Description

Technical Field

[0001] The present invention relates to the technical field of testing equipment manufacturing, and in particular to a docking-type appearance photographing testing equipment and a product appearance photographing testing method. Background Art

[0002] In modern industrial production, product appearance quality inspection is a key step in ensuring product quality. Its inspection efficiency and accuracy have a significant impact on the competitiveness of manufacturers. Because product appearance inspection involves multiple inspection surfaces and items, and to meet the demands of a fast-paced market and improve production efficiency, equipment production cycles (CT) are generally short, typically requiring at least two sets of cameras for inspection. However, in actual production, frequent handling and handovers complicate operational logic, which can not only easily damage product parts but also cause misalignment in product positions, leading to poor results in back-end inspections. Furthermore, most traditional product appearance photography inspection equipment uses a single fixed-angle shooting method or a simple plane shooting method, which makes it difficult to conduct comprehensive, multi-angle inspections of the inner and outer sides of the product. Although some equipment can achieve multi-angle inspections, there are deficiencies in the clamping and positioning of product parts, and the transfer and connection between different inspection stations. This makes it difficult to adjust the product posture during the inspection process and the inspection process is not smooth. This not only affects the inspection efficiency, but also easily leads to blind spots in the inspection, which cannot meet the needs of high-precision appearance inspections. In addition, existing inspection equipment is often complex in structure, and there is a lack of effective coordination between the various functional parts, which increases the maintenance cost and operation difficulty of the equipment. Therefore, technical personnel are urgently needed to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to provide a docking type appearance photography inspection device, which can realize comprehensive inspection of products from multiple angles and reduce the number of product handling and handover times, so as to solve the above-mentioned problems existing in the prior art.

[0004] The present invention relates to a docking type appearance photographing inspection equipment, comprising: a left-placed clamping and correcting tool, a left-placed connecting tool, a left-placed photographing posture adjustment tool, a left-placed photographing unit, a right-placed photographing unit, a right-placed photographing posture adjustment tool, a right-placed connecting tool, and a right-placed clamping and correcting tool; The left-side clamping and alignment tool is used to clamp and position the product parts; The left-mounted docking fixture is used to receive the product parts transferred by the left-mounted clamping and straightening fixture, and dock with the left-mounted photographing posture adjustment fixture; The left-mounted camera posture adjustment tool drives the product to rotate to different angles and postures, and cooperates with the left-mounted camera unit to take photos and inspect the inner side of the product; The right-mounted camera posture adjustment tool directly receives the product parts that have completed the inner side photography operation transferred by the left-mounted camera posture adjustment tool, drives the product parts to rotate to different angles and postures, and cooperates with the right-mounted camera unit to take photos and inspect the outer side of the product parts; The right-placed connecting tooling is used to receive the product parts transferred by the right-placed photographing posture adjustment tooling and on which the internal and external side photographing operations have been completed, and to dock with the right-placed clamping and correction tooling.

[0005] As a further improvement to the technical solution disclosed in this invention, the docking-type appearance photography inspection equipment also includes a four-motor linear drive module. This module serves as the power source for the X-axis linear displacement motion of the left-mounted clamping and alignment fixture, the left-mounted camera posture adjustment fixture, the right-mounted camera posture adjustment fixture, and the right-mounted clamping and alignment fixture.

[0006] As a further improvement to the technical solution disclosed in the present invention, the left-mounted clamping and alignment fixture and the right-mounted clamping and alignment fixture have the same design structure. The left-mounted clamping and alignment fixture includes a left-mounted carrier, a left-mounted clamping and alignment fixture, and a left-mounted XY power unit. The number of left-mounted clamping and alignment fixtures is N, and they are linearly arrayed along the length of the left-mounted carrier, with N ≥ 1. With the help of the driving force of the left-mounted XY power unit, the left-mounted clamping and alignment fixture can achieve initial posture adjustment and clamping of the product.

