Description

Technical Field

[0001] The invention relates to the field of adhesive tape performance detection, and in particular to a device for detecting the temperature and pressure resistance of an insulating silicone tape during production. Background Art

[0002] After the tape is produced, it needs to be tested. Conventional tests include adhesive test and tensile test of the tape, and more special tapes also need to undergo different tests accordingly. For example, for insulating tape, due to the requirements of the use environment, it is necessary to ensure that the insulating tape has the characteristics of heat resistance and pressure resistance. Therefore, it is necessary to test the temperature resistance and pressure resistance of the insulating tape.

[0003] Chinese patent application CN117969407A discloses a tape viscosity testing device, including a test bench, and also includes: a placement plate, the placement plate is arranged at the bottom of the test bench, used to support the test bench, and a flat plate for receiving the test tape is arranged between the placement plate and the test bench; a tensioning placement unit, the tensioning placement unit is arranged on the placement plate, used to pull and move the tape to be tested and tension and fix the tape on one side of the test bench; the tensioning placement unit includes: a traction part, the traction part is arranged between the placement plate and the flat plate, used to pull and move the tape and tension and unfold it on one side of the test bench; a placement component, the placement component is arranged between the placement plate and the test bench, used to limit and fix the tape reel to rotate and unfold it; a moving component, the moving component is arranged on one side of the placement component, used to control the movement of the traction part and make the tape flat; a removal unit, the removal unit is arranged on both sides of the test bench, used to cut the tested tape and recycle it after cutting.

[0004] The above scheme realizes that the tape can be quickly unfolded when the adhesive tape is subjected to a viscosity test. In this way, the present invention mainly tests tapes with special functions, mainly insulating silicone tapes. As a type of insulating tape, the main performance of insulating silicone tape is temperature resistance and pressure resistance. The main testing method is relatively conventional. Here, the temperature resistance test is taken as an example. The traditional temperature resistance test usually takes a certain length of insulating silicone tape sample and places it in a heating furnace. The insulating silicone tape is heated by the heating furnace. Although the temperature resistance of the insulating silicone tape can be tested, it is worth noting that since one side of the tape has glue, the glue will melt after heating. Therefore, after the test is completed, the staff needs to manually remove the tape, which will cause the melted glue to stick to both hands, which is not conducive to experimental operation. In addition, when testing the temperature resistance of the tape, the usual operation is to take out the tape for observation after heating for a period of time. The heating temperature is usually high, and the tape needs to be placed for a period of time before being taken out. Therefore, the state of the tape just after heating cannot be directly observed. Summary of the invention

[0005] In view of the above problems, a device for detecting the temperature and pressure resistance of insulating silicone tape is provided, including a monitoring unit. A slide is also horizontally arranged in an outer shell, and the extension direction of the slide is perpendicular to the end face of the switch door in a closed state. The test bench is slidably arranged on the slide along the extension direction of the slide, and the slide is used to drive the test bench to move horizontally. When the test starts, the slide drives the test bench to the end close to the switch door, and then the staff sticks the insulating silicone tape on the test bench. The slide drives the test bench to move in the direction away from the switch door, and stops driving after the test bench reaches the end of the slide away from the switch door. Then the staff closes the switch door. At this time, the stopped test bench is located directly under the camera, and then the heating wire starts to heat the inside of the outer shell. The camera monitors the insulating silicone tape being heated. If the end of the camera is not provided with a glass insulation board at this time, the camera end needs to be in direct contact with the air in the outer shell. At this time, the air temperature in the outer shell is relatively high, so long-term use is easy to damage the camera. The internal components of the head are damaged, and the service life of the camera is shortened. After a glass insulation board is horizontally set at the camera end of the camera, the camera can be separated from the internal space of the shell, so that the high-temperature air in the shell will not directly contact the camera. However, when testing the insulating silicone tape, the insulating silicone tape needs to be insulated for a period of time, which will cause the temperature of the insulating cavity formed by the shell to gradually rise over time. This will still cause the camera to be damaged after a period of use. In this way, a cooling pipe is set in the isolation cavity, and a flowing coolant is provided in the cooling pipe. A circulation box is set at the end of the cooling pipe, and both ends of the cooling pipe are connected to the circulation box. Coolant is stored in the circulation box. The cooling pipe draws the coolant out of the circulation box, and then discharges the coolant after absorbing heat back into the circulation box. In this way, when testing the insulating silicone tape, the state changes of the insulating silicone tape after the temperature rises can be monitored in real time by the camera, and the high-temperature air in the shell will not affect the camera body.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention includes a monitoring unit, and a slide is horizontally arranged in the shell. The extension direction of the slide is perpendicular to the end face of the switch door in the closed state. The test bench is slidably arranged on the slide along the extension direction of the slide. The slide is used to drive the test bench to move horizontally. When the test starts, the slide drives the test bench to the end close to the switch door. Then the staff sticks the insulating silicone tape on the test bench. The slide drives the test bench to move in the direction away from the switch door, and stops driving after the test bench reaches the end of the slide away from the switch door. Then the staff closes the switch door. At this time, the stopped test bench is located directly under the camera. Then the heating wire starts to heat the inside of the shell. The camera monitors the insulating silicone tape being heated. If the end of the camera is not provided with a glass insulation board at this time, the camera end needs to be in direct contact with the air in the shell. At this time, the air temperature in the shell is relatively high. Such long-term use is easy to cause damage to the internal components of the camera. The use of the camera The service life is relatively low. After a glass insulation board is horizontally set at the camera end of the camera, the camera can be separated from the internal space of the shell, so that the high-temperature air in the shell will not directly contact the camera. However, when testing the insulating silicone tape, the insulating silicone tape needs to be insulated for a period of time. This will cause the temperature of the insulating cavity formed by the shell to gradually rise over time. This will still cause the camera to be damaged after a period of use. Therefore, a cooling pipe is set in the insulating cavity, and a flowing coolant is provided in the cooling pipe. A circulation box is set at the end of the cooling pipe. Both ends of the cooling pipe are connected to the circulation box. Coolant is stored in the circulation box. The cooling pipe draws the coolant out of the circulation box, and then discharges the coolant after absorbing heat back into the circulation box. In this way, when testing the insulating silicone tape, the state changes of the insulating silicone tape after the temperature rises can be monitored in real time by the camera, and the high-temperature air in the shell will not affect the camera body, thereby improving the accuracy of the detection result.

