Description

Technical Field

[0001] This invention relates to bag-making equipment, and more particularly to a high-efficiency lithium battery electrode bag-making machine. Background Technology

[0002] Currently, in the process of making electrode bags for lithium battery electrodes, the bag-making machine needs to place the lower separator at the heat-sealing station, place the lithium battery electrode (except for the tab part of the electrode) on the lower separator, and then cover the lithium battery electrode with the upper separator. After heat sealing and cutting, the electrode bag is formed. However, in the existing operation, heat sealing and cutting are carried out on two platforms. That is, after heat sealing on the heat-sealing platform, a traction mechanism is used to pull one side of the upper and lower separators to move the part containing the lithium battery electrode to the cutting platform for cutting. At this time, during the process of pulling the upper and lower separators, the part of the upper and lower separators that contains the lithium battery electrode is easily stretched and deformed. Moreover, the lithium battery electrode moves relative to the upper and lower separators but cannot be accurately moved into place, affecting the cutting accuracy. In addition, each operation can only perform heat sealing or cutting separately, which is inefficient. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a high-efficiency lithium battery electrode bag making machine, which can improve cutting accuracy and efficiency.

[0004] The objective of this invention is achieved through the following technical solution:

[0006] Two mounting areas; the two mounting areas are arranged alternately along the Z-axis;

[0007] Processing area; the processing area is located between the two installation areas, and the processing area has heat sealing stations and cutting stations arranged sequentially and at intervals along the X direction;

[0008] Fixed base;

[0009] Two supporting and traction mechanisms are respectively arranged in the two installation areas. Each supporting and traction mechanism includes a base, a base drive structure, an operating platform, a platform lifting drive structure, a first pressure plate, a pressure plate lifting drive structure, a second pressure plate, and a bidirectional drive structure. The operating platform extends into the processing area and is used to support the upper separator, lithium battery electrode sheet, and lower separator. The operating platform is mounted on the base via the platform lifting drive structure. The platform lifting drive structure is used to drive the operating platform to move along the Y direction. The base is mounted on the fixed seat. The base drive structure is used to drive the base to move along the X direction, thereby linking the operating platform to move between the heat sealing station and the cutting station. The first and second pressure plates are arranged sequentially at intervals along the X-axis and are both used to press the upper and lower diaphragms onto the operating platform. The first pressure plate is mounted on the base via a pressure plate lifting drive structure, and one side of the first pressure plate extends into the processing area and is located directly above the operating platform. The pressure plate lifting drive structure is used to drive the first pressure plate to move along the Y-axis. The second pressure plate is mounted on the base via a bidirectional drive structure. The bidirectional drive structure is used to drive the second pressure plate to move along the Y-axis. The bidirectional drive structure is also used to drive the second pressure plate to move along the Z-axis, so that the second pressure plate extends out of the mounting area and faces the operating platform or retracts into the corresponding mounting area.

[0010] A heat-sealing mechanism; the heat-sealing mechanism is used to heat-seal and bond the upper separator and the lower separator along the edge of the lithium battery electrode on the operating platform; the bonding portion of the upper separator and the lower separator is formed as an adhesive part;

[0011] A cutting mechanism; the heat sealing mechanism and the cutting mechanism are arranged alternately along the X direction; the cutting mechanism is used to cut the upper diaphragm and the lower diaphragm along the edge of the adhesive part to form an electrode bag containing lithium battery electrode sheets.

[0012] Furthermore, the base is mounted on the fixed seat via a guide structure; the guide structure includes a guide rail extending along the X direction and a guide groove that movably inserts into the guide rail.

[0013] Furthermore, the base drive structure includes a rotary motor, a lead screw, and a lead screw nut; the body of the rotary motor is mounted on the fixed base; the lead screw is driven by the output shaft of the rotary motor; the lead screw nut is fitted over the lead screw and fixedly connected to the base.

[0014] Furthermore, the bidirectional drive structure includes a lifting cylinder and a telescopic cylinder; the cylinder body of the telescopic cylinder is mounted on the base, and the telescopic rod of the telescopic cylinder is parallel to the Z-direction and fixedly connected to the cylinder body of the lifting cylinder; the telescopic rod of the lifting cylinder is parallel to the Y-direction and is drivenly connected to the second pressure plate.

