An adaptive positioning mechanism and positioning method for multi-layer tooling containers

Abstract

An adaptive positioning mechanism and method for multi-layer tooling containers includes a support body disposed at the bottom of the multi-layer tooling container and a lifting tray attached to the support body and fixedly connected to the bottom of the tooling container. The support body is equipped with a lifting component and a power component. The power component has a power-driven slider, which is convexly connected to a movable part of the lifting component. The movable part, pushed by the slider, causes the lifting component to push the lifting tray up and down, thereby adjusting the positioning of the multi-layer tooling container. This invention effectively solves the problem of inconsistent layer heights in the tooling container, leading to non-standardized and uniform positioning heights, by adaptively adjusting the height of the multi-layer tooling container through the power component and lifting mechanism. It also solves the problem of deviations in the necessary positioning parameters of the tooling container caused by other factors (such as tire wear).

Description

Technical Field

[0001] This invention relates to the field of positioning technology for multi-layer tooling containers in cross-regional material transfer production, and in particular to an adaptive positioning mechanism and positioning method for multi-layer tooling containers. Background Technology

[0002] Currently, in the manufacturing industry, tooling containers are widely used to deliver semi-finished products and buffer materials. These containers facilitate cross-regional material transfer for production. Both upstream and downstream processes involve automated loading and unloading of materials using these containers. To ensure this automated loading and unloading, the uniformity of the tooling containers is crucial, particularly in terms of consistent layer height and reference height. However, in actual production, significant errors occur during the manufacturing, use, and transportation of tooling containers, leading to substantial inaccuracies in their positioning within automated workstations. For example, manufacturing errors can result in inconsistent layer heights, affecting positioning accuracy; wear and deformation during transportation can cause deviations between the actual and designed positions of different locations within the container, resulting in inconsistent reference heights and ultimately, inaccurate material positioning on the containers. Summary of the Invention

[0003] To address the issue of inconsistent layer heights in tooling containers leading to non-standardized precise positioning heights, this invention provides an adaptive positioning mechanism and method for multi-layer tooling containers. The adaptive positioning mechanism adjusts the tooling container to the precise height required for gripping by automated equipment, enabling the automated equipment to accurately grip materials, improving the error tolerance of the automated equipment, and meeting the precise positioning requirements of different tooling containers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an adaptive positioning mechanism for a multi-layer tooling container, comprising a support body disposed at the bottom of the multi-layer tooling container and a lifting tray attached to the support body and fixedly connected to the bottom of the tooling container. The support body is provided with a lifting component and a power component. The power component has a slider driven by power. The slider is convexly connected to a movable part of the lifting component. The movable part is pushed by the slider, causing the lifting component to push the lifting tray up and down to adjust the positioning of the multi-layer tooling container.

[0005] Preferably, the lifting component has an upper fixed part and an upper movable part connected to the lifting tray, and a lower fixed part and a lower movable part connected to the support body. The upper fixed part and the lower movable part, as well as the upper movable part and the lower fixed part, are respectively hinged by scissor arms, and the two scissor arms on the same side are arranged to cross each other.

[0006] Preferably, linear guide rails are provided on both sides of the support body and the lifting tray, and the lower movable part and the upper movable part are respectively slidably assembled on the linear guide rails. A push shaft is provided between the lower movable parts, and the push shaft is fixedly connected to the slider of the power component and drives the transmission.

[0007] Preferably, buffer blocks are provided at both ends of the linear guide rail.

[0008] Preferably, the power component includes a servo motor, a ball screw disposed at the output end of the servo motor, and a slider mounted on the ball screw. The ball screw is driven to rotate by the servo motor so that the slider makes linear reciprocating motion on the ball screw. The slider is connected to a push shaft of the lifting component to make the movable part move closer to or away from the fixed part.

[0009] Preferably, the support body is further provided with a fixing plate and a fixing beam overlapping on both sides of the support body, the servo motor is mounted on the fixing plate, one end of the ball screw is connected to the output end of the servo motor for transmission, and the other end is connected to the fixing beam through a bearing seat, and the slider is fixedly connected to and driven by the push shaft between the lower movable part of the lifting component.

[0010] Preferably, upright supports are also provided on both sides of the support body, and the height of the upright supports is the same as the height of the lifting component when it is in its lowest state.

[0011] On the other hand, the present invention adopts the following technical solution: a production equipment, including an adaptive positioning mechanism for multi-layer tooling containers as described above.

