Description

Technical Field

[0001] This utility model relates to the field of size detection technology, specifically to a visual size measurement device. Background Technology

[0002] With the development of industrial automation and intelligent manufacturing, machine vision measurement technology has been widely used in various fields such as product dimension inspection, defect identification, and position determination. Existing machine vision dimension measurement devices typically adopt a fixed structure, with the measuring camera vertically positioned directly above the product to be measured. Dimensional data is acquired by collecting and processing images of the product's upper surface.

[0003] For example, Chinese patent application number CN202323199143.3 discloses a vision-based dimensional measurement device. This device uses a rotating shaft to drive a pulley, causing a conveyor belt to move and transport the object to be measured to a position below an industrial camera, which then measures the object's dimensions. The device also includes a light source installed below the camera to improve image clarity and measurement accuracy.

[0004] Although the above technologies can effectively measure the dimensions of the product's upper surface, the fixed camera position only allows for the acquisition of a top-view image of the product. The side structure of the product cannot be acquired simultaneously, and manual rotation or adjustment of the product's posture is still required to complete multi-faceted measurements, resulting in low inspection efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a visual size measurement device to solve the problem that the existing size measurement devices can only capture the top view image of the product due to the fixed position of the camera. The side structure of the product cannot be captured at the same time, and the product still needs to be manually flipped or the posture of the product to complete the multi-face measurement, resulting in low detection efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A visual size measuring device, comprising: The base is equipped with a worktable for placing items to be inspected. The mounting bracket is arranged in an arc shape on the base and has several slots. The detection base is equipped with a detection camera and is slidably connected to the mounting frame. The detection base is also slidably provided with a locking device. When the locking device is engaged with one of the slots, it can fix the detection base after it slides along the extension direction of the mounting frame.

[0007] Compared with the prior art, the present invention has the following beneficial effects: 1. By sliding the detection seat onto the arc-shaped mounting frame and setting several slots on the mounting frame for positioning with the locking mechanism, the detection camera can move along the arc path and acquire images at different angles, thereby realizing the size detection of multiple sides of the object to be measured. This avoids the tedious operation of manually flipping the product and significantly improves the measurement efficiency and automation level.

[0008] Furthermore, the locking component includes a movable plate that is slidably engaged with the detection seat. The movable plate is provided with a locking block. The movable plate is also provided with a connecting rod. The connecting rod passes through the detection seat and is fitted with a spring. The spring abuts against the detection seat and the movable plate.

[0009] Furthermore, the movable plate has auxiliary blocks extending vertically.

[0010] Furthermore, the detection seat is provided with a sliding groove, and the movable plate is provided with a limiting block, which is engaged in the sliding groove.

[0011] Furthermore, the connecting rods are configured as two, symmetrically distributed on the movable plate.

[0012] Furthermore, the mounting bracket is provided with a track groove along its extension direction, and the detection seat is provided with a pulley assembly, which rolls and fits against the track groove and can slide along the extension direction of the track groove.

[0013] Furthermore, the detection seat is provided with a mounting ring, the mounting ring forming a mounting cavity, the detection camera is mounted in the mounting cavity, and a bolt is provided on the outside of the mounting ring, penetrating into the mounting cavity, the bolt being connected to the detection camera.

[0014] Furthermore, the worktable is rotatably mounted on the base. Attached Figure Description

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0018] In the description of this utility model, it should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0019] like Figure 1-3 As shown in the figure, this utility model embodiment proposes a visual size measuring device, including: a base 10, with a worktable 11 for placing the item to be inspected; a mounting frame 20, which is arc-shaped and disposed on the base 10, and is provided with a plurality of slots 21; a detection seat 30, on which a detection camera 31 is mounted and slidably connected to the mounting frame 20, and the detection seat 30 is slidably provided with a locking member 40, which can be engaged with one of the slots 21 to fix the detection seat 30 after it slides along the extension direction of the mounting frame 20. It should be understood that the detection camera 31 is a conventional device in the art, and since this utility model does not make any improvements to it, its specific structure and working method will not be described in detail here.

