Description

Technical Field

[0001] The invention relates to the technical field of automobile component processing equipment, and in particular to an automobile component glue spraying system. Background Art

[0002] Auto parts (such as central armrests, door armrests, etc.) need to be applied to the glue spraying process during the processing. In the prior art, glue spraying can be performed by hand-held spray guns, but this often leads to low work efficiency and is not friendly to the health of operators. Therefore, the prior art has gradually changed to automatic glue spraying. For example, a nozzle can be set in a box, the workpiece to be sprayed with glue is placed in the box, the glue is pumped into the box through a pump body and then sprayed out through the nozzle. At the same time, the box can also be connected to an exhaust fan to generate negative pressure in the box, and the glue will not overflow, thereby avoiding threats to the health of the operator. At the same time, the nozzle can be set to multiple, and the workpiece can be sprayed from different angles to achieve a wider coverage range; a manipulator can also be used to assist the nozzle to spray the workpiece at multiple angles, which can further improve the work efficiency. However, in the actual processing process, due to the operation of the exhaust fan, a pulling action in one direction will be generated in the box, so that the sprayed glue also has a tendency to move in one direction, resulting in a large amount of glue being directly drawn away, and the glue is seriously wasted. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides an automobile parts glue spraying system, which solves the problem in the prior art that a large amount of glue may be directly sucked away due to the operation of the exhaust fan, resulting in serious waste of glue.

[0005] In the above embodiment, a curtain structure is provided in the box body to block the front of the orifice plate. The mesh curtain of the curtain structure can disperse the pumping action of the exhaust fan to a wider range, thereby preventing the glue liquid from moving in a single direction and causing a large amount of glue liquid to be extracted. Therefore, the problem in the prior art that a large amount of glue liquid may be directly extracted due to the operation of the exhaust fan, resulting in serious waste of glue liquid, is solved.

[0006] Furthermore, the support frame includes a pair of vertical rods respectively detachably connected to the top surface of the box body, and a steel mesh fixed between the two vertical rods. The mesh curtain covers the steel mesh and is pressed by a magnetic strip.

[0008] Furthermore, a threaded sleeve is fixedly connected to the inner top surface of the box body, a threaded column is rotatably connected to the upper end of the vertical rod, and the threaded column is threadedly connected to the threaded sleeve.

[0009] Furthermore, the lower end of the vertical rod is telescopically connected with an insertion rod, and the insertion rod is not detached from the vertical rod. A pair of insertion holes for the two insertion rods to be inserted respectively are provided on the supporting plate.

[0010] Furthermore, two sides of the support plate extend obliquely upward respectively, and two insertion holes are respectively arranged on the inclined surfaces on the two sides.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By setting a curtain structure in the box, the suction effect of the exhaust fan is dispersed to a wider range by the net curtain, so as to prevent the glue liquid from moving in a single direction and being sucked out in large quantities, thus solving the problem in the prior art that a large amount of glue liquid may be directly sucked out due to the operation of the exhaust fan, resulting in serious waste of glue liquid;

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] In an exemplary embodiment, Figure 1-6As shown, this embodiment provides an automobile parts glue spraying system, which includes a box body 1, one side of the box body 1 is provided with an opening, a support plate 2 is fixedly connected to the box body 1, the support plate 2 is used to place the workpiece in the box body 1, and a nozzle 3 similar to that in the prior art is also provided in the box body 1 for implementing the glue spraying operation. Furthermore, a liquid receiving tank 4 is provided below the support plate 2, and a connecting channel connecting the upper part thereof with the liquid receiving tank 4 is provided on the support plate 2; an exhaust box 5 is provided on the side of the box body 1 away from the opening, and the exhaust box 5 is connected to the box body. 1 is provided with a perforated plate 6, and a plurality of connecting holes 7 are provided on the perforated plate 6, and the exhaust box 5 is also connected to the exhaust fan; a curtain structure is also provided in the box body 1 between the perforated plate 6 and the opening, and the curtain structure includes a support frame relatively fixed to the box body 1 and a net curtain 8 covering the support frame, and the net curtain 8 fully covers the perforated plate 6. In detail, the structures such as the perforated plate 6 and the exhaust box 5 are similar to those in the prior art, and the perforated plate 6 is provided with holes, which can allow airflow to pass through when the exhaust fan is running, thereby forming a negative pressure in the box body 1.

[0029] In the above embodiment, a curtain structure is provided in the box body 1 to block the front of the orifice plate 6. The net curtain 8 of the curtain structure can disperse the pumping action of the exhaust fan to a wider range, thereby preventing the glue liquid from moving in a single direction and being extracted in large quantities. Therefore, the problem in the prior art that a large amount of glue liquid may be directly extracted due to the operation of the exhaust fan, resulting in serious waste of glue liquid, is solved. Furthermore, in the present solution, a reflux port 9 is provided between the exhaust box 5 and the box body 1 and is located below the orifice plate 6 and is connected to each other. Part of the glue liquid entering the exhaust box 5 can also flow back to the box body. 1, and then go to the liquid receiving tank 4 through the connecting channel. There will be excess glue in the box body 1, which also goes to the liquid receiving tank 4 through the connecting channel, and can be recycled again to avoid waste of glue. In more detail, a support plate 10 for supporting the support plate 2 is fixedly connected in the liquid receiving tank 4 to improve the stability of the support plate 2. A notch 11 is also provided at the lower end of the support plate 10 to ensure that the liquid receiving tank 4 is connected. A drain pipe 12 connected to the liquid receiving tank 4 is also fixedly connected to the bottom of the box body 1, and the drain pipe 12 is used to guide the glue in the liquid receiving tank 4.

