Description

Technical Field

[0001] The present invention belongs to the technical field of plate cutting, and particularly relates to a plate dividing device with a guiding and feeding function. Background Art

[0002] Most of the plates produced in the green plate workshop are cut by mechanical hanging block positioning. During cutting, the plates are bent, and a stress angle is formed on the upper border of the plates. The angles of the two plates are both bent towards the axis direction of the lower anvil roller of the mold. This angle cannot be completely eliminated during the processes of plate collection, stacking, curing, and drying. In the assembly and manufacturing process, if the positive and negative plates are angled relative to each other, a stress point will cause puncture damage to the separator, resulting in a short circuit and scrapping of the entire battery.

[0003] Currently, to reduce the short - circuit risk between plates, through direction matching, such angles are made to be "bent in the same direction" instead of "facing each other", reducing the angle, which is commonly known as the "north - south plate" matching method. The direct consequence of this production organization method is that the plate feeding in the plate direction should avoid mis - feeding, thus increasing the difficulty of production organization. Since one type of plate may be proportionally combined with different types of plates, a large number of plates cannot be fully used in the end, resulting in a large stock of plates bent in the same direction. Therefore, a large number of "same - side - leaning" plates in the plate warehouse cannot be used, occupying inventory and wasting costs.

[0004] Therefore, how to provide a plate dividing device with a guiding and feeding function is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a plate dividing device with a guiding and feeding function, which can avoid plate bending during cutting, reduce the generation of stress angles, and does not require special inventory organization, thus reducing inventory costs.

[0006] To achieve the above - mentioned purpose, the present invention adopts the following technical solution: A plate dividing device with a guiding and feeding function, which includes:

[0007] A plate dividing frame, on which a feeding roller and a plate dividing roller are rotatably connected. The feeding roller and the plate dividing roller cooperate up and down to cut a plate chain.

[0008] A guiding frame, which is fixed on one side of the plate dividing frame corresponding to the upstream feeding. A loading roller is rotatably connected to the guiding frame. A positioning block is arranged in the middle of the outer side wall of the loading roller. The positioning block cooperates with the tab on the plate chain to hang and send the plate chain forward.

[0009] A material rail, which is fixed on the guiding frame and is located between the feeding roller and the loading roller. The loading surface of the material rail is on the horizontal cutting plane at the top of the feeding roller.

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

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

[0012] The beneficial effects of the present invention are as follows: before the plate chain is processed for plate separation, it is pre-pressed by the lifting and clamping rollers and the material rails to avoid bending after plate separation; the servo synchronous transmission mechanism can ensure the consistency of feeding and feeding, and avoid stretching and bending caused by asynchronous transmission of the plate chain; consistent plates do not need to be organized in batches for storage, which is convenient for later production and busbar assembly processes, and reduces inventory costs.

[0013] Preferably, a plurality of hanging blocks for hanging the electrode chain are fixed in the middle of the feed roller, the hanging block adapter card is located in the gap between adjacent electrode ears of the electrode chain, and a plurality of cutting grooves are provided on the outer wall of the feed roller corresponding to the direction of the roller axis, and the cutting grooves are used to avoid the cutting knife on the plate separation roller.

[0014] The resulting technical effect is: before the electrode plates are split, they will be transported in the form of electrode plate chains. There will be gaps between the pole ears in the electrode plate chain. At this time, the hanging blocks on the feed rollers are used to embed between adjacent pole ears and hang the electrode chain forward. The hanging blocks also have the function of positioning the electrode chain to ensure the position of the electrode chain before splitting. In order to ensure the effective splitting of the electrode plates and avoid continuous adhesion of the electrode plates after splitting, the provided cutting grooves can increase the depth of the cutting knife.

[0015] Preferably, the plate splitting roller and the feed roller have an upper and lower spacing distance, and a cutter is detachably connected to the outer wall of the plate splitting roller. The plate splitting roller is symmetrically provided with a first working area and a second working area corresponding to the roller axis direction, and the cutter in the first working area and the cutter in the second working area are staggered, and a pole ear dividing blade is provided on the plate splitting roller and close to the first working area and the second working area.

