Description

Technical Field

[0001] This utility model belongs to the field of stacking and unloading technology, and in particular relates to an automatic positioning device for stacking and unloading on a material unloading line. Background Technology

[0002] In modern industrial production, the stacking and unloading of materials on the blanking line is an important step in the processing of metal sheets, plastic sheets and other materials. Traditional stacking and unloading devices mostly use manual positioning or simple mechanical positioning methods, which have problems such as low positioning accuracy, low efficiency and high labor intensity, making it difficult to meet the needs of high-precision and automated production.

[0003] Currently, although some automated positioning devices on the market have improved positioning accuracy to a certain extent, they still have the following technical defects: most devices adopt a fixed structure or a single drive method, which has poor versatility, relies on manual intervention to adjust the stacking position, and cannot be coordinated with other equipment on the production line. Utility Model Content

[0004] The technical problem this invention aims to solve is that most devices adopt a fixed structure or a single drive method, resulting in poor versatility, reliance on manual intervention to adjust the stacking position, and inability to coordinate with other equipment on the production line.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic positioning device for stacking and unloading materials on a material feeding line, comprising a base, a support column rotatably connected to the top of the base, a support plate fixedly connected to the upper end of the support column, a fixing frame fixedly connected to the top of the support plate, and a vertically movable feeding plate provided on one side of the fixing frame, and further comprising...

[0006] An adjustment assembly, mounted on a fixed frame, includes a servo motor fixedly mounted on the top of the fixed frame. The output end of the servo motor is fixedly connected to a threaded column, and its lower end is rotatably connected to the top of a support plate. An adjustment block is threadedly connected to the threaded column, and the feeding plate is fixedly connected to the adjustment block.

[0007] The positioning and feeding assembly is located on the feeding plate and includes a vision recognition device fixedly installed at the end of the feeding plate. Laser range sensors symmetrically distributed relative to the vision recognition device are fixedly installed at the end of the feeding plate. A vertical plate is fixedly connected to the top of the feeding plate. A horizontal electric push rod is fixedly installed on the vertical plate. A push plate is fixedly connected to the free end of the electric push rod.

[0008] Furthermore, a stepper motor is fixedly installed on the top of the base, a worm gear is fixedly connected to the output end of the stepper motor, and a worm wheel that meshes with the worm gear is fixedly connected to the support column.

[0009] Furthermore, a limiting hole is provided on the fixing frame, and a limiting block is fixedly connected to the outer wall of the adjusting block, with the limiting block moving through the limiting hole.

[0010] Furthermore, a limiting plate is fixedly connected to the top of the feeding plate, and it is symmetrically distributed in front and behind relative to the electric push rod. The feeding plate and the limiting plate are slidably connected.

[0011] Furthermore, a limiting ring is fixedly connected to the top of the base, and symmetrically distributed support blocks are fixedly connected to the bottom of the support plate. The support blocks and the limiting ring are slidably connected.

[0012] Furthermore, a controller is fixedly installed on the top of the support plate, and the vision recognition device, laser rangefinder, stepper motor, servo motor and electric push rod are all electrically connected to the controller.

[0013] Furthermore, guide rods symmetrically distributed front and rear are fixedly connected between the fixed frame and the support plate, and the feeding plate passes through the guide rods and is slidably connected to them.

[0014] The beneficial effects of this utility model after adopting the above structure are as follows:

[0015] (1) When the material is placed on the feeding plate, the vision recognition device acquires the image of the material, and at the same time the laser range sensor accurately measures the material position parameters. These data are transmitted to the controller for processing and analysis in real time.

[0016] (2) The controller issues instructions according to the preset program, the servo motor starts to run, and drives the threaded column to rotate. At this time, the adjusting block achieves stable vertical displacement under the dual guidance of the limiting hole and the limiting block; at the same time, the stepper motor starts and drives the material to rotate and adjust through the precision meshing of the worm and the worm wheel.

[0017] (3) During the entire adjustment process, the support block rotates stably along the limit ring to ensure that the support plate always maintains good stability. When the system determines that the material has reached the preset target position, the controller issues the final command, and the electric push rod extends to push the push plate to complete the horizontal pushing action and accurately stack the material to the designated work station.

