Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and in particular to an automatic feeding device for steel sheets. Background Technology

[0002] Steel sheets are sheet-like steel materials made from steel plates through processes such as cutting and stamping. They are widely used in the automotive, electronics, and machinery industries, such as steel backing for automotive brake pads and steel sheets for motor cores. Their dimensional accuracy and surface condition directly affect the performance of the end products. Steel sheets need to be fed into the production line through a feeding device to solve the problems of low efficiency and easy placement deviation due to fatigue of manual feeding, thus avoiding affecting the accuracy of subsequent processing. Automated feeding devices can achieve continuous and orderly supply of steel sheets, avoid production line interruptions, and improve production efficiency.

[0003] For example, Chinese Patent No. CN223254108U discloses a steel sheet feeding mechanism, including a mounting frame, a steel sheet feeding rack, a steel sheet transfer assembly, and a steel sheet conveying assembly. The mounting frame is used to install the various components, and at least one set of steel sheet feeding racks is installed on the mounting frame. The steel sheet feeding racks are used to install steel sheets and can move back and forth. The steel sheet transfer assembly is located above the steel sheet feeding racks and is used to transfer the steel sheets to the next work station. The steel sheet conveying assembly includes a steel sheet mounting track and a steel sheet conveyor. The steel sheet mounting track is installed parallel to one side of the steel sheet feeding rack, and the steel sheets in the steel sheet mounting track are transferred by the steel sheet conveyor.

[0004] Currently, the material handling process of automatic steel sheet feeding equipment generally relies on two mainstream modes: magnetic attraction or compressed air adsorption. However, the stability of material handling in practical applications urgently needs to be improved. On the one hand, during storage and circulation, steel sheets need to be uniformly sprayed with anti-rust oil to prevent corrosion. The oil film not only reduces the magnetic conduction efficiency of the magnetic attraction device, but also creates an oil film adsorption force and vacuum effect between adjacent steel sheets, resulting in the steel sheets sticking tightly together. On the other hand, compressed air adsorption is easily affected by air pressure fluctuations. When a small sealing area appears on the surface of the steel sheet due to the oil film, it will form an additional adsorption effect. The combination of these two factors causes the existing material handling method to frequently grab multiple stacked steel sheets at a time. After these unseparated steel sheets are directly put into the production line, they will cause problems such as mold jamming in subsequent stamping processes and positioning deviations in assembly processes. This will not only interrupt continuous production, but may also cause equipment damage, increase product defect rate and production maintenance costs. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Firstly, in this invention, a lifting platform is connected via a lifting mechanism. Steel sheets are stacked on the lifting platform, and the lifting mechanism is used to raise the steel sheets from the placement slot into the through hole. This process is achieved by the meshing transmission of the driving gear and driven gear driven by the first motor, which drives the first shaft and the first worm gears on both sides to rotate. In turn, the first worm wheel and the second shaft drive the first lead screw to rotate, so that the first screw block carries the lifting platform to rise and fall smoothly. With the sliding guidance of the first guide block in the first guide groove, the rising accuracy of the steel sheets is ensured. The V-shaped baffle in the through hole limits the steel sheets from both sides, and its V-shaped structure can adapt to different... The wide steel sheet effectively prevents the steel sheet from deviating, providing a stable foundation for the hooking mechanism to accurately pick up the material. At the same time, the first cylinder in the limit component drives the stop block to move. Combined with the thickness detector monitoring the position of the stop block, the height of the stop block can be precisely controlled according to the thickness of the steel sheet. This ensures that when the lifting platform rises, only the topmost single steel sheet can reach the hooking position. The stop block prevents subsequent steel sheets from rising further, thus preventing the hooking mechanism from picking up too much material from the source. This solves the problem of multiple pieces being grabbed due to the adsorption of stacked steel sheets in traditional devices, ensuring that only a single steel sheet enters the production line each time, reducing the risk of mold jamming and positioning deviation in subsequent processes.

[0016] Secondly, in this invention, by setting an adjustment mechanism, the position of the hook block can be adjusted to accommodate steel sheets of different thicknesses. During adjustment, the second motor drives the second worm gear to rotate, which in turn drives the second lead screw to rotate, causing the second screw block to slide within the assembly frame. This causes the adjustment block and the bottom hook block to move synchronously. The sliding of the second guide block within the second guide groove further enhances the adjustment stability. The scale on one side of the adjustment block can visually display the adjustment distance, facilitating precise control of the hook block spacing by the operator. This ensures that the hook block can fit the edge of steel sheets of different specifications, achieving stable hooking. This flexible adjustment method allows the device to adapt to the production needs of various steel sheets without requiring a complete replacement of parts. It breaks the dependence of traditional feeding devices on a single specification of steel sheet, significantly improving the flexibility and applicability of the device, reducing the equipment investment costs incurred by enterprises due to changes in production specifications, and enhancing the versatility of the equipment.

