Description

Technical Field

[0001] The present application relates to the field of puncture detection technology, and in particular to a puncture detection method and device for producing puncture-resistant films. Background Art

[0002] Film is a thin, soft, transparent sheet made of plastic, adhesive, rubber or other materials. The scientific explanation of film is: a two-dimensional material formed by atoms, molecules or ions deposited on the surface of a substrate, such as optical films, composite films, superconducting films, puncture-resistant films and plastic films. Film materials refer to thin metal or organic layers with a thickness ranging from a single atom to several millimeters. Electronic semiconductor functional devices and optical coatings are the main applications of thin film technology.

[0003] After the film is produced, it is necessary to conduct quality inspection on the film, mainly to test the thickness, puncture resistance and tensile capacity of the film. The puncture resistance test of the film is mainly completed by puncture testing equipment. The existing puncture resistance testing instrument mainly uses a clamp to clamp the film to be tested, and then applies downward pressure to the film through the puncture needle, and uses a pressure sensor to monitor the pressure on the film. When the film is penetrated by the puncture needle, the pressure applied by the puncture needle will be transmitted to the display screen through an electrical signal to obtain the puncture resistance pressure value of the puncture-resistant film. In this process, since the film is clamped by the clamp, it will be subjected to a certain pulling force, which will cause wrinkles in the middle of the puncture-resistant film, and the part that the puncture needle is to pass through is exactly in the middle of the puncture-resistant film. At this time, the wrinkles will affect the pressure-bearing capacity of the puncture-resistant film, resulting in deviations in the detected values, affecting the accuracy of the detection effect. Secondly, the puncture-resistant film needs to be subjected to tensile testing after the puncture test. At this time, the equipment needs to be replaced, which makes the detection process more complicated. Summary of the invention

[0033] A method for using a puncture detection device for producing a puncture-resistant film comprises the following steps:

[0034] In the first step, the puncture-resistant film is passed through the through slot on the left wall of the clamp seat, the rectangular slot and the through slot on the right wall of the clamp seat in sequence, and then the handle is used to rotate the adjusting screw, so that the sliding block moves up and down in the sliding slot through the rotation of the adjusting screw, thereby fixing the puncture-resistant film with the sliding block and the fixing block;

[0035] In the second step, after the puncture-resistant film is fixed, the movable block is manually pulled to slide on the guide rod, so that the movable block moves synchronously with the movable plate, and then the tension spring is used to make the movable plate close to the upper surface of the puncture-resistant film, so that the movable plate can smooth the wrinkles on the puncture-resistant film during the movement;

[0036] The third step is to turn on the hydraulic cylinder, which drives the hydraulic rod to extend downward. The hydraulic rod moves downward with the pressure detection device and the puncture needle, and uses the puncture needle to perform puncture detection on the puncture-resistant film. At this time, the pressure generated when the puncture-resistant film contacts the puncture needle will prompt the puncture needle to move upward, and the puncture needle moves upward with the pressure plate, and the pressure plate is used to apply pressure to the pressure sensor, so that the pressure sensed by the pressure sensor is transmitted to the display screen through an electrical signal and displayed on the display screen. The staff can know the detection result of the puncture-resistant film through the value on the display screen;

[0037] In the fourth step, when the puncture-resistant film is subjected to puncture detection, the pressure detection device is moved downward by the hydraulic rod, so that the pressure detection device will move downward with the side plate, and the side plate will squeeze the airbag, so that the gas inside the airbag enters the connecting pipe after being squeezed, and then is transmitted to the sleeve through the connecting pipe, so that the air pressure inside the sleeve is increased, and the piston plate is pushed downward by the air pressure, so that the piston plate will move downward with the connecting rod and the movable plate, so that the movable plate is attached to the upper surface of the puncture-resistant film, and the puncture-resistant film is tightened, so as to further prevent wrinkles from appearing on the puncture-resistant film;

[0038] Step 5. When the puncture-resistant film needs to be tested for tension, one end of the puncture-resistant film is fixed by a fixed block and a sliding block, and then the position of the movable block is adjusted, and the other end of the puncture-resistant film is placed in the rectangular groove. At this time, the electromagnetic block is energized to obtain magnetism, and the movable plate is adsorbed by the electromagnetic block, so that the electromagnetic block and the movable plate can fix the puncture-resistant film. Then, the movable block is pulled to slide on the guide rod, so that the tension borne by the puncture-resistant film is applied to the tension sensor through the pull rope, and the tension sensed by the tension sensor is transmitted to the display screen through an electrical signal and displayed on the display screen, thereby completing the tension test of the puncture-resistant film without changing the equipment.

