Detailed Description

The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in combination with embodiments.

The application provides a wall climbing paint spraying robot, wherein, wall climbing paint spraying robot include wall climbing robot main part 10 and install in wall climbing robot main part 10 in order to follow wall climbing robot main part removes exhaust treatment device that sprays paint.

When the wall climbing robot body 10 moves to perform paint spraying operation, the wall climbing robot body 10 can be moved along with the wall climbing robot body 10 through a paint spraying waste gas treatment device, so that paint spraying waste gas is effectively treated at the operation position of the paint spraying operation, and the pollution of the paint spraying waste gas to the environment is reduced.

Wherein, spray paint exhaust treatment device has waste gas collection function and waste gas treatment function. In particular, the exhaust gas collection and treatment can be performed simultaneously in the paint spraying operation, preferably, the exhaust gas generated in the paint spraying operation can be collected at the paint spraying operation and then conveyed to a separate position for treatment, so that interference to the paint spraying operation is avoided. Moreover, the collection and treatment of the exhaust gas are carried out separately, so that the exhaust gas treatment is relatively far away from the painting operation position, the influence on the painting operation is not required to be considered, and the arrangement required by the exhaust gas treatment is facilitated.

In a preferred embodiment of the present application, as shown in fig. 1 and 3, the paint spray exhaust gas treatment apparatus includes an exhaust gas collection tank 30 and an exhaust gas treatment tank 40 mounted to the wall climbing robot body 10, the wall climbing paint spray robot includes a spray gun 20, the spray gun 20 is mounted in the exhaust gas collection tank 30 and is capable of spraying paint through a paint spray window 31 of the exhaust gas collection tank 30, the exhaust gas treatment tank 40 includes a tank 41 and an exhaust gas treatment unit 42 provided in the tank 41, the tank 41 is provided with an inlet 411 and an outlet 412 to allow exhaust gas to be treated to enter from the inlet 411, pass through the exhaust gas treatment unit 42, and be discharged from the outlet 412, and the inlet 411 is communicated with an inner space of the exhaust gas collection tank 30. Wherein the spray gun 20 is installed in the exhaust gas collecting tank 30, the exhaust gas generated during the painting operation is substantially concentrated in the exhaust gas collecting tank 30 so as to enter the tank 41 through the inlet 411, and then the exhaust gas is treated by the exhaust gas treatment unit 42, and the treated standard gas can be discharged from the outlet 412.

In order to facilitate the flow of exhaust gases from the exhaust gas collection tank 30 into the tank 41 and along a path from the inlet 411 through the exhaust gas treatment unit 42 to the outlet 412, the spray paint exhaust treatment device may comprise a fan 70 for directing the flow of exhaust gases. The fan 70 may be disposed at an appropriate position of the exhaust flow path to guide the exhaust. For example, in the embodiment shown in fig. 1, a blower 70 may be provided at the outlet 412 of the housing 41, and the flow of exhaust gas may be guided by the negative pressure generated by the blower 70.

Preferably, as shown in fig. 3, a paint mist filtering unit 50 is disposed in the exhaust gas collecting tank 30, upstream of a position where the exhaust gas collecting tank 30 communicates with the inlet 411 in a flow direction of paint spray exhaust gas. By providing the paint mist filter unit 50, impurities (e.g., particles falling off from the surface of the work during the painting operation) in the exhaust gas can be filtered before the exhaust gas treatment by the exhaust gas treatment unit 42, thereby reducing the load of the exhaust gas treatment unit 42.

The paint mist filter unit 50 may take various suitable forms to achieve the filtering of exhaust gas, among others. For example, the paint mist filter unit 50 may include filter cotton. Preferably, the paint mist filter unit 50 may be detachably provided in the exhaust gas collection tank 30 so as to be replaced in time when the filtering function is lowered. For example, the paint mist filter unit 50 may be mounted to the exhaust gas collection box 30 by a quick-change structure. Specifically, the paint mist filtering unit 50 can be provided with a plate-type quick-release structure, the waste gas collecting box 30 can be provided with a mounting structure matched with the plate-type quick-release structure, and the filter cotton can be fixed on the plate-type quick-release structure.

