The embodiment of the application provides a caulking robot, which can replace the construction mode of completely depending on the manpower work of workers in the traditional caulking operation, and realize the full-automatic unmanned high-efficiency caulking operation. The caulking robot mainly comprises a mobile chassis, an electric cabinet, a material storage device, a manipulator, an end executive part (namely, the end executive part; of course, when the end executive part is a robot of other types, the end executive part corresponds to an executive device of other types, such as when the end executive part is a grinding robot, the end executive part corresponds to a grinding executive part) and a stirring and cleaning system, wherein the stirring and cleaning system comprises a material stirring device 10, a cleaning device 20 and some auxiliary devices.
The movable chassis is used for providing walking power, so that the caulking robot has maneuvering operation capability, and is convenient for replacing different construction operation places. The movable chassis is also provided with a vibration damping system to improve the trafficability of the caulking robot and ensure the caulking precision and flatness during in-place work. In addition, the moving chassis is also provided with traveling parts such as universal wheels, idle wheels and the like, so that the moving chassis has the capabilities of omnidirectional movement and zero turning radius traveling, and meets various complex space and terrain working requirements.
The material storage device is used for storing various materials required by the preparation of the joint mixture, such as joint mixture raw material powder, water and the like. The joint mixture mentioned in the scheme is also called joint pointing agent, joint beautifying agent, joint filling material, joint beautifying paste and the like. For example, materials suitable for filling joints between ceramic tiles are collectively referred to as ceramic tile caulk. Most of the caulking agents currently used in the market are mainly cement-based caulking agents, and the cement-based caulking agents are prepared by mixing hydraulic cementing materials, such as cement, mineral aggregates, and organic and/or inorganic materials, in a certain proportion to form a uniform powder mixture, and the uniform powder mixture is mixed with water or other liquids to be used when preparing finished products of the caulking agents. It is noted that such caulks react to form a solid mass upon contact with water, and thus the finished caulk product is typically required to be used within 1 hour to avoid deterioration and loss of caulk properties.
The tail end executing piece is an executing mechanism for directly executing the joint filling operation, obtains higher degree of freedom by being connected with the mechanical arm, can execute the track movement such as straight line and curve, and meets the joint filling requirements of brick joints with various shapes, angles and the like. In the present embodiment, the end effector is formed as a piston-cylinder structure, i.e. comprising a cylinder, a piston, a nozzle, a drawing power mechanism, etc. The cylinder barrel is used for containing the caulking agent, and the drawing power mechanism pushes the piston to move, so that the caulking agent in the cylinder barrel can be extruded and discharged from the nozzle to a brick joint, and the caulking operation is completed. When the gap filler is used up after a period of operation, the manipulator moves the end executive part to extend into the material stirring device 10, the drawing power mechanism pulls the piston, suction force is generated in the cylinder barrel to suck the gap filler prepared in the material stirring device 10 into the cylinder barrel, material supplementing is achieved, and the end executive part has continuous working capacity. Just because the end effector needs to stretch into the caulking agent of the material stirring device 10 to reliably complete reliable material supplementing, the outer cylinder wall of the cylinder barrel is directly infected with the caulking agent, if the caulking agent infected from the outside is not cleaned, the part of the caulking agent is easily dropped accidentally during caulking operation, so that the quality problems of uneven and uneven caulking are caused or the construction environment is polluted. Therefore, before the completion of the filling and the formal filling operation, the cleaning device 20 is needed to clean the excess filling agent stained on the outer cylinder wall.
Referring to fig. 1 and 6, an agitation cleaning system according to an embodiment of the present application includes: a material stirring device 10 and a cleaning device 20. The material stirring device 10 comprises a stirring cylinder 11 and a stirring executing mechanism 12 connected with the stirring cylinder 11, wherein the stirring executing mechanism 12 is used for automatically and uniformly stirring the material in the stirring cylinder 11; the cleaning device 20 comprises a cleaning water tank 21 and a cleaning executing mechanism 22 arranged on the cleaning water tank 21, wherein the cleaning executing mechanism 22 is used for cleaning and removing materials stained on the end executing piece.
