Abstract
Description
Technical Field
[0001] This utility model belongs to the field of adhesive performance testing technology, and in particular relates to an ultraviolet aging test chamber for testing adhesives used in bonding heat-sensitive motor magnets. Background Technology
[0002] During motor operation, heat-sensitive motor magnets generate heat due to electromagnetic induction. The adhesive used for bonding them must have excellent resistance to ultraviolet aging and thermal stability. If the adhesive deteriorates after being exposed to ultraviolet light, it can easily cause the magnets to fall off, affecting the normal operation of the motor. Therefore, an ultraviolet aging test chamber is required for testing.
[0003] Existing UV aging test chambers have low temperature control accuracy in practical use, making it impossible to simulate the specific temperature range when motor magnets are working. This makes it difficult to accurately test the UV aging resistance of adhesives under thermal conditions. Furthermore, they lack a dedicated fixing structure for the shape of motor magnets, which can easily shift during testing, affecting the accuracy of adhesive aging test results. They also cannot simultaneously monitor changes in adhesive bonding strength under UV irradiation and temperature, making it difficult to comprehensively evaluate the actual performance of the adhesive.
[0004] To address this issue, we propose an ultraviolet aging test chamber for testing adhesives used in the bonding of heat-sensitive motor magnets. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Reference Figure 1-6A UV aging test chamber for testing adhesive used in bonding heat-sensitive motor magnets includes a test chamber body 1. An intelligent controller 2 and a data transceiver 3 are fixedly connected to the inner wall of the test chamber body 1. Two UV lamps 4 are fixedly connected to the inner wall of the test chamber body 1. Two cabinet doors 15 are hinged inside the test chamber body 1. Two observation windows 16 are fixedly connected to the inner wall of each cabinet door 15. The cabinet doors 15 are used to seal the test chamber body 1 to ensure the airtightness of the adhesive during the test. The observation windows 16 allow for convenient viewing of the condition of the motor magnets inside the test chamber body 1.

A rubber sleeve 18 is fixedly connected to the outer surface of each auxiliary handle 17. The auxiliary handle 17 can provide a good force-bearing position for the cabinet door 15, increasing the convenience when opening or closing the cabinet door 15. The rubber sleeve 18 can increase the firmness when gripping the auxiliary handle 17.
[0027] Heating element 6 and cooler 7 are fixedly connected to the inner side wall of the test chamber body 1 respectively. A protective shell 19 is provided on the outer surface of the temperature sensor 5. The bottom surface of the protective shell 19 is fixedly connected to the inner bottom wall of the test chamber body 1. The protective shell 19 can provide protection for the temperature sensor 5, avoid interference from external objects to the temperature sensor 5, and effectively increase the service life of the temperature sensor 5.
[0028] A fixed base 8 is fixedly connected to the inner bottom wall of the test chamber body 1. A bidirectional screw 9 is rotatably connected inside the fixed base 8. Two arc-shaped clamps 10 are threadedly connected to the outer surface of the bidirectional screw 9. Each arc-shaped clamp 10 is slidably connected inside the fixed base 8. Two sets of connecting blocks 20 are fixedly connected to the bottom surface of the test chamber body 1. Each set of connecting blocks 20 is rotatably connected to a moving wheel 21. By utilizing the cooperation of the connecting blocks 20 and the moving wheels 21, the device can be easily moved. At the same time, it can also be quickly changed direction during movement, which increases the convenience of the device.
[0029] A main bevel gear 11 is fixedly connected to the outer surface of the bidirectional screw 9, and a secondary bevel gear 12 is rotatably connected inside the fixed base 8. An auxiliary bearing 22 is sleeved on the outer surface of the bidirectional screw 9 and embedded inside the fixed base 8. The auxiliary bearing 22 can reduce the friction generated by the bidirectional screw 9 when rotating, making the bidirectional screw 9 more sensitive when rotating, and also reducing the wear rate of the bidirectional screw 9 and increasing the durability of the bidirectional screw 9.
[0030] One end of the secondary bevel gear 12 is fixedly connected to a transmission rod 13. One end of the transmission rod 13 passes through the fixed base 8 and extends to one side of the fixed base 8. A rotating bearing 23 is sleeved on the outer surface of the transmission rod 13. The rotating bearing 23 is embedded in the interior of the fixed base 8. The rotating bearing 23 can reduce the friction generated by the transmission rod 13 when rotating, making the transmission rod 13 more sensitive when rotating. At the same time, it can also reduce the wear rate of the transmission rod 13 and increase the service life of the transmission rod 13.
[0031] Each arc-shaped clamp 10 has a fixedly connected patch pressure sensor 14 on its inner wall. Each patch pressure sensor 14 is electrically connected to the data transceiver 3 via a wire. The intelligent controller 2 is electrically connected to the ultraviolet lamp 4, temperature sensor 5, heating element 6, cooler 7, and data transceiver 3 via wires. One end of the transmission rod 13 is fixedly connected to a turntable 24. The outer surface of the turntable 24 is fixedly connected to a pull rod 25. By utilizing the cooperation of the turntable 24 and the pull rod 25, a good force point can be provided for the transmission rod 13, increasing the ease of rotation of the transmission rod 13 and improving the convenience of the device in use.
[0032] The working principle of this utility model is as follows: In use, first connect the intelligent controller 2, data transceiver 3, ultraviolet lamp 4, temperature sensor 5, heating element 6, cooler 7, and patch-type pressure sensor 14 to the power supply. Place the heat-sensitive motor magnet to be tested above the fixed base 8. Then, rotate the turntable 24 via the pull rod 25, thereby driving the transmission rod 13 and the secondary bevel gear 12 to rotate, and causing the main bevel gear 11 and the bidirectional screw 9 to rotate, driving the symmetrically arranged arc-shaped clamping plate 10 to approach the magnet until the patch-type pressure sensor 14 on the inner side of the arc-shaped clamping plate 10 captures the preset preload. At this time, the patch-type pressure sensor 14 transmits the initial pressure signal to the intelligent controller 2 via the data transceiver 3 as the reference data for subsequent bonding strength monitoring. Then, the intelligent controller 2 adjusts the temperature parameters, ultraviolet irradiation parameters, and bonding strength data acquisition frequency. At this time, the heating element 6 converts electrical energy into heat energy to heat the air inside the test chamber 1. The temperature sensor 5 collects the temperature data inside the test chamber 1 in real time and transmits the data... Feedback is sent to the intelligent controller 2. If the temperature is below the lower limit of the preset range, the power of the heating element 6 is increased. If the temperature is above the upper limit, the intelligent controller 2 starts the cooler 7 to reduce the temperature through cold air circulation. This accurately simulates the continuous heat environment generated by electromagnetic induction when the heat-sensitive motor magnetic tile is working. When the temperature stabilizes within the target range, the intelligent controller 2 sends a start command to the ultraviolet lamp 4, causing the ultraviolet lamp 4 to emit ultraviolet rays of corresponding intensity. Under the combined effect of temperature and ultraviolet light, the adhesive to be tested gradually ages, resulting in a decrease in the bonding tightness between the magnetic tile and the substrate. Under the constant pre-tightening force of the arc-shaped clamp 10, the magnetic tile will shift slightly away from the substrate. The patch-type pressure sensor 14 installed on the inner side of the arc-shaped clamp 10 captures the pressure change in real time and converts the pressure signal into an electrical signal, which is transmitted to the intelligent controller 2 through the data transceiver 3. The intelligent controller 2 automatically calculates the current adhesive strength attenuation value based on the previously calibrated correspondence, effectively increasing the effectiveness of the ultraviolet aging test chamber.
