[0030] In order to make the present invention more obvious and easy to understand, preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.

[0031] Example

[0032] like Figure 1-9 As shown, the utility model provides a body-in-white welding four-door line automatic sound insulation pad pasting equipment, which includes:

[0033] Floating drawer mechanism 2 for conveying sound insulation pads;

[0034] An automatic glue-tearing mechanism 3 for tearing off the isolation film of the film on the sound insulation pad;

[0035] A floor-standing visual inspection component 5 for detecting whether the isolation film of the film on the sound insulation pad has been torn off;

[0036] A visual sound insulation pad gripper 1 for grabbing the sound insulation pad and attaching it to the door outer panel, which is connected to the industrial robot arm;

[0037] A waste collection bucket device 4 for collecting isolation membranes;

[0038] A gluing platform 6 is used for gluing the sound insulation pad to the door outer panel vehicle part.

[0039] The floating drawer mechanism 2 includes a movable drawer 2-2 fixed on a floor-standing welding frame platform 2-1. The movable drawer 2-2 includes an outer frame and a movable component. The outer frame is divided into a material preparation area and a pickup area along the movable direction, and a limit safety component 2-3 is provided between the two. A pickup position floating compensation component 2-4 is provided at the bottom of the pickup area. The floor-standing welding frame platform 2-1 is provided with a drawer position sensor for monitoring whether the movable component is located in the pickup area and a car part photoelectric sensor for monitoring whether there is a sound insulation pad on the movable component. The pickup position floating compensation component 2-4 includes guide sleeves 2-4-1 respectively provided at the bottom of the outer frame of the movable drawer 2-2 and the floor-standing welding frame platform 2-1. The lower guide sleeve 2-4-1 is fixedly connected to the lower end of the guide column 2-4-2, and the upper guide sleeve 2-4-1 is slidably connected to the upper end of the guide column 2-4-2. The guide column 2-4-2 is covered with a spring 2-4-3, and the two ends of the spring 2-4-3 are respectively in contact with the two guide sleeves 2-4-1. When picking up items, the visual sound insulation pad grabber 1 will press the sound insulation pad and move downward, and the spring 2-4-3 is compressed to provide an upward force, so that there is no gap between the suction cup on the visual sound insulation pad grabber 1 and the sound insulation pad in the movable drawer 2-2, thereby achieving an adsorption effect.

[0040] The automatic glue peeling mechanism 3 includes a cylinder assembly 3-2 fixed on a floor-standing welding bracket 3-1, and the cylinder assembly 3-2 includes a polyurethane pressure block, which is connected to the pressure arm of the pressure cylinder.

[0041] The visual sound insulation pad grabber 1 includes a suction cup assembly 1-1 fixed on a fixed frame, a roller telescopic assembly 1-2 that can be telescoped up and down, a brush telescopic assembly 1-3 that can be telescoped diagonally, and a visual detection assembly 1-4. The suction cup assembly 1-1 includes six downward suction cups 1 arranged in a 2×3 manner, and suction cups 2 located on the left and right sides of the suction cup 1 facing forward and backward respectively; the roller telescopic assembly 1-2 and the brush telescopic assembly 1-3 both include telescopic cylinders with guide rods; the visual detection assembly 1-4 includes an ISV visual camera 1 and a distance sensor.

[0042] The waste collection bucket device 4 includes a waste collection bucket 4-2 fixed on a welding height-enhancing frame 4-1.

[0043] The glue sticking platform 6 is provided with a supporting assembly 6 - 1 for supporting the door outer panel component 6 - 2 .

[0044] The floor visual inspection component 5 includes an ISV visual camera 2 5-2 fixed on a floor welding bracket 2 5-1. The sound insulation pad is photographed by the ISV camera 2 5-2. Because the sticker and the sound insulation pad have different colors, it is used to determine whether the isolation film of the sticker around the sound insulation pad has been torn off. When the isolation film is successfully torn off, the floor visual inspection component 5 is used, and the robot performs the subsequent normal process. When the isolation film is not torn off, the floor visual inspection component 5 will feedback a signal to the robot, and the robot will throw the sound insulation pad into the waste collection bucket 4-2.

[0045] The process is:

[0046] 1. Manually take out a pack of sound insulation pads from the material box, tear off the wrapping paper manually, then put a pack of sound insulation pads into the material box, and manually push the material box into the work station. The sensor will detect that the material box is in place, and manually lock the material box from the outside to prevent the material box from moving.

[0047] 2. The robot moves with the gripper to the top of the material box and takes a visual photo to determine the position of the sound insulation pad in the material box. The gripper can know how far to move downward through the distance measuring sensor on the gripper. When the proximity switch on the gripper has a signal, the suction cup on the gripper will adsorb and take the pad out of the material box.

[0048] 3. After the gripper removes the liner, it moves to the tearing table. The clamping unit on the tearing table will press a corner of the sticker, and use the robot's trajectory to slowly tear the sticker off the liner. The torn sticker will fall into the waste collection bucket under the tearing table.

[0049] 4. The robot moves to the visual photography position with the gripper, and takes a visual photo of the sticker. If the sticker is not torn off, the visual system will determine it and then feedback the signal to the robot. The robot will throw the sound insulation pad into the waste collection bucket and take the sound insulation pad from the material box again. If the visual photography determines that the sticker has been completely torn off, the robot will move to the gluing table with the gripper.

[0050] 5. The glue sticking gripper will first move the sound insulation pad to a position 5mm above the glue sticking table, and use the telescopic cylinder on the gripper to drive the pressure wheel to stick a narrow side of the sound insulation pad to the outer panel of the car body first. Then the pressure wheel will retract, and another telescopic cylinder on the gripper will carry a brush to press down on the pad. The robot's trajectory is used to simulate the state of manual pad sticking to automatically stick the pad. The suction cup of the gripper that adsorbs the pad will be slowly released to reduce the suction of the suction cup on the pad, and also reduce the noise of the suction cup. Finally, when all the sound insulation pads are stuck on the outer panel, the process is completed, and the robot returns to the home position for the next round of process.
