Description

Technical Field

[0001] The present application relates to the technical field of online detection of circuit breaker production and manufacturing, and specifically to a circuit breaker four-test integrated detection platform. Background Art

[0002] For circuit breakers or other similar products, most of the loop resistance and withstand voltage tests of new products are done manually. The tester uses a loop resistance meter to manually test the loop resistance, and a withstand voltage meter to manually test the withstand voltage. When manually testing the loop resistance, any pressure on the hand will affect the test results; manually testing the withstand voltage is time-consuming and has safety hazards; and the operating force and mechanical running-in, including the opening force, closing force, and tripping force, are tested on different devices separately, which increases the workload of employees. The equipment is also relatively simple. Since the testing equipment is a random inspection equipment, it cannot meet the needs of large-scale testing. There are also some equipment in the industry for loop resistance, withstand voltage, operating force, and mechanical running-in testing, but either the degree of automation is not high, or the four tests cannot be combined on one device. For example, the patent document with application publication number CN110082351A discloses a circuit breaker detection production line, including: an electrical performance detection unit, which is used to detect the electrical performance of the circuit breaker. The electrical performance only includes electrical performance such as dielectric properties, insulation resistance and impulse withstand voltage, and cannot be installed in the same workstation for mechanical running-in and operating force testing; the patent document with application publication number CN116443557A discloses a vacuum circuit breaker assembly and detection production line including a withstand voltage test component and a running-in chamber, but the running-in chamber and the withstand voltage test component are not in the same workstation, and there is no way to perform operating force testing; the patent document with authorization announcement number CN106252165B discloses an automatic circuit breaker production line including a running-in mechanism and a comprehensive test bench. The running-in mechanism performs a running-in test on the circuit breaker. The comprehensive test bench includes a large current test component, a performance test component and a withstand voltage test component. The running-in mechanism and the comprehensive test bench are also far apart and cannot be completed in one workstation. Therefore, most of the solutions in the prior art are single-function machines or integrate a few detection functions, and it takes two workstations to achieve the integration of several functions, resulting in low detection efficiency.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

The barcode cylinder 53 is installed on the outer wall of the detection room 2 along the Z-axis direction through the barcode cylinder fixing plate 54 in the XZ plane. In the embodiment, the barcode cylinder fixing plate 54 is an aluminum plate, which can be installed with barcode cylinders 53 of various strokes. The barcode gun fixing plate 52 is made of sheet metal and is horizontally fixed on the moving part at the bottom of the barcode cylinder 53. The front end is bent downward to an angle of 30° suitable for scanning codes. The barcode gun 51 is installed on the bend of the barcode gun fixing plate 52.

The contact groove side of the clamping block 311 is The surface is also provided with an insulating rod hole 3111 penetrating the entire clamping block 311 along the Y-axis direction. In this embodiment, the eight contacts 313, which are the same number as the single-side connecting plate of the circuit breaker 11, are fixed to the bottom of the clamping block 311 by insulating rods 314 passing through the insulating rod holes 3111 so that the front is connected to the connecting plate when the clamping block 311 is clamped. The top of the contact 313 is also provided with vertical springs 315 on both sides of the insulating rod 314, which are connected to the contact grooves of the clamping block 311. The cross section of the clamping block 311 along the direction of the clamping surface is an inverted L-shaped, and the circuit breaker 11 can be well fixed from the top when clamped, and at the same time, the withstand voltage contact 313 contacts the side connection plate of the circuit breaker 11, and the connection plate is stably connected under the action of the spring 315. In this scheme, the contact 313 can not only be used as a conductor for testing withstand voltage, but also as a conductor for measuring the internal resistance of the circuit and for conducting judgment during mechanical running-in, achieving a multi-purpose effect. The implementation method of the drawer assembly 31 is not limited to the method described in this embodiment, and can be adaptively changed according to the direction in which the circuit breaker 11 is placed on the support plate 1a.

The switch-on / off module mounting plate 327 is horizontally mounted on the table through columns at four corners. The switch-on / off linear module 323 is invertedly mounted below the switch-on / off module mounting plate 327 along the switch-on / off direction of the circuit breaker 11 handle. The switch-on / off cylinder 325 is mounted at one end of the switch-on / off linear module 323. The switch-on / off linear module 323 can drive the lower mechanism to the left under the drive of the switch-on / off cylinder 325. Right movement, the splitting and closing slider plate 326 is installed and fixed on the bottom of the slider of the splitting and closing linear module 323 along the installation direction of the splitting and closing linear module 323, and the two ends of the splitting and closing slider plate 326 extend downward to respectively install splitting and closing card grab plates 321, and the inner sides of the bottoms of the splitting and closing card grab plates 321 are respectively installed with horizontal rubber-coated wheels 324 perpendicular to the splitting and closing direction of the circuit breaker 11 handle through bayonet-shaped rubber-coated wheel fixing blocks 329, the vertical position of the rubber-coated wheels 324 is adapted to the circuit breaker 11 handle and the spacing between the rubber-coated wheels 324 is greater than the stroke of the circuit breaker 11 handle, and the rubber-coated wheels 324 are pushed from the forward and reverse directions of the circuit breaker 11 handle to play the role of splitting and closing. A tripping cylinder 3281 is also installed on the opening and closing module mounting plate 327. The tripping rod 328 is vertically installed below the opening and closing module mounting plate 327 at the bottom of the tripping cylinder and its horizontal position is the same as the horizontal position of the tripping button of the circuit breaker 11. For example, the circuit breaker 11 products of this embodiment are also divided into two different specifications of products, three-pole and four-pole. The three-pole product has a 3P tripping button 111, and the four-pole product has a 4P tripping button 112. Their tripping button positions are 70MM apart, so when testing the tripping force, the entire drawer assembly 31 has to move another 70MM so that the position of the tripping cylinder 3281 can be aligned with the tripping button. A force sensor 322 in the same direction as the opening and closing direction of the circuit breaker 11 handle is installed between each of the rubber-coated wheel fixing blocks 329 and the opening and closing card grab plate 321. The two force sensors 322 can measure the opening force and the closing force respectively. A vertical force sensor 322 is installed on the trip rod 328. In this embodiment, the force sensor 322 is set in the middle of the trip rod 328 to measure the trip force. The handle of the circuit breaker 11 product can be effectively protected by the setting of the rubber-coated wheel 324. The opening and closing assembly 32 can also have other structural forms, such as a structure that can grab the handle from the top and set a force sensor 322 on the side.

[0041] The handle pressure-resistant assembly 33 includes a probe 331, a probe 332, a top bracket 333 and a probe cylinder 334. The top bracket 333 is vertically installed below the opening and closing module mounting plate 327 along the opening and closing direction of the circuit breaker 11 handle. The probe 332 is installed at the bottom of the top bracket 333 through a probe cylinder 334 horizontally installed at the tail perpendicular to the opening and closing direction of the circuit breaker 11 handle. The probe 331 is horizontally installed at the head of the probe 332 perpendicular to the opening and closing direction of the circuit breaker 11 handle. When the probe 331 is extended under the action of the probe cylinder 334, it touches the circuit breaker 11 handle to detect the pressure resistance.
