Screen glass edge grinding equipment

Abstract

This invention discloses a screen display glass edge grinding device, comprising a positioning platform, a traversing unit that drives the positioning platform to move laterally along the grinding path, and grinding units located on both sides of the grinding path. On one hand, this invention utilizes an arc-shaped obstruction zone formed by an air knife to block the grinding section. Water jets generate first and second fluids that pass through the grinding section and respectively adhere to the grinding grooves of the grinding wheel and the glass surface, throwing waste material towards a waste collection unit. This effectively reduces the probability of waste splashing and residue, improves grinding quality, increases waste collection rate, reduces accumulation, and significantly reduces cleaning frequency. On the other hand, based on the cooperation of the grinding units on both sides, grinding is carried out synchronously during the traversal of the positioning platform, and the lateral forces generated by them cancel each other out, effectively improving the stress distribution on the glass and reducing the probability of glass deformation and damage. Furthermore, it can simultaneously perform bilateral or diagonal synchronous grinding, effectively improving grinding efficiency.

Description

Technical Field

[0001] This invention belongs to the field of glass processing technology, and specifically relates to a screen display glass edge grinding equipment. Background Technology

[0002] In the processing of display glass, the long sides, short sides, and four corners of the glass need to be ground to eliminate stress after cutting and remove sharp edges and foreign objects. Therefore, a glass edge grinding and chamfering machine is required. For example, Chinese Patent No. CN118595942B discloses a glass substrate grinding device, which includes a grinding shell and a water jet. The grinding shell has a through groove formed along a first horizontal direction, suitable for the continuous passage of one side of the glass substrate. A grinding wheel is provided inside the grinding shell. A negative pressure interface is provided on one side of the grinding shell. The negative pressure interface is used to connect external equipment and maintains a negative pressure state inside the grinding shell. The grinding shell is equipped with an upper air knife, with a first air outlet on its inward-facing side along a second horizontal direction, used to blow air onto one side of the upper surface of the glass substrate. The grinding shell is also equipped with a lower air knife, with a second air outlet on its inward-facing side along a second horizontal direction, used to blow air onto one side of the lower surface of the glass substrate. The lower and upper air knives are symmetrically arranged vertically at both ends of the through-slot. An upper water jet is used to spray water onto the upper surface of the grinding area of ​​the glass substrate. In other words, by employing a combination of through-slot, negative pressure interface, and water jet in the glass substrate grinding device, the problem of grinding water overflow is solved, ensuring that the grinding water remains within the grinding area, thus improving the grinding quality of the glass substrate and the quality of subsequent processing.

[0003] However, the following technical defects exist in the above implementation process:

[0004] 1) The water jet used is a straight type, and during the grinding process, the grinding section is only formed between the grinding groove and the glass contact part. Therefore, the water generated by the water jet can only rush towards the surface of the grinding wheel and cannot enter the grinding section. At the same time, under the interception of the water jet, some grinding waste is splashed into the grinding shell, and the rest is thrown to the negative pressure port for extraction. Therefore, not only can the glass edge of the grinding section be ground synchronously in the flowing water, but the water flow generated by the water jet cannot carry the grinding waste to the negative pressure port. At the same time, a large amount of waste residue will remain on the inner wall of the grinding shell. Once it falls on the grinding wheel, it will affect the grinding quality. Moreover, it requires frequent disassembly and cleaning, which is time-consuming and labor-intensive.

[0005] 2) The air knife used is also straight-line type. Its main function is to form another isolation wall to prevent water and debris from splashing and causing damage to the glass surface. However, the isolation range is limited (water and debris splash out in the straight line direction formed by the air knife).

[0006] 3) Typical display glass is basically rectangular, while conventional grinding involves grinding only one side or corner of the glass. This is not only cumbersome and inefficient, but also causes uneven stress on one side of the glass during grinding, which can lead to deformation or damage. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide an improved screen glass edge grinding device.

[0008] To achieve the above objectives, the present invention adopts the following solution:

[0009] A screen display glass edge grinding device includes a positioning platform, a traversing unit that drives the positioning platform to move laterally along a grinding path, and grinding units located on both sides of the grinding path. Each grinding unit includes a grinding seat and a grinding wheel. The grinding seat has a glass inlet, an air knife, and a water knife. The grinding wheel has grinding grooves formed from its circumference. The two grinding units are relatively shifted and adjusted along the width of the grinding path, and the lateral forces generated by the two grinding units simultaneously grinding the opposite sides of the glass edges or corners cancel each other out. The air knife forms an arc-shaped obstruction zone with the center of the grinding wheel as a reference, through which the glass is inserted. The glass inlet abuts against the grinding groove from the edge or corner to be ground to form a grinding section located within the barrier area and having a first end and a second end; a waste collection section is also formed on the grinding base, which is aligned with the second end; the water jet outlet is located within the barrier area and aligned with the first end; the water jet forms a first fluid and a second fluid; the first fluid is thrown from the inside of the first end, adhering to the grinding groove as a reference, through the grinding section and towards the waste collection section; the second fluid, based on the air knife barrier, washes the glass surface from the outside of the first end as the grinding wheel rotates, and the waste formed by the washing is thrown towards the waste collection section.

