Description

TECHNICAL FIELD

[0001] The utility model relates to industrial technology field, concretely relates to a welding workstation. BACKGROUND

[0002] In some traditional welding operation environment, the workpiece feeding and discharging operation is relied on manual work. This way not only leads to significant increase in labor intensity, but also has certain safety hazards. In addition, the manual feeding and discharging mode also has the problem of low work efficiency. Since each workpiece must wait for the previous workpiece to complete welding before being discharged by manual work and then a new workpiece to be welded is loaded, this process inevitably causes waste of time, thereby limiting the overall production efficiency of the welding workstation, which cannot meet the demand of modern manufacturing industry for efficient and automated production process.

[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] The following is for reference. Figures 1-6 Describes a welding workstation 100 according to an embodiment of the present utility model.

[0043] like Figure 1As shown, the welding workstation 100 according to an embodiment of the present utility model includes a loading area 1, a welding area 2 and an unloading area 3 arranged sequentially along the material conveying direction.

[0044] Here, the loading area 1 can automatically load the workpieces to be welded, improving the level of automation in the operation.

[0045] Welding zone 2 is used for automated welding operations, improving welding efficiency and product quality consistency.

[0046] The unloading area 3 is used to unload the welded workpieces so that they can proceed to the next stage.

[0047] By setting up multiple functional zones arranged in an orderly manner along the direction of material flow, the overall layout of the welding workstation 100 is made more scientific and reasonable, further improving welding efficiency.

[0048] Combination Figure 1 and Figure 2 The welding workstation 100 also includes at least two guide rail mechanisms 40.

[0049] Each guide rail mechanism 40 extends along the material conveying direction. The guide rail mechanism 40 provides a stable and efficient running path for the movement of the workpiece to be welded.

[0050] In some alternative embodiments, the guide rail mechanism 40 may be a straight extension or an extension of a curve, a broken line, or other shapes to accommodate different layouts.

[0051] Each guide rail mechanism 40 is equipped with a reciprocating welding fixture 61.

[0052] The welding fixture 61 is used to support and position the workpiece to be welded. The welding fixture 61 moves along the guide rail mechanism 40, thereby moving the workpiece to be welded along with it.

[0053] Here, the welding fixture 61 is used to initially clamp or fix the workpiece to be welded, ensuring that the workpiece will not be displaced during subsequent movement.

[0054] Therefore, in some alternative embodiments, the welding fixture 61 may include a clamp, a magnetic fixing device, or other positioning device. This fixes the workpiece to be welded in a preset position, ensuring the accuracy of the weld joint and improving welding reliability.

[0055] Each welding fixture 61 enters the loading area 1, welding area 2 and unloading area 3 in sequence.

[0056] The automation capability of the welding workstation 100 can be improved by moving the welding fixture 61. The welding fixture 61 moves the workpiece to be welded to the welding area 2, reducing manual intervention and improving welding efficiency.

[0057] Specifically, the welding fixture 61 carries the workpiece to be welded from the loading area 1 into the welding area 2, and after welding is completed, it enters the unloading area 3 from the welding area 2.

[0058] It is worth noting that in some traditional welding processes, the workpiece may need to be transferred from one platform to another (e.g., from the loading platform to the welding platform, and then to the unloading platform). This multiple transfer process can easily lead to problems such as workpiece collisions, deformation, or positioning deviations. However, the welding workstation 100 in this embodiment utilizes the welding fixture 61 to support the workpiece throughout the entire process, effectively avoiding these risks. Throughout the process, the workpiece remains fixed on the same welding fixture 61, eliminating the need for re-clamping or position adjustment. This not only reduces the cumulative error caused by multiple clamping operations but also ensures the consistency of the workpiece's posture before and after welding, thereby improving welding quality. Simultaneously, since no additional time is needed for workpiece transfer and repositioning, the entire welding process production cycle is shortened, thus improving overall production efficiency.

[0059] When one welding fixture 61 is located in unloading area 3, the other welding fixture 61 is located in welding area 2.

[0060] The welding workstation 100 is equipped with at least two welding fixtures 61 to enable alternating operations.