[0017] 2. By setting up a lifting rod and sheathing absorbent cotton on the outside of the lifting rod, direct contact between the lifting rod and the adhesive surface of the insulating silicone tape is avoided, and the insulating silicone tape is prevented from sticking to the lifting rod when the lifting rod lifts the insulating silicone tape up, resulting in the lifting rod being unable to be pulled out.

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Reference Figure 1-Figure 4 and Figure 6 : A temperature and pressure resistance detection device for insulating silicone tape during production, comprising an outer shell 1 and a laboratory table 2 arranged inside the outer shell 1, the laboratory table 2 is used to receive the insulating silicone tape 3; a monitoring unit 4 for monitoring the insulating silicone tape 3 located on the laboratory table 2 is arranged on the upper part of the outer shell 1, the monitoring unit 4 comprises a casing 43, the casing 43 is fixedly arranged on the upper part of the outer shell 1, an observation hole is arranged on the outer shell 1, a glass insulation board 42 is horizontally arranged on the observation hole, the glass insulation board 42 blocks the observation hole, the glass insulation board 42 is made of transparent material, and the upper and lower end surfaces of the glass insulation board 42 are parallel to the horizontal plane, a camera 41 is vertically arranged on the upper part of the casing 43, and the camera end of the camera 41 is vertically downward, the camera 41 is used to monitor the state of the insulating silicone tape 3, an isolation cavity is formed inside the casing 43, a cooling pipe 44 is arranged in the isolation cavity, and flowing coolant is stored in the cooling pipe 44, and when the camera 41 is in the monitoring state, the coolant in the cooling pipe 44 is in a flowing state.

