Description

Technical Field

[0001] This utility model belongs to the technical field of adhesive coating devices, and in particular relates to an online detection type 3D adhesive coating mechanism. Background Technology

[0002] A 3D coating system is a device that automatically and precisely applies fluid materials such as sealants, adhesives, and lubricants to the surface of a three-dimensional object along a pre-set, often irregular, path. In fields such as automotive manufacturing, electronic packaging, and aerospace, this type of system is crucial for achieving precise coating on complex curved surfaces. Existing 3D coating systems have significant limitations, primarily in the lack or inadequacy of detection capabilities. Most traditional equipment can only complete the coating operation and cannot monitor the coating quality in real time, resulting in difficulties in promptly detecting defects such as uneven coating thickness, glue breaks, or glue overflow.

[0003] While some improved equipment is equipped with detection devices, the use of fixed detection modules presents serious compatibility issues. When the adhesive application mechanism moves along irregular paths in three-dimensional space, the fixed detection device cannot maintain the optimal detection angle and distance, resulting in distorted adhesive application quality data. This structural defect prevents the detection results from accurately reflecting the adhesive application status, ultimately affecting the effectiveness of product quality control. Furthermore, the drive systems of existing equipment often lack precise synchronization control mechanisms, making it difficult for the detection elements and the adhesive application process to coordinate their movements, further reducing detection accuracy.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this invention is to provide an online detection 3D coating mechanism, which has the advantages of real-time monitoring of coating quality, maintaining the optimal detection angle, and improving detection accuracy, so as to solve the problem of missing or insufficient detection functions of traditional equipment.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: an online detection type 3D glue coating mechanism, including a top plate, a glue coating tube and a detection module. The glue coating tube is installed on the top plate and located at the center of the top plate. The detection module includes a camera and a laser light. The camera and laser light are installed on the top plate in a way that allows them to be driven to rotate synchronously around the central axis of the glue coating tube.

[0007] Furthermore, it also includes a rotating substrate, which is mounted on the bottom surface of the top plate in a manner that allows it to rotate around the central axis of the dispensing tube. The rotating substrate is coaxial with the top plate, the dispensing tube passes through the rotating substrate, and the camera and laser are connected to the top plate through the rotating substrate.

[0008] Furthermore, it also includes a drive mechanism, which includes a drive source, a drive plate, and a connecting rod. The drive plate is sleeved on the glue-applying tube and located between the top plate and the rotating base plate. The drive plate is connected to the rotating base plate through the connecting rod. The drive source is fixedly installed on the top plate and connected to the drive plate. The drive plate and the rotating base plate are coaxially arranged. The drive plate can be driven by the drive source to rotate around the central axis of the glue-applying tube. The rotating base plate rotates accordingly to drive the camera and laser to rotate synchronously.

[0009] Furthermore, the drive mechanism also includes a transmission gear pair, which includes at least a driving gear and a driven gear. The driving gear is mounted on the drive source to output power, and the driven gear is fixedly mounted on the drive plate to receive the power output from the drive source and drive the drive plate to rotate.

[0010] Furthermore, it also includes a protective shell and a connector. The protective shell is installed on the top surface of the rotating base plate and is vertically oriented, with the top periphery of the protective shell not exceeding the top plate. The connector is installed on the top surface of the top plate, and the top plate is installed at a set position via the connector.

[0011] Furthermore, it also includes a mounting bracket, which is installed on the top surface of the top plate, and the adhesive application tube is installed on the top plate through the mounting bracket.

[0012] Furthermore, the camera and laser are arranged sequentially from the inside to the outside along the radial direction of the rotating base plate. The camera is vertically mounted on the rotating base plate with the lens facing downwards, and the laser is mounted on the rotating base plate with the light irradiation direction tilted towards the camera.

