Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a fully automatic winding machine. Background Technology

[0002] Nickel-metal hydride (NiMH) batteries are high-performance rechargeable batteries. The positive electrode active material of a NiMH battery is Ni(OH)₂ (called the NiO electrode), and the negative electrode active material is a metal hydride, also known as a hydrogen storage alloy (the electrode is called the hydrogen storage electrode). Therefore, compared to lithium-ion batteries, the positive and negative electrode sheets of NiMH batteries are thicker. The placement and winding of the separator also differ from lithium-ion batteries. In NiMH batteries, both the separator and the positive and negative electrode sheets are cut to a fixed length before being stacked. Therefore, the separator length is twice that of the positive and negative electrode sheets. After being cut to a fixed length, the separator is placed on a support fixture, the negative electrode sheet is placed on the separator, and then the separator is flipped over to cover the negative electrode sheet. The positive electrode sheet is then placed on the separator in the position of the negative electrode sheet, and finally, the winding is completed. During the separator flipping process, current technologies mostly use manual labor or robotic arms, which suffers from low flipping efficiency and easy damage to the separator.

[0003] On the other hand, in the existing technology, the negative electrode sheet, separator, and positive electrode sheet are stacked and wound into a core in sequence, and after the steel shell is loaded, the core is put into the steel shell. The existing technology uses multiple devices to realize the separator cutting process, the negative electrode sheet-separator-positive electrode sheet stacking process, the winding process, and the shell insertion process. It is necessary to transport and transfer between various devices. There is no fully automated production equipment that integrates the above multiple processes in the existing equipment, resulting in low production efficiency and hindering the improvement of production capacity.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0029] Example

[0030] To address the aforementioned technical problems, this embodiment provides a fully automatic film winding machine, such as... Figure 1 As shown, the device includes a rotatable conveyor turntable 90, on which several ring-shaped support fixtures 91 are arranged. Along the conveying path of the conveyor turntable 90, a diaphragm feeding mechanism 10, a first electrode feeding mechanism 20, a diaphragm flipping mechanism 30, a second electrode feeding mechanism 40, a winding mechanism 50, and a housing insertion mechanism 60 are sequentially arranged. The diaphragm feeding mechanism 10 cuts the diaphragm to a fixed length and feeds it onto the support fixtures 91. The first electrode feeding mechanism 20 places the first electrode onto the diaphragm of the support fixture 91. The diaphragm flipping mechanism 30 flips the diaphragm and covers the first electrode. The second electrode feeding mechanism 40 places the second electrode on the diaphragm and above the first electrode. The winding mechanism 50 winds the first electrode, diaphragm, and second electrode into a core. The housing insertion mechanism 60 inserts the core into a steel housing. Furthermore, the process of cutting the diaphragm, stacking the negative electrode sheet, diaphragm, and positive electrode sheet, winding the diaphragm sheet, and inserting the diaphragm sheet into the casing is fully automated, improving production efficiency and capacity. At the same time, the diaphragm flipping mechanism 30 enables the diaphragm to be flipped on the support fixture 91, improving the quality of diaphragm flipping while ensuring the efficiency of diaphragm flipping.

[0031] Specifically, current battery cell manufacturing processes require two different separators. Before loading the two separators, one separator needs to be cut onto the other, the two separators are then welded together, and finally the positive electrode, separator, and negative electrode are stacked and wound sequentially. Therefore, as... Figure 2-3As shown, the diaphragm feeding mechanism 10 includes a diaphragm for transport and a cutting assembly 150 disposed on the diaphragm transport path. A shearing assembly 130 is used to cut the diaphragm, and a transfer assembly 170 is disposed behind the cutting assembly 150. The diaphragm includes a first diaphragm 110 and a second diaphragm 120. Specifically, a welding assembly 140 and a cutting assembly 150 are disposed on the transport path of the first diaphragm 110 and the second diaphragm 120. A shearing assembly 130 is disposed on the transport path of the second diaphragm 120. The shearing assembly 130 is used to cut the second diaphragm 120 and place it on the first diaphragm 110. The welding assembly 140 is used to weld the first diaphragm 110 and the second diaphragm 120. The transfer assembly 170 is disposed behind the cutting assembly 150. Then, the second diaphragm 120 is cut by the shearing component 130 and placed on the first diaphragm 110. The welding component 140 welds the first diaphragm 110 and the second diaphragm 120. The welding component 150 then cuts the welded first diaphragm 110 and the second diaphragm 120 to a fixed length. Finally, the transfer component 170 places the welded first diaphragm 110 and the second diaphragm 120 on the support fixture 91. This realizes the automatic production of the cutting-welding-fixed-length cutting process of the first diaphragm 110 and the second diaphragm 120, achieving automated production and greatly improving production efficiency.

[0032] It also includes a first tray 111 for feeding the first diaphragm 110 and a second tray 121 for feeding the second diaphragm 120. The first diaphragm 110 is conveyed downward to the welding assembly 140 via a guide assembly 112, which is equipped with a conveying roller and has the function of conveying the first diaphragm 110. The second diaphragm 120 is cut by a shearing assembly 130 and then conveyed to the welding assembly 140, causing the first diaphragm 110 and the second diaphragm 120 to be misaligned. The shearing assembly 130 then cuts the second diaphragm 120 and conveys it to the welding assembly 140. The welding assembly 140 then welds the cut second diaphragm 120 onto the first diaphragm 110, realizing automatic cutting and welding and improving production efficiency.

[0033] Furthermore, in order to achieve the cutting of the second diaphragm 120, such as... Figure 2As shown, the shearing assembly 130 includes a positioning assembly 133 for pressing the second diaphragm 120 and a first cutter 131 disposed between the positioning assembly 133 and the welding assembly 140. The positioning assembly 133 is provided with a first driver 132 for driving the cutter 131. For example, the first driver 132 may be a cylinder. After the second diaphragm 120 passes through the positioning assembly 33, it passes under the cutter 31 and moves to the welding assembly 140, and is stacked on top of the first diaphragm 110. At this time, the first driver 132 drives the cutter 131 to rise and cut, thereby cutting the second diaphragm 120. Then, the welding assembly 140 welds the cut second diaphragm 120 onto the first diaphragm 110.

[0034] Furthermore, the positioning component 133 includes a fixed base 1331, a pressure roller 1332 rotatably mounted on the fixed base 1331, and a second driver 1333 with its drive end connected to the pressure roller 1332. For example, the second driver 1333 can be a motor, which drives the pressure roller 1332 to rotate, thereby conveying the second diaphragm 120 forward. When the cutter 131 cuts the second diaphragm 120, the pressure roller 1332 stops rotating. At this time, the pressure roller 1332 presses against the second diaphragm 120, thus positioning the second diaphragm 120 and facilitating the cutter 131 to cut the second diaphragm 120.

[0035] To weld the second diaphragm 120 and the first diaphragm 110, the welding assembly 140 includes a welding block 141 and a third actuator 142 that drives the welding block 141 to move up and down. The third actuator 142 can be a cylinder, which drives the welding block 141 to abut against the second diaphragm 120 and the first diaphragm 110, thereby welding the second diaphragm 120 onto the first diaphragm 110.

[0036] Furthermore, the welded second diaphragm 120 and first diaphragm 110 continue to be conveyed forward. A tension adjustment assembly 160 is also provided between the welding assembly 140 and the cutting assembly 150. The tension adjustment assembly 160 adjusts the tension of the welded second diaphragm 120 and first diaphragm 110. Specifically, the tension adjustment assembly 160 includes a tension roller 161 and an adjusting member 162 for adjusting the lifting position of the tension roller 161. The welded second diaphragm 120 and first diaphragm 110 pass over the tension roller 161 and are conveyed forward. The adjusting member 162 can be a screw, and it is threaded to one end of the tension roller 161. By rotating the adjusting member 162, the movement of the lifting tension roller 161 is adjusted, thereby adjusting the tension.

[0037] After welding, the second diaphragm 120 and the first diaphragm 110 are conveyed to the cutting assembly 150 after passing through the tension adjustment assembly 160. Alternatively, a positioning assembly 133 can be provided between the cutting assembly 150 and the tension adjustment assembly 160. The diaphragm then passes through the positioning assembly 133 before entering the cutting assembly 150 for cutting. The positioning assembly 133 serves to convey and fix the second diaphragm 120 and the first diaphragm 110. Figure 3 As shown, the cutting assembly 150 includes a second cutter 151 and a fourth driver 152 connected to the second cutter 151. For example, the fourth driver 152 may be a cylinder, which drives the second cutter 151 to cut the welded second diaphragm 120 and the first diaphragm 110 to a fixed length, thereby obtaining a diaphragm of the required length.

