Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, specifically to a symmetrical testing device for vulcanized capsules. Background Technology

[0002] Application number CN201610857199.9 discloses a device and method for detecting the symmetry of vulcanized bladders. In the background section, it mentions that in the prior art, the symmetry detection of tire vulcanized bladders often relies on manual touch or visual inspection by experienced craftsmen. This method introduces a large degree of subjectivity and random uncertainty into the detection of vulcanized bladder symmetry, which is a challenge and also makes it impossible to objectively and accurately determine the symmetry of vulcanized bladders.

[0003] The invention involves fitting a vulcanizing capsule 9 onto a sleeve post 5, with the bottom and top ends of the capsule 9 respectively inserted into the lower annular groove 41 and the upper annular groove 51. Two retaining rings 6 are then inserted into the lower and upper annular grooves 41 and 51 to clamp and seal both ends of the vulcanizing capsule 9. High-pressure air is introduced into the air passage 52 of the sleeve post 5 through an air pipe to inflate the sealed space 8, causing the vulcanizing capsule 9 to expand. After expansion, the probe of the grating sensor 7 is brought close to the outside of the expanded capsule 9. The turntable 4 is driven to rotate, simultaneously acquiring and analyzing the measurement data from the grating sensor 7. Simultaneously, a rotary encoder detects the rotation angle of the turntable; in this embodiment, two points are collected for every quarter-turn of the encoder disk, and eight points are collected for one full rotation. By detecting the change in the spacing of the stripes on the outer surface of the vulcanizing capsule 9, the distance between the outer surface of the vulcanizing capsule 9 and the probe of the grating sensor 7 is determined, and corresponding data is transmitted to the controller for analysis.

[0004] Since the initial product of the tire, namely the vulcanized bladder, is made by injection molding in half along the axial direction using a vulcanizing machine, its symmetry is necessarily in the axial direction of the vulcanized bladder. However, the invention described above inflates the vulcanized bladder with high pressure. Because the vulcanized bladder is made of rubber, it has high plasticity. The inflated vulcanized bladder will resist some of the asymmetry caused by the manufacturing process, resulting in an inaccurate symmetry test. Therefore, it is necessary to analyze the symmetry by unfolding the vulcanized bladder in half along the axial direction to achieve accurate results. Summary of the Invention

[0005] In order to overcome the defects in the prior art, the purpose of this invention is to provide a symmetrical detection device for vulcanized capsules to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a symmetrical detection device for vulcanized capsules, comprising a frame and industrial cameras symmetrically suspended on its top, a detection group being arranged in the middle of the frame, a conveyor belt being arranged below the detection group, and a feeding group and a discharging group being arranged at both ends of the conveyor belt, respectively.

[0007] The detection group includes a main measuring wheel suspended between a pair of industrial cameras, a stepper motor for driving the main measuring wheel to rotate, and a secondary measuring wheel suspended directly below the main measuring wheel and capable of engaging with the vulcanizing capsule. The outer side of the main measuring wheel has a pressure groove with a trapezoidal cross-section, and an opening is provided on one radial side of the main measuring wheel. The arc length of the pressure groove is equal to the circumference of the vulcanizing capsule. The middle part of the secondary measuring wheel is convex and engages with the pressure groove at intervals.

[0008] The conveyor belt extends axially along the main measuring wheel. Side belts are bonded to the sides of the conveyor belt and are arranged obliquely upward. Baffles are bonded to the top surface of one end of the conveyor belt and the bottom surface of the other end. A servo motor is coaxially connected to one end of the conveyor belt. The baffles are located in the middle of the conveyor belt and are biased towards its front side.

[0009] The feeding assembly includes a support roller sleeve that is fitted to the left end of the auxiliary measuring wheel, a spring placed between the support roller sleeve and the left end of the auxiliary measuring wheel, and a feeding frame that is fitted to the left end of the support roller sleeve.

[0010] The feeding assembly includes a baffle plate sleeved on the right end of the auxiliary measuring wheel, a feeding frame for supporting the baffle plate, and a compression spring for rebounding the baffle plate. The baffle plate is located directly above the right end of the conveyor belt.

