[0002] At present, the size detection of existing new material O-ring seals includes the process of accurately measuring and verifying the key geometric parameters of the seal rings. Most existing detection devices are equipped with industrial cameras and cooperate with specified algorithms to detect the size of the seal rings. However, in the actual application process, due to limitations such as algorithms and hardware, after the inner and outer diameters of the seal rings are detected by traditional detection devices, they directly transfer to the next process, and there is no corresponding mechanism to detect parameters such as the cross-sectional diameter and concentricity of the seal rings, resulting in the quality of O-ring seals not being guaranteed and the detection efficiency being low.

Detailed implementation manners
[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0018] Refer to Figures 1 - 4 、 Figure 11 , a detection device for a new material O-ring, including a cabinet 1. A fixed driving box 8 is installed inside the cabinet 1 through a mounting frame. One side of the fixed driving box 8 is rotatably connected to a self-rotating disk 3 through a bearing member. A plurality of detection tables 12 are installed on the self-rotating disk 3, and the detection tables 12 are used for assembling the sealing ring 111 for detection operations.
[0019] The self-rotating disk 3 is driven to rotate through a driving motor 6 and a pulley transmission mechanism. The driving motor 6 is installed inside the cabinet 1 through a mounting frame.
[0020] On one external side of the cabinet 1, a vibrating bowl 2 is installed through a mounting bracket. The discharging end of the vibrating bowl 2 is connected to a guiding belt 201. The guiding belt 201 guides and conveys the materials in the vibrating bowl 2. One end of the guiding belt 201 is connected to a correcting and twisting plate 202. The side of the correcting and twisting plate 202 facing the guiding belt 201 is inclined, and it is twisted from the side of the rotating disk 3 into a vertical posture. When the materials pass through the correcting and twisting plate 202, they will be corrected from an inclined posture to a vertical posture.
[0021] One end of the correcting and twisting plate 202 is connected to the feeding cylinder 9. An inclined channel 91 is opened in the middle of the feeding cylinder 9. The feeding cylinder 9 extends to the middle position of the rotating disk 3.
[0022] On one side of the lower oblique part of the rotating disk 3, an electric sorting plate 4 is arranged. The electric sorting plate 4 is driven by a motor to rotate. Below the electric sorting plate 4, a plurality of sorting bins 5 are arranged to collect materials.
[0023] Refer to Figure 5 , the pulley drive mechanism includes a driving pulley 61, a transmission belt body 62, and a transmission pulley 31. Among them, the output end of the driving motor 6 extends into the fixed driving box 8 and is connected to the driving pulley 61; At the central position inside the fixed driving box 8, a transmission pulley 31 is fixedly installed. The transmission pulley 31 and the driving pulley 61 are collinear on the horizontal projection plane, and a transmission belt body 62 is installed around the outside of the transmission pulley 31 and the driving pulley 61. When the driving pulley 61 rotates, the driving pulley 61 drives the transmission belt body 62 to move to drive the transmission pulley 31 to rotate.
[0024] Among them, the driving motor 6 is configured with a control module. Under the instruction of the control module, the driving motor 6 drives the rotating disk 3 through the pulley drive mechanism to perform an intermittent rotational movement of a single 90° rotation every 1 second.
[0025] Refer to Figures 6 - 10 , Figures 12 - 13 , Figure 22 , the upper part of the cabinet 1 is connected to the detection frame 10 through a pair of guiding columns 104. The detection frame 10 moves vertically through the guiding columns 104. A first spring 103 is connected between the detection frame 10 and the guiding columns 104. When the detection frame 10 moves vertically, the first spring 103 deforms.
[0026] Among them, a guiding cross bar 101 is horizontally installed on one side of the bottom of the detection frame 10. The guiding cross bar 101 extends towards the rotating disk 3.
[0027] On the other side of the bottom of the detection frame 10, a pressing block 102 is installed. A slot hole is opened in the middle of the pressing block 102, and a pressure sensing module 1021 is installed on the bottom wall of the pressing block 102.
