[0060] 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 based on the present application belong to the scope of protection of the present application.

[0061] As mentioned in the background technology, industrial cameras are a key component in machine vision systems. Their most essential function is to convert light signals into orderly electrical signals. Industrial cameras usually include: camera body, sensor, lens and controller.

[0062] At present, industrial cameras can be divided into many types according to their lens interface types, such as S-mount cameras, C-mount cameras, etc. Among them, due to the large differences in the shapes of different lens interfaces, cameras with different lens interfaces need to be developed separately, resulting in high development and production costs.

[0063] In view of the above technical problems, the embodiment of the present application provides an industrial camera that is compatible with S-mount cameras and C-mount cameras, and can modularly install the built-in light source of the S-mount camera and multiple extended light sources. Figure 1a and Figure 1b Install the self-contained light source as shown, or Figure 1c and Figure 1g Install the first and second extended light sources as shown to increase the illumination; when the industrial camera is installed with a C-mount camera, Figure 2a As shown, no light source is installed, and Figure 2b and Figure 2eThe first and second extended light sources are installed as shown. Some of the structural parts of the above six types of industrial cameras can be shared and designed in common mode, which can reduce development and production costs. The installation method of the S-mount camera, C-mount camera and extended light source is simple and reliable, which is convenient for customers to replace. The hardware boards and structures of the whole machine can be reused, and the cost is low. The industrial camera provided in the embodiment of the present application is described in detail below.

[0064] See also Figure 1a to Figure 1g as well as Figure 2a , Figure 1a A three-dimensional structural diagram of an industrial camera provided in an embodiment of the present application when an S-shaped lens module is installed; Figure 1b for Figure 1a A cross-sectional view of the industrial camera shown; Figure 1c A three-dimensional structural diagram of an industrial camera provided in an embodiment of the present application when an S-shaped lens module and a first extended light source are installed; Figure 1d for Figure 1c A three-dimensional structural diagram of the industrial camera from another angle; Figure 1e for Figure 1c A cross-sectional view of the industrial camera shown; Figure 1f for Figure 1c An exploded schematic diagram of the industrial camera shown; Figure 1g for Figure 1c An exploded schematic diagram of the industrial camera shown; Figure 2a This is a three-dimensional structural diagram of the industrial camera provided in an embodiment of the present application when a C-type lens module is installed.

[0065] like Figure 1a to Figure 1g as well as Figure 2a As shown, the industrial camera includes: a main housing 100 , an S-type lens mounting cover 200 or a C-type lens mounting cover 300 , an S-type lens module 400 or a C-type lens module 500 , and a control module 600 .

[0066] A mounting opening is provided on one side of the main shell 100; an S-type lens mounting cover 200 or a C-type lens mounting cover 300 is detachably covered on the mounting opening to form a mounting cavity 101; a control module 600 is installed in the mounting cavity 101 and is detachably electrically connected to the S-type lens module 400 or the C-type lens module 500.

[0067] The S-type lens module 400 is installed on the S-type lens mounting cover plate 200 ; the C-type lens module 500 is installed on the C-type lens mounting cover plate 300 .

[0068] The S-type lens mounting cover plate 200 is obtained by processing a C-type lens mounting cover plate 300 according to the structural requirements of the S-type lens module 400 .

[0069] Specifically, Figure 1a and Figure 1eAs shown, the main housing 100 is approximately in the shape of a cuboid, wherein the above-mentioned mounting opening (not shown in the figure) is provided on one side for mounting the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300. In the present application, the main housing 100 may also be in other shapes, such as a cylinder, etc., which is not limited in the present application.

[0070] like Figure 1a and Figure 1d As shown, the main housing 100 is also movably connected with a rotating aviation head 110, which is electrically connected to the control module 600. The rotating aviation head 110 is provided with two external interfaces 111, which are a data interface and a power interface. The data interface is used to transmit the captured data, and the power interface is used to connect the power supply. The rotating aviation head 110 can rotate along the contact slope relative to the main housing 100 to adjust the direction of the external interface 111, so that the industrial camera can adapt to a variety of installation positions. When using the industrial camera, the rotation angle of the rotating aviation head 110 can be adjusted according to different installation positions to connect the industrial camera to external equipment.

[0071] The industrial camera can be compatible with two types of lens modules, namely, the S-type lens module 400 and the C-type lens module 500. The difference between the S-type lens module 400 and the C-type lens module 500 is that the installation interfaces are different, and the S-type lens module 400 can be controlled by the control module 600 to automatically adjust the focal length, while the C-type lens module 500 needs to adjust the focal length manually.

