Description

Technical Field

[0001] The present invention relates to the technical field of dirt prevention and removal, and in particular to a dirt prevention and removal device for maintaining a forming platform of a 3D printer. Background Art

[0002] Fouling prevention is the process of maintaining cleanliness by removing undesirable substances through various methods and measures.

[0003] 3D printing, also known as additive manufacturing, is a process that builds three-dimensional objects by stacking materials layer by layer. This technology first appeared in the 1980s, and with the advancement of time and technology, it has become an important tool in manufacturing, biomedicine, architecture and many other fields. The main advantages of 3D printing technology include high design flexibility, strong customized production capabilities, fast molding speed and the ability to print with a variety of materials. In a 3D printer, the build platform is a critical component that provides a precise base for materials to be stacked layer by layer to form complex three-dimensional structures. The stability and maintenance of the build platform directly affect the print quality, including the accuracy, adhesion and overall appearance of the print.

[0004] If there is dirt or residue on the building platform, the printed object may not be properly attached or may fall off. In addition, if there is any foreign matter on the building platform, the distance between the print head and the platform will be inconsistent, which may cause the print head to collide or be too far away from the platform, resulting in printing failure. There are many situations that lead to dirt or residue on the building platform. For example, during the fused deposition 3D printing process, extra plastic filaments may be left on the platform surface due to the movement of the extruder head or the cooling of the material. When printing specific materials such as ABS, adhesives or glues may be used to help adhere the model, and these substances may also remain on the platform. Fibers and small fragments around the printer may also adhere to the platform. In addition, the demolding operation after each print is completed may also cause scratches on the platform surface. Although it is not "dirt" in the traditional sense, wear and scratches on the platform surface are also a kind of damage.

[0005] Although the importance of the build platform is self-evident, its maintenance is challenging. Currently, the maintenance tools and equipment for 3D printer build platforms are still relatively limited, and most solutions rely on manual operations. For frequent industrial printing, cleaning is required after each print, and a lot of dirt is difficult to handle. Therefore, the maintenance of the build platform is a time-consuming and labor-intensive process, which will significantly reduce production efficiency. In addition, manual operations are often based on experience, and it is very easy to have incomplete cleaning, resulting in inadequate maintenance or damage to the build platform due to improper operation.

[0062] The push-off portion 7 is located below the shower cleaning portion 6, wherein:

[0063] The double-layer loading plate 5 is in an upper protruding shape, so that the liquid spraying cleaning part 6 is generally located in front of the pushing part 7, ensuring that when the molding platform 2 is cleaned and maintained, after the liquid spraying cleaning part 6 and the pushing part 7 are moved to the designated working position on the sliding seat 4, the liquid spraying cleaning part 6 is in contact with the molding platform 2 and the pushing part 7 is not in contact with the molding platform 2, ensuring a strict and orderly working operation sequence and logic, so as to prevent the pushing part 7 from affecting the operation of the liquid spraying cleaning part 6;

[0064] The two groups of the sealing and rapid cooling parts 3 are suitable for forming wind blocking surfaces on the left and right sides of the molding platform 2 to relatively separate the molding platform 2 from the outside;

[0065] The two groups of the sealing screen rapid cooling parts 3 are suitable for vertically cross-blowing the molding platform 2 to accelerate the cooling speed of the peripheral model on the molding platform 2;

