In one embodiment, the connection unit 200 includes a first connection pad 210 and a second connection pad 220, the first connection pad 210 is used for abutting against the power connection pad 202 on the power mechanism 22, and the second connection pad 220 is used for abutting against the driving connection pad 203 on the operation arm 23, so that the power mechanism 22 drives the operation arm 23 through the connection unit 200. At least one of the first connecting plate 210 and the power connecting plate 202 is movable along the abutting direction, and at least one of the second connecting plate 220 and the driving connecting plate 203 is movable along the abutting direction, so that the mounting gap between the connecting unit 200 and the operating arm 23 and the power mechanism 22 is reduced. For example, the first connection disc 210 and the second connection disc 220 are both movable relative to the body 100 in the holding direction. For another example, the first land 210 and the driving land 203 are both movable relative to the body 100 in the holding direction. For another example, the power connection disc 202 and the second connection disc 220 are both movable relative to the body 100 along the abutting direction. For another example, the first connection disc and the second connection disc are immovable in the abutting direction, and the power connection disc and the driving connection disc move in the abutting direction. The movable connection plate along the abutting direction is movable along the abutting direction when the body 100 of the connection mechanism 10 abuts against or is adjacent to the operating arm 23 and/or the power mechanism 22, that is, when the body 100 is basically stationary relative to the operating arm 23 and/or the power mechanism 22, the connection mechanism 10 moves through the connection plate to reduce the installation gap, and the connection plate includes a first connection plate 210, a second connection plate 220, a driving connection plate 203 and a power connection plate 202.

In the embodiment shown in fig. 7, the connection unit 200 is disposed through the mounting groove 130, and both ends of the connection unit extend out of the mounting groove 130, i.e. protrude out of the first mounting wall 110 and the second mounting wall 120, respectively. In other embodiments, the connection unit 200 may also have one end extending out of the mounting groove 130 and the other end located in the mounting groove 130.
In the embodiment shown in fig. 6 to 9, the rotation axes of the first connecting disc 210 and the second connecting disc 220 in the connecting unit 200 substantially coincide, i.e. the center lines of the first connecting disc and the second connecting disc substantially coincide. In other embodiments, the rotation axes of the first connecting disc 210 and the second connecting disc 220 may form an acute angle or a right angle, that is, the first connecting disc and the second connecting disc form an acute angle or a right angle.

As shown in fig. 8, in an embodiment, the first pad 210 and the second pad 220 of the connection unit 200 move independently relative to the body 100, that is, when the first pad 210 moves, the state of the second pad 220 is not affected, and vice versa. Specifically, the connection unit 200 further includes an elastic unit 230, two ends of the elastic unit 230 respectively abut against the first connection disc 210 and the second connection disc 220, so that edge areas of the two connection discs respectively abut against inner surfaces of the first installation wall 110 and the second installation wall 120, that is, when the operation arm 23 and the power mechanism 22 are not connected, the elastic unit 230 is in a compressed state, so as to ensure that the first connection disc 210, the second connection disc 220 and the two installation walls abut against each other. In other embodiments, the elastic unit 230 may be omitted, and in this case, the elastic unit may be replaced by using a connection pad having elasticity.

Specifically, the second land 220 is provided with a receiving hole 250 for receiving the first connecting post 231, the first connecting post 231 is received in the receiving hole 250 and abuts against the bottom surface of the receiving hole 250, so that the elastic unit 230 is more stably connected with the second land 220, and the second connecting post 232 abuts against the first land 210. In other embodiments, the receiving holes may be opened on the first connecting tray 210, or both the receiving holes are opened on the first connecting tray 210, wherein the receiving holes are used for receiving the first connecting posts 231 or the second connecting posts 232. For example, the first land 210 has a receiving hole, one end of the first connecting post 231 or the second connecting post 232 is received in the receiving hole, and the other end abuts against the second land 220. For another example, the first land 210 and the second land 220 are both provided with receiving holes for receiving the first connecting posts 231, at this time, the first connecting posts 231 of part of the connecting unit 200 are received in the receiving holes of the first land 210, the second connecting posts 232 abut against the second land 220, the first connecting posts 231 of part of the connecting unit 200 are received in the receiving holes of the second land 220, and the second connecting posts 232 abut against the first land 210.

In one embodiment, the first connecting plate is movable relative to the body, and the power connecting plates can be either stationary relative to the first connecting plate, i.e. movable therewith, or movable relative to each other, e.g. as shown in fig. 10 and 11, the power connecting plates can slide along the first mounting position to adjust the coaxiality. In one embodiment, the first interface disc is non-translatable relative to the body, and the power interface disc is moveable relative to the body and the first interface disc. For example, the power connection disc is non-translatable relative to the power body, and it slides along the first mounting location to be movable relative to the body and the first connection disc. For another example, the power connection disc is movable relative to the body and is slidable along the first mounting location.
When the connecting mechanism 10 having the connecting unit 200 is connected to the corresponding operating arm 23 and the power mechanism 22, at least one of the connecting plates abutting against each other is movable relative to the body, so as to adjust the coaxiality between the driving connecting plate 203 and the power connecting plate 202, thereby enabling the operation and control of the operating arm 23 to be more accurate and prolonging the service life.
It should be noted that, when the first connection disc and the second connection disc of the connection mechanism are respectively movable along the first direction and the second direction relative to the body, the first connection disc 210 and the second connection disc 220 can move independently or synchronously. For example, the first connecting plate 210 and the second connecting plate 220 are slidably connected in the adjusting direction so that they can move relatively. In this case, the first mounting position and the second mounting position may be tapered grooves. In other embodiments, the first connecting plate 210 and the second connecting plate 220 may also move synchronously, and the connecting unit moves in the mounting slot for adjustment.
Fig. 12 to fig. 14 are schematic structural diagrams of an embodiment of a connecting mechanism 10 and a connecting unit 200 according to the present invention.
In an embodiment, the first connection pad 210 and the second connection pad 220 are both movable relative to the body, specifically, the first connection pad 210 is movable along a first direction limited by the first installation position 211, the second connection pad 220 is movable relative to the body along a second direction limited by the second installation position 221, both the first direction and the second direction are perpendicular to the rotation axis, and projections of both directions on the first connection pad 210 or the second connection pad 220 intersect, that is, both directions are arranged in a non-parallel manner.
As shown in fig. 12, in an embodiment, the first connection pad 210 and the second connection pad 220 of the connection unit are both received in the mounting groove 130 of the body and are movable in the mounting groove 130 along a direction perpendicular to the rotation axis thereof, specifically, a gap is provided between each connection pad and a side wall of the mounting groove so as to be movable. For example, the first connecting disc and the second connecting disc can translate along the plane of the surfaces, the rotating shaft of the first connecting disc is perpendicular to the first connecting disc, and the rotating shaft of the second connecting disc is perpendicular to the second connecting disc. When the connection unit 200 is connected to the driving connection pad 203, the connection unit 200 can only move in the first direction and the second direction due to the limitation of the first installation position 211 and the second installation position 221.
In other embodiments, the mounting position may be at least a partial disk region on the connecting disk, in which case a plurality of connecting disks may be magnetically connected, and the coaxiality is adjusted by a gap between the connecting disk and the body.
The first connecting disc and the second connecting disc can also be static relative to the body along the plane where the first connecting disc and the second connecting disc are located, namely the two connecting discs cannot translate along the plane where the first connecting disc and the second connecting disc are located, and at the moment, the power connecting disc and the driving connecting disc can translate relative to the body. In one embodiment, the first connecting disc is provided with a first mounting position so that the first connecting disc and the power connecting disc connected with the first connecting disc can move relatively along a first direction; the second connecting disc is provided with a second mounting position so that the second connecting disc and the driving connecting disc connected with the second connecting disc can move relatively along a second direction.
In the embodiment shown in fig. 13, the first mounting locations 211 and the second mounting locations 221 are strip-shaped holes, wherein the first direction is an extending direction of the first mounting locations, and the second direction is an extending direction of the second mounting locations. At this time, the power connection pad 202 and the driving connection pad 203 are provided with corresponding column structures, such as the mounting columns 214, to be correspondingly connected with the first mounting position and the second mounting position, and the column structures are movable along the strip holes in the strip holes to adjust the coaxiality, that is, the first connection pad and the power connection pad are relatively movable, and the second connection pad and the driving connection pad are relatively movable. In other embodiments, only one of the mounting locations may be a strip-shaped hole, or the two mounting locations may also be in other shapes, for example, a columnar structure, where the power connection disc and the driving connection disc are provided with corresponding strip-shaped holes.