[0017] Thirdly, the material is picked up by hooking instead of the traditional magnetic or adsorption method, which fundamentally avoids the interference of the anti-rust oil film on the surface of the steel sheet. In the hooking mechanism, the second cylinder drives the linkage plate to slide along the slide rail, and the hooking block moves along the trajectory formed by the first guide groove and the second guide groove to achieve mechanical hooking from below the edge of the steel sheet. It is not affected by the magnetic force attenuation or additional adsorption force caused by the oil film, and the material picking stability is significantly improved. The hooked steel sheet is transferred to the inclined guide plate and automatically slides down to the next station with the help of gravity. The guide groove ensures the stability of the steel sheet conveying trajectory and avoids deviation. The entire feeding process realizes the coordinated linkage of lifting, limiting, hooking and guiding through the controller. The degree of automation is high, reducing manual intervention, improving feeding efficiency, and reducing the production risk caused by human operation error. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10 In this embodiment of the invention, an automatic steel sheet feeding device includes a fixed platform 1. Placement slots 2 are provided on both sides of one end of the fixed platform 1. Through holes 3 are provided on both sides of the top of the fixed platform 1, communicating with the placement slots 2. V-shaped baffles 301 are fixedly connected to both sides of the interior of each through hole 3. A fixed frame 6 is fixedly connected to one side of the interior of the placement slot 2. A lifting mechanism 7 is provided on one side of the fixed frame 6. A lifting platform 5 is slidably connected to one side of the fixed frame 6 via the lifting mechanism 7, and the lifting platform 5 is slidably connected inside the placement slot 2. Steel sheets are stacked on top of the lifting platform 5. An mounting plate 10 is fixedly connected to the top of the fixed platform 1 above the two through holes 3. A limiting component 11 is provided on one side of the mounting plate 10 above the V-shaped baffles 301. A hooking mechanism 12 is provided on one side of the fixed platform 1. An adjusting mechanism 15 is provided on one side of the hooking mechanism 12. A guide plate 18 is fixedly connected to the rear of the fixed platform 1, so the guide plate 18 is located at the linkage plate 122. On the lower side, the guide plate 18 is inclined, and guide grooves are provided on both sides of the top of the guide plate 18. The inclined structure can automatically slide down with the weight of the steel sheet itself, without the need for additional power. The guide grooves can guide the steel sheet conveyed by the hooking mechanism 12, ensuring that the steel sheet enters the subsequent processing station along a fixed trajectory, and avoiding the steel sheet from deviating during the conveying process. A controller 4 is fixedly connected to one side of the fixed platform 1. The hooking material picking method replaces the traditional magnetic or adsorption material picking method, fundamentally avoiding the steel sheet deviating from the material picking process. The oil film on the surface of the steel sheet interferes with the stability of material feeding. The lifting mechanism 7 precisely controls the rising height of the steel sheet, and the limiting component 11 provides double constraint on the steel sheet, ensuring that the hooking mechanism 12 only grabs a single steel sheet at a time, effectively solving the problem of multiple sheets being stacked. At the same time, the adjusting mechanism 15 can flexibly adapt to steel sheets of different thicknesses. The structural design of the V-shaped baffle plate 301 and the guide plate 18 ensures that the steel sheet does not deviate during the flow process. Overall, the steel sheet is fed continuously, accurately, and stably, significantly improving production line efficiency and reducing equipment failure and product defect rate.

[0031] Please see Figure 6-7The lifting mechanism 7 includes a first motor 71, which is fixedly connected to one side of the interior of the fixed platform 1. A drive gear 72 is fixedly connected to the output end of the first motor 71. A driven gear 73 is meshed with one side of the drive gear 72. A first shaft 74 is fixedly connected to one side of the driven gear 73. The first shaft 74 is rotatably connected to one side of the interior of the fixed platform 1. First worm gears 75 are fixedly connected to both sides of the first shaft 74. A first worm wheel 76 is meshed with one side of the first worm gear 75. A second shaft 77 is fixedly connected to one side of the first worm wheel 76. The second shaft 77 is rotatably connected to the interior of the fixed platform 1. A first lead screw 78 is fixedly connected to the top of the second shaft 77. The first lead screw 78 is rotatably connected to the interior of the fixed frame 6. A first screw block 79 is threaded onto the outer surface of the first lead screw 78. The first screw block 79 is slidably connected to the interior of the fixed frame 6. One side of the first screw block 79 is fixedly connected to one side of the lifting platform 5. First guide grooves 8 are provided on both sides of the interior of the fixed frame 6. An internal sliding connection is provided with a first guide block 9, which is fixedly connected to both sides of the lifting platform 5. During operation, the controller 4 starts the first motor 71, and the output end of the first motor 71 drives the drive gear 72 to rotate. The drive gear 72 drives the meshing driven gear 73 to rotate, which in turn drives the first shaft 74 to rotate synchronously. The first worm gears 75 on both sides of the first shaft 74 rotate accordingly and drive the meshing first worm wheel 76, causing the second shaft 77 to drive the first lead screw 78 at the top to rotate. When the first lead screw 78 rotates, the first screw block 79 connected to the outer surface threaded along... The fixed frame 6 slides inside, driving the lifting platform 5 to rise and fall synchronously. The first guide blocks 9 on both sides of the lifting platform 5 slide in the first guide groove 8, precisely guiding the movement trajectory of the lifting platform 5. This mechanism achieves a speed reduction and torque increase effect through a multi-stage transmission structure of gears, worm gears and worm wheels, making the lifting process of the lifting platform 5 smooth and powerful. Combined with the guiding effect of the guide blocks and guide grooves, it ensures the lifting accuracy of the lifting platform 5, and can stably push the stacked steel sheets to the designated picking height, providing a foundation for the precise picking of materials by the hooking mechanism 12, and avoiding picking failure or multiple pieces being grabbed due to steel sheet height deviation.

[0032] Please see Figure 4The limiting component 11 includes a first cylinder 112, which is fixedly connected to one side of the mounting plate 10. Two first cylinders 112 are provided. A stop block 113 is fixedly connected to the output end of each first cylinder 112. One side of the stop block 113 is in movable contact with one side of the V-shaped baffle plate 301. A thickness sensor 111 is fixedly connected to the mounting plate 10 near the first cylinder 112, and the thickness sensor 111 monitors the position of the stop block 113. When the lifting mechanism 7 drives the steel sheet to rise... When the steel sheet reaches the through hole 3, the uppermost steel sheet is blocked by the stop block 113, allowing only a single steel sheet to be in a position that can be grabbed by the hooking mechanism 12. This component is driven by a cylinder to quickly adjust the position of the stop block 113. With the precise monitoring of the thickness detector 111, it can adapt to the limiting requirements of steel sheets of different thicknesses, effectively preventing the steel sheet from rising too high and causing multiple sheets to be stacked and grabbed. At the same time, the stop block 113 and the V-shaped baffle plate 301 work together to form a lateral constraint on the steel sheet, preventing the steel sheet from shifting during material picking and improving material picking stability.

[0033] Please see Figure 4 and Figure 8 The material-hooking mechanism 12 includes a second cylinder 121, which is fixedly connected to the upper interior of the fixed platform 1. Two second cylinders 121 are provided and are perpendicular to the first cylinder 112. A linkage plate 122 is fixedly connected to the output ends of the two second cylinders 121. Material-hooking blocks 123 are installed on both sides of the bottom end of the linkage plate 122 via an adjustment mechanism 15. A slide rail 124 is fixedly connected between the two second cylinders 121 inside the fixed platform 1. A groove 125 is provided in the middle of the bottom end of the linkage plate 122, and the linkage plate 122 is slidably connected to the slide rail 124 via the groove 125. When the steel sheet is pushed to the designated position by the lifting mechanism 7, the controller 4 activates the second cylinder 121, and the cylinder output end pushes the linkage plate 121. 2. Slide along the slide rail 124, and the hook block 123 at the bottom of the linkage plate 122 moves accordingly, hooking a single steel sheet from below the edge of the steel sheet. Then, the second cylinder 121 drives the linkage plate 122 to move in the opposite direction, taking the steel sheet out of the through hole 3 and transferring it above the guide plate 18. After the material taking action is completed, the hook block 123 resets. This mechanism uses a dual-cylinder synchronous drive for the linkage plate 122, and with the guide structure of the slide rail 124 and the slide groove 125, it ensures that the linkage plate 122 moves smoothly and accurately. The material taking method of the hook block 123 uses mechanical hooking force to act on the edge of the steel sheet, which is not affected by the oil film on the surface of the steel sheet, avoiding the problem of multiple pieces being grasped by the traditional adsorption method. At the same time, the hooking action is continuous and efficient, and can cooperate with the lifting mechanism 7 and the limit component 11 to ensure a stable feeding rhythm.

