Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting equipment, in particular to a dry ice sandblasting device. Background Art

[0002] In the field of cleaning and renovation of mechanical parts, how to achieve surface reconstruction of the parts to be renovated is a key project. To achieve surface reconstruction, the old surface layer must be removed first. Sandblasting is a common and efficient way to remove the surface.

[0003] However, ordinary sandblasting relies on the mechanical shear force of abrasives to destroy and remove surface coatings through impact. This method usually has a large cutting force and produces a lot of dust. High-pressure water is poured into the sandblasting tube to wet the abrasive, which can avoid most of the dust, but will also produce wastewater that is difficult to treat. Therefore, dry ice cleaning is a method that can avoid the generation of a large amount of dust. Dry ice is sprayed at high speed onto the surface to be treated by a dry ice cleaning machine. Combined with a certain proportion of abrasives, better cleaning effects can be achieved.

[0004] During cleaning and renovation, it is often necessary to observe the area being cleaned, so that the area being cleaned can be always known to avoid missing or repeated cleaning. However, the presence of dry ice will naturally interfere with vision, and the "aerosol" formed will make it impossible for people to see the work surface clearly, let alone use robots to operate.

[0028] It will be understood by those skilled in the art that, unless otherwise stated, the singular forms "a", "an", "said" and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present application refers to the presence of the features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0029] The technical solution of the present invention and how the technical solution solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0030] The dry ice sandblasting device provided by the utility model application is as follows: Figure 1 and Figure 2 As shown, it includes: an industrial robot 100, a dry ice sandblasting assembly 200, a workbench 300, a work room 400 with a door, and several cameras 500. The industrial robot 100 can be directly selected from common suitable products in the prior art, and can be mobile or fixed. The camera 500 can also be directly purchased from a monitoring camera 500 in the prior art, and its signal is connected to a corresponding console so that the operator can observe the working conditions in the work room 400.

[0031] The industrial robot 100 and the workbench 300 are both arranged on the floor of the workroom 400, and the camera 500 is arranged on the wall or ceiling (not shown) of the workroom 400. The industrial robot 100 is arranged beside the workbench 300, so that when the workpiece is placed on the workbench 300, the working range of the industrial robot 100 covers the workpiece. The camera 500 is arranged on the cavity wall or ceiling of the workroom 400, which ensures the monitoring line of sight without causing adverse effects on the camera 500.

[0032] like Figure 2 As shown, the dry ice sandblasting assembly 200 includes a dry ice cleaning machine 210 (only part of the figure is shown, i.e., the output pipe of the dry ice cleaning machine, the same below), a nozzle 220, an abrasive supply unit 230 (only part of the figure is shown, i.e., the output pipe of the abrasive supply unit, the same below) and at least one suction pipe 240 (the suction device is not shown). The dry ice cleaning machine 210 and the abrasive supply unit 230 are respectively connected to the nozzle 220, and the nozzle of the suction pipe 240 is arranged near the nozzle of the nozzle 220. The nozzle 220 can be detachably mounted on the mechanical arm of the industrial robot 100. The dry ice cleaning machine 210 can use compressed air to quickly spray dry ice particles toward the surface to be worked. After hitting the surface to be worked, the dry ice vaporizes and sublimates, generating a relatively strong expansion effect, and at the same time embrittles the working surface, so that the embrittled surface layer is peeled off from the workpiece by relying on the impact force. The dry ice cleaning machine 210 adopts the finished product in the prior art, and the abrasive supply unit 230 is used to assist in supplying sandblasting abrasive to the dry ice cleaning machine 210. The suction pipe 240 of the present application is naturally connected to a suction device, such as a vacuum pump or a vacuum cleaner, etc., and a common suitable existing product can also be directly selected. After the dry ice produces a large amount of "aerosol" on the surface of the workpiece, it will seriously hinder the camera 500 from observing the working surface. Through the suction pipe 240, these "aerosols" can be sucked away in time to avoid this obstruction, ensuring that the camera 500 can clearly monitor the working process.

