[0034] See also Figure 2 A groove 11 is provided on the base 10 , and a cold plate supporting portion 12 is provided in the groove 11 .

[0035] See also Figure 3 A clamping portion 21 is provided on the movable pressing plate 20. The movable pressing plate 20 closes or opens the opening of the groove 11 under the drive of the clamping assembly 30. When the movable pressing plate 20 closes the groove 11, the movable pressing plate 20 and the groove 11 surround to form a vacuum detection cavity, and the clamping portion 21 is located in the vacuum detection cavity.

[0036] See also Figure 4 and Figure 5, multiple workpiece connection components 40 are arranged in the groove 11 and arranged on at least one side of the cold plate support part 12. The workpiece connection component 40 includes a support seat 41, a workpiece 50 connection head 42 and a first translation drive module 43. The support seat 41 is arranged in the groove 11 and arranged on the side of the cold plate support part 12. The workpiece 50 connection head 42 is arranged on one side of the support seat 41 and approaches or moves away from the support seat 41 under the drive of the first translation drive module 43.

[0037] The workpiece 50 is placed on the cold plate support part 12 in the groove 11. Multiple interfaces of the workpiece 50 are located on the side of the workpiece 50. When the workpiece 50 is placed on the cold plate support part 12, the interfaces are correspondingly located between the support seat 41 and the workpiece 50 connector 42. The clamping assembly 30 drives the movable pressure plate 20 to press against the base 10, thereby forming a vacuum detection chamber, and the clamping part 21 presses the workpiece 50 against the cold plate support part 12 to achieve clamping and fixing of the workpiece 50; then the first translation drive module 43 drives the workpiece 50 connector 42 to press against the interface of the workpiece 50 to achieve connection with the workpiece 50. The vacuum detection chamber and the workpiece 50 connector 42 are both connected to the evacuation device, and the workpiece 50 connector 42 is also connected to the detection gas filling device. The vacuum detection chamber is connected to the leak detector. During detection, the evacuation device evacuates the workpiece 50 and the vacuum detection chamber. After evacuating to a predetermined pressure, the evacuation of the workpiece 50 is stopped while the vacuum detection chamber is continued to be evacuated. Then the leak detector is turned on, and then the detection gas is filled into the workpiece 50. The leak detector is used to detect whether there is detection gas leaked from the workpiece 50 in the vacuum detection chamber, thereby determining whether there is a leak in the workpiece 50.

[0038] In some optional embodiments, a cold plate positioning space 13 is formed between the cold plate support portion 12 and the base 10 , and the cold plate positioning space 13 is used to position the workpiece 50 . After the workpiece 50 is placed in the cold plate positioning space 13 , the workpiece 50 is not easily displaced.

[0039] In some optional embodiments, a positioning column 14 for positioning and cooperating with the workpiece 50 is provided on the cold plate support portion 12. When the workpiece 50 is placed on the cold plate support portion 12, the positioning column 14 extends into a hole on the workpiece 50 to achieve positioning and cooperating with the workpiece 50.

[0040] In some optional embodiments, a plurality of workpiece connection assemblies 40 are evenly arranged on opposite sides of the cold plate support portion 12 , so as to adapt to connecting interfaces on both sides of the workpiece 50 .

[0041] In some optional embodiments, a positioning groove 44 for positioning and cooperating with the workpiece 50 is provided on the support seat 41. When the workpiece 50 is placed on the cold plate support portion 12, the protruding interface on the side of the workpiece 50 will be arranged in the positioning groove 44, and the workpiece 50 connecting head 42 will press the interface of the workpiece 50 against the inner wall of the positioning groove 44 to improve the clamping stability.

[0042] In some optional embodiments, a plurality of guide slopes 45 are formed at the top of the positioning groove 44, and the guide slopes 45 gradually approach the positioning groove 44 from top to bottom. When the workpiece 50 is placed on the cold plate support portion 12, the guide slopes 45 guide the interface into the positioning groove 44, thereby reducing collision and jamming of the workpiece 50.

[0043] The specific structure of the clamping assembly 30 can be designed according to actual needs. For example, in some optional embodiments, the clamping assembly 30 includes a support plate 31 and a lifting drive module 32.

[0045] In some optional embodiments, the clamping assembly 30 further includes a support frame 35 and a third translation drive module. The support frame 35 is provided with a guide rail 36. The support plate 31 is slidably matched with the guide rail 36. The third translation drive module (not shown) is drivingly connected to the support frame 35. The support frame 35 is driven to approach or move away from the base 10 by the third translation drive module. The third translation drive module drives the movable pressing plate 20 away from the base 10, so as to prevent the movable pressing plate 20 from interfering with the workpiece 50 being placed in the groove 11 of the base 10. After the workpiece 50 is placed in the groove 11 of the base 10, the support frame 35 is driven by the third translation drive module to move to the top of the base 10, and then the movable pressing plate 20 can be pressed down on the base 10.

[0046] The specific structures of the first translation drive module 43, the second translation drive module 34 and the third translation drive module can be designed according to actual needs. For example, the first translation drive module 43, the second translation drive module 34 and the third translation drive module can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module or a linear motor translation drive module.
