Description

Technical Field

[0001] This invention belongs to the field of battery processing equipment technology, specifically relating to an automatic stacking machine for new energy power batteries. Background Technology

[0002] The automatic stacking machine for new energy power batteries is a core piece of equipment in the manufacturing of lithium-ion power battery cells. It is designed specifically for the stacking process of square aluminum shell, soft-pack power batteries and large energy storage cells. It is an automated special equipment that enables the precise alternating stacking of positive electrode sheets, negative electrode sheets and separators in the order of "positive electrode-separator-negative electrode-separator" to form bare cells. It is widely used in the fields of new energy vehicle power batteries and energy storage power stations.

[0003] In existing lithium-ion battery automatic stacking machines, the pressing mechanism uses two cylinders to drive each pressing blade to achieve the up-and-down pressing and back-and-forth movement. Since cylinder driving requires the installation of pneumatic pipelines, control cables, and corresponding valve components, the multiple independent cylinder driving scheme results in a large number of intersecting pipelines and auxiliary components inside the equipment, significantly encroaching on the limited internal space and increasing the integration difficulty and maintenance costs. In addition, with the high-frequency reciprocating motion of the pressing mechanism, the pipelines connecting the cylinders are prone to displacement and deformation due to dragging and shaking. In severe cases, this can intrude into the core stacking working area of ​​the equipment, interfering with the normal stacking of electrodes and separators, affecting stacking accuracy and product yield. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and reasonably designed automatic stacking machine for new energy power batteries in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions: An automatic stacking machine for new energy power batteries includes a machine body for controlling the overall operation of the equipment. The machine body integrates control units including, but not limited to, a PCB control motherboard and a microcontroller. A frame is installed on the upper surface of the machine body. A material picking mechanism for picking up materials is installed inside the frame. A material rack for storing electrode sheets is installed on the machine body to ensure that the material picking mechanism can accurately pick up materials in a designated area. A transfer mechanism for moving the stacked materials is installed on the machine body. The transfer mechanism is composed of a support, a motor, a lead screw, a guide rail, a support platform, and other structures. A guide mechanism for guiding the separator is installed inside the frame. An assembly device is provided on the transfer mechanism. A pressing device for pressing the stacked layers is provided on the transfer mechanism through the assembly device.

[0006] As a further optimization of the present invention, the pressing device includes a cylinder installed below the transfer mechanism. A pusher is fixedly connected to the piston rod of the cylinder. A guide frame for guidance is fixedly connected to the transfer mechanism. A protrusion is slidably connected to the inner wall of the guide frame. A mounting frame is fixedly connected to the surface of the protrusion. The cooperation between the protrusion and the guide frame can guide the movement direction of the mounting frame, so that the mounting frame moves along a predetermined direction when moving. A blocking block is fixedly connected to the upper surface of the mounting frame. A through hole is opened on the surface of the blocking block. A connecting frame is slidably connected to the inner wall of the through hole. A pressing knife for pressing the stacked layers is slidably connected to the connecting frame. The pressing knife is slidably mounted on the connecting frame by bolts. At the same time, the movement direction of the pressing knife can be guided by the bolt through hole on the surface of the pressing knife. A connecting column is slidably connected between the mounting frame and the pusher. The connecting column can connect the mounting frame and the pusher. When the pusher moves under the drive of the cylinder, it can cooperate with the connecting column to push the mounting frame towards the bearing platform of the transfer mechanism, thereby causing the mounting frame to feed towards the bearing platform.

[0007] As a further optimization of the present invention, a load-bearing plate is fixedly connected to the lower surface of the connecting frame, and a second spring is fixedly connected between the load-bearing plate and the blocking block. The force applied by the second spring to the load-bearing plate can constrain the position of the load-bearing plate in the non-stressed state. In addition, when the load-bearing plate loses external force, the second spring can push the load-bearing plate to reset.

[0008] As a further optimization of the present invention, the push frame is slidably connected to the surface of the transfer mechanism, the guide hole of the guide frame is L-shaped, the guide part of the connecting frame passes through the blocking block, the guide part of the connecting frame is located inside the mounting frame, the connecting column is slidably installed in the inclined hole on the push frame, and two limiting rings arranged vertically are fixedly connected to the surface of the connecting column. Both limiting rings are in movable contact with the surface of the push frame. The limiting rings can constrain the position of the connecting column to ensure that the connecting column moves on a predetermined horizontal plane.

