Description

Technical Field

[0001] This utility model belongs to the field of product appearance inspection technology, and specifically relates to an MLCC appearance defect detection device. Background Technology

[0002] CN 212328949 U, entitled "An Appearance Defect Detection Device for Inductor Components", comprises: a support assembly, a carrying and conveying mechanism, a feeding mechanism, a detection mechanism, and a distributing mechanism disposed on the support assembly; the carrying and conveying mechanism includes a turntable and a drive motor connected to the turntable, the turntable being used to carry the inductor components, and the drive motor being used to drive the turntable to rotate the inductor components; the feeding mechanism, detection mechanism, and distributing mechanism are sequentially located around the turntable to feed, detect, and distribute the inductor components. The feeding mechanism includes a vibratory feeder, in which the inductor components are placed and conveyed to the turntable by vibration and orientation. The support assembly includes a support plate and a support frame, the carrying and conveying mechanism, the detection mechanism, and the distributing mechanism are all disposed on the support plate, and the vibratory feeder is disposed on the support frame. The number of detection mechanisms is six, and the six detection mechanisms are respectively located on the top, bottom, outer side, inner side, front side, and rear side of the turntable for detecting appearance defects on the six sides of the inductor components. The inspection mechanism includes an inspection bracket and a visual inspection camera. The inspection bracket is mounted on the support assembly, and the visual inspection camera is mounted on the inspection bracket. When the inductor rotates on the turntable and passes the visual inspection camera, the visual inspection camera detects appearance defects in the inductor. The inspection mechanism also includes a light source device, which provides a light source for the visual inspection camera to detect the inductor. The sorting mechanism includes at least two sorting components, which are used for sorting qualified products and defective products, respectively. The sorting mechanism also includes three sorting components, which are used for sorting qualified products, defective products, and untested products, respectively. Each sorting component includes an air blowing device and a receiving box that cooperates with the air blowing device. When the inductor rotates on the turntable and passes the air blowing device, the air blowing device blows the inductor into the receiving box to complete the sorting. Its shortcomings are: the failure rate of this type of inductor appearance defect detection equipment is relatively high (the guide channel of the feed guide mechanism in this type of inductor appearance defect detection equipment is an inclined channel. The inductor that slides down from the vibratory plate through the inclined channel onto the turntable has a relatively high speed. The inductor with a relatively high speed is more likely to slide away from the detection area of ​​the turntable. When the inductor is partially or completely stuck in the non-detection area of ​​the turntable, the inductor will become an undetected product). Utility Model Content

[0003] Design objective: To design an MLCC appearance defect detection device that not only has a relatively lower failure rate but also high detection efficiency.

[0004] Design scheme: To achieve the above design objectives.

[0005] 1. The upper end of the base is provided with a feeding mechanism, a carrying and conveying mechanism, a first detection mechanism, a second detection mechanism, a third detection mechanism, a fourth detection mechanism, a fifth detection mechanism, a sixth detection mechanism, and a dispensing mechanism. The first detection mechanism, the second detection mechanism, the third detection mechanism, the fourth detection mechanism, the fifth detection mechanism, the sixth detection mechanism, and the dispensing mechanism are arranged around the rotating detection disk in the carrying and conveying mechanism. A feeding guide mechanism is provided between the vibrating disk and the rotating detection disk in the feeding mechanism. A guide channel is provided on the transmission plate in the feeding guide mechanism, with one end of the guide channel being an upper channel opening and the other end being a lower channel opening. The guide channel is composed of a communicating inclined channel section and a horizontal channel section. The outer port of the inclined channel section is the upper channel opening, and the outer port of the horizontal channel section is the lower channel opening. The height of the upper channel opening is higher than the height of the lower channel opening. The discharge port of the vibrating disk is connected to the upper channel opening, and the lower channel opening is located on the rotating detection disk. This design is one of the technical features of this utility model. The purpose of this design is twofold: First, the feed guiding mechanism has a guide channel on the transmission plate, with one end of the guide channel being the upper channel opening and the other end being the lower channel opening. The guide channel consists of interconnected inclined and horizontal channel sections. The outer port of the inclined channel section is the upper channel opening, and the outer port of the horizontal channel section is the lower channel opening. The height of the upper channel opening is higher than that of the lower channel opening. The discharge port of the vibratory feeder is connected to the upper channel opening, and the lower channel opening is located on the rotating detection plate. The inclined and horizontal channel sections allow MLCC products sliding down from the vibratory feeder onto the rotating detection plate at a relatively low speed, making it less likely for the MLCC products to slip out of the detection area of ​​the rotating detection plate, thereby reducing the untested rate of MLCC products. Second, this MLCC appearance defect detection device achieves fully automatic feeding, detection, and sorting of MLCC products, ensuring the detection efficiency of the device, which can reach up to 12,000 pcs / min in actual use.

