[0012] An emergency light circuit board detection device and a process thereof, the detection process comprising the following steps:

[0013] The first step is to place the circuit board to be tested horizontally in the placement slot on the mounting table. At this time, the lifting electric cylinder drives the lifting frame to move up and down on the support frame. During the downward movement, the flip motor drives the flip plate to rotate on the flip seat, and the flip plate is rotated from a folded state to an extended state, and the flip plate is extended outward and moved above the circuit board. At this time, the lifting frame moves downward to drive the fixing rod to move downward, so that the fixing rod contacts the circuit board, and the circuit board is limited in the placement slot;

[0014] In the second step, when the circuit board is limited, the positions of the two detection mechanisms can be adjusted according to the size of the circuit board. At this time, the two-way electric slide can be driven to adjust the positions of the two detection mechanisms, and the positions of the two detection mechanisms are adjusted to the two ends of the circuit board and the circuit board is adjusted;

[0015] In the third step, after the position of the circuit board is limited, when different positions on the circuit board need to be inspected, the telescopic end of the flip electric cylinder moves to drive the position of the rotating plate to rotate on the flip plate, thereby driving the position of the rotating plate to be adjusted and rotated, and the position of the detection rod is moved to the top of the solder joints and electrical components to be inspected on the circuit board, and the circuit board is inspected;

[0016] In the fourth step, the moving motor drives the moving gear to rotate on the moving tooth plate on the moving slider, thereby driving the moving slider to move horizontally at the position of the rotating plate. When different positions on the circuit board are detected, the position of the moving slider can be moved forward and extended, and the position of the detection rod can be adjusted according to the needs of the detection;

[0017] Step 5: When there is no need to move the detection rod forward by moving the motor, and only the position adjustment is required at the distance of the flip plate, the slide table can be moved horizontally to drive the detection rod to move and adjust the detection position;

[0018] The sixth step is to adjust the position of the detection rod, and then move the detection rod downward by moving the detection electric cylinder downward, and move the detection rod to the circuit board to detect the solder joints and electrical components on the circuit board, to detect whether the solder joints and electrical components of the circuit board are qualified and whether there is a short circuit, and to sound an alarm through the detection alarm light.

[0019] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0020] Firstly, after the position of the circuit board is limited, when different positions on the circuit board need to be detected, the telescopic end of the flip electric cylinder moves to drive the position of the rotating plate to rotate on the flip plate, thereby driving the position of the rotating plate to be adjusted and rotated, and the position of the detection rod is moved to above the solder joints and electrical components to be detected on the circuit board, and the circuit board is detected; the mobile motor drives the moving gear to rotate on the moving tooth plate on the moving slider, thereby driving the moving slider to move horizontally at the position of the rotating plate. When different positions on the circuit board are detected, the position of the moving slider can be moved forward and extended, and the position of the detection rod can be adjusted according to the needs of the detection; when it is not necessary to drive the position of the detection rod to move forward by the mobile motor, and only the position needs to be adjusted at the distance of the flip plate, the horizontal moving slide can be used to drive the position of the detection rod to move and adjust the detection position. In the present invention, when the circuit board is detected, the detection position can be adjusted according to the needs of the detection, thereby ensuring the comprehensiveness of the detection.

[0021] Secondly, the present invention places the circuit board to be inspected horizontally in the placement groove on the mounting table, and at this time, the lifting electric cylinder works to drive the lifting frame to move up and down on the support frame. During the downward movement, the flip motor works to drive the flip plate to rotate on the flip seat, and the flip plate is rotated from a folded state to an extended state, and the flip plate is extended outward and moved to above the circuit board. At this time, the lifting frame moves downward and drives the fixing rod to move downward, so that the fixing rod contacts the circuit board, and the circuit board is limited in the placement groove, and the position of the circuit board is limited and fixed to prevent the position of the circuit board from shifting during the inspection of the circuit board, which affects the accuracy of the inspection.

[0022] Thirdly, the present invention is provided with a detection mechanism, which can realize double-station detection operation when detecting the circuit board, thereby improving the detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
