[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] See also Figures 1 to 4 as well as Figure 6 , Figure 7 The trolley 10 provided in the embodiment of the present application is now described. The trolley 10 provided in the embodiment of the present application includes a body 102 and a first power connector 101. The body 102 is a box structure with an opening at one end. The heating fixture 20 can enter and exit the body 102 through the opening of the body 102. The body 102 is provided with a connection component 103 that can be electrically connected to the heating fixture 20. The direction in which the body 102 enters and exits the vacuum cabinet 30 is defined as a first direction, which is denoted as X. The first power connector 101 is disposed on the body 102 and is disposed in the first direction. The first power connector 101 is electrically connected to the connecting assembly 103; the vacuum cabinet 30 is provided with a second power connector 302 that can be connected to a power source, and the second power connector 302 is arranged in a first direction. When the vehicle body 102 enters and exits the vacuum cabinet 30 along the first direction, the second power connector is opposite to the first power connector 101 along the first direction. When the vehicle body 102 moves along the first direction to a preset position in the vacuum cabinet 30, the first power connector 101 is electrically connected to the second power connector 302 along the first direction.

[0032] The body 102 of the trolley 10 of the embodiment of the present application serves as a container that can accommodate multiple heating clamps 20. The heating clamps 20 enter the vacuum cabinet 30 through the support of the body 102. The trolley 10 also has a configuration for electrically connecting the heating clamps 20 to the vacuum cabinet 30, wherein the first power connector 101 and the connecting component 103 provided on the body 102 are electrically connected, and the connecting component 103 is electrically connected to the heating clamps 20 in the body 102. When the body 102 enters the vacuum cabinet 30 to a preset position, the first power connector 101 moves synchronously with the body 102 to be electrically connected to the second power connector 302 in the vacuum cabinet 30, and the second power connector 302 in the vacuum cabinet 30 is a configuration that can be connected to a power source. At this time, when the second power connector 302 is connected to the power source, the heating clamp 20 in the body 102 is also connected to the power source, so that the heating clamp 20 can perform a heating treatment process.

[0033] Among them, the electrical connection direction of the first power connector 101 and the second power connector 302 is the same as the direction in which the vehicle body 102 enters the vacuum cabinet 30. The first power connector 101 can be electrically connected to the second power connector 302 when the vehicle body 102 enters the vacuum cabinet 30 to a preset position. The preset position can be understood as the position corresponding to the vehicle body 102 when the vehicle body 102 completely enters the vacuum cabinet 30 and meets the normal operation requirements of the vacuum cabinet 30. The electrical connection of the first power connector 101 and the second power connector 302 uses this position as the docking mark, that is, when the vehicle body 102 moves to the preset position, the heating fixture 20 can be powered on, so that the power connection between the trolley 10 and the vacuum cabinet 30 does not require a separate process control. Of course, when the trolley 10 and the vacuum cabinet 30 need to be powered off, the trolley 10 only needs to be moved outside the vacuum cabinet 30 along the first direction. Therefore, the trolley 10 of the embodiment of the present application not only reduces the manufacturing cost of the electrical connection with the vacuum cabinet 30 , but also reduces the time cost of the heating treatment process of the heating fixture 20 .

[0034] It is understandable that the first power connector 101 is not limited to the position on the vehicle body 102 as long as it can be electrically connected to the second power connector 302 along the first direction, for example, it can be disposed on the upper side, lower side or other side of the vehicle body 102 .

[0035] It should be noted that the heating clamp 20 can be electrically connected to the connecting component 103 after entering the vehicle body 102, or before entering the vehicle body 102; and the electrical connection between the first electrical connector 101 and the second electrical connector 302 along the first direction can be a contact connection, or a plug-in connection similar to a socket and a plug.

[0036] See also Figure 2 and Figure 3Furthermore, the first power connector 101 in the above embodiment is provided with a first conductive portion 1011, and the first conductive portion 1011 is elastically and retractably arranged on the vehicle body 102 along the first direction, and the first conductive portion 1011 is electrically connected to the connecting component 103; when the vehicle body 102 moves along the first direction to a preset position in the vacuum cabinet 30, the first conductive portion 1011 and the second power connector 302 are abutted against each other along the first direction to be electrically connected.

[0037] The first conductive part 1011 of the first power connector 101 is a conductor, and the first conductive part 1011 is elastically extendable along the first direction. It can be understood that when the end of the first conductive part 1011 away from the vehicle body 102 is subjected to pressure along the first direction, it can be contracted toward the vehicle body 102, and when the pressure is removed, it is elastically restored to its original state. In which, the embodiment of the present application takes the electrical connection of the first conductive part 1011 and the second electrical connector 302 by abutting against each other along the first direction as an example, the contact method is more convenient for electrical connection, the first conductive part 1011 and the connecting component 103 are in an electrically connected state, when the first conductive part 1011 and the second electrical connector 302 are electrically connected along the first direction, that is, the heating clamp 20 and the second electrical connector 302 are electrically connected, wherein the elastic buffering effect can protect both the first conductive part 1011 and the second electrical connector 302, and effectively weaken the damage caused by the mutual impact when the first conductive part 1011 and the second electrical connector 302 are in contact along the first direction, and at the same time, the first conductive part 1011 is subjected to the elastic effect, which can help to keep the first conductive part 1011 and the second electrical connector 302 in contact and thus maintain the state of electrical connection.

[0038] It should be noted that the elastic extension setting of the first conductive part 1011 can be achieved by using a spring to elastically connect the first conductive part 1011 and the vehicle body 102, or by using other components with elastic requirements to make the first conductive part 1011 elastically and extendably set on the vehicle body 102 along the first direction.

[0039] See also Figure 3 and Figure 6, further, the area of ​​the abutting end of the first conductive part 1011 in the above embodiment is less than or equal to the area of ​​the corresponding abutting end of the second electrical connector 302. It can be understood that the area relationship between the contact ends of the first conductive part 1011 and the second electrical connector 302 is: the end surface area S1 of the second electrical connector 302 in contact with the first conductive part 1011 is greater than or equal to the end surface area S2 of the first conductive part 1011 in contact with the second electrical connector 302. When S1=S2, the first conductive part 1011 and the second electrical connector 302 need to have a higher docking accuracy so as to achieve electrical connection; and when S1>S2, the first conductive part 1011 has a larger contact area. In actual implementation, it can allow the vehicle body 102 to deviate from the first direction by a certain accuracy error, which is conducive to reducing the precision control cost in manufacturing and also convenient for reducing the difficulty of implementation. The embodiment of this application takes S1>S2 as an example.

[0040] The vehicle body 102 of the above embodiment is provided with an insulating mounting portion 104 corresponding to the first conductive portion 1011, and the first conductive portion 1011 is elastically and telescopically arranged on the mounting portion 104 along the first direction. It can be understood that the first conductive portion 1011 is connected to the vehicle body 102 through the insulating mounting portion 104, so that the first conductive portion 1011 is insulated and connected to the vehicle body 102, and the first conductive portion 1011 and the vehicle body 102 are prevented from generating a short circuit hazard. It should be noted that the first conductive portion 1011 is elastically and telescopically arranged relative to the vehicle body 102 along the first direction, and the mounting portion 104 and the vehicle body 102 can be relatively fixedly arranged, and the first conductive portion 1011 can be elastically and telescopically arranged on the mounting portion 104 along the first direction, or the first conductive portion 1011 can be fixedly arranged relative to the mounting portion 104, and the mounting portion 104 can be elastically and telescopically arranged on the vehicle body 102 along the first direction.

[0041] See also Figure 1 Further, the connecting component 103 of the above embodiment may include a connecting portion 1031 and a second conductive portion (not shown in the figure), the connecting portion 1031 connects the vehicle body 102 and the heating fixture 20, the connecting portion 1031 may move along with the movement of the vehicle body 102 along the first direction, and the second conductive portion (not shown in the figure) electrically connects the heating fixture 20 and the first electrical connector 101 along the connecting portion 1031.

[0042] In the embodiment of the present application, it can be understood that the connecting portion 1031 is a protective structure of the second conductive portion (not shown in the figure), the second conductive portion (not shown in the figure) can be a flexible wire, the connecting portion 1031 can be any protective shell structure that satisfies the setting of being retractable or foldable along the first direction, the second conductive portion (not shown in the figure) is covered by the connecting portion 1031 or attached to the connecting portion 1031 and arranged along the connecting portion 1031, the connecting portion 1031 connects the heating fixture 20 structure and the structure of the vehicle body 102, and the second conductive portion (not shown in the figure) electrically connects the heating fixture 20 and the first conductive portion 1011 arranged on the vehicle body 102. Of course, the length of the second conductive portion (not shown in the figure) is greater than or equal to the length of the connecting portion 1031, which can protect the second conductive portion (not shown in the figure) from being torn off. In the embodiment of the present application, the direction in which the heating fixture 20 is placed on the vehicle body 102 and the setting position of the connecting component 103 are not specifically described, and any setting that meets the above requirements is acceptable.

[0043] It is understandable that when the vehicle body 102 accommodates multiple heating fixtures 20, multiple groups of connecting components 103, first conductive parts 1011 and second electrical connectors 302 can be provided accordingly. The simple principle of increase and decrease is a conventional method for those skilled in the art and will not be elaborated.

[0044] Specifically, the second direction and the third direction are defined, the second direction is denoted as Y, the third direction is denoted as Z, the first direction, the second direction and the third direction are respectively perpendicular, the first direction and the second direction are respectively parallel to the horizontal plane, and the third direction is parallel to the vertical plane.

[0045] See also Figure 1 , Figure 4 and Figure 5The vehicle body 102 of the above embodiment is taken as an example of a rectangular structure, and the first direction is taken as the length direction of the vehicle body 102, the second direction is taken as the width direction of the vehicle body 102, and the third direction is taken as the height direction of the vehicle body 102. An opening is provided at one end of the vehicle body 102 in the first direction, and the first power connection member 101 is provided at the other end of the vehicle body 102 in the first direction. The heating fixture 20 can be stacked and placed in the vehicle body 102 along the third direction; at least one first support member 105 extending along the first direction is provided on the inner side of one side wall of the vehicle body 102 in the second direction, and at least one first support member 105 extending along the first direction is provided on the inner side of the other side wall of the vehicle body 102 in the second direction. At least one second support member 106 extending along the first direction is provided, and each first support member 105 is arranged opposite to a second support member 106 along the second direction; a rotatable first rolling component 201 is respectively provided at both ends of the heating clamp 20 in the second direction, one end of the heating clamp 20 in the second direction is rollingly matched with a first support member 105 along the first direction through the corresponding first rolling component 201, and the other end of the heating clamp 20 in the second direction is rollingly matched with a second support member 106 opposite to the first support member 105 along the second direction through the corresponding first rolling component 201.

[0046] In the embodiment of the present application, the heating clamp 20 is rollingly matched with the first support member 105 and the corresponding second support member 106 set on the inner wall of the vehicle body 102 in the width direction through the first rolling component 201, so that the heating clamp 20 can move in and out of the vehicle body 102 by rolling along the first direction with the help of the first rolling component 201. The rolling friction is small, which helps to easily control the heating clamp 20 to enter and exit the vehicle body 102. The first roller 2011 component is set on the heating clamp 20, which can replace the heating clamp 20 in direct contact with the vehicle body 102 or the first support member 105 and the second support member 106, thereby avoiding wear of the heating clamp 20 and helping to extend the service life.

[0047] The first support member 105 and the second support member 106 can be a strip structure that supports the heating clamp 20 along the third direction. When a plurality of first support members 105 and second support members 106 are respectively provided, a plurality of first support members 105 are arranged on the inner wall of one side of the vehicle body 102 at intervals along the third direction, and a plurality of second support members 106 are also arranged on the inner wall of the other side of the vehicle body 102 at corresponding intervals along the third direction. It can be understood that each first support member 105 and a corresponding second support member 106 along the second direction form a group, and each group of first support members 105 and second support members 106 is used to support a heating clamp 20. Of course, the interval between each group of first support members 105 and second support members 106 and the adjacent group of first support members 105 and second support members 106 along the third direction is greater than or equal to the height of a heating clamp 20.

