Description

Technical Field

[0001] This utility model relates to cleaning equipment, and in particular to a dust removal mechanism based on a sticky wheel. Background Technology

[0002] The adhesive roller dust removal mechanism primarily uses an adhesive roller to adsorb and remove foreign objects from the product, transferring them to a more adhesive adhesive paper. Adhesive roller dust removal mechanisms are commonly used in various fields of the 3C electronics industry. Currently, the main problems with dust removal mechanisms in the industry are as follows:

[0003] 1) The cleaning was not thorough, and some small particles of dust could not be removed;

[0004] 2) It cannot automatically feed and receive materials, the adhesive paper has low utilization efficiency and is difficult to adjust;

[0005] 3) Long material changeover time affects production efficiency. Summary of the Invention

[0006] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a dust removal mechanism based on a sticky wheel.

[0007] The objective of this utility model is achieved through the following technical solution: a dust removal mechanism based on a sticky roller, comprising a mounting plate, on the front of which are provided a take-up roller, a feed roller, two transition rollers, a gravity rod, and a pressure adjustment component. The pressure adjustment component adjusts the vertical position of the pressure roller and the sticky roller, and the sticky paper passes between the pressure roller and the sticky roller, cleaning the sticky roller. The gravity rod is located between the two transition rollers and can move up and down according to the different tension of the sticky paper.

[0008] As an improvement of the dust removal mechanism based on the sticky roller of this utility model, the gravity rod is mounted on a slider, the slider is slidably connected to the first slide rail, and two counting sensors are also provided on the front of the mounting plate. The two counting sensors are located on the side of the gravity rod, and the number of times the gravity rod moves up and down is used to monitor the number of times the sticky paper is used.

[0009] As an improvement of the dust removal mechanism based on the sticky roller of this utility model, the back of the mounting plate is provided with a torque motor for controlling the forward and reverse rotation of the feeding drum and a stepper motor for controlling the receiving drum to collect the material.

[0010] In standby mode, the torque motor provides a pulling force F1 to the adhesive paper that is greater than the gravity F3 of the gravity rod, and the gravity rod is in the initial position of adhesive application.

[0011] When the adhesive roller comes into contact with the product, it provides an adhesive force F2. The adhesive force F2 plus the gravity F3 of the gravity rod is greater than the pulling force F1, and the gravity rod descends until the adhesive is complete.

[0012] When the sticky roller separates from the product, the adhesive force F2 disappears, and the torque motor provides a pulling force F1 on the sticky paper that is greater than the gravity F3 of the gravity rod, causing the gravity rod to rise to the starting position of the sticky paper.

[0013] As an improvement to the dust removal mechanism based on the sticky roller of this utility model, the counting sensor counts once when the sticky roller completes one dust-sticking cycle. Every time a set number of cycles is reached, the stepper motor controls the take-up drum to wind up. When the take-up drum has wound up the set number of cycles, the sticky paper is replaced. The winding motor winds up every 150 cycles to ensure that the sticky paper is used no more than 150 times. A dust-sticking start sensor counts, and a low-material warning is issued on the 55th count, reminding manual replacement.

[0014] As an improvement to the dust removal mechanism based on the adhesive roller of this utility model, the pressure film adjustment component includes an adjustment mounting plate and an adjustment screw. The adjustment mounting plate is connected to the mounting plate via a slide rail and a slider. The adjustment screw is mounted on a screw seat, which is mounted on the mounting plate. One end of the adjustment screw is connected to a pressure sensor, which is connected to a connecting block. Spring mounting screws are respectively provided at both ends of the connecting block, and springs are fitted onto the spring mounting screws. One end of each spring mounting screw is connected to the adjustment mounting plate. The pressure film adjustment component can adjust the pressure of the adhesive roller on the product. The pressure sensor provides feedback on the downward pressure during product cleaning, protecting the product.

[0015] As an improvement of the dust removal mechanism based on the sticky roller of this utility model, both the pressure roller and the sticky roller are mounted on the adjustment mounting plate. The pressure roller is located above the sticky roller. There are two pressure rollers, which are arranged side by side with a gap on the adjustment mounting plate. There are also two sticky rollers, which are arranged side by side with a gap on the adjustment mounting plate.

[0016] As an improvement to the dust removal mechanism based on the adhesive roller of this utility model, the surface of the pressing roller is serrated. The surface of the pressing roller is treated with a serrated surface and a non-stick coating to reduce the friction between the adhesive paper and the pressing roller and prevent the adhesive paper from sticking to the pressing roller.

[0017] As an improvement of the dust removal mechanism based on the sticky roller of this utility model, the output shaft of the stepper motor is provided with a first synchronous pulley, and one end of the take-up drum is provided with a second synchronous pulley. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt.

[0018] The beneficial effects of this utility model are as follows: This utility model can be widely used in 3C automated cleaning and packaging equipment, greatly improving the cleaning effect of products, enabling automatic material feeding and receiving, convenient and quick material replacement, and improving production efficiency. This utility model also has the following advantages:
