Description

Technical Field

[0001] The present application belongs to the field of laser etching technology, and in particular relates to an all-in-one machine for storing, transporting and marking signboards. 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 identification plates are urgently needed but have not been marked. For example, during the inspection process, the inspection personnel find that the identification plates need to be replaced. They can only record them and return to the unit for operation and marking. If the identification plates can be transferred and marked remotely on site, not only can the identification plate information be directly input according to the on-site situation, but the urgently needed identification plates 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 are beginning to introduce automated equipment to replace manual operations. The management of power grid facilities is also gradually introducing these technologies to improve the efficiency and accuracy of identification work.

[0005] Different colored signboards are used in different power equipment or environments. Currently, the marking of signboards is usually completed through on-site manual handling and marking. 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 all completed manually.

[0006] In addition, automated signboard transfer usually involves grabbing the signboards from top to bottom through a grabbing structure. Signboards are thin plate structures. If the grabbing force is too small, the signboards are likely to fall off. If the grabbing force is too large, the signboards are likely to deform. Flat signboards take up a large space, and stacked signboards are prone to signboard adhesion problems caused by heavy pressure, friction, static electricity, and environmental factors.

[0007] Therefore, the development of an all-in-one signboard storage, transfer and marking machine 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.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1. This application utilizes a remote intelligent terminal to connect to a local computer through a cloud server, and controls the operation of the pallet assembly, transfer assembly, and laser engraving machine to achieve remote marking of signboards. When inspectors are on patrol outside, they can output control instructions through the intelligent terminal and remotely control the printing of the required signboards, reducing waiting time when signboards are urgently needed.

[0028] 2. This application uses the transfer assembly to grab the identification plates in the pallet.

The pallets in the pallet assembly are rotated out, and the identification plates of the corresponding colors can be grabbed as needed. The solution of grabbing with multiple suction cups is adopted, and the grabbing is stable.

[0029] 3. When the grasping component of the present application grasps the identification plate, the suction cup is squeezed so that the gas enters the gas storage chamber along the hollow tube. The amount of gas in the gas storage chamber increases, and with the support of the identification plate, the protrusion contacts the pressure sensor, so that the grasping component grasps the identification plate with the same appropriate force. The gas storage chamber ensures that the protrusion moves in a straight line and stably contacts the probe, avoiding inaccurate detection caused by the protrusion falling back after contacting the probe.

[0030] 4. When the motor that drives the lifting rod to move stops suddenly after grabbing the signboard, the present application utilizes the damping member, buffer block, spring and other structures in contact with the lifting rod to prevent the lifting rod from moving by the damping wheel of the damping member, so that the cylinder contacts the buffer block on the lifting rod, thereby causing the lifting rod to stop its descending movement very stably, avoiding the situation where the lifting rod continues to fall for a certain distance and the protrusion contacts the probe excessively, resulting in inaccurate detection.

[0031] 5. The tray of the present application is provided with movable plates that can rotate upward but cannot rotate downward to support and separate the identification plates in the tray to prevent the identification plates from sticking together. It also enables the top column of the loading area to push the identification plates into the tray from bottom to top, thereby realizing automatic loading of the identification plates.

The material of the identification plate 41 includes metal, plastic, etc. The surface of the metal identification plate 41 needs to be sprayed with paint in advance for rust prevention.

[0054] The integrated machine for storing, transferring and marking signboards of this embodiment includes a signboard storage and transfer machine, a laser engraving machine 4, a local computer 5, a cloud server 9 and an intelligent terminal 8. The intelligent terminal 8 includes but is not limited to a smart phone, a tablet computer, etc. The signboard storage and transfer machine of this embodiment includes a base 1. A pallet assembly 2 is installed on one side of the base 1, and a transfer assembly 3 is installed on the other side of the base 1.

There are no less than two pallets 36 in the pallet assembly 2. For example, the specific number of pallets 36 in this embodiment is five, and each pallet 36 is used to carry signboards 41 of different colors. The transfer assembly 3 grabs the signboard 41 in the pallet 36 and transfers it to the laser engraving machine 4. The laser engraving machine 4 prints text, graphics and numbers on the signboard 41, and then the transfer assembly 3 grabs the marked signboard 41 from the laser engraving machine 4.

[0055] In this embodiment, the electrical power components in the pallet assembly 2 and the transfer assembly 3, the laser engraving machine 4 and the controller in the local computer 5 are electrically connected, and the smart terminal 8 is connected to the local computer 5 through the cloud server 9. The smart terminal 8 or the local computer 5 controls the operation of the pallet assembly 2, the transfer assembly 3 and the laser engraving machine 4.

[0056] Specifically, the intelligent terminal 8 has a management system, which is used to generate corresponding tray rotation control instructions according to the input operation and send the tray rotation control instructions to the cloud server 9. The cloud server 9 is used to receive the tray rotation control instructions sent by the management system and send the tray rotation control instructions to the local computer 5;

[0057] The management system is used to generate corresponding transfer control instructions according to the input operation, and send the transfer control instructions to the cloud server 9. The cloud server 9 is used to receive the transfer control instructions sent by the management system and send the transfer control instructions to the local computer 5.

[0058] The management system is used to generate corresponding marking control instructions according to the input operation, and send the marking control instructions to the cloud server 9. The cloud server 9 is used to receive the marking control instructions sent by the management system and send the marking control instructions to the local computer 5.

[0059] The cloud server 9 also has a database. The management system can directly retrieve the information stored in the database in the cloud server 9 and send the information to the laser engraving machine 4 through the management system. The information includes the license plate template, number, name, etc.

