Description

Technical Field

[0001] This application relates to the technical field of mechanical equipment, and particularly relates to a heavy-load platform alignment mechanism. Background Art

[0002] Semiconductor equipment is a highly integrated complex system, so semiconductor equipment is generally a heavy-load equipment with a large volume and large weight. The machine platform of some heavy-load equipment needs to be installed on the bearing surface of the heavy-load platform. Among them, the heavy-load platform can be the bottom plate of the housing of the corresponding heavy-load equipment or the bearing platform of another heavy-load equipment.

[0003] Currently, due to the relatively narrow space for installing the machine platform on the heavy-load platform and the large weight of the machine platform, the precise positioning and installation of heavy-load equipment has always been a technical problem in the semiconductor industry. Existing solutions all use manpower for alignment, and it is difficult to accurately adjust the position of heavy-load equipment during the alignment process, so precise positioning can basically not be achieved. Utility Model Content

[0004] The embodiments of this application provide a heavy-load platform alignment mechanism, which can achieve relatively high movement accuracy, is easier to adjust the position of the piece to be positioned, and enables the piece to be positioned to reach a relatively high positioning accuracy.

[0005] The embodiments of this application provide a heavy-load platform alignment mechanism, which includes a plurality of abutting components. Each abutting component includes a support and at least one fine-tuning abutting element arranged on the support. Each fine-tuning abutting element is used to apply an abutting force to the piece to be positioned, so that each abutting component can provide an abutting force in at least one direction; the plurality of abutting components are spaced apart along the circumferential side of the piece to be positioned, providing a plurality of abutting forces directed towards the piece to be positioned to push the piece to be positioned towards the target position.

[0006] In some embodiments, the support includes a base and a side wall. The base and the side wall intersect and are connected to form an accommodating space. The base is used to be fixed on the heavy-load platform, and the fine-tuning abutting element is installed on the side wall and extends into the accommodating space.

[0007] In some embodiments, the fine-tuning abutting element includes a hydraulic cylinder. The hydraulic cylinder includes a cylinder body installed on the side wall and a piston rod slidably connected to the cylinder body. The cylinder body drives the piston rod to move in a hydraulic driving manner to apply an abutting force to the piece to be positioned by the piston rod; and / or, the side wall has a first wall surface, and the first wall surface is perpendicular to the direction of the abutting force provided by the corresponding fine-tuning abutting element, and the end surface of the corresponding fine-tuning abutting element facing away from the piece to be positioned tightly abuts against the first wall surface.

The recess direction of the accommodating groove is parallel to the direction of the abutting force provided by the corresponding fine-tuning abutting element, and the end of the fine-tuning abutting element away from the piece to be positioned is embedded in the accommodating groove.

[0009] In some embodiments, one end of the accommodating groove in the length direction penetrates through the end face of the side wall to form a notch, so that the fine-tuning abutting element can disengage from the side wall along the notch under the action of an external force.

[0010] In some embodiments, the plurality of abutting members are divided into a first group and a second group. The first group and the second group each include more than two abutting members. In the use state of the alignment mechanism, the abutting members in the first group are used to provide an abutting force along a first direction to the workpiece to be positioned; the abutting members in the second group are used to provide an abutting force along a second direction to the workpiece to be positioned. The first direction, the second direction and the height direction of the workpiece to be positioned intersect.

[0011] In some embodiments, the plurality of abutting members are divided into a first group, a second group and a third group. The first group, the second group and the third group each include at least one abutting member. The abutting members in the third group have at least two fine-tuning abutting elements and can provide abutting forces in two directions. In the use state of the alignment mechanism, the abutting members in the third group are arranged at the corners of the workpiece to be positioned. The corresponding part of the fine-tuning abutting elements of each abutting member in the third group is used to provide an abutting force along the first direction towards the first side face; the corresponding other part of the fine-tuning abutting elements of each abutting member in the third group is used to provide an abutting force along the second direction towards the second side face; the abutting members in the first group are used to provide an abutting force along the first direction towards the first side face; the abutting members in the second group are used to provide an abutting force along the second direction towards the second side face. The corner is formed by the intersecting first side face and second side face. The first direction, the second direction and the height direction of the workpiece to be positioned intersect.

[0012] In some embodiments, the heavy-duty platform alignment mechanism further includes a heavy-duty platform having a bearing surface for bearing the workpiece to be positioned. The bearing surface is engraved with a coarse adjustment reference line and a fine adjustment reference line. The coarse adjustment reference lines enclose a coarse adjustment area, and the fine adjustment reference lines enclose a fine adjustment area. The projection area of the target position along the height direction of the workpiece to be positioned on the bearing surface coincides with the fine adjustment area. The area of the coarse adjustment area is larger than the area of the fine adjustment area. Along the first direction, the coarse adjustment area is closer to the first group than the fine adjustment area. Along the second direction, the coarse adjustment area is closer to the second group than the fine adjustment area; and / or, the first direction is perpendicular to the second direction.

[0013] In some embodiments, it further includes a plurality of wheeled components, and the wheeled components include: rollers; a wheel frame including a first frame body and a second frame body whose relative positions are adjustable along a third direction. The first frame body is used for detachably mounting to the workpiece to be positioned, and the rollers are rotatably connected to the second frame body. The third direction is parallel to the height direction of the workpiece to be positioned.

[0014] In some embodiments, the second frame is provided with a screw rod extending along a third direction, the first frame is provided with a lapping hole adapted to the screw rod, at least a part of the screw rod extends into the lapping hole from the side of the lapping hole facing the roller, and a first nut threadedly connected to the screw rod is arranged on the side of the lapping hole facing the roller; the lapping hole is in the form of a through hole, the screw rod extends out from the side of the lapping hole facing away from the roller, and a second nut threadedly connected to the screw rod is arranged on the side of the lapping hole facing away from the roller.

[0015] The heavy-duty platform alignment mechanism of the embodiments of the present application includes a plurality of abutting components. Each abutting component includes a support and at least one fine-tuning abutting element arranged on the support. Each fine-tuning abutting element is used to apply an abutting force to the piece to be positioned, so that each abutting component can provide an abutting force in at least one direction; the plurality of abutting components are spaced apart along the circumferential side of the piece to be positioned, providing a plurality of abutting forces directed towards the piece to be positioned to push the piece to be positioned towards the target position. It can be understood that the piece to be positioned can be the machine table of a heavy-duty device, the support is used for fixed installation on the heavy-duty platform, and the target position is located on the bearing surface of the heavy-duty platform. The staff can manually move the piece to be positioned to an area close to the target position, and then apply an abutting force to the piece to be positioned through the fine-tuning abutting element of the abutting component, so that the piece to be positioned can move relative to the heavy-duty platform. Since the plurality of abutting components are spaced apart along the circumferential side of the piece to be positioned, abutting forces can be provided to the piece to be positioned from multiple directions. The cooperation of the plurality of abutting components can enable the piece to be positioned to gradually move to the target position, thereby completing the alignment of the heavy-duty platform and the piece to be positioned. Since the abutting component is a mechanical device, compared with directly adjusting a large-volume and heavy-piece to be positioned to the target position manually, a higher movement accuracy can be achieved, it is easier to adjust the position of the piece to be positioned, and the piece to be positioned can reach a relatively high positioning accuracy; since the abutting component only includes a support and a fine-tuning abutting element, the volume of the abutting component is relatively small and can be directly installed on the heavy-duty platform. In a narrow space, it is not easy for the staff to apply a force in a specific direction to the piece to be positioned. The advantage of adjusting the position of the piece to be positioned through a plurality of abutting components to achieve a high positioning accuracy is more obvious.

[0032] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0033] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.

[0034] Semiconductor devices are highly integrated complex systems, so semiconductor devices are generally heavy-duty devices with large volume and large weight. The machines of some heavy-duty devices need to be installed on the bearing surface of the heavy-duty platform. Among them, the heavy-duty platform can be the bottom plate of the housing of the corresponding heavy-duty device or the bearing table of another heavy-duty device.

[0035] It has been found through research that due to the relatively narrow space for installing the machine on the heavy-duty platform and the large weight of the machine, the precise positioning and installation of heavy-duty devices have always been a technical problem in the semiconductor industry. Existing solutions all use manual alignment, and it is difficult to accurately adjust the position of heavy-duty devices during the alignment process, so precise positioning cannot be basically achieved.

[0036] To solve the problems of the prior art, the embodiments of the present application provide a heavy-duty platform alignment mechanism. The following will be introduced in detail with reference to the drawings.

