Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery module assembly, and in particular to an automated assembly platform for battery life lithium battery modules. Background Art

[0002] Lithium batteries use lithium metal or lithium alloys as their negative electrode materials and utilize a non-aqueous electrolyte solution, hence the name lithium metal battery. Compared to other batteries, lithium batteries boast high energy density, long lifespan, and high unit cost. With the advancement of science, technology, and society, lithium batteries are increasingly widely used and have become an indispensable necessity in modern society, providing stable and safe power for electrical devices.

[0003] In the prior art, the battery cell body 6 is an important component of the lithium battery module. Taking the cylindrical battery cell body 6 as an example, its positive and negative electrodes are respectively located at the two ends of the battery cell body 6. A key operation in the assembly process of the lithium battery module is to arrange a number of battery cell bodies 6 in a rectangular array and assemble them into the pre-opened receiving grooves on the base. This process usually requires the use of a dispensing machine to dispense glue on the base, and the ends of the battery cell body 6 are bonded to the receiving grooves by glue to improve the assembly stability. However, during the transportation and loading process of the battery cell body 6, dust is easily adhered to its ends, which will reduce the adhesion of the glue to the battery cell body 6.

[0004] In addition, existing assembly equipment usually arranges single-row battery cell bodies 6 in parallel to form a battery cell group, and then assembles several battery cell groups in series on the base. When performing series welding between the electrodes of adjacent battery cell groups, it is necessary to ensure that the electrodes of adjacent battery cell groups are in opposite directions (that is, the positive pole of one battery cell group is opposite to the negative pole of the adjacent group). This requires that the battery cells need to be manually pre-arranged according to the arrangement required for the final series connection before transportation and loading, which leads to reduced loading efficiency and affects the processing efficiency of the overall equipment. Summary of the Invention

[0005] The purpose of the present invention is to provide an automated assembly platform for lithium battery modules with long battery life to solve the problems raised in the above background technology:

[0006] During the transportation and loading process, dust easily adheres to the ends of the battery cell body, reducing the adhesion of the pre-applied glue on the base to the battery cell body.

[0007] To solve the above problems, the present invention aims to provide an automated assembly platform for a battery life lithium battery module, comprising a frame, wherein a plurality of conveying silicone rollers are arranged in a horizontal array near the top of the frame, a base is placed horizontally above the conveying silicone roller, a plurality of accommodating slots are opened in a rectangular array on the upper side wall of the base, the upper side wall of the frame is sequentially provided with a dispensing assembly and a discharging mechanism, and the base is located below the dispensing assembly and the discharging mechanism, the dispensing assembly is used to perform annular dispensing on the bottom side of each accommodating slot, the discharging mechanism comprises a second mounting frame fixedly arranged on the upper side wall of the frame, the upper side wall of the second mounting frame is provided with a blanking assembly, the blanking assembly is used to output a plurality of battery cell bodies in a single row, and the second mounting frame is provided with a movable receiving assembly for receiving the battery cell bodies output by the blanking assembly, a flip clamping mechanism is provided inside the second mounting frame, a reel dust-free cloth is provided on the flip clamping mechanism, and a reel dust-free cloth is provided at both ends of the reel.

[0008] When the silicone conveying roller conveys the glue-dispensed base to the bottom of the second mounting frame, the unloading assembly outputs the single-row battery cell bodies to the top of the mobile receiving assembly. The mobile receiving assembly receives the battery cell bodies and clamps the battery cell bodies through the flip clamping mechanism, and then rotates the flip clamping mechanism to adjust the swing angle of the battery cell body. When the battery cell body is rotated to a horizontal state, the end of the battery cell body contacts one side of the reel dust-free cloth. At this time, the mobile receiving assembly moves out from the bottom of the battery cell body. During the process of moving out, the reeling and unreeling mechanism is driven, so that the two reeling and unreeling mechanisms respectively reel in and unreel the reel dust-free cloth.

