[0034] The present embodiment provides a thermal transfer system 1000, which includes a thermal transfer device 100 and an external extension structure 300, and the thermal transfer device 100 and the external extension structure 300 are detachably connected. The thermal transfer system 1000 includes a manual state and a semi-automatic state. In the manual state, the thermal transfer device 100 and the external extension structure 300 are separated, and the user can directly drive the thermal transfer device 100 to move to process the workpiece to be processed.

Moreover, when the thermal transfer system 1000 is in a semi-automatic state, the thermal transfer device 100 is driven to move by the external extension structure 300 to process the workpiece to be processed. The user does not need to manually drive the thermal transfer device 100 to move, which can reduce the workload of the user when processing the workpiece to be processed, and can also improve the safety of the thermal transfer system 1000 in processing the workpiece to be processed, which is conducive to improving the processing efficiency and processing safety of the thermal transfer system 1000 in processing the workpiece to be processed.

[0037] In some embodiments, the thermal transfer system 1000 may further include a workbench 500, which is used to carry the workpiece to be processed. The workbench 500 is rotatably connected to the external expansion structure 300, and the external expansion structure 300 can drive the thermal transfer device 100 to rotate relative to the workbench, so that the thermal transfer device 100 can process the workpiece to be processed placed on the workbench 500.

[0041] The present embodiment provides a thermal transfer device 100, which is used to process a workpiece to be processed. The thermal transfer device 100 includes a housing 10, a heating element 20, a connecting element 30 and a fixing element 40. The housing 10 includes a first side 10a and a second side 10b arranged opposite to each other, and a groove 11 is arranged on the first side 10a of the housing 10, and the groove 11 is recessed toward the second side 10b. The heating element 20 is arranged on the second side 10b, and the heating element 20 is used to generate heat to provide heat to the thermal transfer device 100 when the workpiece is to be processed. The connecting element 30 is placed in the groove 11, part of the connecting element 30 is accommodated in the groove 11, and the other part is exposed outside the groove 11 and is protruded relative to the first side 10a. The fixing element 40 penetrates the connecting element 30 accommodated in the groove 11 and is connected to the housing 10 (the bottom wall of the groove 11) so that a detachable connection is formed between the connecting element 30 and the housing 10. The connecting member 30 exposed outside the groove 11 and protruding relative to the first side 10a is used to form a detachable connection with the external extension structure 300 of the thermal transfer system 1000, so that the thermal transfer system 1000 can be switched between a manual state and a semi-automatic state.

[0042] The thermal transfer device 100 and the thermal transfer system 1000 provided in this embodiment can be detachably connected to the external extension structure 300 through the connecting piece 30 of the thermal transfer device 100, so as to facilitate the installation of the thermal transfer device 100 to the external extension structure 300 and also facilitate the removal of the thermal transfer device 100 from the external extension structure 300, which is beneficial to improve the flexibility of the thermal transfer system 1000 formed by the thermal transfer device 100 and the external extension structure 300, thereby improving the maintenance and replacement efficiency of the thermal transfer system 1000 formed by the thermal transfer device 100 and the external extension structure 300, and improving the efficiency of switching the thermal transfer device 100 between the manual state and the semi-automatic state. Moreover, when the thermal transfer device 100 is connected to the external extension structure 300, a groove 11 is provided on the shell 10, and at least a portion of the connecting member 30 is accommodated in the groove 11, so that the connection between the thermal transfer device 100 and the external extension structure 300 is more compact, and the assembly space between the thermal transfer device 100 and the external extension structure 300 can be reduced, which is beneficial to improving the application range of the thermal transfer device 100.

[0043] In a possible embodiment of the present application, the fixing member 40 passes through the connecting member 30 received in the groove 11 and is detachably connected to the housing 10 (the bottom wall of the groove 11), so that a detachable connection is formed between the connecting member 30 and the housing 10. Since the connecting member 30 and the external extension structure 300 are detachably connected, the connecting member 30 is also detachably mounted on the housing 10 through the fixing member 40, so as to facilitate the installation and removal between the thermal transfer device 100 and the external extension structure 300, thereby improving the efficiency of switching the thermal transfer device 100 between the manual state and the semi-automatic state.

[0044] It can be understood that in order to make the thermal transfer device 100 more operable in the manual state, the thermal transfer device 100 also includes a handle 50, which is arranged on the first side 10a of the shell 10. The user can hold the handle 50 of the thermal transfer device 100 to drive the thermal transfer device 100 to move on the surface of the workpiece to be processed, thereby allowing the thermal transfer device 100 to process the workpiece to be processed.

[0045] In a possible embodiment of the present application, in order to enable the thermal transfer device 100 to apply a uniform force to the workpiece to be processed by the user driving the handle 50 when the thermal transfer device 100 is in a manual state, the number of handles 50 can be set to two. The user drives the two handles 50 at the same time to drive the thermal transfer device 100 to move on the workpiece to be processed, so that the force on the workpiece to be processed is more uniform, which is beneficial to improving the processing effect of the thermal transfer device 100 on the workpiece to be processed, thereby ensuring the processing quality of the workpiece to be processed by the thermal transfer device 100.

[0046] See also Figure 2 and Figure 3 In a specific embodiment, a first surface is provided on the first side 10a of the shell 10, and the groove 11 is opened on the first surface of the first side 10a, and the groove 11 is located in the middle position of the first surface, that is, the groove 11 is provided in the middle position of the first side 10a.

