Description

Technical Field

[0001] This application relates to the manufacture of graphite materials, and more particularly to a graphite sheet flip-over spraying device. Background Technology

[0002] Graphite sheets are a new type of thermally conductive and heat-dissipating material with a unique grain orientation. In the production and processing of graphite sheets, in order to improve their heat dissipation effect and service life, anti-corrosion coatings are usually sprayed onto the surface of the graphite sheets for protection.

[0003] Currently, graphite sheets require manual flipping during processing. When workers handle the graphite sheets, their fingers inevitably touch the spraying surface, which leads to a decrease in the quality of the graphite sheets. Furthermore, manual placement can cause deviations in the original position of the graphite sheets, resulting in inaccurate spraying positions. Therefore, the quality of graphite sheet spraying is reduced.

[0004] Regarding the relevant technologies mentioned above.

[0005] 1. Technical problems to be solved The purpose of this application is to provide a coating device with a flip-up graphite sheet, which solves the problems of manual handling of graphite sheets causing fingers to touch the surface of the graphite sheets and deviations in the position of the graphite sheets when placing them after handling, thus affecting the coating quality of the graphite sheet processing.

[0006] The graphite sheet flip-over spraying equipment provided in this application adopts the following technical solution: it includes a mounting frame structure, a conveying structure, an ABB robotic arm, a flipping structure, a moving structure, a first drying structure, a placement plate, and a second drying structure. The two mounting frame structures are fixedly connected to a conveying structure. A placement plate is fixedly connected to one side of the conveying structure. An ABB robotic arm is fixedly connected to the upper end of the placement plate. The placement plate is fixed between the two mounting frame structures. The output end of the ABB robotic arm is rotatably connected to the flipping structure. Two moving structures are fixedly connected to the bottom of each of the two mounting frame structures. The flipping structure includes a fixed block, a third motor, a gripper frame, a first motor, a bidirectional lead screw, a gripper plate, a bearing seat, a second motor, and a flipping disk. The mounting frame structure includes two frames. The conveying structure includes a conveyor. The moving structure includes multiple cylindrical rods. The first drying structure includes two assembly shells. By adopting the above technical solution, through the configuration of the gripper frame, the second motor, the bidirectional lead screw, and the gripper plates, during use, after the coating is completed, the ABB robotic arm is activated to adjust the position of the gripper frame, and then the second motor is activated to make the bidirectional lead screw engage the gripper plates, thereby driving the two gripper plates to move to their positions and clamp the graphite sheet. Compared with manual handling of graphite sheets and manual flipping, which can cause human fingers to touch the graphite sheet and affect the surface quality of the coated graphite sheet, this device uses the gripper plates to come together and then hold the two sides of the graphite sheet, thus avoiding the overall quality degradation of the graphite sheet after coating. Compared with manual handling, the mechanical program setting allows for mechanical placement after mechanical clamping, and the placement position will not be deviated. At the same time, the opening and closing of the mechanical gripper can adapt to various specifications of graphite sheets, making it more widely applicable.

[0007] Preferably, a third motor is fixedly connected to one side of the fixing block, the fixing block is fixedly connected to the output shaft of the ABB robotic arm, the output end of the third motor is fixedly connected to a gripper frame via a coupling, a first motor is fixedly connected to the outside of the gripper frame, the output end of the first motor is fixedly connected to a bidirectional lead screw via a coupling, a bearing seat rotating disk is sleeved at the end of the bidirectional lead screw rotating disk away from the first motor rotating disk, the bearing seat rotating disk is fixedly connected to the gripper frame rotating disk, the bidirectional lead screw rotating disk penetrates into the interior of the gripper frame rotating disk, two gripper plate rotating disks are threadedly sleeved on the outer wall of the bidirectional lead screw rotating disk, and both gripper plate rotating disks are slidably connected to the interior of the two gripper frame rotating disks via T-shaped connecting sliders.