[0013] The beneficial effects of this technical solution are as follows:

[0014] This invention provides an online detection-type 3D adhesive coating mechanism. By setting up a detection module that can rotate synchronously, the shooting angle of the detection module can be adjusted in real time, thereby realizing the function of real-time monitoring of adhesive coating quality and maintaining the optimal detection angle and distance during the adhesive coating process. It solves the problem of missing or insufficient detection functions in traditional equipment and has the advantages of improving detection accuracy and ensuring adhesive coating quality.

[0020] The following detailed description illustrates the specific implementation method:

[0021] The reference numerals in the accompanying drawings include: top plate 1, glue tube 2, connector 3, protective shell 4, drive source 5, mounting bracket 6, rotating base plate 7, laser light 8, camera 9, connecting rod 10, drive plate 11, driving gear 12, driven gear 13.

[0022] 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.

[0023] The basic implementation examples are as follows: Figure 1-5The diagram illustrates an online inspection-type 3D adhesive coating mechanism, comprising a top plate 1, an adhesive coating tube 2, and an inspection module. The adhesive coating tube 2 is mounted on the top plate 1 and located at its center. The inspection module includes a camera 9 and a laser 8, which are mounted on the top plate 1 in a drivable manner to rotate synchronously around the central axis of the adhesive coating tube 2. Specifically, the top plate 1, as a supporting structure, can be made of metal sheet or high-strength composite material, and its shape can be circular, square, or other polygonal. The adhesive coating tube 2 is used to transport fluid materials, and its material can be corrosion-resistant stainless steel or engineering plastic. In the inspection module, the camera 9 can be an industrial CCD or CMOS sensor, preferably with a resolution of no less than 2 megapixels; the laser 8 can be a red or blue laser diode. The synchronous rotation function can be driven by a stepper motor or a servo motor. By setting the inspection module as a rotatable structure, the problem of fixed inspection devices being unable to adapt to irregular adhesive coating paths is solved. The synchronous rotation of the camera 9 and laser 8 around the adhesive coating tube 2 enables real-time acquisition of image data corresponding to the adhesive coating quality at any angle (especially the optimal inspection angle). Compared with existing technologies, the rotational detection method eliminates blind spots and improves detection coverage and accuracy. Specifically, the laser lamp 8 provides a structured light source, and the image data acquired by the camera 9 can be used for 3D reconstruction and defect identification. The rotational motion ensures comprehensive monitoring of complex adhesive application trajectories. As a preferred implementation, the synchronous rotation function of the detection module can adopt closed-loop control to precisely match the movement trajectory of the adhesive application head. This achieves online detection of adhesive application quality and synchronization of the adhesive application process, effectively ensuring the consistency of the final product quality. Specifically, the rotating base plate 7 can be made of aluminum alloy or engineering plastic. The coaxial rotational connection between the rotating base plate 7 and the top plate 1 can be achieved through an arc-shaped slide groove and a lifting rod. That is, symmetrical arc-shaped slide grooves are opened on the top plate 1, and then the rotating base plate 7 is lifted into the slide groove by the lifting rod, thereby achieving a sliding connection. Of course, the coaxial rotational connection between the rotating base plate 7 and the top plate 1 can also be achieved through bearings or other methods. This is a conventional technical method used here and will not be elaborated further.

[0024] In this embodiment, a rotating substrate 7 is also included. The rotating substrate 7 is mounted on the bottom surface of the top plate 1 in a drivable manner around the central axis of the coating tube 2, and the rotating substrate 7 is coaxially arranged with the top plate 1. The coating tube 2 passes through the rotating substrate 7, and the camera 9 and laser lamp 8 are connected to the top plate 1 through the rotating substrate 7. Thus, the addition of the coaxially rotating rotating substrate 7 changes the relative positional relationship between the detection module and the coating tube 2 from a fixed type to a synchronous rotation type. Specifically, when the coating tube 2 moves along a three-dimensional path, the rotating substrate 7 drives the camera 9 and laser lamp 8 to rotate synchronously, ensuring that the detection light always perpendicularly illuminates the cross-section of the adhesive strip. This solves the problem that a fixed detection device cannot adapt to three-dimensional trajectory detection, realizing real-time online monitoring of coating quality; this structure ensures that the detection device is always aligned with the normal direction of the coating path, significantly improving detection accuracy and reliability.

