Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic switch performance testing, and particularly relates to a performance testing device for an automotive magnetic switch. Background Technique

[0002] The automotive magnetic switch, namely the starter electromagnetic switch, is a key component of the automotive electrical system. Through a precise electromagnetic control mechanism, it ensures that the starter starts the engine timely and correctly. When the start command is issued, the current activates the pull-in coil to generate a magnetic field, pulling the iron core forward. On the one hand, it makes the starter drive gear accurately engage with the engine flywheel ring gear. On the other hand, it connects the main circuit of the starter, driving the motor to rotate and drive the engine to start. Subsequently, the holding coil maintains the engaged state until the engine starts. After that, the circuit is disconnected, and the return spring resets the system, protecting the starter from damage while completing the start task. This process reflects the crucial importance of the magnetic switch as the core switch for controlling the starting sequence and power transmission.

[0003] Testing the automotive magnetic switch is of great importance because it directly relates to whether the vehicle can start normally, affecting driving safety and user experience. Firstly, as a key link in the starting system, the performance of the magnetic switch directly affects the response speed and reliability of the starter. Testing can ensure a rapid and effective starting process, avoiding starting delays or failures caused by switch failures. Secondly, through testing, wear, aging, or damage of the magnetic switch can be detected in a timely manner, such as problems like poor contact and weakened electromagnetic attraction, preventing gear slippage or engine damage during starting and reducing maintenance costs. Moreover, testing helps to evaluate the integrity of the starting circuit, ensuring the safety of the circuit when passing a large current and preventing safety hazards such as short circuits and overheating. Finally, regular testing and maintenance of the magnetic switch can also extend the overall life of the starting system, improve the overall reliability and durability of the vehicle, and ensure that users can start the vehicle smoothly whether in daily travel or in an emergency, enjoying trouble-free driving. Therefore, testing the automotive magnetic switch is not only a routine requirement for vehicle maintenance but also an important measure to ensure driving safety and improve vehicle performance. The problems existing in the above technology are: low testing efficiency and discontinuity of the testing process. These problems seriously affect the productivity and quality control level of the automotive repair and manufacturing industries. Specifically, the low testing efficiency is mainly manifested in the long time required for the device to process a single test sample. Coupled with insufficient automation and relying on manual intervention for multi-step operations, the overall detection process is time-consuming and laborious. This situation is particularly prominent when faced with a large number of magnetic switches to be inspected, increasing the production cycle and repair waiting time, and being unfavorable for quickly responding to market demands and improving customer satisfaction.

[0024] The working principle of the present utility model:

[0025] During use, in the modern automotive manufacturing process, the testing of automotive magnetic switches is an essential link. This link not only concerns the quality of automotive switches but also directly relates to the performance and safety of automobiles. Below, we will elaborate on each step in the testing process of automotive magnetic switches to better understand its operating principle and workflow.

[0026] First, workers need to pour automotive magnetic switches into the storage bin one by one through a special feeding plate. The storage bin serves as the starting point of the entire testing process and plays the role of storing and initially classifying magnetic switches. As the switches are continuously poured in, the quantity in the storage bin gradually increases, providing a sufficient material basis for subsequent testing work. Next, the operator controls the motor through the control box to make the motor start running. The motor is the power source of the entire testing process. It drives the rotation of the support rod through a belt. The surface of the support rod is engaged with a transmission belt. In this way, the motor can drive the rotation of the transmission belt by driving the support rod. The rotation of the transmission belt provides power for the subsequent clamping device. On the surface of the transmission belt, a series of clamping devices are arranged. These clamping devices are connected to an air pump through the control box. When the clamping device runs to the upper end of the storage bin, the control box will issue an instruction to make the air pump start working. The air pump pushes the telescopic rod forward, causing the claw to move along the limiting groove opened on the surface of the fixed block. Since the limiting groove is in the shape of being narrow at the front and wide at the back, the claw will gradually clamp inward during the movement, achieving the clamping of the automotive magnetic switch. After the clamping is completed, the conveyor belt continues to drive the clamping device forward. During the forward movement, the clamping device will carry the automotive magnetic switch to the lower end of the detection device. The detection device is responsible for testing various performances of the automotive magnetic switch, such as magnetic force magnitude, switch response speed, etc. These test data are crucial for evaluating the quality of the switch. When the detection is completed, the conveyor belt continues to drive the clamping device forward. When it runs to the upper end of the discharge bin, the control box issues an instruction again to make the air pump drive the telescopic rod to retract. In this way, the claw will release the automotive magnetic switch, causing it to fall into the discharge bin.
