Description

Technical Field

[0001] The present application relates to, but is not limited to, the field of automobile production technology, and in particular to an automobile exterior spraying tool. Background Art

[0002] In the new era of consumerism, car purchasing habits have significantly shifted, from prioritizing vehicle performance to prioritizing appearance. A vehicle's exterior color significantly impacts its appearance, and more than one color may be required. Therefore, large areas of the vehicle's exterior may require localized, differentiated color spraying. Masking spraying is typically employed: the exterior color is first sprayed, and then areas not requiring a secondary coat are masked with color-separating tape and masking paper. Finally, a high-gloss black finish is applied in a final coat. This process is crucial for masking unpainted areas. Applying the color-separating tape and masking paper is a completely manual process. Improper application of the color-separating tape can result in defects such as jagged, wavy surfaces, paint mist, and butt-joint lines, significantly impacting both pass rate and throughput. Conventional methods typically involve placing the workpiece directly on a workbench and applying the tape. This can easily shift, leading to errors and poor application quality. Furthermore, the workpiece must be moved to adjust the angle of the tape application, making it inconvenient for workers and reducing masking efficiency. Utility Model Content

[0003] In order to solve the above problems, the present application provides an automobile exterior spraying tool, which can facilitate the pasting of color separation tape and masking paper on the spray workpiece, thereby improving the efficiency of the masking process.

[0004] The present application provides an automobile exterior spraying tool, which includes a base frame, a bracket, a connecting assembly and a locking assembly, wherein the bracket is rotatably connected to the base frame, and the bracket is used to support the workpiece to be sprayed; the connecting assembly is arranged on the bracket, and the connecting assembly is used to fix the workpiece to be sprayed on the bracket; the locking assembly is used to lock the relative position of the bracket and the base frame.

[0005] The present application provides an automotive exterior painting tool. A base frame is provided on the tool, the base frame is placed on the ground, and supports the entire automotive exterior painting tool. Furthermore, a bracket is rotatably connected to the base frame, and the bracket supports the workpiece to be sprayed, so that the workpiece to be sprayed can be rotated on the automotive exterior painting tool. Color separation tape and masking paper can be applied to the workpiece from multiple angles. Furthermore, the automotive exterior painting tool includes a connecting assembly, which is used to secure the workpiece to be sprayed to the bracket, so that the workpiece to be sprayed can be fixed to the automotive exterior painting tool. Therefore, displacement of the workpiece to be sprayed relative to the bracket when applying color separation tape and masking paper to the workpiece can be avoided, thereby improving the pass rate and output rate of applying color separation tape and masking paper to the workpiece. Furthermore, the automotive exterior painting tool includes a locking assembly, which is used to lock the relative position of the bracket and the base frame, so that the bracket can be fixed to the base frame and stop rotating when the workpiece to be sprayed is rotated to the appropriate position. Therefore, it is possible to further avoid displacement of the workpiece to be sprayed relative to the base frame when the color separation tape and masking paper are pasted on the workpiece to be sprayed. Compared with the related art in which the workpiece to be sprayed is generally placed directly on the workbench and the tape is directly pasted, the workpiece to be sprayed is easy to shift, easy to make mistakes, and affect the pasting effect, and the workpiece to be sprayed needs to be moved to change the angle of the tape pasting operation, which is inconvenient for the workers to work and has a relatively low efficiency in masking work. The present application uses a rotatable connection between the bracket and the base frame, and the rotation of the bracket avoids the back and forth clamping of the workpiece to be sprayed to achieve the pasting of color separation tape and masking paper at different angles, and the connecting component is provided on the bracket to fix the workpiece to be sprayed on the bracket, and the locking component is used to lock the relative position of the bracket and the base frame, which can enhance the stability of the workpiece to be sprayed installed on the bracket, and facilitate the adjustment of the angle of the workpiece to be sprayed, and can facilitate the pasting of color separation tape and masking paper on the workpiece to be sprayed, further improving the efficiency of the masking link.

The positioning portion is used to abut against the inner raised structure of the workpiece to be sprayed to limit the displacement of the workpiece to be sprayed on the bracket.

[0009] In an implementation provided in the present application, the upper surface of the positioning portion is used to abut against the lower surface of the inner protruding structure of the corresponding workpiece to be sprayed, so as to support the workpiece to be sprayed.

DETAILED DESCRIPTION

[0032] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.

[0033] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0034] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more.

[0035] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0037] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0038] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0039] Under the consumption concept of the new era, people's concept of buying cars has changed significantly, from focusing mainly on vehicle performance to paying more attention to the appearance of the vehicle.

