Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a dual-power hot-pressing and restraining capacity-forming integrated machine. Background Art

[0002] In the lithium battery production process, hot pressing, restraint, and capacity integration equipment are generally used to form the lithium battery. This process activates the chemical reaction within the lithium battery, thereby increasing its capacity and cycle life.

[0003] Existing hot pressing restraint capacity integration equipment usually includes an outer frame, multiple layer plate assemblies, a push plate assembly and a screw nut drive assembly. The outer frame includes a left end plate and a right end plate that are arranged opposite to each other on the left and right sides, and two guide rods that are symmetrically arranged front to back are provided between the left end plate and the right end plate. The layer plate assembly includes layers, and the layers of the multiple layer plate assemblies are sequentially spaced from right to left between the left end plate and the right end plate, and the two ends of the layers are respectively slidably mounted on the outer periphery of the two guide rods. The push plate assembly is located between the right end plate and the layer plate of the first layer plate assembly, and the push plate assembly includes a push plate, and the two ends of the push plate are respectively slidably mounted on the outer periphery of the two guide rods, and the push plate contacts the layer plate of the first layer plate assembly, and the layer plate of the last layer plate assembly contacts the left end plate. The screw-nut drive assembly includes a drive motor, a reducer, a gear phase, two screws and two nuts. The reducer and the gearbox are arranged on the side of the right end plate away from the left end plate. The drive motor is arranged on the reducer. The two screws are respectively arranged between the left end plate and the right end plate and are symmetrically arranged front to back. The two nuts are respectively engaged with the two screw threads, and the two ends of the push plate are respectively sleeved on the outer periphery of the two nuts. In actual application, after the lithium batteries are placed one by one between the layers of the two adjacent layer plate assemblies, the drive motor drives the two screws to rotate through the reducer and the gearbox, so that the two nuts can drive the push plate to move to the left along the two guide rods, and then push the layer plate of the first layer plate assembly to move to the left along the two guide rods. Under the action of the lithium battery, the layers of the remaining layer plate assemblies except the layer plate of the last layer plate assembly can be pushed to the left in turn, so that the distance between the layers of the two adjacent layer plate assemblies is reduced, thereby achieving restraint and pressurization of the battery.

[0004] In the above structure, since a screw-nut driving assembly is used to push the layers of the multiple layer assemblies to the left to restrain and pressurize the lithium battery, the pressure of this structure for restraining and pressurizing the lithium battery is usually not too large due to the rated load limitations of the reducer, screw and nut. Therefore, when the lithium battery requires a greater pressure for restraint and pressurization, the device cannot meet the usage requirements. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the utility model provides a dual-power hot pressing restraint capacity integrated machine, which adopts dual-power components to restrain and pressurize lithium batteries, which can increase the pressure of restraining and pressurizing lithium batteries, thereby meeting the use requirements of lithium batteries that require greater pressure for restraint and pressurization.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] The cam is secured to the left and right sides of the frame and is designed to be pivotally connected to the frame by two hinged tabs, each of which has a plurality of latches, each of which has a latching mechanism, and a latching mechanism for locking the cam in place. The cam is secured to the left and right sides of the frame and is designed to lock the cam in place. The two ends of the push plate are respectively slidably mounted on the outer periphery of the two guide rods, and also include a pre-stressing power assembly, a spring plate assembly and a wedge power assembly. The pre-stressing power assembly is used to drive the push plate to move left and right along the two guide rods. The spring plate assembly is located between the left end plate and the layer plate of the last layer plate assembly, and the two ends of the spring plate assembly are respectively slidably mounted on the outer periphery of the two guide rods. The wedge power assembly is located between the spring plate assembly and the left end plate, and the two ends of the wedge power assembly are respectively slidably mounted on the outer periphery of the two guide rods. The wedge power assembly is used to drive the spring plate assembly to move left and right along the two guide rods.