[0007] As a further improvement of the technical solution disclosed in the present invention, the left-mounted clamping and correction fixture includes a left-mounted posture correction reference part, a left-mounted X-direction orientation calibration part, and a left-mounted Y-direction orientation calibration part. The left-mounted XY-direction power unit is composed of a left-mounted X-direction power sub-unit and a left-mounted Y-direction power sub-unit, which have independent working actions. A left-mounted positioning groove matching the bottom surface of the product part is formed on the left-mounted posture correction reference part, which is used for reference positioning when the product part is initially placed. The left-mounted X-direction orientation calibration part is driven by the driving force from the left-mounted X-direction power sub-unit and approaches the left-mounted posture correction reference part, so that the X-direction orientation of the product part can be calibrated; the left-mounted Y-direction orientation calibration part is driven by the driving force from the left-mounted Y-direction power sub-unit and approaches the left-mounted posture correction reference part, so that the Y-direction orientation of the product part can be calibrated.

[0008] As a further improvement to the technical solution disclosed in this invention, the left-mounted docking fixture comprises a gantry, a Z-axis sliding frame, a left-mounted indexing and holding device, and a left-mounted Z-axis power unit. The left-mounted indexing and holding devices are arranged in a linear array along the length of the Z-axis sliding frame. The left-mounted Z-axis power unit drives the Z-axis sliding frame to perform a reciprocating Z-axis lifting motion, enabling batches of product parts to be transferred from the left-mounted clamping and alignment fixture to the left-mounted camera posture adjustment fixture.

[0009] As a further improvement to the technical solution disclosed in this invention, the right-handed docking fixture includes a single-axis rotary machine and a right-handed indexing and holding device. The number of right-handed indexing and holding devices is N, where N ≥ 1, and they are arranged in a linear array along the length of the single-axis rotary machine. While the single-axis rotary machine is operating, the right-handed indexing and holding devices rotate circumferentially along its axis of rotation, allowing batches of product parts to be transferred from the right-handed camera posture adjustment fixture to the right-handed clamping and alignment fixture.

[0010] As a further improvement to the technical solution disclosed in this invention, the left-mounted camera posture adjustment fixture and the right-mounted camera posture adjustment fixture share the same design structure. The left-mounted camera posture adjustment fixture includes a left-mounted X-axis slide table, a left-mounted circumferential tilting frame, a left-mounted suction and positioning fixture, a left-mounted circumferential tilting power unit, and a left-mounted fixed-axis rotation power unit. The number of left-mounted suction and positioning fixtures is N, arranged in a linear array along the length of the left-mounted circumferential tilting frame, where N ≥ 1. The left-mounted X-axis sliding table is used to carry the left-mounted circumferential turning frame, and when it is displaced to the left limit position, the left-mounted adsorption and positioning fixture is aligned with the left-mounted docking tooling to receive the product, or when it is displaced to the right limit position, the left-mounted adsorption and positioning fixture is aligned with the left-mounted camera unit; after the product is fixed relative to the left-mounted adsorption and positioning fixture, the left-mounted circumferential turning power unit is operated, and the left-mounted circumferential turning frame together with the left-mounted adsorption and positioning fixture performs a circumferential turning motion. At the same time, the left-mounted fixed-axis rotation power unit is operated, and the left-mounted adsorption and positioning fixture drives the product to perform a fixed-axis circumferential rotation motion due to the action of the rotational torque.

[0011] As a further improvement of the technical solution disclosed in the present invention, the left-mounted circumferential flipping power unit is preferably a left-mounted reduction motor that is detachably fixed to the left-mounted X-direction sliding platform.

[0012] As a further improvement of the technical solution disclosed in the present invention, N≥4 and is an even number. The left-mounted fixed-axis rotation power unit includes a left-mounted rotating motor, a left-mounted primary synchronous belt transmission mechanism, a front left-mounted secondary synchronous belt transmission mechanism, and a rear left-mounted secondary synchronous belt transmission mechanism. The rotational torque generated by the left-mounted rotating motor is divided into two equal parts by the left-mounted primary synchronous belt transmission mechanism to the front left-mounted secondary synchronous belt transmission mechanism and the rear left-mounted secondary synchronous belt transmission mechanism. The front N / 2 left-mounted adsorption and positioning fixture is subjected to the rotational torque from the front left-mounted secondary synchronous belt transmission mechanism to synchronously perform fixed-axis circumferential rotation motion, and the rear N / 2 left-mounted adsorption and positioning fixture is subjected to the rotational torque from the rear left-mounted secondary synchronous belt transmission mechanism to synchronously perform fixed-axis circumferential rotation motion.