[0040] The color of a vehicle's exterior has a great influence on its appearance. In the design process of many vehicle exteriors, a lot of exterior plastic covering parts are used. This is due to both the need to reduce weight and the need for styling intentions. Therefore, current vehicle designs have bolder innovations in the definition of many exterior colors, materials, and processing techniques (Color Material Finishing, CMF). It is necessary to use large-area all-plastic exterior covering parts, large-area body color spraying, and matching all-plastic retractable sports rear wing. Therefore, the vehicle may need to be sprayed with more than one color, and a large area of body color exterior needs to be locally differentiated in color spraying. Therefore, the dual-color technology of the exterior came into being.

[0041] Because a large area of all-plastic outer covering parts and a large area of body color spraying are required, the bottom surface that matches the all-plastic liftable rear wing needs to change the appearance of this matching surface from body color to a high-gloss black appearance to weaken the bottom pit-shaped matching surface. In order to realize this design scheme, there are generally two technical methods. One is to split the whole component into two parts, spray the two parts into two appearance colors for assembly, but this method increases the assembly steps, increases the processing and time costs, and the structural strength of the assembly will also be reduced. The second is to use the masking spraying method to first spray the entire component with the body color, and then mask and spray other colors. This method allows the parts to be formed in one piece, saving processing and time costs and avoiding the reduction of structural strength.

[0042] The process of masking spraying is: first spray the exterior color of the car body, then mask the areas that do not need to be sprayed for the second time, and then spray the high gloss black for the first time. The first body color spraying is a conventional spraying process, and the first pass rate and efficiency are consistent with the industry level. The first body color spraying process is as follows: Figure 14 As shown, the first step is injection molding of the white blank, the second step is pre-treatment, the third step is primer spraying, the fourth step is leveling, the fifth step is color paint spraying, the sixth step is leveling, the seventh step is clear varnish spraying, the eighth step is leveling, the ninth step is post-treatment, the tenth step is quality inspection, and the last step is to the masking station, and then enter the masking spraying. The second masking spraying process of high gloss black is as follows Figure 15 As shown, the first step is to paste the color separation tape, the second step is to paste the masking paper, the third step is pre-treatment, the fourth step is flame treatment, the fifth step is high-gloss black spraying, the sixth step is leveling, the seventh step is post-processing, the eighth step is quality inspection, and the last step is entering the qualified product warehouse.

[0043] This process is the most critical step for masking non-sprayed areas. The efficiency and quality of this process directly impact product qualification and output. Therefore, applying the color tape and masking paper to the non-sprayed areas is a crucial step. The technical requirements for the appearance of masking spray coating are as follows: Because the color separation line is the interface between the primary and secondary spray coats, paint flaking is not permitted at this interface, and the paint performance along this edge is not evaluated. The color separation line at the masking spray coating is permitted to have a slight jagged pattern of 10 mm in length, with no more than two spots. When observing the masking spray coating color separation line at a distance of 60 cm from the product, no noticeable waving is allowed. Currently, applying the color separation tape and masking paper is a completely manual process. Improper application of the color separation tape can result in appearance defects such as jagged, wavy, paint mist, and butt joints, seriously impacting qualification and output.

[0044] In the related art, the workpiece to be sprayed is generally placed directly on the workbench and the tape is applied directly. The workpiece to be sprayed is easily displaced, which is prone to errors and affects the adhesive application effect. The workpiece to be sprayed needs to be moved to change the angle of the tape application operation, which is inconvenient for workers. The masking work efficiency is relatively low, with an output rate of only 5 pieces per hour and a pass rate of only about 30%. The output rate and pass rate are low. The embodiment of the present application provides an automotive exterior spraying tool 1 that can facilitate the application of color separation tape and masking paper to the workpiece to be sprayed 2, thereby improving the efficiency of the masking process.

[0045] Reference Figure 1 、 Figure 2 and Figure 3The embodiment of the present application provides an automobile exterior spraying tool 1, which includes a base frame 11, a bracket 12, a connecting assembly 13 and a locking assembly 14, wherein the bracket 12 is rotatably connected to the base frame 11, and the bracket 12 is used to support the workpiece 2 to be sprayed; the connecting assembly 13 is arranged on the bracket 12, and the connecting assembly 13 is used to fix the workpiece 2 to be sprayed on the bracket 12; the locking assembly 14 is used to lock the relative position of the bracket 12 and the base frame 11.

