Fig. 2 is a schematic view of a pole piece conveying device according to an embodiment of the present application. The pole piece transport device 60 in this embodiment may include a first mechanism 61 and a second mechanism 66. The first mechanism 61 is used for supporting the lower surface of the pole piece 2, and the pole piece 2 can be a positive pole piece or a negative pole piece. The second mechanism 66 is used to pick up the pole piece 2 from the first mechanism 61 by contacting and fixing the upper surface of the pole piece 2. At least one of the first mechanism 61 and the second mechanism 66 is arranged to move to expose the lower surface of the pole piece 2 picked up by the second mechanism 66.

The first mechanism 61 may have a support platform for supporting the lower surface of the pole piece 2 and correspondingly exposing the upper surface of the pole piece 2. The first mechanism 61 may be stationary to keep the pole piece 2 stationary after supporting the pole piece 2. The first mechanism 61 may also be movable to transport the pole piece 2 to a predetermined position after supporting the pole piece 2.

The second mechanism 66 may have a pick-up platform for contacting and securing the upper surface of the pole piece 2. When the first mechanism 61 is arranged stationary, the second mechanism 66 may be arranged to be movable in order to move over the first mechanism 61 and pick up a pole piece 2. The second mechanism 66 may also be stationary, in which case the first mechanism 61 is arranged to be movable, so that after supporting the pole piece 2, the pole piece 2 is transported under the second mechanism 66, and the second mechanism 66 picks up the pole piece 2. In addition, the first mechanism 61 and the second mechanism 66 can be movably arranged so as to cooperate with the movement to a preset position to carry out the transfer of the pole piece 2, and further move to expose the lower surface of the pole piece 2 picked up by the second mechanism 66.

The movement of the first mechanism 61 and the second mechanism 66 may be the entire movement of the first mechanism 61 and the second mechanism 66, or may be the movement of parts of the first mechanism 61 and the second mechanism 66. For example, in order to enable the first mechanism 61 to transport the pole piece 2 to a predetermined position, the first mechanism 61 may drive the whole pole piece 2 to move, or one component of the first mechanism 61 may drive the pole piece 2 to move relative to other components of the first mechanism 61. In addition, the second mechanism 66 can pick up the pole piece 2 by a vacuum adsorption mode, a magnetic adsorption mode, a viscous adsorption mode, and the like.

In the pole piece conveying device 60 of the above embodiment, the second mechanism 66 picks up the pole piece 2 from the first mechanism 61, and the lower surface of the pole piece 2 picked up by the second mechanism 66 is exposed, so that the pole piece 2 can be conveyed to a state convenient for carrying. That is, since the lower surface of the pole piece 2 picked up by the second mechanism 66 is exposed and is not adsorbed or fixed by the second mechanism, the pole piece 2 is in a state convenient for carrying, and the exposed lower surface of the pole piece can be adsorbed from the lower part of the pole piece 2 by the carrying assembly and can be rapidly carried to the lower surface of the diaphragm, so that the carrying efficiency of the pole piece 2 can be improved.

Please refer to fig. 3, which is a schematic front view of a pole piece conveying apparatus according to another embodiment of the present disclosure. The pole piece transport device 60 in this embodiment may include a first mechanism 61 and a second mechanism 66 disposed adjacent to the first mechanism 61.

In the embodiment shown in fig. 3, the first mechanism 61 may include: a first conveyor belt 62 for contacting and conveying the pole piece 2 towards the upward first surface 621, the pole piece 2 being either a positive pole piece or a negative pole piece; a first conveyor belt driving mechanism 63 for driving the first conveyor belt 62 to operate; a first base plate 64, around which the first conveyor belt 62 may be wound, to be better supported by the first base plate 64. Since the outer surface of the first belt 62 is shifted between upward and downward during the operation, the first surface 621 is defined as the surface of the first belt 62 that faces upward during the operation.

In an embodiment, as shown in fig. 4, a detection mark 623 is disposed on the first conveyor belt 62 along the conveying direction a1 of the first conveyor belt 62. The first mechanism 61 may further include: a first detecting member 613, disposed corresponding to a first position A3, for detecting whether the detection mark 623 passes through the first position A3; wherein the first position a3 is located on the trajectory of the detection mark 623; a control system 614, connected to the first detecting element 613, for controlling starting and stopping of the first conveyor belt 62 according to a detection result of the first detecting element 613. Specifically, the control system 614 can control the start and stop of the first conveyor belt driving mechanism 63, and further control the start and stop of the first conveyor belt 62 driven by the first conveyor belt driving mechanism 63.

In one embodiment, the number of the detection marks 623 is multiple. Further, a plurality of the detection marks 623 may be disposed at equal intervals.

In an embodiment, the detection mark 623 is a detection hole formed on the first conveyor belt 62 or a label disposed on the first conveyor belt 62.

In an embodiment, a plurality of the detection marks 623 may be disposed at equal intervals, and the first detecting member 613 may be disposed on the first base plate 64 and configured to detect the amount of the detection marks 623 passing through the first position a 3. It is understood that each time the first detecting member 613 detects one detection mark 623, the number of the detection marks 623 detected at the current time is counted to obtain the amount value of the detection marks 623 detected cumulatively at the current time.

In one embodiment, the first detecting element 613 may be a sensor; such as a fiber optic sensor.

In an embodiment, the control system 614 can control the start and stop of the first conveyor belt 62 according to whether the first detecting member 613 detects the detection mark 623. Specifically, when the first detecting element 613 detects the detection mark 623, the first detecting element 613 feeds back the detection result to the control system 614, and the control system 614 controls the first conveyor belt 62 to stop operating according to the detection result, and after the next pole piece 2 is conveyed and adsorbed to the surface of the first conveyor belt 62, the control system 614 controls the first conveyor belt 62 to start to continue to operate the first conveyor belt 62; when the first detecting member 613 does not detect the detection mark 623, the first conveyor belt 62 continues to operate. When the distances between the detection marks 623 on the first conveyor belt 62 are equal, the control system 614 controls the start and stop of the first conveyor belt 62 according to whether the first detection piece 613 detects the detection marks 623, so that the first conveyor belt 62 stops running after running for a predetermined distance every time, and then the pole piece 2 is conveyed to the surface of the first conveyor belt 62; therefore, the equal distance between the electrode plates 2 conveyed to the surface of the first conveyor belt 62 can be effectively ensured, and each electrode plate 2 can be accurately conveyed to a set station.

In an embodiment, the control system 614 can control the start and stop of the first conveyor belt 62 according to whether the number of the detection marks 623 detected by the first detecting element 613 reaches a preset threshold; the preset threshold may be two or three, or of course, may be one of the above; specifically, when the quantity value of the detection mark 623 detected by the first detecting element 613 reaches a preset threshold, the first detecting element 613 feeds back the detection result to the control system 614, and the control system 614 controls the first conveyor belt 62 to stop operating according to the detection result, and after the next pole piece 2 is conveyed and adsorbed to the surface of the first conveyor belt 62, the first conveyor belt 62 continues to operate; when the number of the detection marks 623 detected by the first detecting element 613 is smaller than the preset threshold (i.e., the preset threshold is not reached), the first conveyor belt 62 continues to operate; because the distances between the detection marks 623 on the first conveyor belt 62 are equal, when the first detection element 613 detects a certain number of detection marks 623, the distances between the corresponding first conveyor belts 62 are the same, so that the first conveyor belt 62 is controlled by the control system 614 to stop running after the first conveyor belt 62 runs the same distance, and then the pole pieces 2 are transported to the surface of the first conveyor belt 62 and are adsorbed, thereby effectively ensuring that the distances between the pole pieces 2 transported to the surface of the first conveyor belt 62 are equal, and enabling each pole piece 2 to be accurately transported to a set station. It is understood that, in this embodiment, the first detecting member 613 counts the number of the detected detection marks 623 again every time the first conveyor belt 62 stops running. The control system 614 may also control the operation of other relevant portions of the pole piece transfer device 60 or may be integrated with other control systems that control the operation of other relevant portions of the pole piece transfer device 60 into a unitary control system.

In one embodiment, the first belt driving mechanism 63 may include: two rollers 631 respectively disposed at opposite ends of the first base plate 64; a drive roller 632 disposed on the underside of the first base plate 64. The first belt 62 may be wound around a roller 631 and a driving roller 632 and supported on an upper side surface of the first base plate 64.

In an embodiment, a tension wheel 633 is further disposed between the driving roller 632 and the roller 631 to adjust the tightness degree of the first belt 62; further, a tension adjusting mechanism 634 is disposed on the tension wheel 633 to adjust the movement of the tension wheel 633 in a direction perpendicular to the plane of the first base plate 64, for example.

