Description

Technical Field

[0001] This invention relates to the field of factory marking equipment technology, and in particular to an automatic liquid replenishment base station, system and method for steel structure factory marking equipment. Background Technology

[0002] In 5A-level factories, floor markings are not merely for aesthetics, but also for improving production efficiency, ensuring workplace safety, and standardizing production processes. With increasing industrial automation, the demands for refined management of the production environment are also rising, making floor markings an increasingly important visual management tool on the production floor. Furthermore, with the development of intelligent manufacturing technologies, floor markings in 5A-level factories are also evolving towards intelligent and information-based approaches. For example, intelligent recognition technology can enable automatic monitoring and management of marked areas; and information systems can facilitate real-time updates and sharing of marking information. The application of these technologies will further enhance the factory's production efficiency and management level.

[0003] To reduce the waste of human resources, automated line marking equipment has emerged on the market, capable of marking ground lines according to a pre-set path. These automated line marking devices are highly efficient, significantly reducing the need for manual labor. However, these devices have some drawbacks, such as the need for manual replenishment of paint, preventing fully automated paint replenishment.

[0004] To achieve fully automated paint replenishment, workstations have emerged on the market that automatically replenish paint using a reservoir. However, these workstations also have drawbacks, such as the inability to accurately position the marking equipment, and the inability of the reservoir and marking equipment to effectively connect, leading to damage to the marking equipment interface and paint leakage.

[0005] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as the workstation's inability to accurately locate the marking equipment, the inability of the liquid storage tank and the marking equipment to effectively connect, and the damage to the liquid replenishment port of the marking equipment.

[0077] In some embodiments, the docking of the docking component with the automatic ground marking painting device includes:

[0078] The first driving component drives the support plate to move vertically upward, causing the automatic ground marking painting device to come into contact with the second pipe. As the automatic ground marking painting device moves upward, the second pipe extends and retracts along the axial direction of the first pipe. The movement of the second pipe drives the first moving component to move, and the first moving component drives the valve body to open, thus connecting the first pipe and the second pipe.

[0079] When the second pipe fitting is successfully connected to the automatic ground marking painting equipment, the first monitoring device is triggered and generates a connection success signal;

[0080] If the second pipe fitting fails to connect with the automatic ground marking painting equipment, the first monitoring component is not triggered and either fails to generate a connection failure signal or fails to generate a connection success signal.

[0081] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0082] This invention discloses an automatic liquid replenishment base station, system, and method for a ground marking equipment in a steel structure factory. By installing a positioning component on the lifting component, the positioning component can limit the automatic ground marking equipment when it moves onto the lifting component. This allows for high-precision automatic positioning of the relatively large automatic ground marking equipment, facilitating subsequent automatic liquid replenishment operations, improving positioning efficiency, and reducing positioning time. Furthermore, by installing a reflux component and a shaking component on the base component, the positioning component positions the automatic ground marking equipment onto the lifting component. Subsequently, the return component can automatically dock with the automatic road marking painting equipment, allowing the paint in the storage tank of the automatic road marking painting equipment to flow back into the storage component. The shaking component shakes the storage component to ensure uniform shaking. By setting a docking component on the base component, the operation of the lifting component can lift the automatic road marking painting equipment, allowing the liquid inlet on the automatic road marking painting equipment to dock with the docking component. This allows the storage component to supply paint to the automatic road marking painting equipment, thus completing the liquid filling operation of the automatic road marking painting equipment.

[0109] In some embodiments, there are multiple first support members 1201. The multiple first support members 1201 are distributed along the length and / or width direction of the base member 1100.

[0110] In some embodiments, there are two first support members 1201, and the two first support members 1201 are spaced apart along the length direction of the base member 1100, that is, the two first support members 1201 correspond to the two sides of the support plate member 1208 in the width direction respectively.