[0061] While one of the welding fixtures 61 is in the unloading area 3 to remove the finished workpiece, the other welding fixture 61 is in the welding area 2 to perform the welding task.

[0062] In some alternative embodiments, the welding fixture 61 that has completed unloading in the unloading area 3 directly enters the loading area 1 to load new workpieces to be welded.

[0063] This alternating operation method makes full use of the space and time resources of the welding workstation 100, allowing each welding fixture 61 to quickly move to the next process after completing the current process, without being idle while waiting for other processes to complete.

[0064] The welding workstation 100 of this embodiment of the utility model also includes a loading mechanism 10. The loading mechanism 10 is located in the loading area 1 and is used to move the workpiece to be welded onto the welding fixture 61.

[0065] The automated operation of the feeding mechanism 10 can reduce manual intervention and achieve a seamless connection from the storage of workpieces to be welded to the loading of the welding fixture 61, thereby improving production efficiency.

[0066] In some alternative embodiments, the feeding mechanism 10 includes a power drive system. The power drive system may be a servo motor, cylinder, or hydraulic system, etc., for providing precise motion control.

[0067] In some alternative embodiments, the feeding mechanism 10 may include a robotic arm, a suction cup, or a gripper 3122.

[0068] Optionally, the feeding mechanism 10 may also include a vision recognition system or sensors, etc., for detecting the position and orientation of the workpiece to be welded, which helps to adjust the gripping action to ensure accurate placement.

[0069] The welding workstation 100 of this embodiment of the utility model also includes a welding mechanism 20. For example... Figure 2 As shown, the welding mechanism 20 is located in the welding area 2 and is used to weld the workpieces to be welded on the welding fixture 61 to form a welded workpiece 201. The welding mechanism 20 includes a first welding tool 21, which is used to alternately weld the workpieces to be welded on different guide rail mechanisms 40.

[0070] By setting the first welding tool 21, efficient welding at multiple stations can be achieved. Specifically, the first welding tool 21 welds the workpiece to be welded on one guide rail mechanism 40, and after welding is completed, it quickly switches to another workpiece to be welded on another guide rail mechanism 40 to continue welding.

[0071] Optionally, the welding mechanism 20 includes a robotic arm, a linear module and rotary axis assembly, a gantry 311 structure, and other moving devices. The moving devices are used to drive the first welding tool 21 to alternately approach the workpieces to be welded located on different guide rail mechanisms 40, ensuring the continuity and efficiency of the welding process.

[0072] When the welding mechanism 20 includes a robotic arm, the advantages of the robotic arm's multiple degrees of freedom are utilized to achieve more complex spatial movements, meeting the needs of various welding paths and angles.

[0073] When the welding mechanism 20 includes a combination of a linear module and a rotary axis, it can realize the spatial movement function of the first welding tool 21. At the same time, this combination structure is simple and has a low cost.

[0074] When the welding mechanism 20 includes the gantry frame 311 structure, the first welding tool 21 is mounted on the crossbeam, and spatial positioning is achieved through the horizontal movement of the crossbeam and the vertical movement of the column. This gantry frame 311 structure has strong load-bearing capacity and is suitable for welding large workpieces.

[0075] like Figure 2 and Figure 3 As shown, the welding workstation 100 of this embodiment of the present invention also includes an unloading mechanism 31. The unloading mechanism 31 is located in the unloading area 3 and is used to unload the welded workpieces 201 from at least two welding fixtures 61.

[0076] The automated operation of the unloading mechanism 31 can reduce manual intervention and achieve efficient transfer of the welded workpiece 201 from the welding fixture 61 to subsequent processes.

[0077] In some alternative embodiments, the unloading mechanism 31 includes a gripping device. The gripping device may be a robotic arm, a suction cup, or a clamp 3122, etc. The gripping device is used to remove the welded workpiece 201 from the welding fixture 61. These gripping devices can be selected according to the shape, material, and weight of the workpiece, and this application is not limited thereto.

