Description

Technical Field

[0001] This invention relates to the technical field of photovoltaic glass production, and specifically to a cutting device and method for photovoltaic glass production. Background Technology

[0002] The current glass cutting process in photovoltaic glass production typically involves first using a cutting wheel to create a cut line on the glass surface, and then using a push rod mounted on the cutting table to lift the glass below the cut line, causing the glass to break at the cut line. This process has the following drawbacks:

[0003] 1. When the glass breaks and falls synchronously with the top rod, there is a problem of glass collision due to insufficient movement distance on both sides after the two separated glass pieces. In severe cases, it may even cause damage to the glass edge. In detail, the main reason for the above glass collision is that the existing cutting surface has a large resistance to the movement of the glass, and there is no control over the movement direction of the glass during the falling process after it is broken.

[0004] 2. Taking the dust removal and breaking machine as an example, this structure removes dust on one side by placing a dust suction hood at the top of the breaking position. Due to the limited dust removal effect, it is difficult to completely remove the debris that falls during the breaking process. Other structures include a blowing device or a negative pressure dust suction device placed on the workbench. Since these are all single-sided dust suction structures, it is difficult to completely remove the debris generated during the breaking of photovoltaic glass.

[0005] To address these issues, we provide a cutting apparatus and method for photovoltaic glass production. Summary of the Invention

[0006] To address the problems existing in the prior art, one objective of this invention is to provide a cutting device for photovoltaic glass production. This device achieves the separation of glass through an air blowing section, and, in conjunction with a first and third air supply unit, assists in achieving the floating separation of the glass. This reduces the resistance of the cutting surface to the movement of the glass, widens the gap between the two pieces of glass after cutting, and reduces the glass collision problem caused by insufficient movement distance on both sides after cutting. Another objective of this invention is to provide a cutting method for photovoltaic glass production, so as to maximize the effectiveness of the cutting device for photovoltaic glass production.

[0007] To achieve the above objectives, the present invention provides a cutting device for photovoltaic glass production, comprising:

[0008] A workbench, the surface of which is used for cutting and separating photovoltaic glass;

[0009] The lifting section is positioned at the photovoltaic glass cutting point and lifts the photovoltaic glass cutting point to separate the photovoltaic glass.

[0010] The blowing section is positioned below the photovoltaic glass and provides a pushing airflow to move the separated photovoltaic glass outward and create a gap between the two separated photovoltaic glass pieces as they fall.

[0011] The above structure uses an air blowing section to help widen the gap between the two glass panes after separation, thereby reducing the glass collision problem caused by insufficient movement distance on both sides after cutting.

[0012] The aforementioned air supply unit includes a first air supply unit and a second air supply unit placed on the workbench. The first air supply unit provides a vertically upward airflow to make the separated photovoltaic glass float, and the second air supply unit provides a pushing airflow to push the separated photovoltaic glass to move outward.

[0013] The above structure achieves the separation action of the glass through the air blowing part, and with the assistance of the first and third air supply units, it achieves the floating separation action of the glass, reduces the resistance of the existing cutting surface to the movement of the glass, widens the gap between the two pieces of glass after cutting, and further reduces the glass collision problem caused by insufficient movement distance on both sides after cutting.

[0014] As a further optimization of the above solution, the second air supply unit includes an inclined hole placed in the lifting section and an air supply section that provides airflow to the inclined hole. The inclined hole corresponds to the position of the photovoltaic glass. By designing the second air supply unit in the lifting section, the space below the glass and the lifting section are fully utilized, so that the lifting section has the dual functions of lifting and blowing air. Furthermore, the second air supply unit gradually shortens the blowing distance between itself and the glass as the lifting section rises. That is, the closer to the top of the lifting section, the greater the air force of the second air supply unit. In other words, during the process of the glass separating and descending, a deceleration and external pushing action is implemented to avoid the gap between the two glass panes being too large.

[0015] As a further optimization of the above solution, the lifting section is also equipped with a collection unit. The collection unit has an opening for debris to enter, and the first suction unit provides suction to the collection unit to allow debris to enter. The design of the collection unit enables the lifting structure in this invention to achieve a dual-chamber structure. One chamber is used to provide airflow, i.e., the second air supply unit, for pushing the glass outward, and the second chamber is designed to absorb debris. This design further utilizes the lifting structure, enabling it to absorb debris. Since the generation of glass debris mostly occurs during the glass separation process, and the glass separation is achieved by the lifting section, the distance between the lifting section and the location where the glass debris is generated is relatively close when the glass separation occurs. At this time, the distance between the collection unit and the location where the debris is generated is also relatively close, which can maximize the collection effect of the debris.

