Description

Technical Field

[0001] This utility model relates to the field of copper thickness measurement technology for circuit boards, and in particular to a positioning device for a copper thickness measuring instrument. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), copper layer thickness is a critical parameter that directly affects the electrical performance, signal transmission quality, and lifespan of the PCB. To ensure that the quality of the PCB meets standards, accurate measurement of copper layer thickness is necessary. Existing copper thickness measuring instruments all use dedicated positioning devices, meaning that each positioning device can only measure the copper thickness of one set of part numbers. This increases manufacturing costs and wastes human resources for fixtures that need to be measured for multiple part numbers. Furthermore, it requires a large space to store the fixtures, increasing storage and management costs. Additionally, the measuring head of the instrument is not effectively protected when in contact with the circuit board, making it susceptible to damage.

[0003] Existing technology CN219161253U discloses a positioning device for a rigid circuit board copper thickness measuring instrument, including a measuring table, a transverse clamping module sliding longitudinally above the measuring table, a longitudinal clamping module slidingly mounted on the transverse clamping module, a measuring instrument for measurement mounted above the measuring table, and a fixing module installed between the measuring instrument and the measuring table. The transverse clamping module includes a transverse retraction rod, a sliding frame symmetrically slidably connected to the transverse retraction rod, and a transverse clamping block installed on the inner side of the sliding frame. The longitudinal clamping module includes a longitudinal retraction rod, and longitudinal clamping blocks symmetrically arranged on the longitudinal retraction rod. This utility model, by using multiple sets of clamping modules to move along the X / Y axes on the measuring table, thereby changing the size of the positioning space formed between the unit clamping modules, can meet the requirements for measuring the copper thickness of different material grades, greatly reducing the cost of manufacturing fixtures, saving storage space, and reducing management costs.

[0004] While the aforementioned positioning device for measuring copper thickness on rigid circuit boards can locate the circuit board, its structure is relatively complex, its manufacturing cost is high, and it is inconvenient for later maintenance. Utility Model Content

The first sliding member is mounted on the placement platform and supports the first corner bracket. The second corner bracket is slidably connected to the placement platform via the second sliding member. The second sliding member is mounted on the placement platform and supports the second corner bracket. The adjusting member drives the first corner bracket and the second corner bracket to move.

[0007] The first sliding component includes a first slider and a first mounting plate. The first slider is slidably connected to the placement platform and is located on the side of the placement platform near the first corner bracket. The first mounting plate is fixedly connected to the first slider, and the first corner bracket is detachably mounted on the first mounting plate.

The second slider is slidably connected to the placement platform and is located on the side of the placement platform near the second corner bracket. The second mounting plate is fixedly connected to the second slider, and the second corner bracket is detachably mounted on the second mounting plate.

The first slider 106 is slidably mounted on the placement platform 103 through the sliding groove 104. The first mounting plate 107 is a rectangular plate located on top of the first slider 106. The first corner bracket 105 is mounted on the first mounting plate 107 by bolts. When the first corner bracket 105 is worn, it is easy to replace. Through the first slider 106 and the first mounting plate 107, the first corner bracket 105 can slide on the placement platform 103.

[0026] Finally, the support column 113 is threadedly connected to the placement platform 103 and located on top of the placement platform 103. The support column 113 is a cylinder with a thread at the bottom end. There are multiple support columns 113. The top of the placement platform 103 is provided with several threaded holes 114. The support column 113 is installed on the placement platform 103 through the threaded holes 114. After the support column 113 is installed, the top of the support column 113 is flush with the top surfaces of the first mounting plate 107 and the second mounting plate 110. The support column 113 can be installed by selecting the appropriate threaded holes 114 according to the size of the circuit board. Through the support column 113, stable support can be provided for the middle part of the circuit board.

[0027] In this embodiment, during use, multiple support columns 113 are installed in appropriate positions according to the size of the circuit board. Then, the circuit board is placed on the support columns 113.
