[0033] See also Figure 3 The cold plate clamp device 20 is arranged on the frame 10, and a vacuum detection chamber is arranged on the cold plate clamp device 20. A plurality of workpiece connecting components 21 are arranged in the vacuum detection chamber, and the workpiece connecting component 21 is used to be connected with the interface of the workpiece 70. The dust removal mechanism 30 is correspondingly arranged on one side of the cold plate clamp device 20, the vacuum device 40 is respectively connected with the vacuum detection chamber and the workpiece connecting component 21, the leak detector 50 is connected with the vacuum detection chamber, and the detection gas filling device is connected with the workpiece connecting component 21.

[0034] The workpiece 70 is placed in the vacuum detection chamber, and multiple interfaces of the workpiece 70 are correspondingly connected to the workpiece connecting assembly 21. During detection, the evacuation device 40 evacuates the workpiece 70 and the vacuum detection chamber. After evacuating to a predetermined pressure, the evacuation of the workpiece 70 is stopped while the vacuum detection chamber is continued to be evacuated. Then the leak detector 50 is turned on, and then the detection gas filling device fills the inside of the workpiece 70 with detection gas. The leak detector 50 is used to detect whether there is detection gas leaked from the workpiece 70 in the vacuum detection chamber, so as to determine whether there is a leak in the workpiece 70.

[0035] By clamping a plurality of workpieces 70 through a plurality of cold plate fixture devices 20 , vacuum detection can be performed on the plurality of workpieces 70 at the same time, thereby improving detection efficiency and accelerating production cycle.

[0036] See also Figure 4 The specific structure of the dust removal mechanism 30 can be designed according to actual needs. For example, in some optional embodiments, a plurality of movable guide rails 11 are arranged on the frame 10. The dust removal mechanism 30 includes a movable frame 31, a first translation driving module 32 and a dust removal air outlet 33. The movable frame 31 corresponds to the movable guide rail 11 for sliding cooperation, and moves back and forth above the cold plate clamp device 20 along the movable guide rail 11 under the drive of the first translation driving module 32. The dust removal air outlet 33 is arranged at the bottom of the movable frame 31 and faces the cold plate clamp device 20. The wind blown out of the dust removal air outlet 33 removes dust from the workpiece 70. The first translation driving module 32 drives the movable frame 31 to move back and forth so that the dust removal air outlet 33 can remove dust from different positions of the workpiece 70.

[0037] In some optional embodiments, a plurality of dust removal vents 33 are provided at the bottom of the movable frame 31 , and the plurality of dust removal vents 33 are arranged in sequence along a direction perpendicular to the movable guide rail 11 , thereby achieving a better dust removal effect and fewer dead angles.

[0038] In some optional embodiments, the dust removal mechanism 30 also includes a lifting frame 34 and a lifting drive module 35. The lifting frame 34 is arranged at the bottom of the movable frame 31, and is lifted and lowered relative to the movable frame 31 under the drive of the lifting drive module 35.

The lifting frame 34 is lifted and lowered by the lifting drive module 35, so that the dust removal air outlet 33 is close to or away from the cold plate clamp device 20. When the workpiece 70 needs to be dusted, the lifting drive module 35 drives the lifting frame 34 to descend to approach the cold plate clamp device 20.

[0039] In some optional embodiments, the lifting frame 34 is slidably matched with the movable frame 31 through a plurality of guide rods 36 , thereby improving the lifting stability of the lifting frame 34 .

When the movable pressure plate 24 closes the groove 26, the movable pressure plate 24 and the groove 26 surround to form a vacuum detection chamber, and the movable pressure plate 24 presses the workpiece 70 into the groove 26, thereby clamping the workpiece 70 to achieve clamping and fixing of the workpiece 70.

[0043] See also Figure 6 In some optional embodiments, the workpiece connection assembly 21 includes a support seat 211, a workpiece connection head 212 and a second translation drive module 213. The support seat 211 is disposed in the groove 26 and arranged on the side of the cold plate support portion 27. The workpiece connection head 212 is disposed on one side of the support seat 211 and is driven by the second translation drive module 213 to approach or move away from the support seat 211, so that the workpiece connection head 212 is pressed against the interface of the workpiece 70 to achieve a stable connection with good sealing. The workpiece connection head 212 is connected to the evacuation device 40, the leak detector 50 and the gas recovery device 60.

[0044] In some optional embodiments, the support frame 23 is slidably matched with the movable guide rail 11 provided on the frame 10, and is driven by the third translation drive module 28 to move closer to or away from the base 22 along the movable guide rail 11, thereby conveniently driving the support frame 23 to avoid the base 22, and preventing the support frame 23 from obstructing the workpiece 70 from being placed in the groove 26 of the base 22. In addition, both the support frame 23 and the movable frame 31 are slidably matched with the movable guide rail 11, which is conducive to simplifying the structure.

For example, the first translation drive module 32, the second translation drive module 213, the third translation drive module 28 and the lifting drive module 35 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. In this embodiment, the first translation drive module 32, the second translation drive module 213, the third translation drive module 28 and the lifting drive module 35 adopt a cylinder translation drive module.
