[0018] The application will be described in further detail below with reference to the drawings and embodiments.

[0019] An automatic oiling method for the outer circle of the instrument, by moving the outer circle of the instrument 1 to a preset oil injection station, collecting the outer circle detection information and the pressure detection value, determining the position and specifications of the outer circle of the instrument 1, and dynamically generating the oil injection output parameters, realizing self-adaptive adjustment of the oil film thickness and coverage range, thereby improving the oiling quality of the outer circle of the instrument 1.

[0020] With reference to Figure 1 , the embodiment of the application discloses an automatic oiling method for the outer circle of the instrument, which comprises: S1: control a preset mechanical hand to clamp and move the outer circle of the instrument 1 to a preset oil injection station, and collect the outer circle detection information.

[0021] Among them, the mechanical hand refers to a device for clamping and moving the outer circle of the instrument 1. The oil injection station refers to a station for oiling the outer circle of the instrument 1. The mechanical hand and the oil injection station are both set in advance.

[0022] The outer circle detection information refers to various data information collected for the outer circle of the instrument 1 before oiling. The outer circle detection information is used to judge the specifications, position and other key parameters, and provides a basis for subsequent oiling operations.

[0023] The outer circle detection information includes outer circle images and outer circle weight values and the like. The outer circle image refers to the image corresponding to the detected single outer circle of the instrument 1, and the outer circle weight value refers to the weight value corresponding to the detected outer circle of the instrument 1.

[0024] The outer circle image is obtained by photographing the appearance image of the outer circle of the instrument 1 through the image acquisition device preset on the mechanical hand; and the outer circle weight value is detected and obtained by the weighing device preset on the oil injection station.

[0025] S2: generating the outer ring specification and the outer ring center position point according to the outer ring detection information.

[0026] The outer ring specification refers to a set of key parameter indicators for the instrument outer ring 1, used to represent its physical characteristics and size characteristics, and usually includes area, weight, density, height, width, etc. information, which is the core basis for determining the subsequent oiling parameters. The outer ring center position point refers to the center position corresponding to the four instrument outer rings 1 after being connected by the support strips 2.

[0027] Referring to Figure 2 , the four instrument outer rings 1 are simultaneously injection molded by the injection molding machine, the support strips 2 are injection molded and connected between the four instrument outer rings 1, and the four instrument outer rings 1 are symmetrically arranged in pairs about the outer ring center position point.

[0028] The outer ring specification and the outer ring center position point are generated by analyzing the outer ring detection information, which facilitates subsequent use.

[0029] In order to further ensure the rationality of the outer ring specification and the outer ring center position point, it is necessary to make further separate analysis and calculation on the outer ring specification and the outer ring center position point. The specific steps are described as follows.

[0030] Referring to Figure 3 , the method for generating the outer ring specification and the outer ring center position point includes the following steps: S21: retrieving the outer ring image and the outer ring weight value from the outer ring detection information.

[0031] The outer ring image and the outer ring weight value are retrieved from the outer ring detection information, which facilitates subsequent use.

[0032] S22: determining the outer ring area value according to the outer ring image and the preset image area coefficient.

[0033] The image area coefficient is a conversion coefficient for establishing the correspondence between the pixel area in the image and the actual physical area, which is obtained by pre-inputting by the operator. The outer ring area value refers to the actual area value corresponding to a single instrument outer ring 1.

[0034] The area corresponding to the outer ring image is retrieved as the image area value, and the product value between the image area value and the image area coefficient is calculated as the outer ring area value, which facilitates subsequent use.

[0035] S23: generating the comprehensive specification by combining the outer ring weight value and the outer ring area value.

[0036] The comprehensive specification refers to the specification corresponding to the instrument outer ring 1 selected by fusing the weight and area of the outer ring.

[0037] The comprehensive specification is generated by combining the weight value of the outer ring and the area value of the outer ring, so as to more comprehensively and accurately represent the overall characteristics of the outer ring, and provide a unified basis for subsequent process parameter setting.

[0038] To further ensure the rationality of the comprehensive specification, further separate analysis and calculation of the comprehensive specification are required, which will be described in detail by the following steps.

[0039] The generation method of the comprehensive specification includes the following steps: S231: Determine the area specification according to the area value of the outer ring.

[0040] The area specification refers to the specification selected according to the area value of the instrument outer ring 1.

[0041] The area value of the outer ring is matched with the preset specification database to match the specification of the instrument outer ring 1 corresponding to the area interval of the outer ring as the area specification, which is convenient for subsequent use.

[0042] The specification database pre-stores a comparison table of different outer ring area intervals and corresponding instrument outer ring 1 specifications, and the specification database is obtained by pre-input of the operator.

[0043] S232: Determine the weight specification according to the weight value of the outer ring.