[0072] When the S-type lens module 400 is needed, the S-type lens mounting cover plate 200 needs to be mounted on the mounting opening of the main housing 100, and then the S-type lens module 400 needs to be mounted on the S-type lens mounting cover plate 200; when the C-type lens module 500 needs to be used, the S-type lens mounting cover plate 200 needs to be replaced with the C-type lens mounting cover plate 300, and then the C-type lens module 500 needs to be mounted on the C-type lens mounting cover plate 300. When replacing the lens module, only the lens mounting cover plate needs to be replaced, and the main housing 100 and the control module 600 inside the main housing 100 and other structural components can continue to be used, which is simple and convenient to replace, and also reduces the development and production costs.

[0073] The embodiment of the present application provides such an industrial camera, including an S-type lens mounting cover plate 200 or a C-type lens mounting cover plate 300, and an S-type lens module 400 or a C-type lens module 500; the S-type lens module 400 is mounted on the S-type lens mounting cover plate 200, and the C-type lens module 500 is mounted on the C-type lens mounting cover plate 300. The S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300 can be detachably covered on the mounting opening of the main housing 100, so that the industrial camera can be adapted to install different lenses, and compatible installation of multiple lenses is achieved; and when installing different lenses, only the lens mounting cover plate is replaced, and other components can be reused, and there is no need to develop multiple industrial cameras separately, thereby reducing development and production costs. The S-type lens mounting cover plate 200 is obtained by processing a C-type lens mounting cover plate 300 according to the structural requirements of the S-type lens module 400, that is, the two lens mounting cover plates are designed in a common mold, which can reduce development and production costs.

[0074] In some embodiments of the present application, see Figure 3a and Figure 3b , Figure 3a for Figure 2a The three-dimensional structure diagram of the C-type lens mounting cover shown; Figure 3b for Figure 2a The three-dimensional structure diagram of the industrial camera shown is when the C-type lens module is removed.

[0077] Specifically, Figure 3a As shown, when installing the C-type lens module 500, it is only necessary to insert the end of the C-type lens module 500 into the C-type lens mounting convex hole 320. The end of the C-type lens module 500 and the inner wall of the C-type lens mounting convex hole 320 can be threaded or clamped.

[0078] By using the embodiment of the present application, the C-type lens module 500 can be installed by only providing the C-type lens installation convex hole 320 on the substrate 310 , thereby simplifying the installation process.

During preparation, the plate material is first made into a substrate 310 pattern of the C-type lens mounting cover plate 300, which has a C-type lens mounting convex hole 320, and then according to the required quantity of the S-type lens mounting cover plates 200, the required quantity of the substrate 310 is cut to obtain the S-type lens mounting cover plates 200.

[0086] An opening is provided on the end surface of the S-type lens light source assembly housing 422 close to the S-type lens mounting cover 200 , so that the S-type lens 411 can extend through the opening to the inside of the S-type lens light source assembly housing 422 .

[0087] The S-type lens light source assembly housing 422 is provided with a lens light entrance hole 4221 and a plurality of light exit holes 4222 arranged around the lens light entrance hole 4221 ; the position of the lens light entrance hole 4221 corresponds to the S-type lens 411 ; and a plurality of light emitting devices 421 are installed at the plurality of light exit holes 4222 .

The fixed mounting portion 4122 is used to connect with the S-type lens mounting cover plate 200, and the fixed mounting portion 4122 is arranged on the mounting cavity 101, and is fixedly connected with the S-type lens mounting cover plate 200 on one side of the mounting cavity 101, and can be fixedly connected by threaded fasteners; a mounting hole is provided in the center of the lens mounting portion 4121, and is used to insert the S-type lens 411. The lens mounting portion 4121 passes through the S-type lens module mounting through hole 210 and extends to the outside of the mounting cavity 101, so that the S-type lens 411 can be installed outside the mounting cavity 101.

[0089] The S-type lens 411 is provided with an interface for connecting to the control module 600 , and can automatically adjust the focal length under the control of the control module 600 .

[0090] The S-type lens light source assembly 420 is a self-contained light source of the S-type lens module 400, which is used to illuminate the object to be measured to increase the illumination. The S-type lens light source assembly 420 is covered on the S-type lens assembly 410, making the structure of the S-type lens module 400 more compact and reducing the size of the industrial camera.

[0091] The position of the lens light entrance hole 4221 is directly opposite to the light entrance end of the S-type lens 411, so that the reflected light of the object to be measured passes through the lens light entrance hole 4221 and enters the light entrance end of the S-type lens 411, thereby realizing lens imaging; the position of the light exit hole 4222 is directly opposite to the multiple light-emitting devices 421, thereby increasing the illumination of the object to be measured and allowing more light to enter the light entrance end of the S-type lens 411.

