[0062] Embodiment 1

[0063] The first embodiment of the present application provides a magnetic base 100, which is used to connect the robot body 200 and the track 300. The magnetic base 100 is connected with the robot body 200 to form a robot. Figures 1 to 3 The magnetic base 100 can be quickly fixed and disassembled on the track 300, and the magnetic base 100 can also slide on the track 300 to change the position of the robot body 200, quickly adapt to various working positions, and improve adaptability.

[0064] It should be noted that the track 300 is an I-beam structure, and the magnetic base 100 can slide on the track 300 .

[0065] In the examples of this application, see Figure 4 As shown, the magnetic base 100 includes an adjustment component 110 and a fixed seat 120. The fixed seat 120 is used to connect with the track 300 and the robot body 200. The adjustment component 110 is used to adjust the fixed relationship between the fixed seat 120 and the track 300, that is, the adjustment component 110 can control whether the fixed seat 120 is in contact with the track 300 or the fixed seat 120 is suspended on the track 300.

[0066] Among them, see Figure 5 As shown, the adjustment assembly 110 includes an adjustment handle 111, a connecting member 112 and a moving seat 113. The adjustment handle 111 is connected to the moving seat 113 via the connecting member 112.

[0067] In the embodiment of the present application, the movable seat 113 includes a movable body 1130 and a rolling portion 1131 disposed on the movable body 1130 , at least a portion of the rolling portion 1131 protrudes from the surface of the movable body 1130 , and the rolling portion 1131 can rotate relative to the movable body 1130 .

[0068] In the examples of this application, see Figure 6 and Figure 7 As shown, the fixed seat 120 includes a fixed body 121 and a sliding block 122, the sliding block 122 is arranged on the fixed body 121, and the sliding block 122 is arranged on one side of the mobile body 1130, and corresponds to the rolling part 1131 on the mobile body 1130. The rolling part 1131 can slide on the sliding block 122 to adjust the position of the sliding block 122, thereby adjusting the position of the fixed body 121.

[0069] It is understandable that the movable body 1130 may be located at the lower side, upper side, left side or right side of the sliding block 122 , as long as the rolling portion 1131 can slide on the sliding block 122 and adjust the position of the sliding block 122 .

[0070] In the examples of this application, see Figures 8 to 10 As shown, the sliding block 122 includes a sliding position 1220, and the cross-sectional area of ​​the sliding position 1220 gradually increases in the direction from the moving body 1130 to the sliding block 122. The sliding position 1220 has a plane 1221 and an inclined surface 1222 connected to each other, and the plane 1221 is arranged on the side of the inclined surface 1222 close to the moving body 1130, that is, the sliding position 1220 has a trapezoidal structure.

[0071] In the examples of this application, see Figure 8 As shown, the sliding position 1220 includes a plane 1221 and two inclined surfaces 1222 located on opposite sides of the plane 1221 . The sliding position 1220 is an isosceles trapezoidal structure, and the two inclined surfaces 1222 and the plane 1221 have the same included angle.

[0072] The connecting member 112 can move linearly when the adjusting handle 111 moves in a circular motion, and the moving body 1130 can move along with the connecting member 112, and the moving direction of the moving body 1130 is the same as that of the connecting member 112. Driven by the moving body 1130, the rolling part 1131 on the moving body 1130 also moves along with the connecting member 112. During the movement, the rolling part 1131 can move from the inclined surface 1222 of the sliding position 1220 to the plane 1221 of the sliding position 1220, or from the plane 1221 of the sliding position 1220 to the inclined surface 1222 of the sliding position 1220. Figure 6 to Figure 7 As shown, and Figure 9 to Figure 8As shown, when the rolling portion 1131 moves from the inclined surface 1222 of the sliding position 1220 to the plane 1221 of the sliding position 1220, the distance between the plane 1221 of the sliding position 1220 and the surface of the mobile body 1130 gradually increases, and the sliding block 122 gradually moves to the side away from the mobile body 1130, and the fixed body 121 will move together with the sliding block 122 to lift the fixed body 121, increase the distance between the fixed body 121 and the track 300, and make the fixed body 121 suspended on the track 300. Figure 7 to Figure 6 As shown, and Figures 8 to 9 As shown, when the rolling portion 1131 moves from the plane 1221 of the sliding position 1220 to the inclined surface 1222 of the sliding position 1220, the distance between the plane 1221 of the sliding position 1220 and the surface of the movable body 1130 gradually decreases, and the fixed body 121 moves toward the side close to the movable body 1130 along with the sliding block 122, thereby reducing the distance between the fixed body 121 and the track 300. When the rolling portion 1131 slides to the edge of the inclined surface 1222 away from the plane 1221, the fixed body 121 contacts the track 300.

