Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of glass density detection, and in particular to a density detector. Background Art
[0002] At present, the density of optoelectronic display substrate glass in China is tested by inspectors in most cases cutting the glass, then weighing it with a glass density meter and calculating the final result.
[0003] Specifically, a glass densitometer generally includes a water tank for loading ultrapure water and a bracket partially placed in the water tank. The detection process generally includes the following steps: first calibrate the peeling, at which time the reading of the balance is 0, then place the glass on the bracket, and record the mass of the glass in the air (m1) after the reading stabilizes. Use tweezers to clamp the glass and place it in the ultrapure water of the densitometer for measurement, ensuring that the glass does not touch the wall of the container. After the liquid stabilizes, record the mass of the glass in the liquid (m2). Finally, perform data processing: enter or confirm the liquid density (ρ 液 ), the internal software of the instrument automatically calculates the volume of the glass (V = (m1-m2) / ρ 液 ) and density (ρ 玻璃 =m1 / V).
[0004] However, there are two problems with traditional density meters: First, when testing the density of glass, when using tweezers to hold the glass and put it into the ultrapure water measurement of the density meter, the tweezers may not be able to hold it firmly, causing the glass to fall into the ultrapure water, which in turn causes the ultrapure water to splash out. The splashing of ultrapure water means that the sample glass did not completely displace the original part of the water when entering the water, and the actual volume of water displaced was reduced. Correspondingly, the buoyancy it received would also be reduced, which would affect the measurement result of the mass of the glass in the liquid (m2), resulting in inaccurate results. Second, because the glass is constantly put in and out of the ultrapure water with tweezers, the impurities in the tweezers will affect the purity of the ultrapure water, and the density of the ultrapure water changes at a certain temperature, which in turn causes inaccurate measurement of the glass density. Utility Model Content
[0005] A technical problem to be solved by the present disclosure is: how to avoid the problem of ultrapure water splashing out and the introduction of tweezer impurities during the process of placing glass into the water of the density meter for measurement, thereby improving the accuracy of the glass density measurement result.

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0035] Existing glass densitometers generally include a water tank for loading ultrapure water and a bracket partially placed in the water tank. The detection process generally includes the following steps: first calibrate the peeling, at which time the balance reading is 0, then place the glass on the balance pan, close the wind shield, and record the mass of the glass in the air (m1) after the reading stabilizes. Use tweezers to pick up the glass and place it on the tray of the bracket in the ultrapure water of the densitometer for measurement, ensuring that the glass does not touch the container wall. After the liquid stabilizes, record the mass of the glass in the liquid (m2). Finally, perform data processing: enter or confirm the liquid density (ρ 液 ), the internal software of the instrument automatically calculates the volume of the glass (V = (m1-m2) / ρ 液 ) and density (ρ 玻璃 =m1 / V).
[0036] However, there are two problems with traditional density meters: First, when testing the density of glass, when using tweezers to hold the glass and put it into the ultrapure water measurement of the density meter, the tweezers may not be able to hold it firmly, causing the glass to fall into the ultrapure water, which in turn causes the ultrapure water to splash out. The splashing of ultrapure water means that the sample glass did not completely displace the original part of the water when entering the water, and the actual volume of water displaced was reduced. Correspondingly, the buoyancy it received would also be reduced, which would affect the measurement result of the mass of the glass in the liquid (m2), resulting in inaccurate results. Second, because the glass is constantly put in and out of the ultrapure water with tweezers, the impurities in the tweezers will affect the purity of the ultrapure water, and the density of the ultrapure water changes at a certain temperature, which in turn causes inaccurate measurement of the glass density.
[0037] To solve the above technical problems, an embodiment of the present disclosure provides a density detector, which can avoid the problem of ultrapure water splashing and introduction of tweezers impurities when placing glass into the density meter water for measurement, thereby improving the accuracy of the glass density measurement results.
