Abstract
Description
- The present invention relates to a spray nozzle for coating a vehicle flange and a method for coating a vehicle with glue.
- In the industry of vehicle manufacture, an important item in the vehicle coating process is "gluing". The gluing process usually comprises a seam sealing step and an underbody protecting step, so that especially the sealing and the anti-corrosion treatment for vehicles can be achieved, and thus for example the wax can be prevented from discharging from the welding seam in the later step of wax injection in hollow cavity.
- In order to improve the airtightness, the sound insulation, the vibration resistance, the stone chip resistance and so on, the PVC coating material is widely used in the gluing process for vehicles. The PVC coating material usually means the polyvinyl chloride paint, whose main ingredient is polyvinyl chloride resin, and the pigments, plasticizers, packings and so on can be added into the polyvinyl chloride resin to mix together so as to form a high solid content paint with a solid content of more than 90%. The PVC coating material can be divided into two types, i.e. the seam sealing glue and the underbody paint. The seam sealing glue has good flexibility, extensibility, rigidity and Resistance to abrasion and thus can take the effects of good airtightness, sound insulation and leakproof. The underbody paint is mainly sprayed at the bottom of the vehicle body and the four wheel housings, has higher rigidity, hardness and high adhesive force, and can take the effects of vibration resistance, stone chip resistance and protection for vehicle body. The seam sealing glue is mainly coated at the seam of the vehicle body through the glue gun. The underbody paint can be uniformly sprayed at the bottom of the vehicle body and the wheel housings mainly in the manner of spray coating.
- However, for the vehicle with a vehicle flange, when spray coating the underbody of the vehicle with the PVC coating material, due to the limitation of the machine and in order to prevent over-spray, it is impossible to completely coat the vehicle flange (especially the rocker panel under the vehicle door) with the glue, therefore the outside edge of the vehicle flange is not coated, that is, it has to keep a gap which is not coated. This gap is generally set in the range of 10mm to 15mm. However, if for example the accuracy of the machine is not sufficiently high and consequently the gap without being coated is too big, it will be necessary to separately and manually coat the outside edge of the vehicle flange. This would slow down the work cycle and would be quite uneconomical.
- The purpose of the present disclosure is to at least partly eliminate the above defects in the prior arts, in particular it can be not necessary any more to separately and manually coat the outside edge of the vehicle flange with glue when coating the underbody of the vehicle with glue.
- In view of this, the present disclosure provides a spray nozzle for coating a vehicle flange, especially for PVC coating, which comprises: two spray bodies, which are provided with a spray opening respectively; a connection bridge, which on both ends are each connected with a respective spray body; and a connection bar, which on one end is provided with a joint and on the other end is connected with the connection bridge, wherein, the two spray bodies, the connection bridge and the connection bar are connected with each other in the way of fluid-guiding, and wherein the connection bridge has an opening, which can receive the vehicle flange to be coated, and when the opening receives the vehicle flange to be coated, the spray openings of the two spray bodies can be oriented towards to the vehicle flange from the two opposite sides of the vehicle flange to be coated, respectively.
- Therefore, through the two spray bodies, the spray nozzle according to the present disclosure can make the coating material be coated on the vehicle flange simultaneously from two opposite sides of the vehicle flange to be coated (especially the top surface and bottom surface of the rocker panel). In this way, it is possible to simultaneously coat the two opposite sides of the vehicle flange to be coated in the seam sealing step, so that the bottom surface of the outside edge of the vehicle flange has been already coated in the seam sealing step. Therefore, it is not necessary any more to separately and manually coat the outside edge of the vehicle flange with glue in the underbody protecting step. Consequently, it is possible to avoid slowing down the work cycle and reducing the labor consumption.
- Preferably, the two spray bodies and the connection bridge are configured as cylindrical body, which can helpfully simplify the manufacture of the spray nozzle according to the present disclosure.
- Preferably, the spray openings are configured as strip-shape openings, hence the PVC coating material can be uniformly coated onto the two sides of the rocker panel in the form of a flat stream, and thus the coat has a uniform thickness. The flat stream is easy to control, so as to be able to better cover the coating area. Through adjusting the spraying angle of the spray opening, it is possible to coat the edge of the rocker panel entirely with the PVC coating material without insufficient spray or excessive spray. In addition, also preferably, when the opening receives the vehicle flange to be coated, the spray openings are symmetrically arranged with each other with respect to the vehicle flange to be coated. In this way, the PVC coating material can be identically coated on the two sides of the rocker panel.
- In this context, also preferably, when the opening receives the vehicle flange to be coated, the spraying direction of the spray opening is angled with respect to the vehicle flange to be coated in an angle which is not equal to 90 degrees. This also facilitates the coating material to be better covered on the coating area.
