[0002] In modern manufacturing and inspection industries, it is crucial to accurately measure the shape and structural integrity of profiles. Non-contact measurement technology is particularly important when there are many types of profiles, the upper and lower surfaces have different shapes, or even if the shapes are the same, they need to be inspected separately; in the prior art, most roller line equipment can only inspect the upper surface of the profile, while it is more difficult to inspect the bottom. Although some systems can perform bottom inspection, they usually need to adjust the position of the profile, which not only increases the complexity of the inspection process, but also increases the operating cost and time. Therefore, there is an urgent need for a roller line equipment that can measure the bending torsion of the bottom of the profile using a non-contact measurement method without adjusting the position of the profile, so as to improve the inspection efficiency and accuracy, while reducing the difficulty and cost of operation.

[0020] In the description of the present invention, terms such as "up", "down", "left", "right", "inside", and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0021] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] The following examples are given to explain the present invention:

[0023] Example 1: Reference Figure 1 , Figure 1It is a top view of the basic structure of the utility model, including a base 1 and a first slide rail 2, wherein the base 1 includes a support frame 101, a roller 102 and a base plate 103, wherein the bottom surface of the first slide rail 2 is fixed to the upper surface of the base plate 103, so that the base 1 and the first slide rail 2 form an integral structure and are fixed to each other; the support frame 101 is an n-shaped structure, consisting of two vertical frames and a horizontal frame, and the roller 102 is composed of a plurality of rollers 1021 and a roller frame 1023, and the roller frame 1023 and the support frame 101 are connected to each other. The roller 1021 is fixedly connected to the horizontal frame to provide a support structure for part of the roller 1021. The roller 1021 is limited by the limit clamp 1022. The limit clamp 1022 is a structure with a circular through hole inside, which is sleeved on the outer surface of the roller 1021, so that the roller 1021 can rotate axially within the range limited by the limit clamp 1022. This combined structure allows the profile to move horizontally along the rolling direction of the roller 1021. This embodiment also includes a first visual module 2011 and a second visual module 2012, which are fixed at On the sliding base 201, the bottom of the sliding base 201 is slidably connected to the first slide rail 2, so that the first vision module 2011 and the second vision module 2012 can slide synchronously along the first slide rail 2, and both vision modules shoot toward the center position of the upper roller 102 to collect parameter information of the profile on the roller 102; the interior of the vision module includes a camera and a laser transmitter, which cooperate to collect image information and depth information of the profile. The cameras inside the first vision module 2011 and the second vision module 2012 are preferably linear array cameras with a return lens. When active detection is required (that is, the sliding base 201 is required to actively slide back and forth on the first slide rail 2), the first slide rail 2 is configured as an electric or pneumatically powered linear guide. Generally speaking, the guide rail slider can be driven by a ball screw and then by an electric or pneumatically powered power device to make the guide rail slider reciprocate along the linear guide. When used in the present utility model, the guide rail slider is integrated with the sliding base 201.

[0024] Example 2: Reference Figure 2 , Figure 2 2 is a top view of the active roller structure of the utility model. In addition to using all the structures of the first embodiment, it also includes a light source 202 arranged on the sliding base 201. The purpose of setting the light source 202 is to adjust the intensity of the ambient light according to different environments to facilitate the camera to collect information. Figure 3 , Figure 3101 is a top view of the sliding base 201, which also includes a first purge mechanism 20111 and a second purge mechanism 20121, which are respectively used for cleaning the first visual module 2011 and the second visual module 2012. Since the lenses of the first visual module 2011 and the second visual module 2012 are set upward, dust is easily accumulated compared to the traditional top surface detection module. In this case, the first purge mechanism 20111 and the second purge mechanism 20121 can largely ensure the image acquisition effect; the preferred first purge mechanism 20111 and the second purge mechanism 20121 are air pipes connected to a high-pressure air source for ejecting pulsed airflow. Other solutions that can purge airflow can be regarded as alternative solutions and should not be regarded as exceeding the protection scope of the present utility model; in order to ensure the accuracy of the detection, the profile should remain in a neutral position during the detection. As shown in the figure, a plurality of returners 5 are arranged across the upper surface of the support frame 101, with reference to Figure 4 , Figure 4 Schematic diagram of the rear view of the active roller structure of the utility model, showing the left positioning clamp 501 and the right positioning clamp 502 arranged on the inner sides of the left and right sides of the return device 5, both of which include a telescopic member for extending or retracting. Figure 5, the two are movably fixedly connected to the return device 5 through a power cylinder (electric cylinder, air cylinder or hydraulic cylinder, etc.). When the power cylinder is working, the left positioning clamp 501 and the right positioning clamp 502 are pushed out to the center at the same time, which is used to return the profile placed on the roller 102 to the neutral position for easy detection. A laser 503 and a receiver 504 are also arranged on the return device 5. The laser 503 emits a laser which is received and identified by the receiver 504. When the profile passes over the roller 102, the laser emitted by the laser 503 will be blocked to identify the position where the profile passes. A mask 505 is also fixedly arranged on the top of the return device 5. The mask 505 is used to block ambient light and provide a certain dustproof function. A preferred structure is that several return devices 5 are evenly arranged from beginning to end on the upper surface of the support frame 101, and the top masks 505 of several return devices 5 are hinged to the overall structure of the return device 5 to form a gap as a passage. When the top mask 505 is buckled down, it is a compression structure, which can be first The top mask 505 is opened, and a shielding plate or a shielding cloth is used to pass through the mask 505, and then the top mask 505 is buckled down and pressed. The shielding plate or the shielding cloth can be made of a light-transmitting material or a light-shielding material. This structure covers the top of the entire utility model to achieve a dust-proof effect and an optional light-shielding effect. The structure is flexible and detachable. A stopper 6 is also fixedly arranged on the top of one end of the support frame 101. The stopper 6 includes a stopper bracket 601, a stopper beam 602, a baffle 603 and a power cylinder 604. The stopper beam 602 is mounted on the stopper bracket 601, and the bottom of the power cylinder 604 is fixed on the stopper beam 602, and the top movable end is fixed to the baffle 603. Through the above structure, the object to be detected on the roller line of the utility model can leave the utility model or be limited inside the utility model. In a preferred structure, a flexible buffer member is arranged at one end of the baffle to protect the equipment of the utility model and the object to be detected.

[0025] Embodiment 3, in combination with the above two embodiments, this embodiment adds the following content: Figure 2 , Figure 2It also includes a plurality of gears 1024 arranged on the side of any roller 1021. Preferably, the gears 1024 are arranged at intervals to ensure the flexibility of the overall structure. Any gears 1024 are meshed through the connecting belt 1025 to make the plurality of rollers 1021 move in coordination. This design can make the roller 1021 of the utility model rotate actively, and the plurality of actively rotating rollers 1021 can make the profile move on the roller 102. In order to ensure the active rotation of the roller 102, the motor 104 in the figure is also provided. The rotor of the motor 104 is fixedly connected to the motor gear 1041, and the motor gear 1041 is meshed with the connecting belt 1025. When the motor 104 is working, the motor gear 1041 rotates accordingly, and then cooperates with the connecting belt 1025 to rotate in coordination with the plurality of gears 1024. This structure allows the first visual module 2011 and the second visual module 2012 to passively detect the moving profile.
