Description

Technical Field

[0001] This invention relates to the field of new energy vehicle parts processing technology, specifically a support device for automated processing of new energy vehicle parts. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source and incorporate advanced technologies in vehicle power control and drive systems, resulting in vehicles with advanced technological principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] With the continuous development of the economy and society, industry has developed rapidly, and people's requirements for various industries have greatly increased. For new energy vehicles, people have greatly increased the precision of new energy vehicle parts processing. In order to facilitate the testing of new energy vehicle parts, people have invented a carrier device for automated processing of new energy vehicle parts.

[0004] The existing patent application CN113245783B, entitled "A Carrying Device for Automated Processing of New Energy Vehicle Parts," describes a part carrying frame including a tilting bracket. An A1 adjustment unit adjusts the posture of the tilting bracket on a worktable. The A1 adjustment unit includes a drive shaft mounted on the tilting bracket and rotatably mounted on a drive seat. A drive component that drives the drive shaft to rotate is provided on the worktable. Carrying portions for supporting parts A are spaced along the length of the tilting bracket and movably mounted on it. An A2 adjustment unit is provided on the tilting bracket to adjust the posture of the carrying portions. This equipment can produce multiple required automotive parts at once, with high processing efficiency, effectively meeting the processing needs of this type of automotive part.

[0005] However, based on the above content and existing technology, the bearing device described in the above patent is mainly used in the processing of equipment, mainly to make the processing of equipment more convenient and improve the processing accuracy and efficiency of equipment.

[0006] However, the above-mentioned solution has significant drawbacks in practical use. It cannot be applied to the preliminary inspection of new energy vehicle parts. Currently, the preliminary inspection solution involves identifying new energy vehicle parts from the corresponding identification equipment, affixing the corresponding labels, and then sorting them through sorting equipment. The equipment is connected sequentially by conveyor belts. The entire process requires a very large area, a lot of equipment, and is relatively expensive, which does not meet people's usage requirements. Therefore, we have developed a carrier device for the automated processing of new energy vehicle parts. Summary of the Invention

Detailed Implementation

[0079] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0080] Research Reasons

[0081] The existing carrier devices are mainly used for preliminary testing scenarios that cannot be applied to new energy vehicle parts. The current preliminary testing solution involves identifying new energy vehicle parts from the corresponding identification equipment, then affixing the corresponding labels, and then sorting them through sorting equipment. The equipment is connected in sequence by conveyor belts. The whole process requires a very large area, a lot of equipment, and is relatively expensive.

[0082] To improve this method, initially, the testing equipment was set up on both sides of the conveyor belt. The conveyor belt moved while testing was performed. After each test, a set of data was recorded. At the end of the conveyor belt, a robotic arm picked up the new energy vehicle parts and transferred them to the corresponding equipment. (Different processing effects require different treatments. For example, new energy vehicle parts with poor processing effects need to undergo secondary processing such as repair.)

[0083] However, in actual use, after repeated verification, this method still requires multiple processing positions and the cooperation of multiple sorting robotic arms. In order to ensure comprehensive inspection during the inspection process, robotic arms are also required (without precise positioning by robotic arms, there will be large positional deviations of new energy vehicle parts and a large amount of data to be processed during inspection). Therefore, the whole process requires a lot of equipment and the cost is relatively high.

[0084] Finally, based on the existing processing support equipment, further research and development will be conducted to design a support device that is convenient for inspection and has sorting functions.

[0085] Research Plan

[0086] A support device for automated processing of new energy vehicle parts, such as Figure 1-7 As shown, the system includes a base 1, a detection component 3, a conveyor 4, and a pushing component. A rotating platform 2 is mounted on the base 1. The detection component 3 is installed at the upper middle position of the rotating platform 2. The detection component 3 has a detection component for identifying the processing effect of new energy vehicle parts inside, and the detection component is electrically connected to the drive component in the rotating platform 2. The conveyor 4, used to transport the detected parts, is mounted on the base 1. One end of the conveyor 4 passes through the part outlet on the detection component 3 and extends into the interior of the detection component 3. A curtain can be installed at the part outlet to provide a light-blocking effect. The pushing component, used to push the detected new energy vehicle parts onto the conveyor 4, is mounted on the detection component 3. The base 1 is equipped with a position recognition component for correcting the rotation angle of the rotating platform 2 and a support structure for supporting the rotating platform 2. The support structure is located outside the position recognition component.

