[0052] Figure 1 A schematic diagram of the three-dimensional structure of a spraying fixture according to an embodiment of the present application is shown; Figure 2 Shows Figure 1 A schematic diagram of the local enlarged structure at point A in the figure; for ease of explanation, only the content related to the embodiment of the present application is shown.

[0053] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides a spray hanger 100 for hanging a tool box cover. The spray hanger 100 includes a base 110, a mounting frame 120, a plurality of hanging parts 130 and a plurality of fixing parts 140.

[0054] The base 110 is a component used to carry other components of the spray rack 100. The base 110 can be configured as a plate or as Figure 1 The frame shape shown can be set according to actual usage and is not specifically limited here.

[0055] The mounting frame 120 is a component for mounting the hanging member 130 and the fixing member 140. The mounting frame 120 includes a plurality of mounting members 121 and a supporting member 122. All the mounting members 121 are arranged longitudinally along the first direction F1 and are arranged in sequence along the second direction F2. The first direction F1 and the second direction F2 intersect each other. Along the second direction F2, the first mounting member 121 is connected to the base 110, and the remaining mounting members 121 are connected to the first mounting member 121 by means of the supporting member 122. Figure 1For example, the first mounting member 121 is the first mounting member 121a, and the last mounting member 121 is the second mounting member 121b. It can be understood that the first mounting member 121 and the last mounting member 121 are relative.

[0056] The hanging member 130 is a component for hanging the tool box cover. A plurality of hanging members 130 are arranged at intervals along the first direction F1 on each mounting member 121 except the first mounting member 121. That is, a plurality of hanging members 130 are arranged at intervals along the first direction F1 on all mounting members 121 except the first mounting member 121a.

[0057] The fixing member 140 is a component used to cooperate with the hanging member 130 to limit and fix the tool box cover. A plurality of fixing members 140 are arranged at intervals along the first direction F1 on each mounting member 121 except the last mounting member 121 along the second direction F2. That is, a plurality of fixing members 140 are arranged at intervals along the first direction F1 on all mounting members 121 except the second mounting member 121b.

[0058] Combined with reference Figure 2 , among the two adjacent mounting members 121 along the second direction F2, each fixing member 140 on the upstream mounting member 121 corresponds to two adjacent hanging members 130 on the downstream mounting member 121, and each fixing member 140 and the corresponding two hanging members 130 are used to fix a tool box cover. In the embodiment of the present application, the second direction F2 can be a vertical direction, and the fixing member 140 is located below the corresponding two hanging members 130, which is more conducive to the hanging and fixing operation of the operator.

[0059] By arranging the hanging parts 130 and the fixing parts 140 on the corresponding mounting parts 121, and making the corresponding hanging parts 130 and fixing parts 140 on two adjacent mounting parts 121 form a structure for fixing the toolbox cover, the fixing of the toolbox cover is achieved. Since all the mounting parts 121 are provided with corresponding hanging parts 130 and fixing parts 140, a plurality of structures that can be used to fix the toolbox cover are formed, so that there is no need to use the vehicle body to carry the toolbox cover, which is conducive to the batch fixing of the toolbox cover and batch spraying of the toolbox cover. In addition, since each fixing part 140 and the corresponding two hanging parts 130 form a structure for fixing a toolbox cover, the toolbox cover can be first hung on the two hanging parts 130 and then fixed by the fixing parts 140, forming a hanging point that is convenient for hanging, and then facilitating the hanging, fixing and disassembling of the toolbox cover, which can be adapted to the spraying process of batch spraying the toolbox cover.

[0060] Compared with the situation where the toolbox cover is sprayed together with the vehicle body, resulting in a low spraying yield of the toolbox cover, and the situation where a scrapped vehicle is used to carry the toolbox cover, resulting in a low spraying efficiency, the spray rack 100 provided in the embodiment of the present application can not only improve the efficiency of spraying the toolbox cover, thereby improving the overall production efficiency, but also improve the spraying yield of the toolbox cover.