- Preferably, the connection bridge has a U-shape, especially a C-shape, a horseshoe-shape, or a hairpin turn-shape, whose two legs are each connected to a respective spray body. This facilitates the operation of the spray nozzle according to the present disclosure. In this context, also preferably, the longitudinal axis of the legs is angled with respective to the longitudinal axis of the respective spray body. This is also in favor of the operator to better operate the spray nozzle.
- Preferably, the connection bar has a folded part or a bending part. By means of the folded part or the bending part, it can ergonomically facilitate the operator to operate the spray nozzle more comfortably.
- Preferably, the connection bar is connected to the connection bridge in the middle of the connection bridge. Consequently, the operation of the spray nozzle by the operator can be better facilitated.
- In the present document, the vehicle flange can be the sill of the vehicle or the rocker panel of the vehicle.
- In addition, the present disclosure also provides a method for coating a vehicle with glue in the coating process, wherein the vehicle has a vehicle flange, especially the sill of the vehicle or the rocker panel of the vehicle, the method comprises the following steps: coating the vehicle body with the glue; coating the vehicle flange, especially the outside edge of the vehicle flange, by means of the above-described spray nozzle; and coating the underbody of the vehicle with the glue.
- Therefore, it is possible to simultaneously coat two opposite sides of the vehicle flange to be coated in the seam sealing step, so that the bottom surface of the outside edge of the vehicle flange has been already coated in the seam sealing step. Therefore, it is not necessary any more to separately and manually coat the outside edge of the vehicle flange with the glue in the underbody protecting step. Consequently, it is possible to avoid slowing down the work cycle and reducing the labor consumption.
- Preferably, the glue is coated on the vehicle body and/or the underbody of the vehicle by means of a robot, so as to achieve an automation process of the vehicle coating process to the great extent, so that it is possible to avoid slowing down the work cycle and reducing the labor consumption.
- Embodiments of the present disclosure will be explained in detail below with reference to the drawings, in which:
-
FIG. 1 shows a schematic front view of a vehicle with rocker panels in the vehicle coating process; -
FIG. 2 shows a perspective view of a spray nozzle according to the present disclosure; -
FIG. 3 shows a side view of the spray nozzle; -
FIG. 4 shows a section view ofFig. 3 in the plane of IV. -
Fig. 1 shows a schematic front view of a vehicle with rocker panels in the vehicle coating process. Thevehicle 1 at two sides has arocker panel 2 respectively. Therocker panel 2 belongs to a vehicle flange. In the present document, the term "vehicle flange" means a flange that protrudes from the vehicle body outwardly on the circumference of the vehicle body. - In order to spraying coat, the
rocker panel 2,Figs. 2-4 show a preferable embodiment of a spray nozzle for a spray gun according to the present disclosure. Firstly, as can be seen fromFig. 2 , the spray nozzle comprises: twospray bodies 100, aconnection bridge 200 for connecting the two spray bodies, and aconnection bar 300 for connecting the spray nozzle to the gun head (not shown) of the spray gun. For coating, the twospray bodies 100, theconnection bridge 200 and theconnection bar 300 can be connected with each other in the way of fluid-guiding. For example, the twospray bodies 100, theconnection bridge 200 and theconnection bar 300 can be configured as hollow or include a passage for guiding fluid respectively. - As seen from
Fig. 3 , thespray body 100 is preferably configured as cylindrical body. In this embodiment, thespray body 100 is configured as a circular cylinder, for example is made of a circular tube. Certainly, the spray body can be also configured as polygonal prismatic body. The twospray bodies 100 can be arranged parallelly with each other. Therefore, the twospray bodies 100 can be symmetrically arranged with each other with respect to the middle plane 101 between the twospray bodies 100, wherein the middle plane 101 indicates the normal plane of the planes in which the twospray bodies 100 are located and this normal plane passes through the center line of the twospray bodies 100. Therocker panel 2 to be coated can be positioned in the middle plane 101 between the twospray bodies 100. - The two
spray bodies 100 are provided with a spray opening respectively. When thevehicle 1 is coated, the spray openings of the twospray bodies 100 can coat therocker panel 2 simultaneously from the two opposite sides of therocker panel 2 to be coated. - The spray opening can be configured as strip-shape opening, hence the coating material, especially the PVC coating material, can be sprayed out in the form of a flat stream, which thus facilitates to uniformly coat with the coating material. During the coating of the
vehicle 1, the spray openings are preferably symmetrically arranged with each other with respect to therocker panel 2 to be coated, hence the coating material can be identically coated onto two sides of the rocker panel. When thespray body 100 is configured as cylindrical body, the spray opening can be configured as strip-shape opening extending along the axial direction of the respectivecylindrical spray body 100. Furthermore, the spray openings can be symmetrically arranged with each other with respect to the middle plane 101 between the twocylindrical spray bodies 100. In this context, preferably, the strip-shape openings can be centeredly arranged on the respectivecylindrical spray body 100. - As seen from
