Abstract
Description
Technical Field
[0001] This utility model relates to the field of cam mechanism technology, and in particular to a cam mechanism for a 48PIN transformer AOI visual inspection equipment. Background Technology
[0002] In the 48PIN transformer AOI visual inspection equipment, the cam mechanism is a mechanical transmission mechanism consisting of a cam, a follower, and a frame. The cam is a component with a curved profile or a groove. Through the rotational motion of the cam, the follower is driven to perform reciprocating motion or other expected motion patterns, thus playing a key role in mechanical motion control in the inspection equipment.
[0003] In some existing AOI visual inspection equipment, the transmission mechanism used to move the transformer has insufficient positioning accuracy. For example, when using a simple linear motor or cylinder drive, it is difficult to ensure that the transformer can accurately stop at the specified position during the inspection process due to the influence of load changes and mechanical wear, which leads to deviations in the inspection results. Utility Model Content
[0004] The purpose of this invention is to provide a cam mechanism for an AOI visual inspection device for a 48-pin transformer. By using this device, the above-mentioned problems can be solved.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cam mechanism for an AOI visual inspection device for a 48PIN transformer, including a frame, a connecting plate at the front end of the top of the frame, X-axis moving guide rails on both sides of the top of the connecting plate, an X-axis moving plate fixed on the slider of the X-axis moving guide rail, Y-axis moving guide rails at both ends of the top of the X-axis moving plate, a Y-axis moving plate fixed on the slider of the Y-axis moving guide rail, a shift fork block fixed on the right side of the Y-axis moving plate, a material trough fixed on the right side of the top of the frame, the shift fork block placed on the top of the material trough, and a drive mechanism at the rear end of the top of the frame.
[0006] Preferably, the drive mechanism includes a Y-direction moving cam disposed at the rear end of the top of the frame, an X-direction moving cam fixed at the bottom of the Y-direction moving cam, a servo motor disposed at the rear end of the bottom of the frame, a reducer disposed at the top of the servo motor, a coupling disposed at the top of the reducer, the top of the coupling protruding from the top of the frame and connected to the shaft at the bottom of the X-direction moving cam, and a slotted sensor disposed at the rear end of the coupling.
[0007] Preferably, a cam rod is provided on the left side of the Y-direction moving cam, and a Y-axis cam follower is provided at the front end of the top of the cam rod. The Y-axis cam follower is located on the left side of the Y-direction moving plate.
[0008] Preferably, an X-axis cam follower is provided at the front end of the X-direction moving cam, and a push rod is fixed at the top of the X-axis cam follower. The push rod is fixed to the left rear end of the X-direction moving plate.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. The cam mechanism of the 48PIN transformer AOI visual inspection equipment provided by this utility model completes the actions of approaching, pushing, retracting and resetting in sequence through the continuous cyclic movement of the shift fork block, thereby realizing the efficient transportation of the frequency converter. This cyclic operation mode is closely coordinated with the inspection process of the AOI visual inspection equipment. Within one inspection cycle, the shift fork block can quickly transport the frequency converter to the inspection position, and then remove it in time after the inspection is completed, so as to prepare for the inspection of the next frequency converter and improve the overall working efficiency of the equipment.
[0011] 2. The cam mechanism of the 48PIN transformer AOI visual inspection equipment provided by this utility model has good coordination between the actions of various components. The X-axis moving guide rail and the Y-axis moving guide rail provide stable guidance for the X-axis moving plate and the Y-axis moving plate, respectively, so that the movement of the shift fork block in different directions can be carried out in an orderly manner. Moreover, the precise control of movement in different directions by the cam mechanism reduces the conflict and delay between actions. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0016] Combination Figure 1 This utility model discloses a cam mechanism for an AOI visual inspection device for a 48-pin transformer, comprising a frame 1. A connecting plate 552 is provided at the front end of the top of the frame 1. X-axis moving guide rails 55 are provided on both sides of the top of the connecting plate 552. An X-axis moving plate 551 is fixed on the slider of the X-axis moving guide rail 55. Y-axis moving guide rails 52 are provided at both ends of the top of the X-axis moving plate 551. A Y-axis moving plate 521 is fixed on the slider of the Y-axis moving guide rail 52. A shift fork block 54 is fixed on the right side of the Y-axis moving plate 521. A material trough 541 is fixed on the right side of the top of the frame 1. The shift fork block 54 is placed on top of the material trough 541. A drive mechanism is provided at the rear end of the top of the frame 1.