[0035] A switch door 11 is hinged on the side of the shell 1, and a heating wire 13 is arranged on the inner wall of the shell 1. When the switch door 11 is closed, the heating wire 13 arranged inside the shell 1 is started, and the heating wire 13 heats the inside of the shell 1. In the existing temperature resistance test of the insulating silicone tape 3, the usual test process is to cut the insulating silicone tape 3 of a standard length, then stick the insulating silicone tape 3 on the test bench 2, and then put the test bench 2 into the shell 1. Since the shell 1 is provided with the heating wire 13, the heating wire 13 heats the environment in the shell 1 according to the preset temperature. When the heating wire 13 raises the temperature to the rated experimental temperature, the temperature is maintained for a period of time. The period of time needs to be preset according to the test requirements. When the temperature reaches the rated experimental temperature, the heating wire 13 is kept for a period of time. After the specified time, the heating wire 13 stops heating, and the heated insulating silicone tape 3 is taken out after cooling. However, this test method has a disadvantage, that is, it is necessary to cool down for a period of time after the test before the test bench 2 and the insulating silicone tape 3 set on the test bench 2 can be taken out, which is inefficient, and the insulating silicone tape 3 cannot be guaranteed to be exactly the same when it is just heated and after cooling. This will lead to deviations in the test results, and the heat resistance of the insulating silicone tape 3 cannot be accurately judged. In order to avoid the above problems, a monitoring unit 4 is set in the shell 1. The specific working principle is as follows: a slide 12 is horizontally arranged in the shell 1, and the extension direction of the slide 12 is perpendicular to the end face of the switch door 11 in the closed state, and the test bench 2 slides along the extension direction of the slide 12 The slide 12 is arranged on the test bench 2, and the slide 12 is used to drive the test bench 2 to move in the horizontal direction. When the test starts, the slide 12 drives the test bench 2 to the end close to the switch door 11, and then the staff puts the insulating silicone tape 3 on the test bench 2, and the slide 12 drives the test bench 2 to move in the direction away from the switch door 11, and stops driving after the test bench 2 reaches the end of the slide 12 away from the switch door 11, and then the staff closes the switch door 11. At this time, the stopped test bench 2 is located directly under the camera 41, and then the heating wire 13 starts to heat the inside of the shell 1, and the camera 41 monitors the insulating silicone tape 3 being heated. If the glass insulation board 42 is not provided at the end of the camera 41 at this time, the camera 41 will The end needs to be in direct contact with the air in the shell 1, and the air temperature in the shell 1 is relatively high at this time. Such long-term use may easily damage the internal components of the camera 41, and the service life of the camera 41 is relatively short. After a glass insulation board 42 is horizontally arranged at the camera end of the camera 41, the camera 41 can be separated from the internal space of the shell 1, so that the high-temperature air in the shell 1 will not directly contact the camera 41. However, when testing the insulating silicone tape 3, it is necessary to perform heat preservation measures on the insulating silicone tape 3 for a period of time, which will cause the temperature of the isolation cavity formed by the casing 43 to gradually increase over time. This will still cause the camera 41 to be damaged after being used for a period of time. Therefore, a cooling pipe 44 is arranged in the isolation cavity.A flowing coolant is provided in the cooling pipe 44, and a circulation box 45 is provided at the end of the cooling pipe 44. Both ends of the cooling pipe 44 are connected to the circulation box 45. The circulation box 45 contains coolant. The cooling pipe 44 extracts the coolant from the circulation box 45, and then discharges the coolant after absorbing heat back into the circulation box 45. In this way, when the insulating silicone belt 3 is tested, the state change of the insulating silicone belt 3 as the temperature rises can be monitored by the camera 41 in real time, and the high-temperature air in the housing 1 will not affect the camera 41 body.

[0036] Reference Fig.12 and Fig.13 : Two support blocks 21 are arranged on the experimental table 2 along the length direction of the experimental table 2, and the support blocks 21 are respectively located at both ends of the experimental table 2. An experimental groove 22 is vertically opened on the upper part of the support block 21, and a temperature sensor 23 is fixedly installed at the bottom of the experimental groove 22. The temperature sensor 23 is preset with a rated threshold value. When the insulating silicone tape 3 is placed on the experimental table 2, the two ends of the insulating silicone tape 3 are respectively attached to the upper part of the two support blocks 21, and the upper part of the experimental groove 22 is blocked.

[0037] When conducting the test, after cutting off a fixed length of the insulating silicone tape 3, the two ends of the cut insulating silicone tape 3 are respectively pasted on the upper part of the support block 21. After the insulating silicone tape 3 is pasted on the upper part of the support block 21, the experimental slot 22 on the upper part of the support block 21 is blocked. In this way, after the upper opening of the experimental slot 22 is pasted by the insulating silicone tape 3, a closed cavity is formed in the experimental slot 22, and the closed cavity is not in direct contact with the air in the outer shell 1. In this way, when the heating wire 13 in the outer shell 1 is started, the heating wire 13 can heat the air in the outer shell 1, and the temperature sensor 23 arranged at the bottom of the experimental slot 22 is started at the same time. After the test is completed, if the actual temperature monitored by the temperature sensor 23 is within the rated threshold, it means that the thermal insulation performance of the insulating silicone tape 3 meets the requirements. If the actual temperature monitored by the temperature sensor 23 exceeds the rated threshold, it means that the thermal insulation performance of the insulating silicone tape 3 does not meet the requirements.

