[0001] This utility model relates to the field of automated processing technology, specifically to an automatic sheet metal feeding device. Background Technology

[0002] Sheet metal processing, as a fundamental link in manufacturing, is widely used in many fields such as chassis and cabinets, automotive parts, appliance housings, and architectural decoration. In the sheet metal production process, the feeding stage—that is, taking the metal sheets to be processed (such as cold-rolled sheets, stainless steel sheets, aluminum sheets, etc.) from the stack or warehouse and accurately and stably conveying them to the worktable of processing equipment such as punch presses, laser cutting machines, and bending machines—is used to achieve automatic feeding processing. Existing automatic feeding equipment, such as the invention patent with application publication number CN107891100A, discloses an automatic sheet metal feeding machine for power distribution cabinets, which achieves automatic feeding of sheet metal parts by setting up suction cups. However, the feeding accuracy cannot be guaranteed, and it requires a feeding flow line, which occupies a large space. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an automatic sheet metal feeding device that realizes automatic sheet metal feeding with high feeding accuracy, compact structure, and small space occupation.

[0004] Specifically, this utility model discloses an automatic sheet metal feeding device, comprising:

[0005] The loading hopper has multiple storage slots for storing sheet metal.

[0006] A material pulling device is located on one side of the feeding bin and has a pulling plate for pulling sheet metal out of the feeding bin;

[0007] The fixing device is used to fix the sheet metal after the pulling device pulls the sheet metal to the loading position;

[0008] A lifting device is connected to the material pulling device and the fixing device, and is used to drive the material pulling device and the fixing device to lift and lower.

[0009] The advantages of adopting the above technical solution are that it enables automatic feeding of sheet metal parts, with high feeding accuracy, lifting capability, applicability to various processing conditions, compact structure, and small space occupation.

[0010] Furthermore, the material pulling device includes: a base plate, a moving block, a guide rail, and a material pulling drive component. The guide rail is disposed on the base plate, the moving block moves along the guide rail, the material pulling plate is connected to the moving block, and the material pulling plate can be raised and lowered.

[0011] The advantage of adopting the above technical solution is that the pulling plate extends into the loading bin to pull out the sheet metal parts, and the setting of the moving guide rail makes the lifting and lowering smooth, ensuring that the material is pulled in place.

[0012] Furthermore, the material pulling plate is provided with a material pulling groove, and a pulling plate driving component is provided between the moving block and the material pulling plate, the pulling plate driving component driving the material pulling plate to rise and fall.

[0013] The advantage of adopting the above technical solution is that the pull groove is used to pull the sheet metal, and the liftable pull plate can pull and release, which facilitates loading.

[0014] Furthermore, the fixing device includes a fixing plate and a fixing drive component. The fixing drive component is connected to the fixing plate. The fixing plate is provided with a fixing groove. The fixing drive component drives the fixing plate to move horizontally, and the fixing groove fixes the sheet metal.

[0015] The advantage of adopting the above technical solution is that when the sheet metal reaches the loading position by being pulled by the pulling plate, the fixing plate moves and fixes the product through the fixing groove to prevent the product from moving, thus playing a limiting role, ensuring the position of the sheet metal, and facilitating subsequent transfer and processing.

[0016] Furthermore, the feeding hopper has a support frame, and symmetrically arranged receiving plates are provided inside the support frame. The receiving plates form a space to accommodate the sheet metal. A discharge position is provided on the lower side of the support frame for the material pulling device to pass through.

[0017] The advantage of adopting the above technical solution is that the receiving plate is set to receive the sheet metal, so that the sheet metal is stored and arranged in the feeding bin, and the sheet metal is discharged through the discharge position, realizing the transfer of sheet metal parts from the feeding bin to the feeding position.

[0018] Furthermore, the feeding hopper is equipped with a chain circulation structure, including a circulation chain, a motor, and a support frame. The support frame is installed inside the feeding hopper, and the receiving plate is connected to the circulation chain. The motor drives the circulation chain to rotate on the support frame, thereby driving the receiving plate to move cyclically.

[0019] The advantage of adopting the above technical solution is that it enables the receiving plate to rotate cyclically, driving the sheet metal parts to move continuously downward to the discharge position, thereby realizing automatic cyclic feeding.

