Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a dust cover and film removal equipment. Background Art

[0002] During the glass processing process, the glass needs to be de-filmed to prevent the film from being corroded and oxidized, which will affect the performance and overall quality of the glass.

[0003] In the related art, a grinding wheel and a vacuum cleaner are used to remove film from the glass, so that impurities generated during the film removal can be removed. However, since the grinding wheel for film removal is a consumable grinding wheel, the diameter of the grinding wheel will gradually decrease during use. Therefore, a conventional grinding wheel shield is kept at a certain distance from the glass surface to ensure that the shield does not come into contact with the glass when the diameter of the grinding wheel decreases. However, when the diameter of the grinding wheel is large, since the shield is far away from the glass, particles and dust generated by the grinding wheel during operation will fly, causing a large number of scratches on the glass surface. In addition, the contact surface between the shield and the air is large, which cannot form a good dust collection environment. Utility Model Content

Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0038] The following describes the dust cover 100 of the first embodiment of the present invention with reference to the accompanying drawings. It should be noted that in the accompanying drawings, the up-down direction is shown as the first direction, the front-back direction is shown as the second direction, and the left-right direction is shown as the third direction. The present invention provides a dust cover 100 for glass film removal operations, see FIG. Figures 1 to 5 As shown, the dust cover 100 includes a cover body 110 and a sealing cover 120. The cover body 110 defines an interior accommodating cavity 1111. The accommodating cavity 1111 communicates with the wall of the cover body 110 to form a first opening 1114 and a second opening 1115. The first opening 1114 and the second opening 1115 are separated and connected. Furthermore, the cover body 110 is provided with a mounting position 1116 along the second direction for mounting the rotating shaft of the film removal wheel. The mounting position 1116 communicates with the accommodating cavity 1111, and the mounting position 1116 and the first opening 1114 are separated and connected along the first direction. The sealing cover 120 is connected to the cover body 110. The interior of the sealing cover 120 has a hollow structure 121. The hollow structure 121 extends through both ends of the sealing cover 120, forming a cavity within the sealing cover 120. The hollow structure 121 is connected to the side of the sealing cover 120 that is away from the first opening 1114, forming a third opening 1221. The hollow structure 121 is connected to the first opening 1114. Since the first opening 1114 is formed by the accommodating cavity 1111, and the first opening 1114 is connected to the second opening 1115, the hollow structure 121 is connected to the accommodating cavity 1111 and the second opening 1115. The third opening 1221 is connected to the first opening 1114 and the second opening 1115. The end of the sealing cover 120 that is away from the first opening 1114 is telescopic in a first direction. That is, one end of the sealing cover 120 is connected to the first opening 1114, and the other end can telescopically move in the first direction to change the length of the sealing cover 120.

[0039] Specifically, in one example, when it is necessary to perform a film removal operation on the glass, a film removal wheel is needed to polish the glass. In order to prevent the particulate impurities generated during the polishing process from scratching the glass surface, the dust cover 100 and the film removal wheel need to be used together. Among them, the accommodating cavity 1111 of the cover body 110 and the hollow structure 121 of the sealing cover 120 are used to accommodate the film removal wheel, and the rotating shaft of the film removal wheel is installed in the mounting position 1116 so that the film removal wheel can rotate in the accommodating cavity 1111. The sealing cover 120 is used to extend and retract so that the bottom of the sealing cover 120 and the outer surface of the film removal wheel are in the same plane, that is: during polishing, the film removal wheel has a contact surface with the glass, and the bottom of the sealing cover 120 needs to extend through the sealing cover 120 to be flush with the contact surface. When the film removal wheel contacts the glass, the bottom of the sealing cover 120 also happens to contact the glass. Thus, the sealing cover 120 can be placed at the polishing position to prevent particles generated by polishing from flying out of the cover body 110. Furthermore, placing the sealing cover 120 at the polishing position can reduce the contact surface between the interior of the dust cover 100 and the air, thereby creating a good dust collection environment. At this time, by connecting a vacuum cleaner to the second opening 1115, particles can be sucked from the first opening 1114 to the second opening 1115 and then directed out of the accommodating chamber 1111 for removal, thereby improving film removal efficiency.

