Description

Technical Field

[0001] This application relates to the field of photovoltaic glass cutting technology, and in particular to a device for precise cross-cutting and scribing of photovoltaic glass. Background Technology

[0002] Photovoltaic glass is an important encapsulation material for solar modules. It features high strength, high light transmittance, and high weather resistance. Tempered photovoltaic glass, when applied to photovoltaic modules, allows them to withstand greater wind pressure, sandstorms, hail, and significant diurnal temperature variations and harsh environments, protecting the solar cells. Furthermore, after coating, photovoltaic glass exhibits high light transmittance, meeting the need for solar cells to generate more electricity. It is commonly used in the production and processing of photovoltaic glass panels.

[0003] Existing technologies, such as the utility model with publication number CN215327740U, specifically disclose a glass cutting device for photovoltaic glass production, including a support frame and a conveyor belt. A transverse linear guide rail is fixedly connected to the top of the support frame. The top of the transverse linear guide rail is connected to two longitudinal linear guide rails via a sliding seat. The top of the longitudinal linear guide rails is fixedly connected to a connecting pad by bolts. A left cutting wheel and a right cutting wheel are arranged on the lower side of the connecting pad, respectively located on both sides of the longitudinal linear guide rails. A micro-suction cup is arranged on the right side of the longitudinal linear guide rails, located above the conveyor belt, and connected to the top of a sliding frame. The sliding frame is slidably connected to the support frame. This utility model achieves the purpose of segmented cutting and slitting of glass, and also facilitates the adjustment of the glass cutting dimensions. It eliminates the need for glass handling and separate cutting, reducing operational steps and improving work efficiency.

[0004] In the processing and production of photovoltaic glass panels, in the existing photovoltaic glass production process, when the glass panel is cut horizontally, if the cutting wheel presses down before entering the glass edge to cut, the cutting wheel will collide with the glass edge, which can easily damage the cutting wheel and cause breakage. If the cutting wheel enters too far into the glass edge before pressing down to cut, the starting position of the cutting line will be too far from the glass edge, which can easily cause defects such as uneven edge breaking or edge chipping when the glass is broken. Utility Model Content

[0005] One of the technical problems to be solved by this application is that in the existing photovoltaic glass production process, when the glass plate is cut horizontally, when the cutting wheel presses down first and then enters the glass edge to cut, the cutting wheel will collide with the glass edge, which can easily damage the cutting wheel and cause breakage. When the cutting wheel enters the glass edge too much before pressing down to cut, the starting position of the cutting line will be too far from the glass edge, which can easily cause defects such as uneven edge breaking or edge chipping when breaking.

[0006] To solve the above technical problems, this application provides a photovoltaic glass precision cross-cutting and scribing device, including: a longitudinal linear motor module, and a gantry frame is installed on the upper surface of the longitudinal linear motor module;

[0007] Cross-cutting assembly, the cross-cutting assembly is mounted on one end surface of the gantry; and

[0008] The glass plate is located directly below the transverse component;

[0009] The transverse cutting component includes a transverse sliding seat, one side surface of which is fixedly connected to the surface of the gantry frame. A vertical servo module is mounted on the upper surface of the transverse sliding seat, and a lead screw guide module is mounted on the bottom surface of the vertical servo module. A cylinder seat is slidably connected to the surface of the lead screw guide module, and a precision cylinder is fixedly connected to the inner wall of the cylinder seat. A cutter head mechanism is mounted on the output end of the precision cylinder.

[0010] In some embodiments, the slitting assembly further includes a proportional valve located on the upper surface of the gantry and electrically connected to a precision cylinder.

[0011] In some embodiments, two laser detectors are mounted on the surface of the transverse slide seat. The two laser detectors are located on both sides of the precision cylinder and are perpendicular to the surface of the glass plate.

