A film coating device for glass production

Abstract

The application discloses a film covering device for glass production and relates to the technical field of glass production and processing equipment, which comprises a conveying belt, a film feeding roller, a negative pressure film pasting mechanism and a side edge stacking mechanism. The output end of a gas cylinder drives a connecting rod and a lifting frame to descend simultaneously, and the synchronous descending of a mounting frame enables the upper edge sealing slotted plates on the two sides of the mounting frame to abut against the upper surface side edge area of the glass, so that the film can be stably laid on the upper surface of the glass under the negative pressure environment, and the film on the glass surface is prevented from being obliquely pasted or wrinkled due to the residual airflow of dust removal during the film covering process. During the descending of the lifting frame, the lower edge sealing slotted plate is turned over to the lower surface side edge area of the glass, and under the joint action of the slot of the upper edge sealing slotted plate and the slot of the lower edge sealing slotted plate, the film can form a stacking state corresponding to the upper and lower sides of the glass and be negatively shaped, so that the film surface of the edge of the film covered glass is prevented from being abraded during the unloading process, and the product quality is affected.

Description

Technical Field

[0001] This invention relates to the field of glass production and processing equipment technology, and specifically to a coating device for glass production. Background Technology

[0002] Coated glass refers to glass with one or more layers of film covering it. It is mainly used to strengthen the glass and block ultraviolet rays, so as to play a role in protection and heat insulation. Therefore, the coating machine or coating device is one of the most important pieces of equipment in the production process of coated glass. Most existing technologies use film-applying rollers to automatically coat the glass on the conveyor belt.

[0003] However, after long-term use, the existing technology still has some drawbacks, such as: First, dust can accumulate on the surface of the glass and the conveyor belt. The existing technology uses a blower to remove dust from the glass and conveyor belt before lamination. The pre-cleaning environment helps maintain the lamination quality, but the residual airflow in the environment can affect the flatness of the film itself, causing the film to be applied at an angle or wrinkled on the glass surface during the lamination process. Second, after the glass is laminated, a robotic arm is often used to automatically unload the glass. To prevent the suction cups of the robotic arm from causing air pockets on the newly applied film, a double-sided clamping method is usually used. However, the clamping process of the robotic arm can cause some wear on the edge of the film surface of the laminated glass, affecting product quality. Manual unloading, on the other hand, poses safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a coating apparatus for glass production to overcome the aforementioned defects caused by the prior art.

[0005] A coating apparatus for glass production includes a conveyor belt, a film feeding roller, a negative pressure film application mechanism, and a side stacking mechanism. The conveyor belt is equipped with a feed rack, and the side end of the feed rack is equipped with an inclined guide block. The lower end of the feed rack is symmetrically equipped with straightening rollers. The film feeding roller is mounted on the feed rack. The negative pressure film application mechanism is mounted on the feed rack and is used to coat the upper surface and sides of the glass. The side stacking mechanism is also mounted on the feed rack and is used to seal and stack the film sheets coated on the sides of the glass.

[0006] Preferably, the negative pressure film-applying mechanism includes a cylinder, a negative pressure generator, and a mounting frame. The cylinder is mounted on the upper end of the feed rack via a base. The base has clearance openings on both sides. A connecting rod is installed at the output end of the cylinder. The mounting frame is detachably mounted on the lower end of the connecting rod. Upper edge sealing grooved plates are symmetrically installed at both ends of the mounting frame. The negative pressure generator is mounted on the feed rack and placed in the middle of the conveyor belt.

[0007] Preferably, the side stacking mechanism includes a lifting frame, a rack, and a tilting shaft. The lifting frame is installed at the top of the connecting rod and placed in the clearance opening. There are two racks symmetrically installed on both sides of the lifting frame. There are two tilting shafts symmetrically rotatably installed on both sides of the material feeder. A gear is coaxially installed in the middle of the tilting shaft. The gear meshes with the rack. The side end of the tilting shaft is also equipped with a lower sealing edge slotted plate via a curved arm.

[0008] Preferably, the directional roller is positioned directly below the inclined guide block and engages with both ends of the glass.

[0009] Preferably, the grooves of the lower edge sealing plate correspond to those of the upper edge sealing plate.

[0010] Preferably, the rotation process of the flipping shaft has no rigid contact with the conveyor belt.

[0011] The advantages of this invention are:

[0012] By setting a negative pressure film application mechanism and a side stacking mechanism on the material feeder, the output end of the cylinder drives the connecting rod and the lifting frame to descend simultaneously. The synchronous descent of the mounting frame allows the upper sealing grooved plates on both sides of the mounting frame to abut against the side area of ​​the upper surface of the glass. This allows the film to be stably laid flat on the upper surface of the glass under negative pressure, avoiding the residual airflow from dust removal from causing the film to be applied at an angle or wrinkled on the glass surface during the film application process.

