Description

TECHNICAL FIELD

[0001] The utility model relates to battery manufacturing equipment technical field, in particular to a conveying device. BACKGROUND

[0002] In the battery manufacturing process, the pole piece material belt needs to be cut into pole pieces, and then the pole pieces are conveyed by using a belt conveying device. In the prior art, the belt conveying device comprises a conveying belt and a profile plate arranged below the conveying belt. The profile plate has a cavity, and a plurality of suction holes are formed on the conveying belt. A vacuum is drawn in the cavity of the profile plate to form a negative pressure at the suction holes. The pole pieces are adsorbed and fixed on the conveying belt by using the negative pressure, so that the pole pieces remain relatively fixed with the conveying belt during the conveying process.

[0003] However, in the actual production process, the vacuum loss of the cavity of the existing profile plate is relatively serious, which leads to insufficient and uneven adsorption force, so that the pole pieces are prone to bulging and edge lifting, and the pole pieces are prone to slipping relative to the conveying belt when the conveying belt starts and stops, thereby causing the quality and positioning accuracy of the pole pieces to decrease. SUMMARY

[0004] Therefore, it is necessary to provide a conveying device for improving the above-mentioned defects, which can solve the problem that the quality and positioning accuracy of the pole pieces decrease due to insufficient adsorption force when the pole pieces are conveyed by using the conveying belt in the prior art.

[0005] A conveying device comprises:

[0006] A groove plate, one side surface of the groove plate is inwardly recessed to form a negative pressure groove, and the groove plate further has a connecting hole in communication with the negative pressure groove, the connecting hole is used to communicate with an external negative pressure source through a pipeline;

[0007] An equalizing plate is arranged on the side of the groove plate having the negative pressure groove to cover the negative pressure groove, a plurality of air holes are formed on the equalizing plate, each air hole is in communication with the negative pressure groove and the side of the equalizing plate away from the groove plate; and

[0008] A conveying belt is arranged on the side surface of the equalizing plate away from the groove plate, and the conveying belt has a plurality of suction holes in communication with the negative pressure groove through the corresponding air holes.

[0009] In one of the embodiments, the groove plate comprises a bottom plate and two side plates, the two side plates are fixedly connected to the two side edges of the bottom plate in the width direction, so that the bottom plate and the two side plates jointly form the negative pressure groove, the connecting holes are arranged on the bottom plate, and the equalizing plate is arranged on the two side plates.

[0010] In one of the embodiments, the connecting holes are arranged in multiple, and the multiple connecting holes are arranged along the length direction of the bottom plate.

[0011] In one of the embodiments, the conveying device further comprises two end plates, the two end plates are arranged at the two ends of the bottom plate in the length direction, and are fixedly connected to the bottom plate and / or the two side plates to close the openings of the negative pressure groove at the two ends of the bottom plate in the length direction.

[0012] In one of the embodiments, the bottom plate and the two side plates are integrally formed.

[0013] In one of the embodiments, the back surface of the equalizing plate away from the groove plate is provided with multiple equalizing grooves, and each equalizing groove is provided with at least two air holes.

[0014] In one of the embodiments, each equalizing groove extends longitudinally along the length direction of the groove plate.

[0015] In one of the embodiments, each equalizing groove is arranged in multiple rows along the length direction of the groove plate, and each row of equalizing grooves is arranged along the width direction of the groove plate.

[0016] In one of the embodiments, each equalizing groove has the same shape and size, and the number of air holes in each equalizing groove is the same.

[0017] In one of the embodiments, the equalizing plate is arranged in multiple, and the multiple equalizing plates are arranged along the length direction of the groove plate.

[0018] In actual use, the external negative pressure source draws vacuum on the negative pressure groove through the connecting holes on the groove plate, so that the negative pressure groove is in a negative pressure state. A part of the conveying belt is supported on the equalizing plate and can be sequentially moved forward along the equalizing plate under control. The negative pressure in the negative pressure groove is transmitted to each adsorption hole on the conveying belt passing through the equalizing plate through each air hole on the equalizing plate. At this time, the workpiece to be conveyed is loaded on the conveying belt, so as to be adsorbed and fixed on the conveying belt by the negative pressure at the corresponding adsorption hole, and then the workpiece follows the conveying belt to be conveyed downstream.

