Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing, and particularly to a conveying system for a suede-like ceiling of a new energy vehicle. Background Art

[0002] The automobile ceiling is a crucial part of the interior of the whole vehicle. In addition to internal decoration, it can effectively play roles such as heat insulation and sound insulation. The suede-like ceiling is a commonly used ceiling for current new energy vehicles. The suede-like ceiling is large in volume by itself, and the key component material of the ceiling is polyurethane foam material, which is prone to bending due to concentrated stress during placement and transportation, and has high requirements for tooling.

[0003] The prior art Chinese invention patent with the authorization number CN114988109B proposes an automatic loading device for an automobile ceiling. The loading device includes a frame and a loading mechanism, and the loading mechanism is used to send the horizontally placed automobile ceiling into the inner side of the vehicle frame to complete the loading operation of the automobile ceiling. In order to convey the suede-like ceiling of the new energy vehicle from the warehouse to the above-mentioned ceiling loading mechanism, a conveying system for the suede-like ceiling of the new energy vehicle is also required. Currently, the AVG (Automated Guided Vehicle) trolley system is often used as a conveying system for interior decorations and other components in automobile assembly plants. A variety of AVG trolleys are disclosed in the prior art. For example, the Chinese invention patent with the authorization number CN119079542B proposes an automatic material taking mechanism for automobile interior decoration processing, including an AGV vehicle body. Driving tracks are installed on both sides of the bottom of the AGV vehicle body. Swing side arms are fixed on both sides of the AGV vehicle body through bearings. The same horizontally arranged sliding end frame is fixed at one end of the two swing side arms. A driving top slider is slidably installed at the bottom of the sliding end frame. During the movement of the present invention, the positions of the suction material boxes on both sides are aligned with the top of the interior decoration panel to be taken. When taking materials from the horizontal interior decoration panel, the suction material box remains horizontal without adjustment. After sucking the interior decoration panel through the suction plate at the bottom, the swing side arm is lifted to perform the work of taking and delivering the interior decoration panel, and the AGV vehicle body moves along the set route.

[0004] However, the use of a swing arm as a material taking mechanism on the above-mentioned AGV vehicle body has a fixed length and does not have a telescopic function, resulting in a limited length of the vehicle body it extends, which is not suitable for automobile ceilings with a large length. If the length of the swing arm is increased, the overall size of the AGV vehicle body will be increased, so improvement is needed. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a conveying system for a suede-like ceiling of a new energy vehicle, in which the grasping structure has a telescopic function, is suitable for automobile ceilings with a large length, and has good practicability.

[0006] A conveying system for a faux suede ceiling of a new energy vehicle according to the present invention includes a vehicle body, a frame, and a grasping component. The frame is installed on the vehicle body. It also includes two downward chutes, two first racks, two second racks, two first motors, and two first gears. The frame is basket-shaped, and a plurality of ceiling loading stations are installed inside the frame. A pick-and-place opening is provided on one side of the frame facing the advancing direction of the vehicle body. The two downward chutes are respectively installed on the left and right sides of the top of the frame. The two first racks are respectively slidably installed on the two downward chutes. The two second racks are respectively slidably installed on the two first racks. The two second racks are respectively arranged in an upper and lower stacked manner with the two first racks. The two first motors are respectively installed on the left and right sides above the pick-and-place opening of the frame. The output shafts of the two first motors are respectively concentrically installed with two first gears. The grasping component is installed between the two second racks. When the grasping component needs to extend, the first gear on the left first meshes with the second rack on the left and then meshes with the first rack on the left. At the same time, the first gear on the right first meshes with the second rack on the right and then meshes with the first rack on the left to drive. The conveying system is composed of a plurality of vehicle bodies and a plurality of frames. When taking materials, the vehicle body drives the frame to move into the warehouse and reach the designated position. The faux suede ceiling is placed at the designated position by the staff. The two first motors drive the two first gears to rotate synchronously. The two first gears first mesh with the two second racks, so as to extend the two second racks and the grasping component forward through the pick-and-place opening of the frame. When the two second racks respectively reach the outer ends of the two first racks, the two second racks no longer extend and drive the two first racks to extend forward along the two downward chutes respectively, so that the two first gears disengage from the two second racks and respectively mesh with the two first racks, thereby driving the two first racks to continue to extend forward. Furthermore, the two first racks and the two second racks form a double-stage telescopic structure. On this basis, setting a plurality of first racks on the same side can realize a multi-stage telescopic structure, so that the distance that the grasping component extends out of the frame is greater. The grasping component is extended to the designated position, and the grasping component adsorbs and grasps the middle part of the faux suede ceiling. The two first motors drive the two first gears to reverse. The two first gears first mesh to drive the two first racks to contract along the two downward chutes towards the frame respectively. When the two first racks disengage from the two first gears, the two second racks mesh with the two first gears again, so that the two second racks drive the grasping component to contract along the two first racks into the frame. Furthermore, the grasping component drives the faux suede ceiling to enter the interior of the frame through the pick-and-place opening. The grasping component releases the faux suede ceiling, so that the faux suede ceiling is placed on the ceiling loading station, completing the automatic loading of the faux suede ceiling. The vehicle body drives the frame to move to the ceiling assembly station, and the reverse action takes out the faux suede ceiling and places it on the feeding station, completing the conveying of the faux suede ceiling. Compared with the prior art that uses a grasping structure with a telescopic function, it increases the length of the vehicle body where the grasping component extends, is suitable for automotive ceilings with a larger length, and does not increase the overall size of the AGV vehicle body, with good practicability.

