Description

Technical Field

[0001] The present invention relates to the technical field of automotive side panel transportation, and more specifically, to an automatic switching mechanism and a multi-model universal transportation device. Background Art

[0002] In the automotive structure, the side panel is one of the main parts. In the automotive welding workshop, the side panel is produced by the side panel automatic line. After production, it needs to be transported to the general assembly station for vehicle assembly welding through a conveyor line + side panel hanger. Due to the flexible production requirements of the production line, usually one production line needs to be compatible with the production of multiple vehicle models. This makes the conveyor line and hanger of the side panel need to meet the transportation requirements of side panels of multiple vehicle models. Since the lengths of side panels of different vehicle models vary greatly (for example, the length of the side panel of the Fit, an A0-class sedan, is about 2.7 meters, and the length of the side panel of the Accord, a B-class sedan, is about 3.3 meters), to ensure the stability during side panel transportation, the hanging wheels of the hanger will change the distance between the two hanging wheels according to the length and center of gravity position of the side panel. Because the hanger needs to circulate and transport on the conveyor line, it is impossible to connect air pipes or cables to the hanger, so it is impossible to use mechanisms such as cylinders or servo motors to adjust the distance between the hanger rollers. Therefore, there are generally two design schemes for the current side panel hanger. Scheme one is a dedicated design for the hanger of a vehicle model and is switched and used through a program. When adding a vehicle model, when the styling difference is too large to share the hanger with the previous vehicle model, a new hanger needs to be added at this time to form a hanger group, and they are arranged in the order of hanger of model A → hanger of model B → hanger of model C... → hanger of model A → hanger of model B → hanger of model C, and the type of hanger that stops at the stop position is controlled through a program. For example, when producing model A, by identifying the ID of the hanger, the hanger of model A stops each time it passes through the stop position, and the hangers of models B / C pass through the stop position empty. Although this technology can make the side panel conveyor line compatible with multiple vehicle models, it increases the number of hangers significantly and greatly reduces the buffer capacity of the conveyor line. Scheme two is the manual switching method of the hanger. When the production vehicle model is switched, the position of the hanger hanging wheel is switched manually. This scheme increases the labor hour cost and there is a certain danger in manual operation. Summary of the Invention

[0003] To overcome the above defects in the prior art, the present invention provides an automatic switching mechanism and a multi-model universal transportation device. The automatic switching mechanism can realize the automatic switching of the hanger model, enabling the hanger to adapt to the transportation of side panels of multiple vehicle models with high efficiency.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is:

[0005] An automatic switching mechanism includes a first transverse conveying mechanism, a driving mechanism, a movable suspension rod, a locking mechanism, and a transverse sliding mechanism; the driving mechanism is installed on the first transverse conveying mechanism, and the first transverse conveying mechanism drives the driving mechanism to slide back and forth horizontally; a plugging mechanism and a push plate are installed on the driving end of the driving mechanism, one end of the movable suspension rod is slidably connected to the transverse sliding mechanism, and the other end is detachably connected to the driving mechanism through the plugging mechanism; the first transverse conveying mechanism is arranged in parallel with the transverse sliding mechanism; a plurality of slots are arranged at intervals along the length direction of the transverse sliding mechanism; the locking mechanism is rotatably installed on the movable suspension rod, one end of the locking mechanism is a pushing end, and the other end is a locking end, and the locking end of the locking mechanism is detachably inserted into the slot; the driving mechanism drives the plugging mechanism and the push plate to move towards the movable suspension rod, the plugging mechanism is plugged with the movable suspension rod, the push plate contacts the pushing end of the locking mechanism, and pushes the locking mechanism to rotate, and the locking end of the locking mechanism is separated from the slot; the driving mechanism drives the plugging mechanism and the push plate to move away from the movable suspension rod, the plugging mechanism is separated from the movable suspension rod, the push plate is separated from the pushing end of the locking mechanism, and the locking end of the locking mechanism is inserted into the slot.

