Description

Technical Field

[0001] This utility model relates to the field of circuit board testing, and in particular to a circuit board testing device that can adapt to the testing of various circuit boards. Background Technology

[0002] With the rapid development of electronic information technology, circuit boards, as a core component of electronic products, are seeing their application scope expand and product types become increasingly diverse. Circuit boards with different functions and sizes are widely used in numerous fields such as electronic manufacturing, communication equipment, and aerospace. To ensure the quality and performance of circuit boards, precise testing has become an indispensable and crucial step in the production process.

[0003] However, existing circuit board testing devices have many problems. When monitoring circuit boards, it is necessary to install the corresponding specification testing board on the testing table in advance, and then use the probes on the testing board to dock with the circuit board to complete the real-time monitoring of the circuit board. However, most testing devices have a relatively fixed structural design and can only be used for the installation and fixing of testing boards of specific specifications. When facing circuit boards of different specifications, enterprises often need to equip themselves with a variety of different testing devices to install the testing boards. This not only greatly increases the equipment procurement cost, but also brings great inconvenience to equipment management and maintenance.

[0004] Furthermore, when installing the test board, traditional testing devices typically use complex clamps or bolts for fixing, which is cumbersome and requires a lot of time to position and tighten the test board. This results in low efficiency in the preparation work before testing. When faced with circuit boards of different specifications, this fixing method makes it difficult to quickly replace the corresponding test board and cannot achieve rapid adaptation and testing of circuit boards of different specifications, which seriously affects production efficiency.

[0005] Therefore, it is necessary to provide a new circuit board testing device that can adapt to the testing of various circuit boards to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a circuit board testing device that can adapt to the testing of various circuit boards.

[0007] This utility model provides a circuit board testing device adaptable to various circuit board testing methods, comprising: a base, on which a support frame is fixedly connected, and two side frames symmetrically arranged on the base, with a pressure plate positioned above the two side frames; and a matching installation mechanism, comprising two sealing plates, each of which is fixedly connected to one end of a side frame, each of the two side frames having a sliding groove, each of the two sliding grooves having a through opening on its inner wall, each of the two through openings having an adjusting component, each of the two adjusting components having a locking assembly inside, and each of the two adjusting components having an adjusting assembly between it and the two side frames.

[0008] Preferably, the locking assembly includes a built-in plate, which is slidably connected to the inner wall of one end of the adjusting member. A slide rod is fixedly connected in the built-in plate, and a locking head is fixedly connected to one end of the slide rod. An internal spring is sleeved on the slide rod.

[0009] Preferably, a lever is fixedly connected to the other end of the slide rod, and the locking head is a wedge-shaped head.

[0010] Preferably, the adjustment component includes a longitudinal adjustment shaft, and both ends of the sidewalls of the side frame are provided with protruding plates. The two ends of the longitudinal adjustment shaft are respectively rotatably connected to the two protruding plates. A bottom block is fixedly connected to the adjustment component. The longitudinal adjustment shaft is a threaded rod. The bottom block is threadedly connected to the longitudinal adjustment shaft. A main throttle is installed and connected to one end of the longitudinal adjustment shaft.

[0011] Preferably, a crossbar is fixedly connected to the base, the lower ends of the two side frames are slidably connected to the two ends of the crossbar, a transverse adjustment shaft is rotatably connected to the base, the two ends of the transverse adjustment shaft are provided with threads in opposite directions, the lower ends of the two side frames are threaded to the two ends of the transverse adjustment shaft, and a secondary throttle is fixedly connected to one end of the transverse adjustment shaft.

[0012] Preferably, a pull rod is slidably connected at the middle position of the upright frame, a horizontal handle is fixedly connected to the upper end of the pull rod, the lower end of the pull rod is fixedly connected to the pressure plate, a secondary rod is fixedly connected between the horizontal handle and the pressure plate, the secondary rod is slidably connected to the upright frame, and a return spring is sleeved on the secondary rod.

