[0028] First, place the composite material to be processed on the upper side of the workbench 2, put the limit plate on the outer side of the limit rod, and then rotate the nut until the nut, the limit plate and the composite material are tightly against each other, thereby completing the clamping and fixing operation of the composite material, and then select a suitable cutting knife 3, start the controller, and the controller drives the cutting knife 3 to move along the corresponding trajectory by controlling the driving device, thereby completing the edge trimming operation of the composite material. The above are all existing technologies and no unnecessary elaboration is made;

[0029] like Figure 3 , Figure 4 , Figure 6The workbench 2 is equipped with a detection component for the cutting surface of the scrap material after the composite material is cut off. The detection component includes a deep groove 5 opened on the upper side of the workbench 2. The inner wall of the deep groove 5 is fixedly connected to multiple groups of first sensors 7. The deep groove 5 is fixedly connected to an electric push rod 6. The upper side of the electric push rod 6 is slidably connected to a retractable rod 24. Figure 5 , the return rod 24 runs through the electric push rod 6, and from this perspective, the return rod 24 can slide left and right, so as not to affect the movement of the moving plate 8, the upper side of the return rod 24 is fixedly connected to the moving plate 8, and oblique grooves 15 are opened on both sides of the deep groove 5. The two sets of oblique grooves 15 are slidably connected with square blocks 9, and the square blocks 9 and the moving plate 8 are fixedly connected. A rotating groove 10 is opened on the side wall of the moving plate 8, and a threaded ring 16 is rotatably connected in the rotating groove 10. A first gear 17 is fixedly sleeved on the outside of the threaded ring 16, and a first rack 23 is slidably connected in the rotating groove 10. The first rack 23 is meshed with the first gear 17, and a second gear 18 is also fixedly sleeved on the outside of the threaded ring 16. The rotating groove A second rack 20 is slidably connected in the inner part of the 10, and the second rack 20 meshes with the second gear 18. A connecting rod 27 is fixedly connected to the upper side of the second rack 20, and a push plate 11 is fixedly connected to the upper side of the connecting rod 27. A plurality of fixed cylinders 29 are fixedly connected to the side wall of the push plate 11. A moving rod 28 is slidably sleeved in the plurality of fixed cylinders 29. A first spring 30 is fixedly connected between the moving rod 28 and the fixed cylinder 29. A round rod 12 is fixedly connected to the side of the moving rod 28 away from the fixed cylinder 29. A sliding groove 22 is opened on the inner side wall of the deep groove 5. A slide plate 21 is slidably connected in the sliding groove 22. The slide plate 21 is fixedly connected to the first rack 23 to determine and limit the movement trajectory of the first rack 23.

[0030] First, the first sensor 7 is a pressure sensor, which is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to certain rules. Secondly, when the composite material is trimmed, the electric push rod 6 is in a closed state. Although the electric push rod 6 is in a closed state, there is a self-locking structure inside the electric push rod 6, which is common knowledge. Therefore, the electric push rod 6 is in a stationary state at this time, and under the action of the inclined groove 15 and the square block 9, the movable plate 8 is in a stationary state, and the movable plate 8 and the workbench 2 are on the same horizontal line. At this time, since the composite material and the workbench 2 are in a fixed state, and The round rod 12 and the composite material are against each other, and the first spring 30 is in a compressed state. When the composite material needs to be trimmed, the cutting knife 3 is moved downward to perform the trimming operation on the composite material. After the trimming operation is completed, the electric push rod 6 is started, and the electric push rod 6 drives the return rod 24 to move downward. Under the restriction of the inclined groove 15 and the square block 9, the movable plate 8 moves to the lower left along the direction of the inclined groove 15. The scraps of the composite material follow the movable plate 8 into the deep groove 5, and the cutting edge of the scraps is against the first sensor 7. In this process, the movable plate 8 moves to the left relative to the first rack 23, thereby causing the first rack 23 to move downward. The wheel 17 rotates clockwise, the first gear 17 drives the threaded ring 16 and the second gear 18 to rotate clockwise, the second gear 18 drives the second rack 20 to move leftward, the second rack 20 drives the push plate 11 to move leftward through the connecting rod 27 (in this process, only the movement in the horizontal direction is considered), the push plate 11 drives the fixed cylinder 29, the first spring 30 and the moving rod 28 to move leftward, the moving rod 28 drives the round rod 12 to move leftward, the round rod 12 is always against the composite material, the first spring 30 is always in a compressed state, and the compression elastic force of the first spring 30 gradually increases until the scraps are crushed and broken. , and because there is a chamfer on one side of the movable plate 8, the crushed scraps enter the deep groove 5 along the chamfer, thereby completing the collection and processing operation of the scraps, and the scraps left by the trimming follow the movable plate 8 into the deep groove 5. After the scraps and the first sensor 7 collide with each other, the first sensor 7 sends out a corresponding electrical signal. If the electrical signals sent by all the first sensors 7 are the same, it means that the cutting effect of the scraps is good and there is no cutting problem. If the electrical signals sent by all the first sensors 7 are uneven, it means that there are a large number of gaps on the side where the scraps are cut, there are certain cutting problems, and corresponding detection is required.

[0031] like Figure 5 , Figure 7 , Figure 8 , Fig. 9The threaded ring 16 is threadedly sleeved with a threaded barrel 26, and the upper side of the threaded barrel 26 is fixedly connected to the control frame 14. A cleaning component for dust on the surface of the composite material is installed in the control frame 14. The cleaning component includes multiple groups of transmission rods 34 rotatably connected in the control frame 14, and the outer sides of the multiple groups of transmission rods 34 are fixedly sleeved with a fourth gear 35. The control frame 14 is also rotatably connected with multiple groups of intermediate rods 36, and the multiple groups of intermediate rods 36 and the transmission rods 34 are staggered. The outer sides of the multiple groups of intermediate rods 36 are fixedly sleeved with a fifth gear 37, and the fifth gear 37 is meshed with the fourth gear 35. The outer sides of the multiple groups of transmission rods 34 are fixedly connected with a positioning rod 38, and the outer side of the positioning rod 38 is slidably sleeved with a rotating barrel 13, and the rotating barrel 13 and the positioning rod 38 are rotatably sleeved. A second spring 39 is fixedly connected between the rotating cylinder 13 and the positioning rod 38, a second sensor 40 is also fixedly connected between the rotating cylinder 13 and the positioning rod 38, a transmission cylinder 32 is rotatably connected in the control frame 14, a pulley assembly 33 is sleeved between the transmission cylinder 32 and the transmission rod 34, a rotating rod 31 is slidably sleeved on the lower side of the transmission cylinder 32, the rotating rod 31 is rotatably connected to the moving plate 8, a third gear 19 is fixedly sleeved on the outer side of the rotating rod 31, the third gear 19 is meshed with the first gear 17, a square rod 25 is slidably sleeved on the lower side of the threaded cylinder 26, the square rod 25 is fixedly connected to the deep groove 5, the movement trajectory of the threaded cylinder 26 is determined and limited, so that the threaded cylinder 26 can only move up and down relative to the deep groove 5, and the outer wall of the rotating cylinder 13 is smoothly set;

[0032] First, the second sensor 40 is a pressure sensor, which is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to certain rules. Secondly, during the clockwise rotation of the threaded ring 16, under the limiting effect of the square rod 25, the rotation of the threaded ring 16 will cause the threaded barrel 26 to move upward. The threaded barrel 26 drives the control frame 14 to move upward relative to the moving plate 8. At the same time, the movement of the moving plate 8 will also drive the control frame 14 to move leftward. The control frame 14 moves upward relative to the moving plate 8, but the moving plate 8 is Relative to the workbench 2 moving to the lower left, the control frame 14 moves upward and the moving plate 8 moves downward, which eventually causes the control frame 14 to move to the upper left relative to the workbench 2. The control frame 14 moves upward slowly, and in this process, the first gear 17 and the third gear 19 are meshed, the first gear 17 rotating clockwise drives the third gear 19 to rotate counterclockwise, the third gear 19 drives the transmission cylinder 32 to rotate counterclockwise through the rotating rod 31, and the transmission cylinder 32 drives the transmission rod 34 to rotate counterclockwise through the pulley assembly 33. Under the action of the fifth gear 37, all the transmission rods 34 are driven to rotate counterclockwise, and the transmission rods 34 drive the rotating cylinder 13 to rotate around the transmission rod 34. In the process of the rotating cylinder 13 following the control frame 14 to move to the upper left, when the rotating cylinder 13 and the cutting edge of the composite material are abutted, the rotating cylinder 13 will move relative to the positioning rod 38 in the direction close to the transmission rod 34. When the rotating cylinder 13 compresses the second spring 39, the second sensor 40 sends a corresponding electrical signal, and the electrical signal of the second sensor 40 gradually increases. When the rotating cylinder 13 and the cutting edge of the composite material are disconnected, the second sensor 40 sends a corresponding electrical signal. When connected, the rotating cylinder 13 returns to its original position relative to the transmission rod 34, and the second sensor 40 does not send out a signal. If the electrical signals sent out by all the second sensors 40 are consistent, it means that the cutting effect of the composite material is good. If the electrical signals sent out by the first sensor 7 are also consistent, it means that the cutting knife 3 is good. Then, when the control frame 14 continues to move to the upper left, when the rotation of the round rod 12 does not collide with the cutting edge of the composite material, the round rod 12 is located on the upper side of the composite material at this time, and the dust generated after cutting is cleaned to keep the composite material clean, which provides convenience for subsequent processing.

[0033] In the present invention, the composite material to be processed is placed on the upper side of the workbench 2, the limit plate is put on the outer side of the limit rod, and then the nut is rotated until the nut, the limit plate and the composite material are tightly abutted against each other, thereby completing the clamping and fixing operation of the composite material, and then a suitable cutting knife 3 is selected, and the cutting knife 3 is installed in the controller on the upper side of the shell 1, and the controller is started. The controller drives the cutting knife 3 to move along the corresponding trajectory, thereby completing the edge trimming operation of the composite material. The above are all prior arts and no unnecessary details are given. After the edge trimming is completed, the electric push rod 6 is started, and the electric push rod 6 drives the return rod 24 to move downward. Under the limiting action of the inclined groove 15 and the square block 9, the moving rod 28 moves to the lower left direction along the direction of the inclined groove 15. , the scraps of the composite material follow the moving plate 8 into the deep groove 5, and the cutting edge of the scraps is against the first sensor 7. During this process, the moving plate 8 moves leftward relative to the first rack 23, thereby causing the first gear 17 to rotate clockwise, and the first gear 17 drives the threaded ring 16 and the second gear 18 to rotate clockwise, and the second gear 18 drives the second rack 20 to move leftward, and the second rack 20 drives the push plate 11 to move leftward through the connecting rod 27 (in this process, only the movement in the horizontal direction is considered first), the push plate 11 drives the fixed cylinder 29, the first spring 30 and the moving rod 28 to move leftward, and the moving rod 28 drives the round rod 12 to move leftward, the round rod 12 is always against the composite material, the first spring 30 is always in a compressed state, and the first spring The compression elastic force of 30 gradually increases until the scraps are crushed and broken. Since there is a chamfer on one side of the movable plate 8, the broken scraps enter the deep groove 5 along the chamfer, thereby completing the collection and processing operation of the scraps. The scraps left by the trimming follow the movable plate 8 into the deep groove 5. After the scraps and the first sensor 7 collide with each other, the first sensor 7 sends out a corresponding electrical signal. If the electrical signals sent by all the first sensors 7 are the same, it means that the cutting effect of the scraps is good and there is no cutting problem. If the electrical signals sent by all the first sensors 7 are uneven, it means that there are a large number of gaps on the side where the scraps are cut, there are certain cutting problems, and corresponding detection is required. When the threaded ring 16 is rotated clockwise, the first sensor 7 sends out a corresponding electrical signal. During the rotation, under the restriction of the square rod 25, the rotation of the threaded ring 16 will cause the threaded barrel 26 to move upward. The threaded barrel 26 drives the control frame 14 to move upward relative to the moving plate 8. At the same time, the movement of the moving plate 8 will also drive the control frame 14 to move leftward, wherein the control frame 14 moves upward relative to the moving plate 8, but the moving plate 8 moves to the lower left relative to the workbench 2. After the upward movement of the control frame 14 and the downward movement of the moving plate 8 offset each other, the control frame 14 eventually moves to the upper left relative to the workbench 2, wherein the control frame 14 moves upward relatively slowly, and in this process, the first gear 17 and the third gear 19 are meshed, and the clockwise rotating first gear 17 drives the third gear 19 to rotate counterclockwise.The third gear 19 drives the transmission cylinder 32 to rotate counterclockwise through the rotating rod 31, and the transmission cylinder 32 drives the transmission rod 34 to rotate counterclockwise through the pulley assembly 33. Under the action of the intermediate rod 36, the fourth gear 35 and the fifth gear 37, all the transmission rods 34 are driven to rotate counterclockwise, and the transmission rod 34 drives the rotating cylinder 13 to rotate with the transmission rod 34 as the center. In the process of the rotating cylinder 13 following the control frame 14 to move to the upper left, when the rotating cylinder 13 and the cutting edge of the composite material are abutted, the rotating cylinder 13 will move relative to the positioning rod 38 in the direction close to the transmission rod 34. When the rotating cylinder 13 compresses the second spring 39, the second sensor 40 sends a corresponding electrical signal, and the electrical signal of the second sensor 40 gradually increases. When the rotating cylinder 13 and the cutting edge of the composite material are disconnected, the rotating cylinder 13 returns to its original position relative to the transmission rod 34, and the second sensor 40 will not send Signal, if the electrical signals sent by all the second sensors 40 are consistent, it means that the cutting effect of the composite material is good. If the electrical signals sent by the first sensor 7 are also consistent, it means that the cutting blade 3 is good. When the cutting blade 3 cuts the composite material, two cutting surfaces will be formed. If the electrical signals sent by the first sensor 7 and the second sensor 40 are normal, it means that the cutting quality of the cutting blade 3 is good. If the first sensor 7 or the second sensor 40 has an abnormal signal, it means that there is a problem with the cutting blade 3 during the cutting process or there is a problem with the cutting blade 3 itself, and corresponding detection is required. Then, when the control frame 14 continues to move to the upper left, when the rotation of the round rod 12 does not collide with the cutting edge of the composite material, the round rod 12 is located on the upper side of the composite material at this time, and the dust generated after cutting is cleaned to keep the composite material clean, which provides convenience for subsequent processing. ,
