Description

Technical Field

[0001] This invention belongs to the field of conveying technology, specifically relating to a device for clamping objects, and more particularly to an electrode plate conveying device, an electrode plate detection system, and a method for operating the same. Background Technology

[0002] When AGV transport vehicles transfer pallets loaded with electrode plates, they often use fixed upper and lower clamping mechanisms or simple guiding structures for clamping and limiting, thereby preventing the electrode plates from shifting during the transport process.

[0003] This method is generally only used for square electrode plates. By limiting one side of the square electrode plate and then combining it with the clamping and limiting structure described above, the electrode plate can be prevented from shifting. However, the clamping and limiting structure described above cannot meet the conveying requirements of round electrode plates. Since round electrode plates do not have straight edges for limiting, when conveying them using the above clamping and limiting structure, the round electrode plates will still shift, resulting in errors in the initial position positioning. Subsequently, when the robotic arm grasps the round electrode plate, the end effector of the robotic arm often collides with the round electrode plate, causing wear and tear on the round electrode plate.

[0004] In related technologies, when transporting circular electrode plates, the only way to solve the problem of wear caused by offset is to improve the running accuracy of the robotic arm and the accuracy of the vision positioning system, which leads to excessively high transport costs for circular electrode plates.

[0005] Therefore, how to solve the deviation problem that occurs when AGV conveyors transport circular plates is an urgent issue to be addressed.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0007] This disclosure provides at least one electrode plate conveying device, an electrode plate detection system, and a method for operating the same.

[0008] In a first aspect, embodiments of this disclosure provide an electrode plate conveying device, comprising: outer frame; A circular tray is mounted on the outer frame; A rotating plate is disposed at the bottom of the circular tray; A driving component, used to drive the rotating plate to rotate; Multiple clamping rods are arranged at circumferential intervals along the rotating plate; The circular tray is provided with a plurality of arc-shaped sliding holes spaced apart along the circumference for the clamping rod to pass through; When conveying the circular electrode plates, the driving component drives the rotating plate to rotate, which in turn drives the clamping rod to rotate along the arc-shaped sliding hole, so as to clamp and adjust the stacked circular electrode plates on the circular tray to be concentric.

[0009] In one alternative embodiment, the arc-shaped sliding hole is arranged gradually closer to the axis along the circumference of the circular tray; When the driving member drives the rotating plate to rotate in the first direction, it drives the clamping rod to rotate along the arc-shaped sliding hole and gradually approach the axis of the circular tray to clamp the circular electrode plate and adjust it to be concentric. When the driving member drives the rotating plate to rotate in the second direction, it causes the clamping rod to rotate along the arc-shaped sliding hole and gradually move away from the axis of the circular tray, so as to release the clamping of the circular electrode plate.

[0010] In one alternative embodiment, the arc-shaped sliding hole has a notch with a guide surface at one end away from the axis of the circular tray; When the driving member drives the rotating plate to rotate in the second direction, the clamping rod disengages from the arc-shaped sliding hole along the guide surface of the notch and abuts against the side wall of the circular tray.

[0011] In one optional embodiment, the distance between the end of the arc-shaped sliding hole near the axis of the circular tray and the axis of the circular tray is R; The radius of the circular electrode is r; Wherein, R and r are size-matched, and the units of R and r are mm.

[0012] In one alternative embodiment, the top surface of the rotating plate is provided with a radial groove for sliding the clamping rod; The bottom of the clamping rod is elastically connected to the side wall of the slide groove away from the axis of the rotating plate by a return spring; When the driving component drives the rotating plate to rotate, it drives the clamping rod to rotate along the arc-shaped sliding hole. At the same time, the return spring pulls the clamping rod to clamp the circular electrode plate and adjust it to be concentric.

[0013] In one optional embodiment, the sidewall of the clamping rod is provided with a plurality of locking teeth spaced apart along the height direction; When the driving component drives the rotating plate to rotate, it causes the clamping rod to rotate along the arc-shaped sliding hole until the clamping teeth of the clamping rod abut against the side wall of the arc-shaped sliding hole. The arc-shaped sliding hole then pushes the clamping teeth downward, thereby causing the clamping rod to descend and thus reducing the height of the clamping rod.