[0008] Preferably, a second motor rotating disk is fixedly connected to one of the gripper rotating disks on the side away from the first motor rotating disk, and a tilting disk is connected to one side of one of the gripper rotating disks. The output end of the second motor rotating disk is fixedly connected to a rotating disk via a coupling. The rotating disk extends through to one side of the gripper rotating disk away from the first motor rotating disk. By adopting the above technical solution, the ABB robotic arm is started, with the power supply providing power. The ABB robotic arm drives the extension arm to twist, and the extension arm drives the twisting head to rotate. Then, the twisting head rotates in conjunction with the connecting table, and finally the connecting table drives the mounting rod to adjust the position of the gripper frame.

[0009] Preferably, a storage tank is fixedly connected to one side of each of the two frames, a pump body is fixedly connected to the top of each of the two storage tanks, a pumping pipe is connected to the inlet of each of the two pumping pumps, the pumping pipe is connected to the two storage tanks, a discharge pipe is connected to the outlet of each of the two pumping pumps, an aggregating box is fixedly connected to the upper end of each of the two frames, the aggregating box is connected to the two discharge pipes, and two nozzles are connected to the bottom of each of the two aggregating boxes. Each set of nozzles is on the same straight line, and the two frames are placed on both sides of the ABB robotic arm.

[0010] By adopting the above technical solution, two pump bodies are turned on, and the pump bodies draw the spraying liquid from the two storage tanks through the pumping pipes, and then draw it to the collection tank through the discharge pipes, so that the nozzles spray the graphite sheets passing below.

[0011] Preferably, the conveyor is fitted with a conveyor belt, and the outer wall of the conveyor belt is fixedly connected with a plurality of positioning slots. The plurality of positioning slots are arranged in a through-line and correspond to a plurality of nozzles. The outer side of the plurality of positioning slots has a plurality of through rectangular slots. The middle of each of the plurality of positioning slots is fixedly connected with a plurality of horizontal columns. The positioning slots are made of rubber.

[0012] By adopting the above technical solution, the conveyor is turned on and put into operation, so that the positioning slot shell is transported to complete the subsequent processing.

[0013] Preferably, each of the cylindrical rods is rotatably connected to the mounting frame structure, and each of the cylindrical rods is fixedly connected to a hub at its bottom end. Each of the hubs is rotatably connected to a roller via a connecting wheel rod. Each of the hubs has a bolt rod threaded onto one side. Each of the bolt rods has a foot pedal fixedly connected to the end away from the hub. Each of the bolt rods has a baffle fixedly connected to its outer wall, and the baffles can be in contact with the rollers.

[0014] By adopting the above technical solution, when the foot pedal is stepped on, the bolt rod on one side of the baffle rotates when the baffle is twisted, thereby engaging with the thread groove of the wheel rod of the roller. At this time, the baffle on the outer wall of the bolt rod is pressed against the roller, thereby increasing the friction.

[0015] Preferably, a first drying structure and a second drying structure are fixedly connected to the upper ends of the two sides of the upper end of the conveying structure, respectively. The internal structures of the first drying structure and the second drying structure are identical. The first drying structure and the second drying structure are respectively placed on both sides of the ABB robotic arm. Dryers are fixedly connected to the upper ends of the two assembly shells.

[0016] By adopting the above technical solution, the graphite sheet can be dried after being sprayed on one side and then flipped by the ABB robotic arm. When the exhaust fan is running, the high-temperature hot air generated during drying is directed upward through the baffle plate to prevent the hot air from spraying onto the worker's arm and causing damage to the worker's skin.

[0017] Preferably, the baking output ends of the two dryers are placed inside the assembly shell, an exhaust fan is fixedly connected to one side of the two assembly shells, and a wind baffle is fixedly connected to one side of the two assembly shells, with the two wind baffles placed on one side of the exhaust fan.

