Description

Technical Field

[0001] This invention relates to the field of automated packaging technology, and in particular to a foam bonding device based on machine vision. Background Technology

[0002] As smart electronic products become thinner, lighter, and more precise, the application of functional materials like foam in assembly is becoming increasingly widespread, especially in the manufacturing of smart pens. To reduce gaps and movement after component assembly and to provide shock absorption and cushioning, preventing loosening and vibration after the pen refill is installed, foam needs to be precisely adhered to specific areas of the pen body. In existing technologies, the foam adhesion process is mostly completed manually.

[0003] However, manual pasting has many drawbacks: on the one hand, the inner bottom of smart pen products is quite deep, and the space for foam pasting is small, making manual operation difficult and inefficient; on the other hand, manual pasting is prone to uneven pasting and other deviations, which directly affect product quality and thus interfere with the installation and use of subsequent related products. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings mentioned above by providing a machine vision-based foam bonding device that enables precise and efficient foam bonding and improves product assembly consistency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a foam bonding device based on machine vision, comprising: The enclosure assembly includes a cabinet body with an integrated control module inside and a protective cover disposed on the top of the cabinet body; A rotating assembly, comprising a positioning component for clamping the pen body and a rotating drive component disposed on the cabinet body and driving the positioning component to rotate; The fitting motion assembly includes a suction nozzle component for adsorbing foam, a horizontal moving component for driving the suction nozzle component to move horizontally, and a lifting component disposed on the cabinet body and driving the horizontal moving component to move closer to or further away from the positioning component. A visual component is installed on the cabinet and used to photograph and recognize the pen body on the positioning component.

[0006] Furthermore, the positioning component includes a card holder disposed at the driving end of the rotary drive component. The card holder has a positioning pin corresponding to the hole in the pen body. The card holder is rotatably disposed on a flip cover for pressing the pen body down onto the card holder via a torsion spring, and a locking hook for locking the flip cover after it is snapped shut. The flip cover and the locking hook are disposed opposite to each other on the card holder.

[0007] Furthermore, the suction nozzle component includes a vertical slide rail and a pressure sensor disposed at the drive end of the horizontal moving component. A slider that can slide up and down and is located on top of the pressure sensor is disposed on the side of the vertical slide rail near the pressure sensor. A pressure-holding spring is disposed between the slider and the pressure sensor. A vacuum suction nozzle for adsorbing foam is disposed on the top of the slider.

[0008] Furthermore, the vacuum nozzle is provided with a positioning groove for positioning the foam, and the nozzle component also includes a linear lifting cylinder provided at the drive end of the horizontal moving component. The top of the linear lifting cylinder is provided with a mounting seat that moves up and down driven by the linear lifting cylinder, and the mounting seat is provided with a pin for positioning the release paper of the foam.

[0009] Furthermore, the horizontal moving component consists of an XY-axis bidirectional electric slide that drives the suction nozzle component to move horizontally linearly and an electric turntable that drives the suction nozzle component to rotate horizontally.

[0010] Furthermore, the vision component includes a Z-axis linear module mounted on the cabinet body and a CCD camera that is driven to move up and down by the Z-axis linear module, with the CCD camera located above the positioning component.

[0011] Furthermore, the visual component also includes a ring light that is fitted outside the CCD camera lens and coaxially arranged with the CCD camera, the ring light being used to provide supplemental lighting to the shooting area.

[0012] The beneficial effects of this invention are reflected in: This invention employs a positioning component in conjunction with visual inspection, increasing the positioning space and improving the accuracy of pen body positioning, while also adapting to the positioning requirements of pen bodies of different sizes. Through the coordinated rotation and bonding of the rotating component and the bonding motion component, a highly efficient rotary motion system is formed, significantly improving foam bonding efficiency. The movement trajectory of each component is precisely controlled by the control module, ensuring bonding consistency across multiple batches of products. Full-process visual monitoring combined with feedback adjustment effectively avoids foam bonding deviations, improves product assembly quality, and solves the technical problems of difficult manual operation, low efficiency, and inaccurate bonding.