In other embodiments, for example, the body may have a plurality of connection units, and in this case, the coaxiality is adjusted mainly by moving the driving land and the power land in the mounting position, and the gap between the connection unit and the side wall of the mounting groove of the body is adjusted mainly when the plurality of connection units are connected so that the plurality of connection units are connected to the corresponding land. That is, the gap between the connection unit and the mounting groove can be adjusted for coaxiality, and the position between the connection units can be adjusted, so that the connection units are correspondingly arranged and connected with the corresponding driving connection disc and the corresponding power connection disc.
In one embodiment, the first mounting locations 211 and the second mounting locations 221 penetrate through the side surface of the periphery of the first land 210 or the second land 220 where the mounting locations are disposed, so as to facilitate processing. In other embodiments, only the first mounting position may extend through the side of the first land, or only the second mounting position may extend through the side of the periphery of the second land 220. Alternatively, the two mounting locations may not extend through the side of the connecting pad.
In addition, in an embodiment, the first mounting position 211 and the second mounting position 221 are tapered holes, so that mounting gaps among the plurality of connecting discs can be further reduced, and the first mounting position and the second mounting position can be more tightly mounted with the power connecting disc and the driving connecting disc. In other embodiments, the two mounting locations may be non-tapered holes, or only the first mounting location or the second mounting location may be tapered holes.
In an embodiment, the first land 210 and the second land 220 are disposed opposite to each other, and the first mounting location 211 and the second mounting location 221 are respectively located on surfaces of the first land 210 and the second land 220 opposite to each other. The first mounting positions 211 include two, and the first direction is an arrangement direction of the two first mounting positions 211; the second mounting locations 221 include two, and the second direction is an arrangement direction of the two second mounting locations 221. In other embodiments, the first direction and the second direction may be other directions. For example, the first direction is a direction perpendicular to the arrangement direction of the plurality of first mounting locations 211, and similarly, the second direction is a direction perpendicular to the arrangement direction of the plurality of second mounting locations 221.
In an embodiment, an intersection point of the first direction and the second direction projected on the first land 210 or the second land 220 is located on the first land 210 or the second land 220. For example, the intersection point is located in a central region of the first land 210 and/or the second land 220; for another example, the first land 210 and the second land 220 are both centrosymmetric, and the intersection point is located at the symmetric center of the first land 210 and/or the second land 220. In other embodiments, the intersection point may be located outside the first land 210 or the second land 220.
In one embodiment, the first direction and the second direction are disposed non-parallel, for example, the first direction and the second direction are orthogonal. For another example, the first direction forms an acute angle with the second direction. In other embodiments, the first direction may be the same as the second direction.
In one embodiment, the first direction is perpendicular to the rotation axis of the first connecting disc, and/or the second direction is perpendicular to the rotation axis of the second connecting disc. I.e. the connection disc, which is translatable relative to the body, is movable in a direction perpendicular to the axis of rotation. In other embodiments, the first direction may form an acute angle with the first land, and the second direction may form an acute angle with the second land. It should be noted that the first direction and the second direction are both non-holding directions.
Please refer to fig. 14, which is a schematic structural diagram of the first connection pad 210 according to an embodiment of the present invention.
In one embodiment, the first land 210 and the second land 220 are connected to each other. Specifically, protruding portions 260 extend from the first connecting disc 210 and the second connecting disc 220, at least two protruding portions 260 are disposed on the first connecting disc 210 and/or the second connecting disc 220 at intervals, and a recessed area 270 is formed by two adjacent protruding portions 260. The convex part 260 of the first connecting disc 210 is accommodated in the concave region 270 of the second connecting disc 220, and the convex part 260 abuts against two adjacent convex parts 260 forming the concave region 270 for accommodating the convex part 260; and/or the protruding portion 260 of the second land 220 is received in the recessed area 270 of the first land 210, and the protruding portion 260 abuts against two adjacent protruding portions 260 forming the recessed area 270 for receiving the protruding portion 260. In an embodiment, when the first land and/or the second land has/have the receiving hole 250, the receiving hole 250 is opened on the protrusion 260.
