[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0024] like Figure 1-2As shown, the utility model provides a PCB inspection machine for loading and unloading, including a frame 100, a detection component 200 and a material moving component 300. The frame 100 has a feed end 110, a first discharge end 120 and a second discharge end 130. The detection component 200 includes a detection member 210 fixedly arranged on the frame 100 and at least two supporting members 220. The at least two supporting members 220 are slidably connected to the frame 100 and can be alternately moved to a position facing the detection member 210. The material moving component 300 has a material moving end for grabbing and moving a PCB board, so as to drive the PCB board to move between the feed end 110, the supporting member 220, the first discharge end 120 and the second discharge end 130.

[0025] During implementation, the PCB board to be inspected is placed on the feed end 110, and the material moving component 300 grabs the PCB board to the carrier 220. The carrier 220 can be moved to a position facing the detection component 210, and the detection component 210 detects the PCB board. After the detection is completed, the material moving component 300 can move the qualified products and the defective products to the first discharge end 120 and the second discharge end 130 respectively, thereby completing the sorting function. At the same time, in the above process, every time a PCB board is detected, another carrier 220 can drive the PCB board to be inspected placed thereon to move to a position facing the detection component 210, which can realize the continuous detection function, save time, and improve the detection efficiency.

[0026] The frame 100 in this embodiment is a load-bearing structure, and its specific shape and size are determined according to actual needs. The frame 100 has a feed end 110 , a first discharge end 120 , and a second discharge end 130 .

[0027] In one embodiment, the feed end 110 is a feed conveyor belt, the first discharge end 120 is an OK conveyor belt, and the second discharge end 130 is an NG conveyor belt, wherein the OK conveyor belt is used to convey PCB boards detected as qualified products, and the NG conveyor belt is used to convey PCB boards detected as defective products.

[0028] Specifically, a baffle 111 is installed at the end position of the feed conveyor belt to prevent the conveyed PCB board from falling. The present embodiment also includes three sensors 140, one of which is installed at the end position of the feed conveyor belt. When the sensor 140 senses the PCB board, the feed conveyor belt stops. The other two sensors 140 are respectively installed at the head end positions of the OK conveyor belt and the NG conveyor belt. When the sensor 140 senses the PCB board, the OK conveyor belt or the NG conveyor belt starts to operate.

[0029] The detection assembly 200 in this embodiment includes a detection member 210 fixed on the frame 100 and at least two supporting members 220. The at least two supporting members 220 are slidably connected to the frame 100 and can be alternately moved to a position facing the detection member 210.

[0030] like Figure 5 As shown, in one embodiment, the detection member 210 includes a gantry 211, a camera 212 and an LED lamp 213. The gantry 211 is fixedly connected to the frame 100, and the camera 212 and the LED lamp 213 are both mounted on the gantry 211. The surface image of the PCB board is taken by the camera 212 and compared with the image in the database, so that the function of detecting the PCB board can be realized. It can be understood that visual detection of the PCB board is a technical means that can be thought of by those skilled in the art.

[0031] There are two cameras 212, and the detection member 210 includes two sliders 214, a slide rail 215, and two locking screws 216. The slide rail 215 is fixedly arranged on the gantry 211. The two cameras 212 are slidably connected to the slide rail 215 via the two sliders 214, and the free ends of the two locking screws 216 pass through the two sliders 214 and can abut against the gantry 211. The positions of the two cameras 212 can be adjusted by moving the slider 214, and the slider 214 can be locked at the current position by the provided locking screws 216.

[0032] Of course, in other embodiments, the detection member 210 may also use other forms of detection structures such as probes to implement the detection function of the PCB board, which will not be elaborated and described in detail here.

[0033] like Figure 3-4 As shown, in one embodiment, the carrier 220 includes a tray 221, a guide rail 222 and a driving member 223. The guide rail 222 and the driving member 223 are both fixedly arranged on the frame 100. The tray 221 is slidably connected to the guide rail 222. The output end of the driving member 223 is connected to the tray 221 to drive the tray 221 to slide.

[0034] Among them, the number of the supporting members 220 is two, and the two trays 221 are arranged in sequence in the vertical direction and slide in the horizontal direction. The bottom of both sides of the upper tray 221 are slidably connected to the rack 100 via two guide rails 222 respectively, and the bottom of the lower tray 221 is slidably connected to the rack 100 via the guide rails 222.

[0035] Of course, in other embodiments, the running directions of the two trays 221 can be perpendicular to each other, or an angle can be formed between them, and there is no limitation on this, as long as the two trays 221 can be alternately moved to a position facing the detection member 210 .

[0036] The driving member 223 includes a motor and a lead screw. The motor is fixedly connected to the frame 100 , the output end of the motor is connected to the lead screw, the lead screw is rotationally connected to the frame 100 , and the lead screw passes through a threaded sleeve arranged at the bottom of the tray 221 .

[0037] It is understandable that the top of the tray 221 is provided with a groove whose shape and size match the PCB board, so as to facilitate the positioning of the PCB board. At the same time, the driving member 223 can also be replaced by other forms of structures, such as a linear motor.

[0038] The material moving assembly 300 in this embodiment is a structure for driving the PCB board to move.

[0039] In one embodiment, the material moving assembly 300 includes a robot 310 and a suction piece 320 . The robot 310 is installed on the frame 100 . The execution end of the robot 310 is connected to the suction piece 320 . The suction piece 320 is used to suction the PCB board.

[0040] Due to the setting of the gantry 211, the manipulator 310 in this embodiment adopts a six-axis manipulator, which can cross the gantry 211 to perform grasping operations. Of course, other forms of motion structures can also be used to achieve the intention of the embodiment of the utility model.

[0041] The adsorbent 320 may be realized by a vacuum pump, a hose, a vacuum pipe and a suction cup connected in sequence.

[0042] like Figure 6 As shown, in order to adapt to PCB boards of different sizes, in another embodiment, the material moving assembly 300 includes a connecting plate 321 and a plurality of adjustment plates 322, the execution end of the manipulator 310 is connected to the connecting plate 321, the adsorption member 320 has a plurality of adsorption ends, and the plurality of adsorption ends are respectively connected to the plurality of adjustment plates 322, and the plurality of adjustment plates 322 are slidably and / or rotatably connected to the connecting plate 321.

[0043] Compared with the prior art: a PCB board to be inspected is placed on the feed end 110, the material moving component 300 grabs the PCB board onto the carrier 220, the carrier 220 can be moved to a position directly opposite to the detection component 210, the detection component 210 detects the PCB board, and after the detection is completed, the material moving component 300 can move qualified products and defective products to the first discharge end 120 and the second discharge end 130 respectively, thereby completing the sorting function. At the same time, in the above process, every time after a PCB board is detected, another carrier 220 can drive the PCB board to be inspected placed thereon to move to a position directly opposite to the detection component 210, so as to realize the continuous detection function, save time, and improve the detection efficiency.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
