Description

Technical Field

[0001] This application relates to the field of laser welding technology, specifically to a push-separation structure for a laser welding fixture. Background Technology

[0002] Welding is a technique that joins metal sheets of different materials, thicknesses, strengths, or properties into a single sheet using welding processes. It is widely used in industrial manufacturing, playing a crucial role, particularly in industries such as automobile manufacturing. Before welding, the metal sheets need to be fixed to a welding platform. Typically, a clamping mechanism holds the metal sheets in place and then presses the weldment together. However, due to the surface aura of the metal sheets and the welding platform, and the relatively thin thickness of the metal sheets, after welding, the metal sheets often adhere and stick to the welding platform, making subsequent removal of the metal sheets difficult. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a laser welding fixture that assists in separating the material plate from the welding platform for easy material plate pickup. The technical solution is as follows:

[0004] The laser welding fixture has a push-out separation structure, including a welding platform for placing the welding material plate;

[0005] A clamping mechanism is used to fix the material plate on the welding platform;

[0006] The welding platform has at least one receiving cavity and a flow channel connecting the receiving cavity, and a driving medium flows in the flow channel;

[0007] Each of the receiving cavities is equipped with a pushing assembly, which is driven by the driving medium to reciprocate along the receiving cavity, for separating or fixing the material plate from the welding platform.

[0008] Preferably, the pushing assembly includes a sliding block and at least one sealing member disposed between the sliding block and the sidewall of the receiving cavity.

[0009] More preferably, the sliding block is provided with a mounting groove, and the sealing component is disposed in the mounting groove.

[0010] Preferably, it further includes a push rod, which is disposed on the pushing assembly near the side of the material plate, and the diameter of the push rod is smaller than the diameter of the sliding block.

[0011] Preferably, it also includes a circulation channel, which is formed on the welding platform to connect the two sides of the push assembly.

[0012] Preferably, it further includes a limiting component for limiting the position of the pushing component, the limiting component being disposed within the receiving cavity.

[0013] More preferably, the limiting component includes a first limiting ring and a second limiting ring, the first limiting ring and the second limiting ring being respectively disposed on both sides of the pushing component.

[0014] The beneficial effects of this application are as follows:

[0015] (1) This application drives the push assembly to move upward, and sends the gas in the first cavity into the space between the material plate and the welding platform to separate the material plate from the welding platform, thereby making it easier to pick up the material plate after welding.

[0016] (2) Secondly, the push assembly is equipped with a push rod. When the push assembly moves upward, it can simultaneously drive the push rod to extend and lift the material plate. In conjunction with the push assembly, the separation effect between the material plate and the welding platform can be further improved.

[0017] (3) Based on the above, the welding platform is provided with a circulation channel connecting both sides of the push assembly, which can actively and continuously supply gas between the welding platform and the material plate. In addition, the push rod can further prevent the material plate from sticking to the welding platform. At the same time, it can provide negative pressure in the first cavity to fix the material plate, eliminating the need for a clamping mechanism. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] See Figures 1 to 4 To further elaborate on this application:

[0031] Combination Figure 1 The laser welding fixture has a push-and-separate structure, including a welding platform 10 and a clamping mechanism (not shown). The clamping mechanism is located on the top of the welding platform 10. The welding platform 10 is used to place the welding material plate 00. The clamping mechanism is used to fix the material plate 00 on the welding platform 10 to prevent the material plate 00 from shifting during welding.

[0032] The clamping mechanism can be a clamping block driven by a cylinder to clamp the material plate 00, as long as it can fix the material plate 00, and there is no limitation here.

[0033] The welding platform 10 has at least one receiving cavity 30 and a flow channel 20 communicating with the receiving cavity 30. A driving medium flows in the flow channel 20. The receiving cavity 30 includes a first cavity 310 and a second cavity 320. The first cavity 310 communicates with the outside, and the second cavity 320 communicates with the flow channel 20. The driving medium can be air, which can reduce pollution. The flow channel 20 can be connected to an air supply device and an air extraction device through electromagnetic reversing valves to ensure the flow of the driving medium.

[0034] Each of the receiving cavities 30 is provided with a pushing assembly 40. The pushing assembly 40 is driven by the driving medium to reciprocate along the receiving cavity 30, which is used to separate or fix the material plate 00 from the welding platform 10. By driving the pushing assembly 40 to move along the receiving cavity 30, the material plate 00 is separated from the welding platform 10, making it easier to remove the material plate from the welding platform. Compared with the prior art, the clamping mechanism can be eliminated.

