Description

Technical Field

[0001] This utility model relates to the field of crystal growth furnace production technology, and more specifically, to a visual equipment support frame for the observation port of a crystal growth furnace. Background Technology

[0002] In the process of monocrystalline silicon production, vision equipment needs to be installed at the flange observation port of the furnace to observe and acquire images of the scene inside the furnace. For most companies, the same furnace will always use a guide tube of the same diameter and the furnace depth is also a fixed depth, so the camera can be adjusted to a fixed position to work.

[0003] However, some companies are currently developing furnaces suitable for producing various types of single crystals. This includes not only the lattice form of the single crystal but also its size. This results in different flow guides and furnace depths being used in the same furnace for different types of products. This indirectly leads to variations in the image characteristics within the furnace, necessitating adjustments to the camera position to find the appropriate location for image acquisition. The main reason is that different flow guide sizes cause changes in the position and size of the flow guide obstructing the field of view in the image. Changes in furnace depth, especially with fixed focus (industrial cameras use fixed-focus lenses), will result in blurry images or objects not appearing in the field of view when captured at the previous camera height. Therefore, fixed-focus lenses must be manually adjusted to capture images with a suitable field of view, highlighting the urgent need for a visual equipment support frame for the observation port of crystal growth furnaces.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, the purpose of this utility model is to propose a vision equipment support frame for the observation port of a crystal growth furnace, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] A visual equipment support frame for the observation port of a crystal growth furnace includes: a rotating bracket movably connected to the flange observation port; a support base movably connected to the end of the rotating bracket; a guide rail fixedly connected to the support base; and a first magnetic suction base and a second magnetic suction base movably engaged within the guide rail.

[0008] An industrial camera is mounted on the top of the first magnetic base, and a filter is mounted on the top of the second magnetic base.

[0009] Furthermore, the guide rail includes a transverse rail and a longitudinal rail, wherein the transverse rail and the longitudinal rail are integrally formed.

[0010] Furthermore, the transverse track and the longitudinal track are respectively provided with sliding grooves adapted to the first magnetic base and the second magnetic base.

[0011] Furthermore, the groove includes several sets of iron sheets arranged in an array.

[0012] Furthermore, the industrial camera and the filter are adapted to each other, and a gap is provided between the industrial camera and the filter.

[0013] Furthermore, the filter is located between the industrial camera and the flange observation port.

[0014] The beneficial effects of this utility model are:

[0015] This utility model pre-adjusts the guide rail to a suitable position according to the flange observation port through the bearing seat and rotating bracket, and fixes the industrial camera and filter respectively through the first magnetic base and the second magnetic base. The first magnetic base and the second magnetic base can be adjusted to move along the guide rail to a designated position to meet the loading requirements of the industrial camera and filter. It can not only adjust the tilt, lateral distance and longitudinal distance of the industrial camera or filter at will according to production needs, but also make the adjustment simple, have high stability, and be easy to disassemble and assemble, thus meeting production needs and improving production efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, a vision device support frame for the observation port of a crystal growth furnace is provided.

[0026] like Figures 1-2 As shown, a visual equipment support frame for the observation port of a crystal growth furnace includes: a rotating bracket 2 movably connected to the flange observation port 8, a support seat 1 movably connected to the end of the rotating bracket 2, a guide rail 3 fixedly connected to the support seat 1, and a first magnetic suction base 4 and a second magnetic suction base 5 movably engaged in the guide rail 3, wherein;

[0027] An industrial camera 6 is mounted on the top of the first magnetic base 4, and a filter 7 is mounted on the top of the second magnetic base 5.

[0028] The industrial camera 6 and the filter 7 are adapted to each other, and there is a gap between the industrial camera 6 and the filter 7.

[0029] The filter 7 is located between the industrial camera 6 and the flange observation port 8.

[0030] This technical solution pre-adjusts the guide rail 3 to a suitable position using the bearing seat 1 and rotating bracket 2 according to the flange observation port 8. The industrial camera 6 and filter 7 are fixed by the first magnetic base 4 and the second magnetic base 5 respectively. The first magnetic base 4 and the second magnetic base 5 are adjusted to move along the guide rail 3 to a designated position to meet the loading requirements of the industrial camera 6 and filter 7. It can not only adjust the tilt, lateral distance and longitudinal distance of the industrial camera 6 or filter 7 at will according to production needs, but also has simple adjustment, high stability, and easy disassembly and assembly, thus meeting production needs and improving production efficiency.

[0031] In addition, when applying the above-mentioned filter 7, the brightness inside the furnace is very high during production. A special coated filter is often used to filter the light because it is corrosion resistant and can adjust the light transmittance. Generally, indium gallium tin oxide (ITO) is used, but this material is expensive. Normally, a filter of the same size is directly installed on the flange observation port.

[0032] The present invention uses a second magnetic base 5 to assemble a filter 7 which moves along the guide rail 3 to a designated position. The position of the filter 7 can be adjusted according to the position of the industrial camera 6, saving material costs, while also having high flexibility and adaptability.

[0033] Specifically, in application, most medium and large enterprises start with white furnace bodies, and a coated filter the size of a flange window is relatively expensive. However, this invention can save a lot of material costs and is highly adjustable.

[0034] Additionally, the guide rail 3 includes a transverse rail 31 and a longitudinal rail 32, which are integrally formed. The transverse rail 31 and the longitudinal rail 32 are respectively provided with grooves 33 adapted to the first magnetic base 4 and the second magnetic base 5. Each groove 33 includes several arrayed iron sheets 34.

[0035] This technical solution uses a guide rail 3 with a transverse track 31 and a longitudinal track 32 integrally formed, which respectively allows the industrial camera 6 or the filter 7 to move to a designated position along the guide rail 3, and is fixed by the first magnetic base 4 or the second magnetic base 5 in conjunction with the iron sheet 34, so as to meet the actual production loading requirements and achieve high loading stability.

[0036] In summary, the following effects can be achieved by using the above-mentioned technical solution of this utility model: the guide rail 3 is pre-adjusted to a suitable position according to the flange observation port 8 through the bearing seat 1 and the rotating bracket 2, and the industrial camera 6 and the filter 7 are fixed by the first magnetic base 4 and the second magnetic base 5 respectively. The first magnetic base 4 and the second magnetic base 5 are adjusted to move along the guide rail 3 to a designated position to meet the loading requirements of the industrial camera 6 and the filter 7. Not only can the tilt, lateral distance and longitudinal distance of the industrial camera 6 or the filter 7 be adjusted at will according to production needs, but the adjustment is also simple, the stability is high, the disassembly and assembly are simple, the production needs are met, and the production efficiency is improved.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
