Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle battery disassembly, specifically relating to a new energy vehicle battery pack disassembly device. Background Technology

[0002] With the development of science and technology and people's lives, new energy vehicles are becoming increasingly popular, and the number of new energy vehicles reaching their service life is also gradually increasing. New energy vehicles that have reached their service life are generally dismantled and recycled. One of the most important components of a new energy vehicle is the battery pack, which is also a crucial part of dismantling and recycling. Generally, a new energy vehicle's battery pack includes a casing, a cover, and battery cells. The battery cells are placed inside the casing, and the cover is fixed to the opening of the casing. Sealant is applied at the contact point between the casing and the cover to completely seal the battery cells within the casing.

[0003] When disassembling the battery pack of a new energy vehicle, the operator first removes the screws between the box and the cover. Then, tools are used to separate the cover from the box. Since the contact area between the box and the cover is sealed with sealant, the operator needs to use tools to pry the cover off. This process is not only physically demanding but also poses certain safety hazards. If the operator accidentally punctures the battery cell, it can easily cause explosions, fires, and other hazards. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new energy vehicle battery pack disassembly equipment, which can not only reduce the labor intensity of workers, but also avoid damaging the battery cells, thereby further improving the safety of the battery pack disassembly process.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A new energy vehicle battery pack disassembly device, comprising:

[0007] The base has a worktable slidably connected to its upper surface. A first slide groove is provided on the worktable. A first bidirectional lead screw is rotatably connected in the first slide groove. A first slider is threaded onto each of the two threads of the first bidirectional lead screw with different helix directions. The first slider is slidably connected in the first slide groove. A clamping plate is fixedly connected to the top of the first slider.

[0008] A gantry frame is fixedly connected to the upper surface of a base. Second sliding grooves are provided on the side arms of the gantry frame. A telescopic cylinder is fixedly connected to the crossbeam of the gantry frame. A lifting plate is fixedly connected to the piston end of the telescopic cylinder through the crossbeam of the gantry frame. Both ends of the lifting plate are slidably connected within the second sliding grooves. Fixed rods are fixedly connected to the lower surfaces of both ends of the lifting plate. A second slider is fixedly connected to the bottom end of the fixed rod. The second slider is slidably connected within the second sliding groove. A rotating shaft is rotatably connected to the second slider. A bracket is fixedly connected to the inner end of the rotating shaft. A second double-acting screw is rotatably connected to the inner side of the bracket. Two clamping plates are provided between the two brackets. The same end of the two clamping plates is threaded onto threads of different directions of the second double-acting screw. A third sliding groove is provided on one of the clamping plates, and at least one pin is slidably connected within the third sliding groove. An clearance groove is provided on the other clamping plate.

[0009] The principles and technical effects of the above technical solution are as follows:

[0010] The battery pack of the new energy vehicle is placed on the workbench. By driving the first bidirectional screw to rotate, the two clamping plates move towards each other to clamp the battery pack and fix it in place. At the same time, the end of the battery pack cover near the gantry is pre-tilted up, and then a hole is drilled. The piston rod at the upper end of the telescopic cylinder extends, causing the two clamping plates to move down and approach the battery pack cover. The pre-tilted part of the battery pack cover is inserted into the two clamping plates, and the pin is moved to insert into the hole of the pre-tilted part of the battery pack cover. By simultaneously rotating the second bidirectional screw, the two clamping plates move towards each other to clamp the pre-tilted part of the battery pack cover. At this time, the pin is inserted into the clearance groove to prevent the pre-tilted part of the battery pack cover from detaching. By driving one of the rotating shafts to rotate, the two clamping plates rotate around the shaft. During this process, the battery pack cover is peeled off and wound around the two clamping plates. At the same time, during the peeling process, the workbench will cause the battery pack to slide on the base, so that the peeled-off position of the cover is below the clamping plates.

[0011] In a preferred embodiment, the present invention can be further configured as follows: baffles are fixedly connected to both ends of the base, a plurality of guide rods are fixedly connected between the two baffles, and sliding sleeves are slidably connected to the guide rods, and the sliding sleeves are fixedly connected to the lower surface of the worktable.

[0012] In a preferred embodiment, the present invention can be further configured such that: a fourth slide groove is provided on both sides of the first slide groove on the worktable, a slide rod is fixedly connected in the fourth slide groove, a third slider is slidably connected on the slide rod, and the third slider is fixedly connected to the lower end of the clamping plate.

[0013] In a preferred embodiment, the present invention can be further configured such that a first drive unit is fixedly connected to one end of the first bidirectional lead screw.

[0014] In a preferred embodiment, the present invention can be further configured such that a motor is fixedly connected to one of the second sliders, and the output end of the motor is fixedly connected to the rotating shaft.

[0015] In a preferred embodiment, the present invention can be further configured such that a second drive unit is fixedly connected to one end of the second bidirectional lead screw.

[0016] In a preferred embodiment, the present invention can be further configured such that the distance between the side arms on both sides of the gantry is greater than the width of the worktable.

[0017] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0018] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0019] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0020] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly is required by forging, sawing, or oxy-acetylene cutting during repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.) when making connections.

[0021] A threaded connection is a detachable connection in which threaded parts (or the threaded portion of the connected parts) are joined together as one unit.

[0022] A sliding connection refers to two objects that are in contact but not fixed, and can slide relative to each other.

