Description

TECHNICAL FIELD

[0001] The utility model relates to a workpiece cavity leak detection mechanism capable of detecting the sealing state of the cavity of a workpiece. BACKGROUND

[0002] During the operation of a computer or a server, the processor generates high temperature, and the high temperature affects the operation efficiency of the processor. Therefore, a heat dissipation module is installed on the processor of the computer or the server to contact the processor for heat exchange, so as to improve the heat dissipation capacity of the processor.

[0003] The heat dissipation module includes a heat conduction workpiece, such as a heat pipe or a uniform temperature plate. The heat conduction workpiece is made of metal, and has a sealed cavity inside. The cavity contains fluid, and the inner wall of the cavity is provided with wicking material that ensures the uniform distribution of the fluid in the cavity. The heat conduction workpiece can contact the processor, and the high temperature of the processor causes the fluid in the cavity to heat up and generate convection, thereby taking the high temperature of the processor away from the processor and dissipating heat.

[0004] To ensure the heat conduction effect of the heat conduction workpiece, the cavity of the heat conduction workpiece must be in a micro-vacuum state. During the manufacturing process of the heat conduction workpiece, the fluid and wicking material are first loaded into the cavity, and then the air in the cavity is extracted to make the cavity in a micro-vacuum state. If the wall of the cavity is damaged, the cavity cannot be vacuumed, and the fluid will leak. If the damage to the wall of the cavity is found during the air extraction process, the fluid and wicking material loaded into the cavity will be discarded together, resulting in the loss of excess materials and increased costs.

Workpiece A can be carried in the groove 22 on the bearing plate 21. When workpiece A is carried in the groove 22 on the bearing plate 21, the figure code B of workpiece A faces the outside of bearing box 20. According to different kinds of workpiece A, the position of groove 22 on bearing plate 21 is different, so that when workpiece A is installed in groove 22, suction port C is at the same height position on x axis, y axis and z axis. Users can replace the bearing plate 21 of bearing box 20 according to the type of workpiece A. Positioning hole 23 is formed through the bottom of bearing box 20, and the embodiment includes two positioning holes 23, but not limited to.

In the embodiment, the sensing assembly 30 is a code scanner, but not limited to.

[0042] Please refer to Figures 1 to 3 、 Figure 8 、 Figure 11The carrier box 20 is detachably disposed on the base plate 40, and the base plate 40 has a plurality of positioning posts 41. The positioning posts 41 protrude upward, and the number and positions of the positioning posts 41 correspond to the number and positions of the positioning holes 23, i.e. two positioning posts 41 are included in the embodiment. The cover 50 has an opening 51, and the base plate 40 and the cover 50 can move relative to each other. In the embodiment, the driving member 60 is connected to the base plate 40 and can move the base plate 40 to be sealingly attached to the cover 50 or can move the base plate 40 away from the cover 50. When the base plate 40 is attached to the cover 50, the side edges of the base plate 40 are sealingly attached to the inner edges of the opening 51, and the carrier box 20 is located in the cover 50. When the base plate 40 is moved away from the cover 50, the carrier box 20 is separated from the cover 50 and can be separated from the base plate 40.

[0043] Please refer to Figures 1 to 3 The air extraction detection mechanism 70 has a leak detector 71 and an air extraction pipe 72. The leak detector 71 can extract air in the cavity of the workpiece A for detection. The air extraction pipe 72 is disposed in the cover 50 and is used to connect the workpiece A and the leak detector 71. The air extraction pipe 72 is disposed in the cover 50 at a position such that the air extraction pipe 72 can be connected to the workpiece A when the cover 50 is sealingly attached to the base plate 40. The air extraction detection mechanism 70 can extract air in the cavity of the workpiece A and detect the change in the content of a specific gas in the extracted air, thereby determining whether the cavity of the workpiece A is sealed.

When the base plate 40 is sealingly attached to the cover 50, the air extraction pipe 72 of the air extraction detection mechanism 70 is connected to the workpiece A at the same time, and then the air jet nozzle 10 sprays a specific gas (e.g. helium), so that the specific gas fills in the cover 50. At this time, since the workpiece A is not filled with other gas in advance, the cavity of the workpiece A is filled with air, and the outside of the cavity of the workpiece A is filled with the specific gas. Then, the air extraction detection mechanism 70 extracts air from the cavity of the workpiece A and detects the content of the specific gas in the air. If the content of the specific gas does not change, it means that the cavity of the workpiece A is in a sealed state. If the content of the specific gas increases, it means that the cavity of the workpiece A has a leak, i.e. the workpiece A is a defective product.

[0045] The utility model discloses the advantage lies in, through the air -extraction detection mechanism 70 draws the cavity of work piece A's air, and detects the content of specific gas in the air, can further judge whether the cavity of work piece A exists the loophole. If work piece cavity leak detection mechanism is placed before filling the fluid and the process of wicking material, can avoid the fluid and wicking material in bad work piece A to be wasted, and then reduce the manufacturing cost.