[0073] That is, the present application scheme controls the moving track of the connecting member 112 and the moving body 1130 by adjusting the handle 111, so that the rolling part 1131 slides from the plane 1221 or the inclined surface 1222 of the sliding position 1220 to the inclined surface 1222 or the plane 1221 of the sliding position 1220, so as to achieve the effect of lowering or lifting the fixed body 121, thereby achieving the effect of connecting the fixed body 121 with the track 300 or separating the fixed body 121 from the track 300. Through this scheme, the fixed body 121 can be quickly connected to the track 300, and the fixed body 121 can be quickly separated from the track 300, which is convenient for adjusting the position of the robot, and can be used with a variety of welding production lines, with strong compatibility.

[0074] It is understandable that the sliding block 122 can be disposed on the side of the fixed body 121, on the top of the fixed body 121, or on the bottom of the fixed body 121. Correspondingly, the movable seat 113 can also be disposed on the side, top or bottom of the fixed body 121 to cooperate with the sliding block 122.

[0075] In the embodiment of the present application, the sliding block 122 is arranged on the side of the fixed body 121, and the movable body 1130 is located below the sliding block 122, so that when moving from the plane 1221 to the inclined surface 1222, the weight of the fixed body 121 itself can be utilized to improve the sliding convenience of the rolling part 1131 on the inclined surface 1222.

[0076] It is understandable that the moving direction of the connecting member 112 and the movable body 1130 can be horizontal or oblique, as long as the height of the fixed body 121 can be raised and lowered.

[0077] In the embodiment of the present application, the movable body 1130 and the connecting member 112 slide in the horizontal direction under the action of the adjusting handle 111 .

[0078] It is worth mentioning that see Figure 7 As shown, in order to improve the stability of lowering and lifting the fixed body 121, the fixed seat 120 includes a plurality of sliding blocks 122, which are respectively located on two opposite sides of the fixed body 121. The sliding blocks 122 on the two opposite sides are symmetrically arranged with each other, and the structures of the plurality of sliding blocks 122 are the same.

[0079] In the examples of this application, see Figure 5 As shown, a plurality of rolling parts 1131 cooperating with the sliding block 122 are provided on the mobile body 1130. The mobile body 1130 is arranged around the fixed body 121, and the mobile body 1130 adopts a segmented structure, which includes a first segment, a second segment and a third segment. The first segment is used to be fixedly connected with the connecting member 112 so as to move along with the connecting member 112. The second segment and the third segment are respectively arranged on opposite sides of the fixed body 121. The second segment is connected with the third segment through the first segment, and the first segment is fixed to the second segment and the third segment by fixing structures such as screws and rivets.

[0080] In the embodiment of the present application, the extension direction of the first segment is perpendicular to the extension direction of the second segment. The rolling portion 1131 is disposed on the second segment and the third segment, and the rolling portions 1131 on the second segment and the third segment are symmetrically disposed.

[0081] For example, see Figure 5 As shown, the mobile body 1130 is provided with four rolling parts 1131, and two rolling parts 1131 are respectively provided on the second section and the third section, and the rolling parts 1131 on the second section and the rolling parts 1131 on the third section are symmetrically arranged. Correspondingly, two sliding blocks 122 are respectively provided on opposite sides of the fixed body 121, and the sliding position 1220 in the sliding block 122 cooperates with the rolling part 1131 above the mobile body 1130. When the rolling part 1131 moves in the horizontal direction, the rolling part 1131 will slide on the inclined surface 1222 or the plane 1221 on the sliding position 1220 to lower or lift the sliding block 122, thereby lowering or lifting the fixed body 121.

[0082] It is worth mentioning that an arc segment is provided on the first section, and the arc segment can play a role in avoiding the fixed body 121 during the horizontal movement.

