[0052] Referring to Figures 1 to 14 As a specific scheme, the focusing device 300 is provided with an accommodation space 300a for accommodating at least a part of the lens 500.

[0053] The lens 500 can be detachably connected with the focusing device 300. For example, the lens 500 can be provided with an external thread (not shown in the figure), and the focusing device 300 is provided with an internal thread, and they are fixedly connected through the threaded connection. The thread standard of the plurality of lenses 500 used by the industrial camera 10 of the present application can be standardized, for example, the thread standard of M12 is adopted, and at the same time, different focusing devices 300 are also standardized, so that the lens 500 and the focusing device 300 can be universally adapted as needed.

[0054] Referring to Figures 1 to 14 In order to realize the function of the focusing device 300, as a specific scheme, the focusing device 300 includes a mounting sleeve 301, a transmission sleeve 302, a guide sleeve 303, a housing sleeve 304 and a locking bolt 305.

[0055] Specifically, the mounting sleeve 301 is used to fix the lens 500 and form the accommodation space 300a; the transmission sleeve 302 is used to drive the mounting sleeve 301 to move along the optical axis of the lens 500 when the transmission sleeve 302 rotates; the mounting sleeve 301 and the transmission sleeve 302 are rotatably and slidably connected; the guide sleeve 303 is used to guide the movement of the mounting sleeve 301; and the guide sleeve 303 and the transmission sleeve 302 are rotatably connected.

[0057] At this time, as long as the transmission sleeve 302 rotates, the axle block 301a is relatively slid by the combined action of the driving groove 302a and the guide groove 303a, the axle block 301a drives the mounting sleeve 301, and the mounting sleeve 301 further drives the lens 500 to realize the adjustment of the focal length.

[0058] The housing sleeve 304 is used to accommodate the mounting sleeve 301 and / or the transmission sleeve 302; the locking bolt 305 is used to lock the relative rotation of the mounting sleeve 301 and the housing sleeve 304; the housing sleeve 304 is provided with a locking hole for the locking bolt 305 to be screwed into contact with the mounting sleeve 301. In this way, the mounting sleeve 301 can be locked by operating the locking bolt 305 when adjusted in place, that is, the adjusted focal length is locked.

The housing sleeve 304, the transmission sleeve 302, the guide sleeve 303 and the mounting sleeve 301 are sequentially sleeved from the outside to the inside.

[0060] Referring to Figures 15 to 23 As another scheme of the present application, the industrial camera 10 shown is adjusted in focal length by automation.

[0061] Specifically, the focusing device 300 further comprises a focusing motor 306, a transmission gear 307 and a transmission gear ring 308. The focusing motor 306 is used to drive the transmission sleeve 302 to rotate; the focusing motor 306 is electrically connected with the camera body 100 or the functional device 200, so that the focusing motor 306 can also be controlled by the industrial computer in the system. More specifically, the focusing motor 306 can be directly connected with the camera body 100, and of course can also be indirectly connected with the camera body 100 through the functional device 200, that is, as described above, the focusing motor 306 can be a link in the series connection of electric energy and signals of the camera body 100 and the functional device 200.

[0062] The transmission gear 307 is connected to the focusing motor 306; the transmission gear ring 308 is connected to the transmission sleeve 302 (not shown in FIG. 15 Figure 23 The transmission gear 307 is engaged with the transmission gear ring 308. As shown in the Figures 15 to 23 The industrial camera 10 shown can adopt the above-mentioned scheme of the housing sleeve 304, the transmission sleeve 302, the guide sleeve 303 and the mounting sleeve 301, and the gear ring can be rotationally fixed with the housing sleeve 304.

[0063] As a preferred scheme, the focusing motor 306 can be a stepper motor, and it can realize self-locking function.

[0064] In order to improve the convenience of the overall arrangement, Figures 15 to 23The camera body 100, the functional device 200 and the focusing device 300 in the industrial camera 10 shown are fixedly connected as a whole, and the focusing device 300 is formed with two mounting flanges 309 to be fixedly connected with the camera body 100 and the functional device 200 respectively. Of course, this does not mean that the camera body 100, the functional device 200 and the focusing device 300 cannot be disassembled, but only that the connection of the three is not designed for disassembly and assembly for frequency division, but Figures 1 to 14 The disassemblable connection of the camera body 100, the functional device 200 and the focusing device 300 in the industrial camera 10 shown is designed for the convenience of disassembly and separation for the user.

[0065] Referring to Figure 23 It is shown that Figures 15 to 23 In the industrial camera 10 shown, the functional device 200 can still be replaced as needed. As a preferred solution, the functional device 200 comprises: a functional element; the functional element is at least configured as an illumination element. That is, the functional device 200 can be an illumination device such as a fill light or a flood light. Of course, the functional element can also be an actuating element commonly used in industrial production lines such as a motor, a solenoid valve, a switch, etc.

[0066] Figures 15 to 23 In the industrial camera 10 shown, a second circuit board 400 can be provided to realize the electrical connection between the functional element, the device terminal 201 and the extension terminal 203.

[0067] Referring to Figures 24 to 26 It is shown that the circuit architecture of the industrial camera 10 of the present application is described below.

[0068] Specifically, the camera body 100 comprises: a camera controller; the camera controller is used to control image acquisition and output control signals for controlling the functional device 200 and / or the focusing device 300. The focusing device 300 comprises a focusing controller, and the focusing controller is used to control the operation of the focusing motor 306.

[0069] In Figures 1 to 14 In the industrial camera 10 shown, there is no focusing motor 306, so referring to Figure 24 It is shown that the camera body 100 realizes the electrical connection of the camera controller with the power supply terminal 101, the signal terminal 102 and the external terminal 103 through the first circuit board 107. The second circuit board 400 realizes the electrical connection between the functional element, the device terminal 201 and the extension terminal 203. Then the electrical energy and signal transmission between the camera body 100 and the functional device 200 is realized through the connection of the external terminal 103 and the device terminal 201.

[0070] In Figures 15 to 23The focus controller is electrically connected to the second circuit board 400, and thus indirectly connected to the first circuit board 107, which is equivalent to the camera controller and the focus controller being connected to one circuit board, so that they can transmit electric energy and signals to each other. As an extension, the external terminal 103 and the device terminal 201 can be removed, and the first circuit board 107 and the second circuit board 400 can be directly connected, or the first circuit board 107 and the second circuit board 400 can be directly combined into one circuit board.

[0071] Referring to Figure 25 As shown, the camera controller outputs control signals of the control device 200 and / or the focusing device 300 according to external signals accessed through the signal terminal 102. The functional element is electrically connected to the power supply terminal 101 to use electric energy accessed through the power supply terminal 101; the camera controller is electrically connected to the expansion terminal 203 to output control signals to the outside through the expansion terminal 203; and the camera controller is electrically connected to the focusing device 300 to output control signals for controlling the focusing motor 306.

[0072] More specifically, the camera controller and the focus controller interact with each other, so that the focus controller drives the focusing motor 306 according to the control signals of the camera controller. Of course, the focus controller can also obtain electric energy and control signals from the power supply terminal 101 or the signal terminal 102. As an optional solution, the camera controller and the focus controller can be integrated into one controller.

[0073] Referring to Figure 26 As shown, the functional device 200 can include a device switch 206, such as a MOS tube, for turning on or off the power supply circuit of the functional element. The camera controller is electrically connected to the device switch 206 to output control signals of the device switch 206. That is, the power supply of the functional element can come from the device terminal 201, and the driving signal of the device switch 206 can come from the external terminal 103, which is equivalent to the camera body 100 being able to drive the functional element through the device switch 206.

[0074] As a second aspect, the industrial line detection system of the present application can include the industrial camera 10 as described above, and can include one or more.

[0075] As described above, the industrial camera of the present application can integrate the camera body, the focusing lens, the light source and its controller into one whole, so that the industrial camera of the present application has the following functions at the same time.

[0076] 1、Camera body: collect detection images and transmit the detection images to the industrial computer or server of the production line; at the same time, the camera body controls the parameters such as image collection, focal length and illumination according to the instructions of the industrial computer or server of the production line.
