Description

Technical Field

[0001] This application relates to the field of workpiece painting, and more particularly to a workpiece conveying device for a spray booth. Background Technology

[0002] A spray booth is a specialized enclosed space used for painting workpieces. It is commonly used in industrial manufacturing, automobile repair, woodworking and other fields.

[0003] Currently, in the actual production of the factory, the applicant needs to paint plate-shaped workpieces, such as laptop shells. During the painting process, the workers first neatly place the plate-shaped workpieces to be painted on the conveyor belt, and then the conveyor belt sequentially transports the plate-shaped workpieces to the spray booth. Finally, the spray guns in the spray booth reciprocate to paint the surface of the workpieces.

[0004] However, in actual production processes, current conveyor belts exhibit swaying in all directions during workpiece transport. This swaying causes disordered flow of paint on the workpiece surface, ultimately resulting in uneven paint coverage on plate-shaped workpieces. Therefore, how to achieve more stable transport of plate-shaped workpieces and improve paint uniformity has become a pressing technical challenge. Utility Model Content

[0005] To address the issue of stability in conveying plate-shaped workpieces, this application provides a spray booth workpiece conveying device.

[0006] First, the spray booth workpiece conveying device provided in this application adopts the following technical solution: A spray booth workpiece conveying device includes a production line frame for mounting the spray booth workpiece conveying device. The spray booth workpiece conveying device further includes a conveyor chain, a conveyor chain support groove, and a conveyor bracket. The conveyor chain is arranged horizontally along a straight direction, and two conveyor chains are arranged symmetrically side by side. The conveyor chain support groove is horizontally installed on the frame and supports the conveyor chain below along the extension direction of the conveyor chain. The groove opening of the conveyor chain support groove faces upward and supports the conveyor chain below and on both sides. The conveyor bracket is horizontally arranged and located between the two conveyor chains. The two sides of the conveyor bracket are correspondingly connected to the conveyor chains. The frame is provided with a motor and a sprocket for driving the conveyor chains.

[0007] Preferably, there are multiple conveying supports, which are installed sequentially on the conveyor chain along the direction of the frame; each conveying support includes a rectangular support frame and several pillars vertically fixed to the support frame.

[0008] Preferably, the support frame includes four longitudinal support rods parallel to the conveyor chain and two transverse support rods perpendicular to the longitudinal support rods, with the two transverse support rods fixedly connected to both ends of the four longitudinal support rods respectively; a number of pillars are installed at intervals on the longitudinal and transverse support rods, with the upper ends of the pillars at the same horizontal height.

[0009] Preferably, the spray booth workpiece conveying device further includes an auxiliary guide rail parallel to the conveyor chain and supported below the conveyor bracket. The auxiliary guide rail is horizontally installed on the frame and fits against the side of the conveyor chain support groove.

[0010] Preferably, the auxiliary guide rail includes a base plate and an overlap. The base plate is fixed on the frame and its surface is in contact with the side of the conveyor support groove. The overlap is integrally formed on the upper edge of the base plate and is horizontally arranged and supported below the conveyor bracket.

[0011] Preferably, the spray booth workpiece conveying device further includes a chain protective cover parallel to the conveyor chain and covering the outside and top of the conveyor chain, wherein the outside of the conveyor chain refers to the side away from the substrate; the chain protective cover includes a side protective plate and a top protective plate, the side protective plate is located outside the conveyor chain, and the top protective plate is connected to the upper edge of the side protective plate and extends horizontally above the conveyor chain.

[0012] Preferably, the top protective plate is disposed on the upper side of the support frame.

[0013] Preferably, a telescopic component is connected between the chain guard and the auxiliary guide rail.

[0014] Preferably, the telescopic assembly includes a housing, a slider, a connecting post, and an elastic element. The housing is a cylindrical structure with one open end. The closed end of the housing is fixedly connected to the base plate, and the open end faces the side protective plate. The housing is horizontally arranged and has a rectangular inner cavity inside. The cross-section of the rectangular inner cavity is rectangular, and the axis of the rectangular inner cavity is horizontally arranged. The slider is slidably connected to the rectangular inner cavity along the axis of the rectangular inner cavity. The connecting post is horizontally arranged, with one end fixed to the slider and the other end fixed to the side protective plate. The elastic element is sleeved on the connecting post, with one end abutting against the slider and the other end abutting against the inner side of the open end of the housing.

[0015] Preferably, the support column is threadedly connected to the support frame; the support frame is densely covered with threaded holes, and a stud is integrally formed at the lower end of the support column, the stud being threadedly engaged with the threaded holes.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. Firstly, compared to existing technologies, the conveyor chain is less prone to vertical swaying due to the support of the conveyor chain support groove, and it is also less prone to horizontal swaying due to the restriction on both sides of the conveyor chain support groove. Therefore, the conveyor support can transport materials more stably, which in turn allows the plate-shaped workpieces on the conveyor support to have a more stable painting environment, resulting in a more uniform paint surface.