[0006] According to the above technical means, the first transverse conveying mechanism can drive the driving mechanism to move back and forth along the length direction of the first transverse conveying mechanism. The movable suspension rod is first slidably connected to the transverse sliding mechanism, and the position is locked through the locking mechanism at the same time; when it is necessary to adjust the position of the movable suspension rod on the transverse sliding mechanism, the driving mechanism first drives the plugging mechanism to be connected with the movable suspension rod. While the driving mechanism drives the plugging mechanism to move towards the movable suspension rod, the push plate also moves towards the movable suspension rod, pushing the locking mechanism to rotate. When the plugging mechanism is completely inserted into the movable suspension rod and connected to the movable suspension rod, at this time, the locking mechanism rotates to the maximum angle, the locking end of the locking mechanism is separated from the slot, and the movable suspension rod is in a movable state, that is, it can slide along the transverse sliding mechanism; at this time, the first transverse conveying mechanism drives the driving mechanism to move along the first transverse conveying mechanism again. During the movement of the driving mechanism, the movable suspension rod is driven to move along the transverse sliding mechanism. When it slides to the required position, that is, the position where another slot is located, it stops moving; the driving mechanism drives the plugging mechanism and the push plate to move away from the movable suspension rod, the push plate no longer contacts the pushing end of the locking mechanism, and the locking mechanism returns to its original position, that is, the locking end is inserted into the slot again to realize the locking of the movable suspension rod; through the above operations, the automatic switching of the position of the movable suspension rod can be realized without manual operation.

[0007] In one embodiment, an elastic member is further provided on the movable suspension rod. One end of the elastic member is fixed on the movable suspension rod, and the other end is connected to the locking end of the locking mechanism. By providing the elastic member, the locking end of the locking mechanism can always maintain a force of inserting towards the slot under the elastic force of the elastic member, that is, the locking end can be firmly inserted into the slot without loosening. In addition, it also enables the locking mechanism to automatically return to its original state (locking state). When the push plate is separated from the pushing end, the locking end can automatically return to its original state under the action of the elastic member.

[0008] In one embodiment, the locking mechanism is rotatably connected to the movable suspension rod through a rotating shaft, and a baffle for restricting the rotation angle of the locking mechanism is further provided on the movable suspension rod. By restricting the rotation angle of the movable suspension rod through the baffle, the maximum angle position is the position when the locking end is inserted into the slot, which can further ensure that the locking end can be firmly inserted into the slot and ensure that the locking mechanism can be locked.

[0009] In one embodiment, a first linear slide rail is provided on the lateral sliding mechanism, and a first slider is provided on the movable suspension rod. The movable suspension rod is slidably connected to the first linear slide rail through the first slider; the first lateral conveying mechanism includes a driving motor, a second linear slide rail, a lead screw, and a second slider; the second slider is slidably connected to the second linear slide rail, and the second slider is threadedly connected to the lead screw; the driving end of the driving motor is connected to the lead screw to drive the lead screw to rotate, thereby driving the second slider to slide back and forth along the second linear slide rail.

[0010] In one embodiment, a position detection sensor is further provided on the movable suspension rod. By detecting the current position of the movable suspension rod through the position detection sensor, the positioning of the movable suspension rod is realized. In this way, when adjusting the position of the movable suspension rod, during the movement of the movable suspension rod, it can be ensured whether it reaches the position that needs to be adjusted, and it can be ensured that the locking mechanism can be inserted into the slot.

[0011] In one embodiment, the plugging mechanism is a bolt; a socket is provided on the movable suspension rod; the bolt is inserted into the socket to be connected to the movable suspension rod.

[0012] In another embodiment, a multi-vehicle universal conveying device is further provided, which includes a second conveying mechanism, a gantry, a main frame, a first fixed hanging rod, a second fixed hanging rod, and the automatic switching mechanism described above; the lateral sliding mechanism is installed on the main frame, the first fixed hanging rod and the second fixed hanging rod are fixedly installed on the main frame, the first fixed hanging rod, the second fixed hanging rod and the movable hanging rod are arranged at intervals, and the second fixed hanging rod is located between the first fixed hanging rod and the movable hanging rod; a first roller is rotatably installed on the first fixed hanging rod; a guiding clip is installed on the second fixed hanging rod; a second roller is installed on the movable hanging rod; the gantry is erected on both sides of the second conveying mechanism, and the second conveying mechanism passes under the gantry; the main frame is connected to the second conveying mechanism, and the second conveying mechanism drives the main frame to move along the transportation direction of the second conveying mechanism; the first lateral conveying mechanism is horizontally installed on the top of the gantry. Among them, the main frame, the first fixed hanging rod, the second fixed hanging rod and the movable frame together form a universal hanging frame, and by adjusting the position of the movable hanging rod on the main frame, the universal hanging frame can be adapted to a variety of different vehicle models.