[0040] Compared to the conventional dust cover 100 and film removal wheel arrangement, the dust cover 100 provided by the present invention can completely cover the film removal wheel inside the dust cover 100 through the telescopic movement of the sealing cover 120 when the film removal wheel is performing a grinding operation, so that the grinding operation is carried out in a sealed chamber formed by the glass surface, the sealing cover 120 and the cover body 110, thereby preventing particulate impurities generated by grinding from flying out of the cover body 110. Even in the case where the diameter of the film removal wheel is large, the sealing cover 120 can, through its own telescopic characteristics, perform corresponding telescopic expansion and contraction in the first direction according to the size of the film removal wheel, so that the bottom of the sealing cover 120 and the outer surface of the film removal wheel are in the same plane, so that the film removal wheel cover is set in the accommodating cavity 1111 and the hollow structure 121. Therefore, the dust cover 100 provided by the present invention can adapt to film removal wheels of different sizes through the telescopic characteristics of the sealing cover 120, allowing the polishing operation to be performed inside the dust cover 100, so that particles generated by the polishing cannot fly out of the dust cover 100, thus preventing the glass surface from being scratched by flying particles during the polishing process. At the same time, the sealing cover 120 can also form a sealed cavity with the surface of the polished glass, reducing the contact between the interior of the dust cover 100 and the external air, creating a good dust collection environment, so that particulate impurities can be better attracted from the first opening 1114 to the second opening 1115 and then discharged from the receiving cavity 1111.

[0041] In some embodiments, see Figure 2 and Figure 5As shown, the dust cover 100 also includes a seal 130, which is connected to the side of the sealing cover 120 away from the first opening 1114, that is, the end of the sealing cover 120 that performs telescopic movement. The seal 130 is arranged around the hollow structure 121, and the seal 130 is made of a flexible material. Specifically, when performing film removal operations, the seal 130 is used to contact the glass surface. The seal 130 is arranged around the hollow structure 121, so that a good sealed chamber can be formed between the seal 130 and the glass surface when the seal 130 contacts the glass surface. At the same time, since it is necessary to continuously move the film removal wheel to remove the film at various positions on the glass surface during the film removal operation, the use of a flexible seal 130 can prevent the sealing cover 120 from scratching the glass surface during the movement, and the seal 130 contacting the glass surface can clean dust and other impurities on the glass surface during the movement, further improving the efficiency of removing impurities. Since the sealing member 130 is connected to the bottom of the sealing cover 120 and moves along with the sealing cover 120, in this embodiment, the sealing member 130 and the film removal wheel contact the surface of the glass together.

[0042] In some embodiments, see Figure 2 As shown, the cover body 110 includes a support cover 111 and a cover plate 112, and the cover plate 112 is detachably connected to the support cover 111. The cover plate 112 is covered on the support cover 111, thereby defining a accommodating chamber 1111 together with the support cover 111. The accommodating chamber 1111 is used to accommodate the film removal wheel, and under the influence of the rotation of the film removal wheel, the particulate impurities generated during the film removal process will also be accommodated in the accommodating chamber 1111. At the same time, since the film removal wheel is a consumable grinding wheel, the diameter of the film removal wheel will gradually become smaller during use, so the film removal wheel needs to be replaced regularly, and making the cover plate 112 and the support cover 111 detachably connected can facilitate the replacement of the film removal wheel. The sealing cover 120 is detachably connected to the support cover 111 and the cover plate 112.

[0043] In other embodiments, the cover plate 112 and the support cover 111 can also be fixedly connected, so that the length of the first opening 1114 formed by the cover plate 112 and the support cover 111 is greater than the diameter of the film removal wheel, and the width of the first opening 1114 is greater than the thickness of the film removal wheel. In this way, the film removal wheel and the cover body 110 can be detachably connected to realize the replacement of the film removal wheel.