[0061] In some embodiments, please refer to Figure 1 , a plurality of support members 122 are provided. All support members 122 are provided to extend longitudinally along the second direction F2 and are arranged in sequence and spaced apart along the first direction F1. Each support member 122 is connected to any one of all mounting members 121. Along the second direction F2, two adjacent mounting members 121 define an installation space. All support members 122 divide the installation space into a plurality of sub-installation spaces Q arranged in sequence along the first direction F1. The fixing member 140 and the corresponding two hanging members 130 constitute a hanging unit, each sub-installation space Q corresponds to a hanging unit, and each hanging unit is used to fix a toolbox cover in the sub-installation space Q. That is, all support members 122 and all mounting members 121 roughly form a grid-like structure. All sub-installation structures 141 constitute the hollowed-out portion or the open hole portion of the aforementioned grid-like structure.

[0062] In this way, since a plurality of sub-installation spaces Q are formed, the installation space can be divided into a plurality of areas, so that the tool box cover can be installed one-to-one, thereby improving the convenience of operation for the operator.

[0063] In some embodiments, please refer to Figure 1 All the sub-installation spaces Q are arranged in columns along the first direction F1 and in rows along the second direction F2.

[0064] In this way, since a more regular sub-installation space Q is formed, when a toolbox cover is installed in each sub-installation space Q, all the toolbox covers can be arranged in a more regular form, which is conducive to the spraying process and can improve the spraying efficiency and spraying effect.

[0065] In some embodiments, please refer to Figure 1 , the first direction F1 and the second direction F2 are perpendicular to each other.

[0066] In this way, since the first direction F1 and the second direction F2 are perpendicular to each other, all sub-mounting structures 141 are roughly arranged in a matrix, so that all tool box covers can be arranged in a more regular form, further improving the operating convenience and spraying convenience, thereby improving the spraying efficiency and spraying effect.

[0067] In some embodiments, please refer to Figure 1, the orthographic projection of the fixing member 140 on the reference plane is the first projection, and the orthographic projections of the two hanging members 130 corresponding to the fixing member 140 on the reference plane are the second projection and the third projection respectively. The reference plane is a plane perpendicular to the second direction F2. Along the first direction F1, the first projection is located between the second projection and the third projection.

[0068] In this way, the fixing member 140 and the corresponding two hanging members 130 can form a more stable hanging and fixing structure, which is beneficial to the hanging and fixing of the tool box cover and can improve the stability of the tool box cover during the spraying process.

[0069] In some embodiments, please refer to Figure 1 , taking the case where three mounting members 121 are provided as an example, a portion of each sub-mounting space Q defined by the middle mounting member 121 is provided with a hanging member 130, a fixing member 140 and another hanging member 130 in sequence along the first direction F1. A fixing member 140 is provided on a portion of each sub-mounting space Q defined by the first mounting member 121a. Two hanging members 130 are provided along the first direction F1 on a portion of each sub-mounting space Q defined by the second mounting member 121b. The fixing members 140 on the middle mounting member 121 and the fixing members 140 on the first mounting member 121a are provided in a one-to-one correspondence along the second direction F2. The hanging members 130 on the middle mounting member 121 and the hanging members 130 on the second mounting member 121b are provided in a one-to-one correspondence along the first direction F1.

[0070] In this way, the overall structure can be made more compact and the space occupied by the spray rack 100 can be reduced.

[0071] In some embodiments, please refer to Figure 1 The tool box cover has a first process hole matched with the hanging member 130. The hanging member 130 includes a hanging section 131 and a fixing section 132 which are sequentially arranged and connected along the second direction F2. A hook portion 131a is provided at one end of the hanging section 131 away from the fixing section 132. The hook portion 131a is a component arranged in a hook shape. The hook portion 131a is used to match with the first process hole to hang the tool box cover, and the fixing section 132 is fixedly connected to the corresponding mounting member 121.

[0072] In this way, by providing the hook portion 131a on the hanging member 130 and utilizing the first process hole on the tool box cover, it is not only convenient to hang the tool box cover, but also makes the overall structure simpler and more operable.