The second mechanism 66 may include: a second conveyor 67 having a second surface 671 facing downward, and the second surface 671 and the first surface 621 have an overlapping region a2 in the conveying direction a1 of the first conveyor 62, for example, a region where the end of the first conveyor 62 overlaps with the start end of the second conveyor 67 (which may have a vacuum suction effect on the pole piece 2); a second conveyor belt driving mechanism 68 for driving the second conveyor belt 67 to operate; a second floor 69, around which the second conveyor 67 can be wound, for better support thereof by the first floor 64. The second surface 671 of the second conveyor 67 is defined herein as the surface that faces downwardly when it is operated, since the surface of the second conveyor 67 on its outside will alternate between upwardly and downwardly when it is operated. Said second surface 671 and said first surface 621 may have a gap in a direction perpendicular to the transport direction a1, which may be comparable to the thickness of the pole piece 2 for the passage of the pole piece 2 and facilitate the interface of the pole piece 2 between the first mechanism 61 and the second mechanism 66. As shown in fig. 3, the first mechanism 61 and the second mechanism 66 being adjacent means that the first mechanism 61 and the second mechanism 66 are disposed adjacent to each other; specifically, the second mechanism 66 is disposed above the first mechanism 61, and is disposed such that the second surface 671 of the second conveyor belt 67 and the first surface 621 of the first conveyor belt 62 have an overlap area a2 in the conveying direction a1 of the first conveyor belt 62.

In one embodiment, the second conveyor drive mechanism 68 may be similar to the first conveyor drive mechanism 63 described above. Specifically, the second belt drive mechanism 68 may include: two rollers 691 (see fig. 4) provided at opposite ends of the second bottom plate 69, respectively; a driving roller 692 provided on the upper side of the second base plate 69. The second belt 67 may be wound around rollers 691 and a driving roller 692 and supported on a lower side surface of the second floor 69.

In an embodiment, a tension wheel 693 may be further disposed between the driving roller 692 and the roller 691 to adjust the tightness degree of the second conveyor 67; likewise, the tensioning wheel 693 may also be provided with a tensioning adjustment mechanism similar to the tensioning adjustment mechanism 634 described above to adjust the movement of the tensioning wheel 693 in a direction, for example, perpendicular to the plane of the second base plate 69.

In the operation of the pole piece conveying device 60, the first conveyor belt driving mechanism 63 drives the first conveyor belt 62 to run along the conveying direction a1 to convey the pole piece 2 to the overlapping region a 2; the second conveyor 67 picks up the pole piece 2 at the overlap area a2 by the second surface 671 and continues to convey the pole piece 2 via the drive of the second conveyor drive mechanism 68. The direction in which the pole piece 2 is conveyed further by the second conveyor 67 may be the same as the conveying direction a1, or may be perpendicular or at an angle. The second conveyor belt 67 can pick up the pole pieces 2 in a vacuum adsorption mode, a magnetic adsorption mode, a viscous adsorption mode and the like.

Reference is made to fig. 5, which is a schematic top view of the first base plate 64 of the first mechanism 61 of the pole piece transfer device 60 shown in fig. 3. In an embodiment, the first base plate 64 has a plurality of first base plate absorption holes 641 on a surface contacting with the first conveyor belt 62, and a plurality of vacuuming holes 643 are disposed at intervals. Each first bottom plate absorption hole 641 may be a long groove formed on the surface of the first bottom plate 64, and may extend along the length direction a4 of the first bottom plate 64; each of the vacuuming holes 643 may be a through hole perpendicular to the length direction a4 of the first bottom plate 64. The longitudinal direction a4 may be the same direction as the conveying direction a1 of the first conveyor belt 62. Each of the vacuuming holes 643 may communicate with a part or all of the plurality of first chassis adsorption holes 641. Accordingly, the first conveyor belt 62 may be provided with a first conveyor belt suction hole 622 (see fig. 4) communicating with the first base plate suction hole 641. The first belt suction hole 622 may be a circular hole or a kidney-shaped hole. The first bottom plate adsorption hole 641 may be connected to the vacuum pumping device 611 through a vacuum pumping hole 643 and a vacuum pumping joint 644 connected to the vacuum pumping hole 643, so that when the vacuum pumping device 611 operates, the pole piece 2 is adsorbed to the first surface 621 of the first conveyor belt 62, so as to prevent the pole piece 2 from being relatively displaced from the first conveyor belt 62 due to vibration of the first conveyor belt 62 or sudden start and stop of the first conveyor belt 62 during transmission, and further ensure that the pole piece 2 can be stably and synchronously transmitted to a preset position through the first conveyor belt 62. The evacuation device 611 may be a vacuum pump.

