Description

Technical Field

[0001] The embodiment of the present invention relates to the field of automatic mounting technology, and in particular to an automatic mounting method for a camera assembly. Background Art

[0002] The mounting procedure of camera components usually includes cleaning and drying processes before mounting, as well as loading and mounting processes.

[0003] In the prior art, it is usually necessary to manually load the camera components to be mounted into a centrifugal water washing device for centrifugal cleaning and drying, and then manually unload, transfer and temporarily store the dried camera components. Then, manually take the camera components from the storage device in batches and multiple times and load them into the loading module of the mounting equipment.

[0004] However, since the camera assembly has very high cleanliness requirements, this means that the interval between each process should be strictly controlled to avoid the risk of contamination. In addition, the degree of manual intervention in the entire process should be reduced as much as possible. Otherwise, it is easy to cause contamination of the camera assembly and reduce the product yield. Summary of the invention

[0008] Optionally, a lens is accommodated in the cavity of the target camera assembly, and an angle between the spraying direction of the nozzle and the horizontal plane is determined based on a protrusion angle of the lens, wherein the larger the protrusion angle, the larger the angle.

[0009] Optionally, the target camera component is cleaned, including: pre-cleaning the target camera component for a first cleaning time using a first spray hydraulic pressure, a first nozzle jitter frequency, and a first liquid column diameter; and re-cleaning the target camera component for a second cleaning time using a second spray hydraulic pressure, a second nozzle jitter frequency, and a second liquid column diameter; wherein the first spray hydraulic pressure is greater than the second spray hydraulic pressure, the first nozzle jitter frequency is greater than the second nozzle jitter frequency, the first cleaning time is less than the second cleaning time, the first liquid column diameter is less than the diameter of the target camera component, and the second liquid column diameter is greater than the diameter of the target camera component.

[0010] Optionally, one or more of the following conditions are satisfied: the ratio of the first nozzle jitter frequency to the second nozzle jitter frequency is greater than or equal to 10; the ratio of the first liquid column diameter to the diameter of the target camera component is in the interval [1 / 2, 1); the ratio of the second liquid column diameter to the diameter of the target camera component is in the interval (1, 2]; the ratio of the first spray hydraulic pressure to the second spray hydraulic pressure is selected from [5, 10]; the ratio of the second cleaning time to the first cleaning time is selected from [2, 4].

[0011] Optionally, the multiple target camera components placed on the loading module are carried by multiple trays, each tray has a preset number of accommodating cavities, and each accommodating cavity is used to carry a single target camera component; after pre-cleaning the target camera component for a first cleaning time and before re-cleaning the target camera component for a second cleaning time, the method also includes: using a third liquid column diameter to clean the area between every two adjacent accommodating cavities of the tray; wherein the third liquid column diameter is less than or equal to the width of the area between every two adjacent accommodating cavities of the tray.

[0012] Optionally, the drying processing module includes a wind knife device and a heating device; the target camera component is dried, including: using the wind knife device to perform preliminary drying treatment on the target camera component for a first drying time; using the heating device to perform re-drying treatment on the target camera component for a second drying time; wherein, the first drying time is less than the second drying time, and the temperature of the preliminary drying treatment is less than the temperature of the re-drying treatment.

[0013] Optionally, the target camera assembly has a cavity; the opening of the cavity of the target camera assembly faces downward, and the air outlet of the wind knife device faces the opening of the cavity.

[0014] Optionally, the duration for cleaning the target camera component that is automatically transferred to the cleaning module once, and the duration for drying the target camera component that is automatically transferred to the drying module once, are both shorter than the duration for mounting the target camera component that is automatically transferred to the mounting module once.

[0015] Optionally, the multiple target camera components placed on the loading module are evenly divided into multiple groups, each group is carried by the same number of pallets, and a single tray of target camera components is automatically transferred each time; the method also includes: whenever the remaining number of groups of target camera components of the loading module reaches a preset proportion of the total number of groups of target camera components placed on the loading module, a loading prompt signal is issued, and the loading prompt signal is used to prompt the user to load; wherein the preset proportion is determined based on the time consumed for loading the target camera components and the total time for cleaning, drying and mounting a single group of target camera components.