[0009] As a further improvement of the present technical solution, the mobile supporting assembly includes two third telescopic rods symmetrically and horizontally fixedly mounted on the upper side wall of the second mounting frame. The piston rod ends of the two third telescopic rods extend to one side of the second mounting frame and are fixed with an L-shaped frame. The horizontal section of the L-shaped frame is located inside the second mounting frame.

[0010] As a further improvement of the present technical solution, a plurality of pressure sensors are fixedly mounted on the horizontal section of the L-shaped frame, and a rubber pad is fixedly provided on the upper side wall of the horizontal section of the L-shaped frame, and the lower side wall of the rubber pad contacts the upper end of each pressure sensor.

[0011] As a further improvement of this technical solution, the flip clamping mechanism includes two fourth telescopic rods symmetrically fixedly arranged on the upper side walls of the frame, and the upper ends of the piston rods of the two fourth telescopic rods are fixedly provided with U-shaped frames, and the U-shaped frames are located above the horizontal section of the L-shaped frame.

[0012] As a further improvement of the present technical solution, the flip clamping mechanism also includes a fixed splint rotatably arranged inside the U-shaped frame, a stepper motor is fixedly installed on the outer wall of the U-shaped frame, the output shaft of the stepper motor rotates through one side of the U-shaped frame and is fixedly connected to the fixed splint, a movable splint is provided on one side of the fixed splint, and a fifth telescopic rod is fixedly installed between the movable splint and the fixed splint near both ends.

[0013] As a further improvement of the present technical solution, a plurality of arc grooves are provided in a transverse array on the side where the fixed splint and the movable splint are close to each other. When the movable splint is close to the fixed splint, the two arc grooves at corresponding positions together form a circular groove, and the positions of the plurality of circular grooves correspond one-to-one to the positions of the plurality of pressure sensors.

[0014] As a further improvement of the present technical solution, a soft pad is fixedly provided on the inner wall of the U-shaped frame, and the reel dust-free cloth is in contact with a side of the soft pad close to the fixed splint.

[0015] As a further improvement of the present technical solution, the reeling and unreeling mechanism includes a disk rack fixedly arranged on the outer wall of the U-shaped frame, and a reel is arranged on the disk rack via a rotating shaft. The end of the reel dust-free cloth passes through the side wall of the U-shaped frame and is wound and fixed on the reel.

[0016] As a further improvement of the present technical solution, the rewinding and unwinding mechanism also includes an extension rod horizontally slidably arranged on the lower side wall of the disc rack, an I-shaped block is fixedly arranged at one end of the extension rod, and an external plate is fixedly arranged at a position corresponding to each I-shaped block on the vertical section of the L-shaped frame, a sliding groove is opened on the external plate, and the I-shaped block is slidably arranged in the corresponding sliding groove.

[0017] As a further improvement of the present technical solution, the rewinding and unwinding mechanism also includes a gear coaxially fixedly mounted on the lower end of the reel shaft through a spline, and a plurality of tooth blocks are hingedly connected in a transverse array on the side of the extension rod close to the gear, and a stop block fixed on the extension rod is provided on the side of the tooth block away from the external plate, and a tension spring is provided on the side of the stop block away from the L-shaped frame, and the two ends of the tension spring are respectively fixedly connected to the tooth block and the extension rod, and the tension spring pulls the tooth block close to the stop block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This automated assembly platform for long-range lithium battery modules, after the fixed splint and the movable splint cooperate to clamp the battery body, drives the fixed splint to rotate through a stepper motor, and then rotates and adjusts the position of the battery body so that its positive terminal or negative terminal faces downward, and inserts it into the corresponding receiving slot to meet the requirements of the predetermined assembly method of the battery body. In the process of rotating and adjusting the position of the battery body, the end of the battery body will come into contact with the reel dust-free cloth, and the reel dust-free cloth will wipe off the dust adhering to the end of the battery body, thereby increasing the strength of the glue that fixes the battery body to the base, thereby ensuring the stability of several battery bodies after assembly.

