Description

Technical Field

[0001] This invention relates to the field of loading station technology; for measuring contours or curvature; specifically, to a product roundness detection device and method in a loading station of an FMS automated line. Background Technology

[0002] A Flexible Manufacturing System (FMS) is a highly automated manufacturing system that can flexibly adapt to the production needs of different products. An open, square loading station is used in the FMS to place pallets and workpieces, assisting stacking robots or articulated robots in loading and unloading workpieces. This allows for more precise, safer, and more convenient robot positioning during automated operations. The loading platform can rotate automatically 360 degrees, and its open design facilitates the hoisting of tooling and workpieces. The manual side uses a manually sliding double-door design, which is convenient and aesthetically pleasing. Existing roundness detection devices are fixed to the loading station, and the vibration of the loading station can cause the roundness detection device to vibrate, thus affecting the accuracy of the roundness detection. Patent CN206838794U discloses a device for detecting the roundness of the inner hole of an alloy wire drawing die. The device includes a fixed plate with a first through hole at its center. Three grooves are formed on the upper end of the fixed plate, each with a sliding groove on its inner wall. Limiting devices are installed in each of the three grooves. A connecting rod is mounted on the lower end of the fixed plate, and a vibration damping device is installed on the lower end of the connecting rod. A rotating device is installed within the vibration damping device. The connection between the fixed plate and the vibration damping device is stable. Sliding feet are installed in the sliding grooves on both sides of a slider, allowing the slider to slide within the grooves. A spring is mounted on the slider, with the other end attached to one end of a groove. A limiting plate is mounted on the upper end of the slider. The spring force allows the wire drawing die to be fixed on the upper end of the fixed plate. However, this device cannot be applied to the roundness detection of products in the loading station of an FMS automated production line. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a product roundness detection device for the loading station in an FMS automated production line. This device has a compact and reasonable structure and is easy to operate. The product is placed in the loading station body, the first and second screws are loosened, and the first and second rotating rods are rotated to bring the dial indicator's measuring port into contact with the product. The first and second screws are then tightened to fix the dial indicator. The rotating component of the loading station body drives the product to rotate, thereby measuring the product's roundness using the dial indicator. The support component does not contact the loading station body, minimizing the impact of vibrations from the loading station body on the support component. Furthermore, the support component is equipped with shock-absorbing pads and blocks, further reducing the impact of vibrations on the dial indicator and making the dial indicator's measurement more accurate.

[0004] To achieve the above objectives, the technical solution of the present invention is to design a product roundness detection device for a loading station in an FMS automated production line, comprising a loading station body;

[0005] The testing mechanism includes a support component, a testing component, and a positional adjustment component for the testing component;

[0006] The support assembly includes a bracket with two vertical columns. The bracket is located outside the loading station body and is spaced from the outer wall of the loading station body. The detection assembly includes a dial indicator for roundness detection. Because the detection assembly is mounted on the position changing component, which in turn is mounted on the support assembly, and the loading station body has openings for the detection assembly and / or the position changing component to pass through, and because the bracket of the support assembly is spaced from the outer wall of the loading station body, vibrations of the loading station body cannot affect the detection mechanism.

[0007] A further technical solution is that the position changing component is a rotating assembly, a copper sheet, or an aluminum sheet.

[0008] A further technical solution is that a first connecting plate is provided at the bottom of the support, a plurality of shock-absorbing blocks are provided at the bottom of the first connecting plate, the same shock-absorbing pad is provided at the bottom of the plurality of shock-absorbing blocks, a second connecting plate is provided at the bottom of the shock-absorbing pad, and the second connecting plate is set on the ground; the support does not contact the main body of the loading station.

[0009] The support plate is installed on the bracket. The support plate passes through the main body of the loading station and one end of the support plate is set inside the main body of the loading station. The support plate does not contact the main body of the loading station.

[0010] The rotating assembly and the detection assembly are located in the main body of the loading station. The rotating assembly is connected to the support plate, and the detection assembly is located on the rotating assembly.

[0011] A further technical solution is that the rotating assembly includes a first rotating rod, one end of which is provided with a first sleeve, and the other end of which is provided with a second sleeve. The support plate is provided with a fixed shaft inside the loading station body, and the first sleeve is rotatably mounted on the fixed shaft.

[0012] A further technical solution is that the rotating assembly further includes a second rotating rod, one end of which is provided with a rotating shaft, and the second sleeve is rotatably mounted on the rotating shaft.

[0013] A further technical solution is that a first screw is provided on the first sleeve, and a second screw is provided on the second sleeve.

[0014] A further technical solution is that the first sleeve is connected to the fixed shaft via a bearing; the second sleeve is connected to the rotating shaft via a bearing.

[0015] A further technical solution is that the detection component includes a base, which is mounted on a second rotating rod. A light rod is mounted on the base, and a self-locking slider is mounted on the light rod. A dial indicator is mounted on the slider.

[0016] A further technical solution is that the dial indicator is mounted on the slider via a rotating arm, and the rotating arm is self-locking.

[0017] The present invention also provides a technical solution for detecting the roundness of products in the loading station of an FMS automatic line. The method uses the product roundness detection device in the loading station of the FMS automatic line. The product is placed in the main body of the loading station, the first screw and the second screw are loosened, the first rotating rod and the second rotating rod are rotated so that the dial indicator measuring port contacts the product, the first screw and the second screw are tightened to fix the dial indicator, and the rotating component of the loading station main body drives the product to rotate, thereby measuring the roundness of the product by the dial indicator.

[0018] Alternatively, the detection component can be mounted on a copper or aluminum sheet; the product is placed in the loading station body, and the copper or aluminum sheet is rotated so that the dial indicator measuring port contacts the product. The rotating component of the loading station body drives the product to rotate, and then the roundness of the product is measured by the dial indicator.

[0019] The loading station has an opening larger than the detection mechanism; a vertical column is rotatably mounted via a pivot fixed to the ground; a position changing component is rotatably mounted relative to another vertical column; the position changing component is a rotating assembly, a copper plate, or an aluminum plate; the rotating assembly is a straight rod; a dial indicator is fixedly mounted on the straight rod with its measuring port facing the product to be tested.

[0020] A rubber sleeve is fixedly fitted on the pivot corresponding to the vertical column, and the vertical column rotates and is fitted on the rubber sleeve; another pivot is fixedly installed on the vertical column corresponding to the straight rod, and a rubber sleeve is also fixedly fitted on the pivot; the straight rod has an opening that matches the pivot, and the opening is fitted on the rubber sleeve.

[0021] An opening is provided on the vertical column to match the rotating shaft fixed to the ground; this provides some resistance when rotating, and the position remains unchanged after rotating to a certain position. Unless subjected to a large torque, it is difficult to change the rotation angle, and the desired position can be reached after rotation (the outer diameter of the rotating shaft with the rubber sleeve is slightly larger than the inner diameter of the opening).

[0022] The pivot corresponding to the vertical column is a stepped pivot, with the lower half being a large pivot and the upper half being a small pivot. A frustum-shaped rubber sleeve is fixedly fitted on the large pivot, and an opening is provided on the vertical column. The maximum size of the entire structure consisting of the large pivot and the rubber sleeve is adapted to the opening. A second pivot is fixedly installed on the vertical column corresponding to the straight rod. The second pivot is also a stepped pivot, with the lower half being a large pivot and the upper half being a small pivot. A frustum-shaped rubber sleeve is fixedly fitted on the large pivot, and a second opening is provided on the straight rod. The maximum size of the entire structure consisting of the large pivot and the rubber sleeve of the second pivot is adapted to the second opening.

[0023] A limiting rod is slidably installed on the inner side wall of the loading station body near the straight rod. The end of the straight rod that is fixedly connected to the dial indicator is also fixedly connected to a connecting folding rod. An elastic ring is fixedly connected to the end of the limiting rod away from the side wall of the loading station body. The elastic ring matches the connecting folding rod for being sleeved on the connecting folding rod.

[0024] The end of the straight rod that is fixedly connected to the dial indicator is also fixedly connected to a connecting folding rod; a photoelectric sensor is installed inside the main body of the loading station. The transmitting end of the photoelectric sensor is fixedly connected to the inner side wall of the main body of the loading station near the support, and the receiving end of the photoelectric sensor is fixedly connected to the connecting folding rod; the photoelectric sensor is connected to the controller signal, and the controller is connected to the buzzer signal.

[0025] The advantages and beneficial effects of this invention are as follows: It has a compact and reasonable structure, and is easy to operate. The product is placed in the loading station body, the first and second screws are loosened, and the first and second rotating rods are rotated to bring the dial indicator's measuring port into contact with the product. The first and second screws are then tightened to fix the dial indicator. The rotating component of the loading station body drives the product to rotate, thereby measuring the roundness of the product through the dial indicator. The support component does not contact the loading station body, minimizing the impact of vibrations on the support component. Furthermore, the support component is equipped with shock-absorbing pads and blocks, which further reduce the impact of vibrations on the dial indicator, making the dial indicator's measurement more accurate.

[0026] Since the detection component is mounted on the position changer, which in turn is mounted on the support component, and the loading station body has an opening for the detection component and / or position changer to pass through, and the support component's bracket has a gap with the outer wall of the loading station body, the vibration of the loading station body cannot affect the detection mechanism.

[0027] The position-changing component is bendable and can be shaped after bending. Compared to the previous technical solution, it is more efficient and simpler to operate, eliminating the need for tightening / loosening screws and rotating the rotating rod, while maintaining almost no decrease in accuracy. The only drawback is the slightly higher frequency of replacing the copper or aluminum plates. Moreover, this method has the same wide applicability as the previous technical solution, as it can be bent to different degrees according to the product size in the loading station to achieve contact between the dial indicator measuring port and the product.

Detailed Implementation

[0049] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0050] Example 1: As Figures 1 to 6 As shown, the present invention is a product roundness detection device for loading station in FMS automatic line, including detection mechanism 2. Detection mechanism 2 includes support component 201, detection component 203 and position changing component of detection component. The position changing component is a rotation component 202. Support component 201 is disposed outside the loading station body 1 and does not contact the loading station body 1.

[0051] The support assembly 201 includes a bracket 2011. A first connecting plate 2012 is provided at the bottom of the bracket 2011. Multiple shock-absorbing blocks 2015 are provided at the bottom of the first connecting plate 2012. The same shock-absorbing pad 2014 is provided at the bottom of the multiple shock-absorbing blocks 2015. A second connecting plate 2013 is provided at the bottom of the shock-absorbing pad 2014. The second connecting plate 2013 is fixed to the ground. The bracket 2011 is located outside the loading station body 1 and does not contact the loading station body 1.

[0052] A support plate 2016 is provided on the top of the bracket 2011. The support plate 2016 passes through the loading station body 1. One end of the support plate 2016 is located inside the loading station body 1 and does not contact the loading station body 1.

[0053] In one embodiment, the support plate 2016 is provided with a protective cover inside the loading station body 1, or multiple protective covers may be provided.

[0054] The rotating component 202 and the detection component 203 are installed in the main body 1 of the loading station. The rotating component 202 is connected to the support plate 2016, and the detection component 203 is installed on the rotating component 202.

[0055] The rotating assembly 202 includes a fixed shaft 2021, a first rotating rod 2022, and a second rotating rod 2027. The fixed shaft 2021 is mounted on the support plate 2016. One end of the first rotating rod 2022 is provided with a first sleeve 2023, and the other end of the first rotating rod 2022 is provided with a second sleeve 2025. The first sleeve 2023 is rotatably mounted on the fixed shaft 2021, and a first screw 2024 is rotatably mounted on the first sleeve 2023. One end of the second rotating rod 2027 is provided with a rotating shaft 2028, and the rotating shaft 2028 is rotatably mounted in the second sleeve 2025. A second screw 2026 is provided on the second sleeve 2025.