[0039] Step 6. When the puncture-resistant film needs to be tested at different positions, first loosen the threaded rod to allow the movable block to slide on the guide rod to adjust its position. After the position of the movable block is adjusted, tighten the threaded rod to limit the position of the movable block. Then, fix one end of the puncture-resistant film by a fixed block and a sliding block, and fix the other end of the puncture-resistant film by an electromagnetic block and a movable plate. Then, turn on the hydraulic cylinder to drive the pressure detection device and the puncture needle to move downward to complete the puncture-resistant detection of the puncture-resistant film at different positions.

[0040] The present application provides a puncture detection method and device for puncture-resistant film production. By designing a guide rod, a movable block, a rectangular groove, a movable plate, a connecting rod, a piston plate and a tension spring, when the puncture-resistant film passes through the through groove on the clamp seat and is clamped by the fixed block and the sliding block, the movable block is pulled to slide on the guide rod so that the movable plate in the movable block will abut against the puncture-resistant film. At this time, the movable plate will move synchronously with the movable block, and then the puncture-resistant film will be smoothed by the movable plate to prevent the puncture-resistant film from being wrinkled after being clamped, which will affect the data of the puncture-resistant detection.

[0041] When the puncture-resistant film needs to be tested for tension, the puncture-resistant film is first passed through the through slot on the clamp seat, and then through the rectangular slot on the movable block. At this time, the electromagnetic block is energized to obtain magnetism, so that the electromagnetic block will adsorb the movable plate, and the movable plate and the electromagnetic block will clamp the puncture-resistant film. Then the movable block is pulled to move on the guide rod, so that the tension sensor on the movable block will cooperate with the pull rope, causing the tension borne by the puncture-resistant film to be transmitted to the display screen by the tension sensor through an electrical signal for display, thereby completing the tension test of the puncture-resistant film without changing the equipment for testing, thereby improving the convenience of testing.

[0042] At the same time, when the puncture needle moves downward to perform puncture detection on the puncture-resistant membrane, as the pressure detection device moves downward, the pressure detection device will drive the side plate to move downward synchronously. At this time, the side plate will squeeze the airbag, so that the gas inside the airbag enters the interior of the connecting tube due to the squeezing, and utilizes the transmission of the connecting tube to make the gas inside the airbag finally enter the sleeve, thereby increasing the air pressure inside the sleeve, causing the piston plate to move downward under the action of the air pressure, so that the piston plate will move downward with the connecting rod and the movable plate, so that the movable plate abuts against the puncture-resistant membrane, causing the puncture-resistant membrane to be tightened, further preventing wrinkles on the puncture-resistant membrane, and improving the accuracy of the puncture-resistant membrane during puncture detection.

[0043] Secondly, when the puncture-resistant film needs to be tested for puncture resistance at different positions, one end of the puncture-resistant film is clamped by the fixed block and the sliding block, and then the position of the movable block on the guide rod is adjusted. After the position adjustment of the movable block is completed, the threaded rod is tightened to limit the position of the movable block. At this time, the other end of the puncture-resistant film is fixed by adsorbing the movable plate through the electromagnetic block, and then the hydraulic cylinder is turned on to make the hydraulic rod move down with the puncture needle to realize the puncture detection of the puncture-resistant film. The above structure can realize the puncture resistance detection of the puncture-resistant film at different positions, improve the effect of the puncture detection of the puncture-resistant film, and the puncture resistance detection at different positions can provide different comparative data, thereby expanding the reference data of the puncture-resistant film.

