[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figure 1-4 The present invention provides the following technical solution: an automatic cleaning device for 3D additive manufacturing, including a cleaning tank 1, a filter box assembly 6 fixedly installed below the cleaning tank 1, water pump assemblies 4 fixedly installed on both sides of the filter box assembly 6, multiple nozzles 3 fixedly installed on one side of the top of the water pump assembly 4 and located inside the cleaning tank 1, a position adjustment lighting device 2 fixedly installed near the top of the cleaning tank 1, and a drying treatment device 5 fixedly installed below the filter box assembly 6.

[0021] Specifically, the positioning lighting device 2 includes a bracket 21, a waterproof shell 22, an electric telescopic rod 23, a mesh plate 24, a mesh frame 25, a rotating lighting component 26, and an electric lifting rod 27. The bracket 21 is fixedly installed above the cleaning tank 1. The electric lifting rod 27 is fixedly installed on the top of the bracket 21. The mesh frame 25 is provided below the electric lifting rod 27. The waterproof shell 22 is fixedly installed on both sides of the mesh frame 25. The electric telescopic rod 23 is fixedly installed on the inner side of the waterproof shell 22. The mesh plate 24 is fixedly installed on one side of the electric telescopic rod 23 and located inside the mesh frame 25. The electric lifting rod 27 and the mesh frame 25 are connected by the rotating lighting component 26.

[0022] By adopting the above technical solution, staff can adjust the height of the printed parts when needed using the electric lifting rod 27 and other structures, thereby enabling the device to clean the printed parts at different heights.

[0023] Specifically, the rotating lighting assembly 26 includes a geared motor 261 and a transparent shell 263. The transparent shell 263 is fixedly installed on the side of the electric lifting rod 27 near the mesh frame 25. The mesh frame 25 and the transparent shell 263 are connected by the geared motor 261.

[0024] By adopting the above technical solution, staff can adjust the angle of the printed parts when needed by using the geared motor 261 and other structures, so that the device can clean the printed parts at different angles.

[0025] Specifically, the rotating lighting assembly 26 also includes lighting lamps 262, and multiple lighting lamps 262 are fixedly installed on the inside of the transparent shell 263.

[0026] By adopting the above technical solution, staff can use the lighting lamp 262 to provide some auxiliary lighting when needed, thereby better coping with some situations of insufficient light and ensuring the normal progress of work.

[0027] In this embodiment, when the 3D additive manufacturing process requires automatic cleaning of the printed parts, the operator pours enough water into the cleaning tank 1, which then enters the filter assembly 6. The operator then places the printed part into the mesh frame 25 in the positioning lighting device 2, activates the electric telescopic rods 23 in the two waterproof shells 22, which in turn drive the two mesh plates 24 to clamp the printed part, and then activates the two water pump assemblies 4 to pump water. The water is then sprayed from each nozzle 3 onto the printed part, thus performing automatic cleaning. During the cleaning process, the operator can activate the electric lifting rod 27 on the bracket 21 to move the rotating lighting assembly 26 and the mesh frame 25, thereby adjusting the height of the printed part. Alternatively, the operator can activate the geared motor 261 to rotate the mesh frame 25, thereby adjusting the angle of the printed part. When needed, the operator can activate the various lights 262 inside the transparent shell 263 for auxiliary lighting. Example

[0028] The difference between this embodiment and Embodiment 1 is that the drying device 5 includes a support frame 51, an output pipe 52, a jet nozzle 53, an electric heating rod 54, a fan 55, and a connecting cylinder 56. The support frame 51 is fixedly installed below the filter box assembly 6. The connecting cylinder 56 is fixedly installed on one side of the support frame 51 near its edge. The fan 55 is fixedly installed on the side of the connecting cylinder 56 away from the support frame 51. Multiple electric heating rods 54 are fixedly installed inside the connecting cylinder 56. The output pipe 52 is fixedly installed on the side of the connecting cylinder 56 away from the fan 55. Multiple jet nozzles 53 are fixedly installed below the output pipe 52.

[0029] By adopting the above technical solution, staff can dry the cleaned printed parts when needed using the combination of the fan 55 and the heating rod 54, thereby reducing potential inconvenience.

