Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and particularly to a flipping and pushing device and a material stacking device. Background Art

[0002] During the production process of battery components, at least two battery cells need to be stacked and assembled together.

[0003] During the stacking process of battery cells, a certain pressure needs to be applied to the stacked battery cells to ensure the stacking quality. The traditional stacking method is through a robot. This method cannot control the pressure, and long-term use of the robot to press the battery cells may cause deviation in the accuracy of the robot.

[0004] Therefore, a new technical solution is needed that can apply pressure to the battery cells during the stacking process to ensure the stacking quality of the battery cells. Summary of the Invention

[0005] The object of the present invention is to provide a flipping and pushing device and a material stacking device to solve the problems in the prior art that when stacking and pressing battery cells by a robot, the pressure cannot be controlled and it is easy to cause deviation in the accuracy of the robot.

[0006] To achieve the above object, the present invention provides a flipping and pushing device, which includes: a frame, a flipping frame capable of flipping relative to the frame, and a loading frame provided on the flipping frame for carrying materials;

[0007] Wherein, the frame is arranged to be capable of moving horizontally, the flipping frame is arranged to be capable of flipping between a horizontal position and a vertical position, and the loading frame is arranged to be capable of moving relative to the flipping frame in a direction perpendicular to the rotation axis of the flipping frame; wherein, a limiting support for limiting the material is provided on one side of the loading frame, and when the flipping frame flips to the vertical position, the limiting support supports below the material carried by the loading frame;

[0008] When the flipping frame is in the horizontal position, the loading frame carries the material. When the flipping frame flips to the vertical position, the loading frame moves downward relative to the flipping frame. When the loading frame moves down to a predetermined position, the material on the loading frame is carried by the receiving component below and the limiting support is located in the gap of the receiving component. When the frame moves towards the released material, the loading frame applies pressure to the material.

[0010] Among them, the motor is installed at the bottom of the flipping frame, the rack is installed at the bottom of the material loading frame, a slide rail is arranged between the material loading frame and the flipping frame, and the rotation of the gear can drive the material loading frame to move along the slide rail through the rack.

[0011] Preferably, the flipping and pushing device further includes a pressing mechanism arranged on one side of the material loading frame opposite to the limit support member and a sizing mechanism arranged at opposite ends of the material loading frame. The pressing mechanism is used to press the material carried by the material loading frame onto the limit support member, and the sizing mechanisms at both ends are arranged to size the position of the material from both ends of the material.

[0014] The flipping and pushing device is arranged to place materials on the support bars of the material receiving and stacking device at least twice;

[0015] Among them, after the material loading frame of the flipping and pushing device flips and moves downward, the materials carried are released on the support bars. The limit support member of the material loading frame is located in the gap between the support bars, and the frame of the flipping and pushing device moves in the direction towards the baffle to press the materials.

[0016] Preferably, the material receiving and stacking device further includes a pressing plate located at one end of the support bars opposite to the baffle and a pressing plate driving mechanism for driving the pressing plate to move. After the flipping and pushing device places materials on the support bars at least twice and presses the materials, the pressing plate driving mechanism drives the pressing plate to move in the direction towards the baffle to press the materials;

[0017] The material receiving and stacking device further includes a baffle driving mechanism connected to the baffle for driving the baffle to move back and forth along the direction of the support bars;

[0018] Before the materials on the support bars press on the baffle, the baffle driving mechanism drives the baffle to be in a predetermined position. The flipping and pushing device presses the materials on the baffle in the predetermined position. After the pressing plate presses the materials, the baffle driving mechanism drives the baffle to retreat a predetermined distance away from the materials.

[0019] Preferably, the material stacking device further includes a resisting block located on the side of the baffle away from the material and a resisting air cylinder connected to the resisting block. When the resisting air cylinder drives the resisting block to extend, the resisting block prevents the baffle from retreating. When the resisting air cylinder drives the resisting block to retract, the baffle driving mechanism can drive the baffle to retreat.

[0020] Preferably, the material stacking device further includes a moving device for driving the material receiving and stacking device to move along the length direction of the support bar;

[0021] Each time the turnover and pushing device places a material on the material receiving and stacking device, the moving device drives the material receiving and stacking device to move a predetermined distance in a direction away from the turnover and pushing device.