[0014] In one optional implementation, the conveying of the circular electrode plate includes the following steps: The driving component drives the rotating plate to rotate in the first direction, which in turn drives the clamping rod to rotate along the arc-shaped sliding hole to clamp the circular electrode plate and adjust it to be concentric. When the teeth of the clamping rod abut against the side wall of the arc-shaped sliding hole, the arc-shaped sliding hole pushes the teeth downward, causing the clamping rod to descend. The driving component drives the rotating plate to rotate in the second direction, which in turn drives the clamping rod to rotate along the arc-shaped sliding hole, thereby releasing the clamping of the circular electrode plate so as to grasp the topmost circular electrode plate among the stacked circular electrode plates.

[0015] In one optional embodiment, when the clamping teeth of the clamping rod abut against the side wall of the arc-shaped sliding hole, the arc-shaped sliding hole pushes the clamping teeth down a distance H; The thickness of the circular electrode plate is d; Wherein, the dimensions of H and d are matched, and the units of H and d are mm.

[0016] Secondly, embodiments of this disclosure also provide an electrode plate detection system, comprising: The feeding and conveying mechanism is provided with a loading station, a picking station, a discharging station and an unloading station in sequence along the conveying direction; An AGV (Automated Guided Vehicle) is used to transport the electrode plate conveying device as described in claim 1 to the loading station and to transfer the electrode plate conveying device in the unloading station. A robotic arm is used to pick up circular electrode plates from the material handling station of the feeding and conveying mechanism, and to place the inspected circular electrode plates to the material dispensing station. The detection device is used to detect the circular electrode plates grasped by the robotic arm.

[0017] Thirdly, this disclosure also provides a method for operating the electrode plate detection system described above, the method comprising: The AGV transport vehicle places the electrode plate conveying device into the loading station; The feeding and conveying mechanism transports the electrode plate conveying device from the loading station to the unloading station; The robotic arm grabs the circular electrode plate from the loading station; A robotic arm transports the circular electrode plate to the testing device for testing. The robotic arm places the inspected circular electrode plates onto the electrode plate conveying device at the feeding station for stacking. The feeding and conveying mechanism transports the electrode plate conveying device in the feeding station to the unloading station; The AGV transport vehicle removes the electrode plate conveying device from the unloading station and completes the inspection.

[0018] The beneficial effects of this invention are as follows: the electrode plate conveying device, electrode plate detection system, and method of use thereof include: an outer frame; a circular tray disposed on the outer frame; a rotating plate disposed at the bottom of the circular tray; a driving member for driving the rotating plate to rotate; and a plurality of clamping rods spaced apart circumferentially along the rotating plate; wherein the circular tray has a plurality of arc-shaped sliding holes spaced apart circumferentially for the clamping rods to pass through; when conveying the circular electrode plates, the driving member drives the rotating plate to rotate, thereby causing the clamping rods to rotate along the arc-shaped sliding holes, so as to clamp and adjust the stacked circular electrode plates on the circular tray to concentricity. By driving the clamping rod to move synchronously along the arc-shaped sliding hole by rotating the plate, multiple clamping points form radial multi-point support, reducing the clamping force required when clamping the circular electrode plate, thereby reducing the wear of the circular electrode plate. At the same time, it improves the concentricity of the stacked circular electrode plates and improves the positioning accuracy of the circular electrode plate. Without affecting the normal gripping of the robotic arm, it reduces the accuracy requirements of the robotic arm during gripping and lowers the cost of transporting the circular electrode plate.

[0030] Research has revealed that in related technologies, when AGV transport vehicles transport circular electrode plates, a fixed clamping mechanism is used to transport pallets stacked with circular electrode plates. If the clamping force of the fixed upper and lower clamping mechanism is too loose, the circular electrode plates are prone to shifting, causing wear between the circular electrode plates. If the clamping force of the fixed clamping mechanism is too tight, it will cause wear at the clamping points. If the clamping mechanism is set to radial clamping, it will interfere with the gripping of the robotic arm. Therefore, in existing technologies, the concentricity of the circular electrode plates is generally adjusted manually, resulting in excessively high costs for electrode plate transport.

