[0002] In the manufacturing and deep processing of modern glass products, in order to ensure the safety, processability and aesthetics of glass in subsequent secondary processing links such as tempering, laminating, and insulating, glass edge grinding has become an essential pretreatment process. The existing glass grinding equipment mainly adopts two structures: sand belt type and grinding wheel type. Among them, the grinding wheel type is widely used in straight edge grinding operations due to its high grinding accuracy and stable efficiency. However, traditional grinding wheel type glass grinding equipment is mostly horizontal devices, which have problems such as large equipment volume, obvious limitations in layout methods, and inability to directly connect and dock with the current mainstream vertical insulating glass production line. As a result, auxiliary equipment such as horizontal turning tables and manual handling platforms need to be additionally set up in the production process, which not only increases the floor area and system complexity, but also improves the manual participation and handling risks.

[0019] To make the objectives, technical solutions, and advantages of this application clearer and more understandable, the following further elaborates on this application in detail with reference to specific embodiments and the accompanying drawings.

[0020] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the embodiments of this application should have the ordinary meanings understood by those with ordinary skills in the field to which this application belongs. The "first", "second", and similar terms used in the embodiments of this application do not denote any order, quantity, or importance, but are only used to distinguish different components. Words such as "including" or "comprising" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. Words such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0021] As described in the background art, in the modern glass manufacturing and processing industry, raw glass usually needs to undergo a series of pretreatment operations after cutting to meet the process requirements and safety specifications of subsequent processes such as tempering, laminating, and insulating glass assembly. Among them, glass edge grinding is a crucial processing step, the purpose of which is to remove burrs and sharp edges after glass cutting, improve the edge quality, reduce the risk of breakage, prevent personnel from being scratched, and achieve a double improvement in dimensional accuracy and visual aesthetics. Therefore, almost all glass must undergo edge grinding before becoming a finished product or entering the deep processing process.

[0022] To solve the above problems, currently in the industry, a glass edge grinding method mainly based on mechanical grinding is often used to grind the glass workpiece 1, which mainly includes two structures: sandbelt type or grinding wheel type. Among them, the grinding wheel type glass grinding equipment has become the mainstream technical means for straight glass edge grinding due to its advantages such as high processing efficiency, good grinding accuracy, and strong processing consistency. Refer to Figure 1 , the existing grinding wheel type glass grinding equipment includes a flat grinding wheel 2 and a connecting rod 3, which are rotatably connected through a knuckle joint 4 to facilitate adjusting the grinding position. During the actual working process, the grinding wheel type edge grinding equipment contacts the edge of the glass workpiece 1 through the high-speed rotating flat grinding wheel 2 to achieve continuous and efficient grinding processing, which is suitable for large-scale and standardized industrial application scenarios.

[0023] However, the applicant has found that although the introduction of a grinding wheel type glass grinding equipment into the glass edge grinding process production operation solves the problem that glass must be edge ground before becoming a finished product or entering the deep processing process, most of the existing grinding wheel type glass grinding equipment is of a horizontal structure, that is, the glass is conveyed to the grinding area in a horizontal state. This layout has some problems. First, since the glass must be transmitted in a horizontally flattened state during processing, it brings a large horizontal floor space for equipment layout, and at the same time restricts the compactness and layout flexibility of the overall production line; the whole set of equipment is bulky, which is not conducive to the improvement of the factory space utilization rate. Secondly, since the current mainstream insulating glass production line generally adopts a vertical layout, the traditional horizontal edge grinding equipment cannot be directly connected in series with it. Therefore, after the horizontal edge grinding is completed, it is necessary to manually carry or additionally set up a flipping device to convert the glass from a horizontal state to a vertical state, which not only greatly increases the system complexity and operation cost of the production line, but also prolongs the processing cycle, increases the frequency of manual intervention and potential handling safety hazards, seriously restricting the improvement of the overall automation efficiency.

[0024] In addition, from the perspective of the contact structure between the flat grinding wheel 2 and the glass workpiece 1, in the horizontal equipment, a grinding method is often used in which the working plane of the flat grinding wheel directly makes line contact with the glass edge. As the grinding wheel runs for a long time, the working surface thereof is prone to non-uniform wear, resulting in deformation of the contact surface, thereby gradually decreasing the edge grinding accuracy and deteriorating the grinding consistency, which not only affects the product quality, but also shortens the service life of the grinding wheel, increases the maintenance frequency and operation cost.

[0025] In view of the problems of the above-mentioned glass grinding equipment, such as large floor area and inability to directly connect in series with the current mainstream vertical insulating glass production line, the applicant proposes a vertical glass grinding mechanism 010 with a small floor area, strong applicability and capable of efficiently connecting with the vertical automated production line, and introduces the assembly into the vertical glass grinding system. The applicant has found that the equipment layout method of the traditional horizontal structure can be optimized into a vertical structure, so that the glass is conveyed and ground in a vertical state during processing. By means of this vertical layout method, not only the floor space required for the traditional horizontal structure to be laid flat is significantly reduced, but also the edge grinding operation can be directly embedded in the vertical insulating glass production line, eliminating links such as glass flipping and intermediate handling, so as to realize efficient in-line connection with the mainstream vertical production line, effectively simplify the production process, and improve the overall automation level and production efficiency.

[0026] In addition, the grinding method in which the working plane of the flat grinding wheel commonly used in horizontal equipment is directly in line contact with the edge of the glass can be changed to form a grinding angle a between the first grinding wheel 101a and the second grinding wheel 101b arranged close to each other, and use the grinding angle a to contact the edge to be ground of the glass workpiece 1 to be processed for edge grinding operation. Through double-wheel angle grinding, not only can the problems of uneven wear and deformation of the grinding wheel caused by single-sided grinding be avoided, the edge grinding accuracy and consistency can be improved, but also the grinding angle can be adjusted in combination with the driving component or the relative distance from the glass workpiece 1 can be adjusted to achieve adaptive processing of glass of different specifications, thereby effectively improving the grinding efficiency and extending the service life of the grinding wheel.

[0027] The following will Figure 2 - 22 describe the embodiments of the present application in detail with reference to the accompanying

[0028] In some embodiments, as Figure 2 shown in Figure 3 、 Figure 21 and Figure 22 , a vertical glass grinding mechanism 010 includes: A connecting arm group 100, including a first connecting arm 100a and a second connecting arm 100b driven by a driving member 110 to move; A grinding wheel group 101, including a first grinding wheel 101a and a second grinding wheel 101b arranged close to each other, the first grinding wheel 101a and the second grinding wheel 101b are respectively rotatably connected to the first connecting arm 100a and the second connecting arm 100b; the first grinding wheel 101a and the second grinding wheel 101b are arranged in a staggered manner in a first direction, and their orthographic projections in the first direction are tangent or partially overlapped, and a grinding angle a is formed between the tangent or overlapping regions to grind the edge to be processed of the glass workpiece 1; Wherein, driven by the driving member 110, the first connecting arm 100a and the second connecting arm 100b move relatively to change the position or angle of the grinding angle a; the first direction is the axial direction of the first grinding wheel 101a or the second grinding wheel 101b.

