The unloading robot is driven by a transverse drive mechanism to move along the transverse guide rail.

[0006] The unloading robot includes a slide block slidably connected to a transverse guide rail. The bottom of the slide block has a support plate. The left and right ends of the support plate are respectively provided with left and right guide rails arranged in the left and right directions.

Connecting seats are slidably connected to the two front and rear guide rails. The connecting seats are driven to move on the front and rear guide rails by a front and rear position adjustment mechanism. Short side clamping mechanisms are fixed at the connecting seats.

[0007] In the unloading station, there are four industrial vision cameras arranged in a rectangular shape with their apex corners directly above the unloading table.

[0010] Furthermore, the long-side clamping mechanism and the short-side clamping mechanism have the same structure, both including a lifting cylinder and a finger cylinder. The push rod end of the lifting cylinder is set downwards, and the bottom of the push rod end of the lifting cylinder is connected and fixed to the finger cylinder through a connecting plate. The clamping directions of the long-side clamping mechanism and the short-side clamping mechanism are perpendicular to each other.

[0011] Furthermore, both the left-right position adjustment mechanism and the front-back position adjustment mechanism are screws driven by servo motors.

[0019] As shown in Figures 1-5, the present invention discloses a visual inspection and unloading device for an automatic spacer strip attaching machine. An unloading platform 1 is provided at the unloading station, and a conveyor belt 2 is spaced apart on the side of the unloading platform 1. A crossbeam 3 is horizontally arranged above the unloading platform 1 and the conveyor belt 2. A transverse guide rail 4 is fixed along the length of the crossbeam 3. An unloading robot 5 is slidably connected to the transverse guide rail 4. The unloading robot 5 is driven by a transverse drive mechanism 6 to move along the transverse guide rail 4. The position positioning of the unloading robot 5 is achieved by feedback positioning using a position switch.

[0020] The unloading robot 5 includes a slide block 51 slidably connected to a transverse guide rail 4. The bottom of the slide block 51 has a support plate 52. The left and right ends of the support plate 52 are respectively provided with left and right guide rails 53 arranged in the left and right direction. Support beams 54 are slidably connected to the two left and right guide rails 53. The support beams 54 are driven by the left and right position adjustment mechanism 55 to move on the left and right guide rails 53. Long side clamping mechanisms 56 are fixed at both ends of the support beams 54. The front and rear ends of the support plate 52 are respectively provided with front and rear guide rails 57 arranged in the front and rear direction. Connecting seats 58 are slidably connected to the two front and rear guide rails 57. The connecting seats 58 are driven by the front and rear position adjustment mechanism 510 to move on the front and rear guide rails 57. Short side clamping mechanisms 59 are fixed at the connecting seats 58. The left and right position adjustment mechanism 55 and the front and rear position adjustment mechanism 510 are both screws driven by servo motors. Taking the left-right position adjustment mechanism 55 as an example, the screw is threadedly connected to the middle of the support beam 54. The servo motor drives the screw to rotate, thereby moving the support beam 54 on the left and right guide rails 53, thus adjusting the position of the long side clamping mechanism 56. The front-back position adjustment mechanism 510 has the same structure as the left-right position adjustment mechanism 55, only the direction is different. The specific working structure and principle will not be described in detail.

[0021] Four industrial vision cameras 7 are arranged in a rectangular shape with their apexes positioned directly above the unloading platform 1 in the unloading station. The lenses of the four industrial vision cameras 7 face downwards and correspond to the four apexes of the display frame placement slots on the unloading platform 1. The four industrial vision cameras 7 collect the size and position information of the four apexes of the display frame and feed it back to the unloading robot 5. If there is a positional deviation, the unloading robot 5 adjusts the positions of its long side clamping mechanism 56 and short side clamping mechanism 59 to ensure the accuracy of clamping the display frame.

[0022] The industrial vision camera 7 has a ring light source 8 located directly below the lens. The ring light source 8 is symmetrically distributed around the lens, which can provide uniform diffused light and improve the imaging quality of the industrial vision camera 7.

[0023] The transverse drive mechanism 6 includes a servo motor and a synchronous belt mechanism. The drive pulley of the synchronous belt mechanism is driven to rotate by the servo motor. The slide 51 of the unloading robot 5 is connected and fixed to the transmission belt of the synchronous belt mechanism through a connecting block. The servo motor drives the synchronous belt mechanism, which, together with the unloading robot 5, accurately transfers the display frame onto the conveyor belt 2.

[0024] The long-side clamping mechanism 56 and the short-side clamping mechanism 59 have the same structure, both including a lifting cylinder and a finger cylinder. The push rod end of the lifting cylinder is set downwards, and the bottom of the push rod end of the lifting cylinder is connected and fixed to the finger cylinder through a connecting plate. As shown in Figure 5, the long-side clamping mechanism 56 is used to clamp the long side of the display frame, while the short-side clamping mechanism 59 is used to clamp the short side of the display frame. Obviously, the clamping directions of the long-side clamping mechanism 56 and the short-side clamping mechanism 59 are perpendicular to each other.

[0025] In this utility model, the unloading platform 1 is a movable structure that intermittently enters the unloading station through a rotating structure to realize assembly line production.

[0026] The working principle of this utility model is as follows: the unloading platform 1 enters the unloading station, the unloading robot 5 moves to the top of the unloading platform 1, and the long side clamping mechanism 56 and the short side clamping mechanism 59 on the unloading robot 5 respectively clamp the corresponding side of the display frame; then, the unloading robot 5 moves to the top of the conveyor belt 2 and places the display frame clamped on it on the conveyor belt 2 to complete one unloading action.

[0027] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