[0016] Optionally, the camera assembly is selected from: a lens assembly, an IR assembly and a voice coil motor VCM.

[0017] Compared with the prior art, the technical solution of the embodiment of the present invention has the following beneficial effects:

[0018] In an embodiment of the present invention, an automated transfer method is adopted, and the first interval between the cleaning of the target camera component and the drying of the target camera component, and the second interval between the drying of the target camera component and the mounting of the target camera component are strictly controlled. However, the prior art relies on manual transfer, which makes the interval between each operation uncontrollable. The interval may be as long as 30 minutes to 1 hour or even longer, and manual intervention is prone to increase the probability of contamination. In contrast, in the automatic mounting scheme of the embodiment of the present invention, the interval between each operation is highly controllable, and the first interval and the second interval are controlled to be less than or equal to 5 minutes. Therefore, by significantly shortening the interval, the risk of secondary contamination of the target camera component in the time gap between the cleaning operation and the drying operation, and the time gap between the drying operation and the mounting operation can be minimized, so that the device can be used immediately after washing, thereby improving the cleanliness of the device. Further, the yield of the device is improved.

[0019] Furthermore, in an embodiment of the present invention, by setting the cavity opening of the target camera assembly to face downward, that is, the opening direction of the cavity is consistent with the direction of gravity, impurities can be removed by the gravity of the spray liquid, thereby improving the efficiency and effect of cleaning.

[0020] Furthermore, in the embodiment of the present invention, compared with conventional devices, the lens of the target camera assembly has very high requirements for clarity and smoothness, therefore, the angle between the spray direction of the nozzle and the horizontal plane is determined based on the protrusion angle of the lens, wherein the larger the protrusion angle, the larger the angle. Compared with flushing at other inappropriate angles (for example, directly using a direction perpendicular to the horizontal plane, that is, the direction opposite to the direction of gravity), the damage of the spray liquid to the lens during the spraying process can be reduced, ensuring the smoothness and clarity of the mirror surface.

[0021] Furthermore, in the process of cleaning the target camera assembly, at least two rounds of cleaning operations, pre-cleaning and re-cleaning, are set, and a relatively larger spray hydraulic pressure, nozzle jitter frequency and a shorter cleaning time are used in the pre-cleaning operation, and a relatively smaller spray hydraulic pressure, nozzle jitter frequency and a longer cleaning time are used in the re-cleaning operation, that is, "high hydraulic pressure and high flow rate fast washing + low hydraulic pressure and low flow rate slow washing" are combined. Among them, the main purpose of pre-cleaning is to quickly remove a large amount of impurities, and the main purpose of re-cleaning is to continue to remove tiny particles and further improve the cleanliness. Compared with the single-round cleaning method or the two-round cleaning without stepped cleaning parameters in the conventional cleaning process, the use of this implementation scheme helps to significantly improve the cleaning effect and improve the cleanliness of the device.

[0022] Furthermore, in the pre-cleaning operation, the diameter of the first liquid column is set to be smaller than the diameter of the target camera component, so that a single target camera component (especially the cavity and the lens) can be cleaned in sequence and concentratedly (especially the cavity and the lens) so as to quickly remove a large amount of impurities. In the re-cleaning operation, the diameter of the second liquid column is set to be larger than the diameter of the target camera component, so that the middle area of ​​the single target camera component (for example, the accommodating cavity and the lens area) can be re-cleaned (for example, the accommodating cavity and the lens area) so as to continue to remove small particles, and the surrounding area of ​​the target camera component and the area between two adjacent target camera components can be cleaned so as to further improve the cleaning effect.

[0023] Furthermore, in the embodiment of the present invention, the above-mentioned intermediate cleaning operation is arranged between the pre-cleaning operation and the re-cleaning operation, and the diameter of the cleaning liquid column (i.e., the third liquid column diameter) is set to be less than or equal to the width of the area between every two adjacent accommodating cavities of the tray, so as to centrally remove impurities in the area between every two adjacent accommodating cavities. In this way, it is helpful to avoid secondary contamination of the cleaned target camera assembly by dirt in the area between the accommodating cavities, and further improve the cleanliness of the target camera assembly.