[0011] As a further improvement to this technical solution, a rotating shaft that is sleeved with the main measuring wheel is inserted between the top of the frame, the stepper motor is fixedly connected to the top surface of the frame by bolts, large pulleys are sleeved at both ends of the rotating shaft, a small pulley is coaxially connected to the output shaft of the stepper motor, and a belt is sleeved between the large pulley and the small pulley.

[0012] As a further improvement to this technical solution, a clearance groove is provided on one radial side of the middle part of the auxiliary measuring wheel. The interior of the auxiliary measuring wheel has a hollow structure and load-bearing blocks are symmetrically welded on both sides of the clearance groove. The outer diameter of the middle part of the auxiliary measuring wheel is smaller than the inner diameter of the opening on the side of the vulcanizing capsule. The distance between the top surface of the conveyor belt and the central axis of the auxiliary measuring wheel is equal to the radius of the vulcanizing capsule.

[0013] As a further improvement to this technical solution, the left end of the auxiliary measuring wheel extends to provide a connecting post that is sleeved with the right end of the support wheel sleeve. The side of the connecting post is provided with a guide groove from left to right, and the inner wall of the right end of the support wheel sleeve is embedded with a guide post that is engaged with the guide groove and can slide.

[0014] As a further improvement to this technical solution, the length of the connecting column is greater than the length of the roller sleeve, and the length of the roller sleeve is greater than the axial width of the vulcanizing capsule.

[0015] As a further improvement to this technical solution, the left end of the guide groove is located on the side of the connecting column, the right end of the guide groove is located on the top surface of the connecting column, and the included angle between the two ends of the guide groove after axial projection is 90 degrees.

[0016] As a further improvement to this technical solution, a linkage rod is welded to the bottom left end of the support roller sleeve. The linkage rod consists of a straight section and an arc section, and the arc section extends to the other side of the guide post. A round shaft that fits into the support roller sleeve is inserted into the top of the feeding frame, and a limit block is fitted in the middle of the round shaft.

[0017] As a further improvement to this technical solution, the arc segment of the linkage rod can slide into contact with the baffle during the upward and rightward movement process, and straight plates are welded to the upper and lower surfaces of the baffle plate, with the lower straight plate being able to slide into contact with the baffle during the rightward and downward movement process.

[0018] As a further improvement to this technical solution, a sliding rod that is sleeved on the top of the unloading frame is inserted into the center of the baffle plate, a limiting ring is sleeved in the middle of the sliding rod, and the compression spring is located between the limiting ring and the unloading frame.

[0019] As a further improvement to this technical solution, a downwardly inclined feeding plate is provided at the right end of the frame and below the right end of the conveyor belt. A guide frame is welded below the top surface of the right end of the frame. A pair of guide rods are inserted into the top of the limiting ring, passing through the guide frame and the straight plate above the baffle plate from right to left.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The symmetrical detection device for the vulcanized capsule uses a set detection group to place the vulcanized capsule on the auxiliary measuring wheel. The capsule is rolled by the main measuring wheel, causing its two sides to extend and spread on the shaft of the main measuring wheel. Then, an industrial camera between the main measuring wheels takes a picture of the trajectory of the vulcanized capsule's edge spreading after one rotation, and compares it with a standard picture to determine the size of the error. This ensures symmetrical comparison along the axis of the vulcanized capsule and improves the accuracy of the detection.

[0022] 2. The symmetrical detection device for the vulcanized capsule, through the set feeding group, starts the servo motor to drive the conveyor belt to circulate. When the baffle rotates to its left end, the baffle flips up and moves to the right to contact the arc segment of the linkage rod, pushing the roller sleeve into the connecting column, thereby opening the break with the feeding frame, so that the vulcanized capsule can be placed at the left end of the conveyor belt and lean against the baffle. Under the rebound action of the spring, the roller sleeve is reset and sleeved with the feeding frame, forming a support for the auxiliary measuring wheel.

