Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 3, a visual sorting apparatus for minute products may include a vibratory loading tray 1, two industrial cameras 2, and two sorting assemblies 3. The vibrating feeding tray 1 is provided with two discharging channels 11, and the vibrating feeding tray 1 has the function of orderly arranging and outputting unordered products. At present, the vibration feeding tray is widely applied to various industries such as batteries, hardware, electronics, food and the like, and the structure of the vibration feeding tray is well known and is not described here. Each sorting assembly 3 can comprise a rotary disc 31, a servo motor 32, an OK blowing nozzle 33 and an NG blowing nozzle 34, a plurality of product contour grooves 311 are machined on the rotary disc 31, the number of the product contour grooves 311 can be divided into 8, 16, 32 and the like according to the size of the product, and each contour groove 311 can bear a single product. The turntable 31 is driven by a servo motor 32 to rotate in equal circumferential intervals according to the number of slots. The precision of the servo motor can reach 0.0001 degree at present. The turntable 31 is provided with a feeding station 31A, a visual inspection station 31B, NG discharging station 31C and an OK discharging station 31D in this order in the rotational direction. The two discharging channels 11 are respectively communicated with the profiling grooves 311 on the feeding stations 31A of the two turntables 31. That is, the products are orderly arranged and discharged out of the contour grooves 311 of the turntable 31 by vibrating the loading tray 31. The industrial camera 2 is disposed right above the visual inspection station 31B, and is configured to photograph the product on the contour groove 311 and determine whether the product is oriented correctly. The OK blowing nozzle 33 and the NG blowing nozzle 34 are arranged on the OK discharging station 31D and the NG discharging station 31C, respectively. When the industrial camera 2 detects that the product direction is incorrect (i.e., NG), the NG blowing nozzle 34 is actuated to blow the product down onto the NG product collection bin 4 therebelow, and the product with the correct direction (i.e., OK) is blown by the OK blowing nozzle 33 onto the OK output channel 51 communicating with the contour groove 311 at the OK discharging station 31D.

In the illustrated embodiment, the outlet sections of the two OK output channels 51 are immediately adjacent to facilitate downstream operations. In the illustrated embodiment, two OK output channels 51 are provided on a straight vibrating conveyor 5 to move the product downstream along the OK output channels 51. Of course, the two OK output channels 51 may be provided on the conveyor belt

Preferably, the feeding station 31A, OK and the discharging station 31D and the NG discharging station 31C are respectively provided with a detection sensor 6 for detecting whether a product is on the corresponding station. Through setting up detection sensor 6, can avoid the malfunction, ensure that whole sorting unit is high-efficient to operate smoothly.

In addition, the visual sorting device for the tiny products can also comprise a limiting plate 7, wherein the limiting plate 7 is flat at the OK discharging station 31D, so that the OK products are prevented from turning over when being blown onto the discharging channel 51 by an OK blowing nozzle; and is upturned at the NG discharging station 31C, so that the NG product can be smoothly blown down into the NG product collecting box.

In order to ensure the video image to be clear, the visual sorting device for the tiny products can also comprise a light source 8, and the light source 8 is arranged above the visual detection station 31B in an angle-adjustable mode.

The working principle of the utility model is briefly explained below, the vibration is gone up charging tray 1 and is carried out unordered product material loading sequencing, and then the product gets into carousel 31 with arbitrary direction, and carousel 31 drives the product and does the angular rotation such as wait, and the rotation all stops 0.1s at every turn and supplies industrial camera 2 to shoot and handle. The method aims to ensure that the product is in a static state during each detection, so that the detection precision of the product can be improved. Products after the visual detection of the industrial camera 2 are correspondingly processed according to the visual detection result, NG products can be removed by blowing, and OK products can enter the next work station. The utility model has the advantages that can solve the direction screening of arbitrary small product, and the carousel carries out visual detection again for the product and provides the platform that a static was shot, realizes the direction screening of small product 100% exactness basically.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
