Method and device for positioning and transporting objects

The present invention relates to a positioning method and device, and more particularly to a method and a device for positioning and transporting an object in a strip-shaped carrier tape member provided with a positioning hole.

A method and apparatus for positioning and transporting an object in a conventional manner, for example, in the field of transporting and positioning a sheet-shaped carrier tape provided with a positioning hole in an LED electronic component packaging machine, the transport and positioning technique which has been disclosed, such as the announcement number TW594905 The patent method for positioning a moving object and a device for transporting or stopping a sheet-like conveyed object (ie, a carrying belt) having an opening, which is mainly performed by a set of upper and lower corresponding rollers a limiting means for restricting the object to be transported or releasing the restriction; and performing a positioning means by a positioning pin having a conical head to determine the position of the object to be conveyed; when the corresponding upper and lower rollers are released When the object to be conveyed is restricted, the positioning pin having the conical head is inserted into the opening of the object to be conveyed to position the object to be conveyed.

In addition, the prior art publication No. TW594905 "Method and Apparatus for Positioning and Transporting Objects" also provides a method for transporting and positioning a carrier tape in an LED electronic component packaging machine, including: transporting a sheet-like conveyance having an opening The transfer procedure of the object, which stops after reaching the predetermined position And a restriction program for positioning the object to be moved to a predetermined position when the object to be conveyed is stopped, to limit or release the object to be conveyed when the object to be conveyed is stopped; and repeating at least the object to be conveyed at least once After the stop, the restriction of the conveyed object is released, and the operation of restricting the conveyed object is again performed.

The patent publication No. TW594905, "Method and Apparatus for Positioning and Transporting Objects", provides a method for transporting and positioning a carrier tape in an LED electronic component packaging machine. However, in order to perform positioning during transport, a first implementation must be performed. The program for restricting the upper and lower rollers of the group to release the restriction on the object to be conveyed can insert the positioning pin having the conical head into the opening of the object to be conveyed to position the object to be conveyed; or After the conveyed object is stopped, the restriction of the conveyed object is released and positioned, and the object to be transported is again restricted; therefore, the positioning of the object to be transported must be established in the upper and lower corresponding rollers of the group. After the restriction on the object to be transported, it will take a considerable amount of time because the roller is released from the restriction of the object to be transported. This is a non-competitive production process for a large number of LED electronic component packaging operations requiring high efficiency. .

That is, an object of the present invention is to provide a method of positioning and transporting an object that can be positioned by the object to be conveyed without releasing the restriction on the object to be conveyed.

Another object of the present invention is to provide an apparatus for positioning and transporting an object that can be positioned by a conveyed object without releasing the restriction on the object to be conveyed.
