Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0017] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0018] When inspecting the mounted materials, a single carrier is used to transfer the mounted materials to the vision inspection position in sequence. The materials need to be flipped over, and it is impossible to inspect both the top and bottom sides of the materials at the same time. This results in low product inspection efficiency. When facing large-scale production, the transfer cycle is long, which makes it difficult to meet the needs of high-efficiency production.

[0019] In view of this, the present invention provides a detection displacement carrier module driven by dual linear motors. Through the cooperation of linear motors, connecting frames, support frames, carrier modules, detection modules, and displacement sensing modules, a dual linear motor and dual carrier platform design is adopted. The carrier platform uses a combination of vacuum adsorption and groove limiting to stably support and adsorb the mounted materials. By translating the carrier platform, the two sets of materials are alternately transferred to the detection position, improving the material transfer efficiency. Furthermore, a binocular vision system is adopted, which simultaneously acquires images of the top and bottom surfaces of the steel material moved to the detection position through two cameras. Synchronous detection of the top and bottom surfaces can be achieved without flipping the materials, improving the product detection efficiency, effectively shortening the transfer cycle, and meeting the needs of high-efficiency production.

[0020] Depend on Figure 1-6 As can be seen, the detection displacement carrier module driven by dual linear motors in this case includes two linear motors 1. The output end of the linear motor 1 is fixedly connected to a connecting frame 2. A support frame 3 is set above the two linear motors 1. The detection displacement carrier module driven by dual linear motors also includes a carrier module 4, a detection module 5, and a displacement sensing module 6. The carrier module 4 is set on the top of the connecting frame 2; the detection module 5 is set on the top of the support frame 3; and the displacement sensing module 6 is set on one side of the top of the support frame 3. The carrier module 4 adsorbs and fixes the bonded steel material, making it move accurately to the detection position. The detection module 5 detects the steel material that has moved to the detection position to determine whether its bonding quality meets the standard. The displacement sensing module 6 senses the movement displacement of the carrier module 4 in real time.

[0021] In the specific implementation process, it is worth noting that through the cooperation between linear motor 1, connecting frame 2, and carrier module 4, carrier module 4 is installed on the top of the output end of linear motor 1 via connecting frame 2. Carrier module 4 uses a combination of vacuum adsorption and groove limiting to stably support and adsorb the applied material. By controlling linear motor 1, carrier module 4 can be driven to move precisely linearly, quickly and accurately transferring the applied material to the detection position. Furthermore, two linear motors 1 drive two carrier modules 4 to perform independent movement operations, with one carrier module... When module 4 is loading materials for visual inspection, another carrier module 4 is positioned at the material loading / unloading point, allowing the two sets of materials to be alternately transferred to the inspection position. This improves material transfer efficiency, effectively shortens the transfer cycle, and meets the demands of high-efficiency production. Through the coordination of linear motor 1, connecting frame 2, support frame 3, carrier module 4, and inspection module 5, the inspection module 5 employs a binocular vision system. Two cameras simultaneously capture images of the top and bottom surfaces of the steel material moving to the inspection position and transmit the captured information to the visual inspection processing system. The visual inspection processing system then determines the material's quality based on the image information. For optimal fit, simultaneous detection of both top and bottom surfaces can be achieved without flipping the material, improving product detection efficiency. The displacement sensing module 6 accurately measures and provides real-time feedback on the movement of the carrier module 4, facilitating precise control of the linear motor 1 by the control system. This ensures the carrier module 4 accurately moves the material to the detection and initial positions, improving system positioning accuracy and operational stability. Through the cooperation of the linear motor 1, connecting frame 2, support frame 3, carrier module 4, detection module 5, and displacement sensing module 6, a dual linear motor 1 and dual carrier platform design is adopted. The carrier platform uses... The combination of vacuum adsorption and groove limiting provides stable support and adsorption for the mounted materials. By translating the carrier platform, the two sets of materials are alternately transferred to the detection position, improving the material transfer efficiency. Furthermore, a binocular vision system is used to simultaneously capture images of the top and bottom surfaces of the steel material moving to the detection position through two cameras. This allows for synchronous detection of both sides without flipping the material, improving product detection efficiency, effectively shortening the transfer cycle, and meeting the needs of high-efficiency production. The specific model of the linear motor 1 is not limited, as long as it meets the usage requirements.

