Description

Technical Field

[0001] This invention belongs to the field of automotive adhesive spraying technology, specifically relating to an automotive headliner adhesive spraying device. Background Technology

[0002] During the production process, car roofs typically require the installation of sound insulation cotton or decorative fabric. These parts need to be secured with adhesive during installation, necessitating the pre-application of adhesive on the car roof. Current adhesive application methods usually involve robotic arms or manual assistance. While robotic arms can achieve rapid adhesive application to car roofs, their purchase and subsequent maintenance costs are high. Therefore, most small and medium-sized processing plants currently still use manual adhesive application. However, manual adhesive application may result in adhesive adhering to workers, affecting their health, and also reduces the quality and efficiency of the application process.

[0003] To address the aforementioned technical issues, Chinese patents disclose an automotive roof adhesive spraying device (patent publication number: CN217911287U). This device utilizes the interaction of a second sliding groove and a second electric slider to facilitate adjustment of the clamping height. By adjusting the length of the telescopic sleeve, the clamp can be positioned appropriately according to the size of the parts to be sprayed, clamping and fixing them securely. An electric rotating shaft can rotate the clamped parts, ensuring more comprehensive adhesive application. Furthermore, a similar automotive roof adhesive spraying device (patent publication number: CN218108214U) is also disclosed. This device uses a clamp assembly to fix the automotive roof, and the spraying head can move at multiple angles under the action of front-to-back and left-to-right moving blocks to spray adhesive onto the automotive roof.

[0004] Although the above technical solutions solve the problem of low efficiency caused by the manual spraying of adhesive in existing car roofs, the above technical solutions all spray adhesive on the car roof by moving the spray nozzle. There is a time difference between the start and end of the spraying process, which may cause the area where the adhesive was first sprayed to solidify for a period of time, resulting in a decrease in adhesion. This leads to the problem of inconsistent adhesion between the sprayed areas at the front and rear ends and the subsequent decorative fabric. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an adhesive spraying device for automobile roofs, which can solve the problem that the prior art cannot achieve synchronous adhesive spraying for automobile roofs.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0009] Furthermore, the transmission assembly includes a transmission shaft, a transmission screw, a first rack, and a first driven gear; the transmission screw is rotatably connected to the lower surface of the movable block and is arranged along the direction of movement of the support housing; the support housing is threadedly connected to the transmission screw; the transmission shaft is rotatably connected inside the movable block and is arranged along the direction of movement of the movable block; one end of the transmission screw extends into the movable block and is transmitted to the transmission shaft via a bevel gear set; the first rack is fixed inside the support platform and is arranged along the direction of movement of the movable block; the first driven gear is rotatably connected inside the movable block and is transmitted to the transmission shaft via a bevel gear set; a portion of the surface of the first driven gear extends out of the movable block and meshes with the first rack.

[0010] Furthermore, each of the supporting housings has an elongated through hole on one side surface; each of the supporting housings has multiple spaced-apart adjusting rods inside; the width of the through hole is greater than the diameter of the adjusting rod; each adjusting rod is perpendicular to the through hole, and one end of the adjusting rod passes through the through hole and is threaded with a bolt, while the other end is slidably connected to the inner wall of the supporting housing; each adjusting rod has multiple adjusting blocks inserted through it, and the upper surface of the adjusting blocks abuts against the lower surface of the supporting housing; the length of each adjusting block can be adjusted vertically.

[0011] Furthermore, the telescopic block is hollow inside, and the spray nozzle is rotatably disposed inside the telescopic block; a second driven gear is connected to the rotation center of the spray nozzle; a movable block that moves vertically is elastically inserted through the top of the telescopic block; a vertically arranged second rack is fixed on the lower surface of the movable block, and the second rack meshes with the second driven gear; a third adhesive channel is also provided inside the adjusting block; the third adhesive channel is located above the first adhesive channel, and one end of the third adhesive channel is connected to an external adhesive pump, while the other end abuts against the surface of the telescopic block; a second electromagnet is also fixed inside the adjusting block and is disposed opposite to the movable block, and the second electromagnet will attract the movable block when energized.

