After a predetermined time, it is considered that the new roof box 302 has completely fallen onto the flipping arm 222, and the old roof box 303 of the previous vehicle has been completely pushed between the two conveyor belts 1132 of the second transmission assembly 112 due to the limitation of the width of the accommodating space, the second electromagnet is energized to generate attractive force with the second magnet, so that the new roof box 302 is fixed on the flipping arm 222, and then the flipping motor 221 flips 180 ° to move the flipping arm 222 from the first position to the second position.
The present embodiment may further realize that when the roof box on the turning arm 222 is determined to be the new roof box 302 by setting the position where the RFID tag is attached and the position of the RFID reader, it is indicated that the old roof box 303 has been pushed between the two conveyor belts 1132 of the second transmission assembly 112 for storage, for example, when the RFID tag is attached to the roof box top and is close to the position of the second transmission assembly 112, due to the limitation of the width of the accommodating space, when the controller confirms that the current roof box is the new roof box 302 according to the signal received by the RFID reader, the old roof box 303 basically completely enters between the two conveyor belts of the second transmission assembly 112 for storage.
A platform assembly 21 is connected to the support 12 for removing and mounting replacement parts thereon during movement of the movement means through the movement space. Specifically, the platform assembly 21 includes a platform 211 capable of rotating and lifting relative to the support 12, two parallel guide rails 212 disposed below the platform 211 and connected to the platform 211, and a sled 213; the trolley 213 is movable relative to the track platform 2 in the direction of movement of the movement means, and the lower end thereof is capable of adsorbing the replacement parts gradually released from the transport assembly 22 and placing the replacement parts adsorbed thereto on the movement means moving to the lower side thereof. Specifically, during the replacement process, the old roof box 303 on the moving device moves between the two guide rails 212 along with the movement of the vehicle, the pulley 213 is slidably disposed between the two guide rails 212, and a first electromagnet capable of generating an attractive force with the first magnet is disposed on the lower end surface of the pulley.
The platform 211 includes a lateral platform 2111, a longitudinal platform 2112, and a lifting unit 2113, which can be lifted up and down with respect to the stand 12. The longitudinal platforms 2112 are clamped between the lateral platforms 2111 and can rotate and move relative to the lateral platforms 2111, the guide rail 212 is connected to the longitudinal platforms 2112, and the guide rail 212 is provided with a sliding groove matched with the sliding table 3012 on the guide frame 301 along the length direction of the guide rail 212, so that the roof box can slide along the length direction of the guide rail 212. Preferably, the two guide rails 212 form diverging openings at both ends in the length direction thereof, and the smaller the portion of the two guide rails 212 forming the diverging openings is located closer to the center of the guide rails 212, the smaller the minimum distance between the two guide rails 212 is.
In order to ensure that the sled 213 does not block the movement of the new roof box 302, it is required that the height of the lower end surface of the second electromagnet is equal to the height of the lower end surface of the first electromagnet after the flipping arm 222 is located at the second position. Moreover, in order to avoid that the new roof box 302 has been separated from the turning arm 222, and the trolley 213 has not sucked the new roof box 302, when the turning arm 222 is required to be in the second position, the turning arm 222 is arranged parallel to the trolley 213, and the distance between the center of the lower end surface of the first electromagnet and the center of the lower end surface of the second electromagnet is equal to the length of the roof box, specifically, the distance between the center of the lower end surface of the first electromagnet and the center of the lower end surface of the second electromagnet can be determined according to the length of the roof box of the current vehicle, so that the second electromagnet and the first electromagnet are prevented from being far away from the first magnet on the roof to slide down the new roof box 302. In order to ensure the force balance, in this embodiment, the first electromagnet is disposed at the center of the lower end surface of the pulley 213, and the second electromagnet is disposed at the center of the lower end surface of the flip arm 222 when it is in the second position.
Requiring the flip arm 222 to be just or already in the second position before the old roof box 303 on the current vehicle can contact the new roof box 302 on the flip arm 222 can be determined by the distance between the vehicle and the flip arm 222 when the vehicle type can be identified by the vehicle movement speed and body information identifying means; also requiring that the first electromagnet on sled 213 is already in an energized state before the old roof box 303 on the current vehicle contacts the new roof box 302, the first electromagnet can be controlled to energize while the flip arm 222 is moved to the second position.

Preferably, four notches 21113 are provided, and the four notches 21113 are uniformly distributed along the circumferential direction of the lateral platform 2111.
