Description

Technical Field

[0001] The present invention belongs to the technical field of sodium-ion battery assembly, and in particular relates to an assembly machine for the processing and manufacturing of sodium-ion batteries. Background Art

[0002] A sodium-ion battery is a new type of battery technology, similar to a lithium-ion battery, but it uses sodium ions as the main charge carriers, and its working principle is based on the insertion and extraction of sodium ions between the positive and negative electrodes. During charging, sodium ions are released from the positive electrode material, migrate through the electrolyte to the negative electrode, and are inserted into the negative electrode; during discharging, sodium ions are extracted from the negative electrode and migrate back to the positive electrode.

[0003] In the manufacturing and processing of sodium-ion batteries, assembly is a crucial link. Since a sodium-ion battery includes multiple components such as a positive electrode, a negative electrode, an electrolyte, and a separator, it is necessary to ensure the precise alignment of these components during assembly to avoid battery short circuits and poor performance. At the same time, during the assembly process, it is also necessary to ensure effective contact between the battery pack, the protective case, and the cover plate to ensure the high energy density, charge and discharge efficiency, and cycle life of the battery.

[0004] However, when the existing assembly machines assemble sodium-ion batteries, the following technical problems usually exist:

[0005] Before assembling the battery pack and the cover plate, it is usually necessary to process the wiring to avoid the wiring being wound or deformed, resulting in fatigue of the internal material of the wiring and increasing the risk of breakage. In the prior art, the process of processing the wiring usually involves first pressing the wiring, and after the pressing is completed, driving a wire pulling device to slide on the wiring for wire pulling. In this method, the pressing process and the wire pulling process need to be driven by two different driving sources, resulting in the inability to continuously process the wiring, reducing the continuity of the assembly process and the assembly efficiency;

[0006] During the assembly process of the cover plate, due to the contact between the cover plate and the wiring and the gravitational force of the wiring itself, the wiring is prone to bending, which in turn causes the metal part of the wiring to contact other components of the battery, increasing the risk of short circuit, not only reducing the performance and service life of the battery, but also possibly causing safety accidents such as fires or explosions. Summary of the Invention

[0007] The object of the present invention is to provide an assembly machine for the processing and manufacturing of sodium-ion batteries, which first drives two clamping arc blocks to rotate to fit the wiring of the sodium-ion battery, and then keeps the clamping arc blocks clamping the wiring and pulls the smoothing plate to move upward in the vertical direction to realize the continuous progress of the pressing and wire pulling operations.

[0020] Compared with the existing technology, the advantages of this assembly machine for processing and manufacturing sodium-ion batteries are as follows:

[0021] 1. By setting the clamping and smoothing mechanism, before assembling the cover plate onto the battery pack and the protective case, the first motor drives the screw to rotate, thereby driving the lifting plate to displace vertically upward from bottom to top. During this process, the rack is first driven to displace horizontally on the smoothing plate, so that the two clamping arc blocks rotate to fit the wiring of the sodium-ion battery. Subsequently, the clamping of the wiring by the clamping arc blocks is maintained and the smoothing plate is pulled to displace vertically upward, so as to perform the smoothing process of the wiring of the battery pack from bottom to top, realizing the continuous progress of the wire pressing and wire pulling operations, improving the work continuity, enhancing the assembly efficiency of the battery pack, and saving the driving source and the energy consumed in processing at the same time.

[0022] 2. By setting the anti-bending mechanism, after the wire pulling is completed, the first motor drives the screw to rotate in the reverse direction, so that the lifting plate displaces vertically downward. At the same time, the cover plate is driven by the assembly mechanism to displace downward to align with the wiring. When the lifting plate and the cover plate move down to expose the top of the wiring, the pressing plate contacts the plane above the trapezoidal abutting block, so that the conductive sheets on the pressing plate and the trapezoidal abutting block are in contact with each other. The elastic force of the electromagnetic spring drives the ends of the two V-shaped rods close to the wiring to approach each other until the pinching arc block closely adheres to the wiring, pinching the upper end of the wiring tightly. At the same time, the pressing plate is limited above the trapezoidal abutting block during the assembly process, keeping the upper end of the wiring always on the same horizontal line during the assembly process, avoiding the wiring from being bent during the assembly process, resulting in the metal part of the wiring contacting other components of the battery, improving the performance and service life of the battery, and avoiding the occurrence of safety accidents.

