Description

Technical Field

[0001] This invention relates to the field of adhesive coating equipment, and more particularly to an adhesive coating machine for automobile floor production. Background Technology

[0002] The adhesive coating process for vehicle floor panels effectively improves the structural strength of the floor panel, enhances vehicle operational safety, and strengthens the corrosion resistance of the floor panel, especially at the edges and welded areas, preventing corrosion. Additionally, adhesive coating can fill in uneven areas on the floor panel surface, resulting in a smoother and more aesthetically pleasing vehicle appearance.

[0003] Related technology can be found in Chinese Patent No. CN206882033U, which discloses a robotic adhesive application system for automotive painting. This system includes a high-station adhesive application unit, a low-station adhesive application unit, and an intermediate transfer unit located between them. Each of the high-station and low-station adhesive application units includes two oppositely positioned adhesive application robots and two oppositely positioned travel tracks for the robots to move. Vehicle body conveying equipment is parallel to each other between the travel tracks. A glue gun mounted on each adhesive application robot is connected to an adhesive delivery control system, which includes a fluid tray and a PCF controller connected to the fluid tray. A visual positioning device is provided between the vehicle body conveying equipment and the travel tracks. This adhesive application device can perform adhesive application operations on different parts of the vehicle body at both the high and low stations, thereby applying adhesive to all parts of the vehicle body, both inside and out.

[0004] Regarding the aforementioned technologies, since the adhesive being sprayed is liquid, although the adhesive can be sprayed onto the vehicle at high speed through a pressurized adhesive delivery system, a small amount of mist-like adhesive still fails to adhere to the vehicle during the application process and drifts down to the robot below the vehicle under the influence of gravity. Therefore, the adhesive application robot needs to be covered with a protective film, such as a plastic film, during operation to prevent the mist-like adhesive from adhering to the robot. However, due to the complex structure of the vehicle's undercarriage, the adhesive application robot needs to move repeatedly along a predetermined trajectory. During this process, the protective film can easily interfere with the movement of the adhesive application robot and affect its heat dissipation, making the adhesive application process quite inconvenient. Summary of the Invention

[0005] To improve the convenience of the adhesive application process, this application provides an adhesive application machine for automobile floor production.

[0006] This application provides a glue-applying machine for automobile floor production, which adopts the following technical solution: A glue-applying machine for automobile floor production includes a robotic arm with a glue-applying gun at its movable end. The robotic arm also has a glue supply mechanism for feeding glue to the glue-applying gun. The glue-applying gun includes a mounting part, a rotating part, and a spray tube. The mounting part is connected to the movable end of the robotic arm. The rotating part is located at the end of the mounting part away from the robotic arm, and a rotating column is fixedly mounted on the rotating part laterally. Both ends of the rotating column pass through the mounting part and are rotatably connected to it. The mounting part has a drive component for driving the rotating part to rotate. The spray tube is arranged sequentially along the robotic arm, the mounting part, and the rotating part, and is connected to the glue supply mechanism. A nozzle is provided at the end of the spray tube away from the glue supply mechanism. Baffle plates are provided on both sides of the rotating column along the diameter direction. The two baffle plates cooperate to surround the mounting part circumferentially. The baffle plates are recessed in the direction from the rotating part to the mounting part, and an air extraction pipe is connected to the end of the baffle plate away from the rotating part. The baffle plate has an air inlet that communicates with the air extraction pipe. An air extraction assembly is provided on one side of the robotic arm to generate negative pressure in the air extraction pipe.

[0007] By adopting the above technical solution, during operation, the car floor is lifted, and a robotic arm drives the glue gun to extend under the car floor. The glue supply mechanism feeds the glue into the spray nozzle, and the robotic arm moves the mounting and rotating parts, which in turn moves the nozzle. The glue in the spray nozzle is sprayed out and applied to the car floor. When it is necessary to apply glue to the transverse structure of the car floor, the rotating part is driven by the rotating component to rotate around the rotating column, thereby adjusting the nozzle angle. During the spraying process, both baffles are located below the nozzle. When the air extraction component is working, it extracts gas from the spraying area of ​​the nozzle through the air extraction pipe and air inlet, thereby removing the splashed atomized glue and reducing the probability of glue falling onto the robotic arm, which helps to improve the convenience of the glue application process.

