[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0017] First, combine Figures 1-4 This invention describes an offline high-speed testing device for wire terminals, which is used for high-speed testing of wire terminals and has a wide range of applications.

[0020] Specifically, such as Figure 1 As shown, the loading module 300 is located on one side of the machine base 100; the loading module 300 includes: a first four-axis robot arm, which is disposed on one side of the machine base 100 and is used to transfer the wire terminals on the external loading station to the conveyor belt 200. The first four-axis robot arm is a SCARA robot arm.

[0021] Specifically, such as Figure 1 As shown, the first CCD detection structure 400 is set on the machine tool 100 for taking pictures and detecting one side of the wire terminal.

[0022] Specifically, such as Figures 1-4 As shown, a flipping module 500 is mounted on the machine base 100 and is used to flip wire terminals. The flipping module 500 includes a first flipping unit and a second flipping unit. The first flipping unit is mounted on the machine base 100 and is used to flip the wire terminals on the machine base 100 by 90°. The second flipping unit is mounted on the machine base 100 and located to one side of the first flipping unit, and is used to receive the wire terminals flipped by the first flipping unit and flip the wire terminals by 90°.

[0023] Furthermore, such as Figures 1-4As shown, the first flipping unit includes: a lifter 511, a motor 512, and a cross-shaped swing arm 513. The lifter 511 is mounted on the machine base 100 and provides the driving force for the lifting motion; the lifter 511 can be a lifting cylinder. The motor 512 is located at the output end of the lifter 511. The cross-shaped swing arm 513 is connected to the output end of the motor 512, and each of its four ends is equipped with a first suction head. By controlling the operation of the lifter 511, the cross-shaped swing arm 513 descends towards the wire terminal on the conveyor belt 200 and contacts the wire terminal. The wire terminal is then attracted by the first suction head. Then, by controlling the operation of the lifter 511 in the reverse direction, the cross-shaped swing arm 513 and the attracted wire terminal rise to a suitable height. The motor 512 is then controlled to rotate the cross-shaped swing arm 513 and the attracted wire terminal by 90°.

[0024] Furthermore, such as Figures 1-4 As shown, the second flipping unit includes: a first fixed block 521, a connecting rod 522, a telescopic cylinder 523, a second fixed block 524, a movable block 525, and an L-shaped rod 526. The first fixed block 521 is mounted on the machine base 100; one end of the connecting rod 522 is hinged to the first fixed block 521; one end of the telescopic cylinder 523 is hinged to the machine base 100, and the other end of the telescopic cylinder 523 is hinged to the connecting rod 522; the second fixed block 524 is mounted on the machine base 100; the movable block 525 is hinged to the second fixed block 524, and the movable block 525 has a through hole; one end of the L-shaped rod 526 passes through the through hole in the movable block 525, and the other end of the L-shaped rod 526 passes through the other end of the connecting rod 522, and the L-shaped rod 526 has a second suction head. By controlling the telescopic cylinder 523, the connecting rod 522 can be driven to rotate around its hinge point with the first fixed block 521, and the L-shaped rod 526 can be driven to move. The L-shaped rod 526 changes direction under the action of the movable block 525, so that the second suction head on the L-shaped rod 526 contacts and receives the wire terminal adsorbed by the first suction head on the cross swing arm 513. After receiving the wire terminal, by controlling the telescopic cylinder 523 to run in the opposite direction, the L-shaped rod 526 runs in the opposite direction, flipping the wire terminal adsorbed by the second suction head by 90°, and then dropping it onto the conveyor belt 200.

[0025] Specifically, such as Figure 1 As shown, the second CCD detection structure 600 is installed on the machine tool 100 and is used to take pictures and detect the other side of the guide terminal.

[0026] Specifically, such as Figure 1 As shown, the unloading mold is located on one side of the machine base 100. The unloading module 700 includes a second four-axis robot arm, which is set on one side of the machine base 100 and is used to transfer the inspected wire terminals on the conveyor belt 200 to the receiving station or NG station. The second four-axis robot arm is a SCARA robot arm.

[0027] Working principle: The blister packs filled with wire terminals to be inspected are pre-placed at the loading station. A four-axis robotic arm positions and picks up the terminals, placing them onto conveyor belt 200. Conveyor belt 200 delivers the wire terminals to the first CCD inspection structure 400 for image inspection. After inspection, a high-speed flipping module 500 quickly reverses the wire terminals, and conveyor belt 200 continues to transport the products to another CCD inspection structure for image inspection of the other surface of the wire terminals. After system recognition, a second four-axis robotic arm places OK products at the receiving station and NG products at the NG station.

By adopting an offline method and in conjunction with a high-speed flip module 500, the detection cycle can be completed quickly, improving efficiency.

[0029] 2. The entire detection process takes approximately 2-3 seconds. This is significantly more efficient than the typical 8-10 second cycle time of online detection.