[0023] 3. The present invention is provided with an air purification mechanism. During continuous assembly work, the annular piston plate makes reciprocating vertical displacements within the air extraction box, thereby continuously pumping external air into the annular filter box through the air inlet pipe. The filter screen arranged inside the annular filter box filters dust and impurities in the air, and the filtered air is transported to the annular air extraction box through the air delivery pipe and discharged to the periphery of the assembly position through the exhaust port, purifying the air around the assembly position to prevent dust, oil stains and other impurities from falling between the battery pack and the cover plate, entering the battery and affecting its performance.

[0024] 4. The present invention is provided with a rotation mechanism. When there is a relative displacement between the lifting rod in the telescopic rod and the fixed cylinder, the lifting rod can rotate, enabling the rotating ring to drive the air inlet pipe to perform a circular motion, adjusting the air pumping position of the external air, so that the air in all directions around the assembly position can be pumped into the annular filter box for filtration, improving the purification effect on the external air and further preventing dust and impurities from affecting the battery performance.

Detailed implementation mode

[0034] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0035] Embodiment: Refer to Figures 1 to 8 , an assembly machine for the processing and manufacturing of sodium-ion batteries, including a body 1;

[0036] Two sets of symmetrically arranged clamping and straightening mechanisms 2 are used to clamp the battery wiring and drive the clamped position upward to straighten the battery wiring. Each clamping and straightening mechanism 2 includes a fixing plate 21 arranged above the machine body 1. The fixing plate 21 is fixedly connected to the upper end of the machine body 1 through a first support rod. A screw rod 22 is rotatably connected to the upper end of the fixing plate 21. A lifting plate 23 that displaces vertically is threadedly connected to the screw rod 22. A U-shaped plate 24 is fixedly connected to the side wall of the fixing plate 21. A first motor 25 for driving the screw rod 22 is fixedly connected to the top of the U-shaped plate 24. Two first hinge seats 26 are provided on the side wall of the lifting plate 23. Two straightening plates 27 are slidably connected to the side wall of the fixing plate 21 in the vertical direction. A rack 28 is slidably connected to each straightening plate 27 in the horizontal direction. A second hinge seat 29 is provided at the upper end of each rack 28. Connecting rods 210 are provided between the two first hinge seats 26 and the two second hinge seats 29. A rotating rod 211 is rotatably connected to each straightening plate 27. A first gear 212 meshing with the corresponding rack 28 is fixedly connected to each rotating rod 211. An extension rod 213 is fixedly connected to each rotating rod 211. A clamping arc block 214 is fixedly connected to the end of each extension rod 213 away from the rotating rod 211;

[0037] Specifically, two limiting rods 215 are fixedly connected to the fixing plate 21. The two limiting rods 215 penetrate and are slidably connected to the lifting plate 23. The lifting plate 23 can be limited by the limiting rods 215, so that the lifting plate 23 can only displace vertically in the vertical direction when the screw rod 22 rotates.

[0038] Specifically, a first chute arranged horizontally and a second chute arranged vertically are provided on the straightening plate 27 and the fixing plate 21, which are respectively used to limit the sliding of the rack 28 and the straightening plate 27, ensuring that the rack 28 first displaces horizontally relative to the straightening plate 27, and then the straightening plate 27 displaces vertically relative to the fixing plate 21.

