[0002] The slide is composed of multiple segments. Each segment of the slide needs to be welded with corresponding additional structures during manufacturing. Currently, during slide welding, the welding station is often fixed. The segment to be welded needs to be installed at the welding station, and after welding, the finished product needs to be removed from the welding station. Repeated disassembly and assembly increases the welding time and makes the efficiency relatively low. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a slide rail spot welding device, comprising a welding torch, a robotic arm, and a welding platform.

The welding platform is used to rotate horizontally so that the welding stations alternately approach the robotic arm. The welding torch is connected to the end of the robotic arm, and the robotic arm is used to drive the welding torch to move so that the welding torch welds the workpiece to be welded at the adjacent welding station.

[0005] Optionally, each welding station includes two first positioning structures. The bottom of each first positioning structure is connected to the welding platform, and the top of the first positioning structure is provided with an upward-opening groove.

Therefore, they should not be construed as limitations on the invention.

[0023] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in sequences other than those illustrated or described herein.

[0024] Combination Figures 1 to 3 As shown, this utility model provides a slide rail re-pressing spot welding device, including a welding torch, a robotic arm 1 and a welding platform 2. The welding platform 2 is provided with two welding stations 3, each welding station 3 is used to fix the workpiece to be welded. The welding platform 2 is used to rotate horizontally so that the two welding stations 3 alternately approach the robotic arm 1. The welding torch is connected to the end of the robotic arm 1. The robotic arm 1 is used to drive the welding torch to move so that the welding torch welds the workpiece to be welded on the adjacent welding station 3.

[0025] Specifically, the welding torch is mounted on the end (execution end) of the robotic arm 1 via threaded fasteners. The robotic arm 1 has multiple degrees of freedom, allowing adjustment of the welding angle of the welding torch within space during operation. A welding platform 2 can be placed in front of the robotic arm 1, with two welding stations 3 set at its upper end. Initially, a workpiece to be welded can be fixed at one welding station 3. The welding platform 2 then rotates, moving the current welding station 3 to the robotic arm 1. The robotic arm 1 then moves the welding torch to perform welding. The next workpiece to be welded is then installed at the remaining welding station 3. After the previous workpiece is welded, the welding platform 2 rotates again, moving the next workpiece to be welded to the robotic arm 1. While the welding torch is welding the next workpiece, the previously welded workpiece can be removed from the welding station 3, and another workpiece can be installed. This continuous rotation of the two welding stations 3 shortens the welding process time.

[0026] Therefore, in this embodiment, by connecting the welding torch to the end of the robotic arm 1, the operation of the robotic arm 1 can realize the movement of the welding torch, thereby adjusting the spatial position of the welding torch and thus achieving accuracy in the welding process, thereby reducing manpower input. Furthermore, by setting two welding stations 3 on the welding platform 2, and by setting the welding platform 2 to rotate horizontally, the two welding stations 3 can be rotated during the welding process, so that the two parts to be welded on the two welding stations 3 can be welded alternately, thereby achieving continuous welding and improving welding efficiency.

[0027] Optionally, combined Figure 4 As shown, each welding station 3 includes two first positioning structures 4. The bottom of each first positioning structure 4 is connected to the welding platform 2. The top of the first positioning structure 4 is provided with an upward-opening groove 41. The grooves 41 of the two first positioning structures 4 are respectively used to engage with the two ends of the workpiece to be welded, so that the workpiece to be welded is suspended on the welding platform 2.

[0028] Specifically, the positioning structure can be columns, with two columns located at both ends of the workpiece along its length. The lower end of each column is mounted on the welding platform by bolts, and the upper end of each column is provided with an upward-opening groove 41. The two grooves 41 on the two columns can fix both ends of the workpiece, so that the workpiece is suspended on the welding platform 2 under the positioning of the two grooves 41.

