Description

Technical Field

[0001] This invention relates to the field of battery stacking technology, and in particular to a battery stacking machine for the production of energy storage batteries for new energy vehicles. Background Technology

[0002] With the rapid development of new energy vehicles and the energy storage industry, lithium-ion batteries, as core energy storage components, are directly related to product performance, cost, and market competitiveness due to their production efficiency and quality consistency. Currently, mainstream battery stacking machines mainly adopt "Z"-shaped stacking or winding stacking processes. In a typical "Z"-shaped stacking machine, the basic workflow is as follows: the separator is continuously unwound to form a specific gap; a robotic arm or picking device alternately picks up single electrode sheets from the positive and negative electrode sheet boxes and precisely places them in the preset position on the separator; then, through the reciprocating motion of the separator or the action of the folding mechanism, the separator wraps the electrode sheet, thereby completing the alternating stacking of positive electrode, separator, and negative electrode.

[0003] However, the existing technologies still have some problems: due to limitations in process principles, existing equipment must strictly follow a serial operation mode of "take one sheet, place one sheet, stack one sheet, press down," and the stacking speed is limited by the reciprocating motion of the robotic arm, the time required for visual alignment, and the action cycle of the diaphragm bending mechanism. Some technologies employ diaphragm pre-forming (such as pre-pressing creases), which aim to simplify the stacking process, but the crease spacing and shape are determined by molds of fixed dimensions. When the product model changes or the electrode size changes, the machine must be stopped and the entire set of matching molds replaced. Therefore, a battery stacking machine for the production of energy storage batteries for new energy vehicles is proposed to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing a battery stacking machine for the production of energy storage batteries for new energy vehicles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A battery stacking machine for producing energy storage batteries for new energy vehicles includes a base plate, a side frame fixed to one side of the base plate, a middle layer plate fixed to the top of both sides of the side frame, a side plate fixed to the top of both sides of the base plate, and a center plate rotatably connected between the two side plates. The top of the center plate is provided with several alternating first and second slide grooves. Bottom sliders are installed in both the first and second slide grooves. The bottom sliders are slidably connected to the center plate. End support rods are slidably connected in the bottom sliders. The bottom sliders in the first and second slide grooves are all at their opposite ends. A bearing rod is slidably connected on the side of the bottom slider away from the end support rod. The same pressure rod is fixed to the end of the bearing rod on the same side away from the bottom slider. The bottom of each end support rod is fixedly connected to a bottom connecting rod. The end of the bottom connecting rod on the same side away from the end support rod is slidably connected to the bottom mounting plate through a groove. A connecting rod is fixedly connected to one side of the bottom mounting plate. One end of the connecting rod is threadedly connected to a threaded rod through a fixing block. One end of the threaded rod is rotatably connected to a fixing plate. The fixing plate is fixedly connected to the bottom of the center plate. A second motor is set on the side of the threaded rod away from the fixing plate. The second motor is fixedly connected to the bottom of the center plate through a bracket. The output shaft of the second motor is fixedly connected to the threaded rod.

[0006] A first motor is fixedly connected to one side of the bottom mounting plate, and a winding wheel is fixedly connected to the output shaft of the first motor. A traction rope is fixedly connected to the outer wall of the winding wheel.

[0007] Several evenly distributed positioning rods are fixed to the bottom of the bottom mounting plate. A fixing ring is installed on the bottom connecting rod near the bottom of the bottom mounting plate. The traction rope passes through the fixing ring at the bottom of the bottom mounting plate in sequence, then wraps around the positioning rod below it, and then passes through the fixing ring at the bottom of the next bottom mounting plate, and so on, so that it can only move along a specific path.

[0008] The bottom connecting rod overlaps with the bottom mounting plate and has an opening on the side closest to the first motor. The bottom mounting plate has a hollow structure inside, and an internal rotating rod is provided between the two bottom connecting rods. The middle part of the internal rotating rod is rotatably connected to the bottom mounting plate.