[0018] 2. Secondly, the frame structure of the support frame allows excess paint to flow into the paint collection pool below, preventing it from accumulating and sticking to the workpiece; furthermore, the support pillars allow the workpiece to be higher than the support frame, preventing it from contacting the support frame, so that even if paint drips along the support frame, it will not leave flow marks on the workpiece; the comprehensive design allows plate-shaped workpieces to have good painting quality, with uniform paint spraying and no accumulation or flow marks.

[0026] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0027] Example 1:

[0028] A spray booth workpiece conveying device, as described in the reference Figure 1The conveying device is installed on the frame of the production line. The workpiece conveying device in the spray booth includes a conveyor chain 1, a conveyor chain support groove 2, and a conveyor bracket 3. The conveyor chain 1 is arranged horizontally in a straight line. One conveyor chain 1 can be used, but two conveyor chains 1 arranged symmetrically side by side are preferred. The conveyor chain support groove 2 is installed horizontally on the frame and supports the conveyor chain 1 below it along the extension direction of the conveyor chain 1. The groove opening of the conveyor chain support groove 2 faces upward and supports the conveyor chain 1 below and on both sides. The conveyor bracket 3 is set horizontally between the two conveyor chains 1. The two sides of the conveyor bracket 3 are connected to the conveyor chain 1 respectively. The frame is equipped with a motor and sprocket for driving the conveyor chain 1.

[0029] By adopting the above settings, during use, the workpiece 7 is first neatly placed on the conveyor support 3. Then, the motor and sprocket start to drive the conveyor chain 1. The conveyor chain 1 drives the workpiece 7 to move towards the spray booth until the workpiece 7 is conveyed into the spray booth. The spray gun in the spray booth sprays paint on the surface of the workpiece 7 by reciprocating movement. After the painting is finished, the conveyor chain 1 moves backward to convey the workpiece 7 to the position where the workpiece 7 was placed. The staff takes down the workpiece 7 that has been painted and places the next batch of workpiece 7 to be painted.

[0030] Compared with existing technologies, the conveyor chain 1 is less prone to vertical swaying due to the support of the conveyor chain support groove 2, and it is also less prone to horizontal swaying due to the restriction on both sides of the groove opening of the conveyor chain support groove 2. Therefore, the conveyor support 3 can carry out the conveying more stably, which in turn allows the plate-shaped workpiece 7 on the conveyor support 3 to have a more stable painting environment and form a more uniform paint surface.

[0031] Meanwhile, the installation of the conveyor support 3 also makes the conveying of workpiece 7 more stable. If workpiece 7 is placed directly on the conveyor chain 1, the movement of the links of the conveyor chain 1 will still be relatively flexible, with slight vertical displacement, which will affect the stability of the conveying. However, after the installation of the conveyor support 3, the span of the conveyor support 3 connecting to the conveyor chain 1 is larger and the weight is heavier, so it is less affected by the vertical movement of the links. Compared with placing workpiece 7 directly on the conveyor chain 1 for conveying, it will be much more stable.

[0032] There are multiple conveyor supports 3, which are installed sequentially on the conveyor chain 1 along the direction of the frame. The conveyor support 3 includes a rectangular support frame 31 and several pillars 32 vertically fixed on the support frame 31. The support frame 31 includes four longitudinal support rods parallel to the conveyor chain 1 and two transverse support rods perpendicular to the longitudinal support rods. The two transverse support rods are respectively fixedly connected to the two ends of the four longitudinal support rods. Several pillars 32 are installed at intervals on the longitudinal support rods and transverse support rods, and the upper ends of the several support rods are at the same horizontal height.

[0033] By adopting the above configuration, two rows of plate-shaped workpieces 7 can be placed side by side, and all plate-shaped workpieces 7 can form a neat, uniform surface, which is conducive to efficient overall painting. Secondly, the frame structure of the support frame 31 allows excess paint to flow into the paint collection pool below, preventing it from accumulating and sticking to the workpieces 7. Furthermore, the support column 32 ensures that the workpieces 7 are higher than the support frame 31 and do not contact the support frame 31, so even if paint drips along the support frame 31, it will not form flow marks on the workpieces 7. The comprehensive design enables the plate-shaped workpieces 7 to have good painting quality, with uniform painting and no accumulation or flow marks.

[0034] Example 2:

[0035] A spray booth workpiece conveying device, as described in the reference Figure 2 , Figure 3 The difference between this embodiment and the first embodiment is that it also includes an auxiliary guide rail 4 that is parallel to the conveyor chain 1 and supported below the conveyor support 3. The auxiliary guide rail 4 is horizontally installed on the frame and fits against the side of the conveyor chain support groove 2.

