[0022] This equipment is suitable for the laminating process of foam on the back shell of large-size TVs. The edges of the back shell of the TV need to be pasted with left foam tape, right foam tape, and top foam tape. Foam tape 100 uses 3mm wide and 1.8m long ultra-long thin strip foam. Due to its extremely narrow width and ultra-long size, it cannot be rolled into a roll structure. It can only be pressed and pasted manually, and ultra-long rolls cannot be rolled. If this ultra-thin and ultra-long foam tape is rolled up, the roll material will spread out.

[0023] This equipment uses foam strips in the form of fixed-length sheets, and relies on a robot to realize the automated attachment process. Multiple sheets are arranged at equal intervals on the bottom film 11, and the bottom film 11 is stored in the silo 21. Each time a piece of bottom film 11 is taken out, the bottom film 11 must be initially positioned (such as Figure 4 or 8, with the aid of a visual camera), and then clamping both ends of the bottom film 11 (as shown in Figure 4 Or 5, with visual camera cooperation), then the 1.9m long negative pressure suction plate 4 on the robot 3 sucks the single foam strip on the bottom film 11. (As shown in Figure 4 As shown, all are coordinated by visual cameras. The suction process adopts a method of fixing one end and lifting the other end (such as Figure 2 and 3 As shown in the figure, the slender suction rod forms an acute angle with the bottom film 11. During the suction process, the bottom film 11 will bend in an arch shape due to adhesion. The foam adhesive strip on the bottom film 11 will be separated from the bottom film 11 from the end as the slender suction rod is lifted. The bottom film 11 will return to a flat state after being completely separated from the foam adhesive strip. The slender suction rod will return to a horizontal state after the foam adhesive strip is completely separated from the bottom film 11. The robot 3 transfers the foam tape 100 to the target position and performs the attachment action.

[0024] After the attachment is completed, the robot 3 applies the pressure wheel 16 integrated next to the negative pressure suction plate 4 to the attached foam to re-press it so that it is firmly bonded. (The existing technology usually adopts manual pasting) After the foam tape 100 is pasted, the release paper on the surface (such as Figure 7 As shown in FIG. 1 , there are two release paper clamping claws 206, one of which moves to one end of the foam tape 100, and the release paper is clamped by the rotation of the cylinder. The release paper is lifted up with the release paper clamping claws 206, and then separated from the foam tape 100, forming an acute angle gap.

[0025] The second release paper clamping air gripper 206 moves to the sharp angle gap between the foam tape 100 and the release paper in an open state (maintaining the open state), and then performs a translational motion, and uses the concave clamp 207 to pull the release paper, so that the remaining release paper is pulled off the foam tape 100, and the pulled release paper is clamped at a suitable position before the end of the release paper. The release paper is discarded into the waste bin (the waste bin is located below the X-axis double-actuator linear slide 201), and the film tearing action is completed.

[0026] The translation, lifting, and displacement (rotation) actions of the two release paper clamping claws 206 are realized by the following mechanisms: two Z-axis servo module lifting platforms 202 are installed on the X-axis double-motor linear slide 201, and each Z-axis servo module lifting platform 202 is installed with a set of Y-axis servo module slides 203, and a rotating cylinder 204 is installed on the Y-axis servo module slide 203. The rotating cylinder 204 is connected to the release paper clamping claws 206 via a swing arm 205.

[0027] In summary, the present invention provides a foam tape 100 installation device. To solve the problem that extra-long and extra-thin foam tapes cannot be laid in a roll-up form, an extra-long negative pressure suction plate is used to peel off the foam tape in a fixed length from the base film to realize automatic installation. At the same time, with the cooperation of visual positioning, not only the production efficiency is greatly improved, but also the installation accuracy is significantly improved.
