Description

Technical Field

[0001] The utility model relates to the technical field of cold bending of glass, in particular to a self-adaptive profiling device for cold bending of glass. Background Art

[0002] Display cover glass for mobile phones and tablets has gone through the development process of 2D, 2.5D and 3D. With the development of new application fields, display glass has gradually developed into the field of automotive glass and automotive curved display touch glass. However, automotive glass and automotive curved display touch glass are mostly curved glass with a large area. The traditional 3D hot bending forming process of mobile phones and tablets cannot meet the needs of automotive glass and automotive curved display touch glass. The main problems are that the hot bending forming process cannot achieve ultra-large-sized curved forming, the forming yield is very low and the cost is high, the energy consumption is high, and it is easy to produce optical distortion. Therefore, only "cold bending" technology can be considered to meet the needs of automotive glass and automotive display touch glass.

Since the pressure under the air bag is very low, it can ensure that all position points are evenly stressed, and achieve high forming yield while achieving ultra-large-sized curved surface forming. However, the cost is high and is not conducive to production. Utility Model Content

[0027] Example

[0028] like Figure 1-8As shown, a glass cold bending forming adaptive profiling device includes a profiling fixture 1 and an adaptive unit; wherein the adaptive unit is mainly composed of a plurality of first cylinders 2, a cylindrical component 3, a profile frame 4, a suction cup component 5 and a positioning component 6, and the profiling fixture 1 is arranged directly above the adaptive unit, and its upper end is connected to an external telescopic device to realize the vertical up and down movement of the profiling fixture 1, and cooperate with the adaptive unit to perform cold bending on the glass.

[0029] The lower end surface of the profiling jig 1 is arranged in an arc-shaped structure, and an adsorption area is arranged along the length direction of the lower end surface, and the adsorption area includes a central suction cup 11 and an edge suction cup 12, and a plurality of side suction cups 13 arranged on the central suction cup 11 and the edge suction cup 12, and a surface suction vacuum groove 14 is arranged between the plurality of side suction cups 13, and a suction cup vacuum connecting groove 15 is opened on one side of the profiling jig 1, and a surface suction vacuum connecting groove 16 is arranged in the suction cup vacuum connecting groove 15. When the entire profiling action begins, the external telescopic device is started to drive the profiling jig 1 to move downward. The central suction cup 11 located in the middle of the lower end surface first contacts the glass and establishes a vacuum. The displacement of the glass is suppressed by the vacuum establishment. As the profiling jig 1 moves further downward, the suction cups 13 on both sides and the edge suction cups 12 contact the glass and establish a vacuum. At this time, the cold-bent glass is completely in contact with the profiling jig. At this time, the surface suction vacuum groove 14 is opened to increase the contact force between the glass and the profiling jig 1 to prevent rebound. After maintaining this position for several seconds, the profiling jig moves upward with the cold-bent glass to complete the cold bending action.

[0030] The profile frame 4 provides support for the device, including a support base 41, a fixed base plate 42, six brackets 43 and four corner pieces 44; the support base 41 and the fixed base plate 42 are both arranged in a rectangular structure, and are connected and fixed to the machine for forming operations through the support base 41. The fixed base plate 42 is fixedly installed on the support base 41. The six brackets 43 are respectively fixed to the four corners of the upper end surface of the fixed base plate 42 and the middle edge in the length direction. The four corner pieces 44 are respectively fixedly connected between the brackets 43 at the four corners, and the corner pieces 44 are located at the top of the brackets 43. At the same time, a reinforcement piece 45 is also provided between the lower end of the bracket 43 and the fixed base plate 42 to improve the connection stability of the device.

[0031] A plurality of first cylinders 2 are arranged on the top of the fixed base plate 42 and are arranged along the length direction of the fixed base plate 42. A plurality of first cylinders 2 adopt a constant cylinder diameter to ensure that the reaction force always remains constant, that is, the pressure at each position point is the same when the glass is fixed on the adaptive unit; the cylindrical component 3 is fixedly installed on the output end of the first cylinder 2 and forms a line contact with the glass surface for cold bending forming. The cylindrical component 3 includes a mounting seat 31, a main shaft 32 and a roller 33. The number of mounting seats 31 is the same as the number of first cylinders 2. A pair of through holes are opened on both sides of the top of the mounting seat 31. The two ends of the main shaft 32 are installed in the through holes to form a fixation. The roller 33 is made of anti-static silicone material and is sleeved on the main shaft 32. ; Rubber pads 21 of the same size are installed between adjacent first cylinders 2 to fix them to each other, so as to improve reliable connection and stability, and help to reduce shock and balance pressure, so as to ensure that each first cylinder 2 maintains a good cooperative working state during operation; at the same time, a locking piece 22 is fixedly installed on both sides of a plurality of first cylinders 2, which is made of profiles, and the plurality of first cylinders 2 are connected and fixed by the locking piece 22, so as to provide additional support and fixation for the first cylinder 2, effectively preventing the first cylinder 2 from loosening or displacement during operation, and the double fixation of the rubber pad 21 and the locking piece 22 ensures the reliability of the first cylinder 2 and the cylindrical assembly 3 in operation, thereby improving the working efficiency and precision of the device.

[0032] The suction cup assembly 5 is arranged on both sides of the middle first cylinder 2, including two second cylinders 51, a support plate 52 fixedly installed on the output shaft of the second cylinder 51, and a suction cup 53; the two second cylinders 51 are respectively located between the two first cylinders 2, and the bottom is connected and fixed to the fixed bottom plate 42, and a pair of waist-shaped holes 521 are respectively opened at both ends of the top of the support plate 52. The suction cup 53 is fixedly installed in the waist-shaped hole 521 by bolts, and is adsorbed on the glass surface by generating a vacuum to prevent the glass from shifting in position during the cold bending process.

[0033] The positioning assembly 6 is arranged at the top of the two end corner pieces 44, corresponding to the two outermost first cylinders 2 respectively, and includes four pairs of mounting bases 61, a guide rod 62 arranged on one end of the mounting base 61 close to the first cylinder 2, and a positioning PIN 63 installed on the top of the guide rod 62. Through the precise design and installation of the positioning assembly 6, the accurate positioning of the profiling jig 1 in the device is ensured to support and assist the glass operation during the cold bending process.

[0034] In the active operation mode, the upper profiling jig 1 and the positioning assembly 6 are first accurately positioned. At this time, the first cylinders 2 are all in a retracted state. The operator places the glass on the roller 33 and fixes the glass with the suction cup assembly 5. The operator can activate and raise all the first cylinders 2 according to the preset parameters. The upper surface of the glass is bent under the joint action of the first cylinder 2 and the profiling jig 1. Under the coordinated work and precise control of the first cylinders 2, the glass can perform a curved stroke according to the expected shape requirements; in the passive operation mode, the first cylinders 2 are all in an extended state. The operator places the glass on the roller 33 and fixes the glass with the suction cup assembly 5. After the upper profiling jig 1 is accurately positioned with the positioning assembly 6, the upper profiling jig 1 applies pressure downward to achieve the bending of the glass. This process does not require the operator's active intervention, but relies on the automatic operation of the internal mechanism of the device.
