Description

Technical Field

[0001] The invention relates to the technical field of laser blanking production lines, in particular to an automatic laser blanking production line capable of automatically loading materials. Background Art

[0002] When coils are produced and processed, CNC uncoiling, leveling and laser blanking production lines are often used for continuous processing. The current CNC uncoiling, leveling and blanking production lines are usually composed of industrial robots, levelers, uncoiling machines and laser cutting equipment. They mainly complete the uncoiling, leveling, cutting and blanking processes to achieve rapid production and processing of coils.

[0003] According to a publicly disclosed CNC unwinding and leveling laser blanking production line with accurate positioning (Announcement No.: CN218396879U), the support body of the device is fixed to the first support block by bolts, so as to facilitate the rapid disassembly and assembly of the roller and the rapid replacement of the coil.

[0004] However, in the actual use of the above equipment, due to the high production efficiency of the automated production line, the coil is consumed quickly, and the coil itself has a large mass. Frequent lifting and loading of the coil and fixing it in the automated production line will waste a lot of production time and reduce the operating efficiency of the entire automated production line. In view of this, we propose a laser blanking automated production line that can automatically load materials. Summary of the invention

[0011] Preferably, the toggle plate is adapted to the curvature of the movable cavity, and the telescopic sleeves and the abutting springs are provided in two groups, and the two groups of telescopic sleeves and the abutting springs are symmetrically arranged with the vertical central axis of the toggle plate as the symmetry axis.

[0012] Preferably, a telescopic groove matched with the contact arc plate is provided between the movable cavity and the transmission cavity, and the contact arc plate is arranged inside the telescopic groove. In addition, the protruding portion of the convex cylinder is arranged on the side close to the feed slide, so that as the rotating drum rotates, the toggle plate that moves to the side close to the feed slide is affected by the contact arc plate on its top and tends to be pushed outward, thereby first splitting the gaps between the coiled material drums arranged on the feed slide.

[0016] Compared with the prior art, the present invention provides an automatic laser blanking production line with automatic loading, which has the following beneficial effects: 1. The automatic production line for laser blanking with automatic feeding is provided with a feeding limiting component. When feeding is required, the stepper motor is started, so that when the stepper motor drives the turntable to rotate, it is affected by the driving wheel, driven wheel, driving gear and driven gear of the same diameter. The rotating drum and the turntable have the same speed and opposite directions. The arc plate is used to divert the coiled material drum on the feeding slide so that it can correspond to the chute on the turntable. Due to the arc setting of the arc plate, the automatic feeding work is completed without causing the subsequent coiled material drum to be stuck, thereby ensuring the normal feeding of subsequent materials.

[0017] 2. The laser blanking automated production line with automatic loading is provided with a splitting component. As the rotating drum rotates, the toggle plate that moves to the side close to the feed slide is affected by the contact arc plate on its top and tends to be pushed outward, thereby first splitting the gaps between the coiled drums arranged on the feed slide to separate the two. The coiled drum at the bottom can smoothly enter the loading area and enter the chute as the turntable rotates to complete the loading, thereby avoiding the situation where the coiled drums are piled up and excessive unloading occurs easily.

[0018] 3. The automatic production line for laser blanking with automatic loading is provided with a correction component. When the toggle plate is extended out of the toggle arc plate by the outward ejecting force of the contact arc plate, the correction slider is pulled upward due to the setting of the pull rope, so that it is driven by the inclined guide groove and moves toward the two ends of the toggle plate, so that the coiled material drum in contact with the correction slider is also driven to both sides, thereby prompting the coiled material drum to be corrected in the center during loading, ensuring its stable loading and further ensuring the safe production operation of the automatic production line.

DETAILED DESCRIPTION

[0021] like Figure 1-Figure 9As shown, the present invention provides a technical solution: an automatic production line for laser blanking capable of automatic loading, comprising a workbench 1, an upper surface of the workbench 1 is provided with an automated processing device 2, a main loading platform 3 is fixedly installed at the end of the workbench 1, an auxiliary loading platform 4 is fixedly installed at one end of the main loading platform 3 away from the workbench 1, a feed slide 5 is fixedly installed on the upper surface of the auxiliary loading platform 4, a feed limiting component 6 is provided on the top of the main loading platform 3 for buffering, limiting and diverting the coiled material continuously unloaded from the feed slide 5, the feed limiting component 6 comprises a vertical plate 61, a stepping motor 62, a turntable 63, a coil drum 64, a driving wheel 65, a transmission belt 66, a driven wheel 67, a driving gear 68, a support plate 69, a driven gear 610, a rotating drum 611 and a toggle arc plate 612.

[0022] In one embodiment of the present invention, a vertical plate 61 is fixedly installed on the top of the main loading platform 3, a stepper motor 62 is fixedly installed on the side wall of the vertical plate 61, a turntable 63 is fixedly installed on the output end of the stepper motor 62, a coil drum 64 is detachably connected to the side of the turntable 63, a driving wheel 65 is coaxially fixedly installed on the turntable 63, the driving wheel 65 is connected to a driven wheel 67 through a transmission belt 66, a driving gear 68 is coaxially fixedly installed on the driven wheel 67, a support plate 69 is fixedly installed on the upper surface of the main loading platform 3, a driven gear 610 is rotatably installed on the side wall of the support plate 69, a rotating drum 611 is coaxially fixedly installed on the driven gear 610, and a toggle arc plate 612 is fixedly installed on the arc-shaped outer wall of the rotating drum 611.

[0023] Furthermore, the working table 1, the main loading platform 3 and the auxiliary loading platform 4 are arranged linearly, so that the automatic loading of the coil can be carried out smoothly, thereby ensuring the production efficiency of the laser blanking automatic production line. At the same time, the feeding slide 5 is arranged in an inclined shape close to the end of the main loading platform 3, so that after an external robot or manual loading puts the coil onto the end of the feeding slide 5 away from the main loading platform 3, it can gradually roll to the side close to the main loading platform 3 under the action of gravity, thereby facilitating subsequent automatic loading work. In addition, there are two groups of vertical plates 61, and the two groups of vertical plates 61 are symmetrically arranged with the vertical central axis of the main loading platform 3 as the symmetry axis, thereby providing a stable supporting force for the turntable 63, thereby facilitating the loading of the coil drum 64. Specifically, a portion of the outer wall of the turntable 63 close to the center of the main loading platform 3 is provided with a connection with the end of the coil drum 64 The chute is adapted to the connecting shaft, and four groups of chutes are arranged on the side of the turntable 63, so that four groups of coil drums 64 can exist on the side of the turntable 63 at the same time, thereby ensuring that the automated processing equipment 2 can continuously obtain the coil raw materials without a long pause when switching the coil drum 64, affecting the processing efficiency of the automated production line. At the same time, when the chute rotates to approach the feed slide 5, the bottom inner surface of the chute is kept flush with the lower surface of the feed slide 5, so that the coil drum 64 on the feed slide 5 can smoothly enter the chute under the action of gravity, and locking buckles are arranged on the side walls of the turntable 63. When the coil drum 64 moves to the bottom of the chute, it is affected by the locking buckle and locked, thereby avoiding the coil drum 64 from slipping when the turntable 63 rotates, affecting the normal production work of the automated production line.

[0024] Specifically, the driving wheel 65 and the driven wheel 67 have the same outer diameter, and the driving gear 68 and the driven gear 610 have the same outer diameter. Therefore, when the stepper motor 62 drives the turntable 63 to rotate, it is affected by the driving wheel 65, the driven wheel 67, the driving gear 68 and the driven gear 610 with the same diameter. The rotating drum 611 has the same rotation speed and opposite direction as the turntable 63. At the same time, there are four groups of shifting arc plates 612, which correspond to the four groups of chutes on the side of the turntable 63. When the turntable 63 rotates, the rotating drum 611 can rotate in the opposite direction synchronously, and cooperate with the shifting arc plate 612 to divert the coil drum 64 on the feeding slide 5 so that it can correspond to the chute on the turntable 63. In addition, due to the arc setting of the shifting arc plate 612, it will not cause the subsequent coil drum 64 to get stuck, thereby ensuring the normal feeding of subsequent materials.

[0025] In addition, a splitting component 7 is provided inside the rotating drum 611 to assist in the accurate feeding of the coiled material. The splitting component 7 includes an active cavity 71. The active cavity 71 is opened inside the toggle arc plate 612. A toggle plate 72 is slidably installed on the inner surface of the active cavity 71. A telescopic sleeve 73 is fixedly connected between the top of the toggle plate 72 and the top inner wall of the active cavity 71. A tightening spring 74 is sleeved on the arc-shaped outer wall of the telescopic sleeve 73. A contact arc plate 75 is fixedly installed on the top of the toggle plate 72. A transmission cavity 76 is opened on the inner wall of the rotating drum 611. A fixing rod 77 is fixedly installed on the side wall of the support plate 69. The fixing rod 77 passes through and is fixedly installed with a convex cylinder 78.