[0083] In the examples of this application, see Figure 5 As shown, in order to facilitate the assembly of this rolling part 1131, a mounting groove is opened on the movable body 1130, a part of the rolling part 1131 is arranged in this mounting groove, and the other part protrudes from the top surface of the movable body 1130, and in order to facilitate the rotation of the fixing part in this mounting groove, there is a gap between this rolling part 1131 and the bottom wall 132 of the mounting groove.

[0084] See also Figure 5 As shown, in order to fix the rolling part 1131 in the installation groove, the moving seat 113 also includes a protruding block, which is protruding from the surface of the moving body 1130 and is located on opposite sides of the top surface of the installation groove. The rolling part 1131 can adopt a roller structure or other rolling types, such as a spherical structure.

[0085] It should be noted that the height of the rolling portion 1131 is higher than the height of the protruding block, so that the rolling portion 1131 contacts the plane 1221 or the inclined surface 1222 on the sliding position 1220 , thereby ensuring that the rolling portion 1131 can adjust the height of the sliding block 122 .

[0086] In addition, the axial direction of the rolling portion 1131 is perpendicular to the moving direction of the second section or the third section, that is, the axial direction of the rolling portion 1131 is perpendicular to the arrangement direction of the inclined surface 1222 and the plane 1221. This allows the rolling portion 1131 to slide from the plane 1221 to the inclined surface 1222 and from the inclined surface 1222 to the plane 1221, thereby lowering and lifting the sliding block 122.

[0087] In the examples of this application, see Figure 4 As shown, in order to ensure the aesthetics of the magnetic base 100, the magnetic base 100 further includes a base housing 130, and the base housing 130 includes a top wall 131, a bottom wall 132, and a side wall 133. The side wall 133 is arranged around the top wall 131 and the bottom wall 132, and forms an accommodation space between the top wall 131 and the bottom wall 132. The movable base 113, part of the connector 112, and part of the fixed base 120 are arranged in the accommodation space.

[0088] In order to enable the adjustment handle 111 to drive the connecting member 112 to move, the adjustment handle 111 and the connecting member 112 can be connected by a hinge or by gear meshing. Of course, other connection methods can also be used as long as the adjustment handle 111 can drive the connecting member 112 to move linearly when making a circular motion.

[0089] In the examples of this application, see Figure 5 As shown, the adjustment handle 111 is hingedly connected to the connecting member 112 .

[0090] In the examples of this application, see Figure 5 As shown, the connecting member 112 includes a moving shaft 1120 and a sleeve 1121. The adjusting handle 111 has a first clamping portion 1110 and a gripping portion 1111 connected to each other. The first clamping portion 1110 has a clamping space. One end of the moving shaft 1120 is arranged in the clamping space and connected to the moving shaft 1120 through a rotating shaft, and the other end is fixedly connected to the first section. The sleeve 1121 is sleeved on the outer side of the moving shaft 1120, and the moving shaft 1120 can slide relative to the sleeve 1121. The first clamping portion 1110 and the sleeve 1121 are also clamped and connected. When the first clamping portion 1110 follows the gripping portion 1111 to perform a circular motion, the moving shaft 1120 can slide in and out of the hole of the sleeve 1121 to push and pull the moving body 1130, thereby controlling the moving body 1130 to slide in the axial direction of the moving shaft.

[0091] It should be noted that a portion of the sleeve 1121 is disposed in the accommodating space, and another portion is disposed outside the accommodating space, and the sleeve 1121 is fixedly connected to the side wall 133 to prevent the sleeve 1121 from moving during the movement of the movable shaft 1120, thereby ensuring that the movable shaft 1120 slides in the sleeve 1121.

[0092] In addition, in order to facilitate the shaft sleeve 1121 to pass through the side wall 133 and be hingedly connected to the first clamping portion 1110, a through hole is provided on the side wall 133.

[0093] In the examples of this application, see Figure 5 As shown, in order to ensure the connection stability between the adjustment handle 111 and the connecting member 112, hinges are provided on the upper and lower sides of the first clamping portion 1110, and the first clamping portion 1110 is hinged to the shaft sleeve 1121 through the hinges on the upper and lower sides.

