Description

Technical Field

[0001] This invention relates to the field of spinneret inspection technology, and in particular to an inspection device for spinnerets. Background Technology

[0002] As a core component of chemical fiber spinning machines, the spinneret is an indispensable key link in the spinning production process. Precise testing of its orifice size, orifice wall smoothness, and orifice shape regularity is crucial to confirm whether it meets the preset quality standards.

[0003] However, in actual industrial production, the structure of spinnerets is diverse. To adapt to specific spinning process requirements, some spinnerets have oblique holes arranged at an angle instead of conventional straight holes. Since the axis of the oblique holes forms a certain angle with the surface of the spinneret, the image acquisition device of the existing detection equipment is limited by the shooting angle and it is difficult to detect the oblique holes. This can easily lead to blind spots in the detection, resulting in the inability to detect quality defects of the oblique holes in a timely manner and affecting the accuracy of the detection.

[0004] To address the aforementioned technical challenge of inconvenient oblique hole detection, patent application number 202211221419.0 discloses a fiber spinneret detection device with a synchronous rotation drive mechanism. This detection device can adjust the tilt posture of the image acquisition device according to the tilt angle of the oblique hole on the spinneret, so that the acquisition lens maintains a corresponding angle with the axis of the oblique hole, effectively eliminating the blind zone of oblique hole detection and improving the accuracy of detection.

[0005] Although the aforementioned equipment incorporates an adjustable structure for the image acquisition device, it still has limitations. For example, it cannot simultaneously inspect both sides of the spinneret. Both the top and bottom surfaces of the spinneret have spinneret holes, and both sides' holes must meet preset quality standards before use. However, this equipment can only inspect a single surface of the spinneret. After completing the single-sided inspection, the operator must manually remove the spinneret from the worktable, flip it over, and reposition it, restarting the inspection process. This flipping and re-clamping process is cumbersome and time-consuming, directly impacting inspection efficiency. Summary of the Invention

[0006] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution that can solve the above problems.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1-12 In this embodiment of the invention, a testing device for spinnerets includes a housing 1, a testing mechanism 2, and a conveying mechanism 3.

[0043] The housing 1 is provided with a support platform 11. The beginning end of the support platform 11 extends out of the housing 1. The support platform 11 is provided with a feeding station, a testing station and a testing station in sequence along the longitudinal direction. An opening 12 is provided on the testing station.

[0044] There are two sets of detection mechanisms 2. The two sets of detection mechanisms 2 are set inside the housing 1 and are located above and below the detection station, respectively. Both sets of detection mechanisms 2 include a first drive assembly 21. The drive end of the first drive assembly 21 is provided with a working arm. The working arm is composed of a first arm body 22 and a second arm body 23 that are hinged together. The second arm body 23 always tends to move closer to the first arm body 22 and intersect with its axis. The first arm body 22 is provided with a second drive assembly 26. The drive end of the second drive assembly 26 is connected to the second arm body 23 to drive the second arm body 23 to move in a fan shape. The end of the second arm body 23 is provided with an image acquisition device 25.

[0045] The conveying mechanism 3 is mounted on the support platform 11. The conveying mechanism 3 includes a conveying platform 31, which can move longitudinally between the loading station, the testing station, and the testing station. The conveying platform 31 has a testing port 334 that runs through its top and bottom surfaces. A flipping plate 335 is hinged inside the testing port 334. Two clamping blocks 336 are arranged at lateral intervals on the top surface of the conveying platform 31. When the conveying platform 31 moves from the loading station to the testing station, the two clamping blocks 336 move closer to each other. When the conveying platform 31 moves from the testing station to the loading station, the two clamping blocks 336 move further apart. When the conveying platform 31 moves from the testing station to the testing station, the flipping plate 335 flips downward to open the testing port 334. When the conveying platform 31 moves from the testing station to the testing station, the flipping plate 335 flips upward to close the testing port 334.

[0046] In use, the conveyor table 31 is in the loading station. After the operator places the spinneret on the flip plate 335, the conveyor table 31 moves longitudinally to the inspection station. During this process, the two clamping blocks 336 move closer to each other to clamp and fix the spinneret. Then the conveyor table 31 continues to move to the inspection station, and the flip plate 335 flips downward to open the inspection port 334, exposing the bottom surface of the spinneret to the inspection mechanism 2 below. At this time, the two sets of inspection mechanisms 2 located on the upper and lower sides of the inspection station can simultaneously collect images of each hole on the spinneret. By comparing the collected images with the preset template information, it can be determined whether each hole on both sides of the spinneret meets the preset requirements, thereby improving the inspection efficiency.

