Description

Technical Field

[0001] This invention relates to the field of CNC blade cutting technology, specifically to an intelligent positioning aluminum plate cutting device. Background Technology

[0002] Aluminum sheet cutting equipment is a processing tool used for cutting aluminum sheets to a fixed length, blanking, and contouring. This type of equipment typically uses a CNC system to precisely control the cutting path, feed rate, and cutting parameters, and works with blades to continuously cut the aluminum sheet, thereby achieving efficient processing of the sheet material.

[0003] In the continuous cutting process, existing cutting equipment often requires operators to observe the quality of the cut surface in real time to detect abnormalities such as burrs, excessive saw marks, and rough cut surfaces in a timely manner, so as to avoid the continuous production of defective products. This not only increases the reliance on manual labor and labor intensity, but also makes it difficult to guarantee the stability and accuracy of long-term continuous monitoring. Even if some equipment is equipped with imaging detection devices, it usually requires segment-by-segment imaging scanning of the cutting area, which takes a long time and has low overall imaging efficiency. In addition, coolant and debris often remain at the cutting point, which can easily interfere with the image clarity and lead to misjudgment or missed judgment. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent positioning aluminum plate cutting device to solve the problem of lack of efficient quality control in the cutting process in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent positioning aluminum plate cutting device, comprising a cutting table and a pre-inspection and seam cleaning device, wherein a cutting device is installed inside the cutting table, a positioning frame is installed on the cutting table, and a fixing mechanism is installed on the cutting table;

[0006] The pre-inspection and cleaning device includes an expansion absorber, an upper slide rail, and a lower slide rail. The upper slide rail is installed on the top of the cutting table surface, and an upper detection slide is slidably mounted on the upper slide rail. A dehydration mechanism is installed on the upper detection slide. The lower slide rail is installed at the bottom of the cutting table surface, and a lower detection slide is slidably mounted on the lower slide. A diameter adjustment mechanism is installed on the lower detection slide. The top of the expansion absorber is rotatably connected to the dehydration mechanism, and the bottom of the expansion absorber is connected to the diameter adjustment mechanism. An air inflation device is installed on the dehydration mechanism.

[0007] The cutting equipment is equipped with a control system that controls the entire process. A positioning frame abuts against the perimeter of the aluminum plate to be cut, limiting its movement. The fixing mechanism consists of a cylinder and a positioning plate; the cylinder's output shaft drives the positioning plate to press against the aluminum plate, thus fixing it in place.

[0008] Both the upper and lower slide rails are electric slide rail structures, which can drive the upper detection slide and the lower detection slide respectively.

[0009] During operation, the aluminum plate is first placed in the positioning frame, and the control system activates the fixing mechanism to secure the aluminum plate. Then, the control system activates the cutting device, and the lifting mechanism drives the electric cutting machine to rise and fall. After the blade is positioned, the sliding table drives the electric cutting machine to move along the cutting edge while cutting the aluminum plate.

[0010] Furthermore, the upper detection slide includes a slider, which is slidably mounted on the upper slide rail. A connecting slide head is slidably mounted on the slider, and a dehydration mechanism is mounted on the connecting slide head. A piezoelectric element is installed inside the slider, and a pad is slidably mounted inside the slider. The pad is in close contact with the piezoelectric element. A lever is mounted on the connecting slide head, and an elastic element is installed between the lever and the pad.

[0011] The upper and lower detection slides have the same structure. The piezoelectric element is connected to the control system. The elastic element is a spring.

[0012] After cutting, the control system activates the upper and lower slide rails, causing the upper and lower detection slides to move synchronously and at a uniform speed along the cutting seam. The upper detection slide drives the dehydration mechanism, while the lower detection slide drives the diameter adjustment mechanism. The dehydration and diameter adjustment mechanisms work together to move the expansion and suction unit along the cutting seam. During this movement, the expansion and suction unit uses its external suction sleeve to absorb residual coolant within the cutting seam and pushes away debris adhering to the cut surface, thus completing the dehydration and seam cleaning process.

[0013] When the cut surface is relatively flat and smooth, the contact resistance encountered by the expansion and water absorption component is small and the resistance is relatively stable during the movement along the cut seam. The liquid removal mechanism and the diameter adjustment mechanism can drive the expansion and water absorption component to maintain stable movement.