[0008] The beneficial effects of the present invention are as follows: the present invention drives the push plate to move to the left along the two guide rods through the pre-stressing power assembly, the spring plate assembly and the wedge power assembly, thereby pushing the layer plates of multiple layer plate assemblies to move to the left along the two guide rods in turn, so that the lithium battery can be restrained and pressurized for the first time, and the spring plate assembly is driven to move to the right along the two guide rods through the wedge power assembly, thereby pushing the layer plates of the remaining layer plate assemblies except the layer plates of the first layer plate assembly to move to the right in turn, so that the lithium battery can be restrained and pressurized for the second time. By adopting dual power assemblies to restrain and pressurize the lithium battery, the pressure of restraining and pressurizing the lithium battery can be increased compared with the existing technology, thereby being able to meet the use requirements of lithium batteries that require greater pressure for restraining and pressurizing.

The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0032] Please refer to Figure 1 、 Figure 2 、 Figures 4 to 6 An embodiment of the present invention provides a dual-power hot pressing and restraining capacity-forming integrated machine, including an outer frame 10, a plurality of layer plate assemblies 20, an adjustment drive assembly 30, a push plate assembly 40, a pre-pressing power assembly 50, a spring plate assembly 60 and a wedge block power assembly 70.

[0033] The outer frame 10 includes a left end plate 11 and a right end plate 12 that are arranged opposite to each other in the left and right directions. Two connecting rod assemblies that are symmetrically arranged in the front and back directions, two guide rods 14 that are symmetrically arranged in the front and back directions, and two guide shafts 15 that are symmetrically arranged in the front and back directions are provided between the left end plate 11 and the right end plate 12. The connecting rod assembly includes two connecting rods 13 that are spaced apart in an upper and lower direction. One end of the connecting rod 13 is provided on the side of the left end plate 11 close to the right end plate 12, and the other end of the connecting rod 13 is provided on the side of the right end plate 12 close to the left end plate 11. The two guide rods 14 and the two guide shafts 15 are both located between the two connecting rod assemblies. One end of the guide rod 14 is provided on the side of the left end plate 11 close to the right end plate 12, and the other end of the guide rod 14 is provided on the side of the right end plate 12 close to the left end plate 11. The two guide shafts 15 are respectively located below the two guide rods 14 and are respectively provided in parallel with the two guide rods 14. One end of the guide shaft 15 is disposed on a side of the left end plate 11 close to the right end plate 12 , and the other end of the guide shaft 15 is disposed on a side of the right end plate 12 close to the left end plate 11 .

[0034] A plurality of layer plate assemblies 20 are located between the left end plate 11 and the right end plate 12 and between the two connecting rod assemblies. The number of layer plate assemblies 20 can be set according to actual conditions.

[0035] Combine Figure 8 and Figure 9 As shown, the layer plate assembly 20 specifically includes a layer plate 21, a first elastic pressure block 22, a first conductive structure 23, a second elastic pressure block 25, and a second conductive structure 24. The layer plates 21 of the plurality of layer plate assemblies 20 are sequentially spaced and arranged between the left end plate 11 and the right end plate 12 from right to left. The ends of the layer plates 21 are respectively sleeved on the outer circumferences of the two guide rods 14, and the layer plates 21 can move left and right along the two guide rods 14.

[0036] In this embodiment, two mounting members 211 are respectively provided at both ends of the layer plate 21, and the mounting members 211 partially protrude from the bottom end of the layer plate 21. Two layer plate hangers 212 are respectively provided at the ends of the two mounting members 211 away from the layer plate 21. The layer plate hangers 212 are provided with hanger through holes 2121, and the two layer plate hangers 212 are respectively sleeved on the outer periphery of the two guide rods 14 through their respective hanger through holes 2121. The inner wall of the hanger through holes 2121 is provided with multiple rolling body structures at intervals along the circumference, and the multiple rolling body structures are in rolling contact with the outer peripheral surfaces of the corresponding guide rods 14. During the movement of the layer plate 21, the two layer plate hangers 212 can be driven by the layer plate 21 to move along the two guide rods 14 respectively, thereby driving the rolling body structures to move along the corresponding guide rods 14 in a rolling manner. Multiple rolling body structures move along the corresponding guide rod 14 in a rolling manner, thereby providing support for the movement of the corresponding layer plate hanger 212, thereby improving the smoothness of the movement of the layer plate hanger 212, and further improving the smoothness of the movement of the layer plate 21, improving the stability of the first and second pressurization of the lithium battery, and improving the quality of the lithium battery. There is rolling friction between the rolling body structure and the outer peripheral surface of the guide rod 14, so the friction force is small and the noise is low.

[0037] In this embodiment, there are four rolling element structures, which are respectively arranged on the top and bottom ends of the inner wall of the mounting hole 2121, the side close to the layer plate 21, and the side away from the layer plate 21. The rolling element structure includes two rolling elements 2122 arranged side by side. The rolling elements 2122 are preferably rollers. It is understood that the rolling element 2122 can also be a rotating bearing, such as a deep groove ball bearing. The rolling element structure and the number of rolling elements 2122 can be adjusted according to actual conditions.

The second elastic pressing block 25 is used to press the negative electrode of the lithium battery located on the right side of the layer plate 21 onto the PCB board 235 of the first conductive structure 23 of the adjacent layer plate assembly 20 to ensure the electrical connection between the negative electrode of the lithium battery located on the right side of the layer plate 21 and the first conductive structure 23 of the adjacent layer plate assembly 20. The PCB board 235 is used to be electrically connected to an external power supply through a wire, and the external power supply can charge and discharge the corresponding lithium battery through the PCB board 235.

The bottoms of the two second connecting plates 483 are each provided with two third cam channels 4833, each inclined in the same direction as the second cam channels 4832. Two third cam followers 471 are each provided at one end of the two second locking blocks 47. The two third cam followers 471 engage with and move along the corresponding third cam channels 4833. The first cam follower 4831 of the second connecting plate 483 is located between the second cam channel 4832 at the top of the second connecting plate 483 and the third cam channel 4833 at the bottom of the second connecting plate 483.

[0055] In the initial state, the two first cam followers 4831 are respectively located in one end of the two first cam channels 4821 close to the cylinder 481, the two second cam followers 461 are respectively located in the top end of the two second cam channels 4832, and the two third cam followers 471 are respectively located in the top end of the two third cam channels 4833. At this time, the first clamping members 462 of the two first locking blocks 46 are respectively located in the two first push plate grooves 4121, and the second clamping members 472 of the two second locking blocks 47 are respectively located in the two third push plate grooves 4171. When it is necessary to lock the push plate 41 on the two guide rods 14 and the two guide shafts 15, the cylinder 4 is used. 81 drives the two locking block connecting rods 4811 to move toward the direction close to the cylinder 481, thereby driving the two first connecting plates 482 to move toward the direction close to the cylinder 481. The movement of the two first connecting plates 482 can drive the two first cam followers 4831 to move along the corresponding first cam channels 4821 respectively until the two first cam followers 4831 are respectively located in the end of the corresponding first cam channels 4821 away from the cylinder 481. Since the first cam channels 4821 are inclined upward, the two second connecting plates 483 can be driven upward by the two first cam followers 4821. The two second connecting plates 483 The upward movement can respectively drive the second cam followers 461 of the two first locking blocks 46 to move along the corresponding second cam channels 4832, and the third cam followers 471 of the two second locking blocks 47 to move along the corresponding third cam channels 4833, until the second cam followers 461 of the two first locking blocks 46 are respectively located in the bottom ends of the corresponding second cam channels 4832, and the third cam followers 471 of the two second locking blocks 47 are respectively located in the bottom ends of the corresponding third cam channels 4833. Since the two second cam channels 4832 and the two third cam channels 4833 are inclined toward the direction close to the cylinder 481, the two The second cam followers 461 of the first locking blocks 46 can respectively drive the two first locking blocks 46 to move toward the two guide rods 14 so that the first clamping members 462 of the two first locking blocks 46 respectively extend from the corresponding first push plate grooves 4121 and respectively engage with the guide rod clamping grooves 1421 of the two guide rods 14, and the third cam followers 471 of the two second locking blocks 47 can respectively drive the two second locking blocks 47 to move toward the two guide shafts 15 so that the second clamping members 472 of the two second locking blocks 47 respectively extend from the corresponding third push plate grooves 4171 and respectively engage with the guide shaft clamping grooves 1511 of the two guide shafts 15. Figure 12As shown, locking of the push plate 41 on the two guide rods 14 and the two guide shafts 15 is achieved in this way. When the push plate 41 needs to be unlocked, the two lock block connecting rods 4811 are driven by the cylinder 481 to move in the direction away from the cylinder 481, thereby driving the two first connecting plates 482 to move in the direction away from the cylinder 481. The movement of the two first connecting plates 482 can drive the two first cam followers 4831 to move along the corresponding first cam channels 4821 respectively, until the two first cam followers 4831 are respectively located in the end of the corresponding first cam channels 4821 close to the cylinder 481. Since the first cam channels 4821 are inclined upward, the two first cam followers 4831 can respectively drive the two second connecting plates 483 to move downward. The downward movement of the two second connecting plates 483 can respectively drive the second cam followers 461 of the two first locking blocks 46 to move along the corresponding second cam channels 4832, and the third cam followers 471 of the two second locking blocks 47 to move along the corresponding third cam channels 4833.

[0056] The pre-pressing power assembly 50 is used to drive the push plate 41 to move left and right along the two guide rods 14 and the two guide shafts 15. The left and right movement of the push plate 41 can drive the first heat insulation plate 42, the two first locking blocks 46, the two second locking blocks 47, and the locking block driving module 48 to move left and right. In actual application, after the lithium batteries are placed one by one between the layers 21 of two adjacent layer assembly 20, when the pre-pressing power assembly 50 drives the push plate 41 to move left along the two guide rods 14 and the two guide shafts 15, the push plate 41 can push the layer 21 of the first layer assembly 20 to move left. Under the action of the lithium battery, the layer 21 of the remaining layer assembly 20 can be pushed to the left in turn, so that the distance between the layer 21 of the two adjacent layer assembly 20 is reduced, thereby achieving the first restraint and pressurization of the lithium batteries. At the same time, during the movement of the layer 21 of the layer assembly 20, since the distance between the layer 21 of the two adjacent layer assemblies 20 is reduced, the first elastic pressing block 22 and the second elastic pressing block 25 will be squeezed by the layer 21 of the adjacent layer assembly 20 respectively. Under the action of the elastic force of the first elastic pressing block 22 and the second elastic pressing block 25 themselves, the positive electrode of the lithium battery located on the left side of the layer 21 can be pressed onto the PCB board 235 of the second conductive structure 24 of the adjacent layer assembly 20 through the first elastic pressing block 22, and the negative electrode of the lithium battery located on the right side of the layer 21 can be pressed onto the PCB board 235 of the first conductive structure 23 of the adjacent layer assembly 20 through the second elastic pressing block 25.

The rotation of the transmission rod 52 drives the driving sprockets 53 of the two chain units, thereby driving the driven sprockets 54 and transmission chains 55 of the two chain units. The rotation of the transmission chains 55 of the two chain units drives the push plate 41 to move left and right. The use of chain units for transmission reduces production costs compared to the existing method of using a screw and nut for transmission.

The interior of the base 71 is formed between the base cover panel 715, the bottom panel 713, the first side panel 714 and the two second side panels 716. The two first openings mentioned above are respectively formed between the two second side panels 716 and the base cover panel 715 and the bottom panel 713. The box body 72 is arranged at one end of the base cover panel 715 and the bottom panel 713. The second opening mentioned above is formed between one end of the base cover panel 715 and one end of the bottom panel 713. The connecting piece 711 is arranged at the top of the base cover panel 715 and the box body 72.

[0069] The drive module includes a drive motor 751, a reducer 751, a gear transmission module, a screw 771, and a nut 772. The housing 72 partially protrudes from the bottom end of the base 71. The drive motor 751 and reducer 752 are both located below the base 71. The reducer 752 is located at the end of the housing 72 near the base 71. The drive motor 751 is mounted on the reducer 752, and the output end of the drive motor 751 is connected to the input end of the reducer 752. The gear transmission module is located within the housing 72, and the output end of the reducer 752 extends into the housing 72 and is connected to the gear transmission module. Screw 771 is located within base 71. One end of screw 771 is rotatably mounted on the inner wall of the other end of base 71, i.e., first side plate 714, via a screw bearing seat. The other end of screw 771 extends into housing 72 and is connected to the gear transmission module. Nut 772 is threadedly engaged with screw 771, and V-shaped push block 73 is sleeved around the outer periphery of nut 772. Drive motor 751 is used to rotate screw 771 via reducer 752 and the gear transmission module, thereby driving nut 772 to move back and forth, and in turn, V-shaped push block 73 to move back and forth.

