Description

Technical Field

[0001] The invention relates to the technical field of SGP plate interior decoration part processing, in particular to a device for automatically spraying glue on SGP plate interior decoration parts. Background Art

[0002] The glue spraying robot is mainly composed of the robot body, computer and corresponding control system. The hydraulically driven glue spraying robot also includes a hydraulic oil source, such as an oil pump, oil tank and motor; all its work is completed with high efficiency, durability, speed and accuracy.

[0003] Because glue spraying poses significant risks to the human body, industrial robots are rapidly developing in the glue spraying industry to replace manual glue spraying. During the glue spraying process, the robot's mechanical arm drives the spray gun to spray glue in various ways, such as spot, sweep, and atomized. Existing spot glue spraying robots generally use a single spray gun, which is inefficient and unable to quickly cover large areas. The limited spray range also limits the number of workpieces that can be processed in a single spraying operation. Furthermore, after spraying, the glue needs to be transported to another workstation for drying, resulting in low production and processing efficiency. Summary of the Invention

[0004] In order to meet the above-mentioned demand for fast and efficient glue spraying by glue spraying robots, the present invention proposes a device to solve the problem of automatic glue spraying of SGP sheet interior parts.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0006] A device for automatically spraying glue on SGP sheet interior parts, comprising a circular rotary chassis, a multi-nozzle glue spraying robot distributed at the center of the circular rotary chassis, and a plurality of posting boards arranged symmetrically along the circumferential direction on the rotating surface of the circular rotary chassis. The posting boards rotate with the circular rotary chassis;

[0007] Drying devices are distributed in the space area surrounded by the circular revolving chassis to dry the surface of the SGP sheet interior parts after spraying.

[0008] It also includes a telescopic blocking fork and two blocking plates arranged on the telescopic blocking fork. The telescopic blocking fork can be extended and retracted back and forth to drive the two blocking plates to extend above the circular rotary chassis to block the left and right sides of the poster board on the glue spraying station of the multi-nozzle glue spraying robot.

[0009] As a further improvement of the present invention, the distance between the two blocking plates is greater than the width of the posting board.

[0010] As a further improvement of the present invention, the drying and heating area of the drying device can cover at least the area of one posting board 7.

[0011] As a further improvement of the present invention, the drying device is a heating plate with an arc-shaped structure.

[0012] As a further improvement of the present invention, the multi-nozzle glue spraying robot includes a robotic arm. At the front end of the robotic arm, there are multiple mechanical fingers that can move synchronously or independently. And a spray gun of a glue spraying component is correspondingly arranged on each mechanical finger. Each of the spray guns operates independently of each other. The mechanical fingers are controlled by a first hydraulic cylinder inside for synchronous opening and closing of multiple fingers, or are controlled by a second hydraulic cylinder corresponding to each finger for adjusting the opening angle of each finger.

[0013] As a further improvement of the present invention, the mechanical finger includes a cylindrical base fixed to the robotic arm. Inside the base, there is the first hydraulic cylinder. The output end of the first hydraulic cylinder is fixedly connected to a disc. Multiple groups of folding plates are annularly arranged on the outer surface of the disc. Multiple groups of mounting columns are arranged on the outer wall of the base. One end of a second hydraulic cylinder is hinged to each mounting column. The other end of the second hydraulic cylinder is rotatably connected to the corner of the folding plate.

[0014] As a further improvement of the present invention, the folding plate and the second hydraulic cylinder form a finger. One end of the folding plate is hinged to the hinge seat of the disc. The rotating plate of the second hydraulic cylinder is rotatably connected to a rotating groove opened at the corner of the folding plate. The hinge plate of the second hydraulic cylinder is rotatably connected to the mounting column.

[0015] As a further improvement of the present invention, the first hydraulic cylinder controls the rotation of one end of each folding plate through the disc to realize the synchronous operation of each finger; the second hydraulic cylinder adjusts the opening angle of the finger corresponding to it by pushing and pulling the corner of the folding plate.