[0020] 2. The automated assembly platform for long-range lithium battery modules has a structure that, after the end of the battery cell body contacts the reel dust-free cloth, the piston rod of the third telescopic rod extends to drive the L-shaped frame away from the second mounting frame. During this process, the L-shaped frame drives the external plate to move synchronously, and the external plate drives the I-shaped block, the extension rod and several gear blocks to move synchronously. At this time, the block prevents the gear block from rotating, causing several gear blocks to drive the gears and the reel to rotate. When several gear blocks move in the opposite direction, due to the lack of the block, the gear block will rotate and will not drive the gear to rotate, ensuring that one of the reel reels always reels the reel dust-free cloth, while the other reel always unwinds. During this process, a relative displacement occurs between the reel dust-free cloth and the battery cell body, thereby effectively wiping off the dust adhered to the end of the battery cell body, improving the cleaning effect, and avoiding the problem of reduced dust wiping effect of the reel dust-free cloth due to dust adhering to the same area for a long time.

[0045] The following drawings in the embodiments of the present invention are used to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] Example 1

[0047] See also Figure 1 As shown, the purpose of this embodiment is to provide an automated assembly platform for battery life lithium battery modules, including a frame 1, wherein a plurality of conveying silicone rollers 2 are arranged in a horizontal array near the top of the frame 1. Figure 4 , both ends of the conveying silicone roller 2 rotate through the side wall of the frame 1 and are coaxially fixed with a synchronous pulley 21 through a spline. The synchronous pulley 21 on the same side is connected to the same synchronous belt 22 for transmission. At the same time, a servo motor 23 is fixedly installed on one side of the frame 1 through a bracket. The output shaft of the servo motor 23 is coaxially fixedly connected to one of the conveying silicone rollers 2 through a coupling. When the output shaft of the servo motor 23 drives the corresponding conveying silicone roller 2 to rotate, the synchronous pulley 21 on the conveying silicone roller 2 drives the two synchronous belts 22 to operate, and the synchronous belt 22 drives the remaining synchronous pulleys 21 to rotate, thereby making several conveying silicone rollers 2 operate synchronously. In order to ensure that the synchronous belt 22 can stably drive several synchronous pulleys 21 to rotate synchronously, a synchronous belt 22 with a deeper tooth depth is selected. By increasing the degree of meshing of the teeth of the synchronous belt 22 and the synchronous pulley 21, it is ensured that the synchronous belt 22 can drive all synchronous pulleys 21 to rotate synchronously.

[0048] Reference Figure 3 , a base 3 is placed horizontally above the conveying silicone roller 2, and a plurality of accommodating grooves 31 are opened in a rectangular array on the upper side wall of the base 3. The inner diameter of the accommodating groove 31 is adapted to the outer diameter of the battery body 6. At the same time, a dispensing assembly 4 and a discharge mechanism 5 are sequentially arranged on the upper side wall of the frame 1, and the base 3 is located below the dispensing assembly 4 and the discharge mechanism 5. Two limit frames 11 are symmetrically fixed near the top of the inner wall of the frame 1. The spacing between the two limit frames 11 is adapted to the width of the base 3. The two sides of the base 3 are respectively in sliding contact with the two limit frames 11. The base 3 will not be laterally offset by the restriction of the limit frames 11. When several conveying silicone rollers 2 are running synchronously, the conveying silicone rollers 2 drive the base 3 to pass under the dispensing assembly 4 and the discharge mechanism 5 in turn. When the base 3 moves to under the dispensing assembly 4, the dispensing assembly 4 performs annular dispensing on the bottom side of each accommodating groove 31.

