DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 4 As shown, the utility model provides a technical solution for a handling device for PCB board processing: the handling device for PCB board processing includes a plurality of handling mechanisms 6, a load mounting plate 3 for carrying the handling mechanism 6, and a guide mechanism 1 for guiding the load mounting plate 3. The handling mechanism 6 has two handling modes, one of which is adsorption and the other is clamping;

[0019] A connecting mechanism 2 is provided between the guide mechanism 1 and the load mounting plate 3 for connection. The guide mechanism 1 includes two trusses arranged in parallel. The connecting mechanism 2 is a first connecting frame 21 and a second connecting frame 22 connected to each other. A linear motor and a synchronous belt are provided between the first connecting frame 21 and the two trusses for connection, respectively, to control the horizontal position of the load mounting plate 3 and the transport mechanism 6.

[0020] A driving mechanism 4 is provided on the load mounting plate 3, and the driving mechanism 4 includes a first driving motor 41 and a second driving motor 42, wherein the first driving motor 41 is installed on the second connecting frame 22, and a rack and a guide rail are provided at the connection between the first connecting frame 21 and the second connecting frame 22, and a slider embedded in the guide rail is provided on the second connecting frame 22, and a gear meshing with the rack is provided at the output end of the first driving motor 41, and the second connecting frame 22 and the load mounting plate 3 connected to the second connecting frame 22 can be controlled by rotating the gear. The driving mechanism 4 also includes a positive and negative threaded rod 43 that is transmission-connected to the second driving motor 42, and the positive and negative threaded rod 43 is mounted at the bottom of the load mounting plate 3, and the second driving motor 42 drives the positive and negative threaded rod 43 to rotate, and the two ends of the positive and negative threaded rod 43 are respectively connected to a hanging rod 5, and a plurality of conveying mechanisms 6 are evenly installed on the two hanging rods 5;

[0021] The transport mechanism 6 includes a cylinder 61, one side of which is provided with a connecting block 62 connected to the hanging rod 5, and the output end of the cylinder 61 is connected to an output rod 63. The output and input of the cylinder 61 can control the extension and retraction of the output rod 63, so that the cylinder 61 and the output rod 63 form a clamping mechanism. In addition, a suction cup 64 is also connected to the output rod 63.

[0022] In the production and processing of PCB boards, the handling steps of single-sided and double-sided boards and multi-layer boards can be solved by the handling mechanism 6. A single single-sided and double-sided board can be directly adsorbed and handled by the suction cup 64, and for multi-layer boards, after stacking, they can be clamped and handled by the clamping mechanism formed between the cylinder 61 and the output rod 63;

[0023] Specifically, the guiding mechanism 1 is set up between the material platform and the processing station, and the linear motor and the synchronous belt can drive the connecting mechanism 2, the load mounting plate 3 and the conveying mechanism 6 to move between the material platform and the station. It should be supplemented that the synchronous belt is installed on one of the trusses, and a servo motor for driving the synchronous belt to rotate is arranged on the top of the truss. A clamping plate is arranged between the first connecting frame 21 and the synchronous belt for connection. When the servo motor drives the synchronous belt to rotate, it cooperates with the linear motor to stably drive the movement of the connecting mechanism 2, the load mounting plate 3 and the conveying mechanism 6. When the conveying mechanism 6 is driven to move above the material platform, the driving mechanism 4 works. At this time, the treatment of single-layer boards and multi-layer boards is different. For the conveying of single-layer boards: the second driving motor 42 only needs to control the position of the two hanging rods 5 to be above the board, and the suction cups 64 on the hanging rods 5 are all above the board. At this time, the first driving motor 41 works to drive the second connecting frame 22, the load mounting plate 3 and several components installed on the load mounting plate 3 to sink, so that the suction cups 64 can be in contact with the PCB board below, and then the suction cup 64 absorbs the single board, the linear motor and the synchronous belt operate, and the absorbed single board is transported to the processing station; for the transportation of multi-layer boards: a predetermined number of multi-layer boards are pre-processed, separated from the stacked boards below, and then the second drive motor 42 works to drive the positive and negative screw rods 43 to rotate. The rotation of the positive and negative screw rods 43 controls the hanging rods 5 at both ends to move away from each other, so that the distance between the hanging rods 5 on both sides is greater than the size of the board. Then the first drive motor 41 controls the load mounting plate 3 to sink, and synchronously, the cylinder 61 drives the output rod 63 to open, forming an open clamping structure, and then the second drive motor 42 rotates to control the two sets of hanging rods 5 to approach each other, and make the open clamping structure connected to the multi-layer board, and then the cylinder 61 controls the output rod 63 to contract to clamp the multi-layer board, and then the first drive motor 41 controls the load mounting plate 3 to rise, and synchronously, the linear motor and the synchronous belt run to transport the clamped multi-layer board to the processing station.
