Description

Technical Field

[0001] This invention relates to the field of insulated glass assembly equipment technology, specifically a suction cup type alignment mechanism for assembling insulated glass sheets. Background Technology

[0002] In the processing of glass products, non-melting methods are often required to join glass to glass or glass to other materials. Taking the processing of insulated glass as an example, a spacer carrying the adhesive material can be placed in a predetermined joining area of ​​the first glass plate. Then, the joining surface of the second glass plate is moved towards the first glass plate, so that the adhesive material contacts the glass plates respectively, and an adhesive connection is formed between the glass plates and the spacer by pressing. Whether the joining areas of the two glass plates correspond accurately will affect the contact position of the adhesive material and the pressure state of the joining interface. Therefore, the relative positions of the glass plates need to be calibrated before pressing.

[0003] Existing glass plate joining equipment typically uses suction cups to hold the glass plates to be joined, and a moving mechanism moves the glass plate to the joining station, then brings it closer to another glass plate along the joining direction. Some equipment also includes positioning components or detection elements to adjust the position of the glass plates to be joined, so that the predetermined joining areas of the two glass plates correspond to each other.

[0004] However, existing suction cup glass bonding equipment cannot guarantee accurate alignment of two glass plates before pressing. The position of the suction cup support component cannot directly reflect the actual position of the glass plate to be bonded. Affected by the initial position of the glass plate, the adsorption position, and the movement error of the mechanism, even if the support component reaches the preset position, there may still be a positional deviation between the two glass plates, which will affect the contact position of the bonding material and the subsequent pressing effect.

[0005] To address this, a suction cup-type alignment mechanism for laminating insulating glass is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a suction cup alignment mechanism for laminating insulating glass, solving the problem that existing suction cup glass laminating equipment cannot guarantee accurate alignment of two glass plates before pressing. This invention uses the same mechanical reference for the actual edges of the first and second glass plates, and performs planar position correction and current position locking before the second glass plate contacts the bonding material. This distinguishes the actual bonding position of the glass plates from the position of the suction cup bearing mechanism itself, thereby reducing the impact of suction cup adsorption position and mechanism movement errors on the alignment accuracy of the two glass plates before pressing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A suction cup-type alignment mechanism for bonding insulating glass sheets is characterized by comprising a support plate for holding a first glass plate, a spacer frame provided in the area of ​​the first glass plate to be pressed, the spacer frame carrying adhesive material for joining the two glass plates; a lifting drive unit drives a floating plate to perform bonding and pressing actions via a lower support plate, a support locking assembly switches the floating plate between floating and locked states, a suction cup assembly of the floating plate engages with the non-bonding surface of the second glass plate, so that the bonding surfaces of the two glass plates are opposite each other; a main reference assembly and a secondary reference assembly are each provided with two and one reference roller assembly, the coaxial lower reference roller and upper reference roller respectively contact the corresponding edges of the two glass plates to establish a common bonding reference; when the second glass plate is not in contact with the adhesive material, the main push assembly and the secondary push assembly sequentially correct the planar position deviation of the two glass plates, after locking the reference assembly and the push assembly retract, the lifting drive unit presses the bonding material onto the bonding surface of the second glass plate, so that the adhesive material forms a non-molten bond with the two glass plates respectively.

[0008] This invention enables the first and second glass plates to respectively contact their corresponding lower and upper reference rollers via their actual edges. A common mechanical bonding reference is established between the two glass plates using the same reference roller assembly, rather than directly using the theoretical position of the suction cup assembly or floating plate as the bonding positioning basis for the second glass plate. The second glass plate is held by the suction cup assembly and undergoes limited planar adjustment with the floating plate before contacting the bonding material. The main and secondary pushing components sequentially push the second glass plate towards the corresponding reference, establishing a corresponding relationship between the areas to be bonded on the two glass plates. After calibration, the floating plate is locked in its current position, and then the reference assembly and pushing assembly are withdrawn from the pressing motion area. Finally, a lifting drive component moves the second glass plate, now in the calibrated position, towards the first glass plate. Thus, the planar alignment of the glass plates and subsequent bonding pressing are completed in stages, establishing and maintaining the relative positional relationship between the two glass plates before formal contact with the bonding material.

[0009] Preferably, the main reference assembly includes a main reference guide rail, a main reference moving base, a main reference vertical back plate, and a main reference upper suspension beam. The main reference moving base moves along the main reference guide rail toward or away from the pressing area of ​​the first glass plate. The main reference vertical back plate connects the main reference moving base and the main reference upper suspension beam. Two reference roller assemblies are spaced apart along one edge of the pressing area. The secondary reference assembly includes a secondary reference guide rail, a secondary reference moving base, a secondary reference vertical back plate, and a secondary reference upper suspension arm. The secondary reference moving base moves along the secondary reference guide rail toward or away from the pressing area. The secondary reference vertical back plate connects the secondary reference moving base and the secondary reference upper suspension arm. A reference roller assembly is disposed on the secondary reference upper suspension arm. The main reference guide rail and the secondary reference guide rail extend along the normal directions of the mutually orthogonal edges of the pressing areas, so that the main reference assembly defines the position and direction of one side of the pressing area at two points, and the secondary reference assembly defines the orthogonal direction position at one point, and establishes a common bonding reference for the non-melting pressing of the first glass plate and the second glass plate before the bonding material contacts the second glass plate.

[0010] Two reference roller assemblies are spaced apart along the same edge, allowing the primary reference assembly to define the position and orientation of that side edge of the glass plate through two mutually spaced contact points. When the second glass plate is subjected to the action of the primary push assembly, it simultaneously completes translational position and attitude correction in that direction. A secondary reference assembly has a reference roller assembly positioned in a direction orthogonal to the primary reference direction, further defining the position in another direction based on the already determined primary direction. Thus, two translational degrees of freedom and one planar rotational degree of freedom of the glass plate are sequentially defined by two primary reference points and one secondary reference point, while avoiding repetitive rigid constraints on multiple edges of the glass plate simultaneously. The primary and secondary reference assemblies advance and retreat along the corresponding edge normals, and can also leave the pressing motion area of ​​the second glass plate after completing the correction.

[0011] Preferably, the reference roller assembly includes a fixed vertical shaft, a lower reference roller, a middle spacer sleeve, and an upper reference roller. The lower and upper reference rollers are independently rotatably mounted on the fixed vertical shaft, and the middle spacer sleeve is located between the lower and upper reference rollers. Before the adhesive material contacts the second glass plate, the lower reference roller abuts against the edge of the first glass plate, and the upper reference roller abuts against the corresponding edge of the second glass plate. The lower and upper reference rollers have the same outer diameter, and their tangential positions facing the corresponding edges are located on the same vertical reference plane. The vertical reference plane constitutes a common bonding reference for the bonding areas of the first and second glass plates, so that the two bonding areas form a corresponding relationship before non-melting bonding.

[0012] The lower and upper reference rollers are mounted on the same fixed vertical axis and have the same outer diameter, ensuring that the tangential positions of the two rollers toward the corresponding glass edges remain consistent vertically. The first glass plate is positioned by its actual edge against the lower reference roller, while the second glass plate is aligned by its corresponding actual edge against the upper reference roller. This allows the two glass plates at different heights to directly reference the same vertical mechanical reference plane, thereby reducing the impact of suction cup adsorption position and suction cup support mechanism installation position deviations on the actual bonding area of ​​the glass plates. Simultaneously, the lower and upper reference rollers rotate independently, allowing each glass plate to roll and engage with its corresponding roller during positioning or alignment, avoiding unnecessary rotational force transmitted between the upper and lower rollers.

[0013] Preferably, it further includes a bottom mounting plate and two sets of reference working limit components respectively corresponding to the main reference component and the secondary reference component. The support plate, the main reference guide rail and the secondary reference guide rail are disposed on the bottom mounting plate, and the bottom mounting plate forms an integrated limit seat corresponding to the main reference component and the secondary reference component respectively. Each set of reference working limit components includes an adjustable limit screw, a rigid stop block and a locking nut for locking the adjustable limit screw installed on the corresponding integrated limit seat. The rigid stop blocks of the two sets of reference working limit components are respectively fixed to the main reference moving base and the secondary reference moving base, and abut against the corresponding adjustable limit screw when the corresponding reference component enters the working position.

[0014] By setting the adjustable limit screw on an integrated limit seat that is fixed to the bottom mounting plate, and allowing the rigid stop block to move with the corresponding reference moving base, the final working position is determined by the physical contact between the rigid stop block and the adjustable limit screw when the main or secondary reference assembly enters the working position. The adjustable limit screw can be used to initially calibrate the position of the reference assembly, while the locking nut maintains its set position after adjustment. This ensures that the working reference of the reference roller assembly is mainly determined by the fixed mechanical stop relationship, reducing the dependence of the reference position on the stopping position error of the drive component itself.

[0015] Preferably, the support locking assembly is configured in three sets arranged in a triangular pattern. The support locking assembly supports the floating plate, and the locking drive assembly switches the floating plate between floating and locked states. Each support locking assembly includes a fixed sleeve fixed to the lower support plate, a lifting support that slides along the axial direction of the fixed sleeve, a universal ball bearing disposed on the top of the lifting support, a lower limit cover fixed to the lower end of the fixed sleeve, a support spring abutting between the lifting support and the lower limit cover, and an annular friction pad disposed on the lower support plate and surrounding the fixed sleeve. Under the action of the support spring, the universal ball bearing extends above the annular friction pad and supports the floating plate. When the floating plate is pressed down, it pushes the universal ball bearing and the lifting support down and into contact with the annular friction pad.

[0016] In the floating state, the support spring pushes the lifting bracket and omnidirectional balls upwards, so that the floating plate is supported by three omnidirectional balls arranged in a triangle and kept separate from the annular friction pad. The omnidirectional balls can roll under planar force, allowing the floating plate, along with the suction cup assembly and the second glass plate, to perform limited planar movement and rotation relative to the lower support plate, absorbing deviations caused by the initial position and suction position of the second glass plate. When the floating plate is subjected to downward pressure, the omnidirectional balls and the lifting bracket retract downwards against the support spring, bringing the floating plate into contact with the annular friction pad. This switches from a low-resistance rolling support state to a friction-constrained state, achieving the switching between floating and locked operating states.

[0017] Preferably, the locking drive assembly includes a compact guide cylinder, a triangular pressure plate, three threaded adjusting rods, and three flat pressure plates. The fixed cylinder body of the compact guide cylinder is mounted on the lifting connecting plate. The movable worktable of the compact guide cylinder is fixedly connected to the triangular pressure plate. The three threaded adjusting rods are respectively located at the three apex corners of the triangular pressure plate. Each threaded adjusting rod has a flat pressure plate at its lower end. The three flat pressure plates are coaxial with three sets of support locking assemblies and are used to apply pressure synchronously from above the floating plate to press the floating plate tightly against the three annular friction pads.

[0018] When the compact guide cylinder actuates, its movable worktable moves the triangular pressure plate vertically, which in turn drives the three planar pressure plates to simultaneously press against the floating plate. The three planar pressure plates correspond to three sets of support and locking assemblies, ensuring that the downward force is transmitted synchronously to the floating plate at the three locking positions, causing the floating plate to press against the annular friction pad at the corresponding location. A threaded adjusting rod allows adjustment of the relative height of each planar pressure plate, facilitating a coordinated pressing action. The locking force is primarily applied perpendicular to the floating plate; therefore, the locking process maintains the already calibrated position of the second glass plate, rather than readjusting its planar position using the pressure plates, thus minimizing lateral disturbance to the existing calibration results caused by the locking action.

[0019] Preferably, it also includes three large-head limiting posts fixed to the lower support plate. The smooth rod of each large-head limiting post passes through a corresponding enlarged circular hole on the floating plate. A radial gap is maintained between the smooth rod and the hole wall of the corresponding enlarged circular hole. The limiting head of the large-head limiting post is located above the floating plate to prevent the floating plate from detaching upward. The floating plate is provided with a suction cup mounting hole, and the lower support plate is provided with a suction cup clearance hole corresponding to the suction cup mounting hole. Each suction cup assembly includes a hollow connecting sleeve that passes through and is fixed to the suction cup mounting hole and a flexible suction cup disposed at the lower end of the hollow connecting sleeve. The hollow connecting sleeve passes through the corresponding suction cup clearance hole.

[0020] A radial clearance is maintained between the guide rod of the large-head limiting post and the enlarged circular hole, allowing the floating plate to undergo limited planar displacement and rotation relative to the large-head limiting post within the normal calibration range, without being restricted by the rigid positioning of the guide rod. The limiting head located above the floating plate forms an axial block when the floating plate tends to detach upwards, thus balancing the floating degree of freedom and the anti-detachment limiting function. The suction cup assembly is fixed to the floating plate, and the hollow connecting sleeve passes through the suction cup clearance hole on the lower support plate, allowing the suction cup assembly to move with the floating plate relative to the lower support plate in a limited manner. Therefore, during the calibration process, the second glass plate, the suction cup assembly, and the floating plate move as a single moving unit, eliminating the need for the suction cup to slide on the surface of the second glass plate for alignment, which helps maintain the adsorption state of the second glass plate.

[0021] Preferably, both the main push-back assembly and the secondary push-back assembly are composed of standard push-back modules. Each standard push-back module includes a push-back guide rail, a push-back movable base, a side-mounted compact cylinder, a square-hole guide seat, a combined push rod, a compression spring, a lateral limit pin, a roller fork, and push-back rollers. The push-back movable base moves along the push-back guide rail, the side-mounted compact cylinder drives the push-back movable base, and the square-hole guide seat is fixed to the push-back movable base. The combined push rod includes an integrally connected square anti-rotation guide section and a cylindrical spring tail rod, and the square anti-rotation guide section slides... The cylindrical spring tail rod is disposed within the square hole guide seat, passing through the rear end spring seat wall of the square hole guide seat. The compression spring is sleeved on the cylindrical spring tail rod, with both ends abutting against the shoulder between the square anti-rotation guide section and the cylindrical spring tail rod and the rear end spring seat wall, respectively. The square hole guide seat is provided with an elongated oval limiting hole, and the transverse limiting pin passes through the elongated oval limiting hole and is fixed to the square anti-rotation guide section to limit the maximum retraction of the combined push rod relative to the square hole guide seat. The roller fork is connected to the front end of the square anti-rotation guide section, and the push roller is rotatably disposed on the roller fork.

[0022] The side-mounted compact cylinder first drives the push-and-move base and the square-hole guide seat to move towards the second glass plate. When the push-and-move roller contacts the edge of the second glass plate, the combined push rod can retract relative to the square-hole guide seat, and the compression spring is compressed between the shoulder of the combined push rod and the rear spring seat wall. This converts part of the overstroke of the drive component into elastic deformation, allowing the push-and-move roller to elastically hold the second glass plate against the corresponding reference. The sliding fit between the square anti-rotation guide section and the square-hole guide seat restricts the rotation of the combined push rod, keeping the movement direction of the push-and-move roller stable. The lateral limit pin and the oblong limit hole limit the maximum retraction of the combined push rod, avoiding excessive compression. The push-and-move roller can rotate, allowing the main push-and-move assembly to complete a directional and angular correction. Then, the secondary push-and-move assembly can continue to push the second glass plate along the main reference direction, thus completing the main and secondary push-and-move actions sequentially and reducing the risk of jamming caused by rigid synchronous clamping.

[0023] Preferably, the system further includes a gantry frame, a vertical lifting guide assembly, and four fixed-length support sleeves. The lifting drive is a central servo electric cylinder. The gantry frame includes a left column, a right column, and a top crossbeam connecting the left and right columns. The vertical lifting guide assembly includes two vertical linear guides respectively installed on the left and right columns, two lifting sliders installed on each vertical linear guide, and two lifting connecting side plates respectively connecting the two lifting sliders on the same side to the lifting connecting plate. The lifting drive is installed on the top crossbeam and its output end is connected to the lifting connecting plate. The lifting connecting plate is connected to the lower bearing plate through four fixed-length support sleeves.

[0024] After the lifting drive unit outputs motion to the lifting connecting plate, the lifting connecting plate synchronously drives the lower bearing plate, along with its cooperating floating plate, suction cup assembly, and second glass plate, to rise and fall via four fixed-length support sleeves. The vertical linear guide rails on the left and right sides guide the lifting connecting plate through two lifting sliders, creating spaced vertical guide positions on both sides, thus limiting lateral offset and tilting of the upper mechanism during lifting. The four fixed-length support sleeves maintain the relative position between the lifting connecting plate and the lower bearing plate, and also form the transmission path for vertical forces during lifting and pressing, allowing the second glass plate, after planar correction and locking, to bond and press against the first glass plate under the constraint of the vertical lifting guide assembly.

[0025] Preferably, the support plate is provided with a shallow negative pressure cavity, an annular sealing groove surrounding the shallow negative pressure cavity, and a lateral vacuum interface communicating with the shallow negative pressure cavity. The shallow negative pressure cavity is used to maintain the position of the first glass plate under negative pressure after the first glass plate is positioned by the lower reference roller. The floating plate is provided with a vacuum distribution block, which has a main interface and four branch interfaces, each of which is connected to a suction cup assembly.

[0026] After the first glass plate is positioned by its actual edge against the lower reference roller, a shallow negative pressure chamber forms a negative pressure through the lateral vacuum interface. Within the sealed area formed by the annular sealing groove, this negative pressure helps to hold the first glass plate toward the support plate. This ensures that even after the main and secondary reference components are withdrawn, the first glass plate retains the position previously determined by the lower reference roller. Therefore, the shallow negative pressure chamber serves to hold the first glass plate after positioning and is not used to change its planar position. The vacuum distribution block then distributes the negative pressure introduced from the main interface to each suction cup assembly, allowing multiple suction cup assemblies to jointly hold the second glass plate. The second glass plate then moves with the floating plate for alignment and subsequent lifting and lowering. Thus, the reference positioning of the first glass plate and the adsorption holding of the second glass plate are achieved through corresponding negative pressure structures.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention sets up a coaxial lower reference roller and an upper reference roller with the same outer diameter in the same reference roller assembly, so that the corresponding edges of the first glass plate and the second glass plate respectively abut against the vertical mechanical reference surface determined by the same fixed vertical axis. This allows the two glass plates to directly establish a common bonding reference based on their actual edges, instead of using the theoretical position of the suction cup assembly or its supporting mechanism as the basis for glass plate alignment. This reduces the influence of the initial position of the glass plates, the suction cup adsorption position, and the mechanism movement error on the correspondence of the areas to be bonded between the two glass plates.

[0028] 2. This invention uses two main reference points spaced apart along one side edge and one secondary reference point set along an orthogonal direction, and coordinates with the main push-fit component and the secondary push-fit component to work in sequence, so that the second glass plate first completes the position and plane rotation angle correction in one direction, and then completes the position correction in another direction. Thus, the two main reference points and one secondary reference point are used to sequentially limit the three plane degrees of freedom of the second glass plate. At the same time, the push-fit component adopts a push-fit structure with elastic retraction and stroke limitation, so that the glass plate can stably fit against the reference and reduce the impact of the stop position error of the drive component and rigid push on the alignment process.

[0029] 3. The present invention uses a support spring, a lifting support, universal ball bearings, and an annular friction pad to form a switchable support and locking structure. During the alignment stage, the floating plate is supported by the universal ball bearings with low resistance, allowing the second glass plate, the suction cup assembly, and the floating plate to perform limited planar translation and rotation as a whole. After the alignment is completed, the floating plate is pressed against the annular friction pad by the locking drive assembly, switching the rolling support state to the friction locking state. This absorbs the initial position and adsorption position deviation without the suction cup sliding relative to the glass plate, and maintains the already formed alignment position.