[0046] An embodiment of the present application provides an automobile exterior spraying tool 1. Since a base frame 11 is provided on the tool, the base frame 11 is used to be placed on the ground to support the entire automobile exterior spraying tool 1. Since a bracket 12 is rotatably connected to the base frame 11, the bracket 12 is used to support the workpiece 2 to be sprayed, so that the workpiece 2 to be sprayed can be rotated on the automobile exterior spraying tool 1, and the color separation tape and masking paper can be pasted on the workpiece 2 to be sprayed from multiple angles. Since the automobile exterior spraying tool 1 includes a connecting component 13, the connecting component 13 is used to fix the workpiece 2 to be sprayed on the bracket 12, so that the workpiece 2 to be sprayed can be fixed on the automobile exterior spraying tool 1. Therefore, it is possible to avoid displacement of the workpiece 2 to be sprayed relative to the bracket 12 when the color separation tape and masking paper are pasted on the workpiece 2 to be sprayed, thereby improving the pass rate and output rate of pasting the color separation tape and masking paper on the workpiece 2 to be sprayed. Furthermore, because the automobile exterior painting tool 1 includes a locking assembly 14, the locking assembly 14 is used to lock the relative positions of the bracket 12 and the base 11, so that the bracket 12 can be fixed between the base 11 and stop rotating when the workpiece 2 to be sprayed is rotated to a suitable position. Therefore, it is possible to further avoid the workpiece 2 to be sprayed from being displaced relative to the base 11 when the color separation tape and masking paper are pasted on the workpiece 2 to be sprayed. Compared with the related art that generally places the workpiece 2 to be sprayed directly on the workbench and directly affixes the tape, the workpiece 2 to be sprayed is easy to shift, prone to errors, affecting the pasting effect, and it is necessary to move the workpiece 2 to be sprayed to change the angle of the tape pasting operation, which is inconvenient for workers to work and has a relatively low efficiency in masking work. The embodiment of the present application is rotatably connected to the base frame 11 through the bracket 12. The rotation of the bracket 12 avoids the back and forth clamping of the workpiece to be sprayed to achieve the pasting of color separation tape and masking paper at different angles, and the connecting component 13 is set on the bracket 12 to fix the workpiece 2 to be sprayed on the bracket 12. The locking component 14 is used to lock the relative position of the bracket 12 and the base frame 11, which can enhance the stability of the workpiece to be sprayed 2 installed on the bracket 12, and facilitate the adjustment of the angle of the workpiece to be sprayed 2, and can facilitate the pasting of color separation tape and masking paper on the workpiece to be sprayed 2, further improving the efficiency of the masking link.

[0047] Here, it should be noted that the base frame 11 can be of various shapes, which are not limited here. For example, the base frame 11 can be a three-dimensional frame structure composed of multiple vertical rods and multiple horizontal rods, and can be composed of two frames. In order to place it more stably, the bottom frame can be set to be larger than the upper frame, and the upper frame is connected to the bracket 12.

[0048] In addition, the overall height of the entire vehicle exterior spraying tool can be of various types, and can be set according to the size of the workpiece to be sprayed and the average height of the operator, and there is no restriction here. Among them, the height of the setting of the bracket 12 can also be of various types, and can also be set according to the size of the workpiece 2 to be sprayed and the average height of the operator, and there is no restriction here. For example, the overall height of the vehicle exterior spraying tool can be about 190 cm, and the operating height of the workpiece 2 to be sprayed on the bracket 12 is about 130 cm. In this way, it can be more in line with the ergonomics of the operating user, making the user more comfortable when working, and correspondingly improving the working efficiency and pass rate.

[0049] In addition, the angle at which the bracket 12 supports the side of the workpiece 2 to be sprayed can be various, which are not limited here. For example, it can be parallel to the horizontal plane or perpendicular to the horizontal plane.

[0050] In some embodiments provided in this application, reference is made to Figure 1 、 Figure 2 ,and Figure 3 The bracket 12 has a supporting surface for supporting the workpiece 2 to be sprayed, and the supporting surface is inclined relative to the horizontal plane and has an angle θ.

[0051] In this way, users can more conveniently stick color separation tape and masking paper on the recessed areas on the outer surface of the spray workpiece 2, making the automotive exterior spray tool 1 more ergonomic, more convenient for users to operate, improving user comfort during operation, and improving user work efficiency and product qualification rate.

[0052] It should be noted that the angle of the support surface relative to the horizontal plane can be a variety of angles, which are not limited here. The angle θ of the support surface relative to the horizontal plane can range from 0 degrees < θ ≤ 90 degrees. In some embodiments provided in the present application, the angle θ of the support surface relative to the horizontal plane is 75 degrees. This angle of the support surface relative to the horizontal plane makes it easier to apply color separation tape and masking paper to the recessed areas on the outer surface of the workpiece 2 to be sprayed, making it more user-friendly and further improving the user's comfort during operation. In addition, the angle at which the bracket 12 supports the side of the workpiece 2 to be sprayed can also be set to be adjustable, and the user can adjust the angle according to needs.

