Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical sensor packaging, and in particular to a dust removal device for optical imaging sensors. Background Technology
[0002] In the field of optical sensor packaging, optical imaging sensors require structural packaging and functional testing. This manufacturing process necessitates a cleanroom environment. However, with equipment operation and product movement, movable dust inevitably falls onto the products.

Furthermore, the dust particles are extremely small, ranging from 0.5 to 10 μm (invisible to the naked eye). Therefore, conventional cleaning methods and increasing cleaning frequency are largely ineffective. Utility Model Content

[0039] The following is for reference. Figures 1-5 A dust removal device for an optical imaging sensor is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.
[0040] like Figures 1-5 As shown, an optical imaging sensor dust removal device includes a feeding mechanism and a dust collection mechanism.
[0041] The feeding mechanism includes a turntable 100 and a motor 110 that drives the turntable 100 to rotate. Specifically, the motor 110 is a servo motor. The turntable 100 has multiple acupoints 120 for placing optical imaging sensors, and the shape of the acupoints 120 must match the shape of the optical imaging sensors. The dust collection mechanism includes a mounting bracket and a magnetic component 130. The mounting bracket includes a vertical plate 140 and a cantilever 150. The vertical plate 140 is erected next to the turntable 100, and the cantilever 150 is connected to the top of the vertical plate 140 and located above the turntable 100. The magnetic component 130 is located on the bottom surface of the cantilever 150 and is used to adsorb iron-containing dust from the optical imaging sensors. It is worth noting that the magnetic component 130 is a magnet. Using a magnet makes the magnetic component 130 easy to process and provides strong magnetic force, effectively adsorbing iron-containing dust from the optical imaging sensors. Of course, other ferromagnetic materials can also be used for the magnetic component 130. During operation, the feeding mechanism drives the turntable 100 to rotate via motor 110. Optical imaging sensors are sequentially placed into the acupoints 120 on the turntable 100, and then pass through a dust collection mechanism mounted next to the turntable 100 via a vertical plate 140. A cantilever 150 is connected to the vertical plate 140 and positioned above the turntable 100. This allows the magnetic component 130 on the bottom surface of the cantilever 150 to attract iron-containing dust from the passing optical imaging sensors. After each operation, the magnetic component 130 is routinely cleaned, achieving continuous and effective cleaning. It should be noted that loading and unloading mechanisms, such as robotic arms, are required on both sides of the turntable 100. Before dust collection, the optical imaging sensors are placed into the acupoints 120, and after dust collection, they are removed from the acupoints 120. Therefore, this optical imaging sensor dust removal device can achieve non-contact cleaning of iron-containing dust on optical imaging sensors, improving the product yield of optical imaging sensors.
[0042] like Figure 2 As shown, the feeding mechanism also includes a worktable 160, with a motor 110 mounted on top of the worktable 160 and a vertical plate 140 mounted on the side of the worktable 160. The worktable 160 provides a mounting position for the motor 110, facilitating its fixation and installation. Furthermore, the feeding mechanism includes a base 170, which is connected to the output shaft of the motor 110, and a turntable 100 is mounted on the base 170. The base 170 facilitates the mounting of the turntable 100 and its connection to the output shaft of the motor 110.
[0043] like Figure 3 As shown, two cantilever arms 150 are provided, one on each side of the upright plate 140. The two cantilever arms 150 allow for the installation of more magnetic components 130, enabling each optical imaging sensor to pass under more magnetic components 130, resulting in better adsorption. Specifically, the cantilever arm 150 is arc-shaped, and multiple magnetic components 130 are arranged evenly on the bottom surface of the cantilever arm 150 above the acupoint 120. The arc shape of the cantilever arm 150 facilitates matching with the shape of the turntable 100, and the evenly distributed magnetic components 130 on the bottom surface of the cantilever arm 150 improve the adsorption effect on iron-containing dust. Figure 5 As shown, the bottom surface of the cantilever 150 is provided with a mounting groove 180 for accommodating the magnetic component 130, and the top surface of the cantilever 150 is provided with a threaded hole 190 communicating with the mounting groove 180. The top surface of the magnetic component 130 is provided with a threaded rod 200 that is connected and fixed to the threaded hole 190. The mounting groove 180 on the bottom surface of the cantilever 150 facilitates the accommodating of the magnetic component 130, and the threaded rod 200 on the top surface of the magnetic component 130 cooperates with the threaded hole 190 of the mounting groove 180 for convenient installation and fixation.
[0044] Specifically, such as Figures 3-5As shown, the mounting bracket also includes a clamping block 210. The bottom surface of the clamping block 210 has a clamping groove 220 that mates with the top of the upright plate 140. The front side of the clamping block 210 has a boss 230 for mounting the cantilever 150. The clamping groove 220 on the clamping block 210 facilitates connection with the upright plate 140, and the boss 230 on the front side of the clamping block 210 facilitates mounting the cantilever 150, thereby connecting and fixing the cantilever 150 to the upright plate 140. Furthermore, the side of the upright plate 140 is provided with a side screw hole 240, the front side of the upright plate 140 is provided with a front screw hole 250, the side of the clamping block 210 is provided with a side waist-shaped hole 260 and an X-direction locking screw 270 that cooperates with the side screw hole 240 for installation, the front side of the clamping block 210 is provided with a front waist-shaped hole 280 and a Y-direction locking screw 290 that cooperates with the front screw hole 250 for installation, and the top surface of the clamping block 210 is provided with an upper screw hole 300 and a height adjustment screw 310 that abuts against the top surface of the upright plate 140. The top surface of the clamping block 210 has an upper screw hole 300 and a height adjustment screw 310 that abuts against the top surface of the upright plate 140 to adjust the height of the clamping block 210, thereby adjusting the height of the cantilever 150 and the magnetic component 130. The side of the clamping block 210 has a side waist-shaped hole 260 and an X-direction locking screw 270 that mates with the side screw hole 240 to fix the clamping block 210 in the X direction. The front side of the clamping block 210 has a front waist-shaped hole 280 and a Y-direction locking screw 290 that mates with the front screw hole 250 to fix the clamping block 210 in the Y direction. It should be noted that the boss 230 has two pin holes 320 and a bolt hole 330. The bottom surface of the cantilever 150 has two pins 340 that mate with the two pin holes 320. The cantilever 150 has a mounting hole 360 and a fixing bolt 350 that mates with the bolt hole 330 for installation. The boss 230 is provided with a pin hole 320, which is conducive to the positioning and mating with the bottom surface of the cantilever 150. The boss 230 is provided with a bolt hole 330, which is conducive to the tightening and fixing with the mounting hole 360 of the cantilever 150 by the fixing bolt 350.
