[0003] Existing cleaning equipment can achieve batch cleaning in an assembly line style. However, for the cleaning of raw materials in the same batch or across batches, since their sources, storage conditions, and previous processes may be different, it is difficult to carry out targeted cleaning for raw materials with different dirtiness. Conventional means use the same cleaning parameters for continuous processing, which cannot achieve a balance between cleaning quality and cleaning efficiency, resulting in a decline in productivity. Summary of the invention

[0004] Based on this, an object of the present invention is to provide a system and method for cleaning a display module.

[0005] The invention provides the following technical solutions: a cleaning system for a display module, comprising an input component, a transfer component and an ultrasonic cleaning component; wherein the input component is used to transport the display module to the transfer component, the transfer component is used to transfer the display module to the ultrasonic cleaning component, and the ultrasonic cleaning component is used to perform ultrasonic cleaning on the display module;

[0008] Furthermore, the input component also includes a third spray hole arranged on the first bottom plate, the third spray hole is located on the lower side of the crawler track, and the third spray hole is used to spray the lower side of the crawler track.

[0009] Furthermore, the transfer assembly also includes a support frame, a first motor is arranged on the support frame, the connecting frame is rotatably connected to the support frame, and the output shaft of the first motor is fixedly connected to the connecting frame.

[0010] Furthermore, the ultrasonic cleaning component includes an ultrasonic cleaning machine for ultrasonically cleaning the display module, and a transmission module provided on the ultrasonic cleaning machine for transmitting the display module in the ultrasonic cleaning machine out.

[0011] Furthermore, the cleaning system also includes a second spray component and an output component. The transmission module transfers the display module to the output component, the output component transports the display module out, and the second spray component sprays the display module of the output component.

[0012] Furthermore, the transmission module includes a first transmission unit, a second transmission unit, a third transmission unit, a fourth transmission unit and a pushing unit arranged on the ultrasonic cleaning machine, and a pushing unit for pushing the display module onto the output component, and a control unit for controlling the operation of the first transmission unit, the second transmission unit, the third transmission unit, the fourth transmission unit, the pushing unit and the pushing unit; the first transmission unit, the second transmission unit and the third transmission unit are arranged in a horizontal arrangement, and the fourth transmission unit is located at the lower side of the first transmission unit, the second transmission unit and the third transmission unit, and is arranged perpendicular to the first transmission unit, the second transmission unit and the third transmission unit.

[0014] Furthermore, the pushing unit includes a driving member arranged in the ultrasonic cleaning machine, and a push plate arranged on the output shaft of the driving member. When the fourth transmission unit transmits the display module to the upper side of the push plate, the output shaft of the driving member is extended so that the push plate lifts the display module, and then the display module is transmitted upward through the cooperation of the second transmission unit and the third transmission unit.

[0015] On the other hand, a method for cleaning a display module is provided, which is applied to the above-mentioned cleaning system, and the cleaning method comprises the following steps:

DETAILED DESCRIPTION

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] The present invention provides a first embodiment, which provides a cleaning system for a display module 7, such as Figure 1 , Figure 4 and Figure 8As shown, it includes an input component 1, a transfer component 5 and an ultrasonic cleaning component 6; wherein the input component 1 is used to transport the display module 7 to the transfer component 5, the transfer component 5 is used to transfer the display module 7 to the ultrasonic cleaning component 6, and the ultrasonic cleaning component 6 is used to perform ultrasonic cleaning on the display module 7;

[0034] The transfer component 5 includes a connecting frame 53, two rolling wheels respectively arranged at both ends of the connecting frame 53, and a track 52 connected between the two rolling wheels, at least one of the rolling wheels is a self-driving rotating driving wheel 51, and the track 52 is arranged in an inclined state with respect to the ultrasonic cleaning component 6.

[0035] Among them, the surface of the crawler 52 is relatively smooth and has a fixed friction coefficient. The display module 7 itself has a certain degree of smoothness. When the display module 7 is completely clean, on the crawler 52 adjusted to a fixed tilt angle, the time when the display module 7 slides down is within a standard time segment value. If there are stains such as dust and oil film on the display module 7, it will affect its cleanliness. Then, the time for the crawler 52 to slide up and down when the crawler 52 is adjusted to a fixed tilt angle is within a non-standard time segment value. At this time, the system controls and adjusts the cleaning intensity of the ultrasonic cleaning component 6 to be higher than that of the standard state. Due to the continuous processing of batches of display modules 7, some dirt remains on the surface of the crawler 52, which pollutes the surface on the one hand, and on the other hand, it will also affect the judgment of the cleanliness of the display module 7 using the sliding time. Therefore, the operator of the crawler 52 can start the driving wheel 51 to achieve the replacement of the crawler 52.

