DETAILED DESCRIPTION

[0030] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] Embodiment 1: A lithium iron phosphate battery disassembly and recycling device, such as Figure 1-9As shown, it includes a workbench 1, the front side of the workbench 1 is connected to a plurality of equally spaced shaft rollers 2 for rotation from left to right, the middle of the workbench 1 is connected to an equally spaced shaft roller 2 for rotation from front to back, the top of the workbench 1 is connected to a slide 3 for sliding along the front and rear directions, the bottom of the slide 3 is connected to a pulley 4 symmetrically distributed along the left and right sides of the slide 3 for rotation, and also includes two force-bearing frames 5, one of which slides left and right on the slide 3, and the other force-bearing frame 5 is fixed to the top right side of the front side of the workbench 1, a first electric push rod 6 is fixed to the force-bearing frame 5, the moving part of the first electric push rod 6 is fixed to a pressing frame 7, a moving rod 8 is arranged on the pressing frame 7, the moving rod 8 is connected to the adjacent force-bearing frame 5 for sliding, a scraper 9 is arranged on the moving rod 8, three equally spaced baffles 13 are fixed to the front side of the workbench 1, the baffles 13 are arranged in an inverted T shape, and the lithium iron phosphate battery 101 moves forward and contacts the baffles 13, The rear side of the retaining frame 13 is slidably connected with a positioning rod 14 in the up and down directions. When the first spring 10 is in a natural state, the top of the positioning rod 14 protrudes from the front shaft roller 2. The top of the positioning rod 14 is set as a wedge-shaped surface. The lithium iron phosphate battery 101 moves forward and contacts the wedge-shaped surface of the positioning rod 14. The distance between the retaining frame 13 and the adjacent positioning rod 14 is equal to the height of the lithium iron phosphate battery 101. The retaining frame 13 and the positioning rod 14 jointly limit the flipped battery bar. The first spring 10 is fixedly connected between the retaining frame 13 and the adjacent positioning rod 14. The second electric push rod 11 symmetrically distributed along the left and right sides of the workbench 1 is fixedly connected to the lower front side of the workbench 1. The top frame 12 is fixedly connected between the telescopic parts of the second electric push rod 11. The top frame 12 is located on the rear side of the battery bar. The top frame 12 passes upward through the gap between the adjacent shaft rollers 2 on the front side, thereby contacting the front side of the bottom rear side of the battery bar and flipping the battery bar forward.

[0032] When removing glue and disassembling the lithium iron phosphate battery 101, first, move a whole lithium iron phosphate battery 101 forward from the back to the front axis roller 2. During this process, the lithium iron phosphate battery 101 contacts the wedge-shaped surface at the top of the positioning rod 14, and squeezes the positioning rod 14 to slide downward relative to the retaining frame 13. The first spring 10 is compressed until the front side of the lithium iron phosphate battery 101 contacts the retaining frame 13, and the top of the positioning rod 14 contacts the bottom of the lithium iron phosphate battery 101. At this time, the transverse dividing glue line on the front side of the lithium iron phosphate battery 101 is located directly below the scraper 9 on the non-fixed force frame 5. Then the first electric push rod 6 on the slide 3 is controlled to shorten downward, thereby driving the pressing frame 7 on it to move downward. The pressing frame 7 drives the scraper 9 to move downward through the moving rod 8. The scraper 9 passes downward through the transverse dividing glue line of the lithium iron phosphate battery 101, and then the non-fixed force frame 5 is controlled to slide left and right along the slide 3, so that the scraper 9 removes glue and disassembles the lithium iron phosphate battery 101 in strips along the transverse dividing glue line.

[0033] After completing the above-mentioned strip-shaped glue removal and disassembly, it is also necessary to remove the glue from the bottom surface of the battery strip. Therefore, it is necessary to flip the bottom surface of the battery strip to the rear part for easy operation of the scraper 9. The specific flipping operation is as follows: control the second electric push rod 11 to extend upward, and push the top frame 12 to move upward. Since the top frame 12 is located at the rear side of the bottom of the battery strip, the front side of the battery strip is limited by the blocking frame 13, and the top frame 12 moves upward to make the bottom surface of the battery strip flip from the bottom to the rear. In the flipping process, as the bottom surface of the battery strip gradually flips to disengage from the positioning rod 14, the first spring 10 in a compressed state gradually resets, and finally the flipped battery strip is limited between the blocking frame 13 and the positioning rod 14. After that, push the slide 3 forward so that the scraper 9 on it moves forward to contact the bottom surface of the battery strip flipped to the rear. In this way, the glue on the bottom surface of the battery strip can be easily removed.

