Description

Technical Field

[0001] The invention relates to the technical field of automobile battery pack disassembly robots, in particular to a scrap automobile recycling and disassembly device. Background Art

[0002] When new energy vehicles that use electricity as a power source reach their service life or are scrapped due to quality problems, they need to be scrapped and recycled, and the battery pack of new energy vehicles needs to be disassembled and recycled separately. The battery pack of new energy vehicles consists of a battery module and an outer protective shell. The outer protective shell protects the battery module inside, and the outer protective shell is fixed together by a large number of screws. When disassembling and recycling the battery pack, the screws on the surface of the outer protective shell need to be removed.

[0003] There are two ways to remove the screws on the surface of the protective shell outside the battery pack, one is manual disassembly, and the other is robot disassembly. The efficiency of robot disassembly is faster than manual disassembly, but the existing disassembly robot usually has only one screw disassembly head and can only remove one screw at a time. When multiple disassembly heads are used, multiple drive motors are required to control each disassembly head separately to realize independent operation of the disassembly head. Since there are many screws on the surface of the protective shell outside the battery pack, the disassembly efficiency of traditional disassembly robots still needs to be improved. Summary of the invention

[0004] In order to solve the problem that the conventional disassembly robot has a multi-screw disassembly head design, multiple drive motors are required to individually control each disassembly head to realize independent operation of the disassembly head, and the disassembly efficiency of the conventional disassembly robot is low, the present invention is achieved through the following technical solutions: a scrap car recycling and disassembly device, comprising a disassembly robot, the disassembly robot comprising a drive box and a disassembly hand, a plurality of the disassembly hands are distributed at the bottom of the drive box, and the disassembly hands can slide along the width direction of the drive box;

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The embodiment of the scrapped car recycling and disassembly device is as follows:

[0039] See also Figure 1-Figure 11 A scrap car recycling and disassembly device includes a disassembly robot, which consists of a drive box 1 and a disassembly hand. A plurality of disassembly hands are distributed at the bottom of the drive box 1. The disassembly hand can slide along the width direction of the drive box 1 to place a battery pack to be disassembled below the drive box 1. According to the position of the screws on the surface of the battery pack, the position of the disassembly hand is adjusted so that the disassembly hand corresponds to the screws to be disassembled up and down. A screw disassembly rod 21 is installed at the lower end of the disassembly hand. The working opening at the lower end of the screw disassembly rod 21 is adapted to the screw. The screws on the surface of the battery pack can be disassembled by rotating the screw disassembly rod 21. The screws on the surface of the battery pack can also be tightened and installed by adjusting the rotation direction of the screw disassembly rod 21.

[0040] The disassembly hand includes a mounting seat 2, a rotating rod 3, and a sliding seat 6. A screw disassembly rod 21 is installed on the lower surface of the mounting seat 2. A buffer rod 4 is fixedly installed on the upper surface of the mounting seat 2. A free telescopic rod 5 is axially slidingly sleeved on the upper end of the buffer rod 4. A buffer spring is provided between the buffer rod 4 and the free telescopic rod 5. When the screw is removed by using the screw disassembly rod 21, the buffer rod 4 moves toward the inside of the free telescopic rod 5 for buffering, so as to remove the screw from the threaded hole. At this time, the free telescopic rod 5 and the rotating rod 3 are in a relatively fixed state.

[0041] Two arc-shaped clamping blocks 61 are slidably disposed inside the slide seat 6 . The two clamping blocks 61 are distributed on both sides of the upper end of the rotating rod 3 , and the two clamping blocks 61 are adapted to the rotating rod 3 .

[0042] The clamping block 61 is fixedly installed with a top block 62 through a connecting rod. The top block 62 can extend out of the outside of the slide seat 6. The inner wall of the guide groove 10 is provided with a limiting slide groove 101. When the top block 62 extends out of the outside of the slide seat 6, it enters the limiting slide groove 101 and is in friction contact with the limiting slide groove 101. The contact surfaces of the top block 62 and the limiting slide groove 101 are both designed with a tooth groove structure, which is used to increase the limiting resistance of the top block 62 to the slide seat 6 when it contacts the limiting slide groove 101.

[0043] When the clamping block 61 is in frictional contact with the rotating rod 3, the rotating rod 3 and the slide seat 6 are relatively fixed. At this time, the top block 62 is not in contact with the limiting slide groove 101. When the top block 62 is in frictional contact with the limiting slide groove 101, the slide seat 6 and the guide groove 10 are relatively fixed, and the rotating rod 3 and the slide seat 6 rotate relatively.

[0044] An adjusting rod 7 is axially slidably installed inside the rotating rod 3. The adjusting rod 7 is controlled and driven by an electromagnetic driving block 71. The electromagnetic driving block 71 is composed of an electromagnetic block fixedly installed inside the rotating rod 3 and fixedly installed on the surface of the adjusting rod 7. The electromagnetic block is connected to a power supply, and the interaction force between the two groups of electromagnetic blocks is utilized to control the movement of the adjusting rod 7. A cavity is opened at the top inside the sliding seat 6, and the upper end of the adjusting rod 7 can extend into the cavity.

