Description

Technical Field

[0001] This utility model relates to the field of tape tear detection technology, specifically a tape tear detection device. Background Technology

[0002] In many fields such as packaging, electronics, and construction, adhesive tape is an indispensable bonding material, and its quality directly affects the packaging effect, service life, and stability of the production process. Tear strength is one of the key indicators for measuring the quality of adhesive tape; accurately testing the tear strength of adhesive tape is of great significance for ensuring product quality and reducing production risks.

[0003] According to patent document CN214703075U, a strength testing device for tape processing is disclosed, including a worktable with a cavity inside. A first rotating shaft is installed through the cavity, and a threaded block is provided on the outer wall of the first rotating shaft, located inside the cavity. A slide rod is fixedly connected to the top of the threaded block, and a baffle is installed through the top of the slide rod. One end of a spring is fixed to the outer wall of one end of the baffle, and the other end of the spring is connected to the outer wall of the top of the slide rod. A sliding plate is fixed to one side of the slide rod, and the outer wall of the sliding plate is provided with locking teeth. This strength testing device for tape processing can quantitatively test multiple sets of tapes of different lengths, the same material, and the same thickness.

[0004] Currently, most tape tear testing devices on the market are only suitable for testing in room temperature environments. However, tape properties change significantly with temperature; at high temperatures, adhesion and toughness decrease, while at low temperatures, tape becomes hard and brittle, exhibiting significantly different tear characteristics. Existing devices lack temperature control functions and cannot simulate the temperature environment of real-world usage scenarios, making it difficult for test results to reflect the actual performance of the tape. This makes it difficult for manufacturers to control the quality of tape at different temperatures, easily leading to problems such as loose product packaging and detached electronic components due to the use of substandard tape, resulting in economic losses.

However, existing devices lack temperature regulation functions and cannot simulate the temperature environment of real-world usage scenarios, making it difficult for test results to reflect the actual performance of the tape. This makes it difficult for manufacturers to control the quality of tape at different temperatures, easily leading to problems such as loose product packaging and detached electronic components due to the use of substandard tape, resulting in economic losses.

One side of the diversion pipe 208 is connected to a nozzle 209. A temperature sensor 210 is fixedly connected to the bottom right side of the inner cavity of the housing 1. By setting the temperature regulating mechanism 2 and setting the temperature value through an external PLC controller, the temperature sensor 210 detects the temperature inside the housing 1. If the temperature value of the cavity is detected to be lower than the set value, the heating plate 201 will be activated. If the temperature value is detected to be higher than the set value, the thermoelectric cooler 202 and the heat sink 203 will be activated. At the same time, the fan 206 will be activated to extract the gas from the top of the cavity of the housing 1 through the suction head 204 and the confluence pipe 205. Then, the gas will be sprayed to the bottom of the cavity of the housing 1 through the exhaust pipe 207, the diversion pipe 208 and the nozzle 209, so that the gas flows and the temperature is evenly distributed. A fixed base is fixedly connected to one side of the fan 206, and one side of the fixed base is fixedly connected to the housing 1. By setting the fixed base, the operation of the fan 206 is stabilized and the fan 206 is limited. Rectangular slots are opened on both sides of the top of the housing 1, and the inner cavity of the rectangular slots is fixedly connected to the thermoelectric cooler 202. By setting the rectangular slots, the operation of the thermoelectric cooler 202 is stabilized and the thermoelectric cooler 202 is limited.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4On the other side of the housing 1, a detection mechanism 3 is provided. The detection mechanism 3 includes a support plate 301, one side of which is fixedly connected to the housing 1. An electric telescopic rod 302 is fixedly connected to the top of the housing 1 and to the left side of the central axis. A horizontal plate 303 is fixedly connected to the top of the electric telescopic rod 302. Vertical columns 304 are fixedly connected to the four corners of the bottom of the horizontal plate 303. A pressure plate 305 is fixedly connected to the bottom of the vertical columns 304. A motor 306 is fixedly connected to the central axis of the top of the housing 1.

