Description

Technical Field

[0001] The present invention relates to the technical field of glass polishing, and in particular to a glass intelligent processing production line. Background Art

[0002] During the grinding process, curved glass needs stable support to prevent it from moving. At the same time, multiple suction cups are used for support. Compared with flat glass, it is more prone to stress concentration, which causes the curved glass to break due to stress concentration during the grinding process. After the glass is transported to the designated grinding position, the position of the glass needs to be adjusted through sensors and actuators. After the glass enters the designated position, it is positioned and polished, and the efficiency is not high enough. Summary of the invention

[0003] The present invention provides a glass intelligent processing production line, which solves the disadvantage in the prior art that the support and positioning of the curved glass cannot be performed synchronously after being transmitted to a specified position.

[0004] The present invention provides the following technical solutions:

[0005] A glass intelligent processing production line includes a first transmission mechanism for transmitting glass to a grinding station, wherein a limiting mechanism for adjusting the position of the glass is installed on the first transmission mechanism, and the lateral position of the glass when entering the grinding station is adjusted by the limiting mechanism;

[0006] The polishing station is provided with a support mechanism fixed to the ground, a second transmission mechanism with adjustable height, and a polishing mechanism. The support mechanism, the second transmission mechanism, and the polishing mechanism are arranged to avoid each other. The second transmission mechanism is installed with a sensor. The sensor detects that the glass reaches a predetermined position and drives the second transmission mechanism to stop rotating, and at the same time drives the lifting mechanism to lower the second transmission mechanism and the polishing mechanism. The support mechanism is provided with a curved surface adapted to the lower surface of the glass. The glass is pressed onto the support mechanism after the second transmission mechanism descends. The polishing mechanism polishes the upper surface of the glass after it descends to the predetermined position.

[0007] As a further improvement of the above scheme.

[0008] Preferably, the second transmission mechanism includes a frame and rollers between the frames driven to rotate by a motor, a supporting mechanism is installed in the gap between the rollers of the second transmission mechanism, the supporting mechanism includes a longitudinal beam located in the gap, the upper surface of the longitudinal beam is provided with an arc adapted to the concave arc surface on the lower side of the glass, and the longitudinal beam is fixedly connected to the ground through a column; the curved surface design can fit the shape of the glass, disperse local pressure, and reduce the risk of breakage; the supporting bent plate in the flexible glass flipping device adopts a spring steel plate wrapped with a rubber sleeve, which not only provides elastic support but also avoids scratching the glass; the longitudinal beam is fixedly connected to the ground through a column, thereby enhancing the rigidity of the supporting mechanism.

[0009] Preferably, the lifting mechanism is a scissor lift driven by a motor, the bottom of the scissor lift is fixedly connected to the ground, the two middle free ends of the middle part of the scissor lift are connected to the second transmission mechanism through a connecting rod, and the top free end of the scissor lift is fixedly connected to the grinding mechanism. When the scissor lift is lowered, the downward movement distance of the second transmission mechanism is half of the movement distance of the grinding mechanism, so that the movement trajectory of the scissor arm is symmetrical, thereby ensuring the stability of the lifting process.

[0010] Preferably, longitudinally arranged sliding rods are fixed at both ends of the second transmission mechanism, and a sliding sleeve is slidably connected to the sliding rod, and the sliding sleeve is connected to the middle free end of the middle part of the scissors lift through a connecting rod. The longitudinal sliding design of the sliding rod and the sliding sleeve provides a stable linear motion trajectory for the scissors lift, reducing lateral deviation or shaking that may occur during the lifting process, and on the one hand, it can move vertically with the middle free end, and on the other hand, when the middle free ends approach or move away from each other, the sliding sleeve can slide on the sliding rod to avoid interference.

[0011] Preferably, the grinding mechanism includes a first mounting frame and a second mounting frame, and a lead screw slide rail arranged along the glass transmission direction is installed between the first mounting frame and the second mounting frame. The linear movement of the sliding seat is realized by the lead screw transmission, and the feed amount of the grinding head along the glass transmission direction can be accurately controlled to avoid manual operation errors. An elastic telescopic rod arranged vertically downward is installed on the sliding seat of the lead screw slide rail to provide adaptive pressure compensation in the vertical direction. When there are slight fluctuations on the glass surface, the elastic telescopic rod can automatically adjust the height to ensure that the grinding head is always in contact with the glass. An arc-shaped mounting plate is installed on the elastic telescopic rod, and multiple grinding heads are installed on the arc-shaped mounting plate. The multiple grinding heads are distributed on the arc surface to cover the curvature of different areas of the glass and realize multi-angle synchronous grinding.

[0012] Preferably, the first mounting frame and the second mounting frame are respectively connected to the top free ends of the scissor lift at both ends of the second transmission mechanism, so that the first mounting frame and the second mounting frame can move up and down together with the top free ends.

[0013] Preferably, the grinding heads are mounted on both sides of the arc-shaped mounting plate, and the grinding heads can form continuous grinding lines in the longitudinal direction.

[0014] Preferably, the first transmission mechanism includes a frame and a roller shaft, and a limit rod capable of adjusting the height and longitudinal extension length is installed on the frame of the first transmission mechanism, and the limit rod is arranged along the glass transmission direction, and a plurality of vertically arranged limit rollers are installed on the limit rod, and the limit roller extends into the roller shaft gap of the first transmission mechanism, and the limit roller is vertically embedded between the transmission roller shafts to form a physical barrier, which can correct the lateral deviation in glass transmission in real time, and a plurality of limit rollers are continuously arranged along the transmission direction to form a linear guide channel, which is particularly suitable for the stable transportation of large-size or thin glass to avoid edge collision, and the limit rod is height-adjustable to adapt to glass of different thicknesses, and the limit rod can adjust the extension length to flexibly match the width requirements of the transmission mechanism, and the limit roller adopts rolling friction rather than sliding friction to reduce the risk of scratches on the glass surface.

[0015] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0016] In the present invention, the curved surface design can fit the shape of the glass, disperse local pressure, and reduce the risk of breakage. The supporting curved plate in the flexible glass flipping device adopts a spring steel plate wrapped with a rubber sleeve, which not only provides elastic support but also avoids scratching the glass. The longitudinal beam is fixedly connected to the ground through a column, thereby enhancing the rigidity of the supporting mechanism.

[0017] Make the movement trajectory of the scissor arm symmetrical to ensure the stability of the lifting process.

[0018] The middle free end and the top free end of the scissor lift are lowered proportionally and synchronously (the top free end is lowered half of the middle one), which can achieve phased contact and limit. When the top free end descends, the grinding head contacts the glass surface first, which plays a preliminary fixing role and prevents the glass from sliding during the subsequent lowering.

[0028] Example, see Figure 1-Figure 3 , a glass intelligent processing production line, comprising a first transmission mechanism 3 for transmitting glass 4 to a grinding station, a limiting mechanism for adjusting the position of the glass 4 is installed on the first transmission mechanism 3, and the lateral position of the glass 4 when entering the grinding station is adjusted by the limiting mechanism;

[0029] The first transmission mechanism 3 includes a frame and a roller. The frame is arranged along the extension direction of the production line, including a rectangular frame on the top and a support leg at the bottom. The bottom of the support leg is fixedly connected to the ground. The roller is rotatably installed on the rectangular frame through a bearing. The axis of the roller is perpendicular to the extension direction of the production line, so that the rotation direction of the roller is the same as the extension direction of the production line.

[0030] A limit rod 1 capable of adjusting the height and longitudinal extension length is installed on the frame of the first transmission mechanism 3. Specifically, hoops are provided on both sides of the rectangular frame, and a vertical adjustment rod is vertically slidably connected in the hoop, and the vertical adjustment rod is fixedly connected to the vertical hoop by bolts. The height of the limit rod 1 can be adjusted by adjusting the height of the vertical adjustment rod, and a transverse adjustment rod is transversely slidably connected to the top of the vertical adjustment rod through a transverse hoop, and the transverse adjustment rod is fixedly connected to the transverse hoop by bolts, so that the extension length of the transverse adjustment rod can be adjusted, thereby adjusting the extension length of the limit rod 1. The transverse adjustment rod is arranged parallel to the roller shaft, and the vertical adjustment rod, the transverse adjustment rod, the vertical hoop, and the transverse hoop constitute the limit rod 1;

[0031] The limiting rod 1 is arranged along the transmission direction of the glass 4, and a plurality of vertically arranged limiting rollers 2 are installed on the limiting rod 1. The limiting rollers 2 extend into the gap between the roller shafts of the first transmission mechanism 3. Specifically, the end of the lateral adjustment rod is rotatably installed with a vertically arranged limiting roller 2 through a bearing. The limiting roller 2 is located within the range of the roller shaft. Since the glass 4 is a curved shape, the limiting roller 2 is inserted into the gap between two adjacent roller shafts, so that the glass 4 can be fully limited.

[0032] The grinding station is provided with a support mechanism 10 fixed to the ground, a second transmission mechanism 15 capable of adjusting the height, and a grinding mechanism. The support mechanism 10, the second transmission mechanism 15, and the grinding mechanism are arranged to avoid each other.

[0033] The second transmission mechanism 15 is equipped with a sensor, and the position of the glass 4 is detected by the sensor. Any sensor such as a photoelectric sensor, a laser displacement sensor, a spectral confocal sensor, etc. can be used for position detection.

[0034] The sensor detects that the glass 4 reaches the predetermined position and drives the second transmission mechanism 15 to stop rotating. At the same time, the lifting mechanism is driven to lower the second transmission mechanism 15 and the grinding mechanism. The lifting mechanism is a scissor lift 14 driven by a motor. The scissor lift 14 includes a base at the bottom, and a first connecting rod is symmetrically arranged on the base. The lower end of the first connecting rod is pin-connected to the base, and the upper end of the first connecting rod is respectively connected to the first support and the second support. The first support and the second support are laterally connected with a driving screw through a thread, and the driving screw is connected to the output shaft of the driving motor. The first support and the second support are respectively connected to the second connecting rod through a pin connection. The upper end of the second connecting rod is It is pin-connected with the third support. Here, the first support and the second support are the middle free end 16, and the third support is the top free end 13. When the driving motor is energized and drives the driving screw to rotate, it can drive the first support and the second support to move closer to or away from each other. When the first support and the second support move closer to each other, the middle free end 16 and the top free end 13 rise at the same time, and the rising distance of the middle free end 16 is half of the top free end 13; when the first support and the second support move away from each other, the middle free end 16 and the top free end 13 drop at the same time, and the rising distance of the middle free end 16 is half of the top free end 13.

[0035] The bottom of the scissor lift 14 is fixedly connected to the ground, and the two middle free ends 16 of the scissor lift 14 are connected to the second transmission mechanism 15 through a connecting rod. The second transmission mechanism 15 includes a first mounting plate and a second mounting plate arranged along the length direction of the production line. A roller is also installed between the first mounting plate and the second mounting plate through a bearing. Four columns are installed at the lower ends of the first mounting plate and the second mounting plate.

[0036] The top free end 13 of the scissor lift 14 is fixedly connected to the grinding mechanism. When the scissor lift 14 is lowered, the distance the second transmission mechanism 15 moves downward is half of the distance the grinding mechanism moves.

