Description

Technical Field

[0001] The invention belongs to the technical field of door leaf processing and production, and in particular relates to an automatic unwinding, embossing and laser cutting automatic line. Background Art

[0002] Taking the processing and forming of door leaves as an example, the steel coil is uncoiled by the uncoiler and then embossed by the embossing machine. It is then sheared by the shearing machine according to the size of the door leaf. The sheared door panel is then sent to the laser cutting equipment for punching and cutting, and finally output through the discharge belt.

[0003] In this process, each working procedure requires the transfer of plates. If manual transfer is adopted, the labor intensity will inevitably increase and the production efficiency will be limited.

[0004] However, the existing automatic production lines for door leaves cannot adapt to the processing and transportation of plates of different sizes. There is a lack of guiding and transportation mechanisms suitable for plates of different sizes between each process, resulting in a separate production line for each size of door leaf, which makes the production cost too high.

[0005] The patent with the announcement number CN110394662A discloses a fully automatic laser processing production line for unwinding and unloading aluminum veneer, which includes a support seat, on which are arranged, from left to right, an unwinding machine, a leveling machine, a shearing machine, a conveyor belt, an automatic material storage warehouse, a pre-marking mechanism, a laser cutting device, and a sorting and conveying device. This solution enables the fully automatic laser processing production line for unwinding and unloading aluminum veneer to realize automation from raw materials to finished parts, greatly improving production efficiency.

[0006] However, the above solution lacks a guiding and positioning mechanism between each process, and the plate needs to be repositioned before each process to ensure accurate processing. The specific problems are as follows: 1. There is a lack of guiding mechanism at the front and rear ends of the leveling machine. The aluminum plate leveled by the leveling machine directly enters the shearing machine. However, the conveying direction of the aluminum plate is prone to a certain deviation after leveling, so the aluminum plate needs to be realigned when entering the shearing machine, otherwise deviation is likely to occur during shearing; 2. The aluminum veneers cut by the shearing machine will be directly sent to the automatic storage warehouse through the conveyor belt, and the aluminum veneers coming out of the automatic storage warehouse need to be repositioned to ensure the accuracy of marking and laser cutting; 3. The conveying platform at the bottom of the laser cutting equipment lacks edge and positioning components. It is difficult for the aluminum plate to maintain a straight line when entering the conveying platform, so it needs to be repositioned after entering under the laser cutting head, otherwise it will cause cutting errors.

[0007] It can be seen that the above problems occur in the feeding, discharging and conveying components of each process. The accumulation of errors in each process will produce large deviations, affecting the quality of the final product. Summary of the invention

DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 11 , the present invention provides a technical solution: like Figure 1-Figure 2 As shown, an automatic unwinding, embossing and laser cutting automatic line includes an unwinding machine 1, an embossing machine 3, a shearing machine 4, a conveying frame 5, a laser cutting machine 6 and a discharging belt 7 in sequence along the production direction; An unwinding transition detection station 2 is provided between the unwinding machine 1 and the embossing machine 3, and the unwinding transition detection station 2 is used to detect and adjust the unwinding speed; The embossing machine 3 is provided with a guide mechanism 31 at both the inlet and outlet ends, and the guide mechanism 31 can be adjusted in width and height; The feeding end of the plate shearing machine 4 is provided with a traction mechanism 41, and the traction mechanism 41 is used to drive the plate at the discharging end of the embossing machine 3 into the plate shearing machine 4; The conveying frame 5 includes a positioning assembly 51 and a flap assembly 52. ​​The positioning assembly 51 is fixed on the conveying frame 5 along the conveying direction, and the flap assembly 52 is located at one side of the discharge end of the conveying frame 5. The laser cutting machine 6 includes a conveying platform 61 and a laser cutting assembly 62 . The conveying platform 61 includes an inclined roller 63 , a side guard assembly 64 and a limit assembly 65 .