[0024] Furthermore, in the process of drying the target camera component, a preliminary drying process and at least two rounds of drying operations in the drying process are set, and the two rounds of drying processes adopt different drying methods. Specifically: the "air drying" drying principle is adopted in the preliminary drying operation, and a relatively longer drying time and a lower temperature are set; the "drying" drying principle is adopted in the re-drying operation, and a relatively shorter drying time and a higher temperature are set, that is, "low-temperature air drying + high-temperature drying" is combined.

[0025] The main purpose of the initial drying is to use the blowing effect to quickly remove a large amount of spray liquid. In addition, since the spray liquid often contains some particles, if a higher temperature is used, the liquid may evaporate too quickly, causing the particles to still adhere to the target camera component. Therefore, a relatively low temperature should be set during the air drying process. The main purpose of the re-drying is to further set a relatively high temperature to quickly dry the target camera component on the basis of the initial air drying having removed a large amount of liquid and removed particles at the same time, so as to increase the drying speed as much as possible while ensuring cleanliness. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 is a flow chart of an automatic mounting method of a camera assembly in an embodiment of the present invention;

[0027] Figure 2 yes Figure 1 A flowchart of a specific implementation of step S12 in FIG. DETAILED DESCRIPTION

[0028] In order to make the above-mentioned purposes, features and beneficial effects of the embodiments of the present invention more obvious and understandable, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 , Figure 1 The flowchart of the automatic mounting method of a camera assembly in an embodiment of the present invention is shown in FIG. The target camera assembly can be selected from, but not limited to, a lens assembly, an infrared (IR) assembly, and a voice coil motor (VCM).

[0030] The automatic placement method may include steps S11 to S14:

[0031] Step S11: placing a plurality of target camera components on a loading module;

[0032] Step S12: automatically transferring the target camera assembly to a cleaning module, so as to clean the target camera assembly by the cleaning module;

[0033] Step S13: within a first interval after the target camera component is cleaned, automatically transferring the target camera component to a drying processing module, so as to dry the target camera component by the drying processing module;

[0034] Step S14: within a second time interval after the drying process of the target camera component is completed, the target camera component is automatically transferred to a mounting module so that the target camera component is mounted by the mounting module.

[0035] The first interval duration and the second interval duration are both less than or equal to 5 minutes.

[0036] In this embodiment, the feeding module, cleaning module, drying module and mounting module can be arranged in an integrated automatic mounting device in combination with the actual application scenario, or each module can be arranged in a different device. It should be pointed out that the distance between the above modules should not be too far, otherwise it may increase the transfer interval of the target camera component between the modules, thereby reducing efficiency, increasing the risk of secondary contamination, and affecting cleanliness.

[0037] In the specific implementation of step S11, manual loading or mechanized automatic loading can be adopted to place the multiple target camera components on the loading module.

[0038] In a specific implementation, multiple trays may be used to carry the multiple target camera components, each tray having a preset number of accommodating cavities, each accommodating cavity may be used to carry a single target camera component. Without limitation, the number of accommodating cavities on each tray (i.e., the preset number) may be selected from the interval [50, 100].

[0039] Among them, each pallet can be placed layer by layer, and each layer can hold a single pallet, and 10 to 20 pallets can be loaded each time. Subsequently, the preset number of target camera components can be automatically transferred, cleaned, dried, and mounted on a single pallet basis each time. In this way, compared with automatically transferring and processing a single target camera component at a time, the use of pallet loading can realize the processing of multiple target camera components at a time, thereby improving the overall efficiency of the process.

[0040] In the prior art, the loading module, cleaning module, drying processing module, etc. are usually arranged inside the same device and adjacent to each other, and the loading is performed by opening and closing the device door. When loading, the upper body of the human body will extend into the device, thereby significantly increasing the risk of impurity contamination caused by the human body. In contrast, in the embodiments of the present invention, any of the following methods can be used to reduce the risk of human contamination during the loading process.

[0041] In a specific embodiment, the loading module can be arranged on the external side of the integrated automatic placement device. For example, a push-pull loading platform can be used, and when the loading platform is in a pulled-out state, the multiple target camera components are placed on the loading platform; then, the loading platform with the target camera components placed thereon is pushed into the interior of the integrated automatic placement device.