[0029] Exemplarily, the connecting arm group 100 includes a first connecting arm 100a and a second connecting arm 100b, which are driven by their respective driving members 110 (such as servo electric cylinders, electric push rods or feed cylinders) to achieve relative movement adjustment. The end of each connecting arm bears a grinding wheel respectively, and the relative distance and angle between the two grinding wheels are adjusted by the driving member 110. In addition, in order to ensure the synchronism and angle adjustment accuracy of the movement of the first connecting arm 100a and the second connecting arm 100b, auxiliary mechanisms such as articulated connecting rods or parallel guide rails can be adopted in the structure to make the two connecting arms move stably under the action of the driving member 110.

[0030] Exemplarily, the grinding wheel set 101 is composed of a first grinding wheel 101a and a second grinding wheel 101b. The two wheels are arranged opposite to each other and are staggeredly arranged in the first direction (such as the x direction in Figure 2 ). Specifically, each grinding wheel is connected to the end of the corresponding connecting arm through a bearing seat and a rotating shaft, and is driven to rotate by an independent grinding wheel motor 103. In addition, due to the staggered arrangement in the first direction, the two grinding wheels form a "V-shaped" included angle area in space, and this "V-shaped" intersection area is exactly the working channel where the glass workpiece 1 contacts the grinding wheel for edge grinding. This included angle can be adjusted by the driving member 110, and has high adaptability when dealing with different glass edge thicknesses, edge types or chamfering processes.

[0031] Exemplarily, there are multiple driving members 110. To achieve flexible adjustment of the grinding angle and spatial position, a multi-directional arrangement can be adopted. They can be respectively arranged above, below or on both sides of the first direction of the first connecting arm 100a and the second connecting arm 100b, and combined control can be carried out according to actual process requirements. Among them, the driving members 110 arranged on both sides are mainly responsible for adjusting the relative position between the grinding wheels. Through synchronous driving, the grinding wheels can be moved closer to or away from the glass workpiece 1 as a whole, and through differential driving, the included angle between the two grinding wheels on both sides can be changed, so as to flexibly adjust the size of the grinding angle to meet the requirements of different edge types or processing precisions; while the driving members 110 arranged above and below in the first direction can be used to adjust the axial height position of the grinding wheels.

[0032] Through the combined adjustment mechanism of multi-directional driving in the up, down, left and right directions, not only can the grinding wheels move closer to each other or away from each other to change the included angle of the grinding angle a, but also the depth of the "V-shaped" grinding area of the grinding angle a along the first direction can be increased or decreased. This multi-driving layout structure has higher adjustment freedom and control precision, enabling the vertical glass grinding mechanism 010 to flexibly adapt to various chamfering angles, edge profiles or glass thickness differences.

[0033] Exemplarily, to ensure the grinding effect and equipment stability, the first grinding wheel 101a and the second grinding wheel 101b can adopt resin or ceramic bonded diamond wheels to meet the requirements of high-strength and high-precision grinding; the rotating shaft can adopt a sealed corrosion-resistant bearing to prevent coolant from seeping in; the connecting arm can be made of aluminum alloy profiles or high-strength welded structures, taking into account both light weight and rigidity.

[0034] At the same time, this equipment can also be configured with a limit device to prevent interference or damage caused by the structure over-traveling. Cooperating with the automatic spray cooling system, it can cool down in real time to prevent thermal explosion, extend the service life of the grinding wheel, and improve the overall processing quality and equipment durability.

[0035] Combined with the edge grinding process of the starting edge 11 of the glass workpiece 1, the present embodiment is described as follows: During the actual grinding process, the glass workpiece 1 is fed in the conveying direction and temporarily stops after running to the preset position. At this time, the grinding wheel set 101 moves towards the glass workpiece 1 under the drive of the driving member 110 until the "V-shaped" grinding included angle area formed by the grinding angle a is in contact with the two edges of the to-be-processed edge of the glass workpiece 1 at the same time. After positioning, the vertical glass grinding mechanism 010 moves up and down under the drive of the lifting mechanism to realize synchronous grinding of the glass edge and form a double-sided edge grinding effect.

[0036] Compared with the processing method in the traditional horizontal grinding structure where the working plane of the grinding wheel directly contacts the glass edge line, the structure of this embodiment designs the space included angle between the two grinding wheels, so that the two included angle sides of the grinding angle a are in contact with the two edges of the to-be-processed edge of the glass workpiece 1 at the same time. The grinding process is more uniform, and it can effectively avoid problems such as edge warping or non-uniform grinding caused by local load concentration. At the same time, since the grinding force is shared by two directions, the single-point load is significantly reduced, which helps to improve the stability of the processing process and the finished product quality.

[0037] The vertical glass grinding mechanism 010 in this embodiment includes a connecting arm group 100 and a grinding wheel group 101. The connecting arm group 100 includes a first connecting arm 100a and a second connecting arm 100b driven by a driving member 110. The grinding wheel group 101 includes a first grinding wheel 101a and a second grinding wheel 101b arranged close to each other. The two are respectively rotatably connected to the first connecting arm 100a and the second connecting arm 100b, and are arranged in a staggered manner in the first direction (i.e., the axial direction of the first grinding wheel 101a or the second grinding wheel 101b), so that their orthographic projections are tangent or partially overlapped, and a grinding angle a is formed between the tangent or overlapping areas; by driving the connecting arm to move relatively by the driving member 110, the position or angle of the grinding angle a can be flexibly adjusted, so as to realize efficient grinding of the to-be-processed edge of the glass workpiece 1. The vertical glass grinding mechanism 010 in this embodiment changes the structural setting in the horizontal equipment where the working surface of the flat grinding wheel contacts the glass edge line. Instead, an included angle area is constructed between the first grinding wheel 101a and the second grinding wheel 101b to contact and grind the two edges of the to-be-processed edge of the glass workpiece 1, which not only avoids the problems of uneven wear of the grinding wheel and local deformation of the glass edge caused by single-sided line contact, but also improves the stability and uniformity of the grinding process. At the same time, the driving component can adjust the grinding angle and the relative distance from the glass workpiece 1, so that it can flexibly adapt to the edge grinding requirements of different specifications of glass, thereby improving the grinding efficiency, processing accuracy and the service life of the grinding wheel.

[0038] In some embodiments, such as Figure 2 、 Figure 3 and Figure 21As shown, at least one of the first grinding wheel 101a and the second grinding wheel 101b is a double grinding wheel structure; the double grinding wheel structure includes an upper grinding wheel 101d and a lower grinding wheel 101e, which are sleeved on the same rotating shaft and rotatably connected to the end of the first connecting arm 100a or the second connecting arm 100b through the rotating shaft; the upper grinding wheel 101d and the lower grinding wheel 101e are arranged at intervals and together with the rotating shaft enclose an annular groove 101c.

[0039] Exemplarily, the double grinding wheel structure adopts a coaxial installation method, and positioning washers, limit slots or fixed collar rings can be used to ensure the axial spacing and position accuracy of the two grinding wheels. Specifically, one end of the rotating shaft is connected to the first connecting arm 100a or the second connecting arm 100b through a bearing assembly or a coupling, and power is provided by the grinding wheel motor 103 or other rotating drive devices; the upper grinding wheel 101d and the lower grinding wheel 101e are firmly fixed to the rotating shaft through set screws or key grooves respectively, and the spacing between them is slightly larger than the thickness of one grinding wheel.

[0040] Exemplarily, to improve the processing efficiency and the ability of multi-process integration, the double grinding wheel structure can also adopt a combined configuration of different grain sizes. Specifically, the upper grinding wheel 101d is selected with a coarse grain size for rough grinding, and the lower grinding wheel 101e is selected with a fine grain size to complete fine grinding, forming a continuous and efficient grinding path. At the same time, the annular groove 101c area in the "V-shaped" working channel can provide wrapping support for the glass workpiece 1, which not only plays a role in stable support and guidance, but also makes the force path of the glass workpiece 1 more reasonable, reducing the risk of eccentric load and jumping.

[0041] Exemplarily, to ensure long-term stable operation in a high-precision grinding environment, diamond grinding wheels with resin or metal bond can be selected to match different types of glass materials; the rotating shaft should preferably be made of high-strength and corrosion-resistant alloy steel and undergo dynamic balance and anti-rust treatment; the spacing between the upper and lower grinding wheels should be designed to be adjustable, such as by replacing washers or using a threaded fine-tuning structure. In addition, the installation accuracy requirements are high, and the axial runout and radial deviation need to be controlled within 0.01 mm to avoid vibration caused by high-speed rotation. At the same time, a cooling spray system specifically for the annular groove 101c area can be equipped to prevent powder chips from accumulating and heat from concentrating, improving the grinding wheel life and processing quality.

[0042] Exemplarily, when at least one of the first grinding wheel 101a and the second grinding wheel 101b is of a double grinding wheel structure, the other grinding wheel is disposed opposite to the annular groove 101c. At this time, the double grinding wheel structure on one side (composed of the upper grinding wheel 101d and the lower grinding wheel 101e) and the single grinding wheel or the other double grinding wheel on the opposite side are combined to form a structure with at least three wheels arranged in a staggered manner, forming a "shearing beam" - type configuration. These grinding wheels are arranged in a staggered manner in the first direction in space, and their axes do not coincide with each other, enclosing a "V - shaped" grinding intersection area with a longitudinal depth as the working channel for grinding the glass workpiece 1.

[0043] Specifically, taking the example that the edge to be processed of the glass workpiece 1 longitudinally passes through the grinding angle a, in the vertical glass grinding mechanism 010, after the glass workpiece 1 is conveyed to the grinding area, it will successively contact the upper grinding wheel 101d, the opposite - side grinding wheel (i.e., the middle grinding wheel 101f or the upper grinding wheel 101d or the lower grinding wheel 101e in the other double grinding wheel structure), and the lower grinding wheel 101e, constituting a "shearing beam" - type structure formed by at least three wheels arranged in a staggered manner. First, the edge of the glass workpiece 1 enters the area of the upper grinding wheel 101d of the double grinding wheel structure, receiving an initial grinding force from above. At the same time, due to the arrangement direction of the grinding wheels, its edge also receives a certain lateral thrust, pushing the glass workpiece 1 towards the opposite - side grinding wheel; subsequently, the glass workpiece 1 continues to move forward and contacts the opposite - side grinding wheel disposed opposite to the two grinding wheels and facing the annular groove 101c area, generating a transverse grinding force here. The opposite - side grinding wheel also exerts a certain reverse force on the edge of the glass workpiece 1, forming a balance with the lateral force generated by the upper wheel, thereby realizing the lateral stable control of the edge of the glass workpiece 1; finally, the edge of the glass workpiece 1 enters the contact area of the lower grinding wheel 101e, jointly forming a pair of vertical clamping forces with the upper grinding wheel 101d, constructing a complete "upper - side - lower" stable clamping relationship.

[0044] Through this arrangement method of at least three wheels that are vertically staggered and spatially crossed, a force system similar to a shearing beam is formed mechanically, forming a stable support and wrapped grinding path for the glass edge. The grinding load is dispersed and balanced in multiple directions, significantly reducing the risks of warping, jumping, or edge breakage caused by single - sided stress. At the same time, compared with the traditional two - wheel staggering, in the arrangement method of at least three wheels, the contact area of glass grinding is elongated and the contact area is increased, making the grinding path more stable and controllable, contributing to achieving higher - precision and higher - consistency edge processing effects, and is particularly suitable for high - requirement grinding processes of thick glass or special - shaped edges.

[0045] In addition, by separating the first grinding wheel 101a and the second grinding wheel 101b axially, the original dot-shaped or linear "V-shaped" contact area is extended into a grinding channel with a certain length. When the glass workpiece 1 is fed, its edge to be processed will continuously stay in this extended intersection area and successively contact different grinding surfaces of at least three grinding wheels, so as to realize a continuous machining path for rough grinding, fine grinding or multi-angle chamfering. After the intersection area is extended, not only the grinding efficiency is improved, but also the wrapping force and fitting stability of the glass edge are enhanced.

[0046] In this embodiment, through the misaligned layout of at least three grinding wheels, not only a structural mechanics support system similar to a shear beam is constructed, which has excellent rigidity and force path distribution ability; at the same time, through the geometric design of spatial intersection, the effective contact stroke of the glass workpiece 1 in the "V-shaped" grinding area is extended, realizing high-quality and highly consistent edge grinding.

[0047] In some embodiments, as Figure 2 , Figure 3 , Figure 21 and Figure 22 shown, one of the first grinding wheel 101a and the second grinding wheel 101b is a double grinding wheel structure, and the other is a single grinding wheel structure; the single grinding wheel structure includes a middle grinding wheel 101f, the middle grinding wheel 101f is sleeved on a rotating shaft and is rotatably connected to the end of the first connecting arm 100a or the second connecting arm 100b through the rotating shaft; the middle grinding wheel 101f is arranged opposite to the annular groove 101c or at least part of the middle grinding wheel 101f is embedded in the annular groove 101c to form the grinding angle a between the first grinding wheel 101a and the second grinding wheel 101b; or, both the first grinding wheel 101a and the second grinding wheel 101b are double grinding wheel structures, and the upper grinding wheel 101d or the lower grinding wheel 101e of one of the first grinding wheel 101a and the second grinding wheel 101b is arranged opposite to the annular groove 101c of the other grinding wheel or at least part of it is embedded in the annular groove 101c of the other grinding wheel to form the grinding angle a between the first grinding wheel 101a and the second grinding wheel 101b.

[0048] Exemplarily, in the combination mode of "double grinding wheel + single grinding wheel", the middle grinding wheel 101f can be set to contact the groove edge relatively or partially embed into the groove interior according to the processing requirements, so as to form a "V-shaped" grinding intersection area with a longitudinal depth. This design can significantly enhance the grinding fitting degree and is especially suitable for the fine processing of ultra-thin glass or special-shaped edges.

[0049] In the "double grinding wheel + double grinding wheel" mode, double grinding wheel structures are provided on both sides. The upper or lower wheel on one side can be opposite to or embedded and docked with the groove area on the other side, forming a more stable angular relationship in space. This symmetrical design can achieve four-point enclosing grinding, improving the overall clamping rigidity and grinding uniformity.

[0050] Exemplarily, the middle grinding wheel 101f is usually arranged on an independent rotating shaft and is strictly axially and radially aligned with the double wheels on the opposite side. The embedding depth needs to be precisely matched by reasonably designing the groove width and the middle grinding wheel 101f, leaving a gap of about 0.5 - 2 mm to avoid interference or jamming during processing, while maintaining an appropriate degree of freedom for slipping. The distance between the double grinding wheels can be adjusted by a limiting ring or a gasket to achieve a stable fit with the middle grinding wheel 101f.

