Description

Technical Field

[0001] This utility model relates to the field of graphene technology, specifically to a graphene tube resistance control device. Background Technology

[0002] Graphene, due to its high conductivity, thermal stability, and mechanical strength, is an ideal material for resistance control. Furthermore, the conductivity of graphene is tunable; by changing factors such as the number of graphene layers and the degree of doping, precise control of the resistance value can be achieved. This characteristic makes graphene a promising material for a wide range of applications in the field of resistance control.

[0003] Existing graphene tube resistance control equipment has a relatively low degree of automation, and the loading and unloading are mostly done manually. The work efficiency is easily affected by manual operation, resulting in low overall work efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, the graphene tube resistance control device provided by this utility model includes a workbench and a graphene tube. A rotatable workstation disk is provided on one side above the workbench. Three sets of product fixing fixtures are provided on the workstation disk. A placement area is provided above the workbench. A gantry module for conveying untested graphene tubes in the placement area to the workstation disk is installed above the workbench.

[0006] The workbench is also equipped with a resistance control mechanism, which is located above the workstation disc. The resistance control mechanism includes a crossbeam frame and resistance testing components and laser resistance control components installed on both sides below the crossbeam frame.

[0007] The gantry module sends the untested graphene tube to station one on the station disk. The station disk rotates to move the graphene tube to station two. After the resistance testing component tests the resistance, the station disk rotates to move the graphene tube to station three. The laser resistance control component removes the graphite from the product to adjust the resistance of the graphene tube.

[0008] The laser-controlled resistivity assembly includes a laser located above station three, which removes graphite from the graphene tube using laser light.

[0009] Furthermore, the placement area includes product fixture A, product NG fixture and product fixture B located above the workbench. Untested graphene tubes are placed on product fixture A and product fixture B. The product NG fixture is placed between product fixture A and product fixture B and is used to place defective graphene tubes.

[0010] Furthermore, the gantry module is equipped with a first Z-axis conveying module and a second Z-axis conveying module. Both the first Z-axis conveying module and the second Z-axis conveying module are equipped with robotic arms for gripping graphene tubes. The robotic arms are used to deliver the graphene tubes to a designated position.

[0011] Furthermore, three fixed plates are fixedly installed on the outer periphery of the workstation disc, and a positioning seat is slidably installed on the top of each fixed plate. A fixing fixture for positioning the graphene tube is installed on the positioning seat, and a movable plate connected to the positioning seat is slidably installed at the bottom of the positioning seat. Three lifting cylinders are set above the worktable, and the three lifting cylinders are respectively set below workstation one, workstation two and workstation three. When the lifting cylinders are pushed out, they can lift the movable plate to make the positioning seat slide upward.

[0012] Furthermore, a CCD inspection camera is also installed on the crossbeam frame, and the CCD inspection camera is located above the second workstation.

[0013] Furthermore, the laser rheostat control assembly also includes a height adjustment mechanism for adjusting the height of the laser.

The resistance testing component includes resistance testing ends disposed on both sides of the end.

[0015] Furthermore, it also includes the housing and the opening and closing doors installed on the housing.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: Product fixtures A and B are manually loaded. A robotic arm on the first or second Z-axis conveying module picks up a graphene tube from product fixture A and places it onto the product fixing fixture at station one on the workstation disk. The fixture fixes the graphene tube and moves it to station two. The product fixing fixture rises, and the coaxial rotation mechanism clamps the graphene tube and rotates the CCD detection camera to find the graphene tube's poles to a horizontal position. The resistance testing component then tests the resistance and sends the test value to the industrial computer to determine subsequent excitation. The optical motion test completes, the fixed fixture rises to hold the graphene tube, the coaxial rotation mechanism opens, the product fixed fixture lowers, and the rotating disk at the workstation moves the graphene tube to workstation three. The laser, based on the test data from workstation two, determines whether to remove graphite from the graphene tube and how much graphite to remove. After completion, the resistance is retested using the resistance testing component above workstation three. If it fails, the graphite is removed again by laser; if it passes, it moves to workstation one. A robotic arm first removes the completed graphene tube from the product fixed fixture, and then another robotic arm loads a new graphene tube. The robotic arm, based on the NG / OK result, loads the NG tube onto the product NG fixture and the OK tube onto product fixture A. After the graphene tube on product fixture A is completed, it directly transfers to product fixture B. At this point, a manual removal of product fixture A is performed, and a new fixture and graphene tube are then loaded. Attached Figure Description