[0037] The second transmission mechanism 15 is also fixed with longitudinally arranged sliding rods 11 at both ends. One end of the sliding rod 11 is fixedly connected to the column, and the other end is provided with a limited end to prevent the sliding sleeve 12 from falling out. The sliding sleeve 12 is slidably connected to the sliding rod 11. The sliding sleeve 12 is connected to the middle free end 16 in the middle of the scissor lift 14 through a connecting rod, so that the height can be adjusted along with the middle free end 16, and when the middle free ends 16 are close to each other, the sliding sleeve 12 can slide longitudinally along the sliding rod 11 to avoid interference.

[0038] The support mechanism 10 includes an n-shaped frame, and an arc-shaped support pad is arranged on the top of the n-shaped frame. The support pad is detachably connected to the n-shaped frame so that different types of curved glass 4 can be easily adapted.

[0039] The supporting mechanism 10 is provided with an arc surface adapted to the lower surface of the glass 4. The glass 4 is pressed onto the supporting mechanism 10 after the second transmission mechanism 15 descends. The polishing mechanism polishes the upper surface of the glass 4 after it descends to a predetermined position. The polishing mechanism includes a first mounting frame 5 and a second mounting frame 7. The first mounting frame 5 and the second mounting frame 7 are respectively connected to the top free ends 13 of the scissor lifts 14 at both ends of the second transmission mechanism 15. A lead screw guide 6 arranged along the transmission direction of the glass 4 is installed between the first mounting frame 5 and the second mounting frame 7. An elastic telescopic rod 8 arranged vertically downward is installed on the sliding seat of the lead screw guide 6. An arc-shaped mounting plate 9 is installed on the elastic telescopic rod 8. A plurality of polishing heads are installed on the arc-shaped mounting plate 9. The polishing heads are installed on both sides of the arc-shaped mounting plate 9, and the polishing heads can form continuous polishing lines in the longitudinal direction.

[0040] The second transmission mechanism 15 includes a frame and rollers between the frames driven to rotate by a motor. A support mechanism 10 is installed in the gap between the rollers of the second transmission mechanism 15. The support mechanism 10 includes a longitudinal beam located in the gap. The upper surface of the longitudinal beam is provided with an arc that is adapted to the concave arc surface on the lower side of the glass 4. The longitudinal beam is fixedly connected to the ground through a column.

[0041] The working principle of this application is:

[0042] The glass 4 is transmitted to the subsequent grinding station through the first transmission mechanism 3. In this process, the limiting roller 2 is used for preliminary limiting, so as to adjust the position of the glass 4 along the transmission direction. After the glass 4 is transported to the second transmission mechanism 15, it is detected by the sensor, and the second transmission mechanism 15 stops transmission and drives the scissor lift 14 to lower at the same time. When the scissor lift 14 is lowered, the middle free end 16 and the top free end 13 will be lowered at the same time, and the top free end is half of the middle free end 16. Therefore, the grinding head will contact with the upper surface of the glass 4 first, and limit the glass 4 after contact. The glass 4 is then pressed on the supporting mechanism 10, and the position of the glass 4 along the transmission direction is adjusted by the limiting roller 2 on the first transmission mechanism 3 to ensure that the glass 4 is When entering the grinding station, it is strictly aligned with the processing path of the subsequent equipment to reduce the processing error caused by offset. When the glass 4 reaches the second transmission mechanism 15, the sensor triggers a stop signal to avoid excessive displacement of the glass 4 due to inertia or transmission error. The middle free end 16 and the top free end 13 of the scissors lift 14 are synchronously lowered in proportion (the top drop is half of the middle), which can achieve staged contact and limit. When the top free end 13 drops, the grinding head first contacts the surface of the glass 4 to play a preliminary fixing role to prevent the glass 4 from sliding during the subsequent drop. The processing stability is ensured by step-by-step fixing. When the glass 4 is finally pressed on the supporting mechanism 10, the middle drop of the scissors lift 14 further releases the pressure to evenly distribute the weight of the glass 4 on the supporting structure.

[0043] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
