Description

Technical Field

[0001] This utility model belongs to the field of automotive guard plate spraying technology, and in particular relates to a multi-angle spraying equipment for automotive guard plates. Background Technology

[0002] Multi-angle skid plates are protective components installed on critical areas such as the underside and side skirts of a vehicle. They are not a single flat surface, but a three-dimensional structure composed of multiple complex curved and folded surfaces. These plates act like "armor" for the car's chassis, primarily serving to resist impacts from sand and gravel, prevent scraping and abrasion, and optimize underbody aerodynamics. Due to their unique function and installation location, they are exposed to impacts and wear from almost every direction; therefore, their design encompasses the windward side, sides, bottom, and various connecting and fixing structures, forming a comprehensive protection system.

[0003] For complex components like multi-angle protective plates, the industry commonly employs a combination of automated robotic painting systems and manual touch-up painting. First, the protective plate is transported to a closed painting chamber via a suspended chain. A multi-axis robot, with its flexible "arm" and pre-programmed trajectory, rotates 360 degrees around the workpiece to ensure precise and even paint coverage of every exposed curved surface and edge. For internal grooves or narrow crevices that are difficult for the robot to reach, experienced workers perform targeted manual touch-up painting at subsequent stations. Throughout the process, specialized plastic coatings with strong adhesion and good corrosion resistance are typically used, and electrostatic spraying is employed to improve paint utilization and coverage uniformity.

[0004] The existing automated processing equipment is expensive and not conducive to small-batch production, while the efficiency of purely manual processing is poor and it is difficult to stably flip the guard plate from multiple sides.

[0005] To address the aforementioned issues, this application proposes a multi-angle spraying device for automotive protective panels. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-angle spraying equipment for automotive protective panels, which features simple operation, high spraying efficiency, and high workpiece stability.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a multi-angle spraying device for automotive protective panels, comprising a C-shaped frame and side clamps. The C-shaped frame and side clamps are synchronously rotatably connected to two fixed seats. The C-shaped frame includes a side clamp, a backing plate, and a support plate. A first support plate is fixed at the bottom of the angle between the side clamp and the backing plate. A gap is formed between the first support plate and the side clamp and the backing plate for installing the front end of the skirt and inserting it on one side. The side clamp is horizontally slidably connected to the side of the C-shaped frame. A second support plate corresponding to the first support plate is fixed on the side clamp. A gap is formed between the second support plate and the backing plate and the side clamp for installing the front end of the skirt and inserting it on the other side. The gaps between the first support plate, the second support plate, the side clamp, the backing plate, and the side clamp correspond to the thickness of the skirt installed on the multi-angle protective panel.

[0009] Furthermore, a guide sleeve is fixed on the support plate, and a guide rod is fixed on the side clamp plate and slidably connected to the guide sleeve.

[0010] Furthermore, an ejector block is fixed to the end of the guide rod away from the side clamp, and a slot for the ejector block to move is provided in the first support plate. The moving path of the ejector block at least partially coincides with the gap formed by the side clamp and the first support plate.

[0011] Furthermore, the side clamp is fixed with a guide hole that communicates with the first support plate, and the ejector block is also slidably connected to the guide hole.

[0012] Furthermore, a drive shaft is fixed at one end of the C-shaped frame away from the side clamp, and the drive shaft is rotatably connected to a fixed seat at one end. A servo motor that drives the drive shaft and the C-shaped frame is fixed on the fixed seat.

[0013] Furthermore, a splined shaft is fixed to one end of the side clamp away from the C-shaped frame, and a splined sleeve is rotatably connected to the fixed seat at the other end, which slides axially with the splined shaft.

[0014] Furthermore, an electric cylinder is fixed to the side of the support plate, and the output end of the electric cylinder is fixedly installed with the side clamping plate.

[0015] This utility model has the following beneficial effects:

[0016] This utility model fixes the fixed seat on the sliding seat at the bottom of the planar reciprocating sprayer to form a spraying device. The planar reciprocating sprayer can realize three-axis movement, and then the C-shaped frame and side clamps drive the multi-angle guard plate to rotate to realize four-axis movement, thereby achieving multi-sided stable spraying of the guard plate in a low-cost manner.