[0053] In addition, the support surface is tilted relative to the horizontal plane and has an angle. The bracket 12 can also be tilted relative to the horizontal plane and has an angle. The bracket 12 is rotatably connected to the base 11, and the surfaces connecting the bracket 12 and the base can be parallel to facilitate rotation between the bracket 12 and the base 11.

[0054] In some other embodiments provided in this application, refer to Figure 1 、 Figure 2 and Figure 3 The connection between the base frame 11 and the bracket 12 has a connecting portion 111, and the surface of the connecting portion 111 facing the bracket 12 is parallel to the support surface. In this way, the bracket 12 is connected to the connecting portion 111, the support surface and the connecting portion 111 are parallel, and the surfaces of the bracket 12 and the connecting portion 111 are parallel, which facilitates the rotation of the bracket 12 relative to the base frame 11 and facilitates the locking assembly 14 to fix the bracket 12.

[0055] It should be noted that the connecting part 111 can be arranged on the side of the base frame 11 facing the bracket 12. The connecting part 111 is composed of multiple inclined vertical rods and a connecting plate 1111. For example, two vertical rods are inclined on the base frame 11, one end of the two vertical rods is connected to the upper horizontal rod of the bottom frame, and the other end of the two vertical rods is connected to the upper horizontal rod of the upper frame. The connecting plate 1111 can be arranged at the edge of the two vertical rods close to the upper frame, and the bracket 12 can be connected to the middle of the connecting plate 1111.

[0056] In addition, the position at which the workpiece 2 to be sprayed is fixed on the bracket 12 can be fixed, that is, the target position of the workpiece 2 to be sprayed can be set. When installing the workpiece 2 to be sprayed, the workpiece 2 to be sprayed can be quickly installed to the target position on the bracket 12, realizing fast one-time clamping without having to adjust the position and repeat clamping later.

[0057] In some other embodiments provided in this application, refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The automobile exterior spraying tool 1 includes at least one positioning member 15, which is arranged on the supporting surface. The positioning member 15 is arranged at a position corresponding to the inner protruding structure of the workpiece 2 to be sprayed. The positioning member 15 has a positioning portion 151, and the positioning portion 151 matches the shape of the inner protruding structure of the workpiece 2 to be sprayed. The positioning portion 151 is used to abut against the inner protruding structure of the workpiece 2 to be sprayed to limit the displacement of the workpiece 2 to be sprayed on the bracket 12.

[0058] In this way, the positioning portion 151 limits the position of the workpiece 2 to be sprayed. When installing the workpiece 2 to be sprayed, the workpiece 2 to be sprayed can be quickly installed to the target position on the bracket 12, realizing fast one-time clamping without the need to adjust the position and repeat clamping later.

[0059] It should be noted that the position of the positioning member 15 can be various, and is not limited here. The positioning member 15 is correspondingly set at the position corresponding to the inner protruding structure of the workpiece 2 to be sprayed. Because the workpiece 2 to be sprayed can have multiple inner protruding structures, the position of the inner protruding structure of the workpiece 2 to be sprayed can be various, and the position of the positioning member 15 can be set according to the shape of different positions of the inner protruding structure of the workpiece 2 to be sprayed. The shape of the positioning portion 151 of the positioning member 15 can be various, and is not limited here. The shape of the positioning portion 151 is set according to the shape of the inner protruding structure of the workpiece 2 to be sprayed. The positioning portion 151 abuts against the inner protruding structure of the workpiece 2 to be sprayed to limit the displacement of the workpiece 2 to be sprayed on the bracket 12. The displacement in multiple directions can be limited here, and no limitation is made here. For example, the displacement in the first direction can be limited, the displacement in the second direction can be limited, and the displacement in the third direction can be limited. The first direction can be the direction of the length of the workpiece 2 to be sprayed, that is, the direction of the left and right sides of the workpiece 2 to be sprayed, and it is also the direction of the length of the bracket 12. The second direction can be the direction of the height of the workpiece 2 to be sprayed, that is, it can be the direction of the upper and lower sides of the workpiece 2 to be sprayed, and it is also the direction of the height of the bracket 12. The third direction can be the direction of the thickness of the workpiece 2 to be sprayed, wherein the second direction is perpendicular to the first direction, and the third direction is perpendicular to the first direction and the second direction.

