Description

Technical Field

[0001] The embodiments of the present invention relate to the field of detection technology, and in particular to an anti-mistaken entry detection device and material assembly equipment. Background Art

[0002] Before the finished top cover trolley is pushed into the automatic equipment with a grating, the Anton pull rope needs to be pulled down to close the grating. After the finished top cover trolley is pushed in and placed, the Anton pull rope needs to be pulled down again to restore the grating shielding to prevent others from entering by mistake and causing danger. At this stage, due to the automation transformation of the transportation of finished top covers, the grating needs to be automatically opened and closed when the trolley enters and exits the automatic equipment to avoid the risk of people entering by mistake.

[0003] Since the trolley is a third-party device as a transportation equipment, it cannot directly communicate with the automatic equipment. Under normal circumstances, when the trolley is about 20CM away from the light barrier, the light barrier will automatically open and close to prevent people from accidentally entering. However, when the trolley passes through the light barrier, the signal of the light barrier is shielded. At this time, if a person follows the trolley through the light barrier, the light barrier will not be able to detect that the person has entered the dangerous area, and there is a detection loophole.

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0036] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present invention are used to distinguish different objects, rather than to limit a specific order. The following embodiments of the present invention can be implemented separately, or in combination with each other, and the embodiments of the present invention do not specifically limit this.

[0037] Figure 1 It is a top view of an anti-mistaken entry detection device provided by an embodiment of the present invention. Figure 2 It is a schematic diagram of a first detection device provided in an embodiment of the present invention. Figure 3 It is a schematic diagram of a second detection device provided in an embodiment of the present invention.

[0038] like Figure 1-Figure 3 As shown, the anti-mistaken entry detection device is applied to the detection channel 20 of the material assembly area 10, and the automatic guided vehicle 30 (AGV) carries the material 31 through the detection channel 20 to enter the material assembly area 10; the detection device includes a first detection device 41 and a second detection device 42. The first detection device 41 is arranged at the channel entrance of the detection channel 20, and the second detection device 42 is arranged at the junction of the channel exit of the detection channel 20 and the material assembly area 10.

[0039] The detection light emitted by the first detection device 41 is in an "X" shape, and the detection light emitted by the second detection device 42 is in an "eight" shape or a "human" shape.

[0040] The first detection device 41 and the second detection device 42 are both used to detect that the light is interrupted twice in succession within a preset time period, and then send an alarm signal to the alarm device.

[0041] Specifically, when the automated guided vehicle 30 carrying the material 31 enters the material assembly area 10 through the detection channel 20, if a person follows the automated guided vehicle 30 in, and the person pushes the cart at the rear end of the automated guided vehicle 30, the "X"-shaped detection light emitted by the first detection device 41 is cut off after detecting the automated guided vehicle 30. Since the "X"-shaped detection light is not dense and is a single light, the "X"-shaped detection light will be restored in a short time at the arm of the person holding the automated guided vehicle 30, and then the person continues to move forward. The "X"-shaped detection light is cut off again due to the detection of the person's body again. The detection light is cut off twice within the preset time period, indicating that a person follows the automated guided vehicle 30 in. At this time, the alarm device will issue an alarm to prompt that a person has mistakenly entered.

[0042] If a person follows the automated guided vehicle 30 in, and the person's handcart walks on the side of the automated guided vehicle 30, the first detection device 41 detects that the automated guided vehicle 30 and the person are the same object passing by, and the "X"-shaped detection light will only be interrupted once, but when the automated guided vehicle 30 passes through the "eight"-shaped or "person"-shaped detection light emitted by the second detection device 42, it will be interrupted by the automated guided vehicle 30, and then the person continues to move forward. Due to the angle of light emission, the detection light will return to its original state at the arm of the person walking on the side, and then be interrupted again when the person's body is detected. The detection light is interrupted twice within the preset time period, indicating that a person follows the automated guided vehicle 30 in. At this time, the alarm device will sound an alarm to prompt that a person has mistakenly entered.

