Description

Technical Field

[0001] This invention relates to the field of clamping equipment, and in particular to a vacuum suction cup manipulator. Background Technology

[0002] Vacuum suction cup robots are gripping devices based on vacuum adsorption technology used to connect and fix flat objects such as glass. They utilize the negative pressure generated inside the suction cup to tightly adhere to the glass surface, forming a sealed adsorption force, and then the glass is transported and used. Therefore, they are widely used in glass production.

[0003] Chinese patent application number "CN202011218397.3" discloses "a separately controllable vacuum suction cup robot mechanism, including a base, a rotating mechanism mounted on the base, the rotating shaft of the rotating mechanism extending out of the top surface of the base and fixed with a circular rotating plate, and an upper support frame fixed to the top surface of the circular rotating plate." While it achieves the effect of "automatically adsorbing and gripping parts and directly rotating and transporting them to other positions, facilitating subsequent operations on other equipment, which is very convenient," the vacuum suction cup robot's suction cup installation position is generally fixed during use. Therefore, it can only adsorb and connect glass of a fixed size. Adjusting the suction cup position is complex, making it difficult to quickly change the suction cup position and inconvenient for adsorbing and connecting glass of different sizes. The number of suction cups installed is generally fixed. When adsorbing and connecting glass of different weights, only the entire robotic arm can be replaced; the number of suction cups cannot be quickly adjusted, which brings inconvenience to the adsorption and connection of glass of different weights. When adsorbing flat glass and curved glass at different angles, the installation angle of the suction cups is also fixed, and the angle of the suction cups cannot be quickly changed according to the angle of the glass. This means that it cannot be used to adsorb and connect glass of different angles and curved surfaces. At the same time, when adjusting the suction cups, only the position can be adjusted, and the angle and position cannot be adjusted at the same time. Therefore, the robotic arm has a single function and can only be used to handle one type of glass. It cannot be quickly adjusted according to changes in the type of glass and is not suitable for handling different types of glass. Summary of the Invention

[0004] The main objective of this invention is to provide a vacuum suction cup robot that can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

Rotary shaft mounting plates are welded to both the front and rear ends of the central mounting plate. Guide rail connecting shafts are movably mounted on both the front and rear ends of the two rotary shaft mounting plates. The first and second guide rails are fixedly connected to the outer sides of the guide rail connecting shafts. A space is provided between the first and second guide rails.

Multiple suction cup structures are movably mounted on the lower ends of the first and second guide rails, located between the two screw mounting brackets. A rotary drive structure is fixedly mounted on one end of the second guide rail.

[0008] As a further embodiment of the present invention, the angle adjustment structure includes an adjustment motor, an adjustment gear, a first mounting plate, a first rack, a second mounting plate, and a second rack. The adjustment motor is fixedly mounted on the upper end of the central mounting plate, the adjustment gear is fixedly mounted on the rotating shaft end of the adjustment motor, the first mounting plate is fixedly mounted on the upper end of the first guide rail, the first rack is fixedly mounted on the upper end of the first mounting plate, the second mounting plate is fixedly mounted on the upper end of the second guide rail, and the second rack is fixedly mounted on the upper end of the second mounting plate.

[0009] As a further embodiment of the present invention, both the first rack and the second rack are arc-shaped, the first rack is located above the second rack, the adjusting gear is located in the middle of the first rack and the second rack and meshes with them, and the first rack and the second rack are concentrically arranged with the guide rail connecting shaft.

[0010] As a further embodiment of the present invention, a mounting bracket connecting block is fixedly installed on the upper end of the screw mounting bracket. The mounting bracket connecting block is embedded into the slots of the first guide rail rod and the second guide rail rod for fixed connection. The telescopic spline rod is inserted into the adjusting screw for telescopic movement. The universal joint is located below the guide rail connecting shaft, and the threads of the adjusting screws on both sides are opposite.

[0011] As a further embodiment of the present invention, the suction cup structure includes a suction cup mounting plate, a mounting plate connecting block, a suction cup connector, a vacuum suction cup, and an internal threaded sleeve. The suction cup mounting plate is disposed below the first guide rail and the second guide rail. The mounting plate connecting block is fixedly installed on the upper end of the suction cup mounting plate. The two suction cup connectors pass through the front and rear of the suction cup mounting plate. The vacuum suction cup is fixedly installed on the lower end of the suction cup connector, and the internal threaded sleeve is fixedly installed on the lower end of the suction cup mounting plate.

