Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a coating device and a cutting device. Background Technology

[0002] In the glass production process, in order to provide good cutting conditions for the glass cutting process, cutting fluid is usually applied to the glass cutting surface to improve the cutting quality.

[0003] In the actual cutting process, due to the need for later glass storage and to save cutting fluid, the cutting fluid is usually applied roughly to the area to be cut. However, when the glass is conveyed on the roller conveyor, there will be lateral swaying, which makes it impossible for the cutting fluid to be accurately applied to the area to be cut, or even to be applied to the area to be cut, thus affecting the subsequent glass cutting effect.

[0022] The end of the aspiration section away from the bend section is connected to the liquid storage chamber, and the end of the connecting section away from the bend section is connected to each of the branch pipes;

[0042] Please refer to Figures 1 to 4As shown, this utility model proposes a coating device 100, which includes a base frame 1, at least two positioning components 2, and a coating head 3. The positioning component 2 includes a mounting plate 21, rollers 22, and elastic elements 23. The elastic elements 23 are disposed between the mounting plate 21 and the base frame 1 and are connected to the mounting plate 21 and the base frame 1. The rollers 22 are rotatably disposed on the mounting plate 21. The coating head 3 is connected to at least one mounting plate 21 and is configured to abut against the surface of the glass 8 and apply cutting fluid to the glass 8. Each elastic element 23 pushes against a roller 22 and rolls against one side of the glass 8, and at least two rollers 22 roll against two parallel sides of the glass 8.

[0043] In this embodiment, the base frame 1 is the main support structure of the coating device 100, which can be implemented by a metal frame or composite profile. It is used to fix and install the positioning component 2 and the coating head 3. The positioning component 2 refers to the mechanism for dynamically adjusting the position of the glass 8. At least two positioning components 2 are spaced apart on both sides of the glass 8 along the transmission direction. That is, at least one positioning component 2 is provided on one side of the glass 8 in the transmission direction. The at least two positioning components 2 together form a limiting channel in the same direction as the transmission direction of the glass 8 to limit the glass 8, especially the lateral swing of the glass 8.

[0044] Specifically, mounting plate 21 is used as the bearing base. Mounting plate 21 is slidably connected to base frame 1 through a guide mechanism. Mounting plate 21 is a plate-shaped component used to mount roller 22 and elastic element 23. It can be made of aluminum alloy or engineering plastic sheet. Its sliding connection structure allows roller 22 to move adaptively when glass 8 is laterally offset. Roller 22 uses a bearing structure to realize the rotation function. Elastic element 23 uses a helical spring, pneumatic push rod or elastic rubber to realize elastic connection. One end of elastic element 23 is fixed on base frame 1 and the other end is connected to mounting plate 21. The preload maintains the contact pressure of roller 22 when glass 8 swings on the side. When glass 8 swings, the displacement deviation is absorbed by elastic deformation. Roller 22 refers to the rolling part that contacts the side of glass 8. Roller 22 is mounted on mounting plate 21 through bearing and can rotate freely. It can be made of metal wheel with rubber-coated surface. Rotation reduces the frictional resistance with glass 8, and at the same time, it rolls freely in the transmission direction of glass 8 to limit lateral displacement.

[0045] In use, the applicator 100 is installed above the glass 8 conveyor line. Two positioning components 2 are located on either side of the glass 8. The elastic element 23 pushes the mounting plate 21, causing the roller 22 to contact the side of the glass 8. When the glass 8 begins to be conveyed, the roller 22 rolls along the side of the glass 8. If the glass 8 shifts laterally, the elastic element 23 will compress or extend to maintain contact between the roller 22 and the side of the glass 8. Simultaneously, the mounting plate 21 drives the applicator head 3 to follow the position change of the glass 8. The applicator head 3 always maintains contact with the surface of the glass 8, applying cutting fluid to the predetermined area.

[0046] In this embodiment, the applicator head 3 refers to the end effector that outputs the cutting fluid. The applicator head 3 is directly connected to the mounting plate 21, so that the position of the applicator head 3 is adjusted synchronously with the position of the roller 22. This ensures that the applicator head 3 is always aligned with the predetermined cutting area when the roller 22 swings with the glass 8. The applicator head 3 is made of a flexible material, specifically a porous sponge or fiber brush head, which can store a certain amount of cutting fluid. During the glass 8 transmission process, the applicator head 3 applies the cutting fluid to the surface of the glass 8 along the glass 8 transmission direction. Its installation position is linked with the roller 22, and synchronous displacement ensures that the cutting fluid accurately covers the area to be cut.

[0047] Understandably, in traditional glass cutting fluid coating processes, due to the inherent mechanical vibration of the conveying system and the inertia of the glass substrate, the glass substrate on the conveyor rollers experiences lateral displacement during longitudinal movement. This lateral displacement causes the cutting fluid coating trajectory to deviate from the preset path and exceed the dynamic following range of the cutting fluid coating head. The resulting coating position error directly leads to two technical defects: the cutting fluid cannot accurately cover the predetermined area of ​​the laser cutting path, and the coating width exceeds the process requirements, resulting in material waste.

[0048] Understandably, during operation, each elastic element 23 pushes a roller 22 to roll against one side of the glass 8, and at least two rollers 22 roll against the two parallel sides of the glass 8, so that the thrust generated by the elastic element 23 keeps the rollers 22 in close contact with the edge of the glass 8. The elastic element 23 drives the rollers 22 to clamp the two sides of the glass 8 to form a dynamic positioning. When the glass 8 swings laterally, the expansion and contraction characteristics of the elastic element 23 allow the mounting plate 21 to drive the rollers 22 to perform position compensation, maintaining stable contact pressure. The rotation design of the rollers 22 can reduce the frictional resistance with the glass 8, ensuring smooth transport of the glass 8. The two rollers 22 act on the two parallel sides of the glass 8 respectively, forming a symmetrical clamping effect, limiting the lateral displacement of the glass 8. Through the synergistic effect of the elastic element 23, rollers 22 and mounting plate 21, dynamic compensation for lateral displacement during the transport of the glass 8 is achieved, ultimately achieving the technical effect of accurately positioning the cutting fluid application position.

[0049] Meanwhile, when the glass 8 swings laterally, the elastic element 23 pushes the mounting plate 21 to drive the coating head 3 to shift synchronously, so that the cutting fluid coating path always matches the actual position of the glass 8, thereby eliminating the coating deviation caused by the displacement of the glass 8 during the transportation process.

[0050] Through the above solution, this application solves the problem that the cutting fluid cannot be accurately applied to the area to be cut due to the lateral swaying of the glass 8 during transportation. The application device 100 achieves dynamic compensation for the lateral displacement of the glass 8 through the elastic positioning component 2, ensuring that the application head 3 is always aligned with the predetermined cutting area. This design avoids the deviation of the cutting fluid application position and improves the accuracy of cutting fluid application. At the same time, the use of roller 22 reduces friction with the glass 8 and does not affect the normal transportation of the glass 8. In addition, the solution has a simple structure, does not require a complex electronic control system, and has good reliability and maintainability.

[0051] In one embodiment, such as Figure 1 and Figure 4 As shown, at least two rollers 22 are arranged at intervals relative to each other in a direction perpendicular to the glass 8; the applicator 100 includes at least two applicator heads 3, each applicator head 3 is connected to a mounting plate 21 and is arranged at intervals from a roller 22.

[0052] In this embodiment, the spacing of at least two rollers 22 along the direction perpendicular to the glass 8 can include: the spacing between the rollers 22 can be adjusted according to the width of the glass 8 to adapt to the conveying requirements of glass 8 of different specifications; the connection between each mounting plate 21 and the roller 22 can be fixed by bolts or by a snap-fit ​​structure to ensure a stable relative position between the roller 22 and the mounting plate 21; the spacing between the applicator head 3 and the roller 22 is to match the distance between the side of the glass 8 and the area to be cut, and at the same time, at least two applicator heads 3 abut against different surfaces of the glass 8, which can apply cutting fluid to different areas of the glass 8 so that the glass 8 can be cut in at least two areas, such as setting the applicator head 3 at the edge of the glass 8 adjacent to the roller 22 to cut the edge portion of the glass 8.