A rectangular plate 312 is fixedly connected to the bottom of the pressure sensor 311, and a spring 313 is fixedly connected to the bottom of the rectangular plate 312. A pressure rod 314 is fixedly connected to the bottom of the spring 313. By setting the detection mechanism 3, before adjusting the temperature, the two ends of the tape to be tested are placed on the top of the two support plates 301 respectively. Then, the electric telescopic rod 302 is started by the external PLC controller. The electric telescopic rod 302 drives the horizontal plate 303 to move, the horizontal plate 303 drives the vertical column 304 to move, and the vertical column 304 drives the pressure plate 305 to move, thereby fixing the two ends of the tape. The detected temperature value is the same as the set value. Afterwards, the pressure value is set, and motor 306 is started. Motor 306 drives the drive gear 307 to rotate, which in turn drives the driven gear 308 to rotate. Driven gear 308 drives the lead screw 309 to rotate, which in turn moves the adjusting plate 310. The adjusting plate 310 moves the pressure sensor 311, which in turn moves the rectangular plate 312. The rectangular plate 312 moves the spring 313, which in turn moves the pressure rod 314. After the pressure rod 314 contacts the material, the spring 313 compresses. At this time, the pressure sensor 311 detects an increase in pressure. Once the detected pressure value matches the set value, motor 306 stops operating. The material can then be observed through the transparent door. Whether it is damaged; the inner cavity of the adjusting plate 310 and the rectangular plate 312 are both provided with round holes, and the inner cavity of the round holes is slidably connected to the slide rod, and the bottom of the slide rod is fixedly connected to the pressure rod 314. By setting the round holes and the slide rod, the operation of the pressure rod 314 is stabilized and the pressure rod 314 is balanced and supported; the top of the surface of the lead screw 309 is movably connected to the housing 1 through the bearing, and the two sides of the front of the housing 1 are movably connected to the transparent door. By setting the bearing, the operation of the lead screw 309 is stabilized and the lead screw 309 is limited; the four corners of the top of the housing 1 are provided with movable holes, and the inner cavity of the movable holes is slidably connected to the vertical column 304. By setting the movable holes, not only is the operation of the vertical column 304 stabilized, but the vertical column 304 is also moved conveniently.

[0024] Working principle: By setting the temperature control mechanism 2, the temperature value is set by the external PLC controller. The temperature sensor 210 detects the temperature value inside the housing 1. If the detected temperature value is lower than the set value, the heating plate 201 will be activated. If the detected temperature value is higher than the set value, the semiconductor cooling chip 202 and the heat sink 203 will be activated. At the same time, the fan 206 will be activated. The gas at the top of the housing 1 is extracted through the air extraction head 204 and the confluence pipe 205. Then, the gas is sprayed to the bottom of the housing 1 through the exhaust pipe 207, the diversion pipe 208 and the nozzle 209, so that the gas flows and the temperature is evenly distributed.

[0025] By setting up the detection mechanism 3, before adjusting the temperature, the two ends of the tape to be tested are placed on top of the two support plates 301 respectively. Then, the electric telescopic rod 302 is started by the external PLC controller. The electric telescopic rod 302 drives the horizontal plate 303 to move, the horizontal plate 303 drives the vertical column 304 to move, and the vertical column 304 drives the pressure plate 305 to move, thereby fixing the two ends of the tape. After the detected temperature value is the same as the set value, the pressure value is set, and the motor 306 is started. The motor 306 drives the drive gear 307 to rotate, and the drive gear 307 drives the driven gear 305. When motor 308 rotates, driven gear 308 drives lead screw 309 to rotate. Lead screw 309 drives adjusting plate 310 to move. Adjusting plate 310 drives pressure sensor 311 to move. Pressure sensor 311 drives rectangular plate 312 to move. Rectangular plate 312 drives spring 313 to move. Spring 313 drives pressure rod 314 to move. After pressure rod 314 contacts the material, spring 313 will compress. At this time, pressure sensor 311 will detect an increase in pressure value. After detecting that the pressure value is the same as the set value, motor 306 stops working. At this time, the material can be observed through the transparent door to see if it is damaged.