[0094] In the embodiment of the present application, in order to ensure that the sleeve 1121 does not move with the moving shaft 1120, the magnetic base 100 further includes an abutment member, which is disposed in the accommodation space and abuts against the side wall 133, so that the moving shaft 1120 can be driven to move along its axial direction when the adjustment handle 111 performs a circular motion. However, since the sleeve 1121 is fixedly connected to the side wall 133, it does not move with the moving shaft 1120, so that the moving shaft 1120 can slide in the sleeve 1121.

[0095] See also Figures 5 to 7As shown, in order to avoid damage to the inner side wall 133 of the base shell 130, the magnetic base 100 also includes a mounting base 140, which is arranged in the accommodating space. The mounting base 140 is arranged at the connection between the side wall 133 and the bottom wall 132, and the mounting base 140 can be fixedly connected to the bottom wall 132 by structures such as bolts or screws. The mounting base 140 is provided with a through hole, which corresponds to the through hole on the side wall 133. The aperture of the through hole is larger than the size of the sleeve 1121 located in the accommodating space, and the aperture of the through hole is smaller than the size of the sleeve 1121 located in the accommodating space and smaller than the size of the abutment, so that the opposite ends of the through hole abut against the sleeve 1121 and the abutment respectively, and the sleeve 1121 is fixedly connected to the mounting base 140.

[0096] This solution is hingedly connected by the adjusting handle 111 and the connecting member 112, so that when the adjusting handle 111 performs a circular motion, the movable shaft 1120 moves along the axial direction of the movable shaft 1120 under the drive of the adjusting handle 111, and slides in the hole of the sleeve 1121. Since the sleeve 1121 is fixed on the mounting base 140, only the movable shaft 1120 moves in its axial direction under the drive of the adjusting handle 111. During the movement of the movable shaft 1120, the movable body 1130 and the rolling part 1131 provided on the movable body 1130 will be driven to move in the axial direction of the movable shaft 1120, so that the rolling part 1131 slides on the plane 1221 and the inclined surface 1222 on the sliding position 1220, so as to lower or lift the fixed body 121, and then control the fixed body 121 to be connected with the track 300 or suspended on the track 300.

[0097] In the examples of this application, see Figure 6 and Figure 7 As shown, the same leakage holes are provided on the top wall 131 and the bottom wall 132. The leakage hole on the top wall 131 is used to leak out a part of the fixed body 121, and the bottom wall 132 is used to leak out the magnetic suction component 123 described below. When the fixed body 121 descends, the magnetic suction component 123 can leak out through the leakage hole, and the magnetic suction component 123 can be magnetically connected to the track 300. When the fixed body 121 rises, the magnetic suction component 123 is retracted into the base shell 130, the magnetic suction component 123 is separated from the track 300, and the magnetic base 100 can slide on the track 300.

[0098] It is worth mentioning that see Fig.10 As shown, in order to prevent the fixed body 121 from deviating during the process of descending and lifting, the magnetic base 100 also includes a first guide member 150, which is extended in the vertical direction and is used to limit the moving path of the fixed body 121 in the vertical direction.

[0099] In the examples of this application, see Figure 6 and Fig.10 As shown, the top wall 131 is provided with through holes and first guide holes 1310 spaced apart from each other, the through holes are used to pass the sliding block 122, and the sliding block 122 passing through the through holes is fixedly connected to the fixed platform 1210 by means of screws, bolts or rivets. The first guide member 150 can slide in the first guide hole 1310.

[0100] In the examples of this application, see Fig.10 As shown, the fixed body 121 includes a fixed platform 1210, which is arranged outside the accommodation space, and the fixed body 121 is located on the side of the top wall 131 away from the side wall 133, so as to be connected with the robot body 200. The robot body 200 can be fixedly connected with the fixed platform 1210 by fixing objects such as screws, rivets or bolts. A second guide hole 1211 is provided on the fixed platform 1210, and the second guide hole 1211 corresponds to the first guide hole 1310. The first guide member 150 is arranged in the first guide hole 1310 and the second guide hole 1211.

[0101] The first guide member 150 may be fixedly connected to the fixed platform 1210 , or may be connected to the top wall 131 , as long as the first guide member 150 can limit the moving path of the fixed body 121 .

