DETAILED DESCRIPTION

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0036] This embodiment provides a fully automatic visual inspection machine for connectors, which realizes the inspection and processing of docking connectors, ensuring 100% inspection of connectors. At the same time, the inspection accuracy is greatly improved compared with visual inspection, thereby eliminating misjudgment and missed inspection due to human factors, ensuring the consistency of connectors, and greatly improving the stability, quality and performance of connectors.

[0037] Combine Figures 1 to 7 As shown, the fully automatic visual inspection machine for connectors of this embodiment includes an inspection turntable 10 and a loading part 20, an inspection part 30 and an unloading part 40 arranged in sequence along the driving direction of the inspection turntable 10. The inspection turntable 10 drives the connector to rotate, and the loading part 20, the inspection part 30 and the unloading part 40 can perform loading, inspection and unloading operations on the connector in sequence.

[0038] In this embodiment, the fully automatic visual inspection machine for connectors also includes a base plate 50, and the inspection turntable 10, the loading part 20, the inspection part 30 and the unloading part 40 are all arranged on the base plate 50. A driving motor is provided on the base plate 50 to drive the inspection turntable 10 to rotate. The inspection turntable 10 of this embodiment is connected to the driving motor through a cam divider, and the driving motor drives the inspection turntable 10 through the cam divider.

[0039] Combine Figure 1 and Figure 2As shown, a plurality of carriers 11 are provided on the inspection turntable 10 of this embodiment to carry and install the connectors. Part of the carriers 11 protrudes from the edge of the inspection turntable 10. The part of the carriers 11 protruding from the edge of the inspection turntable 10 is used to load the connectors so that the connectors can be subsequently inspected.

[0040] In this embodiment, the carrier 11 includes an upload block 111 and a download block 112. The upload block 111 is connected to the detection turntable 10 through the download block 112. A positioning cavity is provided on the upload block 111 to position the connector. The positioning cavity protrudes from the edge of the detection turntable 10. The upload block 111 of this embodiment is an anti-static PEEK material block, and the download block 112 is a metal block. The upload block 111 is installed on the detection turntable 10 by the download block 112, and the positioning cavity of the upload block 111 stably positions the connector for subsequent connector detection.

[0041] Specifically, a hollow structure is provided on the download block 112, and the hollow structure overlaps with the positioning cavity so as to detect the reverse side of the docking plug-in. The presence of the positioning cavity and the hollow structure enables the portion of the connector to be detected after positioning to protrude 30 points from the edge of the detection turntable 10, thereby ensuring stable detection of the docking plug-in while the docking plug-in is being positioned.

[0042] like Figure 1 As shown, the loading part 20 of this embodiment moves the connector to be inspected into the carrier 11, and the unloading part 40 moves the inspected connector out of the carrier 11. The loading part 20 includes a loading robot arm 21 and a loading bin 22, and the unloading part 40 includes a unloading robot arm 41 and a unloading bin 42. Both the loading bin 22 and the unloading bin 42 are provided with material trays. During the loading process, the loading robot arm 21 moves the connector in the material tray of the loading bin 22 into the carrier 11. After the connector inspection is completed, the unloading robot arm 41 moves the connector into the material tray located in the unloading bin 42 to complete the inspection and unloading of the connector.

[0043] Further integration Figure 1 and Figure 7 As shown, a transfer part 60 is provided on the bottom plate 50, and the transfer part 60 is located between the loading bin 22 and the unloading bin 42, and transfers the material tray. The transfer part 60 includes a transfer module 61, a transfer cylinder 62 and a suction cup 63. The transfer cylinder 62 drives the suction cup 63 to adsorb the material tray, and the transfer module 61 drives the transfer cylinder 62 to move. In actual use, when the transfer part 60 is in full use, after all the connectors in the material tray of the loading bin 22 are taken out, the suction cup 63 is driven by the transfer cylinder 62 of the transfer part 60 to adsorb the material tray, and the material tray is transferred to the unloading bin 42 under the action of the transfer module 61, waiting for the unloading of the docking plug-in. Therefore, the existence of the transfer part 60 can quickly transfer the material tray, improve the use efficiency of the material tray, and thereby improve the detection efficiency of the docking plug-in.