[0012] As a further embodiment of the present invention, the mounting plate connecting block is slidably connected to the slots of the first guide rail and the second guide rail, and the internal threaded sleeve is located in the middle of the two vacuum suction cups.

[0013] As a further embodiment of the present invention, the adjusting screw passes through the internal threaded sleeve and is threadedly connected thereto, and the suction cup mounting plate slides along the first guide rail and the second guide rail via the mounting plate connecting block.

[0014] As a further embodiment of the present invention, the rotary drive structure includes a drive motor, a drive pulley, a driven pulley, and a transmission belt. The drive motor is fixedly mounted above one end of the second guide rail rod, the drive pulley is fixedly mounted on the shaft end of the drive motor, the driven pulley is fixedly mounted on the end of the adjusting screw adjacent to the second guide rail rod, and the transmission belt is sleeved on the outside of the drive pulley and the driven pulley.

[0015] As a further embodiment of the present invention, the driving pulley and the driven pulley are of the same size, and the driving pulley and the driven pulley rotate synchronously through a transmission belt.

[0016] Compared with the prior art, the present invention has the following advantages: when adsorbing and connecting glass of different sizes, the operation of the drive motor can cause the adjusting screw to slide left and right, thereby increasing or decreasing the distance between the vacuum suction cups below the first guide rail and the second guide rail to accommodate the adsorption and connection of glass of different sizes. This enables quick adjustment of the position of all vacuum suction cups, and the structure is simple and more convenient for adjusting the adsorption size.

[0017] When adsorbing and connecting glass of different weights, the number of suction cup mounting plates and vacuum suction cups can be increased or decreased. Different numbers of vacuum suction cups can adsorb different weights to match glass of different weights for adsorption and connection, enabling quick adjustment of the adsorption and clamping weight and making it more convenient to handle glass of different weights.

[0018] When adsorbing and connecting flat glass at different angles, the operation of the regulating motor drives the first and second guide rails to rotate around the guide rail connection shaft, adjusting the angle between the first and second guide rails, and thus adjusting the angle of the vacuum suction cups below the first and second guide rails. This changes the angle of the vacuum suction cups on both sides, allowing for adsorption and connection of flat glass at different angles. This enables quick changes in the angle of the vacuum suction cups, making it easier to handle flat and curved glass at different angles.

[0019] When the gap between the vacuum suction cups needs to be adjusted after the first and second guide rails are bent, the two adjusting screws are rotated synchronously through the universal joint. This allows the gap between the two vacuum suction cups to be adjusted even after the two adjusting screws are bent. This enables the suction connection of glass with different angles and sizes, and allows for quick adjustment of the suction angle and position according to the change of glass, making it more suitable for handling different types of glass.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-7 As shown, a vacuum suction cup robot includes a central mounting plate 1, a robot connecting frame 2, first guide rails 5, and second guide rails 6. The robot connecting frame 2 is fixedly mounted on the upper end of the central mounting plate 1. The two first guide rails 5 and the two second guide rails 6 are located at the front and rear ends of the central mounting plate 1, respectively. Rotary shaft mounting plates 3 are welded to both the front and rear ends of the central mounting plate 1. Guide rail connecting shafts 4 are movably mounted on both the front and rear ends of the two rotating shaft mounting plates 3. The first guide rails 5 and the second guide rails 6 are fixedly connected to the outer sides of the guide rail connecting shafts 4. An angle adjustment mechanism is provided between the first guide rails 5 and the second guide rails 6. Section 7 has two screw mounting brackets 14 at the lower ends of the first guide rail 5 and the second guide rail 6. Adjusting screws 16 are movably mounted on the inner side of the screw mounting brackets 14, and there are two adjusting screws 16 located below the first guide rail 5 and the second guide rail 6. Telescopic spline rods 17 are movably mounted on the adjacent ends of the two adjusting screws 16. A universal joint 18 is fixedly mounted between the two telescopic spline rods 17. Multiple suction cup structures 19 are movably mounted on the lower ends of the first guide rail 5 and the second guide rail 6 in the middle of the two screw mounting brackets 14. A rotary drive structure 25 is fixedly mounted on one end of the second guide rail 6.

