DETAILED DESCRIPTION OF THE INVENTION

[0014] The technical content, structural features, objects, and effects to be achieved in this application are described in detail with reference to the accompanying figures. More specifically, the terms used in the embodiments of this application are used only to describe the specific embodiments, rather than to limit this application.

[0015] The present application will be described in more detail below with reference to the attached figures.

[0016] With reference to Figures 1 to 7, a device for cutting strips of material 100 according to one or more embodiments of the present application is used to cut strips of material 200 into electrode plates 300, comprising a bench 10, a cutting mechanism 20, a drive roller mechanism 30 and a cutting drive mechanism 40.

[0017] As shown in Figures 1 and 2, the bench 10 is used to support the strips of material 200; the drive roller mechanism 30 is mounted on the bench 10 and used to transport the strips of material 200 and comprises two pairs of drive roller assemblies 31 arranged separately; the cutting mechanism 20 is arranged between the two pairs of drive roller assemblies 31 and is used to cut the strips of material 200 one by one into electrode plates 300; the cutting drive mechanism 40 is mounted on the bench 10 and is used to mount the cutting mechanism 20;in which the cutting mechanism 20 allows the material strips 200 to be cut, without drive provided by the cutting drive mechanism 40, in a static state, or moves, under the drive of the cutting drive mechanism 40, in a direction of movement of the material strips 200, thus performing a cut on the material strips 200 in a moving state. ;

[0018] The bench 10 supporting the material strip 200 and the drive roller mechanism 30 driving the material strip 200 to move, the material strip cutting device 100 above allows the material strip 200 to be cut in a static state or in a moving state, the material strip 200, when it reaches a target position, slows down to a speed of 0 to be cut into electrode plates 300 by the cutting mechanism 20, or when the material strip 200 does not slow down, the cutting mechanism 20 can move under the drive of the cutting drive mechanism 40 to maintain static relative to the material strip 200 in order to cut the material strip 200, thus, the material strip 200 does not need to be put in a static state, which ensures the efficiency of the cutting and improves the production yield.

[0019] As shown in Figures 1 and 3, on the structural diagrams, the bench 10 according to the embodiments of the present application comprises a lower plate 12, two vertical plates 13 arranged at opposite ends of the lower plate 12 and a support plate 11 arranged at the top of the two vertical plates 13, thus the lower plate 12, the two vertical plates 13 and the support plate 11 surround a mounting space.

[0020] As shown in Figures 3 and 4, according to one embodiment of the present application, the cutting mechanism 20 comprises a first drive element 21, a drive wheel 22, a plurality of driven wheels 23, and a conveyor belt 24 and a cutting blade 25; the cutting blade 25 is mounted on the conveyor belt 24; the drive wheel 22 is connected to the first drive element 21, the plurality of driven wheels 23 are arranged separately on the cutting drive mechanism 40, the conveyor belt 24 is arranged to wrap around the drive wheel 22 and the plurality of driven wheels 23, and under the drive of the first drive element 21, the cutting blade 25 can move from one side to the other side of the material strip 200 in a direction of the width of the material strip 200, thus performing a cut on the material strip 200.Thus, because the cutting blade 25, when cutting the material strip 200, is always in motion under the drive of the conveyor belt 24, in order to cut the material strip 200 from one side to the other side of the material strip 200, a cutting blade 25 with a relatively small width can be provided, thus avoiding the cutting blade 25 occupying a large space, taking into account the relatively small reach width of the blade, a corresponding cutting blade 25 which has a width identical to that of the material strip 200 is provided, which reduces the maintenance cost for replacement in case of wear.

[0021] In particular, the drive wheel and the conveyor belt according to the present embodiment are in the form of a sprocket and chain, therefore it is sufficient to renew the lubricating oil for subsequent maintenance, thus facilitating maintenance.

[0022] Furthermore, in order to reduce the volume occupied by the entire material strip cutting device 100 and to make the configuration of the entire device more compact, the bench 10 has a support plate 11 to support the material strip 200, the conveyor belt 24 is arranged to wrap around the support plate 11, the first drive element 21 and the drive wheel 22 are arranged under the support plate 11, thus, by arranging the conveyor belt 24 to wrap around the support plate 11 and by arranging the first drive element 21 and the drive wheel 22 under the support plate 11, a configuration of the components of the entire device is compact and the volume occupied by the entire device is reduced.According to other embodiments, the drive wheel 22 and the driven wheel 23 can be arranged in a direction of the width of the material strip 200, the conveyor belt 24 is arranged above the support plate 11 and the first drive element 21 is arranged on one side of the support plate 11, which also achieves an effect of the circulation movement of the conveyor belt 24, i.e. the cutting blade 25 can also be driven to cut the material strip 200.

