Description

Technical Field

[0001] This utility model relates to the technical field of 3D printing, and in particular to a 3D printing detection module fixing bracket and auxiliary support structure. Background Technology

[0002] In online inspection stations in industrial manufacturing (such as appearance inspection of 3C products and full dimensional inspection lines for automotive parts), to achieve visual or non-contact inspection of conveyed workpieces, inspection modules such as industrial cameras and laser displacement sensors need to be vertically mounted on the top or side of the workpiece using brackets to obtain a precise inspection perspective. Existing inspection module mounting brackets mostly adopt a structure of "L-shaped angle iron welding + screw fastening" or "customized sheet metal bending + positioning pins".

[0003] However, existing detection module mounting brackets have the following shortcomings in practical use: First, the heavy weight of traditional metal brackets limits their load-bearing capacity. To ensure structural strength, traditional brackets are usually made of thick-walled metal plates (such as Q235 steel plates) or large-sized metal profiles (such as aluminum alloy square tubes), resulting in a high overall weight. On the one hand, the excessive weight of the brackets places stringent requirements on the load-bearing capacity of the production line mounting base (such as workbenches and truss beams). If the base's load-bearing capacity is insufficient, additional reinforcement is required to prevent the brackets from sinking or vibrating, significantly increasing deployment costs. On the other hand, the bracket's own weight compresses the effective load space. When multiple components such as cameras, laser sensors, and supplementary lighting sources need to be installed simultaneously, it is easy to exceed the bracket's load-bearing limit, forcing a simplification of the detection module configuration (such as reducing the number of sensors or lowering the light source power), sacrificing detection accuracy and functional integrity. Second, the large right-angle structure of 3D printed brackets makes them prone to collapse during the printing process. While existing 3D printing-based supports have achieved lightweight design, their structural designs often include large right angles (e.g., an L-shaped structure with a 90° direct connection between a vertical support plate and a horizontal base). Because the 3D printing material (such as thermoplastic filaments in fused deposition modeling (FDM)) is in a softened state when extruded from the printhead, it requires a certain amount of time to cool and solidify to achieve sufficient hardness to maintain shape stability. In the "suspended areas" of large right-angle structures (such as the internal corners at the connection between the vertical and horizontal plates, and the overhanging portions far from the support points), the uncured material is prone to plastic deformation under gravity. Without additional support structures, the soft material will sag or collapse under its own weight, leading to loss of dimensional accuracy in that area after printing (e.g., right angles becoming obtuse angles, uneven wall thickness), and even localized fractures or delamination defects. Therefore, this application proposes a 3D printing detection module fixing bracket and auxiliary support structure. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a 3D printed inspection module fixing bracket and auxiliary support structure that reduces the overall weight of the bracket, improves the detection accuracy and functional integrity, and enhances the printing stability of the bracket.

[0005] The objective of this utility model is achieved through the following technical solution:

[0007] The main body is provided with a fixing part, a connecting part and a supporting part. One end of the fixing part is perpendicularly connected to one end of the supporting part. The two adjacent sides of the connecting part are perpendicularly connected to the fixing part and the supporting part, respectively. The fixing part is connected to the detection equipment. The supporting part is used to install the detection module. The supporting part has several through holes, and the two ends of each through hole are respectively connected to the two adjacent sides of the supporting part.

[0008] Optionally, the supporting part has a slot, the fixing part has a groove, the groove extends from the fixing part to the supporting part, and the two ends of the through hole are respectively connected to the slot and the groove.

[0009] Optionally, a sliding groove is provided on the inner side wall of the slot, and the detection module is slidably engaged with the sliding groove.

[0010] Optionally, the support portion is further provided with a plurality of through holes, each through hole penetrating the support portion, and one end of each through hole communicating with the slot.

[0011] Optionally, a limiting groove is also provided on the fixing part, and the limiting groove is used to install sensing components.

[0012] An auxiliary support structure, comprising the 3D printing inspection module fixing bracket as described in any one of the above, further comprising:

[0013] Base plate; and

[0014] A support assembly includes a circular base, a top block, a support plate, and several ring blocks. The circular base is detachably mounted on the base plate.

The 3D printing inspection module fixing bracket adopts an integrated design, with the fixing part, connecting part, and bearing part vertically connected to form a stable right-angle structure, improving support strength. The through holes, slots, and sliding grooves in the bearing part allow for neat installation of the inspection module and orderly storage of wires, preventing exposed and damaged wires. The auxiliary support structure forms a telescopic structure through ring block screw connection, and with the magnetic component adsorbing the base plate and support plate, it achieves precise height adjustment and flexible position fixation. The anti-slip part facilitates operation, and the flexible base plate and support plate are bendable, facilitating bracket removal. The limiting groove houses the sensing element, effectively limiting the movement distance and reducing the risk of impact. The overall design is adaptable to various 3D printing support needs. Thus, it improves inspection accuracy and functional integrity, as well as the stability of bracket printing. Attached Figure Description

[0028] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0029] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0032] like Figures 1 to 2As shown, in one embodiment, a 3D printing inspection module fixing bracket 2 includes a main body, on which a fixing part 21, a connecting part 22 and a supporting part 23 are provided. One end of the fixing part 21 is perpendicularly connected to one end of the supporting part 23. The two adjacent sides of the connecting part 22 are perpendicularly connected to the fixing part 21 and the supporting part 23, respectively. The fixing part 21 is connected to the inspection equipment. The supporting part 23 is used to install the inspection module. The supporting part 23 has a plurality of through holes 230, and the two ends of each through hole 230 are respectively connected to the two adjacent sides of the supporting part 23.

