Description

Technical Field

[0001] The present invention relates to the technical field of sealing ring size detection, in particular to a rubber sealing ring detection device. Background Art

[0002] In today's mechanical engineering, rubber sealing rings are required in many occasions. Although rubber sealing rings are not expensive, their size must be guaranteed in key positions. If the rubber sealing ring is too small, it will lead to loose sealing, seal failure, liquid or gas leakage, and thus affect system performance; while if the rubber sealing ring is too large, the seal will be over-stretched or over-extended, which will easily cause cracks and leakage. In the past, the common inspection method on the production line was to use a micrometer or caliper to measure the cross-sectional dimensions and thickness of the rubber sealing ring. Multiple inspection points (6-10) were selected along the circumference of the sealing ring, and the acceptance was determined based on the test results. However, long-term operation can easily cause fatigue, so random inspections are usually carried out according to the production quantity and sampling standards. This leads to problems such as missed inspections and high manual labor intensity. In addition, rubber sealing rings have a certain degree of elasticity, making manual inspections prone to errors. To this end, a disclosed technology proposes an integrated sealing ring shape and pressure detection device, which includes a detection platform, a material grabbing component, a visual detection component, a feeding component, a pressure detection component, and an automatic detection system; the material grabbing component is located on one side of the detection platform, and is used to grab the sealing ring that needs to be detected; the visual detection component is located on one side of the material grabbing component, facing the detection platform; the feeding component is located on one side of the visual detection component, and receives the sealing ring after detection; the pressure detection component is located on one side of the feeding component, extending to the top of the feeding component, and performs pressure detection on the sealing ring. The disclosed technology states that the integrated sealing ring shape and pressure detection device it provides can achieve comprehensive detection of the sealing ring through automatic switching of two workstations. The visual detection component can directly detect the shape and size of the sealing ring, while the pressure detection component determines whether it is qualified based on the degree of damage to the colored coating after being subjected to force. The above-mentioned public technology uses a visual inspection component to detect the projected size of the O-ring, and can obtain the cross-sectional diameter, inner diameter and outer diameter. However, when applied to a bidirectional sealing rubber ring, the thickness part cannot be inspected, and when detecting the outer size, the sealing ring is clamped toward the center by the positioning jaws, and then inspected. As mentioned above, the sealing ring is elastic, and the sealing ring will inevitably be deformed after being clamped by the positioning jaws. At this time, the inspection result will inevitably be inconsistent with the actual situation, so the above-mentioned technology is contrary to the facts. In addition, the above-mentioned technology uses a feeding seat to move the feeding to eliminate unqualified products, and the movement is slow, which affects the overall inspection efficiency. In summary, in order to conveniently and efficiently detect the thickness size of the bidirectional sealing rubber ring, it is necessary to develop a rubber sealing ring detection device.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: like Figures 1 to 14As shown, an embodiment of the present invention provides a rubber sealing ring detection device, including a sealing ring body 14, a base 1, an air compressor, a vacuum pump and multiple sets of laser rangefinders 26. Four sets of support feet 2 for adjusting the level of the upper wall of the base 1 are fixedly connected to the bottom of the base 1. A detection table 3 is fixedly connected to the upper wall of the base 1. The center of the upper wall of the detection table 3 is the detection center. In this embodiment, the thickness of the sealing ring body 14 is mainly automatically measured at multiple points. The external dimensions can be detected simultaneously with the thickness detection using the visual sensor proposed in the public technology. The structure of the visual sensor for detecting the external dimensions is not described in detail in this embodiment. In order to facilitate the thickness measurement of the sealing ring body 14 of different thicknesses, the upper wall of the base 1 is slidably connected to the top plate 6 through a first adjusting structure. The first adjusting structure includes four groups of fixed sleeves 4 and support rods 5. The four groups of fixed sleeves 4 are fixedly connected to the front wall and the rear wall of the base 1 in pairs of twos, and the four groups of support rods 5 are fixedly connected to the front wall and the rear wall of the top plate 6 in pairs of twos, and the four groups of support rods 5 are respectively opposite to the four groups of fixed sleeves 4 in upper and lower directions. The lower ends of the support rods 5 pass through the upper wall of the fixed sleeve 4 opposite to the upper and lower directions. An electric telescopic rod 19 is