[0038] Furthermore, a transfer assembly 170 is also included, located behind the cutting assembly 150. The transfer assembly 170 transfers the cut second diaphragm 120 and first diaphragm 110 to the next workstation. Specifically, the transfer assembly 170 includes an adsorption element 172, a fifth actuator 171, and a sixth actuator 173. Both the fifth actuator 171 and the sixth actuator 173 are cylinders. The sixth actuator 173 is positioned horizontally, and the fifth actuator 171 is positioned vertically. The fifth actuator 171 is located at the drive end of the sixth actuator 173, and the adsorption element 172 is located at the drive end of the fifth actuator 171. The fifth actuator 171 drives the adsorption element 172 to move towards the second diaphragm 120 and the first diaphragm 110, using vacuum to adsorb the second diaphragm 120 and the first diaphragm 110. The sixth actuator 173 then drives the second diaphragm 120 and the first diaphragm 110 to move to the support fixture 91.

[0039] Furthermore, in the following text, the welded second diaphragm 120 and the first diaphragm 110 are collectively referred to as diaphragms. After the diaphragms are placed on the support fixture 91, in order to load the first electrode sheet onto the diaphragms of the support fixture 91, as follows... Figure 5 As shown, the first electrode feeding mechanism 20 includes a transmission line 21, a suction plate 22 disposed above the transmission line 21, and a first driving assembly 23 for driving the suction plate 22 to move. The transmission line 21 is used to transport the first electrode. The first driving assembly 23 can be a two-axis motion mechanism composed of cylinders. After the first driving assembly 23 drives the suction plate 22 to pick up the first electrode, it is transferred to the diaphragm of the supporting fixture 91. After the diaphragm is flipped by the aforementioned diaphragm flipping mechanism 30, the second electrode is fed by the second electrode feeding mechanism 40. The second electrode feeding mechanism 40 has the same structure as the first electrode feeding mechanism 20.

[0040] Furthermore, after the first electrode is fed onto the diaphragm of the supporting fixture 91, in order to flip the diaphragm over to cover the first electrode, as follows: Figure 6-8 As shown, the support fixture 91 includes an electrode support plate 920 and a diaphragm flipping plate 910 distributed along the length of the first electrode. A diaphragm flipping assembly 950, movable toward the electrode support plate, is disposed on the diaphragm flipping plate 910. The lower side of the diaphragm flipping assembly 950 near the electrode support plate 920 is chamfered or rounded. The diaphragm flipping mechanism 30 includes a flipping drive assembly that drives the diaphragm flipping assembly 950 to move toward the electrode support plate. The electrode support area 920 is used to place the first electrode 940, and the diaphragm flipping area 910 is used to place the diaphragm 930. Since the technical solution provided in this embodiment is applied to the winding process of nickel-metal hydride batteries, the separator 930 is not only placed on the separator flipping area 910, but also extends to the electrode support area 920. That is, the length of the separator 930 is not less than twice that of the first electrode 940. When the separator 930 is placed, the separator 930 covers both the electrode support area 920 and the separator flipping area 910.

[0041] First, place the diaphragm 930, then place the first electrode 940 on the electrode support area 920. At this time, the first electrode 940 presses part of the diaphragm 930 underneath. Next, the diaphragm 30 on the diaphragm flipping area 910 needs to be flipped over to cover the first electrode 940, so that the first electrode 940 and the diaphragm 930 are sandwiched together. Then, the second electrode is placed on top of the diaphragm 930. That is, the stacking method is diaphragm 30-first electrode 940-diaphragm 930-second electrode.

[0042] A diaphragm flipping assembly 950 is disposed on the upper end face of the diaphragm flipping plate 910; the diaphragm flipping assembly 950 includes a flipping pressing block 951, and a flipping driving assembly drives the flipping pressing block 951 to move toward the electrode support plate 920; one end of the flipping pressing block 951 near the electrode support plate 920 is a flipping pressing part 9511; the upper side of the flipping pressing part 9511 is a straight line perpendicular to the length direction of the first electrode, and the lower side is chamfered or rounded. When the lower side contacts the first electrode 940 below the diaphragm 930, it will push the diaphragm 930 to flip upward. The diaphragm flipping assembly 950 continues to move, and the diaphragm 930 will then complete the flipping action under the action of chamfering or rounding. After flipping, it will cover the first electrode 940. After the flipping is completed, the diaphragm flipping assembly 950 will reset. During the reset process, the diaphragm flipping assembly will roll over the already flipped diaphragm 930 again, so that the diaphragm 930 and the first electrode 940 are further adhered, preventing the diaphragm 930 from flipping up and affecting the winding process.