[0092] like Figure 6 As shown, the light emitting device 421 is arranged around the S-shaped lens 411, so that the S-shaped lens light source assembly 420 can illuminate the object to be measured more evenly and make the lens imaging clearer.

[0093] The process of installing the S-type lens module 400 is as follows: first fix the S-type lens mounting base 412 on the S-type lens mounting cover 200, then fix the S-type lens 411 on the S-type lens mounting base 412, and electrically connect the S-type lens 411 to the control module 600, then cover the S-type lens light source assembly 420 on the S-type lens 411, and electrically connect the S-type lens light source assembly 420 to the control module 600.

[0094] In some embodiments of the present application, Figure 1d , Figure 5 and Figure 6 As shown, the S-shaped lens light source assembly 420 further includes: a first transparent cover plate 423. The material of the first transparent cover plate 423 can be transparent materials such as glass and plastic, which is not limited in the present application.

[0095] The first transparent cover plate 423 is arranged on the end surface of the S-type lens light source assembly housing 422 away from the S-type lens mounting cover plate 200, so that the light emitted by the multiple light-emitting devices 421 can pass through the first transparent cover plate 423 and be emitted to the outside of the industrial camera, and the external light can pass through the first transparent cover plate 423 and enter the S-type lens 411.

[0096] By using the embodiment of the present application, a first transparent cover plate 423 is provided, which can protect the internal parts of the S-type lens light source assembly 420 and seal against dust, so as to improve the protection level of the industrial camera. The first transparent cover plate 423 is made of a transparent material with good light transmittance, and can allow sufficient external light to enter the S-type lens 411 to ensure the imaging quality of the lens.

[0097] In some embodiments of the present application, Figure 5 and Figure 6 As shown, the S-type lens light source assembly 420 also includes: a lens bracket 424, a lamp board 425 and a light source driving board 426. The lens bracket 424, the lamp board 425 and the light source driving board 426 are sleeved on the S-type lens 411 and arranged in sequence along the incident direction of the external light. A plurality of light emitting devices 421 are mounted on the lamp board 425, and the positions correspond to the light exit holes 4222 respectively.

[0098] The lens bracket 424 is used to support the lamp board 425 and the light source driving board 426 . The lamp board 425 is electrically connected to the control module 600 through the light source driving board 426 .

[0099] Specifically, through holes are provided in the middle of the lens bracket 424, the light board 425 and the light source driving board 426 for the S-type lens 411 to pass through. The S-type lens light source assembly 420 is an integral module, which is generally shipped as a complete unit. The internal structure does not need to be assembled by the user. It is only necessary to connect the S-type lens light source assembly housing 422 with the S-type lens mounting cover 200, so that the S-type lens light source assembly 420 has a high degree of modularity, a simple installation method, and strong ease of use.

[0100] like Figure 5 and Figure 6As shown, in addition to the light emitting device 421, the light board 425 is also provided with an aiming light 4251 and a ranging sensor 4252; the aiming light 4251 is used to point to the center of the field of view of the industrial camera and project a triangular light spot on the object to be measured; the ranging sensor 4252 can be a TOF sensor, which is used to detect the distance to the object to be measured, so that the control module 600 adjusts the focal length of the S-type lens 411 according to the detection signal.

[0101] The S-type lens light source assembly 420 also includes a light-isolating foam 427, which is covered on the lens bracket 424. The light-isolating foam 427 is hollowed out at the positions corresponding to the light-emitting device 421, the aiming light 4251 and the ranging sensor 4252, and is used to isolate the light emitted by the above three devices to prevent light from leaking between the devices. In addition, the surface of the light-isolating foam 427 is flat, which will press the lens bracket 424 to ensure the flatness of the lens bracket 424, and then ensure the consistency of the light-emitting angles of the above three devices.

[0102] Using the embodiment of the present application, the lamp board 425 is electrically connected to the light source driving board 426 , and the control module 600 can drive the lamp board 425 to start or stop working through the light source driving board 426 .

[0103] In some embodiments of the present application, Figure 1a and Figure 5 As shown, the S-type lens light source assembly housing 422 includes: a light source base 4223 and a light source modification cover 4224.

[0104] The light source base 4223 is detachably connected to the S-shaped lens mounting cover 200 .

[0105] The light source modification cover 4224 and the lens bracket 424 are both provided with light exit holes 4222 , so that the light emitted by the light emitting device 421 can pass through the light exit holes 4222 and be emitted to the outside of the industrial camera.