[0025] This embodiment also includes a driving mechanism, which comprises a driving source 5, a driving plate 11, and a connecting rod 10. The driving plate 11 is sleeved on the glue-applying tube 2 and located between the top plate 1 and the rotating base plate 7. The driving plate 11 is connected to the rotating base plate 7 via the connecting rod 10. The driving source 5 is fixedly installed on the top plate 1 and connected to the driving plate 11. The driving plate 11 and the rotating base plate 7 are coaxially arranged. The driving plate 11 can be driven by the driving source 5 to rotate around the central axis of the glue-applying tube 2. The rotating base plate 7 rotates accordingly to drive the camera 9 and the laser lamp 8 to rotate synchronously. Specifically, the driving source 5 can be a servo motor or a stepper motor; the connecting rod 10 between the driving plate 11 and the rotating base plate 7 can be a rigid connector 3, such as a metal rod or a high-strength plastic rod, to ensure the stability of power transmission. Multiple driving rods are provided, and the multiple driving rods are arranged in a ring array to improve connection stability. As a preferred embodiment, a bearing can be provided between the driving plate 11 and the glue-applying tube 2 to reduce frictional resistance. The connection method between the driving source 5 and the driving plate 11 can be direct drive or indirect drive through belts, gear pairs, or chains. Thus, this technical solution achieves synchronous rotation of camera 9 and laser 8 through a drive mechanism, solving the problem in existing technologies where fixed detection devices cannot adapt to irregular adhesive application paths. The drive source 5 drives the drive plate 11 to rotate, and the drive plate 11 transmits power to the rotating base plate 7 via connecting rod 10, enabling camera 9 and laser 8 to perform real-time detection following the adhesive application path. This design ensures the detection device is always aligned with the adhesive application position, improving the accuracy and reliability of the detection. Compared to existing technologies, this solution has a compact structure, stable power transmission, and enables synchronous movement between the detection device and the adhesive application mechanism.

[0026] In this embodiment, the drive mechanism further includes a transmission gear pair, which includes at least a driving gear 12 and a driven gear 13. The driving gear 12 is mounted on the drive source 5 to output power, and the driven gear 13 is fixedly mounted on the drive plate 11 to receive the power output from the drive source 5 and drive the drive plate 11 to rotate. As a key component for power transmission, the transmission gear pair has the driving gear 12 directly connected to the output shaft of the drive source 5, and the driven gear 13 fixedly connected to the drive plate 11. By adding the transmission gear pair, reliable power transmission between the drive source 5 and the drive plate 11 is achieved. Compared with the direct drive method, gear transmission has higher transmission efficiency and more precise speed control, ensuring the smooth rotation of the camera 9 and the laser lamp 8. At the same time, the gear pair has a compact structure, which is convenient for arrangement in a limited space and does not affect the overall compactness of the mechanism. This design solves the problems of unstable power transmission and inaccurate speed control that may exist in the direct drive method, providing more reliable hardware support for online detection.

[0027] In this embodiment, a protective shell 4 and a connector 3 are also included. The protective shell 4 is installed on the top surface of the rotating base plate 7 and is vertically oriented, with the top periphery of the protective shell 4 not exceeding the top plate 1. The connector 3 is installed on the top surface of the top plate 1, and the top plate 1 is installed in a set position via the connector 3. Specifically, the protective shell 4 can be made of metal or engineering plastic, and its shape is preferably an annular shell. The bottom of the protective shell 4 can be fixedly connected to the rotating base plate 7 by bolts. The connector 3 can be in the form of a flange, a connecting rod, or a mounting bracket 6, etc. Thus, by adding the protective shell 4, external dust and splashes are effectively blocked from entering the movement gap between the rotating base plate 7 and the drive mechanism, avoiding the accumulation of impurities that cause rotational jamming; at the same time, the height limitation of the protective shell 4 ensures that the overall structure is compact and will not interfere with the working space of the glue application tube 2. The setting of the connector 3 allows the top plate 1 to be stably fixed on the robotic arm or frame, eliminating vibration and displacement during glue application. In specific implementation, a wear-resistant bushing can be added to the inner wall of the protective shell 4 to extend its service life, and the surface of the connector 3 can be treated with rust prevention to adapt to different working environments. As a result, while maintaining the original detection accuracy, the reliability of equipment operation and ease of installation have been significantly improved.

