[0038] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides a topcoat auxiliary tool for connecting to a workpiece to be painted, the topcoat auxiliary tool comprises a connecting plate 1, a plurality of positioning members 2 and a locking mechanism 3, the connecting plate 1 has a first surface 11 and a second surface 12, the first surface 11 is configured to be at least partially magnetically attracted, that is, the connecting plate 1 can be partially or entirely made of iron or magnetic materials that can be magnetically attracted, so as to provide a magnetic attraction operation for an external device, with a large operable area and convenient operation. The positioning members 2 are arranged on the connecting plate 1, and a plurality of positioning members 2 are arranged along the circumference of the second surface 12, the positioning members 2 are used to connect to the workpiece to be painted and to circumferentially limit the second surface 12 and the workpiece to be painted. The locking mechanism 3 is arranged on the connecting plate 1, and the locking mechanism 3 is used to be detachably connected to the workpiece to be painted, and the locking mechanism 3 can abut and fix the second surface 12 and the workpiece to be painted.

[0039] With such arrangement, during the topcoat process, the topcoat auxiliary tool can be connected to the workpiece to be painted, that is, the multiple positioning parts 2 on the connecting plate 1 are connected to the workpiece to be painted, and the adjacent positioning parts 2 can be positioned with each other, thereby reducing the movement or rotation of the connecting plate 1 on the surface of the workpiece to be painted, and the locking mechanism 3 can be connected and fixed to the workpiece to be painted to abut and fix the second surface 12 of the connecting plate 1 against the workpiece to be painted, thereby avoiding the connection plate 1 and the workpiece to be painted from being separated from each other, and the connection is firm. The topcoat robot and other processing equipment can drive the topcoat auxiliary tool and the workpiece to be painted to move together by magnetically attracting the first surface 11 of the connecting plate 1, so as to place the workpiece to be painted to the desired topcoat angle or position, such as opening or closing the door, and part or all of the first surface 11 of the connecting plate 1 can be magnetically attracted, with a large operating area and convenient operation, thereby reducing the requirements of the topcoat process on the material of the workpiece to be painted itself, and solving the problem of inconvenient door opening operation during the topcoat spraying process of aluminum car doors in the related technology.

[0040] The topcoat auxiliary tool of this embodiment can be applied to the topcoat operation of the vehicle door. Specifically, the part to be painted can be configured as a vehicle door, which is a hollow shell structure. The topcoat auxiliary tool can be installed on the side of the vehicle door facing the driver's compartment. The length and width of the connecting plate 1 can be equal to the size of the vehicle door, so that the connecting plate 1 can push and pull the vehicle door. A plurality of holes or slots are preset on the vehicle door for installation and use with the topcoat auxiliary tool.

[0041] like Figure 1 to Figure 2 As shown, in some embodiments, three positioning members 2 are provided, and adjacent positioning members 2 are spaced apart, and the three positioning members 2 are arranged in a triangle. In this arrangement, the three positioning members 2 are located on the second surface 12, and any two of the three can limit the relative movement or rotation of the other on the workpiece to be painted, thereby reducing the rotation or movement of the connecting plate 1 and the workpiece to be painted in all directions along the first surface 11. Not only is the structure simple and the installation is convenient, but also the stability of the positioning connection between the connecting plate 1 and the workpiece to be painted is improved.

[0042] like Figure 1 to Figure 2 As shown, in some embodiments, the positioning member 2 is configured as a positioning pin 21 or a cylinder 22, and the plurality of positioning members 2 are one of the positioning pin 21 and the cylinder 22 or a combination of both. In this way, the plurality of positioning members 2 can all adopt the positioning pin 21 structure, or the plurality of positioning members 2 can all adopt the cylinder 22 structure, and the positioning members 2 are unified, and are easy to process and install. Alternatively, one or more of the plurality of positioning members 2 can adopt the positioning pin 21 structure, and another one or more can adopt the cylinder 22 structure, which can not only make the positioning connection stable, but also can adopt different positioning structures, thereby forming a foolproof effect and avoiding mis-installation or wrong installation.

[0043] In this embodiment, taking three positioning members 2 as an example, a positioning member 2 located at the top of the connecting plate 1 can be configured as a cylinder 22, and two positioning members 2 located at the bottom of the connecting plate 1 can be configured as positioning pins 21. During installation, the cylinder 22 can be first plugged into the workpiece to be painted. The connection is quick and can be quickly positioned. Then the two positioning pins 21 are connected to the workpiece to be painted, and other forms of limiting fixation such as plug-in or snap-on can be performed. The installation is convenient.

[0044] like Figure 1 to Figure 2 As shown, in some embodiments, the positioning pin 21 includes a pin rod 211 and a hook 212 connected to each other. The pin rod 211 is rotatably connected to the connecting plate 1, and the hook 212 is used to engage with the workpiece to be painted. With this arrangement, the pin rod 211 can support the hook 212 from the connecting plate 1 at a certain distance, so as to facilitate the hook 212 to be extended into the interior of the workpiece to be painted for connection and engagement. The rotation of the pin rod 211 can drive the hook 212 to rotate, so that the hook 212 can be hooked at different positions.

[0045] In this embodiment, the pin rod 211 passes through the connecting plate 1, and two hooks 212 may be provided. The two hooks 212 are fixed at both ends of the pin rod 211, and the two hooks 212 are respectively located on both sides of the connecting plate 1, so as to facilitate the fixing on both sides of the connecting plate 1, which is convenient for multi-position fixing and also convenient for users to hold and operate.

[0046] like Figure 1 to Figure 2 As shown, in some embodiments, the positioning pin 21 also includes a gasket 213, which is sleeved on the pin rod 211. The gasket 213 is used to abut between the second surface 12 and the surface of the part to be painted. With this configuration, the gasket 213 can be but is not limited to an elastic material or a flexible material. The gasket 213 abuts between the second surface 12 of the connecting plate 1 and the surface of the part to be painted, and can form an elastic buffer support between the connecting plate 1 and the surface of the part to be painted, thereby reducing the rigid contact between the connecting plate 1 and the surface of the part to be painted, and causing damage to the surface of the painted part.

[0047] like Figures 2 to 4 As shown, in some embodiments, the locking mechanism 3 includes a housing 31, a locking rod 32 and an elastic member 33. The housing 31 is connected to the connecting plate 1 so that the housing 31 is fixed with the connecting plate 1 as support. The locking rod 32 is slidably connected to the housing 31, and the locking rod 32 can be extended or retracted to the housing 31, that is, the locking rod 32 can be slidably arranged on the housing 31, and the sliding direction of the locking rod 32 can be arranged along the vertical direction of the axis of the positioning member 2. The elastic member 33 is arranged between the housing 31 and the locking rod 32, and the elastic member 33 is configured to be able to give the locking rod 32 an elastic force so that the locking rod 32 extends out of the housing 31.

[0048] With such arrangement, the locking mechanism 3 can have a locked state and an open state. When the locking mechanism 3 is in the locked state, the locking rod 32 can slide relative to the housing 31 and extend out of the housing 31 under the elastic force of the elastic member 33, and the end of the locking rod 32 can be fixedly connected to the part to be painted, so as to lock and fix the connecting plate 1 and the part to be painted. When the locking mechanism 3 needs to be opened, the locking rod 32 can squeeze the elastic member 33 under the action of external force, and the elastic member 33 undergoes elastic deformation, and the locking rod 32 can retract into the part to be painted. At this time, the connecting plate 1 can be installed on the part to be painted or can be removed from the part to be painted. After the external force is removed, the elastic member 33 recovers and the locking rod 32 can extend out of the housing 31 again under the elastic force of the elastic member 33, and the locking mechanism 3 returns to the locked state, so that the connecting plate 1 and the part to be painted can be quickly locked, and the operation is convenient.

[0049] In this embodiment, the elastic member 33 may be, but is not limited to, a spring or a sleeve made of elastic material. One end of the elastic member 33 may be fixedly connected to the locking rod 32 , and the other end may be fixedly connected to the housing 31 .

[0050] like Figure 3 to Figure 4 As shown, in some embodiments, the elastic member 33 is sleeved on the locking rod 32, and a limiting flange 322 is provided on the locking rod 32. The elastic member 33 abuts between the limiting flange 322 and the inner wall of the shell 31. With such a configuration, when the locking rod 32 moves under the action of an external force, it can drive the limiting flange 322 to squeeze the elastic member 33. After the external force is removed, the elastic member 33 restores its deformation and can push the limiting flange 322 to move, thereby driving the locking rod 32 to move. The limiting flange 322 can provide a force application point for the elastic member 33, which facilitates the interaction between the elastic member 33 and the locking rod 32, and also facilitates the separate installation of the elastic member 33 and the locking rod 32. The installation and disassembly are convenient, and the maintenance and replacement are convenient.

[0051] like Figure 3 to Figure 4 As shown, in some embodiments, the lock rod 32 is provided with a first gripping portion 321, the first gripping portion 321 extends through the housing 31, and the first gripping portion 321 is configured to be able to drive the lock rod 32 to slide under the action of an external force. In this way, the first gripping portion 321 is used for a user to perform a gripping operation to apply an external force. The first gripping portion 321 can be, but is not limited to, a rod-shaped structure, the first gripping portion 321 is fixedly connected to the lock rod 32, the first gripping portion 321 can extend out of the housing 31 and be slidably connected to the housing 31, or the housing 31 has an opening, the opening is used to provide a movement space for the first gripping portion 321, reduce the positional interference between the first gripping portion 321 and the housing 31, and facilitate force application.

[0052] like Figure 1 to Figure 2As shown, in some embodiments, the paint auxiliary tool further includes a second gripping portion 13, which is connected to the connecting plate 1 and is located on the first surface 11. In this way, the second gripping portion 13 can be held by the user to facilitate installation and removal operations between the paint auxiliary tool and the workpiece to be painted. Moreover, when the paint auxiliary tool is connected to the workpiece to be painted, the second gripping portion 13 can be held by the user, and the user can manually push and pull the workpiece to be painted through the second gripping portion 13, and the position adjustment is convenient to use.

[0053] In this embodiment, the second holding portion 13 may be, but is not limited to, a handle or a groove, and may be selected according to the user's holding needs.

[0054] like Figure 1 to Figure 2 As shown, in some embodiments, the connecting plate 1 is configured as an L-shaped plate, and the size of the bending part of the L-shaped plate is larger than the size of the two arms of the L-shaped plate. In this way, compared with a plate body of the same size as the part to be painted, the connecting plate 1 is designed as an L-shaped plate. It can reduce the size and volume of the connecting plate 1 while meeting the needs of connection and use, and it is easier to install and use.

[0055] like Figure 1 to Figure 2 As shown, in some embodiments, a hollow hole 14 is provided on the connecting plate 1. The hollow hole 14 can not only reduce the weight of the connecting plate 1, but also serve as a window when the connecting plate 1 is installed and used, so as to facilitate the observation and adjustment of the installation process and position between the positioning member 2, the locking member and the part to be painted, and is easy to use.
