Description

Technical Field

[0001] This application relates to the technical field of dust removal equipment for mobile phone glass covers, specifically to a dust removal device for mobile phone glass covers through adsorption. Background Technology

[0002] During the production of mobile phone glass covers, dust easily adheres to the surface of the glass cover. If not thoroughly removed, it will affect subsequent processes such as lamination and coating, reducing product quality and increasing the defect rate. Currently, various equipment and technologies for dust removal from glass covers are available on the market.

[0003] Patent CN219581254U discloses a surface electrostatic dust removal device that uses a controller, a rotating mechanism, and a dust removal mechanism to remove dust from the surface of a mobile phone cover. However, the device has a relatively complex structure and its design for the coordinated conveying and adsorption of dust on the glass cover is not perfect, making it difficult to meet the needs of efficient and stable large-scale production.

[0004] The patent with publication number CN119926935A proposes a fully automated production system for mobile phone glass covers. It uses a dust-adhesive roller for electrostatic adsorption and a wiping roller for cleaning grease stains. However, the system has shortcomings in the detailed design of electrostatic adsorption, such as the coordination between static electricity generation and adsorption components, as well as the subsequent dust treatment, which leads to the need to improve the dust removal effect and efficiency.

[0005] In existing technologies, some equipment has a low degree of automation and relies heavily on manual operation, which is not only inefficient, but also greatly affected by human factors in dust removal quality. Some equipment, although adopting the principle of electrostatic dust removal, has defects in key aspects such as the coordinated operation of electrostatic generator and adsorption structure and dust collection and treatment, and cannot achieve efficient, stable and thorough dust removal.

[0006] Therefore, there is a need for a mobile phone glass cover adsorption dust removal device with reasonable structural design, high degree of automation, and good dust removal effect to meet the high-quality dust removal requirements in the production process of mobile phone glass covers. Summary of the Invention

[0007] To address the aforementioned technical problems, this application solves the issues of low automation, poor dust removal effect, and difficulty in efficiently and stably removing dust from the surface of the glass cover, which affects the quality of subsequent processing in existing mobile phone glass cover dust removal equipment.

[0008] To achieve the above objectives, the technical solution adopted in this application is as follows: a mobile phone glass cover adsorption dust removal device, comprising a body assembly, an adsorption assembly, an electrostatic generator, and a blower assembly, wherein the adsorption assembly, the electrostatic generator, and the blower assembly are all fixedly installed on the body assembly.

[0009] The adsorption assembly includes a side support frame, a side mounting frame, sprockets, a chain, and adsorption plates.

The two ends of the conveyor line are respectively connected to the electrostatic emission rod and the DC high-voltage power supply. The electrostatic emission rod is rotatably installed on the support rod, and the support rod is fixedly installed on the DC high-voltage power supply.

[0011] The blower assembly includes a protective frame, a rotating shaft, an adsorption rod, and adsorption brushes.

[0012] Preferably, the machine body assembly includes a mounting platform and a conveying mechanism. The mounting platform is used to mount the adsorption assembly, the electrostatic generator, and the blower assembly, and the conveying mechanism is used to convey the glass cover plate.

[0013] Preferably, the adsorption assembly includes a motor and a main shaft. The motor is fixedly mounted on the mounting platform, the main shaft is fixedly connected to the output end of the motor, and the main shaft is fixedly connected to the side mounting bracket at the lowest end.

[0014] Preferably, two electrostatic emission rods are provided, and the distance between the two electrostatic emission rods is greater than 30 centimeters.

[0015] Preferably, the blower assembly includes a blower, a ventilation duct, and a guide cover.

[0016] Preferably, the blower assembly includes a short belt and a long belt, and two rotating shafts are provided on the protective frame. The two rotating shafts are connected by the short belt, and one of the rotating shafts is connected to the power source of the adsorption assembly by the long belt.

[0017] Preferably, the blower assembly includes a grille, which is fixedly installed on the output port of the protective frame. The grille is used to disrupt the adsorption brush, causing dust to fall off the adsorption brush.

[0018] The technical solution provided in this application has the following advantages compared with the prior art:

[0019] 1. This application achieves automation of the dust removal process for mobile phone glass covers through the coordinated operation of the body components, adsorption components, electrostatic generator, and blower components, solving the problems of low efficiency and high labor intensity of manual dust removal and improving production efficiency.

