Description

Technical Field

[0001] The present application relates to the field of soldering equipment, and in particular to a freely adjustable differential pressure core soldering device. Background Art

[0002] In the field of mechanical manufacturing, especially in the soldering process involving differential pressure cores, accurate control of the position of the differential pressure core is crucial to welding quality and production efficiency. With the development of automation and precision machining technology, differential pressure core soldering technology has gradually transitioned from traditional manual operation to automated production mode, greatly improving production efficiency and product quality, and reducing labor costs. However, in these automated soldering equipment, how to achieve high-precision adjustment of the position of the differential pressure core is still a challenge. To solve this problem, the existing technical means are mainly the following. One is to use a fixed structure to position the differential pressure core, that is, to fix the differential pressure core in a predetermined position using a rigid fixture, and then move the fixture manually or by a mechanical arm to achieve preliminary positioning. Although this method has a simple structure, its accuracy is limited by manual adjustment; the other is to completely rely on the servo motor and the mechanical guide rail system to achieve fine adjustment of the position of the differential pressure core. This solution can provide higher accuracy, but due to its complex mechanical structure and high cost, it is not suitable for all production environments. In addition, there is also a method of using pneumatic components combined with mechanical structures for position adjustment. This method can meet the accuracy requirements to a certain extent and has cost advantages, but its adjustment flexibility is still insufficient. The above-mentioned prior art generally has the problem of poor flexibility when adjusting the position of the differential pressure core, especially when soldering is required on different parts of the differential pressure core, the differential pressure core needs to be rotated and adjusted to a suitable position due to structural limitations.
