The lifting suction cup 9 is flush with the surface of the rectangular lifting air suction plate 5 in the reset state, and protrudes toward the surface of the rectangular lifting air suction plate 5 under the drive of the sheet breaking and retracting mechanism, thereby causing the adsorbed AG glass 2 to be broken along the cutting line, and placing the broken AG glass 2 on the conveyor belt to complete the sheet breaking and loading of the AG glass 2; Air suction holes 10 are provided on the surfaces of several rectangular lifting air suction plates 5 and lifting suction cups 9. The air suction holes 10 on the rectangular lifting air suction plates 5 and the lifting suction cups 9 are respectively connected to independent air suction pumps through pipelines, thereby completing the adsorption of the AG glass 2 as a whole and the AG glass 2 after breaking.

[0019] In this embodiment, the loading adsorption seat 1 is installed on the robot arm, and the loading adsorption seat 1 is pulled by the robot arm to move and adsorb the AG glass 2. At the same time, a photoelectric positioning device is also provided on the loading adsorption seat 1 to ensure that the AG glass 2 can accurately enter the air suction cutting area. The air suction cutting area is composed of a frame cutting area 3 and a substrate cutting area 4, wherein the frame cutting area 3 is used to cut the corner waste of the whole AG glass 2, and the AG glass 2 in the substrate cutting area 4 is equally divided into several structures, and the space between adjacent rectangular lifting air suction plates 5 and the frame cutting area 3 and the adjacent rectangular lifting air suction plates 5 are The gaps between the suction plates 5 form criss-cross cutting grooves 6, in which a cutting head 7 is arranged for translational sliding, and a cutting line is formed by the cutting head 7 against the surface of the AG glass 2, and an external force is applied to cause the AG glass 2 to break along the cutting line, wherein an air jet hole 8 is arranged on the loading adsorption seat 1 where the frame cutting area 3 is located, and the air jet hole 8 is connected to an external air pump device through a pipeline, and air is sprayed toward the surface of the AG glass 2 through the air jet hole 8, so as to cause the AG glass 2 in the frame cutting area 3 to break and fall off along the cutting line, and for the AG glass located on the rectangular lifting air suction plate 5, the air jet hole 8 is connected to the external air pump device through a pipeline, and the air jet hole 8 is used to spray air to the surface of the AG glass 2, so as to cause the AG glass 2 in the frame cutting area 3 to break and fall off along the cutting line. By extending and retracting the lifting suction cup 9 provided in the rectangular lifting air suction plate 5, the glass thereon is broken into pieces. Air suction holes 10 are provided on the surfaces of the rectangular lifting air suction plates 5 and the lifting suction cups 9. The air suction holes 10 on the rectangular lifting air suction plates 5 and the lifting suction cups 9 are respectively connected to independent air suction pumps through pipelines, thereby completing the adsorption of the AG glass 2 as a whole and the AG glass 2 after breaking. The significance of such a setting is that the adsorption state of the rectangular lifting air suction plates 5 and the lifting suction cups 9 can be independently controlled. For example, when it is necessary to break the rectangular lifting air suction plates 5, the corresponding air suction pump is controlled to stop working so as to The lifting air suction plate 5 at the breaking position no longer adsorbs the AG glass 2, while the adjacent AG glass 2 is still in the adsorption state of the air suction hole 10 set on the lifting air suction plate 5. At this time, the lifting suction cup 9 at the breaking position keeps adsorbing the glass at that location, and extends outward under the push of the breaking telescopic mechanism to prompt the glass at that location to be broken along the cutting line. After the breaking is completed, the AG glass 2 is still adsorbed on the lifting suction cup 9, and the AG glass 2 is aligned with the conveyor belt and released on the conveyor belt by releasing the adsorption, thereby completing the breaking operation. For the specific breaking process, please refer to the attached manual. Figure 4 The order of the breaking process is to first break the corner AG glass 2, and then break along the entire row of the remaining AG glass 2, refer to the attached manual Figure 4 Middle view, after the whole row of AG glass 2 is broken, break the pieces one by one from one end of the row to the other end, so as to complete the breaking of the whole row, and then repeat the process of breaking the whole row. Figure 4 The operation in the middle view is to break the next row of glass until all the glass is broken. Embodiment 2:

[0020] The lifting mechanism that drives the rectangular lifting air suction plate 5 to perform lifting movement serves as the first-level lifting mechanism, and the sheet-breaking telescopic mechanism that drives the lifting suction cup 9 to perform sheet-breaking movement serves as the second-level lifting mechanism. Both the first-level lifting mechanism and the second-level lifting mechanism are electric hydraulic telescopic cylinders 11. The first-level lifting mechanism and the second-level lifting mechanism work sequentially under the control of the built-in main control MCU of the loading adsorption seat 1.

