Description

Testing device

The present invention relates to a detecting device, and more particularly to a detecting device for inspecting the position of a decorative piece after it is decorated on a workpiece.

At present, there are more and more decorative parts on the shell of electronic products, especially regarding the ring-shaped decorative parts, such as the ring on the periphery of the camera on the electronic product, the ring is generally engraved with text, and the text is used by the words. The user knows the information such as the pixels of the camera, and the characters are generally arranged in a curved shape. However, these loops are prone to bias when placed, which affects the appearance of electronic products. These electronic products in which the ring is biased are defective products and need to be detected and removed. In the production of large-scale electronic products, the detection of such defective products is cumbersome, and the detection device is not easy to operate, and the detection effect is not satisfactory, and it is difficult to achieve a goal of balancing the production line and increasing production capacity.

In view of the above, it is necessary to provide a detecting device capable of quickly detecting the offset of the decorative part.

a detecting device for detecting a position of a decorative piece attached to a workpiece, the detecting device comprising a base and a pressing plate, wherein the pressing plate is provided with an alignment hole, and the workpiece is positioned on the base The pressing plate cooperates with the base and presses the workpiece, and observes a pattern on the decorative piece on the workpiece through the alignment hole to determine Decorative piece location.

Compared with the prior art, the detecting device can accurately determine whether the decorative member has a deviation position by placing the workpiece between the base and the pressing plate and observing the pattern of the decorative piece on the workpiece through the alignment hole on the pressing plate. The detecting device has the advantages of simple structure and convenient operation, and can quickly detect whether the decorative parts are placed in a wrong position.

1 is a schematic exploded view of a detecting device according to a preferred embodiment of the present invention; FIG. 2 is a schematic view of a cover of an electronic device with a decorative ring according to a preferred embodiment of the present invention; and FIG. 3 is a preferred embodiment of the present invention for detecting a deviation of the cover. FIG. 4 is a partially enlarged schematic view of a preferred embodiment of the present invention.

Referring to FIG. 1 , a detecting apparatus 100 according to a preferred embodiment of the present invention includes a base 10 and a pressure plate 20 .

The base 10 has a rectangular structure, and has a holding surface 11 . The holding surface 11 is provided with two protrusions 12 and four limiting blocks 14 . The bumps 12 have a square structure and protrude from the two sides of the holding surface 11 respectively. Each of the protrusions 12 protrudes from a positioning post 122, and the positioning post 122 is a cylinder for holding the pressing plate 20.

The four limiting blocks 14 are distributed in a rectangular shape on the holding surface 11 , and the height of the protruding portion is equivalent to the height of the protruding block 12 . An arcuate wall 142 is formed at one corner of each of the limiting blocks 14 , and each of the arcuate walls 142 is opposite to each other. The four arcuate walls 142 and the engaging surface 11 define an accommodating space 144 . The accommodating space 144 is configured to receive and position a housing of the electronic device.

The pressure plate 20 is a rectangular block having a pair of positioning holes 22 and two positioning holes 24 defined therein. The alignment hole 22 is defined between the two positioning holes 24 and has a trapezoidal shape and penetrates the pressure plate 20 . The two positioning holes 24 are circular holes respectively formed at two ends of the pressure plate 20 for engaging with the positioning post 122. The material of the pressure plate 20 can be made of a transparent polycarbonate (PC) material, and the bottom surface of the pressure plate 20 is coated with black paint 26 around the alignment hole 22.

Referring to FIG. 2 , an electronic device housing 30 includes a main body 32 and a lens assembly 34 . The lens assembly 34 is disposed on the main body 32. The lens assembly 34 includes a lens 342 and a decorative ring 344. The decorative ring 344 is disposed around the periphery of the lens 342 and surrounds the lens 342. The decorative ring 344 can be fixed by bonding. A pattern 3442 is formed on the decorative ring 344, and the pattern 3442 is distributed in an arc on the annular surface.

Referring to FIG. 3, when the detecting device 100 of the preferred embodiment of the present invention detects whether the decorative ring 344 of the electronic device housing 30 is deflected, the housing 30 is placed into the accommodating space 144, and the housing 30 passes through the four limits. The block 14 is positioned, and the height of the housing 30 is flush with the height of the bump 12 and the limiting block 14; then the pressing plate 20 is mounted on the base 10, and the positioning hole 24 of the pressing plate 20 is inserted into the convex portion. On the positioning post 122 of the block 12. At this time, the alignment hole 22 will align the pattern 3442 of the decorative ring 344. The operator observes the pattern 3442 on the decorative ring 344 by viewing the bit hole 22, and when the operator can fully see the pattern 3442 of the decorative ring 344, the decorative ring 344 is affixed, if only the decorative ring 344 is visible. When the partial pattern 3442 or the pattern 3442 is not visible at all, the decorative ring 344 is attached in an incorrect position, and the casing 30 can be considered to be a defective product.

The pressure plate 20 is made of polycarbonate material, which is favorable for the surface of the pressure plate to penetrate the pressure plate in the working environment. The bottom surface of the pressure plate 20 is coated with the black paint 26 to make it and the decoration. The pattern 3442 on the ring 344 is in sharp contrast, facilitating the operator to identify the position of the pattern 3442 of the decorative ring 344.

The detecting device 100 is disposed between the base 10 and the pressing plate 20, and is engaged with the positioning hole 24 of the pressing plate 20 through the positioning post 122 of the base 10 and through the alignment hole 24 and the housing on the pressing plate 20. The pattern 3442 of the decorative ring 344 on the 30 is aligned to determine whether the decorative ring 344 is deflected. The detecting device 100 has the advantages of simple structure, convenient operation and accurate judgment.