Detailed Implementation

[0029] like Figures 1-9 As shown,

[0030] A car roof adhesive spraying device includes support platforms 1 located on both sides of a vehicle frame (not shown in the figure) and clamping components 2 mounted on the upper surface of the support platforms 1; two spaced movable blocks 3 are horizontally slidably passed through opposite sides of the support platforms 1; a power component for driving the movable blocks 3 is provided on the support platforms 1; a support housing 5 is slidably passed through the lower surface of each movable block 3, and the movement direction of the support housing 5 is perpendicular to the movement direction of the movable block 3; multiple adjusting blocks 6 are provided on the lower surface of the support housing 5; each adjusting block 6 is provided with an adhesive spraying head 8, and the opening of the adhesive spraying head 8 extends out of the adjusting block 6 and points vertically downward; a transmission component 12 for driving the support housing 5 is provided on the movable blocks 3, and when the vehicle frame is located between the two support platforms 1 and fixed by the clamping component 2, the support housing 5 extends after the movable blocks 3 extend a certain distance out of the support platforms 1, until the side surfaces of the multiple support housings 5 ​​abut against each other, and the car roof is within the coverage area of ​​the multiple adhesive spraying heads 8.

[0031] In this solution, before applying adhesive to the car roof, the car frame to be coated is first flipped so that the roof is closest to the ground. Then, the frame is moved between two support platforms 1. The clamping components 2 on the support platforms 1 clamp and fix the car frame, ensuring the accuracy of the subsequent adhesive application. The power component in this solution is a first hydraulic telescopic rod 4. After the frame is fixed, the first hydraulic telescopic rod 4 is activated, driving the movable blocks 3 towards the frame. Since there are front pillars supporting the roof and bottom of the frame, the movable blocks 3 on each support platform 1 are spaced apart, with each movable block 3 corresponding to the front and rear doors of the frame. After the movable blocks 3 have extended a certain distance under the action of the first hydraulic telescopic rod 4, the support housing 5, driven by the transmission component 12, begins to extend the movable blocks 3 (the support housing 5 does not move synchronously with the movable blocks 3). The movement is also to prevent the extended support housing 5 from colliding with the front pillar of the car. At this time, the two movable blocks 3 on the support platform 1 will move towards each other until the support housing 5 extends and abuts against the surface of the support housing 5 on the corresponding other support platform 1. At this time, the four support housings 5 ​​are exactly above the roof of the vehicle frame, and the four support housings 5 ​​completely cover the roof of the vehicle frame. The multiple glue spraying heads 8 on the support housing 5 spray glue on the roof of the car at the same time, completing the glue spraying work of the roof in one go. There is no need to move the vehicle frame or the spraying head, which greatly speeds up the glue spraying speed and improves work efficiency. After the glue spraying is completed, the first hydraulic telescopic rod 4 drives the movable block 3 to reset, and the support housing 5 slides into the inside of the movable block 3 at the same time. Finally, after the movable block 3 is completely slid into the support platform 1, the vehicle frame that has been glued is moved, and the next vehicle frame is moved between the two clamping components 2. The above operation process can be repeated.

[0032] In this embodiment, the lower surfaces of multiple adjusting blocks 6 are elastically fitted with telescopic blocks 7 that move vertically; the lower surface of each telescopic block 7 is provided with a first electromagnet 9; the interior of each adjusting block 6 is provided with a first adhesive channel 10; one end of the first adhesive channel 10 is connected to an external adhesive pump (not shown in the figure), and the other end abuts against the surface of the telescopic block 7; the interior of each telescopic block 7 is provided with a second adhesive channel 11; one end of the second adhesive channel 11 is connected to a spray nozzle 8, and the other end abuts against the inner wall of the adjusting block 6. When the adjusting block 6 is located above the car roof, the first electromagnet 9, in an energized state, attracts the car roof and drives the telescopic block 7 to move together, so that the first adhesive channel 10 and the second adhesive channel 11 are coaxial and connected.

