Abstract
Description
Technical Field
[0001] The present application relates to the technical field of automobile welding production lines, and in particular to a production system and production equipment. Background Art
[0002] The automobile manufacturing process is divided into five processes: stamping, welding, painting, assembly and testing. Among them, the welding process is to weld the cabin, front floor, rear floor and other parts into the entire car body. During the welding process, processing equipment is required to first splice and fix the various parts, and then weld them.
[0003] These processing equipment need to be calibrated regularly using test equipment such as articulated arm test equipment or laser trackers. Due to the limited length of the test equipment, the test equipment can only be installed on the feet on both sides of the production line. When testing the test equipment, it is necessary to first fix it on the foot on one side, then establish the coordinate system, and then fix the test equipment to the foot on the other side, and then establish the coordinate system with multiple frog jumps. In addition, the test equipment is affected by the roller bed during measurement, and there are blind spots, which also requires multiple frog jumps to establish the coordinate system.
[0004] This measurement method uses multiple frog leaps to transpose and establish a coordinate system, which can lead to large measurement errors. This prevents the support surfaces or support columns on the processing equipment from fitting closely together, and the processing equipment from properly splicing the various components. This ultimately leads to the inability to weld or large welding errors, affecting the product qualification rate. Utility Model Content

[0032] The automobile manufacturing process is divided into five processes: stamping, welding, painting, assembly and testing. Among them, the welding process is to weld the cabin, front floor, rear floor and other parts into the entire car body. During the welding process, processing equipment is required to first splice and fix the various parts, and then weld them.
[0033] In order to solve the technical problems existing in the related technology, this application provides a production system, see Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of the production system provided by the present application.
[0034] The production system 10 includes a processing device 130 and a production device 100, wherein the processing device 130 is fixed to the production device 100. The processing device 130 can fix each product to be moved (not shown), and the processing device 130 is used to dock the fixed products to be moved with each other. However, before using the processing device 130, a coordinate system needs to be established to measure the processing device 130 to ensure accurate docking between the products to be moved.
[0035] However, in the relevant embodiment, when the coordinate system of the processing equipment 130 is established for measurement, the coordinate system needs to be established twice using the leapfrog method. This method of establishing coordinates will result in large measurement errors due to the use of multiple leapfrogs for transposition, and the support surface or support column on the processing equipment 130 cannot be closely matched, and then the processing equipment 130 cannot perform good docking with each product to be moved, which ultimately leads to the inability to weld or large welding errors, affecting the product qualification rate. In order to solve the technical problems existing in the related art, the present application also provides a production device 100.
[0036] See also Figure 2 and Figure 3 , Figure 2 yes Figure 1 A first perspective view of the production equipment shown. Figure 3 yes Figure 1 A second perspective view of the production equipment shown.
[0037] The production equipment 100 includes a conveying platform 200, two footrests 110 and a measuring bracket 120. The conveying platform 200 is used to convey the product to be moved along a first direction X. The two footrests 110 are located on both sides of the conveying platform 200 in a second direction Y perpendicular to the first direction X, each footrest 110 is extended along the first direction X, and each footrest 110 is provided with a reference point 111. The measuring bracket 120 is connected to the two footrests 110, and the measuring bracket 120 is used to carry the test equipment so that the test equipment simultaneously collects the reference points 111 on the two footrests 110.
[0038] The conveying platform 200 can be used to place the products to be moved. A plurality of pulleys are provided on the conveying platform 200. The pulleys are arranged in parallel and at intervals on both sides of the conveying platform 200 along the first direction X. Thus, the products to be moved can be moved along the first direction X on the conveying platform 200 via the pulleys.
[0039] The production equipment 100 also includes a base, which is located below the conveying platform 200. The base is used to carry the conveying platform 200, and can move the conveying platform 200 in a third direction perpendicular to the first direction X and the second direction Y, so that the product to be moved placed on the conveying platform 200 moves upward, so that the processing equipment 130 fixes the product to be moved. Two footrests 110 are provided on the base, and the footrests 110 can be used to install different types of processing equipment 130. The two footrests 110 are respectively located on both sides of the conveying platform 200 in the second direction Y. The heights of the two footrests 110 are the same, and the heights of the two footrests 110 are lower than the height of the conveying platform 200. The two footrests 110 are provided with a plurality of reference points 111 at intervals in the first direction X. The reference point 111 is a circular groove, and a protective cover is provided on the circular groove to protect the reference point 111 from being deformed by external force and avoid deviation of the reference point 111. The reference point 111 can also be a triangle or a square, and the present application does not limit the shape of the reference point 111. In some embodiments, the number of reference points 111 set on the production equipment 100 can be at least 4, and two reference points 111 are set on each of the two footrests 110. The reference points 111 on one footrest 110 are set at a maximum interval of 1 meter to ensure that the coordinate system can be established. The reference points 111 on the two footrests 110 can be set symmetrically. The number of reference points 111 is not fixed and can be set according to the length of the footrest 110.
