Description

Technical Field

[0001] This application relates to the field of tape adhesion testing technology, and in particular to a tape adhesion testing device. Background Technology

[0002] In modern industry and daily life, tape is a widely used adhesive material. Its adhesive properties directly affect the performance and safety of the product. Accurately testing the adhesive strength of tape has become a key link in quality control and product development.

[0003] A search revealed a patent document with authorization announcement number CN206020249U, which discloses a tape adhesion testing device. The device includes a base plate, a vertical plate, a force measuring device, a tape ring suspension device, and a winding device. The force measuring device includes a force gauge for testing tape adhesion, a pad connected to the vertical plate, and a pressure plate for fixing the force gauge to the pad. The tape ring suspension device includes a pin, a handle mounted on the pin, and a connector for connecting the pin to a hook of the force gauge. The winding device includes a fixed base on the base plate and a motor mounted on the fixed base, with a winding wheel fixed to the output end of the motor. During testing, the tape ring is positioned directly below the force gauge, with the first end of the tape wound around the winding wheel. The motor drives the winding wheel in a circular motion, causing the tape to move and wrap evenly around the winding wheel. This device is convenient for determining the adhesion force of adhesive tape, offering high efficiency, low labor intensity, and a small footprint.

[0004] In practical use, it was found that the existing device lacks a standardized pre-compression process, and the test data fluctuates greatly due to air residue and uneven pressure when the tape is applied, making it difficult to simulate the actual use scenario. Therefore, we proposed a tape adhesion testing device to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a tape adhesion testing device that can automatically pre-tighten the tape, simulate actual pasting conditions, and improve the accuracy of testing.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a tape adhesion testing device, including a base, a functional box fixedly installed on the top left side of the base, a motor fixedly installed on the inner wall of the left side of the functional box, a winding mechanism provided between the motor and the functional box, a pre-compression mechanism provided on the functional box, a detection cylinder fixedly installed on the top right side of the functional box, a detection mechanism provided inside the detection cylinder; a mounting frame provided below the detection cylinder, a rotating mechanism provided on the mounting frame, and a fixing mechanism provided inside the mounting frame.

[0007] A further configuration of this application is: the winding mechanism includes a drive shaft and a winding roller, the right end of the motor output shaft is fixedly mounted with the drive shaft, the right end of the drive shaft extends to the outside of the function box, and the winding roller is fixedly sleeved on the drive shaft.

[0008] By adopting the above technical solution and by setting up a winding mechanism, the motor can drive the winding roller to rotate, thereby achieving the purpose of winding the tape by the winding roller.

[0009] A further configuration of this application is as follows: the pre-compression mechanism includes a rotating shaft and a pre-compression roller. The rotating shaft is rotatably installed on the inner wall of the left side of the functional box, and the right end of the rotating shaft extends to the outside of the functional box.

[0011] A further configuration of this application is: the transmission mechanism includes two transmission wheels and a transmission belt, with transmission wheels fixedly sleeved on both the rotating shaft and the drive shaft, the transmission wheels located inside the functional box, and the same transmission belt sleeved on both transmission wheels.

[0012] By adopting the above technical solution and by setting up a transmission mechanism, the drive shaft can drive the rotating shaft to rotate synchronously.

[0013] A further configuration of this application is as follows: the detection mechanism includes a sliding plate, a sliding rod, a pressure sensor, and a spring. The sliding plate is slidably installed inside the detection cylinder, and the sliding rod is fixedly installed at the bottom of the sliding plate. The bottom end of the sliding rod extends to the bottom of the detection cylinder and is fixedly connected to the top of the mounting frame. A pressure sensor is provided on the inner wall of the bottom of the detection cylinder. A spring is sleeved on the sliding rod, and the top end of the spring is fixedly connected to the bottom of the sliding plate. The bottom end of the spring is adapted to the pressure sensor.

[0014] By adopting the above technical solution and setting up a detection mechanism, the tension generated by the tape during the winding process can be converted into an electrical signal by a pressure sensor and transmitted to the controller, thereby achieving the purpose of accurately quantifying the adhesive force during the tape peeling process.

Hydraulic cylinders are fixedly installed on the top and bottom of the fixing seat, and arc-shaped top blocks are fixedly installed on the ends of the output shafts of the two hydraulic cylinders that are far apart from each other.

[0018] By adopting the above technical solution and by setting a fixing mechanism, the hydraulic cylinder can push the arc-shaped top block to expand outward, and the outer anti-slip pad can tightly press against the inner wall of the inner ring of the tape, thereby achieving the purpose of firmly fixing the tape roll.

[0023] A further feature of this application is that an anti-slip pad is provided on the outer side of the arc-shaped top block, and the anti-slip pad is adapted to the inner ring of the tape.

[0024] By adopting the above technical solution and setting anti-slip pads, the arc-shaped top block is more firmly fixed to the inner ring of the tape, thereby improving the stability of the test.

