Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit board processing, in particular to a clamping device with a turnover structure for printed circuit board processing. Background Art

[0002] Printed circuit boards, also known as printed circuit boards, are the support bodies of electronic components and the providers of electrical connections for electronic components. With the development of science and technology, printed circuit boards have also developed from single-layer to double-sided, multi-layer and flexible, and are still developing. There are many manufacturing processes for printed circuit boards. During the processing, in order to enhance the stability of the printed circuit boards during processing, fixed devices are usually used to clamp the printed circuit boards. However, the existing clamping devices do not have protective devices when clamping the printed circuit boards, which makes it easy for the clamping devices to cause damage when limiting them. There is also no angle limit device when flipping the printed circuit boards, which makes them unstable during processing. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides an embodiment: a clamping device for processing a printed circuit board with a flip structure, comprising a workbench 1, a sliding groove 2 is arranged on the upper surface of the workbench 1, a bidirectional axis motor 3 is fixedly connected to the middle position inside the sliding groove 2, and threaded rods 4 are fixedly connected to the output ends on both sides of the bidirectional axis motor 3. There are two threaded rods 4, and sliding blocks 5 are threadedly connected to the side surfaces of the threaded rods 4. The rotation of the threaded rods 4 can drive the two sliding blocks 5 to move in opposite directions at the same time.

[0024] The upper surface of the sliding block 5 is fixedly connected to a moving seat 6, and the lower surface of the moving seat 6 is slidably connected to the workbench 1. The sliding block 5 drives the moving seat 6 to move, so as to limit different printed circuit boards. The internal rotation of the moving seat 6 is connected to a fixed shaft 7, and the rotating handle 8 can be connected to the limiting seat 9 together. A rotating handle 8 is fixedly connected to one end of the fixed shaft 7. Rotating the rotating handle 8 can drive the limiting seat 9 to flip over as a whole. The end of the fixed shaft 7 away from the rotating handle 8 is fixedly connected to the limiting seat 9, which is convenient for limiting the printed circuit board.

[0025] The upper surface of the limit seat 9 is rotatably connected to the first rotating block 10, and the side surface of the first rotating block 10 is fixedly connected to the first threaded block 11. The side surface of the first threaded block 11 is threadedly connected to the limit seat 9. Rotating the first threaded block 11 can push it down, thereby driving the connecting seat 12 and the airbag 13 to descend, pressing the printed circuit board, and the bottom end of the first threaded block 11 is rotatably connected to the connecting seat 12.

[0026] An airbag 13 is provided on the lower surface of the connecting seat 12, which can provide protection for the printed circuit board when the limit is pressed to avoid damage to the printed circuit board. An air pump 14 is fixedly connected to the upper surface of the limit seat 9, and a connecting hose 15 is fixedly connected to the output end of the air pump 14 to inflate the airbag 13.
