The double telecentric lens has a larger field of view and a wider range, so that the wide-field range measurement can be realized. In addition, the flash equipment further comprises a plurality of light sources for illumination, and the first light source and the second light source are oppositely arranged on two sides of the bearing surface and can illuminate the workpiece comprehensively, so that the measurement mechanism can conveniently measure.

In some examples, the flash device may also be referred to as a "flash meter" or "gauge. In some examples, the flash device may be used in the fields of precision machinery, optical communication devices, precision molds, magnetic materials, precision stamping, cell phone precision accessories, medical instruments, clocks, cutters, metrology inspection, and the like.

Hereinafter, the flash device according to the present embodiment will be described in detail with reference to the drawings.

Fig. 1 is a schematic diagram showing a partial structure of a flash apparatus 1 according to an embodiment of the present invention. Fig. 2 is a schematic diagram illustrating the overall structure of the flash apparatus 1 according to the embodiment of the present invention. In some examples, fig. 2 may represent that the flash device in fig. 1 is provided with a second light source 21 (described later).

In the present embodiment, the flash apparatus 1 may include a carrying mechanism 10, a supporting mechanism 20, a measuring mechanism 30, and a plurality of light sources. In some examples, the carrier mechanism 10 may be used to carry a workpiece, the support mechanism 20 may be used to support the measurement mechanism 30, the measurement mechanism 30 may be used to measure a workpiece, and the plurality of light sources may illuminate a workpiece. In this case, it is possible to illuminate the workpiece placed on the carrier 10 by a plurality of light sources and measure the workpiece by the measuring mechanism 30 to obtain measurement information of the workpiece.

In some examples, the support mechanism 20 may be disposed on the carriage mechanism 10. In some examples, the support mechanism 20 may be generally cylindrical in shape.

In some examples, the support mechanism 10 may have a support surface that may be used for a workpiece.

In some examples, the measurement mechanism 30 may be provided to the support mechanism 20 (see fig. 1). That is, the support mechanism 20 may be fixed by the measurement mechanism 30. In some examples, one side of the support mechanism 20 may be slightly curved. In this case, the deformation that may be caused by carrying the measuring mechanism 30 can be reduced to some extent.

In some examples, the measurement mechanism 30 may be disposed opposite the carrier mechanism 10. This facilitates the measurement of the workpiece on the carrier mechanism 10 by the measuring mechanism 30.

In some examples, the measurement mechanism 30 may include a double telecentric lens 31. In some examples, the field of view of the double telecentric lens 31 is large, so when multiple workpieces are placed on the carriage 10, the double telecentric lens 31 can also perform multiple workpiece measurements simultaneously. In this case, the number of measurements can be reduced to some extent, whereby the efficiency of the measurement can be improved. In addition, the measurement accuracy of the double telecentric lens 31 is also high. Therefore, a more accurate measurement result can be obtained.

Generally speaking, the telecentric lens can filter most diffuse reflection light rays, receive parallel light rays and form dark images in a natural environment, so that the advantage of the double telecentric lens 31 can be exerted to a great extent by selecting a light source of the parallel light rays, and an object to be measured, such as a workpiece, has clear and stable edges. That is, when measurement is performed by the measurement mechanism 30, it is necessary to provide a good measurement environment for the double telecentric lens 31 based on a predetermined light source. In some examples, sufficient light and a wide range of parallel light may be provided by a preset light source. In the present embodiment, a plurality of light sources may be provided to assist the measurement mechanism 30 in performing measurement.

In some examples, the plurality of light sources may include a first light source 40 (described later) and a second light source 21. In some examples, the first light source 40 may be a collimated light source. The first light source 40 may provide a larger range of parallel light to the double telecentric lens 31. In some examples, the parallel light may be selected by a corresponding light path structure (described later in detail). In some examples, the optical path structure may be disposed below the carrier mechanism 10. Thereby, the first light source 40 may form parallel light entering the double telecentric lens 31 based on the optical path structure.

In some examples, because the measurement mechanism 30 is required to measure the orientation of a workpiece placed on the bearing surface, when the parallel light rays are perpendicular to the bearing surface, the parallel light rays at the workpiece location may be blocked when the measurement mechanism 30 is used to measure the workpiece. In this case, if the parallel light exits from below the workpiece, the profile of the workpiece can be made more prominent, and a better backlight environment is provided for the measurement by the measurement mechanism 30. Thus, measurement of the workpiece can be facilitated.

In some examples, the second light source 21 may be coaxial with the double telecentric lens 31 when the second light source 21 is in operation. When a coaxial light source is used, part of light rays are reflected by the workpiece and then enter the measuring mechanism 30 (the double telecentric lens 31), so that the measuring mechanism 30 can form different light and shade areas when the workpiece is measured, and the local characteristics of the workpiece can be measured based on the corresponding areas. Thereby, the measurement of the respective characteristics can be facilitated. For example, surface inspection, scratch inspection, may be performed on the workpiece.

In some examples, the second light source 21 may be disposed on the support mechanism 20. In some examples, the second light source 21 may be movably disposed at the support mechanism 20. Thereby, the measurement can be facilitated.

In some examples, the second light source 21 may move up and down in a vertical direction. In this case, when the height of the workpiece is different, the position of the second light source 21 may be adjusted so that the second light source 21 illuminates the workpiece at a certain height. Meanwhile, workpieces are polished at different heights (different distances), so that different polishing states can be provided, and the measuring mechanism 30 can conveniently perform corresponding measurement.

