[0004] Therefore, we provide a kind of expansion raw material belt finished product detection's damage detection device to solve the above problems. UTILITY MODEL CONTENTS
[0005] The utility model aims at providing a kind of expansion raw material belt finished product detection's damage detection device, solve the problem raised in the above background.
[0006] The application provides a kind of expansion green tape finished product detection broken detection device, including detection frame and expansion green tape broken detection component, the inner side of the detection frame is equipped with driven feed roller, the expansion green tape broken detection component includes the support driven roller that is arranged in the middle of the inner side of detection frame, the middle position of the support driven roller is provided with laser tape transmitter, the upper side of the laser tape transmitter is equipped with laser tape light sensor, the right side of the laser tape light sensor is equipped with visual scanning camera, the front side of the laser tape transmitter is provided with data control panel, the right side of the detection frame is provided with green tape winding assembly.

[0009] Preferably, the visual scanning camera is vertically arranged with the right support driven roller, and the visual scanning camera and the data control panel are electrically connected.

[0012] Preferably, the end of the extrusion spring is welded to the inner side of the spring bin, and the extrusion spring is welded to the driven clamping shaft.
[0013] As can be seen from the above technical solution, this application provides a damage detection device for finished expanded PTFE tape. In use, a new take-up ring is first inserted into two sets of take-up ring clamps. At this time, the compression spring in the spring chamber will push the driven clamping shaft to clamp the take-up ring. Then, the expanded PTFE tape is placed on the detection frame, and the very end of the expanded PTFE tape is wound into the take-up ring. Subsequently, the take-up motor drives the take-up drive shaft to rotate along the take-up drive support bearing in the take-up power support frame, and drives the driven clamping shaft along the inner side of the take-up driven support bearing at the end of the take-up driven support frame. The inner ring of the bearing rotates passively. As it is wound up, a driven feeding roller provides support and transmission. The expanded raw material tape is then wound into the winding ring under the tension of the driven support roller. During this process, the laser strip emitter on the lower side of the expanded raw material tape emits a laser. When the expanded raw material tape has a hole, the laser beam will pass through the hole and be scanned by the laser strip light sensor. Then, after visual scanning by a vision scanning camera, the data is transmitted to the data control panel for analysis to check for damage and uneven material distribution. This completes the use of a damage detection device for finished expanded raw material tape.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. When needed, the two sets of support rollers can support the expanded PTFE tape to be inspected, allowing for a flat support state and better detection of damage from both top and bottom. This also helps to keep the expanded PTFE tape taut. The expanded PTFE tape passing through the support rollers is then subjected to laser beams emitted from the laser strip emitter from bottom to top. During this process, if there are any leaks in the expanded PTFE tape, the laser beam will penetrate through these leaks and enter the laser strip light sensor for illumination and signal collection. This allows for targeted collection of information on the location and extent of damage. Since the expanded PTFE tape has a uniform color, mostly milky white, a visual scanning camera will then visually scan the color of the expanded PTFE tape to detect whether the material is uniform and whether it contains impurities.
[0016] 2. The winding motor outside the winding power support frame drives the winding drive shaft and the winding drive support bearing, thereby rotating the winding ring clamp plate at the end of the winding drive shaft and the winding ring clamp plate at the end of the driven clamp shaft. This allows the expanded raw material tape to be wound into the winding ring for tight collection. The driven clamp shaft and the winding driven support bearing, installed on the inner side of the bearing inner wall ring, work with the winding motor to perform the collection operation, making the rotation of the winding ring more stable during the winding process and preventing dislocation due to different speeds on both sides. It can also push the driven clamp shaft, causing the compression spring at the end of the driven clamp shaft to be squeezed into the spring chamber, facilitating the replacement of the winding ring. During this process, the rotation of the driven clamp shaft will drive the spring chamber through the compression spring, and the spring chamber will drive the inner wall ring of the bearing to rotate, thus achieving the effect of driven rotation in conjunction with the winding driven support bearing.
[0017] In summary, this application can detect the damage degree of the grown raw material tape by detecting the minute leakage holes and uniformity of the finished product after the production of the expanded raw material tape. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0025] See Figures 1-5 A damage detection device for finished expanded raw material tape includes a detection frame 1 and an expanded raw material tape damage detection component 3. Driven feeding rollers 2 are installed on the inner side of the detection frame 1. The expanded raw material tape damage detection component 3 includes a supporting driven roller 301, which is located in the middle of the inner side of the detection frame 1. A laser tape emitter 302 is located in the middle of the supporting driven roller 301. A laser tape light sensor 303 is installed on the upper side of the laser tape emitter 302. A visual scanning camera 304 is installed on the right side of the laser tape light sensor 303. A data control panel 305 is located on the front side of the laser tape emitter 302. A raw material tape winding component 4 is located on the right side of the detection frame 1.