In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the stirring and cleaning system is applied to a gap filling robot and is mainly used for preparing gap fillers, supplying the gap fillers and cleaning redundant gap fillers for the tail end executive part, so that the manpower participation degree in the gap filling operation process is reduced, and the purposes of quality improvement and efficiency improvement are achieved. Specifically, before the caulking operation is performed, the mixing cylinder 11 is first filled with a certain amount of hydraulic binder (i.e., solid powder of caulking agent) and water (or other liquid), and the mixing actuator 12 is then activated to automatically mix the mixture uniformly, without human intervention. Then, the mechanical arm drives the end effector to move into the stirring cylinder 11 to fill the gap filler in a suction manner, and then the mechanical arm drives the end effector to extend into the cleaning water tank 21, and the cleaning actuator 22 can clean and remove the excess gap filler stained on the end effector in the extending process, so as to prevent the excess gap filler from dropping in the gap filling operation process to affect the gap filling quality. Therefore, in the three links of gap filler preparation, gap filler supply and redundant gap filler cleaning, the whole process does not need the intervention of workers, the increase of labor cost caused by high labor intensity can be greatly reduced, meanwhile, the automation degree of each mechanical structure is high, the coordination degree is high, the time consumed by operation can be greatly reduced, and the gap filling operation efficiency is improved.
Referring to fig. 1, 3-5, as mentioned above, the caulking compound has a hydraulic gelling property, so that after a certain period of operation, the inner wall of the mixing cylinder 11 is inevitably scaled by the caulking compound, and the mixing cylinder 11 needs to be cleaned periodically to avoid contamination of the caulking compound prepared later and interference with the operation of the mixing actuator 12. Based on this, in some embodiments, the stirring actuator 12 includes a stirring actuator 121 rotatably disposed in the stirring barrel 11, a stirring shaft 122 connected to the stirring actuator 121, a driving shaft 123, and a power assembly 124 connected to the driving shaft 123, one of the stirring shaft 122 and the driving shaft 123 is provided with a locking portion 122a, the other of the stirring shaft 122 and the driving shaft 123 is provided with a locking portion 123a, and the locking portion 122a is detachably engaged with the locking portion 123 a. When the gap filler is prepared, the power assembly 124 drives the driving shaft 123 to rotate, the driving shaft 123 limits the rotation freedom degree of the stirring shaft 122 in the Z-axis direction through the clamping of the clamping body 122a and the clamping position 123a, so that the driving shaft 123 can synchronously drive the stirring shaft 122 to rotate, and the stirring shaft 122 finally drives the stirring execution assembly 121 to rotate to complete the uniform stirring of the mixed raw materials in the stirring barrel 11. However, the engaging structure of the engaging body 122a and the engaging position 123a does not limit the freedom of movement in the Z-axis direction of the driving shaft 123, so that when the stirring cylinder 11 needs to be cleaned, the stirring rod can be directly pulled out and separated from the driving shaft 123, and the stirring cylinder 11 can be detached separately, thereby facilitating cleaning. The structure is simple, the connection reliability is high, and the assembly and disassembly are convenient.
Specifically, in the above embodiment, the block 122a is a flat block formed at the end of the stirring shaft 122, and the block 123a is a slot formed at the top end of the driving shaft 123, and the flat block can be inserted and fixed in the slot. In order to avoid assembly interference, the depth of the clamping groove needs to be slightly larger than the height of the flat block, namely, a gap can be formed between the clamping groove and the flat block after the clamping groove and the flat block are assembled.
The stirring cylinder 11 is formed into a cylindrical cylinder with an open upper end, and a through hole is formed in the middle of the bottom wall of the stirring cylinder 11 so that the stirring shaft 122 can penetrate out and can be inserted into the driving shaft 123. Particularly, a bearing seat and a sealing element are arranged between the stirring shaft 122 and the through hole, so that the sealing capability of the assembly part can be improved while the stirring shaft 122 is ensured to rotate reliably, and the gap filler in the stirring barrel 11 is prevented from leaking out of the through hole.
