Description

Technical Field

[0001] This invention belongs to the technical field of sheet material conveying equipment, specifically a feeding device suitable for the production and processing of antistatic sheet materials. Background Technology

[0002] Antistatic sheets, also known as ESD protection sheets, are a type of functional engineering material specifically designed to eliminate, reduce, or prevent the accumulation of static charge. They are not ordinary plastics or metals, but rather possess superior static dissipation properties through special processes. They typically exhibit excellent mechanical properties such as high strength, high wear resistance, chemical corrosion resistance, and impact resistance, ensuring a long service life in harsh industrial environments. In terms of appearance, they offer a wide range of choices, including opaque solid-color sheets as well as fully transparent or semi-transparent sheets, to meet the visibility requirements of different applications. They have become an indispensable basic protective material in modern electronics manufacturing, precision instruments, medical and chemical industries, and aerospace.

[0003] In existing technologies, the feeding of antistatic sheets mostly relies on manual handling to the conveyor belt. This not only involves cumbersome procedures and consumes a lot of manpower and time, significantly increasing the workload of operators, but also directly leads to low overall feeding efficiency. In addition, when the sheets are discharged, they are easily displaced on the surface of the conveyor belt due to the impact force of their own weight when they come into contact with the conveyor belt. If they are not adjusted in time, they will directly interfere with the accurate positioning of subsequent processing steps such as cutting and drilling, ultimately resulting in a significant decrease in the practicality of the device.

[0004] Therefore, we propose a feeding device suitable for the production and processing of antistatic sheets to solve the problems encountered above. Summary of the Invention

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

[0015] (1) Drive motor 1 drives drive rod 1, drive rod 1 drives rotating rod 1 to rotate, so that movable block 1 slides up and down along circular rod 1. With the elastic reset of spring, drive connecting block drives push block to reciprocate. The strip push plate on push block can automatically push the antistatic board to be fed from working plate 1 and working plate 2 to the transmission belt.

[0024] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0025] Example 1:

[0026] Please see Figure 1 - Figure 3As shown, a feeding device suitable for the production and processing of antistatic sheet materials includes two support frames 1. Two load-bearing frames 2 are fixedly connected to the upper surface of each support frame 1. A placement plate 3 is fixedly connected to the left side of the left support frame 1. A drive motor 4 is fixedly installed on the upper surface of the placement plate 3. A drive rod 5 is fixedly connected to the power output end of the drive motor 4. A rotating rod 6 is fixedly connected to the right side of the drive rod 5. A movable block 7 is fixedly connected to the right side of the rotating rod 6. A circular rod 8 is movably installed inside the movable block 7. A spring 9 is movably installed above the outer surface of the circular rod 8 and is located above the movable block 7. A connecting block 10 is fixedly connected to the upper surface of the circular rod 8.

[0027] A fixing ring 11 is fixedly connected to the lower surface of the connecting block 10. A rotating block 12 is movably arranged inside the fixing ring 11 via a rotating rod. A square rod 13 is fixedly connected to the upper surface of the rotating block 12. A push block 14 is fixedly connected to the upper surface of the square rod 13. Six soft pads 15 are fixedly connected to the upper surface of the push block 14. A strip push plate 16 is fixedly connected to the rear of the soft pads 15.

[0028] In the existing technology, the feeding process of antistatic sheets mostly relies on manual handling to the conveyor belt. This not only involves a complicated operation process, which consumes a lot of manpower and time, significantly increasing the workload of operators, but also directly leads to low overall feeding efficiency.

[0029] The antistatic sheet material to be transported is placed on the upper surfaces of work plate 25 and work plate 26. Drive motor 4 is started, and its rotation drives drive rod 5 to rotate. Rotating rod 6, fixedly connected to its right side, rotates synchronously. Movable block 7, fixedly connected to rotating rod 6, moves in a circular motion along with the rotation of rod 6. Because movable block 7 is fitted onto the outer surface of circular rod 8, it is limited by the circular rod 8, converting the circular motion into a sliding motion along the circular rod 8. During this sliding motion, when movable block 7 moves upward, it compresses the spring 9 above it, causing elastic deformation and generating a reverse force. When movable block 7 moves downward, the spring 9 releases its force, assisting in the resetting of movable block 7. In this process, spring 9 not only acts as a buffer but also prevents the movable block from moving downward. The hard collision between the moving block 7 and the connecting block 10 can also automatically adjust the sliding stroke of the moving block 7 according to the thickness of the antistatic board, so as to realize the adaptation and pushing of boards of different thicknesses and improve the versatility of the device. The upper surface of the circular rod 8 is fixedly connected to the connecting block 10. When the moving block 7 drives the circular rod 8 to move up and down, the connecting block 10 moves up and down synchronously. The fixed ring 11 fixed on the lower surface of the connecting block 10 is movably connected to the rotating block 12 through the rotating rod. Under the drive of the connecting block 10, the rotating block 12 can rotate around the rotating rod at a certain angle. At the same time, it can adjust its position in the up and down direction with the connecting block 10, so as to provide angle adaptation and position adjustment for the pushing action of the push block 14. The square rod 13 fixed on the upper surface of the rotating block 12 adjusts its position and angle synchronously with the movement of the rotating block 12, thereby driving the upper fixed push block 14 to move to the position that is in contact with the bottom or side of the antistatic board. During this process, the rotation of the rotating block 12 adjusts the angle of the push block 14, ensuring that the push block 14 and the contact surface of the board remain flat and in close contact, avoiding excessive local force that could damage the board. The six soft pads 15 fixed to the upper surface of the push block 14 first contact the antistatic board. The soft pads 15 are made of elastic material, effectively preventing hard friction between the push block 14 and the board surface, preventing scratches on the antistatic coating, and protecting the product quality of the board. Simultaneously, the strip push plate 16 fixed behind the soft pads 15 moves forward synchronously with the push block 14. The strip push plate 16 has a larger contact area with the board, allowing for more even application of pushing force, ensuring the board... The material remains stable during the feeding process without tilting or shifting. The square rod 17 connected to the right side of the rotating block 12 will drive the movable sleeve 18 to move on the circular rod 19. The movable circular sleeve 20 above the circular rod 19 will slide on the limiting rod 21. The limiting rod 21 is fixed by the fixing block 22 and the fixing block 23. The connecting plate 24 on the fixing block 23 assists in stabilizing the structure, ensuring that the movement of each component is smooth and the position is accurate during the feeding process, and avoiding the offset of the material. After one feeding is completed, the drive motor 4 drives each component to rotate in the opposite direction, and the movable block 7 returns to the initial position under the reset action of the spring 9.

[0030] Example 2:

[0031] Please refer to the following: Figure 4 - Figure 5 As shown, a working plate 25 is fixedly connected to the upper surface of the left supporting frame 2, and a working plate 26 is fixedly connected to the upper surface of the right supporting frame 2. The front of the connecting plate 24 is fixedly connected to the rear of the working plate 26, and the upper surface of the fixing block 22 is fixedly connected to the lower surface of the working plate 26. A limiting sleeve 27 is fixedly connected to the rear of the upper surfaces of the working plates 25 and 26, and a limiting plate 28 is fixedly connected to the front of the upper surfaces of the working plates 25 and 26. A transmission belt 29 is provided below the working plates 25 and 26, and a receiving plate 30 is fixedly connected to the left side of the transmission belt 29. The upper surface of the receiving plate 30 is fixed... A platform 31 is connected, and a second drive motor 32 is fixedly mounted on the upper surface of the platform 31. A second drive rod 33 is fixedly connected to the power output end of the second drive motor 32. A calibration component 34 is located on the right side of the second drive rod 33. The calibration component 34 includes a second rotating rod 35. A first lead screw 36 is fixedly connected to the right side of the second rotating rod 35. A first rotating shaft 37 is movably mounted on the right side of the first lead screw 36. Two load-bearing plates 38 are movably mounted on the right side of the first rotating shaft 37, located on the left and right sides of the calibration component 34 respectively. A threaded cylinder 39 is threadedly connected to the outer surface of the first lead screw 36. A receiving plate 30 is fixedly connected to the front of the threaded cylinder 39. A connecting post 41 is fixedly connected to the lower surface of the threaded cylinder 39. A calibration plate 42 is fixedly connected to the lower surface of the connecting post 41. A guide rail plate 43 is fixedly connected to the left side of the right-side load-bearing plate 38. A guide groove 44 is provided on the right side in front of the guide rail plate 43, and a guide block 40 is located inside the guide groove 44. A rotating shaft 45 is movably arranged in front of the left side of the load-bearing plate 38. A rotating rod 46 is fixedly and movably arranged on the left side of the rotating shaft 45. A lead screw 47 is fixedly connected to the left side of the rotating rod 46. A rotating shaft 48 is movably arranged on the left side of the lead screw 47, and the rotating shaft 48 is connected to the right side of the left-side load-bearing plate 38. 7 has a threaded cylinder 49 on its outer surface. A guide block 50 is fixedly connected to the rear of the threaded cylinder 49. A connecting post 51 is fixedly connected to the lower surface of the threaded cylinder 49. A calibration plate 52 is fixedly connected to the lower surface of the connecting post 51. A guide rail plate 53 is fixedly connected to the right side of the left load-bearing plate 38. A guide groove 54 is opened on the left side in front of the guide rail plate 53. The guide block 50 is located inside the guide groove 54. A gear 55 is fixedly connected to the middle position of the outer surface of the rotating rod 35. A gear 56 is meshed with the outer surface of the gear 55. The gear 56 is fixedly connected to the middle position of the outer surface of the rotating rod 46.