[0037] Figure 1 Schematic diagram of the cooperation structure between the heavy-duty platform alignment mechanism provided by some embodiments of the present application and the piece to be positioned; Figure 2 Schematic diagram of the structure of the heavy-duty platform provided by some embodiments of the present application; Figure 3 Schematic diagram of the structure of the bearing member provided by some embodiments of the present application; Figure 4 Schematic diagram of the structure of the heavy-duty platform alignment mechanism provided by some embodiments of the present application; Figure 5 Schematic diagram of the structure of the heavy-duty platform alignment mechanism provided by other embodiments of the present application.

[0038] Please refer to Figures 1 to 5, embodiments of the present application provide an alignment mechanism for a heavy-duty platform, including a plurality of abutting members 1. Each abutting member 1 includes a support 11 and at least one fine-tuning abutting element 12 disposed on the support 11. Each fine-tuning abutting element 12 is configured to apply an abutting force to the piece to be positioned 2, so that each abutting member 1 can provide an abutting force in at least one direction; the plurality of abutting members 1 are spaced apart along the circumferential side of the piece to be positioned 2, providing a plurality of abutting forces directed towards the piece to be positioned 2, so as to push the piece to be positioned 2 towards the target position.

[0039] It can be understood that the piece to be positioned 2 can be the machine table of a heavy-duty device. The support 11 is used for fixed installation to the heavy-duty platform 3, and the target position is located on the bearing surface 301 of the heavy-duty platform 3; along the circumferential side of the piece to be positioned 2 means along the direction of the height direction surrounding the piece to be positioned 2. Among them, when the piece to be positioned 2 is placed on the bearing surface 301, the height direction of the piece to be positioned 2 is perpendicular to the bearing surface 301. Specifically, as Figure 2 shown, in this embodiment, the heavy-duty platform and the piece to be positioned 2 belong to the same heavy-duty device. The heavy-duty platform is the bottom plate of the housing of the corresponding heavy-duty device, and side plates 4 detachably connected to the bottom plate are further provided on the circumferential side of the bottom plate. In some other embodiments, the heavy-duty platform and the piece to be positioned 2 can also belong to two heavy-duty devices respectively, and the heavy-duty platform is the bearing table of the corresponding heavy-duty device.

[0040] The staff can manually move the piece to be positioned 2 to an area close to the target position, and then apply an abutting force to the piece to be positioned 2 through the fine-tuning abutting element 12 of the abutting member 1, so that the piece to be positioned 2 can move relative to the heavy-duty platform. Since the plurality of abutting members 1 are spaced apart along the circumferential side of the piece to be positioned 2, abutting forces can be provided to the piece to be positioned 2 from multiple directions. The cooperation of the plurality of abutting members 1 can enable the piece to be positioned 2 to gradually move to the target position, and thus the alignment between the heavy-duty platform and the piece to be positioned 2 can be completed.

[0041] Since the abutting member 1 is a mechanical device, compared with directly adjusting a large-volume and heavy-weight piece to be positioned 2 to the target position manually, it can achieve a relatively high movement accuracy, and it is easier to adjust the position of the piece to be positioned 2 and make the piece to be positioned 2 reach a relatively high positioning accuracy; since the abutting member 1 only includes the support 11 and the fine-tuning abutting element 12, the volume of the abutting member 1 is relatively small and can be directly installed on the heavy-duty platform. In a narrow space, it is not easy for the staff to apply a force in a specific direction to the piece to be positioned 2. The advantage of adjusting the position of the piece to be positioned 2 through the plurality of abutting members 1 to achieve a relatively high positioning accuracy is more obvious; when a certain position on the circumferential side of the piece to be positioned 2 is an arc surface or an uneven special-shaped surface, an abutting member 1 with a plurality of fine-tuning abutting elements 12 can be selected, and the resultant force of the abutting forces respectively applied by the plurality of fine-tuning abutting elements 12 to the piece to be positioned 2 is directed towards a preset direction, so that the piece to be positioned 2 can reach the target position more easily.

[0042] As Figure 3 shown, in some embodiments, the support 11 includes a base 111 and a side wall 112. The base 111 and the side wall 112 intersect and are connected to form a receiving space. The base 111 is used for fixedly mounting to a heavy-duty platform. The fine adjustment abutting element 12 is mounted on the side wall 112 and extends into the receiving space. That is, the fine adjustment abutting element 12 is mounted on one side of the side wall 112 close to the base 111, making the support 11 and the fine adjustment abutting element 12 more compact. Furthermore, the overall volume of the bearing component 1 can be reduced, enabling the bearing component 1 to be more flexibly mounted to the heavy-duty platform. It can be understood that the mounting manner between the base 111 and the heavy-duty platform can be detachable mounting or non-detachable mounting. Specifically, in this embodiment, the base 111 is detachably mounted to the heavy-duty platform through corresponding bolts.