[0070] In this embodiment, the gear transmission module includes a first transmission gear 761, a second transmission gear 762, and a third transmission gear 763. The first transmission gear 761 is mounted on the outer periphery of the output end of the reducer 752. The third transmission gear 763 is located above the first transmission gear 761 and mounted on the outer periphery of the other end of the screw rod 771. The second transmission gear 762 is located between the first transmission gear 761 and the third transmission gear 763 and is respectively meshed with the first transmission gear 761 and the third transmission gear 763. The reducer 752 can drive the first transmission gear 761 to rotate, thereby driving the second transmission gear 762 to rotate, and further driving the third transmission gear 793 to rotate, and further driving the screw rod 771 to rotate.

[0071] In actual use, in the initial state, the end of the V-shaped push block 73 away from the box body 72 is flush with one end of the two wedge blocks 74. First, the two lifting beams 16 are driven by the adjustment drive assembly 30 to move to adjust the positions of the PCB boards 235 of the first conductive structure 23 and the PCB boards 235 of the second conductive structure 24 of the plurality of layer assemblies 20. Then, the lithium batteries are placed one by one between the layers 21 of two adjacent layer assemblies 20, with the positive electrodes of the lithium batteries in contact with the PCB board 235 of the second conductive structure 24 of the layer assembly 20 located to the left of the lithium battery, and the negative electrodes of the lithium batteries in contact with the PCB board 235 of the first conductive structure 23 of the layer assembly 20 located to the right of the lithium battery.

[0072] Then, the pre-stressing power assembly 50 drives the push plate 41 to move to the left along the two guide rods 14 and the two guide shafts 15. The push plate 41 can push the layer plate 21 of the first layer plate assembly 20 to move to the left along the two guide rods 14. Under the action of the lithium battery, the layer plates 21 of the remaining layer plate assemblies 20 can be pushed to the left along the two guide rods 14 in turn. Among them, the movement of the layer plate 21 of the last layer plate assembly 20 can push the second heat insulation plate 62, the pressure plate 61, and the first spring mounting plate 63 to move to the left along the two guide rods 14 and the two guide shafts 15. In this way, the distance between the layer plates 21 of the two adjacent layer plate assemblies 20 can be reduced, thereby realizing the first restraint and pressurization of the lithium battery. Then, the pre-stressing power assembly 50 stops driving the push plate 41 to move. At this time, the pressurization elastic member 65 is in a compressed state. The pressurization elastic member 65 can apply pressure to the pressure plate 61. The pressure sensor 66 can detect the pressure applied to the pressure plate 61. This pressure is the pressure for the first restraint and pressurization of the lithium battery. During the movement of the layer 21 of the layer assembly 20, the positive electrode of the lithium battery located on the left side of the layer 21 can be pressed onto the PCB board 235 of the second conductive structure 24 of the adjacent layer assembly 20 through the first elastic pressing block 22, and the negative electrode of the lithium battery located on the right side of the layer 21 can be pressed onto the PCB board 235 of the first conductive structure 23 of the adjacent layer assembly 20 through the second elastic pressing block 25. Then the locking block driving module 48 drives the two first locking blocks 46 to move respectively toward the direction close to the two guide rods 14, and the two second locking blocks 47 to move respectively toward the direction close to the two guide shafts 15, so that the first clamping members 462 of the two first locking blocks 46 are respectively extended from the corresponding first push plate grooves 4121 and respectively engage with the guide rod clamping grooves 1421 of the two guide rods 14, and the second clamping members 472 of the two second locking blocks 47 are respectively extended from the corresponding third push plate grooves 4171 and respectively engage with the guide shaft clamping grooves 1511 of the two guide shafts 15, so that the push plate 41 is locked on the two guide rods 14 and the two guide shafts 15.

