Description

Technical Field

[0001] This invention relates to the field of building formwork processing technology, and in particular to an adaptive stacking and feeding device and control method for CNC machining of building formwork. Background Technology

[0002] In the field of automated formwork processing technology, with the rapid development of the construction industry, the requirements for formwork processing efficiency are increasing. As an indispensable and important component in construction, the processing quality and production efficiency of formwork directly affect the progress and cost of construction projects.

[0003] Currently, CNC machine tools are widely used in template processing, but there are still many problems in the template feeding process. In the existing technology, CNC machine tool template processing mainly relies on the robotic arm suction cup for single-sheet feeding. This feeding method is extremely inefficient, and due to the height difference between the stacking height of the standard template package and the height of the machine tool table, misalignment is prone to occur during feeding, making it difficult to meet production capacity requirements.

[0020] Step 2: Use the feeding plate to smoothly push the five templates on the top layer of the first lifting platform to the second lifting platform.

Subsequently, the drive mechanism of the second lifting platform will quickly and smoothly adjust the lifting according to the calculated parameters, automatically positioning itself to the receiving preparation position, ensuring that the height difference between its table and the top of the current template is just enough to meet the needs of receiving the next batch of five templates, thus preparing for the next receiving action and realizing a continuous and efficient template feeding process.

At the same time, the limiting component can prevent the template from being misaligned during the pushing process. Attached Figure Description

Detailed Implementation

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figures 1-2 This is the first embodiment of the present invention. This embodiment provides an adaptive stacking and feeding device for CNC machining of building templates, including a feeding component 2 and a limiting component 3. The feeding component 2 and the limiting component 3 can improve the feeding efficiency and at the same time prevent the template from being misaligned during the pushing process.

[0039] Main structure 1, including mounting base 11; and,

[0040] The feeding assembly 2 includes a first lifting platform 21 fixedly connected to one side of the top of the mounting base 11. Feeding rails 22 are provided on both sides of the first lifting platform 21. A feeding plate 23 is provided on the top of the feeding rails 22. A feeding block 24 is fixedly connected to the side of the feeding plate 23 away from the first lifting platform 21. A driving component 25 is provided on the side of the feeding block 24 away from the feeding plate 23. A second lifting platform 26 is provided on one side of the first lifting platform 21. The bottom of the second lifting platform 26 is fixedly connected to the mounting base 11. A feeding conveyor belt 27 is provided on the top of the second lifting platform 26. A CNC machine tool 28 is provided on one side of the second lifting platform 26. The bottom of the CNC machine tool 28 is fixedly connected to the mounting base 11.

[0041] The limiting component 3 includes a connecting plate 31 fixedly connected to one side of the surface of the second lifting platform 26. A folding guard 32 is fixedly connected to one side of the connecting plate 31. A connecting arm 33 is fixedly connected to the other side of the surface of the second lifting platform 26. A linkage component 34 is provided on one side of the connecting arm 33.

[0042] Mounting base 11 serves as the supporting foundation for the entire device, providing a stable mounting platform for other components. The first lifting platform 21 is used to support the template stack, working in conjunction with the second lifting platform 26 to handle templates of different heights. Through the cooperation of the feeding rail 22, feeding plate 23, feeding block 24, and driving component 25, the templates can be pushed from the first lifting platform 21 to the second lifting platform 26, achieving simultaneous feeding of multiple templates and greatly improving feeding efficiency. The second lifting platform 26 is responsible for receiving the templates and sending them to the processing position of the CNC machine tool 28 via the feeding conveyor 27, solving the height difference problem between the templates and the machine tool table. Through the coordinated work of the connecting plate 31, folding edge 32, connecting arm 33, and linkage component 34, the templates are limited and protected during the template conveying process, preventing them from tipping over or misaligning, ensuring the stability and accuracy of the feeding process. This effectively overcomes the problems of low single-sheet feeding efficiency and easy misalignment during feeding in the prior art of robotic arm suction cups.

[0043] It should be noted that the first lifting platform 21, the second lifting platform 26, and the folding guard 32 are existing technologies, which are clearly known to those skilled in the art and will not be described in detail here.

