Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, and in particular to a battery pole milling device. Background Art

[0002] With the increasing number of used batteries, battery recycling can achieve resource recycling. A battery module can be understood as a combination of multiple batteries connected in series and parallel via conductive bars (aluminum or copper). When disassembling a battery module for recycling, the conductive bars must first be removed to separate the individual batteries in the module.

[0003] At present, most battery module dismantling methods are to cut the conductive bars with a milling cutter to obtain single cells. After obtaining the single cells, in order to facilitate subsequent recycling, the batteries need to be reprocessed, specifically the battery poles need to be milled and chamfered. In the prior art, the operator first labels the batteries and then transports the batches of batteries by means of a feeding trolley or other carrying tool to the milling cutter equipment for the battery pole milling process. After completing the milling process, the operator then sends the batches of batteries to the chamfering equipment for the battery pole chamfering process. After completing the chamfering process, the operator continues to send the batches of batteries to the cleaning equipment and testing equipment behind in turn to complete the final cleaning and performance testing work, thus completing the entire battery milling process. It can be seen that the operation method in the prior art requires the operator to transport the batteries multiple times, which undoubtedly greatly wastes the time of equipment operation and has a serious impact on operation efficiency.

[0070] An embodiment of the present invention discloses a battery pole milling device, which is used to solve the technical problem that multiple processes involved in the existing battery pole milling process need to be performed on different devices respectively, resulting in operators having to transfer batteries multiple times and causing relatively low operating efficiency.

[0071] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0072] See also Figures 1 to 12 A battery pole milling device provided in an embodiment of the present invention includes a frame 1, a battery bulge detection mechanism 2 for performing a bulge test on a battery, a positioning mechanism 3 for positioning the battery, a labeling mechanism 4 for attaching a label to the battery, a pole milling mechanism 5 for milling and chamfering the battery pole, a cleaning mechanism 6 for cleaning the battery, and a battery testing mechanism 7 for testing the battery;

[0073] The battery bulge detection mechanism 2, the positioning mechanism 3, the labeling mechanism 4, the pole milling mechanism 5, the cleaning mechanism 6, and the battery testing mechanism 7 are sequentially installed on the frame 1. Specifically, the above-mentioned mechanisms are sequentially installed on the frame 1 in a first horizontal direction;

[0074] A feeding mechanism 9 is also installed on the frame 1 , and the feeding mechanism 9 is used to sequentially transport the batteries from the positioning mechanism 3 to the labeling mechanism 4 , the pole milling mechanism 5 , the cleaning mechanism 6 and the battery testing mechanism 7 .

[0075] It should be noted that the battery in this embodiment specifically includes two first side surfaces arranged opposite to each other and two second side surfaces adjacent to the first side surfaces. The two second side surfaces are also arranged opposite to each other, wherein the battery poles are located on the second side surfaces. In one specific embodiment, the positive pole is located on one of the second side surfaces, and the negative pole is located on the other second side surface.

[0076] In this embodiment, the battery bulge detection mechanism 2, positioning mechanism 3, labeling mechanism 4, terminal milling mechanism 5, cleaning mechanism 6, and battery testing mechanism 7 are sequentially mounted on the frame 1. The feeding mechanism 9 sequentially transports the batteries from the positioning mechanism 3 to the labeling mechanism 4, terminal milling mechanism 5, cleaning mechanism 6, and battery testing mechanism 7, thereby completing the battery labeling process, the battery terminal milling process, the battery terminal chamfering process, the battery cleaning process, and the battery testing process on the same device. Through this design, multiple processes required for battery milling can be completed on the same device, greatly improving operational efficiency.

[0077] Furthermore, the positioning mechanism 3, labeling mechanism 4, pole milling mechanism 5, cleaning mechanism 6 and battery testing mechanism 7 in this embodiment all include a positioning jig 8 for positioning the battery;

[0078] The positioning fixture 8 includes a first horizontal moving module 801, a second horizontal moving module 802, a first limiting plate 804, a first cylinder 805, a first push plate 806, a support base 803 for supporting the battery, and a first limiting plate 804 disposed on the support base 803 and for abutting against the first side surface of the battery;

[0079] The first horizontal moving module 801 and the second horizontal moving module 802 are arranged opposite to each other, and the first horizontal moving module 801 and the second horizontal moving module 802 are both connected with the support seat 803 and the first cylinder 805. The two first cylinders 805 and the two support seats 803 are arranged one by one. The two support seats 803 can be moved closer to or away from each other under the drive of the first horizontal moving module 801 and the second horizontal moving module 802 respectively. The first push plate 806 is connected to the first cylinder 805. The first push plate 806 can be moved toward the direction of the battery under the drive of the first cylinder 805 to cooperate with the first limit plate 804 to clamp the battery.