[0008] Optionally, the mounting part near the rotating part has two parallel rotating plates fixedly connected, and a rotating column is located between the two rotating plates. The rotating column passes through the rotating plates and is rotatably connected to them. The driving component includes an electric actuator, a driving rod, and a connecting rod. One end of the rotating column along its length passes through the rotating plates and is vertically fixed to a straight plate. The connecting rod is vertically hinged to the straight plate. The driving rod is slidably connected to the mounting part along its length. The end of the connecting rod away from the straight plate is hinged to the driving rod. The electric actuator is fixedly connected to the mounting part and is used to drive the driving rod to rotate.

[0009] By adopting the above technical solution, the installation part supports the rotating column through the rotating plate, so that the rotating column rotates around its own axis. When the electric actuator drives the drive rod to move, the drive rod drives the straight plate to rotate through the connecting rod, so that the straight plate drives the connecting column to rotate, and then drives the rotating part to rotate.

[0010] Optionally, a reset torsion spring is provided between the rotating column and the rotating plate. In its natural state, the straight plate is perpendicular to the mounting part, and the rotating part and the mounting part are located in the same straight line.

[0011] By adopting the above technical solution, when the driving component drives the rotating part to rotate, the reset torsion spring is in a deformed state. When the driving component resets, the reset torsion spring elastically drives the rotating part to return to its original state, thereby reducing the probability of the rotating part getting stuck when rotating.

[0012] Optionally, the two baffles are provided with mounting openings on their adjacent sides, and both rotating plates are located in the mounting openings. Each baffle is fixed with a support plate corresponding to a rotating plate, and each support plate is fixed with a mounting post corresponding to a rotating plate. The mounting post passes through the rotating plate and is rotatably connected to it. An elastic element is provided between the baffle and the rotating plate. In its natural state, the baffle and the mounting part are perpendicular to each other. The spray gun is provided with a rotating element for driving the baffle to rotate.

[0013] By adopting the above technical solution, the mounting part is located inside the mounting opening, so that the baffle plate is close to the mounting part. The rotating plate supports the baffle plate through the mounting column and the support plate, so that the baffle plate rotates around the mounting column. The elastic plate is used to limit the baffle plate, so that the baffle plate receives the atomized adhesive. When the rotating part needs to drive the nozzle to extend into the groove structure of the car floor, if the baffle plate interferes with the car floor, the rotating part will rotate the corresponding baffle plate, so that the baffle plate avoids the car floor, further improving the working flexibility of the baffle plate.

[0014] Optionally, the rotating component corresponds one-to-one with the baffle plate. The rotating component includes a first gear, a second gear, and an abutment block. The first gear is coaxially fixed to the mounting column of the corresponding baffle plate. The second gear is coaxially rotatably connected to one end of the rotating column along the length direction and meshes with the first gear. An arc-shaped block is coaxially fixed on the side of the second gear away from the rotating plate. The two arc-shaped blocks in the two sets of rotating components are located on both sides of the rotating column. The abutment block is fixedly connected to the rotating column and abuts against the lower end of the arc-shaped block.

[0015] By adopting the above technical solution, when the rotating part rotates, the rotating column drives the two abutting blocks to move synchronously. At this time, one abutting block contacts the arc-shaped block and drives the arc-shaped block to move, while the other abutting block gradually moves away from the corresponding arc-shaped block. When the arc-shaped block moves, it drives the corresponding gear two to rotate, so that gear two drives the mounting column to rotate through gear one, so that the mounting column drives the corresponding baffle plate to flip, so that the baffle plate avoids the car floor.

[0016] Optionally, the baffle plate has a clearance opening that communicates with the installation port. A movable plate is provided at the clearance opening. The movable plate is vertically hinged to the baffle plate on the side away from the installation part. An elastic element two is provided between the baffle plate and the movable plate. In its natural state, the movable plate is completely located inside the clearance opening and fits against the inner wall of the clearance opening.

[0017] By adopting the above technical solution, the elastic element two limits the movable plate. When the baffle plate avoids the car floor, the movable plate approaches and contacts the mounting part. At this time, the mounting part moves out of the avoidance opening, and the elastic element two deforms, thereby reducing the interference between the baffle plate and the mounting part.

[0018] Optionally, the baffle plate has an internal accommodating cavity that is connected to the air extraction pipe, and several air inlets are evenly distributed along the upper surface of the baffle plate, all of which are connected to the accommodating cavity.

