[0045] Embodiment one

[0046] This embodiment relates to a spraying tool for supporting a vehicle component when spraying the vehicle component of plastic material, and aims to improve the safety of vehicle component spraying by optimizing the structure of the spraying tool.

[0047] In combination Figures 1 to 5 As shown in the figure, in the overall structure, the spraying tool in this embodiment includes a mounting portion 1, a supporting portion 2, and a conductive portion 3.

[0048] The mounting portion 1 is used to mount the spraying tool on an external carrier, the supporting portion 2 is connected to the mounting portion 1 and is used to support the vehicle component from the back, and the supporting portion 2 can shield the back of the vehicle component when the vehicle component is sprayed. The conductive portion 3 is provided on the supporting portion 2 and can pass from the back of the vehicle component to the front of the vehicle component, and the conductive portion 3 can ground the paint layer formed by spraying when the front of the vehicle component is sprayed.

[0049] As set forth above, in the spraying tool in the embodiment, the installation part 1 is arranged to facilitate the assembly of the spraying tool on the external carrier, the support part 2 is arranged to support the vehicle part from the back, thereby improving the stability of the vehicle part during spraying and shielding the back of the vehicle part to facilitate the spraying of the vehicle part, and the conductive part 3 is arranged to ground the paint layer formed by spraying, thereby facilitating the release of excess charges of the paint layer and avoiding the problem of electrostatic breakdown, so as to improve the safety of the spraying of the vehicle part.

[0050] Specifically, in the embodiment, as an exemplary structure, the installation part 1 of the spraying tool comprises a main beam 101 and a connecting unit 102 arranged on the main beam 101. Figures 1 to 3 As shown in the figure, in order to better assemble the spraying tool on the external carrier, the installation part 1 of the spraying tool in the embodiment comprises a main beam 101 and a connecting unit 102 arranged on the main beam 101. The main beam 101 can be fixed on the external carrier, and the support part 2 is connected to the connecting unit 102. Thus, the installation part 1 comprises the main beam 101 and the connecting unit 102, which facilitates the connection and fixation of the support part 2 and the assembly of the spraying tool on the external carrier. The arrangement of the main beam 101 facilitates the improvement of the structural strength of the spraying tool and facilitates the design implementation.

[0051] In more detail, in the embodiment, in order to better connect the support part 2, as shown in the figure, the connecting unit 102 in the embodiment comprises a first connecting piece 1021 and a second connecting piece 1022 arranged on the main beam 101. Figures 1 to 3 The first connecting piece 1021 extends from the main beam 101 to the top of the support part 2 and is connected to the top of the support part 2, and the second connecting piece 1022 extends from the main beam 101 to the bottom of the support part 2 and is connected to the bottom of the support part 2.

[0052] In addition, in the connecting unit 102 of the embodiment, a plurality of third connecting pieces 1023 are connected between the first connecting piece 1021 and the second connecting piece 1022, and a fourth connecting piece 1024 is also connected between adjacent third connecting pieces 1023.

[0053] Thus, the connecting unit 102 comprises the first connecting piece 1021, the second connecting piece 1022, the third connecting piece 1023 and the fourth connecting piece 1024, is connected to the top of the support part 2 through the first connecting piece 1021, is connected to the bottom of the support part 2 through the second connecting piece 1022, connects the first connecting piece 1021 and the second connecting piece 1022 through the third connecting piece 1023, and connects the third connecting piece 1023 through the fourth connecting piece 1024. The embodiment can make the connecting unit 102 form a frame type connection structure, which not only facilitates the improvement of the structural strength of the connecting unit 102, but also facilitates the lightweight design of the spraying tool due to the frame type structure, thereby facilitating the design implementation.

[0054] In the embodiment, the first connecting piece 1021, the second connecting piece 1022, the third connecting piece 1023 and the fourth connecting piece 1024 can be made of iron pipe, for example.