[0009] The two ends of the internal rotating rod are provided with sequential retraction mechanisms arranged in a circumferential array, including inclined plate clamps and two internal springs. The two internal springs are located on both sides of the internal rotating rod, and the ends of the two internal springs are fixedly connected to the bottom mounting plate and the end of the inclined plate clamp, respectively. The top of the internal rotating rod is fixedly connected to the upper inclined plate clamp by a traction rope. The bottom of the internal rotating rod is provided with a push rod between it and the lower inclined plate clamp, and the push rod is fixedly connected to the inclined plate clamp.

[0010] A rotating wheel frame is installed on the side of the center plate near the side frame, and a support plate is installed on the side of the center plate away from the side frame. A mounting rod is fixedly connected to one side of the support plate, and a load-bearing slide plate is slidably connected to the surface of the support plate. An internal slide is slidably connected inside the mounting rod, and an elastic clamp is hinged to the end of the internal slide. A support spring is fixedly connected between the load-bearing slide plate and the mounting rod.

[0011] A transverse electric telescopic rod is fixed to the top of the side frame. An end connecting block is fixed to the free end of the transverse electric telescopic rod. A connecting slide is slidably connected to one side of the end connecting block. A longitudinal electric telescopic rod is fixed to the bottom of the connecting slide. The longitudinal electric telescopic rod is slidably connected to the base plate. A slide rail is fixed to the bottom of the connecting slide. Several sliding claws are slidably connected to the bottom of the slide rail.

[0012] A limiting groove is fixed to one side of the pressure rod, and a limiting rod is opened on one side of the side plate. The limiting rod surrounds the pivot connecting the center plate and the side plate, and the limiting groove passes through the limiting rod and is restricted by it.

[0013] Compared with existing technologies, the advantages of this invention are as follows: This invention uses an array of end supports to form the entire diaphragm into multiple precisely sized wavy pockets in a single operation, and utilizes a multi-link sliding gripper assembly to achieve simultaneous pickup and one-time insertion of multiple electrode sheets. This overcomes the limitations of the serial cycle time of traditional stacking machines, significantly improving the efficiency of the core stacking action.

[0014] The size (trough depth) of the diaphragm pocket is controlled solely by adjusting the opposing movement distance of the end support rods, directly driven by a high-precision threaded rod and servo system. When changing product specifications, no physical mold needs to be replaced; adjustments can be made instantly simply by changing parameters within the control system.

[0015] The sequential unlocking mechanism ensures that after the diaphragm is flipped and stacked, the end supports retract in a strictly top-to-bottom order. This effectively prevents the diaphragm from becoming disorderly loose and wrinkled due to the sudden loss of all support, thus ensuring the initial orderliness of the internal structure of the stack.

[0016] The electrode is slightly lifted away from the center plate by the support rod, so that the edge of the diaphragm hangs down naturally. From a mechanical structure perspective, this ensures that the diaphragm completely covers all edges of the electrode in three-dimensional space, avoiding the risk of short circuit due to exposure of the electrode edge caused by alignment error.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Reference Figure 1 - Figure 12 A battery stacking machine for producing energy storage batteries for new energy vehicles includes a base plate 1, a side frame 3 fixedly connected to one side of the base plate 1, a middle layer plate 2 fixedly connected to the top of both sides of the side frame 3, a side plate 4 fixedly connected to the top of both sides of the base plate 1, and a center plate 5 rotatably connected between the two side plates 4. A transverse electric telescopic rod 8 is fixedly connected to the top of the side frame 3. An end connecting block 7 is fixedly connected to the free end of the transverse electric telescopic rod 8. A connecting slide plate 6 is slidably connected to one side of the end connecting block 7. A longitudinal electric telescopic rod 10 is fixedly connected to the bottom of the connecting slide plate 6. The longitudinal electric telescopic rod 10 is slidably connected to the base plate 1. A slide rail plate 9 is fixedly connected to the bottom of the connecting slide plate 6. Several sliding claws 41 are slidably connected to the bottom of the slide rail plate 9.