[0023] 3. The symmetrical testing equipment for the vulcanized capsules uses a set feeding group to start a servo motor to drive the conveyor belt. When the vulcanized capsule moves to the right end of the conveyor belt, the baffle will first contact the straight plate below the baffle plate and push the baffle plate. Before the baffle plate separates from the baffle plate at the bend, the vulcanized capsule rolls out of the conveyor belt along the gap between the auxiliary test wheel and the baffle plate and the feed plate and is collected. At this time, another baffle also moves to the left end of the conveyor belt at the bend. The staff continues to put in vulcanized capsules according to the above operation, thus forming a continuous testing process. Attached Figure Description

Furthermore, in the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0047] Please see Figures 1-14 As shown, this invention provides a symmetrical detection device for vulcanized capsules, including a frame 100 and an industrial camera 110 symmetrically suspended on its top. The industrial camera, also known as an industrial video camera, has high image stability, high transmission capability, and high anti-interference capability. The industrial camera is generally installed on a machine assembly line to replace the human eye for measurement and judgment. It captures the target through digital image and converts it into image signals, which are then transmitted to a dedicated image processing system. The image system performs various calculations on these signals to extract the features of the target, and then displays the error between the captured image and the standard image on the display based on the judgment result.

[0048] Specifically, a detection group 200 is set in the middle of the frame 100, and a conveyor belt 300 is set below the detection group 200 for automatically conveying the vulcanized capsules into the detection group 200 for detection; a feeding group 400 and a discharging group 500 are respectively set at both ends of the conveyor belt 300 to support the detection group 200 to clamp the vulcanized capsules and rotate them, and the industrial camera 110 captures the edge trajectory map of the vulcanized capsule after clamping it for one revolution, and then compares it with the standard image to determine the size of the error.

[0049] Furthermore, the detection group 200 includes a main test wheel 210 suspended between a pair of industrial cameras 110, a stepper motor 220 for driving the main test wheel 210 to rotate, and a secondary test wheel 230 suspended directly below the main test wheel 210 and can be fitted with the vulcanizing capsule. The vulcanizing capsule is clamped by the main test wheel 210 and the secondary test wheel 230 and rolled out symmetrically to obtain the edge trajectory of the side of the vulcanizing capsule. Then, the industrial cameras capture and record images on both sides of the main test wheel 210.

[0050] The outer side of the main measuring wheel 210 is provided with a pressure groove 211 with a trapezoidal cross-section, and an opening 212 is provided on one radial side of the main measuring wheel 210. Initially, the opening 212 faces downward so that the vulcanizing capsule on the conveyor belt 300 is transported between the auxiliary measuring wheel 230 and the opening 212. The arc length of the pressure groove 211 is equal to the circumference of the vulcanizing capsule, that is, the main measuring wheel 210 can roll the vulcanizing capsule on the auxiliary measuring wheel 230 for one rotation, so that its edge trajectory can be completely captured. The middle part of the auxiliary measuring wheel 230 is convex and interlocks with the pressure groove 211 at intervals, so that the tire-shaped vulcanizing capsule is rolled and spread out on both sides to detect the symmetry of the molded vulcanizing capsule.

[0051] Furthermore, the conveyor belt 300 extends axially along the main measuring wheel 210, and an upwardly angled side strip 310 is bonded to the side of the conveyor belt 300 to hold the vulcanizing capsules and form a support; baffles 320 are bonded to the top surface of one end of the conveyor belt 300 and the bottom surface of the other end, so that the two baffles 320 operate alternately, which facilitates the loading and unloading of vulcanizing capsules at both ends of the conveyor belt and saves production time; a servo motor 330 is coaxially connected to one end of the conveyor belt 300 to drive the conveyor belt 300 to circulate and transport the vulcanizing capsules.

[0052] The baffle 320 is located in the middle of the conveyor belt 300 and is biased towards its front side. When the baffle 320 moves on the top surface of the conveyor belt 300, it serves to support the vulcanizing capsule and keep it upright. When the baffle 320 rotates to the right end of the conveyor belt 300, it can form a bottom support for the vulcanizing capsule when it bends. Since the baffle 320 is not set in the center, the center of gravity of the vulcanizing capsule is shifted so that it can automatically roll out from the right end of the conveyor belt 300 to complete the unloading.

[0053] Furthermore, the feeding assembly 400 includes a support roller sleeve 410 that is sleeved on the left end of the auxiliary measuring wheel 230, a spring 420 placed between the support roller sleeve 410 and the left end of the auxiliary measuring wheel 230, and a feeding frame 430 that is sleeved on the left end of the support roller sleeve 410. The spring 420 presses the support roller sleeve 410 to engage with the feeding frame 430, thereby providing support for the auxiliary measuring wheel 230 when it rotates.