[0080] It should be noted that the feeding mechanism 9 places the battery on the top surface of the two support seats 803, the two support seats 803 support one battery at the same time, and the first limit plate 804 on the support seat 803 abuts against the first side surface of the battery. The first push plate 806 moves toward the direction of the battery under the drive of the first cylinder 805 and cooperates with the first limit plate 804 to clamp the battery, thereby limiting the displacement of the battery in the first horizontal direction.

[0081] In addition, since the two support seats 803 can be moved closer to or away from each other under the drive of the first horizontal movable module 801 and the second horizontal movable module 802 respectively, through the above design, the positioning fixture 8 in this embodiment can be suitable for batteries of different sizes, greatly increasing the scope of application of the battery pole milling equipment in this embodiment.

[0082] Furthermore, the battery bulge testing mechanism in this embodiment includes a tenth air cylinder 205, a first label printer 202, a servo electric cylinder 201, a lower pressing plate 203, and a test fixture 204 for positioning the battery;

[0083] The tenth air cylinder 205 is connected to the test fixture 204 , and the test fixture 204 can be moved to the bottom of the servo electric cylinder 201 under the drive of the tenth air cylinder 205 , and the lower pressing plate 203 is connected to the servo electric cylinder 201 ;

[0084] The test fixture 204 is driven to move below the servo cylinder 201 , and the servo cylinder 201 drives the lower pressing plate 203 to move downward in the vertical direction to press the battery on the test fixture 204 ;

[0085] The first label printer 202 is located on one side of the test fixture 204 .

[0086] It should be noted that the specific principle of the above-mentioned battery bulge test mechanism is as follows: the battery is placed on the test fixture 204, and the tenth cylinder 205 drives the test fixture 204 to move below the servo cylinder 201. The servo cylinder 201 then drives the lower pressure plate 203 to press the battery downward. Based on the downward torque feedback of the servo cylinder 201, the actual stroke of the servo cylinder 201 is obtained to determine whether the battery is bulging. If the battery is bulging, the downward pressure height of the servo cylinder 201 will be less than the preset value. The first label printer 202 prints a label, and the operator affixes the label to the defective battery (bulging battery). The operator then manually removes the defective battery with bulge.

[0087] Furthermore, the positioning mechanism 3 in this embodiment includes a first positioning component and the positioning fixture 8;

[0088] The first positioning assembly includes a second cylinder 301 and a second push plate 302;

[0089] The second cylinder 301 is located on the second side adjacent to the first side of the battery. A second limit plate is also provided on a support seat 803 away from the second cylinder 301. The second push plate 302 is connected to the second cylinder 301. The second cylinder 301 drives the second push plate 302 to move toward the direction of the battery to cooperate with the second limit plate to clamp the battery.

[0090] It should be noted that the specific principle of the positioning mechanism 3 in this embodiment is: after the battery completes the bulging test, the battery is transferred to the positioning fixture 8 in the positioning mechanism 3, and then the second cylinder 301 drives the second push plate 302 to move toward the direction of the battery to cooperate with the second limit plate to clamp and position the battery, thereby limiting the displacement of the battery in the second horizontal direction.

[0091] Through the design of the positioning mechanism 3, the displacement of the battery in the first horizontal direction and the second horizontal direction can be restricted, so that the battery can be centrally positioned, making it easier for the feeding mechanism 9 to accurately grasp the battery.

[0092] Furthermore, the labeling mechanism 4 in this embodiment includes a second label printer 403, a first suction component 402, a second suction component 404, a third horizontal moving module 401 and the positioning fixture 8;

[0093] The first suction component 402 is located at the label discharge end of the second label printer 403 to absorb the label. The third horizontal movable module 401 is connected to the second suction component 404. The second suction component 404 can move back and forth between the positioning fixture 8 and the first suction component 402 under the drive of the third horizontal movable module 401 to attach the label on the first suction component 402 to the battery.

[0094] The labeling mechanism 4 further includes a first barcode scanner 407 for scanning the label attached to the battery, a clamping assembly 405 for clamping the battery, and an NG battery collection fixture 406; the clamping assembly 405 and the first barcode scanner 407 are both connected to the third horizontal moving module 401;

[0095] The first barcode scanner 407 can be moved to the top of the positioning fixture 8 under the drive of the third horizontal moving module 401 to scan the label on the battery;

[0096] The clamping assembly 405 can move back and forth between the positioning jig 8 and the NG battery collecting jig 406 under the drive of the third horizontal moving module 401 .

