Technical Field
[0001] The utility model relates to a detection device, in particular to a 3D detection machine for shoe soles. Background Art
[0002] In general, in order to detect whether the manufacturing quality of the soles meets the standards, the various values of the appearance dimensions must be measured one by one manually to check whether they are within the acceptable range.

If there are multiple shoe types and sizes of soles, jigs corresponding to different shoe types and sizes must be prepared and then manually installed on the corresponding jigs, which is very inconvenient.

[0028] See also Figure 2 , Figure 3 , Figure 4 The machine unit 2 includes a base 21, a housing 22 disposed on the base 21, and a stopper 23 disposed on the base 21. The base 21 and the housing 22 together define a accommodating space 211, an inlet 212 and an outlet 213 spaced apart along a first direction X and connected to the accommodating space 211 and the outside, and a side opening 214 opened along a second direction Y and connected to the accommodating space 211 and the outside.

[0029] The conveying unit 3 is disposed on the base 21 and is used to convey the sole 7 along the first direction X. The conveying unit 3 passes through the inlet 212 and the outlet 213. In this embodiment, the conveying unit 3 is a conveyor belt. In other embodiments, other equivalent components that can convey the sole 7, such as a rotating worktable, etc., can also be selected, but the present invention is not limited thereto.
[0030] The detection unit 4 is arranged on the base 21 and located in the accommodating space 211, and includes two support frames 41 arranged on the base 21 at intervals along the first direction X and extending along an up-down direction Z, a first image capture group 42 for photographing the corresponding model mark 71, and a second image capture group 43 for photographing the corresponding sole 7. The first image capture group 42 is also used to output a model information for generating a first image, and the second image capture group 43 is also used to output a size information for generating a second image. The first image is related to the corresponding model mark 71, and the second image is related to the corresponding sole 7 as a whole, and can also be related to the corresponding designated area 72 of the sole 7. In more detail, the model information is a code for generating the first image, and the size information is a code and point cloud data for generating the second image. In this embodiment, the designated area 72 is a rectangular area on the top surface of the sole 7 corresponding to the forefoot part of the human foot. In other embodiments, other shapes and parts can also be selected according to detection requirements.
[0031] Specifically, the vertical direction Z is perpendicular to the first direction X and the second direction Y. The support frame 41 is located between the material inlet 212 and the side opening 214 in the first direction X. The first image capture group 42 is movably disposed on the support frame 41 adjacent to the material inlet 212. The second image capture group 43 is movably disposed on the support frame 41 adjacent to the side opening 214. The first image capture group 42 and the second image capture group 43 are located above the conveying unit 3 in the vertical direction Z. In this embodiment, the first image capture group 42 is a 2D image capture camera, and the first image capture group 43 is a 3D image capture camera. In other implementations, other equivalent components that can capture the first image and the second image may also be selected, without limitation.
[0032] The deflection unit 5 is disposed on the base 21 and is located in the accommodating space 211 and can be driven to deflect the sole 7 on the conveying unit 3 along the second direction Y. The deflection unit 5 includes a driving group 51 disposed on the base 21, and a pushing member 52 driven by the driving group 51 and movable along the second direction Y, and the pushing member 52 is used to push the sole 7. In more detail, in this embodiment, the driving group 51 is a pneumatic cylinder spanning above the conveying unit 3. In other embodiments, other equivalent components that can drive the pushing member 52, such as a cam group, etc., can also be selected. Other configuration methods can also be selected according to needs, but are not limited thereto.
[0033] The control unit 6 is signal-connected to the detection unit 4 and the deflection unit 5, and includes an operation panel 61 disposed on the housing 22 and operable, and pre-stores a plurality of standard size groups, each of which corresponds to a model mark 71. The control unit 6 is also used to receive the model information and the size information, and select the corresponding standard size group according to the model information, and calculate a detection size group related to the corresponding sole 7 according to each size information, and then determine whether the detection size group meets a detection condition related to the standard size group. When the detection condition is met, the control unit 6 further drives the deflection unit 5.
[0034] In the present embodiment, the standard size group has a standard length, a standard width, a first standard slope, and a second standard slope. The detection size group has a detection length in the first direction X and compared with the standard length, a detection width in the second direction Y and compared with the standard width, a first detection slope in the first direction X and compared with the first standard slope, and a second detection slope in the second direction Y and compared with the second standard slope. In other embodiments, other detection items, such as warpage, distortion, etc., can also be added as required, but are not limited to this. In the present embodiment, the standard length is the length from the heel to the toe of the sole of the corresponding model, the standard width is the width of the sole 7 of the corresponding model, the first standard slope is the slope of the designated area 72 in the first direction X, and the second standard slope is the slope of the designated area 72 in the second direction Y. In other embodiments, the various size parameters of the sole corresponding to the aforementioned detection items can also be set as required, but are not limited to this.
[0035] It is worth mentioning that in this embodiment, the allowable range of the aforementioned parameters of the standard size group is a pre-set value of plus or minus 2%, and the detection condition is that the detection size group is different from the standard size group, that is, when the values of the detection size group fall outside the allowable range of the standard size group, the control unit 6 drives the deflection unit 5 to push the corresponding sole 7 on the conveying unit 3 out of the side opening 214. In other implementations, the detection condition can also be set as required that when the detection size group is the same as the standard size group, the control unit 6 drives the deflection unit 5, but is not limited to this.
[0036] During operation, the operator places the soles 7 to be inspected one by one on the conveying unit 3 and against the limiting member 23, so that each of the soles 7 can be located in a better position to be photographed. Then, the soles 7 pass under the first image capture group 42 and the second image capture group 43 in sequence. After the control unit 6 obtains the model information and the size information corresponding to the soles 7, it selects the corresponding standard size group to compare with the size information. When the inspection size group matches the standard size group, it can pass through the deflection unit 5 and the discharge port 213. When the inspection size group does not match the standard size group, the deflection unit 5 allows the sole 7 to pass through the side opening 214.
[0037] Compared with the existing detection process, the utility model can directly obtain various size data of the sole 7 through the detection unit 4, and the sole 7 can remain in a free state without being interfered by the fixture. Then, the control unit 6 controls the conveying unit 3 and the deflection unit 5, so as to semi-automatically detect and screen multiple soles 7. It can also be applicable to soles 7 of various sizes or shoe types, thereby achieving the effect of improving measurement accuracy and saving manpower.
[0038] In summary, the 3D inspection machine for shoe soles of the present invention can indeed achieve the purpose of the present invention.
