Description

Technical Field

[0002] Electrophoretic coating is a process that uses an external electric field to cause pigments and resin particles suspended in an electrophoretic solution to migrate directionally and deposit onto the surface of the workpiece to be coated, using one of the electrodes. Due to its high coating efficiency, electrophoretic coating is widely used in vehicle coating.

[0003] Once vehicles enter production, the demand for vehicle spare parts increases dramatically, including the production demand for front and rear covers, which are key components of the vehicle body. By immersing the front and rear covers in an electrochemical bath, a protective paint layer is deposited on their surfaces.

[0055] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0056] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0057] During its research, the applicant discovered that the demand for vehicle spare parts increases dramatically after vehicles go into production, including the front and rear covers, which are major components of the vehicle body. Electrophoretic coating is required during the production of these spare parts. After electrophoretic coating, a protective paint layer forms on the surface of the front and rear covers, improving their rust and corrosion resistance. Before entering the coating system, the front and rear covers are typically placed on an electrophoretic coating fixture to ensure optimal coating performance. Existing electrophoretic coating fixtures are of two types: one is a dedicated fixture for a single vehicle model; the other is a basket-type fixture shared by multiple vehicle models.

[0058] However, using a dedicated electrophoretic coating fixture for a single vehicle model only allows for that specific model's application. Different fixtures need to be designed for different models, increasing the production cost of front and rear hood parts. Furthermore, the need to store these different fixtures consumes excessive workshop space. Additionally, the electrophoretic coating process for different vehicle models requires changing to dedicated fixtures, which reduces production line efficiency. While basket-type coating fixtures can be used for multiple models, they are not perfectly compatible with the parts for different models, leading to defective parts.

[0059] In view of this, embodiments of this application provide a coating equipment and a coating system. The coating equipment includes an operating platform, a workpiece mounting assembly, and a skid connection assembly. The workpiece mounting assembly includes a workpiece mounting frame, a plurality of first workpiece mounting parts, and a plurality of second workpiece mounting parts. By arranging the plurality of first workpiece mounting parts and the plurality of second workpiece mounting parts sequentially at intervals along the extension direction of the workpiece mounting frame and setting them at different positions along the height of the workpiece mounting frame, the space of the workpiece mounting frame is rationally utilized, space utilization is maximized, coating of various workpieces is realized, and coating work efficiency is improved.

[0060] In addition, both the first workpiece mounting component and the second workpiece mounting component include a mounting connection part and a mounting adjustment part. The mounting connection part is connected to the workpiece mounting frame, which improves the connection strength between the first workpiece mounting component, the second workpiece mounting component and the workpiece mounting frame. The connection position of the mounting adjustment part on the mounting connection part is adjustable. In this way, the coating equipment can install workpieces of different sizes and improve the versatility of the coating equipment.

[0061] By setting up a skid connection assembly, a forklift can move the painting equipment equipped with the skid connection assembly to a designated position. By locking the skid connection assembly to the track of the painting system, the stability of the painting equipment on the track of the painting system is improved, thereby increasing the working efficiency of the painting system.

[0062] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0063] Firstly, referring to Figures 1 to 3 As shown, this application provides a coating equipment for coating multiple workpieces. The coating equipment includes an operating platform 300, a workpiece mounting assembly 100, and a skid connecting assembly 200. The workpiece mounting assembly 100 is disposed on the top of the operating platform 300, and the skid connecting assembly 200 is disposed on the bottom of the operating platform 300.

[0064] The workpiece mounting assembly 100 includes a workpiece mounting frame 140, a plurality of first workpiece mounting parts 110 and a plurality of second workpiece mounting parts 120; the plurality of first workpiece mounting parts 110 and the plurality of second workpiece mounting parts 120 are arranged sequentially at intervals along the extension direction of the workpiece mounting frame 140 and are respectively located at different positions along the height direction of the workpiece mounting frame 140.

