Description

Technical Field

[0001] This utility model belongs to the field of door panel painting technology, and specifically relates to an auxiliary structure for electrostatic spraying of door panels. Background Technology

[0002] During the electrostatic spraying process of door panels, the entire door panel needs to be suspended in the air to spray paint one side of the panel. In existing spraying processes, connectors are usually welded to the edge of the door panel, and the door panel is suspended in the air using the connectors and a lifting device before electrostatic spraying.

[0003] However, this fixing method can easily affect the painting effect on the edges of the door panel. The fixing points directly block the parts of the door panel that are in contact with them, preventing the paint mist from reaching these areas. This results in these blocked areas having no paint layer or a very thin paint layer, creating obvious painting dead zones. At the boundaries of the fixing points, the distribution of paint mist is affected, causing abrupt changes in paint layer thickness. The transition from painted areas to the blocked, unpainted or thinly painted areas is unnatural, affecting the overall smoothness and appearance of the painted surface. After painting, the fixing device needs to be removed, and the edges of the door panel need to be touched up, affecting the painting efficiency and resulting in a high rework rate.

[0004] Therefore, this application provides an auxiliary structure for electrostatic spraying of door panels, which aims to eliminate fixed points on the edges of door panels, thereby avoiding their impact on the quality of door panel spraying. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0034] like Figure 1-2 As shown, an auxiliary structure for electrostatic spraying of door panels includes: a spray booth 1, a slide rail 102 is provided on the upper part of the spray booth 1, a sliding plate 6 is slidably provided on the slide rail 102, a connecting square tube 8 is provided on the lower part of the sliding plate 6, and a door panel 9 is connected to one side wall of the connecting square tube 8 through an adhesive layer.

[0035] The door panel is fixed by connecting square tubes and adhesive layers. This fixing method ensures that after one side of the door panel is painted, removing the connecting square tubes will not affect the edge of the already painted surface, thus ensuring the integrity of the painted edge, reducing rework rate, improving painting efficiency, and also preventing damage to the other side of the surface to be painted, thus affecting its painting effect.

[0036] One end of the spray booth 1 is a stationary area, and the other end is a spraying area. The upper part of the spraying area is connected to an upper suction pipe 2, and the lower part of the two side walls is connected to a side wall suction pipe 3. A paint mist collection plate 5 is provided at the lower part of the spraying area. The paint mist collection plate 5 is connected to the side wall suction pipe 3. The other end of the upper suction pipe 2 and the side wall suction pipe 3 are both connected to a collection chamber 4. A connection port 401 is provided on one side of the collection chamber 4. The connection port 401 is used to connect to an external negative pressure generating device.

[0037] The upper suction pipe 2 and the side wall suction pipe 3 transport the collected paint mist to the collection chamber 4 for centralized treatment. Connecting to an external negative pressure generator via the connection port 401 creates a stable airflow, ensuring the paint mist smoothly enters the collection chamber 4. Centralized paint mist treatment is not only environmentally friendly but also facilitates paint mist recycling, reducing production costs.

[0038] like Figure 6 As shown, the adhesive layer is a hot melt adhesive. A plurality of hot melt grooves 801 are provided on the side of the connecting square tube 8 that mates with the door panel 9. The plurality of hot melt grooves 801 are arranged parallel to each other at equal intervals and along the length direction of the connecting square tube 8. A heating component 802 is provided in the inner cavity of the connecting square tube 8. The heating component 802 is used to heat the side of the connecting square tube 8 that mates with the door panel 9.

[0039] The hot melt grooves 801, which are equidistant and parallel and arranged along the length direction on the side where the connecting square tube 8 and the door panel 9 meet, facilitate the placement of hot melt glue sticks and increase the contact area between the hot melt glue and the connecting square tube 8, thereby enhancing the mechanical interlocking force between the door panel 9 and the connecting square tube 8 and making the connection between the two more stable.

[0040] The heating component 802, located inside the connecting square tube 8, heats the side of the connecting square tube 8 that mates with the door panel 9. Because hot melt adhesive melts at a specific temperature, the heating component 802 precisely transfers heat to the area where the hot melt adhesive is located when the door panel needs to be removed. This precise heating method avoids unnecessary heat impact on other parts of the door panel, reducing the risk of deformation or damage due to heating. Once the hot melt adhesive melts, the bond between the door panel 9 and the connecting square tube 8 quickly disappears, allowing the operator to easily separate the door panel 9 from the connecting square tube 8. Compared to traditional bonding methods, this disassembly method, which uses heating to melt the hot melt adhesive, is more convenient and efficient, significantly shortening disassembly time and improving work efficiency.

[0041] like Figure 6 As shown, a pair of pull rings 10 are provided on the side of the connecting square tube 8 away from the door panel 9.

[0042] like Figure 3-4 As shown, the two side walls of the sliding plate 6 are respectively provided with two sets of longitudinal pulleys 601 and two sets of transverse pulleys 602, and the two sets of longitudinal pulleys 601 and transverse pulleys 602 are symmetrically distributed on the sliding plate 6. The longitudinal pulleys 601 are used to cooperate with the bottom surface of the groove in the slide rail 102, and the transverse pulleys 602 are used to cooperate with the side wall of the groove in the slide rail 102.

[0043] The longitudinal pulley 601 engages with the bottom surface of the groove in the slide rail 102, and the transverse pulley 602 engages with the side wall of the groove, transforming the sliding friction between the sliding plate 6 and the slide rail 102 into rolling friction. The frictional force of rolling friction is much less than that of sliding friction, making it easier for the sliding plate 6 to move on the slide rail 102 with less driving force. During the painting process, whether moving the door panel from the stationary area to the painting area or moving it back after painting, the operation is smoother, improving work efficiency.

[0044] like Figure 4 As shown, the lower part of the sliding plate 6 is connected to a pair of hanging ears 603 via an extension rod. A traction rope 7 is connected to each of the two hanging ears 603. The other end of the traction rope 7 is connected to the end of the connecting square tube 8.

[0045] like Figure 4 As shown, both ends of the traction rope 7 are provided with buckles 701, and both ends of the connecting square tube 8 are provided with connecting holes for cooperating with the buckles 701.

[0046] like Figure 2 and Figure 5As shown, a grid plate 501 is provided on the upper surface of the paint mist collection plate 5, and a receiving cavity 502 is provided at the lower part of the grid plate 501. The receiving cavity 502 is connected to the side wall suction pipe 3. The grid plate 501 can play a certain filtering role, intercepting larger paint mist particles and impurities, preventing them from directly entering the receiving cavity 502 and the side wall suction pipe 3 and causing blockage. This reduces the frequency of cleaning and maintenance required due to blockage, and lowers maintenance costs and downtime.

[0047] like Figure 1 As shown, an entrance 101 is provided in the middle of one side wall of the spray booth 1.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