[0030] like Figure 1-5As shown, in a more detailed implementation scheme, the support frame provides a supporting foundation for the mesh curtain 8 to cover. Specifically, the support frame includes a pair of vertical rods 13 detachably connected to the top surface of the box body 1, and a steel mesh 14 fixed between the two vertical rods 13. The mesh curtain 8 covers the steel mesh 14 and is pressed by a plurality of magnetic strips 15. The magnetic strips 15 are magnetically adsorbed with the steel mesh 14 to press the mesh curtain 8 onto the steel mesh 14. At the same time, the lower end of the magnetic strip 15 extends to the bottom of the steel mesh 14, and part of the glue can be guided downward along the magnetic strip 15, thereby falling onto the support plate 2. Among them, the mesh holes on the steel mesh 14 are relatively large, which mainly play a supporting role, while the mesh curtain 8 is fine and small holes, so that when the exhaust fan is running, During operation, negative pressure is first generated in the exhaust box 5, and then negative pressure is generated in the box body 1 through the connecting holes 7 on the orifice plate 6, and the mesh curtain 8 blocks the front of the orifice plate 6, so that the airflow needs to pass through more and wider small holes to pass through the mesh curtain 8, so that the glue liquid (in atomized state) flowing with the airflow can be attached to the mesh curtain 8 in a spreading manner, and avoids directly entering the connecting holes 7 on the orifice plate 6 in strands. After attaching to the mesh curtain 8, the glue liquid will flow downward as the amount increases, and the magnetic strips 15 provided can allow the surrounding glue liquid to attach and guide it downward, so that the glue liquid can flow downward in strands, so as to maintain only a small amount of glue liquid on the mesh curtain 8, and avoid a large amount of glue liquid covering the airflow so that the airflow cannot pass normally.

[0031] like Figure 1-6 As shown, in further detail, a threaded sleeve 16 is fixedly connected to the inner top surface of the box body 1, and a threaded column 17 is rotatably connected to the upper end of the vertical rod 13. The threaded column 17 is threadedly connected to the threaded sleeve 16, so that the support frame can be disassembled, which is convenient for subsequent cleaning and maintenance. The set steel mesh 14 has a certain flexibility and can be rolled up with one of the vertical rods 13 as the axis, or it can be unfolded, which is convenient for subsequent storage; the net curtain 8 can be made of yarn woven material, which can be removed for cleaning and can also be directly replaced, which is low in cost. During specific operation, the glue may form a film on the small holes on the mesh curtain 8, but due to the effect of negative pressure, the center of the film after formation will be ruptured by the pressure difference (i.e., the center position of the small hole) to allow air flow to pass through, while the glue adheres to the surrounding of the small hole, may form a film again, and then rupture again. Therefore, in the alternating process of repeated film formation and rupture, the accumulated glue flows downward. In order to better guide the glue, the magnetic strip 15 can be tilted, so that the glue is more likely to contact the magnetic strip 15 during the downstream process, thereby converging into a stream and flowing obliquely downward.

[0032] In further detail, Figure 1 , 4As shown, the upper end surface of the vertical rod 13 is recessed to form a first mounting cavity 18 with an inverted T-shaped cross-section, and the lower end of the threaded column 17 is an inverted T-shaped first mounting head 19 with a smooth outer wall. The first mounting head 19 is rotatably mounted in the first mounting cavity 18, thereby realizing rotational installation, and at the same time, the vertical rod 13 is not disengaged from the threaded column 17. Finally, the vertical rod 13 is suspended by the threaded sleeve 16 and the threaded column 17 to be stable.

[0033] In a further solution, Figure 1 , 5 As shown, the lower end of the vertical rod 13 is also telescopically connected to the plug rod 20, and the plug rod 20 is not detached from the vertical rod 13. A pair of insertion holes 21 for inserting the two plug rods 20 are also provided on the support plate 2. A T-shaped second mounting head 22 is provided at the upper end of the plug rod 20, and the plug rod 20 includes a T-shaped sliding section 23 located at the upper end and a straight rod section 24 located at the lower end. The straight rod section 24 passes through the provided insertion hole 21. A second mounting cavity 25 is recessed on the lower end surface of the vertical rod 13. A support ring 26 is fixedly connected in the second mounting cavity 25. The upper end of the second mounting head 22 is located above the support ring 26, and a limit ring is provided at the end. 27, when the limit ring 27 is at the lowest position, it abuts against the supporting ring 26, and the straight rod section 24 is inserted into the insertion hole 21. When the limit ring 27 is at the highest position, the straight rod section 24 is located above the insertion hole 21. After the inserted rod 20 is inserted into the insertion hole 21, a limit is provided at the lower end of the vertical rod 13, so that the lower end of the vertical rod 13 is also supported, thereby being more stable, and the steel mesh 14 and the mesh curtain 8 are also correspondingly more stable; furthermore, the inserted rod 20 arranged in this way can also receive the glue from the vertical rod 13, so that the glue can be more smoothly guided to the insertion hole 21 and then fall into the liquid receiving tank 4.

[0034] like Figure 1 , 5 As shown, in more detail, the two sides of the support plate 2 extend obliquely upward and the two jacks 21 are respectively arranged on the inclined surfaces 28 on both sides. The inclined surfaces 28 allow the glue thereon to gather toward the middle and then pass through the arranged connecting channel to the liquid receiving tank 4; in further detail, the connecting channel includes a pair of channels arranged on the lower side of the two inclined surfaces 28, a support ring 29 is fixedly connected in the connecting channel, and a filter plate 30 is also overlapped on the support ring 29 to filter the fallen glue and prevent impurities from falling into the liquid receiving tank 4 below. At the same time, the filter plate 30 can also be disassembled for cleaning.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
