Description

Technical Field

[0001] This utility model relates to the field of UV spraying turntable technology, specifically a UV spraying turntable with spray liquid recovery function. Background Technology

[0002] UV curing technology, with its advantages of fast curing speed, high production efficiency, and relatively low VOC emissions, has been widely used in mass production fields such as automotive parts and electronic components. In large-scale production, rotary coating equipment has become a key piece of equipment for increasing production capacity because it can achieve continuous workpiece conveying and multi-sided coating.

[0003] Chinese patent CN205340449U discloses a dry UV paint mist recovery and purification system, including a paint recovery platform, a paint condenser, and at least one paint separator. The paint recovery platform is located below the spraying device, and all paint separators are sequentially arranged on the paint recovery platform, with the paint condenser located after the last paint separator. Paint mist scattered in the air is guided by the exhaust airflow, separated by each paint separator in sequence, and filtered by the paint condenser before being condensed and collected along with oversprayed paint by the paint recovery platform. This patent recovers and purifies oversprayed paint and paint mist through paint separators and paint condensers, respectively, thereby collecting the paint mist.

[0004] The existing technology uses a paint separator and a paint coagulant to recover and purify oversprayed paint and paint mist, respectively, thereby collecting the paint mist. However, the paint on the product will flow down from the turntable, causing a lot of paint to fall to the bottom of the spray booth, making paint recovery difficult. Utility Model Content

[0005] The purpose of this invention is to provide a UV spraying turntable with a spraying liquid recovery function. By setting a disc with a diameter greater than the distance between two symmetrical receiving discs, it can catch dripping paint. The paint flows into the recovery component and is returned to the spraying robot for spraying, solving the problem of paint flowing into the bottom of the spraying chamber and causing recycling difficulties.

[0006] To address the problems of existing technologies, this utility model provides a UV spraying turntable with a spraying liquid recovery function, comprising: a spraying chamber body, the spraying chamber body having a partition baffle that divides the interior of the spraying chamber body into a spraying cavity and a loading cavity; a turntable assembly, disposed at the bottom of the interior of the spraying chamber body, transferring the product from the loading cavity to the spraying cavity; a recovery assembly 3, disposed in the spraying cavity for recovering the coating liquid; a spraying robot, disposed in the spraying cavity and connected to the recovery assembly 3, spraying the coating liquid in the recovery assembly 3 onto the product; and a fixture lifting assembly, disposed in the loading cavity inside the spraying chamber body for facilitating product loading; the turntable assembly includes a driver installed at the bottom of the interior of the spraying chamber body and a disc 21 mounted on the top shell of the driver, and the disc has a through hole for the coating liquid to flow into the recovery assembly; the turntable assembly also includes a station conversion assembly rotatably disposed directly above the disc for transferring the product from the loading cavity to the spraying cavity.

[0007] Preferably, the workstation conversion component includes a rotatable connecting plate positioned directly above the disc, the output end of the driver being connected to the connecting plate, a plurality of support frames being evenly arranged on the outer side of the connecting plate, and a support plate being connected to the end of the support plate away from the connecting plate.

[0008] Preferably, the workstation conversion assembly includes a receiving plate that can be detachably mounted on a support plate, the edge of the receiving plate extending upward, and the top of the receiving plate also having a detachable support fixture for placing the product.

[0009] Preferably, the support plate, the receiving plate, and the support fixture all have through holes at their center positions.

[0010] Preferably, the disc is provided with a through hole concentric with the support disc and the receiving disc at the loading station of the station conversion component, and the diameter of the disc is larger than the distance between the two symmetrical receiving discs.

[0011] Preferably, the recycling assembly includes a recycling chamber inclinedly disposed at the lower part of the spraying chamber, a temporary storage chamber is provided at the bottom of the recycling chamber, and a filter screen for filtration is provided at the top inside the recycling chamber.

[0012] Preferably, the recycling component further includes a return pipe connected to the temporary storage chamber, one end of which is connected to the spraying pump of the spraying robot.

[0013] The advantages of this utility model compared to the prior art are:

[0014] This application features a disc fixedly mounted on the top housing of the driver. The driver's output end connects to a connecting disc, and several support frames are evenly distributed and connected to the connecting disc, with each support frame connected to a support disc at its end. In terms of size design, the diameter of the disc is larger than the distance between two symmetrical support discs. Simultaneously, through holes are formed at the center of the support disc, receiving disc, and support fixture, creating a flow channel for the paint. During the spraying process, excess paint on the product surface drips into the receiving disc and then flows into the disc through the through holes on the receiving disc and support disc. The paint flowing into the disc further flows into a recycling component, thus achieving paint recycling and solving the problem of traditional paint falling to the bottom of the spray booth body, causing recycling difficulties. To ensure the purity of the recycled paint, a filter screen is installed inside the recycling chamber of the recycling component. This filter screen effectively filters impurities in the paint, improving the quality of the recycled paint for subsequent reuse. Attached Figure Description