[0030] 4. This invention performs plane alignment, position locking, edge constraint release, and bonding pressing in sequence. Plane alignment is completed before the second glass plate comes into contact with the bonding material. Then, the floating plate is locked first, and then the main and secondary reference components and the main and secondary push components are released from the pressing motion area of ​​the glass plate. Finally, the lifting drive component drives the second glass plate, which has maintained the calibration position, to move along the pressing direction. This separates the alignment process from the bonding pressing process, avoiding the need to continue lateral alignment after the bonding material has come into contact with the second glass plate. This helps to maintain the correspondence between the areas to be bonded of the two glass plates and the pressure state of the joint interface. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 12 This invention provides a suction cup-type alignment mechanism for laminating insulating glass sheets, the technical solution of which is as follows: A suction cup-type alignment mechanism for bonding insulating glass sheets is characterized by comprising a support plate 2 for holding a first glass plate 3, a spacer frame 4 provided in the area to be pressed of the first glass plate 3, the spacer frame 4 carrying the adhesive material for joining the two glass plates; a lifting drive 8 driving a floating plate 12 via a lower support plate 11 to perform the bonding and pressing action; a support locking assembly 16 switching the floating plate 12 between a floating and locked state; a suction cup assembly 13 of the floating plate 12 engaging with the non-bonding surface of the second glass plate 5, so that the bonding surfaces of the two glass plates are opposite each other; and a main reference assembly. The components 18 and 19 are each provided with two reference roller assemblies and one reference roller assembly 20. The coaxial lower reference roller 202 and upper reference roller 204 contact the corresponding edges of the two glass plates to establish a common bonding reference. When the second glass plate 5 is not in contact with the bonding material, the main push assembly 22 and the secondary push assembly 23 correct the planar position deviation of the two glass plates in sequence. After locking, the reference assembly and the push assembly retract, and the lifting drive 8 presses the bonding material onto the surface of the second glass plate 5 to be bonded, so that the bonding material forms a non-melting bond with the two glass plates respectively.

[0035] Specifically, the first glass plate 3 is placed horizontally on the support plate 2. The spacer frame 4 is pre-set on the side of the first glass plate 3 facing the second glass plate 5. The second glass plate 5 is held by suction cup assembly 13 from the non-adhesive surface and is positioned above the first glass plate 3 along with the floating plate 12. During operation, the main reference assembly 18 and the secondary reference assembly 19 first enter the working position, so that one edge of the first glass plate 3 abuts against two lower reference rollers 202 respectively, and the adjacent edge abuts against another lower reference roller 202. The position and orientation of one side of the first glass plate 3 are determined by two spaced main reference points, and the position of the orthogonal direction is determined by a secondary reference point. Then, the support plate 2 holds the current position of the first glass plate 3, and the main reference assembly 18 and the secondary reference assembly 19 retract to avoid the descending path of the second glass plate 5.

[0036] The lifting drive component 8 lowers the floating plate 12, which holds the second glass plate 5, to above the spacer frame 4. While a gap remains between the second glass plate 5 and the adhesive material, the floating plate 12 switches from a locked state to a floating state. At this time, the second glass plate 5, the suction cup assembly 13, and the floating plate 12, as a single moving unit, can perform limited planar movement and rotation relative to the lower support plate 11. Subsequently, the main reference assembly 18 enters the working position, and the main push assembly 22 pushes the second glass plate 5, causing the corresponding edge of the second glass plate 5 to simultaneously abut against the two upper reference rollers 204, completing the position and planar angle correction in one direction. The secondary reference assembly 19 then enters the working position, and the secondary push assembly 23 pushes the second glass plate 5, causing its other corresponding edge to abut against the upper reference roller 204, completing the position correction in the orthogonal direction.

[0037] Since the corresponding edges of the first glass plate 3 and the second glass plate 5 respectively abut against the lower reference roller 202 and the upper reference roller 204 in the same reference roller assembly 20, the two glass plates directly reference a common mechanical reference from their actual edges, thus establishing a corresponding relationship between their areas to be bonded. After the correction is completed, the support locking assembly 16 keeps the floating plate 12 in its current planar position. Then, the main push assembly 22, the secondary push assembly 23, the main reference assembly 18, and the secondary reference assembly 19 exit the pressing motion area of ​​the second glass plate 5. The lifting drive 8 then drives the locked second glass plate 5 to move along the pressing direction, so that the second glass plate 5 contacts the adhesive material on the spacer frame 4 and completes the pressing. The above-mentioned alignment process all occurs before the second glass plate 5 contacts the adhesive material, separating the position correction process from the subsequent bonding and pressing process.

[0038] As one embodiment of the present invention, refer to Figure 1 and Figure 4 The main reference assembly 18 includes a main reference guide rail 181, a main reference moving base 182, a main reference vertical back plate 183, and a main reference upper suspension beam 184. The main reference moving base 182 moves along the main reference guide rail 181 toward or away from the pressing area of ​​the first glass plate 3. The main reference vertical back plate 183 connects the main reference moving base 182 and the main reference upper suspension beam 184. Two reference roller assemblies 20 are spaced apart along one edge of the pressing area. The secondary reference assembly 19 includes a secondary reference guide rail 191, a secondary reference moving base 192, a secondary reference vertical back plate 193, and a secondary reference upper suspension arm 194. The moving base 192 moves toward or away from the area to be pressed along the secondary reference guide rail 191. The secondary reference vertical back plate 193 connects the secondary reference moving base 192 and the secondary reference upper suspension arm 194. A reference roller assembly 20 is disposed on the secondary reference upper suspension arm 194. The main reference guide rail 181 and the secondary reference guide rail 191 extend along the normal direction of the mutually orthogonal edge of the area to be pressed, so that the main reference assembly 18 defines the position and direction of one side of the area to be pressed at two points, and the secondary reference assembly 19 defines the orthogonal direction position at one point. Before the adhesive material contacts the second glass plate 5, a common bonding reference is established for the non-melting pressing of the first glass plate 3 and the second glass plate 5.

