Description

Technical Field

[0001] This application belongs to the field of cleanroom sampling robot technology, specifically relating to a workstation robot body anti-contamination structure. Background Technology

[0002] The dust particle counting and airborne bacteria sampling robot (also known as the workstation robot) is based on SLAM algorithm and LiDAR obstacle avoidance system to ensure accurate site arrival, facilitating the sampling of particles and airborne bacteria in the cleanroom environment. The workstation robot includes a station body with a sampling port on it. Inside the station body, there is an air extraction component that communicates with the sampling port. A petri dish is then placed on the station body at the sampling port position. The air extraction component is connected to the outside of the station body through a pipe. By activating the air extraction component, airflow enters the sampling port after passing through the air extraction component, and then the airflow passes through the petri dish, allowing the dust particles and airborne bacteria in the air to remain on the petri dish, completing the sampling.

[0003] In the prior art, the air extraction component of the workstation robot is located inside the station body. During the operation of the air extraction component, heat is generated. In order to reduce the accumulation of heat, a cooling fan is installed inside the station body, and a through hole is provided at the bottom of the station body. After the cooling fan is turned on, the gas inside the station body can circulate with the airflow outside the station body, thereby reducing the accumulation of heat inside the station body.

[0004] However, setting through holes at the bottom of the station will connect the inside and outside of the station. When the workstation robot is not working, dust particles in the air can easily enter the interior of the station. When the workstation robot samples particles and airborne bacteria in the cleanroom environment, the fan will also work, which can easily blow dust particles from inside the station into the cleanroom. Utility Model Content

[0005] This application provides a workstation robot body anti-contamination structure, which aims to solve the problem that in the prior art, dust particles in the air can easily enter the body of the workstation, and during normal testing, the dust particles inside the workstation can easily be blown into the clean room.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A pollution-proof structure for a workstation robot is provided, comprising:

[0008] Frame;

[0009] The upper sealing plate and the lower sealing plate are respectively connected to the top and bottom of the frame; both the upper sealing plate and the lower sealing plate are sealed to the frame; the lower sealing plate is provided with an air inlet and an air outlet, and filters are connected to the inner side of the air inlet and the air outlet of the lower sealing plate;

[0010] An air collector hood is connected to the air outlet side of the fan; the air collector hood is connected to the filter at the air outlet through a pipe, so that the gas inside the frame is discharged from the air outlet after passing through the air collector hood and the filter, and the gas outside the frame enters the frame after passing through the air inlet and the filter.

[0011] In one possible implementation, the air collector shroud has a conical structure, with the large end of the shroud connected to the air outlet side of the fan, and the small end of the shroud connected to a filter at the air outlet via a pipe.

[0012] In one possible implementation, the lower sealing plate is provided with an air passage pipe at the air inlet and air outlet positions. The bottom of the air passage pipe is connected to the lower sealing plate through a flange, and a sealing structure is provided between the flange and the lower sealing plate. The filter is inserted into the air passage pipe through a rubber hose, and after the rubber hose is inserted into the air passage pipe, the rubber hose and the air passage pipe are sealed together.

[0013] In one possible implementation, the top outer periphery of the upper sealing plate has an outwardly protruding first outer edge, and after the frame is inserted and fitted with the upper sealing plate, the top of the frame contacts the bottom of the first outer edge;

[0014] The bottom outer periphery of the lower sealing plate has a second outwardly protruding outer edge. After the frame is inserted and fitted with the lower sealing plate, the bottom of the frame contacts the top of the second outer edge. The outer peripheral walls of the upper sealing plate and the lower sealing plate are both connected with sealing gaskets.

[0015] In one possible implementation, the outer peripheral wall of the upper sealing plate is provided with a plurality of threaded holes at intervals, and the sealing gasket of the upper sealing plate has through holes aligned with the threaded holes; the frame has connecting holes aligned with the threaded holes of the upper sealing plate, and the frame is fixed to the upper sealing plate by bolts.

[0016] The bottom sealing plate has several through holes spaced apart near the edge at its top. A connecting plate is connected to the inner side of the frame. The connecting plate contacts the top of the bottom sealing plate and has threaded holes aligned with the through holes on the bottom sealing plate. The connecting plate is fixed to the bottom sealing plate with bolts.

[0017] In one possible implementation, there are several connecting plates, each corresponding to a threaded hole; or the connecting plate is an integral frame-shaped structure.

[0018] In one possible implementation, the fan is bolted to the lower cover plate, and the air collector is welded to the air outlet side of the fan, or the air collector is bolted to the air outlet side of the fan.

[0019] In one possible implementation, the opposite sides of the frame are recessed inward near the top to form grooves, and the bottom of the upper sealing plate contacts the top of the recessed portion.