[0044] In some embodiments, see Figure 5As shown, the sealing cover 120 includes a first outer cover 123 and a second outer cover 124, wherein the first outer cover 123 is connected to the second outer cover 124, and the second outer cover 124 covers a portion of the exterior of the first outer cover 123. The second outer cover 124 can move relative to the first outer cover 123 in a first direction, thereby realizing the function of extending and retracting the sealing cover 120. Specifically, the first outer cover 123 is connected to the cover body 110, and the second outer cover 124 is connected to the end of the first outer cover 123 facing away from the cover body 110. When the sealing cover 120 needs to be extended or retracted, the second outer cover 124 is slid along the first direction to extend and retract the sealing cover 120.

[0045] In one example, Figure 5 As shown, the first outer cover 123 and the second outer cover 124 are slidably fitted together, with the first outer cover 123 interferingly positioned within the second outer cover 124. Friction is generated at the contact surface between the first and second outer covers 123, and in a natural state, the second outer cover 124 is fixedly connected to the first outer cover 123 due to this friction. Because the friction is greater than the weight of the second outer cover 124, the second outer cover 124 does not automatically slide relative to the first outer cover 123 in the first direction. When an external force (e.g., a person pulling) is applied to the second outer cover 124, if the external force is greater than the friction, the second outer cover 124 will slide relative to the first outer cover 123 in the first direction, thereby changing the length of the sealing cover 120. The user can then pull the second outer cover 124 to bring the bottom of the second outer cover 124 into contact with the glass surface. When the external force disappears, the second outer cover 124 stops sliding, and the positions of the second outer cover 124 and the first outer cover 123 remain unchanged after the external force disappears, so that the second outer cover 124 is always in contact with the glass surface during the film removal process.

[0046] In another embodiment, Figure 5As shown, the outer wall of the first outer cover 123 is provided with a slide rail, and the inner wall of the second outer cover 124 is provided with a slide member. The second outer cover 124 is movably connected to the first outer cover 123 via the slide member and the slide rail. The slide member and the slide rail allow the second outer cover 124 to slide relative to the first outer cover 123 in a first direction to change the length of the sealing cover 120. In this embodiment, the second outer cover 124 naturally droops in the first direction under the action of gravity. When the second outer cover 124 contacts the glass surface, the glass surface provides a reaction force to the second outer cover 124, which pushes the second outer cover 124 to slide in the first direction (i.e., upward) until the film removal wheel contacts the glass surface, thereby achieving contact between the sealing cover 120 and the film removal wheel. In other embodiments, fixing devices, such as a latch and a pin hole, may be provided on the first and second outer covers 123, 124. By providing the pin holes on the first and second outer covers 123, 124, and inserting the latch into the pin hole, the second outer cover 124 is restricted from sliding relative to the first outer cover 123 under gravity. If it is necessary to slide the second outer cover 124 to change the length of the sealing cover 120, the latch can be removed and inserted into another pin hole to achieve the desired length change.

[0047] In other embodiments, the sealing cover 120 may not include the first outer cover 123 and the second outer cover 124. For example, the sealing cover 120 may be made of a bellows, and the outer surface of the sealing cover 120 may have corrugations arranged at intervals. Compressing the sealing cover 120 may cause the sealing cover 120 to fold along the corrugations on the outer surface, and stretching the sealing cover 120 may cause the sealing cover 120 to unfold at the corrugations, thereby achieving the effect of changing the length of the sealing cover 120. When performing a film removal operation, if the bottom of the sealing cover 120 first contacts the glass, compressing the sealing cover 120 along the first direction may cause the sealing cover 120 to fold along the corrugations to shorten the length of the sealing cover 120 until the film removal wheel also contacts the glass surface.