[0036] Specifically, the display module 7 is transmitted to the transfer component 5 through the transmission of the input component 1. The highest point of the crawler 52 of the transfer component 5 is parallel to the highest point of the input component 1, so that the input component 1 can input the display module 7 to the transfer component 5, and the crawler 52 of the transfer component 5 is tilted downward to the ultrasonic cleaning component 6 whose height is lower than that of the crawler 52. Therefore, when the display module 7 is transmitted to the crawler 52 of the transfer component 5, due to the tilted state of the crawler 52, the display module 7 will slide down in the direction of the ultrasonic cleaning component 6 by its own gravity. At this time, the data collection module will collect the time consumed by the display module 7 to slide down. The data collection module can be arranged on the upper side of the transport component 5 and fixed on the fixed body. The data collection module is a prior art and will not be described in detail here. The data collection module controls the ultrasonic cleaning component 6 to adjust the parameters according to the time when the display module 7 slides down. That is to say, the longer the time when the display module 7 slides down, the dirtier the surface of the display module 7 is. On the contrary, the shorter the time when the display module 7 slides down, the cleaner the surface of the display module 7 is. The cleaning intensity of the ultrasonic cleaning component 6 is adjusted accordingly. When the working surface of the crawler 52 contacts the display module 7 for a long time, the working surface of the crawler 52 will be contaminated. At this time, the operator can rotate the driving wheel 51. In this embodiment, one of them is the self-driving driving wheel 51, and the other is the driven wheel 55. The driving wheel 51 includes a main body and a driving motor. The driving motor is fixedly connected to the connecting frame 53. The output shaft of the driving motor is fixedly connected to the main body. By starting the driving motor to control the rotation of the main body, the crawler 52 is rolled, and the working surface of the crawler 52 is switched; that is to say: the side of the crawler 52 used to carry the display module 7 is the working surface, and the opposite surface is the standby surface. The crawler 52 can be moved by the driving wheel 51 and The rolling drive of the driven wheel 55 switches the position of the covering belt surface thereon, for example, the covering belt in the initial state is divided into a first layer close to the upper layer and a second layer close to the lower layer. In the initial case, the first layer is located at the working surface position, or the first layer is used as the working surface and the second layer is used as the standby surface. In another case, the driving wheel 51 and the driven wheel 55 are driven so that the second layer is used as the working surface and the first layer is used as the standby surface. Therefore, the driving wheel and the driven wheel 55 can be driven in a controllable manner so that the first layer and the second layer of the covering belt are alternately used as the working surface or the standby surface.

[0037] like Figure 2As shown, the cleaning system also includes a first spray component 2, which is located above the input component 1 and is used to spray the display module 7 on the input component 1; the input component 1 includes a first base plate 11, a plurality of first spray holes 12 and a plurality of first rollers 13 are arranged on the first base plate 11, and the display module 7 is transported to the track 52 on the transfer component 5 by the rotation of the first rollers 13, and the lower side of the display module 7 is cleaned through the first spray holes 12.

[0038] Among them, the first spray component 2 includes multiple spray heads, which are connected in series through water pipes, and the water pipes are connected to a water pump. The water pump pumps an external water source into the water pipe and sprays it out from the spray head, thereby cleaning the display module 7 on the input component 1; the multiple first rollers 13 of the input component 1 can be self-driven first rollers 13, that is, they can be provided with electrical components, such as motors, so as to drive themselves to rotate, or multiple first rollers 13 are connected to each other through belts and pulleys, and all the first rollers 13 are driven to rotate by a motor, and the first rollers 13 are rotated in the direction of the transfer component 5, so that the display module 7 is transmitted to the transfer component 5, and the first spray holes 12 are also connected in series through water pipes, which are similar to the structure of the first spray component 2 and will not be elaborated here; the lower surface of the display module 7 can be sprayed through the first spray holes 12.

