Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and in particular to a material handling component and transport equipment with positioning and correction functions. Background Technology

[0002] Accurate and stable handling of goods during transport is crucial for ensuring production quality and efficiency. Currently, common handling components with positioning and correction functions often employ external clamping or suction methods when gripping jigs containing goods. External clamping grips achieve gripping by clamping the outside of the jig. However, due to potential errors in the shape and size of the jig's outer surface, external clamping cannot guarantee accurate clamping every time, easily resulting in incomplete or misaligned clamping, causing the jig to fall during transport and damaging both the jig and the goods inside. Furthermore, external clamping may damage the outside of the jig during clamping, affecting its lifespan. Suction gripping uses suction cups to adhere to the jig, but this method requires a high degree of surface flatness and cleanliness. If the jig surface is dusty, oily, or uneven, the suction cups cannot firmly adhere to the jig, also easily causing it to fall off during transport.

[0003] Furthermore, existing material handling components lack an effective correction mechanism when gripping the jig. During cargo transfer, the jig's position may shift due to factors such as mechanical vibration and positioning errors. When gripping the jig according to the preset position, inaccurate gripping can easily occur, leading to gripping failure or affecting subsequent production processes. Utility Model Content

[0028] Reference Figure 1 , Figure 2 and Figure 3 A material handling component with positioning and correction function includes a telescopic mechanism 100 and a gripping mechanism 200 connected to the movable end of the telescopic mechanism 100. The telescopic mechanism 100 drives the gripping mechanism 200 to move to pick up and place fixtures.

[0029] The gripping mechanism 200 includes two gripper drivers 210 and two grippers 220. The two gripper drivers 210 drive the two grippers 220 to move back-to-back or relative to each other to internally clamp or release the fixture. Specifically, when gripping the fixture, the two gripper drivers 210 drive the two grippers 220 to move relative to each other, causing the grippers 220 to extend into the fixture. Then, they drive the two grippers 220 to move back-to-back, achieving internal clamping through the friction and supporting force between the grippers 220 and the inner wall of the fixture, ensuring the fixture is firmly gripped. When releasing the fixture, the two gripper drivers 210 drive the two grippers 220 to move relative to each other, reducing the pressure between the grippers 220 and the inner wall of the fixture, thereby releasing the fixture.

[0030] Understandably, by employing the internal clamping principle, the gripper 220 clamps from within the fixture, unaffected by the shape and size errors of the fixture's outer side. This allows for more accurate location of the clamping point, ensuring a secure clamping of the fixture each time. This avoids the problems of incomplete clamping or misalignment that often occur with external clamping, significantly improving the accuracy and stability of the gripping process. The internal clamping method does not damage the outer side of the fixture, effectively extending its service life compared to external clamping, ensuring its precision and performance, and reducing production costs. For fixtures of different shapes and sizes, as long as there is suitable internal space for the gripper 220 to extend and clamp, the material handling component with positioning and correction functions of this invention can achieve accurate gripping, demonstrating strong adaptability and versatility.

[0031] Furthermore, the two gripper drive units 210 can respectively drive the two grippers 220 to move in the same direction, so that the grippers 220 are aligned with the fixture. A sensor and a drive device can also be provided. The sensor is used to detect the positional deviation between the gripping mechanism 200 and the fixture, and transmits the detection signal to the control system. The control system controls the drive device to operate according to the received signal. The drive device drives the gripping mechanism 200 to adjust its position, ensuring that the gripping mechanism 200 is accurately aligned with the fixture, thereby improving the accuracy and success rate of gripping.

[0032] It is easy to understand that the sensors and drive unit can detect the positional deviation between the gripping mechanism 200 and the fixture in real time, and adjust the position of the gripping mechanism 200 in a timely manner, ensuring that the gripping mechanism 200 is accurately aligned with the fixture. This effectively solves the problem of inaccurate gripping caused by fixture position deviation, greatly improving the success rate of gripping and reducing failures and downtime in the production process. Accurate gripping ensures that the fixture is positioned correctly during transfer, providing a good foundation for subsequent production operations, ensuring the smoothness and stability of the entire production process, and improving production efficiency and product quality.

[0033] In some embodiments, the gripping mechanism includes a controller, a position detection element, and two gripper drivers 210. The position detection element is installed on the side of the telescopic mechanism 100 near the fixture, and can acquire the position information of the fixture and feed this information back to the controller. The two gripper drivers 210 are respectively connected to two grippers 220. When the position detection element detects a positional deviation between the gripping mechanism 200 and the fixture, the controller analyzes and processes the deviation according to a preset algorithm, and then outputs a control signal to the corresponding gripper driver 210. For example, if the left gripper 220 is detected to be slightly to the left, the controller controls the left gripper driver 210 to move the left gripper 220 to the right; if both grippers 220 are deviated, the controller controls the two gripper drivers 210 respectively to move the two grippers 220 independently until the gripping mechanism 200 is accurately aligned with the fixture. This implementation allows for independent and precise control of the two grippers 220. The position of the grippers 220 can be flexibly adjusted according to the actual position of the fixture, thereby making the gripping mechanism 200 more accurately aligned with the fixture. This improves the accuracy and reliability of material handling, and is especially suitable for situations where the fixture position deviation is complex.

[0034] In other embodiments, the gripping mechanism includes a controller, a position detection component, and a gripper drive 210. The gripping mechanism 200 is slidably connected to the movable end of the telescopic mechanism 100 via a slide rail. The position detection component is installed at the bottom of the telescopic mechanism 100, capable of capturing images of the fixture and obtaining the fixture's position information through image processing algorithms, which is then fed back to the controller. When a positional deviation between the gripping mechanism 200 and the fixture is detected, the controller calculates the distance and direction that the gripping mechanism 200 needs to move based on the deviation information, and then outputs a control signal to the gripper drive 210. The gripper drive 210 can convert the rotational motion into linear motion of the entire gripping mechanism 200 through a lead screw and nut pair or other linkage structure, driving the gripping mechanism 200 to move as a whole until the gripping mechanism 200 is accurately aligned with the fixture. This embodiment uses a single gripper drive 210 to move the entire gripping mechanism 200, resulting in a relatively simple structure, reducing the number of parts, lowering costs, and reducing maintenance difficulty. Simultaneously, the vision sensor can provide more comprehensive fixture position information, improving the accuracy and adaptability of the correction.

[0035] Optionally, in some embodiments, a single gripper drive 210 and a linkage are used. The gripper drive 210 can be an electric actuator 222, and the linkage can be a linkage mechanism. Specifically, the linkage consists of two connecting rods, one end of which is hinged to each of the two grippers 220, and the other end is hinged together to the output end of the electric actuator 222. When the output end of the electric actuator 222 extends, it pushes the linkage to move, causing the two connecting rods to move the two grippers 220 relative to each other, thus clamping the goods. When the output end of the electric actuator 222 retracts, it pulls the linkage to move, causing the two connecting rods to move the two grippers 220 away from each other, releasing the goods. Using a single gripper drive 210 and linkage reduces the number of drive components, lowering cost and energy consumption. Simultaneously, the linkage design improves the synchronization of the two grippers 220's movements, ensuring the goods are evenly clamped and supported, thus improving the stability and reliability of the gripping process.

[0036] In other embodiments, the two gripper drives 210 can be small cylinders. Each cylinder is bolted to the movable end of the telescopic mechanism 100, and the output end of each cylinder is connected to a gripper 220 via a connector. When gripping goods, the output ends of both cylinders extend simultaneously, pushing the two grippers 220 to move relative to each other, thus clamping the goods. When releasing goods, the output ends of both cylinders retract simultaneously, causing the two grippers 220 to move away from each other, releasing the goods. In this embodiment, the two grippers 220 are driven by independent drives, allowing for more precise control of the movement speed and force of each gripper 220, adapting to the gripping needs of goods of different shapes and sizes. Moreover, when one drive fails, the other drive can still partially operate, improving the system's reliability and fault tolerance.

[0037] Reference Figure 2 and Figure 3 In this embodiment, two gripper drive units 210 are provided, and the gripping mechanism is also equipped with a controller and a position detection unit. The position detection unit is installed on the telescopic mechanism 100 and can measure the distance and position deviation information between the gripping mechanism 200 and the fixture in real time, and feed this information back to the controller. The controller is directly connected to the two gripper drive units 210 through a circuit. When a position deviation is detected, the controller calculates the distance and direction that each gripper 220 needs to move based on the deviation, and then directly outputs a control signal to the corresponding gripper drive unit 210, controlling the two gripper drive units 210 to drive one or both grippers 220 to move, thereby correcting the deviation of the gripping mechanism 200 and making it accurately aligned with the fixture.

[0038] Understandably, by directly implementing the application through the gripper drive component 210, the need for an additional gripper drive component 210 is eliminated, significantly reducing the number of parts, simplifying the equipment structure, and lowering costs and equipment complexity. Simultaneously, directly controlling the gripper drive component 210 for correction results in faster response speeds and more timely adjustments to the position of the gripping mechanism 200, improving the efficiency and accuracy of material handling.

[0039] Specifically, the gripper drive unit 210 consists of two motors, with a linkage gear 211 connected to the output end of each motor via a key. The gripper 220 includes a driven rack 221, which meshes with the linkage gear 211. When the motors start, their output ends drive the linkage gear 211 to rotate. Since the linkage gear 211 meshes with the driven rack 221, according to the gear transmission principle, the rotation of the linkage gear 211 drives the driven rack 221 to move linearly, thereby moving the gripper 220. By controlling the forward and reverse rotation of the two motors, the two grippers 220 can move relative to each other or move in opposite directions, completing the gripping and releasing of goods.

[0040] The transmission system employs a motor, a linkage gear 211, and a driven rack 221, resulting in high transmission precision. This allows for accurate control of the gripper 220's movement distance and speed, ensuring the accuracy of cargo handling and placement. Furthermore, this compact transmission structure occupies little space, facilitating the miniaturization and integration of the equipment.

