Description

Technical Field

[0001] This invention belongs to the field of adhesive application equipment technology, specifically an adhesive application device for panels and a panel adhesive application production method. Background Technology

[0002] Panel gluing equipment is widely used in modern furniture manufacturing, building decoration and automotive interior industries. As people's requirements for product quality continue to increase, the accuracy and efficiency of panel installation gluing process have become key factors affecting product quality.

[0003] However, existing panel gluing equipment still has significant drawbacks. First, its positioning effect is unsatisfactory; panels are prone to shifting during installation and cannot maintain a stable position. This not only affects the accuracy of the gluing operation but may also lead to uneven glue distribution, impacting the quality of the final product. Second, existing equipment typically requires multiple independent clamping devices to press the panel firmly to ensure full adhesion between the panel and the glue. This design not only increases the complexity and manufacturing cost of the equipment but also makes the operation cumbersome, reducing production efficiency. Furthermore, the coordinated operation of multiple clamping devices increases the risk of equipment failure and hinders maintenance and upkeep. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a panel gluing device and a panel gluing production method. This invention primarily addresses the core defects of existing panel gluing devices, such as insufficient positioning accuracy and reliance on multiple clamping mechanisms.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a panel gluing device, including a worktable, a panel frame, and a six-axis gluing robot. The upper part of the panel frame is provided with a mounting groove for installing glass panels. The upper part of the worktable is provided with four support columns arranged in a matrix to support the panel frame. The upper part of the worktable is provided with a feeding and pressing mechanism for feeding glass panels on one side of the panel frame. The upper part of the worktable is provided with long side positioning mechanisms on the two long side plates near the inside of the panel frame, and short side positioning mechanisms are provided on the two short side plates near the inside of the panel frame.

[0006] The long-side positioning mechanism includes two long-side positioning hydraulic cylinders that are tilted upwards and hinged to the upper part of the worktable near the inner long-side side plate of the panel frame. A long-side positioning strip for positioning the inner corner of the inner long-side side plate of the panel frame is connected between the output shafts of the two long-side positioning hydraulic cylinders. The upper surface of the long-side positioning strip is in contact with the upper surface of the inner wall of the panel frame.

[0007] The short side positioning mechanism includes a short side positioning hydraulic cylinder installed on the upper part of the workbench near the short side plate inside the panel frame. The output shaft of the short side positioning hydraulic cylinder is connected to a short side positioning plate for positioning the short side plate inside the panel frame. The upper surface of the short side positioning plate is in contact with the upper surface of the inner wall of the panel frame.

[0008] Preferably, each of the long-side positioning hydraulic cylinders and each of the short-side positioning hydraulic cylinders is equipped with a pressure control valve. The pressure control valve controls each of the long-side positioning hydraulic cylinders and each of the short-side positioning hydraulic cylinders to work synchronously and provides low pressure during the pre-clamping stage to allow the panel frame to slide relative to each other during the clamping process, preventing the initial clamping from interfering with the subsequent clamping.

[0009] Preferably, the long side positioning mechanism is inclined; the shape of the side of the long side positioning strip away from the output shaft of the long side positioning hydraulic cylinder is adapted to the inner corner of the long side plate of the panel frame to achieve precise fit.

[0010] Preferably, the long side positioning mechanism further includes an angle adjustment component for adjusting the tilt of the long side positioning hydraulic cylinder. The angle adjustment component includes a limiting sleeve disposed on two long side positioning hydraulic cylinders on the same side, a connecting rod connected between the two limiting sleeves, and a connecting rod hinged to the outside of the connecting rod. The angle adjustment component also includes a bolt rod that is screwed through the bottom of the worktable surface by a thread. A hinge seat is rotatably disposed at the upper end of the bolt rod, and the other end of the connecting rod is hinged to the hinge seat.

[0011] Preferably, the long-side positioning strip is made of Teflon.

[0012] Preferably, the feeding and pressing mechanism includes two limiting seats disposed on the upper part of the worktable. A limiting rod is rotatably disposed between the opposite ends of the two limiting seats. Arc-shaped plates are fixedly disposed on the outer sides of both ends of the limiting rod. A base plate is disposed between the other ends of the two arc-shaped plates. A pressing frame is disposed on the upper part of the base plate. Four adsorption components corresponding to each support column are arranged in a matrix within the pressing frame on the upper part of the base plate. A bent handle is disposed at each of the two corners on the side of the base plate away from the arc-shaped plates. A grip is connected between the two bent handles.