[0028] On one side of the upper part of the detection table 12, a guide block 11 is installed. In the middle of the guide block 11, an inclined guide groove is opened, and the guide groove is used to dock with the guide cross bar 101; The guide cross bar 101 is located on the rotation path of the guide block 11. When the detection table 12 rotates synchronously with the guide block 11 to the detection frame 101, that is, the detection working area, the guide cross bar 101 is inserted into and docked with the guide groove in the middle of the guide block 11, and is in pressing contact with the upper wall of the guide groove, and is driven by the inclined plane. The guide cross bar 101 drives the entire detection frame 10 to move downward.
[0029] A connecting cylinder 32 is installed at the central position of the middle part of the turntable 3. The outer wall of the connecting cylinder 32 is connected to the detection table 12. A plurality of feeding ports 321 are penetrated through the inner wall of the connecting cylinder 32. Each feeding port 321 corresponds to and communicates with an inclined guide groove 122 opened in the middle of each detection table 12. The inclined guide groove 122 communicates with the feeding cavity 123 inside the detection table 12, and the bottom end of the feeding cavity 123 is penetrated.
[0030] A hollow suspension rod 15 is installed at the central position of the middle part of the feeding cavity 123. A guide rod 152 is installed in the middle of the upper end of the hollow suspension rod 15. An installation groove 121 is opened on one side away from the guide rod 152. A turning flap 14 is rotatably installed in the installation groove 121 through a pin shaft. One side of the turning flap 14 extends out of the installation groove 121 and is provided with a groove; A torsion spring 141 is arranged at the rotation connection part of the turning flap 14 and the installation groove 121. When the sealing ring 111 falls into the feeding cavity 123 through the inclined guide groove 122, the bottom of the sealing ring 111 contacts the upper part of the turning flap 14, and the turning flap 14 deflects downward due to free fall. At this time, the vertically falling sealing ring 111 changes to an inclined posture; Then, driven by the torsional force of the torsion spring 141, the turning flap 14 rotates and resets, so that the turning flap 14 resets into the installation groove 121 again.
[0031] The upper end of the inclined guide groove 122 penetrates through the middle part of the upper end of the detection table 12, and the lower end extends downward step by step at a fixed angle, and the end of the bottom end of the inclined guide groove 122 is connected and joined to the upper side wall of the upper end of the feeding cavity 123; Further, a pulse air pump 13 is installed on the upper part of the feeding cylinder 9 through a mounting frame. The air outlet end of the pulse air pump 13 is installed in an inclined channel 91 opened inside the feeding cylinder 9. The pulse air pump 13 is linked with the turntable 3 through an external PLC control unit. After each single 90° rotation and intermittent rotation movement of the turntable 3, the pulse air pump 13 is linked to perform a single jet, and then high-speed gas is sent into the feeding cavity 123.
[0032] Further, a plurality of hidden grooves 161 are formed in the inner wall of the loading cavity 123. The inner wall of the hidden groove 161 is rotatably installed with an attaching support plate 16 through a third torsion spring 7. In the natural state, the third torsion spring 7 generates a torsional force and drives the attaching support plate 16 to deflect towards the hollow suspension rod 15, and fits and is clamped into a clamping shallow groove 27 formed in the outer wall of the hollow suspension rod 15. The hollow suspension rod 15 is statically stable under the multi-directional support of multiple groups of attaching support plates 16.
[0033] Referring to Figure 14 , a second shielding ring 171 is installed inside the inspection table 12, and a plurality of annularly arrayed electromagnet groups 17 are assembled inside the second shielding ring 171. Each electromagnet group 17 faces the center position of the inspection table 12 at an upward angle of 30°.
