Detailed implementation mode

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. 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 shall fall within the protection scope of the present invention.

[0035] Embodiment 1: Please refer to Figures 1 to 4 , a patch component appearance detection device, including a device frame 1. The upper end of the device frame 1 is fixedly installed with an operation table 2 through bolts. The upper end of the operation table 2 is fixedly installed with a stabilizing ring 201 through bolts. On the left side of the stabilizing ring 201, there is an eyepiece 4 for the operator to observe the outer surface of the patch. The left side of the stabilizing ring 201 is fixedly connected with a lens barrel 41. The end of the lens barrel 41 far from the stabilizing ring 201 is fixedly connected with the eyepiece 4. Specifically, a plurality of lenses are installed inside the lens barrel 41, so that the pattern inside the stabilizing ring 201 can be reflected to the eyepiece 4 under the refraction of the lenses. And an ultraviolet lamp is fixedly installed near the lens barrel 41 of the stabilizing ring 201, which is convenient for observing the outer surface of the component more prominently. The inner end of the stabilizing ring 201 is rotatably installed with a rotating frame 204. A plurality of stabilizing cylinders 301 are rotatably installed on the outer surface of the rotating frame 204. An adsorption device for picking up the patch components is arranged inside each of the stabilizing cylinders 301. The front end of the stabilizing ring 201 is detachably installed with a partition plate 202, and the partition plate 202 is used to isolate foreign impurities from entering the stabilizing ring 201. The rear end of the stabilizing ring 201 is fixedly installed with a servo motor 203. The output shaft of the servo motor 203 is fixedly connected with the rotating frame 204, and the servo motor 203 can accurately control the rotating frame 204 to rotate at any angle and maintain the current angle state. The upper end of the device frame 1 is fixedly installed with a controller 3 through bolts. The controller 3 is electrically connected to the servo motor 203 through a wire;

[0036] As Figure 4As shown in the figure, a spraying device for spraying fluorescent agent on the outer surface of the chip component is provided at the right end of the inner side of the stabilizing ring 201. And a paint wiping cloth 206 for erasing the fluorescent agent on the outer surface of the chip component is detachably installed at the upper end of the inner side of the stabilizing ring 201. The controller 3 is used to control the start and stop of the servo motor 203, as well as the rotation angle and rotation speed, and can also control the working states of the adsorption device and the spraying device. The paint wiping cloth 206 can be detached at any time and replaced regularly to avoid the decline of wiping efficiency caused by long-term use. When the outer surface of the chip component is fully coated with fluorescent agent and is completely wiped clean by the paint wiping cloth 206, it indicates that there are no defects on the appearance of the current chip component. In the case of the next chip component, the fluorescent agent will seep into the gaps of the defects and cannot be erased by the paint wiping cloth 206. It should be noted that the fluorescent agent is a special marking type (such as TRACERSpray), which can form a stable film on the outer surface of the chip component. The ingredients contain alcohol and can dry quickly after spraying, and then can be easily erased by the paint wiping cloth 206;

[0037] As Figure 3 As shown in the figure, a rectangular hole is opened at the upper end of the operating table 2, and a defective product box 103 for placing defective components is detachably installed at the lower end of the operating table 2 through bolts. The upper end of the defective product box 103 corresponds to the rectangular hole. A receiving box 102 for placing qualified components is detachably connected to the upper end of the operating table 2 through a buckle. A distributing plate 107 is rotatably installed at the inner end of the receiving box 102. The distributing plate 107 corresponds to the defective product box 103. A handle is rotatably installed at the front end of the receiving box 102. The handle is fixedly connected to the distributing plate 107. By default, the distributing plate 107 completely covers the upper part of the defective product box 103 and is in an inclined state, so that the qualified chip components can fall into the receiving box 102 along the slope. The handle is used to control the rotation of the distributing plate 107. As the distributing plate 107 rotates, the upper part of the defective product box 103 is exposed, and then the unqualified chip components will fall into the defective product box 103;