[0015] Furthermore, the heat sealing mechanism includes a heat sealing element, a first heating component, and a heat sealing element driving structure; the first heating component is used to heat the heat sealing element; the heat sealing element has a downwardly protruding hot-pressing flange, and the trajectory shape of the hot-pressing flange is the same as the edge shape of the lithium battery electrode except for its tab portion; the heat sealing element driving structure is used to drive the heat sealing element to move along the Y direction.

[0016] Furthermore, the cutting mechanism includes a cutter, a cutter drive structure, and a second heating component; the second heating component is used to heat the cutter; the blade of the cutter faces downward; the trajectory shape of the blade of the cutter is the same as the edge shape of the adhesive part; the cutter drive structure is used to drive the cutter to move along the Y direction.

[0017] Furthermore, the high-efficiency lithium battery electrode bag making machine also includes a frame, a mounting plate, a mounting plate drive structure, and a traction roller assembly and a pressing mechanism, both mounted on the mounting plate. The traction roller assembly is used for the upper diaphragm to be wound around. The mounting plate drive mechanism is used to drive the mounting plate to move along the X direction, so as to pull the upper diaphragm above or away from the operating platform in conjunction with the traction roller assembly. The pressing mechanism is used to push the upper diaphragm located on the operating platform towards the operating platform. The heat sealing mechanism and the cutting mechanism are both mounted on the mounting plate, and the traction roller assembly, the pressing mechanism, the heat sealing mechanism, and the cutting mechanism are arranged sequentially along the arrangement direction of the heat sealing station and the cutting station.

[0018] Furthermore, the pressing mechanism includes a pressure roller, a support, and a pressure roller driving mechanism; the pressure roller is pivotally connected to the support; the pressure roller driving mechanism is used to drive the support to move along the Y direction.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This invention comprises a heat-sealing mechanism, a cutting mechanism, and two support and traction mechanisms positioned in two separate installation areas. Each support and traction mechanism includes a base, a base drive structure, an operating platform, a platform lifting drive structure, a first pressure plate, a pressure plate lifting drive structure, a second pressure plate, and a bidirectional drive structure. Thus, the two operating platforms are positioned at the heat-sealing station and the cutting station, respectively, allowing for simultaneous heat-sealing and cutting operations using both mechanisms. Furthermore, when the operating platforms at the heat-sealing and cutting stations need to be interchanged, for the support and traction mechanism located at the heat-sealing station: the corresponding pressure plate lifting drive structure and bidirectional drive structure respectively drive the first and second pressure plates to press the upper and lower separators on both sides of the lithium battery electrode onto the operating platform; for the support and traction mechanism located at the cutting station: the bidirectional drive structure retracts the second pressure plate, and... The platform lifting drive structure lowers the operating platform, while the pressure plate lifting drive structure raises the first pressure plate, thus creating space between the first pressure plate and the operating platform at the heat sealing station. Subsequently, two base drive structures drive two bases to move in opposite directions, allowing the two operating platforms at the heat sealing and cutting stations to be interchanged. At this point, the heat sealing and cutting mechanisms can cycle synchronously for heat sealing and cutting, improving efficiency. Simultaneously, during the transfer of the operating platform at the heat sealing station, the first and second pressure plates move synchronously with the operating platform under the linkage of the bases, transferring the lithium battery electrode to the cutting station. Here, the first and second pressure plates press against opposite sides of the lithium battery electrode, preventing the portion of the lithium battery electrode wrapped by the upper and lower separators from being stretched and preventing the lithium battery electrode from shifting relative to the upper and lower separators, thus ensuring cutting accuracy.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] like Figure 1-3 The high-efficiency lithium battery electrode bag making machine shown includes a processing area, a fixed base 10, a heat sealing mechanism 30, a cutting mechanism 40, two mounting areas, and two supporting and traction mechanisms 20; wherein,

[0027] The two installation areas and the processing area are arranged alternately along the Z-axis, that is, they are arranged in the order of installation area, processing area, and installation area along the Z-axis.

