Description

Technical Field

[0001] The invention relates to the technical field of capacitive touch screen production, and in particular to a raw material cleaning device for capacitive touch screen processing. Background Art

[0002] The basic structure of a capacitive touch screen is: the substrate is a single layer of organic glass, a transparent conductive film is evenly forged on the inner and outer surfaces of the organic glass, and then a narrow electrode is tapered on the four corners of the transparent conductive film on the outer surface. Organic glass is one of the important raw materials for the production of capacitive touch screens. Before entering the production process of capacitive touch screens, the organic glass needs to be cleaned to remove impurities attached to the surface of the organic glass.

[0003] At present, the cleaning process of organic glass is mainly carried out automatically by cleaning equipment. The cleaning equipment uses a spray device and a roller brush to clean the organic glass, and then blows or dries the organic glass. However, most of the existing cleaning equipment uses a conveyor roller to transport the organic glass, and the conveyor roller drives the organic glass by friction. During the cleaning process, the roller brush uses a brush or the rotation direction of the roller brush needs to be consistent with the conveying direction of the organic glass, otherwise the force between the roller brush and the organic glass will hinder the conveying of the organic glass, resulting in a decrease in conveying efficiency and ultimately a decrease in cleaning efficiency. The roller brush rotates in the same direction, so the contact area between the organic glass and the roller brush is small, and the cleaning effect is poor. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments; the technical features designed in different implementation modes of the present invention described below can be combined with each other as long as they do not conflict with each other; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be noted that all terms (including technical terms and scientific terms) used in the present invention have the same meanings as those generally understood by ordinary technicians in the field to which the present invention belongs, and should not be understood as limitations on the present invention; it should be further understood that the terms used in the present invention should be understood to have the same meanings as these terms in the context of this specification and in the relevant fields, and should not be understood in an idealized or overly formal sense, unless explicitly defined in this invention.

[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0023] Please refer to Figures 1 to 12 A device for cleaning raw materials for processing capacitive touch screens is used to clean raw materials for processing capacitive touch screens, including: a frame 1, a conveying module 2, a spraying and brushing module 5 and a driving module 3.

[0024] The frame 1 is distributed along the first direction and has a cubic structure as a whole, and has a working cavity 11 inside. The conveying module 2, the spraying and brushing module 5 and the driving module 3 are arranged in the working cavity 11. Specifically, the first direction is the length direction of the frame 1, and the second direction is the width direction of the frame 1.

[0025] The conveying module 2 is distributed along the width direction of the frame 1. The conveying module 2 includes a conveying roller group 22 and a transfer roller group 21. The transfer roller group 21 is arranged at the front and rear ends of the upper and lower roller brush groups 51, and the conveying roller group 22 is arranged at the front end or the rear end of the transfer roller group 21; the driving module 3 is connected to the conveying module 2 by driving. Specifically, the conveying roller group 22 can adopt a solution of a central rotating rod cooperating with a turntable. Specifically, the driving module 3 includes a driving motor 31 and a screw 32. The driving motor 31 drives the screw 32 to rotate, thereby driving the worm gear 33 on the screw 32 to transmit with the worm 34 arranged at the driving end of the conveying roller group 22 and the transfer roller group 21. Those skilled in the art can select a suitable driving module 3 and a conveying roller group 22 according to needs, without specific restrictions.

[0026] The spray brush module 5 includes an upper and lower roller brush group 51 and a spray pipe group 52. The upper and lower roller brush group 51 is arranged in the working cavity 11. The rotation direction of the upper and lower roller brush group 51 is opposite to the conveying direction of the conveying module 2. The spray pipe group 52 is at least arranged at the front end of the upper and lower roller brush group 51. Specifically, the upper and lower roller brush group 51 includes an upper roller brush 511 and a lower roller brush 512. The upper roller brush 511 rotates in opposite directions to the lower roller brush 512, so that the upper and lower roller brush groups 51 can clean the upper and lower surfaces of the raw material in the same direction respectively. At the same time, the rotation direction of the upper and lower roller brush groups 51 is opposite to the conveying direction of the conveying module 2, that is, the rotation direction of the lower roller brush is opposite to the conveying roller group 22 and the transfer roller group 21 in the conveying module 2. The upper and lower roller brush groups 51 are driven separately or together by the roller brush motor 513. Specifically, the spray pipe group 52 is arranged before the upper and lower roller brush groups 51, so that the raw material contacts the upper and lower roller brush groups 51 after being sprayed. The upper and lower roller brush groups 51 can be round rollers with surfaces covered with non-woven fabrics, sponges, etc., or conventional brush rollers. Technical personnel in this field can adjust the spacing, position, and type of the spray pipe group 52 and the upper and lower roller brush groups 51 as needed without specific limitation.