Furthermore, the first Z-axis conveying module 16 and the second Z-axis conveying module 17 can load and unload in one operation, reducing the number of handling operations and improving equipment efficiency.

[0027] Three fixed plates 12 are fixedly installed on the outer periphery of the workstation disc 18. A positioning seat 13 is slidably installed on the top of each fixed plate 12. A fixing fixture 14 for positioning the graphene tube 15 is installed on the positioning seat 13. A movable plate 11 connected to the positioning seat 13 is slidably installed on the bottom of the positioning seat 13. Three lifting cylinders 10 are arranged above the worktable, respectively below workstations one, two, and three. When the lifting cylinders 10 extend, they can lift the movable plate 11, thus positioning the graphene tube 15. 3. Slide upwards, and the robot on the first Z-axis conveying module 16 or the second Z-axis conveying module 17 picks up a graphene tube 15 from the product fixture A6 and places it on the product fixing fixture at station one on the station disk 18. The fixture fixes the graphene tube 15 and moves to station two. The lifting cylinder 10 works to raise the product fixing fixture. At this time, the coaxial rotation mechanism can clamp the graphene tube 15. When the graphene tube 15 is unloaded from the station disk 18, the lifting cylinder 10 can restore the product fixing fixture to its original height so that it can be picked up and sent away by the robot.

[0028] The workbench is also equipped with a resistance control mechanism, which is located above the workstation disk 18. The resistance control mechanism includes a crossbeam frame and resistance testing components and laser resistance control components installed on both sides below the crossbeam frame.

[0029] The laser resistivity control assembly includes a laser 3, which is located above the third station. The laser 3 removes graphite from the graphene tube 15 using laser light.

[0031] The gantry module 5 sends the untested graphene tube 15 to station one on the station disk 18. The station disk 18 rotates to move the graphene tube 15 to station two.

[0032] Working principle: Product jigs A6 and B8 are manually loaded. A robotic arm on either the first Z-axis conveyor module 16 or the second Z-axis conveyor module 17 picks up a graphene tube 15 from jig A6 and places it onto the product fixing jig at station one on the workstation disk 18. The jig fixes the graphene tube 15 and moves to station two. The product fixing jig rises, and the coaxial rotation mechanism clamps the graphene tube 15, then rotates the CCD detection camera 9 to locate the pole of the graphene tube 15 and bring it to a horizontal position. The resistance testing component then tests the resistance and sends the test value to the industrial computer to determine subsequent laser actions. After the graphene tube 15 is lifted and secured by the fixed fixture, the coaxial rotation mechanism opens, the product fixing fixture lowers, and the workstation disk 18 rotates the graphene tube 15 to workstation three. Laser 3 determines whether to remove the graphite from the graphene tube 15 based on the test data from workstation two, and how much graphite to remove. After completion, the resistance is retested using the resistance testing component above workstation three. If it fails, the graphite is removed again by laser; if it passes, it moves to workstation one. A robotic arm first removes the completed graphene tube 15 from the product fixing fixture, and then another robotic arm loads a new graphene tube 15. The robotic arm, based on the NG / OK result, loads the NG product onto product fixture 7 if NG, and onto product fixture A6 if OK. After the graphene tube 15 on product fixture A6 is completed, it directly transfers to product fixture B8 to retrieve the graphene tube 15. At this point, a manual removal of product fixture A6 is performed, and a new fixture and graphene tube 15 are then loaded.