[0065] Both the first workpiece mounting component 110 and the second workpiece mounting component 120 include a mounting connection part and a mounting adjustment part. The mounting connection part extends along the extension direction of the workpiece mounting frame 140 and is connected to the workpiece mounting frame 140. The mounting adjustment part is movably connected to the mounting connection part, and the connection position of the mounting adjustment part on the mounting connection part is adjustable.

[0066] For example, refer to Figure 1 As shown, the workpiece mounting frame 140 is disposed on the top of the operating platform 300, and the workpiece mounting frame 140 extends along... Figure 1 Extending in the X direction as shown, along the extension direction of the workpiece mounting frame 140, a plurality of first workpiece mounting parts 110 are sequentially arranged on the top of the workpiece mounting frame 140, and a plurality of second workpiece mounting parts 120 are sequentially arranged on the bottom of the workpiece mounting frame 140. By setting the first workpiece mounting parts 110 and the second workpiece mounting parts 120, the space of each part of the workpiece mounting frame 140 is rationally utilized, and the coating equipment can coat multiple workpieces and different workpieces at the same time, thereby improving the efficiency of workpiece coating.

[0067] In some embodiments, refer to Figure 3 As shown, when there are three first workpiece mounting parts 110, the three first workpiece mounting parts 110 are installed sequentially at the top left, middle and right ends of the workpiece mounting frame 140; when there are two second workpiece mounting parts 120, the second workpiece mounting parts 120 are installed at the bottom left and right ends of the workpiece mounting frame 140. In this way, the space of the workpiece mounting frame 140 can be used reasonably, the space utilization can be maximized, and multiple workpieces can be painted simultaneously.

[0068] It is understood that the number of the first workpiece mounting component 110 and the second workpiece mounting component 120 is reasonably set according to the dimensions of the workpiece mounting frame 140 and the dimensions of the workpiece, with the principle of meeting coating requirements and maximizing space utilization. This application does not limit the number of the first workpiece mounting component 110 and the second workpiece mounting component 120.

[0069] For example, refer to Figure 3As shown, by configuring the structure of the first workpiece mounting part 110 and the second workpiece mounting part 120 as a mounting connection part and a mounting adjustment part, and connecting the mounting connection part to the workpiece mounting frame 140, the connection strength between the first workpiece mounting part 110, the second workpiece mounting part 120 and the workpiece mounting frame 140 is improved. The mounting adjustment part is movably connected to the mounting connection part, and the mounting adjustment part can be adjusted at the actual connection position of the mounting connection part. In this way, the installation of workpieces of the same type but different sizes can be realized, realizing the versatility of multi-size workpieces in the coating equipment. At the same time, by setting the mounting connection part, when the workpiece is installed on the first workpiece mounting part 110 or the second workpiece mounting part 120, the mounting connection part can provide support, improving the support stability of the first workpiece mounting part 110 and the second workpiece mounting part 120 after the workpiece is installed.

[0070] For example, after the workpiece is mounted on the workpiece mounting assembly 100 on the operating platform 300, the forklift can move the entire operating platform 300 via the skid connection assembly 200 at the bottom of the operating platform 300, and the painting equipment can be moved to a designated position at any time.

[0071] For example, the operating platform 300 and the workpiece mounting frame 140 can be made of channel steel, which can reduce the weight of the coating equipment while ensuring its strength. An operating platform grating can also be installed on the operating platform 300 to improve its load-bearing capacity.

[0072] For example, the tailgate can be installed at the first workpiece mounting part 110, and the hood can be installed at the second workpiece mounting part 120, so as to achieve simultaneous painting of the tailgate and the hood. In the following description of this application, the workpiece at the first workpiece mounting part 110 is the tailgate, and the workpiece at the second workpiece mounting part 120 is the hood.

[0073] In one feasible implementation, the first workpiece mounting component 110 includes a first mounting connection portion 111 and a first mounting adjustment portion 112. The first mounting connection portion 111 is mounted on the top end of the workpiece mounting frame 140. The first mounting adjustment portion 112 includes a first connecting plate 112a and a first locking plate 112b. The first locking plate 112b is connected to the first connecting plate 112a and has a first locking area. At least a portion of the first mounting connection portion 111 passes through the first locking area.

[0074] When the first locking plate 112b is in the unlocked state, the first mounting adjustment part 112 reciprocates along the extension direction of the first mounting connection part 111. When the first locking plate 112b is in the locked state, the first mounting adjustment part 112 and the first mounting connection part 111 are fixed relative to each other.

[0075] For example, refer to Figure 3 and Figure 4 As shown, when the first workpiece mounting member 110 is used to install the tailgate of a vehicle, the first workpiece mounting member 110 includes a first mounting connection portion 111 connected to the workpiece mounting frame 140 and a first mounting adjustment portion 112 for installing the tailgate. The first mounting connection portion 111 is connected to the top of the workpiece mounting frame 140 to securely connect the tailgate to the workpiece mounting frame 140 via the first workpiece mounting member 110. To enable the first workpiece mounting member 110 to match tailgates of different vehicle models, a first locking plate 112b is provided. The two ends of the first mounting connection portion 111 pass through a first locking area formed by the first locking plate 112b, allowing the first mounting adjustment portion 112 to move along the first mounting connection portion 111. The first mounting adjustment portion 112 can be adjusted in position to match different tailgates.

[0076] In some embodiments, refer to Figure 3 As shown, the extension direction of the first mounting connection portion 111 is along the X direction. When the first locking plate 112b is in the locked state, for example, when the first locking plate 112b is disposed in the middle of the first mounting connection portion 111, the first locking area formed by the first locking plate 112b locks the first mounting connection portion 111, and thus the first mounting adjustment portion 112 cannot move along the first mounting connection portion 111. In this way, by fixing the first mounting adjustment portion 112 and the first mounting connection portion 111, the back door installed on the first mounting adjustment portion 112 is fixed.

[0077] In other embodiments, reference is made to Figure 3 As shown, the extension direction of the first mounting connection 111 is along the X direction. When the first locking plate 112b is in the unlocked state, for example, when the first locking plate 112b is located in the middle of the first mounting connection 111, there is a space for movement between the first locking area formed by the first locking plate 112b and the first mounting connection 111. The first mounting adjustment part 112 can move from the middle of the first mounting connection 111 to either end of the first mounting connection 111. In this way, by providing the first mounting adjustment part 112 that can move along the first mounting connection 111, the position of the first mounting adjustment part 112 can be adjusted to adapt to the installation of different back doors, which is beneficial to improving the versatility of the first workpiece mounting part 110, and thus improving the versatility of the coating equipment.

[0078] In one feasible implementation, the first mounting connection 111 includes a first connecting rod 111a and a plurality of first connecting ears 111b. The first connecting rod 111a is connected to the workpiece mounting frame 140 through the first connecting ears 111b. At least one of the plurality of first connecting ears 111b is connected to the middle section of the first connecting rod 111a, and at least two of the plurality of first connecting ears 111b are respectively connected to both ends of the first connecting rod 111a in the extending direction.

[0079] The first connecting plate 112a includes a first fixed section and a first adjusting section that are connected to each other; the first fixed section is provided with a first fixed hole, and the first adjusting section is provided with a first adjusting hole, which extends along a first direction.

[0080] The first locking plate 112b includes a first locking connecting section and at least two first locking sections. The same end of the at least two first locking sections is connected to the connection between the first fixing section and the first adjusting section through the first locking connecting section. The at least two first locking sections are arranged opposite to each other and together form a first locking area. The ends of the at least two first locking sections opposite to the first locking connecting section are provided with fastening holes for fasteners to pass through.

[0081] For example, refer to Figure 4 and Figure 5 As shown, when the first mounting connection part 111 and the workpiece mounting frame 140 are connected, the first connecting rod 111a is passed through the first connecting hole of the first connecting ear 111b, and the first connecting ear 111b is connected to the workpiece mounting frame 140, ensuring the connection strength between the workpiece mounting frame 140 and the first mounting connection part 111. When the first mounting adjustment part 112 and the first mounting connection part 111 are connected, the first mounting adjustment part 112 is connected to the first connecting rod 111a. The first connecting hole is located at the end of the first connecting ear 111b away from the workpiece mounting frame 140. By setting the first connecting ear 111b, the first connecting hole is located at the end of the first connecting ear 111b away from the workpiece mounting frame 140, leaving installation space for the first mounting adjustment part 112.