[0039] Specifically, the main reference moving base 182 carries the main reference vertical back plate 183 and the main reference upper suspension beam 184, which move as a whole along the main reference guide rail 181. Two reference roller assemblies 20 are respectively suspended on the side of the main reference upper suspension beam 184 near the glass plate, and are spaced apart along the same corresponding edge of the first glass plate 3 and the second glass plate 5, so that two mechanical references with a certain distance are formed between the two reference roller assemblies 20. The secondary reference moving base 192 carries the secondary reference vertical back plate 193 and the secondary reference upper suspension arm 194, which move along the secondary reference guide rail 191. One reference roller assembly 20 on the secondary reference upper suspension arm 194 is correspondingly arranged on the side adjacent to the main reference edge. The main reference guide rail 181 and the secondary reference guide rail 191 are orthogonal to each other, so the main reference assembly 18 and the secondary reference assembly 19 enter and exit the working position along the normal of the two adjacent glass edges, respectively. During alignment, the primary reference assembly 18 first reaches the working position, making the two upper reference rollers 204 form a two-point reference along one side. Under the action of the primary push-and-hold assembly 22, the second glass plate 5 simultaneously abuts against the two upper reference rollers 204, thus determining the position of that side and the planar rotation angle of the second glass plate 5. Based on this, the secondary reference assembly 19 enters the working position, using one upper reference roller 204 to limit the remaining translational position of the second glass plate 5 along the direction of the primary reference side. Thus, the three planar degrees of freedom of the second glass plate 5 are handled by two primary reference points and one secondary reference point, avoiding redundant constraints formed by simultaneous rigid clamping from all sides.

[0040] As one embodiment of the present invention, refer to Figure 4 The reference roller assembly 20 includes a fixed vertical shaft 201, a lower reference roller 202, a middle spacer 203, and an upper reference roller 204. The lower reference roller 202 and the upper reference roller 204 are independently rotatably mounted on the fixed vertical shaft 201. The middle spacer 203 is located between the lower reference roller 202 and the upper reference roller 204. Before the bonding material contacts the second glass plate 5, the lower reference roller 202 abuts against the edge of the first glass plate 3, and the upper reference roller 204 abuts against the corresponding edge of the second glass plate 5. The lower reference roller 202 and the upper reference roller 204 have the same outer diameter and their tangential positions facing the corresponding edges are located on the same vertical reference plane. The vertical reference plane constitutes a common bonding reference for the areas to be bonded of the first glass plate 3 and the second glass plate 5, so that the two areas to be bonded form a corresponding relationship before non-melting bonding.

[0041] Specifically, the fixed vertical shaft 201 is vertically mounted on the main reference upper suspension beam 184 and the secondary reference upper suspension arm 194. The lower reference roller 202 is located below the fixed vertical shaft 201 and corresponds to the edge height of the first glass plate 3. The upper reference roller 204 is located above the lower reference roller 202 and corresponds to the edge height of the second glass plate 5 when it is in the alignment position. The intermediate spacer sleeve 203 is disposed between the lower reference roller 202 and the upper reference roller 204 to maintain the axial spacing between the two rollers. The lower reference roller 202 and the upper reference roller 204 can rotate independently around the fixed vertical shaft 201, so that the first glass plate 3 and the second glass plate 5 will not be affected by the rotation of the rollers when they are respectively against the corresponding rollers. Since the lower reference roller 202 and the upper reference roller 204 are sleeved on the same fixed vertical shaft 201 and have the same outer diameter, the tangential positions of the two rollers toward the corresponding glass edge are consistent on the horizontal coordinate and form the same vertical reference plane in the vertical direction. When the first glass plate 3 is positioned, its actual edge is against the lower reference roller 202; when the second glass plate 5 is aligned, its corresponding actual edge is against the upper reference roller 204 set coaxially. Therefore, the second glass plate 5 is not indirectly positioned according to the preset coordinates of the suction cup assembly 13 or the floating plate 12, but is directly referenced by the same fixed vertical axis 201 as the first glass plate 3, thereby reducing the influence of the initial placement position of the second glass plate 5 and the suction cup adsorption position deviation on the correspondence between the two areas to be bonded.

[0042] As one embodiment of the present invention, refer to Figure 1 and Figure 4 It also includes a bottom mounting plate 1 and two sets of reference working limit components respectively corresponding to the main reference component 18 and the secondary reference component 19. The support plate 2, the main reference guide rail 181 and the secondary reference guide rail 191 are set on the bottom mounting plate 1. The bottom mounting plate 1 forms an integrated limit seat corresponding to the main reference component 18 and the secondary reference component 19 respectively. Each set of reference working limit components includes an adjustable limit screw 24, a rigid stop block 25 and a locking nut for locking the adjustable limit screw 24, which are installed on the corresponding integrated limit seat. The rigid stop blocks 25 of the two sets of reference working limit components are fixed to the main reference moving base 182 and the secondary reference moving base 192 respectively, and abut against the corresponding adjustable limit screw 24 when the corresponding reference component enters the working position.

[0043] Specifically, the bottom mounting plate 1 forms a common mounting base for the support plate 2, the main reference component 18, and the secondary reference component 19. The integrated limiting seats corresponding to the main reference component 18 and the secondary reference component 19 are respectively located on one side of their respective movement directions. Adjustable limiting screws 24 are mounted on the integrated limiting seats along the movement direction of the corresponding reference component. Their extended positions are adjustable and are held in place by locking nuts after adjustment. Rigid stop blocks 25 are fixed to the corresponding main reference moving base 182 or secondary reference moving base 192 and move synchronously with the moving base. When the main reference component 18 or the secondary reference component 19 enters the area to be pressed, the rigid stop block 25 finally abuts against the contact end of the adjustable limiting screw 24, thereby limiting the working position of the corresponding reference component through a rigid contact relationship. The working position of the reference roller assembly 20 can be initially calibrated by adjusting the adjustable limit screw 24. After calibration, the position is maintained by the locking nut, so that the final working position of the reference roller assembly 20 is mainly determined by the mechanical stop relationship, rather than solely by the stopping position of the drive component itself. After the glass plate is calibrated and locked, each reference component moves in the opposite direction, causing the reference roller assembly 20 to leave the subsequent pressing motion area of ​​the second glass plate 5.

[0044] As one embodiment of the present invention, refer to Figure 8 and Figure 9 The support locking assembly 16 is configured in three sets and arranged in a triangular pattern. The support locking assembly 16 supports the floating plate 12, and the locking drive assembly 17 switches the floating plate 12 between floating and locked states. Each support locking assembly 16 includes a fixed sleeve 161 fixed to the lower support plate 11, a lifting support 162 sliding along the axial direction of the fixed sleeve 161, a universal ball bearing 163 disposed on the top of the lifting support 162, a lower limit cover 165 fixed to the lower end of the fixed sleeve 161, a support spring 164 abutting between the lifting support 162 and the lower limit cover 165, and an annular friction pad 166 disposed on the lower support plate 11 and surrounding the fixed sleeve 161. Under the action of the support spring 164, the universal ball bearing 163 extends above the annular friction pad 166 and supports the floating plate 12. When the floating plate 12 is pressed down, it pushes the universal ball bearing 163 and the lifting support 162 down and into contact with the annular friction pad 166.

