Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a laser dotting fixture. 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] Existing fixtures are typically used for simple workpiece support, and laser welding equipment still requires operators to accurately locate the welding position. It can be seen that during the operation, not only does the workpiece position need to be corrected by the operator, but the welding position also needs to be found. This operational method results in relatively low efficiency, and the welding quality is mainly determined by the operator's experience, leading to poor stability and low overall efficiency.

[0005] Chinese patent publication number CN212634675U discloses a laser welding fixture, which includes a fixture base plate, a workpiece welding part on the fixture base plate, and a workpiece cooling channel formed on the fixture base plate. The workpiece cooling channel has an inlet end and an outlet end. The inlet end is connected to an external cooling medium source, and the outlet end is located on the workpiece welding part. The cooling medium from the cooling medium source flows in from the inlet end and flows out from the outlet end through the workpiece cooling channel to cool the workpiece placed on the workpiece welding part during the laser welding process.

[0006] It can be seen that the aforementioned patents mainly address rapid cooling during the welding process, but do not disclose technical solutions for workpiece position correction and welding position guidance. These patents still suffer from low operational efficiency and unreliable welding quality. Summary of the Invention

[0007] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a laser dotting fixture that is both stable and efficient in operation, and has a compact structure.

[0008] The objective of this utility model can be achieved through the following technical solutions:

[0009] A laser dotting fixture, characterized in that it comprises a base plate, a limiting plate, a pressure plate, and a positioning assembly. The base plate is elongated and has a recessed positioning seat on its upper part. The limiting plate is rectangular and is connected to the upper part of the base plate via the positioning assembly. The pressure plate matches the inner cavity of the limiting plate and is located within the limiting plate. The lower part of the pressure plate abuts against the positioning seat on the base plate. A welding portion for embedding a laser welding device is also provided between the limiting plate and the pressure plate.

[0010] In the aforementioned laser dot grid fixture, the positioning component includes a positioning post fixed to the base plate and a positioning hole penetrating the limiting plate, wherein the positioning post can be embedded in the positioning hole.

[0011] The aforementioned laser dotting fixture also includes a positioning cylinder with an inner cavity that matches the positioning post. The positioning cylinder is fixed to the positioning hole, and the positioning post can be embedded in the positioning cylinder.

[0012] In the aforementioned laser dotting fixture, the positioning hole, positioning cylinder, and corresponding positioning post form a positioning unit, and the number of positioning units is several.

[0013] In the aforementioned laser dot grid fixture, the size of the upper port on the limiting plate is larger than the size of the lower port, and there is a smooth transition between the upper and lower ports.

[0014] In the aforementioned laser dotting fixture, the pressure plate is in the shape of a long plate, and the inner corner of the limiting plate has an arc-shaped recessed clearance notch.

[0015] In the aforementioned laser dot matrix fixture, the width of the upper part of the pressure plate is smaller than the width of the lower part of the pressure plate, and the side of the pressure plate smoothly transitions from the upper part to the lower part of the pressure plate.

[0016] In the aforementioned laser dotting fixture, the side of the pressure plate has a recessed welding notch that extends from the upper part of the pressure plate to the lower part of the pressure plate.

[0017] In the aforementioned laser dot mesh fixture, the upper part of the welding notch is larger than the lower part, and the upper part of the welding notch transitions smoothly to the lower part.

[0018] In the aforementioned laser dotting fixture, a handle is fixedly connected to the upper part of the pressure plate.

[0019] Compared with existing technologies, the limiting plate in this laser dotting fixture can be easily and quickly installed on the upper part of the base plate, and the pressure plate can be easily and quickly installed inside the limiting plate. Therefore, the workpiece to be welded can be quickly positioned between the base plate and the limiting plate. At the same time, since there is a welding part between the limiting plate and the pressure plate for the laser device to perform welding, the welding device only needs to enter the welding part during the welding process. Using this fixture not only results in high work efficiency but also high welding accuracy. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] 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.

[0030] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 As shown, this laser dot grid fixture includes a base plate 1, a limiting plate 2, a pressure plate 3, and a positioning assembly. The base plate 1 is elongated and has a recessed positioning seat 1a on its upper part. The limiting plate 2 is square and is connected to the upper part of the base plate 1 through the positioning assembly. The pressure plate 3 matches the inner cavity of the limiting plate 2 and is located inside the limiting plate 2. The lower part of the pressure plate 3 abuts against the positioning seat 1a of the base plate 1. There is also a welding part between the limiting plate 2 and the pressure plate 3 for a laser welding device to be embedded.

