Description

Technical Field

[0001] The present application relates to the field of bumper production technology, and in particular to a bumper forming device and process thereof. Background Art

[0002] A bumper is a safety device installed at the front or rear of a car to prevent damage to the car in a collision and to protect the safety of the car and the people inside.

[0003] Currently, the bumper molding process typically involves multiple steps, including injection molding, polishing, painting, and drying, to create a smooth, aesthetically pleasing bumper. During the painting process, the bumper itself is moved onto a support frame, and a multi-axis robot drives the spray nozzle to move the paint onto the bumper.

[0004] During the bumper painting process, some of the dispersed paint tends to spill and accumulate on the support stand. During batch painting of the bumper body, the bottom surface of the bumper body placed on the support stand tends to adhere to the residual paint on the stand. When the bumper bottom is subsequently painted, the paint will accumulate on the surface of the residual paint adhered to the bumper body, resulting in uneven coating thickness. Furthermore, during the bumper painting process, the paint sprayed on the bumper surface tends to adhere to the paint sprayed on the support stand. When the finished bumper is subsequently removed, the paint layer between the bumper and the support stand tends to crack, resulting in a poorly finished bumper surface. Summary of the Invention

[0005] In order to improve the problem of poor paint spraying quality on the bumper surface, the present application provides a bumper forming device and a process thereof.

[0006] The bumper forming device provided in this application adopts the following technical solution:

[0007] A bumper forming device includes a frame, wherein the frame is provided with:

[0008] Processing platform: used to place the bumper body to be processed;

[0009] Support mechanism: performing adsorption support on the bottom of the bumper body at the processing platform and separating the bumper body from the processing platform;

[0010] Pressing assembly: used for pressing the bumper body delivered to the processing platform toward the adsorption end of the support mechanism;

[0011] Spraying mechanism: used for spraying and molding the bumper body on the processing platform.

[0012] By adopting the above technical solution, during the forming process of the bumper, the bumper body is flexibly supported on the processing platform by the support mechanism, so that the lower peripheral edge of the bumper body no longer contacts the processing platform, and then the pressing assembly presses the bumper body toward the support mechanism, so that the support mechanism adsorbs and positions the bumper body, thereby achieving stable installation of the bumper body; then the pressing assembly is away from the bumper body, and the spraying mechanism paints and forms the bumper body on the processing platform; during the painting process, since the bumper body is separated from the upper end surface of the processing platform under the support of the support mechanism, the paint falling onto the processing platform is not easy to adhere to the paint sprayed on the surface of the bumper body, thereby effectively improving the paint spraying quality of the bumper surface.

[0013] Optionally, the support mechanism includes two positioning columns arranged at intervals on the processing platform, a flexible support strip arranged above the two positioning columns, and an adsorption component arranged in the middle of the flexible support strip and used to adsorb and position the bumper body; an adjustment component is provided between the two positioning columns and the flexible support strip for bending the flexible support strip so that the two ends of the flexible support strip in the length direction are higher or lower than the adsorption end of the adsorption component.

[0014] By adopting the above technical solution, when in use, the two ends of the flexible support strip in the length direction support the bumper body, and then the bending curvature of the flexible support strip is adjusted by the adjustment component, so that the two ends of the flexible support strip in the length direction are gradually lower than the adsorption part, and then while the flexible support strip continues to support the bumper, the adsorption part adsorbs and fixes the bumper body, thereby achieving stable installation of the bumper body.

[0015] Optionally, the adjustment assembly includes a guide column fixed on the positioning column, two guide rings spaced apart at the bottom sides of both ends of the flexible support bar in the length direction, and an elastic member for elastically connecting the middle part of the flexible support bar and the processing platform, and the guide column is slidably installed in the guide ring along the extension direction of the flexible support bar.

[0016] By adopting the above technical solution, the elastic member is provided to elastically connect the middle part of the support strip to the processing platform, and the two ends of the flexible support strip in the length direction are slidably supported on the positioning column through the guide ring and the guide column; when the bow-shaped flexible support strip is subjected to pressure from above, the two ends of the flexible support strip in the length direction are compressed and move tilted downward under the cooperation of the guide column and the guide ring; at the same time, the middle part of the flexible support strip is lifted by the pull of the two ends of the flexible support strip in the length direction, so that the adsorption part in the middle part of the flexible support strip actively approaches the bumper body, thereby facilitating the adsorption end of the adsorption part to perform the adsorption operation of the bumper body.

