Problems solved by technology

[0006] However, in the conventional device disclosed in the above-mentioned Patent Document 1, since a substrate recognition camera with a narrow field of view that captures images of tiny marks (fiducial marks) marked on the substrate is directly used to align the positioning holes on the support table The image recognition of support pins is time-consuming and inefficient because they are photographed one by one.

Embodiment Construction

[0032] An example of the best embodiment of the present invention will now be described with reference to the drawings.

[0033] figure 1 and figure 2 The screen printing device of the present invention (the screen printing device to which the supporting pin identification device of the present invention is applied) is schematically shown, figure 1 is the front view of the printing device, figure 2 is a plan view of the printing device. In order to clarify the direction, the X-axis, Y-axis and Z-axis are shown in the figure.

[0034] The screen printing device shown in these figures (hereinafter simply referred to as the printing device) applies a paste such as cream solder to a predetermined position of the printed circuit board W (hereinafter referred to as the substrate W) and simultaneously applies the paste to the printed circuit board W (hereinafter referred to as the substrate W). A device with an inspection function for checking the state, which has a frame 10, a s...

Abstract

A method and device for identifying support pins, determining the use area (U0) corresponding to the size of the substrate as the work object in the support plate (36), and then assigning the use area (U0) to two objects that can be photographed at the same time and are close to each other A plurality of unit areas (U1) corresponding to the field of view of the camera of the wide-angle field of view of a plurality of positioning holes, utilize the camera to shoot the positioning hole (36a) of each unit area (U1), and judge the positioning hole ( The presence or absence of support pins in 36a) identifies the arrangement of support pins in the use area (U0). According to the present invention, the production efficiency of the substrate is improved by efficiently performing image recognition on the support pins.

Description

technical field [0001] The present invention relates to a screen printing device for applying a paste such as cream solder on a substrate such as a printed circuit board, or a surface mounter for mounting components on the substrate, and the substrate is supported by support pins from the back side thereof. The identification method of the support pin and its identification device in the device performing the work, and a screen printing device and a surface mounter having the support pin identification device. Background technique [0002] When mounting electronic components on the front and back of a printed substrate, print (coat paste) on one side of the substrate in the mounting line, mount the electronic components, and then guide the electronic components in a reflow furnace. Then, the substrate is turned over, and then the other side surface of the substrate is printed, installed, conducted and fixed on the installation line. In devices such as screen printing device...