[0038] A stabilizing plate 108 is fixedly installed at the upper end of the operating table 2, and a lifter 106 is fixedly installed at the upper end of the operating table 2. The telescopic end of the lifter 106 is fixedly installed with a lifting plate 104. Stabilizing wheels are rotatably installed at the left and right ends of the lifting plate 104 and the stabilizing plate 108. The outer surfaces of the stabilizing wheels on the mutually remote sides of the lifting plate 104 and the stabilizing plate 108 are tightly sleeved by a conveyor belt 101. And the conveyor belt 101 has a certain elasticity. When the conveyor belt 101 transports the chip components to the lifting plate 104, specifically, an infrared sensor is arranged at the inner end of the lifting plate 104. The infrared sensor is electrically connected to the lifter 106 through a wire. When the infrared sensor senses that the chip components reach above, then the infrared sensor sends an electrical signal to the lifter 106. Then the lifter 106 pushes the lifting plate 104 upward. More specifically, a conveyor motor 105 is fixedly installed at the upper end of the operating table 2 through bolts. The output shaft of the conveyor motor 105 is fixedly connected to any one of the stabilizing wheels.

[0039] Example 2: Please refer to Figure 4 、 5 、6. A chip component appearance detection device. Based on Example 1, the adsorption device includes a limiting abutting ring 302. The limiting abutting ring 302 is fixedly installed at the right end of the stabilizing cylinder 301. A glue ball 303 for picking up chip components is fixedly installed at the inner end of the limiting abutting ring 302. One end of the glue ball 303 away from the stabilizing cylinder 301 is in the shape of a suction cup. When the chip component is attached thereto, the air inside the suction cup is squeezed out. Under the action of the atmospheric pressure, the chip component is firmly and tightly attached to the outer surface of the glue ball 303. An electric push rod 305 is fixedly installed at the inner end of the stabilizing cylinder 301. A sealing plate 313 is fixedly installed at the end of the glue ball 303 close to the electric push rod 305. A central rod 306 is fixedly installed on the outer surface of the electric push rod 305. A through hole is opened at the center of the sealing plate 313. One end of the central rod 306 away from the electric push rod 305 passes through the through hole and is fixedly connected to the right end inside the glue ball 303. Specifically, a sealing rubber ring is fixedly installed at the through hole at the center of the sealing plate 313. The sealing rubber ring is in close fit with the outer surface of the central rod 306 for improving airtightness. During the movement of the central rod 306, the shape of the suction cup on the right side of the glue ball 303 is changed, so as to adsorb chip components of different sizes, enabling the device to adapt to chips of various signals. More specifically, the glue ball 303 for adsorbing chip components enables the components to contact the outer surface of the paint wiping cloth 206 during the rotation of the rotating frame 204;

[0040] Please refer to Figure 7 、 8, the right end of the sealing plate 313 is fixedly installed with an absorption cylinder 311. The absorption cylinder 311 is located above the central rod 306, and a driving rod 310 passes through the inner end of the absorption cylinder 311. A sleeve 309 is slidably installed on the outer surface of the central rod 306. A rectangular block is fixedly installed at the inner end of the sleeve 309. A rectangular groove is formed on the outer surface of the central rod 306. The rectangular block is located in the rectangular groove, so as to avoid the phenomenon of self-rotation when the sleeve 309 slides left and right on the outer surface of the central rod 306. One end of the driving rod 310 away from the absorption cylinder 311 is fixedly connected to the outer surface of the sleeve 309. A connecting ring 314 is fixedly installed on the outer surface of the central rod 306 through bolts. The connecting ring 314 is located on the left side of the sealing plate 313. One end of the driving rod 310 away from the sleeve 309 is fixedly connected to the connecting ring 314. Specifically, a piston 312 is fixedly installed on the outer surface of the driving rod 310. The piston 312 is located inside the absorption cylinder 311. More specifically, a sealing rubber ring is fixedly installed on the outer surface of the piston 312. The sealing rubber ring is in close fit with the inner wall of the absorption cylinder 311 to increase airtightness;

[0041] When the piston 312 moves to the left, the air inside the rubber ball 303 is pumped into the absorption cylinder 311, so that the volume of the rubber ball 303 becomes smaller while the rubber ball 303 becomes smaller at the suction cup. When adsorbing the patch component, it can avoid other parts of the rubber ball 303 contacting the component and causing the component to fall due to uneven force. Multiple movable rods 308 are rotatably installed on the outer surface of the sleeve 309. The movable rods 308 are arranged in a ring shape. The connections between the movable rods 308 and the sleeve 309 are all clamped by torsion springs. Multiple contraction grooves 307 are formed on the inner wall of the rubber ball 303. The contraction grooves 307 correspond to the movable rods 308. One end of the movable rod 308 away from the sleeve 309 is slidably installed in the contraction groove 307. Specifically, the inside of the contraction groove 307 is rhomboid, and the end of the movable rod 308 away from the sleeve 309 is adapted to the inner shape of the contraction groove 307. Then when the sleeve 309 moves to the left, the inside of the rubber ball 303 is supported by multiple regularly arranged movable rods 308, so that the shape of the rubber ball 303 when deflated is controlled when the rubber ball 303 is evacuated;

