DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 5 , the utility model provides a technical solution:

[0023] Example 1: A balanced oblique pressure type bubble-eliminating pressing jig includes a pressing jig, which is fixed to the upper end of the mold through a pressing telescopic rod 2. The mold includes a lower mold 1 for accommodating the glass plate and an upper mold 5 for installing the tape. A stepped frame groove 6 is provided through the upper mold 5. The pressing jig includes a jig box 3. A hard rubber plate 13 extending to the outside is obliquely provided in the jig box 3. A foam layer 11 is provided at the upper end of the hard rubber plate 13. The outer contour of the hard rubber plate 13 is located on the outside of the glass plate.

[0024] First, the upper mold 1 and the lower mold 5 are pressed relative to each other to make the tape adhere to the glass plate, and then the jig box 3 is driven to descend so that the hard rubber plate 13 is pressed on the step surface of the step frame groove 6 to avoid the hard rubber plate 13 being directly pressed on the tape and causing its position displacement. At the same time, due to the inclined setting, during the downward pressing process, the hard rubber plate 13 is first pressed on one side of the tape. As the downward pressure continues, the foam layer 11 is pressed, and the inclined surface on the hard rubber plate 13 is continuously pressed on the tape along the inclined direction, thereby achieving the purpose of oblique pressure to drive out bubbles, thereby discharging bubbles after positive bonding and making the combined materials tightly pressed to avoid bulging.

[0025] Example 2: Based on Example 1, a mounting groove 4 is provided on the lower mold 1, and the glass plate is placed in the mounting groove 4. A pair of suction cups 8 for adsorbing and clamping the glass plate are provided on both sides of the mounting groove 4. Pull rods 15 are symmetrically inserted into the inner walls on both sides of the mounting groove 4. The pull rods 15 are elastically installed by a first spring 16, and the ends of the pull rods 15 are connected to the suction cups 8.

[0026] The glass plate is installed and positioned by setting the installation groove 4, and the symmetrically distributed suction cups 8 are used to clamp the two sides of the glass plate. In conjunction with the elastically installed pull rod 15, the elastic clamping of the two sides of the glass plate is achieved to avoid the position displacement of the glass plate under oblique pressure.

[0027] A pair of driving rods 7 for driving the upper mold 5 to rise and fall are provided on the lower mold 1. Rollers for winding and unwinding are symmetrically provided on both sides of the upper mold 5. The tape is wound on the rollers. The step frame groove 6 is provided in the middle of the upper mold 5. The lower ends of the two end portions of the hard rubber plate 13 are facing the step surfaces of the step frame groove 6. A pair of buffer air bags 14 are symmetrically provided on the upper end of the lower mold 1. The upper ends of the buffer air bags 14 are facing the lower end surface of the upper mold 5.

[0028] By providing a buffer airbag 14, the lowering height of the upper mold 5 is buffered to avoid tight adhesion between the tape and the glass plate, so that when the mold is closed, the tape adheres to the glass plate but is not completely adhered. At the same time, during the secondary pressing process, the buffer airbag 14 is used to buffer the downward pressure to avoid excessive extrusion.

[0029] Example 3: On the basis of Example 2, the pressing jig includes an upper adjusting plate 9, the upper end of the foam layer 11 is fixedly bonded to the upper adjusting plate 9, a hinge seat 10 is provided on the inner wall of one side of the jig box 3, one end of the upper adjusting plate 9 is rotatably mounted on the hinge seat 10, an adjusting screw 12 is rotatably inserted into the upper end of the jig box 3, and a support rod 18 elastically mounted by a second spring 17 is provided at the lower end of the jig box 3. The adjusting screw 12 and the support rod 18 are both located on the side away from the hinge seat 10, the lower end of the adjusting screw 12 is pressed onto the upper end surface of the upper adjusting plate 9, and one end of the upper adjusting plate 9 is provided with an extension plate 19 pressed onto the upper end of the support rod 18.

[0030] The upper adjustment plate 9 is rotatably installed by setting a hinge seat 10, and then the rotation and tilt angle of the upper adjustment plate 9 is adjusted under the extrusion of the adjusting screw 12. The lower end of the upper adjustment plate 9 is elastically supported by setting the cooperation of the second spring 17 and the support catch 18, thereby adapting to the rotation angle.

[0031] The lower end of the adjusting screw 12 and the upper end of the support rod 18 are both provided with a rotatably mounted rotating ball. By providing the rotating ball, smooth contact between the lower end of the adjusting screw 12 and the upper end of the support rod 18 and the upper adjusting plate 9 is achieved, so that relative sliding occurs during rotation.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
