[0057] The following is in conjunction with the appendix Figures 1-9 This invention describes a cleaning device and a camera module assembly equipment according to an embodiment of the present invention.

[0058] This utility model aims to provide an embodiment of a cleaning device and a camera module assembly equipment.

[0059] In this embodiment, the camera module assembly equipment includes a cleaning device.

[0060] Reference Figure 1 , Figure 2 and Figure 3 The cleaning device includes a tray 100, a capping assembly 130, and a cleaning base 140.

[0061] Reference Figure 4 For the tray 100, the top of the tray 100 has a positioning groove 110 for positioning the lens. The bottom of the positioning groove 110 has a cleaning channel 120 that runs vertically through the tray 100, thereby facilitating the positioning of the lens by the cleaning device. At the same time, the cleaning channel 120 that runs vertically through the tray 100 is provided at the bottom of the positioning groove 110 so that the tray 100 can avoid the bottom of the lens, making it convenient for the cleaning device to clean the bottom of the lens.

[0062] In some specific embodiments, the cleaning channel 120 is a square hole, which allows the cleaning channel 120 to cover a larger area of ​​the bottom of the lens, thereby improving the cleaning range of the bottom of the lens.

[0063] Reference Figure 5 , Figure 6 and Figure 7The cover assembly 130 is located above the tray 100. The cover assembly 130 is used to press the top of the lens, thereby facilitating the cleaning device to fix the lens and preventing the lens from falling off the cleaning device during the cleaning process.

[0064] Specifically, the capping assembly 130 includes an upper plate 190, a lower plate 200, a pressure head 220, and a first spring 230. The lower plate 200 is connected to the bottom of the upper plate 190, and the bottom surface of the lower plate 200 is used to abut against the tray 100. The lower plate 200 has a through mounting hole 210. The pressure head 220 is disposed in the mounting hole 210 and can slide up and down in the mounting hole 210. The first spring 230 is located between the upper plate 190 and the pressure head 220 and is used to squeeze the pressure head 220 to press the lens.

[0065] Understandably, when the cover assembly 130 presses the lens, the pressure head 220 comes into contact with the lens, and the lens pushes the pressure head 220 back to compress the first spring 230. The elastic force generated by the deformation of the first spring 230 can drive the pressure head 220 to press the lens. On the one hand, this allows the cover assembly 130 to press the lens and prevent the lens from falling out of the positioning groove 110. On the other hand, the pressure head 220 has room to retract, which can prevent the pressure head 220 from damaging the lens.

[0066] Furthermore, the mounting hole 210 includes a large-diameter hole section 240 and a small-diameter hole section 250 arranged vertically, and the pressure head 220 includes a large-diameter part 260 and a small-diameter part 270 arranged vertically. The outer diameter of the large-diameter part 260 is larger than the hole diameter of the small-diameter hole section 250, and the large-diameter part 260 abuts against the top surface of the small-diameter hole section 250 to prevent it from falling off.

[0067] Understandably, when the pressure head 220 is pressed against the lens, the lens squeezes the pressure head 220 backward, and the large diameter portion 260 separates from the top surface of the small diameter section 250, allowing the pressure head 220 to move backward. After the pressure head 220 releases the lens, the first spring 230 pushes the pressure head 220 to move downward relative to the lower plate 200. At this time, the large diameter portion 260 can abut against the top surface of the small diameter section 250, thereby preventing the pressure head 220 from disengaging downward from the mounting hole 210.

[0068] In some specific embodiments, two connecting rods are rotatably arranged above the upper plate 190, and each connecting rod is provided with a hook. The hooks on the two connecting rods extend from both sides of the upper plate 190 to the lower plate 200. The upper plate 190 is also provided with two pressure rods and a power source connection part. One end of the two pressure rods is connected to the two connecting rods respectively. The power source connection part is used to connect to a power source. The power source drives the power source connection part to make the power source connection part drive the other end of the two pressure rods to swing, so that the two pressure rods drive the two connecting rods to rotate, so that the hooks on the two connecting rods swing to release the tray 100, thereby facilitating the release of the pressure cap assembly 130 and the tray 100 from each other.

[0069] Specifically, the power source can be set as a power component that can achieve linear drive, such as a cylinder or hydraulic cylinder.

