Description

Technical Field

[0001] This utility model relates to the field of electrostatic tape testing technology, and in particular to a device for testing the temperature resistance of electrostatic tape. Background Technology

[0002] Electrostatic tape is a special type of tape that uses electrostatic adsorption to achieve its adhesive function. Compared with traditional pressure-sensitive tape, electrostatic tape has advantages such as no residue, reusability, and environmental friendliness. However, its adsorption performance is significantly affected by ambient temperature and humidity, as well as material properties. At high temperatures, the molecular structure of electrostatic tape may change, leading to a decrease or failure of its electrostatic adsorption force. Therefore, temperature resistance is a key indicator of its reliability. Currently, the industry mainly evaluates its temperature resistance through high-temperature aging tests. Test conditions typically simulate extreme temperatures in real-world applications (e.g., 80℃-150℃), and the test items include peel strength retention, dimensional stability, and appearance changes.

[0003] A search revealed that patent CN209992421U discloses a device for testing the temperature resistance of electrostatic tape. The device consists of two testing chambers. The electrostatic tape to be tested is placed in one chamber, while a standard electrostatic tape is placed in the other chamber. The two types of electrostatic tape are tested simultaneously, providing strong comparability and allowing for a clear and intuitive understanding of the heat resistance of the electrostatic tape to be tested.

[0004] However, the aforementioned device can only test two sets of tapes at a time, and the results are obtained through visual observation, which cannot provide accurate data. If multiple sets of tapes are tested, cross-sectional comparisons of the data are not possible. Furthermore, the adhesive strength of the tape varies depending on the pressure applied when it is applied to the surface of the movable cover, resulting in the device only being able to roughly assess tape performance rather than providing accurate results. Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for testing the temperature resistance of electrostatic tape.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a device for testing the temperature resistance of electrostatic tape, comprising a box, a partition horizontally fixed at the bottom of the box, and a heating component disposed below the partition, a placement platform fixed on the upper surface of the partition, a vertical tube fixed on one side of the upper surface of the box, an L-shaped plate slidably connected inside the vertical tube, a sliding sleeve slidably connected to the top surface of the L-shaped plate, a pressing component fixed on the lower surface of the sliding sleeve, and multiple steel plates for bonding electrostatic tape matched with the pressing component, a controller fixed on the outer wall of the box, and a side door rotatably connected to one side of the box above the partition via a hinge.

[0007] Furthermore, the heating component includes a U-shaped bend, with both ends of the bend penetrating through a partition and communicating with the top of the housing, and an electric heating wire fixed inside the bend.

[0008] Furthermore, the heating assembly also includes a motor fixed to the bottom of the outer wall of the housing, the output end of the motor is fixedly connected to a horizontal shaft, the horizontal shaft extends into the inside of the curved tube and is fixedly connected to a fan blade.

[0009] Furthermore, a temperature sensor is installed on the top wall of the housing, and the temperature sensor, motor, and electric heating wire are all electrically connected to the controller.

[0010] Furthermore, the clamping assembly includes a vertical rod fixed to the lower surface of the sliding sleeve, a sleeve slidably connected to the bottom surface of the vertical rod, a spring fixedly connected to the inner bottom wall of the sleeve and the bottom end of the vertical rod, a U-shaped plate fixed to the bottom end of the sleeve, and a pressure roller rotatably connected inside the U-shaped plate.

[0011] Furthermore, the top sidewall of the vertical tube is connected to a locking bolt via a threaded rotatable connection.

[0012] Furthermore, the inner walls at both ends of the sliding sleeve are provided with two side grooves, one above the other. Rollers are rotatably connected inside the side grooves.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a device for testing the temperature resistance of electrostatic tape is disclosed. The device includes a housing 1, a partition 2 horizontally fixed at the bottom of the housing 1, a heating component 4 below the partition 2, a placement platform 3 fixed on the upper surface of the partition 2, a vertical tube 5 fixed on one side of the upper surface of the housing 1, an L-shaped plate 6 slidably connected inside the vertical tube 5, a sliding sleeve 7 slidably connected to the top surface of the L-shaped plate 6, a pressing component 8 fixed on the lower surface of the sliding sleeve 7, and multiple steel plates 9 for bonding electrostatic tape matched with the pressing component 8. A controller 10 is fixed on the outer wall of the housing 1, and a side door 11 is hinged and rotatably connected to one side of the housing 1 above the partition 2.

[0023] The heating component 4 includes a U-shaped bend 41, with both ends of the bend 41 passing through the partition 2 and communicating with the top of the housing 1. An electric heating wire 42 is fixed inside the bend 41.