[0043] When the diaphragm 930 is flipped, the upper side of the flipping pressing part 9511 abuts against the bottom of the diaphragm 930 and drives the diaphragm 930 in the flipping area 910 to move towards the electrode support area 920. When the upper side moves to the edge of the first electrode 940, since the height of the upper side is not less than the sum of the thicknesses of the first electrode 940 and the diaphragm 930, the lower side of the flipping pressing part 9511, which is chamfered or rounded, contacts the first electrode 940 below the diaphragm 930, thereby pushing the diaphragm 930 to flip upward. The diaphragm flipping assembly 950 continues to move, and the diaphragm 930 completes the flipping action under the action of the chamfer or rounded corner, and after flipping, it covers the first electrode 940.

[0044] To enable the movement of the diaphragm flipping assembly 950, this embodiment further includes a driving member 952. The driving member 952 includes a sliding block 9521 that can slide along the length of the first electrode 940 on the diaphragm flipping area 910. The side of the flipping pressing block 951 away from the flipping pressing portion 9511 is pivotally connected to the sliding block 9521 by a torsion spring, allowing the flipping pressing block 951 to flip upwards with a downward pressing tendency. The sliding block 9521 is disposed in the diaphragm flipping area 910 by an elastic member. A lever 9522 is fixedly formed on the sliding block 9521. The lever 9522 is driven by a flipping drive assembly (not shown in the figure), which can be a cylinder.

[0045] The first electrode, diaphragm, and second electrode are stacked and wound together by the winding mechanism 50. A winding needle 911 is movably mounted on the supporting fixture 91. Figure 9 As shown, the winding mechanism 50 includes a winding head 51, a rotating assembly 52 for driving the winding head 51 to rotate, and a displacement driving assembly 53 for driving the winding head 51 to move toward the winding needle 911. For example, the displacement driving assembly 53 can be a cylinder, and the rotating assembly 52 can be a motor. The displacement driving assembly 53 drives the winding head 51 connected to the winding needle 911, and the rotating assembly 52 drives the winding head 51 to rotate, thereby driving the winding needle 911 to rotate to achieve the winding process. Since the winding mechanism 50 is prior art, it will not be described in detail here.

[0046] After the core is produced, it needs to be installed into a steel shell. For this purpose, such as... Figure 10As shown, the shell-loading mechanism 60 includes a pushing component 620 disposed on one side of the supporting fixture 91, and a first feeding component 630 disposed on one side of the pushing component 620. The first feeding component 630 is used to transport the steel shell to the pushing component 620. The pushing component 620 and the winding needle 911 respectively drive the steel shell and the winding core to move towards each other. The open end of the steel shell faces the winding core. The first feeding component 630 automatically feeds the steel shell, improving the feeding efficiency. The pushing component 620 drives the steel shell to move towards the winding core, and the winding needle 911 drives the winding core to move towards the steel shell. By moving the steel shell and the winding core towards each other, the winding core is loaded into the steel shell, thereby achieving efficient core loading and assembly, improving assembly and production efficiency.

[0047] It also includes a positioning block 640 disposed between the pushing component 620 and the supporting fixture 610, the positioning block 640 having a through hole for the steel shell to pass through. The pushing component 620 pushes the steel shell into the through hole of the positioning block 640 for positioning, and then the winding needle 911 drives the winding core to move toward the steel shell, thereby allowing the winding core to be installed into the steel shell.

[0048] A seventh actuator 912 connected to the winding needle 911 is provided on the support fixture 610. The seventh actuator 912 drives the winding needle 911 to move toward the positioning block 640. The seventh actuator 912 is a cylinder, which in turn drives the winding needle 911 to move toward the positioning block 40, so that the core on the winding needle 911 is loaded into the steel shell. Then, the seventh actuator 912 drives the winding needle 911 to reset, so that the assembled core and steel shell are reset back onto the support fixture 610. Then, the support fixture 610 is transferred to the unloading station by a turntable.