[0070] Furthermore, a second spring is also provided on the upper plate 190. The second spring is used to support the bottom between the two ends of the pressure rod. Thus, when the power source connection part releases the two pressure rods, the second spring can support the pressure rod to swing in the opposite direction to drive the hook to clamp the tray 100, thereby making the cover assembly 130 and the tray 100 firmly connected.

[0071] In some specific embodiments, the top of the upper plate 190 is also provided with a clearance groove. The clearance groove is located below the power source connection part. The clearance groove is used to avoid the pressure rod. Thus, when the power source connection part drives the end of the pressure rod to move to the lowest position, the opening position of the hook is the largest. At this time, the clearance groove can avoid the pressure rod and prevent the pressure rod from interfering with the upper plate 190.

[0072] Reference Figure 8 and Figure 9 For the cleaning base 140, the cleaning base 140 is located below the tray 100. The cleaning base 140 has an air blowing channel 150 and a negative pressure exhaust channel 160. The air blowing port 170 of the air blowing channel 150 faces the cleaning channel 120. The tray 100 is reciprocated relative to the cleaning base 140 in a first direction so that the air blowing port 170 blows air towards the bottom of the lens for cleaning. The air suction port 180 of the negative pressure exhaust channel 160 is located below the tray 100. The negative pressure exhaust channel 160 is used to suck up and discharge exhaust gas.

[0073] Understandably, when the tray 100 moves back and forth relative to the cleaning base 140 in the first direction, the air outlet 170 can repeatedly blow air towards the bottom of the lens, thereby cleaning the glass filter at the bottom of the lens and ensuring the yield rate of the assembled camera module. At the same time, the air extraction port 180 of the negative pressure exhaust channel 160 draws exhaust air from the bottom of the lens below the tray 100, which helps to remove foreign objects that have fallen off the glass filter at the bottom of the lens in a timely manner, and prevents foreign objects blown off the glass filter from re-adhering to the glass filter under the airflow blown out by the air outlet 170, thereby helping to keep the glass filter clean.

[0074] In some specific embodiments, the length direction of the air outlet 170 is perpendicular to the first direction. Therefore, when the tray 100 moves back and forth relative to the cleaning base 140 along the first direction, the width of the airflow blown out by the air outlet 170 is larger, which can cover a larger area of ​​the bottom of the lens. This helps to increase the cleaning range of the bottom of the lens and improve the cleaning effect of the bottom of the lens.

[0075] Specifically, the shape of the air inlet 170 can be set as a strip-shaped hole.

[0076] In some specific embodiments, the tray 100 is provided with a plurality of positioning grooves 110 along a direction that is horizontal and perpendicular to the first direction, and the air blowing channel 150 is provided with a plurality of air blowing ports 170 arranged in a direction that is horizontal and perpendicular to the first direction, thereby enabling the cleaning device to clean multiple lenses at the same time, thereby improving efficiency.

[0077] In some specific embodiments, multiple air blowing channels 150 are provided, and the multiple air blowing channels 150 are arranged sequentially along the first direction. Thus, when the tray 100 moves back and forth relative to the cleaning base 140 along the first direction, the air blowing ports 170 of the multiple air blowing channels 150 can sequentially blow air to the bottom of the lens for cleaning, thereby improving the cleaning effect.

[0078] In some specific embodiments, the tray 100 is provided with a plurality of positioning grooves 110 along the first direction, thereby increasing the capacity of the cleaning device for the lens and improving efficiency. On the other hand, when the tray 100 moves back and forth relative to the cleaning base 140 along the first direction, the air outlet 170 can blow air to clean the plurality of positioning grooves 110 in the first direction.

[0079] In some specific embodiments, the negative pressure exhaust channel 160 is located between two adjacent air blowing channels 150. The negative pressure exhaust channel 160 extends vertically through the cleaning base 140, and the top of the negative pressure exhaust channel 160 forms an air extraction port 180. This makes the distance between the air extraction port 180 and the air blowing port 170 closer, which is conducive to smooth airflow between the air blowing channel 150, the bottom of the lens, and the negative pressure exhaust channel 160, reducing the occurrence of air turbulence. Consequently, it is beneficial for foreign objects detached from the bottom of the lens to be discharged towards the negative pressure exhaust channel 160 along the airflow direction.

[0080] In some specific embodiments, the width of the top of the negative pressure exhaust channel 160 gradually widens upwards, thereby making the suction area of ​​the suction port 180 larger, which in turn facilitates the discharge of foreign objects that fall off the bottom of the lens and the removal of exhaust gas.
