Description

Technical Field

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

[0002] Sodium-ion battery is an emerging battery technology, similar to lithium-ion battery, but it uses sodium ions as the main charge carrier, and its working principle is based on the embedding and de-embedding of sodium ions between the positive and negative electrodes. During charging, sodium ions are released from the positive electrode material, migrate to the negative electrode through the electrolyte, and embed on the negative electrode; during discharging, sodium ions are de-embedded from the negative electrode and migrate back to the positive electrode.

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

[0004] However, the existing assembly machines usually have the following technical problems when assembling sodium ion batteries:

[0005] Before assembling the battery pack and the cover sheet, it is usually necessary to process the wiring to avoid entanglement or deformation of the wiring, which may cause fatigue of the internal material of the wiring and increase the risk of breakage. In the prior art, the wiring processing process is usually to first crimp the wiring, and then drive the wire puller to slide on the wiring for wire pulling. In this method, the crimping and wire pulling processes 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 reducing the assembly efficiency.

[0006] During the assembly process of the cover, the contact between the cover and the wiring and the gravity of the wiring itself can easily cause the wiring to bend, which in turn causes the metal part of the wiring to contact other parts of the battery, increasing the risk of short circuit, which not only reduces the performance and service life of the battery, but may also cause safety accidents such as fire or explosion.

[0020] Compared with the existing technology, the advantages of this sodium ion battery processing and manufacturing assembly machine are:

[0021] 1. The present invention sets a clamping and smoothing mechanism. Before the cover sheet is assembled on the battery pack and the protective shell, the screw is driven to rotate by the first motor, thereby driving the lifting plate to move from bottom to top in the vertical direction. In this process, the rack is first driven to move horizontally on the smoothing plate, so that the two clamping arc blocks are rotated to fit the wiring of the sodium ion battery. Then, the clamping arc blocks are kept clamped on the butt wires and the smoothing plate is pulled to move upward in the vertical direction, so that the wiring of the battery pack is smoothed from bottom to top, so that the wire pressing and wire pulling work can be carried out continuously, the work continuity is improved, the assembly efficiency of the battery pack is improved, and the driving source and the energy consumed in processing are saved at the same time.

[0022] 2. The present invention provides an anti-bending mechanism. After the wire pulling is completed, the first motor drives the screw to rotate in the opposite direction to move the lifting plate from top to bottom. At the same time, the assembly mechanism drives the cover plate to align with the wiring and move downward. When the lifting plate and the cover plate move down to the top of the wiring and are exposed, the pressing plate contacts the plane above the trapezoidal abutment block, so that the pressing plate and the conductive plates on the trapezoidal abutment block contact each other, and the elastic force of the electromagnetic spring drives the two V-shaped rods close to one end of the wiring to approach each other until the arc block is pinched to fit the wiring, and the upper end of the butt wire is pinched, and at the same time, the pressing plate is limited above the trapezoidal abutment block during the assembly process, so that the upper end of the wiring is always on the same horizontal line during the assembly process, and the wiring is prevented from bending during the assembly process, causing the metal part of the wiring to contact other components of the battery, thereby improving the performance and service life of the battery and avoiding the occurrence of safety accidents.

[0023] 3. The present invention provides an air purification mechanism, and continuous assembly work causes the annular piston plate to perform reciprocating vertical displacement in the vacuum box, thereby continuously pumping outside air into the annular filter box through the air inlet pipe, filtering dust and impurities in the air through the filter screen provided inside the annular filter box, and conveying the filtered air to the annular vacuum box through the air pipe, and discharged to the surrounding side of the assembly position through the exhaust port, purifying the air on the surrounding side of the assembly to prevent impurities such as dust and oil from falling between the battery pack and the cover plate, causing impurities such as dust and oil to enter the battery and affect its performance.

[0024] 4. The present invention sets a rotating mechanism. When relative displacement occurs between the lifting rod and the fixed cylinder in the telescopic rod, the lifting rod can rotate, so that the rotating ring can drive the air intake pipe to move in a circle, and the pumping position of the outside air is adjusted, so that the air in all directions around the assembly position can be pumped into the annular filter box for filtration, thereby improving the purification effect of the outside air and further avoiding the influence of dust and impurities on the battery performance.

