Description

Technical Field

[0001] The utility model relates to the technical field of AOI equipment storage, in particular to a storage and alignment precision mechanism. Background Art

[0002] AOI equipment is an optically based automated inspection device used for PCB quality inspection in the electronics manufacturing industry. It uses a high-definition camera to scan the PCB and capture images, which are then compared with qualified parameters in a database to identify product defects.

[0003] Current AOI equipment can cause misalignment between the rings when removing and placing them back during the collection process. Human eye alignment and stacking, without any reference, can lead to slight deviations in the ring angles, causing the placed chips to be out of alignment with their previous alignment. The far end can even come into contact with the previous row of chips, causing anomalies. The machine itself lacks a positioning fixture, so the rings cannot be removed, creating significant inconvenience during small-batch aggregation of multiple products. Therefore, a specialized collection mechanism, combined with a software-based rotation mechanism, and standardized operating procedures were developed to minimize operational anomalies. Utility Model Content

[0004] The purpose of this utility model is to provide a precise storage alignment mechanism to address the problem raised in the background art above. During the storage process, current AOI equipment often experiences misalignment of the storage ring after removal and return. Human eye alignment and stacking, without any reference judgment, can cause slight deviations in the ring angle, causing the placed chips to be out of alignment with the previous line, and potentially contacting the previous row of chips at the far end, causing anomalies. The machine itself lacks a positioning fixture, so the ring cannot be removed, creating significant inconvenience in small-batch aggregation operations involving multiple varieties.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0027] See also Figure 1-3 As shown, this embodiment is a precise storage and alignment mechanism, including:

[0028] The main body component 1 includes a circular base 101, the outer wall of the top of the circular base 101 is symmetrically connected to the circular placement platform 102, the outer wall of the circular placement platform 102 is equidistantly opened with scales 103 around the circumference, the outer wall of the circular placement platform 102 is fixedly connected to a limit plate 104, the outer wall of the circular base 101 is symmetrically fixedly connected to a fixed seat 106, an adsorption hole 105 is opened in the middle of the circular placement platform 102, and the outer wall of the adsorption hole 105 is fixedly connected to a connecting pipe;

[0029] The outer wall of the storage surface where the main assembly 1 is placed is fixedly connected to a vacuum pump, and the end of the connecting pipe is fixedly connected to the input end of the vacuum pump;

[0030] Turn on the vacuum pump and suck the air around the adsorption hole 105 through the connecting pipe to adsorb the ring on the ring placement table 102.

[0031] The adjustment component 2 includes a driving motor 204 symmetrically fixedly connected to the outer wall of the bottom of the annular base 101. The outer wall of the output end of the driving motor 204 is fixedly connected to the driving gear 203, and the outer wall of the driving gear 203 is meshed with the driven gear 202;

[0032] The driving motor 204 provides power to the driving gear 203, which drives the driven gear 202 to rotate, and the driven gear 202 drives the ring placement platform 102 to rotate through the support shaft 201;

[0034] The ring is supported by a ring placement platform 102;

[0035] Working principle: After manually moving the ring until it contacts the inner wall of the limiting plate 104, the ring is placed on the ring placement table 102, and the vacuum pump is turned on to fix the ring through the adsorption hole 105.

The inner wall of the through hole 406 is slidably connected to the limiting ball 407. The outer wall of the end of the push rod 403 has a groove 405.

[0043] The spring 404 rebounds to return the push rod 403 to its original position, causing the limiting ball 407 to extend from the through hole 406 and contact the inner wall of the corresponding hole to limit the main assembly 1;

[0044] Working principle: Place the main assembly 1 on the storage surface, insert the fixing cylinder 401 into the corresponding hole of the storage surface, press the button 402 to drive the push rod 403 to move, so that the limiting ball 407 slides to the groove 405, release the button 402, and the spring 404 rebounds to return the push rod 403 to its original position, so that the limiting ball 407 slides from the groove 405 to the through hole 406 and extends out of the through hole 406 to contact the inner wall of the corresponding hole of the storage surface, thereby limiting the main assembly 1;