[0106] Specifically, a light source upper cover 4225 may also be provided between the light source base 4223 and the light source modification cover 4224. The light source upper cover 4225, the light source modification cover 4224 and the light source base 4223 are sequentially connected along the incident direction of external light. The light source upper cover 4225 and the light source modification cover 4224 may be integral or detachable. The light source upper cover 4225 and the light source base 4223, as well as the light source base 4223 and the S-type lens mounting cover plate 200 are sealed by a sealing strip 4226 to prevent dust and other pollutants in the external air from entering, so as to ensure the airtightness of the S-type lens light source assembly 420 and the mounting cavity 101 and improve the protection level.

[0107] In the application embodiment of the present application, a light source modification cover 4224 is provided, and a lens light entrance hole 4221 is provided on the light source modification cover 4224 and the lens bracket 424. The arrangement of the lens light entrance hole 4221 and the light exit hole 4222 corresponds to the S-type lens 411 and the light emitting device 421, so that external light can enter the S-type lens 411 through the lens light entrance hole 4221, and the light emitted by the light emitting device 421 can pass through the light exit hole 4222 and be emitted to the outside of the industrial camera.

[0108] In some embodiments of the present application, see Figure 7 , Figure 7 for Figure 1a The three-dimensional structure diagram of the control module connected to the S-type lens mounting cover is shown. Figure 1b , Figure 1e , Figure 2c and Figure 7 As shown, the control module 600 includes: a sensor 610 , a main board 620 and an interface board 630 .

[0109] The sensor 610 and the main board 620 are both electrically connected to the interface board 630; the S-type lens module 400 is detachably electrically connected to the interface board 630. The interface board 630 is electrically connected to an external power source for supplying power to the sensor 610, the main board 620 and the S-type lens module 400.

[0110] The sensor 610 is located at the S-type lens module mounting hole 210, and is directly opposite to the S-type lens module 400 through the S-type lens module mounting hole 210, or is directly opposite to the C-type lens module 500 through the C-type lens mounting convex hole 320; the sensor 610 is used to receive light transmitted from the S-type lens module 400 or the C-type lens module 500, and convert the optical signal into an electrical signal and transmit it to the mainboard 620.

[0111] Specifically, Figure 1b As shown, the sensor 610 , the interface board 630 and the main board 620 are sequentially arranged in a spaced relationship along a direction from the S-type lens light source assembly 420 to the mounting cavity 101 .

[0112] The interface board 630 is provided with a first seat (not shown in the figure) for electrically connecting to the rotary aviation head 110 to provide power for the sensor 610 , the main board 620 and the S-type lens module 400 .

[0113] like Figure 1b and Figure 7 As shown, a sensor socket 611 is provided on one side of the sensor 610 facing the interface board 630 , and is an FPC socket; the sensor socket 611 is electrically connected to a second socket 632 on the interface board 630 through an FPC line.

[0114] The S-type lens assembly 410 and the S-type lens light source assembly 420 of the S-type lens module 400 are both detachably electrically connected to the interface board 630. Among them, the S-type lens 411 of the S-type lens assembly 410 has a connecting cable 4111; the connecting cable 4111 is detachably electrically connected to the lens interface (not shown in the figure) of the interface board 630. The light source driving board 426 of the S-type lens light source assembly 420 is provided with a light source driving board seat 4261, and the light source driving board seat 4261 is detachably electrically connected to the third seat (not shown in the figure) on the interface board 630.

[0115] The interface board 630 is also provided with a fourth seat 634 , which is electrically connected to the expansion port adapter board 640 mentioned later, so as to provide power for the expansion light source 700 .

[0116] The main board 620 is electrically connected to the above components through the interface board 630, so as to realize the control of each component, for example, controlling the brightness of the S-type lens light source assembly 420 and the extended light source 700, and adjusting the focal length of the S-type lens 411. The main board 620 is provided with an image processor, which can receive and process the electrical signal sent by the sensor 610.

[0117] A heat sink 650 made of copper is provided on a side of the mainboard 620 away from the interface board 630 for dissipating heat from the mainboard 620 .

[0118] By applying the embodiment of the present application, a sensor 610, a main board 620 and an interface board 630 are set. The sensor 610 can receive an optical signal transmitted from the S-type lens module 400 or the C-type lens module 500, and transmit the signal with the image processor on the main board 620 through the interface board 630.

[0119] In some embodiments of the present application, see Figure 2b to Figure 2d , Figure 2b A three-dimensional structural diagram of an industrial camera provided in an embodiment of the present application when a C-type lens module and a first extended light source are installed; Figure 2c for Figure 2b A cross-sectional view of the industrial camera shown; Figure 2d for Figure 2b Exploded diagram of the industrial camera shown.

