Description

Technical Field

[0001] This invention relates to the field of glass film application technology, and more particularly to an automatic glass film application device for both the top and bottom surfaces. Background Technology

[0002] To protect the glass surface from scratches during storage, transportation, and slab grinding, effective protection is required. Therefore, a glass film is applied to the glass surface to ensure that it is not scratched during storage, transportation, and slab grinding. Thus, a glass film application device is needed to apply film to both sides of the glass.

[0003] Existing automatic glass film application devices often have issues with dust adhering to their surfaces during the application process. They fail to clean both sides of the glass simultaneously and move quickly to the application position. Furthermore, as the film rolls are used, their diameter decreases, causing them to not adhere properly to the glass sides, resulting in air bubbles after film application.

[0004] Therefore, an automatic film application device for the top and bottom surfaces of glass is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that as the diameter of the film roll decreases with the use of the film roll, the film rolls on both sides of the glass cannot be properly adhered to the glass, resulting in air bulges after film is applied to both sides of the glass. Therefore, this invention proposes an automatic film application device for the top and bottom surfaces of glass.

[0006] To achieve the above objectives, the present invention provides the following technical solution: Design an automatic glass top and bottom film application device, including a film application table assembly. The top front end of the film application table assembly is equipped with a pushing and feeding mechanism for moving the glass. The middle of the film application table assembly is equipped with a cleaning mechanism for brushing and cleaning the top and bottom surfaces of the glass. The top of the film application table assembly and located behind the cleaning mechanism is equipped with a film application mechanism. Both ends of the film application mechanism are equipped with driving and moving mechanisms. The film application table assembly includes a film application table, with support legs fixed at the four corners of the bottom end of the film application table. A groove for installing the cleaning mechanism is opened in the middle of the top end of the film application table, and an installation slot for installing the film application mechanism is opened on the rear side of the groove. The pushing and feeding mechanism includes a first pushing plate slidably installed on the top front end of the film application table, and a second pushing plate is installed on the inner side of the first pushing plate; The cleaning mechanism includes a mounting frame fixed to the middle of the top of the film application table, and cleaning pads are evenly installed at the bottom of the mounting frame and the top of the inner groove.

[0007] Furthermore, the film application table is horizontally positioned, with a first side plate fixed at the center of its front end. A first electric push rod is horizontally installed on the outer side of the first side plate, and the telescopic end of the first electric push rod is connected to the outer side of the first push plate.

[0008] Furthermore, the first push plate has a C-shaped structure, and a second electric push rod is fixedly connected to its outer side and located on both sides of the first electric push rod. The telescopic ends of the second electric push rod are fixedly connected to the two outer ends of the second push plate. The second push plate is slidably installed on the top of the film application table, and its height is less than the distance between the two cleaning pads.

[0009] Furthermore, the front ends of the film application table are fixed with second side plates, the surface of the second side plates is provided with first guide holes, and the outer ends of the first push plate are fixed with first guide rods, which slide horizontally through the first guide holes.

[0010] Furthermore, the groove is a rectangular groove structure and is horizontally arranged, with first connecting holes at both ends of its bottom end. The mounting bracket is a C-shaped structure and spans across the top of the groove, with second connecting holes at both ends. The second connecting holes and the first connecting holes are vertically aligned.

[0011] Furthermore, an abutment plate is connected to the outer side of the cleaning pad. One abutment plate is securely installed inside the groove. The top of the cleaning pad protrudes upward from the top of the film application table. The other abutment plate is securely installed inside the mounting frame. Both abutment plates are horizontally arranged and parallel to each other.

[0012] Furthermore, connecting rods are fixed to both outer ends of the two abutment plates. The connecting rods pass through the first connecting hole and the second connecting hole respectively. The connecting rods are threaded rods with nuts attached to their surfaces. The two abutment plates are fastened to the groove and the mounting bracket respectively through the nuts.

[0013] Furthermore, the driving and moving mechanism includes support frames fixed to the upper and lower sides of the film application platform and spanning both ends of the mounting groove. A fixing plate is fixed at the middle position between the upper and lower ends of the two support frames. A driving rod is rotatably installed at the middle position between the two support frames. A first motor is installed at the top of the driving rod. A second guide rod is fixed between the two support frames and at the position on both sides of the driving rod.

