Description

Technical Field

[0001] The utility model belongs to the technical field of welding, and particularly relates to a body-in-white welding production line. Background Art

[0002] The automobile industry is one of the pillar industries in my country, and the car body is one of the core components of the car. In the automobile manufacturing process, the welding of the body-in-white is a relatively important process. The body-in-white includes the chassis and the side panels. The welding of the body-in-white is to weld the bottom plate and the side panels to form a complete body-in-white. The welding of the body-in-white is generally completed through the body-in-white welding production line.

[0003] In the design of the body-in-white welding production line, in addition to ensuring the production rhythm of the body-in-white welding production line, reducing the site requirements of the body-in-white welding production line is also a technical problem that needs to be solved urgently. Utility Model Content

[0004] In view of the above problems, an embodiment of the present application provides a body-in-white welding production line, which can reduce the site requirements of the body-in-white welding production line.

[0005] The embodiment of the present application provides a body-in-white welding production line for welding a body, and the body-in-white welding production line includes a first welding line, a second welding line, a first feeding channel and a first transfer mechanism. The first welding line and the second welding line both extend along a first direction. The first welding line, the first feeding channel and the second welding line are arranged along a second direction. The first feeding channel is used to provide materials to the first welding line and the second welding line. The first direction, the second direction and the direction of gravity are perpendicular to each other. The first transfer mechanism is used to drive the body to move between the first welding line and the second welding line. Wherein, along the second direction, the projection of the first welding line and the projection of the second welding line at least partially overlap.

[0006] In the technical solution of the embodiment of the present application, along the second direction, the projection of the first welding line and the projection of the second welding line at least partially overlap, thereby reducing the size of the body-in-white welding production line in the first direction, thereby reducing the requirements of the body-in-white welding production line for the size of the site in the first direction. At the same time, since the first feeding channel is arranged between the first welding line and the second welding line along the second direction, and since along the second direction, the projection of the first welding line and the projection of the second welding line at least partially overlap, the first feeding channel can simultaneously provide materials to at least part of the first welding line and the second welding line, thereby reducing the size of the first feeding channel in the first direction, and then reducing the area occupied by the first feeding channel, thereby reducing the requirements of the body-in-white welding production line for the site area.

[0007] In some embodiments, along the second direction, the projection of the first welding line and the projection of the second welding line completely overlap.

[0008] In the above scheme, along the second direction, the projection of the first welding line and the projection of the second welding line completely overlap, so that the two ends of the first welding line in the first direction are respectively aligned with the two ends of the second welding line in the first direction. On the one hand, the size of the body-in-white welding production line in the first direction is further reduced, thereby reducing the requirements of the body-in-white welding production line for the size of the site in the first direction; on the other hand, the first feeding channel can simultaneously provide materials to the first welding line and the second welding line as a whole, thereby further reducing the size of the first feeding channel in the first direction, and then further reducing the area occupied by the first feeding channel, thereby further reducing the requirements of the body-in-white welding production line for the site area.

[0009] In some embodiments, along the routing direction of the first welding line, the first welding line has a first end and a second end that are arranged oppositely. Along the routing direction of the second welding line, the second welding line has a third end and a fourth end that are arranged oppositely. The routing directions of the first welding line and the second welding line are both parallel to the first direction, and along the first direction, the third end is aligned with the second end. The first transfer mechanism is used to drive the vehicle body to move from the second end to the third end along the second direction.

[0010] In the above scheme, the third end is aligned with the second end along the first direction, so that the first transfer mechanism can drive the car body to be transferred from the second end to the third end through the shortest distance along the second direction, thereby reducing the time required for the first transfer mechanism to transfer, thereby optimizing the production rhythm of the white body welding production line.

[0011] In some embodiments, the first transfer mechanism includes a guide rail and a first transfer platform, the guide rail extends along the second direction, the first transfer platform is slidably disposed on the guide rail, and is used to grab the vehicle body.

[0012] In some embodiments, the guide rail has a first portion, and along the gravity direction, the first portion is located above the first loading channel. When the first transfer platform is located at the first portion, along the gravity direction, there is a gap between the first transfer platform and the first loading channel for allowing materials to pass.

