Description

Elbow nozzle for dispensing Technical Field The utility model relates to the technical field of 3C product production equipment, in particular to a bent pipe nozzle for dispensing. Background In the current dispensing industry, most of dispensing nozzles widely popular in the market are of straight tube structures. However, in the actual industrial production scenario, there are special cases in many places where glue needs to be applied. Part of the space is narrow, the common straight pipe nozzle is difficult to penetrate into, and part of the straight pipe nozzle forms a certain angle with the dispensing head, so that the front end of the conventional straight pipe nozzle cannot extend to the parts with the angle with the dispensing head. This results in that the effective glue dispensing operation cannot be performed at these special positions, and the requirement of precise angle glue dispensing cannot be met. For example, in the electronic industry, when surface coating and packaging are performed on a part with a special angle or a part which is not easy to reach, the straight tube nozzle exposes obvious defects, and the work such as fixing of a PCB, bonding of connecting wires, sealing of a precision assembly, protection of an internal circuit and the like is difficult to complete. In the medical field, sealing of medical consumables, component adhesion of medical instruments and the like are also faced with the same problems, and development of dispensing operation at a special position is limited by a nozzle with a common straight tube structure, so that a new dispensing nozzle is needed to solve the problems. Therefore, we propose a pipe bending nozzle for dispensing. Disclosure of utility model The utility model mainly aims to provide a bent pipe nozzle for dispensing, which aims to prevent the problem that the dispensing operation of special positions such as PCB (printed circuit board) fixation, medical consumable sealing and the like cannot be finished in the electronic industry, the medical field and the like because the conventional straight pipe-structure dispensing nozzle cannot perform effective dispensing operation in a narrow space and at a special position with an angle with a dispensing head, so that the applicability and the accuracy of the dispensing operation in a complex scene are improved, and the problems in the background technology can be effectively solved. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: the elbow nozzle for dispensing comprises a steering adjusting mechanism, wherein an angle adjusting mechanism for adjusting an inclination angle is arranged below the steering adjusting mechanism, a connecting mechanism is arranged below the angle adjusting mechanism, a dispensing valve body is arranged on one side of the connecting mechanism, a nozzle body is arranged at the bottom of the dispensing valve body, and an elbow is arranged on the nozzle body; the angle adjusting mechanism comprises a fixed seat, two symmetrical support plates are fixedly connected to the bottom surface of the fixed seat, a worm wheel is arranged between the two support plates, two symmetrical lug plates are fixedly connected to the bottom surface of the fixed seat, a worm is arranged between the two lug plates and above the worm wheel, two ends of the worm penetrate through the lug plates and are connected with the lug plates through bearings in a rotating mode, and the worm is meshed with the worm wheel. By adopting the technical scheme, the steering adjusting mechanism can enable the whole device to carry out steering adjustment in the horizontal direction, and an operator can enable the whole dispensing elbow nozzle to rotate to a proper direction on the horizontal plane by controlling the steering adjusting mechanism, so that the dispensing position can be aligned with a workpiece part needing dispensing, and the horizontal direction positioning preparation is carried out for the subsequent accurate dispensing; When the inclination angle of the dispensing is required to be adjusted, the angle adjusting mechanism plays a role, when the worm rotates, as the two ends of the worm are rotationally connected with the lug plates through the bearings, the worm can flexibly rotate between the lug plates, the worm is meshed with the worm wheel, the worm is driven to rotate by the rotation of the worm according to the worm wheel and worm gear transmission principle, the worm wheel is arranged between the two support plates, the worm wheel is connected with a subsequent connecting mechanism and other parts, the whole lower structure connected with the worm wheel can be changed in inclination angle through the rotation of the worm wheel, the rotation direction and the number of turns of the worm are controlled, the rotation angle of the worm wheel can be accurately controlled, and the accurate adjustment of the inclination angle of the nozzle is r