[0014] Furthermore, the film-applying mechanism includes a drive plate mounted on the surfaces of the second guide rod and the drive rod. The drive plate has a drive hole in the middle, through which the drive rod rotates. The drive plate has second guide holes at both ends, through which the second guide rod slides. A rotating rod is rotatably mounted between the two drive plates. A film-applying roll is wound around the surface of the rotating rod. A first gear is fixed at one end of the rotating rod, located inside the drive plate. A second motor is fixedly mounted on one side of the drive plate. A second gear is mounted inside the second motor via a rotating shaft. The second gear meshes with the outside of the first gear.

[0015] Furthermore, the support frame has a U-shaped structure and is vertically arranged. The drive rod and the second guide rod are both arranged to pass through the inner ends of the mounting groove. The first motor is fixedly installed on the top of the fixing plate. The drive hole is a threaded hole structure. The drive plate is a rectangular plate structure and is horizontally arranged at the upper and lower positions of both ends of the mounting groove. Its length dimension is smaller than the width dimension of the mounting groove. The top of the film roll below protrudes upward from the top of the film application table. The two film rolls rotate synchronously and in opposite directions.

[0016] The automatic film application device for the top and bottom surfaces of glass proposed in this invention has the following advantages: 1. The present invention installs a first push plate and a second push plate at the front end of the film application table. A first electric push rod drives the first push plate and the second push plate to move. Then, the second electric push rod drives the second push plate to move, continuously pushing the glass between two cleaning pads and into the space between two film application rolls for film application. This can automatically push the glass to be fed for cleaning and film application, and extend the distance the glass moves.

[0017] 2. In the cleaning mechanism of this invention, the height of the upper abutment plate and the cleaning pad are adjusted by a connecting rod inside the mounting frame according to the thickness of the glass, thereby adjusting the distance between the two cleaning pads and keeping the upper and lower cleaning pads abutting against the two sides of the glass as it moves, thus cleaning and removing dust from both sides of the glass.

[0018] 3. According to the thickness of the glass, the present invention uses two first motors to operate synchronously, driving two film rolls to move up and down synchronously, so that the upper and lower film rolls abut against and adhere to both sides of the glass. At the same time, the second motor drives the second gear to rotate, driving the two rotating rods and the film rolls to rotate synchronously and in opposite directions, to synchronously apply film to both sides of the glass, completing the synchronous film application on both sides. As the film rolls apply film to both sides of the glass, their diameter gradually decreases. The drive plate is driven to move through the drive rod and drive hole, so that the two film rolls gradually approach each other and always abut against and adhere to both sides of the glass, thereby keeping the film on both sides of the glass tightly abutting and reducing the occurrence of air bubbles.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The figure shows an automatic glass top and bottom film application device, including a film application table assembly 1. A pushing and feeding mechanism 2 for pushing the glass to move is installed at the top front end of the film application table assembly 1. A cleaning mechanism 3 for brushing and cleaning the top and bottom surfaces of the glass is installed in the middle of the film application table assembly 1. A film application mechanism 5 is installed at the top of the film application table assembly 1 and at the rear side of the cleaning mechanism 3. A drive moving mechanism 4 is installed at both ends of the film application mechanism 5.

[0023] The film application table assembly 1 includes a film application table 11, with support legs 12 fixed at the four corners of the bottom end of the film application table 11. A groove 13 for installing a cleaning mechanism 3 is opened in the middle of the top end of the film application table 11, and an installation slot 15 for installing the film application mechanism 5 is opened on the rear side of the groove 13.

[0024] The feeding mechanism 2 includes a first push plate 26 that is slidably installed at the top front end of the film application table 11, and a second push plate 27 is installed on the inner side of the first push plate 26.

[0025] The film application table 11 is set horizontally, with a first side plate 24 fixed in the middle of its front end. A first electric push rod 23 is horizontally installed on the outer side of the first side plate 24, and the telescopic end of the first electric push rod 23 is connected to the outer side of the first push plate 26.

[0026] The first electric push rod 23 drives the first push plate 26 and the second push plate 27 to move, pushing the glass towards the cleaning mechanism 3 and into the space between the two cleaning pads 36 for cleaning.

[0027] The first push plate 26 has a C-shaped structure, and a second electric push rod 25 is fixedly connected to its outer side and located on both sides of the first electric push rod 23. The telescopic ends of the second electric push rod 25 are fixedly connected to the two outer ends of the second push plate 27. The second push plate 27 is slidably installed on the top of the film application table 11, and its height is less than the distance between the two cleaning pads 36.

[0028] The front ends of the film application table 11 are fixed with second side plates 21. The surface of the second side plates 21 has a first guide hole 22. The outer ends of the first push plate 26 are fixed with first guide rods 28. The first guide rods 28 slide horizontally through the first guide hole 22.

