Description

Technical Field

[0001] The present invention relates to the technical field of laminated glass production, and particularly to a laminated glass production line. Background Art

[0002] Laminated glass is a kind of safety glass composed of multiple layers of glass and an intermediate layer. Its core feature is to combine glass with polymer materials through a special lamination process, with characteristics of safety, strength and multi-functionality.

[0003] The following problems exist in the actual production process of existing laminated glass:

[0004] In the application of curtain wall projects, the traditional trimming process of the adhesive film adopts a pure manual operation mode. Operators need to use a handheld blade tool to perform fine cutting along the outer edge of the laminated glass to remove the redundant adhesive film layer. Especially when applied to the processing of non-standard geometric glass components such as hexagons, due to the complex trimming requirements caused by the special-shaped structural features, operators have to repeatedly adjust the spatial posture of the components to meet the multi-angle cutting requirements. During the processing of a single special-shaped glass product, on average, more than 6 flipping and positioning operations need to be performed. Such a high-frequency station adjustment not only significantly affects the operation efficiency, but also poses a double test on the physical strength and operation accuracy of the operators, fully exposing the technical limitations of the traditional process in dealing with the processing of complex components. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems of low operation accuracy and low work efficiency in the existing manual trimming operation, and to propose a laminated glass production line.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A laminated glass production line includes a lamination table and a workbench. An X-shaped chute is opened on the workbench. Four sliding plates are slidably arranged in the X-shaped chute. A contact column for positioning and installing glass is fixedly arranged on the upper surfaces of the four sliding plates;

[0008] A telescopic frame is fixedly connected to the workbench. A multi-dimensional adjustment component is fixedly arranged on the frame. A vision module and a cutting blade are installed on the frame through the multi-dimensional adjustment component.

[0009] Preferably, an installation cavity is opened on the workbench. A first motor is fixedly installed in the installation cavity. The output end of the first motor is fixedly connected to an installation shaft extending into the X-shaped chute. A driving gear is fixedly sleeved on the installation shaft. A driven rack meshing with the driving gear is fixedly connected to the sliding plate.

[0010] Preferably, a pressure sensor is arranged on the side of the contact column that abuts against the glass.

[0011] Preferably, the frame is composed of two U-shaped plates and three sleeve plates. The upper end of the U-shaped plate is slidably connected to one of the sleeve plates, and the lower end of the U-shaped plate is slidably connected to the other two sleeve plates fixed to the workbench.

[0012] Preferably, a telescopic rod is fixedly connected between the two sliding plates, and a connecting rod is fixedly connected between the telescopic rod and the frame.

[0013] Preferably, the multi-dimensional adjustment assembly includes:

[0014] A first air cylinder fixedly installed on the frame;

[0015] A second motor driven by the first air cylinder to move up and down;

[0016] A connecting frame driven by the second motor to rotate;

[0017] A slider sliding on the connecting frame;

[0018] A second air cylinder installed on the connecting frame and fixedly connected to the slider;

[0019] A fourth motor fixed on the slider;

[0020] A first moving slide driven by the fourth motor to rotate;

[0021] A third motor driven by the first moving slide to move horizontally;

[0022] A second moving slide driven by the third motor to rotate;

[0023] A third moving slide driven by the second moving slide to move horizontally;

[0024] A fifth motor driven by the third moving slide to move horizontally and fixedly connected to the vision module and the cutting blade.

[0025] Preferably, a chute for slidably sleeving the slider is provided on the connecting frame.

[0026] Preferably, a guiding long groove is provided on the side wall of the frame, and a telescopic sleeve plate fixedly connected to the second motor is slidably sleeved in the guiding long groove.

[0027] Preferably, the second air cylinder and the first moving slide are distributed in a V shape, and the second air cylinder and the first moving slide are arranged corresponding to each other up and down.

[0028] Preferably, the second moving slide and the third moving slide are distributed in a cross shape, and the second air cylinder and the first moving slide are arranged corresponding to each other up and down.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] 1. The present invention uses four groups of cylindrical contact columns to make dynamic contact with the glass edge, realizes rapid positioning of the workpiece through high-precision synchronous moving towards each other, and the end points of the movement trajectories of each contact column are precisely calibrated to coincide with the origin of the workbench coordinate system, ensuring the precise matching of the geometric center of the laminated glass and the rotation center of the workbench. Moreover, a unique adaptive point contact mechanism is formed by the cylindrical surface of the contact column and the glass, and the positioning requirements of polygonal and special-shaped glass substrates can be compatible through the dynamic adjustment of the contact points.