[0051] Exemplarily, in terms of structural cooperation, the double grinding wheels can provide an enclosing force in the up and down directions, while the middle grinding wheel 101f forms a transverse clamping force or an active cutting force, thus constituting a three-dimensional angular area, enabling the glass edge to be subjected to stable multi-point grinding when passing through. In addition, the structural combination of double grinding wheels against double grinding wheels, through the design of the concave-convex fitting area, can further strengthen the attitude control of the glass edge and maintain a constant fitting pressure during the processing.

[0052] Exemplarily, special attention should be paid to the material and supporting design in this embodiment: the diameter of the middle grinding wheel 101f can be slightly smaller than the groove opening, and the thermal expansion margin should be considered; the grinding wheel is preferably made of a lightweight and high-strength material, such as a diamond layer with an aluminum alloy skeleton combined with a resin or metal binder; the dead corners for powder accumulation should be avoided in the embedding structure area, and an air knife or a spraying and washing mechanism should be provided for cleaning; in order to prevent structural damage caused by accidental collisions, a limiting device and a protective buffer layer should be provided in the embedding area; in addition, a visual recognition system or a displacement sensor can be combined to achieve automatic adjustment of the angle and real-time monitoring of the contact state, further improving the intelligent level of grinding.

[0053] [[ID=I2]]This embodiment provides two structural forms of the first grinding wheel 101a and the second grinding wheel 101b, and both structural forms can stably form a grinding angle a between the grinding wheels, ensuring that the edge of the glass workpiece 1 is always in the angular area for grinding. Whether it is a single wheel against double wheels in an embedded / tangential manner or double wheels in an embedded / tangential manner, efficient and uniform glass contact grinding can be achieved, meeting the processing requirements of glass with different thicknesses and edge types, and effectively improving the grinding quality and equipment adaptability.

[0054] In some embodiments, such as Figure 2 、 Figure 3 and Figure 21As shown, the first connecting arm 100a and the second connecting arm 100b are oppositely arranged along the first direction, and a driving member 110 is provided at one end on the same side of each of them; the driving member 110 includes a feeding cylinder, and each feeding cylinder is vertically fixed to one end of the corresponding connecting arm, so that the feeding cylinder drives the grinding wheel set 101 to approach or move away from the glass workpiece 1.

[0055] Exemplarily, the first connecting arm 100a and the second connecting arm 100b are oppositely arranged along the first direction (i.e., the axial direction of the grinding wheel), the first connecting arm 100a is located above the second connecting arm 100b, which is different from the common horizontal opposite arrangement mode of the two connecting arms in the traditional structure. By changing the relative arrangement of the connecting arms from horizontal to vertical, this method significantly shortens the occupied width of the grinding mechanism in the horizontal direction, makes the overall structure more compact, and effectively saves the horizontal space of the equipment.

[0056] In addition, the opposite arrangement of the two connecting arms in the first direction not only helps to reduce the volume of the equipment, but also enables some driving members 110 to be directly vertically arranged at the ends of the connecting arms, improving the assembly efficiency and structural stability. And in cooperation with the guide rail, the connecting arms can achieve a more stable grinding wheel adjustment movement.

[0057] Exemplarily, in the vertical glass grinding mechanism 010, the first connecting arm 100a and the second connecting arm 100b, as the core structures for carrying the first grinding wheel 101a and the second grinding wheel 101b, are oppositely arranged along the axial direction of the grinding wheel (i.e., the first direction), and constitute the basic grinding framework by arranging face to face.

[0058] The feeding cylinder can be fixed to the main body frame through a flange seat. At the same time, the piston rod end built in the feeding cylinder can be rigidly connected to the arm end of the connecting arm, or the force can be transmitted through a buffer cylinder structure to ensure stable structure and rapid response during vertical movement. At the same time, to ensure the stable and reliable movement direction of the connecting arm, the arm body can be connected to the main body frame by means of a roller guiding device or a high-precision linear guide rail 603, and a limiting mechanism or a buffer element can be configured to prevent problems such as over-travel interference and grinding wheel impact during the movement process.

[0059] Exemplarily, the feeding cylinder generally adopts a double-acting structure to ensure that the grinding wheel can not only approach the glass workpiece 1 for grinding, but also automatically retract in the non-processing state, which is convenient for loading and unloading and grinding preparation.

[0060] In addition, for precise control, the stroke of the feeding cylinder can be adjusted in combination with a solenoid valve and a position sensor. If higher process requirements are needed, it can also be upgraded to a servo electric cylinder or a ball screw module to achieve high-resolution displacement control. The connecting arm body can adopt a rectangular steel pipe or aluminum profile cavity structure, taking into account both light weight and rigid strength, and can be internally provided with wiring channels or air pipe passages to improve the aesthetics and anti-interference ability of the whole machine.

[0061] Exemplarily, in a working environment, to ensure the reliability and durability of the grinding mechanism, an industrial-grade feed cylinder with fast response, strong earthquake resistance, and corrosion resistance should be selected; at the same time, a dust cover and a drainage structure should be equipped to effectively prevent dust and water mist from entering the cylinder cavity and causing jamming or wear. Moreover, if a double-grinding-wheel structure is adopted, special attention should be paid to the synchronous control of the cylinders on both sides of the connecting arm to avoid grinding deviation caused by the imbalance of the grinding wheel angle and affect the machining accuracy and product consistency.

[0062] In this embodiment, the first connecting arm 100a and the second connecting arm 100b are oppositely arranged along the first direction (i.e., longitudinally / axially). The first connecting portion is located above the second connecting arm 100b, and a feed cylinder is provided at one end of each of them on the same side. Each feed cylinder is vertically fixed to one end of the corresponding connecting arm. By oppositely arranging the first connecting arm 100a and the second connecting arm 100b along the first direction in this embodiment, compared with the traditional lateral opposite arrangement, the occupied space of the grinding mechanism in the transverse direction can be significantly reduced, the structure is more compact, which is beneficial to improving the overall machine integration; at the same time, through the independent control of the double feed cylinders, the first grinding wheel 101a and the second grinding wheel 101b can be moved away from or closer to each other, which is beneficial to realizing high-quality and high-efficiency automatic grinding operations.

[0063] In some embodiments, as Figure 2 、 Figure 3 and Figure 21 shown, the grinding wheel set 101 is located between the first connecting arm 100a and the second connecting arm 100b. The first grinding wheel 101a and the second grinding wheel 101b are respectively rotatably connected to the ends of the first connecting arm 100a and the second connecting arm 100b away from the feed cylinder through their respective rotating shafts; a grinding wheel motor 103 is provided on each of the first connecting arm 100a and the second connecting arm 100b, and is respectively connected to the rotating shaft of the corresponding first grinding wheel 101a / second grinding wheel 101b through a multi-wedge belt 102 to drive the first grinding wheel 101a / second grinding wheel 101b to rotate.

[0064] Exemplarily, each grinding wheel is installed on the rotating shaft through its own central shaft hole and is connected to the rotating shaft by a bearing assembly provided at the end of the connecting arm to provide rotational support and at the same time achieve smooth and stable high-speed rotation.

[0065] The grinding wheel rotating shaft and the grinding wheel motor 103 are connected by a multiple-wedge belt 102 for transmission. The motor is usually installed on the side or back of the connecting arm, and a synchronous transmission system is formed with the rotating shaft through the multiple-wedge belt 102. It should be noted that the multiple-wedge belt 102 is widely used in glass grinding scenarios with compact space and high load requirements due to its high transmission efficiency, good flexibility, and ability to adapt to high speed and high torque. To ensure the stability of transmission, a tensioning wheel or a tensioning seat structure can be equipped to ensure that the multiple-wedge belt 102 always maintains an appropriate tension and prevent slipping or power loss during operation.

[0066] Exemplarily, the grinding wheel motor 103 can adopt a variable-frequency speed-regulating motor or a servo motor to achieve precise adjustment of the grinding wheel speed, so as to adapt to glass processing technologies with different thicknesses, materials, or chamfering requirements.

[0067] The material of the rotating shaft can be selected as quenched and tempered alloy steel (such as 40Cr), and surface quenching and chrome plating treatments are carried out to improve its wear resistance and corrosion resistance. The installation form of the grinding wheel can, according to actual requirements, adopt the flange + fastening nut method, or be configured with a positioning key and a limit ring to ensure that the grinding wheel does not loosen, shift, or axially jump under high-speed rotation.

[0068] Exemplarily, by arranging the grinding wheel set 101 in the space area between the first connecting arm 100a and the second connecting arm 100b, the existing spacing space between the connecting arms can be utilized to arrange the two grinding wheels in a staggered manner along the first direction, avoiding the problem of volume expansion caused by external arrangement, significantly compressing the lateral dimension of the whole machine, and making the entire grinding unit more compact and with a higher integration degree. Moreover, this arrangement form also facilitates the centralized installation of supporting components such as the grinding wheel motor 103, the rotating shaft, and the tensioning mechanism inside or on the back of the connecting arm, further improving the internal utilization rate of the structure and avoiding interference between components.

[0069] In this embodiment, the grinding wheel set 101 is located between the first connecting arm 100a and the second connecting arm 100b. The first grinding wheel 101a and the second grinding wheel 101b are respectively rotationally connected to one end of the first connecting arm 100a and the second connecting arm 100b far from the feed cylinder through their respective rotating shafts; a grinding wheel motor 103 is provided on each connecting arm, and the grinding wheel motor 103 is connected to the rotating shaft of the corresponding grinding wheel through a multiple-wedge belt 102. In this embodiment, by compactly arranging the grinding wheel set 101 between the two connecting arms, the installation space is effectively saved; at the same time, the precise and high-speed operation of the grinding wheel is realized by the drive of the independent grinding wheel motor 103, thereby improving the stability of the grinding operation and the compactness and integration degree of the overall equipment.

[0070] Based on the same inventive concept, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 15 and Figure 21 As shown in Figure 15 and Figure 21 , the present application also provides a vertical glass grinding assembly 01, including: A workpiece transportation module 008, which is sequentially provided with a first station 5a, a second station 5b, and a third station 5c along the conveying direction of the glass workpiece to transport the glass workpiece 1; A starting edge grinding head module 001, which is oppositely arranged with respect to the first station 5a and performs a lifting motion in the vertical direction to grind the starting edge 11 of the glass workpiece 1; A base edge grinding head module 002 and a moving edge grinding head module 003, both of which are oppositely arranged with respect to the second station 5b, and the moving edge grinding head module 003 is arranged above the base edge grinding head module 002 in the vertical direction; wherein, the base edge grinding head module 002 is fixed with respect to the second station 5b to grind the base edge 13 of the glass workpiece 1; the moving edge grinding head module 003 adjusts its position in the vertical direction with respect to the second station 5b to grind the top edge 12 of the glass workpiece 1; An end edge grinding head module 004, which is oppositely arranged with respect to the third station 5c and performs a lifting motion in the vertical direction to grind the end edge 14 of the glass workpiece 1; Wherein, a vertical glass grinding mechanism 010 as described above is provided in each of the starting edge grinding head module 001, the base edge grinding head module 002, the moving edge grinding head module 003, and the end edge grinding head module 004 to form a grinding angle a corresponding to each edge of the glass workpiece 1.

[0071] Exemplarily, it further includes a grinding head lifting module 006, which is arranged in parallel with the workpiece transportation module 008 in a direction perpendicular to the conveying direction of the glass workpiece 1, and includes a first lifting support beam 601a and a second lifting support beam 601b that are oppositely arranged along the conveying direction of the glass workpiece; the positive projection of the first lifting support beam 601a in a direction perpendicular to the conveying direction of the glass workpiece 1 is located between the first station 5a and the second station 5b on the workpiece transportation module 008, and the positive projection of the second lifting support beam 601b is located between the second station 5b and the third station 5c; in addition, the workpiece transportation module 008 and the top and bottom ends of the grinding head lifting module 006 can be fixedly connected through a top connection frame 009 and a base 007 respectively.

[0072] Among them, the starting-edge grinding head module 001, the base-edge grinding head module 002, the moving-edge grinding head module 003, and the ending-edge grinding head module 004 are located between the workpiece transportation module 008 and the grinding head lifting module 006; specifically, the starting-edge grinding head module 001 is located at the end of the first station 5a and is slidably connected to the side of the first lifting support beam 601a close to the first station 5a to perform lifting movement in the vertical direction; the base-edge grinding head module 002 is located at the second station 5b and is fixedly connected to the opposite sides of the first lifting support beam 601a and the second lifting support beam 601b respectively; the moving-edge grinding head module 003 is located at the second station 5b and is arranged above the base-edge grinding head module 002 in the vertical direction, and its two ends are slidably connected to the opposite sides of the first lifting support beam 601a and the second lifting support beam 601b respectively to perform lifting movement in the vertical direction; the ending-edge grinding head module 004 is located at the head of the third station 5c and is slidably connected to the side of the second lifting support beam 601b close to the third station 5c to perform lifting movement in the vertical direction.

[0073] Exemplarily, the second station 5b is also provided with a sensor for detecting the size of the glass workpiece 1; detection devices, such as detection rods 107, are provided in the starting-edge grinding head module 001, the base-edge grinding head module 002, the moving-edge grinding head module 003, and the ending-edge grinding head module 004 to monitor the position of the grinding wheel and the grinding angle a in real time.

[0074] Exemplarily, in the vertical glass grinding mechanism 010 of each grinding head module, the orientations of the grinding angles a corresponding to the respective edges of the glass workpiece 1 are different. In addition, to meet the grinding requirements of small-sized glass workpieces 1, at least one of the grinding head modules is provided with a supporting wheel 111. Since there is a fixed spacing between each station, when the size of the glass workpiece 1 is smaller than this spacing, there is a risk of suspension or falling during the workpiece transportation process. For this reason, the supporting wheel 111 can be lifted and lowered together with the grinding head module to adjust its position, and move down to the gap area between adjacent stations after grinding is completed, effectively filling the spacing to form a continuous bearing surface, thereby ensuring the stable support and smooth transition of small-sized glass during transportation and avoiding the occurrence of dropping or jamming phenomena.

[0075] Exemplarily, transmission racks 602 are respectively provided on both sides of the first lifting support beam 601a and the second lifting support beam 601b, and servo drive devices are provided on the corresponding sides of the starting-edge grinding head module 001, the moving-edge grinding head module 003, and the ending-edge grinding head module 004 to cooperate with them, and the two move up and down in the vertical direction by cooperating with the lifting transmission gear 108. The servo drive device includes a third worm and gear reducer 104 and a second servo motor 105 that cooperate with each other; the servo drive device is arranged adjacent to the vertical glass grinding mechanism 010.