[0034] When the electromagnet group 17 is energized to generate a static magnetic field, the magnetic force drives the hollow suspension rod 15 to float in the loading cavity 123. A laser displacement sensing module 25 is installed at the upper wall position of the loading cavity 123. The laser displacement sensing module 25 detects the displacement of the upper end face of the hollow suspension rod 15 on the horizontal projection plane, and after the displacement amount exceeds the corresponding threshold, the control module controls the electromagnet group 17 to generate a power change to form a dynamic magnetic field.
[0035] The multiple groups of electromagnet groups 17 arranged in an annular array cover the horizontal direction of the hollow suspension rod 15, and the inclined electromagnet groups 17 apply an oblique gradient magnetic field at an inclined angle.
[0036] Referring to Figures 15 - 19 , the hollow suspension rod 15 is made of a magnetic material. A plurality of second mounting grooves 1511 are formed on the outer side of the bottom of the hollow suspension rod 15 to assemble wedge-shaped limit blocks 151. A second torsion spring 1512 is arranged at the rotational connection of the wedge-shaped limit block 151 and the second mounting groove 1511. In the natural state, the second torsion spring 1512 drives the wedge-shaped limit block 151 to protrude outward through the torsional force, and when the wedge-shaped limit block 151 is forced to displace into the second mounting groove 1511, the second torsion spring 1512 rotates and deforms to generate a torsional reset force.
[0037] Further, a plurality of mounting cylinders 181 are installed in an annular array below the wedge-shaped limit block 151. One end of the mounting cylinder 181 extends into the hollow suspension rod 15 and is connected to a connecting ring 182. A concentric test head 18 is installed in the mounting cylinder 181 in a limited manner. One end of the concentric test head 18 extends out of the mounting cylinder 181, and the other end extends into the hollow suspension rod 15. A notch is formed in the middle of the concentric test head 18, and an elastic piece 26 is clamped at the notch. The elastic piece 26 is inclined, and the upper end of the elastic piece 26 is fixedly connected to the upper wall of the mounting cylinder 181. The bottom end of the elastic piece 26 always presses against the inner wall of the notch.
[0038] When the concentric test head 18 displaces within the installation cylinder 181, the relative position between the notch and the elastic piece 26 changes. The elastic piece 26 is extruded by the notch and deforms, and generates an opposite resilience force through its elastic property.
[0039] In addition, a groove is provided directly below the connecting ring 182 on the concentric test head 18. One side of the bottom of the connecting ring 182 is equipped with a first conductive sheet 23, and a second conductive sheet 24 is provided on the side directly opposite and away from the first conductive sheet 23. The second conductive sheet 24 is attached to the inner wall of the groove opened in the middle of the concentric test head 18. And when the concentric test head 18 displaces within the installation cylinder 181, the relative position between the groove and the second conductive sheet 24 changes. The second conductive sheet 24 is extruded by the inner wall of the groove and deforms until it contacts the first conductive sheet 23 to achieve circuit connection; The bottom ends of the first conductive sheet 23 and the second conductive sheet 24 both pass through the bottom of the connecting ring 182 and extend into the concentric test head 18. The first conductive sheet 23 and the second conductive sheet 24 are electrically connected to the Bluetooth single-chip microcomputer control module 21 through wires.
[0040] Among them, a set of the first conductive sheet 23 and the second conductive sheet 24 is correspondingly configured on one side inside each concentric test head 18, and each set of the first conductive sheet 23 and the second conductive sheet 24 is electrically connected to the Bluetooth single-chip microcomputer control module 21 through wires to form multiple independent excitation circuits.
[0041] The power supply module 211 is a button battery. The power supply module 211 is electrically connected to the Bluetooth single-chip microcomputer control module 21. A Bluetooth module is configured inside the Bluetooth single-chip microcomputer control module 21, and the Bluetooth single-chip microcomputer control module 21 is connected to control the electric sorting board 4.
