Blister machine table automatic backing plate

Abstract

The invention discloses an automatic base plate for a vacuum forming machine worktable. The automatic base plate comprises a base plate, a plurality of supporting units arranged on the base plate, and at least one manipulation robot, wherein each supporting unit comprises a supporting seat and a supporting rod which is arranged in the supporting seat and can move up and down; the supporting rod can be stopped and supported at a lifting position when the supporting rod moves upwards so as to form a lifting state, and when the supporting rod moves downwards, the supporting rod can be stopped and supported at a descending position so as to form a descending state; the manipulation robot is a movable trolley and comprises a frame, a traveling device, and a lifting device, a positioning device and a controller which are arranged on the frame; the lifting device comprises a lifting frame and a lifting motor; an operation head is arranged on the lifting frame; and the operation head acts on the supporting rod and lift up or put down the supporting rod to an ascending position or a descending position along with the lifting frame. According to the automatic base plate, the state of the supporting units can be actively changed, and the automatic base plate has the advantages of simple structure, light weight and the like.

Description

Technical field [0001] The invention relates to a workbench component of a blister machine, in particular to an automatic pad of the workbench of a blister machine. Background technique [0002] At present, the automatic backing plate of the workbench of the domestic blister machine mainly adopts an imported computer-controlled automatic backing system. A large number of small backing plates with small electromagnetic devices at the bottom are combined into a large backing plate. The computer control system controls each plate during operation. The raising and lowering of each position is controlled one-to-one, and the raised small pad is locally combined to form a working pad that is a certain distance above the worktable, and then the plastic suction process is carried out. Because the control unit of this automatic pad is integrated with the small pad, thousands of control units need to enter the high temperature and high pressure blister furnace in the blister process. The la...

Problems solved by technology

[0004] But the above-mentioned technical scheme also has the following deficiencies: 1. Due to the requirements of the plastic-absorbing process, the working backing plate needs to have a certain indentation relative to the edge of the plate to be processed. The plate to be processed needs to be placed in a suitable position so that all the pressing rods in the middle of the support body within the outline of the plate to be processed can be pressed down by the plate to be processed to achieve locking. If the support body inside is not locked

Rectangular plates can generally find a suitable position, but for L-shaped, arc-shaped and other special-shaped plates, rectangular or special-shaped plates with hollow parts, it is usually difficult to find a suitable position. At this time, this automatic backing plate cannot 2. The plate to be processed usually has a certain warpage, and its bottom surface is not a pure plane, and the locking stroke of this automatic backing plate is very small. For the part whose warping exceeds the locking stroke, the support body will fall. If the working backing plate cannot form a complete support, the board may be broken or the surface may be bent during the blister process. For high-gloss plastic film, even if the surface is bent to a small extent, the board will be scrapped. Therefore, this The automatic backing plate with passive locking is not very practical; 3. This kind of backing plate uses the point contact of steel balls and the hollow rod of the backing plate to withstand the huge pressure in the blister process, and the local pressure is very high, so high-strength materials need to be used to Manufacture, high cost, heavy weight, burdens the movement mechanism of the table top of the blister machine; 4. The control unit of the backing plate needs to enter the high-temperature and high-pressure blister furnace in the blister process, which is stable and reliable for the control system of the entire blister machine Negative impact; 5. The single backing plate is composed of 6 parts. For the work surface of the standard blister machine, the entire backing plate needs 3,486 single backing plates, with a total of 20,916 parts. The manufacturing and assembly are complicated and the maintenance is large.
