Description

Technical Field

[0001] The invention relates to the field of manufacturing cutting-type special-shaped pole piece button-type battery winding equipment, and in particular to a button-type swing-arm feeding mechanism. Background Art

[0002] Battery pole pieces are an important part of the battery, usually used in lithium-ion batteries and other types of batteries. They are the core components inside the battery, responsible for the storage and release of electrical energy. In the battery manufacturing process, handling equipment is usually required to transport the pole pieces. The existing handling and adsorption methods are mostly cylinder-connected suction cup adsorption, using the cylinder rotation angle and mechanical limit, and then using the screw to deliver the piece. During the delivery process, the front part is lifted by the suction cup, and the screw drives the suction cup mechanism. The rear end is not adsorbed and suspended, resulting in low cell accuracy during winding, pole piece powder loss, and pole piece deviation during traction.

[0003] In the prior art, for example, the patent with publication number CN212374404U discloses a swing-type material distributing robot arm, which includes a swing mechanism provided on a mounting seat, a rotating mechanism provided on the swing mechanism, and a suction cup assembly provided on the rotating mechanism, wherein the swing mechanism is used to control the left and right swing of the rotating mechanism, the rotating mechanism is used to control the rotation of the suction cup assembly, and the suction cup assembly is used to absorb the pole piece. However, although this technology has improved some of the original problems, there are still aspects that need to be further optimized to better meet the actual detection needs.

[0004] 1. Although the above-mentioned prior art can absorb the electrode piece through the suction cup, its suction cup can only absorb the ordinary electrode piece with a regular outer side and a rectangular shape, while the outer side of the special-shaped electrode piece is usually irregular, such as a circle, an ellipse or a polygon, and the above-mentioned suction cup is rectangular. Therefore, when the special-shaped electrode piece is absorbed, the end face of the special-shaped electrode piece cannot completely cover the adsorption end of the suction cup, resulting in the suction of the electrode piece to be unstable due to the leakage of the suction force of the suction cup when the electrode piece moves with the suction cup, so that part of the electrode piece is separated from the suction cup and finally causes the electrode piece to fall off.

[0005] 2. When the electrode is being transported and adsorbed, it is usually necessary to clean the dust on its surface to ensure that the surface of the electrode is clean. However, the above-mentioned prior art cannot clean the dust on the surface of the electrode, and cannot prevent dust from falling onto the surface of the electrode during adsorption and transportation. During the transportation process, when the above-mentioned suction cup adsorbs the electrode, the suction force of the suction cup directly adsorbs the electrode. If the height difference of some areas of the electrode is inconsistent, the electrode will shake when being adsorbed by the suction cup, causing the powder on the electrode to detach from the electrode when shaking.

[0006] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing electrode adsorption and transportation equipment. Summary of the invention

[0040] The following combination Figures 1 to 14 Embodiments of the present invention are described in detail.

[0041] The embodiment of the present application discloses a button-type swing arm feeding mechanism. It should be noted that this application is mainly applied in the process of transporting battery electrodes. In terms of technical effects, multiple suction cups can synchronously adsorb the end face of the electrode to prevent the electrode from tilting on one side during the transportation process. In particular, this application can be compatible with special-shaped electrodes and conventional electrodes. The cantilever-type electrode transportation is more stable than the traction-type transportation structure, with higher transportation efficiency, faster angle adjustment efficiency, better dust control without secondary contact with other mechanisms or electrodes, higher cleanliness, and higher precision.

[0042] Embodiment 1: Refer to Figure 1 and Figure 2 As shown, it includes a support plate 11, guide rails 12, a sliding plate 13, a swing mechanism 2, a U-shaped frame 20, a rotating shaft 21, a swing plate 22, an adsorption unit 3, and a swing motor 23. Guide rails 12 are symmetrically arranged on one side of the support plate 11. A sliding plate 13 with an L-shaped cross-section is slidably arranged between the guide rails 12. A swing mechanism 2 is arranged on one side of the sliding plate 13. The guide rails 12 are used to limit and guide the sliding plate 13. When the sliding plate 13 is driven by an external force, it can reciprocate under the limitation of the guide rails 12 and drive the swing mechanism 2 to move synchronously when moving, so as to change the orientation of the swing mechanism 2.

