[0021] Please refer to Figure 1 and Figure 2 This utility model provides a multi-axis reciprocating spraying machine 100 for automotive parts, including: a spraying chamber 110, the spraying chamber 110 having a feeding port; A rotating mechanism 120 is provided at the feeding port. The rotating mechanism 120 includes at least one loading platform 121 and a rotating drive assembly connected to the loading platform 121. The spraying mechanism 130 is movably disposed within the spraying chamber 110 and is located above the rotating mechanism 120. The spraying mechanism 130 includes at least one spray gun 131 and a spraying drive assembly 132 connected to the spray gun 131.

[0022] The main function of the rotating mechanism 120 is to rotate the material from the feeding port 180° to the spraying station inside the spraying chamber 110, facilitating the spraying mechanism 130 to spray the material. The rotating mechanism 120 includes a material carrier platform 121, mainly used for feeding materials, which are transported onto the material carrier platform 121 by an upstream robotic arm or manually. The material of the material carrier platform 121 can be metal, such as stainless steel or aluminum alloy; it can also be engineering plastic, etc., depending on actual needs, and this utility model does not impose any limitations.

[0023] The loading platform 121 is connected to a rotary drive assembly, which can rotate from the loading port into the interior under the drive of the rotary drive assembly. The rotary drive assembly can be composed of a motor, reducer, transmission gears or chains, etc., to provide power and precise control for the rotation of the loading platform 121.

[0024] The main function of the spraying mechanism 130 is to spray PVC adhesive onto the material. It is positioned above the rotating mechanism 120 and can perform multi-axis motion within the spraying chamber 110, driving the spray gun 131 to achieve multi-directional and multi-trajectory motion. The spraying drive assembly 132 can be composed of servo motors, linear modules, etc.

[0025] In practical application, the operator or robot places the automotive parts to be painted on the loading platform 121 of the rotating mechanism 120. At this time, the loading platform 121 is located at the loading station of the loading port. The rotating drive component is started, driving the loading platform 121 to rotate 180°, transferring the parts from the loading station to the painting station in the painting chamber 110, ensuring that the parts are within the effective working range of the painting mechanism 130. The painting drive component 132 drives the spray gun 131 to perform multi-axis reciprocating motion above the parts according to the preset painting program. At the same time, the spray gun 131 atomizes the paint and sprays it evenly onto the surface of the parts to complete the painting of the designated area. After the painting is completed, the rotating mechanism 120 is started again, rotating the loading platform 121 from the painting station back to the loading station. At this time, the operator or equipment removes the painted parts and places new parts to be painted, entering the next work cycle.

[0026] This invention features a rotating mechanism 120 at the loading port of the spraying chamber 110. This mechanism includes a material carrier 121 that can support components. Driven by a rotating drive assembly, it rotates, concentrating material transport and spraying within the limited area of ​​the spraying chamber 110. The circular motion trajectory of the material carrier 121 replaces the linear transport path, significantly shortening the material movement distance and improving spraying efficiency. Simultaneously, it significantly reduces the footprint of the entire spraying machine, effectively solving the problem of low space utilization in traditional production lines and better adapting to the needs of compact workshop layouts. Furthermore, a spraying mechanism 130, including a spray gun 131 and a spraying drive assembly 132, is movably installed within the spraying chamber 110. The spray gun 131 can perform multi-axis motion above the components under the drive of the spraying drive assembly 132, flexibly adjusting its position according to the shape of the material and spraying requirements, enabling precise and comprehensive spraying, further improving spraying efficiency and effect.

[0027] Please refer to Figure 2 The rotary drive assembly includes a rotating component 1221 and a rotary connecting shaft 1222 connected to the rotating component 1221. The other end of the rotary connecting shaft 1222 is connected to the loading platform 121.

[0028] The rotating component 1221 can be a servo motor or a geared motor, etc., and its power is transmitted to the loading platform 121 through the rotating connecting shaft 1222, driving the loading platform 121 to rotate horizontally by 180°. The rotating connecting shaft 1222 can be made of a high-strength metal material, such as alloy steel, to avoid bending or deformation due to the load on the loading platform 121 or high-speed rotation, thus ensuring transmission stability.

[0029] The rotating mechanism 120 in this embodiment can be a single-station, dual-station, or multi-station mechanism. For example, the rotating mechanism 120 in this embodiment is a dual-station mechanism, with two sets of material carriers 121 arranged opposite to each other. One material carrier 121 holds the material to be sprayed, and when it rotates to the spraying station for spraying, the other material carrier 121 simultaneously feeds the material, thus achieving continuous production.

[0030] Please refer to Figure 1 , Figure 3 and Figure 4 The spraying drive assembly 132 includes two Y-axis guide rails 1321 disposed opposite to each other in the spraying chamber 110. The two Y-axis guide rails 1321 are connected to a Y-axis drive shaft 1322, and the Y-axis drive shaft 1322 is connected to a Y-axis motor. The two Y-axis guide rails 1321 are also slidably connected to a sliding frame 1323. The spray gun 131 is connected to the sliding frame 1323 to move relative to the feed port.

