Description

Technical Field

[0001] This invention belongs to the technical field of window sash adhesive application devices, and particularly relates to an automatic window sash adhesive application workstation. Background Technology

[0002] Existing window sash adhesive application methods generally employ two approaches: manual application and mechanical application. Manual application requires workers to hold a glue gun, resulting in low efficiency, poor adhesive evenness, and difficulties in flipping the window sash for application on both sides. While a utility model patent (CN217140976U, August 9, 2022) discloses an "adhesive application device for metal door and window processing," this patent only allows for single-sided adhesive application. Material loading and unloading still require manual operation, leading to low efficiency and limiting operation to one window sash at a time. It cannot simultaneously prepare for the next window sash or transfer the previously applied sash, nor can it address the need to use different glue guns for different window sashes. Therefore, an automated window sash adhesive application workstation is urgently needed to overcome these problems in existing technologies. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic adhesive application workstation for window sashes to solve the aforementioned problems existing in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An automatic adhesive application workstation for window sashes includes a lifting material exchange platform, an assisting arm, an adhesive application station, an adhesive supply system, a robot, an adhesive gun holder, multiple adhesive guns, a contact depth sensor, and a vision recognition unit. The assisting arm is located on one side of the lifting material exchange platform and works in conjunction with it. The front end of the lifting material exchange platform corresponds to and is abutted against the rear end of the adhesive application station. The vision recognition unit is located on one side of the adhesive application station. The adhesive supply system, the robot, and the adhesive gun holder are all located on the other side of the adhesive application station. The robot works in conjunction with both the adhesive application station and the adhesive gun holder. One of the adhesive guns is detachably mounted on the robot's movable end via a quick-change disc mechanism. The other adhesive guns are detachably mounted on the adhesive gun holder. The adhesive supply system is connected to one of the adhesive guns via a supply hose. A contact depth sensor is fixed to the front end of the adhesive gun. The contact depth sensor and the vision recognition unit are respectively connected to the robot via signals.

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] 1. The automatic glue application workstation for window sashes of the present invention is equipped with a lifting material exchange platform and a glue application station. The loading and unloading of the lifting material exchange platform can be completed with the assistance of a manual operation arm. The lifting material exchange platform is equipped with two movable supports. The lifting material exchange platform and the glue application station are used together to prepare for the glue application of the next workpiece or to transfer the previous workpiece after it is completed while gluing the current workpiece. This saves manpower and time while improving work efficiency.

[0008] 2. The automatic glue application workstation for window sashes of the present invention has a glue gun installed at the moving end of the robot. The front end of the glue gun is equipped with a contact-type depth detection sensor. The glue gun is connected to the glue supply system through a glue supply hose. The contact-type depth detection sensor can detect the distance between the glue gun and the workpiece during glue application to meet the glue application requirements. The glue supply system can continuously and stably supply glue, which not only improves work efficiency but also results in a higher finished product qualification rate compared to manual labor.

[0009] 3. The automatic glue application workstation for window sashes of the present invention has a lifting and flipping mechanism at the glue application station. After glue is applied to one side of the workpiece, the workpiece can be lifted and flipped by the lifting and flipping mechanism to perform glue application on the other side, realizing double-sided glue application of the workpiece. There is no need to manually flip the workpiece, saving manpower and time and improving work efficiency.

[0010] 4. The automatic glue application workstation for window sashes of the present invention has a replacement glue gun mounted on the glue gun bracket. The robot's moving end is connected to the glue gun through a quick-change disc mechanism, which can quickly replace the glue gun for different types of workpieces to meet the glue application requirements. There is no need for manual operation to replace the glue gun, saving time and making it highly adaptable.

[0011] 5. The automatic glue application workstation for window sashes of the present invention has a linkage clamping unit on the tray of the movable bracket, which can center and clamp workpieces of different sizes, ensuring stable clamping and smooth completion of glue application and flipping of workpieces.

[0044] Furthermore, the visual recognition unit includes a camera bracket 13 and a visual camera 14. The camera bracket 13 is fixed to one side of the glue application station 7, and the visual camera 14 is fixed to the camera bracket 13.

[0045] Before starting work, the operator adjusts the two movable supports 47 on the lifting material exchange platform 5, specifically adjusting the linkage clamping unit 55 fixed on the tray 52. ​​The linkage clamping unit 55 is adjusted to a suitable size for clamping the workpiece to be processed (the workpiece being the window sash). The linkage clamping unit 55 is manually adjusted by the operator. Based on the size of the workpiece, the operator moves the two mounting plates 72 in opposite directions. One end of the mounting plate 72 has a timing belt pressure plate 69 fixedly connected to the timing belt 68 of the longitudinal transmission assembly. The mounting plate 72 is fixedly connected to the mounting plate 57, and the mounting plate 57 is fixedly connected to the slider 71 of the longitudinal sliding assembly. The timing belt 69 of the longitudinal transmission assembly... The transmission of the two drive wheels 67 and the sliding of the sliders 68 and slide rails 70 of the two longitudinal sliding components causes the two mounting plates 72 to move towards each other to a suitable longitudinal position. Then, the two slide plates 62 on the mounting plate 57 are manually adjusted to move towards each other. The slide plates 62 are fixedly connected to the timing belt pressure plate 60. The transmission of the two slide plates 62 is achieved through the timing belt 59 and the two drive wheels 58 of the transverse transmission component, and the sliding of the sliders 63 and slide rails 61 of the two transverse sliding components causes the two slide plates 62 to move towards each other to a suitable transverse position. That is, the four corners of the workpiece to be processed can be placed in the four limit plates 64. Then, the brake caliper 65 is adjusted to switch to the braking state, so that the entire linkage clamping unit 55 is in the locked state.