[0049] Furthermore, the pushing assembly 620 includes a support plate 621 for placing the steel shell, an eighth driver 623 disposed on the support plate 621, and a push rod 622 connected to the driving end of the eighth driver 623. The support plate 621 has a positioning groove 6211 for placing the steel shell. The first feeding assembly 630 feeds the steel shell onto the positioning groove 6211 of the support plate 621. The steel shell lies horizontally on the support plate 621 with its open end facing the core. The eighth driver 623 drives the push rod 622 to move towards the positioning block 640, thereby pushing the steel shell into the positioning block 640, ensuring that the winding needle 911 pushes the core towards the steel shell for assembly.

[0050] To achieve automatic feeding of steel shells, the first feeding assembly 630 includes a storage chute 632, a feeding block 633 disposed at the inlet of the storage chute 632, and a ninth driver 631 that drives the feeding block 633 to rotate. The outlet of the storage chute 632 is connected to the support plate 621. For example, the ninth driver 631 can be a motor, and the feeding block 633 has a feeding groove 6331 for accommodating the steel shell. In the initial state, the feeding groove 6331 is in a vertical state. The steel shell is fed into the feeding groove 6331, and then the ninth driver 631 drives the feeding block 633 to rotate, so that the feeding groove 6331 of the feeding block 633 is in a horizontal state, thereby changing the vertical steel shell to a horizontal state and sliding down from the storage chute 632 onto the support plate 621 of the pushing assembly 620, thereby achieving automatic feeding of the steel shell.

[0051] Furthermore, in the above scheme, a detector 634 is also provided on the storage chute 632. The detector 634 can be an in-situ sensor. The detector 634 detects the in-situ condition of the steel shell on the storage chute 632. Then, the feeding equipment feeds the steel shell to the storage chute 632 through the unloading block 633, preventing the steel shell on the storage chute 632 from running out and causing production chaos.

[0052] It also includes a steel shell feeding mechanism 70 located on one side of the shell loading mechanism 60, such as Figure 11 As shown, the steel shell feeding mechanism 70 includes a rotatably mounted transport component 710, a second feeding component 720, a gasket conveying component 740, and a sorting component 750 sequentially arranged on the transport path of the transport component 710. A stamping component 730 is arranged on the gasket conveying path facing the transport component 710. The stamping component 730 is used to stamp the gaskets on the gasket conveying component 740 into the steel shell. A first detection component 760 for detecting the opening direction of the steel shell is provided at the inlet of the second feeding component 720. The sorting component 750 is used to sort steel shells with different opening directions. The opening direction of the steel shell is detected by the first detection component 760, and then the steel shell is transported to the sorting component 750 via the transport turntable 710. The sorting component 750 then sorts the steel shells with different opening directions, and steel shells with the correct opening direction can be transported to the next process. The system enables automated feeding, inspection, gasket installation, and sorting of steel shells, saving manpower and resources, improving the accuracy of steel shell feeding, and greatly increasing production efficiency.

[0053] The outer circumferential surface of the transport component 710 has several grooves 711 for placing the steel shell, and an adsorption element is installed in the groove 711. The second feeding component 720 transports the steel shell to the groove 711 of the transport component 710, and the steel shell is fixed by the adsorption element in the groove 711. The adsorption element can be an electromagnet. A motor 712 is connected to the transport component 710, and the motor 712 drives the transport component 710 to rotate, thereby realizing the transport of the steel shell.

[0054] Furthermore, in the above scheme, the second feeding assembly 720 includes a feeding trough 723 extending from the discharge port to the transport assembly 710, a pusher 722 disposed at the inlet of the feeding trough 723, and a first driving member 721 connected to the pusher 722 at its driving end. The first driving member 721 can be a cylinder. For example, in actual production, a robotic arm can be used to transport the steel shell to the inlet of the feeding trough 723. The first detection assembly 760 is disposed at the inlet of the feeding trough 723, and one end face of the steel shell faces the first detection assembly 760. The detection assembly 760 can be a sensor, which detects whether the end face of the steel shell near the first detection assembly 760 is open. If it is open, it indicates that the steel shell is placed correctly. If not, the stamping assembly 730 does not perform shim assembly on the steel shell.

[0055] Furthermore, a first detector 724 is installed on the feeding trough 723 to detect the presence of steel shells. This ensures that there are sufficient steel shells in the feeding trough 723, preventing production chaos caused by a lack of steel shells.