[0013] According to the above technical means, during use, the first fixed hanging rod is connected to the window position between the B-pillar and the A-pillar of the side panel through the first roller, the second fixed hanging rod clamps the B-pillar position of the side panel through the guiding clip, and the movable hanging rod is connected to the rear window position through the second roller; since the lengths from the B-pillar to the rear of the vehicle are different for different vehicle models, by adjusting the position of the movable hanging rod, the side panels of different vehicle models can be adapted.

[0014] Multiple universal hanging frames can be installed on the second conveying mechanism to simultaneously transport multiple side panels; when the model of the side panel changes, the hanging frame is transported to the position where the gantry is located, and through the cooperation of the first lateral conveying mechanism and the driving mechanism on the gantry, the position of the movable hanging rod is switched to adapt to different vehicle models.

[0015] In one of the embodiments, the guiding clip includes a mounting plate, a first arc-shaped guiding plate and a second arc-shaped guiding plate; the mounting plate is installed on the second fixed hanging rod, one end of the first arc-shaped guiding plate and one end of the second arc-shaped guiding plate are both fixedly installed on the mounting plate, and the first arc-shaped guiding plate and the second arc-shaped guiding plate are arranged at intervals.

[0016] In one of the embodiments, the second conveying mechanism is an accumulation chain conveying mechanism.

[0017] In one of the embodiments, an RFID tag is further provided on the main frame. The vehicle model information of the workpiece is written at the starting position of the side panel transmission, and data is read at the ending position of the transmission, so as to complete the information transfer of the vehicle model parts.

[0018] Compared with the prior art, the beneficial effects are as follows: An automatic switching mechanism and a multi-vehicle universal conveying device provided by the present invention can realize the automatic switching of the position of the movable suspension rod through the automatic switching device, thereby changing the distance between the movable suspension rod and the second fixed suspension rod, so as to adapt to the transportation of side wall parts of different vehicle models; the present invention can realize automatic switching, with high efficiency.

[0030] Embodiment 1:

[0031] Such as Figures 1 to 5As shown in the figure, an automatic switching mechanism includes a first transverse conveying mechanism 1, a driving mechanism 2, a movable hanging rod 3, a locking mechanism 4, and a transverse sliding mechanism 5. The driving mechanism 2 is installed on the first transverse conveying mechanism 1, and the first transverse conveying mechanism 1 drives the driving mechanism 2 to slide back and forth horizontally. An inserting mechanism 6 and a push plate 7 are installed on the driving end of the driving mechanism 2. One end of the movable hanging rod 3 is slidably connected to the transverse sliding mechanism 5, and the other end is detachably connected to the driving mechanism 2 through the inserting mechanism 6. The first transverse conveying mechanism 1 is arranged in parallel with the transverse sliding mechanism 5. A plurality of slots 8 are arranged at intervals along the length direction of the transverse sliding mechanism 5. The locking mechanism 4 is rotatably installed on the movable hanging rod 3. One end of the locking mechanism 4 is a pushing end 9, and the other end is a locking end 10. The locking end 10 of the locking mechanism 4 is detachably inserted into the slot 8. The driving mechanism 2 drives the inserting mechanism 6 and the push plate 7 to move towards the movable hanging rod 3. The inserting mechanism 6 is inserted into the movable hanging rod 3, and the push plate 7 contacts the pushing end 9 of the locking mechanism 4, pushing the locking mechanism 4 to rotate. The locking end 10 of the locking mechanism 4 is separated from the slot 8. The driving mechanism 2 drives the inserting mechanism 6 and the push plate 7 to move away from the movable hanging rod 3. The inserting mechanism 6 is separated from the movable hanging rod 3, the push plate 7 is separated from the pushing end 9 of the locking mechanism 4, and the locking end 10 of the locking mechanism 4 is inserted into the slot 8.