[0049] The structure of the dispensing component 4 is detailed below. Figure 2The dispensing assembly 4 includes a first mounting bracket 41 fixedly mounted on the upper side wall of the frame 1, and a dispensing machine 42 is fixedly mounted on the upper side wall of the first mounting bracket 41. The dispensing machine 42 has a dispensing port fixedly connected to a diverter box 43 through a hose, and a plurality of annular dispensing heads 44 are fixedly mounted in a horizontal array on the lower side wall of the diverter box 43. The positions of the plurality of annular dispensing heads 44 correspond one to one with the positions of a row of accommodating grooves 31. The initial position of the annular dispensing head 44 is located directly above the conveying silicone roller 2, and the gap between the two is greater than the thickness of the base 3 to ensure that the base 3 can move smoothly between the conveying silicone roller 2 and the annular dispensing head 44. A first telescopic rod 45 is vertically fixedly mounted between both sides of the diverter box 43 and the upper side wall of the frame 1. At the same time, an infrared sensor 12 is fixedly mounted on the inner wall of the frame 1 at a position corresponding to the dispensing assembly 4. The infrared sensor 12 is electrically connected to an external control device, and the servo motor 23, the dispensing machine 42 and the first telescopic rod 45 are electrically connected to the same external control device.

[0050] The workflow of dispensing component 4 is as follows:

[0051] When the base 3 moves to the bottom of the dispensing component 4, the base 3 will trigger the infrared sensor 12, and the infrared sensor 12 will then send an electrical signal to the control device. After receiving the signal, the control device will turn off the servo motor 23, stop the silicone roller 2 from running, and accurately position the base 3 at the current position. At this time, the outermost row of receiving grooves 31 on the base 3 are aligned with the positions of several annular dispensing heads 44 respectively. Then the control device controls the piston rod of the first telescopic rod 45 to retract, driving the diverter box 43 and the annular dispensing head 44 to move vertically downward. When the lower ends of all the annular dispensing heads 44 contact the bottom of the corresponding receiving grooves 31, the control device starts the dispensing machine 42, and the dispensing machine 42 transports glue to the inside of the diverter box 43 through a hose. As the pressure inside the diverter box 43 increases, the glue is pressed into the inside of the annular dispensing head 44 and sprayed out, thereby completing the annular dispensing at the bottom of the outermost row of receiving grooves 31.

[0052] After the dispensing is completed, the control device controls the piston rod of the first telescopic rod 45 to extend, driving the diversion box 43 and the annular dispensing head 44 to reset to the initial position, and then the control device starts the servo motor 23 again to drive the conveying silicone roller 2 to operate, and move the next row of receiving grooves 31 of the base 3 to directly below the annular dispensing head 44. Repeat the above steps to complete the annular dispensing at the bottom of each receiving groove 31 of the base 3.

[0053] The control device performs precise timing control on the start and stop of the output shaft of the servo motor 23, the telescopic movement of the piston rod of the first telescopic rod 45, and the operation of the dispensing machine 42 to ensure that the device can achieve precise annular dispensing at the bottom of each receiving slot 31. The control device is driven by a preset program. When the program detects that all receiving slots 31 have completed dispensing, the dispensing component 4 is controlled to stop running until the next base 3 triggers the infrared sensor 12 to start the program again. The timing control of the control device is an existing mature technology, so it will not be described here.

[0054] When the silicone roller 2 moves the base 3 on which the dispensing is completed to the right below the discharge mechanism 5, the discharge mechanism 5 automatically places the ends of the plurality of battery cell bodies 6 into the corresponding receiving grooves 31. The structure of the discharge mechanism 5 is detailed below. Figure 5 The discharge mechanism 5 includes a second mounting frame 51 fixedly arranged on the upper side wall of the frame 1, and a blanking assembly 52 is provided on the upper side wall of the second mounting frame 51. The blanking assembly 52 is used to output a plurality of battery cell bodies 6 in a single row, and the second mounting frame 51 is provided with a movable receiving assembly 53 for receiving the battery cell bodies 6 output by the blanking assembly 52. ​​A flip clamping mechanism 54 is provided inside the second mounting frame 51, and a reel dust-free cloth 7 is provided on the flip clamping mechanism 54. Both ends of the reel dust-free cloth 7 are provided with a winding and unwinding mechanism 55.