[0013] During the descent of the lifting frame, the lower edge sealing and grooving plate will be rotated to the lower surface side area of ​​the glass. Under the combined action of the grooves of the upper and lower edge sealing and grooving plates, the film will form a corresponding stacked state on both sides of the glass and be negatively shaped, avoiding wear on the edge film surface of the coated glass during the unloading process, thus affecting product quality.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 5 As shown, a coating device for glass production includes a conveyor belt 1, a film feeding roller 2, a negative pressure film application mechanism 3, and a side stacking mechanism 4. A feed rack 5 is provided on the conveyor belt 1, and an inclined guide block 6 is provided on the side end of the feed rack 5. A symmetrically mounted straightening roller 7 is installed on the lower end of the feed rack 5. The film feeding roller 2 is mounted on the feed rack 5. The negative pressure film application mechanism 3 is mounted on the feed rack 5 and is used to coat the upper surface and sides of the glass. The side stacking mechanism 4 is also mounted on the feed rack 5 and is used to seal and stack the film sheets applied to the sides of the glass.

[0022] In this embodiment, the negative pressure film applicator 3 includes a cylinder 301, a negative pressure generator 302, and a mounting frame 303. The cylinder 301 is mounted on the upper end of the feed rack 5 via a base 304. The base 304 has clearance openings 305 on both sides. A connecting rod 306 is mounted on the output end of the cylinder 301. The mounting frame 303 is detachably mounted on the lower end of the connecting rod 306. Upper edge sealing slotted plates 307 are symmetrically mounted on both ends of the mounting frame 303. The negative pressure generator 302 is mounted on the feed rack 5 and placed in the middle of the conveyor belt 1.

[0023] In this embodiment, the side stacking mechanism 4 includes a lifting frame 401, a rack 402, and a flipping shaft 403. The lifting frame 401 is installed at the top of the connecting rod 306 and placed in the clearance opening 305. There are two racks 402, which are symmetrically installed on both sides of the lifting frame 401. There are two flipping shafts 403, which are symmetrically rotatably installed on both sides of the material feeder 5. A gear 404 is coaxially installed in the middle of the flipping shaft 403. The gear 404 meshes with the rack 402. The side end of the flipping shaft 403 is also equipped with a lower sealing edge slotted plate 406 through a crank arm 405.

[0024] It should be noted that the mounting frame 303 can be replaced with the corresponding structure in a timely manner according to the glass model or shape to be coated, such as curved glass. The film feeding roller 2 is a power feeding device, and the film feeding speed is matched with the glass conveying speed on the conveyor belt 1.

[0025] In this embodiment, the straightening roller 7 is placed directly below the inclined guide block 6 and cooperates with both sides of the glass. The groove of the lower sealing edge slotted plate 406 corresponds to the groove of the upper sealing edge slotted plate 307.

[0026] Furthermore, the rotation process of the flipping shaft 403 does not involve rigid contact between it and the conveyor belt 1.

[0027] Working process and principle: In the process of using this invention, the glass to be coated is first fed into the device through the inclined guide block 6. The glass placed on the conveyor belt 1 is guided and transported in the center by the limiting of the two sides in the straightening rollers 7, and then the following steps are performed:

[0028] Start the negative pressure generator 302 and the film feeding roller 2 to create a negative pressure environment between the conveyor belt 1 and the glass in the material feeder 5. The dust in the film coating environment is sucked away, thereby adsorbing the film on the film feeding roller 2 onto the upper surface of the glass. At the same time, start the cylinder 301 so that its output end drives the connecting rod 306 and the lifting frame 401 to move down at the same time. The downward movement of the connecting rod 306 will drive the mounting frame 303 to move down synchronously, so that the upper sealing grooved plates 307 on both sides of the mounting frame 303 abut against the side area of ​​the upper surface of the glass. At this time, the conveying of glass on the conveyor belt 1 is stopped.

[0029] During the descent of the lifting frame 401, the rack 402 drives the gear 404 to rotate, which in turn drives the lower sealing and grooving plate 406 to rotate to the lower side area of ​​the glass via the flipping shaft 403 and the crank arm 405. At this time, under negative pressure, the film can be shaped and adsorbed on the glass. That is, the film on the upper side of the glass is placed in the groove of the upper sealing and grooving plate 307, and the film on the lower side of the glass is placed in the groove of the lower sealing and grooving plate 406, so that the film forms a corresponding stacked state on both sides of the glass and is shaped under negative pressure. At this time, the coated glass can be directly clamped and unloaded by a robotic arm, or the coated glass stacked on the side can be manually held. The film stacking area is a hidden installation area and will not affect the actual use of the coated glass. Then, the cylinder 301 is reversed to reset its output end and continue to transport the coated glass on the conveyor belt 1.

[0030] Based on the above, the present invention sets a negative pressure film-applying mechanism 3 and a side stacking mechanism 4 on the material feeder 5. The output end of the cylinder 301 drives the connecting rod 306 and the lifting frame 401 to descend simultaneously. The synchronous descent of the mounting frame 303 makes the upper sealing edge slotted plates 307 on both sides of the mounting frame 303 abut against the side area of ​​the upper surface of the glass. This allows the film to be stably laid flat on the upper surface of the glass under negative pressure, avoiding the residual airflow from dust removal from causing the film to be applied at an angle or wrinkled on the glass surface during the film-applying process.

[0031] During the descent of the lifting frame 401, the lower edge sealing and grooving plate 406 will be rotated to the lower surface side area of ​​the glass. Under the combined action of the grooves of the upper edge sealing and grooving plate 307 and the lower edge sealing and grooving plate 406, the film will form a corresponding stacked state on both sides of the glass and be negatively pressure shaped, so as to avoid wear on the edge film surface of the coated glass during the unloading process, thus affecting the product quality.

[0032] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
