Dispensing mechanism convenient for angle adjustment

Abstract

The invention discloses a dispensing mechanism convenient for angle adjustment, the dispensing mechanism comprises a support and a dispensing cylinder, one side of the support is provided with a threaded rod and a limiting rod, the middle part of the threaded rod is sleeved with a sliding block, and the outer side of the sliding block is sleeved with a worm wheel; the outer side of the middle of the threaded rod is sleeved with a fixing frame, a worm meshed with the worm gear is rotationally arranged in the middle of the fixing frame, and a first motor fixedly connected with the fixing frame is arranged at one end of the worm. A second motor is longitudinally and fixedly arranged in the middle of the support, the output end of the second motor is sleeved with a driving gear, and one end of the threaded rod is sleeved with a driven gear. The dispensing cylinder is driven to swing by adopting a transmission mode of the worm wheel and the worm, on one hand, the adjustment accuracy of the dispensing barrel can be improved, and on the other hand, the worm wheel and the worm have mechanical self-locking, so that the installation stability of the dispensing cylinder is ensured, the dispensing operation accuracy is improved, the processing cost is saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a glue dispensing device, in particular to a glue dispensing mechanism which is convenient for angle adjustment. Background technique [0002] During the production process of the circuit board, it is necessary to mount the electronic components on the circuit board. Usually, it is necessary to further fix the electronic components and the circuit board body by dispensing, so that the electronic components are not easy to fall off. During the dispensing operation, the operator uses the dispensing cylinder to dispens the glue. Since the dispensing cylinder in the existing dispensing mechanism is mostly a fixed structure, the angle cannot be adjusted according to the actual working conditions, which brings inconvenience to the use. . [0003] Patent No. CN214107672U discloses an angle-adjustable PCB board dispensing mechanism. The patent drives two sets of pulleys to rotate through a motor, and then uses the pulleys to drive the...

[0003] Patent No. CN214107672U discloses an angle-adjustable PCB board dispensing mechanism. The patent drives two sets of pulleys to rotate through a motor, and then uses the pulleys to drive the rotating shaft to rotate, thereby realizing the rotation of the dispensing cylinder through the rotating shaft, and then completing the dispensing cylinder. Angle adjustment, but in actual use, the rotation of the pulley through the synchronous belt is poor in stability, which will cause the dispensing cylinder to shake slightly, which will reduce the accuracy of the dispensing operation, and this patent cannot realize dispensing The left and right adjustment of the cylinder leads to poor flexibility and is not conducive to actual use