[0017] Optionally, a plurality of the flexible support strips are provided on the processing platform, and a plurality of positioning columns and guide columns are correspondingly provided on the processing platform. The plurality of the flexible support strips are cross-arranged, and the middle portions of the plurality of flexible support strips are interconnected.

[0018] By adopting the above technical solution, multiple flexible support strips arranged in a cross shape support the bumper body at multiple points, thereby improving the support stability of the bumper body; and since the bumper body itself is multi-curved, when supporting the bumper body, each end of the multiple flexible support strips respectively supports the inner side of the lower end of the bumper body, and the flexible support strips are compressed and bent along the curved inner wall of the bumper body according to their own flexibility; after the multiple flexible support strips are compressed and bent, they drive the adsorption part to adsorb and position the lower inner wall of the bumper body, thereby realizing flexible installation and positioning of the bumper body, ensuring the stable installation of the bumper body, and avoiding the occurrence of bumper body being easily bumped and scratched during conventional installation and positioning.

[0019] Optionally, an elastic filter cover is provided on the processing platform, and a filter cavity for filtering air for the adsorption component is formed between the elastic filter cover, the multiple flexible support bars and the workpiece body.

[0020] By adopting the above technical solution, when the adsorption member is performing adsorption and positioning of the bumper body, the air sucked by the adsorption member is filtered through the elastic filter cover on the periphery, so that impurities and paint mist dispersed in the air are not easily sucked into the adsorption member.

[0021] Optionally, both ends of the flexible support strip in the length direction are bent toward the processing platform.

[0022] By adopting the above technical solution, the two ends of the flexible support strip in the length direction are bent, so that when the flexible support strip is under pressure, the two ends of the flexible support strip in the length direction are opened in the direction away from the middle of the flexible support strip, thereby smoothly realizing the compressive support of the bumper body by the flexible support strip.

[0023] Optionally, the positioning column includes a cylindrical portion fixed on the processing platform, a positioning portion slidably arranged on the cylindrical section along the height direction, and a locking portion for locking or releasing the positioning portion on the cylindrical portion.

[0024] By adopting the above technical solution, the staff adjusts the positioning part inside the cylinder part and locks the positioning part in the desired position through the locking part to adjust the overall length of the positioning column, adjust the initial bending curvature of the flexible support strip and adjust the support height of the bumper body.

[0025] Optionally, the pressing assembly includes a plurality of linear driving members arranged on the frame and a pressing block fixed at the output end of the linear driving member, and the linear driving member is used to drive the pressing block to move and press down the bumper body at the support mechanism.

[0026] By adopting the above technical solution, after the bumper body is placed on the upper end of the flexible support strip, the pressure block is driven to move by the linear drive member, and the bumper body can be pressed by the moving pressure block to actively apply pressure through the top of the bumper body, making it easier for the support structure to adsorb and fix the bumper body.

[0027] Optionally, a plurality of processing platforms are spaced apart on the frame, and a driving component for adjusting the spacing between the plurality of processing platforms is provided on the frame.

[0028] By adopting the above-mentioned technical solution, multiple processing platforms are set up to jointly support the bumper body, so that the support of the bumper body is more stable; and the spacing between the multiple processing platforms is adjusted by the driving component, so that the multiple processing platforms are suitable for the installation and positioning of bumper bodies of various models or specifications, thereby improving the versatility of the device.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The support mechanism flexibly supports the bumper body on the processing platform, so that the lower peripheral edge of the bumper body no longer contacts the processing platform. The pressing assembly then presses the bumper body toward the support mechanism, allowing the support mechanism to absorb and position the bumper body, achieving stable installation of the bumper body. During the painting process, because the bumper body is separated from the upper end surface of the processing platform by the support mechanism, paint that falls onto the processing platform is less likely to adhere to the paint sprayed on the bumper body surface, thereby improving the paint spray quality of the bumper surface.

[0031] 2. The flexible support strip supports the bumper body at both ends along its length. The bending curvature of the flexible support strip is then adjusted using an adjustment assembly so that both ends of the flexible support strip gradually become lower than the adsorption member. While the flexible support strip maintains support for the bumper, the adsorption member adsorbs and secures the bumper body, thereby achieving stable installation of the bumper body.

[0032] 3. When the adsorption component is adsorbing and positioning the bumper body, the air sucked by the adsorption component is filtered through the elastic filter cover on the periphery, so that impurities and paint mist dispersed in the air are not easily sucked into the adsorption component.

