Description

Technical Field

[0001] This application relates to the field of bumper manufacturing technology, specifically to a spraying equipment for bumper manufacturing. Background Technology

[0002] Car bumpers are safety devices that absorb and mitigate external impacts, protecting the front and rear of the vehicle. With the development of the automotive industry and the widespread use of engineering plastics, car bumpers, as an important safety device, have also undergone innovation. Today's car bumpers, in addition to maintaining their original protective function, also strive for harmony and unity with the vehicle's design, and aim for lightweight construction. Both front and rear bumpers are made of plastic. During the production process, a layer of paint matching the car's body color is sprayed onto the outer side of the bumper, making the combination between the car body and the bumper more aesthetically pleasing.

[0003] Therefore, a layer of paint matching the car body color can be sprayed onto the outside of the bumper using bumper painting equipment. However, when painting the bumper, the equipment does not have a stable clamping and fixing mechanism to secure it, which may cause the bumper to shift during the painting process, thus affecting the painting effect and quality. In addition, the bumper needs a certain amount of time to air dry after painting. If the bumper is not dried and moved after painting, it can easily affect the painting effect. Utility Model Content

Detailed Implementation

[0024] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0025] Car bumpers are safety devices that absorb and mitigate external impacts, protecting the front and rear of the vehicle. With the development of the automotive industry and the widespread use of engineering plastics, car bumpers, as an important safety device, have also undergone innovation. Today's car bumpers, in addition to maintaining their original protective function, also strive for harmony and unity with the vehicle's design, and aim for lightweight construction. Both front and rear bumpers are made of plastic. During the production process, a layer of paint matching the car's body color is sprayed onto the outer side of the bumper, making the combination between the car body and the bumper more aesthetically pleasing.

[0026] Therefore, a layer of paint matching the car body color can be sprayed onto the outside of the bumper using bumper painting equipment. However, when painting the bumper, the equipment does not have a stable clamping and fixing mechanism to secure it, which may cause the bumper to shift during the painting process, thus affecting the painting effect and quality. In addition, the bumper needs a certain amount of time to air dry after painting. If the bumper is not dried and moved after painting, it can easily affect the painting effect.

[0027] To address the issue of poor paint finish caused by insecurely fixed bumper positions and inability to dry properly during bumper painting. (See also...) Figures 1-4 This application provides a spraying device for bumper production, comprising:

[0028] Workbench 1 is equipped with a receiving box 2 for accommodating bumpers. The receiving box 2 can be pulled out from the workbench 1. After the bumpers are painted and dried, they can be placed into the receiving box 2. When there are a lot of bumpers stored in the receiving box 2, the receiving box 2 can be taken out, the bumpers can be transferred, and the receiving box 2 can be installed back onto the workbench 1.

[0029] A fixed frame 3 is connected to the workbench 1; a top plate is provided at the end of the fixed frame 3 away from the workbench 1, a liquid storage box 7 is connected to the side of the top plate away from the workbench 1, and a mounting bracket 4 is provided on the side of the top plate close to the workbench 1; a hydraulic cylinder 5 passes through the mounting bracket 4 and is connected to the sprayer 6; the sprayer 6 is connected to the liquid storage box 7 through a hose 8.

[0030] The mounting bracket 3 has an n-shaped structure, with its top plate positioned a certain distance from the upper surface of the workbench 1. A liquid reservoir 7 and a sprayer 6 are mounted on the top plate of the mounting bracket 3. The liquid reservoir 7 and the sprayer 6 are connected by a hose 8, allowing the paint stored in the liquid reservoir 7 to be sprayed onto the bumper below the top plate via the sprayer 6. Furthermore, a hydraulic cylinder 5 passes through the mounting bracket 4 and connects to the sprayer 6. By controlling the extension and retraction of the hydraulic cylinder 5, the height of the sprayer 6 can be adjusted to improve the spraying effect and quality of the bumper, preventing poor spraying results due to improper height.

[0031] A clamping and fixing assembly 9 is connected to the worktable 1. The clamping and fixing assembly 9 includes a fixing plate 901. The fixing plate 901 is symmetrically provided with movable grooves 902 along its length. A bidirectional threaded rod 904 is provided in the movable groove 902. Both ends of the bidirectional threaded rod 904 protrude from the fixing plate 901 and are rotatably connected to the fixing plate 901. The same end of the two bidirectional threaded rods 904 is connected by a pulley 905. The end of the bidirectional threaded rod 904 away from the pulley 905 is connected to a first motor 903.

[0032] The clamping components are symmetrically arranged at both ends of the bidirectional threaded rod 904. Rotation of the bidirectional threaded rod 904 causes the clamping components to move closer to or away from the center point. The bidirectional threaded rod 904 is located within a movable groove 902. The threads on either side of the center point of the bidirectional threaded rod 904 are in opposite directions. Clamping components are connected to both ends of the bidirectional threaded rod 904. Rotating the threaded rod 904 causes the clamping components to move closer to or away from the center point. For example, when the bidirectional threaded rod 904 rotates clockwise, the clamping components move towards the center point of the bidirectional threaded rod 904; when the bidirectional threaded rod 904 rotates counterclockwise, the clamping components move away from the center point of the bidirectional threaded rod. When it is necessary to clamp the bumper, the bidirectional threaded rod 904 can be rotated clockwise, causing the clamping components to abut against the bumper and thus fix the clamping components in place.

