For example, the projection of the connecting block 15 in the horizontal plane is a regular triangle structure.

[0053] Further, in order to facilitate conveying, the conveying belt 124 is a round belt, that is, the cross section of the conveying belt 124 is a circular structure.

[0054] Furthermore, a first transition block 16 is provided on the first mounting plate 112 on the inner side of the driven pulley 123 (with the side closer to the crossbeam 111 as the inner side).

A limiting groove for accommodating the conveyor belt 124 is provided on the outer side of the guide plate 18. By setting the first transition block 16, the second transition block 17 and the guide plate 18, and providing the limiting groove for accommodating the conveyor belt 124 on the first transition block 16, the second transition block 17 and the guide plate 18, the conveyor belt 124 can be prevented from sagging due to its own weight, thereby ensuring that the conveyor belt 124 is always in contact with the head 42 of the valve 4, and the valve 4 remains vertical during the conveying process, avoiding skewing.

[0055] A first track 21 is provided on one side of the conveying component 1 (according to...) Figure 1 In the coordinate system shown, the first track 21 is located in front of the conveying component 1. A first conveying channel 31 for conveying the valve 4 is formed between the first track 21 and the conveying component 1. During conveying, the stem 41 of the valve 4 is inserted into the first conveying channel 31, one side of the head 42 of the valve 4 overlaps the conveyor belt 124, and the other side of the head 42 of the valve 4 overlaps the first track 21. When the conveyor belt 124 moves, it can drive the valve 4 to rotate and move forward at the same time.

[0056] The first conveying channel 31 is provided with a material separating mechanism 5, a clamping mechanism 6 and a material dividing mechanism 7 arranged sequentially along the conveying direction. An industrial camera 82 is arranged directly above the clamping mechanism 6.

[0057] The material blocking mechanism 5 is used to block the air valve 4, so that the air valve 4 can pass through the clamping mechanism 6 one by one. The clamping mechanism 6 is used to clamp and fix the air valve 4, so as to facilitate the shooting of the industrial camera 82, ensure that the industrial camera 82 can pick up a clear image, improve the accuracy of sorting judgment, and the industrial camera feeds back the image to the control unit (not shown in the figure), and the control unit compares the image fed back by the industrial camera with the pre-stored image information, so as to sort out the air valve 4 that does not meet the requirements. The material distribution mechanism 7 is distributed according to the comparison result of the control unit, so as to sort out the air valve 4 that does not meet the quality requirements, and the air valve 4 that meets the quality requirements enters the next process.

[0058] As shown in Figure 1 and Figure 9 , the material blocking mechanism 5 includes a first material blocking cylinder 51 and a second material blocking cylinder 52, the first material blocking cylinder 51 is located on the upstream side of the second material blocking cylinder 52, and the first material blocking cylinder 51 and the second material blocking cylinder 52 are respectively fixedly connected with the first track 21 through a first support 53. The rod end of the piston rod of the first material blocking cylinder 51 is fixedly provided with a first material blocking block 511 in a detachable manner, and the rod end of the piston rod of the second material blocking cylinder 52 is fixedly provided with a second material blocking block 521 in a detachable manner. The first track 21 is provided with a first avoiding hole 211, when the first material blocking cylinder 51 and the second material blocking cylinder 52 act, the first material blocking block 511 and the second material blocking block 521 can move to the inside of the first track 21, that is, extend into the first conveying channel 31, so as to prevent the movement of the air valve 4. The distance M between the first material blocking block 511 and the second material blocking block 521 is greater than the diameter of the rod part 41 of the air valve 4.

