Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0049] In the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0050] The utility model provides an embodiment of a pressing and positioning device for an ultra-thin film flexible workpiece, which can be used to press and position the ultra-thin film, not only firmly pressing and positioning, but also ensuring that the ultra-thin film product is smooth during the pressing process without being damaged.

[0051] The clamping and positioning device for ultra-thin film soft workpieces includes:

[0052] The load-bearing platform is a load-bearing machine platform, which is used to play the main load-bearing and supporting role.

[0053] A carrying glass 100 is arranged on the carrying platform, and the carrying glass 100 is mainly used to prevent ultra-thin film products.

[0054] The pressure plate module includes:

[0055] When setting up the glass pressing plate 210, the glass pressing plate 210 is selected to have high strength and high flatness to ensure that the structure of the entire pressing and positioning device is stable and durable, and the pressing flatness of the ultra-thin film is good.

[0056] and a glass frame 220 connected around the glass pressing plate 210;

[0057] The glass pressing plate 210 is fixedly mounted on the glass frame 220. To ensure the flatness of the ultra-thin film product pressed by the glass pressing plate 210, the bottom surface of the glass pressing plate 210 is set to be flush with the bottom surface of the glass frame 220.

[0058] In some embodiments of the present application, the glass frame 220 includes:

[0059] The first frame plate is provided with two pieces, which are arranged relatively parallel;

[0060] The first frame plate has first concave portions formed at the top surfaces of both ends thereof, and second concave portions formed at the bottom surface thereof.

[0061] The second frame plate is provided with two pieces, and the two ends thereof are respectively placed on the first recessed part and are locked and fixed to the first frame plate by screws.

[0062] The glass pressing plate 210 is inserted into the second recessed portion and is bonded and fixed to the first frame plate by glue.

[0063] In some embodiments of the present application, a lifting handle 900 is provided on the glass frame 220 , and the lifting handle 900 can facilitate the user to lift the glass frame 220 and the glass pressing plate 210 to place the product.

[0064] The lifting handle 900 is arranged on one of the first frame plates.

[0065] A connecting base 300, assembled and fixed on the bearing platform;

[0066] The connection base 300 is a connection substrate, which is arranged to extend along the length of the second frame plate and is fixed on the supporting platform by screws.

[0067] A rotating connection module, connected to the connection base 300 and one side of the glass frame 220 respectively, for enabling the glass frame 220 to rotate relative to the connection base 300;

[0068] In some embodiments of the present application, the rotating connection module includes:

[0069] Rotating connecting member 630;

[0070] The adapter component 620 is fixedly mounted on one side of the glass frame 220 and is rotatably connected to the rotatable connector 630;

[0071] The connection base 300 is arranged at one side of the rotational connection and is rotationally connected to the rotational connection member 630 .

[0072] The nitrogen buffer pressure rod 400 has one end rotatably connected to the connection base 300 and another end rotatably connected to the rotation connection module.

[0073] Specifically, one end of the nitrogen buffer pressure rod 400 is rotatably connected to the connection base 300 , and the other end is rotatably connected to the adapter component 620 .

[0074] When the ultra-thin film product needs to be pressed and positioned, the lifting handle 900 can be pulled by hand, and the lifting handle 900 drives the glass frame 220, the glass pressing plate 210, and the adapter component 620 fixedly connected to the glass frame 220 to rotate relative to the rotating connection member 630, and the rotating connection member 630 rotates relative to the connecting base 300;

[0075] At the same time, since one end of the nitrogen buffer pressure rod 400 is rotatably connected to the adapter component 620, and the other end is rotatably connected to the connecting base 300, when the adapter component 620 is driven to move upward, the nitrogen buffer pressure rod 400 is also driven to move. When specifically connected, the nitrogen buffer pressure rod 400 includes a cylinder body and a rod body connected to the cylinder body, the cylinder body is rotatably connected to the connecting base 300, and the rod body is rotatably connected to the adapter component 620.

[0076] When the adapter component 620 moves upward, the rod body is driven to contract relative to the lever body.

[0077] At this time, the glass pressing plate 210 is in a state of being opened at a certain angle, and the ultra-thin film product can be placed on the supporting glass 100, and then the glass frame 220 and the glass pressing plate 210 are pulled downward, and the glass frame 220 and the glass pressing plate 210 rotate relative to the rotating connecting member 630, and the rotating connecting member 630 rotates relative to the connecting base 300, and the rod body of the nitrogen buffer pressure rod 400 is continuously pulled out. Due to the buffering effect of the nitrogen buffer pressure rod 400, the glass pressing plate 210 and the glass frame 220 structure can move down slowly and smoothly when moving downward, and finally smoothly pressed onto the ultra-thin film product on the supporting glass 100, ensuring the stability and damage-free pressing of the ultra-thin film, and will not cause damage to the ultra-thin film product or poor flatness due to rapid pressing down on the ultra-thin film product, thereby ensuring the accuracy of later detection of the ultra-thin film product in this clamping and positioning device.

[0078] In order to make the glass pressing plate 210 fall as smoothly as possible, a rotating connection module and a nitrogen buffer pressure rod 400 structure can be set on both sides of the glass frame 220 during the setting. The nitrogen buffer pressure rod structure can directly adopt the existing technical structure and will not be elaborated here.

[0079] In some embodiments of the present application, an elastic component 500 is further included. The elastic component 500 is arranged at the bottom surface of the glass frame 220. The elastic component 500 mainly plays a buffering role during the pressing process of the glass frame 220 and the glass pressing plate 210.