DETAILED DESCRIPTION

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

[0035] Example: Refer to Figures 1 to 8 , an assembly machine for processing and manufacturing sodium ion batteries, comprising a machine body 1;

[0036] Two groups of symmetrically arranged clamping and smoothing mechanisms 2 are used to clamp the battery wiring and drive the clamping position upward to smooth the battery wiring. Each group of clamping and smoothing mechanisms 2 includes a fixed plate 21 arranged above the body 1, and the fixed plate 21 is fixedly connected to the upper end of the body 1 through a first support rod. The upper end of the fixed plate 21 is rotatably connected to a screw rod 22, and a lifting plate 23 that moves in the vertical direction is threadedly connected to the screw rod 22. A U-shaped plate 24 is fixedly connected to the side wall of the fixed plate 21, and 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 smoothing plates 27 are slidably connected to the side wall of the fixed plate 21 in the vertical direction, and each smoothing plate 27 is slidably connected to a rack 28 in the horizontal direction. A second hinge seat 29 is provided at the upper end of each rack 28, and a connecting rod 210 is provided between the two first hinge seats 26 and the two second hinge seats 29. A rotating rod 211 is rotatably connected to each smoothing plate 27, and a first gear 212 meshing with the rack 28 at the corresponding position is fixedly connected to each rotating rod 211. An extension rod 213 is fixedly connected to each rotating rod 211, and 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 limit rods 215 are fixedly connected to the fixed plate 21, and the two limit rods 215 are slidably connected to the lifting plate 23. The lifting plate 23 can be limited by the limit rods 215, so that the lifting plate 23 can only be vertically displaced in the vertical direction when the screw rod 22 rotates.

[0038] Specifically, the smoothing plate 27 and the fixed plate 21 are provided with a first sliding groove arranged in the horizontal direction and a second sliding groove arranged in the vertical direction, which are respectively used to limit the sliding of the rack 28 and the smoothing plate 27, ensuring that the rack 28 is first horizontally displaced relative to the smoothing plate 27, and the smoothing plate 27 is then vertically displaced relative to the fixed plate 21.

[0039] In view of the problem that the prior art requires that the wiring be crimped first, and then the wire puller is driven to slide on the wiring for wire pulling after the crimping is completed, in this method, the crimping and wire pulling processes need to be driven by two different drive sources, resulting in the inability to continuously process the wiring, reducing the continuity of the assembly process and lowering the assembly efficiency, the present invention sets a clamping and smoothing mechanism 2, and before the cover is assembled on the battery pack and the protective shell, the screw 22 is driven to rotate by the first motor 25, thereby driving the lifting plate 23 to move from bottom to top in the vertical direction. In this process, the first articulated seat 26, the second articulated seat 29 and the connecting rod 210 act , the rack 28 is first driven to move horizontally on the smoothing plate 27, thereby driving 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 continued upward movement of the lifting plate 23 will keep the rack 28 at the farthest end and pull the smoothing plate 27 to move upward in the vertical direction, so that the wiring of the battery pack is smoothed from bottom to top, so as to realize the continuous pressing and pulling of the wires, improve the continuity of the work, and improve the assembly efficiency of the battery pack, while saving the driving source and the energy consumed in the processing.

[0040] The assembly mechanism 3 is used to assemble the cover sheet on the battery pack and the upper end of the protective shell. The assembly mechanism 3 includes a cover frame 31 fixedly connected to the upper part of the body 1 and a pick-and-place assembly arranged above the cover frame 31.

[0041] Specifically, the pick-and-place assembly includes a guide rail 32 arranged above the lid 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 to the inside of the guide rail 32 in the horizontal direction, and a second motor 34 for driving the slider 33 is fixedly connected to the outer wall of one side of the guide rail 32. More specifically, a screw rod is fixedly connected to the inside of the guide rail 32, the slider 33 is threadedly connected to the screw rod, and the output end of the second motor 34 is fixedly connected to the screw rod, the bottom end of the slider 33 is fixedly connected to a support plate 35, the lower end of the support plate 35 is fixedly connected to two electric push rods 36, and the output ends of the two electric push rods 36 are fixedly connected to suction cups 37, and each suction cup 37 is provided with a micro vacuum pump and an exhaust nozzle with an opening and closing valve installed inside above each suction cup 37.