[0010] According to a specific embodiment and preferred aspect of the present invention, a grinding chamber is formed in the grinding seat, and a grinding wheel is inserted into the grinding chamber vertically; the glass inlet is connected to one side of the grinding chamber and is arranged through the grinding path, wherein the grinding part of the grinding wheel intersects with the inner side of the glass inlet to form a grinding area, and the glass moves laterally along the grinding path while keeping the edge or corner to be ground through the grinding area.

[0011] Preferably, the grinding base includes a first base body and a second base body forming a grinding chamber; the air knife includes upper and lower air knives disposed outside the second base body and spaced apart to form glass inlets; a clearance notch is formed on the second base body to avoid the grinding wheel, and the collection ports of the water jet and waste collection section are disposed on the second base body and located on opposite sides of the clearance notch along the grinding path. In this arrangement, under the obstruction formed by the upper and lower air knives, the fluid flushed out by the water jet flows rapidly to the waste collection section for collection due to its own inertia, the rotation of the grinding wheel, and the transport of the glass, significantly reducing the probability of waste remaining in the grinding area.

[0012] Preferably, in the orthographic projection on the horizontal plane, when the glass is inserted for grinding, the two ends of the upper and lower air knives intersect with the two sides of the edge or corner of the glass to be ground, respectively; and / or, in the orthographic projection on the horizontal plane, the center lines of the air outlets of the upper and lower air knives and the grinding wheel coincide; and / or, in the orthographic projection on the horizontal plane, the space between the upper and lower air knives and the grinding wheel gradually narrows from both ends towards the middle. This not only reduces the area of ​​the grinding section, enhancing the aggregation and collection capacity of waste materials, but also allows the glass edge to form a section to be ground and a section already ground outside the barrier zone during grinding. Before and after grinding, the airflow blown from the upper and lower air outlets protruding from the edge to be ground can converge to quickly isolate the waste material to prevent it from escaping, reducing interference with the section to be ground and the section already ground.

[0013] Preferably, the upper and lower air knives each form an air inlet chamber, an airflow channel, and an air outlet that are sequentially connected from the inside out, wherein both the upper and lower airflow channels are gradually narrowed towards the air outlet; and / or, the air outlets of the upper and lower air knives include a first arc-shaped segment corresponding to the bottom surface of the upper air knives and the top surface of the lower air knives, and two second arc-shaped segments corresponding to the inner surfaces of the upper and lower air knives and located on opposite sides of the grinding area, wherein the two second arc-shaped segments are connected to the two ends of the first arc-shaped segment, and the airflow blown by the upper and lower first and second arc-shaped segments cooperate to form a barrier area covering the grinding area; and / or, a venting channel extending vertically and communicating with the clearance notch is formed between the lower air knives and the second base. Here, residual waste on the lower surface of the glass is discharged through the venting channel to avoid the accumulation of residue from obstructing the movement or grinding of the glass.

[0014] Preferably, the second housing has an outlet communicating with the water jet and located within the obstruction zone, and a guide portion extending from the outside of the outlet towards the grinding section. The contact point between the fluid ejected from the outlet and the grinding wheel is located on the side of the first end away from the second end. A guide zone that gradually narrows towards the grinding section is formed between the guide portion and the grinding wheel, and the fluid ejected from the water jet flows along the guide zone towards the first end. This facilitates the convergence of the fluid after ejection, thereby enhancing the scouring effect on the grinding section. Simultaneously, it enables pre-cooling and cooling of the grinding wheel before and during grinding, ensuring the stability of the grinding temperature and improving the grinding effect.

[0015] Preferably, the first housing includes an upper split and a lower split arranged vertically, wherein a return chamber is formed between the upper split and the second housing, communicating with the second end, and the lower split forms a slow-flow chamber communicating with the bottom of the return chamber; the waste collection section includes a main collection branch pipe communicating with the return chamber and an auxiliary collection branch pipe communicating with the slow-flow chamber. The waste generated during grinding enters the return chamber from the second end, and part of the waste is collected through the main collection branch pipe and the other part is collected through the auxiliary collection branch pipe. Here, based on the cooperation of the main and auxiliary collection branch pipes, the waste rushing out from the second end is diverted and collected smoothly, further reducing the splashing and accumulation of waste impacting the inner wall of the grinding chamber.

[0016] Preferably, the reflux chamber is located close to the grinding wheel, and has a reflux port on one side that matches the outer contour of the portion of the grinding wheel near the second end, and a main collection hole on the opposite side that communicates with the main collection branch pipe. Inside the reflux chamber, there is a first guide channel extending from the reflux port along the direction of the fluid flowing out from the second end, and a second guide channel extending from the end of the first guide channel away from the second end around the center of the grinding wheel. The bottom of each end of the second guide channel forms an auxiliary collection hole communicating with the slow-flow chamber. Here, based on the air knife's obstruction, the waste material ejected from the second end undergoes centrifugal motion and enters the reflux chamber, flowing along the inner wall of the reflux chamber. This reduces splashing caused by impacting the inner wall of the reflux chamber, achieving stable waste collection and preventing residue on the inner wall of the reflux chamber.

