Description

Technical Field

[0001] The invention belongs to the field of body-in-white welding, and in particular relates to a flexible trial production line. Background Art

[0002] As society's demand for and attention to automobile products increases, the degree of automation of automobile body-in-white welding production lines also increases. As the automation of body-in-white welding production lines becomes increasingly mature, the automation requirements for the co-production of multiple models are also gradually increasing.

[0003] Usually, a new model will be pre-produced on a trial production line before mass production. However, in traditional trial production lines, most of the welding or assembly is done manually, the overall processing efficiency is low, and most of them adopt traditional rigid operation forms with low flexibility. In addition, traditional trial production lines often occupy a large area. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a flexible trial production line to solve the problems of low overall efficiency, low flexibility and large floor space of the trial production line in the prior art.

[0005] One solution of the present invention provides a flexible trial production line, comprising:

[0006] Tool library, used to store processing tools or processing parts;

[0007] A conveyor line for conveying traction components;

[0008] A traction component, used for traction or storage of processing tools and workpieces;

[0009] A processing assembly, used for processing a workpiece using a processing tool;

[0010] The tool magazine is arranged on the conveyor line, the traction assembly is movably connected to the conveyor line, and the processing assembly is located at one side of the conveyor line.

[0011] It should be noted that the traction assembly is externally connected to a driving device, which can control the traction assembly to move on the conveyor line. Although the tool magazine is installed on the conveyor line, a traction port is provided on the tool magazine for the conveyor line and the traction assembly to pass through. The traction assembly can move on the conveyor line and stop in the tool magazine to pull the corresponding processing tools in the tool magazine.

[0012] It should be noted that the traction component is provided with a traction piece for traction of processing tools or workpieces, and the processing tools and workpieces are provided with traction grooves adapted to the traction piece. The traction component achieves traction or storage of the processing tools or workpieces through the traction piece and the traction groove.

[0013] It should be additionally explained that the processing component may specifically be an automated processing equipment such as a robotic arm or a robot, and the processing component is provided with a corresponding structure for connecting a processing tool so as to connect and use the processing tool to complete the processing of the workpiece.

[0014] In this solution, the conveyor line can convey the traction component to the tool library, and use the traction component to realize the traction and storage of the processing tools or workpieces at the tool library, or convey the traction component to the processing component, and use the traction component to realize the switching of the processing tools at the processing component, or the traction and placement of the workpieces at the processing component;

[0015] In the actual use of this solution, a variety of processing tools with different uses and provided with traction grooves can be placed in the tool library to achieve the effect of multi-tool co-production;

[0016] Compared with the existing trial production lines, the present invention has a high degree of automation, and realizes automation from the loading and unloading of the workpiece, the switching of processing tools and the overall processing of the workpiece, eliminating the manual processing part and improving the overall processing efficiency; in addition, compared with the existing trial production lines, the present invention has higher flexibility, and the conveyor lines, traction components and processing components in the present invention can all choose the corresponding installation positions and installation quantities according to actual production needs; in addition, compared with the existing trial production lines, the present invention occupies a relatively small area, the overall structure of the present invention is simple, and on the basis of high flexibility, the installation position and installation quantity of the tool library, conveyor lines, traction components and processing components in the present invention can be controlled according to the actual size of the space used to place the present invention, so as to control the floor space of the present invention.

[0017] In one of the solutions, the conveyor line is further provided with a processing station and an upper and lower piece station, wherein the processing station is used for processing the workpiece, and the upper and lower piece station is used for processing the upper and lower pieces of the workpiece.

[0018] It should be noted that an automatic loading and unloading device for automatic loading is arranged outside the loading and unloading station to cooperate with the loading and unloading station to realize automatic loading and unloading of the processed parts.

[0019] In one embodiment, the processing assembly is installed on one side of the processing station.