[0020] In one possible implementation, the top of the upper sealing plate is a work surface, and a plurality of support components are connected to the lower sealing plate. The top of the support components contacts the bottom of the upper sealing plate to support the upper sealing plate.

[0021] In one possible implementation, the filter at the air inlet is connected to the inside of the frame, and when gas from outside the frame enters the frame through the air inlet and the filter, the filter can filter the air entering the frame.

[0022] This application provides a pollution prevention structure for a workstation robot. Compared with existing technologies, when the workstation robot is not working, dust in the external air cannot enter the frame. If the external air enters the frame, it must first pass through a filter, which filters airborne dust particles, thereby reducing the number of dust particles entering the robot. When the workstation robot is working normally, dust particles on its surface are removed through an air shower, and then the workstation robot samples the cleanroom. During sampling, a fan operates simultaneously, blowing the air inside the frame towards the air collection hood and filter, and then exhausting it from the air outlet. Through the above setup, the filter filters the air exiting the frame, reducing the number of dust particles blown into the cleanroom. The air outside the frame enters the frame after passing through the air inlet and filter, and the filter filters the air entering the frame, thereby reducing the number of dust particles entering the frame.

[0029] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0030] Please refer to the following: Figures 1 to 5 The present application provides a description of a pollution prevention structure for a workstation robot. The aforementioned anti-pollution structure for a workstation robot includes a frame 1, an upper sealing plate 2, a lower sealing plate 3, and an air collection hood 4. The upper sealing plate 2 and the lower sealing plate 3 are respectively connected to the top and bottom of the frame 1. Both the upper sealing plate 2 and the lower sealing plate 3 are sealed to the frame 1. The lower sealing plate 3 is provided with an air inlet 31 and an air outlet 32, and filters 5 are connected to the inner sides of both the air inlet 31 and the air outlet 32. The air collection hood 4 is connected to the air outlet side of the fan 6. The air collection hood 4 is connected to the filter 5 at the air outlet 32 ​​through a pipe, so that the gas inside the frame 1 is discharged from the air outlet 32 ​​after passing through the air collection hood 4 and the filter 5, and the gas outside the frame 1 enters the frame 1 after passing through the air inlet 31 and the filter 5. The filter 5 at the air inlet 31 is connected to the inside of the frame 1, and when the gas outside the frame 1 enters the frame 1 through the air inlet 31 and the filter 5, the filter 5 can filter the air entering the frame 1.

[0031] This application provides a workstation robot body anti-pollution structure. Compared with the prior art, when the workstation robot is not working, dust in the external air of the frame 1 cannot enter the frame 1. If the external air enters the frame 1, it must first pass through the filter 5. The filter 5 can filter the dust particles in the air, thereby reducing the dust particles entering the body. When the workstation robot is working normally, the dust particles on the surface of the workstation robot are removed by the air shower, and then the workstation robot samples the cleanroom. During the sampling process, the fan 6 works simultaneously. The fan 6 can blow the air in the frame 1 towards the air collection hood 4 and the filter 5, and discharge the air from the frame 1 through the air outlet 32. Through the above settings, the filter 5 filters the air discharged from the frame 1, which can reduce the dust particles blown into the cleanroom. The air outside the frame 1 enters the frame 1 after passing through the air inlet 31 and the filter 5. The filter 5 can filter the air entering the frame 1, thereby reducing the dust particles entering the frame 1.

[0032] For example, the fan 6 is bolted to the lower cover plate 3, and the air collector shroud 4 can be welded to the air outlet side of the fan 6, or it can be fixed to the air outlet side of the fan 6 with bolts. After the fan 6 is fixed to the lower cover plate 3, the stability of the fan 6 can be improved, and the risk of displacement during normal operation of the fan 6 can be reduced. A mounting plate 61 is fixedly provided at the bottom of the fan 6, and the mounting plate 61 has through holes. The lower cover plate 3 has threaded holes corresponding to the through holes on the mounting plate 61. When the through holes on the mounting plate 61 are aligned with the threaded holes on the lower cover plate 3, the mounting plate 61 is fixed to the lower cover plate 3 with bolts.

[0033] After the fan 6 is started, the gas inside the frame 1 enters the air intake side of the fan 6 and is discharged from the air outlet side of the fan 6. The discharged gas passes through the air collector shroud 4 and the filter 5 and is discharged from the air outlet 32. Through the above settings, the heat inside the frame 1 can be discharged from the frame 1, reducing the heat accumulated inside the frame 1. After the gas inside the frame 1 is discharged from the air outlet 32, in order to balance the pressure inside and outside the frame 1, the gas outside the frame 1 will enter the frame 1 from the air inlet 31. The gas entering from the air inlet 31 will first be filtered by the filter 5, thus reducing the amount of dust particles entering the frame 1. The flow of gas inside and outside the frame 1 can play a role in heat dissipation.