[0078] Optionally, the unloading mechanism 31 also includes a drive unit. Here, the drive unit can be driven by a servo motor, cylinder, or hydraulic system. The drive unit controls the spatial movement of the gripping device, so that the welded workpiece 201 can be accurately removed and placed in a predetermined position.

[0079] The welding workstation 100 of this embodiment integrates automated loading and unloading functions, effectively reducing the need for manual operation. Furthermore, the welding workstation 100 achieves full-process automation from loading to welding to unloading, with close coordination between each process, enabling continuous production without manual intervention, further improving production efficiency and consistency.

[0080] According to some optional embodiments of the present invention, see [reference]. Figure 2 At least one first welding tool 21 is provided between each pair of adjacent guide rail mechanisms 40, and the first welding tool 21 can rotate between the two guide rail mechanisms 40.

[0081] In the above technical solution, the first welding tool 21 rotates between two adjacent guide rail mechanisms 40, and uses its flexible switching capability to provide welding services for workpieces to be welded located on different guide rails.

[0082] This layout avoids the need for separate welding tools for each guide rail mechanism 40, which helps reduce the number of devices and cost.

[0083] Meanwhile, the rotatable function of the first welding tool 21 allows it to quickly switch between the two guide rail mechanisms 40, ensuring the continuity and efficiency of the welding process. For example, after completing the welding of a workpiece on one guide rail, the first welding tool 21 can quickly adjust its angle or position to begin welding the workpiece on another guide rail.

[0084] In some alternative embodiments, the welding mechanism 20 includes a rotary joint, to which the first welding tool 21 is connected. It is worth noting that the rotary joint is capable of angular adjustment and continuous rotation around a specific axis. This allows the first welding tool 21 to flexibly switch between two adjacent guide rail mechanisms 40, adapting to the welding requirements of different workpieces.

[0085] Optionally, the welding mechanism 20 also includes a speed reducer. By providing a speed reducer, the stability of the first welding tool 21 during rotation is improved.

[0086] In some specific embodiments, such as Figure 2 As shown, there are two guide rail mechanisms 40 arranged in parallel. The welding mechanism 20 also includes a second welding tool 22, which is provided on the side of each guide rail mechanism 40 away from the other guide rail mechanism 40.

[0087] The two guide rail mechanisms 40 are arranged in parallel, allowing the welding fixture 61 to move independently along its respective guide rail without interfering with each other. This not only facilitates the management of the workpiece's flow path but also ensures smooth switching of the welding fixture 61 between the loading area 1, the welding area 2, and the unloading area 3.

[0088] A second welding tool 22 is provided on the side of each guide rail mechanism 40 away from the other guide rail mechanism 40. This means that the second welding tool 22 is located on the outside of the guide rail mechanism 40, rather than between the two guide rails.

[0089] Here, placing the second welding tool 22 on the outside of the two guide rail mechanisms 40 can effectively prevent it from colliding or interfering with the first welding tool 21 or other components, thereby providing the second welding tool 22 with a certain operating space so that it can perform welding tasks at multiple angles, such as edge welds or welding at special angles.

[0090] By setting a second welding tool 22 on the outside of each guide rail mechanism 40, the welding workstation 100 can perform additional welding operations simultaneously without affecting the operation of the first welding tool 21, thereby further improving overall production efficiency.

[0091] Optionally, the first welding tool 21 and the second welding tool 22 may include the same welding head or different welding heads. This allows for flexible adjustment of the functions of the welding workstation 100 to achieve optimal production results.

[0092] In some technical solutions, the first welding tool 21 and the second welding tool 22 use the same welding head, for example, both using an electric welding gun or a laser welding head. This simplifies equipment configuration and maintenance processes. Furthermore, using the same welding head facilitates unified management of consumables and spare parts, reducing inventory complexity.

[0093] In other technical solutions, the first welding tool 21 and the second welding tool 22 employ different welding heads. For example, the first welding tool 21 uses an electric welding gun, while the second welding tool 22 uses a laser welding head. This combination leverages the advantages of different types of welding heads. By combining the two, the welding workstation 100 can simultaneously meet the needs of roughing and finishing, thereby improving overall welding quality and efficiency. For example, in some welding processes, the first welding tool 21 can complete the connection of the main structure, while the second welding tool 22 is responsible for sealing the fine edges.