[0030] In this embodiment, the first guide rail rod 5 and the second guide rail rod 6 are the same size and are symmetrically arranged around the center of the guide rail connecting shaft 4. The first guide rail rod 5 and the second guide rail rod 6 rotate around the guide rail connecting shaft 4, and the guide rail connecting shaft 4 serves to movably install the first guide rail rod 5 and the second guide rail rod 6.

[0031] In this embodiment, the angle adjustment structure 7 includes an adjustment motor 8, an adjustment gear 9, a first mounting plate 10, a first rack 11, a second mounting plate 12, and a second rack 13. The adjustment motor 8 is fixedly mounted on the upper end of the central mounting plate 1, the adjustment gear 9 is fixedly mounted on the rotating shaft end of the adjustment motor 8, the first mounting plate 10 is fixedly mounted on the upper end of the first guide rail 5, the first rack 11 is fixedly mounted on the upper end of the first mounting plate 10, the second mounting plate 12 is fixedly mounted on the upper end of the second guide rail 6, and the second rack 13 is fixedly mounted on the upper end of the second mounting plate 12. The first mounting plate 10 and the second mounting plate 12 serve to mount the first rack 11 and the second rack 13.

[0032] In this embodiment, both the first rack 11 and the second rack 13 are arc-shaped. The first rack 11 is located above the second rack 13. The adjusting gear 9 is located between the first rack 11 and the second rack 13 and meshes with them. The first rack 11 and the second rack 13 are concentrically arranged with the guide rail connecting shaft 4. When the adjusting gear 9 rotates, it drives the first rack 11 and the second rack 13 to move in opposite directions. Then, the first rack 11 and the second rack 13 drive the first guide rail rod 5 and the second guide rail rod 6 to rotate around the guide rail connecting shaft 4.

[0033] In this embodiment, a mounting bracket connecting block 15 is fixedly installed on the upper end of the screw mounting bracket 14. The mounting bracket connecting block 15 is embedded into the slots of the first guide rail rod 5 and the second guide rail rod 6 for fixed connection. The telescopic spline rod 17 is inserted into the adjusting screw 16 for telescopic movement. The universal shaft 18 is located below the guide rail connecting shaft 4. The threads of the adjusting screws 16 on both sides are opposite. The opposite thread directions can drive the threaded sleeves 24 on both sides to move in opposite directions. When the adjusting screws 16 on both sides rotate, the telescopic spline rod 17 and the telescopic movement of the adjusting screw 16 cancel out the angle difference.

[0034] In this embodiment, the suction cup structure 19 includes a suction cup mounting plate 20, a mounting plate connecting block 21, a suction cup connector 22, a vacuum suction cup 23, and an internal threaded sleeve 24. The suction cup mounting plate 20 is disposed below the first guide rail rod 5 and the second guide rail rod 6. The mounting plate connecting block 21 is fixedly installed on the upper end of the suction cup mounting plate 20. The two suction cup connectors 22 pass through the front and rear of the suction cup mounting plate 20. The vacuum suction cup 23 is fixedly installed on the lower end of the suction cup connector 22. The internal threaded sleeve 24 is fixedly installed on the lower end of the suction cup mounting plate 20.

[0035] In this embodiment, the mounting plate connecting block 21 is slidably connected to the slots of the first guide rail rod 5 and the second guide rail rod 6, and the internal threaded sleeve 24 is located in the middle of the two vacuum suction cups 23. The mounting plate connecting block 21 achieves the effect of movably installing with the first guide rail rod 5 and the second guide rail rod 6.

[0036] In this embodiment, the adjusting screw 16 passes through the inner threaded sleeve 24 and is threadedly connected to it. The suction cup mounting plate 20 slides along the first guide rail 5 and the second guide rail 6 through the mounting plate connecting block 21. The adjusting screw 16 drives the inner threaded sleeve 24 to move left and right.