[0044] like Figure 1 As shown, the detection portion 30 of this embodiment includes a first detection mechanism 31, a second detection mechanism 32, a third detection mechanism 33 and a fourth detection mechanism 34 which are sequentially arranged along the driving direction of the detection turntable 10, and perform sinking detection, front detection, reverse Z-direction detection and reverse XY-direction detection on the docking plug-in in sequence. The first detection mechanism 31, the second detection mechanism 32, the third detection mechanism 33 and the fourth detection mechanism 34 which are sequentially arranged in this embodiment realize continuous detection of the docking plug-in, which improves the detection effect and can also effectively improve the detection efficiency.

[0045] Specific combination Figures 3 to 6 As shown:

[0046] The first detection mechanism 31 of this embodiment includes a first driver 311, a displacement sensor 312, and an amplifier 313. The first driver 311 drives the displacement sensor 312 to detect the connector. When the connector to be tested in the carrier 11 passes through the detection turntable 10 and reaches the first detection position, the first driver 311 drives the displacement sensor 312 to perform a downward test. The data detected by the displacement sensor 312 is compared with the set value to determine whether it is qualified. Under the amplification effect of the amplifier 313, the detection accuracy is improved. The first driver 311 of this embodiment is a cylinder.

[0047] The second detection mechanism 32 of this embodiment includes a second driver 321 and a second camera 322. The second driver 321 drives the second camera 322 to detect the docking plug-in. The second driver of this embodiment drives the KK module through a servo motor to drive the second camera 322 to move, and performs omnidirectional visual inspection at different heights on the connector. The qualified status can be determined by comparing the data recognized by taking photos with the set data. The second camera 322 of this embodiment is an industrial camera and is equipped with a lens and a light source to achieve omnidirectional visual inspection of the docking plug-in.

[0048] The third detection mechanism 33 of this embodiment includes a third driver 331, a rotating table 332 and a third camera 333. The third camera 333 is arranged on the rotating table 332 and is driven to rotate by the rotating table 332. The third driver 331 drives the rotating table 332. The third driver 331 of this embodiment drives the KK module through a servo motor to drive the rotating table 332 and the third camera 333 to move, and the rotating table 332 can realize the rotational drive of the third camera 333. In this process, the back bending Pin Z-direction position measurement of the docking plug-in is realized. The qualified status can be determined by comparing the recognized data with the set data. The third camera 333 of this embodiment is a 3D line scan camera.

[0049] The fourth detection mechanism 34 of this embodiment includes a positioning structure 341 and a fourth camera 342. After the positioning structure 341 positions the connector, the fourth camera 342 docks the connector for detection. Since the reference camera capture of the connector itself is unclear, it is necessary to increase the positioning mechanism for positioning when performing bending Pin XY position detection to facilitate visual capture. After the carrier 11 reaches the fourth detection position, the positioning structure 341 docks the connector for positioning. After positioning, the fourth camera 342 docks the connector for detection. After taking the picture, it automatically identifies and calculates the data, and compares it with the set data to determine whether it is qualified. The fourth camera 342 of this embodiment is an industrial camera, and is equipped with a lens and a light source to realize the detection of docking connectors.

[0050] Specifically, the positioning structure 341 of this embodiment includes a main positioning cylinder 3411 and an auxiliary positioning cylinder 3412. The piston rod end of the main positioning cylinder 3411 is provided with a spring pin 70. The main positioning cylinder 3411 drives the spring pin 70 to be inserted from the upper part of the connector to position the connector. There are two auxiliary positioning cylinders 3412 and the piston rod end is provided with a reference pin 80. The auxiliary positioning cylinder 3412 drives the reference pin 80 to be inserted from the lower part of the connector to position the connector.

[0051] In actual use, the fully automatic visual inspection machine for connectors of this embodiment loads the connectors to be inspected by the loading unit 20, stably positioning the connectors within the carrier 11. The carrier 11 then rotates on the inspection turntable 10 and sequentially passes through the first inspection mechanism 31, the second inspection mechanism 32, the third inspection mechanism 33, and the fourth inspection mechanism 34 of the inspection unit 30, respectively completing sinking inspection, front inspection, back Z-direction inspection, and back XY-direction inspection of the connectors. After the inspections are complete, the unloading unit 40 unloads the inspected connectors.

[0052] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
