Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing, and in particular to a robotic arm feeding mechanism. Background Technology

[0002] To keep pace with the current trend of intelligent and automated industrial development, robotic arms are now widely used for feeding steel sheets in the steel furniture production process, particularly in the bending process. The general process is as follows: the robotic arm picks up the sheet material from the stack, places it on a positioning plate for secondary positioning, and then feeds it into the automatic bending machine for bending.

[0003] For example, patent document CN222037732U discloses a robotic arm loading device with visual recognition, belonging to the field of loading device technology. It includes a robotic arm, a vision component, and a clamping component. The vision component and the clamping component are installed on the robotic arm. The clamping component is used for clamping and loading. The vision component is used for visual recognition to determine whether the object is in the clamping position. After recognition, the clamping component works. The clamping cylinder drives the crossbar to move, which further drives the clamping parts to clamp the two sides of the object. Then it can be moved to the designated position. The structure is simple, the loading is accurate, and the clamping is stable.

[0004] In the existing technology, in order to ensure the accuracy of the board during feeding, a positioning plate is required to perform secondary positioning of the board. However, this method not only takes up a lot of space due to the positioning plate, but also slows down the feeding speed because it requires multiple gripping. Utility Model Content

[0005] The purpose of this invention is to provide a robotic arm feeding mechanism to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A robotic arm loading mechanism includes a loading robotic arm, a loading component on one side of the loading robotic arm, a lifting and tilting component on one side of the loading component, the lifting and tilting component including a lifting bracket, a lifting slider slidably connected to the lifting bracket, a lifting drive component on the lifting bracket, a tilting bracket rotatably connected to the front side of the lifting slider, a tilting drive component on one side of the lifting slider, a suction cup assembly on the tilting bracket, the suction cup assembly including a support plate, a suction cup bracket on the support plate, a plurality of vacuum suction cups installed at one end of the suction cup bracket, holes for the suction cup brackets to pass through the support plate, a right-angle positioning component rotatably connected to one side of the support plate, the right-angle positioning component including a deflection plate rotatably connected to the support plate, an L-shaped baffle fixedly connected to one side of the deflection plate, a plurality of evenly distributed ball bearings installed on the deflection plate, holes corresponding to the holes on the support plate, and a linkage deflection component on the support plate.

[0008] Preferably, the material loading assembly includes a slide rail with two material loading platforms mounted on it, on which stacked plates are supported.

[0009] Preferably, the lifting drive component includes a lifting motor fixedly connected to the top of the lifting bracket, a vertical screw rotatably connected to the lifting bracket, the output end of the lifting motor being fixedly connected to the vertical screw, and the vertical screw being threadedly connected to the tilting bracket.

[0010] Preferably, the flipping drive component includes a flipping gear fixedly connected to one end of the flipping bracket, a flipping rack slidably connected to one side of the lifting slider, the flipping rack meshing with the flipping gear, a guide plate fixedly connected to one side of the lifting bracket, the guide plate being provided with a smooth Z-shaped groove, and the other end of the flipping rack being slidably connected to the groove on the guide plate.

[0011] Preferably, the suction cup assembly further includes a gate-shaped bracket fixedly connected to the flipping bracket, and a cylinder is fixedly connected to the gate-shaped bracket, with the cylinder output end fixedly connected to the suction cup bracket.

[0012] Preferably, the linkage deflection component includes a driven bevel gear disposed on the other side of the support plate and fixedly connected to the deflection plate, a driving bevel gear meshing on one side of the driven bevel gear, the driving bevel gear being rotatably connected to the support plate, a linkage gear being fixedly connected on one side of the driving bevel gear, a linkage rack being fixedly connected to the suction cup bracket, the linkage rack being able to mesh with the linkage gear when the vacuum suction cup is located on the side of the support plate close to the portal frame bracket, and the deflection plate and the support plate being rotatably connected by a rotation damper.

