Description

Technical Field

[0001] This utility model relates to the technical field of feeding mechanisms, specifically to a rotary automatic loading and unloading device. Background Technology

[0002] Fiber laser engraving machines can be used to engrave positioning grooves, positioning holes, and fracture grooves in superhard materials such as PCD, PCBN, CVD, and ceramics. They can also be used for 3D engraving of metals such as cemented carbide, aluminum, and steel, and for precision cutting of thin sheet materials. In actual production, when using a laser engraving machine to process one end of a cylindrical superhard material rod, there is a high degree of reliance on manual loading and unloading. Laser engraving machines are generally designed with a single workpiece clamping structure, clamping one workpiece at a time. After processing, manual unloading and reloading of the next workpiece are required, thus consuming significant manual time and resulting in low efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a rotary automatic loading and unloading device to solve the problems of high dependence on manual labor and low efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rotary automatic loading and unloading device includes a linear module and a support plate mounted on and driven by the linear module. One end of the support plate is provided with a rotary mechanism, and the other end is provided with a workpiece clamping component. The rotary mechanism includes a rotary table and a drive mechanism for rotating the rotary table. The rotary table is provided with multiple material slots for placing workpieces.

[0006] The rotary automatic loading and unloading device also includes a lifting mechanism, which is equipped with a translation mechanism. The end of the translation mechanism is equipped with a gripping component, which is used to grip the workpiece to be processed from the material trough and transfer it to the workpiece clamping component and to place the processed workpiece into the material trough.

[0007] Furthermore, the linear module includes an X-axis linear module and a Y-axis linear module, with the Y-axis linear module connected to the X-axis sliding part of the X-axis linear module, and the support plate connected to the Y-axis sliding part of the Y-axis linear module.

[0008] Furthermore, the drive mechanism adopts a hollow rotating platform, and the turntable is connected to the upper side of the hollow rotating platform.

[0009] Furthermore, the turntable has a through hole at its center, and the support plate has a connecting column that passes through the through hole of the turntable and the hollow part of the hollow rotating platform. The lifting mechanism includes a lifting bracket, the lower part of which is fixed to the upper part of the connecting column.

[0010] Furthermore, the lifting mechanism includes a Z-axis slide cylinder, the cylinder body of which is fixed on the lifting bracket.

[0011] Furthermore, the translation mechanism includes an X-axis slide cylinder, the cylinder body of which is connected to the telescopic part of the Z-axis slide cylinder via a first connecting plate.

[0016] The beneficial effects of this utility model are:

[0017] This utility model of a rotary automatic loading and unloading device is used as an example in a fiber laser engraving machine. In operation, a worker first places multiple workpieces to be processed into the corresponding slots of the rotary table, allowing multiple workpieces to be placed at once. A linear module precisely positions the pneumatic chuck (workpiece clamping component) to the processing position corresponding to the laser processing head. During loading, the lifting and translation mechanisms work together, with the three-jaw pneumatic fingers (grippers) grabbing one workpiece at a time from the slot and transferring it to the pneumatic chuck for processing. The three-jaw pneumatic fingers also automatically place the processed workpiece into the material slot (raw material slot). The above steps are repeated until all workpieces on the rotary table have been processed. After the worker places multiple workpieces at once, the fiber laser engraving machine can automatically complete the sequential loading, processing, and unloading of multiple workpieces. For extended periods, no manual intervention is required, saving considerable worker time and significantly improving processing efficiency. This allows one worker to manage multiple machines, saving costs.

[0018] This utility model features a rotary automatic loading and unloading device that utilizes a combination of linear modules, three-jaw pneumatic fingers, a pneumatic chuck, and a sliding cylinder. It boasts a compact structure and high control precision. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0024] Embodiments of this utility model:

[0025] like Figures 1-3 As shown, the rotary automatic loading and unloading device is installed inside the fiber laser engraving machine. It includes a linear module and a support plate 3 mounted on and driven by the linear module. One end of the support plate 3 is equipped with a turntable mechanism that can hold multiple workpieces and rotate at a set time and angle according to a preset program. The other end of the support plate 3 is equipped with a workpiece clamping device for clamping the workpiece to be processed and sending it to the processing position for engraving by the fiber laser engraving machine.

