Description

Technical Field

[0001] This utility model relates to a gantry-type hot melt adhesive spraying device, belonging to the technical field of automated spraying. Background Technology

[0002] Hot melt adhesive spraying is a process technology that involves heating hot melt adhesive materials to a molten state using specialized equipment and then spraying them onto the surface of a substrate in a specific manner. It is widely used in packaging, hygiene products, automobile manufacturing, and many other fields. Its core principle is to use equipment to transform solid hot melt adhesive into a fluid state, and then achieve precise coating through components such as spray guns. It has advantages such as high efficiency, environmental friendliness, and high adhesive strength.

[0003] There is currently a demand for painting automotive structural components, including various sheet metal parts such as storage support panels and spare tire panels. These components require hot melt adhesive spraying while supported on a support platform to meet the needs of subsequent adhesive assembly. Existing technologies employ two methods: the first is fixed-distance spraying, which uses a matrix-distributed spraying device for fixed-distance spraying; the second is robotic arm spraying, which uses the track displacement of a robotic arm to achieve surface spraying. Due to the use of a support platform, the spraying efficiency is relatively low; fixed-distance spraying results in unnecessary adhesive waste; and robotic arm spraying is more expensive. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the prior art and to propose a gantry-type hot melt adhesive spraying device, which addresses the problems of material waste in fixed-distance spraying and high cost of robotic arms in traditional spraying.

[0012] Preferably, the gantry-type hot melt adhesive spraying device includes two sets of adhesive supply equipment, and each of the adhesive supply equipment is provided with an adhesive supply mating end for supplying adhesive to the spraying frame.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0024] This utility model provides a gantry-type hot melt adhesive spraying device, such as Figures 1 to 5 As shown, the gantry body 1 includes two spaced-apart lifting frame mechanisms 2 and a horizontal beam mechanism 3 bridging the two lifting frame mechanisms 2.

[0025] The arbitrary lifting frame mechanism 2 includes a pallet frame 20 with lifting displacement for supporting the material pallet 100, and the pallet frames 20 of the two lifting frame mechanisms are arranged opposite to each other.

[0026] The horizontal beam mechanism 3 includes a horizontal beam rail 31 and a spray frame 32 with linear displacement mounted on the horizontal beam rail. The spray frame 32 is provided with a plurality of spray ends 320 linearly spaced, and the linear direction of the plurality of spray ends is perpendicular to the linear direction of the spray frame.

[0027] Detailed implementation process and principle explanation: When performing adhesive spraying operations, such as Figure 1As shown, after the plate structure is mounted on the pallet frame 20, it rises to a suitable position with the spray end 320.

[0028] At this time, the spraying frame 32 performs linear displacement spraying operation. Through the linear arrangement of several spray ends 320, surface spraying is achieved, so the spraying range is controllable and the spraying quality is significantly improved.

[0029] It should be noted that the two lifting frame mechanisms 2 share the same spraying frame 32, which meets the requirements of tidal switching operations and ensures efficient and smooth operation.

[0030] In one specific embodiment, the pallet frame 20 includes a frame base plate 21 and a barrier 22 with an opening end 220 disposed on the frame base plate 21, wherein the opening ends 220 of the two frame base plates are located on the same side.

[0031] The arrangement of the opening ends 220 on the same side facilitates loading and unloading operations on the same side, while the enclosure 22 meets the requirements for limiting and protecting the outer perimeter.

[0032] In one specific embodiment, the frame base plate 21 is provided with an extended inclined plate 210 that cooperates with the opening end, and the enclosure is provided with a wide guide end that cooperates with the opening end.

[0033] This convenient material feeding guide effectively prevents hard collisions, while the extended inclined plate 210 is used for overflow, preventing adhesive from accumulating on the plate and reducing cleaning difficulty.

[0034] In one specific embodiment, the lifting frame mechanism 2 includes a column body 23, a lifting platform 24 slidably connected to the column body, and a lifting drive source 25 that is connected to the lifting platform in a transmission manner.

[0035] The lifting platform and the pallet frame are detachably connected.

[0036] The lifting drive source 25 can drive the lifting platform 24 to move up and down.

[0037] It should be noted that the spray painting rack 32 can be equipped with a distance sensor facing the base plate 21 of the frame. Any sensor that can measure distance is within the protection scope of this case. The distance sensor is connected to the lifting drive source 25 to realize automated height adjustment.

[0038] In one specific embodiment, the lifting drive source 25 includes a rotary power unit 251 and a transmission screw 252 that is driven by the lifting platform. The rotary power unit is driven by the transmission screw.

[0039] The rotating power unit 251 is generally a servo motor, which meets the rotation drive requirements of the transmission screw 252, thereby achieving relatively reliable and accurate lifting displacement drive control.

[0040] In one specific embodiment, a linear rack 311 is provided on the horizontal beam rail 31, the spraying frame 32 is slidably disposed on the horizontal beam rail, and a rotary drive source 321 is provided on the spraying frame, the rotating end of the rotary drive source is provided with a meshing transmission gear plate that meshes with the linear rack.

[0041] This satisfies the requirements of meshing transmission and enables linear displacement drive.

[0042] In one specific embodiment, at least one distance sensor is provided on the horizontal beam rail 31 facing the pallet frame, and the distance sensor is communicatively connected to the lifting frame mechanism.

[0043] This satisfies the requirements for mounting a ranging sensor, thereby enabling automated height adjustment.

[0044] In one specific embodiment, the gantry-type hot melt adhesive spraying device includes two sets of adhesive supply devices 4, each of which is provided with an adhesive supply mating end for mating with the spraying frame.

[0045] It meets the layout requirements of one unit per use, and the layout is compact and easy to construct.

[0046] As described above, this invention replaces the traditional multi-axis robotic arm for spraying by using a horizontal beam mechanism and a lifting frame mechanism, meeting the needs of dual-station sharing and automated relative displacement adjustment, thus significantly reducing equipment costs. It meets the requirements for automated spraying stroke adjustment and employs tidal operation, significantly improving spraying efficiency. Spraying uniformity and coverage are guaranteed, significantly improving product qualification rate while reducing adhesive waste. The overall layout is compact, with high space utilization.

[0048] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