[0028] In this embodiment, a mounting bracket 6 is also included. The mounting bracket 6 is installed on the top surface of the top plate 1, and the adhesive application tube 2 is installed on the top plate 1 through the mounting bracket 6. The mounting bracket 6 can be made of metal sheet by stamping or machining, and its structural form includes, but is not limited to, L-shaped bracket, U-shaped bracket, or ring bracket. As a preferred embodiment, the mounting bracket 6 is detachably connected to the top plate 1 by bolt fasteners. The adhesive application tube 2 and the mounting bracket 6 can be fixed by flange connection, clamp fastening, or interference fit. Thus, by adding a dedicated mounting bracket 6, the adhesive application tube 2 can achieve stable and reliable positioning and installation. Specifically, the mounting bracket 6 effectively transmits the axial load and radial torque of the adhesive application tube 2 to the top plate 1, avoiding the local stress concentration problem that may occur if the adhesive application tube 2 is directly fixed to the top plate 1. Furthermore, the modular installation structure facilitates the quick disassembly and maintenance of the adhesive application tube 2, while ensuring that the central axis of the adhesive application tube 2 maintains strict coaxiality requirements with the rotating base plate 7, which plays an important role in ensuring the synchronous rotation detection accuracy of the camera 9 and the laser lamp 8. Compared to the solution of directly fixing the glue applicator tube 2 to the top plate 1, this structure significantly improves the rigidity and positioning accuracy of the overall mechanism.

[0029] In this embodiment, the camera 9 and the laser lamp 8 are arranged sequentially from the inside to the outside along the radial direction of the rotating substrate 7. The camera 9 is vertically mounted on the rotating substrate 7 with the lens facing downwards, and the laser lamp 8 is mounted on the rotating substrate 7 with the light irradiation direction tilted towards the camera 9. Specifically, the radial arrangement of the camera 9 and the laser lamp 8 ensures that the light from the laser lamp 8 can cover the adhesive coating area within the field of view of the camera 9. The vertical mounting of the camera 9 ensures that the imaging plane is parallel to the adhesive coating surface, and the tilted mounting of the laser lamp 8 projects the light onto the adhesive coating surface at a specific angle. As a preferred embodiment, the tilt angle of the laser lamp 8 can be set to 30-60 degrees, which can effectively form laser stripes with suitable contrast. In another embodiment, the laser lamp 8 can use a universal adjustment bracket to achieve multi-dimensional adjustment of the irradiation angle. The camera 9 can use an industrial-grade CCD or CMOS sensor, and the distance between its mounting position and the central axis of the adhesive coating tube 2 is preferably 1.5-2 times the diameter of the adhesive coating tube 2. This distance range can ensure a complete imaging field of view and avoid adhesive splashing that contaminates the lens. Therefore, this technical solution solves the problem of blind spots in adhesive coating trajectory detection caused by the limited field of view in fixed detection devices by optimizing the spatial layout and installation method of the optical detection components. The vertically mounted camera 9, combined with the three-dimensional light field formed by the tilted laser illumination, can accurately capture the contour features of the three-dimensional adhesive coating trajectory; the radial arrangement design enables spatial matching between the detection area and the adhesive coating operation area, achieving real-time closed-loop detection of adhesive coating quality. Compared with existing fixed detection devices, this solution significantly improves the online detection accuracy of adhesive coating on irregular three-dimensional paths, and its compact structure does not affect the motion freedom of the adhesive coating mechanism.