[0013] The beneficial effects are as follows: before the robotic arm picks up the material, the lifting and flipping component drives the suction cup component to descend and adsorb the steel plate. Then, during the ascent, the suction cup component flips to the other side, at which point the adsorption of the steel plate is canceled. In this way, the right-angle positioning component can position the plate under the action of gravity. Thus, through the organic combination of loading and positioning functions, the space occupied is reduced while the loading efficiency is improved.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-9 As shown, a robotic arm loading mechanism includes a loading robotic arm 1. A loading component is provided on one side of the loading robotic arm 1, and a lifting and tilting component is provided on the other side of the loading component. The lifting and tilting component includes a lifting bracket 301, a lifting slider 304 slidably connected to the lifting bracket 301, a lifting drive component on the lifting bracket 301, a tilting bracket 305 rotatably connected to the front of the lifting slider 304, a tilting drive component on one side of the lifting slider 304, and a suction cup assembly on the tilting bracket 305. The suction cup assembly includes a support plate 401, on which a suction cup bracket 404 is mounted. Several vacuum suction cups 405 are mounted on one end of the suction cup bracket 404. The support plate 401 has holes through which the suction cup bracket 404 passes. A right-angle positioning assembly is rotatably connected to one side of the support plate 401. The right-angle positioning assembly includes a deflection plate 501 rotatably connected to the support plate 401. An L-shaped baffle 502 is bolted to one side of the deflection plate 501. Several evenly distributed ball bearings 505 are mounted on the deflection plate 501. 3. The deflection plate 501 has holes corresponding to the holes on the support plate 401. This allows the suction cup bracket 404 to pass through the support plate 401 and contact the plate with the deflection plate 501 when the platform is in the material-retrieving state. The support plate 401 is equipped with a linkage deflection component. During material retrieval, the lifting drive component drives the tilting bracket 305 to rise and fall. The tilting bracket 305 moves the suction cup assembly close to the steel plate on the loading platform 202 and adsorbs it. Subsequently, the lifting drive component drives the steel plate to rise. After rising to a certain position, it tilts. The drive assembly drives the flipping bracket 305 to rotate more than 180 degrees. Then the suction cup bracket 404 retracts inward, and the steel plate contacts the ball bearing 503. At this time, the vacuum suction cup 405 cancels the suction, and the suction cup bracket 404 continues to retract inward. Through the linkage deflection component, the deflection plate 501 is deflected at a certain angle. In this way, the steel plate adheres to the L-shaped baffle 502 under the action of gravity, thereby achieving the positioning of the steel plate. In this way, when the loading robot arm 1 picks up the material, it can avoid secondary positioning and directly adsorb the positioned steel plate.

[0031] The material loading assembly includes a slide rail 201, on which two material loading platforms 202 are mounted. Each material loading platform 202 is equipped with a power component for driving the material loading platform 202 to move along the slide rail 201. This component is prior art and will not be described in detail here. The material loading platform 202 carries stacked plates. When one material loading platform 202 is used for loading operation, the stack of steel plates can be placed on the other material loading platform 202.

[0032] The lifting drive component includes a lifting motor 302 bolted to the top of the lifting bracket 301, a vertical screw 303 rotatably connected to the lifting bracket 301 by a bearing, the output end of the lifting motor 302 being fixedly connected to the vertical screw 303, the vertical screw 303 being threadedly connected to the tilting bracket 305, the lifting motor 302 driving the vertical screw 303 to rotate, and the vertical screw 303 driving the lifting slider 304 to rise and fall along the lifting bracket 301 through a threaded connection.

[0033] The flipping drive component includes a flipping gear 306 fixedly connected to one end of the flipping bracket 305, a flipping rack 307 slidably connected to one side of the lifting slider 304, the flipping rack 307 meshing with the flipping gear 306, a guide plate 308 bolted to one side of the lifting bracket 301, the guide plate 308 having a smooth Z-shaped groove, the other end of the flipping rack 307 slidably connected to the groove on the guide plate 308, during the lifting and lowering of the flipping bracket 305, the flipping rack 307 moves with the groove on the guide plate 308, the flipping rack 307 drives the flipping gear 306 to rotate, the flipping gear 306 drives the flipping bracket 305 to rotate, so that after the lifting slider 304 moves to the upper end, the flipping bracket 305 flips to the other side, facilitating the loading robot arm 1 to pick up the steel plate.

