Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of patching machine nozzle, and relates to an adjustable patching machine nozzle for patching machine. BACKGROUND

[0002] The patching machine nozzle (also known as a suction nozzle or a suction tip) is a key component in the patching machine, mainly used for picking up and placing electronic components in the automated patching process.

[0003] A publicly disclosed patent in China (publication number: CN216795627U) discloses an adjustable patching machine nozzle for patching machine, which includes a top plate, a gas cylinder fixedly connected to the bottom of the top plate, an output end of the gas cylinder fixedly connected to a rotating frame, an electric sliding rail rotatably connected to the inner side of the rotating frame, a sliding plate slidably connected to the bottom of the electric sliding rail, and a suction nozzle movably connected to the bottom of the sliding plate. The disclosed patent adjusts the inclination angle of the electric sliding rail through the rotation of the first motor, and aligns the center of the rotating shaft with the suction point of the suction nozzle to prevent the suction point from deviating during rotation of the electric sliding rail, thereby avoiding the situation that the inclination of the suction nozzle leads to inaccurate patching position. However, this kind of suction nozzle cannot adjust the turning position of the patch simultaneously during moving the patch. If the suction nozzle is used to pick up and place electronic components between two mutually perpendicular conveying belts, the placement angle of the electronic components relative to the two different conveying belts will also be different, which will affect the subsequent work of the electronic components.

[0012] Further, a transmission rod is arranged to penetrate the connecting plate, and the gear B and the gear C are arranged at two ends of the transmission rod.

[0013] Further, a through hole is formed in the connecting plate for the transmission rod to penetrate, a limiting table is arranged around the side wall of the transmission rod on the upper side of the connecting plate, and the outer diameter of the limiting table is greater than the diameter of the through hole.

[0018] Compared with the prior art, the adjustable paster nozzle of the paster has the following beneficial effects:
