[0030] Embodiment 1

[0031] The sealing plate metal sheet plays a role in closing the air conditioner indoor unit. Since the copper pipe of the evaporator of the indoor unit needs to be connected to the condenser of the outdoor unit, it will cause the air conditioner indoor unit to form an obvious opening. In order to form a closed space in the indoor unit, the sealing plate metal sheet is an essential component of the air conditioner indoor unit. With the popularity of automatic equipment in the workshop, the sealing plate metal sheet has realized automatic pre-assembly by robot to achieve unmanned production, but the robot equipment can only complete the action of sucking or grabbing the sealing plate metal sheet, and cannot arrange the incoming materials in order, which is not conducive to saving manpower.

[0032] In view of the above problems, the automatic conveying mechanism for the sealing plate metal sheet disclosed in the embodiment, Figures 1-4 includes a conveying belt 1, a limiting piece and a suction cup assembly 4. The conveying belt 1 is provided with an inclined stacking channel 2 for placing the sealing plate metal sheet to be conveyed above the conveying belt 1. The limiting piece is arranged at the descending end 22 of the inclined stacking channel 2. The sealing plate metal sheets to be conveyed are limited by the limiting piece and stacked along the length direction of the stacking channel 2. The suction cup assembly 4 is directed towards the descending end 22 of the stacking channel 2. A blanking port 5 is left between the suction cup assembly 4 and the descending end 22. The blanking port 5 is communicated with the conveying belt 1. A controller (not shown in the figure) is connected with the suction cup assembly 4. When the sealing plate metal sheet is conveyed, the suction cup assembly 4 is controlled to sequentially suck the sealing plate metal sheet at the descending end 22 of the stacking channel 2 and move it to the blanking port 5. The sealing plate metal sheet falls into the conveying belt 1 through the blanking port 5, and the conveying belt 1 sequentially outputs the sealing plate metal sheet.

[0033] The automatic conveying mechanism for the sealing plate metal sheet has the following effects and advantages: the inclined stacking channel 2 is used to orderly stack the sealing plate metal sheets on the stacking channel 2, and the inclined descending end 22 of the stacking channel 2 is provided with a limiting piece, which can position the sealing plate metal sheets at the descending end 22, facilitating subsequent orderly taking out of the sealing plate metal sheets; the suction cup assembly 4 is provided with a blanking opening 5 between the descending end 22, and the suction cup assembly 4 can suck the sealing plate metal sheets at the descending end 22 in a set direction and drop the sealing plate metal sheets from the blanking opening 5 to the conveying belt 1, so that the sealing plate metal sheets are dropped to the conveying belt 1 at a fixed angle, without the need for manual adjustment of the conveying angle of the sealing plate metal sheets, and the robot can grasp the sealing plate metal sheets, thereby saving labor and cost. The automatic conveying mechanism for the sealing plate metal sheet is arranged above the conveying belt 1 and does not occupy additional space, and has a compact structure, which is suitable for large-scale production application.

[0034] The method for using the automatic conveying mechanism for the sealing plate metal sheet is as follows: a plurality of sealing plate metal sheets are stacked on the stacking channel 2, and under the limiting action of the limiting piece, the sealing plate metal sheets are orderly stacked and limited at the descending end 22 of the stacking channel 2; the controller controls the suction cup assembly 4 to suck the sealing plate metal sheets at the descending end 22; after the suction cup assembly 4 is released, the sealing plate metal sheets are dropped from the blanking opening 5 to the conveying belt 1, so that the sealing plate metal sheets are dropped to the conveying belt 1 at a fixed angle, and the robot grasps the sealing plate metal sheets on the conveying belt 1.

[0035] In this embodiment, the limiting piece includes at least two magnets 3, and the at least two magnets 3 are respectively fixed to the two sides of the stacking channel 2. When the stack of sealing plate metal sheets is located at the descending end 22, the two side ends of the sealing plate metal sheets are magnetically attracted and fixed by the magnets 3 on the two sides of the stacking channel 2.

[0036] The two sides of the stacking channel 2 are provided with baffle edges 10, and the magnets 3 are fixed to the inner sides of the baffle edges 10. When the sealing plate metal sheets are stacked, the two side ends of the sealing plate metal sheets will touch the magnets 3, and the two side ends of the sealing plate metal sheets are magnetically attracted, thereby limiting the two side ends of the sealing plate metal sheets. The magnetic attraction not only has the effect of magnetic attraction, but also facilitates the suction cup assembly 4 to quickly take down the sealing plate metal sheets from the magnetic attraction, and the suction cup assembly 4 can quickly complete the suction of the sealing plate metal sheets.

[0037] In this embodiment, the suction cup assembly 4 includes a gas cylinder 41, the piston rod of the gas cylinder 41 is connected with a suction cup 42, and the suction and release end of the suction cup 42 points to the descending end 22 in the horizontal direction.

[0038] In use, the movement of the piston rod of the gas cylinder 41 can control the movement of the suction cup 42, so that the suction cup assembly 4 generates a movement action, and the suction cup 42 can generate a suction or release effect. When suctioning, the sealing plate metal sheets are grasped, and when releasing, the sealing plate metal sheets are dropped.

[0047] After using the photoelectric sensor, when it is detected that the material waiting position 8 is less than, for example, three sealing plate sheet metal parts, a feedback signal is fed back to the front end to control the suction cup assembly 4 to suck the sealing plate sheet metal part, so as to ensure that the material waiting position 8 always maintains the material waiting state.