[0034] In some embodiments, such as Figures 1 to 5 As shown, the air collector shroud 4 has a conical structure. The large end of the air collector shroud 4 is connected to the air outlet side of the fan 6, and the small end of the air collector shroud 4 is connected to the filter 5 at the air outlet 32 ​​through a pipe.

[0035] It should be noted that by connecting the large end of the air collector shroud 4 to the air outlet side of the fan 6, the airflow can be guided, allowing the airflow to enter the filter 5 and finally exit the frame 1 from the air outlet 32. With the above configuration, the air collector shroud 4 is set into a conical structure, which facilitates the connection between the fan 6 and the filter 5, so that the gas discharged by the fan 6 enters the filter 5 after passing through the air collector shroud 4.

[0036] In some embodiments, such as Figures 1 to 5 As shown, the lower sealing plate 3 is provided with an air passage pipe 7 at the air inlet 31 and the air outlet 32. The bottom of the air passage pipe 7 is connected to the lower sealing plate 3 through a flange, and a sealing structure is provided between the flange and the lower sealing plate 3. The filter 5 is inserted into the air passage pipe 7 through a rubber hose. After the rubber hose is inserted into the air passage pipe 7, the rubber hose and the air passage pipe 7 are sealed together.

[0037] It should be noted that the sealing structure can be a sealing ring. When installing the air passage pipe 7, the sealing ring is placed between the flange and the lower sealing plate 3. After being fixed with bolts, the sealing ring can be pressed tightly against the flange and the lower sealing plate 3, thereby achieving a sealing effect at the connection between the flange and the lower sealing plate 3. After installation, the air passage pipe 7 at the air inlet 31 is connected to the air inlet 31, and the air passage pipe 7 at the air outlet 32 ​​is connected to the air outlet 32. After fixing the air passage pipe 7 to the lower sealing plate 3, a rubber hose is inserted into the air passage pipe 7 to achieve a tight fit between the rubber hose and the air passage pipe 7, thereby achieving a sealing effect.

[0038] In some embodiments, such as Figures 1 to 5 As shown, the top outer periphery of the upper sealing plate 2 has a first outwardly protruding outer edge 21. After the frame 1 is inserted and fitted with the upper sealing plate 2, the top of the frame 1 contacts the bottom of the first outer edge 21. The bottom outer periphery of the lower sealing plate 3 has a second outwardly protruding outer edge 33. After the frame 1 is inserted and fitted with the lower sealing plate 3, the bottom of the frame 1 contacts the top of the second outer edge 33. The outer periphery of both the upper sealing plate 2 and the lower sealing plate 3 is connected with a sealing gasket.

[0039] It should be noted that the top of the first outer edge 21 is coplanar with the top of the upper sealing plate 2. After the frame 1 and the upper sealing plate 2 are inserted and fitted together, the inner peripheral wall of the frame 1 contacts the sealing gasket of the outer peripheral wall of the upper sealing plate 2, and the top of the frame 1 contacts the bottom of the first outer edge 21. With the above arrangement, after the frame 1 and the upper sealing plate 2 are fixed together, the sealing between the upper sealing plate 2 and the frame 1 can be guaranteed, and the situation of the upper sealing plate 2 falling into the frame 1 can be avoided.

[0040] The bottom of the second outer edge 33 is coplanar with the bottom of the lower sealing plate 3. After the frame 1 and the lower sealing plate 3 are inserted and fitted, the inner peripheral wall of the frame 1 contacts the sealing gasket of the outer peripheral wall of the lower sealing plate 3, which can improve the sealing performance between the frame 1 and the lower sealing plate 3.

[0041] In some embodiments, such as Figures 1 to 5 As shown, the outer peripheral wall of the upper sealing plate 2 is provided with several threaded holes at intervals, and the sealing gasket of the upper sealing plate 2 has through holes aligned with the threaded holes; the frame 1 has connecting holes aligned with the threaded holes of the upper sealing plate 2, and the frame 1 is fixed to the upper sealing plate 2 by bolts; the top of the lower sealing plate 3 is provided with several through holes at intervals near the edge, and the inner side of the frame 1 is connected to a connecting plate 11, which contacts the top of the lower sealing plate 3, and the connecting plate 11 has threaded holes aligned with the through holes on the lower sealing plate 3; the connecting plate 11 is fixed to the lower sealing plate 3 by bolts, the threaded end of the bolt passes through the bottom of the lower sealing plate 3 and is threadedly engaged with the connecting plate 11 at the top of the lower sealing plate 3, and a sealing gasket is provided between the bolt nut and the bottom of the lower sealing plate 3 to ensure the sealing between the nut and the lower sealing plate 3.

