Description

Technical Field

[0001] The present invention relates to the technical field of glass measuring tool verification, and specifically to a verification device and method for common glass measuring tools in a laboratory. Background Art

[0002] Glass measuring tools are instruments used to measure the volume or mass of liquids. Common ones include graduated cylinders, measuring cups, volumetric flasks, burettes, etc. The verification of glass measuring tools is an important link to ensure their measurement accuracy and reliability.

[0003] When verifying a glass measuring tool, it is necessary to first clean the glass measuring tool to remove surface impurities, then dry it so that there is no residue inside the glass measuring tool, then inject pure water into the glass measuring tool, then weigh the total mass of the measuring tool and the water, calculate the difference between the two, finally obtain the mass of the water, and then calculate the actual capacity of the glass measuring tool according to the density value.

[0004] In the prior art, when a laboratory verifies a glass measuring tool, it is generally verified by on-site staff. According to the provisions in JJG196 - 2006 "Verification Regulation for Common Glass Measuring Instruments", the detection temperature should be within the range of (20 ± 5) °C, and the temperature change during the verification process cannot exceed 1 °C. When the staff is performing the detection, they hold the glass measuring tool throughout the process, and the hand temperature is generally about 33 °C - 35 °C. When holding the glass measuring tool for a long time, it will cause the glass measuring tool to heat up, thus affecting the later verification results. At the same time, cleaning and drying are also required during the verification process, and the glass measuring tool needs to be manipulated all the time during the operation, which will inevitably cause damage to the glass measuring tool, thus affecting the verification of the glass measuring tool.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figure 1 - Figure 9 As shown, the present application provides an inspection device for commonly used glass measuring tools in a laboratory, including a mobile base 1; the side wall of the mobile base 1 is rotatably connected to a mobile lead screw 11; the mobile lead screw 11 is threadedly connected to a mobile block 13; the side wall of the mobile block 13 is fixedly connected to a rotating motor 14; one end of the rotating motor 14 away from the mobile block 13 is rotatably connected to a connecting shaft 15, and it is characterized in that it further includes:

[0041] A fixing mechanism 2, arranged in the mobile base 1;

[0042] A cleaning mechanism 3, arranged above the mobile base 1;

[0043] A drying mechanism 4, arranged on one side of the cleaning mechanism 3;

[0044] The fixing mechanism 2 includes a fixing bin 21; one end of the connecting shaft 15 away from the mobile block 13 is fixedly connected to the fixing bin 21; the fixing bin 21 is slidably arranged in the mobile base 1;

[0045] A driven box 16 is fixedly connected to the bottom of the moving base 1; a tooth 161 is fixedly connected to the side wall of the driven box 16; the teeth 161 are arranged intermittently.

[0046] During operation, in the prior art, when the laboratory calibrates glass measuring tools, it is generally calibrated by on-site staff. According to the provisions of JJG196-2006 "Verification Regulation of Common Glass Measuring Instruments", the detection temperature should be within the range of (20±5)°C, and the temperature change during the verification process cannot exceed 1°C. When the staff conducts the detection, they hold the glass measuring tool throughout the process, and the hand temperature is generally about 33°C - 35°C. When holding the glass measuring tool for a long time, the glass measuring tool will heat up, thus affecting the subsequent verification results. At the same time, during the verification process, cleaning and drying are also required. When operating, the glass measuring tool needs to be manipulated all the time, which will inevitably cause damage to the glass measuring tool, thus affecting the verification of the glass measuring tool. To prevent such incidents from occurring, first, place the glass measuring tool on the fixed bin 21, then drive the moving screw 11 to rotate. When rotating, use the moving block 13 to drive the fixed bin 21 to move. While moving, the glass measuring tool will be clamped and fixed, and at the same time, it will reach the cleaning mechanism 3 for cleaning work. After the cleaning work is completed, use the rotating motor 14 to drive the connecting shaft 15 to rotate, and then drive the fixed bin 21 to rotate to pour out the cleaning water in the glass measuring tool. Then move it to the drying mechanism 4 for drying work. When drying, the glass measuring tool is not clamped, which can avoid the clamped part being in a wet state. After drying, drive the fixed bin 21 to move again. When moving out of the drying bin 41, clamp the glass measuring tool again, then pour pure water into the glass measuring tool, and finally cancel the clamping, take out the glass measuring tool and weigh it to obtain the verification result. Through the settings of the moving base 1 and the fixed bin 21, the contact time between the hand and the glass measuring tool during verification is greatly reduced, effectively preventing the glass measuring tool from heating up, and assisting the staff to realize the verification of the glass measuring tool. And according to the settings of the cleaning mechanism 3 and the drying mechanism 4, the cleaning and drying work can be quickly realized, improving the verification efficiency.