[0053] Understandably, during the transport of glass 8, when glass 8 swings laterally, the rollers 22, arranged perpendicular to the transport direction, are pushed by the elastic element 23, ensuring that the rollers 22 remain in close contact with both sides of glass 8, limiting the lateral displacement of glass 8 and maintaining its movement along a predetermined path. At this time, the applicator head 3, connected to the same mounting plate 21, maintains a fixed distance from the rollers 22, ensuring that the position of the applicator head 3 relative to the side of glass 8 remains constant after the side of glass 8 is limited by the rollers 22. This allows the applicator head 3 to automatically align with the area to be cut based on a preset distance. For example, when the distance between the rollers 22 is adjusted to 100 mm, the distance between the applicator head 3 and the rollers 22 is correspondingly adjusted to 15 mm. At this time, regardless of how the glass 8 shifts laterally, the applicator head 3 will always align with the area to be cut, 15 mm away from the side of glass 8. In addition, two applicator heads 3 are respectively arranged on the mounting plates 21 on both sides of the glass 8, which can simultaneously apply the cutting area on both sides, avoiding the problem of insufficient coverage caused by applying to only one side. Thus, this solution, through the vertical layout of the rollers 22 and the spacing of the applicator heads 3, ensures accurate application of the cutting fluid while dynamically correcting the position of the glass 8, and solves the problem of application deviation caused by the swing of the glass 8.

[0054] Through the above technical solution, this application effectively limits the lateral sway of the glass 8 during transmission by arranging at least two rollers 22 relatively spaced apart along a direction perpendicular to the glass 8's transport direction. Simultaneously, by providing at least two application heads 3 and connecting them to corresponding mounting plates 21, with each application head 3 spaced apart from the rollers 22 on the same mounting plate 21, it ensures that the application head 3 can accurately align with the area to be cut. This design not only improves the accuracy of cutting fluid application but also expands the application coverage area, effectively solving the problem that a single application head 3 cannot cover the areas to be cut on both sides of the glass 8. Therefore, the cutting fluid application position is more precise, improving the quality and efficiency of subsequent glass 8 cutting.

[0055] In one embodiment, such as Figure 1 and Figure 4 As shown, the base frame 1 includes a main frame 11 and at least two mounting seats 12, which are opposite to and spaced apart from each other on the main frame 11; each elastic element 23 is connected to a mounting plate 21 and a mounting seat 12, and each mounting plate 21 is slidably connected to a mounting seat 12.

[0056] In this embodiment, the main frame 11 is constructed as a frame structure with a support positioning component 2 and an applicator head 3. The mounting bases 12 are symmetrically distributed on both sides of the main frame 11. The mounting bases 12 and the main frame 11 can be connected by bolts or welded. The elastic element 23 can be a compression spring, with one end abutting against the inner surface of the mounting base 12 and the other end acting on the end face of the mounting plate 21. The mounting plate 21 and the mounting base 12 can be slidably connected by a slide rod 122 cooperating with a guide hole. Alternatively, the mounting base 12 is provided with a slide rail, and the mounting plate 21 is slidably connected to the slide rail. On the one hand, the spacing of the mounting bases 12 can be adjusted based on the width of the glass 8. On the other hand, it can also cooperate with the elastic element 23 to achieve dynamic contact between the roller 22 and the side of the glass 8.

[0057] Specifically, the main frame 11 serves as a supporting base, providing a fixed reference for the mounting base 12. The two mounting bases 12 form separate mounting points on both sides of the main frame 11. When the glass 8 shifts laterally during transport, the mounting plate 21 slides along the axis of the slide rod 122 under the push of the elastic element 23. The clearance fit between the slide rod 122 and the guide hole restricts the swaying of the mounting plate 21 perpendicular to the sliding direction. The thrust generated by the elastic element 23 is directly transmitted to the mounting plate 21 through the mounting base 12, preventing deformation of the main frame 11 from causing this. When the thrust direction shifts, for example, when the glass 8 shifts to the left, the left mounting plate 21 drives the roller 22 to retract along the slide bar 122, while the right mounting plate 21 remains in its original position. The independent action of the elastic elements 23 on both sides makes the contact force of the roller 22 on both sides of the glass 8 dynamically balanced. Thus, the mounting plate 21 maintains a stable trajectory during the sliding process. The extension and retraction stroke of the elastic element 23, combined with the guiding effect of the slide bar 122, ensures that the roller 22 always contacts the side of the glass 8 with uniform pressure, thereby improving the positioning accuracy and the adaptability of the glass 8 position.

