Description

Technical Field

[0001] This utility model relates to the field of automatic inspection technology for the appearance of electronic products, and more specifically, to an appearance inspection transposition mechanism. Background Technology

[0002] Currently, the appearance inspection of multifaceted products such as precision watch cases and electronic component housings mostly relies on manual labor. Inspectors need to manually rotate the product, and each inspection face takes an average of at least 8 seconds, resulting in an inspection time of more than 30 seconds for a single product housing, which is inefficient. In addition, during the process of touching the product housing, fingerprints and sweat can cause secondary contamination, affecting the product's appearance and reducing the yield rate. Furthermore, the inspection effect varies from person to person, and operators may experience aesthetic fatigue after long-term inspection, which can easily lead to missed or incorrect defects, making it impossible to achieve uniform appearance requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an appearance inspection transposition mechanism to address the above-mentioned defects of the prior art, and to solve the problems of low appearance inspection efficiency, easy secondary pollution and unstable inspection results of polyhedral products.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an appearance inspection and repositioning mechanism, comprising a product control module that controls the rotation of the product to transfer any appearance inspection surface to the photographing position, and a camera detection module that performs photographic inspection on the appearance inspection surface at the photographing position; the product control module includes a product locking unit that positions, fixes, or releases the product from inside, and a rotary motor that drives the product locking unit to rotate intermittently so that multiple appearance inspection surfaces of the product are sequentially repositioned and appear at the photographing position.

[0005] The appearance inspection and repositioning mechanism of this utility model includes a product locking unit comprising a first support frame, on which two clamping arms are provided and a bidirectional drive motor for controlling the two clamping arms to move closer or further apart; the bidirectional drive motor controls the two clamping arms to move toward each other so that the two clamping arms are inserted into the inner cavity of the product, or controls the two clamping arms to move away from each other in the inner cavity so that the two clamping arms respectively engage and abut against two corresponding inner sidewalls of the product.

[0006] The appearance inspection and repositioning mechanism of this utility model includes at least two sets of product locking units. Two adjacent sets of product locking units are connected by a first transmission component, and the frontmost or rearmost product locking unit is connected to the output shaft of the rotary motor by a second transmission component.

[0007] The appearance inspection and repositioning mechanism of this utility model includes a rotating shaft and a fixed seat arranged sequentially on one side of the first support frame; one end of the rotating shaft is fixedly connected to the first support frame, and the other end is rotatably connected to the fixed seat through a rotary bearing; the first transmission component includes two transmission gears respectively fixedly connected to the two rotating shafts, and a synchronous belt connecting the two transmission gears;

[0008] The appearance inspection and repositioning mechanism of this utility model includes a product control module that further includes a mounting slider and a first linear drive module for driving the mounting slider to move closer to or away from the photographing position; the product control module is fixedly mounted on the mounting slider.

[0009] The appearance inspection and repositioning mechanism of this utility model includes two sets of product control modules.

[0010] In the appearance inspection and repositioning mechanism of this utility model, the two sets of product control modules are moved to the photo-taking position in an alternating manner through two first linear drive modules;

[0011] The appearance inspection and repositioning mechanism of this utility model includes a camera inspection module comprising a second support frame and a second linear drive module that drives the second support frame to move linearly closer to or further away from the photographing position; the second support frame is provided with at least one mounting plate, and a CCD inspection camera is provided on the mounting plate; the lens of the CCD inspection camera faces the corresponding photographing position.

[0012] The appearance inspection and repositioning mechanism of this utility model includes a coaxial light source that corresponds to and is coaxial with the CCD inspection camera at one end of the mounting plate facing the imaging position.

[0013] The beneficial effects of this utility model are as follows: This appearance inspection repositioning mechanism has significant advantages over traditional manual inspection methods. Through the coordinated operation of the product locking unit and rotary motor in the product control module, the product rotation can be automatically controlled, accurately transferring any appearance inspection surface to the photographing position, greatly improving inspection efficiency. The inspection time for a single product shell can be significantly shortened, and work efficiency is greatly improved. Simultaneously, the entire inspection process does not require direct human contact with the product shell, effectively avoiding secondary contamination caused by fingerprints, sweat, etc., thus improving product aesthetics and yield. Furthermore, the camera inspection module photographs the appearance inspection surface at the photographing position, resulting in objective and consistent inspection results, unaffected by human factors. This eliminates the problem of missed or incorrect defect detection caused by operator fatigue, ensuring the accuracy and consistency of product appearance inspection. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model provides a preferred embodiment of an appearance inspection and repositioning mechanism. Taking the upper half of a watch casing as an example, it is worth noting that this mechanism is not only applicable to watch casings but can also be applied to other electronic product casings with sidewalls or frames, demonstrating versatility and broad application prospects. Figure 1-3 As shown, the system includes a product control module 10 that controls the rotation of product 02 to switch any of its appearance inspection surfaces to the camera position 01, and a camera inspection module 20 that performs photo inspection on the appearance inspection surfaces at the camera position 01. The product control module 10 includes a product locking unit 11 that positions and releases the product from inside the product, and a rotary motor 12 that drives the product locking unit 11 to rotate intermittently so that multiple appearance inspection surfaces of the product are sequentially moved to the camera position 01. The entire inspection process does not require direct human contact with the product casing, avoiding contaminants such as fingerprints and sweat from human hands from contaminating the product surface, thereby improving the appearance quality and yield of the product, which is especially important for products with extremely high surface requirements, such as precision watch cases.

