[0002] In automated glass production, robots are typically used to transfer stacked glass sheets one by one onto a conveyor belt. However, because robots require considerable space, it's difficult to place the glass horizontally onto the conveyor belt in confined production lines. If the robot directly releases the glass, it will impact the conveyor belt. Therefore, manual unloading is currently used. However, manual unloading is labor-intensive and inefficient.

[0022] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0023] Please refer to Figure 1 As shown, this utility model discloses a film unloading device, including a conveyor belt 1 and a receiving assembly 2. The conveyor surface of the conveyor belt 1 has multiple avoidance areas. The receiving assembly 2 includes a first rotating shaft 21, a swing rod 22, and a first suction cup 23. The first rotating shaft 21 is disposed below the conveyor surface of the conveyor belt 1, and the axis of the first rotating shaft 21 is parallel to the conveyor direction of the conveyor belt 1. Multiple swing rods 22 are arranged at intervals along the axis of the first rotating shaft 21. The swing rods 22 are located below the avoidance areas, and each swing rod 22 is provided with a first suction cup 23 for vertical movement.

[0024] Working principle: During the unloading process, robot 4 moves the glass to a designated position and tilts it. Then, receiving assembly 2 drives the first rotating shaft 21 to rotate, causing the swing arm 22 to swing towards the glass with the first suction cup 23 until the first suction cup 23 is parallel to the glass and adheres to the glass surface. Next, the first suction cup 23 picks up the glass, and robot 4 releases the glass. Then, the first rotating shaft 21 drives the swing arm 22 to reset. During the reset process, when the swing arm 22 rises so that it is parallel to the transmission surface of the conveyor belt 1 and located within the conveyor belt 1, the first suction cup 23 is positioned above the transmission surface of the conveyor belt 1 and parallel to the transmission surface of the conveyor belt 1. Then, the first suction cup 23 descends so that the glass can be placed stably on the conveyor belt 1.

[0025] It is worth noting that, please refer to Figure 1 As shown, the receiving assembly 2 also includes a first driver 25 for driving the first rotating shaft 21 to rotate. Specifically, the first driver 25 can be a motor directly connected to the first rotating shaft 21, or it can be a reciprocating device with a connecting rod hinged to the first rotating shaft 21. The reciprocating device controls the forward and reverse rotation of the first rotating shaft 21 by driving the connecting rod to push out or retract. The reciprocating device can be a pneumatic cylinder, electric cylinder, hydraulic cylinder, or other device with a linear reciprocating movable end.

[0026] The conveyor belt 1 has a conveying surface composed of multiple spaced rollers 3. Specifically, each roller 3 includes a third rotating shaft 31 and multiple support wheels 32 mounted on the third rotating shaft 31. By using the support wheels 32 to support the glass, the contact area between the rollers 3 and the glass can be reduced, minimizing the risk of scratches on the glass surface caused by debris remaining on the rollers.

[0027] In some implementations, please refer to Figure 1 As shown, the receiving assembly 2 also includes a second rotating shaft 24 parallel to the first rotating shaft 21. The first suction cup 23 is connected to the second rotating shaft 24, and the first suction cup 23 is hinged to the swing arm 22. By rotating the second rotating shaft 24, the first suction cup 23 can move up and down on the swing arm 22.

[0028] It is worth noting that, please refer to Figure 1 As shown, the receiving assembly 2 also includes a second driver 26 for driving the second rotating shaft 24 to rotate. Specifically, the second driver 26 can be a motor directly connected to the second rotating shaft 24, or it can be a reciprocating device with a connecting rod hinged to the second rotating shaft 24. The reciprocating device controls the forward and reverse rotation of the second rotating shaft 24 by driving the connecting rod to push out or retract. The reciprocating device can be a pneumatic cylinder, electric cylinder, hydraulic cylinder, or other device with a linear reciprocating movable end.

[0029] In some embodiments, a vacuum sensor (not shown in the figure) is provided on the first suction cup 23. The vacuum sensor is used to detect the vacuum level of the first suction cup 23 to determine whether the first suction cup 23 is effectively adsorbing the glass.

[0030] In some embodiments, a pressure sensor (not shown) is provided on the swing arm 22. During the process of the first rotating shaft 21 driving the first suction cup 23 to adhere to the glass, the pressure sensor is used to sense the resistance of the first suction cup 23 to the glass, so as to avoid over-pressing the glass and causing damage to it.

[0031] In some implementations, please refer to Figure 1 and Figure 2 As shown, the aforementioned unloading device also includes a robot 4 disposed on the side of the conveyor belt 1, and the first rotating shaft 21 is used to drive the swing arm 22 to swing toward the robot 4. The robot 4 is disposed on the side of the conveyor belt 1 to facilitate the transfer of glass to the conveyor belt 1.

[0032] It is worth noting that the choice of robotic arm 4 depends on the complexity of the glass transfer, and can be a four-axis robot, a six-axis robot, a seven-axis robot, or other devices with multiple degrees of freedom of movement.

[0033] In some implementations, please refer to Figure 2 As shown, the end effector of the robot 4 is equipped with a second suction cup 41. The robot 4 uses the second suction cup 41 to grasp the glass.

[0034] In some embodiments, a vacuum sensor (not shown) is provided on the second suction cup 41. The vacuum sensor is used to detect the vacuum level of the second suction cup 41 to determine whether the second suction cup 41 is effectively adsorbing the glass.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
