Although various aspects of the embodiments are illustrated in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
In addition, the technical features described below in the different embodiments of the present utility model may be combined with each other as long as they do not collide with each other.
In the related art, the pole piece behind the cutting die usually adopts half absorption of belt negative pressure to convey, and when half absorption pole piece, because can surpass belt partly at belt width direction pole piece both ends, and the gap department at belt edge has the adsorption affinity equally, can lead to the pole piece to produce the pole piece mar because of the adsorption affinity is too big. In addition, the pole piece at the negative electrode preset position is also in negative pressure semi-adsorption transmission, and because the edge suction force is large, the problem of the scratch of the negative electrode preset position pole piece is frequent, so that the pole lug is deformed or torn, and further, the risk of abnormal positioning caused by inaccurate photographing and acquisition of a CCD (charge coupled device) camera at the negative electrode preset position is caused.

The technical solution of the present embodiment is described in detail below with reference to the accompanying drawings, and the following embodiments and implementations may be combined with each other without conflict.
In an exemplary embodiment of the present utility model, as shown in fig. 1-2, fig. 1 is a schematic diagram illustrating a conveying device for a pole piece according to an exemplary embodiment; fig. 2 is a block diagram of the negative pressure chamber and the negative pressure breaking flow path of the conveying device in fig. 1. The conveying device comprises: conveyor 20 and drive mechanism 40, cabin base plate 10.
The conveyor belt 20 and the driving mechanism 40 are provided with adsorption holes, wherein the adsorption holes are formed in the middle part A in the width direction of the conveyor belt 20, and the adsorption holes are uniformly distributed along the conveying direction of the conveyor belt 20.
The cabin base plate 10 is arranged in an extending manner along the conveying direction of the conveying belt 20, and the cabin base plate 10 is arranged on one side of the conveying section of the conveying belt 20 along the direction perpendicular to the conveying plane of the conveying belt 20. The deck base plate 10 has a first groove area corresponding to the middle portion a in the width direction of the conveyor belt 20 in the conveying direction and a second groove area corresponding to both side edge portions in the width direction of the conveyor belt 20 in the conveying direction on the deck surface facing the conveying section. When the conveying device adopts the inverted conveying mode, the cabin substrate 10 is disposed on the upper side of the conveying section (corresponding to the section of the conveying belt for adsorbing the conveying pole piece) of the conveying belt 20 along the conveying direction; when the conveying device adopts the normal conveying mode, the cabin substrate 10 is disposed at the lower side of the conveying section of the conveyor 20 (the section corresponding to the section of the conveyor that adsorbs the conveying pole piece) along the conveying direction.
The middle part A in the width direction of the conveyor belt 20 is matched with the first groove area to form a negative pressure cavity B so as to adsorb the pole piece 30 through the adsorption hole in the process of conveying the pole piece 30; the both side edge portions in the width direction of the conveyor belt 20 are fitted with the second groove regions to form a negative pressure breaking flow path C to balance the upper and lower side pressure differences of the both side edge portions of the conveyor belt 20 during the transfer of the pole pieces 30.
In the present exemplary embodiment, pole piece 30 is disposed laterally across conveyor belt 20 as pole piece 30 is transported on conveyor belt 20. Since the width of the cabin substrate 10 is greater than the width of the conveyor belt 20, the first slot area and the second slot area of the cabin substrate 10 are both located at the lower side of the conveyor belt 20, wherein the first slot area of the cabin substrate 10 corresponds to the middle of the pole piece, and the second slot area of the cabin substrate 10 is close to both ends of the pole piece (here, "close to" is relative to the first slot area, the second slot area does not correspond to both ends of the pole piece, and both ends of the pole piece fall on both sides of the width direction of the cabin substrate 10 beyond the edge of the conveyor belt 20). In order to prevent the pole pieces 30 from being adsorbed by the gap formed between the both sides of the conveyor belt 20 and the cabin base plate 10, a negative pressure breaking flow path C is designed to balance the pressure difference between the upper and lower sides of the both side portions of the conveyor belt 20. Specifically, by engaging the conveyor belt 20 with the cabin base plate 10 of the conveyor, the negative pressure chamber B is formed near the intermediate portion a in the belt width direction of the conveyor to suction-convey the pole pieces 30, and the negative pressure breaking flow passages C are formed near both side edge portions in the belt width direction of the conveyor 20. When the pole piece 30 is conveyed by the conveying device, gas is not sucked in through a gap between the edge part of the conveyor belt 20 and the cabin base plate 10, but is sucked in through the negative pressure breaking flow channel C, so that the edge of the conveyor belt 20 does not adsorb the pole piece 30, and the scratch of the pole piece 30 is not generated.
In some exemplary embodiments, as shown in fig. 1-3, fig. 3 is a schematic view of a nacelle substrate shown according to an exemplary embodiment. In the present exemplary embodiment, in order to prevent the pole piece 30 from being deviated in view of ensuring stability during the transfer process, the conveying device adopts a structure in which a negative pressure groove 101 is formed on the plate surface of the cabin base plate 10 corresponding to the first groove area. Wherein, negative pressure groove 101 cooperates with the downside of conveyer belt 20 to form negative pressure chamber B, and negative pressure groove 101 communicates to the negative pressure device through negative pressure through-hole 103.