[0066] The spray cleaning part 6 and the push-off part 7 are suitable for processing the dirt on the molding platform 2 in turn to restore the cleanliness of the molding platform 2. The two sets of sealing screen quick cooling parts 3 are based on the outer frame of the printer body 1. During printing, a blocking barrier composed of wind can be formed on the left and right sides of the molding platform 2, thereby separating the molding platform 2 from the environment around the printer body 1 to a certain extent, thereby effectively reducing the fibers and small fragments floating and attached to the molding platform 2, and minimizing the impact on printing. The two sets of sealing screen quick cooling parts 3 can quickly switch the wind direction after printing. , thereby cross-blowing the molding platform 2 and the model thereon, greatly improving the flow speed of the airflow around the molding platform 2 and the model, and then quickly taking away the heat, effectively improving the cooling speed of the just-printed model, ensuring that the model can reach a temperature that can be removed in a shorter time, and ensuring a good preventive function to prevent the staff from forcibly removing the model in advance due to mistaken operation, resulting in damage to the molding platform 2. The liquid cleaning part 6 can automatically spray the cleaning agent along the longitudinal and transverse directions of the molding platform 2, so that the cleaning agent required for removing dirt is sprinkled on the molding platform 2, so that the dirt on the molding platform 2 can be removed. The plastic filaments, such as the plastic filaments, the plastic filaments and the plastic filaments on the molding platform 2 are completely or partially pried up, and the plastic filaments and the plastic filaments on the molding platform 2 are completely or partially separated from the surface of the molding platform 2. At the same time, the pushing and removing part 7 can also perform a covering pushing and shoveling along the surface of the molding platform 2, so as to completely push away all kinds of dirt that have been completely or partially separated from the molding platform 2. In addition, when removing dirt, the pushing and removing part 7 can also synchronously wipe the surface of the molding platform 2, so as to remove the dirt. In addition to removing tiny residual dirt and liquid traces, thereby ensuring the thoroughness of the removal of various dirt and restoring the cleanliness of the surface 2 of the forming platform, the anti-removal equipment used for the maintenance of the forming platform of the 3D printer strictly follows the established standards for the removal of dirt, can achieve excellent cleaning and removal effects and ensure that the forming platform 2 will not be artificially damaged due to improper operation, while ensuring that maintenance and cleaning are in place while taking into account reliability, and at the same time greatly reducing the steps that need to rely on manual operation by staff, effectively improving the efficiency of cleaning and maintenance, greatly reducing the consumption of time and labor, and thus ensuring production efficiency.

[0067] Optionally, the liquid sprinkling cleaning part 6 includes a first electric cylinder 61 installed on the double-layer loading plate 5, two bent bifurcated rods 62 respectively installed on both sides of the double-layer loading plate 5 and used to fix foreign objects, two wall panels 63 respectively installed at the ends of the two bent bifurcated rods 62, a conjoined plate 64 respectively slidably installed on the top of the two wall panels 63, a concave thin plate 65 connected to the two concave thin plates 64, and a linear module 66 arranged on the bottom surface of the concave thin plate 65, and the linear module 66 can specifically be a ball screw The linear module, the slider linear module, the gear linear module, etc. can drive the square box 68 to reciprocate to spray the detergent. The conjoined column 67 installed on the linear module 66, the square box 68 connected to the conjoined column 67, the spray port 69 connected to the inner space of the square box 68 from the bottom, the two first force arms 691 connected to the output end of the first electric cylinder 61 and respectively installed on the left and right ends of the concave thin plate 65, and the bucket-shaped member 692 detachably installed on the square box 68, wherein:

[0068] The two wall panels 63 are suitable for respectively contacting with the two side surfaces of the forming platform 2;

