Description

Technical Field

[0001] The utility model relates to the technical field of grabbing tooling, in particular to a spacing adjustment mechanism for coil material grabbing equipment. Background Art

[0002] With the growing demand for energy conservation, electric vehicles have become an important development direction for the automotive industry in the future. However, the limited capacity of power batteries and the slow charging time of power batteries have also restricted the development of electric vehicles. Battery swapping technology has successfully solved the problem of electric vehicle range. During the battery swapping process, the removal and installation of the battery pack has become the most important part of the battery swapping technology operation. During the battery swapping process, the battery pack on the vehicle needs to be removed and transferred to the charging cabinet, and then the new battery pack is grabbed from the charging cabinet and installed in the battery compartment of the vehicle.

[0003] However, the battery packs in different new energy vehicles are of different sizes, and conventional manipulators are unable to grasp them. The existing practice is to use ropes and cranes, manually fix the battery packs with ropes and cranes, hoist them to the disassembly line, and then manually untie the ropes. This greatly increases the labor cost, and the overall loading process is time-consuming and inefficient. It is also impossible to adapt to battery pack coils of different sizes and adjust their spacing. Utility Model Content

[0024] Example:

[0025] Reference Figure 1-4 A spacing adjustment mechanism for a coil material grabbing device comprises a battery pack grabbing device 1, an aluminum load-bearing plate 2 is arranged at the bottom of the battery pack grabbing device 1, two cylinder fixed aluminum blocks 3 are symmetrically arranged on the top side of the aluminum load-bearing plate 2, one side of the cylinder fixed aluminum block 3 is fixedly connected to an electric cylinder 1 301, an output end of the electric cylinder 1 301 is connected to a cylinder joint 302, and one end of the cylinder joint 302 is fixedly connected to a cylinder fixed block 303;

[0026] Two groups of anti-movement plates 304 are symmetrically arranged on both sides of the aluminum load-bearing plate 2. Each group of anti-movement plates 304 are connected and fixed by claw side plates 6. The sides of the anti-movement plates 304 are fixedly connected to the cylinder fixing blocks 303. The claw side plates 6 and the sides of the anti-movement plates 304 are provided with installation grooves, and the load-bearing blocks 305 are fixedly connected in the installation grooves.

[0027] Two groups of organ mounting plates 5 are symmetrically arranged on the aluminum load-bearing plate 2 . A guide rail organ cover 501 is fixedly connected to one end of the organ mounting plate 5 . A guide rail bar 502 is fixedly connected to the side of the guide rail organ cover 501 away from the organ mounting plate 5 .

[0028] The guide rail 502 is slidably connected to a slider 503 , and the top of the slider 503 is fixedly connected to a load-bearing block 305 , and one side of the load-bearing block 305 is fixedly connected to the claw side plate 6 .

[0029] A cylinder fixing plate 4 is fixedly connected between the two anti-motion plates 304, and an electric cylinder 2 41 is arranged at the top center of the cylinder fixing plate 4. The output end of the electric cylinder 2 41 is connected to a rod 401, and the connecting rod 401 penetrates the cylinder fixing plate 4 and extends to the bottom of the cylinder fixing plate 4 and is connected to a connecting block 402. Two groups of connecting rod pieces 403 are symmetrically arranged at both ends of the connecting block 402, and the two groups of connecting rod pieces 403 are connected to each other by an axle pin 404. Each group of connecting rod pieces 403 is connected to a claw 7 through a cylindrical pin, and a half hole is opened at the bottom of the claw 7, and copper-aluminum foil coils 8 are arranged in the two half holes.

[0030] The outer walls of the aluminum load-bearing plate 2 and the anti-movement plate 304 are both provided with positioning holes, and double steel ball pins 307 are arranged in the positioning holes.

[0031] An aluminum pad 306 is fixedly connected to the side of the load-bearing block 305 , and a movable hole for the guide rail 502 to pass through is opened at the bottom of the aluminum pad 306 .

[0032] In this embodiment, when it is necessary to grab and move battery pack coils of different sizes, first remove the double steel ball pin 307 from the positioning hole to free the anti-movement plate 304 from the restriction between the aluminum load-bearing plate 2, and then insert the copper-aluminum foil coil 8 at one end into the half hole of the claw 7. At this time, start the electric cylinder 2 41. When the electric cylinder 2 41 is running, it drives the connecting rod 401 to move upward. The upward movement of the connecting rod 401 drives the connecting block 402 to move upward, so that the connecting rod pieces 403 on both sides move downward with the axle pin 404 as the fulcrum, thereby closing the two half holes to form a circular hole, so that one end of the copper-aluminum foil coil 8 can be tightly fixed in the claw 7.

[0033] Furthermore, when the spacing between the claws 7 needs to be adjusted, the electric cylinder 301 is started at the same time. When the electric cylinder 301 is running, it pushes the cylinder joint 302. When the cylinder joint 302 moves, it drives the cylinder fixing block 303 and the anti-movement plate 304 to move. When the anti-movement plate 304 moves, it drives the load-bearing block 305 and the cylinder fixing plate 4 to slide along the track of the guide rail 502 in turn. Therefore, when the cylinder fixing plate 4 moves, it drives the connecting rod 401 and the connecting block 402 to move. When the connecting block 402 moves, it drives the connecting rod piece 403 to move. The connecting rod piece 403 moves. When the battery pack is moved, the claws 7 on the same side are driven to move, so that when the claws 7 on both sides move toward each other, a suitable spacing can be selected according to the size and width of the battery pack coil, until the two claws 7 on the same side are engaged and fixed at the other end of the battery pack coil, and then the copper-aluminum foil coil 8 can be fixed between the claws 7, and then the double steel ball pin 307 is inserted into the corresponding positioning hole of the aluminum bearing plate 2 through the positioning hole of the anti-movement plate 304 again, and the anti-movement plate 304 and the aluminum bearing plate 2 are fixed to each other to prevent the claws 7 from shaking and loosening during the grabbing and moving process of the copper-aluminum foil coil 8.