[0013] Furthermore, the present invention also discloses a method for inspecting the appearance of a product by photographing it, which is implemented by means of the above-mentioned docking-type appearance photographing inspection device and is characterized in that it includes the following steps: S1. The left-side clamping and straightening fixture receives the product to be inspected and completes the initial posture adjustment and clamping and fixing operations of the product through its own structural adjustment. S2. The left-positioned connecting tool receives the product from the left-positioned clamping and straightening tool, and transfers the product to the left-positioned photographing posture adjustment tool through translation and transfer actions; S3: The left-mounted camera posture adjustment tool drives the product to adjust its posture and switch to an angle and posture sequence that meets the requirements for inner side detection. Each time the product is adjusted to a photographic position, the left-mounted camera unit is triggered to take a photo of the inner side of the product to capture an appearance image. S4. Products that have completed the inner side inspection are directly taken over by the right-mounted camera posture adjustment tooling; S5. The right-mounted camera posture adjustment tool drives the product to adjust its posture and switch to an angle and posture sequence that meets the requirements for external surface detection. Each time the product is adjusted to a photographic position, the right-mounted camera unit is triggered to take a photo of the external surface of the product to capture an appearance image. S6. The right-positioned connecting tooling receives the product parts transferred from the right-positioned photographic posture adjustment tooling, which have completed photographic inspection on both the inner and outer sides, and transfers the product parts to the right-positioned clamping and straightening tooling again to prepare for the product part unloading operation or transfer to the next process.

[0014] In practical applications, the docking-type appearance photography inspection equipment disclosed in the present invention can achieve at least the following beneficial technical effects, specifically: 1) After the product is positioned by the left-mounted clamping and straightening fixture, it is connected and transferred by the left-mounted docking fixture. Then, it is driven by the left and right-mounted posture adjustment fixtures to adjust the posture of the product, enabling multi-angle photography of the inside and outside sides. This allows for precise docking and transfer of the product, significantly reducing the number of transfers during the inspection process, simplifying the action logic, effectively avoiding product damage and position consistency issues caused by frequent handling, and shortening transfer time, which is conducive to optimizing the inspection process CT. 2) In terms of inspection effectiveness, the left-mounted camera posture adjustment fixture and the left-mounted camera unit work together to inspect the inside of the product, while the right-mounted camera posture adjustment fixture and the right-mounted camera unit work together to inspect the outside of the product. Both can adjust the product to different angles and postures. This multi-angle, all-round inspection method effectively eliminates blind spots and ensures that every part of the product's appearance is carefully inspected, greatly improving the accuracy and comprehensiveness of appearance inspections. 3) Through reasonable tooling layout and inspection process design, while meeting the requirements of efficient and rapid production, the equipment volume is minimized, the equipment space utilization rate is improved, and the company's advantage in market competition is enhanced.

