Description

Technical Field

[0001] This invention relates to the field of automotive parts loading and unloading equipment technology, specifically to an automotive parts loading and unloading robotic workstation. Background Technology

[0002] In the process of automation and large-scale development in the automotive manufacturing industry, the loading and unloading of auto parts is a key component of the production process, and its operational efficiency and stability directly affect the capacity and product quality of the entire production line. To reduce the intensity of manual labor and minimize human error, robotic workstations are widely used in auto parts production to automate loading and unloading operations. These workstations typically include a frame, a conveyor for transporting parts, and a robotic arm module for gripping and transferring parts. Through the coordinated operation of these components, the parts are seamlessly connected from transport to the next processing step.

[0003] However, existing automotive parts loading and unloading robotic workstations still face many technical problems that need to be solved in practical applications. Taking the sorting process as an example, most existing conveying devices only have simple conveying functions and lack effective sorting mechanisms. During the conveying process, automotive parts are prone to stacking and disorderly arrangement, making it impossible to release individual parts in an orderly manner. This leads to problems such as multiple parts being grabbed or misalignment when the robotic arm is gripping, which not only affects the gripping efficiency and makes it difficult to adapt to the pace requirements of mass production of automotive parts, but may also cause damage to parts due to collisions or robotic arm misoperation, increasing production costs.

[0004] With the increasing variety of automotive parts and the continuous improvement of production cycles, the aforementioned shortcomings of existing robotic workstations have become increasingly prominent, making it difficult to meet the demands for efficient, precise, and stable automated material handling. Therefore, developing a robotic workstation for automotive parts handling that can solve core problems such as insufficient material sorting accuracy and poor material handling stability, while simultaneously improving operational reliability, has become an urgent need in the current automation upgrade process of the automotive manufacturing industry. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a robotic workstation for loading and unloading automotive parts, aiming to solve the technical problems of insufficient material sorting accuracy and poor material handling stability in existing robotic workstations for loading and unloading automotive parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A robotic workstation for loading and unloading automotive parts includes a frame, on which a conveying device for transporting automotive parts is mounted, and a robotic arm module is mounted above the conveying device; the conveying device is equipped with a material sorting module. The robotic arm module includes a robotic arm body and a material handling module installed at the end of the robotic arm; The material distribution module includes mounting bases fixed on both sides of the conveying device. The mounting bases are rotatably mounted with a first baffle plate and a second baffle plate that alternately block materials by rotating synchronously in opposite directions. Only one accessory is released at a time, which facilitates subsequent grabbing. The material handling module includes a material handling frame installed and fixed on the main body of the robot arm. The material handling frame is equipped with one or more pairs of gripping modules. The gripping module includes a gripping body and a gripping drive device. The working surface of the gripping body is also provided with a vacuum adsorption plate. The gripping is achieved through a dual mechanism of mechanical action and vacuum adsorption.

[0007] Preferably, the mounting base is rotatably mounted with a first rotating shaft and a second rotating shaft, and a first gear plate and a second gear plate that mesh with each other are respectively mounted on the first rotating shaft and the second rotating shaft. The first baffle plate and the second baffle plate are respectively mounted on the top of the first rotating shaft and the second rotating shaft. The first rotating shaft or the second rotating shaft is driven by a rotation drive device.

[0008] Preferably, the rotation drive device includes a telescopic device, and the input end of the first or second rotating shaft is provided with a rotating rod. One end of the telescopic device is hinged to the input end of the rotating rod, and the other end is hinged to the mounting column. In order to limit the telescopic device from swinging up and down randomly and to limit its degree of freedom, the telescopic device is also provided with a limit sleeve.

[0009] Preferably, the rotational speed ratio between the second gear and the first gear is 1:1 to 1.5:1.

[0010] Preferably, the first baffle and the second baffle are arranged sequentially according to the conveying direction of the conveying device. Both of them are L-shaped plates. The first baffle is also provided with a turning arm to avoid interference with the second baffle.

[0011] Preferably, the first baffle plate and the second baffle plate are provided with a baffle block on the baffle side of their ends, and the baffle block can be a rubber block.

[0012] Preferably, the material handling rack is provided with a fixed base connected to the end of the robot arm body, and the lower end of the gripping body is provided with a hook for hooking the corresponding and suitable automotive parts.

[0013] Preferably, the clamping body has an air passage communicating with the vacuum adsorption plate, and the other end of the air passage has an air source connector for connecting to a vacuum pump through a corresponding hose.

