Description

Technical Field

[0001] The present invention belongs to the technical field of additive manufacturing, and in particular relates to a digital additive manufacturing quality control device. Background Art

[0002] With the rapid development of science and technology, additive manufacturing (AM), especially laser powder printing technology, has become an indispensable part of modern manufacturing. This technology builds three-dimensional objects by stacking materials layer by layer, greatly expanding the freedom of product design and realizing the direct manufacturing of complex structures. However, although additive manufacturing technology has shown great potential and advantages in many fields, the quality control of its finished products is still a major bottleneck restricting its widespread application.

[0003] First, during the laser powder printing process, a high-energy laser beam scans the surface of the material, causing the powder to melt and solidify into the desired shape. However, during this process, the laser beam not only acts on the target area, but the heat it emits may also affect the surrounding powder that is not directly irradiated, causing these powders to partially melt or soften, and then forming burrs, bumps and other abnormal shapes on the surface of the finished product. These defects not only affect the appearance of the product, but may also have a serious impact on its functionality and durability.

[0004] Secondly, during the additive manufacturing process, due to the characteristics of material accumulation layer by layer, the structural strength of the printed parts is often weak in the initial stage of manufacturing and is easily affected by external environmental factors (such as temperature fluctuations, vibrations, etc.), causing the printed parts to deform or shift during the manufacturing process, thereby affecting the dimensional accuracy and shape consistency of the final product.

[0005] In view of the various problems that may arise during the additive manufacturing process, it is particularly important to monitor and adjust the printed parts in all directions and from multiple angles. Traditional quality control methods often rely on manual inspection and manual correction, which is not only inefficient but also difficult to achieve high precision requirements.

DETAILED DESCRIPTION

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0048] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0049] Please refer to the attached Figure 1-Figure 18As shown, this embodiment provides a digital additive manufacturing quality control device, including a processing table 10, a driving component 11 is arranged on the top of the processing table 10, a regulating component 12 is arranged on the driving component 11, a grinding component 13 is arranged at the bottom of the regulating component 12, and a detection component 14 is arranged on the top of the driving component 11;

[0050] A placement assembly 20, the placement assembly 20 includes a turntable assembly 21 disposed on the processing table 10, a rotating assembly 22 is disposed at the bottom of the turntable assembly 21, a clamping assembly 23 is disposed at the top of the turntable assembly 21, and a flipping assembly 24 is disposed inside the clamping assembly 23;

[0051] Among them, after the additively manufactured finished product is placed on the turntable assembly 21, the clamping assembly 23 moves along the turntable assembly 21 to clamp the finished product, and drives the finished product to rotate through the rotating assembly 22. The detection assembly 14 detects the shape of the finished product, and after the detection is completed, the finished product is trimmed by the polishing assembly 13. The regulating assembly 12 is used to drive the polishing assembly 13 to rotate as a whole;

[0052] The turning assembly 24 is used to turn over the finished product, and the turntable assembly 21 is used to vibrate the finished product or adjust the tilt angle of the finished product.

[0053] In this embodiment, after placing the finished product manufactured by additive manufacturing on the turntable assembly 21, the clamping assembly 23 will run quickly to clamp the finished product tightly. When the finished product needs to be flipped, the user only needs to lift the lifting and lowering part of the flip assembly 24 to drive the finished product to rise together. Subsequently, the user can realize flip detection by controlling the rotation of the finished product. During the detection process, the rotating assembly 22 can easily adjust the orientation of the turntable assembly 21 and the finished product to meet different detection requirements. Another important function of the turntable assembly 21 is to control the tilt angle of the finished product and produce a vibration effect. Through the operation of the telescopic part of the turntable assembly 21, one side of the turntable assembly 21 can be pushed up to adjust the tilt angle of the turntable assembly 21 and the finished product. When the tilt adjustment is performed continuously and quickly, a certain vibration will be generated. This vibration effect can effectively simulate various vibration conditions that the finished product may suffer in the actual use environment, thereby more comprehensively detecting the stability and reliability of the finished product. During the detection, the drive assembly 11 will drive the detection assembly 14 to completely scan the shape and size of the finished product to ensure that the quality of the finished product meets the design requirements. If there is something unusual, the driving component 11 and the regulating component 12 can also drive the grinding component 13 to grind the unusual part. During the grinding process, the dust collecting part of the grinding component 13 can absorb the generated dust in real time to keep the working environment clean and hygienic.