[0047] In a possible embodiment of the present application, the geometric center of the opening of the groove 11 on the first surface of the first side 10a coincides with the geometric center of the first surface of the first side 10a, so that after the connecting member 30 is installed in the groove 11, the connecting member 30 is located at the geometric center of the first surface of the first side 10a.

[0048] The thermal transfer device 100 provided in the present application is designed by coinciding the geometric center of the opening of the groove 11 on the first side 10a with the geometric center of gravity of the first side 10a itself, and the connecting member 30 is fixed in the groove 11 by the fixing member 40. When the connecting member 30 is connected to the external extension structure 300, the external extension structure 300 drives the thermal transfer device 100 to move to realize the processing. In this process, the force on the workpiece to be processed is more uniform, and the thermal transfer effect is better, which is beneficial to ensure the processing quality of the thermal transfer device 100.

[0049] It can be understood that in some other embodiments, the geometric center of the first surface on the opening first side 10a of the groove 11 may deviate from the geometric center of the first side 10a. After the connecting member 30 is installed in the groove 11, the connecting member 30 deviates from the geometric center of the first surface of the first side 10a. The present application does not impose any restrictions on this.

Moreover, when the thermal transfer device 100 is switched from a semi-automatic state to a manual state, the extension portion 32 exposed from the groove 11 is convenient for taking the connecting member 30 out of the groove 11.

[0053] See also Figures 2 to 5 , Figure 5 It is a structural schematic diagram of a connecting piece provided in one embodiment of the present application.

[0063] More specifically, in this embodiment, the mating male groove 321 is a dovetail male groove, and the mating female groove 301 is a dovetail female groove.

[0064] The thermal transfer device 100 and the thermal transfer system 1000 provided in the present application form a detachable connection by cooperating between the male dovetail groove on the extension part 32 and the female dovetail groove on the external extension structure 300, so that the structure of the detachable connection between the thermal transfer device 100 and the external extension structure 300 is simple, thereby making the installation and disassembly between the thermal transfer device 100 and the external extension structure 300 convenient and quick, which is conducive to improving the switching of the thermal transfer system 1000 between the manual state and the semi-automatic state.

When the user needs to remove the thermal transfer device 100 from the external extension structure 300, the user can press the button 3015 to move the limiting column 3013 in a direction away from the limiting hole 3213 until the limiting column 3013 is disengaged from the limiting hole 3213, and then the thermal transfer device 100 can be removed from the external extension structure 300.

[0071] In one embodiment, the principle of the user operating the button 3015 to achieve the matching or disassembly of the limiting column 3013 and the limiting hole 3213 can be as follows. An elastic member 3016, a first wedge block 3017, and a second wedge block 3018 are connected between the button 3015 and the limiting column 3013, wherein the button 3015 is connected to one end of the elastic member 3016, the first wedge block 3017 is connected to the other end of the elastic member 3016, the inclined surface of the first wedge block 3017 is arranged to fit the inclined surface of the second wedge block 3018, and the second wedge block 3018 is connected to the limiting column 3013. When the user applies pressing force to the button 3015, the elastic member 3016 is compressed, and the pressing force applied by the user is transmitted to the first wedge block 3017 through the elastic member 3016. The first wedge block 3017 moves relative to the second wedge block 3018. Since the inclined surfaces of the first wedge block 3017 and the second wedge block 3018 fit together, the second wedge block 3018 moves in a direction away from the limiting hole 3213 under the push of the first wedge block 3017, thereby causing the limiting column 3013 to also move in a direction away from the limiting hole 3213, thereby causing the limiting column 3013 to disengage from the limiting hole 3213.

[0073] The thermal transfer device 100 provided in this embodiment is Figure 2 The heat transfer device 100 shown is substantially the same, except that, in the heat transfer device 100 provided in this embodiment, the size of the groove 11 along the direction from the first side 10a to the second side 10b gradually decreases, and the cross-sectional area of ​​the connecting portion 31 along the direction from the first side 10a to the second side 10b gradually decreases. In other words, the groove 11 provided in this embodiment is a trumpet-shaped expansion structure, and the connecting portion 31 provided in this embodiment is a truncated cone.

[0074] The thermal transfer device 100 provided in the present application gradually reduces the size of the groove 11 along the direction from the first side 10a to the second side 10b, so that the groove 11 forms a trumpet-shaped expansion structure, and the cross-sectional area of ​​the connecting portion 31 along the direction from the first side 10a to the second side 10b gradually becomes smaller, so that the connecting portion 31 is in the shape of a truncated cone. When the connecting portion 31 is installed in the groove 11, there is no need for deliberate alignment, which is beneficial to improving the installation efficiency of the connecting member 30 in the groove 11 of the shell 10.

[0076] The thermal transfer device 100 provided in this embodiment is Figure 2 The thermal transfer device 100 shown is substantially the same, except that, in the thermal transfer device 100 provided in this embodiment, a first mark 12 is provided on the first side 10a of the shell 10, a second mark 34 is provided on the connecting member 30, and the first mark 12 is aligned with the second mark 34.

[0077] The thermal transfer device 100 provided in the present application sets a first mark 12 on the first side 10a and sets a second mark 34 on the connector 30. When the connector 30 is placed in the groove 11, the user can align the first mark 12 and the second mark 34 to place the connector 30 in the groove 11 with an accurate posture to achieve an anti-foolproof function and facilitate the fixing member 40 to pass through the connector 30 and connect with the shell 10.
