Description

Technical Field

[0001] This invention relates to the field of size measuring equipment, and more particularly to a fully automatic size measuring device for a basin stand. Background Technology

[0002] CCD visual inspection technology and line laser inspection technology, as core means of industrial automation inspection, have been widely used in multi-dimensional quality control of product dimensions, surface defects, and geometric tolerances. CCD inspection equipment can achieve sub-pixel level precision measurement through high-resolution imaging and image processing algorithms (such as the line array CCD image inspection accuracy of up to 0.039%), while line laser inspection technology excels in non-contact three-dimensional contour scanning and is suitable for the inspection of complex curved surfaces.

[0003] In the prior art, CN113532400A discloses a multi-station CCD inspection device, but it relies on conveyor belt loading and unloading, making it unable to achieve high-precision sorting, and the inspection module is fixed, unable to expand multi-parameter inspection functions; CN218968922U proposes a laser spot positioning technology based on linear CCD, which improves the detection sensitivity, but is only suitable for spot position measurement in a single direction, and cannot cover the multi-faceted inspection needs of complex products. In addition, the integrated barcode scanning and line laser inspection solution of CN215823456U is difficult to adapt to the rapid switching of different inspection scenarios due to insufficient modular design.

[0004] Existing testing equipment typically only supports a single testing mode and cannot achieve integrated testing of multiple parameters. Multiple independent CCD and line laser devices need to be combined, resulting in complex production line layout, high costs, and low efficiency of multi-device collaboration.

[0027] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0028] Reference Figures 1-8A fully automatic size measuring device for a basin stand includes: a feeding mechanism 200 for orientationally conveying the product to be tested to the testing station; and a testing module disposed on one side of the feeding mechanism 200, wherein the testing module is sequentially configured with a barcode scanning unit 400, a front detection unit 500, a back detection unit 600, a side detection unit 700, and a laser detection unit 800 along the conveying direction, and each unit is synchronously triggered by a control system. The barcode scanning unit 400 includes a first camera 402 for reading product identification information and binding it to the testing data; the front detection unit 500 includes a second camera 501 for scanning the front of the product. The system includes a defect detection unit 600, which includes a third camera 606 and is used to detect defects on the reverse side of the product. The side detection unit 700 includes a fourth camera 705 and is used to scan the three-dimensional contour of the product. The laser detection unit 800 includes an upper laser scanning head 803 and a lower laser scanning head 804. The upper laser scanning head 803 is positioned above the lower laser scanning head 804, and the product passes between the upper and lower laser scanning heads 803 and 804. The upper and lower laser scanning heads 803 and 804 form a laser light curtain to measure the three-dimensional dimensions of the product in real time.

[0029] In this embodiment, the fully automatic size measurement equipment is mainly used for size measurement and defect detection of the basin rack. It realizes a fully automated process from product loading, barcode scanning, multi-face detection to unloading. The loading mechanism 200 is mainly responsible for directionally transporting the basin rack products to be tested to the detection station. The detection module is the core part of the equipment, which includes multiple detection units. Each unit is triggered synchronously by the control system to perform comprehensive detection on the basin rack.

[0030] The barcode scanning unit 400 is mainly used to read the product identification information of the basin rack and bind it with subsequent inspection data to facilitate product traceability and management. The front inspection unit 500 is used to inspect the front of the basin rack for defects such as surface scratches, cracks, and holes. The back inspection unit 600 is used to inspect the back of the basin rack for defects, and its working principle is similar to that of the front inspection unit 500. The side inspection unit 700 is used to scan the three-dimensional contour of the basin rack to obtain the shape and size information of the side of the basin rack. The laser inspection unit 800 is used to measure the three-dimensional dimensions of the basin rack in real time, such as height and thickness. Multiple inspection functions are integrated into one device to realize multi-parameter and all-round inspection of products, reduce the floor space and number of inspection devices, and improve the space utilization of the production site.

[0031] The feeding mechanism 200 includes: a storage bin 201 for storing products; a picking bin 202 disposed on one side of the storage bin 201; and a robotic arm 203 disposed above the picking bin 202, the robotic arm 203 being used to pick up products from the picking bin 202 and place them into the storage bin 201.

