[0077] The core of the utility model is to provide a detection system to improve detection efficiency and avoid the influence of the detection environment on operators.

[0078] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0079] like Figure 1 As shown, an embodiment of the utility model discloses a detection system, which can be used to detect a product 600, and no operator participation is required during the detection process. Automatic loading, station switching, detection and unloading can be completed, and the detection efficiency is high.

[0080] The detection system disclosed in the specific embodiment of the utility model includes a station conversion module 500, a material loading and receiving module 100, a detection module and a material unloading module 400. Among them, the station conversion module 500 has a product clamping area corresponding to each station, and can drive each product clamping area to switch between each station. The number of product clamping areas corresponds to the number of stations, and the station conversion module 500 completes a station switching once it moves. Taking the four stations ABCD as an example, the station conversion module 500 needs to set four product clamping areas abcd. Taking the example that when the work station conversion module 500 is in the initial state, the product clamping area a corresponds to the work station A, the product clamping area b corresponds to the work station B, the product clamping area c corresponds to the work station C, and the product clamping area d corresponds to the work station D, then the work station conversion module 500 rotates once, and the product clamping area a corresponds to the work station B, the product clamping area b corresponds to the work station C, the product clamping area c corresponds to the work station D, and the product clamping area d corresponds to the work station A, and so on, until the product clamping area a corresponds to the work station A, the product clamping area b corresponds to the work station B, the product clamping area c corresponds to the work station C, and the product clamping area d corresponds to the work station D, and one detection cycle is completed.

[0081] The loading and receiving module 100 is set at the loading station, and is used to receive the product 600 to be tested, and transport the product 600 to be tested to the product clamping area at the loading station. The loading and receiving module 100 needs to receive the product 600 to be tested from the upstream equipment, and transport the product 600 to the product clamping area at the loading station. The station conversion module 500 transports the product 600 in the product clamping area from the loading station to the next station.

[0082] The detection module is arranged at the detection station to detect the product to be detected in the product clamping area at the detection station. The specific detection principle of the detection module should be determined in combination with the parameters of the product 600 to be detected, so as to complete the corresponding detection of the product 600.

[0083] The unloading module 400 is arranged at the unloading station, and is used to take out the product 600 on the product clamping area at the unloading station from the product clamping area. It should be noted that the unloading station should be located downstream of the inspection station, so that the inspected product 600 can be taken out through the unloading module 400, so that the product clamping area corresponding to the unloading station is emptied, so that the emptied product clamping area can be transported to the loading station, and the product to be inspected can be clamped on the emptied product clamping area through the loading and receiving module 100.

[0084] In summary, the utility model can realize automatic loading, testing, unloading and other working cycles. Compared with manual testing, it improves the testing efficiency and does not require the participation of operators. Even if harmful substances exist in the testing environment, it will not affect the health of the operator. Therefore, it can adapt to testing in various environments.

[0085] like Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, the workstation conversion module 500 includes a rotation drive device 501, a turntable 502 and a positioning device. The rotation drive device 501 can be a direct drive motor or other drive devices as long as it can output rotational power.

[0086] The turntable 502 is connected to the output end of the rotary drive device 501, and the product clamping area is set on the turntable 502. Specifically, each product clamping area is symmetrically arranged along the center of the output end of the rotary drive device 501. Taking four product clamping areas as an example, the rotary drive device 501 drives the turntable 502 to rotate 90 degrees each time, and then one station switching can be realized.

[0087] Each product clamping area is provided with a positioning device for positioning the product 600 , and the positioning device is used to position the product 600 to prevent the product 600 on the product clamping area from changing position or falling during the operation of the rotary drive device 501 .

[0088] In order to facilitate the arrangement of the positioning device on the turntable 502, in this embodiment, the turntable 502 may be provided with a limiting groove in the product clamping area, and the positioning clamping plate of the positioning device may be arranged in the limiting groove. Specifically, the positioning device may include a first positioning clamping plate 505, a second positioning clamping plate 506, a first positioning drive device 503 and a second positioning drive device 504.

[0089] The first positioning clamp plate 505 and the second positioning clamp plate 506 are both slidably matched in the limiting groove, and the first positioning clamp plate 505 and the second positioning clamp plate 506 are used to clamp the product 600. A corresponding slide rail 507 can be provided in the limiting groove, and the first positioning clamp plate 505 and the second positioning clamp plate 506 are slidably matched with the slide rail 507, and the sliding direction of the first positioning clamp plate 505 and the second positioning clamp plate 506 is constrained by the slide rail 507 to prevent the first positioning clamp plate 505 and the second positioning clamp plate 506 from being stuck due to deflection when sliding.

