Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting machines, and in particular relates to a novel coiled material laser cutting machine. Background Art

[0002] In the traditional laser coil cutting industry, manual sorting is generally used. However, due to the wide variety of parts in an order and their similar shapes, manual sorting alone is prone to errors. Therefore, adding labels to parts has become an industry trend to achieve product tracking. Currently, the main methods for adding labels are manual labeling and inkjet printers. Obviously, the existing methods still have shortcomings. Manual labeling is inefficient and prone to errors, while inkjet printers are inefficient and the inkjet printer is easily contaminated, resulting in poor coding results. Therefore, it is necessary to propose a new coil laser cutting machine to solve the above problems. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a new type of coil laser cutting machine, which combines a galvanometer marking device with a laser cutting module, flattens the coil and marks it on the fly during the transportation of the coil, and completes the marking when the coil reaches the laser cutting module, realizing the combination of dynamic marking and static cutting, and effectively improving production efficiency.

[0004] In order to achieve the above-mentioned purpose of the utility model, the technical solution adopted by the utility model is as follows:

[0005] A novel coil laser cutting machine includes a feeding and marking module and a laser cutting module. The feeding and marking module is arranged in front of the laser cutting module. The feeding and marking module includes a feeding device and a galvanometer marking device.

[0006] The feeding device includes a first frame, a transport roller and a lower pressing wheel group. The transport roller and the lower pressing wheel group are both arranged in the first frame. The lower pressing wheel group is located directly above the transport roller. A flattening feeding area is formed between the transport roller and the lower pressing wheel group. The height of the flattening feeding area is equal to the thickness of the coil; the galvanometer marking device is arranged above the rear end of the first frame, between the first frame and the laser cutting module.

[0007] In the present invention, the originally bent and curled coiled material becomes a flat surface after being flattened by the feeding device, which is convenient for the subsequent galvanometer marking device to mark it and is also beneficial for the subsequent cutting process.

[0008] Preferably, the feeding device further comprises a guide roller group leading to the laser cutting module, the guide roller group is located behind the transport roller, and the guide roller group and the transport roller are in the same horizontal plane, and the galvanometer marking device is located directly above the guide roller group;

[0011] Preferably, a one-way cylinder is provided between the synchronous roller and the roller bracket, and the outer end of the piston rod of the one-way cylinder is connected to the synchronous roller.

[0014] Preferably, the arrangement direction of the hobbing rack is perpendicular to the movement direction of the bottom conveyor belt.

[0015] Preferably, the conveying device further comprises a material unloading auxiliary plate, which is tilted toward the rolling rack above the rear end conveying wheel to facilitate guiding the products on the rolling rack out of the conveying device and into the subsequent material unloading device.

DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0025] The technical solution of the present utility model is described in detail below with reference to specific embodiments.

[0026] like Figure 1-4 As shown, the utility model provides a new type of coil laser cutting machine, including a feeding marking module and a laser cutting module, such as Figure 1 As shown, the feeding marking module is set in front of the laser cutting module, that is, according to the perspective of the attached figure, the feeding marking module is on the right, which is the "front", and the laser cutting module is on the left, which is the "back". The feeding direction is Figure 1The viewing angle is from right to left. The feeding marking module is connected to the laser cutting module, and the marked coil 4 is fed into the laser cutting module for cutting.

[0027] The utility model further comprises a control device, the feeding marking module and the laser cutting module are both connected to the control device, and the electrical components in the feeding marking module and the laser cutting module are both controlled by the control device.

[0028] The feeding marking module of the present invention includes a feeding device and a galvanometer marking device 5, such as Figure 1 As shown, the galvanometer marking device 5 is arranged behind the feeding device, and the galvanometer marking device 5 is above the coil 4.

[0029] Since the coil 4 may bend and curl during the feeding process, the feeding device of the present invention has the function of flattening and feeding the coils 4 of different specifications. Figure 1 As shown, the feeding device includes a transport roller 2 and a lower pressure wheel group 3 arranged along the feeding direction. The transport roller 2 and the lower pressure wheel group 3 are both arranged in the first frame 1. The lower pressure wheel group 3 is located directly above the transport roller 2, and the coil 4 passes through the flattened feeding area between the lower pressure wheel group 3 and the transport roller 2. It is easy to understand that the transport roller 2 is powered and serves to convey the coil 4. The lower pressure wheel group 3 can have rotational power or can be driven rotation. When the lower pressure wheel group 3 is powered, the rotation of the lower pressure wheel group 3 must cooperate with the transport roller 2 to convey the coil 4.

[0030] The length of the transport roller 2 is greater than or equal to the length of the lower pressing wheel set 3 . Preferably, the length of the transport roller 2 is equal to the length of the lower pressing wheel set 3 . The galvanometer marking device 5 is located behind the end of the transport roller 2 .

[0031] like Figure 1 As shown, the feeding device also includes a guide roller group 7, which is located behind the transport roller 2 and connected to the laser cutting module, connecting the transport roller 2 with the laser cutting module, and the guide roller group 7 and the transport roller 2 are at the same height. The galvanometer marking device 5 is located directly above the guide roller group 7. The coil 4 entering the guide roller group 7 is in a flattened state, which facilitates the galvanometer marking device 5 to mark the coil 4. It is easy to understand that the guide roller group 7 can be driven by an external motor or can be unpowered. When the guide roller group 7 is powered, the feeding speed of the guide roller group 7 and the transport roller 2 is the same, so as to avoid the situation where the coil 4 is piled up or stretched due to the different speeds when crossing the guide roller group 7 and the transport roller 2.

[0032] In the present invention, the gap between the lower pressing wheel group 3 and the transport roller 2 is small. When the coil 4, which originally has a tendency to bend and curl, enters the feeding device, under the restrictive effect of the lower pressing wheel group 3, the coil 4 is continuously flattened during the forward process and is fed to the bottom of the galvanometer marking device 5 for flying marking.

[0033] Furthermore, a synchronous roller 8 is provided above the front end of the guide roller group 7. As shown in the figure, the synchronous roller 8 is mounted on the rear end of the first frame 1 via a roller bracket 9. There is also a gap between the guide roller group 7 and the synchronous roller 8, which is the same height as the gap between the lower pressure roller group 3 and the transport roller 2. Furthermore, a synchronous encoder is provided at the synchronous roller 8 to detect the displacement of the coil 4 and the movement speed of the coil 4. Specifically, since the gap between the front end of the guide roller group 7 and the synchronous roller 8 is small, when the coil 4 passes by, the synchronous roller 8 actually applies pressure to the coil 4. At the same time, the synchronous roller 8 also rotates due to friction. That is, the distance the coil 4 moves can be converted into the number of rotations of the synchronous roller 8 and detected by the synchronous encoder. Similarly, the speed of the coil 4 is also detected by the synchronous encoder. The control system receives the information of the synchronous encoder and controls the galvanometer marking device 5 to perform flying marking on the coil 4.

[0034] Furthermore, a one-way cylinder (not shown) is vertically mounted on the roller bracket 9. The piston rod of the one-way cylinder faces downward, and the outer end of the piston rod is connected to the synchronous roller 8. In other words, the height of the synchronous roller 8 is controlled by the one-way cylinder, and the height of the gap between the synchronous roller 8 and the guide roller assembly 7 is adjustable to ensure contact between the synchronous roller 8 and the web 4. It is easy to understand that a rubber layer can be provided on the rolling surface of the synchronous roller 8 to increase the friction between the synchronous roller 8 and the web 4. In addition, the height of the synchronous roller 8 can also be adjusted to accommodate webs 4 of varying thicknesses.

[0035] In the present invention, the lower pressing wheel group 3 can be connected to a lifting mechanism, and the lifting mechanism is connected to the first frame 1, which is not shown in the accompanying drawings, so as to achieve the adjustment of the height of the lower pressing wheel group 3. It is easy to understand that the lifting mechanism can be various, as long as it is a structure that can lift and lower vertically. For example, the lifting mechanism is a structure with a screw transmission mechanism as the main body, and the nut of the screw transmission mechanism is fixedly connected to the lower pressing wheel group 3. Under the action of the screw of the screw transmission mechanism, the lower pressing wheel group 3 is lifted and lowered. The lifting mechanism can also be a plurality of groups of vertically arranged cylinder mechanisms, and the piston rod ends of the cylinder mechanisms are all connected to the lower pressing wheel group 3, thereby achieving the lifting and lowering of the lower pressing wheel group 3.

[0036] Furthermore, at least one detection sensor is provided within the conveyor roller 2, located near the front end of the conveyor roller 2 (not shown in the accompanying drawings). When the coil 4 enters the conveyor roller 2 and is detected by the detection sensor, the lower pressing wheel assembly 3 automatically presses downward. The detection sensor is a conventional infrared sensor.

[0037] Furthermore, a pressure sensor is provided at the connection between the lower pressing wheel assembly 3 and the lifting mechanism to detect the pressure applied by the lower pressing wheel assembly 3 to the coil 4, so that the lower pressing wheel assembly 3 can maintain a stable pressure on the coil 4. In addition, the lifting mechanism and the pressure sensor can also make the lower pressing wheel assembly 3 suitable for coils 4 of different specifications and thicknesses.

[0038] It is easy to understand that the lifting direction and amplitude of the lower pressure wheel group 3 and the synchronous roller 8 are the same, ensuring that the gap between the lower pressure wheel group 3 and the transport roller 2 and the gap between the synchronous roller 8 and the guide roller group 7 are kept consistent in height.

[0039] As shown in the figure, the galvanometer optical path of the galvanometer marking device 5 is connected to the first frame 1 through the mounting bracket 6. The galvanometer marking head of the galvanometer marking device 5 faces the guide roller group 7 below, and the synchronous roller 8 is located between the galvanometer marking head and the first frame 1. The galvanometer marking device 5 performs flying marking on the coil 4 according to the movement distance and speed of the coil 4 and the position where the coil 4 is subsequently cut.

[0040] The laser cutting module of the present invention includes a cutting device 10 and a conveying device 12, wherein the cutting module is arranged above the second frame 11, and includes a fiber optic cutting head and a three-axis motion mechanism. It is easy to understand that the three-axis motion mechanism is an existing conventional motion mechanism controlled by three sets of screw mechanisms, which drives the fiber optic cutting head to move along the X-axis, Y-axis and Z-axis directions to realize the movement of the fiber optic cutting head in space.

[0041] The conveying device 12 is arranged in the second frame 11 and is located below the cutting device 10. The structure of the conveying device 12 can be diverse, as long as it can realize feeding, such as a conveyor belt mechanism or a roller mechanism or other suitable mechanism. Space needs to be left for the position of the conveying device 12 relative to the cutting device 10 to avoid affecting laser cutting.

[0042] The transmission device 12 of the present invention includes a transmission motor, a transmission wheel 13 and a hobbing transmission belt. Figure 1 As shown, the transmission wheels 13 at both ends are respectively arranged in the second frame 11 and driven to rotate by the transmission motor. The gear conveyor belt is set outside the two transmission wheels 13 and driven to reciprocate by the transmission wheels 13. Specifically, the structure of the gear conveyor belt is as shown in FIG. Figure 2 and 3As shown, it includes a bottom conveyor belt 18 and multiple sets of rolling racks 19 arranged parallel to the bottom conveyor belt 18. Multiple sets of identical rolling racks 19 are densely distributed on the bottom conveyor belt 18. The bottom conveyor belt 18 is sleeved outside the two conveying wheels 13. The setting direction of the rolling racks 19 is perpendicular to the direction of their advancement. The multiple sets of rolling racks 19 support and convey the coil 4. Because there are gaps between adjacent rolling racks 19 and the same rolling rack 19 contacts the coil 4 in point form, the cutting device 10 has little effect on the rolling racks 19 during the cutting process.

[0043] Furthermore, the rack gear 19 is detachably mounted on the bottom conveyor belt 18. When the rack gear 19 needs to be replaced, only the damaged rack gear 19 can be replaced without replacing the entire rack gear conveyor belt.

[0044] Furthermore, the conveying device 12 further includes a blanking auxiliary plate 20, such as Figure 2 and 4 As shown, the unloading auxiliary plate 20 is tilted toward the hob rack 19 above the rear conveyor wheel 13, and the front edge of the unloading auxiliary plate 20 is the inverse tooth of the hob rack 19. That is, the serrations at the front end of the unloading auxiliary plate 20 face the gaps between adjacent serrations in the hob rack 19. When the toothed conveyor belt rotates to feed, the cut products are transported close to the unloading auxiliary plate 20. As they move to the rear conveyor wheel 13, the hob rack 19 closest to the unloading auxiliary plate 20 descends due to the curved surface of the conveyor wheel 13. The products originally at this position are supported by the serrated front end of the unloading auxiliary plate 20. As unloading continues, the products enter the unloading auxiliary plate 20 and leave the toothed conveyor belt.

[0045] In the present invention, the control device includes at least a cutting system controller 16, a cutting-marking system controller 17, a marking system controller 15, and a flattening feed controller 14. The marking system controller 15 and the flattening feed controller 14 are located within the first frame 1. The marking system controller 15 controls the galvanometer marking device 5. The flattening feed controller 14 controls the feeding device, more specifically, the speed of the transport roller 2 and the lifting height of the lower pressing wheel group 3. The cutting system controller 16 and the cutting-marking system controller 17 are located within the second frame 11. The cutting system controller 16 controls the cutting device 10 to cut the coil 4. The data information of the synchronous encoder is received by the cutting-marking system controller 17. When the marking system controller 15 receives the marking information from the cutting-marking system controller 17, the galvanometer marking device 5 marks the coil 4.

[0046] The working process of this utility model is:

[0047] The coil 4 enters the transport roller 2, and the lower pressure wheel group 3 applies pressure to the coil 4. Under the rotation of the transport roller 2, the coil 4 moves forward. During the movement, the coil 4 is flattened to prepare for subsequent marking and cutting. When the coil 4 moves between the synchronous roller 8 and the guide roller group 7, the moving distance and speed of the coil 4 are detected by the synchronous encoder. The galvanometer marking device 5 performs flying marking according to the detection results. The marked coil 4 enters the cutting device 10 for cutting processing, which effectively improves production efficiency.

[0048] The embodiments provided by the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the core concept of the present invention. It should be noted that, for those skilled in the art, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