[0032] The aforementioned storage bin 201 is a container for storing tray rack products to be tested. Its design should be optimized according to the shape and size of the tray racks to ensure stable storage of multiple tray racks. A multi-layer structure or a specific arrangement can be adopted to facilitate subsequent material retrieval operations. The retrieval bin 202 is located on one side of the storage bin 201 and receives tray racks transferred from the storage bin 201. The function of the retrieval bin 202 is to perform preliminary sorting and positioning of the tray racks, facilitating the gripping of the robotic arm 203. Guiding devices or limiting structures can be installed within the retrieval bin 202 to ensure the tray racks are in the appropriate position and posture. The robotic arm 203 is mounted above the retrieval bin 202 and has multiple degrees of freedom, enabling it to flexibly retrieve tray rack products from the retrieval bin 202. The end effector of the robotic arm 203 can be equipped with specialized gripping tools, such as suction cups or grippers, selecting the appropriate gripping method based on the material and shape of the tray rack. Upon receiving instructions from the control system, the robotic arm 203 will precisely move to the designated position within the material handling bin 202, grab the tray, and place it into the transfer fixture 300.

[0033] It also includes a transfer fixture 300, which is disposed between the feeding mechanism 200 and the barcode scanning unit 400. The transfer fixture 300 includes a slide rail 301 and a transfer platform 302, wherein the transfer platform 302 is connected to the slide rail 301.

[0034] The aforementioned transfer fixture 300 is positioned between the loading mechanism 200 and the barcode scanning unit 400, serving as a transition and further positioning mechanism. The slide rail 301 provides a path for the transfer platform 302 to move, ensuring its accurate movement between different workstations. The slide rail 301 should possess high precision and stability to guarantee the positional accuracy of the tray during movement. The transfer platform 302 is connected to the slide rail 301 and is used to carry the tray transferred from the robot arm 203. Once the tray is placed on the transfer platform 302, the platform moves along the slide rail 301 to the detection position of the barcode scanning unit 400.

[0035] The scanning unit 400 further includes: a scanning frame 401, on which the first camera 402 is mounted; a first lens 403, on which the scanning frame 401 is mounted, and the first lens 403 is connected to the first camera 402; and a first light source 404, on which the scanning frame 401 is mounted, and the first light source 404 is disposed at one end of the first lens 403.

[0036] The barcode scanner 401 provides mounting support for the first camera 402, the first lens 403, and the first light source 404, ensuring their relative positions are fixed and guaranteeing scanning accuracy. The first camera 402 is the core scanning device, possessing high resolution and fast imaging capabilities, clearly capturing the marking information on the tray. The first lens 403 is connected to the first camera 402 and is used to adjust the focal length and angle of view, enabling the camera to accurately focus on the marking and improve the scanning success rate. The first light source 404 is installed at one end of the first lens 403, providing sufficient illumination for the scanning process. A suitable light source type, such as a white light source or a specific wavelength light source, can be selected based on the material and color of the marking to improve its contrast and clarity. When the tray moves with the transfer platform 302 to the detection position of the scanning unit 400, the first light source 404 illuminates, and the first camera 402, through the first lens 403, photographs the marking on the tray, reads the marking information, and transmits it to the control system.

[0037] The front detection unit 500 further includes: a first mounting bracket 506, on which the second camera 501 is mounted; a second lens 502, on which the second camera 501 is mounted; an upper light source 503, on which the upper light source 503 is mounted and positioned below the second lens 502; a lower light source 504, on which the lower light source 504 is mounted and positioned below the upper light source 503; and a first backlight source 505, on which the first mounting bracket 506 is mounted and positioned below the lower light source 504.

[0038] The aforementioned first mounting bracket 506 provides a mounting platform for the second camera 501, second lens 502, upper light source 503, lower light source 504, and first backlight 505, ensuring the accurate relative positions of each component. The second camera 501 has high-resolution and high-precision imaging capabilities, enabling it to clearly capture images of the front of the basin stand. The second lens 502 is used to adjust the focal length and angle of view, allowing the camera to clearly capture details of the front of the basin stand. The upper light source 503 illuminates the front of the basin stand from above, highlighting surface features and facilitating the detection of surface defects. The lower light source 504 is positioned above the upper light source 501. Below the 3rd light source, in conjunction with the upper light source 503, light is provided at different angles to reduce the influence of shadows and improve the accuracy of detection. The first backlight 505 is set below the lower light source 504 to provide uniform backlighting for detecting light transmission defects on the front of the basin frame, such as holes. When the product moves to the detection position of the front detection unit 500, the upper light source 503, the lower light source 504 and the first backlight 505 light up simultaneously. The second camera 501 takes pictures of the front of the basin frame through the second lens 502, and the acquired image data is transmitted to the control system for analysis to determine whether there are defects.