[0094] In some such Figure 1 In the illustrated embodiment, the welding workstation 100 also includes a protective canopy 24 and a dust collector 26. The protective canopy 24 covers the welding area 2, and the dust collector 26 is used to collect fumes and dust generated during the welding process to improve the working environment for production personnel. Simultaneously, the work area enclosed by the protective canopy 24 also protects production personnel from mechanical injuries.

[0095] Optionally, such as Figure 1 As shown, the welding workstation 100 also includes a control cabinet 27, which is located in the welding area 2 and is used to control at least one of the first welding tool 21 and the second welding tool 22. The control cabinet 27 also includes a power supply for welding.

[0096] According to some optional embodiments of the present invention, combined with Figures 1-2 and Figure 4 The welding workstation 100 also includes a positioner 50, which is movably mounted on the guide rail mechanism 40.

[0097] The positioner 50 is used to carry the welding fixture 61 and moves the welding fixture 61 along the guide rail mechanism 40 to a preset position by its own movement. For example, in an automated welding process, the positioner 50 can drive the welding fixture 61 through the loading area 1, the welding area 2 and the unloading area 3 in sequence, thereby realizing the full process processing of the workpiece.

[0098] The welding fixture 61 is rotatably connected to the positioner 50. This configuration gives the welding fixture 61 multi-directional rotation capability. In this embodiment, the rotation direction of the welding fixture 61 is not restricted. Thus, during actual welding, the welding fixture 61 can flexibly adjust the posture and angle of the workpiece as needed, providing the welding torch with more welding position options. For example, when welding complex curved surfaces or irregularly shaped workpieces, the welding fixture 61 can rotate any surface or edge of the workpiece to the optimal position accessible to the welding torch through rotational positioning, thereby avoiding welding blind spots caused by workpiece posture limitations. Furthermore, this unrestricted rotation capability can also optimize the welding path, reduce the welding torch's movement range, and improve welding efficiency.

[0099] In some specific embodiments, such as Figure 4 As shown, the positioner 50 includes two support bases 51 and two flanges 52. The two support bases 51 are arranged at intervals and are movably mounted on the guide rail mechanism 40. The two flanges 52 are located between the two support bases 51 and are respectively connected to the two support bases 51. The flanges 52 are rotatable relative to the support bases 51. A welding fixture 61 is connected between the two flanges 52.

[0100] The distance between the two support seats 51 can be adjusted according to actual needs. By adjusting the spacing of the support seats 51, the positioner 50 can adapt to diverse welding tasks ranging from small to large parts, thereby improving the applicability and flexibility of the equipment. In addition, two flanges 52 are respectively mounted on the support seats 51, and the welding fixture 61 is connected between the two flanges 52. With the rotation capability of the flanges 52, the welding fixture 61 can achieve multi-angle rotation and flexibly adjust the workpiece posture.

[0101] This configuration not only ensures the stability of the welding fixture 61, but also gives it a high degree of flexibility, enabling it to meet the multi-directional welding needs of complex workpieces and improve the versatility and adaptability of the positioner 50.

[0102] In some alternative embodiments, such as Figure 4 As shown, two support seats 51 are spaced apart along the material conveying direction. In the above technical solution, the support seats 51 arranged along the material conveying direction can better match the direction of the guide rail mechanism 40. When the spacing of the support seats 51 is adjusted to accommodate workpieces of different sizes, since their arrangement direction is parallel to the guide rail, they will not interfere with other components, ensuring the stability of the structure and the flexibility of operation.

[0103] The positioner 50 also includes a base frame 53, which is slidably mounted on the guide rail mechanism 40, and two support seats 51 are provided on the base frame 53.

[0104] The base frame 53 supports the two support seats 51, ensuring the stability and consistency of the two support seats 51. By slidably mounting the base frame 53 onto the guide rail mechanism 40, the positioner 50 can move smoothly along the guide rail, driving the welding fixture 61 and the workpiece to flow between the loading area 1, the welding area 2, and the unloading area 3.