[0120] like Figure 2b to Figure 2d , Figure 3a and Figure 3b As shown, the C-type lens module 500 includes: a C-type lens 510 and a filter 520 .

[0121] The C-type lens 510 is vertically mounted on one side of the C-type lens mounting convex hole 320 outside the mounting cavity 101 ; the filter 520 is mounted on the other side of the C-type lens mounting convex hole 320 to cover the light emitting end of the C-type lens 510 .

[0122] Specifically, Figure 3a As shown, the C-type lens mounting convex hole 320 is a circular hole. A filter holder 521 is also provided in the C-type lens mounting convex hole 320 for mounting and fixing the filter 520. A square hole is provided in the center of the filter holder 521 so that the light output end of the C-type lens 510 can pass through the filter holder 521 and enter the filter 520.

[0123] like Figure 2a to Figure 2d As shown, the C-type lens module 500 further includes a lens cover 530. The lens cover 530 is arranged outside the C-type lens 510, and a transparent protective cover plate 531 is arranged on the end surface of the lens cover 530 opposite to the light-incoming end of the C-type lens 510, so that external light can pass through the protective cover plate 531 and enter the C-type lens 510. The outer side surface of the lens cover 530 is provided with tooth-shaped protrusions, so that the user can twist the lens cover 530 to manually adjust the focus.

[0124] Accordingly, if Figure 2c and Figure 3b As shown, a C-type lens adapter 330 can also be installed on the base plate 310 of the C-type lens mounting cover plate 300; the C-type lens adapter 330 surrounds the C-type lens mounting convex hole 320 to form an annular mounting groove 340 for leaving a mounting space for the C-type lens 510. The end of the lens cover 530 is threadedly connected to the outer wall of the C-type lens adapter 330.

[0125] When installing the C-type lens module 500, first, the C-type lens adapter 330 should be mounted on the C-type lens mounting convex hole 320; wherein, the diameter of the circular hole on the C-type lens adapter 330 is larger than the C-type lens mounting convex hole 320, so that an annular gap, i.e., the above-mentioned annular mounting groove 340, is formed between the C-type lens mounting convex hole 320 and the C-type lens adapter 330; then, the end of the C-type lens 510 of the C-type lens module 500 is inserted into the C-type lens mounting convex hole 320 and fixed, and finally, the end of the lens cover 530 is mounted on the outer wall of the C-type lens adapter 330 and tightened to fix.

[0126] The substrate 310 and the C-type lens adapter 330 may be integrated or may be Figure 3b The device shown is detachable, but this application does not limit this.

[0127] By using the embodiment of the present application, a filter 520 is provided to selectively pass light of a specific wavelength, so that the image is clearer and the measurement accuracy can be improved. A lens cover 530 is provided to protect the C-type lens 510 and prevent the C-type lens 510 from being damaged due to collision.

[0128] like Figure 2c and Figure 2dAs shown, the C-type lens module 500 further includes a sensor sealing pad 540 , which is disposed between the filter 520 and the sensor 610 to protect the sensor 610 .

[0129] Since the S-type lens mounting seat 412 of the S-type lens module 400 can play the same role as the sensor sealing gasket 540, the S-type lens module 400 does not need to be provided with a sensor sealing gasket.

[0130] The process of installing the C-type lens module 500 is as follows: a sensor sealing gasket 540 is covered on the sensor 610, and then the C-type lens mounting cover 300 is installed in the mounting opening of the main shell 100, and the filter 520 and the filter bracket 521 are placed in the C-type lens mounting convex hole 320, and then the C-type lens adapter 330 is installed in the C-type lens mounting convex hole 320 to form an annular mounting groove 340, and the C-type lens 510 is inserted into the C-type lens mounting convex hole 320, and the lens cover 530 is inserted into the annular mounting groove 340.

[0131] Compared with installing the S-type lens module 400, the sensor sealing gasket 540, filter 520, filter holder 521, C-type lens adapter 330, lens hood 530, and C-type lens 510 of the C-type lens module 500 need to be installed separately, and the C-type lens mounting cover 300 and the S-type lens mounting cover 200 can be designed in a common mold.

[0132] In some embodiments of the present application, Figure 1e , Figure 2c and Figure 7 As shown, the industrial camera further includes: an extended light source 700 ; the control module 600 further includes: an extended port adapter board 640 ; and the extended port adapter board 640 is electrically connected to the interface board 630 .

[0133] The extended light source 700 is disposed outside the mounting cavity 101 and is detachably connected to the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300 .

[0134] The expansion port adapter plate 640 is disposed in the installation cavity 101 and is detachably electrically connected to the expansion light source 700 .