[0009] As a further optimization of the present invention, the load-bearing plate is slidably connected to the inner wall of the mounting frame, the second spring is located inside the mounting frame, and there are two sets of the second spring, with two springs in each set. The two springs are arranged symmetrically with reference to the transverse axis of the load-bearing plate.

[0010] As a further optimization of the present invention, the connecting frame is provided with an adjustment device for adjusting the position of the pressure knife. The adjustment device includes a slide that is slidably installed inside the connecting frame. A blocking frame for sealing its opening is fixedly connected inside the connecting frame. A spring is fixedly connected between the blocking frame and the slide. The spring can apply a force to the slide under the action of the blocking frame, thereby constraining the position of the slide in the non-forced state. A connecting plate is fixedly connected to the side of the slide away from the blocking frame. A top plate for applying a force to the connecting plate is fixedly connected to the lower surface of the connecting plate. A positioning frame is fixedly connected to the surface of the connecting plate. A slider is fixedly connected to the lower surface of the positioning frame. A guide hole for adapting to the slider is opened on the surface of the pressure knife.

[0011] As a further optimization of the present invention, the slide extends through the side surface of the connecting frame, and the surface of the pressure knife is provided with a square hole larger than the size of the top plate. The top plate passes through the pressure knife through the square hole, so that the top plate can contact the support platform of the transfer mechanism when moving, and push the connecting plate under the restriction of the transfer mechanism. The positioning frame is in movable contact with the upper surface of the pressure knife, and the slider is slidably connected to the inner wall of the guide hole. The cooperation between the slider and the guide hole allows the slider to move the pressure knife in a specified direction through the guide hole when moving, thereby achieving the effect of adjusting the position of the pressure knife.

[0012] As a further optimization of the present invention, the assembly device includes a square sleeve fixed on the transfer mechanism. A connecting frame is fixedly connected to the surface of the square sleeve, and a fixing block is fixedly connected to the surface of the connecting frame. A limit frame is fixedly connected to the surface of the cylinder. A permanent magnet adapted to the fixing block is fixedly connected to the inner wall of the limit frame. The permanent magnet and the fixing block are magnetically connected. The fixing block is made of a material such as iron that can be attracted by the permanent magnet. Through the cooperation of the permanent magnet and the fixing block, the position of the connecting frame can be initially constrained when the operator fixes the connecting frame, so as to prevent the connecting frame from shaking and facilitate the operator to install the connecting frame.

[0013] As a further optimization of the present invention, the connecting frame and the fixing block are both inserted into the inner wall of the limiting frame, and there are two connecting frames and two limiting frames. The two connecting frames and the limiting frames are arranged symmetrically with reference to the axis of the transfer mechanism.

[0014] The beneficial effects of this invention are as follows: 1. Because the two sets of pressing knives used to press and stack materials are driven by two cylinders respectively, with the help of the precise mechanical linkage between the cylinders and the push frame and guide frame, each set of pressing knives only needs one cylinder to complete the forward and backward feeding positioning and up and down pressing actions simultaneously. This makes the timing control of the pressing knife action more precise and efficient. At the same time, this structure reduces the total number of cylinders while ensuring that the pressing knife has uniform pressing force and stable pressing accuracy on the stacked materials. It avoids the problem that the design of multiple independent cylinders would lead to a large number of pipelines and auxiliary components inside the equipment, which would occupy the usable space inside the equipment. In addition, with the movement of the pressing knife mechanism, the pipelines connected to the cylinders are prone to displacement and deformation, which may intrude into the stacking working area in severe cases and interfere with the normal stacking operation of the electrode and diaphragm.

[0015] 2. Because there is an adjustment device between the pressure knife and the connecting frame for adjusting the position of the pressure knife, when the connecting frame moves the pressure knife to reset, the connecting frame can cooperate with the top plate, connecting plate, positioning frame, slider and spring to move the pressure knife along the design direction, so that the edge of the pressure knife is separated from the diaphragm, avoiding the problem that the edge of the pressure knife is always in contact with the diaphragm when resetting, because its edge is relatively sharp and easily damages the diaphragm when resetting.