[0024] like Figure 1-2 As shown, an automatic positioning device for stacking and unloading materials on a material unloading line includes a base 1, a support column 2 rotatably connected to the top of the base 1, a support plate 22 fixedly connected to the upper end of the support column 2, a fixed frame 3 fixedly connected to the top of the support plate 22, a vertically movable feeding plate 4 provided on one side of the fixed frame 3, and also includes an adjustment component and a positioning feeding component. The adjustment component is located on the fixed frame 3, and the positioning feeding component is located on the feeding plate 4.

[0025] like Figure 1-4As shown, to facilitate the adjustment of the material position, the adjustment assembly includes a servo motor 5 fixedly mounted on the top of the fixed frame 3. A threaded column 6 is fixedly connected to the output end of the servo motor 5, and its lower end is rotatably connected to the top of the support plate 22. An adjustment block 7 is threadedly connected to the threaded column 6. The feeding plate 4 is fixedly connected to the adjustment block 7. A limit hole 16 is provided on the fixed frame 3. A limit block 17 is fixedly connected to the outer wall of the adjustment block 7, and the limit block 17 moves through the limit hole 16. A stepper motor 13 is fixedly mounted on the top of the base 1. A worm gear 14 is fixedly connected to the output end of the stepper motor 13. A worm gear 14 is fixedly connected to the support column 2. The worm gear 15 meshes with the rod 14. The top of the base 1 is fixedly connected to the limit ring 19. The bottom of the support plate 22 is fixedly connected to the left and right symmetrically distributed support blocks 20. The support blocks 20 and the limit ring 19 are slidably connected. The servo motor 5 starts to run, driving the threaded column 6 to rotate. At this time, the adjusting block 7 achieves stable vertical displacement under the dual guidance of the limit hole 16 and the limit block 17. At the same time, the stepper motor 13 starts and drives the material to rotate and adjust through the precise meshing of the worm gear 14 and the worm wheel 15. During the adjustment process, the support block 20 rotates stably along the limit ring 19 to ensure that the support plate 22 always maintains good stability.

[0026] like Figure 1-4 As shown, to facilitate material unloading and stacking operations, the positioning and unloading assembly includes a vision recognition device 8 fixedly installed at the end of the unloading plate 4. Laser rangefinders 9 are symmetrically distributed relative to the vision recognition device 8 and fixedly installed at the end of the unloading plate 4. A vertical plate 10 is fixedly connected to the top of the unloading plate 4. A horizontal electric push rod 11 is fixedly installed on the vertical plate 10. A pusher plate 12 is fixedly connected to the free end of the electric push rod 11. A limit plate 18 is fixedly connected to the top of the unloading plate 4 and is symmetrically distributed front and back relative to the electric push rod 11. The pusher plate 12 is slidably connected to the limit plate 18. When the system determines that the material has reached the preset target position, the controller 21 issues the final command, and the electric push rod 11 extends to push the pusher plate to complete the lateral pushing action, accurately stacking the material to the designated work station.

[0027] The top of the support plate 22 is fixedly equipped with a controller 21. The vision recognition device 8, the laser rangefinder 9, the stepper motor 13, the servo motor 5 and the electric push rod 11 are all electrically connected to the controller 21. The fixed frame 3 and the support plate 22 are fixedly connected with guide rods 23 that are symmetrically distributed front and back. The feeding plate 4 passes through the guide rods 23 and is slidably connected to them. When the feeding plate 4 moves vertically, the guide rods 23 can increase its stability.

[0028] In practical use, the vision recognition device 8 consists of a high-definition industrial camera and an image acquisition card, which is existing technology. It processes digital images through image recognition algorithms to identify the shape, size, and position of the material in the image, further assisting in determining the precise position of the material. In conjunction with the laser rangefinder 9, it determines the approximate position of the material in three-dimensional space. After the material is placed on the feeding plate 4, according to the signal transmitted to the controller 21 by the vision recognition device 8 in conjunction with the laser rangefinder 9, the servo motor 5 drives the threaded column 6 to rotate. The adjusting block 7 moves vertically under the limiting guidance of the limiting hole 16 and the limiting block 17. The stepper motor 13 runs, and the meshing transmission of the worm gear 14 and the worm wheel 15 can rotate the material. During the process, the support block 20 rotates on the limiting ring 19, which increases the stability of the support plate. After the material is moved to the appropriate position, the electric push rod 11 is extended to make the pusher plate move laterally, thereby pushing the material down and stacking it in the corresponding position.
