Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a compact sensor bracket for vacuum equipment. Background Technology

[0002] In vacuum equipment, to enable the automated system to determine the presence or absence of objects inside the vacuum chamber, a penetrating laser sensor is typically used after an opening is made in the vacuum chamber and pressure-resistant and explosion-proof glass is installed. This sensor adapts to the working conditions and isolating the air pressure. To ensure long-term stability when the laser of the sensor penetrates the small hole, a corresponding sensor mounting bracket is required.

[0003] For example, Chinese patent application number CN 202321265048.6 discloses a sensor mounting bracket, including a bracket body with a mounting surface for placing a sensor. At least two anti-crack grooves are formed at one end of the bracket body. The portion of the bracket body between adjacent anti-crack grooves is bent in a direction protruding from the mounting surface to form a support block. When the sensor is located on the mounting surface, its end rests on the support block, preventing stress concentration and ensuring the overall strength and reliability of the bracket. However, this bracket body is relatively large, making installation and adjustment difficult in the confined spaces of vacuum equipment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a compact sensor bracket for vacuum equipment, so as to solve the technical problem that the bracket body is large in size and difficult to install and adjust in the confined working conditions of vacuum equipment.

[0005] To achieve the above objectives, this utility model provides a compact sensor bracket for a vacuum device, comprising a bracket body mounted on the vacuum device. The bracket body includes a mounting portion and a cantilever portion, the cantilever portion being connected to the mounting portion and connected to the cavity wall of the vacuum device via the mounting portion. The mounting portion has a clearance area. The sensor bracket further includes: An opening mounting base is provided on a vacuum device, wherein the opening in the middle of the opening mounting base corresponds to the pressure-resistant and explosion-proof glass at the opening of the vacuum device cavity, and the cross-sectional area of ​​the opening mounting base is smaller than the area of ​​the avoidance area. A sensor mounting base is provided on the cantilever to support the sensor and is directly opposite the central opening of the opening fixing base; An adjustment section is provided on the cantilever to adjust and lock the spatial angle of the sensor mounting base.

[0006] Furthermore, the mounting part is flat and has mounting holes that penetrate its thickness. The mounting holes are used to fix the bracket body to the cavity wall of the vacuum equipment using fasteners.

[0007] Furthermore, the head of the fastener does not protrude from the opening fixing seat.

[0008] Furthermore, the cantilever section has a Z-shaped bend structure, and all bends are at right angles.

[0009] Furthermore, the sensor mounting base is provided with threaded holes for fixing the sensor.

[0010] Furthermore, the adjustment part includes a fixing hole and an arc-shaped hole provided on the cantilever part, and the movement of the sensor mounting base is centered on the fixing hole and the degree of rotation is centered on the arc of the arc-shaped hole.

[0011] Furthermore, the cantilever section is provided with multiple weight-reducing holes.

[0012] Furthermore, the support body is made of aluminum alloy.

[0013] The beneficial effects of this utility model are as follows: In use, the combined installation part and cantilever part, together with the relatively independent opening fixing seat, can be accommodated in the clearance area, which greatly reduces the space occupied by the entire bracket on the outer wall of the vacuum equipment. It is perfectly adapted to the working conditions of the narrow external space of the vacuum equipment. The sensor mounting seat set on the cantilever part can be accurately aligned with the pressure-resistant and explosion-proof glass inlaid in the center of the opening fixing seat, providing a stable and unobstructed optical path for the sensor laser beam plug and signal reception. Under the adjustment and locking of the adjustment part, the accuracy and long-term stability of the detection are guaranteed. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0018] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0019] The first aspect of this utility model proposes a compact sensor holder for a vacuum device, such as... Figure 1-3 As shown, the sensor bracket includes a support body mounted on a vacuum device. The support body includes a mounting portion 1 and a cantilever portion 2. The cantilever portion 2 is connected to the mounting portion 1 and is connected to the cavity wall of the vacuum device through the mounting portion 1. The mounting portion 1 is provided with a clearance area 3. The sensor bracket also includes: The opening of the opening fixing seat 4 on the vacuum equipment corresponds to the pressure-resistant and explosion-proof glass at the opening of the vacuum equipment cavity. The cross-sectional area of ​​the opening fixing seat 4 is smaller than the area of ​​the avoidance area 3. A sensor mounting base 5 is provided on the cantilever 2 to support the sensor and is directly opposite the central opening of the opening fixing base 4; An adjustment section is provided on the cantilever 2 for adjusting and locking the spatial angle of the sensor mounting base 5.

[0020] In this embodiment, the combined installation part 1 and cantilever part 2, along with the relatively independent opening fixing seat 4, can be accommodated within the clearance area 3, greatly reducing the space occupied by the entire bracket on the outer wall of the vacuum equipment. This perfectly adapts to the working conditions of the confined external space of the vacuum equipment. The sensor mounting seat 5 provided on the cantilever part 2 can be precisely aligned with the pressure-resistant and explosion-proof glass embedded in the opening in the middle of the opening fixing seat 4, providing a stable and unobstructed optical path for the sensor laser beam plug and signal reception. Under the adjustment and locking of the adjustment part, the accuracy and long-term stability of the detection are guaranteed.

[0021] In this embodiment, as Figure 3As shown, the mounting part 1 is flat and has a mounting hole 6 that penetrates its thickness. The mounting hole 6 is used to fix the bracket body to the cavity wall of the vacuum equipment by fasteners.

[0022] In this embodiment, as Figure 1 As shown, the head of the fastener does not protrude from the opening fixing seat 4, and the cantilever part 2 has a Z-shaped bending structure, and all of them are right-angle bends, so that the sensor mounting seat 5 can extend outward from the mounting fixing point and cleverly avoid other protruding parts on the vacuum equipment housing, and finally position the sensor in a position directly opposite the cavity opening.

[0023] In this embodiment, as Figure 1 As shown, the sensor mounting base 5 has threaded holes 7 for fixing the sensor. Operators only need to use tools to tighten the screws to fix the sensor. Disassembly is also convenient, which greatly improves the efficiency of installation and maintenance.

[0024] In this embodiment, as Figure 3 As shown, the adjustment unit includes a fixing hole 8 and an arc-shaped hole 9 on the cantilever part 2. The movement of the sensor mounting base 5 is centered on the fixing hole 8 and the degree of rotation is determined by the arc length of the arc-shaped hole 9. During installation, one fastener passes through the sensor mounting base 5 and is screwed into the fixing hole 8, but is not completely locked, serving as the rotation axis. The other fastener passes through the sensor mounting base 5 and slides within the range of the arc-shaped hole 9. When the laser deflection is caused by long-term vibration of the equipment and the angle needs to be adjusted, the two fasteners are loosened, and the sensor mounting base 5 can rotate with the fixing hole 8 as the center. Its rotation range is limited by the arc length of the arc-shaped hole 9. After adjusting to the optimal angle, the fasteners are tightened to fix the spatial angle of the sensor mounting base 5, ensuring that the laser beam can pass through the center of the pressure-resistant and explosion-proof glass vertically and accurately.

[0025] In this embodiment, as Figure 3 As shown, the cantilever 2 is provided with multiple weight-reducing holes 10, which reduces the load on the vacuum equipment support structure and also helps to reduce the amount of material used.

[0026] In this embodiment, the support body is made of aluminum alloy, which provides sufficient structural strength while having a density much lower than that of steel, thus achieving lightweighting.