[0031] The Y-axis linkage shaft can be a lead screw, which converts the power of the Y-axis motor into linear motion, driving the sliding frame 1323 to slide linearly along the Y-axis guide rail 1321. The sliding frame 1323 spans between the two Y-axis guide rails 1321, and its bottom is slidably connected to the guide rails via a Y-axis slider. Its material can be aluminum alloy or welded steel plate, combining lightweight and structural rigidity to avoid deformation during high-speed movement.

[0032] After the parts are placed on the loading platform 121, the rotary drive assembly drives the parts to the spraying station in the spraying chamber 110. The sliding frame 1323 drives the spray gun 131 to move linearly along the Y-axis guide rail 1321 to the spraying position under the drive of the Y-axis motor and the Y-axis transmission shaft 1322. After the spraying is completed, it moves again along the Y-axis guide rail 1321 to the initial position near the loading port.

[0033] Please refer to Figure 3 and Figure 4 The spraying drive assembly 132 also includes an X-axis guide rail 1324 mounted on a sliding frame 1323. One end of the X-axis guide rail 1324 is connected to an X-axis motor, and a slider is also connected to the X-axis guide rail 1324. The other side of the slider is connected to the spray gun 131. By setting the X-axis guide rail 1324, the spray gun 131 can move linearly along the X-axis guide rail 1324, ensuring that the material is evenly sprayed along its entire length, thus improving the completeness of the spraying.

[0034] Please refer to Figure 3 and Figure 4 The spraying drive assembly 132 also includes a Z-axis guide rail 1325 connected to the slider. The spray gun 131 is located at the end of the Z-axis guide rail 1325, and a Z-axis motor is connected to the end of the Z-axis guide rail 1325 away from the spray gun 131. By setting the Z-axis guide rail 1325, the spray gun 131 moves up and down along the Z-axis guide rail 1325, and can adjust its distance from the material surface according to a preset program, thereby improving spraying accuracy and spraying effect.

[0035] Overspraying or dripping of paint is unavoidable during the spraying process. To effectively collect this residual paint, achieve resource recycling and reuse, and reduce environmental pollution, please refer to [the relevant documentation / reference]. Figure 5 The spraying machine of this utility model also includes a recycling mechanism 140, which is located inside the spraying chamber 110. The recycling mechanism 140 includes a scraping component and a recycling component located below the spraying mechanism 130.

[0036] The main function of the scraper assembly is to clean up waste materials. It can be a scraper blade 142 or a scraper plate, etc., and can be driven by a small cylinder or servo motor to make repeated linear movements to cover the entire recycling area. The recycling assembly can be set below the scraper assembly to collect the waste materials cleaned up by the scraper assembly.

[0037] In this embodiment, please refer to Figure 5 , Figure 6 and Figure 7 The coating assembly includes a conveyor belt 141 located below the spraying mechanism 130, with a coating scraper 142 at the bottom of the conveyor belt 141. During spraying, waste material drips onto the conveyor belt 141. As the conveyor belt 141 moves, the waste material adheres to it and moves to the bottom. At this point, the coating scraper 142, fixed at the bottom, touches the waste material and scrapes it off the conveyor belt 141. The scraped waste material then drips naturally into the recycling assembly under gravity and is collected. By setting a fixed coating scraper 142, it is ensured that the waste material is scraped off and collected at a fixed position, reducing the difficulty of recycling.

[0038] Please refer to Figure 5 The recycling assembly includes a container 143 located below the scraper blade 142, with wheels at its bottom. The container 143 features a top-opening box or barrel design, its dimensions matching the scraping area of ​​the scraper blade 142 to ensure waste falls completely into the container 143. It can be made of 304 or 316 stainless steel, offering excellent corrosion resistance and adaptable to the storage needs of various types of coatings.

[0039] The container 143 is equipped with four wheels at the bottom corners. When the waste in the container 143 reaches the preset capacity, the operator can push the container 143 and use the wheels to transfer the container 143 to the waste processing area or temporary storage area. Then, the empty container 143 is transferred to the area under the scraper assembly to ensure the continuity and efficiency of recycling.

[0040] In this embodiment, please refer to Figure 1 The site is equipped with a safety mechanism 150, which includes two guardrails 151 located on opposite sides of the feeding port. The two guardrails 151 are respectively equipped with sensors 152 and operation boxes 153.

[0041] Guardrails 151 are symmetrically arranged on opposite sides of the feed inlet, extending along the edge of the feed inlet to form a semi-enclosed protective area. The height is typically 800-1200mm, completely covering the hazardous area that personnel may come into contact with. Sensors 152, which can be light gratings, are installed inside the two guardrails 151 to detect whether personnel have entered the work area, triggering emergency shutdowns and alarms on the equipment to ensure the safety of on-site personnel.

[0042] The control box 153 includes an emergency stop button, a start button, or a reset button. When on-site personnel discover a malfunction in the sprayer, they can press the emergency stop button to stop the sprayer immediately. After maintenance, they can press the reset button to reset the sprayer and restart it, thus ensuring the stable operation of the sprayer.

[0043] The above are only some or preferred embodiments of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the contents of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