[0047] Such as Figure 2 - Figure 9As shown, a middle plate 23 is fixedly connected to the side wall of the fixed bin 21; both side walls of the middle plate 23 are rotatably connected with a bidirectional lead screw 24; one end of the bidirectional lead screw 24 away from the middle plate 23 is rotatably connected to the side wall of the fixed bin 21; a back plate 25 is threadedly connected to the bidirectional lead screw 24; a sliding groove 211 is formed at the top of the fixed bin 21; the back plate 25 is arranged through the sliding groove 211; a clamping spring 252 is fixedly connected to the side wall of the back plate 25; one end of the clamping spring 252 away from the back plate 25 is fixedly connected to a clamping plate 253; a limiting plate 26 is sleeved on the bidirectional lead screw 24; a limiting frame 261 is fixedly connected to the side wall of the limiting plate 26; the back plate 25 is arranged inside the limiting frame 261; a clamping block 262 is fixedly connected to the side wall of the limiting plate 26; the clamping block 262 is arranged through the fixed bin 21; a clamping groove 2621 is formed inside the clamping block 262; a clamping spring 2622 is fixedly connected inside the clamping groove 2621; one end of the clamping spring 2622 away from the clamping block 262 is fixedly connected to a clamping head 2623; an adjusting bin 27 is fixedly connected to the side wall of the fixed bin 21; there are three groups of the adjusting bins 27 and they are arranged at equal intervals; the clamping head 2623 is clamped inside the adjusting bin 27; one end of the clamping head 2623 away from the adjusting bin 27 is fixedly connected to a pull rod 2624; the pull rod 2624 is arranged through the clamping block 262; there are two groups of adjusting blocks, which are respectively arranged on both sides of the limiting plate 26; a crown gear 22 is rotatably connected to the bottom of the fixed bin 21; a driven gear 241 is fixedly connected to the bidirectional lead screw 24; the driven gear 241 is meshed with the crown gear 22; a driving column 29 is rotatably connected to the bottom of the fixed bin 21; the output end of the driving column 29 is fixedly connected to the input end of the crown gear 22; one end of the driving column 29 away from the fixed bin 21 is fixedly connected to a driving gear 292; the driving gear 292 is movably meshed with the tooth 161; a hexagonal sleeve 291 is fixedly connected to the driving column 29;

[0048] During operation, there are many sizes of glass containers. The glass measuring tools that can be clamped by the fixed bin 21 are divided into three sizes: large, medium, and small. The size cannot be greater than the outer diameter of the fixed bin 21, nor can it be a thin-tube measuring tool, otherwise it will affect the clamping effect. After determining the measuring tool to be calibrated, move the pull rod 2624 on the fixed bin 21. Use the pull rod 2624 to drive the clamping blocks 262 on both sides to move. At the same time, use the clamping blocks 262 to drive the limit plate 26 to move. When moving, the clamping blocks 262 can be moved above the adjustment bin 27. There are three groups of adjustment bins 27, corresponding to the large, medium, and small sizes respectively. Move the clamping blocks 262 as needed. When moving, the clamping head 2623 is squeezed back into the clamping block 262 by the adjustment bin 27. When it moves above the appropriate adjustment bin 27, since the adjustment bin 27 is hollow, the clamping spring 2622 will rebound and pop the clamping head 2623 into the adjustment bin 27, thus achieving the fixing effect and at the same time moving the limit frame 261 on the limit plate 26 to the appropriate range of the glass measuring tool. Then place the glass measuring tool on the fixed bin 21 and drive the moving lead screw 11 to rotate to drive the fixed bin 21 to move. When the fixed bin 21 moves, it will drive the lower drive column 29 and the drive gear 292 to move. When the drive gear 292 moves, it will contact the teeth 161 in the driven box 16. The teeth 161 are arranged discontinuously, that is, there are no teeth 161 directly below the cleaning mechanism 3, nor at the front end of the moving base 1. This facilitates the adjustment of the fixed bin 21. After the drive gear 292 meshes with the teeth 161, it continues to move and is driven to rotate by the teeth 161 during movement, thereby driving the crown gear 22 inside the fixed bin 21 to rotate. Then, through two driven gears 241, the bidirectional lead screw 24 is driven to rotate, and then two back plates 25 are driven to move towards the glass measuring tool. Among them, the movement of the back plate 25 is carried out within the limit frame 261. During the movement, the clamping plate 253 will gradually approach the glass measuring tool and clamp it. After clamping, if the fixed bin 21 has not reached the toothless part of the driven box 16, the bottom plate 251 will squeeze the clamping spring 252. At the same time, through the setting of the clamping spring 252, it can be avoided that the clamping plate 253 has hard contact with the glass measuring tool during continuous clamping, thus damaging the glass measuring tool. Until the drive gear 292 disengages from the teeth 161, after disengagement, the fixed bin 21 enters the cleaning mechanism 3 for cleaning. After cleaning, rotate the motor 14 to drive the connecting shaft 15 to rotate, thereby driving the fixed bin 21 to rotate, so that the cleaning water in the glass measuring tool is poured out. After pouring out, it returns to its original position. And when rotating, the drive gear 292 and the teeth 161 are in a non-meshing state, so it will not affect the rotation. After pouring out, drive the fixed bin 21 to reach the drying mechanism 4. Since the fixed bin 21 is continuously moving, continuous pressure will be applied to the glass measuring tool during continuous movement. The bidirectional lead screw 24 is a ball screw, and the limit frame 261 sets a turning point for the back plate 25. When the back plate 25 contacts the limit frame 261, the back plate 25 will exhibit a turning behavior, thereby releasing the pressure. When the fixed bin 21 reaches the drying mechanism 4,The clamping plate 253 has cancelled the fixation of the glass measuring tool to avoid drying during the clamping process, which may cause the phenomenon of non-dried areas at the clamping points. After the drying is completed, the fixed bin 21 is driven to move again. During this movement, the back plate 25 will be blocked by the limit frame 261 and turn back, thus clamping the glass measuring tool again. After this clamping, the staff manually pours pure water into the glass measuring tool. After pouring, the fixation of the glass measuring tool is cancelled, and the glass measuring tool can be taken out and weighed. When it is necessary to calibrate another group of glass measuring tools with different sizes, the staff can pull the pull rod 2624, which drives the clamping joint 2623 to rise by means of the pull rod 2624, so that the clamping joint 2623 cancels the clamping connection with the adjustment bin 27, and then the clamping block 262 can be moved. Through the setting of the limit frame 261 and the adjustment bin 27, glass measuring tools of different sizes can be fixed, and the hard contact between the clamping plate 253 and the glass measuring tool can be avoided through the cooperation of the limit frame 261 and the tooth 161. When adjusting the limit frame 261, since the back plate 25 is inside the limit frame 261, the position of the back plate 25 needs to be adjusted first. When adjusting, the fixed bin 21 is moved to the place where the tooth 161 is not set, and then the hexagonal sleeve 291 is rotated to drive the driving column 29 to rotate, thereby adjusting the two groups of back plates 25.,

