Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to an edge sealing fixture for laser welding. Background Technology

[0002] In order to ensure work efficiency and stability during laser welding, corresponding fixtures are usually required to fix or position the workpiece so as to achieve precise, efficient and high-quality welding operations during laser welding.

[0003] The design of the fixture directly affects the quality and efficiency of welding, as well as the degree of automation in production.

[0004] When sheet-like workpieces need to be welded at their edges, a fixture is usually used to hold the sheet-like workpiece, and the edges of the held sheet-like workpiece are then laser welded.

[0005] During the welding process, welding can only be performed on local areas of the sheet-like workpiece. After part of the welding is completed, the sheet-like workpiece needs to be rotated so that the remaining edge parts can be welded.

[0006] It can be seen that the existing edge sealing welding process has low efficiency because the welding operation cannot be carried out in one go, and errors may occur after the workpiece position is adjusted, resulting in poor work quality.

[0007] Chinese Patent Publication No. CN115555715A discloses a rotatable laser welding fixture and laser welding device. The invention includes an upper fixture, a lower fixture, and a rotating assembly forming a clamping fixture for positioning the product to be welded. The upper and lower fixtures are closed by hinges and locked by a magnetic block. The rotating assembly rotates clockwise under the drive of an externally configured drive mechanism, which can be a stepper motor. A stepper motor is a type of motor that converts electrical pulse signals into corresponding angular or linear displacements; in this case, it should be a motor that converts to angular displacement. This allows the laser welding device to weld at least four welding positions in the welding area through the laser aperture. This increases the number of different welding angles for the product to be welded, improves the stability of the positioned product, increases work efficiency, and improves product yield.

[0008] In the aforementioned patent, the upper and lower fixtures are hinged together, and the workpiece to be processed is simply positioned between the upper and lower fixtures, resulting in relatively poor positioning stability. Furthermore, the need for a motor to rotate it contributes to its relatively compact structure. Summary of the Invention

[0009] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a highly stable and compact edge-sealing fixture for laser welding.

[0010] The objective of this utility model can be achieved through the following technical solutions:

[0011] A sealing fixture for laser welding is characterized in that it includes a base plate, a pressure plate and a handle. The base plate is flat and has a positioning seat for positioning the workpiece to be welded. The inner end of the handle is hinged to the base plate. The pressure plate is located on the upper part of the base plate. In the initial state, the outer end of the handle is downward and detached from the pressure plate. After applying an external force to make the handle swing upward, the outer end of the handle can be fastened and connected to the pressure plate.

[0012] In the aforementioned edge-sealing fixture for laser welding, the handle is U-shaped, with the two ends of the U-shape being the inner ends.

[0013] In the aforementioned edge-sealing fixture for laser welding, the side of the base plate has a recessed clearance opening, which corresponds one-to-one with the two inner ends of the handle, and the two inner ends of the handle are respectively hinged to the corresponding clearance opening.

[0014] In the aforementioned edge sealing fixture for laser welding, the side of the pressure plate has a recessed relief opening two. The relief opening one and the relief opening two are provided in a one-to-one correspondence. A protruding fastening part is formed between the two relief openings two at the edge of the pressure plate. The middle part of the handle is embedded in the relief opening two and the outer end of the handle is fastened to the fastening part.

[0015] In the aforementioned edge-sealing fixture for laser welding, the outer end of the handle has a recessed positioning hole, and the positioning hole contains a spring and a ball. Under the elastic force of the spring, the ball tends to partially extend out of the positioning hole. When the middle part of the handle is embedded in the two clearance openings, the ball tends to abut against the pressure plate.

[0016] In the aforementioned edge-sealing fixture for laser welding, the positioning hole, spring, and ball form a positioning unit. The positioning units are evenly distributed along the length of the handle, and the ball in each positioning unit tends to abut against the pressure plate.

[0017] In the aforementioned edge-sealing fixture for laser welding, the outer end of the handle has a smoothly transitioned clearance portion.

[0018] In the aforementioned edge-sealing fixture for laser welding, the pressure plate side has a smoothly transitioned clearance section 2.

[0019] The aforementioned edge-sealing fixture for laser welding also includes a flat substrate. A connecting plate is fixedly connected to the pressure plate. The connecting plate is detachably connected to the substrate. There are two connecting plates, which are symmetrically arranged at both ends of the pressure plate.

[0020] Compared with existing technologies, this edge-sealing fixture for laser welding has a stable connection between the base plate and the pressure plate after the pressure plate is connected to the base plate and the handle on the base plate is fastened to the pressure plate.

[0021] The workpiece to be welded is stably positioned between the base plate and the pressure plate on the base plate. Of course, the edge of the workpiece to be welded extends out of the base plate and the pressure plate, which facilitates the welding device to perform welding operations on the edge of the workpiece to be welded.

[0022] Furthermore, the base plate and pressure plate can be fastened together and mounted on the base plate, allowing the workpiece to be welded to be stably transported to the welding device. It can be seen that this fixture not only quickly and stably positions the workpiece to be welded, but also stably transports it to the laser welding area. Its stability is relatively high, and the overall fixture structure is also quite compact. Attached Figure Description

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] like Figure 1 and Figure 2 and Figure 3 and Figure 4 As shown, the edge sealing fixture for laser welding includes a base plate 1, a pressure plate 2, and a handle 3. The base plate 1 is flat and has a positioning seat 1a for positioning the workpiece to be welded. The inner end of the handle 3 is hinged to the base plate 1. The pressure plate 2 is located on the upper part of the base plate 1. In the initial state, the outer end of the handle 3 is downward and detached from the pressure plate 2. After applying external force to make the handle 3 swing upward, the outer end of the handle 3 can be fastened and connected to the pressure plate 2.