[0042] During actual assembly, keep the slider 33 and the support plate 35 just above the cover frame 31, and drive the suction cup 37 downward by the electric push rod 36 so that the suction cup 37 is squeezed against the upper wall of the cover sheet, and then use a micro vacuum pump to extract the air between the suction cup 37 and the upper wall of the cover sheet, 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, the second motor 34 drives the screw rod to rotate, driving the slider 33 and the support plate 35 to move to just above the battery pack and the protective shell. After the electric push rod 36 moves the suction cup 37 downward to the specified position, the opening and closing valve in the exhaust nozzle is opened, so that the cover sheet is no longer fixed to the suction cup 37, thereby realizing the assembly of the cover sheet, the battery pack and the protective shell.

[0043] An anti-bending mechanism 4 is provided between the fixed plate 21 and the two smoothing plates 27, which is used to prevent the wiring from bending during the assembly of the cover plate. The anti-bending mechanism 4 includes a guide plate 41 fixedly connected to the fixed plate 21, a connecting plate 42 fixedly connected between the two smoothing plates 27, a telescopic rod 43 fixedly connected to the upper end of the connecting plate 42, a pressing plate 44 provided on the telescopic rod 43, the pressing plate 44 is slidably connected to the side wall of the guide 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 guide plate 41 near the upper end, and the trapezoidal abutting block 45 extending to the other side of the guide plate 41 is fixedly connected with a reset Plate 46, two first reset springs 47 are provided between the reset plate 46 and the side wall of the guide plate 41, conductive sheets 48 are provided at the same position of the lower wall of the pressing plate 44 and the upper wall of the trapezoidal abutment block 45, the upper end of the pressing plate 44 is fixedly connected to a fixed shaft 49, and two V-shaped rods 410 are rotatably connected to the fixed shaft 49, each V-shaped rod 410 is provided with a pinching arc block 411, 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 body 1 through two conductive sheets 48, and a tension spring 413 is elastically connected to the side of the two V-shaped rods 410 away 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 to the pressing plate 44. The setting of the lifting rod 414 and the fixed cylinder 415 enables relative displacement between the clamping arc block 411 on the upper side and the clamping arc block 214 on the lower side, so that when the clamping arc block 214 and the cover plate move downward synchronously, the clamping arc block 411 always clamps the upper end of the sodium-ion battery connection.

[0045] In view of the problem that in the prior art, the wiring is prone to bending due to the contact between the cover sheet and the wiring and the gravity of the wiring itself during the assembly process of the cover sheet, the present invention provides an anti-bending mechanism 4. After the wire pulling is completed, the first motor 25 drives the screw rod 22 to rotate in the opposite direction, so that the lifting plate 23 moves from top to bottom. At the same time, the electric push rod 36 in the assembly mechanism 3 drives the cover sheet to move downward in alignment with the wiring. When the lifting plate 23 and the cover sheet move down to the top of the wiring and are exposed, the pressing plate 44 contacts the plane above the trapezoidal abutment block 45 (in the process of the lifting plate 23 moving from bottom to top, the pressing plate 44 abuts against the inclined surface on the side of the trapezoidal abutment block 45, which can push the trapezoidal abutment block 45 to slide, so that the pressing plate 44 will not interfere with the movement when it moves up. After the pressing plate 44 moves to the top of the trapezoidal abutment block 45, the trapezoidal abutment block 45 pops out under the action of the first return spring 47, ensuring that the pressing plate 44 can abut against the trapezoidal abutment block 45 when it moves down. The pressing plate 44 is limited by the plane above the trapezoidal abutment block 45, so that the pressing plate 44 and the conductive sheet 48 on the trapezoidal abutment block 45 contact each other, so that the electromagnetic spring 412, the conductive sheet 48 and the power supply device form a passage, and the electromagnetic spring 412 is opened. Since the elastic force of the electromagnetic spring 412 is much greater than the elastic force of the tension spring 413, the two V-shaped rods 410 can be driven to approach each other near one end of the wiring until the arc block 411 is pinched to fit the wiring, and the upper end of the wiring is clamped and pinched. At the same time, due to the resistance of the trapezoidal abutment block 45 to the pressing plate 44 and the retractable performance of the telescopic rod 43, the pressing plate 44 can be limited above the trapezoidal abutment block 45 during the assembly process, so that the upper end of the wiring is always on the same horizontal line during the assembly process, avoiding bending of the wiring during the assembly process, causing the metal part of the wiring to contact other parts of the battery, thereby improving the performance and service life of the battery and avoiding the occurrence of safety accidents.

