[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the specification of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] Please refer to Figures 1 to 3 , a core testing, cutting and gluing device, including a turntable 100, a feeding mechanism 200, an OCV testing mechanism 300, an IV testing mechanism 400, an ear shaping mechanism 500, an ear cutting mechanism 600, a gluing mechanism 700 and a detection mechanism 800. A number of fixtures 110 are arranged at intervals on the turntable 100. The feeding mechanism 200, the OCV testing mechanism 300, the IV testing mechanism 400, the ear shaping mechanism 500, the ear cutting mechanism 600, the gluing mechanism 700 and the detection mechanism 800 are sequentially arranged around the periphery of the turntable 100. The feeding mechanism 200 includes a feeding conveyor belt 210, a manipulator 220 and a positioning and photographing unit 230. The feeding conveyor belt 210 is used for conveying the cores. The manipulator 220 grabs the cores on the feeding conveyor belt 210 and places them on the fixtures 110 after passing through the positioning and photographing unit 230. The positioning and photographing unit 230 hereby takes pictures and confirms the models of the cores.

[0035] Specifically, in this embodiment, when testing the performance of the battery cell, trimming the tabs, and applying adhesive to the front end of the battery cell, the feeding conveyor belt 210 of the feeding mechanism 200 conveys the battery cell. After being conveyed to the set position, the manipulator 220 grabs the conveyed battery cell, and after passing the positioned photographing unit 230, places the grabbed battery cell on the fixture 110 of the turntable 100. The positioned photographing unit 230 uses CCD vision detection to first identify the model of the battery cell, so that the manipulator 220 can accurately place the battery cell on the fixture 110, facilitating the cooperation of the battery cell with subsequent mechanisms. At the same time, after the model of the battery cell is identified by the positioned photographing unit 230, the subsequent OCV testing mechanism 300, IV testing mechanism 400, tab shaping mechanism 500, tab trimming mechanism 600, and adhesive applying mechanism 700 will adjust themselves to match the identified battery cell. After the adjustment of each mechanism, the turntable 100 rotates with the fixture 110 and successively rotates to the OCV testing mechanism 300, IV testing mechanism 400, tab shaping mechanism 500, tab trimming mechanism 600, adhesive applying mechanism 700, and detection mechanism 800. The OCV testing mechanism 300 tests the OCV performance of the battery cell, the IV testing mechanism 400 tests the IV performance of the battery cell, then the tab shaping mechanism 500 levels the positive / negative tabs on the battery cell, and the tab trimming mechanism 600 trims the positive / negative tabs of the battery cell. After the tabs are trimmed, the adhesive applying mechanism 700 applies adhesive to the upper and lower surfaces of the front end of the battery cell. After the adhesive is applied, the detection mechanism 800 detects the lengths of the trimmed positive / negative tabs, finally completing the performance testing of the battery cell, tab trimming, and adhesive application to the front end of the battery cell. And by first identifying through the positioned photographing unit 230, the subsequent various mechanisms are adjusted, enabling the device to test different models of battery cells, trim the tabs, and apply adhesive to the front end of the battery cell, thereby improving the compatibility of the device and reducing the enterprise cost to ensure the development of the enterprise.

[0036] Of course, in this embodiment, the model of the battery cell can also be confirmed manually and then input into the control system of the device. The control system will then issue commands, enabling the subsequent OCV testing mechanism 300, IV testing mechanism 400, tab shaping mechanism 500, tab trimming mechanism 600, and adhesive applying mechanism 700 to be adjusted. Similarly, it can achieve testing different models of battery cells, trimming the tabs, and applying adhesive to the front end of the battery cell, thereby improving the compatibility of the device. At this time, the positioned photographing unit 230 can ensure the accurate placement of the battery cell on the fixture 110. Additionally, in this embodiment, the manipulator 230 can grab two battery cells simultaneously and the device can simultaneously test two battery cells, trim the tabs, and apply adhesive to the front end of the battery cells, thereby improving the efficiency.