[0059] The working process of the material blocking mechanism 5 is as follows:

[0060] First, as shown in Figure 14 , the piston rod of the first material blocking cylinder 51 is extended, and at this time the air valve 4 located at the leftmost side is limited on the upstream side of the first material blocking block 511. Then, as shown in Figure 15 , the piston rod of the second material blocking cylinder 52 is extended, and at the same time the piston rod of the first material blocking cylinder 51 is retracted, at this time the air valve 4 will move to the downstream side under the driving action of the conveying part 1, until the air valve 4 located at the leftmost side abuts against the second material blocking block 521. Then, as shown in Figure 16 , the piston rod of the first material blocking cylinder 51 is extended again, and the first material block is inserted between the two air valves 4 located at the leftmost side. Then, as shown in Figure 17As shown, the piston rod of the second material separation cylinder 52 is retracted, at this time, the valve 4 located between the first material separation block 511 and the second material separation block 521 is no longer restricted, and can continue to move to the downstream side under the driving of the conveying component 1, and the remaining valves 4 will also move to the downstream side with the conveying component 1 for a distance, until the leftmost valve 4 among the remaining valves 4 abuts against the first material separation block 511.

[0061] Further, as shown in the drawings, Figure 9 As shown, a partition plate 54 is arranged between the first material separation cylinder 51 and the second material separation cylinder 52, and the cylinder bodies of the first material separation cylinder 51 and the second material separation cylinder 52 are fixedly connected to the partition plate 54 in a detachable manner. When the first material separation cylinder 51 and the second material separation cylinder 52 are in the extended state, the end of the partition plate 54 towards the conveying component 1 is clamped between the first material separation block 511 and the second material separation block 521, and the end face of the partition plate 54 towards the conveying component 1 is located outside the inner side of the first track 21 (the side towards the conveying component 1 is the inner side). By arranging the partition plate 54, the rotation of the first material separation block 511 and the second material separation block 521 during extension or retraction can be avoided.

[0062] As shown in the drawings, Figure 1 , Figure 9 and Figure 18 As shown, the clamping mechanism 6 includes a clamping jaw cylinder 61, the cylinder body of the clamping jaw cylinder 61 is fixedly connected to the first track 21 through a second support 62, and the first track 21 is provided with a second avoiding hole 212 for avoiding the clamping jaw 611 of the clamping jaw cylinder 61. When the clamping jaw cylinder 61 is in the open state, the clamping jaw 611 of the clamping jaw cylinder 61 is horizontally opened and located outside the first conveying channel 31, and does not affect the conveying of the valve 4. When the valve 4 to be detected moves to the clamping jaw cylinder 61, the clamping jaw cylinder 61 acts to clamp the stem portion 41 of the valve 4 to be detected.

[0063] As a specific embodiment, the lower side of the first track 21 or the cross beam 111 is provided with a photoelectric switch (not shown in the drawings), when the valve 4 moves to the clamping jaw cylinder 61, the stem portion 41 of the valve 4 is aligned with the photoelectric switch, after the photoelectric switch detects the valve 4, the photoelectric switch sends a signal to the control unit, and the control unit controls the clamping jaw cylinder 61 to act according to the signal fed back by the photoelectric switch, so as to clamp the stem portion 41 of the valve 4 to be detected.

[0064] As shown in the drawings, Figure 2As shown, the material distribution mechanism 7 includes a material distribution plate 71 and a material distribution cylinder 72 for moving the material distribution plate 71 closer to or away from the conveying component 1. The first track 21 is provided with a material distribution notch 213 for accommodating the material distribution plate 71. The material distribution plate 71 has a right-angled triangular structure, with one right-angled side facing the conveying component 1, the other right-angled side facing the downstream side, and the hypotenuse facing the upstream side.

[0065] The material distribution plate 71 has two working positions: when the material distribution plate 71 is in such a position as Figure 6 In the first working position shown, the material distribution plate 71 is close to the conveying component 1, and the first conveying channel 31 is cut off and blocked by the material distribution plate 71. The valve 4 conveyed from upstream will be moved out from the material distribution notch 213 under the guidance of the inclined side of the material distribution plate 71. When the material distribution plate 71 is in the position shown... Figure 7 In the second working position shown, the right-angled side of the material distribution plate 71 facing the conveying component 1 is flush with the inner side of the first guide rail (with the side facing the conveying component 1 as the inner side), and the upper side of the material distribution plate 71 is flush with the upper side of the first guide rail. At this time, the valve 4 located on the upstream side of the material distribution plate 71 can move to the downstream side of the material distribution plate 71 through the material distribution plate 71, and the first conveying channel 31 is in the conducting state.