[0058] Understandably, this application optimizes the connection structure between the mounting plate 21 and the base frame 1. The base frame 1 is decomposed into the main frame 11 and the mounting base 12, forming a stable split mounting point to ensure symmetrical force distribution on both sides of the positioning components 2. The elastic element 23 connects the mounting plate 21 and the mounting base 12, directly linking the extension and retraction direction of the elastic element 23 with the fixed position of the mounting base 12, avoiding force deviation caused by overall deformation of the base frame 1. The sliding connection design between the mounting plate 21 and the mounting base 12 allows the mounting plate 21 to adaptively adjust its position under the action of the elastic element 23, adapting to the slight offset of the side of the glass 8, while limiting the degree of freedom of the mounting plate 21 in the non-sliding direction, improving the positioning stability and position adjustability of the roller 22 on the side of the glass 8, ensuring uniform distribution of the abutment pressure of the roller 22 on the side of the glass 8, and improving positioning accuracy.

[0059] In one embodiment, such as Figure 2As shown, the mounting base 12 includes a base body 121 and a slide rod 122. The base body 121 is located on the main frame 11. The mounting plate 21 is provided with a guide hole. One end of the slide rod 122 is connected to the base body 121, and the other end of the slide rod 122 passes through the guide hole. The elastic element 23 is sleeved on the slide rod 122 and is limited between the mounting plate 21 and the base body 121.

[0060] In this embodiment, the base 121 and the main frame 11 can be rigidly connected by bolts to form a fixed base. The slide rod 122 can also be a guide post structure, with its axis perpendicular to the transmission direction of the glass 8. The inner diameter of the guide hole can be set to be slightly larger than the diameter of the slide rod 122 to form a clearance fit. The elastic element 23 can be a compression spring, and the ratio of its free length to the length of the slide rod 122 is controlled within the range of 0.6-1.2. A guide hole is opened on the mounting plate 21 to slide and connect with the slide rod 122, so that one end of the slide rod 122 is connected to the base 121, and the other end of the slide rod 122 is limited and passes through the guide hole.

[0061] Specifically, when the glass 8 contacts the roller 22 and generates lateral pressure, the mounting plate 21 moves linearly along the axis of the slide rod 122 and compresses the elastic element 23 located between the mounting plate 21 and the seat 121. During the compression process, the spiral structure of the elastic element 23 always contracts coaxially around the outer wall of the slide rod 122, effectively avoiding the lateral force caused by the bending of the spring. A limiting boss can be provided at the end of the slide rod 122 to abut against the side of the mounting plate 21 facing away from the seat 121, controlling the maximum displacement stroke of the mounting plate 21 within the range of 20-50 mm. This ensures sufficient elastic buffer space, prevents excessive compression and damage to the elastic element 23, and prevents the mounting plate 21 from detaching from the seat 121 when the roller 22 is not in contact with the glass 8. Through the precision motion pair formed by the slide rod 122 and the guide hole, the vertical force angle deviation of the roller 22 on the side of the glass 8 can be controlled within ±0.5°, achieving precise application of the cutting fluid along a predetermined trajectory.

[0062] Understandably, this application provides a rigid guide structure that effectively solves the problem of lack of rigid guidance in the sliding connection between the mounting plate 21 and the mounting base 12. The slide rod 122 and the guide hole form a precise linear kinematic pair, which not only ensures the axial displacement freedom of the mounting plate 21 under the action of the elastic member 23, but also eliminates the possibility of lateral sway of the mounting plate 21. The arrangement of the elastic member 23 sleeved on the slide rod 122 utilizes the rigidity of the slide rod 122 to maintain the stability of the compression direction of the elastic member 23 and avoids radial twisting of the elastic member 23 during compression. At the same time, the cooperation between the slide rod 122 and the guide hole forms a double limiting structure, which constrains the maximum compression stroke of the elastic member 23 and ensures that the elastic force is always transmitted along the axial direction of the slide rod 122. This structural design enables the roller 22 to maintain a vertical force state when contacting the side of the glass 8, thereby improving the positioning accuracy and reliability of the glass 8.

[0063] In one embodiment, such as Figure 1 and Figure 4 As shown, the coating device 100 also includes a liquid storage tank 4 and a transmission pipeline 5. The liquid storage tank 4 is provided with a liquid storage cavity 41, which is configured to store cutting fluid. The transmission pipeline 5 is located on the base frame 1 and is located at the upper part of the coating head 3 in the vertical direction. One end of the transmission pipeline 5 is connected to the liquid storage cavity 41, and the other end of the transmission pipeline 5 abuts against the coating head 3 to deliver cutting fluid to the coating head 3.