[0039] The reverse detection unit 600 further includes: a second mounting bracket 601, on which the third camera 606 is mounted; a second backlight 602, on which the third camera 606 is mounted; a product rack 603, on which the second mounting bracket 601 is mounted; a ring light source 604, on which the third camera 606 is mounted; and a third lens 605, on which the third camera 606 is mounted.

[0040] The second mounting bracket 601 provides mounting support for the third camera 606, the second backlight 602, the product rack 603, and the ring light source 604. The third camera 606 is used to capture images of the back of the basin stand. The second backlight 602 provides uniform backlighting to facilitate the detection of light transmission defects on the back. The product rack 603 is used to support the basin stand and position it in a suitable detection position. The ring light source 604 is mounted on the product rack 603 to illuminate the back of the basin stand from all sides, providing uniform illumination and reducing the influence of shadows. The third lens 605 is mounted on the third camera 606 and is used to adjust the focal length and viewing angle of the image. When the basin stand moves to the detection position of the back detection unit 600, the second backlight 602 and the ring light source 604 light up, and the third camera 606 captures images of the back of the basin stand through the third lens 605. The image data is transmitted to the control system for analysis.

[0041] The side detection unit 700 further includes: a base frame 701, on which the fourth camera 705 is mounted; a third backlight 702, on which the base frame 701 is mounted; a coaxial light source 703, on which the base frame 701 is mounted, and the coaxial light source 703 is disposed between the third backlight 702 and the fourth camera 705; and a fourth lens 704, on which the fourth camera 705 is mounted.

[0042] The base frame 701 provides a mounting foundation for the fourth camera 705, the third backlight 702, the coaxial light source 703, and the fourth lens 704. The fourth camera 705 has a 3D scanning function, which can quickly and accurately acquire the 3D contour data of the side of the basin stand. The third backlight 702 provides uniform backlighting to improve image contrast. The coaxial light source 703 is set between the third backlight 702 and the fourth camera 705 to provide illumination coaxial with the camera's optical axis and reduce interference from reflected light. The fourth lens 704 is mounted on the fourth camera 705 and is used to adjust the focal length and angle of view. When the basin stand moves to the detection position of the side detection unit 700, the third backlight 702 and the coaxial light source 703 light up. The fourth camera 705 scans the side of the basin stand through the fourth lens 704, and the acquired 3D contour data is transmitted to the control system for processing and analysis.

[0043] The laser detection unit 800 further includes: a connecting seat 801; a laser transfer shaft 802, which is mounted on the connecting seat 801, and the upper laser scanning head 803 and the lower laser scanning head 804 are mounted on the laser transfer shaft 802.

[0044] The connecting seat 801 provides mounting support for the laser transfer shaft 802, which is mounted on the connecting seat 801. The upper laser scanning head 803 and the lower laser scanning head 804 are mounted on the laser transfer shaft 802. The laser transfer shaft 802 can drive the laser scanning heads to move within a certain range to adapt to the inspection needs of different sized trays. The upper laser scanning head 803 and the lower laser scanning head 804 are respectively positioned above and below, forming a laser light curtain. When the tray passes between the upper laser scanning head 803 and the lower laser scanning head 804, the laser scanning heads emit laser beams. By detecting the reflection and obstruction of the laser beam, the three-dimensional dimensions of the tray are measured in real time, and the measurement data is transmitted to the control system.

[0045] It also includes: a base frame 100, a feeding mechanism 200, a transfer fixture 300, a barcode scanning unit 400, a front detection unit 500, a back detection unit 600, a side detection unit 700, and a laser detection unit 800 mounted on the base frame 100; and a unloading mechanism 900 mounted on the base frame 100.

[0046] The unloading mechanism 900 is installed on the base frame 100 and sorts and unloads the basin racks according to the test results. After the control system completes the analysis of various test data of the basin racks, it will determine whether the basin racks are qualified. If the basin racks are qualified, the unloading mechanism 900 will transport them to the qualified product storage area; if the basin racks are unqualified, the unloading mechanism 900 will transport them to the unqualified product storage area for further processing.

[0047] During use, the basin rack products to be tested are stored in the storage bin 201. The storage bin 201 is optimized according to the shape and size of the basin rack. It can stably store multiple basin racks using a multi-layer structure or a specific arrangement. The basin rack is transferred from the storage bin 201 to the picking bin 202. The guiding device or limiting structure in the picking bin 202 performs preliminary sorting and positioning of the basin rack, so that it is in a suitable position and posture, making it convenient for the robot arm 203 to grasp it.