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-8 The present invention discloses a foam bonding device based on machine vision, including a housing assembly 1, a rotating assembly 2, a bonding motion assembly 3 and a vision assembly 4; The enclosure component 1 includes a cabinet with an integrated control module inside and a protective cover on the top of the cabinet, which provides installation support and protection for each component. The control module is electrically connected to the rotating component 2, the contact motion component 3, and the vision component 4 respectively, and is used to coordinate and control the coordinated action of each component. The rotating component 2 includes a positioning component 21 for clamping the pen body and a rotating drive component 22 mounted on the cabinet body and driving the positioning component 21 to rotate, forming a rotating motion system; the rotating drive component 22 receives instructions from the control module to drive the positioning component 21 to rotate the pen body along a preset trajectory, which, together with the bonding motion component 3, achieves high-efficiency foam bonding, and the fixed positioning trajectory ensures product consistency. The bonding motion assembly 3 includes a suction nozzle 31 for adsorbing foam, a horizontal moving part 32 for driving the suction nozzle 31 to move horizontally, and a lifting part 33 mounted on the cabinet and driving the horizontal moving part 32 to move closer to or further away from the positioning part 21. The horizontal moving part 32 and the lifting part 33 receive instructions from the control module and work together to drive the suction nozzle 31 to a preset bonding position, completing the foam bonding during the rotation of the pen body driven by the rotating part 2. The vision component 4 is set on the cabinet and is used to take pictures and identify the pen body on the positioning component 21. The vision component 4 transmits the captured image data to the control module, which analyzes the pen body status and adjusts the rotation component 2 and the fitting motion component 3 to compensate and adjust, so as to ensure the product fitting status.

[0017] This invention achieves automated assembly of smart pen foam, which has the following advantages compared to the traditional manual pasting method: The use of positioning component 21 in conjunction with visual inspection increases the positioning space, improves the accuracy of pen body positioning, and can adapt to the positioning requirements of pen bodies of different specifications. Through the coordinated rotation and bonding of rotating component 2 and bonding motion component 3, a highly efficient rotary motion system is formed, which greatly improves the foam bonding efficiency. The motion trajectory of each component is precisely controlled by the control module, ensuring the bonding consistency of multiple batches of products. Full-process visual monitoring and feedback adjustment effectively avoid foam bonding deviation, improve product assembly quality, and solve the technical problems of difficult manual operation, low efficiency, and inaccurate bonding.

[0018] In one embodiment, the positioning component 21 includes a card holder 211 disposed at the driving end of the rotary drive component 22. The card holder 211 has a positioning pin corresponding to the hole in the pen body. The card holder 211 is rotatably provided with a flip cover 212 for pressing the pen body down onto the card holder 211 via a torsion spring, and a locking hook 213 for locking the flip cover 212 after it is fastened. The flip cover 212 and the locking hook 213 are disposed opposite to each other on the card holder 211.

[0019] This design solves the problems of limited operating space, inaccurate positioning, and easy displacement of the pen body during the traditional manual positioning process. It achieves stable and precise positioning of the pen body, while improving the convenience and versatility of the positioning operation. Specifically: the positioning pin on the holder 211 cooperates with the hole in the pen body to quickly achieve preliminary and accurate positioning of the pen body, ensuring a unified positioning benchmark; the flip cover 212 driven by a torsion spring presses down and fixes the pen body, preventing it from shaking or floating during the fitting process; the locking hook 213 locks the flip cover 212 after it is snapped on, further strengthening the fixing effect and ensuring the stability of the pen body's posture during the rotation and fitting process.

[0020] In practice, the pressing surface of the flip cover 212 can be equipped with an elastic buffer pad, which increases the friction with the pen body and improves the fixing stability, and avoids scratching damage to the pen body surface during the pressing process. The bearing surface of the card holder 211 can be provided with an arc-shaped groove, the curvature of which matches the outer contour of the pen body, further increasing the contact area between the pen body and the card holder 211 and improving the positioning stability. At the same time, anti-slip textures can be provided in the groove to reduce the circumferential displacement of the pen body during the bonding process.

[0021] In one embodiment, the suction nozzle component 31 includes a vertical slide rail 311 and a pressure sensor 312 disposed at the drive end of the horizontal moving component 32. A slider 313 that can slide up and down and is located on top of the pressure sensor 312 is disposed on the side of the vertical slide rail 311 near the pressure sensor 312. A pressure-holding spring 314 is disposed between the slider 313 and the pressure sensor 312. A vacuum suction nozzle 315 for adsorbing foam is disposed on the top of the slider 313.