[0012] In some embodiments, the cutting head mechanism includes a docking post, the upper end of which is fixedly connected to the output end of a precision cylinder, a fixing post abutting the bottom surface of the docking post, and the fixing post and the docking post having the same mounting ring threadedly connected to each other on their adjacent sides, and a cutting wheel fixedly connected to the bottom surface of the fixing post.

[0013] In some embodiments, a plug is fixedly connected to the lower surface of the docking post, and a slot is provided on the upper surface of the fixing post, with the surface of the plug engaging with the inner wall of the slot.

[0014] In some embodiments, a friction ring is fixedly connected to the surface of the mounting ring, and the surface of the friction ring is provided with a plurality of friction grooves.

[0015] In some embodiments, the cutter wheel is a universal wheel, and the precision cylinder is a low-friction cylinder.

[0016] Through the above technical solution, the photovoltaic glass precision cross-cutting and scribing device provided in this application, during normal production, the glass is conveyed along the flow direction, and the gantry moves synchronously with the glass under the drive of the linear motor module. At the same time, the cross-cutting component moves. When the laser detector detects the edge position of the glass, the cutter head mechanism will cut and scribing after entering the glass edge. When the laser detector detects no glass, the cutter head mechanism will lift the blade and stop cutting and scribing before reaching the glass edge. After the glass cutting and scribing is completed, the linear motor module drives the gantry to move in the opposite direction and return to the cutting start position for the next cycle. The edge position of the photovoltaic glass strip and glass plate is detected when it enters the cross-cutting before the blade is precisely cut and scribing. When exiting the glass edge, the edge position is detected in advance and the blade is lifted in advance, so that the scribing entry and exit positions are more accurate, avoiding the collision between the blade wheel and the glass, which will cause blade wheel damage or glass fragments. At the same time, the cutting line is kept as close as possible to the edge of the glass to prevent defects such as uneven edge breaking or edge chipping when breaking. Attached Figure Description

[0031] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a photovoltaic glass precision cross-cutting and scribing device, including a longitudinal linear motor module 1, and a gantry 2 installed on the upper surface of the longitudinal linear motor module 1;

[0032] Cross-cutting component 3, which is mounted on one end surface of the gantry frame 2; and

[0033] Glass plate 4 is located directly below the transverse cutting component 3.

[0034] The specific settings and functions of the cross-cutting component 3 and the cutter head mechanism 31 will be discussed in detail below.

[0035] Reference Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment: the transverse cutting component 3 includes a transverse shift seat 34, one side surface of which is fixedly connected to the surface of the gantry 2. A vertical servo module 36 is installed on the upper surface of the transverse shift seat 34, and a lead screw guide module 35 is installed on the lower surface of the vertical servo module 36. A cylinder seat 32 is slidably connected to the surface of the lead screw guide module 35. A precision cylinder 33 is fixedly connected to the inner wall of the cylinder seat 32. A cutter head mechanism 31 is installed at the output end of the precision cylinder 33. The transverse cutting component 3 also includes a proportional valve 37, which is located on the upper surface of the gantry 2 and electrically connected to the precision cylinder 33. Two laser detectors 38 are installed on the surface of the transverse shift seat 34. The two laser detectors 38 are located on both sides of the precision cylinder 33 and are perpendicular to the surface of the glass plate 4.

[0036] The longitudinal linear motor module 1 is installed on the glass plate 4 conveyor belt, and the cross-cutting component 3 is installed on the linear motor mover on the gantry 2, which can move laterally back and forth. The gantry 2 is installed on the mover of the longitudinal linear motor module 1, which can drive the gantry 2 and the cross-cutting component 3 to move longitudinally back and forth. The cutter head of the cross-cutting component 3 is installed on the precision cylinder 33, and the pressure of the cutter wheel 311 during cutting can be precisely adjusted by the proportional valve 37. The precision cylinder 33 is fixed by the cylinder seat 32 and is installed as a whole on the slider of the lead screw guide module 35. The slide block can move up and down; the lead screw guide module 35 is installed on the horizontal slide block 34 and is controlled by the vertical servo module 36 to move up and down; the proportional valve 37 is installed on the upper part of the horizontal slide block 34 to control the pressure of the precision cylinder 33; the laser detector 38 is installed in the middle of the horizontal slide block 34, with one on each side of the cutter head. The laser detector 38 can be used to directly observe the laser line emitted by the laser detector 38 irradiating the glass plate 4, and at the same time, it is convenient to effectively sense the contact with the glass plate 4, so as to use it for precision cutting detection of the edge position of the glass plate 4.