[0026] In this embodiment, the workpiece is a cylindrical bar made of superhard material, with a diameter of less than 2 cm and a height of less than 5 cm. The machining required is to round the upper end of the workpiece.

[0027] The linear module includes an X-axis linear module 21 and a Y-axis linear module 22. The Y-axis linear module 22 is connected to the X-axis sliding part of the X-axis linear module 21, and the support plate 3 is connected to the Y-axis sliding part of the Y-axis linear module 22. The Y-axis linear module 22 can drive the support plate 3 to move in the Y-axis direction. The principle of the X-axis linear module 21 and the Y-axis linear module 22 is prior art, and their internal structure will not be described in detail. The bottom of the X-axis linear module 21 is fixed inside the fiber laser engraving machine by a fixing plate 1. The edge of the fixing plate 1 is provided with bolt holes for connection. In order to install the rotary automatic loading and unloading device of this utility model, it is necessary to make adaptive modifications (such as lengthening the size) to the corresponding parts of the existing fiber laser engraving machine to provide installation space.

[0028] When a fiber laser engraving machine is used for the initial processing of a workpiece, the X-axis linear module 21 and the Y-axis linear module 22 are used to send the workpiece to the processing position corresponding to the laser processing head.

[0029] The turntable mechanism includes a turntable 5 and a drive mechanism for rotating the turntable 5. The turntable 5 has multiple workpiece slots 51 for placing workpieces. The turntable 5 is a hollow disc, and the multiple workpiece slots 51 are evenly distributed along the circumference of the turntable 5. There are approximately 30 workpiece slots 51, and the number can be adjusted as needed. Each workpiece slot 51 is a circular slot, which can be understood as a blind hole, allowing cylindrical workpieces to be placed and supported. The diameter of the circular slot is larger than the diameter of the workpiece. The workpiece is placed vertically in the workpiece slot 51 for initial positioning. The operator places multiple workpieces one by one into the corresponding workpiece slots 51. The workpiece does not need to coincide with the center of the workpiece slot 51, reducing placement difficulty. The three-jaw pneumatic fingers 9 used subsequently grip the workpiece and provide centering, so it does not affect the final loading accuracy.

[0030] The drive mechanism employs a hollow rotary platform 4, with the turntable 5 bolted to the upper side of the hollow rotary platform 4. The hollow rotary platform 4 includes a side-mounted servo motor 41, located on one side of the Y-axis linear module 22. Driven by the servo motor 41, the hollow rotary platform 4 can drive the turntable 5 to rotate according to a set program. The hollow rotary platform 4 is existing technology, featuring a built-in reduction gear mechanism. Different output speeds can be obtained depending on the reduction ratio; it is a purchased component and therefore will not be described further. The use of the hollow rotary platform 4 results in a more compact overall structure, facilitates installation, provides high rotational positioning accuracy, and offers the advantages of low cost and high precision.

[0031] The turntable 5 has a through hole 52 at its center, which corresponds vertically to the hollow part of the hollow rotating platform 4. A connecting column is provided on the support plate 3, passing through the through hole 52 of the turntable 5 and the hollow part of the hollow rotating platform 4. The connecting column extends upward from the support plate 3 and protrudes from the upper side of the turntable 5.

[0032] A lifting mechanism 7 is provided on the support plate 3. The lifting mechanism 7 includes a lifting bracket 71, which is an L-shaped plate. The lower part of the lifting bracket 71 (the horizontal section of the L-shaped plate) is fixed to the upper part of the connecting column. When the turntable 5 rotates, the lifting bracket 71 remains stationary. In this embodiment, the lifting bracket 71 is directly connected to the connecting column, resulting in a compact structure. The turntable-type automatic loading and unloading device is installed as a whole in the fiber laser engraving machine, and it can move with the linear module, making it easy to control. In other embodiments, the bottom of the lifting bracket 71 can also be fixed to the Y-axis sliding part of the Y-axis linear module 22 via other connecting plates.