[0016] As a further improvement of the present invention, a fixing ring for fixing the spray gun is arranged at the front end of the folding plate. The fixing ring abuts against the outer wall of the spray gun through a fastening bolt.

[0017] As a further improvement of the present invention, each spray gun corresponds to a branch pipe. And the branch pipe passes through the limit hole of the mounting column. One end of each branch pipe is fixed to the outer wall of a collecting ring sleeved outside the base. And each branch pipe corresponds to a valve. The lower part of the collecting ring is communicated with an oil glue bucket through a main pipe.

[0018] As a further improvement of the present invention, the robotic arm includes a horizontally rotatable base, a large arm is rotatably connected to the base, a small arm is rotatably connected to the upper end of the large arm, the front end of the small arm is fixed to the flange of the base through a connecting arm, and the sides of the large arm and the small arm are fixedly connected with a limiting ring for limiting the main pipe.

[0019] Beneficial effects of the present invention:

[0020] The present invention can realize automatic glue spraying and drying processing, adopts a cyclic operation mode, improves production and processing efficiency while also reducing overall space utilization;

[0021] The present invention provides mechanical fingers that can open and close synchronously and can also adjust the angle individually, driving the corresponding installed glue spraying components to spray glue. When the first hydraulic cylinder of the mechanical fingers is in operation, all the mechanical fingers are controlled to open and close, thereby controlling the glue spraying coverage of the entire glue spraying component to adapt to glue spraying positions of different sizes. When the second hydraulic cylinder of the mechanical fingers is in operation, the corresponding mechanical fingers are controlled to rotate, thereby adjusting the angle of a single spray gun, and multiple spray guns that can perform separate point spraying can be used for independent glue spraying processing of multiple small workpieces. The number of single glue spraying processing is increased while retaining the point spraying function of the original spray gun, thereby improving overall work efficiency.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be explained more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention, not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0031] like Figures 1 to 6 As shown, a device for automatically spraying glue for SGP sheet interior parts includes a circular rotary chassis 6, a multi-nozzle glue spraying robot 8 distributed in the center of the circular rotary chassis 6, and a plurality of posting plates 7 are arranged symmetrically along the circumferential direction on the rotating surface of the circular rotary chassis 6. The posting plates 7 rotate with the circular rotary chassis 6;

[0032] A drying device 9 is distributed in the space area surrounded by the annular rotary chassis 6 to dry the surface of the SGP sheet interior decoration parts after spraying.

[0033] It also includes a telescopic blocking fork 4 and two blocking plates 5 arranged on the telescopic blocking fork 4. The telescopic blocking fork 4 can be extended and retracted back and forth to drive the two blocking plates 5 to extend above the circular rotary chassis 6 to block the left and right sides of the posting board 7 on the glue spraying station of the multi-nozzle glue spraying robot 8.

[0034] The circular rotary chassis 6 of the present invention can rotate around the horizontal plane, thereby driving the posting board 7 to operate, so as to change the position of the posting board 7. After the posting board 7 to be spray-glued rotates to the position directly opposite the multi-nozzle spray-gluing robot 8, the circular rotary chassis 6 stops rotating. At this time, the already spray-glued posting board 7 has rotated to the area where the drying device 9 is located, and starting the drying device 9 can dry the SGP board interior trim on the already spray-glued posting board 7. After the posting board 7 to be spray-glued rotates to the position directly opposite the multi-nozzle spray-gluing robot 8, the telescopic blocking fork 4 can be started to drive the blocking plate 5 to block the left and right sides of the posting board 7 at the spray-gluing station of the multi-nozzle spray-gluing robot 8, and then the multi-nozzle spray-gluing robot 8 is started for spray-gluing treatment.

[0035] After the spray-gluing is completed, the telescopic blocking fork 4 drives the blocking plate 5 to retract. In this way, the circular rotary chassis 6 starts to rotate, and the spray-glued SGP board interior trim can be rotated to other stations, while the SGP board interior trim to be spray-glued follows the posting board 7 and rotates to the position directly opposite the multi-nozzle spray-gluing robot 8, and the spray-gluing operation can be repeated.

