Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board production, and particularly relates to a detection tool for a circuit board. Background Art

[0002] Before the circuit board enters the market for use after being processed, it also needs to go through a power-on detection process to ensure that the circuit board can be used normally. The traditional detection process usually involves manually holding the circuit board to be tested and checking it one by one.

[0003] For example, Chinese Utility Model CN220473653U discloses a protective circuit board detection tool. The circuit board is placed between a clamping frame and a pressing frame. Pressing the insulating plate drives the pressing frame to move downward, driving the circuit board to contact the contact posts, and then the circuit board can be detected. During the detection process, the tester does not contact the circuit board, thus avoiding the occurrence of electric shock and injury due to damage to the surface coating of the circuit board.

[0004] However, in the above-mentioned prior art, before detection, the circuit board needs to be manually placed between the clamping frame and the pressing frame. Due to the obstruction of the insulating plate, it is inconvenient to place and remove the circuit board, and the placement position cannot be accurately positioned, resulting in poor overall usability and stability. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a detection tool for a circuit board, which limits the horizontal position and vertical position of the circuit board through two stop bars and two limiting bars on the support plate, and solves the problem of poor existing usability and stability.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a detection tool for a circuit board, including a base and a detection board located on the upper surface of the base. The base is fixedly connected with a plurality of guide rods, and a support plate is movably inserted through the plurality of guide rods. The guide rods are sleeved with compression springs for supporting the support plate through the compression springs. The support plate is provided with a detection opening corresponding to the position of the detection board. Two stop bars are fixedly connected to the upper surface of the support plate. The two stop bars are symmetrically arranged relative to the detection opening, and limiting bars are fixedly connected to the opposite sides of the two stop bars. A gap is left between the limiting bars and the upper surface of the support plate. One end of the two stop bars is inserted into the circuit board to limit the horizontal position of the circuit board through the two stop bars, and the vertical position of the circuit board is limited through the two limiting bars. By pressing down the support plate, the circuit board contacts the detection board through the detection opening to achieve detection.

[0008] As a preferred technical solution of the utility model, the length of the limiting bar is less than the length of the stop bar, which is convenient for placing the circuit board between the two stop bars.

[0009] As a preferred technical solution of the present utility model, avoidance notches are provided at both ends of the support plate to facilitate the picking and placing of the circuit board.

[0010] As a preferred technical solution of the present utility model, two rotating shafts are rotatably connected to the support plate, and the two rotating shafts are respectively located outside one ends of the two retaining bars; torsion springs are sleeved on the rotating shafts, and strip-shaped blocks are fixedly connected thereto, and one end of the strip-shaped block extends between the two retaining bars for positioning the detection position of the circuit board through the strip-shaped block, and the strip-shaped block is rotated by squeezing the circuit board, so that the circuit board can be taken out between the two retaining bars.

[0011] As a preferred technical solution of the present utility model, the end face of the strip-shaped block is in close contact with the retaining bar, so that the length direction of the strip-shaped block is perpendicular to the length direction of the retaining bar.

[0012] As a preferred technical solution of the present utility model, a plurality of guide posts are movably inserted through the support plate, and a lower pressing plate is fixedly connected through the plurality of guide posts, and springs are sleeved on the guide posts; the lower pressing plate is located above the support plate, and a plurality of pressing rods are fixedly connected to the lower surface of the lower pressing plate for pressing the circuit board by pressing the lower pressing plate and using the pressing rods.

[0013] As a preferred technical solution of the present utility model, an insulating rubber block is fixedly connected to the lower end of the pressing rod.

[0014] The present utility model has the following beneficial effects:

[0015] The present utility model defines the horizontal position and the up-and-down position of the circuit board respectively through the two retaining bars and the two limiting bars on the support plate, so that the accuracy of the placement position of the circuit board is effectively improved, and the stability of the detection use is ensured.

[0016] And the movement of the circuit board is guided by using the two retaining bars, which is convenient for the circuit board to be placed or taken out, thereby effectively improving the convenience of the overall use.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0031] In the description of the present utility model, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationships are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0032] Embodiment 1

[0033] Please refer to Figure 1 and 2 As shown, the present utility model is a detection tooling for a circuit board, including a base 1 and a detection board 101 located on the upper surface of the base 1. The base 1 and the detection board 101 can adopt the technical solutions of the prior art in the background art.

[0034] The base 1 is fixedly connected with four guide rods 102, and a support plate 2 is movably inserted through the four guide rods 102. The guide rods 102 are sleeved with compression springs 103 for supporting the support plate 2 through the compression springs 103, and by pressing the support plate 2, the support plate 2 can move downward.