[0029] Thus, by connecting the bottom of each first positioning structure 4 to the welding platform 2, and providing an upward-opening groove 41 at the top of the first positioning structure 4, the groove 41 is used to engage with the end of the workpiece to be welded. The two first positioning structures 4 can fix the workpiece to be welded while suspending it above the welding platform 2. In this way, during the welding process, the workpiece to be welded can be as close as possible to the end of the robotic arm 1, avoiding interference from the welding platform 2 on the welding position of the welding gun, thereby improving welding efficiency.

[0030] Optionally, combined Figure 4 As shown, each welding station 3 includes a second positioning structure, which is located between two first positioning structures 4. The bottom of the second positioning structure is connected to the welding platform 2, and the top of the second positioning structure is provided with a horizontally retractable movable block 5, which is used to abut against the end of the workpiece in the width direction.

[0031] Specifically, the second positioning structure is located between the two first positioning structures, or it can be understood as the second positioning structure being located in the middle of the workpiece to be welded. The second positioning structure may include a cylinder 11 that extends and retracts in the horizontal direction and a movable block 5 connected to the extension end of the cylinder 11. The cylinder body of the cylinder 11 can be mounted on the welding platform 2 through a corresponding support seat. After the two first positioning structures 4 fix the workpiece to be welded, the cylinder extends horizontally so that the movable block 5 abuts against the end of the workpiece in the width direction. Thus, the movable block 5, together with the two grooves 41 on the two first positioning structures 4, can horizontally clamp the workpiece to be welded to ensure the stability of the workpiece in the horizontal direction. For example, after the workpiece to be welded is initially positioned by the two grooves 41 of the two first positioning structures 4, there may be a gap between the workpiece to be welded and the two grooves 41 due to dimensional errors. The existence of the gap may cause the workpiece to move horizontally. Therefore, by using the movable end 5 to abut against the end of the workpiece in the width direction, the problem of horizontal movement of the workpiece caused by the gap can be eliminated. The second positioning structure can also be replaced by other structures that can abut against the end of the workpiece in the width direction.

[0032] Thus, the second positioning structure is located between the two first positioning structures 4, and the bottom of the second positioning structure is connected to the welding platform 2. The top of the second positioning structure is provided with a horizontally retractable movable block 5. The movable block 5 is used to abut against the end of the workpiece in the width direction. After the movable block 5 abuts against the end of the workpiece in the width direction, the movable block 5 and the two first positioning structures 4 clamp the workpiece in the horizontal direction to improve the stability of the workpiece.

[0033] Optionally, combined Figure 4 As shown, each welding station 3 includes a third positioning structure, and the movable end 6 of the third positioning structure is used to press down the workpiece to be welded.

[0034] Specifically, the third positioning structure may include a servo motor and a pressure plate (i.e., movable end 6) connected to the drive end of the servo motor. After the movable block 5 of the second positioning structure abuts against the workpiece to be welded, the servo motor drives the pressure plate to rotate around the shaft of the servo motor, so that the pressure plate changes from a vertical state to a horizontal state, thereby causing the pressure plate to press down on the workpiece to be welded in a horizontal state. The pressure plate and the two grooves 41 of the two first positioning structures 4 limit the workpiece to be welded in the vertical direction.

[0035] Thus, the movable end 6 of the third positioning structure is used to press down on the workpiece to be welded. The third positioning structure, the second positioning structure, and the two first positioning structures 4 can cooperate with each other to achieve multi-directional positioning of the workpiece to be welded, thereby improving the stability of the workpiece to be welded.

[0036] Optionally, the movable end 6 of the third positioning structure is provided with a rubber pad.

[0037] Specifically, the rubber pad is installed with screws on the end of the movable end 6 that is in contact with the workpiece to be welded. When the movable end 6 presses down on the workpiece to be welded, the direct contact between the movable end 6 and the workpiece to be welded can be reduced, so as to avoid wear of the workpiece by the movable end 6 and ensure the welding quality.

[0038] Optionally, the slide rail spot welding equipment also includes a servo motor, with the drive end of the servo motor facing upward and connected to the welding platform drive.