[0016] As a further optimization of the above solution, the workbench includes two fixed platforms arranged opposite each other. The first air supply unit is arranged on the fixed platform. A movable platform is provided on the side of the fixed platform near the photovoltaic glass cutting point. The movable platform is pivotally connected to the fixed platform. The bottom surface of the movable platform is where the third air supply unit allows the movable platform to rotate around the pivot connection point of the movable platform after the photovoltaic glass is lifted by the lifting part. The bottom surface of the photovoltaic glass is located on the rotation path of the movable platform to support the separated photovoltaic glass. In this invention, the workbench is designed as a double-platform structure. The fixed platform is designed to be located only at the end away from the glass separation point, that is, the floating action is only achieved at the end away from the glass separation point, reducing the air supply area of ​​the third air supply unit and saving energy.

[0017] As a further optimization of the above solution, with the end of the movable platform away from the hinge as the protruding end, during the lifting process of the photovoltaic glass, the protruding end of the movable platform slides and seals against the bottom surface of the photovoltaic glass, and forms an isolation space on the side of the movable platform facing the lifting part to isolate the debris generated after the photovoltaic glass is separated within the isolation space. In the design of the movable platform in the above double platform, during the lifting action of the lifting part, the protruding end of the movable platform slides and seals against the bottom surface of the photovoltaic glass, and forms an isolation space on the side of the movable platform facing the lifting part to isolate the debris generated after the photovoltaic glass is separated within the isolation space, so as to prevent the debris generated during the glass separation process from entering the fixed platform part and the third air supply unit. Furthermore, the design of the isolation space reduces the space area for collecting debris in the collection part, further improving the debris collection effect of the collection part, achieving two goals at once.

[0018] As a further optimization of the above solution, the lifting section is also equipped with a sealing unit. The sealing unit is connected to both sides of the lower end of the lifting section. The side of the sealing unit away from the lifting section contacts the side wall of the third air supply unit. The design of the sealing section further improves the sealing effect of the isolation space, that is, it improves the debris collection effect of the collection section.

[0019] As a further optimization of the above solution, the contact part between the sealing unit and the third air supply unit is a brush structure, and the sealing unit moves up and down along the side wall of the third air supply unit as the lifting structure moves up and down. The design of the brush structure has the function of cleaning the side wall of the third air supply unit during the lifting process, so that the sealing unit can clean the side wall of the third air supply unit while improving the sealing effect, thereby further enhancing the actual use function of the sealing unit.

[0020] As a further optimization of the above solution, for the absorption of debris on the upper surface of the photovoltaic glass cut, the present invention places the second suction unit at the top of the photovoltaic glass cut. The suction part provides suction to the second suction unit to absorb debris that has not entered the isolation space from the top of the photovoltaic glass cut. The design of the above structure makes the debris absorption action at the glass cut a two-way absorption function, ensuring complete removal of debris generated at the glass cut and improving the debris absorption effect.

[0021] The cutting method for photovoltaic glass production includes the following steps:

[0022] S1, Obtain the photovoltaic glass to be separated and place it on the worktable;

[0023] S2, control the top rod to rise, the third air supply unit blows air, the movable table flips and works with the closed unit to form an isolation space, the first air intake unit sucks air and sucks the debris that enters the isolation space when the photovoltaic glass is broken into the collection unit, while the second air intake unit sucks air and removes the debris that does not enter the isolation space.

[0024] S3, control the top rod to descend, the first air supply unit blows air and the second air supply unit blows air to separate the photovoltaic glass and create a gap;

[0025] S4, when the photovoltaic glass approaches the workbench, shut down the first air supply unit and the second air supply unit.

[0026] The above-mentioned method of using the cutting device for photovoltaic glass production is designed to fully realize the use of the cutting device for photovoltaic glass production and maximize its effectiveness.

[0027] The cutting apparatus and method for photovoltaic glass production of the present invention have the following beneficial effects:

[0028] 1. A cutting device for photovoltaic glass production according to the present invention achieves the separation action of glass through an air blowing part, and is used in conjunction with a first and third air supply unit to assist in the floating separation action of the glass, thereby reducing the resistance of the existing cutting table to the movement of glass, widening the gap between the two pieces of glass after cutting, and further reducing the glass collision problem caused by insufficient movement distance on both sides of the glass after cutting.