[0020] 2. This application utilizes an electrostatic generator to apply static electricity to the adsorption plate.

[0023] 5.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0033] like Figures 1 to 5 As shown, a mobile phone glass cover adsorption dust removal device includes a body assembly 100, an adsorption assembly 200, an electrostatic generator 300, and a blower assembly 400, wherein the adsorption assembly 200, the electrostatic generator 300, and the blower assembly 400 are all fixedly installed on the body assembly 100.

[0034] Specifically, the glass cover is conveyed by the body assembly 100, moving it to the area where the adsorption assembly 200 is located. Then, the electrostatic generator 300 applies static electricity to the adsorption assembly 200. When a part on the adsorption assembly 200 carrying static electricity approaches the glass cover, the dust on the glass cover is adsorbed by static electricity, achieving the dust removal effect. Then, the part on the adsorption assembly 200 carries the dust into the blower assembly 400. The blower assembly 400 uses airflow to detach the dust from the adsorption assembly 200 and transport it to the outside for collection. This completes the dust adsorption and removal work on the glass cover.

[0035] like Figure 2As shown, the adsorption assembly 200 includes a side support frame 203, a side mounting frame 204, sprockets 205, a chain 206, and adsorption plates 207. The side mounting frame 204 is provided with multiple side support frames 203, which are mounted on the body assembly 100. The side mounting frame 204 is provided with three sprockets 205 arranged in a triangle. The three sprockets 205 are connected to a chain 206, and multiple adsorption plates 207 are fixedly mounted on the chain 206.

[0036] Specifically, multiple adsorption plates 207 are supported and driven by chains 206 on both sides, and the chains 206 are supported and driven by sprockets 205 on the side mounting brackets 204 on both sides, thereby enabling the adsorption plates 207 to move cyclically along the inverted triangular trajectory formed by the three sprockets 205, such as... Figure 4 As shown, the upper end of the inverted triangular trajectory is horizontal, and the lower end is the apex of the triangle. When the adsorption plate 207 moves to the right at the upper end of the trajectory, it passes the electrostatic generator 300. The electrostatic generator 300 applies a charge to the adsorption plate 207, causing it to generate an electrostatic effect. Then, when the electrostatically charged adsorption plate 207 moves to the lowermost apex of the inverted triangle, the adsorption plate 207 is closest to the glass cover at this point. The electrostatic charge on the adsorption plate 207 adsorbs and removes dust from the glass cover, causing the dust to adhere to the adsorption plate 207. Then, the adsorption plate 207 continues to move along the trajectory and enters the blower assembly 400. The blower assembly 400 removes the dust from the adsorption plate 207, allowing it to be transported to the outside for collection with the flow of gas.

[0037] like Figure 2 As shown, the electrostatic generator 300 includes a DC high-voltage power supply 301, a conveyor line 302, a support rod 303, and an electrostatic emission rod 304. The DC high-voltage power supply 301 is fixedly installed on the body assembly 100. The two ends of the conveyor line 302 are respectively connected to the electrostatic emission rod 304 and the DC high-voltage power supply 301. The electrostatic emission rod 304 is rotatably installed on the support rod 303, and the support rod 303 is fixedly installed on the DC high-voltage power supply 301.

[0038] Specifically, a high-voltage current is provided by a DC high-voltage power supply 301 and delivered to an electrostatic emitting rod 304 via a conveyor line 302. This causes the electrostatic emitting rod 304 to emit ions, thereby charging the parts that pass through the electrostatic emitting rod 304 for subsequent adsorption and dust removal.

[0039] like Figure 3As shown, the blower assembly 400 includes a protective frame 404, a rotating shaft 405, an adsorption rod 406, and adsorption brushes 407. The protective frame 404 is fixedly installed on the body assembly 100. Multiple adsorption brushes 407 are provided on the adsorption rod 406. The adsorption rod 406 is fixedly installed on the rotating shaft 405, and the rotating shaft 405 is rotatably installed on the protective frame 404.

[0040] Specifically, the rotating shaft 405 on the blower assembly 400 drives the adsorption rod 406 and the adsorption brush 407 to rotate around the axis of the rotating shaft 405. The adsorption brush 407 then contacts the adsorption plate 207 and uses the fibers on the adsorption plate 207 to adsorb dust, causing it to detach from the adsorption plate 207. The brush then rotates upwards, and the airflow causes the dust on the adsorption brush 407 to detach from the adsorption brush 407 and flow with the gas, exiting the protective frame 404. Meanwhile, the adsorption plate 207 continues to move and is charged again for the next electrostatic dust removal.