[0020] In this embodiment of the invention, when performing product size inspection, the operator first places the item to be inspected on the workbench 11 on the base 10, and slides the inspection seat 30 to a suitable inspection position on the mounting frame 20 according to the inspection requirements. For example, when performing traditional vertical measurements, the inspection seat 30 can be moved to the central axis position at the top of the mounting frame 20, and the positioning and fixing are achieved by the cooperation of the clip 40 set thereon and the slot 21 on the mounting frame 20, so that the inspection camera 31 is vertically facing the upper surface of the item to achieve the acquisition of a top view image. If it is necessary to acquire a side image of the item, the operator can... Release the latch 40 and slide the detection seat 30 along the arc-shaped trajectory of the mounting frame 20 to acquire images of the sides (left and right). This allows the detection camera 31 to sequentially acquire images of the top surface and sides of the object. Furthermore, since the detection seat 30 can move flexibly on the mounting frame 20, even when the object is offset from the center of the worktable 11, accurate imaging and dimensional measurement of its top surface and sides can be achieved by adjusting the camera position. This avoids the drawbacks of traditional measuring devices that require frequent moving or rotating of the object due to the fixed camera, significantly improving detection efficiency and convenience. It is simple to operate and highly efficient.

[0021] Specifically, such as Figure 2-3 As shown in this embodiment of the present invention, the locking member 40 includes a movable plate 41 slidably engaged with the detection seat 30. The movable plate 41 is provided with a locking block 42 and a connecting rod 43. The connecting rod 43 passes through the detection seat 30 and is fitted with a spring 44. The spring 44 abuts against the detection seat 30 and the movable plate 41. When it is necessary to adjust the camera angle or position, the operator only needs to pull the movable plate 41 to compress the spring 44 and move the movable plate 41, thereby disengaging the locking block 42 from the slot 21. At this time, the detection seat 30 can slide on the arc-shaped track of the mounting bracket 20. After sliding to the desired position, the movable plate 41 is released. Under the elastic force of the spring 44, the locking block 42 re-embeds into the new locking slot 21, realizing the automatic locking of the detection seat 30 in the new position. In addition, in order to facilitate pulling the movable plate 41, the movable plate 41 has an auxiliary block 45 extending in the vertical direction, so that the operator can pull or release the movable plate 41 through the auxiliary block 45. Secondly, the detection seat 30 is provided with a sliding groove, and the movable plate 41 is provided with a limiting block 46. The limiting block 46 is locked in the sliding groove. By locking the limiting block 46 in the sliding groove, the movable plate 41 always slides along the sliding groove during the movement, so that the movable plate 41 can move up and down smoothly when pulled.

[0022] Based on the above solutions, such as Figure 3As shown, in a preferred embodiment of this utility model, the connecting rods 43 are configured as two, which are symmetrically distributed on the movable plate 41. The two connecting rods 43, together with the spring 44, provide dual-point guidance and elastic recovery for the movable plate 41, so that the movable plate 41 maintains a stable linear motion during the pulling or releasing process, and the movable plate 41 is subjected to balanced force during the up and down movement.

[0023] Specifically, such as Figure 2 As shown in this embodiment of the present invention, the mounting frame 20 is provided with a track groove 22 along its extension direction, and the detection seat 30 is provided with a pulley group 32. The pulley group 32 rolls and fits against the track groove 22 and can slide along the extension direction of the track groove 22. Through the rolling fit between the pulley group 32 and the track groove 22, low-friction sliding is achieved, making the detection seat 30 move more easily and smoothly along the mounting frame 20, significantly reducing the resistance of manual pushing, improving the operating experience, and increasing work efficiency.

[0024] Specifically, such as Figure 2 As shown in this embodiment of the utility model, the detection seat 30 is provided with a mounting ring 50, the mounting ring 50 forms a mounting cavity, the detection camera 31 is mounted in the mounting cavity, and the outer side of the mounting ring 50 is provided with a bolt 60 that penetrates into the mounting cavity. The bolt 60 is connected to the detection camera 31. By using the mounting ring 50 and the bolt 60 for connection, the detection camera 31 can be quickly installed and removed, so as to facilitate maintenance, adjustment or replacement of camera models, and improve the versatility and adaptability of the device.

[0025] Specifically, such as Figure 1 As shown in this embodiment of the utility model, the workbench 11 is rotatably mounted on the base 10, so that the object to be measured can be displayed from multiple angles under the view of the fixed detection camera 31. With the sliding movement of the detection seat 30, the measurement capability of different surfaces of the object is significantly improved.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