[0048] In some embodiments, see Figures 3 to 5As shown, the dust cover 100 further includes a partition 140, which is connected to the inner wall of the cover body 110 and is disposed in the accommodating cavity 1111. The partition 140 is used to separate the accommodating cavity 1111, so that the accommodating cavity 1111 is formed with a mounting cavity 1112 and a guide channel 1113. The mounting cavity 1112 is used to accommodate the film removal wheel, and the guide channel 1113 is used to conduct particulate impurities generated during the film removal process to the outside world. The mounting cavity 1112 and the guide channel 1113 are connected. Specifically, one end of the guide channel 1113 is connected to the first opening 1114, and the other end is connected to the second opening 1115, while the mounting cavity 1112 is connected to the first opening 1114. When the film removal wheel is working in the installation cavity 1112, the film removal wheel contacts the glass surface through the third opening 1221, and the dust and other particulate impurities generated during processing are sealed in the hollow structure 121 by the sealing cover 120. The hollow structure 121 is connected to the guide channel 1113 through the first opening 1114. Thus, the hollow structure 121, the first opening 1114, the guide channel 1113, and the second opening 1115 are connected to form a channel that can be used to discharge particulate impurities. Therefore, the particulate impurities in the hollow structure 121 can be discharged from the second opening 1115 through the guide channel 1113.

[0049] In specific applications, a vacuum cleaner can be used to accelerate the discharge of particulate impurities in the guide channel 1113. For example, a vacuum cleaner can be connected to the second opening 1115 to connect the vacuum cleaner to the guide channel 1113. When the vacuum cleaner is working, the gas in the guide channel 1113 is sucked through the second opening 1115, thereby forming a negative pressure airflow. The particulate impurities in the hollow structure 121 of the sealing cover 120 and the particulate impurities in the accommodating cavity 1111 will enter the guide channel 1113 under the action of the vacuum cleaner and flow along the guide channel 1113 to the second opening 1115 to be discharged to the outside world, thereby achieving the cleaning of impurities in the installation cavity 1112 and the guide channel 1113. At the same time, since the installation cavity 1112 and the guide channel 1113 are connected, it can avoid the situation where some particulate impurities are hidden in the installation cavity 1112 and cannot be cleaned.

[0050] Further, in some embodiments, see Figure 3As shown, the cover body 110 includes an extension portion 113, which is formed by extending from the inner wall of the cover body 110 toward the partition portion 140. The extension portion 113 is connected to the partition portion 140, wherein the extension portion 113, the partition portion 140 and the inner wall of the cover body 110 jointly define a guide channel 1113. Specifically, the partition portion 140 cooperates with the inner walls on both sides of the cover body 110 to separate the accommodating cavity 1111 into the installation cavity 1112 and the guide channel 1113, wherein the extension portion 113 is molded on the inner wall of the cover body 110 that forms the guide channel 1113, and is formed by extending from the inner wall on this side toward the partition portion 140 until the extension portion 113 is connected to the partition portion 140 to form a closed structure. The extension portion 113, the partition portion 140 and the inner wall of the cover body 110 make the guide channel 1113 in a closed state on all sides. This setting enables the guide channel 1113 to communicate with the outside world only through the first opening 1114 and the second opening 1115, thereby allowing particulate impurities to be discharged to the outside world only along a fixed path, that is: the particulate impurities enter the guide channel 1113 from the first opening 1114, then are conducted from the guide channel 1113 to the second opening 1115, and finally are discharged to the outside world from the second opening 1115, thereby avoiding the situation where the particulate impurities fly out of the guide channel 1113 from the side wall of the guide channel 1113 after entering the guide channel 1113, thereby improving the efficiency of removing impurities.

