[0171] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and material examples provided by the present application, but those of ordinary skill in the art can appreciate the application of other processes and / or the use of other materials.

[0172] Workpieces usually need to be cleaned of impurities on the surface during the production process or after production is completed. For example, the cleaning requirements for electronic products are higher, and the cleanliness of some components of electronic products often has a great impact on their use. For example, the surface cleanliness of the lens of electronic products often affects the clarity of the images or videos obtained by the camera of electronic products. In the production process of electronic products, the cleaning of the lens is very important to ensure the final camera effect of the electronic products.

[0173] See also Figure 1 , the following is a detailed description of the present application using the cleaning of the lens 11 of the component 10 that may be involved in the production process of electronic products as an example. In some cases, the lens 11 of the component 10 may be three, and in other cases, the number of the lens 11 may be more or less. In some cases, please refer to Figure 2 (A) After the lens 11 is installed in the component 10, there is a recessed structure 12. The recessed structure 12 may make the cleaning effect unsatisfactory. Cleaning the lens 11 with the recessed structure 12 is more complicated and difficult. Ordinary wiping methods cannot clean the lens 11 well. Please refer to Figure 2 (B) In some cases, the recessed structure 12 is disposed on two opposite sides of the lens 11 , that is, both the upper and lower sides of the lens 11 have the recessed structure 12 .

[0174] See also Figure 3As an exemplary description, an embodiment of the present application provides a cleaning device 20 for the lens 11 of the component 10, which can clean the lens 11, and specifically includes a first blowing device 21, a first wiping device 22, a second wiping device 23 and a second blowing device 24. The first blowing device 21 can use airflow to perform a first blowing treatment on the lens to complete the first cleaning. The first cleaning can clean off larger impurities or impurities with less adhesion on the lens, thereby avoiding scratches on the lens and the wiping cloth caused by these impurities during the subsequent wiping process; the first wiping device 22 can perform a first wiping treatment on the lens to complete the second cleaning. The second cleaning can use wiping to remove smaller impurities and some impurities adhering to the lens surface; the second wiping device 23 can perform a second wiping treatment on the lens 11 to complete the third cleaning. The third cleaning can use wiping to remove smaller impurities and some impurities with greater adhesion adhering to the lens surface and new impurities that may be generated by the first wiping treatment; the second blowing device 14 can use airflow to perform a second blowing treatment on the lens 11 to complete the fourth cleaning. The fourth cleaning can further remove new impurities that may be generated by the second wiping treatment. The impurities may have been firmly adhered to the lens surface, but have been detached and still remain on the lens surface after the first wiping treatment and the second wiping treatment. The four cleanings can better remove impurities on the surface of the lens 11 and achieve a higher degree of cleanliness. The cleaning effect of the lens with a recessed structure is also better. The cleaning of the lens with a recessed structure is more difficult than that of the lens with a planar structure. The recessed part can hide impurities, so the cleaning of the lens with a recessed structure often cannot completely clean the edge of the recessed part. However, the four cleanings of the present application can effectively remove impurities on the surface of the lens with a recessed structure.

[0175] See also Figure 4Another embodiment of the present application provides a cleaning device 30, including a first blowing device 31, a first wiping device 32, a second wiping device 33, a second blowing device 34 and a turntable 36. The turntable 36 enables the workpiece to be transferred between the first blowing device 31, the first wiping device 32, the second wiping device 33, and the second blowing device 34 to perform corresponding cleaning processes, wherein the first cleaning can clean up larger impurities or impurities with less adhesion on the lens 11, thereby preventing these impurities from scratching the lens 11 and the wiping cloth during the subsequent wiping process; the first wiping device 32 can perform a first wiping process on the lens to complete the second cleaning, and the second The first cleaning can utilize wiping to remove smaller impurities and some impurities adhering to the lens surface; the second wiping device 33 can perform a second wiping treatment on the lens 11 to complete a third cleaning, and the third cleaning can utilize wiping to remove even smaller impurities and some impurities with greater adhesion adhering to the lens surface and new impurities that may be generated by the first wiping treatment; the second blowing device 34 can use airflow to perform a second blowing treatment on the lens 11 to complete a fourth cleaning, and the fourth cleaning can further remove new impurities that may be generated by the second wiping treatment, which may have been originally firmly adhered to the lens surface, but have been detached and still remain on the lens surface after the first wiping treatment and the second wiping treatment.