In some examples, the second light source 21 may also rotate in a plane parallel to the bearing surface. In addition, when performing measurements for different characteristics, it is possible to select whether or not to operate the second light source 21. That is, when the second light source 21 is not required to be used, the possibility of blocking the measurement of the double telecentric lens 31 can be reduced by unscrewing the second light source 21.

In some examples, the first light source 40 and the second light source 21 may be disposed on opposite sides of the carrying surface, respectively. The first light source 40 may be used in combination with the second light source 21 to expose a workpiece. In some examples, exposure may also mean that the respective light sources illuminate the workpiece at a predetermined brightness.

In some examples, the plurality of light sources may further include a third light source. In some examples, the third light source may be disposed at a lens front end of the double telecentric lens 31. In some examples, the third light source may be an annular light source.

Fig. 3 is a first perspective view schematically showing a part of the mechanism of the flash apparatus 1 according to the embodiment of the present invention. Fig. 4 is a second perspective view schematically showing a part of the structure of the flash apparatus 1 according to the embodiment of the present invention. For ease of understanding, the positions of the double telecentric lens 31 and the carrier mechanism 10 are illustrated by fig. 3 and 4, and the first viewing angle and the second viewing angle are illustrated from different sides, respectively.

In some examples, light from first light source 40 may enter measuring mechanism 30 through the bearing surface. Referring to fig. 3 and 4, light emitted from the first light source 40 may enter the double telecentric lens 31 in the measuring mechanism 30 through the bearing surface. This can assist the double telecentric lens 31 in measurement.

In some examples, the double telecentric lens 31 may be spaced from the bearing surface by a predetermined distance. In this case, the double telecentric lens can measure the workpiece at a predetermined position. In addition, the parallel light beam is formed more uniformly as the path becomes longer. Thus, measurement can be performed relatively accurately based on the light distribution.

Fig. 5 is an optical path configuration diagram illustrating the first light source 40 according to the embodiment of the present invention. Fig. 6 is an ideal schematic diagram showing the light emitted from the first light source 40 according to the embodiment of the present invention. Fig. 7 is a schematic diagram showing the light path structure according to the embodiment of the present invention reflecting light.

In some examples, as shown in fig. 5, the first light source 40 may include a plurality of mirrors 42. In some examples, the first light source 40 may further include a light emitting unit 41. In some examples, the light emitting unit 41 may emit light, and the light may sequentially reach the plurality of mirrors 42, and the light reaches the plurality of mirrors 42 to be reflected a plurality of times to form parallel light.

In some examples, the first light source 40 emits a plurality of light beams, and the plurality of light beams may form parallel light.

In some examples, the light emitted from the light emitting unit 41 may be reflected via a plurality of lower mirrors 42. In some examples, the mirror faces of the plurality of mirrors 42 may be perpendicular to each other. In this case, when the light emitted from the light emitting unit 41 reaches the plurality of reflecting mirrors 42, the emitted light can be formed in parallel with the emitted light. In some examples, the ray direction of the parallel light may be adjusted. In this case, the rays of the parallel light may be adjusted to obtain the desired parallel light.

In some examples, this may be adjusted by the arrangement of the mirror 42. Preferably, the plurality of mirrors 42 may be perpendicular to each other. In this case, the direction of the parallel light rays may be perpendicular to the bearing surface, and the light rays emitted by the first light source 40 may be incident on the measuring mechanism 30 (i.e., the double telecentric lens 31) at right angles to the workpiece.

In some examples, it is desirable to obtain the desired parallel light through the schematic light path shown in fig. 6, however, in actual practice, the light emitted from the light emitting unit 41 is divergent and contains a large amount of undesired light. Based on the optical path structure, when light is reflected, more dispersed light may be processed to filter part of the undesired light as shown in fig. 7.

For ease of understanding, some undesired rays (more dispersed, non-uniform rays) are also distinguished in the figure, and the reflected undesired rays are indicated by dashed lines. It can also be seen in fig. 7 that after being reflected by the plurality of mirrors 42, part of the undesired light may escape out of the optical path structure, in which case the composition of the undesired light in the light may be reduced, thereby contributing to the formation of parallel light. Therefore, parallel light can be obtained through the light path structure.

In some examples, the first light source 40 may be disposed on one side of the carrying surface. In some examples, the first light source 40 may be disposed below the carrying surface. In other words, the light emitting unit 41 and the reflector may be disposed below the supporting surface. In some examples, after the light emitting unit 41 emits light, the light may be reflected by a plurality of mirrors 42 as shown in fig. 5 to filter undesired light and then form parallel light beams. The multiple parallel light beams reach the workpiece carried by the carrying surface through the carrying surface or enter the double telecentric lens 31.

In some examples, the light emitting unit 41 and the plurality of reflection mirrors 42 may be spaced apart by a long distance. In the present embodiment, the longer the distance that the light travels, the higher the accuracy with which the light is used for detection. In the present embodiment, as shown in fig. 3 or fig. 4, the double telecentric lens 31 may be disposed at the flash apparatus 1 at a certain distance from the bearing surface. Therefore, the light emitted by the first light source 40 can enter the double telecentric lens 31 after passing through a long distance.

In this embodiment, a large field of view is shot through the double telecentric lens 31, and when shooting is performed through the double telecentric lens 31, a certain light environment is formed by the first light source 40 and the second light source 21, so that the measurement accuracy of the flash device 1 can be effectively ensured when measuring a plurality of workpieces.

While the present invention has been described in detail in connection with the drawings and examples, it is to be understood that the above description is not intended to limit the invention in any way. Those skilled in the art can make modifications and variations to the present invention as needed without departing from the true spirit and scope of the invention, and such modifications and variations are intended to be within the scope of the invention.