[0024] Since both ends of the bend 41 are connected to the top space of the box 1, when the electric heating wire 42 is activated to heat the air inside the bend 41, the air above the box 1 is heated.

[0025] The heating assembly 4 also includes a motor 45 fixed to the bottom of the outer wall of the housing 1. The output end of the motor 45 is fixedly connected to a horizontal shaft 43, which extends into the inside of the bent tube 41 and is fixedly connected to a fan blade 44.

[0026] In this embodiment, the horizontal shaft 43 is rotatably connected to the side wall of the housing 1 and the bend 41 by bearings. By starting the motor 45 to drive the fan blade 44 to rotate, the air inside the bend 41 can be driven to flow, so that the air above the housing 1 and the air inside the bend 41 circulate, thereby accelerating the heating of the air above the housing 1.

[0027] A temperature sensor is installed on the top wall inside the housing 1. The temperature sensor, motor 45 and electric heating wire 42 are all electrically connected to the controller 10.

[0028] In this embodiment, the temperature sensor is an LM35 (analog output) with a measurement range of -55°C to +150°C; the heating wire 42 is a resistance heating wire; and the controller 10 is a Siemens SIMATIC KP1200 series (HMI+PLC integrated machine) controller with a screen, specifically model KP1212 Basic PN (6AV2123-2GB03-0AX0). The temperature sensor monitors the internal temperature of the enclosure 1 in real time, and then feeds the temperature information back to the controller 10. The controller 10 then controls whether the heating wire 42 and the motor 45 operate, thereby maintaining a stable temperature inside the enclosure 1 for monitoring.

[0029] The clamping assembly 8 includes a vertical rod 81 fixed to the lower surface of the sliding sleeve 7. A sleeve 82 is slidably connected to the bottom surface of the vertical rod 81. A spring 83 is fixedly connected to the bottom wall of the sleeve 82 and the bottom of the vertical rod 81. A U-shaped plate 84 is fixed to the bottom of the sleeve 82. A pressure roller 85 is rotatably connected inside the U-shaped plate 84.

[0030] In this embodiment, the pressure roller 85 is made of solid metal. When the steel plate 9 with adhesive tape is placed under the pressure roller 85, the L-shaped plate 6 is pressed down along the vertical tube 5 so that the pressure roller 85 presses on the surface of the tape until the spring 83 is compressed to the maximum extent. At this time, the sliding sleeve 7 can be moved along the L-shaped plate 6 so that the pressure roller 85 rolls the tape on the surface of the steel plate 9. If there are multiple steel plates 9, it can be ensured that the tape on the surface of each steel plate 9 is squeezed with the same force.

[0031] The top side wall of the vertical tube 5 is penetrated and connected by a locking bolt 51 via a threaded rotation.

[0032] After pressing down the L-shaped plate 6 so that the pressure roller 85 presses against the tape on the surface of the steel plate 9, tighten the locking bolt 51 to fix the L-shaped plate 6.

[0033] The inner walls of both ends of the sliding sleeve 7 are provided with two side grooves 71, one above the other. Rollers 72 are rotatably connected inside the side grooves 71. The rollers 72 are in contact with the surface of the L-shaped plate 6. A handle is fixed on the upper surface of the sliding sleeve 7.

[0034] By setting rollers 72, the friction of the sliding sleeve 7 when it moves along the L-shaped plate 6 can be reduced, and the sliding sleeve 7 can be moved easily by holding the handle.

[0035] Working principle: First, multiple electrostatic tapes to be tested are adhered to the lower surfaces of multiple steel plates 9. Then, multiple steel plates 9 are placed simultaneously under the pressure roller 85, and the L-shaped plate 6 is pressed down so that the pressure roller 85 presses against the tape surface. Then, the locking bolt 51 is tightened to fix the L-shaped plate 6. Next, the sliding sleeve 7 is moved to drive the pressure roller 85 to move, and the pressure roller 85 is used to roll the tape. After the rolling is completed, the locking bolt 51 is loosened, the L-shaped plate 6 is pulled upward to reset, and multiple steel plates 9 are removed and placed on the placement platform 3 inside the box 1. Then, the side door 11 is closed (the side door 11 is magnetically fixed on the side away from the hinge). Then, the inside of the box 1 is heated by the heating component 4. After heating for a specified time, the steel plates 9 are taken out and placed on the tensile tester to test the peel force. Finally, the peel force is recorded. (The tensile tester for measuring peel force is existing technology in this field, and the principle will not be described here.)

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