provided between the inner lower wall of the fixed sleeve 4 and the lower end of the support rod 5. The electric telescopic rod 19 extends and retracts the shaft, which can drive the top plate 6 to rise and fall, and then drive the laser ranging head 26 located at the bottom of the top plate 6 to rise and fall. The height position of the laser ranging head 26 can be conveniently adjusted for sealing ring bodies 14 of different thicknesses. In order to detect the thickness of the sealing ring body 14, the upper wall of the top plate 6 is detachably connected to the upper cover 7, and the inner wall of the top plate 6 is provided with multiple groups of vertically penetrating slide grooves 25. The multiple groups of slide grooves 25 are evenly distributed on the circumference with the detection center as the center when projected from above, and the extension lines of the length direction of the slide grooves 25 all intersect with the detection center. Multiple groups of laser ranging heads 26 are slidably connected to the inner side walls of the multiple groups of slide grooves 25. During detection, the multiple groups of laser ranging heads 26 simultaneously detect multiple points on the upper surface of the sealing ring body 14. The thickness of the sealing ring body 14 is obtained by subtracting the distance between the laser ranging head 26 and the detection table 3 from the distance between the laser ranging head 26 and the upper surface of the sealing ring body 14. The thickness detection can be divided into three results: too large thickness, qualified thickness, and too small thickness. In order to be able to detect sealing ring bodies 14 of different diameters, a second adjustment structure is provided on the upper wall of the top plate 6 for driving the laser ranging head 26 to slide along the inner wall of the slide groove 25 to adjust the detection range. The second adjustment structure includes a linear motor 27 and a connecting seat 28. The linear motor 27 is fixedly connected to the upper wall of the top plate 6 and is located on one side of the slide groove 25. The length direction of the linear motor 27 is parallel to the length direction of the slide groove 25. The connecting seat 28 is fixedly connected to the upper wall of the linear motor 27 and one end of the connecting seat 28 extends toward the top of the slide groove 25. The laser ranging head 26 is fixedly connected to the lower wall of the connecting seat 28 extending to the end above the slide groove 25. The linear motor 27 is a micro linear motor with a self-locking mechanism that is more common on the market. When it is in action, it can drive the laser ranging head 26 to slide along the length direction of the slide groove 25, thereby causing multiple groups of laser ranging heads 26 to move closer to or away from each other, thereby achieving the purpose of detecting sealing ring bodies 14 of different diameters. In order to facilitate feeding, a loading drive box 8 is fixedly connected to the left wall of the base 1 and close to the lower wall. A screw 15 is rotatably connected inside the loading drive box 8. The upper end of the screw 15 passes through the upper wall of the loading drive box 8 and extends above the loading drive box 8. The horizontal height of one end of the screw 15 extending above the loading drive box 8 is consistent with the horizontal height of the detection table 3. A feeding structure for feeding is provided between the end of the screw 15 extending above the loading drive box 8 and the upper wall of the loading drive box 8. The feeding structure includes a guide tube 10, a supporting nut 17 and two sets of anti-rotation rods 16.

The axis of the guide tube 10 is collinear with the axis of the screw 15. The supporting nut 17 is threadedly connected to the outer wall of the screw 15 and the supporting nut The outer wall of the nut 17 is slidably connected to the inner wall of the guide tube 10, and the two sets of anti-rotation rods 16 are fixedly connected to the upper wall of the feeding drive box 8 and are respectively located on the left and right sides of the screw 15. The ends of the two sets of anti-rotation rods 16 away from the feeding drive box 8 pass through the inner wall of the supporting nut 17 and are slidably connected thereto. In the initial state, the supporting nut 17 is located at the bottom of the guide tube 10. Multiple sets of sealing ring bodies 14 to be tested are stacked inside the guide tube 10 and above the supporting nut 17. The screw 15 rotates several times to drive the supporting nut 17 to rise a stroke to provide a sealing ring body 14 to the vacuum suction cup 13, so that the vacuum suction cup 13 maintains the same suction height each time. The process of placing multiple sets of sealing ring bodies 14 into the guide tube 10 can be carried out by feeding through the spiral vibrating disk proposed by the publicly available technology on the market; In order to realize the rising or falling action of the supporting nut 17, the feeding drive box 8 is also provided with a feeding drive for driving the screw 15 to rotate to drive the feeding structure to feed the material. The feeding drive includes a servo motor 9 and two sets of gears 18. The servo motor 9 is fixedly connected to the upper wall of the feeding drive box 8 and is located in front of the screw 15. The servo motor 9 extends a shaft that penetrates the upper wall of the feeding drive box 8 and extends to the inside of the feeding drive box 8. The two sets of gears 18 are respectively fixedly connected to the outer wall of the extended