[0073] Then, the driving module drives the V-shaped push block 73 to move backward, thereby pushing the two wedge blocks 74 away from each other. In the process of the two wedge blocks 74 moving away from each other, the wedge block 74 on the right can push the second spring mounting plate 64 to move to the right, thereby pushing the pressure plate 61 and the second heat insulation plate 62 to move to the right along the two guide rods 14 and the two guide shafts 15 through the pressurized elastic member 65, thereby driving the layer 21 of the last layer assembly 20 to move to the right. Since the push plate 41 has been locked on the two guide rods 14 and the two guide shafts 15, under the action of the lithium battery, the last layer assembly 20 is The movement of the plates 21 of each plate assembly 20 drives the plates 21 of the remaining plate assemblies 20, except for the first plate assembly 20, to move rightward along the two guide rods 14 in sequence. This further reduces the distance between the plates 21 of two adjacent plate assemblies 20, thereby achieving a second restraint and pressurization of the lithium battery. The drive module then stops driving the V-shaped push block 73 backward. The pressure applied by the pressurizing elastic member 65 on the pressure plate 61 at this time is detected by the pressure sensor 66. This pressure is the pressure for the second restraint and pressurization of the lithium battery. Because the wedge cover 742 of the left wedge 74 is in contact with the left end plate 11, as the two wedges 74 move away from each other, the left wedge 74 can push the entire wedge power assembly 70 to move rightward along the two guide rods 14. The corresponding lithium battery is then charged and discharged by an external power supply through the PCB board 235 of the multiple plate assemblies 20, thereby achieving the formation of the lithium battery.

[0074] The present invention is provided with a pre-stressing power assembly 50, a spring plate assembly 60 and a wedge power assembly 70. The pre-stressing power assembly 50 drives the push plate 41 to move to the left along the two guide rods 14 and the two guide shafts 15, thereby pushing the layer plates 21 of multiple layer plate assemblies 20 to move to the left along the two guide rods 14 in turn, so that the lithium battery can be restrained and pressurized for the first time. The wedge power assembly 70 drives the spring plate assembly 60 to move to the right along the two guide rods 14, thereby pushing the layer plates 21 of the remaining layer plate assemblies 20 except the layer plate 21 of the first layer plate assembly 20 to move to the right in turn, so that the lithium battery can be restrained and pressurized for the second time. By adopting dual power assemblies to restrain and pressurize the lithium battery, the pressure of restraining and pressurizing the lithium battery can be increased compared with the existing technology, thereby being able to meet the use requirements of the lithium battery that requires greater pressure for restraining and pressurizing. At the same time, before the spring plate assembly 60 is driven to move to the right by the wedge power assembly 70, the push plate 41 is locked on the two guide rods 14 and the two guide shafts 15. This will not push the push plate 41 to move to the right, thereby ensuring the pressure accuracy of the second restraint pressurization.

[0075] In addition, two connecting chains are provided between the push plate 41 and the pressure plate 61 of the present invention. One end of the connecting chain is provided on the side of the push plate 41 close to the first layer assembly 20, and the other end of the connecting chain is provided on the side of the pressure plate 61 close to the last layer assembly 20. The ends of the two layer hangers 212 away from the layer 21 are respectively connected to the two connecting chains. When the layer plate 21 of the layer plate assembly 20 is pushed to the left by the push plate 41 to restrain and pressurize the lithium battery for the first time, and the layer plate 21 of the layer plate assembly 20 is pushed to the right by the spring plate assembly 60 to restrain and pressurize the lithium battery for the second time, the section of the connecting chain between the two adjacent layer plate assemblies 20 is in a relaxed state. When the push plate 41 is driven to the right by the pre-compression power assembly to return to the initial position, and the spring plate assembly is driven to the left by the wedge power assembly to return to the initial position, the two connecting chains can drive the layers 21 of multiple layer plate assemblies 20 to return to the initial position, thereby releasing the constraint on the lithium battery. After the layers 21 of the multiple layer plate assemblies 20 return to the initial position, the section of the connecting chain between the two adjacent layer plate assemblies 20 is in a tensioned state.