[0022] This design enables stable adsorption and precise bonding of the foam, while avoiding damage or insecure bonding caused by improper pressure during the bonding process. Specifically: the vacuum nozzle 315 adsorbs and fixes the foam, ensuring it does not fall off or shift during transport and bonding; the vertical slide rail 311 and slider 313 provide guidance for the vacuum nozzle 315 to slide up and down, ensuring vertical accuracy during foam bonding; the combination of pressure sensor 312 and pressure-holding spring 314 can detect the pressure value during foam bonding in real time. When the pressure exceeds a preset threshold, slider 313 compresses pressure-holding spring 314 and triggers a feedback signal from pressure sensor 312, allowing the control module to adjust the bonding pressure and prevent damage to the foam; pressure-holding spring 314 also has a buffering function, compensating for minor height deviations during bonding, ensuring full bonding between the foam and the pen body surface, and improving bonding quality.

[0023] It should be noted that the vacuum nozzle 315 adopts a detachable structure and connects to the vacuum pipeline through a quick connector, making it easy to replace the nozzle with the corresponding specification according to the size and shape of the foam, thus improving the equipment's versatility.

[0024] In one embodiment, the vacuum nozzle 315 is provided with a positioning groove for positioning the foam, and the nozzle component 31 also includes a linear lifting cylinder 316 provided at the driving end of the horizontal moving component 32. The top of the linear lifting cylinder 316 is provided with a mounting base 317 that moves up and down driven by the linear lifting cylinder 316, and the mounting base 317 is provided with a pin 318 for positioning the release paper of the foam.

[0025] This design further enhances the positioning accuracy of the foam adsorption process, ensuring the quality of subsequent bonding. Specifically: the positioning groove on the vacuum nozzle can circumferentially limit the foam, ensuring accurate posture during foam adsorption and preventing adsorption deviation; the linear lifting cylinder 316 drives the mounting base 317 and pin 318 to rise, allowing the pin 318 to be inserted into the holes of the foam release paper, achieving precise positioning and preventing foam deviation during rotational bonding; the two pins 318 form a two-point positioning, improving positioning stability.

[0026] In one embodiment, the horizontal moving component 32 consists of an XY-axis bidirectional electric slide that drives the suction nozzle component 31 to move horizontally linearly and an electric turntable that drives the suction nozzle component 31 to rotate horizontally.

[0027] This design enables precise multi-dimensional movement of the suction nozzle component 31 in the horizontal direction. Combined with the rotational motion of the rotating component 2, it achieves efficient and precise foam bonding, while also improving the device's adaptability to different bonding trajectories. Specifically: the XY-axis bidirectional electric slide can drive the suction nozzle component 31 to move linearly along the horizontal X and Y axes, allowing for adjustment of the suction nozzle component 31 at any position in the horizontal plane to meet the needs of different bonding positions; the electric turntable can drive the suction nozzle component 31 to rotate horizontally, adjusting the foam bonding angle to adapt to the bonding requirements of different curved or inclined surfaces of the pen body; the combination of these two features achieves the linkage of horizontal translation and rotation of the suction nozzle component 31. Combined with the rotational motion of the pen body driven by the rotating component 2, it enables precise control of complex bonding trajectories, improving bonding efficiency and quality.

[0028] In one embodiment, the vision component 4 includes a Z-axis linear module 41 disposed on the cabinet body and a CCD camera 42 that is driven to move up and down by the Z-axis linear module 41, the CCD camera 42 being located above the positioning component 21.

[0029] This design enables precise detection of the pen body's positioning and foam bonding status, providing accurate image data support for the control module and ensuring accurate positioning and qualified bonding quality. Specifically: the Z-axis linear module 41 can drive the CCD camera 42 to move up and down, adjusting the shooting distance between the camera and the pen body to adapt to the shooting needs of different pen body sizes, while finding the optimal shooting focal length to improve image clarity; the CCD camera 42 is located above the positioning component 21, and can directly capture images of the pen body positioning area and the foam bonding area, ensuring that the shooting angle covers the key detection area; through the transmission and analysis of image data, the positioning accuracy before bonding and the quality after bonding can be verified, avoiding product scrap due to positioning deviation or poor bonding.

[0030] In one embodiment, the vision component 4 further includes a ring light 43 disposed outside the lens of the CCD camera 42 and coaxially disposed with the CCD camera 42, the ring light 43 being used to provide supplemental lighting to the shooting area.

[0031] This design optimizes the lighting conditions in the shooting area, improves the clarity and contrast of images captured by the CCD camera 42, and ensures that the control module can accurately identify the pen body positioning status and foam bonding defects.

[0032] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
