[0067] The appearance inspection system and the guide mechanism thereof according to the embodiments of the present application are described below. However, it can be easily understood that the embodiments of the present application provide many suitable novel concepts and can be implemented in a wide variety of specific contexts. The specific embodiments shown are merely used for illustration to use the present application in a specific method, and are not intended to limit the scope of the present application.
[0068] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present application, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
[0069] The foregoing and other technical contents, features and effects of the present application will be apparent from the following detailed description of a preferred embodiment, with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only the directions of the accompanying drawings. Therefore, the directional terms used in the embodiments are used for illustration, not for limiting the present application.
[0070] First, refer to Figure 1 wherein Figure 1 represents a schematic view of an appearance inspection system 100 according to an embodiment of the present application.
[0071] As Figure 1As shown, the appearance detection system 100 of the embodiment of the present application is mainly used for appearance detection of electronic components E with a hexahedral shape, such as resistors or capacitors, and mainly comprises a vibrating disc 10, a conveying device 20, a circular carrier 30, a guide 40, and a detection device 50 (for example, a CCD).
[0072] Specifically, the input end and the output end of the conveying device 20 are connected to the vibrating disc 10 and the carrier 30 respectively, and the guide 40 and the detection device 50 are arranged on one side of the carrier 30 and adjacent to the carrier 30, wherein the vibrating disc 10 can rotate and make the electronic components E arranged thereon sequentially move along the feeding direction A1 (as shown in Figure 1 ) in the vibrating manner. Figure 1 The electronic components E are then moved along the first groove V1 of the conveying device 20 (as shown by the feeding direction A2 in
[0073] It should be particularly noted that a magnetic component M (for example, a magnet) is arranged on one side of the conveying device 20, wherein the magnetic component M can act a magnetic force on the electronic components E to force the laminated layers of each electronic component E to be adjusted to be consistent, thereby being beneficial to the subsequent accurate appearance detection of the electronic components E on the carrier 30 by the detection device 50.
[0074] Then, please refer to Figure 2 , Figure 3 , wherein Figure 2 represents a partial enlarged view of the conveying device 20 and the magnetic component M in Figure 1 , Figure 3 represents a schematic view of the electronic components E falling from the rear section V12 of the first groove V1 to the front section V21 of the second groove V2.
[0075] As shown in Figure 2 , Figure 3 , when the electronic components E move to the tail end of the first groove V1 of the conveying device 20, the electronic components E will fall one by one into the second groove V2 on the base 21 of the conveying device 20 due to the influence of the slope structure of the first groove V1 bottom side gradually decreasing depth towards the feeding direction A2.
[0076] As shown in Figure 2As shown, the aforementioned first groove V1 and second groove V2 constitute a guide mechanism V on the conveying device 20, wherein the first groove V1 has a first central shaft X1, the second groove V2 has a second central shaft X2, the aforementioned first groove V1 and second groove V2 are adjacent to each other, and the first central shaft X1 and the second central shaft X2 are parallel to each other and separated by a distance.
[0077] In this embodiment, the bottom side of the aforementioned first groove V1 has an arc surface, and the aforementioned second groove V2 has a V-shaped cross-section, and from... Figure 3 As can be seen, the position of the second groove V2 is slightly lower than that of the first groove V1. In this way, when the electronic component E moves to the tail end of the first groove V1 of the conveying device 20, the electronic component E can be affected by the slope structure at the tail end of the first groove V1 and fall into the second groove V2 one by one.
[0078] Next, the electronic component E slides from the conveyor 20 onto the stage 30 and is guided to a predetermined position via the guide 40. Then, the electronic component E can rotate with the stage 30 (e.g., ...). Figure 1 (As indicated by the middle arrow A3) and passes through the detection device 50 one by one, so that the detection device 50 can acquire the image of the electronic component E for complete appearance inspection.
