Description

Technical Field

[0001] The utility model belongs to the technical field of plastic product processing, and particularly relates to an assembly machine for plastic shells of electronic components. Background Art

[0002] As is well known, a circuit breaker is an indispensable and important device in the power system. It is a device that can automatically disconnect the circuit when abnormal conditions occur in the circuit, such as overload or short circuit, so as to protect wires and electrical equipment from damage. The circuit breaker housing is one of the key components of the entire circuit breaker and is usually made of engineering plastics with excellent insulation performance.

[0003] The magnetic conductive block in the circuit breaker is an important component and plays a key role in the working process of the circuit breaker. The magnetic conductive block is usually made of high magnetic permeability materials such as silicon steel or ferrite, which can enhance the magnetic field strength inside the circuit breaker and improve the working efficiency of the electromagnetic coil. The main functions of the magnetic conductive block include guiding and concentrating the magnetic field to make the magnetic field distribution more reasonable; accelerating the contact separation to improve the operating speed of the circuit breaker; improving the arc extinguishing effect by affecting the magnetic field distribution; reducing energy consumption; adjusting the operating characteristics of the circuit breaker; and suppressing electromagnetic interference. Through these effects, the magnetic conductive block optimizes the magnetic field distribution and enhances the magnetic field strength, thereby improving the performance, reliability and working efficiency of the circuit breaker and playing an indispensable and important role in the circuit breaker.

[0004] In the production process of existing plastic housings for circuit breakers, the assembly process of the magnetic conductive buckle mainly relies on manual operation. Workers use hand-held jigs to manually fill the metal magnetic conductive block into the designated position of the circuit breaker housing. This method is simple and direct, does not require complex mechanical equipment, and is suitable for small-scale production or the product prototype production stage. However, with the expansion of production scale and the improvement of quality requirements, this manual assembly method has exposed a series of problems:

[0005] First, since the manual feeding speed cannot meet the high daily production capacity requirements of the product, the existing manual operation method is inefficient and has become a bottleneck process restricting production capacity.

[0006] Second, due to the strict requirements for the placement position of the magnetic conductive block and the narrow space, it is difficult to ensure the accuracy of manual operation, which is prone to operation errors, and the situation of the magnetic conductive block being placed in place often occurs, thus affecting the subsequent processes.

[0007] To sum up, the existing manual assembly method of the magnetic conductive block has many deficiencies and is difficult to meet the production requirements. Therefore, it is very necessary to develop a new type of automatic magnetic conductive block assembly machine, which aims to improve production efficiency, ensure the consistency of product quality, and minimize the influence of human factors.