[0031] Based on the above research, this disclosure provides an electrode plate conveying device 100, an electrode plate detection system, and their working method. By driving the clamping rod 150 to move synchronously along the arc-shaped sliding hole 121 through the rotating plate 130, multiple clamping points clamp the circular electrode plate 200 radially, forming radial multi-point support, which reduces the clamping force when clamping the circular electrode plate 200. At the same time, the synchronous force from multiple points can improve the concentricity of the stacked circular electrode plates 200 and improve the positioning accuracy of the circular electrode plates 200. Without affecting the normal gripping of the robotic arm 400, the accuracy requirements of the robotic arm 400 during gripping are reduced, and the cost of conveying the circular electrode plate 200 is reduced.

[0032] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] Please see Figure 1 and Figure 2 At least one embodiment provides an electrode plate conveying device 100, including: an outer frame 110; a circular tray 120 disposed on the outer frame 110; a rotating plate 130 disposed at the bottom of the circular tray 120; a driving member 140 for driving the rotating plate 130 to rotate; and a plurality of clamping rods 150 spaced apart circumferentially along the rotating plate 130; wherein the circular tray 120 has a plurality of arc-shaped sliding holes 121 spaced apart circumferentially for the clamping rods 150 to pass through; when conveying the circular electrode plates 200, the driving member 140 drives the rotating plate 130 to rotate, thereby causing the clamping rods 150 to rotate along the arc-shaped sliding holes 121, so as to clamp and adjust the stacked circular electrode plates 200 on the circular tray 120 to concentricity.

[0036] The rotating plate 130 drives the clamping rod 150 to move synchronously along the arc-shaped sliding hole 121, so that multiple clamping points form radial multi-point support, reducing the clamping force when clamping the circular electrode plate 200, thereby reducing the wear of the circular electrode plate 200. At the same time, it improves the concentricity of the stacked circular electrode plates 200 and improves the positioning accuracy of the circular electrode plate 200. Without affecting the normal gripping of the robotic arm 400, it reduces the accuracy requirements of the robotic arm 400 during gripping and lowers the cost of transporting the circular electrode plate 200.

[0037] Please see Figure 3 The arc-shaped sliding hole 121 is arranged gradually closer to the axis along the circumference of the circular tray 120; the driving member 140 drives the rotating plate 130 to rotate in the first direction (e.g. Figure 3 When the clamping rod 150 is driven to rotate along the arc-shaped sliding hole 121 (as shown in F1), it gradually approaches the axis of the circular tray 120 to clamp and adjust the circular electrode plate 200 to be concentric; when the driving member 140 drives the rotating plate 130 to rotate in the second direction (as shown in F1), the clamping rod 150 rotates along the arc-shaped sliding hole 121 and gradually approaches the axis of the circular tray 120 to clamp and adjust the circular electrode plate 200 to be concentric; Figure 3 When (as shown in F2), the clamping rod 150 is driven to rotate along the arc-shaped sliding hole 121 and gradually move away from the axis of the circular tray 120 to release the clamping of the circular electrode plate 200.

[0038] The arc-shaped sliding hole 121 has a gradually shrinking structure along the circumference. Combined with the bidirectional controllable rotation of the rotating plate 130, it realizes the gradual retraction and release of the clamping rod 150, thereby avoiding interference with the gripping of the robotic arm 400 and not affecting the subsequent conveying of the circular electrode plate 200.

[0039] Please continue reading. Figure 3 The arc-shaped sliding hole 121 has a notch 121a with a guide surface 121b at one end away from the axis of the circular tray 120; when the driving member 140 drives the rotating plate 130 to rotate in the second direction, the clamping rod 150 disengages from the arc-shaped sliding hole 121 along the guide surface 121b of the notch 121a and abuts against the side wall of the circular tray 120.

[0040] A notch 121a for disengagement is provided at the end of the arc-shaped sliding hole 121, so that the clamping rod 150 can quickly disengage from the edge of the electrode plate through mechanical limiting when rotating in the second direction, and abut against the side wall of the circular tray 120 through the guide surface 121b, which facilitates the gripping of the robotic arm 400.

[0041] To ensure the clamping effect of the clamping rod 150, in a preferred embodiment, the distance between the end of the arc-shaped sliding hole 121 near the axis of the circular tray 120 and the axis of the circular tray 120 is R; the radius of the circular electrode plate 200 is r; wherein R and r are matched, and the units of R and r are mm. It should be noted that the matching of R and r is sufficient, and a flexible buffer layer is provided on the abutment surface of the clamping rod 150 and the circular electrode plate 200 to accommodate accuracy errors.