[0045] Specifically, three sets of support locking assemblies 16 are distributed below the floating plate 12 to form a three-point support. The fixed sleeve 161 is fixed to the lower bearing plate 11. The lifting support 162 is located inside the fixed sleeve 161 and can slide a small range vertically relative to the fixed sleeve 161. The support spring 164 is located between the lifting support 162 and the lower limit cover 165 and continuously acts upward on the lifting support 162. The universal ball bearing 163 is located on the top of the lifting support 162 and can roll freely. The annular friction pad 166 is located around the fixed sleeve 161, and its friction support surface is lower than the highest support position of the universal ball bearing 163 in the free state. In the free state, the highest support position of the universal ball bearing 163 is higher than the annular friction pad 166, so that the floating plate 12 is supported by the three universal balls bearing 163 and separated from the annular friction pad 166. The floating plate 12 can perform limited planar translation and slight rotation relative to the lower bearing plate 11 under the rolling support of the universal balls bearing 163. When the locking drive assembly 17 applies pressure to the floating plate 12 from above, the floating plate 12 pushes the universal ball 163 and the lifting support 162 to overcome the elastic force of the support spring 164 and retract downward until the lower surface of the floating plate 12 contacts the three annular friction pads 166. At this time, the floating plate 12 changes from a low-resistance rolling support state to a frictional contact state, providing frictional constraint to maintain the already corrected planar position.

[0046] As one embodiment of the present invention, refer to Figure 2 , Figure 3 and Figure 7 The locking drive assembly 17 includes a compact guide cylinder 171, a triangular pressure plate 172, three threaded adjusting rods 173, and three flat pressure plates 174. The fixed cylinder body of the compact guide cylinder 171 is installed on the lifting connecting plate 9. The movable worktable of the compact guide cylinder 171 is fixedly connected to the triangular pressure plate 172. The three threaded adjusting rods 173 are respectively set at the three apex corners of the triangular pressure plate 172. Each threaded adjusting rod 173 has a flat pressure plate 174 at its lower end. The three flat pressure plates 174 are coaxial with the three sets of support locking assemblies 16 and are used to apply pressure synchronously from above the floating plate 12 to press the floating plate 12 tightly against the three annular friction pads 166.

[0047] Specifically, the fixed cylinder body of the compact guide cylinder 171 is fixed to the lifting connecting plate 9 and rises and falls as a whole with the lifting connecting plate 9. Its movable worktable can move vertically relative to the fixed cylinder body. The triangular pressure plate 172 is connected below the movable worktable and rises and falls synchronously with the movable worktable. Three threaded adjusting rods 173 are respectively provided for three sets of support locking assemblies 16. The threaded adjusting rods 173 can adjust the vertical position of the corresponding flat pressure plate 174 so that the three flat pressure plates 174 basically contact the floating plate 12 synchronously during the locking action. In the free alignment state, a gap is maintained between the three planar pressure plates 174 and the upper surface of the floating plate 12, without restricting the planar adjustment of the floating plate 12. When locking is required, the compact guide cylinder 171 drives the movable worktable to move downwards, and the three planar pressure plates 174 descend synchronously via the triangular pressure plate 172 and the three threaded adjusting rods 173. After the planar pressure plates 174 contact the floating plate 12, they continue to apply vertical pressure, causing the three universal ball bearings 163 and the lifting support 162 to retract synchronously, and the floating plate 12 presses against the three annular friction pads 166. This forms a three-point friction locking structure with pressure applied from above by the three planar pressure plates 174 and support from below by the three annular friction pads 166. The locking force is mainly applied in the vertical direction to reduce lateral disturbance to the already completed planar alignment position of the second glass plate 5 during the locking process. This locking action is only used to maintain the already formed alignment position and does not serve to reposition the second glass plate 5.

[0048] As one embodiment of the present invention, refer to Figure 5 , Figure 6 and Figure 9 It also includes three large-head limiting posts 15 fixed to the lower support plate 11. The light rod of each large-head limiting post 15 passes through the corresponding enlarged circular hole 121 on the floating plate 12. A radial gap is maintained between the light rod and the hole wall of the corresponding enlarged circular hole 121. The limiting head of the large-head limiting post 15 is located above the floating plate 12 to prevent the floating plate 12 from detaching upward. The floating plate 12 is provided with a suction cup mounting hole. The lower support plate 11 is provided with a suction cup clearance hole 111 corresponding to the suction cup mounting hole. Each suction cup assembly 13 includes a hollow connecting sleeve 131 that passes through and is fixed to the suction cup mounting hole and a flexible suction cup 132 disposed at the lower end of the hollow connecting sleeve 131. The hollow connecting sleeve 131 passes through the corresponding suction cup clearance hole 111.

[0049] Specifically, three large-end limiting posts 15 are fixed at intervals to the lower support plate 11 and pass upward through the floating plate 12. The diameter of the enlarged circular hole 121 is larger than the diameter of the smooth rod of the large-end limiting post 15, so that when the floating plate 12 is in the normal alignment range, a gap is maintained between the smooth rod of the large-end limiting post 15 and the wall of the enlarged circular hole 121, so as not to provide rigid guidance for the planar translation and slight rotation of the floating plate 12. The limiting head at the upper end of the large-end limiting post 15 is located above the floating plate 12, and forms an axial limit with the floating plate 12 when the floating plate 12 shows an upward tendency to detach, thereby preventing the floating plate 12 from detaching from the lower support plate 11 while retaining the planar floating degree of freedom. The suction cup assembly 13 is distributed on the floating plate 12. The hollow connecting sleeve 131 is fixed to the floating plate 12 and passes downward through the suction cup clearance hole 111 of the lower support plate 11. The size of the suction cup clearance hole 111 can provide clearance space for the limited planar displacement of the hollow connecting sleeve 131 with the floating plate 12. The flexible suction cup 132 is located at the lower end of the hollow connecting sleeve 131 and adsorbs the non-adhesive surface of the second glass plate 5. Therefore, during the alignment process, the second glass plate 5, the flexible suction cup 132, the hollow connecting sleeve 131 and the floating plate 12 remain as a single moving whole. The position adjustment is achieved by the overall floating of the floating plate 12 relative to the lower bearing plate 11, without the need for the flexible suction cup 132 to slide laterally on the surface of the second glass plate 5.