[0032] According to the above technical means, the first transverse conveying mechanism 1 can drive the driving mechanism 2 to move back and forth along the length direction of the first transverse conveying mechanism 1. The movable hanging rod 3 is first slidably connected to the transverse sliding mechanism 5, and at the same time, the position is locked through the locking mechanism 4. When it is necessary to adjust the position of the movable hanging rod 3 on the transverse sliding mechanism 5, the driving mechanism 2 first drives the inserting mechanism 6 to be connected to the movable hanging rod 3. While the driving mechanism 2 drives the inserting mechanism 6 to move towards the movable hanging rod 3, the push plate 7 also moves towards the movable hanging rod 3, pushing the locking mechanism 4 to rotate. When the inserting mechanism 6 is completely inserted into the movable hanging rod 3 and connected to the movable hanging rod 3, at this time, the locking mechanism 4 rotates to the maximum angle, and the locking end 10 of the locking mechanism 4 is separated from the slot 8, and the movable hanging rod 3 is in a movable state, that is, it can slide along the transverse sliding mechanism 5. At this time, the first transverse conveying mechanism 1 drives the driving mechanism 2 to move along the first transverse conveying mechanism 1 again. During the movement of the driving mechanism 2, the movable hanging rod 3 is driven to move along the transverse sliding mechanism 5. When it slides to the required position, that is, the position where another slot 8 is located, the movement stops. The driving mechanism 2 drives the inserting mechanism 6 and the push plate 7 to move away from the movable hanging rod 3. The push plate 7 no longer contacts the pushing end 9 of the locking mechanism 4, and the locking mechanism 4 returns to its original position, that is, the locking end 10 is inserted into the slot 8 again to lock the movable hanging rod 3. Through the above operations, the automatic switching of the position of the movable hanging rod 3 can be realized without manual operation.

[0033] As Figure 1 and Figure 2As shown, an elastic member 11 is further provided on the movable suspension rod 3. One end of the elastic member 11 is fixed on the movable suspension rod 3, and the other end is connected to the locking end 10 of the locking mechanism 4. By providing the elastic member 11, the locking end 10 of the locking mechanism 4 can always maintain a force of inserting towards the slot 8 under the elastic force of the elastic member 11, that is, the locking end 10 can be firmly inserted into the slot 8 without loosening. In addition, it also enables the locking mechanism 4 to automatically return to its original state (locking state). When the push plate 7 is separated from the pushing end 9, the locking end 10 can automatically return to its original state under the action of the elastic member 11.

[0034] In this embodiment, the driving mechanism 2 is preferably a driving cylinder. When the driving mechanism 2 does not extend, the locking mechanism 4 on the movable suspension rod 3 relies on the pulling force of the elastic member 11 to achieve the cooperation between the locking mechanism 4 and the slot 8, restricting the movement of the movable suspension rod 3 and achieving fixed positioning. When the driving cylinder extends, the push plate 7 on the driving cylinder touches the pushing end 9 of the locking mechanism 4, applying a pressure F2. Since F2 > the pulling force F1 of the elastic member 11, the locking mechanism 4 rotates, resulting in the separation of the locking end 10 of the locking mechanism 4 from the slot 8, and the movable suspension rod 3 can slide along with the driving cylinder.

[0035] As Figure 1 and Figure 2 As shown, the locking mechanism 4 is rotatably connected to the movable suspension rod 3 through a rotating shaft 12, and a baffle 13 for restricting the rotation angle of the locking mechanism 4 is further provided on the movable suspension rod 3. By restricting the rotation angle of the movable suspension rod 3 through the baffle 13, the position of the maximum angle is the position when the locking end 10 is inserted into the slot 8, which can further ensure that the locking end 10 can be firmly inserted into the slot 8 and ensure that the locking mechanism 4 can be locked.

[0036] In addition, a first linear slide rail is provided on the lateral sliding mechanism 5, and a first slider is provided on the movable suspension rod 3. The movable suspension rod 3 is slidably connected to the first linear slide rail through the first slider; the first lateral conveying mechanism 1 includes a driving motor, a second linear slide rail, a lead screw, and a second slider; the second slider is slidably connected to the second linear slide rail, and the second slider is threadedly connected to the lead screw; the driving end of the driving motor is connected to the lead screw to drive the lead screw to rotate, thereby driving the second slider to slide back and forth along the second linear slide rail.

[0037] Among them, a position detection sensor is further provided on the movable suspension rod 3. By detecting the current position of the movable suspension rod 3 through the position detection sensor, the positioning of the movable suspension rod 3 is realized. In this way, when adjusting the position of the movable suspension rod 3, during the movement of the movable suspension rod 3, it can be ensured whether it reaches the position that needs to be adjusted, and it can be ensured that the locking mechanism 4 can be inserted into the slot 8.

[0038] As Figure 1 and Figure 2As shown, the plugging mechanism 6 is a bolt; the movable suspension rod 3 is provided with a jack; the bolt is inserted into the jack to be connected with the movable suspension rod 3.