In addition, as shown in fig. 3, an air-permeable partition 60 may be disposed in the exhaust gas collection tank 30, the spray gun 20 and the paint mist filtering unit 50 may be disposed at both sides of the air-permeable partition 60, respectively, and the exhaust gas collection tank 30 may be in communication with the inlet 411 and the paint mist filtering unit 50 may be disposed at the same side of the air-permeable partition 60. Thus, when the exhaust gas is guided by the blower 70 from the side of the spray gun 20 through the air-permeable partition 60 to the side of the paint mist filter unit 50, the exhaust gas will enter the box 41 through the connection or remain on the side of the paint mist filter unit 50, and the negative pressure of the blower 70 and the air-permeable partition 60 can prevent the exhaust gas from returning to the side of the spray gun 20 and overflowing due to the negative pressure, so that the exhaust gas is ensured to pass through the paint mist filter unit 50 and enter the box 41 for treatment.

Wherein the air-permeable partition 60 may take various suitable forms as long as it is capable of allowing the exhaust gas to pass through under the guide of the blower 70 and providing a barrier to the reverse pass of the exhaust gas. For example, the air-permeable separator 60 may be a steel wire mesh.

To ensure that the exhaust gas flows through the exhaust treatment unit 42 under the direction of the blower 70 after entering the housing 41, a flow path of the exhaust gas may be defined within the housing 41. Specifically, as shown in fig. 3, a sealing plate 413 is disposed in the case 41, and the sealing plate 413 and the exhaust gas treatment unit 42 define an airflow path in the case 41. Wherein the sealing plate 413 is in sealing contact with the wall of the case 41 to define a unidirectional air flow path from the inlet 411 to the outlet 412 in the case 41 in cooperation with the exhaust gas treatment unit 42, so that the exhaust gas can flow along the air flow path only after entering from the inlet 411 under the guidance of the blower 70 and can be discharged from the outlet 412 after passing through the exhaust gas treatment unit 42.

Wherein the flow path may be extended as much as possible in order to increase the travel of the exhaust gas through the exhaust treatment unit 42 to optimize the exhaust treatment effect. Preferably, the air flow path is a labyrinth path, that is, the air flow path is made to meander inside the case 41 and has a portion extending back, thereby giving consideration to both the extension of the air flow path and the space utilization of the case 41. In this case, the exhaust gas treatment units 42 may be provided in different regions of the airflow path (for example, the airflow path may be divided into a plurality of regions), respectively; alternatively, an integrated exhaust treatment unit 42 may be provided within the housing 41 and the airflow path serpentine through different locations of the exhaust treatment unit 42.

The specific arrangement of the air flow path and the position of the sealing plate 413 may be determined according to the shape of the case 41, the position of the blower 70, and the like. Preferably, as shown in fig. 3, the fan 70 is disposed at the middle of the case 41, and two air flow paths symmetrically located at both sides of the fan 70 are formed in the case 41.

Specifically, as shown in fig. 3, the case 41 shown in fig. 3 is a top cross-sectional view, wherein the case 41 is formed in a rectangular parallelepiped, and in fig. 3, the up-down direction is the width direction of the case 41, and the left-right direction is the length direction of the case 41. The outlet 412 is provided at the middle of the top surface of the case 41, the blower 70 is installed at the outlet 412, and the inlet 411 is provided at one side of the case 41 in the length direction, wherein the inlet 411 may be opened from one side of the case 41, or a plurality of inlets 411 may be provided at one side of the case 41 to allow exhaust gas to uniformly enter. A sealing plate 413 extending in the width and height directions of the case 41 is provided between the outlet 412 and the inlet 411, the sealing plate 413 being in sealing contact with the top of the case 41, the sealing plate 413 extending in the width direction and having a gap g1 with the side of the case 41 in the width direction. Exhaust gas treatment units 42 are provided on both sides of the plate surface of the sealing plate 413, respectively, and a gap g2 is provided between the exhaust gas treatment unit 42 provided between the other side of the sealing plate 413 in the longitudinal direction of the housing 41 and the other side. To form two air flow paths, the exhaust gas treatment units 42 are symmetrically disposed on both sides of the width direction of the case 41.

The internal space of the case 41 is divided into a region a between the first sealing plate 413 and the inlet 411, a region B between the sealing plate 413, the widthwise side of the case 41, and the outer peripheral region defined between the exhaust gas treatment units 42 therebetween, and a region C between the widthwise side of the case 41 and the exhaust gas treatment units 42 therebetween of the sealing plate 413. In the region a and the region B, there is provided an exhaust gas treatment unit 42, as indicated by an arrow in fig. 3, the flow path of the exhaust gas is: inlet 411→region a→gap g1→region b→gap g2→region c→outlet 412.

