[0039] The cleaning device provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0040] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the cleaning device includes: a base 10, a first cleaning mechanism 20, a second cleaning mechanism 30 and a transfer mechanism 40. The base 10 is provided with a mounting table 11, and the mounting table 11 is provided with a first station 111 and a second station 112; the first cleaning mechanism 20 is arranged at the first station 111, and is used for ultrasonic cleaning of the target object; the second cleaning mechanism 30 includes a rotating fixed component 31 and a flushing component 32, the rotating fixed component 31 is arranged at the second station 112, and is used for clamping and fixing the target object and driving the target object to rotate, and the flushing component 32 is used for flushing the target object in the rotating fixed component 31; the transfer mechanism 40 is connected to the base 10, and is used for carrying the target object to transfer between the first station 111 and the second station 112.

[0041] In the embodiment of the present application, a first station 111 and a second station 112 are provided on the mounting table 11 in the base 10, a first cleaning mechanism 20 is provided in the first station 111, and a second cleaning mechanism 30 is provided in the second station 112, and a transfer mechanism 40 can be used to carry and transfer the target object between the first station 111 and the second station 112. Then, the first cleaning mechanism 20 can be used to ultrasonically clean the target object in the first station 111, and the rotating fixing component 31 can be used to clamp and fix the target object in the second station 112 and drive the target object to rotate, so as to use the flushing component 32 to perform all-round flushing on the target object. In this way, the cooperation of the first cleaning mechanism 20 and the second cleaning mechanism 30 can realize step-by-step cleaning of the target object, thereby improving the cleaning effect, and the cleaning process can be flexibly set by matching the first cleaning mechanism 20 and the second cleaning mechanism 30 to meet different cleaning needs.

[0042] It is understandable that the cleaning device of the embodiment of the present application can be applied to the cleaning operation of the scraper 101 in the screen printing technology, that is, the target object is the scraper 101. Of course, it can also be applied to other cleaning processes and can be flexibly set according to actual needs, which is not limited in the present application.

[0043] Specifically, the base 10 can be set as a box structure, and a mounting platform 11 is provided in the box structure. Two workstations are provided on the mounting platform 11, namely a first workstation 111 and a second workstation 112. At the same time, a transfer mechanism 40 is provided in the box, and at least a part of the transfer mechanism 40 can be moved relative to the mounting platform 11, so that the target object can be transferred between the first workstation 111 and the second workstation 112 by using the transfer mechanism 40.

[0044] Furthermore, a first cleaning mechanism 20 for ultrasonic cleaning is provided in the first station 111, and a second cleaning mechanism 30 for flushing is provided in the second station 112, so that the first cleaning mechanism 20 and the second cleaning mechanism 30 can respectively perform different cleaning operations on the target object, thereby improving the cleaning effect on the target object.

[0045] It should be noted that when performing the cleaning operation of the target object, the cleaning order of the first cleaning mechanism 20 and the second cleaning mechanism 30 may not be limited, and the cleaning media used in the first cleaning mechanism 20 and the second cleaning mechanism 30 may also be flexibly selected and are not limited here.

[0046] In the embodiment of the present application, by setting two different cleaning mechanisms in the cleaning device, namely the first cleaning mechanism 20 and the second cleaning mechanism 30, the cleaning order of the two cleaning mechanisms and the type of cleaning medium used by each cleaning mechanism can be flexibly set during use. In this way, a variety of cleaning processes can be designed in combination to meet different cleaning needs, which can not only improve the cleaning effect but also improve the applicability of the cleaning device.

[0047] The second cleaning mechanism 30 includes a rotating fixed component 31 and a flushing component 32. The rotating fixed component 31 is installed in the second station 112. The flushing component 32 is arranged opposite to the rotating fixed component 31. The flushing component 32 can be directly or indirectly connected to the base 10. Furthermore, during the cleaning operation, the rotating fixed component 31 can be used to clamp and fix the target object, and can drive the target object to rotate, so that the flushing component 32 can be used to perform all-round flushing on the target object, thereby improving the cleaning effect of the target object.

[0048] It should be noted that the flushing component 32 can be connected to a cleaning medium supply system through a connecting pipe. For example, the flushing component 32 can be connected to a cleaning medium supply system such as a high-pressure water pump or a dry ice cleaning machine, so that pressurized cleaning medium can be introduced into the flushing component 32 through the cleaning medium supply system, and the cleaning medium is sprayed from the flushing component 32 to the surface of the target object, thereby achieving a flushing effect on the target object.