[0176] In the following discussion, the cleaning device 30 is taken as an example for further explanation.

[0177] Please continue to see Figure 4 In one embodiment, the first blowing device 31 includes a plurality of air pipes 313. The plurality of air pipes 313 can be operated to change their own shapes, and provide different air flow directions to meet the blowing directions required during the cleaning process by changing their own shapes.

[0178] In one embodiment, the first blowing device 31 and the second blowing device 34 can be the same devices or different devices. The first blowing device 31 and the second blowing device 34 can change the shape of their air pipes 313 as needed to provide the required blowing direction.

[0179] In one embodiment, the first air blowing device 31 and the second air blowing device 34 both include an air supply member 311 and an air control member 312. The air supply member 311 is used to store gas, and the air control member 312 is connected to one end of the air supply member 311. The first air blowing device 31 also includes a fifth channel 3121, which is connected to the air supply member 311 through the air control member 312. The gas enters the air pipe 313 from the air supply member 311 through the air control member 312 and the fifth channel 3121 in sequence, and the air control member 312 is used to adjust the amount of gas passing through the fifth channel 3121.

[0180] Please also see Figure 5 and Figure 6 In one embodiment, the first wiping device 32 includes a frame 325, a carrier 329, a feeding mechanism 323 and a receiving mechanism 324, a first wiping head 321 and a driving mechanism 326, wherein the carrier 329, the feeding mechanism 323 and the receiving mechanism 324, the first wiping head 321 and the driving mechanism 326 are all arranged on the frame 325, the carrier 329 is used to place the workpiece to be wiped, the feeding mechanism 323 is used to provide a clean and unused wiping cloth 322 to the top of the workpiece on the carrier 329, the first wiping head 321 is driven by the driving mechanism 326 to press the wiping cloth 322 to the workpiece on the carrier 329 and wipe the lens 11 to remove impurities on the lens 11, and the receiving mechanism 324 recycles the used wiping cloth 322. It should be noted that in order to facilitate the display of the positional relationship between the various components, the workpiece is replaced by the component 10 for illustration.

[0181] In some embodiments, the feeding mechanism 323 includes a feeding wheel 3231, a first supporting wheel 3232, and a second supporting wheel 3233. The feeding wheel 3231, the first supporting wheel 3232, and the second supporting wheel 3233 are rotatably arranged on the frame 325, and the feeding wheel 3231, the first supporting wheel 3232, and the second supporting wheel 3233 are all arranged on the upper side of the wiping surface when the first wiping head 321 wipes the workpiece, and the first supporting wheel 3232 and the second supporting wheel 3233 can support the wiping cloth 322 provided by the feeding wheel. In one embodiment, only one supporting wheel can be used to support the wiping cloth 322, for example, only the first supporting wheel 3232 is used to support the wiping cloth 322. The receiving mechanism 324 includes a receiving wheel 3241 and a third supporting wheel 3242, which are rotatably arranged on the frame 325, and are both arranged on the lower side of the wiping surface when the first wiping head 321 wipes the lens. The wiping cloth 322 is drawn out from the feeding wheel 3231, and is wound around the first supporting wheel 3232, the second supporting wheel 3233 and the third supporting wheel 3242 in sequence, and then is wound around the receiving wheel 3241, and the wiping cloth 322 between the second supporting wheel 3233 and the third supporting wheel 3242 is located between the carrier 329 and the first wiping head 321. When wiping the lens, the first wiping head 321 is driven by the driving mechanism 326 to press the wiping cloth 322 to the surface of the lens 11 to perform a trajectory movement. In some embodiments, the first wiping head 321 moves along a preset trajectory after pressing the wiping cloth 322 to the surface of the lens 11, that is, the first wiping head 321 is driven by the driving mechanism 326 to move along a preset trajectory to drive the wiping cloth 322 to better clean the lens. By arranging the receiving wheel 3241 and the third supporting wheel 3242 on the lower side of the wiping surface when the first wiping head 321 wipes the lens, it can be effectively prevented that when the first wiping head 321 wipes the lens, impurities on the receiving wheel 3241 and the used wiping cloth fall onto the lens or the first wiping head 321, thereby affecting the wiping effect of the operation of wiping the lens.