[0007] Preferably, it further includes two bolts and two first springs. Through holes are provided at the rear ends of the two second racks. The two bolts are respectively inserted into the two through holes. The upper ends of the two first springs are respectively connected to the two bolts, and the lower ends of the two first springs are respectively connected to the two second racks. The elastic forces of the two first springs cause the lower ends of the two bolts to extend below the two second racks. Limit holes are provided at the front ends of the two first racks; rounded corners are provided at the lower ends of the two bolts. When the two second racks slide to the front ends of the two first racks respectively, the lower ends of the two bolts are respectively inserted into the limit holes of the two first racks under the elastic forces of the two first springs, so that the two second racks and the two first racks are respectively connected. The first gear continues to rotate and meshes with the overlapping parts of the second rack and the first rack at the same time, so that the two second racks can respectively drive the first rack to slide out along the two downward sliding grooves. When the two second racks are disengaged from the two first gears, the two first racks are respectively engaged with the two first gears, realizing reliable telescoping of the two second racks and the two first racks. When the two first gears rotate in reverse, the two first gears first mesh and drive the two first racks to slide into the interior of the frame along the two downward sliding grooves respectively. The first gear continues to rotate and meshes with the overlapping parts of the second rack and the first rack at the same time. When the two first racks reach the interior of the frame and are blocked, the two first racks are disengaged from the two first gears, and the two second racks are respectively engaged with the two first gears. The two first gears continue to rotate. Due to the action of the rounded corners at the lower ends of the two bolts, the connection force between the two first racks and the second rack is limited. When the relative force between the two second racks and the two first racks is greater than the connection force generated by the two bolts, the lower ends of the two bolts pop out of the limit holes of the two first racks respectively, so that the two second racks and the two first racks are disengaged, and at this time the two second racks can contract onto the two first racks, with good practicability.

[0008] Preferably, it further includes two first connecting rods, two second connecting rods, two second gears, two second motors and two third gears. The upper ends of the two first connecting rods are respectively rotatably connected to the two second racks, and the lower ends of the two first connecting rods are respectively rotatably connected to the left and right sides of the grasping component. The upper ends of the two second connecting rods are respectively rotatably connected to the two second racks, and the lower ends of the two second connecting rods are respectively rotatably connected to the left and right sides of the grasping component through rotating shafts. The two first connecting rods and the two second connecting rods are arranged in parallel, and the two first connecting rods and the two second connecting rods have the same length. The two second gears are respectively concentrically installed at the lower ends of the two second connecting rods, and the two second gears are respectively concentric with the two rotating shafts. The two second motors are installed on the grasping component, and the two third gears are respectively concentrically installed on the output shafts of the two second motors. The two third gears are respectively meshed with the two second gears; the two first connecting rods and the two second connecting rods form a four-bar linkage structure of a parallelogram. The two second motors respectively drive the two third gears to rotate. The two third gears respectively mesh and drive the two second gears to rotate. The two second gears respectively drive the two second connecting rods to rotate around the rotating shafts, so that the grasping component moves up and down relative to the two second racks, thereby adjusting the height of the grasping component, facilitating the adsorption and grasping of suede-like ceilings at different heights, and improving practicability.