[0054] Next, please refer to Figure 1-Figure 6The driving assembly 11 includes brackets 111 fixedly connected to the front and rear sides of the top of the processing table 10, the tops of the two sets of brackets 111 are fixedly connected to the first electric guide rail 112, the first electric guide rail 112 is slidably connected to the assembly plate 113, and the assembly plate 113 is fixedly connected to the second electric guide rail 114;

[0055] The regulating component 12 includes a first electric push rod 121 slidably connected to the inner cavity of the second electric guide rail 114 located at the rear side, the bottom of the first electric push rod 121 is fixedly connected to a fixed plate 122, the middle of the fixed plate 122 is rotatably connected to a rotating frame 123, the left end of the rotating frame 123 extends out of the fixed plate 122 and is fixedly connected to a guide rod 124, the guide rod 124 is slidably connected to the left side of the fixed plate 122, the top of the left side of the fixed plate 122 is rotatably connected to a second electric push rod 125, and the bottom of the second electric push rod 125 is rotatably connected to the top of the guide rod 124;

[0056] The grinding assembly 13 includes a first motor 131 fixedly connected to the rotating frame 123, a grinding wheel 132 is fixedly connected to the output shaft of the first motor 131, a dust suction nozzle 133 is fixedly connected to the middle of the rotating frame 123, a fan 134 is fixedly connected to the top of the second electric guide rail 114 located at the rear side, the inlet and outlet of the fan 134 are both connected to the air duct 135, the air duct 135 at the inlet is connected to the dust suction nozzle 133, and the air duct 135 at the outlet is connected to the dust collection box 136, and the dust collection box 136 is fixedly connected to the assembly plate 113 located at the rear side;

[0057] The detection assembly 14 includes a mounting frame 141 slidably connected to the second electric guide rail 114 located at the front side, and an infrared scanner 142 is fixedly connected to the bottom of the mounting frame 141 .

[0058] It should be noted that an air outlet is provided at the rear side of the dust box 136, and a filter is provided in the air outlet, so as to collect dust in the dust box 136;

[0059] An arc groove is formed on the left side of the fixing plate 122, and the top right side of the guide rod 124 is slidably connected in the arc groove;

[0060] A semicircular metal block is provided at the bottom center of the grinding wheel 132 to facilitate subsequent tapping inspection of the finished product.

[0061] In this embodiment, when performing the inspection, the user can control the mounting frame 141 to slide to the appropriate position along the second electric guide rail 114 by operating the control panel or using the remote control, and the first electric guide rail 112 on the front side also drives the mounting frame 141 to move horizontally, so that the infrared scanner 142 can completely scan all parts of the finished product, and record the shape and size data of the finished product for analysis. If the analysis results show that there are quality problems with the finished product, such as dimensional deviation, irregular shape, etc., the first electric push rod 121 will slide accurately along the second electric guide rail 114 and the first electric guide rail 112 on the rear side, thereby driving the entire grinding assembly 13 to move to the problem area of ​​the finished product and pushing the grinding wheel 132 close to the finished product. At this time, the second electric push rod 125 will adjust the angle of the guide rod 124 as needed, and then change the direction of the rotating frame 123 and the grinding wheel 132 to ensure that the grinding wheel 132 can accurately align with the problem area. Then, the first motor 131 will start, driving the grinding wheel 132 to rotate at high speed, and finely grind the problem area. During the grinding process, the dust suction nozzle 133 absorbs the generated dust in real time and transports it to the dust box 136 through the air duct 135. After the grinding is completed, the first electric push rod 121 can drive the grinding wheel 132 to move up and down continuously, and use the metal block at the bottom of the grinding wheel 132 to continuously knock on the weaker area of ​​the finished part to detect the strength of the finished part.

