Description

Electronic component image capturing device and job classification device thereof

The invention provides a method for taking the image surface of the opposite electronic component by using a plurality of image capturing devices in the stroke of shifting the electronic component of the transfer carrier in the first direction, so as to effectively reduce the detection of the transferred electronic component. An electronic component image capturing device that activates timing and paths, thereby saving inspection time and improving production efficiency.

Nowadays, electronic components have undergone multiple processing procedures in the production process. In order to ensure product quality, in order to ensure the quality of the products, in addition to the electrical testing of the internal circuits, the appearance inspection operations are also performed. And the so-called 5S visual inspection usually refers to the visual inspection of the five faces of the electronic component (except for the top surface adsorbed and transferred by the pick and place device) to check the electronic components during the process or transfer process. Whether the spacing or length of the contact points meets the standard, or whether the electrical contacts are damaged, solder balls, stains, etc., and then screen out good electronic components to eliminate defective products.

Please refer to the first, second, and third figures, which are partial schematic views of the electronic component appearance detecting operation device, which is disposed on the machine table 11 with a stage 12 capable of being displaced in the X direction to carry the electronic component to be detected. 13. A shifter 14 is displaced in the XZ direction, and the electronic component 13 to be detected is taken out on the stage 12, and transferred to an image taking mechanism 15 for image capturing operation, and then transmitted through a controller (not shown). The analysis is compared to determine whether it is a good product. The image capturing mechanism 15 is provided with an image taking member 151 which is a CCD, and the bottom surface of the electronic component 13 can be imaged from the bottom up and passed through the controller. The analysis is performed to determine whether the bottom surface of the electronic component 13 is in compliance with the standard, and a frame 152 is disposed above the image capturing member 151, and refraction is respectively disposed on the four inner peripheral sides of the frame 152. Taking the image mirror 153; when performing the appearance inspection operation of the electronic component 13, The shifter 14 first shifts the electronic component 13 to be detected above the frame 152 by X-direction displacement, and then shifts the Z-direction downward to move the electronic component 13 to be detected into the inside of the frame 152. Between the four prisms 153, since the four inner peripheral side prisms 153 can visualize the four sides of the electronic component 13 to be detected, when the image capturing member 151 focuses the four mirrors 153, In the image, the images of the four sides of the electronic component 13 to be detected can be obtained, and through the analysis and comparison of the controller, it is determined whether the four sides of the electronic component 13 are in compliance with the standard, and then the screen is in good condition. The electronic component 13 is used to eliminate the defective product; after the appearance inspection operation is completed, the shifter 14 is displaced upward in the Z direction to move the detected electronic component 13 out of the frame 152, and then the X-direction displacement is to detect the detected electronic The component 13 is transferred to the next mechanism; however, the image capturing mechanism 15 has the following problems to be improved in use:

1. When performing the detecting operation of the electronic component 13, the shifter 14 must first shift the electronic component 13 into the frame 152 of the image capturing mechanism 15 in the XZ direction to perform the image capturing operation, but after the image capturing is completed. The shifter 14 must be moved in the XZ direction to move the electronic component out of the frame 152 of the image taking mechanism 15, so that the shifter 14 moves the electronic component 13 into and out of the image capturing mechanism 15 to increase the overall device. The working time caused the problem that the production efficiency could not be improved.

2. Since the frame 152 of the image taking mechanism 15 is only moved into one electronic component 13 at a time, the feeder 14 moves into only one electronic component 13 to the frame 152 each time to perform an image capturing operation, and other electronic components are temporarily placed. The station 12 waits for feeding, so that the inspection operation is slow and time consuming. If the number of electronic components to be detected in a batch is large, it takes a long time to detect the operation time, which causes a problem that the production efficiency cannot be improved.