[0022] In one feasible embodiment, the carrier module 4 includes a movable stage 41, a platform 42, detection holes 43, a moving module 44, and a positioning module 45. The movable stage 41 is disposed above the connecting frame 2; the platform 42 is fixedly connected to the top of the movable stage 41; multiple detection holes 43 are provided, equidistantly disposed on both sides of the movable stage 41 and the platform 42; the moving module 44 is disposed at the bottom of the movable stage 41; and the positioning module 45 is disposed at the top of the platform 42. The platform 42 supports and fixes the mounted material through the positioning module 45, and the moving module 44 drives the movable stage 41 to move precisely, so that the material can accurately reach the detection position. The detection holes 43 facilitate the detection of the bottom surface of the material by the detection equipment below.

[0023] In the specific implementation process, it is worth noting that, through the cooperation between the connecting frame 2, the moving stage 41, the platform 42, and the detection holes 43, according to the detection requirements, multiple detection holes 43 are opened inside the moving stage 41 and the platform 42 to form a hollow structure. This ensures stable support for the material while allowing the detection equipment below to collect images of the bottom surface of the material through the detection holes 43, thereby simultaneously detecting both the top and bottom surfaces of the material. This reduces the need for material flipping operations and improves the material detection efficiency. The moving module 44 is used to move the platform 42 horizontally when the moving stage 41 and the platform 42 move to the detection position, so that the moving stage 41, the platform 42, and the material to be detected move to the detection position for image acquisition. The positioning module 45 is used to limit and fix the material after it is mounted, improving the stability of the material during transportation and detection.

[0024] In one feasible embodiment, the moving module 44 includes a slide rail 441, a slider 442, and a servo cylinder 443. Two slide rails 441 are provided and fixedly connected to the top two sides of the connecting frame 2. Two sliders 442 are provided and fixedly connected to the bottom two sides of the moving stage 41, and slidably connected to the outer wall of the slide rail 441. The servo cylinder 443 is fixedly connected to the top of the connecting frame 2 on the side away from the detection module 5, and its output end is fixedly connected to the bottom of the moving stage 41. The slide rail 441 and the slider 442 enable the moving stage 41 to slide smoothly along a predetermined track, and the servo cylinder 443 provides power support for the movement of the moving stage 41, moving the mounted material into or out of the detection position.

[0025] In the specific implementation process, it is worth noting that through the cooperation between the connecting frame 2, the moving stage 41, the slide rail 441, the slider 442, and the servo cylinder 443, after the linear motor 1 moves the material to the designated position, the control system automatically controls the servo cylinder 443 to move the moving stage 41 from the top of the connecting frame 2 to the detection position for image acquisition. After the detection is completed, the control system automatically controls the servo cylinder 443 to move the moving stage 41 from the detection position back to the initial position, and then moves the material to the loading and unloading position for material replacement. This avoids interference between the two sets of displacement carriers during the detection and loading and unloading process, and improves the continuity and efficiency of the overall production process. The specific model of the servo cylinder 443 is not limited, as long as it meets the usage requirements.

[0026] In one feasible embodiment, the positioning module 45 includes a positioning groove 451, an adsorption hole 452, and a connection port 453. The positioning groove 451 is located on both sides of the top of the stage 42. Multiple adsorption holes 452 are provided and are equidistantly located inside the positioning groove 451. The connection port 453 is located on the side of the moving stage 41 away from the detection module 5 and is connected to the adsorption hole 452. The positioning groove 451 limits the placement of the material at the top of the stage 42, and by connecting the connection port 453 to an external vacuum device, a negative pressure is generated in the adsorption hole 452, and the material is fixed in the positioning groove 451 by vacuum adsorption.

[0027] In the specific implementation process, it is worth noting that through the cooperation between the stage 42, the positioning groove 451, the adsorption hole 452, and the connection port 453, the connection port 453 is connected to the external vacuum equipment. After the material after mounting is placed into the positioning groove 451, the positioning groove 451 limits it. At the same time, the external vacuum equipment is activated, and the negative pressure is generated in the adsorption hole 452 through the connection port 453, which tightly adsorbs the material in the positioning groove 451, ensuring that the material will not be displaced or fall off during transportation and testing, thereby improving the accuracy and stability of material testing. The combination of vacuum adsorption and groove limiting not only ensures the stable bearing of the material, but also avoids the damage that traditional mechanical clamps may cause to the material, further improving the practicality and reliability of the detection displacement carrier module.

[0028] In one feasible embodiment, the detection module 5 includes a mounting frame 51, a visual acquisition camera 52, and a coaxial light source 53. Two mounting frames 51 are provided, positioned one above the other on the side where the two linear motors 1 are close to each other, with the upper mounting frame 51 fixedly connected to the top of the support frame 3. The visual acquisition camera 52 is located on one side of the outer wall of the mounting frame 51, and the two visual acquisition cameras 52 are positioned correspondingly. The coaxial light source 53 is located on the side where the two visual acquisition cameras 52 are close to each other. The two visual acquisition cameras 52 constitute a binocular vision system, which simultaneously acquires images of the top and bottom surfaces of the steel material that has moved to the detection position. The coaxial light source 53 provides a uniform and shadowless lighting environment for the visual acquisition cameras 52.

[0029] In the specific implementation process, it is worth noting that through the cooperation between the support frame 3, the fixing frame 51, the visual acquisition camera 52, and the coaxial light source 53, the upper visual acquisition camera 52 is fixed to the top of the support frame 3 by the fixing frame 51, and the lower visual acquisition camera 52 is fixed to the equipment frame or base plate by the fixing frame 51. The lens axes of the two cameras coincide and face the detection position, so that the detection module 5 can achieve synchronous high-quality image acquisition from both the upper and lower surfaces without flipping the material, thereby improving detection efficiency and accuracy. The light emitted by the coaxial light source 53 is coaxial with the camera axis, effectively eliminating shadows and reflections, and providing a clear and stable image environment for visual acquisition. The specific models of the visual acquisition camera 52 and the coaxial light source 53 are not limited, as long as they meet the usage requirements.

[0030] In one feasible embodiment, the displacement sensing module 6 includes a mounting bracket 61, a laser rangefinder 62, and a reset sensing module 63. The mounting bracket 61 is fixedly connected to the top side of the support frame 3; the laser rangefinder 62 is fixedly connected to the end of the mounting bracket 61 away from the support frame 3 and is connected to the platform 42; the reset sensing module 63 is located on the outside of the end of the linear motor 1 away from the laser rangefinder 62. The laser rangefinder 62 is mounted above the detection position via the mounting bracket 61 to sense the movement displacement of the platform 42 in real time, so that the material moves accurately to the predetermined position. The reset sensing module 63 accurately senses the initial position of the material loading when the linear motor 1 performs a reset action.

[0031] In the specific implementation process, it is worth noting that the laser rangefinder 62 is mounted on the top side of the support frame 3 via the mounting bracket 61. By emitting a laser beam downwards and receiving the reflected laser, the measurement value of the laser rangefinder 62 will change accordingly after the platform 42 moves to the detection position, and is transmitted to the control system in real time. The control system uses this information to precisely control the operation of the linear motor 1 to ensure that the platform 42 stops accurately at the detection position, thereby achieving precise positioning of the material during the detection process. The reset sensing module 63 is used to sense the carrier at the initial position of the material loading so that the control system can control the linear motor 1 according to the sensing signal. The specific model of the laser rangefinder 62 is not limited, as long as it meets the usage requirements.

[0032] In one feasible embodiment, the reset sensing module 63 includes a mounting slot 631, a connector 632, and a photoelectric sensor 633. The mounting slot 631 is disposed on the side of the linear motor 1; the connector 632 is disposed at the end of the linear motor 1 away from the detection module 5 and is connected to the inner wall of the mounting slot 631; the photoelectric sensor 633 is fixedly connected to the outer wall of the connector 632 and is connected to the connector 2. The connector 632 is fixed to the end of the linear motor 1 away from the detection module 5 through the mounting slot 631, and the photoelectric sensor 633 accurately senses the initial position of the connector 2 to perform loading or unloading operations on the mounting material.

[0033] In the specific implementation process, it is worth noting that through the cooperation between the linear motor 1, the mounting slot 631, the connecting seat 632, and the photoelectric sensor 633, the photoelectric sensor 633 is fixed to the mounting slot 631 via the connecting seat 632. It senses the carrier at the initial position of material loading. After the output end of the linear motor 1 drives the carrier module 4 to move to the material loading position, the photoelectric sensor 633 detects the position change of the carrier module 4 and quickly transmits this signal to the control system. After receiving the signal, the control system automatically controls the linear motor 1 to stop running, so that the platform 42 stops precisely at the material loading position for material loading or unloading operations. The specific model of the photoelectric sensor 633 is not limited, as long as it meets the usage requirements.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