[0017] This utility model can pre-position the multi-angle guard plate by the cooperation of the abutment plate and the first support plate, and then quickly fix the multi-angle guard plate by the installation skirt under the push of the side clamp plate. Then, under the drive of the servo motor, the multi-angle guard plate can be stably sprayed on multiple sides.

[0018] This utility model, by setting an ejector block on the guide rod to cooperate with the guide hole, can eject the mounting skirt from between the side clamp and the first support plate when the side clamp is released from the clamp of the multi-angle guard plate, thereby facilitating the removal of the multi-angle guard plate after spraying.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1 - Figure 6 As shown, this utility model is a multi-angle spraying device for automotive protective panels, including a C-shaped frame 1 and a side clamp 2. The C-shaped frame 1 and the side clamp 2 are synchronously rotatably connected to two fixed seats 4. The C-shaped frame 1 includes a side clamp 11, a back plate 12, and a support plate 14. A first support plate 13 is fixed at the bottom of the angle between the side clamp 11 and the back plate 12. A gap is formed between the first support plate 13 and the side clamp 11 and the back plate 12 for installing the front end and one side of the skirt 61.

[0032] The side clamp 2 is horizontally slidably connected to the side of the C-shaped frame 1. A second support plate 21 corresponding to the first support plate 13 is fixed on the side clamp 2. A gap is formed between the second support plate 21, the abutment plate 12, and the side clamp 2 for installing the front end of the skirt 61 and inserting it on the other side. In this embodiment, the first support plate 13 and the second support plate 21 can play a supporting role before and after positioning the multi-angle guard plate 6.

[0033] Furthermore, the gaps between the first support plate 13, the second support plate 21 and the side clamp 11, the abutment plate 12, and the side clamp 2 correspond to the thickness of the skirt 61 installed on the multi-angle guard plate 6. In this embodiment, the gap only serves to limit the installation skirt 61 and will not form an interference fit or compression. Therefore, the installation skirt 61 can easily move in the gap when it is not clamped.

[0034] Furthermore, in order to ensure the sliding stability of the side clamp 2 on the side of the C-shaped frame 1, a guide sleeve 141 is fixed on the support plate 14, and a guide rod 22 is fixed on the side clamp 2 and slidably connected to the guide sleeve 141; in this embodiment, at least two sets of guide sleeve 141 and guide rod 22 are provided and symmetrically arranged between the C-shaped frame 1 and the side clamp 2.

[0035] Furthermore, an ejector block 23 is fixed to the end of the guide rod 22 away from the side clamping plate 2. A slot for the ejector block 23 to move is provided in the first support plate 13. The moving path of the ejector block 23 at least partially coincides with the gap formed by the side clamping seat 11 and the first support plate 13. When the mounting skirt 61 enters the gap between the side clamping seat 11 and the first support plate 13, the ejector block 23 is driven by the electric cylinder 3 to exit from the overlapping part to the side, ensuring the stable clamping of the multi-angle guard plate 6. When the electric cylinder 3 drives the side clamping plate 2 to disengage from the C-shaped frame 1 from the clamping of the multi-angle guard plate 6, the ejector block 23 is pulled by the electric cylinder 3 and enters the gap between the side clamping seat 11 and the first support plate 13, thereby ejecting the internal mounting skirt 61 to the side.

[0036] Furthermore, the side clamp 11 is fixed with a guide hole 111 that communicates with the first support plate 13, and the ejector block 23 is also slidably connected to the guide hole 111; in this embodiment, the guide hole 111 stabilizes the movement path of the ejector block 23, ensuring that the mounting skirt 61 can be pushed out of the gap between the side clamp 11 and the first support plate 13, thereby facilitating the removal of the multi-angle guard plate 6.

