TECHNICAL FIELD

[0001] The utility model relates to a glass carrying device, in particular to a vacuum adsorption glass carrying device. BACKGROUND

[0002] Glass is a multifunctional material, widely used in daily life, construction, technology, art and other fields. For example, tempered glass is widely used in building windows and glass curtain walls to provide lighting and aesthetic effect; float glass and laminated glass are used in automobile windshields and windows to provide clear vision and safety; optical glass is used in telescopes, camera lenses and other precision instruments to ensure high definition and accuracy. These glasses are often made by cutting method, that is, using a whole piece of glass to form various shaped glasses by cutting, and a carrying device is needed to carry the whole piece of glass during the manufacturing process to avoid safety accidents.

[0049] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0050] Please refer to Figures 1-7 As an embodiment of the present application, the glass conveying device of vacuum adsorption comprises a frame 1.

[0051] A first telescopic section 8 is arranged on the frame 1, and a second telescopic section 12 is arranged in the first telescopic section 8 in a sliding manner; a first lifting section 13 is fixedly installed on the second telescopic section 12; a second lifting section 15 is slidably embedded on the first lifting section 13; and a connecting piece 16 is fixedly installed on the second lifting section 15.

[0052] A plurality of third telescopic sections 17 are fixedly installed on the connecting member 16 and are equidistantly distributed along the circumference of the connecting member 16; a fourth telescopic section 18 is slidably fitted on the third telescopic section 17; and a suction disc 19 is fixedly installed on the fourth telescopic section 18;

[0053] The vehicle frame 1 is provided with a lengthening structure and an expanding structure which cooperate with each other; the lengthening structure can drive the second telescopic section 12 to slide inwards or outwards on the first telescopic section 8; and the expanding structure can drive the fourth telescopic section 18 to slide inwards or outwards on the third telescopic section 17.

[0054] The vehicle frame 1 is further provided with a swing arm structure which can drive the first telescopic section 8 to swing and always be parallel to the vehicle frame 1.

[0055] In this embodiment, the vehicle frame 1 is moved to the vicinity of the glass stacking area, and the vehicle frame 1 is always not in contact with the glass stack, so as to avoid the vehicle frame 1 from contacting the glass and causing the glass position to deviate or even break.

[0056] The first telescopic section 8 is driven by the swing arm structure to swing in parallel, so as to swing the first telescopic section 8 above the glass, thereby facilitating the subsequent adsorption of the glass.

[0057] According to the size of the glass, the second telescopic section 12 is driven by the lengthening structure to slide outwards or inwards in the first telescopic section 8, so as to drive the connecting member 16 to move synchronously, thereby moving the connecting member 16 to the middle part of the glass; at the same time, the fourth telescopic section 18 is driven by the expanding structure to slide inwards or outwards in the third telescopic section 17, so as to drive the suction disc 19 to approach or move away from the connecting member 16, thereby changing the contact point position of the suction disc 19 and the glass, so as to ensure that the adsorption range of each suction disc 19 on the glass is maximum, thereby ensuring the adsorption force of the glass.

[0058] The suction disc 19 is provided with a vacuum system connection, the second lifting section 15 is driven to slide outwards on the first lifting section 13, so that the suction disc 19 is in close contact with the glass; then the vacuum system will extract the air in the suction disc 19, so that the suction disc 19 is tightly adsorbed on the glass; and when the glass is transported, the vacuum system will re-inject air into the suction disc 19, so as to contact the adsorption state of the suction disc 19.

[0059] According to the size of the glass, the connecting piece 16 is moved by the extension structure, the connecting piece 16 is located in the middle of the glass, the larger the size of the glass is, the greater the moving distance of the connecting piece 16 is; and the suction cups 19 are driven away from the connecting piece 16 by the expansion structure, so that the suction contact between the suction cups 19 is increased, and the suction force of the suction cups 19 on the glass is increased; the glass is prevented from being separated during the glass carrying process due to the small distance between the suction cups 19 caused by the large size of the glass or the large distance between the suction cups 19 caused by the small size of the glass, so that the safety of the carrying device is improved.

[0060] As a further scheme of the utility model, the swing arm structure includes a first swing arm 6 and a second swing arm 7 rotatably installed on the frame 1, the first swing arm 6 and the second swing arm 7 are parallel to each other, and the first swing arm 6 and the second swing arm 7 are both rotatably installed on the first telescopic joint 8; the frame 1 is fixedly installed with a swing arm motor 2; the swing arm motor 2 is fixedly installed with a swing arm screw rod column 3 on the output end; the swing arm screw rod column 3 is threadedly connected with a swing arm threaded sleeve 4; the swing arm threaded sleeve 4 is rotatably installed with a connecting rod 5 rotatably connected with the first swing arm 6.

[0061] In this embodiment, when the swing arm motor 2 operates, it can drive the swing arm screw rod column 3 to rotate, and drive the swing arm threaded sleeve 4 to move along the length direction of the swing arm screw rod column 3 through thread cooperation, so as to drive the first swing arm 6 to rotate close to or away from the frame 1 through the connecting rod 5, and the included angles of the connecting rod 5, the first swing arm 6 and the swing arm threaded sleeve 4 are changed in this process.

[0062] When the first swing arm 6 rotates, it can drive the second swing arm 7 to swing synchronously through the first telescopic joint 8; a parallelogram structure is formed between the first swing arm 6, the second swing arm 7, the frame 1 and the first telescopic joint 8, wherein the first swing arm 6 and the second swing arm 7 are parallel to each other, and the frame 1 and the first telescopic joint 8 are parallel to each other, so that when the first swing arm 6 rotates, it can drive the first telescopic joint 8 to move parallel to the frame 1, so that the connecting piece 16 always remains parallel to the frame 1, so as to ensure that the suction cups 19 can parallelly adsorb the glass, and avoid that the suction cups 19 and the glass have an inclined angle, so as to ensure that the glass can be safely carried.

[0063] The swing arm structure can ensure that the glass always remains parallel to the ground (the frame 1) during the glass carrying process, so as to avoid that the glass slides sideways due to gravity and shaking during the carrying process, and improve the safety of the device; and the thread cooperation can ensure that the position of the glass on the frame 1 remains fixed during the carrying process, so as to avoid that the glass is damaged.

[0067] Through the extension structure, the connecting piece 16 is moved to the middle part of the glass, so that the suction force of the suction cup 19 for adsorbing the glass can be evenly distributed on the glass, thereby avoiding uneven stress and unstable adsorption, so as to ensure that the glass will not fall or break during the carrying process.

[0071] The second lifting section 15 is driven by the air cylinder 14 to slide outward on the first lifting section 13, so as to shorten the distance between the glass and the connecting piece 16, so that the suction cup 19 can contact the glass; then through the cooperation with the central control system, the air in the suction cup 19 is extracted through the vacuum system, so that the suction cup 19 tightly adsorbs the glass, and the distance between the suction cup 19 and the glass is adjusted through the air cylinder 14 in the process, so as to avoid unstable adsorption, thereby improving the success rate of carrying.

[0072] As a further scheme of the utility model, the expansion structure comprises an expansion screw rod column 22 rotatably installed on the third telescopic section 17; the expansion screw rod column 22 is fixedly installed with a fourth bevel gear 2201 engaged with the third bevel gear 2101; the fourth telescopic section 18 is fixedly installed with an expansion threaded sleeve 23 engaged with the expansion screw rod column 22.