[0019] By adopting the above technical solution, the accommodating cavity connects all the air inlets to the air extraction pipe, thereby facilitating the expansion of the extraction range of the air inlet and extraction pipe and improving the cleaning effect on the mist-like adhesive material.

[0020] Optionally, both baffles are fixed with baffles along the circumference. The baffles are located at the upper end of the baffles and are perpendicular to the baffles. The end face of the baffle facing the mounting part is recessed, and the recessed side of the baffle is provided with a number of holes communicating with the receiving cavity.

[0021] By adopting the above technical solution, when the baffle plate is flipped, the baffle edge helps to reduce the probability of the rubber material above the baffle plate slipping off. At the same time, the baffle edge temporarily stores the rubber material that accumulates on the upper surface of the baffle plate, and sucks the rubber material into the receiving cavity through the dividing hole and discharges it through the air extraction pipe, further improving the convenience of cleaning the rubber material.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During operation, the car floor is lifted, and the robotic arm moves the glue gun underneath. The glue supply mechanism feeds the glue into the spray nozzle. The robotic arm moves the mounting and rotating parts, which in turn moves the nozzle. The glue in the spray nozzle is sprayed out and applied to the car floor. When it is necessary to apply glue to the transverse structure of the car floor, the rotating part is rotated around the rotating column by the rotating component, thereby adjusting the nozzle angle. During the spraying process, both baffles are located below the nozzle. When the air extraction component is working, it extracts the gas from the spraying area of ​​the nozzle through the air extraction pipe and air inlet, thereby removing the splashed atomized glue and reducing the probability of glue falling onto the robotic arm, which improves the convenience of the glue application process. 2. The mounting section supports the rotating column through the rotating plate, so that the rotating column rotates around its own axis. When the electric actuator drives the drive rod to move, the drive rod drives the straight plate to rotate through the connecting rod, so that the straight plate drives the connecting column to rotate, and in turn drives the rotating part to rotate. 3. The mounting part is located inside the mounting opening, so that the baffle plate is close to the mounting part. The rotating plate supports the baffle plate through the mounting column and the support plate, so that the baffle plate rotates around the mounting column. The elastic plate is used to limit the baffle plate, so that the baffle plate receives the atomized adhesive. When the rotating part needs to drive the nozzle to extend into the groove structure of the car floor, if the baffle plate interferes with the car floor, the rotating part will rotate the corresponding baffle plate, so that the baffle plate avoids the car floor, further improving the working flexibility of the baffle plate.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses an adhesive applicator for automobile floor production.

[0031] Example: Reference Figure 1 and Figure 2A glue-applying machine for automobile floor production includes a robotic arm 1 and a glue-applying gun 2. The glue-applying gun 2 includes a mounting part 21, a rotating part 22, and a glue-spraying tube 23. The mounting part 21 is mounted on the movable end of the robotic arm 1, and the robotic arm 1 drives the mounting part 21 to move when it is working. The rotating part 22 is located at the end of the mounting part 21 away from the robotic arm 1, and the mounting part 21 is fixedly connected to two parallel rotating plates 211.

[0032] Reference Figure 2 and Figure 3 The rotating part 22 is fixedly connected to a rotating column 221 corresponding to the rotating plate 211. The rotating column 221 passes through the rotating plate 211 and is rotatably connected to the rotating plate 211. When the mounting part 21 moves, it drives the rotating part 22 to move through the rotating plate 211 and the rotating column 221. A return torsion spring 224 is provided between the rotating column 221 and the rotating plate 211. One end of the return torsion spring 224 is fixedly connected to the rotating plate 211, and the other end is fixedly connected to the rotating column 221. In its natural state, the rotating part 22 and the mounting part 21 are located in the same straight line.

[0033] Reference Figure 1 and Figure 2 A glue supply mechanism 3 is provided on one side of the robotic arm 1. The glue supply mechanism 3 is used to transport high-speed flowing glue. The glue supply mechanism 3 is existing technology, so it will not be described in detail here. The glue spraying pipe 23 is arranged sequentially along the length of the rotating part 22, the mounting part 21 and the robotic arm 1. A nozzle 222 is installed at the end of the rotating part 22 away from the mounting part 21. One end of the glue spraying pipe 23 is connected to the nozzle 222, and the other end is connected to the glue supply mechanism 3. When the glue supply mechanism 3 is working, it feeds the glue into the glue spraying pipe 23, so that the paint is sprayed out from the nozzle 222.

