[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 11As shown in the figure, the present invention provides a mold size detection device, which includes a frame 1. A dual-axis drive platform and a liftable carrier 2 are respectively installed on the frame 1. A detection frame 3 that can move in two axes is installed on the dual-axis drive platform. A station rotating frame 5 driven by a rotating motor 4 is rotatably installed on the detection frame 3. A laser scanner 6, a vision acquisition probe 8, an ultraviolet curing lamp 9, a probe 10, a fluorescence imaging system 11, and a glue injection head 12 are respectively installed on the station rotating frame 5; The dual-axis drive platform includes a first radial drive module 29 installed vertically on the frame 1. A lift frame 30 is drivingly installed on the first radial drive module 29. An axial drive module 31 is installed on the lift frame 30. The axial drive module 31 is drivingly connected to the detection frame 3.

[0021] A second radial drive module 26 installed vertically is installed on the frame 1. The second radial drive module 26 is drivingly connected to the carrier 2; The dual-axis drive platform drives the lift frame 30 through the first radial drive module 29 to achieve vertical movement, and then enables the detection frame 3 to move horizontally along the axis with the help of the axial drive module 31. This allows the detection components such as the laser scanner 6 and the vision acquisition probe 8 installed on the station rotating frame 5 of the detection frame 3 to flexibly perform all-round detection on the mold and the fluorescent glue. During the mold size detection process, the laser scanner 6 first obtains high-precision three-dimensional data of the empty mold cavity and the mold, providing a basic framework for subsequent measurements; The vision acquisition probe 8 acquires images from different angles to help the operator intuitively understand the appearance of the mold, the filling and curing status of the fluorescent glue. These components work together to solve the problem that it is difficult to comprehensively and accurately obtain the mold size information by traditional detection methods. Compared with the prior art, this solution can achieve multi-dimensional and high-precision measurement, greatly improving the accuracy and comprehensiveness of mold size detection, reducing mold quality problems caused by measurement errors, and enhancing the overall quality and efficiency of mold production; After the mold 7 to be measured is placed on the placement table 34, the mold cavity is set vertically upward and in an empty original state; The laser scanner 6 obtains high-precision three-dimensional data of the empty mold cavity and the mold by emitting laser beams and measuring the time or phase change of the reflected light; After the fluorescent glue is cured and formed and placed in the glue frame 13, the laser scanner 6 obtains high-precision three-dimensional data of the surface of the formed fluorescent glue Subsequently, the external contour, dimensions and shape information of each part of the mold are accurately measured, providing basic data for subsequent analysis; The measurement probe measures the distance from the surface of the mold or the fluorescent glue, which can assist the laser scanner 6 to perform more accurate size measurement on the mold. Especially when measuring the depth, aperture and other dimensions of the internal structure of the mold, it provides more accurate distance data to calculate the key size parameters of the mold cavity; The visual acquisition probe 8 is used to obtain the image information of the mold and the fluorescent glue. Images are acquired from different angles to visually display the appearance of the mold, the filling condition of the fluorescent glue in the mold, and the state after curing. Through the analysis of the images, the overall condition of the mold, the uniformity of the distribution of the fluorescent glue, etc. can be preliminarily judged, providing a reference for subsequent precise measurement and analysis; The ultraviolet curing lamp 9 emits ultraviolet rays to provide the energy required for curing the fluorescent glue. After the fluorescent glue is injected into the mold, the ultraviolet curing lamp 9 is turned on, causing the fluorescent glue to undergo a photochemical reaction within a specific time and change from a liquid state to a solid state. Precise control of the irradiation time, intensity, and angle of the ultraviolet curing lamp 9 can ensure uniform curing of the fluorescent glue, guarantee the stability of the shape and size of the cured fluorescent glue, and facilitate accurate dimensional measurement; The probe 10 can directly contact the mold or the formed fluorescent glue to obtain more accurate physical parameters. For example, through the probe 10, mechanical properties such as the hardness and elastic modulus of the cured fluorescent glue can be measured. These parameters help analyze the quality of the fluorescent glue curing process and judge its impact on the mold dimensional measurement results. In addition, the probe 10 can also be used to detect microscopic defects on the mold surface, such as scratches and cracks, to further evaluate the quality of the mold.