[0009] Preferably, it further includes two slide rails, a cross beam, a magnetic attraction block, a vertical rod and an electromagnetic seat. The two slide rails are respectively installed on the left and right sides of the top of the frame. The two ends of the cross beam are respectively slidably connected to the two slide rails through sliders. A magnetic attraction block is arranged in the middle of the cross beam. The upper end of the vertical rod is connected to the cross beam, and the lower part of the vertical rod extends into the interior of the frame. The electromagnetic seat is installed on the rear ends of the two second racks through a bracket, and the electromagnetic seat is detachably and magnetically connected to the magnetic attraction block; when it is necessary to push the suede-like ceilings on multiple ceiling loading stations inside the frame out of the frame, the two second racks move backward, driving the electromagnetic seat to approach the cross beam, so that the electromagnetic seat is magnetically connected to the magnetic attraction block. The two second racks move forward, and the two second racks drive the cross beam to move forward along the two slide rails through the electromagnetic seat and the magnetic attraction block, so that the cross beam drives the vertical rod to move forward, so that the vertical rod pushes the multiple suede-like ceilings out of the frame through the picking and placing opening, realizing efficient blanking.

[0010] Preferably, the ceiling loading station includes a plurality of sub-supports, which are respectively installed on the left and right sides inside the frame. Each sub-support includes a column, a lower support rod, a middle support rod, an upper support rod, three torsion springs, a lower telescopic rod, an upper telescopic rod and a plurality of limit pins. The column is vertically installed inside the frame. The middle part of the lower support rod is rotatably connected to the lower part of the column through a lower hinge shaft. The middle part of the middle support rod is rotatably connected to the middle part of the column through a middle hinge shaft. The middle part of the upper support rod is rotatably connected to the upper part of the column through an upper hinge shaft. The inner ends of the lower support rod, the middle support rod and the upper support rod all face the middle of the frame. There are three torsion springs. One ends of the three torsion springs are respectively connected to the lower hinge shaft, the middle hinge shaft and the upper hinge shaft, and the other ends of the three torsion springs are respectively connected to the lower support rod, the middle support rod and the upper support rod. The elastic forces of the three torsion springs make the inner ends of the lower support rod, the middle support rod and the upper support rod tilt upward, and the inner end of the lower support rod is located inside the inner ends of the middle support rod and the upper support rod. The lower end of the lower telescopic rod is rotatably connected to the outer end of the lower support rod, and the upper end of the lower telescopic rod is rotatably connected to the outer end of the middle support rod. In the natural state, the lower telescopic rod is in a contracted state. The lower end of the upper telescopic rod is rotatably connected to the outer end of the middle support rod, and the upper end of the upper telescopic rod is rotatably connected to the outer end of the upper support rod. In the natural state, the upper telescopic rod is in a semi-contracted state. There are three limit pins, which are installed on the column. After loading the ceiling, the three limit pins respectively limit and support the inner ends of the lower support rod, the middle support rod and the upper support rod;In the natural state where the ceiling is not loaded inside the frame, the inner ends of the lower support rods extend into the interior of the frame beyond the inner ends of the middle support rods and the upper support rods. When the first suede-like ceiling is loaded downward from the upper part of the frame onto the inner ends of the multiple lower support rods, the inner ends of the multiple lower support rods rotate downward and are blocked by the multiple limit pins located below, so that the multiple lower support rods support and load a suede-like ceiling. When the multiple lower support rods rotate, since the multiple lower telescopic rods are in a contracted state, the outer ends of the multiple lower support rods respectively push the outer ends of the multiple middle support rods upward by a certain angle through the multiple lower telescopic rods, so that the inner ends of the multiple middle support rods respectively extend into the inner sides of the multiple upper support rods. When the outer ends of the multiple middle support rods rotate upward, the multiple upper telescopic rods are compressed to a contracted state. When the second suede-like ceiling is loaded downward from the upper part of the frame onto the inner ends of the multiple middle support rods, the inner ends of the multiple middle support rods rotate downward and are blocked by the multiple limit pins located in the middle, so that the multiple middle support rods support and load a suede-like ceiling. When the multiple middle support rods rotate, since the multiple upper telescopic rods are in a contracted state, the outer ends of the multiple middle support rods respectively push the outer ends of the multiple upper support rods upward by a certain angle through the multiple upper telescopic rods. At this time, the inner ends of the multiple upper support rods extend into the interior of the frame. When the third suede-like ceiling is loaded downward from the upper part of the frame onto the inner ends of the multiple upper support rods, the inner ends of the multiple upper support rods rotate downward and are blocked by the multiple limit pins located above, so that the multiple upper support rods support and load a suede-like ceiling. When the multiple upper support rods rotate, the outer ends of the multiple upper support rods respectively pull the multiple upper telescopic rods to extend, so that the multiple upper telescopic rods are in an extended state. When the above three suede-like ceilings are pushed out of the frame, the elastic force of the multiple torsion springs causes the multiple lower support rods, the multiple middle support rods and the multiple upper support rods to tilt and reset, realizing the partition support for the multiple suede-like ceilings, and having good practicability.

[0011] Preferably, it further includes multiple vertical shafts. The upper and lower ends of the multiple columns are respectively installed with vertical shafts, and the multiple vertical shafts are respectively rotationally connected to the bottom and top of the frame; the multiple columns are respectively rotationally installed inside the frame through the multiple vertical shafts. When the multiple columns rotate, they drive the inner ends of the multiple lower support rods, the multiple middle support rods and the multiple upper support rods to swing forward, assisting the discharge of the multiple suede-like ceilings and improving the discharge efficiency.

[0012] Preferably, it further includes multiple fourth gears and two third racks. The multiple fourth gears are respectively concentrically installed on the multiple vertical shafts at the upper ends of the multiple columns, and the two ends of the two cross beams are respectively installed with third racks. When the two third racks respectively meet the multiple fourth gears, they are meshed to drive the multiple columns to rotate; when the cross beam moves forward along the two slide rails, the vertical rod pushes the suede-like ceiling forward. When the cross beam drives the two third racks to meet the multiple fourth gears, the two third racks are respectively meshed with the multiple fourth gears, so that the multiple fourth gears respectively drive the multiple columns to rotate, so that the two columns respectively drive the inner ends of the multiple lower support rods, the multiple middle support rods and the multiple upper support rods to swing forward, assisting the vertical rod to push out the suede-like ceiling and improving the blanking efficiency.

[0013] Preferably, it further includes two wheel frames, four drive wheels, two transmission belts and two movable supporting rods. The two wheel frames are respectively vertically installed on the left and right sides inside the frame. Drive wheels are rotatably installed at the upper and lower ends of the two wheel frames. The two transmission belts are respectively sleeved on the four drive wheels on the two wheel frames. The two movable supporting rods are respectively installed on the outer walls of the two transmission belts. The inner ends of the two movable supporting rods both extend into the interior of the frame. The four drive wheels respectively drive the two transmission belts to rotate, and the two transmission belts respectively drive the two movable supporting rods to move cyclically, so as to make the two movable supporting rods cooperate to lift the suede-like roof released by the gripping component, and slowly place the suede-like roof on multiple lower supporting rods, multiple middle supporting rods or multiple upper supporting rods, reducing the collision of the suede-like roof and improving the reliability.

[0014] Preferably, it further includes a monitor, four servo motors, four swing arms and four traveling wheels. The monitor is installed at the front of the frame. The four servo motors are respectively symmetrically installed on the left and right sides of the vehicle body. One ends of the four swing arms are respectively connected to the output shafts of the four servo motors. The four traveling wheels are respectively rotatably installed at the other ends of the four swing arms. The monitor is used to monitor the relative position and angle between the frame and the gripping component and the suede-like roof at the designated position or the feeding station. The four traveling wheels rotate to drive the vehicle body to move. The four traveling wheels on the left and right sides rotate differentially to make the vehicle body turn, with good maneuverability. The four servo motors respectively adjust the tilting angles of the four swing arms, so as to adjust the attitude of the vehicle body, and further adjust the attitude of the gripping component, facilitating the gripping component to adsorb and grip the suede-like roof.

