Description

Technical Field

[0002] A car's grille is a mesh-like component with a grid at the front of the car. It's located between the front bumper and the front crossbar. Because the hood lock is located on the upper surface of the grille, it needs to be positioned so that the hood lock doesn't penetrate through the grille. Besides being aesthetically pleasing, the main function of a car grille is to allow air to enter and reduce air resistance.

[0003] In order to make the exterior of the car grille more beautiful and adapt to the matching of different car body colors, the car grille needs to be sprayed with paint on the outside after preparation and molding to make the exterior smooth and achieve the preset aesthetics.

DETAILED DESCRIPTION

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] See also Figure 1-7 As shown, a constant pressure atomizing spraying device for automobile grille production includes a spraying assembly and a clamping assembly, wherein the spraying assembly and the clamping assembly are arranged relative to each other, and the spraying assembly includes a rotating base 18, a plurality of rotatable paint spray heads 22 are mounted on one side of the rotating base 18, and a plurality of gas spray heads 14 are mounted on the other side;

[0030] The clamping assembly includes two vertical frames 5, between which a main shaft 7 is rotatably mounted. The outside of the main shaft 7 is equipped with multiple clamping mechanisms, which can be used to clamp the car grille to be sprayed or the test plate 8 used for spraying test.

[0031] As a technical optimization solution of the present invention, the clamping mechanism includes splints 9 on both sides and triangularly arranged rods 6 on both sides. One end of the rod 6 is connected to the outer wall of the main shaft 7. A guide rod 28 is connected between the two ends of the rods 6 on both sides. The two ends of the splint 9 are respectively slidably installed with the two guide rods 28.

[0032] As a technical optimization solution of the present invention, guide seats 30 are connected to the bottom of both ends of the clamping plate 9. The guide seats 30 are mounted on the outside of the guide rod 28. The outer wall of the guide rod 28 is provided with multiple guide grooves along the length direction. The inner wall of the guide seat 30 is connected to multiple second sliders 29. The second sliders 29 are slidably mounted inside the guide grooves, and the multiple second sliders 29 correspond to the multiple guide grooves. The guide seats 30 can slide on the guide rod 28, thereby adjusting the position of the clamping plate 9 during clamping, making the clamped items more secure.

[0033] As a technical optimization solution of the present invention, the bottoms of the opposite surfaces of the two side splints 9 are connected with pads 31 along the length direction, and the opposite surfaces of the two side splints 9 are also connected with buffer pads 32 above the pads 31.

[0034] As a technical optimization solution of the present invention, the bottom sides of the vertical frame 5 are connected to a stabilizing frame 4, which is slidably mounted on the first base 1. The top sides of the first base 1 are provided with first slide grooves 24. The bottom of the stabilizing frame 4 is connected to a first slider 3, which is slidably mounted inside the first slide grooves 24. The first base 1 is also provided with a bottom plate 25. The top sides of the bottom plate 25 are provided with second slide grooves 26. The inside of the second slide groove 26 is slidably mounted with a fourth slider 43. The top of the fourth slider 43 is connected to a second telescopic rod 42. The top of the second telescopic rod 42 is connected to a polishing plate 27. The bottom of the polishing plate 27 is connected to a socket 41, which is plugged into the second telescopic rod 42. During the test, the polishing plate 27 contacts the sprayed surface of the test plate 8. The polishing plate 27 uses the fourth slider 43 at the bottom to move back and forth in the second slide groove 26, thereby performing a friction test on the sprayed surface of the test plate 8. Different grinding plates 27 can be used according to test requirements, and the pressure between the grinding plate 27 and the sprayed surface of the test plate 8 can be adjusted to verify the wear resistance of the sprayed surface. This allows analysis and judgment of whether the paint spraying thickness and spraying method meet the preset usage requirements, facilitating adjustments to the operating mode of the paint spray head 22. The connector 41, which connects to the top of the second telescopic rod 42, facilitates the removal and installation of the grinding plate 27, making it easy to replace different types of grinding plates 27 during testing.

[0035] The first slider 3 can drive the stabilizing frame 4 to slide along the first slide groove 24 on the first base 1, so that after spraying or in subsequent testing, the entire frame can be moved away from the spraying component and will not be affected by the spraying component.