[0033] Since the same end of the bidirectional threaded rods 904 is connected via pulley 905, when one of the bidirectional threaded rods 904 rotates, it will drive the pulley 905 to rotate, which in turn drives the other bidirectional threaded rod 904 to rotate. Therefore, a first motor 903 can be connected to the end of one of the bidirectional threaded rods 904 away from the pulley 905. When the first motor 903 is started, it will simultaneously drive both bidirectional threaded rods 904 to rotate in the same direction, thereby moving the clamping assembly. By placing the bumper between the two clamping assemblies and starting the first motor 903 to move the clamping assembly, the bumper is fixed in place, preventing its position from changing during the painting process and improving the effect and quality of the painting operation.

[0034] The drying assembly 10 is connected to the worktable 1 and is located on one side of the clamping and fixing assembly 9. By setting up the drying assembly 10, the paint on the surface of the bumper is dried after the bumper painting operation is completed, which further improves the painting effect and facilitates subsequent processing of the bumper, thereby improving work efficiency.

[0035] In some embodiments, the clamping assembly includes a clamping plate 907 and a threaded slider 906. The threaded slider 906 has a threaded hole in its center, and a bidirectional threaded rod 904 passes through the threaded hole and connects to the threaded slider 906. The clamping plate 907 is fixedly connected to the threaded slider 906. Specifically, one clamping plate 907 corresponds to two threaded sliders 906, and the two threaded sliders 906 are respectively connected to two bidirectional threaded rods 904, with the threaded sliders 906 positioned at the same level as the bidirectional threaded rods 904.

[0036] In some embodiments, the clamping plates 907 are provided with positioning grooves 908, and the two clamping plates 907 are arranged opposite each other on one side of the side with the positioning grooves 908. By providing positioning grooves 908, it is convenient to position the bumper through the positioning grooves 908. For example, the protruding structure on the edge of the bumper is aligned with the positioning groove 908. When the clamping plates 907 move towards each other, the protruding structure is embedded in the positioning groove 908, which can fix the bumper and prevent the position of the bumper from changing due to external force, thus affecting the spraying effect.

[0037] In some embodiments, the drying assembly 10 includes a mounting plate 101, which is disposed on one side of the workbench 1. The horizontal height of the mounting plate 101 is the same as the horizontal height of the upper surface of the workbench 1. A connecting plate 104 is disposed on the side of the mounting plate 101 away from the workbench 1. The connecting plate 104 is perpendicular to the mounting plate 101. The output end of the second motor 105 passes through the mounting plate 101 and is connected to the fan blade 107. A fixing block 102 and a heating tube 103 are disposed on the side of the mounting plate 101 close to the workbench 1. The heating tube 103 is disposed between the two fixing blocks 102.

[0038] In use, the bumper is placed between the two clamping plates 907 and positioned by the positioning groove 908. The first motor 903 is started, driving the bidirectional threaded rod 904 to rotate. Due to the linkage of the pulley 905, the two bidirectional threaded rods 904 rotate simultaneously in the same direction. The threaded slider 906 moves within the movable groove 902, simultaneously moving the two clamping plates 907. The two clamping plates 907 move closer together to clamp and fix the bumper. After the hydraulic cylinder 5 is started and the sprayer 6 is adjusted to a suitable height, the paint is dispensed from the reservoir 7 through the hose 8. The air is fed to the sprayer 6, which is then started to perform the spraying operation. After the spraying operation, the heating tube 103 is turned on to heat the surrounding air, and the second motor 105 is started to drive the fan blade 107 to rotate. The fan blade 107 blows the hot air around the heating tube 103 onto the bumper to dry the paint on the bumper. Once the paint on the bumper surface is dried, the bumper can be placed into the container to complete the paint drying operation on the bumper. This solves the problem of poor paint effect caused by the bumper not being firmly fixed in position and not being able to dry in time during the bumper spraying process.

[0039] As can be seen from the above technical solutions, this application provides a painting equipment for bumper production, including: a workbench 1, the workbench 1 being provided with a receiving box 2 for accommodating bumpers; a fixing frame 3, the fixing frame 3 being connected to the workbench 1; a top plate being provided at the end of the fixing frame 3 away from the workbench 1, a liquid storage box 7 being connected to the side of the top plate away from the workbench 1, and a mounting frame 4 being provided on the side of the top plate close to the workbench 1; a hydraulic cylinder 5, the hydraulic cylinder 5 passing through the mounting frame 4 and connected to a sprayer 6; the sprayer 6 being connected to the liquid storage box 7 via a hose 8; and a clamping and fixing assembly 9, the clamping and fixing assembly 9 being connected to the workbench 1; the clamping and fixing assembly 9 including a fixing plate 901; the fixing plate 901 along... A movable groove 902 is symmetrically arranged along its length. A bidirectional threaded rod 904 is disposed within the movable groove 902, with both ends of the bidirectional threaded rod 904 protruding from the fixed plate 901 and rotatably connected to the fixed plate 901. The same end of the two bidirectional threaded rods 904 is connected via a pulley 905. A first motor 903 is connected to the end of the bidirectional threaded rod 904 away from the pulley 905. A clamping assembly is symmetrically arranged at both ends of the bidirectional threaded rod 904; rotation of the bidirectional threaded rod 904 causes the clamping assembly to move closer to or away from the worktable 1. A drying assembly 10 is connected to the worktable 1 and is located on one side of the clamping and fixing assembly 9. By setting the clamping and fixing assembly 9 to fix the bumper, the height of the sprayer 6 is adjusted by controlling the hydraulic cylinder 5 to spray the bumper. After spraying the bumper, the paint on the outer surface of the bumper is dried by the drying device, thus solving the problem of poor spraying effect caused by the bumper not being firmly fixed and not drying in time during the spraying process.
