[0030] In this embodiment, refer to Figures 1-5The specific implementation of the automatic feeding device with secondary visual detection includes a support plate 1, a rotating disc 3 connected with the support plate 1 through a lifting divider 2, and a driving element for providing a power source for the lifting divider 2 arranged on the support plate 1.

[0032] Ten clamps 4 are distributed along the circumferential direction on the rotating disc 3. Specifically, the clamp 4 is composed of a negative pressure suction nozzle, and a vacuum air source 12 for providing a negative pressure suction force for the negative pressure suction nozzle is connected with the support plate 1 through a support frame 11.

[0033] The support plate 1 is sequentially provided with a feeding station, a primary detection station, a secondary detection station, and a defective material discharging station along the rotating direction of the rotating disc 3. A primary visual detector 5 and a secondary visual detector 6 are respectively arranged on the primary detection station and the secondary detection station, and can be used for taking pictures of the products clamped by the clamps 4.

[0035] The primary visual detector 5 includes a first support 51, a primary detection camera 52 installed on the first support 51, and a first annular light source 53.

The other end of the first support 51 extends to the bottom of the support plate 1 and is connected with the primary detection camera 52. The detection end of the primary detection camera 52 is exposed on the support plate 1.

[0036] The primary detection camera 52 can take the first picture of the products clamped by the clamps 4, so as to ensure the stability and accuracy in the detection process and improve the reliability of the primary visual detection.

[0038] Specifically, the primary detection camera 52 and the secondary detection camera 62 are both composed of a CCD camera.

[0039] Specifically, when the rotating disc 3 rotates into the secondary detection station, the secondary detection camera 62 can take a second photo of the product held by the clamp 4, at this time, since the rotating disc 3 rotates by a certain angle, the secondary detection by the secondary detection camera 62 can further review and correct the results of the primary detection, ensure double insurance of detection, significantly improve the detection accuracy, thereby reducing the misjudgment phenomenon of the primary detection, and enhance the stability and reliability of the detection.

[0040] The reversing mechanism 7 comprises a connecting plate 71, a reversing seat 72 and a reversing motor 73, one end of the connecting plate 71 is connected with the lifting divider 2, the other end of the connecting plate 71 extends outward along the radial direction of the rotating disc 3 and is connected with the reversing motor 73, the reversing seat 72 is coaxially connected with the rotating shaft of the reversing motor 73, and a trough 74 for matching products is formed on the reversing seat 72.

[0041] When the primary detection camera 52 detects that the direction of the product is abnormal, such as the positive and negative directions of the polar capacitor do not match the set direction, the clamp 4 can be driven by the lifting divider 2 to hold the product and place it in the trough 74, the reversing seat 72 is driven by the reversing motor 73 to rotate to the set direction, thereby realizing the reversing operation of the product, improving the reversing efficiency of the product, ensuring the reliability of the product feeding, and enabling the product to be normally fed into the subsequent station for various test work.

[0042] The design of the trough 74 on the reversing seat 72 ensures the stability and accuracy of the product during the reversing process.

[0043] Specifically, the reversing seat 72 in the embodiment is a shaft coupling, the shaft coupling is coaxially connected with the rotating shaft of the reversing motor 73, and the trough 74 is opened at the top of the shaft coupling.

[0044] The clamp 4 is composed of a negative pressure suction nozzle, and a vacuum air source 12 is connected through a support frame 11. The design of the negative pressure suction nozzle can firmly adsorb the product, avoid falling or displacement during the material taking and detection process, and ensure the smooth progress of the entire detection process.

[0045] The negative pressure suction nozzle opens or closes the negative pressure suction force, so that the product can be sucked and released. At the same time, the negative pressure suction avoids surface indentation caused by mechanical clamping.

[0046] The incoming material station is provided with a material receiving seat 13, and the material receiving seat 13 is provided with a material receiving port for matching products. The defective material discharging station is provided with a defective material box 14 for collecting defective products.

[0047] The control of the lifting divider 2 ensures the stable placement and rapid transfer of the product during the detection process, and helps to improve the stability and reliability of the feeding.

[0048] The specific feeding action process in the embodiment is as follows:

[0049] The material receiving port of the material receiving seat 13 is communicated with the external vibration disc, so that the patch capacitor on the vibration disc enters the material receiving port. The rotation of the driving motor 10 drives the lifting divider 2 to rotate the negative pressure suction nozzle above the material receiving port, and the patch capacitor is sucked by the negative pressure suction force after being pressed by the lifting divider 2 to a preset height. The rotation of the turntable 3 makes the sucked patch capacitor enter the primary detection station, and the primary detection camera 52 can take the first photo of the product clamped by the clamp 4 for detection;

[0050] When the polarity direction of the patch capacitor is opposite to the set direction, the turntable 3 drives the patch capacitor to rotate above the reversing seat 72, and the patch capacitor is placed in the chute 74 under the driving of the lifting divider 2. The reversing motor 73 drives the reversing seat 72 to rotate and reverse, so that the polarity direction of the patch capacitor is consistent with the set direction, to ensure that the patch capacitor is conveyed to the subsequent test process in the preset direction, and continues to rotate into the secondary detection station. The secondary detection camera 62 can take the second photo of the product clamped by the clamp 4 for detection. The secondary detection can be used as a review and supplement of the primary detection result, to reduce the misjudgment rate caused by factors such as light change, lens pollution or product surface defects in single detection, to ensure the stability of the feeding and the smooth progress of the subsequent test link. After the secondary detection, the good product enters the next process, otherwise, the defective product enters the defective material discharging station under the rotation of the turntable 3 for discharging;

[0051] When the polarity direction of the patch capacitor is the same as the set direction, the turntable 3 drives the patch capacitor to directly enter the secondary detection station, and the secondary detection camera 62 can take the second photo of the product clamped by the clamp 4 for detection, which can reduce the reversing process and improve the stability and operation efficiency of the equipment.

[0052] In summary, by the incoming material work station, the first detection work station, the reversing work station, the second detection work station and the defective material discharging work station distributed in turn along the rotation direction of the rotary disc 3, an efficient and orderly work flow is formed, it is ensured that each step of the product from entering the feeding device to completing detection and classified processing can be controlled, the material processing time is reduced, meanwhile, the stability and reliability of the product detection can be improved, the accuracy of the product feeding into the next process is enhanced, and the production efficiency is improved.
