These chips are arranged and combined into various basic circuit units, connected by aluminum wires of different diameters, and then protected by silicone and plastic casings to form the finished power module. Power modules are widely used in automobiles, frequency converters, and other fields.

[0003] With the rise of the semiconductor industry, power modules are being used more and more widely in industrial production. As the main heat dissipation component of power modules, the heat dissipation substrate of power modules is particularly important.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The serial numbers assigned to components in this document, such as "first," "second," etc., are merely for distinguishing the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages). In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0025] Please see Figure 1 and Figure 2 This utility model discloses an automated sandblasting production line, characterized in that it includes: a first translation mechanism 1, a second translation mechanism 2, a first robotic arm 3, a second robotic arm 4, a conveying mechanism 5, and a sandblasting machine 6.

[0026] The first robotic arm 3 is mounted on the first translation mechanism 1, the second robotic arm 4 is mounted on the second translation mechanism 2, and the conveying mechanism 5 is mounted on the sandblasting machine 6. The first translation mechanism 1 and the second translation mechanism 2 are located at the two ends of the conveying mechanism 5, respectively.

[0027] The part to be sandblasted can be a power module heat sink substrate, but is not limited to power module heat sink substrates.

[0028] Specifically, the first translation mechanism 1 and the second translation mechanism 2 are slide rail and slider assemblies or slide table assemblies. For example, in one specific embodiment, the first translation mechanism 1 is a slide rail and slider assembly, with the slide rail mounted on a bracket and slidably connected to the slider, and the first robotic arm 3 and the second robotic arm 4 respectively mounted on the corresponding sliders.

[0029] Optionally, the conveying mechanism 5 is a conveyor belt. The conveyor belt is existing technology and will not be described in detail here. The conveying speed of the conveyor belt corresponds to the transfer rhythm of the first robotic arm 3 and the second robotic arm 4. This arrangement ensures that the rhythm of the first robotic arm 3 and the second robotic arm 4 grasping the workpiece to be sandblasted corresponds to the rhythm of the conveyor belt transporting the workpiece. The conveyor belt is existing technology and will not be described in detail here. Optionally, in this embodiment, the conveyor belt is arrayed with several placement slots, the size of which is adapted to the size of the workpiece to be sandblasted. The workpieces to be sandblasted are placed one by one into the placement slots. Preferably, the placement slot includes a bottom wall and side walls protruding from the bottom wall. The bottom wall and side walls of the placement slot are hollowed out, so that each surface of the workpiece placed in the placement slot can be sandblasted.

[0030] Furthermore, it also includes a loading structure 7 and a unloading structure 8. The loading structure 7 is disposed between the first translation mechanism 1 and the conveying mechanism, and the unloading structure 8 is disposed between the second translation mechanism 2 and the conveying mechanism. The loading structure 7 is close to the first translation mechanism 1 and needs to be accessible to the first robotic arm 3, while the unloading structure 8 is close to the second translation mechanism 2 and needs to be accessible to the second robotic arm 4. Optionally, in this embodiment, both the loading structure 7 and the unloading structure 8 include a base plate 781 and a plurality of columns 782, with the columns 782 disposed on the base plate 781. Preferably, the base plate 781 is provided with a height-adjustable placement plate 783, and the columns 782 are disposed around the placement plate 783. The parts to be sandblasted are stacked on the placement plate 783. For example, in one embodiment, the bottom of the placement plate 783 can be driven to connect to a lifting drive (not shown in the figure). The lifting drive is mounted on the base plate 781 and drives the placement plate 783 to rise and fall, thereby adjusting the height of the placement plate 783. The control system is electrically connected to the lifting drive and adjusts the height of the gripped workpiece to be sandblasted by controlling the rise and fall of the placement plate 783. The column 782 is used to limit the position of the workpiece to be sandblasted. Optionally, the lifting drive can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. The control system is also electrically connected to the first robotic arm 3 and the second robotic arm 4 to control their movements. Optionally, the control system can be a PLC.

[0031] Optionally, in this embodiment, a plurality of feeding structures 7 are provided near the first translation mechanism 1 for the first robotic arm 3 to grip and feed the workpiece to be sandblasted, and a plurality of unloading structures 8 are provided near the second translation mechanism 2 for the second robotic arm 4 to grip and unload the workpiece to be sandblasted. Optionally, for example, in this embodiment, such as... Figure 1 As shown, there are two feeding structures 7 and two unloading structures 8. Of course, there can also be one, three or more.

[0032] A sandblasting machine 6 is a mechanical device that uses compressed air to propel abrasive materials (metallic and non-metallic) onto the surface of a workpiece. The sandblasting machine 6 utilizes compressed air to transport powdery particles (1-4 mm in diameter) from one location to another within a pipeline. During this process, kinetic energy is converted into potential energy, causing the high-speed moving sand particles to scour the surface of the object, thereby improving its surface quality. Optionally, the sandblasting machine 6 is existing technology and will not be elaborated upon here.

[0033] This utility model provides an automated sandblasting production line. In use, the workpiece to be sandblasted is placed on the feeding structure 7. The control system controls the first robotic arm 3 to grab the workpiece from the feeding structure 7 and transfer it to the conveying mechanism 5 via the first translation mechanism 1. The first robotic arm 3 is then released, allowing the workpiece to fall onto the conveying mechanism 5. The conveying mechanism 5 then transports the workpiece to the sandblasting machine 6, where it performs sandblasting. The conveying mechanism 5 then transports the finished workpiece to the unloading mechanism 8. Finally, the control system controls the second robotic arm 4 to grab the workpiece from the unloading structure 8 to unload it. Specifically, the first robotic arm 3 and the second robotic arm 4 grab the workpiece from their respective placement plates 783. The first translation mechanism 1 transfers the workpiece into the placement slot on the conveying mechanism 5.

[0034] This utility model provides an automated sandblasting production line that enables automated sandblasting of parts to be sandblasted, such as power module heat dissipation substrates. This not only saves labor costs and improves production efficiency, but also allows for effective control of the sandblasting process.

[0035] The technical features of the above 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.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
