Description

Technical Field

[0001] This utility model relates to the field of circuit board testing technology, and in particular to a flip-type circuit board precision testing and positioning device. Background Technology

[0002] A circuit board is a carrier used to connect and support electronic components. It fixes electronic components and realizes electrical connections through conductive paths and pads. It is the core component for realizing circuit functions in modern electronic devices.

[0003] Traditional circuit board positioning methods often rely on manual control to manipulate the lateral movement of the worktable. When double-sided inspection of the component and solder sides of the circuit board is required, most existing positioning devices have a fixed structure, necessitating the removal of the circuit board and repeated clamping. This inconvenient operation process reduces the flexibility of the device.

[0004] Therefore, this utility model provides a flip-type circuit board precision detection and positioning device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a flip-type circuit board precision detection and positioning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flip-type circuit board precision detection and positioning device, including a base plate;

[0007] A flipping assembly includes a support plate slidably connected to a base plate, a slider is fixedly connected to one side of the support plate, a limit plate is fixedly connected to the side of the slider away from the support plate, a toothed column is fixedly connected to one side of the limit plate, a rotating wheel is provided on one side of the limit plate, and teeth are fixedly connected to the outer side of the rotating wheel.

[0008] The limiting component includes a support frame fixedly connected to both sides of the top of the base plate. A rotating shaft is rotatably connected inside the support frame. A ratchet is fixedly connected to the outside of the rotating shaft. A pawl is rotatably connected to the outside of the support frame. Extension rods are fixedly connected to both ends of the outside of the rotating shaft. An installation component is fixedly connected to the outside of the limiting component.

[0009] In a preferred embodiment, the mounting assembly includes a mounting block fixedly connected to the extension rod, the mounting block having a threaded post internally threadedly connected to it, and a locking block fixedly connected to the bottom end of the threaded post.

[0010] In a preferred embodiment, support blocks are fixedly connected to both ends of the wheel, and the outer side of the support block is in contact with the inside of the limiting plate.

[0011] In a preferred embodiment, a handle is fixedly connected to one end of the limiting plate.

[0012] In a preferred embodiment, the toothed column and the toothed teeth are meshingly connected, and the ratchet and the pawl are meshingly connected.

[0013] In a preferred embodiment, a second groove is provided on one side of the top of the base plate, and a second slider is slidably connected to the mounting assembly.

[0014] In a preferred embodiment, the top end of the second slide is fixedly connected to the bottom end of the support plate.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] This invention allows the mounting component to be flipped by pushing a handle and causing a slider to slide on a support plate. The teeth on the limiting plate mesh with the slider, causing the rotating wheel to rotate and transmitting the rotational force to the extension rod. Simultaneously, the support block engages with the protruding portion of the inner wall of the limiting plate, and the pawl engages with the ratchet wheel for positioning. When flipping is needed again, pulling up the pawl releases the engagement. When installing the circuit board, rotating the threaded column moves the locking block up and down, fixing the circuit board between the mounting block and the locking block. This design, using a handle and gear transmission structure, allows for flipping without removing the circuit board, simplifying the operation. Furthermore, the pawl and ratchet engagement design ensures stable positioning of the circuit board after flipping, avoiding detection errors caused by shaking. Additionally, the design can be adjusted according to the thickness and width of the circuit board during installation, thus accommodating circuit boards of different specifications.

[0028] 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.

[0029] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a flip-type circuit board precision detection and positioning device, including a base plate 1, a sliding groove 5 is provided on one side of the top of the base plate 1, and a slider 6 is slidably connected on the mounting assembly 4;

[0030] The flipping assembly 2 includes a support plate 21 slidably connected to the base plate 1. The top end of the slide groove 5 is fixedly connected to the bottom end of the support plate 21. A slider 22 is fixedly connected to one side of the support plate 21. A limiting plate 23 is fixedly connected to the side of the slider 22 away from the support plate 21. A toothed column 24 is fixedly connected to one side of the limiting plate 23. A rotating wheel 25 is provided on one side of the limiting plate 23. Teeth 26 are fixedly connected to the outer side of the rotating wheel 25. The toothed column 24 and the teeth 26 are meshed. Support blocks 27 are fixedly connected to both ends of the rotating wheel 25. The outer side of the support blocks 27 is in contact with the inside of the limiting plate 23. A handle 28 is fixedly connected to one end of the limiting plate 23.