[0039] In view of the problem that in the prior art, wire pressing treatment needs to be carried out on the wiring first, and after the wire pressing is completed, the wire pulling device is driven to slide on the wiring for wire pulling treatment. In this way, the wire pressing treatment and the wire pulling treatment need to be driven by two different driving sources, resulting in the inability to continuously carry out the treatment process of the wiring, reducing the continuity of the assembly process and the assembly efficiency. The present invention solves this problem by providing a clamping and smoothing mechanism 2. Before assembling the cover plate on the battery pack and the protective case, the first motor 25 is used to drive the screw rod 22 to rotate, thereby driving the lifting plate 23 to displace upward in the vertical direction from bottom to top. During this process, under the action of the first hinge seat 26, the second hinge seat 29 and the connecting rod 210, the rack 28 is first driven to displace horizontally on the smoothing plate 27, so as to drive the rotating rod 211, the extension rod 213 and the clamping arc block 214 to rotate under the action of the first gear 212, so that the two clamping arc blocks 214 rotate to fit the wiring of the sodium ion battery. Subsequently, since the rack 28 is displaced to the farthest end, the continuous upward movement of the lifting plate 23 will keep the rack 28 at the farthest end and pull the smoothing plate 27 to displace upward in the vertical direction, so as to carry out the smoothing treatment of the wiring of the battery pack from bottom to top, realizing the continuous progress of the wire pressing and wire pulling work, improving the working continuity, improving the assembly efficiency of the battery pack, and saving the driving source and the energy consumed in processing at the same time.

[0040] An assembling mechanism 3 for assembling the cover plate on the upper ends of the battery pack and the protective case. The assembling mechanism 3 includes a cover containing frame 31 fixedly connected above the machine body 1 and a picking and placing component arranged above the cover containing frame 31.

[0041] Specifically, the picking and placing component includes a guide rail 32 arranged above the cover containing frame 31. The guide rail 32 is fixedly connected to the upper end of the machine body 1 through a second support rod. A slider 33 is slidably connected in the horizontal direction inside the guide rail 32. A second motor 34 for driving the slider 33 is fixedly connected to an outer wall of one side of the guide rail 32. More specifically, a lead screw is fixedly connected inside the guide rail 32. The slider 33 is threadedly connected to the lead screw, and the output end of the second motor 34 is fixedly connected to the lead screw. A support plate 35 is fixedly connected to the bottom end of the slider 33. Two electric push rods 36 are fixedly connected to the lower end of the support plate 35. Suction cups 37 are fixedly connected to the output ends of the two electric push rods 36. A micro air extraction pump and an exhaust nozzle with an opening and closing valve installed inside are arranged above each suction cup 37.

[0042] During actual assembly, keep the slider 33 and the support plate 35 directly above the lid frame 31. Drive the suction cup 37 to move downward through the electric push rod 36, so that the suction cup 37 is pressed against the upper wall of the cover sheet. Subsequently, the air between the suction cup 37 and the upper wall of the cover sheet is pumped out by the micro air pump, so that the cover sheet can be adsorbed on the suction cup 37 under negative pressure. After the electric push rod 36 drives the suction cup 37 to move upward to lift the cover sheet, drive the screw rod to rotate through the second motor 34, and drive the slider 33 and the support plate 35 to move to directly above the battery pack and the protective case. After the electric push rod 36 moves the suction cup 37 downward to the designated position, open the opening and closing valve in the exhaust nozzle, and the cover sheet can be separated from the suction cup 37, realizing the assembly work of the cover sheet with the battery pack and the protective case.

[0043] An anti-bending mechanism 4 is provided between the fixing plate 21 and the two smoothing plates 27, which is used to prevent the wiring from bending during the assembly of the cover sheet. The anti-bending mechanism 4 includes a guiding plate 41 fixedly connected to the fixing plate 21. A connecting plate 42 is fixedly connected between the two smoothing plates 27. The upper end of the connecting plate 42 is fixedly connected with a telescopic rod 43. A pressing plate 44 is arranged on the telescopic rod 43. The pressing plate 44 is slidably connected to the side wall of the guiding plate 41 in the vertical direction. A trapezoidal abutting block 45 that cooperates with the pressing plate 44 is slidably connected through the side wall of the guiding plate 41 near the upper end. The part of the trapezoidal abutting block 45 extending to the other side of the guiding plate 41 is fixedly connected with a reset plate 46. Two first reset springs 47 are arranged between the reset plate 46 and the side wall of the guiding plate 41. Conductive sheets 48 are arranged at the same positions on the lower wall of the pressing plate 44 and the upper wall of the trapezoidal abutting block 45. The upper end of the pressing plate 44 is fixedly connected with a fixed shaft 49. Two V-shaped rods 410 are rotatably connected to the fixed shaft 49. A pinching arc block 411 is arranged on each V-shaped rod 410. An electromagnetic spring 412 is elastically connected between the two V-shaped rods 410. The electromagnetic spring 412 is connected in series with the power supply device inside the machine body 1 through two conductive sheets 48. A tension spring 413 is elastically connected between the two V-shaped rods 410 on the side far from the electromagnetic spring 412.