[0135] Specifically, Figure 1b , Figure 1e , Figure 2c and Figure 7As shown, the sensor 610 and the expansion port adapter plate 640 are arranged side by side in the installation cavity 101, so that the interface of the extended light source 700 can avoid the S-type lens module 400 and the C-type lens module 500, and directly pass through the lens installation cover area next to the S-type lens module 400 and the C-type lens module 500, and connect with the expansion port adapter plate 640, making the structure more concise and beautiful, and easier to install.

[0136] An expansion port adapter plate seat 641 is provided on one side of the expansion port adapter plate 640 facing the interface plate 630 , and is electrically connected to the fourth seat 634 of the interface plate 630 .

[0137] By applying the embodiment of the present application, an expansion port adapter plate 640 is provided to connect the expansion light source 700, so as to increase the illumination of the object to be measured by the industrial camera and allow more light to enter the light input end of the S-type lens 411 or the C-type lens 510.

[0138] In some embodiments of the present application, Figure 1a , Figure 2a and Figure 3b As shown, an expansion port 801 and an expansion port cover 802 are provided on the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300 .

[0139] The expansion port 801 corresponds to the expansion port adapter plate 640 , and the expansion port cover plate 802 is detachably covered on the expansion port 801 .

[0140] Specifically, Figure 1a , Figure 2a and Figure 3b As shown, when the extended light source 700 does not need to be installed, the extended port cover 802 and the S-type lens mounting cover 200 or the C-type lens mounting cover 300 can be fixed by threaded fasteners.

[0141] When the extended light source 700 needs to be installed, the extended port cover 802 must be removed first. The extended port 801 exposes the interface on the extended port adapter plate 640 for connecting to the extended light source 700, so that the extended light source 700 can be connected to the extended port adapter plate 640. The interface board 630 supplies power to the extended light source 700 through the extended port adapter plate 640.

[0142] like Figure 3a and Figure 3b As shown, a circle of expansion port sealing groove 804 is arranged around the expansion port 801 for placing the expansion port sealing ring 805. When the expansion light source 700 is installed, the expansion port sealing ring 805 can be pressed by the expansion light source 700 to achieve the overall sealing of the camera and the expansion light source, and the whole device can achieve IP67 protection level.

[0143] In some embodiments of the present application, see Figure 8 , Figure 8 is a three-dimensional structural diagram of the first extended light source. Figure 1c to Figure 1e , Figure 2b to Figure 2d and Figure 8 As shown, the extended light source 700 is a first extended light source 700A; the first extended light source 700A is provided with a central mounting hole 701 .

[0144] The first extended light source 700A is detachably mounted on the outside of the S-type lens module 400 or the C-type lens module 500 through the central mounting hole 701 .

[0145] The first extended light source 700A includes: a first extended light board 710 and a first interface connection structure 720 electrically connected to the first extended light board 710 .

[0146] The first extended light board 710 is provided with a plurality of first extended light emitting devices 711 facing the object to be measured; the plurality of first extended light emitting devices 711 are arranged around the central mounting hole 701 .

[0147] The first interface connection structure 720 passes through the expansion port 801 and is detachably electrically connected to the expansion port adapter plate 640 .

[0148] Specifically, the first interface connection structure 720 is a pingo spring pin, which is mainly composed of a pin and a pull rod and has good elasticity and shock resistance. The pingo spring pin can form a stable triangular structure through the pin and the pull rod, can withstand large horizontal and vertical loads, and has good scalability, and can be expanded or modified as needed.

[0149] like Figure 1c and Figure 2b As shown, when installing the first extended light source 700A, first install the S-type lens module 400 or the C-type lens module 500, then align the central mounting hole 701 of the first extended light source 700A with the S-type lens module 400, so that the first extended light source 700A is mounted on the S-type lens module 400, and align the first interface connection structure 720, that is, the pingo spring pin, with the extended port adapter plate 640 to achieve circuit conduction.

[0150] In the embodiment of the present application, the first extended light source 700A is mounted outside the S-type lens module 400 or the C-type lens module 500, so that the industrial camera has a compact structure and a small volume. The first extended light source 700A is detachable, so that the user can install or remove the extended light source according to needs, so that the industrial camera can be applied to a variety of scenarios.

[0151] In some embodiments of the present application, Figure 1d , Figure 3a , Figure 4 and Figure 8As shown, the first extended light source 700A also includes: a first extended light source housing 730; a first connecting portion 731 is provided on the first side of the first extended light source housing 730; and a second connecting portion 803 is provided on the first side of the S-type lens mounting cover 200 or the C-type lens mounting cover 300.

[0152] The first connection portion 731 and the second connection portion 803 are detachably connected.