[0069] The square box 68 is suitable for storing cleaning agents. Suitable cleaning agents are selected according to the specific solidified dirt on the forming platform 2. When the forming platform 2 needs to be maintained and cleaned, the liquid sprinkling cleaning part 6 is moved to the front as a whole through the sliding seat 4, so that the two wall panels 63 are respectively attached to the two side surfaces of the forming platform 2, and then the first electric cylinder 61 is driven to push the two connected plates 64 and the concave thin plate 65 forward on the top of the two wall panels 63 through the two first force arms 691, and at the same time, the linear module 66 is synchronously driven to drive the square box 68 to start reciprocating motion above the forming platform 2 through the connected column 67. The cleaning agent in the square box 68 is sprinkled downward through the liquid sprinkling port 69, and the cleaning agent is sprinkled on different positions on the forming platform 2 in a large range during the movement, so that the cleaning agent required for removing dirt is sprinkled on the forming platform 2, so that the dirt on the forming platform 2 can be dissolved or softened under the action of the cleaning agent, thereby providing conditions for subsequent removal work. The bucket-shaped member 692 is provided with a detachable assembly method, and it is removed immediately after adding the cleaning agent, so that it will not move back and forth with the square box 68 and collide with the first force arm 691; the two wall panels 63 are attached to the two sides of the forming platform 2 to form a barrier in the corresponding direction, thereby preventing the cleaning agent sprinkled on the forming platform 2 from flowing out; the working coordinates of the anti-removal equipment for maintaining the forming platform of the 3D printer, such as the spray cleaning part 6 and the push-off part 7, are all set with the original position of the forming platform 2 as the reference point, that is, when maintaining and cleaning the forming platform 2, it must first be reset, so as to ensure that the two wall panels 63 can be accurately attached to the two side surfaces of the forming platform 2 and ensure that the bottom surface of the erasing member 77, the plurality of spikes 74, and the shovel plate 76 is flush with the surface of the forming platform 2 for maintenance and cleaning work, so as to prevent damage to the forming platform 2.

[0070] Optionally, the push-off portion 7 includes a second electric cylinder 71 installed on the double-layer load-bearing plate 5, two second force arms 72 installed on the output end of the second electric cylinder 71, a horizontal plate 73 with two ends respectively connected to the two second force arms 72, and a plurality of spikes 74 installed at equal intervals in front of the horizontal plate 73;

[0071] The horizontal plate 73 is as wide as the molding platform 2. After the liquid cleaning part 6 finishes spraying on the molding platform 2, the second electric cylinder 71 is driven to push the horizontal plate 73 and the plurality of spikes 74 forward through the two second force arms 72, so that the plurality of spikes 74 are closely attached to the surface of the molding platform 2 and pushed forward. The plurality of spikes 74 are used to pry the bottom of the plastic wire, glue, etc. fixed on the surface of the molding platform 2, thereby causing them to be completely or partially separated from the surface of the molding platform 2, so that the stubborn dirt on the molding platform 2 is separated from the molding platform 2 to varying degrees.

[0072] The bottom of the several spike members 74 is flat, and while maintaining a sharp front end, ensuring the separation performance of dirt, it is ensured that the several spike members 74 are in surface contact with each other when they move forward on the forming platform 2 to prevent scratches on the surface of the forming platform 2, and the bottom surface of the several spike members 74 is on the same horizontal plane as the surface of the forming platform 2. After the forming platform 2 is reset, a laser transmitter or the like can be used to calibrate the position of the several spike members 74 and the forming platform 2.

[0073] Optionally, the push-off portion 7 further includes a plurality of rectangular thin plates 75 hinged at one end to the transverse plate 73, and the plurality of rectangular thin plates 75 are respectively located on the gaps between the plurality of spikes 74, and a shovel plate 76 connected to the other end of the plurality of rectangular thin plates 75, wherein:

[0074] The plurality of rectangular thin plates 75 are rotated forward to gradually move the shovel plate 76 downward so that the shovel plate 76 is rotated to the front of the plurality of spike members 74. When the plurality of spike members 74 are working, the plurality of rectangular thin plates 75 and the shovel plate 76 are erected. After the plurality of spike members 74 complete the corresponding work and reset, the plurality of rectangular thin plates 75 and the shovel plate 76 are rotated downward until the shovel plate 76 is rotated to the front of the plurality of spike members 74. Then, the second electric cylinder 71 is driven again to push the cross plate 73 forward. At this time, the shovel plate 76 is used to shovel and push in a covering manner against the surface of the forming platform 2. The shovel plate 76 is used to push the dirt that has been dissolved, softened and separated by the prying away from the forming platform 2, thereby improving the efficiency of cleaning and maintenance and greatly reducing the time and labor consumption. Due to the presence of the two wall panels 63, the two ends of the shovel plate 76 will be pushed forward against the two wall panels 63, and the two wall panels 63 are used to prevent the dirt from moving outside the forming platform 2.