[0042] Please see Figure 1 and Figure 4 The top surface of the rotating plate 130 is radially provided with a sliding groove 131 for the clamping rod 150 to slide; the bottom of the clamping rod 150 is elastically connected to the side wall of the sliding groove 131 away from the axis of the rotating plate 130 through a return spring 132; when the driving member 140 drives the rotating plate 130 to rotate, it drives the clamping rod 150 to rotate along the arc-shaped sliding hole 121. At the same time, the return spring 132 pulls the clamping rod 150 to clamp the circular electrode plate 200 and adjust it to be concentric.

[0043] The return spring 132 and the slide groove 131 work together to form an elastic buffer system, which avoids excessive dynamic impact force on a certain clamping point when adjusting the concentricity of the circular electrode plate 200. At the same time, the clamping rod 150 is pushed, thereby driving the clamping rod 150 to adjust the position of the side wall of the circular electrode plate 200. In conjunction with the guide adjustment of the arc-shaped sliding hole 121, the concentricity of the stacked circular electrode plates 200 is further improved.

[0044] Please see Figure 2 and Figure 4 The sidewall of the clamping rod 150 is provided with a plurality of locking teeth 151 at intervals along the height direction; when the driving member 140 drives the rotating plate 130 to rotate, it drives the clamping rod 150 to rotate along the arc-shaped sliding hole 121 until the locking teeth 151 of the clamping rod 150 abut against the sidewall of the arc-shaped sliding hole 121, the arc-shaped sliding hole 121 pushes the locking teeth 151 to move downward, thereby driving the clamping rod 150 to descend, and thus reducing the height of the clamping rod 150.

[0045] The triangular teeth 151 on the side wall of the clamping rod 150 engage with the side wall of the arc-shaped sliding hole 121, and when the rotating plate 130 rotates in the first direction, it triggers the clamping rod 150 to move axially downward (e.g. Figure 4 As shown in Figure F, the circular electrode 200, which is precisely matched to the gripping plane of the robotic arm 400, is moved to expose the top circular electrode 300, making it easier for the robotic arm 400 to grip it.

[0046] Specifically, the conveying of the circular electrode plate 200 includes the following steps: In step S1, the driving component 140 drives the rotating plate 130 to rotate in the first direction, thereby causing the clamping rod 150 to rotate along the arc-shaped sliding hole 121 to clamp the circular electrode plate 200 and adjust it to be concentric.

[0047] In step S2, when the locking teeth 151 of the clamping rod 150 abut against the side wall of the arc-shaped sliding hole 121, the arc-shaped sliding hole 121 pushes the locking teeth 151 downward, causing the clamping rod 150 to descend.

[0048] In step S3, the driving member 140 drives the rotating plate 130 to rotate in the second direction, which in turn drives the clamping rod 150 to rotate along the arc-shaped sliding hole 121, thereby releasing the clamping of the circular electrode plate 200 so as to grasp the topmost circular electrode plate 200 among the stacked circular electrode plates 200.

[0049] After executing step S2, the end effector of the robotic arm 400 will grasp the released circular electrode plate 200. Then, in step S3, after the clamping rod 150 clamps the remaining circular electrode plate 200, the robotic arm 400 will separate the circular electrode plate 200 from the remaining circular electrode plate 200, thereby preventing the robotic arm 400 from causing the next layer of circular electrode plates 200 to shift when grasping the circular electrode plate 200.

[0050] It should be noted that when the clamping teeth 151 of the clamping rod 150 abut against the side wall of the arc-shaped sliding hole 121, the distance by which the arc-shaped sliding hole 121 pushes the clamping teeth 151 downward is H; the thickness of the circular electrode plate 200 is d; wherein, the dimensions of H and d are matched, and the units of H and d are mm.