[0060] In addition, since the support surface on the bracket 12 that supports the workpiece 2 to be sprayed is inclined relative to the horizontal plane, the inclined support surface can easily cause the workpiece 2 to be sprayed to slide down, and the positioning member 15 can be configured to support the workpiece 2 to be sprayed to prevent the workpiece 2 to be sprayed from sliding down on the inclined support surface.

[0061] In some other embodiments provided in this application, refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 11 、 Figure 12 ,and Figure 13 The upper surface of the positioning portion 151 is used to abut against the lower surface of the corresponding inner protrusion structure of the workpiece 2 to be sprayed, so as to support the workpiece 2 to be sprayed. In this way, when the support surface of the bracket 12 supporting the workpiece 2 to be sprayed is inclined relative to the horizontal plane, the workpiece 2 to be sprayed on the inclined support surface can be prevented from sliding off, and the workpiece 2 to be sprayed can be supported to prevent displacement of the workpiece 2 to be sprayed in the second direction.

[0062] It should be noted that the material of the positioning member 15 can be a variety of materials, which are not limited here. For example, it can be an aluminum alloy material. In addition, there can be multiple positioning members 15, which are not limited here. For example, a first positioning member and a second positioning member can be respectively provided at both ends of the lower edge of the raised structure on the inner upper part of the workpiece 2 to be sprayed. The first positioning member and the second positioning member are provided with a first positioning portion and a second positioning portion on the surface facing the third direction. The first positioning portion and the second positioning portion are L-shaped abutting protrusions. The L-shaped abutting protrusions on the first positioning member and the second positioning member abut against the lower edge and both side edges of the inner raised structure of the workpiece 2 to be sprayed to limit the upward displacement of the workpiece 2 to be sprayed in the first and second directions. The surfaces of the first positioning member and the second positioning member facing the third direction that are not provided with the first positioning portion and the second positioning portion abut against the raised structure on the inner upper part of the workpiece 2 to be sprayed to limit the upward displacement of the workpiece 2 to be sprayed in the third direction. Secondly, a third positioning member and a fourth positioning member can be respectively provided at both ends of the lower edge of the raised structure on the inner lower part of the workpiece 2 to be sprayed, and the third positioning member and the fourth positioning member are vertical long strips, and the third positioning member and the fourth positioning member are provided with a third positioning portion and a fourth positioning portion on the surface facing the third direction, and the third positioning portion and the fourth positioning portion are raised structures extending along the third direction, and the right side surface of the third positioning portion and the left side surface of the fourth positioning portion abut against the two side edges of the raised structure on the inner lower part of the workpiece 2 to be sprayed to limit the upward displacement of the workpiece 2 to be sprayed in the first direction, that is, to limit the left and right movement of the workpiece 2 to be sprayed. Finally, a fifth positioning member and a sixth positioning member can be respectively provided at both ends of the lower edge of the inner convex structure of the workpiece 2 to be sprayed. The fifth positioning member and the sixth positioning member are horizontally long strips. The fifth positioning member and the sixth positioning member are provided with a fifth positioning portion and a sixth positioning portion on the surface facing the third direction. The fifth positioning portion and the sixth positioning portion are convex structures extending along the third direction. The side surfaces of the ends of the fifth positioning portion and the sixth positioning portion abut against the surface of the inner convex structure of the workpiece 2 to be sprayed to limit the upward displacement of the workpiece 2 to be sprayed in the third direction. The distance between the workpiece 2 to be sprayed and the bracket 12 can also be controlled to avoid excessive squeezing of the connecting part by the workpiece 2 to be sprayed.

[0063] In addition, refer to Figure 1 、 Figure 2 and Figure 3The locking assembly 14 can include various types. For example, it can be a latch. Coaxial fixing holes are respectively provided on the bracket 12 and the base frame 11. When the bracket 12 is rotated to the target position relative to the base frame 11, the fixing holes on the bracket 12 and the base frame 11 are coaxial. The latch is inserted into the two fixing holes to fix the bracket 12 and the base frame 11. Multiple groups of fixing holes can be provided on the bracket 12 and the base frame 11. At different positions on the bracket 12 and the base frame 11, the bracket 12 can be fixed at different angles. Alternatively, the locking assembly 14 can be a clamping member. When the bracket 12 is rotated to the target position relative to the base frame 11, the clamping member can clamp the bracket 12 and the base frame 11 together.