[0013] Preferably, the central axis of the limiting rod is flush with the mounting groove on the upper part of the panel frame. A long side baffle is provided on the upper part of the worktable near the long side of the pressing frame, and a short side baffle is provided near the short side of the pressing frame. After the long side and short side of the glass panel are respectively attached to the long side baffle and the short side baffle, when the base plate is rotated clockwise, the panel adsorbed on the adsorption component can be accurately attached to the mounting groove on the panel frame.

[0014] Preferably, the adsorption assembly includes a guide tube, which is fixed to the base plate and has a tube body that slides longitudinally through it. A suction cup is connected to the upper end of the tube body, and the glass panel is adsorbed onto the suction cup by a vacuum pump. The upper side of the pressing frame is higher than the upper end of the tube body but lower than the upper side of the suction cup. A flange is provided at the outer edge of the upper end of the tube body, and a limiting spring is sleeved on the outside of the tube body between the flange and the guide tube. The two ends of the limiting spring are respectively connected to the bottom of the flange and the upper end of the guide tube.

[0015] Preferably, the feeding and pressing mechanism further includes a limiting mechanism to prevent the bottom plate from rotating counterclockwise. The limiting mechanism includes a protrusion at one end of one of the handles, a grip hinged to the bottom of the handle, a ratchet and ratchet teeth rotatably disposed on one side of the limiting seat corresponding to the handle, and a limiting block fixedly installed on one side of the limiting seat. One end of the ratchet is connected to the limiting rod. The limiting block and the ratchet teeth are connected by a return spring, so that when the return spring is in the reset state, one end of the ratchet teeth is engaged with the ratchet, so that the ratchet can only rotate clockwise in one direction. An outer tube is connected through the protrusion and the limiting block, and an inner wire is disposed through the outer tube. The two ends of the inner wire are respectively connected to the grip and the ratchet teeth.

[0016] A panel adhesive application production method includes applying adhesive to the panel using panel adhesive application equipment, as detailed below: S1. Place the panel frame on the support column on the workbench to support the panel frame; S2. The six-axis glue-applying robot applies glue to the glass panel mounting slots on the panel frame. S3. Use a vacuum pump to attach the glass panel to the suction cup, then flip the base plate to press the glass panel firmly against the mounting groove on the panel frame. S4. After the glue solidifies, release the glass panel from the adhesive process. Then, release the counterclockwise rotation limit of the base plate by adjusting the limiting mechanism, so that the base plate rotates counterclockwise back to the initial position and feeds the next glass panel.

[0017] The beneficial effects of this invention are as follows: 1. This invention achieves comprehensive stable support and precise positioning of the panel frame through the coordinated operation of support columns, a long-side positioning mechanism, and a short-side positioning mechanism. Four support columns provide stable support to the bottom of the panel frame, while the long-side and short-side positioning hydraulic cylinders work synchronously to clamp and position the panel frame from the long and wide side plates respectively, forming a stable positioning system. This design ensures that the panel frame will not shift during installation and glue application, greatly improving processing accuracy and product quality, and avoiding problems such as uneven glue application or improper panel installation caused by panel frame movement.

[0018] 2. This invention achieves precise adjustment of the angle of the long-side positioning hydraulic cylinder through the precise cooperation of the bolt rod, connecting rod, linking rod, and long-side positioning hydraulic cylinder. By rotating the bolt rod to generate longitudinal displacement, it drives the connecting rod and linking rod on the hinge seat to move, allowing the long-side positioning hydraulic cylinder to adjust its angle according to actual needs. This design enables the long-side positioning strip to be precisely aligned with the inner corner of the long side panel of the panel frame, achieving a more accurate positioning effect and enhancing the overall stability of the panel frame. This precise adjustment mechanism ensures that the panel maintains its optimal condition during the glue application process, effectively preventing panel deformation or installation quality problems caused by inaccurate positioning.

