[0033] The blades are placed on the feeding mechanism 2, the appearance and quality of the blades are checked by the detection mechanism 3, the size precision is verified, the blades are clamped by the mechanical hand 4 to the rotating disc 5, then the blades are placed on the placing rods 7, the placing rods 7 and the blades are limited by the limiting mechanism, the movement of the placing rods 7 and the mounting seats 6 is prevented, and the blades can be stably placed on the placing rods 7, when the blades on the placing rods 7 of the mounting seats 6 close to the mechanical hand 4 are placed, the rotating disc 5 is driven to rotate by the driving assembly, the mounting seats 6 and the placing rods 7 without blades are rotated to the mechanical hand 4, and the above operation is repeated to place the blades on the placing rods 7, when the placing rods 7 on the four mounting seats 6 are filled with blades, the blades can be taken off from the placing rods 7 by moving the limiting mechanism for subsequent operation, so that the operation rhythm when taking the blades is prevented from being too fast, the blades are prevented from being taken off in disorder and falling off, and the work efficiency is improved.

[0036] like Figures 1 to 3 As shown, the drive assembly includes a cam divider 8, a rotating shaft 9, and a first motor 10. The rotating shaft 9 is fixedly connected to the bottom of the turntable 5. One end of the rotating shaft 9 passes through the top of the assembly base 1 and is fixedly connected to the output shaft of the cam divider 8. Baffles are fixedly connected around the top of the assembly base 1. The feeding mechanism 2, the detection mechanism 3, the robot arm 4, the turntable 5, the drive assembly, the mounting base 6, the placement rod 7, and the limiting mechanism are all located inside the baffles.

[0037] The first motor 10 drives the rotating shaft 9 to rotate, which in turn drives the cam divider 8 to rotate. After the blade on one of the mounting seats 6 on the turntable 5 is placed, the other unplaced mounting rods 7 can be rotated to the robot arm 4, which facilitates the placement of new blades and improves the continuity of blade placement. The baffle can protect against blades popping out and accidentally injuring the operator.

The bottom of the moving block 12 is slidably connected to the top of the mounting base 6. The middle part of the fixed block 11 is movably connected to the placement rod 7.

The moving block 12, the fixed block 11, the connecting rod 13, and the limiting block 14 are symmetrically arranged with respect to the center of the placement rod 7.

[0039] When the blades on the placing rod 7 are full, first, the first electric push rod 15 is started to drive the moving block 12 to move along the top of the mounting seat 6, so that the moving block 12 drives the two connecting rods 13 on the top to move close to each other, and when the connecting rod 13 drives the limiting block 14 to move to the two sides of the blade, the second electric push rod 16 is started to extend, so that the second electric push rod 16 is inserted with the limiting groove, thereby limiting the position of the two limiting blocks 14, so that the limiting block 14 is fixed on the top of the blade. The symmetrical arrangement of the moving block 12, the fixed block 11, the connecting rod 13 and the limiting block 14 can improve the stability of the blade limiting, prevent the unstable connection of the placing rod 7, and prevent the blade from shaking during the rotation of the rotating disc 5, thereby affecting the assembly effect.

[0041] When the first electric push rod 15 drives the moving block 12 to move along the top of the mounting seat 6, so that the moving block 12 drives the first magnetic block 17 to move away from the second magnetic block 18, when the moving block 12 drives the connecting rod 13 and the limiting block 14 to move to the top of the blade, the first magnetic block 17 at the bottom of the moving block 12 is magnetically connected with the third magnetic block 19, thereby fixing the position of the moving block 12, and facilitating to improve the stability of the limiting block 14 and the moving block 12.

[0042] As shown in Figures 5 to 7 The two sides of the first electric push rod 15 are provided with the moving rod 20, and the moving rod 20 is fixedly connected with the moving block 12. The side of the moving rod 20 away from the moving block 12 is provided with the moving plate 21, and the moving plate 21 is fixedly connected with the inserting rod 22. The two sides of the fixed block 11 and the bottom outside of the placing rod 7 are provided with the inserting groove, and the inserting rod 22 is located in the inserting groove of the fixed block 11. The side of the moving plate 21 close to the fixed block 11 is fixedly connected with the two compression springs 23, and one end of the compression spring 23 is fixedly connected with the fixed block 11.

[0043] When the first electric push rod 15 drives the moving block 12 to move along the top of the mounting seat 6, the moving block 12 drives the moving rod 20 to move towards the fixed block 11, so that the moving rod 20 pushes the moving plate 21 to move and compresses the compression spring 23, so that the moving plate 21 drives the inserting rod 22 to move towards the inserting slot of the placing rod 7, when the moving block 12 moves to the side of the fixed block 11, so that the first magnetic block 17 is magnetically connected with the third magnetic block 19, the inserting rod 22 connected with the moving plate 21 is inserted with the inserting slot outside the placing rod 7 by the moving rod 20, so that the limiting block 14 limits the top of the placing rod 7, and the inserting rod 22 can limit the bottom end of the placing rod 7, thereby improving the stability of the connection between the placing rod 7 and the mounting seat 6, preventing the position deviation of the placing rod 7, and causing the subsequent mechanical hand 4 to place a new blade.