[0097] It should be noted that the specific working principle of the labeling mechanism 4 in this embodiment is as follows:

[0098] After the battery is sent to the positioning fixture 8 of the labeling mechanism 4 by the feeding mechanism 9, the second label printer 403 prints the label and outputs the label to the label discharge end. The first suction component 402 absorbs the label. Then, the third horizontal moving module 401 drives the second suction component 404 to move to the first suction component 402 and absorb the label. After absorbing the label, the second suction component 404 moves to the positioning fixture 8 under the drive of the third horizontal moving module 401. The second suction component 404 sticks the label on the battery. Then, the first barcode scanner 407 moves under the drive of the third horizontal moving module 401. Move to the top of the battery and scan the label on the battery to determine whether the battery information is OK. If the battery information shows NG, the current battery is determined to be an NG battery. At this time, the clamping component 405 is driven by the third horizontal moving module 401 to move to the positioning jig 8 and clamp the NG battery. After clamping the NG battery, the clamping component 405 is driven by the third horizontal moving module 401 to move to the NG battery collection jig 406. The NG battery collection jig 406 recycles the NG battery. Finally, the operator takes the NG battery away from the NG battery collection jig 406.

[0099] Specifically, the first suction component 402 in this embodiment specifically includes an eighth cylinder 4021 and a first negative pressure suction head 4022 connected to the eighth cylinder 4021. The first negative pressure suction head 4022 is driven to move to the label discharge end of the second label printer 403 to absorb the adhesive surface of the label. It should be noted that the suction end of the first negative pressure suction head 4022 is an anti-stick surface.

[0100] The second suction component 404 in this embodiment specifically includes a second lifting module 4041 and a second negative pressure suction head 4042 connected to the second lifting module 4041. When the second suction component 404 moves above the battery, the second negative pressure suction head 4042 is driven to move downward to adhere the label to the surface of the battery.

[0101] The gripping assembly 405 in this embodiment specifically includes a third lifting module 4051, a second clamping cylinder, and a second clamping jaw 4052 connected to the second clamping cylinder. When the gripping assembly 405 is driven to move above the battery, the third lifting module 4051 drives the second clamping cylinder to descend a preset distance, which then drives the second clamping jaw 4052 to clamp the battery. To prevent the battery from falling while being gripped by the second clamping jaw 4052, a hook 4053 is provided at the bottom of the second clamping jaw 4052 to support the bottom of the battery.

[0102] Furthermore, the pole milling mechanism 5 in this embodiment includes a milling assembly and the positioning fixture 8;

[0103] The milling assembly includes a fourth horizontal moving module 501, a first lifting module 502, a tool setting instrument 505, a laser displacement sensor 511, a CCD detection module 512, a milling cutter module 503 for milling the battery pole, and a chamfering cutter module 504 for chamfering the battery pole;

[0104] The first lifting module 502 is connected to the fourth horizontal moving module 501 , and the milling cutter module 503 and the chamfering cutter module 504 are both connected to the first lifting module 502 ;

[0105] The milling cutter module 503 includes a first horizontally movable sub-module 5031 , a first fixed base 5032 , a first driving member 5033 and a milling cutter 5034 ;

[0106] The first horizontally movable submodule 5031 is connected to the first lifting module 502, and the first fixed seat 5032 is connected to the first horizontally movable submodule 5031. The first horizontally movable submodule 5031 is used to drive the first fixed seat 5032 to move along the second horizontal direction. The first driving member 5033 is installed on the first fixed seat 5032, and the milling cutter 5034 is connected to the first driving member 5033.

[0107] The chamfering knife module 504 includes a second horizontally movable sub-module 5041, a second fixed base 5042, a second driving member 5043 and a chamfering knife 5044;

[0108] The second horizontally movable submodule 5041 is connected to the first lifting module 502, and the second fixed seat 5042 is connected to the second horizontally movable submodule 5041. The second horizontally movable submodule 5041 is used to drive the first fixed seat 5032 to move along the second horizontal direction. The second driving member 5043 is installed on the second fixed seat 5042, and the chamfering knife 5044 is connected to the second driving member 5043.

[0109] The laser displacement sensor 511 is located between the milling cutter 5034 and the chamfering cutter 5044. The detection end of the laser displacement sensor 511 is arranged toward the battery. The tool setting instrument 505 is used to detect the distance from the milling cutter 5034 to the laser sensor and the distance from the chamfer to the laser sensor.

[0110] The detection end of the CCD detection module 512 is disposed toward the battery.

[0111] It should be noted that the specific principle of the pole milling mechanism 5 in this embodiment is:

[0112] After the battery is delivered from the labeling mechanism 4 to the positioning fixture 8 of the terminal milling mechanism 5 by the feeding mechanism 9, the laser displacement sensor 511 detects the distance between the second side surface of the battery and the outermost end surface of the terminal, thereby obtaining the distance that the milling cutter 5034 needs to mill. Subsequently, based on the signal feedback from the laser displacement sensor 511, the fourth horizontal moving module 501, the first lifting module 502, and the first horizontal moving sub-module 5031 drive the milling cutter 5034 to move, and under the drive of the first driving member 5033, the milling cutter 5034 performs the milling process on the battery terminal. After the milling process is completed, the CCD detection module 512 photographs and detects the contour of the milled terminal to obtain image information. Based on the image information feedback obtained by the CCD detection module 512, the fourth horizontal moving module 501, the first lifting module 502, and the second horizontal moving sub-module 5041 drive the chamfering cutter 5044 to move, and under the drive of the second driving member 5043, the chamfering process is performed on the battery terminal.

[0113] In addition, the specific principle of the above-mentioned tool setting instrument 505 is: after the milling cutter module 503 and the chamfering cutter module 504 are replaced with new milling cutters 5034 and chamfering cutters 5044 respectively, it is necessary to use the tool setting instrument 505 to detect the distances between the milling cutter 50343 and the chamfering cutter 5044 and the laser displacement sensor 511 respectively, so as to adjust the working position of the milling cutter 5034 through the fourth horizontal moving module 501, the first lifting module 502 and the first horizontal moving sub-module 5031, and adjust the working position of the chamfering cutter 5044 through the fourth horizontal moving module 501, the first lifting module 502 and the second horizontal moving sub-module 5041.

[0114] Furthermore, the milling assembly in this embodiment further includes a temperature sensor 506 for detecting the temperature of the battery;

[0115] The pole milling mechanism 5 further includes an explosion-proof water tank 507, a third cylinder 513, and a connecting plate 514 connected to the third cylinder 513;

[0116] The explosion-proof water tank 507 is located below the support base 803;

[0117] The first horizontal moving module 801 and the second horizontal moving module 802 are both connected to the third cylinder 513, and the third cylinder 513 is connected to a connecting plate 514, and the connecting plate 514 is connected to the support base 803;

[0118] When the temperature sensor 506 detects that the temperature of the battery exceeds a preset range, the third cylinder 513 drives the connecting plate 514 to move the support base 803 horizontally, so that the battery loses support and falls into the explosion-proof water tank 507.

[0119] It should be noted that when the temperature sensor 506 detects that the temperature of the battery exceeds the preset range during the milling and chamfering of the battery pole, the third cylinder 513 drives the connecting plate 514 to drive the support base 803 to move horizontally, thereby causing the support base 803 to be misaligned with the battery, and then the battery loses support and falls into the explosion-proof water tank 507, ensuring operational safety.

[0120] Furthermore, in order to prevent the battery in this embodiment from jumping during the milling and chamfering process, the pole milling mechanism 5 in this embodiment further includes a pressing assembly;

[0121] Specifically, the clamping assembly includes a ninth cylinder 508 and a clamping plate 509 connected to the ninth cylinder 508. The ninth cylinder 508 is specifically located above the positioning fixture 8. Before the milling and chamfering processes are started, the clamping plate 509 moves downward in the vertical direction under the drive of the ninth cylinder 508 to press the battery onto the support seat 803.

[0122] Furthermore, in order to absorb the dust generated during the milling process and the chamfering process, a second dust hood 510 is installed on the first fixed seat 5032 and the second fixed seat 5042. The second dust hood 510 is used to absorb the dust generated during the above processes.

[0123] Furthermore, in order to further improve the working efficiency, preferably, the number of the milling assemblies in this embodiment is two;

[0124] The two milling assemblies are symmetrically arranged with respect to the positioning fixture 8 .

[0125] It should be noted that, in actual operation, the two milling assemblies mentioned above simultaneously perform the milling process and the chamfering process on the poles on the two opposite second side surfaces of the battery.