[0090] In order to facilitate the clamping of product 600, Figure 6 As shown, a first clamping notch 5051 is provided on one side of the first positioning clamping plate 505 facing the second positioning clamping plate 506, and a second clamping notch 5061 corresponding to the first clamping notch 5051 is provided on one side of the second positioning clamping plate 506 facing the first positioning clamping plate 505. The first clamping notch 5051 and the second clamping notch 5061 are clamped on both sides of the product 600, and the contours of the first clamping notch 5051 and the second clamping notch 5061 can be designed according to the outer contour of the product 600, so that the outer surface of the product 600 can be clamped without wearing the product 600.

[0091] Furthermore, the shapes of the first clamping notch groove 5051 and the second clamping notch groove 5061 can be designed to be the same and symmetrically arranged; in the direction from the opening side to the bottom side of the groove, the width of the first clamping notch groove 5051 and the second clamping notch groove 5061 gradually decreases. In this embodiment, the first clamping notch groove 5051 and the second clamping notch groove 5061 are designed as a flared structure, which can adapt to the positioning of products 600 of various sizes. It should be noted that the width of the opening end of the first clamping notch groove 5051 and the second clamping notch groove 5061 should be smaller than the diameter of the product 600.

[0092] Figure 6 In the illustrated solution, the first positioning clamping plate 505 has eight first clamping notch grooves 5051, and the second positioning clamping plate 506 has eight second clamping notch grooves 5061. The first positioning clamping plate 505 and the second positioning clamping plate 506 can clamp eight products 600 at a time. It should be noted that the number of the first clamping notch grooves 5051 and the second clamping notch grooves 5061 is not limited to eight, and can be designed according to actual needs.

[0093] The output end of the first positioning drive device 503 is connected to the first positioning clamping plate 505, and the output end of the second positioning drive device 504 is connected to the second positioning clamping plate 506, so as to drive the first positioning clamping plate 505 and the second positioning clamping plate 506 to switch between the clamping position and the unloading position. In this embodiment, the second positioning drive device 504 is an electric displacement table, and the first positioning clamping plate 505 is a cylinder. It should be noted that the first positioning drive device 503 and the second positioning drive device 504 can also be other drives as long as they can output linear motion.

[0094] When the product 600 is placed between the first clamping notch 5051 and the second clamping notch 5061 by the feeding and receiving module 100, the first positioning drive device 503 and the second positioning drive device 504 respectively drive the first positioning clamp plate 505 and the second positioning clamp plate 506 to approach each other, and then clamp the product 600 between the first clamping notch 5051 and the second clamping notch 5061. Due to the different diameters of the products 600, it is necessary to control the clamping distances of the first positioning clamp plate 505 and the second positioning clamp plate 506 to be different, so as to achieve the positioning of products 600 of different sizes. In this embodiment, the second positioning drive device 504 is designed as an electric displacement table, through which different points of the products 600 of different models and different outer diameters can be fixed, so as to achieve safe loading of the products 600 without collision or scratching.

[0095] like Figure 3 and Figure 4 As shown, in a specific embodiment of the utility model, the material loading and receiving module 100 includes a material loading and lifting drive device 103 and a material receiving and positioning component. Among them, the material receiving and positioning component is connected to the output end of the material loading and lifting drive device 103, and is used to position the product 600 to be detected. The shape of the material receiving and positioning component can be designed to match the product 600 to be positioned, so as to facilitate the positioning of the product 600 on the material receiving and positioning component. The material loading and lifting drive device 103 is used to drive the material receiving and positioning component to perform lifting and lowering movements, so that when the material receiving and positioning component is driven to descend, the product 600 on the material receiving and positioning component can be dropped between the first positioning clamping plate 505 and the second positioning clamping plate 506. The material loading and lifting drive device 103 can be an electric cylinder or other driving device, as long as it can drive the material receiving and positioning component to perform lifting and lowering movements. The electric cylinder can be fixed at different points according to products of different models and different heights, so as to achieve safe loading of products without collision or scratching.

[0096] The loading lifting drive device 103 can be fixed on the side hanging plate 101, and a flat mounting plate 102 is fixed on the side hanging plate 101. The flat mounting plate 102 can be fixed on the mounting base of the workstation to realize the installation of the loading lifting drive device 103. It should be noted that the rotation drive device 501 can also be installed on the mounting base.

