Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, specifically to an automatic adhesive coating equipment for the moving contacts of a molded case circuit breaker. Background Technology

[0002] A molded case circuit breaker (MCCB) is a switching device that automatically disconnects a circuit when it experiences overload, short circuit, or undervoltage faults, and is widely used in low-voltage power distribution systems. Its moving contact, as the core moving component of the contact system, contacts the stationary contact to conduct the circuit when the circuit breaker is closed, and separates from the stationary contact to disconnect the circuit when it is open. During long-term use, the moving contact needs to withstand the combined effects of mechanical shock, arc erosion, and environmental corrosion. To reduce the contact resistance on the contact surface and prevent oxidation, current technology typically coats the surface of the moving contact with conductive paste or contact grease. This coating effectively reduces the contact resistance and temperature rise at the conductor contact point, improves conductivity, and provides corrosion protection.

[0003] However, the existing adhesive coating process for moving contact assemblies has the following shortcomings: the coating method is relatively outdated, and most existing technologies rely on manual application or simple spraying tools, resulting in low operating efficiency and difficulty in accurately controlling the coating thickness. This can easily lead to uneven coating, local accumulation, or missed coating, which directly affects the conductivity stability and service life of the contacts. Moving contact assemblies usually contain multiple contacts, and traditional adhesive coating equipment often uses a single nozzle to spray one by one. This not only takes a long time, but also makes it difficult to ensure the consistency of adhesive coating between contacts, which can easily lead to differences in contact resistance between different contacts and affect the overall performance consistency of the circuit breaker.

[0004] In view of this, there is an urgent need to design an automatic glue-applying device for the moving contacts of molded case circuit breakers in order to solve the technical defects in the existing glue-applying process for the moving contacts of molded case circuit breakers.

[0008] The present invention is further configured such that a first glue application detection probe is connected to the outside of the glue application gun, and a second glue application detection probe is connected to the contact glue application bracket. The first glue application detection probe is used to detect the distance between the glue outlet of the glue application gun and the contact of the contact assembly, and the second glue application detection probe is used to detect the distance between the contact glue application mechanism and the positioning fixture.

[0011] The present invention is further configured such that the component pressing mechanism includes a component pressing bracket, a component pressing power source connected to the component pressing bracket, and a component pressing member driven by the component pressing power source. The component pressing member has a pressing end on the side near the positioning fixture. The pressing end is used to press the contact component on the positioning fixture. The component pressing bracket is located next to the contact adhesive bracket.

[0012] The present invention is further configured such that the component flipping mechanism includes a component flipping base plate, a flipping lateral movement force source connected to the component flipping base plate, a flipping lateral movement support plate driven by the flipping lateral movement force source, a first flipping vertical movement force source connected to the flipping lateral movement support plate, a first flipping vertical movement plate driven by the first flipping vertical movement force source, a flipping module connected to the first flipping vertical movement plate, a flipping clamping power source connected to the flipping module, and a flipping clamping claw driven by the flipping clamping power source. The flipping clamping claw is used to clamp the contact component on the positioning fixture and flip it.

The positioning tool rotates to the position of the component flipping mechanism, which flips the contact assembly on the positioning tool by 180°. The positioning tool rotates again to the position of the contact gluing mechanism to apply glue to the back side of the first contact of the contact assembly. After applying glue to both sides of the first contact of the contact assembly, the positioning tool... The assembly rotates again to the module loading mechanism station, where it rotates the contact assembly on the positioning fixture 180°. The positioning fixture then rotates to the contact gluing mechanism station, where the module pressing mechanism presses the contact assembly onto the positioning fixture. The contact gluing mechanism then applies glue to the reverse side of the second contact of the contact assembly. The positioning fixture rotates to the module flipping mechanism station, where it flips the contact assembly on the positioning fixture 180°. The positioning fixture then rotates again to the contact gluing mechanism station, applying glue to the front side of the second contact of the contact assembly.