[0042] It should be noted that after the frame 1 and the upper sealing plate 2 are inserted and fitted, the connecting hole on the frame 1 is aligned with the threaded hole on the upper sealing plate 2. At this time, by passing the bolt through the frame 1 and the sealing gasket and threading it with the upper sealing plate 2, the frame 1 can be fixed on the upper sealing plate 2. After tightening the bolt, the frame 1 and the upper sealing plate 2 cooperate to press against the sealing gasket, which can improve the sealing performance between the frame 1 and the upper sealing plate 2.

[0043] By fixing a connecting plate 11 inside the frame 1, after the frame 1 and the lower sealing plate 3 are inserted and matched, the through holes on the connecting plate 11 correspond one-to-one with the threaded holes on the lower sealing plate 3. The threaded end of the bolt passes through the connecting plate 11 and is threadedly matched with the lower sealing plate 3, so that the connecting plate 11 can be fixed on the lower sealing plate 3, thereby fixing the frame 1 on the lower sealing plate 3.

[0044] In some embodiments, such as Figures 1 to 5 As shown, there are several connecting plates 11, each corresponding to a threaded hole; or the connecting plate 11 is an integral frame structure. In this embodiment, the integral frame structure of the connecting plate 11 is used as an example. The connecting plate 11 is fixed on the inner peripheral wall of the frame 1. After the frame 1 and the lower sealing plate 3 are inserted and fitted, the through holes on the connecting plate 11 correspond one-to-one with the threaded holes on the lower sealing plate 3. The connecting plate 11 can be fixed on the lower sealing plate 3 by bolts. By setting the connecting plate 11 as an integral structure, the connection strength between the connecting plate 11 and the frame 1 can be improved.

[0045] In some embodiments, such as Figures 1 to 5As shown, the two opposite sides of the frame 1 are recessed inward to form grooves 12 near the top, so as to facilitate the handling of the frame 1; the bottom of the upper sealing plate contacts the top of the recessed part; for the outside of the frame 1, the frame 1 is recessed inward to form grooves 12; for the inside of the frame 1, the above structure is a protruding part, and the upper sealing plate 2 can contact the top of the recessed part.

[0046] It should be noted that by setting a groove 12 near the top of the frame 1, when the frame 1 needs to be manually moved, the operator can place his hand in the groove 12, contact the top of the groove 12, and apply an upward force to the top of the groove 12, which makes it easier for the operator to move the frame 1.

[0047] In some embodiments, such as Figures 1 to 5 As shown, the top of the upper sealing plate 2 is a workbench, and several support components are connected to the lower sealing plate 3. The top of the support components contacts the bottom of the upper sealing plate 2 to support the upper sealing plate 2.

[0048] It should be noted that the top of the upper sealing plate 2 is a workbench surface, and sampling components need to be installed on the top of the upper sealing plate 2. Therefore, supporting the upper sealing plate 2 with supporting components can improve the supporting strength and stability of the upper sealing plate 2.

[0049] For example, the top of the support component can be fixed to the upper sealing plate 2 with bolts, which can strengthen the connection between the support component and the upper sealing plate 2. Since the two ends of the support component are connected to the upper sealing plate 2 and the lower sealing plate 3 respectively, in order to facilitate the installation of the frame 1 between the upper sealing plate 2 and the lower sealing plate 3, the frame is divided into four parts, each of which is installed on the same side of the upper sealing plate 2 and the lower sealing plate 3. After the four parts are installed, the frame 1, the upper sealing plate 2 and the lower sealing plate 3 can form a closed shell. A sealing strip is provided at the connection position of two adjacent parts to ensure the sealing performance of the connection position of two adjacent parts.

[0050] In some embodiments, such as Figures 1 to 5 As shown, the lower sealing plate 3 is provided with an exhaust port 34, and the frame 1 is provided with an air extraction component 8. The air extraction component 8 is fixed on the lower sealing plate 3. The inlet and outlet of the air extraction component 8 are connected to the sampling tube and the exhaust port 34 through pipes, respectively. A filter 5 is provided at the exhaust port 34.

[0051] In addition, the entire outer shell is made of 316L stainless steel and thick-film aluminum oxide, with a smooth and clean surface, making it easy to clean. It also has good sealing properties, allowing for the use of a spray bottle to spray the robot with cleaning agents and disinfectants such as alcohol, hydrogen peroxide, and sporicidal agents; the materials used are also resistant to cleaning agents and disinfectants commonly used in pharmaceutical companies.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
