[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0044] Figure 1 is a schematic diagram of a film reading terminal according to an exemplary embodiment. Figure 1 ,like Figure 1 As shown, the film reading terminal includes:

[0045] Display device 1, physical film recognition device 2, film reading light 3 and housing 4;

[0046] The film reading lamp 3 is located in the housing 4. In order to enhance the supporting strength of the housing 4, the housing 4 in the present application may be made of sheet metal.

[0047] A first opening is provided in the shell 4, and the position of the first opening corresponds to the reading position in the reading light 3. By providing the first opening in the shell 4, the inspector can place the physical film at the reading position in the reading light 3 to view the physical film.

[0048] The display device 1 is located outside the housing 4.

[0049] The physical film identification device 2 is used to obtain the identification code on the physical film and upload it; an identification code can be preset in the physical film, and this identification code is used to uniquely identify the physical film, that is, the identification codes corresponding to each physical film are different.

[0050] Exemplarily, the identification code can be a string. Correspondingly, the physical film identification device 2 can include: a camera. When obtaining the identification code, the tester can aim the position of the string in the physical film at the camera for shooting. In this way, the camera can achieve the purpose of obtaining the string on the physical film. The identification code can also be a two-dimensional code. Correspondingly, the physical film identification device 2 can include: a two-dimensional code identification device. The tester can aim the two-dimensional code in the physical film at the two-dimensional code identification device. In this way, the two-dimensional code identification device can achieve the purpose of obtaining the two-dimensional code on the physical film.

[0051] The physical film identification device 2 can be separated from the housing 4 and placed beside the housing 4, or can be fixedly installed outside the housing 4.

[0052] The display device 1 is used to receive and display the digital film image calibrated with the identification code and showing the defects.

[0053] After the physical film identification device 2 obtains the identification code on the physical film, it will upload it to the device that can obtain the digital film corresponding to the physical film based on the identification code (it should be noted that the defect information is also calibrated in this digital film). In this way, when this device obtains the digital film corresponding to the physical film, it will send it to the display device 1. After the display device 1 receives the digital film corresponding to the physical film, it will display it for the tester to view the digital film and the defect information in the digital film.

[0054] Meanwhile, after obtaining the identification code on the physical film through the physical film identification device 2 and uploading it, the tester can place the physical film at the film viewing position in the film viewer 3. In this way, the tester can compare and view the defects calibrated in the digital film with the physical film, so as to more accurately determine the defects in the physical film and improve the accuracy of the detection result.

[0055] In another implementable manner, after the identification code on the physical film is obtained by the physical film identification device 2 and uploaded, the inspector may not place the physical film at the film viewing position in the film viewer 3 first, but first view the defects marked in the digital film displayed on the display device 1. If the inspector has doubts about the defects marked in the digital film, the physical film can be placed at the film viewing position in the film viewer 3 at this time, and then compared. In this way, the inspector can pay more attention to the problems reflected by the marked defects, improving work efficiency and accuracy.

[0056] Exemplarily, the display device 1 may include a computer display screen. Since the computer display screen has advantages such as high resolution and high color restoration, it can clearly display the details of the digital film, providing more accurate defect information for the inspector.

[0057] In one embodiment, as Figure 2 and Figure 3 shown, the film viewing terminal further includes: a host 5;

[0058] The host 5 is respectively connected to the display device 1 and the physical film identification device 2;

[0059] The digital film image corresponding to the identification code of the physical film and the defect information in the physical film are pre-stored in the host 5. The host 5 is used to find the digital film image corresponding to the identification code according to the identification code recognized by the physical film identification device 2, and send the found digital film image to the display device 1 for display.

[0060] That is, after the physical film identification device 2 obtains the identification code on the physical film, it will upload it to the host 5. The digital film corresponding to the physical film is pre-stored in the host 5, and the defect information is marked in the digital film. When the user needs to identify the weld problem in the physical film, after the physical film identification device 2 identifies the identification code of the current physical film, the physical film identification device 2 sends the identification code to the host 5. After the host 5 finds the digital film corresponding to the identification code from its own database, it controls the display device 1 to display. At this time, the digital film displayed on the display device 1 includes defect information. At the same time, when the user places the current physical film in front of the film viewer, the defect information in the digital film displayed on the display device 1 and the current physical film placed in front of the film viewer 3 can be compared, so as to accurately determine the defects in the current physical film and improve the accuracy of the detection result.

[0061] Among them, the physical film identification device 2 can be connected to the host 5 through a USB connection line, and the display device 1 is connected to the host 5 through an HDMI connection line.

[0069] The other end of the first support portion 6 is provided with a second fixing hole;

[0070] The detachable fastener successively passes through the second fixing hole and the first fixing hole to fixedly connect the first support portion 6 and the second support portion 7.

[0071] Exemplarily, the detachable fastener may include: a bolt; the hole walls of the second fixing hole and the first fixing hole are both provided with threads, and the first support portion 6 may be a hollow structure. During installation, a target first fixing hole with a satisfactory height position can be selected in the first fixing holes, then the second fixing hole is aligned with the target first fixing hole, and the bolt is successively screwed into the second fixing hole and the first fixing hole, so as to realize the fixed connection between the first support portion 6 and the second support portion 7. When the height needs to be adjusted, only the bolt needs to be screwed out of the second fixing hole and the first fixing hole, and then a new first fixing hole is selected, and the above fixing process is executed.

[0072] In one implementable manner, in order to achieve the purpose of adjusting the height of the display device 1, the second support portion 7 may be set as a structure with a telescopic length, and this telescopic structure may be similar to the telescopic structures in the related art and will not be elaborated here.

[0073] In one implementable manner, in order to achieve the purpose of enabling the angle of the display device 1 facing the inspector to be adjustable, the first support portion 6 includes a first rotating portion and a second rotating portion;

[0074] One end of the first rotating part is connected to the outer side of the display device 1; for example, one end of the first rotating part is connected to the outer side of the display device 1.

[0075] The other end of the first rotating part is provided with a first rotating shaft mounting hole, and one end of the second rotating part is provided with a second rotating shaft mounting hole.

[0076] The other end of the second rotating part is connected to one end of the second supporting part 7.

[0077] The first supporting part 6 is composed of two parts, and these two parts are rotatably connected by a rotating shaft. When the angle of the display device 1 needs to be adjusted, only need to rotate the first rotating part around the rotating shaft.

[0078] For aesthetics, the connection lines of the display device 1 can be hidden. The second supporting part 7 can be set as a hollow structure, and a wire passing hole is opened at a position close to the first supporting part in the second supporting part 7. Among them, the hollow part is used to store the connection lines of the display device 1; correspondingly, a through hole is opened at a position in the housing corresponding to the other end of the second supporting part 7. One end of the connection line is connected to the display device 1, and the other end of the connection line passes through the wire passing hole, the hollow structure and the through hole in sequence and is connected to the host 5.

[0079] In one implementable manner, a power interface is provided on the housing 4. One end of the power interface is respectively connected to the display device 1, the physical film recognition device 2, the film viewing lamp 3 and the host 5; the other end of the power interface is used to connect to an external power supply. The power interface facilitates the overall access to power and provides electrical energy for the film viewing device.