[0064] In some other embodiments provided in this application, refer to Figure 1 、 Figure 2 and Figure 3 The bracket 12 includes a base 121 and a support frame 122. The support frame 122 is fixed on the base 121. The support frame 122 is used to support the workpiece 2 to be sprayed. The base 121 is rotatably connected to the base 11. The locking assembly 14 includes an adsorption member 141 arranged on the base 11; when the bracket 12 rotates to the target position relative to the base 11, the adsorption member 141 is adsorbed with the base 121 to lock the relative position of the bracket 12 and the base 11.

[0065] In this way, the bracket 12 can be rotated relative to the base 11 to an angle that is convenient for operating the workpiece 2 to be sprayed. The adsorption part 141 adsorbs the part and the base 121, fixes the base 121, and fixes the workpiece 2 to be sprayed on the support frame 122, so that it is fixed and no longer rotates, and hovering at any rotation angle is achieved, which is convenient for users to operate the workpiece 2 to be sprayed.

[0066] It should be noted that the base 121 can be of various shapes, for example, without limitation, and can be a plate structure, a square plate, or a circular plate. Furthermore, the base 121 can be made of various adsorbable materials, for example, without limitation, such as steel.

[0067] In addition, the fixed connection or movably connection between the adsorption member 141 and the base 11 is not limited here. For example, the adsorption member 141 can be movably connected to the base 11, one end of the adsorption member 141 is movably connected to the base 11, and the other end can be rotated. When the bracket 12 is rotated to the target position relative to the base 11, the other end of the adsorption member 141 is adsorbed on the base 121. When the workpiece 2 to be sprayed needs to be rotated, the other end of the adsorption member 141 can be rotated away from the base 121 to release the adsorption of the other end of the adsorption member 141 from the base 121.

[0068] In some other embodiments provided in this application, refer to Figure 1、 Figure 2 and Figure 3 The adsorption member 141 is an electromagnet. The locking assembly 14 also includes a wire and a locking switch 142. The electromagnet is connected to a power source via the wire and the locking switch 142. The locking switch 142 is used to control the on and off of the electromagnet. In this way, the user can use the locking switch 142 to control the state of the bracket 12, that is, the fixed state or the rotatable state.

[0069] It should be noted that when the locking switch 142 controls the electromagnet to be powered on, the electromagnet is adsorbed on the base 121. When the locking switch 142 controls the electromagnet to be powered off, the electromagnet is attached to the base 121, and the bracket 12 can be operated to drive the workpiece 2 to be sprayed to rotate.

[0070] In addition, the adsorption member 141 can be fixed on the connecting portion 111 on the base, and can be fixed at any position of the connecting portion 111 except the connection with the base 121. There is no limitation here. For example, the adsorption member 141 can be set at a position close to the edge of the base 121, and can also be set at a position at the lower edge of the base 121.

[0071] In addition, the locking switch 142 can be set at various locations, which are not limited here. For example, it can be set on the base frame 11 or on the bracket 12. The locking switch 142 can be of various types, which are not limited here. For example, it can be a manual switch or a foot switch.

[0072] In some other embodiments provided in this application, refer to Figure 1 、 Figure 2 and Figure 4 The locking switch 142 is a foot switch, which is arranged at the lower side of the bracket 12. In this way, the user can directly operate the foot switch with his feet when operating the bracket 12 with both hands, which is convenient for the user to operate with both hands and feet, thereby improving the efficiency of the operation.

[0073] In addition, the connection assembly 13 may include a variety of connection methods, which are not limited here. For example, the connection assembly 13 may include a clamping member, and multiple clamping members may be provided, each disposed at the edge of the workpiece 2 to be sprayed, to clamp and fix the workpiece 2 to be sprayed. The connection assembly 13 may also include a suction cup 131, which adsorbs and fixes the workpiece 2 to be sprayed.

[0074] In some other embodiments provided in this application, refer to Figure 4 、 Figure 8 、 Figure 9 and Figure 10The connecting component 13 includes multiple suction cups 131, a vacuum pipe 132 and a vacuum generator 134. The multiple suction cups 131 are connected to the vacuum generator 134 through the vacuum pipe 132. The vacuum generator 134 is used to extract the air in the multiple suction cups 131 through the vacuum pipe 132, so that the multiple suction cups 131 adsorb and fix the workpiece 2 to be sprayed; the connecting component 13 also includes a wire and a connecting switch 135. The vacuum generator 134 is connected to the power supply through the wire and the connecting switch 135. The connecting switch 135 is used to control the on and off of the vacuum generator 134.