[0046] An air purification mechanism 5 is provided at a position above the assembly mechanism 3 of the machine body 1. 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 the plurality of straightening plates 27 are fixedly connected to an annular air suction box 52. An annular piston plate 53 is sealingly and slidably connected inside the annular air suction box 52. A connecting rod 54 is fixedly connected to the bottom end of the lifting rod 414. The bottom end of the connecting rod 54 is rotatably connected to the upper end of the annular piston plate 53. An air supply pipe 55 is connected between the annular filter box 51 and the annular air suction box 52. A rotating ring 56 is penetrated through the upper wall of the annular air suction box 52. The rotating ring 56 is circumferentially slidably connected to the upper wall of the annular air suction box 52. An air inlet pipe 57 connecting the outside and the inside of the annular filter box 51 is penetrated through the rotating ring 56. An exhaust port is provided at the upper end of the annular air suction box 52. Both the air supply pipe 55 and the exhaust port are provided with a one-way valve.

[0047] Specifically, the one-way valve is set so that when the annular piston plate 53 performs reciprocating vertical displacement in the annular vacuum box 52, the purified air in the annular filter box 51 can only be pumped into the annular vacuum box 52 through the air supply pipe 55, and the air in the annular vacuum box 52 is discharged to the surrounding side of the assembly position, thereby avoiding backflow of air during the continuous transportation process 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 an external thread, and the inner wall of the fixing tube 415 is provided with an internal thread matching the external thread. The mutual cooperation between the external thread and the internal thread enables the lifting rod 414 to rotate itself when the lifting rod 414 is displaced relative to the fixing tube 415.

[0049] In order to prevent dust, oil and other impurities from entering the battery during the assembly process and affecting the battery performance, the present invention sets an air purification mechanism 5. During the assembly process, the contact between the trapezoidal abutment block 45 and the pressing plate 44 will cause the lifting rod 414 in the telescopic rod 43 to move relative to the fixed cylinder 415, and then drive the annular piston plate 53 to move upward in the annular air pumping box 52 through the connecting rod 54. After the assembly is completed, it is necessary to press the trapezoidal abutment block 45 to press the pressing plate 44 to reset under the action of gravity to ensure the assembly of the next sodium ion battery. At this time, the annular piston plate 53 moves downward in the annular air pumping box 52. Continuous assembly work causes the annular piston plate 53 to reciprocate vertically in the annular air pumping box 52, thereby continuously pumping outside air into the annular filter box 51 through the air inlet pipe 57, filtering dust and impurities in the air through the filter net arranged inside the annular filter box 51, and conveying the filtered air to the annular air pumping box 52 through the air supply pipe 55, and being discharged to the surrounding side of the assembly position through the exhaust port, so as to purify the air around the assembly side to prevent dust, oil and other impurities from falling between the battery pack and the cover plate.

