Description

Technical Field

[0001] This utility model belongs to the field of electrode plate slitting technology, specifically relating to a slitting device with a guiding feeding function. Background Technology

[0002] Most of the electrode plates produced in the raw plate workshop are mechanically cut using a hanging block positioning method. This causes the electrode plates to bend during cutting, creating a stress angle on the upper edge of the plate. The angle between the two plates bends towards the axis of the anvil roller under the mold. This angle cannot be completely eliminated during the plate collection, stacking, and curing / drying processes. During assembly, if the positive and negative electrode plates are at opposite angles, this creates a point of force that can puncture the separator, causing a short circuit and rendering the entire battery unusable.

[0003] To reduce the risk of short circuits between electrodes, existing methods use directional matching to make the included angles no longer "facing each other" but "bending in the same direction," thus reducing the included angle. This is commonly known as the "north-south plate" matching method. However, the direct consequence of this production organization method is that electrode direction must be avoided during plate delivery, increasing the difficulty of production organization. Because one type of electrode may be combined with different types of electrodes, a large number of electrodes cannot be fully used, resulting in a large inventory of bent electrodes. Consequently, a large number of "straight-sided" plates remain unused in the electrode warehouse, occupying inventory and wasting costs.

[0004] Therefore, how to provide a plate separating device with guiding and feeding function is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a plate separating device with a guiding feeding function, which avoids plate bending, reduces stress angle generation, eliminates the need for special inventory organization, and reduces inventory costs.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a plate-separating device with guiding and feeding function, comprising:

[0007] A slitting frame is provided, on which a feeding roller and a slitting roller are rotatably connected. The feeding roller and the slitting roller cooperate with each other to cut the electrode chain.

[0008] A feeding frame is fixed on the side of the slitting machine frame corresponding to the upstream feed. A feeding roller is rotatably connected to the feeding frame. A positioning block is provided in the middle of the outer side wall of the feeding roller. The positioning block cooperates with the electrode lug on the electrode chain and hooks the electrode chain to move forward.

[0009] The material rail is fixed on the guide frame and located between the feeding roller and the loading roller, and the material loading surface of the material rail is located on the top horizontal sectional surface of the feeding roller;

[0010] A lifting and pressing roller is installed on the guide frame and located above the material rail. The lifting and pressing roller cooperates with the material rail to flatten the electrode plate chain.

[0011] A servo synchronous transmission mechanism is installed on the slitting machine frame and is connected to the feeding roller, slitting roller and loading roller respectively.

[0012] The beneficial effects of this invention are: before the plate separation process, the plates are pre-pressed flat by the lifting and pressing rollers and the material rail, preventing bending after separation; the servo synchronous transmission mechanism ensures the consistency of feeding and conveying, avoiding stretching and bending caused by asynchronous transmission of the plate chain; and consistent plates do not require batch storage, facilitating subsequent production and busbar assembly processes, thus reducing inventory costs.

[0013] Preferably, the middle part of the feeding roller is fixed with a plurality of hanging blocks for hanging the electrode chain, the hanging block adapter is located in the gap between adjacent electrode ears of the electrode chain, and the outer side wall of the feeding roller is provided with a plurality of cutting grooves corresponding to the roller axis direction, the cutting grooves being used to avoid the cutting blades on the separating roller.

[0014] The resulting technical effect is that the plates are transported in the form of a plate chain before the plates are split. There are gaps between the tabs in the plate chain. At this time, the hanging blocks on the feed rollers are used to embed between the adjacent tabs and to hang the plate chain forward. The hanging blocks also have the function of positioning the plate chain to ensure the position of the plate chain before splitting. In order to ensure effective splitting of the plates and avoid the plates sticking together after splitting, the cutting groove can increase the cutting depth.

[0015] Preferably, the separating roller and the feeding roller have an upper and lower gap distance, and a cutter is detachably connected to the outer wall of the separating roller. The separating roller is symmetrically provided with a first working area and a second working area in the direction of the roller axis. The cutter in the first working area and the cutter in the second working area are staggered. The separating roller is provided with a tab dividing blade on the inside of the separating roller and close to the first working area and the second working area.

[0016] The resulting technical effect is that the separating roller and the conveying roller have an upper and lower gap, which ensures that the electrode chain is flat before being divided into multiple electrode plates and will not be deformed due to the squeezing of the separating roller and the conveying roller. The electrode chain is divided by the staggered division of the first working area and the second working area, which can avoid the stress deformation problem caused by cutting on both sides at the same time. It can be understood that the electrode chain is divided into several electrode plates by staggered left and right under the action of the first working area and the second working area.

[0017] Preferably, the outer side wall of the separating roller is provided with protrusions on the side that is close to the first working area and the second working area. The protrusions cooperate with the feeding roller to squeeze the upper frame of the electrode plate. The protrusions have through grooves for the avoidance cutter.

[0018] The resulting technical effect is that the protrusion can press against the upper edge of the electrode plate in the opposite direction, thereby changing the stress angle on the electrode plate.

[0019] Preferably, the two ends of the material rail are provided with connecting sections for connecting the feeding roller and the loading roller, the bottom side of the connecting section is provided with an arc-shaped surface, and the top horizontal cross-section of the loading roller is 1mm to 3mm higher than the material loading surface of the material rail.