[0014] When the cut surface has burrs, excessive roughness in certain areas, heavy saw marks, or other cutting abnormalities, the contact resistance between the expansion absorber and the cut surface will increase significantly when the expansion absorber passes through the corresponding area, resulting in localized obstruction. This obstruction causes a relative lag in the expansion absorber's movement, pulling on the liquid removal and diameter adjustment mechanisms, and further causing relative displacement between the connecting slider and the uniformly moving drive slider. During this relative displacement, the connecting slider pushes the paddle to compress the elastic element. After compression, the elastic element applies pressure to the piezoelectric element via the pad, and the piezoelectric element outputs an electrical signal corresponding to the magnitude of the pressure. The more severe the cut surface problem, the greater the resistance experienced by the expansion absorber in the corresponding area, the more pronounced the relative displacement between the connecting slider and the drive slider, and the higher the intensity of the electrical signal output by the piezoelectric element.

[0015] The control system makes a preliminary judgment on the quality of the cut surface based on the strength of the electrical signal output by the piezoelectric element: when the electrical signal is within the set standard range, the cutting quality of that area is considered normal; when the electrical signal is higher than the standard value, the corresponding area is considered to have a cutting abnormality. At the same time, the continuous electrical signal generated by the expansion and water absorption component moving along the entire cut seam can form a corresponding detection signal curve. The control system then matches this signal curve with the length of the board material to locate the problematic area of ​​the board material corresponding to the abnormal fluctuation.

[0016] When the inspection results indicate the presence of abnormal areas, the control system activates an external material transfer device to move the cut sheet metal to the industrial camera inspection station. The system then controls the industrial camera to perform targeted imaging inspection of the identified non-conforming areas to further identify the specific defect types and analyze their causes. Since the expansion absorbent component has already completed the removal of residual liquid and debris from the cut surface during the pre-inspection process, interference from factors such as coolant reflection and debris obstruction on the imaging field of view can be avoided, thereby reducing the probability of misjudgment and improving imaging inspection accuracy.

[0017] If no abnormalities are found in the pre-inspection results, there is no need to use an industrial camera to scan the entire cut section segment by segment, and continuous cutting can be carried out directly. Thus, the purpose of cleaning the cutting seam and pre-inspecting the section is achieved simultaneously through the expansion water absorption component; by pre-positioning the abnormal area, the invalid scanning range of the industrial camera can be reduced, the overall inspection time can be shortened, and the continuity of aluminum plate cutting production and inspection efficiency can be improved while ensuring the accuracy of cutting quality judgment.

[0018] Furthermore, the desliming mechanism includes a desliming shell, an air inflator installed on the desliming shell, the air inflator connected to a connecting slide head, an air inflator installed on the air inflator, an air inflator plate installed inside the desliming shell, and the air inflator rotatably connected to the expansion water absorption component.

[0019] Furthermore, the dehydration shell is provided with a gas channel and an annular cavity. The inflation plate is located in the annular cavity. One end of the gas channel is connected to the inflation connector, and the other end of the gas channel is connected to the inflation plate.

[0020] The inflation device can extract or release gas, and is used to fill or extract gas into the inflation plate through the inflation connector and gas channel.

[0021] Furthermore, the inflatable plate has a hollow cavity, and several exhaust holes are provided on one side of the hollow cavity. The hollow cavity is connected to the gas channel.

[0022] After the crack cleaning and inspection operation is completed, the control system starts the inflation device. The inflation device alternately inflates and deflates the inflation plate through the inflation connector and gas channel. During inflation, the gas first enters the hollow cavity, and then enters the main cavity through the exhaust hole on one side of the hollow cavity, increasing the air pressure in the main cavity and pushing the rotating plate to deflect towards the secondary cavity. During this process, the volume of the main cavity increases, the volume of the secondary cavity decreases, and the air in the secondary cavity is discharged through the adjustment hole. During deflation, the inflation device draws the gas out of the main cavity through the inflation plate, causing the main cavity to contract and the air pressure to decrease. The secondary cavity expands accordingly, and external air enters the secondary cavity through the adjustment hole. Under the action of the pressure difference, the rotating plate deflects in the opposite direction to the main cavity and returns to its original position.

[0023] By alternating inflation and deflation, the rotating plate continuously oscillates back and forth, causing the rotary joint to deflect back and forth within the annular cavity. The rotary joint further drives the top of the absorbent sleeve to rotate back and forth. Since the bottom of the absorbent sleeve is fixed, the entire absorbent sleeve twists back and forth as the top deflects, thereby squeezing out the liquid adsorbed inside the absorbent sleeve. This achieves the wringing out process of the absorbent sleeve, allowing it to regain its liquid absorption capacity without disassembly, thus meeting the operational requirements of continuous crack cleaning and inspection.

[0024] Furthermore, the expansion suction component includes an expansion tube, the top end of which is connected to the desiccant shell, the bottom end of which is connected to the diameter adjustment mechanism, a suction sleeve is fitted on the expansion tube, a rotary joint is connected to the top end of the suction sleeve, the rotary joint is rotatably installed inside the desiccant shell, and a fixed joint is connected to the bottom end of the suction sleeve, the fixed joint is installed inside the diameter adjustment mechanism.

[0025] The expansion tube is made of a flexible, expandable material; the absorbent sleeve is made of a flexible, absorbent material. The expansion tube can be a rubber tube, and the absorbent sleeve can be an absorbent cotton sleeve. The absorbent sleeve expands along with the expansion tube and absorbs the coolant.

[0026] Furthermore, the diameter adjustment mechanism includes a diameter adjustment shell, which is installed on the lower detection slide. A connecting channel is provided inside the diameter adjustment shell, and a bladder is installed inside the diameter adjustment shell. The top end of the connecting channel is connected to the expansion tube, and the bottom end of the connecting channel is connected to the bladder. A telescopic rod is installed inside the diameter adjustment shell, and a compression plate is installed on the output shaft of the telescopic rod. The compression plate is in close contact with the bladder.

[0027] Before the seam cleaning and inspection operation, the control system activates the telescopic rod. The output shaft of the telescopic rod drives the extrusion plate to move, applying pressure to the bladder. After being compressed, the gas inside the bladder is transported to the expansion tube through the connecting channel, causing the expansion tube to expand. The control system can adjust the extension of the telescopic rod's output shaft according to the size of the cut seam, thereby controlling the degree of extrusion of the bladder by the extrusion plate, and thus controlling the amount of gas entering the expansion tube and the degree of expansion of the expansion tube. This allows the expansion tube to drive the absorbent sleeve to expand to a size that matches the cut seam gap, thus achieving adaptive adjustment of the diameter of the expansion absorbent component.

[0028] Furthermore, the rotary joint is equipped with a rotating plate located inside the annular cavity. The rotating plate divides the annular cavity into a main cavity and a secondary cavity. The main cavity is connected to the hollow cavity through an exhaust port, and the secondary cavity is equipped with an adjustment hole.

[0029] Furthermore, the cutting device includes a sliding table, which is installed inside the cutting table. A lifting mechanism is mounted on the sliding table, and an electric cutting machine is mounted on the lifting mechanism.

[0030] The cutting table has a cutting slit. The sliding table can drive the lifting mechanism and the electric cutting machine to move along the cutting slit. The lifting mechanism can drive the electric cutting machine up and down, so that the electric cutting machine's blade extends out of the cutting slit; the control system automatically adjusts the height of the blade extending out of the cutting slit according to the thickness of the aluminum plate, completing the intelligent positioning of the blade. The electric cutting machine is equipped with a liquid spraying mechanism, which sprays coolant onto the cutting area during cutting.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. The amount of pressure on the bladder is adjusted by the telescopic rod, so that the inflation degree of the expansion tube can adapt to the size of the cutting gap. This drives the water-absorbing sleeve to adjust to the diameter that matches the cutting gap, improving the fit between the expansion water-absorbing component and the inner wall of the cutting gap, and ensuring the liquid absorption, wiping and cleaning effect.

[0033] 2. By moving the expansion absorber along the cutting seam, the residual coolant in the cutting seam and the debris on the cross-section can be absorbed and removed simultaneously during the inspection. This not only improves the cleanliness of the cutting seam area, but also provides a good foundation for subsequent cross-section quality inspection.

[0034] 3. By utilizing the changes in resistance encountered by the expansion water-absorbing component as it passes through different cross-sectional areas, the electrical signal output by the piezoelectric element is converted into an electrical signal. This allows for the preliminary identification of cutting abnormalities such as burrs, local roughness, and heavy saw marks. Furthermore, by combining the corresponding relationship of the plate length, the abnormal areas can be located, thus achieving preliminary detection of cutting quality.

[0035] 4. By completing pre-inspection first, the industrial camera is only called for fixed-point imaging analysis when abnormal areas are detected. There is no need to scan the entire cutting section segment by segment. This reduces the impact of coolant reflection and debris obstruction on imaging accuracy and reduces invalid inspection time. Thus, while ensuring cutting quality, the inspection efficiency and continuous production capacity of aluminum plate cutting operations are improved.

[0036] 5. The air plate is alternately inflated and deflated by the air inflation device, which causes the rotating plate to swing back and forth continuously. This further drives the absorbent jacket to twist back and forth, thereby squeezing out the liquid adsorbed inside the absorbent jacket. The liquid can be wrung out without disassembly, restoring the absorbent jacket's liquid absorption capacity and preventing the liquid accumulation from reducing the liquid absorption effect. This ensures the stability and continuity of subsequent crack cleaning and inspection operations. Attached Figure Description

One end of the gas channel 5511 is connected to the inflation connector 553, and the other end of the gas channel 5511 is connected to the inflation plate 552.

[0059] The inflation device can extract or release gas, and is used to inject or extract gas into the inflation plate 552 through the inflation connector 553 and the gas channel 5511. The inflation plate 552 has a hollow cavity 5522, and a number of exhaust holes 5521 are provided on one side of the hollow cavity 5522. The hollow cavity 5522 is connected to the gas channel 5511.

[0060] The expansion suction component 57 includes an expansion tube 571, the top end of which is connected to the desiccant shell 551, and the bottom end of which is connected to the diameter adjustment mechanism 56. A suction sleeve 572 is fitted on the expansion tube 571. A rotary joint 574 is connected to the top end of the suction sleeve 572. The rotary joint 574 is rotatably installed inside the desiccant shell 551. A fixed joint 573 is connected to the bottom end of the suction sleeve 572. The fixed joint 573 is installed inside the diameter adjustment mechanism 56.

[0061] The expansion tube 571 is made of a flexible, expandable material; the absorbent sleeve 572 is made of a flexible, absorbent material. The expansion tube 571 can be a rubber tube, and the absorbent sleeve 572 can be an absorbent cotton sleeve. The absorbent sleeve 572 expands along with the expansion tube 571 and absorbs the coolant.

[0062] The rotary joint 574 is provided with a rotating plate 5741, which is located in the annular cavity 5512. The rotating plate 5741 divides the annular cavity 5512 into a main cavity 5514 and a secondary cavity 5513. The main cavity 5514 is connected to the hollow cavity 5522 through the exhaust hole 5521, and the secondary cavity 5513 is provided with an adjustment hole 5515.

[0063] The working principle of this invention is as follows: During operation, the aluminum plate is first placed in the positioning frame 4, and the control system activates the fixing mechanism 3 to fix the aluminum plate. Subsequently, the control system activates the cutting device 2, and the lifting mechanism 23 drives the electric cutting machine 21 to rise and fall. After the blade is positioned, the sliding table 22 drives the electric cutting machine 21 to move along the cutting seam while cutting the aluminum plate.

[0064] Before the seam cleaning and inspection operation, the control system activates the telescopic rod 562. The output shaft of the telescopic rod 562 drives the extrusion plate 563 to move, applying extrusion pressure to the bladder 564. After the bladder 564 is compressed, the gas inside is transported to the expansion tube 571 through the connecting channel 5611, causing the expansion tube 571 to expand. The control system can adjust the extension of the output shaft of the telescopic rod 562 according to the size of the seam gap to control the degree of extrusion of the bladder 564 by the extrusion plate 563, thereby controlling the amount of gas entering the expansion tube 571 and the degree of expansion of the expansion tube 571. This allows the expansion tube 571 to drive the water-absorbing sleeve 572 to expand to a size that matches the seam gap, thus achieving adaptive adjustment of the diameter of the expansion water-absorbing component 57.

[0065] After cutting, the control system activates the upper slide rail 51 and the lower slide rail 52, causing the upper detection slide 53 and the lower detection slide 54 to move synchronously and at a uniform speed along the cutting seam. The upper detection slide 53 drives the dehydration mechanism 55 to move, and the lower detection slide 54 drives the diameter adjustment mechanism 56 to move. The dehydration mechanism 55 and the diameter adjustment mechanism 56 work together to move the expansion and suction component 57 along the cutting seam. During the movement, the expansion and suction component 57 uses its external suction sleeve 572 to absorb the residual coolant in the cutting seam and pushes away the debris adhering to the cut surface, thus completing the dehydration and seam cleaning process of the cutting seam.

[0066] When the cut surface is relatively flat and smooth, the contact resistance encountered by the expansion and water absorption component 57 during its movement along the cut is small and the resistance is relatively stable. The liquid removal mechanism 55 and the diameter adjustment mechanism 56 can drive the expansion and water absorption component 57 to maintain stable movement.

[0067] When the cut surface has burrs, excessive roughness, heavy saw marks, or other cutting abnormalities, the contact resistance between the expansion absorber 57 and the cut surface will increase significantly when passing through the corresponding area, resulting in local obstruction. This obstruction will cause the expansion absorber 57 to exhibit a relatively lag in movement, pulling on the dehydration mechanism 55 and the diameter adjustment mechanism 56, and further causing relative displacement between the connecting slide head 531 and the uniformly moving drive slider 532. During this relative displacement, the connecting slide head 531 pushes the paddle 533 to compress the elastic element 534. After compression, the elastic element 534 applies pressure to the piezoelectric element 536 via the pad 535. The piezoelectric element 536 outputs an electrical signal corresponding to the magnitude of the pressure applied. The more severe the cut surface problem, the greater the resistance experienced by the expansion absorber 57 in the corresponding area, the more pronounced the relative displacement between the connecting slide head 531 and the drive slider 532, and the higher the intensity of the electrical signal output by the piezoelectric element 536.

[0068] The control system makes a preliminary judgment on the quality of the cut surface based on the strength of the electrical signal output by the piezoelectric element 536: when the electrical signal is within the set standard range, the cutting quality of that area is judged to be normal; when the electrical signal is higher than the standard value, the corresponding area is judged to have a cutting abnormality. At the same time, the continuous electrical signal generated by the expansion water-absorbing element 57 as it moves along the entire cutting seam can form a corresponding detection signal curve. The control system then matches this signal curve with the length of the board material to locate the problematic area of ​​the board material corresponding to the abnormal fluctuation.

[0069] When the inspection results indicate the presence of abnormal areas, the control system activates the external material transfer device to move the cut sheet metal to the industrial camera inspection station. The system then controls the industrial camera to perform targeted imaging inspection of the identified non-conforming areas to further identify the specific defect types and analyze their causes. Since the expansion absorbent component 57 has already simultaneously removed residual liquid and cleaned debris from the cut surface during the pre-inspection process, interference from factors such as coolant reflection and debris obstruction on the imaging field of view can be avoided, thereby reducing the probability of misjudgment and improving imaging inspection accuracy.

[0070] If no abnormalities are found in the pre-inspection results, there is no need to call the industrial camera to scan and inspect the entire cut section segment by segment, and continuous cutting operations can be carried out directly. Thus, the purpose of cleaning the cutting seam and pre-inspecting the section is achieved simultaneously through the expansion water absorption component 57; by pre-positioning the abnormal area, the invalid scanning range of the industrial camera can be reduced, the overall inspection time can be shortened, and the continuity of aluminum plate cutting production and inspection efficiency can be improved while ensuring the accuracy of cutting quality judgment.

[0071] After the crack cleaning and inspection operation is completed, the control system starts the inflation device. The inflation device alternately inflates and deflates the inflation plate 552 through the inflation connector 553 and the gas channel 5511. During inflation, the gas first enters the hollow cavity 5522, and then enters the main cavity 5514 through the exhaust hole 5521 on one side of the hollow cavity 5522, which increases the air pressure in the main cavity 5514 and pushes the rotating plate 5741 to deflect towards the secondary cavity 5513. During this process, the volume of the main cavity 5514 increases, the volume of the secondary cavity 5513 decreases, and the air in the secondary cavity 5513 is discharged through the adjustment hole 5515. During the evacuation, the inflation device draws the gas out of the main chamber 5514 through the inflation plate 552, causing the main chamber 5514 to contract and the air pressure to decrease. The secondary chamber 5513 expands accordingly, and external air enters the secondary chamber 5513 through the adjustment hole 5515. Under the action of pressure difference, the rotating plate 5741 deflects in the opposite direction to the main chamber 5514 and resets.

[0072] By alternating inflation and deflation, the rotating plate 5741 continuously oscillates back and forth, causing the rotary joint 574 to reciprocate within the annular cavity 5512. The rotary joint 574 further drives the top of the absorbent sleeve 572 to reciprocate. Since the bottom of the absorbent sleeve 572 is fixed, when the top reciprocates, the absorbent sleeve 572 as a whole undergoes reciprocating torsion, thereby squeezing out the liquid adsorbed within the absorbent sleeve 572. This achieves the wringing out process of the absorbent sleeve 572, allowing it to regain its liquid absorption capacity without disassembly, thus meeting the operational requirements of continuous crack cleaning and inspection.

[0073] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