[0047] During the inspection process, the image acquisition device 25 can move horizontally, vertically and longitudinally under the drive of the first drive component, so as to realize comprehensive inspection of different positions of the spinneret and expand the inspection range. At the same time, under the drive of the second drive component 26, the second arm 23 and the image acquisition device 25 can move in a fan shape, which makes it easier for the image acquisition device 25 to inspect the hole positions of oblique holes, protrusions or depressions, avoid inspection omissions, and ensure the spinning quality.

[0048] After the inspection is completed, the conveyor 31 returns longitudinally to the loading station. When the conveyor 31 moves to the inspection station, the flip plate 335 flips upward to be flush with the surface of the conveyor 31, closing the inspection port 334 and thus supporting the spinneret. When the conveyor 31 returns to the loading station, the two clamps 336 move away from each other, releasing the clamps on the spinneret and making it easier for the staff to remove the spinneret.

[0049] The first drive assembly 21 includes two support frames 27, which are respectively disposed on the inner walls of the two sides of the housing 1. One support frame 27 is equipped with a first electric slide 28, and the other support frame 27 is equipped with a slider 29. A longitudinal transfer plate 210 is provided between the drive end of the first electric slide 28 and the slider 29. A second electric slide 211 is provided on the longitudinal transfer plate 210. A transverse transfer frame 24 is provided on the drive end of the second electric slide 211. A third electric slide 212 is provided on the transverse transfer frame 24. A lifting frame 213 is provided on the drive end of the third electric slide 212. During the detection process, the image acquisition unit 25 is driven to move horizontally, vertically, and longitudinally through the coordinated operation of the first electric slide 28, the second electric slide 211, and the third electric slide 212.

[0050] The lifting frame 213 includes a frame plate 236, which is connected to the drive end of the third electric slide 212. Two side plates 214 are vertically spaced along the frame plate 236, each with a through hole. The first arm 22 passes through these two through holes. One side plate 214 has a vertical piece 215 with a collar 216. A fixing groove 217 is formed on the surface of the first arm 22 near its upper end, extending circumferentially along the first arm 22. The collar 216 is fitted onto the fixing groove. Inside the fixed groove 217, a driven wheel 218 is fitted on the first arm body 22. The driven wheel 218 is located between two side plates 214. A keyway 219 is opened on the surface of the first arm body 22. The keyway 219 extends along the axial direction of the first arm body 22. The inner wall of the driven wheel 218 is provided with key teeth 220, which are located in the keyway 219. A first motor 221 is provided on the other side plate 214. A drive wheel 222 is provided on the drive end of the first motor 221. A transmission belt 223 is fitted over the drive wheel 222 and the driven wheel 218. It should be noted that the first arm body 22 and the driven wheel 218 can achieve stable torque transmission through the cooperation of the key teeth 220 and the keyway 219. During the detection process, the first motor 221 drives the connected drive wheel 222 to rotate. Through the power transmission belt 223, the driven wheel 218 rotates synchronously. With the circumferential limiting effect of the key teeth 220 and the keyway 219, the rotational torque of the driven wheel 218 is transmitted to the first arm body 22, driving the first arm body 22 to rotate around its own axis, thereby driving the working arm and the image acquisition device 25 to rotate and expand the image acquisition range.

[0051] The lower end face of the first arm 22 has two first hinge blocks 224 spaced longitudinally, and the upper end face of the second arm 23 has two second hinge blocks 225 spaced longitudinally. A rotating shaft 226 passes through each first hinge block 224 and the corresponding second hinge block 225. The second drive assembly 26 includes two mounting shells 228, which are symmetrically arranged laterally on both sides of the first arm 22. The lower end face of the first arm 22 has two wire holes 227, which communicate with the two mounting shells 228 respectively. A second motor 229 is provided inside the 228. A spool 230 is provided on the drive end of the second motor 229. A first pull wire 231 is wound around the spool 230. The beginning end of the first pull wire 231 is fixedly connected to the surface of the spool 230. The end of the first pull wire 231 passes through one of the wire holes 227 and is connected to the upper end face of the second arm body 23. A second pull wire 232 is provided inside another mounting shell 228. A tension spring 233 is connected between the beginning end of the second pull wire 232 and the inner wall of the mounting shell 228. The end of the second pull wire 232 passes through another wire hole 227 and is connected to the upper end face of the second arm body 23. It should be noted that, under the action of the tension spring 233, the second pull wire 232 pulls the second arm 23, so that the second arm 23 always tends to intersect with the first arm 22, thereby ensuring that the image acquisition device 25 can effectively detect the hole positions of the protrusions or depressions on the surface of the workpiece; when it is necessary to change the image acquisition angle, the second motor 229 drives the pulley 230 to rotate, and the first pull wire 231 drives the second arm 23 to swing in a fan shape to adjust the shooting angle of the image acquisition device 25 and further expand the detection range.