[0102] In the examples of this application, see Fig.10 As shown, the first guide member 150 is fixedly connected to the second guide hole 1211. The first guide member 150 includes a guide sleeve 151 and a guide column 152, and the guide sleeve 151 is fixedly arranged in the second guide hole 1211. The guide sleeve 151 includes a sliding hole, one end of the guide column 152 is inserted in the sliding hole and can slide in the sliding hole, and the other end is inserted in the first guide hole 1310. During the lowering and lifting process of the fixed body 121, the first guide member 150 can slide up and down in the first guide hole 1310, the second guide hole 1211 and the sliding hole, so as to limit the moving path of the fixed body 121 and prevent the fixed body 121 from deflecting when moving up and down.

[0103] In the embodiment of the present application, the fixing seat 120 includes two states: a magnetic state and a demagnetized state. The fixing seat 120 also includes a magnetic member 123, which is disposed on a side of the fixing body 121 close to the track 300. In the magnetic state, the magnetic member 123 is magnetically connected to the track 300, and the magnetic member 123 and the track 300 are not easily separated; in the demagnetized state, the magnetic member 123 overlaps the magnetic base 100, that is, there is no magnetism between the magnetic member 123 and the track 300, and the magnetic member 123 and the track 300 are easily separated.

[0104] In the examples of this application, see Figure 7As shown, the fixed seat 120 includes a control handle 124 and a control base 125. The control handle 124 is arranged on the opposite side of the adjustment handle 111, and the control base 125 is arranged between the fixed platform 1210 and the magnetic component 123. The control handle 124 is connected to the control base 125, and the control base 125 is connected to the magnetic component 123. The magnetic component 123 can realize a magnetic state and a demagnetization state under the action of the control base 125.

[0105] It is understandable that the magnetic state and demagnetization state of the magnetic element can be determined by adjusting the charged state of the control base 125 to determine the state of the magnetic element.

[0106] For example, when the adjustment handle 111 is adjusted to the open state, the control base 125 is charged and the magnetic part is in a magnetic state; when the adjustment handle 111 is adjusted to the closed state, the control base 125 is not charged and the magnetic part is in a demagnetized state.

[0107] In the embodiment of the present application, the magnetic base 100 further includes a handle portion, which is fixed to a side of the fixing platform 1210 away from the top wall 131 , and a gripping space is provided between the handle portion and the fixing platform 1210 to facilitate taking and placing the fixing base 120 .

[0108] In the embodiment of the present application, a mounting opening is provided on the bottom wall 132. Figure 6 As shown, the magnetic base 100 also includes a roller 160, and the axial direction of the roller 160 is perpendicular to the extension direction of the track 300. One end of the roller 160 is fixedly connected to a side wall 133 inside the installation port through a rotating shaft, and the other end is fixedly connected to the other side wall 133 inside the installation port through a rotating shaft, and the two side walls 133 are arranged opposite to each other. The roller 160 can be rotatably arranged relative to the bottom wall 132 through the rotating shaft, and at least part of the roller 160 is arranged to protrude from the bottom wall 132 to facilitate connection with the track 300. The magnetic base 100 can slide on the track 300 to change the position of the magnetic base 100, thereby changing the position of the robot body 200, adjusting the welding position, and improving the applicable environment of the robot.

[0109] It should be noted that the axial direction of the roller 160 can be parallel to the axial direction of the moving shaft 1120 , or can be perpendicular to the axial direction of the moving shaft 1120 , as long as the roller 160 can slide on the track 300 .

[0110] In addition, a portion of the roller 160 protrudes from the bottom wall 132 , and the portion protruding from the bottom wall 132 is connected to the track 300 .

[0111] It is worth mentioning that see Figure 6As shown, in order to improve the sliding stability of the magnetic base 100, two rollers 160 are provided on the base shell 130, which are arranged in the moving direction of the magnetic base 100 and have the same shape and structure.

[0112] In the examples of this application, see Fig.11 As shown, the magnetic base 100 also includes a driving assembly 170, which can adjust the tightness of the connection between the magnetic base 100 and the track 300, so as to facilitate the magnetic base 100 to be fixed on the track 300 and the magnetic base 100 to be removed from the track 300.