[0019] Thus, the conveying device in this application utilizes a pressure equalizing plate to cover the negative pressure groove on the trough plate, and then uses various vents on the pressure equalizing plate to evenly transfer the negative pressure in the negative pressure groove to each adsorption hole on the conveyor belt. On the one hand, this greatly reduces vacuum loss, ensuring that the adsorption force on the workpiece is sufficiently large; on the other hand, the negative pressure at each vent is relatively uniform, thus making the negative pressure transmitted to each adsorption hole on the conveyor belt relatively uniform, and consequently, making the adsorption force on the workpiece relatively uniform. In other words, the adsorption force on the workpiece is sufficiently large and relatively uniform, thereby greatly reducing the risk of workpiece bulging, edge warping, and slippage relative to the conveyor belt when the conveyor belt starts and stops, thereby avoiding a decrease in workpiece quality and positioning accuracy.

[0030] Please refer to Figures 1 to 3The utility model provides an embodiment provides a kind of conveying device, including groove board 10, equalizing plate 20 and conveying belt 30.The side surface of this groove board 10 is recessed to form a negative pressure groove 112, the groove board 10 also has the connecting hole 110 being communicated with the negative pressure groove 112.The connecting hole 110 is used to be communicated with external negative pressure source by pipeline.External negative pressure source is extracted vacuum by the connecting hole 110 to negative pressure groove 112, so that negative pressure groove 112 is in negative pressure state.Equalizing plate 20 is arranged in the side of groove board 10 with negative pressure groove 112, to cover the negative pressure groove 112.Equalizing plate 20 is equipped with multiple air holes 21 (see Figure 3 ), each air hole 21 is all through the opposite sides of equalizing plate 20, to be communicated with negative pressure groove 112 and the side of equalizing plate 20 deviating from groove board 10.The conveying belt 30 can be controlled sequentially forward, and pass through the side surface of equalizing plate 20 deviating from groove board 10.The conveying belt 30 is equipped with multiple adsorption holes 31, and the adsorption hole 31 is communicated with negative pressure groove 112 by corresponding air hole 21, so that when external negative pressure source is extracted vacuum to negative pressure groove 112, the negative pressure in negative pressure groove 112 is transmitted to each adsorption hole 31 on the conveying belt 30 passing through equalizing plate 20 by each air hole 21 on equalizing plate 20, so that the workpiece to be conveyed is adsorbed and fixed on the conveying belt 30 using the negative pressure of each adsorption hole 31.

[0031] The conveying device described above, in actual use, external negative pressure source is extracted vacuum to negative pressure groove 112 by the connecting hole 110 on groove board 10, so that negative pressure groove 112 is in negative pressure state.A part of conveying belt 30 is supported on equalizing plate 20, and can be controlled sequentially forward along equalizing plate 20.The negative pressure in negative pressure groove 112 is transmitted to each adsorption hole 31 on the conveying belt 30 passing through equalizing plate 20 by each air hole 21 on equalizing plate 20.At this time, the workpiece to be conveyed is fed to the conveying belt 30, so as to be adsorbed and fixed on the conveying belt 30 by the negative pressure at corresponding adsorption hole 31, and then the workpiece follows the conveying belt 30 and is conveyed downstream.

[0032] Therefore, the conveying device in the application covers the negative pressure groove 112 on the groove plate 10 with the equalizing plate 20, and then uniformly transmits the negative pressure in the negative pressure groove 112 to each adsorption hole 31 of the conveying belt 30 through each air hole 21 on the equalizing plate 20. On the one hand, the transmission process between the negative pressure groove 112 and the conveying belt 30 is simplified, thereby greatly reducing the vacuum loss and ensuring that the adsorption force on the workpiece is large enough. On the other hand, the negative pressure at each air hole 21 is relatively uniform, thereby making the negative pressure transmitted to each adsorption hole 31 on the conveying belt 30 also relatively uniform, and further making the adsorption force on the workpiece also relatively uniform. That is, the adsorption force on the workpiece is large enough and relatively uniform, thereby greatly reducing the risk of the workpiece bulging, warping, and slipping relative to the conveying belt 30 when the conveying belt 30 starts and stops, and further avoiding the decline in the quality and positioning accuracy of the workpiece.

[0033] It should be noted that the workpiece in the present application can be a pole piece produced by die cutting or other processes, and can also be other products that need to be conveyed, which is not limited herein.

[0034] It should be further noted that the conveying device further comprises a tensioning mechanism for tensioning the conveying belt 30, which can adopt a relatively mature prior art, which is not limited herein. The conveying belt 30 can be driven to sequentially move along the equalizing plate 20 by using a motor, and the specific structure can adopt a relatively mature prior art, which is not limited herein.