[0013] Compared with related technologies, the circuit board testing device provided by this utility model, which can adapt to the testing of various circuit boards, has the following beneficial effects:

[0014] This invention allows for flexible adjustment of the positions of the side frames and adjusting components via a horizontal and vertical adjustment shaft. Rotating the secondary handle allows the two side frames to move laterally along the crossbar, precisely adapting to circuit boards of different widths. Rotating the main handle enables the adjusting components to move longitudinally within the side frame grooves, accommodating circuit boards of different lengths. This multi-dimensional adjustment function gives the device high versatility, meeting the testing requirements of circuit boards of various specifications. It eliminates the need for multiple testing devices for different specifications of circuit boards, significantly reducing equipment procurement costs and storage space requirements for enterprises.

[0015] 2. This utility model allows the detection plate to be directly slidably inserted between two side frames. The detection plate abuts against the inclined surface of the clamp head, causing the slide rod to slide and compress the built-in spring. After insertion, the built-in spring pushes the slide rod to reset, and the wedge-shaped clamp head locks the edge of the detection plate, achieving quick and firm fixation of the detection plate. This effectively saves preparation time before testing and improves testing efficiency. The detection plate with the corresponding pin can be selected in real time according to the different specifications of the circuit board being tested, and quick installation can be performed, further enhancing the practicality and flexibility of the device.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1 to 4A circuit board testing device adaptable to various circuit board testing includes: a base 1, a support frame 11 fixedly connected to the base 1, two side frames 2 symmetrically arranged on the base 1, and a pressure plate 3 located above the two side frames 2; a matching installation mechanism, which includes two sealing plates 4, each of which is fixedly connected to one end of the two side frames 2, each of the two side frames 2 having a sliding groove, each of the two sliding grooves having a through opening on its inner wall, each of the two through openings having an adjusting component 41, each of the two adjusting components 41 having a locking component inside, and each of the two adjusting components 41 having an adjusting component between it and the two side frames 2.

[0023] In the specific implementation process, such as Figure 3 and Figure 4 As shown, the locking assembly includes a built-in plate 42, which is slidably connected to the inner wall of one end of the adjusting member 41. A slide rod 43 is fixedly connected in the built-in plate 42, and a clip 44 is fixedly connected to one end of the slide rod 43. A built-in spring 45 is sleeved on the slide rod 43.

[0024] It should be noted that: the built-in spring 45 is sleeved on the slide rod 43, with one end abutting against the inner wall of the adjusting component 41 and the other end fixedly connected to the built-in plate 42, providing elastic force for the slide rod 43 to reset. When the circuit board is inserted, the clamp 44 is squeezed by the circuit board, and the slide rod 43 slides relative to it against the elastic force of the built-in spring 45. When the circuit board is inserted into place, the built-in spring 45 releases its elastic potential energy, pushing the slide rod 43 to reset, so that the clamp 44 locks the edge of the circuit board, thereby locking and fixing the circuit board. It can realize automatic locking and releasing of the circuit board, and select the corresponding pin detection board in real time according to the different specifications of the circuit board being tested, and perform quick installation.

[0025] refer to Figure 4 As shown, the other end of the slide bar 43 is fixedly connected to the paddle 5, and the locking head 44 is a wedge-shaped head.

[0026] It should be noted that when the circuit board needs to be disassembled, the operator only needs to move the lever 5 to drive the slide bar 43 to overcome the elastic force of the built-in spring 45 and move it away from the circuit board, so that the clip 44 can be disengaged from the edge of the circuit board and the circuit board can be easily disassembled.

[0027] The wedge-shaped head 44 guides the circuit board to insert smoothly when it comes into contact with the circuit board. At the same time, when locking, the right-angled surface fits tightly with the edge of the circuit board, effectively preventing the circuit board from loosening or falling off during the testing process.

[0028] refer to Figure 2 and Figure 3As shown, the adjustment assembly includes a longitudinal adjustment shaft 6, and protruding plates are provided on both ends of the side wall of the side frame 2. The two ends of the longitudinal adjustment shaft 6 are rotatably connected to the two protruding plates respectively. A bottom block 411 is fixedly connected to the adjustment component 41. The longitudinal adjustment shaft 6 is a threaded rod, and the bottom block 411 is threadedly connected to the longitudinal adjustment shaft 6. A main throttle 61 is installed and connected to one end of the longitudinal adjustment shaft 6.

