Description

Technical Field

[0001] The present application belongs to the field of laser etching technology, and in particular relates to an integrated machine for storing, transporting and marking identification plates. Background Art

[0002] The identification plates used in power grid facilities usually contain important information such as the name, number, location, maintenance cycle, and management unit of the power equipment.

[0003] With the continuous expansion of the scale of power grid equipment and the improvement of the requirements for power facility management, there are situations where signboards are urgently needed but have not been marked. For example, during the inspection process, the inspection personnel find that the signboards need to be replaced, and they can only record them and return to the unit for operation and marking. If the signboard transfer and marking can be remotely controlled on-site, not only can the signboard information be directly input according to the on-site situation, but the urgently needed signboards can also be obtained as soon as possible after returning to the unit.

[0004] With the advancement of automation technology, more and more industrial fields have begun to introduce automation equipment to replace manual operations. The management of power grid facilities has also begun to gradually introduce these technologies in order to improve the efficiency and accuracy of identification work.

[0005] Different colored signboards are used in different power equipment or environments. At present, the marking of signboards is usually completed by manual handling and marking on site, that is, the inspection personnel place a single signboard on the marking area of ​​the laser engraving machine, enter the information on the local computer and complete the marking. The color and transportation of the signboard are completed manually.

[0006] In addition, automated sign transfer usually involves grabbing the sign from top to bottom through a grabbing structure. The sign is a thin plate structure. If the grabbing force is too small, the sign is likely to fall off. If the grabbing force is too large, the sign is likely to deform. If the sign is laid flat, it takes up a large amount of space. If the sign is stacked, it is easy for the sign to stick together due to heavy pressure, friction, static electricity, and environmental influences.

[0007] Therefore, developing an all-in-one machine for storing, transporting and marking signboards that integrates automation and intelligence can not only improve work efficiency and reduce manpower consumption, but also ensure that the signboards can be used at any time, and effectively reduce the risk of signboard deformation, ensuring that the management of power facilities is more scientific and accurate.

[0061] The transfer assembly 3 of the present embodiment includes a movable arm, on which a grabbing assembly is installed, in which a lifting component capable of lifting and lowering motion is arranged, and on which a grabbing component is installed. As a specific structure, the movable arm of the present embodiment is a three-section structure, in which a bottom support tube 10 is installed on the base 1, and a first drive motor 11 is installed on the upper end of the bottom support tube 10, and a connecting arm is installed on the output shaft of the first drive motor 11, and a second drive motor 12 is installed at one end of the connecting arm away from the first drive motor 11, and the output shaft of the second drive motor 12 is fixedly connected to the connecting arm, and a main body of the second drive motor 12 is fixed on a first shell 17, in which a lifting component is installed, and a second shell 18 is arranged on the periphery of the lifting component.

[0062] Specifically, a fixed bracket 13 is installed in the first shell 17, and a lifting component is fixed on the fixed bracket 13. The lifting component includes a guide rail 16, a moving block 22 moving on the guide rail 16 is installed on the guide rail 16, a lifting rod 15 is installed on the moving block 22, and a grabbing component is installed at the lower end of the lifting rod 15.

[0063] More specifically, as a detailed structure, in this embodiment, the power component of the lifting assembly is the third drive motor 14, and a screw 21 is also installed on the guide rail 16. The moving block 22 is connected to the screw 21. The third drive motor 14 drives the screw 21 to rotate and then drives the moving block 22 to move along the guide rail 16. As another solution, two synchronous pulleys are installed on the guide rail 16, and a synchronous belt is installed on the two synchronous pulleys. The moving block 22 is installed on the synchronous belt, and the third drive motor 14 drives the synchronous pulley to rotate and then drives the moving block 22 to move along the guide rail 16.

[0064] Since the identification plate 41 has a planar structure, the core structure of the grabbing component of this embodiment is the suction cup 19. Specifically, the grabbing component includes a fixed cylinder, the suction cup 19 is installed at the lower end of the fixed cylinder, and an air pump 20 is installed in the fixed cylinder. The air pump 20 is connected to the cavity in the suction cup 19 through a hollow pipe structure.