[0022] After being excited by light of a specific wavelength, the fluorescence imaging system 11 captures the fluorescence image emitted by the fluorescent glue. Through the analysis of the fluorescence image, such as gray-scale analysis and color distribution analysis, information such as the concentration and thickness of the fluorescent glue at different positions in the mold can be determined. Combining the relationship between the fluorescence intensity and the characteristics of the colloid, the dimensional information of the mold cavity can be deduced. Especially for molds with complex internal structures, the dimensions of internal channels, holes, etc. can be measured by observing the distribution of fluorescence inside the mold, providing intuitive and crucial data support for mold dimensional measurement; The glue injection head 12 is responsible for precisely injecting the fluorescent glue into the mold cavity. Its design and operating parameters, such as the glue injection speed and the glue injection volume, are crucial for the filling effect of the fluorescent glue in the mold, ensuring that the fluorescent glue uniformly and completely fills the mold cavity, avoiding defects such as bubbles and voids, and laying a foundation for subsequent accurate measurement of the mold dimensions; The temperature and humidity probe 14 on the carrier 2 monitors the ambient temperature and humidity data in real time and feeds the data back to the central control host 28. After the measurement is completed, the heating plate 15 heats up according to the instruction of the central control host 28 to soften the formed fluorescent colloid stored in the glue frame 13, facilitating recycling through the fluorescent glue circulation system. The vibrator 16 is started when the fluorescent glue softens to prompt the fluorescent glue to quickly soften and flow out; After the laser scanner 6 and the vision acquisition probe 8 have finished measuring the empty injection mold and the mold cavity, the fluorescent glue is injected into the mold cavity. When the fluorescent glue is injected, the vibration motor 33 works to make the fluorescent glue evenly distributed in the mold cavity. After the fluorescent glue is injected, under the action of the ultraviolet curing lamp 9, the fluorescent glue cures. After the fluorescent glue cures, the fluorescence imaging system 11 performs a primary imaging on the fluorescent formed body in the mold cavity; After the primary imaging, the two sealing plates 22 are closed and the mold cavity is sealed. After sealing, the flipping frame 19 flips 180°. After the flipping frame 19 flips, the sealing plates 22 are opened, and the formed fluorescent colloid falls into the glue frame 13. Subsequently, the moving frame moves, and the fluorescence imaging system 11 performs a secondary fluorescence imaging on the separated fluorescent glue formed body, and the laser scanner 6 and the vision acquisition probe 8 perform a re-data acquisition on the formed fluorescent colloid; By measuring the specifications of the injection mold and the formed fluorescent glue, multiple measurements are carried out and the dimensions of the injection mold and the mold cavity in the injection mold are deduced inversely. When deducing inversely, the influence of curing conditions such as temperature, humidity, and curing time is calculated; After the size of the fluorescent glue is measured, the fluorescent glue is softened and recycled by heating through the heating plate 15; When measuring the size of the injection mold, through the angle setting of the flipping frame 19 and the spacing control of the two sealing plates 22, multi-faceted measurement of the injection mold can be achieved; When it is necessary to measure the bottom surface specifications of the injection mold, the injection mold can be temporarily transferred through the glue frame 13, and then the multi-faceted automatic measurement of the injection mold can be realized; A glue frame 13 and a temperature and humidity probe 14 are installed on the carrier 2. The bottom of the glue frame 13 is integrated with a heating plate 15 and a vibrator 16. The bottom of the glue frame 13 is connected with a fluorescent glue circulation system, and the glue injection head 12 feeds glue through the fluorescent glue circulation system; The fluorescent glue circulation system includes a glue tank 23 installed on the frame 1. The glue tank 23 stores fluorescent glue. A glue return pump is installed on the side of the glue tank 23. A return flow cover 24 is installed on the bottom surface of the glue frame 13. A plurality of regularly distributed glue return holes 25 communicating with the return flow cover 24 are opened on the bottom surface of the glue frame 13. The glue inlet port of the glue return pump is communicated with the return flow cover 24 through a hose. A glue supply