In this embodiment, the first connection disc 210 and the second connection disc 220 each have two protrusions 260 and are each formed with two recessed regions 270, for example, the two protrusions are oppositely disposed. The two protruding portions 260 of the first connecting disc 210 are respectively accommodated in the second connecting disc 220 and the two corresponding recessed areas 270 thereof, and the two protruding portions 260 of the second connecting disc 220 are respectively accommodated in the first connecting disc 210 and the two corresponding recessed areas 270 thereof. And the first mounting position and the second mounting position are positioned in the area of the connecting disc with the convex part. In other embodiments, the number of the protruding portions 260 and the number of the recessed areas 270 may be different, for example, two protruding portions 260 are provided on the first land 210 to form a recessed area 270, and one protruding portion 260 is provided on the second land 220 and is received in the recessed area 270 of the first land 210. Note that, when the land has the convex portion 260, the mounting site is located in a region of the land having the convex portion 260.
Further, the concave region 270 for receiving the protrusion 260 is matched with the protrusion 260, so that the first connection disc 210 and the second connection disc 220 are buckled. That is, the protruding portion 260 of the first land 210 matches the corresponding recessed region 270 of the second land 220, and the recessed region 270 matches the corresponding protruding portion 260 of the second land 220. When the protruding portion 260 is plural, at least one protruding portion 260 matches with the corresponding recessed region 270. Thus, the first connecting plate 210 and the second connecting plate 220 can be connected without other connecting parts.
In one embodiment, the protrusion 260 has a first side surface 261 and two second side surfaces 262 adjacent to the first side surface 261. Wherein the first side surface 261 of the protruding portion 260 of the first connecting disc 210 is adjacent to and extends along the periphery of the first connecting disc 210, and the first side surface 261 is flush with the corresponding area of the periphery of the first connecting disc 210. In this embodiment, the first connecting disc is a circular disc, and the first side surface is an arc surface at this time. The two second side surfaces 262 are both located on the same side of the first side surface 261, and an included angle is formed between the two second side surfaces 262 or between the two second side surfaces 262, and the included angle is not 0 degree or 360 degrees, that is, the planes of the two second side surfaces 262 are not overlapped. It should be noted that, in other embodiments, two second side surfaces may be located on two sides of the first side surface. In this embodiment, the protruding portion 260 of the second connecting pad 220 is the same as the first connecting pad 210, and will not be repeated here. In other embodiments, the protruding portion 260 of the second connecting pad 220 and the first connecting pad 210 may have different structures.
Further, two opposite second side surfaces 262 of the two protrusions 260 forming the recessed area 270 on the first connection disc 210 are correspondingly abutted with two second side surfaces 262 of the protrusions 260 on the second connection disc 220 received in the recessed area 270, so that the two connection discs are fastened. I.e. the second side surfaces 262 of the two coupling discs abut correspondingly.
In one embodiment, the protruding portions 260 and the recessed regions 270 of the first land 210 and/or the second land 220 are circumferentially distributed. For example, the protruding portions 260 of the first connecting disc 210 and the second connecting disc 220 are both disposed oppositely. The connecting discs that are circumference distribution make two connecting discs more accurate when installing, and then when the connecting disc removed through the installation position that is located above that, the shift position was more accurate, improved operating arm 23 and power unit's axiality. In other embodiments, the protrusions 260 on the connecting disc may also be distributed in a central symmetry manner, for example, the connecting disc has a central symmetry structure.
In one embodiment, the first land 210 and the second land 220 are identical in structure. When the two connecting discs are connected in a buckling manner, the protruding part 260 of one connecting disc is accommodated in the recessed area 270 of the other connecting disc, and an included angle is formed between the first direction limited by the first mounting position 211 and the second direction limited by the second mounting position 221. Thus, not only the structure of the connecting mechanism 10 is simplified, but also the production efficiency can be improved.
In other embodiments, the first connection pad 210 and the second connection pad 220 may not be connected to the concave region 270 through the protrusions 260 matching with each other. For example, the first and second connection discs 210, 220 are connected to each other and by threaded fasteners, at which time the two connection discs may still have the protrusions 260 and the protrusions 260 of the two connection discs abut each other for positioning. For another example, the connecting discs are provided with a buckling structure so that the two connecting discs are buckled.
It should be noted that when the power connection disc of the power mechanism is movable relative to the body in the first direction and the driving connection disc of the operating arm is movable relative to the body in the second direction, the power mechanism may have substantially the same structure as the connection disc of the connection mechanism and its related structure.