[0012] On the other hand, the present invention adopts the following technical solution: an adaptive positioning method for multi-layer tooling containers, comprising the following steps:

[0013] The detection module starts detecting from the first layer of the multi-layer tooling container. After the sensor receives the signal, it indicates that the material is in place. Each layer of the multi-layer tooling container is equipped with a corresponding sensor to determine the standard position of each layer.

[0014] The lifting component is driven by the power component to raise the multi-layer tooling container by half the height of the first layer, and then it begins to descend until it stops when the sensor receives a signal. This position is the material clamping position for that layer.

[0015] Preferably, the method further includes the following steps:

[0016] The system receives signal feedback from the detection module and calculates the input signal of the servo motor through the control module. The input signal includes a speed signal and a rotation angle signal.

[0017] The servo motor of the power unit is started according to the input signal and transmitted to the ball screw through the coupling, which in turn causes the slider on the ball screw to perform translational motion, driving the push shaft and the lower movable part to move on the linear guide rail;

[0018] The movement of the movable part causes the scissor arm, which is hinged to the fixed part, to swing, driving the multi-layer tooling container fixed on the lifting component to move up and down to the set height, completing the precise positioning so that the automated loading and unloading equipment can proceed to the next step.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention adaptively adjusts the height of multi-layer tooling containers through a power component and a lifting mechanism. Sensors in the detection module acquire the layer height positions of the multi-layer tooling containers in real time. Using a low-cost method, it enables automatic and precise positioning of the tooling containers, facilitating accurate material placement. It effectively solves the problem of inconsistent layer heights in tooling containers, which leads to non-standardized positioning heights. It also addresses the issue of deviations in necessary positioning parameters caused by other factors (such as tire wear).

[0021] This invention, through sensor control and mechanical lifting, can adapt to materials of different sizes, models, and weights. By controlling and adjusting the tooling container to the precise height required for automated equipment gripping, it enables the automated equipment to accurately grasp materials, improving the error tolerance of the gripping process and meeting the precise positioning requirements of different tooling containers. Real-time feedback from sensors ensures the adaptive adjustment of the tooling container's position, ultimately achieving precise positioning. Attached Figure Description

[0032] like Figure 1-3 As shown, an adaptive positioning mechanism for a multi-layer tooling container includes a support body 200 disposed at the bottom of the multi-layer tooling container 100 and a lifting tray 300 mounted on the support body 200 and fixedly connected to the bottom of the tooling container 100. The support body 200 is provided with a lifting component 400 and a power component 500. The power component 500 has a power-driven slider 510. The slider 510 is convexly connected to a movable part of the lifting component 400. The movable part is pushed by the slider 510, causing the lifting component 400 to push the lifting tray 300 up and down to adjust the positioning of the multi-layer tooling container 100.

[0033] The lifting component 400 has an upper fixed part 410 and an upper movable part 411 connected to the lifting tray 300, and a lower fixed part 420 and a lower movable part 421 connected to the support body 200. The upper fixed part 410 and the lower movable part 421, and the upper movable part 411 and the lower fixed part 420 are respectively hinged by scissor arms 430, and the two scissor arms on the same side are arranged to cross each other.

[0034] Linear guide rails 440 are provided on both sides of the support body 200 and the lifting tray 300. The lower movable part 421 and the upper movable part 411 are slidably mounted on the linear guide rails 440 respectively. Specifically, the front and rear supports of the support body 200 are provided with lower linear guide rails. The lower linear guide rails are fixed to the left or right. The other left or right side is used to set the lower fixed part 410. The lower movable part 411 is slidably mounted on the lower linear guide rail. The bottom of the front and rear supports of the lifting tray 300 is provided with upper linear guide rails. The upper linear guide rails are fixed to the left or right side, aligned with the lower linear guide rails. The other left or right side is provided with an upper fixed part 420, aligned with the lower fixed part 410. The upper movable part 421 is slidably mounted on the upper linear guide rail. Buffer blocks are provided at both ends of the linear guide rails for protection.

[0035] A push shaft 450 connects the lower movable parts 411 on both the front and rear sides. The push shaft 450 is fixedly connected to and drives the slider 510 of the power component. Connecting shafts connect the upper fixed parts, lower fixed parts, and upper movable parts on both sides to enable synchronous lifting and / or translation of the fixed and movable parts. Scissor arms are connected by scissor shafts at their intersections to ensure synchronicity of the scissor arms on both sides, thereby improving the lifting stability of the lifting mechanism.