[0017] Preferably, the two ends of the second guide channel each have an arc-shaped inner wall extending around the centerline of the corresponding auxiliary collection hole; and / or, the main collection branch pipe and the auxiliary collection branch pipe can respectively create negative pressure in the return chamber and the slow flow chamber; and / or, the bottom of the slow flow chamber extends vertically and vertically, wherein the connection point of the auxiliary collection branch pipe on the slow flow chamber is close to the lower edge of the bottom of the chamber, and the grinding area is located above the upper edge of the bottom of the chamber; and / or, the bottom of the slow flow chamber also forms a slow flow groove that connects one-to-one with the inlet of multiple auxiliary collection branch pipes. Here, complete collection of fine dust and droplets generated during grinding is ensured; at the same time, the slow flow groove design allows waste material to converge in the slow flow groove during flow and be discharged, avoiding the problem of insufficient liquid content and insufficient fluidity leading to the inability of solids to be discharged.

[0018] According to another specific embodiment and preferred aspect of the invention, the positioning platform employs a suction cup, onto which the display glass is adsorbed and protrudes outwards from all sides; and / or, the lateral movement unit includes a lateral movement actuator that drives the positioning platform to reciprocate along the grinding path, and a rotary drive that drives the positioning platform to rotate about a vertical centerline. Here, grinding is completed by the lateral movement actuator, and the rotary drive is used to switch the side or corner of the glass to be ground for alignment with the grinding unit.

[0019] According to another specific embodiment and preferred aspect of the present invention, the edge grinding equipment further includes a centering unit, which includes a centering platform, a centering actuator, and a transfer robot. The glass is laid flat on the upper surface of the centering platform, and a plurality of clearance grooves are formed on the centering platform around the glass. Each clearance groove extends from the outside to the inside and its inner end is located directly below the glass. The centering actuator includes a plurality of push rods corresponding one-to-one with the plurality of clearance grooves and a power component that drives each push rod to reciprocate along the corresponding clearance groove. Each push rod on each side forms point or line contact with the corresponding side of the glass. The plurality of push rods retract inward along the clearance groove with the center line of the centering platform as a reference and clamp the glass around its perimeter. The center line of the glass then coincides with the center line of the centering platform. The transfer robot is used to transfer the centered glass to the positioning platform. Here, based on the multi-directional clearance grooves formed on the centering platform that extend into the bottom of the glass, the glass is centered by multiple push rods retracting inward along the clearance grooves, which meets the needs of center positioning and clamping of glass of various specifications and is highly practical. At the same time, by forming point or line contact between each push rod and the side of the glass, the resistance generated by the glass under clamping can be effectively reduced, the probability of glass deformation can be significantly reduced, and the material handling accuracy can be improved, so that the glass can be transferred to the positioning platform for precise grinding of the sides and corners.

[0020] Preferably, the extension direction of each clearance groove is perpendicular to the extension direction of the corresponding glass side; the centering platform is rectangular, and multiple clearance grooves on each side extend inward from the corresponding side of the centering platform and are flush at their inner ends.

[0021] Preferably, the upper surface of the centering platform is divided into a first region located between the inner ends of multiple clearance grooves and a second region located around the first region. During material placement, the glass is placed from the center into the first region, extends into the second region from the side, or protrudes outward from the second region. In the orthographic projection on the horizontal plane, the area of ​​the first region is S1, the area of ​​the centering platform is S2, and the area of ​​the glass is defined as s, where S1≤s≤1.2S2. With this layout, the positioning and clamping of multi-specification glass can be satisfied, while also avoiding the bending deformation problem caused by the edge of the largest specification glass extending too far out of the centering platform.

[0022] According to another specific embodiment and preferred aspect of the present invention, the edge grinding equipment further includes a waste recycling unit, which includes a separation box connected to the waste collection section, a sedimentation tank having an inlet and a outlet, and a drain pipe connected to the outlet. The top of the separation box is connected to a negative pressure suction pipe, and the bottom is connected to the inlet. The sedimentation tank has multiple levels of compartments arranged side by side. An overflow gap is formed between each pair of adjacent compartments, and the height of the multiple overflow gaps decreases gradually along the front-back direction. The liquid level in the multiple compartments decreases accordingly. The inlet is connected to the compartment with the highest liquid level, and the outlet is connected to the compartment with the lowest liquid level. Wastewater passes through each level of compartment in sequence, and the volume of the settled debris decreases gradually. Based on multi-stage overflow with progressively decreasing overflow height, this design achieves rapid wastewater overflow under the liquid level difference formed by each stage of the tank, ensuring the fluidity of wastewater between each stage and allowing debris particles of different sizes to settle step by step, effectively improving the uniformity of debris settling. This also effectively increases the probability of uniform changes in the amount of sediment in the multi-stage tank, reduces the cleaning frequency, and helps to reduce labor intensity and improve recycling efficiency.

[0023] Preferably, the sedimentation tank includes a tank body and a plurality of baffles disposed within the tank body and correspondingly distributed between each adjacent compartment, wherein an overflow gap is formed above each baffle, and the height difference between each adjacent overflow gap is progressively reduced along the front-to-back direction.

[0024] Preferably, the multiple partitions are defined as partitions 1, 2...N from front to back. The liquid inlet is located on the front wall of the pool body. The first partition includes a bottom plate located below the liquid inlet and abutting against the front wall of the pool body from one side, and multiple side plates extending upward from the other sides of the bottom plate. The bottom plate, the multiple side plates, and the front wall of the pool body form a trough with the highest liquid level.