[0055] In addition, as shown in Figures 1 to 5 In the embodiment, the main beam 101 of the spraying tool is provided with a positioning pin 103, which can be inserted into a positioning hole on an external carrier. Through the positioning pin 103, the positioning hole of the external carrier can be matched to realize the positioning of the spraying tool on the external carrier. At the same time, the cooperation of the positioning pin 103 and the positioning hole facilitates the quick assembly of the spraying tool on the external carrier, which is beneficial to design and implementation. In the embodiment, the external carrier can be a base arranged in the spraying area, which is provided with a positioning hole matched with the positioning pin 103. When it is necessary to assemble the spraying tool in the spraying area, the positioning pin 103 can be inserted into the positioning hole.

[0056] The support part 2 in the embodiment supports the back of the vehicle part, can support the vehicle part during spraying, and constrain the vehicle part in the spraying area. The vehicle part in the embodiment is made of plastic material, which can be a deflector plate of a vehicle, for example.

[0057] Specifically, as shown in Figures 1 to 5 The support part 2 in the embodiment includes a profiling plate 201 and a support plate 202 provided on the profiling plate 201. The support plate 202 supports the flange at the edge of the back of the vehicle part and can constrain the position of the vehicle part during spraying. At least part of the profiling plate 201 can abut against the vehicle part, and the profiling plate 201 is used to shield the back of the vehicle part during spraying. Through the arrangement of the profiling plate 201 and the support plate 202, the back of the vehicle part can be shielded by the profiling plate 201 under the premise of ensuring the supporting effect of the spraying tool on the vehicle part, so that the support plate 202 supports the flange of the vehicle part, which is beneficial to improve the supporting effect and make the support more stable.

[0058] More specifically, as shown in Figure 1 , Figure 2 and Figure 4 In order to better protect the vehicle part, the profiling plate 201 in the embodiment is provided with an avoiding hole 203, which is used to avoid the part protruding to the back of the vehicle part, such as the buckle, reinforcing rib and other parts on the vehicle part. Through the arrangement of the avoiding hole 203, the gap between the profiling plate 201 and the back of the vehicle part can be reduced, and the wear of the profiling plate 201 on the vehicle part can be avoided, which is beneficial to design and implementation.

[0059] It is worth mentioning that the back of the vehicle part is involved in the gluing process during use and assembly, so that the back of the vehicle part cannot have paint mist, and the back of the vehicle part needs to be shielded. The profiling plate 201 in the embodiment conforms to the vehicle part, but the profiling part in the embodiment is smaller than the outer contour of the vehicle part when the profiling plate 201 is used. A gap is left between the outer contour of the profiling plate 201 and the outer contour of the vehicle part. Through the setting of the gap, the profiling plate 201 is prevented from exceeding the vehicle part during electrostatic spraying, and the shielding effect of the profiling plate 201 on the back of the vehicle part is ensured.

[0060] In addition, in order to better support the vehicle part, as shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , the support plate 202 in the embodiment is arranged at the edge of the profiling plate 201, and part of the support plate 202 coincides with the edge of the profiling plate 201, so as to improve the connection strength of the support plate 202 and the profiling plate 201. According to the different flanging positions of the vehicle part, the support plate 202 may be provided in multiple numbers on the profiling plate 201. The number of the support plate 202 is determined according to the support requirement of the vehicle part and the number of the back flanging of the vehicle part. The support plate 202 is arranged at the edge of the profiling plate 201, which is convenient for the machining and assembly of the support plate 202. The support plate 202 is provided in multiple numbers on the profiling plate 201, which is convenient for improving the support effect and facilitating the design implementation.

[0061] The conductive part 3 in the embodiment penetrates from the back of the vehicle part to the front of the vehicle part, and can ground the paint layer formed during spraying, so as to release the excess charge generated on the paint layer during the electrostatic spraying process.

