Description

Technical Field

[0001] The utility model relates to the technical field of sensor welding, in particular to a fully automatic laser welding device for a temperature sensor of a new energy vehicle. Background Art

[0002] A sensor is a device that can sense and measure changes in physical, chemical, or biological parameters and convert them into readable or processable signals. A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are also used in new energy vehicles to detect the temperature of the engine compartment. During the production of temperature sensors, the sensors need to be sealed using laser welding equipment.

[0003] The existing patent with the authorization announcement number "CN113510426A" discloses a temperature sensor welding device, including a base and a top seat, wherein the base and the top seat are connected by a support member, and further comprising: a fixing mechanism, the fixing mechanism being provided on the base and used to fix the temperature sensor to be processed; a wire binding mechanism, the wire binding mechanism being provided on the top seat and used to fix the lead to be welded; and a welding mechanism. The present invention can drive the fixing mechanism to rotate through a synchronization mechanism, and make the wire binding mechanism rotate synchronously, so that the welding path can rotate in a circular manner, making it more convenient for the welding mechanism to perform welding, ensuring the flatness of the welding line, and improving the welding effect.

[0004] However, there are the following deficiencies in this device:

[0005] 1. When the sensor is welding, some harmful smoke will be generated, so it is necessary to exhaust the smoke through a smoke exhaust fan. However, when the above device is in use, the opening and closing of the smoke exhaust fan must be controlled separately, which reduces the intelligence of the welding equipment;

[0006] 2. When welding the sensor, dust adhering to the welding position will affect the welding quality of the sensor and reduce the sealing effect. However, when the above device is used, it fails to automatically clean the dust at the welding position before welding, which reduces the welding quality of the device. Utility Model Content