[0182] In the present application, the supporting wheel is arranged in combination with the feeding wheel 3231 and the receiving wheel 3241, which can make the wiping cloth 322 move more smoothly on the one hand, and can make the wiping cloth 322 be more effectively supported to cooperate with the movement of the wiping head on the other hand. Specifically, the wiping cloth 322 between the second supporting wheel 3233 and the third supporting wheel 3242 does not need to be tensioned, and the wiping cloth 322 between the second supporting wheel 3233 and the third supporting wheel 3242 has a certain relaxation state, so that the wiping cloth and the lens can be slightly moved when the first wiping head 321 wipes the lens. The micro-movement is that after the first wiping head 321 presses the wiping cloth 322 to the lens and moves, a small distance of relative movement is generated between the wiping cloth 322 and the lens, so that the wiping cloth can remove impurities on the surface of the lens.

[0183] See also Figure 7 In one embodiment, the driving mechanism 326 includes a first driving member 3261 and a second driving member 3264, and the first driving member 3261 is disposed on the second driving member 3264. The first driving member 3261 can drive the first wiping head 321 to press against the wiping cloth 322, and the second driving member 3264 can drive the first wiping head 321 to move along a preset trajectory. In one embodiment, the first driving member 3261 includes a support frame 3262 and an adjuster 3263, and the first wiping head 321 is disposed on the support frame 3262, and the support frame 3262 is disposed on the adjuster 3263, and the adjuster 3263 can drive the support frame 3262 to move so as to drive the first wiping head 321 to move up and down, so as to adjust the height of the first wiping head 321 relative to the height of the lens 11. In one embodiment, the adjuster 3263 can be a lifting cylinder.

[0198] In one embodiment, the second wiping device 33 and the first wiping device 32 have the same structure and also use cleaning liquid for wiping, but there is a difference that the cleaning liquid of the second wiping device 33 and the cleaning liquid of the first wiping device 32 can be different, that is, another cleaning liquid is introduced into the wiping head of the second wiping device 33 for wiping. By wiping with different cleaning liquids by the first wiping device 32 and the second wiping device 33, different impurities can be cleaned, and the effect is better.

[0199] In one embodiment, the second wiping device 33 and the first wiping device 32 basically have the same structure, wherein only the liquid supply device 35 is missing, and the wiping head of the second wiping device 33 does not need to have a channel to introduce the cleaning liquid. Under this structure, the second wiping device 33 can provide dry wiping, which can clean the cleaning liquid remaining on the lens after wiping by the first wiping device 32, thereby avoiding the influence of the cleaning liquid of the first wiping device 32 on the lens.

[0200] See also Fig.12 The present application also provides a workpiece cleaning method, which can be implemented in the above-mentioned cleaning device, comprising the following steps:

[0201] S10, performing a first air blowing process on the lens;

[0202] The first cleaning process is completed by blowing air directly onto the lens, with the aim of removing larger impurities on the lens surface. The airflow can clean up these larger impurities, thereby avoiding scratches on the lens and the wiping cloth caused by these larger impurities during the subsequent wiping process, thereby better wiping the lens and protecting the wiping cloth.

[0203] S20, performing a first wiping process on the lens;

[0204] The second cleaning process is completed by pressing the wiping cloth against the lens surface with the first wiping head and wiping it, thereby removing smaller impurities and some impurities adhering to the lens surface.

[0205] S30, performing a second wiping process on the lens;

[0206] The third cleaning process is completed by wiping the impurities remaining on the lens after the first wiping process, thereby removing finer impurities, impurities adhering to the lens surface, and new impurities that may be generated by the first wiping process.

[0207] S40, performing a second air blowing process on the lens;

[0208] The fourth cleaning process is completed by using an airflow to blow directly onto the lens, with the aim of further removing new impurities that may be generated by the second wiping process. The impurities may have been firmly adhered to the lens surface, but have been detached after the first wiping process and the second wiping process and still remain on the lens surface. At this time, the use of airflow can clean up these impurities, thereby better cleaning the lens.

[0209] The above cleaning method performs a first air blowing treatment on the workpiece, then performs a second wiping treatment on the workpiece, then performs a second wiping treatment on the workpiece, and finally performs a second air blowing treatment on the workpiece. Through these four cleanings, a higher cleanliness of the workpiece is obtained to ensure that impurities on the surface of the workpiece are cleaned quickly.