[0036] As a technical optimization solution of the present invention, a rotating rod 35 is rotatably installed on the upper outer side of the vertical frame 5. The side of the rotating rod 35 away from the vertical frame 5 is connected to the second connecting rod 34. The top of the second connecting rod 34 is connected to the first telescopic rod 33. The top of the first telescopic rod 33 is connected to the first connecting rod 12. The end of the first connecting rod 12 on the side of one vertical frame 5 is connected to the second transverse plate 11. The bottom of the second transverse plate 11 is connected to the heating plate 36. The end of the first connecting rod 12 on the side of the vertical frame 5 on the other side is connected to the first transverse plate 10. The bottom of the first transverse plate 10 is provided with a third slide 39. A plurality of third sliders 38 are slidably installed inside the third slide 39. The bottom of the third slider 38 is installed with a paint film meter 37. After the rotating rod 35 is connected to a preset drive motor, it can drive the second connecting rod 34 and the first connecting rod 12 to rotate, thereby driving the first transverse plate 10 or the second transverse plate 11 to rotate. The expansion and contraction of the first telescopic rod 33 can drive the first transverse plate 10 or the second transverse plate 11 to move up and down, thereby making heating and baking and paint thickness measurement more diverse and facilitating adjustment during use.

[0037] As a technical optimization solution of the present invention, the spray assembly also includes a second base 2, one end of the top of the second base 2 is connected to a support column 13, the top of the support column 13 is rotatably mounted with a rotating seat 18, and the top of the rotating seat 18 is mounted with a storage box 16 for storing paint materials. The external paint supply device supplies the storage box 16 with paint coating to be sprayed. The preset constant pressure control device in the storage box 16 can keep the pressure inside the storage box 16 within a preset range, ensuring that the external paint supply device supplies paint coating in a timely manner, so that the paint nozzle 22 can maintain constant pressure and uniform spraying. The control process of constant pressure spraying of paint is an application of existing technology and will not be elaborated on here.

[0038] As a technical optimization of the present invention, a connecting base 17 is connected to one side of the rotating base 18. A flexible connecting tube 19 is connected to the end of the connecting base 17, which is away from the rotating base 18. One end of the connecting tube 19 is connected to the storage tank 16, and the other end is connected to the secondary branch pipe 21. A drive motor at the top of the support column 13 drives the rotating base 18 to rotate horizontally to adapt to different working requirements. The flexible connecting tube 19 can bend as the rotating frame 20 rotates, ensuring normal paint and coating delivery without affecting the rotation of the paint spray head 22.

[0039] As a technical optimization solution of the present invention, a plurality of branch pipes 23 are connected to the side of the secondary branch pipe 21 away from the connecting pipe 19, and the paint nozzle 22 is installed above the end of the branch pipe 23 away from the secondary branch pipe 21, and a camera 40 is also installed on the end of the branch pipe 23 away from the secondary branch pipe 21. A rotating frame 20 is rotatably installed on both sides of the connecting seat 17, and one end of the rotating frame 20 is connected to the outer wall of the secondary branch pipe 21. During use, the rotating frame 20 can drive the secondary branch pipe 21 and the branch pipe 23 to rotate, and then drive the paint nozzle 22 and the camera 40 to rotate, which can adapt to different spraying needs and shooting needs, and expand the scope of work. The camera 40 is a camera lens with a self-cleaning function to maintain an efficient shooting effect. It is the use of existing technology and will not be described in detail here.

[0040] As a technical optimization solution of the present invention, an air pipe 15 is installed on the other side of the rotating base 18, and a gas nozzle 14 is installed on the air pipe 15. A preset air pump is installed on one side of the air pipe 15. When the air pump is working, it can input gas into the air pipe 15, and then spray it out through the gas nozzle 14 to achieve a cleaning effect.

[0041] When the present invention is in use, the first base 1 and the second base 2 are connected and fixed by a reinforcement plate and bolts, so that the positions of the first base 1 and the second base 2 are relatively fixed during use, and various instruments on the upper parts can be used normally. Moreover, the connection in the form of a reinforcement plate facilitates subsequent disassembly and maintenance.

[0042] A test plate 8 for testing is installed on one of the clamping mechanisms, and a car grille to be sprayed is installed on the other clamping mechanism. When the test plate 8 and the car grille are installed and clamped, the clamping mechanism to be used is rotated to the top of the vertical frame 5, and the test plate 8 or the car grille is placed between the two clamping plates 9 on the same clamping mechanism. The bottom of the test plate 8 or the car grille is in contact with the pad 31, and the pad 31 supports it from below, so that when the clamping plate 9 is subsequently moved, the test plate 8 or the car grille is not easy to shake, and the position after clamping is more precise, so that the subsequent spraying work can be carried out better. When the clamping plate 9 moves, the second slider 29 is used to slide in the guide groove through the guide seat 30 at the bottom, so that the clamping plates 9 on both sides can clamp the test plate 8 or the car grille, which can adapt to test plates 8 or car grilles of different sizes. The test plate 8 or the car grille is simple and quick to disassemble and install.

