Description

TECHNICAL FIELD

[0001] The present application relates to the field of stamping processing, in particular to a workpiece transfer device. BACKGROUND

[0002] In the prior art, flow line production has become an important way of industrial manufacturing, and its core lies in realizing efficient connection and material flow between processes. However, due to the differences in production environment and location, part of the continuous production line is difficult to be completely connected in actual application, and there is often an intermediate break between different processes. In this case, workpiece transfer devices must be used to connect the disconnected processes to realize efficient transfer of materials. The widely used transfer devices at present mainly include fixed conveyors or other conveying mechanisms. These devices have become a common choice in many industrial production lines because of their simple structure, low cost and high running efficiency.

[0003] However, although the fixed transfer device has certain advantages, it also has great limitations in actual use. Due to the fixed design, such devices cannot be flexibly adjusted in position, which limits the efficient use of production space, especially in the case of frequent adjustment or limited space in the production scene, which is not flexible enough. Therefore, in order to solve this problem, mobile handling devices based on automatic guided vehicles (AGV) have been gradually introduced in recent years. Such devices can flexibly respond to changing production needs and realize flexible connection between processes. However, most of the AGV handling devices on the market currently use complex multi-axis mechanical arms or highly automated intelligent designs, which have complex structures, high manufacturing and maintenance costs, and often exceed the affordability of small and medium-sized enterprises. In addition, the complex mechanical structure increases the difficulty of device operation, which requires higher skills of operators, and is not conducive to large-scale promotion.

[0004] In addition to the above problems, the existing AGV handling device usually adopts a multi-layered design to provide more storage capacity in a limited space. Although this design can temporarily improve the material storage capacity, the stacked structure requires layer-by-layer operation to take and place workpieces. Whether it is completed by a mechanical arm or manually, it requires additional time and effort, resulting in a decrease in production efficiency.

[0005] Based on the above problems, it is of great significance to develop a new type of workpiece transfer device. CONTENT OF THE INVENTION

[0006] The purpose of the present application is to at least overcome one of the deficiencies of the prior art, and to provide a workpiece transfer device that combines an AGV chassis and an inclined shelf design to realize efficient transfer and automated access of workpieces, and to solve the problems of complex access and low efficiency of existing AGV handling devices.

[0007] To achieve the above objectives, this application discloses a workpiece transfer device, which includes a traveling chassis, a storage rack fixed to the chassis, and a receiving and transferring component mounted on the chassis via vertical guide rails and capable of moving along the height direction. The receiving and transferring component is arranged opposite to the storage rack, and the two cooperate to achieve automated loading and unloading of workpieces. The storage rack consists of a structural frame and working partitions arranged along the height direction within the structural frame. Storage positions for accommodating materials are formed between adjacent working partitions. One end of the storage rack is a feeding port, and the end opposite to the feeding port is a discharging port.

[0008] To further optimize the functional design of the device, the working partition is arranged at an angle, with its inlet position higher than its outlet position. The preferred angle range is 3 to 8 degrees. This angled design allows the material to slide smoothly and be stored stably without external force by utilizing gravity, thereby reducing additional energy consumption and simplifying the complexity of the mechanical drive device.

[0009] An electromagnetic component is embedded near the feed inlet of the working partition. This component is electrically connected to an external control system via a guide rail structure and is used to precisely position and fix the material during the feeding process. The on / off state of the electromagnetic component is controlled by the control system, and rapid start and stop enable magnetic attraction and fixation of the material, ensuring the stability of the material within the storage position and providing reliable support for the loading process.

[0010] Furthermore, to optimize the material handling operation, a pneumatically driven telescopic stop pin is installed near the discharge port of the working partition. The extension and retraction of the stop pin is controlled by an external control system. Under normal conditions, the stop pin is extended to prevent material from sliding out of the storage position; when material needs to be removed, the stop pin retracts under the drive of the pneumatic device, allowing the material to slide smoothly out of the storage position. This design significantly simplifies the traditional layer-by-layer material handling process and effectively improves operational efficiency.