[0036] For the driving source of the telescopic blocking fork 4, it can be an external air cylinder to push the telescopic blocking fork 4 to perform horizontal telescopic movement.

[0037] The rotary drive of the circular rotary chassis 6 of the present invention can be a working mode in which a motor drives a gear and the gear drives a gear ring to operate, which belongs to the well-known technology in this industry.

[0038] Such as Figure 1 and Figure 2 As shown, the distance between the two blocking plates 5 of the present invention is greater than the width of the posting board 7. In this way, when the two blocking plates 5 extend above the circular rotary chassis 6, the posting board 7 at the spray-gluing station can be separated between the two blocking plates 5, which can prevent the glue from splashing onto other posting boards 7 during the spray-gluing process.

[0039] The drying and heating area of the drying device 9 can cover at least the area of one posting board 7.

[0040] Specifically, as Figure 1 and shown, the posting board 7 of the present invention can be set to 6, and then the drying device 9 can cover two or three posting boards 7.

[0041] The drying device 9 is a heating plate with an arc-shaped structure.

[0042] The multi-nozzle glue spraying robot 8 includes a robotic arm 1, and a plurality of robotic fingers 2 that can move synchronously or independently are arranged at the front end of the robotic arm 1. A spray gun 31 of a glue spraying assembly 3 is correspondingly arranged on each robotic finger 2, and each of the spray guns 31 operates independently of each other. The robotic fingers 2 are controlled by a first hydraulic cylinder 22 inside for synchronous opening and closing of multiple fingers, or are controlled by a second hydraulic cylinder 26 corresponding to each finger for adjusting the opening angle of each finger.

[0043] The robotic finger 2 includes a cylindrical base 21 fixed to the robotic arm 1. The first hydraulic cylinder 22 is arranged inside the base 21. The output end of the first hydraulic cylinder 22 is fixedly connected to a disc 23. A plurality of groups of folding plates 24 are annularly arranged on the outer surface of the disc 23. A plurality of groups of mounting posts 25 are arranged on the outer wall of the base 21. One end of a second hydraulic cylinder 26 is hinged to each mounting post 25, and the other end of the second hydraulic cylinder 26 is rotatably connected to the corner of the folding plate 24.

[0044] The folding plate 24 and the second hydraulic cylinder 26 form a finger. One end of the folding plate 24 is hinged to a hinge seat 231 on the disc 23. A rotating plate 262 of the second hydraulic cylinder 26 is rotatably connected to a rotating groove 241 opened at the corner of the folding plate 24. A hinge plate 261 of the second hydraulic cylinder 26 is rotatably connected to the mounting post 25. The front and rear ends of the second hydraulic cylinder 26 are respectively rotated through the hinge plate and the rotating plate 262 with the mounting post 25 and the corner of the folding plate 24, so that the second hydraulic cylinder 26 automatically performs rotational cooperation during the telescopic process.

[0045] The first hydraulic cylinder 22 controls one end of each folding plate 24 to rotate through the disc 23 to achieve synchronous operation of each finger; the second hydraulic cylinder 26 adjusts the opening angle of the corresponding finger by pushing and pulling the corner of the folding plate 24. When controlled by the first hydraulic cylinder 22, each second hydraulic cylinder 26 remains stationary, so that the folding plate 24 can rotate around the rotating plate 262 of the second hydraulic cylinder 26 at the corner; when controlled by the second hydraulic cylinder 26, the first hydraulic cylinder 22 remains different, so that the folding plate 24 can rotate around the hinge seat 231 on the disc 23.

[0046] A fixing ring 242 for fixing the spray gun 31 is arranged at the frontmost end of the folding plate 24. The fixing ring 242 abuts against the outer wall of the spray gun 31 through a fastening bolt 243. The arrangement of the fixing ring 242 and the fastening bolt 243 facilitates disassembly and installation, and is used for quickly replacing and repairing the spray gun 31.

