Description

Technical Field

[0001] This utility model relates to the field of differential scanning calorimetry, specifically a differential scanning calorimeter for the production of adhesives for drone assembly. Background Technology

[0002] Specialty adhesives play a crucial role in the manufacturing and assembly of drones. They are widely used in key processes such as bonding core structural components, laminating composite skins, and fixing and sealing electronic components. The properties of these adhesives, such as curing characteristics, glass transition temperature, thermal stability, crystallization behavior, and curing enthalpy, directly determine the mechanical strength and durability of the bonded joints, as well as the reliability and safety of the final drone product under complex operating conditions. Differential scanning calorimetry (DSC) is a core analytical instrument used to measure the thermodynamic properties of the aforementioned materials. Its basic principle is to measure the relationship between the heat flow difference or power difference between the input sample and the reference material and temperature under programmed temperature control. By analyzing the DSC curve, a series of key parameters such as the curing start temperature, peak temperature, curing end temperature, degree of curing, glass transition temperature, and thermal decomposition temperature of the adhesive can be obtained. These data have irreplaceable guiding significance for the formulation development, production process optimization, quality control, and batch consistency inspection of drone adhesives.

[0003] Existing differential scanning calorimeters typically employ simultaneous testing of two sets of materials to ensure accurate data comparison. However, the adhesive must be placed stably and safely to prevent mechanical jamming or minor collisions during its insertion into the testing chamber, which could cause the adhesive to shake or disperse within the container, affecting the differential scanning calorimeter's scanning results and consequently impacting the data acquisition accuracy during adhesive production. Therefore, we propose a differential scanning calorimeter for adhesive production using unmanned aerial vehicles (UAVs). Utility Model Content

[0004] The purpose of this invention is to provide a differential scanning calorimeter for the production of adhesives for drone assembly, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a differential scanning calorimeter for producing adhesives for drone assembly, comprising a body, two sets of detection chambers opened on the front of the body, a door hinged to the inner wall of the end of the detection chamber, and a tray slidably installed on the inner surface of the bottom of the detection chamber. The detection chamber is provided with a guide assembly to restrict the horizontal sliding of the tray. The guide assembly includes T-shaped grooves opened on the inner walls of the left and right sides of the detection chamber. A T-shaped slider is slidably installed on the inner surface of the T-shaped groove. A stabilizing plate is fixedly installed on the side wall of the T-shaped slider. A swing groove is opened on the inner wall of the stabilizing plate near the door. Straight grooves are opened on the inner walls of the two sides of the swing groove. A sliding rod is movably installed on the inner surface of the straight groove. A connecting rod is fixedly installed through the outer wall of the sliding rod. The end of the connecting rod away from the sliding rod is hinged to the upper surface of the tray.

[0006] Preferably, the number of the guiding components is set to two sets, and the two sets of guiding components are mirror images of each other on both sides of the detection cavity.

[0007] Preferably, the width of the connecting rod is adapted to the swing groove, and the outer diameter of the sliding rod is adapted to the width of the straight groove.

[0008] Preferably, the bottom inner surface of the detection cavity is provided with a support component, the support component includes a limiting groove, the limiting groove is formed on the bottom inner surface of the tray, a top block is fixedly installed on the bottom inner wall of the detection cavity, side plates are fixedly installed on both sides of the top block, a movable cavity is formed on the inner wall of the tray, a lifting plate is slidably installed on the inner surface of the movable cavity, an arc-shaped block is fixedly installed on the bottom surface of the lifting plate, a contact rod is fixedly installed on the top surface of the lifting plate, and a wave groove is formed on the top surface of the contact rod.

[0009] Preferably, the limiting groove includes a rectangular groove whose size is adapted to the top block and flat grooves on both sides of the rectangular groove, and the flat grooves slide in conjunction with the side plate.

[0010] Preferably, the inner top wall of the tray has a circular hole adapted to the contact rod, and the contact rod slides in contact with the circular hole.

[0011] Preferably, the side of the top block and the arc-shaped block that are close to each other is provided as an arc-shaped surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are: through the sliding cooperation of the T-shaped groove and the T-shaped slider, as well as the coordinated movement of the connecting rod and the sliding rod in the straight groove and the swing groove, it is ensured that the tray remains horizontal and stable throughout the entire process of pulling out and pushing back the detection chamber. Even if the tray carries a heavy glue sample, its front end can obtain continuous upward pulling support, avoiding instability of the sample container caused by the tray sinking or tilting, improving the stability and safety of the sample during the placement, transfer and detection preparation stages, reducing interference caused by external operations, and ensuring the repeatability and accuracy of the detection data.