[0111] It should be noted that the number of first guide members 1202 matches the number of first support members 1201. It should be understood that the number of first guide members 1202 is an integer multiple of the number of first support members 1201. Generally, the number of first guide members 1202 is twice the number of first support members 1201. That is, each first support member 1201 is provided with two first guide members 1202, and the two first guide members 1202 are symmetrically arranged on the first support member 1201.

[0112] Specifically, the first guide member 1202 is configured with a circular hole structure.

[0119] In some of these embodiments, the first drive element 1204 includes, but is not limited to, a motor.

[0120] It should be noted that the number of first driving components 1204 matches the number of lead screw components 1203. It should be understood that the number of first driving components 1204 is the same as the number of lead screw components 1203.

[0121] It should be noted that the number of moving parts 1205 is matched with the number of lead screw parts 1203. It should be understood that the number of moving parts 1205 is twice the number of lead screw parts 1203. That is, each lead screw part 1203 is provided with two moving parts 1205, and the two moving parts 1205 are symmetrically arranged on the lead screw part 1203.

[0122] Specifically, one moving part 1205 is threaded through the first threaded section of the lead screw 1203 and connected by threads, and another moving part 1205 is threaded through the second threaded section of the lead screw 1203 and connected by threads. That is, the rotation of the lead screw 1203 can drive the two moving parts 1205 to move toward each other or away from each other.

[0123] In some embodiments, the movable element 1205 includes, but is not limited to, a movable block.

[0124] It should be noted that the number of second guide members 1206 is matched with the number of moving members 1205. It should be understood that the number of second guide members 1206 is an integer multiple of the number of moving members 1205. Generally, the number of second guide members 1206 is twice the number of moving members 1205. That is, each moving member 1205 is provided with two second guide members 1206, and the two second guide members 1206 are symmetrically arranged on the moving member 1205.

[0125] Specifically, for each movable component 1205, two second guide components 1206 are respectively set on both sides of the width direction of the movable component 1205 by means of welding, bolt fixing or integral molding, etc. The second guide components 1206 pass through the first guide components 1202 on both sides of the width direction of the first support component 1201 to restrict the rotation direction of the movable component 1205, so that the movable component 1205 moves in the horizontal direction.

The control component 1802 is located on the base component 1100 and is connected to the liquid storage component 1400, the shaking component 1500, the reflux component 1600, and the positioning component 1700, respectively, for controlling the start and stop of the liquid storage component 1400, the shaking component 1500, the reflux component 1600, and the positioning component 1700.

[0230] Specifically, the communication component 1801 is installed on the base component 1100 by means of welding, riveting or bolting, and the communication component 1801 is connected to the external remote control device, the first monitoring component 1307, the second monitoring component 1404 and the third monitoring component 1604 by means of wired connection or wireless connection.

[0231] In some embodiments, the communication device 1801 includes, but is not limited to, a Bluetooth sensor, a WiFi sensor, and a ZigBee sensor.

[0232] Specifically, the control component 1802 is installed on the base component 1100 by means of welding, riveting or bolting, and the control component 1802 is connected to the communication component 1801, the first drive component 1204, the pump body component 1402, the shaking component 1501, the reflux component 1602 and the second drive component 1702 by means of wired connection, etc., and is used to control the start and stop of the first drive component 1204, the pump body component 1402, the shaking component 1501, the reflux component 1602 and the second drive component 1702.

[0233] In some of these embodiments, the controller 1802 includes, but is not limited to, an MCU, a Raspberry Pi, or a microcontroller.

[0234] The usage method of this embodiment is as follows:

[0235] In actual operation, the automatic ground marking painting equipment moves onto the support plate 1208. Subsequently, the control unit 1802 starts the second drive unit 1702. The second drive unit 1702 drives the first positioning unit 1704 and the second positioning unit 1705 to position the walking wheels of the automatic ground marking painting equipment, thereby enabling the automatic ground marking painting equipment to dock with the return component 1600.

[0236] Then, the control unit 1802 activates the return unit 1602, which can return the residual paint from the automatic ground marking painting equipment to the inside of the liquid storage unit 1401 through the fourth pipe 1601 and the fifth pipe 1603.