[0044] The weight specification refers to the specification selected according to the weight value of the instrument outer ring 1.

[0045] The weight value of the outer ring is matched with the preset specification database to match the specification of the instrument outer ring 1 corresponding to the weight interval of the outer ring as the area specification, which is convenient for subsequent use.

[0046] The specification database pre-stores a comparison table of different outer ring weight intervals and corresponding instrument outer ring 1 specifications, and the specification database is obtained by pre-input of the operator.

[0047] S233: Determine the outer ring density value based on the weight value of the outer ring and the area value of the outer ring.

[0048] The outer ring density value refers to the density value of the instrument outer ring 1.

[0049] The area specification corresponding to the outer ring thickness value and the shape are retrieved by the area value of the outer ring, and then the volume value of the instrument outer ring 1 is calculated by selecting a suitable calculation formula according to the shape of the instrument outer ring 1 and calculating the area value and the thickness value of the outer ring. The quotient value between the weight value of the outer ring and the volume value of the instrument outer ring 1 is calculated, and the calculation result is taken as the outer ring density value, which is convenient for subsequent use.

[0050] S234: Determine the density specification based on the outer ring density value.

[0051] The density specification refers to the specification selected based on the density of the outer ring 1 of the instrument.

[0052] By querying and matching the outer ring density value with the preset specification database, the outer ring density value is matched to the instrument outer ring 1 specification corresponding to the outer ring density range as the area specification, which is convenient for subsequent use.

[0053] The specification database pre-stores a comparison table of different outer ring density intervals and corresponding instrument outer ring 1 specifications, and the specification database is obtained after pre-input by the operator.

[0054] S235: Determine the specification overlap by combining the area specification, weight specification, and density specification.

[0055] Specification overlap refers to the number and type of items that overlap between area, weight, and density specifications. Specification overlap includes both the type of overlap and the number of overlaps. The type of overlap refers to the type of item that overlaps, and the number of overlaps refers to the number of items that overlap.

[0056] By comparing the area specifications, weight specifications and density specifications one by one, and using the consistent comparison results as the specification overlap, it is convenient for subsequent use.

[0057] For example, when the area and weight specifications match, the overlapping categories are area and weight, with a value of two overlapping. When the area, weight, and density specifications all match, the overlapping categories are area, weight, and density, with a value of three overlapping. When the area, weight, and density specifications all don't match, the overlapping category is the default empty category, with a value of 0 overlapping.

[0058] S236: Generate selected specifications based on the specification overlap, and use the selected specifications as comprehensive specifications.

[0059] The selected specifications refer to the specifications corresponding to the selected specifications of the instrument outer ring 1 .

[0060] By analyzing the overlap of specifications, selected specifications are generated and used as comprehensive specifications to improve the accuracy of the obtained comprehensive specifications.

[0061] In order to further ensure the rationality of the selected specifications, it is necessary to conduct further separate analysis and calculation of the selected specifications, which is explained in detail through the following steps.

[0062] The method for generating the selected specification includes the following steps: S2361: retrieve the coincidence type and the coincidence number value from the specification coincidence case.

[0063] By retrieving the coincidence type and the coincidence number value from the specification coincidence case, subsequent use is facilitated.

[0064] S2362: determine whether the coincidence number value is less than a preset complete coincidence reference number value. If not, perform S2363; if yes, perform S2364.

[0065] The complete coincidence reference number value refers to the number value corresponding to the case where the area specification, the weight specification, and the density specification are all consistent. The complete coincidence reference number value is obtained by pre-input. In this embodiment, the complete coincidence reference number value is 3.

[0066] By determining whether the coincidence number value is less than the preset complete coincidence reference number value, it is determined whether the area specification, the weight specification, and the density specification are all consistent.

[0067] S2363: take the density specification as the selected specification.

[0068] When the coincidence number value is not less than the preset complete coincidence reference number value, it indicates that the area specification, the weight specification, and the density specification are all consistent at this time, so the density specification is directly taken as the selected specification, thereby improving the accuracy of the obtained selected specification.

[0069] S2364: generate a type specification by combining the coincidence number value and the coincidence type, and take the type specification as the selected specification.

[0070] The type specification refers to the specification selected according to the coincidence type.

[0071] When the coincidence number value is less than the preset complete coincidence reference number value, it indicates that the area specification, the weight specification, and the density specification are all consistent at this time, so the coincidence number value and the coincidence type are combined and analyzed to generate a type specification, and the type specification is taken as the selected specification, thereby improving the accuracy of the obtained selected specification.

[0072] In order to further ensure the rationality of the type specification, it is necessary to make a further separate analysis and calculation on the type specification, which will be described in detail by the following steps.