[0025] In addition, positioning posts are formed on the front wall of the pool body on both sides opposite to the liquid inlet; the side plates on both sides are bent from one side to form fitting parts that fit the front wall of the pool body, wherein each fitting part has a positioning hole that is inserted into and engaged with the corresponding positioning post; and / or, multiple insertion slots are formed on the left and right side walls of the pool body, which are spaced apart front to back and extend vertically, and the second to N partitions are inserted into the corresponding insertion slots from the left and right sides respectively, and the second to N partitions abut against the bottom of the pool body from the bottom; and / or, multiple filter holes are formed on the first, second...N partitions respectively, wherein the multiple filter holes are set near the top of the corresponding partition.

[0026] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0027] The existing technology uses a linear water jet, which only forms a grinding section between the grinding groove and the glass contact area during the grinding process. Therefore, the water jet can only reach the surface of the grinding wheel and cannot enter the grinding section. Simultaneously, the water jet intercepts some grinding waste, splashing it into the grinding shell, while the remainder is thrown towards the negative pressure port for extraction. Thus, not only is it impossible to achieve synchronous grinding of the glass edge in the flowing water within the grinding section, but the water flow cannot carry the grinding waste towards the negative pressure port, and a large amount of waste residue remains on the inner wall of the grinding shell. If the material lands on the grinding wheel, it will affect the grinding quality, and it also requires frequent disassembly and cleaning, which is time-consuming and labor-intensive. The air knife used is also linear, and its main function is to form another isolation wall to prevent water and debris from splashing and damaging the glass surface. However, the isolation range is limited (water and debris can still splash out in the linear direction formed by the air knife). In addition, most display glass is rectangular, while conventional grinding only grinds one side or corner of the glass. This is not only cumbersome and inefficient, but also causes damage to the glass during grinding. Unilateral force application can easily lead to uneven stress, causing glass deformation or damage. This application addresses this issue by providing a holistic structural design for the edge grinding equipment of display glass, cleverly resolving the shortcomings and defects of existing technologies. With this equipment, the glass is positioned on a positioning platform, and the two grinding units are adjusted relative to each other along the width of the grinding path, aligning the edge or corner to be ground with the grinding units on both sides. The positioning platform is driven by a lateral movement unit to move laterally along the grinding path, and as the glass is inserted into the glass inlet, the glass is pressed against the edge or corner to be ground. The grinding groove is used to form a grinding section with a first end and a second end. An arc-shaped blocking area is formed with the center of the grinding wheel as a reference to block the grinding section by an air knife. A first fluid and a second fluid are formed by a water jet. The first fluid is thrown from the inside of the first end, adhering to the grinding groove as a reference, through the grinding section and towards the waste collection part. The second fluid, based on the air knife blocking, is thrown from the outside of the first end, scouring the glass surface as the grinding wheel rotates, and the waste generated by the scouring is thrown towards the waste collection part. The grinding of the glass edges and corners and the efficient collection of the grinding waste are completed simultaneously. Therefore, compared with the prior art, the present invention, on the one hand, uses the arc-shaped barrier zone formed by the air knife to block the grinding section, and the water jet forms the first and second fluids that pass through the grinding section and respectively adhere to the grinding groove of the grinding wheel and the glass surface to throw the waste to the waste collection part, effectively reducing the probability of waste splashing and residue, improving the grinding quality, and improving the waste collection rate, reducing accumulation, and significantly reducing the cleaning frequency; on the other hand, based on the cooperation of the grinding units on both sides, grinding is carried out synchronously during the lateral movement of the positioning platform and the lateral forces formed by them cancel each other out, effectively improving the stress distribution of the glass and reducing the probability of glass deformation and damage. In addition, it can carry out bilateral or diagonal synchronous grinding simultaneously, effectively improving grinding efficiency. Attached Figure Description

[0054] like Figures 1 to 15 As shown, the screen glass edge grinding equipment of this embodiment includes a positioning platform ①, a lateral movement unit ② that drives the positioning platform ① to move laterally along the grinding path, a grinding unit ③ located on both sides of the grinding path, a centering unit ④, and a waste recycling unit ⑤.

[0055] Specifically, in this embodiment, the display glass B is a rectangular glass, and the positioning platform ① adopts a rectangular suction cup. The display glass B can be adsorbed and positioned on the suction cup and protrude outward from all sides.

[0056] In this example, the transverse unit ② includes a transverse moving force unit Q1 that drives the positioning platform ① to reciprocate along the grinding path, and a rotary force unit Q2 that drives the positioning platform ① to rotate around the vertical centerline to switch the edge or corner of the display glass to be ground. Both the transverse moving force unit Q1 and the rotary force unit Q2 are existing technologies and will not be described in detail here. Grinding is completed by the transverse moving force unit, and the rotary force unit is used to switch the side or corner of the glass to be ground to align with the grinding unit.

[0057] Meanwhile, the transverse unit ② also includes an adjustment power unit Q3 that drives the two grinding units ③ to move relative to each other along the width of the grinding path. The adjustment power unit Q3 uses a power screw to drive the two grinding units to move synchronously towards or away from each other to match the position of the glass edge or corner to be ground of any specification. Based on the synchronicity of movement, the lateral forces generated by the two grinding units ③ grinding the edges or corners on opposite sides of the glass cancel each other out.

