[0002] In the printed circuit board production industry, in order to facilitate users to more easily separate the spliced circuit boards after electrical installation, a V-cut process, that is, a V-shaped separation groove, is usually added to the circuit board. The depth of the V-shaped separation groove affects the separation difficulty and splicing quality of the printed circuit board. If the V-shaped separation groove is too deep, the connection of the spliced printed circuit board may fail, affecting welding; if the V-shaped separation groove is too shallow, it is difficult to separate the printed circuit board after welding.
[0003] Currently, in the prior art, the inspection of the V-shaped separation groove is usually to place the circuit board on the measuring support plate, then insert the blade into the gap of the V-shaped separation groove, and read the scale on the blade to determine whether the depth of the V-shaped separation groove is qualified. However, the sizes of the entire circuit boards vary, and the size of the measuring support plate is not adjustable. Therefore, when detecting a large-sized entire circuit board, the entire circuit board may be unbalanced, thereby affecting the measurement accuracy. Summary of the Utility Model

Of course, these are only embodiments or examples and are not intended to be restrictive. Additionally, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present utility model and do not represent a specific relationship between the different embodiments and / or structures being discussed.
[0021] As Figures 1 - 5 shown, a circuit board V-groove detector includes a base 1, an L-shaped upper seat 2 is arranged on the base 1, a longitudinal slide rail 3, a tool holder 4, a blade 5, a digital display micrometer 6, a gauge block 7 and a limit component 8 are arranged on the front side of the L-shaped upper seat 2. The tool holder 4 slides up and down on the longitudinal slide rail 3, the blade 5 is installed at the lower end of the tool holder 4, the digital display micrometer 6 is installed directly above the tool holder 4 through the gauge block 7, and the measuring probe of the digital display micrometer 6 abuts against the upper end face of the tool holder 4. The limit component 8 is used to limit the downward sliding of the tool holder 4. A measuring support plate 9 is arranged on the front side of the base 1 and directly below the blade 5. Auxiliary support plates 11 are hinged to both the left and right sides of the measuring support plate 9 through hinges 10. The auxiliary support plates 11 can swing and fit together on both sides of the measuring support plate 9, or swing and fit against both sides of the base 1.
[0022] In the present utility model, by hinging auxiliary support plates 11 to both the left and right sides of the measuring support plate 9, the auxiliary support plates 11 can swing and fit together on both sides of the measuring support plate 9, or swing and fit against both sides of the base 1. Thus, according to the size of the entire circuit board, the auxiliary support plates 11 can be selectively turned out or folded up, increasing the support area for the circuit board, ensuring the stability during the depth detection of the V-shaped separation groove of the circuit board, and improving the measurement accuracy.
[0023] Of course, when the auxiliary support plates 11 swing and fit together on both sides of the measuring support plate 9, the end faces of the auxiliary support plates 11 are flush with those of the measuring support plate 9.
[0024] See Figure 2 shown, rotating shafts 21 are symmetrically installed at the lower left and right ends of the measuring support plate 9. An auxiliary swing rod 22 is arranged at the lower end of the rotating shaft 21. The auxiliary swing rod 22 can swing and fit flush against the front side of the measuring support plate 9, or extend forward in front of the measuring support plate 9. Thus, when it is necessary to detect a larger entire circuit board, the auxiliary swing rod 22 can be swung forward to further increase the support area for the circuit board, improving the stability and accuracy of the detection.
[0025] See Figure 4 、 Figure 5As shown, the gauge base 7 includes a horizontally arranged plate 31 and a vertically arranged plate 32 which are integrally formed. The horizontally arranged plate 31 is installed at the upper end of the L-shaped upper seat 2. A vertical through groove 33 is provided on the vertically arranged plate 32. A connecting plate 34 is arranged at the rear side of the digital display micrometer 6. A bolt 35 and a nut 36 are further included. The bolt 35 sequentially passes through the connecting plate 34 and the vertical through groove 33 and is threadedly connected to the nut 36.
[0026] When installing the gauge base 7, the horizontally arranged plate 31 is fixed to the upper end of the L-shaped upper seat 2 by screws. Then, when fixing the digital display micrometer 6, the bolt 35 passes through the connecting plate 34 and the vertical through groove 33 and is threadedly connected to the nut 36, thereby fixing the digital display micrometer 6 on the gauge base 7. It is worth mentioning that through the arrangement of the vertical through groove 33, the up-and-down height of the digital display micrometer 6 can be adjusted to adapt to the detection of circuit boards with different thicknesses.
[0027] See Figure 4 As shown, the limiting component 8 includes a fixed seat 41, a cam 42, a roller 43, a rotating member 44 and a stop block 46. The fixed seat 41 is arranged on the front side of the L-shaped upper seat 2. The cam 42 is arranged on the rotating member 44. The rotating member 44 is rotatably installed on the fixed seat 41. The roller 43 is arranged on the cam 42. The stop block 46 is arranged on one side of the tool holder 4 and directly above the roller 43.
[0028] When detecting the depth of the V-shaped separation groove of the circuit board, first, the roller 43 on the cam 42 jacks up the stop block 46. Then, the circuit board to be measured is placed on the measuring support plate 9. Then, the rotating member 44 drives the cam 42 to rotate. Due to its own gravity, the tool holder 4 descends, so that the blade 5 at the lower end of the tool holder 4 is inserted into the V-shaped separation groove of the circuit board. The digital display micrometer 6 displays the value, and then it is determined whether the depth of the V-shaped separation groove is qualified.
[0029] In order to facilitate the rotation of the rotating member 44, a handle 51 is arranged at one end of the rotating member 44.
[0030] In the present utility model, a first magnet 61 capable of magnetically attracting the measuring support plate 9 and a second magnet capable of magnetically attracting the base 1 are respectively arranged on the auxiliary support plate 11; thereby, the auxiliary support plate 11 can be stably swung and joined on both sides of the measuring support plate 9, or stably swung and attached to both sides of the base 1.
[0031] In order to facilitate the picking and placing of the circuit board V-groove detector, a handle 71 is arranged at the upper end of the L-shaped upper seat 2.
[0032] In the present utility model, a protective cover 81 is arranged on the front side of the L-shaped upper seat 2. The longitudinal slide rail 3, the tool holder 4 and the limiting component 8 are arranged inside the protective cover 81.