[0105] Optionally, the base frame 53 extends along the material conveying direction. This facilitates the adjustment of the position of the support base 51.

[0106] In some optional embodiments, a slider 56 is further provided between the base frame 53 and the guide rail mechanism 40. Specifically, the slider 56 is mounted on the bottom of the base frame 53, and the guide rail mechanism 40 includes a linear guide rail, so that smooth sliding is achieved by the cooperation of the slider 56 and the guide rail. Alternatively, a linear ball bearing is included between the base frame 53 and the guide rail mechanism 40.

[0107] The sliding structure between the base frame 53 and the guide rail mechanism 40 in this application can adopt a known solution in the prior art. The sliding structure itself is not the core point of the solution in this application, so it will not be described in detail here.

[0108] In some specific embodiments, combined with Figure 4 The positioner 50 also includes a first drive mechanism 54, which is mounted on the base frame 53 and cooperates with the guide rail mechanism 40 to drive the base frame 53 to move relative to the guide rail mechanism 40.

[0109] The first drive mechanism 54 provides power to drive the base frame 53 to slide along the guide rail mechanism 40. This achieves automated movement of the base frame 53, reduces manual intervention, and improves production efficiency.

[0110] Optionally, the first drive mechanism 54 can be a servo motor or a stepper motor, which converts rotary motion into linear motion through a lead screw or synchronous belt drive, thereby pushing the base frame 53 to slide along the guide rail to realize the automation of the positioner 50.

[0111] The first drive mechanism 54 is mounted on the base frame 53, which also prevents interference with other components. This layout ensures that the first drive mechanism 54 can operate independently without affecting the normal function of the guide rail mechanism 40 or the support base 51. At the same time, the base frame 53 provides a stable mounting foundation for the first drive mechanism 54, making it more stable and reliable when moving the base frame 53. In addition, this arrangement also optimizes the spatial layout to a certain extent, helping to improve the compactness of welding operations.

[0112] More specifically, such as Figure 4 As shown, the positioner 50 further includes a second drive mechanism 55. The second drive mechanism 55 is mounted on the support base 51 and cooperates with at least one flange 52 to drive the flange 52 to rotate.

[0113] Here, the second drive mechanism 55 acts directly on the flange 52, ensuring the accuracy and stability of the rotational motion and avoiding additional energy loss. Secondly, since the second drive mechanism 55 is mounted on the support base 51, it is independent of the base frame 53 and other components, preventing interference and making the layout of the positioner 50 more compact and rational. Furthermore, the second drive mechanism 55 can adjust the rotational speed and direction of the flange 52 according to actual needs, adapting to the welding process requirements of different workpieces.

[0114] For example, in the welding of complex curved workpieces, the second drive mechanism 55 is activated, and by controlling the rotation angle of the flange 52, the workpiece is adjusted to the optimal welding position, thereby improving welding quality and efficiency, and enhancing the flexibility and intelligence of the positioner 50.

[0115] In some specific embodiments, such as Figure 1 As shown, the guide rail mechanism 40 includes a slide rail 41 and a rack 43, which extend along the material conveying direction. The slide rail 41 supports and guides the base frame 53 of the positioner 50 to move smoothly, ensuring its operation without deviation. The rack 43 cooperates with the gear in the drive mechanism to provide precise linear motion power transmission to the base frame 53.

[0116] See Figure 4 The positioner 50 also includes a slider 56 mounted on the base frame 53, which slides in cooperation with the slide rail 41.

[0117] The slider 56 is mounted on the base frame 53 and forms a sliding engagement with the slide rail 41 in the guide rail mechanism 40, which serves to support and guide.

[0118] Optionally, the slider 56 and slide rail 41 may be made of low-friction materials or rolling elements. This helps to reduce running resistance and wear. Simultaneously, it helps to improve the motion accuracy of the positioner 50 and increase production efficiency.

[0119] Please see Figure 4 The first drive mechanism 54 further includes: a first drive motor 542 mounted on the base frame 53, and a first drive gear 544 connected to the first drive motor 542, wherein the first drive gear 544 meshes with the rack 43.