[0042] Furthermore, one end of the concentric test head 18 extending into the hollow suspension rod 15 has a sloping wall 183, and the sloping wall 183 faces downward; A squeezing head 20 is installed on the bottom wall of the hollow suspension rod 15 in a limited sliding manner. The outer edges at both ends of the squeezing head 20 are rounded. One end of the squeezing head 20 extends into the hollow suspension rod 15 and is connected to the inside of the hollow suspension rod 15 through a second spring 22. When the squeezing head 20 is in squeezing contact with the squeezing block 102, the squeezing head 20 is displaced by the force, and the second spring 22 deforms.
[0043] During the displacement process of the squeezing head 20, the squeezing head 20 presses against the concentric test head 18 and drives the concentric test head 18 to displace horizontally through the sloping wall 183.
[0044] Furthermore, a pair of arc-shaped grooves 191 are formed in the bottom wall of the hollow suspension rod 15. The inner walls of the arc-shaped grooves 191 are connected with self-hanging hooks 19 through elastic ropes 192. The self-hanging hooks 19 are arc-shaped and are limited and slide within the arc-shaped grooves 191. A counterweight 193 is arranged at the top of the self-hanging hook 19. Under the self-weight of the counterweight 193, the self-hanging hook 19 naturally hangs downward along the arc-shaped groove 191.
[0045] The concentric test head 18 is arranged in a staggered manner with the self-hanging hook 19.
[0046] A partition is arranged at the inner bottom side of the hollow suspension rod 15 to assemble the second spring 22, the Bluetooth single-chip microcomputer control module 21, and the power supply module 211. A shielding ring 153 is installed on the inner wall of the concentric test head 18, and the shielding ring 153 covers the outside of the Bluetooth single-chip microcomputer control module 21 and the power supply module 211.
[0047] Refer to Figure 3 、 Figure 6 、 Figure 8 、 Figure 21 Below the electric sorting plate 4, two sorting bins 5 are arranged for sorting good products and defective products. In the natural state, the electric sorting plate 4 is inclined and introduces the materials into the good product bin. And when the electric sorting plate 4 rotates to be vertically downward, the materials are introduced into the defective product bin.
[0048] In this embodiment, the vibrating disk 2 is filled with the sealing rings 111 after the inner and outer diameters are detected. As the vibrating disk 2 operates and vibrates for feeding, the sealing rings 111 are gradually guided to a place on the guiding belt 201, and the attitude is corrected through the correction and twisting plate 202. When the sealing rings 111 are gradually corrected from the inclined attitude to the vertical attitude, the sealing rings 111 roll into the feeding cylinder 9, and are introduced into the feeding port 321 formed in the inner wall of the connecting cylinder 32 through the inclined channel 91 inside the feeding cylinder 9, and freely fall into the inspection table 12 in the feeding state; The pulse air pump 13 arranged at the upper part of the feeding cylinder 9 operates at this time and sends gas into the inside of the inspection table 12 to assist the sealing rings 111 in feeding.
[0049] At this time, the inspection table 12 is in the feeding working area. An inclined guiding groove 122 is formed in the middle of the inspection table 12 to guide the vertical sealing rings 111 to the side wall of the feeding cavity 123 in an inclined manner, and the sealing rings 111 fall on the flipping flap 14 along the inner wall of the feeding cavity 123. The flipping flap 14 receives the sealing rings 111. Under the action of the self-weight of the sealing rings 111, the flipping flap 14 is stressed and generates a downward deflection movement around its rotation axis, and the sealing rings 111 are gradually tilted and dumped from the vertical attitude, and under the action of the self-weight, they vertically fall downward in a nearly horizontal attitude, so as to be sleeved into the guiding rod 152, and under the guiding action of the guiding rod 152, they are sleeved outside the hollow suspension rod 15.
[0050] The feeding cavity 123 positions the outer wall of the sealing ring 111. The inner diameter of the sealing ring 111 is larger than the outer diameter of the hollow suspension rod 15, resulting in a gap between the hollow suspension rod 15 and the inner wall of the sealing ring 111.
