[0002] The molded case circuit breaker is a protective switch device installed in a power distribution line and capable of automatically cutting off current when the current exceeds the trip setting. The molded case refers to a plastic insulator used as the shell of the switch device. The molded case circuit breaker needs to be detected for performance before leaving the factory. During detection, the molded case circuit breaker needs to be connected to a circuit to simulate its power-on running state. The common molded case circuit breaker detection device in the prior art is usually arranged to detect only a single specification of molded case circuit breaker, which is not adaptable enough. When multiple different specifications of molded case circuit breakers are produced, multiple detection devices need to be prepared for use. Multiple devices occupy a large installation space and require large equipment investment. Therefore, a detection device capable of adapting to multiple specifications of molded case circuit breakers needs to be designed. SUMMARY

In the working process of the automatic detection device in the embodiment, the appropriate blocking and limiting mechanism, lifting mechanism and detection mechanism are controlled to act by a control system (such as a PLC control system) according to the specification of the plastic shell circuit breaker to be detected. In the detection, the plastic shell circuit breaker is placed at the input end of the flow line 2, is conveyed forward by the flow line 2, is lifted upward to the detection mechanism 3 by the lifting mechanism 5 when the plastic shell circuit breaker is blocked and stopped by the corresponding blocking and limiting mechanism, is moved downward to the flow line by the lifting mechanism 5 after the detection is completed, the blocking and limiting mechanism 4 is released from the blocking and limiting of the plastic shell circuit breaker, and the plastic shell circuit breaker is continuously conveyed and output by the flow line 2. The automatic detection device in the embodiment can realize the detection of at least two different specifications of plastic shell circuit breakers on one detection device by arranging at least two detection mechanisms for detecting plastic shell circuit breakers of different specifications and the corresponding blocking and limiting mechanism and lifting mechanism, so that the effect of one device for multiple purposes is achieved, thereby it is not necessary to install multiple detection devices in the workshop to detect plastic shell circuit breakers of different specifications, so that the space required for equipment installation can be saved, the equipment investment is reduced, and good practicability is achieved. In the automatic detection device shown in the drawings, two detection mechanisms are arranged and used for detecting two specifications of plastic shell circuit breakers. In actual operation, the number of the detection mechanisms is not limited to two, and can be three or four.

[0027] As Figures 1 to 2 shown, the flow line 2 comprises two conveying chain plates 21 fixed on the rack 1 and arranged at intervals and in parallel, the plastic shell circuit breaker is placed on the two conveying chain plates 21 at the same time, the two conveying chain plates 21 are synchronously operated to drive the plastic shell circuit breaker to be stably conveyed, and the lifting mechanism and the blocking and limiting mechanism can be installed in the gap between the two conveying chain plates 21.

[0028] The blocking and limiting mechanism 4 is arranged between the two conveying chain plates 21, the blocking and limiting mechanism 4 comprises a blocking piece 41 which can move up and down and a blocking piece driving cylinder 42 fixed on the rack 1 and used for driving the blocking piece 41 to move up and down, the blocking piece 41 can block the plastic shell circuit breaker in the conveying when the blocking piece 41 is raised, the blocking of the plastic shell circuit breaker by the blocking piece 41 is released after the blocking piece 41 is lowered, and the plastic shell circuit breaker can continue to move forward with the flow line 2.

[0029] AsFigure 3 As shown, the lifting mechanism 5 is used to drive the MCC along the up-down direction to move between the flow line 2 and the detection mechanism 3, which includes a lifting plate 51 that can move up and down and a first lifting cylinder 52 that drives the lifting plate 51 to move up and down, the lifting plate 51 is arranged between the two conveying chains 21 and fixed on the rack 1 to drive the MCC to lift, and the MCC is blocked by the blocking limiting mechanism 4 and above the lifting plate, and the first lifting cylinder 52 drives the lifting plate 51 to move upwards to drive the MCC to rise to the detection mechanism 3.

[0030] In a further scheme of the embodiment, as shown, Figures 2 to 3 As shown, the lifting mechanism 5 is arranged with auxiliary clamping mechanisms 53 on both sides, the auxiliary clamping mechanisms 53 include clamping blocks 531 for clamping the MCC, clamping cylinders 533 fixed on mounting seats 532 for driving the clamping blocks 531 to move laterally, and second lifting cylinders 534 fixed on the rack 1 for driving the mounting seats 532 to move up and down; the auxiliary clamping mechanisms 53 are configured to assist in positioning the MCC during up-down lifting movement, specifically, the clamping blocks 531 in the auxiliary clamping mechanisms 53 on both sides clamp the MCC under the driving action of the clamping cylinders 533, and the second lifting cylinders 534 are synchronously extended and retracted while the lifting mechanism 5 drives the MCC to move up and down, so that the MCC is kept stable during up-down lifting movement, and in actual operation, in order to avoid interference with the detection mechanism 3 after the auxiliary clamping mechanisms 53 are lifted, the auxiliary clamping mechanisms 53 can be configured to release the clamping action on the MCC before the MCC reaches the detection mechanism, and the above structure scheme further improves the stability of the MCC during lifting by the lifting mechanism 5.

[0031] As shown, Figures 1 to 2 The flow line 2 is provided with guardrails 6 on both sides, the guardrails 6 are arranged along the flow direction of the flow line 2, and the rack 1 is fixed with adjusting cylinders 7 for adjusting the spacing between the two guardrails 6, and in this scheme, the guardrails 6 on both sides of the flow line 2 can block and limit the MCC from both sides to prevent the MCC from deviating during conveying, and the spacing between the two guardrails 6 is adjusted to accommodate MCCs of different specifications.

[0032] As shown, Figures 3 to 7As shown, the detection mechanism 3 includes a fixed column 31 fixed on the rack 1, a work station plate 32 fixed on the fixed column 31, a tripping drive unit 33 and a closing drive unit 34 mounted on the work station plate 32 for pushing the handle of the MCCB to act, a pressing positioning structure 35 mounted below the work station plate 32 for pressing the MCCB, and an electric contact 36 mounted below the work station plate 32 for lapping with the conductive plate on the MCCB.

In this scheme, the detection mechanism 3 is fixedly installed on the rack 1 by the fixed column 31 and is above the assembly line 2, so as to facilitate the detection of the MCCB. When the MCCB is lifted to the detection mechanism 3, the conductive plate on the MCCB laps with the electric contact 36 to form an electrical connection, and the MCCB is pressed and limited by the pressing positioning structure 35. The handle of the MCCB is pushed by the tripping drive unit 33 and the closing drive unit 34 to perform the tripping and closing actions to adapt to the characteristic test. The tripping drive unit 33 and the closing drive unit 34 each include a pushing block 331 for pushing the handle and a pushing cylinder 332 for driving the pushing block 331 to move, and the pushing cylinder 332 is fixed on the work station plate 32.

When the MCCB is lifted to the detection mechanism 3 by the lifting mechanism, the limiting baffle 37 is resisted on the upper part of the MCCB, thereby playing a role of limiting the downward resistance of the MCCB, and further ensuring the stability of the MCCB at this position, so as to facilitate the detection operation.

[0034] As shown in Figures 1 to 2 The end of the assembly line 2 is also provided with a pushing mechanism 8 for pushing the MCCB out of the assembly line 2.
