Optionally, the moving device 10 may rotate to sequentially perform surface coating on the printed object through the coating device 20 and surface curing through the curing device 30, so that the post-processing of the printed object may be automated, thereby improving the processing efficiency and the processing effect.
Further, since oxygen has a barrier effect on the curing of the curing material, the surface treatment in an environment with a high oxygen content may have a certain effect on the treatment effect, and therefore, the post-treatment apparatus may further include a housing and a gas generator, the moving device 10, the coating device 20 and the curing device 30 are all disposed in the housing, and the gas generator and the housing are connected to change the gas atmosphere in the inner cavity of the housing; further, the gas generator is a vacuum mechanism or a gas filling mechanism, the vacuum mechanism is a vacuum pump, the vacuum pump is used for pumping gas in the inner cavity of the housing so as to reduce the content of oxygen in the inner cavity of the housing, the gas filling mechanism can be an inert gas source or a carbon dioxide gas source, etc., the gas atmosphere of the inner cavity is changed by filling inert gas or carbon dioxide gas into the inner cavity of the housing, for example, when the inert gas or carbon dioxide gas is filled into the inner cavity, because the molecular weights of the inert gas and carbon dioxide gas are different from the molecular weight of oxygen, the filling of inert gas or carbon dioxide gas into the inner cavity can lead the oxygen in the air to be gathered at the top or the bottom of the inner cavity of the housing, thereby reducing the content of oxygen at the middle position in the inner cavity of the housing, and reducing the influence of oxygen on the printing object positioned in the middle of the inner cavity of, oxygen collected at the top or bottom of the housing can be discharged from the opening, thereby further improving the treatment effect on the surface of the printed object. The following describes a specific structure of the post-processing apparatus with reference to fig. 1, 2, 3, 4, 5, 6, 7, and 8, taking a three-dimensional printed object as an example:
fig. 1 shows a structural plan view of a post-processing apparatus provided in an embodiment of the present application, further, the post-processing apparatus includes a moving device 10, a coating device 20, a curing device 30 and a fixing device 14, in this embodiment, the moving device 10 includes a rotating platform 11, at least one fixing device 14 is fixedly disposed on the rotating platform 11, the fixing device 14 is used for placing a three-dimensional printed object, the coating device 20 and the curing device 30 are disposed around the rotating platform 11 at intervals along a rotating direction of the rotating platform 11, the rotating platform 11 rotates to enable the fixing device 14 to pass through the coating device 20 and the curing device 30 in sequence, that is, when the three-dimensional printed object is placed on the fixing device 14, the rotating platform 11 rotates to enable the three-dimensional printed object placed on the fixing device 14 to pass through the coating device 20 in sequence so that the coating device 20 coats a material on the surface of the three-dimensional printed object, and the material coated on the surface of the three-dimensional printed object is solidified by the solidifying device 30 through the solidifying device 30, so that the surface treatment operation of the three-dimensional printed object is realized, the post-treatment automation of the three-dimensional printed object is realized, and the treatment efficiency and the treatment effect are improved. Wherein, rotary platform 11 can be connected with the motor through the pivot, and through motor drive rotary platform 11 rotatory.
In order to further improve the processing efficiency, it is desirable that the coating device 20 and the curing device 30 can simultaneously perform corresponding operations on different three-dimensional printed objects, and avoid the mutual influence between the coating device 20 and the curing device 30, a partition 111 is provided on the rotary platform 11, the partition 111 is fixedly connected with the rotary platform 11, a partition is formed between two adjacent partitions 111, and the fixing device 14 is provided in the partition. The partition 111 is used for dividing the upper surface of the rotary platform 11 into at least two sections, at least one fixing device 14 is respectively arranged in each section, the rotary platform 11 rotates so that each section sequentially passes through the coating device 20 and the curing device 30, and when the coating device 20 performs a coating operation on the three-dimensional printed object of one section, the curing device 30 can perform a curing operation on the three-dimensional printed object of the other section.
