[0036] In the prior art, the workpiece 001 is directly immersed in the cleaning liquid 002, the heater heats the cleaning liquid 002, accelerates the reaction speed of the cleaning liquid 002 and the dirt attached to the surface of the workpiece 001, and improves the cleaning efficiency. Since the workpiece 001 is directly immersed in the cleaning liquid 002, the amount of cleaning liquid 002 is large, the energy required to heat the cleaning liquid 002 is large, and the energy consumption is high. Moreover, the subsequent cleaning of the cleaning liquid 002 on the surface of the workpiece 001 is labor-intensive and difficult.

[0037] Therefore, the designer provides a non-contact cleaning liquid heating device, which can reduce the amount of cleaning liquid 002, reduce energy consumption and cost; at the same time, it is beneficial to the treatment of the cleaning liquid 002 on the surface of the workpiece 001 after cleaning.

Since only the cleaning liquid 002 is on the surface of the workpiece 001, it is not necessary to immerse the workpiece 001 in a cleaning tank, so that the amount of cleaning liquid 002 can be reduced, thereby reducing energy consumption and saving cost. At the same time, in the process of cleaning the workpiece 001, the rotating table 200 drives the workpiece 001 to rotate, which can improve the heating uniformity of the cleaning liquid 002, thereby improving the cleaning effect of the workpiece 001.

The surrounding plate 111 and the cover plate 112 can be made of metal plates, which have high structural strength and long service life. The surrounding plate 111 can be provided with an open structure at both ends, and the cross-sectional profile of the surrounding plate 111 can be circular or rectangular.

In addition, the number of compression strips 113 can be multiple, and multiple compression strips 113 can be arranged in a cross shape to form a mesh structure, thereby improving the structural strength. When the compression strip 113 is installed on the cover plate 112, the compression strip 113 and the annular flange 1111 have a spacing therebetween, thereby forming a space for installing the insulating plate 130 and the heating plate 120.

[0046] Further, the cover plate 112 is provided with an assembly hole and a communication hole 1121. The assembly hole is located at the middle position of the cover plate 112, and the number of communication holes 1121 can be multiple. The multiple communication holes 1121 can be arranged in a ring shape around the assembly hole, and the communication holes 1121 communicate with the area surrounded by the surrounding plate 111. The cooling cover 300 is installed on the top outer side of the cover plate 112, and the cooling cover 300 covers the assembly hole and the multiple communication holes 1121 at the same time. The cooling cover 300 and the cover plate 112 cooperate to form a top cooling cavity which communicates with the communication holes 1121. The cooling cover 300 is provided with an inlet 302, and the inlet 302 can introduce cooling gas into the top cooling cavity.

[0047] It should be understood that, in order to improve the sealing performance, a sealing ring 400 can be arranged between the cooling cover 300 and the cover plate 112.

It should be understood that the number of the heating plate 120 can be one, the heating plate 120 is attached to the heat insulation plate 130 located at the bottom of the two heat insulation plates 130, and the heating plate 120 is in contact with the annular folded edge 1111. In this way, the heating plate 120 is clamped by the heat insulation plate 130 and the annular folded edge 1111, and the heat insulation plate 130 is limited by the compression strip 113. In this way, the heat insulation plate 130 and the heating plate 120 are positioned in the area surrounded by the enclosure plate 111 through the cooperation of the compression strip 113 and the annular folded edge 1111.

[0049] Obviously, in other embodiments, the number of the heat insulation plates 130 is not limited to two, but can be one or other numbers, and correspondingly, the number of the heating plate 120 can also be multiple.

[0050] In addition, in order to improve the sealing performance, a sealing ring 400 can be arranged between the enclosure plate 111, the heat insulation plate 130 and the heating plate 120.

[0051] Please refer to Figures 3-6 Optionally, the temperature measuring instrument 140 includes a mounting seat 141, an infrared temperature measuring body 142, a corrosion-resistant light-transmitting sheet 143 and a guide cylinder 144. The mounting seat 141 is arranged in the assembly hole and can be fixedly connected with the cover plate 112 through bolts or the like. The mounting seat 141 cooperates with the cover plate 112 to form a middle cooling cavity, a top cooling cavity is in communication with the middle cooling cavity through a communication hole 1121, and the middle cooling cavity is in communication with the heat dissipation cavity 114. In this way, the cooling gas introduced from the inlet 302 enters the second cooling cavity 301 after passing through the first cooling cavity 1411, and then enters the heat dissipation cavity 114, and is discharged from the top of the cover plate 112 and the gap between the cover plate 112 and the enclosure plate 111, etc. to achieve the purpose of cooling the mounting seat 141 and the corrosion-resistant light-transmitting sheet 143 and other structural components. It should be understood that the middle cooling cavity can be referred to as the first cooling cavity 1411, and the top cooling cavity can be referred to as the second cooling cavity 301.

[0052] Meanwhile, the infrared temperature measuring body 142 is installed above the mounting seat 141 and extends out of the top of the cover plate 112, and the infrared temperature measuring instrument 140 body penetrates the cooling cover 300, which can be screwed with the infrared temperature measuring instrument 140 body to improve the stability of the structure. The guide cylinder 144 can be installed below the mounting seat 141 in a screwing manner, and the guide cylinder 144 is coaxially arranged with the assembly hole, and the guide cylinder 144 penetrates the heating plate 120 and the heat insulation plate 130 at the same time. The corrosion-resistant light-transmitting sheet 143 is installed on the mounting seat 141 and located between the infrared temperature measuring body 142 and the guide cylinder 144. In this way, the infrared temperature measuring instrument 140 body can monitor the temperature of the workpiece 001 from the guide cylinder 144 through the corrosion-resistant light-transmitting sheet 143.

[0053] Please refer to Figures 5-6 Moreover, the mounting seat 141 is provided with a fluid channel 1412 which is independent of the second cooling cavity 301, and the fluid channel 1412 communicates with the top end of the guide cylinder 144 and is located between the corrosion-resistant light-transmitting sheet 143 and the guide cylinder 144. The fluid channel 1412 is used to introduce gas to carry away the steam generated by the heated cleaning liquid 002 entering the guide cylinder 144 from below, and to cool the mounting seat 141 and the corrosion-resistant light-transmitting sheet 143. That is to say, due to the design of the corrosion-resistant light-transmitting sheet 143, during the cleaning process of the workpiece 001, the steam generated after the cleaning liquid 002 is heated will enter the guide cylinder 144 and be blocked by the corrosion-resistant light-transmitting sheet 143, and the steam is not easy to directly contact with the infrared temperature measuring instrument 140 body and damage the infrared temperature measuring instrument 140 body. If the steam directly contacts with the corrosion-resistant light-transmitting sheet 143, water droplets are easy to form on the corrosion-resistant light-transmitting sheet 143, which affects the accuracy of the temperature measurement result of the infrared temperature measuring instrument 140 body. Therefore, introducing gas with a certain pressure through the fluid channel 1412 can carry away the steam and avoid the steam from adhering to the corrosion-resistant light-transmitting sheet 143.

[0054] In order to facilitate the introduction of gas, a gas inlet 1413 and a gas outlet 1414 can be arranged on the mounting seat 141, and the gas introduced through the gas inlet 1413 flows in the fluid channel 1412 and is discharged from the gas outlet 1414.

[0055] In this embodiment, the rotating table 200 can be driven by a motor or other structure to adjust the speed and adapt to different cleaning scenarios.

[0056] In this embodiment, the structure design of the non-contact cleaning liquid heating device can reduce the amount of cleaning liquid 002, reduce resource consumption, and save cleaning cost; at the same time, it is beneficial to clean the residual cleaning liquid 002 on the workpiece 001 after cleaning. During the cleaning process, the workpiece 001 and the cleaning liquid 002 rotate together relative to the heating plate 120, so that the workpiece 001 and the cleaning liquid 002 are uniformly heated, and the workpiece 001 has good cleaning effect.

[0057] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