In an embodiment, the first mechanism 61 further includes a first vacuum breaking assembly 612, and the first vacuum breaking assembly 612 is communicated with a first conveyor belt suction hole 622 corresponding to the overlap area a2, and is used for providing gas to the surface of the pole piece 2 facing the first bottom plate 64 when the pole piece 2 is conveyed to the overlap area a 2. For example, the first vacuum breaking assembly 612 may communicate with the vacuum holes 643 at the overlapping area a2 through the air inlets 642 formed on the first bottom plate 64, so as to allow air to pass through. Therefore, the pressure of the inlet gas is greater than the negative pressure of the evacuation through the inlet gas, and the pole piece 2 at the tail end of the first mechanism 61 is broken to be evacuated. In one embodiment, the first vacuum breaking element 612 may be a high pressure air source, and an air outlet of the high pressure air source may be connected to the air inlet 642 through a ventilation joint. When it is required to detach the pole piece 2 on the first conveyor belt 62 from the first conveyor belt 62, compressed air from a high-pressure air source enters the vacuuming hole 643 and blows toward the side surface of the pole piece 2 close to the first base plate 64, so as to detach the pole piece 2 from the surface of the first conveyor belt 62.

Referring to fig. 6 to 9, wherein fig. 6 is a schematic top view of the second mechanism 66 of the pole piece transport device 60 shown in fig. 3, fig. 7 is a schematic cross-sectional view of the second mechanism 66 in fig. 6, fig. 8 is a schematic diagram of the smoothing mechanism 662 of the second mechanism 66 in fig. 6, and fig. 9 is a schematic bottom view of the second bottom plate 69 of the second mechanism 66 in fig. 6.

In one embodiment, as shown in fig. 9, the second base plate 69 is provided with a plurality of second base plate suction holes 691 on a surface contacting with the second conveyor 67, and a plurality of vacuuming holes 694 are provided at intervals. Each of the second bottom plate suction holes 691 may be an elongated groove opened in the surface of the second bottom plate 69 and extend in the longitudinal direction a5 of the second bottom plate 69; each of the vacuuming holes 694 may be a through hole perpendicular to the length direction a5 of the second bottom plate 69. Each of the vacuuming holes 694 may communicate with part or all of the plurality of second floor suction holes 691. Accordingly, the second conveyor 67 may be provided with a second conveyor suction hole 672 (see fig. 6) communicating with the second floor suction hole 691. The second belt suction holes 672 may be circular holes or kidney-shaped holes. The second bottom plate adsorption hole 691 can be connected with a vacuumizing device 661 through a vacuumizing hole 694 and a vacuumizing joint 695 connected with the vacuumizing hole 694, so that when the vacuumizing device 661 works, the pole piece 2 is adsorbed on the second surface 671 of the second conveyor belt 67, and therefore the pole piece 2 is prevented from being displaced relative to the second conveyor belt 67 due to vibration of the second conveyor belt 67 or sudden start and stop of the second conveyor belt 67 during transmission, and further the pole piece 2 can be stably and synchronously transmitted to a preset position through the second conveyor belt 67. It can be seen that the principle of the suction of the pole piece 2 by the second mechanism 66 can be basically the same as the principle of the suction of the pole piece 2 by the first mechanism 61.

In one embodiment, the evacuation device 661 can be a vacuum pump. The vacuum-pumping device 661 may be the same vacuum-pumping device as the vacuum-pumping device 611.

In an embodiment, as shown in fig. 3 and 8, the second mechanism 66 may further include a smoothing mechanism 662, and the smoothing mechanism 662 is configured to smooth the pole piece 2 delivered from the overlapping area a2, so that the entire pole piece 2 is uniformly attached to the second surface 671 of the second conveyor belt 67. The smoothing mechanism 662 may include a roller 6621, a smoothing seat 6622, and a link 6623. Said cylinder 6621 may be mounted on said smoothing seat 6622, said smoothing seat 6622 being mounted on two links 6623. Thus, when the link 6623 is mounted on the second mechanism 66 and the roller 6621 is brought close to the second surface 671, the roller 6621 can smooth the pole piece 2 delivered from the overlap region a 2. Further, the pacifier 6622 may be slidably disposed over the two links 6623, and an elastic member 6624 may be disposed on the link 6623 to apply a force to the pacifier 6622 toward the second surface 671. The elastic member 6624 may be a spring, elastic rubber, or the like.