[0035] like Figure 1 As shown, under normal conditions, the push assembly 40 is housed in the receiving cavity 30, the flow channel 20 is not connected to the air supply device and the air extraction device, and the push assembly 40 is in a stationary state in the receiving cavity 30.

[0036] like Figure 2 As shown, when the material plate 00 is placed on the welding platform 10, the flow channel 20 can be connected to the air extraction device through the electromagnetic reversing valve. Under the action of negative pressure, the push assembly 40 moves further down along the receiving cavity 30, which can assist the clamping mechanism in fixing the material plate 00.

[0037] like Figure 3 As shown, when the welding is completed and the material plate 00 needs to be removed, the flow channel 20 can be connected to the air supply device through the electromagnetic reversing valve. At this time, the driving medium can push the push assembly 40 to lift the material plate 00. That is, the push assembly 40 is driven to send the air in the first cavity 310 into the space between the welding platform 10 and the material plate 00, so that the material plate 00 is separated from the welding platform 10, so that the material plate 00 can be picked up.

[0038] In some embodiments, a sealing ring may be provided at the top opening of the receiving cavity 30; when the material plate 00 is placed on the welding platform 10, the material plate 00 will compress the sealing ring, thereby ensuring that the first cavity 310 is in a sealed state.

[0039] Combination Figure 4 In this embodiment, the pushing assembly 40 includes a sliding block 410 and at least one sealing component 430. The sliding block 410 can be driven to slide up and down within the receiving cavity 30 by the driving medium. The sealing component 430 is disposed between the sliding block 410 and the side wall of the receiving cavity 30. The sealing component 430 can be a sealing ring. The sliding block 410 has a mounting groove 4110, and the sealing component 430 is disposed within the mounting groove 4110, thereby restricting the position of the sealing component 430, preventing the sealing component 430 from detaching, and facilitating the installation of the sealing component 430.

[0040] Combination Figure 3 In some embodiments, a push rod 420 may also be included. The push rod 420 is disposed on the pushing assembly 40 near the material plate 00, and the diameter of the push rod 420 is smaller than the diameter of the sliding block 410. When it is necessary to remove the material plate 00, the sliding block 410 drives the push rod 420 to extend out of the receiving cavity 30, lifting the material plate 00 and separating it from the welding platform 10 for pickup.

[0041] In some embodiments, a circulation channel 60 may be included, which is formed on the welding platform 10 to connect the two sides of the push assembly 40. The circulation channel 60 connects the first cavity 310 and the second cavity 320. When the material plate 00 needs to be removed, a small portion of the driving medium can pass through the circulation channel 60 into the first cavity 310. The positive pressure medium in the first cavity 310 enters between the material plate 00 and the welding platform 10, simultaneously cooperating with the push rod 420 to lift the material plate 00 for pickup.

[0042] This application uses a pusher assembly 40 to lift the material plate 00 from the welding platform 10, and at the same time, it can supply gas between the material plate 00 and the welding platform 10. The pusher assembly 40 is used to separate the material plate 00 from the welding platform 10, so that the material plate after welding can be picked up.

[0043] In some embodiments, a limiting component 50 for limiting the position of the pushing component 40 may also be included. The limiting component 50 is disposed within the receiving cavity 30 and is detachably connected to the receiving cavity 30 to facilitate replacement, maintenance and assembly.

[0044] The limiting component 50 includes a first limiting ring 510 and a second limiting ring 520, which are respectively disposed on both sides of the pushing component 40. Both the first limiting ring 510 and the second limiting ring 520 can be open retaining rings, with an assembly groove for placing the open retaining ring provided on the side wall of the receiving cavity 30, or they can be limiting nuts threadedly connected to the receiving cavity 30. The first limiting ring 510 is located inside the first cavity 310, at the top of the circulation channel 60, and can limit the upper limit position of the pushing component 40, preventing the pushing component 40 from moving out of the receiving cavity 30. The second limiting ring 520 is located inside the second cavity 320, between the flow channel 20 and the circulation channel 60, and can limit the lower limit position of the pushing component 40, preventing the pushing component 40 from obstructing the flow channel 20.
