The terminology used in the description of the utility model herein is only for the purpose of describing specific embodiments, and is not intended to limit the utility model.

Referring to shown in Fig. 1, a kind of vertical workbench that the utility model provides, the workbench is vertically set, promptly the drilling surface of the PCB circuit board installed on it is in vertical direction.

The workbench includes a workbench frame 1, a guide rail pair 2, a positioning and moving away from a stretching mechanism 4 and a splint mechanism 5, wherein the workbench frame 1 is a hollow structure, that is, it is a frame body composed of four frames, and its two opposite sides There are long steps and short steps symmetrically processed on the frame, and a pair of guide rail pairs 2 are respectively arranged on the long step surfaces. The guide rail pairs 2 are used for manual board width adjustment to adapt to changes in the size of the PCB circuit board.

Between the two short steps on the workbench frame 1 and between the sliders of the two pairs of guide rail pairs 2, there is a positioning, moving away and stretching mechanism 4, which can be manually moved left and right by adjusting the position of the slider on the guide rail pair 2. Set the positioning and moving away from the stretching mechanism 4 to adapt to PCB circuit boards of different board widths, that is, the positioning moving away from the stretching mechanism 4 is used for positioning and clamping the PCB circuit board, that is, the actions of moving closer to positioning, stretching, and moving away can be realized . After adjustment, the slider is locked on the guide rail with the set screw 3.

The clamping plate mechanism 5 is arranged on the positioning, moving and stretching mechanism 4, which is used to press and fix the PCB circuit board, and its number can be increased or decreased according to actual needs. In this embodiment, five sets of splint mechanisms 5 are arranged in parallel.

As shown in accompanying drawing 2, described positioning moves away from stretching mechanism 4 and comprises positioning plate 41, moving bracket 42, pushing cylinder 43, cylinder push plate 44 and push plate guide rail pair 45, wherein the moving bracket 42 is provided with pushing cylinder 43 And push plate guide rail pair 45, the quantity of both can be increased or decreased according to actual needs, and in the present embodiment, both adopt two groups of symmetrical settings. One side of the positioning plate 41 is processed with a step as a PCB circuit board positioning surface 46 , and its opposite side is installed on the slider of the push plate guide rail pair 45 . The cylinder push plate 44 is installed on the positioning plate 41 and is connected with the moving cylinder 43, that is, the positioning plate 41 can move back and forth under the promotion of the moving cylinder 43 by the cylinder pushing plate 44.

The positioning and moving away from the stretching mechanism 4 is set on the short step surface of the workbench frame 1 or the slider of the guide rail pair 2 through the moving bracket 42, that is, one set of positioning and moving away from the stretching mechanism 4 is set on the workbench frame through the moving bracket 42 On the short step surface of 1, another group of positioning and moving away from the stretching mechanism 4 is set on the slide block of the guide rail pair 2 through the moving bracket 42.

In the above, the PCB circuit board positioning surface 46 is located in the middle section of the workbench frame 1. In this embodiment, the thickness of the workbench frame 1 is 66 mm, that is, the PCB circuit board positioning surface 46 is opposite to the two sides of the workbench frame 1 in the thickness direction. The distances are equal to 33mm and are strictly parallel to the Y axis. The positioning plate 41 can move 15mm under the promotion of the cylinder 43 by pushing the plate guide rail pair 45, so that the left and right sides of the PCB circuit board are provided with a 10mm wide positioning surface simultaneously. Or provide a 5mm wide unobstructed space at the same time on the left and right sides of the PCB circuit board to be removed after drilling.

As shown in accompanying drawing 3, splint mechanism 5 comprises splint cylinder 51, hinge fork 52, pressure plate bracket 53, fixed hinge seat 54 and movable hinge seat 55, wherein fixed hinge seat 54 is installed on the lower end surface of positioning plate 41, and press plate One end of both the bracket 53 and the movable hinge seat 55 is hinged to the two ends of the fixed hinge seat 54 , and the other ends pass through the positioning plate 41 respectively. Splint cylinder 51 is installed on the other end of movable hinge seat 55, and connects the middle part of pressing plate support 53 by hinge fork 52, and the end of pressing plate support 53 other ends corresponds to the position of PCB circuit board positioning surface 46 on positioning plate 41.

In the above, when the left and right sides of the inserted PCB circuit board are simultaneously positioned and moved away from the PCB circuit board positioning surface 46 of the stretching mechanism 4, the splint cylinder 51 of the splint mechanism 5 pushes the platen bracket 53 to clamp the PCB circuit board. When the left and right sides of the PCB circuit board to be taken away after positioning and moving away from the stretching mechanism 4 are provided with a 5mm wide unobstructed space at the same time, open the splint mechanism 5 and leave the outermost edge of the clamping plate bracket 53 of the splint mechanism 5 The left and right sides of the PCB board should be at least 5mm, so that the PCB board can be removed smoothly.

In order to avoid colliding with devices such as the laser head of the drilling rig when moving, the width of the positioning and moving away from the stretching mechanism 4 and the splint mechanism 5 is smaller than the thickness of the workbench frame 1 by 66mm when the PCB circuit board is clamped and running.