[0015] Preferably, it further includes a front slope plate, a push cylinder, a first lifting ring and a second lifting ring. The upper end of the front slope plate is rotatably connected to the front side wall of the vehicle body. The inner end of the push cylinder is rotatably connected to the vehicle body. The outer end of the push cylinder is rotatably connected to the front slope plate. The first lifting ring is installed at the rear end of the upper surface of the vehicle body. The second lifting ring is installed on the vertical rod. When it is necessary to move the frame onto the vehicle body, the push cylinder extends to push the lower end of the front slope plate forward. The two swing arms at the front are laid flat, and the two swing arms at the rear are erected, so that the front of the vehicle body is tilted lower and the rear is higher, making the lower end of the front slope plate contact the ground, forming a ramp with the front slope plate. Connect the two ends of the cable to the first lifting ring and the second lifting ring. After the two second racks adsorb the magnetic blocks through the electromagnetic seats and move forward, the cross beam and the vertical rod drive the second lifting ring to move forward, and then pull the cable forward. The reaction force slides the frame along the ramp formed by the front slope plate onto the vehicle body. The angles of the four swing arms are reset, making the vehicle body level, thus completing the automatic loading of the frame. It is also convenient for the frame to slide and unload when the vehicle body is tilted, improving the work efficiency.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By adopting a gripping structure with a telescopic function, the length of the gripping component extending out of the vehicle body is increased, which is applicable to the automotive roof with a larger length and does not increase the overall size of the AGV vehicle body, with good practicability.

Detailed implementation manners

[0032] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present invention is more thorough and comprehensive.

[0033] Example 1, as Figures 1 to 4 , Figure 7 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14As shown in the figure, a conveying system for the suede-like ceiling of a new energy vehicle includes a vehicle body 1, a frame 2 and a grasping component 3. The frame 2 is installed on the vehicle body 1. It also includes two downward chutes 4, two first racks 5, two second racks 6, two first motors 7 and two first gears 8. The frame 2 is basket-shaped, and multiple ceiling loading stations are installed inside the frame 2. A pick-and-place opening is provided on one side of the frame 2 facing the advancing direction of the vehicle body 1. The two downward chutes 4 are respectively installed on the left and right sides of the top of the frame 2. The two first racks 5 are respectively slidably installed on the two downward chutes 4. The two second racks 6 are respectively slidably installed on the two first racks 5. The two second racks 6 are respectively arranged in an up-and-down stacked manner with the two first racks 5. The two first motors 7 are respectively installed on the left and right sides above the pick-and-place opening of the frame 2. The output shafts of the two first motors 7 are respectively concentrically installed with the two first gears 8. The grasping component 3 is installed between the two second racks 6. When the grasping component 3 needs to extend, the first gear 8 on the left first meshes with the second rack 6 on the left and then meshes with the first rack 5 on the left. At the same time, the first gear 8 on the right first meshes with the second rack 6 on the right and then meshes with the first rack 5 on the left to drive. It also includes two pins 9 and two first springs 10. Through holes are provided at the rear ends of the two second racks 6. The two pins 9 are respectively inserted into the two through holes. The upper ends of the two first springs 10 are respectively connected to the two pins 9. The lower ends of the two first springs 10 are respectively connected to the two second racks 6. The elastic forces of the two first springs 10 cause the lower ends of the two pins 9 to extend below the two second racks 6. Limit holes are provided at the front ends of the two first racks 5.