[0075] In this way, the vacuum pipe 132 connects each suction cup 131, providing negative pressure. The suction cup 131 absorbs the inner surface of the workpiece 2 to be sprayed to fix the workpiece 2 to be sprayed. This prevents the outer surface of the workpiece 2 from being worn or scratched, and avoids pressure on the surface of the workpiece 2 to be sprayed, which may cause deformation of the workpiece 2 to be sprayed. In addition, the connection switch 135 can control the power supply of the vacuum generator 134 on and off. In other words, it can be used to control the on and off of the vacuum pipe 132, controlling the suction cup 131 to absorb or desorb the workpiece 2 to be sprayed, so that the workpiece 2 to be sprayed can be quickly installed on or released from the bracket 12.

[0076] It should be noted that when the connection switch 135 controls the power supply of the vacuum generator 134, the vacuum generator 134 extracts the air in the suction cup 131 through the vacuum pipe 132, so that the suction cup 131 maintains a vacuum state, and the suction cup 131 adsorbs the inner surface of the workpiece 2 to be sprayed. When the connection switch 135 controls the power supply of the vacuum generator 134 to be disconnected, the vacuum generator 134 stops working, the suction cup 131 and the workpiece 2 to be sprayed are desorbed, and the workpiece 2 to be sprayed can be removed from the bracket 12.

[0077] Secondly, the vacuum pipe 132 can be made of a variety of materials, which are not limited here. For example, it can be a nylon tube.

[0078] Furthermore, multiple suction cups 131 are fixed to the bracket 12 and positioned at the outer edge of the workpiece 2 to be sprayed, spaced circumferentially and proximately to the outer edge of the workpiece 2 to be sprayed. Furthermore, the positions of the multiple suction cups 131 can be staggered relative to the mounting member and relative to the raised portion of the inner surface of the workpiece 2 to be sprayed. Furthermore, the number of suction cups 131 can be set as needed, and the number of suction cups 131 can be adapted to the size of the workpiece 2 to be sprayed, without limitation. For example, eight suction cups 131 can be arranged in a "convex" shape on the bracket 12. Furthermore, the sizes of the suction cups 131 can be varied, without limitation, and can be selected to suit the size and weight of the workpiece 2 to be sprayed. For example, the diameter of the suction cups 131 can be 50 mm. Furthermore, the materials of the suction cups 131 can be varied, without limitation. For example, the suction portion 1311 of the suction cup 131 can be made of silicone to prevent abrasion or scratching of the surface of the workpiece 2 to be sprayed.

[0079] In some other embodiments provided by the present application, the suction cup 131 is connected to the bracket 12 through a suction cup mounting bracket 1312, and the suction cup 131 and the suction cup mounting bracket 1312 are connected by bolts 1313 and elastic members 1314, the bolts 1313 are used to adjust the height of the suction cup 131, and the elastic members 1314 are used to buffer the space between the suction cup 131 and the suction cup mounting bracket 1312, wherein the elastic members 1314 can be of various types and are not limited here. For example, the elastic member 1314 can be a compression spring; the suction cup mounting bracket 1312 is L-shaped, and the horizontal section is used to connect with the suction cup 131, and a mounting groove 13121 is provided on the vertical end, and the height of the suction cup 131 can be adjusted as needed; pipe connection ports 1315 are symmetrically provided on both sides of the bottom of the suction cup 131 for connecting the vacuum pipe 132. In this way, when the workpiece 2 to be sprayed is mounted, the workpiece 2 to be sprayed presses against the suction cup 131, and the elastic member 1314 can prevent the suction cup 131 from colliding with the suction cup mounting bracket 1312, thereby preventing the workpiece 2 to be sprayed from being knocked off. In addition, the first positioning member, the second positioning member, the fifth positioning member, and the sixth positioning member can also limit and control the distance between the workpiece 2 to be sprayed and the bracket 12, that is, they can prevent the elastic member 1314 of the suction cup 131 from being overly compressed, thereby preventing the workpiece 2 to be sprayed from excessively squeezing the suction cup 131.

[0080] In addition, refer to Figure 1 、 Figure 3 and Figure 8 The base frame 11 and the base 121 can be rotatably connected, and can be connected in various ways, which are not limited here. For example, the connecting shaft 16 can be used to connect to the base frame through an axis.

[0081] In some other embodiments provided in this application, refer to Figure 1 、 Figure 3and Figure 8 The base frame and the base 121 rotate via the connecting shaft 16. The center of the connecting shaft 16 is provided with a receiving hole 161. The vacuum pipe 132 passes through the receiving hole 161. The vacuum generator 134 is provided on the base frame 11. One end of the vacuum pipe 132 is connected to the multiple suction cups 131, and the other end of the vacuum pipe 132 is connected to the vacuum generator 134. In this way, the multiple suction cups 131 and the vacuum pipe 132 can rotate with the bracket 12, and the bracket 12 can rotate 360 degrees without restriction.