[0035] Please refer to Figure 2 and Figure 4 In the embodiment of the application, the groove plate 10 comprises a bottom plate 11 and two side plates 13, which are respectively fixedly connected to the two side edges of the bottom plate 11 in the width direction of the bottom plate 11, so as to jointly enclose the negative pressure groove 112. The connecting hole 110 is formed in the bottom plate 11, and the equalizing plate 20 is installed on the two side plates 13. Alternatively, the bottom plate 11 and the two side plates 13 can adopt a profiled plate with a U-shaped cross section.

[0036] Further, the connecting holes 110 are arranged in multiple numbers and are arranged at intervals along the length direction of the bottom plate 11. In this way, each connecting hole 110 is communicated with the external negative pressure source through a pipeline, so that the external negative pressure source can simultaneously perform vacuumizing on the negative pressure groove 112 through each connecting hole 110, so that the negative pressure in the negative pressure groove 112 is more uniform, and further makes the adsorption force on the workpiece on the conveying belt 30 more uniform. In the embodiment shown in Figure 2 The number of the connecting holes 110 is 7, and can also be other numbers, such as 5, 6, 8, etc., which is set according to the length size of the groove plate 10 and other factors, which is not limited herein.

[0037] Further, the conveying device further comprises two end plates 40, which are respectively located at two ends of the bottom plate 11 in the length direction and are fixedly connected with the bottom plate 11 and / or the two side plates 13 to close the two end openings of the negative pressure groove 112 in the length direction of the bottom plate 11, so as to avoid the external air from entering the negative pressure groove 112 from the two end openings of the bottom plate 11 to cause vacuum loss. Alternatively, the end plate 40 is fixedly connected with the end of the bottom plate 11 and the two side plates 13 by screw locking. Of course, the end plate 40 can also be fixedly connected with the end of the bottom plate 11 and the two side plates 40 by welding, which is not limited here.

[0038] Please refer to Figure 2 and Figure 3 In the embodiments of the present application, the side surface of the equalizing plate 20 away from the groove plate 10 has a plurality of equalizing grooves 23. Each equalizing groove 23 has at least one air hole 21. In this way, the plurality of equalizing grooves 23 are arranged on the side surface of the equalizing plate 20 away from the groove plate 10, which on the one hand greatly reduces the contact area between the equalizing plate 20 and the conveying belt 30, thereby greatly increasing the area of the negative pressure formed on the side of the conveying belt 30 facing the equalizing plate 20, and further ensuring that the adsorption force on the workpiece is large enough; on the other hand, it can make the negative pressure more uniform, further improving the uniformity of the adsorption force on the workpiece. Alternatively, each equalizing groove 23 extends longitudinally along the length direction of the groove plate 10.

[0039] Further, each equalizing groove 23 is arranged in multiple rows along the length direction of the groove plate 10, and each row of equalizing grooves 23 is arranged at intervals along the width direction of the groove plate 10, so that the adsorption force on the workpiece on the conveying belt 30 remains stable during the movement of the conveying belt 30 along the equalizing plate 20, avoiding large fluctuations in the size and uniformity of the adsorption force on the workpiece on the conveying belt 30.

[0040] Further, the shape and size of each equalizing groove 23 are the same, and the number of air holes 21 in each equalizing groove 23 is the same, which further ensures that the adsorption force on the workpiece on the conveying belt 30 remains stable during the movement of the conveying belt 30 along the equalizing plate 20. In particular Figure 3 to the embodiment shown in the figure, each equalizing groove 23 has four air holes 21. Of course, in other embodiments, the number of air holes 21 in each equalizing groove 23 can also be two, three, five or six, etc., which is not limited here.

[0041] In the embodiments, the plurality of equalizing plates 20 are arranged along the length direction of the groove plate 10 and are fixedly connected to the two side plates 13. In this way, the length of each equalizing plate 20 is shortened, and the deformation and dimensional error of the equalizing plate 20 are reduced. Alternatively, each equalizing plate 20 can be fixedly connected to the two side plates 13 by screws. Of course, in other embodiments, each equalizing plate 20 can be fixedly connected to the two side plates 13 by welding, which is not limited herein.

[0042] It should be noted that the lengths of the equalizing plates 20 can be the same or different, as long as the total length is consistent with the length of the groove plate 10.

[0043] In other embodiments, only one equalizing plate 20 having a length consistent with the length of the groove plate 10 can be provided, as long as the dimensional error and deformation of the equalizing plate 20 meet the requirements, which is not limited herein.

[0044] The technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present disclosure.
