[0001] This utility model relates to the field of forklift manufacturing and processing technology, specifically to an automated production line for processing upright plates and roller shafts. Background Technology

[0002] The fork carriage is the main load-bearing component of a forklift. It is mounted in the mast of the forklift via roller axles and moves up and down. Welding the upright plate to the roller axles is a process in the production of the fork carriage. The welded parts are the main components of the fork carriage. The upright plate and roller axles are pre-assembled and welded, and finally assembled into the fork carriage as welded structural parts.

[0003] In the production process of column plates and roller shafts, the assembly process requires one operator, and after assembly, the semi-finished parts are stacked and stored in a designated location before being moved to the next process. Similarly, the welding process requires another operator, and after welding, the semi-finished parts are stacked and stored in a designated location before being moved to the next process. It is evident that the existing production process requires multiple operators and a large area for storing semi-finished parts, resulting in a large required space and a large number of operators, thus increasing production and labor costs. Utility Model Content

This automated production line can realize automated welding of column plates and roller shafts and automatic material flow between processes, reducing the intensity of manual operation and saving labor costs.

[0005] To achieve the above objectives, this utility model provides an automated processing production line for column plates and roller shafts. This automated processing production line includes a loading power trolley, a gantry robot, a transfer logistics conveyor line, an automatic positioning welding fixture, a shaft head conveyor line, a handling robot, an automated welding robot, and a power conveyor line; wherein...

[0006] The loading trolley is used to load column plates and transport them to the gantry robot. The gantry robot picks up the column plates and places them on the transfer logistics conveyor line. The transfer logistics conveyor line is used to transport the column plates to the automatic positioning welding fixture, which is used to position the column plates. The shaft head conveyor line is used to load roller shafts and transport them to the handling robot. The handling robot picks up the roller shafts, places them in the corresponding positions on the column plates, and then presses them down for positioning. The automated welding robot is used to weld the column plates and roller shafts. The power conveyor line is used for unloading after welding is completed.

[0007] Preferably, the gantry robot includes a suction arm, which is configured to simultaneously pick up a pair of symmetrical column plates located on the loading power trolley and place them on the transfer logistics conveyor line.

[0008] Preferably, the transfer logistics conveyor line is equipped with a guiding device, which is used to guide a pair of column plates into the automatic positioning welding fixture.

[0009] Preferably, the guiding device includes two sets of guide plates symmetrically arranged on the transfer material conveyor line, and each pair of guide plates has a flared opening at one end facing the material feeding direction of the column plate.

[0010] Preferably, the automatic positioning welding fixture includes a blocking mechanism located at the front end of the welding process and a positioning mechanism set on the automatic lifting mechanism. The positioning mechanism includes a clamping mechanism and is configured such that when the blocking mechanism contacts the column plate, the automatic lifting mechanism drives the positioning mechanism to start the positioning operation.

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0029] In this utility model, unless otherwise stated, directional words such as "upper" and "lower" included in the terminology only represent the orientation of the term in its normal use state, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0030] See Figure 1 and Figure 2 This utility model provides an automated production line for processing column plates and roller shafts. The automated production line includes a loading power trolley 6, a gantry robot 7, a transfer logistics conveyor line 1, an automatic positioning welding fixture 3, a shaft head conveyor line 4, a handling robot 5, an automated welding robot 2, and a power conveyor line; wherein,

[0031] The loading trolley 6 is used to load column plates and transport them to the gantry robot 7. The gantry robot 7 is used to pick up the column plates and place them on the transfer logistics conveyor line 1. The transfer logistics conveyor line 1 is used to transport the column plates to the automatic positioning welding fixture 3. The automatic positioning welding fixture 3 is used to position the column plates. The shaft head conveyor line 4 is used to load roller shafts and transport them to the handling robot 5. The handling robot 5 is used to grab the roller shafts and place them in the corresponding positions on the column plates before pressing them down for positioning. The automated welding robot 2 is used to weld the column plates and roller shafts. The power conveyor line is used for unloading after welding is completed.

[0032] According to the above technical solution, a loading trolley 6 is used to load the column plates and transport them to the operating area of ​​the gantry robot 7. The gantry robot 7 picks up the column plates and places them on the transfer conveyor line 1, which then transports them to the automatic positioning welding fixture 3 for positioning. The automatic positioning welding fixture 3 positions the column plates. Meanwhile, the shaft conveyor line 4 loads the roller shafts and transports them to the operating area of ​​the handling robot 5. The handling robot 5 picks up the roller shafts, places them in the corresponding positions on the column plates, and presses them down for positioning. At this point, the automated welding robot 2 is activated to weld and fix the column plates and roller shafts. Finally, the finished welded product is discharged from the power conveyor line. The entire process automates the loading and unloading of column plates and roller shafts, the positioning and assembly, and the welding and fixing, resulting in improved production efficiency, enhanced operational safety, and reduced labor intensity.

[0033] like Figure 3As shown, in this embodiment, the gantry robot 7 includes a suction arm 71, which is configured to simultaneously pick up a pair of symmetrical column plates located on the loading power trolley 6 and place them on the transfer material conveyor line 1. Thus, in the first step of the automated production line for column plates and roller shafts, the column plates are unstacked and loaded. Specifically, the loading power trolley 6 transports a stack of column plates to be loaded to below the gantry robot 7, and the suction arms 71 of the gantry robot 7 pick up the column plates (one on each side) and place them on the transfer material conveyor line 1. The power conveyor line then transports the column plates to the welding fixture in the welding process.