[0073] The generation method of the type specification includes the following steps: S23641: when the coincidence number value is less than the preset coincidence reference number value, select the largest specification from the area specification, the weight specification, and the density specification as the largest specification.

[0074] The coincident reference number value refers to the minimum number value corresponding to the coincident specification. The coincident reference number value is obtained after pre-input. In this embodiment, the coincident reference number value is 2. The maximum specification refers to the specification with the largest size parameter among the area specification, the weight specification, and the density specification.

[0075] When the coincident number value is less than the preset coincident reference number value, it indicates that the area specification, the weight specification, and the density specification are all inconsistent at this time. Therefore, the maximum specification among the area specification, the weight specification, and the density specification is selected as the maximum specification, which is convenient for subsequent use.

[0076] S23642: Determine whether the maximum specification is the density specification. If yes, perform S23643; if no, perform S23644.

[0077] The maximum specification is determined by judging whether the maximum specification is the density specification, thereby determining whether the maximum specification can be directly selected.

[0078] S23643: The maximum specification is selected as the category specification.

[0079] When the maximum specification is the density specification, it indicates that the specification selected according to the density can meet the requirements of the area and the weight at this time. Therefore, the maximum specification is selected as the category specification, thereby improving the accuracy of the obtained category specification.

[0080] S23644: Determine the maximum difference value according to the maximum specification and the density specification.

[0081] The maximum difference value refers to the sequence number difference between the maximum specification and the density specification.

[0082] When the maximum specification is not the density specification, it indicates that the specification selected according to the density cannot meet the requirements of the area and the weight at this time. Therefore, the maximum specification and the density specification are input into the preset specification database to query the specification sequence numbers corresponding to the two, respectively. The difference between the specification sequence number corresponding to the maximum specification and the specification sequence number corresponding to the density specification is calculated and used as the maximum difference value.

[0083] The specification database pre-stores the specification sequence numbers corresponding to different instrument outer rings 1 specifications. The specification database is obtained after pre-input by an operator.

[0084] S23645: Determine the maximum adjustment information according to the maximum difference value.

[0085] The maximum adjustment information refers to the adjustment information corresponding to the adjustment of the specification according to the maximum difference value. The maximum adjustment information is used for adjusting and optimizing the specification.

[0086] The maximum difference is taken as the adjustment range to obtain the maximum adjustment information, facilitating subsequent use.

[0087] S23646: Based on the maximum adjustment information, the maximum specification is adjusted to form an adjusted specification, and the adjusted specification is taken as the category specification.

[0088] The adjusted specification refers to the specification corresponding to the adjusted specification.

[0089] The maximum specification is adjusted according to the maximum adjustment information to obtain the adjusted specification, and the adjusted specification is taken as the category specification, improving the accuracy of the obtained category specification.

[0090] In order to further ensure the rationality of the category specification, it is necessary to make further separate analysis and calculation on the category specification, which will be described in detail as follows.

[0091] The method for generating the category specification further includes the following steps: S23651: When the coincidence number value is not less than the preset coincidence reference number value, determine whether the coincidence category contains the preset density category. If yes, execute S23652; if no, execute S23653.

[0092] When the coincidence number value is not less than the preset coincidence reference number value, it means that the area specification, weight specification and density specification are consistent at this time, so whether the density specification can be directly used is determined by judging whether the coincidence category contains the preset density category.

[0093] S23652: Take the density specification as the category specification.

[0094] When the coincidence category contains the preset density category, it means that the density specification can be directly used at this time, so the density specification is taken as the category specification, thereby improving the accuracy of the obtained category specification.

[0095] S23653: Determine the coincidence specification according to the coincidence category.

[0096] The coincidence specification refers to the specification corresponding to the coincidence category.

[0097] When the coincidence category contains the preset density category, it means that the density specification can be directly used at this time, so the specification corresponding to the coincidence category is taken as the coincidence specification, facilitating subsequent use.

[0098] S23654: Determine the coincidence deviation value by combining the coincidence specification and the density specification.

[0099] The coincidence deviation value refers to the serial number difference between the coincidence specification and the density specification.

[0100] Therefore, by inputting the coincidence specification and the density specification into the preset specification database, the two corresponding specification serial numbers are queried, and the difference between the specification serial number corresponding to the coincidence specification and the specification serial number corresponding to the density specification is calculated as the coincidence deviation value.

[0101] S23655: determining the coincidence adjustment information according to the coincidence deviation value.

[0102] The coincidence adjustment information refers to the adjustment rule corresponding to the adjustment of the specification according to the coincidence deviation value.

[0103] The coincidence deviation value is used as the adjustment range to obtain the coincidence adjustment information, which is convenient for subsequent use.

[0104] S23656: adjusting the density specification based on the coincidence adjustment information to form a change specification, and taking the change specification as the category specification.