[0056] Furthermore, the gasket conveying assembly 740 includes a conveyor roller 742 for conveying gaskets and a second drive member 741 for driving the conveyor roller 742 to rotate. Two conveyor rollers 742 are provided and arranged side-by-side, with the gasket passing between the two conveyor rollers 742. Exemplarily, the second drive member 741 is a motor, which drives the two conveyor rollers 742 to rotate in opposite directions, thereby conveying the gasket from bottom to top. When the steel shell is transferred to the position corresponding to the gasket, it is then pressed towards the gasket by the stamping assembly 730, thereby inserting the gasket into the steel shell.

[0057] Specifically, in the above solution, the stamping assembly 730 includes a fixing block 733 disposed on the gasket conveying path and through which the gasket passes, a stamping rod 732 passing through the fixing block 733 and facing the transport assembly 710, and a third driving member 731 with its driving end connected to the stamping rod 732. For example, the third driving member 731 can be a cylinder. The fixing block 733 has a through hole through which the stamping rod 732 passes. The third driving member 731 drives the stamping rod 732 through the through hole of the fixing block 733 and stamps it against the gasket, thus forming the gasket and pressing it into the steel shell. This process is skipped for steel shells with incorrect opening orientations.

[0058] Furthermore, the sorting component 750 includes a first unloading trough 751 and a second unloading trough 752 sequentially arranged on the conveying path of the transport component 710. A fourth driving member 753 and a fifth driving member are respectively arranged on the transport component 710 at positions corresponding to the first unloading trough 751 and the second unloading trough 752. For example, both the fourth driving member 753 and the fifth driving member can be cylinders. Both the driving ends of the fourth driving member 753 and the fifth driving member are provided with push rods. When the transport component 710 conveys the steel shell to the first unloading trough 751, if the opening direction of the steel shell is incorrect, the fourth driving member 753 pushes the steel shell into the first unloading trough 751 for storage; if the opening direction of the steel shell is correct, the transport component 710 continues to convey the steel shell to the second unloading trough 752, and the fifth driving member pushes the steel shell into the second unloading trough 752, and then it enters the first feeding component 630 through the second unloading trough 752.

[0059] A second detector 755 is provided on both the first feeding trough 751 and the second feeding trough 752 to detect the presence of the steel shell in the first feeding trough 751 and the second feeding trough 752. In some other embodiments, it can also be used to detect the opening direction of the steel shell.

[0060] It also includes a feeding mechanism 80. After the battery is assembled, the conveyor turntable 90 transfers the battery to the feeding mechanism 80, and then pushes the battery into the feeding mechanism 80. For example... Figure 12 As shown, the unloading mechanism 80 includes an unloading trough 81 and a conveyor line 82 connected to the unloading trough 81. In the above scheme, the core on the winding needle 911 is loaded into the steel shell, and then the seventh driver 912 drives the winding needle 911 to reset, so that the assembled core and steel shell are reset onto the carrying fixture 610. Then, the carrying fixture 610 is transferred to the unloading trough 81 by the conveyor turntable 90. For example, the core and steel shell on the winding needle 911 can be pushed to the unloading trough 81 for unloading. Alternatively, in some embodiments, the winding needle 911 can be an air shaft, which facilitates the core and steel shell to detach from the winding needle 911. A second detection component 84 is provided on the conveyor line 82. The second detection component 84 is used to detect the assembly quality of the core and steel shell. The conveyor line 82 is provided with a material distribution component 83. The material sorting component 83 consists of two conveyor lines, each with a corresponding pusher cylinder. Based on the detection results of the second detection component 84, the pusher cylinders push qualified and unqualified batteries into different conveyor lines.

[0061] In summary, this application's solution, by sequentially arranging a diaphragm feeding mechanism, a first electrode feeding mechanism, a diaphragm flipping mechanism, a second electrode feeding mechanism, a winding mechanism, and a shell-inserting mechanism along the conveying path of the conveyor turntable, achieves fully automated production of the diaphragm cutting process, the negative electrode-diaphragm-positive electrode stacking process, the winding process, and the shell-inserting process, thereby improving production efficiency and capacity. Simultaneously, the diaphragm flipping mechanism flips the diaphragm on the carrier fixture, ensuring efficient and high-quality diaphragm flipping while maintaining the flipping efficiency.

[0062] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