[0050] During operation, after the fixed bin 21 reaches the cleaning bin 31, the long spray pipe 34 is used to inject water into the glass measuring tool for cleaning, and the side spray pipes 33 clean both sides of the glass measuring tool.

[0051] As Figure 2 shown, the drying mechanism 4 includes a drying bin 41; a fan shaft 43 is rotatably connected to the top of the drying bin 41; a wind blade 44 is fixedly connected to the fan shaft 43; a drying motor 42 is fixedly connected to the outside of the drying bin 41; the fan shaft 43 is driven by the drying motor 42; door curtains 5 are arranged at both ends of the drying bin 41;

[0052] During operation, after the water in the glass measuring tool is poured out after cleaning, the fixed bin 21 is driven to move into the drying bin 41, and at the same time, the fixation is cancelled for drying work. After completion, the fixed bin 21 is moved out of the drying bin 41, and then pure water is injected into the glass measuring tool and then calibrated. And through the setting of the door curtain 5, the spraying of cleaning water can be avoided.

[0053] As Figure 7As shown, a water outlet hole 162 is provided at the bottom of the driven box 16; a diversion groove 18 is provided at the bottom of the moving base 1; the diversion groove 18 is arranged on both sides of the driven box 16; a water collecting bin 17 is slidably connected to the bottom of the moving base 1;

[0054] During operation, when pouring water, the cleaning water will fall below the moving base 1, and the cleaning water can be introduced into the water collecting bin 17 through the water outlet hole 162 and the diversion groove 18 for collection.

[0055] As Figure 2 shown, a moving motor 12 is fixedly connected to the side wall of the moving base 1; the moving lead screw 11 is driven by the moving motor 12; both the crown gear 22 and the driven gear 241 are arranged as bevel gears;

[0056] During operation, the moving lead screw 11 is driven by the moving motor 12, and the bevel gears can better achieve meshing.

[0057] As Figure 3 shown, a limiting block 19 is slidably connected to the side wall of the moving base 1; one end of the limiting block 19 away from the moving base 1 is rotatably connected to the fixed bin 21; a telescopic plate 28 is fixedly connected to the side wall of the middle plate 23; the telescopic plate 28 is arranged in the chute 211; one end of the telescopic plate 28 away from the middle plate 23 is fixedly connected to the back plate 25;

[0058] During operation, one end of the fixed bin 21 away from the connecting shaft 15 is connected to the limiting block 19 and limited by the limiting block 19. At the same time, the chute 211 of the fixed bin 21 is closed by the telescopic plate 28 to prevent the cleaning water from entering the fixed bin 21, and the telescopic plate 28 can be changed as the back plate 25 moves.