[0120] The first drive mechanism 54, through the cooperation of the first drive motor 542 and the first drive gear 544, enables the precise movement of the base frame 53 along the guide rail mechanism 40. Specifically, the first drive motor 542 is mounted on the base frame 53, providing power output, which is transmitted to the first drive gear 544, causing the gear to mesh with the rack 43 on the guide rail mechanism 40. This design converts the rotational motion of the first drive motor 542 into the linear motion of the base frame 53, ensuring smooth, precise, and controllable movement.

[0121] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 2 The feeding area 1 includes a cantilever crane 11 corresponding to each guide rail mechanism 40.

[0122] Since each guide rail mechanism 40 is equipped with an independent cantilever crane 11, multiple welding fixtures 61 can be fed at the same time, avoiding mutual interference and thus improving the production cycle.

[0123] In some alternative embodiments, the cantilever crane 11 includes a rotatable and telescopic boom. The boom enables precise grabbing of workpieces to be welded from a storage area or conveyor belt and placing them onto the corresponding welding fixture 61.

[0124] Combination Figure 1 and Figure 2 When there are two guide rail mechanisms 40, the loading area 1 is equipped with two cantilever cranes 11. Each cantilever crane 11 serves one guide rail mechanism 40 and is responsible for accurately placing the workpiece onto the corresponding welding fixture 61, ensuring that the loading process is efficient and does not interfere with each other.

[0125] According to some optional embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the unloading mechanism 31 also includes a gantry frame 311 and an unloading fixture 312. The gantry frame 311 is located in the unloading area 3 and spans all the guide rail mechanisms 40. The unloading fixture 312 is movably mounted on the gantry frame 311 and is used to alternately clamp and remove the welded workpieces 201 on the guide rail mechanisms 40.

[0126] Here, the gantry 311 is located in the unloading area 3 and spans all guide rail mechanisms 40, forming a stable support structure. This layout allows the unloading fixture 312 to move freely on the gantry 311, covering the welding fixture 61 positions on all guide rail mechanisms 40, ensuring that the unloading process is unrestricted.

[0127] The unloading fixture 312 is mounted on the gantry 311 and can move along the gantry 311 by sliding or rolling.

[0128] Optionally, the unloading mechanism 31 includes clamps or other gripping devices capable of alternately gripping the welded workpiece 201 from the welding fixtures 61 on different guide rail mechanisms 40. This alternating operation improves production efficiency, enables continuous feeding, and reduces manual intervention, thereby increasing unloading efficiency.

[0129] Specifically, in actual operation, the unloading fixture 312 first moves above the first guide rail mechanism 40, clamps the welded workpiece, and removes it. It then moves above the second guide rail mechanism 40 and repeats the same operation. In this way, the unloading mechanism 31 can quickly and orderly complete the unloading of the welded workpieces 201 from all guide rail mechanisms 40.

[0130] In some such Figure 3In the specific embodiment shown, the unloading mechanism 31 further includes: a horizontal guide rail 313, a first platform 314, a lifting guide rail 315, and a second platform 316. The horizontal guide rail 313 is mounted on the gantry frame 311 and is located above all the guide rail mechanisms 40. The first platform 314 is movable along the horizontal guide rail 313. The lifting guide rail 315 is vertically mounted on the first platform 314. The second platform 316 is vertically movably mounted on the lifting guide rail 315, and the unloading fixture 312 is mounted on the second platform 316.

[0131] Specifically, the horizontal guide rail 313 is mounted on the gantry 311 and located directly above all the guide rail mechanisms 40, providing a track for the horizontal movement of the first platform 314. This layout allows the unloading fixture 312 to cover the welding fixture 61 positions on all the guide rail mechanisms 40, ensuring a comprehensive and seamless unloading range.

[0132] The first platform 314 is movable along the horizontal guide rail 313 and is driven by a drive device to achieve precise lateral positioning. As a carrier, it integrates the lifting guide rail 315 and the second platform 316, thereby providing the unloading fixture 312 with horizontal adjustment capability.