[0047] Each spray gun 31 corresponds to a branch pipe 32, which passes through the limiting hole 251 of the mounting column 25. One end of each branch pipe 32 is fixed to the outer wall of a collecting ring 34 sleeved on the outside of the base 21. Each branch pipe 32 corresponds to a valve 33. The lower part of the collecting ring 34 is connected to the oil and glue barrel 36 through the main pipe 35. The valve 33 can be configured as a solenoid valve or other electrically controlled valve. When performing a unified spray, all valves 33 are open, and the oil and glue amount is directly controlled by the pump. Conversely, when using a single or a small number of spray pipes, the corresponding valve 33 is opened to allow the oil and glue to pass through, while the remaining valves 33 are closed, and the pump supplies a small amount of oil and glue.

[0048] The robotic arm 1 includes a horizontally rotatable base 11, a large arm 12 is rotatably connected to the base 11, a small arm 13 is rotatably connected to the upper end of the large arm 12, the front end of the small arm 13 is fixed to the flange 211 of the base 21 through a connecting arm 14, and the sides of the large arm 12 and the small arm 13 are fixedly connected with a limiting ring 15 for limiting the main pipe 35.

[0049] The horizontally rotatable base 11 drives the entire mechanical finger 2 and the glue spraying assembly 3 to adjust the horizontal angular position. The large arm 12, small arm 13 and connecting arm 14 that automatically adjust the angle are used to adjust the height angle of the mechanical finger 2 and the glue spraying assembly 3, so that the injection pipe sprays glue facing the glue spraying area of the workpiece. The setting of the limit ring 15 is used to limit and suspend the position of the main pipe 35, so that the main pipe 35 extends with the mechanical arm 1 to avoid interfering with the operation of the mechanical arm 1.

[0050] When the multi-nozzle glue spraying robot 8 is in use: start the base 11 to rotate horizontally, then start the upper arm 12, the lower arm 13 and the connecting arm 14 to send the mechanical finger 2 to the starting point of glue spraying, then start the pump in the glue barrel 36 to introduce the glue into the collecting ring 34 through the main pipe 35, and connect the branch pipe 32 connected to the collecting ring 34 to each spray gun 31 for spraying.

[0051] Mechanical finger 2 control: When it is necessary to control all the spray guns 31 to carry out large-scale coverage spraying, the first hydraulic cylinder 22 is started, and the first hydraulic cylinder 22 pushes the disc 23 to move outward. The outward movement of the disc 23 drives one end of the folding plate 24 hinged thereto to rotate outward with the rotating plate 262 of the second hydraulic cylinder 26 as the fulcrum, thereby dispersing the various spray guns 31 and expanding the entire coverage area; when it is necessary to control all the spray guns 31 to carry out point spraying to one part: the first hydraulic cylinder 22 is started to drive the disc 23 to retract, and the retraction of the disc 23 drives one end of the folding plate 24 hinged thereto to rotate inward with the rotating plate 262 of the second hydraulic cylinder 26 as the fulcrum, thereby bringing the various spray guns 31 together inward.

[0052] When single finger spraying is required: Start the second hydraulic cylinder 26. The second hydraulic cylinder 26 drives the rotating plate 262 to push the corner of the folding plate 24, so that the folding plate 24 rotates around the end hinged to the disc 23, thereby adjusting the angle of the folding plate 24, and further controlling the spraying position change of the spray pipe corresponding to the folding plate 24.

[0053] Furthermore: Multiple second hydraulic cylinders 26 can be simultaneously controlled for angle adjustment, so that each finger corresponds to a small workpiece. It is also possible to control the first hydraulic cylinder 22 to further adjust the angle of the folding plate 24 by the second hydraulic cylinder 26, and spray at different positions of the workpiece corresponding to the spray pipe.

[0054] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