[0038] The following is combined with Figure 1-4 This application is described in further detail.

[0039] The embodiment of the present application discloses a bumper forming device. Figure 1 The bumper forming device includes a frame 1 and a construction seat 11 slidably arranged on the frame 1, and a plurality of processing platforms 2 and a driving assembly 3 for adjusting the distance between the plurality of processing platforms 2 are arranged on the construction seat 11. A support mechanism 4 for flexibly lifting and adsorbing the inner side of the bottom of the bumper body is provided on the processing platform 2, and a pressing assembly 5 for pressing the bumper body toward the adsorption end of the support mechanism 4 is provided above the plurality of processing platforms 2 on the frame 1. A spraying mechanism 6 for spraying and shaping the bumper body on the processing platform 2 is provided on one side of the construction seat 11 on the frame 1, and a conveying mechanism 7 for conveying the bumper body to the processing platform 2 is provided on the other side of the construction seat 11 on the frame 1. The spraying mechanism 6 and the conveying mechanism 7 are prior art and will not be described in detail here.

[0040] Reference Figure 1 and Figure 2The support mechanism 4 includes four positioning posts 41, two flexible support bars 42, and an adjustment assembly. The four positioning posts 41 are arranged in a matrix on the upper surface of the processing platform 2. The two flexible support bars 42 are arranged in a cross-section at the center. The two ends of the flexible support bars 42 are bent toward the processing platform 2. A suction member 43 is provided at the intersection of the two flexible support bars 42. The suction end of the suction member 43 faces upward. The suction member 43 can be any of a vacuum suction cup, a suction head, a rubber nozzle, etc., as long as it can stably absorb the bumper body.

[0041] In this embodiment, every two positioning posts 41 correspond to one flexible support strip 42, and an adjustment assembly is disposed between the positioning posts 41 and the flexible support strip 42. The adjustment assembly is used to bend the flexible support strip 42 so that both ends of the flexible support strip 42 along its length are higher or lower than the adsorption end of the adsorption member 43. In other embodiments, the number of flexible support strips 42 can also be three, four, etc., and the number of positioning posts 41 is correspondingly set to twice the number of flexible support strips 42.

[0042] Reference Figure 2 and Figure 3 The adjustment assembly includes a guide post 44 fixed horizontally to the positioning post 41, two guide rings 45 spaced apart at the bottom sides of the flexible support strip 42 along its length, and an elastic member 46 for elastically connecting the middle portion of the flexible support strip 42 and the upper end surface of the processing platform 2. The guide post 44 is slidably mounted within the guide ring 45 along the extension direction of the flexible support strip 42. The elastic member 46 can be a spring or a spring plate, and in this embodiment, the elastic member 46 is preferably a spring.

[0043] During use, when the bow-shaped flexible support strip 42 is subjected to pressure from above, the two ends of the flexible support strip 42 in the length direction are compressed and move downward in an open state with the cooperation of the guide column 44 and the guide ring 45; at the same time, the middle part of the flexible support strip 42 is lifted by the pull of the two ends of the flexible support strip 42 in the length direction, so that the adsorption part 43 in the middle part of the flexible support strip 42 actively approaches the bumper body, thereby facilitating the adsorption end of the adsorption part 43 to perform the adsorption operation of the bumper body.

[0044] Reference Figure 2 and Figure 3To prevent impurities such as airborne impurities and paint mist from being drawn into the adsorbent 43 during its adsorption process, the processing platform 2 is equipped with an elastic filter cover 21, which is interconnected with a plurality of flexible support strips 42. The elastic filter cover 21 is made of a highly elastic, tear-resistant, and breathable fabric. During use, when the bumper rests on the flexible support strips 42, the edges of the elastic filter cover 21 and the flexible support strips 42 adhere to the bumper surface, creating a filter cavity between the elastic filter cover 21, the multiple flexible support strips 42, and the bumper surface for air filtration by the adsorbent 43, ensuring the normal and stable operation of the adsorbent 43.

[0045] Reference Figure 2 and Figure 3 Since the bumper body itself has a multi-curved shape, when supporting the bumper body, in order to make the ends of the multiple flexible support strips 42 stably fit the inner arc surface of the lower end of the bumper body, the positioning column 41 is set to a height-adjustable telescopic rod structure to adjust the flexible support strips 42 to a suitable initial bending state.