[0039] like Figure 2 and Figure 4 As shown, the input assembly 1 further includes a third spray hole 8 provided on the first bottom plate 11 , and the third spray hole 8 is located at the lower side of the crawler 52 , and the third spray hole 8 is used to spray the lower side of the crawler 52 .

[0040] Among them, the third spray hole 8 can be set separately, that is, the third spray hole 8 is connected to a water pipe separately, and a water pump is set on the water pipe. The water pump pumps external water into the water pipe and sprays from the third spray hole 8. The third spray hole 8 can also be connected to the water pipe on the first spray hole 12. When the first spray hole 12 sprays the display module 7, the third spray hole 8 also sprays the lower surface of the crawler 52; specifically, when the upper surface of the crawler 52, that is, the working surface, is in contact with the display module 7 for a long time, resulting in dirtiness, the upper surface and the lower surface of the crawler 52 are switched through the cooperation of the driving wheel 51 and the driven wheel 55, and then the lower surface of the crawler 52 is cleaned through the third spray hole 8, thereby ensuring that the working surface of the crawler 52 is always in a clean state.

[0041] like Figure 4 and Figure 8As shown, the transfer assembly 5 also includes a support frame 56 , a first motor 54 is arranged on the support frame 56 , the connecting frame 53 is rotatably connected to the support frame 56 , and the output shaft of the first motor 54 is fixedly connected to the connecting frame 53 .

[0042] Among them, the support frame 56 is used to support the connecting frame 53, and the support frame 56 is arranged next to the input component 1. The support frame 56 includes an extension support rod and a limit rod. The extension support rod is connected to the first bottom plate 11 of the input component 1. The extension support rod is a frame structure, which is welded by multiple horizontal tubes and vertical tubes. The limit rod is arranged at the end of the extension support rod away from the first platform. The limit rod is a horizontal rod, and its extension direction is perpendicular to the length direction of the first platform; it can be understood that the axis of the output shaft of the first motor 54 is the same as the axis of the driving wheel 51. The first motor 54 can drive the connecting frame 53 to swing, so that the connecting frame 53 drives the driving wheel 51 and the driven wheel 55 to swing, thereby adjusting the inclination angle of the track 52. Therefore, according to the specific working scene, the inclination angle of the track 52 is adjusted to adjust the time for the display module 7 to slide down. The variable inclination angle range of the track 52 is 0° to 60°.

[0043] like Figure 3 , Figure 5 and Figure 6 As shown, the ultrasonic cleaning component 6 includes an ultrasonic cleaning machine 611 for ultrasonically cleaning the display module 7, and a transmission module arranged on the ultrasonic cleaning machine 611 for transmitting the display module 7 in the ultrasonic cleaning machine 611 out; the cleaning system also includes a second spray component 4 and an output component 3, the transmission module transmits the display module 7 to the output component 3, the output component 3 transports the display module 7 out, and the second spray component 4 sprays the display module 7 of the output component 3.

[0044] The output assembly includes a second bottom plate 31, a plurality of second rollers 32 and a second spray hole 33 arranged on the second bottom plate 31;

[0045] It can be understood that the display module 7 enters the ultrasonic cleaning machine 611 for cleaning. After cleaning, it is transported to the output component 3 through the transmission module. The specific structure of the output component 3 is similar to that of the input component 1, which will not be elaborated here. The second spray component 4 is similar to the structure of the first spray component 2, which will not be elaborated here. The display module 7 is transported out through the output component 3 and the lower surface of the display module 7 is sprayed. In the process of transporting, the upper surface of the display module 7 is sprayed through the second spray component 4.

[0046] like Figure 5-Figure 7As shown, the transmission module includes a first transmission unit 61, a second transmission unit 62, a third transmission unit 63, a fourth transmission unit 64 and a pushing unit arranged on the ultrasonic cleaning machine 611, and a pushing unit for pushing the display module 7 onto the output component 3, and a control unit for controlling the operation of the first transmission unit 61, the second transmission unit 62, the third transmission unit 63, the fourth transmission unit 64, the pushing unit and the pushing unit; the first transmission unit 61, the second transmission unit 62 and the third transmission unit 63 are arranged in a horizontal arrangement, and the fourth transmission unit 64 is located at the lower side of the first transmission unit 61, the second transmission unit 62 and the third transmission unit 63, and is arranged perpendicular to the first transmission unit 61, the second transmission unit 62 and the third transmission unit 63.

