[0035] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] Please refer to Figures 1 - 9 , this application provides an optical inspection machine for electronic products, including a bracket 1. A turnover and steering unit 2 for turning over and steering the electronic product is installed on the bracket 1. The turnover and steering unit 2 includes a support leg 21 for support, and a rotating rod rotatably installed on the support leg 21. A support seat 24 is fixedly connected to the rotating rod, and the rotating rod is driven by a servo motor 22. A steering mechanism 23 for adjusting the side orientation of the electronic product is installed on the support leg 21, and the servo motor 22 is fixedly connected to the support leg 21. The steering mechanism 23 includes a first fixed rod 231 fixedly connected to the support leg 21 for fixing and supporting an internal gear ring 232. One end of the first fixed rod 231 away from the support leg 21 is fixedly connected to the internal gear ring 232. It should be noted that the internal gear ring 232 is concentric with the rotating rod. A transmission gear 233 is meshed and connected to the inner side of the internal gear ring 232. A transmission shaft 234 for transmission is fixedly connected to the transmission gear 233. A second fixed rod 235 is fixedly connected to the lower end of the support seat 24. A fixed sleeve 236 is fixedly connected to the lower end of the second fixed rod 235. The transmission shaft 234 is rotatably connected to the inside of the fixed sleeve 236. Among them, the fixed sleeve 236 provides support for the transmission shaft 234. One end of the transmission shaft 234 away from the transmission gear 233 is connected to a rotating shaft 238 through a steering gear set 237. The rotating shaft 238 is rotatably connected to the support seat 24. Among them, the steering gear set 237 is composed of two bevel gears for steering. A placement plate 25 is fixedly connected to the upper end of the rotating shaft 238. A first chute 251 is fixedly connected to one end of the placement plate 25 close to the second conveyor belt assembly 7 for supporting the bottom end of the electronic product during the turnover process of the electronic product.

[0038] In this embodiment, a top plate 8 is installed above the bracket 1. Two sets of inspection mechanisms 9 for inspecting the electronic product are arranged below the top plate 8. The turnover and steering unit 2 is arranged in the middle area between the two sets of inspection mechanisms 9. The inspection mechanism 9 includes an adjustable telescopic rod 91 for adjusting the height of the optical inspection component 93. An installation seat 92 is arranged below the adjustable telescopic rod 91. An optical inspection component 93 is installed on the lower wall of the installation seat 92. A plurality of optical inspection components 93 are installed, which can simultaneously inspect three surfaces of the electronic product.

[0039] In this embodiment, a first fixing frame 3 is provided on the bracket 1, and a first conveyor belt assembly 4 is installed on the first fixing frame 3. The first conveyor belt assembly 4 is an existing product for conveying electronic products, and the first conveyor belt assembly 4 is arranged below one of the detection mechanisms 9. A second fixing frame 5 is also installed on the bracket 1, and a second conveyor belt assembly 7 is installed on the second fixing frame 5. A plurality of conveyor belts are provided in the second conveyor belt assembly 7, and there are gaps in the middle to provide an installation space for the buffer mechanism 6.

[0040] Specifically, when the support base 24 drives the electronic product to rotate, and the specific rotation angle can be greater than 90 degrees so that the electronic product can fall face down. As the support base 24 rotates, it can drive the second fixed rod 235 and the fixed sleeve column 236 to revolve. The fixed sleeve column 236 drives the inner transmission shaft 234 to revolve. One end of the transmission shaft 234 is connected with a transmission gear 233 that meshes with the internal gear ring 232, thereby driving the transmission shaft 234 to rotate. It should be noted that the tooth density on the internal gear ring 232 and the transmission gear 233 needs to be specifically set according to the revolution angle of the rotating rod, and it is ensured that it can rotate 90 degrees. The transmission shaft 234 drives the rotating shaft 238 to rotate through the rotation of the steering gear set 237, and the rotating shaft 2,38 drives the placement plate 25 to rotate 90 degrees. Thus, while turning the electronic product face down, it can be turned 90 degrees. Compared with the existing method of turning face down first and then turning, it not only saves space but also improves work efficiency.

[0041] Embodiment Two:

[0042] On the basis of Embodiment One, a buffer mechanism 6 for preventing the electronic product from directly and quickly falling on the second conveyor belt assembly 7 during the face-turning process is installed on the bracket 1. The buffer mechanism 6 includes a connecting frame 61. It should be noted that the connecting frame 61 plays a role in supporting and fixing the second air pump 62. The lower end of the connecting frame 61 is fixedly connected with a second air pump 62. A sealing pipe 63 is arranged on the second air pump 62. A connecting rod 64 is arranged inside the sealing pipe 63. The lower end of the connecting rod 64 is provided with a piston 69 that is used in cooperation with the sealing pipe 63 and is sealed. The upper end of the connecting rod 64 is fixedly connected with a ball seat 66. The ball seat 66 is connected with a buffer pad 67 through a rolling ball. A counterweight 68 is fixedly connected to the buffer pad 67. The counterweight 68 plays a role in adding weight, making the orientation of the buffer pad 67 tend to the electronic product on the face-turning and steering unit 2. Here, it should be noted that a limiting block is arranged on the sphere inside the ball seat 66, and a corresponding limiting groove is arranged inside the ball seat 66, so that the sphere inside the ball seat 66 cannot roll randomly, that is, the buffer pad 67 can only rotate from the orientation towards the face-turning and steering unit 2 to the orientation towards the second conveyor belt assembly 7.