[0033] The lifting mechanism 7 is equipped with a translation mechanism. The lifting mechanism 7 includes a Z-axis slide cylinder 72. The cylinder body of the Z-axis slide cylinder 72 is fixed on the lifting bracket 71. The Z-axis slide cylinder 72 is used to drive the translation mechanism to lift.

[0034] The end of the translation mechanism is equipped with a gripper, which is a three-jaw pneumatic finger 9 used to grip the workpiece to be processed from the material trough 51 and transfer it to the workpiece clamping part and to place the processed workpiece into the material trough 51, thereby playing the role of transferring the workpiece.

[0035] The translation mechanism includes an X-axis slide cylinder 81, the cylinder body of which is connected to the telescopic part of a Z-axis slide cylinder 72 via a first connecting plate 73. A three-jaw pneumatic finger 9 is connected to the cylinder body of the X-axis slide cylinder 81 via a second connecting plate 82.

[0036] The second connecting plate 82 is connected to the upper side of the cylinder body of the X-axis slide cylinder 81 and the second connecting plate 82 is suspended. The three-jaw pneumatic fingers 9 are connected to the lower side of the suspended end of the second connecting plate 82. The three jaws are located at the bottom and clamp or release the workpiece through synchronous opening and closing actions.

[0037] The workpiece clamping device uses a pneumatic chuck 6. The main body of the pneumatic chuck 6 passes through and is fixed to the support plate 3, which can be connected by bolts. The clamping hole of the pneumatic chuck 6 is located at the top, and the workpiece is clamped from top to bottom. The pneumatic chuck 6 is a purchased part, and its principle is relatively mature, so it will not be described in detail.

[0038] The working principle of this rotary automatic loading and unloading device:

[0039] The operator places multiple workpieces to be processed into the corresponding material slots 51 one by one. When the fiber laser engraving machine is used for the first processing of a certain workpiece, it uses the cooperation of the X-axis linear module 21 and the Y-axis linear module 22 to precisely position the pneumatic chuck 6 to the processing position corresponding to the laser processing head. During loading, the Z-axis slide cylinder 72 rises first, and the X-axis slide drives the three-jaw pneumatic fingers 9 to move to a certain material slot 51. The Z-axis slide cylinder 72 then moves down to a set distance, and the three-jaw pneumatic fingers 9 clamp the upper part of the workpiece. The Z-axis slide cylinder 72 returns to its original position, and the X-axis slide drives the three-jaw pneumatic fingers 9 to move in the opposite direction to directly above the pneumatic chuck 6. Then, the Z-axis slide cylinder 72 moves down, and the three-jaw pneumatic fingers 9 release the workpiece, which falls into the clamping hole of the pneumatic chuck 6. The pneumatic chuck 6 clamps the workpiece and centers it. The Z-axis slide cylinder 72 returns to its original position, and the X-axis slide drives the three-jaw pneumatic fingers 9 to move in the opposite direction away from the processing position. Then, the laser processing head begins to process the upper part of the workpiece. After processing, the pneumatic chuck 6 is released, and the X-axis slide moves the three-jaw pneumatic fingers 9 towards the processed workpiece. Simultaneously, the Z-axis slide cylinder 72 moves downwards while the three-jaw pneumatic fingers 9 open, aligning with the workpiece downwards and clamping it. The Z-axis slide cylinder 72 moves upwards, and then the X-axis slide moves the three-jaw pneumatic fingers 9 towards the workpiece's material slot 51, placing the processed workpiece into the empty slot 51. The three-jaw pneumatic fingers 9 are then released, and the Z-axis slide cylinder 72 moves upwards, at which point the turntable 5 rotates a certain angle. The above steps are repeated to grab the next workpiece to be processed until all workpieces on the turntable 5 are processed. After the operator places multiple workpieces at once, the fiber laser engraving machine can automatically complete the sequential loading, processing, and unloading of multiple workpieces, meaning that manual operation is unnecessary for a considerable period. One machine saves a significant amount of worker time, allowing one worker to manage multiple machines, greatly improving processing efficiency and saving labor costs.