[0058] In this example, the grinding unit ③ includes a grinding base 1 and a grinding wheel 2. The grinding base 1 has a glass inlet k0, an air knife f, a water knife s, and a waste collection section g. The grinding wheel 2 has a grinding groove 20 formed from the circumference. The air knife f forms an arc-shaped blocking area q0 with the center of the grinding wheel 1 as a reference. The display glass B is inserted into the glass inlet k0 and abuts against the grinding groove 20 from the edge or corner to be ground to form a grinding section d located in the blocking area q0 and having a first end and a second end. The waste collection section g is aligned with the second end. The outlet of the water knife s is located in the blocking area q0 and aligned with the first end. The water knife s forms a first fluid and a second fluid. The first fluid is thrown from the inside of the first end, adhering to the grinding groove 20 as a reference, through the grinding section d, and towards the waste collection section g. The second fluid, based on the blocking of the air knife f, is swept from the outside of the first end, washing the edges of the front and back of the glass as the grinding wheel 2 rotates. The waste formed by the washing is thrown towards the waste collection section g.

[0059] For ease of implementation, a grinding chamber q1 is formed inside the grinding base 1, and the grinding wheel 2 is inserted into the grinding chamber q1 from top to bottom; the glass inlet k0 is connected to one side of the grinding chamber q1 and is arranged to pass through along the grinding path, wherein the grinding part of the grinding wheel 2 intersects with the inner side of the glass inlet k0 to form a grinding area, and the display glass B moves laterally along the grinding path while keeping the edge or corner to be ground passing through the grinding area.

[0060] In some specific embodiments, the grinding seat 1 includes a first seat body 11 and a second seat body 12 that form a grinding cavity. The first seat body 11 includes an upper part 111 and a lower part 112 arranged vertically. A reflux chamber c0 that communicates with the second end is formed between the upper part 111 and the second seat body 12. The lower part 112 forms a slow flow chamber c1 that communicates with the bottom of the reflux chamber c1.

[0061] In this example, the air knife f includes an upper air knife f0 and a lower air knife f1, which are located on the outside of the second base 12 and form a glass inlet k0 at an interval. A clearance notch k1 is formed on the second base 12 to avoid the grinding wheel 2. The collection ports of the water knife s and the waste collection unit g are located on the second base 12 and on opposite sides of the clearance notch k1 along the grinding path. The collection port of the waste collection unit g is connected to the return chamber c0 and the slow-flow chamber c1. With this arrangement, the fluid ejected by the water knife flows rapidly to the waste collection unit for collection due to its own inertia, the rotation of the grinding wheel, and the transport of the glass, significantly reducing the probability of waste remaining in the grinding area.

[0062] In some specific embodiments, the upper air blade f0 and the lower air blade f1 each form an air inlet cavity a1, an airflow channel a2, and an air outlet a3 connected sequentially from the inside out. The upper and lower airflow channels a2 extend obliquely upwards and downwards and gradually narrow towards the air outlet a3. The upper and lower air outlets a3 respectively include a first arc-shaped segment a31 corresponding to the bottom surface of the upper air blade f0 and the top surface of the lower air blade f1, and two second arc-shaped segments a32 corresponding to the inner surfaces of the upper air blade f0 and the lower air blade f1 and located on opposite sides of the grinding area. The two second arc-shaped segments a32 are connected to the two ends of the first arc-shaped segment a31. The airflow blown by the upper and lower first and second arc-shaped segments cooperates to form a barrier zone q0 covering the grinding area. A drain channel t extending vertically and connected to the clearance notch k1 is formed between the lower air blade f1 and the second base 12. Here, residual waste on the lower surface of the glass is discharged through the drain channel to avoid the accumulation of residue from blocking the movement or grinding of the glass.

[0063] Furthermore, when the glass is inserted into the glass inlet, in the orthographic projection on the horizontal plane, the two ends of the upper air knife f0 and the lower air knife f1 intersect with the two sides of the edge or corner to be ground of the display glass B, respectively. The center lines of the air outlets a3 of the upper air knife f0 and the lower air knife f1 and the grinding wheel 2 coincide, and the space between the upper air knife f0, the lower air knife f1 and the grinding wheel 2 gradually narrows from both ends to the middle. Here, not only can the area of ​​the grinding section be reduced, enhancing the ability to gather and collect waste, but also the glass edge can form a section to be ground and a section already ground outside the barrier zone during grinding. Before and after grinding, the airflow blown out from the upper and lower air outlets of the edge to be ground can converge to quickly isolate the waste to prevent it from escaping, reducing interference with the section to be ground and the section already ground.

[0064] In this example, the second base 12 has a water flow channel communicating with the water jet s and has an outlet 120 located within the obstruction zone q0, and a guide section 121 extending from the outside of the outlet 120 toward the grinding section d (or grinding area). The contact position of the fluid ejected from the outlet 120 on the grinding wheel 2 is located on the side of the first end away from the second end. A guide zone that gradually narrows toward the grinding section d (or grinding area) is formed between the guide section 121 and the grinding wheel 2, and the fluid ejected from the water jet s flows along the guide zone toward the first end. Here, it is convenient for the fluid to converge after being ejected, so as to enhance the scouring effect on the grinding section; at the same time, it enables pre-cooling and cooling of the grinding wheel before and during grinding, ensuring the stability of the grinding temperature and improving the grinding effect.