[0023] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0024] The beneficial effects of this utility model are:

[0025] The battery pack of the new energy vehicle is placed on the workbench. By driving the first bidirectional screw to rotate, the two clamping plates move towards each other to clamp the battery pack and fix it in place. At the same time, the end of the battery pack cover near the gantry is pre-tilted up, and then a hole is drilled. The piston rod at the upper end of the telescopic cylinder extends, causing the two clamping plates to move down and approach the battery pack cover. The pre-tilted part of the battery pack cover is inserted into the two clamping plates, and the pin is moved to insert into the hole of the pre-tilted part of the battery pack cover. By simultaneously rotating the second bidirectional screw, the two clamping plates move towards each other to clamp the pre-tilted part of the battery pack cover. At this time, the pin is inserted into the clearance groove to prevent the pre-tilted part of the battery pack cover from detaching. By driving one of the rotating shafts to rotate, the two clamping plates rotate around the shaft. During this process, the battery pack cover is peeled off and wound around the two clamping plates. At the same time, during the peeling process, the workbench will cause the battery pack to slide on the base, so that the peeled-off position of the cover is below the clamping plates. This method not only reduces the labor intensity of workers but also minimizes damage to the battery cells, further enhancing the safety of the battery pack disassembly process.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] Based on the concept of this application, combined with Figures 1 to 4 This describes an embodiment of a new energy vehicle battery pack disassembly device. Specifically, the new energy vehicle battery pack disassembly device is constructed as a split structure, comprising a base 1, a worktable 2, a gantry frame 7, and other components. The battery pack of the new energy vehicle is placed on the worktable 2. By driving the first bidirectional lead screw 4 to rotate, two clamping plates 6 move towards each other to clamp the battery pack, thus fixing it in place. Simultaneously, the end of the battery pack cover near the gantry frame 7 is pre-tilted up, and then a hole is drilled. The piston rod at the upper end of the telescopic cylinder 9 extends, causing the two clamping plates 16 to move down towards the battery pack cover. The pre-tilted portion of the battery pack cover is inserted into the two clamping plates 16, and the pin 18 is moved to insert into the hole in the pre-tilted portion of the battery pack cover. Simultaneously, the device rotates... The second bidirectional lead screw 15 is moved so that the two clamping plates 16 move towards each other to clamp the pre-raised part of the battery pack cover. At this time, the pin 18 is inserted into the clearance groove 19 to prevent the pre-raised part of the battery pack cover from coming off. By driving one of the rotating shafts 13 to rotate, the two clamping plates 16 are driven to rotate around the rotating shaft 13. During this process, the battery pack cover will be peeled off and wound around the two clamping plates 16. At the same time, during the peeling process, the worktable 2 will drive the battery pack to slide on the base 1 so that the peeled position of the cover is below the clamping plate 16.

[0034] like Figures 1 to 4 As shown, a new energy vehicle battery pack disassembly device includes:

[0035] A base 1 is slidably connected to a worktable 2 on its upper end face. A first slide groove 3 is provided on the worktable 2. A first bidirectional lead screw 4 is rotatably connected in the first slide groove 3. A first slider 5 is threadedly connected to the two threads of the first bidirectional lead screw 4 with different directions of rotation. The first slider 5 is slidably connected in the first slide groove 3. A clamping plate 6 is fixedly connected to the top of the first slider 5.

[0036] A gantry frame 7 is fixedly connected to the upper surface of the base 1. Second sliding grooves 8 are provided on the side arms of the gantry frame 7. Telescopic cylinders 9 are fixedly connected to the crossbeam of the gantry frame 7. A lifting plate 10 is fixedly connected to the piston end of the telescopic cylinder 9 through the crossbeam of the gantry frame 7. Both ends of the lifting plate 10 are slidably connected within the second sliding grooves 8. Fixed rods 11 are fixedly connected to the lower surfaces of both ends of the lifting plate 10. A second slider 12 is fixedly connected to the bottom end of the fixed rods 11 and slidably connected to the second sliding grooves 8. Inside, a rotating shaft 13 is rotatably connected to the second slider 12. A bracket 14 is fixedly connected to the inner end of the rotating shaft 13. A second bidirectional lead screw 15 is rotatably connected to the inner side of the bracket 14. Two clamping plates 16 are arranged between the two brackets 14. The same end of the two clamping plates 16 is threaded to the threads of the second bidirectional lead screw 15 in different directions. A third sliding groove 17 is provided on one of the clamping plates 16. At least one pin 18 is slidably connected in the third sliding groove 17. An avoidance groove 19 is provided on the other clamping plate 16.

[0037] In use, the battery pack of the new energy vehicle is placed on the workbench 2. The first bidirectional lead screw 4 is driven to rotate, causing the two clamping plates 6 to move towards each other and clamp the battery pack, thus fixing it in place. Simultaneously, the end of the battery pack cover near the gantry 7 is pre-tilted up, and then a hole is drilled. The piston rod at the upper end of the telescopic cylinder 9 extends, causing the two clamping plates 16 to move down towards the battery pack cover. The pre-tilted portion of the battery pack cover is inserted into the two clamping plates 16, and the pin 18 is moved to insert into the hole in the pre-tilted portion of the battery pack cover. This process is repeated. When the second bidirectional lead screw 15 is rotated, the two clamping plates 16 move towards each other to clamp the pre-raised part of the battery pack cover. At this time, the pin 18 is inserted into the clearance groove 19 to prevent the pre-raised part of the battery pack cover from coming off. By driving one of the rotating shafts 13 to rotate, the two clamping plates 16 are driven to rotate around the rotating shaft 13. During this process, the battery pack cover will be peeled off and wound around the two clamping plates 16. At the same time, during the peeling process, the worktable 2 will drive the battery pack to slide on the base 1, so that the peeled position of the cover is below the clamping plate 16.