[0059] Please refer to Figure 1 - Figure 9 shown, the present application provides a verification method for commonly used glass measuring tools in laboratories, including the following steps:

[0060] S1. First, adjust the position of the limiting frame 261 on the bidirectional lead screw 24 according to the size of the glass measuring tool to be verified. After adjustment, damage to the glass measuring tool by the clamping plate 253 can be avoided. Then, place the glass measuring tool on the fixed bin 21, and then move the fixed bin 21 to clamp and fix the glass measuring tool by using the clamping plate 253;

[0061] S2. Move the fixed bin 21 into the cleaning bin 31. When reaching the cleaning bin 31, the glass measuring tool is clamped and fixed. Then, inject cleaning water into the inside of the glass measuring tool for cleaning by using the long nozzle, and the outside is cleaned by the side spray pipes 33 on both sides. After cleaning, drive the fixed bin 21 to rotate by using the rotating motor 14 to pour out the cleaning water in the glass measuring tool, and then drive the fixed bin 21 to move to the drying mechanism 4;

[0062] In step S3, after reaching the inside of the drying bin 41, start the rotation of the blower shaft 43. The glass measuring tool can be quickly dried by using the blower blades 44. Finally, drive the fixed bin 21 out of the drying bin 41, pour pure water into the glass measuring tool and then weigh it for verification.

[0063] During operation, first, adjust the position of the limit frame 261 on the bidirectional lead screw 24 according to the size of the glass measuring tool to be verified. After adjustment, damage to the glass measuring tool by the clamping plate 253 can be avoided. Then, place the glass measuring tool on the fixed bin 21. Subsequently, move the fixed bin 21, and use the clamping plate 253 to clamp and fix the glass measuring tool. Move the fixed bin 21 into the cleaning bin 31. When reaching the cleaning bin 31, the glass measuring tool is clamped and fixed. Then, inject cleaning water into the inside of the glass measuring tool for cleaning by using the long nozzle, and the outside is cleaned by the side spray pipes 33 on both sides. After cleaning, drive the fixed bin 21 to rotate by using the rotation motor 14 to pour out the cleaning water in the glass measuring tool. Subsequently, drive the fixed bin 21 to move to the drying mechanism 4. After reaching the inside of the drying bin 41, start the rotation of the blower shaft 43. The glass measuring tool can be quickly dried by using the blower blades 44. Finally, drive the fixed bin 21 out of the drying bin 41, pour pure water into the glass measuring tool and then weigh it for verification.

[0064] Working principle of the present invention: After determining the measuring tool to be calibrated, pull the pull rod 2624 on the fixed bin 21, drive the clamping blocks 262 on both sides by the pull rod 2624, and at the same time drive the limiting plate 26 by the clamping blocks 262. When moving, the clamping blocks 262 can be moved above the adjustment bin 27. There are three groups of adjustment bins 27, corresponding to large, medium and small sizes respectively. Move the clamping blocks 262 according to needs. When moving, the clamping head 2623 is squeezed back into the clamping block 262 by the adjustment bin 27. When moving above the appropriate adjustment bin 27, since the adjustment bin 27 is hollow, the clamping spring 2622 will rebound and eject the clamping head 2623 into the adjustment bin 27, so as to achieve the fixing effect, and at the same time move the limiting frame 261 on the limiting plate 26 to the range of the appropriate glass measuring tool. Then place the glass measuring tool on the fixed bin 21, and drive the moving lead screw 11 to rotate to drive the fixed bin 21 to move. When the fixed bin 21 moves, it will drive the lower driving column 29 and the driving gear 292 to move. When the driving gear 292 moves, it will contact the teeth 161 in the driven box 16. The teeth 161 are arranged intermittently, that is, no teeth 161 are provided directly below the cleaning mechanism 3, and no teeth 161 are provided at the front end of the moving base 1 either. This is convenient for adjusting the fixed bin 21. After the driving gear 292 meshes with the teeth 161, it continues to move and is driven to rotate by the teeth 161 when moving, so as to drive the crown gear 22 inside the fixed bin 21 to rotate, and then drive the bidirectional lead screw 24 to rotate through the two driven gears 241, and further drive the two back plates 25 to move towards the glass measuring tool. Among them, the movement of the back plate 25 is carried out within the limiting frame 261. During the movement, the clamping plate 253 will gradually approach the glass measuring tool and clamp it. After clamping, if the fixed bin 21 has not reached the toothless part of the driven box 16, the bottom plate 251 will squeeze the clamping spring 252. At the same time, through the setting of the clamping spring 252, it can be avoided that the clamping plate 253 has hard contact with the glass measuring tool during continuous clamping, thereby damaging the glass measuring tool, until the driving gear 292 disengages from the teeth 161. After disengaging, the fixed bin 21 enters the cleaning mechanism 3 for cleaning.