[0055] The structure of the mobile receiving assembly 53 is detailed below. Figure 6 and Figure 9 The mobile supporting component 53 includes two third telescopic rods 531 symmetrically and horizontally fixedly mounted on the upper side wall of the second mounting frame 51. The piston rod ends of the two third telescopic rods 531 extend to one side of the second mounting frame 51 and are fixed with an L-shaped frame 532. The L-shaped frame 532 is located on the side of the second mounting frame 51 close to the dispensing component 4. The L-shaped frame 532 consists of a vertical section fixed to the piston rod end of the third telescopic rod 531 and a horizontal section fixed to the lower side of the vertical section. The horizontal section of the L-shaped frame 532 is located inside the second mounting frame 51, and the horizontal section of the L-shaped frame 532 is located above the base 3. Several pressure sensors 535 are fixedly mounted on the horizontal section of the L-shaped frame 532, and a rubber pad 536 is fixedly provided on the upper side wall of the horizontal section of the L-shaped frame 532. The lower side wall of the rubber pad 536 contacts the upper end of each pressure sensor 535.

[0056] The structure of the blanking assembly 52 is detailed below. Figure 7 and Figure 8The material unloading assembly 52 includes a material box 521 fixedly mounted on the upper side wall of the second mounting frame 51. A through slot 522 is provided at the bottom of the material box 521 and the top of the second mounting frame 51 at a position corresponding to each pressure sensor 535. When the L-shaped frame 532 is in the initial position, the rubber pad 536 is located directly below the through slot 522. A guide frame 523 is fixedly provided inside the material box 521. A plurality of guide slots 526 are provided in a transverse array on one side of the guide frame 523. The ends of the plurality of guide slots 526 correspond to the positions of the plurality of through slots 522 one by one. The middle portion of one side of the guide frame 523 is fixedly provided with a plurality of guide slots 526. A movable groove 527 is provided at the intermediate position, and the movable groove 527 is connected to several guide grooves 526. At the same time, a second telescopic rod 524 is horizontally fixedly installed on one side of the material box 521. The piston rod end of the second telescopic rod 524 slides through one side of the material box 521 and is fixedly provided with a push plate 525. The push plate 525 is slidably set inside the movable groove 527. Several battery cell bodies 6 are placed in a horizontal array inside the several guide grooves 526, and the battery cell bodies 6 are located between the push plate 525 and the through groove 522. The positive end parts of the battery cell bodies 6 are uniformly located at the top, and the negative end parts are uniformly located at the bottom.

[0057] The structure of the flip clamping mechanism 54 is detailed below. Figure 10 The flip clamping mechanism 54 includes two fourth telescopic rods 541 symmetrically fixedly arranged on the upper side wall of the frame 1, and a U-shaped frame 542 is fixedly arranged on the upper end of the piston rod of the two fourth telescopic rods 541. The U-shaped frame 542 consists of two short rods parallel to each other and a long rod fixed to one end of the two short rods. The U-shaped frame 542 is located above the horizontal section of the L-shaped frame 532. The flip clamping mechanism 54 also includes a fixed splint 544 rotatably arranged inside the U-shaped frame 542. A stepper motor 543 is fixedly installed on the outer wall of the U-shaped frame 542. The output shaft of the stepper motor 543 rotates through one side of the U-shaped frame 542 and is fixedly connected to the fixed splint 544. The fixed splint A movable splint 545 is provided on one side of 544, and a fifth telescopic rod 546 is fixedly installed between the movable splint 545 and the fixed splint 544 near both ends. A plurality of arc grooves 547 are provided in a transverse array on the side where the fixed splint 544 and the movable splint 545 are close to each other. When the movable splint 545 is close to the fixed splint 544, the two arc grooves 547 at corresponding positions together form a circular groove. The positions of the plurality of circular grooves correspond one-to-one to the positions of the plurality of pressure sensors 535, and the positions of the plurality of circular grooves correspond one-to-one to the positions of the plurality of through grooves 522 respectively. The circular groove is located between the material box 521 and the rubber pad 536.

[0058] The third telescopic rod 531 , the pressure sensor 535 , the second telescopic rod 524 , the fourth telescopic rod 541 , the stepping motor 543 and the fifth telescopic rod 546 are electrically connected to the same external control device.