[0024] This appearance inspection repositioning mechanism offers significant advantages over traditional manual inspection methods. Through the coordinated operation of the product locking unit and rotary motor in the product control module, it automatically controls product rotation, precisely positioning any appearance inspection surface at the photographing position. This greatly improves inspection efficiency, significantly reducing the inspection time for a single product casing and substantially increasing work efficiency. Simultaneously, the entire inspection process eliminates direct human contact with the product casing, effectively preventing secondary contamination caused by fingerprints, sweat, etc., thus enhancing product aesthetics and yield. Furthermore, the camera inspection module photographs the appearance inspection surface at the photographing position, providing objective and consistent results unaffected by human factors. This eliminates the problem of missed or incorrect defects caused by operator fatigue, ensuring the accuracy and consistency of product appearance inspection.

[0025] like Figure 2As shown, in this embodiment, the product locking unit 11 includes a first support frame 111, on which two clamping arms 112 are provided, and a bidirectional drive motor 113 controls the two clamping arms 112 to move closer or further apart. The bidirectional drive motor 113 controls the two clamping arms 112 to move towards each other so that the two clamping arms 112 are inserted into the inner cavity of the product, or controls the two clamping arms 112 to move away from each other in the inner cavity so that the two clamping arms 112 respectively cooperate and abut against the two corresponding inner sidewalls of the product. By inserting the two clamping arms 112 into the inner cavity of the product and cooperating and abutting against the inner sidewalls, not only is scratching or damage to the product appearance that may be caused by traditional clamping methods avoided, especially for precision products with high surface treatment requirements, but the product can also be stably and reliably fixed from the inside. This fixing method can adapt to the inner cavity of products of different sizes and shapes, ensuring that the product will not shake or shift during rotation, thereby ensuring the accuracy and repeatability of the detection.

[0026] In this embodiment, at least two sets of product locking units 11 are provided. Two or more sets of product locking units 11 are arranged side by side, which can simultaneously photograph and inspect the appearance of multiple products, further improving the inspection efficiency. Adjacent sets of product locking units 11 are connected by a first transmission component 13. The frontmost or rearmost product locking unit 11 is connected to the output shaft of the rotary motor 12 by a second transmission component 14. Multiple product locking units 11 are connected by multiple transmission components. The power of a single rotary motor 12 can be transmitted to each product locking unit 11 sequentially through multiple transmission components, ensuring that each product locking unit can operate synchronously and in a coordinated manner, thereby achieving smooth rotation of the product.

[0027] Furthermore, a rotating shaft 114 and a fixed seat 115 are sequentially arranged on one side of the first support frame 111; one end of the rotating shaft 114 is fixedly connected to the first support frame 111, and the other end is rotatably connected to the fixed seat 115 through a rotary bearing 116; the first transmission assembly 13 includes two transmission gears 131 respectively fixedly connected to the two rotating shafts 114, and a synchronous belt 132 connecting the two transmission gears 131. The synchronous belt 132 meshes with the two transmission gears 131 respectively for transmission. In this embodiment, the structure of the second transmission assembly 14 is the same as that of the first transmission assembly 13. One transmission gear 131 of the second transmission assembly 14 is fixedly connected to the rotating shaft on the frontmost or rearmost product locking unit 11, and the other transmission gear 131 is fixedly connected to the output shaft of the rotary motor 12; during the start-up and rotation of the rotary motor 12, the rotating shaft of the first support frame 111 connected to it is driven to rotate through the second transmission assembly 14, and the rotating shaft of the first support frame 111 drives the adjacent product locking unit 11 to rotate through the first transmission assembly 13. In this embodiment, the rotary motor 12 can precisely control the rotation angle and position of each product locking unit 11. By using the existing programmable motor control, the specific inspection surface of the product can be accurately moved to the preset photo position 01, which improves the accuracy and repeatability of the inspection. It realizes a smooth, synchronous, and reliable transmission of rotational power between the product locking units, ensuring the accurate repositioning and stable support of the product during the inspection process. This is a key guarantee for the efficient and reliable operation of the entire appearance inspection and repositioning mechanism.

[0028] Furthermore, the product control module 10 also includes a mounting slider 15 and a first linear drive module 16 for driving the mounting slider 15 to move closer to or away from the photographing position 01. In this embodiment, the first linear drive module 16 can be implemented using a linear drive motor or a linear screw motor module in the prior art. The product control module 10 is fixedly mounted on the mounting slider 15. The two ends of the first linear drive module 16 are respectively provided with product loading / unloading positions and the photographing position 01. The mounting slider 15 can move along the guide rail direction under the drive of the first linear drive module 16, thereby driving the product control module 10 (and the product 02 fixed on it) to move between the product loading / unloading positions and the photographing position 01.

