[0031] Embodiment:
[0032] Figure 1 is a schematic structural diagram of an engine detection device provided by an embodiment of the present utility model, as Figure 1 shown, the detection device includes a fence 1, a conveyor line 2 and a control component.
[0033] The fence 1 has an enclosed space 11, a vision light source camera 12 and a photoelectric sensor are arranged in the enclosed space 11, an inlet 13 and an outlet 14 are arranged on the fence 1, both ends of the conveyor line 2 penetrate through the inlet 13 and the outlet 14, the vision light source camera 12 is used to take pictures of the engine 100 on the conveyor line 2, and the photoelectric sensor is used to identify the engine 100 in the enclosed space 11.
[0034] The control component includes a door body 3, a driving member 4 and a controller. The door body 3 is located above the conveyor line 2, the driving member 4 is located on the fence 1, and the output end of the driving member 4 is in transmission connection with the door body 3 to drive the door body 3 to open and close the outlet 14. The photoelectric sensor, the controller and the driving member 4 are electrically connected in sequence, and the controller is electrically connected to the vision light source camera 12.
[0035] For an engine detection device provided by an embodiment of the utility model, when detecting an engine 100, each conveyor line 2 is sequentially conveyed from the upstream of the conveyor line 2 to the downstream (i.e., along the X-axis direction). Among them, each engine 100 will first enter the enclosed space 11 through the inlet 13. At this time, the photoelectric sensor will identify the engine 100 entering the enclosed space 11 and transmit the signal to the controller. The controller will control the drive member 4 to move so that the door body 3 moves and then closes, thereby completing the sealing of the outlet 14 (the sealing above the conveyor line 2). Thereafter, the controller will also control the visual light source camera 12 to start taking pictures of the engine 100. Since the door body 3 is closed, the corresponding light source of the visual light source camera 12 will not emit an area outside the enclosed space 11 during the photo detection process, thereby avoiding the eyes of the downstream staff from being irradiated, and thus avoiding damage. After the photo is completed, the controller will receive the control signal corresponding to the visual light source camera 12, and the controller will control the door body 3 to reopen so that the outlet 14 is opened, thereby ensuring that the engine 100 can be freely conveyed from the enclosed space 11 to the downstream through the conveyor line 2.
[0036] That is to say, in an engine detection device provided by an embodiment of the utility model, during the photo detection process, the corresponding light source of the visual light source camera 12 will not emit light outside the enclosed space 11, thereby preventing the eyes of downstream workers from being damaged by radiation.
[0037] In this embodiment, the detection device further includes a manipulator 7 , which is located in the enclosed space 11 , and an output end of the manipulator 7 is transmission-connected to the visual light source camera 12 to adjust the position of the visual light source camera 12 in the enclosed space 11 .
[0038] In the above embodiment, the manipulator 7 can drive the visual light source camera 12 to move and adjust the spatial position, so as to achieve multi-angle photography of the engine 100, further improving the accuracy of detection.
[0039] Exemplarily, the enclosed space 11 is provided with a support, and the manipulator 7 is arranged on the support.
[0040] Figure 2 Schematic diagram of the structure of the fixing frame provided by the embodiment of the utility model. Figure 2 As shown, the detection device further comprises a fixing frame 6, which is fixed on the fence 1, and the fixing frame 6 is located at the exit 14, and the driving member 4 is located on the fixing frame 6. The fixing frame 6 facilitates the installation of the driving member 4.
[0041] In one implementation of the utility model, the driving member 4 includes a cylinder 41 and a three-position five-way solenoid valve 42, the door body 3 is hinged on the side of the outlet 14 of the fence 1, the cylinder body of the cylinder 41 is hinged on the fence 1, the piston rod of the cylinder 41 is transmission-connected to the door body 3 to drive the door body 3 to switch the outlet 14, the controller and the three-position five-way solenoid valve 42 are electrically connected, the air inlet a of the three-position five-way solenoid valve 42 is used to communicate with the air source, the first air outlet e and the second air outlet d of the three-position five-way solenoid valve 42 are both connected to the atmosphere, the first working air port c of the three-position five-way solenoid valve 42 is connected to the rod chamber of the cylinder 41, and the second working air port b of the three-position five-way solenoid valve 42 is connected to the rodless chamber of the cylinder 41 (see Figure 3 ).
[0042] In the above embodiment, when the valve core of the three-position five-way solenoid valve 42 moves to the left position, the gas discharged from the gas source passes through the air inlet a of the three-position five-way solenoid valve 42, the second working air port b and the rodless chamber of the cylinder 41 in sequence, thereby pushing the piston rod outward. The gas in the rod chamber of the cylinder 41 will pass through the first working air port c and be discharged through the first air outlet e, so that the door body 3 can be closed, thereby achieving the sealing of the outlet 14.