[0033] Combination Figure 9As shown, a first spring 25 is provided between the top of the telescopic block 7 and the inner wall of the adjusting block 6. One end of the first spring 25 is fixedly connected to the surface of the telescopic block 7, and the other end is fixedly connected to the inner wall of the adjusting block 6. Since some vehicles have sunroofs and some do not, in order to identify whether a car has a sunroof, a first electromagnet 9 is fixed at the bottom of the telescopic block 7. When multiple adjusting blocks 6 move close to the car roof, since the car frame is made of high-strength steel plate, the first electromagnet 9 is energized. The first electromagnet 9 will drive the telescopic block 7 to move towards the car roof. At this time, the first spring 25 is stretched, and the second adhesive channel 1... 1 will also move with the telescopic block 7. After the telescopic block 7 moves a certain distance toward the car roof, it will abut against the adjusting block 6. At this time, one end of the second adhesive channel 11 is exactly coaxial with one end of the first adhesive channel 10 and connected to each other. The external adhesive pump can then deliver the adhesive to the spray nozzle 8 for spraying (the spray nozzle 8 has a gap with the car roof after it descends with the telescopic block 7). Multiple spray nozzles 8 spray adhesive onto the car roof at the same time. The part of the car roof with the sunroof will not attract the first electromagnet 9, so the telescopic block 7 at this position will not move. Naturally, the first adhesive channel 10 and the second adhesive channel 11 at this location will not be connected. Figure 8 As shown, the glue spray head 8 will not spray glue on this area; therefore, through the cooperation of the simple telescopic block 7, the first spring 25 and the first electromagnet 9, it is possible to automatically spray glue on the roof of the vehicle frame with or without a sunroof, which can effectively reduce glue waste and production costs. Furthermore, since there are many types of vehicle frames, and the roofs of vehicle frames with different areas can attract different numbers of telescopic blocks 7, it is possible to automatically spray glue on the roofs of vehicle frames with different areas, which improves the applicability of this device and greatly improves work efficiency.

[0034] In this scheme, the transmission assembly 12 includes a transmission shaft 1201, a transmission lead screw 1202, a first rack 1203, and a first driven gear 1204; the transmission lead screw 1202 is rotatably connected to the lower surface of the movable block 3, and the transmission lead screw 1202 is arranged along the movement direction of the support housing 5; the support housing 5 is threadedly connected to the transmission lead screw 1202; the transmission shaft 1201 is rotatably connected to the inside of the movable block 3, and the transmission shaft 1201 is arranged along the movement direction of the movable block 3; the transmission lead screw 1201... One end of 02 extends into the interior of the movable block 3 and is driven by a bevel gear set to drive the transmission shaft 1201; the first rack 1203 is fixed inside the support platform 1 and is arranged along the movement direction of the movable block 3; the first driven gear 1204 is rotatably connected inside the movable block 3 and is driven by a bevel gear set to drive the transmission shaft 1201; a portion of the surface of the first driven gear 1204 extends out of the movable block 3 and meshes with the first rack 1203.