[0029] The second electric push rod 25 drives the second push plate 27 to move, continuously pushing the glass between the two cleaning pads 36 and between the two film rolls 52 for film application. It can automatically push the glass to be fed for cleaning and film application, extending the distance the glass moves.

[0030] The cleaning mechanism 3 includes a mounting bracket 31 fixed to the middle of the top of the film application table 11, and cleaning pads 36 are evenly installed on the bottom of the mounting bracket 31 and the top of the inside of the groove 13.

[0031] The groove 13 is a rectangular groove structure and is horizontally set. The bottom end has two first connecting holes 14. The mounting bracket 31 is a C-shaped structure and spans across the top of the groove 13. The two ends have second connecting holes 32. The second connecting holes 32 and the first connecting holes 14 are aligned vertically.

[0032] The outer side of the cleaning pad 36 is connected to an abutment plate 35. One abutment plate 35 is fixedly installed inside the groove 13. The top of the cleaning pad 36 protrudes upward from the top of the film application table 11. The other abutment plate 35 is fixedly installed inside the mounting bracket 31. Both abutment plates 35 are horizontally arranged and parallel to each other.

[0033] Depending on the thickness of the glass, the height of the upper abutment plate 35 and the cleaning pad 36 is adjusted inside the mounting bracket 31 via the connecting rod 33, thereby adjusting the distance between the two cleaning pads 36, keeping the upper and lower cleaning pads 36 abutting against the sides of the glass as it moves, and cleaning and removing dust from both sides of the glass.

[0034] Both outer ends of the two abutment plates 35 are fixed with connecting rods 33. The connecting rods 33 pass through the first connecting hole 14 and the second connecting hole 32 respectively. The connecting rods 33 are threaded rods with nuts 34 connected to their surfaces. The two abutment plates 35 are fastened to the groove 13 and the mounting bracket 31 respectively through the nuts 34.

[0035] After a period of use, the cleaning pad 36 can be disassembled, replaced, and maintained via the connecting rod 33 and nut 34 to keep the cleaning pad 36 clean and facilitate simultaneous cleaning and dust removal on both sides of the glass.

[0036] The driving moving mechanism 4 includes a support frame 41 fixed to the upper and lower sides of the film application table 11 and spanning both ends of the mounting groove 15. A fixing plate 45 is fixed at the middle position between the upper and lower ends of the two support frames 41. A driving rod 43 is rotatably installed at the middle position between the two support frames 41. A first motor 44 is installed at the top of the driving rod 43. A second guide rod 42 is fixed between the two support frames 41 and at the position on both sides of the driving rod 43.

[0037] The support frame 41 has a U-shaped structure and is vertically arranged. The drive rod 43 and the second guide rod 42 are both arranged to pass through the two ends of the mounting groove 15. The first motor 44 is fixedly installed on the top of the fixing plate 45.

[0038] Based on the thickness of the glass, the two first motors 44 are selected from the same model and maintain the same speed. The two first motors 44 run synchronously, driving the two drive rods 43 to rotate synchronously, and driving the drive plate 53 to move through the drive hole 57, so that the drive plates 53 at both ends of the rotating rod 51 move synchronously, thereby driving the two film rolls 52 to move up and down synchronously.

[0039] Moreover, as the film roll 52 applies film to both sides of the glass, its diameter gradually decreases. At the same time, the first motor 44 operates and drives the drive plate 53 to move through the drive rod 43 and drive hole 57, so that the two film rolls 52 gradually approach each other and always abut against and adhere to both sides of the glass, thereby keeping the film on both sides of the glass in tight contact and reducing the occurrence of air bubbles.

[0040] The film application mechanism 5 includes a drive plate 53 mounted on the surfaces of the second guide rod 42 and the drive rod 43. A drive hole 57 is opened in the middle of the drive plate 53, through which the drive rod 43 rotates. Second guide holes 58 are opened at both ends of the drive plate 53, through which the second guide rod 42 slides. A rotating rod 51 is rotatably mounted in the middle between the two drive plates 53. A film application roll 52 is wound on the surface of the rotating rod 51. A first gear 54 is fixed at one end of the rotating rod 51 and located inside the drive plate 53. A second motor 56 is fixedly mounted on one side of the drive plate 53. A second gear 55 is mounted on the inner side of the second motor 56 via a rotating shaft. The second gear 55 is meshed with the outer side of the first gear 54.