[0049] In some embodiments, the first cleaning mechanism 20 is an ultrasonic cleaning machine.

[0050] Specifically, the ultrasonic cleaning machine may include a tank body, an ultrasonic generator and an ultrasonic transducer, wherein the tank body is connected to the ultrasonic transducer, and the ultrasonic transducer is connected to the ultrasonic generator. A cleaning tank is provided in the tank body, and a cleaning medium may be contained in the cleaning tank. When cleaning, the target object is placed in the cleaning medium, and a high-frequency oscillation signal is emitted by the ultrasonic generator, and the high-frequency oscillation signal is converted into a high-frequency mechanical oscillation by the ultrasonic transducer, and then propagated to the cleaning medium, so as to realize ultrasonic cleaning of the target object.

[0051] In some embodiments, the cleaning medium used in the ultrasonic cleaning operation can be selected from: alcohol, cleaning agent, etc., wherein the cleaning agent can include a mixed solution of ester solvents and ketone solvents, for example, the cleaning agent can include a mixed solution of isophorone, acetone, butyl acetate, and xylene.

[0052] In other embodiments, the cleaning medium used in the flushing operation can be selected from: water, block dry ice or granular dry ice, etc. It should be noted that the cleaning medium used by the first cleaning mechanism 20 and the second cleaning mechanism 30 can be flexibly selected according to the actual application scenario, and the embodiments of the present application do not limit this.

[0053] Alternatively, if Figure 2 and Figure 3 As shown, the transfer mechanism 40 includes: a moving module 41, a connecting member 42 and a first clamping assembly 43; the moving module 41 is connected to the base 10, the connecting member 42 is connected to the moving module 41, the first clamping assembly 43 is installed on the connecting member 42, and the moving module 41 is used to drive the first clamping assembly 43 to move between the first station 111 and the second station 112, and transfer the target object through the first clamping assembly 43.

[0054] In the embodiment of the present application, the first clamping component 43 is installed on the movable module 41 through the connecting member 42, and the movable module 41 can drive the first clamping component 43 to move, and then the first clamping component 43 clamps the target object and transfers it between the first station 111 and the second station 112, so that different cleaning operations can be performed on the target object in the two stations respectively.

[0055] In some embodiments, the movable module 41 may include one or a combination of two or more of a linear movable module, a curved movable module, and a rotating module. The movable module 41 can not only drive the first clamping component 43 to move between the first station 111 and the second station 112, but also flexibly adjust the position of the first clamping component 43 to accurately clamp the target object.

[0056] Alternatively, if Figure 3 As shown, the first clamping assembly 43 includes: a first rotating driving member 431, a first clamping jaw driving member 432 and two first clamping jaws 433; the first rotating driving member 431 is installed on the connecting member 42, the first clamping jaw driving member 432 is connected to the first rotating driving member 431, and the two first clamping jaws 433 are respectively connected to the first clamping jaw driving member 432; the first rotating driving member 431 is used to drive the first clamping jaw driving member 432 to drive the two first clamping jaws 433 to rotate, and the first clamping jaw driving member 432 is used to drive the two first clamping jaws 433 to move relative to each other to clamp the target object.

[0057] In the embodiment of the present application, the first clamp driving member 432 can drive the two first clamps 433 to move relative to each other, so as to utilize the two first clamps 433 to clamp the target object. At the same time, the first rotating driving member 431 can drive the first clamp driving member 432 and the first clamp 433 to rotate, thereby realizing a multi-dimensional adjustment effect on the position of the first clamp 433.

[0058] In some embodiments, the first jaw driving member 432 can be a driving mechanism such as a jaw cylinder or a driving motor. The first jaw 433 is connected to the output end of the first jaw driving member 432, and the first jaw driving member 432 can drive the first jaw 433 to move back and forth.

[0059] Among them, a first jaw driving component 432 can be set corresponding to each first jaw 433 to achieve independent control of each first jaw 433; or two first jaws 433 can be installed in the same first jaw driving component 432, and the first jaw driving component 432 can be used to simultaneously control the movement of the two first jaws 433.

