[0013] Figure 1 This is a schematic diagram of the front structure of the intelligent leakage detection device in this embodiment (without the outer shell);

[0014] Figure 2 It is a schematic diagram of the three-dimensional structure of the intelligent leakage detection device in this embodiment.

[0015] The realization of the purpose of the present invention and its functions and principles will be further explained in the specific implementation manner in conjunction with the accompanying drawings. DETAILED DESCRIPTION

[0016] The following is a further description with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 As shown, this embodiment provides an intelligent leak detection device 100, including a frame 10, a first inspection table 20 arranged on the frame 10, a vacuum cover assembly 30 and a helium mass spectrometer detection host 40. The frame 10 is a three-layer structure, the vacuum cover assembly 30 is located at the upper layer, the first inspection table 20 is located at the middle layer, and the helium mass spectrometer detection host 40 is located at the lower layer. There are two first inspection tables 20, which are distributed on the left and right sides of the frame 10 and work in turns. The vacuum cover assembly 30 includes two vacuum covers 31 and a bracket 32 ​​for driving the two vacuum covers 31 in linkage. The vacuum covers 31 are suitable for being covered on the first inspection table 20 when the corresponding first inspection table 20 is working; the helium mass spectrometer detection host 40 is respectively connected to the two vacuum covers 31 and detects the helium in the vacuum covers 31; and also includes a helium supply system 50, which further includes a helium tank 51, a pipe and a gas 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 cover assembly 30 is composed of a sprocket 33 fixed to the top of the frame through the bracket 32, a chain 34 passing through the sprocket 33 and connected to a vacuum cover 31 at both ends, a driving mechanism 35 driving the sprocket 33 to rotate so that the vacuum cover 31 moves up and down, and two vacuum covers 31. The driving mechanism 35 is suitable for driving the corresponding vacuum cover 31 to move according to the working sequence of the first inspection station 20. That is, when one of the first inspection stations 20 needs to be loaded or unloaded, the vacuum cover 31 corresponding to it rises under the drive of the driving mechanism 35, and the vacuum cover 31 corresponding to the other first inspection station 20 descends and covers the first inspection station 20 so that it can perform inspection work. When the other first inspection station 20 has finished its work, it needs to open the vacuum cover 31 for unloading. At this time, the current first inspection station 20 has just finished loading, and the vacuum cover 31 can be covered for inspection work..., and this alternating operation can greatly improve the inspection efficiency.

[0019] In order to further improve the working efficiency of the equipment, the present embodiment is further provided with an electric control system, which is connected to the above-mentioned first inspection station 20, vacuum cover assembly 30 and helium supply system 50, and is used to uniformly control the first inspection station 20, vacuum cover assembly 30 and helium supply system 50 so that they can work in coordination. For example, when the first inspection station 20 is loaded with materials, the electric control system controls the driving mechanism 35 to move the vacuum cover assembly 30, sets the vacuum cover 31 on the first inspection station 20 and evacuates the vacuum, and at the same time, controls the opening and closing of each gas valve of the helium supply system 50, and passes helium into the workpiece to be inspected, thereby realizing automatic inspection of the workpiece.

[0020] In order to effectively reduce the detection cost, the present embodiment is further provided with a helium recovery system 60, which is respectively connected to the first inspection station 20, and is used to recover the helium after the detection is completed, and to re-pressurize the helium for reuse using equipment such as a compression pump.

[0021] Due to equipment and site limitations, the first inspection station 20 can generally detect workpieces of one type, or different types of the same specification, and the detection range is severely limited. In order to increase the types and specifications of workpieces to be detected at a low cost and greatly expand the utilization rate of the equipment, this embodiment also provides at least one second inspection station 70 (such as Figure 2 As shown in FIG. 2 ), 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 detect workpieces whose size and specifications are larger than those of the first inspection table 20. At the same time, the second inspection table 70 is connected to the helium recovery system 60 to recycle the helium in the second inspection table 70.

[0022] In order to facilitate the loading and unloading of workpieces, a slide rail is provided under the first inspection table 20 of this embodiment. Workers can pull out the first inspection table 20 to facilitate operation while ensuring operation safety. After the operation is completed, the first inspection table 20 can be pushed into the frame 10.

[0023] In order to make the product more beautiful, this embodiment also provides a shell 80 (such as Figure 2 to close the various components.

[0024] In summary, the present invention utilizes two first inspection stations to perform inspections in turn, which not only does not occupy too much space, but also allows one of the first inspection stations to perform inspections, and the other to use the inspection time to load or unload materials, and the two inspection stations work in turn, which is highly efficient. Moreover, by adding a second inspection station, workpieces of different specifications and sizes, even oversized sizes, can be inspected, which greatly expands the utilization rate of the equipment and reduces the cost of equipment upgrades.

[0025] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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 above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