[0043] As Figure 3 , in some embodiments, the fine adjustment abutting element 12 includes a hydraulic cylinder. The hydraulic cylinder includes a cylinder body mounted on the side wall 112 and a piston rod slidably connected to the cylinder body. The cylinder body drives the piston rod to move in a hydraulic driving manner to apply an abutting force to the to-be-positioned member 2 by the piston rod. Hydraulic driving can generate a large driving force, and the feeding accuracy of the piston rod of the hydraulic cylinder can reach an accuracy of sub-millimeter or even dozens of micrometers, enabling the piston rod to have a high movement accuracy. It can be understood that the hydraulic cylinder can be an electric control hydraulic cylinder or a manual hydraulic cylinder, which is not limited herein.

[0044] As Figure 3 , in some embodiments, the side wall 112 has a first wall surface. The first wall surface is perpendicular to the direction of the abutting force provided by the corresponding fine adjustment abutting element 12. The end surface of the corresponding fine adjustment abutting element 12 facing away from the to-be-positioned member 2 abuts tightly against the first wall surface. During the process of the fine adjustment abutting element 12 pushing the to-be-positioned member 2, the reaction force applied by the to-be-positioned member 2 to the fine adjustment abutting element 12 and transmitted to the first wall surface is perpendicular to the first wall surface, which can reduce the risk of accidental slipping of the fine adjustment abutting element 12 along the first wall surface, and further improve the overall structural stability of the bearing component 1.

[0045] In some embodiments, the base 111 is in the shape of a flat plate, that is, the base 111 has a second wall surface for tightly abutting against the bearing surface 301, so that a surface contact can be formed between the base 111 and the bearing surface 301 of the heavy-duty platform, and the stability of the base 111 after being installed on the heavy-duty platform can be improved. The side wall 112 is in the shape of a flat plate or an arc-shaped plate, and the corresponding bolt can pass through the side wall 112 and be threadedly connected to the fine-tuning abutting element 12, which is convenient for the installation of the fine-tuning abutting element 12. The side wall 112 is perpendicular to the base 111, so that during the process of the fine-tuning abutting element 12 pushing the to-be-positioned part 2, most of the reaction forces received by the fine-tuning abutting element 12 can be directly transmitted to the side wall 112, and the strength requirement for the connecting piece between the fine-tuning abutting element 12 and the side wall 112 can be reduced.

[0046] As Figure 3 shown, in some embodiments, the side wall 112 is provided with a receiving groove, the recessed direction of the receiving groove is parallel to the direction of the abutting force provided by the corresponding fine-tuning abutting element 12, the end of the fine-tuning abutting element 12 away from the to-be-positioned part 2 is embedded in the receiving groove, and the groove walls on the periphery of the receiving groove can support the fine-tuning abutting element 12 to a certain extent, further improving the stability of the fine-tuning abutting element 12 installed on the side wall 112. It can be understood that the first wall surface is located at the bottom of the receiving groove.

[0047] As Figure 3 shown, in some embodiments, one end of the receiving groove in the length direction penetrates through the end surface of the side wall 112 to form a notch 1121, so that the fine-tuning abutting element 12 can be disengaged from the side wall 112 along the notch 1121 under the action of an external force. Among them, the length direction of the receiving groove is perpendicular to the recessed direction of the receiving groove. After the positioning member 1 completes the positioning work of the to-be-positioned part 2, the fine-tuning abutting element 12 can be first adjusted to the contracted state, after disassembling the connecting pieces such as bolts between the fine-tuning abutting element 12 and the side wall 112, the fine-tuning abutting element 12 is detached along the notch 1121, and then the support 11 is disassembled, which can improve the convenience and efficiency of disassembling the positioning member 1.