[0037] Please refer to Figure 4 and Figure 5, in order to test the OCV performance of the battery cell, therefore, the OCV test mechanism 300 in this embodiment includes a lifting seat 310 and a probe adjustment unit 320. The bottom of the lifting seat 310 is connected to an OCV test motor 340, and the top of the lifting seat 310 is provided with an OCV test cylinder 350. The probe adjustment unit 320 is connected to the OCV test cylinder 350. The probe adjustment unit 320 includes two groups of first probes 321, and both groups of first probes 321 are connected to a first adjustment motor 322. The first adjustment motor 322 can drive the two groups of first probes 321 to move towards or away from each other to adjust the distance between the two groups of first probes 321.

[0038] After the positioning and photographing unit 230 identifies the model of the battery cell, the two first adjustment motors 322 in the probe adjustment unit 320 will drive the two groups of first probes 321 to move to adjust the distance between the two groups of first probes 321 so that the two groups of first probes 321 respectively correspond to the positive / negative electrode tabs of the battery cell. When the turntable 100 drives the battery cell on the fixture 110 to rotate to the OCV test mechanism 300, the OCV test motor 340 will drive the lifting seat 310 to move upward so that the pallet on the lifting seat 310 is placed below the electrode tab of the battery cell. At this time, the OCV test cylinder 350 drives the probe adjustment unit 320 to move downward so that the two first probes 321 of the probe adjustment unit 320 are respectively in contact with the positive / negative electrode tabs of the battery cell, thereby realizing the test of the OCV performance of battery cells of different models and improving its compatibility.

[0039] Please refer to Figures 6 to 8 , in order to detect the IV performance of the battery cell in this embodiment, the IV test mechanism 400 includes a lifting plate 410, a fixed bracket 420 and a test adjustment unit 430. The bottom of the lifting plate 410 is connected to a first driving motor 440. The fixed bracket 420 is arranged on the lifting plate 410 and is driven to move on the lifting plate 410 by a second driving motor 450. The test adjustment unit 430 is installed on the fixed bracket 420, and opposite second probes 460 and test blocks 470 are also arranged on the fixed bracket 420. The second probes 460 can be driven by a first driving cylinder 480 to approach or move away from the test blocks 470. The test adjustment unit 430 includes a second driving cylinder 431, a pushing plate 432 and two groups of test knives 433. The pushing plate 432 is connected to the second driving cylinder 431, and two groups of second adjustment motors 434 are arranged on the pushing plate 432. The two groups of test knives 433 are respectively connected to the two groups of second adjustment motors 434. The second adjustment motors 434 drive the two groups of test knives 433 to move towards or away from each other to adjust the distance between the two groups of test knives 433.

[0040] Similarly, after the positioning and photographing unit 230 identifies the model of the battery cell, two sets of second adjustment motors 434 in the test adjustment unit 430 will drive two sets of test knives 433 to move, so as to adjust the distance between the two sets of test knives 433 to match the position of the battery cell. When the turntable 100 drives the battery cell to rotate to the IV test mechanism 400, the first drive motor 440 will drive the lifting plate 410 to move up and down, and at the same time, the second drive motor 450 will drive the fixed bracket 420 to move left and right. Then, the first drive cylinder 480 will drive the second probe 460 to move downward, so that the second probe 460 and the test support block 470 contact and clamp the positive electrode tab of the battery cell. At the same time, the second drive cylinder 431 will drive the push plate 432 to move forward, so that the two sets of test knives 433 cut the front end of the battery cell, thereby realizing the IV test of the battery cell. And by driving the two sets of test knives 433 to move towards or away from each other by the two sets of second adjustment motors 434, the IV performance of battery cells of different models can be tested, improving its compatibility.

[0041] Please refer to Figure 9 , in this embodiment, before trimming the tabs of the battery cell, the tabs need to be leveled. Therefore, the tab shaping mechanism 500 includes a shaping fixed seat 510, a transverse movement module 520, an upper shaping unit 530, and a lower shaping unit 540. The transverse movement module 520 and the lower shaping unit 540 are respectively arranged at the top and bottom of the shaping fixed seat 510. The upper shaping unit 530 is connected to the transverse movement module 510 and is located above the lower shaping unit 540. The upper shaping unit 530 includes an upper shaping cylinder 531, a shaping connection plate 532, and a shaping adjustment plate 533. The shaping connection plate 532 is connected to the upper shaping cylinder 531. Two sets of shaping adjustment plates 533 are provided and are movably arranged on the shaping connection plate 532. The distance between the two sets of shaping adjustment plates 533 can be adjusted, and a fixed block 534 is arranged on the shaping adjustment plate 533. The bottom of the fixed block 534 has a roller 535. The lower shaping unit 540 includes a lower shaping cylinder 541 and a lower shaping drive plate 542. The lower shaping drive plate 542 is connected to the lower shaping cylinder 541, and a shaping plate 543 is arranged on the lower shaping drive plate 542.