[0019] 3. This invention utilizes a six-axis robot for precise glue application, evenly spreading the glue onto the mounting slots on the upper part of the panel frame; the adsorption component firmly adheres to the glass panel using suction cups, ensuring the panel does not move during loading; and the flipping mechanism enables a smooth transfer of the panel from the loading position to the mounting position. This design significantly improves production efficiency, enhances the stability and consistency of the production line, and makes the entire processing more efficient and precise.

[0020] 4. This invention achieves continuous clamping of the clamping frame through a mechanical locking mechanism composed of ratchet teeth and a ratchet wheel. After the clamping frame presses the panel firmly, the ratchet teeth engage with the ratchet wheel, allowing only clockwise rotation and preventing counter-clockwise rotation. This ensures that the clamping frame does not detach from the panel after the handle is released, maintaining a continuous clamping state. This design guarantees full adhesion between the panel and the adhesive, preventing the adhesive from shifting or forming air bubbles during curing due to external forces, significantly improving bonding quality. Once the adhesive has completely solidified, squeezing the handle disengages the ratchet teeth from the ratchet wheel, easily releasing the clamping frame and returning the mechanism to its initial position, preparing for the loading of the next panel and achieving an efficient and continuous production cycle.

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 3 As shown, a panel gluing device includes a worktable 1, a panel frame 2, and a six-axis gluing robot 3. The upper part of the panel frame 2 is provided with a mounting groove for mounting glass panels. The upper part of the worktable 1 is provided with four support columns 9 arranged in a matrix to support the panel frame 2. The upper part of the worktable 1 is provided with a feeding and pressing mechanism 4 for feeding glass panels on one side of the panel frame 2. Long side positioning mechanisms are installed on the two long side plates of the upper part of the worktable 1 near the inside of the panel frame 2, and short side positioning mechanisms are installed on the two short side plates near the inside of the panel frame 2.

[0026] like Figure 2 As shown, the long side positioning mechanism includes two long side positioning hydraulic cylinders 5 that are inclined upward and hinged to the upper part of the worktable 1 near the inner long side plate of the panel frame 2. A long side positioning strip 6 for positioning the inner corner of the inner long side plate of the panel frame 2 is connected between the output shafts of the two long side positioning hydraulic cylinders 5. The upper surface of the long side positioning strip 6 is in contact with the upper surface of the inner wall of the panel frame 2, thereby providing precise support for the glued position on the panel frame 2.

[0027] like Figure 2 As shown, the short side positioning mechanism includes a short side positioning hydraulic cylinder 7 installed on the upper part of the workbench 1 near the short side plate inside the panel frame 2. The output shaft of the short side positioning hydraulic cylinder 7 is connected to a short side positioning plate 8 for positioning the short side plate inside the panel frame 2. The upper surface of the short side positioning plate 8 is in contact with the upper surface of the inner wall of the panel frame 2, thereby providing precise support for the glued position on the panel frame 2.

[0028] like Figure 2 As shown, each long-side positioning hydraulic cylinder 5 and each short-side positioning hydraulic cylinder 7 is equipped with a pressure control valve. The pressure control valve controls each long-side positioning hydraulic cylinder 5 and each short-side positioning hydraulic cylinder 7 to work synchronously and provides low pressure during the pre-clamping stage to allow the panel frame 2 to slide relative to each other during the clamping process, preventing the initial clamping from interfering with the subsequent clamping. After the long-side positioning strip 6 and the short-side positioning plate 8 have both contacted the inner wall of the panel frame 2, the pressure control valve is adjusted to the normal pressure, thereby realizing the positioning and clamping of the panel frame 2.