[0079] from Figure 2 As can be seen, the first groove V1 in this embodiment has a front section V11 and a rear section V12 that are connected to each other, wherein the first central axis X1 of the first groove V1 passes through the front section V11 and the rear section V12, and an arc surface is formed on the bottom side of the front section V11 and the rear section V12 of the first groove V1.
[0080] Furthermore, the second groove V2 in this embodiment has a front section V21 and a rear section V22 that are connected to each other, wherein the second central axis X2 of the second groove V2 passes through the front section V21 and the rear section V22, and both the front section V21 and the rear section V22 of the second groove V2 have a V-shaped cross section.
[0081] It should be noted that a slope VS is formed on the bottom side of the rear section V12 of the aforementioned first groove V1, which gradually becomes shallower towards the feeding direction A2. Figure 2 When viewed along a side perpendicular to the aforementioned feeding direction A2 towards D, the rear section V12 (slope VS) of the aforementioned first groove V1 at least partially overlaps with the front section V21 of the second groove V2.
[0082] As previously mentioned, when the electronic components E slide from the front section V11 of the first groove V1 of the conveying device 20 to the rear section V12 along the feeding direction A2, the aforementioned electronic components E will be affected by the slope VS of the bottom side of the rear section V12 gradually becoming shallower along the feeding direction A2 and will thus fall over into the second groove V2 on the conveying device 20 (as shown by the arrow D1 in Figure 3 ).
[0083] On the other hand, it can be seen from Figure 2 that the magnetic assembly M is arranged at the intersection of the front section V11 and the rear section V12 of the first groove V1. In other words, when viewed along the aforementioned lateral direction D, the magnetic assembly M will at least partially overlap the relative positions of the front section V11, the rear section V12 (slope VS) of the first groove V1 and the front section V21 of the second groove V2.
[0084] In one embodiment, when viewed along the aforementioned lateral direction D, the magnetic assembly M can also only overlap the relative position of the rear section V12 (slope VS) of the first groove V1 and not overlap the relative position of the front section V11 of the first groove V1, and thus the present application is not limited to the embodiments disclosed herein.
[0085] Please also refer to Figure 4 , Figure 5 , wherein Figure 4 represents a schematic view of the electronic components E sliding to the rear section V22 of the second groove V2, Figure 5 represents a schematic view of the electronic components E sliding onto the carrier 30.
[0086] As shown in Figure 4 , when the electronic components E slide from the front section V21 to the rear section V22 of the second groove V2, the electronic components E will gradually turn straight in the direction of the arrow D2 along with the change in the groove shape of the bottom side of the rear section V22, thereby gradually changing the laminate structure of the electronic components E to be parallel to the vertical direction.
[0087] Subsequently, the aforementioned electronic components E will successively slide from the rear section V22 of the second groove V2 to the bearing surface 31 of the carrier 30 (as shown in Figure 5 ), and the laminate structure EL inside all the electronic components E will be perpendicular to the aforementioned bearing surface 31, so as to facilitate subsequent accurate appearance detection of the electronic components E on the bearing surface 31 by the detection device 50.
[0088] Please refer to Figure 6 , wherein Figure 6 represents a schematic view of an appearance detection system 200 according to another embodiment of the present application.
[0089] As shown in Figure 6 , the appearance detection system 200 according to the present embodiment is similar to the appearance detection system 100 according to the first embodiment of the present application. Figure 1The main difference between the appearance inspection system 100 in the prior art and the appearance inspection system 200 in the present embodiment is that the conveying device 20 in the appearance inspection system 200 in the present embodiment is additionally provided with a third groove V3, and a first camera C1 and a first air blowing unit B1 are additionally arranged on one side of the second groove V2, and a second camera C2 and a second air blowing unit B2 are also arranged on one side of the second groove V2.
