[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further elaborates on the present invention in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Embodiment:

[0027] Reference Figures 1-8The charger circuit board automatic assembly and detection equipment shown in the figure includes a frame, on which a first conveyor line 1, a second conveyor line 2 and a charger buckle pulling mechanism 5 are arranged, a first handling robot 3 is arranged next to the first conveyor line 1, and a second handling robot 4 is arranged next to the second conveyor line 2. A visual inspection mechanism 6 is arranged on the frame next to the charger buckle pulling mechanism 5. The charger buckle pulling mechanism 5 includes an XY moving module 501, an outer shell elastic positioning component 502, a pulling translation module 503, an offset cylinder 504 and a pulling hook plate 505. The outer shell elastic positioning component 502 is fixedly connected to the moving table of the XY moving module 501, and a tension sensor is fixedly connected to the moving table of the offset cylinder 504.

[0028] On the frame, beside the first conveyor line 1 and the second conveyor line 2, there are arranged a push-unlocking cylinder capable of positioning the circulating carrier, as well as an intermediate transfer vehicle for placing the charger shell or circuit board in transit, and a return line for recovering the empty carrier is arranged inside the frame. A blocking cylinder is fixedly connected to the frame below the first conveyor line 1 and the second conveyor line 2. The blocking cylinder is used to block the carrier in the conveying process, so that it stops at the loading station, and the positioned carrier is lifted by the lifting module. Subsequently, the clamping end of the carrier loaded with the charger shell and the carrier loaded with the circuit board is pushed by the push-unlocking cylinder to release and unlock (there is an elastic clamping structure on the above-mentioned carrier, and after the product is placed on the carrier, the elastic clamping structure is in a clamping state to clamp the product), which is convenient for subsequent robot transfer. The blocking cylinder and the conveyor belt are misaligned to prevent the conveyor belt from interfering with the lifting and lowering action of the blocking cylinder piston rod.

[0029] The frame is fixedly connected to the sides of the first conveyor line 1 and the second conveyor line 2 with a scanning mechanism, which includes a scanning translation module and a scanner. The scanner can scan the QR code on the carrier to prevent the wrong material from flowing into the production line. The scanner is fixedly connected to the mobile station of the scanning translation module, and the scanning translation module is fixedly connected to the frame. The scanning translation module is used to drive the scanner to translate.

[0030] The first handling robot 3 includes a first XYZ moving module and a first gripper cylinder, and the first XYZ moving module drives the first gripper cylinder to move and transport the charger shell. The second handling robot 4 includes a second XYZ moving module, a rotating device and a second gripper cylinder, and the second XYZ moving module is used to drive the second gripper cylinder to move and transport the circuit board workpiece, and the rotating device is used to adjust the installation angle before the circuit board is assembled. The pull hook plate 505 is fixedly connected to the detection end of the tension sensor. When the pull hook plate 505 pulls the buckle on the charger shell, the tension data is detected to prevent the pull hook plate 505 from over-pulling the buckle to cause irreversible deformation or buckle breakage.

[0031] The positioning seat 5022 of the housing elastic positioning component 502 is used to position and load the charger housing. When the main slider 5024 is not in contact with the baffle, under the action of the spring 5027, the second sliding chuck 5026 and the first sliding chuck 5023 are in a clamping state of the charger housing. When the XY moving module drives the base 5021 to translate and slide to the loading and unloading station, under the blocking of the baffle, the main slider 5024 slides in the reverse direction relative to the traveling direction of the base 5021. At this time, when the inclined slider 5025 slides in the limit groove, it will push the second sliding chuck 5026 to slide away from the positioning seat 5022, and the first sliding chuck 5026 loosens the clamp synchronously with the sliding of the main slider 5024. At this time, the charger housing can be loaded or unloaded.

[0032] The vision inspection mechanism 6 includes a side CCD camera, a lower CCD camera and an upper CCD camera, which can be from multiple angles. Both the side CCD camera and the lower CCD camera are fixedly connected to the frame, and the upper CCD camera is fixed on the second handling robot 4.

[0033] The working principle of the present invention is as follows: When the present invention is in use, the carriers loading the charger housing and the carriers loading the circuit boards are respectively conveyed and circulated through the first conveyor line 1 and the second conveyor line 2. At the loading station, the carrier at the loading station is vertically lifted by the lifting module. At this time, the XY moving module 501 drives the housing elastic positioning component 502 to the baffle to loosen the first sliding chuck 5023 and the second sliding chuck 5026. Then, the first handling robot 3 transports the charger housing to the transfer carrier. The second handling robot 4 moves the circuit board to directly above the lower CCD camera. Then, the first handling robot 3 transfers the charger housing to the positioning seat 5022. The XY moving module 501 drives the housing elastic positioning component 502 to move to the assembly station. At this time, under the action of the spring 5027, the first sliding chuck 5023 and the second sliding chuck 5026 tighten the charger housing. Then, the pulling and translating module 503 of the charger buckle pulling mechanism 5 drives the pulling hook plate 505 to translate above the charger housing. Then, the misaligned cylinder 504 drives the pulling hook plate 505 to descend to the inside of the buckle. The pulling and translating module 503 drives the pulling hook plate 505 to pull the buckle outwards, so that the buckle is misaligned with the slot for installing the circuit board. During this process, the side CCD camera takes pictures to detect the deformation angle of the buckle, and the lower CCD camera takes pictures of the circuit board. The rotation device drives the second jaw cylinder to rotate and finely adjust the angle of the circuit board. Then, the second handling robot 4 vertically inserts the adjusted circuit board into the corresponding slot of the charger housing. Then, the pulling hook plate 505 resets. Thus, the assembly of the circuit board is completed. The upper CCD camera performs vision inspection on the assembled finished product. Finally, the housing elastic positioning component 502 moves to the loading and unloading station. The first handling robot 4 transports the assembled product into the corresponding charger housing carrier and is conveyed through the first conveyor line 1 to the subsequent workstations for processing.
