Description

Technical Field

[0001] This application relates to the field of printed circuit board technology, and more specifically, to a measuring device for printed circuit boards. Background Technology

[0002] Circuit boards are one of the most fundamental components of electronic products. To ensure the performance and quality of circuit boards, various measurements are required. These measurements are fundamental in determining whether a circuit board meets specifications and requirements, and are therefore of paramount importance.

[0003] A search revealed that patent CN220689972U discloses a measuring device for printed circuit boards, including a base with symmetrically distributed notches. A round rod is fixedly connected to each notch, and the round rod is slidably connected to a sliding hole in a push plate. A fixing block is fixedly connected to the base, and the fixing block has a second scale. The base has a first scale. The thickness of the circuit board is measured on the base via a mating component. In this invention, a spring pushes the push plate closer to the fixing block, and the fixing block and push plate clamp and fix the circuit board. Under the action of the first and second scales, the length and width of the circuit board can be directly obtained, which is convenient. Furthermore, under the action of the second spring, the pressure plate moves downward, pressing the circuit board downward and fixing it. At this time, the thickness of the circuit board on the base can be obtained through the third scale, thus allowing the length, width, and height of the circuit board to be determined in one go, which is simpler and faster.

[0004] Although the aforementioned patent can determine the length, width, and height of the circuit board in one measurement, it uses springs to clamp and fix the circuit board during the measurement process. The springs exert some pressure on the circuit board, and it is difficult to ensure that the spring pressure is evenly distributed. This can easily cause excessive local stress on the circuit board, resulting in deformation, which can damage its flatness, interfere with the normal transmission of signals within the board, and shorten the service life of the circuit board.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Reference Figures 1-5A measuring device for printed circuit boards includes a support base 1, at least one measuring platform 2 is provided on the top of the support base 1, and a measuring component is provided on one side of each measuring platform 2.

[0029] Each measuring unit includes a length and width measuring unit, a height measuring unit, and a limiting unit. Each length and width measuring unit includes a lateral alignment rod 3 and a longitudinal alignment rod 4. Each height measuring unit includes a moving rod 18. Each lateral alignment rod 3, longitudinal alignment rod 4, and moving rod 18 is used to measure the length, width, and height of the circuit board. Each limiting unit includes a limiting plate 7. The number of limiting plates 7 is set to two. The two limiting plates 7 are used to limit the circuit board during measurement.

[0030] Reference Figures 1-5 Each horizontal alignment rod 3 and vertical alignment rod 4 is respectively set on the top of the corresponding measuring platform 2. Each horizontal alignment rod 3 and vertical alignment rod 4 is vertically arranged. Each horizontal alignment rod 3 and vertical alignment rod 4 has a first scale 5 at its top. Each measuring platform 2 has a support rod 15 on one side of its top. Each support rod 15 has a sliding hole 17 on one side. Each sliding hole 17 is slidably connected to a corresponding moving rod 18. Each moving rod 18 has a stop plate 19 at its bottom end. Each moving rod 18 has a lever 23 at its end away from the stop plate 19. Each of the moving rods 18 has a second pointer 22 on one side of its top end. Each of the support rods 15 has a fixing plate 20 on one side. Each fixing plate 20 is arranged parallel to the corresponding moving rod 18. Each fixing plate 20 has a second scale 21 on one side. Each of the horizontal alignment rods 3 and the vertical alignment rods 4 has a first sliding groove 6 on one side. Each of the limiting plates 7 has a slider 8 fixedly connected to one side. Each slider 8 is slidably connected to the corresponding first sliding groove 6. Each first sliding groove 6 has a friction block on its inner wall. Each limiting plate 7 has a first pointer 9 at its bottom end.

