Description

Technical Field

[0001] The present application relates to the technical field of quantum dots, and particularly to a device for detecting the surface viscosity of quantum dot composite particles. Background Art

[0002] Due to surface modification or coating treatment, quantum dot composite particles have viscosity. When quantum dot composite particles are used for product or device processing, they need to pass through specific processing equipment, such as a coater or an extruder. Because of their modification, their surfaces have viscosity and an affinity for the materials of the production and processing equipment. Therefore, they will adsorb and aggregate at the discharge port of the equipment at the discharge end, resulting in production material breakage. In severe cases, the equipment may be damaged due to equipment blockage, excessive torque or pressure. Therefore, it is necessary to detect and control the surface viscosity of quantum dot composite particles in different discharge environments. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a device for detecting the surface viscosity of quantum dot composite particles to solve at least one of the above problems.

[0004] A device for detecting the surface viscosity of quantum dot composite particles includes: a base, a lifting table, a detection plate, a lifting mechanism, and a material receiving device. One end of the lifting table is rotatably connected to the base, and the other end communicates with the lifting mechanism and controls the lifting of the other end of the lifting table through the lifting mechanism. The detection plate is detachably arranged on the lifting table and can rotate with the rotation of the lifting table. The material receiving device is arranged at one end of the lifting table rotatably connected to the base for receiving the quantum dot composite particles falling from the detection plate.

The other end of the first arm is rotatably connected to the lifting table, and the other end of the second arm is rotatably connected to the base.

[0007] In one embodiment, the device for detecting the surface viscosity of quantum dot composite particles further includes a controller and a control button. The controller is connected to the motor and controls the start and stop of the motor. The control button is connected to the controller for inputting a control signal to the controller.

[0023] Please refer to Figure 1 , this application provides a device for detecting the surface viscosity of quantum dot composite particles, including: a base 10, a lifting table 20, a detection plate 30, a lifting mechanism 40 and a material receiving device 50. One end of the lifting table 20 is rotatably connected to the base 10, and the other end is connected to the lifting mechanism 40 and controlled by the lifting mechanism 40 to lift the other end of the lifting table 20, so that the lifting table 20 can rotate. The detection plate 30 is detachably arranged on the lifting table 20 and can rotate with the rotation of the lifting table 20. The material receiving device 50 is arranged at one end of the lifting table 20 rotatably connected to the base 10 for receiving the quantum dot composite particles falling from the detection plate 30. The device for detecting the surface viscosity of quantum dot composite particles provided by this application can realize the lifting of one end of the lifting table 20 by setting the lifting mechanism 40, so that the lifting table 20 can rotate around the other end. When the lifting table 20 rotates, the detection plate 30 rotates accordingly. Therefore, the device for detecting the surface viscosity of quantum dot composite particles can simulate the blanking environment of quantum dot composite particles during the production and processing process. At the same time, since the detection plate 30 is detachably arranged on the lifting table 20, different detection plates 30 can be replaced to simulate the blanking environments of different processing equipment. Therefore, the surface viscosity of quantum dot composite particles in different blanking environments can be detected by using the device for detecting the surface viscosity of quantum dot composite particles, and the relevant processing process can be controlled according to the detection results, so as to reduce equipment material shortage, blockage or damage.

[0024] To better understand this solution, the usage method of the device for detecting the surface viscosity of quantum dot composite particles is briefly described as follows:

[0025] Step S1: Weigh the quantum dot composite particles, with a mass of m1;

[0026] Step S2: The lifting mechanism 40 controls the rotation of the lifting table 20 to adjust the detection plate 30 to be horizontal, that is, the angle θ between the detection plate 30 and the horizontal plane is 0°. The quantum dot composite particles are unfolded and laid flat on the detection plate 30, and left standing for a time T;

[0027] Step S3: Control the lifting table 20 to rotate around one end through the lifting mechanism 40, so that the angle θ between the detection plate 30 and the horizontal plane continuously increases, and observe the situation of the quantum dot complex particles falling off the detection plate 30. When the angle θ reaches a certain angle θ1, collect and weigh the fallen quantum dot complex particles, and record their mass as m2;

[0028] Step S4: Evaluate the surface viscosity of the quantum dot complex particles according to the following indicators: the angle θ1 between the detection plate 30 and the horizontal plane when collecting the fallen quantum dot complex particles, the surface resistance of the detection plate 30, the falling-off ratio m2 / m1 of the quantum dot complex particles, and the standing time T. Among them, the larger the θ1, the greater the surface viscosity of the quantum dot complex particles; under the same other conditions, the smaller the surface resistance of the detection plate 30, the greater the surface viscosity of the quantum dot complex particles; under the same other conditions, the larger the value of m2 / m1, the smaller the surface viscosity of the quantum dot complex particles; under the same other conditions, compare the standing time T, and the smaller the T, the greater the surface viscosity of the quantum dot complex particles.

