[0034] Schematic double-sided detection mechanism of the chip

[0035] Reference Figures 1 to 6 , according to a preferred embodiment of the present invention, the double-sided detection mechanism of the chip, it should be noted that the present invention is provided in such as Figure 1On the shown body 10, and the body 10 includes a first conveying device 20, a first support plate 30, and a second support plate 40. The second support plate 40 is located below the first conveying device 20, and the first support plate 30 is located above the first conveying device 20. It should be noted that the double-sided detection mechanism of the chip includes a first detection component 50 and a second detection component 60. The first detection component 50 is arranged on the first support plate 30 and faces the first conveying device 20, and the second detection component 60 is arranged on the second support plate 40 and faces the first conveying device 20.

[0036] It is worth mentioning that the above-mentioned first conveying device 20 conveys the chip 300 for the user. At the same time, the first detection component 50 faces the top surface of the chip, and the second detection component 60 faces the bottom surface of the chip 300. It should be noted that the above-mentioned first conveying device 20 is a conventional chip production line in the prior art and can meet the requirement of conveying the chip. Specifically, the first conveying device 20 can be implemented as two oppositely arranged side plates 21, and a plurality of pulleys and a conveyor belt 22 wound around the plurality of pulleys are provided on each side plate 21. The chip contacts the two conveyor belts 22 and moves synchronously through the movement of the conveyor. It should be noted that, as Figure 3 shown, two guiding plates 200 are further provided on the front side of the first conveying device 20, and a guiding groove is provided on each side of the two guiding plates 200 that are close to each other. In addition, the above-mentioned body further includes a second conveying device 700. The second conveying device 700 is located on the side of the guiding plates 200 away from the first conveying device, and the second conveying device 700 is arranged to be dockable with the two guiding plates. The chip is located on the second conveying device 700. When the second conveying device 700 is docked with the two guiding plates, the chip located on the second conveying device 700 is arranged to be guided to the first conveying device. When the second conveying device 700 drives the chip to operate in the direction close to the first conveying device 20, both sides of the chip 300 are arranged to be matched with the two guiding grooves, and at the same time, the chip also passes through the first detection component 50 and the second detection component 60, and then the detection is completed.

[0037] Among them, the first detection component 50 includes a connecting column 51. One end of the connecting column 51 is fixed to the side of the first support plate 30 away from the first conveying device 20. The structure of the connecting column 51 is as Figure 4As shown. The first detection component 50 further includes a first connecting member 52 and a second connecting member 53. One side of the first connecting member 52 and the second connecting member 53 close to each other has a first mounting groove 502, and the two first mounting grooves 502 together form a first fitting cavity 501. It is worth mentioning that the side of the first connecting member 52 facing away from the second connecting member 53 also has two relatively arranged first connecting holes 503, and the two first connecting holes 503 are also connected to the first mounting groove 502 of the first connecting member 52. Those skilled in the art should understand that the user can cooperate two bolts with the two first connecting holes 503 respectively and thread-connect them to the side of the second connecting member 53 close to the first connecting member 52. That is, by tightening the two bolts, the first connecting member 52 and the second connecting member 53 are moved a predetermined distance toward each other. At this time, the size of the first fitting cavity 501 is reduced, and further, the first connecting member 52 and the second connecting member 53 both limit the connecting column 51.

[0038] Further, the second connecting member 53 also has a connecting end 531. The connecting end 531 is connected to the second connecting member 53 and extends a predetermined distance in a direction away from the first connecting member 52. The first detection component 50 further includes a third connecting member 54. The third connecting member 54 is fixedly connected to the connecting end 531. The first detection component 50 further includes a first camera 55. One side of the first camera 55 is fixedly connected to the connecting end 531. Thus, the position of the first camera 55 is limited by the connecting end 531, and the first camera 55 faces the top surface of the chip on the first conveying device 20. In addition, those skilled in the art should understand that the above-mentioned first camera 55 adjusts the distance between the first camera 55 and the top surface of the chip 300 by loosening and tightening the two bolts.

[0039] Further, the double-sided detection mechanism of the chip further includes a first lighting component 70. The first lighting component 70 is arranged at the bottom of the first support plate 30 and faces the top surface of the chip. The first lighting component 70 includes a first connecting plate 71. The first connecting plate 71 is fixed to the bottom of the first support plate 30, and the first connecting plate 71 also has two relatively arranged connecting portions 711. In addition, the first lighting component 70 further includes a first lighting lamp 72. Two ends of the first lighting lamp 72 are rotatably connected to one side of the two connecting portions 711 close to each other. Specifically, the above-mentioned first lighting lamp 72 can rotate a predetermined angle to adjust the light. In addition, as Figure 4As shown, each of the connecting parts 711 has an arc-shaped positioning groove 71101, and the first lighting lamp 72 further has at least one positioning hole 7201. That is, when the first lighting lamp 72 rotates, the positioning hole 7201 can always be directly opposite to the arc-shaped positioning groove 71101. That is, the user can pass an external screw through the arc-shaped positioning groove 71101 and thread-connect it to the positioning hole 7201, so as to limit the position of the first lighting lamp 72 through at least one external screw.