[0018] By adopting the above technical solution, as the conveyor continues to run, the flipped graphite sheet is transported to another frame, where the other side is sprayed and dried by the nozzle.

[0019] 2. Technical problems to be solved: This graphite sheet flipping spraying equipment, through the configuration of a gripper frame, a second motor, a bidirectional lead screw, and gripper plates, allows the ABB robotic arm to adjust the position of the gripper frame after spraying. Then, the second motor is activated, causing the bidirectional lead screw to engage the gripper plates, thereby moving the two gripper plates to their designated positions and clamping the graphite sheet. Compared to manual handling and flipping of graphite sheets, which can lead to fingers touching the sheet and affecting the surface quality after spraying, this fully automated mechanical gripping effectively prevents the gripper plates from contacting the surface of the sprayed graphite sheet. This avoids a decline in the overall quality of the sprayed graphite sheet. Furthermore, the mechanical program ensures precise placement after mechanical gripping, and the opening and closing of the mechanical grippers can accommodate graphite sheets of various sizes, making it more widely applicable.

[0020] This type of graphite sheet flip-up spraying equipment, through the arrangement of a positioning tank, a first drying structure, a second drying structure, and a nozzle, allows the graphite sheet to be initially positioned by the operator when placed on the positioning tank, ensuring that the graphite sheet always corresponds to the nozzle position and guaranteeing spraying quality. Furthermore, when transporting the graphite sheet on the positioning tank, compared to directly placing the graphite sheet on a conveyor belt, this device uses the positioning tank to support the thin graphite sheet. The height between the graphite sheet and the conveyor belt is increased, making it easier to clamp the graphite sheet. Compared to drying the graphite sheet all at once after spraying, this device uses a second drying structure to dry one side of the graphite sheet. This causes the undried sprayed surface to come into contact with the sheet. After flipping the sheet, the other side is sprayed, ensuring that the surface of the sprayed graphite sheet will not stick to the positioning groove after flipping. This effectively prevents the undried graphite sheet from being rubbed and ensures a good overall quality of graphite sheet spraying. Attached Figure Description

Two gripper plates 407 are threaded onto the outer wall of the bidirectional lead screw 406. Both gripper plates 407 are slidably connected to the inside of the two gripper frames 404 via a T-shaped connector slider.

Compared to manual handling and flipping of graphite sheets, which can lead to fingers touching the sheet and affecting the surface quality after coating, this fully automated mechanical clamping effectively prevents the gripper plates 407 from contacting the coated graphite sheet surface. This avoids a decline in the overall quality of the coated graphite sheet. Furthermore, the mechanical program ensures precise placement after mechanical clamping, and the opening and closing of the mechanical grippers can accommodate graphite sheets of various sizes, making it more widely applicable.

[0025] Example 2: A rotatable graphite sheet spraying device, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8The system includes a conveyor belt 202 fitted around the conveyor 201. Multiple positioning slots 203 are fixedly connected to the outer wall of the conveyor belt 202. These positioning slots 203 are arranged linearly and correspond to multiple nozzles 107. Multiple through rectangular slots 205 are formed on the exterior of each positioning slot 203. Multiple horizontal columns 204 are fixedly connected to the center of each positioning slot 203.