[0006] 2. The design of having a limiting block mounting base at the upper end of the base, with a limiting block on the upper surface of the mounting base, and the limiting block located outside the lower channel opening, is the second technical feature of this utility model. The purpose of this design is that the limiting block, located outside the lower channel opening, prevents the MLCC product from sliding out of the rotating testing disk.

[0007] Technical Solution: An MLCC appearance defect inspection device includes a base, a feeding mechanism, a carrying and conveying mechanism, a first inspection mechanism, a second inspection mechanism, a third inspection mechanism, a fourth inspection mechanism, a fifth inspection mechanism, a sixth inspection mechanism, and a dispensing mechanism. The upper end of the base is provided with the feeding mechanism, the carrying and conveying mechanism, the first inspection mechanism, the second inspection mechanism, the third inspection mechanism, the fourth inspection mechanism, the fifth inspection mechanism, the sixth inspection mechanism, and the dispensing mechanism.

[0017] Example 1: Refer to Appendix Figures 1-8 A device for detecting appearance defects in MLCCs includes a base 1, a feeding mechanism 2, a carrying and conveying mechanism 3, a first detection mechanism 4, a second detection mechanism 5, a third detection mechanism 6, a fourth detection mechanism 7, a fifth detection mechanism 8, a sixth detection mechanism 9, and a dispensing mechanism 10. The upper end of the base 1 is provided with the feeding mechanism 2, the carrying and conveying mechanism 3, the first detection mechanism 4, the second detection mechanism 5, the third detection mechanism 6, the fourth detection mechanism 7, the fifth detection mechanism 8, the sixth detection mechanism 9, and the dispensing mechanism 10. The first detection mechanism 4, the second detection mechanism 5, the third detection mechanism 6, the fourth detection mechanism 7, the fifth detection mechanism 8, the sixth detection mechanism 9, and the dispensing mechanism 10 are arranged on a rotating detection disk 31 within the carrying and conveying mechanism 3. On the periphery of the feeding mechanism 2, a feeding guide mechanism 11 is provided between the vibrating plate 21 and the rotating detection plate 31. The transmission plate 111 in the feeding guide mechanism 11 is provided with a guide channel 112, one end of which is an upper channel opening 113 and the other end is a lower channel opening 114. The guide channel 112 is composed of an inclined channel section 115 and a horizontal channel section 116 that are in communication. The outer port of the inclined channel section 115 is the upper channel opening 113, and the outer port of the horizontal channel section 116 is the lower channel opening 114. The height of the upper channel opening 113 is higher than the height of the lower channel opening 114. The discharge port of the vibrating plate 21 is connected to the upper channel opening 113, and the lower channel opening 114 is located on the rotating detection plate 31.