[0051] Please see Figure 5 At least one embodiment also provides an electrode plate detection system, comprising: a feeding and conveying mechanism 300, which is sequentially arranged along the conveying direction with a loading station 310, a picking station 320, a discharging station 330, and a unloading station 340; an AGV conveyor vehicle, which is used to transport the electrode plate conveying device 100 as described in claim 1 to the loading station 310 and to transfer the electrode plate conveying device 100 in the unloading station 340; a robotic arm 400, which is used to grab a circular electrode plate 200 from the picking station 320 of the feeding and conveying mechanism 300 and to place the inspected circular electrode plate 200 to the discharging station 330; and a detection device, which is used to detect the circular electrode plate 200 grabbed by the robotic arm 400.

[0052] By integrating AGV transfer, 400-degree robotic arm gripping, and inspection station into a continuous conveyor line, the flow time of the electrode plates from loading to finished product unloading is shortened.

[0053] Please see Figure 6At least one embodiment also provides a method of operation applied to the electrode detection system as described above, the method comprising: S110, the AGV transport vehicle places the electrode plate conveying device 100 into the loading station 310.

[0054] S120, the feeding and conveying mechanism 300 conveys the electrode plate conveying device 100 from the loading station 310 to the unloading station 320.

[0055] S130, the robotic arm 400 grabs the circular electrode plate 200 in the loading station 310.

[0056] Specifically, step S130 includes the following steps: In step S1, the driving component 140 drives the rotating plate 130 to rotate in the first direction, thereby causing the clamping rod 150 to rotate along the arc-shaped sliding hole 121 to clamp the circular electrode plate 200 and adjust it to be concentric.

[0057] In step S2, when the locking teeth 151 of the clamping rod 150 abut against the side wall of the arc-shaped sliding hole 121, the arc-shaped sliding hole 121 pushes the locking teeth 151 downward, causing the clamping rod 150 to descend.

[0058] In step S3, the driving member 140 drives the rotating plate 130 to rotate in the second direction, which in turn drives the clamping rod 150 to rotate along the arc-shaped sliding hole 121, thereby releasing the clamping of the circular electrode plate 200 so as to grasp the topmost circular electrode plate 200 among the stacked circular electrode plates 200.

[0059] After executing step S2, the end effector of the robotic arm 400 will grasp the released circular electrode plate 200. Then, in step S3, after the clamping rod 150 clamps the remaining circular electrode plate 200, the robotic arm 400 will separate the circular electrode plate 200 from the remaining circular electrode plate 200, thereby preventing the robotic arm 400 from causing the next layer of circular electrode plates 200 to shift when grasping the circular electrode plate 200.

[0060] S140, the circular electrode plate 200 is transported to the testing device for testing by the robotic arm 400.

[0061] S150, the robotic arm 400 places the inspected circular electrode plates 200 onto the electrode plate conveying device 100 at the feeding station 330 for stacking.

[0062] S160, the feeding and conveying mechanism 300 conveys the electrode plate conveying device 100 in the unloading station 330 to the unloading station 340.

[0063] S170, the AGV transport vehicle removes the electrode plate conveying device 100 from the unloading station 340 to complete the inspection.

[0064] In summary, the present invention provides an electrode plate conveying device 100, an electrode plate detection system, and a method of using the same. The electrode plate conveying device 100 includes: an outer frame 110; a circular tray 120 disposed on the outer frame 110; a rotating plate 130 disposed at the bottom of the circular tray 120; a driving member 140 for driving the rotating plate 130 to rotate; and a plurality of clamping rods 150 spaced apart circumferentially along the rotating plate 130. The circular tray 120 has a plurality of arc-shaped sliding holes 121 spaced apart circumferentially for the clamping rods 150 to pass through. When conveying the circular electrode plates 200, the driving member 140 drives the rotating plate 130 to rotate, thereby causing the clamping rods 150 to rotate along the arc-shaped sliding holes 121, so as to clamp and adjust the stacked circular electrode plates 200 on the circular tray 120 to concentricity. By driving the clamping rod to move synchronously along the arc-shaped sliding hole via a rotating plate, multiple clamping points form radial multi-point support, reducing the clamping force required when clamping the circular electrode plate, thereby reducing wear on the circular electrode plate. Simultaneously, it improves the concentricity of the stacked circular electrode plates, thus improving the positioning accuracy of the circular electrode plate. Without affecting the normal gripping function of the robotic arm, it reduces the precision requirements for the robotic arm's gripping, lowering the cost of transporting the circular electrode plate.

In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0067] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0068] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