[0043] In this embodiment, a switch for controlling the blowing and suction of the second air pump 62 is provided on the bracket 1, and a push block for pushing the switch is provided on the support base 24.

[0044] Specifically, before the flip-turning unit 2 flips the electronic product and it does not fall onto the second conveyor belt assembly 7, the upper half of the electronic product first falls onto the buffer pad 67. At the same time, when the support base 24 rotates to the end point, it can contact the switch provided on the bracket 1 to cause the second air pump 62 to slowly pump air, thereby causing the piston 69 to slowly move downward. When the push block separates from the switch on the bracket 1, the second air pump 62 can inject gas into the sealing tube 63 again, causing the piston 69 to rise. The piston 69 drives the connecting rod 64 to move downward, and the connecting rod 64 drives the ball seat 66 and the buffer pad 67 thereon to move downward. Under the action of the pressure of the electronic product, the buffer pad 67 rotates, which can facilitate the better fitting of the buffer pad 67 with the electronic product, increasing the contact area. As the piston 69 descends until it touches the bottom, at this time the buffer pad 67 is flush with the second conveyor belt assembly 7. Under the conveying action of the second conveyor belt assembly 7, the electronic product is sent to the next detection area. Thus, during the process of flipping and turning the electronic product, buffering is provided to reduce damage to the electronic product during the optical detection process, changing the way that in the existing flipping process, the electronic product directly falls, which is likely to cause the electronic product to be bumped and damaged.

[0045] Embodiment Three:

[0046] Based on Embodiment Two, a clamping mechanism 26 for clamping the electronic product during the flipping process is installed above the placement plate 25. The clamping mechanism 26 includes a first air pump 261 fixedly connected to the top plate 8, and the first air pump 261 is connected to an airbag 263 through a delivery pipe 262.

[0047] Specifically, by blowing and sucking air through the first air pump 261, the airbag 263 clamps the electronic product, avoiding the problem that the electronic product accidentally falls off the placement plate 25 during the flip-turning process and causing damage to the electronic product.

[0048] Embodiment Four:

[0049] On the basis of Embodiment 3, a distance adjusting mechanism 27 for adjusting the distance of the clamping mechanism 26 is installed on the placement plate 25. The distance adjusting mechanism 27 includes two movable plates 271 symmetrically arranged on the placement plate 25 for fixing the airbag 263. A first chute 251 for the two movable plates 271 to slide correspondingly is provided on the placement plate 25. A fixed collar 274 is fixedly connected to each movable plate 271. A connecting shell 275 is provided on the fixed collar 274. A second chute 278 is arranged inside the connecting shell 275. Two symmetrically arranged U-shaped pressing blocks 276 are slidably arranged inside the second chute 278. A second return spring 277 for resetting is arranged between the two U-shaped pressing blocks 276. Slots 254 arranged in a linear array and matching with the U-shaped pressing blocks 276 are formed on the placement plate 25.

[0050] In this embodiment, the distance adjusting mechanism 27 further includes a fixed block 272 fixedly connected to the lower end of the placement plate 25. A first spring 273 is installed between the fixed block 272 and the movable plate 271, which always has a thrust on the movable plate 271, facilitating quick opening after the movable plate 271 is released, providing sufficient spacing to allow electronic products to be placed between the two airbags 263.

[0051] Specifically, before detecting electronic products of the same batch, first place the electronic products between two uninflated airbags 263. Then, by pressing the upper end of the U-shaped pressing block 276 and squeezing the second return spring 277, the lower end of the U-shaped pressing block 276 is withdrawn from the corresponding slot 254. Next, push the two movable plates 271 towards the electronic products, just getting closer, so that the airbags 263 can clamp the electronic products after inflation. Release the U-shaped pressing block 276, and under the action of the elastic force of the second return spring 277, the lower end of the U-shaped pressing block 276 is pushed into the nearest slot 254 again. Thus, by adjusting the distance adjusting mechanism 27, the distance between the two airbags 263 in the clamping mechanism 26 can be adjusted, which can be applicable to electronic products of different sizes, improving the applicability of the device and expanding the applicable range of the device.

[0052] In summary, first place the electronic products on the first conveyor belt assembly 4. Through the transmission of the first conveyor belt assembly 4 and the optical detection of three surfaces of the electronic products by the first group of detection mechanisms 9. Then, the first conveyor belt assembly 4 conveys the electronic products to the placement plate 25, and they are clamped by inflation through the clamping mechanism 26 to prevent accidental dropping of the electronic products during the turning process. The placement plate 25 can turn over and rotate the electronic products, that is, when the electronic products fall onto the second conveyor belt assembly 7, the other three surfaces of the electronic products can be detected by the second group of detection mechanisms 9, and they can be buffered by the buffer mechanism 6 during the process of falling onto the second conveyor belt assembly 7, reducing the risk of the electronic products being knocked.

[0053] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
