Description

Technical Field

[0001] The invention relates to the field of glass plate processing, in particular to a PVB intermediate film filling device for automobile glass plates. Background Art

[0002] The PVB interlayer filling device for automobile glass panels is one of the key equipment in the manufacturing process of automobile glass. PVB interlayer is a material with high transparency, high toughness and good adhesion. It is widely used in automobile safety glass. As an interlayer between two layers of glass, it can play a bonding role when the glass is broken, prevent fragments from splashing, and protect the safety of passengers. With the rapid development of the automobile industry and the continuous improvement of consumers' requirements for safety performance, the safety performance of automobile glass has become the focus of attention of manufacturers. Therefore, higher requirements are put forward for the filling process and equipment of PVB interlayer. The emergence of the PVB interlayer filling device for automobile glass panels is to meet this market demand. It can achieve precise bonding between PVB interlayer and glass panels, improve the safety performance and overall quality of automobile glass; in traditional automobile glass panel PVB interlayer filling technology, most of them rely on manual operation or semi-automatic equipment. There are many disadvantages in manual operation. For example, in the process of clamping the glass panel, it is difficult to ensure that the force and position of each clamping are accurate and consistent due to human factors, which may cause the glass panel to be displaced or damaged during subsequent processing, affecting the quality stability of the product. Moreover, manual operation is inefficient and cannot meet the large-scale and high-efficiency production needs of the modern automobile industry. Although semi-automatic equipment has improved production efficiency to a certain extent, it often requires complex manual adjustments when processing glass plates of different thicknesses, and the adjustment accuracy is limited, which is prone to poor adaptation. In the cleaning and pre-pressing process, traditional technology is difficult to achieve uniform and thorough cleaning and preheating and pressing of the glass plate surface and PVB interlayer, resulting in unsatisfactory bonding between the PVB interlayer and the glass plate, and prone to quality problems such as bubbles and debonding, which seriously affect the optical properties, strength and service life of the automotive glass plate, reduce the overall safety and comfort of the car, and also increase production costs and after-sales maintenance risks. For this reason, we propose a PVB interlayer filling device for automotive glass plates. Summary of the invention

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a PVB interlayer filling device for automobile glass panels, which has the following beneficial effects:

[0022] 1. Efficient automated operation

[0023] Automated clamping:

[0024] The center horizontal plate is driven to rotate by servo motor 2, and then the horizontal plate is pushed by the lever arm to realize automatic clamping of the glass plate. This automatic operation reduces the complexity and labor intensity of manual operation and improves production efficiency.

[0025] For example, in the mass production of automotive glass panels, each glass panel can be positioned and clamped quickly and accurately to ensure smooth subsequent processing.

[0026] Automated processing flow:

[0027] Driven by a servo motor, the processing turntable can automatically move the glass plate from one processing station to the next, achieving seamless connection between different processing steps.

[0028] For example, after the glass sheet is clamped, it can automatically move to the clean pre-pressing structure position without manual handling, reducing time waste in the production process.

[0029] 2. Precise glass plate processing

[0030] Adapt to different thickness of glass plates:

[0031] The lifting structure can accurately adjust the height of the clamping horizontal plate so that it can adapt to glass plates of different thicknesses.

[0032] This is a great advantage in actual production, because automotive glass panels may have different specifications and thicknesses. For example, whether it is a thinner side window glass panel or a thicker front windshield glass panel, the device can handle it well, avoiding the problem of changing equipment or making complex adjustments due to different glass panel thicknesses. The most important thing is that through the upgradeable clamping horizontal plate, the top of the clamping horizontal plate can be adjusted to a height lower than the top of the glass panel of different thicknesses. When the PVB interlayer is subsequently glued to the upper surface of the first glass panel, the clamping horizontal plate will not interfere with the gluing operation.

[0033] Precise cleaning and pre-pressing:

[0034] The reciprocating transverse movement mechanism and the blowing roller brush mechanism in the cleaning and pre-pressing structure can accurately clean and pre-press the surface of the glass plate and the PVB interlayer.

[0035] For example, the reciprocating cross plate can reciprocate horizontally under the drive of the toothless gear and servo motor three, ensuring that the cleaning brush roller and the air jet nozzle can cover the entire surface of the glass plate, making the cleaning and preheating more uniform and thorough, and providing a guarantee for the good bonding of the PVB interlayer.

