Description

Technical Field

[0001] The invention belongs to the technical field of battery production, and in particular relates to a battery shell repair and recycling production line. Background Art

[0002] With the development of society, battery usage continues to rise, generating a large amount of waste batteries. Waste batteries contain a large amount of heavy metals and electrolyte solutions such as waste acid and waste alkali. If discarded carelessly, waste batteries can seriously damage the natural environment. Therefore, it is extremely important to recycle and reuse used batteries.

[0003] In existing waste battery recycling, some battery casings can be repaired and reused, thus avoiding direct scrapping and resulting waste. For example, Chinese utility model CN201720177806.7 discloses an automated battery casing repair line.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figure 1 As shown, the present invention is a battery shell repair and recycling production line, which includes a bottom surface acid spraying device 100, a bottom grinding device 200, a shell grinding device 300 and a cleaning and drying device 400 which are sequentially connected in series through a conveyor line.

[0041] like Figures 2-4 As shown, the bottom surface acid shower device 100 includes a frame 101 and an acid storage water tank 102, and an acid spraying water tank 103 fixedly connected to the top of the frame 101 by bolts, and an acid pump 104 located inside the frame 101. The inner wall of the acid spraying water tank 103 is rotatably connected to a plurality of rollers 105 arranged side by side. The spacing between the rollers 105 is less than the length and width of the storage battery 1. The rollers 105 are used to cooperate with the conveyor line to transport the mobile storage battery 1 through the conveyor line so that the storage battery 1 passes through the acid spraying water tank 103 by the rollers 105. The side wall of the acid spraying water tank 103 is connected to a return pipe 112 communicated with the acid storage water tank 102.

[0042] Among them, the two outer sides of the acid spraying water tank 103 are fixedly connected with transition plates 116 by screws, which are used to allow the battery 1 to move and transition between the conveyor line and the roller 105 through the transition plate 116, so that the battery 1 on the conveyor line slides onto the roller 105 through the transition plate 116 under the action of mutual squeezing, avoiding scratches and collisions with the side walls of the acid spraying water tank 103. At the same time, the battery 1 on the roller 105 moves to the conveyor line on the other side through the transition plate 116 on the other side, thereby improving the comfort and reliability of the movement of the battery 1 through the transition plate 116.

[0043] The inlet end of the acid pump 104 is connected to the acid water storage tank 102 through a pipeline, and the outlet end of the acid pump 104 is connected to a water distribution pipe 106 through a pipeline. The water distribution pipe 106 is connected to at least one acid spray nozzle 107 through a pipeline, which can be two as shown in the figure. The acid spray nozzle 107 is located in the acid spray water tank 103 and is located in the gap between two adjacent rollers 105. It is used to spray acid toward the bottom surface of the battery through the gap between the rollers 105.

[0044] Specifically, the water distribution pipe 106 can be connected to the acid spray nozzle 107 through a universal bamboo tube, so that the position of the acid spray nozzle 107 can be flexibly adjusted. When the battery 1 moves to the roller 105 through the conveyor line, the acid spray nozzle 107 sprays acid upward, so that the acid passes through the gap between the rollers 105 and is sprayed on the bottom surface of the battery 1, thereby achieving the effect of pickling the bottom surface of the battery 1. Oxalic acid can be used as the acid. Through pickling, the rust on the bottom of the battery 1 and foreign matter in the gaps and corners are thoroughly cleaned, so that the overall cleaning convenience and cleaning efficiency are greatly improved.

[0045] At the same time, the outlet end of the acid pump 104 is connected to a shunt pipe 113 through a pipeline, and the shunt pipe 113 is arranged in parallel with the water diversion pipe 106. The shunt pipe 113 is connected to a valve, and the outlet end is connected to the acid water storage tank 102, so that when zero-time maintenance is required, the acid pumped out by the acid pump 104 can be returned to the acid water storage tank 102 through the shunt pipe 113 by opening the valve.