[0073] Figure 3 Shows Figure 1 Schematic diagram of the structure of the fixing member 140 shown in the figure; for the convenience of explanation, only the content related to the embodiment of the present application is shown.

[0074] In some embodiments, please refer to Figure 1 , and combined with reference Figure 3 The toolbox cover has a second process hole that matches the fixing member 140. The fixing member 140 includes a mounting structure 141, a first limiting member 142 and a connecting member 143. The mounting structure 141 is fixedly connected to the corresponding mounting member 121. The first limiting member 142 is arranged on the mounting structure 141. A first through hole k1 is opened on the first limiting member 142 along the third direction F3. The connecting member 143 includes a threaded segment L1 and a limiting portion L2 connected to the threaded segment L1. The threaded segment L1 is movably arranged in the first through hole k1 along the third direction F3 and is used for threaded connection with the inner wall of the second process hole. The limiting portion L2 can abut against the limiting member. The first direction F1 and the second direction F2 are both perpendicular to the third direction F3.

[0075] In this way, since the threaded section L1 is provided on the connecting member 143, the connecting member 143 can be fixedly connected with the second process hole of the tool box cover plate in a threaded matching manner, thereby fixing the tool box cover plate. At the same time, since the first limiting member 142 can be abutted and matched with the limiting portion L2 on the connecting member 143, it is convenient for the operator to connect the connecting member 143 and the tool box cover plate.

[0076] In some embodiments, please refer to Figure 1 , and combined with reference Figure 3 The fixing member 140 also includes a second limiting member 144 provided on the mounting structure 141. The second limiting member 144 and the first limiting member 142 are arranged opposite to each other along the third direction F3. A second through hole k2 corresponding to the first through hole k1 is provided on the second limiting member 144 along the third direction F3. In the direction in which the threaded segment L1 is inserted into the second process hole, the second limiting member 144 is located upstream of the first limiting member 142. The limiting portion L2 is limited between the first limiting member 142 and the second limiting member 144. The threaded segment L1 includes a first segment L11, a second segment L12 and a third segment L13 connected in sequence, and the limiting portion L2 is provided on the second segment L12. The first segment L11 is movably provided in the first through hole k1 along the third direction F3, and the third segment L13 is movably provided in the second through hole k2 along the third direction F3.

[0077] In this way, by providing the second limiting member 144, the possibility of the fixing member 140 being lost can be improved when the tool box cover is not hung, thereby improving the convenience of use.

[0078] In some embodiments, please refer to Figure 1 , and combined with reference Figure 3 The fixing member 140 further includes an operating member 145 disposed at an end of the third segment L13 away from the second segment L12. The operating member 145 is located at a side of the second stopper 144 away from the first stopper 142. The operating member 145 can be configured as Figure 3 The longitudinal member shown in the figure can also be set in other forms, which are not specifically limited here.

[0079] In this way, by providing the operating member 145 , it is convenient for an operator to rotate the connecting member 143 by means of the operating member 145 , thereby achieving the connection between the connecting member 143 and the tool box cover.

[0080] It should be noted that the above only illustrates some embodiments of the fixing member 140, and the fixing member 140 may also adopt a detachable connection structure such as a locking member, as long as it can fix the tool box cover, and no specific limitation is made here.

[0081] In some embodiments, the material of each component of the spray rack 100 can be Q235 steel. In this way, it has a certain high temperature resistance and can increase the service life of the entire device.

[0082] Based on the same inventive concept, an embodiment of the present application provides a spraying line equipment, including a spraying robot and a spraying hanger 100 in any of the above embodiments, wherein the spraying robot is used for spraying a tool box cover fixed on the spraying hanger 100 .

[0083] After the operator has hung and fixed the tool box cover, the spraying robot can perform spraying operations on the tool box cover hung and fixed on the spraying hanger 100 according to the preset relevant procedures.

[0084] The advantages of the spray rack 100 illustrated in the above embodiments are also possessed by the spray line equipment, which will not be described in detail here.

[0085] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