[0082] For example, there can be three first connecting ears 111b. The two ends of the first connecting rod 111a are respectively connected to two first connecting ears 111b, and a first connecting ear 111b is provided in the middle section of the first connecting rod 111a. By setting the first connecting ears 111b at both ends and the middle section of the first connecting rod 111a, multiple first connecting ears 111b are connected to the workpiece mounting frame 140. This can ensure the connection strength between the first mounting connection part 111 and the workpiece mounting frame 140, improve the load-bearing capacity of the first workpiece mounting part 110 on the back door, and help the back door to be stably installed on the first workpiece mounting part 110.

[0083] For example, the first connecting lug 111b can be connected to the workpiece mounting frame 140 by welding.

[0084] It is understandable that after providing first connecting ears 111b at both ends of the first connecting rod 111a, multiple first connecting ears 111b can be provided in the middle section of the first connecting rod 111a to ensure the connection strength between the first mounting connection part 111 and the workpiece mounting frame 140. The number of first connecting ears 111b is related to the length of the first connecting rod 111a, the connection strength between the first connecting ears 111b and the workpiece mounting frame 140, and the load-bearing capacity provided by the first mounting connection part 111 to the back door. This application does not limit the number of first connecting ears 111b.

[0085] For example, refer to Figure 5 As shown, the first installation adjustment part 112 includes a first connecting plate 112a connected to the back door and a first locking plate 112b connected to the first installation connection part 111. By setting the first locking plate 112b into two first locking sections and one first locking connecting section, the two first locking sections are arranged opposite each other to form a first locking area. The first locking area can move along the first connecting rod 111a, realizing the real-time adjustment of the position of the first locking section on the first connecting rod 111a according to the different back doors. The first locking connecting section is used to connect with the first connecting plate 112a, leaving operating space for the installation of the back door.

[0086] For example, refer to Figure 3 As shown, the first locking plate 112b can not only be along the first mounting connection portion 111 along... Figure 3 As shown, the first locking plate 112b can move in the X direction and can also rotate along the first mounting connection 111. When rotating, the first locking plate 112b rotates from the Y direction to the Z direction. When the first mounting adjustment part 112 is set to the locked state, the two first locking sections are moved to the required position on the first connecting rod 111a, and the two first locking sections are rotated to adapt to the angle of the back door. By passing the fasteners through the fastening holes at the ends of the two first locking sections, the locking state of the first locking plate 112b is achieved.

[0087] For example, the fastener can be a long bolt, and the fastening hole can be a bolt locking hole.

[0088] For example, by detachably connecting the first locking section to the first mounting connection 111 via fasteners, the stability of repeated installation and disassembly of various parts of the painting equipment when matching different back doors is solved. This also facilitates subsequent maintenance and reduces maintenance costs.

[0089] In one feasible implementation, the second workpiece mounting component 120 includes a second mounting connection portion 121 and a second mounting adjustment portion 122. The second mounting connection portion 121 is mounted on the bottom end of the workpiece mounting frame 140. The second mounting adjustment portion 122 includes a second connecting plate 122a and a second locking plate 122b. The second locking plate 122b is connected to the second connecting plate 122a and has a second locking area. At least a portion of the second mounting connection portion 121 passes through the second locking area.

[0090] When the second locking plate 122b is in the unlocked state, the second mounting adjustment part 122 reciprocates along the extension direction of the second mounting connection part 121. When the second locking plate 122b is in the locked state, the second mounting adjustment part 122 and the second mounting connection part 121 are fixed relative to each other.