[0034] The suction cup assembly also includes a gate-shaped bracket 402 fixedly connected to the flip bracket 305. A cylinder 403 is bolted to the gate-shaped bracket 402. The output end of the cylinder 403 is fixedly connected to the suction cup bracket 404. The cylinder 403 drives the suction cup bracket 404 to move. The suction cup bracket 404 passes through the holes on the support plate 401 and the deflection plate 501 to adsorb the steel plate.

[0035] The linkage deflection component includes a driven bevel gear 504 located on the other side of the support plate 401 and bolted to the deflection plate 501. A driving bevel gear 505 meshes with one side of the driven bevel gear 504. The driving bevel gear 505 is rotatably connected to the support plate 401 via a bearing seat. A linkage gear 506 is fixedly connected to one side of the driving bevel gear 505. A linkage rack 507 is fixedly connected to the suction cup bracket 404. The linkage rack 507 can mesh with the linkage gear 506 when the vacuum suction cup 405 is located on the side of the support plate 401 near the portal frame 402. The deflection plate 501 and the support plate 401 are rotatably connected via a rotation damper. When the right-angle positioning component and the suction cup component are in the platform material-picking state, the linkage... The moving rack 507 and the connecting gear 506 are not engaged. At this time, since the deflecting plate 501 and the support plate 401 are rotatably connected by a damper, they will not easily deflect during the flipping process. After the flipping bracket 305 rotates to the other side, the suction cup bracket 404 retracts inward. The suction cup bracket 404 drives the connecting rack 507 to move. After the vacuum suction cup 405 cancels its adsorption on the steel plate, the connecting rack 507 begins to engage with the connecting gear 506. The connecting rack 507 continues to move, driving the connecting gear 506 to rotate. The connecting gear 506 drives the driving bevel gear 505 to rotate. The driving bevel gear 505 drives the driven bevel gear 504 to rotate. The driven bevel gear 504 drives the deflecting plate 501 to deflect at a certain angle.

[0036] Working principle: During material handling, the lifting motor 302 drives the vertical screw 303 to rotate. The vertical screw 303 drives the lifting slider 304 to rise and fall along the lifting bracket 301 via a threaded connection. The tilting bracket 305 drives the suction cup assembly to approach the steel plate on the loading platform 202. The cylinder 403 drives the suction cup bracket 404 to move. The suction cup bracket 404 passes through the support plate 401 and the deflection plate 501 to adsorb the steel plate. Subsequently, the lifting drive assembly drives the steel plate to rise. During the lifting and lowering process of the tilting bracket 305, the tilting rack 307 moves with the slide groove on the guide plate 308. The tilting rack 307 drives the tilting gear 306 to rotate. The tilting gear 306 drives the tilting bracket 305 to rotate. Thus, after the lifting slider 304 moves to the upper end, the tilting drive assembly drives the tilting bracket 305 to rotate more than 180 degrees. Then, the suction cup bracket 404 retracts inward, and the steel plate... When the steel plate contacts the ball bearing 503, the vacuum suction cup 405 releases its grip, and the suction cup bracket 404 continues to retract inward. The suction cup bracket 404 drives the linkage rack 507 to move. After the vacuum suction cup 405 releases its grip on the steel plate, it moves to the side of the support plate 401 near the portal frame 402. The linkage rack 507 then begins to mesh with the linkage gear 506. The linkage rack 507 continues to move, driving the linkage gear 506 to rotate. The linkage gear 506 drives the active bevel gear 505 to rotate, which in turn drives the driven bevel gear 504 to rotate. The driven bevel gear 504 causes the deflection plate 501 to deflect at a certain angle. Thus, the steel plate adheres to the L-shaped baffle 502 under the action of gravity, thereby achieving the positioning of the steel plate. This avoids secondary positioning when the loading robot arm 1 picks up the material, allowing it to directly grip the positioned steel plate.