[0059] An infrared sensor 12 is also installed at a position inside the frame 1 corresponding to the discharge mechanism 5. The infrared sensor 12 is also electrically connected to an external control device. When the silicone rubber roller 2 transports the base 3 after dispensing glue to the bottom of the second mounting frame 51, the base 3 will trigger the infrared sensor 12, and the infrared sensor 12 will immediately send an electrical signal to the control device. After receiving the signal, the control device turns off the servo motor 23, stops the silicone rubber roller 2 from running, and accurately positions the base 3 at the current position. At this time, the position of the outermost row of accommodating grooves 31 on the base 3 corresponds one-to-one to the positions of several through grooves 522.

[0060] At this time, the external control device controls the piston rod of the second telescopic rod 524 to extend, driving the push plate 525 to slide along the inner wall of the movable groove 527 and move toward the direction close to the through groove 522. The push plate 525 pushes the battery cell body 6 inside each guide groove 526 toward the corresponding through groove 522 at the same time. The length of the extended piston rod of the second telescopic rod 524 is precisely controlled to push the row of battery cell bodies 6 closest to the through groove 522 to the top of the through groove 522. Under the action of gravity, the battery cell body 6 passes through the through groove 522 and falls to the upper side wall of the rubber pad 536 of the horizontal section of the L-shaped frame 532 below, thereby outputting the single row of battery cell bodies 6 to the top of the movable receiving assembly 53.

[0061] When the battery cell body 6 collides with the rubber pad 536, the rubber pad 536 undergoes elastic deformation to absorb part of the impact force, thereby preventing the battery cell body 6 from being damaged by the impact force. When the battery cell body 6 is stably placed on the upper side wall of the rubber pad 536 under the support of the arc groove 547, the mobile receiving assembly 53 receives the battery cell body 6, and the battery cell body 6 applies pressure to the pressure sensor 535. The pressure sensor 535 that detects the predetermined threshold sends an electrical signal to the control device, causing the control device to control the piston rod of the fifth telescopic rod 546 to retract and drive ... The movable splint 545 is close to the fixed splint 544. When the two arc grooves 547 at corresponding positions form a circular groove together, the two arc grooves 547 are in close contact with the middle position of the circumferential side wall of the battery cell body 6, thereby realizing the synchronous clamping and fixation of the single-row battery cell body 6. Then the control device controls the output shaft of the stepper motor 543 to drive the fixed splint 544 to rotate, so that the position of the battery cell body 6 can be rotated and adjusted while the movable splint 545 and the fixed splint 544 cooperate to clamp and fix the battery cell body 6, thereby adjusting the swing angle of the battery cell body 6.

[0062] It should be noted that the number of revolutions of the fixed splint 544 driven by the output shaft of the stepper motor 543 is strictly limited to a predetermined number of revolutions in the forward and reverse directions. This limitation is intended to prevent the fixed splint 544 from rotating too many times in a single direction, causing the external wires of the fifth telescopic rod 546 to be entangled on the fixed splint 544, thereby preventing the wires from being pulled off and ensuring the safety of the device.

[0063] The structure of the rewinding and unwinding mechanism 55 is detailed below. Figure 11 and Figure 12 The unwinding and rewinding mechanism 55 includes a disk rack 558 fixedly arranged on the outer side wall of the U-shaped frame 542, and a reel 551 is arranged on the disk rack 558 by rotating the rotating shaft. The end of the reel dust-free cloth 7 passes through the side wall of the U-shaped frame 542 and is wound and fixed on the reel 551, that is, the two ends of the reel dust-free cloth 7 are respectively wound and fixed on the two reel disks 551. The reel 551 is a large disk structure, and the reel dust-free cloth 7 on the reel 551 can be used for a long time. The unwinding and rewinding mechanism 55 also includes an extension rod 553 horizontally slidably arranged on the lower side wall of the disk rack 558, and one end of the extension rod 553 is fixedly provided with an I-shaped block 557. The position corresponding to each I-shaped block 557 on the vertical section of the L-shaped frame 532 They are all fixed with an external plate 533, and a slide groove 534 is opened on the external plate 533. The I-shaped block 557 is slidably set in the corresponding slide groove 534. The reeling and unreeling mechanism 55 also includes a gear 552 coaxially fixedly installed at the lower end of the rotating shaft of the reel 551 through a spline. A plurality of tooth blocks 554 are hingedly connected in a transverse array on the side of the extension rod 553 close to the gear 552. A stop block 555 fixed on the extension rod 553 is provided on the side of the tooth block 554 away from the external plate 533. A tension spring 556 is provided on the side of the stop block 555 away from the L-shaped frame 532. The two ends of the tension spring 556 are respectively fixed to the tooth block 554 and the extension rod 553. The tension spring 556 pulls the tooth block 554 close to the stop block 555.

