After the locking is completed, the material is manually unloaded. There are a series of problems: product transfer cannot be achieved without human assistance, the space required is large, the structure is complex, it takes a long time, the degree of automation is relatively low, and there are safety hazards in manual operation. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a rotary large-stroke telescopic material picking and unloading device with a streamlined structure, reduced required space, greatly shortened time, no need for manual assistance, good matching of the assembly line, and fully meeting the automation standards. It solves the problems of the existing material picking mechanism having a short stroke that cannot meet the needs and the existence of safety hazards.

[0004] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a rotary large-stroke telescopic material loading and unloading device, comprising a rotatable workbench, a lower plate, an upper plate and a carrier, wherein a linear guide structure is provided between the workbench and the lower plate, between the lower plate and the upper plate, and between the upper plate and the carrier;

[0005] A first translation drive mechanism is also provided between the workbench and the lower plate, and a transmission structure is provided between the workbench and the upper plate, wherein the first translation drive mechanism comprises a first drive motor, a lead screw and a nut, wherein the power output end of the first drive motor is connected to the lead screw, the nut is sleeved on the lead screw, and the nut is fixed to the lower plate; the transmission structure comprises a lower rack fixed to the workbench, an upper rack fixed to the upper plate, and a gear rotatably connected to the lower plate, wherein the gear is meshed with the lower rack and the upper rack at the same time;

[0006] A second translation drive mechanism is also provided between the upper plate and the carrier, and the second translation drive mechanism includes a second drive motor, a driving wheel, a driven wheel, a synchronous belt and a connecting block, the synchronous belt is sleeved on the driving wheel and the driven wheel, and the output shaft of the second drive motor is connected to the driving wheel; the connecting block is fixed on the synchronous belt and the upper plate at the same time.

[0007] Furthermore, the carrier is in the shape of a flat plate, and a through hole is provided on the upper surface of the carrier.

[0008] Furthermore, the upper surface of the carrier is also provided with a plurality of limit blocks for limiting the position of the product.

[0009] Furthermore, a rotation driving mechanism is connected below the workbench, and the workbench is driven to rotate by the rotation driving mechanism.

[0010] Furthermore, the workbench is a platform that can rotate 360°.

[0011] Furthermore, both the lower plate and the upper plate are provided with through holes for reducing weight.

[0012] Furthermore, two sets of linear guide rail structures are provided between the workbench and the lower plate, between the lower plate and the upper plate, and between the upper plate and the carrier, and are symmetrically arranged with the center line of the workbench as the axis of symmetry.

[0026] The moving stroke of the carrier is doubled by the coordinated linkage of a gear and two racks. While ensuring sufficient stroke, the entire volume of the device is smaller and the structure is more compact.

[0027] A second translation drive mechanism 8 is also provided between the upper plate and the carrier, and the second translation drive mechanism 8 includes a second drive motor 81, a driving wheel 82, a driven wheel 83, a synchronous belt 84 and a connecting block 85. The synchronous belt is sleeved on the driving wheel and the driven wheel, and the output shaft of the second drive motor is connected to the driving wheel; the connecting block is fixed on the synchronous belt and the upper plate at the same time.

[0028] In this embodiment, the carrier is in the shape of a flat plate, and a through hole 41 is provided on the upper surface of the carrier. The first is to reduce weight and save materials, and the second is to avoid interference with the product placed on the carrier.

[0029] In this embodiment, a plurality of limiting blocks 42 for limiting the position of the product are further provided on the upper surface of the carrier.

[0030] In this embodiment, a rotation driving mechanism 9 is connected below the workbench, and the workbench is driven to rotate by the rotation driving mechanism.

[0031] In this embodiment, the workbench is a platform that can rotate 360 ​​degrees. The structure for driving the workbench to rotate is a prior art, such as through the cooperation of a motor and a cam divider, but it is not limited to this, so it is not repeated, and this part of the content does not belong to the content protected by the utility model.

[0032] In this embodiment, both the lower plate and the upper plate are provided with through holes 41 for reducing weight.

[0033] In this embodiment, two sets of linear guide rail structures are provided between the workbench and the lower plate, between the lower plate and the upper plate, and between the upper plate and the carrier, and are symmetrically arranged with the center line of the workbench as the symmetry axis, so that the translation process of the workbench is smoother and more stable.

[0034] Working principle or process:

[0035] The rotary drive mechanism 9 is used to rotate the workbench 360° to facilitate docking with the product transfer trolley and processing equipment; for example, when the workbench is at a certain angle, it is convenient for the workbench to dock with the product transfer trolley, and the product is transferred to the product transfer trolley through other mechanisms, and then the workbench is rotated at a certain angle to facilitate docking with the processing equipment of the assembly line to process the product;

[0036] A first translation driving mechanism 6, used for driving the vehicle to move in a first travel section;

[0037] The transfer structure 7 is used to drive the first section of the vehicle to increase the length of the travel;

[0038] A second translation driving mechanism 8, used for driving the vehicle to move to a second travel section;

[0039] Linear guide structure 5, used for guiding various motion mechanisms;

[0040] Carrier 4 is used for positioning the product.

[0041] Working process:

[0042] The workbench is driven by a rotary drive mechanism to adjust its posture to the required angle position, and the product is transferred to the product transfer cart through other mechanisms. The workbench is then rotated to a certain angle to facilitate docking with the processing equipment of the assembly line to process the product. During this process, the product only needs to be in the carrier and does not need to be moved to the processing equipment. Therefore, it has better compatibility with the assembly line, and the device can be used in various different workstations. At the same time, the carrier is driven to move to the required position through the first translation drive mechanism, the transmission structure and the second translation drive mechanism. Specifically, the first translation drive mechanism is precisely advanced by the motor lead screw, and 1 gear and 2 racks are synchronously linked to double the carrier's moving stroke. At the same time, the second translation drive structure uses a synchronous wheel and synchronous belt drive to transport the carrier to a farther distance, further increasing the moving stroke to meet more needs. After the product is processed, the carrier rotates in the opposite direction and can be unloaded in cooperation with other mechanisms.

[0043] The above description is only an embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present utility model.