[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a density detector includes a bracket 1 and a water tank 2, and also includes a traction mechanism 3, the traction mechanism 3 is installed on the bracket 1, the traction mechanism 3 includes a traction rope 32 and a driving part 31, the driving part 31 is connected to the first end of the traction rope 32, the second end of the traction rope 32 is connected to the bearing mechanism 4, and the bearing mechanism 4 is arranged in the vertical space corresponding to the bottom of the water tank 2; wherein the driving part 31 is connected to the controller, and the controller can control the driving part 31 to drive the second end of the traction rope 32 to move up and down and then drive the bearing mechanism 4 to move up and down between a first position and a second position, the first position is located below the liquid level of the water tank 2, and the second position is located above the liquid level of the water tank 2.
[0039] Specifically, the support 1 is a supporting structure that ensures that the object to be tested is completely immersed in the liquid and does not contact the container wall of the water tank 2. Figure 1As shown, it may include a horizontal rectangular frame surrounding the water tank 2 and a vertical gate-shaped support frame arranged outside the water tank 2, the gate-shaped support frame is installed on the rectangular frame, and the traction mechanism 3 is installed on the gate-shaped support frame; the bracket 1 may also include a hollow shell wrapped around the outside of the water tank 2 and a tray arranged in the water tank 2, the tray is connected to the hollow shell and the hollow shell does not contact the container wall of the water tank 2; at this time, the traction mechanism 3 is installed on the top of the hollow shell. When in use, first peel off the weight of the bracket 1 and the traction mechanism 3 connected to the bracket 1 and the bearing mechanism 4 in the first position, and when the reading of the floor is zero, place the object on the bracket 1 to measure its mass in the air and its mass in ultrapure water. As long as the bracket 1 can ensure that the object to be tested is completely immersed in the liquid and does not contact the container wall of the water tank 2, the specific type of the bracket 1 can be selected in the prior art according to actual conditions, and the type and structure of the bracket 1 are not specifically limited.
[0040] The water tank 2 is a container for carrying ultrapure water or other liquids of known density (such as water or alcohol); specifically, the water tank 2 can be a square tank or a circular tank; as long as the water tank 2 can carry ultrapure water or other liquids of known density, there is no specific limitation on the shape and structure of the water tank 2.
[0041] The traction mechanism 3 is a device for traction and carrying mechanism 4 to move up and down. Specifically, the traction mechanism 3 can be a structure in which a pulley and a traction rope 32 are matched; it can also be a structure in which a hydraulic cylinder, a cylinder and a traction rope 32 are matched. As long as the traction mechanism 3 can drive the carrying mechanism 4 to move up and down, the body structure and type of the traction mechanism 3 are not limited. Correspondingly, the driving part 31 is a mechanism in the traction mechanism 3 for driving the second end of the traction rope 32 to move up and down; specifically, the driving part 31 can be a combination of a motor 311 and a single pulley, that is, the pulley can be set at the top of the bracket 1, the motor 311 is connected to the pulley, and the pulley is driven to rotate so as to drive the second end of the traction rope 32 to move up and down; it can also be a combination of a motor 311 and multiple pulleys, or it can be other driving devices such as a hydraulic cylinder and a cylinder. As long as the driving part 31 can drive the second end of the traction rope 32 to move up and down, thereby driving the carrying mechanism 4 to move up and down, the specific structure of the driving part 31 is not limited.
[0042] The carrying mechanism 4 is a device for carrying the object to be tested. Specifically, the carrying mechanism 4 can be a combination of multiple connecting ropes 421 and a plate-like structure, or a combination of two mutually connected parallel plate-like structures. As long as the carrying mechanism 4 can cooperate with the traction rope 32 to carry the object to be tested and move up and down, there is no specific limitation on the structure of the carrying mechanism 4.
[0043] The controller is a device that can control the driving unit 31 to drive the second end of the traction rope 32 to move up and down, thereby driving the carrying mechanism 4 to move up and down between the first position and the second position. Specifically, the controller can be a PLC (programmable logic controller) and a PAC (programmable automation controller) and other types of controllers. As long as the controller can control the driving unit 31 to drive the second end of the traction rope 32 to move up and down, thereby driving the carrying mechanism 4 to move up and down between the first position and the second position, the specific type of the controller is not limited. More specifically, the controller can be connected to the rising button 61 and the falling button 62, so as to facilitate the control of the carrying mechanism 4 to move up and down between the first position and the second position. The rising button 61 and the falling button 62 can be set on the base 6 of the density detector.