[0027] The conveying module 2 includes a conveying roller group 22 and a transfer roller group 21. The transfer roller group 21 is arranged at the front and rear ends of the upper and lower roller brush groups 51, and the conveying roller group 22 is arranged at the front end or the rear end of the transfer roller group 21; the transfer roller group 21 includes a transfer roller body 211, a driving end cover 212, a driven end cover 213 and a central component. The driving end cover 212 and the driven end cover 213 are respectively arranged at the two ends of the transfer roller body 211, and the driving end cover 212 drives the transfer roller body 211 to rotate.

[0028] The two ends of the central component are rotatably connected to the driving end cover 212 and the driven end cover 213 respectively; the transfer roller body 211 has a transfer cavity 218 inside, and the surface of the transfer roller body 211 is provided with first through holes 2111 arranged in an array, and the transfer roller body 211 has a transfer cavity 218 inside, and the transfer cavity 218 is connected with the outer side of the transfer roller body 211 through the first through hole 2111; the transfer cavity 218 is divided by the central component into an adsorption chamber 2181 and a blowing chamber 2182 which are stationary relative to the frame 1; the adsorption chamber 2181 and the purge chamber are connected with the adsorption air path 13 and the purge air path 14; on the conveying path of the raw material, the raw material is firstly adsorbed by the adsorption chamber 2181 to enhance the lateral conveying effect, and then supported by the blowing chamber 2182.

[0029] Specifically, the adsorption chamber 2181 is arranged on the side close to the direction of the raw material, and the contact point between the transfer roller body 211 and the raw material can be connected to the projection area of ​​the adsorption chamber 2181 through the first through hole 2111, so that the raw material can be adsorbed by the transfer roller body 211, and is moved forward by the tangential force in the horizontal direction under the rotation of the transfer roller body 211. The forward-moving raw material moves to the influence range of the blowing chamber 2182, and the blowing chamber 2182 blows air outward through the first through hole 2111, and the airflow sweeps the lower surface of the raw material, so that the raw material is supported.

[0030] Specifically, the cylindrical transfer roller body 211, the driving end cover 212 and the driven end cover 213 are combined to form a transfer cavity 218, and the central component is arranged in the transfer cavity 218, and the central component divides the transfer cavity 218 into an adsorption chamber 2181 and a blowing chamber 2182. The adsorption chamber 2181 is connected to the adsorption gas path 13, and the purge chamber is connected to the purge gas path 14. The adsorption chamber 2181 and the blowing chamber 2182 continuously adsorb or support the raw material through the first through hole 2111 on the transfer roller body 211. The operator can adjust the position of the adsorption chamber 2181 and the blowing chamber 2182 by adjusting the angle of the central component, thereby controlling the range and strength of the adsorption or support of the raw material by the transfer roller group 21, which is easy to operate and has strong adjustability. Furthermore, the adsorption chamber 2181 absorbs the lower surface of the raw material, which can absorb the spray liquid adhering to the lower surface of the raw material to a certain extent, thereby preventing the raw material from slipping under the action of the spray liquid and enhancing the conveying effect. At the same time, after the adsorption chamber 2181 absorbs, it can prevent the formation of a liquid film on the lower surface of the raw material, so that the lower surface of the raw material can preferentially contact the newly sprayed spray liquid.

[0031] The limiting modules 4 are arranged on both sides above the transfer roller group 21, and are used to lift the offset raw materials and move them to the set positions at the same time.

[0032] It can be understood that the transfer roller group 21 of the raw material cleaning device for capacitive touch screen processing provided by the present invention is through a central component that can rotate freely relative to the transfer roller body 211. When the transfer roller body 211 is driven to rotate, an adsorption chamber 2181 and a blowing chamber 2182 with stable positions are formed inside the transfer roller body 211, so that the conveying path forms a vacuum adsorption area and a blowing support area. The force of the transfer roller group 21 on the raw material is enhanced through different areas, so that the raw material can overcome the force of the upper and lower roller brush groups 51 whose rotation direction is opposite to the conveying direction, and then the upper and lower roller brush groups 51 can fully wipe the upper and lower surfaces of the raw material, thereby enhancing the cleaning effect while ensuring stable transportation.

