Description

Technical Field

[0001] This invention belongs to the field of additive manufacturing, and more specifically, relates to a testing device for additive manufacturing. Background Technology

[0002] Additive manufacturing, commonly known as "3D printing," is a technology that creates three-dimensional objects by layering materials. It is completely opposite to the "subtraction" mode of traditional subtractive manufacturing (such as cutting and grinding). Its core principle is to discretize a digital model (such as a CAD file) into multiple layers of two-dimensional slices, and then build up materials point by point, line by line, and surface by surface to finally form a solid part. As an innovative manufacturing technology, it can ingeniously transform digital designs into three-dimensional solid parts by its unique layer-by-layer material accumulation method. However, when existing inspection devices inspect finished workpieces by infrared scanning, the inspection time is long and the number of inspections is large. The defects detected are not consistent, resulting in low inspection efficiency. It is also affected by the number of scans and whether the scan is comprehensive, which leads to inaccurate inspection results.

[0003] Chinese patent CN222719462U discloses a laser inspection device for additive manufacturing. This device uses a motor to rotate a support disk carrying the finished product, causing the finished product to rotate and allowing the inspection probe to perform a more comprehensive inspection. In addition, through the action of a drive gear and a connecting gear, the connecting gear ring rotates, driving the protrusion to move, allowing the contact post to move up and down with the inspection probe. While performing circumferential scanning, it can also perform oblique scanning simultaneously, thus making the inspection of the finished workpiece more comprehensive and complete, and improving the inspection efficiency. However, this device requires the finished workpiece to be placed on the support disk during inspection. When inspecting a large number of finished workpieces, it takes a lot of time, thus reducing the inspection efficiency of finished workpieces.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a testing device for additive manufacturing, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0011] A connecting plate is fixedly mounted on the belt of the belt drive mechanism. A drive rod is fixedly mounted on the connecting plate. One end of the drive rod away from the connecting plate passes through the mounting plate and is fixedly connected to the sliding plate. A drive groove is provided through the mounting plate to allow the drive rod to move laterally.

[0012] Optionally, a second slider is fixedly mounted on the sliding plate, and the mounting plate is provided with a second groove for the second slider to slide.

[0013] Optionally, two first sliders are fixedly mounted on the mounting plate, and the fixing frame is provided with a first groove for the first sliders to slide.

[0035] The invention will now be described in further detail with reference to the accompanying drawings.

[0036] Please see Figure 1-8 As shown, this embodiment provides an additive manufacturing testing device, including a conveyor belt mechanism 1, a fixed frame 2 and a mounting plate 4 fixedly mounted on its top, which are slidably mounted on the fixed frame 2. A sliding plate 7 is slidably mounted on the mounting plate 4, and a main testing device 6 is fixedly mounted on the sliding plate 7. The fixed frame 2 is provided with a driving assembly 8 that drives the mounting plate 4 to slide longitudinally along the fixed frame 2 and drives the sliding plate 7 to slide laterally along the mounting plate 4.

[0037] Specifically, in this embodiment, a position sensor 3 is installed on the transmission belt mechanism near the fixed frame 2 to stop the operation of the transmission belt mechanism when the workpiece moves to the bottom of the fixed frame 2. Both the position sensor 3 and the transmission belt mechanism 1 are controlled by an external control device, and their wiring and signal connection relationships are existing technologies. When inspecting the finished product, the external control device controls the start of the transmission belt mechanism 1 to transport the additively manufactured finished product to the inspection area below the fixed frame 2. The external control device starts the main inspection device 6, and at the same time, the drive assembly 8 on the fixed frame 2 starts, driving the mounting plate 4 to slide longitudinally along the fixed frame 2. After the mounting plate 4 moves to the designated position, the sliding plate 7 is driven to slide laterally along the mounting plate 4. After the inspection is completed, the transmission belt sends the finished product out of the inspection area and transports the next workpiece to be inspected. The inspection process is repeated cyclically. The overall structure and operation steps are simple and efficient. The drive assembly 8 enables the main inspection device 6 to fully cover the finished product for inspection, improving the inspection area and inspection quality, and improving the inspection efficiency of the finished product.

[0038] It should be noted that in this embodiment, the conveyor belt mechanism 1 can be a belt drive mechanism, roller conveyor mechanism, etc. in the prior art, and its working principle and structure are all prior art.

[0039] In this embodiment, as Figures 1 to 7 As shown, the drive assembly 8 includes a belt drive mechanism 82, which is mounted on a fixed frame 2 relative to the mounting plate 4. A motor 81 for driving the belt drive mechanism 82 to rotate is fixedly mounted on the fixed frame 2. A connecting plate 84 is fixedly mounted on the belt of the belt drive mechanism 82. A drive rod is fixedly mounted on the connecting plate 84. One end of the drive rod away from the connecting plate 84 passes through the mounting plate 4 and is fixedly connected to the sliding plate 7. A drive groove 85 for the drive rod to move laterally is provided through the mounting plate 4. A second slider 12 is fixedly mounted on the sliding plate 7. A second sliding groove 13 for the second slider 12 to slide is provided on the mounting plate 4. Two first sliders 5 are fixedly mounted on the mounting plate 4. A first sliding groove 10 for the first sliders 5 to slide is provided on the fixed frame 2. The first sliders 5 have an L-shaped structure. Specifically, in this embodiment, the structure, installation method, and connection position of the belt drive mechanism 82 and the motor 81 are all existing technologies. The longitudinal sliding of the mounting plate 4 and the lateral sliding of the sliding plate 7 are realized simultaneously by a motor 81 and a belt drive mechanism 82, which simplifies the drive structure and reduces equipment cost and energy consumption.

[0040] In this embodiment, as Figures 3 to 6 As shown, a plurality of pulleys 11 are rotatably connected to the first slider 5. The pulleys 11 are rolled within the first slide groove 10. Specifically, the pulleys 11 roll within the first slide groove 10, converting sliding friction into rolling friction, reducing the friction between the first slider 5 and the first slide groove 10, reducing the load on the drive assembly 8, improving the smoothness and efficiency of the sliding of the mounting plate 4, and also reducing the wear of components and extending the service life of the equipment.

[0041] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 8As shown, an auxiliary detection component 9 is fixedly mounted on the first slider 5. The auxiliary detection component 9 includes a fixed rod 91 fixedly connected to the first slider 5, a mounting frame 93 fixedly mounted on the fixed rod 91, and a secondary detection device 92 disposed within the mounting frame 93. A rotating frame 14 is rotatably connected to the mounting frame 93 via a rotating shaft 15. The secondary detection device 92 is fixedly mounted within the rotating frame 14. The mounting frame 93 is provided with a worm gear mechanism 16 for driving the rotating shaft 15 to rotate. Specifically, the auxiliary detection component 9 is mounted on the first slider 5 via the fixed rod 91 and moves with the movement of the first slider 5. The secondary detection device 92 is mounted within the mounting frame. Within 93, additional inspections can be performed on the finished product, increasing the inspection dimensions and functions. Simultaneous multi-directional inspection of the finished product improves the comprehensiveness and accuracy of the inspection. Secondly, the worm gear mechanism 16 enables angle adjustment of the auxiliary inspection device 92, allowing for adjustments to the inspection angle according to different inspection needs and the shape of the finished product, thus improving the flexibility and adaptability of the inspection. It should be noted that in this embodiment, the main inspection device 6 is positioned directly opposite the finished product, inspecting the top of the finished product, while the auxiliary inspection device 92 inspects the sides of the finished product, thereby achieving large-area inspection of the finished product and further improving the inspection effect and accuracy.

[0042] Furthermore, in this embodiment, the main detection device 6 and the auxiliary detection device 92 can be high-speed cameras, laser scanners (used to detect finished product dimensional deviations, surface morphology and structural defects, etc.) or infrared sensors (which generate temperature distribution images by capturing infrared radiation energy on the surface of an object, or use the principle of infrared thermal imaging to penetrate the material surface and detect internal defects such as pores and delamination), etc. In this embodiment, both the main detection device 6 and the auxiliary detection device 92 are high-speed cameras, which are used to detect visible defects such as surface cracks and excessive surface roughness of finished products. In other embodiments, they can be adjusted according to the actual situation, and no constraints are imposed here. At the same time, the signal connection method and wiring installation method between the detection device and external computers and other devices are all existing technologies.

[0043] Working principle:

[0044] First, the worm gear mechanism 16 drives the rotating shaft 15 to rotate, adjusting the angle of the auxiliary inspection device 92. Then, the additively manufactured finished product is placed at the beginning of the transmission belt and transported to the inspection area below the fixed frame 2 via the conveyor belt mechanism 1. The main inspection device 6 and the auxiliary inspection device 92 are started, and the motor 81 is controlled by an external control device to drive the belt drive mechanism 82 to rotate, causing the connecting plate 84 to move. The connecting plate 84 drives the drive shaft 83 to move. Since the belt of the belt drive mechanism 82 is circular, the drive rod also moves in a circular trajectory. The rotation of the belt drive mechanism 82 also causes the mounting plate 4 to slide longitudinally along the fixed frame 2. While the first slider 5 moves, the auxiliary inspection component 9 moves synchronously with the first slider 5. Next, when the drive rod moves to the belt drive mechanism 82... At the pulley, the drive rod on the connecting plate 84 slides in the drive groove 85, enabling the sliding plate 7 to slide laterally along the mounting plate 4. After the drive rod rotates to the opposite end along one end of the pulley, the mounting plate 4 moves back as the belt drive mechanism 82 continues to rotate. During this process, the main inspection device 6 and the auxiliary inspection device 92 inspect the finished product and obtain relevant data. The data obtained by the main inspection device 6 and the auxiliary inspection device 92 are integrated and analyzed, and sent to external computers and other equipment to comprehensively evaluate the quality of the finished product. The belt drive mechanism 82 drives the main inspection device 6 to move along a circular trajectory, thereby realizing the inspection area and inspection quality of the finished product. After the inspection is completed, the conveyor belt continues to transport the finished product and repeats the above inspection process to achieve efficient inspection of continuously produced additive manufacturing products.