[0153] Specifically, Figure 1d and Figure 8 As shown, the first extended light source housing 730 includes a first extended light source upper cover 732 and a first extended light source base 733 which are sequentially arranged along the incident direction of the external light. The first extended light source base 733 and the outer surface of the main housing 100 are provided with a plurality of heat dissipation fins arranged at intervals, which are respectively used to dissipate heat for the first extended light source 700A and the control module 600.

[0154] The first extended light source housing 730 and the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300 can be detachably connected by threaded connection, snap connection or the like. Figure 1c and Figure 1d As shown, in this embodiment, one side of the first extended light source housing 730 and the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300 is connected by a first connecting portion 731 and a second connecting portion 803, and the other side is threaded. In other embodiments of the present application, both sides can be connected using the first connecting portion 731 and the second connecting portion 803, or can be threaded, and the present application does not limit this.

[0155] In this embodiment, if Figure 1d and Figure 8 As shown, the first extended light source upper cover 732 and the first extended light source base 733 are both provided with a central mounting hole 701, and the first connecting portion 731 is provided on the hole wall of the central mounting hole 701 of the first extended light source base 733. Figure 3a and Figure 4 As shown, the second connecting portion 803 is disposed on the lens mounting cover at a position opposite to the first connecting portion 731 .

[0156] In some embodiments of the present application, Figure 1d , Figure 3a , Figure 4 and Figure 8 As shown, the first connecting portion 731 is a male buckle extending toward the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300; the second connecting portion 803 is a female buckle with the same size as the male buckle; the male buckle and the female buckle can be snapped and separated, so that the first extended light source 700A is detachably connected to the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300, and / or,

[0157] The second side of the first extended light source housing 730 is threadedly connected to the second side of the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300 .

[0158] Specifically, when installing the S-type lens module 400 and the first extended light source 700A, first install the S-type lens module 400, then put the first extended light source 700A on the S-type lens module 400, insert the male buckle on the first side of the first extended light source base 733 into the female buckle on the first side of the S-type lens mounting cover 200, and align the first interface connection structure 720, that is, the pingo spring pin, with the extended port adapter plate 640, then press the first extended light source 700A to achieve circuit conduction between the pingo spring pin and the extended port adapter plate 640, and finally connect the first extended light source base 733 and the second side of the S-type lens mounting cover 200 with screws.

[0159] The method of installing the C-type lens module 500 and the first extended light source 700A is the same as the steps of installing the S-type lens module 400 and the first extended light source 700A. Figure 1c to Figure 1e , Figure 2b to Figure 2d As shown, the sizes of the first extended light source cover 732 required by the two are different. The first extended light source cover 732 adapted to the C-type lens module 500 is thicker and needs to be equipped separately, while the remaining components of the first extended light source 700A can be reused.

[0160] By applying the embodiments of the present application, the detachable connection between the first extended light source 700A and the S-type lens mounting cover 200 or the C-type lens mounting cover 300 is achieved through the above-mentioned method. In addition, the first extended light source 700A is modularly designed, and it only needs to connect the two ends to the lens mounting cover during installation, making the installation steps simple and convenient.

No additional cables are required, so that the structure of the industrial camera when the first extended light source 700A is installed is more compact.

[0165] In some embodiments of the present application, see Figure 1g , Figure 2e to Figure 2g , Figure 1g A three-dimensional structural diagram of an industrial camera provided in an embodiment of the present application when an S-shaped lens module and a second extended light source are installed; Figure 2e A three-dimensional structural diagram of an industrial camera provided in an embodiment of the present application when a C-type lens module and a second extended light source are installed; Figure 2f for Figure 2e A cross-sectional view of the industrial camera shown; Figure 2g for Figure 2e Exploded diagram of the industrial camera shown.

[0166] like Figure 1g , Figure 2e to Figure 2g As shown, the extended light source 700 is a second extended light source 700B.

[0167] The second extended light source 700B includes: a second extended light board 760 and a second interface connection structure 770 electrically connected to the second extended light board 760 .

[0168] The second interface connection structure 770 passes through the expansion port 801 and is detachably electrically connected to the expansion port adapter plate 640 .

The industrial camera can be matched with different light sources to meet the lighting needs of different working distances, thereby improving the user's usage selectivity.

[0171] In some embodiments of the present application, Figure 1g , Figure 2e to Figure 2g As shown, the second extended light board 760 is arranged relatively spaced apart from the light input end of the S-type lens module 400 or the C-type lens module 500; the second extended light board 760 is an annular light board, so that external light can pass through the through hole of the second extended light board 760 and enter the light input end of the S-type lens module 400 or the C-type lens module 500.