[0014] Preferably, the frame includes an upper frame and a lower frame, the conveying device is a conveyor belt, the conveyor belt is installed on the lower frame, and the main body of the robot is installed and fixed on the upper frame; The conveying device is provided with guide plates on both sides, and the guide plates also include auxiliary guide plates located at the location of the material distribution module and lower than the first baffle plate and the second baffle plate.

[0015] Preferably, the conveying device has a detection module below the robotic arm module, and the detection module includes a sensor and its mounting plate.

[0016] The present invention has at least the following beneficial effects: This invention, by setting a material distribution module on the conveying device and adopting an alternating material blocking structure in which the first and second material blocking plates rotate synchronously in opposite directions, combined with the division of labor design of the two plates arranged sequentially according to the conveying direction, can realize the orderly graded material blocking of automotive parts, ensuring that only one part is released at a time, and completely avoiding the problems of part stacking, multiple parts being grabbed, or misaligned grabbing.

[0017] This invention significantly improves the stability and reliability of material handling. Specifically, the material handling module employs a dual gripping mechanism of mechanical clamping and vacuum adsorption, overcoming the limitations of existing single gripping methods. Mechanical clamping provides stable holding force to prevent parts from slipping laterally, while the vacuum adsorption plate ensures that parts do not fall vertically through negative pressure adsorption. The combined effect of these two mechanisms effectively solves the problems of easy slippage and damage when handling thin-walled, irregularly shaped, or smooth-surfaced parts. Simultaneously, the hook at the lower end of the gripping body can be adapted to parts with hook grooves or protrusions, further enhancing gripping stability. Multiple sets of gripping modules arranged in pairs on the material handling rack can be flexibly adjusted according to part specifications, expanding the workstation's adaptability and improving the versatility and reliability of material handling operations.

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be further described in detail below with reference to the embodiments of the present invention.

[0021] Figures 1 to 7 A robotic workstation for loading and unloading automotive parts is presented. The workstation includes a frame, which serves as the mounting base for the entire workstation. Specifically, the frame includes an upper frame 300 and a lower frame 100. A conveyor device 200, using a conveyor belt mounted on the lower frame 100, is primarily used for continuous conveying of automotive parts. This conveys the automotive parts to be gripped from the infeed end to the corresponding gripping area of ​​the robotic arm module 400, providing a stable material supply for subsequent material handling operations. The robotic arm body is mounted and fixed on the upper frame 300. The height of the upper frame 300 is adapted to the working stroke of the robotic arm body, ensuring that the robotic arm module 400 can accurately cover the gripping area of ​​the conveyor belt, achieving efficient gripping and transfer of parts.

[0022] To prevent the automotive parts from shifting during the conveying process and to ensure that the parts are accurately delivered to the material distribution module 500 and the gripping area, guide plates 210 are provided on both sides of the conveying device 200. The guide plates 210 extend along the conveying direction of the conveyor belt, and their spacing is adapted to the width of the automotive parts to be conveyed. They can guide and limit the parts during the conveying process, preventing the parts from slipping off the sides of the conveyor belt or shifting laterally.

[0023] Meanwhile, the guide plate 210 also includes an auxiliary guide plate 211 located at the position of the material distribution module 500 and lower in height than the first baffle plate 520 and the second baffle plate 530. The setting of the auxiliary guide plate 211 will not affect the material blocking operation of the material distribution module 500, and can also provide auxiliary guidance for the parts during the material distribution process.

[0024] To address the issue that the existing conveyor device 200 cannot achieve orderly release of individual parts, a material distribution module 500 is installed on the conveyor device 200. The core function of this material distribution module 500 is to orderly distribute the automotive parts continuously conveyed on the conveyor belt, releasing only one part at a time. This ensures that the robotic arm module 400 can accurately grasp a single part, avoiding problems such as grasping multiple parts or misalignment. At the same time, it ensures the synchronization of material distribution and grasping operations, adapting to the batch production cycle.

[0025] The material distribution module 500 includes mounting bases 510 fixed on both sides of the conveying device 200. The mounting bases 510 are connected to the frame of the conveying device 200 by bolts, which is firm and easy to disassemble and maintain, providing a stable mounting carrier for other components of the material distribution module 500. A first baffle plate 520 and a second baffle plate 530 are rotatably mounted on the mounting bases 510. The two baffle plates alternately block material by rotating synchronously in opposite directions. The working principle is that the two baffle plates alternately enter the blocking state and the release state through structural cooperation, thereby realizing the orderly release of individual parts and facilitating subsequent gripping by the robotic arm.

[0026] The first gear plate 522 and the second gear plate 532 mesh with each other, and their rotational speed ratio is determined by the ratio of their number of teeth. To achieve synchronous and opposite rotation of the first baffle plate 520 and the second baffle plate 530 with completely consistent action rhythm, it is necessary to ensure that the number of teeth of the first gear plate 522 and the second gear plate 532 are equal, so that their rotational speed ratio is 1:1. The rotation angle and rotational speed of the first baffle plate 520 and the second baffle plate 530 are completely synchronized. When one baffle plate rotates to the release state, the other rotates to the blocking state. There will be no action delay or advance, which effectively avoids interference between the two baffle plates. At the same time, it accurately achieves the material distribution requirement of releasing only one part at a time, ensuring that the material distribution rhythm is matched with the robot's gripping rhythm and the conveyor belt's conveying speed, further improving the accuracy and continuity of material distribution, and ensuring the operational stability of the entire workstation.

[0027] Of course, it should be noted that the rotational speed ratio between the first gear plate 522 and the second gear plate 532 does not necessarily have to be 1:1. They only need to meet the core requirement of synchronous reverse rotation; their movement rhythms do not need to be completely identical. The rotational speed of the second baffle plate 530 can be set to relatively fast, with the speed difference controlled within a reasonable range, ensuring no interference and not affecting the release of a single part at a time. Since the first baffle plate 520 is located upstream, its core function is to initially block the conveyed parts. After the detection module 220 confirms that a single part is in place and meets the gripping conditions, it slowly rotates to the release state. A slightly slower rotational speed is acceptable. To ensure more stable blocking of parts and prevent parts from shifting or slipping due to excessive rotation, while allowing sufficient positioning time for the robotic arm to grasp them; the second baffle 530 is located downstream, adjacent to the grasping area. Its core function is to block subsequent parts and prevent multiple parts from entering the grasping area at the same time. Its rotation speed is set relatively fast, so that after the first baffle 520 releases a single part, it can quickly rotate to the blocking state to block subsequent parts in time, preventing parts from piling up or misaligning. At the same time, after the robotic arm has finished grasping, it can quickly reset and release the next part, adapting to the continuous conveying rhythm of the conveyor belt and the grasping rhythm of the robotic arm.

[0028] Therefore, the design of the second baffle plate 530 rotating at a faster speed and the first baffle plate 520 rotating at a slightly slower speed not only meets the basic requirement of synchronous reverse rotation, but also adapts to the functional division of the two through differentiated rhythms. This not only accurately achieves the core requirement of releasing only one part at a time, but also reduces the redundant time of the material distribution action, improves the material distribution efficiency, and ensures the stability of material blocking and release. Typically, the speed of the second baffle plate 530 can be 1.2 to 1.5 times that of the first baffle plate 520. In this embodiment, the speed of the second baffle plate 530 is 1.2 times that of the first baffle plate 520.

[0029] To achieve synchronous counter-rotation of the first baffle plate 520 and the second baffle plate 530, a first rotating shaft 521 and a second rotating shaft 531 are rotatably mounted on the mounting base 510. The first rotating shaft 521 and the second rotating shaft 531 are parallel to each other and perpendicular to the conveying direction of the conveyor belt. They are connected to the mounting base 510 by bearings to ensure smooth rotation and minimal wear. A first geared disc 522 and a second geared disc 532 are respectively mounted on the first rotating shaft 521 and the second rotating shaft 531, respectively, and the meshing of the geared discs enables the first rotating shaft 521 and the second rotating shaft 531 to rotate synchronously in opposite directions. The first baffle plate 520 and the second baffle plate 530 rotate in the opposite direction, thereby driving them to move synchronously in the opposite direction, ensuring the coordination of the material blocking and releasing actions. The first baffle plate 520 and the second baffle plate 530 are respectively installed on the top of the first rotating shaft 521 and the second rotating shaft 531, and rotate synchronously with the rotation of the shaft to realize the switching between material blocking and releasing. The first rotating shaft 521 or the second rotating shaft 531 is driven by a rotation drive device, which provides power for the rotation of the shaft, thereby controlling the movement rhythm of the baffle plate to match the conveying speed of the conveyor belt and the grasping rhythm of the robot arm.