[0031] The limiting plate 2 is positioned and connected to the base plate 1 by the positioning component, and the pressure plate 1 is positioned and connected inside the limiting plate 2, ultimately ensuring that the pressure plate 3 is stably located on the upper part of the base plate 1.

[0032] The base plate 1, the limiting plate 2, and the pressure plate 3 are all independent. This structure ensures that the workpiece to be welded can be stably placed between the base plate 1 and the limiting plate 2.

[0033] Once the workpieces are positioned and connected, the welding device can begin welding operations from the welding section. In other words, there's no need to search for the welding position separately; once the workpieces are positioned, the corresponding welding operation can be quickly performed at the welding section.

[0034] The positioning component includes a positioning post 4 fixed to the base plate 1 and a positioning hole 2a penetrating the limiting plate 2, wherein the positioning post 4 can be embedded in the positioning hole 2a.

[0035] Since the positioning post 4 is fixed to the base plate 1, once the positioning post 4 is inserted into the positioning hole 2a, the limiting plate 2 and the base plate 1 can be positioned and connected.

[0036] It also includes a positioning cylinder 5 with an inner cavity that matches the positioning post 4. The positioning cylinder 5 is fixed to the positioning hole 2a, and the positioning post 4 can be embedded in the positioning cylinder 5.

[0037] After prolonged use, the positioning cylinder 5 can be replaced separately, which can appropriately reduce the cost of using the fixture.

[0038] The positioning hole 2a, the positioning cylinder 5 and the corresponding positioning post 4 form a positioning unit, and there are several positioning units.

[0039] In this embodiment, the long plate-shaped base plate 1 has four positioning units, two of which are located at two bends at one end of the base plate 1, and the other two are located at two bends at the other end of the base plate 1.

[0040] Multiple positioning units stably connect the limiting plate 2 and the base plate 1 together.

[0041] The upper port of the limiting plate 2 is larger than the lower port, and there is a smooth transition between the upper and lower ports.

[0042] This structure allows the pressure plate 3 to be smoothly embedded into the limiting plate 2.

[0043] The pressure plate 3 is in the shape of a long plate, and the inner corner of the limiting plate 2 has an arc-shaped recessed avoidance notch 2b.

[0044] The design of the clearance notch 2b can prevent jamming between the pressure plate 1 and the limiting plate 2.

[0045] The width of the upper part of the pressure plate 1 is smaller than the width of the lower part of the pressure plate 3, and the side of the pressure plate 3 smoothly transitions from the upper part to the lower part of the pressure plate 3.

[0046] This structure allows the pressure plate 3 to be inserted into the limiting plate 2 more easily and smoothly.

[0047] The pressure plate 3 has a recessed welding notch 6a on its side, which extends from the upper part of the pressure plate 3 to the lower part of the pressure plate 3.

[0048] The upper part of the welding notch 6a is larger than the lower part, and the upper part of the welding notch 6a transitions smoothly to the lower part.

[0049] The welding notch 6a and the inner side of the limiting plate 2 stably form the welding part of the guide welding device. At the same time, the upper dimension of the welding notch 6a is larger than the lower dimension, and this structure allows the welding device to stably enter the set welding operation area.

[0050] A handle 7 is fixedly connected to the upper part of the pressure plate 3.

[0051] The pressure plate 3 can be easily picked up using the handle 7.

[0052] In this laser dotting fixture, the limiting plate can be easily and quickly installed on the upper part of the base plate, and the pressure plate can be easily and quickly installed inside the limiting plate. Therefore, the workpiece to be welded can be quickly positioned between the base plate and the limiting plate. At the same time, since there is a welding part between the limiting plate and the pressure plate for the laser device to perform welding, the welding device only needs to enter the welding part during the welding process. Using this fixture not only results in high work efficiency but also high welding accuracy.

[0053] In this embodiment, the EV board, resin board and MESH mesh board are connected and laser welded to prepare a VC heat spreader.

[0054] A vapor chamber, also known as a heat exchanger, is a highly efficient heat dissipation solution widely used in high-performance electronic devices such as laptops, smartphones, and data center servers. It utilizes the principle of phase change to achieve rapid and uniform heat transfer, thereby improving the device's heat dissipation efficiency and stability.

[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.
