[0051] In this embodiment, the roller 131 can be made of metal or plastic, or a plastic sleeve can be placed on the outer surface of the metal core shaft, and the outermost layer of the roller 131 can be covered with a rubber sleeve 134 to increase the friction coefficient with the capacitor to avoid slipping and protect the capacitor. The top diameter of the gear 132 is less than or equal to the outer diameter of the rubber sleeve 134 to avoid blocking the camera of the capacitor end.

[0052] In this embodiment, the gear 132 at the end of the roller assembly 130 is meshed with the outer teeth 171 of the roller assembly driving wheel 170. Figure 3 , 6 The outer teeth 171 of the roller assembly driving wheel 170 drive the six rollers 131 to rotate in the same direction through the gear 132.

[0055] In this embodiment, the roller 155 can be made of metal or plastic and covered with a rubber sleeve (not shown in the figure) to increase the friction coefficient with the capacitor, avoid slipping, and protect the capacitor.

[0056] like Fig.10As shown, the gear meshing assembly includes a flange 163, a gear bracket 160, a first meshing gear 161 and a second meshing gear 162, the flange 163 is connected to the shaft end flange 159, the first meshing gear 161 and the second meshing gear 162 are both set on the gear bracket 160 through a rotating shaft, the first meshing gear 161 and the second meshing gear 162 are meshed, the gear bracket 160 is set on the flange 163, the first meshing gear 161 is meshed with the internal meshing teeth 156, and the second meshing gear 162 is meshed with the internal teeth 172 of the roller assembly driving wheel 170.

[0057] In this embodiment, the first meshing gear 161 and the second meshing gear 162 are meshed, and the meshing directions of the first meshing gear 161 and the second meshing gear 162 are opposite. Figure 8 and 10 The first meshing gear 161 meshes with the internal meshing teeth 156, and the second meshing gear 162 meshes with the internal teeth 172 of the roller assembly driving wheel 170, see the attached Figure 3 , so that the roller 155 and the roller assembly driving wheel 170 rotate in opposite directions.

[0058] The driving gear 153 at the shaft end of the second motor 151 drives the roller 155 to rotate through the external meshing gear 154, and the internal meshing gear 156 drives the second meshing gear 162 through the first meshing gear 161 on the gear bracket 160. Figure 8 , and then drives the roller assembly driving wheel 170 to rotate, and the outer teeth 171 of the roller assembly driving wheel 170 drives all the rollers 131 in the roller assemblies 130 to rotate in the same direction through the gear 132. Because the roller 155 and the roller assembly driving wheel 170 rotate in opposite directions, the roller 155 and all the rollers 131 rotate in the same direction.

[0059] like Figure 3 As shown, the roller drive motor assembly 150 and the gear meshing assembly are both extended into the roller shaft assembly 130, and a receiving groove 149 for placing the capacitor 001 is formed between each two adjacent roller shafts 131 and the roller 155 in the roller shaft assembly 130.

[0060] The working process of the electrolytic capacitor appearance inspection equipment in this embodiment is as follows:

[0061] The capacitor 001 is fed into the capacitor guide groove 303, and the capacitor 001 enters the capacitor feeding guide groove 102. The capacitor 001 in the capacitor feeding guide groove 102 automatically rolls into the receiving groove 149 formed by the roller 155 and the adjacent roller shaft 131, and rotates with the roller 155 and the roller shaft 131. See the attached Figure 4 Due to the depth and width of the receiving groove 149, only one capacitor can be inserted into the receiving groove 149 at a time. Figure 4 .

[0062] Before the capacitor 001 enters the receiving groove 149, the right end camera 210 and the left end camera 220 arranged at both ends of the rotating host 100 respectively take pictures of the two ends of the capacitor 001 and perform inspection and judgment.

[0063] The driving gear 153 at the shaft end of the second motor 151 drives the roller 155 to rotate through the external meshing gear 154, and the internal meshing gear 156 drives the second meshing gear 162 through the first meshing gear 161 on the gear bracket 160. Figure 8 , and then drives the roller assembly driving wheel 170 to rotate, and the outer teeth 171 of the roller assembly driving wheel 170 drive the rollers 131 in all the roller assemblies 130 to rotate in the same direction through the gear 132. Because the roller 155 and the roller assembly driving wheel 170 rotate in opposite directions, the roller 155 and all the rollers 131 rotate in the same direction, and drive the capacitor 001 to rotate continuously.

[0064] The first motor 111 rotates intermittently. The first motor 111 drives the turntable assembly 120 and the roller assembly 130 to rotate 60 degrees counterclockwise as a whole and then stops (taking 6 rollers 131 as an example), and brings the capacitor 001 to the middle position of the rotating host 100. At this time, the peripheral camera 230 above the rotating host 100 takes pictures quickly as the capacitor 001 rotates one circle, and takes several pictures (4 or more) of the outer circle of the capacitor 001 and makes a judgment.

[0065] After the shooting is completed, the first motor 111 drives the turntable assembly 120 to rotate 60 degrees counterclockwise and then stops. After the photo comparison and analysis, the capacitor rotates with the turntable 120 to the corresponding position of the defective blow-out air pipe 114. If the capacitor is judged to be genuine, the air pipe does not blow air and continues to the next station; if the capacitor is judged to be defective, at this time, the control valve is opened, and high-pressure air enters the defective blow-out air pipe 114 to blow the defective capacitor containing groove 149 to the right.

[0066] The first motor 111 then drives the turntable assembly 120 to rotate 60 degrees counterclockwise as a whole and then stops. At this time, the genuine capacitor falls down under the action of gravity and rolls out along the qualified product discharge guide plate 103.

[0067] Anything not specifically described in the specification of the present invention is prior art or can be implemented by existing technology. It should be understood that for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should fall within the scope of protection of the claims attached to the present invention.