[0133] The lifting guide rail 315 is vertically set on the first platform 314 to provide vertical movement support for the second platform 316, so that the unloading fixture 312 can flexibly adapt to welding fixtures 61 and welded workpieces 201 of different heights.

[0134] Optionally, the unloading mechanism 31 includes a lead screw or linear module drive. A lifting track is mounted on the lead screw or linear module to achieve accurate control over the height changes of the second platform 316.

[0135] The second platform 316 can be vertically moved and mounted on the lifting guide rail 315, and directly supports the unloading fixture 312.

[0136] Optionally, the unloading fixture 312 uses grippers 3122, suction cups, or other gripping devices to pick up the welded workpiece 201 from the welding fixture 61.

[0137] In the above technical solution, by combining the horizontal movement of the first platform 314 and the vertical movement of the second platform 316, the unloading fixture 312 can be precisely positioned within the operating space to complete the alternating unloading task.

[0138] The following describes a specific working process: First, the first platform 314 moves along the horizontal guide rail 313 above the target guide rail mechanism 40. Then, the second platform 316 descends to a suitable height via the lifting guide rail 315, aligning the unloading fixture 312 with the welded workpiece 201 on the welding fixture 61. Finally, the unloading fixture 312 picks up the workpiece and removes it, returning to its initial position to prepare for the next operation.

[0139] According to some optional embodiments, in combination Figure 1 and Figure 3 The unloading fixture 312 also includes a clamp seat 3121 and a gripper 3122. The clamp seat 3121 is located above the guide rail mechanism 40.

[0140] The clamp holder 3121 is located above the guide rail mechanism 40. During its movement, it will not interfere with the guide rail mechanism 40 or other components, thus improving the clamping accuracy.

[0141] The grippers 3122 are arranged in pairs at the bottom of the clamping base 3121, and the grippers 3122 are retractable on the clamping base 3121.

[0142] The paired grippers 3122 can form a symmetrical clamping force on the workpiece, thereby distributing the force more evenly and avoiding the workpiece tilting or slipping due to unilateral force.

[0143] The gripper 3122 can flexibly open or close as needed to adapt to gripping workpieces of different sizes. This opening and closing function not only improves the operational flexibility of the gripper 3122, but also ensures the accuracy and stability of the gripping process, while enhancing the versatility of the unloading mechanism 31.

[0144] Optionally, the unloading fixture 312 also includes a drive unit for driving the movement of the gripper 3122. The drive unit can be a cylinder, hydraulic rod, or motor, etc.

[0145] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 5 The welding workstation 100 also includes a material unloading platform 32. The material unloading platform 32 is located in the unloading area 3. The material unloading platform 32 is used to receive the welded workpiece 201 unloaded by the unloading mechanism 31 and to move the welded workpiece 201 out.

[0146] The unloading platform 32 serves as a temporary receiving point for the welded workpiece 201, ensuring that the welded workpiece 201 smoothly transitions from the unloading mechanism 31 to subsequent processes or storage areas.

[0147] Optionally, the unloading platform 32 includes a conveyor belt. The welded workpiece 201 can be transferred to the next process or packaging area using a roller or chain conveyor belt.

[0148] Optionally, the unloading platform 32 may also include a robotic arm, which can be integrated to grab the workpiece and place it in a designated position.

[0149] Optionally, the unloading platform 32 is inclined, thereby using gravity to move the welded workpiece 201 along the slide or ramp to the collection area, which is suitable for simple scenarios.

[0150] In some specific embodiments, such as Figure 5 As shown, the unloading platform 32 includes an unloading track 322 and an unloading seat 324. The unloading track 322 extends along the material conveying direction, with one end located below the unloading mechanism 31 and the other end located on the side of the unloading mechanism 31 away from the welding area 2. The unloading seat 324 is movably mounted on the unloading track 322 and is used to receive the welded workpiece 201.

[0151] In the above technical solution, the unloading track 322 extends along the material conveying direction, with one end located directly below the unloading mechanism 31 to receive the welded workpiece 201 unloaded from the unloading mechanism 31. The other end extends to the side of the unloading mechanism 31 away from the welding area 2, facilitating the removal of the workpiece from the welding workstation 100. This layout ensures a clear and efficient workpiece flow path, avoiding interference with other areas.