[0028] Two supporting and traction mechanisms 20 are respectively set in two installation areas; the two supporting and traction mechanisms 20 adopt the same structure. Here, only the detailed structure of one of the traction supporting and traction mechanisms 20 is described. Specifically, the supporting and traction mechanism 20 includes a base 21, a base drive structure 22, an operating platform 23, a platform lifting drive structure 24, a first pressure plate 25, a pressure plate lifting drive structure 26, a second pressure plate 27, and a bidirectional drive structure 28. Specifically, the operating platform 23 is mounted on the base 21 through the platform lifting drive structure 24. The platform lifting drive structure 24 is used to drive the operating platform 23 to move along the Y direction, that is, to drive the operating platform 23 to perform lifting and lowering movements. The base 21 is mounted on the fixed seat 10. The base drive structure 22 is used to drive the base 21 to move along the X direction, so as to move the operating platform 23 between the heat sealing station and the cutting station. The first pressure plate 25 and the second pressure plate 27 are arranged alternately along the X direction, and both can be used to press the upper diaphragm 60 and the lower diaphragm onto the operating platform 23. The first pressure plate 25 is mounted on the base 21 through the pressure plate lifting drive structure 26, and one side of the first pressure plate 25 extends into the processing area and is located directly above the operating platform 23. The pressure plate lifting drive structure 26 is used to drive the first pressure plate 25 to move along the Y direction, so that the first pressure plate 25 moves closer to the operating platform 23 or away from the platform, thereby pressing or releasing the upper diaphragm 60 and the lower diaphragm accordingly. The bidirectional drive structure 28 is used to drive the second pressure plate 27 to move along the Y direction. The bidirectional drive structure 28 is also used to drive the second pressure plate 27 to move along the Z direction, so that the second pressure plate 27 extends out of the installation area and faces the operating platform 23 or retracts the second pressure plate 27 into the corresponding installation area.

[0029] Heat sealing mechanism 30; heat sealing mechanism 30 is used to heat seal and bond the upper separator 60 and the lower separator along the edge of the lithium battery electrode on the operating platform 23; the part where the upper separator 60 and the lower separator are bonded is formed as an adhesive part;

[0030] The cutting mechanism 40, the heat sealing mechanism 30, and the cutting mechanism 40 are arranged alternately along the X direction; the cutting mechanism 40 is used to cut the upper separator 60 and the lower separator along the edge of the adhesive part to form an electrode bag containing lithium battery electrode sheets.

[0031] Based on the above structure, when using this high-efficiency lithium battery electrode bag making machine, the upper separator 60 on the outer upper separator roll and the lower separator on the outer lower separator roll are pulled out, and both the upper separator 60 and the lower separator pass between the operating platforms 23 of the two supporting traction mechanisms 20 and the first pressure plate 25; the two operating platforms 23 are adjusted to be placed on the heat sealing station and the cutting station respectively. At this time, the heat sealing mechanism 30 and the cutting mechanism 40 can be used to perform heat sealing and cutting operations respectively, improving efficiency. The electrode bag containing the lithium battery electrode formed by cutting can be removed by external equipment; when cutting is required after heat sealing, the operating platform 23 is... The supporting and traction mechanism 20 located at the heat-sealing station: The first pressure plate 25 is driven by the pressure plate lifting drive structure 26 to press the upper diaphragm 60 and the lower diaphragm onto the operating platform 23. The second pressure plate 27 is driven by the bidirectional drive structure 28 to press the upper diaphragm 60 and the lower diaphragm onto the operating platform 23. At this time, the first pressure plate 25 and the second pressure plate 27 press against both sides of the lithium battery electrode sheet. For the supporting and traction mechanism 20 located at the cutting station: The corresponding platform lifting drive structure 24 is used to lower the operating platform 23, and the pressure plate lifting drive structure 26 is used to raise the first pressure plate 25, thus ensuring the operating platform at the cutting station is properly positioned. The distance H1 between platform 23 and the first pressure plate 25 in the Y direction is greater than the total height H2 of the operating platform 23 and the first pressure plate 25 at the heat sealing station (or greater than the total height H3 of the operating platform 23 and the second pressure plate 27; it should be noted that in actual use, if the total height H2 is greater than the total height H3, then the distance H1 is greater than the total height H2, and vice versa). A bidirectional drive structure 28 is used to retract the second pressure plate 27 into the corresponding installation area, thus avoiding the preceding support and traction mechanism 20. Then, two base drive structures 22 are used to drive the two bases 21 to move in opposite directions, which can smoothly connect the heat sealing station and the cutting station. The two operating platforms 23 are swapped, so that the heat sealing mechanism 30 and the cutting mechanism 40 can be used synchronously to continue to heat seal and cut the upper diaphragm 60 and the lower diaphragm on the two operating platforms 23 respectively, thereby improving efficiency. At the same time, the operating platform 23, the first pressure plate 25 and the second pressure plate 27 located at the heat sealing station move together with the base 21 to the cutting station. At this time, the first pressure plate 25 and the second pressure plate 27 press on the opposite sides of the lithium battery electrode, which can prevent the part of the upper diaphragm 60 and the lower diaphragm that wraps the lithium battery electrode from deforming, and prevent the lithium battery electrode from shifting relative to the upper diaphragm 60 and the lower diaphragm, thereby ensuring the cutting accuracy.