[0029] 2. A cutting device for photovoltaic glass production according to the present invention, by designing the second air supply unit in the lifting part, makes full use of the space below the glass and the lifting part, so that the lifting part has dual functions of lifting and blowing air. Moreover, the second air supply unit gradually shortens the blowing distance between itself and the glass as the lifting part rises, that is, the air force of the second air supply unit is the greatest closer to the top of the lifting part. In other words, during the glass separation and descent process, a deceleration external push is implemented to avoid the gap between the two glass pieces being too large. Simultaneously, the present invention further improves the lifting structure so that the lifting structure has the function of absorbing debris. Since the generation of glass debris mostly occurs during the glass separation process, and the glass separation is achieved by the lifting part, that is, when the glass separation action occurs, the distance between the lifting part and the glass debris generation point is relatively close. At this time, the distance between the collection unit and the debris generation point is also relatively close, which can maximize the debris collection effect.

[0030] 3. A cutting device for photovoltaic glass production according to the present invention, regarding the workbench, the present invention designs the workbench as a double-table structure, wherein the fixed table is designed only at one end of the glass separation point, that is, the floating action is only achieved at the end of the glass separation point, reducing the air supply area of ​​the third air supply unit and saving energy; the design of the movable table in the double table, during the lifting action of the lifting part, the extended end of the movable table slides and seals with the bottom surface of the photovoltaic glass, and the movable table facing the lifting part forms an isolation space to isolate the debris generated after the photovoltaic glass is separated in the isolation space, so as to prevent the debris generated during the glass separation process from entering the fixed table part and the third air supply unit. Furthermore, the design of the isolation space reduces the space area for the collection part to collect debris, further improving the debris collection effect of the collection part, achieving two goals at once.

[0031] 4. A cutting device for photovoltaic glass production according to the present invention further improves the sealing effect of the isolation space by designing a closed unit, that is, improves the debris collection effect of the collection part, and designs the closed unit as a brush structure, which has the function of cleaning the side wall of the third air supply unit during the lifting action of the lifting part. Thus, the closed unit not only improves the sealing effect, but also cleans the side wall of the third air supply unit, thereby further enhancing the actual use function of the closed unit.

[0032] 5. A cutting device for photovoltaic glass production according to the present invention, for the absorption of debris on the upper surface of the photovoltaic glass cutting area, the present invention places a second suction unit at the top of the photovoltaic glass cutting area, and the suction part provides suction to the second suction unit to absorb debris that has not entered the isolation space from the top of the photovoltaic glass cutting area. The design of the above structure makes the debris absorption action at the glass cutting area a two-way absorption function from top to bottom, so as to ensure complete removal of debris generated at the glass cutting area and improve the debris absorption effect.

[0033] 6. The present invention provides a cutting method for photovoltaic glass production, which fully realizes the use of the cutting device for photovoltaic glass production and maximizes the effect of the cutting device for photovoltaic glass production.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] like Figure 1 As shown, in the first embodiment, the photovoltaic glass production cutting device of the present invention includes a worktable 1, the surface of which is used for cutting and separating photovoltaic glass. The lifting part in this embodiment is presented as a lifting rod 4 structure. See detailed reference... Figure 1 In this embodiment, the aforementioned push rod structure is a roughly round rod structure, and the push rod 4 divides the worktable 1 into left and right table surfaces.

[0048] For further details, please refer to [link / reference]. Figure 1 In this embodiment, the workbench 1 is also provided with a set of air outlets 10. When the glass 9 needs to be moved, the airflow flows upward from the air outlets 10 to support the glass 9 and facilitate its movement. During the cutting operation, the glass 9 to be cut is first placed on the workbench 1. At this time, the top rod 4 is located at a low position and below the workbench 1, as shown by the dotted line in the figure. The cutting wheel is used to draw a cutting line on the glass surface. Then, the top rod 4 lifts the glass 9 from below the cutting line. At this time, the top rod 4 reaches a high position and is higher than the workbench 1, as shown by the solid line in the figure, so that the glass is broken at the cutting line.

