Description

Technical Field

[0001] This application relates to an antistatic device. Background Technology

[0002] Volumetric flasks are common instruments in medical experiments. These flasks are prone to generating static electricity during use. This static electricity not only affects experimental results but also greatly increases the probability of fire if excessive. To remove static electricity, researchers usually place each volumetric flask individually on a small static eliminator for air blowing. However, the air blowing direction of this small static eliminator is relatively fixed, requiring researchers to constantly adjust the angle or direction of the volumetric flasks during the blowing process. This not only increases the labor intensity of researchers but also reduces work efficiency and does not guarantee the effectiveness of static removal. Summary of the Invention

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Example

[0027] To address the problems of fixed airflow direction in existing small electrostatic eliminators, which require constant adjustment of the volumetric flask angle or direction by the experimenter during the airflow process, thus increasing the labor intensity of the experimenter and compromising work efficiency and the effectiveness of electrostatic removal.

[0028] refer to Figures 1-3As shown, this application discloses an antistatic device, including a housing 10, a forward and reverse belt conveyor 20, a blocking mechanism 30, and an antistatic mechanism 40. The front side of the housing 10 is provided with an open portion 11 corresponding to the forward and reverse belt conveyor 20. The front side of the open portion 11 is provided with a support platform 12 below. Several protrusions 21 are formed above the belt of the forward and reverse belt conveyor 20, and the gap formed between two protrusions 21 is set as the placement area for volumetric flasks. In actual operation, the operator places the volumetric flasks one by one between the gaps formed by the protrusions 21 at the open portion 11. In this way, it can be ensured that the volumetric flasks will not tip over in the front and back directions when static electricity is removed.

[0029] The blocking mechanism 30 includes a bidirectional drive assembly 31 located inside the rear side of the housing 10 and two baffles 32 connected to the two drive parts of the bidirectional drive assembly 31 to form a block for the volumetric flasks. Before electrostatic removal is performed on the volumetric flasks, the bidirectional drive assembly 31 drives the two baffles 32 to move towards each other until the two baffles 32 are close to the volumetric flasks. In this way, it can be ensured that the volumetric flasks will not tilt to the left or right when electrostatic removal is performed.

[0030] The static eliminator 40 includes an ion fan 41 mounted on the top of the housing 10, a translation drive assembly 42 mounted on the inner wall of the top of the housing 10 along the left-right direction, a lifting drive assembly 43 connected to the translation drive assembly 42, a tilting drive assembly 44 connected to the lifting drive assembly 43, and an air blowing section 46 mounted on the tilting drive assembly 44 and connected to the ion fan 41 via a telescopic corrugated pipe 45. When a set number of volumetric bottles are conveyed into the housing 10 by the forward and reverse belt conveyor 20, the translation drive assembly 42, the lifting drive assembly 43, and the tilting drive assembly 44 cooperate to drive the air blowing section 46 to perform translation, lifting, and tilting movements. During this process, the air generated by the ion fan 41 will be blown through the air blowing section 46 to several volumetric bottles, thereby removing static electricity from several volumetric bottles.

[0031] In some preferred embodiments, the bidirectional drive component 31 of this application is either a bidirectional servo screw module or a bidirectional cylinder. In actual use, those skilled in the art may also choose other types of bidirectional drive components 31 to replace the bidirectional servo screw module or the bidirectional cylinder, which will not be elaborated on here.

[0032] To prevent solvent bottles from falling off the forward and reverse belt conveyor 20 during transport, this application provides anti-detachment brackets 22 on both sides of the forward and reverse belt conveyor 20 in the transport direction. Each anti-detachment bracket 22 has an anti-detachment block 221 on the side facing the forward and reverse conveyor. When the volumetric bottles continue to run at the beginning or end of the forward and reverse belt conveyor 20, the corresponding anti-detachment block 221 will block the corresponding volumetric bottles. Furthermore, both the baffle 32 and the anti-detachment block 221 of this application are made of hard rubber, which can prevent damage to the volumetric bottles and has strong practicality.

[0033] To control the forward and reverse belt conveyor 20, this application provides photoelectric transmitters 50 and photoelectric receivers 60 on the left and right sides of the front end of the forward and reverse belt conveyor 20, respectively. The operating principle is as follows:

[0034] Feeding mode: When the operator places a volumetric bottle between the two protrusions 21 at the loading / unloading position, the light emitted by the photoelectric transmitter 50 will not be received by the photoelectric receiver 60. At this time, the forward and reverse belt conveyor 20 moves backward a set distance in the forward direction. This continues until a set number of volumetric bottles are placed above the belt conveyor.

[0035] Feeding mode: When the operator picks up a volumetric bottle at the feeding position, the light emitted by the photoelectric transmitter 50 will be received by the photoelectric receiver 60. At this time, the forward and reverse belt conveyor 20 will move forward in reverse by a set distance. This process continues until a set number of volumetric bottles above the forward and reverse belt conveyor 20 are removed.

[0036] Of course, the loading and unloading positions mentioned above refer to the same location, and the loading and unloading modes mentioned above are controlled by an external controller, which will not be elaborated on here.

[0037] In some preferred embodiments, the translation drive assembly 42 and the lifting drive assembly 43 of this application are both electric slides. In actual use, those skilled in the art may also choose other types of translation drive assemblies 42 and lifting drive assemblies 43 to replace the electric slides, which will not be elaborated on here.

[0038] As one embodiment of this utility model, the flipping drive assembly 44 of this application includes a transport block 431 disposed on the lifting part of the lifting drive assembly 43, a servo electric cylinder 441 disposed at the bottom of the transport block 431, a linear rack 4411 disposed on the piston rod of the servo electric cylinder 441, two side plates 442 disposed on both sides below the servo electric cylinder 441, a flipping drive shaft 443 rotatably disposed between the two side plates 442, a gear 444 fixed on the flipping drive shaft 443 and meshing with the linear rack 4411, and a flipping plate 445 connected to the gear 444. When the air blowing part 46 is controlled to adjust the flipping angle, during the extension and retraction of the piston rod driven by the servo electric cylinder 441, the linear rack 4411 will drive the gear 444 to rotate, causing the flipping plate 445 to be flipped and adjusted. Since the air blowing part 46 is disposed on the flipping plate 445, the air blowing part 46 will realize the flipping adjustment.

[0039] Based on the above embodiments, the blowing section 46 of this application includes a blowing block 461 and several pressurized blowing nozzles 462 disposed on a flip plate 445. The blowing block 461 has an air chamber (not shown) connected to the telescopic corrugated pipe 45. Several pressurized blowing nozzles 462 are connected and installed on the blowing block 461 and communicate with the air chamber. When electrostatic removal is performed on several volumetric flasks, the air sent by the ion blower 41 enters the air chamber and is then blown to the several volumetric flasks through the several pressurized blowing nozzles 462.