[0043] The swing mechanism 2 includes a U-shaped frame 20 with a U-shaped cross-section arranged on one side of the sliding plate 13. A rotating shaft 21 is rotatably arranged on the inner side wall of the U-shaped frame 20. A swing plate 22 is sleeved outside the rotating shaft 21. That is, the sliding plate 13 can drive the U-shaped frame 20 to move synchronously. When the rotating shaft 21 is driven by an external force, it can drive the swing plate 22 outside it to swing along its axis.

[0044] An adsorption unit 3 for adsorbing the electrode is arranged on the swing plate 22, and the swing mechanism 2 is used to drive the adsorption unit 3 to adjust the angle, so that the adsorption unit 3 can stably place the adsorbed electrode in the receiving device at any angle.

[0045] The swing mechanism 2 further includes a swing motor 23 arranged on one side of the U-shaped frame 20 through a motor seat. The main shaft of the swing motor 23 passes through the outer wall of the corresponding U-shaped frame 20 and is connected to one end of the rotating shaft 21. That is, the rotating shaft 21 can be driven to rotate synchronously by the swing motor 23.

[0046] Refer to Figure 4 、 Figure 5 and Figure 6As shown, the adsorption unit 3 is used for adsorbing the pole piece; specifically, the adsorption unit 3 includes a limit plate 30, a cross plate 31, a mounting groove 32, an adsorption component 4, an adjusting shaft 33, a rubbing plate 1 34 and a rubbing plate 2 35. The limit plate 30 is arranged on the inner wall of the swing plate 22, and a cross plate 31 is slidably penetrated on the limit plate 30. The cross plate 31 is provided with several mounting grooves 32 distributed along its extension section, and the adsorption component 4 for gas adsorption on the end of the pole piece is installed in the mounting groove 32, that is, the limit plate 30 can limit and guide the cross plate 31, so that the cross plate 31 can move in the up and down directions when driven by external force, and drive the adsorption component 4 to move synchronously during the movement. Therefore, it can be seen that when the adsorption component 4 corresponds to the pole piece, the cross plate 31 drives the adsorption component 4 to contact the pole piece, and then the pole piece is adsorbed on the adsorption component 4.

[0047] A plurality of adjusting shafts 33 are rotatably provided on one side of the transverse plate 31, and a rubbing plate 1 34 and a rubbing plate 2 35 are slidably penetrated between the adjusting shafts 33. The rubbing plate 1 34 and the rubbing plate 2 35 are also provided with mounting grooves 32 for mounting the adsorption component 4, that is, the adjusting shaft 33 can support and limit the rubbing plate 1 34 and the rubbing plate 2 35. In actual use, when facing pole pieces of different sizes and irregular shapes, the adsorption component 4 is installed in the corresponding mounting groove 32 according to actual needs, and then the rubbing plate 1 34 and the rubbing plate 2 35 are driven to slide on the adjusting shaft 33 for precise adjustment, so that multiple adsorption components 4 can accurately adsorb the left and right positions, front and back positions and the center positions of the pole pieces to prevent the pole pieces from tilting due to some areas not being adsorbed during transportation.

[0048] Continue to refer to Figure 5 As shown, the adsorption assembly 4 is used for adsorbing gas on the surface of the electrode; specifically, the adsorption assembly 4 includes a main cylinder 40, a fixing bolt 41, a telescopic sleeve 42 and a suction cup 43, several main cylinders 40 are respectively located in the corresponding mounting grooves 32, and the outer side of the main cylinder 40 is symmetrically threaded with fixing bolts 41, and the two fixing bolts 41 are respectively tightly attached to the upper and lower sides of the corresponding cross plate 31, extension plate 1 34 and extension plate 2 35, that is, the main cylinder 40 is fixed in the mounting groove 32 by the fixing bolts 41. When disassembling, the fixing bolts 41 are screwed by the handle. At this time, the fixing bolts 41 move on the outer wall of the main cylinder 40 and are no longer tightly attached to the upper and lower sides of the cross plate 31, extension plate 1 34 and extension plate 2 35 until they are unscrewed from the main cylinder 40. At this time, the main cylinder 40 can be taken out from the mounting groove 32.

