Description

Technical Field

[0001] The present invention relates to the field of electrolytic capacitor inspection, and in particular to a fully automatic appearance inspection and box packaging device for electrolytic capacitors. Background Art

[0002] Electrolytic capacitors are a type of capacitor. Electrolytic capacitors have a large capacitance per unit volume, which can be dozens or even hundreds of times larger than other types of capacitors. In addition, their rated capacity can be very large and they are cost-effective. Therefore, they are widely used in various electronic products.

[0003] The reliability of electrolytic capacitors often has a significant impact on the reliability of electronic products. Therefore, after production, electrolytic capacitors often require a visual inspection to reduce the probability of defective products and ensure the reliability of subsequent use. On the other hand, electrolytic capacitors are usually placed in boxes after the visual inspection to facilitate the storage and transportation of large quantities of electrolytic capacitors.

[0004] Currently, the appearance inspection and box placement of electrolytic capacitors are usually done manually. However, manual operation is slow, the inspection and box placement efficiency is low, a large number of workers are required, and the labor cost is high. In addition, workers are prone to visual fatigue due to long working hours, which can easily lead to omissions or misjudgments, resulting in the leakage of defective electrolytic capacitors. The outflow of defective products poses great quality risks and hidden dangers. Summary of the Invention

[0052] The second lifting mechanism 76 includes a lifting motor 761, a screw 762, a nut 763, a pressure block seat 764, and a fixed seat 765.

The second guide block 743 is sleeved onto the second guide post 742.

[0054] The feeding mechanism 6 includes a feeding turntable 61, a feeding straight rail 62 and a feeding transfer device 63. The feeding straight rail 62 is installed on the feeding platform, and one end of the feeding straight rail 62 is connected to the feeding turntable 61, and the other end of the feeding straight rail 62 is connected to the feeding transfer device 63.

[0055] When the present invention is in use, the electrolytic capacitor to be inspected can be placed in the feed turntable 61 of the feed mechanism 6, and the feed turntable 61 can push the electrolytic capacitors to be inspected one by one into the feed straight rail 62, and the electrolytic capacitors passing through the feed straight rail 62 will eventually be pushed to the feed transfer device 63, and the feed transfer device 63 can push the electrolytic capacitor into the transfer clamp 33 of the first transfer disc 3.

[0056] The transfer disc precision divider 31 can drive the first turntable 32 to rotate, and the transfer clamp 32 can move accordingly. When the transfer clamp 32 holding the electrolytic capacitor moves to the head appearance inspection mechanism 11, the first camera 111 can photograph the head of the electrolytic capacitor on the transfer clamp 32, and judge whether its head appearance inspection is qualified by manual or software algorithm; when the transfer clamp 32 moves to the tail protrusion inspection mechanism 12, the second camera 121 can photograph the tail aluminum shell position of the electrolytic capacitor on the clamp arm 32, and judge whether its tail protrusion inspection is qualified by manual or software algorithm; when the transfer clamp 32 moves to the tail appearance inspection mechanism 13, the third camera 131 can photograph the tail of the electrolytic capacitor on the transfer clamp 32, and judge whether its tail appearance inspection is qualified by manual or software algorithm; when the transfer clamp 32 moves to the head tilt inspection mechanism 14, the fourth camera 131 can photograph the tail of the electrolytic capacitor on the transfer clamp 32, and judge whether its tail appearance inspection is qualified by manual or software algorithm; The head 141 can photograph the head of the electrolytic capacitor on the transfer clamp 32, and determine whether the head tilt inspection is qualified through manual or software algorithms; when the transfer clamp 32 moves to the polarity deviation inspection and tail tilt inspection mechanism 16, the sixth camera 161 can photograph the negative pole mark and the guide pin root position on the head of the electrolytic capacitor on the transfer clamp 32, and the seventh camera 171 can photograph the tail plane of the electrolytic capacitor on the transfer clamp 32, so as to determine whether the guide pin is within the negative pole mark range and mark the negative pole direction through manual or software algorithms, and at the same time check whether the tail tilt inspection is qualified. When the transfer clamp 32 moves to the polarity reversal inspection mechanism 15, the fifth camera 151 can photograph the guide pin of the electrolytic capacitor on the transfer clamp 32, and determine whether the short guide pin direction is consistent with the negative pole mark direction of the previous workstation through manual or software algorithms to determine whether the polarity reversal inspection is qualified.

[0057] The electrolytic capacitors that fail the above inspection will be moved to the first defective discharge mechanism 34 along with the transfer clamp 32. At this time, the first discharge cylinder 342 will drive the clamp opening pin 343 to trigger the clamp opening bearing 331 on the transfer clamp 32, so that the transfer clamp 32 is loosened, and the electrolytic capacitor originally clamped by the transfer clamp 32 will fall into the first slide 341.