[0051] In some embodiments, see Figure 5 As shown, the cover body 110 has a first inner wall 114 and a second inner wall 115 opposite to each other, wherein the partition 140, the first inner wall 114 and the second inner wall 115 are bent along a third direction to form a curved structure, that is, the partition 140, the first inner wall 114 and the second inner wall 115 are bent in a direction away from the installation position 1116 to form a curved structure. The partition 140 and the first inner wall 114 have the same bending direction, and the two together define a guide channel 1113. The partition 140 and the second inner wall 115 are arranged opposite to each other, and the two together define a mounting cavity 1112, and the third direction is perpendicular to the first direction and the second direction. Specifically, in one example, refer to Figure 5 As shown, the partition 140 and the first inner wall 114 are bent toward the left to form a curved structure, while the second inner wall 115 is bent toward the right to form a curved structure.

[0052] In one example, the direction of rotation of the film removal wheel is clockwise. When dust particles are generated during the film removal process, the dust particles will have a centrifugal force under the action of the film removal wheel, so that the dust particles will also follow the film removal wheel to move clockwise. Since the guide channel 1113 is located on the left side of the film removal wheel in the embodiment, when dust particles are generated, the dust particles will be moved clockwise by the film removal wheel. This will reduce the time it takes to conduct from the first opening 1114 to the second opening 1115, and since the guide channel 1113 is a curved structure, it can reduce the collision of dust particles with the inner wall of the guide channel 1113, thereby accelerating the conduction speed of dust particles in the guide channel 1113, thereby improving the removal efficiency of dust particles. In addition, the use of a curved structure can prevent dust particles from accumulating in the guide channel 1113, avoiding the situation where the guide channel 1113 is blocked due to the accumulation of dust and dirt. At the same time, the design of the curved structure also makes it easier to clean the dust accumulated in the guide channel 1113. If dust particles remain in the guide channel 1113 , the curved structure can allow the accumulated dust to slide down the guide channel 1113 , thereby facilitating regular cleaning and maintenance of the dust cover 100 .

[0053] Further, see Figure 5 As shown, along the first direction, there is a first spacing h1 between the side of the partition 140 facing the first opening 1114 and the side of the cover body 110 connected to the sealing cover 120. When the film removal wheel is performing glass film removal, the generated particulate impurities will rotate along with the rotation of the film removal wheel, and the dust particles will have centrifugal force. In this embodiment, the length of the partition 140 is smaller than the length of the cover body 110 in the first direction, and there is a first spacing h1 between the side of the partition 140 facing the first opening 1114 and the side of the cover body 110 connected to the sealing cover 120. By reducing the area of ​​the partition 140, the impact of dust particles on the surface of the partition 140 can be reduced, thereby increasing the amount of impurity particles entering the guide channel 1113 under the action of centrifugal force per unit time, thereby improving the efficiency of removing impurities.

[0054] ‌ The following describes the film removal device 10 according to the second embodiment of the present invention with reference to the accompanying drawings. Figures 1 to 6As shown, the film removal device 10 includes the dust cover 100 and the film removal wheel 200 described in any of the above embodiments. The film removal wheel 200 is connected to the cover body 110, and the film removal wheel 200 is accommodated in the accommodating cavity 1111 and the hollow structure 121. There is a second distance h2 between the center point of the mounting position 1116 and the third opening 1221 along the first direction. The second distance h2 is not greater than the radius of the film removal wheel, so that when the film removal wheel 200 is located in the accommodating cavity 1111 and the hollow structure 121, a part of the film removal wheel 200 is still located outside the hollow structure 121, so that the film removal wheel 200 will normally contact the glass before the sealing cover 120, or the film removal wheel 200 and the sealing cover 120 will normally contact the glass at the same time.

[0055] Specifically, in one embodiment, when film removal is required, the film removal wheel 200 is accommodated in the accommodating cavity 1111 and the hollow structure 121, and the bottom of the film removal wheel 200 and the sealing member 130 are in contact with the glass surface. This allows the film removal wheel 200 to remove film from the glass while the dust cover 100 and the glass surface form a sealed working space to prevent particulate impurities generated during grinding from flying out of the cover 110 and scratching the glass surface. When particulate impurities are generated during the grinding process, the dust collector 300 draws the particulate impurities from the first opening 1114 into the guide channel 1113, and then adsorbs them from the guide channel 1113 to the second opening 1115 and guides them out to the outside world, thereby completing the removal of the particulate impurities. The film removal device 10 extends the sealing cover 120 to allow the film removal wheel 200 to contact the glass, so that the dust cover 100 and the glass surface cooperate to form a good dust collection environment, preventing impurities from flying and scratching the glass surface and reducing the contact area between the cover and the air.