[0113] In the examples of this application, see Fig.11 As shown, the driving assembly 170 includes a rotating component 171 and a first swing arm component 172a and a second swing arm component 172b connected to the rotating component 171. The first swing arm component 172a and the second swing arm component 172b are respectively connected to opposite sides of the track 300, and the first swing arm component 172a and the second swing arm component 172b can swing toward each other or away from each other when the rotating component 171 rotates. When the first swing arm component 172a and the second swing arm component 172b swing toward each other, the squeezing force on the track 300 is gradually increased, so that the track 300 is clamped between the first swing arm component 172a and the second swing arm component 172b. When the first swing arm component 172a and the second swing arm component 172b swing toward the direction away from each other, the squeezing force on the track 300 is gradually reduced, so that the first swing arm component 172a and the second swing arm component 172b are gradually released from the track 300. Through this rotating component 171 and the first swing arm component 172a and the second swing arm component 172b connected to the rotating component 171, quick clamping and quick release can be achieved between the track 300, meeting the demand for quick disassembly between the magnetic base 100 and the track 300. In addition, this first swing arm component 172a and the second swing arm component 172b can also adapt to tracks 300 of different sizes by adjusting the distance between adjacent ones, thereby improving adaptability.

[0114] In the examples of this application, see Fig.11 As shown, the rotating component 171 includes a rotating handle 1710 and a rotating shaft 1711, and the axial direction of the rotating shaft 1711 is parallel to the axial direction of the moving shaft 1120. The rotating shaft 1711 is arranged in the accommodation space, and a connecting rod is arranged at least at one end of the rotating shaft 1711. The rotating handle 1710 is arranged outside the accommodation space, and the rotating handle 1710 is provided with a connecting hole. The rotating handle 1710 cooperates with the connecting rod on the rotating shaft 1711 through the connecting hole. When the rotating handle 1710 is rotated, the rotating shaft will be driven to rotate along the same rotation direction.

[0115] It should be noted that, in order to ensure that the rotating handle 1710 is connected to the connecting rod, a connecting hole is provided on the side wall 133, and the rotating handle 1710 passes through the connecting hole and is connected to the internal connecting rod.

[0116] In addition, in order to prevent damage between the rotating handle 1710 and the connecting rod, connecting rods are provided at opposite ends of the rotating shaft 1711, and connecting holes are provided on opposite side walls 133, so that the rotating handle 1710 can be connected to the connecting rods on both sides. The connecting rod on one side is a spare, and the connecting rod on the other side is a main one. When the main connecting rod is damaged, the rotating handle 1710 is removed and connected to the spare connecting rod to ensure use.

[0117] In the embodiment of the present application, the magnetic base 100 further includes a first supporting base and a second supporting base that are arranged opposite to each other. The first supporting base and the second supporting base are both fixed on the bottom wall 132 and are located in the accommodating space.

[0118] In the examples of this application, see Fig.11 As shown, the rotating shaft 1711 includes a rotating body 17110, a first thread segment 17111 and a second thread segment 17112. The rotating body 17110 is provided with the above-mentioned connecting rod, and the connecting rods at opposite ends of the rotating body 17110 pass through the first bearing base and the second bearing base respectively. There is a gap between the rotating body 17110 and the bottom wall 132 to ensure that the rotating body 17110 can rotate between the first bearing base and the second bearing base. The rotating body 17110 is also provided with the above-mentioned first thread segment 17111 and the second thread segment 17112, which are respectively arranged at opposite ends of the rotating body 17110 and located between the first bearing base and the second bearing base, and are spaced from each other, and the thread directions of the first thread segment 17111 and the second thread segment 17112 are opposite, so as to ensure that the first swing arm component 172a and the second swing arm component 172b swing toward each other or away from each other.

[0119] In the examples of this application, see Fig.11 As shown, the first swing arm component 172a and the second swing arm component 172b have the same structure. The first swing arm component 172a and the second swing arm component 172b both include a turbine 1720 and a swing arm 1721, the turbine 1720 is connected to the swing arm 1721, and the turbine 1720 of the first swing arm component 172a and the turbine 1720 on the second swing arm component 172b are respectively connected to the first thread segment 17111 and the second thread segment 17112.

