[0042] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be noted that, unless otherwise specified, the term "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front," "rear," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention depending on the specific circumstances.

[0045] The present invention provides a workpiece transport chain, comprising a vertical chain group 1, a translation chain group 2, a first hook 3, a second hook 4, a gear group 5, and a hanger 6. The vertical chain group 1 and the translation chain group 2 are both closed-loop structures. The turning point of the vertical chain group 1 is connected to the gear group 5. The two ends of the translation chain group 2 are respectively meshed with the two gear groups 5. The end of the translation chain group 2 corresponds to the vertical section of the vertical chain group 1.

[0046] There are multiple first hooks 3 and multiple second hooks 4, all of which are connected to the side walls of the vertical chain group 1, and all of which are connected to the vertical chain group 1. The spacing between two adjacent first hooks 3 is greater than the spacing between two adjacent second hooks 4.

[0047] The hanger 6 can be hung on the first hook 3 or the second hook 4. The present invention provides a workpiece transport chain, in which a workpiece 40 is hung on the hanger 6, and the hanger 6 can be hung on the first hook 3. When the vertical chain group 1 is in operation, the workpiece 40 on the first hook 3 can be transported and moved. When the vertical chain group 1 moves the workpiece 40 to the input end of the translation chain group 2, due to the setting of the second hook 4 and the position setting of the end of the translation chain group 2 and the vertical section of the vertical chain group 1, the workpiece 40 on the first hook 3 can be transferred to the second hook 4. Since the spacing between two adjacent first hooks 3 is greater than the spacing between two adjacent second hooks 4, when some of the workpieces 40 on the vertical chain group 1 are transferred to the translation chain group 2, the spacing between the two adjacent workpieces 40 will also change. Since the vertical chain group 1 and the gear group 5 are meshed and connected by the chain gear, the direction of the vertical chain group 1 can be changed, so that the vertical chain group 1 can be vertically lifted and lowered, solving the technical problem in the prior art that the spacing between two workpieces cannot be changed during the process of transporting workpieces.

[0048] As an optional embodiment, the vertical chain group 1 includes two vertical chains, the two vertical chains correspond to each other and are both connected to a first hook 3, the ends of the hanger 6 are respectively hung on the two corresponding first hooks 3 on the two vertical chains, each vertical chain is connected to a plurality of gear groups 5, the gear groups 5 are connected to the bracket 20, and one of the gear groups 5 is connected to a driving device 30, which is used to drive the vertical chain to operate;

[0049] The translation chain group 2 includes two translation chains, which correspond to each other and are both connected to a second hook 4. The two ends of the hanger 6 are respectively hung on the two corresponding second hooks 4 on the two translation chains. The distance between the two translation chains is smaller than the distance between the two vertical chains. This is to facilitate the transfer of the workpiece 40. Each translation chain is connected to two gear groups 5, which are connected to the bracket 20, and one of the gear groups 5 is connected to a driving device 30, which is used to drive the translation chain to operate.

[0050] As an optional embodiment, the first hook 3 includes a connecting shaft 31 and a hook group. One end of the connecting shaft 31 is connected to the vertical chain, and the other end of the connecting shaft 31 is rotatably connected to the hook group. This is to ensure that the workpiece 40 will always remain in a vertical state under the action of gravity during the movement of the vertical chain group 1, and the hook group can hook the end of the hanger 6.

[0051] As an optional embodiment, the hook group includes a connecting plate 32, a V-shaped seat 33, a washer 34 and a cotter pin 35. The other end of the connecting shaft 31 is connected to the washer 34, the connecting plate 32 and the cotter pin 35 in sequence. The washer 34 is located between the connecting plate 32 and the vertical chain to avoid wear. The cotter pin 35 is used to limit the connecting plate 32 from being separated from the connecting shaft 31, and the connecting shaft 31 is rotatably connected to the connecting plate 32. The connecting plate 32 is fixedly connected to the V-shaped seat 33. The end of the diamond rod 61 on the hanger 6 can be placed in the V-shaped seat 33, which can prevent the diamond rod 61 from rotating relative to the V-shaped seat 33 and maintain the stability of the workpiece 40.

[0052] As an optional embodiment, the second hook 4 includes two support plates 41, and the two support plates 41 are respectively connected to the two sides of the translation chain group 2, that is, the two support plates 41 are respectively connected to the two sides of the translation chain; a V-shaped groove 411 is provided on the support plate 41, and the end of the diamond rod 61 on the hanger 6 can be placed in the V-shaped groove 411, which can prevent the diamond rod 61 from rotating relative to the V-shaped groove 411, thereby maintaining the stability of the workpiece 40.

Under the operation of the workpiece transport chain, a workpiece 40 can sequentially pass through the powder booth 7, powder baking oven chamber 8, paint spraying booth 9, and paint baking oven chamber 10, thereby sequentially undergoing the processes of spraying a base powder, baking the powder, spraying a topcoat, and baking the paint. The ends of the support 20 are respectively configured as a loading area and a unloading area, with the loading area being adjacent to the powder booth 7 and the unloading area being adjacent to the paint baking oven chamber 10.

[0054] As an optional embodiment, the powder room 7 includes a powder box 71, a powder robot 72, a first lifting and rotating mechanism 73 and a powder pulse recovery cabinet 74. The powder robot 72 is located on one side of the powder box 71. The powder robot 72 can spray the base powder on the workpiece 40 in the powder box 71. The first lifting and rotating mechanism 73 is located above the powder box 71. A part of the vertical chain group 1 is located on the top of the powder box 71. The first lifting and rotating mechanism 73 can hook the hanger 6 on the vertical chain group 1. The first lifting and rotating mechanism 73 can lift the hanger 6 upward and then rotate it so that the hanger 6 first detaches from the first hook 3 and then rotates the workpiece 40, so that every part of the workpiece 40 is sprayed with base powder. The other side of the powder box 71 is connected to the powder pulse recovery cabinet 74. The powder pulse recovery cabinet 74 is used to recycle the base powder in the powder box 71 to avoid polluting the environment.
