[0023] Embodiment:

[0024] Referring to Figures 1 - 4 , a visual inspection mechanism for ceramic resistors includes a column 1, on which a camera 701 for detection is provided. It further includes: a rotating shaft 2 is rotatably provided on the column 1, and a servo motor for driving the rotating shaft 2 to rotate is fixedly provided on the column 1. Among them, a mounting plate 201 is fixedly provided at one end of the rotating shaft 2 away from the column 1. Two groups of connecting plates 3 are symmetrically provided on the mounting plate 201. At one end of the two groups of connecting plates 3, glass carriers 4 are fixedly provided. The ceramic resistor is placed on the glass carrier 4. The glass carrier 4 is transparent, and the camera 701 can detect it through the glass carrier 4, improving the use effect. And a driving part for driving the clamping of the glass carrier 4 is provided on the mounting plate 201. During use, by placing the disc-shaped ceramic resistor on the glass carrier 4, through the driving part, the two glass carriers 4 can be made to approach each other and clamp the ceramic resistor. At this time, the camera 701 can detect the front of the ceramic resistor. After the front detection is completed, the servo motor drives the rotating shaft 2 to flip 180 degrees. At this time, the back of the ceramic resistor can be detected, increasing the detection range of the ceramic resistor and improving the detection quality; a fixing plate 7 is provided on the column 1 in a lifting manner, and the camera 701 is provided at the bottom of the fixing plate 7. The camera 701 can be fixed to the bottom of the fixing plate 7 by means of screws or buckles, etc. Preferably, it is a buckle, which is convenient for installation and disassembly and improves the use effect.

[0025] Referring to Figure 2, the driving part can use a cylinder or a hydraulic cylinder to drive two connecting plates 3 to approach or move away from each other, so as to clamp the ceramic resistor. Here, we design the driving part as: a bidirectional screw 5. Among them, a guiding groove 202 is opened on the mounting plate 201. The other ends of the two connecting plates 3 are both slidably arranged in the guiding groove 202, and the bidirectional screw 5 is rotatably arranged in the guiding groove 202. Moreover, the two connecting plates 3 are respectively threadedly connected to both ends of the bidirectional screw 5. A second motor 501 for driving the bidirectional screw 5 to rotate is fixedly arranged on the mounting plate 201. When in use, by driving the bidirectional screw 5 to rotate through the second motor 501, the two connecting plates 3 can be driven to approach or move away from each other simultaneously. At this time, the glass carrier 4 can be used to clamp the ceramic resistor. On the one hand, it is convenient to detect the ceramic resistor and prevent the ceramic resistor from moving during the detection process, which affects the detection result. On the other hand, the ceramic resistor can be turned over to facilitate the detection of its two sides and improve the detection range.

[0026] Refer to Figure 2 and Figure 4 , a plurality of air blowing holes 302 are opened on both of the two connecting plates 3. The number of the air blowing holes 302 is two to ten groups. Here, we preferably choose five groups. A flow dividing groove 303 is opened in both of the two connecting plates 3. The plurality of air blowing holes 302 are respectively communicated with the corresponding flow dividing grooves 303. When in use, by supplying air into the flow dividing groove 303, the gas can be ejected from the air blowing holes 302. At this time, the outer wall of the glass carrier 4 can be purged to reduce the dust accumulated on the glass carrier 4 and improve the clarity of the glass carrier 4, thereby reducing the influence on the surface detection of the ceramic resistor.

[0027] Refer to Figure 4 , an air pump or a blower can be used to supply air to the flow dividing groove 303. Here, an installation groove 203 communicated with the guiding groove 202 is opened in the mounting plate 201. An air bag 6 is arranged in the installation groove 203. A push plate 301 is fixedly arranged on one end of the connecting plate 3 extending into the installation groove 203. Both ends of the air bag 6 are respectively fixedly connected with the push plate 301 and the installation groove 203. An air inlet pipe 601 and an air outlet pipe 602 are fixedly arranged on the air bag 6. The air outlet pipe 602 is communicated with the flow dividing groove 303. Moreover, one-way valves are fixedly arranged on both the air inlet pipe 601 and the air outlet pipe 602. When in use, when the two connecting plates 3 clamp the ceramic resistor, the air bag 6 can be extruded through the push plate 301. The gas in the air bag 6 enters the flow dividing groove 303 through the air outlet pipe 602 and then is ejected from the air blowing holes 302. At this time, the outer surface of the glass carrier 4 can be purged. When the detection is over and the two connecting plates 3 move away from each other, the air bag 6 can be pulled to draw air from the outside through the air inlet pipe 601, which is convenient for the next use.

[0028] Refer toFigure 1 and Figure 3 , a chute 101 is provided on the column 1, one end of the fixing plate 7 is slidably arranged in the chute 101, and a first screw rod 102 is rotatably arranged in the chute 101. The fixing plate 7 is threadedly connected with the first screw rod 102, and a first motor 103 for driving the first screw rod 102 to rotate is fixedly arranged on the column 1. During use, by driving the first screw rod 102 to rotate through the first motor 103, the fixing plate 7 can be driven to slide up and down along the chute 101, facilitating the adjustment of the distance between the camera 701 and the ceramic resistor and improving the detection effect.

[0029] Refer to Figure 1 and Figure 3 , an annular lamp holder 702 is arranged on the fixing plate 7, the camera 701 is located inside the lamp holder 702, and a second screw rod 703 is rotatably arranged on the lamp holder 702. The end of the second screw rod 703 away from the lamp holder 702 is threadedly connected with the fixing plate 7. A knob is fixedly arranged at the top of the second screw rod 703, and a guide rod 704 is fixedly arranged on the lamp holder 702. The guide rod 704 is slidably connected with the fixing plate 7. Preferably, two groups of guide rods 704 are provided to ensure the reliable sliding of the lamp holder 702. During use, by driving the second screw rod 703 to rotate through the knob, the lamp holder 702 can be driven to slide up and down, facilitating the adjustment of the light irradiation range on the lamp holder 702 and improving the use effect.