A plurality of second elastic buffer units 2114 are arranged between the longitudinal platform 2112 and the transverse platform 2111, and a plurality of corner parts are arranged on the longitudinal platform 2112; the second elastic buffer unit 2114 includes a third magnetic attraction member 21141 provided at each corner portion, and a plurality of fourth magnetic attraction members 21142, and the plurality of fourth magnetic attraction members 21142 are provided on the lateral platform 2111 and around the third magnetic attraction member 21141; a repulsive force is generated between each of the third magnetic attraction members 21141 and the fourth magnetic attraction members 21142 provided around the third magnetic attraction member 21141, and the longitudinal lands 2112 can be kept in a balanced state by the repulsive force and their own weight.
In this embodiment, the third magnetic attraction member 21141 and the fourth magnetic attraction member 21142 are both magnets, or alternatively, electromagnets. Four third magnetic adsorption members 21141 are circumferentially distributed on the upper surface of the inner wall of the notch 21113 and denoted as a first magnet 21141a, the lower surface of the inner wall of the notch 21113 is provided with the third magnetic adsorption members 21141 which are arranged in one-to-one correspondence with the third magnetic adsorption members 21141 arranged on the upper surface of the inner wall of the notch 21113 and denoted as a second magnet 21141b, and each corner is provided with the third magnetic adsorption member 21141 and denoted as a third magnet.
Third magnetic attraction member 21141 and fourth magnetic attraction member 21142 form the distribution of fig. 5, one N, S distribution is shown in fig. 5, and the polarity of all magnetic attraction members in fig. 5 can be interchanged. The third magnetic attraction member 21141 is disposed through a corner portion, specifically, four first magnets 21141a and four second magnets 21141b form a cube, and four first magnets 21141a and four second magnets 21141b are respectively vertices of the cuboid, and the third magnet is disposed at a center position of the cuboid; and the third magnet generates a repulsive force with the first four magnets 21141a located above the third magnet and generates a repulsive force with the second four magnets 21141b located below the third magnet, so that the longitudinal platform 2112 can be stationary relative to the transverse platform 2111 under the action of the repulsive force and gravity.
Of course, the number of the third magnetic attraction members 21141 may be two, and one corner portion may be disposed on the opposite side to the upper surface of the inner wall of the notch 21113, and one corner portion may be disposed on the opposite side to the lower surface of the inner wall of the notch 21113, so that the following conditions may be satisfied: the longitudinal platform 2112 can be stationary relative to the lateral platform 2111 under the repulsive force and its own weight as described above.
The longitudinal platform 2112 remains balanced under the influence of several repulsive forces with the lateral platform 2111 and its own weight. As shown in fig. 1, due to the partial deviation that may occur when the guide frame 301 enters between the two guide rails 212 as the vehicle moves, the guide frame 301 will give a force to the two guide rails 212, so that the longitudinal platform 2112 deflects by a certain angle against the repulsive force as the guide rails 212 are under the force given by the guide frame 301, at this time, the magnitude of each repulsive force will change, so that the resultant force of the repulsive forces between the longitudinal platform 2112 and the lateral platform 2111 is a force that reverses the longitudinal platform 2112. After the roof box replacement is completed, the vehicle exits between the two rails 212 and the longitudinal platform 2112 will return to its original position under the force of the resultant force.
Moreover, since it is impossible for the driver to make 100% of the vehicle travel in a straight line during the replacement of the roof box, that is, there is little reciprocating deflection, the guide rail 212 has an elastic buffering effect by the above-mentioned second elastic buffering unit 2114, that is, the guide rail 212 deflects along with the movement of the roof box, so that the platform assembly 21 deflects along with it, thereby aligning the new roof box 302 with the old roof box 303, so that the deflection of the vehicle to some extent does not affect the replacement of the roof box, and the collision between the old roof box 303 and the guide rail 212 can be buffered by the second elastic buffering unit 2114, thereby avoiding the occurrence of strong collision.
As shown in fig. 4, the turnover motor 221 is fixed on the longitudinal platform 2112, specifically, two motor mounting frames 21121 are disposed at one end of the longitudinal platform 2112 along the length direction thereof, that is, the length direction of the guide rail 212, each motor mounting frame 21121 is fixed with one turnover motor 221, the turnover arm 222 is disposed between the two motor mounting frames 21121, the extending ends of the two turnover motors 221 are respectively connected to the turnover arm 222 through a coupling 223, the central axis of the extending end of the turnover motor 221 is perpendicular to the length direction of the guide rail 212, and the rotation of the turnover arm 222 around the central axis of the extending end of the turnover motor 221 is realized through the synchronous action of the two turnover motors 221.
