positioning method

Abstract

The present invention relates to a positioning method, which is used to locate a feature central point of a component to be positioned to a positioning target. The method includes the following steps: an image capture step; an image processing step, performing image processing on the image ; a step of searching for a feature center point, using the image processed image to search for a screen feature center point; a step of calculating the difference between the feature center point and the positioning target; a step of automatically positioning the motor according to the difference; a search for the feature center Point, calculate the difference between the feature center point and the positioning target again; and a step of judging whether the difference falls within the allowable error range, if so, complete the positioning, if not, execute the automatic positioning step again until the positioning is completed. The invention can accurately locate the center of the probe at the target position, save positioning time and reduce cost, and is very suitable for practical use.

Description

technical field [0001] The invention relates to a positioning method, in particular to a positioning method for the probe which can accurately locate the center of the probe at the target position, save positioning time and reduce cost. Background technique [0002] The function of the chip socket (IC Socket) is to electrically connect the plurality of protruding terminals (pins or leads) of the chip (the chip is the chip, hereinafter referred to as the chip) to the plurality of welding pads (pads) of the circuit board, so as to carry out testing. [0003] According to various chips, there are also various forms of chip sockets, please refer to Figure 1A and Figure 1B as shown, Figure 1A It is a structural schematic diagram of a chip socket in the prior art, Figure 1B yes Figure 1A sectional view of the structure. The chip socket 1 has an upper surface 10, and the upper surface 10 includes a positioning surface 11 for accommodating a chip (not shown). A plurality of...

Problems solved by technology

The conventional way of visually aligning the center of the probe 12 takes a lot of time and thus increases the cost

[0007] It can be seen that the above-mentioned existing positioning methods obviously still have inconvenience and defects in terms of method and use, and need to be further improved urgently

In order to solve the above problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general positioning method has no suitable method to solve the above problems. The relevant industry is eager to solve the problem, so it is urgent to provide a positioning method, so that the center of the probe can be accurately positioned at the target position, and save positioning time and reduce costs