[0034] The conveying system consists of multiple vehicle bodies 1 and multiple frames 2. When taking materials, the vehicle body 1 drives the frame 2 to move into the warehouse and reach the designated position. The suede-like ceiling is placed at the designated position by the staff. Two motors 7 drive two gears 8 to rotate synchronously. The two gears 8 first engage with two racks 6, so as to extend the two racks 6 and the grasping component 3 forward through the access opening of the frame 2. When the two racks 6 reach the outer ends of the two racks 1 5 respectively, the two racks 6 stop extending and drive the two racks 1 5 to extend forward along the two sliding grooves 4 respectively, so that after the two gears 8 are disengaged from the two racks 6, they engage with the two racks 1 5 respectively, thereby driving the two racks 1 5 to continue to extend forward. Furthermore, the two racks 1 5 and the two racks 6 form a double-stage telescopic structure. On this basis, setting multiple racks 1 5 on the same side can realize a multi-stage telescopic structure, enabling the grasping component 3 to extend a greater distance from the frame 2. The grasping component 3 is extended to the designated position, and the grasping component 3 adsorbs and grasps the middle of the suede-like ceiling. The two motors 7 drive the two gears 8 to reverse. The two gears 8 first engage to drive the two racks 1 5 to contract towards the frame 2 along the two sliding grooves 4 respectively. When the two racks 1 5 are disengaged from the two gears 8, the two racks 6 engage with the two gears 8 again, so that the two racks 6 drive the grasping component 3 to contract into the frame 2 along the two racks 1 5. Furthermore, the grasping component 3 drives the suede-like ceiling to enter the interior of the frame 2 through the access opening. The grasping component 3 releases the suede-like ceiling, so that the suede-like ceiling is placed on the ceiling loading station, completing the automatic loading of the suede-like ceiling. The vehicle body 1 drives the frame 2 to move to the ceiling assembly station, and performs reverse actions to take out the suede-like ceiling and place it on the feeding station, completing the conveying of the suede-like ceiling. Compared with the prior art that uses a grasping structure with a telescopic function, the length of the vehicle body 1 where the grasping component 3 extends is increased, which is applicable to automobile ceilings with a larger length and does not increase the overall size of the AGV vehicle body.

[0035] During the telescopic process of the two first racks 5 and the two second racks 6, rounded corners are provided at the lower ends of the two pins 9. When the two second racks 6 slide to the front ends of the two first racks 5 respectively, the lower ends of the two pins 9 are inserted into the limiting holes of the two first racks 5 under the elastic force of the two first springs 10 respectively, so that the two second racks 6 and the two first racks 5 are connected respectively. The first gear 8 continues to rotate and meshes with the stacked parts of the second rack 6 and the first rack 5 at the same time, so that the two second racks 6 can drive the first racks 5 to slide out along the two lower sliding grooves 4 respectively. When the two second racks 6 are disengaged from the two first gears 8, the two first racks 5 are meshed with the two first gears 8 respectively, realizing the reliable telescoping of the two second racks 6 and the two first racks 5. When the two first gears 8 rotate in reverse, the two first gears 8 first mesh and drive the two first racks 5 to slide into the interior of the frame 2 along the two lower sliding grooves 4 respectively. The first gear 8 continues to rotate and meshes with the stacked parts of the second rack 6 and the first rack 5 at the same time. When the two first racks 5 reach the interior of the frame 2 and are blocked, the two first racks 5 are disengaged from the two first gears 8, and the two second racks 6 are meshed with the two first gears 8 respectively. The two first gears 8 continue to rotate. Due to the action of the rounded corners at the lower ends of the two pins 9, the connection force between the two first racks 5 and the second rack 6 is limited. When the relative force between the two second racks 6 and the two first racks 5 is greater than the connection force generated by the two pins 9, the lower ends of the two pins 9 pop out of the limiting holes of the two first racks 5 respectively, so that the two second racks 6 and the two first racks 5 are disengaged, and at this time the two second racks 6 can contract onto the two first racks 5.

[0036] It further includes two first connecting rods 11, two second connecting rods 12, two second gears 13, two second motors 14 and two third gears 15. The upper ends of the two first connecting rods 11 are respectively rotatably connected to the two second racks 6, and the lower ends of the two first connecting rods 11 are respectively rotatably connected to the left and right sides of the grasping member 3. The upper ends of the two second connecting rods 12 are respectively rotatably connected to the two second racks 6, and the lower ends of the two second connecting rods 12 are respectively rotatably connected to the left and right sides of the grasping member 3 through rotating shafts. The two first connecting rods 11 and the two second connecting rods 12 are arranged in parallel, and the two first connecting rods 11 and the two second connecting rods 12 have the same length. The two second gears 13 are respectively concentrically installed at the lower ends of the two second connecting rods 12, and the two second gears 13 are respectively concentric with the two rotating shafts.