Further, the rotary platform 11 may include two zones, one zone is located in a region where the coating device 20 can perform a coating operation, hereinafter referred to as a coating region 42, and the other zone is located in a region where the curing device 30 can perform a curing operation, hereinafter referred to as a curing region 44, during the process, that is, the coating operation and the curing operation can be performed on different three-dimensional printed objects placed in the two zones, respectively, simultaneously, thereby further improving the process efficiency.
Further, in order to more conveniently load unprocessed three-dimensional printed objects and unload processed three-dimensional printed objects, the rotary table 11 may be further divided into three sections, one section being located in the coating area 42, one section being located in the curing area 44, and the other section being located in an area where the three-dimensional printed objects are loaded and unloaded, hereinafter referred to as the loading area 41 or the unloading area 45 (loading and unloading area) during the processing, so that the coating apparatus 20 and the curing apparatus 30 can continue to perform the coating operation and the curing operation on the three-dimensional printed objects in the other sections while the three-dimensional printed objects to be processed are loaded and the processed three-dimensional printed objects are unloaded, thereby further improving the processing efficiency.
In this embodiment, since the speed of loading and unloading the three-dimensional object is high, the loading and unloading of the three-dimensional printed object in the same area does not affect the processing rate, and therefore, the three-dimensional printing object can be loaded and unloaded in the loading and unloading area in sequence, that is, when the loading and unloading of the three-dimensional printing object in the loading and unloading area in sequence can affect the processing rate, the rotary table 11 may be divided into four sections, one section being located at the loading area 41 to load an unprocessed three-dimensional printed object, one section being located at the coating area 42 to perform a coating operation, one section being located at the curing area 44 to perform a curing operation, one section being located at the unloading area 45 to unload a processed three-dimensional printed object, so that the three-dimensional printed object in different divisional areas can be simultaneously subjected to loading and unloading operations at the loading area 41 and the unloading area 45, respectively.
Furthermore, in order to improve the uniformity of the material coated on the surface of the three-dimensional printed object, it is usually necessary to level the material coated on the surface of the three-dimensional printed object before curing, and therefore, it may be necessary to stay in the coating area 42 for a certain time to complete leveling after the material is coated on the surface of the three-dimensional printed object, or wait for a certain time to complete leveling after the three-dimensional printed object enters the curing area 44, which limits the usage rates of the coating device 20 and the curing device 30, and may hinder the improvement of the processing efficiency, at this time, the rotary platform 11 may be divided into four sub-areas, and the leveling area 43 is disposed between the coating area 42 and the curing area 44, so that the three-dimensional printed object after coating operation can complete leveling in the leveling area 43, and the loading and unloading of the three-dimensional printed object are successively completed in the unloading area 45, under the condition, the higher processing efficiency is still ensured on the premise of improving the processing effect.

Further, after the fixing device 14 with the three-dimensional printed object placed thereon performs the coating operation in the coating area 42, the rotating platform 11 rotates by a certain angle, so that the curing mechanism enters the leveling area 43, and after the curing mechanism enters the leveling area 43, the curing mechanism stands for a period of time in the leveling area 43 or performs centrifugal drying treatment on the three-dimensional printed object with a material applied on the surface, so as to obtain a better and more uniform material coating effect, wherein the centrifugal drying treatment refers to that the three-dimensional printed object rotates at a certain speed, and how to implement centrifugal drying is described below in conjunction with a specific structure of the fixing device 14.