[0016] The resulting technical effect is that there is an upper and lower spacing distance between the plate dividing roller and the feed roller, which ensures that the plate chain is flat before being divided into multiple plates and will not be deformed due to the squeezing of the plate dividing roller and the feed roller. By using the first working area and the second working area to staggeredly divide the plate chain, the stress deformation problem caused by simultaneous cutting on both sides can be avoided. It can be understood that the plate chain is staggered and continuously divided into multiple plates left and right under the action of the first working area and the second working area.

[0017] Preferably, a protrusion is arranged on the outer side wall of the plate separation roller and on the side corresponding to the first working area and the second working area, and the protrusion cooperates with the feeding roller to squeeze the upper frame of the plate, and the protrusion has a knife groove for avoiding the cutting knife.

[0018] The resulting technical effect is that the protrusion can reversely extrude the upper frame of the electrode plate, thereby changing the stress angle on the electrode plate.

[0019] Preferably, both ends of the material rail are provided with connecting sections connecting the feeding roller and the loading roller. The bottom side of the connecting section is provided with an arc surface, and the horizontal cutting plane at the top of the loading roller is 1 mm to 3 mm higher than the material-carrying surface of the material rail.

[0020] The resulting technical effect is that the material rail is used to carry the flat electrode plate chain forward for delivery. The connecting section can ensure the sequential conveying process of the electrode plate chain as much as possible, avoiding the deformation problem of the electrode plate chain caused by its own gravity due to the interval. The electrode plate chain sent by the loading roller has a certain degree of curvature. At this time, the material rail and the lifting pressing roller are used in cooperation to reversely eliminate the stress deformation, so as to ensure the flatness of the electrode plate chain before plate splitting.

[0021] Preferably, the lifting pressing roller includes a lifting frame and a reverse pressing roller. The lifting frame is connected to the guiding frame of the material. A cylinder for driving its lifting is connected to the lifting frame. The reverse pressing roller is rotatably connected to the lifting frame, and the reverse pressing roller rotates on the discharging side of the loading roller.

[0022] The resulting technical effect is that the reverse pressing roller is used to provide a reverse acting force. When used in cooperation with the material rail, it can not only flatten the bent shape of the electrode plate chain, but also apply force to the upper frame of the electrode plate, so that the stress angle generated during the previous process of cutting (forming the tab) between the plates disappears.

[0023] Preferably, a ring groove for avoiding the positioning block is provided in the middle of the reverse pressing roller.

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

[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 plate-splitting frame. The output shaft of the servo motor is drivingly connected to the input end of the reducer. The output end of the reducer is respectively drivingly connected to the feeding roller, the plate-splitting roller and the loading roller through the transmission wheel set. The outer diameters 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 synchronism of the feeding roller and the loading roller, ensure the synchronous conveying process of loading and cutting, and avoid the stretching deformation of the electrode plate chain during the conveying process.

[0027] Preferably, a protective grille is connected to the outside of the guiding frame of the material.

[0028] The resulting technical effect is that the protective grille can improve the safety of workers' operations and avoid accidents. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Refer to the attached drawings of the present invention Figures 1 to 4 , a plate-splitting device with a guiding and feeding function according to an embodiment of the present invention includes:

[0038] A plate-splitting frame 1, on which a feeding roller 2 and a plate-splitting roller 3 are rotatably connected. The feeding roller 2 and the plate-splitting roller 3 cooperate up and down to split the plate chain 4;

[0039] The material guiding frame 6 is fixed to one side of the board splitting frame 1 corresponding to the upstream feeding. A feeding roller 7 is rotatably connected to the material guiding frame 6. A positioning block 8 is provided in the middle of the outer side wall of the feeding roller 7. The positioning block 8 cooperates with the tab 5 on the plate chain 4 and hangs to send the plate chain 4 forward.

[0040] The material rail 9 is fixed to the material guiding frame 6 and is located between the material conveying roller 2 and the feeding roller 7. The loading surface of the material rail 9 is on the top horizontal section of the material conveying roller 2.