[0044] Specifically, the density detector may further include a windshield 5, which is sleeved on the outside of the bracket 1 and the water tank 2 to prevent wind from affecting the measurement results. The traction rope 32 is a rope used to pull the supporting mechanism 4 up and down. Specifically, in order to prevent the traction rope 32 from absorbing water and reducing the accuracy of the measurement results, the traction rope 32 can be made of a hydrophobic material. For example, the material of the traction rope 32 can be made of synthetic fibers, modified natural fibers, and mixed fibers; a hydrophobic coating can also be provided on the surface of the traction rope 32 to improve the hydrophobicity of the traction rope 32. As long as the traction rope 32 can pull the supporting mechanism 4 up and down, the specific structure of the traction rope 32 is not limited. Similarly, the supporting mechanism 4 can also be made of a hydrophobic material.
[0045] When in use, first immerse the supporting mechanism 4 into the liquid surface of the water tank 2 so that the supporting mechanism 4 is in the first position, then calibrate and peel, at this time the reading of the balance is 0, then place the glass or other object to be tested on the bracket 1, and record the reading of the balance after the reading stabilizes, which is the mass of the glass in the air (m1). The controller controls the supporting mechanism 4 to rise, so that the supporting mechanism 4 moves from the first position below the liquid surface of the water tank to the second position above the liquid surface of the water tank. After the staff wears gloves and directly places the glass on the supporting mechanism 4, the controller controls the supporting mechanism 4 to descend to the first position, during this process ensuring that the glass does not contact the container wall. After the liquid is stable, record the reading of the balance, which is the mass of the object to be tested in the liquid (m2). Finally, perform data processing: input or confirm the liquid density (ρ 液 ), the internal software of the instrument automatically calculates the volume of the object to be measured (V = (m1-m2) / ρ 液 ) and density (ρ 待测物 =m1 / V).
[0046] Through the above technical solution, the density detector provided by the present disclosure is provided with a traction mechanism 3, and the traction rope 32 of the traction mechanism 3 is connected to the bearing mechanism 4 for bearing the object to be measured, so that the traction rope 32 can drive the bearing mechanism 4 to move up and down smoothly between the second position above the liquid level of the water tank 2 and the first position below the liquid level of the water tank 2, so that the staff can directly place the glass on the bearing mechanism 4 with gloves and drive the glass to slowly immerse into the ultrapure water of the density detector, thereby replacing tweezers to put the glass into the water of the density meter for measurement, avoiding the problem of ultrapure water splashing and introducing tweezers impurities, and improving the accuracy of the glass density measurement results. In addition, in order to avoid the introduction of the bearing part and the traction part to affect the measurement result, the present application connects the driving part 31 to the controller. When calibrating the peeling before measurement, the controller can be used to make the position of the bearing plate 41 at this time the same as its position when measuring the mass in the sample water, that is, both are in the first position, thereby avoiding the introduction of the bearing part and the traction part to affect the measurement result.
[0047] In some embodiments, the second end of the traction rope 32 is arranged at a position corresponding to the central area of the bottom of the water tank 2. The second end of the traction rope 32 is arranged at a position corresponding to the central area of the bottom of the water tank 2, so that the supporting mechanism 4 is located at a position corresponding to the central area of the bottom of the water tank 2, thereby avoiding the supporting mechanism 4 from not contacting the inner wall of the water tank 2 during the movement process and in the first position, thereby improving the accuracy of the measurement.
[0048] In some embodiments, the carrying mechanism 4 includes a carrying plate 41 and a connecting portion 42 . The carrying plate 41 is connected to the traction rope 32 via the connecting portion 42 , and the carrying plate 41 is in a horizontal position.
[0049] The carrying plate 41 is a plate-like structure used to carry the object to be tested and sink it into the liquid. Specifically, the carrying plate 41 can be a rectangular plate, a circular plate, or other polygonal plates. More specifically, in order to prevent the carrying plate 41 from floating on the surface of the liquid, the carrying plate 41 can be made of a hydrophobic material with a relatively high density, for example, stainless steel and other metal-based composite materials can be selected. As long as the carrying plate 41 can carry the object to be tested and immerse it in a liquid of known density, the specific structure and material of the carrying plate 41 are not limited.