Fig. 3 , during the coating of thevehicle 1, the spraying direction of the spray opening is preferably angled with respect to the rocker panel to be coated in an angle which is not equal to 90 degrees. In other words, when thevehicle 1 is coated, the spraying direction of the spray opening is not vertical to the middle plane 101 between the twocylindrical spray bodies 100. - In addition, when the
spray body 100 is configured as cylindrical spray body, as seen fromFig. 4 , acap 100 can be arranged at both ends of eachcylindrical spray body 100 respectively, which facilitates to clean thecylindrical spray body 100. - The
connection bridge 200 has an opening, which can receive the rocker panel to be coated, and when the opening receives therocker panel 2 to be coated, the spray openings of the twospray bodies 100 can be oriented towards to therocker panel 2 from the two opposite sides (i.e. the top surface and the bottom surface) of therocker panel 2 to be coated, respectively. In this way, therocker panel 2 can be simply positioned into the opening of theconnection bridge 200, which facilitates the operator to better operate the spray nozzle according to the present disclosure. - In this embodiment, the
connection bridge 200 is also configured as cylindrical body. Theconnection bridge 200 can have a U-shape, but preferable have a C-shape, a horseshoe-shape, or a hairpin turn-shape. In this case, theconnection bridge 200 includes twolegs - A joint is provided in the middle of the connecting section of the
connection bridge 200, so as to connect with theconnection bar 300. For example, theconnection bridge 200 can be screwed or welded with theconnection bar 300. - The two
legs connection bridge 200 are each connected, preferably welded to arespective spray body 100. In this embodiment, the twolegs connection bridge 200 are each connected to acylindrical spray body 100, in particular at the middle part of the respectivecylindrical spray body 100, so that it is easy for the user to operate the spray nozzle. Preferably, as seen fromFig. 4 , thelongitudinal axis 202 of the twolegs connection bridge 200 is inclined with respect to thelongitudinal axis 102 of the twocylindrical spray bodies 100 in an angle a, so that when thecylindrical spray bodies 100 move along therocker panel 2, theconnection bridge 200 will not intervene with therocker panel 2. - The
connection bar 300 on one end is provided with a joint 310 and on the other end is connected with theconnection bridge 200. The joint 310 can be connected with the gun head (e.g. its hose) of the spray gun. The joint 310 can be a thread joint or a clamping joint. Theconnection bar 300 can be functioned as an operating handle. Theconnection bar 300 also can comprise a first section connecting with the joint 310 and a second section connecting with theconnection bridge 200. The first section and the second section can be angled with each other, preferably in an angle of about 120 degrees, which can ergonomically facilitate the operator to operate the spray nozzle more comfortably. - According to the prior arts, in the underbody protecting step, due to the limitation of the machine and in order to prevent over-spray, it is impossible to completely coat the vehicle flange (especially the rocker panel under the vehicle door) with the glue, therefore the outside edge of the vehicle flange is not coated, and thus it has to keep a gap which is not coated. Therefore, it might be necessary to separately and manually coat the outside edge of the vehicle flange in the underbody protecting step.
- Now, by means of the spray nozzle according to the present disclosure, since it includes two spray bodies and the spray openings of the spray bodies can coat the vehicle flange simultaneously from two sides of the vehicle flange, it is possible to coat two sides of the vehicle flange (i.e. the top and bottom surfaces of the rocker panel in this embodiment) with the PVC coating material. Therefore, the bottom surface of the vehicle flange can have been already coated with the PVC coating material at the meanwhile in the seam sealing step. Therefore, it is not necessary to coat the bottom surface of the vehicle flange during the coating of the underbody of the vehicle, and the phenomenon of insufficient spray or excessive spray would not appear. Therefore, it is possible to avoid slowing down the work cycle and reducing the labor consumption.
- Thus, the present disclosure also provides a method for coating a vehicle with glue in the coating process, wherein the vehicle has a vehicle flange, especially the sill of the vehicle or the rocker panel of the vehicle, the method comprises the following steps: coating the vehicle body with the glue; coating the vehicle flange, especially the outside edge of the vehicle flange, by means of the above-described spray nozzle; and coating the underbody of the vehicle with the glue. Therefore, it is possible to simultaneously coat two opposite sides of the vehicle flange to be coated in the seam sealing step, so that the bottom surface of the outside edge of the vehicle flange has been already coated in the seam sealing step. Therefore, it is not necessary any more to separately and manually coat the outside edge of the vehicle flange with the glue in the underbody protecting step. Consequently, it is possible to avoid slowing down the work cycle and reducing the labor consumption.
- According to the method of the present disclosure, the glue can be coated on the vehicle body and/or the underbody of the vehicle by means of a robot, so as to achieve an automation process of the vehicle coating process to the great extent, so that it is possible to avoid slowing down the work cycle and reducing the labor consumption.
- Where in the foregoing description reference has been made to integers or elements having known equivalents, then such equivalents are herein incorporated as if individually set forth.