The lower end of the upper telescopic rod 27 is rotatably connected to the outer end of the middle support rod 23, and the upper end of the upper telescopic rod 27 is rotatably connected to the outer end of the upper support rod 24. In the natural state, the upper telescopic rod 27 is in a semi-contracted state. There are three limit pins 28, and the three limit pins 28 are installed on the vertical column 21. After loading the ceiling, the three limit pins 28 respectively limit and support the inner ends of the lower support rod 22, the middle support rod 23 and the upper support rod 24. It further includes a plurality of vertical shafts 29. The upper and lower ends of the plurality of vertical columns 21 are both installed with vertical shafts 29, and the plurality of vertical shafts 29 are respectively rotatably connected to the bottom and top of the frame 2.

[0041] When the framework 2 is in the natural state without a ceiling loaded inside, the inner ends of the lower supporting rods 22 extend into the interior of the framework 2 beyond the inner ends of the middle supporting rods 23 and the upper supporting rods 24. When the first suede-like ceiling is loaded downward from the upper part of the framework 2 onto the inner ends of the plurality of lower supporting rods 22, the inner ends of the plurality of lower supporting rods 22 rotate downward and are limited and blocked by a plurality of limiting pins 28 located below, so that the plurality of lower supporting rods 22 support and load a suede-like ceiling. When the plurality of lower supporting rods 22 rotate, since the plurality of lower telescopic rods 26 are in a contracted state, the outer ends of the plurality of lower supporting rods 22 respectively push the outer ends of the plurality of middle supporting rods 23 upward by a certain angle through the plurality of lower telescopic rods 26, so that the inner ends of the plurality of middle supporting rods 23 respectively extend into the inner sides of the plurality of upper supporting rods 24. When the outer ends of the plurality of middle supporting rods 23 rotate upward, the plurality of upper telescopic rods 27 are compressed to a contracted state.

When the plurality of upper supporting rods 24 rotate, the outer ends of the plurality of upper supporting rods 24 respectively pull the plurality of upper telescopic rods 27 to extend, so that the plurality of upper telescopic rods 27 are in an extended state. When the above three suede-like ceilings are pushed out of the framework 2, the elastic force of the plurality of torsion springs 25 causes the plurality of lower supporting rods 22, the plurality of middle supporting rods 23 and the plurality of upper supporting rods 24 to be inclined and reset, realizing the partitioned support for the plurality of suede-like ceilings.

[0042] The plurality of vertical columns 21 are respectively rotatably installed inside the framework 2 through a plurality of vertical shafts 29. When the cross beam 17 moves forward along the two slide rails 16, the vertical rod 19 pushes the suede-like ceiling forward.

[0043] It further includes two wheel carriers 32, four drive wheels 33, two transmission belts 34 and two movable support rods 35. The two wheel carriers 32 are respectively vertically installed on the left and right sides inside the frame 2. The upper and lower ends of the two wheel carriers 32 are rotatably installed with drive wheels 33. The two transmission belts 34 are respectively sleeved on the four drive wheels 33 on the two wheel carriers 32. The two movable support rods 35 are respectively installed on the outer walls of the two transmission belts 34. The inner ends of the two movable support rods 35 both extend into the interior of the frame 2;

[0044] The four drive wheels 33 respectively drive the two transmission belts 34 to rotate. The two transmission belts 34 respectively drive the two movable support rods 35 to move cyclically, so as to enable the two movable support rods 35 to cooperate to lift the suede-like roof released by the grasping member 3 and slowly place the suede-like roof on the multiple lower support rods 22, multiple middle support rods 23 or multiple upper support rods 24, reducing the collision of the suede-like roof.

[0045] Embodiment 3, as Figures 1 to 6 shown, on the basis of Embodiment 1, it further includes a monitor 36, four servo motors 37, four swing arms 38 and four traveling wheels 39. The monitor 36 is installed at the front of the frame 2. The four servo motors 37 are respectively symmetrically installed on the left and right sides of the vehicle body 1. One ends of the four swing arms 38 are respectively connected to the output shafts of the four servo motors 37. The four traveling wheels 39 are respectively rotatably installed at the other ends of the four swing arms 38; It further includes a front slope plate 40, a push cylinder 41, a first lifting ring 42 and a second lifting ring 43.