[0031] 2. The present invention integrates high-precision pressure sensors in the core pressure-bearing area of the contact column, and real-time monitors the dynamic changes of the clamping force through a multi-dimensional mechanical feedback system. This intelligent monitoring system adopts the closed-loop control principle. When it detects that the pressing intensity is close to the critical value of material yield, it can automatically trigger the overload protection mechanism to precisely control the clamping force within the preset safe threshold range. The risk of micro-crack propagation caused by stress concentration in traditional rigid clamping is effectively avoided through the adaptive pressure compensation algorithm.

[0032] 3. By integrating a high-precision vision module, the system can real-time obtain the geometric parameters and contour features of the glass product, and transmit the digital specification data to the multi-dimensional adjustment component through the industrial bus. This multi-dimensional adjustment component conducts three-dimensional space modeling on the cutting path based on the motion control algorithm, and thus drives the cutting blade to complete precise cutting of complex shapes, enabling a single production line to be compatible with processing more than 20 specifications of laminated glass products, significantly improving the equipment utilization rate and reducing the production line switching cost.

Specific implementation mode

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0041] Refer to Figures 1-6 , a laminated glass production line, including a laminated glass table 1 and a workbench 2. An X-shaped chute 3 is opened on the workbench 2. Four sliding plates 4 are slidably arranged in the X-shaped chute 3. Abutting columns 5 for positioning and installing glass are fixedly arranged on the upper surfaces of the four sliding plates 4. The freedom degree of the sliding plates 4 is restricted by the X-shaped chute 3, forcing them to move along a predetermined trajectory. It should be noted that: the end points of the movement trajectories of the respective sliding plates 4 are precisely calibrated to coincide with the origin of the coordinate system of the workbench 2. Furthermore, it is ensured that the end points of the movement trajectories of the abutting columns 5 are precisely calibrated to coincide with the origin of the coordinate system of the workbench 2. And the abutting column 5 is of a circular columnar structure. Therefore, when the cylindrical surface of the abutting column 5 contacts the glass, it is a point contact. Through the dynamic adjustment of the contact points, the positioning requirements of polygonal and shaped glass substrates can be compatible, which helps to improve the applicability of the laminated glass production line. A pressure sensor 15 is arranged on the side of the abutting column 5 that abuts against the glass. An installation cavity 10 is opened on the workbench 2. A first motor 11 is fixedly installed in the installation cavity 10. The output end of the first motor 11 is fixedly connected with an installation shaft 12 extending into the X-shaped chute 3. A driving gear 13 is fixedly sleeved on the installation shaft 12. A driven rack 14 meshing with the driving gear 13 is fixedly connected to the sliding plate 4. It should be noted that: the pressure sensor 15 outputs digital signals through EtherCAT and communicates with the controller of the first motor 11. The dynamic change of the clamping force of the abutting column 5 on the glass is monitored in real time through the pressure sensor 15. When it is detected that the pressure application intensity is close to the critical value of material yield, the overload protection mechanism is automatically triggered. The first motor 11 controls the clamping force generated by the abutting column 5 through the gear-rack mechanism, so that the clamping force is controlled within a preset safety threshold range. The risk of microcrack propagation caused by stress concentration in traditional rigid clamping is effectively avoided through the adaptive pressure compensation algorithm.

[0042] A telescopic frame 6 is fixedly connected to the workbench 2. The frame 6 is composed of two U-shaped plates and three sleeve plates. The upper end of the U-shaped plate is slidably connected to one of the sleeve plates, and the lower end of the U-shaped plate is slidably connected to the other two sleeve plates fixedly connected to the workbench 2. A telescopic rod 16 is fixedly connected between the two sliding plates 4. A connecting rod 17 is fixedly connected between the telescopic rod 16 and the frame 6. The change of the frame 6 is adapted by the telescopic property of the telescopic rod 16. At the same time, the frame 6 is synchronously driven by the connecting rod 17 to perform structural expansion and contraction, so as to provide sufficient working space for glass of different sizes and specifications. A multi-dimensional adjustment component 7 is fixedly arranged on the frame 6. The frame 6 is provided with a vision module 8 and a cutting blade 9 through the multi-dimensional adjustment component 7. The cutting blade 9 is a cemented carbide blade. The movement track of the cutting blade 9 is adjusted through the multi-dimensional adjustment component 7. Compared with frequently starting and stopping the blade by rotating the glass, the dynamic adjustment of the blade track can directly switch the cutting path through the multi-dimensional adjustment component 7, saving the waiting time of mechanical rotation. At the same time, it avoids the stress concentration easily generated at the edge due to the friction between the glass and the fixture during the rotation process. The fixed glass + blade track adjustment can avoid such mechanical contact damage, and the depth of microcracks is reduced by more than 50%. At the same time, there is a risk of debris flying when the glass rotates at high speed. In the present invention, the glass is fixed by the abutting column 5, which can greatly reduce the probability of accidental contact by personnel or equipment collision accidents. The multi-dimensional adjustment component 7 includes a first cylinder 701, a second motor 702, a connecting frame 703, a slider 704, a second cylinder 705, a first moving slide 706, a third motor 707, a second moving slide 708, a third moving slide 709 and a fifth motor 710. The settings of each component are as follows:

[0043] The first cylinder 701 is fixedly installed on the frame 6. The second motor 702 is driven by the first cylinder 701 to move up and down. The height position of the cutting blade 9 is adjusted by the first cylinder 701. A guiding long groove is formed on the side wall of the frame 6. A telescopic sleeve plate fixedly connected with the second motor 702 is slidably sleeved in the guiding long groove. The telescopic property of the telescopic sleeve plate is used to adapt to the structural change of the frame 6. At the same time, the degree of freedom of the telescopic sleeve plate is restricted by the guiding long groove, forcing it to move along a predetermined track. The guiding long groove bears the gravity of the telescopic sleeve plate and external pressure. The connecting frame 703 is driven by the second motor 702 to rotate. The slider 704 slides on the connecting frame 703. A chute for slidably sleeving the slider 704 is formed on the connecting frame 703. The second cylinder 705 is installed on the connecting frame 703 and fixedly connected with the slider 704. The second cylinder 705 is used to control the cutting blade 9 to move along the right inclined edge of the glass. At the same time, the operating track of the second cylinder 705 is adjusted by the second motor 702, so that the cutting blade 9 can adapt to the right inclined edges of glasses with different angles. The fourth motor 711 is fixed on the slider 704. The first moving slide 706 is driven by the fourth motor 711 to rotate. The second cylinder 705 and the first moving slide 706 are distributed in a V shape, and the second cylinder 705 and the first moving slide 706 are arranged vertically corresponding to each other. The first moving slide 706 is used to control the cutting blade 9 to move along the left inclined edge of the glass. At the same time, the operating track of the first moving slide 706 is adjusted by the fourth motor 711, so that the cutting blade 9 can adapt to the left inclined edges of glasses with different angles. The third motor 707 is driven by the first moving slide 706 to move horizontally. The second moving slide 708 is driven by the third motor 707 to rotate. The third moving slide 709 is driven by the second moving slide 708 to move horizontally. The second moving slide 708 and the third moving slide 709 are distributed in a cross shape. The second moving slide 708 and the third moving slide 709 are used to control the cutting blade 9 to move along the xy-axis direction. At the same time, the positions of the second moving slide 708 and the third moving slide 709 are adjusted by the third motor 707, so that the setting directions of the second moving slide 708 and the third moving slide 709 always correspond to the original xy-axis of the workbench 2, so that the cutting blade 9 can cut the straight edge of the glass. The fifth motor 710 is driven by the third moving slide 709 to move horizontally. The output end of the fifth motor 710 is fixedly connected with a vision module 8 and a cutting blade 9 through a plate. The cutting direction of the cutting blade 9 is controlled by the fifth motor 710, so as to adapt to the cutting requirements of the cutting blade 9 for different sides of the glass. It should be noted that: the moving slides are all composed of a C-shaped bracket, a motor, a lead screw and a nut.

[0044] The functional principle of the present invention can be elaborated through the following operation modes:

[0045] Place the glass on the workbench 2, start the second motor 702 to rotate, the first motor 11 drives the mounting shaft 12 to rotate, the mounting shaft 12 drives the driving gear 13 to rotate, the driving gear 13 drives the driven rack 14 to move horizontally, and drives the four sliding plates 4 to move synchronously towards each other through the driven rack 14. The sliding plate 4 realizes the rapid positioning of the glass through the contact post 5;

[0046] Detect the geometric parameters and contour features of the glass product through the vision module 8, and transmit the digital specification data to the multi-dimensional adjustment component 7 through the industrial bus. Start the second motor 702 to drive the connecting frame 703 to adjust the angle, and start the fifth motor 710 to control the first moving slide 706 to adjust the angle, so as to correspond to the hypotenuse of the glass product. Start the fourth motor 711 to adjust the orientation of the second moving slide 708 and the third moving slide 709;

[0047] Control the height position of the cutting blade 9 through the first cylinder 701, control the cutting blade 9 to cut and remove the adhesive film at the hypotenuse position of the glass through the second cylinder 705 and the first moving slide 706, control the cutting blade 9 to cut and remove the straight edge of the glass through the second moving slide 708 and the third moving slide 709, and at the same time control the cutting direction of the cutting blade 9 through the fourth motor 711, so that the production line can adapt to glass of different specifications and sizes.

[0048] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