Referring to fig. 3, in some embodiments, the stirring executing assembly 121 includes a carrying rod 121a connected to the stirring shaft 122, and a first stirring rod 121b and a second stirring rod 121c disposed at opposite ends of the carrying rod 121a at intervals, wherein both the first stirring rod 121b and the second stirring rod 121c are abutted against or in clearance fit with the inner wall of the stirring cylinder 11. So, (mixing) shaft 122 is rotatory can drive and carry pole 121a synchronous rotation, carries pole 121a and then can drive first puddler 121b and second puddler 121c rotatory, because first puddler 121b and second stirring are arranged along the axial extension of stirring feed cylinder 11, therefore the mixed material in the stirring feed cylinder 11 that can be fine, realizes the purpose that the even stirring of gap filler was made. And the first stirring rod 121b and the second stirring rod 121c can be abutted against the inner wall of the stirring cylinder 11 according to the working requirement, so that the inner wall can be scraped, and the gap filler can be prevented from being condensed on the wall surface and remaining to cause the waste of the gap filler.
In order to ensure the service life, the first stirring rod 121b, the second stirring rod 121c and the stirring cylinder 11 are made of metal materials under normal conditions, so that the service life is reduced and noise is generated to influence the use experience of the caulking robot in order to avoid friction and abrasion generated when the first stirring rod 121b and the second stirring rod 121c rotate relative to the stirring cylinder 11. In some embodiments, the stirring implement assembly 121 further includes a first soft scraper 121d and a second soft scraper 121e, the first soft scraper 121d is disposed on the first stirring rod 121b, the second soft scraper 121e is disposed on the second stirring rod 121c, and both the first soft scraper 121d and the second soft scraper 121e are abutted against the inner wall of the stirring cylinder 11. Through the soft scraper blade 121d of the first soft scraper blade 121d of installation and the soft scraper blade 121e of second, can make the automatic inner wall that closely laminates stirring feed cylinder 11 of stirring executive component 121 rotate, fully hang down the joint mixture of gluing on avoiding but do not harm the inner wall of stirring feed cylinder 11 simultaneously again, noise abatement produces, can be fine compromise scrape material, life and use experience the tripartite demand, further promote joint filling robot's performance and reliability.
It is understood that the material used for the first soft scraper 121d and the second soft scraper 121e can be, but is not limited to, rubber, plastic, etc.
Generally, in order to ensure the efficiency and quality of the gap filler preparation, the rotation speed of the first stirring rod 121b and the second stirring rod 121c is high, and since the first stirring rod 121b and the second stirring rod 121c are arranged close to the cylinder wall away from the center of the stirring cylinder 11, the mixture in the stirring cylinder 11 is very likely to generate a vortex phenomenon under the condition of high-speed rotation, which is not favorable for the sufficient and uniform mixing of the mixture. In contrast, in some embodiments, the length of the first stirring rod 121b is greater than the length of the second stirring rod 121 c; or the length of the second agitating shaft 121c is greater than the length of the first agitating shaft 121 b. That is, the rod lengths of the first stirring rod 121b and the second stirring rod 121c are designed to have a difference, so that even when the first stirring rod 121b and the second stirring rod 121c rotate at a high speed, since the stirring forces generated to the mixture are different, no vortex is generated, the flow capability of the mixture can be ensured, and the stirring effect is good. In particular, the effective working time of the caulking agent which has high viscosity and density and is easy to solidify can be prolonged, and the phenomenon that the caulking agent is easy to generate agglomeration due to uneven distribution in the stirring charging barrel 11 can be prevented.