pump is installed on the top of the glue tank 23. The glue outlet port of the glue supply pump is communicated with the glue injection head 12 through a glue supply hose 38. A stirrer is installed in the glue tank 23; When the fluorescent glue circulation system is working, the stirrer in the glue tank 23 continuously stirs the fluorescent glue to prevent it from precipitating or having uneven components. The glue feeding pump transports the fluorescent glue in the glue tank 23 to the glue injection head 12 through the glue feeding hose 38, ensuring that the glue injection head 12 can stably inject the fluorescent glue into the mold cavity. When the fluorescent glue is used up, the glue recycling pump is started, and the remaining or softened fluorescent glue in the mold cavity is recycled to the glue tank 23 through the glue recycling cover 24 and the glue recycling hole 25 at the bottom of the glue frame 13, realizing the recycling of the fluorescent glue. This system solves the problems of fluorescent glue waste and environmental pollution, and at the same time ensures the stable quality of the fluorescent glue during each glue injection. Compared with the prior art, it not only reduces the production cost, but also improves the resource utilization rate, conforms to the concept of green production, and ensures the stability of the fluorescent glue supply during the detection process, indirectly improving the accuracy and reliability of the mold size detection; A movable frame 17 is installed on the frame 1, and a linear drive module 27 is installed at the bottom of the frame 1. The linear drive module 27 is in driving connection with the frame 17; A turnover frame 19 driven by a turnover motor 18 is rotatably installed on the frame 17. A clamping member 20 and a bidirectional drive member 21 are installed on the turnover frame 19. A mold to be tested 7 is clamped on the clamping member 20. A mold cavity is provided in the mold to be tested 7, and the glue injection head 12 can feed the fluorescent glue into the mold cavity. Two symmetrically arranged and spacing-adjustable sealing plates 22 are drivingly installed on the bidirectional drive member 21. A scale ruler is fixedly arranged on the top surface of the sealing plate 22, and the two sealing plates 22 seal the mold cavity.

[0023] The clamping member 20 includes a clamping lead screw rotatably connected to the turnover frame 19. A clamping motor is installed on the turnover frame 19, and the output shaft end of the clamping motor is fixedly connected to the clamping lead screw. A first right-handed thread section and a first left-handed thread section are symmetrically arranged on the clamping lead screw. The pitches of the first right-handed thread section and the first left-handed thread section are the same. A clamping plate 32 is drivingly installed on both the first right-handed thread section and the first left-handed thread section. A set of vibration motors 33 are built into both clamping plates 32. A placement table 34 is fixedly installed on the turnover frame 19 and corresponding to the position between the two clamping plates 32; The mold to be tested 7 is placed on the placement table 34 of the clamping member 20 of the turnover frame 19. The clamping motor drives the clamping lead screw to rotate, and the first right-handed thread section and the first left-handed thread section on the lead screw drive the two clamping plates 32 to approach or move away synchronously, so as to firmly clamp the mold; A central control host 28 is installed on the frame 1. The central control host 28 has a built-in curing influence calculation model. The curing influence calculation model corrects the measured specification data of the molded fluorescent glue based on the data feedback from the temperature and humidity probe 14, the shrinkage coefficient of the fluorescent glue, and the curing time of the fluorescent glue. The injection head 12 is installed with a flow sensor and a pressure sensor. The laser scanner 6, the visual acquisition probe 8, the temperature and humidity probe 14, the data ends of the flow sensor and the pressure sensor are all data-connected to the central control host 28. The power of the ultraviolet curing lamp 9 is adjustable. The ultraviolet curing lamp 9 is used to control the curing process of the fluorescent glue. After the size of the fluorescent glue is measured, the central control host 28 controls the electric heating plate 15 to heat up to soften the cured fluorescent glue in the mold cavity. The softened fluorescent glue is recycled to the glue box 23 through the fluorescent glue circulation system. The central control host 28 dynamically adjusts the power of the ultraviolet curing lamp 9 according to the shrinkage coefficient and curing time of the fluorescent glue to compensate for the dimensional error during the curing process.