[0019] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0020] Reference Figures 1-3As shown, this utility model provides a UV spraying turntable with a spraying liquid recovery function, including: a spraying chamber body 1, which has a partition baffle 11 inside to divide the interior of the spraying chamber body 1 into a spraying chamber and a loading chamber; a turntable assembly 2, which is set at the bottom inside the spraying chamber body 1 and transfers the product from the loading chamber to the spraying chamber; a recovery assembly 3, which is set in the spraying chamber for recovering the coating liquid; a spraying robot 4, which is set in the spraying chamber and connected to the recovery assembly 3 so that the coating liquid in the recovery assembly 3 is sprayed onto the product; and a fixture lifting assembly 5, which is set in the loading chamber inside the spraying chamber body 1 for facilitating product loading; the turntable assembly 2 includes a driver 22 installed at the bottom inside the spraying chamber body 1 and a disc 21 installed on the top shell of the driver 22. The driver 22 provides power (such as a motor, gearbox, etc.) to the turntable assembly 2, driving the entire assembly to rotate at a set speed to ensure the continuity of product transfer. Furthermore, the disc 21 has through holes for the paint to flow into the recycling component 3; the turntable assembly 2 also includes a station conversion component rotatably positioned directly above the disc 21 for transferring the product from the feeding chamber to the spraying chamber. The disc 21 serves to collect excess paint dripping during the spraying process and guides the paint into the recycling component 3 below through the through holes, providing a channel for paint recycling. The station conversion component includes a rotatable connecting disc 26 positioned directly above the disc 21. The output end of the driver 22 is connected to the connecting disc 26. Several support frames 23 are evenly arranged on the outer side of the connecting disc 26, and a support disc 231 is connected to the end of the support disc 231 away from the connecting disc 26.

[0021] The workstation conversion assembly includes a receiving plate 24 that can be detachably mounted on a support plate 231, the edge of the receiving plate 24 extending upward, and a support fixture 25 for placing products can also be detachably mounted on the top of the receiving plate 24.

[0022] Workers use a picking robot to pick up products. The jig lifting component 5 raises the supporting jig 25, which then contacts the product. The picking robot places the product onto the supporting jig 25, and the jig lifting component 5 lowers, placing the supporting jig 25 onto the supporting plate 231. The drive 22 of the turntable component 2 is activated, causing the station conversion component (carrying the product) to rotate above the disc 21, transferring the product to be sprayed from the loading chamber to the spraying chamber. Once the product enters the spraying chamber, the spraying robot 4 starts, using its own nozzle (with paint sources including new paint and recycled paint supplied by the recycling component 3) to spray the product. Excess paint during spraying (such as dripping paint) falls onto the disc 21 and flows through the disc's holes into the recycling component 3 below, completing paint recycling. The recycling component 3 then transports the recycled paint (after processing) back to the spraying robot 4 for reuse in spraying subsequent products, achieving paint recycling. After the coating is completed, the station conversion component continues to rotate, transferring the coated product out of the coating chamber (to the unloading position), while a new product to be coated is transferred from the upper chamber into the coating chamber, forming a continuous production cycle.

[0023] The support plate 231, the receiving plate 24, and the support fixture 25 all have through holes at their center positions. The disc 21 also has through holes concentric with the support plate 231 and the receiving plate 24 at the loading station of the station conversion assembly. The diameter of the disc 21 is larger than the distance between the two symmetrical receiving plates 24.

[0024] The diameter of disc 21 is designed to be larger than the distance between the two symmetrical receiving discs 24, meaning that disc 21 can completely cover the area below all receiving discs 24. Its function is to ensure that no matter which position the station conversion component is rotated to (spraying chamber, feeding chamber, or transition position), the paint dripping from the receiving discs 24 can be caught by disc 21, preventing paint from dripping directly to the bottom of the equipment and causing waste or pollution, and ensuring that the recycling component 3 can efficiently collect all excess paint.

[0025] The recycling assembly 3 includes a recycling chamber 31 inclinedly disposed at the lower part of the spraying chamber, a temporary storage chamber 33 disposed at the bottom of the recycling chamber 31, and a filter screen 32 disposed at the top inside the recycling chamber 31 for filtration. The recycling assembly 3 also includes a return pipe 34 connected to the temporary storage chamber 33, one end of the return pipe 34 being connected to the spraying pump of the spraying robot 4.

[0026] During the spraying process, excess paint drips through the through-holes of the turntable assembly 2 (disc 21, support disc 231, receiving disc 24, etc.) and enters the lower part of the spraying chamber. The dripping paint is received by the recovery chamber 31 (tilted design) and automatically collected to the filter 32 at the top. After being filtered by the filter 32 to remove impurities, the paint flows into the temporary storage chamber 33 at the bottom for temporary storage. The clean paint in the temporary storage chamber 33 is transported to the spraying pump of the spraying robot 4 through the return pipe 34 and reused as a spraying material.

[0027] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