[0016] 3. Since the cylinder is mounted on the transfer mechanism through the assembly device, the transfer mechanism can drive the cylinder synchronously during the movement, so that the cylinder moves stably with the transfer mechanism and ensures that the pressing device always keeps in sync with the transfer mechanism.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example: Please refer to Figures 1-12 The automatic stacking machine for new energy power batteries includes a machine body 1. The machine body 1 integrates control units including but not limited to a PCB control motherboard and a microcontroller. A frame 2 is installed on the upper surface of the machine body 1. A material picking mechanism 3 for picking up materials is installed inside the frame 2. A material rack 4 for storing electrode sheets is installed on the machine body 1 to ensure that the material picking mechanism 3 can accurately pick up materials in a designated area. A transfer mechanism 5 for moving and stacking materials is installed on the machine body 1. The transfer mechanism 5 is composed of a bracket, motor, lead screw, guide rail, and bearing platform. A guide mechanism 6 for guiding the separator is installed inside the frame 2. An assembly device 7 is provided on the transfer mechanism 5. A pressing device 8 for pressing the stacked layers is provided on the transfer mechanism 5 through the assembly device 7.

[0021] Please see Figure 5 and Figure 6The pressing device 8 includes a cylinder 81 mounted below the transfer mechanism 5. A pusher 82 is fixedly connected to the piston rod of the cylinder 81. A guide frame 83 for guiding is fixedly connected to the transfer mechanism 5. A protrusion 84 is slidably connected to the inner wall of the guide frame 83. A mounting frame 85 is fixedly connected to the surface of the protrusion 84. The cooperation between the protrusion 84 and the guide frame 83 can guide the movement direction of the mounting frame 85, so that the mounting frame 85 moves along a predetermined direction when moving. A blocking block 86 is fixedly connected to the upper surface of the mounting frame 85. A through hole is opened on the surface of the blocking block 86, and the inner wall of the through hole slides... A connecting frame 87 is connected, and a pressing knife 88 for pressing the stacked layers is slidably connected to the connecting frame 87. The pressing knife 88 is slidably mounted on the connecting frame 87 by bolts. At the same time, the bolt through holes on the surface of the pressing knife 88 can guide the movement direction of the pressing knife 88. A connecting column 89 is slidably connected between the mounting frame 85 and the push frame 82. The connecting column 89 can connect the mounting frame 85 and the push frame 82. When the push frame 82 moves under the drive of the cylinder 81, it can cooperate with the connecting column 89 to push the mounting frame 85 towards the bearing platform of the transfer mechanism 5, thereby causing the mounting frame 85 to feed towards the bearing platform.

[0022] Please see Figure 6 and Figure 7 A load-bearing plate 810 is fixedly connected to the lower surface of the connecting frame 87. A second spring 811 is fixedly connected between the load-bearing plate 810 and the blocking block 86. The force applied by the second spring 811 to the load-bearing plate 810 can constrain the position of the load-bearing plate 810 in the non-stressed state. In addition, when the load-bearing plate 810 loses external force, the second spring 811 can drive the load-bearing plate 810 to reset.

[0023] Please see Figure 5 , Figure 6 , Figure 7 and Figure 8 The push frame 82 is slidably connected to the surface of the transfer mechanism 5. The guide hole of the guide frame 83 is L-shaped. The guide part of the connecting frame 87 passes through the shielding block 86. The guide part of the connecting frame 87 is located inside the mounting frame 85. The connecting column 89 is slidably installed in the inclined hole on the push frame 82. Two limiting rings arranged vertically are fixedly connected to the surface of the connecting column 89. Both limiting rings are in movable contact with the surface of the push frame 82. The limiting rings can constrain the position of the connecting column 89 to ensure that the connecting column 89 moves on a predetermined horizontal plane.

[0024] Please see Figure 5 , Figure 6 , Figure 7 and Figure 8 The load-bearing plate 810 is slidably connected to the inner wall of the mounting frame 85. The second spring 811 is located inside the mounting frame 85. There are two sets of the second spring 811, and each set contains two springs. The two springs 811 are arranged symmetrically with reference to the transverse axis of the load-bearing plate 810.

[0025] Please see Figure 9 and Figure 10 The connecting frame 87 is provided with an adjustment device 9 for adjusting the position of the pressure knife 88. The adjustment device 9 includes a slide 91 slidably installed inside the connecting frame 87. A blocking frame 92 for sealing its opening is fixedly connected inside the connecting frame 87. A spring 93 is fixedly connected between the blocking frame 92 and the slide 91. The spring 93 can apply force to the slide 91 under the action of the blocking frame 92, thereby constraining the position of the slide 91 in the non-forced state. A connecting plate 94 is fixedly connected to the side of the slide 91 away from the blocking frame 92. A top plate 95 for applying force to the connecting plate 94 is fixedly connected to the lower surface of the connecting plate 94. A positioning frame 96 is fixedly connected to the surface of the connecting plate 94. A slider 97 is fixedly connected to the lower surface of the positioning frame 96. A guide hole 98 adapted to the slider 97 is opened on the surface of the pressure knife 88.