[0037] Furthermore, a drive shaft 112 is fixed at the end of the C-shaped frame 1 away from the side clamping plate 2. The drive shaft 112 is rotatably connected to a fixed base 4 at one end. A servo motor 5 that drives the drive shaft 112 and the C-shaped frame 1 is fixed on the fixed base 4. In this embodiment, the servo motor 5 works in cooperation with a controller and a motor starter. The servo motor 5 drives the rotation of the C-shaped frame 1, the side clamping plate 2 and the multi-angle protective plate 6, thereby changing the spraying surface of the multi-angle protective plate 6 and thus realizing multi-sided spraying of the multi-angle protective plate 6.

[0038] Furthermore, in order to ensure both the rotatable connection between the side clamp 2 and the fixed seat 4 and the sliding fit between the side clamp 2 and the C-shaped frame 1, a spline shaft 24 is fixed at one end of the side clamp 2 away from the C-shaped frame 1, and a spline sleeve 41 is rotatably connected to the fixed seat 4 at the other end, which is axially slidingly fitted with the spline shaft 24. In this embodiment, the sliding fit length between the spline sleeve 41 and the spline shaft 24 is greater than the sliding length between the side clamp 2 and the C-shaped frame 1.

[0039] Furthermore, an electric cylinder 3 is fixed to the side of the support plate 14. The output end of the electric cylinder 3 is fixedly installed with the side clamping plate 2. Through the operation of the electric cylinder 3, the side clamping plate 2 is driven to move horizontally on the C-shaped frame 1. While the side clamping plate 2 is moving, the second support plate 21, guide rod 22 and ejector block 23 move synchronously.

[0040] Understandably, this invention provides a low-cost four-axis spraying device. It achieves three-axis motion by mounting the fixed base on the sliding seat of a planar reciprocating sprayer, and forms a fourth axis motion by using a C-shaped frame and side clamps to rotate the multi-angle guard plate, thus achieving stable multi-faceted spraying of the guard plate. The guard plate is pre-positioned using a backing plate and a first support plate, and then quickly fixed by the side clamps pushing the mounting skirt. After spraying, when the side clamps are released, the ejector block on the guide rod automatically pushes the mounting skirt out from between the side clamp and the first support plate, facilitating the removal of the guard plate.

[0041] One specific application of this embodiment is as follows: Figure 2 With the mechanism in the open state, the multi-angle guard plate 6 is placed on the first support plate 13 and the second support plate 21 and pushed forward, so that the front mounting skirt 61 is inserted into the gap formed by the abutment plate 12 and the first support plate 13 and the second support plate 21; the electric cylinder 3 is activated to drive the side clamping plate 2 to move towards the C-shaped frame 1, and the entire side clamping plate 2 moves synchronously. The ejector block 23 moves from the gap between the side clamping seat 11 and the first support plate 13 into the guide hole 111. After the side clamping plate 2 is pushed, the two sides of the mounting skirt 61 are respectively inserted into the gaps between the side clamping seat 11, the first support plate 13 and the side clamping plate 2 and the second support plate 21, which is the... Figure 5 As shown, the multi-angle guard plate 6 is clamped and fixed at this time; the flat reciprocating sprayer sprays the top surface of the multi-angle guard plate 6. After the top surface is sprayed, the C-shaped frame 1, the side clamping plate 2, and the multi-angle guard plate 6 are rotated by the servo motor 5 to rotate the unsprayed surface to the top. Then, the surface is also sprayed under the operation of the flat reciprocating sprayer to realize the multi-sided spraying work.

[0042] After the spraying is completed, the electric cylinder 3 works in reverse. One side of the skirt 61 is disengaged from the gap between the side clamp 2 and the second support plate 21. As the side clamp 2 moves outward, the ejector block 23 moves into the gap between the side clamp 11 and the first support plate 13. The ejector block 23 disengages the other side of the skirt 61 from the gap between the side clamp 11 and the first support plate 13. Then, the worker pulls the multi-angle guard plate 6 backward so that the front end of the skirt 61 is disengaged from the gap between the abutment plate 12 and the first support plate 13 and the second support plate 21, and the sprayed multi-angle guard plate 6 can be removed.