[0065] In some specific embodiments, the center of the water outlet 120 is flush with the center of the grinding section d, and the diameter of the water outlet 120 is greater than or equal to the thickness of the display glass B. During grinding, the fluid rushing out of the water outlet 120 enters the grinding section d and splits into a first fluid and a second fluid. The waste generated during grinding is collected towards the second end based on the coordinated movement of the first and second fluids, the glass, and the grinding wheel. Here, the grinding wheel is kept immersed in water during grinding, which improves the cooling effect on the grinding wheel. At the same time, based on the coordinated movement of the fluid, the grinding wheel, and the glass, the efficiency of flushing the waste generated during grinding towards the waste collection section is improved.

[0066] In this example, the waste collection section g includes a main collection branch pipe g0 connected to the return chamber c0 and an auxiliary collection branch pipe g1 connected to the slow-flow chamber c1. The main collection branch pipe g0 and the auxiliary collection branch pipe g1 can respectively create negative pressure in the return chamber c0 and the slow-flow chamber c1. The waste generated during grinding enters the return chamber c0 from the second end, and part of the waste is collected through the main collection branch pipe g0, while the other part is collected downwards through the auxiliary collection branch pipe g1. Here, based on the cooperation of the main and auxiliary collection branch pipes, the waste rushing out from the second end is diverted and collected smoothly, further reducing the splashing and accumulation of waste impacting the inner wall of the grinding chamber.

[0067] In some specific embodiments, the reflux chamber c0 is located close to the grinding wheel 2, and has a reflux port k2 on one side that matches the outer contour of the part of the grinding wheel 2 near the second end, and a main collection hole k3 on the opposite side that communicates with the main collection branch pipe g0. Inside the reflux chamber c0, there is a first guide channel c01 extending from the reflux port k2 along the direction of the fluid flowing out from the second end, and a second guide channel c02 extending from the end of the first guide channel c01 away from the second end around the center of the grinding wheel 2. The bottoms of both ends of the second guide channel c02 respectively form auxiliary collection holes k4 that communicate with the slow-flow chamber c1. Here, based on the air knife barrier, the waste material, after being ejected from the second end, undergoes centrifugal motion and enters the reflux chamber, flowing along the inner wall of the reflux chamber. This reduces the splashing phenomenon caused by impacting the inner wall of the reflux chamber, achieving stable collection of waste material and preventing it from remaining on the inner wall of the reflux chamber.

[0068] The height of the main collection hole k3 is lower than that of the grinding section d. Therefore, considering the influence of waste gravity, a high-low drop layout is adopted to increase the probability of waste being discharged through the self-collecting pipe.

[0069] Meanwhile, the two ends of the second guide channel c02 are respectively formed with arc-shaped inner walls extending around the center line of the corresponding auxiliary collection hole k4; the bottom of the slow flow chamber c1 extends vertically and vertically, wherein the connection point of the auxiliary collection branch pipe g1 on the slow flow chamber c1 is close to the lower edge of the bottom of the chamber, the grinding area is located above the upper edge of the bottom of the chamber, and the lower end of the discharge channel t is connected to the slow flow chamber c1; the bottom of the slow flow chamber c1 is also formed with a slow flow groove c10 that is connected one by one with the inlet of multiple auxiliary collection branch pipes g1.

[0070] To further facilitate implementation, a notch k5 is also formed on the second body 12, extending along the grinding path and communicating with the avoidance notch k1. The upper and lower edges of the notch k5 are located above and below the glass inlet k0, respectively. During grinding, as the glass is transported and passes through the grinding section, the upper and lower air knives blow the waste material remaining on the glass surface toward the inside of the notch k5, further reducing the probability of waste material remaining on the glass surface.

[0071] Furthermore, the grinding wheel 2 in this embodiment has multiple grinding grooves 20 of various specifications distributed along its own axial direction. According to process requirements, the grinding wheel 2 is adjusted up and down by a driver connected above it to align the corresponding grinding grooves with the glass inlet k0. The bottom of the first seat 11 has a through hole that matches the grinding wheel 2, allowing residual liquid on the grinding wheel 2 to be collected downwards. This facilitates the downward discharge of excess waste (including wastewater and waste material) below the glass, preventing residual accumulation from obstructing the movement or grinding of the glass.

[0072] In this example, the centering unit ④ includes a centering platform 3, a centering actuator 4, and a transfer robot 5. The glass is placed flat on the upper surface of the centering platform 3. Multiple clearance grooves 30 are formed on the centering platform 3 around the glass. Each clearance groove 30 extends from the outside to the inside and its inner end is located directly below the glass. Each clearance groove 30 penetrates the centering platform 3 in the vertical direction.

[0073] For ease of implementation, the centering platform 3 is rectangular, with three parallel and spaced clearance grooves 30 on each side. Each clearance groove 30 extends inward from the corresponding side of the centering platform 3, and the inner ends of the three clearance grooves 30 on the same side are flush. Here, the clearance grooves are connected to the outside of the centering platform to facilitate continuous alignment and clamping of large-area glass (glass surface area greater than the surface area of ​​the centering platform) and small-area glass (glass surface area less than the surface area of ​​the centering platform).

[0074] Meanwhile, the extension direction of each clearance groove 30 is perpendicular to the extension direction of the corresponding glass side; and when clamped and positioned, each side of the glass is parallel to the corresponding side of the centering platform 3.