[0035] As Figure 4 and 5 shown, the support plate 2 is provided with a detection opening 201 corresponding to the position of the detection board 101. Two retaining strips 202 are fixedly connected to the upper surface of the support plate 2. The two retaining strips 202 are symmetrically arranged relative to the detection opening 201, and limiting strips 203 are fixedly connected to the opposite sides of the two retaining strips 202. The support plate 2 can be a nylon plate, and the retaining strips 202, the limiting strips 203 and the support plate 2 can be of an integral structure and obtained by machining.

[0036] As Figure 6 and 7 shown, there is a gap between the limiting strip 203 and the upper surface of the support plate 2 for inserting one end of the two retaining strips 202 into the circuit board, limiting the horizontal position of the circuit board through the two retaining strips 202, and limiting the up and down position of the circuit board through the two limiting strips 203.

[0037] Among them, as Figure 5 and 8 shown, the length of the limiting strip 203 is less than the length of the retaining strip 202, so that the circuit board 5 can be directly placed on the support plate 2, facilitating the placement of the circuit board 5 between the two retaining strips 202. At the same time, avoiding grooves 204 are provided at both ends of the support plate 2 to facilitate the picking and placing of the circuit board 5.

[0038] After the circuit board 5 is placed on the support plate 2, it moves to the left and reaches the position of the detection port 201. At this time, by pressing down the support plate 2, since the circuit board 5 is restricted by the limiting strip 203, the circuit board is in contact with the detection board 101 through the detection port 201, thereby realizing detection.

[0039] After the detection is completed, release the support plate 2. Under the action of the compression spring 103, the support plate 2 moves upward to reset. At this time, the circuit board 5 can be directly pulled out from the left, or another untested circuit board 5 can be inserted from the right, and the tested circuit board 5 can be directly squeezed out, thereby effectively improving the overall convenience of use.

[0040] Embodiment Two

[0041] As Figure 3 and 4 shown, on the basis of Embodiment One, two rotating shafts 3 are rotatably connected to the support plate 2, and the two rotating shafts 3 are respectively located outside one end of the two stop strips 202. A torsion spring 301 is sleeved on the rotating shaft 3, and a strip-shaped block 302 is fixedly connected thereto, and one end of the strip-shaped block 302 extends between the two stop strips 202.

[0042] Moreover, as Figure 8 shown, the end face of the strip-shaped block 302 is in close contact with the stop strip 202, so that the length direction of the strip-shaped block 302 is perpendicular to the length direction of the stop strip 202. When the circuit board 5 is inserted from the right, the left side of the circuit board 5 abuts against the two strip-shaped blocks 302, thereby positioning the detection position of the circuit board through the strip-shaped blocks 302 and ensuring the accuracy of the detection position and the stability of the detection of the circuit board 5.

[0043] As Figure 9 shown, when the detection is completed and the circuit board 5 needs to be taken out, directly pull the circuit board 5, or insert another untested circuit board 5 from the right, and directly push the tested circuit board 5 to the left. By the circuit board 5 squeezing and pushing the strip-shaped block 302, the strip-shaped block 302 rotates outward, so that the circuit board 5 can pass through between the two strip-shaped blocks 302, that is, the circuit board 5 can be taken out between the two stop strips 202. Thus, while improving the accuracy of the detection position of the circuit board 5 through the strip-shaped block 302, the convenience of taking and placing the circuit board 5 is also ensured.

[0044] Embodiment Three

[0045] As Figure 1 、 2 and 4 shown, on the basis of Embodiment One or Embodiment Two, four guide posts 401 are movably inserted through the support plate 2, and a lower pressing plate 4 is fixedly connected through the four guide posts 401, and a spring 402 is sleeved on the guide post 401.

[0046] The lower pressing plate 4 is located above the support plate 2. Two to four pressing rods 403 are fixedly connected to the lower surface of the lower pressing plate 4. After the circuit board 5 is placed, by pressing the lower pressing plate 4, the lower pressing plate 4 moves downward, and the circuit board 5 is pressed downward through the pressing rods 403. When pressing further, the support plate 2 is driven to move downward synchronously, so that the circuit board 5 is pressed downward through the pressing rods 403, further improving the fixing effect of the position of the circuit board 5 and ensuring the stability of detection.

[0047] At the same time, an insulating rubber block 404 is fixedly connected to the lower end of the pressing rod 403. The insulating rubber block 404 can not only reduce the risk of damage to the circuit board 5, but also improve the overall insulation effect and ensure the reliability of use.

[0048] In the description of this specification, the description with reference to terms such as "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.