[0076] In addition, linear guide rails 603 may be provided on the surfaces of the first lifting support beam 601a and the second lifting support beam 601b. Corresponding linear guide rail sliders 109 are provided in the starting edge grinding head module 001, the base edge grinding head module 002, the moving edge grinding head module 003, and the ending edge grinding head module 004 to form a sliding connection structure. This design can not only significantly improve the guiding accuracy and stability of each grinding head module during the lifting process, but also effectively reduce the shaking and yaw during operation, ensuring that the grinding wheel always contacts the glass workpiece 1 in a stable posture, thereby improving the consistency of grinding, the surface quality, and the reliability of the overall operation of the equipment.

[0077] The vertical glass grinding assembly 01 of this embodiment integrates a glass transportation system, a grinding head lifting system, and multiple grinding modules, aiming to achieve efficient grinding of the four sides of the glass respectively. The workpiece transportation module 008 is sequentially provided with three workstations along the glass conveying direction: the first workstation 5a is used for grinding the starting edge 11 of the glass, the second workstation 5b simultaneously grinds the bottom edge 13 and the top edge 12, and the third workstation 5c grinds the ending edge 14.

[0078] In addition, the workpiece transportation module 008 can ensure the precise docking of the glass between each workstation through the positioning reference and the limiting device, providing a stable processing basis for subsequent grinding.

[0079] This embodiment will be described in combination with the grinding process of each side of the glass workpiece 1. When the glass workpiece 1 enters the first workstation 5a and stops at the preset position, the starting edge grinding head module 001 is activated, and the driving member 110 pushes the first grinding angle a1 formed thereby to slowly approach the starting edge 11 of the glass workpiece 1; the detection rod 107 monitors in real time whether it contacts. When the detection signal confirms the contact, the starting edge grinding head module 001 immediately performs a lifting movement in the vertical direction to complete the grinding of the starting edge 11. After the grinding is completed, the starting edge grinding head module 001 moves upward to vacate space for the continuous conveyance of the glass.

[0080] After entering the second workstation 5b, the glass size detection sensor is immediately activated to obtain the height information of the glass workpiece 1, which is used to adjust the vertical position of the moving edge grinding head module 003 to the corresponding height. The third grinding angle a3 formed by this moving edge grinding head module 003 cooperates with the second grinding angle a2 formed by the fixed base edge grinding head module 002 below, and simultaneously makes a fitting contact with the top edge 12 and the bottom edge 13 of the glass workpiece 1.

[0081] After the above grinding angle is adjusted and the contact is confirmed, the glass workpiece 1 passes through the second workstation 5b at a constant speed, and the moving edge grinding head module 003 and the base edge grinding head module 002 respectively perform synchronous "follow-up type" continuous grinding on the top edge 12 and the bottom edge 13.

[0082] Subsequently, the glass workpiece 1 enters the third station 5c and stays again. The end-edge grinding head module 004 starts to operate. The fourth grinding angle a4 formed by it slowly approaches the end-edge 14 of the glass workpiece 1 under the control of the driving member 110. When contact is detected, the end-edge grinding head module 004 performs vertical lifting and lowering to grind the end-edge 14.

[0083] After grinding is completed, the end-edge grinding head module 004 moves upward. The glass workpiece 1 finishes grinding of its four edges and can continue to flow to the subsequent processes.

[0084] In the vertical glass grinding assembly 01 of this embodiment, it includes a workpiece transportation module 008 and multiple grinding modules arranged in sequence along the conveying path. The workpiece transportation module 008 is successively provided with a first station 5a, a second station 5b, and a third station 5c along the glass workpiece conveying direction, for continuously conveying the glass workpiece 1. The starting-edge grinding head module 001 is disposed opposite to the first station 5a and can move up and down in the vertical direction, for grinding the starting-edge 11 of the glass workpiece 1. The base-edge grinding head module 002 and the moving-edge grinding head module 003 are both disposed opposite to the second station 5b. The former is fixedly installed for grinding the base-edge 13 of the glass workpiece 1, and the latter is located above it and can move up and down in the vertical direction, for grinding the top-edge 12. The end-edge grinding head module 004 is disposed opposite to the third station 5c and also has the function of moving up and down in the vertical direction, for grinding the end-edge 14. A vertical glass grinding mechanism 010 is provided in each of the four grinding head modules, which can form a grinding angle a matching the glass edge between the grinding wheels. Through the above structural arrangement in this embodiment, the glass workpiece 1 realizes sequential and efficient grinding of its four edges during continuous conveying. Multiple grinding stations cooperate with each other, without manual flipping or interruption, significantly improving the processing efficiency and automation level, while ensuring the consistency of grinding quality and the accuracy of edge forming.

[0085] In some embodiments, as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 21 shown, the grinding angle a formed in the starting-edge grinding head module 001 is the first grinding angle a1, and its opening faces the opposite direction of the glass workpiece 1 conveying direction, so that the first grinding angle a1 forms a sliding contact or tangential contact with the starting-edge 11 of the glass workpiece 1, and moves up and down in the vertical direction to grind the starting-edge 11; The grinding angle α formed in the base edge grinding head module 002 is the second grinding angle α2, and its opening faces upward in the vertical direction, so that the second grinding angle α2 forms a sliding contact or a tangential contact with the base edge 13 of the glass workpiece 1, and grinds the base edge 13 when the glass workpiece 1 moves along the glass workpiece conveying direction; The grinding angle α formed in the moving edge grinding head module 003 is the third grinding angle α3, and its opening faces downward in the vertical direction, so that the third grinding angle α3 forms a sliding contact or a tangential contact with the top edge 12 of the glass workpiece 1, and grinds the top edge 12 when the glass workpiece 1 moves along the glass workpiece conveying direction; The grinding angle α formed in the end edge grinding head module 004 is the fourth grinding angle α4, and its opening faces the glass workpiece 1 conveying direction, so that the fourth grinding angle α4 forms a sliding contact or a tangential contact with the end edge 14 of the glass workpiece 1, and grinds the end edge 14 by lifting and lowering in the vertical direction; At least one of the starting edge grinding head module 001, the base edge grinding head module 002, the moving edge grinding head module 003, and the end edge grinding head module 004 is internally provided with a pressing wheel device 106 to clamp and fix the glass workpiece 1.

[0086] Exemplarily, in this embodiment, a complete glass four-side grinding path is constructed by the grinding angles α (i.e., the first to fourth grinding angles) formed inside the four grinding head modules. Specifically, the first grinding angle α1 inside the starting edge grinding head module 001 opens in the opposite direction of the glass workpiece 1 conveying direction, forming a "facing the workpiece" contact, and can perform sliding or tangential grinding on the starting edge 11 of the glass by vertical lifting; the second grinding angle α2 is formed by the base edge grinding head module 002, its opening faces upward, corresponding to the glass base edge 13, to achieve continuous grinding during the glass movement; the third grinding angle α3 is formed by the moving edge grinding head module 003 located directly above it, with the angle opening downward, and realizes adaptive grinding of the glass top edge 12 at different heights through lifting adjustment; the fourth grinding angle α4 is located in the end edge grinding head module 004, its opening faces the glass workpiece 1 conveying direction, and grinds the glass end edge 14 by lifting and lowering in the vertical direction, echoing the starting edge 11 at the beginning and end.