[0046] During operation, the staff uses the assist arm 6 to remove a workpiece to be processed from the raw material area 3 and place it on the tray 52 of the upper movable support 47 of the lifting material exchange platform 5. The linkage clamping unit 55 in the tray 52 clamps and fixes the workpiece to be processed, and then the assist arm 6 is removed.

[0047] The lifting material exchange platform 5 and the glue application station 7 are used in conjunction. The screw lifting mechanism 41 of the lifting material exchange platform 5 descends, causing the guide rail 45 of the lifting material exchange platform 5 to align with the guide rail 17 of the glue application station 7. This allows the hanging rod 27 to engage with the traction frame 53 at the front end of the upper movable support 47 of the lifting material exchange platform 5. The motor 29 of the glue application station 7 is then started, driving the chain transmission mechanism to rotate and causing the transmission shaft to move. This, in turn, causes the slider 25 on the slide rail 24 to slide, which in turn moves the hanging rod 27 on the hanging plate 26 fixedly connected to the slider 25. This moves the upper movable support 47 of the lifting material exchange platform 5 towards the glue application station 7. The roller at the lower end of the upper movable support 47... 49 rolls on the guide rail 17 of the glue application station 7. The upper moving bracket 47 holding the workpiece to be processed is transported to the glue application station 7 by the traction mechanism 18. After the workpiece to be processed is in place, the vision camera 14 of the vision recognition unit identifies the glue path of the workpiece to be processed and sends a signal to the robot 9. The robot 9 carries the glue gun 11 to the workpiece to be processed. When the distance between the glue gun 11 and the workpiece to be processed reaches the glue application standard distance, the contact depth detection sensor 12 sends a signal to prevent the nozzle of the glue gun 11 from getting too close to the workpiece to be processed. Then, the glue supply system 8 is started to deliver glue to the glue gun 11. The robot 9 drives the glue gun 11 to apply glue to one side of the workpiece to be processed.

[0048] After the adhesive is applied to one side of the workpiece, the two telescopic cylinders 34 of the lifting and tilting mechanism 19 extend simultaneously, causing the lifting support plates 35 at both ends of the support legs 33 to slide and rise along the sliding bracket 42. The U-shaped support plates 38 at the upper ends of the two lifting support plates 35 contact the rotating shafts 15 on the tilting transmission wheels 54 at both ends of the upper moving bracket 47, thereby driving the pallet 52 to rise. After the lifting and tilting mechanism 19 lifts the pallet 52, the tilting transmission wheels 54 at both ends of the pallet 52 contact the synchronous belts 37 of the belt drive units on the two lifting and tilting mechanisms 19. When the pallet 52 rises to the point where the rotating transmission wheels 54 rotate... When shaft 15 contacts the limit block 21 on the limit frame 20, the two telescopic cylinders 34 stop simultaneously. At this time, the servo motor 39 starts and drives the flipping transmission wheel 54 to rotate through the transmission wheel 36 of the transmission unit and the synchronous belt 37, so that the pallet 52 flips 180°, that is, the workpiece that is half processed is flipped to the other side. After the flipping is completed, the two telescopic cylinders 34 of the lifting and flipping mechanism 19 retract simultaneously, so that the lifting support plates 35 at both ends of the support leg 33 slide down along the sliding bracket 42 at the same time and return to their original positions. Then, the previous glue application steps are repeated to apply glue to the other side of the workpiece to be processed.

[0049] After the other side is coated with adhesive, repeat the lifting and flipping action of the lifting and flipping mechanism 19, and then flip the processed workpiece back to the initial surface.

[0050] During the gluing process on the workpiece to be processed on the upper movable support 47, the lifting material exchange platform 5 can perform the loading and clamping of the workpiece to be processed on the lower movable support 47. By repeating the loading action of the lifting material exchange platform 5, the operator uses the assist arm 6 to remove a workpiece to be processed from the raw material area 3 and place it on the tray 52 of the lower movable support 47 of the lifting material exchange platform 5. The linkage clamping unit 55 in the tray 52 clamps and fixes the workpiece to be processed, and then the assist arm 6 is removed.

[0051] After the workpiece to be processed on the lower moving bracket 47 is loaded and clamped, the previous workpiece that has been coated with glue is transferred. That is, the upper moving bracket 47 is pulled in the opposite direction to transport the upper moving bracket 47 back to the lifting material exchange table 5.

[0052] Afterwards, the screw lifting mechanism 41 of the lifting material exchange platform 5 is raised, so that the roller 50 at the lower end of the lower moving bracket 47 of the clamped workpiece to be processed is connected and slid with the guide rail 17 on the glue application station 7, and then it is transported to the glue application station 7 for glue application. The operation steps are the same as those of the upper moving bracket 47.

[0053] When the workpiece on the lower movable support 47 is being glued, the screw lifting mechanism 41 of the lifting material exchange platform 5 descends. The worker uses the assist arm 6 to complete the processing and unload the workpiece to the finished product area 4. Then the loading action is repeated, and the next workpiece to be processed in the raw material area 3 is transported to the upper movable support 47 and clamped by the linkage clamping unit 55, waiting for glue to be applied.

[0054] Repeat the above steps to achieve uninterrupted loading, unloading, and gluing of the upper and lower movable brackets 47.

[0055] The linkage clamping unit 55 can clamp workpieces of different specifications and sizes in the center;

[0056] The glue gun holder 10 is detachably fixed with a replaceable glue gun 11, which can meet the glue application requirements of different models and glue application requirements of workpieces. The quick-change disc mechanism enables the quick installation and disassembly of different models of glue guns 11 and robot 9.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