[0041] The drive hole 57 is a threaded hole structure, the drive plate 53 is a rectangular plate structure, and is horizontally set at the upper and lower positions at both ends of the mounting groove 15. Its length dimension is smaller than the width dimension of the mounting groove 15. The top of the film roll 52 below protrudes upward from the top of the film application table 11. The two film rolls 52 rotate synchronously and in opposite directions.

[0042] As the glass is pushed to the top of the mounting groove 15 by the first push plate 26 and the second push plate 27, the upper and lower film rolls 52 abut against and adhere to the sides of the glass. At the same time, the second motor 56 drives the second gear 55 to rotate and meshes with the first gear 54 to rotate. The two second motors 56 are of the same model and maintain the same speed. The two second motors 56 run synchronously, thereby driving the two rotating rods 51 and the film rolls 52 to rotate synchronously and in opposite directions.

[0043] Therefore, both sides of the glass can be simultaneously coated with film, and the glass can be driven to move backwards towards the film coating platform 11 by the abutting friction force, so that the glass can complete the simultaneous coating of the upper and lower sides while moving out of the top of the mounting groove 15.

[0044] Working method: A first push plate 26 and a second push plate 27 are installed at the front end of the film application table 11. Therefore, the glass is placed horizontally at the front end of the film application table 11 and the surface of the film application table 11 is kept clean. The first electric push rod 23 and the second electric push rod 25 are controlled by an external controller connected by wires. First, the first electric push rod 23 drives the first push plate 26 and the second push plate 27 to move, pushing the glass towards the cleaning mechanism 3 and into the space between the two cleaning pads 36 for cleaning.

[0045] Then, the second electric push rod 25 drives the second push plate 27 to move, continuously pushing the glass between the two cleaning pads 36 and into the space between the two film rolls 52 for film application. This can automatically push the glass to be fed for cleaning and film application, extending the distance the glass moves.

[0046] In the cleaning mechanism 3, the height of the upper abutment plate 35 and the cleaning pad 36 is adjusted by the connecting rod 33 inside the mounting frame 31 according to the thickness of the glass, thereby adjusting the distance between the two cleaning pads 36, keeping the upper and lower cleaning pads 36 abutting against the two sides of the glass as it moves, and cleaning and removing dust from both sides of the glass.

[0047] Furthermore, after a period of use, the cleaning pad 36 can be disassembled, replaced, and maintained via the connecting rod 33 and nut 34 to keep the cleaning pad 36 clean and facilitate simultaneous cleaning and dust removal on both sides of the glass.

[0048] A film applicator 5 is installed on the rear side of the cleaning mechanism 3, and the position of the film applicator 5 is adjusted by the drive moving mechanism 4. Therefore, the film roll 52 is wound around the surface of the rotating rod 51. The rotating rod 51 is rotatably installed between two drive plates 53. The drive plates 53 are driven to be installed inside the support frame 41 by the drive rod 43 and the second guide rod 42.

[0049] Therefore, the first motor 44 and the second motor 56 are controlled by an external controller connected by wires. According to the thickness of the glass, the two first motors 44 are selected with the same model and maintain the same speed. The two first motors 44 run synchronously, driving the two drive rods 43 to rotate synchronously, and driving the drive plate 53 to move through the drive hole 57, so that the drive plates 53 at both ends of the rotating rod 51 move synchronously, thereby driving the two film rolls 52 to move up and down synchronously.

[0050] As the glass is pushed to the top of the mounting groove 15 by the first push plate 26 and the second push plate 27, the upper and lower film rolls 52 abut against and adhere to the sides of the glass. At the same time, the second motor 56 drives the second gear 55 to rotate and meshes with the first gear 54 to rotate. The two second motors 56 are of the same model and maintain the same speed. The two second motors 56 run synchronously, thereby driving the two rotating rods 51 and the film rolls 52 to rotate synchronously and in opposite directions.

[0051] Therefore, both sides of the glass can be simultaneously coated with film, and the glass can be driven to move backwards towards the film coating table 11 by the abutting friction force, so that the glass can complete the simultaneous coating of the upper and lower sides while moving out of the top of the mounting groove 15. Afterwards, the film roll 52 after the film coating of both sides of the glass is completed is cut by a cutting blade or other structure, and the subsequent glass is coated again.

[0052] As the film roll 52 applies film to both sides of the glass, its diameter gradually decreases. At the same time, the first motor 44 operates and drives the drive plate 53 to move through the drive rod 43 and drive hole 57, so that the two film rolls 52 gradually approach each other and always abut against and adhere to both sides of the glass, thereby keeping the film on both sides of the glass in tight contact and reducing the occurrence of air bubbles.

[0053] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