[0087] The pushing component adopts a telescopic rod structure. The telescopic rod can be driven by electricity, pneumatics or hydraulics. A push plate is installed at the telescopic end of the telescopic rod. When the telescopic rod is in the retracted state, the push plate is located in the protective cylinder. When the telescopic end of the telescopic rod extends, the push plate moves and pushes the identified new energy vehicle parts onto the conveyor 4.

[0088] The rotating platform 2 has a trough-shaped structure, and the conveying component 4 is a conveyor belt. The conveyor belt is installed in the trough-shaped structure, thereby reducing air resistance when the rotating platform 2 rotates.

[0089] The support structure adopts a support frame, and a guide ball is rotatably installed at the top of the support frame through a pin. The guide ball is rotatably connected to an annular groove opened on the lower end face of the base 1.

[0090] The rotating platform 2 adopts a rotary table structure commonly used in this field, and uses a transmission method of motor, gear and gear ring, which makes the whole more stable (the motor output drives the gear to rotate, the gear meshes with the gear ring, thereby driving the rotating platform 2 to rotate. Therefore, it is not a direct drive method of motor connection. The lifting support directly passes through the rotating platform 2. Therefore, the lifting support will not rotate when the rotating platform 2 rotates).

[0091] The position recognition component uses a proximity sensor and a sensing plate. The sensing plate is installed on the outer side of the lower end face of the rotating part of the rotating platform 2, and the proximity sensor is installed on the bracket on the base 1.

[0092] The rotating platform 2 consists of a rotating part and a fixed part.

[0093] In use, the robotic arm picks up the processed new energy vehicle parts and places them into the detection component 3. After detection and identification by the detection component 3, the processing effect of the new energy vehicle parts is determined. Based on the processing effect, the rotating platform 2 is started. The rotating platform 2 changes the orientation of the conveyor 4, and then the pushing component pushes the new energy vehicle parts onto the conveyor 4. The conveyor 4 then transports the new energy vehicle parts to the corresponding position.

[0094] This invention describes a carrier device for automated processing of new energy vehicle parts. It changes the existing method of separate detection and sorting, and can realize the identification of the processing effect of new energy vehicle parts. Based on the identification result, the rotation angle of the rotating platform 2 is adjusted, and the identified new energy vehicle parts are transported to the corresponding conveyor belt through the conveyor 4 on the rotating platform 2. This realizes the integration of equipment, greatly reduces the space required by the equipment, improves the space utilization rate, and eliminates the need for sorting equipment, thus reducing costs. It has good performance and good application prospects.

[0095] The detection component 3 includes a protective cylinder and a lifting support. An opening for placing new energy vehicle parts is provided in the middle of the upper end face of the protective cylinder. The robotic arm places the new energy vehicle parts through this opening. The robotic arm is positioned at a fixed point, so the placed new energy vehicle parts are located in the center of the lifting support. The lifting support is set in the mounting hole in the middle of the interior of the rotating platform 2. When the rotating platform 2 rotates, it drives the protective cylinder to rotate around the lifting support. The lifting support is not connected to the rotating part of the rotating platform 2.

[0096] The lifting support includes a support platform 5, a lifting column 6, a guide cylinder 7, and a guide column 8. The support platform 5 is set in the mounting hole. The fixed end of the lifting column 6 is installed on the fixed part of the rotating platform 2. There are several groups of guide cylinders 7, which are arranged in a circular array and installed in the mounting hole. There are several groups of guide columns 8, which are arranged in a circular array and installed at the lower end of the support platform 5. The lifting column 6 is inserted into the inside of the guide column 8. The cooperation between the guide cylinder 7 and the guide column 8 can make the lifting more stable.

[0097] During the lifting process, the guide columns 8 are all inserted into the guide cylinder 7, but the insertion depth is different to ensure stability.

