DETAILED DESCRIPTION OF THE EMBODIMENTS
[0028] Refer to Figure 1As shown in the figure, the utility model provides a technical solution: a dust removal device for the surface of a PCB board that is convenient to move, including a general support 1. A wind box 3 is fixedly installed on the side wall of the general support 1. Four universal wheels 5 are installed below both the general support 1 and the wind box 3. An air duct 4 is connected between the wind box 3 and the general support 1. A conveying rack 2 is fixedly installed inside the general support 1. An adjusting device 6 is provided on the surface of the conveying rack 2. Support devices 7 are provided on the surfaces of both the wind box 3 and the general support 1.
[0029] The following specifically describes the specific settings and functions of its adjusting device 6 and support device 7.
[0030] Refer to Figures 1 - 3 As shown in the figure, in this embodiment: The adjusting device 6 includes two connecting blocks 603 fixedly connected to the surface of the conveying rack 2. A limiting frame 601 is fixedly installed between the two connecting blocks 603. Two limiting bars 604 are slidably connected inside the limiting frame 601. Two positioning blocks 606 are fixedly connected to the surface of the limiting frame 601. A lead screw 605 is threadedly connected inside the positioning block 606. The lead screw 605 is rotatably connected to the inside of the limiting bar 604. By rotating the lead screw 605, the driving work of the limiting bar 604 can be realized, which facilitates the accurate feeding work of stacked products of different sizes. The lower side of the limiting bar 604 is a bent structure. By setting the bent limiting bar 604, the feeding work of the PCB board between the two limiting bars 604 is facilitated, and the feeding efficiency of the PCB board is further improved. A rectangular block 607 is fixedly connected to the side wall of the limiting frame 601. A driving frame 608 is slidably connected inside the rectangular block 607. A driving rod 609 is threadedly connected inside the rectangular block 607. The driving rod 609 is rotatably connected to the inside of the driving frame 608. By rotating the driving rod 609, the driving rod 609 will drive the driving frame 608 to lift, which facilitates the transfer work of single PCB boards of different thickness sizes. Two balls 610 are embedded inside the driving frame 608. Two stop bars 602 are fixedly connected to the surface of the limiting frame 601. By setting the balls 610, the friction between the PCB board and the driving frame 608 during movement is reduced, thereby improving the conveying effect of the PCB board.
[0031] Refer to Figure 1 and Figure 4As shown in the figure, specifically, the support device 7 includes two mounting blocks 71 fixedly connected to the surfaces of the bellows 3 and the main bracket 1 respectively. A screw rod 73 is threadedly connected inside the mounting block 71. Rotating the screw rod 73 can achieve the support work for the corner positions of the dust removal device on the surface of the PCB board. A sliding pin 72 is slidably connected inside the mounting block 71. The lower end of the sliding pin 72 is fixedly connected to a support plate 74. The screw rod 73 and the support plate 74 are rotatably connected inside. The screw rod 73 drives the support plate 74 to move. The sliding of the sliding pin 72 inside the mounting block 71 plays a role in restricting the moving direction of the support plate 74. A number of silicone rings 75 are evenly glued to the side wall of the support plate 74. By arranging the silicone rings 75, the frictional force between the support plate 74 and the ground during support is increased.
[0032] Working principle: Place the stacked products at the position between the two limiting strips 604. The setting of the blocking strip 602 can achieve the blocking work for the stacked products. By rotating the lead screw 605, the driving work for the limiting strips 604 can be achieved, facilitating the accurate feeding work for stacked products of different sizes. Rotate the driving rod 609, and the driving rod 609 will drive the driving frame 608 to lift, facilitating the conveying work for single PCB boards of different thickness sizes. Start the conveyor belt, and the conveyor belt will drive the products at the bottom layer to be drawn out and conveyed from below the limiting frame 601, thus facilitating the one-by-one conveying work for the products. By setting the balls 610, the frictional force between the PCB board and the driving frame 608 during movement is reduced, thereby improving the conveying effect for the PCB board. By setting the limiting strips 604 with a bent structure, the feeding work for the PCB board between the two limiting strips 604 is facilitated, further improving the feeding efficiency for the PCB board. By setting the adjusting device 6, the one-by-one accurate feeding work for stacked PCB boards of different sizes using the dust removal device on the surface of the PCB board is facilitated, and to a certain extent, the dust removal efficiency for the PCB board is improved.
[0033] By setting the universal wheels 5, it facilitates the overall movement of the dust removal device for the PCB board surface. After moving the dust removal device for the PCB board surface to the required position, rotate the screw rod 73, and the screw rod 73 will drive the support plate 74 to move. Among them, the sliding pin 72 slides inside the mounting block 71 to play a role in restricting the moving direction of the support plate 74. At this time, the support work for the corner position of the dust removal device for the PCB board surface can be realized, and the use of the universal wheels 5 can be restricted, thus avoiding the movement work of the dust removal device for the PCB board surface, improving the flexibility of moving the dust removal device for the PCB board surface. By setting the arranged silica gel rings 75, the frictional force between the support plate 74 and the ground is increased, thereby further improving the stability of supporting the dust removal device for the PCB board surface. By setting the support device 7, it facilitates the flexible support work for the dust removal device for the PCB board surface, avoids the repeated movement of the dust removal device for the PCB board surface, and thus improves the flexibility of moving the dust removal device for the PCB board surface.