[0035] Combination Figure 5 As shown, to improve the stability of the movement of the supporting housing 5, two transmission screws 1202 are used in this design. The two transmission screws 1202 are horizontally spaced apart. One end of each transmission screw 1202 extends into the interior of the movable block 3 and is connected to a bevel gear. There is a height difference between the first driven gear 1204 and the transmission shaft 1201, and a bevel gear (obscured in the figure and not shown) is also provided on the side of the first driven gear 1204 near the transmission shaft 1201. Three bevel gears are coaxially fixed on the surface of each transmission shaft 1201. Two bevel gears mesh with the bevel gear on the transmission screw 1202, and another bevel gear meshes with the bevel gear on the first driven gear 1204. To prevent the support housing 5 from colliding with the uprights on the frame when it moves, the first rack 1203 is not always meshed with the first driven gear 1204. The first driven gear 1204 only meshes with the first rack 1203 when one end of the movable block 3 extends a certain distance from the support platform 1 and begins to enter the frame. When the first driven gear 1204 rotates, it drives the transmission shaft through the bevel gear set. When 1201 rotates, the drive shaft 1201 drives two transmission screws 1202 to rotate via a bevel gear set. The transmission screws 1202 then drive the support housing 5 to move axially. When the end face of the movable block 3 on each support platform 1 abuts against the end face of the movable block 3 on another support platform 1, the four support housings 5 ​​also abut against each other in pairs, covering the car roof, so that multiple glue spraying heads 8 can spray glue onto the car roof simultaneously. After the glue spraying is completed, because the first driven gear 1204 meshes with the first rack 1203, the movable block 3 retracts from the support platform 1. During the process, the support housing 5 will also retract into the movable block 3. When the first driven gear 1204 is no longer meshed with the first rack 1203, the support housing 5 will retract completely into the movable block 3, while the movable block 3 will continue to drive the support housing 5 to retract into the support platform 1. The linear motion of the first hydraulic telescopic rod 4 is converted into the rotation of the transmission screw 1202 through the transmission assembly 12, so that the movable block 3 will drive the support housing 5 to extend or retract while moving, which improves the degree of automation, without the need for additional motors or telescopic cylinders, and reduces production costs.

[0036] In this embodiment, each of the supporting housings 5 ​​has an elongated through hole 14 on one side surface; each of the supporting housings 5 ​​has multiple spaced adjusting rods 13 inside; the width of the through hole 14 is greater than the diameter of the adjusting rod 13; each adjusting rod 13 is perpendicular to the through hole 14, and one end of the adjusting rod 13 passes through the through hole 14 and is threaded with a bolt 19, while the other end is slidably connected to the inner wall of the supporting housing 5; each adjusting rod 13 has multiple adjusting blocks 6 inserted through it, and when the bolt 19 is tightened, the adjusting rod 13 abuts against the upper side wall of the through hole 14, at which time the upper surface of the adjusting block 6 abuts against the lower surface of the supporting housing 5; the length of the adjusting block 6 can be adjusted vertically.

[0037] In this design, the vertical length adjustment of the adjusting block 6 is achieved because it consists of adjusting block 6a601 and adjusting block b602, which are connected by bolt 19. Adjusting block 6a601 slides through the adjusting rod 13. A first spring 25 is placed between the lower surface of adjusting block 6a601 and the upper surface of the telescopic block 7. Twisting adjusting block b602 allows the adjusting block 6 to extend, indirectly adjusting the distance between the spray nozzle 8 and the car roof. Because the car roof is not horizontal but a curved surface with a small angle, adjusting the height of each adjusting block 6 ensures that the distance between the multiple spray nozzles 8 and the car roof is approximately the same after the telescopic block 7 extends (different spacing between the spray nozzles 8 and the roof will affect the spraying range). This ensures that the adhesive sprayed from the spray nozzles 8 evenly covers the car roof, preventing uneven coverage in certain areas of the roof. The problem of excessive adhesive and insufficient adhesive in some areas has occurred. Furthermore, to further improve the uniformity of adhesive spraying on car roofs of different sizes, the distance between each adjusting rod 13 can be adjusted along the length of the through hole 14. Because the width of the through hole 14 is greater than the diameter of the adjusting rod 13, after loosening the bolt 19, the adjusting rod 13 falls onto the lower side wall of the through hole 14, and the top of the adjusting block 6 no longer abuts against the support housing 5. The adjusting block 6 on each adjusting rod 13 can be moved. After adjusting the position, the movable end of the adjusting rod 13 is lifted up so that the upper surface of each adjusting block 6 abuts against the surface of the support housing 5. Finally, the bolt 19 is tightened. By combining the two adjustment methods, the position of the adjusting block 6 on the horizontal plane can be adjusted, which greatly improves the spraying range of the spray head 8, improves the applicability of this device, and improves the uniformity of adhesive spraying on the car roof by the spray head 8, ensuring the firmness of subsequent fixing of decorative fabric or sound insulation cotton.