[0041] The lifting and pressing roller 10 is installed on the material guiding frame 6 and is located above the material rail 9. The lifting and pressing roller 10 cooperates with the material rail 9 to flatten the plate chain 4.

[0042] The servo synchronous transmission mechanism 11 is installed on the board splitting frame 1. The servo synchronous transmission mechanism 11 is respectively in transmission connection with the material conveying roller 2, the board splitting roller 3, and the feeding roller 7.

[0043] It should be noted that the plates exist in the form of a chain during slitting. In the early stage, the plates are slit between the boards to highlight the positions of the tabs. The gaps between the tabs are used for the positioning and hanging of the material conveying roller and the feeding roller.

[0044] In some other embodiments, a plurality of hanging blocks 201 for hanging the plate chain 4 are fixed in the middle of the material conveying roller 2. There are a plurality of them, which are arranged at intervals around the outer side wall of the middle part of the material conveying pipe. The hanging blocks 201 are adaptively clamped in the gaps between adjacent tabs of the plate chain. A plurality of cutter grooves are provided on the outer side wall of the material conveying roller 2 corresponding to the roller axis direction. The cutter grooves are used to avoid the cutters 301 on the board splitting roller. The cutter grooves can ensure the depth of the cutters and avoid the problem of adhesion of the plates after splitting.

[0045] In some other specific embodiments, there is a vertical interval distance between the board splitting roller 3 and the material conveying roller 2. A cutter 301 is detachably connected to the outer side wall of the board splitting roller 3. The board splitting roller 3 is symmetrically provided with a first working area 302 and a second working area 303 in the corresponding roller axis direction. The cutters in the first working area 302 and the cutters in the second working area 303 are arranged in a staggered manner. Ear splitting edges 304 are provided inside the board splitting roller 3 near the first working area and the second working area. In this way, the staggered splitting process of the plates can be realized. In specific implementation, in order to improve the flatness of the plates, a protrusion is provided around the position of the board splitting roller close to the upper border of the plate. The protrusion cooperates with the material conveying roller to squeeze the upper border of the plate, which can further eliminate the stress angle during the slitting between the plates, thereby improving the flatness of the plates. The ear splitting edge 304 is located on one side of the protrusion and extends out of the protrusion.

[0046] In some other embodiments, both ends of the material rail 9 are provided with connection sections connecting the feeding roller and the loading roller 7. The bottom side of the connection section is provided with an arc surface. The horizontal cutting plane at the top of the loading roller 7 is 1 mm to 3 mm higher than the material loading surface of the material rail 9. When the plate chain enters the material rail, there is a reverse bending process, so as to ensure the flatness of the part of the plate chain entering the material rail.

[0047] In some other specific embodiments, the lifting and pressing roller 10 includes a lifting frame 101 and a reverse pressing roller 102. The lifting frame 101 is connected to the material guiding frame 6. A cylinder 103 for driving its lifting is connected to the lifting frame 101. The reverse pressing roller 102 is rotatably connected to the lifting frame 101. The reverse pressing roller 102 rotates on the discharging side of the loading roller 7. The position of the reverse pressing roller is reasonably adjusted according to the requirements of plate splitting, so as to ensure that the plate chain is flat before entering the plate splitting process.

[0048] In some other embodiments, a ring groove for avoiding the positioning block 8 is provided in the middle of the reverse pressing roller 102.

[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 plate splitting frame 1. The output shaft of the servo motor 1101 is drivingly connected to the input end of the reducer 1102. The output end of the reducer 1102 is respectively drivingly connected to the feeding roller 2, the plate splitting roller 3 and the loading roller 7 through the transmission wheel set 1103. The outer diameters of the feeding roller 2 and the loading roller 7 are the same and they rotate synchronously. Thus, the consistency during feeding and plate splitting and conveying is ensured. The stretching deformation during the transmission of the plate chain is avoided, and the mechanical stepping is replaced by servo stepping, saving the manufacturing cost.

[0050] In some other embodiments, a protective grille 12 is connected to the outside of the material guiding frame 6, thereby improving the safety of the staff.
