[0034] As shown in the figure, an appearance detection unit of a circuit breaker production line includes a frame 1 and a conveyor belt 2 installed on the frame 1, and further includes:

[0035] A photographing platform 3, which is arranged on one side of the conveyor belt 2;

[0036] A photographing mechanism 4, which is installed on the frame 1 and is directly above the photographing platform 3;

[0037] A first pushing mechanism 5, which is arranged on the other side of the conveyor belt 2 and pushes the material to the photographing platform 3;

[0038] A second pushing mechanism 6, which is arranged on one side of the photographing platform 3 and pushes the material to the conveyor belt 2;

[0039] A third pushing mechanism 7, which is arranged on one side of the conveyor belt 2 and pushes the material to the front of the second pushing mechanism 6;

[0040] A waste channel 8, which is installed on the frame 1 and is located on one side of the conveyor belt 2;

[0041] A pushing mechanism 9, which is located on the other side of the conveyor belt 2 and corresponds to the waste channel 8; In this technical solution, the circuit breakers are conveyed by the conveyor belt. Each group of circuit breakers is pushed to the photographing platform by the first pushing mechanism, and then the photographing mechanism takes pictures and identifies the outer surface of the circuit breaker. After the photographing is completed, it is pushed to the front of the second pushing mechanism by the third pushing mechanism, and then pushed back to the conveyor belt by the second pushing mechanism. After that, the pushing mechanism pushes the unqualified products on the conveyor belt into the waste channel, and the qualified products remain on the conveyor belt and flow to the next process, which has the advantages of high working efficiency and high detection accuracy.

[0042] In addition, the first pushing mechanism, the second pushing mechanism and the third pushing mechanism in this embodiment all adopt the structure of a push plate and a cylinder for driving the push plate; an oil cylinder or a linear motor can also be used.

[0043] The photographing mechanism 4 includes:

[0044] A first bracket 41 and a second bracket 42, which are respectively installed on the frame 1;

[0045] A light source 43, which is installed on the first bracket 41 and is directly above the photographing platform 3;

[0046] A first camera 44, which is installed on the first bracket 41 and corresponds to the center position of the light source 43;

[0047] A second camera 45, which is obliquely installed on the second bracket 42 and faces the photographing platform 3. The first camera is aligned to photograph and detect the upper surface of the circuit breaker, and the second camera is aligned to photograph and detect the side surface of the circuit breaker. The light source provides auxiliary illumination.

[0048] A first guardrail mechanism 21 is provided at a position on one side of the conveyor belt 2 corresponding to the first pusher mechanism 5, and a first stop mechanism 22 is provided at a position on the other side of the conveyor belt 2 corresponding to the first pusher mechanism 5. The first guardrail mechanism 21 includes first guard plates 211 located on both sides of the conveyor belt 2 and first supports 212 for installing the first guard plates 211. When the circuit breaker is fed, the first guard plates of the first guardrail mechanism provide a guiding function for the circuit breakers on the conveyor belt, so that each group of circuit breakers can be kept flush. The first stop mechanism can make each group of circuit breakers stop at a position corresponding to the first pusher mechanism, facilitating being pushed into the photographing platform by the first pusher mechanism.

[0049] A first blocking assembly 23 is provided at the end of the first guardrail mechanism 21. The first blocking assembly 23 includes a first block 231 and a first driving member 232 for driving the first block to move horizontally. In this embodiment, the number of circuit breakers in each group is 4. The first block is driven by the first driving member to move horizontally. When the first block extends out, it can block the circuit breaker, separating two groups of circuit breakers, so as to ensure that each action of the first pusher mechanism will only push one group of circuit breakers into the photographing platform. The first driving member adopts a cylinder, an oil cylinder or a linear motor.

[0050] The first stop mechanism 22 includes a first stop block 221 arranged directly above the conveyor belt 2 and a first mounting seat 222 installed on the frame 1 and connected to the first stop block. In this embodiment, the first stop block is hingedly installed on the first mounting seat and can be adjusted to a horizontal state for blocking materials, and when no material blocking is required, it is adjusted to a vertical state to allow the circuit breaker to pass through.

[0051] A limit stop bar 31 is provided on the side of the photographing platform 3 away from the conveyor belt 2, and a second stop mechanism 24 is provided at one end of the photographing platform 3 away from the third pusher mechanism 7. The first pusher mechanism pushes the circuit breaker onto the photographing platform until it is blocked by the limit stop bar, and the second stop mechanism blocks the circuit breaker pushed from the third pusher mechanism.

[0052] The second material blocking mechanism 24 includes a second material blocking block 241 and a second driving member 242 for driving the second material blocking block 241 to move horizontally. The second material blocking block can be driven by the second driving member to adjust its position, so that the circuit breaker blocked by the second material blocking block can be just in front of the second material pushing mechanism. The second driving member adopts a cylinder, an oil cylinder or a linear motor.

[0053] On both sides of the position of the conveyor belt 2 between the photographing platform 3 and the waste channel 8, there are second guardrail mechanisms 25. The second guardrail mechanisms 25 include second guard plates 251 located on both sides of the conveyor belt 2 and second supports 252 for installing the second guard plates 251; the second guard plates of the second guardrail mechanisms provide a guiding function for the circuit breakers on the conveyor belt, so that each group of circuit breakers can be kept flush.

[0054] The pushing mechanism 9 includes a second mounting seat 91 installed on the frame 1, a third driving member 92 installed on the second mounting seat, and a push plate 93 connected to the output end of the third driving member. When the circuit breaker detected as a defective product passes through the pushing mechanism, the push plate is driven by the third driving member to push the defective product into the waste channel, while the qualified products are sent to the next process by the conveyor belt.

[0055] On one side of the pushing mechanism 9, there is a second blocking assembly 10. The second blocking assembly includes a second blocking block 101 and a fourth driving member 102 for driving the second blocking block to move horizontally. The second blocking block in the second blocking assembly is driven by the fourth driving member to extend out to intercept the defective product, and then the pushing mechanism performs the pushing action.

[0056] Both the third driving member and the fourth driving member adopt a cylinder, an oil cylinder or a linear motor.