Further, as shown in fig. 4 and 5, the fixing device 14 includes a base 141, a support part 142 is disposed on the base 141, the support part 142 includes support columns disposed perpendicular to a surface of the base 141, the support columns may be fixed on the surface of the base 141, at least three support columns may be disposed, the support columns are used for supporting the three-dimensional printed object, in order to enable the coating device 20 and the curing device 30 to uniformly coat and uniformly cure the three-dimensional printed object placed on the fixing device 14, the base 141 may be a rotatable support plate, that is, while the coating mechanism 21 and the curing lamp 32 process the three-dimensional printed object placed on the base 141, the base 141 rotates, so that the three-dimensional printed object placed on the base 141 can be rotated with respect to the coating mechanism 21 and the curing lamp 32, also, the centrifugal drying process as above may be realized by the rotation of the rotatable base 141; the supporting column is an elastic supporting column and can be an elastic thimble, the elastic thimble comprises a thimble shell with a cavity, an elastic part and a silica gel block, the elastic part and the silica gel block are arranged in the cavity, one end of the silica gel block is connected with the elastic part, the other end of the silica gel block is used for contacting with a three-dimensional printing object, and the elastic part can be deformed by the pressure of the three-dimensional printing object placed on the supporting column on the silica gel block, so that the supporting column is adjustable in height and can better and more stably support the three-dimensional printing objects with different shapes.
Further, the fixing device 14 may further include a tray 143, the base 141 is disposed in the tray 143, and the rotation of the base 141 may be achieved by the rotation of the base 141 itself or by the rotation of the tray 143, specifically, the base 141 and the mobile device 10 are rotatably connected through a rotating shaft, and the tray 143 is fixedly connected with the mobile device 10; the tray 143 may be rotatably coupled to the mobile device 10 by a rotation shaft, and the tray 143 may be fixedly coupled to the base 141. When the three-dimensional printed object placed on the base 141 is processed by the coating mechanism 21 and the curing lamp 32, the three-dimensional printed object placed on the base 141 can be rotated with respect to the coating mechanism 21 and the curing lamp 32 by the rotation of the base 141, and the centrifugal spin-drying operation in the leveling region 43 can also be achieved; the height of the sidewall of the tray 143 is higher than the height of the support member 142, so that the material can be prevented from flying out of the tray 143 when the printed object is spin-dried, and the tray 143 can be used to accommodate the waste generated by the coating device 20 during the coating operation and the waste generated by the leveling treatment performed in the leveling area 43.
Further, a plurality of flow guide grooves 144 may be further disposed on the base 141, the plurality of flow guide grooves 144 are disposed through the base 141, and the material dropped onto the base 141 in the coating operation and the leveling operation may flow into the tray 143 along the flow guide grooves 144; furthermore, in order to facilitate the discharge of the waste material in the tray 143, at least one second channel 146 is disposed at the bottom of the tray 143, the second channel 146 is a waste material recycling channel for discharging the material in the tray 143, the second channel 146 is communicated with the upper surface of the tray 143, and the waste material collected by the tray 143 can be discharged through the second channel 146.

In particular, the first channel 145 may be used to inject a cleaning fluid into the tray prior to curing the three-dimensional printed object. The cleaning liquid may flow to the upper surface of the base 141 through the first passage 145, thereby washing the uncured material remaining on the base 141 clean, and may flow into the tray 143, thereby discharging the fixture 14 through the second passage 146 communicating with the bottom surface of the tray 143; the first channel 145 can also be used for injecting a polymerization inhibitor into the tray 143 before curing the three-dimensional printed object, and the polymerization inhibitor can enter the tray 143 through the first channel 145, so that the liquid level of the polymerization inhibitor is higher than the position of the support component 142, which is in contact with the printed object, thereby preventing the printed object and the support component 142 from being bonded in the curing process and reducing the post-treatment effect of the printed object; however, in the above process, the coating and curing operations cannot be performed on the portion of the printed object covered with the polymerization inhibitor, and therefore, it is necessary to perform the post-treatment operations twice as above on the same printed object, perform the treatment on the portion of the printed object not covered with the polymerization inhibitor during the first post-treatment operation, and perform the second post-treatment operation after turning the printed object upside down to perform the treatment on the portion of the printed object covered with the polymerization inhibitor during the first post-treatment operation. Also, the polymerization inhibitor may be discharged through the second passage 146. The polymerization inhibitor is a material capable of preventing the material from polymerizing, and specifically, in this embodiment, the polymerization inhibitor is a material capable of preventing the light-curable material from curing.