[0032] Furthermore, throughout the entire process, the two supporting and traction mechanisms 20 interchange positions, eliminating the need for additional space to accommodate them; and the base only needs to move along the X direction, without needing to move along the Y direction or other directions, thus saving space.

[0033] Specifically, the base 21 is mounted on the fixed seat 10 via a guide structure; the guide structure includes a guide rail 50 extending along the X direction and a guide groove that is movably inserted into the guide rail 50, thereby improving the movement stability of the base 21.

[0034] More specifically, the base drive structure 22 includes a rotary motor, a lead screw, and a lead screw nut; the body of the rotary motor is mounted on the fixed base 10; the lead screw is driven by the output shaft of the rotary motor; the lead screw nut is fitted around the lead screw and fixedly connected to the base 21; thus, when the rotary motor starts, the output shaft of the rotary motor drives the lead screw to rotate, thereby driving the base 21 to move in conjunction with the lead screw nut. At this time, the accuracy of the movement path can be further improved through the cooperation of the lead screw and the lead screw nut.

[0035] The aforementioned base drive structure 22 can also be a pneumatic cylinder, hydraulic cylinder, etc.

[0036] Furthermore, the bidirectional drive structure 28 includes a lifting cylinder 281 and a telescopic cylinder 282; the cylinder body of the telescopic cylinder 282 is mounted on the base 21, and the telescopic rod of the telescopic cylinder 282 is parallel to the Z-direction and fixedly connected to the cylinder body of the lifting cylinder 281; the telescopic rod of the lifting cylinder 281 is parallel to the Y-direction and is drivenly connected to the second pressure plate 27; or, the bidirectional drive structure 28 is implemented with the following structure: the bidirectional drive structure 28 includes a lifting cylinder 281 and a telescopic cylinder 282; the cylinder body of the lifting cylinder 281 is mounted on the base 21, and the telescopic rod of the lifting cylinder 281 is parallel to the Y-direction and connected to the cylinder body of the telescopic cylinder 282; the telescopic rod of the telescopic cylinder 282 is parallel to the Z-direction and is drivenly connected to the second pressure plate 27.

[0037] Specifically, the heat sealing mechanism 30 includes a heat sealing element 31, a first heating component 32, and a heat sealing element driving structure 33. The first heating component 32 is used to heat the heat sealing element 31. The heat sealing element 31 can be a heat sealing seat, a heat sealing shell, etc. The heat sealing element 31 has a downwardly protruding hot-pressing flange. The trajectory shape of the hot-pressing flange is the same as the edge shape of the lithium battery electrode except for its tab. The shape and size of the hot-pressing flange are larger than the edge shape of the electrode, so as to achieve a matching cover of the lithium battery electrode. The heat sealing element driving structure 33 is used to drive the heat sealing element 31 along... Y-axis movement; In use, the hot-pressing flange is positioned directly above any operating platform 23; the first heating component 32 heats the heat-sealing component 31, thus the hot-pressing flange is heated and its temperature rises. In conjunction with the heat-sealing component driving structure 33, the heat-sealing component 31 moves downward along the Y-axis. Then, the hot-pressing flange adheres to the upper separator 60, and under the action of the heat-sealing component driving structure 33, it continues to press the lower separator downward. At this time, the upper separator 60 and the lower separator are bonded together along the edge of the lithium battery electrode in one go under the heat melting of the hot-pressing flange, saving bonding time.

