Description

Technical Field

[0001] This invention belongs to the field of fabric cutting technology, and relates to a visual marking and cutting integrated machine, especially a high-precision cantilever visual marking and cutting integrated machine. Background Technology

[0002] A cutting machine is a device that integrates cutting and related auxiliary functions. It is typically used for the precise cutting of various materials such as paper, cloth, plastic, and metal sheets. First, the workpiece is fed into the cutting machine through a material conveying system. The fixing system is adjusted according to the type and size of the material to ensure that the material remains stable during the cutting process. The control system directs the cutting tool system to cut along a predetermined path according to preset cutting parameters. After cutting, the material conveying system will transfer the cut material out of the equipment and may collect and stack it through a collection device.

[0003] Cutting machines have very high precision requirements, mainly due to their wide application in many industries that have extremely high requirements for the size, shape and precision of products.

[0004] Existing high-precision cantilever vision-based line drawing and cutting machines suffer from technical problems such as low cutting accuracy, low cutting efficiency, poor cutting stability, low cutting freedom, and low cutting smoothness.

[0005] Based on this, we propose a high-precision cantilevered vision-based line drawing and cutting integrated machine, which has higher cutting accuracy, higher cutting efficiency, higher cutting stability, higher cutting freedom, and higher cutting smoothness. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a high-precision cantilever-type integrated visual marking and cutting machine. The technical problem to be solved by this invention is: how to achieve higher cutting accuracy, higher cutting efficiency, higher cutting stability, higher cutting freedom, and higher cutting smoothness when cutting workpieces.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A high-precision cantilever-type integrated visual marking and cutting machine includes a conveying mechanism and a horizontal adjustment mechanism. The conveying mechanism is provided with two symmetrically arranged positioning spraying mechanisms, two symmetrically arranged positioning shearing mechanisms, and a cutting frame mechanism arranged sequentially from front to back. The cutting frame mechanism is provided with two symmetrically arranged horizontal adjustment mechanisms. The horizontal adjustment mechanism is located on the two horizontal adjustment mechanisms and is above the conveying mechanism. The horizontal adjustment mechanism is provided with a vertical adjustment mechanism and a cutting tool mechanism. Two symmetrically arranged rolling mechanisms are provided on the lower side of the vertical adjustment mechanism. The cutting tool mechanism is connected to the two rolling mechanisms by transmission.

[0009] The working principle of this invention is as follows: The workpiece to be cut is laid flat on the conveying mechanism. A suitable cutting tool mechanism is selected according to the cutting requirements. At the same time, the working frequency of the left and right positioning spraying mechanisms is set. The conveying mechanism transports the workpiece from front to back. When passing the two positioning spraying mechanisms, the two positioning spraying mechanisms spray and position the corresponding positions on both sides of the workpiece. When the sprayed positioning point passes the two positioning shearing mechanisms, the positioning shearing mechanism detects the sprayed positioning point. The two positioning shearing mechanisms push forward and cut the edges of the corresponding positions on both sides of the workpiece. At the same time, the workpiece is positioned a second time. The cutting accuracy is fed back by the time from spraying positioning to shearing positioning on the same side and the time difference between the two positioning shearing mechanisms detecting the positioning point, and the adjustment is automatic.

[0010] The conveyor mechanism continues to transport the workpiece from front to back. When the cutting frame mechanism detects that the workpiece has reached the corresponding position directly below it, the conveyor mechanism stops transporting, and the cutting frame mechanism presses down, pressing the workpiece within its area against the conveyor mechanism to improve cutting stability and reduce cutting errors. Simultaneously, the horizontal adjustment mechanism and two transverse adjustment mechanisms drive the vertical adjustment mechanism to move to one of the edge cutting positions. The vertical adjustment mechanism then drives the cutting tool mechanism and two rolling mechanisms to descend until the cutting tool mechanism reaches the cutting position. According to a pre-set program, the horizontal adjustment mechanism... In conjunction with two lateral adjustment mechanisms, the cutting tool mechanism and two rolling mechanisms are driven to cut the workpiece within the cutting frame mechanism area. During the cutting process, the two rolling mechanisms press the workpiece near the cutting tool mechanism to avoid cutting errors caused by elastic pulling or displacement of the workpiece due to shearing force. At the same time, during the cutting process, as the horizontal adjustment mechanism and the two lateral adjustment mechanisms drive the two rolling mechanisms to move, the rolling mechanisms automatically adjust according to the direction of movement, and drive the direction of the cutting tool mechanism to adjust synchronously through the gear pair, thereby improving the cutting smoothness and cutting accuracy.