[0022] In this embodiment, two electrode boxes with positive and negative electrodes are placed on the two middle layer plates 2 respectively. The diaphragm roll is installed on the rotating wheel frame 22 so that it can rotate and unwind. The horizontal electric telescopic rod 8 extends and drives the end connecting block 7, the connecting slide plate 6 and the longitudinal electric telescopic rod 10 to move. The connecting slide plate 6 drives the slide rail plate 9 and several sliding claws 41 to move above the two electrode boxes. Then the longitudinal electric telescopic rod 10 drives the connecting slide plate 6 to retract and drives the slide rail plate 9 and sliding claws 41 to move down. The corresponding sliding claws 41 can move to both sides by themselves. After clamping the electrode, they are reset to above the center plate 5.

[0023] The top of the center plate 5 is provided with several alternating first slide grooves 20 and second slide grooves 21. Bottom sliders 24 are installed in both the first slide grooves 20 and the second slide grooves 21. The bottom sliders 24 are slidably connected to the center plate 5. An end support rod 19 is slidably connected in the bottom sliders 24. The bottom sliders 24 in the first slide grooves 20 and the second slide grooves 21 are all at their ends that are far away from each other. A bearing rod 25 is slidably connected on the side of the bottom sliders 24 that is far away from the end support rod 19. The same pressure rod 16 is fixed to the end of the bearing rod 25 on the same side that is far away from the bottom slider 24. Bottom connecting rods 30 are fixedly connected to the bottom of each end support rod 19. The end of the bottom connecting rod 30 on the same side away from the end support rod 19 is slidably connected to the bottom mounting plate 26 through a sliding groove. A connecting rod 29 is fixedly connected to one side of the bottom mounting plate 26. One end of the connecting rod 29 is threadedly connected to a threaded rod 32 through a fixing block. One end of the threaded rod 32 is rotatably connected to a fixing plate 31. The fixing plate 31 is fixedly connected to the bottom of the center plate 5. A second motor 40 is provided on the side of the threaded rod 32 away from the fixing plate 31. The second motor 40 is fixedly connected to the bottom of the center plate 5 through a bracket. The output shaft of the second motor 40 is fixedly connected to the threaded rod 32.

[0024] A rotating wheel frame 22 is installed on the side of the center plate 5 near the side frame 3, and a support plate 11 is installed on the side of the center plate 5 away from the side frame 3. A mounting rod 13 is fixedly connected to one side of the support plate 11. A load-bearing slide plate 14 is slidably connected to the surface of the support plate 11. An internal slide 15 is slidably connected inside the mounting rod 13. An elastic clamp 23 is hinged to the end of the internal slide 15. A support spring 12 is fixedly connected between the load-bearing slide plate 14 and the mounting rod 13.

[0025] In this embodiment, the elastic clamp 23 is opened, and then the end of the diaphragm roll is pulled between the elastic clamp 23 and the bearing slide plate 14. It is then clamped by the elastic clamp 23 and the bearing slide plate 14. Then, the second motors 40 on both sides are turned on and rotated. The threaded rod 32 drives the connecting rod 29 to move. The connecting rod 29 drives the bottom mounting plate 26 and several bottom connecting rods 30 to move. The end support rod 19 and the bottom slider 24 driven by the bottom connecting rod 30 move, so that the end support rods 19 on both sides move towards each other, turning the diaphragm roll into a dense wave shape. The moving distance of the end support rod 19 can be set according to the specifications of the electrode.

[0026] Subsequently, the longitudinal electric telescopic rod 10 retracts to insert the electrode into each trough of the end support rod 19, thus enabling the simultaneous insertion of several positive and negative electrode plates at one time. At this time, the side of the electrode plate closest to the center plate 5 is supported by the bearing rod 25, but the edge of the diaphragm is in close contact with the center plate 5, so as to ensure that the diaphragm can cover the electrode plate in all directions.