[0062] Next, please refer to Figure 7-Figure 12 The turntable assembly 21 includes a disk 211 placed in the middle of the processing table 10, a second motor 212 is fixedly connected to the bottom of the processing table 10, a rotating shaft 213 is fixedly connected to the output shaft of the second motor 212, a ball sleeve 214 is fixedly connected to the top of the rotating shaft 213, and the ball sleeve 214 is rotatably connected to the middle of the bottom surface of the disk 211. The inner circle of the bottom surface of the disk 211 is provided with a limited groove 215. Four sets of third electric push rods 216 are fixedly connected to the top surface of the processing table 10, and the output ends of the third electric push rods 216 are all fixedly connected to metal balls 217;

[0063] The rotating assembly 22 includes a fourth electric push rod 221 fixedly connected to the top of the processing table 10, the top of the fourth electric push rod 221 is fixedly connected to a lifting plate 222, the top of the lifting plate 222 is rotatably connected to a driving ring 223, the top outer ring of the rotating shaft 213 is fixedly connected to a convex strip 224, the driving ring 223 is slidably connected to the outer ring of the convex strip 224, and the inner ring of the bottom surface of the disk 211 is fixedly connected to four groups of driving strips 225, and the driving strips 225 are movably sleeved on the outer ring of the driving ring 223.

[0064] It should be noted that the outer ring of the ball sleeve 214 is provided with a contact-type conductive component (not shown in the figure), and the outer ring of the rotating shaft 213 supplies energy to the ball sleeve 214 through a contact-type power supply component, so that the ball sleeve 214 can send electrical energy into the inside of the disc 211 to supply energy to the subsequent clamping component 23;

[0065] There are four driving bars 225, and the outer ring of the driving ring 223 is also provided with four sets of U-shaped frames. The driving bars 225 are movably sleeved in the U-shaped frames, so that when the driving ring 223 rotates, it can push the driving bars 225 and the disc 211 to rotate. When the disc 211 needs to be tilted, the driving ring 223 can be adjusted to descend and detach from the driving bars 225 to avoid affecting the tilt of the disc 211.

[0066] In this embodiment, when the finished product is placed on the disc 211, the second motor 212 can be started by operating the control panel or using a remote control. The second motor 212 drives the rotating shaft 213 and the driving ring 223 to rotate, and the driving ring 223 drives the driving bar 225 to rotate, thereby driving the disc 211 and the finished product to rotate together to adjust the orientation angle of the finished product. When the tilt angle of the finished product needs to be adjusted, the fourth electric push rod 221 is retracted, and the adjustment lift plate 222 and the driving ring 223 are lowered to separate the driving ring 223 from the driving bar 225 to avoid affecting the tilt of the disc 211. Then, the four groups of third electric push rods 216 adjust their respective heights according to the needs, so that the four groups of metal balls 217 have different heights, thereby pushing the disc 211 to tilt around the ball sleeve 214 as the center to adjust the tilt angle of the finished product. After the disk 211 is tilted, the driving ring 223 rises again, so that one set of U-shaped frames of the driving ring 223 contacts one of the driving bars 225, so that the disk 211 can still be driven to rotate by the driving ring 223 in the tilted state, thereby improving applicability.

[0067] In addition, after the finished product is processed, the tilt angle of the disk 211 can be continuously adjusted to cause vibration of the finished product, and then the strength of the finished product can be tested through vibration to improve applicability.

[0070] The second gear 236 is a gear set composed of two groups of gears, and the outer rings of the two gears of the second gear 236 are connected to the chain 237, and the two groups of chains 237 are respectively connected to the front and rear two groups of bidirectional screw rods 233 and the first gear 234.