[0056] In one embodiment, the first sleeve 2023 is connected to the fixed shaft 2021 via a bearing.

[0057] In one embodiment, the second sleeve 2025 is connected to the rotating shaft 2028 via a bearing.

[0058] Tighten the first screw 2024, and the first sleeve 2023 and the fixed shaft 2021 cannot rotate. Loosen the first screw 2024, and the first sleeve 2023 and the fixed shaft 2021 can rotate.

[0059] Tighten the second screw 2026, and the second sleeve 2025 and the rotating shaft 2028 will not rotate. Loosen the second screw 2026, and the second sleeve 2025 and the rotating shaft 2028 will be able to rotate.

[0060] The detection component 203 includes a base 2031, which is mounted on the second rotating rod 2027. A light rod 2032 is mounted on the base 2031, and a self-locking slider 2033 is mounted on the light rod 2032. A dial indicator 2035 is mounted on the slider 2033.

[0061] In one embodiment, the dial indicator 2035 is mounted on the slider 2033 via a rotating arm 2034, and the rotating arm 2034 is self-locking.

[0062] In practical use, the product is placed in the loading station body 1, the first screw 2024 and the second screw 2026 are loosened, and the first rotating rod 2022 and the second rotating rod 2027 are rotated so that the measuring port of the dial indicator 2035 contacts the product. The first screw 2024 and the second screw 2026 are then tightened to fix the dial indicator 2035. The rotating component of the loading station body 1 drives the product to rotate, and the roundness of the product is measured by the dial indicator 2035. The support component 201 does not contact the loading station body 1, so the vibration generated by the loading station body 1 has minimal impact on the support component 201. Furthermore, the support component 201 is equipped with a shock-absorbing pad 2014 and a shock-absorbing block 2015, which can reduce the impact of vibration on the dial indicator 2035, making the measurement of the dial indicator 2035 more accurate.

[0063] Example 2: The difference from Example 1 is that, as shown in Example 2... Figure 7 , Figure 8 As shown, the position changing component is a copper or aluminum sheet 3; the detection component 203 is mounted on the copper or aluminum sheet 3. In actual use, the product is placed in the loading station body, and the copper or aluminum sheet 3 is rotated so that the measuring port of the dial indicator 2035 contacts the product. The rotating component of the loading station body drives the product to rotate, and then the roundness of the product is measured by the dial indicator 2035.

[0064] This type of position-changing component is bendable and can be shaped after bending. Compared to the previous technical solution, it is more efficient and simpler to operate, eliminating the need for tightening and loosening screws and rotating the rotating rod, while the accuracy is almost unaffected. The only drawback is that the replacement frequency of the copper or aluminum sheet is slightly higher. Moreover, this method is as widely applicable as the previous technical solution, and can be bent to different degrees according to the product size in the loading station to achieve contact between the dial indicator measuring port and the product.

[0065] Example 3: The difference from Example 1 is that, as shown in Example 3... Figures 9 to 18 As shown (for ease of illustration), Figure 11 The limiting rod and connecting lever are not shown. Figure 17 , Figure 18(The dashed line in the diagram shows the position of the bracket and the straight rod after rotation). The support assembly includes a bracket, which includes two vertical columns 4. The loading station body 1 has an opening larger than the detection mechanism. One vertical column 4 is rotatably set via a rotating shaft fixed to the ground. The position changing component is rotatably set relative to the other vertical column. The position changing component is a rotating assembly, a copper sheet, or an aluminum sheet. The rotating assembly is a straight rod 5. A dial indicator 2035 is fixedly connected to the straight rod with its measuring port facing the product to be tested.