[0045] A wedge block 63 is fixedly installed on the surface of the connecting rod between the clamping block 61 and the top block 62, a return spring is provided between the wedge block 63 and the inner wall of the slide seat 6, a rocker 8 is rotatably installed inside the cavity, a return spring is provided between the rocker 8 and the inner top wall of the cavity, one end of the rocker 8 corresponds to the upper end of the adjusting rod 7, and a connecting rod 81 is rotatably installed on the other end, and a spherical block 82 is rotatably installed on the other end of the connecting rod 81, and the spherical block 82 is located between the inclined surface of the wedge block 63 and the inner wall of the cavity.

[0046] When the adjusting rod 7 moves upward, the adjusting rod 7 pushes the rocker 8 to rotate, the rocker 8 pushes the spherical block 82 to move through the connecting rod 81, the spherical block 82 pushes the wedge block 63 to move, and the wedge block 63 drives the clamping block 61 and the top block 62 to move synchronously through the connecting rod, so that the position of the clamping block 61 and the top block 62 can be adjusted by using the movement of the adjusting rod 7.

[0047] The upper end of the free telescopic rod 5 is axially slidably sleeved on the lower end of the rotating rod 3, and the lower end of the adjusting rod 7 corresponds to the upper end of the free telescopic rod 5. The free telescopic rod 5 in the unused disassembly hand and the lower end of the rotating rod 3 are in a relative sliding state. When the screw disassembly rod 21 corresponding to the disassembly hand contacts the surface of the battery pack, no squeezing force is generated on the surface of the battery pack. The free telescopic rod 5 corresponding to the disassembly hand that needs to be used and the rotating rod 3 are in a relatively fixed state.

[0048] A transmission gear 31 is fixedly installed on the surface of the rotating rod 3, the slide 6 is located at the upper end of the rotating rod 3, and the upper end of the rotating rod 3 extends to the inside of the slide 6. A guide groove 10 is fixedly installed on the top wall inside the driving box 1. The arrangement direction of the guide groove 10 is the same as the movement and adjustment direction of the disassembly hand, and the slide 6 is set in the guide groove 10.

[0049] A driving mechanism for adjusting the position of the disassembly hand and driving the screw disassembly rod 21 to rotate is provided inside the driving box 1. The driving mechanism is used to adjust the position of one or more required disassembly hands, and drive the screw disassembly rod 21 at the lower end of the one or more disassembly hands to rotate. The screws on the surface of the battery pack shell are removed by rotating the screw disassembly rod 21.

[0050] The driving mechanism includes several groups of driving modules consisting of a main pulley 9 , a slave pulley 91 and a toothed belt 92 , and also includes a transmission shaft 13 and several groups of worm gear assemblies 14 .

[0051] The transmission shaft 13 is driven to rotate by a motor installed on the side surface of the drive box 1. The worms in several groups of worm gear assemblies 14 are all installed on the surface of the transmission shaft 13. A friction plate 141 that can move radially is provided inside the worm. An electric-driven telescopic rod is provided between the friction plate 141 and the inner wall of the worm. The position of the friction plate 141 is controlled and adjusted by connecting the electric-driven telescopic rod to a power source. The positional relationship between the friction plate 141 and the transmission shaft 13 is used to control the relative fixation or relative rotation of the worm and the transmission shaft 13.

[0052] A plurality of worm gear assemblies 14 correspond to a plurality of drive modules. When the worm gear in the worm gear assemblies 14 rotates, the corresponding main pulley 9 is driven to rotate.

[0053] A direction-changing mechanism 11 is provided between the worm gear assembly 14 and the main pulley 9. The direction-changing mechanism 11 includes a bevel gear disc 1 111, a bevel gear disc 2 112 and a bevel gear 113. The bevel gear disc 1 111 and the bevel gear disc 2 112 are relatively distributed. The bevel gear 113 is rotatably installed on the inner wall of the drive box 1. The bevel gear 113 is meshed with the bevel gear disc 1 111 and the bevel gear disc 2 112 at the same time.

[0054] An input shaft 12 is fixedly installed at the lower end of the worm gear, a bevel gear disc 111 is rotatably installed on the surface of the input shaft 12, a connecting shaft 114 is coaxially rotatably installed between the bevel gear disc 111 and the bevel gear disc 2 112, the connecting shaft 114 is fixedly connected to the input shaft 12, and the bevel gear disc 2 112 is fixedly connected to the main pulley 9.

[0055] Limiting rings 115 are fixedly installed on the surfaces corresponding to the connecting shaft 114 and the bevel gear disc 111 and the bevel gear disc 2 112, and limiting holes are provided on the surfaces of the limiting rings 115. Mounting blocks 116 are fixedly installed on the surfaces of the bevel gear disc 111 and the bevel gear disc 2 112, and limiting rods 117 are slidably installed inside the mounting blocks 116. An electromagnetic driving block 71 for driving the limiting rod 117 to move is installed inside the mounting blocks 116. The electromagnetic driving block 71 inside the mounting blocks 116 is used to control the movement of the limiting rod 117, thereby controlling the positional relationship between the limiting rod 117 and the limiting holes on the surfaces of the corresponding limiting rings 115, and the limiting rod 117 can cooperate with the limiting holes on the surfaces of the corresponding limiting rings 115.