shaft of the servo motor 9 and the outer wall of one end of the screw 15 located inside the feeding drive box 8. The circumferential outer walls of the two sets of gears 18 are meshed with each other. When the servo motor 9 rotates, the screw 15 is driven to rotate through the mutual meshing relationship of the two sets of gears 18. When the screw 15 rotates, the supporting nut 17 is driven, but the supporting nut 17 is restricted by the two sets of anti-rotation rods 16 and can only move along the axial direction of the screw 15, but cannot rotate. When the screw 15 rotates, the supporting nut 17 is driven to rise or fall; In order to transfer the sealing ring body 14 from above the support nut 17 to above the detection table 3, a translation manipulator 11 is provided on the left wall of the base 1 and located behind the screw 15 through a fixed frame. The end of the shaft extending from the translation manipulator 11 is connected to a vacuum suction cup 13 for adsorbing the material through a first cylinder 12. The bottom of the vacuum suction cup 13 is provided with multiple groups of adsorption holes, which adsorb the upper surface of the sealing ring body 14 for transfer. The vacuum suction cup 13 of the corresponding size can be replaced according to the different sizes of the sealing ring body 14. The vacuum suction cup 13 is connected to the vacuum pump through an air pipe; After the inspection is completed, in order to achieve the purpose of rapid discharge, the upper wall of the inspection table 3 and the front, rear and left sides of the inspection center are provided with step grooves 301, the inner lower walls of the three groups of step grooves 301 are provided with through holes 302 that penetrate the inside of the base 1, the inner wall of the through hole 302 is slidably connected with a guide ring 24, and the upper wall of the guide ring 24 is fixedly connected with a blowing box 20, and a blowing structure is provided inside the blowing box 20. The blowing structure includes three groups of blowing cavities 2001 and air pipe joints 21. The three groups of blowing cavities 2001 are respectively arranged in the three groups of blowing boxes 20 and are respectively connected to the side of the three groups of blowing boxes 20 facing the inspection center. The three groups of air pipe joints 21 are respectively fixedly connected to the lower walls of the three groups of blowing boxes 20 and are respectively connected to the three groups of The inside of the air blowing cavity 2001 is connected, and one end of the three groups of air pipe joints 21 away from the blowing box 20 is connected to the air compressor through the air pipe. The outer wall of the blowing box 20 is slidably connected to the inner wall of the step groove 301. When the lower wall of the blowing box 20 is pressed against the inner lower wall of the step groove 301, the upper surface of the blowing box 20 is flush with the upper wall of the detection table 3. After the inspection is completed, the sealing ring body 14 located at the detection center raises the blowing box 20 in the corresponding direction according to the judgment result, and compressed air is provided by the air compressor. The compressed air is blown toward the sealing ring body 14 along the air pipe, the air pipe joint 21 and the air blowing cavity 2001, and the sealing ring body 14 is blown away to realize discharging. The surface of the detection table 3 is a smooth surface, which will not cause wear of the sealing ring body 14. In order to ensure that the blowing box 20 is raised only when blowing is needed, a blowing drive for driving the blowing box 20 to rise and fall is provided between the lower wall of the blowing box 20 and the detection table 3. The blowing drive includes a bracket 22 and a third cylinder 23. The bracket 22 is fixedly connected to the lower wall of the detection table 3 and is opposite to the through hole 302 in upper and lower directions. The third cylinder 23 is fixedly connected to the lower wall of the inner side of the bracket 22. The end of the extended shaft of the third cylinder 23 is fixedly connected to the lower wall of the blowing box 20. The extended shaft of the third cylinder 23 is extended and retracted, which can drive the blowing box 20 to rise and fall from the step groove 301. After lowering, the upper surface of the blowing box 20 is flush with the upper wall of the detection table 3, without affecting the blowing action in other directions. In order to collect the sealing ring bodies 14 with different inspection results, the front wall, rear wall and right wall of the base 1 are provided with a material receiving structure for receiving the material when the blowing drive is used. The material receiving structure includes three groups of material receiving pipes 29, and the three groups of material receiving pipes 29 are respectively fixedly connected to the front wall, rear wall and right wall of the base 1. The material receiving ports of the three groups of material receiving pipes 29 are all facing the detection center. The inner wall of the material receiving pipe 29 is fixedly connected with a buffer layer 2901. The three groups of material receiving pipes 29 collect the sealing ring bodies 14 with three different inspection results from three directions respectively, which can physically prevent the sealing ring bodies 14 with different inspection results from being mixed together again, effectively improving product safety. The buffer layer 2901 can play a buffering role when receiving the sealing ring body 14.