[0043] At this point, the first detection device 41 and the second detection device 42 cooperate with each other, and no matter whether a person walks behind or on the side of the automated guided vehicle 30, they can be detected without blind spots, effectively preventing people from entering by mistake.

[0044] The present application solves the technical problem in the prior art that when automatic handling equipment carrying materials enters the material assembly area, the grating automatically closes, making it impossible to detect people who accidentally enter the material assembly area, by adding two detection devices, which respectively emit "X"-shaped and "eight"-shaped or "human"-shaped light to detect the equipment entering the material assembly area. This achieves the technical effect of avoiding detection blind spots and effectively preventing people from accidentally entering.

[0045] Alternatively, if Figure 1-Figure 3 As shown, the detection device further includes a photoelectric detection device 43; the photoelectric detection device 43 is arranged between the first detection device 41 and the second detection device 42; the photoelectric detection device 43 uses a grating to emit a plurality of detection light rays parallel to the ground.

[0046] Specifically, the photoelectric detection device 43 is used as a detection device for daily detection of the automatic guided vehicle 30 entering the material assembly area 10. When the automatic guided vehicle 30 is detected to enter, the grating will be automatically closed. At this time, if a person follows the automatic guided vehicle 30 by hand to enter, it cannot effectively prevent the person from mistakenly entering. Therefore, it is necessary to cooperate with the above-mentioned first detection device 41 and the second detection device 42 to realize the function of preventing people from mistakenly entering.

[0047] Optionally, the detection device further includes an alarm device ( Figure 1-Figure 3 The alarm device is electrically connected to the first detection device 41, the second detection device 42, and the photoelectric detection device 43 respectively;

[0048] The alarm device is used to issue an alarm prompt when any one of the first detection device 41, the second detection device 42, and the photoelectric detection device 43 detects that there is a wrong entry situation.

[0049] Specifically, if a person mistakenly enters the material assembly area 10 when there is no automated guided vehicle 30 entering, the detection light emitted by the first detection device 41 will only be intercepted once by the person and will not cause an alarm. However, when continuing to move forward, the photoelectric detection device 43 will detect that a person has mistakenly entered, and at this time an alarm signal will be sent to the alarm device, which will issue an alarm prompt based on the alarm signal.

[0050] If an automated guided vehicle 30 enters and a person walks behind the automated guided vehicle 30, the detection light emitted by the first detection device 41 is interrupted twice within a preset time period, and the first detection device 41 sends an alarm signal to the alarm device, which makes an alarm prompt based on the alarm signal; if a person walks on the side of the automated guided vehicle 30, the detection light emitted by the second detection device 42 is interrupted twice within a preset time period, and the second detection device 42 sends an alarm signal to the alarm device, which makes an alarm prompt based on the alarm signal.

[0051] Optionally, the detection light emitted by the first detection device 41 and the second detection device 42 is infrared light.

[0052] Specifically, the detection light emitted by the first detection device 41 and the second detection device 42 is set to be infrared light, which is low-cost and can effectively prevent the light from causing personal injury to personnel.

[0053] Alternatively, if Figure 2 and Figure 3 As shown, the detection device also includes a door-type bracket assembly 50;

[0054] The door-type bracket assembly 50 is disposed at the detection channel 20 and is used to install the first detection device 41 , the second detection device 42 and the photoelectric detection device 43 .

[0055] Alternatively, if Figure 2 As shown, the first detection device 41 includes two infrared light generators and two infrared light receivers;

[0056] Two infrared light generators are respectively arranged at the top ends of both sides of the gate-shaped bracket assembly 50 at the channel entrance of the detection channel 20; two infrared light receivers are respectively arranged at the bottom ends of both sides of the gate-shaped bracket assembly 50 at the channel entrance of the detection channel 20;

[0057] One detection light beam emitted by an infrared light generator is received by one corresponding infrared light receiver, and the two groups of detection lights are in an "X" shape.