[0031] The measuring component enables rapid measurement of the circuit board. Specifically, the measurement process involves first sliding the limiting plates 7 on the horizontal alignment rod 3 and the vertical alignment rod 4 according to the approximate dimensions of the circuit board. Using the first pointer 9 and the first scale 5, the limiting plates 7 are adjusted to a suitable position, thus determining the placement boundary of the circuit board on the measuring platform 2 and providing initial positioning. Next, the circuit board is placed on the measuring platform 2, with one corner positioned diagonally opposite the horizontal alignment rod 3 and the vertical alignment rod 4, aligning one edge with the vertical alignment rod 4 and one end edge with the horizontal alignment rod 3. At this point, the measurement can be performed using the horizontal alignment rod 3. The length and width dimensions of the circuit board are directly read from the first scale 5 at the top of the longitudinal alignment rod 4. Then, the lever 23 is operated to make the moving rod 18 slide downward in the sliding hole 17, which drives the abutment plate 19 close to the circuit board until the abutment plate 19 is in close contact with the upper surface of the circuit board. At this time, the scale indicated by the second pointer 22 on one side of the top of the moving rod 18 on the second scale 21 on the side of the fixed plate 20 is the height dimension of the circuit board. Thus, the measurement process of the length, width and height of the circuit board is completed quickly and relatively accurately. The entire measuring device has a reasonable structural design and is easy to operate, which can effectively improve the measurement efficiency and accuracy of printed circuit boards.

[0032] The measuring components ensure that the circuit board is relatively fixed on the measuring platform 2, preventing displacement during the measurement process and improving the accuracy of length and width measurements. Furthermore, by sliding the limit plate 7 according to the approximate size of the circuit board, and through the cooperation of the first pointer 9 and the first scale 5, the placement boundary can be easily determined. This operation is simple and easy to understand, requiring no complex tools or professional knowledge, greatly improving the efficiency of measurement preparation. It can also adapt to circuit boards of different sizes, increasing the versatility of the device. This measurement method can save a significant amount of time, allowing the production or testing process of the circuit board to proceed more smoothly and effectively improving overall work efficiency.

[0033] Reference Figure 3 Each limiting plate 7 has an operating lever 10 on its top, and each operating lever 10 has a protective pad 11 on one side. Each protective pad 11 has a protrusion on its outer wall.

[0034] The operation lever 10 provides a convenient point of leverage for the operator to adjust the position of the limit plate 7, making the operation more flexible and efficient, thereby improving operational efficiency.

[0035] Reference Figure 5 The support base 1 has a vertical plate 12 on one side of the top. The top of the vertical plate 12 has a second sliding groove 13. Multiple sliding rods 14 are slidably connected inside the second sliding groove 13. The top of each sliding rod 14 is fixedly connected to a rotating shaft 16. Each support rod 15 is rotatably connected to the outer wall of the corresponding rotating shaft 16.

[0036] By sliding the slide bar 14 within the second slide groove 13 of the upright plate 12, the position of the height measuring unit can be flexibly adjusted according to actual measurement needs, and the abutment plate 19 can be better attached to the upper surface of the circuit board in the most suitable position, thereby expanding the measurement range of the device.

[0037] Working principle: First, based on the approximate size of the circuit board, slide the limiting plates 7 on the horizontal alignment rod 3 and the vertical alignment rod 4. Using the first pointer 9 in conjunction with the first scale 5, adjust the limiting plates 7 to a suitable position, thereby determining the placement boundary of the circuit board on the measuring platform 2 and playing a preliminary limiting role. Next, place the circuit board on the measuring platform 2, placing one corner of the circuit board at the diagonal of the horizontal alignment rod 3 and the vertical alignment rod 4, aligning one edge with the vertical alignment rod 4 and one end edge with the horizontal alignment rod 3. At this time, the limit plates 7 can be adjusted by sliding the first pointer 9 and the first scale 5 on the top of the horizontal alignment rod 3 and the vertical alignment rod 4. The length and width dimensions of the circuit board are directly read by a scale 5. Then, the lever 23 is operated to make the moving rod 18 slide downward in the sliding hole 17, which drives the abutment plate 19 close to the circuit board until the abutment plate 19 is in close contact with the upper surface of the circuit board. At this time, the scale indicated by the second pointer 22 on the top side of the moving rod 18 on the second scale 21 on the side of the fixed plate 20 is the height dimension of the circuit board. Thus, the measurement process of the length, width and height of the circuit board is completed quickly and relatively accurately. The entire measuring device has a reasonable structural design and is easy to operate, which can effectively improve the measurement efficiency and accuracy of printed circuit boards.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