Specifically, the stirring bracket 125 is installed at the bottom of the stirring cylinder 11, and plays a good role in bearing and fixing the stirring cylinder 11 by virtue of the locking force of the locking assembly 30, so as to ensure that the stirring cylinder 11 is kept stable during stirring operation; in addition, power component 124 is installed on stirring support 125, makes each functional component integrated level high, and power component 124 is short to the power take off route of (mixing) shaft 122, does benefit to and improves drive power utilization efficiency, reduces material mixing device 10's whole volume, does benefit to miniaturized design.
Referring to fig. 1, in some embodiments, the locking assembly 30 includes a quick release hook 31 disposed on one of the stirring bracket 125 and the stirring barrel 11, and a quick release seat 32 disposed on the other of the stirring bracket 125 and the stirring barrel 11, and the quick release hook 31 is detachably fastened to the quick release seat 32. The locking structure of the quick-release clamping hook 31 and the quick-release clamping seat 32 is adopted, so that the stirring material barrel 11 is convenient and labor-saving to assemble and disassemble, and the stirring material barrel 11 is convenient to disassemble and clean regularly. Of course, in other embodiments, the lock joint assembly 30 may also adopt other lock structure assemblies in the prior art, such as an electromagnetic lock assembly, a spring lock assembly, etc.
Preferably, in the above embodiment, the locking assembly 30 is two and is arranged on two opposite sides of the mixing barrel 11 in a symmetrical structure, so as to further ensure that the mixing barrel 11 is stably installed.
Referring to fig. 3 to fig. 5, in some embodiments, the power assembly 124 includes a first mounting bracket 124a disposed on the stirring bracket 125, a driving member 124b disposed on the first mounting bracket 124a, a transmission assembly 124c drivingly connected to the driving member 124b, a second mounting bracket 124d disposed on the stirring bracket 125, and a supporting base 124e disposed on the second mounting bracket 124d, and the driving shaft 123 is rotatably disposed on the supporting base 124e and connected to the transmission assembly 124 c. Thus, the first mounting bracket 124a and the second mounting bracket 124d can integrate the driving member 124b, the transmission assembly 124c, the supporting seat 124e and the driving shaft 123 into the cartridge holder, so that the overall structure of the stirring executing mechanism 12 is more compact, the miniaturization design is facilitated, and the integration of the material stirring device 10 into the mobile chassis is facilitated. The rotary power output by the driving member 124b can be effectively transmitted to the driving shaft 123 through the transmission assembly 124c, and the driving shaft 123 can reliably rotate under the supporting and positioning of the supporting seat 124e, so as to drive the stirring shaft 122 and the stirring execution assembly 121 to rotate, thereby achieving the purpose of uniformly stirring the mixed materials to prepare the gap filler.

The cleaning actuator 22 further includes a spray head 222 disposed on the wall of the access hole 212a, and the spray head 222 is configured to spray the end effector. In the process of extending and withdrawing, the spray washing head 222 can spray high-pressure water beams to the outer wall of the tail end execution piece, the high-pressure water beams have strong impact force, and contaminated excessive gap filler can be washed and fall off from the outer wall surface, so that the cleaning purpose is achieved.
With continued reference to fig. 1 and 2, in some embodiments, the cleaning actuator 22 includes a cleaning element 221 disposed on the wall of the access hole 212a, and the cleaning element 221 is configured to scrub the end effector. During the process of extending and withdrawing, the washing piece 221 can simultaneously wipe the outer wall of the end executing piece to clean the contaminated excessive gap filler. Alternatively, the brush member 221 may be, but is not limited to, bristles, and preferably, the bristles are made of a material having superior hardness and elasticity, such as a hard plastic, a steel wire, or the like, so as to enhance the removal capability of the joint compound.
It will be appreciated that the spray head 222 and the scrubbing elements 221 cooperate to provide a composite cleaning action (i.e., a combination of bristle scrubbing and high pressure water jet flushing) on the end effector to facilitate effective and complete removal of any contaminated caulk from the outer wall.
