Description

Technical Field

[0001] This utility model belongs to the field of laser cutting equipment technology, and specifically relates to a profile laser cutting machine. Background Technology

[0002] Currently, laser cutting equipment mainly focuses on round, square, and rectangular tubes, with processes including loading, cutting, and unloading. However, while the cutting process can be automated, the loading and unloading processes still require manual assistance. There is a lack of automated equipment to achieve automatic alignment and loading / unloading, especially in the loading process. After the profile is loaded, manual alignment is required before feeding and cutting. During the feeding and cutting process, it is also necessary to continuously maintain the profile's stability, resulting in low work efficiency. Furthermore, excessive human intervention can easily lead to inaccuracies. Therefore, it is necessary to propose a new type of profile laser cutting machine. Utility Model Content

[0003] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a profile laser cutting machine.

Detailed Implementation

[0032] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0033] like Figure 1-8 As shown, this utility model provides a profile laser cutting machine, which is suitable for profiles that can be clamped at both ends. It includes a feeding module 1, a cutting module 2 and a unloading module 3. The cutting module 2 is located between the feeding module 1 and the unloading module 3. The feeding module 1 realizes automatic alignment and automatic feeding of the profile, and the unloading module 3 realizes automatic unloading of the cut profile.

[0034] In this utility model, "front" and "rear" refer to the feeding and unloading directions. Specifically, for the feeding module 1, the end closer to the cutting module 2 is the front, and the end farther from the cutting module 2 is the rear; for the unloading module 3, the end closer to the cutting module 2 is the rear, and the end farther from the cutting module 2 is the front.

[0035] The feeding module 1 includes a feeding roller conveyor, a feeding device, and a clamping device. The feeding roller conveyor achieves automatic alignment. The clamping device is connected to the feeding device and clamps one end of the profile. The clamping device is controlled by the feeding device to move along the feeding direction to achieve automatic feeding.

[0036] Specifically, if Figure 1 and 2 As shown, the feeding roller conveyor device includes multiple feeding roller conveyor groups 11 and multiple alignment mechanisms 4. The feeding roller conveyor group 11 can be connected to an external power source or not. In this utility model, preferably, the rollers of the feeding roller conveyor group 11 are in free rotation, which reduces the friction of the profile movement. The movement of the profile is controlled by the feeding device.

[0037] In this utility model, multiple feeding roller conveyor groups 11 are connected and fixed end to end. Each feeding roller conveyor is provided with at least one alignment mechanism 4. The alignment mechanism 4 includes an alignment cylinder 41, a fixed guide wheel 42, and a movable guide wheel 43, such as... Figure 1-3 As shown, the alignment cylinder 41 is fixedly mounted on one side of the frame of the feeding roller conveyor group 11, and the extension direction of the piston rod of the alignment cylinder 41 is perpendicular to the direction of profile advancement. A fixed guide wheel 42 is provided at the top of the side of the frame near the alignment cylinder 41. Preferably, the fixed guide wheel 42 is located directly above the alignment cylinder 41. A movable guide wheel 43 is provided at the outer end of the piston rod of the alignment cylinder 41. The distance between the fixed guide wheel 42 and the movable guide wheel 43 is changed by the extension and retraction of the piston rod. It is easy to understand that when the profile is on multiple feeding roller conveyor groups 11, the piston rod of the alignment cylinder 41 retracts, and the movable guide wheels 43 of multiple alignment mechanisms 4 push the profile as a whole towards the fixed guide wheel 42, thereby achieving automatic alignment. The profile can move between the movable guide wheel 43 and the fixed guide wheel 42, and the feeding device can drive the profile to move freely along the feeding direction.

[0038] In this invention, the movable guide wheel 43 and the fixed guide wheel 42 are higher than the rollers in the feeding roller conveyor group 11.

[0039] Furthermore, the frame of the feeding roller conveyor group 11 is equipped with an auxiliary guide rail 44 that cooperates with the moving guide wheel 43, such as... Figure 3 As shown, the auxiliary guide rail 44 is parallel to the extension and retraction direction of the piston rod of the alignment cylinder 41. One side of the movable guide wheel 43 is slidably connected to the auxiliary guide rail 44, that is, the piston rod drives the movable guide wheel 43 to move along the auxiliary guide rail 44, approaching or moving away from the corresponding fixed guide wheel 42.

[0040] like Figure 2 and 4 As shown, the feeding device includes a side guide rail 13 and a drive mechanism. The side guide rail 13 is located on the outside of the feeding roller conveyor group 11. The length of the side guide rail 13 should be greater than the total length of the feeding roller conveyor group 11. For ease of control, the side guide rail 13 is flush with the feeding roller conveyor group 11 at the end near the cutting module 2, and the end of the side guide rail 13 away from the cutting module 2 protrudes from the feeding roller conveyor group 11 to facilitate the retraction and reset of the clamping device. The drive mechanism is located on the side guide rail 13 and moves along the side guide rail 13. The clamping device is connected to the drive mechanism. It is easy to understand that the structure of the drive mechanism can be diverse. Its main function is to drive the clamping device forward or backward. For example, the drive mechanism can be a screw mechanism. The screw and motor of the screw mechanism are located on the side guide rail 13, and the nut of the screw mechanism is located on the clamping device, thereby realizing the movement of the clamping device. For example, the drive mechanism can be a chain-driven drive mechanism, with the motor and reciprocating chain mounted on the side guide rail 13. The clamping device is equipped with a fixing block fixedly connected to the chain. The motor drives the chain to reciprocate, thereby realizing the forward or backward movement of the clamping device. For example, the drive mechanism can be a drive mechanism with gear 1204 and rack 1203.

[0041] Preferably, the driving mechanism of this utility model is a driving mechanism with gear 1204 and rack 1203. The driving mechanism includes a moving base plate 1202, a drive motor 1201, rack 1203 and gear 1204, as shown below. Figure 4 As shown, guide rails are provided on the top surface of the side guide rail 13 and the side surface from the perspective of the attached drawing. The movable base plate 1202 is inverted L-shaped. The guide rails on both sides of the base plate and the side guide rail 13 are slidably connected. The clamping device is fixedly connected to the side surface of the movable base plate 1202. A rack 1203 is also provided on the top surface of the side guide rail 13 along the length direction. The drive motor 1201 is provided on the top surface of the movable base plate 1202, and the drive shaft of the drive motor 1201 is connected to the gear 1204. The gear 1204 meshes with the rack 1203. When the drive motor 1201 drives the gear 1204 to rotate, the clamping device moves forward or backward along the side guide rail 13 under the action of the gear 1204.

[0042] Furthermore, a stop 1301 is provided at the end of the side guide rail 13, and a first proximity sensor 1205 that cooperates with the stop 1301 is provided on the edge of the movable base plate 1202, such as... Figure 4 As shown, the first proximity sensor 1205 is located at the outer end of the side guide rail 13 away from the cutting module 2 to prevent the moving mechanism 12 from retracting excessively and causing it to disengage.

[0043] like Figure 4 and 5As shown, the clamping device includes a lifting mechanism 15 and a clamping mechanism 14. The clamping mechanism is connected to the clamping mechanism 14, thereby enabling the clamping mechanism 14 to be raised and lowered to adapt to profiles of different specifications. The lifting mechanism 15 is connected to the drive mechanism, and automatic feeding is achieved through the drive mechanism.

[0044] The lifting mechanism 15 of this utility model can also take various forms, as long as it has an adjustable lifting function. For example, the lifting mechanism 15 can be a cylinder-driven mechanism, a lead screw mechanism, a gear 1204 rack 1203 mechanism driven by a motor, a transmission chain mechanism driven by a motor, or other structures that meet the requirements.

[0045] Specifically, the lifting mechanism 15 of this utility model is preferably a lead screw mechanism, which facilitates precise adjustment. As shown in the figure, the lifting mechanism 15 includes a lifting motor 1502, a lead screw transmission mechanism 1504, and a lifting base plate 1501. The lifting base plate 1501 is vertically fixed on one side of the movable base plate 1202. Two sets of parallel linear guide rail pairs 1503 are vertically arranged on the movable base plate 1202. The clamping mechanism 14 is connected to the linear guide rail pairs 1503. The screw of the lead screw transmission mechanism 1504 and the lifting motor 1502 are arranged on the lifting base plate 1501. The nut of the lead screw transmission mechanism 1504 is fixedly connected to the clamping mechanism 14, thereby realizing that the lifting motor 1502 drives the clamping mechanism 14 to lift.

[0046] The clamping mechanism 14 of this utility model mainly functions to clamp the profile. Its structure can be varied. Preferably, the clamping mechanism 14 includes a fixed base plate 1401, an adjusting base plate 1402, a clamping cylinder 1404, a clamping base 1405, and a clamping arm 1407. Figure 4-6 As shown, the fixed base plate 1401 is connected to the lifting mechanism 15. Specifically, the fixed base plate 1401 is connected to the lead screw transmission mechanism 1504 and the linear guide pair 1503 of the lifting mechanism 15. The lifting mechanism 15 controls the lifting of the fixed base plate 1401, as shown in the attached figure. Figure 6 As shown in the view, the adjusting base plate 1402 is disposed on the side of the fixed base plate 1401 away from the lifting mechanism 15, and the clamping cylinder 1404, clamping base 1405, and clamping arm 1407 are disposed on the side of the adjusting base plate 1402 away from the fixed base plate 1401. Specifically, as shown in the view... Figure 4 and 5As shown, the tail end of the clamping cylinder 1404 is hinged to the connecting seat 1403 of the adjusting base plate 1402. The clamping base 1405 is located in front of the clamping cylinder 1404. The clamping cylinder 1404 is located between the clamping base 1405 and the connecting seat 1403 and is in an inclined state. The clamping arm 1407 is disposed inside the clamping base 1405 and can rotate around its connection. The top end of the clamping arm 1407 is hinged to the piston rod of the clamping cylinder 1404. The bottom end of the clamping arm 1407 is above the fixed arm 1406 extending outward from the clamping base 1405. The piston rod of the clamping cylinder 1404 extends outward and pushes the bottom end of the clamping arm 1407 to press against the fixed arm 1406. The piston rod of the clamping cylinder 1404 retracts and pulls the bottom end of the clamping arm 1407 away from the fixed arm 1406.

[0047] It is easy to understand that the area between the bottom end of the clamping arm 1407 and the fixed arm 1406 is the position for clamping the profile, and the clamping cylinder 1404 controls the clamping or releasing of the profile. The clamping cylinder 1404, clamping arm 1407, connecting seat 1403, and clamping base 1405 form a linkage-like structure, allowing the bottom end of the clamping arm 1407 to apply pressure perpendicular to the profile more effectively, thus clamping the profile more firmly. Figure 5 As shown, the clamping arm 1407 is a sideways Z-shape. The middle of the clamping arm 1407 is rotatably connected to the clamping seat via a pin. When clamping the profile, the bottom end of the clamping arm 1407 has a large contact area with the profile, which helps prevent the profile from falling off when the clamping mechanism 14 pulls the profile. Furthermore, an anti-slip pad is provided at the fixed arm 1406 to ensure a firm grip on the profile.

[0048] Furthermore, the length of the adjusting base plate 1402 is adjustable (not shown in the attached figure), which facilitates adjusting the extension distance of the clamping mechanism 14. It is easy to understand that when the extension distance of the clamping mechanism 14 is longer, the distance between the clamping mechanism 14 and the moving mechanism 12 is larger. That is, even after the moving mechanism 12 moves to its limit position near the cutting module 2, the clamping mechanism 14 can still feed the profile tail into the cutting module 2 for cutting. Optionally, the adjusting base plate 1402 can be composed of multiple sub-plates connected together. Taking two sub-plates as an example, the two sub-plates are fixedly connected by bolts and nuts. Multiple bolt and nut fixing positions are provided on the sub-plates. The overall length of the adjusting base plate 1402 is adjusted by adjusting the overlap length of the two sub-plates. The front sub-plate is equipped with components such as a clamping cylinder 1404, a clamping base 1405, and a clamping arm 1407. The rear sub-plate is connected to the fixed base plate 1401, thereby adjusting the distance between the clamping station and the moving mechanism 12.

[0049] like Figure 4-6As shown, the fixed base plate 1401 is also provided with a first detection sensor 1408. The first detection sensor 1408 is connected to the fixed base plate 1401 through a telescopic connecting rod 1409. The first detection sensor 1408 is located above the clamping arm 1407 and outside the clamping arm 1407. It is used to detect whether there is a profile between the clamping arm 1407 and the fixed arm 1406. Specifically, the working process of the first detection sensor 1408 is as follows: there is a distance between the detection position of the first detection sensor 1408 and the clamping position of the clamping mechanism 14. When the clamping mechanism 14 moves at a constant speed towards the profile, the preset time required for the profile to move from the detection position to the clamping position can be calculated by the speed. Taking the first detection of the profile by the first detection sensor 1408 as the starting point of timing, after the preset time has elapsed, it is determined that the profile has moved to the clamping position, the clamping cylinder is activated, and the clamping arm 1407 and the fixed arm 1406 clamp and fix the profile. It is easy to understand that the extension distance of the first detection sensor 1408 can be adjusted by the connecting rod 1409 to ensure that the first detection sensor 1408 is always located outside the clamping arm 1407.

[0050] Furthermore, a second proximity sensor 1505 and a baffle 1412 are also provided between the lifting mechanism 15 and the clamping mechanism 14, such as... Figure 6 As shown, a second proximity sensor 1505 is provided on the side edge of the lifting base plate 1501, and a baffle 1412 that cooperates with the second proximity sensor 1505 is provided on the side edge of the fixed base plate 1401 to limit excessive rising or falling of the clamping mechanism 14. In this invention, the first proximity sensor 1205 and the second proximity sensor 1505 are conventional proximity switches.

[0051] Furthermore, a buffer mechanism is also provided between the adjusting substrate 1402 and the fixed substrate 1401. The buffer mechanism includes a buffer guide rod 1410 and a connecting block 1411. Specifically, as shown in the figure... Figure 6 As shown, at least two sets of parallel buffer guide rods 1410 are vertically arranged on the side of the fixed base plate 1401 facing the adjusting base plate 1402. The buffer guide rods 1410 are connected to the fixed base plate 1401 through support seats. At least two sets of connecting blocks 1411 are arranged on the side of the adjusting base plate 1402 facing the fixed base plate 1401. All connecting blocks 1411 are at the same horizontal height. The connecting blocks 1411 are sleeved on the buffer guide rods 1410 and can slide along the buffer guide rods 1410. Under normal conditions, due to gravity, the connecting blocks 1411 of the adjusting base plate 1402 are at the lowest end of the buffer guide rods 1410 and are supported by the support seats located at the lower position. When the clamping mechanism 14 or the profile is impacted and shakes, the connecting blocks 1411 can slide along the buffer guide rods 1410, providing buffer space for the clamping mechanism 14 and preventing damage to the clamping mechanism 14.

[0052] In summary, the working process of the feeding module 1 of this utility model is as follows: the external feeding device places the profile on the feeding roller conveyor device, and multiple alignment mechanisms 4 pull the profile towards the side guide rail 13 until the entire profile is on the side of the feeding roller conveyor device close to the side guide rail 13. Then, the moving mechanism 12 drives the clamping mechanism 14 to approach the end of the profile until the clamping mechanism 14 clamps the profile. Then, the moving mechanism 12 continues to drive the clamping mechanism 14 and the profile to move forward and feed the profile into the cutting module 2 for cutting. When the moving mechanism 12 moves to the limit position close to the cutting module 2, the clamping mechanism 14 is in the cutting module 2, clamping the tail material of the profile and continuing to process it, effectively solving the problem of a lot of tail material left in the existing profile processing.

[0053] like Figure 7 As shown, the cutting mechanism of this utility model includes a cutting frame 22 and a cutting processing center 23 disposed within the cutting frame 22. The cutting processing center 23 is a conventional laser cutting equipment. The end of the feeding roller device and the side guide rail 13 of the feeding module 1 are located within the cutting frame 22, and the beginning of the unloading module 3 is also located within the cutting frame 22. Furthermore, a receiving cart 5 is also disposed within the cutting frame 22. The receiving cart 5 is located between the feeding module 1 and the unloading module 3. For cutting and producing smaller-sized products, the material can be unloaded through the receiving cart 5 without going through the unloading module 3. In addition, the processing of profile tail material can also be achieved through the receiving cart 5.

[0054] The feeding module 3 includes a powered feeding roller conveyor assembly, such as... Figure 8 As shown, the rollers of the feeding roller conveyor group are connected by a drive chain and driven to rotate by the feeding motor 31, which serves the function of feeding.

[0055] The side of the unloading roller conveyor group located within the cutting module 2 is also equipped with multiple alignment mechanisms 4, which are similar to the installation method of the loading roller conveyor group 11. When cutting, the alignment mechanism 4 of the loading roller conveyor group 11 and the alignment mechanism 4 of the unloading roller conveyor group play a role in restricting the left and right movement of the profile, while the feeding mechanism plays a role in restricting the front and back movement of the profile. This determines the position of the profile, making it easier for the laser cutting equipment to process the profile.

[0056] When the material is being cut, the profile is adjusted by the alignment mechanism 4 of the material cutting module 3 and then fed out from the side of the material cutting roller conveyor group.

[0057] Furthermore, guide baffles 32 are also provided on both sides of the feeding roller conveyor group. The guide baffles 32 on the same side are distributed along the length of the feeding roller conveyor group to prevent the profile from hitting the edge of the roller. Figure 8 As shown, the guide baffle 32, which is on the same side as the alignment mechanism 4, is located behind the alignment mechanism 4 of the unloading roller conveyor group, so as to avoid obstructing the alignment mechanism 4.

[0058] Furthermore, a second detection sensor 33 is provided at one end of the feed roller assembly within the cutting module 2, for detecting the presence of the profile and recording the quantity of the feed profile.

[0059] The first detection sensor 1408 and the second detection sensor 33 of this invention are conventional sensors, such as infrared sensors, used to detect whether an object is approaching.

[0060] A central control console 21 is also installed at the cutting module 2. The feeding module 1, the unloading module 3, and the cutting module 2 are all controlled by the central control console 21. The central control console 21 is an existing conventional control system.

[0061] The working process of this utility model is as follows:

[0062] During the feeding process, the alignment mechanism 4 of the feeding roller conveyor group 11 brings the profile close to one side of the feeding roller conveyor group 11, and then the clamping mechanism 14 clamps the end of the profile. The moving mechanism 12 drives the clamping mechanism 14 to send the profile into the cutting module 2 for cutting.

[0063] For longer products, the profile spans the feeding roller conveyor group 11 and the unloading roller conveyor group. The alignment mechanism 4 of the feeding roller conveyor group 11 and the alignment mechanism 4 of the unloading roller conveyor group restrict the profile from shifting left and right. The clamping mechanism 14 stops moving and restricts the profile from moving back and forth. This stabilizes the position of the profile to be processed directly below the cutting processing center 23. After the cutting is completed, the product on the unloading roller conveyor group is directly unloaded. The clamping mechanism 14 continues to feed the material. The above operation is repeated until the remaining tail material is received. The clamping mechanism 14 continues to send the tail material to the area below the cutting processing center 23 for processing. The tail material does not contact the unloading roller conveyor group and is collected by the receiving cart 5.

[0064] For shorter products, if the profile fails to enter the unloading roller conveyor group, the alignment mechanism 4 of the loading roller conveyor group 11 restricts the profile from shifting left or right, and the clamping mechanism 14 stops moving, restricting the profile from moving back and forth. This stabilizes the position of the profile to be processed directly below the cutting processing center 23. After the cutting is completed, the profile is unloaded into the receiving cart 5.