[0054] The feeding assembly 500 includes a baffle plate 510 sleeved with the right end of the auxiliary measuring wheel 230, a feeding frame 540 for supporting the baffle plate 510, and a compression spring 530 for rebounding the baffle plate 510. The compression spring 530 presses the baffle plate 510 against the right end of the auxiliary measuring wheel 230 to ensure its normal rotation.

[0055] The baffle plate 510 is located directly above the right end of the conveyor belt 300. When the baffle plate 320 moves to the right end with the conveyor belt 300, it contacts the baffle plate 510 and pushes the right end of the auxiliary measuring wheel 230, forming a notch for the vulcanizing capsule to be removed. A downwardly inclined feed plate 120 is provided at the right end of the frame 100 and below the right end of the conveyor belt 300, so that the vulcanizing capsule automatically rolls out of the conveyor belt 300 along the feed plate 120.

[0056] Specifically, a rotating shaft 111 is inserted into the top of the frame 100 and sleeved with the main measuring wheel 210. A stepper motor 220 is fixedly connected to the top surface of the frame 100 by bolts. Large pulleys are sleeved at both ends of the rotating shaft 111. A small pulley is coaxially connected to the output shaft of the stepper motor 220. A belt is sleeved between the large pulley and the small pulley. When the stepper motor 220 is started, it drives the rotating shaft 111 to drive the main measuring wheel 210 to rotate one revolution each time.

[0057] Specifically, a clearance groove 231 is provided on one radial side of the middle part of the auxiliary measuring wheel 230 to allow the baffle 320 to pass; the interior of the auxiliary measuring wheel 230 is hollow and load-bearing blocks are symmetrically welded on both sides of the clearance groove 231, so that the auxiliary measuring wheel 230 can stop after rotating one revolution and the clearance groove 231 faces downward.

[0058] The outer diameter of the middle part of the auxiliary measuring wheel 230 is smaller than the inner diameter of the side opening of the vulcanizing capsule. The distance between the top surface of the conveyor belt 300 and the central axis of the auxiliary measuring wheel 230 is equal to the radius of the vulcanizing capsule, so that the vulcanizing capsule can be smoothly fitted onto the auxiliary measuring wheel 230 along the conveyor belt 300.

[0059] It is worth noting that the left end of the auxiliary measuring wheel 230 extends to provide a connecting post 232 that is sleeved with the right end of the support wheel sleeve 410. The side of the connecting post 232 is provided with a guide groove 233 from left to right. The inner wall of the right end of the support wheel sleeve 410 is embedded with a guide post 412 that is engaged with the guide groove 233 and can slide. When the baffle plate 510 retracts from the right end of the auxiliary measuring wheel 230, the guide post 412 and the left end of the guide groove 233 limit the auxiliary measuring wheel 230 from shifting relative to the main measuring wheel 210.

[0060] The length of the connecting column 232 is greater than the length of the roller sleeve 410, allowing the roller sleeve 410 and the spring 420 to move to the right; the length of the roller sleeve 410 is greater than the axial width of the vulcanizing capsule, allowing the vulcanizing capsule to be smoothly placed on the left end of the conveyor belt 300, and its central axis to be placed in conjunction with the central axis of the auxiliary measuring wheel 230.

[0061] Specifically, such as Figure 13 As shown, the left end of the guide groove 233 is located on the side of the connecting post 232, the right end of the guide groove 233 is located on the top surface of the connecting post 232, and the included angle between the two ends of the guide groove 233 after axial projection is 90 degrees.

[0062] A linkage rod 411 is welded to the bottom left end of the roller sleeve 410. The linkage rod 411 consists of a straight section and an arc section, and its arc section extends to the other side of the guide post 412. A round shaft that fits into the roller sleeve 410 is inserted into the top of the feeding rack 430, and a limit block 431 is fitted in the middle of the round shaft. The limit block 431 is used to limit the position of the roller sleeve 410 rebounding by the spring 420, so that the baffle 320 flipped up at the left end of the conveyor belt 300 can contact the arc section of the linkage rod 411, and push the roller sleeve 410 into the connecting post 232, thereby opening the break with the feeding rack 430, so that the vulcanizing capsule can be placed at the left end of the conveyor belt 300 and lean against the baffle 320.