[0040] The two ends of the measuring bracket 120 are respectively connected to a foot 110, and the height of the measuring bracket 120 is higher than the conveying platform 200. The measuring bracket 120 carries a test device (not shown) so that the test device can be located above the middle of the conveying platform 200. The test device is used to collect information of the reference points 111 located on the two foots 110. Without moving the test device, the collection end of the test device can collect information of the reference points 111 located on the two foots 110.
[0041] Through the above-mentioned embodiment, the two feet are located on both sides of the conveying platform 200 in the second direction Y, and the measuring bracket 120 is connected to the two feet 110, so that the measuring bracket 120 is bridged above the conveying platform 200, so that the test equipment carried on the measuring bracket 120 can also be located above the conveying platform 200, and each foot 110 is provided with a reference point 111, which can facilitate the establishment of a coordinate system based on the reference point 111 by the test equipment, so as to achieve the purpose of establishing the coordinate system at one time, thereby reducing the loss of accuracy caused by leaping before measurement.
[0042] See also Figure 4 and Figure 5 , Figure 4 yes Figure 1 The first view of the measuring bracket shown, Figure 5 yes Figure 1 A second viewing angle of the measuring bracket is shown.
[0043] In some embodiments, the measuring bracket 120 includes two bases 122 and a support member 121. The two bases 122 are respectively arranged on the footrests 110 on both sides of the conveying platform 200 along the second direction Y. One base 122 is connected to each end of one side of the support member 121. The support member 121 is used to carry the test equipment. The base 122 is higher than the height of the conveying platform 200 to ensure that the height of the support member 121 is higher than the conveying platform 200. Therefore, one base 122 is connected to each end of one side of the support member 121, and the two bases 122 are respectively connected to a footrest 110, so that the support member 121 can be located above the conveying platform 200, and the test equipment can be placed above the support member 121, thereby making the test equipment located above the conveying platform 200. If there is no measuring bracket 120, the test platform can only be placed on the footrest 110. When establishing the coordinate system, due to the obstruction of the conveying platform 200, the test equipment can only collect the reference points 111 of the foot 110 on one side first, and then use the frog leaping method to place the test equipment on the foot 110 on the other side to establish the coordinate system. However, by placing the test equipment above the conveying platform 200, the conveying platform 200 avoids the obstruction of the test equipment, and the test equipment can collect the reference points 111 on the two foots 110 at one time, avoiding the frog leaping method to establish the coordinate system twice, thereby improving the measurement accuracy of the processing equipment 130.
[0044] In some embodiments, the support member 121 includes four hollow tubes with a square cross-section, two of which are parallel, one end of which is connected to a base 122, and the other end is connected to another base 122, and the length is equal to or greater than the distance between the two footrests 110, so that the support member 121 can span the conveying platform 200. The other two hollow tubes are supported between the two hollow tubes connected to the base 122, which has the effect of strengthening stability, and the length of the two hollow tubes with the effect of strengthening stability is less than the length of the two hollow tubes connected to the base 122. The hollow design of the support member 121 can reduce the weight of the support member 121 and facilitate the installation of the support member 121. The two hollow tubes with the effect of strengthening stability can improve the stability of the support member 121 and avoid shaking when the test equipment is working. The present application does not limit the shape of the support member 121.
[0045] In some embodiments, the measuring bracket 120 further includes a support platform 1212, which is a square flat plate. The support platform 1212 is fixedly connected to a side of the support member 121 away from the conveying platform 200, and the support member 121 can carry the test equipment through the support platform 1212. The test equipment is placed on the support platform 1212, which can improve the stability of the test equipment. The support platform 1212 can be set in the middle of the support member 121, so that the collection end of the test equipment can collect the reference point 111 on the foot seat 110 on one side of the conveying platform 200, and can also collect the reference point 111 on the foot seat 110 on the other side, so that the reference point 111 on both sides of the conveying platform 200 can be collected at one time, without using the leapfrog method to establish a coordinate system twice. One end of the support platform 1212 can extend along the first direction X, and the measurement distance of the test equipment in the first direction X can be increased by changing the position of the test equipment on the support platform 1212.