[0051] The sealing ring 111 falls freely until it drops and makes extrusion contact with the outer wall of the wedge-shaped limiting block 151 at the bottom of the hollow suspension rod 15. The inclined surface of the wedge-shaped limiting block 151 is extruded and the whole deflects and displaces inward, allowing the sealing ring 111 to pass through. Subsequently, the hollow suspension rod 15 drops onto the self-hanging hook 19 and is supported by the self-hanging hook 19.
[0052] Then, the self-rotating disc 3 is driven by the driving motor 6 to rotate, driving the self-rotating disc 3 to rotate in the specified process direction. Then, the inspection table 12 after the feeding is completed, that is, the inspection table 12 in the feeding working area, is rotated to the vacant working area where no operation is performed, and the adjacent inspection tables 12 then sequentially enter the feeding working area to perform the feeding operation process of the sealing ring 111.
[0053] With the continuous intermittent rotation of the self-rotating disc 3, the inspection table 12 after the feeding is completed is docked with the guiding cross bar 101 provided at the bottom of the inspection frame 10. The guiding cross bar 101 moves downward under the guiding action of the guiding block 11, driving the extrusion block 102 and the inspection frame 10 as a whole to move downward and make extrusion contact with the extrusion head 20 on the upper part of the inspection table 12. The principle is the same as that of the side push slider in the stamping system, which is realized by the inclined surface drive and will not be explained again.
[0054] As the extrusion head 20 moves downward, different positional relationships are generated between the pressure sensing module 1021 provided on the bottom wall of the extrusion head 20 and the sealing ring 111 placed on the inspection table 12. Specifically: When the cross-sectional diameter of the sealing ring 111 is normal, the extrusion head 20 extrudes the upper wall of the sealing ring 111, and a corresponding electrical signal is generated through the pressure sensing module 1021 and a corresponding value is obtained after comparison to identify that the cross-sectional diameter of the sealing ring 111 is normal; When the cross-sectional diameter of the sealing ring 111 is larger than the normal value, the extrusion head 20 contacts and extrudes the upper wall of the sealing ring 111 prematurely and generates different pressure values. After comparison by the pressure sensing module 1021, a corresponding value is obtained and identified as an abnormal value; When the cross-sectional diameter of the sealing ring 111 is smaller than the normal value, the extrusion head 20 cannot make substantial contact with the upper wall of the sealing ring 111, and it is identified as an abnormal value after comparison by the pressure sensing module 1021.
[0055] Furthermore, when the sealing ring 111 is an abnormal value, the pressure sensing module 1021 drives the electric sorting plate 4 to rotate to the vertical state through the control module. When the self-rotating disc 3 drives the inspection table 12 to rotate to one side of the electric sorting plate 4, that is, the sorting working area, the defective materials fall into the defective product box.
[0056] Synchronized with the pressure sensing module 1021, the extrusion head 20 moved by the extrusion block 102 squeezes the inclined walls 183 of a plurality of concentric test heads 18 arranged inside the hollow suspension rod 15, and drives the plurality of concentric test heads 18 to synchronously extend outward through inclined guidance. At this time, different positional relationships are generated between the sealing ring 111 and the concentric test heads 18. Specifically: When the concentricity of the sealing ring 111 is within the normal value, at most one group of concentric test heads 18 contacts the inner wall of the sealing ring 111, and the remaining concentric test heads 18 all have gaps with the inner wall of the sealing ring 111; When the concentricity of the sealing ring 111 is an abnormal value, during the process of the concentric test heads 18 being pushed outwards, the concentric test heads 18 at different positions will contact the inner wall of the eccentric material. The distance between the concentric test heads 18 in the direction opposite to the eccentric direction of the eccentric material and the inner wall of the eccentric material will be smaller, so the concentric test heads 18 in this direction will make squeezing contact with the inner wall of the eccentric material; conversely, the concentric test heads 18 in the same direction as the eccentric direction have a certain gap with the other inner wall of the eccentric material.