[0030] The rotation drive device is generally a motor that supports forward and reverse rotation. However, since the strokes for both forward and reverse rotation are small, frequent forward and reverse rotation can cause significant damage and affect its service life. In this embodiment, the following structure is selected: Specifically, it includes a telescopic device 550. The telescopic device 550 can use existing telescopic components such as cylinders or electric push rods, which have the advantages of rapid action, precise control, and simple structure, and can meet the needs of rapid switching of the baffle plate. The input end of the first rotating shaft 521 or the second rotating shaft 531 is provided with a rotating rod 524. The rotating rod 524 is vertically fixedly connected to the rotating shaft to form a lever structure, which facilitates the conversion of the linear motion of the telescopic device 550 into the rotational motion of the rotating shaft. One end of the telescopic device 550 is hinged to the input end of the rotating rod 524, and the other end is hinged to the mounting column 540. The mounting column 540 is fixed on the frame of the conveying device 200 to provide stable support for the telescopic device 550. This hinged connection method can adapt to the angle changes during the telescopic device 550's extension and retraction process, ensuring smooth power transmission.

[0031] Meanwhile, in order to limit the up-and-down swing of the telescopic device 550 and restrict its degree of freedom, and to prevent the shaft from shifting due to the swing of the telescopic device 550, thereby affecting the material stopping accuracy, the telescopic device 550 is also equipped with a limit sleeve 551. The limit sleeve 551 is fitted on the outside of the telescopic device 550 and is fixedly connected to the mounting column 540 or the mounting base 510. It can limit the movement trajectory of the telescopic device 550 and ensure the stability and accuracy of the telescopic action.

[0032] Specifically, the first baffle plate 520 and the second baffle plate 530 are arranged sequentially according to the conveying direction of the conveying device 200. This arrangement enables graded baffle of the parts, ensuring the orderly distribution of materials. Both baffle plates are L-shaped, which increases the contact area with the parts, improves the stability of the baffle, and prevents the parts from slipping during the baffle process. At the same time, the first baffle plate 520 is also equipped with a turning arm 523. The turning arm 523 can change the extension direction of the first baffle plate 520 to avoid interference with the second baffle during rotation, ensuring that the two baffle plates can smoothly complete the alternating baffle action without affecting the continuity of the distribution operation due to structural interference.

[0033] In addition, the first baffle plate 520 and the second baffle plate 530 are provided with a baffle block 525 on the baffle side at the end. The baffle block 525 can be a rubber block. The rubber material has a certain elasticity and cushioning performance, which can make flexible contact with the automotive parts during the baffle process, avoid scratches and deformation of the parts surface due to rigid collision, and increase the friction between the parts and the parts, further improving the stability of the baffle and preventing the parts from sliding during the baffle process.

[0034] The robotic arm module 400, as the core gripping component of the entire workstation, is used to grasp, transfer, and load / unload automotive parts. It includes the robotic arm body and the material handling module installed at the end of the robotic arm. The robotic arm body can adopt an existing multi-degree-of-freedom robotic arm, which can realize multi-directional movement such as up and down, left and right, forward and backward, and rotation. The gripping angle and transfer path can be adjusted according to actual operation requirements to adapt to the loading and unloading needs of different positions. The material handling module is installed at the end of the robotic arm body and moves synchronously with the robotic arm body. It is used to directly contact the automotive parts and realize gripping. Its structural design directly determines the stability and reliability of gripping.

[0035] The material handling module includes a material handling frame 410 mounted and fixed to the main body of the robotic arm. The material handling frame 410 adopts a rigid structure design, which can provide stable installation support for the gripping module 420. At the same time, the installation position and number of gripping modules 420 can be adjusted according to the specifications of the automotive parts and the gripping requirements. One or more pairs of gripping modules 420 are installed on the material handling frame 410. The pairs of gripping modules 420 can exert force simultaneously from both sides or both ends of the part, ensuring that the part is subjected to uniform force during gripping and avoiding gripping deviation or slippage. The multiple gripping modules 420 can be adapted to automotive parts of different sizes and shapes, improving the versatility of the workstation. The gripping module 420 includes a gripping body 422 and a gripping drive device 421. The gripping drive device 421 can be a cylinder or a motor to drive the gripping body 422 to achieve opening and closing actions, thereby realizing the gripping and releasing of parts. The power output of the gripping drive device 421 is stable and can accurately control the opening and closing range and clamping force of the gripping body 422, adapting to automotive parts of different materials and thicknesses.

