The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Please refer to Figures 1 to 5 The CNC automatic loading and unloading device A of this embodiment includes a material-retrieving mechanism 1, a clamping mechanism 2 and a material storage mechanism 3;

[0038] The material storage mechanism 3 includes a material table 31 and a material tray 32 placed on the material table, and the material tray 32 is used to store the workpiece 4;

[0039] The material picking mechanism 1 includes a mechanical gripper 11, an X-axis driving member 12 and a Z-axis driving member 13. The mechanical gripper 11 is fixedly connected to one side of the X-axis driving member 12, and the other side of the X-axis driving member 12 is fixedly connected to the Z-axis driving member 13. The mechanical gripper 11 is used to grip the workpiece 4 on the material tray 32. The X-axis driving member 12 and the Z-axis driving member 13 drive the mechanical gripper 11 to place the workpiece 4 on the clamping mechanism 2.

[0040] The clamping mechanism 2 includes a double-layer workbench 21, a pressure plate 22 and a clamping assembly 23, the clamping assembly 23 includes an X-axis clamping piece 231 and a Z-axis clamping piece 232, the side of the pressure plate 22 is provided with an L-shaped fixed platform 221 adapted to the workpiece 4; the pressure plate 22 and the X-axis clamping piece 231 are horizontally installed on the upper layer of the double-layer workbench 21, and the clamping plane of the X-axis clamping piece 231 is opposite to the side of the L-shaped fixed platform 221; the Z-axis clamping piece 232 is vertically installed on the lower layer of the double-layer workbench 21, and the clamping plane of the Z-axis clamping piece 232 is opposite to the bottom surface of the L-shaped fixed platform 221, the workpiece 4 is clamped between the clamping plane of the X-axis clamping piece 231 and the side of the L-shaped fixed platform 221, and between the clamping plane of the Z-axis clamping piece 232 and the bottom surface of the L-shaped fixed platform 221.

[0041] In this embodiment, if Figure 3 As shown, the claws of the mechanical gripper 11 can move and are powered by a cylinder to loosen or clamp; the X-axis drive 12 is provided with a sliding component and a cylinder in the X-axis direction (horizontal direction) to drive the mechanical gripper 11 to move in the X-axis direction; the Z-axis drive 13 is provided with a sliding component and a cylinder in the Z-axis direction (vertical direction) to drive the mechanical gripper 11 to move in the Z-axis direction; through the cooperation of the X-axis drive 12 and the Z-axis drive, the mechanical gripper 11 is moved to the position of the material tray 32, and through the loosening and clamping operations of the mechanical gripper 11, the workpiece 4 on the material tray 32 is clamped.

[0042] like Figure 5 As shown, the pressure plate 22 is provided with an L-shaped fixing platform 221, and also has a groove adapted for the mechanical clamp 11 and a groove corresponding to the processing position of the workpiece 4, so that the mechanical clamp 11 can penetrate the L-shaped fixing platform 221 to place or clamp the workpiece 4. It is understood that the shape design of the pressure plate 22 can be adaptively adjusted according to the shape of the workpiece, and the working position of the pressure plate 22 can also be adaptively adjusted according to the number of clamping assemblies 23; the height of the L-shaped fixing platform 221 is less than the height of the workpiece 4.

[0043] like Figure 4As shown, the X-axis clamping member 231 clamps the workpiece 4 to the L-shaped fixed platform 221 from the side, and the Z-axis clamping member 232 presses the workpiece 4 downward to the L-shaped fixed platform 221 from above. Figure 6 The workpiece 4 (mobile phone frame) shown in the figure has its processing part on the side of the frame, so after the X-axis clamping member 231 and the Z-axis clamping member 232 have clamped the workpiece 4, the Z-axis clamping member 232 continues to clamp the workpiece 4, while the X-axis clamping member 231 is restored to its original position to leave processing space for the processing drill to process the workpiece 4. It should be noted that although Figure 4 There are two clamping mechanisms 2 shown, but in other embodiments there may be one or more clamping mechanisms 2 .