[0060] This embodiment adopts an ARM chip and connects to the local computer 5 through the TCP network port serial port communication. By adding a VPN, it can also be directly connected to the APP on the smart terminal 8. As the local computer 5 control, the laser engraving machine 4 is directly connected through the local computer 5. By setting a fixed template, the required modification content is input into the template fixed parameter setting. After the setting is completed, confirm printing, and the corresponding content can be directly printed. As the APP control in the remote smart terminal 8, the fixed template is set through the APP, and the required modification content is input into the fixed template fixed parameter setting. After the setting is completed, confirm printing, and the corresponding content can be directly printed.

[0061] The transfer assembly 3 of this embodiment includes a movable arm, on which a grabbing assembly is installed, and a lifting component capable of lifting and lowering motion is provided in the grabbing assembly, and a grabbing component is installed on the lifting component. As a specific structure, the movable arm of this embodiment is a three-section structure, and 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 the 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 the main body of the second drive motor 12 is fixed on the first shell 17, and a lifting component is installed in the first shell 17, 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 the lifting component is fixed on the fixed bracket 13. The lifting component includes a guide rail 16, a moving block 22 that moves 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 lower end of which is equipped with a suction cup 19, 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 the driving wheels at different positions through a rack, chain or belt. Correspondingly, the rotating wheel and the driving wheel are respectively a type of gear, sprocket, and 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. Bearings 35 are installed between the sleeves, and each sleeve is equipped with a rotating wheel, and the rotating wheels are arranged along the height direction of the support rod 34.

[0066] Each tray 36 of this embodiment can hold an identification plate 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 embodiment 1.

[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 downward rotation of the movable plate 40. 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, and 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 fixing cylinder of the grabbing component includes an upper fixing cylinder 27, a lower fixing cylinder 29 and a side fixing cylinder 28. The side fixing cylinder 28 is arranged on one side of the upper fixing cylinder 27, and the lower fixing cylinder 29 is arranged at the lower end of the upper fixing cylinder 27. As a connection scheme, the lower fixing cylinder 29 and the upper fixing cylinder 27 are connected together by threads.

[0073] A pressure sensor 32 is installed in the upper fixed cylinder 27. The pressure sensor 32 is screwed to 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 a thread.

[0074] The present application uses at least two suction cups 19 to avoid the problem of instability when a single suction cup 19 grabs 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 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 passed through 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, the present embodiment further arranges an air storage chamber 42 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 prevent inaccurate detection caused by this, as an implementation scheme, the air storage chamber 42 is two contact sleeves, referred to herein as an upper sleeve and a lower sleeve. The sleeves are rigid structural parts, and a sealing arrangement is provided between the two contact sleeves to avoid air leakage. The upper sleeve can move along the lower sleeve, and 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 the air supply pipe 33, and the air pump 20 and the compressed suction cup 19 control the amount of gas inside the hollow tube and the air storage chamber 42.

[0076] In addition, based on this, in order to avoid the problem 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, and then causing the pressure sensor to detect excessive floating, this embodiment has a damping member 26 installed on the lifting assembly. Specifically, a damping wheel 43 is installed in the damping member 26. The damping wheel 43 contacts the surface of the lifting rod 15, so that the lifting rod 15 drives the damping wheel 43 to rotate during the ascent or descent process, thereby avoiding 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 inwardly concave arc area, and the arc area contacts 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 fixed plate 23 is installed on the moving block 22. The fixed plate 23 is L-shaped. A part of the fixed plate 23 is connected to the moving block 22. The other part of the fixed plate 23 has a through hole. The lifting rod 15 passes through the through hole. The head end of the lifting rod 15 is installed with a cylinder 24. The cylinder 24 and the lifting rod 15 are clearance-fitted, that is, the lifting rod 15 can move inside the cylinder 24. A buffer block is installed at the top end of the lifting rod 15. The buffer block is fixedly connected to the lifting rod 15. A spring 25 is arranged between the lower end of the cylinder 24 and the fixed 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 moves temporarily, the lifting rod 15 can move slightly within the compressible range of the spring 25.

[0078] In this embodiment, since the tray 36 has only one end as a support point, and the identification plate 41 is a thin plate structure, excessive pressure can easily cause the identification plate 41 to deform, and the movable plate 40 cannot be pressed too hard. Therefore, in this 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. The suction cup 19 approaches the identification plate 41 and contacts the identification plate 41. 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 on the suction cup 19, the connecting rod 30 moves along the through groove of the lower fixed cylinder 29. The two work together to make the protrusion 31 of the connecting rod 30 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 sucks air out, sucking 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 support of the suction cup 19 by the identification plate 41 in the bearing area causes the pressure sensor 32 to receive the signal again. At this time, the air pump 20 inflates the hollow tube and the suction cup 19, so that the suction cup 19 is separated 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 volume of the air pump 20, the pressure detection threshold of the pressure sensor 32, the rotation angle of the output shaft of the first drive motor 11 and the second drive motor 12, and the rotation angle of the output shaft of the motor that drives 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 plate 40 is flipped upward, and then the identification plate 41 is placed on the horizontally placed movable plate 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 the bottom to the top using the push column 7. At this time, when the identification plate 41 is pushed into the tray 36, the identification plate 41 pushes the movable piece 40 to move upward. After the identification plate 41 is separated from the movable piece 40, the movable piece 40 falls back under the action of gravity, and the push column 7 descends, placing the identification plate 41 on the movable piece 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.