[0023] It will be understood that, given that the conveyor belt 24 has a certain extension length, in order to ensure cutting stability when the blade of cutting 25 is driven to cut the material strip 200, the cutting mechanism 20 further includes a pair of tensioning rollers 26, the pair of tensioning rollers 26 are arranged symmetrically on either side of the drive wheel 22 to tension the conveyor belt 24, therefore, by arranging the two tensioning rollers 26, the conveyor belt 24 can be tensioned, and the cutting blade 25 applies a stable cutting force on the material strip 200 when the cutting blade 25 is driven to cut the material strip 200, thus reducing the production of burrs.

[0024] In which, the present embodiment comprises four driven wheels 23, in which two driven wheels 23 are arranged on each side of the width direction of the support plate 11, one of the driven wheels 23 is located above the support plate 11, and the other driven wheel 23 is arranged below the support plate 11, which makes it possible to tension the conveyor belt 24, and allows the conveyor belt 24 to drive the cutting blade 25 to pass over and along the support plate 11.

[0025] Furthermore, since the cutting drive mechanism 40 can drive the cutting mechanism 20 to move in a direction along the length of the material strip 200 to cut the material strip 200, in order to ensure continuity of cutting, the cutting mechanism 20 comprises a plurality of cutting blades 25, and the plurality of cutting blades 25 are arranged at equal intervals on the conveyor belt 24, thus, once the cutting blades 25 are driven to cut the material strip 200 into electrode plates 300, the material strip 200 continues to move, under the drive of the drive roller assembly 31, towards the other drive roller assembly 31, in parallel, the conveyor belt 24 drives another cutting blade 25 to reach the side of the material strip 200, thus, the material strips 200 are cut in a cycle,This ensures continuity of the cutting process and improves production efficiency.

[0026] As shown in [Fig. 4], according to one embodiment of the present application, in order to facilitate the collection of debris produced during cutting, the cutting blade 25 generally extends towards the inside of a ring in the conveyor belt 24, which is ring-shaped. The support plate 11 is provided with a cutting groove 111, and the cutting blade 25, when cutting the strip of material 200, extends into the cutting groove 111. Thus, once the cutting blade 25 has cut the strip of material 200, the resulting debris enters the cutting groove 111 and is collected by the cutting groove 111 to prevent it from being dispersed throughout the environment. In other embodiments, the cutting blade 25 may also extend outwards from the ring, and the entire cutting process occurs under the support plate 11, a through hole is provided on the support plate 11, the through hole is arranged in the direction of the width of the support plate 11, and the cutting blade 25, when it cuts the strip of material 200, extends from the bottom of the through hole upwards, so that the strip of material 200 can also be cut through the movement of the cutting blade 25.

[0027] As shown in [Fig.3], when the cutting blade 25 cuts the strip of material 200, the cutting blade 25 rests against a side wall of the cutting groove 111 to be supported by the side wall of the cutting groove 111, which helps to reduce the deformation of the cutting blade 25.

[0028] Furthermore, in order to avoid an accumulation of debris in the cutting groove 111, which affects the continuous progression of the cutting, the side wall of the cutting groove 111 is provided with a first negative pressure suction orifice 112, as shown in [Fig.6], so that the debris can be sucked up by the first negative pressure suction orifice 112 under adsorption by a negative pressure mechanism, instead of being blocked in the cutting groove 111, thus ensuring the continuity of production.

[0029] In addition, in order to ensure that the strip of material 200 can be in a static state during cutting, the support plate 11 is provided with a plurality of second negative pressure suction orifices 113 to suction the strip of material 200 onto a surface of the support plate 12, which avoids any shaking during cutting, thus reducing the production of burrs and ensuring the quality of the cutting.

[0030] It will be understood that, in order to cut the strip of material 200 in static state, one direction of movement of the cutting blade 25 is just the direction of the width of the support plate 11, therefore, in this case, the direction of extension of the cutting groove 111 is just the direction of the width of the support plate 11, that is to say the direction of the width of the strip of material 200, as shown in [Fig.6] ; to cut the material strip 200 in motion, given that the cutting blade 25 performs on the one hand a linear movement in the direction of the cutting, and on the other hand a linear movement under the drive of the cutting drive mechanism 40 in the direction of the movement of the material strip 200, a movement path of the cutting blade 25 is a composite path of the cutting path and the linear movement, which is inclined with respect to the width direction of the support plate 11 and has an included angle with respect to the width direction of the support plate 11, as shown in [Fig.7]. .