[0044] Example 2

[0045] Reference Figures 1-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0046] Specifically, the driving component 25 includes a U-shaped plate 25-1 disposed on both sides of the top of the mounting base 11. A motor is embedded in the inner cavity of the U-shaped plate 25-1. The output shaft of the motor passes through the U-shaped plate 25-1 and is fixedly connected to a first gear 25-2. A sprocket 25-3 meshes with the surface of the first gear 25-2. A second gear 25-4 meshes with one side of the sprocket 25-3. The second gear 25-4 is rotatably connected to the surface of the U-shaped plate 25-1. A push plate 25-5 is fixedly connected to the top of the sprocket 25-3. A limit part 25-6 is provided on the surface of the push plate 25-5.

[0047] By embedding a motor in the U-shaped plate 25-1 set on both sides of the top of the mounting base 11, and the first gear 25-2 connected to the motor output shaft meshing with the sprocket 25-3 and the second gear 25-4, the rotational motion of the motor can be converted into the linear motion of the push plate 25-5. The limiting part 25-6 set on the surface of the push plate 25-5 can limit and guide the movement of the push plate 25-5, ensuring its stability and accuracy, thereby providing power for the feeding plate 23 to push the template. Compared with the existing robotic arm suction cup feeding, this transmission method has stronger power and more stable transmission, which can realize the rapid pushing of multiple templates, effectively improve the feeding efficiency, and also reduce the failure rate caused by frequent operation.

[0048] Specifically, the top of the feeding rail 22 is provided with a through groove 25-7, the bottom of the feeding block 24 passes through the through groove 25-7 and is slidably connected to the through groove 25-7, and a first spring 25-8 is fixedly connected to one side of the inner cavity of the through groove 25-7, and one side of the first spring 25-8 is fixedly connected to the feeding block 24.

[0049] The feeding block 24 can slide within the through groove 25-7, thereby providing guidance and constraint for the movement of the feeding block 24. The first spring 25-8 plays a role in buffering and resetting during the movement of the feeding block 24. When the feeding block 24 pushes the template, the first spring 25-8 is compressed and stores elastic potential energy. After the push is completed, the first spring 25-8 releases the elastic potential energy, driving the feeding block 24 to reset, preparing for the next feeding, and ensuring the continuity and stability of the feeding process.

[0050] Specifically, both sides of the inner cavity of the through groove 25-7 are fixedly connected with a clamping plate 25-9, and both sides of the feeding block 24 are provided with a clamping groove 25-10.

[0051] By using the clamping plate 25-9 and the clamping slots 25-10 on both sides of the feeding block 24, an engaging structure is formed, which further limits the sliding of the feeding block 24 in the through slot 25-7, preventing the feeding block 24 from shifting laterally or detaching from the through slot 25-7 during movement, ensuring that the feeding block 24 moves stably along the predetermined trajectory, thereby ensuring that the feeding plate 23 can accurately push the template to the designated position.

[0052] Specifically, a groove 25-11 is provided on the side of the feeding block 24 away from the feeding plate 23. A second spring 25-12 is fixedly connected to the inner cavity of the groove 25-11. A slope block 25-13 is fixedly connected to the side of the second spring 25-12 away from the feeding plate 23. The slope block 25-13 passes through the groove 25-11 and is slidably connected to the groove 25-11. The feeding rail 22 is fixedly connected to one side of the top of the U-shaped plate 25-1. An abutment plate 25-14 is fixedly connected to the side of the feeding rail 22 away from the first lifting platform 21 and cooperates with the slope block 25-13.

[0053] During the feeding process, when the slope block 25-13 contacts the slope surface of the abutment plate 25-14, the slope block 25-13 is forced to slide into the slide groove 25-11 and compress the second spring 25-12; when the push plate 25-5 continues to move, after the slope block 25-13 loses the limit of the push plate 25-5, it resets under the action of the second spring 25-12 and the first spring 25-8, realizing the automatic reset of the feeding block 24, ensuring that the feeding mechanism can work in cycles without manual intervention, and improving the automation level and working efficiency of the feeding device.

[0054] It should be noted that there is a height difference between the push plate 25-5 and the abutment plate 25-14, and there will be no interference during the movement.

[0055] Specifically, the limiting part 25-6 includes a support rod 25-61 fixedly connected to the side of the push plate 25-5 away from the first lifting platform 21, and a support rail 25-62 fixedly connected to the side of the U-shaped plate 25-1 near the support rod 25-61, and cooperating with the support rod 25-61.

[0056] During the movement of the push plate 25-5, the support rod 25-61 slides along the support rail 25-62, which can effectively prevent the push plate 25-5 from shaking or deviating, ensuring that the push plate 25-5 can accurately drive the feeding block 24 and the feeding plate 23 to move, thereby ensuring the accuracy and stability of the template push and improving the reliability of the feeding device.