[0024] The flow sensor and pressure sensor on the glue injection head 12 monitor the flow and pressure data during the glue injection process in real time and transmit them to the central control host 28. The ultraviolet curing lamp 9 adjusts the power according to the instructions of the central control host 28 to accurately control the curing process of the fluorescent glue. The curing influence calculation model corrects the measured specification data of the molded fluorescent glue based on the data fed back by the temperature and humidity probe 14, the shrinkage coefficient of the fluorescent glue and the curing time. After the measurement is completed, the central control host 28 controls the electric heating plate 15 to heat up and recover the fluorescent glue. This solves the problem that traditional detection cannot accurately consider the impact of curing factors on the measurement results and the inaccurate control of fluorescent glue curing. Compared with the existing technology, it effectively improves the accuracy of mold size measurement and reduces the measurement error caused by curing factors. At the same time, it realizes the intelligent control of the fluorescent glue curing process and the accurate correction of the measurement data, thereby improving the intelligence level of the entire mold size detection equipment and the reliability of the detection results. The bidirectional drive member 21 includes a bidirectional screw rod rotatably connected to the flip frame 19. A drive motor is installed on the flip frame 19. The output shaft end of the drive motor is fixedly connected to the bidirectional screw rod. The bidirectional screw rod is respectively provided with a second positive thread segment and a second negative thread segment. The second positive thread segment and the second negative thread segment are respectively connected to the two sealing plates 22 for transmission.

[0025] The drive motor on the flip frame 19 drives the bidirectional screw to rotate. The second positive thread segment and the second negative thread segment on the screw drive the two sealing plates 22 to move synchronously in the same direction or opposite directions, respectively, thereby sealing and opening the mold cavity. The scale on the top surface of the sealing plate 22 allows the operator to intuitively understand the movement distance and spacing of the sealing plate 22 and accurately control the sealing effect. This solution solves the problem of loose mold cavity sealing, which causes fluorescent glue leakage and affects the measurement results. The cleaning component includes a negative pressure vacuum cleaner 35 installed on the inspection rack 3. The dust suction end of the negative pressure vacuum cleaner 35 is connected to a dust suction pipe 36. A dust removal brush ring 37 driven by a rotary motor 4 is rotatably installed on the inspection rack 3.

[0026] Before and after mold inspection, the rotary motor 4 on the inspection rack 3 drives the dust removal brush ring 37 to rotate, cleaning the surface or cavity of the mold, sweeping up impurities such as dust and debris. At the same time, the negative pressure vacuum cleaner 35 sucks up the impurities generated by the cleaning through the dust suction pipe 36. This solves the problem that impurities on the mold surface affect the detection accuracy, ensures good contact between the detection component and the mold surface or the fluorescent glue, avoids interference of impurities with measurement data. Compared with the prior art, it improves the accuracy of mold dimension detection, reduces measurement errors caused by impurities, keeps the detection equipment and the working environment clean, and extends the service life of the detection equipment. The fluorescence imaging system 11 includes a light source, a fluorescence camera, and a fluorescence image analysis module. The light source has a preset wavelength and adjustable light intensity. The light source is electrically connected to the central control host 28 and the light source parameters are adjusted through the central control host 28. The fluorescence camera is used to capture the fluorescence image of the fluorescent colloid and transmit the image data to the central control host 28. The fluorescence image analysis module performs gray-scale analysis and edge detection on the acquired fluorescence image. Under the control of the central control host 28, the light source emits light with a preset wavelength and adjustable light intensity, exciting the fluorescent glue to emit fluorescence. The fluorescence camera captures the fluorescence image of the fluorescent colloid and transmits it to the central control host 28. The fluorescence image analysis module performs gray-scale analysis and edge detection on the image. By analyzing the fluorescence image, information such as the concentration and thickness of the fluorescent glue at different positions in the mold can be determined, and then the dimension information of the mold cavity can be deduced. Especially for molds with complex internal structures, this solution solves the problem that it is difficult to measure the dimensions of the complex internal structures of molds by traditional detection means. Compared with the prior art, it provides an intuitive and effective method for measuring the dimensions of the complex internal structures of molds, improves the comprehensiveness and accuracy of mold dimension detection, and provides more reliable data support for mold production and quality control.
