[0014] 1. During use, the staff first place the dust-proof sheet and the upper cover into the placement groove, where the upper cover is located at the bottom of the placement groove and the dust-proof sheet is directly above the upper cover. At this time, the staff selects a pressing block that fits the size of the dust-proof sheet and slides this pressing block into the two sliding grooves until it abuts against the rear wall surface of the clamping block. Since the heights on both sides of the pressing block are the same as the height of the sliding grooves, the pressing block is fixed between the two clamping blocks. Then, the staff starts the electric push rod through the PLC controller, and the electric push rod begins to move downward. The moving plate and the pressing block move downward under the action of the electric push rod. During the process where the pressing block contacts the dust-proof sheet and presses down the dust-proof sheet and the upper cover, when the four pressure sensors respectively contact the four limit posts on the same vertical line, at this time, the four pressure sensors will transmit the pressure to the display screen and display it on the display screen. Then, the electric push rod starts to move upward, so that the pressing block is separated from the dust-proof sheet. By setting the PLC controller and the pressure sensors, the precise control of the pressing process of the device can be improved, the automatic operation of the device is realized, and the operation convenience of the device is improved. When the electric push rod stops moving, the staff can pull out the sliding plate from the inside of the box body through the handle. At this time, the staff can take out the pressed upper cover dust-proof sheet. By setting the detachable pressing block, the device can select a pressing block that fits the shape and size of the product, thereby improving the pressing effect of the device and also improving the applicability and utilization rate of the device.