[0013] In the above scheme, along the direction of gravity, there is a gap between the first transfer platform and the first loading channel for allowing materials to pass through, so that the material can enter the first loading channel from one end of the first loading channel close to the second end of the first welding line and the third end of the second welding line, so that both ends of the first loading channel in the first direction can be used for allowing materials to enter the first loading channel, thereby improving the ability of the first loading channel to provide materials.

[0014] In some embodiments, the first welding line includes a first conveyor line and a plurality of first welding stations, the first conveyor line is used to drive the vehicle body to move from the first end to the second end, and the plurality of first welding stations are arranged at intervals along the first conveyor line. The second welding line includes a second conveyor line and a plurality of second welding stations, the second conveyor line is used to drive the vehicle body to move from the third end to the fourth end, and the plurality of second welding stations are arranged at intervals along the second conveyor line.

[0015] In the above scheme, the car body is driven by the first conveyor line, the first transfer platform and the second conveyor line and passes through the first end, the second end, the third end and the fourth end in sequence, thereby passing through multiple first welding stations and multiple second welding stations in sequence to complete the welding of the car body.

[0016] In some embodiments, the first conveyor line and the second conveyor line are both servo scissor-fork conveyors.

[0017] In some embodiments, the body-in-white welding production line further includes a third welding line, a second feeding channel, and a second transfer mechanism. The third welding line extends along the first direction. The second welding line, the second feeding channel, and the third welding line are arranged along the second direction, and the second feeding channel is used to provide materials to the second welding line and the third welding line. The second transfer mechanism is used to drive the body to move between the second welding line and the third welding line. In the second direction, the projection of the second welding line overlaps with the projection of the third welding line.

[0018] In the above scheme, along the second direction, the projection of the third welding line overlaps with the projection of the second welding line and the projection of the first welding line, thereby reducing the size of the body-in-white welding production line in the first direction, thereby reducing the requirements of the body-in-white welding production line for the size of the site in the first direction.

[0019] In some embodiments, along the routing direction of the third welding line, the third welding line has a fifth end and a sixth end that are arranged opposite to each other, the routing direction of the third welding line is parallel to the first direction, and along the first direction, the fourth end is aligned with the fifth end. The second transfer mechanism is used to drive the vehicle body to move from the fourth end to the fifth end along the second direction.

[0020] In the above scheme, the fourth end is aligned with the fifth end along the first direction, so that the second transfer mechanism can drive the car body to be transferred from the fourth end to the fifth end along the second direction through the shortest distance, thereby reducing the time required for the second transfer mechanism to transfer, thereby optimizing the production rhythm of the white body welding production line.

[0041] The automobile industry is one of the pillar industries in my country, and the car body is one of the core components of the car. In the automobile manufacturing process, the welding of the body-in-white is a relatively important process. The body-in-white includes the chassis and the side panels. The welding of the body-in-white is to weld the bottom plate and the side panels to form a complete body-in-white. The welding of the body-in-white is generally completed through the body-in-white welding production line.

[0042] The body-in-white welding production line includes a body-in-white welding line and a feeding channel. In the prior art, the workstations of the body-in-white welding line are generally arranged in sequence along one direction, and the feeding channel for supplying materials is set on one side of the body-in-white welding line. On the one hand, the size of the body-in-white welding line in the extension direction is too large, thereby increasing the size requirements of the factory building where the body-in-white welding production line is placed in the extension direction. At the same time, the size of the feeding channel in the extension direction is too large, thereby increasing the floor space occupied by the feeding channel, thereby increasing the site area requirements of the body-in-white welding production line.

[0043] In order to solve the above technical problems, refer to Figure 1, an embodiment of the present application provides a white body welding production line 100 for welding a vehicle body. The white body welding production line 100 includes a first welding line 10, a second welding line 20, a first feeding channel 30, and a first transfer mechanism 40. The first welding line 10 and the second welding line 20 both extend along a first direction X. The first welding line 10, the first feeding channel 30, and the second welding line 20 are arranged along a second direction Y. The first feeding channel 30 is used to supply materials to the first welding line 10 and the second welding line 20. The first direction X, the second direction Y, and the gravity direction Z are perpendicular to each other pairwise. The first transfer mechanism 40 is used to drive the vehicle body to move between the first welding line 10 and the second welding line 20. Among them, along the second direction Y, at least part of the projection of the first welding line 10 and the projection of the second welding line 20 overlap.