[0075] In some specific embodiments, the upper surface of the centering platform 3 is divided into a first region m1 located between the inner ends of multiple clearance grooves 30 and a second region m2 located around the first region m1. In other words, the inner ends of the multiple clearance grooves 30 surround the first region m1, and the edge of the centering platform 3 forms the second region m2 between the inner ends of the multiple clearance grooves 30. During material placement, the glass is placed from the center into the first region m1, extends into the second region m2 from the side, or protrudes out of the second region m2. In the orthographic projection on the horizontal plane, the area of ​​the first region m1 is S1, the area of ​​the centering platform 3 is S2, and the area of ​​the glass is defined as s, where S1 < S2, S1 ≤ s ≤ 1.2S2. With this layout, the positioning and clamping of multi-specification glass can be satisfied, while also avoiding the bending deformation problem caused by the edge of the largest specification glass extending too far out of the centering platform.

[0076] In this example, the centering actuator 4 includes multiple push rods 40 corresponding to multiple clearance slots 30, and a power component 41 that drives each push rod 40 to reciprocate along the corresponding clearance slot 30. Each push rod 40 on each side forms a line contact with the corresponding side of the glass. The multiple push rods 40 retract inward along the clearance slot 30 with the center line of the centering platform 3 as a reference and clamp the glass around its perimeter. The center line of the glass then coincides with the center line of the centering platform 3.

[0077] To further facilitate implementation, each push rod 40 is cylindrical, and when clamped, the sidewall of the cylinder forms line contact with the edge of the glass; push rods 40 on any two opposite sides are aligned one-to-one. Each push rod 40 includes a rod body 400 and a pusher section 401 that rotates freely around a vertical center line and is connected to the upper end of the rod body 400, wherein the pusher section 401 extends from bottom to top through a corresponding clearance groove 30. The power component 41 adopts a conventional power screw drive component, which will not be described in detail here.

[0078] In addition, the transfer robot 5 includes a transfer suction cup 50 based on a multi-head array layout and a transfer power component 51 that drives the transfer suction cup 50 and forms a transfer path perpendicular to the grinding path. After the glass is aligned, the transfer suction cup 50 picks up the glass from the alignment platform and transfers it to the positioning platform based on the drive of the transfer power component 51.

[0079] In this example, the waste recycling unit ⑤ includes a separation box 6 connected to the waste collection section g, a sedimentation tank 7, a drainage pipeline 8, and a wastewater recycling station.

[0080] Specifically, the top of the separation box 6 has a negative pressure interface 60 that connects to the negative pressure suction pipe (not shown in the figure, but easy to imagine), and the bottom is connected to the sedimentation tank 7 through a pipe (not shown in the figure, but easy to imagine). The main collection branch pipe g0 and the auxiliary collection branch pipe g1 are respectively connected to one side of the separation box 6 from the outlet. Therefore, during the collection process, wastewater and large particles of waste fall into the bottom of the separation box 6, and the floating fine particles of dust are extracted from the top negative pressure interface 60. The sedimentation tank 7 has an inlet k6, a outlet k7, and an overflow outlet k8 located above the outlet k7. The sedimentation tank 7 has multiple levels of compartments arranged side by side from front to back, and an overflow gap k9 is formed between each pair of adjacent compartments. The height of the multiple overflow gaps k9 is gradually reduced along the front-back direction, and the liquid level in the multiple compartments is gradually reduced accordingly. The inlet k6 is connected to the compartment with the highest liquid level (i.e., the compartment at the front); the outlet k7 and the overflow outlet k8 are connected to the compartment with the lowest liquid level (i.e., the compartment at the back). Wastewater passes through each level of compartment in sequence, and the volume of the sedimented debris decreases at each level. It should be noted that in this embodiment, the drainage rate of the drain outlet k7 is greater than or equal to the drainage rate of the inlet k6 to avoid the wastewater level in the last compartment rising. Based on the potential energy difference of the wastewater generated by the liquid level difference between each compartment, the flow of the wastewater is accelerated. Combined with the different sedimentation rates of glass fragments of different volumes (which can also be understood as different masses) (the larger the volume, the faster the sedimentation rate), the compartments are divided into each level and the volume of the settled glass fragments decreases step by step.

[0081] For ease of implementation, the sedimentation tank 7 includes a rectangular tank body 70, multiple baffles 71 disposed within the tank body 70 and correspondingly distributed between each adjacent compartment, and a top cover 72 covering the tank body 70. Each baffle 71 has an overflow notch k9 formed above it. In this embodiment, the compartments are arranged in four stages. Practical experience has shown that the first three stages are sufficient to achieve sedimentation and filtration of all glass fragments, and the wastewater entering the last stage is already clear water for direct discharge. Therefore, three baffles 71 are correspondingly provided, and these three baffles 71 are defined from front to back as the first baffle, the second baffle, and the third baffle. The height difference between each adjacent overflow notch k9 decreases progressively along the front-to-back direction.

[0082] In some specific embodiments, the inlet k6 is located on the front wall of the tank body 70. The first partition includes a bottom plate located below the inlet k6 and abutting against the front wall of the tank body 70 from one side, and multiple side plates extending upward from the other sides of the bottom plate. The bottom plate, the multiple side plates, and the front wall of the tank body 70 together form a trough with the highest liquid level. This facilitates the interception and collection of larger glass fragments in the wastewater.

[0083] In this example, two sets of insertion slots are formed on the left and right side walls of the pool body 70, which are spaced apart and extend vertically. The second and third partitions are both straight plates and are inserted into the corresponding insertion slots from the left and right sides respectively. The second and third partitions abut against the bottom of the pool body 70 from the bottom.