[0060] It should be noted that the first rotary drive member 431 may be a rotary drive mechanism such as a rotary cylinder or a rotary motor. The specific structure of the first rotary drive member 431 may be flexibly arranged according to actual needs, and the embodiment of the present application does not limit this.

[0061] Alternatively, if Figure 3 As shown, the flushing assembly 32 includes at least one nozzle 321, which is installed on the connecting member 42. The moving module 41 is also used to drive the nozzle 321 to move relative to the rotating fixed assembly 31 so as to flush the target object in the rotating fixed assembly 31 through the nozzle 321.

[0062] In the embodiment of the present application, the flushing assembly 32 includes at least one nozzle 321, and the nozzle 321 is installed on the connecting member 42, and then the movable module 41 can drive the nozzle 321 to move relative to the rotating fixed assembly 31, so as to realize the flushing operation of the target object in the rotating fixed assembly 31. In addition, by installing both the first clamping assembly 43 and the nozzle 321 on the movable module 41, the movable module 41 can realize the adjustment of the first clamping assembly 43 and the nozzle 321 respectively, which helps to improve the integration of the device.

[0063] In some embodiments, a flow channel is provided in the nozzle 321, and the flow channel has an inlet and an outlet. One end of the nozzle 321 with the inlet is used to connect with the cleaning medium supply system, and one end of the nozzle 321 with the outlet is used to spray the cleaning medium toward the target object in the rotating fixed assembly 31 to achieve a flushing operation on the target object.

[0064] Specifically, Figure 3 As shown, according to the different shapes of the nozzle 321 outlet, the nozzle 321 can be divided into a circular nozzle and a flat nozzle, wherein the outlet shape of the circular nozzle 321 is circular or elliptical, and the outlet shape of the flat nozzle 321 is rectangular or long strip, and the flow cross-sectional area of ​​the outlet of the flat nozzle 321 is larger than the flow cross-sectional area of ​​the outlet of the circular nozzle 321.

[0065] Furthermore, the flushing assembly 32 may include a circular nozzle 321 and a flat nozzle 321, both of which are mounted on the connector 42. When the second cleaning mechanism 30 is used to perform a cleaning operation on the target object, the flat nozzle 321 may be used to clean a large area of ​​the target object first. Since the outlet flow cross-sectional area of ​​the flat nozzle 321 is large, the cleaning area covered is large, which helps to improve the cleaning efficiency. Then, the circular nozzle 321 is used to clean a part of the target object. Since the outlet flow cross-sectional area of ​​the circular nozzle 321 is small, it is suitable for precise cleaning.

[0066] It should be noted that the nozzle 321 in the flushing component 32 may also adopt other structures, and those skilled in the art may flexibly select them according to actual needs, and the embodiments of the present application do not limit this.

[0067] Alternatively, if Figure 2 As shown, a rotating mechanism 411 is provided at one end of the movable module 41 close to the connecting member 42 , and the connecting member 42 is connected to the rotating mechanism 411 . The rotating mechanism 411 can drive the connecting member 42 to rotate to adjust the relative position of the first clamping assembly 43 and the nozzle 321 .

[0068] In the embodiment of the present application, a rotating mechanism 411 is provided at one end of the moving module 41 close to the connecting member 42, and the rotating mechanism 411 can drive the connecting member 42 to rotate, thereby switching the positions of the first clamping assembly 43 and the nozzle 321, so that when the target object needs to be transferred, the first clamping assembly 43 is rotated to the working position by the rotating mechanism 411, so that the target object can be clamped from the first station 111 or the second station 112 by the first clamping assembly 43. When the flushing operation needs to be performed, the nozzle 321 is rotated to the working position by the rotating mechanism 411, so that the nozzle 321 sprays the cleaning medium to the target object in the rotating fixed assembly 31.

[0069] Furthermore, the movable module 41 can be set as a robotic arm, which can realize multi-dimensional movement. Then, when performing the target object transfer operation, the robotic arm can be used to flexibly adjust the clamping position of the first clamping component 43, and when performing the flushing operation, the robotic arm can be used to flexibly adjust the flushing position of the nozzle 321 to achieve all-round cleaning of the target object.

[0070] It should be noted that the specific structure of the robotic arm can be found in the technical content of the relevant technology, and the embodiments of the present application will not be repeated here.

The second clamping assembly 313 is used to clamp and fix the target object, and the second clamping assembly 313 is driven to rotate by the second rotating driving member 312.