[0044] The first welding line 10 and the second welding line 20 are two parts that make up the vehicle body line. The first welding line 10 and the second welding line 20 can be used to complete one or more of the welding processes such as vehicle body floor welding, vehicle body side panel welding, and vehicle body engine box welding. Exemplarily, the first welding line 10 and the second welding line 20 can be respectively used for the above-mentioned one process, or the first welding line 10 and the second welding line 20 can jointly complete the above-mentioned one process or more processes.

[0045] It can be understood that both the first welding line 10 and the second welding line 20 are arranged on the floor of the factory building.

[0046] The first direction X and the second direction Y can be horizontal directions. Exemplarily, the first direction X can be parallel to the length direction of the factory building, the second direction Y can be parallel to the width direction of the factory building, or the first direction X can be parallel to the width direction of the factory building, and the second direction Y can be parallel to the length direction of the factory building.

[0047] The first feeding channel 30 is a channel for supplying materials to the first welding line 10 and the second welding line 20.

[0048] In some embodiments, the first feeding channel 30 can be a conveyor belt.

[0049] In some other embodiments, the first feeding channel 30 can be a passage, and workers can supply the shelves with materials to the first welding line 10 and the second welding line 20 through this passage.

[0050] Exemplarily, the above-mentioned materials can be component assemblies such as vehicle body engine box assemblies and vehicle body side panel assemblies, or can also be components such as reinforcing beams and reinforcing plates.

[0051] The first transfer mechanism 40 is a mechanism for driving the vehicle body to move from the first welding line 10 to the second welding line 20, that is, the first transfer mechanism 40 is used to connect the first welding line 10 and the second welding line 20.

[0052] In the technical solution of this embodiment, along the second direction Y, the projection of the first welding line 10 and the projection of the second welding line 20 overlap at least partially, thereby reducing the size of the body-in-white welding production line 100 in the first direction X, thereby reducing the requirements of the body-in-white welding production line 100 for the size of the site in the first direction X. At the same time, since the first feeding channel 30 is arranged between the first welding line 10 and the second welding line 20 along the second direction Y, and since along the second direction Y, the projection of the first welding line 10 and the projection of the second welding line 20 overlap at least partially, the first feeding channel 30 can simultaneously provide materials to at least part of the first welding line 10 and the second welding line 20, thereby reducing the size of the first feeding channel 30 in the first direction X, and further reducing the area occupied by the first feeding channel 30, thereby reducing the requirements of the body-in-white welding production line 100 for the site area.

[0053] According to some embodiments of the present application, referring to Figure 1 , along the second direction Y, the projection of the first welding line 10 and the projection of the second welding line 20 completely overlap.

[0054] In the technical solution of this embodiment, along the second direction Y, the projection of the first welding line 10 and the projection of the second welding line 20 completely overlap, so that the two ends of the first welding line 10 in the first direction X are aligned with the two ends of the second welding line 20 in the first direction X. On the one hand, the size of the body-in-white welding production line 100 in the first direction X is further reduced, thereby reducing the size of the body-in-white welding production line 100 on the site in the first direction X. On the other hand, the first feeding channel 30 can simultaneously provide materials to the first welding line 10 and the second welding line 20 as a whole, thereby further reducing the size of the first feeding channel 30 in the first direction X, and further reducing the area occupied by the first feeding channel 30, thereby further reducing the site area requirement of the body-in-white welding production line 100.

[0055] According to some embodiments of the present application, referring to Figure 1 , along the routing direction N1 of the first welding line 10, the first welding line 10 has a first end 11 and a second end 12 that are arranged oppositely. Along the routing direction N2 of the second welding line 20, the second welding line 20 has a third end 21 and a fourth end 22 that are arranged oppositely. The routing direction N1 of the first welding line 10 and the routing direction N2 of the second welding line 20 are both parallel to the first direction X, and along the first direction X, the third end 21 is aligned with the second end 12. The first transfer mechanism 40 is used to drive the vehicle body to move from the second end 12 to the third end 21 along the second direction Y.

[0056] The routing direction N1 of the first welding line 10 refers to the direction in which the vehicle body moves on the first welding line 10 ; the routing direction N2 of the second welding line 20 refers to the direction in which the vehicle body moves on the second welding line 20 .

[0057] It can be understood that, since both the first welding line 10 and the second welding line 20 extend along the first direction X, the routing direction N1 of the first welding line 10 and the routing direction N2 of the second welding line 20 are parallel to the first direction X.