[0062] Specifically, as shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , the conductive part 3 in the embodiment includes a conductive rod 301 arranged on the support part 2. The conductive rod 301 penetrates from the back of the vehicle part to the front of the vehicle part through the through hole on the vehicle part, and the conductive rod 301 abuts against the vehicle part to form an electrical connection with the paint layer. Through the setting form of the conductive rod 301 penetrating through the through hole of the vehicle part, the electrical connection between the conductive rod 301 and the paint layer is facilitated, which is helpful for the conduction of the excess charge of the paint layer and facilitates the design implementation.

[0063] In more detail, the conductive rod 301 in the embodiment may, for example, adopt a wedge-shaped structure of an iron block, and of course may also adopt other materials with conductive properties and structural strength in the prior art, so that the conductive rod 301 is in a wedge-shaped structure, facilitating the adaptation of the size of the through hole, and facilitating the insertion of the conductive rod 301 into the through hole and the abutment with the vehicle part.

[0064] In addition, in order to better ground the coating layer, at least part of the mounting portion 1 and at least part of the support portion 2 in the embodiment are made of metal, so that the mounting portion 1 and the support portion 2 are connected to form a conductive path between the conductive portion 3 and the ground. In the embodiment, in order to better conduct, the mounting portion 1 and the support portion 2 may, for example, be made of iron plates, so that the part of the mounting portion 1 and the part of the support portion 2 are made of metal, facilitating the formation of the conductive path between the conductive portion 3 and the ground, so that the electric charge can be conducted through the sequentially connected conductive portion 3, support portion 2 and mounting portion 1, and the structure is simple and conducive to design and implementation. Of course, the conductive portion 3 can also be grounded through a wire harness, so that the wire harness forms a conductive path between the coating layer and the ground.

[0065] The spraying tool of the embodiment is used, and the vehicle part to be sprayed is taken as a front deflector plate of a vehicle. The deflector plate is generally symmetrically arranged in two pieces, so two support portions 2 are arranged on the same main beam 101 of the spraying tool. The main beam 101 is assembled on the grounded base through a positioning pin 103. In order to improve the connection strength of the support portion 2 and the main beam 101, three connection units 102 are connected between each support portion 2 and the main beam 101. Each connection unit 102 is spaced apart and supported at the two ends and the middle of the support portion 2. Each connection unit 102 includes a first connecting piece 1021 connected to the top of the deflector plate, a second connecting piece 1022 connected to the bottom of the deflector plate, a third connecting piece 1023 connected between the first connecting piece 1021 and the second connecting piece 1022 of the same connection unit 102, and a fourth connecting piece 1024 connected between adjacent third connecting pieces 1023.

[0066] The support portion 2 includes a profiling plate 201 and a support plate 202. The profiling plate 201 is shaped according to the shape of the deflector plate, and the outer contour of the profiling plate 201 is smaller than the outer contour of the deflector plate. The support plate 202 is arranged on the profiling plate 201 to support the two sides of the deflector plate. The profiling plate 201 and the support plate 202 are made of iron plates. The conductive rod 301 is a wedge-shaped iron block connected to the support plate 202. In order to ensure that the conductive rod 301 can pass through the through hole on the deflector plate, the conductive rod 301 is inclined to the deflector plate. In use, the flange of the deflector plate is clamped on the support plate 202, and at this time, part of the profiling plate 201 abuts on the deflector plate to suspend the deflector plate on the spraying tool. The deflector plate can be sprayed by the electrostatic spraying equipment.

[0067] The spraying tool in the embodiment is designed as above, through the setting of the mounting part 1, the spraying tool is convenient to assemble on the external carrier, through the setting of the supporting part 2, the vehicle part can be supported on the back, the stability of the vehicle part during spraying is improved, the back of the vehicle part is shielded, the spraying of the vehicle part is facilitated, through the setting of the conductive part 3, the coating layer formed by spraying is grounded, the excess charge of the coating layer is convenient to release, the problem of electrostatic breakdown is avoided, and the safety of the spraying of the vehicle part is improved.