[0057] Among them, during the displacement process of the concentric test heads 18, the concentric test heads 18 drive the corresponding second conductive sheets 24 to displace towards the side of the first conductive sheet 23. Since the conductive sheets are copper sheets, they have certain elasticity and flexibility; When the displacement amount reaches the corresponding threshold value, that is, when the concentric test heads 18 contact the inner wall of the eccentric material, the second conductive sheet 24 and the first conductive sheet 23 contact to form a connected circuit. At this time, the Bluetooth single-chip microcomputer control module 21 receives the corresponding electrical signal, and during a single detection process, after the number of electrical signals reaches the corresponding comparison trigger threshold value, the Bluetooth single-chip microcomputer control module 21 activates the electric sorting plate 4 to rotate to a vertical state. When the self-rotating disc 3 drives the detection table 12 to rotate to one side of the electric sorting plate 4, the defective materials fall into the defective product box.
[0058] Among them, during the rotation process of the self-hook 19 synchronously with the self-rotating disc 3, when the detection table 12 rotates to the horizontal state, that is, the vacant working area, the sealing ring 111 is in a vertical posture. At this time, the self-hook 19 can lock the sealing ring 111; When the detection table 12 rotates to the first position of the detection frame 10, that is, the detection working area, due to the setting of its counterweight 193, the self-hook 19 generates a vertically downward acting force due to gravity and naturally slides into the arc-shaped groove 191, and the self-hook 19 disengages from the sealing ring 111; When the detection table 12 continues to rotate to the first position of the electric sorting plate 4, that is, the sorting working area, under the action of static friction and the tension of the elastic rope 192, the self-hook 19 remains stationary and retracts into the arc-shaped groove 191. At this time, the sealing ring 111 naturally tilts and drops, and is sorted by the electric sorting plate 4.
[0059] When the detection table 12 continues to rotate to the vertically downward state, that is, the feeding work area, at this time, the gravity of the counterweight 193 is downward, and the whole arc-shaped groove 191 is vertically downward. The counterweight 193 drives the self-hanging hook 19 to hang down naturally, and the elastic rope 192 is straightened to support the sealing ring 111 during the feeding process.
[0060] Among them, during the rotational displacement process of the wedge-shaped limit block 151, the bottom wall of the wedge-shaped limit block 151 is a plane. When the wedge-shaped limit block 151 is displaced to a position on the detection frame 10, that is, the detection work area, the plane faces upward to support the sealing ring 111.
[0061] Among them, in the actual application process, a plurality of attached support plates 16 are provided on the outer side of the hollow suspension rod 15. The attached support plates 16 are torsionally attached and clamped in the outer wall hidden groove 161 of the hollow suspension rod 15 under the torsion of the third torsion spring 7. The clamping design of the groove body and the rod body ensures its stability in the natural state. And when a sealing ring 111 passes through, the attached support plate 16 deflects under force and allows the sealing ring 111 to pass through. Then, under the magnetic field suspension effect, the hollow suspension rod 15 remains in a suspended state; In the detection work area, the hollow suspension rod 15 pressed by the extrusion block 102 can also ensure the supportability through the clamping design of the groove body and the rod body.
[0062] The first shielding ring 153 and the second shielding ring 171 are used to shield the electromagnetic field and are made of magnetic shielding materials.
[0063] The feeding port 321 rotates with the self-rotating disc 3, and the feeding port 321 and the feeding cylinder 9 feed materials alternately.
[0064] The displacement of the extrusion head 20 drives the deformation of the second spring 22 to achieve reset and rebound.
[0065] As the self-rotating disc 3 rotates intermittently, the detection table 12 passes through different work areas to perform operations such as feeding, detection, and sorting. Furthermore, it can effectively detect the cross-sectional diameter and concentricity of the sealing ring 111, ensure the detection efficiency of the sealing ring 111, ensure the production quality, and solve the defect of lacking the detection of the cross-sectional diameter and concentricity in the traditional detection device.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