[0065] The tray assembly 2 of this embodiment includes a support rod 34 installed on the base 1, and the upper end of the support rod 34 protrudes from the base 1. Specifically, the support rod 34 in the base 1 is equipped with multiple groups of bearings 35, and the outer periphery of the bearing 35 is equipped with a rotating wheel, which is connected to driving wheels at different positions through a rack, a chain or a belt. Correspondingly, the rotating wheel and the driving wheel are respectively a type of gear, a sprocket, and a pulley, and the rotating wheels at corresponding positions are driven to rotate by motors arranged at different positions. Similarly, each group of bearings 35 corresponds to a sleeve, and the sleeve extends out of the base 1. A tray 36 is installed on each sleeve. Specifically, taking five trays 36 as an example, five sleeves of different lengths are installed on the support rod 34, and the innermost sleeve is equipped with a bearing 35, and a bearing 35 is installed between the sleeves. A rotating wheel is installed on each sleeve, and the rotating wheels are arranged along the height direction of the support rod 34.

[0066] Each tray 36 of the present embodiment can hold identification plates 41 of the same color. Therefore, five trays 36 can hold identification plates 41 of five different colors, so that different contents can be printed on identification plates 41 of different colors. Before marking identification plates 41 of different colors, the tray 36 at the corresponding position can be rotated out by controlling the intelligent terminal 8 or the local computer 5.

[0067] Example 2

[0068] This embodiment is based on the structure of the first embodiment.

[0069] As a specific structure of the tray 36 , in addition to being stacked together, the identification plates 41 in this embodiment can also be separated and arranged in the tray 36 . The advantage of arranging the identification plates 41 separately is that it can avoid the adhesion of adjacent identification plates 41 .

[0070] Specifically, a support seat 37 is installed in the tray 36 of this embodiment, and the support seat 37 includes a connecting plate 38. The connecting plate 38 has a plurality of fixed plates 39 arranged at intervals. A movable plate 40 is hingedly installed on the fixed plate 39. The movable plate 40 can rotate upward. The lower end of the fixed plate 39 has a protrusion, which is used to support the movable plate 40 and limit the movable plate 40 from rotating downward. The angle at which the movable plate 40 can rotate is designed so that the identification plate 41 can pass through the tray 36, so that the identification plate 41 can smoothly pass through the movable plate 40 above.

[0071] As one embodiment, the connecting plate 38 is L-shaped, and the fixing plate 39 is connected to both plates on the connecting plate 38. As another embodiment, the connecting plate 38 is flat, and the fixing plate 39 is fixedly connected to the connecting plate 38. The connecting plate 38 is fixed in the tray 36 by bolts or screws.

[0072] This embodiment discloses the detailed structure of the grabbing component. Specifically, the fixed cylinder of the grabbing component includes an upper fixed cylinder 27, a lower fixed cylinder 29 and a side fixed cylinder 28. The side fixed cylinder 28 is arranged on one side of the upper fixed cylinder 27, and the lower fixed cylinder 29 is arranged at the lower end of the upper fixed cylinder 27. As a connection scheme, the lower fixed cylinder 29 is connected to the upper fixed cylinder 27 through threads.

[0073] A pressure sensor 32 is installed in the upper fixed cylinder 27, and the pressure sensor 32 is screwed together with the upper fixed cylinder 27, and the probe of the pressure sensor 32 is arranged downward. A through groove is opened on the upper fixed cylinder 27, and the through groove is used for the wire of the pressure sensor 32 to pass through the upper fixed cylinder 27. The side fixed cylinder 28 is used to install the air pump 20. An end cover is installed on the upper end of the side fixed cylinder 28. The upper fixed cylinder 27 is connected to the lifting rod 15 through threads.