[0029] In this scheme, during operation, the panel frame 2 is placed on the upper end of the support columns 9 on the workbench 1. The four support columns 9 support the bottom of the panel frame 2. Then, the pressure control valve adjusts the long side positioning hydraulic cylinder 5 of the long side positioning mechanism and the short side positioning hydraulic cylinder 7 of the short side positioning mechanism to a low pressure state in the pre-clamping stage. This controls the long side positioning hydraulic cylinder 5 and the short side positioning hydraulic cylinder 7 to act synchronously, so that the short side positioning plate 8 of the output shaft of the short side positioning hydraulic cylinder 7 clamps and positions the wide side plate of the panel frame 2, while the long side positioning plate of the output shaft of the long side positioning hydraulic cylinder 5... Positioning bar 6 clamps and positions the long side plate of panel frame 2. Finally, both the long side positioning bar 6 and the short side positioning plate 8 contact the inner wall of panel frame 2. Then, the control pressure valve is adjusted to normal pressure to achieve positioning and clamping of panel frame 2. By first pre-clamping with low pressure and then positioning and clamping with high pressure, the interference problem caused by the first clamping can be effectively avoided, thereby improving the positioning accuracy of panel frame 2. At the same time, sufficient clamping force can be provided during final positioning to ensure the stability of panel frame 2 during glue application and glass panel installation.

[0030] After positioning and clamping, the six-axis glue-applying robot 3 applies glue to the surface of the mounting groove on the upper part of the panel frame 2 for installing the glass panel. Then, the glass panel is placed in the mounting groove and pressed by the feeding and pressing mechanism 4 to ensure that the glass panel and the glue in the mounting groove are in full contact and tightly bonded. This prevents gaps or air bubbles from appearing due to the panel loosening during the glue solidification process, thus completing the automatic glue application and bonding of the panel.

[0031] Furthermore, such as Figure 6As shown, the long-side positioning mechanism is tilted; the shape of the side of the long-side positioning strip 6 away from the output shaft of the long-side positioning hydraulic cylinder 5 is adapted to the inner corner of the long-side side plate of the panel frame 2, achieving precise fitting. By tilting the long-side positioning mechanism and adapting the shape of the side of the long-side positioning strip 6 away from the output shaft of the long-side positioning hydraulic cylinder 5 to the inner corner of the long-side side plate of the panel frame 2, the support and positioning accuracy are ensured by avoiding the closing edge of the long-side side plate of the panel frame 2, thus ensuring the accuracy of subsequent panel gluing.

[0032] like Figure 1 and Figures 4 to 5 As shown, the long side positioning mechanism also includes an angle adjustment assembly for adjusting the tilt of the long side positioning hydraulic cylinder 5. The angle adjustment assembly includes a limiting sleeve 51 disposed on two long side positioning hydraulic cylinders 5 on the same side. A connecting rod 52 is connected between the two limiting sleeves 51. A connecting rod 53 is hinged to the outside of the connecting rod 52. The angle adjustment assembly also includes a bolt rod 54 that is screwed through the bottom of the worktable 1. A hinge seat 55 is rotatably disposed at the upper end of the bolt rod 54. The other end of the connecting rod 53 is hinged to the hinge seat 55.

[0033] In this scheme, during use, by rotating the bolt rod 54 to make its longitudinal displacement, the bolt rod 54 will cause the connecting rod 53 on the hinge seat 55 to drive the long side positioning hydraulic cylinders 5 at both ends of the connecting rod 52 to rotate. Adjusting the angle of the long side positioning hydraulic cylinder 5, so that the long side positioning strip 6 of the output shaft of the long side positioning hydraulic cylinder 5 corresponds to the inner corner position of the long side plate of the panel frame 2, and then the long side positioning hydraulic cylinder 5 causes the long side positioning strip 6 to clamp and position the inner corner position of the long side plate of the panel frame 2, ensuring the accuracy and stability of the panel frame 2, thereby improving the positioning accuracy of the panel frame 2, and thus improving the accuracy of panel glue application.

[0034] Furthermore, such as Figure 6 As shown, the long-side positioning strip 6 is made of Teflon, a non-stick material. Therefore, during the low-pressure pre-clamping stage controlled by the pressure sensor, if the long-side positioning mechanism and the short-side positioning mechanism are not synchronized, clamping can proceed from one direction to the other. The smooth surface of the Teflon material allows the panel frame 2 to be easily pushed, ensuring that the long-side positioning strip 6 and the short-side positioning plate 8 are precisely clamped onto the inner corner of the long side plate of the panel frame 2. This effectively avoids the force displacement problem of the panel frame 2 caused by asynchronous clamping, ensuring positioning accuracy. Teflon material also possesses high-temperature resistance and wear resistance, maintaining stable performance during long-term, high-frequency clamping operations, reducing the frequency of maintenance and replacement of positioning components, and lowering production costs. Furthermore, the low coefficient of friction of Teflon material prevents scratches when the long-side positioning strip 6 contacts the panel frame 2, effectively protecting the surface quality of the panel frame 2 and avoiding damage to the product's appearance during the positioning and clamping process.