[0050] As one embodiment of the present invention, refer to Figure 1 , Figure 10 and Figure 11 Both the main push-back assembly 22 and the secondary push-back assembly 23 are composed of a standard push-back module 21. The standard push-back module 21 includes a push-back guide rail 211, a push-back movable base 212, a side-mounted compact cylinder 213, a square-hole guide seat 214, a combined push rod, a compression spring 217, a lateral limiting pin 219, a roller fork 220, and push-back rollers 221. The push-back movable base 212 moves along the push-back guide rail 211, and the side-mounted compact cylinder 213 drives the push-back movable base 212. The square-hole guide seat 214 is fixed to the push-back movable base 212. The combined push rod includes an integrally connected square anti-rotation guide section 215 and a cylindrical spring tail rod 216. The square anti-rotation guide section 215... The cylindrical spring tail rod 216 is slidably disposed within the square hole guide seat 214, passing through the rear end spring seat wall of the square hole guide seat 214. The compression spring 217 is sleeved on the cylindrical spring tail rod 216, with both ends abutting against the shoulder between the square anti-rotation guide section 215 and the cylindrical spring tail rod 216 and the rear end spring seat wall, respectively. The square hole guide seat 214 is provided with an elongated oval limiting hole 218, and the transverse limiting pin 219 passes through the elongated oval limiting hole 218 and is fixed to the square anti-rotation guide section 215 to limit the maximum retraction of the combined push rod relative to the square hole guide seat 214. The roller fork 220 is connected to the front end of the square anti-rotation guide section 215, and the push roller 221 is rotatably disposed on the roller fork 220.

[0051] Specifically, the main push-back assembly 22 and the secondary push-back assembly 23 adopt the same standard push-back module 21 and are arranged in mutually orthogonal directions. The output motion of the side-mounted compact cylinder 213 first acts on the push-back moving base 212, causing the push-back moving base 212 together with the square hole guide seat 214 to move along the push-back guide rail 211 toward the second glass plate 5. The side-mounted compact cylinder 213 is not directly rigidly connected to the combined push rod. The square anti-rotation guide section 215 forms an axial sliding fit with the square hole guide seat 214, allowing the combined push rod to retract relative to the square hole guide seat 214 in the push-back direction, while restricting the combined push rod from rotating around its own axis. The cylindrical spring tail rod 216 passes through the rear end spring seat wall and maintains axial sliding, and the compression spring 217 is located between the shoulder of the combined push rod and the rear end spring seat wall. When the push roller 221 has not yet contacted the second glass plate 5, the combined push rod moves forward together with the square hole guide seat 214. When the push roller 221 contacts the second glass plate 5 and is blocked, the push moving base 212 and the square hole guide seat 214 continue to move forward, causing the combined push rod to retract backward relative to the square hole guide seat 214 and compress the compression spring 217. This converts part of the overstroke of the actuator into elastic compression, allowing the push roller 221 to maintain the second glass plate 5 against the corresponding reference with elastic force. The lateral limit pin 219 moves within the elongated limit hole 218 along with the square anti-rotation guide section 215. When the lateral limit pin 219 reaches the end of the elongated limit hole 218, it forms a maximum retraction limit, preventing the combined push rod from continuing to retract. The push roller 221 can rotate within the roller fork 220. Therefore, when the main push assembly 22 pushes the second glass plate 5 towards the two upper main reference rollers 204, the second glass plate 5 can translate and rotate slightly in a floating state. After completing the main direction and angle alignment, the secondary push assembly 23 acts in the orthogonal direction, causing the second glass plate 5 to move along the two upper main reference rollers 204 that have been attached, until the other edge contacts the upper reference roller 204 of the secondary reference assembly 19, thereby completing the planar position correction in sequence.

[0052] As one embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 3It also includes a gantry frame 6, a vertical lifting guide assembly 7, and four fixed-length support sleeves 10. The lifting drive component 8 is a central servo electric cylinder. The gantry frame 6 includes a left column 61, a right column 62, and a top crossbeam 63 connecting the left column 61 and the right column 62. The vertical lifting guide assembly 7 includes two vertical linear guide rails 71 respectively set on the left column 61 and the right column 62, two lifting sliders 72 set on each vertical linear guide rail 71, and two lifting connecting side plates 73 respectively connecting the two lifting sliders 72 on the same side to the lifting connecting plate 9. The lifting drive component 8 is installed on the top crossbeam 63 and its output end is connected to the lifting connecting plate 9. The lifting connecting plate 9 is connected to the lower bearing plate 11 through four fixed-length support sleeves 10.

[0053] Specifically, the left column 61 and right column 62 are respectively located on both sides of the working area. The top beam 63 spans the upper ends of the left column 61 and right column 62. The lifting drive component 8 is located in the middle of the top beam 63, and its output end is connected to the lifting connecting plate 9 in the vertical direction. Two vertical linear guide rails 71 are respectively located on opposite sides of the left column 61 and right column 62. Two lifting sliders 72 on each vertical linear guide rail 71 are spaced apart in the vertical direction. The two lifting sliders 72 on the same side are connected to the lifting connecting plate 9 through the corresponding lifting connecting side plate 73, forming four vertical guides from both sides of the lifting connecting plate 9. When the lifting drive component 8 extends or retracts, the lifting connecting plate 9 moves in the vertical direction under the constraint of the vertical lifting guide component 7, and synchronously drives the lower bearing plate 11 to move through the four fixed-length support sleeves 10, so that the support locking component 16 installed on the lower bearing plate 11, as well as the floating plate 12, suction cup component 13, and second glass plate 5 supported or locked by it, are lifted as a whole. Four fixed-length support sleeves 10 simultaneously maintain a fixed distance between the lifting connecting plate 9 and the lower bearing plate 11, and transmit the vertical force generated by the lifting drive component 8 to the lower bearing plate 11 when the second glass plate 5 is pressed together. The vertical lifting guide assembly 7 restricts the lateral movement and tilting of the lifting connecting plate 9, so that after the second glass plate 5 completes plane correction and locks, it mainly moves along the pressing direction.

[0054] As one embodiment of the present invention, refer to Figure 12 The support plate 2 is provided with a shallow negative pressure cavity 26, an annular sealing groove 27 surrounding the shallow negative pressure cavity 26, and a lateral vacuum interface communicating with the shallow negative pressure cavity 26. The shallow negative pressure cavity 26 is used to maintain the position of the first glass plate 3 under negative pressure after the first glass plate 3 is positioned by the lower reference roller 202. The floating plate 12 is provided with a vacuum distribution block 14. The vacuum distribution block 14 has a main interface and four branch interfaces, and each branch interface is respectively connected to a suction cup assembly 13.