[0027] Among them, a limiting groove 18 is fixedly connected to one side of the pressure rod 16, and a limiting rod 17 is opened on one side of the side plate 4. The limiting rod 17 surrounds the outer periphery of the pivot connecting the center plate 5 and the side plate 4, and the limiting groove 18 passes through the limiting rod 17 and is restricted by it.

[0028] In this embodiment, after the electrode is inserted, several sliding grippers 41 release the electrode, causing the internal slide 15 to move the elastic clamp 23 upward. Then, the center plate 5 rotates 90 degrees, causing several electrode sheets to stack above the bearing slide plate 14. Due to the limiting groove 18, when the limiting rod 17 rotates along the limiting groove 18, the radius of the limiting groove 18 becomes smaller. Therefore, at this time, the limiting groove 18 causes the pressure rod 16 and several bearing rods 25 to slide along the corresponding bearing rods 25, so that the bearing rods 25 are no longer located between several films, thus avoiding obstruction of the films during compression.

[0029] Among them, a first motor 27 is fixedly connected to one side of the bottom mounting plate 26, a winding wheel 28 is fixedly connected to the output shaft of the first motor 27, and a traction rope 33 is fixedly connected to the outer wall of the winding wheel 28.

[0030] The bottom mounting plate 26 has several evenly distributed positioning rods 39 fixed to its bottom. The bottom connecting rod 30 has a fixing ring installed near the bottom of the bottom mounting plate 26. The traction rope 33 will pass through the fixing ring at the bottom of the bottom mounting plate 26 in sequence, then wrap around the positioning rod 39 below it, and then pass through the fixing ring at the bottom of the next bottom mounting plate 26, and so on, so that it can only move along a specific path.

[0031] The bottom connecting rod 30 overlaps with the bottom mounting plate 26 and has an opening on the side near the first motor 27. The bottom mounting plate 26 has a hollow structure inside. An internal rotating rod 34 is provided between the two bottom connecting rods 30. The middle part of the internal rotating rod 34 is rotatably connected to the bottom mounting plate 26.

[0032] The two ends of the internal rotating rod 34 are provided with sequential retraction mechanisms arranged in a circumferential array, including inclined plate clamping rods 36 and two internal springs 35. The two internal springs 35 are located on both sides of the internal rotating rod 34, and the ends of the two internal springs 35 are respectively fixed to the bottom mounting plate 26 and the end of the inclined plate clamping rod 36. The top end of the internal rotating rod 34 is fixed to the upper inclined plate clamping rod 36 by a second traction rope 37. The bottom end of the internal rotating rod 34 is provided with a push rod 38 between the lower inclined plate clamping rod 36 and the lower inclined plate clamping rod 36. The push rod 38 is fixed to the inclined plate clamping rod 36.

[0033] In this embodiment, the end support rod 19 closest to the first motor 27 becomes the uppermost part. The first motor 27 drives the winding wheel 28 to rotate, and the winding wheel 28 winds the traction rope 33. Except for the bottom connecting rod 30 closest to the first motor 27, which can be pulled by the traction rope 33, the rest are locked by the upper inclined locking rod 36. Only when the first bottom connecting rod 30 moves down and squeezes the inclined locking rod 36 into the bottom mounting plate 26, and the push rod 38 squeezes the internal rotating rod 34 to rotate, and the top of the internal rotating rod 34 pulls the inclined locking rod 36 into retraction, can the second bottom connecting rod 30 be pulled, thereby achieving the effect of releasing the end support rods 19 sequentially from top to bottom.

[0034] After the end support rod 19 is fully retracted, the battery plates between the elastic clamp plate 23 and the bearing slide plate 14 are smoothed. The plates can be stacked as needed. The end support rod 19 can be reset manually after the traction rope 33 is released by winding the wheel 28. Alternatively, a plate can be added to the bottom of the bottom mounting plate 26 to make the end support rod 19 hollow. A spring is installed between the end support rod 19 and the added plate, and the spring will reset the rod itself.