[0058] Specifically, see Figure 2 , an infrared light generator corresponds to an infrared light receiver diagonally opposite to it. When the infrared light receiver can receive the infrared light emitted by the corresponding infrared light generator, it indicates that no automatic guided vehicle 30 has passed by, or no person has passed by; when the infrared light receiver cannot receive the infrared light emitted by the corresponding infrared light generator, it indicates that an automatic guided vehicle 30 has passed by and blocked the infrared light. If it is blocked twice in a preset time, it indicates that a person has followed the automatic guided vehicle in, and the alarm device will issue an alarm prompt.

[0059] Alternatively, if Figure 3 As shown, the second detection device 42 includes two infrared light generators and two infrared light receivers;

[0060] Two infrared light generators are respectively arranged at the top of the upper side of the gate-type bracket assembly 50 at the junction of the channel outlet of the detection channel 20 and the material assembly area 10; two infrared light receivers are respectively arranged at the bottom ends of both sides of the gate-type bracket assembly 50 at the junction of the channel outlet of the detection channel 20 and the material assembly area 10;

[0061] One detection light beam emitted by an infrared light generator corresponds to one infrared light receiver, and the two groups of detection lights are in the shape of an "eight" or a "human".

[0062] Specifically, see Figure 3 , an infrared light generator corresponds to an infrared light receiver on the same side. When the infrared light receiver can receive the infrared light emitted by the corresponding infrared light generator, it indicates that no automatic guided vehicle 30 has passed by, or no person has passed by; when the infrared light receiver cannot receive the infrared light emitted by the corresponding infrared light generator, it indicates that an automatic guided vehicle 30 has passed by and blocked the infrared light. If it is blocked twice in a preset time, it indicates that a person has followed the automatic guided vehicle 30 in, and the alarm device will issue an alarm prompt.

[0063] An embodiment of the present invention further provides a material assembly device, which includes the anti-mistaken entry detection device and the mechanical arm in any of the above embodiments;

[0064] The anti-mistaken entry detection device is arranged at the detection channel entering the material assembly area to prevent people from entering the material assembly area; the robotic arm is arranged in the material assembly area to grab materials.

[0065] Optionally, the material assembly equipment further comprises a scheduling system and at least one automatic guided vehicle;

[0066] The automatic guided vehicle is used to carry materials through the inspection channel and enter the material assembly area under the control of the scheduling system.

[0067] Optionally, the automated guided vehicle includes a communication device; the automated guided vehicle achieves communication connection with the dispatching system via the communication device.

[0068] Specifically, a PLC (Programmable Logic Controller) is provided in the scheduling system of the material assembly equipment. When an automated guided vehicle is needed to transport materials to the material assembly area, the automated guided vehicle will send a task initiation instruction to the warehouse control system (WCS) through a communication device. The warehouse control system sends a scheduling instruction to the robot control system (RCS) based on the task initiation instruction. The robot control system sends a control instruction to the PLC based on the scheduling instruction. The PLC controls the automated guided vehicle to move to the material assembly area through the communication device in the automated guided vehicle.

[0069] When the AGV moves to the entrance of the inspection channel of the material assembly area, it first passes through the first inspection device. When passing through the first inspection device, the switch of the photoelectric inspection device is triggered, and the PLC in the dispatching system controls the grating of the photoelectric inspection device to close based on the trigger signal. When all the AGVs pass through the second inspection device, the switch of the photoelectric inspection device is triggered again, and the PLC in the dispatching system controls the grating of the photoelectric inspection device to open based on the trigger signal.

[0070] The material assembly equipment provided in the embodiment of the present invention includes the anti-mistaken entry detection device in the above embodiment. Therefore, the material assembly equipment provided in the embodiment of the present invention also has the beneficial effects described in the above embodiment, which will not be described in detail here.