[0097] Furthermore, the material receiving and positioning assembly may include a positioning connection portion 104 and a material receiving portion 105. The positioning connection portion 104 is connected to the output end of the material feeding and lifting drive device 103, and the positioning connection portion 104 serves as the installation base of the material receiving portion 105. There are multiple material receiving portions 105, and they are all arranged on the positioning connection portion 104. The top 1051 of the material receiving portion 105 is used to position the product 600 to be tested, and the product clamping area is provided with a through hole 508 (such as Figure 6 As shown in the figure, when receiving the material, the top of the receiving portion 105 is located above the positioning device, and when dropping the material, the top of the receiving portion 105 is located below the positioning device.

[0098] Before the material receiving module 100 receives the material, the material receiving and positioning assembly 103 is driven by the material loading and lifting drive device 103 to rise to the material receiving position, that is, the top of the material receiving portion 105 is located above the positioning device. After the product 600 to be inspected conveyed from the upstream equipment is positioned at the top of the material receiving portion 105, the material loading and lifting drive device 103 drives the material receiving portion 105 and the product 600 thereon to descend. When the product 600 descends to between the first positioning clamping plate 505 and the second positioning clamping plate 506, the product 600 is stopped by the turntable 502 between the first positioning clamping plate 505 and the second positioning clamping plate 506, and then the first positioning clamping plate 505 and the second positioning clamping plate 506 are driven closer to each other by the first positioning drive device 503 and the second positioning drive device 504 respectively, and then the product 600 is clamped between the first clamping notch groove 5051 and the second clamping notch groove 5061.

[0099] Furthermore, the material receiving and positioning assembly may further include a material receiving detection device 106 disposed on the material receiving portion 105. The material receiving detection device 106 may be an optical fiber sensor. The material receiving detection device 106 is used to detect whether there is a product 600 to be detected on the top of the material receiving portion 105. After the material receiving detection device 106 detects the product 600, the descending action is performed.

[0100] like Figure 7 As shown, in this embodiment, the detection module may include a first visual detection module 200 and a second visual detection module 300. Two visual detection modules are provided to respectively perform photographic detection on different defects of the product 600.

[0101] The first visual inspection module 200 and the second visual inspection module 300 are arranged at two adjacent workstations. Taking the first visual inspection module 200 arranged upstream of the second visual inspection module 300 as an example, after the product 600 is inspected by the first visual inspection module 200, it is transported one workstation downstream to be inspected by the second visual inspection module 300.

Among them, the first mounting seat 201 is the installation base for other components of the first visual inspection module 200. The first linear displacement device 202 is arranged on the first mounting seat 201 and extends along the first direction. The first direction is the arrangement direction of the products on the product clamping area on the station where the first visual inspection module 200 is located. The first camera assembly is driven by the first linear displacement device 202 to reciprocate along the first direction. Specifically, the first camera assembly can cooperate with the first linear displacement device 202 through the first displacement platform 203 to realize the movement of the first camera assembly along the first direction, so as to realize the sequential photography and inspection of each product 600 arranged along the first direction.

[0103] Furthermore, the first camera assembly includes a first area array camera 204, a first telescopic lens 205, an annular coaxial light source 206, and a first strip light source 207. The first area array camera 204 is fixed to the first translation stage 203, the first telescopic lens 205 is connected to the imaging end of the first area array camera 204, the first strip light source 207 is arranged outside the first telescopic lens 205, and the annular coaxial light source 206 is arranged in the area surrounded by the first strip light source 207. The first area array camera 204 is used to detect the external surface of the product, and the combined line light is obtained by the annular light emitted by the annular coaxial light source 206 and the strip light emitted by the first strip light source 207, so that the first area array camera 204 can obtain a clearer image.

[0104] It should be noted that image processing detection technology is a technology commonly used in the prior art. The focus of this application is not to disclose an image processing detection technology that is different from the prior art, but is only based on the application of high-resolution area array cameras and image processing detection technology.

The second direction is the arrangement direction of the products on the product clamping area on the station where the second visual inspection module 300 is located. The second camera assembly is driven by the second linear displacement device 302 to reciprocate along the second direction. Specifically, the second camera assembly can cooperate with the second linear displacement device 302 through the second displacement stage 303 to realize the movement of the second camera assembly along the second direction, so as to realize the sequential photography and detection of each product 600 arranged along the second direction.
