DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0023] Example 1

[0024] The present embodiment provides a handheld mobile visual inspection device, which includes: an assembly mechanism 100; a positioning mechanism 200, wherein the positioning mechanism 200 is connected to the assembly mechanism 100 and includes a distance sensor 210 and a laser generator 220, wherein the distance sensor 210 and the laser generator 220 are both arranged toward the component to be inspected to locate the recognition angle and the recognition distance; an identification mechanism 300, wherein the identification mechanism 300 includes a recognition camera 310, wherein the recognition camera 310 is connected to the assembly mechanism 100 and is arranged toward the component to be inspected, and the recognition camera 310 is respectively connected to the distance sensor 210 and the laser generator 220 for signal connection.

[0025] The handheld mobile visual inspection device described in this embodiment assembles the positioning mechanism 200 and the identification mechanism 300 through the assembly mechanism 100. During the scanning detection process, the positioning mechanism 200 locates the distance to the element to be detected through the distance sensor 210, and the laser generator 220 locates the detection angle and direction of the element to be detected, so that the identification mechanism 300 can be identified in a specific position, thereby greatly improving the detection accuracy of the handheld mobile visual inspection device. In addition, compared with the conventional detection technology at this stage, the present application has significant advantages such as strong compatibility, flexible use, easy operation and small detection error, and has broad application prospects in this industry.

[0026] See also Figure 1As shown, the assembly mechanism 100 includes a connecting frame 110 and a protective cover 140. The protective cover 140 and the connecting frame 110 together enclose a storage space. The positioning mechanism 200 and the identification mechanism 300 are both connected to the connecting frame 110 and are both arranged inside the protective cover 140. Specifically, the connecting frame 110 in this embodiment includes a bottom plate and side plates, wherein the bottom plate is used to support the positioning mechanism 200 and the identification mechanism 300, and the side plates are used to realize lateral protection of the positioning mechanism 200 and the identification mechanism 300 together with the protective cover 140. Furthermore, the bottom plate, side plates and protective cover 140 in this embodiment are all detachably connected to each other to facilitate subsequent maintenance or replacement of internal components.

[0027] The protective cover 140 in this embodiment is preferably a special-shaped mesh hard component that matches the appearance of the positioning mechanism 200 and other mechanisms, and is provided with a plurality of heat dissipation holes 141. During actual use, as the use time increases, the identification mechanism 300 and the positioning mechanism 200 may both generate heat. At this time, the heat dissipation holes 141 can be used to dissipate heat and cool the internal structure of the protective cover 140, thereby improving the operating accuracy and service life of the positioning mechanism 200 and the identification mechanism 300.

[0028] See also Figure 2 As shown, the assembly mechanism 100 in this embodiment also includes a handle 120, which is connected to the connecting frame 110 and is provided with a button 121. The button 121 is signal-connected to the positioning mechanism 200 and the identification mechanism 300, respectively. During actual use, the operator can move the device through the handle 120, thereby improving the flexibility of use of the device. The button 121 is connected to an external power supply device. When the button 121 is pressed, the positioning mechanism 200 and the identification mechanism 300 can perform normal detection operations, thereby improving the flexibility and operability of the device.

[0029] Furthermore, the assembly mechanism 100 of this embodiment further includes a connecting wire 130, through which the handle 120 is connected to an external power supply. In actual use, the power supply includes, but is not limited to, a mobile power supply, a fixed power supply, a DC power supply, an AC power supply, a wireless power supply, and other structures capable of powering the device, and this utility model does not impose any specific restrictions on these.

[0030] See also Figure 2 and Figure 3As shown, the distance sensor 210 in this embodiment includes a transmitter 211 and a receiver 212. After the distance detection light is emitted by the transmitter 211, it is transmitted through the component to be detected and received by the receiver 212. Specifically, when positioning, the transmitter 211 of the distance sensor 210 emits a detection light, which is reflected by the surface of the component to be detected and received by the receiver 212. Thus, a specific distance detection and analysis process can be performed by analyzing parameters such as the interval time between the transmitter reception and the reception intensity at the receiver. Furthermore, the laser emitter in this embodiment is used to identify the relative angle and direction between the identification mechanism 300 and the component to be detected. When the distance sensor 210 detects that the component is within the detection distance and the laser emitter detects that the detection angle and direction of the component meet the detection requirements, the identification mechanism 300 will be activated, thereby achieving the optimal detection effect. Specifically, the laser emitter in this embodiment is preferably a straight laser emitter. In different embodiments, the laser emitter can be adaptively adjusted according to actual needs.

[0031] In this embodiment, the recognition camera 310 includes a zoom lens, and the light source 320 is used to increase the amount of light collected by the recognition camera 310. The zoom lens can help improve the detection accuracy of the recognition camera 310 within a certain distance. In different embodiments, different numbers, positions, or types of light sources 320 can be provided based on actual usage requirements, and this invention does not impose specific limitations on this.

[0032] This embodiment also includes a control system. During the actual production and processing process, the operator can use the control system to adjust the above structure in real time, thereby improving the flexibility of the use of this equipment. The operator can also preset parameters through the control system, thereby improving the degree of automation of this equipment.

[0033] Example 2

[0034] This embodiment provides a detection system, which includes the handheld mobile visual detection device described in the first embodiment.

[0035] In summary, the handheld mobile visual inspection device and inspection system described in the present invention assemble the positioning mechanism 200 and the identification mechanism 300 through the assembly mechanism 100. During the scanning and inspection process, the positioning mechanism 200 locates the distance to the element to be inspected through the distance sensor 210, and the laser generator 220 locates the detection angle and direction of the element to be inspected, so that the identification mechanism 300 can be identified in a specific position, thereby greatly improving the inspection accuracy of the handheld mobile visual inspection device. In addition, compared with the conventional inspection technology at this stage, the present application has significant advantages such as strong compatibility, flexible use, easy operation and small detection error, and has broad application prospects in this industry.

[0036] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible.