[0050] like Figure 6 As shown, the connection part 42 is a structure for connecting the traction rope 32 and the load-bearing plate 41; specifically, the connection part 42 can be a plurality of ropes, connected to the traction rope 32 at the center of the load-bearing plate 41 through the plurality of ropes; it can also be a combination of a support plate 422 and a connection rope 421, or it can be a combination of a support plate 422 and a plurality of connection rods. As long as the connection part 42 can connect the traction rope 32 and the load-bearing plate 41 together, the specific structure of the connection part 42 is not limited.
[0051] By setting up a structure that cooperates with the supporting plate 41 and the connecting portion 42, on the one hand, the supported object can be kept horizontal during transportation to prevent the object to be tested from falling during transportation; on the other hand, the plate-like structure is easier to immerse in the liquid than the groove-like structure, which prevents the object to be tested from falling during transportation while ensuring that the supporting plate 41 can be completely immersed in the liquid with the object to be tested.
[0052] In some embodiments, the connecting portion 42 includes a support plate 422 and a connecting rope 421, the support plate 422 is parallel to the load-bearing plate 41, and the support plate 422 and the load-bearing plate 41 are connected by a plurality of connecting ropes 421. By providing the support plate 422 and the plurality of connecting ropes 421 connected to the load-bearing plate 41, a frame structure can be formed to ensure that the load-bearing plate 41 remains horizontal during transportation. Similarly, in order to further ensure the accuracy of the measurement results, the connecting rope 421 can be made of the same hydrophobic material as the traction rope 32, and the support plate 422 can also be made of the same hydrophobic material as the load-bearing plate 41.
[0053] In some embodiments, the connecting portion 42 includes a support plate 422 and a connecting rod, the support plate 422 is parallel to the carrying plate 41, and the support plate 422 and the carrying plate 41 are connected by a plurality of connecting rods. The supporting plate 422 and the carrying plate 41 are formed into a more stable frame structure by the connecting rods, thereby preventing the carrying plate 41 from deflecting in the liquid, and further ensuring stability during transportation. Specifically, the connecting rods can be connected to the four corners of the carrying plate 41 and the support plate 422.
[0054] In some embodiments, four connecting ropes 421 are provided, and the four connecting ropes 421 are respectively connected to the four corners of the carrying plate 41 and the support plate 422. By connecting the carrying plate 41 and the support plate 422 together at the four corners of the carrying plate 41 and the support plate 422, the stability of the connection between the carrying plate 41 and the support plate 422 is improved, and the carrying plate 41 is prevented from tilting during transportation.
[0055] like Figure 5 and Figure 6 As shown, the driving part 31 includes a motor 311, a first pulley 312 and a second pulley 313. The traction rope 32 is wound around the first pulley 312. The motor 311 is connected to the first pulley 312 and can drive the first pulley 312 to rotate. The first pulley 312 is arranged on the side wall of the bracket 1, and the second pulley 313 is arranged on the top of the bracket 1. The traction rope 32 passes around the second pulley 313 and is connected to the supporting mechanism 4.
[0056] Specifically, the first pulley 312 and the second pulley 313 can be installed on the corresponding positions of the bracket 1 of the density detector through the pulley bracket 33; the motor 311 that drives the first pulley 312 can be a slow motor or a servo motor 311; the combination of the two pulleys and the motor 311 can further ensure the stability of the supporting mechanism 4 when it moves up and down, and it is also convenient to control the supporting mechanism 4 to accurately reach the first position and the second position.
[0057] In some embodiments, the driving part 31 is a hydraulic cylinder, and the traction rope 32 is connected to the movable end of the driving part 31. The hydraulic cylinder can be used to drive the traction rope 32 to move up and down.
[0058] In some embodiments, the hydraulic cylinder is disposed directly above the supporting mechanism 4. Placing the hydraulic cylinder directly above the supporting mechanism 4 can prevent the supporting mechanism 4 from contacting the inner wall of the water tank 2 during transportation, thereby improving the accuracy of the measurement result.
[0059] In some embodiments, a mark is provided on the traction rope 32. When the carrying mechanism 4 is in the first position, the mark is at the position of the liquid surface of the water tank 2 or other positions that are easy to calibrate, so as to calibrate the position of the carrying mechanism 4 and improve the accuracy of the measurement result.