[0033] It should be noted that the fixing part 21, the connecting part 22, and the supporting part 23 are integrally formed structures; one end of the fixing part 21 is perpendicularly connected to one end of the supporting part 23, and one side of the fixing part 21 is parallel to one side of the supporting part 23; the two connected sides of the connecting part 22 are perpendicularly connected to the fixing part 21 and the supporting part 23 respectively, so that the fixing part 21, the connecting part 22, and the supporting part 23 together form a right-angled three-dimensional structure; since the fixing part 21 and the supporting part 23 are perpendicularly connected, when the fixing part 21 is set on the testing equipment, the supporting part 23 can extend relative to the testing equipment; and the two adjacent sides of the connecting part 22 are perpendicularly connected to the fixing part 21 and the supporting part 23 respectively, so that the supporting part 23 and the fixing part 21 have stronger stability. Furthermore, the support portion 23 is provided with a plurality of through holes 230 spaced apart, arranged in a straight line; one end of each through hole 230 communicates with the side of the support portion 23 perpendicular to the fixing portion 21, and the other end of each through hole 230 communicates with the side of the support portion 23 parallel to the fixing portion 21; when each detection module is installed on the support portion 23, the connecting wires of each detection module can pass through each through hole 230 and extend into the side of the fixing portion 21 away from the support portion 23. Since the fixing portion 21 is connected to the detection equipment, the connecting wires on each detection module can be electrically connected from the fixing portion 21 to the control unit inside the detection equipment. In this way, each detection module can be neatly installed on the support portion 23 according to actual functional requirements.

[0034] like Figures 1 to 2 As shown, in one embodiment, the supporting part 23 has a slot 231, and the fixing part 21 has a groove 210. The groove 210 extends from the fixing part 21 to the supporting part 23, and the two ends of the through hole 230 are respectively connected to the slot 231 and the groove 210.

[0035] It should be noted that a slot 231 is formed on the side of the support part 23 perpendicular to the fixing part 21. The slot 231 extends from one end of the support part 23 to the other end, and each detection module is installed in the slot 231. Several through holes are also formed on the support part 23, each through the support part 23, and one end of each through hole is connected to the slot 231. The through holes are evenly spaced, and each detection module is installed and fixed by screws passing through the through holes. A groove 210 is formed on the side of the fixing part 21 parallel to the support part 23. The two ends of the groove 210 extend to the ends of the fixing part 21 and the support part 23 that are far apart from each other, so that the groove 210 has an L-shaped structure. Furthermore, both ends of each through hole 230 are connected to the inner bottom wall of the slot 231 and the inner bottom wall of the groove 210, respectively. When the fixing part 21 is installed on the testing equipment, a cavity is formed between the groove 210 and the surface of the testing equipment, thereby allowing both ends of each through hole 230 to be connected to the inner bottom wall of the slot 231 and the cavity, respectively. In this way, after the fixing part 21 is connected and fixed to the testing equipment, the connecting wires on each testing module can be electrically connected from the cavity to the control unit inside the testing equipment, thereby avoiding the risk of being cut due to exposed connecting wires.

[0036] like Figures 1 to 2 As shown, in one embodiment, a sliding groove 2310 is provided on the inner side wall of the slot 231, and the detection module is slidably engaged with the sliding groove 2310.

[0037] It should be noted that the two inner sidewalls facing each other of the slot 231 are provided with sliding grooves 2310. The sliding grooves 2310 extend from one end of the bearing part 23 and approach the fixing part 21. After each detection module is slidably engaged with the sliding groove 2310 and slid to the actual installation position, it is fixed by screws passing through the through holes.

[0038] like Figures 1 to 2 As shown, in one embodiment, a limiting groove 211 is also provided on the fixing part 21, and the limiting groove 211 is used to install the sensing element.

[0039] It should be noted that the limiting groove 211 is located on the end face of the fixed part 21 that is away from the bearing part 23; for example, the sensing element is a limit switch; when the fixed part 21 is installed on the sliding block of the detection equipment, the detection equipment drives the fixed part 21 to move through the moving block, and then drives each detection module on each bearing part 23 to move to meet the actual detection requirements on site, so that the limit switch on the limiting groove 211 can effectively limit the sliding distance of each detection module, thereby avoiding the risk of collision of the detection module.