[0071] It should be noted that the bottom of the guide groove 231 is an arc-shaped structure, and the disc 211 is provided with a through groove at the bottom of the arc of the guide groove 231, so that the dust entering the guide groove 231 can slide down into the bottom of the inner cavity of the guide groove 231, and it is convenient to clean the inside of the guide groove 231. When cleaning, the dust can be directly discharged from the through groove;

[0072] The toothed block 244 is a semicircular rubber block, and multiple groups of toothed blocks 244 are provided, all of which are rotatably connected to each other, so that when the toothed block 244 encounters a special-shaped finished part, the toothed block 244 will rotate to fit the surface of the finished part, so as to achieve the clamping of the finished parts of different shapes;

[0073] The outer ring of the nut 243 is provided with a handle to facilitate driving the rotation.

[0074] In this embodiment, when the finished product is placed on the disc 211, the third motor 235 drives the second gear 236 to rotate, and drives the two sets of chains 237 to rotate through the second gear 236, and the chains 237 respectively drive the front and rear sets of first gears 234 and the bidirectional screw rod 233 to rotate, driving the mobile frame 232 to move along the track of the guide groove 231, gradually approaching the center of the disc 211, and when the mobile frame 232 moves, the lifting frame 241 and the rotating frame 242 will also move together until the toothed block 244 contacts and clamps the finished product. When the finished product needs to be flipped, the rotating frame 242 is loosened by rotating the nut 243, and then the lifting frame 241 is lifted to raise the rotating frame 242, and then the finished product and the rotating frame 242 are rotated to flip and adjust, and after the adjustment is completed, the lifting frame 241 is put down, and the nut 243 is tightened to fix the rotating frame 242.

[0075] The working principle of the present invention is as follows: when the finished part is placed on the disc 211, the third motor 235 will drive the second gear 236 and the two groups of chains 237 to rotate, and then drive the front and rear two groups of first gears 234 and the bidirectional screw rod 233 to rotate, driving the left and right two groups of moving frames 232 and the rotating frame 242 to approach each other until the toothed block 244 contacts and clamps the finished part. The user can control the movement of the mounting frame 141 through the second electric guide rail 114 and the first electric guide rail 112 on the front side by operating the control panel or using a remote control, so that the infrared scanner 142 can completely scan all parts of the finished part, and record the shape and size data of the finished part for analysis. When the finished product is inspected, the second motor 212 drives the rotating shaft 213 and the driving ring 223 to rotate, and then drives the driving bar 225, the disc 211 and the finished part to rotate together, and adjusts the orientation angle of the finished product. When the tilt angle of the finished product needs to be adjusted, the fourth electric push rod 221 adjusts the driving ring 223 to descend, so that the driving ring 223 is separated from the driving bar 225 to avoid affecting the tilt of the disc 211. Then the four groups of third electric push rods 216 adjust their respective heights according to the needs, so that the four groups of metal balls 217 have different heights, thereby pushing the disc 211 to tilt around the ball sleeve 214 as the center, and adjusting the tilt angle of the finished product. When the finished product needs to be flipped, the rotating frame 242 is loosened by rotating the nut 243, and then the lifting frame 241 is lifted to raise the rotating frame 242, and then the finished product is rotated to flip and adjust. After the inspection, the analysis results show that the finished product has quality problems, such as dimensional deviation, irregular shape, etc. The first electric push rod 121 will accurately move through the second electric guide rail 114 and the first electric guide rail 112 on the rear side, drive the grinding assembly 13 to move to the problem area of ​​the finished product, and push the grinding wheel 132 close to the finished product. At this time, the second electric push rod 125 will adjust the angle of the guide rod 124 as needed, thereby changing the orientation of the rotating frame 123 and the grinding wheel 132. Then, the first motor 131 will drive the grinding wheel 132 to rotate and finely grind the problem area. During the grinding process, the dust suction nozzle 133 will absorb the generated dust in real time and transport it to the dust box 136 through the air duct 135. After the grinding is completed, the first electric push rod 121 can drive the grinding wheel 132 to move up and down continuously, and use the metal block at the bottom of the grinding wheel 132 to continuously knock on the weaker areas of the finished part to detect the strength of the finished part. At the same time, the inclination angle of the disc 211 can be continuously adjusted to form a vibration on the finished part to further detect the strength of the finished part.

[0076] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