[0032] In the existing technology, when the sheet material is discharged, it is affected by the impact force of its own weight when it comes into contact with the conveyor belt. It is easy for the position to shift on the upper surface of the conveyor belt. If it is not adjusted in time, it will directly interfere with the accurate positioning of subsequent processing steps such as cutting and drilling, and ultimately lead to a significant decrease in the practicality of the device.

[0033] The drive motor 32, fixed to the support plate 30 and platform 31, is activated. Its power output drives the drive rod 33 to rotate, thereby driving the calibration assembly 34 to operate. The drive rod 33 drives the rotating rod 35 to rotate. The gear 55 on the rotating rod 35 meshes with the gear 56, causing the rotating rod 46 to rotate synchronously. The rotating rod 35 drives the lead screw 36 to rotate, and the threaded cylinder 39 moves along the lead screw 36. The guide block 40 in front of it slides in the guide groove 44 of the guide plate 43, ensuring the threaded cylinder... The first 39 moves smoothly, and then the first 41 drives the first calibration plate 42 to adjust its position laterally. At the same time, the third rotating rod 46 drives the second lead screw 47 to rotate, and the second threaded cylinder 49 moves along the second lead screw 47. The second guide block 50 at the rear slides in the second guide groove 54 of the second guide plate 53. The second calibration plate 52 is adjusted laterally through the second connecting rod 51. The first calibration plate 42 and the second calibration plate 52 work together to calibrate the position of the anti-static material on the working plate from both sides to ensure that the center of the material is aligned with the subsequent conveying path.

[0034] The specific working process of this invention is as follows:

[0035] When using this device, the operator places the antistatic sheet material to be fed onto the working plate 25 and the working plate 26. The material is initially aligned using the limiting sleeve 27 and the limiting plate 28, ensuring the edge of the material does not exceed the working plate area. The operator then starts drive motors 4 and 32. Drive motor 4 drives rotating rod 6 via drive rod 5. Movable block 7 slides up and down along circular rod 8, resetting with spring 9. This causes connecting block 10 and rotating block 12 to rotate together. The rotating block 12 rotates, pushing push block 14 via square rod 13. The strip push plate 16, cushioned by soft pad 15, smoothly pushes the antistatic sheet material from the working plate downwards. During the pushing process of the transmission belt 29, the movable sleeve 18 slides along the circular rod 29 and the moving circular sleeve 20 slides along the limiting rod 21 to ensure the smooth movement of the push block 14. Then, the drive motor 22 drives the rotating rod 25 to rotate through the drive rod 23. The gear 1 55 meshes with the gear 2 56, synchronously driving the lead screw 1 36 and the lead screw 2 47 to rotate. The threaded cylinder 1 39 moves along the lead screw 1 36, driving the calibration plate 1 42 to adjust left and right along the guide groove 1 44. The threaded cylinder 2 49 moves along the lead screw 2 47, driving the calibration plate 2 52 to adjust back and forth along the guide groove 2 54. The two-way cooperation calibrates the offset plate on the transmission belt 29 to the center position, which is convenient for later transportation.
