Description

Technical Field

[0001] The present invention relates to the field of temperature sensor welding, and particularly to a welding device for temperature sensor production. Background Art

[0002] A temperature sensor refers to a sensor that can sense temperature and convert it into an available output signal. The temperature sensor is the core part of a temperature measuring instrument, with a wide variety of types. It can be divided into two major categories: contact type and non-contact type according to the measurement method, and into two categories: thermal resistance and thermocouple according to the sensor material and electronic component characteristics. The temperature sensor mainly consists of components and a housing. The housing prevents physical damage, dust, moisture, and other pollutants from entering, ensuring the normal operation of the internal circuit of the sensor. The housing can shield electromagnetic interference, reduce the interference of external electromagnetic fields on the sensor signal, and improve the measurement accuracy. Therefore, the housing of the temperature sensor plays an important role in protecting internal components, ensuring measurement accuracy and stability, etc. The cylindrical housing is one of the most common shapes. This shape of the housing has good symmetry and stability, is convenient for installation and fixation, and is suitable for most occasions.

[0003] During the production process of the temperature sensor, the housing of the temperature sensor is usually connected by welding. Because the housing of the temperature sensor connected by welding has better sealing performance, it can effectively prevent dust and moisture from entering its interior and damaging the internal components. Moreover, the welded housing of the temperature sensor enhances the structural strength, making it more capable of withstanding mechanical stresses such as vibration and impact. In addition, welding reduces seams and gaps, and can be applied to different usage environments. Welding the temperature sensor requires the use of a welding device.

[0004] The welding device for the temperature sensor housing usually consists of a fixture, a driving mechanism, and a welding mechanism. The fixture is used to fix the housing of the temperature sensor, the welding mechanism is used to weld the housing of the temperature sensor, and the driving mechanism drives the fixture to rotate, so that the welding torch can weld different positions of the temperature sensor housing.

[0005] However, during use, according to the usage requirements of the temperature sensor, the radii of the temperature sensors are different. Therefore, when welding the housings of temperature sensors with different radii, it is necessary to adjust the distance between the welding torch and the housing to keep the best welding distance between the welding torch and the housing. Especially when the housing specifications need to be frequently changed on the production line, the above method takes a lot of time. Secondly, the housing may be contaminated with dust during processing, transportation, or storage, and at the same time, the dust present in the welding environment may fall on the surface of the workpiece. The dust and impurities will scatter and absorb the laser energy, resulting in insufficient laser energy in the welding area and unable to fully melt the material, leading to problems such as insecure welding and false soldering. Based on the above problems, this application proposes a welding device for temperature sensor production. Summary of the Invention

[0021] Compared with the prior art, the present invention provides a welding device for producing temperature sensors, which has the following beneficial effects:

[0022] 1. A welding device for producing temperature sensors can adjust the position of a laser welding gun through an adaptive welding component, wherein the adaptive welding component is adaptively adjusted according to the radius of the temperature sensor housing, thereby avoiding the need to adjust the distance between the laser welding gun and the temperature sensor housing when welding different temperature sensor housings, so that the laser welding gun and the temperature sensor housing maintain an optimal welding distance, avoiding the reduction in welding quality of the temperature sensor housing due to too close or too far distance, and avoiding the need to spend a lot of time adjusting the laser welding gun when the housing specifications need to be frequently changed on the production line.

However, the servo motor cannot drive the rotating cylinder and the connecting cylinder to rotate through the transmission component. When the servo motor rotates in reverse, the transmission component drives the rotating cylinder and the connecting cylinder to rotate, while the servo motor cannot drive the rotating shaft to rotate through the connecting component. Thus, by using a single servo motor, the outer shell of the temperature sensor can be driven to move to the dust removal and welding positions, and the outer shell of the temperature sensor can be made to rotate.

Then drive the rotation of the rotating round shaft 131 by the output end of the servo motor 3, so that the rotating round shaft 131 drives the rotating disk 132 to rotate. The rotating disk 132 drives the one-way pushing block 133 to move, so that the vertical surface of the one-way pushing block 133 pushes the vertical surface of the connecting block 138, and the one-way pushing block 133 drives the moving disk 137 to rotate through the connecting block 138. The connecting block 138 drives the connecting shell 134 to rotate through the rectangular groove and the rectangular column, and drives the rotating shaft 4 to rotate through the connecting shell 134, so that the rotating shaft 4 drives the fixed frame 6 to rotate. The fixed frame 6 drives the rotating shaft 71 and the electric push rod 72 to move. The rotating shaft 71 drives the installation shell 76 to move, so that the installation shell 76 drives the clamping block 710 to move through the connecting column 79. At the same time, the electric push rod 72 drives the fixed seat 711 to move through the bearing, so that the fixed seat 711 drives the top block 712 to move, and the top block 712 and the clamping block 710 drive the temperature sensor shell to move. During this process, the pushing sleeve 107 is separated from the pushing column 106, so the driven transmission wheel 103 cannot drive the pushing sleeve 107 to rotate through the installation sleeve 104 and the pushing column 106, and the pushing sleeve 107 cannot drive the circular column 1012 to rotate through the moving sleeve 108 and the limiting convex strip 109, so that the rotating cylinder 8 and the connecting cylinder 9 do not rotate. When the temperature sensor shell contacts the adjusting ball 116, the temperature sensor shell pushes the arc plate 115 to move to the left through the adjusting ball 116, so that the arc plate 115 drives the connecting circular plate 113 to stretch the spring 114 through the adjusting rod 112. The adjusting rod 112 drives the dust suction pipe 119 to slide inside the installation vertical plate 111 through the installation plate 118, and drives the dust suction cover 1110 to move to the left through the dust suction pipe 119, so that the dust suction cover 1110 drives the cleaning brush 1111 to move to the left, and the dust suction cover 1110 and the cleaning brush 1111 are adjusted according to the radius of the temperature sensor shell. When the shell for cleaning dust moves to the rear side, it will push the arc plate 125 to move to the rear side through the adjusting ball 126, so that the arc plate 125 drives the moving circular plate 123 to stretch the spring 124 through the moving rod 122. The moving rod 122 drives the smoking pipe 129 and the laser welding gun 1210 to move to the rear side through the connecting plate 128, so that the positions of the smoking pipe 129 and the laser welding gun 1210 are adjusted according to the radius of the temperature sensor shell. When the temperature sensor shell contacts the middle adjusting ball 116 and the adjusting ball 126, the servo motor 3 stops running.At this time, the hydraulic push rod 1011 drives the output end to drive the moving plate 1010 to move downward, so that the moving plate 1010 drives the moving sleeve 108 to move downward, and the moving sleeve 108 pushes the pushing sleeve 107 to move downward, so that the pushing column 106 is inserted into the inside of the pushing sleeve 107. At this time, the output end of the servo motor 3 reverses, so that the driving transmission wheel 101 drives the driven transmission wheel 103 to rotate through the transmission belt 102, and drives the mounting sleeve 104 to rotate through the driven transmission wheel 103. The mounting sleeve 104 drives the pushing sleeve 107 to rotate inside the moving plate 1010 through the pushing column 106. The pushing sleeve 107 drives the circular column 1012 to rotate through the limiting convex strip 109, so that the circular column 1012 drives the rotating cylinder 8 and the connecting cylinder 9 to rotate, so that the rotating cylinder 8 and the connecting cylinder 9 drive the driving gear 5 to rotate at the same time, and drive the connecting gear 73 to rotate through the driving gear 5, so that the connecting gear 73 drives the rotating shaft 71 to rotate. The rotating shaft 71 drives the mounting housing 76 to rotate. The mounting housing 76 drives the clamping block 710 to rotate through the connecting column 79, so that the clamping block 710 drives the temperature sensor housing to rotate. The temperature sensor housing drives the fixed seat 711 to rotate through the bearing through the top block 712. When the temperature sensor housing rotates, the dust on the temperature sensor housing is swept off by the cleaning brush 1111, and the swept dust is sucked away through the dust suction pipe 119 and the dust suction hood 1110. And the temperature sensor housing is welded by the laser welding gun 1210, and the welding fume generated by welding is sucked away through the fume suction pipe 129. During this process, the rotating circular shaft 131 drives the one-way pushing block 133 to move reversely through the rotating disk 132, so that the inclined surface of the one-way pushing block 133 contacts the arc surface of the connecting block 138, so that the one-way pushing block 133 pushes the connecting block 138 to move upward, so that the connecting block 138 pushes the moving disk 137 to compress the vertical spring 136, then the connecting housing 134 will not drive the rotating shaft 4 to rotate.,