[0052] The conveyor table 31 includes two longitudinally spaced support plates 32, and two transversely spaced support shafts 33 between the two support plates 32. The two support plates 32 and the two support shafts 33 enclose a detection port 334. There are two flip plates 335, and the bottom surface of each flip plate 335 is provided with a bearing 34. The two bearings 34 are respectively sleeved on the two support shafts 33. The support table 11 is provided with two slide rails 338, which extend longitudinally and are spaced laterally. Support plates 35 are slidably arranged on each of the two slide rails 338. The two ends of the support plates 32 are respectively connected to the two support plates 35. A third motor 36 is provided on one of the support plates 35. A gear 37 is provided on the drive end of the third motor 36. A rack 38 is provided on the side of one of the slide rails 338. The gear 37 meshes with the rack 38. During operation, the tilting plate 335 is used to support the spinneret. The third motor 36 drives the gear 37 to rotate. Under the meshing transmission of the gear 37 and the rack 38, the tilting plate 335 and the spinneret move longitudinally between the feeding station, the inspection station and the inspection station.

[0053] A first movable block 337 is slidably disposed on the inner side of the support plate 35. A groove 39 penetrating the top and bottom surfaces of the bearing plate 32 is provided. A connecting block 310 is slidably disposed in the groove 39. A clamping block 336 is connected to the connecting block 310. A first connecting rod 311 is hinged between the first movable block 337 and the connecting block 310. A first movable rod 312 is provided at the bottom of the first movable block 337. A first guide rail 313 is provided longitudinally on the bearing platform 11. The lower end of the first movable rod 312 is slidably engaged with the top surface of the first guide rail 313. A first plane 31 is provided on the top surface of the first guide rail 313 along its length direction. 4. The first inclined surface 315 and the second plane 316 are located between the loading station and the inspection station. The inner side of the support plate 35 is provided with a first mounting block 317 above the first movable block 337. The bottom surface of the first mounting block 317 is provided with a first guide rod 318. The first movable block 337 is provided with a first guide hole for the first guide rod 318 to extend into. The first guide rod 318 is fitted with a first spring 319. One end of the first spring 319 abuts against the first mounting block 317, and the other end of the first spring 319 abuts against the first movable block 337. When the conveyor 31 carrying the spinneret moves from the loading station to the inspection station, the first movable rod 312 contacts the second plane 316, driving the first movable block 337 to move upward; under the transmission action of the first connecting rod 311, the connecting block 310 and the clamping block 336 move toward the spinneret, ultimately achieving the clamping and fixing of the spinneret.

[0054] A second movable block 320 is slidably disposed on the outer side of the support plate 35. An extension 321 is provided on the end of the flip plate 335 away from the detection port 334. A second connecting rod 322 is hinged between the second movable block 320 and the extension 321. A second movable rod 323 is provided on the bottom surface of the second movable block 320. A second guide rail 324 is arranged longitudinally on the support platform 11. The lower end of the second movable rod 323 is slidably engaged with the top surface of the second guide rail 324. A third plane 325, a second inclined plane 326, and a fourth plane 326 are provided on the top surface of the second guide rail 324 along its length. 27. The fourth plane 327 is higher than the third plane 325. The second inclined plane 326 is located between the station to be inspected and the inspection station. The outer side of the support plate 35, above the second movable block 320, is provided with a second mounting block 328. The bottom surface of the second mounting block 328 is provided with a second guide rod 329. The second movable block 320 has a second guide hole for the second guide rod 329 to extend into. A second spring 330 is sleeved on the second guide rod 329. One end of the second spring 330 abuts against the second mounting block 328, and the other end of the second spring 330 abuts against the second movable block 320. When the conveyor table 31 carrying the spinneret moves from the station to be inspected to the inspection station, the second movable rod 323 contacts the fourth plane 327, driving the second movable block 320 to move upward. Under the transmission action of the second connecting rod 322, the flipping plate 335 is driven to flip downward, thereby opening the inspection port 334, providing conditions for subsequent inspection processes.

[0055] It should be noted that when the conveyor 31 carrying the spinneret moves from the inspection station to the loading station, under the action of the first spring 319 and the second spring 330, the first movable rod 312 and the second movable rod 323 slide down along the first inclined plane 315 and the second inclined plane 326 to the first plane 314 and the second plane 316 respectively, driving the first movable block 337 and the second movable block 320 to move downward, thereby successively driving the flipping plate 335 to flip upward to be flush with the bearing plate 32 to support the spinneret, and driving the clamping block 336 away from the spinneret.

[0056] To make the connecting block 310 move more stably, the bottom surface of the bearing plate 32 is provided with third mounting blocks 331 spaced laterally, and a third guide rod 332 is provided between two third mounting blocks 331.