[0126] Furthermore, the cleaning mechanism 6 in this embodiment includes the positioning fixture 8, a bidirectional lead screw 601 and a fourth cylinder 602;

The fourth cylinder 602 is mounted on the mounting plate, and the fourth cylinder 602 is connected to a brush 603 and a first dust cover 604;

[0128] The brush 603 and the first dust collecting cover 604 can move downward in a vertical direction under the drive of the fourth cylinder 602 to scrape and clean the battery poles and collect dust respectively.

[0129] It should be noted that the specific principle of the cleaning mechanism 6 in this embodiment is:

[0130] The feeding mechanism 9 delivers the battery from the pole milling mechanism 5 to the positioning fixture 8 on the cleaning mechanism 6. The third driving member drives the bidirectional screw 601 to rotate so that the two fourth cylinders 602 move closer to or away from each other, so that they can adapt to batteries of different widths. After the adjustment is completed, the fourth cylinder 602 drives the brush 603 to clean the second side of the battery. At the same time, the first dust hood 604 absorbs the dust generated by the cleaning process to avoid polluting the working environment and avoiding re-polluting the battery.

[0131] Furthermore, the battery testing mechanism 7 in this embodiment includes the positioning fixture 8, a testing probe 703, a fifth cylinder 702 and a second barcode scanner 701;

[0132] The fifth cylinder 702 is provided on both the first horizontal moving module 801 and the second horizontal moving module 802 . The test probe 703 is connected to the fifth cylinder 702 . Driven by the fifth cylinder 702 , the test probe 703 moves toward the battery pole to make conductive contact with the battery pole.

[0133] It should be noted that the specific principle of the battery testing mechanism 7 of this embodiment is:

[0134] The feeding mechanism 9 delivers the battery from the cleaning mechanism 6 to the positioning fixture 8 on the battery testing mechanism 7. The fifth cylinder 702 drives the test probe 703 to contact the poles on opposite sides of the battery to measure the battery's OCV and internal resistance and upload the data. After the test is completed, the second barcode scanner 701 scans the label on the battery, and the software then binds the scanned information to the test results.

[0135] In another specific embodiment, if the positive and negative poles are located on the same side of the battery, the two test probes 703 can be disposed on the same side of the battery to facilitate conductive contact with the poles on the same side.

[0136] Furthermore, the feeding mechanism 9 in this embodiment includes a conveying frame 902 , a fifth horizontal moving module 901 , a sixth cylinder 903 , a seventh cylinder 904 , a first clamping cylinder 905 and a first clamping claw 906 ;

[0137] The conveying frame 902 is connected to the fifth horizontal moving module 901, the sixth cylinder 903 is installed on the conveying frame 902, the seventh cylinder 904 is connected to the sixth cylinder 903, and the sixth cylinder 903 is used to drive the seventh cylinder 904 to move in the vertical direction.

The first clamping jaw 906 is connected to the first clamping jaw cylinder 905, and the first clamping jaw cylinder 905 is used to drive the first clamping jaw 906 to grab the battery placed on the positioning fixture 8.

[0138] It should be noted that the specific principle of the feeding mechanism 9 in this embodiment is:

[0139] The fifth horizontal moving module 901 is used to drive the conveying frame 902 to move in the first horizontal direction. When conveying batteries, after the battery processing on the current mechanism is completed, the seventh cylinder 904 drives the first clamping cylinder 905 to move upward, and the first clamping cylinder 905 drives the first clamping claw 906 to clamp the battery on the positioning fixture 8. Then the sixth cylinder 903 drives the seventh cylinder 904, the first clamping claw 906 and the battery to move upward as a whole so as to exceed the height of the positioning fixture 8. Then the fifth horizontal moving module 901 drives the conveying frame 902 to move, thereby conveying the battery to the positioning fixture 8 of the next mechanism. After the battery cell is conveyed to the next mechanism, the seventh cylinder 904 and the sixth cylinder 903 drive the battery to fall, and the first clamping claw 906 releases the battery so that the battery is placed on the positioning fixture 8 of the mechanism.

[0140] Furthermore, in this embodiment, the first horizontal moving module 801, the second horizontal moving module 802, the tenth cylinder 205, the third horizontal moving module 401, the fourth horizontal moving module 501, the fifth horizontal moving module 901, the first horizontal moving sub-module 5031, and the second horizontal moving sub-module 5041 are first selected as linear drive modules with driving parts (servo motors) combined with screw drive, belt drive, or chain drive.

[0141] Furthermore, in this embodiment, the first horizontal direction can be simply understood as the X-axis direction, the second horizontal direction can be simply understood as the Y-axis direction, and the vertical direction can be simply understood as the Z-axis direction.