[0210] In one embodiment, see Fig.13 When the lens 11 is fixed by the fixing device 40, the lens 11 and the fixing device are in a vertical state, and the first blowing treatment for the workpiece is to blow air vertically toward the surface of the lens 11. At this time, the airflow 50 blowing vertically toward the lens 11 can fully reach the surface of the lens 11, thereby achieving cleaning of the surface of the lens 11. In one embodiment, the blowing time is 4s-6s.

[0211] In one embodiment, see Fig.14 (A) and 14 (B), when the lens 11 is fixed by the fixing device 40, there is a groove between the lens 11 and the fixing device 40, and the first blowing treatment of the workpiece is to blow air at an acute angle to the surface of the lens 11. At this time, the air flow 50 with an angle blowing toward the lens can reach the groove, thereby achieving the cleaning of impurities located in the groove on the surface of the lens 11. In one embodiment, the blowing time is 4s-6s.

[0212] In one embodiment, see Fig.15 (A), 15(B) and 15(C), in step S10, the first air blowing treatment on the lens is not performed continuously, but air is blown to the lens intermittently, which can more effectively remove larger impurities on the lens surface.

[0213] In one embodiment, see Fig.15 (A) The first blowing process for the lens is:

[0214] Start blowing at time t0;

[0215] Stop blowing at time t1;

[0216] Start blowing at time t2;

[0217] Stop blowing at time t3;

[0218] Among them, t3-t0 is 4s-6s;

[0219] In this blowing process, the duration of each blowing may be unequal, and the duration of stopping blowing in the middle may also be different from the duration of blowing. By blowing, stopping blowing, and blowing for different durations, larger impurities can be easily cleaned away.

[0220] In one embodiment, see Fig.15 (B) The first blowing process for the lens is:

[0221] Start blowing at time 0;

[0222] Stop blowing at time t0;

[0223] Start blowing at 2t0;

[0224] Stop blowing at 3t0;

[0225] Among them, t0 is 1s-2s;

[0226] Under this blowing treatment, the duration of each blowing and the duration of stopping blowing in the middle can be equal. By blowing, stopping blowing, and blowing for equal durations, larger impurities can be cleaned up more easily.

[0227] In one embodiment, see Fig.15 (C) The first blowing process for the lens is:

[0228] Blow, keep the first time T1;

[0229] Stop blowing and keep the air for the second time T2;

[0230] Blow, keep the first time T1;

[0231] Among them, 2T1+T2 is 4s-6s;

[0232] In this blowing process, the duration of each blowing can be equal, but the duration of stopping blowing in the middle and the duration of a single blowing can be unequal. By blowing with equal duration and stopping blowing with unequal duration, larger impurities can be easily cleaned out.

[0233] In one embodiment, see Fig.16 When S20 performs the first cleaning process on the lens, it includes:

[0234] S210, causing the first wiping head to press the wiping cloth against the lens;

[0235] When the turntable rotates the component to the working position of the first wiping device, the regulator of the first driving member drives the first wiping head to descend. After descending to a certain distance, the first wiping head presses the wiping cloth to descend, and finally presses the wiping cloth to the lens surface on the component.

[0236] S220, introducing cleaning liquid into the wiping cloth;

[0237] When the first wiping head presses the wiping cloth against the lens, the liquid supply device provides cleaning liquid to the first channel, and the cleaning liquid is introduced into between the first wiping head and the wiping cloth through the first channel, so that the cleaning liquid can be introduced continuously or intermittently during the wiping process.

[0238] S230, causing the first wiping head to move along a preset trajectory;

[0239] After the cleaning liquid is introduced into the wiping cloth for the first time, the first wiping head is moved according to a preset trajectory, and the movement of the first wiping head drives the wiping cloth to wipe the lens.

[0240] By introducing the cleaning liquid between the first wiping head and the wiping cloth, the amount of the cleaning liquid introduced can be more accurately controlled, and the cleaning liquid can be introduced continuously or intermittently during the wiping process, so that the wiping effect is better, the cleaning efficiency and the cleanliness of the lens are improved.

