[0061] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0062] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0064] like Figure 1-Figure 5 As shown, the embodiment of the present application provides a transfer device, which includes a base 1, a workbench 2 and a conveyor 3. The base 1 forms the main body and supporting foundation of the transfer device to ensure the overall stability of the transfer device; the workbench 2 is connected to the base 1, and the workbench 2 is used to carry the material to be processed and slide relative to the base 1 along the first direction, that is, the material to be processed moves with the workbench 2 to the target position for subsequent processing such as punching; the conveyor 3 is connected to the base 1 in a liftable manner, and the conveyor 3 is used to dock with the workbench 2 along the height direction to supply the material to be processed to the workbench 2 in the first direction or receive the material to be processed conveyed by the workbench 2, and the material is automatically taken and placed through the conveyor 3, which saves labor costs and transfer time, and improves the processing efficiency of the material. In addition, since the workbench 2 and the conveyor 3 are both connected to the same base 1, the integration of the transfer device is improved, the cost is reduced, and the space occupied by the transfer device is reduced, and the space utilization rate is improved.

[0065] Specifically, the workbench 2 can be positioned and coordinated with processing components such as punching components to achieve subsequent processing such as punching of materials. The conveyor table 3 can load the materials to be processed manually or by a panel robot. The conveyor table 3 can convey the materials to be processed to the workbench 2 for subsequent processing, thereby realizing automatic loading; the conveyor table 3 can remove the materials to be processed from the workbench 2, thereby realizing automatic unloading.

[0066] The first direction and the height direction intersect each other. For example, the first direction can be a horizontal direction or an inclined direction, so as to form a three-dimensional utilization of the space of the base 1, so as to reasonably arrange it in the limited plane area of ​​the base 1, make the overall structure more compact, and improve the space utilization rate. In each embodiment of the present application, only the first direction is a horizontal direction as an example for detailed description.

[0067] Furthermore, in the horizontal plane, at least a portion of the conveyor platform 3 is located within the movement area of ​​the workbench 2. That is to say, when the workbench 2 moves toward the conveyor platform 3 to the end of the stroke, the conveyor platform 3 and the workbench 2 have a certain overlapping area in the horizontal plane, which reduces the plane area occupied by the conveyor platform 3 and the workbench 2, thereby reducing the footprint of the transfer device and further improving space utilization.

[0068] Furthermore, in the horizontal plane, the workbench 2 can move beyond the outline of the conveyor platform 3. That is, when the workbench 2 moves to the end of the stroke in the direction away from the conveyor platform 3, there is no overlapping area between the conveyor platform 3 and the workbench 2 in the horizontal plane. For example, the conveyor platform 3 and the workbench 2 are arranged adjacent to each other or spaced apart from each other in the horizontal direction to avoid interference of the workbench 2 with the movement of the conveyor platform 3, thereby ensuring that the conveyor platform 3 can move to the target position.

[0069] Furthermore, in the vertical plane, the conveyor table 3 can move beyond the height range of the workbench 2. At this time, the conveyor table 3 and the workbench 2 have no overlapping height in the vertical plane. For example, the conveyor table 3 and the workbench 2 can be arranged adjacent to or spaced apart in the vertical direction to avoid the conveyor table 3 interfering with the movement of the workbench 2, thereby ensuring that the workbench 2 can move to the target position.

[0070] Furthermore, in the vertical plane, the conveyor platform 3 can move to within the height range of the workbench 2. At this time, the conveyor platform 3 and the workbench 2 have a certain overlapping height in the vertical plane to ensure that the conveyor platform 3 and the workbench 2 can be docked along the height direction, so that materials can be transferred between the conveyor platform 3 and the workbench 2.

[0071] Furthermore, the conveying platform 3 includes a lifting mechanism 31 and a conveying mechanism 32. The lifting mechanism 31 is installed on one side of the base 1. The lifting mechanism 31 is connected to the conveying mechanism 32 and is used to drive the conveying mechanism 32 to move in the vertical direction. The lifting mechanism 31 can be any mechanism that can output linear motion, such as a cylinder, a screw nut mechanism, or a gear rack mechanism.

[0072] Furthermore, the workbench 2 further includes a first conveying assembly 21, which is used to drive the material to be processed on the workbench 2 to be conveyed to the conveying platform 3 along the first direction, or to convey the material to be processed to the workbench 2 through the conveying mechanism 32 on the conveying platform 3. In other words, the first conveying assembly 21 of the workbench 2 and the conveying mechanism 32 of the conveying platform 3 are connected to each other, so that the material can be smoothly transferred between the conveying platform 3 and the workbench 2.