[0036] 3. High-quality PVB interlayer filling

[0037] Ensure good adhesion of PVB interlayer:

[0038] When processing the PVB interlayer film, the rolling action of the cleaning brush roller and the continuous preheating of the air jet nozzle can make the PVB interlayer film fit more smoothly on the glass plate and the viscosity is evenly distributed.

[0039] This helps to improve the composite quality of automotive glass panels and prevent quality problems such as debonding or bubbles in the PVB interlayer during use, thereby ensuring the safety and reliability of automotive glass.

[0040] Good cleaning effect:

[0041] The outer surface of the cleaning brush roller is made of ultra-fine fiber dust-free cloth, which can effectively remove dust and impurities on the surface of the glass plate and the surface of the PVB interlayer.

[0042] In the production of automotive glass, the cleanliness of the surface is crucial to the optical properties and bonding quality of the glass. The cleaning measures of this device can ensure that the glass plate and PVB interlayer meet a high cleanliness standard before bonding, thus improving the quality of the final product.

DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See also Figure 1-8 A PVB interlayer film filling device for automobile glass plates comprises a processing table 1, a processing turntable 2 is rotatably installed at the center of the processing table 1, and a servo motor 1 for driving the processing turntable 2 to rotate is fixedly installed below the processing table 1 corresponding to the processing turntable 2, and four groups of station grooves 3 located on four sides and symmetrically arranged at the center are opened on the processing turntable 2;

[0054] Also includes:

[0055] A glass plate clamping structure is arranged in each group of station grooves 3, the glass plate clamping structure is used to clamp the first glass plate to be adhered with the PVB interlayer, and the glass plate clamping structure includes two groups of transverse plates 10 and a clamping transverse plate 11 on both sides for clamping the first glass plate;

[0056] A lifting structure is arranged between the transverse plates 10 and the clamping horizontal plate 11 on both sides of the glass plate clamping structure, and the lifting structure is used to control the height of the clamping horizontal plate 11 to be suitable for clamping glass plates of different thicknesses;

[0057] A cleaning pre-pressing structure is provided on one side of the processing table 1, and the cleaning pre-pressing structure can clean the glass plate after being fixed and clean and preheat and press the PVB intermediate film after being adhered.

[0058] A supporting cross plate 4 is fixedly installed at the center of each group of workstation grooves 3 on the top of the processing turntable 2, and the supporting cross plate 4 spans the midpoints of the two side edges of the workstation groove 3; its function is not only to provide support when the glass plate is initially placed, but also to ensure that the glass plate maintains a stable position in the workstation groove 3 during the entire processing process, preventing the glass plate from shifting due to movement or vibration during the processing, thereby ensuring the accuracy of subsequent clamping, cleaning, pre-pressing and PVB interlayer film filling operations.

[0059] The glass plate clamping structure also includes a central transverse plate 7, a servo motor 2 8 and a lever arm 9. The processing turntable 2 is rotatably mounted at the center of the bottom inner wall of each group of station grooves 3, and a servo motor 2 8 is embedded and mounted inside the processing turntable 2 just below the center of each group of station grooves 3. The output shaft of the servo motor 2 8 passes through the bottom inner wall of the station groove 3 and is fixedly connected to the center of the central transverse plate 7. The central transverse plate 7 is inclined and both ends of the central transverse plate 7 are hinged with a lever arm 9. The lever arm 9 at both ends of the central transverse plate 7 is inclined and symmetrical about the center, and the free ends of the two groups of lever arm 9 are hinged at the bottom center of each side transverse plate 10. The servo motor 2 8 serves as a power source to drive the central transverse plate 7 to rotate. The inclined design of the central transverse plate 7 and the hinged connection with the lever arm 9 can convert the rotational motion of the motor into the telescopic motion of the lever arm 9, thereby realizing the pushing effect on the transverse plates 10 on both sides, so that it can accurately clamp the glass plate.

[0060] Two groups of parallel limiting transverse grooves 13 are provided on the bottom inner wall of the work station groove 3, and the bottom ends of the two side transverse plates 10 in each group of glass plate clamping structure are fixedly connected with limiting blocks 12 that are slidably engaged with the two groups of limiting transverse grooves 13, and are arranged on the bottom inner wall of the work station groove 3, providing a precise guide path for the movement of the transverse plate 10, limiting the moving direction of the transverse plate 10, and ensuring that the transverse plate 10 can only move in a straight line along the groove, thereby ensuring that the transverse plates 10 on both sides can accurately approach or move away from each other, thereby achieving precise clamping of the glass plate.