[0013] Secondly, the curved surfaces of the top block and the arc-shaped block make contact, smoothly lifting the lifting plate upwards, which in turn drives the contact rods distributed in a circular array to rise, slightly lifting the sample container off the tray surface. The corrugated grooves and frosted surfaces at the top of the contact rods increase the friction with the bottom of the container, effectively preventing horizontal sliding. At the same time, the bottom gap formed by the lifting ensures air circulation between the container and the tray, which is conducive to the uniform transfer and exchange of heat and avoids the impact of local heat accumulation or uneven heat dissipation on the thermal analysis results.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a technical solution: such as Figures 1-5 The differential scanning calorimeter shown includes a body 1, two sets of detection chambers 2 opened on the front of the body 1, a door 3 hinged to the inner wall of the end of the detection chamber 2, and a tray 4 slidably installed on the inner surface of the bottom of the detection chamber 2. The detection chamber 2 is provided with a guide component to restrict the horizontal sliding of the tray 4. The guide component includes T-shaped grooves 7 opened on the inner walls of the left and right sides of the detection chamber 2. T-shaped sliders 8 are slidably installed on the inner surface of the T-shaped grooves 7. A stabilizing plate 9 is fixedly installed on the side wall of the T-shaped slider 8. A swing groove 11 is opened on the inner wall of the end of the stabilizing plate 9 near the door 3. Straight grooves 10 are opened on the inner walls of the two sides of the swing groove 11. A sliding rod 6 is movably installed on the inner surface of the straight groove 10. A connecting rod 5 is fixedly installed through the outer wall of the sliding rod 6. The end of the connecting rod 5 away from the sliding rod 6 is hinged to the upper surface of the tray 4.

[0022] Handles are provided on the side of the door 3 and the upper surface of the tray 4 to facilitate operation by staff. Meanwhile, a detection module is installed in the top cavity of the machine body 1, which can measure a series of key parameters of the glue sample in the detection chamber 2 in real time, such as the curing start temperature, peak temperature, curing end temperature, degree of curing, glass transition temperature, and thermal decomposition temperature. At the same time, a touch screen is also provided on the front of the machine body 1. The above measurement data can be displayed on the touch screen under the control of the control terminal, which is convenient for the operation of the experimenter. The above detection equipment adopts the content disclosed in the prior art, so it will not be specifically described in this case.

[0023] Please see Figures 2-3 The number of guide components is set to two sets, which are mirror images of each other on both sides of the detection cavity 2. The two sets of guide components can ensure that the tray 4 remains horizontal when it is pulled outward, and at the same time, it can also ensure its stability.

[0024] The width of the connecting rod 5 is adapted to the swing groove 11, and the outer diameter of the sliding rod 6 is adapted to the width of the straight groove 10. There is no motion interference between the connecting rod 5 and the swing groove 11, and the sliding rod 6 can also slide within the straight groove 10. When the tray 4 is completely retracted into the detection chamber 2, the sliding rod 6 is at the end of the straight groove 10 away from the door 3. Specifically, during the process of pulling out the tray 4, driven by the connecting rod 5, the sliding rod 6 will slide a certain distance along the straight groove 10 until the sliding rod 6 and the end of the straight groove 10 near the door 3 are pressed together. Then, the outward sliding of tray 4 will cause the stabilizing plate 9 to slide synchronously until tray 4 is pulled out to the maximum distance. At this time, the connecting rod 5, the sliding rod 6, the straight groove 10, the T-shaped slider 8 and the T-shaped groove 7 cooperate to provide an upward pulling force on the end of tray 4 away from the detection chamber 2. Even if the glue sample to be tested is placed at this time, it will not interfere with the stability and horizontal state of tray 4 itself, thereby ensuring the relative stability of the glue sample during the pushing process and avoiding the problem of deviation in the test results caused by interference from external factors.

[0025] The bottom inner surface of the detection chamber 2 is provided with a support component, which includes a limiting groove 12. The limiting groove 12 is opened on the bottom inner surface of the tray 4. A top block 13 is fixedly installed on the bottom inner wall of the detection chamber 2. Side plates 14 are fixedly installed on both sides of the top block 13. A movable cavity 19 is opened on the inner wall of the tray 4. A lifting plate 15 is slidably installed on the inner surface of the movable cavity 19. An arc-shaped block 16 is fixedly installed on the bottom surface of the lifting plate 15. A contact rod 17 is fixedly installed on the top surface of the lifting plate 15. A wave groove 18 is opened on the top surface of the contact rod 17.

