Description

Technical Field

[0001] This utility model relates to the field of adhesive tape mounting structure technology, and in particular to an adhesive tape mounting structure for a PCB board cleaning device. Background Technology

[0002] In the current PCB, FPC and LCD panel manufacturing industry, the cleaning roller dust removal machine is a common cleaning and dust removal equipment. It uses adhesive paper rollers to adhere to the surface of the PCB board and rotates as the PCB board is conveyed, thereby adsorbing dust and impurities on the surface of the PCB board onto the adhesive paper, thus cleaning the PCB board.

[0003] Existing cleaning and dust removal structures on the market have two main drawbacks when installing adhesive tape rollers. First, the adhesive tape rollers cannot be perfectly coaxially mounted on the adhesive tape mounting shaft, resulting in the adhesive tape rollers not fully adhering to the PCB board surface and affecting the cleaning effect. Second, existing adhesive tape roller end faces are connected to the adhesive tape mounting shaft via rubber sealing rings, but relative rotation occurs between the adhesive tape rollers and the adhesive tape mounting shaft during the cleaning process, leading to poor PCB board cleaning results. Therefore, improvements are necessary. Utility Model Content

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example:

[0022] refer to Figures 1 to 5A PCB board cleaning device adhesive tape mounting structure includes a pull-out sliding base 1. Elastic lifting bases 3 are slidably connected vertically at both ends of the pull-out sliding base 1 based on elastic lifting components 2. A positioning mounting shaft 4 for positioning one end of the adhesive tape roller is rotatably connected in parallel to the elastic lifting base 3 away from the pull-out end. A positioning abutment shaft 6 for abutting the other end of the adhesive tape roller is rotatably connected in parallel to the elastic lifting base 3 near the pull-out end based on elastic pull-out components 5. Positioning boss components 7 for positioning the positioning grooves 74 at both ends of the adhesive tape roller are provided on the positioning mounting shaft 4 and the positioning abutment shaft 6. When installing the adhesive tape roller, the first... First, position one end of the adhesive roller on the positioning mounting shaft 4. Then, pull the positioning abutment shaft 6 outward through the elastic pull-out component 5 to position the adhesive roller. After positioning, release the elastic pull-out component 5 so that the positioning abutment shaft 6 abuts against the adhesive roller, allowing the adhesive roller to be coaxially mounted on the positioning mounting shaft 4 and the positioning abutment shaft 6, ensuring the installation effect of the adhesive roller. At the same time, since the end of the adhesive roller away from the pull-out end is positioned first, and the end of the adhesive roller closer to the pull-out end is positioned later, and the installer is located at the pull-out end, it is convenient to adjust the relative position between the adhesive roller and the positioning abutment rod.

[0023] refer to Figures 1 to 2 Specifically, the elastic lifting assembly 2 includes a vertical lifting guide rail 21 fixedly connected to the pull-out sliding seat 1 along the vertical direction and a vertical lifting slide 22 slidably connected to the vertical lifting guide rail 21 along the vertical direction. The elastic lifting seat 3 is fixedly connected to the vertical lifting slide 22 based on the connecting rod 23. The elastic lifting seat 3 and the pull-out sliding seat 1 are connected based on the vertical return spring 24. When the PCB board moves directly under the adhesive roller, the elastic lifting seat 3 is pressed down, thereby driving the adhesive roller to press down against the PCB board to clean the surface of the PCB board. During the cleaning process, the adhesive roller rotates synchronously with the positioning mounting shaft 4 and the positioning abutment shaft 6. After the cleaning is completed, the elastic lifting seat 3 is no longer pressed down, and the vertical return spring 24 drives the elastic lifting seat 3 to return.

[0024] refer to Figures 3 to 4Specifically, the elastic pull-out assembly 5 includes a sliding sleeve 51 fixedly connected to the elastic lifting seat 3 along the horizontal axis, and a sliding pull rod 52 slidably connected inside the sliding sleeve 51. A horizontal return spring 53 is sleeved and connected to the sliding pull rod 52. A positioning abutment shaft 6 is rotatably connected to the sliding pull rod 52. A pull handle 54 is fixedly connected to the end of the sliding pull rod 52 away from the positioning abutment shaft 6. Several locking pins 55 are fixedly connected to the pull handle 54. The sliding sleeve 51 is provided with locking pins 55, thereby locking the sliding pull rod 52 into a locking groove 56 on the sliding sleeve 51. When one end of the adhesive roller is positioned and installed on the positioning mounting shaft 4, pulling the pull handle 54 of the elastic pull-out assembly 5 outward will drive the sliding pull rod 52 and the positioning abutment shaft 6. Shaft 6 slides outward. Once the relative position between the end of the adhesive roller near the pull-out end and the positioning abutment shaft 6 is determined, the pull-out handle 54 is released, causing the horizontal return spring 53 to drive the sliding pull rod and the positioning abutment shaft 6 to return to the end of the adhesive roller, thus completing the positioning installation between the adhesive roller and the positioning abutment shaft 6. By setting a locking pin 55 on the pull-out handle 54 and opening a locking groove 56 on the sliding sleeve 51, the locking pin 55 is locked in the locking groove 56, thus ensuring that the relative position between the sliding pull rod 52 and the sliding sleeve 51 is fixed, so that the positioning abutment shaft 6 can rotate synchronously with the adhesive roller. At the same time, when the positioning abutment shaft 6 is not positioned with the adhesive roller, the locking pin 55 cannot be fully locked in the locking groove 56, thus ensuring the positioning effect between the positioning abutment shaft 6 and the adhesive roller.

[0025] refer to Figure 2 and Figure 5 Specifically, the positioning boss assembly 7 includes a mounting groove 71 formed on the positioning mounting shaft 4 or the positioning abutment shaft 6, and a mounting plate 72 locked and fixedly connected to the end face of the positioning mounting shaft 4 or the positioning abutment shaft 6. A positioning pin 73 is fixedly connected to the mounting plate 72 and inserted into the mounting groove 71. The positioning pin 73 is inserted into the positioning groove 74 to achieve relative fixation between the adhesive roller and the positioning mounting shaft 4 and the positioning abutment shaft 6, so as to avoid relative rotation between the adhesive roller and the adhesive mounting shaft during the cleaning process, which would affect the cleaning effect of the PCB board. At the same time, different specifications of mounting plates 72 and positioning pins 73 can be replaced to adapt to the positioning and fixing requirements of different specifications of adhesive rollers. A sealing groove 8 for fitting a sealing gasket is coaxially formed on the positioning mounting shaft 4 and the positioning abutment shaft 6 to further ensure the connection effect between the adhesive roller and the positioning mounting shaft 4 and the positioning abutment shaft 6.

[0026] Brief description of the usage process: First, position the end of the adhesive roller furthest from the pull-out end on the positioning mounting shaft 4. Then, pull the pull handle 54 of the elastic pull-out assembly 5 outward, thereby causing the sliding pull rod 52 and the positioning abutment shaft 6 to slide outward. After the relative position between the end of the adhesive roller closest to the pull-out end and the positioning abutment shaft 6 is determined, release the pull handle 54 so that the horizontal return spring 53 drives the sliding pull rod and the positioning abutment shaft 6 to return to the end of the adhesive roller, thereby completing the installation of the adhesive roller.
