The cylindrical object is a cylindrical object, and has a structure similar to a shaft, and the object can be a single cylinder with the same diameter along the length direction of the object, or a plurality of cylinders with different diameters and coaxially arranged along the length direction of the object. The article can be a raw material, a primary processed product, a finished product, and the like.
The short rod detection device can detect whether the outer surface of the cylindrical detection object (such as the short rod 201) has surface flaws, wherein the flaws can be surface cracks, stains or whether the surface is smooth or not.
As shown in fig. 1 to 4, as an embodiment of the present stub bar detection apparatus, a surface configured as a stub bar 201 includes a mounting frame 101, at least two load-bearing columns 102, a first driver 103, at least one detection region 107, at least one detection head accommodation region 108, and at least one detection head 104. The details are as follows.
The bearing columns 102 are arranged in parallel and separated from each other 102, the distance between two adjacent bearing columns 102 is smaller than the maximum diameter of the short rod 201, when the bearing column 102 is in a rotating state, the short rod 201 is arranged between the two adjacent bearing columns 102 and is arranged in parallel with the axial direction of the bearing column 102.
The first driver 103 is directly or indirectly connected with the carrying columns 102, and drives the carrying columns 102 to rotate around the axes thereof in the same rotating direction and the short rods 201 carried on two adjacent carrying columns 102 to rotate in the opposite rotating direction to the carrying columns 102 in use.
It should be noted that the first driver 103 here usually adopts a motor as a driver to realize the rotation motion, and in order to better control the rotation speed of the carrying column 102, a speed reducer is installed between the first driver 103 and the carrying column 102, although the motor can also be a variable frequency motor with variable frequency control capability. In addition, in order to make the short rods 201 on the pair of carrying columns 102 operate more smoothly, the pair of carrying columns 102 can be rotated synchronously in the same direction by a transmission mechanism, such as one or more combinations of gears, sprockets and chains, pulleys and conveyor belts.
The detection region 107 is a spacing portion provided between two adjacent ones of the support pillars 102.
It should be noted that the detection region 107 is used to observe a portion of the short rod 201 carried on the carrying column 102, and since the short rod 201 is in rotation, all different outer surfaces of the short rod 201 in the radial direction can be observed through the detection region 107.
The detection head accommodation regions 108 are provided below the detection regions 107 corresponding to the detection heads one by one.
The detection heads 104 are disposed in the detection head accommodating regions 108, and correspond to the detection head accommodating regions 108 one to one. The detection head 104 is used for acquiring image information of the outer surface of the short rod 201, and may generally comprise a camera.
The bearing columns 102 and the first driver 103 are disposed on the mounting frame 101, and the detection head 104 is used for acquiring image information of the circumferential outer surface in the radial direction on the rotating cylindrical short rod 201 borne on two adjacent bearing columns 102 in use.
The working principle is as follows: under the driving of the first driver 103, the pair of carrying columns 102 rotate in the same direction, so as to drive the short rod 201 carried on the pair of carrying columns 102 to rotate independently in a rotation direction different from that of the carrying columns 102, a single detection head 104 located in one detection head accommodating area 108 acquires image information of the outer surface of the short rod 201 in the radial direction in rotation through the detection area 107 corresponding to the single detection head, and after the short rod 201 in rotation rotates for one circle, the detection head 104 can acquire image information of the entire circumferential outer surface of the short rod 201 in the radial direction. The image information can be used to determine whether the surface of the stub 201 has defects, so as to determine whether the stub 201 is qualified.
As an embodiment of the detection device, it further includes a detection head driving assembly, which is disposed on the mounting frame 101 at a position corresponding to the lower portion of the detection area 107, and the free end of the detection head driving assembly is connected to the detection head 104, and drives the detection head 104 to reciprocate along the axial direction of the bearing column 102 in the detection head accommodating area 108 during use.
It should be noted that, since the detection head 104 is limited by its performance, its view field and generated image resolution are different, and in order to make the detection head 104 with poor performance available, a detection head driving assembly is provided, so that the detection head 104 can reciprocate along the axial direction of the short rod 201 through the detection head driving assembly to have a better and clearer image information on the circumferential outer surface of the short rod 201 in the radial direction. There are various structures of the driving assembly of the detection head.