[0029] It should be noted that when the main throttle 61 is turned, the longitudinal adjustment shaft 6 rotates, and the bottom block 411 moves along the axial direction of the longitudinal adjustment shaft 6 due to the threaded drive, thereby driving the adjusting component 41 to move longitudinally within the slide groove of the side frame 2. This threaded drive method has the characteristics of accurate transmission ratio and good self-locking, which can accurately adjust the relative position between the adjusting component 41 and the corresponding sealing plate 4 to accommodate circuit boards of different lengths. After adjustment, the adjusting component 41 can be stably maintained in the current position and will not easily move due to external forces.

[0030] refer to Figure 1 and Figure 2 As shown, a crossbar 7 is fixedly connected in the base 1, and the lower ends of the two side frames 2 are slidably connected to the two ends of the crossbar 7 respectively. A transverse adjustment shaft 71 is rotatably connected in the base 1. The two ends of the transverse adjustment shaft 71 are provided with threads in opposite directions. The lower ends of the two side frames 2 are threadedly connected to the two ends of the transverse adjustment shaft 71 respectively. A secondary throttle 72 is fixedly connected to one end of the transverse adjustment shaft 71.

[0031] It should be noted that: the crossbar 7 provides guidance and support for the lateral movement of the side frame 2, ensuring that the side frame 2 remains stable during movement and does not shift or sway.

[0032] The auxiliary throttle 72 is used to drive the lateral adjustment shaft 71 to rotate. The threaded design with opposite directions at both ends of the lateral adjustment shaft 71 allows the two side frames 2 to move synchronously towards or away from each other on the crossbar 7. When the auxiliary throttle 72 is rotated, the two side frames 2 will move closer or further away simultaneously according to the threaded transmission principle, thereby precisely adjusting the lateral distance between the two side frames 2 to adapt to circuit boards of different widths.

[0033] refer to Figure 1 and Figure 2 As shown, a pull rod 8 is slidably connected at the middle position of the upright frame 11. A horizontal handle 81 is fixedly connected to the upper end of the pull rod 8. The lower end of the pull rod 8 is fixedly connected to the pressure plate 3. A secondary rod 82 is fixedly connected between the horizontal handle 81 and the pressure plate 3. The secondary rod 82 is slidably connected to the upright frame 11. A return spring 83 is sleeved on the secondary rod 82.

[0034] It should be noted that when the horizontal handle 81 is pulled upward, the pull rod 8 moves the pressure plate 3, and the return spring 83 undergoes elastic deformation, which makes it easy to align the circuit board on the test board, so that each probe is connected to the corresponding connector. After releasing the horizontal handle 81, the return spring 83 returns to its elastic deformation, so that the pressure plate 3 presses the circuit board, which facilitates the installation and testing of the circuit board.

[0035] The working principle of the circuit board testing device that can adapt to the testing of various circuit boards provided by this utility model is as follows: Rotating the secondary rotary handle 72 drives the lateral adjustment shaft 71 to rotate in the base 1, so that the two side frames 2 move laterally towards or away from each other along the crossbar 7. It can accurately adjust the lateral distance between the two side frames 2 according to the lateral size of the circuit board to adapt to circuit boards of different widths. Then, rotating the two main rotary handles 61 in sequence causes the longitudinal adjustment shaft 6 to rotate between the protrusions on the side walls at both ends of the side frame 2, which drives the adjustment component 41 to move longitudinally in the slide groove of the side frame 2. It can accurately adjust the relative position between the adjustment component 41 and the corresponding sealing plate 4 according to the longitudinal size of the circuit board, thereby further adapting to circuit boards of different lengths.

[0036] The corresponding specification test board is slidably inserted between the two side frames 2. The side walls at both ends of the test board abut against the inclined surfaces of the two clips 44, so that the two clips 44 drive the two slide rods 43 to slide relative to each other. The built-in springs 45 undergo elastic deformation until the test board is fully inserted. Then, the two built-in springs 45 push the slide rods 43 to reset and move, so that the wedge-shaped clips 44 lock the edge of the circuit board, thus quickly and firmly fixing the circuit board in the base 1. This ensures that the circuit board will not shift during the test. Furthermore, the test board with the corresponding pins can be selected in real time and quickly installed according to the different specifications of the circuit board being tested, which is very convenient.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
