Technical Field
[0001] This utility model relates to the field of circuit board testing technology, and in particular to a ceramic circuit board testing device. Background Technology
[0002] Circuit boards serve as the support and electrical connection carrier for electronic components. They typically consist of an insulating substrate, conductive copper foil, and solder pads. The circuitry on a circuit board connects various electronic components through conductive layers to perform specific electronic functions. Ceramic circuit boards are a special type of circuit board whose substrate is made of ceramic material, rather than the traditional epoxy resin and glass fiber composite material. Ceramic circuit boards possess excellent high-temperature stability, good thermal conductivity, and electrical insulation properties, and are widely used in high-performance electronic devices.
[0003] During the drilling process of circuit boards, hole position deviations often occur, preventing the subsequent installation of circuit components and affecting product quality and performance. Therefore, accurate detection of the hole positions on circuit boards is necessary. Existing detection tools, such as the circuit board hole position detection fixture disclosed in patent CN210426381U, which uses positioning posts on the fixture base to detect circuit boards, are limited to different circuit board models. The positioning post design is only applicable to a specific model. When a new model of circuit board is used, the positioning post needs to be redesigned, wasting the previous fixture and increasing production costs. In view of this, this utility model proposes a ceramic circuit board detection device to solve the aforementioned technical problems. Utility Model Content

[0008] In one embodiment, a displacement detector for detecting piston plate displacement is installed inside the cavity, and an alarm is installed on the slide.
[0009] In one embodiment, a groove adapted to the mounting plate is provided on the bottom of the sealing cylinder.
[0010] In one embodiment, a limit rod is installed on the top of the slide block by a second countersunk bolt. The limit rod is slidably connected to the sealing cylinder, and scales are marked on the limit rod and the T-shaped slide groove.

Detailed Implementation
[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0022] A ceramic circuit board testing device, such as Figures 1-6As shown, the device includes a base 101 with four T-shaped grooves 1011. One end of each T-shaped groove 1011 is an open end 1012, and the other end is a closed end 1013. An adjusting device 200 is slidably connected within each T-shaped groove 1011. Each adjusting device 200 has at least one probe 104, allowing it to slide into the open end 1012 of the T-shaped groove 1011. A locking block 801 is provided on the open end 1012 of the T-shaped groove 1011, and the locking block 801 is fixedly mounted on the base 101 by a first countersunk bolt 802. This allows for easy addition or removal of the adjusting device 200, i.e., adding or removing the probe 104, to accommodate various sizes. The ceramic circuit board has a specific size and shape. The adjustment device 200 includes a slide block 201 slidably connected within a T-shaped slide groove 1011. A mounting plate 202 is fixedly connected to the center of the top surface of the slide block 201. A bidirectional threaded rod 203 is rotatably connected to the mounting plate 202. A buffer is threadedly connected to the bidirectional threaded rod 203, and a probe 104 is provided on the buffer. When two adjacent slide blocks 201 are located on the same straight line, the two bidirectional threaded rods 203 are in contact but not under force, that is, the two adjacent bidirectional threaded rods 203 will not interfere with each other and can cover the entire detection area of the base 101. The buffer includes a sealing cylinder 301 threadedly connected to the bidirectional threaded rod 203, and an inner cavity 3011 is provided inside the sealing cylinder 301. A mounting base 302 is slidably connected to the upper end of the inner cavity 3011. A probe 104 is mounted on the mounting base 302. A piston plate 303 is slidably connected to the sealing cylinder 301. A buffer zone 3012 is provided between the piston plate 303 and the mounting base 302. The buffer zone 3012 is filled with a buffer material, specifically hydraulic oil. An elastic element 304, specifically a spring, is provided between the piston plate 303 and the sealing cylinder 301. In this way, through the action of hydraulic oil and the elastic element 304, the impact between the probe 104 and the circuit board can be reduced, avoiding damage to the circuit board or wear on the probe 104 itself. A rotating groove 3021 is provided in the mounting base 302, and a rotating groove 3021 is provided on the side wall of the probe 104. There is a protrusion 401 that matches the rotating groove 3021. The upper part of the rotating groove 3021 is a straight groove and the lower part is an annular groove. This makes it easy to install the probe 104. Simply insert it into the rotating groove 3021 and rotate it once to install the probe 104 in the mounting base 302. The installation process is simple and convenient. A displacement detector 501 for detecting the displacement of the piston plate 303 is installed in the inner cavity 3011. An alarm 502 is installed on the slide 201. When the displacement detector 501 detects that the piston plate 303 has moved, the displacement detector 501 will transmit the signal to the external controller. The external controller will then activate the corresponding alarm 502 to sound an alarm and remind the operator.
[0023] The bottom of the sealing cylinder 301 is provided with a groove 3013 that matches the mounting plate 202. When two adjacent sealing cylinders 301 on the same bidirectional threaded rod 203 come into contact, it represents the shortest distance between the detection holes. The groove 3013 is designed to avoid the mounting plate 202, preventing it from encroaching on the position of the sealing cylinder 301, thereby preventing the probe 104 from deviating from its position. The top of the slide block 201 is fitted with a limit bolt 602. The limit rod 601 is slidably connected to the sealing cylinder 301. The limit rod 601 and the T-shaped slide groove 1011 are marked with scales 603, which can help the operator clearly understand the position of the probe 104. One side of the slide 201 is fixed to the limit block 702 through the bent tube 701. The limit block 702 is threadedly connected to the limit screw 703. The limit screw 703 abuts against the base 101, which can easily fix the slide 201, and thus fix the probe 104.
[0024] The working principle of this utility model is as follows: First, according to the number of holes to be tested on the circuit board, a corresponding number of sealing cylinders 301 are installed on the corresponding bidirectional threaded rods 203. The position of the sealing cylinders 301 can be precisely controlled by the scale 603 on the limiting rod 601. Then, the slide block 201 is slid into the corresponding T-shaped slide groove 1011. The position of the slide block 201 can be precisely controlled by the scale 603 on the T-shaped slide groove 1011. Then, the limiting screw 703 is rotated to make the limiting screw 703 abut against the base 101, thereby fixing the probe 104. In this way, it can flexibly adapt to circuit boards of different specifications and sizes, and facilitate quick adjustment and switching of different circuit boards. During the circuit board inspection, the operator places the circuit board vertically onto the probe 104. If all the holes are aligned correctly, the alarm 502 will not sound. If there is a deviation in the hole alignment, the circuit board will press against the probe 104, causing the probe 104 to press against the mounting base 302. The mounting base 302 will then press against the hydraulic oil, which in turn will press against the piston plate 303. This will cause the elastic element 304 to store elastic potential energy. When the displacement detector 501 detects the displacement of the piston plate 303, it will transmit a signal to the external controller. The external controller will then activate the corresponding alarm 502, causing the alarm 502 to sound to alert the operator.

Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