[0033] Preferably, the raw material cleaning device for capacitive touch screen processing can be equipped with multiple groups of spraying and brushing modules 5 and conveying modules 2 as needed to form different cleaning sections. Those skilled in the art can adjust the type of liquid sprayed in different cleaning sections as needed without specific limitation.

[0034] Preferably, it also includes an air knife assembly 12, which is arranged in the working cavity 11 and located at the upper and lower sides of the conveying roller group 22. The air knife assembly 12 can be arranged at the rear end of the spray brushing module 5 to blow and dry the cleaned raw materials, thereby improving the cleaning effect and improving the overall cleaning process.

[0035] Preferably, a partition plate is further included, which is arranged on the frame 1 and separates the driving module 3 from the conveying module 2 and the spraying and brushing module 5. The partition plate prevents the driving module 3 from being affected by the spraying liquid in the spraying and brushing module 5, reduces the occurrence of rust, and increases the service life of the driving module 3.

[0036] More preferably, it further includes a liquid supply module and a filtering and converging module, wherein the liquid supply module is arranged on the frame 1, and the liquid supply module is connected with the spraying and brushing module 5 to supply liquid to the spraying pipe group 52. The filtering and converging module is arranged below the spraying and brushing module 5, and the cleaned liquid is filtered and then pumped to the liquid supply module for recycling, thereby reducing costs and waste of resources.

[0037] In one embodiment, the central assembly includes a first bearing 214, a second bearing 215, a central rod 216, and at least two cavity adjustment plates 217. The cavity adjustment plates 217 are distributed along the second direction and arranged on the central rod 216. The cavity adjustment plates 217 abut against the inner wall of the transfer roller body 211. Specifically, both ends of the central rod 216 are rotatably connected to the driving end cover 212 and the driven end cover 213 through the first bearing 214. The cavity adjustment plates 217 are distributed along the second direction and arranged on the central rod 216. The cavity adjustment plates 217 abut against the inner wall of the transfer roller body 211. The cavity adjustment plates 217 separate the transfer cavity 218 into an adsorption chamber 2181 and a blowing chamber 2182.

[0038] In one embodiment, the driving end cover 212 is drivingly connected to the driving module 3; the driven end cover 213 has a hollow extension end 2131, and the hollow extension end 2131 is provided with a second bearing 215, and the second bearing 215 is connected to the frame 1; the end of the center rod 216 close to the driven end cover 213 extends from the hollow extension end 2131 to the outside of the driven end cover 213 and is connected to the frame 1. Specifically, the driving end cover 212 is a disc structure as a whole, and the driving end cover 212 is sealed and connected to the transfer roller body 211, and drives the transfer roller body 211 to rotate. A connecting groove is provided in the center of one side of the driving end cover 212 close to the center rod 216, and the first bearing 214 is arranged in the connecting groove. The side of the driving end cover 212 away from the center rod 216 is drivingly connected to the driving module 3. Specifically, the driven end cover 213 is a funnel-shaped structure with a hollow extension end 2131 in the middle, a second bearing 215 is sleeved outside the hollow extension end 2131, and a connecting channel is formed inside the hollow extension end 2131, the connecting channel ensures that the transfer roller body 211 can rotate normally, and does not affect the connection between the center rod 216 and the frame 1. And the connecting channel enables the adsorption gas path 13 and the purge gas path 14 to communicate with the transfer cavity 218.

[0039] In one embodiment, a support plate 2161 is provided between the center rod 216 and the first bearing 214, and the support plate 2161 abuts against the cavity adjustment plate 217. After the support plate 2161 is provided, the gap between the center rod 216 and the first bearing 214 can be closed, and the overall air tightness can be improved, thereby improving the adsorption and purging effects. At the same time, the support plate 2161 supports the center rod 216, so that the center rod 216 is located on the axis of the transfer roller body 211.