[0036] The auxiliary guide rail 4 can work with the conveyor chain 1 to support the conveyor bracket 3; at the same time, the auxiliary guide rail 4 fits against the side of the conveyor chain support groove 2, which makes the conveyor chain support groove 2 more stable; the combined effect makes the support and conveying of the workpiece 7 by the conveyor bracket 3 more stable.

[0037] The auxiliary guide rail 4 includes a base plate 41 and an edge 42. The base plate 41 is fixed to the frame and its surface is in contact with the side of the conveyor support groove 2. The edge 42 is integrally formed on the upper edge of the base plate 41 and is horizontally positioned and supported below the conveyor bracket 3. The base plate 41 provides good stability to the conveyor support groove 2, and the edge 42 provides good auxiliary support to the conveyor bracket 3.

[0038] A spray booth workpiece conveying device further includes a chain guard 5 parallel to the conveyor chain 1 and covering the outside and top of the conveyor chain 1. The outside of the conveyor chain 1 refers to the side away from the substrate 41. The chain guard 5 includes a side guard plate 51 and a top guard plate 52. The side guard plate 51 is located outside the conveyor chain 1, and the top guard plate 52 is integrally formed on the upper edge of the side guard plate 51 and extends horizontally above the conveyor chain 1.

[0039] In actual production, the exposed conveyor chain 1 is constantly affected by the paint spraying from the spray gun. When a lot of paint condenses between the links of the conveyor chain 1, it will affect the transmission of the conveyor chain 1. The chain guard 5, specifically the top guard plate 52 and the side guard plate 51, can prevent the paint sprayed from the top and outside from entering the conveyor chain 1. As for the paint in the inner direction, it is blocked by the workpiece 7 and will not affect the conveyor chain 1.

[0040] Meanwhile, the top protective plate 52 is set on the upper side of the support frame 31. With the support frame 31 supported by the lower side of the edge 42 and restricted by the top protective plate 52, the transmission process will be more stable.

[0041] Example 3:

[0042] A spray booth workpiece conveying device, as described in the reference Figure 4 , Figure 5 The difference between this embodiment and embodiment two is that a telescopic component 6 is connected between the chain guard 5 and the auxiliary guide rail 4, and the chain guard 5 is installed on the auxiliary guide rail 4 through the telescopic component 6.

[0043] By adopting the above settings, when the telescopic component 6 is in the extended state, the chain guard 5 can move away from the auxiliary guide rail 4, thereby exposing the conveyor chain 1, which makes it convenient for staff to lubricate and maintain the conveyor chain 1 and clean oil stains; conversely, when the telescopic component 6 is in the retracted state, the chain guard 5 keeps the conveyor chain 1 covered and protected.

[0044] Specifically, the telescopic component 6 includes a housing 61, a slider 62, a connecting post 63, and an elastic element 64. The housing 61 is a cylindrical structure with one open end. The closed end of the housing 61 is fixedly connected to the base plate 41, and the open end faces the side protective plate 51. The housing 61 is horizontally arranged, and a rectangular inner cavity 611 is provided inside the housing 61. The cross-section of the rectangular inner cavity 611 is rectangular, and the axis of the rectangular inner cavity 611 is horizontally arranged. The slider 62 is slidably connected to the rectangular inner cavity 611 along the axis direction. The connecting post 63 is horizontally arranged, with one end fixed to the slider 62 and the other end fixed to the side protective plate 51. The elastic element 64 can be a compression spring. The elastic element 64 is sleeved on the connecting post 63, with one end of the elastic element 64 abutting against the slider 62 and the other end abutting against the inner side of the open end of the housing 61.

[0045] With the above configuration, under normal conditions, under the elastic action of the elastic element 64, the slider 62 slides to the closed end of the housing 61, the connecting post 63 is mostly located inside the housing 61, the side protective plate 51 is relatively close to the base plate 41, and the top protective plate 52 is located above the conveyor chain 1 to shield and protect it. During maintenance, pulling the side protective plate 51 can compress the elastic element 64, so that most of the connecting post 63 is located outside the housing 61, the side protective plate 51 is relatively far away from the base plate 41, and the top protective plate 52 is away from the top of the conveyor chain 1. This allows the staff to more easily lubricate and maintain the conveyor chain 1 and clean the oil stains.

[0046] Example 4:

[0047] A spray booth workpiece conveying device, as described in the reference Figure 6The difference between this embodiment and embodiment one is that the support column 32 is threadedly connected to the support frame 31; specifically, the support frame 31 is densely covered with threaded holes 311, and the lower end of the support column 32 is integrally formed with a stud 321, which is threadedly engaged with the threaded holes 311.

[0048] By adopting the above settings, the installation position of the support column 32 can be adjusted on the support frame 31, and the position of the support column 32 can be adaptively adjusted according to the different sizes of the plate-shaped workpiece 7 to be painted, so that the spray booth workpiece conveying device can be used for more types of plate-shaped workpieces 7.

[0049] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