[0049] It should be noted that the workbench 1 in Embodiment 1 is fixed, and the top rod 4 is a solid rod-shaped structure. The top rod 4 is usually lifted by a crank lifting mechanism or cylinder, which are all mature technologies in this industry.

[0050] like Figures 2 to 8 As shown in Embodiment 2, the photovoltaic glass production cutting device of the present invention includes a worktable 1 for supporting glass 9 and a top rod 4 for breaking glass 9. The worktable 1 is provided with a set of air outlets 10, and the top rod 4 divides the worktable 1 into left and right table surfaces.

[0051] The aforementioned left and right platforms each include a movable platform 2 and a fixed platform 3. The movable platform 2 is closer to the top rod 4 than the fixed platform 3. The air outlet 10 is located on the fixed platform 3.

[0052] For detailed reference Figure 2 and Figure 3 The movable platform 2 is elongated, with its long side parallel to the axis of the top rod. A pivot 20 is provided at the end of each movable platform 2 away from the top rod 4, and the pivot 20 is fixed to one end of the adjacent fixed platform.

[0053] like Figure 3 As shown, a first bellows 21 of the same length as the movable platform 2 is provided below the movable platform 2. The top surface of the first bellows 21 has a slit 22 with an opening of the same length as the first bellows pointing upwards towards the top rod. When the top rod lifts the glass, the airflow ejected from the slit 22 causes the movable platform 2 to rotate upwards from a horizontal state around the pivot 20 until the far end of the movable platform 2 is pressed against the lower surface of the glass 9, forming a sliding seal contact to prevent glass fragments generated during breakage from entering the fixed platform and the movable platform.

[0054] like Figure 2 , Figure 3 as well as Figure 4As shown, the lower port of the first air box 21 is connected to the first air supply pipe 23, the first quick-opening valve 24 and the first blower 25.

[0055] like Figure 2 , Figure 3 and Figure 6 As shown, a second air box 32 is provided below each fixed platform 3, and the lower port of the second air box 32 is connected to the second air supply pipe 33, the second quick-opening valve 34 and the second blower 35.

[0056] It should be noted that in this embodiment, the first air box 21, slit 22, first air supply pipe 23, first quick-opening valve 24 and first blower 25 constitute the third air supply unit, so that after the movable platform 2 lifts the photovoltaic glass in the lifting part, it performs a flipping action with the pivot connection of the movable platform as the center. The bottom surface of the photovoltaic glass is located on the flipping path of the movable platform to support the separated photovoltaic glass.

[0057] It should be noted that in this embodiment, the second air box 32, the second air supply pipe 33, the second quick-opening valve 34, and the second blower 35 constitute the first air supply unit to provide vertically upward airflow so that the separated photovoltaic glass floats.

[0058] Detailed, such as Figure 3 , Figure 5 as well as Figure 8 As shown, the push rod 4 in this embodiment has a dual-cavity structure, including a first cavity 5 and a second cavity 6. The first cavity 5 is the second air supply unit in the blowing section, and the second cavity is the collection unit. Details are as follows:

[0059] The first cavity 5 is a cylindrical cavity with a circular cross-section. The upper half of the outer periphery of the cavity is provided with a set of protrusions 7 and a set of gaps 71 that are spaced apart from each other and have a semi-circular cross-section.

[0060] The stroke of the push rod 4 includes a low position and a high position. When the position is low, the line 72 connecting the vertices of the outer circumference arc of the protrusion 7 is lower than the worktable 1. When the position is high, the line 72 connecting the vertices of the outer circumference arc of the protrusion 7 is higher than the worktable 1.

[0061] The protrusion 7 has two rows of oblique holes 73 that are symmetrical and point upwards towards the worktable 1. The outlet of the oblique holes 73 is higher than the worktable 1 when the top rod 4 is in a high position.

[0062] One end of the first cavity 5 is connected to the compressed air supply mechanism 53, which includes a pulse valve 52, via a first spiral telescopic hose 51. The first spiral telescopic hose 51, the pulse valve 52, and the compressed air supply mechanism 53 constitute the air supply part.

[0063] When the push rod 4 moves from the low position to the high position, the vertex connecting line 72 contacts and lifts the glass until it reaches the high position and breaks the glass; when the push rod moves from the high position to the low position, the pulse valve 52 works, and the pulse airflow is ejected through the first cavity 5 and the oblique hole 73 to separate the two broken pieces of glass.