[0056] In some embodiments, see Figure 2 、 Figure 6 and Figure 7 As shown, the film removal device 10 further includes a fixed plate 400 and a vacuum cleaner 300. The fixed plate 400 is used to connect the vacuum cleaner 300 to the second opening 1115 to remove impurities from the second opening 1115. One side of the fixed plate 400 is connected to the vacuum cleaner 300. A first through-hole 410 is provided on the side of the fixed plate 400 connected to the vacuum cleaner 300. The first through-hole 410 penetrates the fixed plate 400 in a first direction, and the vacuum cleaner 300 is connected to the first through-hole 410. The dust cover 100 is detachably connected to the side of the fixed plate 400 facing away from the vacuum cleaner 300. The first through-hole 410 is connected to the second opening 1115, so that when impurities are generated, the vacuum cleaner 300 absorbs them from the first opening 1114 to the second opening 1115 to remove them, thereby protecting the glass surface.

[0057] In some embodiments, see Figures 2 to 7As shown, the film removal device 10 includes a driving device 500, which is connected to the cover body 110 and the film removal wheel 200, and the driving device 500 is used to drive the film removal wheel 200 to rotate. A mounting position 1116 is provided on one side of the cover body 110 along the second direction, wherein the second direction is perpendicular to the first direction, and the mounting position 1116 passes through the side wall of the cover body 110 so that the outside world can communicate with the mounting cavity 1112. Part of the driving device 500 is passed through the mounting position 1116 and is provided in the accommodating cavity 1111, specifically in the mounting cavity 1112. The driving device 500 located in the mounting cavity 1112 is used to connect to the film removal wheel 200 and drive the film removal wheel 200 to rotate to perform the film removal operation. Furthermore, a portion of the drive device 500 is disposed within the mounting cavity 1112, allowing the film removal wheel 200 to be spaced apart from the inner wall of the accommodating cavity 1111. This prevents the film removal wheel 200 from damaging the inner wall of the accommodating cavity 1111 during rotation, thereby increasing the service life of the dust cover 100. In this embodiment, the drive device 500 is specifically a motor. In other embodiments, the film removal device 10 may also drive the film removal wheel 200 via hydraulic transmission, shaft transmission, gear transmission, or other methods.

[0058] Further, in some embodiments, see Figure 6 and Figure 7 As shown, the film removal device 10 also includes a bracket 600, which is connected to the cover body 110 along the second direction. The bracket 600 is connected to the side of the cover body 110 where the mounting position 1116 is provided. The bracket 600 is used to fix the driving device 500, thereby improving the stability of the film removal device 10. The side of the bracket 600 facing away from the cover body 110 is recessed along the second direction to form a receiving groove 610, and the driving device 500 is provided in the receiving groove 610. Specifically, a connecting hole is provided in the receiving groove 610, which passes through the bracket 600 along the second direction and is connected to the mounting position 1116. Therefore, when the driving device 500 is connected to the cover body 110 via the bracket 600, the driving device 500 can connect and fix the film removal wheel 200 through the connecting hole and the mounting position 1116. In this embodiment, the driving device 500 is detachably connected to the bracket 600 by screws. In other embodiments, the drive device 500 can be connected to the bracket 600 by snap-fit ​​connection, adhesive bonding, or integral molding. Meanwhile, the side of the bracket 600 facing away from the sealing cover 120 is connected to the fixing plate 400. The bracket 600 not only provides support for the drive device 500, but the bracket 600 and the fixing plate 400 also jointly secure the dust cover 100, reducing vibration of the dust cover 100 caused by the operation of the film removal wheel 200.

However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