[0063] The arc segment of the linkage rod 411 can slide into contact with the baffle 320 during the upward and rightward movement. The outer diameter of the arc segment of the linkage rod 411 is smaller than the diameter of the opening on the side of the vulcanizing capsule. Since the guide post 412 will slide from its left end to its right end along the guide groove 233, the arc segment of the linkage rod 411 will rotate forward again when it is pushed to the right by the baffle 320. When the guide post 412 slides to the right end of the guide groove 233, the arc segment will just separate from the baffle 320. Under the rebound action of the spring 420, the support roller sleeve 410 will reset and engage with the feeding frame 430 to form a support for the auxiliary measuring wheel 230.

[0064] Furthermore, straight plates are welded to the upper and lower surfaces of the baffle plate 510, and the lower straight plate can slide in contact with the baffle plate 320 during the process of moving to the right and flipping down; such as Figure 4 As shown, when the vulcanized capsules that have been tested move to the right end of the conveyor belt 300, the baffle 320 will first contact the straight plate below the baffle plate 510 and push the baffle plate 510 until the baffle 320 passes the bend and separates from the baffle plate 510. Then, the vulcanized capsules will roll out of the conveyor belt 300 along the gap between the auxiliary test wheel 230 and the baffle plate 510 and the feed plate 120 and be collected.

[0065] Specifically, such as Figure 11 and Figure 14 As shown, a sliding rod 520 is inserted into the center of the baffle plate 510 and sleeved on the top of the unloading frame 540 to support the axial movement of the baffle plate 510; a limiting ring 550 is sleeved in the middle of the sliding rod 520, and a compression spring 530 is located between the limiting ring 550 and the unloading frame 540; a guide frame 130 is welded below the top surface of the right end of the frame 100; a pair of guide rods 560 are inserted into the top of the limiting ring 550, passing through the guide frame 130 and the straight plate above the baffle plate 510 from right to left.

[0066] The guide rod 560 is slidably sleeved with the guide frame 130, while it is tightly inserted with the straight plate above the baffle plate 510 and the limiting ring 550. The pair of guide rods 560 and the guide frame 130 are used to prevent the baffle plate 510 from rotating. The compression spring 530 rebounds the limiting ring 550 to drive the baffle plate 510 to reset and connect with the right end of the auxiliary measuring wheel 230 to form a support.

[0067] When the symmetrical detection device for vulcanized capsules of the present invention is used for detection, the servo motor 330 is started to drive the conveyor belt 300 to circulate. When the baffle 320 is rotated to its left end, the baffle 320, which is flipped up and moved to the right, contacts the arc segment of the linkage rod 411, and pushes the roller sleeve 410 into the connecting column 232, thereby opening the break with the feeding frame 430 so that the vulcanized capsule can be placed at the left end of the conveyor belt 300 and lean against the baffle 320. Under the rebound action of the spring 420, the roller sleeve 410 is reset and sleeved with the feeding frame 430 to form a support for the auxiliary measuring wheel 230.

[0068] When the vulcanizing capsule is transported to the outside of the auxiliary measuring wheel 230, the servo motor 330 stops working, and then the stepper motor 220 is started to drive the main measuring wheel 210 to rotate one revolution, which can roll the vulcanizing capsule on the auxiliary measuring wheel 230 to rotate one revolution. The industrial camera 110 then captures the trajectory of the vulcanizing capsule's edge spreading, and compares it with a standard image to determine the size of the error.

[0069] After the test is completed, the servo motor 330 continues to drive the conveyor belt 300 to move until the vulcanizing capsule moves to the right end of the conveyor belt. At this time, the baffle 320 will first contact the straight plate below the baffle plate 510 and push the baffle plate 510. Before the baffle 320 separates from the baffle plate 510 after the bend, the vulcanizing capsule rolls out of the conveyor belt 300 along the gap between the auxiliary test wheel 230 and the baffle plate 510 and the feed plate 120 and is collected. At this time, another baffle 320 also moves to the left end of the conveyor belt 300 at the bend. The staff continues to put in the vulcanizing capsule according to the above operation, thus forming a continuous flow test process.

[0070] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention.