[0087] It should be noted that these grinding angles α are all formed by two grinding wheels arranged oppositely, and their included angle and orientation can be adjusted through the internal connecting arms. Due to the vertical arrangement method, the grinding angle α essentially presents a deep grinding area, and its orientation design determines the contact method and path matching when contacting the glass edge. During the entire grinding process, the first grinding angle α1 and the fourth grinding angle α4 use the lifting and lowering movement method to grind the static starting edge 11 and end edge 14 respectively, while the second grinding angle α2 and the third grinding angle α3 are synchronized with the conveying and perform "follow-up grinding" operations to achieve efficient processing of the straight edge.

[0088] For example, the four grinding angles correspond to the four edges of the glass workpiece 1, with the starting edge grinding head module 001, the base edge grinding head module 002, the moving edge grinding head module 003, and the ending edge grinding head module 004 performing the grinding tasks. The starting edge grinding head module 001 and the ending edge grinding head module 004 are equipped with synchronized lifting and lowering control capabilities, allowing them to simultaneously grind the starting edge 11 and ending edge 14 of different glass workpieces 1 according to the conveying rhythm. Meanwhile, a glass workpiece 1 with its starting edge ground has already been placed in the second workstation 5b and is ready for grinding. The coaxially arranged moving edge grinding head module 003 and the base edge grinding head module 002 form a bidirectional clamping structure, which grinds the top edge 12 and bottom edge 13 synchronously as the glass continues to move. The entire system operates in a coordinated manner under a unified beat control mechanism, achieving synchronous grinding of three different glass workpieces 1 in three stations - the first station 5a completes grinding of the starting edge 11, the second station 5b completes grinding of the top edge 12 and bottom edge 13, and the third station 5c completes grinding of the ending edge 14, and then enters the next station in sequence; a new glass workpiece 1 can also enter the first station 5a, realizing a continuous and efficient multi-station linkage grinding process.

[0089] For example, to achieve flexible clamping and stable operation, each grinding head module is equipped with at least one pressure roller assembly 106, such as an elastic rubber roller, pneumatic roller, or tension roller. These pressure roller assemblies 106 are typically positioned in front of or to the side of the grinding angle a. Adjustable pressure, tailored to the glass thickness, prevents displacement or vibration of the workpiece before it enters the grinding angle a. Furthermore, the pressure roller assembly 106 must be positioned away from the grinding wheel's path and constructed from wear-resistant, low-adhesion materials to ensure long-term stable operation.

[0090] This embodiment sets the directions and contact modes of the four grinding angles, wherein the contact modes of the respective grinding angles with the respective edges of the glass workpiece 1 are reasonable, and the conveying movement and lifting adjustment are coordinated to realize efficient, stable and automated edge grinding operations on the four edges of the glass, thereby significantly improving the processing efficiency, processing accuracy and the continuity and reliability of the overall operation of the equipment.

[0091] In some embodiments, as Figure 16 、 Figure 17 and Figure 21 As shown, the workpiece transport module 008 includes a plurality of conveying roller groups, which are evenly distributed in the first workstation 5a, the second workstation 5b and the third workstation 5c; the bottom end of each conveying roller group is connected to a bottom conveying wheel group to support the glass workpiece 1 together with the conveying roller group and push it to move along the glass workpiece conveying direction.

[0092] Exemplarily, one side of the conveying roller group is fixedly connected to the main frame 801, and the other side is in sliding contact with the glass surface of the glass workpiece 1, playing a role of lifting and pushing; while the bottom conveying wheel group is located below the glass workpiece 1, abuts against the bottom edge 13 of the glass workpiece 1, and the bottom conveying wheel group is arranged perpendicular to the plane in which the glass workpiece 1 is conveyed, and constructs a stable conveying channel for jointly supporting and conveying the glass workpiece 1 with the conveying roller group, ensuring that the glass workpiece 1 maintains a stable posture and continuous flow throughout the grinding path.

[0093] Exemplarily, the bottom end of each conveying roller group is connected to the corresponding bottom conveying wheel group in the form of synchronous belt wheels, couplings or common drive shafts, etc. All power is finally concentrated on the bottom / top drive platform, controlled by a unified main drive motor 804, and the conveying speed can be coordinately adjusted through a frequency converter.

[0094] In addition, the entire conveying system supports zone control. The roller groups at the three workstations can independently set the acceleration and deceleration logics to ensure that the glass can start and stop slowly at the initial entry and final exit stages, and at the same time maintain synchronization with the grinding speed at the middle workstation, thereby improving the consistency of edge processing and the surface quality.

[0095] Exemplarily, the conveying roller group can be provided with a height fine-tuning mechanism or an elastic floating bracket for automatically compensating for the glass thickness fluctuation and improving the adhesion between the glass and the roller surface. At the same time, the bottom conveying wheel group can adopt a transmission structure of "driving wheel + driven wheel", controlled by direct connection of servo drive or sprocket drive, to ensure that the movement rhythm is accurately synchronized with the upper roller group.

[0096] Exemplarily, to ensure long-term stable operation, the surface of the conveying roller 802 can be coated with a medium-hard PU rubber layer, which has good anti-slip performance and protects the glass surface from being scratched; at the same time, the roller shaft connection should adopt a detachable locking structure or a floating support for easy later maintenance; all drive chains and drive motors should be equipped with dust covers and liquid discharge channels to prevent glass grinding debris and coolant from invading and causing wear.

[0097] In addition, a photoelectric detector or a pressure sensor can be installed in the conveying roller group to realize real-time monitoring of the glass in-place state, and link the control system to execute functions such as automatic forward and backward movement, shutdown or abnormal alarm.

[0098] The conveying method in this embodiment has significant progress compared with the traditional single-sided belt conveying scheme. Among them, the double-structure support design of the conveying roller group and the bottom conveying wheel group greatly improves the stability during glass transportation, effectively preventing problems such as deformation, slipping, and warping of the glass plate; moreover, the double-structure support design is also more suitable for the transmission of high-weight and large-size glass. In addition, the conveying roller group is evenly arranged, making the transition between workstations smooth and the whole machine operate more coherently.

[0099] In some embodiments, such as Figure 16 、Figure 17 and Figure 21 As shown, each of the conveying roller groups includes a plurality of conveying rollers 802 arranged in parallel along the conveying direction of the glass workpiece and rotating synchronously with each other; each of the bottom conveying wheel groups includes a plurality of bottom conveying wheels 803, each bottom conveying wheel 803 is located between two adjacent conveying rollers 802, and is connected to each other through a bevel gear 810; A pressure wheel mechanism 005 is vertically provided on one side of each bottom conveying wheel group close to the grinding head lifting module 006 to cooperate with the conveying roller group to clamp and fix the glass workpiece 1.

[0100] Exemplarily, the conveyor roller assembly is positioned relative to the glass plane of the glass workpiece 1 and comprises a plurality of parallel conveyor rollers 802. Optionally, each conveyor roller assembly includes at least three conveyor rollers 802. These rollers are arranged along the glass conveying direction and rotate at a constant speed through a linkage structure, primarily providing propulsion and support for the glass. The bottom conveyor wheel 803 is positioned in the gap between adjacent conveyor rollers 802, perpendicular to the glass plane of the glass workpiece 1, and abuts against the bottom edge 13 of the glass workpiece 1. Its interior can be driven in series with a bevel gear 810 for coordinated driving. The pressure wheel mechanism 005 is positioned on the side of the bottom wheel assembly near the grinding head lifting module 006, vertically pressing the glass from far to near in a direction perpendicular to the glass plane to prevent it from floating, shaking, or deflecting during the grinding process.