[0064] A soft pad 71 is fixed on the inner wall of the long rod of the U-shaped frame 542, and the reel dust-free cloth 7 is in contact with the soft pad 71 on the side close to the fixed clamp 544, and the reel dust-free cloth 7 is in a taut state. When the fixed clamp 544 is rotated to a vertical state, the distance between the fixed clamp 544 and the reel dust-free cloth 7 is the same as the distance between the fixed clamp 544 and the rubber pad 536 when the fixed clamp 544 is set horizontally, and the fixed clamp 544 clamps the middle position of the battery cell body 6. This design ensures that when the battery cell body 6 is rotated to a horizontal state, the end of the battery cell body 6 is in contact with one side of the reel dust-free cloth 7. At this time, the control device controls the piston rod of the third telescopic rod 531 to extend and drive the L-shaped frame 532 away from the second mounting frame 51, so that the horizontal section of the L-shaped frame 532 moves out from directly below the battery cell body 6. During this process, the L-shaped frame 532 drives the external plate 533 to move synchronously, and the external plate 533 drives the I-shaped block 557 and the extension rod 553 moves synchronously. At this time, the block 555 prevents the tooth block 554 from rotating in the direction away from the external plate 533, so that the tooth block 554 remains in a state perpendicular to the extension rod 553, so that the tooth block 554 remains engaged with the gear 552. At this time, when several tooth blocks 554 move, the gear 552 and the reel 551 are driven to rotate. During the movement of the L-shaped frame 532, the two reel-up and reel-down mechanisms 55 are driven, so that the two reel-up and reel-down mechanisms 55 respectively reel in and unreel the reel dust-free cloth 7: the two reel-up and reel-down mechanisms 551 rotate synchronously in opposite directions, one of the reel-up and reel-down mechanisms 551 reels the reel dust-free cloth 7, and the other reel-up and reel-down mechanisms 551 unreel the reel dust-free cloth 7. The lengths of the reel dust-free cloth 7 reeled and unreeled by the two reel-up and reel-down mechanisms 551 are the same, so that the reel dust-free cloth 7 remains taut. During this process, the reel dust-free cloth 7 and the battery cell body 6 are relatively displaced, thereby wiping off the dust adhered to the end of the battery cell body 6.

[0065] When the horizontal section of the L-shaped frame 532 is completely removed from the bottom of the battery cell body 6 and stops moving, the reel dust-free cloth 7 stops winding and ends wiping the end of the battery cell body 6. Then the stepper motor 543 rotates the battery cell body 6 to a vertical state, so that the wiped end of the battery cell body 6 is rotated to a position corresponding to the receiving groove 31. It should be emphasized that when the positive end of the battery cell body 6 needs to be inserted into the receiving groove 31, the stepper motor 543 drives the battery cell body 6 to rotate 180 degrees so that the positive end of the battery cell body 6 faces downward. When the negative end of the battery cell body 6 needs to be inserted into the receiving groove 31, the stepper motor 543 drives the battery cell body 6 to rotate 180 degrees. First, rotate 90 degrees to make the negative pole of the battery cell body 6 contact with the reel dust-free cloth 7. After the dust is wiped, the stepper motor 543 drives the battery cell body 6 to rotate 90 degrees in the opposite direction so that the negative end of the battery cell body 6 faces downward. Then the piston rod of the fourth telescopic rod 541 retracts to drive the U-shaped frame 542, the fixed splint 544, the movable splint 545 and the battery cell body 6 to move vertically downward. During this process, the I-shaped block 557 slides in the corresponding slide groove 534 until the wiped end of the battery cell body 6 is inserted into the corresponding receiving groove 31 on the base 3. The end of the battery cell body 6 is bonded and fixed in the receiving groove 31 by glue to complete the assembly of the single-row battery cell body 6.