[0043] Similarly, when the valve core of the three-position five-way solenoid valve 42 moves to the right position, the gas discharged from the gas source passes through the air inlet a of the three-position five-way solenoid valve 42, the first working air port c and the rod chamber of the cylinder 41 in sequence, thereby pushing the piston rod to retract inward. The gas in the rodless chamber of the cylinder 41 will pass through the second working air port b and be discharged through the second air outlet d, so that the door body 3 can be opened, thereby ensuring that the engine 100 can flow freely out of the outlet 14. In addition, when the valve core of the three-position five-way solenoid valve 42 does not move to the right position normally or there is an abnormal situation such as leakage, the valve core will remain in the middle position at this time, and the cylinder 41 will have no effect on the door body 3 at this time, which can ensure that the door body 3 can be smoothly opened under the push-up action of the engine 100 even if it is not opened by the action of the cylinder 41, and no obstruction will be formed.
[0044] That is to say, through the cooperation of the cylinder 41 and the three-position five-way solenoid valve 42, not only can the door body 3 be opened and closed conveniently, but it can also ensure that the door body 3 can be opened under the pushing action of the engine 100 even if it is not opened by the cylinder 41.
[0045] Exemplarily, the cylinder 41 is located on the fixing frame 6 .
[0046] Furthermore, there are two door bodies 3 and two cylinders 41, and the two door bodies 3 and the two cylinders 41 are symmetrically arranged along the outlet 14. The first working air port c of the three-position five-way solenoid valve 42 is connected to the rod cavity of each cylinder 41, and the second working air port b of the three-position five-way solenoid valve 42 is connected to the rodless cavity of each cylinder 41.
[0047] It is easy to understand that the cooperation of the two door bodies 3 and the two cylinders 41 can realize the opening of the left and right sides of the outlet 14 respectively, avoiding the problem of the door body 3 being too large and the cylinder 41 having too large a stroke.
[0048] Exemplarily, the first working gas port c and the second working gas port b may both be connected to the two cylinders 41 by using a one-to-two joint.
[0049] In this embodiment, the first gas outlet e and the second gas outlet d of the three-position five-way solenoid valve 42 are both provided with a muffler 43 to prevent excessive noise when gas is discharged from the three-position five-way solenoid valve 42 .
[0050] In addition, the air inlet of the three-position five-way solenoid valve 42 is provided with a switch deceleration pressure regulating valve 44. The switch deceleration pressure regulating valve 44 can not only play the role of switching the air circuit and regulating the air pressure, but also adjust the moving speed of the piston rod of the cylinder 41.
[0051] Exemplarily, two in-place detection switches 63 are provided on the fixed frame 6, one of which is used to detect the open state of the door body 3, and the other is used to detect the closed state of the door body 3. The two in-place detection switches 63 are electrically connected to the switch deceleration pressure regulating valve 44, so as to realize the switch control of the air circuit by identifying the switch state of the door body 3.
[0052] Continue to see Figure 2 A swing arm 5 is provided on the door body 3 , one end of the swing arm 5 is hinged on the side of the outlet 14 of the fence 1 , and the piston rod of the cylinder 41 is transmission-connected to the swing arm 5 .
[0053] In the above embodiment, the swing arm 5 supports the door body 3 .
[0054] Exemplarily, the swing arm 5 is hinged on the fixing frame 6 .
[0055] Exemplarily, the door body 3 is an elastic structure, which can prevent the engine 100 from being damaged by hitting the door body 3 in abnormal situations. The door body 3 can be a soft rubber structure.
[0056] In addition, a protective plate 61 is provided on the other side of the fixing frame 6, and the fixing frame 6 is located between the protective plate 61 and the door body 3, so as to protect the rotation space of the door body 3. A limit plate 62 is also provided on the fixing frame 6, which can block and limit the door body 3 when it is opened, so as to prevent the door body 3 from opening too far.
[0057] In another implementation of this embodiment, the driving member 4 may also be a linear module. The linear module can be used to achieve the lateral movement of the door body 3, thereby also achieving the closing and opening of the outlet 14.
[0058] It should be noted that in other embodiments of the present utility model, the driving member 4 can also be a motor, and the rotation of the motor drives the rotation of the door body 3, thereby realizing the state switching of the door body 3. The present utility model does not limit this.
[0059] Those skilled in the art can easily understand that the above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