[0073] Furthermore, the first conveying assembly 21 can be installed on the workbench 2 in a movably movable manner. The first conveying assembly 21 of the workbench 2 can be moved up and down, thereby changing the height of the first conveying assembly 21, which can both reduce the conveying resistance of the material and provide reliable support for the material. Specifically, when the first conveying assembly 21 is raised, the first conveying assembly 21 is higher than the bearing surface of the workbench 2, thereby forming a suspended area between the material to be processed and the bearing surface of the workbench 2, thereby avoiding friction between the material and the bearing surface of the workbench 2 during the conveying process; when the first conveying assembly 21 is lowered, the first conveying assembly 21 and the bearing surface of the workbench 2 are aligned with each other, thereby forming a reliable contact between the material and the bearing surface of the workbench 2, thereby ensuring that the workbench 2 can provide reliable support for the material.

[0074] Further, the docking between the first conveying assembly 21 of the workbench 2 and the conveying mechanism 32 of the conveying platform 3 may include position docking, for example, the first conveying assembly 21 and the conveying mechanism 32 are aligned with each other in the height direction, so as to avoid vibration during the material transfer process, which affects the stability of the material transfer. The docking between the first conveying assembly 21 of the workbench 2 and the conveying mechanism 32 of the conveying platform 3 may include transmission docking, for example, the first conveying assembly 21 and the conveying mechanism 32 may be meshed with each other through a gear set, so that the first conveying assembly 21 and the conveying mechanism 32 can act synchronously, prevent the material from slipping during the conveying process (i.e., the material and the first conveying assembly 21 slide relative to each other), improve the conveying efficiency, and ensure the conveying quality.

[0075] Furthermore, the first conveying assembly 21 includes a first mounting frame 211, a lifting belt assembly 212 and a gear driving assembly 213. The first mounting frame 211 is connected to the workbench 2, and is used to realize the installation and fixation of the first conveying assembly 21; the lifting belt assembly 212 is connected to the first mounting frame 211 in a liftable manner, and is used to change the relative height between the first conveying assembly 21 and the workbench 2; the gear driving assembly 213 is used to drive the lifting belt assembly 212 to move along the first direction, thereby realizing material transportation.

[0076] Furthermore, the conveying mechanism 32 includes two second conveying components 321 arranged in sequence along the height direction, wherein one second conveying component 321 is used to convey the material to be processed to the workbench 2, and the other second conveying component 321 is used to receive the material to be processed supplied by the workbench 2. In other words, the two second conveying components 321 are stacked, and the conveying directions of the two second conveying components 321 are opposite, so that the conveying platform 3 can simultaneously realize the taking and placing of the material to be processed, further improving the processing efficiency of the material.

[0077] Specifically, a detailed description is given by taking the conveying direction of the upper second conveying assembly as the conveying direction of the conveying platform 3 pointing to the workbench 2 and the conveying direction of the lower second conveying layer assembly 321 as the workbench 2 pointing to the conveying platform 3. When the conveying platform 3 moves to the upper second conveying assembly 321 and docks with the workbench 2, the conveying platform 3 conveys the material to be processed to the workbench 2 to realize automatic loading; when the conveying platform 3 moves to the lower second conveying assembly 321 and docks with the workbench 2, the conveying platform 3 receives the material to be processed supplied by the workbench 2, thereby removing the material from the workbench 2 to realize automatic unloading.

[0078] Furthermore, the second conveying component 321 includes a motor 3211, a transmission shaft 3212, and a plurality of synchronous belt components 3213; the transmission shaft 3212 is connected to the motor 3211, and the plurality of synchronous belt components 3213 are respectively connected to the transmission shaft 3212 and are arranged at intervals along the direction of the transmission shaft 3212. The motor 3211 is used to drive the transmission shaft 3212 to drive the plurality of synchronous belt components 3213 to move synchronously, so that a flexible contact is formed between the material to be processed and the second conveying component 321, thereby reducing bumps or wear generated during the material conveying process.

[0079] Furthermore, the synchronous belt assembly 3213 includes a second mounting frame 3213a, two pulleys 3213b and a synchronous belt 3213c. The second mounting frame 3213a is connected to the transmission shaft 3212, and is used to realize the installation and fixation of the synchronous belt assembly 3213; the two pulleys 3213b are arranged at intervals along the length direction of the second mounting frame 3213a, and one of the pulleys 3213b is connected to the transmission shaft 3212, so that the pulley rotates with the transmission shaft 3212; the synchronous belt 3213c is supported on the outer surfaces of the two pulleys 3213b, and meshes with the pulleys 3213b, so that the synchronous belt 3213c rotates synchronously with the pulleys 3212b.