As shown in fig. 6, in this embodiment, two lifting units 2113 are provided, each lifting unit 2113 includes a plurality of rack and pinion structures 21132 circumferentially arranged, racks of each rack and pinion structure 21132 are connected with support columns, and one end of each support column penetrates through the transverse platform 2111 and can move up and down synchronously relative to the transverse platform 2111.
Specifically, the lifting unit 2113 includes a lifting mounting frame 21131, a rack and pinion structure 21132, a lifting motor 21133, and a guide wheel 21134, one end of the lifting mounting frame 21131 is fixed on the step 3, and the lifting motor 21133 is fixed thereon; the rack and pinion structures 21132 are provided with two symmetrical arrangement, each rack and pinion structure 21132 comprises a driving gear 21132a, a driven gear 21132c meshed with the driving gear 21132a, a first rack 21132b meshed with the driving gear 21132a and a second rack 21132d meshed with the driven gear 21132c respectively, an output end of the lifting motor 21133 is connected with the driving gear 21132a, and the driving gear 21132a and the driven gear 21132c are both rotatably connected with the lifting mounting frame 21131.

The other side of the large diameter end of each step support column 21135 is provided with a plurality of pairs of guide wheels 21134 rotatably connected to the lifting mounting frame 21131, and the other side of the large diameter end of each step support column 21135 is in contact with the corresponding plurality of pairs of guide wheels 21134, so that the guide wheels 21134 play a role in guiding and stabilizing when the rack moves up and down.
As shown in fig. 6 and 7, a first elastic buffer unit 2115 is disposed between the lateral platform 2111 and each support column, and the first elastic buffer unit 2115 includes a first magnetic adsorption member 21151 disposed in one-to-one correspondence with the support columns and disposed at one end of each support column penetrating through the lateral platform 2111, and a plurality of second magnetic adsorption members 21152 disposed on the lateral platform 2111 and surrounding the first magnetic adsorption member 21151; a repulsive force is generated between each of the first magnetic attraction members 21151 and the second magnetic attraction members 21152 provided around the first magnetic attraction member 21151, and the lateral platform 2111 can be kept in a balanced state by the repulsive force and its own weight.
Specifically, the first magnetic attraction member 21151 and the second magnetic attraction member 21152 are both magnets, and an electromagnet may be selected. Referring to fig. 4, 6 and 7, a plurality of third installation portions 21111b are provided on the longitudinal platform 2112 along the circumferential direction thereof, the third installation portions 21111b are provided in one-to-one correspondence with the step support columns 21135, four corresponding third installation portions 21111b are provided, and each third installation portion 21111b is provided with a through hole 21111c for passing through the small diameter end of each step support column 21135, and a plurality of first installation holes 21111d provided around the through hole 21111 c. Preferably, in this embodiment, four first mounting holes 21111d are provided, and two second magnetic attraction members 21152 distributed along the axial direction of each first mounting hole 21111d are respectively denoted by a magnet four 21151a and a magnet five 21151b.
The small diameter end of each step support column 21135 is provided with a second mounting hole 21135a, and a second magnetic attraction member 21152 is provided in the second mounting hole 21135a, which is denoted as magnet six.
Four magnets four 21151a and four magnets five 21151b are mounted in four first mounting holes 21111d of each third mounting portion 21111b, and one magnet six is mounted in a second mounting hole 21135a of the small-diameter section of the step support column 21135 corresponding to the third mounting portion 21111 b. The four magnets four 21151a and four magnets five 21151b form a cuboid structure as shown in fig. 7, a N, S distribution is shown in fig. 7, and polarities of all the magnetically attractable components in fig. 7 can be interchanged. The magnet six is located at the center of the cuboid structure, and the magnet six is mutually repelled with the corresponding four magnets four 21151a and four magnets five 21151b respectively, so that a repulsive force is formed, and the transverse platform 2111 can be stationary relative to the lifting unit 2113 under the action of the repulsive force and self gravity.
The first elastic buffer unit 2115 and the second elastic buffer unit 2114 mentioned above are not limited to the above-mentioned structure, and other structures such as a spring array or a rubber block may be adopted, and it is only necessary that the transverse platform 2111 can be lifted and lowered relative to the lifting unit 2113 by the first elastic buffer unit 2115, and the transverse platform 2111 can be lifted and lowered and rotated relative to the longitudinal platform 2112 by the second elastic buffer unit 2114.
In order to secure the stability of the lateral platform 2111, the lift motors 21133 of the two lift units 2113 are required to operate synchronously so that the lateral platform 2111 can maintain a horizontal equilibrium state without deflection, and even if deflection occurs, the horizontal equilibrium state is restored under the action of the repulsive force.
The step support column 21135 in this embodiment has another function, specifically, the step support column 21135 in this embodiment is configured to prevent the electromagnet or magnet forming the first elastic buffer unit 2115 from failing to drop the lateral platform 2111, and the large diameter end of the step support column 21135 is disposed below the small diameter end thereof, so that the lateral platform 2111 is supported by the step surface formed by the large diameter end and the small diameter end of the step support column 21135 when the electromagnet or magnet forming the first elastic buffer unit 2115 fails, thereby playing a protective role.
In addition, the four stepped support columns 21135 and the longitudinal platform 2112 form the above-described movement space, providing space for the vehicle to travel when the roof box is replaced.
Because the small diameter section of each step support column 21135 is extended into the corresponding second mounting hole 21135a, the height of the transverse platform 2111 can be matched with the height of the guide frame 301 of the current vehicle in the working process by limiting the length of the small diameter section of each step support column 21135, and the problem that the transverse platform 2111 is separated from the small diameter section of the step support column 21135 can be avoided.
The lateral platform 2111 remains balanced under the influence of several repulsive forces with the stepped support posts 21135 and its own weight. Since the heights of different vehicles are different, in order to ensure that the height of the platform 211 can be adjusted according to the heights of different vehicles, so as to ensure that the guide frame 301 of the vehicle can enter between the two guide rails 212, when the vehicle model is identified by the vehicle body information identification device, the height between the platform 211 and the ground needs to be adjusted according to the vehicle model, so that the guide frame 301 of the vehicle, of which the roof box needs to be replaced, can enter between the two guide rails 212. Moreover, since the road surface on which the vehicle is traveling cannot be completely leveled, the height of the lateral platform 2111 can be timely adjusted according to the road surface leveling degree through the first elastic buffer unit 2115, so as to avoid damaging the new roof box 302 and affecting the vehicle running.
When the height of the lateral platform 2111 is adjusted, the height of the longitudinal platform 2112 will be restored to the equilibrium state by the second elastic buffer unit 2114, so that the relative positional relationship between the lateral platform 2111 and the longitudinal platform 2112 is unchanged when the platform 211 is in the equilibrium state.
Taking the replacement of a roof box as an example, referring to the replacement process shown in fig. 8 to 12, a specific process of replacing a roof box for a vehicle using the above-described apparatus for automatically replacing components is as follows:
After the controller confirms the roof box corresponding to the current vehicle according to the license plate number, the new roof box 302 of the corresponding model is placed between the two conveyor belts 1132 of the first transmission assembly 111, and simultaneously, the first electromagnet and the fixed electromagnet on the pulley 213 are controlled to work, so that the old roof box 303 is fixed on the guide frame 301 through the attractive force between the fixed electromagnet and the second magnet, and simultaneously, the height of the transverse platform 2111 to be matched with the current vehicle is adjusted according to the model of the vehicle through the lifting unit 2113, and the platform 211 is restored to the equilibrium state before the old roof box 303 on the current vehicle enters the two guide rails 212.
Along with the running of the vehicle, a driver controls the running direction and the running speed of the vehicle to enable the old roof box 303 of the current vehicle to enter between the two guide rails 212, and enables the sliding table 3012 on the old roof box 303 to be matched with the guide rails 212, so that the guide rails 212 deflect along with the old roof box 303 when the old roof box 303 deflects, and the roof box is ensured to be replaced. Continued travel of the vehicle brings the old roof box 303 into contact with the new roof box 302, and since the new roof box 302 is prevented from falling off the invert arm 222 by controlling the magnitude of the current of the second electromagnet on the invert arm 222 while the magnitude of the force that moves the new roof box 302 relative to the invert arm 222 along the length of the guide rail 212 is smaller than the magnitude of the force that moves the old roof box 303 relative to the guide frame 301 along the length of the guide rail 212, the repulsive force between the second auxiliary magnet at the rear of the new roof box 302 and the first auxiliary magnet at the front of the old roof box 303, and the continued travel power of the vehicle cause the old roof box 303 to push the new roof box 302 gradually off the invert arm 222 and move along the length of the guide rail 212 on the side of the sled 213.