[0058] “The first transfer mechanism 40 is used to drive the vehicle body to move from the second end 12 along the second direction Y to the third end 21” can be understood as the first transfer mechanism 40 is used to drive the vehicle body to move from the station of the first welding line 10 close to the second end 12 along the second direction Y to the station of the second welding line 20 close to the third end 21.

[0059] In the technical solution of this embodiment, along the first direction X, the third end 21 is aligned with the second end 12, so that the first transfer mechanism 40 can drive the car body to be transferred from the second end 12 to the third end 21 along the second direction Y through the shortest distance, thereby reducing the time required for the transfer by the first transfer mechanism 40, thereby optimizing the production rhythm of the white body welding production line 100.

[0060] According to some embodiments of the present application, referring to Figure 1 and Figure 2 The first transfer mechanism 40 includes a guide rail 40A and a first transfer platform 40B. The guide rail 40A extends along the second direction Y. The first transfer platform 40B is slidably disposed on the guide rail 40A and is used to grab the vehicle body.

[0061] It can be understood that a driving component is also provided on the first transfer platform 40B for driving the first transfer platform 40B to move along the guide rail 40A, and the driving component may be a driving motor.

[0062] Reference Figure 3 The first transfer platform 40B may include a dual-axis platform 40C and a gripper 40D. The dual-axis platform 40C is a platform formed by combining a linear module extending along a first direction X and a linear module extending along a second direction Y, wherein the dual-axis platforms 40C are arranged in two rows along the first direction X, and each row of dual-axis platforms 40C is arranged in the second direction Y. There are four grippers 40D connected to the four dual-axis platforms 40C, respectively. The four dual-axis platforms 40C are respectively used to drive the four grippers 40D to move along the first direction X and the second direction Y to fix the vehicle body relative to the first transfer platform 40B.

[0063] According to some embodiments of the present application, referring to Figure 1 and Figure 2The guide rail 40A has a first portion 41, and along the gravity direction Z, the first portion 41 is located above the first loading channel 30. When the first transfer platform 40B is located at the first portion 41, along the gravity direction Z, there is a gap between the first transfer platform 40B and the first loading channel 30 for materials to pass through.

[0064] Reference Figure 3 The first transfer platform 40B may include a first lifting mechanism 40E, the dual-axis platform 40C is connected to the first lifting mechanism 40E, and the first lifting mechanism 40E is used to drive the dual-axis platform 40C to reciprocate along the gravity direction Z. When the first transfer platform 40B is located at the first part 41, along the gravity direction Z, there is a gap between the first transfer platform 40B and the first loading channel 30 for the material to pass through.

[0065] The first lifting mechanism 40E may be a linear module or a hydraulic cylinder.

[0066] In the technical solution of this embodiment, along the gravity direction Z, there is a gap between the first transfer platform 40B and the first loading channel 30 for material to pass through, so that the material can enter the first loading channel 30 from one end of the first loading channel 30 close to the second end 12 of the first welding line 10 and the third end 21 of the second welding line 20, so that both ends of the first loading channel 30 in the first direction X can be used for material to enter the first loading channel 30, thereby improving the ability of the first loading channel 30 to provide materials.

[0067] According to some embodiments of the present application, referring to Figure 1 and Figure 4 The first welding line 10 includes a first conveyor line 10A and a plurality of first welding stations 10B. The first conveyor line 10A is used to drive the vehicle body to move from the first end 11 to the second end 12. The plurality of first welding stations 10B are arranged at intervals along the first conveyor line 10A. The second welding line 20 includes a second conveyor line 20A and a plurality of second welding stations 20B. The second conveyor line 20A is used to drive the vehicle body to move from the third end 21 to the fourth end 22. The plurality of second welding stations 20B are arranged at intervals along the second conveyor line 20A.

[0068] The first welding station 10B is a station in the first welding line 10 for processing the car body, and the first welding station 10B can be provided with a welding robot for welding; the second welding station 20B is a station in the second welding line 20 for processing the car body, and the second welding station 20B can be provided with a welding robot for welding.

[0069] The first conveyor line 10A is a conveyor line for driving the vehicle body to move along the routing direction N1 of the first welding line 10 , and the second conveyor line 20A is a conveyor line for driving the vehicle body to move along the routing direction N2 of the second welding line 20 .