[0022] Preferably, the material stacking device further includes a feeding device for placing materials on the material loading rack. The feeding device includes a manipulator and a feeding grasping mechanism installed on the manipulator. Among them, the feeding grasping mechanism includes two feeding jaws that can move towards or away from each other and two clamping plates that can move towards or away from each other. When the two feeding jaws grasp the material from opposite sides of the material, the two clamping plates press the material from opposite ends of the material;

[0023] and / or,

[0024] The material stacking device further includes a discharging device. The discharging device includes a discharging rack, a discharging grasping mechanism, and a discharging driving mechanism. The discharging grasping mechanism is movably installed on the discharging rack.

[0025] Preferably, the material stacking device further includes a strapping device for strapping a strip-shaped component on the materials stacked on the material receiving and stacking device.

[0026] Preferably, the strip-shaped component includes an annular belt;

[0027] The strapping device includes a strapping machine frame, two tensioning components arranged on the strapping machine frame, and a driving mechanism for driving the two tensioning components to move away from and close to each other. Among them, each tensioning component includes a tensioning frame and a positioning component, a belt supporting mechanism, and a pressing mechanism arranged on the tensioning frame;

[0028] The positioning component is used to position the tensioning frame on the materials carried by the material receiving and stacking device. The belt supporting mechanism is arranged to be able to support the annular belt and disengage from the annular belt;

[0029] When the annular belt to be bundled is wound around the outer sides of the two tensioning frames, the belt supporting mechanism supports the annular belt, and the driving mechanism drives the two tensioning components to move away from each other to tension the annular belt;

[0030] When the positioning member is positioned on the material, the belt supporting mechanism disengages from the annular belt, and the pressing mechanism presses the annular belt so that the annular belt moves downward to be sleeved on the material carried by the material receiving and stacking device.

[0031] Preferably, the belt-shaped member includes a flexible strip;

[0032] The strapping device further includes a guide plate provided on the strapping machine frame. The guide plate is provided with a horizontal guide groove. When the material to be strapped leans against the guide plate, the opening of the guide groove faces the material, and the flexible strip can pass through the guide groove to strap the material.

[0033] In the technical solution provided by the present invention, when the loading rack releases the material on the receiving component in a manner of flipping and moving downward, and then the machine frame drives the loading rack to move to apply pressure to the released material, pressing the material during the stacking process can ensure the stacking quality of the material, thereby avoiding the defect that the method of applying pressure when stacking materials by a robot in the prior art cannot control the pressure and may cause deviation of the robot's accuracy.

Detailed implementation manners

[0048] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0049] It should be noted that, without conflict, the implementation manners in the present invention and the features in the implementation manners can be combined with each other.

[0050] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. Additionally, "inner" and "outer" refer to the inner and outer of the contour of each component itself.

[0051] Furthermore, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0052] The present invention provides a flipping and pushing device, as Figures 1 - 3 shown. The flipping and pushing device 2 includes: a frame 21, a flipping frame 22 capable of flipping relative to the frame 21, and a loading frame 23 provided on the flipping frame 22 for carrying materials.

[0053] Among them, the frame 21 is arranged to be capable of moving horizontally, the flipping frame 22 is arranged to be capable of flipping between a horizontal position and a vertical position, and the loading frame 23 is arranged to be capable of moving relative to the flipping frame 22 in a direction perpendicular to the axis of rotation of the flipping frame 22. Among them, a limiting support member 231 for limiting the materials is provided on one side of the loading frame 23, and when the flipping frame 22 flips to the vertical position, the limiting support member 231 supports below the materials carried by the loading frame 23.

[0054] When the flipping frame 22 is in the horizontal position, the loading frame 23 carries the materials. When the flipping frame 22 flips to the vertical position, the loading frame 23 moves downward relative to the flipping frame 22. When the loading frame 23 moves down to a predetermined position, the materials in the loading frame 23 are carried by the receiving component below and the limiting support member 231 is located in the gap of the receiving component. When the frame 21 moves towards the released materials, the loading frame 23 applies pressure to the materials.

[0055] The flipping and pushing device 2 provided by the present invention is suitable for stacking battery cells (and can also be used for stacking other materials). Figure 1As shown, a set of battery cells 7 are carried on the loading rack 23. When the loading rack 23 is flipped to release the carried battery cells onto the receiving component for stacking, the rack 21 drives the loading rack 23 to move to apply pressure to the released battery cells. In this way, pressing the battery cells during the stacking process can ensure the stacking quality of the battery cells and avoid the defects that the pressure application method when using a robot for stacking in the prior art cannot control the pressure and may cause deviation in the robot's accuracy.