[0040] Preferably, at least two second through holes 2162 are provided on the support plate 2161, and the second through holes 2162 are located between the cavity adjustment plates 217. The adsorption gas path 13 and the purge gas path 14 are connected to the adsorption chamber 2181 or the purge chamber 2182 through the second through holes 2162. Specifically, the second through holes 2162 are provided on the support plate 2161 located on one side of the driven end cover 213, and the operator can connect the gas path to different second through holes 2162 as needed, which improves the air tightness and functionality, and facilitates the operator to install the adsorption gas path 13 and the purge gas path 14, effectively reducing the difficulty of maintenance.

[0041] In one embodiment, an arc-shaped extension portion 2171 is provided at one end of the cavity adjustment plate 217 abutting against the inner wall of the transfer roller body 211, and the arc-shaped extension portion 2171 is in contact with the inner wall of the transfer roller body 211. Specifically, after the arc-shaped extension portion 2171 is provided, the contact area between the cavity adjustment plate 217 and the inner wall of the transfer roller body 211 can be expanded, the sealing between different chambers can be enhanced, and the adsorption and purging effects can be strengthened.

[0042] In one embodiment, support ring plates 2172 are arranged between the arc-shaped extensions 2171, and the support ring plates 2172 are in contact with the inner wall of the transfer roller body 211. After the support ring plates 2172 are arranged, they can support the cavity adjustment plates 217, ensure that the angles and positions between the cavity adjustment plates 217 do not change, and improve the stability of the overall structure without affecting the adsorption or supporting effect. Specifically, the length of the support ring plates 2172 can be adjusted by those skilled in the art according to the distance between the arc-shaped extensions 2171, and is not specifically limited.

[0043] In one embodiment, the surface of the transfer roller body 211 is coated with a rubber layer 219. The rubber layer 219 generates elastic deformation after contacting the raw material, so that the line contact between the transfer roller body 211 and the raw material is expanded to surface contact, which can enhance the tangential force of the transfer roller body 211 on the raw material. At the same time, the rubber layer 219 can provide a partial buffering effect on the raw material, avoiding rigid contact between the raw material and the transfer roller body 211, ensuring that the raw material is not scratched during the conveying process, thereby ensuring the yield rate.

[0044] In one embodiment, three cavity adjustment plates 217 are provided, and / or the cavity adjustment plates 217 are hinged to the central rod 216. Specifically, the three cavity adjustment plates 217 divide the transfer cavity 218 into three chambers, of which two chambers close to the upper side are adsorption chambers 2181 and blowing chambers 2182, and the chamber on the lower side is an adjustment chamber 2183. The cavity adjustment plates 217 are connected to the central rod 216 in a hinged form, so that the operator can adjust the size of the adsorption chamber 2181 or the blowing chamber 2182 by rotating the cavity adjustment plates 217 at different positions, thereby adjusting the scope and effect of different areas. Specifically, the cavity adjustment plate 217 and the center rod 216 may adopt a hinge structure. The hinge structure may be a manner of hingedly connecting a bracket rod to the center rod 216, and arranging the cavity adjustment plate 217 between the bracket rods. Those skilled in the art may select a suitable hinge structure so that the cavity adjustment plate 217 can rotate relative to the center rod 216 without specific limitation.

[0045] Preferably, the size of the blowing chamber 2182 is 60° to 90°, the size of the adsorption chamber 2181 is 90° to 150°, and the blowing chamber 2182 is horizontally arranged away from the cavity adjustment plate 217 of the adsorption chamber 2181. This arrangement can avoid wasting airflow in the lower area that does not affect the raw materials on the basis of ensuring the adsorption effect and the supporting effect, thereby reducing the production cost.