DETAILED DESCRIPTION

[0038] In the description of the present invention, it should be understood that the terms "left", "right", "front", "back", "up", "down", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0039] The present invention will be further described in detail below with reference to specific embodiments. Figures 1 to 5 The three-dimensional schematic diagram of the docking-type appearance photography inspection equipment disclosed in the present invention is shown together. It can be seen that it mainly consists of a machine (not shown in the figure), a left-mounted clamping and correction tooling 1, a left-mounted docking tooling 2, a left-mounted photo posture adjustment tooling 3, a left-mounted photo unit 4, a right-mounted photo unit 5, a right-mounted photo posture adjustment tooling 6, a right-mounted docking tooling 7, a right-mounted clamping and correction tooling 8, and a four-motor linear drive module 9. Among them, the machine provides a stable bearing and installation platform for each component of the equipment and is the basic architecture for the operation of the equipment. The four-motor linear drive module 9 serves as the power core for the linear displacement movement of the left-mounted clamping and correction tooling 1, the left-mounted photo posture adjustment tooling 3, the right-mounted photo posture adjustment tooling 6, and the right-mounted clamping and correction tooling 8 in the X direction (i.e., left and right directions), ensuring that each tooling can move accurately and stably in the horizontal direction, providing reliable power support for the equipment to achieve an efficient and orderly product inspection process. The left-placed clamping and alignment tooling 1 is used to clamp and position the product parts; the left-placed connecting tooling 2 is used to receive the product parts transferred by the left-placed clamping and alignment tooling 1, and to connect with the left-placed photographing posture adjustment tooling 3; the left-placed photographing posture adjustment tooling 3 drives the product parts to rotate to different angles and postures, and cooperates with the left-placed photographing unit 4 to take photographs and detect the inner side of the product parts; the right-placed photographing posture adjustment tooling 6 directly receives the product parts transferred by the left-placed photographing posture adjustment tooling 3 and whose inner side photographing operations have been completed, and drives the product parts to rotate to different angles and postures, and cooperates with the right-placed photographing unit 5 to take photographs and detect the outer side of the product parts; the right-placed connecting tooling 7 is used to receive the product parts transferred by the right-placed photographing posture adjustment tooling 6 and whose inner and outer side photographing operations have been completed, and to connect with the right-placed clamping and alignment tooling 8.

[0040] The product appearance photo inspection method mainly includes the following steps: S1. The left-side clamping and straightening tool 1 receives the product to be inspected and completes the initial posture adjustment and clamping and fixing operations of the product through its own structural adjustment; S2, the left-positioned transfer tool 2 receives the product from the left-positioned clamping and straightening tool 1, and transfers the product to the left-positioned photographing posture adjustment tool 3 through translation and transfer actions; S3: The left-mounted camera posture adjustment tool 3 drives the product to adjust its posture and switch to an angle and posture sequence that meets the requirements for inner side detection. Each time the product is adjusted to a photographic position, the left-mounted camera unit 4 is triggered to take a photo of the inner side of the product to capture an appearance image. S4. The product parts that have completed the inner side inspection are directly taken over by the right-mounted camera posture adjustment tool 6; S5. The right-mounted photographing posture adjustment tool 6 drives the product to adjust its posture and switch to an angle and posture sequence that satisfies the external surface detection. Each time the product is adjusted to a photographing position, the right-mounted photographing unit 5 is triggered to take a photo of the external surface of the product to collect an appearance image. S6. The right-side connecting tool 7 receives the product parts transferred from the right-side photographing posture adjustment tool 6, whose inner and outer sides have completed photographing inspection, and transfers the product parts to the right-side clamping and straightening tool 8 again to prepare for the product part unloading operation or transfer to the next process.

[0041] By adopting the above technical solution, on the one hand, after the product is positioned by the left-mounted clamping and straightening tool 1, it is connected and transferred by the left-mounted connecting tool 2, and then driven by the left-mounted camera posture adjustment tool 3 and the right-mounted camera posture adjustment tool 6 to adjust the camera posture, achieving multi-angle photography of the inner and outer sides, enabling precise docking and transfer of the product, significantly reducing the number of handling and handovers during the inspection process, simplifying the action logic, effectively avoiding product damage and position consistency problems caused by frequent handling, and shortening the transfer time, which is conducive to optimizing the inspection process CT; on the other hand, in terms of inspection effect, the left-mounted camera posture adjustment tool 3 and the left-mounted camera unit 4 cooperate to photograph and inspect the inner side of the product, while the right-mounted camera posture adjustment tool 6 and the right-mounted camera unit 5 cooperate to inspect the outer side of the product, and both can drive the product to adjust to different angles and postures. This multi-angle, all-round inspection method can effectively eliminate inspection blind spots and ensure that all parts of the product appearance can be carefully inspected, thereby greatly improving the accuracy and comprehensiveness of appearance inspection.

[0042] It is also important to emphasize here that reasonable design layout and testing process design, while meeting the requirements of efficient and rapid production, minimize the design volume of the photo inspection equipment and improve its space utilization, which helps companies complete product testing more efficiently and accurately, and enhance their advantages in market competition.