[0044] In this embodiment, the mechanical clamp 11, the X-axis drive 12 and the Z-axis drive 13 cooperate to realize automatic material removal of the workpiece 4, and the pressure plate 22 cooperates with the X-axis clamp 231 and the Z-axis clamp 232 to realize automatic locking of the workpiece 4, thereby eliminating the need for the operator to manually place the workpiece or use an air hammer to lock the workpiece, thereby freeing up manual operation and effectively improving production efficiency.

[0045] In some embodiments, as Figure 4 As shown, the clamping mechanism 2 includes two clamping assemblies 23 symmetrically positioned on either side of the pressure plate 22. The provision of two clamping assemblies 23 enables dual-station processing. Optionally, to improve the workpiece 4 retrieving process, two retrieving mechanisms 3 are also adaptively provided, with the spacing between the two retrieving mechanisms 3 being the same as the spacing between the two L-shaped fixed platforms.

[0046] In some embodiments, as Figure 7 and Figure 8 As shown, the X-axis clamping member 231 includes a first oil cylinder 2311, a first push block 2312, a second push block 2313, a first buffer block 2314 and a second buffer block 2315. The first oil cylinder 2311 is arranged on the upper layer of the double-layer workbench 21, one side of the first push block 2312 is fixedly connected to the piston rod of the first oil cylinder 2311, and the other side of the first push block 2312 is movably connected to the second push block 2313 through a spring 2316. The first buffer block 2314 and the second buffer block 2315 are movably connected to the two ends of the first push block 2312 facing the second push block 2313. The first buffer block 2314 and the second buffer block 2315 are both provided with a slide rail a, and the two ends of the first push block 2312 are provided with a slide groove b adapted to the slide rail.

[0047] In this embodiment, after the first cylinder 2311 is pushed out, the second push block 2312 contacts the workpiece 4. In order to protect the workpiece 4, the spring 2316 provides a buffering and rebound effect for the second push block 2312. The first buffer block 2314 and the second buffer block 2315 provide stability for the buffering and rebound process of the second push block 2312 to ensure that the second push block 2312 will not tilt and be misaligned with the contact surface of the workpiece 4, thereby ensuring the pressing effect of the second push block 2312 on the workpiece 4.

[0048] Optionally, a cover plate is provided above the X-axis clamp 231 to shield particles from falling during machining of the workpiece 4, thereby ensuring proper operation of the X-axis clamp 231 and increasing the service life of the X-axis clamp 231. It should be noted that the various components of the X-axis clamp 231 of this embodiment are replaceable to address potential malfunctions that may occur during long-term, large-scale production of the CNC automatic loading and unloading device.

[0049] In some embodiments, as Figure 8 As shown, the X-axis clamping member 231 further includes a pre-pressing block 2317 , and the pre-pressing block 2317 is fixedly connected to a side of the second pushing block 2313 facing the side of the L-shaped fixing platform 221 .

[0050] In this embodiment, the pre-pressing block 2317 can further provide a buffering effect for contacting the workpiece 4 to protect the workpiece 4. Optionally, a plurality of buffer blocks are provided on the side of the pre-pressing block 2317 facing the workpiece 4, and the buffer blocks are connected to the pre-pressing block by springs to further improve the buffering effect.

[0051] In some embodiments, as Figure 8 As shown, the X-axis clamping member 231 also includes a stabilizing plate 2318 and a slide rail assembly 2319. The slide rail assembly 2319 is arranged on the upper layer of the double-layer workbench 21. The bottom surface of the stabilizing plate 2318 is slidably connected to the slide rail assembly 2319, and the top surface of the stabilizing plate 2318 is fixedly connected to the second push block 2313.

[0052] In this embodiment, sufficient space is left for the workpiece 4, and the piston rod of the first oil cylinder 2311 can be set longer. As the piston rod is lengthened, the linear motion stability of the piston rod when it is pushed out will decrease. Therefore, this embodiment provides a stabilizing plate 2318 and a slide rail assembly 2319 to improve the linear motion stability of the second push block 2313 and ensure the clamping effect.