[0044] Specifically, the telescopic rod 43 includes a fixed cylinder 415 fixedly arranged at the upper end of the connecting plate 42 and a lifting rod 414 arranged inside the fixed cylinder 415. The lifting rod 414 is rotatably connected through the pressing plate 44. The arrangement of the lifting rod 414 and the fixed cylinder 415 enables a relative displacement to occur between the pinching arc block 411 on the upper side and the clamping arc block 214 on the lower side. Thus, when the clamping arc block 214 and the cover sheet move downward synchronously, the pinching arc block 411 always pinches the upper end of the sodium-ion battery wiring.

[0045] In view of the problem that in the prior art, during the assembly process of the cover plate, due to the contact between the cover plate and the wiring and the gravity of the wiring itself, the wiring is prone to bending. The present invention sets an anti-bending mechanism 4. After the wire drawing is completed, the first motor 25 drives the screw rod 22 to rotate in the reverse direction, so that the lifting plate 23 moves downward from top to bottom. At the same time, the electric push rod 36 in the assembly mechanism 3 drives the cover plate to move downward and align with the wiring. When the lifting plate 23 and the cover plate move down to expose the top end of the wiring, the pressing plate 44 contacts the plane above the trapezoidal abutting block 45 (during the process of the lifting plate 23 moving upward from bottom to top, the pressing plate 44 abuts against the inclined surface on the side of the trapezoidal abutting block 45, which can push the trapezoidal abutting block 45 to slide, so that when the pressing plate 44 moves upward, there will be no movement interference phenomenon. After the pressing plate 44 moves to above the trapezoidal abutting block 45, the trapezoidal abutting block 45 pops out under the action of the first return spring 47, ensuring that when the pressing plate 44 moves downward, it can abut against the trapezoidal abutting block 45 and the pressing plate 44 is restricted by the plane above the trapezoidal abutting block 45), so that the conductive sheets 48 on the pressing plate 44 and the trapezoidal abutting block 45 are in contact with each other, so that the electromagnetic spring 412, the conductive sheet 48 and the power supply device form a circuit, and the electromagnetic spring 412 is turned on. Since the elastic force of the electromagnetic spring 412 is much greater than the elastic force of the tension spring 413, the ends of the two V-shaped rods 410 close to the wiring can be driven to approach each other until the clamping arc block 411 tightly adheres to the wiring, clamping and squeezing the upper end of the wiring. At the same time, due to the abutment of the trapezoidal abutting block 45 against the pressing plate 44 and the telescopic performance of the telescopic rod 43, the pressing plate 44 can be limited above the trapezoidal abutting block 45 during the assembly process, keeping the upper end of the wiring always on the same horizontal line during the assembly process, avoiding the bending of the wiring during the assembly process, preventing the metal part of the wiring from contacting other components of the battery, improving the performance and service life of the battery, and avoiding the occurrence of safety accidents.

[0046] The air purification mechanism 5 is provided at the position of the machine body 1 above the assembly mechanism 3. The air purification mechanism 5 includes an annular filter box 51 arranged above the guide rail 32. The annular filter box 51 is fixedly connected to the upper end of the machine body 1 through a third support rod. The lower ends of multiple wire-straightening plates 27 are fixedly connected with an annular air extraction box 52. An annular piston plate 53 is hermetically slidably connected in the annular air extraction box 52. The bottom end of the lifting rod 414 is fixedly connected with a connecting rod 54. The bottom end of the connecting rod 54 is rotatably connected to the upper end of the annular piston plate 53. An air delivery pipe 55 is communicated between the annular filter box 51 and the annular air extraction box 52. A rotating ring 56 is penetrated through the upper wall of the annular air extraction box 52. The rotating ring 56 is circumferentially slidably connected to the upper wall of the annular air extraction box 52. An air inlet pipe 57 communicating the outside and the inside of the annular filter box 51 is penetrated through the rotating ring 56. An exhaust port is opened at the upper end of the annular air extraction box 52. One-way valves are provided in both the air delivery pipe 55 and the exhaust port.

