Abstract
Description

[0002] Some product testing contents require temperature control of the product, and the product temperature is controlled within a certain range to facilitate the next step of testing the product. The existing technical solution is to first use a sealed box to seal the machine or test module when performing low-temperature control on the product (below zero temperature), and then use air cooling for low-temperature control. However, the use of air cooling for low-temperature control is inefficient and will produce more condensation or frost. In order to solve the problems of condensation and frost, a large-sized sealed box can also be used in conjunction with an industrial dehumidifier to control the air humidity in the sealed environment and solve the problems of condensation and frost.

It can be seen that the temperature control module 2 and the detection module 3 are both fixed on the mounting table 10 and cooperate with the sealing cover 11, the mounting table 10 and the sealing cover 11 form a closed space, the temperature control module 2 is connected to the product carrier 4 and the detection module 3 respectively, and the temperature control module 2 plays a role in controlling the ambient temperature of the product to be tested.
[0019] like Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, a water cooler 12 is provided on the installation table 10, and the water cooler 12 is connected to the temperature control module 2 through a water pipe 77. A humidity sensor 13 and an air pipe joint 14 are provided in the sealing cover 11, and the air pipe joint 14 is connected to an external device through a manual valve 15. It can be seen that the patent of this application is to cool down the product carrier 4 through the water cooler 12. At the same time, the humidity sensor 13 is provided to ensure real-time monitoring of the humidity inside the sealing cover 11, and ensure that the water cooler 12 will not produce condensation or frost when performing low-temperature treatment. The manual valve 15 plays the role of disconnecting and connecting the air pipe. The air pipe joint 14 is connected to an external device, and dry air is input into the sealing cover 11 through the external device to reduce the humidity inside the sealing cover 11 and avoid condensation or frost. The sealing cover 11 is provided with a plurality of handles, and the handles can easily lift and install the sealing seat 11, making it more convenient to disassemble and assemble the components and replace the product carrier 4 of the patent of this application.
[0020] like Figure 2 and Figure 3As shown, in this embodiment, the temperature control module 2 includes a temperature control component 20 and a temperature control base component 21, the temperature control component 20 is limitedly matched on the temperature control base component 21, the temperature control base component 21 is fixed to the installation table 10, and the product carrier 4 is limitedly matched with the temperature control component 20. It can be seen that the product carrier 4 is limitedly matched on the temperature control component 20, the temperature control component 20 is limitedly matched on the temperature control base component 21, and the temperature control base component 21 provides support and limit for the temperature control component 20.
[0021] like Figure 1 and Figure 3 As shown, in this embodiment, the water cooler 12 is provided with a quick plug 88, and the quick plug 88 is limitedly matched with the water pipe 77. It can be seen that the water cooler 12 is limitedly matched with the water pipe 77 through the quick plug 88, and the quick plug 88 can improve the efficiency of disassembly and assembly of the patent application and facilitate maintenance.
[0022] like Figure 3 and Figure 4 As shown, in this embodiment, the temperature control component 20 includes a semiconductor refrigerator 200, a water cooling head 201 and a PCB soft board 202. One side of the semiconductor refrigerator 200 is in contact with the product to be tested through the heat conducting plate 203, and the other side of the semiconductor refrigerator 200 is solidified on the surface of the water cooling head 201 through a thermally conductive adhesive. The heat conducting plate 203 is limitedly fitted on the semiconductor refrigerator 200, and the water cooling head 201 is limitedly fitted on the temperature control base component 21 and connected to the water pipe 77. One end of the PCB soft board 202 is connected to the temperature control base component 21. It can be seen that the patent application provides a cold source for the product to be tested through the semiconductor refrigerator 200. Since the other side of the semiconductor refrigerator 200 generates heat, the semiconductor refrigerator 200 dissipates heat through the water cooling head 201. The water cooling head 201 cooperates with the water cooler through the water pipe 77 to take away a large amount of heat generated by the other side of the semiconductor refrigerator 200, thereby improving the cooling efficiency of the semiconductor refrigerator 200. The material of the heat conduction plate 203 is indium sheet, which is relatively soft and has good thermal conductivity, thereby ensuring a close fit between the product carrier 4 and the semiconductor refrigerator 200.
[0023] like Figures 3 to 5As shown, in this embodiment, the temperature control base assembly 21 includes a temperature control base mounting seat 210, an XY axis adjustment table 211, and a fixed plate 212. The temperature control assembly 20 and the product carrier 4 are both limitedly engaged on the fixed plate 212. The fixed plate 212 is fixed on the XY axis adjustment table 211. The XY axis adjustment table 211 is slidably engaged on the temperature control base mounting seat 210. The temperature control base mounting seat 210 is fixedly engaged on the mounting table 10. It can be seen that the temperature control component 20 and the product carrier 4 are both limitedly fitted on the fixed plate 212, and the fixed plate 212 fixes and supports the temperature control component 20 and the product carrier 4. At the same time, the fixed plate 212 is fixed to the XY axis adjustment table 211, and the XY axis adjustment table 211 slides with the temperature control base mounting seat 210. The XY axis adjustment table 211 can drive the temperature control component 20 and the product carrier 4 to approach the detection module 3. Adjust the knob on the XY axis adjustment table 211 so that the product carrier 4 is in a good test position.

The slide rails 213 are slidably matched with the XY axis adjustment platform 211. The front stopper 214 and the rear stopper 215 are respectively arranged at the front and rear ends of the temperature control base mounting seat 210. The front stopper 214 and the rear stopper 215 are limitedly matched with the XY axis adjustment platform 211. It can be seen that the XY axis adjustment platform 211 is slidably matched with the temperature control base mounting seat 210 through the slide rails 213. During the sliding match, the temperature control base mounting seat 210 is also provided with the front stopper 214 and the rear stopper 215 to limit the XY axis adjustment platform 211, so that the product carrier 4 is in a good test position.
[0025] like Figure 4 As shown, in this embodiment, a positioning pin 99 is provided on the fixing plate 212, and the positioning pin 99 is limitedly matched with the product carrier 4. It can be seen that the positioning pin 99 plays a positioning and guiding role when the product carrier 4 is limitedly matched with the fixing plate 212.
[0026] In this embodiment, the working principle of the utility model is as follows:
[0027] like Figures 1 to 6As shown, the operator pulls the handle 15 to open the sealing seat 11, limits the product carrier 4 to fit on the temperature control base assembly 21 through the positioning pin 99, moves the temperature control base assembly 21 of the installed product carrier 4 to the working position, rotates and fine-tunes the XY axis adjustment table 211, fixes the detection module 3 on the installation table 10 and contacts with the temperature control base assembly 21, closes the sealing cover 11, opens the manual valve 15, starts to introduce dry air into the enclosed space, and monitors the reading of the humidity sensor 13 in real time. When the humidity inside the enclosed space reaches the test requirement, turns on the water cooler 12 and the temperature control assembly 20, controls the temperature of the relevant parts of the product carrier 4, waits for the temperature to reach the test requirement, and then starts the next related test, which is repeated in sequence.
