Description

[Detailed Description of the Invention] <Industrial Application Field> This invention can be used to attach a label with written information to an electronic component such as a P-ROM or EP-ROM in which information is written. The present invention relates to a labeling device.

<Conventional technology> Conventionally, as a device for processing this type of electronic component,
A P-ROM writer exists. This P-ROM
A lighter has one or more sockets arranged on a front panel that includes a keyboard, an operating mode indicator, a digital display, and the like. To write information using this P-ROM writer, first insert the model electronic component into the socket, import this into the P-ROM writer as model information, and then
An unprocessed electronic component is inserted into the socket, and the above information is written and processed.

<Problem to be solved by the invention> However, in the case of a P-ROM writer, the number of electronic parts that can be processed at one time corresponds to the number of sockets arranged on the front panel, and it is not suitable for large-volume processing. Not only is this difficult, but it also requires a lot of effort, especially for attaching labels to the surfaces of processed electronic components, which is one of the reasons for the high cost.

To solve this problem, it is also possible to use an automatic label applicator to automatically apply labels to the surfaces of electronic components.

However, conventional automatic labeling devices place multiple articles on a conveyor belt, and then feed and attach labels to the articles in transit (Japanese Patent Application Laid-Open No. 18700/1983), It is necessary to synchronize the timing of conveyance of the article and the feeding of the label, but this kind of timing setting is almost difficult, especially for small articles such as electronic parts. Furthermore, since labels are fed out and pasted onto moving items, if the direction in which the labels are fed out and the direction in which the items move does not match, the labels may wrinkle or be damaged, and the items may shift during the pasting process, resulting in pasting errors. There are problems such as this occurring.

This invention was made by focusing on the above problem, and by adopting a method of automatically attaching labels while electronic parts are stopped, it is possible to accurately and properly apply labels to light and small items such as electronic parts. The purpose of the present invention is to provide a new device for attaching labels to electronic components that can automatically attach labels.

<Means for Solving the Problems> In order to achieve the above object, the present invention includes a stopper for stopping the electronic component in a fixed position provided on an inclined guide for shunting the electronic component, and a stopper for stopping the electronic component at a fixed position. A label pasting device is constructed by a labeler that is disposed so as to be movable back and forth along an inclined guide.

The labeler is wound with a pair of upper and lower reel stop shafts provided above the stop position of the electronic component, and a band-shaped tape provided on one of the reel stop shafts and having a plurality of labels affixed at equal intervals. A reel, a label peeling guide that peels the label from the tape strip by folding the tape strip pulled out from the reel in the upstream direction of the inclined guide in the downstream direction, and a label peeling guide that is disposed on the other reel stop shaft and removes the strip tape after the label has been peeled off. A take-up reel for winding, a second drive mechanism that drives a reel stop shaft on the side where the take-up reel is arranged, and a second drive mechanism located upstream of the label peeling guide to press the peeled label onto the electronic component. The first and second drive mechanisms are configured to set their driving states so that the amount of movement of the labeler in the downstream direction and the amount of movement of the tape strip in the upstream direction are equal. ing.

<Operation> The electronic component is stopped by the stopper at the position of the labeler by shunting the tilting guide by its own weight.
After that, the movement of the labeler in the downstream direction and the movement of the strip tape in the upstream direction are started,
The label is peeled off by a label peeling guide and sent onto the electronic component.

In this case, since the labeler and the strip tape transfer the same amount, the label is left on the stopped electronic component and is then affixed to the surface of the component by the pressing action of the presser roller. This ensures that the label is affixed to the correct position on the electronic component, and the label is not wrinkled or damaged.
Also, pasting errors due to misalignment of parts do not occur.