[0064] In this embodiment, the liquid storage chamber 41 stores the cutting fluid to be applied to the surface of the glass 8. The transmission pipeline 5 can be a flexible or rigid pipe to ensure a balance between flow resistance and delivery efficiency. The liquid storage tank 4 can be fixed on the top of the base frame 1 and is detachably connected to the transmission pipeline 5 through a threaded interface for easy maintenance. Since the application head 3 is made of a flexible or porous material, the transmission pipeline 5 directly abuts against the application head 3 to directly transmit the cutting fluid to the application head 3 and allow the application head 3 to directly apply the cutting fluid to the surface of the glass 8. When the base frame 1 is vibrated, the transmission pipeline 5 absorbs the mechanical impact through the bend section 512 to prevent liquid leakage.

[0065] Specifically, the cutting fluid stored in the reservoir 4 is gravity-transmitted to the applicator head 3 via the transmission pipe 5. Since the transmission pipe 5 is located above the applicator head 3, the liquid flows naturally under gravity, requiring no additional power. The reservoir 41 and the transmission pipe 5 form a closed circuit, preventing external contaminants from entering. The end of the transmission pipe 5 is in physical contact with the applicator head 3, forming a directional delivery channel to prevent liquid deviation. When the applicator head 3 moves with the mounting plate 21, the expansion and contraction of the elastic element 23 compensates for positional fluctuations on the side of the glass 8. The transmission pipe 5, made of flexible material, adapts to the displacement of the applicator head 3, maintaining a stable liquid supply. The liquid level difference in the reservoir 4 provides constant pressure, and the flow rate is controlled in conjunction with the pipe's inner diameter, ensuring uniform liquid output from each applicator head 3. When it is necessary to adjust the liquid supply, the pipe cross-sectional area can be changed via a regulating valve, for example, by controlling the valve opening within the 30%-80% range to achieve precise flow control.

[0066] Understandably, the combination of the reservoir 4 and the delivery line 5 ensures a continuous and stable supply of cutting fluid. The reservoir 4 provides ample cutting fluid reserves, avoiding the need for frequent replenishment, while the delivery line 5 ensures that the cutting fluid is accurately delivered to the application head 3, guaranteeing the continuity of the application process.

[0067] Through the above technical solution, this application solves the problem that the application of cutting fluid may be interrupted or uneven due to unstable fluid supply during continuous operation of the coating head 3. The introduction of the storage tank 4 and the transmission pipeline 5 constructs a complete cutting fluid storage and delivery system, ensuring that the cutting fluid can be stably and continuously supplied to the coating head 3. This design not only improves the continuity and uniformity of the coating process, but also reduces the interruption of operation caused by fluid supply problems, thereby improving the consistency of glass 8 cutting quality. In addition, due to the adoption of gravity delivery, the dependence on external power is reduced, the system structure is simplified, and the reliability and maintenance convenience of the equipment are improved.

[0068] In one embodiment, such as Figure 1 and Figure 4 As shown, the applicator 100 includes a plurality of applicator heads 3, which are connected to at least two mounting plates 21 arranged opposite to each other; the transmission pipeline 5 includes a main pipeline 51 and a plurality of branch pipelines 52, one end of the main pipeline 51 is connected to the liquid storage chamber 41, and the other end of the main pipeline 51 is connected to each branch pipeline 52, and the end of each branch pipeline 52 away from the main pipeline 51 is abutted against an applicator head 3.

[0069] In this embodiment, one end of the main pipeline 51 is connected to the liquid storage chamber 41 by a threaded connection, and the other end is provided with a distributor. The distributor has multiple interfaces, each of which is connected to a branch pipeline 52. The other end of each branch pipeline 52 is connected to the application head 3 through a quick connector. Furthermore, the main pipeline 51 can be installed on the top of the base frame 1, and the branch pipelines 52 extend vertically downward along the base frame 1 to each application head 3. In order to ensure the uniform distribution of cutting fluid, a flow regulating valve can be installed at the connection between the main pipeline 51 and the branch pipelines 52 to regulate the flow rate of each branch pipeline 52. Each mounting plate 21 is connected to at least one application head 3.

