Description

[Technical field]

[0001] The present invention relates to a component pre-inspection device for a hybrid odd-shaped component insertion robot, and more particularly to a component pre-inspection device for a hybrid odd-shaped component insertion robot that automatically distinguishes between good and defective parts supplied from an electronic component feeder to the hybrid odd-shaped component insertion robot before the parts are loaded into the hybrid odd-shaped component insertion robot, and enables the defective parts to be removed. [Background technology]

[0002] Here, background art related to the present invention is provided, which does not necessarily mean that the art is publicly known. Generally, component supply to the hybrid odd-shaped component insertion robot is performed by an electronic component supply machine. As such electronic component feeders, a tape feeder, a tray feeder, a stick feeder, and the like are used. Among the electronic component feeders, the stick feeder divides components arranged in the internal space of a stick according to the shape and number of leads formed on the components, and supplies the components to an irregular component insertion device. A stick feeder generally includes a transport unit that transports the part to a pick-up position so that it can be picked up by the hybrid odd-shaped part insertion robot, a detection unit that detects whether the part can be picked up when it is picked up, a part quantity confirmation unit that detects whether the parts inside the stick are worn out, and a stick replacement unit that replaces an empty stick with a new stick. However, since parts are arranged on the sticks of the stick feeder regardless of whether the parts are defective or not, there is a problem that defective parts are supplied to the irregular part insertion equipment, which causes defects in the final product and other problems. Summary of the Invention [Problem to be solved by the invention]

[0003] The object of the present invention is to provide a component pre-inspection device for a hybrid odd-shaped component insertion robot that automatically distinguishes between good and defective components supplied from an electronic component feeder to the hybrid odd-shaped component insertion robot before the components are loaded into the hybrid odd-shaped component insertion robot, and enables the removal of defective components.

[0004] Furthermore, the problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by a person having ordinary skill in the art to which the present invention pertains from the following description. [Means for solving the problem]

[0005] This section provides a general overview of the disclosure and is not intended to be a comprehensive or all-inclusive disclosure of its scope.

[0006] In order to solve the above problems, the present invention provides a component pre-inspection device for a hybrid odd-shaped component insertion robot that is installed on a transport unit of a stick feeder-type electronic component feeder that moves components to a component pick-up position provided inside odd-shaped component insertion equipment, and the component pre-inspection device for a hybrid odd-shaped component insertion robot includes a camera that takes images of the lower side of the components guided through the transport unit in real time, a gantry robot that picks up defective components from among the components guided through the transport unit and discharges them to the outside, and a control unit that compares a component image of the component taken by the camera with a reference component image stored in a memory to determine whether the component is pass or fail, and operates the gantry robot when determining that the component is defective.

[0007] In the component pre-inspection device for a hybrid odd-shaped component insertion robot of the present invention, a camera is installed under the transfer unit and transmits captured images of the components to the control unit in real time. The transfer unit may be provided transparently so that the camera can capture images of the lower part of the components, or only the part facing the camera may be provided transparently.

[0008] In the component pre-inspection device for a hybrid odd-shaped component insertion robot of the present invention, the gantry robot is installed between the camera and the odd-shaped component insertion device and includes a vacuum suction gripper that picks up defective components, and when the gantry robot receives an operation signal transmitted from the control unit, it brings the vacuum suction gripper into close contact with the defective component to adsorb it, and when the vacuum suction gripper has adsorbed the defective component, it can eject it outside the transfer unit. Effect of the Invention

[0009] According to the present invention, it is possible to automatically distinguish between good and defective parts supplied from an electronic component feeder to the hybrid odd-shaped component insertion robot before the parts are loaded into the hybrid odd-shaped component insertion robot, and to remove the defective parts, thereby not only reducing unnecessary inspection motions in the hybrid odd-shaped component insertion robot, but also providing the effect of increasing the production volume of final products. [Brief description of the drawings]

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a component pre-inspection device for a hybrid odd-shaped component insertion robot according to the present invention will be described in detail with reference to the drawings. However, it is not to be said that the essential technical idea of ​​the present invention is limited in its possible implementation by the embodiments described below, but rather it is made clear that the essential technical idea of ​​the present invention encompasses a range of methods that can be easily proposed by ordinary skilled artisans to replace or modify the embodiments described below based on the essential technical idea of ​​the present invention. Furthermore, the terms used hereinafter have been selected for the convenience of explanation, and therefore, in grasping the essential technical idea of ​​the present invention, they should not be limited to their dictionary meanings, but should be appropriately interpreted in a meaning consistent with the technical idea of ​​the present invention.