[0047] Specifically, the one-way valve is arranged such that when the annular piston plate 53 reciprocates vertically within the annular air extraction box 52, only the air purified in the annular filtration box 51 can be pumped into the annular air extraction box 52 through the air delivery pipe 55, and the air in the annular air extraction box 52 is discharged to the periphery of the assembly position, avoiding air backflow during continuous transportation and ensuring the purification effect of the air around the assembly position.

[0048] Specifically, the rod body of the lifting rod 414 is provided with external threads, and the inner wall of the fixed cylinder 415 is provided with internal threads matching the external threads. The mutual cooperation between the external threads and the internal threads enables the lifting rod 414 to rotate when the lifting rod 414 displaces relative to the fixed cylinder 415.

[0049] To prevent impurities such as dust and oil from entering the battery during the assembly process and affecting the battery performance, the present invention sets up an air purification mechanism 5. During the assembly process, the resistance of the trapezoidal abutting block 45 against the pressing plate 44 will cause the lifting rod 414 within the telescopic rod 43 to displace relative to the fixed cylinder 415, and then drive the annular piston plate 53 to displace upward within the annular air extraction box 52 through the connecting rod 54. After the assembly is completed, it is necessary to press the trapezoidal abutting block 45 to enable the pressing plate 44 to press and reset under the action of gravity to ensure the assembly work for the next sodium ion battery. At this time, the annular piston plate 53 displaces downward within the annular air extraction box 52. The continuous assembly work causes the annular piston plate 53 to reciprocate vertically within the annular air extraction box 52, thereby continuously pumping external air into the annular filtration box 51 through the air inlet pipe 57, filtering the dust impurities in the air through the filter screen arranged inside the annular filtration box 51, and conveying the filtered air to the annular air extraction box 52 through the air delivery pipe 55, and discharging it to the periphery of the assembly position through the exhaust port to purify the air around the assembly and prevent impurities such as dust and oil from falling between the battery pack and the cover plate.

[0050] A rotating mechanism 6 is arranged on the periphery of the annular filtration box 51 for driving the air inlet pipe 57 to perform circular motion to improve the purification effect on the surrounding air. The rotating mechanism 6 includes a toothed ring 61 rotatably connected to the outer wall of the periphery of the annular filtration box 51. The toothed ring 61 is fixedly connected to the rotating ring 56. The upper end of each U-shaped plate 24 is rotatably connected to a transmission rod 62 through a mounting block. The top end of each transmission rod 62 is fixedly connected to a second gear 63 meshing with the toothed ring 61. The bottom end of each transmission rod 62 is fixedly connected to a third gear 64. The top end of each lifting rod 414 is fixedly connected to a fourth gear 65 meshing with the third gear 64.

[0051] Specifically, a fixed block 7 is fixedly connected to the upper end of the annular filter box 51, a moving block 71 is fixedly connected to the outer wall of the rotating ring 56, a second return spring 72 is arranged between the fixed block 7 and the moving block 71, and the elastic force of the second return spring 72 can rotate the rotating ring 56 and the air inlet pipe 57 back to the initial position after each battery assembly process, ensuring the purification effect of the surrounding air during the next battery assembly.

