Description

[Detailed description of the invention] (Industrial field of application) The present invention is designed to hold the bobbin when transferring the coil bobbin between the robot that supplies and discharges the coil bobbin to and from the coil winding machine and the winding machine. The present invention relates to a coil bobbin delivery jig for preventing the bobbin from deforming during wiring.

(Prior Art) Conventionally, all operations such as supplying a bobbin to a coil winding machine and removing a wound coil bobbin from the winding machine have been performed manually.

The method of holding a coil bobbin in this type of winding machine is to attach a cylindrical jig holder to the tip of the main shaft driven by a motor, and to wind the coil bobbin using the inside cross section of the jig holder's cylinder. The coil bobbin has a rectangular or round shape approximately equal to the cross section of the cylindrical part,
A simple square or round rod jig that fits inside this tube is inserted. Then, the coil bobbin is inserted into this jig and winding is performed.The jig holder and the jig are fixed with screws, or the jig is tapered and press-fitted, and the coil bobbin is attached to one end of the jig. The plate that holds the bobbin is fixed by screws.

(Problem to be solved by the invention) Even if the winding machine is automated as mentioned above, feeding and discharging the coil bobbin to the winding machine is still a manual process.
Although there are jigs that can be attached to winding machines that are time-consuming to operate during winding, there are no jigs that are suitable for robots to feed and discharge coil bobbins.

Moreover, as the automation of winding machines has progressed, it has become possible to wind wire onto multiple bobbins at the same time, so if you want a robot to perform the operation of supplying and discharging coil bobbins to the winding machine, you can use the recently miniaturized coil bobbin. It is expected that the handling will be much more efficient than manual handling, and will be handled without errors.

Rather than holding the coil bobbin as is in the robot hand, it is better to insert the coil bobbin into a jig and hold it without worrying about deformation due to the bobbin being held, so the coil bobbin can be made from thinner material to be lighter and smaller. be able to.

Further, if the coil bobbin is transferred to a winding machine in this state and the coil bobbin is wound while being inserted into the jig, there is an advantage that the bobbin will not lose its shape due to the winding. However, a jig suitable for such usage does not yet exist.

The present invention solves this problem and allows the coil bobbin and jig to be delivered together with the coil bobbin inserted between the robot that supplies and discharges the coil bobbin to and from the winding machine, and the coil bobbin and the jig to be delivered together. To provide a coil bobbin delivery jig that allows the coil bobbin to be transferred while the coil bobbin is inserted into the jig.

(Means for Solving the Problem) In order to achieve the above object, the coil bobbin delivery jig of the present invention has a rod-shaped coil bobbin fitted on one side of the collar-shaped plate to fit into the cylindrical part of the coil bobbin to be inserted. An insertion part is provided, a rod-shaped held part that is compatible with the structure of the workpiece holding part of the robot hand is provided on the other side of the brim-shaped plate, and the coil bobbin insertion part is fitted with a jig holding part of the winding machine. It has a structure in which the held part has a recess for being locked into the work holding part of the robot hand, and the brim-like plate has a protrusion provided on the coil bobbin.