[0030] Specifically, the drying device 5 also includes a filter screen 57, which is fixedly installed on the inner side of the air inlet end of the fan 55.

[0031] By adopting the above technical solution, the device can prevent external impurities from entering the interior of the fan 55 through the filter screen 57, thereby reducing the possibility of adverse effects on the structure such as the fan 55 and the electric heating rod 54, and thus ensuring normal operation.

[0032] In this embodiment, after cleaning, the operator can place the cleaned printed parts under each jet nozzle 53 in the support frame 51 of the drying device 5. Then, the blower 55 and each heating rod 54 are started. The blower 55 sends the air filtered by the filter screen 57 into the connecting cylinder 56. Each heating rod 54 heats the air. Then, the hot air passes through the output pipe 52 and is sprayed from each jet nozzle 53 onto the printed parts, thereby drying them and reducing possible inconvenience.

[0033] The structure and principle of the cleaning box 1 and its upper structure, the nozzle 3, the water pump assembly 4 consisting of an inlet pipe, a booster water pump, and an outlet pipe, and the filter box assembly 6 consisting of a slot, a fixing block, a filter box, a filter screen, a slider, a slide groove, a spring, a locking block, a limiting rod, a limiting groove, and a mounting plate have been disclosed in Chinese Patent Application No. 202420996537.7, which discloses an automatic cleaning device for 3D additive manufacturing. Its working principle is as follows: First, the printed part is placed on top of the placement plate. Then, the motor output shaft is started to automatically drive the bidirectional lead screw to rotate, simultaneously causing the displacement block to slide outside the slide rod. The slide rod can then limit the movement of the displacement block, thus preventing displacement from shifting. Next, the movement of the displacement block causes the clamping plate to move closer to the outside of the printed part, completing the fixation of the printed part and increasing the stability of the printed part during rinsing. Finally, the nozzle cleans the printed part... The outer side of the component is rinsed, and the wastewater generated during rinsing flows through the through-hole into the top of the filter screen inside the filter box. The wastewater is then filtered through the filter screen, and the filtered water is then pumped by a booster pump from the outlet and inlet pipes into the nozzle, thus forming a circulating rinse, which saves water resources. When replacing or cleaning the filter screen, the limiting rod slides inside the limiting groove, which in turn moves the slider inside the sliding groove. This causes the locking block to disengage from the slot, thus releasing the mounting plate. The filter screen can then be easily pulled out from inside the filter box. When installing the filter screen, one side of the mounting plate abuts against the inclined surface of the locking block, causing the locking block to slide and the slider to move, compressing the spring. Then, when the slot moves to one side of the locking block, the reaction force of the spring causes the locking block to directly enter the slot, thus automatically fixing the mounting plate.

[0034] The working principle and usage process of this utility model are as follows: When 3D additive manufacturing requires automatic cleaning of the printed parts, the operator pours enough water into the cleaning tank 1, which then enters the filter assembly 6. The operator then places the printed part into the mesh frame 25 of the positioning lighting device 2, activates the electric telescopic rods 23 in the two waterproof shells 22, which in turn move the two mesh plates 24 to clamp the printed part. Then, the two water pump assemblies 4 are activated to pump water, which is then sprayed from each nozzle 3 onto the printed part, thus performing automatic cleaning. During the cleaning process, the operator can activate the electric lifting rod 27 on the bracket 21 to move the rotating lighting assembly 26 and the mesh frame 25, thereby adjusting the position of the printed part. The height of the printed parts can be adjusted by starting the geared motor 261, which drives the mesh frame 25 and other structures to rotate, thereby adjusting the angle of the printed parts. When needed, the staff can turn on the lights 262 inside the transparent shell 263 for auxiliary lighting. After cleaning, the staff can place the cleaned printed parts under the air jets 53 in the support frame 51 of the drying device 5, and then start the fan 55 and the heating rods 54. The fan 55 sends the air filtered by the filter screen 57 into the connecting cylinder 56, and the heating rods 54 heat the air. Then the hot air passes through the output pipe 52 and is sprayed from the air jets 53 onto the printed parts to dry them, reducing possible inconvenience.