[0046] Be connected with other valve equally on the pipeline that is connected water diverter 106, cut off the acid solution of water diverter 106 by closing valve and enter, thereby cut off the acid solution of spraying acid nozzle 107, be convenient to adjust or overhaul fast, after overhaul is completed, open the valve at water diverter 106 places earlier, close the valve on diverter 113 again, make acid solution inject in water diverter 106 by pipeline, and be distributed in each spraying acid nozzle 107 and get final product.Wherein, spray acid water trough 103 inner bottom walls and the inner sidewall are fixedly connected with dividing plate 108, be used for spraying acid water trough 103 and be separated into liquid collecting chamber 109 and reflux chamber 110 by dividing plate 108.And spraying acid nozzle 107 is all arranged in the liquid collecting chamber 109, and reflux pipe 112 is communicated with reflux chamber 110. At the same time, a liquid partition plate 111 arranged side by side with the dividing plate 108 is fixedly connected between the two inner side walls of the acid spraying water tank 103, and the liquid partition plate 111 is located in the liquid collecting chamber 109, and the lower surface of the liquid partition plate 111 is lower than the upper surface of the dividing plate 108. By arranging the dividing plate 108 and the liquid partition plate 111, the acid solution after cleaning the bottom surface of the storage battery 1 is dripped into the liquid collecting chamber 109 again, and the flow of the acid solution is slowed down by the dividing plate 108 and the liquid partition plate 111, so that the impurities in the acid solution can be deposited in the liquid collecting chamber 109, so that the acid solution overflowing from the dividing plate 108 top into the reflux chamber 110 is relatively clean, and the clean acid solution is refluxed into the acid storage water tank 102 through the reflux pipe 112, so as to avoid that impurities are more, the acid pump 104 is worn, and the situation that the acid spraying nozzle 107 is blocked occurs.

[0047] At the same time, if Figure 5 As shown, a plurality of partition plates 114 are fixedly connected side by side to the bottom wall of the acid water storage tank 102. Taking the two shown in the figure as an example, the interior of the acid water storage tank 102 is divided by the two partition plates 114 to form three sedimentation chambers 115, and the return pipe 112 and the pipeline connected to the inlet end of the acid pump 104 are respectively connected to the two sedimentation chambers 115 that are far away from each other; that is, the acid liquid refluxed by the return pipe 112 is located in the sedimentation chamber 115 on one side of the acid water storage tank 102, and the pump body 4 is connected to the sedimentation chamber 115 on the other side through the pipeline, so that when the acid liquid overflows from above each partition plate 114, the impurities in the acid liquid are further precipitated, thereby improving the cleanliness of the acid liquid entering the acid pump 104 and the acid nozzle 107, which is conducive to further improving the overall reliability and stability of use.

[0048] like Figure 6 and 7 As shown, the bottom surface acid shower device 100 and the bottom grinding device 200 may be further equipped with a conveying device for conveying the battery 1, so that the battery 1 is moved to each workstation in sequence along the conveyor line. The bottom grinding device 200 includes a Π-shaped frame 201 located below the conveyor line. The Π-shaped frame 201 is connected to a base 202 and is fixedly connected to a telescopic device 203. The telescopic device 203 can be a hydraulic cylinder, a telescopic cylinder, or an electric push rod.

[0049] Two to four guide rods 206 are fixedly connected to the upper surface of the Π-shaped frame 201. Linear bearings 207, which mate with the guide rods 206, are fixedly connected to the base 202 via screws. The telescopic end of the telescopic mechanism 203 is connected to the base 202, driving the base 202 up and down along the guide rods 206 via the telescopic mechanism 203. A motor 204 is fixedly connected to the base 202, and a grinding wheel 205 is connected to the output shaft of the motor 204. The conveyor line is a roller conveyor, and a grinding gap is left between the conveyor rollers corresponding to the position of the grinding wheel 205, allowing the grinding wheel 205 to pass through the grinding gap to grind the bottom of the batteries on the roller conveyor line 1.

[0050] Specifically, the width of the grinding gap is smaller than the width of the battery 1. The conveying rollers at the alignment position on the roller conveyor line 1 can be removed according to the specific length of the battery 1 to form a grinding gap, or all the conveying rollers located in the area above the grinding wheel 205 can be removed, and multiple transition plates can be installed with gaps between the transition plates to form a grinding gap. When the roller conveyor line 1 conveys the battery 1, the battery 1 is connected end to end, so that the battery is pushed over the transition plate in turn.

[0051] During grinding, the conveyor line transports the battery 1, and the telescopic device 203 lifts the base 202 upward, allowing the grinding wheel 205 to contact the bottom of the battery 1 through the grinding gap. The motor 204 then drives the grinding wheel 205 to rotate, thereby grinding the bottom of the battery 1. During the grinding process, the battery 1 remains in a conveying state, thereby achieving an assembly line grinding operation and greatly improving the grinding efficiency. At the same time, the base 202 is connected to two motors 204, and the two motors 204 rotate in opposite directions, so that the two grinding wheels 205 respectively grind the bottom of the same battery 1 in two directions, thereby improving the grinding effect of the battery 1.

[0052] The Π-shaped frame 201 is welded or bolted to a support plate 208, which is vertically arranged. The support plate 208 is fixedly connected to a pressing mechanism located above the roller conveyor line 1. The pressing mechanism is used to press down the battery 1 through the pressing mechanism to ensure that the battery 1 remains stable during grinding. Specifically, the pressing mechanism includes a cylinder 209 fixedly connected to the side of the support plate 208 and a roller bar 210 connected to the telescopic end of the cylinder 209. It also includes a fixed plate 211 fixedly connected to the side of the support plate 208 and a strip plate 212 fixedly connected to the telescopic end of the cylinder 209. The roller bar 210 is connected to the strip plate 212, and the cylinder 209 is fixedly connected to the upper surface of the fixed plate 211. The fixed plate 211 is fixedly connected to two guide sleeves 213, and the strip plate 212 is fixedly connected to a guide post 214 that cooperates with the guide sleeves 213, so that the cylinder 209 drives the strip plate 212 to move up and down more smoothly and reliably.

[0053] Furthermore, the strip plate 212 is fixedly connected to two guide sleeves 215, and the upper surface of the roller bar 210 is fixedly connected to a guide rod 216 that cooperates with the guide sleeve 215. At the same time, the guide rod 216 is provided with a spring 217, and the spring 217 is located between the roller bar 210 and the strip plate 212. The upper end of the guide rod 216 is fixedly connected to a limiting nut, which is limited by the limiting nut to prevent the guide rod 216 from slipping off the guide sleeve 215.

[0054] When grinding the battery 1, the cylinder 209 drives the strip plate 212 downward, causing the roller bar 210 to press down on the upper surface of the battery 1, thereby keeping the battery 1 stable and preventing the battery 1 from jumping or moving during the grinding process, which would affect the grinding effect. In the process of the roller bar 210 pressing down on the battery 1, the spring 217 is compressed between the strip plate 212 and the roller bar 210, and the rebound force of the spring 217 is used to achieve the roller bar 210 pressing down on the battery 1, thereby preventing the roller bar 210 from directly pressing down, which could easily cause damage to the battery 1, and allowing the roller bar 210 to automatically adapt to the height position of the battery 1.

[0055] Among them, the Π-shaped frame 201 is also fixedly connected to a sensing switch 218, and the base 202 is fixedly connected to a sensing part 219. The sensing part 219 can be an iron piece that can trigger the sensing switch 218. When the base 202 is lifted upward by the telescopic device 203, the sensing part 219 is driven to move by the base 202. When the base 202 moves to the required position, the sensing part 219 is used to trigger the sensing switch 218. The trigger signal of the sensing switch 218 is fed back to the control system, thereby stopping the telescopic device 203 from continuing to lift the base 202, thereby limiting the upward position of the base 202, so that the grinding wheel 205 can be accurately lifted to the grinding position, thereby improving the grinding accuracy and grinding effect.

[0056] like Figure 8 As shown, there are two groups of shell grinding devices 300, and a reversing conveying device 500 is set between the two groups of shell grinding devices 300, which is used to convert the battery from longitudinal conveying to transverse conveying, so that the two groups of shell grinding devices 300 can grind the two outer side surfaces of the battery respectively.