[0066] As one specific implementation method, such as Figure 2 and Figure 3 As shown, in this embodiment, a third support 73 is provided on the crossbeam 111 of the conveying component 1. The cylinder body of the distributing cylinder 72 is detachably fixedly connected to the third support 73, and the piston rod end of the distributing cylinder 72 is detachably provided with a connecting frame 74. A vertical rod 75 is provided on the distributing plate 71, and the lower end of the vertical rod 75 is detachably fixedly connected to the distributing plate 71. A connecting column 76 is provided on the vertical rod 75 above the distributing plate 71, and the connecting column 76 is fixedly connected to the connecting frame 74 by a locking bolt 77.

[0067] Further, the connecting column 76 is arranged perpendicularly to the vertical rod 75, and a through hole for accommodating the vertical rod 75 is arranged on the connecting column 76. A threaded hole matched with the locking bolt 77 is coaxially arranged on the connecting column 76 and communicates with the through hole. An elastic compression sleeve 78 is sleeved on the connecting column 76 between the vertical rod 75 and the connecting frame 74. In this way, when the locking bolt 77 is tightened, the connecting column 76 and the connecting frame 74 are connected and fixed, and the vertical rod 75 is clamped by the locking bolt 77, so that the vertical rod 75 and the connecting column 76 are connected and fixed. Only one bolt needs to be tightened to achieve the connection and fixation of two positions, which is convenient to operate.

[0068] Further, the mounting hole 741 for accommodating the locking bolt 77 on the connecting frame 74 is an oblong hole extending in the front-rear direction.

[0069] As shown in Figure 1 The industrial camera 82 is fixedly connected with the cross beam 111 through the fourth support 81.

[0070] As shown in Figure 10 The fourth support 81 includes a base 811 and a stand 812 arranged on the base 811.

The lower end of the stand 812 is inserted into the mounting jack and is fixedly connected with the base 811 through a locking screw (not shown in the figure). The stand 812 is provided with a first cross rod 813 arranged perpendicularly to the stand 812, and one end of the first cross rod 813 is fixedly connected with the stand 812 through a first clamping block 814. The first cross rod 813 is provided with a second clamping block 8131, and the second clamping block 8131 is provided with a third mounting plate 8132. The industrial camera 82 is fixedly installed on the third mounting plate 8132 through screws.

[0071] During installation, the angle of the first cross rod 813 in the horizontal plane can be adjusted, and the position of the second clamping block 8131 on the first cross rod 813 can be adjusted at the same time, so that the industrial camera 82 is located directly above the clamping mechanism 6. In this way, after the clamping mechanism 6 clamps the valve 4 to be detected, it can be ensured that the valve 4 to be detected is within the field of view of the industrial camera 82.

[0072] Further, as shown in Figure 10As shown, a second horizontal bar 815 is arranged perpendicularly to the column 812, located below the first horizontal bar 813. One end of the second horizontal bar 815 is fixedly connected to the column 812 via a third clamping block 816. Two fourth clamping blocks 8151 are provided on the second horizontal bar 815, each of which has a mounting rod 8152 extending to the same side. A light source 83 is positioned between the two mounting rods 8152, and both ends of the light source 83 are detachably fixedly connected to the mounting rods 8152.

[0073] In one specific implementation, the light source 83 in this embodiment is a ring light source 83, and it is located directly below the industrial camera 82. The industrial camera 82 can take pictures of the valve 4 to be inspected through the inner hole area of ​​the ring light source 83.
