The parts to be processed conveyed to the inclined conveying chain are prone to collide with each other, causing the position of the parts to be processed to change, thereby affecting the subsequent paint spraying and possibly causing uneven paint spraying. SUMMARY

[0006] In one embodiment, the convex surface is a circular arc surface, and the concave surface is a circular arc surface matching the convex surface.
[0007] In one embodiment, the adjacent two convex surfaces are connected by a circular arc, and the adjacent two concave surfaces are connected by a circular arc.
[0008] In one embodiment, the convex surface is at least four.
[0009] In one embodiment, the hook further comprises a second connecting piece arranged below the first connecting piece, the hanging head is located between the first connecting piece and the second connecting piece, and the hook portion is arranged at a position corresponding to the hanging piece at the bottom of the second connecting piece.
[0010] In one embodiment, the first connecting piece and the second connecting piece are two connecting plates arranged in parallel, and the two connecting plates are detachably connected by fasteners.
[0011] In one embodiment, the fixing piece comprises two mounting plates arranged oppositely, the mounting plates comprise fixing segments at two ends and mounting segments located between the two fixing segments, the two mounting plates are fixedly connected by the fixing segments at two ends respectively, the mounting segments of the two mounting plates are outwardly protruded to have an accommodation space between the two mounting segments, and the upper end of the cantilever is pivotably arranged on the two mounting segments by a pivot, and the upper end of the cantilever can swing in the accommodation space.
[0012] According to another aspect of the present application, a conveying device is provided, comprising: a conveying chain conveying in a preset direction; and a hook assembly fixedly arranged on the conveying chain, the hook assembly being the hook assembly described above.

DETAILED DESCRIPTION
[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0028] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
[0029] It should be noted that the terms "first," "second," and the like in the specification and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate for the embodiments of the present invention described herein. In addition, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or apparatuses.
[0030] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.
[0031] like Figures 1 to 7 As shown, in this embodiment, the hook assembly includes: a fixing member 10, a hanging member 20, and a hook 30. The hanging member 20 includes a cantilever 21 and a hanging head 22 provided at the end of the cantilever 21. The upper end of the cantilever 21 is pivotally provided on the fixing member 10. The hook 30 includes a first connecting member 31 and a hook portion 32 fixedly provided on the first connecting member 31. The first connecting member 31 has an avoidance hole 311. The cantilever 21 is provided in the avoidance hole 311 and can rotate circumferentially in the avoidance hole 311. The avoidance hole 311 of the first connecting member 31 is provided with a matching structure 33. The first connecting member 31 is hung on the hanging head 22 through the matching structure 33. The supporting surface of the matching structure 33 of the hanging head 22 has multiple convex surfaces 221 of the same shape arranged in the circumferential direction. The matching structure 33 has a concave surface 331 corresponding to the multiple convex surfaces 221.
[0032] By applying the technical solution of this embodiment, since the upper end of the cantilever 21 is pivotally mounted on the fixing member 10, even if the fixing member 10 moves to the inclined section of the conveyor chain, the cantilever 21 will be vertically downward under the action of gravity, ensuring that the parts to be processed on each hook assembly on the inclined conveyor chain remain in a vertical state, reducing the probability of collision between two adjacent parts to be processed. In addition, even if there is a collision between two adjacent parts to be processed, since the convex surface 221 of the suspension head 22 cooperates with the concave surface 331 of the matching structure 33, that is, in the circumferential direction, the convex surface 221 will stop the concave surface 331, thereby preventing the matching structure 33 from rotating relative to the suspension head 22, thereby preventing the hook portion 32 from being displaced in the circumferential direction, and ultimately preventing the parts to be processed from rotating unexpectedly, thereby ensuring the quality of subsequent painting. Finally, by applying the technical solution of this embodiment, during the hooking process, the matching structure 33 can be manually rotated according to actual conditions to ensure that the direction of the parts hooked by the hook portion 32 is convenient for subsequent painting.
[0033] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, in this embodiment, the convex surface 221 is an arc surface, and the concave surface 331 is an arc surface adapted to the convex surface 221. The above structure allows the operator to rotate the matching structure 33 to adjust the direction of the hook portion 32 more smoothly.
[0034] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, in this embodiment, an arc transition is formed between two adjacent convex surfaces 221, and an arc transition is formed between two adjacent concave surfaces 331. The above structure further makes it smoother for the operator to rotate the matching structure 33 to adjust the direction of the hook portion 32.
[0035] In this embodiment, there are four convex surfaces 221. This structure allows the hook portion 32 to be positioned at 0°, 90°, 180°, and 270°, making the hanging method of the parts to be processed more flexible. In other words, different parts can be hung at different angles according to actual needs, so that different parts can be painted evenly. Of course, in other embodiments not shown in the figures, more convex surfaces can be provided, and the specific number is determined according to actual needs.
[0036] like Figure 1 、 Figure 3 and Figure 4As shown, in this embodiment, the hook 30 further includes a second connecting member 34 disposed below the first connecting member 31, the suspension head 22 is located between the first connecting member 31 and the second connecting member 34, and the hook portion 32 is disposed at a position corresponding to the suspension member 20 at the bottom of the second connecting member 34. The above structure enables the hook portion 32 to be coaxial with the suspension head 22, thereby achieving a miniaturized design of the hook assembly.
[0037] like Figure 1 、 Figure 3 and Figure 4 As shown, in this embodiment, the first connecting member 31 and the second connecting member 34 are two parallel connecting plates, which are detachably connected by a fastener 35. This structure allows the suspension member 20 to be a one-piece structure, thereby reducing the number of parts. Specifically, during installation, the suspension member 20 is first inserted from bottom to top onto the first connecting member 31, then the first connecting member 31 and the second connecting member 34 are connected via the fastener 35, and finally, the suspension member 20 is pivotally connected to the fixed member 10.
[0038] like Figure 1 and Figure 5 As shown, in this embodiment, the fixing member 10 includes two mounting plates 11 arranged opposite each other. The mounting plates 11 include fixing sections 111 at both ends and a mounting section 112 located between the two fixing sections 111. The two mounting plates 11 are fixedly connected by the fixing sections 111 at both ends. The mounting sections 112 of the two mounting plates 11 protrude outward to form an accommodating space 113 between the two mounting sections 112. The upper end of the cantilever 21 is pivotally mounted on the two mounting sections 112 via the pivot 12, and the upper end of the cantilever 21 can swing within the accommodating space 113. The above structure can not only realize the connection between the fixing member 10 and the suspension member 20, but also provide space for the suspension member 20 to swing.
[0039] This application also provides a conveying device (not shown). An embodiment of the conveying device includes a conveyor chain and a hook assembly. The conveyor chain conveys along a predetermined direction; the hook assembly is fixedly mounted on the conveyor chain and is the aforementioned hook assembly. Because the aforementioned hook assembly improves the quality of part painting, a conveying device incorporating the hook assembly also exhibits these advantages.
[0040] In this embodiment, the conveying chain includes a horizontal conveying chain and an inclined conveying chain that tilts up and down.
[0041] This application also provides a production line (not shown). An embodiment of the production line according to this application includes: a processing chamber, a paint spraying device, and a conveying device. The paint spraying device is disposed within the processing chamber. The conveying device is the aforementioned conveying device, and its conveyor chain passes through the processing chamber. Because the aforementioned conveying device has the advantage of improving the quality of part painting, a production line incorporating it also has the aforementioned advantages.
[0042] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.
[0043] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0044] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.
[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