[0098] The detection components include an optical imaging component and a support sensing component;

[0099] The optical imaging component is installed on the inclined mounting surface near the upper end inside the protective cylinder, providing a wider angled imaging area; the support sensing component is set on the support platform 5; both the optical imaging component and the support sensing component are connected to the industrial control computer on the base 1 (which is present on existing mechanical equipment, so it will not be described in detail).

[0100] The optical imaging component and the support sensing component work together to determine the angle, thereby ensuring a consistent shooting position and improving the accuracy of data acquisition.

[0101] The optical imaging assembly includes an industrial camera 9 and an illumination ring 10. The industrial camera 9 is fixed on the mounting slope, and the illumination ring 10 is located outside the industrial camera 9.

[0102] The illumination ring 10 provides supplementary lighting, improving the clarity of the image and thus enhancing the accuracy of subsequent recognition.

[0103] The support sensing components include a weighing element and a direction sensing element;

[0104] The weighing component employs several sets of weighing sensors, which are arranged in a ring on the outer side of the upper end of the support platform 5. A direction sensing component is mounted on the support platform 5. The direction sensing component includes a flexible pressure film sensor 11, a support plate 12, an elastic support component, and a limiting ring 14. The flexible pressure film sensor 11 is mounted in the middle of the upper end face of the support platform 5. The support plate 12 is mounted on the upper end of the weighing sensor, and an electromagnet 13 is fixedly mounted on the outer side of the upper end face of the support plate 12.

[0105] The number of elastic support members is several sets, and the lower end of the elastic support member passes through the through hole opened at the upper end of the support plate 12.

[0106] The limiting ring 14 is located at the upper end of the support plate 12, and the upper end of the elastic support member passes through the limiting ring 14.

[0107] The elastic support includes a prism 15, a compression column 16, and a spring 17;

[0108] The elastic force of spring 17 is set according to the weight of the new energy vehicle parts. The weight of the new energy vehicle parts themselves will not cause the deformation of spring 17 to be within 1 mm, thus ensuring that the new energy vehicle parts can move freely at the top of prism 15. At this time, the weighing sensor can play a precise weighing role.

[0109] The force applied by gravity and the magnetic effect of electromagnet 13 causes spring 17 to deform, at which point the extrusion column 16 will come into contact with the flexible pressure film sensor 11.

[0110] The flexible pressure film sensor 11 converts the pressure signal into an electrical signal, which can clearly determine the pressure position and thus the orientation of the product. Then, it determines the angle between the orientation of the product and the orientation of the industrial camera 9, and adjusts the direction of the rotating platform 2 accordingly, thereby changing the orientation of the industrial camera 9 so that the orientation of the industrial camera 9 is opposite to the orientation of the product, and then begins data acquisition.

[0111] The side end faces of adjacent prisms 15 are fitted together, and the upper end pieces of all prisms 15 form a plane;

[0112] The smaller the area of ​​the upper surface of prism 15, the higher the detection accuracy. The area of ​​the upper surface of prism 15 must not exceed 1 square centimeter.

[0113] The upper end of the extrusion column 16 is fixedly connected to the lower end face of the prism 15. The lower end face of the prism 15 passes through the through hole on the support plate 12. The support plate 12 is designed to prevent the prism 15 from moving excessively and to protect the flexible pressure film sensor 11.

[0114] Spring 17 is sleeved on the outside of extrusion column 16, and the upper and lower end faces of spring 17 are fixedly connected to the lower end face of prism 15 and the upper end face of support plate 12, respectively.

[0115] Spring 17 provides some support.

[0116] During the detection process, the electromagnet 13 generates a magnetic force that pulls the new energy vehicle parts downward, squeezing the prism 15, so that the squeezing column 16 comes into contact with the flexible pressure film sensor 11.

[0117] This invention describes a carrier device for automated processing of new energy vehicle parts, which includes a detection component. The direction sensor in the detection component can identify the position of the new energy vehicle parts. In conjunction with the rotation of the rotating platform 2, it can ensure that the initial position and angle of all new energy vehicle parts are the same, thereby making the captured images identical. This improves the accuracy of the acquired data, facilitates subsequent data processing, saves some data processing steps, improves detection efficiency, and has good overall performance and promising application prospects.

