Description

Technical Field

[0001] The present application relates to the technical field of circuit detection, and more specifically, to a circuit board function detection device. Background Art

[0002] Circuit boards are also called printed circuit boards or printed circuit boards. They are important electronic components, supporting electronic components and serving as carriers for electrical connections of electronic components. Circuit boards miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and in optimizing the layout of electrical appliances.

[0003] The working principle of a circuit board is to use the board-based insulating material to isolate the surface copper foil conductive layer, so that the current flows along the pre-designed route in various components to complete functions such as work, amplification, attenuation, modulation, demodulation, encoding, etc. When the electrical signal of a certain function of a multi-layer circuit board passes through components, vias and other circuits, it will mistakenly connect to the circuits of other functions and interfere with the tested electrical signal. Especially with the advancement of modern technology and the increase in demand for circuit board functions, the circuits of the circuit board are usually distributed at both ends of the circuit board, and one-sided detection cannot detect them. Only single-sided detection will result in poor detection results and distorted detection results. Therefore, the detection of the connectivity status of the circuit board usually requires double-sided detection of the circuit board.

[0004] At present, most circuit board detection methods on the market only support single-sided detection, which cannot realize separate detection of circuits on both sides of the circuit board, and is prone to interference. The utility model patent with publication number CN119936034 discloses a double-sided detection solution, which adopts the following technical solution: installing detection equipment at the circuit board tooling position, and detecting the circuit board through two sets of detection equipment, which not only increases the detection cost, but more importantly, the detection structure relies on two sets of detection equipment to achieve detection accuracy, and the detection efficiency is low.

[0047] The present application integrates the functions of circuit board positioning and insertion, overall flipping of the plug-in board assembly 2 and circuit detection, thereby realizing double-sided detection of the circuit board and improving detection accuracy and detection efficiency.

[0048] refer to Figure 2 . In a specific embodiment, the slot body includes: a slot 211, two card plates 212, a slide 213 and a retreat groove. The slot 211 is arranged on the inner wall of the placement rack 21, specifically on the central axis of the front side of the inner wall of the placement rack 21, and the circuit board can be inserted into the slot to achieve the placement of the circuit board. The two card plates 212 are distributed on the left and right inner walls of the placement rack 21, and are distributed on the upper and lower sides of the slot 211. The interval between the two card plates 212 is equal to the thickness of the circuit board, so as to enhance the fixing effect of the circuit board. The slide 213 is arranged on the rear side of the inner wall of the slot body, and the slide 213 allows the circuit board to slide into the card plate 212. After the circuit board is inserted, the upper and lower card plates 212 clamp the circuit board, and continue to slide the circuit board, and slide the circuit board into the slot to achieve the fixation of the circuit board.

[0049] The middle of the card slot is connected to a withdrawal slot, and the slot 211 can be used by a hand or a card removal device to withdraw the circuit board from the slot 211.