[0037] The cutting head mechanism 31 includes a docking post 313, the upper end of which is fixedly connected to the output end of the precision cylinder 33. The bottom surface of the docking post 313 abuts against a fixing post 312. The fixing post 312 and the docking post 313 are threaded together on the side close to each other, and the same mounting ring 316 is threadedly connected to them. The bottom surface of the fixing post 312 is fixedly connected to a cutting wheel 311. The lower surface of the docking post 313 is fixedly connected to an insert block 314. The upper surface of the fixing post 312 has a slot 315. The surface of the insert block 314 is inserted into the inner wall of the slot 315. The surface of the mounting ring 316 is fixedly connected to a friction ring 317. The surface of the friction ring 317 has several friction grooves.

[0038] When the cutter wheel 311 is used for a long time, in order to facilitate the replacement and limiting of the cutter wheel 311 in the entire cutter head mechanism 31, the docking post 313 fixed at the output end of the precision cylinder 33 is docked with the fixing post 312 fixedly connected to the cutter wheel 311, and then the mounting ring 316 is used for threaded docking and fixing. During this process, the slot 315 opened on the surface of the fixing post 312 can be used to dock with the insert block 314 fixed on the lower surface of the docking post 313 to prevent the position of the entire cutter wheel 311 from shifting. At the same time, the friction ring 317 is used to increase friction and facilitate the rotation operation of the mounting ring 316.

[0039] The cutter wheel 311 is a universal wheel. The cutter wheel 311 in the cutter head mechanism 31 is universal, which makes it easy for the cross-cutting component 3 to achieve bidirectional cutting. The precision cylinder 33 is a low-friction cylinder. The precision cylinder 33 is a low-friction cylinder, which ensures precise control of the cutter pressure. When the glass plate 4 is detected to be broken or missing material during cutting, the cutter wheel 311 will be lifted and skipped to prevent the cutter wheel 311 and the glass plate 4 from being broken and impacted.

[0040] During normal production, glass plate 4 is conveyed along the flow direction on the conveyor belt. Gantry 2 moves synchronously with glass plate 4 under the drive of the linear motor module. The cross-cutting assembly 3 and glass plate 4 are relatively synchronized in the flow direction. During cutting, the cross-cutting assembly 3 moves laterally. The proportional valve 37 controls the precision cylinder 33 to press down the cutter head while ensuring stable cutter pressure. When the laser detector 38 detects the edge of glass plate 4, the vertical servo module 36 activates after the cutter head enters the edge of glass plate 4, driving the upper slider of the lead screw guide module 35 and the cylinder seat 32 to move downwards. The precision cylinder 33 and the cutter head move downwards synchronously. By adjusting appropriate parameters, the cutter head will... After entering the glass plate 4, the blade is positioned at an appropriate location to cut and scribble the glass plate 4, preventing the blade wheel 311 from colliding with the edge of the glass plate 4, which could damage the blade wheel 311 or break the glass plate 4. When the laser detector 38 detects the edge of the glass plate 4, the blade head will stop cutting and scribing before reaching the edge of the glass plate 4, controlled by the vertical servo module 36, to prevent the blade wheel 311 from impacting the edge. When another laser detector 38 detects the edge of the glass plate 4, the horizontal movement stops. At this time, the cutting and scribing of the glass plate 4 is completed, and the linear motor module drives the gantry 2 to move in the opposite direction to return to the cutting start position for the next cycle.