[0036] The power unit 500 includes a servo motor 520, a ball screw 530 disposed at the output end of the servo motor 520, and a slider 510 mounted on the ball screw 530. The ball screw 530 is driven to rotate by the servo motor 520 so that the slider 510 makes linear reciprocating motion on the ball screw 530. The slider 510 is connected to a push shaft 450 of the lifting unit 400 so that the movable part moves closer to or away from the fixed part.

[0037] The support body 200 is also provided with a fixing plate 210 and a fixing beam 220 overlapping on both sides of the support body 200. The servo motor 520 is mounted on the fixing plate 210. One end of the ball screw 530 is connected to the output end of the servo motor 520 for transmission, and the other end is connected to the fixing beam 220 through the bearing seat 531. The slider 510 is fixedly connected to and driven by the push shaft 450 between the slider and the lower movable part 411 of the lifting component 400.

[0038] The support body 200 is also provided with upright supports 230 on both sides. The height of the upright supports 230 is the same as that of the lifting component when it is in the lowest state. When the lifting component is lowered to the lowest state, the top of the upright supports is used to support the two sides of the lifting tray.

[0039] In this embodiment, power is output from a power component to drive the rotation of the ball screw 530. This causes the slider 510, which is mounted on the ball screw 530, to convert the rotational motion into linear motion via a thread. The slider moves linearly on the ball screw 530 and drives the push shaft 450. The lower movable parts 411 on both sides of the push shaft 450 move on linear guide rails. When the lower movable parts approach the lower fixed part, the two scissor arms on the same side rotate toward an upright position around the scissor shaft. As a result, the upper fixed part and the upper movable part perform an upward lifting motion, thereby raising the lifting tray. Conversely, when the lower movable parts move away from the lower fixed part, the lifting tray lowers.

[0040] This implementation case controls the output of the servo motor in the power unit to adjust the tooling container to the precise height required for gripping by the automated equipment, enabling the automated equipment to accurately grip the material, improving the error tolerance of the automated equipment, and meeting the precise positioning requirements of different tooling containers.

[0041] On the other hand, this embodiment also has another technical solution: an adaptive positioning method for multi-layer tooling containers. The detection module 600 detects the height of each layer of each tooling container through the sensor 610 and transmits the real-time position to the control module. The control module mainly controls the adaptive positioning mechanism to correct the height of the tooling containers through the collected sensor signals, specifically including the following steps:

[0042] The detection module 600 starts detecting from the first layer of the multi-layer tooling container 100. After the sensor 610 receives the signal, it indicates that the material is in place. Each layer of the multi-layer tooling container 100 is equipped with a corresponding sensor 610 to determine the standard position of each layer. The sensor type described in this embodiment can be a laser sensor, a photoelectric sensor, or a distance sensor, and the specific selection depends on the required detection accuracy, detection distance, and cost.

[0043] The lifting component 400 is driven by the power component 500 to raise the multi-layer tooling container 100 by half the height of the moving layer (the sensor has no signal at this position where the layer height is half raised), and then it begins to descend until it stops when the sensor receives a signal. This position is the material clamping position for that layer. Specifically, the signal feedback from the detection module is received, and the input signal of the servo motor is calculated by the control module. The input signal includes a speed signal and a rotation angle signal.

[0044] The servo motor of the power unit is started according to the input signal and transmitted to the ball screw through the coupling, which in turn causes the slider on the ball screw to perform translational motion, driving the push shaft and the lower movable part to move on the linear guide rail;

[0045] The movement of the movable part causes the scissor arm, which is hinged to the fixed part, to swing, driving the multi-layer tooling container fixed on the lifting component to move up and down to the set height, completing the precise positioning so that the automated loading and unloading equipment can proceed to the next step.

[0046] This implementation case uses a detection module and sensors distributed at different locations to detect the position of the tooling container. An adaptive positioning mechanism, employing power and lifting components, achieves lifting functionality. Real-time feedback from the sensors ensures the tooling container's position is adaptively adjusted, ultimately achieving precise positioning. This effectively solves the problem of inconsistent tooling container heights leading to non-standardized positioning heights, and addresses the issue of deviations in necessary positioning parameters caused by other factors (such as tire wear). It utilizes low-cost sensor control combined with mechanical lifting components to achieve adaptive and precise positioning of the tooling container.

[0047] On the other hand, this embodiment also provides another technical solution: a production equipment, including an adaptive positioning mechanism for multi-layer tooling containers as described above.

[0048] The above disclosures are merely one or more preferred embodiments of the present invention, used to help understand the inventive concept of the technical solution, and are not intended to limit the present invention in any other way. Any other equivalent or conventional substitution schemes made by those skilled in the art based on the features defined by the present invention shall still fall within the scope of the present invention.
