Description

  The present invention relates to a method for conveying and supplying a member in a molding die used for manufacturing various molded parts, and an apparatus therefor.

  In a conventional method for conveying and supplying a member in a molding die and its apparatus, in a case where a workpiece made of a flexible and plastic material, that is, a material to be conveyed, for example, a flexible, plastic, and unstable wire is formed by resin molding, It is necessary to hold and fix almost the whole work (wire, etc.) so that it does not move, that is, to position it individually, insert the work piece into the mold, and take it out individually after the molding is complete. The resin of the runner part was cut and separated.

  Accordingly, in order to supply (insert) and carry out (take out) an unstable workpiece into a molding die with high accuracy, an operation by an operator is generally performed. For example, an operation is performed by a robot mechanism having a chuck. At this time, high-precision positioning of the workpiece in the molding die, insertion detection, and detection of unloading of the workpiece from the molding die have been performed using a recognition mechanism using an optical camera or the like.

  As another conventional method, a method using a so-called lead frame is generally used. For example, in Japanese Patent Laid-Open No. 04-290236, the same molding apparatus is used again by twisting a hoop. Japanese Patent Laid-Open No. 06-204275 discloses the contents for reducing the mechanism, and Japanese Patent Application Laid-Open No. 08-216170 describes the contents related to detachment from the molding die. No. 09-001583 discloses the contents related to the positioning of the lead frame, and Japanese Patent Application Laid-Open No. 2000-314226 discloses the contents related to prevention of terminal bending at the time of detachment from the molding die. The present invention relates to a method and an apparatus for performing molding, and these are general methods and apparatuses.

As prior art document information relating to this application, for example, Patent Document 1 is known.

  However, in the configuration of the member conveyance and supply device in the conventional molding die, when the shape of the workpiece to be molded is an unusual shape or a special shape, especially the workpiece itself is flexible and plastic, and there is no strain and the shape is not stable. For example, in the method and apparatus for manually supplying (inserting) a workpiece to be molded directly into the molding die, the operator accurately inserts the workpiece into the molding die. In order to carry out and take out, i.e., transport and supply operations, the productivity is low and the cost is high.

  Alternatively, even if the above operation is performed by a robot, it is difficult to detect the insertion of the workpiece into the molding die and the removal of the workpiece after molding, and even if it is performed using a recognition mechanism, it is complicated. In order to recognize the wire rod of the workpiece, recognition within a relatively wide field of view is necessary, and therefore recognition with low resolution is difficult, and it is difficult to stably detect and detect with high accuracy.

  In addition, if the wire rod, which is a workpiece, is molded in a state where supply (insertion) has been missed into the molding die, it will become abnormal and the device itself will stop, so a return operation such as cleaning the molding die is required. If the recovery time is not completed in a short time, the molding resin in the molding device will be altered, and the molding resin must be removed from the molding device, so-called purging, and the device will be stopped for a long time. This would result in a low-productivity molding device. In the worst case, if the molding is performed in a state where the supply (insertion) of the workpiece wire into the molding die is missed, the molding die may be damaged. .

  Furthermore, when a lead frame, which is a general method, is used, a workpiece is joined to a predetermined position of a lead frame having a positioning hole with high accuracy, and then continuous molding is performed. After molding, after molding, it can be transported by the lead frame in the positioning hole. To carry out (take out) the molded product after molding, the molded product is cut and separated from the lead frame. In addition to the need for a cutting mechanism for that purpose, the lead frame after cutting is discarded. Therefore, the material cost of the discarded lead frame is expensive, and it cannot be said that it is economical from the viewpoint of cost.

  At the time of cutting from the lead frame, for example, as shown in FIG. 18A, a molded resin part 57 is provided at one end of the wire 59, and a molded finished product 58 in which the tip of the wire 59 is not exposed from the molded resin part 57 is obtained. If necessary, as shown in FIG. 18B, when fixing the wire 56 of the workpiece to the lead frame 55, one end and the vicinity of the other end or the center of the wire 56 are joined to the belt portion 60 in the lead frame 55. Otherwise, the wire 56 cannot be joined to the lead frame 55 in a stable state.

  Therefore, as shown in FIG. 18C, when the wire 56 is separated from the lead frame 55 by the separation cutting portion 61 and the separation cutting portion 62, the cutting portion 63 shown in FIG. Since it becomes a cut surface shape like the cutting part 64 shown in FIG.18 (e), when the external appearance of a molded product cannot obtain the wire material of uniform thickness, when the wire material part becomes the external appearance of goods. Is a fatal drawback.

  As described above, when the molded part is practically the appearance of the product, it is difficult to produce with the lead frame, and as described above, the operator manually handles the workpiece to be molded directly into the molding die. It is necessary to use a method of performing direct insertion or a method of performing insertion using a robot having a chuck, and in any case, there is a problem that the method and apparatus are low in productivity, expensive and low in stability. Have.