[0025] The beneficial effects of this application are:

After processing by the algorithm, it is converted into an adhesive force value, which is displayed and recorded synchronously. This enables precise quantification of the adhesive force during the tape peeling process, meeting the adhesive force testing requirements of different tape products.

[0038] Specifically, the pre-compression mechanism includes a rotating shaft 3 and a pre-compression roller 301. The rotating shaft 3 is rotatably installed on the inner wall of the left side of the function box 2. The right end of the rotating shaft 3 extends to the outside of the function box 2. The rotating shaft 3 is located above and behind the motor 201. The pre-compression roller 301 is fixedly sleeved on the rotating shaft 3. A transmission mechanism is provided between the rotating shaft 3 and the drive shaft 202.

[0039] Specifically, the transmission mechanism includes two transmission wheels 302 and a transmission belt 303. The transmission wheels 302 are fixedly mounted on both the rotating shaft 3 and the drive shaft 202. The transmission wheels 302 are located inside the functional box 2, and the same transmission belt 303 is mounted on both transmission wheels 302.

[0040] Specifically, the detection mechanism includes a slide plate 401, a slide rod 402, a pressure sensor 403, and a spring 404. The slide plate 401 is slidably installed inside the detection cylinder 4. The slide rod 402 is fixedly installed at the bottom of the slide plate 401. The bottom end of the slide rod 402 extends to the bottom of the detection cylinder 4. The bottom end of the slide rod 402 is fixedly connected to the top of the mounting bracket 5. The pressure sensor 403 is installed on the inner wall of the bottom of the detection cylinder 4. The spring 404 is sleeved on the slide rod 402. The top end of the spring 404 is fixedly connected to the bottom of the slide plate 401. The bottom end of the spring 404 is adapted to the pressure sensor 403.

[0041] Specifically, the rotating mechanism includes a rotating column 501 and a fixed seat 502. The rotating column 501 is rotatably mounted on the inner left side of the mounting bracket 5, and the fixed seat 502 is fixedly mounted on the right end of the rotating column 501.

[0042] Specifically, the fixing mechanism includes two hydraulic cylinders 6 and an arc-shaped top block 601. The top and bottom of the fixing base 502 are fixedly installed with hydraulic cylinders 6, and the arc-shaped top block 601 is fixedly installed at the ends of the output shafts of the two hydraulic cylinders 6 that are far apart from each other.

[0043] Specifically, an inner ring 7 of adhesive tape is sleeved on the outer side of the arc-shaped top block 601, and an adhesive tape 701 is provided on the inner ring 7. The take-up roller 203 and the pre-pressure roller 301 are adapted to the adhesive tape 701.

[0044] Specifically, a controller 101 is provided on the top right side of the base 1, and the controller 101 is electrically connected to the pressure sensor 403.

[0045] Specifically, an anti-slip pad is provided on the outer side of the arc-shaped top block 601, and the anti-slip pad is compatible with the inner ring 7 of the tape.

[0046] In this application, during operation, the inner ring 7 of the tape 701 is first placed on the outside of the two arc-shaped top blocks 601. By activating the two hydraulic cylinders 6 of the fixing mechanism, the output shafts can push the arc-shaped top blocks 601 to expand outward, allowing the outer anti-slip pads to tightly press against the inner wall of the inner ring 7 of the tape, thus achieving the purpose of firmly fixing the tape roll. Subsequently, one end of the tape 701 is glued and fixed to the take-up roller 203. By activating the motor 201, its output shaft can drive the drive shaft 202 and the take-up roller 203 to rotate, generating a winding tension on the tape. The fixed seat 502 can drive the rotating column 501 to rotate flexibly within the mounting frame 5, thereby releasing the tape 701. At the same time, the transmission wheel 302 on the drive shaft 202 can drive the transmission wheel 302 on the rotating shaft 3 via the transmission belt 303, enabling the rotating shaft 3 to drive the pre-pressure roller 301 to rotate at a matching speed. This system can apply uniform pressure to the surface of tape 701 along its winding path, eliminate air between tape 701 and the contact surface through rolling, ensure full contact between the adhesive and the substrate, simulate actual bonding conditions, and accurately quantify the adhesive force during tape peeling, ensuring data reliability. During tape 701 winding, the tension is transmitted to the slide bar 402 through the mounting bracket 5, allowing it to slide downwards within the detection cylinder 4, compressing the spring 404 and pressing the pressure sensor 403 at the bottom. The elastic deformation of the spring 404 and the adhesive force of the tape form a force balance. The pressure sensor 403 converts the real-time pressure signal into an electrical signal, which is transmitted to the controller 101. After algorithm processing, it is converted into an adhesive force value, which is displayed and recorded synchronously. This allows for accurate quantification of the adhesive force during tape peeling, meeting the adhesive force testing needs of different tape products.