[0026] Please see Figure 9 and Figure 10 The slide 91 penetrates the side surface of the connecting frame 87. The surface of the pressure knife 88 has a square hole larger than the size of the top plate 95. The top plate 95 passes through the square hole and penetrates the pressure knife 88, so that the top plate 95 can contact the support platform of the transfer mechanism 5 when it moves, and push the connecting plate 94 under the restriction of the transfer mechanism 5. The positioning frame 96 moves against the upper surface of the pressure knife 88. The slider 97 is slidably connected to the inner wall of the guide hole 98. The cooperation between the slider 97 and the guide hole 98 allows the slider 97 to move the pressure knife 88 in a specified direction through the guide hole 98 when it moves, thereby achieving the effect of adjusting the position of the pressure knife 88.

[0027] Please see Figure 11 and Figure 12 The assembly device 7 includes a square sleeve 71 fixed on the transfer mechanism 5. A connecting frame 72 is fixedly connected to the surface of the square sleeve 71. A fixing block 73 is fixedly connected to the surface of the connecting frame 72. A limit frame 74 is fixedly connected to the surface of the cylinder 81. A permanent magnet 75 adapted to the fixing block 73 is fixedly connected to the inner wall of the limit frame 74. The permanent magnet 75 and the fixing block 73 are magnetically connected. The fixing block 73 is made of a material such as iron that can be attracted by the permanent magnet 75. Through the cooperation of the permanent magnet 75 and the fixing block 73, the position of the connecting frame 72 can be initially constrained when the operator fixes the connecting frame 72, so as to prevent the connecting frame 72 from shaking and facilitate the operator to install the connecting frame 72.

[0028] Please see Figure 11 and Figure 12Both the connecting frame 72 and the fixing block 73 are inserted into the inner wall of the limiting frame 74. When the fixing block 73 is inserted into the limiting frame 74, the fixing block 73 abuts against the limiting frame 74 through the flanges on both sides, thereby bearing the weight applied by the limiting frame 74 and the cylinder 81. There are two connecting frames 72 and two limiting frames 74. The two connecting frames 72 and the two limiting frames 74 are arranged symmetrically with reference to the axis of the transfer mechanism 5. The arrangement of the two connecting frames 72 allows the operator to use the fixing block 73 and the limiting frame 74 to clamp the cylinder 81 from both sides when fixing it to the surface of the square sleeve 71, thereby improving the stability of the cylinder 81 after it is fixed.