[0070] Thus, the cutting fluid is transported from the reservoir 41 to the distributor via the main pipeline 51, and then to each applicator head 3 via multiple branch pipelines 52. This design ensures that each applicator head 3 receives a stable supply of cutting fluid and that there is no pressure unevenness due to location differences.

[0071] The diameter of the main pipe 51 is set to be larger than that of the branch pipe 52 to match the flow output requirements of the liquid storage chamber 41. The inner wall of the branch pipe 52 can be made into a smooth surface to reduce fluid resistance, such as stainless steel or a polymer material with polished inner wall, so as to maintain the consistency between the internal pressure of the branch pipe 52 and the pressure at the end of the main pipe 51. Multiple branch pipes 52 are connected in parallel at the end of the main pipe 51. The connection nodes between each branch pipe 52 and the main pipe 51 are configured to be symmetrically distributed, such as equidistantly arranged along the axial direction of the main pipe 51 or distributed in a ring array, so as to avoid different pressure losses between the branch pipes 52 due to length differences. The length of the branch pipe 52 can be controlled within the range of 50-200 mm to shorten the response time of the cutting fluid delivery path.

[0072] Understandably, the main pipe 51 extends from the reservoir 41 to a position near the applicator head 3, forming a branch node at its end. Multiple branch pipes 52 are led out from the branch node and extend independently to their respective applicator heads 3. After the cutting fluid is delivered to the branch node at a constant pressure in the main pipe 51, it is synchronously distributed to different applicator heads 3 through each branch pipe 52. Since there is no series or cross connection between the branch pipes 52, the internal pressure of each branch pipe 52 depends only on the pressure at the branch node. The pressure at the branch node is kept stable through the connection between the main pipe 51 and the reservoir 41. When the glass 8 swings laterally, the elastic element 23 pushes against the mounting plate 21, causing the applicator head 3 to move. At this time, the branch pipes 52 are connected to the applicator head 3 through flexible materials or movable joints, thereby maintaining a constant pressure in the branch pipes 52 during the change of position of the applicator head 3. The cutting fluid is output at the same flow rate in each branch pipe 52, so that the applicator head 3 at different positions obtains a consistent amount of cutting fluid on the surface of the glass 8, thereby eliminating the problem of uneven application caused by differences in delivery pressure.

[0073] Through the above technical solution, this application achieves uniform distribution of cutting fluid to multiple applicator heads 3. The main pipeline 51 serves as the main delivery channel, providing a unified fluid supply pressure basis for each branch pipeline 52. Multiple branch pipelines 52 are independently connected to their corresponding applicator heads 3, avoiding pressure interference between different branch pipelines 52. This structural design ensures that each applicator head 3 receives a consistent supply of cutting fluid in different installation positions, effectively guaranteeing the uniformity of cutting fluid application across all areas to be cut on the glass 8 surface. Even when the glass 8 is laterally swaying, a stable cutting fluid application effect can be maintained, improving the consistency and reliability of cutting quality.

[0074] In one embodiment, such as Figure 1 and Figure 3As shown, the main pipeline 51 includes a suction section 511, a bend section 512, and a connecting section 513. The bend section 512 is located between the suction section 511 and the connecting section 513 and is connected to both the suction section 511 and the connecting section 513. The end of the suction section 511 away from the bend section 512 is connected to the liquid storage chamber 41, and the end of the connecting section 513 away from the bend section 512 is connected to each branch pipeline 52. The vertical height of the bend section 512 is higher than that of the suction section 511 and the connecting section 513.

[0075] In this embodiment, the suction section 511 and the connecting section 513 can be straight pipe structures. One end of the suction section 511 is connected to the bottom of the liquid storage chamber 41, and the other end is connected to the bend section 512. The suction section 511 can be located inside the liquid storage chamber 41 and extend to the bottom of the liquid storage chamber 41 to facilitate the suction of cutting fluid. The bend section 512 can be U-shaped or arc-shaped, with its highest point higher than the suction section 511 and the connecting section 513. The connecting section 513 can be an inclined pipe structure, with one end connected to the bend section 512 and the other end connected to the branch pipe 52. The highest point of the bend section 512 can be located above the liquid surface in the liquid storage chamber 41 to ensure the formation of a siphon effect.