[0038] Furthermore, the cutting mechanism 40 includes a cutter 41, a cutter drive structure 42, and a second heating assembly. The second heating assembly heats the cutter 41. The blade of the cutter 41 faces downwards, and in use, the blade of the cutter 41 is oriented towards the operating platform 23. The trajectory shape of the blade of the cutter 41 is the same as the edge shape of the adhesive part, and the size of the trajectory shape of the blade of the cutter 41 is greater than or equal to the size of the edge shape of the adhesive part. The cutter drive structure 42 drives the cutter 41 to move along the Y direction. In use, the second heating assembly heats the cutter 41, and the cutter drive structure 42 drives the cutter 41 to move towards the operating platform 23, and the blade of the cutter 41 continues to move downwards after touching the upper diaphragm 60. At this time, under the thermal cutting of the blade of the cutter 41, the upper diaphragm 60 and the lower diaphragm are cut off along the edge of the adhesive part in one go.

[0039] Both the first heating element 32 and the second heating element mentioned above can be existing heating wires, heating tubes, etc.

[0040] Furthermore, this high-efficiency lithium battery electrode bag making machine also includes a frame 70, a mounting plate 80, a mounting plate drive structure 90, and a traction roller assembly 100 and a pressing mechanism 110, both mounted on the mounting plate 80. The traction roller assembly 100 is used for the upper diaphragm 60 to be wound around it. The mounting plate 80 drive mechanism is used to drive the mounting plate 80 to move in the X direction, so as to pull the upper diaphragm 60 above or away from the operating platform 23 in conjunction with the traction roller assembly 100. The pressing mechanism 110 is used to push the upper diaphragm 60 located on the operating platform 23 towards the operating platform 23. The traction roller assembly 100, the pressing mechanism 110, the heat sealing mechanism 30, and the cutting mechanism 40 are arranged sequentially along the arrangement direction of the heat sealing station and the cutting station. The heat sealing mechanism 30 and the cutting mechanism 40 are both mounted on the mounting plate 80.

[0041] Based on the above structure, when using this high-efficiency lithium battery electrode bag making machine, the upper separator 60 is passed around the traction roller assembly 100 and then placed between the operating platform 23 and the first pressure plate 25, and pressed firmly onto the operating platform 23 by the first pressure plate 25. When it is necessary to place the lithium battery electrode onto the lower separator on the operating platform, the mounting plate drive structure 90 drives the mounting plate 80 to move... Figure 1 Moving in the direction indicated by the middle arrow A1, the traction roller pulls the upper diaphragm 60 away from the operating platform 23, that is, makes the upper diaphragm 60 away from the lower diaphragm. After the lithium battery electrode is placed, the mounting plate drive structure 90 drives the mounting plate 80 to move in the direction indicated by the middle arrow A1. Figure 1Moving in the direction indicated by the middle arrow A2, the traction roller assembly 100 pulls the upper diaphragm 60 above the operating platform 23. Then, the pressing mechanism 110 presses the upper diaphragm 60 downward, thus achieving the bonding of the upper diaphragm 60 and the lower diaphragm. After that, heat sealing and cutting operations can be performed. In this way, the first pressure plate 25 and the pressing mechanism 110 cooperate to press both sides of the upper diaphragm 60 onto the lower diaphragm respectively. The setting of the first pressure plate 25 can eliminate the need for additional components to press one side of the upper diaphragm 60, simplifying the structure.

[0042] Specifically, the pressing mechanism 110 includes a pressure roller 111, a support 112, and a pressure roller drive mechanism 113; the pressure roller 111 is pivotally connected to the support 112; the pressure roller drive mechanism 113 is used to drive the support 112 to move along the Y direction, and the pivot connection of the pressure roller 111 can reduce the friction on the upper diaphragm 60.

[0043] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