[0020] Furthermore, the lifting device includes: a lower plate, a top plate, a middle plate, a guide rod, and a lifting drive assembly. The lower plate and the middle plate are connected by a support column. The bottom plate is located above the middle plate and slides along the guide rod. The top plate is connected to the bottom plate. The lifting drive assembly drives the top plate to rise and fall.

[0021] The advantage of adopting the above technical solution is that the top plate lifts the bottom plate, and the bottom plate rises along the guide rod under the control of the lifting drive component, which facilitates subsequent material receiving and transfer operations and is applicable to various processing lines.

[0022] Furthermore, the lifting drive assembly includes: a transmission chain, a cylinder, a connecting plate, a sliding plate, and a sprocket. The connecting plate is fixedly installed on the lower plate. The cylinder is installed on the connecting plate, and its output end is connected to the sliding plate. The sprocket is installed on the sliding plate. The transmission chain is installed in conjunction with the sprocket, with one end fixed to the connecting plate and the other end fixed to the top plate.

[0023] The advantages of adopting the above technical solution are that the transmission chain has a multi-section structure, which facilitates the installation and processing of parts, and can be adapted to products of different heights by adjusting the mechanism; the chain drive can bear a large load, which greatly expands the application range of this mechanism; in addition, the chain and sprocket mechanism transmission has higher precision than belt drive.

[0024] Furthermore, the upper and lower sides of the feeding hopper are provided with a width adjustment module for adjusting the spacing of the support frame, including: a symmetrically arranged width adjustment plate and a width adjustment drive component. The width adjustment plate is installed in the feeding hopper, and the width adjustment drive component drives the width adjustment plate to move closer to or further away from the feeding hopper.

[0025] The advantage of adopting the above technical solution is that it enables the spacing of the support frame to be adjusted, which allows for the storage of sheet metal of different widths and improves the overall practicality of the equipment.

[0026] Furthermore, support blocks are provided on both sides of the guide rail, the support blocks are arranged along the material pulling direction, and multiple rollers are provided on their tops.

[0027] The advantage of adopting the above technical solution is that the support block is used to support the sheet metal, while the rollers make the sheet metal move smoothly and protect the surface of the sheet metal. Attached Figure Description

[0040] The present invention will now be described in further detail with reference to the accompanying drawings.

[0041] like Figure 1-3 As shown, this utility model discloses an automatic sheet metal feeding device, comprising:

[0042] The loading bin 1 has multiple storage slots inside for storing sheet metal 11;

[0043] The material pulling device 2 is located on one side of the feeding bin 1 and has a material pulling plate 21 for pulling the sheet metal 11 out of the feeding bin 1.

[0044] Fixing device 3: After the material pulling device 2 pulls the sheet metal 11 to the loading position, the fixing device 3 is used to fix the sheet metal 11.

[0045] The lifting device 4 is connected to the pulling device 2 and the fixing device 3, and is used to drive the pulling device 2 and the fixing device 3 to lift.

[0046] The advantages of adopting the above technical solution are that it enables automatic feeding of 11 sheet metal parts with high feeding accuracy, can be raised and lowered, is suitable for various processing conditions, has a compact structure, and occupies little space.

[0047] Among them, such as Figure 4 As shown, the material pulling device 2 includes: a base plate 22, a moving block 23, a guide rail 24, and a material pulling drive component 25. The guide rail 24 is fixedly installed on the base plate 22 and is arranged along the material pulling direction. A slider is installed on the guide rail 24. The moving block 23 is fixed to the slider and moves along the guide rail 24. The material pulling plate 21 is connected to the moving block 23 and can be raised and lowered. The material pulling drive component 25 is a stepper motor. The base plate 22 is equipped with synchronous pulleys at both ends of the guide rail 24. A synchronous belt 29 is installed between the two synchronous pulleys. The moving block 23 is fixedly connected to the synchronous belt 29. The stepper motor drives the synchronous pulleys to rotate, which further drives the moving block 23 to move, causing the material pulling plate 21 to move and pull out the sheet metal 11 parts located in the loading bin 1 to the loading position. A stop block is installed on the base plate 22 to limit the position of the sheet metal 11. At the same time, a slotted photoelectric sensor is also installed on the base plate 22, and a sensing plate is installed on the moving block 23. When the photoelectric sensor detects the sensing plate, it indicates that the moving block 23 has reached the correct position.