It is preferable that a plurality of exhaust gas treatment units 42 be provided in each of the regions a and B as shown in fig. 3 to ensure that the exhaust gas is sufficiently treated by the exhaust gas treatment units 42. Specifically, a plurality of exhaust gas treatment units 42 are disposed in the area a and the area B side by side along the width direction of the casing 41, and the exhaust gas needs to flow through all the exhaust gas treatment units 42 in the area a to enter the gap g1 between the sealing plate 413 and the side of the casing 41 in the width direction, and after the exhaust gas passes through one exhaust gas treatment unit 42 in the area B, the exhaust gas cannot directly enter the area C and is discharged from the outlet, but must pass through one exhaust gas treatment unit 42 and enter the area C from the gap g2, so that the exhaust gas flows through the exhaust gas treatment unit 42 as fully as possible.

In order to allow the exhaust treatment tank 40 to have a stable center of gravity and to allow the exhaust treatment tank 40 to be easily mounted to the wall climbing robot body 10, the tank body 41 may have a regular three-dimensional shape. Preferably, as shown in fig. 1, the box 41 is a cuboid, the bottom of the box 41 is connected with the wall climbing robot body 10, the fan 70 protrudes from the top of the box 41, and the exhaust gas collecting box 30 is disposed at one end of the wall climbing robot body 10 along the length direction of the box 41. Specifically, the case 41 may extend from one end to the other end of the wall climbing robot body 10 so as to be disposed in close proximity to the exhaust gas collection tank 30, so that the case 41 communicates with the exhaust gas collection tank 30.

In addition, it is preferable that the distance between the spray gun 20 and the paint window 31 is adjustable. Thereby, the distance between the spray gun 20 and the surface to be sprayed of the workpiece can be controlled, thereby controlling the amount of exhaust gas recovery and the quality of exhaust gas recovery affected thereby (the closer the distance between the spray gun 20 and the surface to be sprayed is, the larger the amount of exhaust gas overflows the exhaust gas collection tank 30, the worse the quality of recovery). In particular, the adjustment of the distance between the spray gun 20 and the spray window 31 can be achieved in a suitable manner. For example, spray gun 20 may be mounted to exhaust gas collection box 30 by a gun rack, which may be provided with a plurality of mounting positions to adjust the distance between spray gun 20 and spray window 31. Specifically, the gun rack may be provided with a plurality of mounting holes aligned in a direction perpendicular to the paint window 31, and the spray gun 20 may be selectively mounted in one of the mounting holes; alternatively, the gun rest may be of a telescopic structure to be telescopic toward or away from the paint window 31, thereby adjusting the distance between the gun 20 and the paint window 31.

In this application, the exhaust treatment unit 42 may take various suitable forms to treat the exhaust to a degree that enables emissions. Since the exhaust gas generated from the painting work is VOC exhaust gas, the exhaust gas treatment unit 42 may be configured to be capable of adsorbing the VOC exhaust gas. Preferably, the exhaust gas treatment unit 42 may include activated carbon fiber cotton.

In addition, it is preferable that the exhaust gas treatment unit 42 is detachably installed in the case 41 so as to be replaced when the treatment capacity of the exhaust gas treatment unit 42 is lowered. Specifically, the exhaust gas treatment unit 42 may include a plate-type frame that can be quickly replaced in cooperation with the assembly structure of the case 41, and an exhaust gas treatment member (e.g., activated carbon fiber cotton) mounted to the plate-type frame, and when the treatment capacity of the exhaust gas treatment member is lowered, the plate-type frame is simply removed from the assembly structure and replaced with a new exhaust gas treatment unit 42.

In the present application, the wall climbing robot body 10 may take various suitable forms as long as it can move along the surface of the work and be positioned at the work position. For example, in the embodiment shown in fig. 1 and 2, the wall climbing robot body 10 includes a frame 11, a traveling mechanism 12 mounted to the frame 11, and a magnetic member 13, wherein the traveling mechanism 12 is provided so as to be capable of being driven and capable of moving in any direction on the surface of the workpiece. The magnetic element 13 can make the wall climbing robot body 10 move close to the surface of the workpiece by means of magnetic attraction. The wall climbing robot body 10 may also be provided with a delivery tube positioning frame 14 to position a delivery tube P for delivering paint to the spray gun 20, which may extend to a paint supply unit remote from the wall climbing robot body 10.

In addition, the wall-climbing paint robot of the present application may further include a vision system 80 and a control unit 90, the vision system 80 may be provided at an appropriate position to monitor the operation of the wall-climbing paint robot and transmit a monitoring signal to the control unit 90, and the control unit 90 may control the corresponding operation of the wall-climbing paint robot (including the movement of the wall-climbing robot body 10, the paint flow rate of the spray gun 20, etc.) according to feedback of the vision system 80.