[0075] Optionally, the sealing and quick cooling part 3 includes a plurality of positioning members 31 arranged on the outer frame of the printer body 1 and used to fix external objects, a long cylinder 32 arranged on the plurality of positioning members 31, a central core column 33 rotatably mounted on the inner bottom surface of the long cylinder 32, and the top surface of the central core column 33 is in contact with the inner top surface of the long cylinder 32, a partition 34 installed on the central core column 33 and dividing the inside of the long cylinder 32, a semicircular plate 35 installed on the central core column 33 and in contact with the bottom of the partition 34, a first air outlet 36 opened on the long cylinder 32, and an air supply pipe 37 one end of which is connected to the long cylinder 32;

[0076] The air supply pipe 37 is located below the semicircular plate 35, and the other ends of the air supply pipes 37 of the two sets of sealing screen rapid cooling parts 3 are connected to the blowing port of the external blower through the same joint. Before printing, the external blower is started to allow the air to reach the long cylinder 32 through the air supply pipe 37 and be blown out through the first air outlet 36, so that under the action of the two sets of sealing screen rapid cooling parts 3, a blocking barrier composed of wind is formed on the left and right sides of the forming platform 2 throughout the whole process, which to a certain extent separates the forming platform 2 from the environment around the printer body 1, thereby effectively reducing the fibers and small fragments floating and attached to the forming platform 2, and minimizing the impact on printing, so as to achieve good protection and prevention functions.

[0077] Optionally, the sealing and quick cooling part 3 further includes a motor 38 installed on the top of the long cylinder 32, a second air outlet 39 provided on the long cylinder 32, a first guide plate 391 installed on the outer wall of the long cylinder 32 and respectively close to both sides of the first air outlet 36, and a second guide plate 392 installed on the outer wall of the long cylinder 32 and respectively close to both sides of the second air outlet 39;

[0078] The output end of the motor 38 passes through the long cylinder 32 and is connected to the central core column 33. During actual printing, the molding platform 2 often works at a relatively high temperature, and the temperature of the model just printed is also relatively high. The bonding force between the model and the molding platform 2 will remain strong at a relatively high temperature. If the model is not completely cooled, forcibly removing it will easily damage the molding platform 2. Under normal circumstances, the partition 34 and the semicircular plate 35 are both on the right side of the first air outlet 36. The partition 34 and the semicircular plate 35 are used to close the space on one side of the second air outlet 39 in the long cylinder 32 to prevent wind from entering, and only introduce wind into the side of the first air outlet 36. After printing is completed, the motor 38 is driven to drive the central core column 33, the partition 34 and the semicircular plate 35 to rotate in the long cylinder 32, and adjust their positions so that the partition 34 and the semicircular plate 35 are The circular plate 35 closes the space on one side of the long cylinder 32 where the first air outlet 36 is located, thereby preventing wind from entering the space on one side where the first air outlet 36 is located and prompting wind to enter the space on one side where the second air outlet 39 is located and blow out from the second air outlet 39, so as to achieve the purpose of quickly switching the blowing direction. Then, under the action of the two sets of sealing and quick cooling parts 3, the forming platform 2 and the model thereon are blown crosswise, greatly improving the flow speed of the airflow around the forming platform 2 and the model, quickly taking away the heat, effectively speeding up the cooling speed of the just-printed model, ensuring that the model can reach a temperature that can be removed in a shorter time, so as to prevent the staff from forcibly removing the model in advance due to mistaken operation, thereby causing damage to the forming platform 2, improving the fault tolerance rate, further achieving good protection and prevention functions, and controlling the difficulty of maintenance and cleaning as much as possible;

[0079] The two first guide plates 391 are arranged parallel to the side of the forming platform 2. The two first guide plates 391 guide the wind blown out from the first air outlet 36 forward in a direction parallel to the side of the forming platform 2, thereby ensuring the quality of the formed blocking barrier to achieve a better blocking effect.