[0061] The central horizontal plate 7 and the lever arm 9 in the glass plate clamping structure are both located below the supporting horizontal plate 4, and the top ends of the two side horizontal plates 10 in the glass plate clamping structure are flush with the top ends of the rectangular frame 6, and rubber sheets 14 are fixedly installed on the side walls of the two side horizontal plates 10 close to each other; the setting of the rubber sheet 14 has multiple functions. On the one hand, it can increase the friction between the horizontal plate 10 and the glass plate, prevent the glass plate from sliding during the clamping process, and ensure the firmness of the clamping; on the other hand, the rubber sheet is relatively soft in texture, which can avoid scratching or damage to the surface of the glass plate when clamping it, and protect the surface quality of the glass plate.

[0062] The lifting structure arranged between the transverse plates 10 and the clamping cross plates 11 on both sides of the glass plate clamping structure includes right-angled triangular blocks 15, extended rectangular cavities 16, electric telescopic rods 17 and connecting rods 18. The interior of the transverse plate 10 is provided with a rectangular cavity with the sliding clamping cross plate 11, and the corresponding rectangular cavities 16 are provided on both sides of the interior of the transverse plate 10. The two ends of the bottom outer wall of the corresponding clamping cross plate 11 in the transverse plate 10 are slidably filled with right-angled triangular blocks 15, and the two groups of right-angled triangular blocks 15 in the transverse plate 10 are symmetrical to each other, and the end sides of the two groups of right-angled triangular blocks 15 facing away from each other are aligned up and down with the two end sides of the clamping cross plate 11, and the tops of the two groups of right-angled triangular blocks 15 and the bottom ends of the clamping cross plate 11 are fitted and connected. The glass plate clamping structure is symmetrically inclined, and the ends of the two groups of right-angled triangle blocks 15 that face away from each other are the highest ends. The bottom inner wall of the extended rectangular cavity 16 is flush with the bottom inner wall of the rectangular cavity, and the top inner wall of the extended rectangular cavity 16 is flush with the top of the right-angled triangle block 15. The side walls of the transverse plates 10 on both sides that face away from each other are fixedly installed with two groups of symmetrical electric telescopic rods 17, and the ends of the two groups of electric telescopic rods 17 that face away from each other are piston ends. A through transverse groove communicating with the rectangular cavity and the extended rectangular cavity 16 is provided on the side of the transverse plate 10 corresponding to the electric telescopic rod 17. The piston end sides of the two groups of electric telescopic rods 17 are fixedly connected to the right-angled triangle blocks 15 on both sides of the transverse plate 10 with connecting rods 18 that are slidably engaged in the through transverse groove.

[0063] The lifting structure arranged between the transverse plates 10 and the clamping horizontal plate 11 on both sides of the glass plate clamping structure also includes an inclined T-slot 19 and a T-block 20. The inclined top of the right-angled triangle block 15 is provided with an open inclined T-slot 19. The bottom of the clamping horizontal plate 11 is fixed with an integrated T-block 20 on both sides. The T-blocks 20 on both sides of the bottom of the clamping horizontal plate 11 are slidably engaged in the inclined T-slots 19 opened by the right-angled triangle blocks 15 on both sides. The bottom horizontal plate part of the T-block 20 is in an inclined shape that fits the inclined top of the right-angled triangle block 15. The electric telescopic rod 17 is the power part of the lifting structure and is connected to the right-angled triangle block 15 through the connecting rod 18. When the electric telescopic rod 17 is extended and retracted, it can drive the right-angled triangle block 15 to move in the extended rectangular cavity 16. Due to the special inclined connection between the right-angled triangle block 15 and the bottom of the clamping cross plate 11, the movement of the right-angled triangle block 15 will be converted into the up and down movement of the clamping cross plate 11 in the transverse plate 10, thereby realizing the precise adjustment of the height of the clamping cross plate 11.

