Description

Technical Field

[0001] The utility model relates to the field of back panel processing equipment, in particular to an automatic pad clamping device for a display back panel. Background Art

[0002] The back panel of a display primarily supports and bears the weight of the display, so most back panels are stamped and formed in one piece. Once the back panels are produced, they are typically stacked in a palletized manner for transport.

[0003] The existing backboards are generally stacked with pads at the corner ends of the backboards (of course, it is not limited to the corner ends, it can also be in the middle of the backboard). By stacking the pads on each other, the gaps between the backboards are avoided and stacking is convenient.

[0004] When the backboard needs to be produced and assembled, the protective pad needs to be taken out. The existing clamping equipment generally includes two parts, one is the backboard clamping device, and the other is the protective pad clamping device, which are coordinated through two spaced devices.

[0005] However, because the existing backboards are stacked, the span requirements for the backboard clamping device and the pad clamping device are relatively large. The larger the mechanical radius, the lower the production efficiency. At the same time, how to put down the backboard smoothly and whether the front or backboard is facing up according to needs is the key to backboard transportation. Utility Model Content

[0006] The main purpose of the utility model is to propose an automatic pad clamping device for the display back panel, which aims to realize the transfer of the display back panel and take out the pad together, so as to realize the transportation and loading of the back panel as required, and effectively improve the assembly efficiency.

[0007] To achieve the above-mentioned purpose, the present invention provides an automatic pad clamping device for a display back panel, comprising:

[0008] A material stack, wherein the material stack is provided with a receiving device, the receiving device is provided with a receiving frame, the receiving frame is used to prevent the stacked backboards, and the receiving device can drive the stacked backboards to move vertically;

[0009] A multi-axis robotic arm comprising a base, a first swing arm horizontally pivotally mounted on the base, a second swing arm pivotally mounted on the first swing arm, and a third swing arm pivotally mounted on the second swing arm, the third swing arm being provided with a rotating arm, a driving end of the rotating arm being provided with a base, and the base being provided with a frame;

[0010] The second swing arm can swing 180 degrees with the top of the first swing arm as the fulcrum;

[0011] A suction cup clamping device, which is arranged at the bottom wall of the frame and is used to clamp the back panel;

[0012] The corner end material taking device includes a transverse moving structure provided on the upper wall of the frame, a longitudinal moving structure provided on the transverse moving structure, a first vertical telescopic motor provided on the longitudinal moving structure, and a bidirectional clamping motor provided on the driving end of the first vertical telescopic motor. The driving end of the bidirectional clamping motor is provided with two clamping claws that move relative to each other.

[0013] The corner end material taking device is provided with at least four groups.

[0014] A material unloading area, the material unloading area is used to place the taken-out pads;

[0015] Conveyor belt, a conversion clamping device is provided on one side of the conveyor belt, the conversion clamping device includes a vertical moving frame and a conversion frame provided at the driving end of the vertical moving frame, and the lower wall of the conversion frame is provided with an adsorption seat,

[0016] When the multi-axis robotic arm flips the back panel to face up, the back panel is opposite to the lower wall of the conversion frame, and the vertical movable frame can drive the adsorption seat to approach the back panel and clamp it.

At the same time, the first vertical telescopic motor drives the bidirectional clamping motor to move to the position of the protective pad and enables the clamping claw to clamp the protective pad. Then the multi-axis robot drives the back panel to move to the unloading area, the first vertical telescopic motor moves downward, and the clamping claw pushes the protective pad into the unloading area. Finally, the second swing arm of the multi-axis robot swings 180 degrees with the top of the first swing arm as the fulcrum, so that the front of the back panel is facing up, and then the back panel is facing down, and is moved to the conveyor belt through the conversion clamping device, so that the back panel is transported upward to the assembly process.