[0055] Specifically, a shallow negative pressure chamber 26 is located on the side of the support plate 2 facing the first glass plate 3 and within the coverage area of ​​the first glass plate 3. An annular sealing groove 27 surrounds the shallow negative pressure chamber 26, and a conventional seal within the annular sealing groove 27 can form a relatively closed negative pressure area together with the lower surface of the first glass plate 3. A lateral vacuum interface communicates with the shallow negative pressure chamber 26 through an internal channel of the support plate 2 and is connected to an external negative pressure source. When the actual edge of the first glass plate 3 is abutting against the lower reference rollers 202 at the two main reference positions and one lower reference roller 202 at the secondary reference position, negative pressure is extracted from the shallow negative pressure chamber 26, causing the first glass plate 3 to be held towards the support plate 2. Thus, after the main reference assembly 18 and the secondary reference assembly 19 are withdrawn, the position determined by the three lower reference rollers 202 continues to be maintained. The shallow negative pressure chamber 26 mainly undertakes the vertical adsorption and holding function, without using negative pressure to readjust the planar position of the first glass plate 3. The vacuum distribution block 14 is mounted on the floating plate 12 and moves with it. Its main interface is connected to an external negative pressure source via a flexible pipeline, and its four branch interfaces are connected to the hollow connecting sleeves 131 of the four suction cup assemblies 13, allowing the four flexible suction cups 132 to jointly adsorb the second glass plate 5. The flexible pipeline connected to the vacuum distribution block 14 retains a slack margin to accommodate the limited planar displacement and rotation of the floating plate 12, thereby reducing the pulling effect of the pipeline on the alignment movement of the floating plate 12. The negative pressure holding circuit corresponding to the first glass plate 3 and the suction cup negative pressure circuit corresponding to the second glass plate 5 can be controlled separately, so that when the second glass plate 5 is adsorbed, aligned, pressed, or de-adsorbed, the first glass plate 3 can still be maintained in a predetermined reference position according to the working process.

[0056] Working principle: During operation, the first glass plate 3 is placed on the support plate 2, and its pressing area is pre-equipped with a spacer frame 4 to support the adhesive material. The main reference assembly 18 and the secondary reference assembly 19 first enter the working position, so that one edge of the first glass plate 3 simultaneously contacts two lower reference rollers 202, and the adjacent edge contacts another lower reference roller 202. The planar position of the first glass plate 3 is determined by the two main reference points and one secondary reference point. After positioning, the first glass plate 3 is held under negative pressure by the shallow negative pressure cavity 26 of the support plate 2, and then the main reference assembly 18 and the secondary reference assembly 19 are withdrawn to reserve space for the second glass plate 5 to descend.

[0057] The second glass plate 5 is held in place by the suction cup assembly 13 on the floating plate 12 from the non-adhesive surface and is lowered by the lifting drive 8. During the descent, the floating plate 12 remains locked to prevent the second glass plate 5 from undergoing unexpected planar movement. When the second glass plate 5 descends above the spacer frame 4 and has not yet contacted the adhesive material, the locking drive assembly 17 releases its lock, and the support spring 164 pushes the lifting support 162 and the universal ball bearings 163 upward, causing the floating plate 12 to disengage from the annular friction pad 166 and be supported by the three universal ball bearings 163. At this time, the floating plate 12 can perform limited planar translation and rotation relative to the lower support plate 11. The second glass plate 5, the suction cup assembly 13, and the floating plate 12 are adjusted in position as a whole, while the suction cup itself does not slide on the surface of the second glass plate 5.

[0058] The main reference assembly 18 then re-enters the working position. The lower reference roller 202 and upper reference roller 204 in each reference roller assembly 20 are coaxially arranged and have the same outer diameter, so their tangential positions toward the glass edge are on the same vertical reference plane. The first glass plate 3 was previously positioned by the lower reference roller 202, while the second glass plate 5 is corrected by the corresponding upper reference roller 204. This allows the two glass plates to directly reference the same mechanical bonding reference, rather than indirectly determining whether the glass plates are aligned using the theoretical position of the suction cup or floating plate 12.

[0059] After the main reference assembly 18 is in place, the main push-abutment assembly 22 elastically pushes the second glass plate 5 from the opposite side. Supported by the universal ball bearings 163, the second glass plate 5 undergoes translation and slight rotation until its corresponding edges simultaneously abut against the two upper reference rollers 204, thus completing positional correction in one direction and planar rotational correction. Then, the secondary reference assembly 19 enters the working position, and the secondary push-abutment assembly 23 pushes the second glass plate 5 again in a direction orthogonal to the main reference direction, causing the second glass plate 5 to adjust along the two upper main reference rollers 204 until adjacent edges contact the upper reference rollers 204 of the secondary reference assembly 19. Thus, by using "two main references + one secondary reference," the two translational degrees of freedom and one planar rotational degree of freedom of the second glass plate 5 are sequentially defined, creating a corresponding relationship between the areas to be bonded of the two glass plates.

[0060] Both the main push-fit assembly 22 and the secondary push-fit assembly 23 employ an elastic push-fit method. A side-mounted compact cylinder 213 drives the push-fit moving base 212 forward. When the push-fit roller 221 contacts the second glass plate 5, the combined push rod retracts relative to the square hole guide seat 214 and compresses the compression spring 217, converting the remaining stroke of the actuator into an elastic overstroke. The square anti-rotation guide section 215 ensures that the push rod only moves along the push-fit direction, and the lateral limiting pin 219 cooperates with the elongated limiting hole 218 to limit the maximum retraction. Therefore, the push-fit assembly can maintain the second glass plate 5 against the reference, while reducing the impact of rigid pressure and actuator stop position errors on the alignment process.

[0061] After the second glass plate 5 is aligned, the locking drive assembly 17 drives the three planar pressure plates 174 to simultaneously press the floating plate 12 downwards, causing the universal ball bearings 163 and the lifting support 162 to retract downwards. The floating plate 12 then presses against the three annular friction pads 166. The floating plate 12 switches from a low-resistance rolling support state to a friction locking state, thus maintaining the aligned planar position. This locking process is only used to save the alignment results and does not reposition the second glass plate 5.

[0062] After locking is completed, the secondary push-adhesion component 23, the primary push-adhesion component 22, the secondary reference component 19, and the primary reference component 18 exit the descending area of ​​the glass plate. Since the floating plate 12 has been locked, the second glass plate 5 remains in the corrected position after these edge constraints are released. Finally, the lifting drive component 8 drives the lower support plate 11, the floating plate 12, the suction cup component 13, and the second glass plate 5 to descend vertically as a whole, so that the bonding surface of the second glass plate 5 contacts the bonding material carried by the spacer frame 4 and completes the pressing. In this way, the present invention performs glass plate alignment, position locking, edge mechanism withdrawal, and bonding pressing in sequence, so that all plane correction is completed before the second glass plate 5 contacts the bonding material. During the pressing stage, only the established common mechanical reference is kept moving in the vertical direction, thereby reducing the influence of suction cup adsorption position and mechanism movement errors on the actual bonding position correspondence of the two glass plates.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
