Example 1

Referring to fig. 1,2 and 3, the present embodiment provides a product inspection machine 100 for visually inspecting the appearance of a product to be inspected to determine whether the appearance of the product to be inspected has defects.

In this embodiment, the product to be inspected may be a metal ring of a camera, so that in particular, the embodiment provides a metal ring appearance detector for a mobile phone camera. Of course, in some embodiments, other annular components may be selected for the product to be inspected. In this embodiment, a metal ring of the camera (hereinafter, referred to as a product) is used for illustration, and it is understood that the illustration is not a limitation of the protection scope of the present application.

The product inspection machine 100 provided in this embodiment includes a first frame 110, a first inspection device 120, and two conveying devices 130. The first frame 110 is supported on the foundation, and the two conveying devices 130 and the first detecting device 120 are both disposed on the first frame 110.

Further, the two conveying devices 130 are movably disposed on the first frame 110, and the two conveying devices 130 are arranged in parallel, and the two conveying devices 130 are respectively used for conveying the product along the first direction. The detecting device is used for collecting image information of the products on the two conveying devices 130 so as to perform visual detection on the appearance of the products, and further judge the defect condition of the appearance of the products to be detected.

Therefore, the product detection machine 100 provided by the embodiment has the advantages that the whole detection process is completed by the machine, automatic detection is realized, the labor intensity is reduced, and the detection efficiency is improved. Meanwhile, the problems of missed detection and uneven detection results are avoided, and further the quality of the subsequent use of the product is guaranteed, namely the quality of a camera using the detected product is indirectly guaranteed.

Referring to fig. 3 and 4, in the present embodiment, two conveying devices 130 alternately convey the product to the first detecting device 120. And the two conveying devices 130 do not interfere in motion during the process of conveying the product.

Wherein the routes of the two conveying devices 130 for conveying the products are located in the same vertical plane passing through the first direction, and the routes of the two conveying devices 130 for conveying the products are overlapped.

Specifically, the two conveying devices 130 convey products in a spatially avoiding manner when conveying the products alternately, so as to avoid motion interference during conveying.

Specifically, the two conveying devices 130 include a first linear module 131 and a loading module 132. The first linear module 131 is disposed on the first frame 110, and the material loading module 132 is disposed at an output end of the first linear module 131, where the first linear module 131 is used for driving the material loading module 132 to move along the first direction. The loading modules 132 of the two conveying devices 130 are located on the same line along the first direction, so that the moving routes of the two loading modules 132 are located in the same vertical plane passing through the first direction under the driving of the corresponding first line modules 131.

Further, the carrier module 132 includes a first lifting assembly 1320, a carrier 1321 and a carrier fixture 1322. The first lifting assembly 1320 is disposed at an output end of the first linear module 131, and thus, the first lifting assembly 1320 is driven by the first linear module 131 to move along a first direction. The carrier 1321 is disposed at an output end of the first lifting assembly 1320, that is, the carrier 1321 moves along with the first lifting assembly 1320 along the first direction. Wherein, the first lifting assembly 1320 is configured to drive the carrier 1321 to move along a second direction, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the plane of the rack (in the illustration of the present embodiment, the first direction is indicated by the letter "X" and the second direction is indicated by the letter "Z"). The material loading fixture 1322 is disposed on the material loading frame 1321, and is used for positioning a product, and the material loading fixture 1322 moves along with the material loading frame 1321. Wherein, the loading jigs 1322 on the two loading modules 132 are located in the same vertical plane passing through the first direction.

It can be appreciated that the first linear module 131 drives the first lifting assembly 1320 to move the carrier 1321 back and forth along the first direction, so as to achieve feeding and returning of the carrier 1321. Since the first linear modules 131 of the two conveying devices 130 are alternately conveyed, when one first linear module 131 performs a feeding operation, the other first linear module 131 performs a returning operation, so that the two first linear modules 131 move toward each other in the conveying process of the carrier 1321.