[0049] A telescopic sleeve 42 is provided at the lower end of the main cylinder 40, and a suction cup 43 is provided at the lower end of the telescopic sleeve 42. In actual use, it is connected to the air port on the outside of the main cylinder 40 through an external cylinder. At this time, when the telescopic sleeve 42 drives the suction cup 43 to contact the outside of the pole piece, the external cylinder evacuates air through the main cylinder 40, the telescopic sleeve 42 and the suction cup 43, and the end face of the pole piece is adsorbed on the suction cup 43, so that the horizontal plate 31, the extension plate 1 34 and the extension plate 2 35 can indirectly carry the pole piece.

[0050] It should be noted that the telescopic sleeve 42 is a telescopic structure with a push spring installed inside. After the corresponding suction cup 43 has contacted the end face of the pole piece, if some suction cups 43 have not contacted the end face of the pole piece due to accuracy and other reasons, the horizontal plate 31, the extension plate 1 34 and the opposite extension plate 2 35 will continue to drive all the suction cups 43 to descend, so that the remaining suction cups 43 can all contact the surface of the pole piece. At this time, the telescopic end of some telescopic sleeves 42 will shrink, so that the horizontal plate 31, the extension plate 1 34 and the opposite extension plate 2 35 can continue to descend, and then the corresponding suction cups 43 can be driven to rise by the horizontal plate 31, the extension plate 1 34 and the opposite extension plate 2 35 to drive the pole piece to be transported.

[0051] Continue to refer to Figure 6 As shown, an adjustment component 5 for adjusting and limiting the spacing between extension plate 1 34 and extension plate 2 35 is provided on the adjustment shaft 33; specifically, the adjustment component 5 includes a thread groove 1 50, a thread groove 2 51 and a friction plate 52, and the thread groove 1 50 and the thread groove 2 51 are respectively arranged on the outer sides of the two adjustment shafts 33, and the extension plate 1 34 and the extension plate 2 35 are respectively threadedly connected with the thread groove 1 50 and the thread groove 2 51, that is, the extension plate 1 34 is threadedly connected with the thread groove 1 50, and the extension plate 2 35 is slidingly connected with the thread groove 1 50.

[0052] The second extension plate 35 is threadedly connected to the second thread groove 51 , and the first extension plate 34 is slidably connected to the second thread groove 51 .

[0053] During use, external force drives the adjustment shaft 33 with a thread groove 50 on the outside to rotate, which will drive the extension plate 1 34 to move in the front and rear directions under the limiting guidance of the other adjustment shafts 33. Similarly, the adjustment shaft 33 with a thread groove 51 on the outside is driven to rotate, so that the extension plate 2 35 can also move independently. The distance between the extension plates 1 34 and 35 can be precisely adjusted to adapt to pole pieces of different specifications.

[0054] A friction plate 52 is provided on the side of the two adjustment shafts 33 away from the extension plate 2 35, and the two friction plates 52 correspond to the thread groove 1 50 and the thread groove 2 51 respectively, that is, by holding the friction plate 52 by hand, the corresponding adjustment shaft 33 can be driven to rotate through the friction plate 52.

[0055] Continue to refer to Figure 2 and Figure 3 As shown, a transverse movement component 6 for driving the adsorption unit 3 to move laterally is provided on the support plate 11; specifically, the transverse movement component 6 includes a transverse movement screw 60 and a transverse movement motor 61, the transverse movement screw 60 is rotatably arranged on one side of the support plate 11, and one side of the transverse movement screw 60 passes through the sliding plate 13 and is threadedly connected thereto, that is, when the transverse movement screw 60 rotates, the sliding plate 13 can be driven to move along the extension section of the guide rail 12, thereby indirectly driving the pole piece adsorbed by the adsorption component 4 to move laterally.

[0056] A transverse motor 61 is arranged on one side of the support plate 11 through a motor seat. The main shaft of the transverse motor 61 passes through the outer wall of the support plate 11 and is connected to the outer side of the transverse screw rod 60 through a belt drive. The transverse motor 61 drives the transverse screw rod 60 to rotate through the belt drive.