[0040] like Figures 3 to 5As shown, in one embodiment, an auxiliary support structure 3 further includes a base plate 30 and a support assembly. The support assembly includes a circular seat 31, a top block 32, a support plate 33, and several ring blocks 34. The circular seat 31 is detachably mounted on the base plate 30. Each ring block 34 is screwed together end to end to form a telescopic structure. The two ends of the telescopic structure are screwed to the circular seat 31 and the top block 32, respectively. The base plate 30 supports the fixing part 21, and the support plate 33 supports the connecting part 22 in an adjustable height.

[0041] It should be noted that one end of the circular seat 31 is detachably mounted on the base plate 30, and the end of the circular seat 31 away from the base plate 30 has a circular inner groove, the side wall of which is threaded; the top block 32 is a cylindrical structure, one end of which is detachably mounted on the support plate 33, and the outer side wall of the top block 32 is threaded; furthermore, the ring block 34 is a circular ring structure, and both its inner and outer side walls are threaded; for ease of description, each ring block 34 is defined as the first ring block, the second ring block, the third ring block, and the fourth ring block, respectively. The outer diameter of the ring block 34 is the same as the inner diameter of the inner groove. The inner diameter of the first ring block is the same as the outer diameter of the second ring block, the inner diameter of the second ring block is the same as the outer diameter of the third ring block, the inner diameter of the third ring block is the same as the outer diameter of the fourth ring block, and the inner diameter of the fourth ring block is the same as the outer diameter of the top block 32. This makes the ring blocks 34 connected end-to-end in a stepped manner. Specifically, the first ring block is screwed onto the circular seat 31, the second ring block is screwed onto the first ring block, the third ring block is screwed onto the second ring block, the fourth ring block is screwed onto the third ring block, and the top block 32 is screwed onto the fourth ring block. The support plate 33 is detachably mounted on the top block 32. In this way, when any one or more ring blocks 34 rotate to move away from or towards the circular seat 31, the distance between the circular seat 31 and the top block 32 can be gradually adjusted in multiple levels and segments. This allows for more precise adjustment of the height of the support plate 33 supporting the connecting part 22 to meet the support requirements of the bracket during 3D printing.

[0042] like Figure 4 As shown, in one embodiment, the support assembly further includes a plurality of magnetic elements 35, each magnetic element 35 being disposed on the circular base 31 and the top block 32, and each magnetic element 35 being used to adsorb the base plate 30 and the support plate 33.

[0043] It should be noted that circular grooves 320 are provided on the side of the circular base 31 near the base plate 30 and the side of the top block 32 near the support plate 33. For example, the magnetic component 35 is a circular magnet structure, and each magnetic component 35 is respectively set in the circular groove 320 by adhesive. In one embodiment, the magnetic component 35 is interference-fitted in the circular groove 320. Furthermore, the base plate 30 and the support plate 33 are both made of metal, so that each magnetic component 35 can drive the circular base 31 / top block 32 to be attracted to the base plate 30 / support plate 33, thereby allowing the circular base 31 / top block 32 to be detachably removed from the base plate 30 / support plate 33, and allowing the circular base 31 to be attracted to any position on the base plate 30 to meet the support requirements of different brackets during printing. Furthermore, since different supports require different sizes of support positions, operators can remove the support plate 33 from the top block 32 and replace it with a suitable support plate 33. For example, the support plate 33 can be square, rectangular, or strip-shaped. Moreover, the support plate 33 can also be a support structure with curved surfaces, such as hemispherical, S-shaped, or other irregular shapes. In this way, the auxiliary support structure 3 can adapt to various support requirements in 3D printing.

[0044] like Figures 3 to 5 As shown, in one embodiment, an anti-slip portion 340 is provided on the ring block 34, and the anti-slip portion 340 is provided along the circumference of the ring block 34.

[0045] It should be noted that each annular block 34, circular seat 31, and top block 32 is provided with an annular anti-slip part 340. The outer diameter of each anti-slip part 340 is larger than the outer diameter of each annular block 34, circular seat 31, and top block 32, so that each anti-slip part 340 protrudes relative to the outer wall of each annular block 34, circular seat 31, and top block 32. In this way, the operator can rotate each annular block 34 / circular seat 31 / top block 32 by using the anti-slip part 340, thereby adjusting the interval distance between the circular seat 31 and the top block 32.

[0046] like Figure 3 As shown, in one embodiment, both the base plate 30 and the support plate 33 are flexible.

[0047] It should be noted that the base plate 30 and support plate 33 are made of metal, possessing the characteristic of being able to bend to a certain extent without deforming or breaking. Because the 3D printing material needs to be heated to soften it before being extruded from the print head, and the freshly extruded material is in a softened state, it easily adheres to the base plate 30 / support plate 33, requiring cooling and solidification to maintain its shape. This means that the hardened support structure cannot be directly peeled off from the base plate 30 / support plate 33. Therefore, by slightly bending the base plate 30 / support plate 33, the hardened support structure can be easily peeled off from it.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