[0057] Specifically, a vertical plate 25-15 is fixedly connected to the side of the U-shaped plate 25-1 away from the support rail 25-62. A side plate 25-17 is provided on one side of the vertical plate 25-15. The bottom of the side plate 25-17 is fixedly connected to the mounting base 11. A vertical groove 25-16 is opened through the surface of the side plate 25-17 and cooperates with the vertical plate 25-15.

[0058] The vertical plate 25-15 and the vertical groove 25-16 can effectively enhance the stability of the U-shaped plate 25-1, prevent the U-shaped plate 25-1 from tilting or displacing when under force, and ensure that the drive component 25 can work normally and stably, thereby ensuring the reliable operation of the entire feeding device.

[0059] Specifically, the linkage component 34 includes a linkage rod 34-1 fixedly connected to the bottom of the feeding block 24. The bottom of the linkage rod 34-1 passes through the feeding rail 22 and the U-shaped plate 25-1, and is slidably connected to a linkage plate 34-2. The top of the linkage plate 34-2 is provided with a linkage groove 34-3, which cooperates with the linkage rod 34-1.

[0060] During the movement of the feeding block 24, the linkage rod 34-1 slides in the linkage groove 34-3, thereby driving the linkage plate 34-2 to move through the inclined setting of the linkage groove 34-3, realizing the linkage between the two. This linkage structure can transmit the movement of the feeding block 24 to the linkage plate 34-2, providing a power transmission path for the subsequent use of the side baffle 34-4 on the linkage plate 34-2 to limit the template. This allows the side baffle 34-4 to move synchronously with the feeding process, limit the template in time, prevent the template from being misaligned during the pushing process, and improve the quality of template feeding.

[0061] Specifically, a side baffle 34-4 is fixedly connected to the side of the linkage plate 34-2 near the first lifting platform 21, and a reset plate 34-5 is fixedly connected to the other side of the linkage plate 34-2. A reset groove 34-6 is opened at the bottom of the U-shaped plate 25-1. A third spring 34-7 is fixedly connected to the inner cavity of the reset groove 34-6. The side of the third spring 34-7 away from the first lifting platform 21 is fixedly connected to the reset plate 34-5.

[0062] The side baffle 34-4 is used to limit the two sides of the template. The reset plate 34-5, the reset groove 34-6 and the third spring 34-7 work together. When the side baffle 34-4 limits the template, the reset plate 34-5 slides in the reset groove 34-6 and compresses the third spring 34-7. After the template is pushed out, the third spring 34-7 releases its elastic potential energy to assist the reset plate 34-5 and the linkage plate 34-2 in resetting, so that the side baffle 34-4 moves away from the template and prepares for the next feeding.

[0063] Working principle: When the adaptive stacking and feeding device for CNC machining of building formwork is working, one hundred formwork sheets are first neatly stacked on the first lifting platform 21. The first lifting platform 21 is controlled to be adjusted to the lowest height. At the same time, the top position of the formwork is detected by the sensor, and the second lifting platform 26 is controlled to be adjusted to the position where the top of the formwork is reduced by five formwork sheets, so that the second lifting platform 26 is in the material receiving preparation state.

[0064] Subsequently, the motors inside the U-shaped plates 25-1 on both sides of the top of the mounting base 11 are started. The motor output shaft drives the first gear 25-2 to rotate. The first gear 25-2 drives the sprocket 25-3 and the second gear 25-4 to rotate through meshing, thereby causing the push plate 25-5, which is fixedly connected to the sprocket 25-3, to rotate. During the rotation of the push plate 25-5, it drives the slope block 25-13, the feeding block 24, and the feeding plate 23 in contact with it to move. The feeding block 24 slides in the through groove 25-7 at the top of the feeding rail 22. During this process, the first spring 25-8 is compressed. When the slope block 25-13 contacts the slope surface of the abutment plate 25-14 on the feeding rail 22, the slope block 25-13 is forced to slide into the groove 25-11 of the feeding block 24 and compress the second spring 25-12. Then the push plate 25-5 continues to move, and after the slope block 25-13 loses the limit of the push plate 25-5, it will be reset with the feeding block 24 and the feeding plate 23 under the action of the first spring 25-8. At the same time, the second spring 25-12 will drive the slope block 25-13 to reset, so that the next feeding can be carried out after the push plate 25-5 rotates one revolution.