[0046] Specifically, the positioning column 41 includes a cylindrical portion 411 fixed to the upper end surface of the processing platform 2, a positioning portion 412 slidably provided on the cylindrical portion along the height direction, and a locking portion 413 for locking or releasing the positioning portion 412 on the cylindrical portion 411. In this embodiment, the positioning portion 412 is cylindrical and has a plurality of positioning holes spaced apart on its circumference, while the cylindrical portion 411 has a plurality of corresponding threaded holes on its circumference. The locking portion 413 is in the shape of a rod with threads on its outer circumference, and the external threads on the locking portion 413 mate with the internal threads of the threaded holes, and the head of the locking portion 413 is pluggable and fits into the positioning holes.

[0047] In another embodiment, the positioning column 41 includes a cylindrical portion fixed on the processing platform 2 and a column portion slidably arranged on the cylindrical portion along the height direction, and a connecting spring is provided between the bottom surface of the cylindrical portion and the column portion to connect the two.

[0048] Reference Figure 4 To facilitate the rapid adsorption of the bumper body by the adsorption member 43, the pressing assembly 5 includes a plurality of linear drive members 51 and a pressure block 52 fixed to the output end of the linear drive member 51. The linear drive member 51 is fixed to the frame 1 or the construction base 11. The linear drive member 51 drives the pressure block 52 to move toward the processing platform 2. The pressure block 52 is arranged with an inclined surface on the lower side of one end facing the processing platform 2. During use, after the bumper body is placed on the plurality of flexible support bars 42, the linear drive member 51 drives the pressure block 52 to move in a direction closer to the processing platform 2, so that the pressure block 52 presses the upper end of the bumper body, causing the bumper body to be pressed downward and close to the adsorption member 43.

[0049] Reference Figure 1 The drive assembly 3 includes a bidirectional threaded rod 31, a drive motor 32, and a guide rod 33. The bidirectional threaded rod 31 is rotatably mounted on the construction seat 11. The threads at both ends of the bidirectional threaded rod 31 in the length direction are in opposite directions, and the threads at both ends of the bidirectional threaded rod 31 in the length direction penetrate the two processing platforms 2 one by one. The guide rod 33 is arranged side by side and flush with the bidirectional threaded rod 31, and the guide rod 33 is fixedly mounted on the construction seat 11. The guide rod 33 penetrates the two processing platforms 2 along the length direction of the bidirectional threaded rod 31. The drive motor 32 is mounted on the construction platform, and the output shaft of the drive motor 32 is coaxially fixed to one end of the bidirectional threaded rod 31. When in use, the drive motor 32 drives the bidirectional threaded rod 31 to rotate, and then the rotating bidirectional threaded rod 31 drives the two processing platforms 2 to move closer to or away from each other, so as to adjust the distance between the two processing platforms 2, so that the device is suitable for the installation and positioning of bumper bodies of different sizes.

[0050] Furthermore, a linear motor 12 is fixedly mounted on the frame 1, and the construction seat 11 is fixedly mounted on the slide of the linear motor 12. The slide of the linear motor 12 slides back and forth in the direction from the spraying mechanism 6 to the conveying mechanism 7, so that after the bumper body is installed on the support mechanism 4 on the processing platform 2, the linear motor 12 drives the processing platform 2 to move quickly to the spraying mechanism 6, thereby realizing the position distinction between the bumper spraying area and the bumper installation area.

[0051] The bumper forming device and process according to the present embodiment are implemented as follows: During use, a conveying mechanism 7 conveys the initially formed bumper body to be painted onto a processing platform 2. A supporting mechanism 4 then flexibly supports the bumper body above the processing platform 2, ensuring that the lower peripheral edge of the bumper body no longer contacts the processing platform 2. A pressing assembly 5 then presses the bumper body toward the supporting mechanism 4, allowing the supporting mechanism 4 to absorb and position the bumper body, achieving stable installation of the bumper body. A linear motor 12 then conveys the processing platform 2 to the spraying mechanism 6, which then sprays the bumper body with stable paint.

[0052] The present application also discloses a bumper forming process, which includes the following steps:

[0053] S1: transport the bumper body to the support mechanism 4 on the processing platform 2;

[0054] S2: The pressing assembly 5 presses the bumper body on the support mechanism 4, and the bottom of the bumper body is adsorbed and positioned by the adsorption member 43;

[0055] S3: The spraying mechanism 6 sprays paint on the bumper body on the supporting mechanism 4;

[0056] S4: Drying the paint on the painted bumper body.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
