In view of this, the present application proposes a whole vehicle assembly system, which includes a frame turning device, and all whole vehicle assembly systems including the frame turning device belong to the whole vehicle assembly system described in the present application. Fig. 1 to 3 are schematic structural views of an embodiment of a frame overturning device provided in the present application.

Referring to fig. 1 to 3, according to a first aspect of the present application, a frame turning device is provided, and the frame turning device includes a main body rack 1 and a transporting device 2. The main body rack 1 includes a carrying rack 11, a driving device 12 provided on the carrying rack 11, and a mounting rack 13 connected to the driving device 12. The driving device 12 is used for driving the mounting rack 13 to turn around the axis in the first direction M; the mounting rack 13 is provided with a magnetic attraction portion 14 for magnetically attracting the stationary frame 100. The transporting device 2 is disposed corresponding to the mounting rack 13, and the transporting device 2 is configured to be able to receive and transport the vehicle frame 100 when the mounting rack 13 is turned over.

In the present application, the first direction M is a relative direction, and the first direction M may be set as an extending direction of the rotation axis of the mounting stage 13.

In the technical scheme of the application, the frame turnover device installs the frame 100 through the installation rack 13 and magnetically attracts the fixed frame 100 through the magnetic attraction part 14 on the installation rack 13. After the frame 100 is fixed, the driving device 12 drives the mounting rack 13 to drive the frame 100 to rotate together, so that the frame 100 is turned over. When the carriage 100 is turned over, the transport device 2 receives and transports the carriage 100 to other stations, thereby facilitating subsequent assembly of the carriage 100 by an operator. In this application, the frame turning device magnetically attracts the fixed frame 100 by setting up the magnetic attraction part 14 on the mounting rack 13, so in the turning process, the stability of the frame 100 is better, and the magnetic attraction part 14 does not need to correspond to the structural setting of the frame 100, so the universality is also higher.

In some embodiments, the main body stage 1 includes two carrying stages 11 disposed at opposite intervals in the first direction M, and the mounting stage 13 is rotatably mounted between the two carrying stages 11. The two carrying carriages 11 are telescopically arranged in the second direction N to adjust the height of the mounting carriage 13 in the second direction N. Wherein the first direction M and the second direction N are perpendicular to each other.

In the present application, the second direction N is a relative direction, and when the first direction M is a horizontal direction, the second direction N may be set to be an up-down direction, and when the first direction M is other directions, the second direction N may be correspondingly adjusted.

The two carrying platforms 11 are oppositely arranged along the first direction M, and two ends of the mounting platform 13 are respectively connected with the two carrying platforms 11, which makes the mounting platform 13 relatively stable in rotation. And the two carrying carriages 11 can be telescopically arranged in the second direction N so as to adjust the position of the mounting carriage 13 in the second direction N. When the mounting rack 13 rotates around the axis in the horizontal direction, the two carrying racks 11 can be telescopically arranged in the up-down direction, so that the height of the mounting rack 13 is adjusted, and the mounting rack 13 can be adjustably arranged in other directions. The position of the mounting rack 13 is adjustable, so that the frame 100 is more convenient to mount, and the mounting rack 13 can meet more use conditions.

Referring to fig. 1 to 3, in some embodiments, the mounting rack 13 includes at least two main body rods 131 and a connecting rod 132 connecting the at least two main body rods 131 to each other, and the at least two main body rods 131 are disposed along the first direction M in an opposite and spaced manner along the third direction Y. At least one magnetic attraction part 14 is arranged on at least one main body rod 131. The first direction M is disposed at an angle to the third direction Y.

The mounting rack 13 forms a mounting frame with the connecting rods 132 through the plurality of main body rods 131, which makes the stress more uniform and the mounting more stable when the frame 100 is mounted on the mounting rack 13. The plurality of main body rods 131 are arranged at intervals along the third direction Y, so that a plurality of hollow parts exist on the mounting rack 13, and the plurality of hollow parts can avoid the protruding structure on the frame 100 when the frame 100 is mounted, so that the frame 100 and the mounting rack 13 are more compact. It should be noted that, in the present embodiment, the area occupied by the plurality of hollowed portions on the mounting rack 13 is relatively large, which makes other portions difficult to interfere with the frame 100, so that the mounting rack 13 does not need to adjust its own structure corresponding to the structure of the frame 100.

In some embodiments, the magnetic attraction portion 14 includes a plurality of electromagnets, and each main body rod 131 is provided with a plurality of electromagnets at intervals. The frame overturning device further comprises a power supply which is electrically connected with the electromagnets respectively.

The magnetic attraction portion 14 generates magnetic force by a plurality of electromagnets in cooperation with a power source, thereby attracting and fixing the vehicle frame 100. The electromagnet generates magnetic force when electrified and disappears when powered off, which makes the installation and disassembly of the frame 100 more convenient and also cleans the electromagnet better when foreign matters are adsorbed on the electromagnet. A plurality of electromagnets are arranged on each main body rod 131 at intervals, so that the frame 100 is stressed uniformly during installation.

Of course, other embodiments of the magnetic attraction portion 14 are also provided, for example, the magnetic attraction portion 14 may be configured as a single large magnet, so that the magnetic attraction force is more concentrated and stable, and the magnetic attraction portion 14 may also use a permanent magnet to magnetically attract the fixed frame 100.

Referring to fig. 1 to 3, in some embodiments, the frame flipping device further includes a controller and a gravity sensor mounted on the mounting rack 13, wherein the gravity sensor is used for sensing the weight of the frame 100 mounted on the mounting rack 13. The controller is electrically connected with the gravity sensor and the power supply respectively, and the controller is used for controlling the output of the power supply according to the weight of the vehicle frame 100 sensed by the gravity sensor.