[0064] The second cavity 6 is a cylindrical cavity with a semi-circular cross-section. The cavity surrounds the lower half of the outer periphery of the first cavity 5. The extension line 60 of the outer periphery arc of the second cavity 6 coincides with the outer periphery arc line 70 of the protrusion 7.

[0065] Two rows of upward-facing openings 61 are provided at the interface between the second cavity 6 and a set of gaps 71.

[0066] One end of the second cavity 6 is connected to the first exhaust pipe 63, the first dust collector 64 and the first exhaust fan 65 through the second spiral telescopic hose 62. The second spiral telescopic hose 62, the first exhaust pipe 63, the first dust collector 64 and the first exhaust fan 65 constitute the first air intake unit.

[0067] When the glass breaks, the first induced draft fan 65 introduces the glass fragments generated by the breakage into the second cavity 6 through the gap 71 and the opening 61, and then they are collected and processed by the first dust collector 64.

[0068] Furthermore, such as Figure 7 As shown, the brush structure of the closed unit in this embodiment consists of a brush row 8 and a brush head 81. A pair of brush rows 8 are symmetrically arranged on both sides of the second cavity 6. The brush head 81 of the brush row 8 forms a sliding contact with the outer wall surface 26 of the first air box 21 as the top rod 4 moves up and down, which is used to prevent the glass fragments generated by breaking from escaping.

[0069] Furthermore, a dust suction hood 41 is provided above the top rod 4. The dust suction hood is parallel to the top rod 4 and of the same length. The suction part provides suction for the second suction unit to absorb debris that has not entered the above-mentioned isolation space from the top of the photovoltaic glass cut.

[0070] In this embodiment, a more detailed version of the above solution is provided:

[0071] The width W of the protrusion 7 and the gap 71 are equal, both being 3mm. The radial height H of the protrusion 7 is 5mm. The top rod 4 is lifted by a crank lifting mechanism.

[0072] The first air box 21 has a cross-section of a right trapezoid, with the right-angled side of the trapezoid on the side closer to the top rod, and the brush head 81 makes sliding contact with the outer wall surface 26 of the right-angled side; the second air box 32 has a cross-section of an isosceles trapezoid.

[0073] The far end of the movable platform 2 is an inclined surface 27, on which a fiber or elastomeric material is provided. When the movable platform 2 is flipped upward, the inclined surface 27 is pressed against the lower surface of the glass 9, forming a sliding seal contact. The fiber or elastomeric material can be selected from textile fibers, sponge, leather, rubber, polytetrafluoroethylene plastic, etc.

[0074] The angle θ between the axis of the inclined hole 73 and the horizontal plane is 20°.

[0075] The dust hood 41 is connected to the second exhaust pipe 42, the second dust collector 43, and the second exhaust fan 44. When the first exhaust fan 65 is working, the second exhaust fan 44 works synchronously. The debris that the first exhaust fan cannot completely suck up is sucked up by the second exhaust fan and collected and processed by the second dust collector 43.

[0076] The compressed air supply mechanism 53 includes a compressed air pipe 54, a pulse valve 52, a pressure reducing valve 55, an air tank 56, and an air compressor 57. The pulse valve 52 operates with one or more pulses.

[0077] When the pulse valve 52 is working, the second quick-opening valve 34 works synchronously, causing the air outlet 10 to float the glass, and the auxiliary oblique hole 73 to separate the two broken pieces of glass.

[0078] The brush pack 8 includes a slot 80 and a plug 82. The slot 80 is fixedly connected to the outer wall 66 of the second cavity 6. One side of the plug 82 is connected to the brush base 83 and the brush head 81 in sequence.

[0079] The aforementioned quick-opening valve, pulse valve, air compressor, blower, induced draft fan, dust collector, and lifting mechanism of the top rod are all existing technology equipment, and they are all connected to the control mechanism by wires to form an electrical signal connection for control.

[0080] The above-mentioned method for cutting a photovoltaic glass production apparatus includes the following steps:

[0081] S1, Obtain the photovoltaic glass to be separated and place it on the worktable;

[0082] S2, control the top rod to rise, the third air supply unit blows air, the movable table flips and works with the closed unit to form an isolation space, the first air intake unit sucks air and sucks the debris that enters the isolation space when the photovoltaic glass is broken into the collection unit, while the second air intake unit sucks air and removes the debris that does not enter the isolation space.

[0083] S3, control the top rod to descend, the first air supply unit blows air and the second air supply unit blows air to separate the photovoltaic glass and create a gap;

[0084] S4, when the photovoltaic glass approaches the workbench, shut down the first air supply unit and the second air supply unit.

[0085] A preferred method of using a cutting device for photovoltaic glass production includes the following steps:

[0086] S1: Position the push rod 4 in the low position, close the first quick-opening valve 24 and the second quick-opening valve 34, and start the first blower 25 and the second blower 35 for standby; close the pulse valve 52, start the air compressor 57, and fill the air tank 56 with air for standby;

[0087] S2: Place the photovoltaic glass 9 on the workbench 1 and use a cutting wheel to make cutting lines on the glass surface;

[0088] S3: Open the second quick-opening valve 34, and the air flows out through the second air supply pipe 33, the second air box 32, and the air outlet 10. Use the air flow to support the glass to easily move the glass. After aligning the cut line with the top rod 4, close the second quick-opening valve 34.

[0089] S4: Start the first induced draft fan 65 and the second induced draft fan 44, open the first quick-opening valve 24. At this time, the glass 9 presses against the movable table 2, and no gas flows out of the slit 22, so that the first bellows 21 is filled with air.

[0090] S5: Activate the top rod lifting mechanism to move the top rod 4 from the low position to the high position. A set of protrusions 7 on the top rod lifts the glass. As the glass leaves the movable platform 2, the airflow ejected from the slit 22 causes the movable platform 2 to rotate upward from the horizontal state around the pivot 20. By controlling the pressure of the ejected airflow, the movable platform 2 continues to rotate as the distance between the glass 9 and the movable platform 2 increases, so that the inclined surface 27 at the far end of the movable platform is always in close contact with the lower surface of the glass 9, forming a sliding seal contact, thereby isolating the upper surfaces of the fixed platform and the movable platform from the top rod space.

[0091] When the top rod 4 rises to the high position, the glass breaks at the cut line. The specific position of the high position varies depending on the area, thickness, cut line distribution, cut quality, glass material, and glass annealing quality of the photovoltaic glass. The lifting mechanism of the top rod 4 continues to rise until the glass breaks.

[0092] At the same time, the brush head 81 slides in contact with the outer wall surface 26 of the first air box 21 as the top rod 4 moves up and down;

[0093] Because the movable tabletop 2 and the brush head 81 form a relatively enclosed space, the glass shards generated by the breakage are confined within this enclosed space. The glass shards can only pass through a set of gaps 71, enter the second cavity 6 through the opening 61, and then be collected and processed by the first dust collector 64 via the first exhaust pipe 63. The shards that the first exhaust fan fails to completely suck up are supplemented by the second exhaust fan 44. The shards pass through the crack 90 formed by the glass breakage, the dust hood 41, and the second exhaust pipe 42, and are collected and processed by the second dust collector 43. They cannot spread to the upper surfaces of the fixed tabletop 3 and the movable tabletop 2, causing scratches on the lower surface of the glass, or escape from the gap between the top rod 4 and the first air box 21 and fall to the ground.

[0094] S6: Close the first quick-opening valve 24, the movable platform 2 returns to the initial horizontal state, and then move the top rod 4 from the high position to the low position. During the descent, activate the pulse valve 52 and the second quick-opening valve 34, so that the pulse valve works for one or more pulses. Preferably, in this embodiment, the outlet pressure of the pressure reducing valve 55 is 0.35~0.5Mpa, the pulse valve 52 works for one pulse, and the working time is 20~100ms. The airflow ejected from the inclined hole 73 is decomposed into an upward thrust and a horizontal thrust to the side. The airflow ejected from the air outlet 10 supports the glass 9. The two work together to make the two broken pieces of glass move away from each other.

[0095] S7: When the glass is close to the tabletop, close the pulse valve and the second quick-opening valve, and the two pieces of glass are separated by an appropriate distance and placed stably on the tabletop, thereby avoiding collisions.

[0096] In summary, the photovoltaic glass production cutting device of the present invention achieves the separation action of the glass through the air blowing part, and the first and third air supply units assist in the floating separation action of the glass, reducing the resistance of the existing cutting surface to the movement of the glass, widening the gap between the two pieces of glass after cutting, and further reducing the glass collision problem caused by insufficient movement distance on both sides of the glass after cutting.

[0097] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