[0048] After receiving instructions from the control system, the robotic arm 203 installed above the picking bin 202 moves precisely to the designated position inside the picking bin 202 with multiple degrees of freedom. Using special gripping tools such as suction cups or grippers at the end, it selects an appropriate method to grip the basin frame according to its material and shape, and places it on the transfer platform 302 of the transfer fixture 300.

[0049] The transfer platform 302 is connected to the slide rail 301, which provides a high-precision and stable movement path. After the tray is placed on the transfer platform 302, the transfer platform 302 moves along the slide rail 301 to the detection position of the barcode scanning unit 400. During this process, the tray is further positioned to ensure its positional accuracy.

[0050] When the tray rack arrives at the detection position of the barcode scanning unit 400 along with the transfer platform 302, the first light source 404 installed on the barcode scanning frame 401 lights up, providing sufficient illumination for barcode scanning. The first camera 402 adjusts its focus and viewing angle through the first lens 403 connected to it, accurately focusing on the marking on the tray rack. It clearly captures the marking information using high resolution and fast imaging capabilities, and transmits it to the control system. At the same time, the marking information is linked to subsequent detection data, facilitating product traceability and management.

[0051] When the tray is moved to the detection position of the front detection unit 500, the upper light source 503, the lower light source 504, and the first backlight source 505 mounted on the first mounting bracket 506 are lit simultaneously. The upper light source 503 illuminates the surface features from above, the lower light source 504 works with the upper light source 503 to reduce the influence of shadows, and the first backlight source 505 provides uniform backlighting to detect light transmittance defects.

[0052] The second camera 501 adjusts the focal length and viewing angle through the second lens 502 to clearly capture an image of the front of the basin stand. The acquired image data is transmitted to the control system for analysis to determine whether there are surface scratches, cracks, holes or other defects on the front of the basin stand.

[0053] When the basin stand reaches the detection position of the reverse detection unit 600, the second backlight 602 lights up to provide uniform backlighting, and the ring light source 604 illuminates the reverse side of the basin stand from all sides to provide uniform illumination and reduce the influence of shadows. The third camera 606 adjusts the focus and angle through the third lens 605 to capture an image of the reverse side of the basin stand. The image data is transmitted to the control system for analysis to detect whether there are defects on the reverse side. The working principle is similar to that of the front detection unit 500.

[0054] When the basin stand moves to the detection position of the side detection unit 700, the third backlight 702 lights up to provide uniform backlighting and improve image contrast. The coaxial light source 703 provides illumination coaxial with the camera's optical axis to reduce reflected light interference. The fourth camera 705 adjusts the focal length and viewing angle through the fourth lens 704 and uses its three-dimensional scanning function to quickly and accurately acquire the three-dimensional contour data of the side of the basin stand. The data is then transmitted to the control system for processing and analysis to obtain the shape and size information of the side of the basin stand.

[0055] The laser transfer shaft 802 on the connecting seat 801 drives the upper laser scanning head 803 and the lower laser scanning head 804 to a suitable position to adapt to the size of the basin stand. The upper laser scanning head 803 and the lower laser scanning head 804 are respectively positioned above and below, forming a laser light curtain. When the basin stand passes through the laser light curtain, the laser scanning head emits a laser beam. By detecting the reflection and obstruction of the laser beam, the three-dimensional dimensions of the basin stand, such as height and thickness, are measured in real time, and the measurement data is transmitted to the control system. After analyzing the various detection data of the basin stand, the control system determines whether the basin stand is qualified.

[0056] The unloading mechanism 900 installed on the base frame 100 sorts and unloads the products according to the judgment results: qualified basin racks are transported to the qualified product storage area; unqualified basin racks are transported to the unqualified product storage area for subsequent processing.

[0057] In summary, compared with existing technologies, it has the following beneficial effects: By integrating modules for barcode scanning, front and back visual inspection, 3D contour scanning, and laser thickness measurement, a fully automated operation process of automatic feeding, automatic inspection, and automatic unloading is achieved, improving the speed and efficiency of inspection.

[0058] Multiple testing functions are integrated into one device, enabling multi-parameter and all-round testing of products, reducing the footprint and number of testing devices, and improving the space utilization of the production site.

[0059] Therefore, although the invention has been described herein with reference to specific embodiments thereof, freedom of modification, various changes and substitutions are also within the scope of the foregoing disclosure, and it should be understood that in some cases, certain features of the invention may be adopted without departing from the scope and spirit of the invention and without corresponding use of other features.