For example, the power coupling plate of the power mechanism is movable relative to the body in a first direction. The power mechanism is provided with a power body, the power body is abutted against the body of the connecting mechanism, the power connecting disc is arranged on the power body and provided with a first mounting position, and the power connecting disc is movable relative to the power body along a first direction limited by the first mounting position; and/or the power connecting disc and the first connecting disc can move relatively along the first direction limited by the first mounting position. Further, the power connection disc comprises two first installation positions, and the first direction is the arrangement direction of the first installation positions. Or the first mounting position is a strip-shaped hole, and the extending direction of the first mounting position is the first direction. In one embodiment, the first mounting location is a hole structure and penetrates through the side surface of the periphery of the power connecting disc where the mounting location is arranged. In one embodiment, the first direction is perpendicular to the axis of rotation of the power connection pad.
For another example, the drive interface plate of the operating arm is movable relative to the body in the second direction. The operation arm is provided with a driving body, the driving body is abutted against the body of the connecting mechanism, the driving connecting disc is arranged on the driving body, the driving connecting disc is provided with a second mounting position, and the driving connecting disc is movable relative to the driving body along a second direction limited by the second mounting position; and/or the driving connecting disc and the second connecting disc are relatively movable along a second direction of a second positioning limit. Further, the driving connecting disc comprises two second mounting positions, and the second direction is the arrangement direction of the second mounting positions. Or the second mounting position is a strip-shaped hole, and the extending direction of the second mounting position is the second direction. In one embodiment, the second mounting location is a hole structure and penetrates through a side surface of the periphery of the driving connecting disc where the mounting location is arranged. In one embodiment, the second direction is perpendicular to the rotation axis of the driving land.
The above embodiments describe specific schemes for adjusting the coaxiality and the installation clearance when the connecting mechanism is connected with the operating arm and the power mechanism. In other embodiments, at least one of the connection mechanism, the operation arm, and the power mechanism may be capable of adjusting the coaxiality and the installation gap when the connection mechanism, the operation arm, and the power mechanism are connected. For example, the first connection plate and/or the second connection plate can move along the abutting direction and can move relative to the body along the first direction and/or the second direction. For another example, the first connecting disc can move along the abutting direction, and the second connecting disc can move along the second direction relative to the body; or the second connecting disc can move along the abutting direction, and the first connecting disc can move along the first direction relative to the body. For another example, the first connecting plate and the second connecting plate are both movable along the abutting direction and movable relative to the body along a direction perpendicular to the rotating shaft. For another example, the first connection disc and/or the power connection disc is movable along the abutting direction and is movable relative to the body along a direction perpendicular to the rotation axis; the second connecting disc and/or the driving connecting disc can move along the abutting direction and can move relative to the body along the direction vertical to the rotating shaft.
In this case, the first land and the second land may move independently or synchronously in the moving direction. For example, the first and second connection plates move independently in the holding direction and move synchronously in a direction perpendicular to the rotation axis. For another example, the first and second connection plates move independently in the abutting direction and in the direction perpendicular to the rotation axis.
The structure of each land is the same as that of the land and the related structure in the above embodiments, and will not be repeated here.
Fig. 15 is a partial schematic structural diagram of a slave operating device according to an embodiment of the present invention.
The slave operation device 2 includes: a connecting mechanism 10, an operating arm 23 and a power mechanism 22. Wherein, the connecting mechanism 10 is provided with a through hole 150; the power mechanism 22 has a first connecting surface 204 abutting against the connecting mechanism 10, and the first connecting surface 204 is provided with a first detecting part 205; the operating arm 23 has a second connecting surface 206 abutting against the connecting mechanism 10, the second connecting surface 206 is provided with a second detecting portion 207, and the first detecting portion 205 and/or the second detecting portion 207 are/is accommodated in the through hole 150 and are disposed adjacent to or abut against each other. The first detection portion 205 and/or the second detection portion 207 are further provided with a sensor 208 for detecting a distance between the first detection portion 205 and the second detection portion 207 to obtain an abutting state of the first connection surface 204, the second connection surface 206 and the connection mechanism. Wherein, the power connection pad is disposed on the first connection face 204, and the driving connection pad is disposed on the second connection pad.