[0074] The present application uses at least two suction cups 19 to avoid the problem of instability of a single suction cup 19 grabbing the identification plate 41. For example, the present embodiment uses four suction cups 19, and the four suction cups 19 are connected together by a connecting rod 30. The connecting rod 30 has a protrusion 31 at the gathering point. The protrusion 31 is arranged in the lower fixed tube 29 and is aligned with the probe of the pressure sensor 32. Specifically, a through groove is opened on the lower fixed seat, and the connecting rod 30 is inserted into the through groove, so that the protrusion 31 can move a certain distance in the lower fixed tube 29.

[0075] The hollow tube is arranged inside the connecting rod 30, or the connecting rod 30 is opened to form a hollow tube structure. The air pump 20 is connected to the hollow tube on the connecting rod 30 through the air delivery pipe 33, and is connected to the cavity in the suction cup 19 through the hollow tube. In addition, in this embodiment, an air storage chamber 42 is arranged in the lower fixed cylinder 29, and the air storage chamber 42 is connected to the hollow tube on the connecting rod 30 through a connecting pipe. The function of the air storage chamber 42 is to ensure that the protrusion 31 stably contacts the probe to prevent the protrusion 31 from falling back after contacting the probe. In order to solve the problem of inaccurate detection caused by this, as an implementation scheme, the air storage chamber 42 is two contacting sleeves, referred to herein as an upper sleeve and a lower sleeve. The sleeves are rigid structural parts. A seal is arranged between the two contacting sleeves to avoid air leakage, and the upper sleeve can move along the lower sleeve. A sealing ring or other structure can be added between the two. The air pump 20 is connected to the hollow tube of the connecting rod 30 through an air supply pipe 33. The air pump 20 and the compressed suction cup 19 control the amount of gas in the hollow tube and the air storage chamber 42.

[0076] In addition, based on this, in order to avoid the situation that the lifting rod 15 stops suddenly but still has inertia and has a tendency to move downward, resulting in the air storage chamber being compressed and causing the gas in the air storage chamber to rebound, thereby causing the problem of excessive floating detected by the pressure sensor, the present embodiment is equipped with a damping member 26 on the lifting assembly. Specifically, a damping wheel 43 is installed in the damping member 26, and the damping wheel 43 is in contact with the surface of the lifting rod 15, so that the lifting rod 15 drives the damping wheel 43 to rotate during the process of rising or falling, so as to avoid the instability of the lifting rod 15 when the third drive motor 14 is started or stopped suddenly. As a specific solution, the outer periphery of the damping wheel 43 is an arc-shaped area concave inwardly, and the arc-shaped area is in contact with the lifting rod 15. As another specific solution, the outer periphery of the damping wheel 43 has a pattern, and the pattern is pressed on the lifting rod 15. The shaft of the damping wheel 43 is fixed to the shell of the damping member 26 through a contact seat 44, and the rotation of the damping wheel 43 is damped by friction. For example, the contact seat 44 is a nylon seat body or a rubber seat body.

[0077] In this embodiment, a fixing plate 23 is installed on the moving block 22, and the fixing plate 23 is L-shaped. A part of the fixing plate 23 is connected to the moving block 22, and the other part of the fixing plate 23 has a through hole, through which the lifting rod 15 passes. A cylinder 24 is installed at the head end of the lifting rod 15, and the cylinder 24 and the lifting rod 15 are clearance-fitted, that is, the lifting rod 15 can move inside the cylinder 24, and a buffer block is installed at the top end of the lifting rod 15, and the buffer block is fixedly connected to the lifting rod 15, and a spring 25 is arranged between the lower end of the cylinder 24 and the fixing plate 23. Therefore, the lifting rod 15 is restricted by the spring 25 and the buffer block, so that when the lifting rod 15 touches the bottom or temporarily moves, the lifting rod 15 can move slightly within the compressible range of the spring 25.