[0036] To further improve the stability of gripping and avoid the limitations of a single gripping method, the working surface of the gripping body 422 is also equipped with a vacuum adsorption plate 423. The gripping is achieved through a dual mechanism of mechanical gripping and vacuum adsorption. This dual gripping method can complement the shortcomings of a single gripping method: mechanical gripping can provide a stable gripping force to ensure that the parts will not slip laterally during the transfer process; the vacuum adsorption plate 423 can tightly adsorb the parts onto the working surface of the gripping body 422 through vacuum negative pressure, preventing the parts from falling off in the vertical direction. It is especially suitable for thin-walled, irregularly shaped or smooth-surfaced automotive parts, effectively improving the stability and reliability of gripping and reducing the risk of parts falling or being damaged.

[0037] To accommodate automotive parts with specific structures, the gripping body 422 has a hook 4221 at its lower end. The shape of the hook 4221 matches the fitting part of the automotive part to be gripped, thus hooking the corresponding fitting part and further enhancing the gripping stability, preventing the part from slipping during high-speed transfer. This is especially suitable for automotive parts with hook grooves or protruding structures, expanding the workstation's compatibility range. Simultaneously, the gripping body 422 has an air passage 4231 communicating with the vacuum adsorption plate 423. The other end of the air passage 4231 has an air source connector 4232, which connects to a vacuum pump via a corresponding hose. When the vacuum pump operates, it can extract air from the vacuum adsorption plate 423 through the air passage 4231, creating a vacuum negative pressure to adsorb the part. The air source connector 4232 facilitates the connection and disconnection of the hose, making future maintenance and repair easier.

[0038] To ensure that the robotic arm module 400 can accurately grasp parts and avoid empty grasps or misgrabs, the conveying device 200 is equipped with a detection module 220 below the robotic arm module 400. The detection module 220 includes a sensor 222 and its mounting plate 221. The mounting plate 221 is used to fix the sensor 222 on the frame of the conveying device 200 to ensure that the detection position of the sensor 222 is accurate. The sensor 222 can be a photoelectric sensor 222 or a proximity sensor 222, which can detect in real time whether there are automotive parts in the corresponding grasping area on the conveyor belt, and whether the position of the parts is accurate. When the sensor 222 detects that the part has reached the designated grasping position, it will send a signal to the control system. The control system controls the robotic arm module 400 to perform the grasping action, and at the same time controls the material distribution module 500 to stop releasing. After the robotic arm has finished grasping and transferring, the material distribution module 500 will release the next part, realizing the coordinated cooperation of detection, material distribution and grasping, and further improving the accuracy and automation level of the operation.

[0039] During operation, the automotive parts to be grabbed are conveyed from the feeding end via a conveyor belt. Guided by the guide plate 210, the parts move smoothly along the conveyor belt and gradually approach the distribution module 500. When the first part moves to the distribution module 500, the first baffle plate 520 is in the blocking state, preventing the part from moving forward, while the second baffle plate 530 is in the releasing state. At this time, the sensor 222 detects that the part has reached the designated position and sends a signal to the control system. The control system controls the rotation drive device to rotate the first rotating shaft 521. Through the meshing of the first gear plate 522 and the second gear plate 532, the second rotating shaft 531 is driven to rotate in the opposite direction, thereby causing the first baffle plate 520 to rotate to the releasing state and the second baffle plate 530 to rotate to the blocking state, blocking the subsequent parts from moving forward, thus realizing the release of a single part.

[0040] At the same time, the control system controls the movement of the main body of the robot arm, which drives the material handling module to move above the part. The clamping drive device 421 drives the clamping body 422 to open and close, mechanically clamping the part from both sides. At the same time, the vacuum pump works, and the vacuum adsorption plate 423 generates negative pressure through the air passage 4231, tightly adsorbing the part onto the clamping body 422, thus achieving dual gripping.

[0041] After the gripping is completed, the main body of the robot arm moves the material handling module and accessories to the designated loading and unloading position. The gripping drive device 421 drives the gripping main body 422 to release, the vacuum pump stops working, the vacuum adsorption is released, and the unloading or transfer of accessories is completed.

[0042] Subsequently, the control system controls the rotation drive device to reset, so that the first baffle 520 returns to the baffle state and the second baffle 530 returns to the release state, releasing the next part. The above process is repeated to realize continuous and automated loading and unloading of automotive parts.