[0091] For example, refer to Figure 3 and Figure 6 As shown, when the second workpiece mounting member 120 is used to mount a vehicle's hood, the second workpiece mounting member 120 includes a second mounting connection portion 121 connected to the workpiece mounting frame 140 and a second mounting adjustment portion 122 for mounting the hood. The second mounting connection portion 121 is connected to the top of the workpiece mounting frame 140 to securely connect the hood to the workpiece mounting frame 140 via the second workpiece mounting member 120. To allow the second workpiece mounting member 120 to match hoods of different vehicle models, a second locking plate 122b is provided. The two ends of the second mounting connection portion 121 pass through a second locking area formed by the second locking plate 122b, allowing the second mounting adjustment portion 122 to move along the second mounting connection portion 121. The second mounting adjustment portion 122 can be adjusted in position to match different hoods.

[0092] In some embodiments, refer to Figure 3 As shown, the extension direction of the second mounting connection 121 is along the X direction. When the second locking plate 122b is in the locked state, for example, when the second locking plate 122b is provided in the middle of the second mounting connection 121, the second locking area formed by the second locking plate 122b locks the second mounting connection 121, and thus the second mounting adjustment part 122 cannot move along the second mounting connection 121. In this way, by fixing the second mounting adjustment part 122 and the second mounting connection 121, the position of the hood mounted on the second mounting adjustment part 122 is fixed.

[0093] In other embodiments, reference is made to Figure 3As shown, the extension direction of the second mounting connection 121 is along the X direction. When the second locking plate 122b is in the unlocked state, for example, when the second locking plate 122b is located in the middle of the second mounting connection 121, there is a space for movement between the second locking area formed by the second locking plate 122b and the second mounting connection 121. The second mounting adjustment part 122 can move from the middle of the second mounting connection 121 to either end of the second mounting connection 121. In this way, by providing a second mounting adjustment part 122 that can move along the second mounting connection 121, the position of the second mounting adjustment part 122 can be adjusted to adapt to the installation of different engine hoods, which is beneficial to improving the versatility of the second workpiece mounting part 120, and thus improving the versatility of the painting equipment.

[0094] In one feasible implementation, the second mounting connection 121 includes a second connecting rod 121a and a plurality of second connecting ears 121b. The second connecting rod 121a is connected to the workpiece mounting frame 140 through the second connecting ears 121b. At least one of the plurality of second connecting ears 121b is connected to the middle section of the second connecting rod 121a, and at least two of the plurality of second connecting ears 121b are respectively connected to both ends of the second connecting rod 121a in the extending direction.

[0095] The second connecting plate 122a includes a second fixed section and a second adjusting section that are connected to each other; the second fixed section is provided with a second fixed hole, and the second adjusting section is provided with a second adjusting hole, which extends along a second direction.

[0096] The second locking plate 122b includes a second locking connecting section and at least two second locking sections. The same end of the at least two second locking sections is connected to the connection between the second fixing section and the second adjusting section through the second locking connecting section. The at least two second locking sections are arranged opposite to each other and together form a second locking area. The ends of the at least two second locking sections opposite to the second locking connecting section are provided with fastening holes for fasteners to pass through.

[0097] For example, refer to Figure 3 and Figure 6As shown, when the second mounting connection part 121 and the workpiece mounting frame 140 are connected, the second connecting rod 121a is passed through the second connecting hole of the second connecting ear 121b, and the second connecting ear 121b is connected to the workpiece mounting frame 140, ensuring the connection strength between the workpiece mounting frame 140 and the second mounting connection part 121; when the second mounting adjustment part 122 and the second mounting connection part 121 are connected, the second mounting adjustment part 122 is connected to the second connecting rod 121a, wherein the second connecting hole is provided at the end of the second connecting ear 121b away from the workpiece mounting frame 140. By providing the second connecting ear 121b and the second connecting hole being provided at the end of the second connecting ear 121b away from the workpiece mounting frame 140, installation space is provided for the second mounting adjustment part 122.

[0098] For example, after the second mounting adjustment part 122 is fixed to the second mounting connection part 121, the part of the second connecting rod 121a without the second connecting ear 121b is fixed to the locking ring of the hood by wire, so as to further improve the stability of the hood mounted on the second workpiece mounting part 120.

