Motion mechanism

Abstract

The invention discloses a motion mechanism for controlling the motion of an automatic detector camera, comprising a base plate (6) provided with a groove, a screw rod fixing seat (5) arranged in the groove, a slide rail (1) which is connected with the base plate (6) in a sliding way, and a fixing plate (2) for fixing the slide rail (1), wherein the fixing plate (2) is also provided with a nut fixing seat (4); and the nut fixing seat (4) is arranged on the side of the screw rod fixing seat (5). The invention has beneficial effect that the motion mechanism has low manufacturing cost and is not easy to damage.

Description

technical field [0001] The invention relates to a movement mechanism, in particular to a movement mechanism used for a camera of an automatic detector. Background technique [0002] The final process of soldering is inspection. Due to the defects of soldering joints, the solder joints need to be inspected after the production is completed. There are roughly two types of welding inspections: one is pre-welding inspection, that is, checking the surface of the base metal, solder , flux, etc. meet the appropriate welding conditions; the second is post-welding inspection, that is, checking whether the welding is reliable and whether there are welding defects. Post-welding inspection can not only find all defects through strict inspection to ensure the quality of shipped products, but also find large quantities of defective products in time to prevent subsequent defective products from continuing to occur. The most important thing is the analysis of defective products after weldin...

Problems solved by technology

One method of visual inspection is to rely on the inspector to use the visual method to inspect, which is a waste of time and manpower. The other is to use automatic inspection equipment to capture images of solder joints, identify the images of solder joints and compare them with characteristic images. Compare to judge the quality of solder joints

[0004] In the automatic detection equipment, a movable camera is used to move to the position of the target object for image collection, and then the computer recognizes and compares the images; in the prior art, in the movement mechanism of the camera, in order to make it run smoothly, among them The accessories must require very high machining accuracy to ensure that the movement mechanism can run smoothly. If the processed groove is too deep or too shallow, exceeding its allowable tolerance (plus or minus 0.01mm), it may cause the screw fixing seat and the nut to be fixed. If the seats are not coaxial, the screw rod will be deformed to the left or right due to the force. When the screw rod moves back and forth, it will be loose and tight at times, unstable, and in severe cases, the screw rod and the nut will be stuck, resulting in Its kinematic mechanism is damaged

The processing precision of the accessories is high, which leads to high production costs, and if the accessories are slightly deformed during use, it will cause damage to the mechanism and increase the use cost of the product