[0050] A rotating mechanism 6 is provided on the peripheral side of the annular filter box 51, which is used to drive the air intake pipe 57 to perform circular motion to improve the purification effect of the surrounding air. The rotating mechanism 6 includes a gear ring 61 rotatably connected to the peripheral outer wall of the annular filter box 51, and the gear 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, and the top end of each transmission rod 62 is fixedly connected to a second gear 63 that meshes with the gear ring 61, and the bottom end of each transmission rod 62 is fixedly connected to a third gear 64, and the top end of each lifting rod 414 is fixedly connected to a fourth gear 65 that meshes 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 movable block 71 is fixedly connected to the outer wall of the rotating ring 56, and a second return spring 72 is provided between the fixed block 7 and the movable block 71. The elastic force of the second return spring 72 can rotate the rotating ring 56 and the air intake pipe 57 back to the initial position after each battery assembly process, thereby ensuring the purification effect of the surrounding air when the next battery is assembled.

[0052] In order to improve the comprehensiveness of air purification, the present invention sets a rotating mechanism 6. When relative displacement occurs between the lifting rod 414 and the fixed cylinder 415 in the telescopic rod 43, 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, and then drive the transmission rod 62 to rotate through the third gear 64 and the fourth gear 65, and further drive the gear ring 61 to rotate through the second gear 63, so that the rotating ring 56 can drive the air intake pipe 57 to perform a circular motion, and adjust the pumping position of the outside air, so that the air in all directions around the assembly position can be pumped into the annular filter box 51 for filtration, thereby improving the purification effect of the outside air and further avoiding the influence of dust and impurities on the battery performance.

[0053] The present invention can be explained by the following operation mode:

[0054] During the actual assembly, the slider 33 and the support plate 35 are kept just above the cover frame 31, and the electric push rod 36 is used to drive the suction cup 37 to move downward, so that the suction cup 37 is pressed against the upper wall of the cover sheet, and then the air between the suction cup 37 and the upper wall of the cover sheet is extracted by a micro air pump, so that the cover sheet can be adsorbed on the suction cup 37 under a negative pressure state. After the electric push rod 36 drives the suction cup 37 to move upward to lift the cover sheet, the second motor 34 is used to drive the screw rod to rotate, driving the slider 33 and the support plate 35 to move to just above the battery pack and the protective shell;

[0055] The screw rod 22 is driven to rotate by the first motor 25, driving the lifting plate 23 to move from bottom to top in the vertical direction. In this process, the first hinge seat 26, the second hinge seat 29 and the connecting rod 210 will first drive the rack 28 to move horizontally on the smoothing plate 27, thereby driving 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, and then the rack 28 moves to the farthest end, and the continued upward movement of the lifting plate 23 will keep the rack 28 at the farthest end and pull the smoothing plate 27 to move upward in the vertical direction, so that the wiring of the battery pack is smoothed from bottom to top;

[0056] The first motor 25 drives the screw rod 22 to rotate in the opposite direction, so that the lifting plate 23 moves 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 in alignment with the wiring. When the lifting plate 23 and the cover plate move down to the top of the wiring and are exposed, the pressing plate 44 contacts the plane above the trapezoidal abutment block 45, so that the electromagnetic spring 412, the conductive sheet 48 and the power supply device form a passage. The electromagnetic spring 412 is opened, driving the two V-shaped rods 410 close to one end of the wiring to approach each other until the arc block 411 is tightly pressed against the wiring to clamp and pinch the upper end of the wiring. At the same time, due to the resistance of the trapezoidal abutment 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 abutment block 45 during the assembly process, keeping the upper end of the wiring always at the same horizontal line during the assembly process to avoid bending of the wiring during the assembly process.

[0057] Since the lifting rod 414 and the fixing cylinder 415 in the telescopic rod 43 can be relatively displaced during the assembly process, the annular piston plate 53 can be driven by the connecting rod 54 to perform reciprocating vertical displacement in the annular air extraction box 52, and the outside air is continuously pumped into the annular filter box 51 through the air inlet pipe 57, and the dust and impurities in the air are filtered through the filter screen arranged inside the annular filter box 51, and the filtered air is transported to the annular air extraction box 52 through the air delivery pipe 55, and discharged to the surrounding side of the assembly position through the exhaust port, so as to purify the air around the assembly side;

[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 of the inner wall of the fixed cylinder 415, and then the gear ring 61 is driven 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 can drive the intake pipe 57 to perform a circular motion, so that the air in all directions around the assembly position can be pumped into the annular filter box 51 for filtration.

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