[0038] In this embodiment, the telescopic block 7 is hollow inside, and the glue spray head 8 is rotatably disposed inside the telescopic block 7; a second driven gear 17 is connected to the rotation center of the glue spray head 8; a movable block 21 that moves vertically is elastically inserted through the top of the telescopic block 7; a vertically arranged second rack 16 is fixed on the lower surface of the movable block 21, and the second rack 16 meshes with the second driven gear 17; a third glue channel 22 is also provided inside the adjusting block 6; the third glue channel 22 is located above the first glue channel 10, and one end of the third glue channel 22 is connected to an external glue pump, and the other end abuts against the surface of the telescopic block 7; a second electromagnet 20 is also fixed inside the adjusting block 6 and is disposed opposite to the movable block 21, and the second electromagnet 20 will attract the movable block 21 when energized.

[0039] When the vehicle frame has a sunroof, the transition surface between the sunroof edge and the roof is usually curved, while the working range of the glue spray head 8 is horizontal. Therefore, to reduce the glue spraying dead angle around the sunroof, the angle of the glue spray head 8 near the sunroof can be adjusted so that the glue spray head 8 can overcome the dead angle; combined with Figure 6 , Figure 7 As shown, a second spring 26 (smaller than the first spring 25 and located inside the first spring 25) is fixedly connected between the movable block 21 and the telescopic block 7. When it is necessary to spray adhesive on the arc-shaped area around the sunroof, the multi-piece adjustment block 6 located inside the sunroof is close to the arc-shaped area around the sunroof (because the sunroof does not attract the first electromagnet 9, the telescopic block 7 located inside the sunroof does not extend towards the car roof). Therefore, the second electromagnet 20 in the multi-piece adjustment block 6 is energized and attracts the movable block 21 to move upward. When the movable block 21 moves upward, the second rack 16 first drives the second driven gear 17 to rotate at a certain angle. The second driven gear 17 drives the spray nozzle 8 to rotate until the surface of the spray nozzle 8 abuts against the inner wall of the telescopic block 7. At this time, the second spring 26 is compressed. After the movable block 21 moves a certain distance, it synchronously drives the telescopic block 7 to move vertically upward together. The movement continues until the top of the moving block 21 abuts against the second electromagnet 20, compressing the first spring 25. At this point, the second adhesive channel 11 and the third adhesive channel 22 are connected, and the spray nozzle 8 is aligned with the arc-shaped area around the sunroof. The position of different spray nozzles 8 aligned with the arc-shaped area of ​​the sunroof can be adjusted by rotating the adjusting block b602, allowing multiple spray nozzles 8 at different angles to work together to spray adhesive onto all arc-shaped areas around the sunroof, reducing dead angles, improving the uniformity of adhesive spraying on the car roof, and ensuring the firmness of the car interior bonding. When the angle adjustment of the spray nozzle 8 is no longer needed, the second electromagnet 20 is de-energized and no longer attracts the moving block 21. The moving block 21 and the telescopic block 7 reset, and the first spring 25 and the second spring 26 extend, causing the second rack 16 to drive the second driven gear 17 to rotate until the opening of the spray nozzle 8 is vertically downward. The reset state is as follows. Figure 8 As shown, at this time, the second adhesive channel 11 abuts against the inner wall of the adjusting block 6, and the spray nozzle 8 is not connected to the external adhesive pump; when the adjusting block 6 is located on the upper surface of the car roof, the first electromagnet 9 drives the telescopic block 7 to move vertically downward. At this time, the first spring 25 is compressed, and the second spring 26 remains stationary, combined with... Figure 9 As shown, after the telescopic block 7 moves downward a certain distance, it comes into contact with the inner wall of the adjusting block 6. At this time, the second adhesive channel 11 is only connected to the third adhesive channel 22.