[0062] A method for using a puncture detection device for producing a puncture-resistant film comprises the following steps:

[0063] In the first step, the puncture-resistant film is passed through the through slot 18 on the left side wall of the clamp seat 13, the rectangular slot 133 and the through slot 18 on the right side wall of the clamp seat 13 in sequence, and then the handle 20 is used to rotate the adjusting screw 19, so that the sliding block 17 moves up and down in the sliding slot 16 through the rotation of the adjusting screw 19, thereby fixing the puncture-resistant film by using the sliding block 17 and the fixing block 15;

[0064] In the second step, after the puncture-resistant film is fixed, the movable block 132 is manually pulled to slide on the guide rod 131, so that the movable block 132 moves synchronously with the movable plate 135, and then the tension spring 138 is used to make the movable plate 135 close to the upper surface of the puncture-resistant film, so that the movable plate 135 can smooth the wrinkles on the puncture-resistant film during the movement;

[0065] The third step is to turn on the hydraulic cylinder 5, which drives the hydraulic rod 6 to extend downward. The hydraulic rod 6 moves downward with the pressure detection device 7 and the puncture needle 11, and uses the puncture needle 11 to perform puncture detection on the puncture-resistant film. At this time, the pressure generated when the puncture-resistant film contacts the puncture needle 11 will prompt the puncture needle 11 to move upward, and the puncture needle 11 moves upward with the pressing plate 9. The pressing plate 9 applies pressure to the pressure sensor 8, so that the pressure sensed by the pressure sensor 8 is transmitted to the display screen 21 through an electrical signal and displayed on the display screen 21. The staff can know the detection result of the puncture-resistant film through the value on the display screen 21;

[0066] In the fourth step, when the puncture-resistant film is subjected to puncture detection, the pressure detection device 7 is moved downward by the hydraulic rod 6, so that the pressure detection device 7 will move downward with the side plate 71, and the side plate 71 will squeeze the airbag 32, so that the gas inside the airbag 32 enters the connecting pipe 33 after being squeezed, and then is transmitted to the sleeve 139 through the connecting pipe 33, so that the air pressure inside the sleeve 139 increases, and the air pressure is used to push the piston plate 137 downward, so that the piston plate 137 will move downward with the connecting rod 136 and the movable plate 135, so that the movable plate 135 is attached to the upper surface of the puncture-resistant film, and the puncture-resistant film is tightened, so as to further prevent wrinkles on the puncture-resistant film;

[0067] Step 5. When the puncture-resistant film needs to be tested for tension, one end of the puncture-resistant film is fixed by the fixed block 15 and the sliding block 17, and then the position of the movable block 132 is adjusted, and the other end of the puncture-resistant film is placed in the rectangular groove 133. At this time, the electromagnetic block 134 is controlled to be energized to obtain magnetism. At this time, the electromagnetic block 134 is used to adsorb the movable plate 135, so that the electromagnetic block 134 and the movable plate 135 can fix the puncture-resistant film. Then, the movable block 132 is pulled to slide on the guide rod 131, so that the tension borne by the puncture-resistant film is applied to the tension sensor 152 through the pull rope 151, and the tension sensed by the tension sensor 152 is transmitted to the display screen 21 through an electrical signal and displayed on the display screen 21, thereby completing the tension test of the puncture-resistant film without changing the equipment.

[0068] In the sixth step, when the puncture-resistant film needs to be tested at different positions, first loosen the threaded rod 141 to allow the movable block 132 to slide on the guide rod 131 to adjust the position. After the position of the movable block 132 is adjusted, tighten the threaded rod 141 to limit the position of the movable block 132. Then, one end of the puncture-resistant film is fixed by the fixed block 15 and the sliding block 17, and the other end of the puncture-resistant film is fixed by the electromagnetic block 134 and the movable plate 135. Then, the hydraulic cylinder 5 is turned on to drive the pressure detection device 7 and the puncture needle 11 to move downward to complete the puncture-resistant detection of the puncture-resistant film at different positions.