[0052] To improve the comprehensiveness of air purification, the present invention is provided with a rotating mechanism 6. When a relative displacement occurs between the lifting rod 414 in the telescopic rod 43 and the fixed cylinder 415, the external thread on the outer wall of the lifting rod 414 will slide along the internal thread on the inner wall of the fixed cylinder 415, so that the lifting rod 414 can rotate while displacing. Furthermore, the third gear 64 and the fourth gear 65 drive the transmission rod 62 to rotate, and further drive the toothed ring 61 to rotate through the second gear 63, so that the rotating ring 56 drives the air inlet pipe 57 to perform a circular motion, adjusting the pumping position of the external air, enabling the air in all directions around the assembly position to be pumped into the annular filter box 51 for filtration, improving the purification effect of the external air, and further avoiding the influence of dust and impurities on the battery performance.

[0053] The functional principle of the present invention can be elaborated through the following operation methods:

[0054] During actual assembly, keep the slider 33 and the support plate 35 directly above the lid frame 31. Drive the suction cup 37 to displace downward through the electric push rod 36, so that the suction cup 37 is pressed against the upper wall of the cover sheet. Subsequently, the air between the suction cup 37 and the upper wall of the cover sheet is pumped out through the micro air pump, so that the cover sheet can be adsorbed on the suction cup 37 under negative pressure. After the electric push rod 36 drives the suction cup 37 to displace upward to lift the cover sheet, drive the screw rod to rotate through the second motor 34, and drive the slider 33 and the support plate 35 to displace directly above the battery pack and the protective case;

[0055] Drive the screw rod 22 to rotate through the first motor 25, and drive the lifting plate 23 to displace upward along the vertical direction from bottom to top. During this process, under the action of the first hinge seat 26, the second hinge seat 29 and the connecting rod 210, the rack 28 will be first driven to displace horizontally along the smoothing plate 27, so that the rotating rod 211, the extension rod 213 and the clamping arc block 214 rotate under the action of the first gear 212, so that the two clamping arc blocks 214 rotate to fit the wiring of the sodium ion battery. Subsequently, when the rack 28 displaces to the farthest end, the continuous upward movement of the lifting plate 23 will keep the rack 28 at the farthest end and pull the smoothing plate 27 to displace upward along the vertical direction, so as to smooth the wiring of the battery pack from bottom to top;

[0056] The screw rod 22 is driven to rotate reversely by the first motor 25, so that the lifting plate 23 is displaced from top to bottom. At the same time, the electric push rod 36 in the assembling mechanism 3 drives the cover plate to displace downward to align with the wiring. When the lifting plate 23 and the cover plate move down to expose the top end of the wiring, the pressing plate 44 contacts the plane above the trapezoidal abutting block 45, so that the electromagnetic spring 412, the conductive sheet 48 and the power supply device form a circuit, the electromagnetic spring 412 is turned on, and the ends of the two V-shaped rods 410 close to the wiring are driven to approach each other until the clamping arc block 411 tightly adheres to the wiring, clamping and squeezing the upper end of the wiring. At the same time, due to the resistance of the trapezoidal abutting block 45 to the pressing plate 44 and the telescopic performance of the telescopic rod 43, the pressing plate 44 is limited above the trapezoidal abutting block 45 during the assembling process, keeping the upper end of the wiring always on the same horizontal line during the assembling process and avoiding bending of the wiring during the assembling process;

[0057] Since the lifting rod 414 and the fixed cylinder 415 in the telescopic rod 43 can have relative displacement during the assembling process, the connecting rod 54 can drive the annular piston plate 53 to perform reciprocating vertical displacement in the annular air extraction box 52, continuously pump the outside air into the annular filter box 51 through the air inlet pipe 57, filter the dust and impurities in the air through the filter screen arranged inside the annular filter box 51, and convey the filtered air into the annular air extraction box 52 through the air delivery pipe 55, and discharge it to the periphery of the assembling position through the exhaust port to purify the air around the assembling position;

[0058] When relative displacement occurs between the lifting rod 414 and the fixed cylinder 415 in the telescopic rod 43, the lifting rod 414 can rotate under the action of the external thread and the internal thread on the inner wall of the fixed cylinder 415, and then drive the toothed ring 61 to rotate through the third gear 64, the fourth gear 65, the transmission rod 62 and the second gear 63, so that the rotating ring 56 drives the air inlet pipe 57 to perform circular motion, enabling the air in all directions around the assembling position to be pumped into the annular filter box 51 for filtering.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
