Huachuang HC-DL145 type cover opener is a special cover plate for research and development to remove airtight packaged devices (parallel sealing and welding), and can perform rework, quality control or defect analysis of the devices.After opening the lid, the sealing and welding layer of the device base is not damaged, and the surface is smooth.During the entire disassembly process, no dust particles contaminate the device, no vibration and shock, and the size of the device will not be changed. After the lid is removed, the device can be repackaged.In addition, the equipment meets the requirements for the use of ultra-clean workshops.

Structural advantage：

The high-precision imported screw seat and slider are used to build the moving mechanism of the loading platform, and the repeated positioning accuracy can reach ±0.01mm, which can ensure the smooth movement of the tube and shell during the operation of the lid.；

The countertop of the loading platform is a high-precision flat-ground steel countertop with an overall plane accuracy of 0.01mm.At the same time, when the countertop is installed on the mobile platform, the overall plane movement accuracy is adjusted by a special person, and the mobile platform countertop movement plane accuracy is better than ±0.010mm.；

The lifting structure of the tool spindle is realized by a small precision machine tool drag plate, which has extremely high stiffness during the cutting process of the spindle to ensure the smoothness of the spindle cutting to the greatest extent.The minimum adjustment scale is 0.005mm, and at the same time there is a high-precision dial indicator as the display, which can ensure the high precision of opening and adjusting the lid.；

The lifting height range of the spindle is 0-10mm, which can be applied to various shells and tubes and customized corresponding tools.；

The positioning compression screw adopts the latest patented optimized structure, which can ensure that the surface coating will not be contaminated or damaged during the compression of the tube and shell.
Use of technical matters：

To unblock, the four sides need to be unblocked in accordance with the method of “first open the symmetrical long side, then open the symmetrical short side (any symmetrical sides of the square tube and shell are first unblocked)”.When the long side is unsealed, the cutting width shall not exceed “the wall thickness of the tube and shell-0.1mm”, and the remaining 0.1mm shall be the unsealed support to ensure the flatness of the unsealed plane after unsealing (if the weld width exceeds the wall thickness of the tube and shell, it is still necessary to cut the width on the long side to retain the 0.1mm support surface, and then the unsealing needs to be assisted by a utility knife)；

When the smaller product is unsealed and clamped on the long side, because the width of the product is too narrow, the compression head on the top of the lid opener should be pressed down and clamped in the middle of the long side of the product, and the short side is in the middle of the rear (that is, away from the direction of the tool).The reason is that there are processed chamfering at the cutting place of the countertop, and it is easy to tilt the short side direction when the middle part of the smaller tube and shell is pressed down and clamped, resulting in different cutting depths of the long and short sides after cutting, resulting in height differences.；

If the cutting width of the short side of the edge is insufficient, the parameters can be adjusted to re-cut the four sides. Avoid cutting only two short sides.
