Description

Pressure maintaining jig

Technical Field

The utility model relates to a lamination equipment technical field is a pressurize tool particularly.

Background

For the mobile phone middle plate accessory, graphite materials need to be attached to achieve heat dissipation. Traditional pressurize tool mills out the rib pressing structure through CNC directly on the tool to laminate graphite plate and protection film. Referring to fig. 1 and 2, a mobile phone middle plate accessory formed by combining nine accessories is shown, a graphite plate is located in the middle of each accessory, the width of graphite is 0.9MM, the width range of a pressing rib is 0.5MM +/-0.05M, the CNC machining precision is +/-0.02 MM, the hardness of a die material is usually 58-60 degrees, and the machining difficulty is high and the cost is high.

Because the rib pressing height is 0.28MM and the width is 0.5MM, and the tolerance control of the width is + -0.05MM, if the rib pressing height exceeds the tolerance range, other accessories can be crushed during pressing, so that the rib pressing height is scrapped, and the tolerance range required by the rib pressing flatness is 0.005MM, so that the pressing unevenness can be caused to generate gaps or over-pressure die marks can be generated to scrap the product when the tolerance range is exceeded.

Because the tolerance management and control is tighter, the success rate of the jig for manufacturing at one time is lower, and the corners of the rib pressing need to be processed by a special non-standard knife. And when the product is pressed, no buffer exists, so that the product is crushed/overpressured or pressed unevenly to form gaps, the product defect is as high as 40%, and a technician can only grind the surface and repeatedly debug the product. Moreover, because the clamp ribbing is smaller, the upper die and the lower die are attached to each other easily to cause the ribbing damage in use, and if the ribbing damage is caused, the ribbing damage is more complicated to replace, the whole clamp needs to be debugged again or the whole set of clamp needs to be replaced, so that the time waste and the clamp cost are increased. Based on above several points urgent need design a novel pressurize tool.