[0064] The cleaning pre-pressing structure includes a reciprocating transverse movement mechanism and a blowing roller brush mechanism. The blowing roller brush mechanism is arranged below the reciprocating transverse movement mechanism. The reciprocating transverse movement mechanism includes a reciprocating transverse plate 22, a toothless gear 24, a servo motor 25, a pulley 26 and a belt. Two groups of support columns 5 are fixedly installed on the processing table 1 near one side, and the tops of the two groups of support columns 5 are fixedly connected with a rectangular frame 6 located directly above a group of supporting transverse plates 4. A through rectangular hole 21 is opened in the middle of the two ends of the rectangular frame 6, and the rectangular frame 6 is slidably connected with a horizontal reciprocating transverse plate 22 through the rectangular holes 21 at both ends, and the reciprocating transverse plate 22 is located directly above the center of the supporting transverse plate 4. The middle of the top of the rectangular frame 6 is fixed with transverse base plates 23 located on both sides above the reciprocating transverse plate 22, and the transverse base plates 23 on both sides of the reciprocating transverse plate 22 are fixedly installed. The bottom sides of the ends close to each other are rotatably mounted with toothless gears 24, and only half of the gear teeth are arranged on the outer annular surfaces of the toothless gears 24 on both sides, and the gear teeth of the toothless gears 24 on both sides face the same direction, and the two sides of the reciprocating horizontal plate 22 are provided with gear tooth grooves 27 that can mesh with the toothless gears 24 on both sides, and the spacing distance between the horizontal base plates 23 on both sides is greater than the width of the reciprocating horizontal plate 22, and the top ends of the horizontal base plates 23 on both sides are rotatably mounted with pulleys 26 fixedly connected to the toothless gears 24, and a belt is connected between the pulleys 26 on both sides, and a servo motor 3 25 located directly above the pulley 26 is fixedly mounted on one side of the horizontal base plate 23, and the output shaft of the servo motor 3 25 faces downward and is fixedly connected to the center of the pulley 26, and the air blowing roller brush mechanism is arranged at the bottom center of the reciprocating horizontal plate 22.

[0065] The blowing roller brush mechanism includes an electric cylinder 28, a connecting base frame 29, a cleaning brush roller 30 and an air jet nozzle 31. The electric cylinder 28 located just above the center of the supporting horizontal plate 4 is fixedly installed at the bottom center of the reciprocating horizontal plate 22, and the bottom piston shaft of the electric cylinder 28 is fixedly installed with a connecting base frame 29 parallel to the supporting horizontal plate 4, and the connecting base frame 29 is perpendicular to the reciprocating horizontal plate 22. Two groups of parallel and spaced cleaning brush rollers 30 are rotatably installed in the connecting base frame 29. The air jet nozzle 31 is fixedly installed in the middle of the cleaning brush rollers 30 on both sides of the connecting base frame 29, and a through groove is opened at the top of the connecting base frame 29. The air jet nozzle 31 is fixedly connected to a ventilation hose passing through the through groove, and the other end of the ventilation hose is connected to the output end of the low-temperature hot air blower.

[0066] The outer surface of the cleaning brush roller 30 is wrapped with a microfiber dust-free cloth, the air jet nozzle 31 is the same length as the cleaning brush roller 30, and the air outlet at the bottom of the cleaning brush roller 30 is a cone-shaped one that is narrow at the top and wide at the bottom, and the bottom end of the air jet nozzle 31 is higher than the bottom end of the cleaning brush roller 30; the microfiber dust-free cloth has good cleaning ability and low dust generation characteristics, and can effectively remove dust, impurities and other pollutants on the surface of the glass plate, while not leaving fiber residues on the surface of the glass plate, thereby ensuring the cleanliness of the surface of the glass plate. The cone-shaped design of the air outlet at the bottom of the cleaning brush roller 30 allows the ejected low-temperature hot air to act more concentratedly on the surface of the glass plate, thereby improving the preheating efficiency and cleaning effect. The design that the bottom end of the air jet nozzle 31 is higher than the bottom end of the cleaning brush roller 30 can avoid the air jet from directly impacting the cleaning brush roller 30, and prevent the cleaning brush roller 30 from being deformed or damaged due to excessive airflow impact, and is also conducive to the uniform distribution of hot air on the surface of the glass plate, further improving the quality of cleaning and pre-pressing.

