determined, the rectangular block 52 of the fixing plate 51 is inserted into the rectangular sleeve 53 and the connecting bolt 54 is screwed in to fix it. The fixing plate 51 and the adjusting plate 43 form an upper and lower clamping surface, which limits the vertical direction of the soft and hard combination plate. The bottom surface of the fixing plate 51 is covered with an anti-slip rubber pad, which can increase friction and prevent the circuit board from moving up and down.

[0023] The fixing plate 51 is aligned with the rectangular sleeve 53 on the surface of the mounting bracket 1 by means of the rectangular block 52, and the connecting bolt 54 passes through the rectangular block 52 and the rectangular sleeve 53 to achieve fixation.

[0024] The extrusion block 34 can be replaced with extrusion blocks of different curvatures by removing bolts 35 to adapt to the shape of the transition area between rigid and flexible plates.

[0025] The movable component 2 includes a movable groove 21 and a movable block 22. The movable groove 21 is formed on the surface of the mounting bracket 1, and the movable block 22 is slidably connected to the interior of the movable groove 21.

[0026] The extrusion assembly 3 includes two U-shaped mounting brackets 31, two disassembly blocks 32, a fixing rod 33, multiple extrusion blocks 34, bolts 35, and a movable through slot 36. The two U-shaped mounting brackets 31 are respectively connected to opposite sides of the two movable blocks 22. The two disassembly blocks 32 are disposed inside the two U-shaped mounting brackets 31. The fixing rod 33 is connected between the two disassembly blocks 32. The multiple extrusion blocks 34 are respectively disposed on the surface of the fixing rod 33.

[0027] The bolt 35 is disposed between the U-shaped mounting bracket 31 and the disassembly block 32, and the movable through groove 36 is opened on one side inside the mounting bracket 1.

[0028] The fixing component 5 includes a fixing plate 51, a plurality of rectangular blocks 52, a plurality of rectangular sleeves 53 and a plurality of connecting bolts 54. The plurality of rectangular blocks 52 are respectively connected to the sides of the fixing plate 51, the plurality of rectangular sleeves 53 are respectively connected to the surface of the mounting bracket 1, and the plurality of connecting bolts 54 are respectively disposed between the plurality of rectangular blocks 52 and the plurality of rectangular sleeves 53.

[0029] A baffle 6 is connected to one side of the surface of the adjustment plate 43, and brackets 7 are connected to both sides of the bottom of the mounting bracket 1.

[0030] Compared with related technologies, the quick alignment and assembly fixture for rigid-flexible bonded plates provided by this utility model has the following advantages: This utility model provides a quick alignment and assembly fixture for a rigid-flex plate. Multiple mounting sleeves 41, multiple L-shaped threaded rods 42, an adjusting plate 43, and multiple threaded sleeves 44 are provided at the bottom of the mounting frame 1 to work with two movable components 2 and a pressing component 3. The size between the adjusting plate 43 and the fixed plate 51 can be adjusted according to the thickness of the rigid-flex plate, thereby achieving the applicability of the entire device.

[0031] Second Embodiment Please refer to the following: Figure 7 and Figure 8 Based on the first embodiment of this application, which provides a rapid alignment and assembly fixture for rigid-flex PCBs, the second embodiment of this application proposes another rapid alignment and assembly fixture for rigid-flex PCBs. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the separate implementation of the first embodiment.

[0032] Specifically, the second embodiment of this application provides a quick alignment and assembly fixture for a rigid-flex PCB, which differs in that a snap-fit ​​assembly fixture for a rigid-flex PCB is provided between the mounting frame 1 and the fixing plate 51. The snap-fit ​​assembly 8 includes a snap-fit ​​sleeve 81, a snap-fit ​​block 82, and a fixing bolt 83. The snap-fit ​​sleeve 81 is connected to the surface of the mounting frame 1, the snap-fit ​​block 82 is disposed between the fixing plate 51 and the snap-fit ​​sleeve 81, and the fixing bolt 83 is disposed between the snap-fit ​​sleeve 81 and the snap-fit ​​block 82.

[0033] Disassembly procedure: Loosen the retaining bolt 83, pull the snap-fit ​​block 82 out of the snap-fit ​​sleeve 81, and the retaining plate 51 can be removed. This process does not require complete disassembly of the connecting bolt 54, only loosening the retaining bolt 83 is needed.

[0034] Installation procedure: Align the snap-fit ​​block 82 with the snap-fit ​​sleeve 81 and insert it. Tighten the fixing bolt 83. Ensure the verticality of the fixing plate 51 after installation by adjusting the fit gap between the snap-fit ​​sleeve 81 and the snap-fit ​​block 82.

[0035] When replacing the fixing plate 51, if it is necessary to adapt to circuit boards of different thicknesses, the height of the adjusting plate 43 can be adjusted first by adjusting component 4, and then the corresponding fixing plate 51 can be quickly installed using the snap-fit ​​component 8 (for example, a thicker fixing plate can be used for thick plates). The positioning accuracy of the snap-fit ​​component is superimposed with the height accuracy of the adjusting component.

[0036] Compared with related technologies, the quick alignment and assembly fixture for rigid-flexible bonded plates provided by this utility model has the following advantages: This utility model provides a quick alignment and assembly fixture for a rigid-flex plate. A snap-fit ​​sleeve 81, a snap-fit ​​block 82, and a fixing bolt 83 are provided between the mounting frame 1 and the fixing plate 51 to facilitate convenient installation and disassembly between the fixing plate 51 and the mounting frame 1.
