[0042] It is worth mentioning that the collecting mechanism 7 includes a supporting frame 71, a defective product platform 72, a third lifting cylinder 73, a bracket 74, a pushing cylinder 75, and a defective product frame 76. The supporting frame 71 is connected and fixed to the conveyor belt 2.

When the piston rod of the third lifting cylinder 73 is retracted, the stopper 78 is retracted to allow the miniature circuit breaker to continue to move forward.

[0044] It is worth mentioning that the bracket 74 is installed and fixed on the support frame 71 and is located on the other side of the conveyor belt 2.

[0045] It is worth mentioning that a second telescopic cylinder 21 is provided at the front end of the conveyor belt 2, the conveyor belt 2 is provided with a pressure block 22, a second sensor 23 is provided at the top of the telescopic cylinder, and the second telescopic cylinder 21 is provided with a push rod 24 for extending and abutting the miniature circuit breaker so that the miniature circuit breaker is close to the pressure block 22. The second telescopic cylinder 21 is linked with the second sensor 23. When the second sensor 23 detects that a miniature circuit breaker passes by, the second telescopic cylinder 21 extends the piston rod, so that the push rod 24 presses the miniature circuit breaker against the pressure block 22, so as to prevent the miniature circuit breaker that continues to move from squeezing the miniature circuit breaker in front and causing the miniature circuit breaker in front to fall over.

[0046] The use principle of the utility model is now described as follows:

[0047] The conveyor belt 2 continuously conveys the miniature circuit breakers, and the second sensor 23 counts each miniature circuit breaker. When the number of miniature circuit breakers meets the number of miniature circuit breakers required to be carried by the support frame 33, the piston rod of the second telescopic cylinder 21 extends, and the push rod 24 pushes the miniature circuit breaker to be pressed against the pressure block 22, so that the fixed miniature circuit breaker acts as a barrier to prevent the subsequent miniature circuit breakers from continuing to move forward.

[0048] When the first sensor 32 detects the miniature circuit breaker, it means that the multiple miniature circuit breakers have entered the upper part of the support frame 33, and the piston rod of the second lifting cylinder 34 on the right side of the support frame 33 extends upward, and the blocking plate 35 rises together, and blocks the miniature circuit breaker from continuing to move to the next process;

[0049] When multiple miniature circuit breakers are in place, the piston rod of the second lifting cylinder 34 on the left side of the support frame 33 extends upward, and the blocking plate 35 rises together. At this time, the count is reset, the second telescopic cylinder 21 is reset, and the second sensor 23 counts again, and the number of multiple miniature circuit breakers flows into the space between the second telescopic cylinder 21 and the blocking plate 35 of the second lifting cylinder 34 on the left side of the support frame 33 in advance;

[0050] The piston rod of the first lifting cylinder 31 moves upward to raise the height of the multiple miniature circuit breakers. When the height reaches the specified height, the clamping cylinder 4 of the first platform 11 operates to make the clamping plate close to the miniature circuit breakers on the outermost sides, which not only plays a fixing role, but also reduces the distance between the miniature circuit breakers so that they are close to each other.

[0051] The piston rod of the first cylinder 51 extends out, pushing the first movable plate 52 toward the miniature circuit breaker. At the same time, the second cylinder 53 operates, pushing the support plate 55 downward, so that the electrode block 54 and the wiring cavity of the miniature circuit breaker are on the same axis, until the electrode block 54 is inserted and electrically connected to the wiring terminal of the miniature circuit breaker, the first telescopic cylinder 61 operates, pushing the second movable plate 62 to move, and the pushing part 63 pushes the handle of the miniature circuit breaker to move, disconnecting the connection between the moving contact and the static contact inside the miniature circuit breaker, and then the first telescopic cylinder 61 is reset. At the same time, the withstand voltage detector 13 measures the withstand voltage value between the moving contact and the static contact in the miniature circuit breaker through the electrode block 54;

[0052] After the detection is completed, the second cylinder 53, the first cylinder 51, the clamping cylinder 4, and the first telescopic cylinder 61 are reset successively. At this time, the second lifting cylinder 34 on the right side of the support frame 33 is reset, so that the miniature circuit breakers that have completed the withstand voltage test flow to the lifting mechanism 3 under the second platform 12. When the second platform 12 has not completed the detection of the miniature circuit breakers, the miniature circuit breakers that have completed the detection of the first platform 11 can flow in advance between the blocking plate 35 on the right side of the support frame 33 under the first platform 11 and the blocking plate 35 on the left side of the support frame 33 under the second platform 12;

[0053] The piston rod of the first lifting cylinder 31 moves upward to raise the height of the multiple miniature circuit breakers. When the specified height is reached, the clamping cylinder 4 of the second platform 12 operates to make the clamping plate close to the miniature circuit breakers on the outermost sides.

[0054] The piston rod of the first cylinder 51 extends to push the first movable plate 52 toward the miniature circuit breaker. At the same time, the second cylinder 53 operates to push the support plate 55 downward, so that the electrode block 54 and the wiring cavity of the miniature circuit breaker are on the same axis until the electrode block 54 is inserted and electrically connected to the wiring terminal of the miniature circuit breaker.

[0055] The first telescopic cylinder 61 located on both sides of the clamping cylinder 4 operates and switches the miniature circuit breaker back and forth between the opening and closing states within a certain period of time. This operation not only verifies whether the miniature circuit breaker is opened and closed smoothly through the operating handle, but also detects whether the resistance value when closing is within the standard range through the action characteristic detector 14. After the resistance value item is detected, the miniature circuit breaker is in the closed state, and the overload current is transmitted to the miniature circuit breaker through the action characteristic detector 14 to detect whether the miniature circuit breaker can judge and make a tripping and opening action. When the above items are detected, the first lifting cylinder 31 is reset, and the blocking plate 35 located on the right side of the support frame 33 is reset, so that the miniature circuit breaker continues to move forward;

[0056] At the same time, the piston rod of the third lifting cylinder 73 extends to position the stopper 78 on the path of the miniature circuit breaker until the miniature circuit breaker contacts the stopper 78. If one of the withstand voltage value or action characteristic test items of a miniature circuit breaker fails to meet the requirements, the data of the withstand voltage tester 13 and the action characteristic tester 14 are transmitted to the PLC control center in the frame 1. The PLC control center marks the defective products and controls the servo motor 743 to operate so that the moving block 744 moves to the corresponding defective microcircuit breaker. On one side of the type circuit breaker, the piston rod of the push cylinder 75 is extended to push the defective miniature circuit breaker into the defective frame 76. When all the defective miniature circuit breakers in this group are pushed out, the piston rod of the pull rod cylinder 77 is retracted to tilt the defective platform 72. Under the influence of gravity, the defective miniature circuit breaker enters the defective frame 76. At the same time, the third lifting cylinder 73 and the stopper 78 are reset, and the qualified miniature circuit breaker flows to the next process. Then the piston rod of the pull rod cylinder 77 is extended to reset the defective platform 72.

[0057] The above design scheme can enable the product to achieve the advantages of high detection efficiency, improved detection quality and reduced manufacturing costs.

[0058] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