[0034] Please see Figure 4The guide plate 18 has a first guide groove 13 on one side, and there are two first guide grooves 13. The fixed platform 1 has second guide grooves 14 on both sides of its interior. The second guide grooves 14 are connected to the through hole 3. The first guide groove 13 is connected to the second guide groove 14. The hook block 123 is slidably connected to the first guide groove 13 and the second guide groove 14 respectively. During the material picking and feeding process, the hook block 123 always slides along the trajectory formed by the second guide groove 14 and the first guide groove 13. When the hook block 123 hooks the steel... When the sheet is removed from the through hole 3, the second guide groove 14 guides it to prevent the hook block 123 from shifting and causing the steel sheet to fall off. When the hook block 123 moves the steel sheet above the guide plate 18, the first guide groove 13 ensures that the hook block 123 transitions smoothly, so that the steel sheet falls accurately into the guide groove of the guide plate 18. This provides full-process guidance for the hook block 123, further improving the accuracy and stability of the hooking action, avoiding positional shift or falling of the steel sheet during the transfer process, and ensuring the smooth flow of the steel sheet from the picking position to the guiding position.

[0035] Please see Figure 7-8The adjusting mechanism 15 includes an assembly frame 151, which is fixedly connected to both sides of one end of the linkage plate 122. A second motor 152 is fixedly connected to one side of the assembly frame 151. A second worm gear 153 is fixedly connected to the output end of the second motor 152. A second worm wheel 154 is meshed with one side of the second worm gear 153. A second lead screw 155 is fixedly connected to one side of the second worm wheel 154. The second lead screw 155 is rotatably connected to one side of the assembly frame 151. The outer surface of the second lead screw 155 is threaded. A second screw block 156 is connected to the assembly frame 151. One side of the second screw block 156 is slidably connected to the inside of the assembly frame 151. An adjusting block 157 is connected to the bottom end of the second screw block 156. One side of the adjusting block 157 slides through the assembly frame 151. A scale 1571 is embedded in one side of the adjusting block 157. The bottom end of the adjusting block 157 is fixedly connected to the top end of the hook block 123. A plug rod 158 is fixedly connected to the top end of the adjusting block 157. One side of the plug rod 158 passes through the second screw block 156 and is secured by a fixing bolt 159. The assembly frame 151 is fixedly connected to the assembly frame 151. Second guide grooves 16 are provided on both sides of the assembly frame 151. Second guide blocks 17 are slidably connected inside the second guide grooves 16, and the second guide blocks 17 are fixedly connected to both sides of the second screw block 156. When the second motor 152 is started, the motor output drives the second worm gear 153 to rotate, which in turn drives the meshing second worm wheel 154 to rotate the second lead screw 155. The second screw block 156 slides along the inside of the assembly frame 151, causing the adjusting block 157 to move synchronously. The hook block 12 can be observed through the scale 1571 on one side of the adjusting block 157. The adjustment distance of 3 is adjusted so that the spacing of the hook blocks 123 is adapted to the size of the steel sheet. The motor is then turned off to complete the adjustment. This mechanism achieves fine adjustment of the position of the hook blocks 123 through the transmission structure of the worm gear and the lead screw. The second guide block 17 and the second guide groove 16 ensure a smooth and accurate adjustment process. The scale 1571 allows the operator to intuitively control the adjustment accuracy. The cooperation between the insertion rod 158 and the fixing bolt 159 facilitates the subsequent replacement of the adjustment block 157 and the hook blocks 123, which greatly improves the device's adaptability to steel sheets of different specifications and enhances the flexibility and versatility of the equipment.