[0040] In this embodiment, each support platform 1 is rotatably connected to two cleaning rollers 15 for cleaning the spray nozzle 8; the cleaning rollers 15 correspond one-to-one with the movable blocks 3, and the cleaning rollers 15 are located below the movable blocks 3; a third rack 23 is fixed on the lower surface of the movable block 3, and the third rack 23 is arranged along the length direction of the movable block 3; one end of the cleaning roller 15 is coaxially provided with a third driven gear 24 that meshes with the third rack 23; a bracket 18 is also provided on one side of each cleaning roller 15, and the bracket 18 is fixedly connected to the surface of the support platform 1; the surface of the bracket 18 is provided with a high-temperature steam nozzle for assisting in cleaning the spray nozzle 8, and the high-temperature steam nozzle is connected to an external steam pump (the steam pump and the high-temperature steam nozzle are not shown in the figure), and the high-temperature steam nozzle is connected to an external steam pump.

[0041] In this design, after the glue spraying head 8 finishes spraying, both the movable block 3 and the support housing 5 will reset. During this reset period, the glue spraying head 8 will not spray any glue. Therefore, the glue residue on the surface of the glue spraying head 8 will adhere to the opening and solidify, potentially blocking the opening of the glue spraying head 8. To prevent this from happening, when the movable block 3 retracts to the support platform 1 under the action of the first hydraulic telescopic rod 4, the high-pressure steam nozzle sprays high-pressure water vapor to perform preliminary cleaning of the glue spraying head 8, heating the solidified glue and turning it into a liquid. Meanwhile, the third rack 23 on the surface of the support housing 5 will drive the third driven gear 24 on the cleaning roller 15 to rotate, indirectly driving the cleaning roller 15. 5 rotates, and the cleaning roller 15 rotates while cleaning the spray nozzles 8 that pass by in sequence (the surface of the cleaning roller 15 is fixed with bristles), cleaning the liquefied glue on the spray nozzles 8, further improving the cleaning effect of the spray nozzles 8. When it is necessary to spray glue on the roof of the next vehicle frame, the extension of the movable block 3 will also drive the third driven gear 24 to rotate, and the cleaning roller 15 will rotate again and clean the spray nozzles 8 that pass by, ensuring that the spray nozzles 8 are not blocked by glue, so that the glue can be sprayed normally every time the spray nozzles 8 work, ensuring that the glue can be evenly adhered to the surface of the car roof, thereby ensuring the firmness of the interior bonding.

[0042] In this embodiment, the clamping assembly 2 includes a support column 201, a connecting rod 202, a clamping block 203, and a second hydraulic telescopic rod 204. The support column 201 is slidably disposed on the upper surface of the support platform 1 along the length direction of the support platform 1. Two vertically spaced connecting rods 202 are slidably passed through the surface of the support column 201. The ends of the two connecting rods 202 facing the vehicle frame are connected to the clamping block 203. The second hydraulic telescopic rod 204 is fixed on the side of the support column 201 away from the vehicle frame, and the telescopic end of the second hydraulic telescopic rod 204 passes through the support column 201 and is fixed to the surface of the clamping block 203.

[0043] Combination Figure 1 As shown, the clamping block 203 has an arc-shaped structure, which allows the clamping block 203 to better fit the surface of the frame, ensuring the tightness when clamping the frame. The position of the clamping block 203 in contact with the surface of the frame is fixed each time, and it plays a positioning role for the frame, ensuring that the movable block 3 can pass through the doors on both sides of the frame and enter the frame normally. The glue spraying head 8 on the support housing 5 can cover the car roof, ensuring the stability of the glue spraying work.