[0031] As shown in Figures 3 and 4 of the structural diagrams, the cutting drive mechanism 40 according to the embodiments of the present application comprises a linear motor 41 and a mounting frame 42 disposed on the motor linear 41, and the mounting frame 42 is used to mount the cutting mechanism 20, in order to drive, under the drive of the linear motor 41, the cutting mechanism 20 to move in a direction of movement of the parallel material strips 200, in which the linear motor 41 comprises a linear stator 411 and a linear moving element 412, the linear stator 411 is mounted to the lower plate 12 and the linear moving element 412 is mounted to the mounting frame 42, thus driving the cutting mechanism 20 to perform a linear movement.

[0032] Furthermore, in order to ensure the stability of the linear motor 41 driving the cutting mechanism 20 to perform a linear movement, the strip cutting device 100 further includes a linear guide rail 50 and a slider 60 which are arranged to slide relative to each other, the linear guide rail 50 is mounted on the bench 10 and extends in the direction of the movement of the material strip 200, and the slider 60 is mounted on the cutting mechanism 20, so that when the linear motor 41 drives the cutting mechanism 20 to perform a linear movement, the slider 60 slides synchronously relative to the linear guide rail 50 to support the mounting frame 42 and also guide the movement of the cutting mechanism 20.

[0033] As shown in [Fig. 5], according to one embodiment of the present application, each pair of drive roller assemblies 31 comprises an upper roller 311, an upper drive motor 312, a lower roller 313 and a lower cylinder 314, the upper roller 311 and the lower roller 313 are arranged opposite each other, the upper drive motor 312 is used to drive the upper roller 311 to rotate, and the lower cylinder 314 is used to drive the lower roller 313 to approach or move away from the upper roller 311, thus, when the strip of material 200 has to be penetrated manually, or when a blockage has occurred, such an operation can be facilitated by the lower cylinder 314 driving the lower roller 313 to approach or move away from the upper roller 311.

[0034] In which, the strip cutting device 100 according to the present embodiment is used in the following manner, in order to facilitate the description of the movement process of the strip of material 200, two pairs of drive roller assemblies 31 are respectively defined as front drive roller assembly a and rear drive roller assembly b, see [Fig.2]

[0035] a. for cutting strips of material 200 in a static state:

[0036] (1) First, the strips of material 200 are successively driven towards the front by the front drive roller assembly has a lower low speed at 1.5 m / s, then pass through the cutting mechanism 20 and the rear drive roller assembly b;

[0037] (2) when the strips of material 200 successively arrive at a position where is the cutting mechanism 20, the front drive roller assembly causes the material strips 200 to slow down gradually, and when the speed of the material strips 200 decreases to 0, the cutting mechanism 20 cuts the material strips 200;

[0038] (3) once the strips of material 200 are cut into electrode plates 300, The rear drive roller assembly b drives an electrode plate 300 away at a speed twice the speed of the material strip movement 200 to complete the cutting of one electrode plate 300 and wait for the arrival of the next electrode plate 300.

[0039] a. to cut the material strips 200 in motion, in this case, the cutting drive mechanism 40 approaches the side where the front drive roller assembly a is located and waits:

[0040] (1) First, the strips of material 200 are successively driven towards the front by the front drive roller assembly a at a high speed greater than 1.5 m / s, then pass through the cutting mechanism 20 and the rear drive roller assembly b;

[0041] (2) once the 200 strips of material have entered the roller assembly rear drive b, the rear drive roller assembly b accelerates 1.01 to 1.05 times the speed of the front drive roller assembly to ensure the required tension for cutting the 200 material strips;

[0042] (3) at the moment when the strips of material 200 enter the roller assembly b and are driven, the linear motor 41 drives the cutting mechanism 20 to accelerate from an initial position, and once accelerated to the speed of the material strips 200, the cutting blade 25 driven by the pinion begins to cut the material strips 200 transversely, and in parallel, in the cutting process, the negative pressure mechanism is actuated to suck up the debris;

[0043] (4) once the cutting is complete, the rear drive roller assembly b accelerates and sends the electrode plate 300 to the next station, and in parallel, the linear motor 41 begins to slow down to return and waits for a start signal to cut the next electrode plate 300.

[0044] Thus, the strip cutting device 100 according to the embodiments of the present application makes it possible to selectively cut the strip of material in a static state, and also to cut the strip in a moving state, thus operating in different modes of use, which improves the practicality of the device cutting of 100 strips and also reduces the maintenance cost of the cutting blade by 51.

[0045] Although the content of this application has been described in combination with the embodiments considered to be the most practical and preferred, it should be understood that the content of this application is not limited to the disclosed embodiments, but is intended to cover various configurations realized without departing from the scope of the broadest interpretation of the annexed claims.