A baffle 506 is fixedly connected to the outer wall of each bolt rod 504, allowing the baffle 506 to contact the roller 503. A first drying structure 7 and a second drying structure 9 are fixedly connected to the upper ends of both sides of the upper end of the conveying structure 2. The internal structures of the first drying structure 7 and the second drying structure 9 are identical. The first drying structure 7 and the second drying structure 9 are respectively positioned on both sides of the ABB robotic arm 3. A dryer 702 is fixedly connected to the upper end of each of the two assembly shells 701. The two dryers 702... The baking output end is located inside the assembly shell 701. An exhaust fan 703 is fixedly connected to one side of each of the two assembly shells 701, and two wind deflectors 704 are fixedly connected to one side of each of the two assembly shells 701. The two wind deflectors 704 are positioned to the side of the exhaust fan 703. Through the positioning slot shell 203, the first drying structure 7, the second drying structure 9, and the spray nozzle 107, after the graphite sheet is placed above the positioning slot shell 203, the operator can initially position the graphite sheet, ensuring that the graphite sheet always corresponds to the position of the spray nozzle 107, thus ensuring the spraying quality. Simultaneously, the graphite sheet is placed on the positioning slot shell 203 for… During transport, compared to directly placing the graphite sheet onto the conveyor belt, this device uses the positioning groove 203 to lift the graphite sheet, thus increasing the height between the graphite sheet and the conveyor belt. This makes it easier to clamp the graphite sheet. Instead of drying the coated graphite sheet all at once, this device uses the second drying structure 9 to dry one side of the graphite sheet. This prevents the undried coated side from being touched. After flipping the sheet, the device sprays the other side, ensuring that the coated graphite sheet surface does not stick to the positioning groove 203 after flipping. This effectively prevents the undried graphite sheet from being touched and ensures a good overall quality of the graphite sheet coating.

[0026] The implementation principle of this application embodiment is as follows: First, when needed, the worker steps on the foot pedal 505, causing the baffle 506 to twist. This rotates the bolt rod 504 on one side of the baffle 506, engaging with the threaded groove of the wheel rod of the roller 503. At this time, the baffle 506 on the outer wall of the bolt rod 504 presses tightly against the roller 503, increasing friction and preventing the roller 503 from moving. The cylindrical rod 501 facilitates steering when the device is moved. Subsequently, the staff turned on the conveyor 201, putting it into operation. Simultaneously, the staff placed the graphite sheets to be coated onto the horizontal columns 204 at the top of the multiple positioning slots 203. This allowed the positioning slots 203 to initially position the placed workpieces and provided space for subsequent clamping and flipping of the graphite sheets. The horizontal columns 204 and rectangular slots 205 allowed hot air to envelop the entire graphite sheet through the gaps during the subsequent drying process, thereby improving the drying efficiency. As the conveyor 201 moved, the conveyor belt 202 moved the multiple positioning slots 203. Then, the operator turns on the two pump bodies 103, which draw the spraying liquid from the two storage tanks 102 through the pumping pipes 104, and then pump it through the discharge pipes 105 to the collection tank 106, so that the spray nozzles 107 can spray the graphite sheets passing below. Next, the staff activated the dryers 702 and exhaust fans 703 on the top and side of the two assembly shells 701. The dryers 702 dried the graphite sheets passing below. Because the two dryers 702 are located on either side of the ABB robotic arm 3, the graphite sheets can be dried after being coated on one side before being flipped by the ABB robotic arm 3. The exhaust fan 703, while running, directs the high-temperature air generated during drying upwards through the baffle 704, preventing the hot air from hitting the staff's arms and causing skin damage. After the spraying is completed, the ABB robotic arm 3 is activated. Once in working mode, multiple axes of the ABB robotic arm 3 rotate, causing the third motor 403 to change position. Simultaneously, the gripper frame 404 moves to the position of the positioning slot 203. When the gripper frame 404 is above the positioning slot 203, the first motor 405 is activated, driving the bidirectional lead screw 406 to rotate. The bidirectional lead screw 406 then engages with the threaded outer wall of the gripper piece 407, thereby moving the gripper piece 407. The graphite sheet on the horizontal column 204 is then clamped. The second motor 409 is then started to drive the rotating disk 411 to rotate. At the same time, the flipping disk 410 also rotates, thereby flipping the clamped graphite. The position is then adjusted again by the ABB robotic arm 3, and the flipped graphite sheet is placed back above the positioning slot 203. As the conveyor 201 continues to run, the flipped graphite sheet is transported to another frame 101, where the spray nozzle 107 completes the spraying and drying of the other side. The dried graphite sheet is then removed by the staff.