[0012] FIG. 1 is a schematic diagram showing a component pre-inspection device for a hybrid odd-shaped component insertion robot according to the present invention. The component pre-inspection device for a hybrid odd-shaped component insertion robot according to the present invention is installed on a transfer section 12 of an electronic component supplyer 10 that moves a component C inside a hybrid odd-shaped component insertion robot 20, i.e., to a position where the component can be picked up. Here, the electronic component feeder 10 may be a typical stick feeder, and the transport portion 12 of the electronic component feeder 10 may be a track or rail on which a guide groove (not shown) for the components C is formed. In addition, since the electronic component feeder 10 supplies the component C to a component pick-up position located inside the hybrid odd-shaped component insertion robot 20 is a well-known technique, a detailed description thereof will be omitted in the present invention.

[0013] As shown in FIG. 1, the component pre-inspection device for a hybrid odd-shaped component insertion robot according to the present invention includes a camera 140, a gantry robot 150, and a control unit 160. First, the camera 140 photographs the components C guided through the conveyor 12 of the electronic component feeder 10 in real time, converts the photographed component image into an electrical signal, and transmits it to the control unit 160 in real time. Preferably, the camera 140 photographs the lower side of the component C being guided through the conveying section 12 of the electronic component supplying device 10, and for this purpose, the camera 140 is installed below the conveying section 12 of the electronic component supplying device 10 as shown in the figure. At this time, the conveying unit 12 of the electronic component supplying machine 10, i.e., the track or rail, may be provided transparently so that the camera 140 can photograph the bottom of the component C, or only the portion facing the camera 140 may be provided transparently.

[0014] As an example, the camera 140 may be a conventional Charge-Coupled Device (CCD) sensor or a Complementary Metal Oxide Semiconductor (CMOS) sensor. The gantry robot 150 picks up defective components C among the components C guided through the transfer unit 12 of the electronic component feeder 10 and ejects them outside the transfer unit 12 of the electronic component feeder 10 . The gantry robot 150 is installed between the camera 140 and the hybrid odd-shaped part insertion robot 20, and includes a vacuum suction gripper 152 that picks up the defective part C.

[0015] In other words, when the control unit 160 determines that the component C photographed by the camera 140 is a defective component C, the control unit 160 transmits an operation signal to the gantry robot 150, and when the gantry robot 150 receives the operation signal transmitted from the control unit 160, the gantry robot 150 brings the vacuum suction gripper 152 into close contact with the defective component C to adsorb the defective component C, and when the vacuum suction gripper 152 has adsorbed the defective component C, the gantry robot 150 ejects the defective component C outside the transport unit 12 of the electronic component supply machine 10. Here, the configuration in which the vacuum suction gripper 152 picks up the defective part C and then removes the picked-up defective part C is well known, so a detailed description thereof will be omitted in the present invention. Furthermore, the present invention does not particularly limit the configuration of the gantry robot 150. However, as long as the gantry robot 150 can perform the above-mentioned operations, the gantry robot 150 may have any configuration and form.

[0016] The control unit 160 controls the operations of the camera 140 and the gantry robot 150 to distinguish whether the component C guided by the transport unit 12 of the electronic component feeder 10 is a non-defective or defective product. That is, the control unit 160 receives the component image signal of the component C transmitted from the camera 140, and compares the component image signal of the component C with a reference image of the component C stored in the memory to determine whether the component C is good or defective. For example, when comparing the reference image with the component image, if component C in the component image is rotated to the left or right of the component in the reference image, it is determined to be defective, and if they are identical, it is determined to be a good product. Also, when comparing the reference image with the component image, if the external shape (damage or bent leads) of component C in the component image does not match, it is determined to be defective, and if they match, it is determined to be a good product.

[0017] If the control unit 160 determines that the component C is defective by comparing the reference image with the component image, it simultaneously transmits an operation signal to the gantry robot 150 so that the gantry robot 150 ejects the defective component C to the outside. The component pre-inspection device for a hybrid odd-shaped component insertion robot according to the present invention, formed in this manner, can automatically distinguish between good and defective components C supplied to the hybrid odd-shaped component insertion robot 20 by the electronic component feeder 10 before the components C are loaded into the hybrid odd-shaped component insertion robot 20, and can remove defective components C, thereby not only reducing unnecessary inspection motions in the hybrid odd-shaped component insertion robot 20, but also increasing the production volume of final products.
