The two inspection stations work alternately, resulting in high work efficiency. Attached Figure Description

[0013] Figure 1 This is a front view of the intelligent leak detection device in this embodiment (without the outer casing).

[0014] Figure 2 This is a three-dimensional structural diagram of the intelligent leak detection device in this embodiment.

[0015] The purpose of this utility model, as well as its functions and principles, will be further explained in conjunction with the accompanying drawings in specific embodiments. Detailed Implementation

[0016] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details.

[0017] like Figure 1 As shown, this embodiment provides an intelligent leak detection device 100, including a frame 10, a first inspection table 20 disposed on the frame 10, a vacuum hood assembly 30, and a helium mass spectrometer detection host 40. The frame 10 has a three-layer structure, with the vacuum hood assembly 30 located on the upper layer, the first inspection table 20 located on the middle layer, and the helium mass spectrometer detection host 40 located on the lower layer. There are two first inspection tables 20, arranged horizontally on the frame 10 and operating alternately. The vacuum hood assembly 30 includes two vacuum hoods 31 and a bracket 32 ​​for driving the two vacuum hoods 31 to work together. The vacuum hoods 31 are adapted to cover the first inspection table 20 when the corresponding first inspection table 20 is working. The helium mass spectrometer detection host 40 is connected to the two vacuum hoods 31 respectively and detects the helium gas in the vacuum hoods 31. It also includes a helium supply system 50, which further includes a helium tank 51, a pipe and a valve (not shown) connecting the helium tank 51 to the first inspection table 20 and the helium mass spectrometer detection host 40.

[0018] Specifically, the vacuum chamber assembly 30 consists of a sprocket 33 fixed to the top of the frame via the bracket 32, a chain 34 passing through the sprocket 33 and connected to a vacuum chamber 31 at each end, a drive mechanism 35 that drives the sprocket 33 to rotate so that the vacuum chamber 31 moves up and down, and two vacuum chambers 31. The drive mechanism 35 is adapted to drive the corresponding vacuum chamber 31 to move according to the working sequence of the first inspection table 20. That is, when one of the first inspection tables 20 needs to load or unload materials, the corresponding vacuum chamber 31 rises under the drive of the drive mechanism 35, and the vacuum chamber 31 corresponding to the other first inspection table 20 descends and covers the first inspection table 20, allowing it to perform inspection work. When the other first inspection table 20 finishes working, it needs to open the vacuum chamber 31 for unloading. At this time, the current first inspection table 20 has just finished loading materials and can close the vacuum chamber 31 for testing... This alternating process can greatly improve the testing efficiency.

[0019] To further improve the equipment's working efficiency, this embodiment also includes an electronic control system. This system is connected to the first inspection table 20, the vacuum chamber assembly 30, and the helium supply system 50, and is used to uniformly control these components, enabling them to operate in coordination. For example, when the first inspection table 20 is fully loaded, the electronic control system controls the drive mechanism 35 to activate the vacuum chamber assembly 30, placing the vacuum chamber 31 over the first inspection table 20 and creating a vacuum. Simultaneously, it controls the opening and closing of the various valves in the helium supply system 50, introducing helium into the workpiece to be inspected, thereby achieving automatic workpiece inspection.

[0020] To effectively reduce testing costs, this embodiment also includes a helium recovery system 60, which is connected to the first inspection station 20. After testing is completed, the helium is recovered and repressurized using equipment such as a compression pump for reuse.

[0021] Due to equipment and space limitations, the first inspection station 20 can generally only inspect one type of workpiece, or different types of the same specification, severely limiting its inspection range. To increase the types and specifications of workpieces that can be inspected at low cost and significantly expand equipment utilization, this embodiment also includes at least one second inspection station 70 (e.g., ...). Figure 2 As shown in the diagram, the second inspection table 70 is connected to the helium supply system 50. The second inspection table 70 is longer than the first inspection table 20, and can inspect workpieces with sizes and specifications larger than those that can be inspected by the first inspection table 20. Simultaneously, the second inspection table 70 is connected to the helium recovery system 60 to recover and reuse the helium within the second inspection table 70.

[0022] To facilitate the loading and unloading of workpieces, a slide rail is provided below the first inspection table 20 in this embodiment. The worker can pull out the first inspection table 20 for convenient operation and to ensure operational safety. After the operation is completed, the first inspection table 20 can be pushed into the frame 10.

[0023] To enhance the product's appearance, this embodiment also includes an outer casing 80 (e.g., ...) on the outside of the frame. Figure 2 (As shown), to enclose each component.

[0024] In summary, this invention utilizes two first inspection tables for alternating inspection, which not only avoids occupying excessive space but also allows for the use of one inspection table for inspection while the other is used for loading or unloading materials. The two inspection tables work alternately, resulting in high efficiency. Furthermore, by adding a second inspection table, it is possible to inspect oversized workpieces, significantly expanding equipment utilization and reducing equipment upgrade costs.

[0025] 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.

[0026] The embodiments described above are merely examples 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 modifications and improvements all fall within the protection scope of this utility model.
