[0033] In this embodiment, when measuring the electrical parameters of the circuit board, the circuit board body 202 is inserted into the frame 201 for placement. After the motor 103 is started, the bidirectional screw rod 104 can be driven to rotate. The rotation of the bidirectional screw rod 104 can drive the sliding seats 301 on both sides to move relative to the frame 201. At this time, the connecting seats 308 on both sides move relative to the frame 201. The measuring plates 310 and the positioning frames 312 on both sides are respectively in a state of fitting with the two side surfaces of the circuit board body 202. The measuring plate 310 fits with one side surface of the circuit board body 202, and the circuit board body 202 can be measured. 2 is connected to the front contact or the back solder joint of the circuit board body 202, so as to realize the measurement of the electrical parameters of the circuit board body 202. For the coordinated use of the positioning frame 312 on the other side, the coordinated setting of the positioning frame 312 and the second frame rod 311 makes the fixing plate 313 and the circuit board body 202 maintain a certain distance. At this time, the camera 314 can be used to capture the surface image of the circuit board body 202. By transmitting the captured image of the circuit board body 202 to the system, the surface visual defect detection of the circuit board body 202 can be realized.

[0034] Embodiment 2

[0035] Figure 4 and Figure 8As shown, the circuit board body 202 is located at the inner side of the frame 201, washers 203 are arranged on the inner surfaces of both sides of the frame 201, the outer surfaces of the washers 203 are fitted with the outer surface of the circuit board body 202, a notch 204 is opened on the top of the frame 201, a support plate 502 is fixedly connected to the top of the support rod 501, an electric push rod 503 is fixedly connected to the bottom of the support plate 502, a wedge 504 is fixedly connected to the lower end surface of the electric push rod 503, the wedge 504 is matched with the position of the notch 204, the wedge 504 is inclined on the side facing the circuit board body 202, and the thickness of the wedge 504 is consistent with that of the circuit board body 202.

[0036] In this embodiment, after completing the measurement of both sides of the circuit board body 202, the motor 103 is started to drive the support 307 to move outward and reset, and then the electric push rod 503 is started to extend.

After the wedge block 504 moves downward, it can be inserted into the frame 201 through the slot 204. At this time, the inclined surface of the wedge block 504 will contact the circuit board body 202. As the wedge block 504 continues to move downward, the wedge block 504 can squeeze the circuit board body 202 out of the frame 201.

[0037] Embodiment 3

[0038] Figure 3 and Figure 5 As shown, the outer surface of the support 307 located on one side of the measuring plate 310 is fixedly connected to the side plate 303, the outer surface of the side plate 303 is fixedly connected to the cross plate 304, the cross plate 304 is located at the lower side of the gear ring 412, the top of the cross plate 304 is fixedly connected to the tooth block 305, the tooth block 305 is meshingly connected to the gear ring 412, and the bottom of the cross plate 304 is symmetrically fixedly connected to the second slider 306, and the outer surface of the second slider 306 is slidably connected to the inner surface of the second slide rail 106.

[0039] In this embodiment, when the support 307 is displaced and drives the cross plate 304 to follow the movement, the cross plate 304 will drive the second slider 306 to follow the movement, and the second slider 306 will move along the second slide rail 106. At this time, the second slide rail 106 and the second slider 306 are matched to support and limit the position of the cross plate 304, thereby ensuring that the displacement state of the cross plate 304 is stable, and the tooth block 305 and the gear ring 412 are stably engaged to achieve driving, thereby improving the stability of the device operation.