[0017] The drive mechanism includes a Y-direction moving cam 49 located at the top rear end of the frame 1, an X-direction moving cam 48 fixed at the bottom of the Y-direction moving cam 49, a servo motor 44 located at the bottom rear end of the frame 1, a reducer 45 located at the top of the servo motor 44, a coupling 46 located at the top of the reducer 45, the top of the coupling 46 protruding from the top of the frame 1 and connected to the shaft at the bottom of the X-direction moving cam 48, a slotted sensor 47 located at the rear end of the coupling 46, a cam rod 51 located on the left side of the Y-direction moving cam 49, a Y-axis cam follower 53 located at the front end of the top of the cam rod 51, the Y-axis cam follower 53 located on the left side of the Y-direction moving plate 521, an X-axis cam follower 50 located at the front end of the X-direction moving cam 48, a push rod 501 fixed at the top of the X-axis cam follower 50, and the push rod 501 fixed to the left rear end of the X-direction moving plate 551.
[0018] Working principle:
[0019] The servo motor 44 is started to drive the X-direction moving cam 48 and the Y-direction moving cam 49 to rotate. The Y-direction moving cam 49 first contacts the rear end of the cam rod 51, pushing the rear end of the cam rod 51 to tilt it. The front end of the cam rod 51 drives the Y-axis cam follower 53 to push the Y-direction moving plate 521, causing the shift fork block 54 to move towards the position of the frequency converter in the feed trough 541. The slider at the bottom of the Y-direction moving plate 521 follows it and moves on the Y-direction moving guide rail 52. When the groove of the shift fork block 54 is engaged with the outside of the frequency converter, the slider at the bottom of the Y-direction moving plate 521 locks, keeping the shift fork block 54 in the position inserted outside the frequency converter. At this time, the moving direction of the shift fork block 54 towards the frequency converter is the +y direction. Figure 1 As indicated by the middle arrow;
[0020] Subsequently, the X-direction moving cam 48 rotates, pushing the X-axis cam follower 50 to move the X-direction moving plate 551, connected by the push rod 501, forward. The slider at the bottom of the X-direction moving plate 551 follows it, moving on the X-axis moving guide rail 55. When the X-direction moving cam 48 stops pushing the X-axis cam follower 50, the slider at the bottom of the X-direction moving plate 551 locks, fixing the position of the X-direction moving plate 551. The movement of the X-direction moving plate 551 drives the shift fork block 54 forward, thereby pushing the inverter in the groove of the shift fork block 54 forward. At this time, the movement direction of the shift fork block 54 is the +x direction, such as... Figure 1 As indicated by the middle arrow;
[0021] Then, using the slider at the bottom of the Y-direction moving plate 521 in conjunction with the Y-direction moving guide rail 52, the Y-direction moving plate 521 and the shift fork block 54 are moved toward a position away from the inverter. The direction of movement is the -y direction. Figure 1 As indicated by the Chinese symbol;
[0022] After the shift fork block 54 moves away from the inverter, the slider at the bottom of the X-direction moving plate 551, in conjunction with the X-axis moving guide rail 55, drives the Y-direction moving plate 521 and the shift fork block 54 to move backward and reset. Their movement direction is the -x direction. Figure 1 As indicated by the Chinese symbol;
[0023] Repeat the above operation. The moving directions of the shift fork block 54 are as follows: first, it moves closer to the inverter in the +y direction, then moves to push the inverter in the +x direction, then moves back away from the inverter in the -y direction, and finally moves to reset in the -x direction to push the inverter for the next time. By repeating this cycle, the shift fork block 54 can move back and forth to deliver the inverter.