[0099] For example, refer to Figure 6 As shown, there can be four second connecting ears 121b. The two ends of the second connecting rod 121a are respectively connected to two second connecting ears 121b. The middle section of the second connecting rod 121a is provided with two connecting ears. By setting the second connecting ears 121b at the two ends and the middle section of the second connecting rod 121a, multiple second connecting ears 121b are connected to the workpiece mounting frame 140. This can ensure the connection strength between the second mounting connection part 121 and the workpiece mounting frame 140, improve the load-bearing capacity of the second workpiece mounting part 120 on the hood, and help the hood to be stably installed on the second workpiece mounting part 120.

[0100] For example, the second connecting lug 121b can be connected to the workpiece mounting frame 140 by welding.

[0101] It is understood that after providing second connecting ears 121b at both ends of the second connecting rod 121a, multiple second connecting ears 121b can be provided in the middle section of the second connecting rod 121a to ensure the connection strength between the second mounting connection part 121 and the workpiece mounting frame 140. The number of second connecting ears 121b is related to the length of the second connecting rod 121a, the connection strength between the second connecting ears 121b and the workpiece mounting frame 140, and the load-bearing capacity provided by the second mounting connection part 121 to the hood. This application does not limit the number of second connecting ears 121b.

[0102] For example, refer to Figure 7As shown, the second mounting adjustment part 122 includes a second connecting plate 122a connected to the hood and a second locking plate 122b connected to the second mounting connection part 121. By setting the second locking plate 122b into two second locking sections and one second locking connecting section, the two second locking sections are arranged opposite each other to form a second locking area. The second locking area can move along the second connecting rod 121a, which realizes the real-time adjustment of the position of the second locking section on the second connecting rod 121a according to the size of the hood. The second locking connecting section is used to connect with the second connecting plate 122a, leaving operating space for the installation of the hood.

[0103] For example, refer to Figure 3 As shown, the second locking plate 122b can not only be along the second mounting connection portion 121 along... Figure 3 As shown, the second locking plate 122b can move in the X direction and can also rotate along the second mounting connection 121. The second locking plate 122b rotates from the Y direction to the Z direction. When the second mounting adjustment part 122 is set to the locked state, the two second locking sections are moved to the required position on the second connecting rod 121a, and the two second locking sections are rotated to adapt to the angle of the hood. The locking state of the second locking plate 122b is achieved by passing fasteners through the fastening holes at the ends of the two second locking sections.

[0104] For example, the fastener can be a long bolt, and the fastening hole can be a bolt locking hole.

[0105] For example, by detachably connecting the second locking section to the second mounting connection 121 via fasteners, the stability of repeated installation and disassembly of various parts of the painting equipment when matching different hoods is solved. This facilitates subsequent maintenance and reduces maintenance costs.

[0106] For example, in order to improve the connection strength between the tailgate and the hood and the workpiece mounting frame 140, the tailgate can be connected to the second connecting rod 121a by wire, and the hood can be connected to the first connecting rod 111a by wire.

[0107] As one feasible implementation, both the first adjustment hole and the second adjustment hole are elongated holes, the first direction is the extension direction of the workpiece mounting frame 140, and the first direction and the second direction intersect each other.

[0108] For example, refer to Figure 3 and Figure 5As shown, the first connecting plate 112a is used to connect with the rear door hinge portion. The first connecting plate 112a includes a first fixed section and a first adjusting section that are connected to each other. Considering the versatility of the painting equipment, and to better match the rear door hinge and the position of the hinge hole on the rear door hinge, the first fixed section is used to fix and connect the first plate to a part of the rear door hinge. According to the position difference of different rear door hinge holes, the first adjusting section is used to connect the first plate to another part of the rear door hinge.