[0057] like Figure 15 and 16As shown, the cleaning and drying device 400 includes a housing that spans the conveyor line, and the interior of the housing is divided into a cleaning section and a drying section. The housing is not shown in the figure. The conveyor line transports the battery 1 through the housing, passing through the cleaning section and the drying section in sequence. The cleaning section includes a first spray mechanism 401, a first cleaning mechanism 402, a reversing mechanism, a second spray mechanism 403, and a second cleaning mechanism 404, which are arranged in sequence along the conveying direction of the conveyor line. The second cleaning mechanism 404 and the first cleaning mechanism 402 have the same structure as the shell polishing device 300, and are used to clean two pairs of side surfaces of the battery through the first cleaning mechanism 402 and the second cleaning mechanism 404.

[0058] The reversing mechanism can adopt a structure that is connected to the reversing conveying device 500, or a 90° reversing mechanism to achieve the conversion of the battery conveying direction. Specifically, the battery 1 is conveyed horizontally and sprayed and cleaned by the first spray mechanism 401. When it moves to the position of the first cleaning mechanism 402, the two end faces of the battery 1 are cleaned. After the battery 1 moves through the first cleaning mechanism 402, the reversing mechanism converts the battery 1 from horizontal conveyance to longitudinal conveyance. When passing through the second spray mechanism 403, the battery is sprayed again by the second spray mechanism 403 to prevent debris or foreign matter generated when the first cleaning mechanism 402 cleans the battery 1 from adhering to the side wall of the battery 1. The second cleaning mechanism 404 then cleans the other two side faces of the battery 1, thereby completing the cleaning of all four side faces of the battery 1.

[0059] In addition, the cleaning section also includes a third spray mechanism 412, and the third spray mechanism 412 is located between the second cleaning mechanism 404 and the drying section, so that after the battery 1 is cleaned by the second cleaning mechanism 404, it is sprayed by the third spray mechanism 412 to ensure the cleanliness of the surface of the battery 1.

[0060] The cleaning section also includes a bottom spray mechanism, which can be located below the third spray mechanism 412. The nozzle of the bottom spray mechanism is located below the conveyor line 1. The conveyor line 1 can be a roller conveyor line. The nozzle sprays upward through the gap between the rollers to spray and clean the bottom surface of the battery 1, thereby further improving the thoroughness of cleaning the battery 1 and further improving the cleaning effect of the battery 1. After being sprayed and cleaned by the third spray mechanism 412, the battery 1 is transported to the drying section through the conveyor line. The drying section includes a high-pressure fan 405 and a plurality of air knives 406 located in the housing. The air knives 406 can be a combination of two pairs of standard air knives, which are used to blow dry hot air out of the air knives 406 through the high-pressure fan 405 to achieve air drying of the battery 1, thereby completing the spray cleaning and drying operations of the battery 1.

[0061] Example 2

[0062] Based on Example 1, Figure 9 and 10 As shown, the shell grinding device 300 includes a grinding frame 301 that spans above the conveyor line, which is used to convey the battery 1 through the conveyor line and pass through the grinding frame 301. The outer wall of the grinding frame 301 is connected to a grinding mechanism, which includes a mounting plate 302, and the mounting plate 302 is slidably connected to two adjustment plates 303, and is rotatably connected to a horizontally set screw rod 304. The two adjustment plates 303 are both connected to a nut that cooperates with the screw rod 304, and are fixedly connected to a grinding motor 305. The output shaft of the grinding motor 305 is connected to a side grinding wheel 306, which is used to adjust the distance between the two adjustment plates 303 by rotating the screw rod 304, so that the two side grinding wheels 306 are located on both sides of the battery 1 and grind the two opposite outer sides of the battery 1 respectively.

[0063] Specifically, a servo motor is installed on the grinding frame 301, and the servo motor is connected to the screw rod 304 through a coupling. The servo motor drives the screw rod 304 to rotate, and the distance between the two adjustment plates 303 can be adjusted according to the width of the battery 1 that needs to be ground, so that the two side grinding wheels 306 can adapt to the grinding of batteries 1 of different widths.