[0043] like Figure 6 As shown in the figure, as a preferred design, the left-mounted clamping and alignment fixture 1 includes a left-mounted platform 11, a left-mounted clamping and alignment fixture 12, and a left-mounted XY power unit 13. There are four left-mounted clamping and alignment fixtures 12 arranged in a linear array along the length of the left-mounted platform 11. With the driving force of the left-mounted XY power unit 13, the left-mounted clamping and alignment fixture 12 can achieve initial posture adjustment and clamping of the product.

[0044] like Figure 7 As shown in FIG, the left-positioned clamping and correcting fixture 12 includes a left-positioned attitude correction reference part 121, a left-positioned X-direction calibration part 122, and a left-positioned Y-direction calibration part 123. Figure 8As shown, the left-mounted XY power unit 13 consists of a left-mounted X-power subunit 131 and a left-mounted Y-power subunit 132, each of which performs independent work. The left-mounted posture correction reference member 121 is formed with a left-mounted positioning groove that matches the bottom surface of the product and serves as a reference for initial positioning of the product. In actual use, the left-mounted X-direction orientation calibration member 122 is driven by the driving force from the left-mounted X-direction power subunit 131 and approaches the left-mounted posture correction reference member 121, thereby calibrating the product's X-direction orientation. The left-mounted Y-direction orientation calibration member 123 is driven by the driving force from the left-mounted Y-direction power subunit 132 and approaches the left-mounted posture correction reference member 121, thereby calibrating the product's Y-direction orientation.

[0045] like Figure 9 As shown in FIG, the left X-direction power subunit 131 includes a left X-direction driving cylinder 1311 and a left X-direction driving beam 1312. Figure 10 As shown in the figure, the left-mounted Y-direction power subunit 132 includes a left-mounted Y-direction cylinder 1321 and a left-mounted Y-direction drive beam 1322. The left-mounted X-direction drive cylinder 1311 and the left-mounted Y-direction cylinder 1321 serve as the core of the power output, achieving stable telescopic movement through precise air pressure control. Their cylinders are securely mounted on the equipment's base structure, ensuring stable power output. The left-mounted X-direction driving beam 1312 is connected to the output end of the left-mounted X-direction driving cylinder 1311. When the left-mounted X-direction driving cylinder 1311 is started, the left-mounted X-direction driving beam 1312 is driven to perform smooth linear motion along the X-direction. At the same time, the left-mounted X-direction orientation calibration component 122 is fixed on the left-mounted X-direction driving beam 1312. As it moves synchronously with the left-mounted X-direction driving beam 1312, the left-mounted X-direction orientation calibration component 122 can accurately approach or move away from the left-mounted posture correction reference component 121, thereby achieving precise calibration of the X-direction orientation of the product and ensuring the accuracy and consistency of the product positioning in the X-direction. The left-placed Y-direction driving beam 1322 is connected to the output end of the left-placed Y-direction cylinder 1321. When the left-placed Y-direction cylinder 1321 is started, the left-placed Y-direction driving beam 1322 is driven to perform smooth linear motion along the Y-direction; at the same time, the left-placed Y-direction orientation calibration component 123 is fixed on the left-placed Y-direction driving beam 1322, and moves synchronously with it. The left-placed Y-direction orientation calibration component 123 can accurately approach or move away from the left-placed posture correction reference component 121, thereby realizing accurate calibration of the Y-direction orientation of the product part, and ensuring the accuracy and consistency of the product part's Y-direction positioning.

[0046] like Figure 17-21As shown in , as a preferred design, the right-mounted clamping and correction tooling 8 includes a right-mounted carrier 81, a right-mounted clamping and correction fixture 82, and a right-mounted XY-direction power unit 83. The right-mounted clamping and correction fixture 82 includes a right-mounted posture correction reference part 821, a right-mounted X-direction orientation calibration part 822, and a right-mounted Y-direction orientation calibration part 823. The right-mounted XY-direction power unit 83 is composed of a right-mounted X-direction power subunit 831 and a right-mounted Y-direction power subunit 832, which have independent working actions. The main design body of the right-mounted X-direction power subunit 831 includes a right-mounted X-direction drive cylinder 8311 and a right-mounted X-direction drive beam 8312. The main design body of the right-mounted Y-direction power subunit 832 includes a right-mounted Y-direction drive cylinder 8321 and a right-mounted Y-direction drive beam 8322. Compared with the left-mounted clamping and straightening tool 1, the right-mounted clamping and straightening tool 8 has a similar working principle, which will not be described here for the sake of space.

