[0002] PCB (Printed Circuit Board) is the carrier of electrical connection of electronic components. In industry, in order to realize mass production of PCB, multiple PCBs are generally made on one board, and then each PCB is milled and separated by PCB splitter. After cutting into individual PCB products, the individual PCB boards need to be placed in the product carrier in an orderly manner, waiting for the next step of processing.

[0003] In the traditional PCBA production process, the placement and transportation of the whole PCBA board after separation mainly rely on manpower. This method is not only inefficient, but also easily affected by human factors in high-precision operations.

[0004] However, the general circuit board picking and placing mechanisms on the market currently have relatively simple functions. For example, in the patent document with patent number CN202123297668.1 and the name "A circuit board suction-type shifting mechanism", a circuit board suction-type shifting mechanism is disclosed, including a grabbing component, a lifting component and a translation component; the grabbing component is fixedly connected to the lifting component, the lifting component is fixed on the translation component, the lifting component includes a first connecting plate and a lifting drive assembly, the lifting drive assembly is fixedly connected to the first connecting plate, and the first connecting plate is fixedly connected to the translation component; the grabbing component includes a suction cup assembly, a fixing frame and a second connecting plate, the upper end face of the suction cup assembly is fixedly connected to the fixing frame, the side of the fixing frame is fixed on the second connecting plate, and the second connecting plate is fixedly connected to the lifting drive assembly. Although this mechanism can realize the up, down, left and right movement of the circuit board, the efficiency of picking and placing is low, and it can only simply grab and put down the circuit board, and it cannot ensure that the circuit board is placed on the tray in the correct direction, and it cannot be used to adapt the automatic plate-placing process of the circuit board.

[0007] Furthermore, the lifting and translation module includes a vertically arranged linear slide, a supporting base plate is slidably sleeved on the linear slide, and the rotary drive is installed on the supporting base plate.

[0008] Furthermore, the negative pressure suction cup module includes a negative pressure suction head and a positioning frame, and a plurality of horizontal slide grooves are vertically penetrated on the positioning frame, and the negative pressure suction heads are slidably sleeved vertically downward in the horizontal slide grooves.

[0009] Furthermore, one end of a positioning arm is connected to the negative pressure suction head, and a bolt through hole is correspondingly opened at the other end of the positioning arm.

[0013] Furthermore, a positioning camera is installed vertically downward on the supporting substrate, and the positioning camera is electrically connected to the lifting and translation module and the rotation drive.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments.

[0028] like Figures 1 to 3 As shown, this embodiment provides a rotating, lifting and unloading mechanism for a circuit board tray placing machine, including a lifting and translation module 1, a vertically downward rotating drive 2 is arranged at the bottom of the lifting and translation module 1, a docking bracket 3 is coaxially connected to the bottom of the rotating drive 2, and four negative pressure suction cup modules 4 are symmetrically arranged at the bottom of the docking bracket 3.

[0029] In actual use, the lifting and translation module 1 moves to the top of the circuit board 9 after the board cutting is completed and descends, so that the negative pressure suction head 401 at the bottom of the negative pressure suction cup module 4 contacts and sucks up the circuit board 9, and then the lifting and translation module 1 grabs the circuit board 9 and moves it to the top of the tray (not marked in the figure) and descends, and according to the actual placement requirements, the rotation angle of the rotary drive 2 is set by the industrial computer to adjust the direction of the circuit board 9, so that the circuit board 9 can be placed in the tray in the correct direction. Since it is common knowledge in the art to use an industrial computer to set the stroke of the lifting and translation module 1 and the rotation angle of the rotary drive 2, and the improvement focus of this embodiment is how to achieve the orientation adjustment of the circuit board 9, it is no longer repeated how the lifting and translation module 1 and the rotary drive 2 use the industrial computer to control the stroke.

[0030] The lifting and translation module 1 includes a vertically arranged linear slide 101, on which a support base plate 5 is slidably sleeved, and the rotary drive 2 is mounted on the support base plate 5. Since the rotary drive 2 and the negative pressure suction cup module 4 and other mechanisms need to be mounted on the support base plate 5, the operating load on the lifting mechanism is relatively large, so a screw-driven linear slide 101 is used to ensure the operating stability of the equipment.

[0031] The negative pressure suction cup module 4 includes a negative pressure suction head 401 and a positioning frame 402. Four horizontal slide grooves 403 are vertically penetrated on the positioning frame 402. The negative pressure suction head 401 is slidably sleeved in each of the horizontal slide grooves 403. One end of a positioning arm 404 is connected to the negative pressure suction head 401. The other end of the positioning arm 404 is correspondingly provided with a bolt through hole 405. The bolt through hole 405 is correspondingly arranged below the horizontal slide groove 403. Positioning bolts (not shown in the figure) are correspondingly connected in series on the horizontal slide groove 403 and the bolt through hole 405.

[0032] In this embodiment, in order to correspond to the generally square circuit board 9, horizontal slide grooves 403 are provided on the four corners of the positioning frame 402 to install the negative pressure suction head 401. The design of the horizontal slide groove 403 and the bolt through hole 405 allows the installation position of the negative pressure suction head 401 to be flexibly adjusted according to the size of the circuit board 9, thereby improving the adaptability of the device.

[0033] The negative pressure suction cup module 4 includes a vertical downward lifting drive 406, which is fixed to the bottom of the docking bracket 3, and the front end of the lifting drive 406 is connected to the positioning frame 402. In addition to using the linear slide 101 for lifting, each negative pressure suction cup module 4 is equipped with an independent lifting drive 406 to avoid position interference when taking and placing different circuit boards 9 due to simultaneous lifting of multiple negative pressure suction cup modules 4.

[0034] The docking bracket 3 is fixedly provided with a sensing sheet 601, and a photoelectric sensor 6 is fixedly provided on the side of the sensing sheet 601, and the photoelectric sensor 6 is electrically connected to the rotary drive 2. The photoelectric sensor 6 can detect the number of rotations of the rotary drive 2 to prevent it from over-rotating.

[0035] The negative pressure suction cup module 4 is electrically connected to a negative pressure control panel 7, which is installed at the front end of the lifting and translation module 1. The negative pressure control panel 7 can adopt a digital pressure controller on the market (such as Hongchang HC-Y810B), so that the staff can adjust and monitor the operating status of the negative pressure suction cup module 4 as needed.

[0036] A positioning camera 8 is vertically mounted downward on the support base plate 5, and the positioning camera 8 is electrically connected to the lifting and translation module 1 and the rotation drive 2. The positioning camera 8 is used by the staff to monitor and calibrate the moving positions of the lifting and translation module 1 and the rotation drive 2, so that the staff can handle faults such as equipment operation deviation in a timely manner.

[0037] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
