At present, when metal and nonmetal workpieces are processed, burrs, barbs, foreign matters and the like may be generated on the workpieces due to the requirements of the processing technology. For example, in the case of plastic products, common molding methods include injection molding, die drawing or cast molding, and when these molding methods are used, fine burrs are often generated on the mold parting line or other edges, and these burrs may be larger or smaller due to different processes and different shapes of parts. In some cases, jaggies, drawn objects and the like are formed at the edge; in the case of metal products, barbs, burrs, and the like may be formed at the edges due to problems in machining tools, machining methods, processes, and the like.
In view of the above problems, it is necessary to perform post-processing on the workpiece after the completion of the main process, such as deburring the workpiece, cleaning foreign matter adhering to the surface of the workpiece, and the like. In the prior art, the post-processing of the workpiece is mainly performed by an operator in three ways, namely, cleaning the workpiece by holding a dry ice gun, cleaning the workpiece by using vibration generated by ultrasonic waves, and cleaning the workpiece, especially a hole, by using a tool such as a scraper or an elongated awl.
However, each of the above three methods has problems, such as low power of the hand-held dry ice gun due to the need to constantly adjust the direction and position during operation to align the gun with the workpiece, the risk of injury to the operator due to contact of the dry ice particles with the skin of the operator, and poor cleaning or inefficiency due to fatigue of the operator; ultrasonic cleaning can only remove surface stains, cannot clean fine burrs and cannot clean impurities in holes, and in addition, cleaning solution used for ultrasonic cleaning needs to be discharged independently; the use of scraper tools cannot properly treat the fine parts, and the labor cost is too high, so that the scraper tools are not suitable for mass production.

Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1 to 4, an embodiment of the present invention provides an apparatus 1 for cleaning a workpiece W using dry ice, the apparatus 1 including:
a crusher 10, wherein the crusher 10 is used for crushing the dry ice raw material into powder;
an air pump 20 for supplying compressed air into the pulverizer 10 to blow the powdery dry ice in the pulverizer 10 with the compressed air;
a spray gun 30 through which the blown dry ice is sprayed;
a drive mechanism 40, said drive mechanism 40 for driving said torch 30 and/or said workpiece W to move relative to each other.
By using the equipment for cleaning the workpiece by using the dry ice, which is provided by the embodiment of the utility model, the problems of low working efficiency and possible personal injury caused by the fact that a worker holds the dry ice gun by hand are solved, in addition, the relative movement of the spray gun and the workpiece is realized due to the arrangement of the driving mechanism, so that the accurate positioning of the spray gun relative to the workpiece is realized, and any part of the workpiece can be cleaned.
In order to enable the lance and the workpiece to be moved relative to each other so that they can be positioned in different positional relationships relative to each other, preferably, as shown in fig. 3, the drive mechanism 40 includes:
a first guide rail 401 for guiding the movement of the spray gun;
a second guide rail 402 disposed perpendicular to the first guide rail 401, the second guide rail 402 for guiding the first guide rail 401 to move;
a third guide rail 403 arranged perpendicular to said first guide rail 401 and perpendicular to said second guide rail 402, said third guide rail 403 being adapted to guide the movement of said workpiece W.
According to another preferred embodiment of the present invention, the relative movement path along which the spray gun 30 and the workpiece W move relative to each other is determined according to the portion of the workpiece W to be cleaned and the desired cleaning interval between the portion to be cleaned and the spray gun 30.
Because the guide rail system in the form of a three-coordinate system is arranged, and the moving distance of the spray gun and the workpiece relative to each other is determined by the required cleaning distance, the spray gun and the workpiece can be positioned relative to each other so that the spray gun is precisely aligned with the part to be cleaned of the workpiece and the distance between the spray gun and the workpiece is proper, the workpiece can be cleaned more precisely, and the 'alignment' cannot be excessively wrong due to long working time of the equipment.
Because various portions of the workpiece may require different degrees of cleaning, the time taken to clean the various portions may also vary. In view of this, it is preferable that respective relative movement speeds at which the torch 30 and the workpiece W move relative to each other at different positions in the relative movement path be determined in accordance with a required cleaning time of the portion to be cleaned.
Referring to fig. 5, it is preferable that the pulverizer 10 is provided with a vibrator 101, and the vibrator 101 is used to vibrate dry ice that has been pulverized into powder to prevent freezing.
