Detailed Description
The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.
Referring to fig. 1 to 3, the vacuum box locking mechanism for decorating film coating comprises a vacuum box 1 and a workbench surface 2, wherein the bottom of the vacuum box 1 is open and used for extending a workpiece, a plurality of guide rods 3 are arranged at intervals in the middle of the bottom end surface of the vacuum box 1, two sides of each guide rod 3 are respectively provided with an air bag ring 4, the top of each air bag ring 4 is hermetically bonded with the bottom end surface of the vacuum box 1, and the side edge of each air bag ring 4 is not bonded with the corresponding guide rod 3; the air bag ring 4 is made of heat-resistant rubber and has certain elasticity, such as butyl rubber, the cross section of the air bag ring 4 is rectangular, and the air bag ring 4 is filled with air with standard atmospheric pressure, namely the interior of the air bag ring is the standard atmospheric pressure when the air bag ring is not deformed. A circle of grooves 5 are formed in the periphery of the top of the working table surface 2, the width of each groove 5 is just equal to the distance between two separated side edges of the two air bag rings 4, so that the air bag rings 4 can be just embedded, and guide holes 6 which correspond to the guide rods 3 one by one are formed in the middle positions in the grooves 5; the guide rod 3 is integrally formed by a cylindrical rod and an inverted-truncated-cone-shaped rod, the guide hole 6 is formed by a cylindrical hole and an inverted-truncated-cone-shaped hole, the diameter of the cylindrical hole is equal to that of the cylindrical rod, the guide accuracy is guaranteed, and a vertical groove (not shown in the figure) is formed in the side wall of the cylindrical rod and used for ventilation when the guide rod is inserted; the length of the cylindrical hole is smaller than that of the cylindrical rod, and the size of the inverted truncated cone-shaped hole is completely consistent with that of the inverted truncated cone-shaped rod.
Referring again specifically to fig. 4, during insertion of the guide rod 3 into the guide hole 6, the bottom of the air bag loop 4 just reaches the notch height of the groove 5 when the bottom of the cylindrical rod just touches the top of the cylindrical hole. The design is so that before the position adjustment is completed (when the bottom of the cylindrical rod is not contacted with the top of the cylindrical hole), slight position deviation possibly exists between the working table surface 2 and the vacuum box 1, the air bag ring 4 cannot be contacted with the groove 5 in the process, the phenomenon that the air bag ring 4 is extruded by the groove 5 along the groove edge due to the position deviation is avoided, and the air bag ring 4 is prevented from being crushed and damaged.
As shown in fig. 5, in the film coating operation, the work table 2 on which the workpiece is placed is first raised to abut against the bottom of the vacuum chamber 1. During butt joint, in the process that the guide rod 3 is inserted into the guide hole 6, the inverted circular truncated cone-shaped rod can ensure that the guide rod 3 can be smoothly inserted into the guide hole 6 under the condition that certain deviation (generally within 1-2 mm) occurs in position, and the matching structure can realize the function of adjusting the position and ensure that the vacuum box 1 is accurately butted with the working table top 2; when the guide rods 3 are completely inserted into the guide holes 6 in a one-to-one correspondence mode, the distance between the end face of the bottom of the vacuum box 1 and the bottom of the groove 5 is smaller than the upper thickness and the lower thickness of the air bag ring 4, the air bag ring 4 is embedded into the groove 5 and is extruded and deformed, and the outer side of the air bag ring 4 is blocked by the groove 5 during deformation, so that the air bag ring 4 can only deform and protrude into gaps between the adjacent guide rods 3. The air bag ring 4 after extrusion deformation can effectively completely seal the gap between the end surface of the bottom of the vacuum box 1 and the working table surface 2, and cannot be affected by the unevenness of the butt joint surface.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