[0057] Example 2: Reference Figure 7 , Figure 8 and Fig. 9 As shown, on the basis of the first and second embodiments, in order to clean the dust on the pole piece before transportation, an extension plate 70 is symmetrically arranged on the swing plate 22, and a connecting plate 71 is slidably arranged between the extension plates 70, and an ultrasonic cleaning unit 7 for cleaning the dust on the pole piece is arranged on the connecting plate 71; specifically, the ultrasonic cleaning unit 7 includes an extension plate 70, a connecting plate 71, a cleaning screw 72, a circular plate 73, an arc frame plate 74, an ultrasonic dust removal device 75, an extension rod 76, a contact plate 77 and an avoidance groove 78, the cleaning screw 72 is rotatably penetrated on the connecting plate 71, the outer side of the cleaning screw 72 is threadedly connected with the circular plate 73, the lower side of the connecting plate 71 is provided with an arc frame plate 74, and one side of the circular plate 73 extends to the inner side of the arc frame plate 74 to slide with it in a keyway, that is, when the cleaning screw 72 is driven by an external force to rotate, the circular plate 73 can be driven to move in the up and down directions under the limit guide of the arc frame plate 74.

[0058] An ultrasonic dust removal device 75 is arranged on the outer side of the circular plate 73, and an extension rod 76 is arranged at the lower end of the ultrasonic dust removal device 75. A contact plate 77 is arranged at the end of the extension rod 76. An avoidance groove 78 for avoiding the cleaning screw 72 is opened on the contact plate 77. The circular plate 73 can drive the ultrasonic dust removal device 75 to move synchronously. The ultrasonic dust removal device 75 drives the contact plate 77 to move synchronously through the extension rod 76. The avoidance groove 78 is used to prevent the cleaning screw 72 from colliding with the contact plate 77. When the contact plate 77 contacts the end of the pole piece, the mechanical vibration generated by the ultrasonic transducer is transmitted to the surface of the pole piece through the contact plate 77. The high-frequency vibration will destroy the adhesion between the dust particles and the pole piece, causing them to fall off the surface of the pole piece. Then the external cylinder transmits gas toward the main cylinder 40, and the gas blows away the dust.

[0059] That is, during use, the cleaning screw 72 is first used to indirectly drive the contact plate 77 to move downward, so that the contact plate 77 contacts the surface of the pole piece, so that the dust on the pole piece is vibrated and thus detaches from the pole piece, and then the suction cup 43 is used to blow air to make the dust leave the surface of the pole piece. After cleaning, the cleaning screw 72 indirectly drives the contact plate 77 to retract, and at this time, the horizontal plate 31, the extension plate 1 34 and the extension plate 2 35 indirectly drive the adsorption component 4 to adsorb and transport the pole piece.

[0060] It should be noted that the "ultrasonic dust removal device 75" in the above implementation process is an existing device, and its role in this application is to generate mechanical vibration to make the dust on the surface of the pole piece fall off, so it will not be described in detail.

[0061] Example 3: Reference Figure 7 and Fig.10 As shown, on the basis of Example 2, in order to drive the adsorption unit 3 and the ultrasonic cleaning unit 7 to move in the up and down directions, a driving unit 8 is arranged on the connecting plate 71; specifically, the driving unit 8 includes a lifting screw 80, an L-shaped plate 81, a ratchet tooth 82 and a driving shaft 83, the lifting screw 80 is rotatably arranged on one side of the connecting plate 71, and an L-shaped plate 81 is arranged on one side of the corresponding support plate 2, and the end of the lifting screw 80 is threadedly connected to the L-shaped plate 81. When the lifting screw 80 is driven by an external force, the corresponding extension plate 2 35 can be driven to move in the up and down directions through the L-shaped plate 81, so that the cross plate 31 and the extension plate 1 34 are also moved synchronously, thereby enabling the adsorption component 4 to move.

[0062] And because the second extension plate 35 will move, when it moves, the L-shaped plate 81 will drive the connecting plate 71 to move synchronously on the extension plate 70 through the lifting screw rod 80.

[0063] The lifting screw 80 and the cleaning screw 72 are both sleeved with a ratchet tooth 82 on one side of the connecting plate 71, and the rotation driving directions of the two ratchet teeth 82 are opposite. A driving shaft 83 is rotatably arranged on the connecting plate 71, and the two ratchet teeth 82 are connected to the driving shaft 83 by belt transmission. The ratchet teeth 82 can drive the corresponding cleaning screw 72 and the lifting screw 80 to rotate, and the rotation directions of the cleaning screw 72 and the lifting screw 80 are opposite, and two spiral grooves are provided on the outer sides of the cleaning screw 72 and the lifting screw 80, that is, they can drive the corresponding circular plate 73 and the L-shaped plate 81 to reciprocate.

[0064] The driving shaft 83 is connected to the external driving motor, and the driving shaft 83 is driven to rotate the corresponding ratchet teeth 82 through the belt transmission. Due to the unidirectional driving characteristics of the ratchet teeth 82, the driving shaft 83 can only drive the cleaning screw 72 or the lifting screw 80 to rotate when it moves in one direction. It can be seen that by controlling the rotation direction of the driving shaft 83, the cleaning screw 72 or the lifting screw 80 can be driven to rotate alone.

[0065] Embodiment 4: Based on Embodiment 1, Embodiment 2 and Embodiment 3, refer to Fig.11 and Fig.12 As shown, before the pole piece is adsorbed, its surface may bend, and the suction port of the suction cup 43 is in a vertical plane. Therefore, when the suction cup 43 adsorbs the pole piece, there is an angle difference between the suction port of the suction cup 43 and the surface of the pole piece, resulting in the suction cup 43 being unable to completely adhere to the surface of the pole piece and unable to fully adsorb the pole piece, causing the pole piece to fall off. Therefore, under the above viewpoint, a swing component is provided between the suction cup 43 and the telescopic sleeve 42. Specifically, the swing component includes a swing ball 9 and a through groove 90. The swing ball 9 is arranged between the suction cup 43 and the corresponding telescopic sleeve 42, and the swing ball 9 is rotatably connected to the telescopic sleeve 42. The swing ball 9 is provided with a through groove 90 on both sides which are respectively connected with the suction cup 43 and the inside of the telescopic sleeve 42.

[0066] That is, the gas can be extracted by the external cylinder through the suction cup 43, the through groove 90 and the telescopic sleeve 42. Therefore, when the suction cup 43 falls to adsorb the pole piece, if the corresponding pole piece area is bent, the swinging ball 9 is driven by the external force to drive the suction cup 43 to swing along its axis, so that the end of the suction cup 43 swings to correspond to the inclined surface of the pole piece. At this time, the end of the suction cup 43 can be fully in contact with the outside of the pole piece, thereby adsorbing the pole piece.

[0067] When the suction cup 43 sucks the stacked electrode sheets, if multiple electrode sheets are bonded together, the suction cup 43 will suck up multiple electrode sheets at one time. Therefore, the suction cup 43 first sucks horizontally and then swings to make the bonded electrode sheets fall, thereby achieving the suction of a single electrode sheet.

[0068] Reference Fig.13 As shown, a swing unit for driving the swing ball 9 to swing is also provided on the telescopic sleeve 42. Specifically, the swing unit includes a driven shaft 91, a linkage shaft 92, a spring rod 93, a rectangular plate 94 and a push spring rod 95. The driven shaft 91 is rotatably passed through one side of the telescopic sleeve 42, and one end of the driven shaft 91 is connected to the swing ball 9. That is, when the swing ball 9 is driven by an external force, it can drive the swing ball 9 to rotate, thereby realizing the swinging effect of the suction cup 43.

[0069] A linkage shaft 92 is rotatably inserted at the fixed end of the upper end of the telescopic sleeve 42, and a spring rod 93 is commonly arranged between the two corresponding linkage shafts 92 in the horizontal direction. The horizontal direction refers to the linkage shaft 92 on the telescopic sleeve 42 corresponding to the horizontal plate 31, the extension plate 1 34 and the extension plate 2 35. The linkage shaft 92 is synchronously rotated through the spring rod 93. Furthermore, the spring rod 93 will adaptively retract and retract when the spacing between the horizontal plate 31, the extension plate 1 34 and the extension plate 2 35 changes, so as to avoid interference in the spacing adjustment between the horizontal plate 31, the extension plate 1 34 and the extension plate 2 35.