[0038] Reference Fig.10 and Fig.11: A dismantling unit 5 is also provided in the shell 1, and the dismantling unit 5 includes a lifting rod 51 and a clamping rod 52. The lifting rod 51 is arranged on one side of the experimental table 2 in the horizontal direction, and two clamping rods 52 are provided. The two clamping rods 52 are symmetrically arranged about the lifting rod 51, and the extension direction of the clamping rod 52 is parallel to the extension direction of the lifting rod 51. The two clamping rods 52 can rotate around the axis of the lifting rod 51 at the same time to approach or move away from each other. When the experimental table 2 bears the insulating silicone tape 3 and is located directly below the camera 41, the lifting rod 51 passes through the lower part of the insulating silicone tape 3, and the clamping rod 52 is located above the insulating silicone tape 3. After the test is completed, the lifting rod 51 and the clamping rod 52 rise synchronously in the vertical direction, and the two clamping rods 52 rotate around the axis of the lifting rod 51 and approach each other. After approaching each other, the two clamping rods 52 fold the insulating silicone tape 3 in half and are located below the lifting rod 51. The clamping rod 52 is driven by hydraulic pressure.

[0039] After the heating is completed, the glue on the insulating silicone tape 3 will melt due to the high temperature. The traditional operation method is mostly for the staff to remove it manually, and the molten glue will inevitably stick to the hands of the staff. Therefore, regardless of whether the staff wears gloves or not, during the process of removing the insulating silicone tape 3, the staff's hands or gloves will be stuck with glue. Therefore, when taking the next test sample, the glue will inevitably stick to the new test sample. The test sample refers to the insulating silicone tape 3, and the excess glue attached to the surface of the insulating silicone tape 3 will inevitably affect the test results. In order to ensure the accuracy of the test, a removal unit 5 is set on one side of the experimental table 2. The tested insulating silicone tape 3 is automatically removed by the removal unit 5, which avoids the staff from removing the residual glue on the previous set of insulating silicone tapes 3 when installing the insulating silicone tape 3. The molten glue is adhered to the insulating silicone tape 3 of this group. When testing, the test bench 2 is moved to the side of the removal unit 5 under the drive of the slide 12. At this time, the two support blocks 21 on the test bench 2 lift the insulating silicone tape 3, and the lifting rod 51 passes through the lower part of the lifted insulating silicone tape 3. After the test, the lifting rod 51 rises in the vertical direction, and the clamping rod 52 rises synchronously with the lifting rod 51. During the rising process of the lifting rod 51, the insulating silicone tape 3 is lifted, and the connection between the insulating silicone tape 3 and the support block 21 is gradually separated. When the lifting rod 51 has not risen to the highest position, the clamping rods 52 on both sides of the lifting rod 51 approach each other and fold and fit the insulating silicone tape 3. Then the lifting rod 51 continues to rise, and the end of the insulating silicone tape 3 is completely separated from the upper part of the support block 21, thereby completing the automatic removal of the insulating silicone tape 3 after the test.

[0040] Reference Figure 7: A water-absorbent cotton 53 is provided on the outer sleeve of the lifting rod 51, and the water-absorbent cotton 53 is in direct contact with the rubber-coated surface of the insulating silicone belt 3. A water supply groove is opened inside the lifting rod 51, and a water supply hole is opened on the side wall of the lifting rod 51 in the radial direction. The water supply hole and the water supply groove are connected with each other. There is clean water in the water supply groove. The water supply groove supplies water to the water-absorbent cotton 53 through the water supply hole, and the water-absorbent cotton 53 is always in a moist state.

[0041] A water supply pipe 54 connected to the water supply trough is arranged on the side wall of the lifting rod 51, and one end of the water supply pipe 54 away from the lifting rod 51 is connected to the water tank 55. A water pump 56 is arranged on the water supply pipe 54. The water pump 56 is used to extract a certain amount of water stored in the water tank 55 and discharge the clean water into the water supply trough through the water supply pipe 54, so that the water supply trough can inject the clean water into the absorbent cotton 53 through the water supply hole. When the test of the insulating silicone tape 3 is completed, the moisture on the absorbent cotton 53 will be completely evaporated, and the water pump 56 extracts a certain amount of clean water and injects it into the absorbent cotton 53 to restore the absorbent cotton 53 to a wet state. Then the lifting rod 51 drives the absorbent cotton 53 to rise. The rising absorbent cotton 53 contacts the glue-coated surface of the insulating silicone tape 3, and the glue-coated surface of the insulating silicone tape 3 cannot stick to the wet absorbent cotton 53. In this way, the insulating silicone tape 3 can be prevented from sticking to the lifting rod 51 after being removed.