[0020] The resulting technical effect is that the material rail is used to carry the flat electrode chain forward, the connecting section can ensure the sequential conveying process of the electrode chain as much as possible, and avoid the deformation of the electrode chain due to its own weight caused by the interval. The electrode chain delivered by the feeding roller has a certain degree of curvature. At this time, the material rail and the lifting and pressing roller are used to eliminate stress deformation in the opposite direction, thereby ensuring the flatness of the electrode chain before separation.

[0021] Preferably, the lifting and pressing roller includes a lifting frame and a reverse pressing roller. The lifting frame is connected to the material guide frame and a cylinder for driving its lifting and lowering is connected to the lifting frame. The reverse pressing roller is rotatably connected to the lifting frame and is rotatably located on the discharge side of the feeding roller.

[0022] The resulting technical effect is that the reverse clamping roller is used to provide a reverse force, which, when used in conjunction with the material rail, can flatten the curved shape of the electrode chain and also apply force to the upper edge of the electrode plate, thus eliminating the stress angle generated during the cutting process between the plates (forming the electrode ears).

[0023] Preferably, the reverse pressing roller has an annular groove for a positioning block in the middle.

[0024] The resulting technical effect is that, since the reverse pressing roller is close to the feeding roller, it will inevitably affect the use of the feeding roller positioning block. The set annular groove can avoid the positioning block and ensure the smooth progress of the feeding operation.

[0025] Preferably, the servo synchronous transmission mechanism includes a servo motor, a reducer, and a transmission wheel set. The servo motor and the reducer are fixed on the slitting machine frame. The output shaft of the servo motor is connected to the input end of the reducer. The output end of the reducer is connected to the feeding roller, the slitting roller, and the loading roller respectively through the transmission wheel set. The outer diameter of the feeding roller and the loading roller are the same and they rotate synchronously.

[0026] The resulting technical effect is that the servo motor can better ensure the synchronization of the feeding roller and the loading roller, ensuring the synchronous conveying process of feeding and cutting, and avoiding the stretching and deformation of the plate chain during the conveying process.

[0027] Preferably, a protective grille is connected to the outer side of the feeder frame.

[0028] The resulting technical effect is that protective grilles can improve worker safety and prevent accidents. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] See appendix to this utility model Figures 1 to 4According to an embodiment of the present invention, a separating device with a guiding and feeding function includes:

[0042] Servo synchronous transmission mechanism 11 is installed on the slitting machine frame 1 and is connected to the conveying roller 2, the slitting roller 3, and the feeding roller 7 respectively.

[0043] It should be noted that the electrode plates are in a chain-like form during the cutting process. The plates are cut in the early stage to make the electrode tabs stand out. The gaps between the electrode tabs are used for positioning and feeding of the feed rollers and loading rollers.

[0044] In other embodiments, a plurality of hanging blocks 201 for hanging the electrode chain 4 are fixed in the middle of the feeding roller 2. There are multiple hanging blocks 201, which are spaced in a ring on the outer side wall of the middle part of the feeding pipe. The hanging blocks 201 are fitted into the gaps between adjacent electrode ears of the electrode chain. A plurality of cutting grooves are provided on the outer side wall of the feeding roller 2 in the direction corresponding to the roller shaft. The cutting grooves are used to avoid the cutting blades 301 on the separating roller. The cutting grooves can ensure the cutting depth and avoid the problem of electrode adhesion after separation.

[0045] In some other specific embodiments, the separating roller 3 and the feeding roller 2 are spaced vertically apart. A cutter 301 is detachably connected to the outer wall of the separating roller 3. The separating roller 3 is symmetrically provided with a first working area 302 and a second working area 303 in the direction of the roller axis. The cutters in the first working area 302 and the cutters in the second working area 303 are staggered. The separating roller 3 is provided with a tab dividing blade 304 on the inside of both the first and second working areas. This enables the staggered division of the electrode plates. In specific implementation, in order to improve the flatness of the electrode plates, a protrusion is provided around the upper edge of the electrode plate near the separating roller. The protrusion cooperates with the feeding roller to squeeze the upper edge of the electrode plate. This can further eliminate the stress angle during the cutting process between the electrode plates, thereby improving the flatness of the electrode plates.

The lifting frame 101 is connected to the guide frame 6, and a cylinder 103 is connected to the lifting frame 101 to drive its lifting and lowering. The reverse pressing roller 102 is rotatably connected to the lifting frame 101 and is rotatably located on the discharge side of the feeding roller 7. The position of the reverse pressing roller is reasonably adjusted according to the plate separation requirements to ensure that the electrode chain is flat before entering the electrode plate separation process.

[0048] In other embodiments, the reverse pressing roller 102 is provided with an annular groove for the avoidance positioning block 8 in the middle.

[0049] In some other embodiments, the servo synchronous transmission mechanism 11 includes a servo motor 1101, a reducer 1102, and a transmission wheel set 1103. The servo motor 1101 and the reducer 1102 are fixed on the slitting frame 1. The output shaft of the servo motor 1101 is connected to the input end of the reducer 1102. The output end of the reducer 1102 is connected to the feeding roller 2, the slitting roller 3, and the loading roller 7 respectively through the transmission wheel set 1103. The feeding roller 2 and the loading roller 7 have the same outer diameter and rotate synchronously. This ensures consistency during feeding and conveying slitting. It avoids tensile deformation during the plate chain transmission process, allowing servo stepping to replace mechanical stepping, thus saving manufacturing costs.

[0050] In other embodiments, a protective grille 12 is connected to the outside of the feeder frame 6 to improve the safety of workers.