[0072] In the embodiment of the present application, a base plate 311 is set at the second workstation 112, a second rotating drive member 312 is installed on the base plate 311, and a second clamping assembly 313 is connected to the second rotating drive member 312. The second clamping assembly 313 can be used to clamp and fix the target object, so that during the flushing operation, the second rotating drive member 312 can be used to drive the second clamping assembly 313 to drive the target object to rotate, thereby achieving all-round flushing of the surface of the target object.

[0073] In some embodiments, the second rotary drive member 312 may be a rotary drive mechanism such as a rotary cylinder or a rotary motor. The specific structure of the second rotary drive member 312 may be flexibly set according to actual needs, and the embodiment of the present application does not limit this.

[0074] Alternatively, if Figure 4As shown, the second clamping assembly 313 includes a second jaw driving member 3131 and two second jaws 3132; the second jaw driving member 3131 is connected to the second rotating driving member 312, and the two second jaws 3132 are respectively connected to the second jaw driving member 3131, and the second jaw driving member 3131 is used to drive the two second jaws 3132 to move relative to each other so as to clamp and fix the target object.

[0075] In the embodiment of the present application, the two second jaws 3132 are respectively connected to the second jaw driving member 3131, and the two second jaws 3132 are arranged opposite to each other. The distance between the two second jaws 3132 can be adjusted by the second jaw driving member 3131 so that the second jaws 3132 can be used to clamp the target object.

[0076] In some embodiments, a support member 314 may be disposed between the two second clamping jaws 3132 , and a clamping space is formed by the two second clamping jaws 3132 and the support member 314 . When the target object is placed in the clamping space, the support member 314 may support the target object.

[0077] Exemplarily, when the cleaning device is used to clean the scraper 101, a slot can be set on the upper end surface of the support member 314, and the structure of the slot can match the blade structure of the scraper 101, so that when the scraper 101 is clamped with the blade facing downward between the two second clamping jaws 3132, the blade of the scraper 101 is clamped in the slot, thereby protecting the blade of the scraper 101.

[0078] In some embodiments, the second jaw driving member 3131 can be a driving mechanism such as a jaw cylinder or a driving motor. A second jaw driving member 3131 can be provided for each second jaw 3132 to achieve separate control of each second jaw 3132; or two second jaws 3132 can be installed in the same second jaw driving member 3131, and the second jaw driving member 3131 can be used to simultaneously control the movement of the two second jaws 3132.

[0079] Alternatively, if Figure 1 and Figure 6 As shown, the cleaning device further includes a collecting mechanism 51, which is disposed on a side of the mounting platform 11 away from the rotating fixing assembly 31. The collecting mechanism 51 is provided with a receiving cavity 511 for collecting the cleaning medium. The mounting platform 11 at the second station 112 is provided with a plurality of through holes 113 (such as Figure 2 As shown), the through hole 113 is connected to the accommodating cavity 511.

[0080] In the embodiment of the present application, a collecting mechanism 51 is arranged below the rotating fixing assembly 31 in the second station 112, and a plurality of through holes 113 are provided in the corresponding mounting platform 11, so that the through holes 113 are connected to the accommodating cavity 511 in the collecting mechanism 51, and then when the second cleaning mechanism 30 is used to perform a cleaning operation, the collecting mechanism 51 can be used to collect the cleaning medium scattered during the cleaning process.

[0081] The collecting mechanism 51 is detachably mounted on a side of the mounting platform 11 away from the rotating fixing assembly 31, thereby facilitating the disassembly and installation of the collecting mechanism 51 and facilitating the cleaning and maintenance of the collecting mechanism 51. The detachable connection between the collecting mechanism 51 and the mounting platform 11 includes, but is not limited to, bolt connection, clamping, plug-in connection, etc.

[0082] Alternatively, if Figure 1 and Figure 2 As shown, a shielding plate 12 is also provided in the base 10, and the shielding plate 12 is arranged around the second station 112. By arranging the shielding plate 12 around the second station 112, the cleaning medium sprayed by the flushing component 32 is shielded to prevent the cleaning medium from splashing to the area outside the second station 112 and contaminating other components.

[0083] Alternatively, if Figure 1 and Figure 5 As shown, the cleaning device further includes a fixing frame 52 and a material storage tray 53.
