[0001] The utility model relates to the field of glass bottle manufacturing, and particularly relates to an auxiliary device for detecting the inner diameter of the neck part of a controlled bottle. Background Art

[0002] When detecting the inner diameter of the neck of a controlled bottle by a controlled bottle manufacturing machine, the controlled bottle needs to be placed on a conveying mechanism. The two sides of the controlled bottle are tangent to the conveying mechanism. A light source irradiates the controlled bottle from one side, and a camera takes a picture of the neck from the other side to detect the inner diameter size. Due to bumps or wear after long-term use, etc., the conveying mechanism will be deformed, etc., resulting in the camera not being parallel to the neck, causing errors in detecting the inner diameter. As a result, qualified products are judged as unqualified products, affecting the qualification rate of the equipment. Since the conveying mechanism is used for positioning the controlled bottle, when deformation occurs, etc., the conveying mechanism needs to be replaced, with high replacement cost and high labor intensity.

[0024] The following further describes the present utility model in conjunction with Figure 1 , Figure 2 , Figure 3 , Figure 4 .

[0025] An auxiliary device for detecting the inner diameter of the bottleneck of a controlled bottle, comprising a conveying line 1 for conveying the controlled bottle, a camera 2 arranged on one side of the conveying line 1, and a light source 3 arranged on the other side of the conveying line 1 opposite to the camera 2, further comprising: a connecting plate II 10, which is installed on the frame of the conveying line 1 through a height adjusting mechanism, and the height adjusting mechanism drives the connecting plate II 10 to move up and down; a connecting plate I 9, arranged at the upper end of the connecting plate II 10, and the connecting plate I 9 slides up and down relative to the connecting plate II 10 through a guiding mechanism; a driving mechanism, arranged on the height adjusting mechanism, for driving the connecting plate I 9 to move up and down under the guidance of the guiding mechanism; a positioning block 21, installed at the lower end of the connecting plate II 10, and an inverted V-shaped positioning groove 22 is arranged along the length direction of the positioning block 21, and the positioning groove 22 is parallel to the optical axis of the camera 2; and a straw mechanism, arranged on the connecting plate I 9, for sucking the controlled bottle on the conveying line 1. When the connecting plate I 9 moves up, the sucked controlled bottle is clamped in the positioning groove 22. During use, after the conveying line 1 conveys the controlled bottle below the connecting plate II 10, the driving mechanism drives the connecting plate I 9 to move down under the guidance of the guiding mechanism. After the straw mechanism moves down, it sucks the controlled bottle on the conveying line 1. Then the driving mechanism drives the connecting plate I 9 to move up under the guidance of the guiding mechanism. The controlled bottle in the sucking state moves up to the positioning groove 22 of the positioning hole 21. Since the positioning groove 22 is parallel to the optical axis of the camera 2, the controlled bottle rotates to be parallel to the optical axis of the camera 2 after being positioned by the positioning groove 22. The light emitted by the light source passes through the controlled bottle and is photographed by the camera 2, so as to facilitate the industrial vision system to detect the inner diameter size of the controlled bottle. The detection error is greatly reduced, the qualified products of the controlled bottle are prevented from being misjudged as unqualified products, the qualified rate is improved, the consumption cost of consumables is reduced, and the labor intensity is reduced. The height position of the connecting plate II 10 relative to the conveying line 1 can be adjusted through the height adjusting mechanism, so as to be applicable to controlled bottles with different outer diameter specifications.

[0026] In an embodiment of the present utility model, the height adjustment mechanism includes a bracket 6, a linear guide rail 5 and a screw rod 7 screwed onto the bracket 6, which are installed on the frame of the conveyor line 1. The linear guide rail 5 is arranged vertically, and a slider 4 slidably installed on the linear guide rail 5 is fixed to the bracket 6. A connecting plate Ⅰ 9 is fixedly connected to the lower end of the linear guide rail 5. The axis of the screw rod 7 is arranged vertically. A screw hole matching the screw rod 7 is arranged vertically at the upper end of the linear guide rail 5, and the lower end of the screw rod 7 is screwed into the screw hole at the upper end of the linear guide rail 5. By rotating the screw rod 7, the linear guide rail 5 can be driven to move up and down, thereby driving the connecting plate Ⅱ 10 to move up and down, adjusting the height of the entire inspection auxiliary device for the inner diameter of the bottleneck of the control bottle, and facilitating the adaptation to control bottles of different specifications. In this embodiment, preferably, a nut 8 is also screwed onto the screw rod 7. After the height of the connecting plate Ⅱ 10 is adjusted in place, locking the nut 8 can lock and fix the screw rod 7, preventing the rotation of the screw rod 7 from causing a change in the height position of the connecting plate Ⅱ 10, and further improving the reliability of use.

[0027] In an embodiment of the present utility model, the guiding mechanism includes a guide rod 24 installed vertically on the connecting plate Ⅱ 10 and a linear bearing 15 installed on the connecting plate Ⅰ 9. The axis of the guide rod 24 is arranged vertically, and the guide rod 24 is inserted into the linear bearing 15. When the driving mechanism drives the connecting plate Ⅰ 9 to move up and down, it moves up and down under the guidance of the guide rod 24 through the linear bearing 15, improving the smoothness of the movement of the connecting plate Ⅰ 9.

[0028] In an embodiment of the present utility model, the driving mechanism includes a mounting plate 11 installed on the linear guide rail 5 and a cylinder 12 installed on the mounting plate 11. The axis of the cylinder 12 is arranged vertically, and the head end of the piston rod of the cylinder 12 is connected to the connecting plate Ⅰ 9. When the piston rod of the cylinder 12 extends outwards, it drives the connecting plate Ⅰ 9 to move down relative to the connecting plate Ⅱ 10. When the piston rod of the cylinder 12 retracts inwards, it drives the connecting plate Ⅰ 9 to move up relative to the connecting plate Ⅱ 10. The structure is simple and the operation is reliable.

[0029] In an embodiment of the present utility model, a connecting plate Ⅲ 13 fixed to the upper end of the cylinder 12 by a screw Ⅰ 14 is also included, and the upper end of the guide rod 24 is fixed to the connecting plate Ⅲ 13. By setting the connecting plate Ⅲ 13, the two-end support of the guide rod 24 is realized, improving the overall rigidity and ensuring the reliability of the up and down sliding of the connecting plate Ⅰ 9.

[0030] In an embodiment of the present utility model, the straw mechanism includes a vacuum suction cup 16 vertically installed on the connecting plate Ⅰ 9. A through hole 23 is vertically provided on the positioning block 21. When the connecting plate Ⅰ 9 moves to the lowermost end, the lower end of the vacuum suction cup 16 extends out from the through hole 23. After the controlled vial on the conveyor line 1 is conveyed in place, the connecting plate Ⅰ 9 moves downward, and the vacuum suction cup 16 extends out from the through hole 23 to suck the controlled vial on the conveyor line 1. Then, the driving mechanism drives the connecting plate Ⅰ 9 to move upward, and the controlled vial moves upward to the positioning groove 22 of the positioning block 21 under the adsorption and fixation of the vacuum suction cup 16.

Loosening the screw Ⅱ 20 can release the clamping force of the clamping block 19 on the pipe joint 17. At this time, the entire vacuum suction cup 18 can adjust its height position in the slot, which is convenient for adjusting to the elevation. After the adjustment is in place, tighten the screw Ⅱ 20 to make the clamping block 19 clamp and fix the pipe joint 17 part of the vacuum suction cup 18. The operation is convenient and simple.