[0048] Furthermore, the pull plate 21 is provided with a pull groove 211, which is vertically set on the lower surface of the pull plate 21. The sheet metal 11 to be loaded has a vertical bent edge. A pull plate drive component 26 is provided between the moving block 23 and the pull plate 21. The pull plate drive component 26 is a slide cylinder, which is vertically installed and drives the pull plate 21 to rise and fall. When the pull plate 21 needs to reach the pull position, the pull plate 21 falls, the pull groove 211 cooperates with the bent edge on the sheet metal 11, and the pull plate 21 moves horizontally. After the sheet metal 11 is moved into place, the pull plate 21 rises, and the moving block 23 continues to move outward a certain distance so that the pull plate 21 will not affect the picking up of the sheet metal 11.

[0049] Furthermore, support blocks 27 are provided on both sides of the guide rail 24. The support blocks 27 are arranged along the material pulling direction, and multiple rollers 28 are provided on their tops. The rollers 28 can be rolled and installed. The support blocks 27 are provided with mounting grooves, and the rollers 28 are installed inside them. The tops of the rollers 28 extend out from the surface of the support blocks 27, and the rollers 28 are arranged in two rows side by side.

[0050] In some embodiments, the fixing device 3 includes a fixing plate 31 and a fixing drive 32. The fixing drive 32 is connected to the fixing plate 31. The fixing plate 31 is provided with a fixing groove 33. The fixing drive 32 drives the fixing plate 31 to move horizontally. The fixing groove 33 fixes the sheet metal 11. The fixing drive 32 is also a slide cylinder, which is horizontally installed. Its bottom is installed with a pad between it and the base plate 22. There are four fixing plates 31, which are symmetrically arranged on both sides of the sheet metal. Under the drive of the fixing drive 32, they move horizontally and move towards the sheet metal 11. After the sheet metal 11 is in place, the fixing groove 33 fixes the sheet metal 11. When the sheet metal 11 is moved away from the sheet metal 11, the sheet metal 11 can be picked up, which plays the role of limiting and fixing.

[0051] In some implementations, the feeding hopper 1 has a support frame 12, and the feeding hopper 1 is surrounded by a perimeter panel. Symmetrically arranged receiving plates 13 are installed inside the support frame 12, forming a space between the receiving plates 13 to accommodate sheet metal 11. The receiving plates 13 have an L-shaped cross-section. The sheet metal 11 is placed between the symmetrically arranged receiving plates 13. Multiple rotatable rollers are also installed on the receiving plates 13 to prevent scratches on the sheet metal 11 during movement. A discharge position 14 is provided on the lower side of the support frame 12 for the feeding device 2 to pass through. The side of the feeding hopper 1 away from the feeding device 2 is open, and a light grating sensor 16 is installed on its lower side. The upper side is used for product passage, enabling manual or robotic loading of products. A proximity switch 15 is installed at the bottom of the feeding hopper 1 to sense whether there is sheet metal 11 inside the feeding hopper 1 and whether the sheet metal 11 is in place.

[0052] Furthermore, such as Figure 5 As shown, the feeding bin 1 is equipped with a chain circulation structure, including a circulation chain 5, a motor 51, and a support frame 52. The support frame 52 is installed in the feeding bin 1, and the receiving plate 13 is connected to the circulation chain 5. The motor 51 drives the circulation chain 5 to rotate on the support frame 52, which in turn drives the receiving plate 13 to move cyclically. The support frames 52 are symmetrically installed in the feeding bin 1, and two circulation chains 5 are installed in each support frame 52. The two ends of the receiving plate 13 are fixedly installed with the circulation chain 5. The circulation chain 5 is driven by the bracket sprockets 53 installed at the upper and lower ends of the support frame 52. The rotation of the bracket sprockets 53 is driven by the motor 51. The receiving plate 13 supports the sheet metal 11. The circulation chain 5 drives the sheet metal 11 to move downward. When it reaches the bottom, the sheet metal 11 is moved out of the feeding bin 1 by the pull plate 21. Then the circulation chain 5 continues to rotate, and the empty receiving plate 13 rotates to the rear of the support frame 52 and then reaches the upper side of the feeding bin 1 for feeding. The product is continuously fed in a cyclical manner to achieve continuous feeding.