Further, in order to avoid the interference of movement when two carriers 1321 meet, the carriers 1321 on at least one of the two first linear modules 131 need to be driven to move along a second direction, for example, to rise or fall along the second direction by the corresponding first lifting component 1320, so that the carriers 1321 can be spatially staggered when meeting with another carrier 1321 moving towards each other, and spatial avoidance is achieved. Therefore, the transposition of the two material carrying frames 1321 is completed in a space avoiding mode, so that alternate and circular conveying of products to be detected is ensured, and conveying efficiency is greatly improved.

Further, in this embodiment, the carrier 1321 in the return stroke may be set to avoid the carrier 1321 in the feeding, that is, the carrier 1321 in the return stroke is driven by the corresponding first lifting component 1320 to rise or fall along the second direction, so as to avoid the carrier 1321 in the feeding, and further ensure that the product on the carrier 1321 in the feeding is kept on the same horizontal line along the first direction from the feeding to the detecting in the whole feeding process, so that the product on the carrier 1322 is conveyed more stably, and the position accuracy in the product detection is ensured, thereby ensuring the detection accuracy. Of course, in some embodiments, the carrier 1321 in the feeding state may also be set to avoid the carrier 1321 in the return state.

Alternatively, the first linear module 131 may be selected from a motor screw structure, an electric push rod, a linear motor, a cylinder, or an oil cylinder.

The first lift assembly 1320 includes a first carriage 1320a and a first lift drive 1320b, the first carriage 1320a being coupled to an output of the first linear module 131. The first elevating driving part 1320b is installed at one side of the first carriage 1320a, and an output end of the first elevating driving part 1320b is connected to the carriage 1321 to drive the carriage 1321 to move in the second direction.

Alternatively, the first elevating driving 1320b may be selected as a motor screw structure, an electric push rod, a linear motor, a cylinder, or an oil cylinder.

In some embodiments, the carrier fixture 1322 is in a rotational fit with the carrier rack 1321. The material loading module 132 further includes a rotating assembly 1323, the rotating assembly 1323 is disposed on the material loading frame 1321, and an output end of the rotating assembly 1323 is connected to the material loading fixture 1322.

When the detection is performed, the rotating component 1323 drives the material loading fixture 1322 to rotate the product around the second direction. At this time, the visual detection module can acquire a rectangular image, so that more comprehensive image information can be obtained. Optionally, the rotating assembly 1323 is a motor.

Referring to fig. 5 and fig. 6 together, in the present embodiment, the first detecting device 120 includes a first detecting frame 121 and a first vision detecting module 122, the first detecting frame 121 is disposed on the first frame 110, and the first vision detecting module 122 is disposed on the first detecting frame 121. The first visual detection module 122 is used for collecting image information of a product for visual detection.

Further, the first vision inspection module 122 includes a first camera module 1220 and a first light source module 1221. The first camera assembly 1220 is used to capture image information of the top surface or side surface of the product. The first light source module 1221 is configured to provide illumination to the first camera module 1220 to ensure sharpness of the captured image by the first camera module 1220.

Referring to fig. 2, 3 and 4, in some embodiments, a plurality of loading jigs 1322, such as two, three, four, five, six or other numbers, are disposed on the loading rack 1321. The number of the rotating components 1323 corresponds to the number of the material carrying jigs 1322, and each material carrying jig 1322 is correspondingly provided with a product. Therefore, the first visual inspection module 122 can detect the products on the loading jigs 1322 one by one.

In some embodiments, the first visual inspection modules 122 corresponding to the number of the loading jigs 1322 are disposed on the loading rack 1321, so that the first visual inspection modules 122 can complete the inspection of the metal on all the loading jigs 1322 at one time. It is to be understood that the foregoing is illustrative only and is not to be construed as limiting the scope of the application.

Example two

Referring to fig. 2,3, 4 and 5, a product inspection machine 100 is provided in the present embodiment. The present embodiment is an improvement made on the technical basis of the first embodiment described above, and is different from the first embodiment described above in that:

In this embodiment, the first detecting device 120 is configured to perform visual detection on the appearance of the side of the product, that is, the shooting end of the first camera assembly 1220 in the first visual detecting module 122 faces the side of the product, so as to collect image information of the side of the product.

Further, six loading jigs 1322 are disposed on the loading rack 1321 in each conveying device 130. Thus, the carrier 1321 can position six products at a time by using the six carrier jigs 1322, and the first detecting device 120 can complete visual detection of six products at the same time.