[0066] A large opening is provided on the side wall of the loading station body near the detection mechanism to allow the support to rotate and partially enter the loading station body; the support assembly rotates, and the position changing component is rotated relative to the support assembly. The rotation point of the support assembly is one column of the support, and the rotation point of the position changing component relative to the support assembly is the other column of the support (or the middle of the upper beam of the support); with this setting, the position of the dial indicator can be adjusted by rotating the support and then rotating the straight rod (the rotation angle of the straight rod and the support is adjusted in the opposite direction of rotation of the support and the straight rod and the support, and the two work together to ensure that the measuring port of the dial indicator is perpendicular to the measured cylindrical surface and is in radial contact).

[0067] The pivot corresponding to the vertical column is a stepped pivot, with the lower half being a large pivot and the upper half being a small pivot 6. A frustum-shaped rubber sleeve 7 is fixedly fitted on the large pivot, and an opening is provided on the vertical column 4. The maximum size of the whole consisting of the large pivot and the rubber sleeve 7 is adapted to the opening. A second pivot is fixedly installed on the vertical column (or the upper beam of the support) corresponding to the straight rod. The second pivot is also a stepped pivot, with the lower half being a large pivot and the upper half being a small pivot. A frustum-shaped rubber sleeve is fixedly fitted on the large pivot, and a second opening is provided on the straight rod. The maximum size of the whole consisting of the large pivot and the rubber sleeve of the second pivot is adapted to the second opening.

[0068] With this setup, when rotating the support, first lift the support to disengage the vertical column from the main shaft, then rotate it, and then lift the straight rod to disengage it from the main shaft of the second rotating shaft; once the support and straight rod are in the required position, press down the support and straight rod to ensure that their positions remain unchanged after rotation.

[0069] A limiting rod 8 is slidably installed on the inner side wall of the loading station body 1 near the straight rod. The end of the straight rod that is fixedly connected to the dial indicator is also fixedly connected to a connecting folding rod 9. An elastic ring is fixedly connected to the end of the limiting rod 8 away from the side wall of the loading station body 1. The elastic ring matches the connecting folding rod for being sleeved on the connecting folding rod.

[0070] The straight rod is hinged to the vertical column; the dial indicator measuring end moves back and forth when the bracket rotates (the direction of the back and forth movement is limited by the limiting rod, and the direction of the back and forth movement is consistent with the diameter direction of the product) to achieve contact between the dial indicator measuring port and the product, and the side of the dial indicator is perpendicular to the cylindrical surface being measured (radial contact); to better achieve this solution, an inner flange can be set at the end of the connecting folding rod to ensure that the elastic ring is stable and does not fall off after being sleeved on the connecting folding rod.

[0071] Example 4: The difference from Example 3 is that, as shown in Example 4... Figure 19 , Figure 20 As shown ( Figure 20 (The dashed line in the middle shows another working state schematic diagram). The end of the straight rod 5 that is fixedly connected to the dial indicator 2035 is also fixedly connected to the connecting folding rod 9. A photoelectric sensor is provided inside the loading station body 1. The transmitting end 10 of the photoelectric sensor is fixedly connected to the inner side wall of the loading station body near the support. The receiving end 11 of the photoelectric sensor is fixedly connected to the connecting folding rod 9. The photoelectric sensor is connected to the controller signal, and the controller is connected to the buzzer signal.

[0072] With this setup, the worker manually rotates the bracket and the straight rod until the transmitter and receiver of the photoelectric sensor align. The controller then activates a buzzer to alert the worker that the dial indicator is in the correct position, and roundness testing begins. This design is simple in structure and adjustment (because the dial indicator's side is perpendicular to the cylindrical surface being measured (radial contact), the bracket and straight rod rotate in opposite directions. The photoelectric sensor, combined with manual visual inspection, can be quickly adjusted to the required position. Once adjusted, the position remains unchanged due to resistance during rotation). There is no risk of the limit rod sliding or getting stuck.

[0073] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