[0026] Through the above technical solution, the steel coil is uncoiled by the uncoiler 1, and then the uncoiled steel coil enters the embossing machine 3 through the uncoil transition detection station 2; Since the inlet and outlet ends of the embossing machine 3 are both provided with guide mechanisms 31, the guide mechanisms 31 can adjust the left and right distances according to the width of the steel coil to adapt to the steel coil, so as to keep the steel coil entering in a straight line. At the same time, a mold is provided in the embossing machine 3 for pressing out different patterns. Since the heights of different molds are different, the height of the entering steel coil can be adjusted through the guide mechanism 31 so that the steel coil and the mold are kept at the same height, which is convenient for subsequent feeding and discharging. The steel coil after embossing can be ensured to enter the shearing machine 4 in a straight line through the guide mechanism 31 at the outlet end, and there is no need to re-position the shearing machine 4, which is convenient for shearing by the shearing machine 4 and ensures shearing accuracy. At the same time, the traction mechanism 41 provided at the feeding end of the shearing machine 4 facilitates the pulling of the steel coil at the discharging end of the embossing machine 3 into the shearing machine 4 to avoid the lack of power of the steel coil at the discharging end. At the same time, the support platform 42 under the shearing machine 4 can also support the steel coil to prevent the steel coil from falling; The shearing machine 4 shears the embossed steel coil according to the required door leaf length, and finally forms steel plates. The steel plates from the shearing machine 4 enter the conveying rack 5 for positioning and temporary storage. The flap assembly 52 of the conveying rack 5 is used to limit the entry and exit of the steel plates. At the same time, the positioning assembly 51 is used to push the steel plates to one side of the conveying rack 5, so that the steel plates are output along a straight line. The steel plate passes through the conveying frame 5 and enters the laser cutting machine 6. The roller 63 arranged obliquely on the conveying platform 61 allows the steel plate to move along one side of the conveying platform 61. At the same time, the limit assembly 65 limits the discharge of the steel plate. At the same time, the side guard assembly 64 abuts the steel plate against the side plate of the conveying platform 61 on the opposite side to complete the limit and clamping, which facilitates the laser cutting assembly 62 to perform cutting, ensures the cutting position, and provides cutting accuracy. Finally, the steel plate that has been cut by laser is output through the discharging belt 7.

[0027] Through the combination of the above structures, the whole process of uncoiling, embossing, shearing and laser cutting is automated, which greatly improves the work efficiency. At the same time, there are guiding and limiting components between each process and the next process to ensure the accurate position of the steel coil from the previous process to the next process, which is convenient for the processing of subsequent processes and ensures the processing accuracy.

[0028] Continue as Figure 3-Figure 4 As shown, the unwinding transition detection station 2 is a gate-shaped structure. The steel coil passes through the unwinding transition detection station 2 from the unwinding machine 1 and enters the embossing machine 3. A distance sensor is provided on the inner side of the top of the unwinding transition detection station 2.

[0029] Through the above technical scheme, since the uncoiling speed of the uncoiler 1 and the embossing speed of the embossing machine 3 are different, when the steel coil at the uncoiling transition detection station 2 is too close to the position sensor 21, it means that the uncoiling speed is less than the embossing speed. At this time, the uncoiling speed can be accelerated or the embossing speed can be slowed down to ensure that the steel coil is not tightened between the embossing machine 3 and the uncoiler 1; on the contrary, when the steel coil at the uncoiling transition detection station 2 is too far from the position sensor 21, the uncoiling speed can be slowed down or the embossing speed can be accelerated to avoid the steel coil from piling up between the embossing machine 3 and the uncoiler 1.

[0030] Furthermore, if Figure 3-Figure 4 As shown, the guide mechanism 31 includes a roller frame 32, a lifting assembly 33 and a width adjustment assembly 34. The lifting assembly 33 is located at the bottom of the roller frame 32. The lifting assembly 33 is connected to the embossing machine 3 and the roller frame 32 respectively. The lifting assembly 33 includes a lifting screw assembly and a linear rail slider assembly; the width adjustment assembly 34 is located on the roller frame 32. The width adjustment assembly 34 includes two sets of screw adjustment plates and a roller 35 located above the screw adjustment plates.

[0031] Through the above technical solution, the lifting assembly 33 can drive the roller frame 32 and the width adjustment assembly 34 fixed on the roller frame 32 to move as a whole in the vertical direction through the lifting screw assembly and the linear rail slider assembly. At this time, the roller height of the roller frame 32 can be adjusted through the lifting assembly 33, which is convenient for the steel coil to adapt to the mold height of the embossing machine 3 and avoid collision between the steel coil and the mold.

[0032] The width adjustment assembly 34 includes two sets of symmetrically arranged mounting plates 36 and two screw rods 37 located in the middle. The two screw rods 37 pass through the mounting plates 36 on the corresponding side and the side plates on the roller frame 32, and the mounting plates 36 cooperate with the screw rods 37, so rotating the screw rods 37 can drive the mounting plates 36 to move, thereby adjusting the distance. At the same time, guide column and guide sleeve assemblies 38 are provided on both sides of the screw rods 37 for supporting and sliding the mounting plates 36. At the same time, the rollers 35 are located above both sides of the mounting plate 36, so the distance between the two mounting plates 36 is adjusted to adjust the distance between the rollers 35 on both sides. The rollers 35 can rotate freely to facilitate the movement of the steel coil entering. The width adjustment component 34 can be used to adjust the width of the steel coil. The limit of the rollers 35 on both sides allows the steel coil to accurately enter the mold in the embossing machine 3, and the steel coil can be embossed without additional positioning. At the same time, the position adjustment of the guide mechanism 31 at the discharge end of the embossing machine 3 is consistent with the position adjustment at the feed end, ensuring that the steel coil maintains a consistent position before and after embossing, which is convenient for entering the subsequent shearing machine 4 for shearing.

[0033] Furthermore, if Figure 5-Figure 6As shown, a support platform 42 is provided at the bottom of the shearing machine 4, and the support platform 42 includes a base and a give-way belt assembly 45 located on the base. The shearing machine 4 is located in the give-way gap of the give-way belt assembly 45, and the shearing machine 4 is slidably connected to both sides of the base.

[0034] Through the above technical solution, both ends of the yield belt assembly 45 are connected to the base through the rotating shaft, the supporting rotating shaft in the middle of the yield belt assembly 45 is rotatably connected to the shearing machine 4, and the yield belt assembly 45 is arranged in a U shape at the position of the shearing machine 4, so that the belt passes under the shearing machine 4 without affecting the operation of the shearing machine 4. At the same time, since the shearing machine 4 is slidably connected to the base, when the shearing machine 4 moves, it will drive the supporting rotating shaft in the middle of the yield belt assembly 45 to move, thereby synchronously adjusting the yield space of the belt.

[0035] The belt assembly 45 is used to support and convey the front and rear sides of the shearing machine 4, which can convey and support the steel plate feeding and discharging. At the same time, multiple belts are arranged at intervals to facilitate the sheared steel plate fragments to fall from the gap. The combination of the belt assembly 45 and the shearing machine 4 can adapt to the shearing of different plate lengths, flexibly adjust the position of the shearing machine 4, and improve the shearing efficiency and shearing flexibility.

[0036] Furthermore, the traction mechanism 41 is fixed on the feeding end of the base, and the traction mechanism 41 includes a fixed roller 43 and a lower pressing roller 44 which are arranged correspondingly up and down, and the lower pressing roller 44 is adjusted up and down by a screw slider assembly 46.

[0037] Through the above technical scheme, the fixed roller 43 and the lower pressure roller 44 are connected by a synchronous belt to ensure synchronous rotation. At the same time, the lower pressure roller 44 adjusts the distance between itself and the fixed roller 43 through the screw slider assembly 46 to ensure that the lower pressure roller 44 can press the steel coil onto the fixed roller 43, maintain the friction of the fixed roller 43, and facilitate traction of the steel coil.

[0038] Furthermore, if Figure 7-Figure 8As shown, multiple groups of positioning components 51 are evenly arranged on the conveying frame 5, and the positioning components 51 include a positioning plate 53, a cross beam 55, a buffer component 54 and a telescopic cylinder 56. Two groups of buffer components 54 are located on both sides of the cross beam 55. The positioning plate 53 is fixed on the buffer component 54, and the cylinder seat of the telescopic cylinder 56 is fixed on the side plate of the conveying frame 5, and one end of the piston rod of the telescopic cylinder 56 is connected to the cross beam 55; the buffer component 54 includes a bottom plate 57, a fixed block 59, a sliding block 511, a spring column 510 and a top plate 58. The bottom plate 57 is fixed on the cross beam 55, the fixed block 59 is fixed to the bottom plate 57, the sliding block 511 is fixed to the top plate 58, and the two ends of the spring column 510 are respectively connected to the fixed block 59 and the sliding block 511.

[0039] Through the above technical scheme, the positioning plate 53 is located above the roller of the conveyor frame 5, and the crossbeam 55 and the buffer assembly 54 are located below the roller of the conveyor frame 5 to avoid affecting the rotation of the roller. After the telescopic cylinder 56 drives the positioning plate 53 to abut against one side of the steel plate, as the telescopic cylinder 56 continues to move, the other side of the steel plate is pressed against the side wall of the conveyor frame 5, so that the conveying direction of the steel plate moves in a straight line along one side. At the same time, due to the presence of the buffer assembly 54, when the positioning plate 53 abuts against the steel plate, it will drive the spring column 510 to shrink to a certain extent, avoiding the hard contact between the positioning plate 53 and the steel plate, reducing the pressure on the steel plate when the positioning plate 53 drives the steel plate to the edge, so that when one side of the steel plate approaches the side wall of the conveyor frame 5, the positioning plate 53 will not cause the steel plate to deform, thereby ensuring product quality.

[0040] Furthermore, a sensor is provided on one side of the conveying frame 5 corresponding to the positioning plate 53. When one side of the steel plate abuts against the side wall of the conveying frame 5, the operation of the telescopic cylinder 56 is stopped to prevent the telescopic cylinder 56 from continuing to move and compress the plate.

[0041] Furthermore, the flap assembly 52 uses a flip cylinder and a flap. The flip cylinder drives the flap to flip over the roller of the conveyor frame 5 to limit the discharge of the steel plate. At the same time, a sensor is also provided on the side of the flap assembly 5 close to the incoming material. When the steel plate passes the sensor, the flap cylinder drives the flap to limit the discharge of the plate, and then the positioning assembly 51 acts to make the steel plate move to the edge. After the action is completed, the flip direction makes the steel plate discharge into the laser cutting machine 6.

[0042] Furthermore, if Figure 9-11 As shown, both sides of the roller 63 are rotatably connected to the side plates of the conveying platform 61 , and a plurality of discs 66 are evenly arranged on the roller 63 . The discs 66 on two adjacent groups of rollers 63 are arranged in a staggered manner.

[0043] Through the above technical solution, the steel plate is moved toward one side of the conveying platform 61 by the inclined rollers 63 and discs 66, and the initial positioning of the steel plate is completed, so that the steel plate is conveyed to the bottom of the laser cutting assembly 62 along one side in a straight line. At the same time, multiple discs 66 are arranged on the rollers 63 to reduce the contact area with the steel plate and effectively protect the surface of the steel plate. At the same time, the gaps between adjacent discs 66 facilitate the falling of waste after laser cutting.

[0044] Furthermore, the side guard assembly 64 is located on one side of the interior of the conveying platform 61, and the side guard assembly 64 includes a push plate 641, a connecting rod assembly 642 and a push-pull cylinder 643; the length of the push plate 641 is adapted to the length of the conveying platform 61, and multiple groups of the connecting rod assemblies 642 are evenly arranged along the conveying direction, one end of the connecting rod assembly 642 is hinged to the push plate 641, and the other end of the connecting rod assembly 642 is hinged to the side plate of the conveying platform 61, the cylinder seat of the push-pull cylinder 643 is fixed on the side plate of the conveying platform 61, and the piston rod of the push-pull cylinder 643 is hinged to the middle part of the connecting rod assembly 642.

[0045] Through the above technical solution, the piston rod of the push-pull cylinder 643 drives the connecting rod assembly 642 to move, which is then converted into horizontal movement of the push plate 641. Through the push-pull cylinder 643 and the connecting rod assembly 642, the push plate 641 can push the steel plate to abut against the side plate of the conveying platform 61 on the opposite side to complete the limiting and clamping.

[0046] Furthermore, the limit assembly 65 is located on the discharge end side of the conveying platform 61, and the limit assembly 65 includes a limit rod, a telescopic assembly and a pressure sensor. The telescopic assembly is located at the bottom of the limit rod, and the pressure sensor is located at the top of the limit rod facing the incoming material side.

[0047] Through the above technical solution, the limit rod extends out of the highest point of the disc 66. When the steel plate abuts against the limit rod, the pressure sensor receives a signal, causing the roller 63 to stop rotating, and then the side guard assembly 64 and the laser cutting assembly 62 work. When the steel plate cutting is completed, the limit rod moves down through the telescopic assembly to ensure that the steel plate smoothly enters the discharge belt 7.

[0048] Furthermore, the laser cutting machine 6 is a three-beam 55 laser cutting machine 6, the laser cutting machine 6 is slidably connected to the conveying platform 61, and a guide plate 644 is provided on the inner side of one end of the push plate 641 close to the discharge end, and the guide plate 644 is a V-shaped structure.

[0049] Through the above technical solution, the front end of the steel plate will be pressed to a horizontal state by the guide plate 644 to prevent the front end of the steel plate from colliding with the laser cutting assembly 62, thereby ensuring processing safety. At the same time, the three-beam 55 laser cutting machine 6 has three sets of laser cutting assemblies 62, which can simultaneously cut a plate on the conveying platform 61 or multiple plates at the same time, greatly improving processing efficiency.

[0050] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