[0076] The bending section 512 is configured as a structural support point for the siphon effect, and its highest point forms a height difference with the liquid surface in the liquid storage chamber 41. The suction section 511 adopts an inclined or vertically extended tube structure. The connecting section 513 and the branch pipe 52 are connected by a tee joint or a branch pipe to achieve multi-directional flow. The number of branch pipes 52 can be 2-4 sets to adapt to different applicator head 3 layouts. The connection between the bending section 512 and the suction section 511 and the connecting section 513 adopts an arc transition to reduce fluid resistance.

[0077] Specifically, when the liquid level in the storage chamber 41 is lower than that in the bend section 512, the bend section 512, as the highest point of the pipeline, forms the siphon start condition. When the cutting fluid is injected for the first time, the liquid rises through the suction section 511 to the bend section 512 and flows into the connecting section 513 under the action of gravity. At this time, a negative pressure area is formed at the apex of the bend section 512, continuously drawing the liquid in the storage chamber 41 upward. During continuous transportation, the bend section 512 maintains the pressure difference required for siphoning, so that the liquid can be pumped without the need for an external pump. The entire flow from the storage chamber 41 to the branch pipe 52 is completed. The structure of the bend section 512 being higher than the connecting section 513 gives the liquid the potential energy to flow downwards before entering the branch pipe 52. For example, the vertical height difference between the bend section 512 and the inlet of the branch pipe 52 is 50-100 mm, ensuring that the outlet pressure of each branch pipe 52 is balanced. This layout also prevents the liquid from accumulating in the low-lying areas of the pipe due to its own weight. For example, when the machine is stopped, the height difference at the top of the bend section 512 causes the residual liquid to automatically flow back to the storage chamber 41.

[0078] It is understood that this application can utilize the spatial layout of the bend section 512 being higher than the suction section 511 and the connecting section 513 to form a natural flow path for the liquid. The bend section 512, as the highest point in the pipeline, guides the cutting fluid from the storage chamber 41 through the suction section 511 to the bend section 512 by gravity, and then flows downward into the connecting section 513 and the branch pipeline 52. This avoids backflow or residue in the pipeline due to the weight of the liquid itself. This structure ensures that the cutting fluid always fills the pipeline and reduces air bubble retention during transportation, thereby improving the continuity and stability of liquid transportation. By utilizing the siphon principle, cutting fluid is directly drawn from the storage chamber 41 and transmitted to each branch pipe 52 without the need for external power, saving energy. At the same time, the suction section 511 is responsible for drawing liquid from the bottom of the storage chamber 41, the bending section 512 forms a siphon effect through the height difference, and the connecting section 513 uses gravity to evenly distribute the liquid to each branch pipe 52, thereby ensuring that multiple application heads 3 receive a stable supply of cutting fluid simultaneously. This solves the problem of cutting fluid not being able to be smoothly delivered when the storage tank 4 is low or there is a height difference in the pipeline.

[0079] In one embodiment, such as Figure 1 and Figure 3 As shown, the applicator 100 also includes a first regulating valve 6, which is located in the transmission pipeline 5 and between the liquid storage chamber 41 and the applicator head 3. The first regulating valve 6 is configured to regulate the speed at which the cutting fluid is delivered to the applicator head 3.

[0080] In this embodiment, the transmission pipeline 5 is configured as a multi-stage delivery structure consisting of a main pipeline 51 and branch pipelines 52. The main pipeline 51 connects to the liquid storage chamber 41, and the branch pipelines 52 are connected to the end of the main pipeline 51 and lead to each applicator head 3. The first regulating valve 6 can be installed at the connecting section 513 of the transmission pipeline 5, for example, at the beginning of the connecting section 513 downstream of the bend section 512. The valve opening is controlled manually or electrically to adapt to different glass 8 sizes and cutting fluid requirements. When the cutting fluid flow rate in the main pipeline 51 changes due to changes in the liquid level in the liquid storage chamber 41 or fluctuations in the pumping pressure, adjusting the opening of the first regulating valve 6 can stabilize the total flow output of the main pipeline 51, thereby reducing the pressure difference between the branch pipelines 52.