In addition, in order to improve the smoothness of the detection head 104 during movement, the detection head driving assembly further includes a first sliding assembly and a first slider 115. The first sliding component includes a first sliding rail 114 or a first sliding groove, which is disposed at a position on the mounting frame 101 below the detection area 107 and is disposed along an axial direction of the bearing column 102. When the first sliding block 115 is used, the first sliding rail 114 or the first sliding groove is in sliding fit with the first sliding block 115 connected to the detection head 104, and the first sliding block 115 is directly or indirectly connected with the free end of the linear driver 113. In this way, the detection head 104 is driven by the linear driver 113 to reciprocate along the length direction of the fixed first sliding assembly, and the phenomenon of deviation does not occur, so as to facilitate the acquisition of the image information of the short rod 201 by the detection head 104.
As another embodiment of the detection head driving assembly, as shown in fig. 2, 3 and 4, it includes a rotary disk 109, a second driver 110, a link 111 and a second sliding assembly. The second driver 110 is in rotational engagement with the rotary disc 109. One end of the connecting rod 111 is hinged to a non-axial part of the rotating disc 109, and the other end is connected with the detection head 104. The second sliding assembly includes a second sliding rail 106 or a second sliding groove, and a second sliding block 105. The second slide rail 106 or the second slide groove is disposed at a position below the detection area 107 on the mounting frame 101, and is disposed along an axial direction of the bearing column 102. The second slide block 105, when in use, the second slide rail 106 or the second slide groove is in sliding fit with the second slide block 105 connected to the detection head 104, and the second slide block 105 is hinged with the other end of the connecting rod 111. The reciprocating movement of the detection head 104 is realized here by an eccentric structure and a connecting rod 111, wherein the rotating disc 109 can also be an eccentric wheel as a preference.
It should be noted that the second driver 110 herein usually adopts a motor as a driver to implement a rotating motion, and in order to better control the rotating speed of one end of the connecting rod 111 connected thereto, a speed reducer is installed between the second driver 110 and the connecting rod 111, although the motor may also be an inverter motor with an inverter control capability, and in addition, the shape of the connecting rod 111 is not limited, such as a straight line shape or a bent shape, and the like, and may be specifically set according to actual situations. In addition, in order to effectively control the operation speed of the connecting rod 111, the control of the movement speed of the connecting rod 111 can be realized by a transmission mechanism, such as one or more combinations of gears, chain wheels and chains, belt wheels and conveying belts.
As an embodiment of the short rod detecting apparatus, it further includes a data processing unit 112, and the data processing unit 112 identifies whether there is a crack in the circumferential outer surface in the radial direction on the short rod 201, based on the image information acquired by the detecting head 104. The data processing unit 112 may be a microprocessor chip. Which may use image algorithms to identify whether image information from the detection head 104 is flawed.
As an embodiment of the short rod detection device, in order to facilitate the observation of the short rod 201 by the detection head 104, the length of the detection region 107 along the axial direction of the bearing column 102 is greater than or equal to the length of the short rod 201.
In addition, in order to better control the rotation of the short rod 201, as an embodiment of the detection device, when the short rod 201 is carried on two adjacent carrying columns 102, an included angle formed by a first perpendicular to a first axis on the workpiece and a second axis on one carrying column 102 and a second perpendicular to the second axis on two adjacent carrying columns 102 is in a range of 25 degrees to 75 degrees. When the included angle is smaller than 25 degrees, the pressure of the support columns 102 on the short rod 201 is small, which is not beneficial to driving the short rod 201 to rotate, and when the included angle is larger than 75 degrees, the short rod 201 is easy to separate from the two support columns 102.
As an embodiment of the short rod detection device, the distance between the axes of two adjacent load-bearing columns 102 is larger than the diameter of the short rod 201. This facilitates the short rod 201 to be located between the two bearing columns 102 during rotation, and facilitates the short rod 201 to operate stably so as to facilitate the detection of the detection head 104.