[0035] like Figure 7 As shown, the feeding and pressing mechanism 4 includes two limiting seats 41 set on the upper part of the workbench 1. A limiting rod 42 is rotatably set between the opposite ends of the two limiting seats 41. An arc plate 43 is fixedly set on the outside of both ends of the limiting rod 42. A base plate 44 is set between the other ends of the two arc plates 43. A pressing frame 45 is set on the upper part of the base plate 44. A silicone pad is set on the pressing side of the pressing frame 45 to prevent the glass panel from being crushed during pressing. Four adsorption components 46 are arranged in a matrix inside the pressing frame 45 on the upper part of the base plate 44, corresponding to each support column 9 in sequence. A bent handle 47 is set at each of the two corners on the side of the base plate 44 away from the arc plate 43. A grip rod 48 is connected between the two bent handles 47.

[0036] like Figure 7 As shown, the central axis of the limiting rod 42 is flush with the mounting groove on the upper part of the panel frame 2. A long-side baffle 11 is provided on the upper part of the worktable 1 near the long side of the pressing frame 45, and a short-side baffle 12 is provided near the short side of the pressing frame 45. After the long and short sides of the glass panel are respectively attached to the long-side baffle 11 and the short-side baffle 12, when the base plate 44 is rotated clockwise, the panel adsorbed by the adsorption component 46 can be accurately attached to the mounting groove on the panel frame 2, thereby ensuring that the glass panel can fall into the mounting groove accurately and without error, avoiding glue overflow or loose adhesion caused by positional deviation. The setting of the long-side baffle 11 and the short-side baffle 12 provides a reference for quick positioning of the glass panel before loading. The operator only needs to attach the edge of the glass panel to the baffle to ensure that the panel adsorbed by the adsorption component 46 is in the preset loading coordinate position, which greatly reduces the difficulty of manual loading and improves loading efficiency and accuracy.

[0037] like Figures 7 to 8 As shown, the adsorption assembly 46 includes a guide tube 461, which is fixed to the base plate 44. A tube 462 slides longitudinally through the guide tube 461. A suction cup 463 is connected to the upper end of the tube 462. The glass panel is adsorbed onto the suction cup 463 by a vacuum pump. The upper side of the pressing frame 45 is higher than the upper end of the tube 462 and lower than the upper side of the suction cup 463. A flange 464 is provided at the outer edge of the upper end of the tube 462. A limiting spring 465 is sleeved on the outside of the tube 462 between the flange 464 and the guide tube 461. The two ends of the limiting spring 465 are connected to the bottom of the flange 464 and the upper end of the guide tube 461, respectively.

[0038] In this solution, after the panel frame 2 is positioned, the six-axis glue-applying robot 3 applies glue to the mounting slot on the upper part of the panel frame 2. After application, the glass panel is placed on the four suction components 46, so that the long side of the glass panel abuts against the long side baffle 11 and the short side abuts against the short side baffle 12. This way, when the glass panel is loaded, it will be precisely locked into the mounting slot on the upper part of the panel frame 2. After the panel is positioned, the suction cup 463 will hold the panel in place under the action of the air pump. Then, the operator holds the handle 4. 8. Rotate the base plate 44 clockwise upwards to flip the panel onto the mounting slot on the upper part of the panel frame 2. Then, press the base plate 44 downwards forcefully. Under the elasticity of the limit spring 465, the suction cup 463 will gradually move upwards as the base plate 44 is pressed down. When the clamping frame 45 contacts the panel, continue to press the base plate 44 so that the clamping frame 45 presses the panel into the mounting slot on the panel frame 2, ensuring full adhesion with the adhesive. This prevents cracks or damage to the glass panel due to excessive local pressure. During this process, the compression of the limit spring 465 can directly reflect the magnitude of the clamping force. Operators can judge by touch or monitor in real time with an external pressure sensor to ensure that the applied clamping force is within the safe threshold range that the glass panel can withstand. This ensures full contact between the adhesive and the panel while avoiding product damage caused by excessive pressure.