[0042] Reference Fig. 9 , Fig.10 and Fig.13 : The dismantling unit 5 also includes a lifting unit 57, which is used to drive the lifting rod 51 and the clamping rod 52 to lift in the vertical direction. The lifting unit 57 includes a lifting frame 571 that moves in the vertical direction. The lifting rod 51 and the clamping rod 52 are both arranged on the lifting frame 571 and can be lifted and lowered synchronously with the lifting frame 571. A first threaded rod 572 is vertically penetrated on the lifting frame 571, and the first threaded rod 572 is threadedly matched with the lifting frame 571.

[0043] The lifting unit 57 further includes a guide rod 573 and a first rotation driver 574. The guide rod 573 is arranged on one side of the lifting rod 51 in parallel with the extension direction of the lifting rod 51. The first rotation driver 574 is arranged at the end of the first threaded rod 572. The first rotation driver 574 is preferably a servo motor. When the test is completed, the first rotation driver 574 starts and drives the first threaded rod 572 to rotate, so that the lifting frame 571 threadedly matched with the first threaded rod 572 rises in the vertical direction, thereby causing the lifting frame 571 to be arranged on the lifting frame 571. The lifting rod 51 and the clamping rod 52 rise synchronously. When the lifting frame 571 drives the lifting rod 51 and the clamping rod 52 to rise in the vertical direction, the clamping rods 52 arranged on both sides of the lifting rod 51 gradually descend from the top of the lifting rod 51 to the bottom of the lifting rod 51. After the lifting rod 51 lifts the middle part of the insulating silicone tape 3, the two clamping rods 52 can fold the insulating silicone tape 3 in half and stick them together, ensuring that the lifting rod 51 will not slip off the bottom of the insulating silicone tape 3 when the end of the insulating silicone tape 3 is separated from the upper part of the support block 21.

The lifting unit 57 rotates synchronously with the rotating disk 58. An electric push rod 575 is horizontally arranged on the lifting frame 571. The output end of the electric push rod 575 is fixedly connected to the end of the lifting rod 51. When the shell 1 is in a testing state, the output end of the electric push rod 575 is in an extended state. After the test is completed, the first driving unit 59 drives the rotating disk 58 to rotate 180 degrees, and after the rotating disk 58 stops rotating, the output end of the electric push rod 575 retracts.

[0045] The first driving unit 59 includes a gear ring 591, a gear 592 and a second rotation driver 593.

The second rotation driver 593 is used to drive the gear 592 to rotate. The second rotation driver 593 is preferably a servo motor. When the second rotation driver 593 is started, the second rotation driver 593 drives the gear ring 591 through the gear 592, thereby rotating the rotating disk 58. When the insulating silicone belt 3 on the experimental table 2 is in the test state, In the folded state, the output end of the electric push rod 575 faces the experimental table 2, and the output end of the electric push rod 575 is in the extended state. At this time, the lifting rod 51 is extended by the electric push rod 575 and is located directly below the insulating silicone belt 3, so that the lifting rod 51 can lift the bottom of the insulating silicone belt 3 when it rises. When the lifting rod 51 completely lifts the insulating silicone belt 3, the insulating silicone belt 3 is disconnected from the support block 21, and the first driving unit 59 drives the rotating disk 58 to rotate 180, and then the electric push rod 575 drives the lifting rod 51 to retract, and the lifting rod 51 is pulled out from the lower part of the insulating silicone belt 3. At the same time, the clamping rod 52 loosens the folded insulating silicone belt 3, so that the insulating silicone belt 3 can be discharged smoothly.

[0048] After the removal unit 5 removes the insulating silicone tape 3, the first driving unit 59 drives the rotating disk 58 to rotate 180 degrees, so that the lifting rod 51 and the clamping rod 52 drive and rotate the removed insulating silicone tape 3 180 degrees. At this time, the insulating silicone tape 3 is transferred into the collecting chamber 63. When the lifting rod 51 is retracted by the electric push rod 575 and the clamping rod 52 is released, the tested insulating silicone tape 3 falls into the collecting basket 64 under the action of the airflow for collection.

[0050] When the removal unit 5 removes the insulating silicone tape 3, the lifting rod 51 gradually rises in the vertical direction, and the second driving unit 24 is also started at the same time. The second driving unit 24 drives the two support blocks 21 to approach each other, so that the angle between the insulating silicone tape 3 and the upper end surface of the support block 21 gradually increases, which is more conducive to the falling off of the insulating silicone tape 3. The second driving unit 24 also includes a third rotation driver 242, which is arranged at the end of the second threaded rod 241. The third rotation driver 242 is used to drive the second threaded rod 241 to rotate. The third rotation driver 242 is preferably a servo motor.
