DETAILED DESCRIPTION

[0021] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined application purpose, the specific embodiments, structures, features and effects according to the present application are described in detail as follows in combination with the drawings and preferred embodiments.

[0022] Please refer to Figs. 1-3The embodiment provides an automatic gluing device for automobile body parts, which comprises a control module 6, a machine table 1, a positioning jig 2 arranged on the top surface of the machine table 1 and a gantry mechanism 3 composed of four sliding tables, wherein a gluing mechanism 4 and a detection mechanism 5 are arranged at the movable end of the Z-axis of the gantry mechanism 3, the control module 6 is in communication connection with the positioning jig 2, the gantry mechanism 3, the detection mechanism 5 and the gluing mechanism 4, and a plurality of sets of gluing programs are preset in the control module 6 and used for gluing different parts.

[0023] The positioning jig 2 comprises quick-change assemblies and a positioning assembly, the positioning assembly is arranged on the top surface of the machine table 1, the quick-change assemblies are detachably connected to the top surface of the positioning assembly, a plurality of quick-change assemblies are arranged and used for fixing different parts and corresponding to the plurality of sets of gluing programs, the positioning assembly is used for positioning the quick-change assemblies and identifying the quick-change assemblies arranged on the top surface of the positioning assembly, the control module 6 calls the corresponding gluing program according to the identification result of the positioning assembly to glue different parts, the detection mechanism 5 detects the deviation of the position of the quick-change assemblies arranged on the positioning assembly during gluing, and the control module 6 corrects the executed gluing program according to the detection result of the detection mechanism 5.

[0024] During gluing of automobile parts, the shapes of the parts to be glued are different and greatly different, so the same set of gluing installation jig can only correspond to one kind of part during gluing, and in order to improve the production efficiency during gluing of a large number of automobile parts and reduce the resource waste caused by setting a plurality of different gluing devices to correspond to different shapes of parts.

[0025] In the present application, by setting several quick change assemblies corresponding to different shapes of parts, different shapes of parts can be installed through different quick change jigs, and all quick change jigs can be installed on the positioning assembly. Different quick change assemblies and different gluing procedures are used to glue different shapes of parts. When different quick change assemblies are installed on the positioning assembly, the positioning assembly determines the position of the quick change assembly and accurately positions it to determine the position of the quick change assembly on the positioning assembly. When gluing, the detection mechanism 5 determines the installation position of the quick change assembly and detects the positioning error during installation. The control module 6 corrects the gluing path of the current gluing procedure based on the detection result of the detection mechanism 5, thereby accurately gluing the parts. Different quick change assemblies correspond to different parts, and different gluing procedures are matched to complete gluing. During the gluing process, the detection mechanism 5 detects the installation position of the quick change assembly to avoid positioning deviation during multiple quick change installations, which may cause installation errors and prevent the preset gluing procedure from accurately gluing the parts. The control module 6 corrects the current gluing path based on the detection result of the detection mechanism 5 to ensure accurate gluing of the parts and avoid gluing deviation.

[0026] Since multiple quick change assemblies are positioned by the positioning assembly, in order to ensure the positioning effect of the quick change assembly and the accuracy of the identification effect of different quick change assemblies, in the present embodiment, the positioning assembly includes a positioning plate 21 and a pressure sensor 22. The positioning plate 21 is installed on the top surface of the machine table 1. The top surface of the positioning plate 21 has a positioning hole. The quick change assembly is detachably installed on the top surface of the positioning plate 21. The pressure sensor 22 is installed on the bottom surface of the positioning plate 21 and is used to detect the pressure applied by the quick change assembly. Since different quick change assemblies correspond to different parts, and different parts have large differences in shape, the shape of the quick change assembly will also vary when fixing different parts. Therefore, the weight of each quick change assembly is not the same. The positioning effect of the positioning hole is used to position the quick change assembly, and the pressure sensor 22 is used to detect the pressure of the quick change assembly on the positioning plate 21. The control module 6 can determine which gluing procedure is being executed to glue the parts, thereby gluing the parts.

[0027] Since the quick-change assembly needs to complete the quick disassembly function on the positioning plate 21 to meet the process of gluing different parts, in order to complete the quick disassembly function faster while maintaining the stability of the quick-change assembly, in an embodiment, the inner bottom surface of the positioning hole is provided with an electromagnet for adsorbing and fixing the quick-change assembly. When the pressure sensor 22 detects that the quick-change assembly is installed on the positioning plate 21, the electromagnet is powered on to adsorb the quick-change assembly in the positioning hole, thereby ensuring that the quick-change assembly can be stable during the gluing process. At the same time, the quick-change assembly is completed by the on-off of the electromagnet, so that different quick-change assemblies can be quickly installed on the positioning plate 21 to complete the gluing of different parts.