Based on the negative pressure through hole 103 formed on the cabin substrate 10, the negative pressure groove 101 is communicated with the negative pressure device, and in the process of conveying the pole piece 30, the conveying belt 20 can be subjected to suction force generated in the first groove area, so that the conveying belt is attached to the board surface of the cabin substrate 10, and a negative pressure cavity B is formed in the first groove area. Because the adsorption holes are formed in the conveying belt 20, the pole pieces 30 can be adsorbed, and the stability of the pole pieces 30 in the conveying process of the pole pieces 30 is maintained. The pressure in the negative pressure chamber B may be adjusted according to actual needs, so as to meet the requirement that the pole piece 30 will not slide when being conveyed by the conveyor belt 20.
Because the broken negative pressure flow channels C are formed at the edge parts of the two sides of the conveyor belt 20, the edge of the conveyor belt 20 can be prevented from being influenced by the negative pressure cavity B, thereby preventing the pole piece 30 from being scratched at the edge of the conveyor belt 20 and further ensuring the safety of the pole piece 30.
In some exemplary embodiments, as shown in fig. 1 to 3, since the suction holes are provided on the conveyor belt 20, the suction holes form a movement path in a predetermined direction along with the movement of the conveyor belt 20. In order to ensure the reliability of the adsorption pole piece 30, the opening direction of the negative pressure tank 101 needs to be optimized to avoid the situation of interrupting adsorption. Illustratively, the negative pressure groove 101 is formed on the cabin substrate along the conveying direction (i.e., a groove parallel to the conveyor belt is formed at the middle portion of the cabin substrate), and the negative pressure groove 101 corresponds to the moving path of the suction hole, so that the suction hole can suck the pole piece 30 in real time.
In some exemplary embodiments, as shown in fig. 1-3, considering that after the negative pressure is formed in the negative pressure cavity B, gas leaks from the gap between the conveyor belt 20 and the cabin substrate 10, in order to reduce the suction effect of the negative pressure cavity B on the two side edges of the conveyor belt 20, the structure of the cabin substrate 10 in the conveying device is further optimized. In the present exemplary embodiment, a dividing strip 105 is formed between the first groove section and the second groove section in the conveying direction, wherein the dividing strip 105 serves to divide the negative pressure chamber B and the negative pressure breaking flow path C.
The dividing strip 105 may be based on an intermediate division formed between the first and second groove regions after the grooving process, or may be an elongated partition interposed between the first and second groove regions. In addition, the additional function of the separation strip 105 is to cooperate with the negative pressure device as much as possible to maintain the negative pressure environment in the negative pressure cavity B; another aspect is to reduce the absorption of the edge portion of the conveyor belt 20, thereby avoiding or reducing the scratch wear of the pole pieces 30 at the edges of the conveyor belt 20.
In some exemplary embodiments, as shown in fig. 1-3, the board surface of the cabin base plate 10 corresponding to the second groove area is provided with an air vent groove 102, where the air vent groove 102 cooperates with the lower side surface of the conveyor belt 20 to form a negative pressure breaking flow channel C, and the negative pressure breaking flow channel C is communicated with the inside and the outside.
To ensure that the conveyor belt 20 can achieve the negative pressure effect along the line, the ventilation grooves 102 are illustratively formed in the cabin base plate along the conveying direction (i.e., grooves parallel to the conveyor belt are formed in both side edge portions of the cabin base plate). It should be noted that the ventilation slot 102 may be a plurality of air slots formed along the conveying direction of the conveyor belt 20, or a plurality of air slots formed along the first preset direction and arranged along the conveying direction of the conveyor belt 20. The first preset direction is any horizontal direction different from the conveying direction of the conveyor belt 20.
In this embodiment, the conveying device adopts a mode of forming a groove type air guide under the edge of the conveyor belt 20, and the air source of the air inlet of the negative pressure cavity B is mainly air guided by the air channel 102 from the outside because the separation strip 105 is not tightly sealed. Specifically, when the gap between the edge portion of the conveyor belt 20 and the partition strips 105 on the cabin base plate 10 leaks air, a small negative pressure is caused at the air guide groove; because the inside and outside of the negative pressure breaking flow channel C are communicated, air is led in to decompress, so that the negative pressure in the air guide groove is close to 0, and the corresponding negative pressure at the edge of the belt is also in a state close to 0. At this time, the edge of the pole piece 30 is not scratched by suction in a negative pressure state close to 0.
On the basis, the power of the negative pressure device can be further increased, so that the adsorption force to the pole piece 30 is increased, the pole piece 30 is ensured not to be scratched at the edge of the conveyor belt 20 under the condition of firmly adsorbing the pole piece 30, and the problem of unstable adsorption of the pole piece 30 is effectively solved. The conveying device can reduce the rejection rate of the slice manufacturing section pole piece 30 to be close to 0 from about 0.4% after the cutting die is reversely hung. In addition, after the conveying device is used, the pole piece 30 is not absorbed and sunken by the negative pressure at the edge of the conveying belt 20, so that the problem of misjudgment of the size detection of the pole piece 30 caused by the absorption at the edge of the conveying belt 20 can be solved.