[0237] Subsequently, the control unit 1802 starts the shaking unit 1501, which drives the liquid storage unit 1401 to shake, thereby making the paint liquid inside the liquid storage unit 1401 shake evenly, which is convenient for subsequent spraying operations.

[0238] Finally, the control unit 1802 activates the first drive unit 1204, which drives the support plate 1208 to rise, thereby connecting the liquid inlet of the automatic ground marking painting equipment and activating the pump 1402 inside the liquid storage unit 1401. The pump 1402 pumps the paint inside the liquid storage unit 1401 to the first pipe 1302, and then delivers the paint to the liquid storage tank of the automatic ground marking painting equipment through the second pipe 1303, thus completing the liquid replenishment operation of the automatic ground marking painting equipment.

[0239] The advantages of this embodiment are as follows: By setting a positioning component on the lifting component, the automatic road marking painting equipment can be limited when it moves onto the lifting component. This allows for high-precision automatic positioning of the larger automatic road marking painting equipment, facilitating subsequent automatic liquid addition operations, improving positioning efficiency, and reducing positioning time. By setting a return component and a shaking component on the base component, after the positioning component positions the automatic road marking painting equipment on the lifting component, the return component can automatically dock with the automatic road marking painting equipment, allowing the paint in the storage tank of the automatic road marking painting equipment to flow back into the storage component. The shaking component agitates the storage component, ensuring uniform shaking within it. By setting a docking component on the base component, the operation of the lifting component can lift the automatic road marking painting equipment, allowing the liquid inlet on the automatic road marking painting equipment to dock with the docking component. This enables the storage component to supply paint to the automatic road marking painting equipment, thus completing the liquid addition operation.

[0240] Example 2

[0241] This embodiment is a modified embodiment of embodiment 1. The difference between this embodiment and embodiment 1 is that the automatic liquid replenishment base station 1000 also includes a heating component 1900.

[0242] like Figure 8 As shown, the automatic liquid replenishment base station 1000 also includes a heating component 1900. The heating component 1900 is located at the docking point between the docking component 1300 and the automatic ground marking painting device, and is connected to the control component 1800. It is used to heat the docking component 1300 to prevent the paint from solidifying and forming a blockage.

[0243] like Figure 9 and Figure 10As shown, the heating component 1900 includes a heating sleeve 1901 and a limiting component 1902. The heating sleeve 1901 is fitted onto the first end of the docking component 1300 and connected to the control component 1800, used to heat the docking component 1300 to prevent the paint from solidifying and causing blockage. The limiting component 1902 is disposed at the second end of the docking component 1300, used to fix the position of the heating sleeve 1901 and the docking component 1300.

[0244] Specifically, the heating sleeve 1901 is fitted onto the first pipe 1302, and the heating sleeve 1901 can heat the paint liquid in the first pipe 1302 through heat conduction, thereby facilitating the subsequent marking operation of the automatic ground marking equipment.

[0245] In some of these embodiments, the heating sleeve 1901 includes, but is not limited to, a heating wire.

[0246] Specifically, the limiting member 1902 is installed on the first pipe 1302 by means of welding, riveting or bolting, and the limiting member 1902 can restrict the heating sleeve 1901.

[0247] In some embodiments, the limiting member 1902 includes, but is not limited to, an annular plate.

[0248] The usage method of this embodiment is the same as that of Embodiment 1, and no further restrictions are imposed here.

[0249] The advantage of this embodiment is that by setting a heating component on the docking component, the heating component can heat the paint liquid in the pipe of the docking component, thereby facilitating the subsequent painting operation of the automatic ground marking painting equipment.

[0250] Example 3

[0251] This embodiment is a modified embodiment of Embodiments 1-2. The difference between this embodiment and Embodiments 1-2 is that the automatic liquid replenishment base station 1000 also includes a charging component.

[0252] The automatic liquid replenishment base station 1000 also includes a charging component. The charging component is located on the lifting component 1200 and connected to the control component 1800, and is used to supply power to the automatic ground marking painting equipment.

[0253] Specifically, the charging component is installed on the base component 1100 by means of welding, riveting or bolting. When the positioning component 1700 completes the positioning of the automatic ground marking painting equipment, the charging component can dock with the automatic ground marking painting equipment, thereby enabling the charging component to supply power to the automatic ground marking painting equipment.

[0254] In some embodiments, the charging component includes, but is not limited to, a charging connector.

[0255] The usage method and advantages of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

[0256] Example 4

[0257] This embodiment relates to the automatic ground marking system of the present invention.

[0258] like Figure 11 As shown, an automatic ground marking painting system for steel structure factory marking equipment includes an automatic liquid replenishment base station 1000 and an automatic ground marking painting device 2000 as described in Examples 1 to 3. When the paint level in the automatic ground marking painting device 2000 is lower than a preset low level threshold, the automatic ground marking painting device 2000 moves to the base component 1100, is positioned by the positioning component 1700, and docks with the docking component 1300, so that the docking component 1300 replenishes the paint to the automatic ground marking painting device 2000.

[0259] Specifically, the automatic ground marking painting device 2000 is connected to the control unit 1800 for real-time communication with the automatic liquid replenishment base station 1000.

[0260] Example 5

[0261] This embodiment relates to the automatic fluid replenishment method of the present invention.

[0262] Figure 12 This is a flowchart (a) of an automated fluid resuscitation method according to an embodiment of the present invention. Figure 12 As shown, an automatic liquid replenishment method for steel structure factory marking equipment, applied to the automatic liquid replenishment base station 1000 as described in Examples 1-3 or the automatic ground marking painting system as described in Example 4, includes:

[0263] Step S1201: When the automatic ground marking painting equipment 2000 enters the lifting component 1200, the positioning component 1700 performs a positioning process on the automatic ground marking painting equipment 2000.

[0264] Step S1202: After the positioning process is completed, the return component 1600 is connected to the drain pipe of the automatic ground marking painting equipment 2000 to carry out the return process;

[0265] Step S1203: After the reflow process is completed, the lifting component 1200 drives the automatic ground marking painting equipment 2000 to perform the rising process;

[0266] Step S1204: After the lifting process is completed, the docking component 1300 is docked with the automatic ground marking painting equipment 2000.

[0267] Step S1205: After the docking process is completed, the docking component 1300 performs a paint delivery process to the automatic ground marking painting equipment 2000;

[0268] Step S1206: After the paint delivery process is completed, the docking component 1300 separates from the automatic ground marking painting equipment 2000, and the lifting component 1200 drives the automatic ground marking painting equipment 2000 to perform a lowering process.

[0269] Step S1207: After the descent process is completed, the automatic ground marking painting equipment 2000 leaves the lifting component 1200.

[0270] In step S1201, the automatic ground marking painting device 2000 enters the lifting component 1200, including the following situations:

[0271] The battery level of the automatic road marking painting equipment 2000 has reached the battery warning threshold; and / or

[0272] The paint level of the 2000 automatic ground marking painting equipment has reached the level warning threshold.

[0273] In some embodiments, step S1204 includes:

[0274] If the docking component 1300 fails to dock with the automatic ground marking painting device 2000, the docking component 1300 will separate from the automatic ground marking painting device 2000.

[0275] After the docking component 1300 has separated from the automatic ground marking painting equipment 2000, the positioning component 1700 separates from the automatic ground marking painting equipment 2000.

[0276] The automatic ground marking painting equipment 2000 leaves the lifting component 1200 and repeats the above steps.

[0277] Figure 13 This is a flowchart (II) of an automatic fluid replenishment method according to an embodiment of the present invention. Figure 13 As shown, the positioning component 1700 positions the automatic ground marking painting device 2000, including:

[0278] Step S1301: The second driving component 1702 drives the mounting bracket component 1703 to move towards the automatic ground marking painting device 2000;

[0279] In step S1302, when the second driving component 1702 drives the mounting bracket component 1703 to reach the preset positioning position, the first positioning components 1704 located on both sides of the automatic ground marking painting device 2000 respectively engage with the front traveling wheel of the automatic ground marking painting device 2000 and perform a front-to-back positioning process on the traveling wheel, and the second positioning components 1705 located on both sides of the automatic ground marking painting device 2000 respectively abut against the rear traveling wheel of the automatic ground marking painting device 2000 and perform a left-to-right positioning process on the traveling wheel.

[0280] In step S1301, the preset positioning position refers to the position set by the control component 1800. When the position is reached, the second drive component 1702 stops operating.

[0281] In step S1302, the first positioning members 1704 located on both sides of the automatic ground marking painting device 2000 are connected to the axles of the rear walking wheels of the walking unit to limit the front and rear positions of the rear walking wheels, thereby positioning the front and rear positions of the automatic disinfection robot device.

[0282] The second clamping elements located on both sides of the automatic disinfection robot device are respectively engaged with the front wheels of the automatic ground marking painting device 2000 to restrict the left and right positions of the front wheels, thereby positioning the left and right positions of the automatic ground marking painting device 2000.

[0283] Compared with related technologies, steps S1301 to S1302 simultaneously perform front-to-back and left-to-right positioning on the automatic ground marking painting equipment 2000, thereby achieving 5mm high-precision positioning, greatly reducing positioning time, improving positioning efficiency, and avoiding repeated entry and exit of the automatic ground marking painting equipment 2000 from the lifting component 1200.

[0284] In some embodiments, positioning the automatic ground marking painting device 2000 by the positioning component 1700 further includes:

[0285] If the docking component 1300 fails to dock with the automatic ground marking painting device 2000, the second driving component 1702 drives the mounting bracket component 1703 away from the automatic ground marking painting device 2000.

[0286] When the second driving component 1702 drives the mounting bracket component 1703 to reach the initial position, the first positioning components 1704 located on both sides of the automatic ground marking painting device 2000 separate from the front wheels of the automatic ground marking painting device 2000, and the second positioning components 1705 located on both sides of the automatic ground marking painting device 2000 separate from the rear wheels of the automatic ground marking painting device 2000.

[0287] Figure 14This is a flowchart (III) of an automated fluid replenishment method according to an embodiment of the present invention. Figure 14 As shown, the connection between the docking component 1300 and the automatic ground marking painting device 2000 includes:

[0288] In step S1401, the first driving component 1204 drives the support plate 1208 to move upward in the vertical direction, so that the automatic ground marking painting device 2000 abuts against the second pipe 1303. As the automatic ground marking painting device 2000 moves upward, the second pipe 1303 extends and retracts along the axial direction of the first pipe 1302. The movement of the second pipe 1303 drives the first moving component 1306 to move. The first moving component 1306 drives the valve body 1305 to open, realizing the connection between the first pipe 1302 and the second pipe 1303.

[0289] Step S1402: When the second pipe fitting 1303 is successfully connected to the automatic ground marking painting device 2000, the first monitoring component 1307 is triggered and a connection success signal is generated.

[0290] In step S1403, if the second pipe fitting 1303 fails to connect with the automatic ground marking painting device 2000, the first monitoring component 1307 is not triggered and a connection failure signal is generated or a connection success signal is not generated.

[0291] Furthermore, after step S1402, the following steps are also included:

[0292] The control unit 1800 controls the liquid storage unit 1400 to deliver disinfectant to the docking unit 1300.

[0293] Furthermore, after step S1402, the following steps are also included:

[0294] When the first monitoring element 1307 is triggered, the first driving element 1204 stops driving and maintains its current state;

[0295] When the paint in the automatic ground marking painting equipment 2000 is replenished, the first drive component 1204 drives the support plate component 1208 to move downward in the vertical direction, so that the second pipe component 1303 is separated from the automatic ground marking painting equipment 2000.

[0296] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0297] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