[0020] It should be noted that the processing component is specifically a robotic arm, and the robotic arm is provided with a corresponding structure for connecting a processing tool so as to grab and use the processing tool to complete the processing of the workpiece; in the actual processing process of the present invention, the conveyor line first transports the workpiece to be processed and the processing tools required for processing the workpiece to the processing station through the traction component, and the robotic arm is then connected to the processing tool through the corresponding structure, and starts to process the workpiece to be processed at the processing station. After the processing is completed, the robotic arm can choose to put the processing tool back to the processing station according to the settings, so that the traction component can transport it back to its original position and unload the processed workpiece, or retain the processing tool and use it to process the next workpiece to be processed that is transported to the processing station.

[0021] In this solution, by setting up processing stations and loading and unloading stations, and coordinating the conveyor line, tool library, traction assembly and processing assembly, it is possible to realize the loading of workpieces to be processed and the unloading of completed workpieces, and at the same time complete the switching of processing tools. Compared with the existing trial production line, this solution has the characteristics of high degree of automation and high processing efficiency.

[0022] In one of the solutions, a conveying trolley is also installed on the conveying line, and the traction assembly is installed on the conveying trolley.

[0023] In one of the schemes, the traction assembly includes a sliding guide rail and a traction unit, the sliding guide rail is installed on the conveying trolley, the traction unit is movably connected to the sliding guide rail, and the traction unit is provided with a traction member for traction of the processing tool.

[0024] In one embodiment, the traction assembly further comprises a traction track mounted on the conveying trolley, and the traction track is used to pull the traction unit to slide on the sliding guide rail.

[0025] It should be noted that the conveying trolley is externally connected to a conveying drive system for driving the conveying trolley, and the conveying trolley is used to convey the traction assembly to any position on the conveying line.

[0026] It should be additionally explained that more than one traction assembly can be set on the conveying cart. Correspondingly, the number and structure of the storage locations in the tool library, the number and structure of the processing stations, and the number and structure of the upper and lower pieces stations are all changed synchronously with the setting of the corresponding traction assembly, so as to synchronously pull multiple tools from the tool library and synchronously transport them to multiple processing stations, or synchronously pull multiple workpieces to be processed from multiple upper and lower pieces stations to multiple processing stations, or synchronously pull multiple completed workpieces from the processing stations to multiple upper and lower pieces stations, etc.

[0027] In this solution, by providing a conveying trolley, the flexibility of the present invention can be increased to meet the target requirements of the trial production line to a greater extent.

[0028] In one embodiment, the tool library includes a plurality of storage locations, in which processing tools are placed.

[0029] In one embodiment, the processing tool and the processing workpiece are both provided with a traction groove for connecting the traction assembly.

[0030] It should be noted that the traction groove is adapted to the traction piece, and the processing tool and the processing piece are connected to the traction assembly through the cooperation between the traction groove and the traction piece.

[0031] In one of the schemes, the tool library includes a first storage library and a second storage library, the conveyor line passes between the first storage library and the second storage library, and a lifting mechanism is provided between the first storage library and the second storage library.

[0032] It should be noted that the lifting mechanism can lift the transport trolley located between the first storage warehouse and the second storage warehouse to the corresponding storage location, so that the traction component on the transport trolley can slide the processing tool or the workpiece to the corresponding storage location.

[0033] In this solution, users can classify the storage locations of processing tools and workpieces through the first storage warehouse and the second storage warehouse according to actual needs. For example, the first storage warehouse is used to store processing tools, and the second storage warehouse is used to store workpieces to be processed and completed workpieces.

[0034] In one embodiment, the first storage warehouse and the second storage warehouse each include a plurality of storage locations.

[0035] It should be noted that the multiple storage locations in the first storage warehouse and the second storage warehouse are all arranged vertically.

[0036] It should be noted that the size of the storage location can also be set according to the user's own needs, so that processing tools or workpieces of different sizes can be placed at the same time.

[0037] In this solution, multiple storage locations in the first storage library and the second storage library are arranged vertically, so that the number of tool library locations can be increased without increasing the floor space of the tool library itself, and the traction component can normally pull the processing tools in the tool library through cooperation with the traction component.