In an embodiment, as shown in fig. 3 and 10, the second mechanism 66 further includes a handling assembly 663, and the handling assembly 663 is used for grabbing the pole piece 2 at the material taking station on the second surface 671 of the second conveyor belt 67 through an adsorption plate 667 and handling the pole piece to the lamination station D. For example, the carrying assembly 663 may adopt a robot, the adsorption plate 667 may be fixedly disposed at a moving end of the robot, and the adsorption plate 667 is driven by the robot to adsorb the pole piece 2 at the material taking station of the second conveyor belt.

In an embodiment, as shown in fig. 7 and 9, a groove 692 may be formed on a lower surface of the second bottom plate 69, and a cover plate 693 covers an opening of the groove 692. The second mechanism 66 may further include: a light source 664 arranged in the groove 692 for irradiating the positioning detection area C1, wherein the cover plate 693 can transmit light emitted by the light source 664; an image capturing device 665, disposed on a side of the cover plate 693 away from the light source 664, is capable of receiving light transmitted through the cover plate 693, so as to be used for capturing image information of the pole piece 2 located in the positioning detection area C1, for example, by taking a picture. Correspondingly, the carrying assembly 663 is in communication connection with the image acquisition device 665, and is used for correcting the position of the pole piece 2 according to the image information acquired by the image acquisition device 665 after the pole piece 2 is grabbed. The positioning detection area C1 may be identical to the reclaiming station described above.

In an implementation, the light source 664 may be a light source emitting visible light (e.g., white, blue, red light, etc.), the cover 693 may be a transparent plate, and the second transmission belt 67 may be a transparent belt to improve the penetrating power of the light emitted by the light source 664. In other embodiments, the light source 664 may be a light source emitting only specific light (e.g., infrared or ultraviolet light), the cover 693 and the second conveyor 67 may transmit only such specific light (e.g., infrared or ultraviolet light), and the corresponding image capture device 665 may capture an image of such specific light.

It can be understood that, when the pole piece 2 is located in the positioning detection area C1, the light source 664 irradiates the pole piece 2 from the side of the pole piece 2 close to the second bottom plate 69, and the image acquisition device 665 acquires the image information of the pole piece 2 from the side of the pole piece 2 away from the second bottom plate 69, so as to highlight the edge of the pole piece 2, thereby improving the imaging quality of the pole piece 2, and further improving the accuracy of the acquired image information of the pole piece 2. The image information of the pole piece 2 may specifically include size information and current position information of the pole piece 2, wherein the current position information of the pole piece 2 may specifically include coordinate information along an X direction, a Y direction, and a Z direction (see fig. 3 and 4).

In one embodiment, image capture device 665 can be a camera; for example, a CCD camera; the positioning detection region C1 may be the region where the pole piece 2 is positioned above the light source 664, for example, it may be the region corresponding to the opening of the groove 692.

Specifically, the length and width of the groove 692 are both greater than those of the pole piece 2, so that a single pole piece 2 can fall on the cover plate 693, and all information of the pole piece 2 can be collected.

In an embodiment, the groove 692 is used to communicate with the vacuum-pumping device 661 through the vacuum-pumping joint 695, and the cover plate 693 is provided with a cover plate suction hole 696, so that when the vacuum-pumping device 661 works, the cover plate suction hole 696 generates a suction force on the pole piece 2. Similarly, the groove 692 may also be connected to a vacuum breaker assembly for providing gas to the surface of the pole piece 2 facing the second bottom plate 69 when the pole piece 2 is being transported to a material extraction operation.

It will be readily appreciated that the first 61 and second 66 mechanisms of the present pole piece conveyor 60 may be arranged to operate simultaneously, such that the first 62 and second 67 conveyors move simultaneously and stop simultaneously; accordingly, the first detecting member 613 and the image capturing device 665 can be operated cooperatively, so that the efficiency can be improved.

In the pole piece conveying device provided by the application, a first mechanism and a second mechanism are arranged, the second mechanism is used for picking up the pole piece from the first mechanism, and at least one of the first mechanism and the second mechanism is arranged to move to expose the lower surface of the pole piece picked up by the second mechanism, so that the pole piece can be conveyed to a state convenient to carry. The pole piece conveying device can realize inverted conveying on the second mechanism, namely the upper surface of the pole piece is fixed by the second mechanism when the pole piece conveying device is arranged on the second mechanism, and the lower surface of the pole piece is exposed at the moment and is not adsorbed or fixed by the second mechanism, so that the exposed lower surface of the pole piece adsorbed by the conveying assembly from the lower part of the pole piece can be met, and the lower surface of the pole piece is quickly conveyed to the lower surface of the diaphragm, and the conveying efficiency of the pole piece can be improved.