[0026] When the cam 72 is in the closed position, the spring 74 will move in a direction opposite to the start position of the lever 72. When the cam 72 is in the closed position, the lever 72 will move in a direction opposite to the start position of the lever 72. When the cam 72 is in the closed position, the lever 72 will move in a direction opposite to the start position of the lever 72. There is a telescopic groove that is compatible with the contact arc plate 75, and the contact arc plate 75 is arranged inside the telescopic groove. In addition, the protruding part of the convex cylinder 78 is arranged on the side close to the feed slide 5, so that as the rotating drum 611 rotates, the toggle plate 72 that moves to the side close to the feed slide 5 is affected by the contact arc plate 75 on its top and tends to be pushed outward, and then the gap between the coiled tubes 64 arranged on the feed slide 5 is first split to separate the two. The coiled tube 64 at the bottom can smoothly enter the loading area and enter the chute as the turntable 63 rotates to complete the loading, thereby avoiding the situation where the coiled tubes 64 are piled up and excessive unloading is easy to occur.

[0027] At the same time, a correction component 8 that can adjust the center of the coil is provided inside the toggle plate 72, and the correction component 8 includes a tension spring 81, and the end of the tension spring 81 is fixedly connected to the inner wall of the active cavity 71, and the other end of the tension spring 81 is fixedly connected to an arc-shaped slide plate 82, and the end of the arc-shaped slide plate 82 away from the tension spring 81 is fixedly connected to a pull rope 83, and the end of the pull rope 83 away from the arc-shaped slide plate 82 is fixedly connected to a correction slider 84, and a guide inclined groove 85 is provided on the side wall of the toggle plate 72, and a deflection groove 86 is provided on the outer wall of the side of the correction slider 84 away from the guide inclined groove 85, and a rotating rod 87 is rotatably installed on the inner wall of the deflection groove 86, and a shift block 88 is passed through and fixedly installed on the rotating rod 87, and a spiral spring 89 is sleeved on the arc-shaped outer wall of the rotating rod 87.

[0028] In an embodiment of the present invention, there are two groups of correction components 8, and the two groups of correction components 8 are symmetrically arranged with the vertical central axis of the toggle plate 72 as the symmetry axis, so that the coiled material drum 64 on the side of the toggle plate 72 can obtain a stable centering correction effect. At the same time, the guide inclined groove 85 is arranged in an inclined shape with one end lower near the center of the toggle plate 72, and a T-shaped groove is provided on the bottom inner wall of the guide inclined groove 85. At the same time, a T-shaped block adapted to the T-shaped groove is provided on the side wall of the correction slider 84 to prevent the correction slider 84 from falling off on the guide inclined groove 85. Furthermore, a circular hole with a diameter larger than the outer diameter of the spiral spring 89 is provided on the inner wall of the end of the deflection groove 86, and the spiral spring 89 The two ends are respectively fixedly connected to the inner wall of the bottom end of the circular hole and the arc-shaped outer wall of the rotating rod 87, so that the rotating rod 87 always has a tendency to rotate in the opposite direction to achieve reset when it rotates. When the toggle plate 72 is pushed outward by the contact arc plate 75 and extends out of the toggle arc plate 612, the correction slider 84 will be pulled upward due to the setting of the pull rope 83, so that it is driven by the inclined guide groove 85 and moves toward the two ends of the toggle plate 72, so that the coil drum 64 in contact with the correction slider 84 will also be driven to both sides, thereby prompting the coil drum 64 to be corrected in the center during loading, ensuring its stable loading, and then ensuring the safe production operation of the automated production line.

[0029] In the present invention, when in use, the coiled material drum 64 is sequentially dropped from the end of the feed slide 5 away from the main loading platform 3, and the stepper motor 62 is started, so that when the stepper motor 62 drives the turntable 63 to rotate, it is affected by the driving wheel 65, the driven wheel 67, the driving gear 68 and the driven gear 610 of the same diameter, and the rotating drum 611 has the same rotation speed and opposite direction as the turntable 63, and cooperates with the arc plate 612 to divert the coiled material drum 64 on the feed slide 5 so that it can correspond to the chute on the turntable 63, and due to the arc setting of the arc plate 612, the automatic loading work is completed without causing the subsequent coiled material drum 64 to be stuck, thereby ensuring the normal loading of subsequent materials.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