[0039] like Figure 7 and Figures 9 to 10 As shown, the feeding and clamping mechanism 4 also includes a limiting mechanism 49 to prevent the base plate 44 from rotating counterclockwise. The limiting mechanism 49 includes a protrusion 491 disposed at one end of one of the handles 47, a handle 492 hinged to the bottom of the handle 47, a ratchet 493 and ratchet teeth 494 rotatably disposed on one side of the limiting seat 41 corresponding to the handle 47, and a limiting block 495 fixedly installed on one side of the limiting seat 41. One end of the ratchet 493 is connected to the limiting rod 42. The limit block 495 and the ratchet 494 are connected by a return spring 496, so that when the return spring 496 is in the reset state, one end of the ratchet 494 is engaged with the ratchet 493, so that the ratchet 493 can only rotate clockwise in one direction. An outer tube 497 is connected between the protrusion 491 and the limit block 495. An inner wire 498 is installed inside the outer tube 497. The two ends of the inner wire 498 are connected to the handle 492 and the ratchet 494 respectively.

[0040] In this solution, when the clamping frame 45 presses the panel, the ratchet 494 is stuck on the ratchet 493, which can only rotate clockwise and not counterclockwise. Therefore, after releasing the handle 48, the clamping frame 45 will not leave the panel but will continue to press the panel. After the glue solidifies, the suction cup 463 will release its adsorption of the glass panel. Then, the operator will squeeze the handle 492 upwards, which will pull the inner wire 498 to move. The other end of the inner wire 498 will pull the ratchet 494 to move, causing it to leave the teeth of the ratchet 493, allowing the ratchet 493 to rotate counterclockwise. At this time, the operator will flip the base plate 44 counterclockwise to return it to its initial position, which will facilitate the loading of the next panel. This realizes the automated reset and cyclic operation of the loading and clamping mechanism. Throughout the limiting process, the return spring 496 consistently applies a preload force to the ratchet 494, ensuring tight engagement between the ratchet 494 and the ratchet wheel 493, effectively preventing limiting failure due to vibration or external interference. The outer tube 497 guides and protects the inner cable 498, preventing friction and wear between the inner cable 498 and other components during frequent pulling, thus extending the service life of the limiting mechanism. The ergonomic design of the grip 492 enhances ease of operation; its anti-slip texture increases hand friction, preventing slippage during operation and ensuring the operator can easily and accurately control the disengagement of the ratchet 494.

[0041] Furthermore, to ensure the operational accuracy of the six-axis glue-applying robot 3, the equipment also integrates a vision positioning system. This system includes a high-definition industrial camera and a laser contour sensor mounted on the end effector of the robot. Before glue application, the camera captures images of the mounting slot on the panel holder 2, accurately extracts the edge contour coordinates of the slot using image recognition algorithms, and compares and calibrates them with the preset glue application path, correcting the robot's trajectory in real time. The laser contour sensor dynamically detects the depth and width of the mounting slot. When a dimensional deviation exceeds the allowable range, the system automatically pauses the glue application and issues an alarm, reminding the operator to reposition or replace the panel holder 2, preventing uneven glue application or missed areas due to abnormal workpiece dimensions. Simultaneously, the vision positioning system also features glue height detection, monitoring the height and width of the glue line in real time during application to ensure the glue filling amount meets process requirements, further improving the consistency of product bonding quality.

[0042] In terms of the equipment's control system, a PLC is used as the core control unit, and a touch screen is used to realize the human-machine interface. Operators can set parameters such as the pre-clamping pressure, normal working pressure, and holding time of the long-side positioning hydraulic cylinder 5 and the short-side positioning hydraulic cylinder 7 on the touch screen, and can monitor the working status of each actuator in real time, such as the extension and retraction position of the hydraulic cylinder, the feedback value of the pressure sensor, and the running progress of the glue-applying robot. The system has a parameter storage function, which can save the corresponding process parameter groups for different specifications and models of panel frame 2. When changing product models, the corresponding parameter group can be called to quickly complete the equipment debugging, which significantly shortens the changeover time. The control system also integrates a fault self-diagnosis module, which can monitor and alarm for common equipment faults such as sensor abnormalities, hydraulic cylinder jamming, and insufficient vacuum pump pressure in real time, and display fault codes and troubleshooting suggestions on the touch screen, which facilitates maintenance personnel to quickly locate and solve problems, improving the equipment's uptime.

