Fixing clamp for touch screen processing

Abstract

The invention relates to the technical field of electronic processing equipment, in particular to a fixing clamp for touch screen processing. The fixing clamp firmly adsorbs a workpiece, reduces the displacement phenomenon of the workpiece and improves the use stability. Firstly, the upper end of a workbench is wiped, the workpiece is placed at the upper end of the workbench, a pressing handle ispressed, the pressing handle drives a pressing rod to press down through a hinged point until a dead point clamping device is pressed to a dead point position, and the workpiece is pressed by the pressing rod through a rubber pressing head. The fixing clamp further comprises a vacuum workbench, a vacuum adsorption groove, a vacuum adsorption hole, an air exhaust hole, a rubber cushion block and asealing ring, the vacuum workbench is arranged in the middle of the upper end of the workbench, the upper end of the vacuum workbench is provided with the vacuum adsorption groove, the center of the upper end of the vacuum adsorption groove is provided with the vacuum adsorption hole, the upper end of the vacuum adsorption groove is provided with the rubber cushion block, the sealing ring is installed on the edge of the vacuum adsorption groove, the front end of the workbench is provided with the air exhaust hole, and the air exhaust hole communicates with the vacuum adsorption hole.

[0002] As we all know, the touch screen processing fixture is an auxiliary device used for fixing the touch screen during processing, and it has been widely used in the field of electronic processing equipment; the existing touch screen processing fixture includes a workbench, a fixed base, a bolt , dead point clamping device, pressing handle, pressing rod and rubber pressure head. A fixed base is arranged on the front side of the upper end of the workbench. The bolts are screwed through the fixed base and inserted into the upper end of the workbench. The upper end of the fixed base is tightly attached, and the upper end of the fixed base is provided with a dead point clamping device. The pressing handle and the pressing rod are installed inside the dead point clamping device. There is a hinge point at the intersection of the pressing handle and the pressing rod. When the points are on the same straight line, the dead point clamping device is at the dead point position, the workpiece is clamped, and a rubber pressure head is arranged on the outermost side of the lower end of the pressure rod, and the rubber pressure head is screwed on the pressure rod; the existing touch screen processing fixed fixture uses , firstly wipe the upper end of the workbench clean, then place the workpiece on the upper end of the workbench, then press the handle, which drives the pressure rod down through the hinge point until the clamping device is at the dead point. The rod can be pressed against the workpiece by the rubber pressure head; in the use of the existing touch screen processing fixture, it is found that the one-point pressing fastening method makes the workpiece easy to move, resulting in poor stability in use