[0035] Working principle: Two electrode boxes with positive and negative electrodes are placed on the two middle plates 2 respectively. The diaphragm roll is installed on the rotating wheel frame 22 so that it can rotate and unwind. The horizontal electric telescopic rod 8 extends and drives the end connecting block 7, the connecting slide plate 6 and the vertical electric telescopic rod 10 to move. The connecting slide plate 6 drives the slide rail plate 9 and several sliding claws 41 to move above the two electrode boxes. Then the vertical electric telescopic rod 10 drives the connecting slide plate 6 to retract and drives the slide rail plate 9 and sliding claws 41 to move down. The corresponding sliding claws 41 can move to both sides by themselves. After clamping the electrode, they are reset to above the center plate 5.

[0036] Open the elastic clamp 23 and then pull the end of the diaphragm roll between the elastic clamp 23 and the bearing slide plate 14. It is then clamped by the elastic clamp 23 and the bearing slide plate 14. Then the second motors 40 on both sides start to rotate, and drive the connecting rod 29 to move through the threaded rod 32. The connecting rod 29 drives the bottom mounting plate 26 and several bottom connecting rods 30 to move. The end support rod 19 and the bottom slider 24 driven by the bottom connecting rod 30 move, so that the end support rods 19 on both sides move towards each other, turning the diaphragm roll into a dense wave shape. The moving distance of the end support rod 19 can be set according to the specifications of the electrode.

[0037] Subsequently, the longitudinal electric telescopic rod 10 retracts to insert the electrode into each trough of the end support rod 19, thus enabling the simultaneous insertion of several positive and negative electrode plates at one time. At this time, the side of the electrode plate closest to the center plate 5 is supported by the bearing rod 25, but the edge of the diaphragm is in close contact with the center plate 5, so as to ensure that the diaphragm can cover the electrode plate in all directions.

[0038] After the electrode is inserted, several sliding jaws 41 release the electrode, causing the internal slide 15 to move the elastic clamp 23 upward. Then, the center plate 5 rotates 90 degrees, causing several electrode sheets to stack above the bearing slide plate 14. Due to the limiting groove 18, when the limiting rod 17 rotates along the limiting groove 18, the radius of the limiting groove 18 becomes smaller. Therefore, at this time, the limiting groove 18 causes the pressure rod 16 and several bearing rods 25 to slide along the corresponding bearing rods 25, so that the bearing rods 25 are no longer located between several films, thus avoiding obstruction of the film during compression.

[0039] At this time, the end support rod 19 on the side closest to the first motor 27 becomes the uppermost. The first motor 27 drives the winding wheel 28 to rotate, and the winding wheel 28 winds the traction rope 33. Except for the bottom connecting rod 30 closest to the first motor 27, which can be pulled by the traction rope 33, the rest are locked by the upper inclined locking rod 36. Only when the first bottom connecting rod 30 moves down and squeezes the inclined locking rod 36 into the bottom mounting plate 26, and the push rod 38 squeezes the internal rotating rod 34 to rotate, and the top of the internal rotating rod 34 pulls the inclined locking rod 36 into retraction, can the second bottom connecting rod 30 be pulled, thereby achieving the effect of releasing the end support rods 19 sequentially from top to bottom.

[0040] After the end support rod 19 is fully retracted, the battery plates between the elastic clamp plate 23 and the bearing slide plate 14 are smoothed. The plates can be stacked as needed. The end support rod 19 can be reset manually after the traction rope 33 is released by winding the wheel 28. Alternatively, a plate can be added to the bottom of the bottom mounting plate 26 to make the end support rod 19 hollow. A spring is installed between the end support rod 19 and the added plate, and the spring will reset the rod itself.

[0041] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
