Description

Technical Field

[0001] The utility model relates to the technical field surrounding SMT production, in particular to a corner turning machine for an SMT production line. Background Art

[0002] The corner machine in the SMT production line is an automated equipment specially designed to handle printed circuit boards (PCBs) so that they can achieve 90-degree turns in the production line. The corner machine can adapt to various SMT, DIP or assembly production lines to achieve fully automatic turning and docking. The corner machine usually has two modes: straight-through and rotation. It can be quickly switched according to production needs to meet different production layouts and processes.

[0003] Patent document CN209291361U discloses a 350 corner machine, "including a machine body, a corner motor, a corner platform, an operating platform, a plate track and an electric control box. A mounting plate is provided in the middle of the machine body, and a corner motor is provided at the lower end of the mounting plate. The utility model has a reasonable structural design and high practicality. When working, electronic products such as circuit boards enter the plate track in the machine body through the rectangular feed and discharge slots. At this time, the corner motor drives the driven wheel and the corner platform to rotate through the active wheel. When the rotation is aligned with the required production line, the corner motor stops running, and the plate track drives the circuit boards and other electronic products to be transported to the production line. The rotation is flexible, stable, and accurate, and the time-consuming operation is short. At the same time, under the action of the operating platform, the operation is sensitive and convenient, which reduces the workload of employees. This device occupies The small floor area makes it easy to place, and with the help of the maintenance door, it is easy to repair and maintain, which improves the rationality of the connection between the various processing links of the entire SMT production line." However, the 350-degree angle machine in the above-mentioned public document mainly considers the convenience of repair and the rationality of the connection between the various processing links of the entire SMT production line. It does not take into account that the screw translation structure needs to be regularly stopped during long-term continuous work to manually add lubricating oil to it to ensure that the screw translation structure maintains smooth operation and is not worn. However, stopping the angle machine to manually add lubricating oil will increase the workload of the staff and reduce work efficiency, thereby leading to the problem of low SMT production efficiency. Therefore, it is necessary to develop a angle machine for SMT production line, which can automatically add lubricating oil to the screw translation structure without stopping the machine.

The connecting window 27 is used for the rail trolley 6 to position and contact with the rail trolley 6 on the other side to realize the circuit board. The corner machine is mainly used for rotating the circuit board plane by 90 degrees in the automated production line to change the transportation direction of the circuit board. When using the corner machine, the rail trolley 6 of the upper part 2 of the machine body is first aligned with the circuit board and positioned in place, so that the circuit board can be smoothly moved into the rail trolley 6 of the corner machine, and then the rotating platform 4 is driven by the stepper motor 3 to realize a 90-degree rotation, so that the rail trolley 6 is aligned with the rail trolley 6 of the other corner, and then the rail trolley 6 is moved by starting the screw translation structure 5 through the connecting window 27 to approach the rail trolley 6 on the other side to realize the transportation of the circuit board. The position accuracy and repeatability of the screw translation structure 5 are high, and it is more suitable for the corner machine of the SMT production line that requires fine adjustment and translation. It is not taken into account that the screw translation structure 5 needs to be regularly stopped during long-term continuous work to manually add lubricating oil to it to ensure that the screw translation structure 5 keeps running smoothly and is not worn.

The squeezed lubricating oil will drip onto the screw component of the screw translation structure 5 through the oil outlet 9 to automatically oil the screw translation structure 5, ensuring the smooth operation of the screw translation structure 5 without pausing for turning. The machine is manually oiled, which reduces the workload of the staff and improves the working efficiency of the corner machine. When the line module 26 needs to be cooled, the fan blades 23 are installed to facilitate cooling of the line module 26. First, the No. 2 motor 22 is started to drive the fan blades 23 to rotate.