[0043] A panel adhesive application production method includes applying adhesive to the panel using panel adhesive application equipment, as detailed below: S1. Place the panel frame 2 on the support column 9 on the workbench 1 to support the panel frame 2; S2. The six-axis glue-applying robot 3 applies glue to the glass panel mounting slot on the panel frame 2. S3. The glass panel is adsorbed onto the suction cup 463 by the vacuum pump, and then the base plate 44 is flipped over so that the glass panel is pressed tightly against the mounting groove on the panel frame 2. S4. After the glue solidifies, release the glass panel from the adsorption process. Then, by adjusting the limiting mechanism 49, release the counterclockwise rotation limit of the base plate 44, so that the base plate 44 rotates counterclockwise back to the initial position, and feed the next glass panel.

[0044] Working Principle: This panel gluing equipment provides stable support for the panel frame 2 via support columns 9 on the worktable 1. Combined with long-side and short-side positioning mechanisms, it achieves precise positioning of the panel frame 2. During positioning, a pressure sensor controls the long-side positioning hydraulic cylinder 5 and the short-side positioning hydraulic cylinder 7 to output low pressure for pre-clamping. Utilizing the Teflon material properties of the long-side positioning strip 6, even if the two positioning mechanisms move asynchronously, the panel frame 2 can adaptively adjust under the action of the smooth surface, ensuring that the long-side positioning strip 6 and the short-side positioning plate 8 precisely fit the inner corner of the panel frame 2. Then, it switches to normal operating pressure to complete the final clamping. An angle adjustment component precisely controls the tilt angle of the long-side positioning hydraulic cylinder 5, further improving positioning accuracy. After positioning, the six-axis gluing robot 3, guided by the vision positioning system, accurately executes the preset gluing path based on the mounting groove contour coordinates collected by the high-definition industrial camera and the dimensional parameters detected by the laser contour sensor. The laser contour sensor monitors the depth and width of the mounting groove in real time, dynamically adjusting the robot's glue output and movement speed to ensure that the glue line height, width, and filling density meet the process standards. After the adhesive is applied, the loading and pressing mechanism 4 precisely transfers the glass panel to the top of the panel holder 2 via the adsorption component 46. The long side baffle 11 and the short side baffle 12 assist in the rapid positioning of the glass panel, ensuring its relative positional accuracy with the mounting groove. Subsequently, the operator flips the base plate 44, and under the one-way locking action of the limiting mechanism 49, the pressing frame 45, together with the silicone pad, applies a uniform and continuous pressing force to the glass panel. The elastic buffering effect of the limiting spring 465 prevents glass breakage caused by rigid contact. At the same time, the pressure sensor monitors the pressing force in real time, ensuring that it is within the optimal range between sufficient adhesive wetting and safe pressure bearing of the glass. During this process, the Teflon long side positioning strip 6 not only prevents surface scratches on the panel holder 2, but its low friction characteristics also effectively eliminate stress offset that may be caused by the asynchronous operation of the long and short side positioning mechanisms, further ensuring positioning accuracy. After the adhesive has fully cured and reached the set strength, the vacuum suction of suction cup 463 is released. The operator then squeezes handle 492 to drive inner wire 498, causing ratchet 494 to disengage from ratchet 493, thus resetting the base plate 44 counterclockwise and completing a full panel adhesive application cycle. The entire system uses a PLC control system to achieve logical linkage and parameter optimization of each actuator. The touchscreen human-machine interface provides convenient parameter setting, status monitoring, and fault diagnosis functions, significantly improving the ease of operation and production reliability of the equipment. This achieves automation and high-precision control of the entire process of panel frame positioning, precision adhesive application, glass bonding, and curing pressure holding, effectively improving the production efficiency and product yield of panel components.