[0034] Reference Figure 2 and Figure 4 The rotating part 22 has baffles 4 on both sides along the transverse direction. The two baffles 4 are located on both sides of the rotating column 221 along the radial direction. The baffles 4 have a mounting opening on the side near the mounting part 21, and the mounting part 21 is located in the mounting opening, so that the baffles 4 are close to the mounting part 21. The baffles 4 are fixedly connected to support plates 42 that correspond one-to-one with the rotating plate 211. The support plates 42 are vertically fixed to mounting columns 43. The mounting columns 43 are parallel to the rotating column 221 and pass through the rotating plate 211 and are rotatably connected to the rotating plate 211. An elastic element 44 is provided between the mounting column 43 and the rotating plate 211. The elastic element 44 is a torsion spring. One end of the torsion spring is fixedly connected to the mounting column 43 and the other end is fixedly connected to the rotating plate 211. In its natural state, the baffles 4 are perpendicular to the mounting part 21.

[0035] Reference Figure 2 and Figure 4The mounting section 21 is equipped with a driving component 24, which includes an electric actuator 241, a driving rod 242, and a connecting rod 243. A straight plate 223 is vertically fixed to the end of the rotating column 221 away from the rotating section 22. In its natural state, the straight plate 223 is perpendicular to the mounting section 21. The connecting rod 243 is rotatably connected to the straight plate 223 vertically, and the driving rod 242 is slidably connected to the mounting section 21 vertically. The end of the connecting rod 243 away from the straight plate 223 is rotatably connected to the driving rod 242. When the driving rod 242 moves, it drives the rotating column 221 to rotate via the connecting rod 243 and the straight rod. The electric actuator 241 is fixedly connected to the mounting section 21 and is used to drive the driving rod 242 to move.

[0036] Reference Figure 2 and Figure 3 When the rotating column 221 rotates, it drives the rotating part 22 to rotate, thereby adjusting the angle between the rotating part 22 and the nozzle 222 and the mounting part 21, increasing the working range of the nozzle 222. During the rotation of the rotating part 22, the return torsion spring 224 is in a deformed state. When the electric push rod 241 drives the drive rod 242 to reset, the return torsion spring 224 drives the rotating part 22 to reset. In other embodiments, the drive component 24 can also be other mechanisms, such as a combination of a motor, a lead screw, and a gear set.

[0037] Reference Figure 1 and Figure 4 The baffle plate 4 has an internal cavity 411, and its upper surface has multiple air inlets 41 communicating with the cavity 411. An air extraction pipe 51 is located below the baffle plate 4 and communicates with the cavity 411. An air extraction assembly 52 is also provided on one side of the robot arm 1. This assembly creates a negative pressure within the air extraction pipe 51. When a negative pressure is created in the air extraction pipe 51, gas is drawn from above the baffle plate 4 through the cavity 411 and the air inlets 41.

[0038] Reference Figure 2 and Figure 4 During the adhesive spraying process, if the atomized adhesive sprayed from nozzle 222 does not adhere to the car floor, the baffle plate 4 collects the atomized adhesive and draws it into the suction pipe 51 through the air inlet 41, from where it is discharged. The suction assembly 52 is also equipped with a filter cartridge. The atomized adhesive enters the filter cartridge along the suction pipe 51 for filtration. Both ends of the suction pipe 51 are detachable for easy replacement.

[0039] Reference Figure 2 and Figure 3The baffle plate 4 has a retaining edge on the side away from the mounting part 21. When the baffle plate 4 rotates, it drives the retaining edge to rotate. A groove is provided on the side of the retaining edge near the mounting part 21. A rotating component is provided between the rotating part 22 and the baffle plate 4. The rotating component corresponds to the baffle plate 4 one by one. The rotating component includes a first gear 61, a second gear 62 and an abutment block 63. The first gear 61 is coaxially rotatably connected to the rotating column 221, and an arc-shaped block 611 is coaxially fixed on the side of the first gear 61 away from the rotating plate 211. When the arc-shaped block 611 moves, it drives the first gear 61 to rotate.

