Description

Technical Field

[0001] This utility model relates to the field of aluminum nitride green billet technology, and in particular to an automatic inspection device for aluminum nitride green billets. Background Technology

[0002] Aluminum nitride green bodies are semi-finished products of alumina ceramics. Thickness needs to be controlled to screen out products whose thickness does not meet the specifications. Although the aluminum nitride green bodies undergo high-pressure blowing treatment in the preliminary process, during testing, the porous surface of the aluminum nitride green body easily accommodates fine particles. This can lead to an overestimation of the thickness of the aluminum nitride green body during subsequent thickness testing due to the influence of these particles, thus affecting the accuracy of the measured structure. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where particulate matter can easily lead to excessively large thicknesses in the tested aluminum nitride green billets, affecting the accuracy of the tested structure. Therefore, an automatic inspection device for aluminum nitride green billets is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design an automatic inspection device for aluminum nitride billets, including a conveyor belt, a second fixed frame fixedly connected to the support frame of the conveyor belt, a laser sensor and a position sensor fixedly connected to the second fixed frame, a controller fixedly connected to the support frame of the conveyor belt, the controller being signal-connected to the laser sensor and the position sensor, a first fixed frame fixedly connected to one end of the support frame of the conveyor belt, and a cleaning mechanism provided on the first fixed frame.

[0005] Preferably, the cleaning mechanism includes a threaded hole, which is formed on the first fixed frame. A threaded rod is threadedly connected to the threaded hole, and a brush is connected to the threaded rod through a connecting mechanism.

[0006] Preferably, the connecting mechanism includes a fixing part, which is rotatably connected to a threaded rod via a bearing. A positioning post is fixedly connected to the fixing part. A positioning hole is provided on the first fixing frame, and the positioning post is inserted into the positioning hole. The fixing part is fixedly connected to the brush via bolts.

[0007] Preferably, the bristles of the brush are made of polyester fiber.

[0008] Preferably, a placement platform is fixedly connected to the other end of the support frame of the conveyor belt, a telescopic rod is fixedly connected to the placement platform, and a pulling block is fixedly connected to the output end of the telescopic rod.

[0009] Preferably, the telescopic rod is an electric telescopic rod, and the telescopic rod is signal-connected to the controller.

[0010] The present invention proposes an automatic inspection device for aluminum nitride green billets, which has the following advantages: by employing a cleaning mechanism to clean the aluminum nitride green billets passing through the conveyor belt, it is beneficial to remove dust from the pores of the aluminum nitride green billets, avoid the influence of dust, and thus improve the accuracy of the test results.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example 1: Refer to Figure 1-4An automatic inspection device for aluminum nitride green billets includes a conveyor belt 1, which is a plate conveyor belt. A second fixed frame 3 is fixedly connected to the support frame of the conveyor belt 1. A laser sensor 13 and a position sensor 14 are fixedly connected to the second fixed frame 3. A controller 7 is fixedly connected to the support frame of the conveyor belt 1. The controller 7 is signal-connected to the laser sensor 13 and the position sensor 14. When the position sensor 14 detects that the aluminum nitride green billet has completely entered the detection area of ​​the laser sensor 13, the laser sensor 13 is triggered to measure the distance. The laser sensor 13 measures the distance between the surface of the aluminum nitride green billet and the laser sensor 13. The straight-line distance from the laser sensor 13 to the conveyor belt 1 is fixed. The thickness of the aluminum nitride green billet can be obtained by subtracting the two values. A first fixed frame 2 is fixedly connected to one end of the support frame of the conveyor belt 1. A cleaning mechanism is provided on the first fixed frame 2. The cleaning mechanism cleans the aluminum nitride green billet passing through the conveyor belt 1, which helps to remove dust from the pores of the aluminum nitride green billet, avoids the influence of dust, and thus helps to improve the accuracy of the inspection results.

[0015] The cleaning mechanism includes a threaded hole 15, which is opened on the first fixed frame 2. A threaded rod 9 is threadedly connected to the threaded hole 15. The threaded rod 9 is connected to a brush 10 through a connecting mechanism. The brush 10 is used to clean the dust when the aluminum nitride blank comes into contact with it. At the same time, the bristles of the brush 10 are made of polyester fiber, which is soft and avoids damage to the aluminum nitride blank.

[0016] Example 2: Refer to Figure 1-4 In another preferred embodiment of this utility model, based on embodiment 1, the connecting mechanism includes a fixing part 11. The fixing part 11 is rotatably connected to the threaded rod 9 via a bearing. A positioning post 8 is fixedly connected to the fixing part 11. A positioning hole 16 is provided on the first fixing frame 2. The positioning post 8 is inserted into the positioning hole 16. By rotating the threaded rod 9, the position of the threaded rod 9 in the threaded hole 15 is adjusted so as to adjust the height of the brush 10 and to detect aluminum nitride blanks of different thicknesses. The positioning post 8 and the positioning hole 16 prevent the fixing part 11 from rotating synchronously when the threaded rod 9 rotates, thus ensuring the horizontality of the brush 10. The fixing part 11 is fixedly connected to the brush 10 via bolts 12 so as to replace the brush 10 after it is damaged.

[0017] Example 3: Reference Figure 1-2In another preferred embodiment of this utility model, based on embodiment 2, a placement platform 4 is fixedly connected to the other end of the support frame of the conveyor belt 1. A telescopic rod 5 is fixedly connected to the placement platform 4, and a pulling block 6 is fixedly connected to the output end of the telescopic rod 5. The telescopic rod 5 is an electric telescopic rod, and the telescopic rod 5 is signal-connected to the controller 7. By retracting the telescopic rod 5, the pulling block 6 is moved so as to push the unqualified aluminum nitride billets into the placement platform 4 for collection. The controller 7 can be a Siemens S7-1200 series.

[0018] During testing, the aluminum nitride billet first passes through the brush 10, which cleans the billet. When the position sensor 14 detects that the aluminum nitride billet has completely entered the detection area of ​​the laser sensor 13, the controller 7 controls the laser sensor 13 to measure the distance. When the detection result is less than or greater than the marked value, the controller 7 causes the telescopic rod 5 to retract, pushing the unqualified aluminum nitride billet onto the placement table 4 via the pull block 6.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