[0031] The base plate 1 serves as the fundamental support structure for the entire device, providing installation and fixing positions for other components, ensuring the overall stability and rigidity of the device, and ensuring stable support of circuit boards and related components during testing. The second slide groove 5 provides a sliding track for the support plate 21, allowing it to slide smoothly on the base plate 1, thereby changing the relative position between the support plate 21 and the base plate 1 to accommodate the testing requirements of circuit boards of different sizes and specifications. The second slider 6 cooperates with the second slide groove 5 to achieve a sliding connection of the mounting component 4 on the base plate 1, enabling the mounting component 4 to move along the direction of the second slide groove 5, thereby adjusting its position to adapt to the installation requirements of different circuit boards. The support plate 21 connects the second slide groove 5 and the first slider 22, providing stable support and a mounting base for the flipping component 2. Simultaneously, through the cooperation of the first slider 22 and the first slide groove, the flipping component 2 slides and its position is adjusted on the base plate 1. The first slider 22 cooperates with the first slide groove to achieve a sliding connection of the support plate 21 on the base plate 1, allowing the support plate 21 to drive the flipping component 2 on the base plate. The position of the flipping assembly 2 is adjusted by moving the toothed column 24 to meet the needs of different detection positions. The limiting plate 23 is used to fix the toothed column 24 and provide support and positioning for the rotating wheel 25, ensuring the meshing stability and accuracy between the toothed column 24 and the rotating wheel 25, and ensuring the normal operation of the flipping assembly 2. The toothed column 24 meshes with the teeth 26 on the rotating wheel 25. Under the push of the limiting plate 23, the toothed column 24 realizes the rotational movement of the rotating wheel 25, thereby realizing the flipping action of the circuit board, so that the circuit board can be flipped during the detection process. The circuit board can be flipped at different angles to inspect each side. The rotating wheel 25 meshes with the toothed column 24 through the outer teeth 26. When the rotating wheel 25 rotates, it drives the teeth 26 to mesh and rotate on the toothed column 24, thereby flipping the rotating shaft 32. The support block 27 is used to support the rotating wheel 25 to prevent the rotating wheel 25 from shaking or shifting after rotation. The handle 28 makes it convenient for the operator to manually rotate the rotating wheel 25. By rotating the handle 28, the rotating wheel 25 is driven to rotate, thereby realizing the flipping operation of the circuit board, making the operation more convenient and labor-saving.

[0032] like Figure 1 - Figure 4 As shown, the limiting component 3 includes a support frame 31 fixedly connected to both sides of the top of the base plate 1. The support frame 31 is rotatably connected to a rotating shaft 32. A ratchet 33 is fixedly connected to the outside of the rotating shaft 32. A pawl 34 is rotatably connected to the outside of the support frame 31. The ratchet 33 and the pawl 34 are meshed. An extension rod 35 is fixedly connected to both ends of the outside of the rotating shaft 32.

[0033] The support frame 31 is fixed on both sides of the top of the base plate 1, providing support and installation foundation for the entire limiting assembly 3, ensuring the stability and rigidity of the limiting assembly 3. The rotating shaft 32 is installed inside the support frame 31, providing rotational support for the ratchet 33, enabling the ratchet 33 to rotate stably around it, thereby controlling the flip angle of the circuit board. The ratchet 33 is fixed on the outside of the rotating shaft 32 and meshes with the pawl 34. Through the unidirectional transmission characteristics of the ratchet 33 and the pawl 34, the rotation angle of the rotating shaft 32 is limited, thereby controlling the flip angle of the circuit board and preventing the circuit board from flipping excessively. The number of teeth of the ratchet 33 can be designed according to specific flipping requirements. The more teeth, the more accurate the angle rotation. The pawl 34 is rotatably connected to the outside of the support frame 31 and meshes with the ratchet 33. Its unidirectional engagement characteristic makes the rotating shaft 32 rotate only in one direction, thereby achieving precise limiting of the flip angle of the circuit board and ensuring that the circuit board is kept in the appropriate position during the inspection process. The extension rod 35 is fixed at both ends on the outside of the rotating shaft 32 for easy installation of the circuit board.

[0034] like Figure 3 and Figure 5 As shown, the outer side of the limiting component 3 is fixedly connected to the mounting component 4. The mounting component 4 includes a mounting block 41 fixedly connected to the extension rod 35. The mounting block 41 is internally threaded with a threaded post 42, and the bottom end of the threaded post 42 is fixedly connected to a locking block 43.

[0035] Mounting block 41 is fixedly connected to extension rod 35, providing a mounting base for mounting assembly 4 and facilitating subsequent installation of circuit boards. Threaded post 42 is threadedly connected to the inside of mounting block 41. By rotating threaded post 42, its position within mounting block 41 can be adjusted, thereby fixing and positioning the circuit board. Clamping block 43 is fixedly connected to the bottom end of threaded post 42, used to directly contact the circuit board, fixing and limiting the circuit board, ensuring the circuit board remains stable during testing.

[0036] like Figure 1 - Figure 5 As shown:

[0037] In use: First, hold the handle 28 and push it to rotate, causing the slider 22 to slide on the support plate 21. Then, the limiting plate 23 moves linearly, causing the toothed post 24 on the limiting plate 23 to mesh with the toothed tooth 26, thereby causing the rotating wheel 25 on the toothed tooth 26 to rotate. The rotating shaft 32 inside the rotating wheel 25 will transmit the rotational force to the extension rod 35, which will then cause the mounting assembly 4 to flip. After the circuit board mounted on the mounting assembly 4 has finished flipping, the support block 27 will fit against the protruding part on the bottom side of the inner wall of the limiting plate 23. At the same time, the pawl 34 on the support frame 31 will engage with the ratchet 33 to achieve positioning. When flipping is required, the pawl 34 can be pulled up to achieve engagement and flipping. When installing the circuit board, by rotating the threaded post 42, the threaded post 42 will drive the locking block 43 to move up and down, so that the circuit board is installed between the mounting block 41 and the locking block 43 for positioning.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