[0118] A method for using a support device for automated processing of new energy vehicle parts, such as... Figure 8-9 As shown, it includes the following steps:

[0119] The robotic arm picks up the processed new energy vehicle parts and places them on the top of prism 15;

[0120] The weighing sensor weighs the new energy vehicle parts, obtains the weight Zl of the new energy vehicle parts, and sends the weight to the industrial control computer;

[0121] When the electromagnet 13 is activated, it generates a magnetic force that pulls the new energy vehicle parts downward, squeezing the prism 15 so that the squeezing column 16 comes into contact with the flexible pressure film sensor 11. The flexible pressure film sensor 11 then sends the detected data to the industrial control computer.

[0122] The industrial control computer analyzes the data detected by the flexible pressure film sensor 11, starts the rotating platform 2, and the rotating platform 2 drives the optical imaging component to the initial detection position.

[0123] The optical imaging assembly and rotating platform 2 are activated to take pictures and transmit the captured data to the industrial control computer;

[0124] The industrial control computer analyzes the weight and the captured data, and identifies the processing effect of new energy vehicle parts based on the weight and the captured data;

[0125] When the captured data is video, the captured data is processed by frame segmentation to divide the video into images. Alternatively, images can be captured directly by timed shooting, in which case frame segmentation is not required.

[0126] Acquire images at specified time points (e.g., take one photo every 0.5 seconds), convert the images to grayscale, and analyze them against a standard grayscale image to calculate the difference value Cyz.

[0127] Grayscale values ​​after converting the image to grayscale The calculation formula is as follows:

[0128]

[0129] In the formula, , , These are the color values ​​for each pixel.

[0130] The formula for calculating the difference value Cyz is as follows:

[0131]

[0132] In the formula, The number of regions where the grayscale values ​​of an image differ from those of a standard grayscale image after grayscale conversion. This represents the average grayscale value of the region where the grayscale values ​​differ from those of the standard grayscale image. This is the average grayscale value of the same area in a standard grayscale image. This represents the number of pixels in the region where the grayscale values ​​of the image differ from those of the standard grayscale image. The area of ​​the abnormal region can be directly determined by the number of pixels. This is a preset adjustment coefficient, a fixed value obtained through computer simulation. It is mainly to avoid the calculated data being too large and to facilitate staff judgment.

[0133] The area where the grayscale value difference between the image after grayscale conversion and the standard grayscale image is greater than 5 is defined as the area where the absolute value of the grayscale value difference is greater than 5. The smaller the grayscale value difference between the image after grayscale conversion and the standard grayscale image, the more standard it is. To improve accuracy, 5 can also be set to 3.

[0134] For example, if there are 10 photos, 5 of which have areas of difference, and one photo has 2 areas of difference, then... The value equals 6. The difference value needs to consider not only the difference at each point of difference, but also the sum of the areas.

[0135] The processing effect value Xgz is calculated based on the weight Zl and the difference value Cyz;

[0136] The formula for calculating the processing effect value Xgz is as follows:

[0137]

[0138] In the formula, and These are the weighting coefficients for weight difference and the weighting coefficients for difference value on the processing effect value, respectively. The standard weight for new energy vehicle parts , , and All are greater than 0.

[0139] The weighting coefficients are determined using the coefficient of variation method, which assigns weights to each indicator based on the degree of variation between the current value and the target value. If the numerical difference of an indicator is large, clearly distinguishing each evaluated object, it indicates that the indicator has rich discriminative information and should therefore be given a larger weight. Conversely, if the numerical difference of each evaluated object on a certain indicator is small, then the indicator's ability to distinguish each evaluated object is weak, and therefore it should be given a smaller weight. This method directly utilizes the information contained in each indicator to calculate the weight of the indicator, thus possessing objectivity.

[0140] After identifying the processing effect of the new energy vehicle parts, the industrial control computer compares the processing effect value Xgz with the set range to obtain the conveyor channel number, calculates the rotation angle, starts the rotating platform 2 to rotate to the corresponding conveyor channel, and pushes the component to push the new energy vehicle parts onto the conveyor 4 and then conveys them to the corresponding conveyor channel.