[0109] For example, refer to Figure 5 As shown, a hinge hole of the back door can be connected to the first fixing hole of the first fixing section by a wire to perform the first positioning of the back door. Then, according to the position difference of the hinge holes of the back door, the remaining hinge holes of the back door can be connected to the first adjusting hole of the first adjusting section by a wire, thereby realizing the connection between the back door and the first connecting plate 112a.

[0110] For example, refer to Figure 3 As shown, the extension direction of the first adjusting hole is along Figure 3 As shown in the X direction, the first adjustment hole is set as an elongated oval hole, which can be adapted to the hinge hole of the back door in different positions. This allows different back doors to be connected to the first connecting plate 112a, improving versatility.

[0111] For example, refer to Figure 3 and Figure 7 As shown, the second connecting plate 122a is used to connect with the hinge part of the hood. The second connecting plate 122a includes a second fixed section and a second adjusting section that are connected to each other. Considering the universality of the painting equipment and to better match the hinge position of the hood, the second fixed section is used to fix the hood to the hood. According to the position difference of the hinge hole of different hoods, the second adjusting section is used to connect the hood hinge.

[0112] For example, refer to Figure 7 As shown, a hinge hole on the tailgate and a second fixing hole on the second fixing section can be connected by a wire to perform the initial positioning of the hood. Subsequently, based on the positional differences of the hinge holes on the hood, the remaining hinge holes on the hood and the second adjusting hole on the second adjusting section can be connected by a wire. This achieves the connection between the hood and the second connecting plate 122a.

[0113] For example, refer to Figure 3 As shown, the extension direction of the second adjusting hole is along Figure 3 As shown in the Z direction, the first adjustment hole is set as an elongated hole, which can be adapted to the hinge hole of the back door in different positions. This allows different back doors and the second connecting plate 122a to be connected, improving versatility.

[0114] For example, refer to Figure 3As shown, the first direction is Figure 3 The X direction is shown, and the second direction is... Figure 3 The Z-direction shown can be perpendicular to the first and second directions to facilitate the mounting of the tailgate and hood onto the workpiece mounting frame 140.

[0115] As one feasible implementation, the workpiece mounting assembly 100 further includes a limiting member 130, which includes a limiting support beam 131, a limiting beam adjustment part 132, and a limiting locking connection part 133; the limiting locking connection part 133 is connected to the second mounting connection part 121.

[0116] The limiting locking connection part 133 is slidably connected to the limiting beam adjustment part 132; the limiting support beam 131 is located in the middle section of the limiting beam adjustment part 132.

[0117] For example, refer to Figure 3 and Figure 8 As shown, the limiting beam adjustment part 132 along Figure 3 Extending in the Y direction as shown, a limiting support beam 131 is provided at one end of the limiting beam adjustment part 132, which is used to abut against the hood; a limiting locking connection part 133 is provided at the bottom of the limiting beam adjustment part 132, and a groove is provided at the bottom of the limiting beam adjustment part 132, with the groove facing the limiting locking connection part 133. The limiting locking connection part 133 can slide in the groove. By providing a locking part in the limiting beam adjustment part 132, the position of the limiting locking connection part 133 in the groove can be fixed.

[0118] As one feasible implementation, the limiting locking connection part 133 includes a limiting locking connection plate, a limiting locking connection block and a limiting locking connection rod connected in sequence.

[0119] The limiting locking connecting plate is slidably connected to the limiting support beam 131; the limiting locking connecting rod is connected to the second connecting lug 121b.

[0120] For example, refer to Figure 3 and Figure 8 As shown, the limiting locking connecting rod can be a U-shaped locking threaded rod. The U-shaped locking threaded rod has a U-shaped groove, and its outer wall is threaded. The limiting locking connecting block has a threaded opening through which the U-shaped locking threaded rod can pass. The U-shaped locking threaded rod, which passes through the threaded hole, can be screwed onto the limiting locking connecting block using a nut.