[0021] Working principle: In this embodiment, the thickness of the sealing ring body 14 is mainly measured automatically at multiple points. The external dimensions can be detected synchronously when detecting the thickness using the visual sensor proposed in the public technology. In this embodiment, the structure of the visual sensor detecting the external dimensions is not described in detail. The electric telescopic rod 19 extends and retracts the shaft, which can drive the top plate 6 to rise and fall, and then drive the laser ranging head 26 located at the bottom of the top plate 6 to rise and fall. The height position of the laser ranging head 26 can be conveniently adjusted for sealing ring bodies 14 of different thicknesses. During detection, multiple groups of laser ranging heads 26 simultaneously detect multiple points on the upper surface of the sealing ring body 14, and the distance between the laser ranging head 26 and the detection table 3 is subtracted from the distance from the laser ranging head 26 to the sealing ring body 14. The distance between the upper surfaces of the ring body 14 is the thickness of the sealing ring body 14. The thickness detection can be divided into three results: too large thickness, qualified thickness and too small thickness. The linear motor 27 is a micro linear motor with a self-locking mechanism that is more common on the market. When it is in motion, it can drive the laser ranging head 26 to slide along the length direction of the slide groove 25, thereby causing multiple groups of laser ranging heads 26 to move closer to or away from each other, thereby achieving the purpose of detecting sealing ring bodies 14 of different diameters. In the initial state, the supporting nut 17 is located at the bottom of the guide tube 10. Multiple groups of sealing ring bodies 14 to be detected are stacked inside the guide tube 10 and above the supporting nut 17. The screw 15 is rotated several times to drive the supporting nut 17 to rise a stroke to move toward the vacuum suction cup 13. A sealing ring body 14 is provided so that the vacuum suction cup 13 can maintain the same material suction height each time. The process of placing multiple sets of sealing ring bodies 14 into the material guide tube 10 can be carried out by feeding through the spiral vibration disk proposed by the publicly available technology on the market. When the servo motor 9 rotates, the screw 15 is driven to rotate through the mutual meshing relationship of the two sets of gears 18. When the screw 15 rotates, it drives the supporting nut 17, but the supporting nut 17 is restricted by the two sets of anti-rotation rods 16 and can only move along the axial direction of the screw 15, and cannot rotate. When the screw 15 rotates, the supporting nut 17 is driven to rise or fall. Multiple sets of adsorption holes are provided at the bottom of the vacuum suction cup 13, which adsorb the upper surface of the sealing ring body 14 for transfer. The vacuum suction cup 13 of the corresponding size can be replaced according to the different sizes of the sealing ring body 14. The vacuum suction cup 13 is connected to the vacuum pump through the air pipe. After the inspection of the sealing ring body 14 located in the inspection center is completed, the blowing box 20 in the corresponding direction is raised according to the judgment result. The compressed air is provided by the air compressor. The compressed air is blown to the sealing ring body 14 along the air pipe, the air pipe joint 21 and the blowing cavity 2001, and the sealing ring body 14 is blown away to realize the discharge. The surface of the inspection table 3 is a smooth surface, which will not cause wear of the sealing ring body 14. The third cylinder 23 extends and retracts the shaft, which can drive the blowing box 20 to rise and fall from the step groove 301. After lowering, the upper surface of the blowing box 20 is flush with the upper wall of the inspection table 3, which does not affect the blowing action in other directions. The three sets of material receiving pipes 29 are fixedly connected to the front wall, rear wall and right wall of the base 1 respectively.The three sets of receiving pipes 29 all face the inspection center. A buffer layer 2901 is fixedly attached to the inner wall of the pipes 29. The three sets of receiving pipes 29 collect three different types of seal ring bodies 14 with different inspection results from three different directions. This physically prevents seal ring bodies 14 with different inspection results from being mixed together, effectively improving product safety. The buffer layer 2901 acts as a buffer when receiving the seal ring bodies 14.
