Description

Technical Field

[0001] This utility model relates to the field of constant temperature tables, specifically to a constant temperature table. Background Technology

[0002] A temperature-controlled stage is a laboratory or industrial equipment platform that maintains a stable specific temperature. Through a precise temperature control system, it ensures that the platform or working area is in a constant temperature environment. Its core function is to eliminate temperature fluctuations and provide a stable thermal environment for experiments, production, or testing.

[0003] However, existing constant temperature stages have the following drawbacks:

[0004] When the temperature control stage is not in use, it cannot prevent the top surface of the temperature control stage from becoming contaminated; the top surface of the temperature control stage cannot be automatically cleaned before the sample is placed on it, thus preventing the debris attached to the top surface of the temperature control stage from hindering the heat conduction of the temperature control stage to the sample. This can easily lead to a decrease in the heating efficiency of the sample after it is placed on the temperature control stage, and can easily lead to the inability of samples that require rapid heating to be heated rapidly.

[0005] The purpose of this invention is to design a constant temperature stage to address the problems existing in the prior art. Utility Model Content

[0006] In view of the problems existing in the prior art, the present invention provides a constant temperature stage that can effectively solve at least one of the problems existing in the prior art.

[0007] The technical solution of this utility model is:

[0008] A temperature-controlled stage, comprising:

[0009] A base, the top surface of which is provided with a receiving groove, and a sample stage and a heating element are arranged sequentially from top to bottom on the base and within the receiving groove, and a temperature sensor is arranged between the heating element and the sample stage;

[0010] A shield is rotatably provided on the top surface of the base, a transverse frame is laterally moved inside the shield, a cleaning layer is longitudinally provided on the bottom surface of the transverse frame, and a transverse drive component is provided between the shield and the transverse frame.

[0011] The transverse frame is used to move laterally to a predetermined position in front of the sample stage after the shielding cover covers the sample stage and the sample is placed on the sample stage, so as to drive the cleaning layer to clean the top surface of the sample stage laterally.

[0012] Furthermore, a water-cooling component is provided between the base and the bottom surface of the heating element.

[0013] Furthermore, the water-cooled component includes a water-cooled base disposed between the base and the bottom end face of the heating element. A water-cooled groove is provided on the bottom end face of the water-cooled base, and a sealing cover is provided on the bottom end face of the water-cooled base below the water-cooled groove. An inlet pipe and an outlet pipe communicating with the water-cooled groove are provided on the water-cooled base. A water-cooled box is provided on one side of the base. The inlet pipe and the outlet pipe both extend out of the base and communicate with the water-cooled box. A liquid pump is provided on the inlet pipe.

[0014] Furthermore, the water-cooling tank includes an S-shaped groove disposed on the bottom end face of the water-cooling base. The bottom end face of the water-cooling base is provided with a plurality of surface-enhancing grooves that communicate with the S-shaped groove. The plurality of surface-enhancing grooves are staggered on both sides of the S-shaped groove.

[0015] Furthermore, a heat insulation device is provided at the connection between the sample stage and the base.

[0016] Furthermore, the heat insulation device is a silicone paper layer, which is disposed at the connection between the sample stage and the base.

[0017] Furthermore, the lateral movement drive includes a lead screw, which is laterally arranged inside the shielding cover. A linkage block is provided between the lead screw and the lateral movement frame. A rotating motor is connected between the shielding cover and the lead screw.

[0021] 1) The sample stage is used for placing the sample, and the shield is used to shield the sample stage before the sample is placed on it, thereby preventing the top surface of the sample stage from being contaminated when the temperature-controlled stage is not in use.

[0022] The transverse frame is used to move laterally to a predetermined position before the sample stage is shielded by the shielding cover and the sample is placed on the sample stage, so as to drive the cleaning layer to clean the top surface of the sample stage laterally. This can prevent the debris attached to the top surface of the sample stage from hindering the heat conduction of the sample stage to the sample, and will not reduce the heating efficiency of the sample after the sample is placed on the sample stage, and will not prevent the sample that needs to be heated quickly from being unable to be heated quickly.

The shield is driven to rotate to a predetermined angle when the sample is placed on the sample stage. The heating element is energized and heated to a predetermined temperature after the sample is placed on the sample stage. The sample stage is used to conduct the heat generated by the heating element to the sample. The temperature sensor is used to monitor the temperature of the surrounding environment when the heating element is energized and heating.

[0024] In summary: it can prevent contamination of the top surface of the temperature control stage when it is not in use; it can automatically clean the top surface of the temperature control stage before the sample is placed on it, thereby preventing debris on the top surface of the temperature control stage from hindering the heat conduction of the sample to the temperature control stage, and preventing a decrease in the heating efficiency of the sample after it is placed on the temperature control stage, and ensuring that samples that require rapid heating can be heated rapidly.

[0025] 2) The water-cooling component is used to cool the heating element when the temperature sensor detects that the ambient temperature exceeds a predetermined value, so as to prevent the constant temperature stage from overheating and being damaged.

[0026] 3) The heat insulation device is used to reduce the heat generated by the heating element from escaping from the connection between the sample stage and the base during the heating element's power-on heating period.

[0027] 3) The cleaning layer can be attached and detached from the transverse frame, allowing for regular maintenance or replacement of the cleaning layer to ensure its effectiveness in cleaning the top surface of the sample stage.