[0064] like Figure 11 As shown, when the battery 1 is conveyed longitudinally, that is, the length direction of the battery 1 is parallel to the conveying direction, the distance between the two adjustment plates 303 is reduced so that the distance between the two side grinding wheels 306 can achieve the width of the battery 1. As a result, when the conveyor line 1 drives the battery 1 to move between the two side grinding wheels 306, the two outer walls of the battery 1 are polished respectively by the two side grinding wheels 306, thereby improving the overall polishing efficiency.

[0065] The grinding frame 301 is also equipped with a material pressing mechanism. The roller bar 210 of the material pressing mechanism presses the battery 1 downward to limit its position, ensuring that the battery 1 remains stable when the side grinding wheel 306 grinds the side of the battery 1. Furthermore, the conveyor line 1 is a roller conveyor, and a negative pressure dust removal device is connected below the conveyor line 1 to collect dust and debris generated during grinding, preventing dust and debris from flying and affecting the workshop environment and employee health.

[0066] like Figures 8-10 As shown, after the battery 1 passes through the bottom grinding device 200, it is conveyed to the shell grinding device 300 on the left through the conveyor line. At this time, the battery 1 is conveyed longitudinally, and the two side grinding wheels 306 on the left shell grinding device 300 are used to grind the two sides of the battery 1. After grinding, the battery 1 is converted from longitudinal conveyance to transverse conveyance during the conveying process through the reversing conveying device 500.

[0067] like Figure 11 As shown, when the battery 1 transported laterally moves to the position of the shell grinding device 300 on the right, the spacing between the two side grinding wheels 306 on the shell grinding device 300 is adjusted to adapt to the width of the battery 1, thereby achieving grinding of the other two sides of the battery 1, that is, the grinding of the four sides of the battery 1 can be completed through one transport, thereby further improving the overall grinding efficiency. Among them, the outer wall of the grinding machine frame 301 is rotatably connected to a vertically arranged adjustment screw 307 through a bearing seat, and the upper end of the adjustment screw 307 is connected to a handwheel. The mounting plate 302 is slidably connected to the grinding machine frame 301 through a guide rail slider mechanism, and the mounting plate 302 is fixedly connected to a screw nut that cooperates with the adjustment screw 307, which is used to rotate the adjustment screw 307 through the handwheel to adjust the upper and lower positions of the mounting plate 302, and then adjust the upper and lower positions of the grinding mechanism, so as to facilitate the grinding of batteries 1 of different heights.

[0068] In addition, if Figure 9 As shown, the number of grinding mechanisms in each housing grinding device 300 can be one or two. When there are two grinding mechanisms, they are respectively connected to the outer side walls of two grinding racks 301, or the two grinding mechanisms are respectively connected to both sides of a grinding rack 301. The side grinding wheels 306 in the two grinding mechanisms grind the battery 1, achieving rough grinding and fine grinding effects, thereby improving the grinding effect. When the battery 1 passes through the left grinding mechanism, the two side grinding wheels 306 in the grinding mechanism perform preliminary grinding on the two outer walls of the battery 1. When the battery 1 passes through the right grinding mechanism, the spacing between the two side grinding wheels 306 is reduced, or a finer grinding wheel is replaced, so that the two side grinding wheels 306 in the grinding mechanism achieve the effect of fine grinding on the two outer walls of the battery 1, thereby making the grinding more thorough and improving the grinding effect and efficiency.

[0069] Example 3

[0070] In the first or second embodiment, if Figure 12 and 13 As shown, the reversing conveying device 500 includes a conveyor 501, and the frame on one side of the conveyor 501 is connected to the mounting side plate 502 by screws; a connecting plate 503 is welded or screwed to one side of the mounting side plate 502, the connecting plate 503 is horizontally arranged, and a vertically arranged round rod 504 is fixedly connected to the lower surface of the connecting plate 503; the round rod 504 is located above the conveyor belt or conveyor roller of the conveyor 501.