[0120] When the rotating handle 1710 drives the rotating body 17110 to rotate, the turbine 1720 on the first swing arm component 172a and the turbine 1720 on the second swing arm component 172b swing in different directions respectively, so as to drive the swing arm 1721 of the first swing arm component 172a and the swing arm 1721 of the second swing arm component 172b to swing toward each other or away from each other respectively, so that the swing arm 1721 of the first swing arm component 172a and the swing arm 1721 of the second swing arm component 172b clamp the track 300 or separate the swing arm 1721 of the first swing arm component 172a and the swing arm 1721 of the second swing arm component 172b from the track 300. This further realizes the rapid fixing and rapid disassembly of the magnetic base 100 and the track 300.

[0121] It is worth mentioning that the maximum angle between the adjacent first swing arm components 172a and the second swing arm components 172b is 40° to 50° to ensure that the first swing arm components 172a and the second swing arm components 172b can be detached from the track 300. For example, it can be 43°.

[0122] In addition, the opening and closing angles of the first swing arm component 172a and the second swing arm component 172b can adapt to different tracks 300, thereby increasing the adaptability between the magnetic base 100 and different tracks 300 and improving the use environment of the robot.

[0123] See also Fig.12 As shown, in order to improve the mobility and stability of the magnetic base 100 on the track 300, the magnetic base 100 includes two groups of drive components 170. The two groups of drive components 170 adopt the same structure and are respectively arranged on opposite sides of the base shell 130. The two groups of drive components 170 are arranged in sequence in the extension direction of the track 300.

[0124] In the embodiment of the present application, the swing arm 1721 includes a second clamping portion. The turbine 1720 adopts a disc structure, and the turbine 1720 is arranged between the second clamping portion. The turbine 1720 is rotatably connected to the swing arm 1721 and the bottom wall 132 by a structure such as a screw or a bolt, so that the swing arm 1721 rotates with the turbine 1720 during the rotation process.

[0125] In the examples of this application, see Figure 6 As shown, the first swing arm component 172a and the second swing arm component 172b further include a connecting shaft 1722 and a second guide member 1723. The second guide member 1723 is connected to the swing arm 1721 through the connecting shaft 1722. The second guide member 1723 can be a guide triangular wheel. The guide triangular wheel can effectively avoid the rib plate above the track 300 and other unfavorable factors, so that the movement of the robot is not affected by other factors.

[0126] In the examples of this application, see Figure 6 As shown, the second guide member 1723 includes a first guide wheel 17230, a second guide wheel 17231 and a third guide wheel 17232 which are spaced apart from each other. The first guide wheel 17230, the second guide wheel 17231 and the third guide wheel 17232 are spaced apart from each other, and the angles formed between the first guide wheel 17230, the second guide wheel 17231 and the third guide wheel 17232 are equal, which are all 120°. Two of the first guide wheel 17230, the second guide wheel 17231 and the third guide wheel 17232 are connected to the track 300, and an avoidance space is formed between the adjacent guide wheels. When one of the guide wheels encounters an obstacle, the remaining guide wheels will rotate in a circle relative to the guide wheel to cross the obstacle, so that the magnetic base 100 can continue to move forward.

[0127] In the examples of this application, see Fig.11 As shown, the swing arm 1721 includes an adjustment knob 17210, a first swing portion 17211, and a second swing portion 17212. One end of the first swing portion 17211 is fixedly connected to the turbine 1720, and can swing along with the rotation of the turbine 1720; the other end of the first swing portion 17211 is rotationally connected to one end of the second swing portion 17212, and the other end of the second swing portion 17212 is fixedly connected to the connecting shaft 1722 in the second guide member 1723. The adjusting knob 17210 is arranged at the connection between the first swing part 17211 and the second swing part 17212. The adjusting knob 17210 can tighten and loosen the first swing part 17211 and the second swing part 17212. When the first swing part 17211 and the second swing part 17212 are loosened, the second swing part 17212 can rotate relative to the first swing part 17211 to fold the second swing part 17212 and the first swing part 17211, so that when the magnetic base 100 moves to the cross-intersection structure of the track 300, the second swing part 17212 and the first swing part 17211 are folded to avoid the cross-intersection structure in the track 300, thereby ensuring the guiding property of the magnetic base 100.

[0128] In the examples of this application, see Fig.11 As shown, the first swinging portion 17211 includes a third clamping portion, and the second swinging portion 17212 includes an inserting portion, which is inserted into the third clamping portion and is rotatably fixed in the third clamping portion by a rotating shaft or other structure.