In some exemplary embodiments, as shown in fig. 1-4, fig. 4 is a schematic diagram of a delivery device of another pole piece, shown according to an exemplary embodiment. In this embodiment, to achieve the internal and external communication of the negative pressure breaking flow channel C, a groove may be formed in the cabin base plate 10 and/or the conveyor belt 20.
Illustratively, as shown in fig. 3, at least one groove end of the vent groove 102 extends to a plate end of the cabin base plate 10 in the conveying direction to communicate the inside and outside of the negative pressure breaking flow path C during conveying of the pole piece 30. Preferably, both ends of the ventilation groove 102 extend to the plate end of the corresponding cabin base plate 10, i.e., a ventilation groove is formed on the plate surface of the cabin base plate 10.
It should be noted that, in the case of adopting the mode of extending one slot end of the ventilation slot 102 to the plate end of the cabin substrate 10 in the conveying direction, the extending length of the ventilation slot 102 can be enough to adapt the movement path of the pole piece 30 on the conveying belt 20, that is, in the process of conveying the pole piece 30, the negative pressure breaking effect can be guaranteed to the edge portions of the conveying belt 20 corresponding to the two ends of the pole piece 30.
In another alternative, as shown in fig. 3, the bottom of the ventilation slot 102 is provided with a first through hole penetrating the body of the cabin base plate 10, so as to communicate the inside and outside of the negative pressure breaking flow channel C during the process of transferring the pole piece 30. At this time, the extending length of the ventilation slot 102 can be enough to adapt to the moving path of the pole piece 30 on the conveyor belt 20.
In this way, in order to solve the problem of sheet-making pole piece 30 skew, based on set up the first through-hole at the tank bottom of ventilation slot 102, can increase the negative pressure in the negative pressure chamber B according to actual need, effectively prevent to cause the condition that the corresponding belt edge department of pole piece 30 appears the mar in pole piece 30 conveying process.
Illustratively, the first through hole may be a square hole, a circular hole, or the like. Based on the fact that the square holes or the round holes are formed in the ventilation grooves 102 for air guiding, negative pressure breaking treatment is carried out on the edge portion of the conveyor belt 20, and after the negative pressure in the negative pressure cavity B is regulated according to actual needs, suction effect does not exist on the edge of the conveyor belt 20.
In another alternative, as shown in fig. 5 to 6, the edge portion of the conveyor belt 20 corresponding to the second groove region is provided with a second through hole, wherein the movement path of the second through hole corresponds to the ventilation groove 102 to communicate the inside and outside of the negative pressure breaking flow path C during the transfer of the pole piece 30. At this time, the extending length of the ventilation slot 102 can be enough to adapt to the moving path of the pole piece 30 on the conveyor belt 20.
In this way, the second through hole on the conveyor belt 20 is communicated with the external atmospheric pressure, when the pole piece 30 is adsorbed by the adsorption hole, the second through hole corresponding to the pole piece 30 is blocked, at this time, the external air led in by the other second through holes which are not blocked by the pole piece 30 at the edge part of the conveyor belt 20 can break the negative pressure, and the function that the edge part of the conveyor belt 20 adsorbs the pole piece 30 without negative pressure can be realized.
The three ways of realizing the internal and external communication of the negative pressure breaking flow channel C may be used independently or in combination. Such as by extending the both ends of the ventilation slot 102 to the both ends (the corresponding plate ends in the conveying direction) of the cabin base plate 10 correspondingly while opening the holes in the ventilation slot 102 of the cabin base plate 10; alternatively, the ventilation groove 102 of the cabin base plate 10 is perforated, and a second through hole or the like is formed in a portion of the conveyor belt 20 corresponding to the ventilation groove 102. The other modes based on the combination of the modes in the above embodiments can achieve the effects in the above exemplary modes after reasonable design, and are not described in detail herein.
In some exemplary embodiments, as shown in fig. 3 and 5 to 6, a step 104 is formed on the plate surface of the cabin base plate 10 corresponding to the second slot area, and the step 104 is used to support both edge portions of the conveyor belt 20. Considering that the pole piece 30 is affected by gravity, and the pole piece 30 is lower than two edge parts of the cabin base plate 10 after being absorbed by the absorption hole, a step 104 can be arranged on one side of the ventilation groove 102 away from the separation strip 105, and the edge part of the conveyor belt 20 is properly supported, so that the pole piece 30 is further prevented from being scratched. It should be noted that, the design height of the step 104 may be determined according to the thickness of the conveyor belt 20 and the gap between the conveyor belt 20 and the cabin base plate 10 during the working process, which is not described herein.
Based on the above embodiment, the sheet section pole piece 30 before the back hanging of the cutter die is skewed, and the flying piece rejection rate is reduced from about 0.4% to be close to 0.
Based on the embodiment, the negative electrode preset position can be reduced to be close to 0 due to the defect rate of about 0.2% caused by the deformation and tearing of the edge tab, abnormal CCD acquisition and pole piece scratch caused by negative pressure adsorption of the belt.