[0026] In this invention, the supporting driven rollers 301 are arranged symmetrically in two groups on the left and right. The height of the supporting driven rollers 301 is higher than the height of the driven feeding rollers 2. When needed, the two groups of supporting driven rollers 301 can support the expanded raw material belt to be tested, so as to present a flat support state, thereby better detecting damage from the top and bottom, and can make the expanded raw material belt as taut as possible.
[0027] In this invention, the laser strip emitter 302 and the laser strip light sensor 303 are electrically connected and are arranged symmetrically vertically. When needed, the expanded raw material strip supported by the driven roller 301 will be emitted with laser light from bottom to top by the laser strip emitter 302. During this process, if the expanded raw material strip has leakage holes, the laser light will penetrate through the leakage holes and enter the laser strip light sensor 303 for irradiation and laser signal collection. This allows for targeted collection of the location and degree of damage.
[0028] In this invention, the visual scanning camera 304 is positioned perpendicular to the right-side support driven roller 301. The visual scanning camera 304 is electrically connected to the data control panel 305. When needed, since the overall color of the expanded raw material tape is uniform and mostly milky white, the visual scanning camera 304 will visually scan the color of the expanded raw material tape to detect whether the material of the expanded raw material tape is uniform and whether it contains impurities.
[0029] In this utility model, the raw material tape winding assembly 4 includes a winding power support frame 401 welded to the front right side of the inspection frame 1. A winding active support bearing 402 is installed at the middle of the end of the winding power support frame 401. A winding active support bearing 403 is welded to the middle of the winding active support bearing 402. A winding motor 404 is connected to the left side of the winding active support bearing 403. A winding ring clamp 405 is welded to the right side of the winding active support bearing 403. A winding driven support frame 406 is welded to the rear right side of the inspection frame 1. A winding driven support bearing 407 is installed at the middle of the end of the winding driven support frame 406. The inner side of 7 is provided with a bearing inner wall ring 408, and a spring chamber 409 is welded to the right side of the bearing inner wall ring 408. A compression spring 410 is provided inside the spring chamber 409, and a driven clamping shaft 411 is provided inside the bearing inner wall ring 408. When needed, the winding motor 404 outside the winding power support frame 401 drives the winding drive shaft 403 and the winding drive support bearing 402 to rotate the winding ring clamp 405 clamped at the end of the winding drive shaft 403 and the winding ring clamp 405 clamped at the end of the driven clamping shaft 411, so that the expanded raw material tape is wound into the winding ring for tight collection.
[0030] In this invention, the inner wall ring 408 of the bearing and the winding driven support bearing 407 are rotatably connected, and the inner wall ring 408 of the bearing and the winding driven support bearing 407 are tightly fitted together. The driven clamping shaft 411 and the winding driven support bearing 407 form a rotating structure through the inner wall ring 408 of the bearing. When needed, the driven clamping shaft 411 and the winding driven support bearing 407 installed on the inner side of the inner wall ring 408 cooperate with the winding motor 404 to perform the collection operation, thereby making the rotation of the winding ring more stable during the winding process and avoiding the occurrence of dislocation due to the different speeds on both sides.
[0031] In this invention, the end of the compression spring 410 is welded to the inner side of the spring chamber 409, and the compression spring 410 is welded to the driven clamping shaft 411. When needed, the driven clamping shaft 411 can be pushed, so that the compression spring 410 at the end of the driven clamping shaft 411 is squeezed into the spring chamber 409, which facilitates the replacement of the winding ring. During this process, the rotation of the driven clamping shaft 411 will drive the spring chamber 409 through the compression spring 410, and the spring chamber 409 will drive the inner wall ring 408 of the bearing to rotate, which, together with the winding driven support bearing 407, achieves the effect of driven rotation.
[0032] As can be seen from the above technical solution, in use, a new take-up ring is first inserted into the two sets of take-up ring clamping plates 405. At this time, the compression spring 410 in the spring chamber 409 will push the driven clamping shaft 411 to clamp the take-up ring. Then, the expanded PTFE tape is placed on the inspection frame 1, and the very end of the expanded PTFE tape is wound into the take-up ring. Subsequently, the take-up motor 404 drives the take-up drive shaft 403 to rotate along the take-up drive support bearing 402 in the take-up power support frame 401, and drives the driven clamping shaft 411 along the end of the take-up driven support frame 406 and along the inner side of the take-up driven support bearing 407. The wall ring 408 rotates passively, and as it is wound up, the passive feeding roller 2 provides support and transmission. Subsequently, the expanded raw material tape is wound into the winding ring under the tension of the support passive roller 301. During this process, the laser tape emitter 302 on the lower side of the expanded raw material tape emits a laser. When the expanded raw material tape has a hole, the laser beam will pass through the hole and be scanned by the laser tape light sensor 303. Then, after visual scanning by the visual scanning camera 304, the data is transmitted to the data control panel 305 for analysis to check for damage and uneven material. This completes the use of a damage detection device for finished expanded raw material tape.
