Description

An apparatus and method for detecting the failure of the bending angle of a gripper}

The present invention is to check the defect of the gripper for holding and fixing the electronic components such as resistors, capacitors, etc. in the state of being inserted into the printed circuit board preliminarily until soldering in the soldering process. Apparatus and method, wherein the gripper is bent in the appropriate form by a plurality of continuous rolled to use the unrolled roll (roll), each gripper is inserted into the printed circuit board and then cut, If there is a bad bending during insertion of the gripper on the printed circuit board, it is difficult to insert the gripper. Furthermore, electronic parts such as resistors and capacitors may not be inserted into the gripper, or may not be fixed after insertion. The present invention relates to a gripper defect inspection apparatus and an inspection method for reducing a defect rate in a substrate production process by preventing bending defects from occurring in the gripper manufacturing process. Conventional defect inspection method according to the manufacturing device of such a gripper was forced to rely on the screening inspection by the naked eye of the operator, the present invention is in addition to the manufacturing device of the gripper when the bending failure occurs during the operation of the gripper, The present invention relates to a device and a method for detecting a failure to cut off the entire power supply to a mechanical device for manufacturing a gripper so that no more defects occur.

Referring to Figure 1, the gripper material (2) is wound on the first roller (1) before bending it is moved by a pitch of a predetermined interval and transferred to the mold workbench (3) and the lower mold (5) installed on the workbench As the process proceeds gradually by the up / down press operation of the upper mold 4 while passing through the gripper of a desired shape is formed. Here, the shape of the gripper is gradually made because the shape is not simple and the desired shape can not be obtained by a single process or two or three processes. It becomes. The grippers of good quality that are completed by the mold work and are formed in a strip shape are wound on the second roller (6), counting rolls of a certain length or a certain number of grippers, cutting them, and finally moving to the place where the grippers are used. Will be shipped.

FIG. 2A is a view for explaining an essential part of a normal gripper after bending in FIG. 1. FIG.

Referring to FIG. 2A, a piercing hole 9 formed by an up / down press operation of the upper mold 4 is placed at a predetermined interval in the gripper material 2 passing through the mold worktable 3, and the piercing hole ( Between 9) there are terminals 7 which are bent in the vertical direction by a bending process. And pitch holes 8 are formed at regular intervals on both sides of the outer portion of the gripper material (2). Referring to the conventional gripper bending process having the configuration as described above, the gripper material (2) is conveyed by a certain amount as the pitch formed in the pitch hole (8) through the process of several steps and finally the terminal (7) Is molded. After the terminals 7 are molded, the gripper material 2 is left with a wide piercing hole 9 as finally shown.

FIG. 2B is a view for explaining a shape of a gripper having a bad bending state in FIG. 1; FIG.

Referring to FIG. 2B, some of the terminals are not bent as shown in (A) and some of the terminals are inferior in bending as shown in (B). Typically, the bending process is omitted, and defects such as (B) are caused when the stroke of the upper and lower presses of the upper mold 4 is poor in the bending process and the process of the process. This occurs when the mold is damaged. The defect inspection method according to the conventional manufacturing process has to rely on the screening inspection by the naked eye of the operator without a separate defect inspection device. Therefore, the gripper is transported at a very high speed by a press operation that proceeds at a high speed, whereas the inspection speed of the inspector cannot be followed by the naked eye. Were generated, and these were inevitably fatal to the reliability of the defect inspection.

The present invention has been made in view of the above problems, and connects / attaches a gripper defect inspection device that can automatically inspect whether a bending state is poor for grippers that have been pressed by a progressive mold. Therefore, it is possible to prevent the production of a product with a bad bending angle, so that only good quality grippers can be produced and shipped, and only good quality grippers can be put / worked on a printed circuit board. do.