[0056] In a specific embodiment of the present invention, as Figure 1 shown, the rack 21 includes mounting frames 211 located at opposite ends of the flipping frame 22, and opposite ends of the flipping frame 22 are respectively rotatably mounted on the mounting frames 211;

[0057] The flipping and pushing device 2 further includes guide rails 28 respectively corresponding to the mounting frames 211 and a transverse movement driving mechanism 25 for driving the mounting frames 211. The transverse movement driving mechanism 25 drives the mounting frames 211 to move along the guide rails 28.

[0058] The rack 21 is provided with a horizontal limiting member 212 and a vertical limiting member 214; wherein, the horizontal limiting member 212 is arranged to be able to expand and contract. When the horizontal limiting member 212 is in the extended state, the horizontal limiting member 212 can limit the flipping frame 22 in the horizontal position. When the horizontal limiting member 212 retracts, the flipping frame 22 can rotate from the horizontal position to the vertical position; the vertical limiting member 214 is used to limit the flipping frame 22 when the flipping frame 22 is flipped to the vertical position.

[0059] Specifically, the horizontal limiting member 212 and the vertical limiting member 214 are respectively provided on the two mounting frames 211 of the rack 21. Among them, the horizontal limiting member 212 is connected to a telescopic cylinder 213. When the flipping frame 22 is in the horizontal position, the horizontal limiting members 212 at both ends of the flipping frame 22 extend to keep the flipping frame 22 in the horizontal position. When the flipping frame 22 is flipped, the telescopic cylinder 213 controls the horizontal limiting member 212 to retract, so that the flipping frame 22 can be flipped to the vertical position until it contacts the vertical limiting member 214.

[0060] In this embodiment, the flipping and pushing device 2 further includes a pressing mechanism provided on the side of the loading rack 23 opposite to the limiting and supporting member 231 and a regulating mechanism provided at opposite ends of the loading rack 23. The pressing mechanism is used to press the material carried on the loading rack 23 onto the limiting and supporting member 231, and the regulating mechanisms at both ends are arranged to regulate the position of the material from both ends of the material.

[0061] Specifically, as Figure 2As shown, each of the alignment mechanisms at the opposite ends of the material rack 23 includes a first pressing plate 232 and a first air cylinder 233. The first air cylinder 233 drives the first pressing plate 232 to move towards the material carried by the material rack 23, aligning the material from both ends. The pressing mechanism on the side of the material rack 23 opposite to the limit support 231 includes a second pressing plate 234 and a second air cylinder 235. The second air cylinder 235 can drive the second pressing plate 234 to move to press on the material carried by the material rack 23 or move away from the material carried by the material rack 23.

[0062] The flipping and pushing device 2 further includes a lifting mechanism 26 for driving the material rack 23 to move relative to the flipping frame 22, as Figure 3 shown. The lifting mechanism 26 includes a motor 261, a gear 262 driven by the motor 261, and a rack 263 engaged with the gear 262;

[0063] wherein, the motor 261 is installed at the bottom of the flipping frame 22, the rack 263 is installed at the bottom of the material rack 23, and a slide rail 221 (refer to Figure 2 ) is provided between the material rack 23 and the flipping frame 22. The rotation of the gear 262 can drive the material rack 23 to move along the slide rail 221 through the rack 263.

[0064] After the flipping frame 22 flips from the horizontal position towards the vertical position or during the process of flipping from the horizontal position towards the vertical position, the lifting mechanism 26 drives the material rack 23 to move downward along the slide rail 221 until the material in the material rack 23 is carried by the receiving component below.

[0065] Preferably, the flipping and pushing device 2 further includes a flipping mechanism 24 for controlling the flipping of the flipping frame 22. The flipping mechanism 24 is installed on the mounting frame 211 at one end of the flipping frame 22.

[0066] The flipping and pushing device 2 further includes a material inductor 27 for sensing whether the material on the material rack 23 is in place. After the material inductor 27 senses that the material is in place, the flipping mechanism 24 controls the flipping of the flipping frame 22 and controls the downward movement of the material rack 23.

[0067] According to another aspect of the present invention, a material stacking device is further provided. It should be noted here that the material stacking device described in this application is designed to be suitable for stacking battery cells. Of course, when the material stacking device is used to stack other materials, it can be adaptively modified without departing from the scope of this application.

