Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0030] A fan sealing foam automatic attaching device, such as Figure 1 As shown, it includes: a three-axis robotic arm 1, which is configured to be able to perform rotational movement in the horizontal direction and vertical movement in the vertical direction;

[0031] Roller attachment device 2, such as Figure 3-5 As shown, the roller attaching device 2 includes: along the conveying direction of the foam 25 (the foam is adhered to the release paper, the foam loader is used to load the foam with the release paper, and the release paper receiver collects the release paper remaining after the foam is attached), a foam loader 4, a foam cutting mechanism 5, an attaching roller 6 and a release paper receiver 7 are sequentially provided on the carrier plate 3; wherein the foam loader 4 and the release paper receiver 7 are rotatably connected to the carrier plate 3 and the two are meshed and transmitted through their respective gears, the foam cutting mechanism 5 is configured to cut the foam, the attaching roller 6 is connected to the vertically arranged elastic component 8, and the elastic component 8 is configured to form a vertical elastic force on the attaching roller 6 to drive the foam on the attaching roller to fit the workpiece to be attached; the fixed end of the elastic component 8 is fixedly connected to the vertical output end of the robotic arm 1. The three-axis robotic arm can move in the horizontal and vertical directions. The three-axis robotic arm 1 drives the roller attaching device 2 to move synchronously, which can drive the foam on the roller attaching device 2 to attach the workpiece to be attached. The three-axis robotic arm can achieve precise positioning to avoid attachment deviation, replace manual labor, reduce manpower, and improve product production cycle and pass rate.

[0032] Among them, such as Figure 2 As shown, the three-axis robotic arm 1 includes a first driving mechanism 10 installed on the robotic arm base 9, the first driving mechanism 10 is transmission-connected to a first rotating bracket 11 that rotates laterally, a second driving mechanism is provided at the end of the first rotating bracket 11, the second driving mechanism is transmission-connected to a second rotating bracket 13 that rotates laterally, the end of the second rotating bracket 13 is connected to a lifting mechanism 12 that is vertically downwardly arranged, and the output end of the lifting mechanism 12 is fixedly connected to the carrier plate through a second connecting block 29; wherein, the three-axis robotic arm 1 is installed on the equipment platform 30 through the robotic arm base 9, the first driving mechanism 10 and the second driving mechanism can adopt rotating motors, and the lifting mechanism can adopt lifting cylinders.

[0033] The elastic component 8 includes a first connecting block 14, a connecting shaft 15, a spring 17 and a roller mounting seat 16. The first connecting block 14 is fixed to the carrier plate 3. A vertically arranged connecting shaft 15 is fixed to one end of the first connecting block 14. The connecting shaft 15 is movably mounted on the roller mounting seat 16 (such as Figure 5 As shown, an opening is provided on the roller mounting seat 16, and the connecting shaft 15 is gap-connected to the opening and can move up and down in the opening). The attached roller 6 is rotatably connected to the roller mounting seat 16.

[0034] like Figure 3-5As shown, the roller attachment device 2 also includes a plurality of support columns 18 for supporting the foam. The support columns 18 are fixed to the carrier plate 3. The foam feeder 4 includes a feeding wheel 19 and a first gear 20. The feeding wheel 19 is fixedly connected to the first gear 20 and is rotatably connected to the carrier plate 3 via a first bearing 26. Specifically, a first connecting shaft 27 is fixed to the carrier plate 3, the inner ring of the first bearing 26 is fixedly connected to the first connecting shaft 27, and the feeding wheel 19 and the first gear 20 are fixedly connected to the outer ring of the first bearing 26. The feeding wheel 19 is used to wrap the foam 25 with release paper around it for discharge. The release paper receiver 7 includes a receiving wheel 21 and a second gear 22. The receiving wheel 21 is fixedly connected to the second gear 22 and is rotatably connected to the carrier plate 3 via a second bearing 28.

The foam cutting mechanism 5 includes a telescopic cylinder 23, the fixed end of which is fixed to the carrier plate 3. A cutting blade 24 is fixed to the output end of the telescopic cylinder 23 to cut the foam. When the roller attaching device 2 attaches the workpiece to be attached, the three-axis robotic arm applies vertical downward pressure to the carrier plate, causing the foam on the attaching roller 6 to attach to the workpiece to be attached. During the attaching process, the loading wheel 19 is pulled to rotate and discharge the material. The first gear on the loading wheel engages with the second gear, causing the second gear to rotate and drive the receiving wheel 21 to rotate to receive the release paper. During the attaching process, the control system of the device will pre-program the attachment trajectory and calculate the trajectory length. By controlling the foam cutting mechanism to cut the corresponding length, the three-axis robotic arm is controlled to attach according to the predetermined trajectory.

[0035] In order to identify and record the coordinates of the foam on the carrier plate 3, the device of the present application further includes a lower visual camera 32, which is arranged on the device platform 30 below the roller attaching device 2. Figure 1 As shown, the lower visual camera captures the position of the material to be attached (foam) and sends the captured photo to the control system of the device. The control system determines the position of the material to be attached on the roller attaching device based on the photo information, and controls the three-axis robotic arm to attach according to the programmed trajectory and predetermined length and adjust the attachment position during attachment.

[0036] For easy attachment, Figure 1As shown, the device of the present application also includes an attachment platform 31, which is used to carry the workpiece to be attached. The attachment platform 31 is placed on the platform conveying mechanism to convey the attachment platform device. The platform conveying mechanism is arranged on the lower left side of the equipment platform 30, so that the attachment platform 31 on the platform conveying mechanism is roughly flush with the surface of the equipment platform 30. The platform conveying mechanism includes a rotating motor, the output shaft of the rotating motor is connected to the transmission shaft, and the transmission shaft drives the conveyor belt thereon. The platform conveying mechanism in this application adopts the existing well-known technology, which will not be repeated here. It is also equipped with an attachment carrier positioning grating, which is used to position the attachment platform 31 on the platform conveying mechanism. The attachment carrier positioning grating sends the positioning information to the control system of the device. The control system drives the three-axis robotic arm to move accurately to the attachment platform 31 according to the positioning information to attach the workpiece to be attached on the attachment platform.

[0037] The working process of the fan sealing foam automatic attachment device of the present application is as follows: the three-axis robotic arm 1 drives the roller attachment device 2 to move to the attachment platform 31 on the platform transmission mechanism. When passing the lower visual camera 32, the lower visual camera 32 takes a picture of the roller attachment device 2 and transmits it to the control system of the device. The control system determines the exact position of the foam on the roller attachment device based on the photo information, and controls the three-axis robotic arm to start attaching the foam to the workpiece to be attached according to the pre-programmed trajectory and predetermined length. Figure 6 As shown, after the predetermined length is reached, the foam cutting mechanism 5 is controlled to cut the foam.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features.
