Description

Technical Field

[0001] This utility model belongs to the field of scanning welding technology, specifically relating to a replaceable quick-release water-cooling structure for the internal structure of a high-power scanning welding galvanometer. Background Technology

[0002] High-power scanning welding galvanometers are crucial optical components in laser welding equipment, used to reflect and orient the laser beam, controlling its transmission and focusing. However, under high-temperature conditions, scanning welding galvanometers may experience various problems, affecting their performance and lifespan. Specifically, high temperatures can lead to the following issues:

[0003] 1. The performance of the scanning welding galvanometer itself may change at high temperatures. Due to the different coefficients of thermal expansion of materials, increased temperature may cause deformation of the galvanometer, leading to optical path deviation and decreased imaging quality. Simultaneously, high temperatures can also cause thermal stress on the galvanometer surface, further affecting the quality and direction of its reflected beam. These issues all reduce the working efficiency and stability of the scanning welding galvanometer.

[0004] 2. High temperatures can also cause the materials of the scanning welding galvanometer to melt or oxidize. Some materials are easily oxidized at high temperatures, even forming oxide films, which affect laser reflection and refraction. Some plastic materials and adhesives may melt or deform at high temperatures, causing the galvanometer to lose its fixation and detach.

[0005] To avoid the impact of high temperatures on the scanning welding galvanometer, certain measures need to be taken to improve working conditions. Currently, water cooling holes are opened on the external mounting plate, and a circulating water circuit is set up on the external mounting plate for heat dissipation. Although this method is simple, after long-term use, the metal parts are prone to rust and corrosion, which can lead to water circuit contamination or even blockage. This makes it necessary to replace the mounting plate during maintenance. However, the mounting plate has multiple components installed, which makes maintenance and replacement troublesome. Utility Model Content

[0006] This invention proposes a replaceable, quick-release water-cooling structure for the interior of a high-power scanning welding galvanometer, which not only cools the scanning welding galvanometer but also facilitates future maintenance and replacement.

[0007] Therefore, the technical solution adopted by this utility model is as follows: a replaceable quick-release water-cooling structure for the interior of a high-power scanning welding galvanometer, including a water-cooling plate disposed between the galvanometer bracket and the external mounting plate, a water-cooling channel disposed inside the water-cooling plate, and connectors for cooling water to enter and exit disposed at intervals on the upper and lower sides of the water-cooling plate near the outer side, and a high thermal conductivity medium disposed between the water-cooling plate and the galvanometer bracket.

[0008] As a preferred embodiment of the above scheme, the high thermal conductivity medium is configured as a thermal pad.

[0009] Further preferably, the water cooling channel includes two horizontally arranged inlet and outlet water channels connected to the connector, and several vertical connecting channels are arranged between the two inlet and outlet water channels.

[0010] Further preferably, one end of the connecting channel passes through the inlet and outlet water channels and is provided with a machining hole to facilitate the processing of the connecting channel, and each machining hole is provided with a plug to prevent cooling water from leaking out.

[0011] Further preferably, the machining hole is configured as a T-shaped hole, with the smaller end being closer to the water inlet / outlet channel.

[0012] More preferably, the external mounting plate includes a bottom plate disposed on the bottom surface of the galvanometer bracket, a back plate on the rear side of the galvanometer bracket, and a side plate on the side of the galvanometer bracket, and the water-cooling plate is disposed between the galvanometer bracket and the back plate.

[0013] In a further preferred embodiment, the water-cooled plate is provided with bolt holes for the bolts of the galvanometer bracket to pass through on the back plate, and the bolt holes are arranged to avoid the water-cooling channels.

[0014] Further preferred, the two connectors are located at the furthest point of the vertical spacing, and the connectors are quick-connect fittings.

[0015] The beneficial effects of this utility model are as follows: cooling is achieved by attaching a water-cooled plate to the outside. When there is rust, corrosion or blockage due to other reasons, the water-cooled plate can be directly replaced simply by removing the connecting bolts between the galvanometer bracket and the mounting plate. This not only facilitates subsequent quick repair and replacement but also allows for direct replacement on-site. Furthermore, a high thermal conductivity medium is provided to facilitate heat transfer. Attached Figure Description

[0019] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0020] like Figures 1-2As shown, a replaceable, quick-release water-cooling structure for the interior of a high-power scanning welding galvanometer mainly consists of a water-cooling plate 2 and a high thermal conductivity medium. The water-cooling plate 2 is positioned between the galvanometer support 1 and the external mounting plate, while the high thermal conductivity medium is positioned between the water-cooling plate 2 and the galvanometer support 1. The high thermal conductivity medium can be a thermal pad, but it can also be a coated liquid metal or nanofluid, etc.

[0021] To achieve the cooling effect of the water-cooled plate, a water-cooling channel is provided inside the water-cooled plate 2, and at the same time, connectors 3 for cooling water to enter and exit are provided at intervals on the upper and lower sides near the outer side of the water-cooled plate 2.

[0022] To improve the cooling effect, the water cooling channel includes two horizontally arranged inlet and outlet water channels 2a connected to the connector 3. Several vertical connecting channels 2b are arranged between the two inlet and outlet water channels 2a. Of course, the water cooling channel can be configured as an S-shaped channel or other structures with a longer cooling channel.

[0023] To further increase the cooling channels, the two connectors 3 are positioned at the furthest point between the upper and lower gaps. Ideally, the connectors should be quick-connect fittings.

[0024] To facilitate the processing of the water-cooled plate, one end of the connecting channel 2b passes through the inlet and outlet water channels and is provided with a processing hole 2c to facilitate the processing of the connecting channel. Each processing hole 2c is provided with a plug to prevent the cooling water from leaking out.

[0025] To facilitate cleaning of the various connection channels, the machining hole 2c is set as a T-shaped hole, with the end near the inlet / outlet water channel 2a being the smaller end, so that the plug can be detachably installed in the machining hole.

[0026] The external mounting plate includes a base plate 5 on the bottom surface of the galvanometer bracket, a back plate 6 on the rear side of the galvanometer bracket, and a side plate 7 on the side of the galvanometer bracket. The base plate is provided with an emission hole for the laser to be emitted after passing through the galvanometer bracket. The side plate is provided with an entry hole to facilitate the laser to enter the galvanometer bracket. The back plate is used as a mounting plate for mounting the galvanometer bracket on other components. Preferably, the water-cooling plate 2 is located between the galvanometer bracket 1 and the back plate 6. Since the back plate does not have through holes, the cooling area is large and the cooling effect is good.

[0027] To facilitate the installation of the water-cooled plate, a bolt through hole 2d is provided on the water-cooled plate 2 for the bolts of the galvanometer bracket to pass through on the back plate. The bolt through hole 2d is set to avoid the water-cooling channel, so that the water-cooled plate does not need to be equipped with bolts separately, but can directly use the mounting bolts between the back plate and the galvanometer bracket, and at the same time, the original structure does not need to be changed.
