Description

TECHNICAL FIELD

[0001] The present application relates to the field of sheet metal part processing and conveying, and particularly relates to an automatic conveying device for processing of refrigerator sheet metal parts. BACKGROUND

[0002] Refrigerator sheet metal parts (such as side plates, door bodies, back plates, etc.) are usually made of cold-rolled steel sheets, stainless steel or galvanized sheets, and have the characteristics of large size, thin thickness and easy deformation. In the automatic production line, the sheet metal parts need to be flipped and conveyed between different conveying racks to complete the processes of stamping, bending, welding, etc.

[0003] The common flipping and conveying method currently used is to drive a rotating shaft with a driving assembly (servo motor or air cylinder), and a plurality of support shafts are installed on the rotating shaft. A plurality of suction members (which can be suction cups or electromagnets) are arranged at the bottom of the support shafts. After the suction members adsorb the sheet metal parts, the rotating shaft is flipped by 180 degrees to flip the sheet metal parts onto another conveying rack. In order to ensure that the sheet metal parts can be accurately transferred when the horizontal shaft rotates, a groove matching the horizontal shaft is formed on the conveying rack to limit the movement track of the rotating shaft. However, this structure design has certain deficiencies.

[0004] Because the groove limits the position of the horizontal shaft, the use position of the suction members is relatively fixed. When the sheet metal parts with a relatively large thickness are adsorbed and flipped, and the adsorption range of the plurality of suction members on the same support shaft exceeds the size of the sheet metal parts, some suction members will not be in contact with the sheet metal parts and will be in an idle state, which will reduce the adsorption force on the sheet metal parts with a relatively large thickness, and the sheet metal parts with a relatively large thickness will easily fall off during the flipping process, thereby reducing the protection of the sheet metal parts. In addition, when the sheet metal parts with a relatively small thickness are adsorbed and flipped, and the end positions of the left and right sides of the sheet metal parts are not in contact with the suction members, the end of the sheet metal part lacking adsorption support will easily bend and deform under the action of gravity during the flipping process of the sheet metal part, thereby further reducing the protection of the sheet metal part.

[0044] Referring to Figure 1 and Figure 5 , the inside of the hollow plate 23 is provided with an adjusting assembly for adjusting the position of the suction accessory one and the suction accessory two. The adjusting assembly includes two rotating shafts 26 rotatingly arranged inside the hollow plates 23 on the left and right sides and symmetrically distributed front and back, the top end of the rotating shaft 26 penetrates out of the hollow plate 23 and is connected with the bottom of the corresponding rotating plate 233, the outside of the rotating shaft 26 is fixedly provided with a plane gear two 27, the corresponding two plane gear two 27 are engaged, the bottom of the hollow plate 23 on the left and right sides is fixedly provided with a motor two 28, and the output shaft of the motor two 28 is connected with the bottom end of the corresponding rotating shaft 26.