[0041] Furthermore, the gripper 220 also includes a push rod 222 connected to the driven rack 221 and a support rod 223 connected to the bottom of the push rod 222. The push rod 222 is made of high-strength, wear-resistant material, and its front end is designed to match the internal shape of the goods, used to abut against and internally support and clamp the goods. The support rod 223 has an L-shaped structure, with one end connected to the bottom of the push rod 222 and the other end extending downwards towards the goods. When the push rod 222 internally supports and clamps the goods, the support rod 223 can prevent the goods from falling off. For example, when gripping a fixture holding goods, the front end of the push rod 222 inserts into the fixture for internal support and clamping, while the support rod 223 supports the bottom of the fixture, ensuring that the fixture will not fall off during transfer. The design of the push rod 222 and the support rod 223 further improves the stability and reliability of the gripper 220 in gripping goods. The push rod 222 can accurately clamp the goods internally, ensuring that the goods will not loosen during the gripping process; the support rod 223 can prevent the goods from falling off due to unexpected situations during the transfer, reducing the damage to the goods and the occurrence of production accidents.

[0042] Reference Figure 1It should be noted that the movable end of the telescopic mechanism 100 is equipped with two gripping mechanisms 200. These two gripping mechanisms 200 are bolted to both sides of the movable end of the telescopic mechanism 100 and are arranged opposite to each other. During material handling, the two gripping mechanisms 200 can work simultaneously, gripping and placing different goods respectively, improving work efficiency. For example, on a production line, one gripping mechanism 200 can grab a fixture from the equipment in the previous process, while the other gripping mechanism 200 can simultaneously place the grabbed fixture onto the fixture in the next process. The two oppositely arranged gripping mechanisms 200 can achieve synchronous gripping and placement of goods, greatly shortening the material handling time and improving production efficiency. This is especially suitable for large-scale, continuous production scenarios, effectively reducing equipment idle time and improving equipment utilization.

[0043] In other embodiments, the movable end of the telescopic mechanism 100 is provided with three gripping mechanisms 200, which are fixed to the movable end of the telescopic mechanism 100 at equal and uniform intervals via connecting plates. In practical applications, the three gripping mechanisms 200 can be controlled simultaneously to perform gripping and placement operations on goods according to production needs. For example, in some production processes that require the simultaneous handling of multiple goods, the three gripping mechanisms 200 can grip goods at different positions or of different types, and then place them onto the corresponding fixtures at once. Setting up multiple gripping mechanisms 200 arranged at equal and uniform intervals can further improve the efficiency and flexibility of material handling. It can adapt to more complex production tasks, meet diverse production needs, reduce the number of equipment replacements and adjustments, and lower production costs.

[0044] Reference Figure 1 and Figure 3 The gripping mechanism is also equipped with four barcode readers 300, which are installed at the four corners of the telescopic mechanism 100 in a rectangular arrangement. A corresponding QR code containing the fixture's position information is affixed to each of the four corners of the fixture. When the picking / unloading component with positioning and correction functions approaches the fixture, the four barcode readers 300 simultaneously read the corresponding QR code on the fixture and transmit the position information to the controller. The controller analyzes and processes the information read by the four barcode readers 300 to more accurately determine the fixture's position, thereby achieving precise correction of the gripping mechanism 200. The rectangular arrangement of the four barcode readers 300 allows for the acquisition of fixture position information from multiple angles, improving the accuracy and reliability of position detection. Even if one barcode reader 300 malfunctions or has a reading error, the others can still provide accurate information, ensuring the stable operation of the correction system. Furthermore, QR code technology offers advantages such as large information storage capacity, fast reading speed, and high accuracy, meeting the needs of fixture position detection in complex production environments.

[0045] Reference Figure 1 The telescopic mechanism 100 includes a frame, a first telescopic section 110 connecting to the frame, and a second telescopic section 120. During operation, the first telescopic section 110 performs a large-range telescopic adjustment to bring the gripping mechanism 200 close to the target position. Then, the second telescopic section 120 performs a precise telescopic adjustment to accurately grip and place the goods. The two telescopic sections work together to meet both the need for a large range of telescopic movement and to achieve precise position adjustment, thus improving the overall performance of the equipment.

[0046] This utility model also proposes a transportation device, specifically an AGV (Automated Guided Vehicle) trolley, on which a picking and placing component with positioning and correction functions as described above is installed. The AGV trolley autonomously navigates within the production workshop using its own navigation system. Upon reaching a designated location, the picking and placing component with positioning and correction functions performs the picking and placing operations according to a preset program. For example, in a production workshop, the AGV trolley can pick up a fixture from one production process device according to a set route and then transport it to the next production process device for placement. Applying the picking and placing component with positioning and correction functions to the AGV trolley automates cargo transportation and picking / placing, improves the intelligence level of the production process, reduces manual operation, and lowers labor intensity and labor costs. Simultaneously, the precise picking and placing function of the picking and placing component with positioning and correction functions ensures the safety and accuracy of goods during transportation, improving the efficiency and quality of the entire production process.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