[0044] As shown in Figures 8 to 9 The middle of the placing rod 7 is provided with a groove, and the outer side of the placing rod 7 is provided with a moving port, the moving port is communicated with the groove, the groove is provided with an adjusting structure, the adjusting structure comprises a second motor 24, a rotating rod 25, a movable block 26, a limiting rod, a pushing plate 27, a pushing block 28 and an adjusting block 29, the second motor 24 is fixedly connected to the inner wall top of the groove, the output end of the second motor 24 is fixedly connected with the rotating rod 25, the bottom of the rotating rod 25 is rotatably connected with the inner wall bottom of the groove, the movable block 26 is threadedly connected with the rotating rod 25, the movable block 26 is movably connected with the limiting rod on both sides, the bottom of the movable block is hingedly connected with the pushing plate 27, one end of the pushing plate 27 is hingedly connected with the pushing block 28, one end of the pushing block 28 is hingedly connected with the adjusting block 29, the limiting rod is located in the groove, and the limiting rod is fixedly connected with the inner wall of the groove on the upper and lower sides, the adjusting block 29 is located in the moving port, the adjusting block 29 is arc-shaped, the bottom of the pushing block 28 is slidably connected with the inner wall of the groove, and the bottom of the adjusting block 29 is slidably connected with the top of the mounting seat 6.

[0045] When different sizes of blades need to be placed, the second motor 24 is started to drive the rotating rod 25 to rotate along the inner wall of the groove, the movable block 26 moves downward along the rotating rod 25 under the action of the limiting rod, the pushing plate 27 is deflected, the pushing plate 27 drives the pushing block 28 to move away from one end of the movable block 26, the pushing block 28 pushes the adjusting block 29 to move along the top of the mounting seat 6, the adjusting block 29 moves from the moving port to the outside of the placing rod 7, and since the adjusting block 29 is arc-shaped, different sizes of blades can be placed, the diameter of the placing rod 7 is increased through the adjusting block 29, and different sizes of blades can be adapted, so that the blades are not loose or shaken due to the large size difference between the placing rod 7 and the blades, or the blades are difficult to place or even damaged due to the too tight size, the position precision and overall assembly quality during blade assembly are ensured, and the performance of the final paper shredder product is improved.

[0046] The working principle of the present application is as follows:

[0047] Referring to Figures 1 to 10 As shown, the blade is placed on the guide rail, and the blade is conveyed by the vibration seat and the feeder. When the blade moves to the discharge port of the guide rail, the appearance, quality of the blade is checked by the detection mechanism 3, and the dimensional accuracy is verified. After the detection is completed, the blade gripped by the mechanical hand 4 is placed on the placement rod 7. When the placement rod 7 is full of blades, the first electric push rod 15 is started to drive the moving block 12 to move along the top of the mounting seat 6, so that the moving block 12 drives the two connecting rods 13 on the top to move close to each other. When the connecting rod 13 drives the limiting block 14 to move to the two sides of the blade, the second electric push rod 16 is started to extend, so that the second electric push rod 16 is inserted into the limiting groove of one of the limiting blocks 14, thereby limiting the positions of the two limiting blocks 14, so that the limiting blocks 14 are fixed on the top of the blade. When the first electric push rod 15 drives the moving block 12 to move along the top of the mounting seat 6, so that the moving block 12 drives the first magnetic block 17 to move away from the second magnetic block 18, when the moving block 12 drives the connecting rod 13 and the limiting block 14 to move to the outside of the blade, the first magnetic block 17 at the bottom of the moving block 12 is magnetically connected with the third magnetic block 19, thereby fixing the position of the moving block 12. When the first electric push rod 15 drives the moving block 12 to move along the top of the mounting seat 6, so that the moving block 12 drives the moving rod 20 to move towards the fixed block 11, so that the moving rod 20 pushes the moving plate 21 to move, compresses the compression spring 23, so that the moving plate 21 drives the insertion rod 22 to move towards the insertion groove of the placement rod 7. When the moving block 12 moves to the side of the fixed block 11, so that the first magnetic block 17 is magnetically connected with the third magnetic block 19, the insertion rod 22 connected with the moving plate 21 pushed by the moving rod 20 is inserted into the insertion groove on the outside of the placement rod 7, so that the limiting block 14 limits the top of the placement rod 7. After the blades on the placement rod 7 close to the mounting seat 6 of the mechanical hand 4 are placed, the rotating shaft 9 is driven to rotate by the first motor 10, so that the cam divider 8 is driven to rotate by the rotating shaft 9, thereby enabling the placement rod 7 on one of the mounting seats 6 on the rotating disc 5 to be placed, and enabling the other placement rods 7 without being placed to rotate to the rotating disc 5 close to the mechanical hand 4. The above-mentioned action is repeated to place new blades on the placement rod 7.

[0048] When different sizes of blades need to be placed, the second motor 24 is started to drive the rotating rod 25 to rotate along the inner wall of the groove. Through the action of the limiting rod, the movable block 26 moves downward along the rotating rod 25, and then the push plate 27 is deflected. The push plate 27 drives the push block 28 to move away from one end of the movable block 26, so that the push block 28 pushes the adjusting block 29 to move along the top of the mounting seat 6, so that the adjusting block 29 moves from the moving port to the outside of the placement rod 7. Since the adjusting block 29 is arc-shaped, it can place blades of different sizes. By adjusting the diameter of the placement rod 7 through the adjusting block 29, different sizes of blades can be accommodated, avoiding the situation that the size of the placement rod 7 is too large or too small compared with the size of the blade, causing the blade to be loose or shake during installation, or the size being too tight to cause the blade to be difficult to place or even damaged, etc. The position accuracy and overall assembly quality during blade assembly are ensured, which helps to improve the performance of the final paper shredder product.

[0049] When the placement rods 7 on the four mounting seats 6 are full of blades, the fixed block 11, the moving block 12, the first electric push rod 15, the connecting rod 13 and the limiting block 14 are moved upward, so that the blades between the fixed block 11 and the limiting block 14 can be taken off from the placement rod 7 at the same time, and subsequent operations can be continued.

[0050] The above examples are only used to illustrate the technical solutions of the present application, and are not limiting.
