Description

Technical Field

[0001] The utility model relates to the technical field of SMT surface patch transportation, and specifically, to a belt transportation device for SMT surface patches. Background Technique

[0002] SMT patching refers to the abbreviation of a series of process flows processed on the basis of a PCB. The PCB (Printed Circuit Board) is a printed circuit board, and SMT is the abbreviation of Surface Mounted Technology. It is the most popular technology and process in the electronic assembly industry. After the SMT surface patching is completed, it needs to be transported to the subsequent processing area through a transportation device;

[0003] Currently, when transporting SMT surface patches, the SMT surface patches are usually placed on the top of the belt, and the driving motor is used to drive the belt to rotate. The belt drives the SMT surface patches to move to achieve the function of belt transportation. However, in the actual operation process, the conveying speed of the belt is usually relatively fast, and the SMT surface patches may fall off from the top of the driving wheel, resulting in the SMT surface patches being damaged, increasing the transportation cost, and unable to effectively prevent falling;

[0004] Therefore, we provide a belt transportation device for SMT surface patches. Content of the Utility Model