[0011] As an optional technical solution, guide wheels are provided at the discharge port and / or inlet to further improve the stability and guidance of the material. The arrangement of the guide wheels reduces the frictional resistance during the material sliding process, ensuring that the material maintains an accurate position during loading and unloading, thereby further improving the operational reliability and smoothness of the device.

[0012] Compared with the prior art, this application has at least one of the following beneficial effects:

[0013] 1. Increased flexibility

[0014] By adopting the AGV chassis and the combination of the storage shelf, the device can move flexibly in the production space, overcoming the limitations of traditional fixed transfer devices that cannot adjust positions, effectively improving the utilization rate of the production space, and meeting the needs of dynamically adjusting the production process.

[0015] 2. Simplified operation and improved efficiency

[0016] The inclined work partition realizes automatic sliding storage of materials through gravity, reducing the dependence on additional driving force, optimizing the material storage and retrieval operation process, avoiding the complex steps of traditional layer-by-layer material retrieval, and significantly reducing the time cost of manual and mechanical arm operation.

[0017] 3. Enhanced stability and precision

[0018] The electromagnetic components provided at the inlet provide precise material positioning and fixing functions, ensuring stable storage of materials at the storage site; the pneumatic telescopic blocking pin configured at the outlet further improves the safety and smoothness of the material retrieval process, thereby ensuring the stability of the device operation.

[0019] 4. Structure optimization and energy consumption reduction

[0020] The design of the inclined partition and the auxiliary guidance of the guide wheel reduce the resistance in the material sliding process, simplify the mechanical driving structure, reduce the energy consumption during equipment operation, and reduce the maintenance complexity and cost, providing reliable protection for long-term stable operation.

[0021] The above listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the embodiments or other description parts of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0029] Referring to the accompanying drawings Figure 1 and 2 The present embodiment provides an exemplary structure of a workpiece transfer device, which is mainly used for material transfer between processes in the production line process of stamping parts production, to solve the problems of insufficient flexibility, complex operation and low running efficiency of existing transfer devices. The device comprises a walking chassis 1, a storage shelf 2 fixed on the chassis, and a receiving and delivering assembly 3 installed on the chassis through vertical guide rails and capable of moving in the height direction. The structure, function, working principle and mutual cooperation of each component are described in detail below.

[0030] Although the above components and methods are described in detail in the present embodiment, those skilled in the art should understand that these descriptions are for better illustration of the present application and do not constitute a limitation on the scope of protection of the present application.

[0031] One of the core components of the device is the walking chassis 1, which is an automatic guided vehicle (AGV) responsible for the movement and power support of the entire device. The walking chassis is made of high-strength steel and coated with an anti-oxidation coating to improve corrosion resistance. Inside the chassis are integrated drive modules, navigation modules, power modules, and communication modules. The drive module is composed of high-performance brushless DC motors, reducers, and differential control systems, which, in combination with four sets of high-load polyurethane universal wheels, support straight-line movement, in-place steering, and multi-directional sliding functions. The navigation module combines laser navigation and inertial navigation technology. The laser navigation sensor at the front of the chassis scans environmental information in real time and provides accurate positioning, while the inertial navigation module ensures continuous travel and adapts to the path planning requirements in complex workshop environments. The chassis is equipped with a high-capacity lithium battery pack, which supports long-term operation of the device and shortens the charging time through a fast charging interface. The communication module supports dual-mode communication of wireless local area network (Wi-Fi) and industrial Ethernet, enabling data interaction with external control systems and ensuring that the device is always in optimal working condition.

[0032] The control logic and operation steps to achieve the above functions are obvious to those skilled in the art, and therefore the present application does not disclose them in detail.

[0033] The storage rack 2 is an important component of the workpiece transfer device for material storage and guidance, designed to combine storage function and dynamic transfer requirements to ensure stable operation, smooth sliding and easy maintenance of workpieces during loading and unloading.

[0034] The storage rack 2 is fixedly installed above the walking chassis 1 and consists of a structural frame 4 and several working partitions 5. The structural frame 4 is composed of four main support columns and multiple transverse support beams. The main support columns are made of high-strength aluminum alloy profiles, which are anodized on the surface to have excellent corrosion resistance and light weight, while ensuring the overall stability of the structure. The support columns are connected by transverse support beams made of wear-resistant alloy steel, which are fixed to the main support columns by multi-point welding to ensure that the rack does not deform or loosen during high-speed movement and loading and unloading operations.