[0080] Furthermore, two adjacent synchronous belt assemblies 3213 among the plurality of synchronous belt assemblies 3213 form a first workstation 322, and a plurality of materials to be processed are respectively located on each first workstation 322. The motor 3211 drives the plurality of synchronous belt assemblies 3213 to move in parallel, so that the materials to be processed located at each first workstation 322 move along the first direction at the same time, thereby being able to simultaneously transport a plurality of materials to be processed, thereby further improving the processing efficiency.

[0081] Furthermore, each first station 322 is provided with a guide structure such as a pin guide 3221, and the pin guide 3221 is formed with a pin guide slot 3221a for guiding the material to be processed, that is, the pin on the surface of the material to be processed can slide along the pin guide slot 3221a, thereby guiding the material to be processed and ensuring that the material to be processed moves in a straight line at each first station 322. Each first station 322 can be provided with position sensors such as edge finding sensors, material detection sensors, and in-place sensors to accurately locate and pick up the material to be processed.

[0082] Furthermore, the pin guide 3221 is also formed with a guide opening 3221b, which is located at the entrance of the guide slot 3221a, and the guide opening 3221b is trumpet-shaped, that is, along the direction approaching the guide slot 3221a, the width of the guide opening 3221b gradually decreases to adjust the position of the pin so that the pin can be more easily aligned and slide into the pin guide slot 3221a.

[0083] Specifically, the pin guide 3221 may include two guide rods 3221c arranged in parallel, and the gap between the two guide rods 3221c forms a pin guide slot 3221a and a guide opening 3221b. In other words, the two guide rods 3221c are parallel to each other, thereby forming the pin guide slot 3221a; the two guide rods 3221c are separated from each other at a section near the entrance, thereby forming a trumpet-shaped guide opening 3221b.

[0084] Furthermore, the lifting mechanism 31 includes a gear drive mechanism 311 and a rack support member 312. The gear drive mechanism 311 is connected to the base 1, and the gear drive mechanism 311 can output rotational power; one end of the rack support member 312 is movably connected to the base 1, and the other end is fixedly connected to the conveying platform 3. The rack support member 312 is meshed with the gear drive mechanism 311 to form a gear rack mechanism, so that the rack support member 312 and the conveying platform 3 are driven to move in the vertical direction through the rotational power of the gear drive mechanism 311, with high transmission efficiency and stable and reliable movement.

[0085] Furthermore, two rack support members 312 are provided and spaced apart along the base, and the gear drive mechanism is used to drive the two rack support members 312 to move synchronously in the vertical direction, thereby forming multiple force application points on the conveyor platform 3, increasing the force span of the conveyor platform 3, and further improving the support stability and movement stability of the conveyor platform 3.

[0086] Further, the gear drive mechanism 311 includes a driving member 3111 and a driving gear 3113. The driving member 3111 can be a device such as a motor that can output rotational power. The driving gear 3113 is directly connected to the output shaft of the driving member 3111, or the driving gear 3113 is indirectly connected to the output shaft of the driving member 3111 through a transmission mechanism such as a gearbox, so that the driving member 3111 drives the driving gear 3113 to rotate.

[0087] In one embodiment, the gear drive mechanism 311 further includes a drive shaft 3112, and the drive member 3111 is indirectly connected to the drive gear 3113 through the drive shaft 3112. Two drive gears 3113 are provided and are respectively provided at both ends of the drive shaft 3112. The two drive gears 3113 are respectively engaged with the two rack support members 312. The drive member 3111 is used to drive the drive shaft 3112 to drive the drive gears 3113 at both ends to rotate, so that the two rack support members 312 can be raised and lowered synchronously, thereby improving the stability of the conveyor platform movement.

[0088] In another embodiment, the gear drive mechanism 311 includes two driving members 3111 and two driving gears 3113. Each driving member 3111 drives a corresponding driving gear 3113 to rotate. The two driving gears 3113 are respectively engaged with two rack support members 312. The output shaft of the driving member 3111 is used to drive the driving gear 3113 to rotate, so that the two rack support members 312 can be raised and lowered synchronously, thereby improving the stability of the conveyor platform movement.