[0080] When the glass frame 220 and the glass pressing plate 210 are pulled down, the glass pressing plate 210 keeps approaching the ultra-thin film. Since the ultra-thin film is extremely thin, if the glass pressing plate 210 is directly pressed down to contact the ultra-thin film, the force above it will be directly applied to the ultra-thin film, which may cause damage to the ultra-thin film or change in flatness. By setting the elastic component 500, during the downward movement of the glass pressing plate 210, the elastic component 500 will first contact the supporting glass 100 to provide an elastic buffer force, so that the glass pressing plate 210 can finally be pressed smoothly on the ultra-thin mold to avoid damage to the ultra-thin film and ensure the flatness of the ultra-thin film that is pressed and positioned.

[0081] In addition, the provision of the elastic component 500 can also prevent the glass pressing plate 210 and the carrying glass 100 from contacting and being damaged.

[0082] In some embodiments of the present application, the elastic component 500 is an elastic sponge with a thickness of 50um-1000um.

[0083] In some embodiments of the present application, a base connecting portion 310 is formed at the end of the connecting base 300 , and a first passing portion 311 is formed on the base connecting portion 310 ; the first passing portion 311 is a first passing hole.

[0084] The adapter component 620 is clamped on one side of the glass frame 220 and extends along the length direction of the glass frame 220, and includes an extension portion 621 extending beyond the end of the glass frame 220, and is arranged opposite to the base connecting portion 310, and a second through portion 622 is arranged on the extension portion 621;

[0085] The adapter component 620 is an adapter connecting plate, which is clamped on the side of the glass frame 220 and locked and fixed with the glass frame 220.

[0086] One end of the transition component 620 is connected to the middle position of the glass frame 220 , and the other end extends outward.

[0087] The extending portion 621 is an extending end, and a second passing portion 622 is disposed above the extending portion 621 , and the second passing portion 622 is a second passing hole.

[0088] A rotating connecting member 630 is arranged between the protruding portion 621 and the base connecting portion 310, and a first rotating bearing 710 and a second rotating bearing 720 are arranged in the rotating connecting member 630;

[0089] The rotating connection member 630 is a rotating connection block, and the first rotating bearing 710 and the second rotating bearing 720 are arranged along the length direction thereof.

[0090] A first insertion pin 730 passes through the first passing portion 311 and is inserted into the first rotating bearing 710;

[0091] The second insertion pin 740 passes through the second penetration portion 622 and is inserted into the second rotating bearing 720 .

[0092] The first insertion pin 730 and the first through portion 311 are interference fit, and are assembled in the inner ring of the first rotating bearing 710;

[0093] The second insertion pin 740 and the second penetration portion 622 are interference-fitted, and are assembled in the inner ring of the second rotating bearing 720 .

[0094] In this way, when the glass frame 220 is lifted, the adapter component 620 can rotate relative to the rotating connector 630 , and the rotating connector 630 can rotate relative to the connecting base 300 to achieve the opening and closing of the glass frame 220 and the glass pressing plate 210 .

[0095] The maximum opening and closing angle between the glass pressing plate 210 and the supporting platform is 45°. When the glass pressing plate 210 is opened, the end portion is used to make the glass pressing plate 210 shift upward as a whole through the double bearings. Since the adapter component 620 is connected to the rotating connecting member 630, the rotating connection point is at the end position away from the glass frame 220, that is, away from the position of the supporting glass 100, thereby avoiding the friction between the glass pressing plate 210 and the supporting glass 100 during the rotation process to damage the fixture; the glass pressing plate 210 is driven to open by the rotation cooperation of the double bearings, which is also convenient for taking and placing ultra-thin mold products.

[0096] The ultra-thin film flexible workpiece pressing and positioning device in this embodiment is not only simple in structure but also highly safe in operation, and is convenient for taking and placing ultra-thin film products.

[0097] In some embodiments of the present application, the adapter component 620 includes:

[0098] A first adapter plate 623 and a second adapter plate 624 connected to the first adapter plate 623, the second adapter plate 624 is arranged perpendicular to the first adapter plate 623, and a clamping portion clamped on the glass frame 220 is formed therebetween, a locking portion for locking the adapter component 620 to the glass frame 220 is arranged on the first adapter portion, the locking portion is a locking through hole, a threaded hole can be arranged on the glass frame 220, when fixing, a screw is passed through the locking through hole and screwed into the threaded hole.

[0099] In some embodiments of the present application, a first mounting seat 810 is mounted on an end of the adapter component 620 opposite to the extension portion 621, and a first connecting bearing is mounted in the first mounting seat 810;

[0100] A second mounting seat 820 is provided at one end of the connecting base 300 opposite to the base connecting portion 310, and a second connecting bearing is assembled in the second mounting seat 820;

[0101] One end of the nitrogen buffer pressure rod 400 is rotatably connected to the first connecting bearing, and the other end is rotatably connected to the second connecting bearing.

[0102] In some embodiments of the present application, the flatness of the load-bearing glass 100 and the ballast glass is less than or equal to 0.04 mm, and the parallelism of the top surface of the load-bearing glass 100 and the top surface of the ballast glass is -0.04-0.04 mm.

[0103] To ensure that the carrying glass 100 and the ballast glass are set to have a flatness less than 0.04 mm, the flatness of the glass plate used for pressing the ultra-thin mold can be guaranteed, thereby effectively improving the overall flatness of the pressed ultra-thin film.

[0104] The roughness of the supporting glass 100 and the ballast glass is set to be less than 1.6 um, so that the surfaces of the two glass plates can remain smooth. By controlling the surface roughness, reflection and refraction can be avoided, thereby improving the detection accuracy of ultra-thin film products.

[0105] The parallelism between the top surface of the carrier glass 100 and the top surface of the ballast glass is -0.04-0.04 mm to ensure the parallelism of the two, thereby ensuring the flatness of the ultra-thin film pressing.

[0106] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