[0041] like Figure 1 As shown, the body assembly 100 includes a mounting platform 101 and a conveying mechanism 102. The mounting platform 101 is used to mount the adsorption assembly 200, the electrostatic generator 300 and the blower assembly 400, and the conveying mechanism 102 is used to convey the glass cover plate.

[0042] Specifically, the power source, motors 201 and 310, and blower 401 of the conveying mechanism 102 are installed on the mounting platform 101. The glass cover is conveyed by the conveying mechanism 102, so that the outer side of the protective frame 404 moves to the bottom of the protective frame 404, then to the bottom of the main shaft 202, and finally out.

[0043] like Figure 2 As shown, the adsorption assembly 200 includes a motor 201 and a main shaft 202. The motor 201 is fixedly mounted on the mounting platform 101, the main shaft 202 is fixedly connected to the output end of the motor 201, and the main shaft 202 is fixedly connected to the side mounting bracket 204 at the lowest end.

[0044] Specifically, the motor 201 generates power, and the motor 201 drives the bottom sprocket 205 to rotate through the main shaft 202. Then, the sprocket 205 drives the other two sprockets 205 to rotate through the chain 206. In turn, the chain 206 drives multiple adsorption plates 207 to move along an inverted triangular trajectory, so that the multiple adsorption plates 207 gradually move to the bottom tip to remove dust from the glass cover.

[0045] like Figures 2 to 4 As shown, there are two electrostatic emission rods 304, and the distance between the two electrostatic emission rods 304 is greater than 30 cm.

[0046] The electrostatic emitting rod 304 generates ions through tip discharge, creating a stable electric field around it. If the two electrostatic emitting rods 304 are too close together, their electric fields will overlap, causing a sudden increase in local electric field strength. This excessively strong local electric field may disrupt the charge distribution on the surface of the adsorption plate 207, affecting the electrostatic treatment effect, such as reducing the firmness of electrostatic adsorption.

[0047] like Figure 2 As shown, the blower assembly 400 includes a blower 401, a ventilation duct 402, and a guide cover 403. The blower 401 is fixedly installed on the mounting platform 101. The input end of the blower 401 is fixedly connected to the ventilation duct 402. The protective frame 404 is fixedly installed on the conveying mechanism 102 and the ventilation duct 402. The input port of the ventilation duct 402 is fixedly connected to the output port of the guide cover 403. The guide cover 403 is fixedly connected to the top end of the protective frame 404.

[0048] Specifically, the protective frame 404, guide cover 403, ventilation duct 402 and blower 401 form a gas flow channel. When the blower 401 is started, the blower 401 drives the gas to flow in the above channel, thereby realizing the discharge and collection of gas and dust in the protective frame 404. That is, the wind force generated by the blower 401 is used to drive the dust on the adsorption plate 207 to fall off and move away from the adsorption plate 207.

[0049] like Figure 2 As shown, the blower assembly 400 includes a short belt 409 and a long belt 410. Two rotating shafts 405 are provided on the protective frame 404. The two rotating shafts 405 are connected by the short belt 409. One of the rotating shafts 405 is connected to the power source of the adsorption assembly 200 through the long belt 410.

[0050] Specifically, when the main shaft 202 is driven by the motor 201, the main shaft 202 drives a rotating shaft 405 to rotate on the protective frame 404 via a long belt 410. The rotating shaft 405 drives another rotating shaft 405 to rotate synchronously via a short belt 409. Consequently, the adsorption rods 406 and adsorption brushes 407 on the two rotating shafts 405 also rotate, causing multiple adsorption brushes 407 to gradually contact the adsorption plate 207 and drive the dust off the adsorption plate 207.

[0051] like Figure 5 As shown, the blower assembly 400 includes a grille 408, which is fixedly installed on the output port of the protective frame 404. The grille 408 is used to disrupt the adsorption brush 407, so that dust falls off the adsorption brush 407.

[0052] Specifically, after the adsorption brush 407 removes the dust from the adsorption plate 207, it rotates to the upper part. Through contact with the grid 408, some of the fibers of the adsorption brush 407 are blocked, thereby increasing the gap between the fibers. At this time, when the gas flows, it is easier to carry the dust away from the adsorption brush 407.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