[0042] In another specific implementation, the loading module and other modules may be arranged in different equipment, or in different closed spaces of the same equipment, so as to isolate the loading module from other modules.

[0043] In the specific implementation of step S12, the target camera assembly can be automatically transferred between modules by using, but not limited to, automatic grippers or robotic arm devices, automatic conveying devices (for example, conveyor belts, guide rails, etc.) in combination with actual application scenario needs.

[0044] Furthermore, the target camera assembly has a cavity, and the cleaning module includes a spray device; cleaning the target camera assembly includes: using the spray device to spray-rinse the target camera assembly; wherein the opening of the cavity of the target camera assembly faces downward, and the nozzle of the spray device faces the opening of the cavity.

[0045] In the embodiment of the present invention, by setting the cavity opening of the target camera assembly to face downward, that is, the opening direction of the cavity is consistent with the direction of gravity, impurities can be removed by the gravity of the spray liquid, thereby improving the efficiency and effect of cleaning.

[0046] Furthermore, a lens is accommodated in the cavity of the target camera assembly, and an angle between the spraying direction of the nozzle and the horizontal plane is determined based on a protrusion angle of the lens, wherein the larger the protrusion angle, the larger the angle.

[0047] The convex angle of the lens is also called the convexity of the lens. Taking the lens as a convex lens as an example, the larger the convex angle, the greater the convex degree of the convex lens, and vice versa. In a specific implementation, the convex angle of the lens can be calculated using the following formula: θ=(1 / f)×100; wherein θ represents the convex angle of the lens, and f represents the focal length of the lens.

[0048] In the embodiment of the present invention, compared with conventional devices, the lens of the target camera assembly has very high requirements for clarity and smoothness. Therefore, the angle between the spray direction of the nozzle and the horizontal plane is determined based on the protrusion angle of the lens, wherein the larger the protrusion angle, the larger the angle. Compared with flushing at other inappropriate angles (for example, directly using a direction perpendicular to the horizontal plane, that is, the direction opposite to the gravity direction), the damage of the spray liquid to the lens during the spraying process can be reduced, ensuring the smoothness and clarity of the mirror surface.

[0049] Furthermore, the nozzle can be set to rotate with the center point of the lens as the center, and the external tangent surface obtained by the ray centered on the position of the nozzle and the lateral convex surface of the lens is determined, and the angle between the external tangent surface and the horizontal plane is used as the angle between the spraying direction of the nozzle and the horizontal plane.

[0050] In an embodiment of the present invention, for lenses that are easily damaged (especially convex lenses), the spray direction can be set to be consistent with the direction of the external cut surface so that the spray liquid falls as close to the lens as possible to improve the cleaning effect, and the spray liquid is prevented from being sprayed directly onto the lens, thereby effectively reducing damage.

[0051] Reference Figure 2 , Figure 2 The flowchart of a specific implementation of step S12 is shown in FIG. 1 . In step S12, the target camera assembly is cleaned, which may specifically include steps S21 to S22.

[0052] In step S21, the target camera assembly is pre-cleaned for a first cleaning time using a first spray hydraulic pressure, a first nozzle jitter frequency, and a first liquid column diameter.

[0053] In step S22, the target camera assembly is re-cleaned for a second cleaning time using a second spray hydraulic pressure, a second nozzle jitter frequency, and a second liquid column diameter.

[0054] Among them, the first spray hydraulic pressure is greater than the second spray hydraulic pressure, the first nozzle jitter frequency is greater than the second nozzle jitter frequency, the first cleaning time is less than the second cleaning time, the first liquid column diameter is less than the diameter of the target camera component, and the second liquid column diameter is greater than the diameter of the target camera component.

[0055] In an embodiment of the present invention, at least two rounds of cleaning operations, pre-cleaning and re-cleaning, are provided, and a relatively larger spray hydraulic pressure, nozzle jitter frequency, and a shorter cleaning time are used in the pre-cleaning operation, and a relatively smaller spray hydraulic pressure, nozzle jitter frequency, and a longer cleaning time are used in the re-cleaning operation, that is, a combination of "high hydraulic pressure and high flow rate fast washing + low hydraulic pressure and low flow rate slow washing". Among them, the main purpose of pre-cleaning is to quickly remove a large amount of impurities, and the main purpose of re-cleaning is to continue to remove tiny particles and further improve the cleanliness. Compared with the single-round cleaning method used in conventional cleaning processes or the lack of stepped cleaning parameters in two rounds of cleaning, the use of this implementation scheme helps to significantly improve the cleaning effect and improve the cleanliness of the device.

[0056] Furthermore, in the pre-cleaning operation, the diameter of the first liquid column is set to be smaller than the diameter of the target camera component, so that a single target camera component (especially the cavity and the lens) can be cleaned in sequence and concentratedly (especially the cavity and the lens) so as to quickly remove a large amount of impurities. In the re-cleaning operation, the diameter of the second liquid column is set to be larger than the diameter of the target camera component, so that the middle area of ​​the single target camera component (for example, the accommodating cavity and the lens area) can be re-cleaned (for example, the accommodating cavity and the lens area) so as to continue to remove small particles, and the surrounding area of ​​the target camera component and the area between two adjacent target camera components can be cleaned so as to further improve the cleaning effect.

[0057] Without limitation, one or more of the following conditions are satisfied: the ratio of the first nozzle jitter frequency to the second nozzle jitter frequency is greater than or equal to 10; the ratio of the first liquid column diameter to the diameter of the target camera component is in the interval [1 / 2, 1); the ratio of the second liquid column diameter to the diameter of the target camera component is in the interval (1, 2]; the ratio of the first spray hydraulic pressure to the second spray hydraulic pressure is selected from [5, 10]; the ratio of the second cleaning time to the first cleaning time is selected from [2, 4].

[0058] Furthermore, the multiple target camera components placed on the loading module are carried by multiple trays, each tray has a preset number of accommodating cavities, and each accommodating cavity is used to carry a single target camera component; after pre-cleaning the target camera component for a first cleaning time and before re-cleaning the target camera component for a second cleaning time, the method also includes: using a third liquid column diameter to clean the area between every two adjacent accommodating cavities of the tray; wherein the third liquid column diameter is less than or equal to the width of the area between every two adjacent accommodating cavities of the tray.

[0059] In the embodiment of the present invention, the above-mentioned intermediate cleaning operation is arranged between the pre-cleaning operation and the re-cleaning operation, and the diameter of the cleaning liquid column (i.e., the third liquid column diameter) is set to be less than or equal to the width of the area between every two adjacent accommodating cavities of the tray, so as to centrally remove impurities in the area between every two adjacent accommodating cavities. In this way, it is helpful to avoid secondary contamination of the cleaned target camera assembly by dirt in the area between the accommodating cavities, and further improve the cleanliness of the target camera assembly.

[0060] Continue to refer to Figure 1 In the specific implementation of step S13, the interval between cleaning the target camera component and drying the target camera component (i.e., the first interval) should not be too long. Otherwise, the target camera component that has been cleaned is prone to the risk of secondary contamination within a longer interval, thereby affecting the previous cleaning effect.

[0061] It should be pointed out that in the prior art, it is usually necessary to manually load the camera components to a separate cleaning device (for example, a centrifugal water washing device) for cleaning. After cleaning, the materials are manually taken out and transferred to a drying treatment device for drying. In this process, the high reliance on manual labor easily increases the probability of contamination, and the interval duration is non-fixed and uncontrollable. In comparison, the embodiment of the present invention adopts an automated transfer method, which is free from manual intervention and the interval duration is more controllable. The first interval duration can be strictly controlled to be less than or equal to 5 minutes. In this way, the risk of contamination can be minimized and the cleaning effect can be guaranteed.

[0062] Furthermore, the drying processing module includes a wind knife device and a heating device; the target camera component is dried, including: using the wind knife device to perform preliminary drying processing on the target camera component for a first drying time; using the heating device to perform re-drying processing on the target camera component for a second drying time; wherein, the first drying time is less than the second drying time, and the temperature of the preliminary drying processing is less than the temperature of the re-drying processing.

[0063] It is understandable that the blowing air pressure of the wind knife device should not be too small, otherwise the expected drying effect cannot be achieved and the drying time will be increased; the blowing air pressure should not be too large, otherwise the fine droplets generated during the blowing process may move too fast and cause damage to the target camera components (especially the lens).