[0090] Specifically, when the electronic component E moves along the first groove V1, passes the magnetic component M and falls into the second groove V2, the first camera C1 can be used to take a picture of the electronic component E in the second groove V2 and confirm whether the lamination direction of the electronic component E is correct, and if the lamination direction of the electronic component E is incorrect, the first air blowing unit B1 can be used to blow the electronic component E to another third groove V3 with a V-shaped cross section (a flipping procedure). The electronic component E continues to move along the third groove V3 and converges back to the second groove V2, and then the second camera C2 can be used to take another picture of the electronic component E in the second groove V2 and confirm whether the lamination direction of the electronic component E is correct, and if the lamination direction of the electronic component E is correct, the electronic component E can continue to move along the second groove V2, so as to successfully slide onto the bearing surface 31 of the loading platform 30.
[0091] On the contrary, if the second camera C2 detects that the lamination direction of the electronic component E is still incorrect, the second air blowing unit B2 can be used to blow the electronic component E to the recycling area 60 (a kicking procedure), and then the conveying mechanism of the recycling area 60 can be used to send the electronic component E back to the vibrating disc 10 (as indicated by an arrow A4 in the prior art), or send the electronic component E back to the conveying device 20 to repeat the aforementioned feeding procedure. Figure 6
[0092] In the present embodiment, the first groove V1, the second groove V2 and the third groove V3 constitute a guide mechanism V on the conveying device 20, and by arranging the first and second cameras C1, C2 and the first and second air blowing units B1, B2, the lamination direction of the electronic component E can be detected and confirmed before the electronic component E moves to the loading platform 30, and the electronic component E that fails to pass the detection can be directly removed from the guide mechanism V, so as to ensure that the lamination direction of the electronic component E that moves to the loading platform 30 is correct, thereby greatly improving the accuracy of the appearance inspection and the yield of the product.
[0093] Please refer to Figure 7 , wherein Figure 7 represents a schematic diagram of the appearance inspection system 300 in another embodiment of the present application.
[0094] As shown in Figure 7 , the appearance inspection system 300 in the present embodiment is similar to the appearance inspection system 100 in the prior art. Figure 1 The main difference between the appearance inspection system 100 in the prior art and the appearance inspection system 300 of the present embodiment is that the guide mechanism V (the first groove V1 and the second groove V2) of the appearance inspection system 300 is arranged on the base 11 of the vibrating disc 10, and the first center axis X1 of the first groove V1 and the second center axis X2 of the second groove V2 are both in the shape of a circular arc and extend along the feeding direction A1, and the magnetic assembly M is arranged on one side of the vibrating disc 10.
[0095] On the other hand, a fourth groove V4 and a fifth groove V5 are arranged side by side on the base 21 of the conveying device 20, wherein the fourth groove V4 and the fifth groove V5 both have a V-shaped cross section, and a camera C and a blowing unit B are arranged on one side of the fourth groove V4.
[0096] Specifically, the electronic components E move along the feeding direction A1 in the first groove V1 on the conveying device 20 and pass through the magnetic assembly M, so that the stacking directions of the electronic components E are adjusted to be consistent, and then the electronic components E are affected by the slope structure of the bottom side of the first groove V1 gradually becoming shallower along the feeding direction A1 and fall into the second groove V2, and then the electronic components E enter the fourth groove V4 on the conveying device 20.
[0097] When the electronic components E enter the fourth groove V4, the camera C can be used to take a picture and confirm whether the stacking direction of the electronic components E is correct. If the stacking direction of the electronic components E is incorrect, the blowing unit B can be used to blow the electronic components E into the fifth groove V5 (a flipping procedure) and make the electronic components E flip to the correct stacking direction, and then the electronic components E can continue to move along the fifth groove V5 and converge back into the fourth groove V4, so that the electronic components E can be smoothly slid onto the bearing surface 31 of the loading platform 30.
[0098] In the present embodiment, by arranging the guide mechanism V (the first groove V1 and the second groove V2) in the shape of a circular arc on the base 11 of the vibrating disc 10, the stacking directions of most of the electronic components E can be adjusted to be consistent in advance, and then the camera C and the blowing unit B can be used to detect and confirm whether the stacking direction is correct, so that the stacking directions of the electronic components E moving to the loading platform 30 are all correct, thereby improving the accuracy of appearance inspection and the yield of products.