[0028] Since different automobile body parts have many curved surfaces, their shapes are complex, in order to better fix the parts on the quick-change assembly, in an embodiment, the quick-change assembly includes a positioning column 23 and a profiling jig plate 24, the profiling jig plate 24 is installed on the top surface of the positioning column 23, and the positioning column 23 is installed in the positioning hole. The profiling jig plate 24 is used to fix the parts to be glued, and the positioning of the profiling jig plate 24 is completed by matching the positioning column 23 with the positioning hole, so that the profiling jig plate 24 is used to accurately position and fix the parts. Moreover, the profiling jig plate 24 is designed according to the shape of the parts, so that the parts can be better fixed, and the parts cannot be better fixed due to the many curved surfaces of the parts, so as to avoid the shaking during the gluing process.

[0029] Although the profiling jig plate 24 is designed according to different parts, it cannot be ensured that the profiling jig plate 24 manufactured will have a difference in weight, therefore, in order to better distinguish different profiling jig plates 24 so that the control module 6 can accurately match different gluing programs, in an embodiment, the bottom surface of the profiling jig plate 24 is provided with a plurality of counterweights 25. By setting different configuration blocks on the profiling jig plate 24, the results detected by the pressure sensor 22 can be better distinguished, thereby avoiding the situation that the pressure values applied by similar parts corresponding to the profiling jig plate 24 are similar, and the parts cannot be accurately distinguished, thereby causing the gluing program to be called incorrectly and the current parts to be glued.

[0030] In order to better complete the gluing of the parts, in an embodiment, the gluing mechanism 4 comprises a glue cylinder 41, a glue head 42 and a fixing seat 43, the glue cylinder 41 and the fixing seat 43 are both installed on the movable end of the Z-axis of the gantry mechanism 3, the glue head 42 is adjustably installed on the top surface of the fixing seat 43, the glue cylinder 41 is communicated with the glue head 42 through a glue pipe, the gluing action is better completed by adjusting the position of the glue head 42 on the fixing seat 43, and the glue cylinder 41 continuously provides glue for the gluing of the glue head 42, so that the continuity in the gluing process is ensured, and the situation of glue breakage is avoided.

[0031] Since the parts have many curved surfaces, the shape of the parts is not regular, therefore, in order to better glue different positions of the parts, in an embodiment, the gantry mechanism 3 comprises a Z-axis sliding table 31, an X-axis sliding table 32, two Y-axis sliding tables 33 and two support seats 34, the two Y-axis sliding tables 33 are respectively installed on the top surface of the machine table 1 through the two support seats 34, the X-axis sliding table 32 is installed on the movable end of the two Y-axis sliding tables 33, and the Z-axis sliding table 31 is installed on the movable end of the X-axis sliding table 32, so that the gantry of the four sliding table members is formed, the three-direction movement can be realized through the control of the servo motor, the flexible gluing track is realized, and the situation of gluing dead point is avoided.

[0032] In order to better determine the installation error of the quick-change assembly on the positioning assembly, in an embodiment, the detection mode of the detection mechanism 5 adopts visual detection, since the positioning column 23 needs to be inserted and pulled on the positioning hole when the quick-change assembly is quickly changed, the wear is caused by the multiple insertion and pulling processes, and then the subsequent positioning effect will be deviated, therefore, the position of the profiling jig plate 24 on the positioning plate 21 is detected by the detection mechanism 5, the subsequent gluing program is corrected, the error precision can be better judged by detecting the position of the profiling jig plate 24 on the positioning plate 21, the calibration amount and calibration precision in the detection process are reduced during the positioning of the parts, so that the detection process is better completed, and the detection precision is improved.

[0033] The above is only a preferred embodiment of the present application, and does not limit the present application in any form, although the present application has been disclosed as above with the preferred embodiment, however, it is not intended to limit the present application, any person skilled in the art can make some changes or modifications to the equivalent embodiments with the disclosed technical content without departing from the technical solution range of the present application, as long as it does not depart from the technical solution content of the present application, any brief modification, equivalent change and modification of the above embodiment according to the technical essence of the present application are still within the range of the technical solution of the present application.