[0037] In this embodiment, the rotary drive structure 25 includes a drive motor 26, a drive pulley 27, a driven pulley 28, and a transmission belt 29. The drive motor 26 is fixedly mounted above one end of the second guide rail rod 6. The drive pulley 27 is fixedly mounted on the shaft end of the drive motor 26. The driven pulley 28 is fixedly mounted on the end of the adjusting screw 16 adjacent to the second guide rail rod 6. The transmission belt 29 is sleeved on the outside of the drive pulley 27 and the driven pulley 28. The drive pulley 27 and the driven pulley 28 are the same size. The drive pulley 27 and the driven pulley 28 rotate synchronously through the transmission belt 29. The operation of the drive motor 26 drives the adjusting screw 16 to rotate through the drive pulley 27, the driven pulley 28, and the transmission belt 29.

[0038] It should be noted that this invention is a vacuum suction cup robot. In use, the robot arm connecting frame 2 is used to connect the robot arm and move the robot arm as a whole. The suction cup connector 22 is used to connect the air pipe. When the robot arm moves above the glass, the vacuum suction cup 23 contacts the glass. After the air pipe is evacuated, the air between the vacuum suction cup 23 and the glass is extracted from the suction cup connector 22, so that a vacuum negative pressure state is formed between the vacuum suction cup 23 and the glass, thereby making the vacuum suction cup 23 firmly connected to the glass and realizing the adsorption and clamping of the glass. Therefore, when the robot arm moves, the glass can be moved. After the glass is moved to the designated position, the air pipe is vented, and the vacuum suction cup 23 and the glass are restored to normal pressure to release the glass and complete the glass handling and movement.

[0039] When adsorbing and connecting glass of different sizes, the drive motor 26 drives the drive pulley 27 to rotate. The drive pulley 27 drives the driven pulley 28 and the adjusting screw 16 to rotate through the transmission belt 29. The adjusting screw 16 rotates around the inner side of the screw mounting bracket 14. When a single adjusting screw 16 rotates, it also drives the other adjusting screw 16 to rotate through the telescopic spline rod 17 and the universal joint 18. Then, through the threaded connection between the adjusting screw 16 and the inner threaded sleeve 24, the inner threaded sleeve 24 is driven to move left and right. This causes the suction cup mounting plate 20 to slide around the first guide rail 5 and the second guide rail 6 through the mounting plate connecting block 21. The threads of the two adjusting screws 16 are opposite, causing the suction cup mounting plate 20 below the first guide rail 5 and the second guide rail 6 to move in opposite directions. Therefore, the distance between the vacuum suction cup 23 below the first guide rail 5 and the second guide rail 6 is increased or decreased to accommodate the adsorption and connection of glass of different sizes.

[0040] When adsorbing and connecting glass of different weights, the mounting plate connecting block 21 is connected to the slot at the bottom of the first guide rail rod 5 and the second guide rail rod 6 by snap-fitting. Therefore, by quickly disassembling and assembling the mounting plate connecting block 21, the number of suction cup mounting plates 20 and vacuum suction cups 23 can be increased or decreased. Different numbers of vacuum suction cups 23 adsorb different weights to match glass of different weights for adsorption and connection.

[0041] When adsorbing and connecting flat glass at different angles, the operation of the adjusting motor 8 drives the adjusting gear 9 to rotate. The rotation of the adjusting gear 9 is driven by the meshing connection between the first rack 11 and the second rack 13. Then, the first rack 11 and the second rack 13 drive the first guide rail rod 5 and the second guide rail rod 6 to rotate around the guide rail connecting shaft 4, adjusting the angle between the first guide rail rod 5 and the second guide rail rod 6. This, in turn, adjusts the angle of the vacuum suction cup 23 below the first guide rail rod 5 and the second guide rail rod 6, causing the angle of the vacuum suction cup 23 on both sides to change, so as to cooperate with the adsorption and connection of flat glass at different angles.

[0042] When the gap between the first guide rod 5 and the second guide rod 6 needs to be adjusted after bending, the bending of the first guide rod 5 and the second guide rod 6 simultaneously drives the lower adjusting screw 16 to bend, and the universal joint 18 between the two adjusting screws 16 rotates. The angle difference generated between the two adjusting screws 16 is offset by the telescopic spline rod 17 extending and retracting within the adjusting screw 16. Then, when the two adjusting screws 16 rotate, they still maintain synchronous rotation transmission through the universal joint 18, so that after the two adjusting screws 16 bend, the distance between the two vacuum suction cups 23 can still be adjusted, which can be used to adsorb and connect glass with different angle planes and different sizes.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