[0021] In this embodiment, in order to ensure that adjacent glasses do not suffer contact damage during the breaking process, a two-stage telescopic mechanism is provided, wherein the telescopic movement of the rectangular lifting air suction plate 5 serves as the first stage, and on this basis, the outward telescopic movement of the lifting suction cup 9 serves as the second stage. The significance of this arrangement is that after the glass on the rectangular lifting air suction plate 5 is broken, the rectangular lifting air suction plate 5 is telescoped to form a gradient difference between the entire row of broken glasses and the rest of the rows, and the lifting suction cup 9 is extended outward again based on the gradient difference, thereby ensuring that in the process of breaking the entire row one by one, there will be no interference with the rest of the unbroken glasses, thereby ensuring the quality of the glass. Embodiment three:

[0022] The traction mechanism for pulling the cutting head 7 to move includes a transverse cutting device and a longitudinal cutting device. The cutting heads 7 of the transverse cutting device and the longitudinal cutting device are fixedly installed at the bottom of the translation slider 12. The cutting line is formed by pressing the cutting head 7 against the surface of the AG glass 2 and sliding it translationally.

[0023] The translation slider 12 of the transverse cutting device is slidably set in the transverse slide groove 14 opened on the side of the rectangular lifting air suction plate 5. Sliding gears 15 are also installed on both sides of the translation slider 12 of the transverse cutting device. The sliding gears 15 cooperate with the tooth grooves opened in the transverse slide groove 14. The sliding gears 15 are fixedly connected to the driving shaft of the driving motor 16. The rotation of the sliding gear 15 drives the translation slider 12 to translate and slide in the transverse slide groove 14. The driving motor 16 is powered by the wire connected to one side of the translation slider 12.

[0024] The translation slider 12 of the longitudinal cutting device is slidably arranged in the longitudinal slide groove 17 opened on the side of the rectangular lifting air suction plate 5. Both sides of the translation slider 12 of the longitudinal cutting device are connected with traction ropes 18. The traction ropes 18 on both sides are respectively wound around the corresponding winding drums 19 at one end away from the translation slider 12. The winding drum 19 is also fixedly connected to the driving shaft of the winding motor 20. The rotation of the winding motor 20 drives the traction rope 18 to be wound and unwound, thereby pulling the translation slider 12 to perform reciprocating translation sliding.

[0025] In this embodiment, the specific structures of the transverse cutting device and the longitudinal cutting device are further disclosed, wherein the longitudinal cutting device adopts a method of setting traction ropes 18 at both ends to perform reciprocating translational sliding, but on this basis, the transverse cutting device can no longer reciprocate through the above structure, which will cause interference in the longitudinal and transverse directions, and thus the normal cutting steps cannot be completed. For this reason, the transverse cutting device is driven by the rotation of the sliding gear 15, and a wire is set on one side. The purpose of this is to enable the transverse translation slider 12 to leave the moving path of the longitudinal cutting device after completing the cutting, thereby ensuring the normal progress of the cutting process. Embodiment 4:

[0026] The loading adsorption seat 1 is located outside the air suction cutting area and is also provided with a receiving groove for accommodating the translation slider 12 of the horizontal cutting device and the longitudinal cutting device. The translation slider 12 enters the receiving groove after the cutting is completed.

[0027] In this embodiment, since the rectangular lifting air suction plate 5 needs to be extended and retracted during the sheet breaking process, the transverse slide groove 14 and the longitudinal slide groove 17 opened on the side of the rectangular lifting air suction plate 5 will be misaligned. If the translation slider 12 is not moved out at this time, the extension and retraction of the rectangular lifting air suction plate 5 will not be able to proceed normally. In this context, the loading adsorption seat 1 is located outside the air suction cutting area and is also provided with a accommodating groove for accommodating the translation slider 12 of the transverse cutting device and the longitudinal cutting device. The translation slider 12 enters the accommodating groove after the cutting is completed, so as not to affect the subsequent sheet breaking process.

[0028] A feeding method for an AG glass production line, using the above-mentioned feeding device for an AG glass production line, comprises the following steps: Step 1: Move the loading adsorption seat 1 to the stacking position of the AG glass 2 by the robotic arm, so that the surface of the loading adsorption seat 1 is attached to the surface of the AG glass 2, and start the air suction pump to adsorb the AG glass 2, and lift it upward under the movement of the robotic arm; Step 2: Forming a cutting line on the surface of the AG glass 2 by translational movement of the cutting head 7 in the cutting groove 6; Step 3: Pumping air into the air jet hole 8 of the frame cutting area 3 causes the AG glass 2 corners in the frame cutting area 3 to fall off, and this process is carried out with a waste receiving box placed below; Step 4: Drive the whole row of sheet-breaking and retracting mechanisms on the side of the substrate cutting area 4 to work synchronously, so that the whole row of AG glass 2 is separated along the cutting line direction. After the whole row of sheet-breaking is completed, the rectangular lifting air suction plate 5 of the whole row protrudes from the surface of the loading adsorption seat 1 under the drive of the lifting mechanism. At this time, the sheet-breaking and retracting mechanisms of the whole row are synchronously retreated, so that the whole row of AG glass 2 after sheet-breaking is adsorbed again with the protruding rectangular lifting air suction plate 5; Step 5: Then the lifting suction cups 9 of the whole row sequentially protrude from one end to the other end of the rectangular lifting air suction plate 5 for the second time, thereby completing the sequential breaking operation, and the broken AG glass 2 is released onto the conveyor belt; Step 6: Repeat steps 4 and 5 to sequentially complete the breaking operation of other entire rows of AG glass 2 until the breaking operation of all parts is finally completed.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