The magnetic attraction force of the electromagnet is related to the output of the power supply, and when the output of the power supply is larger, the magnetic attraction force of the electromagnet is larger. Therefore, in the present embodiment, the weight of the frame 100 mounted on the mounting rack 13 is sensed by the gravity sensor, and then the controller is used to control the output of the power supply according to the weight of the frame 100 sensed by the gravity sensor, so as to ensure that the magnetic attraction force of the electromagnet can adsorb and fix the currently mounted frame 100, and reduce unnecessary power waste.

In some embodiments, the transporting device 2 includes a receiving plate 21 and a plurality of support columns 22 disposed at intervals at the bottom of the receiving plate 21, wherein one end of each support column 22 is connected to the bottom of the receiving plate 21, and the other end is provided with a roller 23.

In practical use, some components are required to be mounted on the back of the frame 100 and others are required to be mounted on the front of the frame 100 during assembly of the vehicle body, so that the frame 100 needs to be turned by the frame turning device. When the carriage 100 is completely flipped, the carriage 100 generally needs to be transported to the next station for assembly. In this embodiment, therefore, one end of the supporting columns 22 of the transporting device 2 is connected to the bottom of the receiving plate 21, and the other end is provided with rollers 23. When the magnetic part 14 is not attached to the frame 100, the frame 100 is placed on the receiving plate 21, and the plurality of supporting columns 22 transport the receiving plate 21 and the frame 100 on the receiving plate 21 to the next station through the rollers 23, so as to perform the subsequent assembly.

Referring to fig. 1 to 3, in some embodiments, a mounting plate is disposed at the top of each roller 23, each support column 22 includes a cylinder 221 mounted on the corresponding mounting plate and a telescopic rod 222 extending from the cylinder 221 toward the receiving plate 21, and the telescopic rod 222 is connected to the bottom of the receiving plate 21.

After the carriage 100 is placed on the receiving plate 21, the transporting device 2 needs to continue transporting the carriage 100. While if the transporting device 2 is directly far from the main body rack 1, part of the structure on the frame 100 may interfere with the main body rack 1, so in this embodiment, each support column 22 includes a cylinder 221 mounted on the corresponding mounting plate and a telescopic extension extending from the cylinder 221 toward the receiving plate 21.

When the frame 100 is placed on the receiving plate 21, each telescopic rod 222 is extended toward the body stage 1 so that the receiving plate 21 approaches and contacts the frame 100. Then, the magnetic attraction portion 14 will cancel the adsorption and fixation of the frame 100, the frame 100 is placed on the bearing plate 21 along the trend, and the air cylinder 221 on each support column 22 drives the corresponding telescopic rod 222 to retract towards the direction away from the main body rack 1, so that the frame 100 and the main body rack 1 cancel contact, and the transportation device 2 prevents the frame 100 from interfering with the main body rack 1 during the subsequent transportation of the frame 100.

Referring to fig. 1 to 3, in some embodiments, the transporting device 2 further includes a plurality of springs corresponding to the support columns 22 one by one, and each spring is sleeved on a corresponding telescopic rod 222. The actual weight of the frame 100 is large, so that the transportation device 2 may need a certain buffering when the frame 100 is transferred from the main gantry 1 to the transportation device 2, thereby preventing damage. In this embodiment, the transporting device 2 includes a plurality of springs, and each spring is sleeved on the corresponding telescopic rod 222, so that each supporting column 22 obtains a certain buffer.

In some embodiments, the transporting device 2 further includes a plurality of protection plates 24 corresponding to the rollers 23 one by one, and each protection plate 24 includes a plurality of protection plates 24 respectively disposed on the peripheral sides of the corresponding rollers 23. In a specific application, the rollers 23 may collide with sundries in the workshop when the transporting device 2 is moving, and this may affect the transportation of the frame 100. In this embodiment, therefore, the transporting device 2 further includes a plurality of shielding plates 24 respectively provided on the peripheral sides of the corresponding rollers 23, thereby protecting the rollers 23 from impact.

According to a second aspect of the present application, a whole vehicle assembly system is provided, in which different components are required to be mounted on a vehicle frame during assembly of the whole vehicle, but in the assembly process, a part of the components are required to be mounted on one side of the vehicle frame, and another part of the components are required to be mounted on the other side of the vehicle frame, so that the vehicle frame needs to be turned over. Therefore, the whole vehicle assembly system is provided with the frame overturning device according to any embodiment, so that the frame can be overturned.

In practical application, another lifting and transporting device in the whole vehicle assembly system transports the frame to the mounting rack 13, and then the magnetic attraction part 14 on the mounting rack 13 can magnetically attract and fix the frame 100. The driving device 12 on the carrying rack 11 drives the mounting rack to rotate at this time, and the mounting rack 13 drives the frame 100 to turn around the axis in the first direction M. The transporting device 2 may be disposed below the mounting rack 13 in actual use, and when the frame 100 is turned over, the cylinder 221 forming the support column 22 drives the telescopic rod 222 to extend outwards toward the mounting rack 13, so as to contact with the frame 100. At this time, the magnetic attraction portion 14 cancels the attraction fixation of the carriage 100, so that the carriage 100 is placed on the receiving plate 21. Thereafter, the air cylinder 221 drives the telescopic rod 222 to retract so that the carriage 100 is separated from the mounting rack 13, and the transporting device 2 thereafter transports the carriage 100 to the next station.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples merely represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