[0046] In some embodiments, the base 122 includes a support column 1221 and a first connecting plate 1222. One end of the support column 1221 is connected to the foot 110, and the other end extends in a direction away from the foot 110, and the end away from the foot 110 is fixedly connected to one side of the first connecting plate 1222. The other side of the first connecting plate 1222 is connected to the support member 121. The height of the support column 1221 is greater than the height of the conveying platform 200, so that the height of the measuring bracket 120 can be higher than the conveying platform 200. In some embodiments, the structure of the support column 1221 can be the same as that of the support member 121, and the support column 1221 can include four hollow tubes with a square cross section. One end of two of the hollow tubes is connected to the foot 110, and the other end is fixedly connected to the first connecting plate 1222. The other two hollow tubes are supported between the two hollow tubes connected to the foot 110 and the first connecting plate 1222. The height of the two hollow tubes connected to the foot base 110 and the first connecting plate 1222 is higher than the conveying platform 200, so that the distance from the support platform 1212 to the conveying platform in the third direction can be approximately half of the distance from the end of the processing equipment 130 away from the foot base 110 to the conveying platform 200, thereby allowing the entire processing equipment 130 to be located within the measurement range of the testing equipment.
[0047] In some embodiments, the base 122 further includes a fixing plate 1223. In the support column 1221, two hollow tubes supported between the foot 110 and the support member 121 are fixedly connected to the foot 110 through the fixing plate 1223. The support column 1221, the fixing plate 1223, and the first connecting plate 1222 can be connected by welding, so that the support column 1221, the fixing plate 1223, and the first connecting plate 1222 are fixedly connected as a whole, so that the stability of the base 122 is better when subjected to external force, so that the support column 1221, the first connecting plate 1222, and the fixing plate 1223 are more secure. The radial dimension of the fixing plate 1223 can be greater than the radial dimension of the two hollow tubes, so that the contact surface between the fixing plate 1223 and the foot 110 is larger, which brings better stability to the support column 1221.
[0048] In some embodiments, the fixing plate 1223 and the foot 110 are detachably connected. The fixing plate 1223 and the foot 110 may be provided with threaded holes, and the fixing plate 1223 may be detachably connected to the foot 110 by screws. When the processing equipment 130 of the production system 10 needs to be measured or after the measurement is completed, the measurement bracket 120 can be installed or removed, so as not to affect the transportation of the product to be moved by the production system 10, and further not to affect the fixing and welding of the product to be moved.
[0049] In some embodiments, there may be a plurality of support columns 1221, and the plurality of support columns 1221 are arranged at intervals along the first direction X, and the plurality of support columns 1221 are respectively connected to the first connecting plate 1222. The plurality of support columns 1221 are supported between the support member 121 and the fixing plate 1223, which can improve the stability of the measuring bracket 120. In some embodiments, the number of support columns 1221 may be two. The two support columns 1221 have the same size so that the first connecting plate 1222 and the fixing plate 1223 fixedly connected to the support columns 1221 are parallel to each other, so that the test equipment is in a horizontal position. A reinforcing column may be provided between the two support columns 1221 to improve the stability of the support columns 1221, thereby making the support member 121 more stable.
[0050] In some embodiments, the support member 121 includes a support beam 1211 and a second connecting plate 1213, the support beam 1211 is composed of the above-mentioned four square hollow tubes, and the support beam 1211 is extended along the second direction Y. The second connecting plates 1213 are arranged at intervals in the second direction Y and are respectively connected to the support beam 1211. The support beam 1211 and the second connecting plate 1213 and the support platform 1212 can be fixedly connected together by welding, so that the support beam 1211, the second connecting plate 1213 and the support platform 1212 are integrated. The support beam 1211 is connected to the first connecting plate 1222 connected to the two bases 122 through the two second connecting plates 1213. The radial dimension of the second connecting plate 1213 can be the same as the radial dimension of the first connecting plate 1222.
[0051] In some embodiments, the first connecting plate 1222 and the second connecting plate 1213 are detachably connected. Specifically, the first connecting plate 1222 and the second connecting plate 1213 can be connected by screws to facilitate the installation and removal of the measuring bracket 120. In some embodiments, the second connecting plate 1213 and the supporting beam 1211, the supporting beam 1211 and the supporting platform 1212, the supporting column 1221 and the first connection, and the supporting column 1221 and the fixing plate 1223 can be connected by welding, so that the measuring bracket 120 is divided into two parts, namely, the support member 121 and the base 122. The support member 121 and the base 122 are connected by screws. Thus, when the processing equipment 130 needs to establish a coordinate system for the test equipment and perform calibration measurement or calibration, the base 122 can be first installed on the footrest 110 by screws, and then the support member 121 can be detachably installed on the base 122 through the first connecting plate 1222 and the second connecting plate 1213.
[0052] To summarize, the two feet 110 are located on both sides of the conveying platform 200 in the second direction Y, and the measuring bracket 120 is connected to the two feet 110, so that the measuring bracket 120 is bridged above the conveying platform 200, so that the test equipment carried on the measuring bracket 120 can also be located above the conveying platform 200, and each foot 110 is provided with a reference point, which can facilitate the establishment of a coordinate system based on the reference point by the test equipment, so as to achieve the purpose of establishing the coordinate system at one time, thereby reducing the loss of accuracy caused by leaping before measurement.