[0042] After the turntable 100 rotates the jig 110 to the shaping mechanism, the tab of the battery cell will be placed between the upper shaping unit 530 and the lower shaping unit 540. At this time, the upper shaping cylinder 531 of the upper shaping unit 530 will drive the shaping connecting plate 532 to move downward and drive the shaping adjustment plate 533 to move downward. When the shaping adjustment plate 533 moves downward, it drives the fixing block 534 downward, so that the roller 535 acts on the tab. At the same time, the lower shaping cylinder 541 of the lower shaping unit 540 will drive the lower shaping driving plate 542 to move upward, thereby driving the shaping plate 543 to move upward to contact the bottom of the tab. After the roller 535 and the shaping plate 543 act on the upper and lower surfaces of the tab respectively, the transverse movement module 520 will drive the upper shaping unit 530 to move back and forth, so that the roller 545 rolls the tab to achieve the leveling of the tab. Since there are positive / negative tabs on the battery cell, there are two groups of shaping adjustment plates 533, and the distance between the two groups of shaping adjustment plates 533 can be adjusted manually or automatically to match the distance between the positive / negative tabs, improving the compatibility of the equipment.

[0043] Please refer to Figure 10 and Figure 11 , after the tab is leveled, the length of the tab needs to be cut. Therefore, the tab cutting mechanism 600 in this embodiment includes a Z-axis transmission module 610, a Y-axis transmission module 620, an X-axis transmission module 630, and a cutting unit 640. The Y-axis transmission module 620 is connected to the Z-axis transmission module 610, the X-axis transmission module 630 is connected to the Y-axis transmission module 620, and the cutting unit 640 is connected to the X-axis transmission module 630. The cutting unit 640 includes a cutting fixed seat 641, a cutting driving member 642, an upper cutting knife 643, and a lower cutting knife 644. The cutting driving member 642 is arranged at the top of the cutting fixed seat 641, the lower cutting knife 644 is arranged at the lower end of the cutting fixed seat 641, and the upper cutting knife 643 is connected to the cutting driving member 642 and is located above the lower cutting knife 644.

[0044] After the turntable 100 rotates the battery cell on the fixture 110 to the ear cutting mechanism 600, the Z-axis drive module 610, Y-axis drive module 620, and X-axis drive module 630 will adjust the height, front-back, and left-right positions of the cutting unit 640 to make the cutting unit 640 cooperate with the ears of the battery cell and place the ears of the battery cell between the upper cutting knife 643 and the lower cutting knife 644. At this time, the upper cutting knife 643 is driven by the cutting drive member 642 to move downward, so that the upper cutting knife 643 cooperates with the lower cutting knife 644 to cut the ears of the battery cell, thereby realizing the cutting of the positive / negative ears of the battery cell. And because the widths of the upper cutting knife 643 and the lower cutting knife 644 are relatively wide, no further adjustment is required to cut the ears of battery cells of different models, thus improving its compatibility. The Z-axis drive module 610, Y-axis drive module 620, and X-axis drive module 630 can all adopt the structure of a motor and a lead screw. This structure is an existing technology, so it will not be elaborated here.

