Description

Technical Field

[0001] This utility model relates to the field of vacuum circuit breaker testing technology, specifically to an automatic appearance inspection device with automatic rejection function. Background Technology

[0002] Vacuum circuit breakers are named for their high-vacuum arc-extinguishing medium and the high-vacuum insulation medium in the contact gap after arc extinguishing. They are characterized by their small size, light weight, suitability for frequent operation, and maintenance-free arc extinguishing, making them widely used in power distribution networks. Vacuum circuit breakers are indoor power distribution devices in 3-10kV, 50Hz three-phase AC systems, used in industrial and mining enterprises, power plants, and substations for the protection and control of electrical equipment. They are particularly suitable for applications requiring oil-free operation, minimal maintenance, and frequent operation. Circuit breakers can be installed in medium-voltage switchgear, double-layer switchgear, and fixed switchgear for the control and protection of high-voltage electrical equipment.

[0003] Vacuum circuit breakers typically have nameplates for opening and closing handles, energy storage indicators, connection plates, pole markings, aviation plug caps, and electronic tags. Before leaving the factory, various indicator plates on the appearance of vacuum circuit breakers need to be inspected to check whether they are installed and in the correct position. Existing vacuum circuit breaker appearance inspection devices will issue an alarm when they detect unqualified products, requiring staff to pick out the unqualified vacuum circuit breakers, which greatly reduces the inspection efficiency of vacuum circuit breakers.

[0024] Example 1:

[0025] Please see Figures 1-3 This utility model provides an automatic appearance inspection device with an automatic rejection function, the technical solution of which is as follows:

[0026] An automatic appearance inspection device with automatic rejection function includes a conveyor frame 1, a conveyor belt 2 inside the conveyor frame 1, a support frame 3 fixedly installed at the upper end of the conveyor frame 1, a first industrial camera 4 fixedly installed at the top of the support frame 3, a second industrial camera 5 fixedly installed on the inner side walls at both the front and rear ends of the support frame 3, a control panel 6 fixedly installed on the outer side wall of the support frame 3, a first unloading plate 7 installed at one end of the conveyor frame 1, a second unloading plate 8 installed on one side of the conveyor frame 1, and a pusher plate 9 installed at one end of the second unloading plate 8.

[0027] In a preferred embodiment, a drive motor 10 is fixedly installed on one side of the conveyor frame 1. The output shaft of the drive motor 10 is fixedly connected to the transmission roller of the conveyor belt 2. The drive motor 10 facilitates the conveying control of the conveyor belt 2, and the use of a servo motor in the drive motor 10 facilitates the adjustment of the conveying speed of the conveyor belt 2.

[0028] In a preferred embodiment, one end of the pusher plate 9 is fixedly connected to the telescopic end of the hydraulic telescopic cylinder 11, which is fixedly mounted on the conveyor frame 1. When the telescopic end of the hydraulic telescopic cylinder 11 extends, it can push the pusher plate 9 to move, thereby pushing the vacuum circuit breaker to move towards the second unloading plate 8.

[0029] In a preferred embodiment, the control panel 6 is electrically connected to the first industrial camera 4, the second industrial camera 5, the drive motor 10, and the hydraulic telescopic cylinder 11. The control panel 6 controls the operation of the drive motor 10 and the hydraulic telescopic cylinder 11, thereby achieving a high degree of automation of the equipment.

[0030] In a preferred embodiment, the ends of the first unloading plate 7 and the second unloading plate 8 away from the conveyor frame 1 are both hinged with overlapping plates 12. Limit bars 13 are fixedly provided on both sides of the upper end of the first unloading plate 7 and the second unloading plate 8. Ball bearings 14 are embedded in the upper surface of the first unloading plate 7 and the second unloading plate 8. The overlapping plate 12 at the lower end of the first unloading plate 7 overlaps on the qualified product conveyor belt 15, and the overlapping plate 12 at the lower end of the second unloading plate 8 overlaps on the unqualified product conveyor belt 16. The overlapping plates 12 on the conveyor belts can transport the tested vacuum circuit breakers to the corresponding processes. For example, qualified products are transported to the packaging area via the qualified product conveyor belt 15, while unqualified products are transported to the rework area via the unqualified product conveyor belt 16.

[0031] The working principle of this utility model is as follows:

[0032] In operation, the vacuum circuit breaker to be tested is placed on conveyor belt 2. Drive motor 10 drives conveyor belt 2 to transport the vacuum circuit breaker. Under the action of conveyor belt 2, the vacuum circuit breaker passes through support frame 3, and then passes the first industrial camera 4 and the second industrial camera 5 inside support frame 3. The first and second industrial cameras 4 and 5 capture images of the vacuum circuit breaker's appearance and send them to control panel 6. The analysis and processing module inside control panel 6 analyzes and processes the images captured by the first and second industrial cameras 4 and 5, checking whether the various indicator signs on the outer surface of the vacuum circuit breaker are complete and correctly positioned. If the appearance of the vacuum circuit breaker is found to be qualified, the drive... Motor 10 continues to drive conveyor belt 2 to transport the vacuum circuit breaker to the first unloading plate 7, causing the vacuum circuit breaker to slide down along the first unloading plate 7 onto the qualified product conveyor belt 15, and the qualified vacuum circuit breaker is transported to the packaging area for packaging; if the vacuum circuit breaker is detected to be unqualified, when the vacuum circuit breaker is transported to the pusher plate 9, the drive motor 10 is turned off, and then the hydraulic telescopic cylinder 11 is opened. The hydraulic telescopic cylinder 11 pushes the pusher plate 9 to move, and the pusher plate 9 pushes the unqualified vacuum circuit breaker to the second unloading plate 8, causing the unqualified vacuum circuit breaker to slide along the second unloading plate 8 onto the unqualified product conveyor belt 16, and the unqualified product conveyor belt 16 is used to transport the product to the rework area for relabeling and other operations.

[0033] Example 2:

[0034] Please see Figure 1 and Figure 4 Two guide plates 17 are hinged to the inner side wall of the support frame 3. A spring 18 is provided at the outer end of the guide plate 17. One end of the spring 18 is fixed to the inner side wall of the support frame 3. An infrared sensor 19 is embedded in the inner side wall of one of the guide plates 17. A support plate 20 is hinged to the lower end of the support frame 3. Several limiting grooves 21 are evenly spaced at the bottom ends of the first unloading plate 7 and the second unloading plate 8.

[0035] When the unloading plate overlaps with the conveyor belt, the overlapping plate 12 overlaps the qualified product conveyor belt 15 and the unqualified product conveyor belt 16. After the overlap is completed, the support plate 20 is inserted into the corresponding limiting groove 21 to support the unloading plate. When the vacuum circuit breaker passes the support frame 3, the two guide plates 17 can align the vacuum circuit breaker to the middle. If the vacuum circuit breaker is detected to be unqualified, as the vacuum circuit breaker is conveyed, when the vacuum circuit breaker separates from the guide plate 17, the control panel 6 starts timing. The time for the vacuum circuit breaker to reach the push plate 9 is determined according to the transmission speed of the conveyor belt 2. Then the drive motor 10 is turned off, and the push plate 9 is used to push the vacuum circuit breaker into the second unloading plate 8.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