[0026] Please see Figures 4-5 The support component is located at the center of the detection chamber 2, and the top of the contact rod 17 is frosted to enhance the friction coefficient between the contact rod 17 and the container holding the glue sample, so as to avoid relative sliding between the two and affect the stability of the glue sample placed in the detection chamber 2.

[0027] The limiting groove 12 includes a rectangular groove whose size is adapted to the top block 13 and flat grooves on both sides of the rectangular groove, and the flat grooves slide with the side plate 14.

[0028] The rectangular groove design ensures that the installation of the top block 13 will not interfere with the storage and sliding of the tray 4. Furthermore, the cooperation between the flat groove and the side plate 14 further restricts the horizontal movement of the tray 4, preventing it from tipping over or tilting and affecting the stability of the glue sample placed on its surface.

[0029] The inner top wall of the tray 4 is provided with a circular hole that matches the contact rod 17, and the contact rod 17 slides in the circular hole.

[0030] The circular holes allow the lifting plate 15 to be pushed upwards by the pressure, which in turn pushes the contact rod 17 upwards. Several sets of contact rods 17 and circular holes are arranged in a circular array with the center point of the tray 4 as the center, thus forming a circular support structure at the bottom of the glue sample container. This ensures ventilation at the bottom of the glue sample container, thereby ensuring the accuracy of the equipment's detection data on energy changes within the glue.

[0031] The side of the top block 13 and the arc block 16 that are close to each other is set as an arc surface.

[0032] The curved surface between the two ensures that the upward lifting process of the top block 13 onto the curved block 16 is relatively smooth and without jamming, thus avoiding interference with the slight lifting of the glue sample container. Furthermore, as the tray 4 is pushed into the detection chamber 2 until it is completely in contact with the inner surface of the detection chamber 2, the pressure of the top block 13 on the curved block 16 causes the lifting plate 15 to move upward within the movable chamber 19, thereby lifting the multiple sets of contact rods 17 arranged in a circular array upward from the circular holes, so as to lift the container containing the glue sample placed on the upper surface of the tray 4 upward a short distance. At this time, in conjunction with the corrugated groove 18 and the frosted treatment of the top surface of the contact rods 17, the bottom of the glue sample container can maintain ventilation and heat exchange effect, while also ensuring its horizontal stability and anti-slip properties, thereby improving the accuracy of the device for glue sample detection data.

[0033] Working principle: When the container containing the glue sample is placed on the tray 4, the door 3 is opened first, and the tray 4 is pulled outward. As the tray 4 moves outward, the connecting rod 5 drives the sliding rod 6 to slide in the straight groove 10. When the sliding rod 6 slides to the end of the straight groove 10 near the door 3 and is pressed against it, continuing to pull the tray 4 will drive the stabilizing plate 9 to move outward in sync. At this time, the T-shaped slider 8 slides in the T-shaped groove 7. With the combined action of the guide components set on both sides, the tray 4 always maintains a horizontal and stable state during the extraction process. Even if a heavy glue sample is placed, it will not tilt or shake, thus ensuring the stability of the sample during the transfer process.

[0034] After the tray 4 is fully extended to its maximum position, place the glue sample container steadily on the upper surface of the tray 4, and then push the tray 4 inward to slide it back to its original position along the bottom inner surface of the detection chamber 2. During the process of the tray 4 being fully pushed into the detection chamber 2, the limiting groove 12 at the bottom of the tray 4 cooperates with the top block 13 and side plate 14 fixed at the bottom of the detection chamber 2. The side plate 14 slides with the flat grooves on both sides of the limiting groove 12 to further restrict the horizontal movement of the tray 4 and prevent it from tipping over or shifting.

[0035] Meanwhile, as the tray 4 continues to advance, the arc-shaped surface of the top block 13 gradually contacts the arc-shaped block 16 at the bottom of the lifting plate 15 and lifts it upward. The lifting plate 15 slides upward in the movable cavity 19, driving the contact rod 17 fixed on it to move upward. The top of the contact rod 17 passes through the round hole at the top of the tray 4, slightly lifting the glue sample container placed on the tray 4. The wave groove 18 at the top of the contact rod 17 and its frosted surface increase the friction with the bottom of the container, preventing the container from sliding horizontally. Multiple sets of circumferentially distributed contact rods 17 together form a stable support structure, ensuring ventilation and heat dissipation at the bottom of the container while lifting it, ensuring the uniformity of heat transfer and the accuracy of the test data.

[0036] Finally, after the tray 4 is fully reset inside the detection chamber 2, the door 3 closes, and the detection module begins to perform thermal analysis tests on the glue sample.