[0029] Please refer to Figure 1 , the lifting mechanism 40 includes a lifting control arm 41 and a motor 42. The lifting control arm 41 is connected to the lifting table 20 and the base 10. The motor 42 controls the lifting of one end of the lifting table 20 by controlling the movement of the lifting control arm 41. In this way, the motor 42 controls the rotation of the lifting control arm 41 to achieve the lifting control of one end of the lifting table 20, with flexible adjustment and high control accuracy.

[0030] In this embodiment, the lifting control arm 41 includes a first arm 411 and a second arm 412. One end of the first arm 411 is rotatably connected to one end of the second arm 412. The other end of the first arm 411 is rotatably connected to the lifting table 20, and the other end of the second arm 412 is rotatably connected to the base 10. In this way, the structure of the lifting control arm 41 is simple and the control is flexible.

[0031] However, it is not limited to this. In other embodiments, the lifting control arm 41 can also be set as a telescopic arm, or other mechanisms capable of controlling lifting.

[0032] Furthermore, the quantum dot complex particle surface viscosity detection device further includes a controller 60 and a control button 70, which are connected to control the motor 42 and control the start and stop of the motor 42. The control button 70 is connected to the controller 60 and is used to input a control signal to the controller 60. In this way, by pressing the control button 70 to input a control signal and controlling the motor 42 to act through the controller 60, the lifting control of one end of the lifting table 20 is achieved.

[0033] The lifting buttons include: an up button, a down button and a stop button, so that the lifting of one end of the lifting table 20 can be controlled to rise, fall and stop respectively.

[0034] Further, the controller 60 is also connected to a timer 80. The timer 80 can be used to time the standing time of the quantum dot composite particles when the detection plate 30 is adjusted to be horizontal. The timer 80 can also be used to notify the controller 60 after reaching the set time and control the motor 42 to start through the controller 60, thereby realizing the automatic control of the motor 42.

[0035] Further, a receiving groove 21 is provided on the lifting table 20. Slide rails 22 are provided on both sides of the receiving groove 21. The detection plate 30 is arranged in the receiving groove 21, and both sides of the detection plate 30 are slidably matched with the slide rails 22. A locking device (not shown) for locking the detection plate 30 in the receiving groove 21 is also provided on the lifting table 20. In this way, by providing the receiving groove 21 and the slide rails 22, it is convenient to install the detection plate 30 on the lifting table 20. By providing the locking device to lock the detection plate 30, it can be avoided that the detection plate 30 falls off when the lifting table 20 rotates around one end, thereby ensuring the consistency of the movement of the detection plate 30 and the lifting table 20. Different detection plates 30 can be replaced after unlocking. In this embodiment, the locking device can be set as a bolt. Passing the bolt through the lifting table 20 and the detection plate 30 can lock the detection plate 30 on the lifting table 20. The structure is very simple, and locking and unlocking are very convenient.

[0036] When producing products or processing devices with quantum dot composite particles, different processing steps will use different processing equipment. The material of the detection plate 30 is preferably the same as or similar to that of the processing equipment. Specifically, the detection plate 30 is a stainless steel plate, a nickel-plated plate, an aluminum alloy plate, a PE plate, a PP plate, a PVC plate or an aluminum foil plate. In this way, the material of the detection plate 30 is the same as or similar to that of most processing equipment, so that the detection plate 30 can simulate different processing environments.

[0037] Further, the surface of the detection plate 30 for carrying the quantum dot composite particles is engraved with concave and convex patterns. Since the processing equipment will have a certain amount of wear and generate patterns during use, in this embodiment, by engraving concave and convex patterns on the surface of the detection plate 30 for carrying the quantum dot composite particles, the actual production and processing environment can be simulated, that is, the patterns generated by the wear of the processing equipment are simulated. Thus, the production and processing process of the quantum dot composite particles can be better controlled according to the viscosity detected by the quantum dot composite particle surface viscosity detection device.

[0038] Further, a coating is provided on the surface of the detection plate 30 for carrying the quantum dot composite particles. The coating is a fluorine coating, a wear-resistant material coating or a paraffin coating. Since in actual production and processing equipment, fluorine coatings, wear-resistant material coatings or paraffin coatings are provided on the inner walls of some parts, therefore, in this embodiment, setting the coating can simulate the actual production and processing environment, so that the production and processing process of the quantum dot composite particles can be better controlled according to the viscosity detected by the quantum dot composite particle surface viscosity detection device.

[0039] In this application, the detection plate 30 carries quantum dot composite particles on its upper surface.

[0040] Furthermore, a constant temperature device (not shown) for keeping the detection plate 30 in a constant temperature environment is also provided on the lifting platform 20. In this way, a processing device that can simulate a constant temperature environment can be obtained, so that it is the same as or close to the actual production and processing situation, making the detection result more instructive. In this embodiment, the temperature control range of the constant temperature device is: 0°C to 250°C, that is, the constant temperature device can control the temperature of the detection plate 30 within any temperature in the range of 0°C to 250°C.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0042] The above-described embodiments only represent several implementation manners of this application, and their descriptions are relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the patent protection scope of this application should be subject to the appended claims.