[0105] The change specification refers to the specification corresponding to the adjustment of the density specification.

[0106] The density specification is adjusted according to the coincidence adjustment information to obtain an adjustment specification, and the adjustment specification is taken as the category specification, thereby improving the accuracy of the obtained category specification.

[0107] S24: determining an image center point according to the outer ring image.

[0108] The image center point refers to the center position corresponding to the four instrument outer rings 1 determined according to the outer ring image.

[0109] The position corresponding to the outer ring image is determined to determine the image center position corresponding to the four outer ring images, and then the actual position is determined according to the image center position and a preset image position coefficient as the image center point, which is convenient for subsequent use.

[0110] S25: determining an actual position point by the image center point and the comprehensive specification, taking the actual position point as the outer ring center position point, and taking the comprehensive specification as the outer ring specification.

[0111] The actual position point refers to the position point corresponding to the adjustment of the specification.

[0112] The comprehensive specification is input into a preset position adjustment database to match a position adjustment parameter, the position adjustment parameter is used to adjust the image center point to obtain the actual position point, the actual position point is taken as the outer ring center position point, and the comprehensive specification is taken as the outer ring specification. Therefore, the accuracy of the obtained outer ring center position point and the outer ring specification is improved.

[0113] The position adjustment database pre-stores a comparison table of different comprehensive specifications and corresponding position adjustment parameters, and the position adjustment database is pre-set according to actual requirements.

[0114] S3: determining the oil injection movement parameter according to the outer ring specification.

[0115] The oil injection movement parameter refers to a movement related parameter of the oil injection device in the operation process, including a movement path, a movement speed, a start / endpoint position, a coverage range, etc., and is used to ensure that the oil injection accurately covers the area to be treated of the outer ring.

[0116] The oil injection movement parameter is matched by inputting the outer ring specification into the preset movement parameter database, and is convenient for subsequent use.

[0117] The movement parameter database pre-stores a comparison table of different outer ring specifications and corresponding oil injection movement parameters, and the movement parameter database is pre-set by an operator according to actual requirements.

[0118] S4: controlling the preset oil injection device to move to the center position point of the outer ring, and then controlling the preset oil injection device to move downward according to the oil injection movement parameter, and collecting a pressure detection value in real time.

[0119] The pressure detection value refers to a pressure value received when the oil injection device moves downward.

[0120] Referring to Figure 4 , the oil injection device includes a placement base 3, an oil injection plate 4, and a downward pressing mechanism 5. The oil injection plate 4 is provided with a placement cavity 6 for placing the instrument outer ring 1, and a plurality of oil injection openings are pre-provided on the cavity wall of the placement cavity 6 for uniformly coating oil. The placement base 3 is provided with a buffer table on the side close to the oil injection plate 4 for placing the instrument outer ring 1 and moving downward when subjected to external pressure. The buffer table can include a placement plate for placing the instrument outer ring 1 and a buffer spring pre-provided on the side of the placement plate close to the placement base 3 for buffering. The downward pressing mechanism 5 continues to move while pressing the instrument outer ring 1 after abutting against the instrument outer ring 1. The position where the downward pressing mechanism 5 abuts against the instrument outer ring 1 is provided with a pressure sensor. When the downward pressing mechanism 5 abuts against the instrument outer ring 1 and continues to press downward, the pressure sensor detects a pressure detection value at this time.

[0121] The preset oil injection device is controlled to move to the center position point of the outer ring, and then the preset oil injection device is controlled to move downward according to the oil injection movement parameter, so that oil injection on the instrument outer ring 1 starts at the same time as the downward pressing, and a pressure detection value is collected in real time.

[0122] S5: generating an oil injection output parameter in combination with the pressure detection value and the outer ring specification.

[0123] The fuel injection output parameter refers to an output pressure and a dwell time of the fuel injection device for injecting fuel.

[0124] The fuel injection output parameter is generated by analyzing the pressure detection value and the outer ring specification, facilitating subsequent use.

[0125] In order to further ensure the rationality of the fuel injection output parameter, further separate analysis and calculation of the fuel injection output parameter are required, which will be described in detail through the following steps.

[0126] Referring to Figure 5 , the method for generating the fuel injection output parameter further includes the following steps: S51: retrieving an outer ring height value and a corresponding outer ring width value from the outer ring specification.

[0127] The outer ring height value refers to the height value corresponding to the instrument outer ring 1. The outer ring width value refers to the width value corresponding to the instrument outer ring 1 at the height corresponding to the outer ring height value. The outer ring specification includes the outer ring height value and the outer ring width value.

[0128] The outer ring height value and the corresponding outer ring width value are retrieved from the outer ring specification, facilitating subsequent use.