[0101] In this structural design, the workpiece transport module 008 is further refined into a clamping transmission system composed of a conveying roller group, a bottom conveying wheel group and a pressure wheel mechanism 005 to achieve steady-state transportation and high-precision guidance of the glass workpiece 1 during the grinding process.

[0102] For example, the conveyor rollers 802 are interconnected via a sprocket assembly (which may include a driving sprocket 806 and a driven sprocket 807) and / or a worm gear 808 and worm gear 809 system. Each conveyor roller 802 is also connected to a main drive motor 804 and a second worm gear reducer 805, with variable frequency motor speed regulation to achieve tachometer control of the entire conveyor path. The bottom conveyor roller 803 is connected to the conveyor roller assembly via a bevel gear 810 and a conveyor sprocket 811, typically arranged in a V-shape or staggered configuration. This not only facilitates insertion into the gaps between the rollers, but also facilitates the spatial staggering of multiple wheels, improving transmission stability and compactness.

[0103] The pressure wheel mechanism 005 can adopt a pressure wheel cylinder 503 + pressure wheel 502 structure connected to the pressure wheel bracket 504, which can be a floating type or a pneumatic clamping type to ensure continuous and flexible pressure on the glass. Symmetrical auxiliary wheels 501 can also be provided at both ends of the pressure wheel bracket 504 to assist in clamping the glass workpiece 1.

[0104] Exemplarily, several key details need to be noted in the application. For example: The bevel gear 810 should be refueled and maintained regularly, and equipped with a tooth cover to prevent glass debris and coolant from invading the tooth cavity; the pressure of the pressing wheel should be set according to the thickness of the workpiece to avoid crushing or deforming the glass; the system should be equipped with an overload protection device and a limit inductor to prevent accidental impacts during operation.

[0105] In addition, to improve the process switching efficiency, the conveying component should support a quick-change structure to meet the flexible production requirements of rapid switching of multiple specifications of glass; rotational speed sensors can be installed on each rotatable component within the system to achieve dynamic monitoring and feedback control of the conveying speed, providing a stable, efficient, and safe physical basis for the entire grinding system.

[0106] In each of the present embodiments, each of the conveying roller groups includes a plurality of conveying rollers 802 arranged in parallel along the conveying direction of the glass workpiece and rotating synchronously with each other; each of the bottom conveying wheel groups includes a plurality of bottom conveying wheels 803, and the bottom conveying wheels 803 are arranged between two adjacent conveying rollers 802 and achieve synchronous transmission with each other through a bevel gear 810 mechanism, effectively improving the transmission efficiency and operation stability; in addition, on one side of each bottom conveying wheel group close to the corresponding grinding head lifting module 006, a pressing wheel mechanism 005 is vertically provided, forming a clamping structure with the conveying roller group to achieve stable positioning and continuous guiding of the glass workpiece 1. Through the coordinated cooperation of multiple groups of conveying elements in the present embodiment, it is ensured that the glass workpiece 1 runs smoothly and is clamped reliably during high-speed conveying and grinding, significantly improving the processing efficiency, grinding accuracy, and automation stability of the overall system.

[0107] Based on the same inventive concept, as Figure 18 、 Figure 19 、 Figure 20 and Figure 21 shown, the present application further provides a vertical glass grinding system, including: The vertical glass grinding assembly 01 as described in any one of the above; An in-feed conveying assembly 02 and an out-feed conveying assembly 03, both including a conveying panel 201 and a conveying mechanism 200 located at the bottom end of the conveying panel 201; a plurality of pulleys 209 are provided on the surface of the conveying panel 201 to assist the conveying mechanism 200 in conveying the glass workpiece 1; Wherein, the in-feed conveying assembly 02, the vertical glass grinding assembly 01, and the out-feed conveying assembly 03 are sequentially connected along the conveying direction of the glass workpiece.

[0108] Exemplarily, the present system is sequentially composed of three functional modules: an in-feed conveying assembly 02, a vertical glass grinding assembly 01, and an out-feed conveying assembly 03. This structural design aims to achieve a complete automated processing process from the introduction of the glass workpiece 1, high-precision grinding of the four sides, to the output of the finished glass.

[0109] Exemplarily, the sheet feeding and conveying assembly 02 includes a conveying panel 201 and a conveying mechanism 200 provided at its bottom. Specifically, multiple sets of pulleys 209 are provided on the conveying panel 201. The pulleys 209 can be made of wear-resistant polyurethane or polymer materials, have good antifriction performance, can effectively prevent glass from being scratched, and provide uniform lifting support for the glass during conveying.

[0110] The conveying mechanism 200 can be composed of a conveying driving synchronous pulley 203, a conveying driven synchronous pulley 202, a first worm and worm gear reducer 204, a first servo motor 205, and a conveying synchronous belt 206, and can achieve stable and precise transmission drive. The conveying mechanism 200 and the conveying panel 201 of the sheet feeding and conveying assembly 02 can be jointly supported by a conveying frame 207, a support pull rod 208, and a base 007 frame 210 to form an import platform with strong rigidity and stable structure. The main function of this assembly is to smoothly import the glass workpiece 1 from the previous production line into the grinding area and preliminarily stabilize the workpiece posture.

[0111] It should be noted that the sheet discharging and conveying assembly 03 has a similar structural design to the sheet feeding and conveying assembly 02. The sheet discharging and conveying assembly 03 is responsible for smoothly discharging the glass workpiece 1 that has completed the edge grinding process to the subsequent work section or the automatic material collection device, ensuring the smooth connection of the entire processing flow.

[0112] The three assemblies are arranged in sequence along the glass workpiece conveying direction in space and can be integrally integrated through a unified mechanical platform or a track base. The tail end of the sheet feeding and conveying assembly 02 is precisely aligned with the first station 5a of the vertical glass grinding assembly 01, and the front end of the sheet discharging and conveying assembly 03 is naturally connected to the third station 5c of the vertical glass grinding assembly 01, thereby realizing the seamless transition transportation of the glass workpiece 1.

[0113] The vertical glass grinding system in this embodiment includes a vertical glass grinding assembly 01, a sheet feeding and conveying assembly 02, and a sheet discharging and conveying assembly 03. Among them, both the sheet feeding and conveying assembly 02 and the sheet discharging and conveying assembly 03 include a conveying panel 201 and a conveying mechanism 200 provided at its bottom end. The surface of the conveying panel 201 is provided with several pulleys 209 for assisting the conveying mechanism 200 to smoothly convey the glass workpiece 1; the above-mentioned sheet feeding and conveying assembly 02, vertical glass grinding assembly 01, and sheet discharging and conveying assembly 03 are sequentially connected along the conveying direction of the glass workpiece 1 to form a complete and coherent processing link. The structural design of this embodiment realizes the automatic continuous conveying and processing of the glass workpiece 1 from sheet feeding, grinding to sheet discharging, avoids the positioning errors and time losses caused by manual handling or mid-way pauses, and significantly improves the processing efficiency, operation fluency, and automation level of the overall system. In addition, the vertical glass grinding design can be directly connected in series with the current mainstream vertical insulating glass production line.