[0241] In one embodiment, see Fig.17 When S20 performs the first cleaning process on the lens, it includes:

[0242] S210, causing the first wiping head to press the wiping cloth against the lens;

[0243] S220, introducing cleaning liquid into the wiping cloth;

[0244] S223, rotating the first wiping head;

[0245] After the first wiping head presses the wiping cloth against the lens and the cleaning liquid is introduced, the first wiping head rotates and keeps rotating until the wiping is finished. Through the cooperation of the rotation and the movement according to the preset trajectory, a more diversified wiping path of the wiping head is realized, and the rotational movement can increase the lateral shear force of the wiping head when wiping, so as to better clean the small-shaped impurities on the lens surface and some impurities adhering to the lens surface. Specifically, the driving mechanism 326 includes a first driving member 3261, a second driving member 3264 and a third driving member 3272, the first driving member 3261 is used to drive the first wiping head 321 to press against the wiping cloth 322, the second driving member 3264 is connected to the first driving member 3261, and is used to drive the first wiping head 321 to move according to the preset trajectory, the third driving member 3272 is connected to the first driving member 3261, and the first wiping head 321 is connected to the third driving member 3272 and rotates under the drive of the third driving member 3272.

[0246] S230, making the first wiping head move along a preset trajectory.

[0247] In one embodiment, see Fig.18When performing the first wiping process on the lens, S230 causes the first wiping head to move according to a preset trajectory, including:

[0248] S231, moving the first wiping head 321 along a first direction;

[0249] The second driving member 3264 includes a first direction driving member 3265 , and the first wiping head 321 moves along the first direction under the drive of the first direction driving member 3265 .

[0250] S232, moving the first wiping head 321 along the second direction;

[0251] The second driving member 3264 further includes a second direction driving member 3266 . The second direction driving member 3266 is connected to the first direction driving member 3265 . The first wiping head 321 moves along the second direction under the drive of the second direction driving member 3266 .

[0252] The first direction is perpendicular to the second direction.

[0253] When the first wiping head is wiping, it can move along a preset track under the drive of the second driving member as needed, and drive the wiping cloth to wipe the lens during the movement, which can provide a larger wiping force and obtain a better cleaning effect.

[0254] In one embodiment, when the lens is subjected to the first wiping treatment, the first wiping head may move according to a preset trajectory or the first wiping head may move in a first direction and a second direction at the same time. By simultaneously feeding the first wiping head in the first direction and the second direction, a more complex and excellent movement path of the first wiping head is achieved, so that a preset trajectory can be designed according to wiping requirements or different wiping objects.

[0255] In one embodiment, see Fig.19 When the lens is first wiped, the preset track may be a wiping track 60 formed from the center of the workpiece in a spiral outward direction. The wiping track 60 formed from the center of the workpiece in a spiral outward direction can wipe the surface of the lens 11 more comprehensively. Moreover, since the wiping track 60 is formed in a spiral outward direction, under the premise that the first wiping head 321 has a certain diameter, the first wiping head 321 will repeatedly wipe the lens 11 during the wiping process. Fig.19 The first wiping portion 70a, the intersection portion 70b and the second wiping portion 70c of the first wiping head 321 can be spread over the entire lens 11 during the wiping process of the first wiping head 321, thereby improving the cleaning effect, wherein 70a represents the position before the first wiping head 321 moves, 70c represents the position after the first wiping head 321 moves, and 70b represents the intersection of 70a and 70c.

[0256] In one embodiment, see Fig. 20 The first wiping head 321 has a certain diameter, and the diameter of the first wiping head 321 cannot be too large or too small. The first wiping head 321 needs to wipe the entire surface of the lens 11. Therefore, the preferred ratio of the diameter of the first wiping head 321 to the diameter of the lens 11 is 1:3-1:5. Under this ratio, the first wiping head 321 can better wipe the lens 11 while ensuring efficiency. The first wiping head 321 with a too large diameter cannot wipe the lens 11 well, and the first wiping head 321 with a too small diameter has a low wiping efficiency.

[0257] Through the above workpiece cleaning method, the first air blowing treatment can blow away larger impurities to prevent the lens surface from being scratched by larger impurities in the first wiping treatment. The first wiping treatment uses a cleaning liquid to complete wet wiping of the workpiece. The second wiping treatment wipes the impurities remaining in the lens after the first wiping treatment to remove smaller impurities, impurities adhering to the lens surface, and new impurities that may be generated by the first wiping treatment. The second air blowing treatment removes new impurities that may be generated by the second wiping treatment. By subjecting the lens to the first air blowing treatment, the first wiping treatment, the second wiping treatment, and the second air blowing treatment in sequence, the cleaning effect of the workpiece is achieved, and the workpiece's demand for high cleanliness is met.