[0047] The first transmission unit 61, the second transmission unit 62, the third transmission unit 63, and the fourth transmission unit 64 all include two rotating shafts 6101 rotatably connected to the ultrasonic cleaning machine 611, a plurality of transmission modules arranged between the two rotating shafts 6101, and a second motor 6105 arranged on the ultrasonic cleaning machine 611, wherein the output shaft of the second motor 6105 is fixedly connected to one of the rotating shafts 6101; the transmission module includes two transmission wheels 6102 respectively arranged on the two rotating shafts 6101, a transmission belt 6103 connected between the two transmission wheels 6102, and a plurality of clips 6104 evenly spaced on the transmission belt 6103;

[0048] The pushing unit includes a driving member arranged in the ultrasonic cleaning machine 611, and the driving member can be an electric push rod 65, a cylinder, an oil cylinder, etc.; and a push plate 66 arranged on the output shaft of the driving member. When the fourth transmission unit 64 transmits the display module 7 to the upper side of the push plate 66, the output shaft of the driving member is extended so that the push plate 66 lifts the display module 7, and then the display module 7 is transmitted upward through the cooperation of the second transmission unit 62 and the third transmission unit 63;

[0049] The pushing unit is arranged on the upper right side of the ultrasonic cleaning machine 611, and the pushing unit comprises a supporting frame, the supporting frame is fixedly connected to the fixed body, a third motor 68 is fixedly connected to the supporting frame, a pushing plate 610 is slidably connected to the supporting frame, and a screw 69 is fixedly connected to the output shaft of the third motor 68, and the screw 69 is threadedly connected to the pushing plate 610; the supporting frame is used to support the motor and the pushing plate 610;

[0050] The control unit includes a first sensor 6106, a second sensor 6107, a third sensor 6108, a fourth sensor 6109 and a fifth sensor 6110 and a controller, and the five sensors may be infrared sensors, distance sensors, position sensors, optical sensors, etc.;

[0051] It can be understood that when the display module 7 slides off the crawler 52, it will first slide between the first transmission unit 61 and the second transmission unit 62, and be held by the clips 6104 on the first transmission unit 61 and the second transmission unit 62. At this time, the first sensor 6106 senses the display module 7 and sends a signal to the controller. The controller controls the first transmission unit 61 and the second transmission unit 62 to start the second motors 6105 at the same time. The output shaft of the second motor 6105 of the first transmission unit 61 rotates forward, and the output shaft of the second motor 6105 of the second transmission unit 62 rotates reversely. The rotation of the output shaft of the second motor 6105 drives the rotating shaft 6101 to rotate, and the rotating shaft 6101 rotates. The rotation of shaft 6101 drives the conveyor belt 6103 to move, thereby moving the clip 6104 of the conveyor belt 6103, and then the clip 6104 moves the display module 7 thereon to move downward. When the clip 6104 moves to the lowest limit position, it rotates and no longer supports the display module 7. The display module 7 falls downward by its own gravity. At this time, the second sensor 6107 senses the display module 7, controls the first conveyor unit 61 and the second conveyor unit 62 to stop operating, and controls the fourth conveyor unit 64 to operate. The second motor 6105 of the fourth conveyor unit 64 starts to rotate its output shaft in the positive direction, thereby causing the conveyor belt 6103 to move. The display module 7 moves to the right side, and the clamp 6104 on the second transmission unit 62 pushes the display module 7 to move to the right side. When the display module 7 moves to the right side and is sensed by the fifth sensor 6110, the fifth sensor 6110 controls the fourth transmission unit 64 to stop operating and starts the electric push rod 65. The output shaft of the electric push rod 65 extends to push the display module 7 to move upward. When the display module 7 moves upward and is sensed by the fourth sensor 6109, the second motor 6105 of the second transmission unit 62 rotates in the reverse direction, and the second motor 6105 of the third transmission unit 63 rotates forward, so that the clamps 6104 on the second transmission unit 62 and the third transmission unit 63 support the display module 7. The display module 7 moves upward. When the display module 7 is sensed by the third sensor 6108, the third sensor 6108 will control the second transmission unit 62 and the third transmission unit 63 to stop operating, and control the output shaft of the electric push rod 65 to retract, and also control the third motor 68 to start. The output shaft of the third motor 68 will drive the screw 69 to rotate, and the screw 69 will push the push plate 610 to move. After the push plate 610 pushes the display module 7 to the output component 3, the output shaft of the third motor 68 will reverse, so that the push plate 610 will reset and stop operating, thereby transporting the display module 7 in the ultrasonic cleaning machine 611 to the output component 3 through the transmission module.