[0056] While ensuring that the rotation direction of the worm gear remains unchanged, the rotation direction of the main pulley 9 is adjusted by using the changing mechanism 11. The main pulley 9 cooperates with the slave pulley 91 to drive the toothed belt 92 to move. Several groups of driving modules correspond one by one to several disassembly hands, and the transmission gear 31 engages with the corresponding toothed belt 92.

[0057] There are two connection states between the rotating rod 3 and the slide 6: relatively fixed and relatively rotating. When the rotating rod 3 and the slide 6 are relatively fixed, the slide 6 can slide inside the guide groove 10. At this time, the engagement of the toothed belt 92 and the transmission gear 31 is used to adjust the position of the disassembly hand. When the rotating rod 3 and the slide 6 rotate relatively, the slide 6 and the guide groove 10 are relatively fixed. At this time, the engagement of the toothed belt 92 and the transmission gear 31 is used to drive the rotating rod 3 to rotate, and the rotation of the rotating rod 3 drives the screw disassembly rod 21 to rotate synchronously.

[0058] By providing the direction-changing mechanism 11 and cooperating with the rotating rod 3 and the sliding seat 6 , the driving mechanism can be used to realize independent position and direction adjustment of multiple disassembly hands and drive and rotate the screw disassembly rod 21 .

[0059] Working principle of scrap car recycling and dismantling device:

[0060] The battery pack of the scrapped car is placed under the drive box 1 in the disassembly robot. Image recognition technology (this technology adopts existing technology) can be added to identify the position of the screws in the battery pack, and then the image information of the position of the identified screws is fed back to the drive system, and the drive system is used to control the drive to adjust the position of the disassembly hand (this drive system can be implemented using existing technology).

[0061] The motor can be used to drive the transmission shaft 13 to rotate. When one or more disassembly hands are needed, the friction plate 141 inside the corresponding worm is controlled to make friction contact with the surface of the transmission shaft 13. The rotation of the transmission shaft 13 drives the corresponding worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the input shaft 12 to rotate, and the input shaft 12 drives the main pulley 9 to rotate through the changing mechanism 11. The main pulley 9 cooperates with the slave pulley 91 to drive the toothed belt 92 to move.

[0062] The electromagnetic drive block 71 is used to control the adjustment rod 7 to move upward or downward. When the adjustment rod 7 moves upward, the clamping block 61 will clamp the upper end of the rotating rod 3, and the top block 62 will separate from the limiting slide groove 101. At this time, the rotating rod 3 and the slide seat 6 are relatively fixed, and the slide seat 6 and the guide groove 10 slide relatively. At this time, the toothed belt 92 is engaged with the transmission gear 31, and the transmission gear 31 does not rotate. The toothed belt 92 will drive the transmission gear 31 to move, so that the position of the disassembly hand can be adjusted.

[0063] When the adjusting rod 7 moves downward, the clamping block 61 will separate from the rotating rod 3, and the top block 62 will frictionally contact with the limiting slide groove 101. At this time, the rotating rod 3 and the slide seat 6 will rotate relative to each other, and the slide seat 6 and the guide groove 10 will be relatively fixed. At this time, the toothed belt 92 will mesh with the transmission gear 31, and the transmission gear 31 will rotate synchronously. The transmission gear 31 will drive the screw removal rod 21 to rotate together through the rotating rod 3, so that the screws on the surface of the battery pack can be removed or installed.

[0064] When the limiting rod 117 in the mounting block 116 on the surface of the bevel gear disc 111 in the changing mechanism 11 is in a separated state from the corresponding limiting hole, and at the same time, the limiting rod 117 in the mounting block 116 on the surface of the bevel gear disc 112 is in a matched state with the corresponding limiting hole, the rotation of the input shaft 12 at this time will directly drive the bevel gear disc 112 to rotate through the connecting shaft 114, and the bevel gear disc 112 drives the main pulley 9 to rotate. At this time, the rotation direction of the main pulley 9 is the same as that of the input shaft 12.

[0065] When the limiting rod 117 corresponding to the bevel gear disc 111 is in a matched state with the corresponding limiting hole, and the limiting rod 117 corresponding to the bevel gear disc 112 is in a separated state with the corresponding limiting hole, the rotation of the input shaft 12 will directly drive the bevel gear disc 111 to rotate through the connecting shaft 114, the bevel gear disc 111 drives the bevel gear disc 112 to rotate by meshing with the bevel gear 113, and the bevel gear disc 112 drives the main pulley 9 to rotate. At this time, the rotation directions of the main pulley 9 and the input shaft 12 are opposite.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