[0069] Working principle: when the puncture-resistant film needs to be punctured, the puncture-resistant film is passed through the left through slot 18, the rectangular slot 133 and the right through slot 18 in sequence, and then the handle 20 is turned, and the handle 20 drives the adjusting screw 19 to rotate, so that the sliding block 17 moves down along the sliding slot 16, so that the puncture-resistant film is clamped by the sliding block 17 and the fixed block 15, and then the hydraulic cylinder 5 is turned on, and the hydraulic cylinder 5 drives the hydraulic rod 6 to move down, and the hydraulic rod 6 moves down with the pressure detection device 7 and the puncture needle 11, and the puncture needle 11 is used to perform puncture resistance detection on the fixed puncture-resistant film, and the pressure generated after the puncture needle 11 contacts the puncture-resistant film will prompt the puncture needle 11 to move up, so that the puncture needle 11 moves up with the pressure plate 9, so that the pressure plate 9 acts on the pressure sensor 8, and the pressure sensor 8 After the pressure is sensed, it is transmitted to the display screen 21 through an electrical signal, and then the puncture pressure borne by the puncture-resistant film is displayed on the display screen 21. In this process, when the puncture-resistant film passes through the through slot 18 on the clamp seat 13 and is clamped by the fixed block 15 and the sliding block 17, the movable block 132 is pulled to slide on the guide rod 131, so that the movable plate 135 in the movable block 132 will abut against the puncture-resistant film. At this time, the movable plate 135 will move synchronously with the movable block 132, and then the movable movable plate 135 will be used to smooth the puncture-resistant film to prevent the puncture-resistant film from wrinkling after being clamped and affecting the data of the puncture-resistant test. When the puncture-resistant film needs to be tested for tension, the puncture-resistant film is first passed through the through slot 18 on the clamp seat 13, and then through the movable block 132. Rectangular groove 133, at this time, the electromagnetic block 134 is controlled to be energized to obtain magnetism, so that the electromagnetic block 134 will adsorb the movable plate 135, so that the movable plate 135 and the electromagnetic block 134 will clamp the puncture-resistant film, and then pull the movable block 132 to move on the guide rod 131, so that the tension sensor 152 on the movable block 132 will form a match with the pull rope 151, so that the tension borne by the puncture-resistant film will be transmitted to the display screen 21 by the tension sensor 152 through an electrical signal, thereby completing the tension detection of the puncture-resistant film, without the need to replace the detection equipment, which improves the convenience of detection. When the puncture needle 11 moves downward to perform puncture detection on the puncture-resistant film, as the pressure detection device 7 moves downward, the pressure detection device 7 will drive the side plate 71 to move downward synchronously. At this time, the side plate 71 will squeeze the airbag 32, so that the gas inside the airbag 32 enters the interior of the connecting tube 33 due to the squeezing, and the gas inside the airbag 32 finally enters the sleeve 139 through the transmission of the connecting tube 33, thereby increasing the air pressure inside the sleeve 139, causing the piston plate 137 to move downward under the action of the air pressure, so that the piston plate 137 will move downward with the connecting rod 136 and the movable plate 135, so that the movable plate 135 abuts against the puncture-resistant film, causing the puncture-resistant film to be tightened, further preventing wrinkles on the puncture-resistant film, and improving the accuracy of the puncture-resistant film during puncture detection. Secondly, when the puncture-resistant film needs to be tested for puncture resistance at different positions, one end of the puncture-resistant film is clamped by the fixed block 15 and the sliding block 17.Then adjust the position of the movable block 132 on the guide rod 131. When the position of the movable block 132 is adjusted, tighten the threaded rod 141 to limit the position of the movable block 132. At this time, the other end of the puncture-resistant film is fixed by adsorbing the movable plate 135 through the electromagnetic block 134. Then, the hydraulic cylinder 5 is turned on to make the hydraulic rod 6 move down with the puncture needle 11 to realize the puncture detection of the puncture-resistant film. The above structure can realize the puncture detection of the puncture-resistant film at different positions, improve the effect of the puncture detection of the puncture-resistant film, and the puncture detection at different positions can provide different comparative data, expanding the reference data of the puncture-resistant film.