Since the minimum distance between the flip arm 222 and the sled 213 is less than the length of the roof box, a portion of the new roof box 302 is already located in the lower portion of the sled 213 before the new roof box 302 is disengaged from the flip arm 222; because the first electromagnet is in the electrified state, attractive force exists between the first electromagnet and the first magnet on the new roof box 302, and the new roof box 302 can continue to move towards the pulley 213; meanwhile, as the distance between the first electromagnet and the first magnet decreases, the attractive force gradually increases, and when the attractive force increases to a certain extent, the trolley 213 can move towards the new roof box 302 against the friction force between the trolley 213 and the guide rail 212, so that the time for the new roof box 302 to move from the position right under the turnover arm 222 to the position right under the trolley 213 is shortened.
When the new roof box 302 moves to the position right below the trolley 213, that is, when the first electromagnet and the first magnet are in a state of being arranged right opposite to each other, the new roof box 302 is fixed at the bottom of the trolley 213; at this time, the old roof box 303 moves to a position right below the tilting arm 222, that is, the second electromagnet is in a state of being disposed opposite to the first electromagnet. In the process that the new roof box 302 moves from the position right under the turnover arm 222 to the position right under the pulley 213, the attractive force between the first electromagnet and the first magnet and the attractive force between the second electromagnet and the first magnet are made to be larger than the gravity of the pulley 213 by controlling the currents of the first electromagnet and the second electromagnet, so that the new roof box 302 cannot fall in the process that the new roof box moves from the position right under the turnover arm 222 to the position right under the pulley 213.
When the old roof box 303 is confirmed to move to the position right below the turning arm 222 by the RFID tag and the RFID reader, the driver cuts off the power of the fixed magnet, the old roof box 303 is fixed by the second electromagnet on the turning arm 222, and meanwhile, the new roof box 302 keeps in a contact state, but the new roof box 302 and the pulley 213 continue to run, and gradually decelerate under the action of friction force between the pulley 213 and the guide rail 212 until the movement is stopped; as the current vehicle continues to travel toward sled 213, old roof box 303 will gradually disengage from the current vehicle and new roof box 302 will gradually slide into guide frame 301; to ensure that the new roof box 302 can slide into the guide rail 301, it is required that the friction between the sled 213 with the new roof box 302 and the guide rail 212 is greater than the friction between the new roof box 302 and the guide rail 301.
Confirm that the new roof box 302 has been completely mounted on the guide frame 301 of the current vehicle through the RFID tag and the RFID reader; the fixed electromagnet is then controlled to energize so that the new roof box 302 is fixed to the guide frame 301, and the friction between the new roof box 302 and the guide frame 301 is required to be greater than the friction between the new roof box 302 and the trolley 213 and greater than the friction between the trolley 213 and the guide rail 212. The friction between the new roof box 302 and the guide rail 301 can be ensured to be greater than the friction between the trolley 213 and the guide rail 212 by controlling the current level of the first electromagnet on the trolley 213 or setting a limit structure that limits the operation of the trolley 213 or controlling the current level of the fixed electromagnet. Then, as the vehicle continues to run, the vehicle will deviate from the device for automatically replacing components described in this embodiment, so as to replace the roof box of the current vehicle.
After the old roof box 303 is fixed by the second electromagnet on the flipping arm 222, after waiting for a specified time, the flipping motor 221 is controlled to flip 180 °, and after the flipping arm 222 reaches the first position, the second electromagnet provided on the flipping arm 222 is controlled to be powered off, and waiting for the arrival of the next vehicle, after the arrival of the next vehicle is detected, the above-mentioned matching of the new roof box 302 is performed, the new roof box 302 is conveyed to the accommodation space through the first transmission assembly 111 and pushed to the second transmission assembly 112 with respect to the roof box 303, and then the roof box is replaced through the above-mentioned roof box replacement process.
According to the device for automatically replacing the parts, the roof box can be replaced under the condition that a vehicle is not suspended, and replacement cost is greatly reduced; and the roof box can be continuously replaced in a short time, so that the replacement efficiency is greatly improved.