When the operation arm 23 and the power mechanism 22 are connected to the connection mechanism, if the distance between the first detection portion 205 and the second detection portion 207, which is detected by the sensor 208, is within a preset range, the first connection surface 204 abuts against the first installation wall, and the second connection surface 206 abuts against the second installation wall, at this time, the sensor 208 sends abutting information to perform subsequent operations; if the first connection surface 204 and/or the second connection surface 206 are not abutted against the corresponding mounting wall of the connection mechanism, the distance detected by the sensor 208 is out of the preset range, and at this time, the sensor 208 is not triggered to send the abutting information.
The slave operation device having the operation arm 23 and the power mechanism 22 can detect the connection condition between the power mechanism 22 and the first connection surface 204 and the second connection surface 206 by the sensor 208 penetrating the through hole 150, without providing a sensor 208 near each connection surface to detect the contact condition between the first connection surface 204 and the first mounting wall and between the second connection surface 206 and the second mounting wall. Therefore, the design is simplified, and the production efficiency and the stability are further improved.
In one embodiment, the first detecting portion 205 and the second detecting portion 207 are both accommodated in the through hole 150. Specifically, the first detection portion 205 and the second detection portion 207 are both of a columnar structure, and end surfaces of free ends thereof are disposed opposite to each other and are both accommodated in the through hole 150, wherein the free ends refer to end portions connected to the sensor 208 or used for approaching the sensor 208. At this point, the sensor 208 is positioned within the through-hole 150.
In other embodiments, the first detecting portion 205 may also be disposed through the through hole 150, the second detecting portion 207 may be a groove structure, specifically, the free end of the first detecting portion 205 extends out of the through hole 150, or is located in the through hole 150 and is close to the edge area of the through hole 150, the sensor 208 is disposed on the first detecting portion 205 and extends out of the through hole 150, or is located in the through hole 150 and is used for detecting the distance between the sensor 208 and the bottom surface of the groove structure, or the sensor 208 is disposed on the bottom surface of the groove structure and is used for detecting the distance between the sensor 208 and the first detecting portion 205. The second detecting portion 207 may also be disposed through the through hole 150, and the first detecting portion 205 is a groove structure, which is similar to the above embodiments and will not be repeated here.
In one embodiment, the first detecting portion 205 includes a plurality of through holes 150, the second detecting portion 207, and the sensor 208. For example, the number of the first detecting portions 205 is three, and the number of the through holes 150 and the number of the second detecting portions 207 are three, and the through holes 150 are also distributed in a triangular shape, so that the first detecting portions 205 and/or the second detecting portions 207 are inserted into the through holes 150. In the case where there are a plurality of first detecting portions 205, the lengths of the plurality of first detecting portions 205 may be different, that is, the distances between the end surfaces of the free ends of the plurality of first detecting portions 205 and the first connecting surface 204 are different, and the second detecting portions 207 are correspondingly provided. For example, one of the first detecting portions 205 is located in the through hole 150, and one of the first detecting portions 205 protrudes from the through hole 150.
In one embodiment, the first detecting portion 205 and/or the second detecting portion 207 are matched with the through hole 150 for positioning during installation, and in this case, the positioning hole can be omitted and replaced by the through hole 150.
In one embodiment, the sensor 208 is a distance sensor 208 and/or a pressure sensor 208. For example, the number of the sensors 208 is multiple, and all the sensors 208 are distance sensors 208, and when the abutting information fed back by the sensors 208 is within the preset range, the operation arm 23, the power mechanism 22, and the connection mechanism meet the connection requirement, so as to perform the subsequent operation. For another example, the sensors 208 may be partially pressure sensors 208 and partially distance sensors 208, and when the abutting information fed back by the pressure sensors 208 and the distance sensors 208 are both within the preset range, the operating arm 23, the power mechanism 22, and the connecting mechanism meet the connection requirement. As another example, sensor 208 may detect both pressure information and distance information.

In an embodiment, the power mechanism 22 and the operating arm 23 are further provided with an electromagnet assembly 209, which is used for connecting the power mechanism 22, the connecting mechanism and the operating arm 23 according to the information fed back by the sensor 208.