[0084] To further facilitate implementation, multiple filter holes are formed on the first, second, and third partitions, with the filter holes arranged in a rectangular array near the top of the corresponding partition. This facilitates the interception and collection of floating debris above the liquid surface in each compartment.

[0085] Specifically, the pore size of the filter on the first partition is larger than that on the second and third partitions. Here, the foremost compartment filters only large glass fragments for rapid collection.

[0086] Furthermore, the drain outlet k7 is located near the bottom of the sedimentation tank 7, and the overflow outlet k8 is located directly above the drain outlet k7. The drain pipe 8 includes a drain pipe 80 connected to the drain outlet k2 and an overflow pipe 81 connected to the overflow outlet k8. A control valve is installed on the drain pipe 80. The height of the overflow outlet k8 is higher than the height of the third baffle. The discharged wastewater is discharged through the drain pipe 80 and collected in the wastewater recycling station. Here, the cooperation of the drain pipe and the overflow pipe prevents the liquid level in the entire sedimentation tank from accidentally becoming too high.

[0087] In summary, by adopting this edge and corner grinding equipment, the glass is positioned on the positioning platform, and the two grinding units are adjusted relative to each other along the width of the grinding path so that the edge or corner of the glass to be ground is aligned with the grinding units on both sides of the grinding path. The positioning platform is driven to move laterally along the grinding path by the lateral unit, and as the glass is inserted into the glass inlet, the glass abuts against the grinding groove from the edge or corner to be ground to form a grinding section with a first end and a second end. An arc-shaped blocking area is formed by the air knife with the center of the grinding wheel as the reference to block the grinding section. A first fluid and a second fluid are formed by the water jet. The first fluid is thrown from the inside of the first end, adhering to the grinding groove with the grinding groove as the reference, through the grinding section and towards the waste collection section. The second fluid, based on the air knife blocking, is swept from the outside of the first end as the grinding wheel rotates and washes the glass surface, and the waste formed by the washing is thrown towards the waste collection section. The grinding of the glass edge and corner and the efficient collection of the grinding waste are completed simultaneously.Therefore, compared with the prior art, this invention, on the one hand, uses the arc-shaped obstruction zone formed by the air knife to block the grinding section, and uses water jets to form first and second fluids that pass through the grinding section and respectively adhere to the grinding groove of the grinding wheel and the glass surface to throw the waste material to the waste collection section, effectively reducing the probability of waste splashing and residue, improving grinding quality, and increasing the waste collection rate, reducing accumulation, and significantly reducing the cleaning frequency; on the other hand, based on the cooperation of the grinding units on both sides, grinding is carried out synchronously during the lateral movement of the positioning platform, and the lateral forces formed by them cancel each other out, effectively improving the stress distribution of the glass and reducing the probability of glass deformation and damage. In addition, it can simultaneously carry out bilateral or diagonal synchronous grinding, effectively improving grinding efficiency; thirdly, it can not only reduce the area of ​​the grinding section, but also increase the efficiency of grinding. The system possesses strong waste collection and aggregation capabilities. Simultaneously, during grinding, the glass edge forms a section to be ground and a ground section outside the closed grinding section. Before and after grinding, the airflow from the upper and lower air outlets protruding from the edge to be ground quickly isolates the waste to prevent escape, reducing interference with the ground and ground sections. Fourthly, by setting up drainage channels, excess waste (including wastewater and waste material) below the glass is easily discharged downwards, preventing residual accumulation from obstructing the glass's movement or grinding. Fifthly, maintaining the grinding wheel immersed in water during grinding enhances the cooling effect on the grinding wheel. Furthermore, based on the coordinated movement of the fluid, grinding wheel, and glass, the efficiency of flushing grinding waste to the waste collection section is improved. Sixthly... The fluid, after being ejected from the water jet outlet, converges to enhance the scouring effect on the grinding section. Simultaneously, it pre-cools and cools the grinding wheel before and during grinding, ensuring stable grinding temperature and improving grinding performance. Seventhly, based on the air knife's obstruction, waste material ejected from the second end undergoes centrifugal motion and enters the return chamber, flowing along its inner wall. This reduces splashing caused by impacts on the return chamber wall, achieving stable waste collection and preventing residue on the return chamber wall. Eighthly, negative pressure is created in the main and auxiliary collection branches to ensure complete collection of fine dust and droplets generated during grinding. Ninthly, a slow-flow trough design allows waste material to converge and discharge within the trough, preventing insufficient fluidity due to low liquid content. This leads to the problem of solids not being able to be discharged; tenthly, it meets the needs of center positioning and clamping of multi-specification glass plates, making it highly practical; at the same time, it can effectively reduce the resistance generated by the glass being picked up under clamping, significantly reduce the probability of glass deformation, and improve the picking accuracy, so that the glass can be transferred to the positioning platform for precise grinding of the sides and corners; eleventhly, based on multi-stage overflow with progressively decreasing overflow height, it achieves rapid overflow of wastewater under the liquid level difference formed by each stage of the tank, ensuring the fluidity of wastewater between each stage of the tank, and gradually settling debris particles of different volumes, effectively improving the uniform settling of debris; it effectively increases the probability of uniform change in the amount of sediment in the multi-stage tank, reduces the cleaning frequency, and helps to reduce labor intensity and improve recycling efficiency.