[0129] It should be noted that the second swing portion 17212 can be folded up and down relative to the first swing portion 17211, and can also be folded only upward or only downward.

[0130] In the embodiment of the present application, the first swinging portion 17211 further includes a first limiting portion, which is disposed at the bottom of the first swinging portion 17211 and has a table-like structure. The second swinging portion 17212 further includes a second limiting portion, which is also disposed at the bottom of the second swinging portion 17212 and also has a table-like structure. The first limiting portion and the second limiting portion cooperate with each other and abut against each other. Through the first limiting portion and the second limiting portion, the second swinging portion 17212 can only be folded upward relative to the first swinging portion 17211.

[0131] In the examples of this application, see Fig.12 As shown, the first swing arm component 172a and the second swing arm component 172b also include a plurality of universal wheels 1724, which are arranged on the side of the swing arm 1721 close to the track 300. The universal wheels 1724 can improve the smoothness of movement of the magnetic base 100 on the track 300.

[0132] Working process: fix the robot body 200 on the fixed platform 1210 in advance by bolts, screws and other structures; fix the magnetic base 100 with the robot body 200 fixed on the track 300, rotate the rotating handle 1710, so that the first swing arm component 172a and the second swing arm component 172b on the front and rear sides of the base shell 130 gradually swing toward each other, so that the first swing arm component 172a and the second swing arm component 172b are closed, and the track 300 is clamped between the first swing arm component 172a and the second swing arm component 172b. Push the magnetic base 100 to move it along the extension direction of the track 300. When it moves to the appropriate position, control the adjustment handle 111 to swing in a circle, and the rolling part 1131 gradually slides from the plane 1221 on the sliding position 1220 to the inclined surface 1222. The sliding block 122 gradually moves to the side close to the moving body 1130, and the height of the sliding block 122 decreases. The height of the fixed body 121 decreases with the movement of the sliding block 122, and the fixed seat 120 descends, and the magnetic member 123 is connected to the track 300. At this time, adjust the state of the magnetic member 123 from the demagnetized state to the magnetic state, so that the magnetic member 123 and the track 300 are magnetically attracted, and the magnetic base 100 is fixed on the track 300, and relative sliding is not easy to occur. When it is necessary to move, adjust the state of the magnetic member 123 from the magnetic state to the demagnetized state, so that the magnetic member 123 is connected to the track 300, and can slide on the track 300. The control adjustment handle 111 is controlled to swing in a circle, the rolling part 1131 gradually moves from the inclined surface 1222 on the sliding position 1220 to the plane 1221, the sliding block 122 gradually moves to the side away from the moving body 1130, the height of the sliding block 122 increases, the height of the fixed body 121 increases with the movement of the sliding block 122, the fixed seat 120 increases, the magnetic member 123 gradually moves away from the track 300, and the magnetic member 123 is suspended on the track 300, at this time, the magnetic base 100 can be pushed to move on the track 300. The triangular guide wheel in the second guide member 1723 can cross obstacles, and improve the sliding smoothness of the magnetic base 100 on the track 300. When encountering a cross-section of the track 300 , the first swing part 17211 and the second swing part 17212 can be loosened by adjusting the knob 17210 to fold the second swing part 17212 relative to the first swing part 17211 , thereby avoiding the cross-section track 300 .

[0135] In the embodiment of the present application, the robot includes a robot body 200 and a magnetic base 100 as described in any one of the first embodiments, and the robot body 200 is fixed to a fixed platform 1210 of a fixed body 121 by a fixing structure such as bolts or screws. The fixed body 121 is connected to a track 300 on a side away from the robot body 200. The track 300 can be an I-beam structure. The magnetic member 123 on the fixed body 121 can be magnetically adsorbed on the top of the track 300, and the second guide member 1723 on the magnetic base 100 is arranged on the side of the track 300, so as to fix the magnetic base 100 on the track 300.

[0136] Through the adjustment assembly 110 and the fixing seat 120 on the magnetic base 100, the magnetic base 100 can be quickly connected to the track 300 and quickly removed from the track 300. Through the roller 160 and the plurality of universal wheels 1724 on the magnetic base 100, the convenience of moving the magnetic base 100 on the track 300 is improved.