[0064] Without limitation, the temperature of the preliminary drying treatment can be selected from the interval [25°C, 40°C], the first drying time can be selected from the interval [30s, 50s], the temperature of the re-drying treatment can be selected from the interval [40°C, 75°C], and the second drying time can be selected from the interval [60s, 80s].

[0065] In an embodiment of the present invention, a preliminary drying treatment and at least two rounds of drying operations in the drying treatment are provided, and the two rounds of drying treatment adopt different drying methods, specifically: the "air drying" drying principle is adopted in the preliminary drying operation, and a relatively longer drying time and a lower temperature are set; the "drying" drying principle is adopted in the re-drying operation, and a relatively shorter drying time and a higher temperature are set, that is, a combination of "low-temperature air drying + high-temperature drying".

[0066] The main purpose of the initial drying is to use air to quickly remove a large amount of spray liquid. In addition, since the spray liquid often contains some particles, if a higher temperature is used, the liquid may evaporate too quickly, causing the particles to still adhere to the target camera component. Therefore, a relatively low temperature should be set during the air drying process. The main purpose of re-drying is to further set a relatively high temperature to quickly dry the target camera component on the basis of removing a large amount of liquid and particles by the initial air drying, so as to increase the drying speed as much as possible while ensuring cleanliness.

[0067] Furthermore, the target camera assembly has a cavity; the opening of the cavity of the target camera assembly faces downward, and the air outlet of the wind knife device faces the opening of the cavity.

[0068] In the embodiment of the present invention, since liquid is easily stored inside the cavity of the target camera assembly and is difficult to dry, setting the air outlet of the wind knife device toward the opening of the cavity helps to maximize the contact area between the interior of the cavity and the air, thereby improving the drying efficiency.

[0069] In the specific implementation of step S14, regarding the setting of the second interval duration and its related principles and technical effects, refer to the relevant description of the first interval duration in step S13, which will not be repeated here.

[0070] Furthermore, the duration for cleaning the target camera component that is automatically transferred to the cleaning module once, and the duration for drying the target camera component that is automatically transferred to the drying module once, are both shorter than the duration for mounting the target camera component that is automatically transferred to the mounting module once.

[0071] As a non-limiting embodiment, the duration of cleaning the target camera assembly of a single tray and the duration of drying the target camera assembly of the single tray may be controlled to be less than or equal to 2 minutes.

[0072] In the embodiment of the present invention, by setting the cleaning efficiency and the drying efficiency to be faster than the mounting efficiency, the process rhythm can be met, and the number of cleaning and drying processes of the target camera components can be matched with the number of chips to be mounted in real time. Furthermore, after each mounting of the current batch of target camera components, the next batch of target camera components to be mounted that have completed the cleaning and drying processes can be directly obtained without wasting time waiting, thereby improving process efficiency.

[0073] Furthermore, the multiple target camera components placed on the loading module are evenly divided into multiple groups, each group is carried by the same number of trays, and a single tray of target camera components is automatically transferred each time; the method also includes: whenever the remaining number of groups of target camera components of the loading module reaches a preset proportion of the total number of groups of target camera components placed on the loading module, a loading prompt signal is issued, and the loading prompt signal is used to prompt the user to load; wherein the preset proportion is determined based on the time consumed for loading the target camera components and the total time for cleaning, drying and mounting a single group of target camera components.

[0074] As a non-limiting embodiment, the multiple target camera components placed in the loading module are evenly divided into n groups, the total time for cleaning, drying and mounting a single group of target camera components is about t1, and the loading time of the target camera components is about t2, then the preset ratio can be set to about t2 / (t1×n). For example, n=2, t1=30min, t2=30min, then the preset ratio can be set to 1 / 2.

[0075] In the embodiment of the present invention, by sending out a feeding prompt signal in advance at an appropriate time before all the target camera components of the current batch are processed, the feeding operation of the next batch of target camera components and the processing of the remaining target camera components of the current batch can be executed in parallel, that is, the feeding operation does not interfere with the cleaning, drying and mounting operations. Furthermore, through grouping settings, it is helpful to more conveniently and accurately control the time node of sending the feeding prompt signal, ensure that sufficient feeding time is reserved, and avoid production capacity loss caused by untimely feeding.

[0076] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