[0045] Please refer to Figures 12 to 14 , after cutting the ears of the battery cell, it is also necessary to stick single-sided adhesive on both the upper and lower surfaces of the front end of the battery cell. Therefore, the adhesive sticking mechanism 700 in this embodiment includes an adhesive sticking fixed seat 710, a feeding tray 720, a guide wheel 730, a conveying channel 740, a cutting unit 750, a material pulling unit 760, and an adhesive sticking group 770. The feeding tray 720, guide wheel 730, conveying channel 740, and cutting unit 750 are respectively provided with two groups and are arranged vertically on the adhesive sticking fixed seat 710. The material pulling unit 760 is connected to the adhesive sticking fixed seat 710, and the adhesive sticking group 770 is located between the cutting unit 750 and the material pulling unit 760; the conveying channel 740 includes a conveying movable plate 741 and a conveying fixed plate 742 arranged vertically, and the conveying movable plate 741 is connected to a conveying cylinder 743. The conveying cylinder 743 drives the conveying movable plate 741 to approach or move away from the conveying fixed plate 742; the cutting unit 750 includes a cutting cylinder 751, a cutting connecting plate 752, and a cutting knife 753. One end of the cutting connecting plate 752 is connected to the cutting cylinder 751, and the other end is connected to the cutting knife 753. The cutting cylinder 751 drives the cutting connecting plate 752 to move, thereby driving the cutting knife 753 to move up and down; the material pulling unit 760 includes a material pulling drive member 761, a material pulling plate 762, and material pulling jaws 763. The material pulling plate 762 is connected to the material pulling drive member 761. The material pulling jaws 763 are provided with two groups and are respectively connected to the material pulling plate 762. The material pulling drive member 761 drives the material pulling plate 762 to move, thereby making the material pulling jaws 763 approach or move away from the corresponding conveying channel 740.

[0046] The glue - applying group 770 includes a glue - applying transverse movement unit 771, a glue - applying longitudinal movement unit 772, a lateral adjustment unit 773, and a longitudinal adjustment unit 774. The glue - applying longitudinal movement unit 772 is connected to the glue - applying transverse movement unit 771. The lateral adjustment unit 773 is connected to the glue - applying longitudinal movement unit 772. The longitudinal adjustment unit 774 is connected to the lateral adjustment unit 773. And there are two groups of suction heads 775 provided on the longitudinal adjustment unit 774. The longitudinal adjustment unit 774 can adjust the up - and - down positions of the two groups of suction heads 775.

[0047] Specifically, when applying glue, single - sided adhesive rolls are respectively installed on the two feeding trays 720. The feeding trays 720 convey the single - sided adhesive, and the material - pulling unit 760 pulls the single - sided adhesive, so that the single - sided adhesive passes through a number of guide wheels 730, a conveying channel 740, a cutting unit 750, and the glue - applying group 770 in sequence. During the conveying process of the single - sided adhesive, the first guide wheel 730 limits the conveyed single - sided adhesive to prevent the single - sided adhesive roll from being too loose when pulled and conveyed. When pulling the single - sided adhesive, the material - pulling jaw 763 in the material - pulling unit 760 clamps the starting end of the single - sided adhesive, and the material - pulling driving part 761 drives the material - pulling plate 762 to move horizontally, so that the material - pulling jaw 763 pulls a set length of the single - sided adhesive. After the pulling is completed, the conveying cylinder 743 of the conveying channel 740 drives the conveying movable plate 741 to move downward, so as to cooperate with the conveying fixed plate 742 to clamp and fix the conveyed single - sided adhesive. At this time, the cutting cylinder 751 of the cutting unit 750 drives the cutting connecting plate 751 to move, so that the cutting knife 752 cuts off the conveyed single - sided adhesive. The cut single - sided adhesive is then sucked by the suction heads 775 in the glue - applying group 770. The turntable 100 rotates the battery cell on the fixture 110 to the glue - applying mechanism 700. After the suction heads 775 suck the single - sided adhesive, the glue - applying transverse movement unit 771 and the glue - applying longitudinal movement unit 772 drive the suction heads 775 to move towards the battery cell on the fixture 110. Then, the lateral adjustment unit 773 adjusts the lateral direction of the suction heads 775, so that the two groups of suction heads 775 are respectively located directly above and directly below the front end of the battery cell. After the position is adjusted, the longitudinal adjustment unit 774 drives the two groups of suction heads 775 to move, so as to paste the sucked single - sided adhesive onto the upper and lower surfaces of the front end of the battery cell, finally realizing the glue - applying to the front end of the battery cell. And through the glue - applying group 770, the height, left - right, and front - back positions of the suction heads can be adjusted to match different models of battery cells, thereby improving its compatibility.

[0048] Finally, please refer to Figure 1 and Figure 2, the detection mechanism 800 in this embodiment is CCD vision detection.