Further, in some embodiments, the cleaning actuator 22 includes at least two of the cleaning members 221 and at least two of the spray heads 222, at least one of the cleaning members 221 and at least one of the spray heads 222 form a set of cleaning assemblies, and the cleaning assemblies are sequentially arranged along the hole depth direction of the access hole 212 a. Therefore, no matter the tail end executing part extends into the water tank body 211 from the inlet and the outlet or is pulled out of the water tank body 211, the tail end executing part can be subjected to one-time cleaning operation of each group of cleaning components at different height positions, so that more times of cleaning can be performed in a unit cleaning period, and the cleaning effect can be greatly improved.
Specifically, the cleaning assembly set in each floor height position comprises two cleaning parts 221 arranged oppositely at intervals and two spraying heads 222 arranged oppositely at intervals, the two cleaning parts 221 and the two spraying heads 222 are connected in a plane in an alternating end-to-end mode and form a rectangular distribution, and a rectangular cavity is formed to be longitudinally overlapped with the access hole 212a and used for the access of the end effector. Therefore, the outer peripheral surface of the tail end execution piece can be thoroughly cleaned, and the problem that cleaning quality is affected due to the fact that a cleaning vacuum area is formed is avoided.

Compared with a flowing water washing mode, the waste water amount and the water consumption amount of circulating water washing are greatly reduced, the economy is greatly improved, and the working condition characteristic that the caulking robot is far away from a water supply source for a long time is better met. However, after the cleaning water tank 21 works for a period of time, the circulating cleaning water will contain a lot of impurities of the gap filler, which easily causes the blockage of the spray head 222 and causes the abnormal work of the spray head 222. In view of the above, the filter 223 is installed at the water inlet end of the spray head 222, so that impurities in the gap filler can be filtered and removed before entering the spray head 222, thereby avoiding the above problems, increasing the recycling frequency of the cleaning water to a certain extent, saving resources, and improving the sustainable working capacity of the gap filling robot.
It is understood that the filter 223 may be any type or structure of filtering device in the prior art, such as but not limited to physical filtration (e.g. membrane filtration, screen filtration), chemical filtration, physical and chemical composite filtration, etc., and may be selected according to actual needs.
With continued reference to fig. 8, in some embodiments, the spray head 222 includes a filter element 222a, a pressurizing element 222b disposed on the filter element 222a, a connection joint 222c connected to the filter element 222a, a control valve 222d connected to the connection joint 222c, a switching joint 222e connected to the control valve 222d, a hose 222f connected to the switching joint 222e, a fixed block 222g connected to the hose 222f, and a spray head body 222h disposed on the fixed block 222g and connected to the hose 222f, wherein the spray head body 222h defines at least two spray holes 222i disposed side by side at intervals. The filter 222a is located downstream of the filter 223, and can perform secondary filtration of the cleaning water entering the head body 222h, thereby further filtering out impurities. The pressurizing member 222b is used for pressurizing the cleaning water entering the nozzle body 222h so as to form a high-pressure water beam, thereby ensuring the cleaning efficiency of the gap filler. The control valve 222d can control the water flow rate of the water which is started, stopped or ejected from the nozzle body 222h, so that the switching requirements of different working states are met, and the economical efficiency is improved. The fixing block 222g is used to fix the nozzle body 222h and other components to the inner wall of the tank body 211. In addition, because at least two spraying holes 222i which are arranged side by side at intervals are formed in the spray head body 222h, a multi-point synchronous output high-pressure water beam can be formed, and the multi-point gap filler on the outer wall of the tail end execution piece can be covered and flushed (namely, a larger area is flushed), so that the cleaning efficiency is higher and more thorough.
In order to avoid the splashing of the cleaning water to affect the environmental sanitation and waste of water resources due to the high pressure of the cleaning water beam sprayed to the end effector, in an embodiment, the cleaning actuator 22 further includes a water baffle 23, and the water baffle 23 is disposed on the tank cover 212 and shields one side of the access hole 212 a.
