Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in figure 1, the device for comprehensively detecting the defects of the bearing parts based on image recognition comprises a feeding end 1 and a discharging end 2.

As shown in fig. 1, 2 and 3, a mounting frame 3 is arranged between the feeding end 1 and the discharging end 2. Wherein, feed end 1 and discharge end 2 are prior art's conveyor, and it is used for waiting to detect the bearing and send into mounting bracket 3 to the bearing that will accomplish the detection shifts out from mounting bracket 3. As an example, the feeding end 1 and the discharging end 2 may be conveyor belts, and the specific structure thereof is not described in detail in this embodiment. More specifically, the mounting frame 3 is rotatably connected with a roller 4. Meanwhile, a driving piece 6 capable of driving the roller 4 to rotate is further arranged on the mounting frame 3. Preferably, the drive member 6 is an electric motor. In addition, the detection device further includes a detection camera 20, and the installation position and the detection mode of the detection camera 20 are the same as those of the prior art, so detailed description is not given in this embodiment.

Further, the roller 4 comprises two opposite mounting plates 17, a driving plate 18 is arranged between the two mounting plates 17 in an enclosing manner, and a mounting cavity 7 is formed between the two mounting plates 17 and the driving plate 18. In order to directly move the defective bearing detected by the detection camera out of the production line, two through grooves 19 are arranged on the driving plate 18 in a penetrating manner, the driving device 8 is arranged in the mounting cavity 7, and the driving device 8 is provided with two telescopic output ends. Wherein, one output end of the driving device 8 is connected with a concave plate 9, and the other output end is connected with a convex plate 10. The concave plate 9 and the convex plate 10 can be respectively clamped into the two through grooves 19 under the ejection action of the driving device 8 and are jointed with the outer surface of the driving plate 18. It will be appreciated that the recess of the recess plate 9 will now form the feed chute 5 of the prior art roller 4. Meanwhile, the driving device 8 is electrically connected to the inspection camera 20.

For ease of understanding, the following will describe how the inspection device performs different actions on qualified and unqualified bearings. That is to say that the first and second electrodes,

when the bearing detected by the detection camera is a qualified product, the driving device 8 does not respond, and the bearing can be driven by the feeding groove 5 formed by the concave plate 9 to rotate to the discharge end 2; when the bearing that detection camera detected is unqualified product, detection camera will convey the signal of telecommunication to drive arrangement 8, and drive arrangement 8 will be subsequently retrieved two output after the bearing gets into chute 5. At this point the bearing will fall into the mounting cavity 7 and fall under the force of gravity from the open through slot 19 of the drive plate 18 as the lug 10 is retracted.

Further, the two through slots 19 are disposed opposite to each other, and the driving device 8 includes a back-to-back cylinder. Wherein, two output shafts of the back-to-back cylinder are respectively opposite to the two through grooves 19, and the convex plate 10 and the concave plate 9 are respectively arranged on the two output shafts of the back-to-back cylinder. It should be noted that, the back-to-back cylinder is an integrated device of double cylinders, which is the prior art. In addition, the groove of the concave plate 9 can be arranged obliquely, so that the bearing can roll off from the concave plate 9 when the driving device 8 retracts the concave plate 9 more easily, and the situation that the bearing is clamped between the feeding groove 5 and the driving plate 18 is not easy to occur.

A coupling hole 16 is formed through the center of the sidewall of the mounting plate 17, and the coupling hole 16 is used to mount a rotary joint (not shown). The trachea of back-to-back cylinder can be connected on the rotary joint, so when back-to-back cylinder rotated along with gyro wheel 4 together, the difficult condition that appears knoing of trachea. The rotary joint is also the prior art, and is not described in detail in this embodiment.

And in order to realize that the defective bearing that drops is difficult for appearing the condition of secondary damage, mounting bracket 3 is located and is provided with material receiving box 11 in the below of gyro wheel 4, and material receiving box 11 can accept, accomodate the bearing that drops.

Furthermore, a material baffle plate 12 is hinged to the inner wall of the material receiving box 11, a spring 13 is connected between the material baffle plate 12 and the material receiving box 11, and the spring 13 is used for pushing the material baffle plate 12 away from the inner wall of the material receiving box 11 and maintaining the elastic force of the material baffle plate 12 inclining to one side of the bottom of the material receiving box 11. Furthermore, the fallen defective bearing will impact the striker plate 12, during which the spring 13 deforms to absorb the impact force, so that the defective bearing falls into the material receiving box 11 more softly.

The bottom surface of the receiving box 11 is designed as an inclined surface 14, and the inclined surface 14 is inclined toward the striker plate 12. Further, the inclined surface 14 can again apply a force to the impact force of the defective bearing.

Preferably, the striker plate 12 and the inclined surface 14 are both provided with an elastic part 15, and the elastic part 15 comprises rubber. The rubber has better deformation and force-unloading performance, so that the defective bearing is not easy to damage due to impact.