[0039] Specifically, the servo motor is located below the welding platform 2, with its drive end facing upwards and connected to the welding platform 2 for driving the welding platform 2 to rotate horizontally. Thus, by having the servo motor's drive end facing upwards and connected to the welding platform, precise control of the horizontal rotation of the welding platform 2 can be achieved, ensuring that the rotation of the welding platform 2 allows for accurate movement of the welding station 3.

[0040] Optionally, combined Figures 1 to 3 As shown, the slide rail re-pressing spot welding equipment also includes a protective fence 7 set around the welding platform 2, and a manual passage is reserved on the side of the protective fence 7 opposite to the robotic arm 1.

[0041] Specifically, the protective fence 7 surrounds the welding platform 2, and a manual passage is reserved at the side end of the protective fence 7 opposite to the robotic arm 1. Before or after welding, the manual passage facilitates manual handling or inspection of the welded product. During the welding process, the protective fence 7 can prevent welding slag from splashing everywhere and ensure the cleanliness of the welding environment.

[0042] Optionally, combined Figure 1As shown, guide wheels 9 can be respectively installed on the inner walls of opposite sides of the protective fence 7, and arc-shaped sliding rods 10 can be installed on the opposite sides of the welding platform 2. The sliding rods 9 are located between the two guide wheels 9 and are used to roll in contact with the guide wheels 9 when the welding platform 2 rotates. When the welding platform 2 rotates horizontally within a set angle, the opposite sliding rods 10 can roll in contact with the two guide wheels 9 respectively. Thus, the stability of the horizontal rotation of the welding platform 2 can be improved by the rolling contact between the two guide wheels 9 and the two sliding rods 10, avoiding the problem of inaccurate movement of the welding station 3 caused by the off-center load of the rotating platform.

[0043] Optionally, combined Figure 1 As shown, the welding platform 2 also includes a partition 8, which is installed between the two welding stations 3.

[0044] Specifically, the partition 8 is located in a vertical plane, and the bottom of the partition 8 is installed on the welding platform 2 by bolts. The partition 8 can divide the upper end of the welding platform 2 into two areas, and the two welding stations 3 are located in the two areas respectively. During welding, the partition 8 can isolate the spatter of welding slag.

[0045] Thus, the partition 8 is installed between the two welding stations 3, and the partition 8 separates the two welding stations 3. During welding, it can prevent the slag from splashing, so as to ensure the cleanliness of the welding station 3.

[0046] Optionally, the welding platform 2 is also provided with a temporary storage station for temporarily fixing the workpiece to be welded.

[0047] Specifically, one welding station 3 corresponds to one temporary storage station. During welding, after the workpiece to be welded is installed at welding station 3, another workpiece to be welded can be placed at the temporary storage station. During welding, the two workpieces to be welded can be welded alternately to improve welding efficiency. The finished product after welding can also be placed at the temporary storage station to facilitate the inspection of the welding quality of the finished product after welding, thereby improving the flexibility of the slide rail repress spot welding equipment.

[0048] Optionally, the slide rail spot welding equipment also includes a control system, which is communicatively connected to the robotic arm 1, the welding torch, and the servo motor.

[0049] Specifically, the control process of the control system is as follows: Initially, the robotic arm 1, welding torch, and servo motor receive control signals from the control system to maintain the initial state. When welding is required, after the workpiece to be welded is fixed, the control system controls the servo motor to start. The servo motor drives the welding platform 2 to rotate to the robotic arm 1. Then, the control system controls the robotic arm 1 to run, so that the robotic arm 1 can drive the welding torch to move to the workpiece to be welded. After the welding torch is aligned with the weld seam on the workpiece, the control system controls the welding torch to perform welding while controlling the robotic arm 1 to move the welding torch along the weld seam on the workpiece to be welded, thereby completing the welding of the workpiece to be welded. This automatically realizes the welding of the workpiece to be welded, thereby improving the welding efficiency.

[0050] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