[0071] Among them, such as Figure 14As shown, the connecting plate 503 may have a connecting through-hole, and the upper end of the round rod 504 may be a stepped shaft structure with threads. The threaded section passes through the connecting through-hole and is locked with a matching nut, thereby achieving a fixed connection between the connecting plate 503 and the round rod 504. The mounting side plate 502 is fixedly connected to a reversing cylinder 505 via screws, etc., which is used to block the battery through the round rod 504 and push the side of the other end of the battery 1 through the telescopic rod of the reversing cylinder 505, causing the battery to rotate 90 degrees around the round rod 504.

[0072] Specifically, the frame of conveyor 501 is mounted with two parallel bars 506 via brackets. The spacing between the two bars 506 matches the width of the battery 1. These bars 506 guide the battery 1 so that its longitudinal direction is parallel to the conveying direction and toward the side of the mounting side panel 502. When the battery 1 reaches the round bar 504, it is blocked near the corner by the round bar 504, preventing further movement. The mounting side panel 502 has a through-hole near the round bar 504, through which a proximity switch 507 is mounted.

[0073] When the proximity switch 507 detects the battery 1, the system starts the reversing cylinder 505, and uses the telescopic rod end of the reversing cylinder 505 to push the battery 1 away from the side of one end of the round rod 504, so that the battery 1 rotates and gradually rotates under the action of the conveyor belt on the conveyor 501. When the battery 1 rotates 90°, that is, when the battery 1 rotates from the longitudinal position to the transverse position, the end of the battery 1 loses the obstruction of the round rod 504, so that the conveyor belt moves away from the position of the round rod 504 and continues to transport the battery 1 to the downward work station.

[0074] The outer wall of the round rod 504 is coated with a rubber layer, which prevents the battery 1 from being damaged by impact or collision. At the same time, the rubber layer can increase the friction between the rod and the battery 1, preventing the battery 1 from being laterally offset when the reversing cylinder 505 pushes the battery 1, thereby improving the overall reliability and stability. At the same time, the end of the telescopic rod of the reversing cylinder 505 is fixedly connected to a vertically arranged strip plate 508. The cross-section of the strip plate 508 is a U-shaped structure, and a fixing plate 509 is welded to the inside of the strip plate 508. The fixing plate 509 has a through hole. The end of the telescopic rod of the reversing cylinder 505 has a connection hole for connecting the fixing plate 509 to the telescopic rod of the reversing cylinder 505 via bolts.

[0075] The vertically positioned strip plate 508 pushes the battery 1, ensuring a more even force distribution up and down on the battery 1. This prevents the reversing cylinder 505's telescopic rod from damaging the battery 1's casing or causing it to fall. Furthermore, the U-shaped cross-section of the strip plate 508 allows the reversing cylinder 505's telescopic rod to better adapt to the rotation of the battery 1 during its forward movement, thereby effectively rotating the battery 1 and improving overall practicality and reliability.

[0076] Example 4

[0077] like Figure 17 As shown, the first spray mechanism 401 includes a Π-shaped bracket 407 spanning the conveyor line; connecting plates 408 are fixedly connected on both sides of the Π-shaped bracket 407, and the opposite sides of the connecting plate 408 are provided with downwardly inclined inclined plates 409, and the inclined plates 409 are provided with two to four mounting holes 410 for installing nozzles. By installing the nozzle on the inclined plate 409, the nozzle can better spray and clean the battery 1 when the battery 1 passes through the Π-shaped bracket 407.

[0078] Furthermore, a downwardly facing end plate 411 is provided at the end of the connecting plate 408, and the end plate 411 is provided with two to four mounting holes 410. The Pi-shaped bracket 407, connecting plate 408, and end plate 411 can be a one-piece structure formed by stamping and bending plates, or by welding multiple plates together. By installing a nozzle on the end plate 411, the front and rear positions of the battery 1 in the direction of movement are fully sprayed and cleaned, ensuring that all sides of the battery 1 are fully sprayed, resulting in a more thorough cleaning of the battery 1 and an improved spray cleaning effect.