[0081] Specifically, the cutting fluid is pumped from the storage chamber 41 through the suction section 511 to the bend section 512, which is higher than other parts of the pipeline to create a gravitational potential energy difference. A first regulating valve 6 is installed at the inlet of the connecting section 513 downstream of the bend section 512, controlling the flow rate of the cutting fluid into the connecting section 513 by adjusting the valve opening. For example, when a pressure drop is detected at the end of the branch pipe 52, the opening of the first regulating valve 6 can be increased to 70% to increase the flow rate and maintain the pressure in the main pipeline 51 within the range of 0.2-0.3 MPa. Because the flow rate in the main pipeline 51 is stably regulated, resistance fluctuations caused by length differences in the branch pipe 52 are suppressed, and the deviation in the cutting fluid supply obtained by each applicator head 3 within the same time unit can be controlled within ±5%. As a result, the uniformity of the cutting fluid coverage on the glass surface to be cut is improved, and the yield of subsequent cutting processes is increased to over 95%.

[0082] Understandably, this application can achieve total flow regulation of the cutting fluid delivery system through a single control node, maintaining dynamic pressure balance within the main pipeline 51. When the glass 8 swings laterally, causing pressure fluctuations in each branch pipeline 52, the stable regulation of the total flow can buffer the impact of sudden pressure changes on the flow rate of the branch pipeline 52, thereby reducing the difference in liquid output speed of each applicator head 3 caused by drastic changes in the flow rate of the main pipeline 51. Furthermore, it forms a collaborative control system with the independent adjustment device of the branch pipeline 52, ensuring the flexibility of fine-tuning the flow of each branch while avoiding system pressure imbalance caused by excessive or insufficient total flow, ultimately achieving uniform coverage of the cutting fluid on the surface of the glass 8 in the area to be cut.

[0083] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the applicator 100 also includes a plurality of second regulating valves 7. Each second regulating valve 7 is provided on a branch pipe 52 and is located between the end of the branch pipe 52 connected to the main pipe 51 and the applicator head 3. The second regulating valve 6 is configured to regulate the speed at which the cutting fluid is delivered to the applicator head 3.

[0084] In this embodiment, the applicator 100 also includes multiple second regulating valves 7. The second regulating valves 7 can be needle valves, ball valves, or proportional regulating valves. The valve body is connected to the branch pipe 52 via flanges or threads. The control end of each regulating valve can be connected to an independent actuator. The actuator receives the flow sensor signal and controls the flow fluctuation of the branch pipe 52 within ±5%. When the flow resistance of the branch pipe 52 increases due to the increased bending angle, the opening of the corresponding regulating valve can be increased by 10%-15% to compensate for the pressure loss. The first regulating valve 6 of the main pipe 51 controls the total flow to a constant value. At this time, the second regulating valves 7 of each branch pipe 52 can make a ±30% flow fine adjustment based on the constant total flow of the main pipe 51.

[0085] During the cutting fluid delivery process, the cutting fluid in the storage chamber 41 is distributed to multiple branch pipes 52 via the main pipe 51. Due to the difference in length of the branch pipes 52, when a branch pipe 52 has many right-angle bends, the straighter pipes will have increased flow resistance. At this time, the flow rate of the branch pipe 52 can be adjusted by the second regulating valve 7 located on the branch pipe 52, avoiding the global flow fluctuation caused by the traditional single regulating valve changing the total flow. This graded regulation mechanism ensures that the main pipe 51 maintains a stable flow state, and each branch pipe 52 is regulated independently without interference. Ultimately, it ensures that the error in the amount of cutting fluid delivered by each coating head 3 per unit time is less than 3%, and the uniformity of the cutting fluid film thickness formed on the glass surface is controlled within ±0.05 mm.

[0086] It is understandable that due to differences in liquid flow resistance in different branch pipes 52 or uneven working pressure of the coating head 3, the flow rate of cutting fluid delivered from each branch pipe 52 to the corresponding coating head 3 cannot be independently adjusted, thus affecting the uniformity of the cutting fluid coating on the glass 8 surface by each coating head 3. This application effectively eliminates the problem of uneven cutting fluid distribution caused by differences in pipe resistance, ensuring that each coating head 3 receives an equal and stable supply of cutting fluid. The independent control mechanism of the second regulating valve 7 allows the operator to compensate for pressure loss caused by pipe deformation or installation errors in real time, maintaining the flow balance between different workstations. The graded flow control system realizes the overall flow control of the main pipe 51 while retaining the fine-tuning capability of the branch pipes 52, enabling the system to quickly establish a stable fluid distribution state when dealing with different glass 8 sizes or processing speeds, ultimately ensuring that the uniformity of the cutting fluid coating on the glass 8 surface meets the process standards.