[0070] In the technical solution of this embodiment, the car body is driven by the first conveyor line 10A, the first transfer platform 40B and the second conveyor line 20A and passes through the first end 11, the second end 12, the third end 21 and the fourth end 22 in sequence, thereby passing through multiple first welding stations 10B and multiple second welding stations 20B in sequence to complete the welding of the car body.

[0071] According to some embodiments of the present application, referring to Figure 4 The first conveyor line 10A and the second conveyor line 20A are both servo scissor fork conveyors.

[0072] The servo scissor fork conveyor is used to drive the vehicle body to move along the first direction X. The servo scissor fork conveyor is provided with a second lifting mechanism 10a. The second lifting mechanism 10a is used to drive the vehicle body to move along the gravity direction Z so as to make the vehicle body fit the positioning fixture on the welding station.

[0073] According to some embodiments of the present application, referring to Figure 1 The body-in-white welding production line 100 further includes a third welding line 50, a second feeding channel 60 and a second transfer mechanism 70. The third welding line 50 extends along the first direction X. The second welding line 20, the second feeding channel 60 and the third welding line 50 are arranged along the second direction Y, and the second feeding channel 60 is used to provide materials to the second welding line 20 and the third welding line 50. The second transfer mechanism 70 is used to drive the body to move between the second welding line 20 and the third welding line 50. In the second direction Y, the projection of the second welding line 20 and the projection of the third welding line 50 overlap.

[0074] The third welding line 50 constitutes part of the vehicle body line, and the first welding line 10, the second welding line 20 and the third welding line 50 can be used to complete one or more welding processes such as vehicle body bottom plate welding, vehicle body side panel welding, and vehicle body engine box welding. Exemplarily, the first welding line 10, the second welding line 20 and the third welding line 50 can be used for the above one process respectively, or the first welding line 10, the second welding line 20 and the third welding line 50 can jointly complete the above one process or multiple processes.

[0075] It can be understood that the third welding lines 50 are all set on the floor of the factory.

[0076] The second material supply channel 60 is a channel for supplying materials to the second welding line 20 and the third welding line 50 .

[0077] In some embodiments, the second loading channel 60 can be a conveyor belt.

[0078] In other embodiments, the second loading channel 60 may be a passage through which workers may provide shelves with materials to the second welding line 20 and the third welding line 50 .

[0079] The second transfer mechanism 70 is a mechanism for driving the vehicle body to move from the second welding line 20 to the third welding line 50 , that is, the second transfer mechanism 70 is used to connect the second welding line 20 and the third welding line 50 .

[0080] In the technical solution of this embodiment, along the second direction Y, the projection of the third welding line 50 overlaps with the projection of the second welding line 20 and the projection of the first welding line 10, thereby reducing the size of the body-in-white welding production line 100 in the first direction X, thereby reducing the requirements of the body-in-white welding production line 100 on the size of the site in the first direction X.

[0081] According to some embodiments of the present application, referring to Figure 1 , along the routing direction N3 of the third welding line 50, the third welding line 50 has a fifth end 51 and a sixth end 52 that are arranged opposite to each other, the routing direction N3 of the third welding line 50 is parallel to the first direction X, and along the first direction X, the fourth end 22 is aligned with the fifth end 51. The second transfer mechanism 70 is used to drive the vehicle body to move from the fourth end 22 to the fifth end 51 along the second direction Y.

[0082] The routing direction N3 of the third welding line 50 refers to the direction in which the vehicle body moves on the third welding line 50 .

[0083] It can be understood that, since the third welding line 50 extends along the first direction X, the routing direction N3 of the third welding line 50 is parallel to the first direction X.

[0084] “The second transfer mechanism 70 is used to drive the vehicle body to move from the fourth end 22 along the second direction Y to the fifth end 51” can be understood as the second transfer mechanism 70 is used to drive the vehicle body to move from the work station of the second welding line 20 close to the fourth end 22 along the second direction Y to the work station of the third welding line 50 close to the fifth end 51.

[0085] In the technical solution of this embodiment, along the first direction X, the fourth end 22 is aligned with the fifth end 51, so that the second transfer mechanism 70 can drive the car body to be transferred from the fourth end 22 to the fifth end 51 along the second direction Y through the shortest distance, thereby reducing the time required for the transfer by the second transfer mechanism 70, thereby optimizing the production rhythm of the white body welding production line 100.