[0032] The workpiece to be welded is stably placed on the base plate 1 by the positioning seat 1a. The pressure plate 2 is connected to the upper part of the base plate 1. The handle 3, which was originally hanging down, is flipped upward under the action of external force. After the handle 3 is flipped, its outer end is fastened to the pressure plate 2. After the pressure plate 2 is stably connected to the base plate 1, the workpiece to be welded is also stably positioned between the base plate 1 and the pressure plate 2.

[0033] Since welding is required at the edges of the workpiece to be welded, the width of the workpiece to be welded is greater than the width of the base plate 1 and the pressure plate 2. After the workpiece to be welded is positioned, its outer edge extends out of the base plate 1 and the pressure plate 2.

[0034] Because the center of the workpiece to be welded is tightly pressed and positioned, the welding device can stably perform welding operations on the edges of the workpiece.

[0035] The handle 3 is U-shaped, with the two ends of the U-shape being the inner ends.

[0036] This structure allows the handle 3 to be stably hinged to the edge of the base plate 1.

[0037] The base plate 1 has a recessed clearance opening 1b on its side, and the clearance opening 1b corresponds one-to-one with the two inner ends of the handle 3. The two inner ends of the handle 3 are respectively hinged to the corresponding clearance opening 1b.

[0038] The clearance 1b can avoid the handle 3, and the handle 3 will not be blocked by the base plate 1 during the flipping process.

[0039] The pressure plate 2 has a recessed clearance opening 2a on its side. The clearance opening 1b and clearance opening 2a are provided in a one-to-one correspondence. A protruding fastening part 2b is formed between the two clearance openings 2a at the edge of the pressure plate 2. The handle 3 is embedded in the clearance opening 2a in the middle and the outer end of the handle 3 is fastened to the fastening part 2b.

[0040] The setting of the clearance opening 2a allows the pressure plate 2 to avoid the handle 3, preventing the handle 3 from being obstructed during its swing.

[0041] The handle 3 has a recessed positioning hole 3a at its outer end. The positioning hole 3a contains a spring 4 and a ball 5. Under the elastic force of the spring 4, the ball 5 tends to extend partially out of the positioning hole 3a. When the middle part of the handle 3 is embedded in the clearance opening 2a, the ball 5 tends to abut against the pressure plate 2.

[0042] Under the elastic force of spring 4, ball 5 abuts against pressure plate 2. It can be seen that after handle 3 swings, there is always a gap between the outer end of handle 3 and pressure plate 2. Spring 4 and ball 5 can effectively eliminate the gap, ensuring that pressure plate 2 and base plate 1 are stably connected together.

[0043] The positioning hole 3a, spring 4 and ball 5 form a positioning unit. The positioning units are evenly distributed along the length of the handle 3, and the ball 5 in each positioning unit tends to abut against the pressure plate 2.

[0044] The arrangement of multiple positioning units ensures a stable connection between the pressure plate 2 and the base plate 1.

[0045] The outer end of the handle 3 has a smoothly transitioned avoidance portion 3b.

[0046] The pressure plate 2 has a smooth transition avoidance part 2a on its side.

[0047] The cooperation of the first clearance part 3b and the second clearance part 2a ensures that the outer end of the handle 3 will not touch the edge of the pressure plate 2 during the swinging process.

[0048] It also includes a flat substrate 6, and a connecting plate 7 is fixedly connected to the pressure plate 2. The connecting plate 7 is detachably connected to the substrate 6. There are two connecting plates 7, which are symmetrically arranged at both ends of the pressure plate 2.

[0049] The connecting plate 7 has a recessed connecting hole 7a, and a flexible connecting head 8 is fixedly connected to the substrate 6. In this embodiment, the connecting head 8 is made of rubber material. After the connecting head 8 is embedded in the connecting hole 7a, the two are tightly connected, which can stably connect the pressure plate 2 and the substrate 6 together.

[0050] Of course, applying a relatively large external force can cause the connector 8 to disengage from the connector hole 7a of the connector plate 7, ensuring that the pressure plate 2 can be stably separated from the substrate 6.

[0051] In this edge-sealing fixture used for laser welding, after the pressure plate is connected to the base plate, the handle on the base plate is fastened to the pressure plate, which can stably connect the base plate and the pressure plate.

[0052] The workpiece to be welded is stably positioned between the base plate and the pressure plate on the base plate. Of course, the edge of the workpiece to be welded extends out of the base plate and the pressure plate, which facilitates the welding device to perform welding operations on the edge of the workpiece to be welded.

[0053] Furthermore, the base plate and pressure plate can be fastened together and mounted on the base plate, allowing the workpiece to be welded to be stably transported to the welding device. It can be seen that this fixture not only quickly and stably positions the workpiece to be welded, but also stably transports it to the laser welding area. Its stability is relatively high, and the overall fixture structure is also quite compact.

[0054] In this embodiment, the workpiece to be welded is a VC heat spreader. The raw material for the VC heat spreader includes several sheet-like substrates. After the several substrates are stacked together, their edges are welded together to obtain the finished VC heat spreader.

[0055] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