[0011] The conveying mechanism includes a conveyor frame, with conveyor rollers rotatably mounted at both ends of the conveyor frame, and a conveyor belt rotatably mounted between the two conveyor rollers. A conveyor motor is fixed inside the conveyor frame, and the output shaft of the conveyor motor is connected to one of the conveyor rollers via a sprocket drive. Support side plates are fixed on both the left and right sides of the conveyor frame. A set of lifting slide plates is fixed at the upper end of both the left and right sides of the conveyor frame. Each set contains two lifting slide plates, and the positions of the two sets of lifting slide plates correspond to each other. Two lifting push rods are fixed at the upper end of the conveyor frame, and the two lifting push rods are respectively located between a set of lifting slide plates on the same side.

[0012] With the above structure, the conveyor belt is used to place the workpiece to be cut. The output shaft of the conveyor motor rotates, which drives one of the conveyor rollers to rotate, causing the conveyor belt to rotate from front to back, thereby moving the workpiece to be cut from front to back.

[0013] The cutting frame mechanism includes four I-beam frames and two connecting seats. A vision sensor is fixed to the lower side of one of the I-beam frames. The four I-beam frames form a rectangular frame. The left and right I-beam frames are fixed to the upper end of the push rod of the corresponding lifting push rod. Adjacent I-beam frames are connected by connectors. The connectors are slidably set on the lifting slide plate at the corresponding position. Several sliding adjustment blocks are slidably provided on each I-beam frame. The sliding adjustment blocks are connected to the corresponding connecting seats by several compression spring rods. A vertical support frame is fixed to the lower side of the connecting seat. A rubber pad is fixed to the lower side of the vertical support frame.

[0014] Using the above structure, the position of the sliding adjustment block is adjusted according to the size of the workpiece. When the vision sensor detects that the workpiece has reached the corresponding position directly below the I-shaped frame, the output shaft of the conveyor motor stops rotating, causing the workpiece to stop moving. The output shaft of the lifting push rod rotates, causing the sliding adjustment block to slide downwards, which in turn causes the four rubber pads to descend. Thus, through several compression spring rods, the workpiece in the rectangular frame is pressed against the conveyor belt.

[0015] The lateral adjustment mechanism includes a lead screw motor and a lead screw. The lead screw motor is fixed on a connecting piece at a corresponding position, and the lead screw is rotatably mounted on the connecting piece at a corresponding position. The output shaft of the lead screw motor is connected to the lead screw. The lead screws of the two lateral adjustment mechanisms are horizontally arranged and parallel to each other.

[0016] With the above structure, during operation, the output shafts of the two lead screw motors rotate synchronously, driving the two lead screws to rotate synchronously.

[0017] The horizontal adjustment mechanism includes two transmission seats, which are driven on lead screws at corresponding positions. Two slide rods are fixed between the two transmission seats. A lead screw motor is fixed to the outside of one of the transmission seats. The output shaft of the lead screw motor passes through the transmission seat. At the same time, a lead screw is fixed on the output shaft of the lead screw motor. The lead screw is rotatably disposed inside the two transmission seats and is parallel to the two slide rods.

[0018] With the above structure, the two lead screws rotate synchronously, driving the two transmission seats to slide synchronously, thereby adjusting the horizontal position of the cutting tool mechanism. The output shaft of the lead screw motor rotates, driving the lead screw to rotate.

[0019] The vertical adjustment mechanism includes a vertical lead screw, which is driven on a second lead screw and slidably mounted on two slide rods. A cutting sliding seat is driven on the vertical lead screw.

[0020] With the above structure, the second lead screw rotates, driving the vertical lead screw component to move left and right, and the cutting sliding seat moves vertically on the vertical lead screw component.

[0021] The cutting tool mechanism includes a tool holder, a counterweight fixed on the upper side of the tool holder, a rotating seat rotatably provided on the lower side of the tool holder, and a cutting tool detachably provided on the rotating seat detachably.

[0022] The tail pressure roller mechanism includes a hinged seat, which is rotatably connected to the tool holder by bolts, and a follow-pressure roller is rotatably provided on the lower side of the hinged seat.

[0023] Using the above structure, a suitable cutting blade is selected according to the cutting requirements. The cutting blade is used to cut the workpiece. The rotating seat adjusts the direction of the cutting blade according to the cutting trajectory. The counterweight seat is used to increase the overall weight of the cutting tool mechanism and improve the cutting stability.

[0024] The hinged seat drives the pressure roller. When the rotating seat adjusts the direction of the cutting blade according to the cutting trajectory, the pressure roller adjusts synchronously with the direction of the cutting blade. Due to gravity, the pressure roller always keeps close to the cut surface of the workpiece, improving the stability during cutting and reducing the error caused by the workpiece being cut and easily moving at the cut surface.

[0025] The rolling mechanism includes a second rotating seat, which is connected to the first rotating seat by a gear pair. The second rotating seat is rotatably mounted on the lower side of the cutting sliding seat, and a roller is rotatably mounted on the second rotating seat. A rubber tire is fixed to the outer side of the roller.

[0026] With the above structure, the vertical lead screw drives the cutting sliding seat to slide downwards, so that the rubber tires press the workpiece firmly against the conveyor belt, making the cutting of the workpiece more stable in the area between the two rubber tires. When the horizontal adjustment mechanism and the two transverse adjustment mechanisms drive the vertical adjustment mechanism to move horizontally, they drive the two rollers to roll on the workpiece. When rolling, the two rollers rotate synchronously on the rotating seat two according to the rolling direction, and at the same time drive the rotating seat one to rotate synchronously through the gear pair, thereby driving the cutting blade to face the cutting direction and improving the stability during cutting.

[0027] The positioning and shearing mechanism includes a positioning and shearing motor, which is slidably mounted on a support side plate at a corresponding position. A second vision sensor is fixed inside the positioning and shearing motor, and a positioning and shearing blade is driven on the output shaft of the positioning and shearing motor.

[0028] With the above structure, when the vision sensor 2 detects the positioning point of the spraying, the positioning shear motor slides forward, and at the same time, the output shaft of the positioning shear motor rotates, controlling the positioning shear blade to perform a shearing action to cut the edge of the workpiece. After the shearing is completed, the positioning shear motor resets.

[0029] The positioning and spraying mechanism includes a Z-shaped fixed base, which is fixed on the upper side of the conveyor frame. A spraying motor is fixed on the upper side of the Z-shaped fixed base, and a spraying component is fixed on the lower side of the Z-shaped fixed base. The spraying component is connected to the paint storage tank, and the spraying motor is electrically connected to the spraying component.

[0030] Using the above structure, the operating frequencies of the left and right spraying motors are set according to the cutting requirements, and the spraying motors control the spraying parts to spray and position them at the corresponding positions on the workpiece.

[0031] Compared with existing technologies, this high-precision cantilever-type vision marking and cutting integrated machine has the following advantages:

[0032] 1. By cooperating with the conveying mechanism and the positioning spraying mechanism, the workpiece to be cut is first sprayed and positioned, resulting in higher cutting accuracy;

[0033] 2. By cooperating with the conveying mechanism and the positioning and shearing mechanism, a second spraying and positioning of the workpiece to be cut is achieved, resulting in higher cutting accuracy. At the same time, pre-cutting is performed at both ends of the cutting trajectory to improve cutting efficiency.

[0034] 3. By cooperating with the conveying mechanism and the cutting frame mechanism, the workpieces in the area of ​​the cutting frame mechanism are pressed against the conveying mechanism, which improves cutting stability and reduces cutting error;

[0035] 4. By cooperating with the positioning spraying mechanism and the positioning shearing mechanism, the cutting accuracy is fed back by the time from spraying positioning to shearing positioning on the same side, as well as the time difference between the two positioning shearing mechanisms detecting the positioning point, and the cutting accuracy is improved by automatic adjustment.

[0036] 5. By cooperating with the vertical adjustment mechanism, the horizontal adjustment mechanism and two transverse adjustment mechanisms, the cutting tool mechanism can cut the workpiece according to the preset trajectory, thus achieving a higher degree of cutting freedom;

[0037] 6. By driving the cutting tool mechanism to cooperate with two rolling mechanisms, the two rolling mechanisms press the workpiece near the cutting tool mechanism. At the same time, the rolling mechanism automatically adjusts according to the direction of movement, and drives the cutting tool mechanism to adjust its direction synchronously through the gear pair, thereby improving the cutting smoothness and cutting accuracy.

[0046] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0047] like Figures 1-5 As shown, this high-precision cantilever visual marking and cutting integrated machine includes a conveying mechanism 1 and a horizontal adjustment mechanism 4. The conveying mechanism 1 is provided with two left-right symmetrical positioning spraying mechanisms 9, two left-right symmetrical positioning cutting mechanisms 8, and a cutting frame mechanism 2 arranged sequentially from front to back. The cutting frame mechanism 2 is provided with two left-right symmetrical horizontal adjustment mechanisms 3. The horizontal adjustment mechanism 4 is arranged on the two horizontal adjustment mechanisms 3 and is located above the conveying mechanism 1. The horizontal adjustment mechanism 4 is provided with a vertical adjustment mechanism 5. The vertical adjustment mechanism 5 is provided with a cutting tool mechanism 6. The lower side of the vertical adjustment mechanism 5 is provided with two left-right symmetrical rolling mechanisms 7. The cutting tool mechanism 6 is connected to the two rolling mechanisms 7 by transmission.

[0048] In this embodiment, the workpiece to be cut is laid flat on the conveying mechanism 1. A suitable cutting tool mechanism 6 is selected according to the cutting requirements. At the same time, the working frequency of the left and right positioning spraying mechanisms 9 is set. The conveying mechanism 1 transports the workpiece from front to back. When passing the two positioning spraying mechanisms 9, the two positioning spraying mechanisms 9 spray and position the corresponding positions on both sides of the workpiece. When the sprayed positioning point passes the two positioning shearing mechanisms 8, the positioning shearing mechanism 8 detects the sprayed positioning point, and the two positioning shearing mechanisms 8 push forward and cut the edges of the corresponding positions on both sides of the workpiece. At the same time, the workpiece is positioned a second time. The cutting accuracy is fed back by the time from spraying positioning to shearing positioning on the same side and the time difference between the two positioning shearing mechanisms 8 detecting the positioning point, and the cutting accuracy is automatically adjusted.

[0049] The conveying mechanism 1 continues to transport the workpiece from front to back. When the cutting frame mechanism 2 detects that the workpiece has reached the corresponding position directly below the cutting frame mechanism 2, the conveying mechanism 1 stops transporting, and the cutting frame mechanism 2 presses down, pressing the workpiece within the area of ​​the cutting frame mechanism 2 against the conveying mechanism 1, improving cutting stability and reducing cutting errors. At the same time, the horizontal adjustment mechanism 4 and the two transverse adjustment mechanisms 3 drive the vertical adjustment mechanism 5 to move to one of the edge cutting positions. The vertical adjustment mechanism 5 drives the cutting tool mechanism 6 and the two rolling mechanisms 7 to descend until the cutting tool mechanism 6 reaches the inside of the cutting position. According to the pre-set program, the horizontal adjustment mechanism... The mechanism 4 and two lateral adjustment mechanisms 3 work together to drive the cutting tool mechanism 6 and two rolling mechanisms 7 to cut the workpiece in the area of ​​the cutting frame mechanism 2. During the cutting process, the two rolling mechanisms 7 press the workpiece near the cutting tool mechanism 6 to avoid cutting errors caused by elastic pulling or displacement of the workpiece due to shearing force. At the same time, during the cutting process, as the horizontal adjustment mechanism 4 and the two lateral adjustment mechanisms 3 drive the two rolling mechanisms 7 to move, the rolling mechanisms 7 automatically adjust according to the direction of movement, and drive the direction of the cutting tool mechanism 6 to adjust synchronously through the gear pair, thereby improving the cutting smoothness and cutting accuracy.

[0050] The conveying mechanism 1 includes a conveyor frame 101. Conveying rollers 107 are rotatably mounted at both ends of the conveyor frame 101. A conveyor belt 102 is rotatably mounted between the two conveying rollers 107. A conveyor motor 103 is fixed inside the conveyor frame 101. The output shaft of the conveyor motor 103 is connected to one of the conveying rollers 107 via a sprocket drive. Support side plates 104 are fixed on both the left and right sides of the conveyor frame 101. A set of lifting slide plates 105 is fixed at the upper end of both the left and right sides of the conveyor frame 101. There are two lifting slide plates 105 in each set. The positions of the two sets of lifting slide plates 105 correspond to each other. A lifting push rod 106 is fixed between each set of lifting slide plates 105. The lifting push rod 106 is mounted on the conveyor frame 101.

[0051] In this embodiment, the conveyor belt 102 is used to place the workpiece to be cut. The output shaft of the conveyor motor 103 rotates, driving one of the conveyor rollers 107 to rotate, which in turn drives the conveyor belt 102 to rotate from front to back, thereby moving the workpiece to be cut from front to back.

[0052] The cutting frame mechanism 2 includes four I-beam frames 201 and several connecting seats 207. A vision sensor is fixed to the lower side of one of the I-beam frames 201. The four I-beam frames 201 form a rectangular frame. The left and right I-beam frames 201 are fixed to the upper end of the push rod of the lifting push rod 106 at the corresponding position. The two adjacent I-beam frames 201 are connected by a connector 202. The connector 202 is slidably set on the lifting slide plate 105 at the corresponding position. Several sliding adjustment blocks 205 are slidably provided on each I-beam frame 201. The sliding adjustment blocks 205 are connected to the connecting seats 207 at the corresponding position by several compression spring rods 206. A vertical support frame 203 is fixed to the lower side of the connecting seat 207. A rubber pad 204 is fixed to the lower side of the vertical support frame 203.

[0053] In this embodiment, the position of the sliding adjustment block 205 is adjusted according to the size of the workpiece. When the vision sensor detects that the workpiece has reached the corresponding position directly below the I-shaped frame 201, the output shaft of the conveyor motor 103 stops rotating, causing the workpiece to be cut to stop moving. The output shaft of the lifting push rod 106 rotates, causing the sliding adjustment block 205 to slide downward, causing the four rubber pads 204 to descend, thereby pressing the workpiece in the rectangular frame against the conveyor belt 102 through several compression spring rods 206.

[0054] The lateral adjustment mechanism 3 includes a lead screw motor 301 and a lead screw 302. The lead screw motor 301 is fixed on the connecting piece 202 at the corresponding position, and the lead screw 302 is rotatably mounted on the connecting piece 202 at the corresponding position. The output shaft of the lead screw motor 301 is connected to the lead screw 302 in a transmission connection. The lead screws 302 of the two lateral adjustment mechanisms 3 are arranged horizontally and parallel to each other.

[0055] In this embodiment, during operation, the output shafts of the two lead screw motors 301 rotate synchronously, driving the two lead screws 302 to rotate synchronously.

[0056] The horizontal adjustment mechanism 4 includes two transmission seats, which are driven on lead screws 302 at corresponding positions. Two slide rods 403 are fixed between the two transmission seats. A lead screw motor 402 is fixed to the outside of one of the transmission seats. The output shaft of the lead screw motor 402 passes through the transmission seat. At the same time, a lead screw 401 is fixed on the output shaft of the lead screw motor 402. The lead screw 401 is rotatably disposed inside the two transmission seats and is arranged parallel to the two slide rods 403.

[0057] In this embodiment, the two lead screws 302 rotate synchronously, driving the two transmission seats to slide synchronously, thereby adjusting the horizontal position of the cutting tool mechanism 6. The output shaft of the lead screw motor 402 rotates, driving the lead screw 401 to rotate.

[0058] The vertical adjustment mechanism 5 includes a vertical lead screw 501, which is driven on a second lead screw 401 and slidably mounted on two slide rods 403. A cutting slide seat 502 is driven on the vertical lead screw 501.

[0059] In this embodiment, the second lead screw 401 rotates, causing the vertical lead screw 501 to move left and right, and the cutting sliding seat 502 moves vertically on the vertical lead screw 501.

[0060] The cutting tool mechanism 6 includes a tool holder 602, a counterweight 601 fixed on the upper side of the tool holder 602, a rotating seat 603 rotatably provided on the lower side of the tool holder 602, and a cutting tool 604 detachably provided on the rotating seat 603.

[0061] The tail pressure roller mechanism 10 includes a hinge seat 1001, which is rotatably connected to the tool holder 602 by bolts. The lower side of the hinge seat 1001 is rotatably provided with a follow pressure roller 1002.

[0062] In this embodiment, a suitable cutting blade 604 is selected according to the cutting requirements. The cutting blade 604 is used to cut the workpiece. The rotating seat 603 adjusts the direction of the cutting blade 604 according to the cutting trajectory. The counterweight seat 601 is used to increase the overall weight of the cutting tool mechanism 6 and improve the cutting stability.

[0063] The hinge seat 1001 drives the pressure roller 1002. When the rotating seat 603 adjusts the direction of the cutting blade 604 according to the cutting trajectory, the pressure roller 1002 adjusts synchronously with the direction of the cutting blade 604. Due to gravity, the pressure roller 1002 always keeps tightly against the cut surface of the workpiece, improving the stability during cutting and reducing the error caused by the workpiece being cut and the easy movement of the cut surface.

[0064] The rolling mechanism 7 includes a second rotating seat 703, which is connected to the first rotating seat 603 by a gear pair. The second rotating seat 703 is rotatably mounted on the lower side of the cutting sliding seat 502. A roller 701 is rotatably mounted on the second rotating seat 703, and a rubber tire 702 is fixed on the outer side of the roller 701.

[0065] In this embodiment, the vertical lead screw 501 drives the cutting sliding seat 502 to slide downward, so that the rubber outer tire 702 presses the workpiece against the conveyor belt 102, making the cutting of the workpiece more stable in the area between the two rubber outer tires 702. When the horizontal adjustment mechanism 4 and the two transverse adjustment mechanisms 3 drive the vertical adjustment mechanism 5 to move horizontally, they drive the two rollers 701 to roll on the workpiece. When rolling, the two rollers 701 rotate synchronously on the rotating seat 703 according to the rolling direction. At the same time, the rotating seat 603 is driven to rotate synchronously through the gear pair, thereby driving the cutting blade 604 to face the cutting direction, improving the stability during cutting.

[0066] The positioning shearing mechanism 8 includes a positioning shearing motor 801, which is slidably mounted on the support side plate 104 at the corresponding position. A second vision sensor is fixed inside the positioning shearing motor 801, and a positioning shearing blade 802 is driven on the output shaft of the positioning shearing motor 801.

[0067] In this embodiment, when the vision sensor 2 detects the positioning point of the spraying, the positioning shear motor 801 slides forward, and at the same time, the output shaft of the positioning shear motor 801 rotates, controlling the positioning shear blade 802 to perform a shearing action to shear the edge of the workpiece. After the shearing is completed, the positioning shear motor 801 resets.

[0068] The positioning spraying mechanism 9 includes a Z-shaped fixing seat 901, which is fixed on the upper side of the conveyor frame 101. A spraying motor 902 is fixed on the upper side of the Z-shaped fixing seat 901, and a spraying component 903 is fixed on the lower side of the Z-shaped fixing seat 901. The spraying component 903 is connected to the paint storage tank, and the spraying motor 902 is electrically connected to the spraying component 903.

[0069] In this embodiment, the operating frequencies of the left and right spraying motors 902 are set according to the cutting requirements, and the spraying motors 902 control the spraying part 903 to spray and position the workpiece at the corresponding position.

[0070] The working principle of this invention is as follows: Select a suitable cutting tool mechanism 6 according to the cutting requirements, and at the same time set the working frequency of the left and right spraying motors 902 respectively;

[0071] The workpiece to be cut is laid flat on the conveyor belt 102. The output shaft of the conveyor motor 103 rotates, driving one of the conveyor rollers 107 to rotate, which in turn drives the conveyor belt 102 to rotate from front to back, thereby moving the workpiece to be cut from front to back. The spraying motor 902 controls the spraying part 903 to spray and position the workpiece at the corresponding position. When the vision sensor 2 detects the spraying positioning point, the positioning shearing motor 801 slides forward, and at the same time, the output shaft of the positioning shearing motor 801 rotates, controlling the positioning shearing blade 802 to perform a shearing action to cut the edge of the workpiece. After the shearing is completed, the positioning shearing motor 801 resets, thus realizing the cutting of the workpiece. The second positioning, based on the time from spraying positioning to shearing positioning on the same side, and the time difference between the two vision sensors detecting the positioning point, provides feedback on the cutting accuracy and automatically adjusts it. When vision sensor one detects that the workpiece has reached the corresponding position directly below the I-beam frame 201, the output shaft of the conveyor motor 103 stops rotating, causing the workpiece to stop moving. The output shaft of the lifting push rod 106 rotates, causing the corresponding connecting piece 202 to slide downwards, which in turn causes the four rubber pads 204 to descend. This, through several compression spring rods 206, presses the workpiece within the rectangular frame against the conveyor belt 102. Simultaneously, the output shafts of the two lead screw motors 301... The output shaft rotates synchronously, driving the two lead screws 302 to rotate synchronously, which in turn drives the two transmission seats to slide synchronously, thereby adjusting the horizontal position of the cutting tool mechanism 6. The output shaft of the lead screw motor 402 rotates, driving the lead screw 401 to rotate, which in turn drives the vertical lead screw 501 to move left and right, moving the cutting sliding seat 502 to one of the edge cutting positions. The vertical lead screw 501 drives the cutting sliding seat 502 to slide downward, so that the rubber tire 702 presses the workpiece against the conveyor belt 102, making the cutting of the workpiece more stable in the area between the two rubber tires 702. The horizontal adjustment mechanism 4 and the two transverse adjustment mechanisms 3 drive the vertical adjustment mechanism. 5. During horizontal movement, the two rollers 701 are driven to roll on the workpiece. When rolling, the two rollers 701 rotate synchronously on the rotating seat 703 according to the rolling direction. At the same time, the rotating seat 603 is driven to rotate synchronously through the gear pair, thereby driving the cutting blade 604 to face the cutting direction, improving the stability during cutting. The hinge seat 1001 drives the pressure roller 1002. When the rotating seat 603 adjusts the direction of the cutting blade 604 according to the cutting trajectory, the pressure roller 1002 adjusts synchronously with the direction of the cutting blade 604. Due to gravity, the pressure roller 1002 is always tightly attached to the cut edge of the workpiece, improving the stability during cutting.

[0072] In summary, by cooperating with the conveying mechanism 1 and the positioning spraying mechanism 9, the workpiece to be cut is positioned by the first spraying, which makes the cutting accuracy higher.

[0073] By cooperating with the conveying mechanism 1 and the positioning and shearing mechanism 8, the workpiece to be cut is positioned by a second spray coating, resulting in higher cutting accuracy. At the same time, the ends of both sides of the cutting trajectory are pre-cut to improve cutting efficiency.

[0074] By cooperating with the cutting frame mechanism 2, the workpieces in the area of ​​the cutting frame mechanism 2 are pressed against the conveying mechanism 1, thereby improving cutting stability and reducing cutting error.

[0075] By cooperating with the positioning spraying mechanism 9 and the positioning shearing mechanism 8, the cutting accuracy is fed back by the time from spraying positioning to shearing positioning on the same side, and the time difference between the two positioning shearing mechanisms 8 detecting the positioning point, and the cutting accuracy is improved by automatic adjustment.

[0076] By cooperating with the vertical adjustment mechanism 5, the horizontal adjustment mechanism 4 and the two transverse adjustment mechanisms 3, the cutting tool mechanism 6 can cut the workpiece according to the preset trajectory, thus achieving a higher degree of cutting freedom.

[0077] By driving the cutting tool mechanism 6 to cooperate with the two rolling mechanisms 7, the two rolling mechanisms 7 press the workpiece near the cutting tool mechanism 6. At the same time, the rolling mechanism 7 automatically adjusts according to the direction of movement, and drives the cutting tool mechanism 6 to adjust the direction synchronously through the gear pair, thereby improving the cutting smoothness and cutting accuracy.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