The outer end of the push cylinder 41 is rotatably connected to the front slope plate 40. The first lifting ring 42 is installed at the rear end of the upper end surface of the vehicle body 1. The second lifting ring 43 is installed on the vertical rod 19.

[0046] The monitor 36 is used to monitor the relative positions and angles of the frame 2 and the grasping component 3 with the suede ceiling at the specified position or the loading station. The four traveling wheels 39 rotate to drive the vehicle body 1 to move. The differential rotation of the four traveling wheels 39 on the left and right sides enables the vehicle body 1 to turn, with good maneuverability. The four servo motors 37 respectively adjust the tilting angles of the four swing arms 38, thereby adjusting the attitude of the vehicle body 1 and further adjusting the attitude of the grasping component 3, facilitating the adsorption and grasping of the suede ceiling by the grasping component 3. When the frame 2 needs to be moved onto the vehicle body 1, the push cylinder 41 extends to push the lower end of the front slope plate 40 forward. The two swing arms 38 located in the front are laid flat, and the two swing arms 38 located in the rear are erected, so that the front of the vehicle body 1 is low and the rear is high, causing the lower end of the front slope plate 40 to contact the ground, forming a ramp with the front slope plate 40. Connect the two ends of the cable to the lifting ring one 42 and the lifting ring two 43. The two racks two 6 move forward after adsorbing the magnetic attraction block 18 through the electromagnetic seat 20, causing the cross beam 17 and the vertical rod 19 to drive the lifting ring two 43 to move forward, and then pulling the cable forward. The reaction force slides the frame 2 along the ramp formed by the front slope plate 40 onto the vehicle body 1. The angles of the four swing arms 38 are reset, causing the vehicle body 1 to be laid flat, thus completing the automatic loading of the frame 2. It is also convenient for the frame 2 to slide and unload when the vehicle body 1 is tilted.

[0047] Such as Figures 1 to 14As shown in the figure, in the working process of a suede-like roof conveying system for new energy vehicles according to the present invention, first, the vehicle body 1 drives the frame 2 to move into the warehouse and reach a designated position. The suede-like roof is placed at the designated position by the staff. The monitor 36 monitors the relative position and angle between the frame 2 and the grasping component 3 and the suede-like roof, and adjusts the postures of the vehicle body 1 and the grasping component 3. Then, two first motors 7 drive two first gears 8 to rotate synchronously. The two first gears 8 first engage with two second racks 6, so as to extend the two second racks 6 and the grasping component 3 forward through the loading and unloading opening of the frame 2. When the two second racks 6 reach the outer ends of the two first racks 5 respectively, the two second racks 6 stop extending and drive the two first racks 5 to extend forward along the two downward sliding grooves 4 respectively, so that after the two first gears 8 are disengaged from the two second racks 6, they respectively engage with the two first racks 5, thereby driving the two first racks 5 to continue to extend forward and extending the grasping component 3 to the designated position. Then, the grasping component 3 descends to adsorb and grasp the middle part of the suede-like roof. The two first motors 7 drive the two first gears 8 to reverse. The two first gears 8 first engage to drive the two first racks 5 to contract along the two downward sliding grooves 4 towards the frame 2 respectively. When the two first racks 5 are disengaged from the two first gears 8, the two second racks 6 engage with the two first gears 8 again, so that the two second racks 6 drive the grasping component 3 to contract into the frame 2 along the two first racks 5, and further enable the grasping component 3 to drive the suede-like roof to enter the interior of the frame 2 through the loading and unloading opening. The grasping component 3 releases the suede-like roof. The two moving support rods 35 cooperate to support the suede-like roof released by the grasping component 3, and sequentially and slowly place a plurality of suede-like roofs on a plurality of lower support rods 22, a plurality of middle support rods 23 or a plurality of upper support rods 24, completing the automatic loading of the suede-like roof. Finally, the vehicle body 1 drives the frame 2 to move to the roof assembly station, and performs reverse actions to take out the suede-like roof and place it on the feeding station, completing the automatic conveying of the suede-like roof.

[0048] The main functions achieved by the present invention are:
