[0033] Currently, in the automotive manufacturing industry, there are mainly two ways to handle the instrument panel skeleton in the instrument panel production line. One is manual handling, and the other is a combination of placing and transferring through hanging racks and manual walking handling. Both of these handling methods are applicable to environments with a short distance between production lines. In an environment with a long production line and a long distance between equipment placements, it is necessary to set up multiple sections of distances to place hanging racks for turnover. The operators need to walk back and forth to pick up the instrument panel skeleton, resulting in excessive walking waste during production operations for the operators. Moreover, when manually handling, the operator needs to carry a 6KG instrument panel skeleton, which causes a heavy load on the operator during daily operations and low work efficiency. The main purpose of the present utility model is to propose a handling device 100, aiming to solve the problem of how to reduce the workload of the staff in handling the instrument panel skeleton and improve work efficiency.

[0034] Please refer to Figures 1 to 3, in an embodiment of the present utility model, the handling device 100 includes a frame 1, a first tray 2 and a driving mechanism 3. The frame 1 includes an inlet end 111 and an outlet end 112 which are oppositely arranged; the first tray 2 is movably connected to the frame 1 so that the first tray 2 can move horizontally relative to the frame 1, and the first tray 2 is used for accommodating the material 200; the driving mechanism 3 includes a driving component 31 and a connecting component 32. The driving component 31 includes a lifting driving member 311, a first counterweight 312 and a second counterweight 313. The output end of the lifting driving member 311 is connected to the first counterweight 312, and the mass of the first counterweight 312 is greater than the mass of the second counterweight 313. The connecting component 32 includes a first connecting rope 321 and a second connecting rope 322. The first counterweight 312 includes a first lifting position 3121 and a first lowering position 3122, and the second counterweight 313 includes a second lifting position 3131 and a second lowering position 3132. Two ends of the first connecting rope 321 are respectively connected to the first counterweight 312 and the first tray 2, and two ends of the second connecting rope 322 are respectively connected to the second counterweight 313 and the first tray 2; the first counterweight 312 can descend from the first lifting position 3121 to the first lowering position 3122 under the action of gravity and drive the first tray 2 to move towards the outlet end 112 through the first connecting rope 321, and the first tray 2 drives the second counterweight 313 to rise from the second lowering position 3132 to the second lifting position 3131 through the second connecting rope 322; the lifting driving member 311 drives the first counterweight 312 to rise from the first lowering position 3122 to the first lifting position 3121, and the second counterweight 313 can descend from the second lifting position 3131 to the second lowering position 3132 under the action of gravity and drive the first tray 2 to move towards the inlet end 111 through the second connecting rope 322.

[0035] In the embodiment of the present utility model, the driving mechanism 3 is used to drive the first tray 2 to move horizontally relative to the frame 1. The first tray 2 is used to accommodate the instrument panel skeleton, so as to realize the long-distance handling of the instrument panel skeleton. Specifically, the first counterweight 312 is connected to the first tray 2 through the first connecting rope 321, and the second counterweight 313 is connected to the first tray 2 through the second connecting rope 322. That is, the first counterweight 312 is connected to the second counterweight 313 through the first connecting rope 321, the first tray 2 and the second connecting rope 322, and the mass of the first counterweight 312 is greater than that of the second counterweight 313. The first counterweight 312 can descend from the first lifting position 3121 to the first descending position 3122 under the action of gravity and drive the first tray 2 to move from the feeding end 111 to the discharging end 112 through the first connecting rope 321, so as to realize the handling of the instrument panel skeleton. At the same time, the first tray 2 drives the second counterweight 313 to rise from the second descending position 3132 to the second lifting position 3131 through the second connecting rope 322; after the instrument panel skeleton is unloaded from the first tray 2, the lifting driving member 311 is started. Since the output end of the lifting driving member 311 is connected to the first counterweight 312, the lifting driving member 311 can drive the first counterweight 312 to rise from the first descending position 3122 to the first lifting position 3121. At the same time, the second counterweight 313 can descend from the second lifting position 3131 to the second descending position 3132 under the action of gravity and drive the first tray 2 to move towards the feeding end 111 through the second connecting rope 322, so as to realize the reciprocating movement of the first tray 2; compared with manual handling of articles, the handling device 100 can realize the long-distance handling of articles, without manual handling and long-distance walking, greatly reducing the workload of the staff and effectively improving the work efficiency.

[0036] The technical solution of the present utility model adopts the lifting driving member 311, the first counterweight 312 and the second counterweight 313. By using the fact that the first counterweight 312 can move downward relative to the frame 1 under the action of gravity, the first tray 2 can be moved from the feeding end 111 to the right to the discharging end 112, so as to realize the handling of the instrument panel skeleton; by using the lifting driving member 311 to drive the first counterweight 312 to move upward relative to the frame 1, the second counterweight 313 can move downward relative to the frame 1 under the action of gravity, so as to move the first tray 2 from the discharging end 112 to the feeding end 111, thereby realizing the reciprocating movement of the first tray 2 and enabling multiple handling of the instrument panel skeleton; and the length of the frame 1 can be selected according to actual needs. The handling device 100 can realize the long-distance handling of articles, without manual handling and long-distance walking, greatly reducing the workload of the staff and effectively improving the work efficiency.

[0037] In this embodiment, the lifting driving member 311 may adopt a cylinder in the existing structure, or other structures such as a pneumatic slider or a lead screw mechanism. This embodiment does not limit the selection of the lifting driving member 311.

[0038] Please refer to Figures 3 to 5 , in an embodiment, the frame 1 includes a frame body 11 and a mounting frame 12. The mounting frame 12 includes a first vertical rod 121 and a second vertical rod 122. Both the first vertical rod 121 and the second vertical rod 122 are connected to the frame body 11. A first guide rail 1211 is provided on the first vertical rod 121, and a second guide rail (not shown in the figure) is provided on the second vertical rod 122. Both the first guide rail 1211 and the second guide rail extend in the vertical direction. A first roller 3123a is provided on the first counterweight 312, and a second roller (not shown in the figure) is provided on the second counterweight 313. The first roller 3123a is in rolling cooperation with the first guide rail 1211, and the second roller is in rolling cooperation with the second guide rail. Specifically, to improve the smoothness of the relative movement of the first counterweight 312 and the second counterweight 313 along the vertical direction with respect to the frame 1, by providing the first roller 3123a in rolling cooperation with the first guide rail 1211, it can prevent the first counterweight 312 from shaking in the horizontal direction when rising or falling. By providing the second roller in rolling cooperation with the second guide rail, it can prevent the second counterweight 313 from shaking in the horizontal direction when rising or falling, thereby improving the smoothness of the movement of the first counterweight 312 and the second counterweight 313.

[0039] In one embodiment, the rack 1 further includes a first pulley assembly 13. The first pulley assembly 13 includes a plurality of first fixed pulleys 131. The plurality of first fixed pulleys 131 are all connected to the frame body 11. The plurality of first fixed pulleys 131 are arranged at intervals in the horizontal direction. The positions of the plurality of first fixed pulleys 131 are higher than the positions where the first connecting rope 321 is connected to the first counterweight 312 and the positions where the first connecting rope 321 is connected to the first tray 2. The first counterweight 312 includes a first counterweight block 3123 and a plurality of first movable pulleys 3124. The plurality of first movable pulleys 3124 are all connected to the first counterweight block 3123. The plurality of first movable pulleys 3124 are arranged at intervals in the horizontal direction. A first roller 3123a is provided on the first counterweight block 3123. One end of the first connecting rope 321 is connected to the first counterweight block 3123, and the other end of the first connecting rope 321 is alternately wound around the chutes of the first fixed pulleys 131 and the chutes of the first movable pulleys 3124 in sequence and then connected to the first tray 2. Specifically, to achieve long-distance transportation, the length of the rack 1 is relatively large, and the moving stroke of the first tray 2 relative to the rack 1 is relatively long. The first counterweight block 3123 can descend from the first lifting position 3121 to the first lowering position 3122 under the action of gravity and drive the first tray 2 to move towards the discharge end 112 through the first connecting rope 321, that is, the stroke of the first counterweight block 3123 driving the first connecting rope 321 to descend along the first vertical rod 121 from the first lifting position 3121 to the first lowering position 3122 is equal to the moving stroke of the first tray 2 relative to the rack 1. To facilitate installation and use and reduce the overall size of the handling device 100, by arranging a plurality of first fixed pulleys 131 and a plurality of first movable pulleys 3124, the running stroke of the first counterweight block 3123 driving the first connecting rope 321 is increased, thereby shortening the size of the first vertical rod 121. In this embodiment, the length of the rack 1 is 16 m, the height of the first vertical rod 121 is 2 m, the number of the first fixed pulleys 131 is 4, the number of the second movable pulleys 15 is 4. One end of the first connecting rope 321 is connected to the first counterweight block 3123, and the other end of the first connecting rope 321 is alternately wound around the chutes of the first fixed pulleys 131 and the chutes of the first movable pulleys 3124 in sequence and then connected to the first tray 2. Thus, the 2-m stroke of the first counterweight block 3123 descending along the first vertical rod 121 from the first lifting position 3121 to the first lowering position 3122 can drive the first connecting rope 321 to move a 16-m stroke, so that the first tray 2 can move 16 m relative to the rack 1, and the first tray 2 moves from the feeding end 111 to the discharge end 112 to complete the handling of the instrument panel skeleton. The length of the rack 1, the number of the first fixed pulleys 131, and the number of the first movable pulleys 3124 can be selected according to actual needs, and the length of the rack 1, the number of the first fixed pulleys 131, and the number of the first movable pulleys 3124 are not limited in this example.Moreover, the positions of multiple first fixed pulleys 131 need to be higher than the positions where the first connecting rope 321 is connected to the first counterweight 3123 and the position where the first connecting rope 321 is connected to the first tray 2, so that the first counterweight 3123 can provide a force for the first tray 2 to move from the feeding end 111 to the discharging end 112 through the first connecting rope 321.;

[0040] In an embodiment, the frame 1 further includes a first connecting frame 14 and a second movable pulley 15 that are connected to each other. The first connecting frame 14 is rollingly connected to the frame body 11 so that the first connecting frame 14 can move relative to the frame body 11 in the vertical direction. The first connecting rope 321 includes a first section 3211 and a second section 3212. One end of the first section 3211 is connected to the first counterweight 3123, and the other end of the first section 3211 is alternately wound around the chute of the first fixed pulley 131 and the chute of the first movable pulley 3124 and then connected to one end of the second section 3212. The other end of the second section 3212 is wound around the chute of the second movable pulley 15 and then connected to the first tray 2. Multiple first fixed pulleys 131 are correspondingly arranged with the first vertical rod 121; specifically, to prevent the first counterweight 3123 from running too fast and causing the first connecting rope 321 to curl, a second movable pulley 15 is provided on the first connecting frame 14 to tighten the first connecting rope 321 through the second movable pulley 15 and prevent it from curling. The first connecting frame 14 is rollingly connected to the frame body 11 so that the first connecting frame 14 can move relative to the frame body 11 in the vertical direction. When the handling device 100 operates normally, the second movable pulley 15 is at the highest position; when the first counterweight 3123 runs too fast, at this time, the moving speed of the first connecting rope 321 is less than the moving speed of the first counterweight 3123, and the first section 3211 will curl. Since one end of the second section 3212 is connected to the first section 3211 and the other end of the second section 3212 is wound around the chute of the second movable pulley 15 and then connected to the first tray 2, at this time, the second movable pulley 15 can move relative to the frame 1 in the vertical direction under its own gravity, so that the first connecting rope 321 is tightened and the handling device 100 can operate normally; and according to the running speed of the first counterweight 3123, the second movable pulley 15 will automatically adjust its height to keep the first connecting rope 321 in a tightened state, without manual adjustment, and the structure is simple and highly reliable.

[0041] In one embodiment, the rack 1 further includes a second pulley assembly 16. The second pulley assembly 16 includes a plurality of second fixed pulleys 161. The plurality of second fixed pulleys 161 are all connected to the frame body 11. The plurality of second fixed pulleys 161 are arranged at intervals in the horizontal direction. The positions of the plurality of second fixed pulleys 161 are higher than the positions where the second connecting rope 322 is connected to the second counterweight 313 and the position where the second connecting rope 322 is connected to the first tray 2. The second counterweight 313 includes a second counterweight block 3133 and a plurality of third movable pulleys 3134. The plurality of third movable pulleys 3134 are all connected to the second counterweight block 3133. The plurality of third movable pulleys 3134 are arranged at intervals in the horizontal direction. A second roller is provided on the second counterweight block 3133. One end of the second connecting rope 322 is connected to the second counterweight block 3133. The other end of the second connecting rope 322 is alternately wound around the chutes of the second fixed pulleys 161 and the chutes of the third movable pulleys 3134 in sequence and then connected to the first tray 2. Specifically, to achieve long-distance transportation, the length of the rack 1 is relatively large, and the moving stroke of the first tray 2 relative to the rack 1 is relatively long. The second counterweight block 3133 can descend from the second lifting position 3131 to the second lowering position 3132 under the action of gravity and drive the first tray 2 to move towards the feeding end 111 through the second connecting rope 322. That is, the stroke of the second counterweight block 3133 driving the second connecting rope 322 to descend from the second lifting position 3131 to the second lowering position 3132 along the second vertical rod 122 is equal to the moving stroke of the first tray 2 relative to the rack 1. To facilitate installation and use and reduce the overall size of the handling device 100, by setting a plurality of second fixed pulleys 161 and a plurality of third movable pulleys 3134, the running stroke of the second counterweight block 3133 driving the second connecting rope 322 is increased, thereby shortening the size of the second vertical rod 122. In this embodiment, the length of the rack 1 is 16 m, the height of the second vertical rod 122 is 2 m, the number of the second fixed pulleys 161 is 4, the number of the third movable pulleys 3134 is 4. One end of the second connecting rope 322 is connected to the second counterweight block 3133. The other end of the second connecting rope 322 is alternately wound around the chutes of the second fixed pulleys 161 and the chutes of the third movable pulleys 3134 in sequence and then connected to the first tray 2. Thus, the 2 m stroke of the second counterweight block 3133 descending from the second lifting position 3131 to the second lowering position 3132 along the second vertical rod 122 can drive the second connecting rope 322 to move a 16 m stroke, so that the first tray 2 can move 16 m relative to the rack 1, and the first tray 2 moves from the feeding end 111 to the discharging end 112, completing the return movement of the first tray 2. The number of the second fixed pulleys 161 and the number of the third movable pulleys 3134 can be selected according to actual needs. In this example, the number of the second fixed pulleys 161 and the number of the third movable pulleys 3134 are not limited.Moreover, the positions of multiple second fixed pulleys 161 need to be higher than the positions where the second connecting rope 322 is connected to the second counterweight 3133 and the position where the second connecting rope 322 is connected to the first tray 2, so that the second counterweight 3133 can provide a force for the first tray 2 to move from the discharge end 112 to the feed end 111 through the second connecting rope 322.

[0042] In an embodiment, the frame 1 further includes a second connecting frame 17 and a fourth movable pulley 18 that are connected to each other. The second connecting frame 17 is connected to the frame body 11 in a rolling manner, so that the second connecting frame 17 can move relative to the frame body 11 in the vertical direction. The second connecting rope 322 includes a third section 3221 and a fourth section 3222. One end of the third section 3221 is connected to the second counterweight 3133, and the other end of the third section 3221 is alternately wound around the chute of the second fixed pulley 161 and the chute of the third movable pulley 3134 and then connected to one end of the fourth section 3222. The other end of the fourth section 3222 is wound around the chute of the fourth movable pulley 18 and then connected to the first tray 2. Multiple second fixed pulleys 161 are correspondingly arranged with the second vertical rod 122; specifically, to prevent the second counterweight 3133 from running too fast and causing the second connecting rope 322 to curl, a fourth movable pulley 18 is provided on the second connecting frame 17 to tighten the second connecting rope 322 through the fourth movable pulley 18 to prevent it from curling. The second connecting frame 17 is connected to the frame body 11 in a rolling manner, so that the second connecting frame 17 can move relative to the frame body 11 in the vertical direction. When the handling device 100 operates normally, the fourth movable pulley 18 is at the highest position; when the second counterweight 3133 runs too fast, at this time, the moving speed of the second connecting rope 322 is less than the moving speed of the second counterweight 3133, and the third section 3221 will curl. Since one end of the fourth section 3222 is connected to the third section 3221 and the other end of the fourth section 3222 is wound around the chute of the fourth movable pulley 18 and then connected to the first tray 2, at this time, the fourth movable pulley 18 can move relative to the frame 1 in the vertical direction under its own gravity, so that the second connecting rope 322 is tightened, enabling the handling device 100 to operate normally; and according to the running speed of the second counterweight 3133, the fourth movable pulley 18 will automatically adjust its height to keep the second connecting rope 322 in a tightened state, without manual adjustment, with a simple structure and high reliability.

[0043] In this embodiment, the frame 1 includes a first pulley assembly 13, a second pulley assembly 16, a first connecting frame 14, a second movable pulley 15, a second connecting frame 17, and a fourth movable pulley 18. By providing the first pulley assembly 13 and the second pulley assembly 16, the sizes of the first vertical rod 121 and the second vertical rod 122 can be shortened simultaneously, thereby reducing the overall size of the handling device 100 and facilitating installation and use. By providing the first connecting frame 14, the second movable pulley 15, the second connecting frame 17, and the fourth movable pulley 18, the first connecting rope 321 and the second connecting rope 322 can be kept in a tensioned state, enabling the handling device 100 to operate normally.

[0044] In one embodiment, a third guide rail (not shown in the figure) is provided on the frame 1, and the third guide rail extends in the horizontal direction. A third roller (not shown in the figure) is provided on the first tray 2, and the third roller is in rolling cooperation with the third guide rail. Specifically, to improve the stability of the first tray 2 moving relative to the frame 1 in the horizontal direction, a third guide rail is provided on the frame 1, and a third roller is provided on the first tray 2. The stability of the movement of the first tray 2 is achieved through the rolling cooperation between the third roller and the third guide rail, ensuring the reliable operation of the handling device 100.

[0045] In one embodiment, the handling device 100 further includes a support frame 4. The support frame 4 includes a frame body 41 and a second tray 42. One end of the frame body 41 is movably connected to the frame 1, and the other end of the frame body 41 is connected to the second tray 42, enabling the second tray 42 to move relative to the frame 1 in the horizontal direction through the frame body 41. The second tray 42 is disposed above the first tray 2, and the frame body 41 is provided with a through hole 411 for the first tray 2 to pass through. Specifically, to expand the application range of the handling device 100 and enable the handling device 100 to be compatible with the handling of instrument panel skeletons of multiple vehicle models, the handling device 100 further includes a support frame 4. Both the first tray 2 and the second tray 42 are used to accommodate the instrument panel skeletons. The frame body 41 can move relative to the frame 1 in the horizontal direction under the push of an operator, thereby completing the handling of the instrument panel skeletons. And to prevent interference between the first tray 2 and the frame body 41 when moving relative to the frame 1, the frame body 41 is further provided with a through hole 411 for the first tray 2 to pass through, so as to ensure that both the first tray 2 and the frame body 41 can move relative to the frame 1. Different vehicle models' instrument panel skeletons are placed on the second tray 42, thereby completing the handling of instrument panel skeletons of different vehicle models. It should be noted that since there are differences in the moving strokes of instrument panel skeletons of different vehicle models, the movement of the frame body 41 is independent of the first tray 2, and the two do not interfere with each other.

[0046] In one embodiment, a fourth roller (not shown in the figure) is provided on the support body 41, and a fourth guide rail (not shown in the figure) is provided on the frame 1. The fourth guide rail is arranged in the horizontal direction, and the fourth roller is in rolling cooperation with the fourth guide rail. Specifically, in order to improve the stability of the relative movement of the support body 41 along the horizontal direction with respect to the frame 1, a fourth guide rail is provided on the frame 1, and the fourth roller is in rolling cooperation with the fourth guide rail. The stability of the movement of the second tray 42 is achieved through the rolling cooperation of the fourth roller and the fourth guide rail, ensuring the reliable operation of the handling device 100.