[0036] The working principle of this invention is as follows: First, the equipment is initialized. The operator neatly stacks the steel sheets to be loaded onto the lifting platform 5 in the placement slots 2 at both ends of the fixed platform 1, ensuring that the edges of the steel sheets are in contact with the lifting platform 5. Then, the controller 4 starts the equipment self-test program to confirm that the lifting mechanism 7, the limit component 11, the hooking mechanism 12, and the adjustment mechanism 15 are all in the initial standby state. At the same time, it is checked that there are no debris blocking the guide groove of the guide plate 18 to ensure that the steel sheet conveying channel is unobstructed. Then, targeted adjustments are made according to the thickness and size parameters of the steel sheets to be loaded. When adjusting the limit component 11, the controller 4 receives the reference signal from the thickness detector 111 and drives the two first cylinders 112 on the mounting plate 10 to move, driving the stop block 113 along the V-shaped stop plate 301. The material is moved laterally until the gap between the stop block 113 and the V-shaped baffle plate 301 is exactly equal to the thickness of a single steel sheet. The thickness detector 111 provides real-time feedback on the position data of the stop block 113 to ensure adjustment accuracy. When adjusting the hooking mechanism 12, the second motor 152 of the adjustment mechanism 15 is started. The motor drives the second worm gear 153 to rotate, which in turn drives the second lead screw 155 to rotate through the second worm wheel 154, causing the second screw block 156 to slide along the inside of the assembly frame 151. This causes the adjustment block 157 and the hooking block 123 at the bottom to move synchronously. The operator can visually read the spacing of the hooking blocks 123 through the scale 1571 on one side of the adjustment block 157 until the position of the hooking block 123 can accurately fit the bottom edge of the steel sheet. After the adjustment is completed, the second motor 152 stops running, and the second guide block... The sliding within the second guide groove 16 ensures the smoothness of the adjustment process. After the equipment is adjusted, it enters the automatic feeding stage. The controller 4 issues a command to start the first motor 71 of the lifting mechanism 7. The motor output drives the drive gear 72 to rotate, which in turn drives the first shaft 74 to rotate through the meshing driven gear 73. The first worm gears 75 on both sides of the first shaft 74 rotate synchronously and drive the meshing first worm wheel 76, causing the second shaft 77 to drive the first lead screw 78 at the top to rotate. The first screw block 79 slides along the fixed frame 6 and drives the lifting platform 5 to rise. The first guide blocks 9 on both sides of the lifting platform 5 guide the steel sheet within the first guide groove 8, ensuring that the steel sheet rises smoothly into the through hole 3. The V-shaped baffle plate 301 limits the steel sheet from both sides. Its V-shaped structure adapts to the width of the steel sheet, preventing the steel sheet from being blocked. If the steel sheet deviates from its course, the lifting mechanism 7 stops operating when the uppermost steel sheet contacts the stop block 113. At this time, the second cylinder 121 of the hooking mechanism 12 starts, pushing the linkage plate 122 to slide along the slide rail 124. The hook block 123 moves along the trajectory formed by the second guide groove 14 and the first guide groove 13, mechanically hooking the steel sheet from below its edge. Then, the second cylinder 121 drives the linkage plate 122 to move in the opposite direction, transferring the steel sheet to the guide plate 18 above the rear side of the fixed platform 1. During the resetting process of the hook block 123, the steel sheet detaches from the hook and falls into the guide groove. With the help of the inclined structure of the guide plate 18 and its own gravity, it slides along the guide groove to the next station. After a single steel sheet is transferred, the lifting mechanism 7 starts again, driving the steel sheet to rise, repeating the above material picking and feeding process to achieve continuous automated feeding.The material-grabbing method, replacing traditional magnetic or adsorption-based methods, fundamentally avoids the interference of the anti-rust oil film on the steel sheet surface. Traditional magnetic methods are prone to reduced magnetic force transmission efficiency due to the oil film, and compressed air adsorption is easily affected by air pressure fluctuations and the sealing area of ​​the oil film. However, the hook block 123 acts on the edge of the steel sheet through mechanical force, and is not affected by the magnetic force attenuation or additional adsorption force caused by the oil film. The material-grabbing stability is greatly improved, and the problem of frequently grabbing multiple steel sheets at a time in traditional devices is completely solved. This avoids problems such as mold jamming in subsequent stamping processes and positioning deviations in assembly, reducing the frequency of production line interruptions and equipment damage. This reduces the risk of injury, lowers product defect rates and production and maintenance costs. The coordinated design of the lifting mechanism 7 and the limit component 11 enables precise height control and single-piece limit of the steel sheets. The stop block 113 of the limit component 11 works in conjunction with the thickness detector 111 to adjust the limit height in real time according to steel sheets of different thicknesses, ensuring that only one steel sheet reaches the picking position at a time, avoiding multiple sheets being picked up at the source, and ensuring feeding accuracy. This device has a high degree of automation, reducing manual intervention, which not only improves feeding efficiency but also reduces the production risks caused by human error, enabling steel sheets to be supplied to the production line continuously and orderly, avoiding production line interruptions.
