Problems solved by technology

However, in the process of clamping the silicon steel sheets, due to manual operation, the pressing force applied to the silicon steel sheets is inconsistent, and it is easy to cause the air between the silicon steel sheets to not be completely discharged with the excess insulating varnish. Bubbles remain in the insulating varnish layer, causing the transformer to resonate and vibrate during use, shortening the service life of the transformer

Embodiment 1

[0028] like Figure 1 to Figure 6 As shown, the top of the frame 1 forms an included angle of 10° with the horizontal plane, and two vertical support plates are arranged on both sides thereof, which are respectively the left support plate 3 and the right support plate 2, and the two support plates are provided with positioning holes 11 and the upper shaft hole 26.

[0029] The overturn frame 4 is a rectangular frame formed by connecting the upper beam 22, the left longitudinal beam 23, the lower beam 24 and the right longitudinal beam 25 successively, and is installed horizontally between two support plates, and can rotate relative to the frame along the horizontal axis. Its two sides are connected with the connectors passing through the upper shaft holes 26 of the two support plates. The right longitudinal beam of the overturn frame 4 is provided with a first position hole 10 and a second position hole 9, and the inner surface of the left longitudinal beam 23 is a side surfac...

Embodiment 2

[0041] like Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the overhead pushing device is a top cylinder, and five top cylinders are installed and fixed on the upper beam of the overturning frame in a random distribution.

[0042] The invention is easy to operate and convenient to use. When the iron cores are stacked, the mutual vertical relationship between the contact surfaces between the flip frame and the flip plate can be used to quickly locate. By using machinery instead of manual operation, it avoids the gap between the silicon steel sheets caused by manual operation. Residual air bubbles lead to resonant vibration of the transformer core, thereby prolonging the service life of the transformer core.

Abstract

The invention provides a robot for iron core stacking. The machine comprises a machine frame, a rollover stand, a rollover plate, overhead pushing devices, a side arrangement pushing device, a locking device and a rollover plate power device. The rollover stand is provided with a load bearing surface, side blocking surfaces and a covering surface, the load bearing surface and the side blocking surfaces are used for iron core stacking, the covering surface is matched with the rollover plate in covering motion, and the rollover stand is installed on the machine frame and can rotate opposite to the machine frame along the horizontal axis; the overhead pushing devices are installed on the upper portion of the rollover stand; the side arrangement pushing device is installed on the side portion of the rollover stand or located on the side portion of the rollover stand; the locking device is installed on the machine frame and used for locking the opposite angle between the rollover stand and the machine frame; the rollover plate is provided with a stacking reference surface, the rollover plate and the motion part of the rollover plate power device are connected together, and the roller plate can rotate relative to the motion part of the rollover plate power device. Manual operation is replaced by the machine, the phenomenon that resonant oscillation happens to a transformer core caused by the fact that bubbles are left between silicon steel sheets due to manual operation is avoided, and the service life of the core is prolonged.

Description

technical field [0001] The invention relates to a stacking machine, in particular to a transformer iron core stacking machine. Background technique [0002] At present, commonly used transformer cores are generally made of silicon steel sheets. A group of silicon steel sheets of the same specification and height are soaked in insulating varnish and stacked neatly, and the excess insulating varnish between each silicon steel sheet is squeezed out through manual clamping, shifting, and flipping processes. In this way, the air between the silicon steel sheets is discharged, and the silicon steel sheets are bonded with insulating varnish to complete the assembly of the transformer core. However, in the process of clamping the silicon steel sheets, due to manual operation, the pressing force applied to the silicon steel sheets is inconsistent, and it is easy to cause the air between the silicon steel sheets to not be completely discharged with the excess insulating varnish.