[0029] It should be noted that, in use, the automatic stacking machine for new energy power batteries uses a guide mechanism 6 to pull the diaphragm to the surface of the carrier platform of the transfer mechanism 5 for pre-laying. The controller controls the cylinders 81 of the pressing devices 8 on both sides to start synchronously. The piston rod of the cylinder 81 extends to push the pusher 82 to move. The pusher 82 drives the mounting frame 85 to move synchronously through the connecting column 89. The mounting frame 85 slides along the L-shaped guide hole of the guide frame 83 through the protrusion 84, converting the linear motion of the cylinder 81 into a composite motion of the mounting frame 85 moving forward and backward toward the carrier platform plus pressing up and down. Then, through the blocking block 86 and the connecting frame 87, the pressing knife 88 is driven to move toward the stacking station. When the mounting frame 85 moves to the pressing station, the connecting frame 87 drives the pressing knife 88 to press the pre-laid diaphragm onto the surface of the carrier platform through the pre-tightening force of the load plate 810 and the second spring 811. Subsequently, the transfer mechanism 5 is activated, and its support platform, driven by the motor and lead screw, moves the compressed diaphragm horizontally to the left-side material picking station. When the support platform moves to the left-side material picking station, the left-side material picking mechanism 3 is activated, picking up the electrode sheet from the corresponding material rack 4 and accurately placing it on the diaphragm surface. After the electrode sheet is placed, the cylinder 81 of the right-side pressing device 8 reverses its action, passing through the pusher 82, connecting column 89, protrusion 84, and L... The transmission mechanism of the guide frame 83 drives the right pressure knife 88 to exit the stacking station. After the right pressure knife 88 is completely withdrawn, the right cylinder 81 immediately moves forward, driving the right pressure knife 88 to quickly return to the pressing station and press the top layer of the stack. Through the above alternating actions, it is ensured that the right pressure knife 88 always presses the top layer of the stack when the left station is working, preventing the diaphragm and electrode from shifting. As the stacking operation continues, the total thickness of the stack gradually increases. When the pressure knife 88 presses the stack, it is constrained by the thickness and moves upward, causing the connecting frame 87 and the load plate 810 to slide upward synchronously. This causes the spring 811 to be squeezed and produce elastic deformation. The elastic force of the spring 811 automatically compensates for the change in the thickness of the stack, so that the pressure knife 88 always maintains a stable pressing force. Similarly, when the support platform moves the stack to the right material picking station for electrode placement, the left pressure knife 88 performs the same alternating pressing and automatic thickness compensation actions as the right pressure knife 88. During the feeding of the pressing knife 88 toward the support platform, the connecting frame 87 synchronously drives the adjustment device 9 to move. In the initial state, the spring 93 pushes the connecting plate 94 to maintain the initial position through the slide 91, and the top plate 95 moves downward synchronously with the connecting plate 94. When the top plate 95 contacts the surface of the support platform, it is rigidly constrained by the support platform and pushes the connecting plate 94 and the slide 91 to slide, compressing the spring 93. While the slide 91 moves, it drives the positioning frame 96 and the slider 97 to move synchronously. The slider 97 slides obliquely along the guide hole 98 on the pressing knife 88, thereby driving the pressing knife 88 to move outward and unfold, ensuring that the pressing knife 88 is in the maximum unfolded state when it is pressed in place, so as to achieve full pressing of the edge of the stacked pieces. When the cylinder 81 reverses and drives the connecting frame 87 to reset, the top plate 95 disengages from the support platform, the spring 93 loses its compression force and rebounds to reset, pushing the slide 91, connecting plate 94 and top plate 95 to move; the slide 91 simultaneously drives the positioning frame 96 and slider 97 to move in opposite directions, the slider 97 slides obliquely along the guide hole 98, pulling the pressure knife 88 to move inward and retract, so that the edge of the pressure knife 88 completely detaches from the stacking surface during the process of exiting the stacking station, avoiding scratching the diaphragm or causing the electrode to shift; When the carrier platform of the transfer mechanism 5 moves from the left workstation to the right workstation, the carrier platform drives the square sleeve 71. The square sleeve 71, together with the connecting frame 72, the fixing block 73 and the limiting frame 74, drives the pressing device 8 to move with the carrier platform, ensuring that the pressing device 8 is always located on the workstation of the carrier platform. Because the two sets of pressing knives 88 used to press the stacked materials are driven by two cylinders 81 respectively, with the help of the precise mechanical linkage between the cylinders 81, the pusher 82, and the guide frame 83, each set of pressing knives 88 only needs one cylinder 81 to complete the forward and backward feeding positioning and up and down pressing actions simultaneously, making the timing control of the pressing knives 88 more precise and efficient. At the same time, this structure reduces the total number of cylinders 81 while ensuring that the pressing force of the pressing knives 88 on the stacked materials is uniform and the pressing accuracy is stable. This avoids the problem that the design of multiple independent cylinders 81 would lead to a large number of pipelines and auxiliary components inside the equipment, which would take up the usable space inside the equipment. In addition, with the movement of the pressing knives 88 mechanism, the pipelines connected to the cylinders 81 are prone to displacement and deformation, which may intrude into the stacking working area in severe cases and interfere with the normal stacking operation of the electrodes and diaphragms. In addition, since an adjustment device 9 for adjusting the position of the pressure knife 88 is provided between the pressure knife 88 and the connecting frame 87, when the connecting frame 87 moves the pressure knife 88 to reset, the connecting frame 87 can cooperate with the top plate 95, connecting plate 94, positioning frame 96, slider 97 and spring 93 to move the pressure knife 88 along the design direction, so that the edge of the pressure knife 88 is separated from the diaphragm, avoiding the problem that the edge of the pressure knife 88 is always in contact with the diaphragm when resetting, because its edge is relatively sharp and easily damages the diaphragm when resetting.

[0030] Among them, the machine body 1, the controller, material handling mechanism 3, transfer mechanism 5, guide mechanism 6 and cylinder 81 inside the machine body 1 are all existing technologies, and their control and working principles will not be elaborated here; for the connection parts between the parts, the connection methods such as welding, bolt fixing, interference fit can be selected according to the needs of the connection position of the parts; at the same time, the materials used for the parts can be selected according to their usage requirements.

[0031] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