[0043] The storage tank 16 is connected to an external paint supply. A preset constant pressure control device maintains the internal pressure of the storage tank 16 at a preset constant pressure. This ensures uniform paint spraying from the subsequent paint spray heads 22, resulting in a more effective grille painting process. During grille painting, the clamping mechanism holding the grille rotates toward the side of the storage tank 16 via the main shaft 7, and the paint spray heads 22 rotate toward the grille to be painted via the rotating base 18. Multiple cameras 40 on the manifold 23 capture the grille being painted and upload the captured images to a preset backend control system. The backend control system compares the captured grille images with preset grille images. If the comparison results meet preset requirements, the grille meets the applicable standards and can be painted normally. Multiple paint spray heads 22 paint the grille, and during the painting process, the rotating frame 20 drives the secondary manifold 21 to rotate, thereby expanding the spray range of the paint spray heads 22 and ensuring an orderly and stable painting of the grille. After spraying is completed, the second horizontal plate 11 is rotated onto the painted car grille driven by the second connecting rod 34 and the rotating rod 35 at its bottom. The heating plate 36 below the second horizontal plate 11 heats and bakes the painted car grille so that the paint on the outside is initially dried. When the car grille is subsequently taken out, the paint sprayed on the outside is less likely to flow and drip, affecting the spraying effect. If the results of the photo comparison do not meet the preset requirements, it may be that there are impurities attached to the car grille to be sprayed or that the debris left over from the previous production process has not been cleaned up. Direct spraying will affect the overall quality of the subsequent car grille and the spraying effect will be adversely affected. At this time, the rotating seat 18 can be used to drive the gas nozzle 14 toward the car grille to be sprayed. The gas nozzle 14 blows gas to the car grille to blow and clean the impurities and residual debris attached to the outside of the car grille. After cleaning, the paint spray head 22 is turned again to the car grille to be sprayed, and the camera 40 is used to take another picture of the car grille for comparison. If the comparison result is satisfactory, the car grille is sprayed according to the above spraying steps. If the comparison result is still unsatisfactory, the car grille is not sprayed and is removed for repair. This ensures that the car grille is in a qualified state before spraying, and avoids the situation where a defective car grille or a car grille with impurities on the outside is sprayed and cannot be used after spraying, which will bring difficulties to the subsequent repair of the car grille and waste paint.

[0044] Before or during spraying, in order to test whether the paint sprayed from the paint nozzle 22 is uniform, the main shaft 7 can be rotated to drive the test plate 8 to rotate toward the paint nozzle 22, and the paint nozzle 22 can be sprayed onto the test plate 8 in the same manner as spraying a car grille. After the test plate 8 is sprayed, the heating plate 36 below the second horizontal plate 11 can be used to heat and dry the paint on the test plate 8. The heating plate 36 is then moved away from the test plate 8 as the first connecting rod 12 rotates. The first horizontal plate 10 is moved above the test plate 8 by the rotation of the first connecting rod 12, and then the first telescopic rod 33 is retracted, driving the first horizontal plate 10 and the multiple paint film meters 37 below it to move downward until the detection head of the paint film meter 37 contacts the sprayed surface of the test plate 8. The values ​​measured by the multiple paint film meters 37 are read, and the uniformity of the paint spray thickness is determined based on the measured values. If the difference in the values ​​measured by the multiple paint film meters 37 is greater than the preset error range, it means that the paint spray head 22 is not sprayed uniformly and needs to be repaired and maintained to avoid uneven spraying when spraying the car grille in the future.

[0045] If the paint spraying detected on the test plate 8 is relatively uniform, it means that the paint spray head 22 can be used for normal spraying. At this time, the test plate 8 can be rotated to the top of the base plate 25 using the main shaft 7, and then the second telescopic rod 42 drives the polishing plate 27 to move upward until the polishing plate 27 contacts the spraying surface of the test plate 8. The polishing plate 27 uses the fourth slider 43 at the bottom to move back and forth in the second slide 26, thereby performing a friction test on the spraying surface of the test plate 8. Different polishing plates 27 can be used according to the test requirements, and the pressure between the polishing plate 27 and the spraying surface of the test plate 8 can be adjusted to check the wear resistance of the spraying surface. Then, it is analyzed and judged whether the thickness and spraying method of the paint spraying meet the preset usage requirements, which facilitates the staff to adjust the working mode of the paint spray head 22 so that the car grille can achieve the best effect when spraying.

[0046] The spraying equipment is easy to operate and can be used to spray different car grilles. It can also test the spraying effect at any time before and during spraying, avoiding the failure to detect problems with the spraying components in time, resulting in a large number of car grilles being unqualified after spraying. At the same time, it can also inspect the car grilles before spraying, avoiding the waste of paint and coatings caused by the spraying of defective car grilles. It also prevents the repair process of the car grilles after spraying from being affected by the external paint.