[0152] The unloading seat 324 is movably mounted on the unloading track 322 and is used to carry the welded workpiece 201. When the unloading mechanism 31 places the welded workpiece 201 on the unloading seat 324, the unloading seat 324 can move along the unloading track 322 to transport the workpiece from the unloading area 3 to the designated position.

[0153] Optionally, the feeder 324 can be moved automatically or manually.

[0154] In some alternative embodiments, see Figure 1 and Figure 2 The welding workstation 100 also includes a base 4. The base 4 includes a loading area 1, a welding area 2, and an unloading area 3. The loading mechanism 10, the welding mechanism 20, the unloading mechanism 31, and the guide rail mechanism 40 are mounted on the base 4. At least a portion of the unloading platform 32 is located on the base 4.

[0155] In some embodiments, combined with Figure 6 The welding fixture 61 also includes a main frame 611, a mounting plate 612, and an extendable clamping assembly. Here, the extendable clamping assembly can adapt to workpieces of different sizes by adjusting the extension distance, achieving flexible and firm clamping, thereby improving the versatility and operational efficiency of the welding fixture 61, while ensuring the stability and consistency of the workpiece during the welding process.

[0156] Optionally, such as Figure 6As shown, the clamping assembly includes at least one of the following: a top frame transverse clamping assembly 613, a top frame longitudinal clamping assembly 614, a top frame vertical clamping assembly 615, a bottom frame transverse clamping assembly 616, a bottom frame longitudinal clamping assembly 617, and a bottom frame vertical clamping assembly 618. The top frame transverse clamping assembly 613, the top frame longitudinal clamping assembly 614, and the top frame vertical clamping assembly 615 correspond to the upper region of the workpiece, while the bottom frame transverse clamping assembly 616, the bottom frame longitudinal clamping assembly 617, and the bottom frame vertical clamping assembly 618 correspond to the lower region of the workpiece. This facilitates multi-faceted constraint of workpieces of various shapes through multi-directional clamping forces.

[0157] In some alternative embodiments, see Figure 6 The welding fixture 61 further includes at least one of the following: a front end fixing component 619 for the side beam, a front end outer pressing component 620 for the side beam, a rear end fixing component 621 for the side beam, a middle inner pressing component 623 for the side beam, a middle inner pressing component for the side beam, and a frame reinforcing beam 629 fixing component 624.

[0158] The front end fixing component 619 and the rear end fixing component 621 of the side beam are used to ensure the stability of the positions of both ends of the workpiece, while the corresponding outer clamping components apply pressure from the outside to prevent the workpiece from shifting or deforming during the welding process, which helps to improve the stability of the workpiece and thus improve the welding accuracy and efficiency.

[0159] The inner clamping assembly in the middle of the side beam provides additional support, further enhancing the overall stability of the workpiece, especially suitable for long or thin-walled workpieces.

[0160] The frame reinforcing beam 629 and the fixing component 624 are used to provide additional reinforcing structure, thereby improving the overall structural strength of the welding fixture 61.

[0161] Optionally, refer to Figure 6 The welding fixture 61 also includes an electrical box 625. The electrical box 625 is used to centrally install control components to realize the electrified operation and precise control of the welding fixture 61.

[0162] Optionally, refer to Figure 6 The welding fixture 61 also includes a control button 626. Here, the control button 626 is used to manually operate the welding fixture 61, allowing for convenient and flexible adjustment of the clamping components.

[0164] Optionally, refer to Figure 6The welding fixture 61 also includes a workpiece support plate 628. The workpiece support plate 628 is used to support the workpiece, ensuring the stability of the workpiece during the welding process, thereby improving the welding accuracy.

[0165] Optionally, refer to Figure 6 The welding fixture 61 also includes a reinforcing beam 629. The reinforcing beam 629 helps to enhance the structural strength of the welding fixture 61 and ensures stability when bearing heavy workpieces.