[0068] As Figure 4Said material stacking equipment comprises a material receiving and stacking device 3 and the flipping and pushing device 2 as described above;

[0069] In one embodiment, reference Figure 5 and Figure 6 The material receiving and stacking device 2 comprises a material receiving component for receiving materials and a baffle 32 located at one end of the material receiving component, and the material receiving component comprises at least two support bars 31;

[0070] The flipping and pushing device 2 is configured to place materials at least twice on the support bar 31 of the material receiving and stacking device 3;

[0071] Among them, after the loading rack 23 of the flipping and pushing device 2 flips and moves downward, the material carried is released on the support bar 31, the limiting support 231 of the loading rack 23 is located in the gap between the support bars 31, and the frame 21 of the flipping and pushing device 2 moves toward the direction of the baffle 32 to push the material.

[0072] The material receiving and stacking device 3 further includes a pressing plate 34 located at an end of the support bar 31 opposite to the baffle 32 and a pressing plate driving mechanism 35 for driving the pressing plate 34 to move. After the flipping and pushing device 2 places materials on the support bar 31 at least twice and pushes the materials, the pressing plate driving mechanism 35 drives the pressing plate 34 to move toward the baffle 32 and press the materials.

[0073] The material receiving and stacking device further comprises a baffle driving mechanism 33 connected to the baffle 32 and used for driving the baffle 32 to move back and forth along the direction of the support bar 31;

[0074] Before the material on the support bar 31 is pressed onto the baffle 32, the baffle driving mechanism 33 drives the baffle 32 to be in a predetermined position, and the flipping and pushing device 2 pushes the material onto the baffle 32 in the predetermined position. After the pressing plate 34 presses the material, the baffle driving mechanism 33 drives the baffle 32 to retreat a predetermined distance away from the material.

[0075] Preferably, the material stacking equipment also includes a stop block 38 located on the side of the baffle 32 facing away from the material and a stop cylinder 37 connected to the stop block 38. When the stop cylinder 37 drives the stop block 38 to extend, the stop block 38 prevents the baffle 32 from retreating, and can support the baffle 32 against the pressure from the material. When the stop cylinder 37 drives the stop block 38 to retract, a space is formed on the side of the baffle 32 facing away from the material for retreating, so that the baffle drive mechanism 33 can drive the baffle 32 to retreat.

[0076] In this embodiment, the baffle driving mechanism 33 is set to retract the baffle 32 by a predetermined distance. The purpose is to place a first cover plate at one end of the stacked battery cell assembly close to the baffle 32 when using this material stacking device to stack battery cells. When the pressing plate driving mechanism 35 drives the pressing plate 34 to move towards the battery cell assembly, a second cover plate can be placed between the pressing plate 34 and the battery cell assembly, and the movement of the pressing plate 34 can press the second cover plate against one end of the battery cell assembly close to the pressing plate 34.

[0077] The material stacking device further includes a moving device 6 for driving the material receiving and stacking device 2 to move along the length direction of the support bar 31, as Figure 5 shown;

[0078] Each time the turnover and pushing device 2 places a material on the material receiving and stacking device 3, the moving device 6 drives the material receiving and stacking device 3 to move a predetermined distance in a direction away from the turnover and pushing device 2. This predetermined distance is at least the length occupied by the material released by the turnover and pushing device 2 (for example, the thickness of a group of battery cells released by the turnover and pushing device 2). By moving the material receiving and stacking device 3 a predetermined distance in a direction away from the turnover and pushing device 2, space can be vacated for the turnover and pushing device 2 to continue placing materials on the material receiving and carrying device 3.

[0079] The material stacking device further includes a feeding device 1 for feeding materials onto the material loading rack 23. The feeding device 1 includes a manipulator 11 and a feeding grasping mechanism 12 installed on the manipulator 11. Among them, the feeding grasping mechanism 12 includes two feeding jaws 121 that can move towards or away from each other and two clamping plates 122 that can move towards or away from each other. When the two feeding jaws 121 grasp the material from opposite sides of the material, the two clamping plates 122 press the material from opposite ends of the material; among them, a bent portion can be provided at the end of the feeding jaw 121, and this bent portion can support the grasped material from below. The two feeding jaws 121 and the two clamping plates 122 can be driven by air cylinders respectively, or can also be driven by other mechanisms.

[0080] After the feeding grasping mechanism 12 grasps the material, the manipulator 11 moves to a predetermined position, and the feeding grasping mechanism 12 releases the grasped material onto the material loading rack 23 of the turnover and pushing device 2.

[0081] The material stacking device further includes a strapping device 4 for strapping a strip-shaped component onto the materials stacked on the material receiving and stacking device 3.