[0078] In the present embodiment, since only one end of the tray 36 serves as a support point, and the identification plate 41 is a thin plate structure, excessive pressure may easily cause the identification plate 41 to deform, and the movable sheet 40 cannot be pressed too hard. Therefore, in the present embodiment, the pressure sensor 32 is used to detect the pressure of the suction cup 19 on the identification plate 41, and when the third drive motor 14 stops suddenly, the movement of the lifting rod 15 is buffered. Specifically, the tray 36 in the tray assembly 2 is rotated out, and the lifting rod 15 is driven down by the third drive motor 14, and the suction cup 19 approaches the identification plate 41 and contacts the identification plate 41, and the gas in the cavity of the suction cup 19 is squeezed and moves along The hollow tube in the connecting rod 30 enters the air storage chamber 42, and the gas in the air storage chamber 42 increases, causing the air storage chamber 42 to expand. At the same time, due to the support of the identification plate 41 in the tray 36 for the suction cup 19, the connecting rod 30 moves along the through groove of the lower fixed cylinder 29. The two work together to cause the protrusion 31 of the connecting rod 30 to move upward and contact the probe of the pressure sensor 32. After the probe of the pressure sensor 32 detects the set pressure signal, the third drive motor 14 stops driving the lifting rod 15 to descend. At the same time, the air pump 20 inhales air to suck out part of the gas in the air storage chamber 42 and the hollow tube, so that the suction cup 19 can firmly grasp the identification plate 41.

[0079] During the emergency stop of the third drive motor 14 , the lifting rod 15 is blocked by the damping wheel 43 of the damping member 26 , so that the cylinder 24 contacts the buffer block on the lifting rod 15 , thereby causing the lifting rod 15 to stop descending very stably.

[0080] This embodiment uses the first drive motor 11 and the second drive motor 12 as power input, so that the transfer assembly 3 transfers the identification plate 41 to the laser engraving machine 4, and then the third drive motor 14 drives the lifting rod 15 to continue to descend. After the identification plate 41 contacts the bearing area of ​​the laser engraving machine 4, the pressure sensor 32 receives the signal again because the identification plate 41 in the bearing area supports the suction cup 19. At this time, the air pump 20 inflates the hollow tube and the suction cup 19 to separate the suction cup 19 from the identification plate 41. The air pump 20 stops inflating, and the suction cup 19 moves downward under the action of gravity, and the gas in the air storage chamber 42 is discharged to the outside along the cavity of the hollow tube and the suction cup 19. The suction cup 19 falls back to its original position and is ready to grab the identification plate 41 again.

[0081] The control device in the local computer 5 is configured with information such as the suction and exhaust volumes of the air pump 20, the pressure detection threshold of the pressure sensor 32, the rotation angles of the output shafts of the first drive motor 11 and the second drive motor 12, and the rotation angle of the output shaft of the motor driving the tray 36 to rotate.

[0082] Example 3

[0083] This embodiment describes the loading of the identification plate 41 in the tray 36. There are at least two solutions for loading the identification plate 41 in this embodiment.

[0084] The first loading scheme is manual loading, that is, controlling the tray 36 to rotate out and placing the identification plate 41 in the tray 36. If a support seat 37 is installed in the tray 36, the upper movable sheet 40 is flipped upward, and then the identification plate 41 is placed on the horizontally placed movable sheet 40.

[0085] The second loading scheme is automatic loading, which uses a pushing device to push a single identification plate 41 to the loading area 6 of the base 1. According to the color of the identification plate 41, the tray 36 at the corresponding position is controlled to rotate out, and the identification plate 41 is pushed into the tray 36 from bottom to top using the push column 7. At this time, while the identification plate 41 is being pushed into the tray 36, the identification plate 41 pushes the movable sheet 40 to move upward. After the identification plate 41 is separated from the movable sheet 40, the movable sheet 40 falls back under the action of gravity, and the push column 7 descends to place the identification plate 41 on the movable sheet 40. The push column 7 relies on power such as an electric cylinder to achieve movement. The push column 7 is installed on the output shaft of the electric cylinder. After the identification plate 41 is placed in the tray 36, the pushing device pushes the next identification plate 41 into the loading area 6 and repeats the loading according to the color of the identification plate 41.