[0066] When the fixed clamp 544 and the movable clamp 545 cooperate to clamp the battery cell body 6, the distance between the two ends of the battery cell body 6 and the fixed clamp 544 is equal. By controlling the angle of the output shaft of the stepper motor 543 to rotate the battery cell body 6, both ends of the battery cell body 6 can be rotated to a position in contact with the reel dust-free cloth 7, and the two ends of the battery cell body 6 can be wiped and cleaned. At the same time, the position of the battery cell body 6 can be adjusted so that its positive end or negative end faces downward, so that it can be inserted into the corresponding accommodating groove 31 to meet the requirements of the predetermined assembly method of the battery cell body 6.

[0067] After completing the assembly of the single-row battery cell body 6, the piston rod of the fifth telescopic rod 546 extends to drive the movable splint 545 away from the fixed splint 544, releasing the clamping fixation of the two on the battery cell body 6, and then the piston rod of the fourth telescopic rod 541 extends to drive the U-shaped frame 542, the movable splint 545 and the fixed splint 544 to move up and reset, and then the output shaft of the stepper motor 543 rotates in the opposite direction of the previous rotation angle, rotating the movable splint 545 and the fixed splint 544 to reset, so as to avoid the external wires of the fifth telescopic rod 546 from being wrapped around the fixed splint 544 for multiple turns, creating the risk of the wires being pulled apart.

[0068] Then the piston rod of the third telescopic rod 531 retracts and drives the L-shaped frame 532 to reset, that is, the horizontal section of the L-shaped frame 532 moves to the bottom of the fixed clamping plate 544. During this process, the external plate 533 drives the I-shaped block 557 and the extension rod 553 to move synchronously. At this time, the gear 552 pushes the tooth block 554 to rotate away from the stop block 555, causing the tension spring 556 to elastically stretch, so that the tooth block 554 will not mesh with the gear 552, thereby driving the gear 552 and the winding disk 551 to rotate. When the tooth block 554 is out of contact with the gear 552, the tension spring 556 rebounds and drives the tooth block 554 to rotate and reset, so it will not affect the normal engagement of the tooth block 554 with the gear 552 when it moves in the opposite direction. In this way, one of the winding disks 551 always rewinds the reel dust-free cloth 7, and the other winding disk 551 always unwinds the reel dust-free cloth 7, so that the reel dust-free cloth 7 that contacts the end of the battery cell body 6 can be continuously updated, ensuring the cleaning effect of the reel dust-free cloth 7 on the end of the battery cell body 6.

[0069] After the conveying silicone roller 2 moves the next row of receiving grooves 31 on the base 3 to directly below the through groove 522 under the program control of the control device, the above steps can be repeated to assemble the next row of battery cell bodies 6 into the corresponding receiving grooves 31. The second telescopic rod 524, the third telescopic rod 531, the pressure sensor 535, the fourth telescopic rod 541, the stepping motor 543 and the fifth telescopic rod 546 are all precisely timed by the external control device to ensure that the device can assemble the end of each battery cell body 6 into the corresponding receiving groove 31 in a predetermined assembly method. The control device is driven by a preset program. After the battery cell body 6 is assembled in each receiving groove 31, the conveying silicone roller 2 moves the base 3 out of the second mounting frame 51 and controls the discharge mechanism 5 to stop running until the next base 3 triggers the infrared sensor 12 to start the program again. The timing control of the control device is an existing mature technology and will not be described in detail here.