[0040] The use method and working principle of the device are as follows: when measuring the electrical parameters of a circuit board, the circuit board body 202 is inserted into the frame 201 for placement. The setting of the washers 203 on both sides of the frame 201 can play a filling role, so that the circuit board body 202 and the washers 203 are tightly fitted and placed inside the frame 201 for measurement. When the measurement starts, the circuit board body 202 is in a vertical state, and the connecting seats 308 on both sides are away from the frame 201. At this time, the motor 103 is started to run. After the motor 103 is started, the bidirectional screw rod 104 can be driven to rotate. Through the rotation of the bidirectional screw rod 104, the sliding seats 301 on both sides can be driven to move relative to the frame 201. When the sliding seats 301 move, the sliding The seat 301 can drive the first slider 302 to follow the movement through the connection of the support 307. The first slider 302 will slide on the inner wall of the first slide rail 105. The first slider 302 and the first slide rail 105 are matched to support and limit the displacement of the support 307. The movement of the support 307 can drive the connecting seat 308 to follow the movement. At this time, the connecting seats 308 on both sides move relatively toward the frame 201. After completing a certain distance of displacement, the measuring plates 310 and the positioning frames 312 on both sides are respectively in a state of fitting with the two side surfaces of the circuit board body 202. At this time, through the matching use of the measuring plate 310 and the positioning frame 312, the measuring plate 310 fits with one side surface of the circuit board body 202, and the electrical The front contact or the back solder joint of the circuit board body 202 is connected to realize the electrical parameter measurement of the circuit board body 202. For the coordinated use of the positioning frame 312 on the other side, the coordinated setting of the positioning frame 312 and the second frame rod 311 makes the fixing plate 313 maintain a certain distance with the circuit board body 202. At this time, the camera 314 can be used to capture the surface image of the circuit board body 202. By transmitting the captured image of the circuit board body 202 to the system, the surface visual defect detection of the circuit board body 202 can be realized. At this time, the two sides of the circuit board body 202 are synchronously in the detection state, one side completes the electrical parameter measurement, and the other side completes the visual defect detection. After completing the measurement of the circuit board body 202 in the current state, The starting motor 103 drives the bidirectional screw rod 104 to reverse, and the rotation of the bidirectional screw rod 104 can drive the supports 307 on both sides to move away from the frame 201. When the supports 307 move outward, the supports 307 will drive the cross plate 304 and the tooth block 305 to follow the displacement through the connection of the side plate 303. After the cross plate 304 is displaced so that the tooth block 305 and the gear ring 412 are in a meshing state, the translation of the cross plate 304 can drive the gear ring 412 to rotate. When the gear ring 412 rotates, it will drive the spring 414, the telescopic rod 415 and the block 416 to follow the rotation. At this time, the vertical surface of the block 416 is in a fit state with the vertical surface of the ratchet 413, so the gear ring 412 can drive the ratchet 413 to rotate in the same direction.When the ratchet 413 rotates, it drives the first connecting shaft 403 to rotate accordingly. When the first connecting shaft 403 rotates, it can drive the second connecting shaft 404 to rotate accordingly through the connection of the first pulley 405, the belt 407 and the second pulley 406. The rotation of the second connecting shaft 404 can drive the second mounting plate 408 and the two mounting rods 409 to rotate accordingly. Since the mounting rods 409 and the frame 201 are in a fixed state, the rotation of the second connecting shaft 404 can drive the frame 201 and the internal circuit board body 202 to rotate. After the support 307 moves to the outermost side, the displacement of the tooth block 305 drives the second connecting shaft 404 to complete a 180-degree rotation. The circuit board body 202 will be flipped over. At this time, the side of the circuit board body 202 that has completed the connection measurement is facing the camera 314, and the side that has completed the visual inspection of the camera 314 is facing the measuring board 310. Then, the motor 103 is started to measure the circuit board body 202. After the motor 103 is running, it can drive the supports 307 on both sides to move toward the side of the frame 201. Then, the measuring board 310 and the positioning frame 312 continue to move to a state of fitting the surface of the circuit board body 202. Since the position of the circuit board body 202 has been flipped over, the electrical parameter measurement and visual defect inspection of both sides of the circuit board body 202 are completed at this time. Through the cooperation of the support component 1, the placement component 2, the measurement component 3 and the switching component 4 In use, the circuit board body 202 can be automatically flipped to realize electrical parameter measurement and visual defect detection on both sides, and it has a high degree of automation. When the support 307 moves toward one side of the frame 201, the tooth block 305 continues to mesh with the tooth ring 412, and the tooth ring 412 rotates in the opposite direction compared to the outward state of the support 307. At this time, when the tooth ring 412 drives the card block 416 to follow the rotation, the inclined surface of the card block 416 is in contact with the inclined surface of the ratchet 413, so at this time the ratchet 413 will push the card block 416 to move to the side of the spring 414, and the spring 414 will shrink after being compressed. The setting of the telescopic rod 415 cooperates to support and limit the displacement of the card block 416. At this time, as the card block 416 is deformed, the tooth ring 412 When the ratchet wheel 413 is rotated, the ratchet wheel 413 does not rotate, that is, the flip position of the frame 201 does not change. When the support 307 is displaced and the cross plate 304 is driven to move, the cross plate 304 will drive the second slider 306 to move, and the second slider 306 will move along the second slide rail 106. At this time, the second slide rail 106 and the second slider 306 are matched to support and limit the position of the cross plate 304, so as to ensure that the displacement state of the cross plate 304 is stable, and the tooth block 305 and the tooth ring 412 are stably engaged to realize the drive, thereby improving the stability of the device operation. After completing the measurement of both sides of the circuit board body 202, the motor 103 is started to drive the support 307 to move outward and reset, and then the electric push rod 503 is started to extend.After the electric push rod 503 is extended, it can drive the wedge block 504 to move downward. After the wedge block 504 moves downward, it can be inserted into the frame 201 through the slot 204. At this time, the inclined surface of the wedge block 504 will contact the circuit board body 202. As the wedge block 504 continues to move downward, the wedge block 504 can squeeze the circuit board body 202 out of the frame 201.