[0047] like Figure 11 As shown in the figure, the left-mounted docking fixture 2 is mainly composed of several parts, such as a gantry 21, a Z-direction sliding frame 22, a left-mounted transfer holding device 23 and a left-mounted Z-direction power unit 24. Among them, the gantry 21 serves as a supporting skeleton, providing a stable installation foundation for other components, ensuring the overall rigidity and stability of the left-mounted docking fixture 2 during operation. The Z-direction sliding frame 22 can be slidably installed on the left side of the gantry 21, and ensures the flatness and low friction of the sliding track. The number of left-mounted transfer holding devices 23 is 4, which are linearly arrayed along the length direction of the Z-direction sliding frame 22. The left-mounted transfer holding device 23 is preferably a vacuum suction cup to ensure reliable grasping of the product parts. The left-mounted Z-direction power unit 24 is preferably a linear motor, which can accurately control the Z-direction sliding frame 22 to perform Z-direction reciprocating lifting motion. By setting different lifting strokes and speed parameters, the layering and batch transfer of product parts can be achieved. When the Z-axis sliding frame 22 descends to the height of the left-mounted clamping and straightening tooling 1, the four left-mounted transfer holding devices 23 act synchronously to absorb the product parts; then, the Z-axis sliding frame 22 rises and translates horizontally to the top of the left-mounted photographing posture adjustment tooling 3, and then accurately aligns with it through the descending action, transferring the product parts batch by batch and stably to the left-mounted photographing posture adjustment tooling 3, ensuring the efficiency and accuracy of the product transmission process.

[0048] like Figure 16As shown in , as a preferred design, the right-mounted docking fixture 7 includes a single-axis rotary machine 71 and a right-mounted indexing and holding device 72, which work together to further optimize the transfer process of product parts after inspection. When the photo inspection equipment is in operation. The single-axis rotary machine 71 can accurately control the rotation angle and speed according to the preset program, providing stable and efficient power support for the transfer of product parts. The number of right-mounted indexing and holding devices 72 is 4, and they are linearly arrayed along the length direction of the single-axis rotary machine 71. The right-mounted indexing and holding device is preferably a vacuum suction cup. During the working period of the single-axis rotary machine 71, the right-mounted indexing and holding device 72 follows the rotating shaft 711 to perform circumferential rotation motion, and successively accurately grasps the product parts that have completed the internal and external side inspection from the right-mounted photo posture adjustment fixture 6, and rotates them to the top of the right-mounted clamping and straightening fixture 8, realizing the orderly transfer of product parts in batches, which not only improves the product flow efficiency, but also provides a strong guarantee for subsequent unloading operations or process connection, and further enhances the collaborative performance and work efficiency of the entire set of inspection equipment.

[0049] like Figure 12 、 Figure 13 As shown in , as a preferred design, the left-mounted photographing posture adjustment tool 3 includes a left-mounted X-axis sliding table 31, a left-mounted circumferential turning frame 32, a left-mounted adsorption and positioning fixture 33, a left-mounted circumferential turning power unit 34, and a left-mounted fixed-axis rotation power unit 35. There are four left-mounted adsorption and positioning fixtures 33, arranged in a linear array along the length of the left-mounted circumferential turning frame 32. The left-mounted X-axis sliding table 31 is capable of supporting the left-mounted circumferential turning frame 32 for stable and precise horizontal displacement. When the left-mounted X-axis sliding table 31 moves to the left limit position, the left-mounted adsorption and positioning fixture 33 it carries is precisely aligned with the left-mounted docking tool 2, reliably receiving the product transferred from the left-mounted docking tool 2 through vacuum adsorption or mechanical clamping. When the left-mounted X-axis sliding table 31 moves to the right limit position, the left-mounted adsorption and positioning fixture 33 is precisely aligned with the left-mounted photographing unit 4, creating conditions for subsequent photographic inspection. After the product is secured by the left-mounted suction and positioning fixture 33, the left-mounted circumferential flipping power unit 34 and the left-mounted fixed-axis rotation power unit 35 operate synchronously. The left-mounted circumferential flipping power unit 34 utilizes a left-mounted reduction motor (a servo motor coupled with a precision reducer) to drive the left-mounted circumferential flipping frame 32 and the left-mounted suction and positioning fixtures 33 in a circumferential flipping motion. Simultaneously, the left-mounted fixed-axis rotation power unit 35 provides stable torque to each left-mounted suction and positioning fixture 33, driving the product in a fixed-axis circumferential rotation. This combined flipping and circumferential rotation allows the product to be presented to the left-mounted camera unit 4 at multiple angles and in multiple positions, enabling comprehensive, no-blind-angle inspection of the product's interior surface, greatly improving inspection accuracy and reliability.