[0172] In the embodiment of the present application, the second extended light board 760 is arranged at a relative interval from the light-incoming end of the S-type lens module 400 or the C-type lens module 500, so that the industrial camera can be applied to the detection environment with a large working distance. The second extended light board 760 is a ring-shaped light board, so that the light on the object to be measured is more uniform, thereby making the lens imaging clearer.

[0173] In some embodiments of the present application, the second extended light source 700B further includes: an adjustment bracket 780 .

[0174] The adjustment bracket 780 is detachably connected to the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300 .

[0175] The second extended light board 760 is installed on the adjustment bracket 780 , and the adjustment bracket 780 can adjust the distance between the second extended light board 760 and the S-type lens module 400 or the C-type lens module 500 .

[0176] By applying the embodiment of the present application, the bracket 780 is adjusted to make the height of the second extended light board 760 adjustable, so that the industrial camera can adjust the height of the second extended light board 760 according to the working distance, that is, the distance from the second extended light board 760 to the object to be measured, thereby improving the measurement accuracy.

[0177] In some embodiments of the present application, Figure 1g , Figure 2e to Figure 2f As shown, the adjustment bracket 780 includes: a fixed plate 781 and a movable plate 782; the fixed plate 781 is detachably fixedly connected to the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300.

[0179] The movable plate 782 can drive the second extended light plate 760 to move toward or away from the S-type lens module 400 or the C-type lens module 500 relative to the fixed plate 781 .

[0180] Specifically, Figure 1g As shown, the fixed plate 781 and the movable plate 782 are both L-shaped plates, the vertical portion of the fixed plate 781 is connected to the S-type lens mounting cover 200 via threaded fasteners, the vertical portion of the fixed plate 781 is located on one side of the S-type lens module 400, and an opening is also provided at the location of the vertical portion of the fixed plate 781 corresponding to the expansion port 801, so that the first cable 771 of the second interface connection structure 770 passes through the fixed plate 781 and is electrically connected to the expansion port adapter plate 640.

[0181] The movable plate 782 and the horizontal part of the fixed plate 781 are slidably connected, which can be achieved through a slide rail or a gear rack transmission. The present application does not limit the specific method of the sliding connection.

[0182] The second extended light board 760 is installed on the vertical portion of the movable plate 782. The second extended light board 760 can move toward or away from the S-type lens module 400 or the C-type lens module 500 driven by the movable plate 782 to meet the lighting requirements of different working distances.

[0183] It should be noted that the above description of the horizontal and vertical parts is only for industrial cameras. Figure 1g The horizontal portion is the section where the fixed plate 781 and the movable plate 782 are perpendicular to the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300, and the vertical portion is the section parallel to the S-type lens mounting cover plate 200 or the C-type lens mounting cover plate 300.

[0184] In some embodiments of the present application, Figure 1g , Figure 2e to Figure 2f As shown, a strip groove 7811 is provided on the fixed plate 781. The movable plate 782 can be locked on the fixed plate 781 by cooperating with the strip groove 7811 through a locking screw 783.

[0185] The locking screw 783 passes through the movable plate 782 and the strip groove 7811. When loosened, it can play a guiding role, allowing the movable plate 782 to move along the strip groove 7811 to adjust the industrial camera to adapt to different working distances; when tightened, it can limit the movement of the movable plate 782 to avoid unclear imaging caused by the shaking of the movable plate 782.

[0186] In some embodiments of the present application, Figure 1g , Figure 2e to Figure 2g As shown, the second interface connection structure 770 includes: a first cable 771 and a second cable 772 .

As long as it is a standard SMR interface, it can be used as the second interface connection structure 770, which has high versatility.

[0190] General industrial light source connectors are SMR female connectors, while the plugs of the first cable 771 and the expansion port adapter plate 640 are SMR male connectors. Therefore, the first cable 771 can be connected to all standard industrial light sources, not only the ring light source shown in the embodiment of the present application, but also other industrial light sources such as strip light sources, linear light sources, point light sources, and surface light sources.

[0191] like Figure 1g and Figure 2e As shown, when installing the second extended light source 700B, first install the S-type lens module 400 or the C-type lens module 500, then fix the vertical part of the fixing plate 781 of the adjustment bracket 780 to the S-type lens mounting cover 200 or the C-type lens mounting cover 300, connect the pingo pin 7711 of the first cable 771 to the extension port adapter plate 640, and plug the SMR male connector 7712 into the SMR female connector 7721.

[0192] When the position of the second extended lamp board 760 needs to be adjusted, the locking screw 783 is loosened, the movable plate 782 is moved to a suitable position, and then the locking screw 783 is tightened.