[0029] In one embodiment, such as Figure 1As shown, the product control module 10 can also be configured with two sets; the two sets of product control modules 10 are moved alternately to the photo-taking position 01 via two first linear drive modules 16. By setting two sets of product control modules 10, while one set is performing product inspection, the other set is performing product loading and preparation. After one set completes inspection, the two sets can move alternately, sending the prepared product to the photo-taking position 01 for inspection, while the other set loads the next product or replaces a product. This staggered operation method can significantly shorten the inspection cycle of multiple products, make full use of equipment resources, and improve overall inspection efficiency.

[0030] In this embodiment, as Figure 3 As shown, the camera detection module 20 includes a second support frame 21 and a second linear drive module 22 that drives the second support frame 21 to move linearly closer to or away from the shooting position 01. In this embodiment, the moving direction of the second linear drive module 22 is perpendicular to the moving direction of the first linear drive module 16. The second support frame 21 is provided with at least one mounting plate 23, and a CCD detection camera 24 is mounted on the mounting plate 23. The mounting plate 23 provides a stable support platform for the CCD detection camera 24, ensuring that the camera remains stable during movement and shooting. The lens of the CCD detection camera 24 faces the corresponding shooting position 01. In this embodiment, the CCD detection camera 24 and the corresponding shooting position are on the same straight line. Through the second linear drive module 22, the second support frame 21 and the CCD detection camera 24 mounted on it can be driven to move closer to or away from the shooting position 01 in a straight line. This flexibility in position adjustment allows the camera to make precise adjustments to the focal length for products of different sizes, ensuring the acquisition of clear, high-quality images. For larger products, the camera can be moved away from the shooting position to obtain a wider field of view; for smaller products, the camera can be moved closer to the shooting position to improve image resolution and detail capture capabilities. The second linear drive module 22 can be implemented using either a linear drive motor or a linear lead screw motor module from existing technologies.

[0031] To further enhance illumination for various product surfaces, a coaxial light source 25, corresponding to and coaxial with the CCD inspection camera 24, is fixedly mounted on the end of the mounting plate 23 facing the imaging position 01. This provides uniform, shadow-free illumination, highlights surface details, improves image contrast, reduces reflection interference, simplifies the optical system, and enhances inspection efficiency and adaptability.

[0032] The operating principle of the appearance inspection transposition mechanism is as follows (single module mode):

[0033] 1. In the initial state, the first linear drive module 16 drives the product control module 10 to move to the product loading and unloading position, and the two clamping arms of the product locking unit 11 are inserted into the product and are connected and fixed to the corresponding two inner side walls.

[0034] 2. The first linear drive module 16 drives the product locking unit 11 and its fixed product to move to the photo-taking position; the rotary motor drives the product locking unit and its fixed product to rotate and sequentially transfer the four appearance detection surfaces on the outer surface of the product to the photo-taking position 01. At the same time, the second linear drive module 22 on the side drives the CCD detection camera to move to the appropriate position and sequentially takes pictures of the four appearance detection surfaces on the side of the product at the photo-taking position to detect its appearance.

[0035] 3. Subsequent actions are repeated in a loop.

[0036] Similarly, when the product control module 10, product locking unit 11, image capture position 01, and CCD inspection camera 24 are each equipped with two or more sets, the operating principle of the appearance inspection and repositioning mechanism is as follows (taking two sets as an example):

[0037] 1. In the initial state, both first linear drive modules 16 drive the product control module 10 to move to the product loading and unloading position, and the two product locking units 11 on the product control module 10 fix and position the product from the inside.

[0038] 2. The two first linear drive modules 16 alternately drive the two product locking units 11 and their fixed products to move to two photo-taking positions (for example, the first linear drive module on one product control module 10 drives the two product locking units 11 and their fixed products to move to the photo-taking position to prepare for photo-taking and detection, while the first linear drive module on the other product control module 10 drives the two product locking units 11 and their fixed products to move to the product loading and unloading position to prepare for material replacement); the rotary motor drives the products on the two product locking units 11 to rotate simultaneously through the first transmission component and the second transmission component, thereby sequentially transferring the four appearance detection surfaces on the outer surfaces of the two products to the corresponding photo-taking positions 01, while the two CCD detection cameras on the side sequentially take photos of the four appearance detection surfaces on the side of the products at the two photo-taking positions to detect their appearance.

[0039] 3. Subsequent actions are repeated in a loop.

[0040] Through the above solution, this invention can improve the efficiency of product appearance inspection and solve the problems of labor costs associated with manual inspection. With this mechanism, the inspection process of the outer casing of a product can be more efficient and accurate, improving production efficiency and ensuring product quality.

[0041] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