[0040] Reference Figure 2 and Figure 3 Gear 2 62 is coaxially fixed with mounting post 43, and gear 1 61 meshes with gear 2 62. When gear 1 61 rotates, it drives mounting post 43 to rotate through gear 2 62, thereby causing mounting post 43 to rotate baffle 4. Abutment block 63 is fixedly connected to rotating post 221, and the abutment blocks 63 of the two rotating parts are arranged opposite each other with the axis of rotating post 221 as the center, and the two abutment blocks 63 are located at both ends of rotating post 221. When rotating post 221 rotates, it drives abutment block 63 to move. In the initial state, abutment block 63 is located on one side of arc plate. When rotating post 221 drives the two abutment blocks 63 to rotate, one abutment block 63 approaches arc block 611 and pushes arc block 611 to move, while the other abutment block 63 gradually moves away from the corresponding arc block 611.

[0041] Reference Figure 2 and Figure 3 When there is a groove structure on the car floor and adhesive needs to be sprayed onto the inner wall of the groove, the rotating part 22 is driven to rotate by the rotating component. When the rotating part 22 drives the nozzle 222 to rotate toward any baffle plate 4, the abutment block 63 corresponding to the baffle plate 4 gradually moves away from the corresponding arc plate, and the baffle plate 4 is in a stationary state. The abutment block 63 corresponding to another baffle plate 4 drives the corresponding gear 62 to rotate through the arc block 611, which in turn drives the corresponding gear 61 to rotate. At this time, the baffle plate 4 flips toward the mounting part 21. The flipped baffle plate 4 avoids the groove structure on the vehicle floor, making it easier for the rotating part 22 to extend into the groove. At this time, the baffle plate 4 near which the nozzle 222 is close is still in working state, making it easier to pick up the atomized adhesive sprayed by the nozzle 222.

[0042] Reference Figure 2 and Figure 4 During the process of absorbing the atomized adhesive, if any adhesive accumulates above the baffle plate 4, when the baffle plate 4 flips, the baffle edge blocks the adhesive accumulated on the baffle plate 4, preventing the adhesive from sliding off the baffle plate 4. The baffle plate 47 has a dividing hole 471 communicating with the receiving cavity 411. When the adhesive accumulates in the groove on the baffle plate 47, the adhesive on the baffle edge is absorbed through the dividing hole 471, further improving the convenience of adhesive absorption.

[0043] Reference Figure 4 and Figure 5 The baffle plate 4 has a clearance opening 45 adapted to the mounting opening. A movable plate 46 is installed inside the clearance opening 45. The side of the movable plate 46 away from the mounting part 21 is vertically hinged to the baffle plate 4. An elastic element 461, also a torsion spring, is provided between the movable plate 46 and the baffle plate 4. One end of the torsion spring is fixedly connected to the movable plate 46, and the other end is fixedly connected to the baffle plate 4. Under the action of the elastic element 461, the baffle plate 4 moves, causing the movable plate 46 to move. When the baffle plate 4 approaches the mounting part 21, the movable plate 46 first contacts the mounting part 21. At this time, the baffle plate 4 continues to rotate, causing the movable plate 46 to rotate out from the clearance opening 45, thereby avoiding the mounting part 21 and further improving the storage effect of the baffle plate 4.

[0044] Reference Figure 4 and Figure 5 The baffle plate 4 has an opening on the side opposite to the mounting part 21, and an extension plate 48 is provided on the outer side of the baffle plate 4. The extension plate 48 is arranged around the baffle plate 4 and is detachably connected to the baffle plate 4 by bolts. In the initial state, the opening is blocked. When the spraying range of the nozzle 222 exceeds the working range of the baffle plate 4, the opening is opened, and the extension plate 48 is installed on the outer side of the baffle plate 4. The extension plate 48 has a cavity adapted to the opening, and the upper end of the extension plate 48 has a through hole communicating with the cavity. The extension plate 48 is used to expand the working range of the baffle plate 4 and further improve the working convenience of the baffle plate 4.

[0045] The implementation principle of a glue applicator for automobile floor production according to an embodiment of this application is as follows: During the glue application process, the automobile floor is lifted by a hoisting tool, and the robotic arm 1 moves the glue gun 2 to below the automobile floor. The glue supply mechanism 3 feeds the glue into the spray pipe 23, so that the glue is sprayed out from the nozzle 222 and applied to the automobile floor. During the glue application process, both baffles 4 are located below the nozzle 222. The air extraction component 52 works, so that the air extraction pipe 51 extracts the gas in the accommodating cavity 411, and then absorbs the gas below the spraying range of the nozzle 222 through the air inlet 41, thereby removing the splashed mist of glue generated during the spraying process, reducing the probability of glue falling onto the robotic arm 1, and improving the convenience of the glue application process.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