[0034] After the glue removal on the bottom is completed, the battery strip is pushed from left to right along the shaft roller 2 to move the broken battery strip to the right. When the longitudinal glue dividing line on the rightmost side of the battery strip moves to just below the scraper 9 on the fixed force-bearing frame 5, the first electric push rod 6 on the fixed force-bearing frame 5 is controlled to shorten downward, thereby driving the pressing frame 7 on it to move downward. The pressing frame 7 drives the scraper 9 to move downward through the moving rod 8. The scraper 9 passes downward through the longitudinal glue dividing line of the battery strip, thereby debonding and disassembling the battery strip in blocks along the longitudinal glue dividing line. Repeating this process can remove the glue from a whole lithium iron phosphate battery 101 and disassemble it into several identical battery blocks. The battery blocks after debonding can be crushed in the next step.

[0035] Embodiment 2: On the basis of Embodiment 1, it further includes a bracket 15, which is slidably connected to the moving rod 8, and the moving rod 8 is rotatably connected to the adjacent scraper 9. Two limit blocks 16 are fixedly connected to the moving rod 8, and the limit blocks 16 are slidably connected to the adjacent bracket 15. The top of the bracket 15 is in contact with the adjacent force-bearing frame 5, and a tension spring 17 is fixedly connected between the limit blocks 16 and the adjacent bracket 15. The bracket 15 moves downward and disengages from the adjacent force-bearing frame 5. At this time, the tension spring 17 resets and drives the bracket 15 to slide upward and insert into the adjacent moving rod 8.

[0036] Each time the scraper 9 passes through the splitting glue line of the lithium iron phosphate battery 101 downward, the battery is divided into two parts. The following is an example of the scraper 9 passing through the horizontal splitting glue line of the battery downward: If the scraper 9 is set vertically, it is difficult to effectively remove the glue from the rear side of the front part of the battery and the front side of the rear part of the battery. Therefore, the scraper 9 is set to be inclined forward and downward, so that the scraper 9 can effectively scrape the glue from the rear side of the front part of the battery at the beginning. When it is necessary to effectively scrape off the adhesive on the front side of the rear part of the battery, when the moving rod 8 moves upward, the bracket 15 and the limit block 16 move upward synchronously with the moving rod 8. When the top of the bracket 15 contacts the adjacent force-bearing frame 5, the bracket 15 no longer moves upward, and the moving rod 8 still drives the limit block 16 and the scraper 9 to continue to move upward. The tension spring 17 is stretched, so that the scraper 9 is upwardly separated from the bracket 15, so that the bracket 15 no longer fixes the scraper 9 on the adjacent moving rod 8. At this time, the scraper 9 can be Rotate one hundred and eighty degrees to make the scraper 9 tilt toward the lower rear. When the moving rod 8 drives the scraper 9, the bracket 15, the limit block 16 and the tension spring 17 to move downward, the top of the bracket 15 is separated from the adjacent force-bearing frame 5, and the tension spring 17 is reset to drive the bracket 15 to move upward relative to the moving rod 8 until it is inserted into the scraper 9, thereby fixing the scraper 9 on the adjacent moving rod 8 to prevent the scraper 9 from rotating at will when scraping glue. The scraper 9 that is switched to tilt toward the lower rear and fixed can effectively scrape off the glue on the front side of the rear part of the battery.

[0037] Embodiment 3: On the basis of Embodiment 2, it further includes two sliders 18, which are slidably connected to the adjacent pressure frame 7, and a screw 19 is threadedly connected to the side of the pressure frame 7 away from the adjacent moving rod 8, the slider 18 is rotatably connected to the adjacent screw 19, a second spring 20 is fixed to the slider 18, and a pressure block 21 is slidably connected to the pressure frame 7, the pressure block 21 is fixed to the adjacent second spring 20, the moving rod 8 is slidably connected to the adjacent pressure frame 7, and a side of the pressure block 21 close to the adjacent moving rod 8 is set as a wedge-shaped surface, and the pressure block 21 contacts the adjacent moving rod 8 through the wedge-shaped surface, and the pressure block 21 presses the moving rod 8 when the scraper 9 is aligned with the dividing rubber line of the battery, and the pressure block 21 relieves the moving rod 8 when the scraper 9 is not aligned with the dividing rubber line of the battery.