[0082] It should be noted that the connecting shaft 16 can be of various types and is not limited here. For example, the connecting shaft 16 can be a ball bearing, the inner ring of the ball bearing is connected to the middle position of the connecting plate 1111, and the outer ring of the ball bearing is connected to the middle position of the base 121.

[0083] In addition, the vacuum generator 134 is arranged on the storage plate on the bottom frame of the base 11, a first through hole 11111 is provided in the middle of the connecting plate 1111, a second through hole 1211 is provided in the middle of the base 121, the first through hole 11111 and the second through hole 1211 as well as the accommodating hole 161 in the middle of the connecting shaft 16 are coaxially arranged, and the vacuum pipe 132 passes through the second through hole 1211, the accommodating hole 161 and the first through hole 11111 in sequence, and extends downward to connect with the vacuum generator 134.

[0084] Secondly, the power control box 17 is also set on the storage plate on the bottom frame of the base 11. The power control box 17 is used to provide power and electricity for various controllers. The power control box 17 is connected to the vacuum generator 134 and the adsorption part 141. The locking switch 142 and the connection switch 135 are also connected to the power control box 17 to control the power supply of the vacuum generator 134 and the adsorption part 141 to control the fixation of the workpiece 2 to be sprayed and the rotation of the bracket 12.

[0085] In some other embodiments provided in this application, refer to Figure 1 、 Figure 8 and Figure 9 The vacuum pipe 132 includes a fixed section 1322 and a connecting section 1321. The fixed section 1322 is connected to the vacuum generator 134. The connecting section 1321 connects multiple suction cups 131 in series. The fixed section 1322 is rotatably connected to the connecting section 1321 through a rotating connector 133, so that the connecting section 1321 can rotate with the bracket 12, and the fixed section 1322 will not rotate, thereby solving the problem of the vacuum pipe 132 being entangled during the rotation of the suction cup 131.

[0086] It should be noted that the rotating connector 133 is fixed to the connecting plate 1111. Both ends of the rotating connector 133 have connection ports. The fixed section 1322 and the connecting section 1321 are respectively inserted into the connection ports for connection. The connection ports are provided with fasteners that can securely connect the fixed section 1322 and the connecting section 1321 within the connection ports to prevent the fixed section 1322 and the connecting section 1321 from loosening and falling out. The rotating connector 133 has a rotating pipe joint 1331 inside. The fixed section 1322 and the connecting section 1321 are respectively connected to the rotating pipe joint 1331, so that air can flow from the connecting section 1321 through the rotating pipe joint 1331 into the fixed section 1322. When the connecting section 1321 rotates, one end of the rotating pipe joint 1331 rotates accordingly. At this time, the other end of the rotating pipe joint 1331 is fixed, so that the fixed section 1322 can be fixed and does not rotate.

[0087] In addition, the connection switch 135 can be set at a variety of locations, which are not limited here. For example, it can be set on the base frame 11 or on the bracket 12.

In this way, when the workpiece 2 to be sprayed is removed from the bracket 12, the user can hold the workpiece 2 to be sprayed and step on the foot switch with his foot to stop the vacuum generator 134, so that the suction cup 131 and the workpiece 2 to be sprayed are desorbed, and the workpiece 2 to be sprayed can be quickly removed from the bracket 12.

[0089] In addition, the rotation of the bracket 12 can be manual rotation by the user or automatic rotation, which is not limited here. For example, a rotation drive component can be provided to drive the bracket 12 to rotate.

[0090] In some other embodiments provided in this application, refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 11 The support frame 122 is a planar frame composed of multiple horizontal bars and multiple vertical bars. The area within the planar frame includes an installation area and an operation area. The installation area is used to install the workpiece 2 to be sprayed.

The light tube is connected to a power supply via a wire, and the power supply provides electricity to the light tube. It should be noted that the illumination of the light box 193 can be various, without limitation here. For example, the illumination of the light box 193 is ≥1500 lux, and can achieve uniform illumination and natural pure fluorescent lighting.

[0094] In some other embodiments provided in this application, refer to Figure 1 and Figure 2 The end of the lamp bracket 12 is also provided with a shelf 192, which extends along the first direction and is provided with a hanging rod for hanging color separation tape and other working tools. This can facilitate the user to improve work efficiency when applying color separation tape to the outer surface of the workpiece 2 to be sprayed.