[0053] The upper and lower sides of the feeding hopper are equipped with width adjustment modules for adjusting the spacing of the support frame 52. These modules include symmetrically arranged width adjustment plates 7 and width adjustment drive components 71. The width adjustment plates 7 are installed inside the feeding hopper. The top and bottom of the feeding hopper are equipped with hopper plates, and guide rails and sliders are installed on the hopper plates. The width adjustment plates 7 move along the sliders. The guide rails are arranged along the length of the sheet metal. The width adjustment drive component 71 is a cylinder, symmetrically arranged. Its main body is fixedly installed with the hopper plate, and its output end is connected to the width adjustment plates 7 to change the distance between the two width adjustment plates 7. The two ends of the support frame 52 are fixedly installed with the width adjustment plates 7. By changing the distance between the two width adjustment plates 7, the distance of the support frame is changed, so that the spacing of the symmetrically arranged receiving plates 13 can be adjusted, which is suitable for storing sheet metal parts of different sizes.

[0054] In some implementation schemes, such as Figure 6-9 As shown, the lifting device 4 includes: a lower plate 41, a top plate 42, a middle plate 43, a guide rod 44, and a lifting drive assembly. The lower plate 41 and the middle plate 43 are fixedly connected by support columns. The middle plate 43 and the bottom plate 22 are both equipped with guide sleeves. The guide rod 44 moves up and down within the guide sleeves. The bottom plate 22 is located on the upper side of the middle plate 43 and slides along the guide rod 44. The top plate 42 is connected to the bottom plate 22. The lifting drive assembly drives the top plate 42 to rise and fall. Limit blocks are provided at both ends of the guide rod 44. Under the drive of the top plate 42, when the bottom plate 22 rises to the highest distance, the guide sleeves on the middle plate 43 and the bottom plate 22 respectively contact the limit blocks at both ends of the guide rod 44. This is the maximum rising distance.

[0055] Furthermore, the lifting drive assembly includes: a transmission chain 6, a cylinder 61, a connecting plate 62, a sliding plate 63, and a sprocket 64. The connecting plate 62 is fixedly installed on the lower plate 41 and is vertically installed. The cylinder 61 is vertically fixedly installed on the connecting plate 62, and its output end is connected to the sliding plate 63. The connecting plate 62 is equipped with a guide rail and a slider, and the sliding plate 63 is fixed to the slider and moves up and down along the slider. The sprocket 64 is symmetrically installed on the top of the sliding plate 63. The transmission chain 6 is installed in conjunction with the sprocket 64, with one end fixed to the connecting plate 62 and the other end fixed to the top plate 42. A fixing member 65 is fixedly installed in the middle of the mounting plate and at the bottom of the top plate 42 for fixing to both ends of the transmission chain 6. During the upward movement of cylinder 61, sliding plate 63 is driven to rise. At this time, the side of transmission chain 6 closer to the connecting plate becomes longer, while the side closer to top plate 42 becomes shorter. Since both ends of transmission chain 6 are fixed, it drives top plate 42 to rise, which in turn drives bottom plate 22 to rise, thus changing the position of sheet metal 11. When cylinder retracts, top plate 42 descends until bottom plate 22 contacts middle plate 43.

[0056] In the feeding process, firstly, when feeding is required, the pulling plate 21 extends into the bottom of the feeding bin 1 to pull out the sheet metal 11. Then, the fixing device 3 fixes the sheet metal 11. The lifting drive component drives the base plate 22 to rise. Then, the robotic arm can grab the sheet metal 11. At the same time, inside the feeding bin 1, the receiving plate 13 moves downward as a whole. The pulling plate 21 continues to pull the next sheet metal 11, realizing the automatic feeding of the sheet metal 11. The structure is compact, the precision is high, the space occupied is small, and the feeding efficiency is high.

[0057] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