[0082] The strip-shaped component strapped by the strapping device 4 may include an annular belt 8;

[0083] as Figure 8As shown, the strapping device 4 includes a strapping machine frame 41, two tensioning components 42 arranged on the strapping machine frame 41, and a driving mechanism for driving the two tensioning components 42 to move away from and close to each other. Among them, each tensioning component 42 includes a tensioning frame 421, and a positioning component 424, a belt supporting mechanism, and a pressing mechanism arranged on the tensioning frame 421;

[0084] The positioning component 424 is used to position the tensioning frame 421 on the material carried by the material receiving and stacking device 3. The belt supporting mechanism is arranged to be able to support the annular belt 8 and disengage from the annular belt 8; among them, the positioning component 424 is preferably a columnar member that cooperates with the jack on the material.

[0085] When the annular belt 8 to be strapped is wound around the outside of the two tensioning frames 421, the belt supporting mechanism supports the annular belt 8, and the driving mechanism drives the two tensioning components 42 to move away from each other to tension the annular belt;

[0086] When the positioning component 424 is positioned on the material, the belt supporting mechanism disengages from the annular belt 8, and the pressing mechanism presses down, so that the annular belt 8 moves down to be sleeved on the material carried by the material receiving and stacking device.

[0087] Among them, the driving mechanism for driving the tensioning component can be a tensioning cylinder 43 connected to the tensioning frame 421 of one of the tensioning components 42. The tensioning cylinder 43 drives one tensioning component 42 to move away to tension the annular belt 8.

[0088] Among them, as Figure 9 shown, the belt supporting mechanism includes a belt supporting member 422 and a belt supporting cylinder 423 for driving the belt supporting member 422 to move; before tensioning the annular belt 8, the belt supporting cylinder 423 drives the belt supporting member 44 to move to a first preset position, so that the belt supporting member 422 can support the annular belt 8. When the pressing mechanism presses down the annular belt 8, the belt supporting cylinder 423 drives the belt supporting member 422 to move to a second preset position, and the belt supporting member disengages from the tensioned annular belt 8.

[0089] Preferably, as Figure 9 shown, the belt supporting member 422 is an L-shaped structure including a vertical plate and a horizontal plate. The horizontal plate extends from the lower end of the vertical plate towards the tensioning component 42, and the driving end of the belt supporting cylinder 423 is connected to the upper end of the vertical plate;

[0090] After the tensioning component 42 tensions the annular belt and the belt supporting cylinder 423 drives the belt supporting member 422 to move a predetermined distance in a direction away from the tensioning component 42, the belt supporting member 422 disengages from the annular belt.

[0091] The pressing mechanism includes a pressing block 425 and a pressing cylinder 426 for driving the pressing block 425 to move downward. After the pressing cylinder 426 drives the pressing block 425 to move downward, during the downward movement of the pressing block 425, the annular belt is pushed to be sleeved on the material below.

[0092] During specific operation, first, the belt supporting cylinder 423 drives the belt supporting component 422 to move to the first preset position. At this first preset position, the lifting component 422 can lift the annular belt 8 to be bundled. Then, the tensioning cylinder 43 drives the tensioning components 42 to move away from each other to tension the annular belt 8. The lifting cylinder 44 drives the strapping rack 41 to descend, so that the tensioning components 42 are positioned on the material on the receiving and stacking device 3 through the positioning component 424. Then, the belt supporting cylinder 423 drives the belt supporting component 422 to move to the second preset position, so that the belt supporting component 422 disengages from the annular belt 8. The pressing cylinder 426 drives the pressing block 425 to move downward to press the annular belt 8 onto the material below.

[0093] The strip-shaped component bundled by the strapping device 4 may also include a flexible strip.

[0094] The strapping device 4 includes a guide plate 45 provided on the strapping rack 41. The guide plate 45 is provided with a horizontal guide groove 451. When the material to be bundled leans against the guide plate 45, the opening of the guide groove 451 faces the material, and the flexible strip can pass through the guide groove 451 to bundle the material.

[0095] The material stacking device further includes a blanking device 5, as Figure 10 shown. The blanking device 5 includes a blanking rack 51, a blanking grasping mechanism and a blanking driving mechanism. Among them, the blanking grasping mechanism includes two blanking jaws 52 for grasping the material. The blanking grasping mechanism is movably installed on the blanking rack 51. After the blanking grasping mechanism grasps the material from the receiving and stacking device 3, the blanking driving mechanism 53 drives the blanking grasping mechanism to move to a predetermined position to release the material.