Specifically, the first detecting device 120 includes two first detecting frames 121, the two first detecting frames 121 are symmetrically arranged on the first frame 110 with respect to the first direction, and the two conveying devices 130 are located between the two first detecting frames 121. Three first visual inspection modules 122 are arranged on the two first inspection frames 121, wherein the first visual inspection modules 122 on the two first inspection frames 121 are arranged in a staggered manner, and first camera assemblies 1220 in the first visual inspection modules 122 on the two first inspection frames 121 are oppositely arranged, and each first camera assembly 1220 corresponds to one first light source assembly 1221.

Further, the distance between two adjacent first camera assemblies 1220 on the same first detection frame 121 is 2 times the distance between two adjacent material loading jigs 1322 on the material loading frame 1321, so as to realize the dislocation detection of the products on the same material loading frame 1321.

It will be appreciated that the first camera assemblies 1220 of the three first vision inspection modules 122 on one of the first inspection racks 121 are respectively used to collect image information of the first, third and fifth product sides on the carrier 1321, and the first camera assemblies 1220 of the three first vision inspection modules 122 on the other one of the first inspection racks 121 are respectively used to collect image information of the second, fourth and sixth products on the carrier 1321, so that the simultaneous inspection of six products on the carrier 1321 can be realized.

Since the first camera assembly 1220 itself is larger in size than the product, if six first vision inspection modules 122 are disposed on only one first inspection frame 121 to inspect six products, it is necessary to design the interval between two adjacent carrier jigs 1322 on the carrier 1321 to be matched with the distance between two adjacent first camera assemblies 1220 on the first inspection frame 121, thereby resulting in an increase in the length of the carrier 1321 in the first direction, and an increase in the travel distance that the product needs to be conveyed, thereby indirectly increasing the size of the product inspection machine 100. Therefore, the product inspection machine 100 provided in this embodiment employs the dislocation inspection method by arranging two first inspection frames 121, so as to shorten the size of the material carrying frame 1321, shorten the conveying stroke, and further make the overall structure of the product inspection machine 100 more compact.

Example III

Referring to fig. 1, 2 and 3, a product inspection machine 100 is provided in the present embodiment. The present embodiment is an improvement made on the technical basis of the first or second embodiment, and is different from the first or second embodiment in that:

In this embodiment, the number of the first detecting devices 120 is plural, the plural first detecting devices 120 are sequentially arranged along the first direction, each first detecting device 120 is used for executing different detecting procedures, and the plural first detecting devices 120 share two conveying devices 130, and the conveying devices 130 alternately convey the products to the plural first detecting devices 120 in sequence for visual detection.

In some embodiments, the plurality of first detecting devices 120 may be divided into a first side detecting device 120a, a second side detecting device 120b, and a top detecting device 120c along the first direction according to the item detected by each first detecting device 120. The first side detecting device 120a and the second side detecting device 120b are respectively configured to detect defects of different side appearances of the product, and the first side detecting device 120a and the second side detecting device 120b have the same structure and can directly select the scheme of the first detecting device 120 provided in the second embodiment.

Referring to fig. 6, the top surface detecting device 120c is configured to visually detect an appearance of a top surface of a product, so that in the present embodiment, the first camera component 1220 in the top surface detecting device 120c is located above the loading fixture 1322, and a shooting end of the first camera component 1220 faces downward. Thus, when the product is conveyed under the first camera assembly 1220 of the top surface inspection device 120c, the first camera assembly 1220 may capture image information of the top surface of the product.

In the second step, the second lifting module 220 drives the material taking module 230 to descend along the second direction by a predetermined height, so that the material taking module 230 can grasp the product. In the third step, the second lifting module 220 drives the material taking module 230 to lift and reset along the second direction. In the fourth step, the second linear module 210 continues to drive the second lifting module 220 to drive the material taking module 230 to move to the second preset position along the first direction, so that the material taking module 230 corresponds to the material loading fixture 1322 of the next detection process. Fifth, the second lifting module 220 repeats the driving of the second step, so that the material taking module 230 places the product on the material loading fixture 1322 of the detecting process, and the carrying is completed.