[0034] like Figure 4 As shown, in this embodiment, a guide device 11 is provided on the transfer material conveyor line 1. The guide device 11 is used to guide a pair of column plates into the automatic positioning welding fixture 3 respectively.

[0035] Furthermore, in one specific embodiment, the preferred guiding device 11 includes two sets of guide plates symmetrically arranged on the transfer material conveying line 1, and each pair of guide plates has a flared opening at one end facing the material feeding direction of the column plate.

[0036] Furthermore, in this embodiment, an automatic positioning welding fixture 3 (see...) is preferred. Figure 5 The system includes a blocking mechanism located at the front end of the welding process and a positioning mechanism set on the automatic lifting mechanism. The positioning mechanism includes a clamping mechanism and is configured such that when the blocking mechanism contacts the column plate, the automatic lifting mechanism drives the positioning mechanism to start the positioning operation. When the column plate reaches the preset position, the automatic lifting mechanism drives it to rise, and the clamping mechanism performs lateral positioning of the column plate.

[0037] Thus, in the second step of the automated production line for column plates and roller shafts, the column plates are fed and positioned. Specifically, one column plate on each side is symmetrical and can be automatically transferred through the transfer material conveyor line 1. The conveyor line has a guiding device 11 to accurately guide the material to the welding process. A blocking mechanism is provided at the front end of the welding process. When the blocking mechanism contacts the column plate, the positioning mechanism installed in a set of automatic lifting mechanisms starts to work. After the column plate is in place, the lifting mechanism rises, and the clamping mechanism in the positioning mechanism is activated to achieve the lateral positioning of the column plate.

[0038] like Figure 6 As shown, in this embodiment, the shaft head conveyor line 4 is a chain plate conveyor line and is connected to the shaft head hopper to store and feed roller shafts.

[0039] Furthermore, it is preferable to provide a proximity switch at the gripping position of the handling robot 5. The proximity switch is configured to stop the shaft head conveyor line 4 when the roller shaft reaches the predetermined position and restart the shaft head conveyor line 4 to convey forward after the handling robot 5 grips it.

[0040] Thus, in the third step of the automated production line for the column plate and roller shafts, the roller shafts are loaded and positioned. Specifically, the shaft head hopper uses a chain conveyor line to load and store the roller shafts, which can meet the needs of centralized loading of a certain number of roller shafts and material handling by the handling robot. A proximity switch is installed at the robot's gripping position. When the roller shaft reaches the position, the conveyor line automatically stops; when there is no roller shaft at the robot's gripping position, the conveyor line automatically moves forward. The handling robot then grips the roller shaft, places it in the corresponding position on the column plate, and presses it down for positioning.

[0041] In this embodiment, it is preferred that the automated welding robot 2 cooperates with the handling robot 5 and is configured such that after the automated welding robot 2 uniformly spot welds the positioned roller shaft, the handling robot 5 withdraws from the welding area and the automated welding robot 2 completes all the welds of the component after spot welding.

[0042] Thus, in the fourth step of the automated production line for the column plate and roller shaft, spot welding, welding, and unloading take place. Specifically, the automated welding robot 2 evenly spot welds the positioned roller shaft, then the transport robot 5 moves it out of the welding station, and the automated welding robot 2 completes all the welds on the component after spot welding. After completion, the power conveyor line operates to transport the finished product (such as...) Figure 7 (As shown) the material is discharged.

[0043] In summary, the process involves the following four steps:

[0044] First, the column plates are unstacked and loaded. The loading power trolley 6 transports a stack of column plates to be loaded to the bottom of the truss robot 7. The suction arms 71 of the truss robot 7 pick up the column plates (one on each side) and place them on the transfer logistics conveyor line 1. The power conveyor line runs and transports the column plates to the welding fixture of the welding process.

[0045] Secondly, the column plates are fed and positioned. The column plates, one on each side, can be automatically transferred through the transfer material conveyor line 1. The conveyor line has a guiding device 11 to accurately guide the material to the welding process. A blocking mechanism is provided at the front end of the welding process. When the blocking mechanism contacts the column plate, the positioning mechanism installed in a set of automatic lifting mechanisms starts to work. When the column plate is in place, the lifting mechanism rises, and the clamping mechanism in the positioning mechanism is activated to achieve the lateral positioning of the column plate.

[0046] Next, the roller shafts are loaded and positioned. The shaft head hopper uses a chain conveyor line to load and store the roller shafts, which can meet the needs of centralized loading of a certain number of roller shafts and material handling by the handling robot. A proximity switch is installed at the robot's gripping position. When the roller shaft reaches the position, the conveyor line automatically stops; when there is no roller shaft at the robot's gripping position, the conveyor line automatically moves forward. The handling robot then grips the roller shaft, places it in the corresponding position on the column plate, and presses it down for positioning.

[0047] Finally, spot welding, general welding, and unloading are performed. The automated welding robot 2 evenly spot welds the positioned roller shaft, and then the transport robot 5 moves it out of the welding station. The automated welding robot 2 then completes all the welds on the spot-welded component. After completion, the power conveyor line operates to unload the finished product.

[0048] Ultimately, it achieved automation of loading and unloading of column plates and roller shafts, automation of positioning and assembly, and automation of welding and fixing, which has the effects of improving production efficiency, improving operational safety, and reducing labor intensity.

[0049] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