[0053] In some embodiments, as Figure 9 and Figure 10As shown, the Z-axis clamping member 232 includes a second oil cylinder 2321, a pull-down block 2322, a plurality of connecting rods 2323 and a plurality of pressure blocks 2324. The second oil cylinder 2321 is arranged on the lower layer of the double-layer workbench 21. The piston rod of the second oil cylinder 2321 is fixedly connected to one side of the pull-down block 2322. The connecting rod 2323 is fixedly connected to the other side of the pull-down block 2322. The connecting rod 2323 passes through the upper layer of the double-layer workbench 21 and is fixedly connected to the pressure block 2324. One end of the pressure block 2324 extends to the top of the L-shaped fixed platform 221, and there are gaps between the multiple pressure blocks 2324.

[0054] In this embodiment, the second oil cylinder 2321 is pushed out by default. When it is necessary to clamp the workpiece 4, the second oil cylinder 2321 retracts the piston rod, causing the pull-down block 2322 to move downward, thereby driving the pressure block 2324 to move downward, thereby pressing the workpiece 4 against the L-shaped fixed table 221. Optionally, the spacing between the multiple pressure blocks 2324 can be adaptively adjusted according to the processing position of the workpiece 4; the upper side of the end of the pressure block 2324 closest to the L-shaped fixed table is inclined, so that when the workpiece 4 contacts the pressure block 2324 during the process of placing the workpiece 4 on the L-shaped fixed table 221 by the material removal mechanism 2, it can move downward along the inclined surface to the L-shaped fixed table.

[0055] In some embodiments, as Figure 11 As shown, the device further includes a dual-axis driving base 5 , and the double-layer workbench 21 is arranged above the dual-axis driving base 5 and is fixedly connected to the dual-axis driving base 5 .

[0056] In this embodiment, the dual-axis drive base 5 is a dual-axis drive base based on X-axis drive and Y-axis drive, so as to facilitate adjustment of the positions of the clamping mechanism 2 and the material storage mechanism 3 relative to the material picking mechanism 1, thereby facilitating the loading and unloading of materials by the material picking mechanism 1.

[0057] In some embodiments, as Figure 12 As shown, the material tray 32 is provided with a plurality of workpiece slots 321 adapted to the workpiece 4 , and the workpiece slots 321 are provided with a plurality of hollow openings 322 adapted to the mechanical grippers 11 .

[0058] In this embodiment, the workpiece slot 321 can ensure that the mechanical gripper 11 can stably grip the workpiece 4 in the target posture, and the hollow opening 322 can facilitate the mechanical gripper 11 to extend into the material tray to grip the workpiece 4. Optionally, the table top of the material table is a hollow structure to further facilitate the operation of the mechanical gripper 11.

[0059] See Figure 13The present invention shows a schematic diagram of the structure of a CNC machining device according to an embodiment of the present invention. The CNC machining device includes a machining drill assembly B and the aforementioned CNC automatic loading and unloading device A. The machining drill assembly B of this embodiment is used to machine a workpiece after the CNC automatic loading and unloading device A clamps the workpiece.

[0060] The working method of the CNC processing equipment includes:

[0061] Step 101: Control the X-axis drive and the Z-axis drive of the material picking mechanism to drive the mechanical gripper of the material picking mechanism to place the workpiece on the material tray on the L-shaped fixed platform of the clamping mechanism;

[0062] Step 102: Control the clamping plane of the X-axis clamping member and the clamping plane of the Z-axis clamping member of the clamping mechanism to move toward the L-shaped fixed table to clamp the workpiece on the L-shaped fixed table;

[0063] Step 103, controlling the machining drill to machine the workpiece;

[0064] Step 104: After the workpiece processing is completed, the X-axis clamping member and the Z-axis clamping member are controlled to release the workpiece, and the mechanical clamp is controlled to place the workpiece on the tray to complete the workpiece processing.

[0065] This embodiment realizes automatic material removal of the workpiece through the cooperation of the mechanical clamp, X-axis drive and Z-axis drive, and realizes automatic locking of the workpiece through the cooperation of the pressure plate with the X-axis clamp and Z-axis clamp, thereby eliminating the need for the operator to manually place the workpiece or use an air batch to lock the workpiece. The entire process is fully automatically controlled, freeing up manual operation and effectively improving production efficiency.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