[0046] In one embodiment, the limiting module 4 includes a limiting plate 41 and a fixing rod 42, one end of the fixing rod 42 is arranged on the frame 1, and the other end of the fixing rod 42 is connected to the limiting plate 41; the limiting plate 41 includes a straight plate portion 411 and an inclined plate portion 412, the plane where the straight plate portion 411 is located is perpendicular to the plane where the raw material is located, and the inclined plate portion 412 is inclined from the edge of the straight plate portion 411 toward the direction of the raw material, and the bottom surfaces of the straight plate portion 411 and the inclined plate portion 412 are flush with the highest point of the transfer roller body 211; a conical portion 413 is provided at the bottom of the side of the straight plate portion 411 close to the raw material, and the conical portion 413 is in the shape of a quarter cone; a descending portion 414 is provided at the bottom of the side of the inclined plate portion 412 close to the raw material, and the descending portion 414 extends obliquely from the side edge of the conical portion 413 along the surface of the inclined plate portion 412 to the innermost point of the inclined plate portion 412. Specifically, the descending portion 414 is a triangular pyramid structure as a whole, the innermost point of the inclined plate portion 412 is the bottom end point of the inclined plate portion 412 away from the straight plate portion 411, and the distance between the innermost points of the two inclined plate portions 412 is the width of the raw material. This arrangement allows the raw material to be located exactly between the two inclined plate portions 412 after adjustment, thereby limiting the position of the raw material. That is, the limiting plate 41 guides the edge of the raw material to be slightly lifted through the curved surface of the conical portion 413, and the adsorption effect between the raw material and the transfer roller group 21 after the edge is lifted is greatly reduced, so that the raw material that has not reached the set position can overcome the suction force and displace after touching the inclined plate portion 412, and move to the set position along the inclined inclined plate portion 412 as the raw material moves forward. During the movement, the raw material gradually descends along the descending portion 414 until the bottom of the raw material is flush with the highest point of the transfer roller body 211 when it reaches the set position, ensuring the overall level of the raw material and not affecting the subsequent conveying process. Specifically, those skilled in the art can adjust the height of the conical portion 413, the inclination angle and length of the inclined plate portion 412 according to the specifications of the raw material, without specific limitation.

[0047] In one embodiment, at least two transfer roller groups 21 are respectively arranged at the front and rear ends of the upper and lower roller brush groups 51, and the position limiting module 4 is arranged between the highest points of the adjacent transfer roller groups 21. In this arrangement, the tapered portion 413 and the descending portion 414 of the position limiting module 4 can support the raw material between the maximum adsorption points of the two transfer roller groups 21, so that the raw material adjusted to the set position can quickly fit with the fitting transfer roller group 21, thereby ensuring the cleaning effect.

[0048] In one embodiment, the fixing rod 42 is a telescopic rod, so that the operator can adjust the position of the limiting module 4 to adapt to raw materials of different specifications.

The arc-shaped extension part 2171 is in contact with the inner wall of the transfer roller body 211. A support ring plate 2172 is provided between the arc-shaped extension parts 2171.

[0052] In this embodiment, three cavity adjustment plates 217 are provided, and the cavity adjustment plates 217 are hinged to the central rod 216. The size of the blowing chamber 2182 is 70 degrees, the size of the adsorption chamber 2181 is 140 degrees, and the cavity adjustment plates 217 of the blowing chamber 2182 and the adsorption chamber 2181 are arranged horizontally.

[0053] In this embodiment, the fixing rod 42 is a telescopic rod.

[0054] The working principle of the present invention is as follows: before use, the operator adjusts the cavity adjustment plate 217 to a specified angle, connects the adsorption gas path 13 and the purge gas path 14, and then adjusts the fixing rod 42 to move the limit plate 41 to the set position. Adjust the spacing between the upper and lower roller brush groups 51 and the type of spray liquid of the spray pipe group 52. After the adjustment is completed, the raw material is transported by the conveying roller group 22. The raw material is transmitted to the transfer roller group 21, and is closely attached to the surface of the transfer roller body 211 by the adsorption effect of the adsorption chamber 2181. It moves forward with the rotation of the transfer roller body 211 and is supported by the air flow blown out by the blowing chamber 2182. During the process, the raw material is sprayed by the liquid of the spray pipe group 52. The raw material after spraying continues to move forward, overcomes the force of the upper and lower roller brush groups 51 rotating in the opposite direction, and is received by the next group of transfer roller groups 21. The raw material as a whole is brushed by the upper and lower roller brush groups 51 to remove impurities and is transported to the subsequent section, and the cleaning is completed. When the raw material is offset during the conveying process, the curved surface of the conical portion 413 guides the edge of the raw material to rise a little. After the edge is lifted, the adsorption effect between the raw material and the transfer roller group 21 is greatly reduced, so that the raw material that has not reached the set position can overcome the suction force and move after touching the inclined plate portion 412. As the raw material moves forward, it moves to the set position along the inclined inclined plate portion 412, ensuring that the raw material is cleaned by the upper and lower roller brush groups 51 along the set position.