[0048] As Figure 4As shown, in some embodiments, a plurality of abutting members 1 are divided into a first group 1a and a second group 1b. The first group 1a and the second group 1b each include more than two abutting members 1. In the use state of the alignment mechanism, the abutting members 1 in the first group 1a are used to provide a holding force along the first direction X to the workpiece to be positioned 2, so that the workpiece to be positioned 2 can move along the first direction X towards the target position; the abutting members 1 in the second group 1b are used to provide a holding force along the second direction Y to the workpiece to be positioned 2, so that the workpiece to be positioned 2 can move along the second direction Y towards the target position. The first direction X, the second direction Y and the height direction of the workpiece to be positioned 2 intersect. The adjustment steps of the heavy-duty platform alignment mechanism can be as follows: Coarse adjustment of the position of the workpiece to be positioned 2. Move the workpiece to be positioned 2 manually above the bearing surface 301, so that the workpiece to be positioned 2 is located in a region closer to the first group 1a along the first direction X and closer to the second group 1b along the second direction Y relative to the target position; Fine adjustment of the position of the workpiece to be positioned 2. A plurality of abutting members 1 in the first group 1a control the corresponding fine-adjustment holding elements 12 to push the workpiece to be positioned 2 along the first direction X towards the target position, so that the workpiece to be positioned 2 gradually moves towards the target position in the first direction X; A plurality of abutting members 1 in the second group 1b control the corresponding fine-adjustment holding elements 12 to push the workpiece to be positioned 2 along the second direction Y towards the target position, so that the workpiece to be positioned 2 gradually moves towards the target position in the second direction Y. The first group 1a and the second group 1b cooperate to enable the workpiece to be positioned 2 to gradually move to the target position.

[0049] As Figure 5As shown, a plurality of abutting members 1 are divided into a first group 1a, a second group 1b, and a third group 1c. The first group 1a, the second group 1b, and the third group 1c each include at least one abutting member 1. The abutting members 1 in the third group 1c have at least two fine-tuning abutting elements 12 capable of providing abutting forces in two directions. In the use state of the alignment mechanism, the abutting members 1 in the third group 1c are arranged at the corners of the workpiece 2 to be positioned. The corresponding part of each abutting member 1 in the third group 1c of the fine-tuning abutting elements 12 is used to provide an abutting force toward the first side surface along the first direction X, and the corresponding other part of each abutting member 1 in the third group 1c of the fine-tuning abutting elements 12 is used to provide an abutting force toward the second side surface along the second direction Y; the abutting members 1 in the first group 1a are used to provide an abutting force toward the first side surface along the first direction X; the abutting members 1 in the second group 1b are used to provide an abutting force toward the second side surface along the second direction Y. The corner is formed by the intersecting first side surface and the second side surface. The first direction X, the second direction Y, and the height direction of the workpiece 2 to be positioned are intersectingly arranged. It can be understood that for the workpiece 2 to be positioned with a cylindrical surface structure on the periphery, since the curvature at each position along the periphery of the workpiece 2 is not zero, any position on the periphery of the workpiece 2 can be regarded as a corner, and the two sides of the corner can be regarded as the first side surface and the second side surface respectively. Under the combined action of the abutting force provided by some of the fine-tuning abutting elements 12 in the third group 1c toward the first side surface along the first direction X and the abutting force provided by the abutting members 1 in the first group 1a toward the first side surface along the first direction X, the workpiece 2 to be positioned can move toward the target position along the first direction X; under the combined action of the abutting force provided by the other part of the fine-tuning abutting elements 12 in the third group 1c toward the second side surface along the second direction Y and the abutting force provided by the abutting members 1 in the second group 1b toward the second side surface along the second direction Y, the workpiece 2 to be positioned can move toward the target position along the second direction Y. This solution can complete the positioning work of the workpiece 2 to be positioned through three abutting members 1, and the overall structure is simpler.

[0050] Figure 6 The structural schematic diagram of the heavy-duty platform alignment mechanism provided by some other embodiments of the present application.