[0050] Likewise Figure 12 、 Figure 13As shown in the figure, as a preferred design, the left-mounted fixed-axis rotation power unit 35 includes a left-mounted rotary motor 351, a left-mounted primary synchronous belt drive mechanism 352, a front left-mounted secondary synchronous belt drive mechanism 353, and a rear left-mounted secondary synchronous belt drive mechanism 354. The left-mounted rotary motor 351, serving as the core power source, utilizes a high-torque, low-inertia servo motor with precise speed and torque control capabilities, enabling rapid response and stable power output according to testing requirements. The left-mounted primary synchronous belt drive mechanism 352, comprised of a synchronous belt and synchronous pulleys, leverages the toothed meshing characteristics of the synchronous belt to efficiently and stably divide the torque generated by the left-mounted rotary motor 351 into two equal parts: the front left-mounted secondary synchronous belt drive mechanism 353 and the rear left-mounted secondary synchronous belt drive mechanism 354. The front left-mounted secondary synchronous belt drive mechanism 353 and the rear left-mounted secondary synchronous belt drive mechanism 354 utilize a modular design, with symmetrical structures and independent operation, respectively driving the left-mounted adsorption and positioning fixture 33 at different locations. The two left-mounted adsorption and positioning fixtures 33 in the front position are driven by the front left-mounted secondary synchronous belt transmission mechanism 353. When the front left-mounted secondary synchronous belt transmission mechanism 353 is in operation, the rotational torque can be directly and stably transmitted to the left-mounted adsorption and positioning fixture 33, driving it to synchronously perform fixed-axis circumferential rotational motion. Similarly, the rear left-mounted adsorption and positioning fixture 33 is driven by the rear left-mounted secondary synchronous belt transmission mechanism 354, and achieves synchronous rotation under the drive of the rear left-mounted secondary synchronous belt transmission mechanism 354. In this way, not only can the power requirements of multiple left-mounted adsorption and positioning fixtures 33 working simultaneously be met, so that the product parts can be presented in a variety of postures during the inspection process, but also a more comprehensive and accurate shooting angle is provided for the left-mounted camera unit 4, effectively improving the accuracy and efficiency of the product inner side inspection.

[0051] like Figure 14 、 Figure 15 As shown in FIG, the right-mounted camera posture adjustment fixture 6 includes a right-mounted X-axis sliding platform 61, a right-mounted circumferential turning frame 62, a right-mounted suction and positioning fixture 63, a right-mounted circumferential turning power unit 64, and a right-mounted fixed-axis rotation power unit 65. Specifically, the right-mounted fixed-axis rotation power unit 65 includes a right-mounted rotary motor 651, a right-mounted primary synchronous belt drive mechanism 652, a front right-mounted secondary synchronous belt drive mechanism 653, and a rear right-mounted secondary synchronous belt drive mechanism 654. Compared to the left-mounted camera posture adjustment fixture 3, the right-mounted camera posture adjustment fixture 6 has a similar operating principle and, for the sake of space, will not be further described here.

[0052] In summary, this invention utilizes innovative design to create a highly efficient and accurate product appearance photography inspection system. From product clamping and positioning to multi-angle inspection and orderly transfer, each step has been meticulously designed and optimized, significantly improving inspection efficiency and quality.
