[0017] Beneficial effects of the utility model:
[0018] 1. The positioning structure for improving the stability of the printed circuit board is provided with a driving component, which includes a fixed ring, a telescopic rod, a rotating ring, a connecting plate and other elements. Through the coordinated action of these components, the horizontal movement of the positioning component is realized. The telescopic rod contacts the bottom surface of the circuit board through the contact plate, driving the movement of the positioning component to ensure the accurate positioning of the circuit board in the horizontal direction. When installing and positioning the circuit board, the interaction between the threaded sliding groove of the telescopic rod and the positioning block, and the coordinated movement of the connecting plate and the connecting rod are realized to achieve the synchronous approach of the two moving blocks, thereby clamping the circuit board, so that the system can adapt to the sizes and shapes of different circuit boards, and improve the flexibility and applicability of clamping. The rotating ring enables the vertical movement of the telescopic rod to be converted into the horizontal movement of the connecting plate and the connecting rod, thereby driving the two moving blocks to approach each other. This conversion mechanism ensures the stability of the circuit board during the positioning and clamping process, and avoids the instability caused by uneven driving. The circuit board is placed on the contact plate by its own weight, and the positioning components on both sides are gradually driven to approach each other under the action of gravity, so as to achieve the effect of adapting to different circuit boards.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0031] like Figures 1 to 6 As shown, the positioning structure for improving the stability of the printed circuit board comprises: a positioning plate 1, two moving blocks 3 are slidably installed on both sides of the bottom surface of the positioning plate 1, the lengths of the two moving blocks 3 are greater than the width of the positioning plate 1, and fixed blocks 5 are fixedly installed on both sides of the two moving blocks 3; a positioning assembly, which is fixedly installed above the four fixed blocks 5, and the positioning assembly is used to locate and fix the position of the circuit board; a driving assembly, which is arranged in the middle of the positioning plate 1, and the driving assembly is used to drive the positioning assembly to move horizontally for positioning, wherein two groups of slide rails 2 are respectively arranged on the bottom surface of the positioning plate 1, and each group of slide rails 2 has two, and sliders 4 adapted to the slide rails 2 are respectively arranged on both sides of the top surface of the moving block 3, and the positioning plate 1 is arranged in a "convex" shape to limit the sliding stroke of the moving block 3;
[0032] The positioning plate 1 has a "convex" shape. Through this arrangement, the sliding stroke of the moving block 3 is limited. When the moving block 3 slides, the slider 4 slides on the slide rail 2, driving the moving block 3 to slide under the positioning plate 1, ensuring the accuracy and stability of positioning. The length of the moving block 3 is designed to be greater than the width of the positioning plate 1, providing good support and stability for the circuit board, and effectively preventing shaking during the positioning process. On this basis, the fixed blocks 5 are fixedly installed on both sides of the moving block 3, further ensuring the stability of the position of the moving block 3 relative to the positioning plate 1. The positioning assembly is installed above the fixed block 5, connected to the moving block 3 and the positioning plate 1, and is used to reliably locate and fix the position of the circuit board. At the same time, the driving assembly is arranged in the middle of the positioning plate 1, responsible for horizontally moving the positioning assembly to ensure the smoothness of the entire positioning process.
[0033] like Figure 1 , Figure 6 As shown, the positioning assembly includes a fixed sleeve 6 fixedly mounted on the fixed block 5, a butterfly block 7 rotatably mounted above the fixed sleeve 6, and a first positioning wheel 8 and a second positioning wheel 9 rotatably mounted on the butterfly block 7, respectively. The first positioning wheel 8 and the second positioning wheel 9 are respectively located on both sides above the butterfly block 7 and are arranged diagonally. The fixed block 5 is hollow, and the fixed sleeve 6 passes through the top of the fixed block 5 and is fixedly mounted inside the fixed block 5. The butterfly block 7 is butterfly-shaped, and the diameter of the first positioning wheel 8 is set to twice that of the second positioning wheel 9.
[0034] The hollow setting of the fixed block 5 and the fixing sleeve 6 that passes through the top of the fixed block 5 and is installed inside it provide a more stable support structure, enhance the stability of the entire positioning assembly, and ensure that the fixed block 5 is firmly connected with the moving block 3. The butterfly setting of the butterfly block 7 and the installation of the first positioning wheel 8 and the second positioning wheel 9 thereon enable the positioning assembly to achieve more complex rotational movement, increase the flexibility of the circuit board during the positioning process, and enable the positioning assembly to more accurately adjust the angle and position of the circuit board. The diagonal setting of the first positioning wheel 8 and the second positioning wheel 9, and the fact that the diameter of the first positioning wheel 8 is twice that of the second positioning wheel 9, enable more precise adjustments during the rotational movement, improve the positioning accuracy of the circuit board, and ensure the accuracy of positioning.
[0035] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the driving assembly includes a fixed ring 10 fixedly installed in the middle of the positioning plate 1, a telescopic rod 11 movably installed in the middle of the fixed ring 10, a rotating ring 15 sleeved under the telescopic rod 11 and the rotating ring 15 is rotatably connected to the telescopic rod 11, and a connecting plate 16 rotatably installed on both sides of the rotating ring 15. The upper end of the telescopic rod 11 is fixedly connected with a contact plate 12 for contacting the bottom surface of the circuit board for driving. The upper end of the fixed ring 10 is also provided with a plurality of positioning rods 13 arranged in a circle, and the positioning rods 13 penetrate the fixed ring 10. The outer surface of the positioning rod 13 between the fixed ring 10 and the contact plate 12 is sleeved with a reset spring 14. The lower end of the telescopic rod 11 is fixedly connected with a contact plate 12 for contacting the bottom surface of the circuit board for driving. A positioning groove 18 is provided on the side, and a threaded sliding groove 19 is also provided on the bottom of the telescopic rod 11. The sliding groove 19 is connected to the positioning groove 18. A positioning block 20 adapted to the sliding groove 19 is provided on the inner side of the rotating ring 15, and the positioning block 20 is slidably installed inside the sliding groove 19. A connecting rod 17 is also rotatably installed on the bottom surface of the two moving blocks 3. The connecting plates 16 are both arranged in an "L" shape, and the sides of the two connecting plates 16 away from the rotating ring 15 are rotatably connected to the other end of the connecting rod 17. Three pads 21 are respectively provided on the top triangle of the contact plate 12. The three pads 21 are respectively located above the three positioning rods 13, and the pads 21 are rubber;
[0036] When installing and positioning the circuit board, the circuit board is placed on the contact plate 12 above the telescopic rod 11, and the telescopic rod 11 is driven downward by pressing the contact plate 12, and the positioning rod 13 is driven to slide downward at the same time, and the reset spring 14 is squeezed. During the downward movement of the telescopic rod 11, the positioning block 20 is pushed to move in the sliding groove 19 through the threaded sliding groove 19 at the bottom of the telescopic rod 11. At this time, the downward force of the telescopic rod 11 is converted into the rotational force of the rotating ring 15, and the rotating ring 15 will rotate a certain angle to drive the connecting plates 16 on both sides to rotate. When the connecting moving blocks 3 approach each other, the positioning components on both sides will be driven to approach each other to position and clamp the circuit board, so as to achieve good stability. The circuit board is placed on the contact plate 12 by its own weight, and the positioning components on both sides are gradually driven to approach each other under the action of gravity, so as to achieve the effect of adapting to different circuit boards.