[0065] During the feeding process of the feeding plate 23, the feeding block 24 drives the linkage rod 34-1 fixedly connected to its bottom to move. The linkage rod 34-1 slides in the linkage groove 34-3 at the top of the linkage plate 34-2, thereby driving the linkage plate 34-2 and the side baffle 34-4 to move. The side baffle 34-4 limits the two sides of the template to prevent the bottom template from being misaligned due to friction during the pushing process. The side baffle 34-4 is always located at the height position after the total height of the current template is reduced by five template thicknesses. At the same time, the lifting and lowering of the second lifting platform 26 drives the connecting plate 31 to lift and lower, so that the folding baffle 32 can extend and retract. During the template pushing process, the folding baffle 32 can adapt to the height of the template and is always located at the height position after the total height of the current template is reduced by five template thicknesses, thereby preventing the template from tipping over during feeding.

[0066] Example 3

[0067] Reference Figures 1-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0068] The control method for an adaptive stacking and feeding device for CNC machining of building formwork includes the following steps:

[0069] Step 1: Neatly stack one hundred templates on the first lifting platform 21, control the first lifting platform 21 to the lowest height, and at the same time, use the sensor to detect the top position of the templates and control the second lifting platform 26 to adjust to the position where the top of the templates is reduced by five templates, so that the second lifting platform 26 is in the material receiving preparation state, laying the foundation for subsequent material receiving actions.

[0070] Step 2: Using the feeding plate 23, the top five templates on the first lifting platform 21 are smoothly pushed to the second lifting platform 26. After the second lifting platform 26 receives the five templates, the control system automatically triggers, causing the second lifting platform 26 to be lowered to the height of the CNC machine tool 28, ensuring that the template height is adapted to the machine tool table surface, which is convenient for subsequent pushing.

[0071] Step 3: After the second lifting platform 26 descends to the height of the CNC machine tool 28, the feeding conveyor 27 is activated to push the five templates on the second lifting platform 26 to the machine tool table at a uniform speed. After the templates reach the machine tool table, the machine tool's own positioning system completes the template positioning. After each push of five templates to the machine tool table, the second lifting platform 26 will start the automatic lifting function according to the built-in preset program. The system will monitor the total height of the remaining templates on the first lifting platform 21 in real time, collect the top position data of the templates through sensors, and calculate the position parameters after reducing the current total template height by five template thicknesses based on the initial template height and the number of templates already pushed. Subsequently, the drive mechanism of the second lifting platform 26 will quickly and smoothly adjust the lifting according to the calculated parameters, automatically positioning itself to the receiving preparation position, ensuring that the height difference between its table and the top of the current template just meets the requirements for receiving the next batch of five templates, preparing for the next receiving action, and realizing a continuous and efficient template feeding process.

10. A control method for an adaptive stacking and feeding device for CNC machining of building formwork as described in any one of claims 1-9, characterized in that, Includes the following steps: Step 1: Place one hundred templates neatly on the first lifting platform (21), control the first lifting platform (21) to the lowest height, and at the same time, detect the top position of the templates through the sensor and control the second lifting platform (26) to adjust to the position where the top of the templates is reduced by five templates, so that the second lifting platform (26) is in the material receiving preparation state, laying the foundation for subsequent material receiving actions. Step 2: Using the feeding plate (23), the top five templates on the first lifting platform (21) are smoothly pushed to the second lifting platform (26). After the second lifting platform (26) receives the five templates, the control system automatically triggers, so that the second lifting platform (26) is lowered to the height of the CNC machine tool (28) to ensure that the template height is compatible with the machine tool table surface, which is convenient for subsequent pushing. Step 3: After the second lifting platform (26) is lowered to the height of the CNC machine tool (28), the feeding conveyor (27) is started to push the five templates on the second lifting platform (26) to the machine tool table at a uniform speed. After the templates reach the machine tool table, the positioning system of the machine tool itself completes the template positioning. After each push of five templates to the machine tool table, the second lifting platform (26) will start the automatic lifting function according to the built-in preset program. The system will monitor the total height of the remaining templates on the first lifting platform (21) in real time, collect the top position data of the templates through the sensor, and calculate the position parameters after reducing the current total height of the templates by the thickness of five templates by the initial template height and the number of templates pushed. Then, the drive mechanism of the second lifting platform (26) will quickly and smoothly adjust the lifting according to the calculated parameters, automatically position itself to the receiving preparation position, and ensure that the height difference between its table and the top of the current template just meets the requirements of receiving the next batch of five templates, so as to prepare for the next receiving action and realize a continuous and efficient template feeding process.