[0067] Working principle: In the initial state, the servo motor 28 is in a stationary state, the central horizontal plate 7 remains horizontal, the lever arm 9 is in a retracted state, and the two side transverse plates 10 are on both sides of the workstation groove 3. When it is necessary to clamp the glass plate, first place the first glass plate on the supporting horizontal plate 4, and then start the servo motor 28 to drive the central horizontal plate 7 to rotate. The rotation of the central horizontal plate 7 causes the lever arm 9 at both ends to tilt synchronously, pushing the two side transverse plates 10 to move along the limiting transverse groove 13 toward the center of the supporting horizontal plate 4. The two side transverse plates 10 approach each other, and the first glass plate is clamped by the rubber sheet 14. When it is necessary to clamp glass plates of different thicknesses, the lifting structure is started. The two sets of electric telescopic rods 17 on the two side transverse plates 10 are synchronously started to extend and retract, and the right-angle triangle block 15 is pushed to move in the extended rectangular cavity 16 through the connecting rod 18. The movement of the right-angled triangle block 15 drives the clamping horizontal plate 11 to move up and down in the transverse plate 10 through the inclined T-slot 19 and the T-block 20, thereby adjusting the height of the clamping horizontal plate 11 to adapt to glass plates of different thicknesses. In this way, the top of the clamping horizontal plate 11 can be adjusted to a height lower than the top of the glass plates of different thicknesses. When the PVB interlayer film is subsequently glued to the upper surface of the first glass plate, the clamping horizontal plate 11 will not interfere with the gluing operation.

[0068] When a group of glass plate clamping structures completes the clamping of the glass plate, the servo motor starts and drives the processing turntable 2 to rotate. The processing turntable 2 rotates to move the workstation groove 3 that has clamped the glass plate to the next working position, such as the position of the cleaning pre-pressing structure. The servo motor three 25 is in a stationary state, the toothless gear 24 is stationary, and the reciprocating cross plate 22 is located at one end of the rectangular frame 6. When the glass plate needs to be cleaned and pre-pressed, the servo motor three 25 is started to drive the pulley 26 to rotate. The pulley 26 drives the toothless gears 24 on both sides to rotate synchronously through the belt. When the gear teeth of the toothless gear 24 are engaged with the gear tooth grooves 27 of the reciprocating cross plate 22, the reciprocating cross plate 22 is pushed to reciprocate horizontally in the rectangular frame 6. The electric cylinder 28 is in a retracted state, and the cleaning brush roller 30 and the jet nozzle 31 are located at a higher position. When the reciprocating cross plate 22 moves above the glass plate, the electric cylinder 28 is started to push the connecting base frame 29 to move downward. The connecting base frame 29 drives the cleaning brush roller 30 and the air jet nozzle 31 to descend, so that the cleaning brush roller 30 contacts the surface of the glass plate. The cleaning brush roller 30 cleans the surface of the glass plate during the rotation process, and the air jet nozzle 31 sprays low-temperature hot air to preheat and clean the glass plate. The reciprocating movement of the reciprocating horizontal plate 22 ensures that the cleaning brush roller 30 and the air jet nozzle 31 can cover the entire surface of the glass plate to complete the cleaning and pre-pressing work. The workflow of the entire device starts from the glass plate clamping structure, and first clamps the first glass plate. Then the processing turntable 2 rotates to move the station for clamping the glass plate to the cleaning pre-pressing structure position. The cleaning pre-pressing structure cleans and pre-presses the glass plate to ensure that the surface of the glass plate is clean and preheated, in preparation for the subsequent filling and bonding of the PVB interlayer. After that, the PVB interlayer is glued to the first glass plate that has been cleaned, and the cleaning pre-pressing structure is operated again to process the PVB interlayer. While the cleaning brush roller 30 cleans the PVB interlayer, the weight and rotation of the cleaning brush roller 30 itself can produce a certain rolling effect on the PVB interlayer. This rolling effect can make the PVB interlayer fit more smoothly on the glass plate. The jet nozzle 31 continuously sprays low-temperature hot air to further preheat the PVB interlayer during the rolling process to ensure that its viscosity is evenly distributed. The cleaning brush roller 30 continues to rotate to further clean the surface of the PVB interlayer, remove tiny impurities that may remain in the previous operation, ensure that the surface of the PVB interlayer is clean, and facilitate the subsequent pressing of the second glass plate.

[0069] Repeat the above steps to process multiple glass plates in sequence, and finally complete the filling work of the PVB interlayer film of the automobile glass plate.