[0121] For example, when connecting the limiting locking connecting rod to the second connecting ear 121b, the U-shaped locking threaded rod is placed at the second connecting ear 121b, and the second connecting ear 121b is fitted into the U-shaped groove formed by the U-shaped locking threaded rod. The position of the U-shaped locking threaded rod in the limiting locking connecting block is adjusted. After adjusting the U-shaped locking rod to the desired position, the U-shaped locking threaded rod and the limiting locking connecting block are screwed together using a nut. This not only achieves the connection between the limiting locking connecting rod and the second connecting ear 121b, but also provides a detachable connection between the limiting locking connecting rod and the limiting locking connecting block, which is beneficial for future maintenance.

[0122] For example, refer to Figure 3 and Figure 8 As shown, the limiting and locking connecting plate edge Figure 3 Extending in the Z direction as shown, the first end of the limiting and locking connecting plate is welded to the limiting and locking connecting block, and the second end of the limiting and locking connecting plate is slidably connected to the limiting beam adjusting part 132. The limiting support beam 131 extends along... Figure 3 The position of the limiting support beam 131 can be adjusted by moving it in the Y direction to match different hoods. When it is necessary to fix the position of the limiting support beam 131, the limiting beam adjustment part 132 and the limiting locking connection part 133 are fastened together by bolts and nuts, so that the limiting support beam 131 abuts against the hood to achieve the supporting function of the hood.

[0123] As one possible implementation, the skid connection assembly 200 includes a bracket beam 201, a support portion 202, a ground support portion 203, and a skid connection portion 204.

[0124] The top of the bracket beam 201 is connected to the bottom of the operating platform 300, and the bracket beam 201 is provided with a skid connection part 204 away from the bottom of the operating platform 300; the support part 202 and the ground support part 203 are respectively provided at different positions of the bracket beam 201.

[0125] The support part 202 has a support groove on the side opposite to the operating platform 300.

[0126] For example, refer to Figure 9 and Figure 10 As shown, to achieve mobility of the coating equipment, a skid connecting assembly 200 is installed at the bottom of the operating platform 300, connecting the skid connecting assembly 200 to the operating platform 300. When the coating equipment needs to be moved on the production line, workers can use a forklift to move the coating equipment equipped with the skid connecting assembly 200 to the designated location, improving the work efficiency of the production line and making reasonable use of the workshop production space.

[0127] For example, when the forklift moves the coating equipment, the forklift's forks insert into the support grooves of the support portion 202, and the forks lift the coating equipment to move it. By setting up the support portion 202, wherein two support portions 202 are correspondingly set at the bottom of the operating platform 300, the stability of the forklift's forks lifting the coating equipment is improved, friction damage caused by direct contact between the forks and other parts is avoided, and the service life of the coating equipment is increased.

[0128] For example, the bottom of the skid connection assembly 200 is provided with a ground support 203. When the coating equipment is moved to the designated position, in order to avoid frictional damage caused by direct contact between the operating platform 300 and the ground, the ground support 203 can increase the friction between the ground and the operating platform 300, thereby improving the service life of the coating equipment. In addition, by providing the ground support 203, the contact area between the bottom of the coating equipment and the ground can be increased, thereby increasing the stability of the coating setup.

[0129] For example, after the forklift places the painting equipment on the production line track, the skid connection part 204 at the bottom of the skid connection assembly 200 locks with the track, improving the stability of the painting equipment on the track. The skid connection part 204 may be provided with skid connection holes, which are locked with pins on the track, thus fixing the painting equipment on the track.

[0130] Secondly, this application provides a coating system, including a coating liquid tank, a track, and coating equipment.

[0131] The skid connection assembly 200 of the coating equipment is slidably connected to a track, at least a portion of which is located within the coating liquid tank.

[0132] For example, in a painting system, a worker can use a forklift to move the painting equipment equipped with the skid connection assembly 200 to a designated position. The worker adjusts the position of the installation adjustment part of the painting equipment as needed, installs the tailgate and hood into the installation adjustment part, and then fixes the tailgate and hood. Subsequently, the worker uses a forklift to move the painting equipment with the tailgate and hood installed into the track. By locking the skid connection part 204 of the skid connection assembly 200 to the track, the painting equipment can follow the moving track into the coating liquid tank to carry out the painting process.