[0070] A rectangular plate 94 is provided on the outer side of the sliding end of the telescopic sleeve 42, and a push spring rod 95 is rotatably penetrated on the rectangular plate 94. The fixed end of the push spring rod 95 is rotatably connected to the rectangular plate 94. One side of the fixed end of the push spring rod 95 extends to the upper end of the corresponding driven shaft 91 and is connected to the driven shaft 91 through a bevel gear transmission. The telescopic end of the push spring rod 95 extends to the lower side of the linkage shaft 92 and is connected to the linkage shaft 92 through a bevel gear transmission.

[0071] As can be seen from the above, the linkage shaft 92 on one side can be driven to rotate by external force, and when rotating, it drives the push spring rod 95 to rotate synchronously through the bevel gear transmission. The push spring rod 95 can drive the driven shaft 91 to rotate through the bevel gear transmission, so that the driven shaft 91 can drive the swinging ball 9 to swing.

[0072] When the suction cup 43 is adsorbed, the telescopic ends of the telescopic sleeves 42 will be telescoped, so the telescopic end of the push spring rod 95 will be telescoped synchronously with the telescopic sleeve 42, and the corresponding bevel gear will be pushed by its telescopic end to always mesh with the bevel gear on the outside of the linkage shaft 92. Therefore, when the spacing between the cross plate 31, the extension plate 1 34 and the extension plate 2 35 is adjusted, the linkage shaft 92 can still rotate together through the adaptive telescopic extension of the spring rod 93. When the height of the fixed end of the telescopic sleeve 42 moves up and down, the push spring rod 95 can be telescoped synchronously so that the linkage shaft 92 can always drive the driven shaft 91 to rotate through the push spring rod 95.

[0073] Reference Fig.14As shown, an annular plate 96 is provided on the inner wall of the telescopic end of the telescopic sleeve 42, and a reset push spring 97 is provided between the annular plate 96 and the fixed end of the telescopic sleeve 42. After the telescopic end of the telescopic sleeve 42 drives the suction cup 43 to contact the pole piece, if the fixed end continues to descend, the telescopic sleeve 42 slides to store the fixed end therein, and drives the reset push spring 97 to contract. When the fixed end moves upward, the reset push spring 97 pushes the fixed end to slide to the initial position. When all the fixed ends slide to the initial position, the suction cup 43 is driven to swing to be perpendicular to the telescopic sleeve 42 through the swinging ball 9. At this time, the pole piece is fully unfolded, so that the pole piece is flat when it is subsequently placed in the placement area without bending.

[0074] During operation: the first step is to fix the main tube 40 in the corresponding mounting groove 32 by means of the fixing bolts 41 according to the actual size of the pole piece, and then adjust the spacing between the cross plate 31, the extension plate 1 34 and the extension plate 2 35 by means of the adjusting component 5, so that the adsorption component 4 can more accurately adsorb the surface of the pole piece, and can also adsorb and transport the special-shaped pole piece.

[0075] Step 2: Then, the lateral motor 61 in the lateral assembly 6 indirectly drives the swing mechanism 2 and the adsorption unit 3 to move in the lateral direction, so that the adsorption unit 3 can correspond to the upper end of the pole piece. At this time, the driving unit 8 drives the ultrasonic cleaning unit 7 to clean the dust on the pole piece.

[0076] Step 3: After the dust on the pole piece is cleaned off, the driving unit 8 drives the ultrasonic cleaning unit 7 to retract, and then the driving unit 8 drives the adsorption unit 3 to descend. The adsorption unit 3 adsorbs the pole piece through the adsorption component 4, and during the adsorption process, the telescopic sleeve 42 can be adaptively extended and retracted, so that all the suction cups 43 can be attached to the surface of the pole piece.

[0077] Step 4: indirectly drive the swing mechanism 2 and the adsorption unit 3 to move to the discharge position through the transverse movement component 6. At this time, the adsorption unit 3 drives the swing plate 22 to swing along its axis, so that the inclination of the adsorption unit 3 corresponds to the angle of the discharge position, and then the adsorption component 4 can place the electrode on a placement position with a certain inclination, further improving the applicability of the present invention.

[0078] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0079] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
