The circuit board is divided into three large categories of a single-sided board, a double-sided board and a multi-layer circuit board according to the number of layers.

[0003] In the process of processing the PCB, in order to enable the PCB to realize certain specific functions, the PCB needs to be programmed. Before starting the programming, in order to ensure the normal programming, the PCB needs to be tested for qualification, and then a suitable programming method is selected. Generally, the qualification of the PCB is detected by using a PCB test module.

[0039] With reference to Figure 2 and Figure 4 The pushing assembly 5 is arranged on the detection support 1. The pushing assembly 5 comprises a linkage rod 51, a sliding ring 52, a pushing plate 53, a supporting plate 54, a pushing spring 55, a linkage slide rod 56 and a linkage limiting block 57.

[0040] With reference to Figure 1 and Figure 3 When the circuit board is detected, one side of the circuit board is abutted against the clamping top plate 31 and the circuit board is pressed downward. With the downward pressing of the circuit board, the sliding clamping rod 33 slides away from the fixed clamping rod 32. When the circuit board moves to the clamping wedge block 35 and abuts against the top end of the detection needle 25, the sliding clamping rod 33 moves toward the fixed clamping rod 32 under the action of the clamping spring 34. The fixed clamping rod 32 and the clamping wedge block 35 on the sliding clamping rod 33 simultaneously limit the circuit board, so that the rapid positioning of the circuit board is realized.

[0041] With reference toFigure 1 And Figure 3 The detection cylinder 21 is started and drives the moving plate 22 and the upper detection plate 23 arranged thereon to move downward until the detection needle 25 arranged on the upper detection plate 23 contacts the circuit board, thereby achieving detection of the circuit board. The arrangement of the two sets of detection assemblies 2 enables the device to detect two circuit boards at a time, thereby improving the detection efficiency of the device. After detection is completed, the moving plate 22 moves upward, and the detection needle 25 on the upper detection plate 23 is separated from the circuit board.

[0042] Referring to Figures 2-4 The operator pulls the push-pull slide plate 46 away from the mounting back plate 104, and the ejection spring is elongated to accumulate elastic potential energy. The ejection slope 481 of the ejection inclined block 48 abuts against the abutting block 43. The lifting rod 42 and the lifting plate 41 arranged at the top end of the lifting rod 42 move upward, the lifting plate 41 pushes the circuit board upward, and the sliding clamping rod 33 moves away from the fixed clamping rod 32 under the pushing of the lifting plate 41 and the guidance of the clamping slope 36, until the circuit board is ejected between the fixed clamping rod 32 and the sliding clamping rod 33, and the lifting spring 44 is compressed to accumulate elastic potential energy. The arrangement of the ejection assembly realizes rapid ejection of two circuit boards.

[0043] Referring to Figures 2-4 The linkage slide rod 56 moves with the ejection inclined block 48, and when the linkage slide rod 56 moves to the linkage limiting block 57 in contact with the sliding ring 52, the linkage rod 51 and the pushing plate 53 move synchronously with the linkage slide rod 56, and the pushing spring 55 is elongated to accumulate elastic potential energy. The pushing plate 53 pushes the circuit board above the lower detection plate 24 to fall on the detection support 1, thereby realizing rapid and continuous ejection of the circuit board and improving the detection efficiency of the device.

[0044] Referring to Figures 2-4 After the ejection of the circuit board is completed, the operator releases the push-pull slide plate 46. The arrangement of the ejection spring realizes automatic resetting of the push-pull slide plate 46, and the lifting rod 42 and the lifting plate 41 are lowered to realize resetting under the action of the lifting spring 44. The pushing plate 53 moves out of the upper side of the lower detection plate 24 under the action of the pushing spring 55, thereby facilitating the next ejection operation of the circuit board.

[0045] The implementation principle of the PCB detection module facilitating discharging in the embodiment of the application is as follows: when the circuit board is detected, one side of the circuit board is abutted against the clamping top plate 31 and the circuit board is pressed downward. The clamping wedge blocks 35 on the fixed clamping rods 32 and the sliding clamping rods 33 simultaneously limit the circuit board, so that the circuit board is quickly positioned. The upper detection plate 23 moves downward until the detection needle 25 contacts the circuit board, so that the circuit board is detected. The push-pull slide plate 46 is pulled, the inclined block 48 is ejected to drive the lifting plate 41 to move upward, the lifting plate 41 pushes the circuit board upward, the circuit board is ejected between the fixed clamping rods 32 and the sliding clamping rods 33, and the circuit board is quickly discharged. The linkage rod 51 and the pushing plate 53 move synchronously along with the linkage slide rod 56, the pushing plate 53 pushes the detection support 1 to fall, and the circuit board is quickly and continuously discharged.
