Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, and merely illustrates the basic structure of the present invention in a schematic manner, and therefore it shows only the constitution related to the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The dental drill thread measuring device comprises a vibrating screen 1 and a detecting mechanism 2 arranged on one side of the vibrating screen 1. When the dental drills need to be detected, the dental drills are firstly placed into the vibrating screen 1, so that the dental drills are orderly arranged under the action of the vibrating screen 1 and are discharged to the detecting mechanism 2.

Specifically, referring to fig. 1, the vibrating screen 1 includes a first PLC controller, a screen box 11, a feeding port 111, a discharging port 112, a screen surface 12 disposed in the screen box 11, a vibrating screen motor 13 disposed on one side of the screen box 11, and a vibrator 14 disposed on the screen box 11. When needing to measure the tooth and bore the screw thread, place the work piece at first into the feed inlet 111 of shale shaker 1, shale shaker motor 13 starts, make 14 of vibrator begin to operate, it makes sifter 12 produce the vibration of circling round in the plane to go up the rotary weight, and lower rotary weight makes the sifter produce conical surface rotary vibration, the effect of its combined action makes sifter 12 produce the vibration of the type of revolving again, make the tooth that bores at feed inlet 111 reach sifter 12 under the effect of shale shaker 1, and reach the discharge gate 112 of shale shaker 1 through sifter 12. The discharge port 112 of the vibrating screen 1 is flat and oval, and is provided with a discharge switch, so that the dental drill reaching the discharge port 112 waits for a blanking signal of the first PLC at the discharge port 112 and blanks once every 1-2 seconds, and the dental drill enters the detection mechanism 2.

Specifically, as shown in fig. 1, the detection mechanism 2 includes a second PLC controller, an index plate 21, an index plate motor 211 disposed at a lower end of the index plate 21, a feeding mechanism 22 disposed on the index plate 21 in sequence in a counterclockwise direction, a visual detection system 23, a non-defective product blanking area 24, and a non-defective product blanking area 25. The feeding mechanism 22 comprises a negative pressure suction nozzle 221 and a negative pressure cavity 222 arranged below the negative pressure suction nozzle 221, when the dental drill reaches the feeding mechanism 22 through the discharge hole 112 of the vibrating screen 1, air is continuously pumped away through the negative pressure cavity 222, so that negative pressure is generated near the negative pressure suction nozzle 221, and the dental drill falling on the feeding mechanism 22 is adsorbed on the dividing disc 21. At the same time, the index plate motor 211 starts to drive the index plate 21 to rotate. The indexing disc 21 rotates once counterclockwise to drive the dental drill adsorbed on the feeding mechanism 22 to the visual inspection system 23.

The visual inspection system 23 includes a light source 231 provided at the lower end of the index plate 21, and a camera 231 provided directly above the index plate 21 and the light source 231. The index plate 21 is made of a high-transmittance glass material, so that the light source 231 arranged below the index plate 21 can irradiate the dental drills adsorbed on the feeding mechanism 22 through the index plate 21. The camera 232 is an industrial camera with a telecentric lens, and under the irradiation of the light source 231, the camera 232 can successfully acquire a gray scale image of the dental bur. After the camera 232 collects the grayscale images, the image data are transmitted to the second PLC, the collected dental drill images are judged through the second PLC, and the dental drill is determined to be a qualified product or an unqualified product. The judgment method refers to CN 111665251A-a surface defect visual inspection method, firstly, a reference value is set, the average value of the gray value in each standard area is extracted and calculated in sequence, and each standard area is judged to be a background noise area or an abnormal area; averaging the differences of a plurality of standard areas in the background noise area to obtain an environmental noise difference; and comparing the gray value of each pixel in the detected product image minus the environmental noise difference value with a threshold value, and judging whether the pixel point is a defect point.

When the dental drill is judged to be qualified, the indexing disc 21 drives the feeding mechanism 22 to rotate anticlockwise for one time, so that the dental drill reaches the qualified product blanking area 24, and the negative pressure is weakened at the moment, so that the dental drill can be blanked smoothly. When the dental drill is judged to be an unqualified product, the indexing disc 21 rotates once in the anticlockwise direction after reaching the qualified product blanking area 24, so that the feeding mechanism 22 reaches the unqualified product blanking area 24, and the negative pressure is weakened at the moment, so that the dental drill can be blanked smoothly.

Optionally, the blanking mode may use an electromagnetic mode to grab the dental drill.

When the dental drill thread measuring device is in operation, the dental drill is first placed in the feed port 111 of the vibrating screen 1, and the vibrating screen motor 13 is started, so that the vibrator 14 starts to operate, and the dental drill enters the screen surface 12 and reaches the discharge port 112 of the vibrating screen 1 through the screen surface 12. And a discharge switch is arranged at the discharge port 112 and is controlled by a first PLC controller. The dental drill waits for a blanking signal of the first PLC at the discharge port 112, blanking is performed once every 1-2 seconds, and the discharge switch is turned on, so that the dental drill enters the detection mechanism 2. The dental drill is sucked to the feeding mechanism 22 by the negative pressure suction nozzle 221 of the feeding mechanism 22. The index plate motor 211 is activated to rotate the index plate 21 once in a counterclockwise direction to the vision inspection system 23. Under the action of the light source 231, the camera 232 acquires a gray scale image of the dental drill and transmits image data to the second PLC, so that the second PLC judges the image and controls the blanking of the dental drill through the judgment. If the result of the dental drill is qualified, the index plate 21 rotates once in the counterclockwise direction to reach the qualified product blanking area 24, and the negative pressure of the feeding mechanism 22 is weakened at the moment, so that the dental drill can be blanked smoothly. If the dental drill determination result is an unqualified product, the dividing plate 21 rotates once in the counterclockwise direction after reaching the qualified product blanking area, so that the feeding mechanism 22 reaches the unqualified product blanking area 25 under the driving of the dividing plate 21, and at the moment, the negative pressure of the feeding mechanism 22 is weakened, so that the dental drill can be blanked smoothly.

Through the cooperation of each part in this dental drill screw thread measuring device for dental drill testing process can realize automaticly, can reduce the human cost and reduce the defective work that brings because of the manpower detects the problem of examining neglected checking through vision detecting system 23 simultaneously.

In the several embodiments provided in the present application, it should be understood that the disclosed system, apparatus and method may be implemented in other ways. The above-described embodiments of the apparatus are merely illustrative, and for example, the division of the units is only one logical division, and there may be other divisions when actually implemented, and for example, a plurality of units or components may be combined or integrated into another system, or some features may be omitted, or not executed.
