[0002] In the fields of electronics manufacturing and related industries, circuit boards, as important electronic components, have a critical impact on product quality and performance due to their dimensional accuracy and hole position accuracy.

[0003] With the rapid development of the electronics industry, while some existing automated testing equipment has improved testing efficiency to a certain extent, it suffers from problems such as complex structure, high cost, and insufficient flexibility. For example, some equipment struggles to quickly adapt to the testing needs of different specifications of circuit boards, and the operation of changing testing components is cumbersome, consuming a lot of time and labor costs, thus failing to meet the needs of diversified production. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a rapid detection device for board size and hole position, which aims to solve the problem that existing detection devices are difficult to quickly adapt to the detection needs of boards of different specifications.

[0005] The present invention adopts the following technical solution:

[0006] The rapid detection device for plate size and hole position includes a measuring base plate and a column plate installed on the measuring base plate.

[0019] To make the purpose, technical solution, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0021] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0022] Combination Figure 1-4 As shown, the rapid detection device for plate size and hole position includes a measuring base plate 1 and a column plate 2 installed on the measuring base plate. The measuring base plate 1 has multiple slots 3. The bottom surface of the column plate 2 is provided with a locking block 4 corresponding to each slot 3. The locking block 4 is inserted into the corresponding slot 3. The measuring base plate 1 is provided with electric calipers 5 at both the horizontal and vertical positions opposite to the column plate. The top surface of the column plate 2 is provided with multiple positioning columns 6.

[0023] In the electronics manufacturing and related fields, circuit boards, as crucial electronic components, have a critical impact on product quality and performance due to their dimensional accuracy and hole placement precision. In practical applications, this device can be used to quickly inspect whether the dimensions and hole positions of circuit boards meet production requirements.

[0024] This testing device includes a measuring base plate and a column plate mounted on the measuring base plate. The base plate is made of 6061 aluminum alloy frame with an anodized surface treatment.

[0025] When using this device to inspect the size and hole position of the standard plate, first select the corresponding model of the column plate and install it on the measuring base plate as required. Then, install the standard plate that meets the requirements on the column plate as required. Next, move the two electric calipers toward the horizontal and vertical positions of the standard plate to measure the length and width of the standard plate.

[0026] The electric calipers transmit measurement data to an external control system and store the reference dimension, which is the preset standard value. After acquiring the reference dimension, the electric calipers first return to their initial position, then remove the standard plate, and subsequently place the plate to be measured. If the plate is installed correctly, the holes will be aligned accurately. The two electric calipers then move towards the horizontal and vertical positions of the plate to be measured, respectively, to measure its width and length. The electric calipers transmit the measurement data to the control system for comparison with the preset standard value.

[0027] like Figure 1-2 The measuring base plate 4 is also equipped with a display screen 7. If a red warning light appears on the display screen, the measurement data of the board under test does not meet the requirements. If a green warning light appears on the display screen, the measurement data of the board under test meets the requirements. At the same time, the electric calipers reset, ready to measure the next board under test.

[0028] As a preferred structure, such as Figure 1 , Figure 3-4 The positioning column 6 includes an anti-pressure support column 61, and the anti-pressure support column 61 has a guide column 62 at its axis. The diameter of the guide column is smaller than the diameter of the anti-pressure support column.

[0029] In this embodiment, the diameter of the positioning column is matched with the design hole tolerance. During the process described above, when using the positioning column to check for deviations in the hole positions of the board under test, the mounting holes on the board under test are first aligned with the positioning column. The board under test is then placed on the positioning column through the mounting holes. If the board under test can be installed correctly, meaning there are no errors in the hole positions, the guide column is inserted into the mounting hole of the board to prevent damage to the bottom surface of the board from pressure.

[0030] During the above testing process, when installing the column plate onto the measuring base plate, simply align the clips on the bottom of the column plate with the slots on the measuring base plate. Once the clips and slots are aligned vertically, the column plate is installed into the slots on the measuring base plate using the clips. The entire installation process is relatively simple and also facilitates the disassembly and replacement of different models of column plates.

[0031] In this device, the electric caliper 5 adopts an L-shaped structure. During the measurement process, the electric caliper contacts the edge of the measuring plate, improving the accuracy of the measurement data. A notch 9 is provided on the measuring base plate 1 directly opposite the electric caliper 5. The notch 9 on the measuring base plate matches the contour of the L-shaped measuring head of the electric caliper 5, not only avoiding interference from the base plate on the caliper's movement but also ensuring that the end face of the measuring head completely fits against the edge of the plate, eliminating measurement blind spots caused by obstruction from the base plate surface and improving measurement accuracy.

[0032] In the diagram, the side wall of the base plate is equipped with a control button group 8 for controlling the forward and backward movement of each electric caliper. The control button group consists of two buttons: one controls the electric caliper to move forward, and the other controls it to move backward. Since electric calipers are existing technology, they will not be described in detail here.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