[0040] In addition, it should be noted that the double-sided detection mechanism of the chip further includes a second detection component 60. The second detection component 60 includes a first fixed block component 61, a second connecting plate 62 and a second camera 63. The first fixed block component 61 is fixed to the bottom of the second support plate 40. It should be noted that the implementation manner of the above-mentioned first fixed block component 61 can be the same as that of the above-mentioned first connecting member 52 and second connecting member 53. That is, the first fixed block component 61 can be implemented as a first fixed block and a second fixed block. Both sides of the first fixed block and the second fixed block close to each other have a second installation groove. At the same time, the two second installation grooves together form a second matching cavity. And the first fixed block can be connected to the second fixed block through two external bolts, so that the second matching cavity is reduced, and then the first fixed block component 61 is limited to the bottom of the second support plate 40. The two ends of the second connecting plate 62 are rotatably connected to both sides of the first fixed block component 61, and the second camera 63 is fixed to the second connecting plate 62. Specifically, when the second connecting plate 62 rotates a predetermined angle, the second camera 63 rotates a predetermined angle synchronously, and the second camera 63 is also directly opposite to the bottom of the chip 300.

[0041] In addition, the double-sided detection mechanism of the chip further includes a support platform 80. The support platform 80 includes at least one support column 81 and a third support plate 82. One end of the support column 81 is fixed to the top of the second support plate 40, and the other end is fixedly connected to the third support plate 82. Both of the above-mentioned guide plates 200 are arranged on the third support plate 82.

[0042] Specifically, the double-sided detection mechanism of the chip further includes a second lighting component 90, which includes a second fixing block component 91, two third connecting plates 92, and a second lighting lamp 93. The second fixing block component 91 is fixed on the support column 81. It is worth mentioning that the implementation manner of the second fixing block component 91 is the same as that of the first fixing block component 61, so it will not be described again. The two third connecting plates 92 are arranged oppositely and spaced apart by a predetermined distance. The sides of the two third connecting plates 92 close to each other are fixedly connected to both sides of the second fixing block component 91, and both ends of the second lighting lamp 93 are rotatably connected to the sides of the two third connecting plates 92 close to each other. Specifically, the connection manner of the second lighting lamp 93 and the third connecting plate 92 can be the same as the connection manner of the connecting portion 711 and the first lighting lamp 72. The second lighting lamp 93 is also directly opposite to the bottom of the chip 300 placed on the first conveying device 20.

[0043] In addition, it should be noted that, as Figure 7As shown, the double-sided detection mechanism of the chip further includes a wire-pulling encoder 400. The wire-pulling encoder 400 is disposed on one side of the first conveying device. The wire-pulling encoder 400 has a retractable rope body. The double-sided detection mechanism of the chip further includes a laterally movable moving block 500. The moving block 500 is spaced a predetermined distance from the wire-pulling encoder 400, and the moving block 500 is also fixedly connected to the rope body. In addition, the moving block 500 is connected to a driving component 600, and the driving component 600 is arranged to be able to drive the moving block 500 to move laterally. Wherein, when the second conveying device 700 guides the chip to the first conveying device, the driving component 600 drives the moving block 500 to move a predetermined distance in the direction close to the wire-pulling encoder 400, so as to realize the counting of the wire-pulling encoder 400. Thus, when the moving block 500 moves to a predetermined position, the first camera and the second camera operate synchronously. That is, after the first shooting is completed, the driving component 600 will reset. In addition, it should be noted that the above-mentioned third support plate 82 is also provided with a trigger (not shown in the figure). The trigger is located between the two guide plates 200. That is, when the chip passes through the trigger, the driving component 600 starts to operate to drive the moving block 500 to move in the direction close to the first conveying device 20, so as to determine that the moving distance of each chip is predetermined in this way, so as to ensure that the first camera and the second camera can photograph the chip. Specifically, the above-mentioned moving block 500 is installed on the guide rail of the machine body, so as to realize the lateral movement of the moving block 500 in a predetermined direction. The driving component 600 is located above the moving block 500 and is fixedly connected to the top of the moving block 500 to control the lateral movement of the moving block 500. That is, those skilled in the art should understand that the above-mentioned driving component 600 can be a linear motor or a cylinder, and the present invention preferably uses a cylinder.

[0044] In summary, the double-sided detection mechanism of the chip based on the embodiment of the present application is clarified, which provides advantages such as a simple structure, the ability to synchronously detect both sides of the chip, and high practicability for the double-sided detection mechanism of the chip.

[0045] It is worth mentioning that in the embodiment of the present application, the double-sided detection mechanism of the chip has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economy. At the same time, for manufacturers, the double-sided detection mechanism of the chip provided by the present application is easy to produce and has a low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