[0038] Under normal circumstances (the scraper 9 is aligned with the dividing glue line of the battery), by rotating the screw 19, the screw 19 pushes and pulls the pressure block 21 through the slider 18 and the second spring 20 to move, so as to adjust the degree of pressure of the pressure block 21 on the adjacent moving rod 8 according to the ease of scraping the adhesive. When scraping the adhesive, the pressure frame 7 drives the slider 18, the screw 19, the second spring 20, the pressure block 21, the moving rod 8 and the scraper 9 to descend as a whole, and normal scraping of the adhesive can be carried out.

[0039] If an abnormal situation occurs (the scraper 9 is not aligned with the dividing glue line of the battery), the scraper 9 will directly act on the top surface of the battery entity. At this time, the scraper 9 is directly forced downward by the first electric push rod 6, which will damage the battery and the scraper 9. Therefore, in this case, the moving rod 8 is released in time, thereby releasing the force of the scraper 9 in time to protect the battery and the scraper 9. The specific release operation is as follows: If the above abnormal situation occurs, the scraper 9 will no longer move downward when contacting the top surface of the battery, so that the adjacent moving rod 8 will no longer move downward, and the pressing frame 7 will drive the slider 18, the screw rod 19, the second spring 20 and the pressing block 21 to continue to descend as a whole. The pressing block 21 moves backward under the squeezing action of the moving rod 8, and the second spring 20 is compressed, thereby achieving the effect of releasing force.

[0040] Embodiment 4: On the basis of Embodiment 3, it further includes three slide bars 22 uniformly distributed laterally along the workbench 1, the slide bars 22 are slidably connected to the workbench 1, and a push rack 23 is slidably connected between the front ends of all the slide bars 22 along the up and down directions, the front side surface of the push rack 23 is in contact with the top rack 12, and the contact surface of the push rack 23 is set as a wedge-shaped surface inclined rearward and downward, the upper part of the push rack 23 is used to push the rear part of the battery backward, and a third spring 24 is fixedly connected between the slide bar 22 and the workbench 1.

[0041] When the top frame 12 flips the front battery strip upward, the top frame 12 first pushes the push frame 23 to slide upward relative to the slide bar 22 to between the battery strip in the front and the remaining batteries to be removed and disassembled at the rear. When the push frame 23 moves upward to the limit, the top frame 12 continues to move upward to squeeze the push frame 23 to move backward, and the push frame 23 drives the slide bar 22 to slide backward, and the third spring 24 is compressed. In this way, with the help of the thrust of the second electric push rod 11, the remaining batteries to be disassembled at the rear are pushed backward for a distance, making room for the flipping of the battery strip, thereby facilitating the smooth flipping of the battery strip.

[0042] When the top frame 12 moves downward to reset, the third spring 24 resets and drives the slide bar 22 to slide forward, thereby driving the push frame 23 to slide forward and reset. After the front battery strip is debonded to the right and disassembled into battery blocks, the remaining batteries to be debonded and disassembled continue to be pushed forward until they come into contact with the push frame 23. At this time, the batteries will squeeze the push frame 23 to slide downward relative to the slide bar 22 to reset.

[0043] Embodiment 5: Based on Embodiment 4, four positioning blocks 141 are further included, wherein two positioning blocks 141 are respectively fixed to the rear of the left and right sides of the workbench 1, and the other two positioning blocks 141 are respectively fixed to the rear of the left and right sides of the slide 3. The positioning blocks 141 on the slide 3 move forward and contact with the adjacent positioning blocks 141 on the workbench 1, so that the slide 3 drives the scraper 9 thereon to move forward just to contact with the bottom surface of the flipped battery strip, and the positioning blocks 141 play an accurate marking role in the forward movement distance of the slide 3.

[0044] It also includes two first magnetic blocks 25, which are respectively fixed to the two positioning blocks 141 on the slide 3, and the two positioning blocks 141 on the workbench 1 and the left and right sides of the workbench 1 are fixed with second magnetic blocks 26. The first magnetic block 25 is initially magnetically matched with the adjacent second magnetic block 26 on the workbench 1, and the first magnetic block 25 moves forward and magnetically matches with the second magnetic block 26 on the positioning block 141 on the workbench 1. In this way, through the magnetic matching of the first magnetic block 25 and the second magnetic block 26, the slide 3 can be fixed before and after driving the scraper 9 thereon to move forward, thereby making the glue removal and disassembly more stable, and preventing the slide 3 from driving the scraper 9 thereon to move forward and backward at will when scraping the glue.

[0045] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