[0051] As Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown in Figure 6As shown, the bearing surface 301 is engraved with a coarse adjustment reference line 3011 and a fine adjustment reference line 3012. The coarse adjustment reference line 3011 encloses a coarse adjustment area, and the fine adjustment reference line 3012 encloses a fine adjustment area. The projection area of the target position along the height direction of the to-be-positioned part 2 on the bearing coincides with the fine adjustment area. The area of the coarse adjustment area is larger than that of the fine adjustment area. Along the first direction X, the coarse adjustment area is closer to the first group 1a than the fine adjustment area, and along the second direction Y, the coarse adjustment area is closer to the second group 1b than the fine adjustment area. During the process of adjusting the position of the to-be-positioned part 2, the staff can quickly know whether the to-be-positioned part 2 reaches the expected position by comparing whether the current position of the to-be-positioned part 2 is within the coarse adjustment reference line 3011 or by comparing whether the current position of the to-be-positioned part 2 is within the fine adjustment reference line 3012, without the staff repeatedly measuring whether the position of the to-be-positioned part 2 reaches the expected position, which can improve the overall efficiency of adjusting the position of the to-be-positioned part 2. It can be understood that the expected position during the coarse adjustment of the position of the to-be-positioned part 2 refers to the position area within the coarse adjustment reference line 3011; the expected position during the fine adjustment of the position of the to-be-positioned part 2 refers to the position area within the fine adjustment reference line 3012.

[0052] As Figure 4 , Figure 5 and Figure 6 shown, in some embodiments, the first direction X is perpendicular to the second direction Y. During the process of pushing the to-be-positioned part 2 along the first direction X, there will be no displacement component of the to-be-positioned part 2 along the second direction Y; similarly, during the process of pushing the to-be-positioned part 2 along the second direction Y, there will be no displacement component of the to-be-positioned part 2 along the first direction X. Therefore, the adjustment efficiency of the fine adjustment of the position of the to-be-positioned part 2 can be improved.

[0053] Figure 7 FIG. is a schematic diagram of the cooperation structure between the wheeled component 5 and the to-be-positioned part 2 provided by some embodiments of the present application; Figure 8 FIG. is a schematic diagram of the structure of the wheeled component 5 provided by some embodiments of the present application.

[0054] As Figure 7 and Figure 8As shown, in some embodiments, the heavy-load platform alignment mechanism further includes a plurality of wheeled components 5. The wheeled component 5 includes a roller 51 and a wheel frame. The roller 51 is used to roll along the bearing surface 301. The wheel frame includes a first frame body 53 and a second frame body 52 whose relative positions are adjustable along the third direction Z. The first frame body 53 is used for detachably mounting to the piece to be positioned 2. The roller 51 is rotatably connected to the second frame body 52. The third direction Z is parallel to the height direction of the piece to be positioned 2. During the coarse adjustment of the position of the piece to be positioned 2, the frictional resistance between the piece to be positioned 2 and the bearing surface 301 can be reduced through the roller 51, facilitating the manual pushing of the piece to be positioned 2. Before the fine adjustment of the position of the piece to be positioned 2, the wheeled component 5 can be disassembled first to avoid the movement of the machine platform being out of control due to the inertia of the piece to be positioned 2 during the process of pushing the piece to be positioned 2 by the abutting component 1. In addition, the structure of the wheeled component 5 is relatively simple. After the relative positions of the first frame body 53 and the second frame body 52 are adjusted so that the piece to be positioned 2 directly contacts the bearing surface 301, since the wheeled component 5 no longer bears the gravity of the piece to be positioned 2, it is convenient to disassemble the wheeled component 5.

[0055] As Figure 8 shown, in some embodiments, the second frame body 52 is provided with a screw rod 521 extending along the third direction Z. The first frame body 53 is provided with a lapping hole adapted to the screw rod 521. At least part of the screw rod 521 extends from the side of the lapping hole facing the roller 51 into the lapping hole. A first nut 522 is provided on the side of the lapping hole facing the roller 51 and is threadedly connected to the screw rod 521. It can be understood that when only part of the screw rod 521 extends into the lapping hole, under the action of the gravity of the piece to be positioned 2, the side of the lapping hole facing the roller 51 can stably abut against the first nut 522, so that the first frame body 53 can be stably connected to the second frame body 52. By rotating the first nut 522 relative to the screw rod 521, the relative positions of the first frame body 53 and the second frame body 52 can be adjusted. The structure is simple and can achieve the effect of stepless adjustment.

[0056] As Figure 8 shown, in some embodiments, the lapping hole is in the form of a through hole. The screw rod 521 extends out from the side of the lapping hole facing away from the roller 51. A second nut 523 is provided on the side of the lapping hole facing away from the roller 51 and is threadedly connected to the screw rod 521. By rotating the first nut 522 and the second nut 523 respectively in the direction close to the lapping hole, the second frame body 52 can be locked to the first frame body 53, which can further improve the connection stability between the first frame body 53 and the second frame body 52.