[0018] The upper end of the base 1 is provided with a limiting block mounting seat 12, and the upper end surface of the limiting block mounting seat 12 is provided with a limiting block 13. The limiting block 13 is located outside the lower channel opening 114. The rotating inspection disk 31 is made of transparent glass, which has a certain hardness while ensuring transparency. The first inspection mechanism 4, the second inspection mechanism 5, the third inspection mechanism 6, the fourth inspection mechanism 7, the fifth inspection mechanism 8, and the sixth inspection mechanism 9 are respectively used to inspect one corresponding surface of the MLCC product. That is, the MLCC product is placed on the rotating inspection disk 13 for mobile all-round appearance defect inspection, which saves the steps of changing the position and angle of the MLCC product, ensuring the accuracy of the inspection while reducing the difficulty of the inspection. MLCC products located in the vibratory feeder 21 are conveyed sequentially through the discharge port of the vibratory feeder 21, the upper channel port 113 of the infeed guide mechanism 11, and the lower channel port 114 of the infeed guide mechanism 11 before being transported to the rotary testing plate 31. The MLCC products on the rotary testing plate 31 are then driven by the rotary testing plate 31 to sequentially pass through the first testing mechanism 4, the second testing mechanism 5, the third testing mechanism 6, the fourth testing mechanism 7, the fifth testing mechanism 8, the sixth testing mechanism 9, and the sorting mechanism 10. The sorting robotic arm 101 in the sorting mechanism 10 is used to classify and collect the tested MLCC products. A controller is also included. The signal output terminals of the first testing mechanism 4, the second testing mechanism 5, the third testing mechanism 6, the fourth testing mechanism 7, the fifth testing mechanism 8, and the sixth testing mechanism 9 are respectively connected to the signal input terminal of the controller via data cables. The signal output terminal of the controller is connected to the signal input terminal of the sorting mechanism 10 via a data cable.

[0019] MLCC products are aligned and fed using a vibratory feeder. The aligned MLCCs then flow into a rotating inspection disc via a feeding guide mechanism. Driven by the rotating inspection disc, the MLCCs sequentially pass through the first, second, third, fourth, fifth, and sixth inspection mechanisms, and a sorting mechanism to complete top, bottom, left, right, front, and back appearance inspections. Afterward, the rotating inspection disc carries the MLCCs to the sorting mechanism 10 for classification and collection. Specifically, the first inspection mechanism inspects the corresponding surfaces of the MLCCs and uploads the inspection data to the controller; the second, third, fourth, fifth, and sixth inspection mechanisms also upload the data; and the sixth inspection mechanism... After the corresponding sides of the product are inspected, the inspection data is uploaded to the controller. The controller can analyze and judge the inspection data of the same MLCC product uploaded by the first, second, third, fourth, fifth, and sixth inspection agencies. Based on the judgment result, the controller controls the sorting mechanism to sort the MLCC products. For example, when the controller determines that at least one side of the MLCC product is defective based on the inspection data, the controller will control the corresponding sorting robot arm to pick up the MLCC product and place it in the defective product area when the MLCC product rotates to the sorting mechanism. When the controller determines that the MLCC product is not defective based on the inspection data, the controller will control the corresponding sorting robot arm to pick up the MLCC product and place it in the good product area when the MLCC product rotates to the sorting mechanism. When the controller does not receive inspection data for at least one side of the MLCC product, the controller will control the corresponding sorting robot arm to pick up the MLCC product and place it in the uninspected product area when the MLCC product rotates to the sorting mechanism, thus realizing classified collection. The controller's ability to analyze and judge the testing data uploaded by the first, second, third, fourth, fifth, and sixth testing institutions is existing technology and will not be further elaborated here. After analyzing and judging the testing data, the controller can control the sorting robotic arm in the material distribution mechanism to grab MLCC products to the corresponding storage area according to the judgment result. This is also existing technology and will not be further elaborated here.

[0020] A device for detecting MLCC appearance defects is applicable to MLCC series products and has good applicability; in addition, the maximum detection speed of the device can reach 12000pcs / min.

Any combination, addition, or modification that does not exceed the design concept of this utility model shall fall within the protection scope of this utility model.