[0048] The first power connector 101 is disposed on a side wall of the vehicle body 102 opposite to the opening along the first direction, that is, when the vehicle body 102 enters the vacuum cabinet 30, the side wall of the vehicle body 102 is close to the inner side of the vacuum cabinet 30. Of course, the second power connector 302 is disposed on the side opposite to the side wall in the vacuum cabinet 30, so that when the vehicle body 102 moves to a preset position in the vacuum cabinet 30, the first power connector 101 and the second power connector 302 can contact and be electrically connected along the first direction.

[0049] See also Figure 1 Further, the first support member 105 and the second support member 106 in the above embodiment may respectively include a support portion 1051 and a stop portion 1052, and the support portion 1051 and the stop portion 1052 are respectively extended along the first direction and arranged on the vehicle body 102; the first rolling assembly 201 includes a first roller 2011 and a second roller 2012, the first roller 2011 rolls along the first direction and fits with the support portion 1051, and the support portion 1051 can support the first roller 2011 along the third direction; the second roller 2012 rolls along the first direction and fits with the stop portion 1052, and the stop portion 1052 can stop the second roller 2012 along the second direction.

[0050] The first rollers 2011 arranged at both ends of the heating clamp 20 along the second direction respectively correspond to the support portions 1051 of the first support member 105 and the support portions 1051 of the second support member 106 and have relative effects along the third direction, i.e., the vertical direction. It can be understood that the support portion 1051 mainly supports the heating clamp 20 in the vertical direction, and the first roller 2011 serves as a transmission structure for the heating clamp 20 to move along the first direction; and the second rollers 2012 arranged at both ends of the heating clamp 20 along the second direction respectively correspond to the stop portions 1052 of the first support member 105 and the stop portions 1052 of the second support member 106 and have relative effects along the second direction. It can be understood that the stop portion 1052 mainly serves as a stop and anti-deviate function for the heating clamp 20 in the second direction, and the second roller 2012 serves as a guiding and anti-deviate structure for the heating clamp 20 to move along the first direction, thereby helping the heating clamp 20 to enter the vehicle body 102 conveniently and accurately. In the embodiment of the present application, a plurality of first rollers 2011 and second rollers 2012 are respectively arranged along the first direction, and are specifically arranged evenly at equal intervals for example, so as to provide a uniform effect for the heating clamp 20 .

[0051] It should be noted that the surface of the support portion 1051 used to support the first rolling can be horizontally arranged or inclined to the horizontal plane, as long as it can provide vertical support for the first roller 2011. Similarly, the surface of the stopper 1052 used to stop the second roller 2012 can be vertically arranged or inclined to the vertical plane, as long as it can provide a stopping effect along the second direction for the second roller 2012. In the embodiment of the present application, the surface of the support portion 1051 used to support the first rolling is horizontally arranged as an example, and the corresponding axial direction of the first roller 2011 is arranged along the second direction as an example; and the surface of the stopper 1052 used to stop the second roller 2012 is vertically arranged as an example, and the corresponding axial direction of the second roller 2012 is arranged along the third direction as an example. Among them, the support portion 1051 and the stopper 1052 can also be provided with a wear-resistant layer, such as rubber or other materials, to reduce the residue and dust generated by wear.

[0052] See also Figure 1 , Figure 6 and Figure 7 Further, similar to the cooperation between the heating fixture 20 and the vehicle body 102, a rotatable second rolling assembly 202 is provided at the bottom of the vehicle body 102 of the above embodiment, and a guide rail 301 extending along the first direction is provided in the vacuum cabinet 30, and the second rolling assembly 202 includes a third roller 2021 and a fourth roller 2022, and the third roller 2021 and the fourth roller 2022 are respectively rollingly matched with the guide rail 301 along the first direction, and the guide rail 301 can support the third roller 2021 along the third direction, and the guide rail 301 can stop the fourth roller 2022 along the second direction.
