Description

Technical Field

[0001] The invention relates to the technical field of clamping, positioning and lifting devices, and in particular to a clamping, positioning and lifting device for integrated circuit board patches. Background Art

[0002] As we all know, during the patching process of integrated circuit boards, the clamping device can firmly fix the circuit board to prevent it from moving in the horizontal direction. Because the patching operation usually requires the tiny electronic components to be accurately placed on the specified pad position on the circuit board, even a small movement may cause the patch position deviation, thus affecting the performance and quality of the circuit board. The lifting device is used to accurately adjust the height of the integrated circuit board in the vertical direction. During the patching process, different components may require different mounting heights.

[0003] However, most of the existing devices of this type use an overall lifting method to adjust the height of the circuit board. Since the integrated circuit board has a thickness tolerance and is prone to local slight deformation when clamped, it is difficult for the overall lifting method to accurately respond to these local changes. When a local area of ​​the circuit board is concave or convex, the local height cannot be effectively adjusted, resulting in an unstable distance between the patch head and the local area of ​​the circuit board; and the local depression or convexity of the circuit board cannot be adjusted for lateral support, which will also lead to an inability to effectively support the circuit board, thereby affecting the patch accuracy and reliability, and easily causing problems such as poor patch and cold soldering, reducing production efficiency and product quality, and making it difficult to meet production needs.