[0035] The working partitions 5 are made of wear-resistant steel plates with a thickness of 3 mm and are hardened on the surface for high strength and impact resistance. Each partition is fixed to the structural frame 4 by removable bolts for easy maintenance, adjustment or replacement later. The inclined design of the working partitions 5 is a key feature of the rack, with the inlet 6 positioned higher than the outlet 7. The inclination angle is preferably 5°, which allows the material to naturally slide to the designated storage position using gravity, eliminating the need for additional driving devices. This design not only reduces energy consumption, but also significantly simplifies the device structure.

[0036] The innovation of the present application lies in the design of the inclined work partition 5, while other structural components can be easily implemented by those skilled in the art based on existing technology.

[0037] In order to improve the versatility and adaptability of the storage position, the spacing of the work partition 5 can be adjusted according to the size and requirements of different workpieces. A plurality of vertically distributed bolt mounting holes are provided on the support column, and the user can change the height spacing of the partition by adjusting the installation position of the bolt, thereby flexibly adapting to different production scenes. The two ends of the storage position are open feeding port 6 and discharging port 7, respectively, so as to realize barrier-free cooperation with the pickup assembly 3.

[0038] Near the feeding port 6, the bottom of the work partition 5 is configured with an electromagnetic assembly for precise positioning and fixing of the workpiece during loading. The electromagnetic assembly is composed of high magnetic flux silicon steel sheet and coil winding, and can realize precise on-off operation through the control system. When the material is loaded into the storage position, the electromagnetic assembly will be powered to generate magnetic attraction force, adsorb the sliding workpiece and prevent it from causing a larger impact due to inertia, so that it is stably dropped into the storage position. After positioning is completed, the electromagnetic assembly continues to fix the workpiece. This design further improves the accuracy of loading and the stability of storage.

[0039] A pneumatic driven telescopic blocking pin is provided near the discharging port 7 of the storage shelf 2 for controlling the sliding of the material. The blocking pin is made of wear-resistant alloy steel, and the pneumatic device drives its telescopic action through the electromagnetic valve. In normal state, the blocking pin is in the extended position, forming a mechanical barrier to prevent the material from accidentally sliding out; when the pickup assembly 3 is ready to take the material, the control system instructs the pneumatic device to retract the blocking pin, releasing the material, to ensure that the workpiece smoothly slides into the hopper of the pickup assembly 3.

[0040] In addition, in order to reduce the frictional resistance of the material during sliding and improve the stability of sliding, a rolling guide wheel is installed at the feeding port 6 and the discharging port 7, respectively. The guide wheel is made of polyurethane coated stainless steel, and the bearing adopts a double sealing structure to improve the durability. The rolling guide wheel can reduce the friction coefficient between the material and the partition, while ensuring that the material maintains a stable guide track during sliding.

[0041] The pickup assembly 3 is installed on the walking chassis 1 through vertical guide rails and can be freely adjusted in the height direction. The vertical guide rail is made of high-precision stainless steel material, and the guide rail system cooperates with high-load sliding blocks and synchronous belt transmission mechanism to ensure the stability and positioning accuracy of the pickup assembly during upward and downward movement. The core part of the pickup assembly is a rotatable hopper made of high-strength aluminum alloy, which has an arc structure inside for accommodating and transferring materials. The rotation function of the hopper is driven by a servo motor through a gear reduction mechanism to realize 360° rotation, which can be flexibly adjusted to the feeding port 6 or discharging port 7 position of the storage shelf 2.

[0042] Those skilled in the art will understand that the servo motor control and gear reduction mechanism described above are for the purpose of illustrating embodiments of the present application and not for limiting the scope of the present application.

[0043] While exemplary embodiments of the present disclosure have been described, it is to be understood that the exemplary embodiments of the present disclosure are provided by way of illustration only, and nothing in the present disclosure is intended to be limiting. Rather, the present disclosure is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure. The present disclosure is limited only by the following claims and their equivalents.
