Detailed Description

The circuit board positioning table of the present utility model will be described in more detail below in conjunction with the schematic drawings, wherein preferred embodiments of the present utility model are shown, it being understood that one skilled in the art could modify the utility model described herein while still achieving the advantageous effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.

The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. Advantages and features of the utility model will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

As shown in fig. 1, the embodiment of the utility model provides a circuit board positioning table, which comprises a placement table 1, wherein mounting plates 2 are slidably mounted around the upper surface of the placement table 1, four synchronous driving assemblies 3 for driving the mounting plates 2 to synchronously close or expand are commonly connected, the synchronous driving assemblies 3 are mounted on the lower surface of the placement table 1, an opening bush 4 is mounted above the four mounting plates 2, a sliding rod 6 is placed in the opening bush 4, a locking bolt 5 for locking the opening bush 4 to limit the sliding rod 6 to move is mounted on the opening bush 4, a sliding rod 6 is arranged in the opening bush 4, and a clamping plate 7 is detachably mounted at one end of the sliding rod 6 close to the center of the placement table 1.

In this embodiment, through the setting of the mounting panel of four common connection synchronous drive assemblies, the cooperation is through the setting of the splint that opening bush and slide bar and mounting panel are connected, can realize fixing in the location before the welding to the circuit board of different models, and the commonality is good.

The specific application method of the circuit board positioning table provided by the embodiment comprises the following steps:

when the circuit board of one type is welded and another type is required to be replaced, the distance between each clamping plate 7 and the mounting plate 2 is adjusted according to the length-width ratio of the circuit board to be welded, so that the four clamping plates 7 can be guaranteed to abut against four sides of the circuit board after being close together (namely, the circuit board is guaranteed to be positioned and fixed).

When adjusting the distance between splint 7 and mounting panel 2, at first unscrew locking bolt 5 for opening bush 4 opening opens, can draw slide bar 6 at this moment, realizes the regulation of the distance between splint 7 and the mounting panel 2, and after the regulation was accomplished, locking bolt 5 was screwed once more, makes opening bush 4 inside wall and slide bar 6 lateral wall closely contradict, realizes the fixed of slide bar 6. And then the circuit board to be welded is arranged between the four clamping plates 7, and the four clamping plates 7 are driven to be close to clamp four sides of the circuit board by utilizing the synchronous driving assembly 3.

In the above process, in order to facilitate the adjustment of the distance between the clamping plate 7 and the mounting plate 2, a scale is arranged on the side wall of the sliding rod 6.
