[0037] This application proposes a visual inspection system for lead-acid battery terminal posts. The visual inspection system of this application is connected to an external PLC system to achieve automatic system control. The PLC system is a conventional setting in existing automation equipment, and this application will not elaborate on it too much. The details are as follows:

[0038] For reference Figure 1-2 , The test paper inspection system of this application mainly consists of a material taking robot 1, a detection device 2, and a discharging conveyor line 3, so as to achieve full-automatic inspection, improve work efficiency, and ensure product quality. Among them,

[0039] For reference Figure 1-2 , The material taking robot 1 is an existing industrial automation robot used to place the test products on the inspection station. It is a mature existing technology and this application will not elaborate on it too much.

[0040] For reference Figure 3 , The detection device 2 mainly consists of a bearing platform 21, a working station part 22, a detection component 23, and a waste collection component 24. The bearing platform 21 is arranged on the front side of the material taking robot 1 to play a role in overall supporting the detection device 2; the working station part 22 is arranged on the bearing platform 21 to receive the test products transferred by the material taking robot 1; the detection component 23 is detachably arranged on the bearing platform 21 and corresponds to the working station part 22, and is used to detect the lead sleeve terminal post of the lead-acid battery received on the working station part 22; the waste collection component 24 is arranged on the bearing platform 21 to collect the waste products that fail the inspection.

[0041] Specifically:

[0042] For reference Figure 3 , The bearing platform 21 includes a square frame 211, support legs 212, and a support plate 213. The square frame 211 is arranged on the top of the support legs 212, and its inner bottom wall horizontally bears the working station part 22 and the detection component 23; the support plate 213 is arranged on the lower side of the middle of the support legs 212, and the height of the waste collection component 24 is adaptively arranged in the gap between the support plate 213 and the square frame 211.

[0043] For reference Figure 4, the station part 22 includes a U-shaped bracket 221, a driving cylinder 222, a driving belt 223 and a station shaft 224. The U-shaped bracket 221 is installed on the lower surface of the square frame 211. The driving cylinder 222 is arranged on the lower side of the U-shaped bracket 221. Thus, there is a moving gap between the output end of the driving cylinder 222 and the lower surface of the square frame 211. The driving belt 223 is arranged in the gap between the two. The driving belt 223 is connected to the output end of the driving cylinder 222 through a toothed shaft. The other side of the driving belt 223 is engaged with the bottom of the station shaft 224. The middle part of the station shaft 224 is rotatably connected to the bottom of the square frame 211. Therefore, when the driving cylinder 222 starts to work, the driving belt 223 drives the station shaft 224 to rotate. And due to the connection between the middle part of the station shaft 224 and the square frame 211, it plays a positioning effect and can only rotate. The top of the station shaft 224 is exposed in the square frame 211. Thus, when rotating, it promotes the rotation of the station shaft 224 to achieve a comprehensive inspection.

[0044] At the same time, there are multiple station shafts 224. In order to drive multiple station shafts 224 by one driving cylinder 222, a ruler belt 225 is added between two adjacent station shafts 224 for connection. Thus, when the driving cylinder 222 drives, the driving belt 223 drives one station shaft 224 to rotate. When one station shaft 224 rotates, the connection of multiple ruler belts 225 realizes the effect of multiple station shafts 224 rotating simultaneously.

[0045] For reference Figure 3 And Figure 5 , the detection component 23 includes a bottom plate 231, an L-shaped plate 232 and a 3D vision sensor 233. The bottom plate 231 is detachably installed on the inner bottom wall of the square frame 211. The bottom plate 231 serves as the bottom support and can directly disconnect the connection between the L-shaped plate 232 and the 3D vision sensor 233 and the carrier 21, reducing the need to disassemble from the carrier 21 multiple times during maintenance. Thus, it effectively reduces the looseness that occurs after long-term use. The L-shaped plate 232 is detachably installed on the upper surface of the bottom plate 231. Due to the L-shaped design, after installation, the vertical installation area is increased on one side (the surface connected to the carrier 21 is horizontal), which raises the installation height of the 3D vision sensor 233. The 3D vision sensor 233 is detachably installed on the L-shaped plate 232. The position of the detection component 23 is adjusted by changing the position of the station part 22, so that the 3D vision sensor 233 continuously detects the products of the station part 22.

[0046] Among them, it should be noted that the 3D vision sensor 233 is a relatively mature existing technology, and this application will not elaborate further.

[0047] For reference Figure 3, the waste collection assembly 24 includes a waste pipe 241 and a waste bin 242. The waste pipe 241 is communicatively provided at the bottom of the square frame 211, and the waste bin 242 is provided on the support plate 213 to receive waste at the bottom of the waste pipe 241. When the detection device 2 detects a problem with the product, the clamp at the front end of the material taking robot 1 is displaced at the connection between the waste pipe 241 and the square frame 211, and the clamp is opened to cause the problematic product to fall into the waste pipe 241 and then into the waste bin 242, and then it is uniformly processed manually later. For the products that pass the inspection, they are transported by the material taking robot 1 and sent to the discharge conveyor line 3 for the next process.

[0048] In the present utility model, the working steps of the device are as follows:

[0049] 1. First, place the product on the detection station (i.e., the station shaft 224) through the material taking robot 1;

[0050] 2. Second, the material taking robot 1 sends a signal to the 3D vision sensor 233 through the PLC system, and the 3D vision sensor 233 starts visual inspection;

[0051] 3. Then, drive the station shaft 224 to rotate by driving the cylinder 222. During the rotation, the 3D vision sensor 233 performs visual processing and inspection of the images of the anti-rotation teeth for defects, the shape of the acid-proof ring for burrs, material shortage, and the grooves for burrs, etc. on the product on the station shaft 224, and gives the results;

[0052] 4. Finally, for the visual inspection results, the PLC system sends a signal to the material taking robot 1. The qualified products are grabbed by the material taking robot 1 and enter the next working process, and the unqualified products are grabbed by the material taking robot 1 and put into the waste pipe 241 and then into the waste bin 242 for manual processing.

[0053] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present utility model. The scope of protection required by the present utility model is defined by the appended claims and their equivalents.
