Description

Technical Field

[0001] The utility model relates to the technical field of chip placement machines, in particular to a chip placement mechanism for producing electronic components. Background Art

[0002] A chip mounter, also known as a "patch machine" or "surface mount system," is a device used to place components at high speed and precision. It is a critical and complex piece of equipment in the entire SMT production process. In a production line, it is located after a dispensing machine or solder paste printer, accurately placing surface mount components on PCB pads by moving a placement head. A patent search revealed publication number CN112770528B, which discloses a chip placement mechanism for a chip mounter. The mechanism features a replacement slot and positioning blocks, facilitating rapid replacement of chip heads and accommodating different sizes. This avoids delays caused by slow replacements and unusable components due to size differences. The mechanism also includes a moving slot, a material hopper, and a manipulator, enabling manual loading, reducing workload and facilitating faster completion of tasks. A first rotating shaft, connecting rod, second rotating shaft, rotating rod, and push rod facilitate movement of the material hopper during material loading and unloading by the manipulator, facilitating material removal and reducing work time.

[0003] When in use, the existing patch machine drives the patch gun head to move up and down through the patch cylinder. Each time a patch is placed, the corresponding patch cylinder will perform a telescopic movement, which will aggravate the wear between the piston rod and the sealing ring, thereby affecting the sealing of the patch cylinder. The patch cylinder and the patch gun head are fixed in the mounting frame. When the patch cylinder or the patch gun head fails, they cannot be quickly disassembled and assembled, which makes it inconvenient to repair and maintain the patch cylinder and the patch gun head. In order to solve the above problems, this application proposes a patch mechanism for the production of electronic components. Utility Model Content