[0042] Example 3: Please refer to Figure 9 , 10, 11. A surface mount component appearance detection device. Based on Example 1, the spraying device includes an annular cover 205. The annular cover 205 is fixedly installed at the right inner end of the stabilizing ring 201. A nozzle 207 for spraying fluorescent agent is fixedly installed at the inner end of the annular cover 205. A paint cylinder 210 is fixedly installed at the right inner end of the stabilizing ring 201. The paint cylinder 210 is located on the right side of the annular cover 205. A pump body 211 is fixedly installed on the outer surface of the annular cover 205. And the output end of the paint cylinder 210 and the input end of the pump body 211 are fixedly connected by an input pipe 209. The output end of the pump body 211 and the input end of the nozzle 207 are fixedly connected by an output pipe 208;

[0043] As Figure 10 , 11 , a driving motor 212 is fixedly installed at the inner end of the stabilizing ring 201. A transmission rod 214 is arranged below the driving motor 212. The transmission rod 214 is rotatably connected to the stabilizing ring 201. And stabilizing wheels are fixedly installed on the output end of the driving motor 212 and the outer surface of the transmission rod 214. A toothed belt 213 is tensioned and sleeved on the outer surface of the stabilizing wheels. Specifically, a toothed ring 304 is fixedly installed on the outer surface of the stabilizing cylinder 301. And the toothed ring 304 meshes with the toothed belt 213. An impeller 215 is rotatably installed at the inner end of the pump body 211. The impeller 215 is fixedly connected to the transmission rod 214.

[0044] The working principle of the present invention is:

[0045] During use, before use, the surface mount components to be detected are placed one by one above the feeding belt 101. Subsequently, the output end of the conveying motor 105 drives the feeding belt 101 above. At this time, the output shaft of the servo motor 203 drives the rotating frame 204 to rotate, and rotates any one of the rubber balls 303 above the lifting plate 104. At this time, the telescopic end of the electric push rod 305 drives the central rod 306 to move to change the shape of the suction cup for adapting to the current model of the surface mount component. Subsequently, the lifter 106 pushes the lifting plate 104 upward so that the surface mount component to be detected fits against one side of the suction cup of the rubber ball 303. Subsequently, the lifter 106 restores the lifting plate 104 to the initial state;

[0046] Subsequently, the output end of the servo motor 203 drives the rotating frame 204 to rotate, and rotates the component to correspond to the nozzle 207. At the same time, the toothed ring 304 on the outer surface of the stabilizing cylinder 301 meshes with the toothed belt 213. Subsequently, the drive motor 212 drives the toothed belt 213 to rotate. At this time, the toothed ring 304 drives the stabilizing cylinder 301 to rotate in the meshed state. At this time, the component is in a rotating state. At the same time, the transmission rod 214 drives the impeller 215 inside the pump body 211 to rotate. During the rotation of the impeller 215, the fluorescent agent inside the pigment cylinder 210 is pumped to the nozzle 207. Subsequently, the fluorescent agent is sprayed out from the nozzle 207 and then adheres to the outer surface of the component. Subsequently, the rotating frame 204 continues to rotate. During the rotation, the surface mount component contacts the outer surface of the paint wiping cloth 206, and the fluorescent agent adhering to the outer surface of the component is wiped off during the rotation. If the component is a defective product, the fluorescent agent will adhere to the gap at the defective part and cannot be wiped off. Subsequently, the component moves to the observation position of the lens barrel 41. Under the irradiation of the ultraviolet lamp, the fluorescent agent becomes more prominent. Subsequently, the operator observes the state of the fluorescent agent adhering to the outer surface of the component through the eyepiece 4;

[0047] After observation, the rotating frame 204 continues to rotate. At this time, the component is located above the sorting plate 107. Subsequently, the telescopic end of the electric push rod 305 drives the central rod 306 to move, so that the central rod 306 pulls the rubber ball 303 to continuously contract. Finally, the surface mount will contact the limiting collar 302. Under the interaction of forces, the surface mount is separated from the adsorption of the rubber ball 303 and falls into the defective product box 103 or the receiving box 102.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
