[0002] In the PCB industry, due to the difficulty in recruiting workers, the demand for automation is getting higher and higher. Drilling equipment is an indispensable link, and the demand for its automation is constantly increasing.

[0003] During the spindle drilling process, dust will be generated and enter the spindle clamping part (chuck), causing the spindle to have a series of processing problems such as increased runout after the spindle clamps the drill needle, resulting in needle breakage or increased drilling diameter. Currently, the chuck cleaning assembly is used to clean the spindle chuck synchronously on all 6 axes at a time.

[0004] However, the current solutions for cleaning the chuck are all semi-automatic structures, which require human participation. The dust cover of the cleaning chuck assembly must be manually removed to achieve the function of cleaning the chuck. The role of the dust cover of the cleaning chuck assembly is that dust will be generated during the drilling process, and the dust will contaminate the cleaning tool, resulting in secondary contamination of the spindle chuck during the cleaning process. Therefore, the dust cover is indispensable. However, the dust cover on the market is currently removed manually, which requires human participation and cannot be fully automated, which hinders the degree of automation. Utility Model Content

Preferably, in the present embodiment, the grabbing rod 122 is configured as a cylindrical structure. In order to improve the grabbing stability of the grabbing rod 122, a number of friction features may be provided on the outside of the grabbing rod 122, such as anti-slip protrusions, such as rubber protrusions, etc., so as to improve the stability of grabbing and moving when the clamping mechanism 2 is in the process of clamping the grabbing rod 122, and avoid the problem of the dust cover 11 falling off.

[0050] Reference Figure 2In some embodiments, the cleaning mechanism 1 in the utility model includes a lifting assembly 13 and a carrying box 14, and the lifting assembly 13 is used to drive the carrying box 14 to move along the second direction. Preferably, in this embodiment, the lifting assembly 13 can be directly driven by a cylinder, an electric push rod, a hydraulic cylinder, etc., or a motor can be used to drive the sprocket chain to rotate, and the mechanical structure design of the chain driving the displacement is adopted. The above means are technical solutions that can be set up by technicians in the relevant field without any technical obstacles, and will not be described in detail here.

In addition, in the present embodiment, the first direction is the same as the second direction. Secondly, in the present embodiment, "first", "second", etc. are only used to distinguish each other, rather than to indicate the degree of importance and order, and the premise of mutual existence.

[0052] Reference Figure 2 The carrier box 14 has a receiving port 141, in which an oil spray assembly 15 and a brush assembly 16 are installed. Specifically, the oil spray assembly 15 is used to connect with an external oil supply device to spray oil and flush the inside of the chuck, and the brush assembly 16 is used to contact and clean the inner cavity of the chuck, thereby ensuring the cleanliness of the inside of the chuck;

[0061] 3)Reference Figure 8 , the driving component 21 controls the clamping component 22 to lift, and the dust cover 11 completes the automatic cover withdrawal function;

[0062] 4) After the equipment performs the oil spray cleaning function and the brush rotation function, it can realize the automatic capping action, as shown in step 5:

[0063] 5) The driving component 21 controls the clamping component 22 to descend, and the clamping component 22 opens. The driving component 21 controls the clamping component 22 to lift, and the automatic capping action is completed.
