[0029] Please see Figures 1-10 This utility model discloses a sheet material auxiliary material bonding machine for bonding sheet material auxiliary material 200 with adhesive backing onto product 300, wherein one surface of the sheet material auxiliary material 200 is bonded with adhesive backing, and the other side of the sheet material auxiliary material 200 is covered with a release film.

[0030] The sheet material applicator includes a machine base 100 and a material picking mechanism 10, a conveying mechanism 20, an applicator 30, a product transport mechanism 40, and a control system installed on the machine base 100. The control system is used to control the material picking mechanism 10, the conveying mechanism 20, the applicator 30, and the product transport mechanism 40 to work together.

[0031] Please see Figure 5 and Figure 6The material handling mechanism 10 includes a magazine assembly 112, a material handling robot 12, a peeling assembly 14, and a transfer assembly 13. The magazine assembly 112 is movable along the Z-axis and the sheet material 200 is stacked on the magazine assembly 112. The material handling robot 12 is used to pick up the sheet material 200 from the magazine assembly 112. The peeling assembly 14 is used to peel off the release film of the sheet material 200. The transfer assembly 13 is used to move the material handling mechanism. The robotic arm 12 transfers the sheet material 200 with the release film removed to the loading position. The conveying mechanism 20 drives the bonding mechanism 30 to the loading position to pick up the sheet material 200 with the release film removed and move it to the bonding position for bonding operation. The product transport mechanism 40 moves the product 300 without bonding material to the bonding position for the bonding mechanism 30 to perform bonding operation and removes the product 300 with bonding material located at the bonding position.

[0032] Please see Figure 3 and Figure 4 The machine base 100 is provided with a second slide rail 111 along the Z-axis direction. The magazine assembly 112 can slide along the second slide rail 111 under the drive of the third motor 113 to carry the sheet material 200 upward to the gripping stroke range of the picking robot 12. In this embodiment, the third motor 113 drives the magazine assembly 112 to slide along the Z-axis direction via a transmission belt.

[0033] Please see Figure 5 The material handling robot 12 includes at least two independently controlled first cylinders 122 and a suction cup assembly 121 installed at the movable end of each first cylinder 122. The suction cup assembly 121 is used to adsorb and grasp the sheet material 200. In this embodiment, by extending and retracting the at least two independently controlled first cylinders 122 at different frequencies, the suction cup assembly 121 installed at the movable end of the first cylinder 122 can be moved up and down alternately, thereby avoiding the simultaneous adsorption of multiple layers of sheet material 200.

[0034] The transfer assembly 13 includes a third slide rail 131 extending along the X-axis, a sliding block 133 slidably disposed on the third slide rail 131, and a fourth motor 132 driving the sliding block 133 to slide along the third slide rail 131. In this embodiment, the fourth motor 132 drives the sliding block 133 to slide along the X-axis via a transmission belt. The first cylinder 122 of the picking robot 12 is fixedly mounted on the sliding block 133 so that, driven by the fourth motor 132, the sliding block 133 drives the picking robot 12 to move the sheet material 200 it has gripped along the X-axis to the loading position.

[0035] Please continue reading. Figure 5 and Figure 6 The peeling assembly 14 includes a positioning plate 144 slidably disposed on the machine base 100 along the Z-axis, a second cylinder 145 for driving the positioning plate 144 to slide, a gripper 146 slidably disposed on the positioning plate 144 along the Z-axis, and a third cylinder 143 for driving the gripper 146 to slide. The gripper 146 moves towards or away from the positioning plate 144 in cooperation with the second cylinder 145 and the third cylinder 143.

[0036] When the peeling assembly 14 needs to clamp the release film of the sheet material 200, the second cylinder 145 and the third cylinder 143 respectively drive the positioning plate 144 and the gripper 146 to move in opposite directions to separate them; when the release film enters between the gripper 146 and the positioning plate 144, the second cylinder 145 and the third cylinder 143 respectively drive the positioning plate 144 and the gripper 146 to move towards each other to clamp and fix the release film, and then the second cylinder 145 and the third cylinder 143 respectively drive the positioning plate 144 and the gripper 146 to move synchronously downwards to separate the release film from the sheet material 200.

[0037] Please continue reading. Figure 6 The peeling assembly 14 is also rotatably equipped with a rotating pressure rod 142 and a first motor 147 that controls the rotation of the rotating pressure rod 142. When the gripper 146 and the positioning plate 144 clamp the release film, the first motor 147 controls the rotating pressure rod 142 to rotate towards the spring clip assembly 112 to abut against the release film. At the same time, the suction cup assembly 121 of the material picking robot 12 adsorbs the sheet material 200 and moves it, completely separating the sheet material 200 from the release film. During the process of the suction cup assembly 121 adsorbing the sheet material 200 and moving it upward, the release film falls into the waste bin 16.

[0038] In this embodiment, a fixing block 148 is detachably installed at one end of the positioning plate 144 that abuts against the gripper 146. When the positioning plate 144 and the gripper 146 move toward each other, the gripper 146 abuts against the fixing block 148. The fixing block 148 is made of Teflon material, which on the one hand prevents the sheet material 200 from being crushed or scratched, and on the other hand, the fixing block 148 is detachable, making it easy to replace when it reaches the end of its service life.

The negative pressure unit 32 is connected to a suction hole 312 through the suction plate 31 via a ventilation pipe 33. More specifically, the suction plate 31 has a recessed suction groove 311 on the side that absorbs the sheet material 200. The suction hole 312 is located in the suction groove 311. When the suction plate 31 picks up the sheet material 200, the sheet material 200 is absorbed in the suction groove 311.

[0043] Please see Figure 10 The product transport mechanism 40 includes a loading conveyor 41, a unloading conveyor 42, and a labeling table 43 located between the loading conveyor 41 and the unloading conveyor 42, with the labeling position located on the labeling table 43.

The third photographing device 70 is used to photograph the product 300 at the applicator position without applicator and the product 300 with applicator, and feed back the position information to the control system. In this embodiment, the first photographing device 50 and the third photographing device 70 are located above the machine platform 100 and photograph the sheet material applicator 200 and the product 300 from top to bottom. The second photographing device 60 is located below the machine platform 100 and photographs the sheet material applicator 200 grasped by the applicator mechanism 30 from bottom to top. The control system uses the results of the first photographing device 50, the second photographing device 60, and the third photographing device 70 to assist in positioning the sheet material 200 and the product 300. The third photographing device 70 can also determine whether the sheet material 200 that the product 300 is attached to is qualified based on the feedback positioning information.