Specifically, in one embodiment, the electromagnet assembly includes a magnetic portion 209A and an attraction portion 209B, and the attraction portion 209B is made of a material that can be attracted by the magnetic portion. The magnetic portion 209A is disposed on the first connection surface 204 or the second connection surface 206, and the magnetic portion 209A and/or the attraction portion 209B are disposed through the connection mechanism 10 and magnetically connected to each other. For example, the connection mechanism has a receiving through hole 160, and both the magnetic portion 209A and the attraction portion 209B are received in the receiving through hole 160, that is, the magnetic portion and the attraction portion are magnetically connected in the receiving through hole 160. For another example, the magnetic portion is disposed on the first connecting surface 204 and penetrates the receiving through hole 160, and the attracting portion is disposed on the second connecting surface 206 and is flush with the second connecting surface 206.
In other embodiments, the power mechanism 22, the operating arm 23, and the connecting mechanism may be provided with an electromagnet assembly for connecting the power mechanism 22, the connecting mechanism, and the operating arm 23 according to the information fed back by the sensor 208. Specifically, the electromagnet assembly includes a plurality of magnetic portions and a plurality of attracting portions, wherein the magnetic portions are disposed on the connecting mechanism, and the attracting portions are disposed on the first connecting surface 204 and the second connecting surface 206, respectively, so as to magnetically connect the operating arm 23, the connecting mechanism, and the driving mechanism. For example, the connection mechanism has a receiving through hole 160, and the magnetic portion is disposed in the receiving through hole 160, and two surfaces of the magnetic portion facing the first connection surface 204 and the second connection surface 206 are respectively magnetically connected to the attraction portions on the first connection surface 204 and the second connection surface 206, so as to connect the operation arm 23, the power mechanism 22, and the connection mechanism to each other.
In one embodiment, the plurality of sensors 208 is distributed around the electromagnet assembly. For example, the magnetic portion is disposed in the middle region of the connection mechanism, the attraction portion is disposed on the first connection surface 204 and the second connection surface 206, the first detection portion 205 is disposed on the first connection surface 204 around the attraction portion, and the sensor 208 is disposed on the first detection portion 205.
In each of the above embodiments, the sensor 208 may be used to detect the contact state of the connection surface, and the power mechanism 22, the connection mechanism, and the operation arm 23 may be connected by an electromagnet assembly, which will not be described again.
As shown in fig. 17 to 19, the plurality of lands may be connected in other manners.
In one embodiment, the slave operation device 2 includes: a connecting mechanism 10, a power mechanism 22 and an operating arm 23. Specifically, the power mechanism 22 has a power connection disc 202; the operation arm 23 has a drive land 203; the connection mechanism 10 has a body 100 and a connection unit 200 provided on the body 100, the connection unit 200 has a first land 210, a second land 220, a power land 202 connected to the first land 210, a driving land 203 connected to the second land 220, and the power land 202 magnetically connected to the driving land 203 so that the power land 202 drives the driving land 203 and thus the operating arm 23 to perform a desired operation.
It should be noted that the power connection pad 202 may rotatably drive the driving connection pad 203, and the connection unit 200 may be rotatable with respect to the body 100, and the power connection pad 202 may also linearly drive the driving connection pad 203, and the connection unit 200 may be movable with respect to the body 100 in a driving direction. The connecting pads and the connecting unit 200 can also move along the abutting direction and/or move along the first direction/the second direction in the above embodiments, for example, the first connecting pad 210 and the second connecting pad 220 can move relatively to reduce the installation gap.
The power land 202 is magnetically connected to the driving land 203, and the power land 202 may be directly magnetically connected to the driving land 203, or the power land 202 may be magnetically connected to the driving land 203 via the connection unit 200. Specifically, at least one of the driving land 203, the power land 202, and the connection unit 200 has magnetism so that the power land 202 drives the driving land 203.
As shown in fig. 17, in one embodiment, power land 202 is magnetically coupled to drive land 203 via coupling unit 200. The connection unit 200 has magnetism, and the first connection pad 210 and the second connection pad 220 are respectively magnetically connected with the power connection pad 202 and the driving connection pad 203. In other embodiments, the driving pad 203 may be magnetic to magnetically couple with the second pad 220, and/or the power pad 202 may be magnetic to magnetically couple with the first pad 210.
In one embodiment, the first connecting plate 210 is in communication with the second connecting plate 220, and the driving connecting plate 203 and the power connecting plate 202 are disposed in abutting or adjacent to each other through a communication area to be magnetically connected.