[0058] The electrolytic capacitor that has passed the above inspection will be moved to the translation mechanism 5 along with the transfer clamp 32. At this time, the suction nozzle 51 on the translation mechanism 5 can adsorb the electrolytic capacitor on the transfer clamp 32. Then, the rocker arm in the rocker arm part 54 can drive the slider mechanism 52 to move, and the suction nozzle 51 follows, so that the electrolytic capacitor leaves the transfer clamp 32 and is moved to the suction cup 43 of the second transfer disc 4. After that, the suction cup 43 can adsorb the above electrolytic capacitor.

[0059] The transfer disc motor 41 can drive the second turntable 42 to rotate, and the suction cup 43 installed on the second turntable 42 also moves accordingly. When the suction cup 43 with the electrolytic capacitor adsorbed on it moves to the mixing inspection mechanism 2, the eighth camera 21 can clearly capture the outline of the electrolytic capacitor body on the suction cup 43 and the characters on it, and judge whether the mixing inspection is qualified through manual or software algorithms.

[0060] In addition, it is also possible to determine whether the electrolytic capacitor needs to be rotated based on the polarity deviation check and the negative pole identification direction obtained by the tail lift check mechanism 16. If rotation is required, the cylinder 47 can be started so that the cylinder 47 drives the slide to approach the rotating wheel 431 of the suction cup 43 that adsorbs the electrolytic capacitor that needs to be rotated, and the rotating stepper motor 44 can drive the rubber wheel 45 to rotate. After the rubber wheel 45 contacts the rotating wheel 431, the rotating wheel 431 can rotate to realize the rotation of the suction cup 43, so that the electrolytic capacitor adsorbed by the suction cup 43 also rotates.

[0061] The electrolytic capacitor that fails the mixing inspection will move with the suction cup 43 to the second defective discharge mechanism 49, and the second discharge cylinder 491 can push the unqualified electrolytic capacitor from the suction cup 43 to the second slide 492.

[0062] The qualified electrolytic capacitors will be moved along with the suction cup 43 to the feeding and arranging mechanism 720. The first feeding cylinder 791 on the feeding and arranging mechanism 720 will then drive the shifting block 793 to move. The shifting block 793 will shift the qualified electrolytic capacitors on the suction cup 43 into the material channel 794. The second feeding cylinder 792 will then deliver the electrolytic capacitors to the arranging box 71. The partition box 72 can be pre-placed with multiple partitions, and under the pressure of the pressing roller 79, the partitions are tightly pressed together. When a row of electrolytic capacitors can be placed in the material box 71, the horizontal cylinder 741 can be started, so that the horizontal cylinder 741 drives the mounting plate 733 to move toward the partition box 72. During the movement of the mounting plate 733, the second guide column 742 connected to the mounting plate 733 can also move with it, and under the restriction of the second guide block 743, the movement accuracy of the mounting plate 733 is ensured, and the partition suction cup seat 732 connected to the mounting plate 733 moves with it, and the partition suction cup 75 also moves with it. Finally, the partition suction cup 75 can pass through the groove 721 to stick to the partition placed in the partition box 72 and adsorb it.

[0063] Then start the lifting cylinder 731 again, and the lifting cylinder 731 drives the suction cup seat 732 to rise, and the partition suction cup 75 installed on the suction cup seat 732 also rises, so that the partition adsorbed by the partition suction cup 75 can be pulled out from the partition box 72. In addition, in the process of the lifting cylinder 731 driving the partition suction cup seat 732 to move, the first guide block 735 connected to the partition suction cup seat 732 can move along the first guide column 734, thereby guiding the movement of the partition suction cup seat 732 to ensure its movement reliability. If there are partitions that are lifted up as the partition adsorbed by the partition suction cup 75 moves, these partitions will be blocked by the block 710, thereby ensuring that only one partition is removed from the partition box 72.

[0064] When the partition adsorbed by the partition suction cup 75 is completely separated from the partition box 72, the horizontal cylinder 741 can be started to drive the mounting plate 733 to move away from the partition box 72, and the partition suction cup seat 732 and the partition suction cup 75 also move with it. When the partition adsorbed by the partition suction cup 75 reaches above the position where the partition needs to be set in the swing box 71, the lifting cylinder 731 is started, so that the lifting cylinder 731 moves the partition adsorbed by the partition suction cup 75 to the swing box 71.

[0065] Then, the motor 761 is started, which drives the screw rod 762 to rotate, thereby moving the nut 763 downward, and the pressure block seat 764 connected to the nut 763 moves accordingly, and the pressure block 77 connected to the pressure block seat 764 moves accordingly, so that the pressure block 77 can contact the partition adsorbed by the partition suction cup 75, and press the partition off the suction cup 75, thereby placing the partition into the swing box 71, completing the placement of the partition. After that, all components are reset, and the next partition can be placed in the swing box 71 at any time.

[0066] Therefore, the fully automatic appearance inspection and box-swinging packaging equipment for electrolytic capacitors of the present invention can complete the appearance inspection and box-swinging packaging of electrolytic capacitors, has a high degree of automation and work efficiency, can greatly save manpower, and has strong market competitiveness.

[0067] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