[0033] Optionally, in another embodiment of the present application, the suction pipe 240 is partially attached to the nozzle 220, and the nozzle of the suction pipe 240 is attached to the pipe body of the nozzle 220. The suction pipe 240 and the nozzle 220 are bundled together and driven by the industrial robot 100. Wherever the dry ice produces "aerosol", the suction pipe 240 can clean up the "aerosol". The nozzle 220 is detachably connected to the mechanical arm of the industrial robot 100, so a special connection structure matching the industrial robot 100 is provided on the nozzle 220. These connection structures can be threaded nuts, clamps, snap-fit ​​connections, etc. The specific suitable structure can be found in the prior art, and this application will not elaborate on it.

[0034] Optionally, in combination with the foregoing embodiments and implementations, in a specific implementation of the present application, Figure 3 As shown, three suction pipes 240 are provided, and the three suction pipes 240 are evenly distributed along the circumference of the nozzle 220, and the main pipe opening 251 of the suction pipe 240 is arranged behind the pipe opening of the nozzle 220. The three suction pipes 240 are connected to the same suction device, specifically, a transition box 250 is set on the nozzle 220, and the three suction pipes 240 all extend from the transition box 250, and the transition box 250 is provided with a suction port, which is connected to the suction device through a pipeline. The three suction pipes 240 can improve the operating efficiency at the suction port, and the suction pipes 240 are evenly distributed along the circumference of the nozzle 220, which can ensure that the suction pipes 240 quickly suck the gas around the nozzle 220. The dry ice particles and abrasives ejected at high speed from the nozzle 220 are usually not sucked away by the suction pipe 240. However, to ensure this effect, the nozzle of the suction pipe 240 is arranged behind the nozzle of the nozzle 220, that is, the nozzle of the nozzle 220 is more protruding and can be closer to the surface of the workpiece to be processed, while the nozzle of the suction pipe 240 is not so close to the surface of the workpiece and is located at a relatively backward position, thereby avoiding unnecessary influence on the airflow ejected from the nozzle 220.

[0035] Optionally, in another embodiment of the present application, Figure 2 to Figure 4As shown, the dry ice sandblasting assembly 200 also includes a mixing tube section 260 with a hollow structure, the output pipe of the dry ice cleaning machine 210 is axially connected to the mixing tube section 260, the abrasive supply part 230 is connected to the radial direction of the mixing tube section 260, and the nozzle 220 is connected to the side of the output pipe of the mixing tube section 260 that is away from the dry ice cleaning machine 210. Through the mixing tube section 260 with a hollow structure, the dry ice particles, compressed air and abrasive output by the dry ice cleaning machine 210 are quickly mixed and uniform in the mixing tube section 260. The abrasive enters the output airflow from the radial direction of the output airflow of the dry ice cleaning machine 210, which can ensure a high mixing efficiency. Optionally, in a specific implementation of the present application, a handrail for handholding is provided on the peripheral side of the mixing tube section 260 (not shown in the figure). The handrail can facilitate the operator to move and disassemble the dry ice sandblasting assembly 200.

[0036] Optionally, in another embodiment of the present application, Figure 4 As shown, the abrasive supply unit 230 further includes a delivery pipe 231 and a storage tank 232, and the storage tank 232 is connected to the nozzle 220 through the delivery pipe 231. For operation scenarios that do not require long-term sandblasting, abrasives can be stored in a small storage tank 232, which can simplify the complex abrasive supply system.

[0037] Specifically, in some specific implementations of an embodiment of the present application, such as Figure 1 As shown, three cameras 500 are set on the walls of the workroom 400 around the workbench 300, and one camera 500 is set on the ceiling (not shown in the figure) of the workroom 400 above the workbench 300, and the camera 500 faces the workbench 300.

[0038] The dry ice sandblasting device provided by the utility model combines a dry ice cleaning machine 210 and a shot blasting surface treatment device. The nozzle 220 can be hand-held by the manipulator of the industrial robot 100. Cameras 500 are arranged on the wall and ceiling of the workroom 400 body. The working surface of the workpiece is observed by the camera 500, which can adapt to the working surface of the workpiece with complex shapes. In addition, the suction pipe 240 arranged beside the nozzle 220 can be used to timely suck the atomized carbon dioxide, thereby ensuring that the camera 500 has a good visual effect and also ensuring the working efficiency of the dry ice sandblasting operation.
