For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0020] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] This embodiment provides a printing circuit board transfer device, as shown in Figures 1 to 3 the figure, which includes: a workbench 1, a pushing mechanism 2, a suction mechanism 3, and a lifting mechanism 4; the pushing mechanism 2 is installed on the workbench 1 and reciprocally pushes the suction mechanism 3, the lifting mechanism 4, and the printing circuit board along the transfer direction; the lifting mechanism 4 is installed on the pushing mechanism 2 and drives the suction mechanism 3 to reciprocally move along the vertical direction; the suction mechanism 3 is installed on the lifting mechanism 4 and sucks the printing circuit boards placed at different positions on the workbench 1.

[0022] The suction mechanism 3 includes a support plate 5, support feet 6, suction cups 7, and a control pump 8; the support plate 5 is arranged on the lifting mechanism, the support feet 6 are installed in the through grooves with movable positions opened on the support plate 5, the suction cups 7 are installed on the support feet 6, the control pump 8 is installed on the workbench 1, and the suction cups 7 and the control pump 8 are connected through a pipeline. The control pump 8 absorbs air from the suction cups 7 through the pipeline. The pipeline is made of a flexible material and relies on the support feet 6 to move in the through grooves of the support plate 5. When it moves to a suitable position, the support feet 6 and the support plate 5 are locked with bolts, and when the suction cups 7 contact the printing circuit board, they can adsorb it; when the control pump 8 discharges air, the adsorption force of the suction cups 7 on the printing circuit board decreases, causing the printing circuit board to detach from the suction cups 7.

[0023] Adopting the above basic structure, the pushing mechanism 2 includes a slide rail 9, a slide seat 10, a limit seat 11, a pushing cylinder 12, and a connecting plate 13. The slide rail 9 is arranged on the workbench 1, the limit seat 11 is installed at one end of the slide rail 9, the slide seat 10 slides on the slide rail 9, the slide seat 10 is connected to the connecting plate 13, and the pushing cylinder is installed on the connecting plate 13.

[0024] The push cylinder 12 is welded on the connecting plate 13, the connecting plate 13 is fixed on the slide 10, the limit seat 11 is connected to the output end of the push cylinder 12, and the limit seat 11 is fixed to the processing table. When the push cylinder 12 is lifted, the output end of the push cylinder 12 pushes the slide 10 and the connecting plate 13 to slide on the slide rail 9, thereby driving the printed circuit board to move; when the push cylinder 12 retracts, the output end of the push cylinder 12 drives the slide 10 and the connecting plate 13 to reset and return to the initial position, and the printed circuit board is repeatedly moved automatically.

[0025] With the above basic structure, the lifting mechanism 4 includes a lifting cylinder 14 and a connecting frame 15 . The lifting cylinder 14 is arranged on the connecting plate 13 . The connecting frame 15 is connected to the output end of the lifting cylinder 14 . The connecting frame 15 is connected to the support plate 5 .

[0026] The connecting frame 15 is U-shaped, and its two ends are slidably matched with the connecting plate 13. The output end of the lifting cylinder 14 lifts and retracts the connecting frame 15, and the connecting frame 15 fixed on the support plate 5 realizes reciprocating motion in the vertical direction. With the above-mentioned basic structure, the support plate 5 is U-shaped, and the through groove is a closed waist shape. The support leg 6 moves in the through groove in an inclined direction, and the support leg 6 passes through the support plate 5 and is locked by bolts.

[0027] With the above basic structure, a transmission mechanism for printed circuit boards is also installed on the output end of the push mechanism 2. The transmission mechanism includes a plurality of transmission rollers, a control motor and a transmission belt. The plurality of transmission rollers are arranged in parallel, the control motor is connected to any transmission roller, and the transmission belt drives the transmission of the plurality of transmission rollers.

[0028] With the above basic structure, a guide rod 16 is further provided at the bottom of the push mechanism 2, and the guide rod 16 is installed on the processing table. The slide 10 at the bottom of the push mechanism 2 is guided by the guide rod 16, which improves the stability of the push mechanism 2 during the transmission process.

[0029] Working principle: The printed circuit board is placed on the workbench 1, and the pushing mechanism 2, the adsorption mechanism 3 and the lifting mechanism 4 cooperate with each other to transfer the printed circuit board to the other end. First, the lifting cylinder 14 on the lifting mechanism 4 pushes the support plate 5 connected to the connecting frame 15 and the connecting piece. The feet 6 and the suction cups 7 compare the printed circuit board. Manually adjust and move the feet 6 in the through slots on the support plate 5 to an appropriate position to prevent the suction cups 7 from falling into the soldering holes when adsorbing the printed circuit board, resulting in air leakage. The suction cups 7 adsorb the printed circuit board, and the lifting cylinder 14 retracts and lifts the adsorbed printed circuit board; Second, the pushing cylinder 12 in the pushing mechanism 2 pushes the support plate 5 and the adsorbed printed circuit board in the transmission direction. When reaching the designated position, the lifting cylinder 14 pushes the adsorbed printed circuit board down to the surface of the workbench 1. At the same time, the pump 8 is controlled to deflate the suction cups 7, and the adsorbed printed circuit board falls off the suction cups 7 and is transmitted along the printed circuit board transmission mechanism; Subsequently, the pushing mechanism 2 retracts to the initial position, and the pushing mechanism 2, the adsorption mechanism 3 and the lifting mechanism 4 repeat the above steps to transmit in turn.

[0030] During the transmission process, the suction cups 7 and the feet 6 can be adjusted according to the position of the through slots to avoid contact with the soldering holes when adsorbing the printed circuit board, ensure the stable adsorption of the printed circuit board by the suction cups 7, and prevent the printed circuit board from falling and being damaged during the transmission process.

[0031] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