[0052] The present invention provides a second embodiment, which discloses: a method for cleaning a display module 7, which is applied in the above-mentioned cleaning system, and the cleaning method comprises the following steps:

[0053] Step S1: In the initial state, the ultrasonic cleaning component 6 is controlled to operate with standard cleaning parameters;

[0054] Step S2: when the transfer component 5 transports the display module 7 into the ultrasonic cleaning component 6, collecting the current sliding time of the display module 7;

[0055] Step S3: calculating the dirtiness value of the display module 7 entering the ultrasonic cleaning component 6 based on the sliding time;

[0056] Step S4: controlling the cleaning parameters of the ultrasonic cleaning component 6 according to the dirtiness value.

[0057] It can be understood that in the mode of batch ultrasonic cleaning, "namely, each time a rated number of display modules 7 are fed into the ultrasonic cleaning component 6, ultrasonic cleaning is then performed uniformly";

[0058] Step S4 specifically includes the following steps:

[0059] Step S4A1: based on the rated number of display modules 7 fed into the ultrasonic cleaning assembly 6, calculating the dirtiness value of each display module 7, and determining the cleaning parameters of the ultrasonic cleaning assembly 6 of the current batch according to the average value of the dirtiness value of each display module 7;

[0060] Step S4A2: Update the control of the ultrasonic cleaning component 6 based on the determined cleaning parameters and start cleaning.

[0061] The cleaning parameter control of the ultrasonic cleaning component 6 may include: the frequency of the ultrasonic generator, the number of ultrasonic generators, etc.;

[0062] The dirtiness value can be divided into three levels, where level one is the standard value, level two is relatively dirty, and level three is very dirty. The cleaning parameters of the ultrasonic cleaning component 6 correspond to the levels of the dirtiness value.

[0063] The present invention provides a third embodiment, which provides a method for cleaning a display module 7. The steps of this embodiment are the same as those of the second embodiment except step S4. The difference is that:

[0064] Step S4: controlling the cleaning parameters of the ultrasonic cleaning component 6 according to the dirtiness value, specifically comprising:

[0065] In the mode of continuous ultrasonic cleaning, "the ultrasonic cleaning component 6 is always open, and the display module 7 to be cleaned is continuously fed thereinto and the display module 7 that has been cleaned is removed therefrom";

[0066] Step S4B1: When the dirt values of the front display module 7 are all at level one and a level-two dirt value is detected for the first time, put the display module 7 with this level-two dirt value in, without changing the current ultrasonic cleaning control parameters, and continue to detect the subsequent display modules 7. If the number of display modules 7 with level-two dirt is detected to exceed n1 within the number interval below c1, switch the ultrasonic cleaning control parameters up one level. If level-two dirt is detected within the number interval above c1, do not perform the switch and continue to use the current ultrasonic cleaning control parameters, and at the same time reset this discrimination program with this newly detected level-two dirt value;

[0067] c1 is the "rounded down" value of 1 / 2d. For example, when d is 6, c1 is 2, and n1 can be preset according to the situation. For example, n1 = 2, 3, 4, etc.;

[0068] c2 < c1, and n2 can be preset according to the situation. Preferably, n2 = 3.

[0069] In summary, by tilting the track 52 to slide the display module 7 into the ultrasonic cleaning component 6, at the same time, it is possible to measure the dirt degree of the display module 7 by using the parameters collected during the downward slide (such as the downward slide time), so as to realize the real-time control of the cleaning parameters. Without the need for an additional complex acquisition and analysis device to calculate the dirt degree of the display module 7, efficient and high-quality cleaning can be achieved; in addition, the design of the cleaning method also greatly saves the cleaning operation time, enabling the most suitable cleaning response method for different dirt detection situations of the display module 7, and avoiding the problems of increased processing time and increased useless consumption caused by blindly strengthening the cleaning program level.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0071] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the patent of the present invention.
