Detailed Description

As shown in fig. 2 and 3, the assembling device of an embodiment of the present invention is used for assembling a combination meter. The combination meter includes a PCB board 2, a light guide holder 3, a dial 4, a front bezel (not shown), and a panel (not shown).

The assembling device comprises a controller (not shown) and a clamp 1, wherein a plurality of support columns 11 are arranged on the clamp 1 and used for supporting the assembled PCB 2 and the light guide support 3.

The fixture 1 is provided with a positioning column 6 corresponding to the invisible part of the dial plate 4 of the combination instrument and used for aligning the PCB 2, the light guide support 3 and the dial plate 4, the positioning column 6 is controlled by the controller to extend out during assembly, and the positioning column 6 is controlled by the controller to retract after assembly is completed.

The invisible part of the dial 4 is a part which is hidden from the driver after the assembly of the combination meter, i.e., after the front frame and the panel are mounted, and thus does not affect the appearance of the combination meter.

The assembling equipment further comprises a cylinder (not shown) connected with the positioning column 6 and a controller, and the controller controls the positioning column 6 to extend or retract through the cylinder.

The assembling device further comprises a detection unit connected with a controller, when the detection unit detects that the light guide support of the combination meter exists or does not exist on the clamp 1, the controller controls the positioning column 6 to extend or retract, and the detection unit can detect in different modes, such as a photoresistor or a piezoresistor.

In this embodiment, two positioning pillars 6 are provided, and in other embodiments, more than two positioning pillars, for example, 3 positioning pillars, may be provided.

As shown in fig. 4, the non-visible portion of the dial 4 is provided with two or more first positioning holes 42 corresponding to the positioning posts 6 of the assembling apparatus, and the corresponding positions of the PCB and the light guide holder are also provided with the first through holes 22 and the second through holes 32, as shown in fig. 6.

In this embodiment, the two first positioning holes 42 provided in the invisible part of the dial 4 are located at the two ends of the dial 4 in the length direction, so that the dial 4 can be positioned stably and accurately.

When the detection unit detects that the assembled PCB 2 and the light guide support 3 exist on the fixture 1, the controller controls the positioning column 6 to extend out, the positioning column 6 sequentially passes through the first through hole 22 and the second through hole 32, and the first positioning hole 42 of the dial 4 is aligned with the positioning column 6 for assembly, as shown in fig. 5 and 6 after the assembly is completed.

When the subassembly that the assembly was accomplished, including PCB board 2, leaded light support 3 and dial plate 4, take off the back from anchor clamps 1, detecting element detects that there are not PCB board 2 and leaded light support 3 assembled on anchor clamps 1, and the controller passes through cylinder control reference column 6 withdrawal.

The controller controls the positioning column 6 to automatically extend or retract, manual operation is avoided, the assembling efficiency of the combination instrument is improved, and the assembling precision is guaranteed.

In another embodiment, in order to prevent the assembling direction from being wrong, the cross section of the positioning part of the positioning column 6 is designed to be different in shape, and the positioning part refers to a part which passes through the first through hole 22 on the PCB board 2, the second through hole 32 on the light guide support 3 and the first positioning hole 42 on the dial 4 when assembling.

The cross-sectional shapes of the first through hole 22 on the PCB board 2, the second through hole 32 on the light guide holder 3, and the first positioning hole 42 on the dial 4 correspond to the cross-sectional shape of the positioning portion of the positioning post 6.

In this embodiment, the cross section of the positioning portion of the positioning column 6 located on one side of the fixture 1 is circular, and the cross sections of the corresponding first through hole 22, second through hole 32 and first positioning hole 42 are also circular; the cross section of the positioning part of the positioning column 6 on the other side of the fixture 1 is kidney-shaped, and the cross sections of the corresponding first through hole 22, second through hole 32 and first positioning hole 42 are kidney-shaped.

If at least one of the PCB board 2, the light guide support 3 or the dial 4 is reversely arranged, the positioning part (with a waist-shaped cross section) of the positioning column 6 on one side can not be inserted correspondingly, so that the error of the assembling direction can be prevented.

Of course, in other embodiments, other shapes are possible, as long as the PCB board and/or the light guide holder and/or the dial plate can be distinguished from each other.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited thereto. Various changes and modifications can be made by one skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention is to be determined by the appended claims.
