Description

Technical Field

[0001] This utility model relates to the field of digital product cleaning equipment technology, and in particular to a CCD wiping mechanism. Background Technology

[0002] CCD, short for Charge-Coupled Device, is a semiconductor device used to capture light and convert it into electronic signals. It is widely used in digital cameras, camcorders, scanners, medical imaging equipment, and other fields.

[0003] During the camera manufacturing process, to protect the CCD, an electrostatic film is applied to the CCD when the PCB board arrives. This film needs to be removed before assembling the lens, and then the CCD needs to be wiped clean. The cleanliness of the CCD determines whether there are defects such as black spots in the camera image, which is very important.

[0004] For example, the digital SLR camera CCD / CMOS and lens cleaning stick disclosed in application number CN201520385217.9 includes a handle and a head. The front end of the head is a cleaning part, which is a bendable tongue. The shape of the tongue is an isosceles trapezoid that is wider at the front end and narrower at the rear end. The angle of the base angle of the isosceles trapezoid is 70 to 88 degrees. The surface of the cleaning part is covered with a cleaning cloth.

[0005] However, the current method of wiping CCDs with a wiping stick is time-consuming, laborious, and has poor wiping effect, with low automation. Utility Model Content

[0029] Example 1, combined with Figure 1 , Figure 2 and Figure 8 Explanation:

[0030] A CCD wiping mechanism includes: a base 1, an X-motion mechanism 2, a Y-motion mechanism 3, a mounting plate 4, a non-woven fabric drive wheel assembly 5, a non-woven fabric 6, a liquid metering valve 7, a plasma cleaner 8, a wiping head assembly 9, and a floating assembly 10.

The first drive wheel 51 and the second drive wheel 52 are rotatably mounted on the mounting plate 4. The tensioning assembly is located on one side of the transmission belt assembly 54 and works in conjunction with the transmission belt assembly 54. The first drive wheel 51 is used to place new nonwoven fabric 6, and the second drive wheel 52 is used to collect used nonwoven fabric 6.

[0038] With this configuration, the drive motor 53 drives the first drive wheel 51 and the second drive wheel 52 to rotate via the transmission belt assembly 54. The transmission belt assembly 54 includes a drive transmission wheel, a transmission belt, and a driven transmission wheel. The output end of the drive motor 53 drives the drive transmission wheel to rotate via a gear assembly. The drive transmission wheel drives the driven transmission wheel to rotate via the transmission belt, thereby driving the drive transmission wheel and the driven transmission wheel to rotate the first drive wheel 51 and the second drive wheel 52. The tensioning assembly 55 is used to adjust the tension of the transmission belt. The tensioning assembly 55 is existing technology and will not be described in detail here.

[0039] The mounting plate 4 is provided with multiple sets of nonwoven fabric rollers 61, which are used in conjunction with the nonwoven fabric 6 to feed the nonwoven fabric 6.

[0040] Example 3, based on Example 2, combined with Figure 6 Explanation:

[0041] The wiping head assembly 9 includes a wiping head 91, a pneumatic finger cylinder 92, and grippers 93. The wiping head 91 is fixedly mounted on the pneumatic finger cylinder 92, which is fixedly mounted on the drive end of the floating assembly 10. Two sets of grippers 93 are provided, and the two sets of grippers 93 are fixedly mounted on the drive end of the pneumatic finger cylinder 92. The two sets of grippers 93 are located on both sides of the wiping head 91. The wiping head 91 is used to support the nonwoven fabric 6.

[0042] The gripper 93 is used to clamp the non-woven fabric 6 during wiping, the wiping head 91 is used to support the non-woven fabric 6, and the pneumatic finger cylinder 92 is used to drive the gripper 93 to clamp the non-woven fabric 6.

[0043] Example 4, based on Example 3, combined with Figure 7 Explanation:

[0044] The floating assembly 10 includes: a floating slide plate 101, a slide base 102, a floating drive plate 103, a guide rod 104, a floating drive sleeve 105, a floating drive rod 106, a floating spring 107, and a floating fixing block 108. The floating slide plate 101 is slidably mounted on the slide base 102, and the slide base 102 is fixedly mounted on one side of the mounting plate 4. One side of the floating drive plate 103 is fixedly connected to the pneumatic finger cylinder 92, and the other side of the floating drive plate 103 is fixedly connected to the floating slide plate 101. The floating slide plate 101 is slidably mounted on the guide rod 104, and the end of the guide rod 104 is fixedly connected to the mounting plate 4. The floating drive sleeve 105 is fixedly connected to the floating drive plate 103. The floating drive rod 106 passes through the floating drive sleeve 105 and is fixedly connected to the floating fixing block 108 fixedly mounted on the other side of the mounting plate 4. The floating spring 107, which is fitted on the floating drive rod 106, is located between the floating drive plate 103 and the floating fixing block 108.

[0045] In use, the floating slide plate 101 can slide along the slide base 102, and the floating drive plate 103 moves together with the floating slide plate 101. The floating drive plate 103 is guided by the guide rod 104. The floating drive sleeve 105 is fitted on the floating drive rod 106 and is slidably connected to the floating drive rod 106. When the CCD surface is high, the floating spring 107 is compressed by the floating slide plate 101 and the floating drive plate 103, thereby ensuring that the CCD height difference is compensated during wiping.

[0046] With this configuration, the floating component 10 ensures that the CCD height difference is compensated during wiping, ensuring that the nonwoven fabric 6 adheres to the CCD with appropriate force.

[0047] The working principle of this utility model is as follows: When using this device, first turn on the plasma cleaner 8 and run it along the upper surface of the CCD to burn off the organic dust on the CCD surface. Then, open the liquid metering valve 7 and drip 1-2 drops of alcohol onto the non-woven fabric 6 to saturate it. The gripper 93 clamps the non-woven fabric 6, and the wiping head 91 supports and holds the non-woven fabric 6. The Y-motion mechanism 3 drives the wiping head assembly 9 to move downward through the mounting plate 4, so that the wiping head 91 is close to the upper surface of the CCD. The X-motion mechanism 2 moves the wiping head 91 to complete the wiping of the CCD. This utility model can wipe the CCD, freeing up manpower and improving wiping efficiency.
